Description

Technical Field

[0001] This utility model relates to the field of CNC panel sawing, specifically to an auxiliary tooling for precise positioning and calibration of CNC panel saw boards. Background Technology

[0002] CNC panel saws are advanced panel processing equipment that integrates mechanics, electrical systems, and CNC technology. They achieve high-precision and high-efficiency panel cutting through automated control and are widely used in furniture manufacturing, building decoration, and other fields. They are the mainstream equipment in the panel processing industry.

[0003] A search revealed a utility model patent with publication number CN214561570U, specifically disclosing a multi-functional CNC panel saw, relating to the field of CNC panel saw technology. This multi-functional CNC panel saw includes a base, with two sets of columns mounted on the top outer surface of the base. A crossbeam is welded to the top outer surface of the two sets of columns, and an electric guide rail is fixedly mounted on the top of the crossbeam. A mounting slide is slidably mounted on the electric guide rail, and a first guide rail is fixedly mounted on the front outer surface of the crossbeam. This multi-functional CNC panel saw, through the coordinated use of the crossbeam, electric guide rail, protective cover, electric guide rail controller, mounting base, mounting slide, first guide rail, and first slider, can move the mounting slide left and right for processing, facilitating the cutting and processing of irregularly shaped workpieces. This effectively enhances the practicality of the device, eliminating the need for manual hand-held cutting, avoiding unsightly workpieces, improving processing efficiency, and eliminating the safety hazards of hand-held cutting machines.

[0004] In order to improve processing efficiency, existing CNC panel saws typically stack multiple groups of boards and cut them simultaneously during the board cutting process. However, to ensure dimensional uniformity, the boards are usually stacked and placed against the edge of the machine's table before cutting to keep them aligned on the same vertical plane. But this method requires constant adjustment of the boards' positions during cutting to obtain the desired shape and size. As a result, the boards inevitably shift during movement, requiring constant recalibration. Furthermore, the need for manual calibration makes the board cutting process cumbersome and complex.

[0005] Therefore, it is necessary to invent an auxiliary tooling for precise positioning and calibration of CNC panel saws to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary tooling for precise positioning and calibration of CNC panel saws. By having positioning plate one and positioning plate two simultaneously move towards different sides of the panel, the stacked panels are aligned, thus solving the problems of easy panel shifting during cutting and cumbersome alignment in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tooling for precise positioning and calibration of CNC panel saws, comprising a base, a push plate provided on one side of the upper part of the base, a guide rod symmetrically installed on one side of the push plate and the guide rod being connected through to one side of the upper part of the base, a bolt rotatably connected to one side of the push plate and screwed to one side of the upper part of the base, and two sets of movable seats symmetrically arranged on both sides of the base.

[0008] The drive assembly set in the base includes a through cavity, which is symmetrically opened in the lower part of the base. Two sets of through cavities are rotatably connected to a worm gear. A servo motor is installed on one side of the base, and the output end of the servo motor is connected to the worm gear shaft.

[0009] The calibration and positioning component located on one side of the movable base includes a slider. The slider is symmetrically installed on the side of the movable base away from the base. A positioning plate two is provided on one side of the movable base. The upper part of the inner wall of the positioning plate two is symmetrically provided with sliding grooves, and the sliding grooves are slidably connected to the corresponding sliders.

[0010] Preferably, the drive assembly further includes a screw, which is threaded through and screwed to the end of the worm gear away from the servo motor. Both sets of through cavities are rotatably connected to rotating shafts, and worm wheels are sleeved and fixed on both sets of rotating shafts, with the worm wheels meshing with the worm gear.

[0011] Preferably, each of the two sets of rotating shafts is symmetrically connected with a second screw, and the threads of the second screws on both sides are opposite. The second screw is threaded through to the lower part of the corresponding movable seat. Each set of movable seats is symmetrically installed with a second guide rod, and the second guide rod is slidably connected through to the upper part of the base.

[0012] Preferably, each of the movable seats in each group is equipped with a trapezoidal block on its upper part, and the inclined surface of each trapezoidal block faces the base.

