Description
Technical Field
The utility model belongs to the technical field of mechanical processing of elastic bodies, and particularly relates to a special tool clamp for threaded connection and self-locking prevention.
Background
The machining of the elastomer is a general procedure for producing the elastomer, and is a method for precisely machining the inner shape and the outer shape of the elastomer by using a lathe, so as to obtain the shape of the elastomer. At present, in the processing, according to the elastomers with different shapes, a tooling fixture which is suitable for the design is designed for precise processing.
For the partial bullet body, a special fixture for threaded connection is needed. The self-locking phenomenon often occurs when the tool clamp in threaded connection is used, and the elastomer is difficult or even impossible to detach after processing. The phenomenon is generated because the elastic body thread end face is required to be attached to the tool clamp thread end face during processing, the two end faces are attached too tightly under the action of cutting force after processing, the thread connection force is obviously increased than that before processing, self-locking is formed, and the disassembly is difficult or even impossible.
Disclosure of Invention
The utility model aims to provide a fixture for threaded connection and preventing self-locking, which solves the technical problems that the existing fixture for threaded connection often has the self-locking phenomenon when in use, and an elastomer is difficult or even impossible to disassemble after processing.
In order to achieve the above purpose, the specific technical scheme of the clamp for threaded connection and self-locking prevention is as follows:
the clamp for threaded connection and self-locking prevention is characterized by comprising a connecting ring 1 and a positioning plug 2; the inner hole of the connecting ring 1 is a threaded hole, the positioning plug 2 is cylindrical, and the outer surface of the positioning plug is provided with external threads; the outer side of the positioning plug 2 is provided with an annular positioning flange; the external thread of the positioning plug 2 is matched with the inner hole of the connecting ring 1, and the left end face of the positioning flange is attached to the right end face of the connecting ring 1.
Wherein, the outer wall of the connecting ring 1 is arranged in a step shape with thick left and thin right.
Wherein the diameter of the positioning flange is larger than the diameter of the inner hole of the connecting ring 1.
The clamp for threaded connection and self-locking prevention has the following advantages: the shape of the part during machining is guaranteed, and the phenomenon of difficult disassembly of the threaded tool clamp after machining is avoided.
Drawings
Fig. 1 is a schematic view of a structure of a clamp for threaded connection and self-locking prevention according to the present utility model.
Detailed Description
For a better understanding of the objects, structure and function of the present utility model, a clamp for threaded connection and anti-self locking will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the clamp for threaded connection and self-locking prevention comprises a connecting ring 1 and a positioning plug 2.
The inner hole of the connecting ring 1 is a threaded hole and is used for being connected with an external thread of an elastomer, the outer wall of the connecting ring is provided with a step shape with left thick and right thin, the positioning plug 2 is cylindrical, and the outer surface of the connecting ring is provided with an external thread; the outer side of the positioning plug 2 is provided with an annular positioning flange, and the diameter of the positioning flange is larger than the diameter of an inner hole of the connecting ring 1; the external thread of the positioning plug 2 is matched with the inner hole of the connecting ring 1, and the left end face of the positioning flange is attached to the right end face of the connecting ring 1.
The working process of the utility model comprises the following steps:
before installing the elastomer, the positioning plug 2 is in threaded connection with the connecting ring 1, the threads of the positioning plug 2 are completely screwed in, so that the step surface at the rear end of the threads of the positioning plug 2 is attached to the rear end surface of the connecting ring 1, and then the elastomer is installed. The connecting ring 1 is in threaded connection with the projectile body, and the threads are screwed into the bottom of the projectile body to be attached to the positioning plug 2. And then the installed clamp is installed on a three-jaw chuck of a lathe, the three-jaw chuck clamps the outer wall of the connecting ring 1, and the step surface of the outer wall of the connecting ring 1 is attached to the jaw end surface of the three-jaw chuck, so that the positioning and clamping requirements in machining are met. After machining, the elastic body, the connecting ring 1 and the positioning plug 2 are detached from the lathe, then the positioning plug 2 is detached, the interlocking with the elastic body is removed, and finally the connecting ring 1 is detached.
The fixture for threaded connection and self-locking prevention has the advantages of simple structure, low manufacturing cost and easiness in operation, ensures the shape of a part during machining, and avoids the difficult detachment of the tool fixture after machining; the connecting ring and the positioning plug thread size can be adjusted according to different thread sizes of the elastomer parts, so that the connecting ring and the positioning plug thread size can be used in mechanical processing of the elastomer with various size specifications, and the connecting ring and the positioning plug thread size have certain universality; the problem of the difficult dismantlement that the auto-lock leads to behind the processing of different threaded connection frock clamp has been solved, machining efficiency has been improved.
Although embodiments of the present utility model have been described in conjunction with the accompanying drawings, it will be apparent to those skilled in the art that several variations and modifications may be made without departing from the principles of the utility model, which are also considered to be within the scope of the utility model.
