Description

Technical Field

[0001] The utility model relates to the technical field of piston processing, and more specifically to a grinding device for piston processing. Background Technique

[0002] In order to improve the surface finish of the piston, it is necessary to grind and polish its surface and internal pin holes. Usually, manual grinding and polishing are used to improve the surface finish of the outer circle and top surface of the piston, and the machine is used to grind and polish the internal pin holes of the piston. There are many types of pistons, so the sizes of the pin holes of the pistons are also different. When the existing device for grinding the piston pin holes grinds different pin holes, it is necessary to replace grinding rods with different diameters at the same time, and the working efficiency is low. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a grinding device for piston processing is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a grinding device for piston processing to solve the problems existing in the above-mentioned background technique.

[0004] The utility model provides the following technical solutions: A grinding device for piston processing, including a placement plate, a clamping base, a lifting mechanism, and a control panel. A motor is fixedly installed at the upper end of the placement plate, a rotating shaft is fixedly installed at the power output end of the motor, one end of the rotating shaft penetrates through the placement plate movably, a hollow connecting column is installed at the penetrating end of the rotating shaft, two rows of cavities with a certain number are evenly opened on the surface of the hollow connecting column, a return spring is fixedly installed in each cavity of the hollow connecting column, a limiting block is arranged on one side of each return spring, a pushing block is fixedly installed at one end of each limiting block, and a grinding block is fixedly installed between two pushing blocks in the same vertical direction. The outer side of the grinding block is arc-shaped, and the end of the grinding block close to the clamping base is also arc-shaped.

[0005] Further, four second limiting blocks are evenly fixedly installed on the surface of the rotating shaft, a groove corresponding to the second limiting blocks is opened at one end of the hollow connecting column, a threaded hole is opened at the penetrating end of the rotating shaft, a locking screw is movably installed in the threaded hole of the rotating shaft, and the hollow connecting column and the rotating shaft are movably connected through the locking screw. After the hollow connecting column and the second limiting blocks are engaged, and the hollow connecting column is movably connected through the locking screw, it is convenient to disassemble the hollow connecting column from the rotating shaft so as to repair and replace the objects on the hollow connecting column.

[0006] Further, through holes are provided inside one end of both the pushing block and a limiting block, and one end of the return spring extends into the through holes of the limiting block and the pushing block. Through the through holes in the limiting block and the pushing block, the return spring can extend into the pushing block, so that a smaller combined diameter can be achieved between the grinding block and the hollow connecting column.

[0007] Further, a through hole is provided at the upper end of the clamping base, and the through hole is located directly below the hollow connecting column. The diameter of the through hole is larger than the maximum combined diameter of the grinding block and the hollow connecting column. When the grinding block is driven by the lifting mechanism to descend to the lowest position, the grinding block will enter the through hole, thus preventing the grinding block from damaging the surface of the clamping base during rotation.

[0008] Further, a number of through chip removal holes are provided in the upper end of the clamping base. When the grinding block grinds the material, a large amount of material powder will fall. By allowing the material powder to pass through the through chip removal holes, the material powder on the surface of the clamping base can be cleaned.

[0009] Further, a chip collection box is provided below the through chip removal holes, and the chip collection box is movably installed on one side of the clamping base. When the material falls through the through chip removal holes, the chip collection box collects the material powder, preventing the falling material powder from affecting the environment.

[0010] Technical effects and advantages of the present utility model:

[0011] 1. The present utility model is provided with a motor, a rotating shaft, a return spring, a limiting block, a pushing block, and a grinding block. During use, after the grinding block pushes the pushing block, the return spring contracts in the cavity of the hollow connecting column, so that after the combined diameter of the grinding block and the hollow connecting column changes, it can adapt to different diameters of the pin holes of the material, greatly improving the practicality of the device.

