Description

Technical Field

[0001] The utility model relates to the technical field of bearing retainer processing, in particular to a processing and positioning fixture for a split bearing retainer. Background Art

[0002] A split bearing cage is a mechanical component used to support and position rolling elements (such as balls or rollers). It generally consists of two parts. The main purpose of this design is to achieve easy assembly and disassembly. Split bearing cages are widely used in modern machinery, automobiles, aerospace and other fields. Especially in equipment with high precision requirements, they are an indispensable component. Although current processing technology has made certain progress in the production of bearing cages, there are still many shortcomings. First, existing processing methods mostly rely on traditional processing equipment, which often cannot meet the needs of high-end applications in terms of accuracy and efficiency. Secondly, inaccurate positioning during the processing process can easily lead to out-of-tolerance geometric dimensions of the finished product, affecting the performance and reliability of the bearing. In addition, in complex processing processes, the lack of corresponding fixture equipment requires operators to rely on experience for manual adjustments, further increasing instability and failure rates.

[0003] During the use of the positioning fixture, since the retainer needs to be split and removed from the bearing, the outer ring of the bearing needs to be fixed and clamped. Otherwise, the retainer will move under the force when it is removed from the bearing, making it impossible to stably split and remove it from the bearing. Utility Model Content

[0004] The disclosed embodiment relates to a positioning fixture for processing a split bearing retainer, wherein an anti-slip plate cooperates with a clamping plate to fix and clamp the outer ring of the bearing, making it convenient for the retainer to be split and removed from the bearing. The shape and layout of the fixture, as well as the reasonable structural design, also help to improve the stability of the fixture, ensure that no offset or vibration occurs during the processing process, and reduce the inability to remove the retainer from the bearing due to the instability of the fixture, thereby saving time and improving efficiency.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described 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.

[0023] Example 1: Please refer to Figures 1 to 4 :

[0024] The utility model proposes a split bearing retainer processing positioning fixture, comprising: a workbench 1; support columns are fixedly installed at the four corners of the bottom of the workbench 1; the four support columns stably support the entire workbench 1, and the two ends of the top of the workbench 1 are fixedly installed with a fixed base 2, and the upper end of the fixed base 2 is provided with a fixing groove; a fixing ring 3 is fixedly installed at the lower end of the middle part of the workbench 1; six through-buffer holes are provided on the fixing ring 3, and through-buffer columns 301 are respectively installed in the buffer holes of the fixing ring 3; a spring is sleeved on the annular side wall of the buffer column 301, and the lower ends of the six buffer columns 301 are rotatably installed with a positioning ring 302; the positioning ring 302 and the fixing ring 3 are fixed. The side walls of the six buffer columns 301 are attached to each other, and a reset ring 303 is fixedly installed on the upper end of the six buffer columns 301, and a guide groove 304 is evenly opened on the side wall of the outer end of the reset ring 303. When the bearing retainer needs to be split, the inner ring of the bearing is first placed on the reset ring 303. At this time, the inner ring of the bearing and the reset ring 303 overlap up and down, and the reset ring 303 supports the bearing steadily. When the inner ring of the bearing is pressed down and disassembled, the retainer on the inner ring of the bearing will also move downward and detach for splitting. At this time, the reset ring 303 will also move downward. After the retainer on the bearing is pressed down and split, when the equipment for disassembling the retainer moves upward, the reset ring 303 will slowly lift up the inner ring retainer of the bearing.

[0025] Among them, mutually parallel sliding grooves 101 are respectively provided at both ends of the workbench 1, and a penetrating processing hole 102 is provided in the middle of the workbench 1, and the upper end of the inner side wall of the processing hole 102 is evenly fixedly installed with a guide bar 103, and the guide groove 304 on the reset ring 303 is slidably installed on the guide bar 103. When the reset ring 303 slides up and down, the guide groove 304 on the reset ring 303 is restricted by the guide bar 103, and the reset ring 303 can only slide up and down to prevent the reset ring 303 from tilting when sliding up and down, and the reset ring 303 cannot stably support the inner ring of the bearing, and a positioning block 104 is fixedly installed at the lower end of the inner side wall of the processing hole 102, and the fixing ring 3 is fixedly installed at the top of the positioning block 104, and the positioning block 104 firmly supports the fixing ring 3.

