[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0032] An end face clamping device for boring the inner hole of an engine cylinder block mainly consists of a first clamping body 1 and an end face clamping mechanism 13 that cooperates with it.

[0033] The first clamping body 1, as an important part of the device, has a first chamber 2 opened at its center. On the side wall of the first clamping body 1, a first air inlet 3 and a first air outlet 4 are respectively opened. A first piston disc 5 is fixedly arranged in the first chamber 2, and this piston disc effectively separates the first air inlet 3 and the first air outlet 4. One end of the first piston disc 5 is firmly fixedly provided with a first piston rod 6. One end of the first piston rod 6 penetrates through the end face of the first clamping body 1, and a conical top block 7 is fixedly arranged at this end. On the first clamping body 1, a number of adjusting blocks 8 are slidably arranged. A number of inclined first sliding grooves 9 are opened along the generatrix direction of the conical top block 7. A first sliding block 10 is slidably arranged in the first sliding groove 9, and the first sliding block 10 is fixedly arranged on the adjusting block 8. A clamping rod 11 is also slidably arranged on the adjusting block 8. One end of the clamping rod 11 is fixedly provided with a clamping block 12. The clamping rod 11 mainly clamps the side wall of the cylinder block, and the clamping block 12 clamps the end face of the cylinder block.

[0034] When liquid is filled into the first air inlet 3, the pressure of the liquid will push the first piston disc 5 to move. The first piston disc 5 then drives the first piston rod 6 and the conical top block 7 to move. Since the first sliding grooves 9 on the conical top block 7 cooperate with the first sliding blocks 10 on the adjusting blocks 8, when the conical top block 7 moves, it will drive a number of adjusting blocks 8 to move towards the center of the first clamping body 1 through the first sliding grooves 9 and the first sliding blocks 10, thereby realizing the stable clamping of the side wall of the cylinder block.

[0035] An end face clamping mechanism 13 is fixedly arranged on one side of the first clamping body 1. This end face clamping mechanism 13 mainly includes a second clamping body 14 fixedly arranged on one side of the first clamping body 1. A second chamber 15 is opened at the center of the second clamping body 14, and a second air inlet 16 and a second air outlet 17 are opened on its side wall. A second piston disc 18 is fixedly arranged in the second chamber 15, and the second piston disc 18 separates the second air inlet 16 and the second air outlet 17. One end of the second piston disc 18 is fixedly provided with a second piston rod 19. One end of the second piston rod 19 penetrates through the end face of the second clamping body 14 and is fixedly provided with a number of second sliding grooves 20. A second sliding block 21 is fixedly arranged in the second sliding grooves 20. One end of the clamping rod 11 is fixedly connected to the second sliding block 21.

[0036] When liquid is filled into the second air inlet 16, the liquid pushes the second piston disc 18 to move. The second piston disc 18 drives the second piston rod 19 and a number of second sliding grooves 20 to move. Since the second sliding block 21 is fixedly connected to one end of the clamping rod 11, the movement of the second sliding grooves 20 will drive the clamping rod 11 to slide in the adjusting block 8, thereby realizing the clamping of the end face of the cylinder block.

[0037] In order to make the movement of the adjusting block 8 more stable, a number of I-shaped slideways 22 are provided on the first clamping body 1. An I-shaped slider 23 is slidably arranged in the I-shaped slideway 22, and the adjusting block 8 is fixedly arranged on the I-shaped slider 23.

[0038] In order to improve the service life of the clamping block 12, a wear-resistant piece 24 is fixedly arranged at one end of the clamping block 12.

[0039] In order to ensure the sealing performance of the piston, piston sealing rings 25 are fixedly arranged on both the first piston disc 5 and the second piston disc 18.

[0040] In order to prevent dust from entering the interior of the clamping body, dust-proof rings 26 are fixedly arranged on both the first clamping body 1 and the second clamping body 14.

[0041] At the same time, detachable sealing end caps 27 are arranged on both the first clamping body 1 and the second clamping body 14, which is convenient for maintaining and overhauling the internal components.

[0042] In addition, a protective plate 28 is fixedly arranged on the first clamping body 1. The protective plate 28 is arranged above the conical top block 7, which plays a role in protecting the conical top block 7 and preventing foreign objects from entering.

[0043] Working principle: During the use of the present invention, first, liquid is filled into the first air inlet 3. The liquid pushes the first piston disc 5 to move, and then drives the first piston rod 6 and the conical top block 7 to move. The conical top block 7, through the first chute 9 and the first slider 10 thereon, pushes a number of adjusting blocks 8 to move towards the center of the first clamping body 1, so as to clamp the side walls of cylinders with different diameters.

[0044] Then, the end face clamping mechanism 13 works. Liquid is filled into the second air inlet 16, which pushes the second piston disc 18 to move, and then drives the second piston rod 19 and the second slideway 20 to move. The second slideway 20 drives the clamping rod 11 to slide in the adjusting block 8, so as to clamp the end face of the cylinder. In this way, the inner hole end face of the cylinder is tightly clamped, which is convenient for subsequent boring processing.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
