The specific implementation process is as follows:

when a vehicle body of a certain vehicle type needs to be machined, firstly, the vehicle body to be machined is fixed on a base 1, then general assembly fixtures matched with the vehicle body to be machined are selected (because the vehicle body is of a symmetrical structure, two sides of the vehicle body need to be machined simultaneously when the vehicle body is machined, two general assembly fixtures are needed to simultaneously machine two sides of the vehicle body during actual machining), then a driving motor 3 drives a fixture support 2 to slide to two sides of the base 1, when the fixture support 2 is close to the base 1, a matching block is firstly contacted with a positioning block 403, and under the limiting action of the positioning block 403, the fixture support 2 cannot be continuously close to the base 1 and is limited preliminarily; at this time, the matching roller 201 is located above the projection 502, and then the output shaft of the driving cylinder 6 is shortened, so that the driving cylinder 6 pulls the swing link 7 to rotate along the counterclockwise direction in fig. 4, the right end of the swing link 7 pushes the slide seat 5 to vertically slide upwards, the slide seat 5 drives the projection 502 to move upwards, the guide inclined plane 5021 on the left side wall of the projection 502 in fig. 5 is in contact with the matching roller 201 in fig. 6, the guide inclined plane 5021 has a guiding effect on the matching roller 201, and as the slide seat 5 continues to slide upwards, the guide inclined plane 5021 has a tendency of pushing the matching roller 201 leftwards, so that the matching block on the clamp support 2 is further in abutting fit with the positioning block 403, at this time, the positioning block 403 blocks the clamp support 2 from sliding leftwards, and the guide inclined plane 5021 blocks the clamp support 2 from sliding rightwards, so that the clamp support 2 is completely fixed in the horizontal direction, and because the matching block and the positioning block 403 are in abutting state, the position precision relation of the clamp support 2 and the base 1 can be effectively guaranteed, so that the clamp support 2 is accurately fixed, and the machining of the automobile body is accurately finished by using a general splicing clamp on the clamp support 2.

When the swing rod 7 swings and pushes the sliding seat 5 to slide upwards to the upper limit position, the swing rod 7 drives the trigger plate 9 to rotate through the connecting rod 10, only when the trigger plate 9 rotates to be matched with the inductor 8 close to the upper side in the figure 2 (namely, when the inductor 8 can receive infrared light emitted by the inductor 8 and generate a sensing signal), the fact that the swing rod 7 rotates to a preset position is shown, namely, an accurate matching relation is formed between the guide inclined plane 5021 on the lug 502 and the clamp support 2, the general splicing clamp on the clamp support 2 can be started to process the automobile body at the moment, and the phenomenon that the clamp support 2 processes the automobile body under the condition of not accurately positioning and the processing precision is influenced is avoided.

After the machining is finished, the swing rod 7 is driven to rotate clockwise in the graph 4 by the driving air cylinder 6, so that the swing rod 7 pushes the sliding seat 5 to slide downwards, the limiting effect of the guide inclined surface 5021 on the rightward sliding of the clamp support 2 disappears, the clamp support 2 is pulled to slide towards the direction far away from the base 1 by the driving motor 3, and then the base 1 is conveyed away by the main guide rail in the prior art.

Example two

The difference between the second embodiment and the first embodiment is that, when the assembly jig in the prior art is used for processing the vehicle body, inevitably, the assembly jig applies a force to the vehicle body, so that the jig holder 2 needs to bear a reaction force of the vehicle body to the assembly jig, while the force with which the clamp mount 2 remains engaged with the base 1 comes mainly from the driving cylinder 6, and the compressed gas in the piston chamber of the driving cylinder 6 is theoretically in a compressible state, so that when the force applied to the clamp holder 2 acts on the driving cylinder 6, the gas in the driving cylinder 6 may be compressed, and the piston rod of the driving cylinder 6 is compressed, so that the swing rod 7 swings to affect the locking and positioning effect of the guiding inclined plane 5021 on the projection 502 on the clamp support 2, thereby affecting the fixing precision of the clamp support 2 and further affecting the machining precision of the vehicle body.

In order to enable the car body to be processed more accurately and stably and reduce the situation that the clamp support 2 is not accurately locked and positioned due to the acting force of the assembly clamp in the processing process, as shown in fig. 7, 8 and 9, in the embodiment, a retaining mechanism for driving the guide inclined plane 5021 on the bump 502 and the clamp support 2 to be kept in a matching state is arranged on the locking seat 4, the retaining mechanism comprises a movable plate 11, a vertically arranged strip-shaped hole is formed in the movable plate 11, a fixing screw penetrates through the strip-shaped hole, a threaded hole matched with the fixing screw is formed in the baffle 401, the position of the movable plate 11 in the vertical direction can be adjusted through the strip-shaped hole, then the movable plate 11 can be fixed on the baffle 401 through the fixing screw, a retaining cylinder 12 is fixedly connected on the movable plate 11 through the screw, a limiting block 13 is fixedly connected on the retaining cylinder 12 through the screw, and an extrusion block 14 is fixedly connected at the top of the swing rod 7 through the screw, the limiting block 13 is positioned above the extrusion block 14, the top surface of the extrusion block 14 is provided with a matching inclined plane, the outer wall of the limiting block 13 is provided with a chamfer, so that the outer wall of the limiting block 13 and the top surface of the extrusion block 14 can form a wedge surface fit, when the sliding seat 5 slides to the upper limit position under the action of the swing rod 7, the guiding inclined plane 5021 on the lug 502 is matched with the matching roller 201, after the clamp support 2 is locked and fixed, the retaining cylinder 12 pushes the limiting block 13 to move to the upper part of the extrusion block 14, the limiting block 13 is matched with the wedge surface of the extrusion block 14 and is pressed against each other, the limiting block 13 is utilized to limit and extrude the swing amplitude of the swing rod 7, the swing rod 7 can stably apply acting force to the clamp support 2 through the convex block 502, and the clamp support 2 is ensured to be stably matched with the base 1 accurately, so that the clamp support 2 is prevented from being displaced in the machining of the vehicle body to influence the machining precision of the vehicle body.

EXAMPLE III

The difference between the third embodiment and the first embodiment is that: with reference to fig. 10 and 11, a fixing block 15 is fixedly connected to the outer side wall of the baffle 401 through a screw, a threaded rod 16 is connected to the fixing block 15 through a vertical thread, the threaded rod 16 is located above the movable plate 11, and when the position of the movable plate 11 is adjusted and fixed on the baffle 401, the threaded rod 16 is rotated to enable the bottom end of the threaded rod 16 to abut against the top end of the movable plate 11. When the swing rod 7 rotates to push the sliding seat 5 to slide upwards to the upper limit position, the swing rod 7 abuts against the limiting block 13 to stop rotating, the swing rod 7 has certain impact force on the limiting block 13, the impact force sequentially passes through the limiting block 13, the retaining cylinder 12 and the movable plate 11 and acts on the fixing screw of the fixed movable plate 11, the fixing screw is easily loosened and cannot stably fix the movable plate 11, the rotation angle of the swing rod 7 in the rotation process cannot be accurately controlled, the threaded rod 16 abutting against the movable plate 11 is arranged in the embodiment, the impact on the movable plate 11 is buffered by the threaded rod 16, the situation that the swing rod 7 rotates to cause deviation due to looseness of the movable plate 11 in the use process is greatly reduced, and the limiting retaining effect of the limiting block 13 on the swing rod 7 is improved.
