Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, specifically a sheet metal laser cutting worktable with automatic positioning function. Background Technology

[0002] Sheet metal work is a comprehensive cold-working process for thin metal sheets (typically less than 6mm). According to international professional journals, this process includes various processing methods such as shearing, punching / cutting / combined cutting, bending, riveting, splicing, and forming (e.g., car bodies). A significant characteristic of sheet metal parts is that the thickness of the same part remains consistent, and its cutting process typically requires specialized cutting equipment.

[0003] In actual production, laser cutting of sheet metal parts faces a significant problem: since the cutting path is preset by the program, if the workpiece is not placed correctly, the actual cutting position will deviate from the design trajectory, resulting in dimensional errors or shape deformation. Currently, the common practice is to manually adjust the sheet metal parts to the correct position on the worktable. This method is not only inefficient but also consumes a large amount of labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a sheet metal laser cutting worktable with automatic positioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sheet metal laser cutting worktable with automatic positioning function, including

[0007] A support mechanism includes a support base, a plurality of support cones uniformly fixedly connected to the top of the support base, a plurality of through openings uniformly opened inside the support base, a support frame provided below the support base, hydraulic rods being fixedly connected through the four corners inside the support frame, the output ends of each set of hydraulic rods being fixedly connected to the support base, a plurality of crossbars uniformly fixedly connected inside the support frame, a support rod being fixedly connected to the top of each set of crossbars, the support rods passing through the through openings, and ball bearings being movably connected to the top of each set of support rods.

[0008] A positioning mechanism includes a positioning frame slidably connected to the outer side of the support base, an adjusting screw rotatably connected inside the positioning frame, the adjusting screw being threadedly connected to the support base, a first stepper motor fixedly connected to one side of the positioning frame, the output end of the first stepper motor being fixedly connected to one end of the adjusting screw, a positioning plate fixedly connected to one side of the top of the support base, a stop fixedly connected to the top of the positioning frame, a double-acting screw rotatably connected to the top of the stop, a central push plate symmetrically threaded to the outer side of the double-acting screw, and a second stepper motor fixedly connected to one side of the stop, the output end of the second stepper motor being fixedly connected to one end of the double-acting screw.

[0009] As a further embodiment of this utility model: guide rods are symmetrically slidably passed through the inside of the support frame, and each set of guide rods is fixedly connected to the support base.

[0010] As a further embodiment of this utility model: a guide rod is slidably passed through one side of the support base, and the guide rod is fixedly connected to the positioning frame.

[0011] As a further embodiment of this utility model: multiple reinforcing ribs are uniformly fixedly connected to the side of the positioning plate away from the baffle, and each group of reinforcing ribs is fixedly connected to the support base.

[0012] As a further embodiment of this utility model: guide strips are slidably connected to the bottom of the two sets of central push plates, and the guide strips are fixedly connected to the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With the above-described structure, this invention utilizes the coordinated operation of a first stepper motor, a hydraulic rod, a second stepper motor, and a centering push plate. When the hydraulic rod starts working, it drives the support frame, crossbar, and support rod to move up and down, thereby moving the sheet metal part placed on top of the support cone. This allows the ball bearings to support the sheet metal part. The first stepper motor, when started, moves the support base and positioning plate until the sheet metal part is in contact with the positioning plate and the stop. The second stepper motor, when started, drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two sets of centering push plates to move relative to each other, pushing the sheet metal part to the center. This achieves automatic positioning of the sheet metal part, significantly reducing the labor intensity of workers compared to the traditional method of manually moving the sheet metal part for positioning and adjustment.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figure 1-4 A sheet metal laser cutting worktable with automatic positioning function includes a support mechanism 1. The support mechanism 1 includes a support base 101, and multiple support cones 102 are uniformly fixedly connected to the top of the support base 101. The support cones 102 are used to support sheet metal parts. Multiple through holes 103 are uniformly opened inside the support base 101. A support frame 104 is provided below the support base 101. Hydraulic rods 105 are fixedly connected to the four corners of the support frame 104. The output end of each set of hydraulic rods 105 is fixedly connected to the support base 101. The hydraulic rods 105 are used to drive the support frame 104 to move up and down when starting work.

