Description

Technical Field

[0001] The utility model relates to the technical field of compressor cylinder honing heads, in particular to a compressor cylinder honing head body. Background Art

[0002] The compressor cylinder is a fixed component fastened to the compressor body, crankcase, or center body, and cooperates with the piston to compress the gas. It is generally composed of three parts: the cylinder head, cylinder block, and cylinder seat, or two parts: the cylinder head and cylinder block. When processing the compressor cylinder, honing is generally performed inside the cylinder. Honing, also known as boring, is a finishing process performed on the finished surface using an oilstone (also known as a honing stick) embedded in a honing head. However, since the size of a general honing head is fixed, the honing range is fixed. If it is necessary to hone compressor cylinders of different sizes, the honing head and honing rod can only be replaced to hone the cylinder, which is very limited. For this reason, we propose a compressor cylinder honing head body. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a compressor cylinder honing head body.

[0004] The technical solution adopted by the utility model to solve the technical problem is a compressor cylinder honing head body, which includes a honing head body, a sanding bar seat is installed on the outer peripheral surface of the honing head body, and the sanding bar seat has multiple groups. The outer wall surface of the sanding bar seat is equipped with an oil stone layer for honing the compressor cylinder, an adjustment pin is installed between the sanding bar seat and the honing head body, and the adjustment pin has multiple groups. An adjustment cone that fits the adjustment pin is slidably installed in the honing head body, and the adjustment cone has multiple groups.

[0005] The outer periphery of the honing head body is equipped with bolt bodies for tightening, and there are multiple groups of bolt bodies. A pressure block abutting against the adjustment cone is slidably installed in the honing head body, and an adjustment bolt connected to the adjustment cone is clamped in the pressure block.

[0006] By adopting the above technical solution, when the honing head is used to hone the compressor cylinder, the adjustment cone inside the honing head body can be displaced, and the adjustment cone displacement is convenient for abutting and fitting with the adjustment pin, thereby providing thrust for the adjustment pin under the fitting pressure, so that the adjustment pin can push back the sanding strip seat, so that the sanding strip seat can drive the oilstone layer and the inner wall of the compressor cylinder to abut each other. At the same time, the honing head body can conveniently drive the oilstone layer to hone the inner wall of the cylinder as the honing rod rotates, and only by replacing the sanding strip seat with different thicknesses, the range of cylinder diameters that can be honed by the honing head body can be expanded, which is convenient for honing cylinders with different cylinder diameters.

[0007] When installing the honing head, the multiple sets of bolts on the outer periphery of the honing head body facilitate the tightening between the honing head and the honing rod, and are also convenient for disassembly and assembly. The honing head can be disassembled and replaced without changing the size of the honing rod, which facilitates the replacement of honing heads with different outer diameters. At the same time, the adjusting bolts inside the honing head body are conveniently connected to the thrust assembly inside the honing rod, so that the adjusting bolts can drive the pressure block to move inside the honing head body and push the adjusting cone to move, so that the adjusting cone can fit with the adjusting pin and provide thrust for it, which is convenient for honing the compressor cylinder.

[0008] Specifically, the outer wall surface of the sand bar seat is equipped with pin bodies for fixing the adjustment pins, and there are multiple groups of pin bodies.

[0009] By adopting the above technical solution, the multiple groups of pins on the periphery of the sand bar seat are conveniently connected to and fixed with the adjustment pins, and the pins are conveniently disassembled and assembled, making it easy to replace the sand bar seat.

[0010] Specifically, a spacer located on the periphery of the adjusting bolt is assembled between the pressing block and the adjusting cone.

[0011] By adopting the above technical solution, the pad can provide auxiliary support between the pressing block and the adjusting cone, so that the pressing block can push the adjusting cone to move more stably.

[0012] Specifically, springs located inside the honing head body are installed between the multiple groups of sanding strip seats.

[0013] By adopting the above technical solution, the spring is located between the multiple groups of sand bar seats, which facilitates providing elastic support and tensioning force for the multiple groups of sand bar seats inside the honing head body, so that the sand bar seats opened on the periphery of the honing head body can return to their original positions after use.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The technical solution of the present application, through the design of the oilstone layer, sanding strip seat, adjusting cone and adjusting pin, can make the adjusting cone inside the honing head body displace when the compressor cylinder is honed by the honing head. The displacement of the adjusting cone is convenient for abutting and fitting with the adjusting pin, thereby providing thrust for the adjusting pin under the fitting pressure, so that the adjusting pin can push back the sanding strip seat, so that the strip seat can drive the oilstone layer to abut against the inner wall of the compressor cylinder. At the same time, the honing head body can conveniently drive the oilstone layer to hone the inner wall of the cylinder as the honing rod rotates, and only by replacing the sanding strip seat with different thicknesses, the range of cylinder diameters that can be honed by the honing head body can be expanded, which is convenient for honing cylinders with different cylinder diameters.

[0016] 2. The technical solution of the present application utilizes the design of the bolt body, adjusting bolt and pressure block. When the honing head is installed, the multiple groups of bolt bodies on the outer periphery of the honing head body facilitate the tightening of the honing head and the honing rod, and are also convenient for disassembly and assembly. The honing head can be disassembled and replaced without changing the size of the honing rod, which facilitates the replacement of honing heads with different outer diameters. At the same time, the adjusting bolt inside the honing head body is conveniently connected to the thrust assembly inside the honing rod, so that the adjusting bolt can drive the pressure block to move inside the honing head body and push the adjusting cone to move, so that the adjusting cone can easily fit with the adjusting pin and provide thrust for it, thereby facilitating the honing of the compressor cylinder.

[0024] When installing the honing head, the multiple groups of bolt bodies 6 on the periphery of the honing head body 1 facilitate the tightening between the honing head and the honing rod, and are also convenient for disassembly and assembly. The honing head can be disassembled and replaced without changing the size of the honing rod, which facilitates the replacement of honing heads with different outer diameters. At the same time, the adjusting bolt 9 inside the honing head body 1 is conveniently connected to the thrust assembly inside the honing rod, so that the adjusting bolt 9 can drive the pressure block 10 to move inside the honing head body 1 and push the adjusting cone 7 to move, so that the adjusting cone 7 is convenient for fitting with the adjusting pin 5 and providing thrust for it, thereby facilitating the honing of the compressor cylinder.
