Abstract
A clamp used for holding hole-pattern workpieces for thermal treatment belongs to the technical field of machine tool accessories, and aims to provide a clamp with simple structure, flexible and convenient use, firmness, safety, low probability of rusting, and low price. The clamp adopts the technical scheme that a clamping seat, claws, a link plate, a screw, a lead screw and a gland bush are included; one end of the cylindrical clamping seat is connected with the main shaft of a machine tool, and the other end thereof is sealed by the gland bush; the lead screw is positioned in the cylindrical axis of the clamping seat; the screw is assembled on the lead screw; the three claws pass through the wall of the clamping seat and are uniformly mounted along the circumference of the clamping seat; and the inner end surfaces of the claws are connected with the outer circumference of the screw through the link plate. In the clamp, the workpieces are directly held rather than being held through relying on a chuck, a finial, and a clamping tip, thereby simplifying the routines of work, eliminating the disadvantages such as difficult workpiece loading and unloading caused by rust clamp, and avoiding the potential falling off hazard because the holding length of the common chuck jaw is small or the finial and the workpiece are not in well fit. The clamp is suitable for replacing the holding clamp for hole-pattern workpieces in original thermal treatment production.
Description
Technical field
The utility model relate to a kind of in the surface heat process for producing jig of clamping pass workpiece, belong to the machine tool accessories technical field.
Background technology
In the surface heat process for producing, workpiece needs heating and cooling all the time, and chuck commonly used, top, tailstock cause the work-handling difficulty because of the very fast generation corrosion of frequent water cooling, even stuck.For this reason, need to solve the existing defective of jig in the existing surface heat process for producing.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple structure, flexible and convenient to use, stable safely, be difficult for corrosion, the cheap jig that is used for heat treatment pass piece-holder.
The technical scheme that solves the problems of the technologies described above is:
A kind of jig that is used for heat treatment pass piece-holder, it is made up of deck, claw, yoke plate, screw, leading screw, gland, deck is a cylinder, and an end is connected with machine tool chief axis, and the other end is sealed by gland, leading screw is located on the cylinder axis of deck, screw is fitted on the leading screw, and claw is 3, passes the deck wall and evenly installs along the deck circumference, the claw outer face is higher than the deck external peripheral surface, and the claw inner face is connected with the screw excircle by yoke plate.
The above-mentioned jig that is used for heat treatment pass piece-holder, described leading screw one end is that axle sleeve is connected with deck, the other end passes gland, by bearings, is rotary with locking nut on the leading screw in the gland outside in the gland inboard.
The end that the above-mentioned jig that is used for heat treatment pass piece-holder, described deck are connected with machine tool chief axis is a taper shank, and taper shank and tapered bore of machine tool spindle are complementary.
The above-mentioned jig that is used for heat treatment pass piece-holder, described 3 claws have 1: 200 gradient, divide equally installation along the deck circumference with hexagonal angle.
The above-mentioned jig that is used for heat treatment pass piece-holder, described claw has inverted cone surface and anti-slip tank, and screw, leading screw are T type screw thread.
The above-mentioned jig that is used for heat treatment pass piece-holder, described claw, leading screw, yoke plate are stainless steel, screw is an aluminium bronze.
The utility model is designed the antirust jig in a kind of hole at existing heat treatment jig drawback, relying on chuck, top Ka Ding to become directly former workpiece holds, simplified working procedure, eliminate the drawbacks such as work-handling difficulty that the frequent corrosion of jig causes, and stopped the hidden danger that common chuck jaw holds the length weak point or causes workpiece to come off with top mismate.The utlity model has and make simply, with low cost, easy to use, flexibly reliable, be difficult for advantages such as corrosion, be suitable for substituting the jig that holds that mesopore class workpiece is produced in original heat treatment, also can be widely used in other pass workpiece processing.
