[0001] This utility model belongs to the field of bearing polishing technology, specifically relating to a precision bearing outer surface polishing device. Background Technology

[0002] Precision bearings are the core components for achieving high-precision and high-stability transmission, and their selection and performance directly affect the accuracy and lifespan of equipment.

[0003] For example, Chinese patent CN219666198U discloses a precision bearing outer surface polishing device, belonging to the field of bearing processing technology. It addresses the problem that existing precision bearing outer surface polishing equipment requires placing the bearing on the upper end of a positioning rod for polishing, but the bearing is prone to tipping over when sliding into the polishing wheel, affecting the conveying and polishing of the bearing and resulting in low work efficiency. The invention includes two polishing motors, each fixedly mounted on the upper end of the polishing machine; two polishing wheels, each fixedly mounted on the front end of the two polishing motors; a material rod clamped inside the polishing machine; a bearing slidably connected to the outside of the material rod; a protective mechanism located at the upper end of the polishing machine; and a clamping and discharging mechanism located inside the polishing machine. Through this design, worker protection and bearing guidance are achieved, improving safety and work efficiency.

[0004] However, in the existing technology, the end of the feed bar lacks a positioning part. When grinding the material, there is a risk that the feed bar will shift, affecting the machining accuracy of the bearing. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a precision bearing outer surface polishing device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A precision bearing outer surface polishing device includes a mounting platform. Two polishing machines are mounted on the upper side of the mounting platform. Limiting rods are provided on the inner sides of the two polishing machines. Fixing mechanisms are provided at both ends of the limiting rods to fix them. The fixing mechanisms include two sets of clamping members, each clamping member including a first arc-shaped clamping plate and a second arc-shaped clamping plate. The arc-shaped portions of the first and second arc-shaped clamping plates match the surfaces of the limiting rods. A bidirectional lead screw is assembled and connected to the lower part of the first and second arc-shaped clamping plates. The first and second arc-shaped clamping plates are symmetrically arranged. One end of the bidirectional lead screw is connected to a motor. A moving mechanism is assembled and connected to one side of the limiting rod.

[0008] Furthermore, the limiting rod is provided with slots at both ends that cooperate with the first arc-shaped clamping plate and the second arc-shaped clamping plate, and the first arc-shaped clamping plate and the second arc-shaped clamping plate are provided with protruding rings at corresponding positions of the slots.

[0009] Further specifying, the moving mechanism includes a push block, a protrusion is provided on one side edge of the push block, and the push block is assembled and connected to an electric lead screw.

[0010] Further specifying, a threaded sleeve is assembled and connected between the electric lead screw and the push block, the threaded sleeve is threadedly connected to the electric lead screw and rotatably connected to the push block, and a rotating mechanism is assembled and connected to the outer side of the push block.

[0011] Further specifying, the rotating mechanism includes a limiting tooth, which is engaged with a toothed column, and the end of the toothed column is connected to a driving mechanism.

[0012] Further specifying, the driving mechanism includes a rocker arm, the end of which is fixedly connected to the end of a limiting rod, the end of which is provided with a straight groove, a driving rod is slidably connected within the straight groove, and a telescopic cylinder is connected to the lower part of the driving rod.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention uses a limiting rod to limit the bearing, which can effectively prevent the center position of the bearing from changing when the polishing machine is polishing the bearing.

[0015] This utility model is ingeniously designed. It uses a clamping component to clamp the limiting rod, keeping the position of the limiting rod fixed. At the same time, while the clamping component at one end keeps the limiting rod fixed, the clamping component at the other end can be separated, so that the bearing can be sleeved on the limiting rod and can be entered and removed from the end of the limiting rod.

[0016] This utility model is ingeniously designed. Through the cooperation of the toothed column and the limiting tooth, when the toothed column rotates, it can drive the push block to rotate, thereby realizing the separation of the push block from the bearing. When the push block is reset, it will not contact the bearing and change the position of the bearing.

[0017] This invention uses a telescopic cylinder to drive a rocker arm to swing, thereby driving the gear column to rotate and achieving the swinging of the push block, which is simple to control. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0028] like Figure 1-4As shown, a precision bearing outer surface polishing device includes a mounting platform 1. Two polishing machines 2 are arranged on the upper side of the mounting platform 1. Limiting rods 3 are arranged on the inner side of the two polishing machines 2. Fixing mechanisms 4 are provided at both ends of the limiting rods 3 to fix the limiting rods 3. The fixing mechanism 4 includes two sets of clamping parts 41. The clamping parts 41 include a first arc-shaped clamping plate 411 and a second arc-shaped clamping plate 412. The arc-shaped parts of the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 match the surface of the limiting rod 3. A bidirectional lead screw 413 is assembled and connected to the lower part of the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412. The first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 are arranged symmetrically. One end of the bidirectional lead screw 413 is connected to a motor 414. A moving mechanism 5 is assembled and connected to one side of the limiting rod 3.

