Description

Technical Field

[0001] This application relates to the field of cylinder bore machining technology, and in particular to an internal bore rolling device for compressors. Background Technology

[0002] A compressor is a gas pressurization machine that increases low-pressure gas to high-pressure gas. Cylinder bore machining is a key process in compressor manufacturing, primarily used to remove burrs from the inner wall of the cylinder after machining and to improve surface roughness, ensuring dimensional accuracy and surface roughness, thereby improving sealing performance and operating efficiency. Current methods for machining compressor bores typically involve using honing equipment.

[0003] The existing technical solutions mentioned above have the following drawbacks: the cost of honing equipment is high, the processing efficiency is low, and the surface wear resistance of the processed workpiece is poor. Utility Model Content

[0004] In order to reduce the cost of processing equipment, improve processing efficiency, and enhance the wear resistance of processed workpieces, this application provides an internal bore rolling device for compressors.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] An internal bore rolling device for a compressor includes a mounting base with a groove. A slider is slidably disposed in the groove, and at least two sliders are symmetrically arranged. The mounting base has fixing holes with at least two holes spaced apart. A limiting bolt passes through the fixing hole and abuts one end of the limiting bolt against the slider. An installation rod is integrally formed on the slider, and a rolling head is disposed on the installation rod. A connector is connected to the mounting base, and a connecting rod is fixedly connected to the connector.

[0007] By adopting the above technical solution, the distance between the two rolling heads is adjusted according to the inner diameter of the compressor to be rolled. The limit bolts are tightened to clamp and fix the slider in the groove. The lathe is started to drive the rolling device to rotate. The two symmetrically arranged rolling heads can increase the stability of the rolling device when rotating, so that the rolling heads roll the inner hole of the compressor. Using the rolling device to process the inner hole of the compressor can reduce the cost of processing equipment, improve processing efficiency, harden the processed surface, improve the wear resistance of the processed workpiece, and increase the fatigue strength of the processed workpiece by 30%. The rolling device can be installed on a variety of processing equipment for operation, which can improve the flexibility of processing the inner hole of the compressor.

[0009] By adopting the above technical solution, the two limiting blocks connected to the two sliders can move simultaneously towards or away from each other in the limiting groove under the drive of the limiting rack and the limiting gear. This enables the two sliders to maintain symmetry when moving towards or away from each other in the groove, increases the stability of the rolling device during rotation, ensures the safety and stability of the rolling device during use, and facilitates the adjustment of the distance between the two rolling heads by the operator.

[0010] Optionally, multiple fixing holes are symmetrically arranged along the sidewalls on both sides of the slide groove.

[0011] By adopting the above technical solution, the limiting bolts spaced apart in multiple fixing holes can increase the stability of the slider in the slide groove. The symmetrical arrangement of the limiting bolts can increase the stability of the rolling device when it rotates.

[0012] Optionally, the edges of the two sliders that are opposite to each other on one sidewall are chamfered.

[0013] By adopting the above technical solution, the chamfer formed by machining the two sliders on opposite sides can reduce the risk of damage caused by the sliders hitting the compressor or the compressor's inner hole.

[0014] Optionally, a fixing bolt is threaded through and connected to the mounting rod, and the large end of the fixing bolt abuts against the rolling head.

[0015] By adopting the above technical solution, the rolling head can be replaced by rotating and removing the fixing bolts. The rolling head is fixed to the mounting rod by the fixing bolts, which makes it convenient for staff to maintain or replace the rolling head.

[0016] Optionally, an anti-loosening bolt is provided on the mounting rod, and one end of the anti-loosening bolt abuts against the fixing bolt.

[0017] By adopting the above technical solution, the anti-loosening bolt can abut against the peripheral wall of the threaded section of the fixing bolt, which can reduce the risk of the fixing bolt loosening due to vibration generated when the rolling head is performing rolling work, and ensure the safety and stability of the rolling device during operation.

[0018] Optionally, one end of the connecting rod is machined to form a Morse taper shank.

[0019] By adopting the above technical solution, a section of the connecting rod that is machined into a Morse taper shank can be fitted with the taper hole of the lathe spindle or the tailstock sleeve of the lathe. The Morse taper shank is fixed by inserting it into the taper hole of the tailstock sleeve of the lathe. The taper structure of the Morse taper shank can automatically center itself during installation, and the friction force can provide clamping force, which facilitates the disassembly and replacement of the rolling device during the rolling operation.

[0020] Optionally, the connector head is provided with connecting bolts, and at least two connecting bolts are spaced apart. The threaded section of the connecting bolt passes through and is threadedly connected to the mounting base.

[0021] By adopting the above technical solution, the connector is fixed to the mounting base by connecting bolts, which makes it convenient for workers to maintain and replace the connecting rod of the rolling device according to the rolling work requirements, extend the service life of the rolling device, make it convenient for workers to fix the rolling device on different fixtures, and make it convenient to install the rolling device on different processing equipment for operation, thereby improving the flexibility of compressor inner hole processing.

