Description

Technical Field

[0001] This utility model relates to the field of sheet metal trimming, specifically a trimming device for office desk production and processing. Background Technology

[0002] An edge trimmer is a handheld power tool whose core function is to finely process the edges of workpieces using various high-speed rotating milling cutters. It can trim rough edges to make them smooth and perpendicular, chamfer or round corners, grooving to create mortise and tenon joints, engraving patterns, and performing contour milling with templates. It is mainly divided into fixed and mini types. When choosing, you should pay attention to power, speed, chuck compatibility, and safety design. When using it, you must wear goggles and a mask, firmly fix the workpiece, operate it with both hands steadily, feed in the direction of the reverse milling cutter's rotation, and cut to depth in stages. It is strictly forbidden to adjust the cutter while the power is on. This tool is flexible and efficient in woodworking and decoration, but safe operation is of paramount importance.

[0003] During the use of a board trimming machine, the rotating grinding disc polishes and repairs the board to meet the customer's requirements. However, different types of grinding discs are required for different types of boards, necessitating frequent disc changes and reducing worker efficiency. Therefore, the inventor urgently needs to design a device that allows for quick disc changes without removing the grinding machine, thereby improving worker efficiency and saving time and effort. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a trimming device for office desk production and processing, so as to solve the technical problem of low efficiency in changing grinding discs in traditional trimming machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trimming device for office desk production and processing, comprising a base plate, a first fixed plate fixedly connected to one side of the upper part of the base plate, two positioning rods and a first threaded rod connected inside the first fixed plate, a first movable plate fixedly connected to one end of the positioning rod, the first threaded rod and the movable plate being rotatably connected, a sliding mechanism provided inside the movable plate, the sliding mechanism including a slide rail and a slider, a first motor provided on one side of the first movable plate, a fixed frame bolted to the front of the slider, a rotating disk fixedly connected above the fixed frame via a first rotating shaft, a plurality of grinding discs fixedly connected to one side of the rotating disk via a plurality of second rotating shafts, the grinding discs being four different types of grinding discs, a second motor provided below the fixed frame, one end of the second motor being coaxial with any second rotating shaft and connected via a quick-release coupling.

[0006] By adopting the above technical solution, the stable connection between the base plate and the first fixed plate ensures the rigidity of the overall structure, providing a reliable foundation for the subsequent motion mechanism. The dual cooperation design of the positioning rod and the first threaded rod not only ensures the linear guiding accuracy of the moving plate, but also realizes the stepless adjustment function, significantly improving the workpiece positioning accuracy.

[0007] Furthermore, the rotation of the first threaded rod causes the movable plate to move back and forth, changing the front and rear positions of the movable plate, the rotating disk, and the grinding disc.

[0008] By adopting the above technical solution, the first threaded rod is manually rotated to drive the moving plate to move back and forth, giving the device the ability to manually fine adjust along the Y-axis. This mechanical transmission method has high reliability and fine adjustment accuracy, and can adjust the cutting position of the grinding disc in real time according to the plate thickness or processing depth requirements, avoiding tool wear or workpiece damage caused by power overload.

[0009] Furthermore, the first motor is a lead screw motor, and the lead screw is threadedly connected to the slider, driving the slider to slide on the slide rail and change the horizontal position of the grinding disc.

[0010] By adopting the above technical solution, the core technology to ensure processing consistency is to use a ball screw motor to drive the slider to achieve automated X-axis translation. The motor controls the slider to move at a constant speed along the slide rail, so that the grinding disc can be fed steplessly along the edge of the board, eliminating the speed fluctuation of manual operation and ensuring that the grinding depth of the entire edge line is uniform and the surface finish meets the standards.

[0011] Furthermore, one end of the second motor is connected to one end of the second rotating shaft via a quick-release coupling, and the second motor controls the grinding disc at the other end of the connected second rotating shaft to rotate.

[0012] By adopting the above technical solution, the quick-release coupling, as the core component of power transmission, creatively realizes the dynamic coupling between the motor and multiple grinding heads. Its plug-in structure allows the operator to complete the power switching in seconds without the aid of tools, completely replacing the complex process of disassembling nuts and calibrating concentricity required for traditional tool changing.

[0013] Furthermore, two second fixing plates are provided on the other side above the base plate, and a fixing block is provided on the top of each of the second fixing plates.

[0014] By adopting the above technical solution, the symmetrically arranged fixing blocks and the second fixing plate constitute the reference surface of the workpiece clamping system, providing bidirectional positioning support for the plate. The double fixing point design enhances the resistance to eccentric loads and avoids bending deformation of the thin tabletop due to single-point pressure.

[0015] Furthermore, a second threaded rod is connected inside the fixed block, and a movable block is rotatably connected to the other end of the second threaded rod. Rotating the second threaded rod causes the movable block to move up and down.

