Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and more specifically, to a high-precision grinding device for bearing rings with bottom surface clearance cyclic fixation. Background Technology

[0002] As a key component of bearings, the machining accuracy of bearing rings directly affects the performance and service life of bearings. Grinding is a crucial step in the machining process of bearing rings, aiming to improve the dimensional accuracy and surface quality of the rings.

[0003] However, existing bearing ring grinding equipment generates a large amount of debris during the grinding process. If this debris is not cleaned in time, it will adhere to the surface of the bearing ring and affect the subsequent grinding effect. Usually, after grinding, it is necessary to carry out an additional cleaning process after conveying the ring through a conveyor fixture. However, the debris will remain on the transmission fixture, which increases the production process and cost. Moreover, traditional debris cleaning methods are often inefficient.

[0004] Since it is not possible to effectively perform multi-stage deshaving operations immediately after the bearing rings are ground, thus reducing production processes and costs, a solution is provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-precision grinding device for bearing rings with bottom surface gap cyclic fixation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-precision grinding device for bearing rings with bottom surface gap cyclic fixation includes a bottom support base, on which two sets of bottom limit seats are installed. An inner limit ring is fixedly provided on the top wall of the bottom limit seat. A toothed ring plate is provided on the outer side of the inner limit ring and is connected to it in a transmission. A gear is provided on the outer side of the toothed ring plate to drive it.

[0008] The top of the gear ring plate is fixedly provided with a grinding outer cover. Two sets of limiting vertical plates are symmetrically slidably installed inside the grinding outer cover. A grinding inner cover is fixed between the two sets of limiting vertical plates. Two sets of mounting slots are symmetrically opened inside the grinding inner cover. A second cylinder is fixedly inserted into the mounting slot. A clamping plate for grinding and fixing the bearing is fixedly provided at the extended end of the second cylinder. The two sets of clamping plates are symmetrically arranged with respect to the center line of the grinding inner cover.

[0009] Furthermore, an air pump is fixedly installed on the top of the limiting vertical plate, an annular groove is opened on the inner wall above the grinding inner cover, and a dust removal inclined pipe connected to the annular groove is also opened on the inner wall of the grinding inner cover.

[0010] Furthermore, the groove of the dust removal inclined pipe gradually decreases from the side close to the annular groove to the side away from the annular groove, and the output end of the air pump is provided with an air pipe connected to the annular groove.

[0011] Furthermore, the bottom of the grinding inner cover is provided with a material feeding seat corresponding to the grinding inner cover, and two sets of cylinders are symmetrically arranged above the bottom limit seat, and the extended end of cylinder is fixedly connected to the material feeding seat.

[0012] Furthermore, the material feeding seat has a feeding groove inside, and the cross-sectional area of ​​the feeding groove is funnel-shaped.

[0013] Furthermore, a drive shaft is provided in the middle of the drive gear, and a motor for driving the drive shaft is provided in the bottom limit seat.

[0014] Furthermore, the top of the grinding inner cover is provided with a grinding fixture, which includes a mounting bracket fixedly installed on the top wall of the bottom support. A cylinder three is vertically inserted into the mounting bracket, and a fixing plate is fixedly installed at the extended end of the cylinder three. A cylinder four is vertically inserted above the fixing plate, and a grinding component is fixedly installed at the extended end of the cylinder four.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention employs a multi-stage debris removal method. During the grinding process, the debris generated can fall off from below the grinding inner cover. On the other hand, the air pump operates to allow gas to enter the annular groove through the air pipe and then blow it out from the dust removal inclined pipe, blowing off the debris above the bearing ring. Furthermore, the outer and inner walls of the bearing ring can be cleaned and dusted simultaneously at different stages. It can also further shake off debris during the falling process of the bearing ring, greatly reducing subsequent processing steps and improving grinding quality.

