Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an adjustable board clamp for wood processing. Background Technology

[0002] Timber processing, which uses timber as raw material, is mainly carried out by mechanical or chemical methods. Its products still retain the basic characteristics of timber. In the forestry industry, timber processing and forest chemical processing are both downstream industries of forest harvesting and transportation, and are important sectors for the comprehensive utilization of timber resources. In the process of timber processing, it is necessary to fix the timber, which requires the use of positioning clamps.

[0003] Existing positioning clamps are cumbersome to adjust during use, making them inconvenient to clamp wood of different widths and thicknesses and unsuitable for various processing conditions, causing inconvenience to users. Therefore, we propose an adjustable board clamp for wood processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable board clamp for wood processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable board clamp for wood processing, including a processing platform, a housing fixedly connected to the bottom of the processing platform, four round tubes rotatably connected between the inner walls of the left and right sides of the housing via bearings, a worm gear fixedly connected between two corresponding round tubes, and a worm rotatably connected between the inner walls of the front and rear sides of the housing via bearings, the worm meshing with the worm gear, and the worm being driven by a motor.

[0006] More preferably, the outer end of the circular tube extends outside the housing, the inner thread of the circular tube is connected to a screw, and the outer end of the screw is fixedly connected to a cross plate.

[0007] More preferably, the top of the processing platform is provided with four limiting holes, and the top of the horizontal plate is fixedly connected with two square rods. The top of the square rods passes through the corresponding limiting holes and is fixedly connected with a rectangular plate. The square rods are slidably connected to the inner wall of the limiting holes.

[0008] More preferably, the rectangular plate is internally threaded with hexagonal bolts, and a pressure plate is fixedly connected to the bottom end of the hexagonal bolts.

[0009] In a further preferred embodiment, a positioning rod is fixedly connected to one side of the two horizontal plates that are close to each other. The inner end of the positioning rod extends into the housing and is fixedly connected to a limit block. A spring is fixedly connected between the horizontal plate and the housing, and the spring is movably sleeved on the outside of the positioning rod.

[0010] More preferably, the bottom of the processing platform is fixedly connected to four support legs, the motor is fixedly connected to the front side of the housing, and the end of the output shaft of the motor is fixedly connected to the worm gear.

[0011] More preferably, an annular pad is fixedly connected to the top of the processing platform, and a groove is formed at the center of the annular pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the wood is placed on the top of the processing platform. The position of the square rods on both sides is adjusted according to the width of the wood. The motor drives the worm gear to rotate, which in turn drives the two meshing worm wheels to rotate. The worm wheels drive the two corresponding round tubes to rotate synchronously. The screw is screwed into the corresponding round tube, and the screw drives the horizontal plate to move towards the center. The horizontal plate drives the square rod to slide in the limiting hole. The square rods on both sides clamp and fix the wood from both sides, thus allowing for adjustment and clamping of wood of different widths. Then, the hexagonal bolt is turned downwards, causing the pressure plate to press and fix the top of the wood, making the wood and the annular pad fit tightly together. This allows for pressing and fixing of wood of different thicknesses. When drilling the wood, the groove formed in the center of the annular pad can effectively protect the drill bit, preventing it from directly contacting the processing platform and causing a collision. At the same time, the debris produced by drilling will remain in the groove, making it easier to collect the debris and preventing it from flying everywhere and being inhaled by the human body.

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 protection scope of the present utility model. Example

