Abstract
The utility model relates to the field of automobile body manufacturing, and provides a perforation positioning and clamping device, which comprises a cylinder, a drive rod, a support seat, a first crank, a second crank, a compressing piece and a positioning pin, wherein the cylinder is connected with the drive rod, the support seat, the first crank, the compressing piece and the second crank are sequentially hinged with one another to form a quadrilateral mechanism, and the drive rod is connected with the compressing piece. According to the perforation positioning and clamping device, a clamping mechanism is reconstructed, the compressing piece, the first crank, the second crank and the support seat are hinged with one another to form the quadrilateral mechanism, the compressing piece moves parallelly, so the work profile of the compressing piece is in a horizontal state all the time, the compressing piece and a workpiece which is clamped are ensured to be in surface contact, the impact of the pressing force to the workpiece and a compressing block is reduced, and the surface quality of the workpiece is improved.
Description
[technical field]
The utility model relates to vehicle body and makes the field, relates in particular to be used for the tight device of bodywork parts perforation positioning.
[background technology]
Japan SMC pneumatic element company releases a kind of tight composition element of bodywork parts perforation positioning that is exclusively used in, and sees shown in Figure 1.The power source apparatus of this assembly is the compact cylinder, use the rollback power of cylinder to clamp, the centre passs force mechanisms and clamping element fuses, and the guide effect of the gathering sill by the centre is converted into stretching out and returning action of cylinder compressing member opened and compress action.Its alignment pin plays the role of positioning to the hole of passing, and in compressing member open mode energy setback location key seat, makes things convenient for the turnover of workpiece.The compressing member of this device moves downward by gathering sill and forms a flip angle simultaneously and realize clamping function to workpiece.This will ask gathering sill and bearing pin that very high precision and hardness are arranged, and gathering sill and bearing pin have wearing and tearing all can cause the variation of the flip angle size of compressing member slightly, and the variation of flip angle directly causes compressing member work profile to contact with the caught workpiece line.Will influence like this and clamp stability and workpiece surface quality.
[utility model content]
In order to solve the problems of the prior art, the utility model provides a kind of perforation positioning clamping device, comprise cylinder, drive rod, supporting seat, first crank, second crank, compressing member, alignment pin, described cylinder is connected with described drive rod, described supporting seat, first crank, compressing member, second crank are hinged together successively and form a quadrangular mechanism, and described drive rod is connected with described compressing member.
As further improvement of the utility model, described supporting seat, first crank, compressing member, second crank are hinged together successively and form a parallel-crank mechanism.
As further improvement of the utility model, described drive rod is connected by the slotted hole that is arranged on described compressing member place with described compressing member.
As further improvement of the utility model, described slotted hole is the slotted hole that is inclined relative to horizontal.
As further improvement of the utility model, described slotted hole is that the angle that is inclined relative to horizontal is that 25 degree are to 40 degree.
As further improvement of the utility model, described slotted hole is that the angle that is inclined relative to horizontal is that 30 degree are to 35 degree.
The utility model is transformed clamp mechanism, compressing member, first crank, second crank and supporting seat be hinged together form a parallel-crank mechanism, compressing member is done parallel moving, the work profile that has so just guaranteed compressing member is level all the time, just can guarantee that compressing member and caught workpiece are that face contacts, alleviate the impact of thrust, improve the surface quality of workpiece workpiece and compact heap; This device makes the high-amplitude overturn structure of compressing member into hinge arrangement by a narrow margin, and motion is more reliable by a narrow margin, and it is littler to wear and tear; The junction of drive rod and compressing member is transferred in high-amplitude motion, and the wearing and tearing of the sum of errors of compressing member junction just can compensate by the stroke of cylinder like this, as long as the certain cylinder stroke of reservation just can not influence the operate as normal of this device; Improved the service life of compressing member and entire mechanism.The slotted hole of this device compressing member and drive rod junction is not level but inclination certain angle, and this angle helps moving, and guarantees the smooth and easy of this device motion.

[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Extremely shown in Figure 6 as Fig. 2, a kind of perforation positioning clamping device, comprise cylinder 1, drive rod 2, supporting seat 3, first crank 4, second crank 5, compressing member 6, alignment pin 7, described cylinder 1 is connected with described drive rod 2, described supporting seat 3, first crank 4, compressing member 6, second crank 5 are hinged together successively and form a parallel-crank mechanism, and described drive rod 2 is connected by the slotted hole that is inclined relative to horizontal that is arranged on described compressing member 6 places with described compressing member 6.Described slotted hole be the angle that is inclined relative to horizontal be 25 degree to 40 degree, preferred 30 degree are to 35 degree.
The utility model is transformed clamp mechanism, compressing member, first crank, second crank and supporting seat be hinged together form a parallel-crank mechanism, compressing member is done parallel moving, the work profile that has so just guaranteed compressing member is level all the time, just can guarantee that compressing member and caught workpiece are that face contacts, alleviate the impact of thrust, improve the surface quality of workpiece workpiece and compact heap; This device makes the high-amplitude overturn structure of compressing member into hinge arrangement by a narrow margin, and motion is more reliable by a narrow margin, and it is littler to wear and tear; The junction of drive rod and compressing member is transferred in high-amplitude motion, and the wearing and tearing of the sum of errors of compressing member junction just can compensate by the stroke of cylinder like this, need only us and reserve the operate as normal that certain cylinder stroke just can not influence this device; Improved the service life of compressing member and entire mechanism.
This device can be optimized design to each parts of this mechanism neatly according to the shape and the concrete size in the crossbeam hole of vehicle frame before and after the vehicle body of reality, uses very extensive.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
