A bearing sleeve inner ring planing device

Abstract

This invention relates to the field of metal planing technology and discloses a planing device for the inner ring of a bearing sleeve. It solves the problem that during the planing process of bearing sleeves, shavings easily accumulate on the cutting side of the planer, leading to reduced machining accuracy, accelerated tool wear, and affecting machining quality and continuity. The device uses a conveyor assembly to move the shavings through a claw above the planer, which cleans the shavings. The outer end of the claw is designed with multiple inserts to easily insert into the shavings, improving the success rate of shaving capture.

Description

Technical Field

[0001] This invention relates to the field of metal planing technology, specifically to a planing device for the inner ring of a bearing sleeve. Background Technology

[0002] The grooves on the inner side of the bearing sleeve for ball movement are typically machined using a planing process. Currently, planing devices for the inner ring of bearing sleeves generally include a clamping and rotating fixture, a planing fixture, and a slide module. The clamping and rotating fixture holds the bearing sleeve and rotates it, while the planing fixture is mounted on the slide module. Driven by the slide module, the planing cutter of the planing fixture enters the rotating inner side of the bearing sleeve to perform planing machining on its inner surface.

[0003] However, in actual machining processes, the planer generates a large amount of filamentous metal chips when cutting the bearing sleeve material. For example... Figures 2-3 As shown, these shavings tend to accumulate on the cutting side of the planer. As machining continues, these shavings accumulate, negatively impacting the machining accuracy of the bearing sleeve and the normal operation of the planer. Specifically, the shavings accumulated on the planer alter the actual cutting dimensions, causing changes in the effective cutting depth, resulting in the inner ring size of the machined bearing sleeve failing to meet design requirements. Furthermore, shaving accumulation at the cutting edge increases cutting force and heat, accelerating tool wear. In severe cases, accumulated chips can cause excessive stress on the cutting edge, even leading to chipping or tool breakage, thus affecting tool life and machining continuity.

[0004] Therefore, how to effectively avoid or reduce the accumulation of shavings on the planer during the planing process has become an urgent technical problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a bearing sleeve inner ring planing device, which solves the problem that during the bearing sleeve planing process, the generated shavings easily accumulate on the cutting side of the planer, leading to reduced machining accuracy, increased tool wear, and affecting machining quality and continuity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bearing sleeve inner ring planing device, comprising a machine base, a slide module and a clamping rotating fixture mounted on the machine base, the slide module being provided with a planing fixture, the planing fixture including a tool holder and a planing cutter disposed at the outer end of the tool holder, a cleaning mechanism mounted above the tool holder; the cleaning mechanism including a wire hooking assembly and a conveying assembly, multiple wire hooking assemblies being provided and evenly assembled on the upper side of the conveying assembly, the wire hooking assembly including a hook claw, the hook claw standing on one side of the conveying assembly and moving cyclically by being driven by the conveying assembly;

[0007] The cyclically moving claw passes over the planer blade from the inside of the bearing sleeve to the outside.

[0008] As a further description of the above technical solution: the transmission assembly includes a chain and two sprockets. The two sprockets support the chain above the tool holder. A motor is installed on the sprocket on the side away from the bearing sleeve. The output end of the motor is coaxially connected to the sprocket.

[0009] As a further description of the above technical solution: the hook assembly also includes an assembly seat, which is fixedly mounted on one side of the chain, and the assembly seat has an assembly part for rotating and installing the hook claw on one side.

[0010] As a further description of the above technical solution: a rotating seat is fixedly connected to one end of the hook, the rotating seat is rotatably assembled on the assembly part via a rotating shaft, a torsion spring is provided on the upper side of the rotating seat, and a ratchet structure is provided between the lower side of the rotating seat and the assembly part. The ratchet structure includes a second ratchet fixed on the lower surface of the rotating seat, and a first ratchet fixedly disposed on the assembly part and cooperating with the second ratchet.

[0011] As a further description of the above technical solution: the assembly seat is provided with a rounded corner on the side near its direction of movement, and a filling block is provided between the rounded corner and the assembly part. The filling block is used to fill the uneven area on one side of the assembly seat.

[0012] As a further description of the above technical solution: the outer side of the conveying component is provided with an assembly cover, which is used to prevent the filaments from contacting and entangled with the conveying component.

[0013] As a further description of the above technical solution: the assembly cover includes a bottom plate and a top plate, the outer edge of the bottom plate is fixedly connected with a baffle, the conveying assembly is disposed inside the baffle, and the top plate is fixed to the upper side of the chain by a pad fixedly disposed on the upper surface of the bottom plate.

[0014] As a further description of the above technical solution: a gap is provided between the baffle and the top plate for the parallel part of the mounting base to extend out, and the parallel part moves through the gap to support the mounting base on the outside of the baffle.

[0015] As a further description of the above technical solution: a wire pushing assembly is provided on the side of the assembly cover near the planer, and the wire pushing assembly is located at the end of the assembly cover near the planing fixture.

