Abstract

The utility model discloses a clamping device with an adjustable clamping range, which comprises a soft jaw seat, a T-shaped nut, a screw, a cushion plate and a soft jaw. The screw matches with the T-shaped nut, a tooth structure which is arranged along the radial direction of a chuck and matches with teeth on the chuck is disposed on the back surface of the soft jaw seat, a T-shaped groove arranged along the radial direction of the chuck is disposed on the front surface of the soft jaw seat, the T-shaped nut is mounted in the T-shaped groove and can slide in the T-shaped groove, a hole is arranged on the cushion plate and matches with a part, which is protruded from the T-shaped groove, of the T-shaped nut, the cushion plate is sleeved on the part, which is protruded from the T-shaped groove, of the T-shaped nut, the screw matches with the T-shaped nut so that the soft jaw is fixed onto the soft jaw seat, and the soft jaw is tightly pressed on the cushion plate. The soft jaw and the soft jaw seat are separable, only the soft jaw needs to be replaced when damaged, and cost can be reduced. In addition, relative positions of the soft jaw and the soft jaw seat can be adjusted, and accordingly the clamping device with the adjustable clamping range is applicable to processing parts of the same type but with different diameters.

Description

A kind of clamping device of scalable clamping scope

Technical field

The utility model relates to Digit Control Machine Tool, relates in particular to a kind of clamping device of scalable clamping scope.

Background technology

The outer ring of bearing class part, the profile of its part of inner ring are roughly the same; Just its internal diameter or outside dimension are not of uniform size, add man-hour in the past, and the inside and outside circle of the bearing of different-diameter adds need be equipped with the soft pawl of corresponding special use man-hour; Adjustment is very loaded down with trivial details, very uneconomical when changing processing parts.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of clamping device of scalable clamping scope, the frequency of when reducing Machining of Shaft-type Parts soft pawl being regulated.

Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:

A kind of clamping device of scalable clamping scope; Comprise soft pawl seat, T type nut, with suitable screw, backing plate and the soft pawl of T type nut, be provided with at the back side of soft pawl seat along chuck radially and with the suitable toothing of the tooth on the chuck, be provided with along chuck T type groove radially in the front of soft pawl seat; T type nut is installed in the T type groove; And can in T type groove, slide, on backing plate, being provided with and the suitable hole of T type nut protrusion T type slot part, backing plate is sleeved on T type nut protrusion T type slot part; Soft pawl passes through the matching and fixing of screw and T type nut on soft pawl seat, and compresses backing plate.

During installation, locate it on the relevant position of chuck, and soft pawl seat is fixed on the chuck through fixture through the toothing at the soft pawl seat back side; Through T type nut and screw backing plate, soft pawl are fixed on the soft pawl seat again.This clamping device is one group in use to be used simultaneously, is the center with the chuck cross section center of circle, evenly is fixed on the chuck, is preferably triplets and uses simultaneously.

During use, unclamp the screw that is connected with T type nut, install and to treat that the diameter dimension of clamping part adjusts the relevant position of soft pawl and soft swivel base,, pass through screw and T type nut fixedly backing plate and soft pawl again to realize the adjustment of clamping range.When the soft pawl clamping range of adjustment, only need with the soft pawl of vernier caliper measurement and soft pawl seat relative size radially, general size is consistent gets final product in assurance; The backing plate purpose is to realize the axial location of processing parts.

Said T type groove is two, and the position is built up in the radial direction both sides of chuck cross section symmetrically.

Beneficial effect: the clamping device of the scalable clamping scope that the utility model provides, soft pawl and soft pawl seat are separate types, when soft pawl damages, only need change soft pawl, can reduce cost; Soft pawl and soft pawl seat relative position can be adjusted, and can adapt to the processing of same kind, different-diameter part; Backing plate can be changed according to the design of part locating surface; When many kinds, small batch part processing, this device can be adjusted the clamping diameter range easily and efficiently, reduces the non-cutting time of adjustment anchor clamps annex, increases work efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 be among Fig. 1 A-A to enlarged diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

As accompanying drawing 1, shown in Figure 2 be a kind of clamping device of scalable clamping scope; Comprise soft pawl seat 1, T type nut 3, with suitable screw 5, backing plate 4 and the soft pawl 6 of T type nut 3; Be provided with at the back side of soft pawl seat 1 along chuck radially and with the suitable toothing of the tooth on the chuck, be provided with along chuck T type groove 2 radially in the front of soft pawl seat 1, T type nut 3 is installed in the T type groove 2; On backing plate 4, be provided with and the suitable hole of T type nut 3 protrusion T type groove 2 parts; Backing plate 4 is sleeved on T type nut 3 protrusion T type grooves 2 parts, and the matching and fixing of soft pawl 6 through screw 5 and T type nut and compresses backing plate 4 on soft pawl seat 1.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
