Description

Technical Field

[0001] The utility model relates to the technical field of furniture tenon processing, in particular to a fine processing device for assembled furniture tenons. Background Technique

[0002] Tenons are the main structural methods of ancient Chinese architecture, furniture and other instruments. It is a connection method that combines concave and convex parts on two components. Most ancient Chinese woodcrafts adopted tenon joints. Among them, the covered bridges did not use a single nail or rivet but adopted tenon joints. The protruding tenons on the wooden components and the recessed mortises simply bite together, combining the wooden components. Due to the different shapes of the connecting components, thousands of ever-changing combination methods are derived. Tenons can be divided into right-angle tenons, dovetail tenons, elliptical tenons, and round tenons according to their shapes.

[0003] For example, Chinese Patent CN220993960U discloses a fine processing device for assembled furniture tenons, including a processing table, support feet fixed to the bottom of the processing table. There are several groups of support feet fixed to the bottom of the processing table to support the whole device and ensure the stability of the whole device. A fixed table is fixed to the top of the processing table, and a first chute is opened on the top of the fixed table. There are four groups of first chutes opened on the top of the fixed table.

[0004] However, in the prior art, after the tenon is processed and polished, when the polishing belt is loose, it is easy to slide during operation, resulting in increased wear of the machine friction pair, thereby shortening the service life of the machine. Due to the loose belt, the transmission power of the machine is insufficient, which will cause the machine speed to decrease, affecting the work efficiency. At the same time, the loose belt will also shake during work, generating a reciprocating motion, wasting energy, and further affecting the polishing efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that when the polishing belt is loose in the prior art, it is easy to slide during operation, resulting in increased wear of the machine friction pair, and to propose a fine processing device for assembled furniture tenons.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1-4As shown in the figure, the utility model provides a fine processing device for the tenon of assembled furniture, which includes a bottom plate 1 and a processing mechanism 3 installed on the top thereof. A moving mechanism 2 is installed in the center of the top of the bottom plate 1, and a grinding mechanism 4 is installed on one side of the top of the bottom plate 1;

[0025] The grinding mechanism 4 includes a fixed block 46 and a fixed frame 49. One side of the top of the fixed frame 49 is rotatably connected with a swing rod 47. The middle of the swing rod 47 is rotatably connected with a movable wheel 471. One side of the fixed frame 49 is rotatably connected with a driving wheel 41. One end of the fixed block 46 is rotatably connected with a rotating frame 44. The top and bottom ends of the rotating frame 44 are rotatably connected with driven wheels 45. The middle of the fixed frame 49 is fixedly connected with a fixed sleeve 42. An activity rod 421 is slidably connected inside the fixed sleeve 42. One end of the activity rod 421 is fixedly connected with a limiting rod 422. A limiting hole 441 is formed on the surface of the rotating frame 44. The limiting hole 441 is slidably connected with the limiting rod 422. One side of the rotating frame 44 is rotatably connected with a guiding frame 442. One end of the limiting rod 422 is rotatably connected with the fixed block 46.

[0026] Next, the specific settings and functions of this embodiment will be described in detail. First, the raw material to be processed is placed on the top of the processing table 22. In order to ensure that the raw material does not move during the processing, it needs to be stably clamped. At this time, the worker will turn the threaded rod 25. As the threaded rod 25 rotates, it will push the clamping plate 26 connected thereto to move. The movement of the clamping plate 26 will gradually approach the raw material and finally clamp the raw material tightly on the processing table 22 to ensure its stable position for subsequent processing operations. After the raw material is stably clamped, the processing equipment will start to process the tenon. After the processing is completed, the next step is the grinding step to remove the burrs or uneven parts that may be generated during the processing. At this time, the grinding mechanism 4 starts to play a role.

[0027] When the motor 411 is started, it will drive the driving wheel 41 to rotate. The rotation of the driving wheel 41 will drive the grinding belt 43 connected thereto to start moving. At the same time, since both ends of the grinding belt 43 are respectively wound around two driven wheels 45 and a movable wheel 471, the driven wheels 45 and the movable wheel 471 will also rotate accordingly.

[0028] During the grinding process, the grinding belt 43 will grind the processed part of the tenon to remove the uneven parts. In order to obtain a better grinding effect, the position and angle of the grinding belt 43 need to be finely adjusted. At this time, the air cylinder 48 can be used to control the movement of the swing rod 47. When the air cylinder 48 pushes or pulls the swing rod 47, the swing rod 47 will rotate around the connection end with the fixed frame 49 as the center. This rotational movement will drive the position of the movable wheel 471 to change, thereby changing the position and angle of the grinding belt 43 and avoiding the grinding belt 43 from becoming slack.

