Detailed Description

The following describes embodiments of the utility model in detail, but the utility model may be practiced in a variety of different ways, as defined and covered by the claims.

As one aspect of the present utility model, there is provided a bearing jig comprising: the novel clamping ring comprises a seat body, a pull rod 1, a clamping ring 2, a spring 3 and a locking nut 4, wherein an accommodating cavity is formed in the seat body, the top of the pull rod 1 is connected with the bottom of the clamping ring 2, a through hole 5 communicated with the accommodating cavity is formed in the bottom of the seat body, a guide groove 6 is formed in the pull rod 1, a guide protrusion 7 matched with the guide groove 6 is arranged in the through hole 5, the pull rod 1 is arranged in the through hole in a penetrating mode, a threaded portion 8 is arranged at the lower end of the pull rod 1, the locking nut 4 is connected with the threaded portion 8, the spring 3 is sleeved on the pull rod 1, and the spring 3 is located in the accommodating cavity and below the clamping ring 2. Preferably, a thrust ball bearing 9 is provided between the lock nut 4 and the housing, so that the rotating lock nut 4 can be operated better.

Preferably, a vertical slit 10 is formed in the circumferential direction of the clamping ring 2, a first conical surface 11 is formed on the outer wall of the clamping ring 2, and a second conical surface 12 matched with the first conical surface 11 is formed on the inner wall of the accommodating cavity. Preferably, a circular hole 13 is formed at the lower end of the vertical slit 10. The vertical slits 10 and the circular holes 13 provide a deformation gap during the downward movement of the clamp ring 2. The first conical surface 11 has an inclination angle of 10 degrees, and if the inclination angle is too large, the nozzle holder cannot be easily pulled into the annular housing 16, so that the purpose of clamping cannot be achieved. When clamping is required, by tightening the lock nut 4, the spring 3 is compressed, the pull rod 1 moves downward, the clamp ring 2 is pulled downward, and the shrinkage opening at the upper part of the clamp ring 2 is shrunk inwards due to the inclination angle, thereby clamping the bearing ring 23. When it is desired to loosen, the lock nut 4 is unscrewed and the clamping ring 2 rebounds to loosen the upper constriction, thereby loosening the bearing ring 23.

Preferably, a stepped hole 14 is formed in the bottom of the clamping ring 2, a circular stepped portion 15 is formed at the top of the pull rod 1, and the circular stepped portion 15 is disposed in the stepped hole 14 and connected with the stepped hole 14. For example, the circular stepped portion 15 is welded to the stepped hole 14.

Preferably, the base body comprises an annular outer shell 16 and a hexagonal base 17, and the lower end of the annular outer shell 16 is connected with the upper end of the hexagonal base 17. For example, both may be welded.

Preferably, the bearing fixture further comprises a mounting frame, the mounting frame comprises a mounting plate 18, a supporting rod 19 and a bottom plate 20 which are sequentially connected from top to bottom, a hexagonal hole 21 is formed in the mounting plate 18, and the hexagonal base 17 is mounted in the hexagonal hole 21 through a jackscrew 22.

Referring to fig. 1 to 5, the clamping object of the present utility model is a bearing ring 23 with external threads on the outer wall, which is used for connecting with a power hammer and a power valve in a downhole torque impact tool, and of course, the present utility model can also be used for clamping a conventional bearing ring without external threads. In the present utility model, the clip 2 is fitted into the annular housing 16 by a clearance fit, and is capable of sliding in the annular housing 16.

The spring 3 is sleeved on the pull rod 1, the thrust ball bearing 9 and the hexagonal base 17 are placed in the hexagonal base slot through clearance fit, and the lock nut 4 is connected to the tail end of the pull rod 1 through threads. The main body part of the whole clamp is placed in the hexagonal hole 21 through clearance fit and is tightly pressed and fixed through the jackscrew 22.

The bearing ring 23 is placed in the clamp ring 2, when clamping is needed, the clamp ring 2 is elastically contracted and deformed under the matched structure of the first conical surface 11 and the second conical surface 12 by locking the lock nut 4 and compressing the pull-down rod 1 by the spring 3, so that the bearing ring 23 is clamped, and the fixing effect is achieved. When the clamping ring 2 needs to be loosened, the locking nut 4 is loosened, the spring 3 is rebounded, and the shrinkage opening at the upper part is rebounded by the clamping ring, so that the bearing ring 23 is loosened.

Due to the adoption of the technical scheme, the clamping ring 2, the pull rod 1 and the locking nut 4 can be used for clamping the bearing ring 23, so that the bearing ring 23 is fixed, and the novel clamping ring has the characteristics of simple structure and convenience in operation.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