[0012] 2. The present utility model is provided with a through hole. During use, when the grinding block is driven by the lifting mechanism to descend to the lowest position, the grinding block will enter the through hole, thus preventing the grinding block from damaging the surface of the clamping base during rotation, greatly improving the practicality of the device.

Specific embodiments

[0018] 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.

[0019] Embodiment 1: Please refer to Figures 1-4 , A grinding device for piston processing provided by the present utility model includes a placing plate 100, a clamping base 101, a lifting mechanism 102, and a control panel 103. A motor 110 is fixedly installed at the upper end of the placing plate 100. A rotating shaft 111 is fixedly installed at the power output end of the motor 110. One end of the rotating shaft 111 movably penetrates through the placing plate 100. A hollow connecting column 109 is installed at the penetrating end of the rotating shaft 111. Two rows of cavities with a certain number are evenly opened on the surface of the hollow connecting column 109. Return springs 112 are fixedly installed in the cavities of the hollow connecting column 109. A first limiting block 113 is arranged on one side of each return spring 112. A pushing block 114 is fixedly installed at one end of each first limiting block 113. A grinding block 115 is fixedly installed between two pushing blocks 114 in the same longitudinal direction. The outer side of the grinding block 115 is arc-shaped, and one end of the grinding block 115 close to the clamping base 101 is also arc-shaped.

[0020] Working principle: During use, the material is placed on the clamping base 101 and fixed. The pin hole of the material will be directly opposite to the rotating shaft 111. At this time, after starting the lifting mechanism 102 through the control panel 103, the placing plate 100 is driven to descend. The arc-shaped surface at the bottom end of the grinding block 115 will slide into the material pin hole along the arc-shaped surface. When the pin hole of the material is relatively small, during the process of the grinding block 115 sliding into the material pin hole along the arc-shaped surface, the pushing block 114 will be pushed into the cavity outside the hollow connecting column 109, so that the combined diameter of the grinding block 115 and the hollow connecting column 109 adapts to the size of the material pin hole. At this time, the motor 110 is started through the control panel 103. The power output d end of the motor 110 will drive the hollow connecting column 109 to rotate, thereby driving the grinding block 115 connected through the first limiting block 113 and the pushing block 114 to rotate, and grinding the pin hole of the material.

[0021] Embodiment 2:

[0022] The difference between the second embodiment and the first embodiment is as follows: Four two-positioning blocks 120 are evenly and fixedly installed on the surface of the rotating shaft 111. A groove corresponding to the two-positioning blocks 120 is provided at one end of the hollow connecting column 109. A threaded hole is provided at the penetrating end of the rotating shaft 111. A locking screw 121 is movably installed in the threaded hole of the rotating shaft 111. The hollow connecting column 109 and the rotating shaft 111 are movably connected by the locking screw 121. Through holes are provided inside one end of both the pushing block 114 and the one-positioning block 113. One end of the return spring 112 movably extends into the through holes of the one-positioning block 113 and the pushing block 114. A through hole 123 is provided at the upper end of the clamping base 101. The through hole 123 is located directly below the hollow connecting column 109. The diameter of the through hole 123 is larger than the maximum combined diameter of the grinding block 115 and the hollow connecting column 109. A number of through chip holes 124 are provided in a penetrating manner at the upper end of the clamping base 101. A chip collection box 122 is provided below the through chip holes 124. The chip collection box 122 is movably installed on one side of the clamping base 101. During use, the hollow connecting column 109 is inserted into the rotating shaft 111 until one end of the two-positioning blocks 120 is caught on the two-positioning blocks 120. The cap of the locking screw 121 is larger than the hollow diameter of the hollow connecting column 109, thereby fixing the hollow connecting column 109 on the rotating shaft 111. When the material is being ground, the falling powder will fall into the chip collection box 122 below through the through hole 123 and the through chip holes 124. The through hole 123 prevents the grinding block 115 from coming into contact with the surface of the clamping base 101 after it descends.

[0023] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
