Abstract

The utility model discloses a rapid clamping and anti-looseness fixture, comprising a base and a handle arranged on the base, a connecting rod and a clamping and anti-looseness head, wherein a clamping axis is covered in the support, the front end of the clamping axis is fixed with a clamping block, a threaded segment is arranged on the clamping axis in the inner side of the clamping block, and a nut is arranged on the threaded segment. The utility model is characterized in that a dish spring or springs with other forms are arranged between the clamping block and the nut. Because of the bounce function of the dish spring, the clamped workpiece does not loose and shift, making the clamped workpiece not loose in the processing course. The utility model can be widely used for fast clamping of workpieces when the machine tool and the processing center processes workpieces, and can be also used for positioning and mounting relevant moulds in factories.

Description

Clamp anti-release clamp fast

Technical field:

The utility model relates to a kind of mechanical clamp, is specifically related to a kind of mechanical clamp of getting loose of preventing, is applicable to workplaces such as lathe and machining center, to the quick loading and unloading of processing work.

Background technology:

Anchor clamps are one of indispensable instruments of mechanical processing industry making mechanical part, anchor clamps are extensive use of a kind of fast fixture in factory's frock at present, but directly connect between the nut owing to clamp in this device and axle, putting when parts to be processed are fixedly clamped, because the effect of the linkage of clamp, the normal workpiece meeting loose shift that clamps that makes causes machine tooling substandard products or waste product.

The utility model content:

The utility model causes not having the problem of due clamping action in order to solve the workpiece loose shift of above-mentioned anchor clamps, and a kind of back loose shift novel clamp that prevents to clamp is provided.

The utility model comprises a kind of anti-release clamp, include base, be installed in the locking head of handle, connecting rod and clamping on the base, be set with clamp shaft in the bearing, the clamp shaft front end is fixed with clamp, on the clamp shaft of clamp inboard thread segment is arranged, nut is arranged on the thread segment, it is characterized in that between clamp and nut, being equipped with disk spring or other forms of spring.

Described other forms of spring is an elastomeric pad.

On the thread segment of termination, the clamp outside nut and corresponding alignment pin etc. can also be installed.

The clamp of the utility model clamp shaft termination can have the various fixed mode, the one, clamp is set in the leading portion of clamp shaft, the clamp outside has nut to be welded on the clamp shaft, plays the position-limiting action to clamp, on the clamp shaft of clamp inboard external screw thread is arranged, external screw thread is with nut outward, between nut and the clamp disk spring is installed, the rotation nut is to fix to clamp piece, because the elastic force of disk spring, make that nut can loose shift, thereby play the effect of clamping.The 2nd, will fix with pin between clamp and the clamp shaft, it is identical that remaining is connected and fixed mode.In addition, can also carry out specialized designs according to different workpieces and processing machine.

The shape of the workpiece that the shape of clamp clamps according to need and deciding can be circular, square, triangle or other required geometries.

The beneficial effects of the utility model are: because the elastic force effect of disk spring, caught workpiece can loose shift, makes can not get loose in the caught workpiece reprocessing process.The utility model can be widely used in the usefulness of lathe and machining center quick clamping work pieces when processing work, also can be used for the usefulness of factory to location and installation such as related die.

Description of drawings:

Fig. 1 is the utility model structural representation;

Among the figure, 1, base, 2, bearing, 3, handle, 4, clamp locking head, 5, clamp shaft, 6, connecting rod, 7, nut, 8, pad, 9, disk spring, 10, clamp.

The specific embodiment:

With reference to accompanying drawing.

Clamp anti-release clamp fast, include base 1 and be installed in handle 3, the connecting rod 6 on the base 1 and clamp locking 4, clamping locking 4 is nuts of installing on the thread segment of termination, clamp 10 outside, be set with clamp shaft 5 in the bearing 2, clamp shaft 5 front ends are fixed with clamp 10, on the clamp shaft 5 of clamp 10 inboards thread segment is arranged, nut 7 is arranged on the thread segment, disk spring 9 and pad 8 are installed between clamp 10 and the nut 7.

During use because the elastic force effect of disk spring, make clamp head can loose shift, add clamp outboard nut and inboard nut the effect of power in opposite directions, make that the folder power of anchor clamps is big, can not get loose, fixing more reliable during clamping.

Claims

1, clamps anti-release clamp fast, include base and be installed in handle, the connecting rod on the base and clamp locking head, be set with clamp shaft in the bearing, the clamp shaft front end is fixed with clamp, on the clamp shaft of clamp inboard thread segment is arranged, nut is arranged on the thread segment, it is characterized in that between clamp and nut, being equipped with disk spring or other forms of spring.

2, anti-release clamp according to claim 1 is characterized in that described other forms of spring is an elastomeric pad.
