Rotary row grinding station for bearing ring faces

Abstract

This invention discloses a rotating discharge grinding station for bearing ring end faces, specifically relating to the field of bearing ring processing. It includes a base platform, a housing fixedly mounted on the top of the base platform, and multiple grinding machines arranged on the inner wall of the housing. A conveying and turning mechanism and a pushing and clamping mechanism are arranged at the bottom of each grinding machine. This invention utilizes the conveying and turning mechanism and the pushing and clamping mechanism to slide and control the clamping width of a tray plate. A synchronous belt drives the tray plate supporting the bearing rings, allowing the bearing rings placed on the tray plate to continuously enter the grinding area and rotate to a replacement position after processing. This facilitates continuous grinding of a large number of bearing rings of different diameters, improving the grinding efficiency of the bearing rings. When the bearing rings rotate out after grinding, they are lifted and detached for easy retrieval of the processed bearing rings.

Description

Technical Field

[0001] The present invention relates to the technical field of bearing ring processing, and more particularly to a rotary discharge type grinding station for the end surface of a bearing ring. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Sliding bearings have no inner and outer rings and no rolling elements. They are generally made of wear-resistant materials and are often used in mechanical rotating parts with low speed, light load and lubricating oil. The sliding contact surface of spherical bearings is spherical, which is mainly suitable for swinging motion, tilting motion and rotational motion.

[0003] The traditional end face grinding process of a bearing ring is to place the bearing ring in a grinder, and then use a rotating tooth column to push the outer wall tooth block of the bearing ring to rotate to grind the end face.

It is impossible to take out the processed bearing rings before shutting down, and it is impossible to achieve continuous and coherent processing of bearing rings. Multiple bearing rings can only be processed in batches, which makes the grinding efficiency of a large number of bearing rings low.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1: Since the prior art uses a circular and closed grinding platform, only a certain number of bearing rings can be placed when grinding the end face of the bearing ring, and only bearing rings of the same diameter can be handled. It is impossible to take the processed bearing rings before stopping the machine, and it is impossible to continuously and coherently process the bearing rings. Multiple bearing rings can only be processed in batches, which makes the grinding efficiency of a large number of bearing rings low. In order to solve this problem, the following technical solution is proposed:

[0027] Refer to the instruction manual Figure 1-Figure 7 , for rotating row grinding stations for bearing ring end faces, such as Figure 1 and Figure 2 As shown, it comprises a base platform 1, a cover box 2 is fixedly installed on the top of the base platform 1, a plurality of grinders 3 are arranged on the inner wall of the cover box 2, and a conveying and rotating mechanism 4 and a pushing and clamping mechanism 5 are arranged at the bottom of the grinder 3;

[0028] like Figure 2 and Figure 3 As shown, the conveying and turning mechanism 4 includes a motor 41 fixedly mounted on the inner wall of the base platform 1, and a rotating pulley 42 is provided on the top of the motor 41. There are two rotating pulleys 42, and the two rotating pulleys 42 are rotatably mounted on the top of the base platform 1. The outer walls of the two rotating pulleys 42 are jointly rotatably mounted with a synchronous belt 43, and the outer wall of the synchronous belt 43 is fixedly mounted with a plurality of squeezing blocks 44, and the plurality of squeezing blocks 44 are arranged equidistantly in a circular shape, and then the rotating pulley 42 is driven by the motor 41 to make the synchronous belt 43 rotate synchronously, and the synchronous belt 43 drives the plurality of squeezing blocks 44 to rotate synchronously in a circle, and the plurality of squeezing blocks 44 can drive the bearing rings that are closely meshed with them.

[0029] like Figure 3 and Figure 4As shown, a plurality of synchronous plates 45 are fixedly mounted on the bottom of the outer wall of the synchronous belt 43. The plurality of synchronous plates 45 are arranged horizontally and are arranged equidistantly in a circular shape, that is, the synchronous belt 43 drives the plurality of synchronous plates 45 to rotate synchronously.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the outer walls of the multiple synchronous plates 45 are slidably installed with sliding plates 46, and the tops of the multiple sliding plates 46 are fixedly installed with pallet plates 47. The rotation of the multiple synchronous plates 45 drives the sliding plates 46 on their outer walls to make the pallet plates 47 rotate synchronously. The multiple pallet plates 47 are arranged in a horizontal state, and the tops of the multiple pallet plates 47 are fixedly installed with limited pads 48, and the limited pads 48 are arranged vertically upward, so that the pallet plates 47 drive the limited pads 48 to rotate synchronously, and the pallet plates 47 and the limited pads 48 can support the bearing rings placed on the tops.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the pushing and clamping mechanism 5 includes a flat strip plate 51 fixedly mounted on the outer walls of multiple synchronous plates 45, and the multiple flat strip plates 51 are arranged in a horizontal state. Sliding push rods 52 are slidably mounted on the inner walls of both sides of the multiple flat strip plates 51. Two sliding push rods 52 are fixedly mounted on the outer wall of the sliding pad 46. The two sliding push rods 52 are arranged in a horizontal state. A limiting spring 53 is fixedly mounted on the outer wall of the flat strip plate 51. The limiting spring 53 is fixedly mounted on the outer wall of the sliding pad 46, and then the two limiting springs 53 on the outer wall of the flat strip plate 51 elastically squeeze the sliding pad 46, and the outer walls of the two sliding push rods 52 are fixedly mounted with a clamping plate 54, and the clamping plate 54 can drive the two sliding push rods 52 to move synchronously, so that the sliding pad 46 can drive the tray plate 47 and the limiting pad column 48 under the action of the two limiting springs 53, so that the tray plate 47 and the limiting pad column 48 make the bearing ring close to the outer wall of the synchronous belt 43.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, a compression strip 55 is provided between the flat strip plate 51 and the clamping plate 54. The compression strip 55 is fixedly mounted on the top of the base platform 1. The compression strip 55 is arranged in an L shape and in a horizontal state. The compression strip 55 and the clamping plate 54 are arranged to be staggered with each other. Then, through the limitation of the compression strip 55, when the flat strip plate 51 and the clamping plate 54 rotate close to each other and staggered with the compression strip 55, the position of the compression strip 55 squeezes the flat strip plate 51 and the clamping plate 54 in the rotating process, so that the clamping plate 54 is pushed by the compression strip 55 to move outward, that is, the clamping plate 54 drives the sliding push rod 52 to move and slide out synchronously.

