[0024] The utility model provides the following technical solutions:

[0025] Embodiment 1

[0026] Combination Figures 1 to 4 A fixture suitable for finishing of a cylinder head comprises a base plate 1, a disassembly mechanism 3 is arranged on the top of the base plate 1, a connection box 2 is arranged on the top of the disassembly mechanism 3, and a clamping mechanism 4 is arranged inside the connection box 2;

[0027] The disassembly and assembly mechanism 3 includes a long groove 31, which is fixedly connected to the top of the base plate 1, a long block 32 is fixedly connected to one side of the long groove 31, a connecting plate 33 is fixedly connected to the side of the long block 32 away from the long groove 31, a threaded rod 34 is rotatably connected inside the connecting plate 33, a movable plate 35 is threadedly connected to the outer wall of the threaded rod 34, a clamping block 36 is fixedly connected to one side of the movable plate 35, and an inserting block 37 is fixedly connected to the bottom of the connection box 2.

[0028] Furthermore, the outer shape of the insert block 37 matches the inner wall shape of the long slot 31 , and the insert block 37 is plugged into the inner wall of the long slot 31 , thereby achieving the purpose of stable limiting.

[0029] Furthermore, a through opening is formed on one side of the long slot 31 , and a socket is formed on one side of the inserting block 37 . The clamping block 36 passes through the through opening, and the clamping block 36 is inserted into the inner wall of the socket, so that the inserting block 37 can be stably positioned.

[0030] Furthermore, a sliding opening is provided inside the movable plate 35 , and the movable plate 35 is slidably connected to the outer side of the long block 32 , so that the movable plate 35 can move stably.

[0031] Furthermore, the threaded rod 34 is rotatably connected to the outside of the long slot 31 , and one end of the threaded rod 34 away from the long slot 31 is fixedly connected to a hand wheel, so that the threaded rod 34 can be rotated by shaking the hand wheel.

[0032] Embodiment 2

[0033] See also Figures 1 to 4 On the basis of the first embodiment, the clamping mechanism 4 further comprises an electric push rod 41, which is fixedly connected to the inner wall of the connecting box 2, and one end of the electric push rod 41 away from the inner wall of the connecting box 2 is fixedly connected to a slide plate 42, and a short shaft 43 is fixedly connected to the top of the slide plate 42, and a clamping plate 44 is fixedly connected to the top of the short shaft 43, so that the cylinder head can be stably clamped.

[0034] Furthermore, the slide plate 42 is slidably connected to the inner wall of the connection box 2 , a slot is provided on the top of the connection box 2 , and the short shaft 43 passes through the slot, so that the short shaft 43 can move through the slot.

[0035] In actual operation, when this device is used, the staff can first install the base plate 1 at a suitable position for cylinder head finishing through the installation hole opened in the base plate 1, and then place the cylinder head that needs to be finished on the top of the connecting box 2, and then start the electric push rod 41 to make the electric push rod 41 drive the slide plate 42 to move, and the slide plate 42 drives the clamping plate 44 to move to a position close to the cylinder head through the short shaft 43, so that the cylinder head can be stably clamped and limited under the action of the clamping plate 44, thereby ensuring the stability of the cylinder head during the finishing process and improving the accuracy of the cylinder head during the finishing process.

[0036] Then, when the device needs to be disassembled for inspection and maintenance during long-term use, the hand wheel can be first turned to drive the threaded rod 34 to rotate. Since the threaded rod 34 and the movable plate 35 are threadedly connected, the rotational movement of the threaded rod 34 is converted into a linear movement of the movable plate 35. At the same time, the movable plate 35 can slide and limit on the outside of the long block 32, thereby ensuring stability during the movement, so that the movable plate 35 can drive the card block 36 to disengage from the inside of the plug block 37, canceling the limit on the plug block 37, and then the plug block 37 can be pulled out from the inside of the long groove 31 through the connecting box 2, so that the overall disassembly and assembly of the connecting box 2 can be realized. While realizing the clamping and positioning of the cylinder head, it can also achieve good disassembly and maintenance efficiency, further improving the convenience of the device during operation, and reducing the time spent by the staff during the disassembly and assembly process.
