Abstract
The utility model belongs to a frock clamp for tensioning an inner hole. The frock clamp for tensioning the inner hole is characterized by comprising a spring reset and locating device, a double-taper press rod and a wedge press device. The frock clamp for tensioning the inner hole is mainly formed by an inner hexagonal spanner, the double-taper press rod, a locating seat, a spring seat, a spring, a wedge ejector column and a hexagon nut. The double-taper press rod and the spring are connected with the locating seat through threads. The spring seat is in clearance fit with the wedge ejector column, and the spring is in clearance fit with the wedge ejector column. The frock clamp for tensioning the inner hole is suitable for turning (milling) pin machining of axial plunger pump case parts, and the frock clamp is simple in manufacturing, easy to operate, low in cost and high in locating accuracy. Operation of workers is simple and fast, and production efficiency is high.
Description
Technical field
The utility model belongs to the frock clamp of a kind of tensioning endoporus in the mechanical processing industry, is highly suitable for Hydraulic Elements technology field.
Background technology
At present, plunger pump shell is cut in the process at car (milling), and Workpiece clamping generally adopts the profile clamping mode.There is following defective in this mode: frock clamp is made complicated, during workman's operating cost and inconvenience.
Summary of the invention
The purpose of this utility model: use tensioning endoporus mode fixation workpiece instead, simplify frock clamp manufacturing process, it is more simple and efficient that the workman is operated.
The technical solution of the utility model is achieved in that a kind of frock clamp of tensioning endoporus, it is characterized in that it comprises spring reset and positioner, double tapered depression bar and wedge hold down gag; It mainly is comprised of Allen wrench, double tapered depression bar, positioning seat, spring base, spring, wedge fore-set, hex nut; Double tapered depression bar, spring base and positioning seat thread connection, spring base and wedge fore-set are matched in clearance, spring and wedge fore-set are matched in clearance.
The utility model has the advantages that: when processing housing part (especially short seam), can't or inconvenience when using the profile clamping, adopt should in a method clamping work pieces, convenient and swift, frock clamp is manufactured simple, cost is low.
Description of drawings
Fig. 1 is the utility model---casing of hydraulic pump car (milling) is cut the tooling device structural representation;
Illustration: 1, Allen wrench 2, double tapered depression bar 3, positioning seat 4, spring base 5, spring 6, wedge fore-set 7, hex nut.
The specific embodiment
As shown in Figure 1: a kind of frock clamp of tensioning endoporus, it comprises spring reset and positioner, double tapered depression bar 2 and wedge hold down gag; It mainly is comprised of Allen wrench 1, double tapered depression bar 2, positioning seat 3, spring base 4, spring 5, wedge fore-set 6, hex nut 7; Double tapered depression bar 2, spring base 4 are used thread connection with positioning seat 3, and spring base 4 is matched in clearance with wedge fore-set 6, and spring 5 is matched in clearance with wedge fore-set 6.
This frock clamp mainly is comprised of localization part and tensioning apparatus, during use, first holder 3 band nuts one end is fixedly clamped on lathe with scroll chuck, do not lay workpiece before, make spring 5 be in the nature state that stretches.After workpiece is loaded onto positioning seat 3, rotate in the direction of the clock double tapered depression bar 2 by inner hexagon spanner 1, force wedge fore-set 6 to radially mobile until press the pump case inner surface.In the time will taking out workpiece, counterclockwise rotate depression bar 2 with spanner, wedge fore-set 6 gets loose, and resets under spring action, gets back to original state.This moment is just desirable to go out workpiece.
