Description
Technical Field
The utility model relates to the technical field of machining clamps, in particular to a quick clamp for a polishing platform, which is used for improving the clamping efficiency and the operation safety of small-sized workpieces.
Background
In the polishing process of metal workpieces, the traditional bench clamp generally adopts an adjustable fixed jaw and a screw to drive a movable jaw to realize clamping operation of the workpieces, the clamping force is stable, the handle is required to be rotated for clamping for many times, the operation is time-consuming, and especially for small parts which need frequent replacement, the efficiency is low. In addition, the operator holds the high-speed rotary tool in the polishing operation and easily causes false touch, so that potential safety hazards exist. Therefore, a special fixture with the capabilities of rapid clamping, safety protection and size adaptation is needed.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model aims to provide a quick clamp for a polishing platform so as to solve the defects of the prior art.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
A quick clamp for a polishing platform. The clamp comprises a clamp body (1), two sliding rails (11) which are arranged in parallel are arranged at the top of the clamp body, sliding grooves which are matched with the sliding rails (11) are arranged at the bottom of an adjustable fixed jaw (2), locking screws (21) are arranged at two sides of the adjustable fixed jaw, the adjustable fixed jaw is rigidly connected with nuts (41) of a screw-nut pair (4), sliding grooves which are matched with the sliding rails (11) are arranged at the bottom of a quick moving jaw (3) and are connected with push rods (51) of a quick clamping device (5), two ends of a screw rod (42) of the screw-nut pair (4) are fixed on one side of the clamp body (1) through bearing blocks (12), a rotary handle (43) is arranged at one outward end of the screw rod, a base (52) of the quick clamping device (5) is fixed on the other side of the clamp body (1), the push rods (51) are driven to move linearly along the sliding rails (11) through pulling the quick clamping handles (53), and magnetic replaceable soft clamping pads (54) are arranged on working surfaces of the adjustable fixed jaw (2) and the quick moving jaw (3).
Preferably, the sliding rail (11) is an L-shaped linear guide rail.
Preferably, the screw (42) is a trapezoidal threaded screw, and the axis of the screw is parallel to the extending direction of the sliding rail (11).
Preferably, the quick clamping device (5) is a crank guide rod type quick locking device, and the quick clamping handle (53) is a clamping handle capable of swinging in a reciprocating mode.

FIG. 1 is a schematic perspective view of the present utility model;
FIG. 2 is a schematic diagram of the connection of the components of the present utility model;
Fig. 3 is a schematic diagram of the operation of the quick clamp device.
Detailed Description
As shown in fig. 1-3, the clamp body (1) is cast integrally by cast iron, and two L-shaped slide rails (11) are machined at the top. The adjustable fixed jaw (2) is matched with the sliding rail (11) through a bottom sliding groove, locking screws (21) arranged on two sides can lock the adjustable fixed jaw and the sliding rail (11) relatively, and the back surface of the adjustable fixed jaw (2) is fixedly connected with a nut (41) of the screw-nut pair (4) through a set screw. The screw rod (42) is trapezoidal threads, two ends of the screw rod are supported by the bearing blocks (12) of the clamp body (1), and the rotating handle (43) can drive the adjustable fixed jaw (2) to move along the sliding rail (11) so as to realize rough adjustment of the clamping range. And the locking screws (21) arranged on two sides of the adjustable fixed jaw (2) are screwed down, so that the stability of the adjustable fixed jaw (2) is improved.
The quick clamping device (5) adopts a crank guide rod type structure, the base (52) is fixed on the right side of the clamp body (1) through a screw, and the front end of the push rod (51) is fixedly connected with the quick moving jaw (3) through a bolt. When the handle (53) is pulled, the crank drives the connecting rod to press the push rod (51) to generate linear displacement, and the quick moving jaw (3) is driven to quickly approach or separate from a workpiece and is self-locked at a dead point position. The jaw working surface is provided with a soft clamping pad (54) which can be replaced by magnetic attraction, so that the workpiece is prevented from slipping, and the workpiece can be replaced conveniently.
During operation, the screw rod handle (43) is rotated to adjust the adjustable fixed jaw (2) to a proper position, then the locking screws (21) at two sides are screwed, after a workpiece is placed in the screw rod, the quick clamping handle (53) is pulled forward by one hand to finish clamping, when the screw rod handle is loosened, the handle (53) is pushed backward, the quick moving jaw (3) is reset automatically, and no tool assistance is needed in the whole process.
The clamping device has the beneficial effects that the clamping size of the jaw and the step operation of quick clamping and locking are adjusted through the screw rod, so that the requirements of large-scale size adaptation and instantaneous clamping are met.
The single-handle operation mode of the quick clamping device obviously shortens the clamping time, and is particularly suitable for pipeline polishing operation.
Jaw self-locking function avoids the pine that vibration caused to take off, and removable soft grip pad can replace rapidly when necessary is inhaled to magnetism, and soft grip pad reduces work piece surface damage risk.
