Description

Technical Field

[0001] The invention relates to the field of sheet metal processing, in particular to a sheet metal processing fixture. Background Art

[0002] Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for the formation of sheet metal products. Sheet metal processing includes traditional cutting, punching, bending and pressing methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, and new stamping technologies and new processes. The processing of sheet metal parts is called sheet metal processing. During the sheet metal clamping process, a certain amount of smoke and dust will be generated. The existing sheet metal processing clamping device has a simple structure and does not have a dust suction component, which leads to a chaotic clamping environment and affects the efficiency of sheet metal processing. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a sheet metal processing fixture, which has the advantages of solving the problems raised in the above background technology.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A sheet metal processing fixture comprises a base, a clamping groove is provided on the top surface of the base, a clamping assembly is provided in the clamping groove, and the clamping assembly comprises a two-way cylinder arranged at the center position of the clamping groove, output ends on both sides of the two-way cylinder extend to both sides, and slide blocks are fixedly connected to the output ends on both sides of the two-way cylinder, the bottom of the slide block is slidably matched with the clamping groove, the top of the slide block is vertically fixedly connected to a limit plate, the top of the limit plate extends to the outside of the clamping groove, a clamping block is fixedly connected to the adjacent side of the extended end of the limit plate, the clamping blocks are symmetrically arranged, symmetrical limit grooves are provided on adjacent sides of the clamping blocks, threaded holes are provided on the top of the limit grooves, and limit assemblies are provided in the threaded holes. One side of the clamping groove is located at the top of the base and is vertically fixedly connected to a baffle, and the baffle is provided with a movable groove on one side close to the limit plate, and a movable block is slidably matched in the movable groove, and a driving component is provided in the movable groove to drive the movable block to move left and right, and a dust suction component is provided on the side of the movable block close to the limit plate, and the dust suction component includes a dust suction head arranged on one side of the movable block, one end of the dust suction head is connected to a dust suction pipe, and the dust suction pipe is connected to a dust collecting box on the side away from the dust suction head, and the dust collecting box is fixedly connected to the top of the baffle, and a box cover is hinged on the top of the dust collecting box, and a filter screen is slidably matched in the dust collecting box, and activated carbon bags are placed between multiple filter screens, and one side of the multiple filter screens is located in the dust collecting box and an exhaust fan is embedded therein.

[0005] By adopting the above technical solution, during operation, the operator places the sheet metal between the limit plates on the top of the base according to the operation requirements. At this time, the operator turns on the two-way cylinder and cooperates with the output ends on both sides to drive the sliders to move toward each other according to the length requirements of the sheet metal, until the limit plates move toward each other to a suitable spacing position. At this time, the operator respectively embeds the two sides of the sheet metal into the limit grooves on the adjacent side of the clamping block, and cooperates with the limit components on the limit grooves to clamp and fix the two sides of the sheet metal. During the processing of the sheet metal, a certain amount of smoke and dust will be generated. At this time, the operator turns on the exhaust fan to form pressure, and the smoke and dust generated during the operation are adsorbed into the dust box through the cooperation of the dust suction pipe and the dust suction head, and filtered and blocked through multiple filters in the dust box. Finally, the setting of the activated carbon bag is used to adsorb harmful gases in the air, thereby meeting the emission standards and improving the working environment.

[0006] It is further configured that the limiting assembly includes a limiting screw threadedly connected to a threaded hole, the bottom of the limiting screw is rotatably connected to a limiting seat, and the bottom of the limiting seat is fixedly connected with a plurality of anti-slip protrusions.

[0007] By adopting the above technical solution, when both sides of the sheet metal are embedded in the limit grooves on the adjacent side of the clamping block, the operator simultaneously turns the limit screws to drive the limit seat to move downward to cooperate in pressing and fixing the two sides of the sheet metal. When the bottom of the limit seat contacts the surface of the sheet metal, the friction between the sheet metal and the sheet metal can be increased by setting multiple anti-slip bumps, thereby improving the anti-slip effect.

[0008] Further configuration: the plurality of anti-slip protrusions are all made of rubber material.

[0009] By adopting the above technical solution, multiple anti-skid protrusions made of rubber material are in contact with the surface of the sheet metal part, thereby increasing the friction force and protecting the surface of the sheet metal part.

[0010] Further configuration: the driving assembly includes fixed seats arranged on both sides of the movable groove, a screw rod is rotatably connected between the fixed seats, the movable block is matched and connected to the outside of the screw rod, one end of the screw rod extends to the outside of the movable groove, and the extended end of the screw rod is connected to a servo motor through a coupling.

[0011] By adopting the above technical solution, during the vacuuming operation, the operator turns on the servo motor to drive the screw to rotate. At this time, the moving block on the screw and other components on the moving block cooperate with the moving groove to move back and forth left and right, thereby completing the adsorption and collection of dust generated during the operation.

[0012] It is further configured that fixing blocks are arranged around the outer side wall of the base, fixing holes are opened on the fixing blocks, and fixing rods are threadedly connected in the fixing holes.

[0013] By adopting the above technical solution, the fixing hole on the fixing seat cooperates with the fixing rod, which makes it easy for the operator to install the entire equipment and plays a certain stabilizing role.

[0014] In summary, the present invention has the following beneficial effects: When the present invention is in operation, the operator places the sheet metal between the limit plates on the top of the base according to the operation requirements. At this time, the operator turns on the two-way cylinder and cooperates with the output ends on both sides to drive the moving blocks to move toward each other according to the length requirements of the sheet metal, until the limit plates move toward each other to a suitable spacing position. At this time, the operator respectively embeds the two sides of the sheet metal into the limit grooves on the adjacent side of the clamping block, and cooperates with the limit components on the limit grooves to clamp and fix the two sides of the sheet metal.

[0015] During the processing of the present invention, a certain amount of smoke and dust will be generated. At this time, the operator turns on the exhaust fan to form pressure, and the smoke and dust generated during the operation are adsorbed into the dust collecting box through the cooperation of the dust collection pipe and the dust collection head. The smoke and dust are filtered and blocked through multiple filters in the dust collecting box. Finally, the activated carbon bag is set to adsorb harmful gases in the air, thereby meeting the emission standards and improving the working environment. BRIEF DESCRIPTION OF THE DRAWINGS