[0016] By adopting the above technical solution, the threaded lifting mechanism controls the vertical displacement of the moving block by manually rotating the second threaded rod, providing a reliable Z-axis clamping force. The self-locking characteristic of the threaded drive can completely resist grinding vibration, avoiding the risk of loosening caused by pressure fluctuations in traditional pneumatic / hydraulic clamps.

[0017] Furthermore, a collection box is provided above the base plate to collect the wood chips that fall off during sanding.

[0018] By adopting the above technical solution, the built-in collection box directly captures falling wood chips through physical interception, controlling the spread of dust from the source. Its wide-mouth design covers the entire processing area, effectively collecting the debris thrown by the rotating grinding disc and the micro-dust carried by the cyclone.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model significantly improves processing accuracy and safety through the synergistic design of a three-axis positioning structure and a stable clamping system. The combination of the positioning rod and the threaded rod ensures the forward and backward displacement accuracy of the moving plate in the Y-axis direction, eliminating the jitter error of manual feed; the slider system driven by the screw motor realizes uniform translation in the X-axis, ensuring the consistency of the processing depth of the entire edge; the lifting block and the fixed block controlled by the second threaded rod form a self-locking fixture, which effectively resists grinding vibration, enabling the chamfering, straightening and other processes of the plate edge to achieve industrial-grade flatness;

[0021] 2. This utility model breaks through the bottleneck of traditional tool changing efficiency by combining a rotary multi-grinding head with a quick-release coupling. Four commonly used grinding discs are integrated into the rotary disc, and the working position can be switched by manual rotation. The quick-release coupling enables the motor power to be switched in a short time, eliminating the time-consuming operations such as traditional tool disassembly and tool calibration. A single machine can continuously complete multiple processes, improving the production capacity of batch processing scenarios such as office desk panels. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A trimming device for the production and processing of office desks, such as Figure 1-4 As shown, the system includes a base plate 1. A first fixed plate 2 is fixedly connected to one side of the upper part of the base plate 1. The first fixed plate 2 has two positioning rods 3 and a first threaded rod 4 connected internally. One end of the positioning rod 3 is fixedly connected to a first movable plate 5. The first threaded rod 4 and the movable plate 5 are rotatably connected. A sliding mechanism 6 is provided inside the movable plate 5. The sliding mechanism 6 includes a slide rail 601 and a slider 602. A first motor 7 is provided on one side of the first movable plate 5. A fixed frame 8 is bolted to the front of the slider 602. A rotating disk 11 is fixedly connected to the top of the fixed frame 8 through a first rotating shaft 10. Several grinding discs 13 are fixedly connected to one side of the rotating disk 11 through several second rotating shafts 12. The grinding discs 13 are of four different types. The grinding disc and the fixed frame 8 are equipped with a second motor 9. One end of the second motor 9 can be designed to be coaxial with any second rotating shaft 12 and is connected by transmission through a quick-release coupling 14. The stable connection between the base plate 1 and the first fixed plate 2 ensures the rigidity of the overall structure and provides a reliable foundation for the subsequent motion mechanism. The dual cooperation design of the positioning rod 3 and the first threaded rod 4 not only ensures the linear guiding accuracy of the moving plate 5, but also realizes the stepless adjustment function, which significantly improves the workpiece positioning accuracy. At the same time, the integrated multi-grinding head system centrally deploys four types of grinding discs 13 through the rotating disk 11. With the quick switching capability of the quick-release coupling 14, it completely solves the pain points of long tool changing time and frequent process interruption in traditional equipment.

[0030] See Figure 1 , Figure 2 , Figure 3The rotation of the first threaded rod 4 drives the moving plate 5 to move back and forth, changing the front and back positions of the moving plate 5, the rotating disk 11, and the grinding disc 13. Manually rotating the first threaded rod 4 drives the moving plate 5 to move back and forth, giving the device the ability to manually fine adjust along the Y-axis. This mechanical transmission method has high reliability and fine adjustment accuracy. The cutting position of the grinding disc 13 can be adjusted in real time according to the thickness of the plate or the processing depth requirements, avoiding tool wear or workpiece damage caused by power overload. At the same time, the controllability of the front and back movement range provides sufficient safety space for operation: it is convenient for workpiece clamping when returning to the original position, and it accurately matches the processing starting point when moving forward. Its coordination with the X / Y axis movement enables the device to handle continuous grinding of straight edges, and can also deal with irregular contours through segmented adjustment, significantly expanding the process adaptability of the equipment and solving the problem that fixed trimming machines cannot flexibly adapt to various workpieces.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first motor 7 is a lead screw motor, and the lead screw is threadedly connected to the slider 602, driving the slider 602 to slide on the slide rail 601, changing the horizontal position of the grinding disc 13. The use of a lead screw motor to drive the slider 602 to achieve automated X-axis translation is the core technology to ensure processing consistency. The motor controls the slider to move at a uniform speed along the slide rail 601, so that the grinding disc 13 can be fed steplessly along the edge of the board, eliminating the speed fluctuation of manual operation, ensuring uniform grinding depth and surface finish along the entire edge. At the same time, this design, in conjunction with the multi-grinding head system, solves the problem of needing to realign after tool change in traditional processes: when the grinding disc is switched, the system can still automatically complete the precise tool movement along the preset trajectory, greatly reducing the error of repeated positioning.

