Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to an auxiliary fixing device for wood cutting. Background Technique

[0002] Wood: The lignified tissue of plants. Logs are wooden segments of a certain length cut longitudinally from a round log according to the standards or special regulations of dimensions, shapes, and quality. Generally, it is stipulated that the length of the lumber does not exceed 12m or 40 feet, and it has great uses in many aspects such as construction, furniture, craft carving, and papermaking. Wood products are used for a long time in life. When existing wood products are processed, most of them need to cut wood. The process of wood cutting is more complicated. First, the round log is cut into wooden boards, and then the wooden boards are cut to a fixed size according to the required dimensions. This cutting process requires the use of an auxiliary fixing device for wood.

[0003] Chinese Patent Network Application No. CN219359691U discloses "A Wood Fixing Device for Wood Cutting". The workbench is composed of support legs and a workboard. The workboard is fixedly installed at the top of the support legs. A cutting mechanism is installed on the upper surface of the workboard. An L-shaped plate and a blocking plate are respectively installed on the upper surface of the workboard. An electric push rod is fixedly connected to the upper surface of the L-shaped plate. The telescopic end of the electric push rod passes through the L-shaped plate and is fixedly connected to a pressing plate. An installation block is fixedly connected to the lower surface of the L-shaped plate. A first sliding opening is opened on the upper surface of the workboard. In this utility model, through the setting of the sleeve, the tension spring, and the sliding rod, the tension spring pulls the L-shaped plate towards the blocking plate through the sliding rod, so that the wooden board abuts against the blocking plate tightly, and the pressing plate is driven by the electric push rod to move downwards to fix the wooden board. After the cutting is completed and the cut wooden board is taken out, the pressing plate is lifted upwards. At this time, the L-shaped plate will push the wooden board towards the blocking plate again, thus facilitating single-person operation for cutting.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects:

[0005] For the fixing device for wood cutting, the adjustable range of its adopted fixing structure is limited, resulting in difficulty in fixing larger-sized board-shaped wood, which reduces the practicality. Therefore, it is necessary to provide an auxiliary fixing device for wood cutting to solve the above technical problems. Content of the Utility Model

A plurality of card slots 14 are formed on the opposite surfaces of the two movable seats 4, and a sliding groove 11 communicating with the card slots 14 is formed inside the movable seat 4. A slider 12 is slidably connected inside the sliding groove 11. An L-shaped plate 7 is fixedly installed on the upper surfaces of the two sliders 12 together, and installation grooves 15 are formed on the opposite surfaces of the two sliders 12. A tension spring 16 is fixedly installed inside the installation groove 15. One end of the tension spring 16 is fixedly connected to a latch 13 engaged with the card slot 14.

[0027] Further, the latch 13 is in an L-shaped structure, and the slider 12 is in an L-shaped structure.

[0028] Further, electric telescopic rods 5 are symmetrically and fixedly installed on the upper surface of the L-shaped plate 7. The output ends of the two electric telescopic rods 5 penetrate through the L-shaped plate 7 and are fixedly connected to a pressing plate 6 together. By adjusting the electric telescopic rods 5, the pressing plate 6 is controlled to press and fix the wood in the vertical direction.

[0029] During implementation, on the basis of starting the motor 19 to drive the lead screw 9 connected to its output shaft to rotate, so as to control the outer movable seat 4 to drive the L-shaped plate 7 to move, the L-shaped plate 7 and the movable seat 4 are also movably connected by means of the slider 12 and the sliding groove 11. By pulling the latch 13, the tension spring 16 is stretched, so as to control the latch 13 to disengage from the inside of the card slot 14, thereby facilitating the adjustment and fixation of the horizontal position of the L-shaped plate 7 on the movable seat 4, greatly increasing the adjustable range of the L-shaped plate 7, facilitating the fixation of larger-sized plate-shaped wood, and enhancing the practicability.

[0030] Embodiment Two:

[0031] As Figure 5 shown, on the basis of Embodiment One, the present utility model provides a technical solution: A blocking plate 10 is fixedly installed on the upper surface of the workbench surface 3, and four legs 2 are evenly and fixedly installed on the lower surface of the workbench surface 3. A toothed plate 18 is inserted into each leg 2. A footrest 17 is fixedly connected to the lower end of the toothed plate 18. Shells 1 are fixedly installed on the opposite surfaces of the left and right corresponding legs 2. A spring 21 is fixedly installed inside the shell 1. One end of the spring 21 is fixedly connected to a fastener 20 penetrating through the shell 1 and the leg 2. The fastener 20 is engaged with the toothed plate 18.

[0032] During implementation, by pulling the fastener 20, the spring 21 is stretched, and one end of the fastener 20 is disengaged from the tooth gap of the toothed plate 18, so that the toothed plate 18 can be pulled out a certain length and fixed according to requirements, achieving the effect of changing the support height of the footrest 17 at the corresponding position, facilitating stable placement on uneven ground and improving stability.

[0033] Working principle: When placing this fixing device, adjust the support height of the footrest 17 at the corresponding position according to the unevenness of the ground. First, pull the fastener 20 to stretch the spring 21, so that one end of the fastener 20 is disengaged from the tooth gap of the toothed plate 18. Then, pull out the toothed plate 18 from the inside of the leg 2 by a certain length. Finally, release the fastener 20. At this time, under the elastic pulling force of the spring 21, one end of the fastener 20 is clamped into the tooth gap of the toothed plate 18 again, fixing the toothed plate 18 and making the device placed stably. When in use, first place the plate-shaped wood on the upper surface of the workbench 3, between the blocking plate 10 and the L-shaped plate 7. Then, start the motor 19 to drive the lead screw 9 connected to its output shaft to rotate, driving the outer movable seat 4 to drive the L-shaped plate 7 to move leftward. Finally, start the electric telescopic rod 5 to drive the pressing plate 6 connected to its output end to move downward to press and fix the wood. When it is necessary to adjust the position of the L-shaped plate 7 on the movable seat 4, first pull the block 13 to stretch the tension spring 16, so that the block 13 is disengaged from the inside of the card slot 14. Then, move the L-shaped plate 7 to make the slider 12 connected to it slide inside the sliding slot 11. Finally, release the block 13. At this time, under the elastic pulling force of the tension spring 16, the block 13 is clamped into the card slot 14 at the corresponding position again, fixing the adjusted L-shaped plate 7.
