Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a cylinder head oil injection hole processing and clamping device. Background Art

[0002] The cylinder head of a motorcycle engine needs to be machined with an injection groove at the tail of the cylinder liner, and then the oil is sprayed from the injection groove. When machining the injection groove, the cylinder head needs to be clamped first. The injection hole machining clamping devices on the market often have the problem of insufficient positioning accuracy. Due to the diverse geometric shapes of the cylinder head, traditional clamping devices are often difficult to accurately position, resulting in increased machining errors. At the same time, the lack of clamping force and stability has also become a key issue affecting the machining of the injection hole. In a high-speed machining environment, the clamping device is prone to instability, resulting in low efficiency of the production line. Therefore, it is necessary to design a cylinder head injection hole machining clamping device to achieve rapid clamping of the cylinder head injection hole. Utility Model Content

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a cylinder head oil injection hole processing clamping device, comprising:

[0024] A workbench 1, on which a spindle 2 is mounted; a tool on the spindle 2 is used to process the oil injection hole on the cylinder sleeve of the cylinder head;

[0025] A positioning assembly, the positioning assembly includes a positioning base plate 3, a positioning vertical plate 4 is fixed in the middle of the positioning base plate 3, a positioning circular hole 5 is opened on the positioning vertical plate 4, and a positioning mechanism is also fixed on the positioning vertical plate 4; wherein the positioning base plate 3 can be fixed on the sliding plate 15 of the linear guide rail, and when the sliding plate 15 moves, the positioning base plate is driven to move;

[0026] A tie assembly, the tie assembly comprising a tie cylinder 6, the cylinder rod of the tie cylinder 6 passes through the positioning circular hole 5, a rear pull disc 7 is fixed at the end of the cylinder rod, and the diameter of the rear pull disc 7 is smaller than the cylinder hole of the cylinder head 8;

[0027] A tie plate 13 is provided with a long slot hole 9, through which the tie plate can be connected to the cylinder rod of the cylinder.

[0028] The process of the utility model when in use is as follows: when the cylinder head 8 needs to be processed, the cylinder head 8 is positioned and connected to the positioning vertical plate 4. Specifically, the cylinder head 8 passes through the rear pull disc 7 through the cylinder hole thereon, and then the rear surface of the cylinder head 8 is abutted against the positioning vertical plate 4. During the abutment, the cylinder hole on the cylinder head 8 passes through the rear pull disc 7, and then the positioning is performed through the positioning mechanism and the positioning hole 14 on the cylinder head 8. After the positioning is completed, the tie disc 13 is connected to the cylinder rod of the tie cylinder 6. Specifically, the tie disc 13 is plugged and connected through the long slot hole 9 on the tie disc 13. It is connected to the cylinder rod of the tensioning cylinder 6, and then the tensioning cylinder 6 is started. The cylinder rod thereon retracts backwards, so that the rear tensioning disc 7 acts on the tensioning disc 13, and finally the tensioning disc 13 presses the cylinder head 8. After the cylinder head 8 is pressed, the main shaft 2 is started, and the main shaft 2 can move back and forth (the positioning base plate 3 can be connected to the sliding plate 15 on the linear guide rail, the main shaft 2 feeds, and the sliding plate 15 drives the positioning base plate 3 to move back and forth), and the oil injection hole 16 on the cylinder sleeve of the cylinder head 8 is processed. After the processing is completed, the cylinder rod of the tensioning cylinder 6 is loosened, and the cylinder head 8 can be taken out.

[0029] Further, the positioning mechanism includes a plurality of positioning pins 12 and a plurality of positioning columns 10. Specifically, the positioning mechanism of the utility model includes a plurality of positioning pins 12 and a plurality of positioning columns 10, and the cylinder head 8 can be quickly positioned by setting the positioning pins 12 and the positioning columns 10. Specifically, in order to better locate the position of the cylinder head 8, the front end of the positioning pin 12 of the positioning mechanism is also provided with a conical head, which can play a certain guiding role when positioning the cylinder head 8.

[0030] Furthermore, a bracket 11 is fixed on the positioning base plate 3, and the tie cylinder 6 is fixed on the bracket 11. Specifically, the utility model has a bracket 11 fixed on the positioning base plate 3, and the tie cylinder 6 can be fixed on the bracket 11.

[0031] Furthermore, the center hole on the cylinder rod of the tie cylinder 6 is concentrically arranged with the center hole of the positioning circular hole 5. The concentric arrangement ensures that the movement of the tie assembly is aligned with the center of the positioning assembly, which helps to maintain the stability of the clamping and avoid deviation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
