[0045] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides a cylinder inner hole processing positioning tool, including a cylinder housing 1, a base plate 2, a clamping plate 3 and a pressure block 4, and also includes: an adjusting device 5, which is fixedly mounted on the base plate 2; wherein the clamping plate 3 is movably connected to the adjusting device 5.

[0048] Furthermore, the adjusting device 5 includes a supporting seat 6 which is fixedly mounted on the base plate 2 ; an electric push rod 7 which is fixedly mounted on the top of the supporting seat 6 ; wherein the clamping plate 3 is fixedly connected to the output end of the electric push rod 7 .

[0049] Furthermore, it also includes a step surface 8 which is arranged on the inner wall of the splint 3 ; and an anti-slip pattern 9 which is arranged on the step surface 8 .

[0050] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the inner hole of the cylinder housing 1 needs to be processed, the cylinder housing 1 is placed on the bottom plate 2, the electric push rod 7 is started, and the electric push rod 7 drives the clamping plate 3 to move inward. The adjusting device 5 and the clamping plate 3 are both set to three, so that the clamping plate 3 clamps the cylinder housing 1 inward in the form of a regular triangle. The setting of the triangle is more fixed, and the cylinder housing 1 of different diameters can be matched by adjusting the stroke driven by the electric push rod 7, thereby improving the applicable range of the clamping plate 3. The bottom end of the cylinder housing 1 is supported by the step surface 8, and the upper end of the cylinder housing 1 is pressed by the pressing block 4, which effectively prevents the axial shaking of the cylinder housing 1 during processing. The contact surface between the step surface 8 and the cylinder housing 1 is provided with an anti-skid pattern 9, which effectively plays an anti-skid role and ensures the installation stability of the cylinder housing 1 during processing of the inner hole.

[0051] Embodiment 2:

[0052] like Figure 2 , Figure 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a slide groove 11, which is arranged on the support block 10; a slider 12, which is arranged at the lower end of the clamping plate 3; wherein the slider 12 can be slidably installed in the slide groove 11.

[0053] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the electric push rod 7 drives the splint 3 to move, the slider 12 at the lower end of the splint 3 moves along the slide groove 11. Through the cooperation between the slider 12 and the slide groove 11, the splint 3 is more stable when moving and is not easy to shake or dislocate.

[0054] Embodiment 3:

[0055] like Figure 2 , Figure 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: an electric magnetic block 13, which is fixedly installed in the central part of the support block 10; wherein the upper end surface of the electric magnetic block 13 is in contact with the lower end surface of the cylinder housing 1.

[0056] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the cylinder housing 1 is made of metal material, when the cylinder housing 1 is installed on the base plate 2, it is necessary to make the cylinder housing 1 and the electric magnetic block 13 concentric circles, and the concentric circles are ensured by the simultaneous driving and clamping of the three-side clamping plates 3. When the clamping of the cylinder housing 1 is completed, the electric magnetic block 13 is started, and the electric magnetic block 13 generates magnetic force to adsorb the cylinder housing 1, thereby further ensuring the installation stability of the cylinder housing 1.

[0057] Embodiment 4:

[0058] like Figure 1 , Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a pressing assembly 14, which is fixedly mounted on the base plate 2; wherein the pressing block 4 is movably connected to the pressing assembly 14, and the pressing assembly 14 and the adjusting device 5 are staggered.

[0059] Furthermore, the pressing assembly 14 includes a support sleeve 15 fixedly mounted on the base plate 2; a cylinder 16, one end of which is fixedly mounted in the support sleeve 15; and a swing arm 17, which is arranged at one end of the pressing block 4 and fixedly connected to the output end of the cylinder 16.

[0060] Furthermore, it also includes a protrusion 18, which is arranged at the top of the support sleeve 15; a pair of cylinders 19, which are respectively arranged on both sides of the protrusion 18; a pair of connecting ears 20, which are respectively fixedly connected to the lower end of the pressing block 4; wherein, the pair of connecting ears 20 can be rotatably mounted on each cylinder 19.

[0061] In this embodiment of the present application, due to the adoption of the above-mentioned structure, after the cylinder housing 1 is installed on the base plate 2 and the clamping plate 3 clamps the cylinder housing 1 in the diameter direction, the cylinder 16 of the support sleeve 15 is started, and the bottom end of the cylinder 16 moves upward to drive the swing arm 17 to rotate, and one end of the swing arm 17 pushes the pressure block 4 to rotate. At the same time, the through hole of the connecting ear 20 rotates along the cylinder 19, and the pressure block 4 rotates from top to bottom, and one end of the pressure block 4 presses the upper end surface of the cylinder housing 1. The use of the cylinder 16 can make the pressure block 4 automatically press and release the cylinder housing 1, without the need to manually lock and disassemble the pressure block 4. While ensuring the pressing effect of the pressure block 4, it is more automated and reduces manual labor.