[0016] As a further description of the above technical solution: the wire pushing assembly includes a bottom block fixedly disposed on one side of the assembly cover, a pusher block fixedly disposed on the upper side of the bottom block, a pusher rod disposed at one end of the pusher block, and a guide frame disposed on the upper side of the bottom block.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. The shavings generated are cleaned by the hooks above the planer, which are driven by the conveyor assembly. The outer end of the hooks is designed with multiple inserts to smoothly insert into the shavings, improving the success rate of shaving capture. The circulating hooks clean up the generated shavings in a timely manner, avoiding the accumulation of shavings on the side of the planer used for cutting, which would change the effective cutting depth of the planer, affect the machining accuracy of the inner ring of the bearing sleeve, and increase the cutting force and cutting heat of the planer, thus accelerating the wear of the planer.

[0019] 2. By using the wire pusher assembly in conjunction with the wire hook assembly, the hook claw will rotate when it passes the wire pusher assembly, causing the hook claw to rotate and fold. This also pushes out the wire shavings inserted at the outer end of the hook claw, allowing the wire shavings to detach from the outer end of the hook claw. This prevents the wire shavings from accumulating at the outer end of the hook claw, which would affect the subsequent cleaning effect of the hook claw on the upper side of the planer blade.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0034] Combination Figures 1-11 A bearing sleeve inner ring planing device includes a machine base 10, on which a slide module 11 and a clamping and rotating fixture 13 are mounted. The slide module 11 is provided with a planing fixture 12, which includes a tool holder 14 and a planing blade 15 disposed at the outer end of the tool holder 14. The clamping and rotating fixture 13 fixes and clamps the bearing sleeve and controls the bearing sleeve to rotate along the shaft. Under the control of the slide module 11, the tool holder 14 causes the planing blade 15 at its outer end to enter the inner side of the bearing base. In conjunction with the rotating bearing sleeve, the planing blade 15 performs a planing task on the inner wall of the bearing sleeve.

[0035] A cleaning mechanism 20 is mounted above the tool holder 14. The cleaning mechanism 20 enters the inner side of the bearing sleeve together with the tool holder 14. The cleaning mechanism 20 is used to continuously clean the shavings generated when the planer 15 planes the bearing sleeve.

[0036] The outer side of the conveying component 23 is covered with an assembly cover 21, which is used to prevent the filaments from contacting and tangling with the conveying component 23.

[0037] The cleaning mechanism 20 includes a hook assembly 22 and a conveying assembly 23. The conveying assembly 23 includes a chain 232 and two sprockets 231. The two sprockets 231 support the chain 232 above the blade holder 14. A motor 25 is installed on the sprocket 231 on the side away from the bearing sleeve. The output end of the motor 25 is coaxially connected to the sprocket 231. The motor 25 drives the corresponding sprocket 231, so that the chain 232 can continuously circulate along the circumference of the sprocket 231.

[0038] The cleaning mechanism 20 includes a wire-hooking assembly 22 and a conveying assembly 23. Multiple wire-hooking assemblies 22 are provided and are evenly assembled on the upper side of the conveying assembly 23. Multiple wire-hooking assemblies 22 move in a cycle together with the movable sprocket 231. The wire-hooking assembly 22 includes a hook 221 and a mounting base 222. The mounting base 222 is fixedly mounted on one side of the chain 232. The hook 221 stands on one side of the conveying assembly 23 and moves in a cycle by being driven by the conveying assembly 23. The cyclically moving hook 221 passes over the planer 15 from the inside of the bearing sleeve to the outside.

[0039] As the planer 15 planes the inner wall of the bearing sleeve, producing shavings, the chain 232 drives the hook 221 above the planer 15 to clean up the shavings. The outer end of the hook 221 can be configured with multiple insert claws and slightly bent in the direction of movement. This design facilitates the insertion of the insert claws into the shavings, improving the success rate of shaving capture. The timely cleaning of shavings by the cyclically moving hook 221 prevents shavings from accumulating on the cutting side of the planer 15, which would change the effective cutting depth of the planer 15, affecting the machining accuracy of the inner ring of the bearing sleeve, and increasing the cutting force and heat of the planer 15, thus accelerating the wear of the planer 15.

