Description

Technical Field

[0001] This utility model belongs to the field of tapered roller machining technology, and in particular relates to a fixture for machining tapered rollers for bearings. Background Technology

[0002] A tapered roller is a rolling element with a tapered surface. Both its inner and outer raceways are tapered, and the apex of the tapered surface of the roller intersects at a point on the bearing axis. Tapered rollers require fixing and grinding during production, thus requiring the use of a fixing fixture. Publication number CN209614878U discloses a multi-station movable fixture for tapered roller production, including a base plate and a telescopic cylinder. A limit plate is fixed to one side of the upper part of the base plate, and a clamping plate is provided at the upper end of the limit plate. The telescopic cylinder is fixed to the upper middle part of the base plate. A fixing plate is provided above the mounting platform, and a groove is formed on one side of the upper end of the fixing plate. A limiting groove is formed in the middle of the upper end of the fixing plate, and a clamping block is installed inside the limiting groove. A support column is fixed above the movable plate, and a movable cavity is formed inside the support column. A movable block is connected above the spring, and a connecting rod is connected above the movable block. This multi-station movable fixture for tapered roller manufacturing can easily install tapered rollers and can clamp multiple bearings simultaneously to inspect the tapered rollers inside different bearings. In addition, the height of the fixture is adjustable, making it suitable for a wide range of applications.

[0003] However, existing technologies have some problems: when existing fixtures fix tapered rollers, they cannot be adjusted according to the taper of the rollers, which makes the rollers not securely fixed during the production and processing process, causing them to wobble and affecting the smoothness of the rollers after grinding. Therefore, we propose a fixture for machining tapered rollers for bearings. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a fixture for machining tapered rollers for bearings. Through a rotatable fixing clamp and a locking assembly, the fixing clamp can be adjusted according to the roller taper, thereby making the roller more securely fixed.

[0005] This utility model is implemented as follows: a fixture for machining tapered rollers for bearings includes a mounting base, a support arm fixedly connected to the mounting base, a connecting seat slidably connected to the support arm, two sets of connecting arms rotatably connected to the connecting seat, a driving assembly disposed inside the connecting seat, the driving assembly being used to drive the connecting arms to rotate, a gripper fixedly connected to one end of the connecting arm, a fixing clamp rotatably connected to one end of the gripper, and a locking assembly disposed on the gripper to restrict the rotation of the fixing clamp.

[0006] Optionally, a slide rail is provided on one side of the support arm, the connecting seat is slidably connected in the slide rail, and a threaded rod is rotatably connected in the slide rail, the threaded rod being threadedly connected to the connecting seat.

[0007] Optionally, a motor is fixedly connected to the support arm, and the threaded rod is fixedly connected to the output end of the motor. The motor is used to drive the threaded rod to rotate.

[0008] Optionally, the drive assembly includes a hydraulic rod, which is fixedly connected to the connecting seat, and a connecting rod is fixedly connected to the movable end of the hydraulic rod.

[0009] Optionally, two sets of transmission rods are rotatably connected to the connecting rod, and the two sets of transmission rods are respectively rotatably connected to two sets of connecting arms.

[0010] Optionally, a groove is provided on one side of the gripper, a rotating shaft is fixedly connected in the groove, a fixed seat is fixedly connected on the rotating shaft, and the clamp is fixedly connected to the fixed seat.

[0011] Optionally, the fixing clip is provided in two sets, and the two sets of fixing clips are symmetrically fixedly connected to the fixing base. The fixing clip is arc-shaped and a rubber pad is fixedly connected to the fixing clip.

[0012] Optionally, the locking assembly includes a locking knob, the gripper has a threaded hole, the locking knob is threaded into the threaded hole, the gripper has a sliding groove below the threaded hole, a locking block is slidably connected in the sliding groove, and the locking block is rotatably connected to the locking knob.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a rotatable fixing clamp and a locking component. When the two sets of connecting arms clamp synchronously, the gripper and the fixing clamp will also retract accordingly. When the fixing clamp contacts the tapered roller, the fixing clamp will rotate due to the curved surface of the cone, so that the fixing clamp tilts and fits against the surface of the tapered roller. After the fixing clamp fits against the surface of the tapered roller, tightening the locking knob will cause the locking knob to move the locking block downward, thereby fixing the rotating shaft and preventing the fixing clamp from rotating. This allows the clamp to fix tapered rollers of the current taper. When fixing tapered rollers of other specifications, loosening the locking knob will allow the rotating shaft to rotate, recalibrating the angle of the fixing clamp to fit against the surface of the tapered roller, and then tightening the locking knob. The locking component allows this clamp to fix tapered rollers of different tapers.

