Abstract
The utility model discloses an internal screw thread anchor clamps of protection part of finishing processing usefulness, including the cylinder, be provided with the external screw thread on the lateral wall of cylinder, the external screw thread cooperatees with the internal thread of treating the protection part, characterized by: the cylinder all is provided with the recess on two terminal surfaces of external screw thread, has seted up outer positive multilateral type recess on cylinder left side terminal surface, has seted up reserve logical groove on the right side terminal surface of cylinder, has seted up the installation that the internal thread was used for reserve anchor clamps on the inner wall that reserve logical groove, is provided with the interior positive multilateral type recess of little one number equally on the terminal surface of reserve anchor clamps and outer positive multilateral type recess homonymy, and one side in addition of reserve anchor clamps is provided with cross recess.
Description
Technical Field
The utility model relates to a part surface finishing processing technology field, in particular to internal screw thread anchor clamps of protection part that surface finishing processing was used.
Background
In the process of machining a mechanical part into a finished product from a blank, no matter casting, forging and machining, rough surfaces and surface defects with different degrees can be left on the machined surface of the part, such as edge flash, unevenness, collision scratch, edge deformity and the like, the quality and the performance of the part can be influenced, such as fatigue resistance, wear resistance and the like, and the precision, the performance and the service life of the assembled part can also be influenced.
The finishing process is a complex process that abrasive particles roll, scratch and scratch the surface of a part under certain pressure and relative speed, and the finishing process can damage a thread structure, so that the finishing process cannot be carried out on aviation parts with internal thread structures, such as nuts, movable joint nuts, blanking caps and the like. However, the female screw structure component is widely used in various parts of an engine, plays an important role in fastening, connection, and the like, and the surface quality thereof is not negligible, and if the female screw component can also be finished, the quality, performance, and other indexes of the female screw component are greatly improved. Therefore, how to finish the surface finishing of the internal thread parts with different shapes, sizes and finishing purposes without damaging the threads is the biggest difficulty of the surface finishing technology of the internal thread parts.
In the prior art, a clamp (patent number: ZL201420070255.0) for protecting internal threads of parts for surface finishing processing is disclosed, which belongs to the technical field of part surface finishing processing, and particularly relates to a clamp for protecting internal threads of parts for surface finishing processing. The clamp can ensure that the internal thread part of the part is effectively protected during finishing, prevent abrasive particles from damaging the internal thread, and realize the finishing of the internal thread part, and can be recycled, so that a large amount of cost is saved; the fixture is suitable for any part with an internal thread structure and needing finishing. The clamp of the utility model comprises a cylinder, wherein the outer side wall of the cylinder is provided with an external thread which is matched with the internal thread of the part to be protected; the end surface of the cylinder is provided with a groove.
The clamp still has some problems, such as that only a straight groove is arranged on the rotary clamp, the mode is single, and the clamp only considers the thread protection of a single size and cannot protect the threads with multiple diameters.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a protection part internal thread anchor clamps of processing usefulness are put forth one's own judgement to the surface.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a surperficial finishing processing usefulness protect internal screw thread anchor clamps of part, includes the cylinder, is provided with the external screw thread on the lateral wall of cylinder, the external screw thread cooperatees with the internal thread of waiting to protect the part, all is provided with the recess on two terminal surfaces of external screw thread at the cylinder, has seted up outer positive multilateral type recess on cylinder left side terminal surface, has seted up reserve logical groove on the right side terminal surface of cylinder, sets up the installation that the internal thread is used for reserve anchor clamps on the inner wall of reserve logical groove, is provided with the interior positive multilateral type recess of little one number on the terminal surface of reserve anchor clamps and outer positive multilateral type recess homonymy equally, and one side in addition of.
To sum up, the utility model discloses the beneficial effect who contrasts in prior art does: through improving current anchor clamps structure, be suitable for multiple rotary tool to the structure of using reserve anchor clamps can adapt to the thread protection of multiple diameter size.
Drawings
Fig. 1 is a schematic structural diagram of the embodiment.
Reference numerals: 1. a cylinder; 2. an external thread; 3. an outer regular polygonal groove; 4. a standby through groove; 5. an inner regular polygonal groove; 6. a cross-shaped groove.
Detailed Description
The following provides a more detailed description of the present invention with reference to the accompanying drawings.
The utility model provides a surface finishing processing usefulness protect internal screw thread anchor clamps of part, refer to fig. 1 and show, including cylinder 1, be provided with external screw thread 2 on the lateral wall of cylinder 1, external screw thread 2 cooperatees with the internal thread of waiting to protect the part, all is provided with the recess on cylinder 1 on two terminal surfaces of external screw thread 2, has seted up outer positive multilateral type recess on 1 left side terminal surface of cylinder, has seted up reserve logical groove 4 on the right side terminal surface of cylinder 1, has seted up the installation that the internal thread is used for reserve anchor clamps on the inner wall of reserve logical groove 4, is provided with little interior positive multilateral type recess of a little number on the terminal surface of reserve anchor clamps and outer positive multilateral type recess homonymy equally, and one side in addition of reserve anchor.
More preferably: the material of the cylinder 1 is polytetrafluoroethylene.
More preferably: a plurality of groups of cross-shaped grooves 6 are arranged on the end part of the standby fixture.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
