Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 and 2, an embodiment of an angularly adjustable positioning device of the present invention includes a machine body 1, a pushing member 2, a gear 4, a rack 3 and a mounting base 5, wherein the pushing member 2 is fixedly disposed on the machine body 1, so as to drive the rack 3 to move along a straight line direction by using the pushing member 2, and the pushing member 2 is preferably a cylinder in this embodiment. Meanwhile, in the application, the rack 3 is arranged along the vertical direction, so that the extending shaft of the pushing piece 2 moves downwards, and the rack 3 can be driven to move. Of course, the extending end of the pushing member 2 can be connected with the upper end part of the rack 3 so as to realize the driving and resetting of the rack 3; the extending end of the pushing member 2 can be not connected with the upper end part of the rack 3, and the rack 3 is driven to move only by the pushing member 2. In the embodiment, the protruding end of the pushing member 2 is connected with the upper end part of the rack 3 through the floating joint 21, so that the precision of the pushing member 2 driving the rack 3 to move can be increased.

The gear 4 is connected with the mounting base 5 through a gear shaft 41, and the gear 4 is meshed with the rack 3. When the rack 3 moves in the vertical direction under the driving of the pushing piece 2, the gear 4 can be driven to rotate by the meshing between the gear 4 and the rack 3. The mounting base 5 is then rotated relative to the machine body 1 by means of the gear shaft 41 keyed to the gear 4. The mounting base 5 is used for fixedly mounting a workpiece to be processed, so that the workpiece locked on the mounting base 5 is driven to rotate by the mounting base. Meanwhile, the gear shaft 41 is rotatably connected to the machine body 1 through a rolling bearing, so that resistance when the gear shaft 41 rotates with respect to the machine body 1 can be reduced.

The machine body 1 comprises a protruding part 11, a moving cavity is arranged through the protruding part 11 along the vertical direction, and the rack 3 is positioned in the moving cavity so as to facilitate the movement of the rack 3 relative to the protruding part 11. The side edge of the convex part 11 is provided with a groove which is communicated with the moving cavity, so that the gear teeth of the rack 3 can be exposed from the groove; while the gear 4 is mounted at the groove to facilitate the engagement of the gear 4 and the rack 3. The convex part 11 and the moving cavity are used for limiting the movement of the rack 3, so that the position precision of the rack 3 during movement can be increased, and the bending stress of the rack 3 during meshing of the gear 4 and the rack 3 can be reduced, thereby prolonging the service life of the rack 3. In the embodiment, the circular rack 3 is selected as the rack 3.

The machine body 1 is provided with a limiting assembly, the limiting assembly comprises a limiting block 111 and a limiting groove 33, and the limiting block 111 can be embedded in the limiting groove 33. In this embodiment, the limiting block 111 is disposed on the machine body 1, the limiting groove 33 is formed along the length direction of the rack 3, and the movement direction of the rack 3 can be limited by the cooperation of the limiting block 111 and the limiting groove 33, so that the position accuracy of the rack 3 during movement is improved. In this embodiment, the limiting block 111 is a roller, and the limiting block 111 is rotatably connected to the machine body 1. When the rack 3 moves in the vertical direction, the stopper 111 is embedded in the stopper groove 33, and the stopper 111 can rotate relative to the machine body 1 and the stopper groove 33, so that sliding friction between the stopper 111 and the stopper groove 33 can be converted into rolling friction, and resistance when the rack 3 moves is reduced.

The machine body 1 is provided with a bushing through which the rack 3 can pass, and the bushing is fixedly arranged inside the protruding part 11 in the embodiment. The bush is used to limit the direction of movement of the rack 3, so that the accuracy of the movement position of the rack 3 can be improved. Meanwhile, the rack 3 is slidably coupled with the protruding portion 11 through a bushing, so that resistance when the rack 3 moves can be reduced. The liner in this embodiment is preferably an oilless liner.

Both the upper end face and the lower end face of the rack 3 are provided with check rings 31, and the two check rings 31 are used for preventing the rack 3 from being separated from the machine body 1 so as to increase the stability of the positioning device during use. Further, a spring 32 is provided outside the rack 3, and the return of the rack 3 can be assisted by the spring 32. The spring 32 can abut against the retainer ring 31, and in this embodiment, the other end of the spring 32 abuts against the bushing, so that when the rack 3 moves downwards in the vertical direction, the retainer ring 31 at the upper end of the rack 3 moves downwards to approach the bushing, and the spring 32 is in a compressed state; when the rack 3 moves upward after the machining is completed, the spring 32 can convert its own elastic force into a pushing force, thereby assisting the reset of the rack 3.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
