Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, and particularly relates to a bearing fixture for new bearing production. Background Technique

[0002] During the bearing production process, a fixture is required to clamp the bearing, so as to facilitate processing such as grinding on both the inner and outer sides of the bearing. However, the general bearing fixture cannot have both stability and portability during use, so it is difficult to quickly perform different bearing processing operations at the same station, which is not conducive to the use of the device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bearing fixture for new bearing production to solve the problems raised in the above background technique.

[0004] A bearing fixture for new bearing production includes a support column: the support column is in a "T" shape, a fixing mechanism is arranged at the lower end of the support column, a self-locking mechanism is arranged at the upper end of the support column at equal angles, a clamping rod is slidably arranged in the support column at equal angles, the sliding end of the clamping rod is rectangular, and the end of the clamping rod outside the support column is arc-shaped.

[0005] Preferably, the fixing mechanism includes a suction cup and a control valve. A suction cup is arranged at the lower end of the support column, an air chamber communicated with the suction cup is opened at the lower end of the support column, and a control valve is arranged on the side of the air chamber.

[0006] When the device is in use, the support column will be fixed by using the suction cup, and then the gas in the suction cup can be released through the control valve to release the lock of the suction cup.

[0007] Preferably, a fixing column is arranged inside the air chamber, a piston rod is slidably arranged inside the fixing column, and a one-way valve is opened at the center of the piston rod.

[0008] When the piston rod slides in the fixing column, the space inside the fixing column will be reduced and the air pressure will increase, which will cause the air pressure inside the piston rod to increase, so that the one-way valve will open. At this time, the gas will flow out through the one-way valve to discharge the gas inside the fixing column.

[0009] Preferably, an air exchange port is opened at one end of the fixing column located inside the air chamber, a sphere is arranged inside the air exchange port, the sphere is engaged with the end of the air exchange port away from the piston rod, and a fixing spring is arranged inside the fixing column.

[0010] When the device is in use, when the piston rod is moved to increase the air pressure in the fixed column, the sphere will be pushed to move, so that the sphere blocks the ventilation port and closes it. Then, the gas in the fixed column is discharged. After that, the fixed spring will push the piston rod to move outwards. At the same time, the air pressure in the air chamber is greater than the air pressure in the fixed column, so the sphere will be pushed to move to open the ventilation port and restore the air pressure in the fixed column to the same as that in the suction cup. Then, the piston rod is pushed repeatedly until a large air pressure difference is formed between the inside of the suction cup and the outside world, so that the piston rod will not move outwards, thus fixing the device.

[0011] Preferably, the self-locking mechanism includes a worm and a worm wheel. The worm is rotatably arranged inside the support column, and the side of the worm is connected with the worm wheel.

[0012] Self-locking is achieved through the worm and the worm wheel, and the worm is rotated to drive the worm wheel to rotate.

[0013] Preferably, a connecting column is arranged at the upper end of the worm wheel, and a first bevel gear is arranged at the upper end of the connecting column. The worm wheel, the connecting column and the first bevel gear are rotatably arranged inside the support column.

[0014] Preferably, the side of the first bevel gear is meshed and connected with a second bevel gear, and a lead screw is connected to the side of the second bevel gear. The lead screw is rotatably arranged inside the support column.

[0015] Preferably, a clamping rod is threadedly connected to the outside of the lead screw.

[0016] When the worm wheel rotates, it will drive the connecting column and the first bevel gear to rotate. When the first bevel gear rotates, it will drive the second bevel gear to rotate, and the lead screw will rotate along with the first bevel gear. The movement of the clamping rod is controlled by the rotation of the lead screw, and the clamping of the inner and outer sides of the bearing is achieved through the clamping rod.

