Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically to a vertically flipping clamp displacement device. Background Technology

[0002] Robotic welding is commonly used in automotive chassis welding. During the welding process, the workpiece needs to be in the optimal welding position to achieve the desired welding effect. Therefore, the welding fixture needs to have a flipping function, so that the welding machine can weld the second side after the fixture flips the frame. However, existing flipping fixtures can only achieve flipping with a single clamp. After each welding, the machine needs to be stopped, the part removed, and then re-mounted for welding. Therefore, the welding efficiency is low, the welding robot has a long idle time, and it is not conducive to improving processing efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a vertical flipping fixture displacement device, which achieves edge flipping and two-station displacement, greatly shortening the part changeover time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vertically flipping clamp positioning device, characterized in that: it includes two opposing uprights, a flipping frame rotatably connected between the two uprights, two sets of transverse supports symmetrically arranged on both sides of the flipping frame, a turntable provided on the transverse supports, wherein a clamp bracket is detachably connected between the two turntables located on a set of opposing transverse supports, a first connecting positioning block is provided on the turntable, a second connecting positioning block is provided at the end of the clamp bracket, the first connecting positioning block is provided with a first V-tooth positioning block arranged transversely and two second V-tooth positioning blocks arranged longitudinally, hinge bolts are hinged to both ends of the first connecting positioning block, M-tooth positioning blocks corresponding to the first V-tooth positioning blocks and the second V-tooth positioning blocks are provided on the second connecting positioning blocks, and connecting grooves corresponding to the hinge bolts are provided at both ends of the second connecting positioning blocks.

[0006] Furthermore, the flipping frame has a baffle in the middle to separate the clamp supports on both sides.

[0007] Furthermore, the upright is provided with a first reduction motor that drives the tilting frame to tilt, and the transverse support is provided with a second reduction motor that drives the turntable to rotate.

[0008] Furthermore, the fixture support is provided with a fixture base plate, a fixture is arranged on one side of the fixture base plate, and a counterweight is arranged on the other side.

[0009] Furthermore, an end limit block is provided on the first connecting positioning block.

[0010] The advantages of this utility model include: the vertical flipping and repositioning method occupies little space, which can not only ensure that the fixture can be flipped independently, but also enable the switching of two sets of fixtures through the flipping and repositioning method, greatly improving the efficiency of parts changing and saving the waiting time for parts changing. The detachable connection can be used for quick replacement of multiple sets of fixtures. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0015] One such Figure 1-3 The vertically tilting clamp positioning device shown includes two opposing uprights 1, with a tilting frame 2 rotatably connected between them. A first reduction motor for driving the tilting frame 2 to tilt is mounted on each upright. The main body of the tilting frame is a rectangular frame structure, with two sets of transverse supports 3 symmetrically arranged on both sides of the tilting frame. The transverse supports 3 are located on the rotation axis of the tilting frame 2. A turntable 4 is rotatably mounted on each transverse support 3, and a second reduction motor for driving the turntable 4 to rotate is mounted on each transverse support 3. A clamp bracket 5 is detachably connected between the two turntables located on a set of opposing transverse supports 3. A clamp base plate 11 is mounted on the clamp bracket 5, with a clamp on one side of the clamp base plate 11 and a counterweight 12 on the other side to maintain the weight balance on both sides of the clamp bracket 5.

[0016] like Figure 2 As shown, the clamp bracket 5 in this embodiment is easy to disassemble and replace. A first connecting positioning block 6 is provided on the turntable 4, and a second connecting positioning block 7 is provided at the end of the clamp bracket 5. The first connecting positioning block 6 is provided with a first V-tooth positioning block 7 arranged laterally and two second V-tooth positioning blocks 8 arranged longitudinally. The two ends of the first connecting positioning block 6 are hinged to a hinge bolt 9. The second connecting positioning block 7 is provided with an M-tooth positioning block corresponding to the first V-tooth positioning block 7 and the second V-tooth positioning block 8. The two ends of the second connecting positioning block 7 have connecting grooves corresponding to the hinge bolt 9.
