Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an adaptive tooling clamp. Background Art

[0002] Batch-processed workpieces inevitably have certain differences, such as slight deviations in the vertical angle, rotation angle, center offset, etc. of each welding part. The existing fixtures and jigs are designed to prevent the workpiece from moving. During processing, the workpiece is directly fastened to the jig, and the workpiece cannot be shaken at all. If the workpiece is processed on such a fixture (such as welding other parts), if the processing part of the workpiece has a slight deviation, the processed workpiece will become waste.

[0003] In an adaptive tooling fixture with the public specification of Chinese utility model patent application CN208005056U, although it has the advantages of simple structure, can be adjusted according to the accuracy of the workpiece, and greatly reduces the scrap rate, it is not convenient to repair and replace the fixture in the later stage, the later cost is high, and it is not suitable for clamping parts of various shapes and densities. For this reason, an adaptive tooling fixture is proposed. Utility Model Content

[0007] Preferably, the transmission mechanism comprises a first gear and a second gear, the first gear is movably provided at the bottom end of one side of the lifting slot through a rotating shaft, and a second gear meshing with the first gear is provided at one side of the first gear;

[0008] Preferably, the clamping mechanism comprises a connecting rod, a fixed wheel and a movable wheel, both ends of the frame are provided with connecting rods movably through a rotating shaft, the top end of the connecting rod is provided with a fixed wheel movably through a rotating shaft, and the bottom end of the connecting rod is provided with a movable wheel movably through a rotating shaft;

[0009] Preferably, the fixing mechanism comprises a screw, a fixing block and a limiting rod, the screw is movably arranged inside the threaded groove through a rotating shaft, the threads at both ends of the screw are arranged oppositely, fixing blocks are movably arranged on the outer sides of both ends of the screw through threaded holes, a limiting rod is fixedly arranged above the screw inside the threaded groove, and the limiting rod is movably connected to the fixing block through a mounting hole;

[0010] Preferably, a first handle is fixedly provided on the outer side of the frame at one end of the first gear shaft;

[0011] Preferably, a second handle is fixedly provided on the outer side of the frame at one end of the screw shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This is an adaptive tooling fixture. When using this device, the parts to be clamped are placed on the auxiliary wheels, and the first handle is turned to rotate the first gear connected to it. The rotation of the first gear drives the second gear meshing with it to rotate. The rotation of the second gear causes the lifting column connected to its fixed block at its top to rise. The rising of the threaded column drives the trapezoidal block fixedly connected to it to rise. The rising of the trapezoidal block drives the movable wheel at the bottom of the connecting rod movably connected to the frame at both ends through the rotating shaft to move along the inclined surface of the trapezoidal block, so that the fixed wheel at its top fixes the parts to be clamped. This setting can be adjusted to adapt to the fixing of parts of different shapes and diameters, thereby enhancing the applicability of the device, and the firm fixation enhances the stability of the device.

[0014] This is an adaptive tooling fixture. The fixture will be damaged during long-term and extensive use and needs to be repaired or replaced to ensure the device is in good condition. The second handle is turned to rotate the screw rod connected to it for transmission. Since the threads at both ends of the screw rod are arranged in opposite directions, the rotation of the screw rod drives the fixed blocks at both ends of the screw rod to move in opposite directions through the threaded holes. Therefore, the fixed blocks leave the fixed grooves, which makes it convenient to repair and replace the device, thereby enhancing the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
