[0039] Please see Figure 1-6 As shown, a frame machining fixing fixture includes:

[0040] A fixed base 1 is provided with a T-shaped slide rail 101 on its upper surface;

[0041] Bottom clamping assembly 2 is disposed on T-shaped slide rail 101 and slidably engaged with T-shaped slide rail 101. The bottom clamping assembly 2 is provided with a movable clamping part 3. The bottom clamping assembly 2 is used to clamp and fix the bottom of the frame body 5.

[0042] Side bar clamping assembly 4 is fixedly disposed on the upper surface of the fixed base 1. The side bar clamping assembly 4 is used to clamp and fix the side bars of the frame body 5.

[0043] The side rod clamping assembly 4 is provided with a movable clamping part 3.

[0044] Through the above technical solution, the bottom clamping component 2 and the side bar clamping component 4 can fix the frame body 5 of different shapes within a certain range. It is particularly suitable for clamping and fixing the tubular structure of the frame body 5. At the same time, a movable clamping part 3 is designed, which can not only clamp and fix the frame body 5, but also has a moving function. When grinding is required, it can be moved and adjusted to avoid interference.

[0045] The bottom clamping assembly 2 includes a support base 201, a connecting plate frame 202, a movable plate frame 203, an electric cylinder 204, and a movable adjustment unit. There are two support bases 201, and the bottom of each of the two support bases 201 is provided with a sliding groove that cooperates with the T-shaped slide rail 101. The support base 201 and the T-shaped slide rail 101 are in sliding cooperation.

[0046] Each of the two support bases 201 has a connecting plate frame 202 rotatably connected to its side wall. One end of each connecting plate frame 202 is rotatably connected to both ends of a movable plate frame 203. One end of an electric cylinder 204 is fixedly connected to the side wall of the movable plate frame 203, and the other end of the electric cylinder 204 is fixedly connected to the upper surface of the fixed base 1. Through this technical solution, the extension and retraction of the electric cylinder 204 can drive the movable plate frame 203 to move, thereby causing the connecting plate frame 202 to rotate angularly, and thus driving the support base 201 to move. Figure 2 From the perspective of the electric cylinder 204, when the electric cylinder 204 extends, it can drive the support base 201 to move to both sides; when the electric cylinder 204 retracts, it can drive the support base 201 to move inward.

[0047] The support base 201 has an internal cavity. Movable sliders 205 are slidably connected to both sides of the internal cavity of the support base 201. A clamping part 3 is slidably connected to the upper surface of the support base 201. The clamping part 3 is fixedly connected to the movable sliders 205. Through this technical solution, the movement of the movable sliders 205 can drive the clamping part 3 to move, thereby realizing the function of adjusting the position of the clamping part 3.

[0048] With this technical solution, when it is necessary to fix the frame body 5, the frame body 5 is set at the support seat 201. By moving the two support seats 201 in a centered manner, the clamping part 3 is driven to clamp and fix the bottom position of the workshop.

[0049] A threaded rod 206 is rotatably connected to the inner wall of the support base 201. The threaded rod 206 passes through the movable slider 205 and is threadedly engaged with the movable slider 205. A bevel gear A207 is fixedly connected to one end of the threaded rod 206. A servo motor 208 is fixedly connected to the inner cavity of the support base 201. A bevel gear B209 is fixedly connected to the end of the output shaft of the servo motor 208. The bevel gear B209 meshes with the bevel gear A207. Through this technical solution, The operation of the servo motor 208 can drive the bevel gear B209 to rotate, which in turn drives the bevel gear A207 to rotate. The rotation of the bevel gear A207 can drive the threaded rod 206 to rotate, which in turn drives the movable slider 205 to move, and then drives the clamping part 3 to move. Thus, it can clamp the frame and also has the function of movement adjustment. When grinding, the grinding position can be moved and adjusted, avoiding the phenomenon that the clamping tool blocks the grinding position or interferes with the grinding tool.

[0050] The side rod clamping assembly 4 includes a support frame 401, a rectangular rod 402, a movable seat 403, and an adjusting cylinder 404. The support frame 401 is fixedly mounted on the upper surface of the fixed base 1. The rectangular rod 402 is rotatably connected to the upper end of the support frame 401. The movable seat 403 is slidably connected to the side wall of the rectangular rod 402. Clamping parts 3 are slidably connected to both sides of the side wall of the movable seat 403.

[0051] A slider A407 is slidably connected in the inner cavity of the rectangular rod 402. One end of an electric push rod A408 is fixedly connected to the bottom end of the slider A407. The other end of the electric push rod A408 is fixedly connected to the bottom wall of the inner cavity of the rectangular rod 402. Through this technical solution, the slider A407 can be moved by the extension and retraction of the electric push rod A408, thereby moving the moving seat 403 and realizing the function of movement adjustment.

[0052] A connecting leg B406 is rotatably connected to the side wall of the rectangular rod 402. One end of the adjusting cylinder 404 is fixedly connected to the connecting leg B406, and a connecting leg A405 is rotatably connected to the other end of the adjusting cylinder 404. The connecting leg A405 is disposed on the upper surface of the fixed base 1 and is fixedly connected to the fixed base 1. The movable seat 403 has an inner cavity, and a slider B409 is slidably connected in the inner cavity of the movable seat 403. The slider B409 is fixedly connected to the clamping part 3. One end of an electric push rod B410 is fixedly connected to the inner cavity side wall of the movable seat 403, and the other end of the electric push rod B410 is fixedly connected to the side wall of the slider B409. Through this technical solution, the extension and retraction of the electric push rod B410 can drive the slider B409 to move, thereby driving the clamping part 3 to move. The movement of the clamping part 3 can clamp and fix the side rod position of the frame body 5. The angle of the rectangular rod 402 can be adjusted by adjusting the extension and retraction of the cylinder 404, thereby adapting to different models of frames.

[0053] The clamping part 3 includes a connecting base 301 and a limiting wheel 302. The limiting wheel 302 is rotatably connected to the upper end of the connecting base 301. An arc-shaped groove 303 is provided on the arc-shaped wall of the limiting wheel 302. Through this technical solution, the rod-shaped structure of the frame body 5 can be clamped by the clamping part 3.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
