Description

Technical Field

[0001] This application relates to the field of fixture technology, specifically a bearing outer ring fixture for machining needle roller bearings. Background Technology

[0002] Needle roller bearings are roller bearings with cylindrical rollers. The rollers are thin and long. Similar to traditional ball bearings, they rely on needles rolling between the inner and outer rings to reduce friction and achieve load-bearing and support functions. Meanwhile, the bearing outer ring fixture used for needle roller bearing machining is a process equipment used in the manufacturing process of needle roller bearings to fix and position the bearing outer ring. During the machining of needle roller bearings, the bearing outer ring needs to be machined by operations such as turning, grinding, and milling.

[0003] Many existing fixtures are designed solely to secure the outer ring of a bearing to prevent displacement during machining. However, when performing precision grinding, milling specific arcs or grooves on the inside of the bearing outer ring, the outer ring often needs to be able to rotate and adjust flexibly. Operators typically have to frequently disassemble and re-clamp the bearing outer ring, which reduces machining efficiency.

[0004] Therefore, it is necessary to provide a bearing outer ring fixture for machining needle roller bearings to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a bearing outer ring clamp for machining needle roller bearings, which achieves the effect of rotating and adjusting the bearing clamping process.

[0006] The technical solution adopted by this application to solve its technical problem is: a bearing outer ring fixture for machining needle roller bearings, including a fixture assembly, an adjustment component provided on the fixture assembly, the fixture assembly including a base, two sets of support plates fixedly installed on the base, a certain space between the two sets of support plates, an arc-shaped pressure cover hinged on the support plate, the arc-shaped pressure cover being adjustable to the support plate, the adjustment component including two sets of support rollers, the support rollers being mounted between the two sets of support plates, the support rollers being able to contact the bearing outer ring, and the support rollers being able to adjust the bearing outer ring.

[0007] Furthermore, a plurality of fixed caps are fixedly installed on one of the support rollers, the fixed caps being arranged in an array around the center of the support roller. A positioning seat is fixedly installed on the base, and a rotating rod is rotatably installed on the positioning seat. The other end of the rotating rod can be connected to a bearing on the support roller. A fixing plate is fixedly connected to the end of the rotating rod near the support roller. A locking pin is sleeved on the fixing plate. The locking pin can be adapted to the inside of the fixed cap and can pass through the fixing plate into the inside of the fixed cap.

[0008] Furthermore, an elastic element is provided on the outer side of the locking pin, and the elastic element can be fixedly connected to the fixing piece.

[0009] Furthermore, two sets of limiting rings are fixedly installed on the support roller, and the limiting rings can be distributed on both sides of the support roller, with the height of the limiting rings exceeding that of the support roller.

[0010] Furthermore, a fixing block is fixedly installed at one end of the support plate, and grooves are provided on both the arc-shaped pressure cap and the fixing block. A positioning rod is hinged to the bottom of the fixing block, and a nut is threaded onto the positioning rod.

[0011] Furthermore, the arc-shaped cap can be positioned close to the fixing block, the positioning rod can remain perpendicular to the fixing block, and the arc-shaped cap can be fixed to the fixing block by a nut.

[0012] Furthermore, the shape of the arc-shaped pressure cap is adapted to the outer contour of the bearing outer ring.

[0013] The beneficial effects of this application are:

[0014] This application provides a bearing outer ring clamp for machining needle roller bearings. Through the cooperation of two sets of support rollers and an arc-shaped pressure cover, the bearing can be clamped.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figures 1-3 As shown, this application provides a bearing outer ring fixture for machining needle roller bearings, including a fixture assembly 10 and an adjustment assembly 20 disposed inside the fixture assembly 10. The fixture assembly 10 is used to fix and position the bearing outer ring. During the machining of needle roller bearings, machining operations such as turning, grinding, and milling are required on the bearing outer ring. The adjustment assembly 20 is used to support and adjust the bearing fixed in the fixture assembly 10. Thus, the bearing can be fixed and adjusted inside the fixture assembly 10, and the bearing can be easily machined inside the fixture assembly 10, avoiding the need to change its position repeatedly.

