Referring to fig. 1, a partial block diagram of a vehicle meter is provided.
Structurally, the vehicle instrument has a central axle 110 and a bracket 100. The bracket 100 is provided with an upper bearing 120 and a lower bearing 140, and both ends of the central shaft 110 are respectively installed in the upper bearing 120 and the lower bearing 140, so that the central shaft 110 can flexibly rotate.
The upper bearing 120 is a pipe having external threads, the upper bearing 120 is coupled to the bracket 100 by threads, and a first nut 130 is screwed on the outer side of the upper bearing 120. When assembling, the first nut 130 is screwed with the upper bearing 120 and the bracket 100 fixed, so that the end surface of the first nut 130 is tightly attached to the bracket 100, and the upper bearing 120, the bracket 100 and the first nut 130 are fixed together.
In design, the middle shaft 110 is inserted into the lower bearing 140, and the middle shaft 110 can move along the axial direction.
The maximum gap between the bottom bracket 110 and the lower bearing 140 should be controlled in design, particularly, the gap along the axial direction of the bottom bracket 110, thereby ensuring that the end of the bottom bracket 110 is located in the lower bearing 140 and that the meter can be used permanently and reliably.
The center shaft 110 is limited by the end of the upper bearing 120 in design, that is, by controlling the position of the upper bearing 120, it is ensured that the maximum gap between the center shaft 110 and the lower bearing 140 is within the control range.
In the manufacturing process, the operator sequentially assembles the upper bearing 120 and the first nut 130, but the upper bearing 120 is easily rotated together with the first nut 130 during the assembling process, so that it is difficult to precisely control the position of the upper bearing 120, that is, to control the gap between the bottom bracket 110 and the lower bearing 140.
In measurement, the protruding height of the middle shaft 110 is detected first, and then the gap between the middle shaft 110 and the lower bearing 140 is calculated through the specification and the size of the upper bearing 120 and the middle shaft 110, but the upper bearing 120 and the middle shaft 110 have deviation in manufacturing, and the calculated gap has deviation from the actual situation.
To solve the problems in manufacturing and inspection, as shown in fig. 2, an integrated machine for assembling and inspecting a vehicle meter is provided.
Specifically, the integrated machine has a table 200.
On the table 200, as shown in fig. 2 and 4, there are a positioning block 210 for mounting the bracket 100 of the vehicle instrument, and a first cylinder 240 for translating the positioning block 210.

The first cylinder 240 is provided so that the positioning block 210 has two positions, one for assembling the bracket 100 with the upper bearing 120 and one for disassembling the load, thereby preventing injury to the operator.
For assembly, the table 200 is provided with two uprights 260, a cross member 270 and a lifting frame 300.
The cross beam 270 connects the top ends of the two upright posts 260, so as to improve stability of the upright posts 260, and simultaneously, the two upright posts 260 are slidably connected with the lifting frame 300, so that accurate movement of the lifting frame 300 is ensured, and the lifting frame is not deviated.

To avoid the lift runout, two third cylinders 280 are provided and are disposed adjacent to the upright post 260.
For the lifting frame 300, there are two parallel plates, an upper mounting plate 361, a lower mounting plate 362 and a sleeve, the upper mounting plate 361 is connected with the third cylinder 280, the sleeve is sleeved on the upright post 260, and at the same time, the sleeve fixes the upper mounting plate 361 and the lower mounting plate 362 together.
Meanwhile, in order to realize the assembly function of the upper bearing 120, the first nut 130 and the bracket 100, the lower mounting plate 362 is provided with an outer tube 310 having a function of driving the first nut 130 of the meter to rotate, the upper mounting plate 361 is provided with a middle tube 320 driving the upper bearing 120 of the meter to rotate, and the middle tube 320 is sleeved on the inner side of the outer tube 310.
The outer tube 310 is arranged on the lower mounting plate 362, the middle tube 320 is arranged on the upper mounting plate 361, and then the middle tube 320 is positioned on the inner side of the outer tube 310, so that the structure is simple, and the assembly and the maintenance are convenient.
That is, the disassembly of the intermediate tube 320 may be achieved by disassembling the intermediate tube 320 from the upper mounting plate 361, and the disassembly of the outer tube 310 may be achieved by disassembling the outer tube 310 from the lower mounting plate 362, thereby achieving the separation of the outer tube 310 and the intermediate tube 320.
