[0001] This utility model mainly relates to a holding clamp. [Background Technology]

[0002] During machining, the workpiece is subjected to external forces such as cutting force, centrifugal force, and inertial force. In order to ensure that the workpiece can still maintain the machining position determined by the positioning elements in the fixture under these external forces, without vibration or displacement, and to reliably guarantee the machining quality of the workpiece, improve machining efficiency, reduce labor intensity, and fully utilize and expand the process performance of the machine tool, the selection of the positioning, clamping position, and clamping force of the tooling fixture is particularly important.

[0003] In the existing technology, common fixtures are usually clamped from above the workpiece. Such fixtures are quite common, have a simple structure, and are relatively easy to manufacture. Moreover, current fixtures are generally set up individually, which is sufficient to meet the processing requirements when dealing with a large number of products. [Utility Model Content]

[0006] The clamping module includes a lifting cylinder and a clamping block. The lifting cylinder is installed on the ground of the clamping seat, and the piston rod of the lifting cylinder passes through the top surface of the clamping seat and connects to the clamping seat. The front end of the clamping seat extends horizontally to the clamping groove so as to press the workpiece in the clamping groove through the front end of the clamping seat.

[0007] The front end of the clamp is provided with a cavity, the bottom end of the cavity is open, a shaft is provided inside the cavity, and a pressure block is hinged to the shaft. The pressure block is located above the clamping groove, and the thickness of the first end of the pressure block is greater than the thickness of the last end.

[0008] Preferably, the clamping slot extends laterally through the clamping seat.

[0009] Preferably, silicone blocks are adhered to both the first and last ends of the pressing block, and the silicone block at the first end is thicker than the silicone block at the last end.

[0015] The beneficial effects of this utility model compared with the prior art are:

[0016] In this design, a lifting cylinder pushes the first and second clamping blocks upwards, then inserts the workpiece into the clamping groove. The second clamping block moves downwards and abuts against the protrusion to press the workpiece firmly. The first clamping block moves downwards, and the head end of the pressure block contacts the stop edge, pushing the pressure block to deflect and press the workpiece. The higher the stop edge, the tighter the pressure, adapting to different sizes of this type of machined workpiece. The workpiece is securely fixed in the clamping groove by the cooperation of the first and second clamping blocks. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]