[0015] 2. This utility model can drive the threaded rod to rotate by starting the motor. After the threaded rod rotates, it will drive the connecting seat to slide in the slide, thereby changing the height of the connecting seat and thus changing the height of the fixing clamp, so that this clamp can fix tapered rollers of different lengths.

[0016] 3. This utility model has two sets of arc-shaped fixing clips on the fixing base. The two sets of fixing clips can better compress the tapered roller, making the tapered roller more firmly fixed. At the same time, the arc-shaped design of the fixing clips can make the fixing clips fit the tapered rollers better, increasing the contact area and thus increasing the friction between the fixing clips and the tapered rollers, making the fixing more secure. Similarly, the rubber pads fixed on the surface of the fixing clips can also increase the friction. At the same time, the rubber pads can also prevent the fixing clips from scratching the surface of the tapered rollers, thus improving product quality.

[0026] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] like Figures 1 to 7 As shown in the figure, the present invention provides a fixture for machining tapered rollers for bearings, including a mounting base 1. The mounting base 1 is rectangular and made of stainless steel. The main function of the mounting base 1 is to mount the fixture on the machine.

[0028] Furthermore, a support arm 2 is fixedly connected to the mounting base 1. The support arm 2 is also made of stainless steel, and a connecting seat 3 is slidably connected to the support arm 2.

[0029] Furthermore, a slide rail is provided on one side of the support arm 2, and the connecting seat 3 is slidably connected in the slide rail. A threaded rod 9 is rotatably connected in the slide rail. The threaded rod 9 is threadedly connected to the connecting seat 3. A motor 10 is fixedly connected to the support arm 2. The threaded rod 9 is fixedly connected to the output end of the motor 10. The motor 10 is used to drive the threaded rod 9 to rotate.

[0030] Specifically, when the motor 10 starts, it drives the threaded rod 9 to rotate. After the threaded rod 9 rotates, it will drive the connecting seat 3 to slide in the slide, thereby changing the height of the connecting seat 3, which in turn changes the height of the fixing clamp 7, so that the clamp can fix tapered rollers of different lengths.

[0031] Furthermore, two sets of connecting arms 4 are rotatably connected to the connecting base 3, and a driving component 5 is provided inside the connecting base 3. The driving component 5 is used to drive the connecting arms 4 to rotate.

[0032] Specifically, the drive assembly 5 includes a hydraulic rod 501, which is fixedly connected to the connecting seat 3, and a connecting rod 502 is fixedly connected to the movable end of the hydraulic rod 501.

[0033] Furthermore, two sets of transmission rods 503 are rotatably connected to the connecting rod 502, and the two sets of transmission rods 503 are rotatably connected to the two sets of connecting arms 4 respectively.

[0034] Specifically, the extension and retraction of the hydraulic rod 501 drives the connecting rod 502 to move, and the movement of the connecting rod 502 drives the two sets of transmission rods 503 to rotate. The two sets of transmission rods 503 respectively drive the two sets of connecting arms 4 to rotate, so that the two sets of connecting arms 4 clamp or loosen synchronously. This ensures that when fixing the tapered roller, the force on both sides of the tapered roller is uniform and there will be no deviation, thus avoiding different surface smoothness of the tapered roller during grinding.

[0035] Furthermore, a gripper 6 is fixedly connected to one end of the connecting arm 4, and a fixing clamp 7 is rotatably connected to one end of the gripper 6. A groove is provided on one side of the gripper 6, and a rotating shaft 11 is fixedly connected in the groove. A fixing seat 12 is fixedly connected to the rotating shaft 11, and the fixing clamp 7 is fixedly connected to the fixing seat 12.