In order to drive the outer tube 310 and the middle tube 320 to rotate and further realize the assembly function, the lower mounting plate 362 is provided with the first motor 340, the upper mounting plate 361 is provided with the second motor 350, the first motor 340 and the second motor 350 are arranged between the upper mounting plate 361 and the lower mounting plate 362, the first motor 340 drives the outer tube 310 to rotate, and the second motor 350 drives the middle tube 320 to rotate.
The first motor 340 and the second motor 350 are preferably stepper motors to facilitate control of the number of turns.
Meanwhile, the first motor 340 and the second motor 350 are disposed between the upper mounting plate 361 and the lower mounting plate 362, so that the height of the apparatus can be effectively reduced, and the occupied space can be reduced.
Meanwhile, the upper mounting plate 361, the middle pipe 320 and the second motor 350 can be integrally assembled and disassembled relative to the lower mounting plate 362, so that the debugging difficulty in maintenance is reduced.
In order to measure the gap between the middle shaft 110 and the lower bearing 140 of the instrument, an inner core 330 is disposed on the inner side of the middle tube 320, when the lifting frame 300 is located at the low point of the lifting stroke, the bottom end of the inner core 330 can be abutted to the top end of the middle shaft 110, meanwhile, the upper mounting plate 361 is further provided with a micrometer 360, and the measuring arm of the micrometer 360 stretches up and down to be abutted to the top end of the inner core 330.
Meanwhile, to ensure accurate measurement, the workbench 200 is provided with a deflector rod 220 and a second cylinder 250 for driving the deflector rod 220 to lift.
As illustrated, the second cylinder 250 and the lever 220 are both disposed on the first frame 230, thereby reducing manufacturing costs.
When a measurement is required, the lifting frame 300 descends, the bottom end of the inner core 330 abuts against the top end of the central shaft 110, and accordingly, the top end of the inner core 330 lifts the measuring arm of the micrometer 360, and the indication number of the micrometer 360 is not zero.
Then, the second cylinder 250 is operated to make the lever 220 dial the middle shaft 110 upwards, so that the middle shaft 110 is lifted until the middle shaft 110 is abutted and fixed with the upper bearing 120, at this time, the lifting distance of the middle shaft 110 is equal to the maximum gap between the middle shaft 110 and the lower bearing 140, and also equal to the difference between the readings of the micrometer 360 before and after, if the readings of the micrometer 360 are zeroed before the second cylinder 250 is operated, the maximum gap is equal to the current readings of the micrometer 360.
The capacitance grid micrometer 360 can be selected for the micrometer 360, thereby facilitating purchase and application.
In order to avoid impact caused by the descending of the lifting frame 300, at the same time, the position of the support 100 is conveniently confirmed, a buffer column 366 for abutting against the support 100 is arranged at the bottom of the lifting frame 300, and the buffer column 366 is matched with the positioning block 210 to fix the support 100.
That is, when the elevation frame 300 is lowered to the lowest point, the support frame 100 can be fixed by the buffer columns 366 contacting the support frame 100, on the one hand, and on the other hand, the position between the support frame 100 and the components on the elevation frame 300 can be made accurate.
The bumper post 366 may have a rubber pad to reduce shock, or a resilient mounting structure to both reduce shock and provide a defined dimensional space.
In some embodiments, for easy installation, a second frame 363 is disposed on a top surface of the upper mounting plate 361, and the micrometer 360 is disposed on the second frame 363.
The micrometer 360 is arranged on the second rack 363, so that the number of parts is increased, and the installation and adjustment are convenient.
Meanwhile, the top surface of the upper mounting plate 361 is provided with a first bearing 364, the first bearing 364 supports the top end of the inner core 330, and the inner core 330 is provided with a flange overlapping the first bearing 364.
Thus, the inner core 330 can be rotated without interfering with the movement of the middle tube 320, and the rim can prevent the inner core 330 from falling out of the middle tube 320.
In some embodiments, the cross beam 270 may be provided with a first mouth 290, the first mouth 290 receiving the micrometer 360 therethrough.
As shown in fig. 3, in order to smoothly drive the first nut 130 to rotate by the outer tube 310, the outer tube 310 may include a lower half tube 311 abutting against the upper end surface of the first nut 130, and an upper half tube 312 in driving connection with the first motor 340, where the upper half tube 312 is slidably connected with the lower half tube 311 up and down, and a supporting spring 313 is disposed between the lower half tube 311 and the upper half tube 312.