[0017] The beneficial effects of the present utility model are:

[0018] 1. When the device is in use, the suction cup is used to quickly fix the device. Then, the bearing is placed on the surface of the clamping rod or supported in suspension. Then, the clamping rod is driven to move by rotating the worm, so as to realize the clamping of the inner or outer side of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] During specific implementation: As Figures 1-5 shown, a bearing fixture for the production of a new type of bearing includes a support column 1: The support column 1 is in a "T" shape, a fixing mechanism is provided at the lower end of the support column 1, a self-locking mechanism is provided at the upper end of the support column 1 at equal angles, a clamping rod 14 is slidably arranged inside the support column 1 at equal angles, the sliding end of the clamping rod 14 is rectangular, and one end of the clamping rod 14 located outside the support column 1 is arc-shaped.

[0028] The fixing mechanism includes a suction cup 2 and a control valve 8. A suction cup 2 is provided at the lower end of the support column 1, an air chamber communicating with the suction cup 2 is opened at the lower end of the support column 1, and a control valve 8 is provided on the side of the air chamber.

[0029] When the device is in use, the support column 1 will be fixed by using the suction cup 2, and then the gas in the suction cup 2 can be released through the control valve 8, thereby releasing the lock of the suction cup 2.

[0030] A fixed column 3 is provided inside the air chamber, a piston rod 4 is slidably arranged inside the fixed column 3, and a one-way valve 5 is opened at the center of the piston rod 4.

[0031] When the piston rod 4 slides within the fixed column 3, the space inside the fixed column 3 will be reduced and the air pressure will increase. As a result, the air pressure inside the piston rod 4 will increase, causing the one-way valve 5 to open. At this time, the gas will flow out through the one-way valve 5, thereby discharging the gas inside the fixed column 3.

[0032] One end of the fixed column 3 located inside the air chamber is provided with a ventilation port. A sphere 7 is arranged inside the ventilation port, and the sphere 7 is engaged with the end of the ventilation port away from the piston rod 4. A fixed spring 6 is arranged inside the fixed column 3.

[0033] When the device is in use, when the piston rod 4 is moved to increase the air pressure inside the fixed column 3, the sphere 7 will be pushed to move, causing the sphere 7 to block and seal the ventilation port. Then, the gas inside the fixed column 3 will be discharged. After that, the fixed spring 6 will push the piston rod 4 to move outward. At the same time, the air pressure inside the air chamber is greater than the air pressure inside the fixed column 3, which will push the sphere 7 to move and open the ventilation port to restore the air pressure inside the fixed column 3 to be the same as the air pressure inside the suction cup 2. Then, the piston rod 4 is repeatedly pushed until a large air pressure difference is formed between the inside of the suction cup 2 and the outside, causing the piston rod 4 not to move outward, thereby fixing the device.

[0034] The self-locking mechanism includes a worm 9 and a worm gear 10. The worm 9 is rotatably arranged inside the support column 1, and the worm gear 10 is connected to the side of the worm 9.

[0035] Self-locking is achieved through the worm 9 and the worm gear 10. The worm 9 is rotated to drive the worm gear 10 to rotate.

[0036] The upper end of the worm gear 10 is provided with a connecting column 11, and the upper end of the connecting column 11 is provided with a first bevel gear 12. The worm gear 10, the connecting column 11, and the first bevel gear 12 are rotatably arranged inside the support column 1.

[0037] The side of the first bevel gear 12 is meshed and connected with a second bevel gear. The side of the second bevel gear is connected with a lead screw 13. The lead screw 13 is rotatably arranged inside the support column 1.

[0038] A clamping rod 14 is threadedly connected to the outside of the lead screw 13.

[0039] When the worm gear 10 rotates, it will drive the connecting column 11 and the first bevel gear 12 to rotate. When the first bevel gear 12 rotates, it will drive the second bevel gear to rotate, and the lead screw 13 will rotate along with the first bevel gear 12. The movement of the clamping rod 14 is controlled by the rotation of the lead screw 13, and the clamping on both sides of the inside and outside of the bearing is achieved through the clamping rod 14.
