[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a cylinder grinding fixture includes a fixed base 1, a base plate 2 detachably fixed to the top of the fixed base 1, an adjusting cylinder 3 between the base plate 2 and the fixed base 1 and the adjusting cylinder 3 being fixed to the fixed base 1, a grinding positioning post 5 fixed to the upper surface of the base plate 2, a positioning hole 9 inside the grinding positioning post 5, a lifting adjusting rod 7 slidably disposed inside the positioning hole 9, a round hole at the bottom end of the lifting adjusting rod 7, the piston top of the adjusting cylinder 3 being inserted into the round hole at the bottom end of the lifting adjusting rod 7, and the bottom end of the lifting adjusting rod 7 penetrating the base plate 2 and contacting the adjusting cylinder 3, thus grinding... Guide holes 6 are provided on both sides of the top of the grinding positioning post 5. One end of the guide hole 6 is connected to the positioning hole 9. A pressing block 8 is slidably installed inside one of the guide holes 6. One end of the pressing block 8 is in contact with the lifting adjustment rod 7, and a return spring 10 is sleeved on the outside of this end of the pressing block 8. The lifting adjustment rod 7 is adjusted by adjusting the cylinder 3, so that the pressing block 8 is pressed when the lifting adjustment rod 7 moves up, so that the pressing block 8 extends out from the inside of the guide hole 6 and positions the workpiece sleeved on the outside of the grinding positioning post 5, ensuring that the workpiece will not shake or shift its position when it is being ground.

[0021] The top of the lifting adjustment rod 7 is provided with a limiting surface 11 facing the side of the extrusion block 8, and the bottom of the limiting surface 11 is provided with an adjustment surface 12. The top of the adjustment surface 12 is connected to the limiting surface 11 with a rounded corner. The upper part of the adjustment surface 12 is a vertical surface and the lower part is an arc surface. The adjustment surface 12 on the side of the top of the lifting adjustment rod 7 ensures that the extrusion block 8 can be extruded and extend out of the guide hole 6 when the lifting adjustment rod 7 moves upward, so that the extrusion block 8 can smoothly position the workpiece.

[0022] The bottom outer side of the grinding positioning post 5 is detachably fitted with a wear support block 4. The internal dimensions of the wear support block 4 are the same as the external dimensions of the bottom of the grinding positioning post 5. The wear support block 4 is made of aluminum alloy and has a wear-resistant coating on its outer surface. The thickness of the wear support block 4 is equal to the thickness of the workpiece. The wear support block 4 supports the workpiece from below and protects the grinding positioning post 5 to prevent it from coming into contact with the grinding tool and being worn.

[0023] The diameter of the extrusion block 8 is consistent with the inner diameter of the guide hole 6. The inner diameter of the lifting adjustment rod 7 is larger than the inner diameter of the guide hole 6, and one end of the lifting adjustment rod 7 is attached to the inner wall of the positioning hole 9. This ensures that after the extrusion block 8 is extruded, the return spring 10 can be compressed smoothly, and the return spring 10 will not fall out of the guide hole 6.

[0024] Working principle: First, the wear support block 4 is placed on the outside of the grinding positioning post 5, ensuring that the bottom of the wear support block 4 is in contact with the surface of the base plate 2. Then, the workpiece is clamped by the robotic arm, and the clamped workpiece is placed on the outside of the grinding positioning post 5. At this time, the bottom of the workpiece is in contact with the top of the wear support block 4, and the top of the workpiece is flush with the top of the grinding positioning post 5. Then, the power supply of the adjusting cylinder 3 is turned on and started. After the adjusting cylinder 3 is started, the piston rod moves upward, which drives the lifting adjusting rod 7 to move upward at the same time. After the lifting adjusting rod 7 moves upward, The adjustment surface 12 moves upward, and the changed position of the adjustment surface 12 presses the end of the pressing block 8, causing the pressing block 8 to slide outward inside the guide hole 6. At the same time, the return spring 10 is compressed until the end of the pressing block 8 extends out of the guide hole 6 and contacts the workpiece. At this time, the workpiece is fixed from the inside by the pressing block 8. The operator only needs to use a grinding tool to grind the outer surface of the grinding positioning post 5 to achieve rapid positioning of the product to be ground and ensure that the product will not shake or shift position during the grinding process.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