[0025] The fixture assembly 10 includes a base 11 on which two sets of support plates 12 are fixedly mounted. There is a certain space between the support plates 12 to provide conditions for the installation of subsequent components and the placement of the bearing outer ring. Meanwhile, the adjustment assembly 20 includes two sets of support rollers 21, which are both mounted between the two sets of support plates 12. The bearing outer ring can be placed on the two sets of support rollers 21, so that the bearing outer ring can rotate flexibly on the support rollers 21. By utilizing the rotation characteristics of the support rollers 21, the bearing outer ring can be easily rotated and adjusted to facilitate machining operations at various angles. Furthermore, it eliminates the need for frequent disassembly and reclamping, greatly improving machining efficiency.

[0026] Meanwhile, an arc-shaped pressure cover 13 is hinged to the support plate 12. The arc-shaped pressure cover 13 can be adjusted onto the support plate 12. The shape of the arc-shaped pressure cover 13 is adapted to the outer contour of the bearing outer ring. When the bearing outer ring is placed on the two sets of support rollers 21, the arc-shaped pressure cover 13 can be adjusted onto the support plate 12 so that the arc-shaped pressure cover 13 can cover the bearing outer ring and achieve initial positioning.

[0027] A fixing block 16 is fixedly installed on one end of the support plate 12. Both the arc-shaped cover 13 and the fixing block 16 have grooves. When the arc-shaped cover 13 covers the support plate 12, the two sets of grooves can approach each other. A positioning rod 14 is hinged to the bottom of the fixing block 16. A nut 15 is threaded onto the positioning rod 14. When the arc-shaped cover 13 is close to the fixing block 16, the positioning rod 14 can be adjusted to keep it perpendicular to the fixing block 16. Then, the nut 15 is rotated downwards. The tightening force generated by the threaded engagement between the nut 15 and the positioning rod 14 will fix the arc-shaped cover 13 onto the fixing block 16, thereby achieving stable clamping of the bearing outer ring and ensuring that the bearing outer ring will not shift during processing.

[0028] Two sets of limiting rings 22 are fixedly installed on the support roller 21. The limiting rings 22 can be distributed on both sides of the support roller 21. At the same time, the height of the limiting rings 22 is higher than that of the support roller 21. When the outer ring of the bearing is placed on the support roller 21, the inner edge of the outer ring of the bearing will contact the limiting ring 22. At this time, the protruding limiting ring 22 enables the outer ring of the bearing to be limited and clamped on the support roller 21, preventing the outer ring of the bearing from moving laterally on the support roller 21.

[0029] Several sets of fixing caps 25 are fixedly installed on one set of support rollers 21. The fixing caps 25 are arranged in an array around the center of the support rollers 21. A positioning seat 23 is fixedly installed on the base 11. A rotating rod 24 is rotatably installed on the positioning seat 23. The end of the rotating rod 24 can be gripped. The other end of the rotating rod 24 can be connected to a bearing on the support roller 21 to ensure smooth rotation. At the same time, a fixing plate 26 is fixedly connected to the end of the rotating rod 24 near the support roller 21. A locking pin 27 is sleeved on the fixing plate 26. The locking pin 27 can be adapted to the inside of the fixing cap 25. At the same time, the locking pin 27 can pass through the fixing plate 26 and enter the inside of the fixing cap 25.

[0030] When it is necessary to fix the support roller 21 to prevent the outer ring of the clamped bearing from rotating inside the clamping assembly 10, the operator can rotate the rotating rod 24 to drive the fixing plate 26 and the locking pin 27 to rotate, so that the locking pin 27 is aligned with one of the positioning hole fixing caps 25. After the locking pin 27 is inserted into the positioning hole fixing cap 25, the rotational freedom of the support roller 21 is restricted, thereby achieving fixed positioning. Furthermore, through the cooperation of the rotating rod 24 and the locking pin 27, the fixed and rotatable states of the support roller 21 can be switched. The operator does not need to use complicated tools or cumbersome steps, which greatly improves the convenience and efficiency of operation.

[0031] Meanwhile, an elastic element 28 is provided on the outer side of the locking pin 27. The elastic element 28 can be fixedly connected to the fixing plate 26. The elastic element 28 can output elastic force, so that the locking pin 27 can be pushed into the fixing cap 25, preventing the locking pin 27 from accidentally coming out due to vibration or other factors during the processing, thereby improving the stability of the support roller 21 when it is fixed.

[0032] When the outer ring of the bearing needs to be readjusted, the operator pulls the locking pin 27 outward, so that the locking pin 27 can disengage from the inside of the fixing cap 25. At this time, the support roller 21 can rotate freely, which facilitates the position adjustment of the outer ring of the bearing.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
