Description

Technical Field

[0001] This utility model belongs to the field of furniture production technology, specifically relating to a wood cutting device for bedside table production. Background Technology

[0002] In the furniture manufacturing industry, bedside tables are an important component of bedroom furniture. Their production involves multiple processes, and wood cutting is the fundamental step in the entire production process. The accuracy of wood cutting directly affects the efficiency of subsequent assembly processes and the quality of the finished bedside table. Currently, the wood cutting equipment commonly used in bedside table production is mainly divided into two categories: semi-automatic wood cutting machines and manual table saws.

[0003] Manual sliding table saws are widely used cutting equipment in small and medium-sized enterprises due to their relatively simple structure and low purchase cost. However, existing manual sliding table saws have the following problems during use:

[0004] First, the positioning mechanism lacks precision. The positioning guide of a traditional manual sliding table saw is usually fixed directly to the worktable with bolts. When adjusting, the bolts must be loosened first, the guide must be manually pushed to the approximate position, and then the bolts must be tightened. Due to the lack of precise guiding and positioning components, the guide is prone to offset during movement, resulting in a positioning error of 2-3mm. However, the dimensional tolerance requirements for components such as the side panel and top panel of the bedside table are generally within 0.5mm. The traditional positioning method cannot meet the precision requirements.

[0005] Second, the adjustment of the ruler on traditional equipment is inconvenient. One person needs to hold the ruler steady while another person uses a ruler to adjust it, making the process cumbersome. In addition, bedside table production often requires changing the cutting size according to different models, and the frequent adjustments further reduce production efficiency. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a wood cutting device for bedside table production, which solves the problems of insufficient positioning accuracy, poor stability, and inconvenient operation of existing manual sliding table saws.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a wood cutting device for bedside table production, comprising a frame, a worktable fixedly mounted on the top of the frame, a drive assembly and a self-locking adjustment mechanism installed in the frame, a saw blade driven by the drive assembly, the upper side of the saw blade passing through a through groove on the worktable, a positioning seat slidably mounted on the top surface of the worktable on one side of the saw blade, a scale etched on the worktable surface between the positioning seat and the saw blade, and a rack and pinion mechanism comprising a rack and pinion mechanism, one end of the rack and pinion mechanism connected to the positioning seat, the rack and pinion mechanism meshing with a gear, the gear and worm gear being coaxially mounted, the worm gear and worm gear meshing with a worm, the shafts of the worm and worm gear being rotatably mounted on a second support seat and a second bearing seat, respectively, the second support seat and the second bearing seat being fixedly mounted on the frame.

[0008] The beneficial effects of this utility model are as follows: the positioning seat is moved stably by the self-locking adjustment mechanism, and positioned in the required position according to the worktable surface. The self-locking characteristic provides stable support for one side of the wood, so that the wood can be processed into the required size by the saw blade.

[0009] To ensure the stability of the positioning seat's movement;

[0010] As a further improvement to the above technical solution: the positioning seat includes an angle iron, one end of which is connected to a guide rod, and a linear bearing is slidably mounted on the outer side of the guide rod. The linear bearing is fixed on a support seat, which is fixed on the frame.

[0011] The beneficial effects of this improvement are: the guide rod, in conjunction with the linear bearing, plays a guiding and supporting role, ensuring the stability of the positioning seat's movement on the worktable.

[0012] To prevent the guide rod from coming off the linear bearing;

[0013] As a further improvement to the above technical solution: the other end of the guide rod is connected to a limiting plate.

[0014] The beneficial effect of this improvement is that the limiting plate acts as a limit, preventing the guide rod from coming out of the linear bearing.

[0015] To prevent wood chips generated during wood cutting from affecting the meshing of the gear mechanism in the self-locking adjustment mechanism;

[0016] As a further improvement to the above technical solution: a cover plate is connected to one side wing plate of the angle iron, the cover plate is installed on the top of the self-locking adjustment mechanism, the cover plate is a channel steel structure, and the two side flanges of the cover plate are located on the left and right sides of the angle iron and connected to the two ends of the angle iron.

[0017] The beneficial effects of this improvement are: the cover plate acts as a shield, preventing wood chips generated during the cutting process from falling and adhering to the self-locking adjustment mechanism.

[0018] To further reduce the risk of sawdust coming into contact with the self-locking adjustment mechanism;

[0019] As a further improvement to the above technical solution: the bottom end of the other flange of the angle iron and the bottom end of the flange of the cover plate are both slidably connected to the top surface of the workbench.

[0020] The beneficial effects of this improvement are: during the movement of the angle iron and cover plate, the sawdust accumulated on the workbench can be pushed away, preventing it from entering under the cover plate.

[0021] To reduce effort in rotating the worm gear;

[0022] As a further improvement to the above technical solution: a handwheel is connected to one end of the worm gear.

[0023] The beneficial effect of this improvement is that the operator can drive the worm gear to rotate with the handwheel in a labor-saving manner.

[0024] To ensure stable rotation of the saw blade through the use of drive components;

[0025] As a further improvement to the above technical solution: the drive assembly includes a motor, the motor is connected to the drive shaft through a belt drive mechanism, the drive shaft is rotatably mounted in a bearing housing, the motor and the bearing housing are fixed on the frame, and the saw blade is fixed at one end of the drive shaft.

