[0002] During the processing, the bearing needs to be conveyed to the designated location by a conveyor belt for further processing. After reaching the designated location, it is clamped and removed from the conveyor belt by a clamp. Most of the existing clamps use cylinders to achieve clamping operations and control the clamping of the clamping arm. The cylinder not only requires an external air source, but also the clamping arm strength needs to adjust the air source size to control the clamping force of the clamping arm to avoid surface damage to the bearing. The operation process is relatively complicated and requires the laying of air pipes, which makes the entire equipment line messy and requires regular maintenance. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figures 1 to 5As shown, the linear bearing fixture of the utility model comprises a fixing member 1, a motor 2, a pushing member 3 and a mounting member 4. The motor 2 is mounted on the fixing member 1, while the pushing member 3 is mounted in the middle of the fixing member 1 and arranged on the motor 2, and the mounting member 4 is arranged at the lower end of the pushing member 3 and mounted in the middle of the fixing member 1. The motor 2 drives the pushing member 3 to move up and down, so that the clamping arm 6 on the clamping member 5 located on the mounting member 4 is deformed to clamp the two ends of the bearing.

[0025] The fixing member 1 is composed of a fixing plate 7 and side plates 8 arranged on both sides, and the other two sides of the fixing plate 7 are penetrated.

[0026] The middle of the fixing member 1 is hollowed out to form an activity chamber 9 , the motor 2 is mounted on the fixing member 1 , a rotating rod 10 is provided at the lower end of the motor 2 , a threaded portion 11 is provided on the rotating rod 10 , and the rotating rod 10 passes through the fixing member 1 and is placed in the activity chamber 9 .

[0027] The pusher 3 is mounted on the rotating rod 10, and a threaded hole 12 is provided in the middle of the pusher 3 to match the threaded portion 11. Pushing arms 13 are symmetrically arranged on both sides of the pusher 3, and a receiving area 14 is formed between the pushing arms 13, so that the mounting member 4 and the clamping member 5 are placed therein. An arc body 15 is provided at the lower end of the pushing arm 13, and the arc body 15 maintains tangential contact with the clamping arm 6, and the arc body 15 can better push the clamping arm 6 to clamp the bearing.

[0028] The mounting member 4 is installed in the activity chamber 9. The mounting member 4 is composed of a mounting arc portion 16 and a cylindrical portion 17. The diameter of the mounting arc portion 16 is larger than the diameter of the cylindrical portion 17. The mounting member 4 is connected to the inner wall of the fixing member 1 through a mounting shaft 18. The mounting member 4 is provided with a clamping member 5. The clamping member 5 is composed of an arc portion 19 and clamping arms 6 symmetrically arranged at both ends of the arc portion 19. A T-shaped block 20 is provided on the mounting arc portion 16. A T-shaped slot 21 matching the T-shaped block 20 is provided on the arc portion 19.

[0029] Since the diameter of the mounting arc portion 16 is greater than the diameter of the cylindrical portion 17 , a compression area 22 is formed between the arc portion 19 and the cylindrical portion 17 , so that when the clamping arm 6 clamps the bearing, both ends of the arc portion 19 can be forced into the compression area 22 .

[0030] A clamping area 23 is formed between the clamping arms 6, and the lower end of the push arm 13 is kept in contact with the clamping arm 6. A mounting opening 24 is provided in the middle of the arc portion 19, and the diameter of the mounting opening 24 matches the diameter of the mounting arc portion 16.

[0031] The clamping arm 6 is composed of an elastic section 25 and a clamping section 26. The elastic section 25 is arranged obliquely, and the clamping section 26 is arranged vertically. A through hole 27 and a load-bearing arc edge 28 are provided on the clamping section 26. The through hole 27 allows the middle of the bearing to communicate with the outside world, and the bearing will not fit the clamping section 26 and cannot be removed. The load-bearing arc edge 28 can cooperate with the clamping section 26 to support the bearing, so that the bearing will not fall off during the transfer process.

[0032] By pushing the arm 13 downward, the clamping arm 6 clamps the bearing. Even if the clamping force is large, the elastic section 25 will remain deformed without causing the clamping arm 6 to be subjected to a large force, thereby protecting the bearing surface from damage.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
