Abstract
The utility model discloses a trolley positioning pin calibration instrument. The trolley positioning pin calibration instrument comprises a rectangular framework composed of a front surrounding rod, a rear surrounding rod, a left surrounding rod and a right surrounding rod, wherein the outer sides of the front surrounding rod, the left surrounding rod and the right surrounding rod are respectively provided with L-shaped positioning plates, a vertical lateral surface of each positioning plate is fixedly connected with the surrounding rods, a horizontal lateral surface of each positioning plate is provided with a positioning hole, two positioning plates are arranged at the outer side of the front surrounding rod, and the outer sides of the left surrounding rod and the right surrounding rod are respectively provided with one positioning plate. When positioning pins on a trolley deviate, the trolley positioning pin calibration instrument is installed on a calibration rail to calibrate the positioning pins, namely positioning and calibration are carried out on the positioning holes in the trolley positioning pin calibration instrument and the positioning pins of the trolley. The calibration accuracy is high, a trolley body can be positioned accurately, and the safety risks in the conveying process of the trolley body are eliminated.
Description
Technical field
The utility model relates to a kind of calibration instrument, relates in particular to a kind of chassis locating dowel pin calibration instrument.
Background technology
In the car production process, the application vehicle body is sent to general assembly PBS storage line and utilizes chassis to finish the conveying task, vehicle body relies on locating dowel pin and the location of the knock hole on the vehicle body on the chassis in the location on the chassis, the chassis that is loaded with vehicle body in the process of at every turn carrying back and forth vehicle body locating dowel pin because of stressed can the occurrence positions deviation, need after the occurrence positions deviation alignment pin position is calibrated, the alignment method of prior art is to calibrate with tape measure in alignment rail, this alignment method measured error is very large, be difficult to calibrate the position of locating dowel pin, thereby be difficult to guarantee that vehicle body accurately locates, cause easily the vehicle body knock hole can not accurately cooperate with the chassis locating dowel pin, cause in carrying the process of vehicle body vehicle body not steady, even the accident potential that exists descending to overturn.
The utility model content
Problem to be solved in the utility model is, the method error of the calibration chassis locating dowel pin of prior art is very large, is difficult to guarantee that vehicle body accurately locates, and has potential safety hazard.The utility model provides a kind of chassis locating dowel pin calibration instrument, can guarantee that vehicle body accurately locates, and eliminates the potential safety hazard of vehicle body in course of conveying.
The purpose of this utility model is achieved through the following technical solutions.A kind of chassis locating dowel pin calibration instrument, comprise the rectangular frame that is formed by front railing, rear railing, left railing and right railing, the outside of described front railing, left railing and right railing is respectively equipped with L shaped locating plate, the vertical side of locating plate is captiveed joint with railing, the horizontal side of locating plate is provided with knock hole, the described front railing outside is provided with two locatings plate, and left railing, the right railing outside are respectively equipped with a locating plate.When the locating dowel pin occurrence positions deviation on the chassis, at the calibration track chassis locating dowel pin calibration instrument being installed calibrates the locating dowel pin on the chassis, namely the knock hole on the chassis locating dowel pin calibration instrument and the locating dowel pin on the chassis are positioned calibration, this scheme calibration accuracy is high, can guarantee that vehicle body and chassis accurately locate, eliminate the potential safety hazard of vehicle body in course of conveying.
As preferably, be connected with stirrup on the left railing of described rectangular frame and the right railing.Stirrup is set can increase rectangular frame rigidity, avoids chassis locating dowel pin calibration instrument to deform, thereby guarantees the precision of calibrating.
As preferably, the outside of described left railing and right railing is respectively equipped with handle.This scheme handled easily.
The beneficial effects of the utility model are, guarantee that vehicle body accurately locates, and eliminate the potential safety hazard of vehicle body in course of conveying.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model locating plate.
The specific embodiment
The below is described in further detail the utility model in conjunction with the accompanying drawings and embodiments:
Extremely shown in Figure 2 such as Fig. 1, a kind of chassis locating dowel pin calibration instrument, comprise by front railing, rear railing, the rectangular frame 1 that left railing and right railing form, each railing can be the stock making of rectangle by cross-sectional plane, the outside of described front railing is fixedly connected with two L shaped locatings plate 2 with bolt and nut, left railing, the right railing outside is fixedly connected with respectively a L shaped locating plate 2 with bolt and nut, the vertical side of locating plate 2 is captiveed joint with railing, the horizontal side of locating plate is provided with circular knock hole 21, and the position of locating dowel pin is corresponding on the position of knock hole and the chassis.Be fixedly connected with stirrup 3 on the left railing of described rectangular frame and the right railing, the outside of described left railing and right railing is respectively equipped with rectangle handle 4.When the locating dowel pin occurrence positions deviation on the chassis, at the calibration track chassis locating dowel pin calibration instrument being installed calibrates the locating dowel pin on the chassis, namely the knock hole on the chassis locating dowel pin calibration instrument and the locating dowel pin on the chassis are positioned calibration, this scheme calibration accuracy is high, can guarantee that vehicle body and chassis accurately locate, eliminate the potential safety hazard of vehicle body in course of conveying.
The above is the better specific embodiment of the utility model, is not to limit practical range of the present utility model with this.The utility model can also have other embodiment, and only otherwise deviate from spirit of the present utility model, no matter in form what kind of conversion all drops within the protection domain of the present utility model.