[0023] Guide rods 108 symmetrically slide through the interior of the support frame 104. Each set of guide rods 108 is fixedly connected to the support base 101. The guide rods 108 are used to guide the up-and-down movement of the support frame 104. Multiple crossbars 106 are evenly fixedly connected inside the support frame 104. A support rod 107 is fixedly connected to the top of each set of crossbars 106. The support rod 107 passes through the through-hole 103. The crossbars 106 and the support rod 107 move up and down synchronously with the support frame 104, so that the support rod 107 can lift and support the sheet metal parts on the support cone 102. A ball bearing 109 is movably connected to the top of each set of support rods 107. The ball bearing 109 facilitates the movement of the sheet metal parts at the top.

[0024] The positioning mechanism 2 includes a positioning frame 201 slidably connected to the outer side of a support base 101. An adjusting screw 202 is rotatably connected inside the positioning frame 201 and threadedly connected to the support base 101. The adjusting screw 202 is configured to cause the support base 101 to slide within the positioning frame 201 during rotation. A guide rod 204 slidably passes through one side of the support base 101 and is fixedly connected to the positioning frame 201. The guide rod 204 guides the movement of the support base 101.

[0025] A first stepper motor 203 is fixedly connected to one side of the positioning frame 201. The output end of the first stepper motor 203 is fixedly connected to one end of the adjusting screw 202. The first stepper motor 203 is configured to drive the adjusting screw 202 to rotate during startup. A positioning plate 205 is fixedly connected to one side of the top of the support base 101. The positioning plate 205 is configured to limit one side of the sheet metal part. Multiple reinforcing ribs 206 are evenly fixedly connected to the side of the positioning plate 205 away from the stop 207. Each set of reinforcing ribs 206 is fixedly connected to the support base 101. The reinforcing ribs 206 are configured to further connect and fix the positioning plate 205 to the support base 101, thereby improving the connection stability between the positioning plate 205 and the positioning frame 201.

[0026] A stop 207 is fixedly connected to the top of the positioning bracket 201. The stop 207 is used to limit the movement of the sheet metal part on the other side. A double-acting screw 208 is rotatably connected to the top of the stop 207. A centering push plate 209 is symmetrically threaded to the outer side of the double-acting screw 208. The double-acting screw 208 is used to drive the two sets of centering push plates 209 to move relative to or away from each other when rotating, thereby pushing the sheet metal part to the center position.

[0027] Guide bars 210 are slidably connected to the bottom of the two sets of centering push plates 209. The guide bars 210 are fixedly connected to the baffle 207, and the guide bars 210 are used to guide the movement of the centering push plates 209. A second stepper motor 211 is fixedly connected to one side of the baffle 207. The output end of the second stepper motor 211 is fixedly connected to one end of the bidirectional screw 208. The second stepper motor 211 is used to drive the bidirectional screw 208 to rotate when starting work.

[0028] In use, the sheet metal part to be cut is placed on top of the support cone 102. Then, each set of hydraulic rods 105 is activated, causing the hydraulic rods 105 to drive the support frame 104 upward. This causes the support frame 104 to drive each set of crossbars 106 and each set of support rods 107 upward until each set of support rods 107 drives each set of ball bearings 109 to lift the sheet metal part. Next, the first stepper motor 203 is activated, causing the first stepper motor 203 to drive the adjusting screw 202 to rotate. When the adjusting screw 202 rotates, it can drive the support base 101 and the sheet metal part supported by the ball bearings 109 to move towards one side of the stop 207. After the sheet metal part moves to contact the stop 207, the stop... The frame 207 can limit the position of the sheet metal part. Then, as the support base 101 moves, the positioning plate 205 moves to contact the other side of the sheet metal part. Then, the second stepper motor 211 is started, which drives the bidirectional screw 208 to rotate when it starts working. When the bidirectional screw 208 rotates, it drives the two sets of centering push plates 209 to move relative to each other, thereby pushing the sheet metal part to the center. Then, the hydraulic rod 105 is started again, which extends the hydraulic rod 105 and drives the bracket 104, the crossbar 106 and the support rod 107 to move downward until the sheet metal part moves downward to contact the support cone 102, thereby completing the automatic positioning of the sheet metal part.
