A baffle plate is clamped and positioned through the gland, the baffle plate machining clamp is simple to operate and high in positioning precision, and the high-precision mass machining of the soft thin-wall baffle plate can be realized.

Description

Baffle plate clamp for machining
Technical field
The invention belongs to a kind of processing equipment of part, be specifically related to a kind of baffle plate clamp for machining.
Background technology
Baffle plate is as a kind of key components and parts of special equipment, and because requirement on machining accuracy is high, material is softer, yielding, and belongs to thin-wall part again, and clamping difficulty, difficulty of processing is very large.Be difficult to both ensure machining accuracy, the efficiency of processing can be ensured again.Prior art does not also have a kind of suitable tooling fixture to be applicable to process this type of part, therefore urgently designs the special fixture of a kind of lathe, meets the requirement on machining accuracy of part on the one hand, improves the production efficiency of product on the other hand.
Summary of the invention
The present invention proposes for solving prior art Problems existing, its objective is and provides a kind of baffle plate clamp for machining.
Technical scheme of the present invention is: a kind of baffle plate clamp for machining, comprise transition disc, attachment screw is through in the pilot hole of transition disc end face circumference, transition disc is fixed on machine tool chief axis, the other end of transition disc is by fixing through the trip bolt of flange hole and mandrel, pull bar is from outer to inner inserted in the shoulder hole of mandrel axis place formation, and be connected with the piston rod of hydraulic cylinder, jackscrew, retaining jackscrew is screwed in the screwed hole that mandrel is formed radially successively, described jackscrew end is inserted in the helical pitch groove of pull bar, pull bar free end forms rectangular-shaped contiguous block, described contiguous block is by after the gap of gland inwall, circumference is screwed in draw-in groove, described gland outer wall Formation cross-section is the clamping ring of trapezoidal shape.
Described mandrel inwall place forms multiple gas port running through end face and sidewall.
Described mandrel and gland opposing end surface form annular projection.
The present invention realizes the Set and Positioning of baffle plate by gland, simple to operate, setting accuracy is high, the thin wall barrier mass high accuracy processing that matter is soft can be realized, the gas port that mandrel is formed can emptying air in baffle plate clamping to the process of mandrel, eliminate position error, in baffle plate unloading process, blow can easily the baffle plate processed be pulled down by gas port.

Detailed description of the invention
Below, with reference to drawings and Examples, the present invention is described in detail:
As shown in Fig. 1 ~ 10, a kind of baffle plate clamp for machining, comprise transition disc 8, attachment screw 2 is through in the pilot hole 16 of transition disc 8 end face circumference, transition disc 8 is fixed on machine tool chief axis, the other end of transition disc 8 is fixed with mandrel 3 by the trip bolt 7 through flange hole 10, pull bar 1 is from outer to inner inserted in the shoulder hole 17 of mandrel 3 axis place formation, and be connected with the piston rod of hydraulic cylinder, jackscrew 5, retaining jackscrew 6 is screwed in the screwed hole 11 that mandrel 3 is formed radially successively, described jackscrew 5 end is inserted in the helical pitch groove 18 of pull bar 1, pull bar 1 free end forms rectangular-shaped contiguous block 9, described contiguous block 9 is by after the gap 15 of gland 4 inwall, circumference is screwed in draw-in groove 14, described gland 4 outer wall Formation cross-section is the clamping ring 13 of trapezoidal shape.
Described mandrel 3 inwall place forms multiple gas port 12 running through end face and sidewall.
Described mandrel 3 forms annular projection 19 with gland 4 opposing end surface.
Jackscrew 5 is inserted in the helical pitch groove 18 in pull bar 1, pull bar 1 can be made to move vertically, and avoid rotating in a circumferential direction of pull bar 1, retaining jackscrew 6 can stop the radial motion of jackscrew 5, meanwhile, jackscrew 5 also can be avoided long and cause do not allow easy-to-dismount phenomenon.
Using method of the present invention:
The piston rod of hydraulic cylinder is driven to stretch out, pull bar 1 drives gland 4 to move right along axis, the draw-in groove 14 of gland 4 is turned clockwise 90 ° around the contiguous block 9 in pull bar 1, the gap 15 of gland 4 is by after contiguous block 9, gland 4 is separated with pull bar 1, by baffle-plate-sleeve to be processed in the projection 19 of mandrel 3 end face, the air of the baffle plate to be processed by gas port 12 emptying and mandrel 3 end face, again the gap 15 of gland 4 is set with contiguous block 9, the draw-in groove 14 of gland 4 is rotated counterclockwise 90 ° around the contiguous block 9 in pull bar 1, the piston rod of hydraulic cylinder is shunk, baffle plate to be processed is processed.During dismounting workpiece, drive the piston rod of hydraulic cylinder, pull bar 1, gland 4 stretch out, and after separation, pass into gas with air gun from gas port 12, thus are ejected by the baffle plate processed.
The present invention realizes the Set and Positioning of baffle plate by gland, simple to operate, setting accuracy is high, the thin wall barrier mass high accuracy processing that matter is soft can be realized, the gas port that mandrel is formed can emptying air in baffle plate clamping to the process of mandrel, eliminate position error, in baffle plate unloading process, blow can easily the baffle plate processed be pulled down by gas port.
