Abstract
The utility model relates to a three-jaw locating clamping mechanism for welding an automobile body in white. The three-jaw locating clamping mechanism for welding the automobile body in white comprises a workpiece locating pin, a clamping mechanism and a driving mechanism. The driving mechanism is connected with the clamping mechanism and the clamping mechanism is connected with the workpiece locating pin; the driving mechanism drives the clamping mechanism to open and after a workpiece is placed in the clamping mechanism, the workpiece is located through the end face of the workpiece locating pin, and then the driving mechanism drives the clamping mechanism to clamp the workpiece tightly. Compared with the prior art, the three-jaw locating clamping mechanism for welding the automobile body in white has the advantages of being stable in locating clamping, low in cost, short in machining time and the like.
Description
Technical field
The utility model relates to a kind of Automobile Welding fixture, especially relates to a kind of three-jaw positioning and clamping mechanism for the automobile body-in-white welding.
Background technology
The auto industry equipment is to rise recently an also emerging industry of fast development.It also exists before this in fact, but because the vehicle of automobile factory is changed not now so frequent, kind variation so, and vehicle to change when changing maximum be exactly body in white.The conversion that this just requires its corresponding welding line can catch up with automotive type and kind.Give prominence in this case welding line in automobile production and the effect in making, made people more and more pay attention to it.On the Automobile Welding streamline, the workload that really is used for welding operation only accounts for 30%～40%, and 60%～70% be the auxiliary and clamping work of workpiece.Because the clamping of workpiece is completed on weld jig, so fixture plays an important role in whole welding process.
At present, in the automobile body-in-white welding field, a lot of occasions need to adopt finger setting and with the mechanism that clamps, we are referred to as the peg type clamping cylinder.Much more general the use on the automotive floor panel position.Because its workpiece is larger, porose in the middle of workpiece, in the time of the location, hole, need to clamp simultaneously near the position, hole.During this time just send with the peg type clamping cylinder of positioning and clamping mechanism and gone up use.Traditional commercial peg type clamping cylinder model is single, and mechanism is complicated, and delivery date is longer, and is on the high side, annotates the cycle as the need spy longer.When being used for Workpiece clamping, single clamping head makes the state of Workpiece clamping stable not.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of the location to clamp the three-jaw positioning and clamping mechanism that is used for the automobile body-in-white welding stable, that cost is low, process time is short for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of three-jaw positioning and clamping mechanism for the automobile body-in-white welding comprises workpiece alignment pin, clamp mechanism and driving mechanism, and described driving mechanism is connected with clamp mechanism, and described clamp mechanism is connected with the workpiece alignment pin;
Driving mechanism drives clamp mechanism and opens, and after workpiece was put into clamp mechanism, the end face by the workpiece alignment pin positioned, and then driving mechanism drives clamp mechanism and starts and clamp.
Described clamp mechanism is provided with a plurality of.
Described clamp mechanism comprises clamp arm and workpiece tray, and described clamp arm is connected with driving mechanism, and after putting into workpiece, clamp arm and workpiece tray are interlocked.
Described workpiece alignment pin is circular alignment pin.
Described workpiece alignment pin is provided with the skewed slot for the clamp arm motion.
Described driving mechanism is straight-line cylinder.
Compared with prior art, the utlity model has following advantage:
One, the effect of the location of this mechanism clamping is better than commercial peg type clamping cylinder, and Workpiece clamping power branch is even, positioning stablity;
Two, the cost of this mechanism is lower than commercial peg type clamping cylinder, and the external diameter of alignment pin and clamp jaw can be set flexibly according to the workpiece shape;
Three, except processing voluntarily as all parts the common cylinder that drives, the cycle is short.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is motion schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite take technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 1-shown in Figure 2, a kind of three-jaw positioning and clamping mechanism for the automobile body-in-white welding comprises workpiece alignment pin 1, clamp mechanism and driving mechanism 4, and described driving mechanism 4 is connected with clamp mechanism, and described clamp mechanism is connected with workpiece alignment pin 1.
Described workpiece alignment pin 1 is circular alignment pin, and described clamp mechanism is provided with a plurality of, and scattering device is around the workpiece alignment pin.Described clamp mechanism comprises clamp arm 2 and workpiece tray 3, and described clamp arm 2 is connected with driving mechanism 4, and after putting into workpiece 5, clamp arm 2 and workpiece tray 3 are interlocked, clamping work pieces 5.Described workpiece alignment pin 1 is provided with the skewed slot for the clamp arm motion.Described driving mechanism 4 is straight-line cylinder.
The operation principle of above-mentioned three-jaw positioning and clamping mechanism for automobile body-in-white welding is that air cylinder driven clamp arm 2 is opened, as shown in phantom in Figure 2, after the body of a motor car workpiece drops into, by the pin face location of workpiece alignment pin 1, after cylinder intake, clamp mechanism starts clamping, completes the location.After weld job, open clamp mechanism, take out workpiece, complete welding.