[0036] Specifically, when the two sets of connecting arms 4 clamp simultaneously, the gripper 6 and the fixing clamp 7 will also retract accordingly. When the fixing clamp 7 contacts the tapered roller, the fixing clamp 7 will rotate due to the curved surface of the cone, thereby causing the fixing clamp 7 to tilt and fit against the surface of the tapered roller.

[0037] Furthermore, the fixing clip 7 is provided in two sets, and the two sets of fixing clips 7 are symmetrically fixedly connected to the fixing base 12. The fixing clip 7 is arc-shaped, and a rubber pad 13 is fixedly connected to the fixing clip 7.

[0038] Specifically, the two sets of fixing clips 7 can better compress the tapered rollers, making the tapered rollers more securely fixed. At the same time, the arc-shaped design of the fixing clips 7 allows them to fit the tapered rollers more closely, increasing the contact area and thus increasing the friction between the fixing clips 7 and the tapered rollers, making the fixation more secure. Similarly, the rubber pads 13 fixed to the surface of the fixing clips 7 can also increase the friction. At the same time, the rubber pads 13 can also prevent the fixing clips 7 from scratching the surface of the tapered rollers, thus improving product quality.

[0039] Furthermore, the gripper 6 is provided with a locking component 8, which restricts the rotation of the fixing clamp 7. The locking component 8 includes a locking knob 801. The gripper 6 has a threaded hole, and the locking knob 801 is threaded into the threaded hole. A sliding groove is provided below the threaded hole of the gripper 6, and a locking block 802 is slidably connected in the sliding groove. The locking block 802 is rotatably connected to the locking knob 801.

[0040] Specifically, after the fixing clamp 7 is in contact with the surface of the tapered roller, tightening the locking knob 801 causes the locking knob 801 to move the locking block 802 downward, thereby fixing the rotating shaft 11. The fixing clamp 7 cannot rotate, which allows the fixture to fix the tapered roller of the current taper. When fixing cylindrical rollers of other specifications, loosen the locking knob 801 so that the rotating shaft 11 can rotate, recalibrate the angle of the fixing clamp 7 so that it is in contact with the surface of the tapered roller, and then tighten the locking knob 801. The locking assembly 8 allows this fixture to fix tapered rollers of different tapers.

[0041] The working principle of this utility model is as follows:

[0042] This utility model is equipped with a rotatable fixing clamp 7 and a locking component 8. When the two sets of connecting arms 4 clamp simultaneously, the gripper 6 and the fixing clamp 7 will also retract. When the fixing clamp 7 contacts the tapered roller, the fixing clamp 7 will rotate due to the curved surface of the cone, so that the fixing clamp 7 tilts and fits against the surface of the tapered roller. After the fixing clamp 7 fits against the surface of the tapered roller, tightening the locking knob 801 causes the locking knob 801 to drive the locking block 802 to move downward, thereby fixing the rotating shaft 11. The fixing clamp 7 cannot rotate, so that the clamp can fix the tapered roller of the current taper. When fixing other specifications of cylindrical rollers, loosen the locking knob 801 so that the rotating shaft 11 can rotate, recalibrate the angle of the fixing clamp 7 so that it fits against the surface of the tapered roller, and then tighten the locking knob 801. The locking component 8 allows this clamp to fix tapered rollers of different tapers.

[0043] This utility model can start the motor 10 to drive the threaded rod 9 to rotate. After the threaded rod 9 rotates, it will drive the connecting seat 3 to slide in the slide, thereby changing the height of the connecting seat 3, which in turn changes the height of the fixing clamp 7, so that this clamp can fix tapered rollers of different lengths.

[0044] This utility model provides two sets of arc-shaped fixing clips 7 on the fixing base 12. The two sets of fixing clips 7 can better exert extrusion force on the tapered roller, making the tapered roller more firmly fixed. At the same time, the arc-shaped design of the fixing clips 7 allows the fixing clips 7 to fit the tapered roller more closely, increasing the contact area and thus increasing the friction between the fixing clips 7 and the tapered roller, making the fixation more secure. Similarly, the rubber pads 13 fixed on the surface of the fixing clips 7 can also increase the friction. At the same time, the rubber pads 13 can also prevent the fixing clips 7 from scratching the surface of the tapered roller, thus improving product quality.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
