Description

Technical Field

[0001] This utility model relates to the field of bearing roller testing technology, and in particular to a bearing roller roundness testing device. Background Technology

[0002] Cylindrical roller and tapered roller bearings are both separable bearings, with raceways on both the inner and outer rings. During use, the rollers rotate within these raceways. Therefore, the roundness of the outer circumference of the rollers is crucial to the quality of the manufactured bearings. Substandard roller quality directly shortens the bearing's service life.

[0003] After the bearing rollers are machined, their roundness must first be checked to screen out those that do not meet quality standards, thus extending the bearing's service life. Existing bearing roller roundness testing devices typically use a roller positioner with a pin and testing assembly. During testing, one end face of the bearing roller is placed on a support surface, and three pins are used to clamp and limit the roller's outer circumference. Two pins are fixed, while the third pin uses a dial indicator or micrometer indicator. The outer circumferential parameters of the bearing roller can be obtained by reading the dial indicator or micrometer indicator.

[0004] Because bearing rollers come in different sizes, single-size roller positioners often cannot meet the testing requirements. When the axial length of the bearing roller is large, i.e. when it has a narrow and long structure, the stability of the roller clamping will be poor, affecting the test results.

[0005] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

The support seat 46 forms a support surface 461. A space for installing the workpiece 5 is formed between the support seat 46 and the connecting block 43. A ejector pin 44 is threaded to the connecting block 43. The ejector pin 44 can be threadedly adjusted in a direction perpendicular to the support surface 461. By rotating and adjusting the ejector pin 44, its end can abut against one end of the workpiece 5, thus pressing the workpiece 5 in place. The support surface 461 forms a tight fit. Adjustable ejector pins 21 and 22 are also installed on the bracket 2. Ejector pins 21 and 22 can be adjusted to abut against the outer periphery of the workpiece 5, achieving a limiting installation of the workpiece 5. A detection component 3 is also installed on the bracket 2 at the other end opposite to ejector pin 21 and towards ejector pin 21. The detection component 3 can adjust the probe 32 to abut against the outer periphery of the workpiece 5, enabling the detection of the roundness of the outer periphery of the workpiece 5. The probe 32 is a dial indicator or micrometer; the reading of the dial indicator or micrometer indicates the outer periphery parameters of the bearing roller. The entire device has high structural stability, is easy to adjust, and can stably clamp the workpiece 5 to be tested, improving detection accuracy and ensuring product quality.

[0028] Reference Figure 2As shown, workpiece 5 is a cylindrical or tapered roller of a bearing, with a cylindrical or conical shape. The main body of bracket 2 has an arc-shaped structure. Fixing part 1 24 and fixing part 3 28 are fixedly connected to both ends of bracket 2, and fixing part 1 24 and fixing part 3 28 are coaxially opposite each other. Fixing part 2 25 is fixedly connected to the middle of bracket 2 via connecting part 27. Through holes are opened in the center of fixing part 1 24, fixing part 3 28 and fixing part 2 25, and fastening bolts 29 are threaded to the outer periphery of each. Movable part 1 241 and movable part 251 are slidably installed in the inner periphery of the through holes on fixing part 1 24 and fixing part 2 25, respectively.

Move towards the workpiece so that ejector pin 1 21 and ejector pin 22 can respectively abut against the outer periphery of workpiece 5 for limiting. Then, by rotating and adjusting the fastening bolt 29, movable part 1 241 and movable part 251 can be locked to the inner periphery of fixed part 1 24 and fixed part 25 respectively, realizing the limiting installation. The detection component 3 mainly includes a clamping rod 31 and probes 32 and a scale plate respectively installed at both ends of the clamping rod 31.

The probe 32 is a dial indicator or a dial gauge, which is fixedly installed at the end of the clamping rod 31 facing the workpiece 5. By sliding and adjusting the clamping rod 31, the end of the probe 32 can abut against the outer periphery of the workpiece 5 to detect the outer periphery roundness of the workpiece 5 and obtain the outer periphery parameters of the bearing roller.

[0029] Reference Figure 4As shown, the clamping assembly 4 mainly includes a connecting rod 41, an arc-shaped frame 42, and a connecting block 43. The arc-shaped frame 42 is arc-shaped and fixedly installed between the connecting rod 41 and the connecting block 43.

A support seat 46 is fixedly installed on the side of the adjusting screw 45 facing the third ejector pin 44, forming a support surface 461. A workpiece 5 can be installed between the support seat 46 and the third ejector pin 44. By rotating and adjusting the third ejector pin 44, its end abuts against one end of the workpiece 5, so that the other end of the workpiece 5 is tightly fitted. The support surface 461 on the support base 46 can form a stable clamping of the workpiece in the axial direction; a through connecting hole 23 is opened at the center of the bracket 2 and in the direction of the probe 32. The connecting rod 41 passes through the connecting hole 23 and can be slidably adjusted in the direction of the connecting hole 23. A fastening bolt is threaded on the outside of the bracket 2 relative to the installation position of the connecting rod 41.

[0030] When workpiece 5 needs to be inspected, it must first be stably clamped. First, according to the specific dimensions of workpiece 5, adjust the relative position of the connecting rod 41 and the bracket 2 by sliding adjustment and lock it with fastening bolts. Then, rotate the adjusting screw 45 connected to the center thread of the adjusting rod 41 to adjust the distance between the support base 46 and the connecting block 43 to a suitable distance. Then, place workpiece 5 between the support base 46 and the connecting block 43 so that one end of workpiece 5 abuts against the support surface 461 on the support base 46. Then, adjust the ejector pins 21 and 22 movably mounted on the bracket 2 so that they abut against the outer periphery of workpiece 5 to form a limiting support. Finally, adjust the inner thread of the connecting block 43 by rotating the screw. The ejector pin 344 is connected so that its end abuts against one end of the workpiece 5, which can form an axial pressure on the workpiece 5, so that the workpiece 5 can fit tightly against the support surface 461 on the support base 46; finally, the clamping rod 31 in the detection assembly 3 is slidably adjusted so that the end of the probe 32 abuts against the outer periphery of the workpiece 5 to detect the outer circumference roundness of the workpiece 5 and obtain the outer circumference parameters of the bearing roller; after the first position point detection is completed, the direction of ejector pin 344 is adjusted so that it no longer abuts against the workpiece, the workpiece 5 is rotated to a suitable position, and then ejector pin 34 is adjusted to abut against the workpiece 5 again, and the detection is performed again. The operation can be repeated. By improving the clamping stability of the workpiece 5, the detection accuracy of the workpiece 5 can be improved.

[0031] Reference Figure 2 and Figure 3As shown, a protrusion 11 is integrally connected to the upper end of the base 1, and a through hole 111 is provided on the protrusion 11. A cylindrical part 26 is integrally connected to the lower end of the bracket 2, and a through hole 261 is provided in the center of the cylindrical part 26.
