Abstract

The utility model relates to a wedge block type automatic centring clamp, which is composed of a clamping head piece 1 and a taper sleeve 2, wherein, the taper sleeve 2 is circular, the outer surface of the taper sleeve 2 is provided with a circular bead, the middle part in the taper sleeve 2 is provided with a bulge, and the front part is in the shape of a cone; the root of the clamping head piece 1 is in clearance fit with the taper sleeve 2, and the clamping head piece 1 can slide, and clamping claws are evenly distributed on the front part. Since the utility model adopts that the clamping head piece is connected with a piston through a connecting sleeve, and the incline of the taper sleeve enables the clamping claws to clamp workpieces. The clamp has the advantages of an automatic centring function, simple structure, flexible installation and clamping, balanced work and good labour conditions, can not only be connected with a hydraulic cylinder, but also can be connected and used with a pneumatic cylinder. The clamp can be popularized to industry such as machine building, automobile and tractor making, tool making, etc., can be used for carrying out processes of shaft type parts, tubular goods parts, flanges and shafts, cutters, roughcasts, geological drilling rods, etc., and especially can be used in approved products which need to be clamped and positioned when go into mass production.

Description

The Wedge-type automatically centering fixture

The utility model relates to the instrument that uses in a kind of machine-building, particularly a kind of Wedge-type automatically centering fixture.

Normally used mounting and clamping system is in the process of clamping workpiece, because the defective of anchor clamps, workpiece is difficult for the centering center, cause friction welding after, weld seam does not just reach the requirement of technology.

The purpose of this utility model is to provide a kind of Wedge-type automatically centering fixture device, and it makes workpiece easy centering center behind clamping, and weld seam standard after the friction welding satisfies the requirement of technology.

The purpose of this utility model is achieved in that it is made up of chuck spare (1), tapered sleeve (2), and tapered sleeve (2) has the circle of shoulder for outer surface, there is projection at middle part in it, the front portion is conical, and the root of chuck spare (1) is connected with equipment by internal thread, and the front portion is evenly distributed with claw.

During work, this anchor clamps integral body is connected the machine tool chief axis end with screw, chuck spare 1 is connected with piston by adapter sleeve, and chuck (1) root and tapered sleeve (2) matched in clearance and slidably are when piston is moved to the left, driving chuck spare is moved to the left, the inclined-plane of tapered sleeve 2 makes claw clamping work pieces 3, otherwise, when piston moves right, the drive collet body moves right, and workpiece is unclamped.

The utility model is owing to adopted chuck spare to be connected with piston by adapter sleeve, and the inclined-plane of tapered sleeve makes the claw clamping work pieces, and anchor clamps have the automatic capturing center function, and are simple in structure, and clamping is flexible, the work balance, and working condition is good.Both can be connected, also can be connected use with pneumatic cylinder with hydraulic cylinder.These anchor clamps can be generalized to the machine manufacturing, automobile and tractor is made, and industries such as instrument manufacturing are used to carry out axial workpiece, the processing of pipe part, ring flange and axle and cutter blank and geologic drilling rod etc. is particularly produced in batches in the approved product that needs clamping and positioning.

Accompanying drawing is a structural representation of the present utility model.

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

As shown in the figure, the utility model is made up of chuck spare 1, tapered sleeve 2, and tapered sleeve 2 has the circle of shoulder for outer surface, and projection, front portion are arranged is taper shape at the middle part in it, the root of chuck spare 1 and tapered sleeve 2 matched in clearance, and can slide, the front portion is evenly distributed with claw.Must guarantee machining accuracy, want the concrete cleaning of retaining clip in the use, forbid to grind.Need select for use the 60Si2Mn material to make, common material influences service life.

Claims (2)

1, a kind of Wedge-type automatically centering fixture, it is made up of chuck spare (1), tapered sleeve (2), it is characterized in that: tapered sleeve (2) has the circle of shoulder for outer surface, there is projection at middle part in it, anterior is conical, the root of chuck spare (1) and tapered sleeve (2) matched in clearance, the front portion is evenly distributed with claw.
