Description

Technical Field

[0001] The utility model belongs to the field of automobile parts processing equipment, and specifically relates to a novel automobile traction saddle inspection and welding integrated tooling. Background Art

[0002] The saddle is one of the important components of the automobile traction system. Most of the existing saddles are horseshoe-shaped, usually consisting of a main body and a bottom bracket. The I-shaped bracket is one of the common saddle brackets, which is mainly composed of a crossbeam and side panels connected to the two ends of the crossbeam. When processing the saddle, it is often necessary to weld the bracket first. Because the side panels are bent and special-shaped structures, the difficulty of fixing the side panels is increased. On the other hand, because the welding position of the crossbeam and the side panels is close to the large end of the side panels, during the operation, the two ends of the crossbeam need to be respectively opposite to the welding position of the side panels. If the operations are performed separately, the operation time will be relatively increased, and the separate operations will increase the error, resulting in difficulty in ensuring a good symmetrical posture of the two side panels, which will also directly affect the load capacity of the later saddle. In order to ensure the quality of the saddle, it is usually necessary to compare or measure the bending angles of the side panels before welding to ensure that the structural dimensions of the side panels on both sides are basically consistent.

[0003] For this purpose, the applicant filed a patent application with patent number CN202320796028.5 and the name of "Automobile Traction Saddle Inspection and Welding Tooling" in the early stage. However, the applicant found in the subsequent continuous use that the weld inclination angle between the crossbeam and the side panel was 90°, so the operation was vertical welding, which was more laborious than flat welding, and the technical requirements for welders were also higher, which was not conducive to the promotion and use of the device. Utility Model Content

[0004] In view of this, the utility model provides a novel integrated inspection and welding tool for automobile traction saddles to solve the problems in the prior art that the welding of I-shaped saddles needs to be inspected separately, the positioning tool has poor reliability, the welding technology requirements are high, and the welding efficiency is slow.

[0005] The technical solution is as follows:

[0006] A novel integrated inspection and welding tool for automobile traction saddle, wherein the saddle comprises a crossbeam and side plates connected to both ends of the crossbeam, the side of the side plate away from the crossbeam has an inner groove, and the width of one end of the side plate is greater than the width of the other end. The key is that the tool comprises a frame and a workbench rotatably supported on the frame, and the frame has a driving mechanism for driving the workbench to flip;

[0007] The workbench is provided with a base, and the two sides of the base are provided with symmetrically arranged detection plates and side plate abutment components, the side contour of the base and the end contour of the detection plate are respectively adapted to the inner and outer side contours of the side plate, and the vertical distance between the end of the detection plate and the opposite side of the base is adapted to the thickness of the side plate;

[0008] The base is provided with a beam placement seat, which has a placement groove which is open at the top and both sides, the width of the placement groove is adapted to the thickness of the beam, and the side plate pressing assembly is used to press the side plate against the base.

[0009] By adopting the above scheme, there is actually enough gap between the inspection plate and the base for the side panel to pass through. In this way, when putting it in for welding, if its own size or structure is not up to standard, it cannot be put into the gap between the two to complete the inspection of the component. If it can be put in, it proves that the component is qualified, and the side panel abutment assembly can be used to tighten the side panel and the two ends of the beam to carry out the lower welding operation.

[0013] As a preferred embodiment: a hand wheel is provided at one end of the frame opposite to the flipping mechanism, the hand wheel is fixedly connected to the corresponding support seat, and a locking structure that cooperates with the frame is provided.

The above scheme has a simple structure, low cost, and convenient operation and implementation.

[0015] As a preference: the bottom of the locking block has a convex column, and the inner and / or outer slots have a socket adapted to the convex column. With the above solution, the axial direction of the locking block can be limited to prevent it from falling off, thereby improving the locking reliability.

[0016] Preferably, the side panel abutting assembly includes a horizontally arranged abutting cylinder, the piston rod of which is arranged opposite to the side of the base and connected to a abutting flat head, the abutting flat head having a abutting plane that can fit with the side panel. By adopting the above scheme, the force stability of the side panel can be improved by using the contact and abutment between the plane and the side panel.

[0017] Preferably, the side plate has an axial hole, and the abutting flat head has a positioning round head adapted to the axial hole, and the end of the positioning round head is conical. With the above solution, the side plate can be further positioned by inserting the positioning round head into the axial hole, and the positioning round head can perform a secondary inspection on the side plate to ensure that the axial holes on the two side plates are arranged facing each other.

With the above solution, modular assembly and disassembly of the side plate abutting assembly can be realized through the side stand, and the moving stability of the abutting flat head can be ensured through the guiding structure.

[0019] Preferably, a lever cylinder is provided on one side of the beam placement seat at the top of the base, the lever length direction of the lever cylinder is perpendicular to the length direction of the placement slot, and when the beam is placed in the placement slot, the lever cylinder is used to press the upper side of the beam.

[0033] A beam placement seat 40 is provided on the top of the base 4. The beam placement seat 40 has a placement groove 400 which is open on the top and both sides. The width of the placement groove 400 is adapted to the thickness of the beam 1. The side panel clamping assembly 6 is used to clamp the side panel 2 and the base 4.

[0034] As shown in the figure, the frame 9 in the present application is generally U-shaped, including a base plate 97, and support plates 98 symmetrically arranged at both ends of the base plate 97.

If it cannot be inserted or is difficult to insert, it can be judged that the side panel 2 does not meet the design standards and should be replaced or repaired.

[0047] If the quality of the side panel 2 is correct and the cross beam 1 and the side panel 2 are in place, the lower end of the side panel 2 is actually supported on the top of the lifting plate 80. The height of the side panel 2 can be adjusted as needed to adjust the contact height with the cross beam 1, that is, to achieve the height adjustment of the welding position. After the adjustment is completed, the piston rod of the tightening cylinder 60 is extended, and the side panel 2 is pressed against the base 4 with the tightening flat head 61 and the positioning round head 62. The support seat 90 is driven to rotate by the power mechanism 92. At this time, the workbench 3 is in a horizontal forward posture, and the vertical welding is changed to flat welding. Then the welding operation can be carried out. After the welding is completed, the workbench 3 is reset to an upward posture, the piston rod of the tightening cylinder 60 is retracted, and then the lifting plate 80 is lifted up by the lifting cylinder 81 to eject the welded saddle.
