Description

[Detailed Description of the Invention] This invention relates to an engine jig for supporting an engine at a predetermined position and attitude on a conveyor line in an assembly line for automobiles, etc.

The engine jig according to this invention is used in the process of mounting the chassis of the engine, that is, suspending the chassis on a conveyor that is transporting the engine, and assembling the engine to the chassis on the conveyor. It will be done.

Automotive assembly lines are required to be used in common for the assembly of multiple vehicle models in order to increase the line's operating efficiency and reduce equipment costs.

Therefore, there is a demand for an engine jig used in the process of mounting the engine onto the chassis of the engine so that one jig can be used in common for many types of engines.

The purpose of this invention is to meet the above-mentioned demands and to provide an engine jig that allows easy attachment and detachment of an engine to the jig.

This invention will be described in detail below with reference to the accompanying drawings.

1 is a base plate, 2 is a table, 3 is a rotary cylinder, 4 is a front and rear support, 5 is a seat made of urethane rubber, 6 is a left support, and γ is a right support.

The substrate 1 is placed and fixed on the top surface of a conveyor (not shown),
It rotates endlessly along with the conveyor up and down a conveyor pit (not shown).

As shown in FIG. 2, a table 2 disposed on the upper surface of the substrate 1 is pivotably supported on the substrate 1 via a bearing 8 so as to be rotatable around a vertical axis.

In order to eliminate the inclination of the table 2 during its rotation, rollers 9 are provided at four locations on the substrate 1, front, rear, left, and right, to catch the peripheral edge of the table 20 from below.

The rotation angle of the table 2 is determined by the rotation angle of the board 1. , the angle is limited to 90 degrees up to a position where the other of the locking protrusions 11 is received by the other engaging protrusion (not shown).

Then, at the end of the warping rotation stroke, by inserting the index pin 13 into the index hole 12 drilled in the table 2,
This allows the table 2 to be fixed.

The index pin 13 is urged by a spring 14 to automatically enter the index hole 12, and is pulled out from the index hole 12 downward by later pulling the release lever 15.

A rotary cylinder 3 is rotatably installed around a longitudinal axis on a left-right support column 4 erected on a table 2.

An indexing device 19 is constituted by an indexing plate 16 fixed to the front end of the rotary cylinder 3 and indexing pins 18 which are selectively inserted into five indexing holes 1γ bored in the indexing plate 16.

This indexing device 19 allows the rotary cylinder 3 to be fixed at one of five preselected phase positions.

The index pin 18 is biased by a spring 20 to automatically enter one of the index holes 12.

The index pin 18 is pulled out from the index hole 11 by grasping the end of the index pin 18 by hand and pulling it forward.

The rotary cylinder 3 is formed into a rectangular cylindrical shape, and each of its outer circumferential planes alternatively becomes an upwardly facing surface in each phase position in which the rotating cylinder 3 is fixed, and a seat 5 fixed to the upwardly facing surface, that is, The engine 21 is placed on the catch seat 5 shown in the actual record.

As shown in FIG. 3, the engine 21 placed on the catch seat 5 is clamped and fixed by urethane rubber clamps 22, 23 and 24 fixed to the upper parts of both the right and left columns 6, 7. Ru.

The right support 6 is fixed to the table 2, and the positions of the clamping thicknesses 22 and 23 fixed to the right support 6 do not change.

The left support γ is divided into a lower part 25 and an upper part 26, and the upper part 26 can swing around the left-right axis between a raised position shown by a solid line in FIG. 1 and a sideways position shown by a two-dot chain line.

27 is a fulcrum pin, 28 is a stopper plate forming a part of the lower part 25, and 29 is an engagement plate extending from the lower end of the upper part 26. By receiving the engagement plate 29 with the stopper plate 28, the upper part 26 can be moved to the upright position. This prevents it from falling forward.

Further, when the upper part 26 is in the sideways position, it is received by a stopper 30 made of urethane rubber that stands up on the table 2.

The remaining clamping thickness 24 is attached to the free end portion, that is, the upper end portion, of a swinging arm 31 that is pivoted to the upper portion 26 of the left support column 1 so as to be swingable around the longitudinal axis.

A spring 32 attached across the upper part 26 and the swinging arm 31 presses the free end of the swinging arm 31 against the circumferential surface of a cam 33 pivotally connected to the upper end of the upper part 26.

The cam 33 is swung by a lever 34 and is shown in FIG.
) By swinging the lever 34 from the upward position shown by the two-dot chain line to the downward position shown by the solid line in the figure, the clamping thickness 24 can be moved to the left by a predetermined stroke of θ, for example, by 20 steps. It is.

Then, the engine 21 on the catch seat 5 is held with a thickness of 22.23.
By clamping the engine 21 with the clamps 24, the engine 21 can be firmly supported at a predetermined position and posture on the conveyor, and the upper part 26 can be prevented from falling sideways due to the reaction force of the clamping.

When attaching or detaching the engine 21, the upper part 26 of the left column 7 can be laid down to a sideways position, so that the work space for attaching and detaching the left column γ is expanded, making the attaching and detaching work easier.

Each receiving surface 35 of each receiving seat 5 is formed with a recess 36 for receiving the lower part of the engine 21 in order to determine the height and attitude of the engine 21.

The shape of the concave portion 36 of each receiving surface 35 is made different depending on the five types of engines 21 conveyed by this conveyor.

By determining the position of the rotary cylinder 3 at a phase position where the receiving surface 35 is facing upward, appropriate depending on the operator or the model of the engine 21, any of these engines 21 can be placed on the conveyor with one engine jig. I can support it.

Furthermore, by switching the phase of the table 2, one engine jig can be used for both horizontally and vertically mounted engines.

Note that 31 indicates a wear-resistant plate.

Further, reference numeral 38 denotes guide rollers for stabilizing the running of the substrate 1.

This invention is based on an indexing device in which a rotary cylinder that rotates around the longitudinal axis is arranged on the top surface of the table as described above, and the rotary cylinder is fixed at a position selected from a plurality of preselected phase positions. Each receiving surface of each catch that receives the engine on the upper side of the rotary cylinder at each position is provided with a recess for receiving a different type of engine. Raise the left and right pillars that receive the water from the table, and also raise one of the left and right pillars
The present invention relates to an engine jig that is capable of swinging around the left and right axis between the upright position and the sideways position, and can be used in common as a jig for multiple engine models.

Further, since one of the left and right columns is a collapsible column, a large space is provided for attaching and detaching the engine, so that the engine can be easily attached to and detached from the engine jig.

Furthermore, if the table is made rotatable around the vertical axis, the orientation of the engine can be changed, making it easier to install and remove the engine. This saves time and effort, making it possible to extremely increase the operating efficiency of the line.