[0026] Among them, the fixing grooves of the two fixed bases 2 are respectively fixed with electric cylinders 201, and the opposite ends of the two electric cylinders 201 are respectively fixed with connecting blocks 202, and the opposite ends of the two connecting blocks 202 are respectively fixed with semicircular clamping plates 203, and the upper and lower ends of the clamping plates 203 are respectively fixed with anti-slip plates 204. During the disassembly of the retaining frame on the inner ring of the bearing, the electric cylinders 201 at both ends are used to push the two clamping plates 203 in opposite directions, and the two clamping plates are used to fix the retaining plates 204. The inner side wall of 203 clamps the outer side wall of the bearing, and the anti-slip plates 204 at the upper and lower ends are also attached to the edge of the bearing outer ring. The upper and lower anti-slip plates 204 cooperate with the clamping plate 203 to temporarily fix the bearing outer ring. When the bearing inner ring and the retaining frame are stamped downward for disassembly, the bearing outer ring is fixed and clamped and will not move when the retaining frame is split. At this time, the bearing inner ring and the retaining frame can be disassembled from the bearing. The bottom of the two anti-slip plates 204 at the lower end are fixedly installed with sliders 2 05, the slider 205 is slidably installed in the slide 101. When the clamping plate 203 slides left and right, the slider 205 is restricted by the slide 101, and the clamping plate 203 can only slide left and right to prevent the clamping plate 203 from tilting when sliding left and right. Two symmetrical fixed pins 206 are fixedly installed on the right side wall of the left clamping plate 203. When the two clamping plates 203 slide towards each other, the fixed pins 206 will be inserted into the fixed slots 207, temporarily holding the two clamping plates 203 together. The two fixing bases 201 are fixedly connected together, and four fixing slots 207 are provided on the left side wall of the right end clamping plate 203. The lower ends of the two side walls of the two fixed bases 2 are fixedly installed with stabilizing plates 208, and two penetrating bolts are rotatably inserted on the stabilizing plates 208. The bolts on the stabilizing plates 208 are rotatably inserted on the workbench 1 to fix the stabilizing plates 208 and the fixed base 2. When the fixed base 2 is touched, it will not move, so that the fixed base 2 can stably support the electric cylinder 201.

[0027] Example 2, based on Example 1, Figure 1 and Figure 4 As shown, the lower ends of the two side walls of the two fixed bases 2 are respectively fixedly installed with stabilizing plates 208, and two penetrating bolts are rotatably inserted on the stabilizing plates 208. The stabilizing plates 208 and the bolts are removed, and then the fixed base 2 is fixedly welded to the workbench 1 to stabilize the fixed base 2. In this way, the fixed base 2 will not shake when touched, avoiding the loosening of the bolts due to long-term use, and also saving the cost of parts.

[0028] The working principle of this embodiment: During use, when the bearing retainer needs to be split, the inner ring of the bearing is first placed on the reset ring 303. At this time, the inner ring of the bearing and the reset ring 303 overlap each other. When the inner ring of the bearing is pressed down for disassembly, the electric cylinders 201 at both ends are used to push the two clamping plates 203 in opposite directions, and the inner side walls of the two clamping plates 203 are used to clamp the side walls of the outer end of the bearing. At the same time, the anti-slip plates 204 at the upper and lower ends will also be attached to the edges of the outer ring of the bearing. The upper and lower anti-slip plates 204 cooperate with the clamping plates 203 to temporarily fix and clamp the outer ring of the bearing. When the inner ring of the bearing and the retainer are pressed downward for disassembly, the outer ring of the bearing will not move when the retainer is split due to the fixed clamping. At this time, the inner ring of the bearing can be removed from the bearing, and the retainer on the inner ring of the bearing will also be detached.
