Description

Technical Field

[0001] This utility model relates to the field of positioning devices, specifically a positioning device for drilling holes in sheet metal. Background Technology

[0002] Solid wood panels are a classic and popular choice in sofa manufacturing, known for their durability, natural beauty, and environmental friendliness.

[0003] The production process of solid wood boards typically includes the following steps: drying the wood, cutting the wood, sanding and trimming, tenoning and reinforcing, drilling, and assembling. Among these steps, drilling is mainly done by making holes in appropriate locations on the board to install components such as sofa legs and springs.

[0004] The current method of drilling boards typically involves placing them on a workbench to adjust their position before fixing them and drilling. However, during production and observation, it has been found that this method makes the board drilling process more complicated and increases the working time required for drilling.

[0005] Therefore, a board drilling and positioning device is proposed to address the above problems. Utility Model Content

The rotating wheel flattens the surface of the elastic wire, reducing the bending that occurs when the elastic wire contacts the plate. At the same time, the rotating wheel finally contacts the plate. The limiting component restricts the rotation direction of the rotating wheel, so that the limiting component is in a fixed state under the limiting action.

At this time, the second baffle will block the first baffle, reducing the situation where the rotating wheel reverses with the first baffle, and improving the stability of the rotating wheel when it squeezes the plate.

[0011] Preferably, a plurality of ball bearings are rotatably connected to the middle of the fixed rod; the ball bearings are arranged in an array; when the fixed rod slides along the slide groove, the ball bearings will also rotate under the contact action, the ball bearings will reduce the friction between the fixed rod and the slide groove, and reduce the wear of the fixed rod and the slide groove caused by friction.

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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, a plate drilling and positioning device includes a support platform 1; a drilling assembly 12 is provided on the top of the support platform 1; a motor 13 is fixedly connected to the inner side wall of the support platform 1; a screw 14 is fixedly connected to the output end of the motor 13; a sliding plate 15 is threadedly connected to the middle of the screw 14; the sliding plate 15 and the support platform 1 are slidably connected; a circular plate 16 is rotatably connected to the middle of the sliding plate 15; a support plate 17 is fixedly connected to the surface of the support platform 1; the circular plate 16 and the support plate 17 are rotatably connected; a plurality of sliding grooves 18 are opened in the middle of the circular plate 16; the sliding grooves 18 and the circular plate 16 are eccentrically arranged; a plurality of positioning blocks 19 are slidably connected to the surface of the support plate 17; the positioning blocks 19 are arranged in a circumferential array; a fixing rod 110 is fixedly connected to the bottom of the positioning blocks 19; the fixing rod 110 and the sliding grooves 18 are slidably connected; during operation, the plate is placed on the top of the support plate 17, and then the motor 13 can be started to make the screw 14 rotate. When the plate 14 rotates, the slide plate 15 will slide along the support platform 1, and the slide plate 15 will also rotate with the circular plate 16. When the circular plate 16 rotates, the slide groove 18 will rotate, and the fixing rod 110 will slide along the slide groove 18. The positioning block 19 will slide along the support plate 17 under the transmission action of the fixing rod 110. At this time, all positioning blocks 19 will move and move closer to the plate. The plate will be quickly fixed under the squeezing action of the positioning blocks 19. Because the positioning blocks 19 are circumferentially set, the plate will move under the squeezing action of the positioning blocks 19 and be located at the center of the support plate 17, realizing the device's rapid positioning of the support plate 17. Finally, the drilling component 12 can be activated to drill holes in it. When the slide plate 15 moves, the circular plate 16 will rotate with the slide groove 18 and the fixing rod 110 will slide along the support plate 17 with the positioning blocks 19, so that the positioning blocks 19 will move closer to the plate quickly, realizing the device's rapid positioning of the plate and improving the convenience of the device's positioning of the plate.

[0026] Please see Figure 4 As shown, a clamping plate 2 is symmetrically and rotatably connected to the center of the positioning block 19; multiple elastic wires 22 are fixed between adjacent clamping plates 2; before the positioning block 19 comes into contact with the plate, the elastic wires 22 will first come into contact with the plate. Because the elastic wires 22 are flexible elastic materials, they will deform first when they come into contact with the plate, causing the clamping plate 2 to rotate, and then elastically compress the plate, increasing the contact area between the device and the plate, while also reducing the direct contact between the plate and the positioning block 19; through the combined action of the clamping plate 2 and the elastic wires 22, the elastic wires 22 will first come into contact with the plate and compress it under elastic action, increasing the compression area of ​​the device on the plate, while also reducing the direct contact between the positioning block 19 and the plate, reducing the damage caused by excessive compression of the plate by the positioning block 19.

[0027] Please see Figure 4 and Figure 5As shown, a connecting plate 3 is fixedly connected to the middle of the clamping plate 2; a rotating wheel 32 is rotatably connected to the middle of the connecting plate 3; a limiting component 33 is provided in the middle of the connecting plate 3; when the elastic wire 22 contacts the plate, the clamping plate 2 will expand under the squeezing action. At this time, the connecting plate 3 and the rotating wheel 32 will move closer to the plate. During the movement of the rotating wheel 32, it will contact the elastic wire 22 and rotate. The rotating wheel 32 will flatten the surface of the elastic wire 22, reducing the bending that occurs when the elastic wire 22 contacts the plate. At the same time, the rotating wheel 32 will finally contact the plate. The limiting component 33 will restrict the rotation direction of the rotating wheel 32, so that the limiting component 33 will be in a fixed state under the limiting action. At this time, the limiting component 33 will squeeze the surface of the plate, further increasing the contact area between the device and the plate, and reducing the shaking when drilling holes in the plate.

