[0033] The application provides a cylinder head water jacket grinding device, and specifically comprises the following;

[0034] Reference can be made to Figure 1 The application mainly comprises a driving rod 1, a sealing shaft 2 arranged on the driving rod 1, an extension rod 3 detachably connected with the driving rod 1, an outer ring 4 fixedly connected to one end of the extension rod 3 away from the driving rod 1, a connecting shaft 5 fixedly connected with an inner cavity of the extension rod 3 and an elliptical friction shaft 6 detachably arranged on one end of the connecting shaft 5 away from the extension rod 3 through a sliding block 7, so that the cylinder head water jacket with a circular or elliptical inner cavity can be ground.

[0035] Reference can be made to Figures 1-2 The driving rod 1 is hollow, and one end of the driving rod 1 is connected with an external dust extractor through a pipeline; when the dust extractor starts to work, the grinding waste can be extracted.

[0036] Reference can be made to Figure 1 The driving rod 1 is provided with an anti-skid shaft 8, which can assist the driving rod 1 in rotating work; in order to prevent waste from running out from the top when the driving rod 1 works, the sealing shaft 2 that can be optionally rotated is arranged on the driving rod 1, the outlet can be tightly sealed through the sealing shaft 2, and the sealing shaft 2 is fixed, so that only the driving rod 1 located in the sealing shaft 2 can work.

[0037] Reference can be made to Figure 1 The extension rod 3 is detachably connected with the driving rod 1, and the length of the extension rod 3 is not limited; therefore, when the cylinder head water jacket with different depths is cleaned, the extension rod 3 with a more suitable length can be used.

[0038] Reference can be made to Figure 1The outer ring 4 of the extension rod 3 is arranged in the cylinder head water jacket, which reduces the left and right shaking during the grinding, reduces the contact area between the extension rod 3 and the cylinder head water jacket, thereby reducing the friction area and the resistance formed when the extension rod 3 rotates.

[0039] Further, the extension rod 3 is arranged in communication with the driving rod 1, and after the driving rod 1 is connected with the external dust extractor, the waste can enter the inner cavity of the two rods (the extension rod 3 and the driving rod 1) from the end of the extension rod 3 away from the driving rod 1.

[0040] Reference can be made to Figures 1-3 In order to arrange the friction shaft 6 at the end of the extension rod 3 away from the driving rod 1, but not to the requirement of absorbing the waste to the inner cavity for collection, the connecting shaft 5 is arranged to work, and the connecting shaft 5 is fixedly connected in the inner cavity of the end of the extension rod 3 away from the driving rod 1. After the connecting shaft 5 is connected with the inner cavity of the extension rod 3, there is a gap therebetween, so that the cylinder head water jacket grinding waste can enter the driving rod 1 from the bottom of the extension rod 3.

[0041] Reference can be made to Figures 1-3 In order to facilitate the replacement of the friction shaft 6, the sliding block 7 is arranged at one end of the connecting shaft 5, and the sliding block 7 is detachably connected with the connecting shaft 5. Thus, the disassembly and replacement of the friction shaft 6 are facilitated. Specifically, the sliding block 7 comprises a circular plate 71 and a square plate 72. The circular plate 71 is detachably connected with the connecting shaft 5 through bolts, and the square plate 72 is fixedly connected at the side of the circular plate 71 away from the connecting shaft 5. The square plate 72 is arranged in the friction shaft 6 and can reciprocate along the friction shaft 6, and will not rotate on the friction shaft 6. When the inner cavity of the cylinder head water jacket is in an elliptical shape, the friction shaft 6 rotates relatively with the rotation of the extension rod 3. During the rotation, based on the distance between the center of the friction shaft 6 and the edge of the inner cavity of the cylinder head water jacket, the friction causes the friction shaft 6 to move on the straight slide on the surface through the square plate 72, thereby realizing the effect of facilitating the grinding of the elliptical inner cavity. In addition, when the device grinds in a circular inner cavity, the distance to the friction shaft 6 is equal, so the relative movement of the friction shaft 6 will not be affected.

[0042] In the utility model, the working steps of the device are as follows:

[0043] 1. First, connect the driving rod 1 with the external dust extractor, and then stably arrange the sealing shaft 2 at the outlet end.

[0044] 2. Then, rotate the driving rod 1 under the condition that the sealing shaft 2 does not rotate, and at this time, the extension rod 3 rotates synchronously with the driving rod 1.

[0045] 3. Then, in the process of rotation, the extension rod 3 drives the friction shaft 6 to rotate synchronously through the connecting shaft 5, and the friction shaft 6 rotates to realize the grinding effect of the inner cavity of the cylinder head water jacket;

[0046] 4. Finally, through the work of the external dust extractor, the grinding waste can be extracted in the grinding process, avoiding subsequent impact.

[0047] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application. These changes and improvements are all within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