[0029] In this embodiment, the mounting platform 1 is used to install various components. The polishing machine 2 is located above the bearing to polish it. The limiting rod 3 is used to keep the center position of the bearing unchanged. The fixing mechanism 4 is used to fix the limiting rod 3, thereby fixing the position of the limiting rod 3. The fixing mechanism 4 is located at the end of the limiting rod 3. The clamping member 41 is used to clamp the limiting rod 3. The bidirectional screw 413 is used to make the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 move towards the center at the same time. The motor 414 is used to drive the bidirectional screw 413 to rotate in the forward or reverse direction, thereby driving the clamping member 41 to move in the forward or reverse direction. When the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 clamp the limiting rod 3, the first arc-shaped clamping plate 1411 and the second arc-shaped clamping plate 412 remain in contact with the limiting rod 3. The moving mechanism 5 is used to push the bearing to move.

[0030] Reference Figure 2 The limiting rod 3 has slots at both ends that mate with the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412. The first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 have protruding rings at corresponding positions in the slots. In this embodiment, the first arc-shaped clamping plate 411 and the second arc-shaped clamping plate 412 are used to keep the limiting rod 3 in a fixed position. The protruding rings are engaged in the slots to limit the position of the limiting rod 3, preventing it from moving in the left or right direction.

[0031] Reference Figure 3 and Figure 4The moving mechanism 5 includes a push block 51, a protrusion 52 is provided on one side edge of the push block 51, and an electric lead screw 53 is assembled and connected to the push block 51. In this embodiment, the push block 51 is used to push the bearing to move, thereby pushing the bearing to the position of the polishing machine 2. The protrusion 52 protrudes from the front side of the push block 51 and is used to contact the bearing to drive the push block 51 to move. The second arc-shaped clamp 412 located at the output end is located at the end of the electric screw 53. When the push block 51 can no longer move forward, the protrusion 52 can be located on the output side of the second arc-shaped clamp 412, thereby pushing the bearing to the output side of the second arc-shaped clamp 412. At this time, the first arc-shaped clamp 411 and the second arc-shaped clamp 412 at the output end are in the open state, and the bearing can be continuously moved out from the output end. The first arc-shaped clamp 411 and the second arc-shaped clamp 412 at the input end are in the state of fixing the limit rod 3. The control of the electric screw 53 is controlled by the control board, so that during the polishing of the bearing, one end of the clamp is always fixed to the limit rod 3. The setting of the slot and the protruding ring is used to limit the movement of the limit rod 3 in the horizontal direction.

[0032] Reference Figure 4 A threaded sleeve 61 is assembled and connected between the electric lead screw 53 and the push block 51. The threaded sleeve 61 is threadedly connected to the electric lead screw 53 and rotatably connected to the push block 51. A rotating mechanism 62 is assembled and connected to the outer side of the push block 51. In this embodiment, the inside of the threaded sleeve 61 is threaded, and the outside is a smooth surface. The smooth surface of the outside is rotatably connected to the push block 51. When the electric lead screw 53 rotates, it drives the threaded sleeve 61 to move. The threaded sleeve 61 drives the push block 51 to move. The rotating mechanism 62 drives the push block 51 to rotate. When the push block 51 needs to be reset, it is rotated upward, so that the push block 51 can be reset without pushing the bearing. Limit plates are connected to both ends of the threaded sleeve 61. The limit plates have sliding holes. The mounting seats at both ends of the limit rod 3 are connected to sliding rods. The sliding rods are located in the sliding holes of the limit rod 13. The threaded sleeve 61 rotates through the sliding rods, so that when the electric lead screw 53 rotates, the threaded sleeve 61 can only translate relative to the electric lead screw 53.

[0033] Reference Figure 3 The rotating mechanism 62 includes a limiting tooth 621, which meshes with a toothed column 6. The end of the toothed column 6 is connected to a driving mechanism 7. In this embodiment, the limiting tooth 621 and the toothed column 6 are meshed and connected for transmission. When the toothed column 6 rotates, it drives the limiting tooth 621 to rotate.

[0034] Reference Figure 1 and Figure 5The drive mechanism 7 includes a rocker arm 71, which is fixedly connected to the end of the limiting rod 3. The end of the rocker arm 71 has a straight groove, and a drive rod 72 is slidably connected within the straight groove. A telescopic cylinder 73 is connected to the lower part of the drive rod 72. In this embodiment, the rocker arm 71 is configured to rotate the gear column 6 when the telescopic cylinder 73 moves upward, thereby rotating the push block 51 fixedly connected to the limiting gear 621.

[0035] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
