The alleged problem of the present invention solves by the following technical programs:
A kind of multi-vehicle-type positioner that is used for auto production line, its special feature is: it comprises base, loam cake, expansion link, alignment pin, slide, expansion link spring and slide spring, described expansion link spring, expansion link, alignment pin are arranged in the base aperture from the bottom to top, the expansion link middle part is provided with inversed taper platform, set pin sleeve is contained in expansion link top and is supported by expansion link inversed taper platform upper surface, described slide is combined by split block, each split block obvolvent expansion link inversed taper platform, described slide spring along base radially roof pressure between base and split block.
The above-mentioned multi-vehicle-type positioner that is used for auto production line, described loam cake is fixed on base top, and loam cake is to the unidirectional axial limiting of alignment pin.
The above-mentioned multi-vehicle-type positioner that is used for auto production line, the bottom surface of described slide is supported by the stage end face of base upper hole, the maximum outside diameter coupling after the aperture at this place and slide are opened.
The above-mentioned multi-vehicle-type positioner that is used for auto production line, described slide is involuted by four split blocks, and slide is in the internal diameter and the alignment pin bottom external diameter coupling of its top step hole of obvolvent state.
The above-mentioned multi-vehicle-type positioner that is used for auto production line, the external diameter coupling of the aperture of described base bottom hole and expansion link spring.
The present invention is directed to auto production line NC numerical control navigation system complex structure, manufacturing and the high problem of maintenance cost and improve, designed a kind of positioner that can be used for multi-vehicle-type.This device is arranged on the auto production line, its alignment pin can be flexible according to the distribution situation of different workpieces locating hole, no locating hole place alignment pin is depressed by workpiece, and the location of locating hole place alignment pin realization to workpiece arranged, and has realized auto production line multi-vehicle-type product flexible production thus.Compare with existing NC numerical control navigation system, that the present invention has is simple in structure, be easy to that realization, manufacturing and maintenance cost are low, characteristics such as little take up room.

Label is as follows in the accompanying drawing: 1. base, 1-1, base upper hole, 1-2. base bottom hole, 2. expansion link spring, 3. expansion link, 3-1. inversed taper platform, 4. slide spring, 5. slide, 5-1. split block, 5-2. slide top step hole, 6. loam cake, 7. alignment pin, 8. workpiece.
The specific embodiment
Referring to Fig. 1, Fig. 2, the present invention's formation comprises base 1, loam cake 6, expansion link 3, alignment pin 7, slide 5, expansion link spring 2 and slide spring 4.Be provided with up big and down small notch cuttype endoporus in the base, expansion link spring, expansion link, alignment pin are arranged in the base aperture from the bottom to top, the aperture of base bottom hole 1-2 and the external diameter of expansion link spring coupling.The expansion link bottom presses at expansion link spring top, is provided with inversed taper platform 3-1 at the expansion link middle part, and alignment pin 7 is sleeved on expansion link top and is supported by the upper surface of expansion link inversed taper platform.Described slide 5 is combined by four split block 5-1, slide inner conical surface and inversed taper platform male cone (strobilus masculinus) outline, each split block around inversed taper platform with its obvolvent, the bottom external diameter coupling of the internal diameter of slide its top step hole 5-2 when open mode not and alignment pin 7.The slide bottom surface is supported by the stage end face of the maximum endoporus 1-1 of base upper diameter, the maximum outside diameter coupling after the aperture of base upper hole 1-1 and slide are opened.The slide spring along base radially roof pressure between base and split block,, all be provided with the spring stopper slot with split block installation slide spring place at base for avoiding slide spring displacement.Loam cake 6 is fixed on base top, and the stage of loam cake endoporus defines alignment pin and moves upward alignment pin 7 axial limitings.Figure 1 shows that the schematic diagram that slide is not opened, alignment pin is in running order; Figure 3 shows that expansion link 3 moves down under external force, slide 5 is backed down, and alignment pin 7 moves down the schematic diagram that is in off working state.
Referring to Fig. 1, Fig. 3, Fig. 4, the present invention is used for the multi-vehicle-type production line, is fixed in the position of different automobile types locating hole.If certain vehicle workpiece 8 has locating hole at A positioner place, when B positioner place does not have locating hole, workpiece moves downward the expansion link 3 of depressing the B positioner, move downward with expansion link, inversed taper platform 3-1 backs down slide 5, each split block 5-1 footpath of slide is outwards moved, and the slide hole is increased until greater than alignment pin 7 bottom external diameters, and alignment pin 7 is fallen in the base; And the expansion link of A positioner and alignment pin pass the locating hole of workpiece, and workpiece is located.After processing, workpiece moves upward, the pressure of B dowel device expansion link disappears, and expansion link spring 2 promotes expansion link and moves upward, and expansion link promotes alignment pin and moves upward, the split block of slide to axe movement, is blocked spacing up to alignment pin by loam cake 6 under the effect of slide spring simultaneously.