[0017] 2. This invention utilizes a cylinder to control the separation and contact between the feed seat and the bottom of the grinding inner cover, facilitating the separation and dropping of debris from the connection between the bearing ring and the feed seat at the appropriate time. This is further aided by the dust removal oblique opening to remove debris, while also facilitating the feeding of the bearing ring. Attached Figure Description

[0026] 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.

[0027] Example 1: Please refer to Figures 1-6 As shown, the problem that existing technologies cannot effectively perform multi-stage chip removal immediately after bearing ring grinding to reduce production processes and lower production costs can be solved by the following solution;

[0028] This embodiment of a high-precision grinding equipment for bearing rings with bottom surface gap cyclic fixation includes a bottom support 1, two sets of bottom limit seats 2 are installed on the bottom support 1, an inner limit ring 6 is fixedly provided on the top wall of the bottom limit seat 2, a toothed ring plate 3 is provided on the outer side of the inner limit ring 6 for transmission connection, and a gear for driving it is provided on the outer side of the toothed ring plate 3.

[0029] Please see Figures 1-4 As shown, a grinding outer cover 4 is fixedly provided on the top of the toothed ring plate 3. Two sets of limiting vertical plates 9 are symmetrically slidably installed inside the grinding outer cover 4. A grinding inner cover 10 is fixedly provided between the two sets of limiting vertical plates 9. Two sets of mounting slots are symmetrically opened inside the grinding inner cover 10. A cylinder 101 is fixedly inserted in the mounting slot. A clamping plate 102 for grinding and fixing the bearing is fixedly provided at the extended end of the cylinder 101. The two sets of clamping plates 102 are symmetrically arranged with respect to the center line of the grinding inner cover 10.

[0030] It should be added that: the bearing ring is clamped and fixed by the clamping plate 102 driven by the cylinder 2 101, which ensures the stability of the bearing ring position during the grinding process. With the help of the grinding fixture, high-precision grinding can be achieved, which effectively improves the processing accuracy of the bearing ring.

[0031] Please see Figure 1-2 , Figure 4-5 As shown, an air pump 201 is fixedly installed on the top of the limiting vertical plate 9. An annular groove 203 is opened on the inner wall above the grinding inner cover 10. A dust removal inclined pipe 204 connected to the annular groove 203 is also opened on the inner wall of the grinding inner cover 10. The groove of the dust removal inclined pipe 204 gradually decreases from the side close to the annular groove 203 to the side away from the annular groove 203. An air pipe 202 connected to the annular groove 203 is provided at the output end of the air pump 201.

[0032] It should be noted that the air pump 201 is a device in the prior art that has the function of inflating the inside of the annular groove 203. It will not be described in detail here. The specific model is set according to the actual use.

[0033] Please see Figure 1-4 As shown, the bottom of the grinding inner cover 10 is provided with a material feeding seat 8 corresponding to the grinding inner cover 10, and two sets of cylinders 7 are symmetrically arranged above the bottom limit seat 2, and the extended end of the cylinder 7 is fixedly connected to the material feeding seat 8.

[0034] It should be added that the separation and contact between the feed seat 8 and the bottom of the grinding inner cover 10 are controlled by the cylinder 7, which makes it convenient to separate and drop the debris at the connection between the bearing ring and the feed seat 8 at the appropriate time, and further remove the debris with the dust removal oblique mouth, while facilitating the feeding of the bearing ring.

[0035] Please see Figure 1-2 , Figure 4 As shown, the material feeding seat 8 has a material feeding groove inside, and the cross-sectional area of ​​the material feeding groove is funnel-shaped;

[0036] The drive gear 5 has a drive shaft in the middle, and the bottom limit seat 2 has a motor that drives the drive shaft.

