[0017] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] like Figure 1-3As shown, the trimming device for cylinder head processing of this embodiment comprises a base 1 and a bracket 5 arranged on the base 1, the bracket 5 is provided with a horizontally movable slide 6 and a driving member (a cylinder is selected), the slide 6 is used to carry a raise-lowerable grinding mechanism, the base 1 is provided with a rotatable permanent magnetic chuck 2, the bracket 5 is provided with a laser distance sensor 11 (preferably ecotterlsd-250), the permanent magnetic chuck 2 is used to fix the cylinder head and drive the cylinder head to rotate, and the laser distance sensor 11 is used to detect the distance of the laser irradiated to the outer wall of the cylinder head along the horizontal path during the rotation of the cylinder head;

[0020] The grinding mechanism includes a grinding head 9 with a cylindrical structure. The grinding head 9 and the central axis of the permanent magnetic chuck 2 and the laser line of the laser ranging sensor 11 are all located in the same vertical plane. A controller (preferably KV Nano series) is also provided on the bracket 5. The output end of the laser ranging sensor 11 is connected to the input end of the controller, and the output end of the controller is connected to the driving part of the slide 6.

[0021] The slide seat 6 is provided with a lifting frame 7, a screw rod 8 for controlling the lifting of the lifting frame 7, and a driving member (a motor is selected) for driving the screw rod 8 to rotate. The grinding mechanism is arranged at the bottom end of the lifting frame 7.

[0022] The grinding mechanism also includes a support 10 for carrying a grinding head 9 and its driving member (a motor is selected). The grinding head 9 is arranged at one end of the support 10 and the other end of the support 10 is rotationally connected to the bottom end of the lifting frame 7 through a torsion spring.

[0023] A gear ring 3 is provided below the permanent magnetic chuck 2, and the gear ring 3 rotates with the base 1. The base 1 is provided with a driving gear 4 meshing with the gear ring 3 and a driving member (a motor is selected).

[0024] The controller is also used to control the laser distance measuring sensor 11, the permanent magnetic chuck 2 and the switches of all driving parts.

[0025] When processing the cylinder head, the edge of the cylinder head to be polished is placed upward on the permanent magnetic chuck 2. After the permanent magnetic chuck 2 is turned on, the cylinder head is fixed, and then the lifting frame 7 is adjusted to rise and fall and the slide seat 6 is adjusted to translate until the polishing head 9 fits the cylinder head. Then, the motor corresponding to the polishing head 9 and the driving gear 4 is turned on to polish and trim the cylinder head. During the polishing process, the rectangular cylinder head rotates continuously, and the polished point of the cylinder head is always the part with the shortest horizontal distance between the edge of the cylinder head to be polished and the laser ranging sensor 11. The polishing mechanism can move horizontally to reach any position. The position of the grinding point, and in the process of trimming the cylinder head, the position of the grinding point on the cylinder head changes continuously. Therefore, after the controller receives the ranging signal output by the laser ranging sensor 11, it can control the operation of the motor corresponding to the slide 6 according to the ranging signal, thereby controlling the overall translation formed by the slide 6, the lifting frame 7 and the grinding mechanism and controlling the translation distance, thereby allowing the grinding head 9 to move with the grinding point of the cylinder head, so that the grinding head 9 can always fit the cylinder head from the outside, thereby achieving the effect of continuous grinding and trimming of the cylinder head.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