[0029] During the movement of the swing rod 47, the rotating frame 44 also swings. The swing of the rotating frame 44 is achieved through the coordinated action of the guide frame 442. The guide frame 442 can ensure that the rotating frame 44 remains stable during the swing and does not shift. While the rotating frame 44 is swinging, the limit rod 422 slides inside the limit hole 441. This sliding process not only plays a guiding role but also ensures that the swing amplitude and speed of the rotating frame 44 are within a controllable range.

[0030] Embodiment 2: As Figure 2 - Figure 4 shown, one side of the fixed frame 49 is rotatably connected to a cylinder 48, the top end of the cylinder 48 is rotatably connected to the swing rod 47, one side of the fixed frame 49 is provided with a motor 411, and the output end of the motor 411 is fixedly connected to the driving wheel 41. A grinding belt 43 is sleeved on the surfaces of the driving wheel 41 and the movable wheel 471, and the grinding belt 43 is sleeved on the surfaces of two driven wheels 45. The moving mechanism 2 includes a moving member 21, a processing table 22 is installed on the top of the moving member 21, guide rail members 23 are installed on both sides of the bottom of the processing table 22, and a fixing plate 24 is fixedly connected to one side of the top of the processing table 22. A threaded rod 25 is threadedly connected to the surface of the fixing plate 24, and one end of the threaded rod 25 penetrates through the fixing plate 24. One end of the threaded rod 25 is rotatably connected to a clamping plate 26, and the bottom of the clamping plate 26 is slidably connected to the processing table 22. The processing mechanism 3 includes a first electric platform 31, a second electric platform 32 is installed on one side of the first electric platform 31, and a milling cutter 33 is fixedly connected to one side of the second electric platform 32.

[0031] The effect achieved by the entire embodiment is that the movement of the processing table 22 is driven by the moving member 21. The design of the moving member 21 fully considers the stability and flexibility during the processing, and can accurately control the moving direction and distance of the processing table 22 according to different processing requirements. In this way, the worker can conveniently control the processing position of the tenon and achieve precise positioning.

[0032] During the movement of the processing table 22, the guide rail members 23 play a key guiding role. The guide rail members 23 are made of high-strength and high-precision materials, and through precision machining and assembly, they can ensure that the processing table 22 remains stable during movement. At the same time, the first electric platform 31 and the second electric platform 32 are also equipped. The first electric platform 31 is responsible for controlling the horizontal position of the second electric platform 32, thereby achieving precise control of the horizontal position of the milling cutter 33. The second electric platform 32 controls the height of the milling cutter 33 through its own movement. This design enables the milling cutter 33 to move vertically downward stably during processing, ensuring the precise processing of the tenon.

[0033] In practical applications, the motion parameters of the processing table 22 and the milling cutter 33 can be flexibly adjusted according to different processing requirements. For example, when processing tenons of different sizes, only by adjusting the motion parameters of the moving member 21 and the electric platform through the control system, rapid and accurate positioning and adjustment can be achieved. This not only improves the processing efficiency but also reduces the operation difficulty and cost.

[0034] The usage method and working principle of this device: When processing tenons, first, the raw material needs to be placed on the top of the processing table 22. Then, by turning the threaded rod 25, the threaded rod 25 will push the clamping plate 26 to move, thereby accurately positioning and clamping the raw material.

[0035] During the processing, the function of the moving member 21 is to control the movement of the processing table 22, which enables us to conveniently control the processing position of the tenon. At the same time, the guide rail member 23 plays a key guiding role to ensure that the processing table 22 remains stable during movement, thereby improving the processing accuracy and efficiency.

[0036] In addition, the first electric platform 31 is responsible for controlling the horizontal position of the second electric platform 32, thereby achieving precise control of the horizontal position of the milling cutter 33. The movement of the second electric platform 32 can not only control the horizontal position of the milling cutter 33 but also control its height. This design enables the milling cutter 33 to move vertically downward stably during processing and precisely process the tenon.

[0037] After the processing is completed, the grinding mechanism 4 is used for grinding. The motor 411 drives the driving wheel 41 to rotate, and then drives the grinding belt 43 to start moving. At the same time, the two driven wheels 45 and a movable wheel 471 will also rotate accordingly to ensure that the grinding belt 43 can evenly grind the processed part.

[0038] Through the control of the air cylinder 48, the swing rod 47 will rotate with the connection end to the fixed frame 49 as the center. This rotational movement will control the position of the movable wheel 471, thereby adjusting the angle and position of the grinding belt 43. During the control process, the guide frame 442 plays a synergistic role to ensure that the rotating frame 44 can swing smoothly. At the same time, the limit rod 422 slides inside the limit hole 441, playing a guiding and limiting role to ensure the stability and safety of the entire grinding process.

[0039] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
