[0031] Example 1

[0032] See also Figure 1-Figure 2 This embodiment provides a tooling for fixing castings, by using the movable splint to quickly approach the fixed splint along the slide groove, and the movable splint to slowly approach the fixed splint under the drive of the handle, so that the clamping operation of the casting using the fixed splint and the movable splint is easier.

[0033] In this embodiment, the tooling for fixing the casting includes a movable splint 30 that is slidably clamped on the base 10, the movable splint 30 is opposite to the fixed splint 20 on the base 10, a slider 32 is inserted into the movable splint 30, and a limit rod 33 is fixed to the slider 32 and clamped with the slide groove 12 formed on the base 10, and a handle 40 is rotatably connected to the movable splint 30, and the inner end of the handle 40 is threadedly connected to the slider 32. Rotating the handle 40 can drive the slider 32 to slide along the guide groove 13 obliquely arranged at the end of the slide groove 12.

[0034] In this embodiment, the movable splint 30 quickly approaches the fixed splint 20 by moving the slider 32 along the slide groove 12, and the slider 32 is driven to move along the guide groove 13 by rotating the handle 40, so that the movable splint 30 slowly moves toward the fixed splint 20 and clamps the casting, thereby improving the convenience of the casting clamping operation.

[0035] Specifically, the fixed splint 20 is vertically fixed to the left end of the base 10, and the fixed splint 20 and the base 10 are L-shaped as a whole. A mounting groove 11 for accommodating the movable splint 30 is opened on the base 10. The mounting groove 11 penetrates the opposite front and rear side walls of the base 10. The mounting groove 11 is configured as a rectangle as a whole. The mounting groove 11 extends along the longitudinal direction of the base 10 as a whole, that is, the fixed splint 20 is arranged vertically with the mounting groove 11 as a whole, and the slide groove 12 is formed at The top surface of the base 10, and the slide groove 12 extends along the longitudinal direction of the base 10, that is, the extension direction of the slide groove 12 is perpendicular to the fixed clamping plate 20, the slide groove 12 is symmetrically arranged on the base 10, and the guide groove 13 is formed at one end of the slide groove 12 close to the fixed clamping plate 20, and the left end of the guide groove 13 is inclined toward between the two slide grooves 12, the guide groove 13 is also connected with the mounting groove 11, and the guide groove 13 and the slide groove 12 are arranged above the mounting groove 11 as a whole.

[0036] In addition, the movable splint 30 is arranged parallel to the fixed splint 20 as a whole. The lower end of the movable splint 30 is provided with a clamping head 31 clamped with the mounting groove 11. The clamping head 31 can be slidably clamped inside the mounting groove 11 as a whole. The clamping head 31 is symmetrically arranged at the lower end of the movable splint 30. The rectangular block-shaped slider 32 can be slidably inserted into the end of the clamping head 31, and a cylindrical limiting rod 33 is fixedly connected to the slider 32. The limiting rod 33 is arranged vertically with the base 10. The limiting rod 33 extends to the top of the base 10 and can be slidably clamped inside the slide groove 12. At the same time, the limiting rod 33 can be smoothly moved into the guide groove 13 and can slide inside the guide groove 13.

[0037] In addition, the handle 40 is hinged on the movable splint 30 as a whole, and a pin 41 is fixed to the lower end of the handle 40. The pin 41 can be rotatably inserted into the inside of the clamp 31 and maintains a threaded connection with the slider 32 inside the clamp 31. When the handle 40 rotates with the pin 41 as the rotating axis, the clamp 31 and the slider 32 can be driven to slide along the axial direction of the pin 41 inside the clamp 31 by utilizing the clamping cooperation between the clamp 31 and the slider 32.

[0038] When in use, first place the casting on the right side of the fixed splint 20, and then quickly move the movable splint 30 toward the casting along the slide groove 12. When the limit rod 33 moves from the slide groove 12 into the guide groove 13, the handle 40 is rotated in the lower right direction, and the pin 41 will rotate synchronously with the handle 40 and drive the slider 32 to move toward the outside of the clamping head 31. By utilizing the sliding engagement between the limit rod 33 and the guide groove 13, the movable splint 30 can continue to move along the guide groove 13 toward the casting until the movable splint 30 clamps the casting. At this time, the self-locking effect formed by the threaded connection between the slider 32 and the pin 41 can be used to keep the position of the movable splint 30 stable, thereby achieving stable clamping of the casting.

[0039] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
