Abstract
The utility model relates to a positioning pin structure used for automobile manufacturing and specifically relates to a clamping positioning pin mechanism used on a testing fixture. The mechanism includes a positioning face fixed on a base. A positioning pin is arranged on the positioning face. The positioning pin is of a hollow structure. The side face of the positioning pin is in communication with the inside hollow. A pressing part is arranged in the positioning pin. A pressing mechanism used for controlling the pressing part is arranged beneath the pressing part. Driven by the pressing mechanism, the pressing part presses a to-be-tested plate part on the positioning face so that testing precision is improved and unfavorable effects brought by testing errors on automobile manufacturing are prevented.
Description
Technical field
The utility model relates to a kind of automobile making locating pin structure, is specifically related to the clamping and positioning pin mechanism using in a kind of cubing.
Background technology
Body in white is in welding process, that numerous plates are welded into a body in white, by organic, reasonably form various sub-units, assembly, a body in white assembly of final formation, its process can be summarized as the process of " changeable ", therefore in process, need corresponding cubing to measure sub-unit, assembly, judge that whether the parts that weld out are qualified.According to the designing requirement of product, also need corresponding assembly, the sub-unit mass property of welding to measure, whether the product of judgement welding meets the requirements simultaneously, infers that whether welding process is controlled, stable.If met the requirements, continue to produce, if do not meet tolerance, according to the direction of deviation and position, carry out corresponding fixture adjustment, guarantee that product meets the requirements.The frock that body in white and corresponding assembly are measured is cubing.The structure of cubing generally has two register pins, corresponding a plurality of reference fields (being also locating surface).In actual measuring process, tested part is put into cubing, register pin need insert corresponding pilot hole.If placed, do not put in place, all measurement profile measurement piece, Location measurement pieces all cannot align (general deviation is larger, and people finds soon).But when register pin is put into position, reference field is not fitted (within 3mm), it measures profile measurement piece, Location measurement piece can align, but has had the deviation of 3mm, and general human eye cannot be found, thinks the deviation of part.Measurement data has just lost meaning like this.
Utility model content
The utility model, in order to solve in current automobile manufacturing process the accuracy problems existing in cubing measuring process, provides the clamping and positioning of using in a kind of cubing pin mechanism.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The clamping and positioning pin mechanism using in a kind of cubing, comprise the locating surface being fixed on pedestal, locating surface is provided with register pin, described register pin is hollow-core construction, the side of register pin and inner hollow communicating, in register pin, be provided with a compressing member, compressing member bottom is provided with for controlling the hold-down mechanism of compressing member.Hold-down mechanism can by plate to be measured tightly with locating surface laminating, lower with the test result degree of accuracy of avoiding plate to be measured and locating surface generation space to cause, to cause automobile body welding quality problems generation.
As preferably, locating surface has the positioning seat for being connected with pedestal, and positioning seat is hollow-core construction, and compressing member top is provided with a compression hook, and middle part is provided with an arcuate socket, and compressing member is positioned positioning seat by being positioned at the motion fixed pin of arcuate socket.Motion fixed pin is controlled compressing the position of hook, and to guarantee compressing hook, by motion fixed pin, the motion in arcuate socket realizes the control that board under test part is compressed and decontroled.
As preferably, described hold-down mechanism comprises connecting link, abutment ring and pressing handle, and the upper end of connecting link is connected with compressor arm lower end, and lower end is connected with one end of abutment ring, the other end of abutment ring is connected with the middle part of pressing handle, and the end of pressing handle is connected with pedestal.
As preferably, on pedestal, the center of corresponding connecting link is provided with a guide holder, and connecting link is positioned at guide holder, is positioned at guide holder top and is provided with a return fastener on connecting link, is provided with a retracing spring between return fastener and guide holder.Guide holder can carry out a guiding to connecting link on the one hand, prevents that connecting link from rocking, and causes fluctuation of service.Between return fastener and guide holder, form a closed screens, and retracing spring is carried out to space constraint, make when pressing handle moves downward, retracing spring is compressed, when pressing handle is opened, the screen resilience of retracing spring is convenient to pressing handle to open.
Owing to adopting technique scheme, the beneficial effects of the utility model are: make simple, cost is low, practical, and can under the effect of pressing handle, plate to be measured be pressed on locating surface, thereby improved the precision of test, the adverse effect of having avoided test error to bring automobile making.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model compressing member and hold-down mechanism.
In figure: 1 pedestal, 2 locating surfaces, 3 register pins, 4 compressing members, 5 hold-down mechanisms, 6 connecting links, 7 abutment rings, 8 pressing handles, 9 guide holders, 10 return fasteners, 11 retracing springs, 12 positioning seats, 13 compress hook, 14 arcuate sockets, 15 motion fixed pins.
Embodiment
With specific embodiment, the utility model is further described below.
Embodiment
The clamping and positioning pin mechanism using in a kind of cubing, as shown in Figure 1, comprise the locating surface 2 being fixed on pedestal 1, locating surface 2 is provided with register pin 3, described register pin 3 is hollow-core construction,, there is a compressing member 4 side of register pin 3 and inner hollow communicating in register pin 3, compressing member 4 bottoms with for controlling the hold-down mechanism 5 of compressing member 4, be connected.Hold-down mechanism 5 comprises connecting link 6, abutment ring 7 and pressing handle 8, the upper end of connecting link 6 is connected with compressing member 4 lower ends, lower end is connected with one end of abutment ring 7, and the other end of abutment ring 7 is connected with the middle part of pressing handle 8, and the end of pressing handle 8 is connected with pedestal 1.On pedestal 1, the center of corresponding connecting link 6 is provided with a guide holder 9, and connecting link 6 is positioned at guide holder 9, is positioned at guide holder 9 tops and is provided with a return fastener 10 on connecting link 6, is provided with a retracing spring 11 between return fastener 10 and guide holder 9.As shown in Figure 1, locating surface 2 has the positioning seat 12 for being connected with pedestal 1, positioning seat 12 is hollow-core construction, as shown in Figure 2, compressing member 4 tops are provided with a compression hook 13, middle part is provided with an arcuate socket 14, and compressing member 4 is positioned positioning seat 12 by being positioned at the motion fixed pin 15 of arcuate socket 14.The motion of motion fixed pin 15 in arcuate socket 14 can be controlled the action that compresses hook 13.