[0040] Combination Figures 6-11 Furthermore, one side of the mounting base 222 is provided with a mounting part 2221 for rotatably mounting the hook 221. One end of the hook 221 is fixedly connected to a rotating seat 223. The rotating seat 223 is rotatably mounted on the mounting part 2221 via a rotating shaft 226. The rotating shaft 226 and the mounting part 2221 are fixedly connected, while the rotating seat 223 is movably disposed on the outer surface of the rotating shaft 226. A torsion spring 224 is provided on the upper side of the rotating seat 223. The torsion spring 224 is sleeved on the outer surface of the rotating shaft 226. One end of the torsion spring 224 is fixedly connected to the rotating seat 223, and the other end is fixedly connected to the mounting part 2221. Figures 9-10The elastic potential energy of the torsion spring 224 has the tendency to push the rotating seat 223 downward and cause the rotating seat 223 to rotate counterclockwise. A ratchet structure is provided between the lower side of the rotating seat 223 and the assembly part 2221. The ratchet structure includes a second ratchet 228 fixed to the lower surface of the rotating seat 223 and a first ratchet 227 fixed to the assembly part 2221 and cooperating with the second ratchet 228. Through the cooperation of the second ratchet 228 and the first ratchet 227, under normal conditions, the rotation of the rotating seat 223 is limited, and the clockwise rotation of the pawl 221 is further limited.

[0041] Combination Figures 9-10 Under normal conditions, the torsion spring 224 elastically drives the rotating seat 223, keeping the hook 221 upright on one side of the mounting base 222. When the hook 221 passes over the planer 15 and pulls on the generated shavings, the second ratchet 228 and the first ratchet 227 cooperate to limit the rotation of the rotating seat 223, ensuring that the hook 221 will not be passively rotated due to the toughness of the shavings, thereby preventing the hook 221 from separating from the shavings during the pulling process and ensuring the cleaning effect of the shavings.

[0042] Combination Figures 7-8 The assembly cover 21 is provided with a wire pushing assembly 24 on the side near the planer 15. The wire pushing assembly 24 is located at the end of the assembly cover 21 near the planing fixture 12.

[0043] The wire pusher assembly 24 includes a base block 244 fixedly mounted on one side of the assembly cover 21. A pusher block 241 is fixedly mounted on the upper side of the base block 244, and the upper surface of the pusher block 241 is a sloped structure. When the movable pawl 221 passes over the upper surface of the pusher block 241, the sloped structure of the pusher block 241 pushes the pawl 221 upward. Furthermore, the rotating seat 223 slides upward synchronously on the surface of the rotating shaft 226, causing the ratchet 228 to separate from the ratchet 227. A pusher bar 242 is also provided at one end of the pusher block 241. When the ratchet 228 and the ratchet 227 are in a separated state, the pusher bar 242 blocks the pawl 221, causing the pawl 221 to overcome the elastic force of the torsion spring 224 and rotate clockwise. At the same time, one side of the hook 221 is in contact with the surface of the pusher 242. The pusher 242 not only enables the hook 221 to rotate and fold, but also pushes out the shavings inserted at the outer end of the hook 221, so that the shavings are separated from the outer end of the hook 221, avoiding the accumulation of shavings at the outer end of the hook 221, which would affect the subsequent cleaning effect of the hook 221 on the shavings generated on the upper side of the planer 15.

[0044] The outer surface of the pusher 242 can be roughened to increase the friction between it and the filaments, thereby further improving the efficiency of pushing the filaments out of the outer end of the hook 221.

[0045] It should be noted that the lower side of the hook 221 is horizontal so that when the hook 221 comes into contact with the pusher 242, it can pass smoothly through the obstruction of the pusher 242.

[0046] A guide frame 243 is also provided on the upper side of the base block 244. One end of the guide frame 243 is close to the pusher bar 242, and the other end is close to the planing fixture 12. After the hook 221 is rotated and folded on one side of the assembly base 222 after passing the pusher block 241 and the pusher bar 242, the guide frame 243 limits the hook 221, keeping it in a folded state and entering the peripheral area of ​​the planing fixture 12 and the corresponding connecting sprocket 231, thereby reducing the space required for assembling the conveying component 23 on the planing fixture 12 and making the overall structure more compact.

[0047] Combination Figures 9-10 The mounting base 222 has a rounded corner 2223 on the side near its direction of movement. A filler block 225 is also provided between the rounded corner 2223 and the mounting part 2221. The filler block 225 is used to fill uneven areas on one side of the mounting base 222. The rounded corner 2223 and the filler block 225 prevent the side surface of the mounting base 222 from getting entangled with wire scraps.

[0048] Combination Figures 6-7 The assembly cover 21 includes a base plate 211 and a top plate 214. A retaining edge 212 is fixedly connected to the outer edge of the base plate 211. The conveying assembly 23 is disposed inside the retaining edge 212. The top plate 214 is fixed to the upper side of the chain 232 by a pad 213 fixedly disposed on the upper surface of the base plate 211.

[0049] A gap is provided between the retaining edge 212 and the top plate 214 for the parallel portion 2222 of the mounting base 222 to extend out. The parallel portion 2222 moves through the gap to support the mounting portion 2221 on the outside of the retaining edge 212. Since the entire conveying assembly 23 is covered inside the mounting cover 21, the filaments are isolated from the overall structure of the conveying assembly 23, preventing the filaments from contacting the sprocket 231 and chain 232, which would cause the filaments to become entangled on the structure of the sprocket 231 and chain 232, affecting the normal operation of the conveying assembly 23.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
