Description

Technical Field

[0001] This utility model relates to the field of sheet metal grooving and positioning technology, and more specifically, to a workpiece grooving and positioning fixture. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts.

[0003] Currently, V-grooves need to be cut into the surface of sheet metal. The purpose of grooving is to reduce the stress of subsequent bending and improve the bending effect. The existing method is to set up a gantry on the processing table, and install a drive component connected to the grooving cutter on the gantry. The drive component drives the grooving cutter to move along multiple axes to perform grooving. However, the positioning effect is not good for sheet metal of different sizes, which makes the sheet metal prone to positional displacement during the subsequent grooving process. At the same time, a lot of debris will accumulate on the processing table during the grooving process, which is not aesthetically pleasing and can easily affect the subsequent grooving effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a workpiece slotting and positioning fixture.

The vacuum adsorption assembly is located in the central area of ​​the processing table; The first track is fixed on the processing table, and a positioning rod is welded on the first track; The slide grooves are symmetrically opened on the processing table, and a second track, which is connected to the drive component and is distributed parallel to and opposite to the first track, slides in the slide grooves. There are two sliders that slide together on the first track and the second track, respectively; Several threaded holes are respectively opened on the first track and the second track, and the slider is provided with a fixing bolt that mates with one of the threaded holes; The pressure-down component is located on each slider; The debris collection and extraction assembly is set on the processing table and is located outside the first track.

A mounting slot, matching the size of the adsorption box, is provided on the processing table; The adsorption box is fixed in the mounting groove and is flush with the surface of the processing table. Several suction holes are provided on the adsorption box; The vacuum pump is fixed on the processing table, and the input pipeline of the vacuum pump passes through the processing table and the mounting slot and is connected to the inside of the adsorption box.

[0007] Furthermore, the drive assembly includes a fixed plate, a first screw, a sliding block, and a handwheel. The fixing plate is fixed on the processing table, and the fixing plate is threadedly connected to the first screw.

[0008] Furthermore, the pressing assembly includes a mounting plate, a second screw, a throttle, and a pressing column. The mounting plate is welded onto each slider; The second screw is threadedly connected to the mounting plate. The throttle is fixed to one end of the second screw, and the other end of the second screw is fixed to a pressure post.

This ensures that the sheet metal is firmly positioned and will not shift during subsequent grooving. At the same time, this fixture can effectively collect the generated debris into the collection box during grooving, so that a large amount of debris will not accumulate on the processing table. This not only improves the appearance but also does not affect the subsequent grooving process, resulting in a better grooving effect for the sheet metal. Attached Figure Description

[0017] To reduce wear on the sheet metal during the pressing and fixing process, the above embodiment is further optimized by providing a rubber layer on the pressing column.

[0019] In a further optimization of the above embodiment, a side door is rotatably connected to the collection box 113 via a hinge. The side door is not shown in the figure. The side door and the collection box 113 are specifically connected by electromagnetic adsorption. That is, the collection box has a groove, a first magnet is provided in the groove, a second magnet that cooperates with the first magnet is provided on the side door, and a sealing element is provided on the inner edge of the side door. The sealing element is not shown in the figure.

[0020] It should be noted that both the vacuum pump and the air pump 115 are electrically connected to the controller, which is not labeled in the figure.

[0021] The working process of this utility model is as follows: First, the sheet metal to be slotted is placed in the middle area of ​​the processing table 1. Initially, the second track 6 is moved away from the vacuum adsorption component 2 by the drive component 5 and the slide 4, so as not to affect the placement of the sheet metal. During the placement process, the positioning rod 31 limits the placement position of the sheet metal (that is, the sheet metal is parallel to the processing table 1 after placement). At the same time, the sheet metal can completely cover the adsorption box 22. Then, the vacuum pump is controlled by the controller to effectively adsorb the middle area of ​​the sheet metal. After the sheet metal completes the vacuum adsorption in the middle area, slide the two sliders 7 on the first track 3 to move the two sliders 7 to the two corners of one side of the sheet metal and lock them. Then rotate the handle 103 to make the pressure column 104 descend and limit the pressure position of the two corners of the sheet metal. Then, by turning the handwheel 54, the second track 6 is driven to approach the other side of the sheet metal. When the two sets of pressing components 10 on the slider 7 of the second track 6 move to the edge above the other side of the sheet metal, the handwheel 54 is stopped. Then, the two sliders 7 on the second track 6 are slid so that the two sliders 7 move to the remaining two corners of the sheet metal and lock. Then, by operating the throttle 103, the four corners of the sheet metal can be positioned. This creates a positioning effect of vacuum adsorption in the middle area of ​​the sheet metal and pressing down and fixing the four corners of the edges. This can firmly limit the position of sheet metal of different sizes to avoid positional displacement during the subsequent grooving process. Then the grooving process can begin. At the same time, the air pump 115 is controlled by the controller to work. At this time, the debris generated by grooving can be effectively sucked into the collection box 113 through the suction hood 111 and the conveying pipe 112. Then the debris adheres to the filter element 114. After a batch of sheet metal grooving is completed, the side door is opened to clean and replace the filter element 114.