[0028] Please see Figure 5 As shown, the limiting component 33 includes a second baffle 42; the second baffle 42 and the connecting plate 3 are rotatably connected and connected by a torsion spring; a plurality of first baffles 4 are fixedly connected to the middle of the rotating wheel 32; the surfaces of the first baffles 4 and the second baffles 42 are correspondingly arranged; when the rotating wheel 32 slides along the plate, the first baffles 4 will rotate together with the rotating wheel 32 and come into contact with the surface of the second baffles 42. When the clamping plate 2 is in a stable state, the rotating wheel 32 will stop rotating. At this time, the second baffles 42 will block the first baffles 4, reducing the situation where the rotating wheel 32 reverses with the first baffles 4, and improving the stability of the rotating wheel 32 when it squeezes the plate.

[0029] Please see Figure 4 As shown, a plurality of ball bearings 5 ​​are rotatably connected to the middle of the fixed rod 110; the ball bearings 5 ​​are arranged in an array; when the fixed rod 110 slides along the slide groove 18, the ball bearings 5 ​​will also rotate under the contact action, the ball bearings 5 ​​will reduce the friction between the fixed rod 110 and the slide groove 18, and reduce the wear caused by friction between the fixed rod 110 and the slide groove 18.

[0030] Please see Figure 2 As shown, an oil box 6 is fixedly connected to the bottom of the inner wall of the support platform 1; multiple pipes 62 are symmetrically connected in the middle of the oil box 6; the oil box 6 is located at the bottom of the slide plate 15; the oil box 6 is filled with lubricating oil, and when the slide plate 15 moves along the support platform 1, the slide plate 15 will squeeze the oil box 6, and the lubricating oil in the oil box 6 will be sprayed out from the pipes 62 under pressure and reach the surface of the screw 14, so as to realize the lubrication of the screw 14 by the device and extend the service life of the screw 14.

[0031] Please see Figure 4 As shown, the positioning block 19 has an L-shaped structure. Because the positioning block 19 has an L-shaped structure, the contact area between the positioning block 19 and the plate is larger, thus increasing the contact area between the positioning block 19 and the plate.

[0032] Working principle: The sheet material is placed on top of the support plate 17. Then, the motor 13 is started, causing the screw 14 to rotate. When the screw 14 rotates, the slide plate 15 slides along the support platform 1. At the same time, the slide plate 15 rotates the circular plate 16. When the circular plate 16 rotates, the slide groove 18 rotates, and the fixing rod 110 slides along the slide groove 18. The positioning blocks 19 slide along the support plate 17 under the transmission action of the fixing rod 110. At this time, all the positioning blocks 19 will move and move closer to the sheet material. The sheet material will be quickly fixed under the squeezing action of the positioning blocks 19. Because the positioning blocks 19 are circumferentially set, the sheet material will be positioned... Under the squeezing action, block 19 moves and is positioned at the center of support plate 17, achieving rapid positioning of support plate 17 by the device. Finally, the drilling assembly 12 can be activated to drill holes in it. Before the positioning block 19 contacts the plate, the elastic wire 22 first contacts the plate. Because the elastic wire 22 is a flexible elastic material, it deforms upon contact with the plate, causing clamping plate 2 to rotate. Subsequently, it applies elastic squeezing force to the plate, increasing the contact area between the device and the plate while reducing direct contact between the plate and positioning block 19. When the elastic wire 22 contacts the plate, clamping plate 2 expands under the squeezing action. As the connecting plate 3 and the rotating wheel 32 move closer to the plate, the rotating wheel 32 will come into contact with the elastic wire 22 and rotate during its movement. The rotating wheel 32 will flatten the surface of the elastic wire 22, reducing the bending that occurs when the elastic wire 22 comes into contact with the plate. At the same time, the rotating wheel 32 will finally come into contact with the plate, and the limiting component 33 will restrict the rotation direction of the rotating wheel 32, so that the limiting component 33 will be in a fixed state under the limiting action. At this time, the limiting component 33 will squeeze the surface of the plate, further increasing the contact area between the device and the plate. When the rotating wheel 32 slides along the plate, the first baffle 4 will rotate with the rotating wheel 32 and the second baffle 4 When the surfaces of the two plates come into contact, the rotating wheel 32 will stop rotating when the clamping plate 2 is in a stable state. At this time, the second baffle 42 will block the first baffle 4, reducing the possibility of the rotating wheel 32 rotating with the first baffle 4 in reverse. When the fixed rod 110 slides along the slide groove 18, the ball 5 will also rotate under the contact action. The ball 5 will reduce the friction between the fixed rod 110 and the slide groove 18. The oil box 6 is filled with lubricating oil. When the slide plate 15 moves along the support platform 1, the slide plate 15 will squeeze the oil box 6. The lubricating oil in the oil box 6 will be sprayed out from the pipe 62 under pressure and reach the surface of the screw 14, realizing the lubrication of the screw 14 by the device.
