Abstract
The invention relates to a fixture structure for machining a herringbone groove in a plunger part. The fixture structure comprises a fixture body and a flat seat which are fixedly connected with each other, wherein a foot block is concentrically arranged in the fixture body, a positioning screw is arranged in the foot block in a penetrating manner, a spring is sleeved on the periphery of the positioning screw, a female tip is further arranged in the foot block at the end of the positioning screw, flat columns are symmetrically arranged in the flat seat, and knurled screws are symmetrically arranged on two sides of the flat seat, and the end parts of the knurled screws extend into the flat seat and prop against the flat columns. The fixture structure is simple, and the knurled screws are rotated in the flat seat to drive the flat columns to move and clamp the plunger part, so that the center of the plunger part and the rotation center of a machine tool spindle are in a same straight line, and by adopting the female tip, the end part of the plunger part is effectively positioned, the machining stability of the herringbone groove in the plunger part is ensured, problems of cutter relieving and cutter vibration can be avoided, one-time machining for the herringbone groove in the plunger part can be effectively realized, and the machining efficiency is high.
Description
Technical field
The present invention relates to frock clamp, relate in particular to a kind of clamp structure for the processing of plunger member chevron-notch.
Background technology
Plunger matching parts is formed by plunger and plunger bushing precision-fit, and delivery valve matching parts (being made up of delivery valve and delivery valve seat) is equipped with in its top.In order to meet customer requirement, now need in plunger member, process " people " word groove, existing installation way cannot meet the processing of above-mentioned groove, so in the urgent need to designing a kind of novel clamp structure.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied, and a kind of clamp structure for the processing of plunger member chevron-notch is provided, and has effectively realized the disposable processing to plunger member chevron-notch, and working (machining) efficiency is high.
The technical solution adopted in the present invention is as follows:
A kind of clamp structure for the processing of plunger member chevron-notch, comprise affixed each other clamp body and flat position seat, dead head concentric device is in described clamp body, dog screw through-going device is in described dead head, spring housing is contained in the periphery of described dog screw, in the end of described dog screw, in described dead head, returning apparatus the moon is top; The flat position of symmetrical mounting post in described flat position seat, milled screw symmetrical mounting is in the both sides of flat position seat, its end stretch into flat position seat and with described flat post butt.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy for installation, utilize milled screw to rotarily drive the movable and clamping column plug member of flat position post in flat position seat, make the center of plunger member and the pivot of machine tool chief axis on same straight line, by the top effective location of having realized plunger member end of the moon, guaranteed the stability of plunger member in man type chute's processing, avoided cutter relieving, the situation of the cutter that shakes occurs, effectively realized the disposable processing to plunger member chevron-notch, working (machining) efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, clamp body; 2, flat position seat; 3, milled screw; 4, flat position post; 401, lock-screw; 5, plunger member; 6, rolling center; 7, cloudy top; 8, spring; 9, dog screw; 10, dead head.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, a kind of clamp structure for the processing of plunger member chevron-notch, comprise affixed each other clamp body 1 and flat position seat 2, dead head 10 concentric devices are in clamp body 1, dog screw 9 through-going devices are in dead head 10, spring 8 is sleeved on the periphery of dog screw 9, in the end of dog screw 9, in the interior returning apparatus of dead head 10 cloudy top 7; The flat position of flat position seat 2 interior symmetrical mountings post 4, flat position post 4 is by lock-screw 401 locking positionings, milled screw 3 symmetrical mountings are in the both sides of flat position seat 2, its end stretch into flat position seat 2 and with described flat position post 4 butts.
Specific works process of the present invention is as follows:
First clamp body 1 of the present invention is installed on machine chuck, then by one end of plunger member 5 and cloudy top 7 butts, cloudy top 7 stressed and realize elastic lifting by spring 8, then the other end of plunger member 5 and rolling center 6 are connected, guarantee thus the arranged concentric of plunger member 5, then realize the clamping and positioning of flat position post 4 to plunger member 5 by rotation milled screw 3, then open lathe, machine chuck rotarily drives the present invention and plunger member rotation, realizes the chevron-notch processing in plunger member 5 by cutter.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
