Description
Technical field
The present invention relates to field of fixtures, be specifically related to a kind of clamping device of brake rim.
Background technology
In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed before processing, clip.Fixture is made up of setting element, clamping device, tool setting induction element, indexing means, Connection Element and clamp body etc. usually.Fixture and grip device are widely known by the people, and are widely used for manufacturing.Particularly, fixture has various reference surface and point, and parts or instrument can accurately be located.In many process, this is general to clamp member, so that these parts can keep correct juxtaposition relationship in such as punching press, riveted joint, welding, the process of pasting or solidifying.
Brake rim is the ironcasting of the similar tambourine of a kind of shape, and it and tire are fixed and synchronized rotation.Use oil pressure to promote brake shoes contact brake rim inner edge during brake, the friction produced by contact suppresses the rotation of tire to reach the object of brake.Drum brakes is made up of the relevant connecting rods such as shoe sole, wheel cylinder, brake shoes, spring, tip nail, brake rim.At present only commonly be used in trailing wheel.The cost of drum brakes is lower, absolute brake Li Genggao, is more used in the trailing wheel of pony car.Along with the development of Chinese national economy, also growing to the demand of brake rim, according to different demand, brake rim needs for further processing, therefore the fixture for processing brake rim is of crucial importance, the usual overall structure of existing fixture is more complicated, operates more loaded down with trivial details, reduces the operating efficiency to brake rim processing.
Summary of the invention
The invention is intended to provide the clamping device of the brake rim that a kind of structure is simple, easy to operate, operating efficiency is high.
Achieve the above object, base case of the present invention is as follows: the clamping device of brake rim, comprises pedestal, clamp system and driving mechanism, is provided with the first shoulder hole, the second shoulder hole and the 3rd shoulder hole in described pedestal, described clamp system comprises circular cope match-plate pattern and lower bolster, for clamping the left jaw of brake rim and right jaw, described lower bolster is arranged in the first shoulder hole, described cope match-plate pattern is arranged at the top of lower bolster and is fixedly connected with pedestal, upper groove is provided with in described cope match-plate pattern, on the sidewall of described upper groove, left and right is arranged with positioning convex, low groove is provided with in described lower bolster, described upper groove is relative with low groove and be connected, described left jaw, right jaw is equipped with pilot hole, described left jaw, the pilot hole of right jaw is all slidably connected with its positioning convex, described left jaw, right jaw is away from side walls hinged all with low groove of one end of clamping brake rim, described driving mechanism comprises the drive rod be arranged at through the second shoulder hole, the 3rd shoulder hole in low groove, for driving the rotating disk of drive rod movement, described drive rod is provided with external screw thread away from one end of low groove and is connected with rotating disk, described drive rod is provided with chute, described pedestal is provided with the limit screw for the movement of stop drive rod, described limit screw and chute are oppositely arranged, and described rotating disk is fixedly connected with pedestal.
The principle of base case: during operation, is first positioned on cope match-plate pattern by brake rim, then rotating disk is rotated clockwise, because drive rod one end away from low groove is provided with external screw thread and is connected with rotating disk, driven by rotary disc drive rod moves down, drive rod drives lower bolster to move down away from one end of rotating disk, due to left jaw, right jaw is away from side walls hinged all with low groove of one end of clamping brake rim, and left jaw, the pilot hole of right jaw is all hinged with its positioning convex, left jaw and right jaw are moved down, when the upper end of positioning convex and pilot hole offsets, left jaw, right jaw all offsets with brake rim away from one end of low groove, limit screw is driven to offset near one end of drive rod and chute, all offset with brake rim away from one end of low groove finally by left jaw, right jaw, offseting of cope match-plate pattern and brake rim, realizes the clamping to brake rim.Otherwise, then unclamping brake rim is realized.
The advantage of base case: this programme moves down mainly through rotating driven by rotary disc drive rod, coordinate the clamping of lower bolster, jaw, positioning convex and limit screw realization to brake rim, its overall structure is simple, easy to operate, effectively raises the operating efficiency of processing brake rim.
Preferred version one: based on the preferred version of scheme, stage clip is provided with in described second shoulder hole, described stage clip is arranged between lower bolster and pedestal, by above-mentioned setting, stage clip has very strong compression capability, and when rotating disk drives drive rod to move down, drive rod drives lower bolster to move down, make left jaw and the clamping of right jaw realization to brake rim, stage clip is in impaction state; Otherwise stage clip gives lower bolster one thrust upwards, effectively decrease the time of left jaw and right jaw releasing of brake drum.
Preferred version two: the preferably preferred version of, described rotating disk is provided with the handle for rotating rotating disk, by above-mentioned setting, handle is adopted to replace rotating disk to drive drive rod to move up and down, have more feel, more laborsaving, effectively decrease the time of clamping brake rim, further increase the operating efficiency of processing brake rim.
Preferred version three: the preferably preferred version of two, described cope match-plate pattern is fixedly connected with pedestal by bolt, and by above-mentioned setting, bolt effectively limits cope match-plate pattern and the movement of pedestal on level, vertical direction, and convenient for assembly and dismounting.
Preferred version four: the preferably preferred version of three, described left jaw, right jaw are away from side walls hinged all by bearing pin and low groove of one end of clamping brake rim, by above-mentioned setting, bearing pin makes left jaw, right jaw all more stable when its pin joint rotates, and convenient for assembly and dismounting.
