Abstract

The invention specifically provides a clamp for a thin-walled part with a lightening hole. The problem that an existing thin-walled part with the lightening hole easily deforms, influences the production efficiency and enables waste to be severe during machining is solved. The clamp comprises a rectangular connecting base plate connected with each hydraulic chuck main claw, wherein the middle of the connecting base plate is provided with an adjusting hole, the end face of one end of the connecting base plate is provided with a stepped hole communicated with and perpendicular to the adjusting hole, a column-shaped chuck rod penetrates the adjusting hole, the side wall of one end of the chuck rod is provided with a key groove opposite to the position of the stepped hole, the side wall of the other end of the chuck rod is provided with a clamping alveolar socket, a positioning screw in threaded connection with the stepped hole and in contact with the bottom end of the key groove is screwed in the stepped hole, a positioning block is arranged under the clamping alveolar socket and provided with a stepped hole I, and a fastening screw connected with the connecting base plate is screwed in the stepped hole I. The clamp enables the part deformation possibility to be reduced by higher than 90%, and the production, research and development input cost is reduced.

Description

Band lightening hole thin-walled parts fixture
Technical field
The present invention relates to auto parts and components machined servicing unit, be specially a kind of band lightening hole thin-walled parts fixture.
Background technology
It is little that auto parts and components machining industry faces profit margin, and client is more and more higher to the requirement of product, is the new direction that machined enterprise is constantly explored with lightening hole thin-walled parts.
The existing processing with lightening hole thin-walled parts adopts hydraulic clamp that its outside is clamped more, processes, and in process, the distortion probability of part is larger, and utilization rate is low, when affecting production efficiency, causes the waste of cost.
Summary of the invention
The present invention existingly to add and yieldingly affects production efficiency and waste serious problem with lightening hole thin-walled parts in order to solve man-hour, and a kind of band lightening hole thin-walled parts fixture is provided.
The present invention adopts following technical scheme to realize: band lightening hole thin-walled parts fixture, comprise that the rectangle being connected with the female pawl of each oild chuck connects base plate, the centre that connects base plate has adjustment hole, and connection base plate one side end face has and communicates with adjustment hole and vertical shoulder hole, in adjustment hole, be installed with column chuck bar, chuck bar one end sidewalls has the keyway relative with shoulder hole position, chuck bar the other end sidewall has clamping alveolus, in shoulder hole, be screwed with the dog screw that is threaded with it and contacts with keyway bottom, clamp alveolus below and be provided with locating piece, on locating piece, have shoulder hole I, in shoulder hole I, be screwed with and the trip bolt that connects base plate and be connected.
When operation, this fixture is arranged on three female pawls of hydraulic clamp, drive female pawl to drive the clamping alveolus on chuck bar that the lightening hole inwall of thin-walled parts is clamped by hydraulic mechanism, regulate chuck by dog screw simultaneously, the bite that ensures three chucks prevents from pressing from both sides askew at grade, locating piece is used for locating the end face of thin-walled parts, use the less pressure can be by Workpiece clamping, and carry out end face location, overcome and existingly added and yieldingly affect production efficiency and waste serious problem man-hour with lightening hole thin-walled parts.
Reasonable in design of the present invention is reliable, draws through test of many times, and the probability of part deformation reduces more than 90%, ensures that dimensional accuracy is in design drawing claimed range; And need not order special hydraulically operated fixture and equipment just can meet machined demand, and not increasing under the prerequisite of equipment investment, expand production and processing scope, reduce R&D and production input cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1-connects base plate, 2-shoulder hole, 3-chuck bar, 4-keyway, 5-clamps alveolus, 6-dog screw, 7-locating piece, 8-shoulder hole I, 9-trip bolt.
Detailed description of the invention
Band lightening hole thin-walled parts fixture, comprise that the rectangle being connected with the female pawl of each oild chuck connects base plate 1, the centre that connects base plate 1 has adjustment hole, and connection base plate 1 one side end faces have and communicate with adjustment hole and vertical shoulder hole 2, in adjustment hole, be installed with column chuck bar 3, chuck bar 3 one end sidewalls have the keyway relative with shoulder hole position 4, chuck bar 3 the other end sidewalls have and clamp alveolus 5, in shoulder hole 2, be screwed with the dog screw 6 that is threaded with it and contacts with keyway 4 bottoms, clamp alveolus 5 belows and be provided with locating piece 7, on locating piece 7, have shoulder hole I8, in shoulder hole I8, be screwed with and the trip bolt 9 that connects base plate 1 and be connected.