[0022] In summary, this application has the following technical effects:

By setting limit grooves, limit gears, limit blocks, and limit racks, the two sliders can maintain symmetry when moving towards or away from each other in the slide groove, which increases the stability of the rolling device during rotation, ensures the safety and stability of the rolling device during use, and makes it easy for operators to adjust the distance between the two rolling heads.

[0025] 3.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses an internal bore rolling device for a compressor, referring to... Figure 1 The rolling device includes a mounting base 1, on which a sliding groove 11 is provided. Both ends of the sliding groove 11 connect to the side walls of the mounting base 1. A slider 2 is slidably disposed within the sliding groove 11. Two sliders 2 are symmetrically arranged, and the edges of the side walls opposite to each other on one side of the slider 2 are chamfered. The mounting base 1 has fixing holes 12, multiple of which are symmetrically arranged along the side walls of both sides of the sliding groove 11. The fixing holes 12 are perpendicular to the side walls of the sliding groove 11, with one end connecting to the side wall of the sliding groove 11. A limiting bolt 13 passes through the fixing hole 12, with the end of the limiting bolt 13 near the slider 2 abutting against the slider 2. The portion of the slider 2 opposite to the mounting base 1 extends... A mounting rod 21 is integrally formed with a slide groove 11. A rolling head 211 is sleeved on the peripheral wall of the mounting rod 21 away from the slider 2. A fixing bolt 22 is threaded through and connected to the end of the mounting rod 21 away from the slider 2. The large end of the fixing bolt 22 abuts against the rolling head 211. A connector 3 is connected to the side of the mounting base 1 away from the slide groove 11. A connecting bolt 31 is threaded through the connector 3. Multiple connecting bolts 31 are arranged at intervals along the connector 3. The threaded section of the connecting bolt 31 is threaded through and connected to the mounting base 1. A connecting rod 32 is integrally formed on the side of the connector 3 away from the mounting base 1. A Morse taper shank 33 is formed on the part of the connecting rod 32 away from the connector 3.

[0031] Reference Figure 2 A limiting groove 14 is provided at the bottom of the slide groove 11. A limiting gear 15 is rotatably arranged in the limiting groove 14. A limiting block 16 is slidably arranged in the limiting groove 14. Two limiting blocks 16 are symmetrically arranged. A limiting rack 17 is integrally formed on the side of the two limiting blocks 16 facing each other. The two limiting racks 17 are respectively attached to the two symmetrical side walls of the limiting groove 14, and both limiting racks 17 are meshed with the limiting gear 15. A limiting rod 18 is integrally formed on the side of the limiting block 16 facing the slider 2. A limiting hole 23 is opened on the side of the slider 2 facing the limiting block 16 for the limiting rod 18 to be inserted. The limiting rods 18 of the two limiting blocks 16 are respectively inserted into the limiting holes 23 of the two sliders 2.

[0032] Reference Figure 2An anti-loosening bolt 221 is threaded through and connected to the side wall of the mounting rod 21 near the slider 2. The end of the anti-loosening bolt 221 near the fixing bolt 22 abuts against the fixing bolt 22.

[0033] When using this rolling device, the connecting rod 32 is fixed on the lathe's three-jaw chuck. The distance between the two rolling heads 211 is adjusted according to the diameter of the compressor's inner hole to be rolled. Multiple limiting bolts 13 are tightened to clamp and fix the slider 2 in the slide groove 11. The multiple spaced limiting bolts 13 can increase the stability of the slider 2 in the slide groove 11. The symmetrical arrangement of the limiting bolts 13 can increase the stability of the rolling device when it rotates. The lathe is started to drive the rolling device to rotate. The two symmetrically arranged rolling heads 211 can increase the stability of the rolling device when it rotates.

The rolling head 211 is fixed to the mounting rod 21 by the fixing bolt 22, which facilitates maintenance or replacement of the rolling head 211 by the staff. The anti-loosening bolt 221 can abut against the peripheral wall of the threaded section of the fixing bolt 22, which can reduce the risk of the fixing bolt 22 loosening due to vibration generated during the rolling operation of the rolling head 211, and ensure the safety and stability of the rolling device during operation.

[0036] The connector 3 is fixed to the mounting base 1 by the connecting bolt 31, which makes it easy for the staff to maintain and replace the connecting rod 32 of the rolling device according to the rolling work requirements, extend the service life of the rolling device, make it easy for the staff to fix the rolling device on different fixtures, and make it easy to install the rolling device on different processing equipment for operation, thereby improving the flexibility of the compressor inner hole processing.

It is fixed by inserting the Morse taper shank 33 into the taper hole of the lathe tailstock sleeve. The taper structure of the Morse taper shank 33 can automatically center itself during installation, and the friction force can provide clamping force, which facilitates the disassembly and replacement of the rolling device during rolling operation.
