Abstract
The invention discloses a fixing device for grinding of a rear axle shaft sealing cover. A round blind hole is formed in a machine frame in the vertical direction, and a square blind hole is formed in the machine frame in the horizontal direction. A cylindrical pull rod slides in the round blind hole, and a cuboid sliding block slides in the square blind hole. A first through hole is formed in the middle of the pull rod, a first wedged face is arranged on the lower inner wall of the first through hole, and a second wedged face is correspondingly arranged in the middle of the sliding block. A screw rod is integrally arranged at the outer end of the sliding block, one end of a threaded cover is connected with the screw rod through threads, and the end face of the end of the threaded cover abuts against the side wall of the machine frame; the other end of the threaded cover is fixed to a handle, a positioning block is embedded into the upper end of the round blind hole, and a second through hole for the pull rod to slide is formed in the center of the positioning block; a pressing plate is connected to the upper end of the pull rod in a sleeving mode, and the pressing plate and the pull rod are locked through a nut. A spring is fixed between the bottom of the square blind hole and the bottom of the pull rod. By means of the fixing device, a workpiece can be clamped and positioned and can be quickly clamped, so that efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of fixture, be specifically related to a kind of rear sedan-chair half gland retainer plate 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, needs to polish.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 rear sedan-chair half gland retainer plate polishing fixture, to improve working (machining) efficiency.
In base case: rear sedan-chair half gland retainer plate polishing fixture, comprises frame, also comprises pull bar, pressing plate, locating piece, sliding shoe, threaded cap, handle and spring that frame is arranged from top to bottom, frame vertical direction has blind round hole, rack level direction has square blind hole, pull bar is cylindric and slides in blind round hole, sliding shoe is rectangular-shaped and slides in square blind hole, have the first through hole in the middle part of pull bar and on the downside of the first through hole, inwall have the first wedge surface, in the middle part of sliding shoe, correspondence is provided with the second wedge surface, sliding shoe outer end has been wholely set screw rod, threaded cap one end is connected with screw flight and end face and frame side wall offset, the threaded cap other end and handle are fixed, locating piece is bumped into blind round hole upper end, locating piece center has the second through hole slided for pull bar, pressing plate is socketed in pull bar upper end and also and between pull bar passes through nut check, between spring is fixed on bottom square blind via bottom and pull bar.
Advantage of the present invention and principle: 1, handle be arranged so that the rotation of threaded cap is convenient; 2, the coordinating of the first wedge surface and the second wedge surface, pull bar can be made vertically to slide steadily; 3, form lead screw pair between threaded cap and sliding shoe, rotate the quick movement that threaded cap can realize sliding shoe.During use, workpiece is placed on locating piece, then forward drive handle, thus drive threaded cap to rotate forward, and then drive sliding shoe outwards movement, and then pass through the cooperation of the second wedge surface, the first wedge surface, drive pull bar against the force of the spring to move down, thus band dynamic pressure plate is by Work-sheet pressing.After machining, reverse drive handle, thus drive threaded cap to rotate backward, and then drive sliding shoe to move inward, pull bar moves up under the action of the spring, thus unclamps 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, pull bar upper end is provided with axle journal, and pressing plate is socketed on axle journal; Facilitate pressing plate fixing on pull bar.
Preferred version two, the preferably further optimization of one, locating piece central protuberance has positioning boss, and positioning boss is circumferentially with chamfering; Fast and easy realizes location to workpiece, facilitates workpiece to take off from locating piece simultaneously.
Preferred version three, the preferably further optimization of two, the threaded cap other end is connected by pin with handle; Fast and easy is stable fixing.
Accompanying drawing explanation
Fig. 1 is the schematic front view 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 11, sliding shoe 20, locating piece 21, pull bar 30, pressing plate 31, workpiece 40, threaded cap 50, handle 51.
Embodiment is substantially as shown in Figure 1: rear sedan-chair half gland retainer plate polishing fixture, comprises frame 10, also comprise pull bar 30, pressing plate 31, locating piece 21, sliding shoe 20, threaded cap 50, handle 51 and spring 11 that frame 10 is arranged from top to bottom, its mid frame 10 vertical direction has blind round hole, frame 10 horizontal direction has square blind hole, pull bar 30 is cylindric and slides in blind round hole, sliding shoe 20 is rectangular-shaped and slides in square blind hole, have the first through hole in the middle part of pull bar 30 and on the downside of the first through hole, inwall have the first wedge surface, in the middle part of sliding shoe 20, correspondence is provided with the second wedge surface, sliding shoe 20 outer end has been wholely set screw rod, threaded cap 50 one end is connected with screw flight and end face and frame 10 sidewall offset, threaded cap 50 other end is connected by pin with handle 51, locating piece 21 is bumped into blind round hole upper end, locating piece 21 center has the second through hole slided for pull bar 30, pressing plate 31 is socketed in pull bar 30 upper end and also and between pull bar 30 passes through nut check, between spring 11 is fixed on bottom square blind via bottom and pull bar 30, locating piece 21 central protuberance has positioning boss, and positioning boss is circumferentially with chamfering, pull bar 30 upper end is provided with axle journal, and pressing plate 31 is socketed on axle journal.
During use, workpiece 40 is placed on locating piece 21, then forward drive handle 51, thus drive threaded cap 50 to rotate forward, and then drive sliding shoe 20 outwards movement, and then pass through the cooperation of the second wedge surface, the first wedge surface, drive pull bar 30 to overcome spring 11 resistance and move down, thus workpiece 40 compresses by band dynamic pressure plate 31.
After machining, reverse drive handle 51, thus drive threaded cap 50 to rotate backward, and then drive sliding shoe 20 to move inward, pull bar 30 moves up under spring 11 acts on, thus unclamps workpiece 40.