[0019] Please see Figure 1-4 This utility model provides a technical solution: an adjustable board clamp for wood processing, including a processing platform 1. A housing 2 is fixedly connected to the bottom of the processing platform 1. Four round tubes 3 are rotatably connected between the inner walls of the left and right sides of the housing 2 via bearings. Worm gears 5 are fixedly connected between corresponding two round tubes 3. Worms 6 are rotatably connected between the inner walls of the front and rear sides of the housing 2 via bearings. The worm 6 meshes with the worm gears 5. The worm 6 is driven by a motor 13. In use, wood is placed on top of the processing platform 1, and the positions of the square rods 9 on both sides are adjusted according to the width of the wood. The motor 13 drives the worm 6 to rotate, which in turn drives the two meshing worm gears 5 to rotate. The worm gears 5 drive the corresponding two round tubes 3 to rotate synchronously. A screw 4 is screwed into the corresponding round tube 3. Rod 4 moves the horizontal plate 7 towards the center, and the horizontal plate 7 moves the square rod 9 to slide within the limiting hole 8. The square rods 9 on both sides clamp and fix the wood from both sides, so that wood of different widths can be adjusted and clamped and fixed. Then, the hexagonal bolt 11 is turned down, and the hexagonal bolt 11 rotates downward to drive the pressure plate 12 to press and fix the top of the wood, so that the wood and the annular pad 14 fit tightly together, so that wood of different thicknesses can be pressed and fixed. When drilling the wood, the groove 19 formed in the center of the annular pad 14 can effectively protect the cutting head of the drilling tool and prevent it from directly contacting the processing platform 1 and causing a collision. At the same time, the debris produced by drilling will stay in the groove 19, making it easier to collect the debris and preventing the debris from flying everywhere and being inhaled by the human body.

[0020] In this embodiment, specifically: the outer end of the round tube 3 extends to the outside of the housing 2, the inside of the round tube 3 is threaded with a screw 4, and the outer end of the screw 4 is fixedly connected with a horizontal plate 7;

[0021] In this embodiment, specifically: the top of the processing platform 1 is provided with four limiting holes 8, and the top of the horizontal plate 7 is fixedly connected with two square rods 9. The top of the square rods 9 passes through the corresponding limiting holes 8 and is fixedly connected with a rectangular plate 10. The square rods 9 are slidably connected to the inner wall of the limiting holes 8.

[0022] In this embodiment, specifically: the rectangular plate 10 is internally threaded with a hexagonal bolt 11, and the bottom end of the hexagonal bolt 11 is fixedly connected with a pressure plate 12;

[0023] In this embodiment, specifically: a positioning rod 15 is fixedly connected to one side of the two horizontal plates 7 that are close to each other. The inner end of the positioning rod 15 extends into the housing 2 and is fixedly connected to a limit block 17. A spring 16 is fixedly connected between the horizontal plate 7 and the housing 2. The spring 16 is movably sleeved on the outside of the positioning rod 15.

[0024] In this embodiment, specifically: four support legs 18 are fixedly connected to the bottom of the processing platform 1, the motor 13 is fixedly connected to the front side of the housing 2, and the output shaft end of the motor 13 is fixedly connected to the worm gear 6;

[0025] In this embodiment, specifically: an annular pad 14 is fixedly connected to the top of the processing platform 1, and a groove 19 is formed at the center of the annular pad 14.

[0026] In operation, this invention involves placing the wood on top of the processing platform 1. The positions of the square rods 9 on both sides are adjusted according to the width of the wood. The motor 13 drives the worm gear 6 to rotate, which in turn drives the two meshing worm wheels 5 to rotate. The worm wheels 5 then drive the two corresponding round tubes 3 to rotate synchronously. The screw 4 is screwed into the corresponding round tube 3, causing the horizontal plate 7 to move towards the center. The horizontal plate 7 causes the square rods 9 to slide within the limiting holes 8. The square rods 9 on both sides clamp and fix the wood from both sides, thus allowing for adjustment and clamping of wood of different widths. Tighten the screws, then tighten the hex bolts 11. The hex bolts 11 rotate downwards, causing the pressure plate 12 to press and fix the top of the wood, so that the wood and the annular pad 14 fit tightly together. This allows for the pressing and fixing of wood of different thicknesses. When drilling the wood, the groove 19 formed in the center of the annular pad 14 can effectively protect the cutting head of the drilling tool, preventing it from directly contacting the processing platform 1 and causing a collision. At the same time, the debris produced by drilling will remain in the groove 19, making it easier to collect the debris and preventing it from flying everywhere and being inhaled by the human body.
