Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal grinding and bending fixture for sheet metal processing. Background Technology

[0002] Sheet metal processing refers to the process of processing metal sheets, mainly including methods and process parameters such as shearing, punching, and bending. It is a core technology that sheet metal technicians need to master and an important process for forming sheet metal products.

[0003] The bending of sheet metal involves the use of a grinding device to grind the sheet metal parts. In this process, the grinding is usually done manually by hand using a hand grinder. However, since there is no limiting device on the outside of the sheet metal parts, the parts are prone to displacement, making the grinding process quite tiring. Therefore, a grinding fixture for bending sheet metal is proposed to solve the above-mentioned problems. Utility Model Content

This solves the problem that in the process of bending sheet metal, grinding is usually done manually by hand with a grinding machine. However, during the grinding process, the lack of a limiting device on the outside of the sheet metal parts makes it easy for the sheet metal parts to shift, resulting in a laborious grinding process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the embodiments, by Figure 1-4 This invention discloses a sheet metal grinding and bending fixture for sheet metal processing. The fixture includes a grinding plate 1, a connecting frame 2 fixedly connected to the top of the grinding plate 1, a linear transmission assembly 3 fixedly connected to the right end of the connecting frame 2, a connecting plate 4 fixedly connected to the bottom end of the linear transmission assembly 3, a U-shaped frame 5 fixedly connected to the bottom end of the connecting plate 4, a telescopic cylinder 6 fixedly connected to the outside of the U-shaped frame 5, a telescopic box 7 fixedly connected to the outside of the telescopic end of the telescopic cylinder 6, an elastic assembly 8 fixedly connected to the inside of the telescopic box 7, a pressing plate 9 fixedly connected to the outside of the elastic assembly 8, and a bending sheet metal part 10 snapped between the pressing plate 9 and the U-shaped frame 5.

[0027] Among them, a protective pad 11 is fixedly connected to the top of the grinding plate 1, and a connecting pad 12 is fixedly connected to the outside of the U-shaped frame 5. The connecting pad 12 and the outside of the protective pad 11 are pressed against each other.

[0028] The protective pad 11, together with the connecting pad 12, can protect the outer side of the bent sheet metal part 10, effectively preventing damage to the bent sheet metal part 10.

[0029] The linear transmission assembly 3 includes a linear motor 31 fixedly connected to the right end of the connecting frame 2. A linear threaded rod 32 is fixedly connected to the outside of the output shaft of the linear motor 31. A movable sleeve 33 is connected to the outside of the linear threaded rod 32 through threaded transmission.

[0030] Starting the linear motor 31 causes the linear threaded rod 32 to rotate, which in turn drives the moving sleeve 33 to move left and right.

[0031] Among them, the top end of the movable sleeve 33 is fixedly connected to the limiting rod 13, the outer side of the limiting rod 13 is slidably connected to the inner side of the connecting frame 2, and the top end of the limiting rod 13 is fixedly connected to the sliding plate.

[0032] The limiting rod 13 can restrict the movement of the movable sleeve 33, effectively preventing the movable sleeve 33 from shifting position during movement.

[0033] The elastic component 8 includes an elastic spring 81 fixedly connected to the inside of the telescopic box 7, and an elastic plate 82 fixedly connected to the other end of the elastic spring 81. The outer side of the elastic plate 82 is fixedly connected to the outer side of the pressing plate 9.

[0034] The elastic component 8 allows the pressing plate 9 to move left and right.

[0035] Among them, there are multiple elastic springs 81, an elastic rod 14 is fixedly connected to the inner side of the telescopic box 7, the outer side of the elastic rod 14 is slidably connected to the inner side of the elastic plate 82, and there are multiple telescopic cylinders 6.

[0036] Working principle:

[0037] When it is necessary to fix the bent sheet metal part 10, the outer side of the bent sheet metal part 10 is placed inside the U-shaped frame 5. Then, the telescopic cylinder 6 is activated to move the telescopic box 7 left and right. By moving the position of the pressing plate 9, the outer side of the bent sheet metal part 10 can be fixed, which makes it convenient to grind the outer side of the bent sheet metal part 10.

[0038] Simultaneously starting the linear motor 31 causes the linear threaded rod 32 to rotate, which in turn drives the movable sleeve 33 to move left and right, allowing the position of the U-shaped frame 5 to be changed, thus increasing the overall flexibility of the device.
