Technical Field

The utility model relates to the field of bearing processing equipment, in particular to a grinding machine positioning device used for bearing processing.

Background Art

The basic components of a bearing: inner ring, outer ring, rolling element, and cage. Inner ring: often fits tightly with the shaft and rotates together. Outer ring: often fits in transition with the bearing seat, and mainly serves as a support. Rolling elements: are evenly arranged in the grooves of the inner and outer rings with the help of cages. Its shape, size, and number directly affect the load-bearing capacity and performance of the bearing. Cage: in addition to evenly separating the rolling elements, it also guides the rotation of the rolling elements and effectively improves the internal lubrication performance of the bearing. The bearing fixture can clamp and fix the bearing. It is a bearing processing auxiliary equipment and is widely used in the bearing processing and production process.

The bearing fixture in the existing technical solution cannot be used to clamp bearings of different outer diameters due to its relatively simple structure. This leads to limitations in the bearing fixture when producing and processing bearings, which in turn affects the production efficiency of the bearings.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

1. Due to the use of the bottom plate, support block, first drive device, clamping device, support frame and circular perforation, when the bearing needs to be clamped during the production and processing of the bearing, the staff first extends the telescopic end of the first drive device to drive the support block to move to the position that matches the two sets of clamping devices. At this time, the staff places the bearing on the support block, and then the staff works through the two sets of clamping devices at the same time, so that the two sets of clamping devices move close to the bearing direction at the same time, and the two sets of clamping devices are against the outer ring of the bearing at the same time, so that the bearing can be fixed between the two sets of clamping devices, and then the staff retracts the telescopic end of the first drive device and drives the support block to reset, and the clamping work of the bearing can be completed. The whole operation process is simple and reliable, which is convenient for the staff to operate. At the same time, the spacing between the two sets of clamping devices can be automatically adjusted according to the outer diameter of the bearing, so that the two sets of clamping devices can be used for clamping and fixing bearings with different outer diameters, thereby improving the practicality of the positioning device to a certain extent.

2. Due to the use of the slider, arc block, second drive device, limit slide rail, bending rod, gear and rack, when the bearing is placed on the support block and needs to be fixed by two sets of clamping devices, the staff drives the gear to rotate through the output shaft of the second drive device. Since the gear is meshed with the rack, and the sliders arranged on the second drive device are respectively slidably connected to the two sets of limit slide rails, when the gear rotates, the slider can slide back and forth on the two sets of limit slide rails. Since the arc block is fixedly connected to the slider through the bending rod, the slider can move the arc block during the sliding process. When the two sets of arc blocks move close to the bearing direction at the same time and abut against the outer ring of the bearing, the bearing can be well fixed at this time. Since the spacing between the two sets of arc blocks can be adjusted by rotating the output shaft of the second drive device, the two sets of arc blocks can clamp and fix bearings of different outer diameters.

3. Due to the setting of the damping block, when the arc-shaped block abuts against the outer ring of the bearing, the damping block can increase the friction between the arc-shaped block and the outer ring of the bearing, thereby enabling the two sets of arc-shaped blocks to clamp and fix the bearing better.

4. Since the support block is made of soft material, when the bearing is placed on the support block, it can prevent the support block from causing unnecessary wear to the bearing, thereby playing a certain protective role for the bearing.

DETAILED DESCRIPTION

The embodiment of the present application provides a grinding machine positioning device for bearing processing, thereby solving the technical problem that the bearing fixture in the prior art solution cannot be used for clamping bearings of different outer diameters at the same time due to its relatively simple structure. This leads to limitations in the production and processing of bearings, which in turn affects the production efficiency of bearings.

The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

A grinding machine positioning device for bearing processing, as shown in FIG1, comprises a base plate 1, a support block 2 for supporting a bearing, a first driving device 3 for driving the support block 2 to rise and fall, a clamping device 4 for clamping the bearing, and a support frame 5 arranged on the base plate 1. The support block 2 is arranged on the telescopic end of the first driving device 3. The first driving device 3 is mounted on the base plate 1. Two groups of clamping devices 4 are symmetrically arranged on the support frame 5. A circular through hole 51 is opened on the support frame 5 at a position corresponding to the support block 2.

The support frame 5 is fixedly connected to the top of the base plate 1. The first driving device 3 is preferably a cylinder. The support block 2 is fixedly connected to the telescopic end of the first driving device 3. The first driving device 3 is fixedly connected to the top of the base plate 1. Two groups of clamping devices 4 are fixedly connected to the top of the support frame 5 and are symmetrically arranged with the support block 2. A circular through hole 51 is opened on the support frame 5 at a position corresponding to the support block 2, and the circular through hole 51 can facilitate the telescopic end of the first driving device 3 to be telescopic.