[0032] See Figure 1 , Figure 2 , Figure 3 One end of the second motor 9 is connected to one end of the second rotating shaft 12 via a quick-release coupling 14. The second motor 9 controls the grinding disc 13 at the other end of the connected second rotating shaft 12 to rotate. As the core component of power transmission, the quick-release coupling 14 creatively realizes the dynamic coupling between the motor and the multi-grinding head. Its plug-in structure allows the operator to complete the power switching in seconds without the aid of tools, completely replacing the complex process of disassembling nuts and calibrating concentricity required for traditional tool changing. At the same time, this design ensures transmission rigidity and stability: the high torque transmission capability of the coupling in the connected state ensures no vibration or deviation during high-speed grinding; in the disconnected state, the rotating disk 11 is allowed to rotate freely to select the tool, avoiding motor load interference.

[0033] See Figure 1 , Figure 2 , Figure 3Two second fixing plates 15 are provided on the other side above the base plate 1. Each second fixing plate 15 is provided with a fixing block 16. The symmetrically arranged fixing blocks 16 and the second fixing plates 15 constitute the reference surface of the workpiece clamping system, providing bidirectional positioning support for the plate. The double fixing point design enhances the resistance to eccentric loads and avoids bending deformation of the thin tabletop due to single-point pressure. At the same time, the matching of the height of the fixing blocks with the horizontality of the grinding station allows the edge of the plate to naturally extend to the processing area, eliminating redundant operations of secondary position adjustment after clamping. Its integrated installation with the base plate 1 further enhances the structural stability and ensures zero displacement of the workpiece during grinding.

[0034] See Figure 1 , Figure 2 , Figure 3 The fixed block 16 is connected to a second threaded rod 17, and the other end of the second threaded rod 17 is rotatably connected to a moving block 18. Rotating the second threaded rod 17 causes the moving block 18 to move up and down. The threaded lifting mechanism controls the vertical displacement of the moving block 18 by manually rotating the second threaded rod 17, providing a reliable Z-axis clamping force. The self-locking characteristic of the threaded drive can completely resist grinding vibration, avoiding the risk of loosening caused by pressure fluctuations in traditional pneumatic / hydraulic clamps. At the same time, the lifting stroke covers the thickness range from ultra-thin decorative panels to thickened tabletops, ensuring that all kinds of workpieces can obtain a balanced vertical pressure distribution. Its cooperation with the fixed block 16 forms an adaptive clamping system: when moving upward, it clamps the workpiece, and when moving downward, it completely releases space, which facilitates the quick insertion and removal of the sheet metal.

[0035] See Figure 1 , Figure 2 , Figure 3 A collection box 19 is installed above the base plate 1 to collect sawdust falling from the sanding process. The built-in collection box 19 directly captures the falling sawdust through physical interception, controlling the spread of dust at the source. Its wide-mouth design covers the entire processing area, effectively collecting the debris thrown by the rotating sanding disc 13 and the fine dust carried by the cyclone. At the same time, the detachable box structure simplifies the cleaning process: the operator can pull it out and empty it separately without interrupting the operation of the equipment, avoiding the site restrictions and airflow reduction problems caused by traditional external pipelines. This closed collection solution not only improves the hygiene of the workshop environment, but also reduces the risk of flammable sawdust accumulation and meets the safety production standards.

[0036] The implementation principle of this embodiment is as follows: Before clamping the plate, the moving plate 5 is moved to be close to the first fixed plate 2 by rotating the first threaded rod 4, and then the moving block 18 is moved to be close to the base plate 1 by rotating the second threaded rod 17. The plate to be repaired is placed between the fixed block 16 and the moving block 18. The moving block 18 is moved by rotating the second threaded rod 17, and the fixed block 16 and the moving block 18 clamp the plate. Then the first threaded rod 4 is rotated to move the moving plate 5 forward, which further drives the grinding disc 13 forward to a suitable position. A quick-release mechanism is installed between the second motor 9 and the second rotating shaft 12 connected to the bottommost grinding disc 13. The coupling 14 and the second motor 9 drive the sanding disc 13 to rotate and repair the edge of the board. The first motor 7 controls the slider 602 to slide on the slide rail 601, which further drives the sanding disc 13 to move laterally and repair an entire edge of the board. The four sanding discs 13 are of different models and different processes need to be completed. When the second motor 9 is paused, the quick-release coupling 14 is removed and the rotating disk 11 is rotated to rotate the required sanding disc 13 to the bottom. The quick-release coupling 14 is installed and the second motor 9 is restarted to repair the board, which can achieve different process requirements. The collection box 19 below will collect the fallen wood chips, etc.
