[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, the casting needs to be processed to obtain an object with a certain shape, size and performance.

[0003] The counterweight castings cast by casting need to go through steps such as tooling and drilling jigs in the subsequent processing, design and production. The tooling and drilling jigs need to be fixed and tightened when in use. The commonly used fixing structure is the use of screws, nuts, pressure plates, and support rods that cooperate with each other for fixing. However, during the clamping process, the pressure plate is moved from the bottom to the top, which is a long distance, and the screw is exposed to the outside, which makes it easy to collide during the clamping process, causing damage to the screw threads, making it difficult to operate during subsequent clamping and fixing. Utility Model Content

[0008] As an improvement of the above technical solution, the bracket is arranged in the middle of the base away from the supporting mechanism, a notch is opened on the side of the upper end of the bracket corresponding to the supporting mechanism, and a screw is placed inside the notch for fixing.

[0009] As an improvement of the above technical solution, the support mechanism includes a limit frame, a first reinforcement member is connected to one side of the limit frame, a second reinforcement member is arranged at the lower end of the other side of the limit frame, and a rubber support pad is also arranged on the surface of the limit frame corresponding to the limit clamping mechanism.

[0010] As an improvement of the above technical solution, a casting is placed on one side of the limiting frame corresponding to the limiting and clamping mechanism, and is fixed by crimping with a pressing plate.

[0011] As an improvement of the above technical solution, a support column is further provided at the upper end of the base, and at least two groups of support columns are provided and placed at the lower end of the casting.

[0012] Beneficial effects of the utility model:

[0013] By using a screw rod to connect the pressure plate at the upper end of the bracket and locking and adjusting it with a nut, free adjustment can be made when pressing and locking castings of different heights, thereby improving the efficiency of adjustment. In addition, by providing adjustment holes through the surface of the pressure plate, it can be freely adjusted when pressing castings of different sizes, so that one end of the pressure plate can be pressed and fixed on the surface according to the size of the casting, thereby improving the efficiency of pressing and locking.