Due to the arrangement of the bottom plate 1, the support block 2, the first driving device 3, the clamping device 4, the support frame 5 and the circular perforation 51, when the bearing needs to be clamped during the production and processing of the bearing, the staff first extends the telescopic end of the first driving device 3 to drive the support block 2 to move to the position adapted between the two sets of clamping devices 4. At this time, the staff places the bearing on the support block 2, and then the staff simultaneously works through the two sets of clamping devices 4, so that the two sets of clamping devices 4 move close to the bearing direction at the same time, and the two sets of clamping devices 4 are simultaneously against the outer ring of the bearing, and the bearing can be fixed between the two sets of clamping devices 4. Then the staff retracts the telescopic end of the first driving device 3 and drives the support block 2 to reset, and the clamping work of the bearing can be completed. The whole operation process is simple and reliable, and it is convenient for the staff to operate. At the same time, the spacing between the two sets of clamping devices 4 can be automatically adjusted according to the outer diameter of the bearing, so that the two sets of clamping devices 4 can be used for clamping and fixing bearings with different outer diameters, thereby improving the practicality of the positioning device to a certain extent.

As shown in Fig. 2 and Fig. 3, the clamping device 4 includes a slider 41, an arc-shaped stopper 42 for abutting against the outer ring of the bearing, a second driving device 43 for driving the slider 41 to slide, a limiting slide rail 44 for limiting the sliding movement of the slider 41, a bending rod 45 arranged on the slider 41, a gear 46 arranged on the output shaft of the second driving device 43, and a rack 47 arranged on the support frame 5. Two groups of symmetrically placed limiting slide rails 44 are arranged on the support frame 5. The two ends of the slider 41 are slidably connected to the two groups of limiting slide rails 44. The arc-shaped stopper 42 is arranged on the bending rod 45. The second driving device 43 is installed on the slider 41. The gear 46 is meshed and connected with the rack 47.

Two sets of symmetrically placed limiting rails 44 are fixedly connected to the top of the support frame 5. The arc stopper 42 is fixedly connected to the bending rod 45. The bending rod 45 is fixedly connected to the top of the slider 41. The second drive device 43 is detachably fixedly mounted on the bottom of the slider 41 by bolts. The second drive device 43 is preferably a servo motor. The gear 46 is fixedly connected to the output shaft of the second drive device 43. The rack 47 is fixedly connected to the top of the support frame 5.

Due to the arrangement of the slider 41, the arc block 42, the second drive device 43, the limit slide rail 44, the bending rod 45, the gear 46 and the rack 47, when the bearing is placed on the support block 2 and needs to be fixed by two sets of clamping devices 4, the staff drives the gear 46 to rotate through the output shaft of the second drive device 43. Since the gear 46 is meshed and connected with the rack 47, and the slider 41 arranged on the second drive device 43 is slidably connected to the two sets of limit slide rails 44, when the gear 46 rotates, the slider 41 can slide back and forth on the two sets of limit slide rails 44. Since the arc block 42 is fixedly connected to the slider 41 through the bending rod 45, the slider 41 can realize the movement of the arc block 42 during the sliding process. When the two sets of arc blocks 42 move close to the bearing direction at the same time and abut against the outer ring of the bearing, the bearing can be well fixed at this time. Since the distance between the two groups of arc-shaped stops 42 can be adjusted by rotating the output shaft of the second driving device 43 , bearings with different outer diameters can be clamped and fixed between the two groups of arc-shaped stops 42 .

As shown in Fig. 4, the clamping device 4 further includes a damping block 48. The arc-shaped stopper 42 is provided with a plurality of groups of damping blocks 48 arranged in an arc-shaped array.

A plurality of groups of damping blocks 48 arranged in an arc-shaped array are fixedly connected to one surface of the arc-shaped stopper 42 for abutting against the bearing.

Due to the provision of the damping block 48, when the arc-shaped stopper 42 abuts against the outer ring of the bearing, the damping block 48 can increase the friction between the arc-shaped stopper 42 and the outer ring of the bearing, thereby enabling the two sets of arc-shaped stoppers 42 to clamp and fix the bearing better.

As shown in FIG. 1 , the support block 2 is preferably made of a soft material, such as rubber and PVC.

Since the support block 2 is made of a soft material, when the bearing is placed on the support block 2, it can prevent the support block 2 from causing unnecessary wear to the bearing, thereby playing a certain protective role for the bearing.
