Description
Technical Field
The invention belongs to the field of valve machining, and relates to a clamp for clamping rotary thin-wall parts.
Background
With the continuous development of scientific technology and new processing equipment, the technical means such as new technology and new method are adopted to improve the production efficiency of products, reduce the cost and ensure the product quality, and the method becomes an important strategy for enterprises to obtain profits and conspire to develop for a long time. In the field of aerospace valves, rotary thin-wall parts are common parts in valve products. There are a number of features where the body structure is thin walled and the profile needs to be machined by milling.
The rotary thin-wall parts are characterized by thin outer wall and special shape. Several problems will occur when clamping on a turning and milling combined machining center machine tool: firstly, the thin wall part is clamped in a chuck to form a cantilever beam, so that the part is easy to deform during processing and the requirement of part jumping cannot be met; secondly, when the thin wall is clamped, the part clamp is easy to deform when the chuck is used for clamping.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a clamp for clamping rotary thin-wall parts, which is based on the design of a deformed steel claw and a clamping frame and is based on three-claw self-centering, the clamping is convenient and the part cannot be deformed at the clamping position; the extension length of the part is reduced, the rigidity of a part rod to be processed is enhanced, and the problem of jumping and over-tolerance of the part is avoided; and meanwhile, axial positioning is designed, so that the problem that the cutter drives the part to move is effectively avoided. The invention improves the efficiency of clamping the rotary thin-wall parts and simultaneously avoids the deformation of the parts caused by the problem of clamping, so the invention provides a key means for improving the processing efficiency of the rotary thin-wall parts in a turn-milling composite processing center and ensuring the product quality.
In order to achieve the purpose, the invention adopts the following technical scheme:
a clamp for clamping rotary thin-wall parts comprises a deformed steel claw and a steel clamping frame, wherein a deformed steel claw thread is arranged at one end of the deformed steel claw and is in threaded fit with the steel clamping frame thread arranged at one end of the steel clamping frame; the other end of the deformed steel bar claw is of a hexagonal structure and is provided with three 120-degree openings, and the deformed steel bar claw is provided with steps.
Preferably, the steel clip frame is provided with a chamfer in an inner hole, and the thread steel claw is provided with a chamfer in a matching manner.
Preferably, the angle of the inner hole of the steel clamping frame is smaller than the chamfer angle of the threaded steel claw.
Preferably, a chamfer is arranged at the hexagonal position of the deformed steel claw.
The invention has the following advantages:
the invention has long-term popularization value because more valve products have the rotary thin-wall structure, realizes axial positioning and clamping of parts by screwing the screw steel claw by using a wrench, does not cause deformation, reduces the rejection rate of the parts produced before to be more than 45 percent, reduces the rejection rate to be less than 1 percent by using the existing clamp, can quickly clamp and clamp at each time of preparation, and has obvious effect and significance on the aspects of ensuring the production quality, improving the production efficiency, reducing the production cost and the like due to the improvement of the overall efficiency.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example (b):
a clamp for clamping rotary thin-wall parts comprises a deformed steel claw 1 and a steel clamp frame 2, wherein a deformed steel claw thread 11 is arranged at one end of the deformed steel claw 1 and is matched with a steel clamp frame thread 21 arranged in one end of the steel clamp frame 2; the other end of the deformed steel bar claw 1 is of a hexagonal structure and is provided with three 120-degree openings, and the deformed steel bar claw 1 is provided with steps. The inner hole of the steel clamping frame 2 is provided with a chamfer, and the deformed steel claw 1 is matched with the chamfer. The angle of the inner hole of the steel clamping frame 2 is smaller than the chamfer angle of the deformed steel claw 1. And a chamfer is arranged at the hexagonal position of the deformed steel claw 1. Firstly, a three-way part 3 is required to be placed into the deformed steel claw 1, the position of the circular ring 31 is matched with the step surface of the deformed steel claw 1, the part is axially positioned, and the gap between the outer diameter of the circular ring and the inner diameter of the step is kept to be 0.05 mm. The screw-thread steel claw 1 is made of stainless steel 1Cr18Ni9Ti and is provided with three openings of 120 degrees and a width of 15mm at the hexagonal position. Screw thread 11 and the cooperation of 2 screw threads 21 of steel clip frame on the screw-thread steel claw 1, 2 drill way chamfer angles of steel clip frame are less than screw-thread steel claw 1 corresponding position chamfer angles, pack into steel clip frame 2 with tee bend part 3 and screw-thread steel claw 1, use the spanner to screw up screw-thread steel claw 1 back, and screw-thread steel claw 1 hexagonal open position tightens up, and screw-thread steel claw 1 presss from both sides tight part ring 31 department, makes the part can not take place circumferential direction. The integral clamp is connected with a lathe, so that the three-way part 3 can be machined, and the clamping mode is still adopted when other rotary thin-wall parts are machined, and the clamp is redesigned.
