Description
Technical field
The present invention relates to a kind of field of fixtures, be specifically related to a kind of plug-type clamping device.
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 plug-type clamping device 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: plug-type clamping device, comprises pedestal, link gear and clamp system, and described pedestal is provided with boss, transverse holes and vertical hole; Described link gear comprises power rail, gangbar and cam, and described power rail and transverse holes are slidably connected, and described gangbar and vertical hole are slidably connected, described cam and boss hinged, one end of described power rail and one end of gangbar are all hinged with cam; Described clamp system comprises the pressing plate for clamping brake rim, and middle part and the pedestal of described pressing plate are hinged, and one end of pressing plate is fixedly connected with gangbar.
The principle of base case and advantage: during operation, be first positioned on pedestal by brake rim; Then propulsion power bar left, the pin joint of power rail band moving cam on boss turns clockwise, and cam driven gangbar moves up, and gangbar band dynamic pressure plate moves up away from one end of clamping brake rim, and the other end of pressing plate and brake rim are offseted; Finally by pressing plate away from one end of gangbar and the upper end of brake rim offsets, the lower end of pedestal and brake rim offsets, and realizes the clamping to brake rim with this.Otherwise, then releasing of brake drum.This programme is mainly through propulsion power bar left, and coordinate the clamping that cam, gangbar and pressing plate realize brake rim, its overall structure is simple, easy to operate, effectively raises the operating efficiency to brake rim processing.
Preferred version one: based on the preferred version of scheme, described clamp system also comprises alignment pin and is arranged at the spacing hole on pedestal, described alignment pin and spacing hole are slidably connected, stage clip is provided with between described alignment pin and spacing hole, described alignment pin and pressing plate offset, by above-mentioned setting, because alignment pin and pressing plate offset, when platen clamp brake rim, stage clip is in impaction state, when clamp loose brake rim, stage clip promotes alignment pin and gives pressing plate for clamping one, one end thrust upwards of brake rim, accelerates the time of releasing of brake drum.
Preferred version two: the preferably preferred version of, described link gear also comprises connecting plate, described connecting plate connects power rail and cam, gangbar and cam, by above-mentioned setting, employing connecting plate instead of power rail and gangbar is direct and cam is hinged, effectively reduce the wearing and tearing between cam and power rail, gangbar, improve the service life of cam, power rail and gangbar.
Preferred version three: the preferably preferred version of two, described pressing plate is set to the projection of arc-shaped for the one end clamping brake rim, by above-mentioned setting, replace plane to the clamping of brake rim by projection, reduce contact area, significantly reduce the wearing and tearing to brake rim, and projection compares flat grip brake rim, impetus is more concentrated, also better to the clamping effect of brake rim.
Preferred version four: the preferably preferred version of three, described pin joint is all fixed by bearing pin, by above-mentioned setting, bearing pin make pressing plate and cam more stable when its pin joint rotates, and convenient for assembly and dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the plug-type clamping device 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: pedestal 1, boss 2, transverse holes 3, vertical hole 4, power rail 5, gangbar 6, cam 7, pressing plate 8, alignment pin 9, spacing hole 10, stage clip 11, connecting plate 12, projection 13, bearing pin 14.
Embodiment is substantially as shown in Figure 1: plug-type clamping device, comprises pedestal 1, link gear and clamp system, and pedestal 1 is provided with boss 2, transverse holes 3, vertical hole 4 and spacing hole 10; Link gear comprises power rail 5, gangbar 6, cam 7 and two connecting plates 12, power rail 5 and transverse holes 3 are slidably connected, gangbar 6 and vertical hole 4 are slidably connected, cam 7 is hinged by bearing pin 14 and boss 2, the left end of power rail 5 is fixedly connected with the right-hand member of connecting plate 12, the left end of connecting plate 12 and cam 7 are by hinge, and the lower end of gangbar 6 is fixedly connected with the upper end of another connecting plate 12, and lower end and the cam 7 of another connecting plate 12 pass through hinge; The alignment pin 9 that clamp system comprising pressing plate 8 for clamping brake rim, being slidably connected with spacing hole 10, the middle part of pressing plate 8 is hinged by bearing pin 14 and pedestal 1, the left end of pressing plate 8 is fixedly connected with gangbar 6, the right-hand member of pressing plate 8 is set to the projection 13 of arc-shaped, be provided with stage clip 11 between alignment pin 9 and spacing hole 10, and alignment pin 9 is arranged at the below of pressing plate 8 and pressing plate 8 offsets.
