Technical Field

The utility model relates to a location technical field that punches a hole specifically is a car sheet metal component auxiliary positioning frock that punches a hole.

Background

The sheet metal part is a product processed by a sheet metal process, and the sheet metal part cannot be separated everywhere in life. The sheet metal part is manufactured by filament power supply winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precise welding, roll forming, sheet metal bending forming, die forging, water jet cutting and precise welding. Along with the more and more extensive application of panel beating, the design of sheet metal component has become a very important ring in the product development process, and mechanical engineer must skilled master the design skill of sheet metal component for the panel beating of design both satisfies the requirements such as function and the outward appearance of product, can make stamping die make simple, with low costs again.

But car sheet metal component top press die directly pushes down the lower mould when punching a hole and carries out the punching press, because sheet metal component itself is thinner, if the small size punching press hole is intensive leads to punching press hole edge deformation burr easily in the punching press, leads to the inaccurate right with top press die easily in the time of fixed sheet metal component moreover, leads to the skew of punching a hole.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a car sheet metal component auxiliary positioning frock that punches a hole has solved when punching a hole if the small size is a large amount of easy deformation and the machined part position that punches a hole and the problem that top punching press drill bit does not correspond of punching a hole.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an automobile sheet metal component auxiliary positioning frock that punches a hole, includes workstation and support frame, the support frame is all installed to workstation top surface both sides, the fixed support column that is equipped with in support frame one side, support column top movable mounting has the punching press board, workstation top surface movable mounting has the punching press platform, and the punching press platform both ends can be dismantled with the support column and be connected, punching press bench top surface has seted up the punching press hole, punching press downthehole bottom fixed mounting has the spring, spring top fixedly connected with fore-set, the through hole has been seted up in punching press board surface run through, and the through hole is located punching press hole top, the through hole outside is fixed and is equipped with the cursor circle, the laser lamp is installed to the cursor circle inner.

Preferably, the two ends of the punching platform are both connected with sliders, the sliding groove is formed in one side of the supporting column, the sliders are located in the inner cavity of the sliding groove, and the two ends of the punching platform are detachably connected with the supporting column through the sliding groove and the sliders.

Preferably, a clamping groove is formed in one side of the top of the supporting column, clamping seats are connected to two ends of the stamping plate, and the clamping seats are located in the clamping groove inner cavity.

Preferably, the top end of one side of the support frame is penetrated and inserted with a positioning pin, and the positioning pin penetrates through the clamping seat.

Advantageous effects

The utility model provides a car sheet metal component auxiliary positioning frock that punches a hole. The method has the following beneficial effects:

1. this auxiliary positioning frock punches a hole, the spring that the inner chamber through the punching press hole set up, the spring top is connected with the fore-set, the fore-set carries out the activity to the bottom surface of machined part and supports, so can not be because the bottom that the machined part need punch a hole does not support when leading to punching a hole easy deformation when the punching press drill bit at top carries out the punching press, the inner chamber wall that punches a hole is more burr and deformation influence quality like this, and when the drill bit returns back because the elastic support of spring will the fore-set top home position, then make the rim charge that punches off continue to be located the inner chamber that punches a hole in the middle of, can avoid needing the punching press porous in a less district like this, when punching press void area is big because punching press intensity and sheet metal part itself are thin to.

2. This auxiliary positioning frock punches a hole is equipped with the cursor circle through the outside of through hole, and the laser lamp is installed to the inner chamber of cursor circle, and the laser lamp shines out the cursor of circle towards the bottom machined part like this, makes its and the mark that the machined part surface need the punching press to be done reference the contrast, just so can see clearly whether the machined part position is placed the accuracy, avoids the skew to lead to punching a hole failure.

3. This auxiliary positioning frock punches a hole, spout and slider through the L type through the punching press platform carry out demountable installation with the support column, conveniently change the punching press platform like this, because the diameter of punching a hole of the product of different models is different, it is convenient like this to change the punching press platform, thereby the punching press board passes through the card seat card and goes into the draw-in groove inner chamber and then fix through the locating pin and support column demountable installation, thereby conveniently change the punching press board of different diameter through holes, better cost has been reduced like this, only need to change punching press board and punching press platform.