[0013] Preferably, the calibration positioning assembly further includes a positioning plate one, which is disposed on the side of the base away from the push plate. The positioning plate one is limited and connected through the screw one. A spring one is sleeved on the screw one, and the two sides of the spring one are respectively attached to one end of the screw one and the side of the positioning plate one away from the base. A guide rod three is symmetrically installed on the positioning plate one, and the guide rod three is connected through the lower part of the base.

[0014] Preferably, each of the two positioning plates in each group is symmetrically rotatably connected to a connecting cylinder at its lower part, each of the two connecting cylinders is slidably connected to a connecting rod, and each of the two connecting rods is fixedly connected to the lower part of the base. Each of the two connecting rods is screwed with a nut, and each of the two connecting rods is sleeved with a spring, and the two sides of the spring are respectively attached to the nut and the connecting cylinder.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] A servo motor drives a worm gear to rotate, causing screw one and screw two to work simultaneously. This causes positioning plates one and two to move towards different sides of the stacked materials, aligning them. This structure ensures stability of the materials during the cutting process, preventing offsets that could affect the cut dimensions. It also effectively avoids the need for repeated calibrations, as calibration only requires pre-adjustment of parameters to automatically position and calibrate the materials, reducing operational complexity and significantly improving the efficiency and quality of material cutting.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-7 The CNC panel saw's precision positioning and calibration auxiliary tooling includes a base 001, a push plate 101 on one side of the upper part of the base 001, a guide rod 102 symmetrically installed on one side of the push plate 101, and the guide rod 102 is connected through to one side of the upper part of the base 001. A bolt 103 is rotatably connected to one side of the push plate 101, and the bolt 103 is screwed to one side of the upper part of the base 001. Two sets of movable seats 104 are symmetrically arranged on both sides of the base 001.

[0029] The rotation of bolt 103 can drive the push plate 101 to move, and the guide rod 102 can ensure the stable movement of the push plate 101, so that the push plate 101 can push the side of the board to be stacked and cut to align, and the area of ​​the stacked board needs to be larger than the area of ​​the base 001, but cannot exceed the position of the moving seat 104, and the overall tooling is suitable for CNC panel saws with the main saw located above.

[0030] The drive assembly 002 located in the base 001 includes a through cavity 201. The through cavities 201 are symmetrically opened in the lower part of the base 001. The two through cavities 201 are rotatably connected to the worm gear 202. A servo motor 203 is installed on one side of the base 001, and the output end of the servo motor 203 is shaft-connected to the worm gear 202.

[0031] The servo motor 203 can drive the worm gear 202 to rotate within the through cavity 201.

[0032] The calibration and positioning component 003, which is located on one side of the movable base 104, includes a slider 304. The slider 304 is symmetrically installed on the side of the movable base 104 away from the base 001. A positioning plate 2 305 is provided on one side of the movable base 104. The upper part of the inner wall of the positioning plate 2 305 is symmetrically provided with a sliding groove 306, and the sliding groove 306 is slidably connected to the corresponding slider 304.

[0033] Through the cooperation of the groove 306 and the slider 304, the positioning plate 305 can slide and rotate on one side of the moving seat 104.

[0034] Furthermore, in the above structure, the drive assembly 002 also includes a screw 204, which is threaded through and screwed to the end of the worm gear 202 away from the servo motor 203. A rotating shaft 205 is rotatably connected through both sets of through cavities 201. A worm wheel 206 is sleeved and fixed on both sets of rotating shafts 205, and the worm wheel 206 meshes with the worm gear 202.

[0035] The rotation of the worm gear 202 can drive the screw 204 to move, and at the same time, the rotation of the worm gear 202 can drive the worm wheel 206 to rotate, thereby causing the rotating shaft 205 to rotate within the through cavity 201.

[0036] Furthermore, in the above structure, both sets of rotating shafts 205 are symmetrically connected with screws 207, and the screws 207 on both sides have opposite thread directions. The screws 207 are threaded through to the lower part of the corresponding movable seat 104. Each set of movable seats 104 is symmetrically equipped with guide rods 208, and the guide rods 208 are slidably connected through to the upper part of the base 001.

[0037] By setting the threads of the two sets of screws 207 on the rotating shaft 205 in opposite directions, the rotating shaft 205 can drive the moving seats 104 on both sides to move in opposite directions during the rotation process, while the guide rod 208 can ensure that the moving seats 104 move more smoothly.

