Abstract
The invention discloses a fixing device for sealing cover polishing. The fixing device comprises a frame; the fixing device further comprises a cam, a handle, an upright, a tapered ejector block, clamping jaws, a spring and spring pieces, all of which are arranged on the frame from top to bottom; a lower end of the upright is fixed at the center of the frame; the spring sleeves the middle of the upright; the tapered ejector block sleeves the upright and is located over the spring; the cam is pivoted to an upper portion of the upright, and a lower end of the cam props against a top surface of the tapered ejector block; the tapered ejector block is in a taper shape big in top and small in bottom and a sidewall of the tapered ejector block is a tapered surface; at least three clamping jaws are arranged and distributed circumferentially and uniformly on an upper portion of the frame; lower ends of the clamping jaws are hinged to the upper portion of the frame, and inner sides of upper ends of the clamping jaws prop against the tapered surface of the tapered ejector block; the handle is in threaded connection with an outer edge of the cam; and lower ends of the spring pieces are fixed on the frame through fastening screws, while upper ends of the spring pieces prop against the middles of the clamping jaws; the fixing device for sealing cover polishing is capable of realizing clamping and positioning to a workpiece and also capable of quickly clamping the workpiece, and therefore, the efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of fixture, be specifically related to a kind of seal cover polishing fixture.
Background technology
Half gland retainer plate is the important security personnel's part of on automobile axle, in the running of automobile, subjects the weight of whole vehicle body and vehicle-mounted cargo.Meanwhile, due to the change of road conditions, it also will bear the alternate stress of various complexity.Therefore, the quality of half gland retainer plate quality, directly has influence on the driving safety of vehicle.
In prior art, half gland retainer plate is generally forging and makes, and its surface can produce many burrs, need to carry out polishing.Be generally that workman is fixed processing by hand-held, crudy is difficult to ensure, nor safety, efficiency is also low.
Summary of the invention
The invention is intended to provide a kind of seal cover polishing fixture, to improve working (machining) efficiency.
In base case: seal cover polishing fixture, comprises frame, also comprises cam, handle, column, cone-shaped ejecting block, jaw, spring and spring leaf that frame is arranged from top to bottom, column lower end is fixed on frame central place, spring housing is connected in the middle part of column, cone-shaped ejecting block to be socketed on column and to be positioned at above spring, cam is articulated in column top, lower cam end and cone-shaped ejecting block end face offset, the taper that cone-shaped ejecting block is big up and small down and its sidewall is taper surface, jaw is at least three, and circumference is distributed on upper rack, jaw lower end is hinged on upper rack, offset with the taper surface of cone-shaped ejecting block inside jaw upper end, handle threads is connected in cam outer rim, spring leaf lower end is fixed in frame by holding screw, offset in the middle part of spring leaf upper end and jaw.
Principle of the present invention: during use, be placed on by workpiece in frame, then joystick driving handle rotates forward cam, and cam moves down against cone-shaped ejecting block against the force of the spring, jaw overcomes spring leaf resistance and outwards swings under the effect of cone-shaped ejecting block, thus by Workpiece clamping; After machining, joystick driving handle rotates backward cam, under the effect of spring and spring leaf, and cone-shaped ejecting block and pawl return, thus unclamp workpiece.
The present invention can realize the clamping and positioning to workpiece, to workpiece quick-clamping, can substantially increase efficiency.
Preferred version one, based on the further optimization of scheme, column lower end is thread segment and is threaded in frame central place; Fast and easy installing/dismounting.
Preferred version two, the preferably further optimization of one, upper rack has for the hinged opening in jaw lower end, and cam is provided with stop surfaces; Convenient stablizing uses and fixes.
Preferred version three, the preferably further optimization of two, jaw is three; Clamp more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: frame 10, spring leaf 11, jaw 20, cone-shaped ejecting block 21, cam 22, handle 23, column 30, spring 31.
Embodiment is substantially as shown in Figure 1: seal cover polishing fixture, comprises frame, also comprises cam, handle, column, cone-shaped ejecting block, jaw, spring and spring leaf that frame is arranged from top to bottom, column lower end is thread segment and is threaded in frame central place, spring housing is connected in the middle part of column, cone-shaped ejecting block to be socketed on column and to be positioned at above spring, cam is articulated in column top, lower cam end and cone-shaped ejecting block end face offset, the taper that cone-shaped ejecting block is big up and small down and its sidewall is taper surface, jaw is three, and circumference is distributed on upper rack, jaw lower end is hinged on upper rack, offset with the taper surface of cone-shaped ejecting block inside jaw upper end, handle threads is connected in cam outer rim, spring leaf lower end is fixed in frame by holding screw, offset in the middle part of spring leaf upper end and jaw, upper rack has for the hinged opening in jaw lower end, cam is provided with stop surfaces.
During use, be placed on by workpiece in frame, then joystick driving handle rotates forward cam, and cam moves down against cone-shaped ejecting block against the force of the spring, and jaw overcomes spring leaf resistance and outwards swings under the effect of cone-shaped ejecting block, thus by Workpiece clamping; After machining, joystick driving handle rotates backward cam, under the effect of spring and spring leaf, and cone-shaped ejecting block and pawl return, thus unclamp workpiece.