[0037] The following explanation is provided regarding the above content:

[0038] The bearing ring is placed inside the grinding inner cover 10, with the bottom of the bearing ring in contact with the top of the unloading seat 8. Then, the extended end of the control cylinder 101 extends outward, and the bearing ring is clamped by the two clamping plates 102. The top of the bearing ring is then subjected to high-precision grinding by the grinding fixture. The debris generated during the grinding process falls through the bottom of the grinding inner cover 10, that is, the falling path passes through the grinding inner cover 10, the unloading seat 8, the bottom limit seat 2, and the bottom support seat 1 in sequence. At the same time, the air pump 201 is turned on, and the gas enters the annular groove 203 through the air pipe 202, and then blows out through the dust removal inclined pipe 204 outside the annular groove 203 to blow off the debris above the bearing ring. At this time, the outer side of the bearing ring is mainly cleaned because the top side wall of the bearing ring is higher than the top side wall of the grinding inner cover 10, which facilitates grinding.

[0039] The extension end of the control cylinder 7 retracts, separating the feed seat 8 from the bottom of the grinding inner cover 10. The debris at the connection between the bearing ring and the feed seat 8 falls off after being separated by the feed seat 8. In conjunction with the operation of the dust removal inclined port, the debris on the outside of the bearing ring is further removed.

[0040] The control air pump 201 continues to work, the extended ends of the two sets of cylinders 101 retract, the clamping plate 102 contacts the fixing of the bearing ring, and the bearing ring falls above the feeding seat 8. At this time, the top side wall of the bearing ring is lower than the dust removal inclined pipe 204. The air blown out of the dust removal inclined pipe cleans and removes dust from the inner and outer walls of the bearing ring simultaneously. In the process of the bearing ring falling onto the feeding seat 8, the debris is further shaken off.

[0041] The above steps are used to remove grinding debris from the bearing races step by step, reducing subsequent processing steps and improving the grinding quality of the bearing races.

[0042] The bearing ring is held in place by the feeding seat 8 for easy clamping. Then the feeding seat 8 moves down, and there is a gap between the bearing ring and the feeding seat 8 to facilitate the accumulation of debris before the bearing ring is dropped back onto the feeding seat 8. The bearing ring is then held in place again. By using the above-mentioned "bottom gap cyclic holding" method, the outer and inner walls of the bearing ring can be cleaned and dusted simultaneously at different stages. The bearing ring also shakes off debris during its fall, greatly reducing the subsequent processing steps and improving the grinding quality.

[0043] Debris falling through the bottom support 1 is collected uniformly by external equipment;

[0044] Example 2: Please refer to Figure 1-2 , Figure 4 , Figure 6 As shown, supplementary explanations are provided based on Example 1;

[0045] The grinding fixture includes a mounting bracket 303 fixedly installed on the top wall of the base support 1. A cylinder 302 is vertically inserted into the mounting bracket 303. A fixing plate 301 is fixedly installed at the extended end of the cylinder 302. A cylinder 4 305 is vertically inserted above the fixing plate 301. A grinding part 304 is fixedly installed at the extended end of the cylinder 4 305.

[0046] In this embodiment: First, the extended end of cylinder 302 is controlled to extend and move the grinding part 304 above the bearing ring. Then, the extended end of cylinder 405 is controlled to descend and move the grinding head above the grinding part 304 onto the bearing ring. As the bearing ring rotates and the grinding head starts, the top wall of the bearing ring is ground.

[0047] Combining Example 1 and Example 2, it can be seen that:

[0048] Employing a multi-stage chip removal method, the chips generated during grinding can fall off from below the grinding inner cover 10. Simultaneously, the air pump 201 operates, directing air through the air pipe 202 into the annular groove 203, which then blows out through the dust removal inclined pipe 204, dislodging chips above the bearing rings. Furthermore, it can simultaneously clean and remove dust from the outer and inner walls of the bearing rings at different stages. It can also further vibrate off chips as the bearing rings fall, significantly reducing subsequent processing steps and improving grinding quality. The overall equipment has a reasonable structural layout, with all components working collaboratively. By controlling the extension and retraction of different cylinders, a series of operations such as clamping, grinding, cleaning, and unloading can be achieved. It boasts a high degree of automation, is easy to operate, and is conducive to improving production efficiency.
