Description

Technical Field

[0001] The utility model belongs to the technical field of grinding fixtures, and in particular relates to a fixture used for grinding. Background Art

[0002] In the field of mechanical processing, it is often necessary to clamp and fix workpieces such as steel plates and steel materials, and perform various mechanical treatments on them. Some parts of some workpieces need to be mechanically ground to make their surfaces smoother. Therefore, it is necessary to use a fixture to fix the workpiece first, and then use a grinding machine to grind it.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: However, the current grinding fixtures can usually only use two or more chucks to clamp and fix the two sides of the workpiece, but cannot change the angle of the chuck, which makes it inconvenient to fix some workpieces of special shapes, reducing the scope of application.

[0004] To this end, we propose a clamp for grinding to solve the above problems. Utility Model Content

Telescopic rods are respectively connected to the bottom of the two cylinders, and extension blocks are respectively welded to the bottoms of the two telescopic rods, and inverted U-shaped racks are welded to the bottom walls of the two extension blocks, wherein movable motors are horizontally installed on the two racks, and the output shafts of the two movable motors are coaxially connected with inner support shafts respectively, and the clamping mechanism includes flip blocks respectively fixedly mounted on the two inner support shafts and chucks respectively welded under the two flip blocks, and the two chucks are brought close to each other to clamp and fix the workpiece therebetween. The type of the workpiece is a mechanical component during mechanical processing, such as steel plates, steel materials, etc. The shape of the chuck is determined according to the actual situation and is not necessarily based on the attached drawings. The fixed motor and the movable motor require external power supply.

[0009] As a preferred embodiment, the screw and the slide rod are both arranged horizontally, and both sides of the screw are rotatably connected to the upper platen, so that the fixed motor can drive the screw to operate stably when it is running.

[0010] As a preferred embodiment, mounting grooves are formed on the two fixing tubes, and the two cylinders are respectively mounted on the bottom walls of the two mounting grooves, so that the structure of the mounting grooves remains stable.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The fixture for grinding drives the screw rod to operate by driving the fixed motor to move the two chucks closer to each other. The height and angle of the chucks can be adjusted by cooperating with the operation of the two cylinders and the two movable motors, thereby adapting to the fixation of various workpieces of different shapes and the subsequent grinding work, and improving the application scope of the fixture.

[0016] The clamp used for grinding first operates a fixed motor to drive two clamps to approach each other, then operates two cylinders to drive two telescopic rods to extend or contract, and the two extending blocks drive the clamps thereunder to rise and fall. Two movable motors can also be used to operate to drive two inner support shafts, two flip blocks and two clamps to flip, thereby changing the height and angle of the clamps to facilitate the fixation of workpieces of different shapes.
