[0002] A welding workbench is a workbench designed for welding small workpieces. Its surface usually has mounting holes for mounting different types of processing devices.

[0003] Currently, during welding operations, fixtures are typically assembled onto the welding workbench as needed. However, in actual use, traditional fixtures are mostly single screw components combined with clamping blocks, which can only achieve a single clamping function and cannot be rotated at a certain angle, resulting in limited processing operations and compromised processing efficiency. Therefore, there is an urgent need for a rotating fixture for the welding equipment workbench. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flipping fixture for a welding equipment workbench.

[0007] A second lead screw is screwed to one side of the middle of the turntable. One end of the second lead screw extends to one side of the outer wall of the mounting plate. A locking plate is provided on the outer wall of the mounting plate. Multiple locking slots are arranged in a circular array on the locking plate. The locking slots are engaged with one end of the second lead screw.

[0008] Furthermore, in a preferred configuration, the locking groove opening gradually narrows inward.

[0010] Furthermore, in a preferred configuration, a connecting pin is rotatably mounted at one end of the lead screw, and one end of the connecting pin is rotatably connected to the clamping block.

[0011] In addition, a preferred structure is that a rubber pad is installed on one side of the outer wall of the mounting plate, one side of the rubber pad is in pressure contact with the outer wall of the fixing plate, and when the fixing plate rotates by the turntable, the rubber pad is in frictional contact with the outer wall of the fixing plate.

[0012] Furthermore, in a preferred configuration, the first fixing plate and the second fixing plate are installed symmetrically from left to right, and the first fixing plate and the second fixing plate are connected by a guide rod. A clamping block is slidably installed on the upper limit of the guide rod. One end of the clamping block is connected to the first lead screw by a connecting pin, and the clamping block moves horizontally synchronously as the first lead screw rotates.

[0013] In addition, a preferred structure is that one end of the fixing plate two is rotatably mounted on the mounting plate two, and the mounting plate two and the mounting plate one are assembled together on the worktable.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a turntable and a hollow shaft synchronously drive the fixed plate assembly to rotate, thereby changing the overall angle of the workpiece to meet processing requirements. At the same time, during the rotation adjustment process, the lead screw on the turntable is rotated to cooperate with the locking plate to achieve the function of free locking, thus satisfying the convenience of adjustment and improving processing efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A flipping fixture for a welding equipment workbench includes a mounting plate 1, a hollow shaft 10 is rotatably mounted in the middle of the mounting plate 1, a turntable 5 and a fixing plate 6 are fixedly connected to both ends of the hollow shaft 10 respectively, and the bottom of one end of the fixing plate 6 is connected to the fixing plate 9 through a guide rod 8, and a clamping block 7 is slidably mounted at the upper limit of the guide rod 8.

[0023] Furthermore, a lead screw 4 is screwed to one side of the middle part of the turntable 5. One end of the lead screw 4 extends to one side of the outer wall of the mounting plate 1. A locking plate 12 is provided on the outer wall of the mounting plate 1. Multiple locking grooves 121 are arranged in a ring array on the locking plate 12. The locking grooves 121 are engaged with one end of the lead screw 4.

[0024] Furthermore, the opening of the locking groove 121 gradually narrows inward, which can improve the stability when the lead screw part 4 is engaged with the locking groove 121.

[0025] Furthermore, a lead screw 3 is screwed to the middle of the hollow shaft 10. One end of the lead screw 3 extends outward and is screwed to the middle of the turntable 5, and the other end of the lead screw 3 extends outward and is screwed to the middle of the fixed plate 6.

[0026] Furthermore, a connecting pin 31 is rotatably mounted on one end of the lead screw component 3, and one end of the connecting pin 31 is rotatably connected to the clamping block 7.

[0027] Furthermore, a rubber pad 11 is installed on one side of the outer wall of the mounting plate 1. One side of the rubber pad 11 is pressed against the outer wall of the fixing plate 6, and when the fixing plate 6 rotates through the turntable 5, the rubber pad 11 is in frictional contact with the outer wall of the fixing plate 6.

[0028] Furthermore, the first fixing plate 6 and the second fixing plate 9 are installed symmetrically from left to right, and the first fixing plate 6 and the second fixing plate 9 are connected by a guide rod 8. A clamping block 7 is slidably installed on the upper limit of the guide rod 8. One end of the clamping block 7 is connected to the lead screw 3 by a connecting pin 31, and the clamping block 7 moves horizontally synchronously as the lead screw 3 rotates.

[0029] Furthermore, one end of the fixing plate 29 is rotatably mounted on the mounting plate 22, and the mounting plate 22 and the mounting plate 1 are assembled together on the workbench.

[0030] In this embodiment, the first lead screw 3 is rotated to drive the clamping block 7 to perform horizontal displacement and clamp and lock the workpiece to be processed. After the clamping is stable, when it is necessary to flip it, the second lead screw 4 provided on the turntable 5 is released, so that the second lead screw 4 rotates to disengage from the locking plate 12 provided on the outside of the mounting plate 1. The locking plate 12 has a locking groove 121 for engaging the second lead screw 4. Then, the turntable 5 is rotated to synchronously drive the first fixing plate 6, the clamping block 7, the guide rod 8, and the second fixing plate 9 to rotate. After the rotation is completed, the second lead screw 4 is locked into the locking groove 121. At this time, the rotation function is restricted, but the clamping block 7 can still be adjusted by rotating the first lead screw 3.

[0031] In actual use, the fixture is installed onto the workbench by mounting plate 1 and mounting plate 2.

[0032] In actual use, the hollow shaft 10 has a thread inside to connect to the screw rod 3.

[0033] In actual use, the rubber pad 11 and the clamping block 7 make frictional contact to generate damping force, thereby improving the smoothness and stability of the rotation process.

[0034] In this utility model, the turntable 5, together with the hollow shaft 10, synchronously drives the fixed plate assembly to rotate, thereby changing the overall angle of the workpiece to meet the processing requirements. At the same time, during the rotation adjustment process, the lead screw 4 set on the turntable 5 is rotated to cooperate with the locking plate 12 to achieve the function of free locking, thus satisfying the convenience of adjustment and improving processing efficiency.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
