Description
Technical Field
The utility model relates to a hold-down mechanism, especially an automatic compensation hold-down mechanism for welding frock.
Background
The welding piece needs to be compressed tightly through the welding frock earlier in welding process, and welding process product spare is easy to take place to warp, so the compressing tightly of control product spare can play important role to the welding quality of product spare. Some product pieces which are welded through laser are compressed by a plurality of compressing mechanisms, however, in the welding process, when a welding gun reaches a compressing point, the compression arm needs to be opened, the welding gun is clamped again after passing, and otherwise, the laser welding gun interferes with the compression arm. The problems with the above process are: on one hand, the consistency of the welding seam cannot be guaranteed, and on the other hand, a plurality of pressing mechanisms are opened and closed in sequence and need to occupy more time, so that the production efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve prior art's problem, provide an automatic compensation hold-down mechanism with adjustment packing force, adopt the mechanism can improve weld gap's uniformity to improve production efficiency.
The problem of the utility model is solved with following technical scheme:
the utility model provides an automatic compensation hold-down mechanism, install on compressing tightly the frock, including compressing tightly the cylinder mount pad, compress tightly the cylinder, the fixed connection block, the slide wedge connecting block, the V-arrangement movable block, the wedge slider, the briquetting, spring and bolt, it is fixed with compressing tightly the frock to compress tightly the cylinder through compressing tightly the cylinder mount pad, the fixed connection block rigid coupling compresses tightly the cylinder, compress tightly the cylinder piston rod and connect the V-arrangement movable block, the front end at the fixed connection block is fixed to the slide wedge connecting block, spring suit is on the bolt, bolt and spring pass the slide wedge connecting block, the V-arrangement movable block, bolt lower extreme and wedge slider threaded connection, wedge slider lower part rigid coupling briquetting, the briquetting touches and presses product spare.
According to the automatic compensation pressing mechanism, the inclined plane of the wedge connecting block is symmetrical to the inclined plane of the wedge sliding block, the V-shaped movable block is located between the wedge connecting block and the wedge sliding block, and the V-shaped movable block is in matched contact with the inclined planes of the wedge connecting block and the wedge sliding block.
According to the automatic compensation pressing mechanism, the middle part of the V-shaped movable block is provided with the through groove, the bolt penetrates through the through groove, and the transverse size of the through groove is larger than the diameter of the bolt.
Above-mentioned automatic compensation hold-down mechanism, the bolt sets up two side by side, is equipped with the draw-in groove on each bolt, installs the snap ring spacing to the spring in the draw-in groove.
Hold-down mechanism uses with the cooperation of conventional hold-down mechanism, if when ordinary hold-down mechanism need open in welding process, because the packing force changes, the high production fluctuation that can produce of compressing tightly of product spare, automatic compensation hold-down mechanism can automatic adjustment packing force this moment, compensates the difference in height of product spare. The utility model has the advantages as follows: 1. by automatically compensating the pressing force, the problem that the consistency of a welding gap cannot be ensured due to the fact that the pressing arm is opened in the welding process of the traditional pressing device is solved, and the first-time qualified rate of products is improved; 2. the effect of small output force of the cylinder and larger pressing force can be realized by adopting the force transmission principle of the wedge; 3. the number of conventional strict mechanisms in the welding tool can be reduced, the simplification of tool actions is realized, and meanwhile, the welding efficiency is also improved.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a perspective view of the present invention.
The reference numbers in the figures are: 1. v-arrangement movable block, 1-1, lead to the groove, 2, slide wedge connecting block, 3, bolt, 4, spring, 5, fixed connection piece, 6, compress tightly the cylinder, 7, compress tightly the cylinder mount pad, 8, compress tightly the frock, 9, snap ring, 10, wedge slider, 11, briquetting, 11, product spare.
Detailed Description
Referring to fig. 1 and 2, the utility model discloses a compensation is including compressing tightly cylinder mount pad 7, compressing tightly cylinder 6, fixed connection piece 5, slide wedge connecting block 2, V-arrangement movable block 1, wedge slider 10, briquetting 11, spring 4 and bolt 3. The pressing cylinder is fixed with the pressing tool 8 through a pressing cylinder mounting seat, and a fixing connecting block in a [ -shape is fixedly connected with the pressing cylinder. The piston rod of the pressing cylinder is connected with the V-shaped movable block to drive the V-shaped movable block to move transversely. The slide wedge connecting block is fixed at the front end of the fixed connecting block, the spring is sleeved on the bolt, the bolt and the spring penetrate through the slide wedge connecting block and the V-shaped movable block, the lower end of the bolt is in threaded connection with the wedge-shaped sliding block, the lower part of the wedge-shaped sliding block is fixedly connected with a pressing block 11, and the pressing block touches and presses a product part 12. The inclined plane of the wedge connecting block is symmetrical to the inclined plane of the wedge sliding block, the V-shaped movable block is located between the wedge connecting block and the wedge sliding block, and the V-shaped movable block is in matched contact with the inclined planes of the wedge connecting block and the wedge sliding block. The middle part of the V-shaped movable block is provided with a through groove 1-1, a bolt passes through the through groove, and the transverse size of the through groove is larger than the diameter of the bolt so as to reserve a moving space of the V-shaped movable block. The bolts are arranged in parallel, each bolt is provided with a clamping groove, and a clamping ring 9 for limiting the spring is arranged in each clamping groove.
The utility model discloses use with the cooperation of conventional hold-down mechanism. As shown in figure 1, when the piston rod of the pressing cylinder drives the V-shaped movable block to move right, the wedge-shaped sliding block is pushed to move downwards, so that the pressing block is pressed on a product piece. In the welding process, when the conventional pressing mechanism is opened and the product piece fluctuates in the vertical direction, the automatic compensation pressing mechanism can adjust the pressing force to enable the pressing block to press the product piece, and the height difference in the vertical direction is automatically compensated, so that the consistency of the welding line is kept. Furthermore, the utility model discloses a slide wedge passes the power principle, can realize the effect of the little output power of cylinder, obtain great packing force.