That is, the supporting spring 313 makes the lower half pipe 311 tightly attached to the first nut 130, which can conveniently drive the first nut 130 to rotate, and correct the situation that the first nut 130 is not completely sleeved in the upper bearing 120 in the initial state, and simultaneously, when the first nut 130, the upper bearing 120 and the bracket 100 are locked, the lower half pipe 311 slides with the first nut 130, so as to avoid the damage of the first nut 130 or the lower half pipe 311.
Similarly, the middle tube 320 is designed similar to the outer tube 310, so that the installation quality of the upper bearing 120 is ensured.
For easy installation, the lower mounting plate 362 may be provided with a second bearing 365 connected to the upper half pipe 312, the top end of the support spring 313 is abutted against the second bearing 365, and the bottom end of the support spring 313 is abutted against the lower half pipe 311.
For ease of transmission, the upper tube 312 should be rectangular or polygonal in cross section.
And, the lower end of the upper half pipe 312 should be inserted into the lower half pipe 311 without affecting the installation of the support spring 313.
The support springs 313 are preferably sleeved on the upper half tube 312 to reduce the occupied space, but other manners are also possible.
In order to avoid the loosening of the lower half pipe 311, a limiting groove 314 extending up and down may be provided at the bottom end of the upper half pipe 312, and the lower half pipe 311 may be provided with a limiting pin 315 inserted into the limiting groove 314.
In summary, the working principle of this embodiment is:
1. in assembly, the fixing of the bracket 100, the upper bearing 120 and the first nut 130 is achieved by the rotation of the outer tube 310 and the middle tube 320, and the number of rotations of the middle tube 320 is controlled by the second motor 350, thereby defining the installation position of the upper bearing 120, specifically, the upper bearing 120 can be rotated to the bottom, then the upper bearing 120 is retracted by the corresponding number of rotations, the upper bearing 120 is lifted by a distance equal to the maximum gap between the middle shaft 110 and the lower bearing 140 when the upper bearing 120 is retracted, and then the outer tube 310 is rotated, so that the bracket 100 and the upper bearing 120 are fixed by the first nut 130.
The specific assembly method is as follows:
① The third cylinder 280 drives the lifting frame 300 to descend, so that the buffer post 366 and the positioning block 210 cooperate with the fixed bracket 100, and simultaneously, the outer tube 310 is pressed against the first nut 130, and the middle tube 320 is pressed against the upper bearing 120.
② The first motor 340 rotates, and then, drives the outer tube 310 to rotate, so that the first nut 130 rotates to descend, and thus, the first nut 130 is completely sleeved in the upper bearing 120, and the first nut 130 is prevented from being loosened when the upper bearing 120 rotates.
③ The first motor 340 rotates reversely to raise the first nut 130, so that a gap is reserved between the first nut 130 and the bracket 100, and the rotation of the upper bearing 120 is not affected.
④ The first motor 340 is stopped and the second motor 350 is rotated such that the upper bearing 120 is rotated down until the upper bearing 120 cannot continue to rotate, at which time the gap between the bottom bracket 110 and the lower bearing 140 is zero.
⑤ The second motor 350 rotates reversely to lift the upper bearing 120, and the upper bearing 120 is lifted by a distance equal to the maximum gap between the middle shaft 110 and the lower bearing 140.
⑥ The second motor 350 is stopped, and the first motor 340 rotates, so that the first nut 130 ascends, ensuring that the first nut 130 is not jammed.
⑦ The first motor 340 rotates reversely, the first nut 130 descends, and the bracket 100 and the upper bearing 120 are fixed together, thereby completing the assembly.
⑧ The third cylinder 280 drives the lifting frame 300 to lift, so that the outer tube 310 is separated from the first nut 130, the middle tube 320 is separated from the upper bearing 120, and then the first cylinder 240 drives the positioning block 210 to return, so that the operator can disassemble and charge.
2. In detection, the center shaft 110 is lifted, so that the center shaft 110 lifts the inner core 330 and the measuring arm of the micrometer 360, the actual gap is determined through the indication change, the conversion error is reduced, and particularly, the influence caused by the manufacturing difference of the upper bearing 120 is avoided.