[0033] In the specific implementation, the flat strip plate 51 and the clamping plate 54 located on the squeezing strip 55 are rotated and pushed and pulled apart by the squeezing strip 55, so that the clamping plate 54 drives the sliding push rod 52 to make the sliding pad plate 46 slide outward, that is, the sliding pad plate 46 compresses the two limit springs 53 and drives the tray plate 47 and the limit pad column 48 to move out, at this time, the bearing ring is placed on the tray plate 47 and the limit pad column 48, and then the motor 41 drives the rotating pulley 42 to make the synchronous belt 43 continue to rotate, so that the flat strip plate 51 and the clamping plate 54 are pushed and pulled apart by the squeezing strip 55. When the plate 54 is separated from the compression strip 55, the tray plate 47 and the limiting column 48 on the sliding plate 46 are pressed by the elastic force of the limiting spring 53 to support the multiple squeezing blocks 44 on the outer wall of the synchronous belt 43 of the bearing ring, so that the bearing ring is limited and driven to perform circular motion, and is continuously and stably processed by multiple grinders 3, which makes it easy to deal with bearing rings of different diameters and enables a large number of bearing rings to be continuously ground, thereby improving the grinding efficiency of the bearing rings.

[0034] Embodiment 2: In view of the fact that the prior art does not have a structure capable of quickly taking out the processed bearing ring, which makes it inconvenient to take out the bearing ring, and affects the processing efficiency of the bearing ring, the following technical solution is proposed to solve this problem:

[0035] like Figure 6 and Figure 7 As shown, a squeezing and lifting mechanism 6 is provided on the top of the base platform 1, and the squeezing and lifting mechanism 6 includes a scraper plate 61 arranged on one side of the pallet plate 47, the scraper plate 61 is located on the outer wall of the synchronous belt 43, and the top of the scraper plate 61 is arranged in an inclined state, and the bottom of the scraper plate 61 is in contact with the top of the pallet plate 47, and a fixed support plate 62 is fixedly installed on one side of the scraper plate 61, and a supporting plate 63 is fixedly installed on the outer wall of the fixed support plate 62, and the supporting plate 63 is fixedly installed on the top of the base platform 1. After the pallet plate 47 driven by the synchronous belt 43 rotates one circle, it approaches the scraper plate 61 driven by the supporting plate 63 and the fixed support plate 62, and the inclined surface of the scraper plate 61 scrapes the bearing ring on the top of the pallet plate 47, so as to facilitate the lifting of the bearing ring on the pallet plate 47.

[0036] like Figure 6 and Figure 7 As shown, a secondary top plate 64 is fixedly installed on one side of the fixing support plate 62, and the secondary top plate 64 is arranged in a horizontal state. The length of the secondary top plate 64 is greater than the length of the fixing support plate 62, and the horizontal height of the bottom of the secondary top plate 64 is higher than the horizontal height of the top of the limiting pad column 48, so that the bearing ring lifted by the scraper rocker 61 moves up to the fixing support plate 62, and the bearing ring is supported by the secondary top plate 64, so that the processed bearing ring can be taken out easily.

[0037] During the specific implementation, after the pallet plate 47 driven by the synchronous belt 43 rotates one circle, it approaches the scraper plate 61 driven by the supporting plate 63 and the fixed supporting plate 62, and the inclined surface of the scraper plate 61 scrapes up the bearing ring on the top of the pallet plate 47, so that the bearing ring on the pallet plate 47 can be lifted, and then the bearing ring lifted by the scraper plate 61 moves up to the fixed supporting plate 62, and the bearing ring is supported by the auxiliary top plate 64, so that the processed bearing ring can be taken out.
