[0024] 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.

[0025] like Figures 1 to 7 As shown, the linear bearing flange positioning fixture of the utility model comprises a base 1, a positioning column 2 and a rotating member 3. The positioning column 2 is arranged on the base 1, and the rotating member 3 is arranged in the middle of the positioning column 2.

[0026] An inner ring 5 is provided in the middle of the bearing flange 4, and four fixing holes 6 are provided around the inner ring 5. The inner ring 5 of the bearing flange 4 is changed according to the diameter of the installed shaft, so different positioning fixtures are required, but when multiple fixtures are used, there are too many fixtures, which causes waste and is not suitable for the positioning of most bearing flanges 4.

[0027] A plurality of positioning rods 7 are further provided on the base 1 . A second threaded portion 8 is provided at the lower end of the positioning rod 7 . A second threaded hole 9 matching with the second threaded portion 8 is provided on the base 1 .

[0028] A fixing column 10 is disposed on the base 1 , and a first threaded hole 11 is disposed in the middle of the fixing column 10 . The fixing column 10 and the positioning column 2 can be fixed from the bottom surface of the base 1 by bolts 12 .

[0029] The middle of the positioning column 2 is hollowed out to form an activity chamber 13, and the fixed column 10 is arranged in the activity chamber 13. The rotating member 3 is arranged in the activity chamber 13, and the rotating member 3 is composed of a hexagonal body 14 and a rod body 15. The lower end of the rod body 15 is provided with a first threaded portion 16 that matches the first threaded hole 11. Rotating the hexagonal body 14 of the rotating member 3 can make the first threaded portion 16 rotate in the first threaded hole 11, so that the rod body 15 moves downward while rotating, thereby driving the traction member 17 to pull the fastener 18.

[0030] The positioning column 2 is provided with a plurality of openings 19 and movable grooves 20, the openings 19 are connected to the movable grooves 20, and the diameter of the rod body 15 is smaller than the diameter of the movable chamber 13. The width of the movable groove 20 is greater than the width of the fastener 18. A fastener 18 is provided in the movable groove 20, and a protrusion 21 is provided on the fastener 18 and is arranged in the opening 19. The fastener 18 and the rod body 15 are connected by a traction member 17, and the traction member 17 is a rope body that can be retracted under force. A reset member 22 is provided on the traction member 17, and the reset member 22 is a spring. The reset member 22 is arranged in the movable groove 20 and is located between the inner wall of the movable groove 20 and the fastener 18.

[0031] A first mounting hole 23 is provided between the fastener 18 and the raised portion 21, one end of the traction member 17 is placed in the first mounting hole 23 and fixed by a bolt 12, a second mounting hole 24 through which the traction member 17 passes is provided on the positioning column 2, a third mounting hole 25 is provided on the rotating member 3, the other end of the traction member 17 is placed in the third mounting hole 25 and fixed by a bolt 12.

[0032] When the bearing flange 4 needs to be placed, the rotating member 3 can be rotated so that the traction member 17 is pulled, driving the fastener 18 to enter the movable groove 20, and the protrusion 21 enters the opening 19, keeping the arc surface 26 on the protrusion 21 tangent to the outer wall of the positioning column 2, so that the inner ring 5 of the bearing flange 4 is placed on the positioning column 2, and the fixing hole 6 is placed on the positioning rod 7. When fixing the bearing flange 4, the rotating member 3 is rotated in the opposite direction, and the fastener 18 and the protrusion 21 are pushed under the elastic force of the reset member 22, and the friction force is maintained between the protrusion 21 and the inner ring 5, so that the bearing flanges 4 are fixed in multiple places, which is convenient for grinding the side of the bearing flange 4 later.

[0033] The above description is only a preferred embodiment of the present invention and is 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.