[0038] Furthermore, in the above structure, each set of movable seats 104 is equipped with a trapezoidal block 209 on its upper part, and the inclined surface of each set of trapezoidal blocks 209 faces the base 001.

[0039] The trapezoidal block 209 allows the movable seat 104 to lift the stacked plates on the base 001 when it moves closer to the base 001, thus providing support and preventing damage to the base 001 during cutting.

[0040] Furthermore, in the above structure, the calibration positioning component 003 also includes a positioning plate 301. The positioning plate 301 is located on the side of the base 001 away from the push plate 101. The positioning plate 301 is limited and connected through the screw 204. A spring 302 is sleeved on the screw 204, and the two sides of the spring 302 are respectively attached to one end of the screw 204 and the side of the positioning plate 301 away from the base 001. Guide rods 303 are symmetrically installed on the positioning plate 301, and the guide rods 303 are connected through the lower part of the base 001.

[0041] The screw 204 can drive the positioning plate 301 to move to one side of the stacked boards, and cooperate with the push plate 101 to achieve the positioning of the boards. The spring 302 ensures that the movement of the screw 204 is not affected after the positioning plate 301 contacts the board. After the push plate 101 is positioned, the overall position of the board can be adjusted to effectively avoid the positioning plate 305 from coinciding with the cutting position.

[0042] Furthermore, in the above structure, each group of positioning plates 305 is symmetrically and rotatably connected to a connecting cylinder 307 at its lower part. Each group of connecting cylinders 307 is slidably connected to a connecting rod 308, and each group of connecting rods 308 is fixedly connected to the lower part of the base 001. Each group of connecting rods 308 is screwed with a nut 309, and each group of connecting rods 308 is sleeved with a spring 310. The two sides of the spring 310 are respectively attached to the nut 309 and the connecting cylinder 307.

[0043] The movable seat 104 moves towards the base 001. At this time, the connecting cylinder 307 slides along the connecting rod 308, so that the second spring 310 is gradually compressed during continuous movement. This causes the second positioning plate 305 to gradually rotate and fit against one side of the stacked plates, so that the plates overlap. The position of the second positioning plate 305 can be changed by rotating the nut 309 on the connecting rod 308, so that the rotation time of the second positioning plate 305 can be advanced or delayed. This facilitates the operation of the first positioning plate 301 under the same power source and avoids the situation where the first positioning plate 301 and the second positioning plate 305 are out of sync.

[0044] The working principle of this practical application is as follows:

[0045] Refer to the instruction manual appendix Figure 1-7By stacking the plates sequentially on top of the base 001, the position of the nut 309 is adjusted according to the size of the plates, thereby changing the force on the second spring 310. Simultaneously, the position of the push plate 101 is adjusted according to the size of the plates by rotating the bolt 103, ensuring the cutting position of the plates avoids the positioning plate 305. At this point, the servo motor 203 is activated, driving the worm gear 202 to rotate, which in turn drives the screw 204 to move the positioning plate 305, causing the positioning plate 301 to move closer to one side of the plates. Simultaneously, the worm gear 202, through the worm wheel 206, drives the screws 207 on both sides of the rotating shaft 205 to rotate, causing the moving seats 104 to move closer together. At the same time, the connecting cylinder 307 moves along the connecting rod 308, thus compressing the second spring 310. Under this compression, the positioning plate 305 gradually rotates. This allows the slide 306 to slide along the slider 304, and the trapezoidal block 209 to contact and support the bottom plate as the moving seat 104 moves closer together. Finally, positioning plate one 301 and positioning plate two 305 simultaneously contact the side of the plate, so that each group of plates is neatly stacked in sequence. The entire workpiece is then pushed into the position below the CNC panel saw, and positioning plate two 305 needs to be aligned with the moving direction of the main saw for subsequent cutting. This structure can stabilize the plate during the cutting process, avoid deviation during cutting, and prevent problems with the cutting dimensions. It also effectively avoids the need for repeated calibration, and during calibration, only the parameters need to be adjusted in advance to automatically position and calibrate the subsequent plates, reducing the complexity of operation and greatly improving the efficiency and quality of plate cutting.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