[0026] The beneficial effects of this improvement are: the motor can drive the saw blade to rotate stably and at high speed through the belt drive mechanism, thus enabling efficient cutting of wood.

[0027] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 3: A wood cutting device for bedside table production includes a frame 1. A worktable 4 is fixedly mounted on the top of the frame 1. A drive assembly 2 and a self-locking adjustment mechanism 7 are installed in the frame 1. The drive assembly 2 drives a saw blade 3. The upper side of the saw blade 3 passes through a through groove in the worktable 4. A positioning seat 6 is slidably mounted on the top surface of the worktable 4 on one side of the saw blade 3. A scale 5 is etched on the worktable 4 between the positioning seat 6 and the saw blade 3. The self-locking adjustment mechanism 7 includes a rack 71. One end of the rack 71 is connected to the positioning seat 6. The rack 71 meshes with a gear 72. The gear 72 is coaxially mounted with a worm gear 74. The worm gear 74 meshes with a worm wheel 74. The worm gear 75 and worm wheel 74 are rotatably mounted on support seat 2 76 and bearing seat 2 73, respectively. Support seat 2 76 and bearing seat 2 73 are fixed on the frame 1. The positioning seat 6 is driven to move stably by the self-locking adjustment mechanism 7, and is positioned to the required position according to the worktable 4. The self-locking characteristic provides stable support for one side of the wood, so that the wood can be processed into the required size by the saw blade 3. The positioning seat 6 includes an angle iron 61, which is connected to one end of the guide rod 63. A linear bearing 64 is slidably mounted on the outside of the guide rod 63. The linear bearing 64 is fixed on support seat 1 65, which is fixed on the frame 1. The guide rod 63 cooperates with the linear bearing 64. The guide rod 63 serves as a guide and support, ensuring the stability of the positioning seat 6 as it moves on the worktable 4. The other end of the guide rod 63 is connected to a limiting plate 66, which limits the movement of the guide rod 63 and prevents it from dislodging from the linear bearing 64. A cover plate 62 is connected to one side of the angle iron 61, covering the self-locking adjustment mechanism 7. The cover plate 62 is a channel steel structure, with its two side flanges located on the left and right sides of the angle iron 61 and connected to both ends of the angle iron 61. The cover plate 62 serves to cover and prevent wood chips generated during cutting from falling onto the self-locking adjustment mechanism 7. The bottom end of the other side flange of the angle iron 61 and the bottom end of the cover plate 62 are slidably connected. The top surface of the workbench 4 is connected to the angle iron 61 and the cover plate 62. During the movement, the sawdust accumulated on the workbench 4 can be pushed away to prevent it from entering under the cover plate 62. One end of the worm gear 75 is connected to a handwheel 77. The operator can drive the worm gear 75 to rotate with ease by using the handwheel 77. The drive assembly 2 includes a motor 20. The motor 20 is connected to the drive shaft 22 through a belt transmission mechanism 21. The drive shaft 22 is rotatably mounted in the bearing seat 23. The motor 20 and the bearing seat 23 are fixed on the frame 1. The saw blade 3 is fixed to one end of the drive shaft 22. The motor 20 can drive the saw blade 3 to rotate stably and at high speed through the belt transmission mechanism 21 to perform efficient cutting of wood.

[0035] The working principle of this technical solution is as follows: The position of the positioning seat 6 is adjusted according to the size requirements of the headboard component to be processed. The operator holds the handwheel 77 and rotates it clockwise or counterclockwise. The handwheel 77 drives the worm gear 75 to rotate. The worm gear 75 meshes with the worm wheel 74 for transmission. Since the worm wheel 74 and the gear 72 are coaxially installed, the gear 72 rotates synchronously with the worm wheel 74, thereby driving the rack 71 to move horizontally. The rack 71 drives the positioning seat 6 to slide along the worktable surface 4. During the adjustment process, the distance between the inner side of the angle iron 61 of the positioning seat 6 and the saw blade 3 is observed by referring to the scale 5 on the worktable surface 4. When the distance reaches the required size, the handwheel 77 is stopped. Since the meshing of the worm gear 75 and the worm wheel 74 has a self-locking characteristic, the positioning seat 6 will be stably fixed in the current position without the need for additional locking operation.

[0036] Place the wood to be cut, such as the side panel of a bedside table, on the workbench 4 using solid wood boards, so that one edge of the wood is in contact with the inner wing plate of the angle iron 61 of the positioning seat 6, and the top surface of the wood is in contact with the upper wing plate of the angle iron 61, ensuring that the wood will not shift up or down or left or right during the pushing process. Start the motor 20 of the drive assembly 2. The motor 20 drives the drive shaft 22 to rotate through the belt transmission mechanism 21. The saw blade 3 at the end of the drive shaft 22 rotates at high speed. After the saw blade 3 rotates stably, the operator holds the end of the wood away from the saw blade 3 with both hands and pushes the wood at a uniform speed along the workbench 4 towards the saw blade 3, ensuring that the wood is always in contact with the positioning seat 6.
