Description

Technical Field

[0001] The utility model relates to the technical field of origin positioning, in particular to a novel positioning origin structure. Background Art

[0002] Sheets are widely used in the machinery industry and have a wide range of applications. When processing sheets on various machine tools (such as automatic drilling machines, automatic tapping machines, CNC milling machines, tapping and milling machining centers, machining centers, etc.), the sheets must be firmly and accurately fixed on the workbench of the machine tool in advance to ensure that the sheets are in a stable, accurate and non-displacement state on the workbench.

[0003] Due to unstable or inaccurate plate fixation, displacement and shaking are likely to occur during the processing, resulting in deviations between the processed size, shape, etc. and the design requirements. Due to the generation of processing errors, the processed plates may not meet the standards and requirements and become defective products, which not only wastes raw materials and processing costs, but may also delay production progress and reduce production efficiency. Improper plate fixation may suddenly loosen or fly out during processing, causing physical harm to operators and even leading to serious safety accidents. Utility Model Content

[0007] Furthermore, the cylinder assembly includes a cylinder barrel and a piston, the positioning switch is arranged on the inner side of the bottom end of the cylinder barrel, the bottom end of the piston is fixedly connected to the top of the Z-axis screw rod, the side end of the X-axis screw rod is slidably connected to the side wall of the cylinder barrel, and the side end of the X-axis screw rod is arranged at the side wall of the cylinder barrel. The piston descends along the inner wall of the cylinder barrel, and the movement of the piston pushes the Z-axis screw rod connected thereto.

[0008] Furthermore, the outer side of the piston is slidably connected to the inside of the cylinder, and when the gas pressure acts on the piston, the piston descends along the inner wall of the cylinder.

[0009] Furthermore, the high-precision swing switch also includes a slot area and a block. The slot area is arranged on the front side of the positioning switch. The rear side of the top end of the swing block is rotatably connected to the front side of the positioning switch, and the bottom end of the block rotates, thereby pushing the positioning element to move toward the side of the workbench and approach the product.

[0012] Compared with the prior art, the present invention provides a new positioning origin structure with the following beneficial effects:

[0013] This new positioning origin structure moves the positioning switch, lowers the cylinder, and then the Z-axis lead screw and X-axis lead screw are combined to approach the product. When the high-precision switch is turned on, the side positioning is completed. The equipment automatically determines the workpiece origin, which significantly reduces the processing scrap rate caused by human operation errors, effectively saves costs, and improves resource utilization. Both the left and right sides of the product can be used as processing origins, which increases the flexibility and convenience of operation, adapts to various processing needs, improves production efficiency, realizes the automation of the positioning process, and avoids the sudden loosening or flying out of the plate during processing due to improper fixation, which helps to ensure the consistency and stability of processing accuracy.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0021] like Figure 1-Figure 5 As shown, a new positioning origin structure includes a workbench 1, and positioning switches 2 are slidably connected to the two ends of the top side of the workbench 1. The top of the positioning switch 2 is movably connected to a cylinder assembly 3, and the internal bottom end of the cylinder assembly 3 is movably connected to a Z-axis screw rod 4. The bottom of the Z-axis screw rod 4 is fixedly connected to the top of the positioning switch 2. An X-axis screw rod 5 is provided at the side wall of the cylinder assembly 3. A high-precision swing switch 6 is movably connected to the side wall of the positioning switch 2. A positioning element 7 is provided at the bottom end of the high-precision swing switch 6. The high-precision swing switch 6 includes a swing block 62, and the bottom end of the swing block 62 is fixedly connected to the top of the positioning element 7. The inner side of the high-precision swing switch 6 is rotatably connected to the side wall of the positioning switch 2. The side wall of the X-axis screw rod 5 is located above the table top of the workbench 1.

[0022] like Figure 1 As shown, the overall structure of the cylinder assembly 3, the Z-axis screw rod 4 and the X-axis screw rod 5 are located at both ends of the workbench 1 and are arranged in a group in opposite directions, and can move toward the middle along the top side of the workbench 1;

[0023] like Figure 1-Figure 3As shown, the cylinder assembly 3 includes a cylinder barrel 31 and a piston 32, the positioning switch 2 is arranged on the inner side of the bottom end of the cylinder barrel 31, the bottom end of the piston 32 is fixedly connected to the top of the Z-axis screw rod 4, the side end of the X-axis screw rod 5 is slidably connected to the side wall of the cylinder barrel 31, the side end of the X-axis screw rod 5 is arranged at the side wall of the piston 32, and the outer side of the piston 32 is slidably connected to the inside of the cylinder barrel 31. The cylinder assembly 3 starts working, and the inside of the cylinder barrel 31 is filled with gas. When the gas pressure acts on the piston 32, the piston 32 descends along the inner wall of the cylinder barrel 31, and the movement of the piston 32 pushes the Z-axis screw rod 4 connected thereto, causing it to run to the corresponding position. Example 2:

[0024] like Figure 1 and Figure 5 As shown, the high-precision swing switch 6 also includes a slot area 61 and a block 63. The slot area 61 is arranged on the front side of the positioning switch 2, and the rear side of the top end of the swing block 62 is rotatably connected to the front side of the positioning switch 2. The front end of the block 63 is fixedly connected to the rear end side wall of the swing block 62, and the rear end of the block 63 is slidably connected to the inner side of the slot area 61. When the swing block 62 inside the high-precision swing switch 6 rotates and swings, the inner end of the block 63 and the slot area 61 are connected, and the bottom end of the block 63 rotates, thereby pushing the positioning element 7 to move toward the side part of the workbench 1 and close to the product, thereby realizing the side positioning of the product.

[0025] Working principle: Figure 1-Figure 5 As shown, first, place the product on the table 1;

[0026] Then, the positioning switch 2 is driven by the electric drive to move to the corresponding position to determine the initial position of the product or trigger subsequent actions;

[0027] Next, the cylinder assembly 3 starts working. The cylinder barrel 31 is filled with gas. When the gas pressure acts on the piston 32, the piston 32 descends along the inner wall of the cylinder barrel 31. The movement of the piston 32 pushes the Z-axis screw rod 4 connected to it, causing it to move to the corresponding position.

[0028] After the Z-axis screw rod 4 is in place, it drives the X-axis screw rod 5 to lower the table surface close to the workbench 1. After that, the X-axis screw rod 5 moves quickly to the vicinity of the product and slows down to slowly approach the product;

[0029] When the swing block 62 inside the high-precision swing switch 6 rotates and swings, the inner end of the clamping block 63 and the clamping slot area 61 are connected, and the bottom end of the clamping block 63 rotates, thereby pushing the positioning element 7 to move toward the side of the workbench 1 and close to the product, thereby realizing the side positioning of the product.
