TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling, in particular to a five-star foot reaming device. BACKGROUND

[0002] The detachable foot assembly is a furniture part convenient to disassemble and assemble, which is mainly used for the support structure of furniture such as chairs. The detachable foot assembly is usually composed of a five-star foot and a plurality of detachable feet in the shape of tubes and penetrating through front and back. The five-star foot includes a cylindrical fixing sleeve and a plurality of hollow tubular mounting feet. The detachable foot sleeve is arranged on the other end of the mounting foot and is detachably fixedly connected with the mounting foot. This structure makes the detachable foot have the advantages of convenient disassembly and assembly and facilitating transportation. The five-star foot is provided with a central hole, which needs to be connected with furniture such as chairs, and a high assembly size precision needs to be ensured.

[0003] At present, the common five-star foot central hole machining is generally rough machining after the water gap is cut off by manual operation. The size of the five-star foot central hole is basically ensured by the injection molding process. However, the product needs to be cooled after the five-star foot is injection molded due to high temperature, and the size of the five-star foot central hole will change during the cooling process, which has the problem of poor consistency. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a five-star foot reaming device, which can automatically ream the five-star foot, has high machining efficiency and good product consistency.

[0005] The present application provides a five-star foot reaming device for machining the central hole of the five-star foot, which comprises a machining table, a clamp in transverse sliding connection with the machining table, a cutting mechanism arranged on the machining table, the cutting mechanism comprising a longitudinal sliding reamer and a driving assembly driving the reamer to move close to or away from the machining table, the clamp sliding between a taking and placing position and a machining position, and the center of the clamp being located on the moving path of the reamer when the clamp is located at the machining position.

[0006] By adopting the technical scheme of the present application, the reamer can be accurately aligned with the central hole of the five-star foot for machining through the precise sliding connection and positioning mechanism, thereby improving the machining precision and the consistency of the product. The transverse sliding of the clamp enables the five-star foot to be quickly and conveniently taken and placed, reduces the time for manual operation, and improves the production efficiency. The five-star foot reaming device of the present application realizes efficient and accurate machining of the central hole of the five-star foot through the precise sliding connection and positioning mechanism, thereby improving the production efficiency and operation convenience.

[0007] In some embodiments, the cutting mechanism further comprises a sliding rail fixedly connected with the machining table, a sliding seat in sliding connection with the sliding rail, the driving assembly is arranged on the sliding seat or the sliding rail, and the reamer is in rotational connection with the sliding seat.

[0008] By adopting the technical solution of the present application, the sliding connection between the slide rail and the slide seat provides a stable and smooth moving platform for the cutting mechanism, reducing vibration and shaking during the processing process, improving processing stability, flexibility and precision, and also optimizing the maintenance and maintenance performance of the equipment.

[0009] In some embodiments, the driving assembly includes a first driving member, which drives the slide to slide along the longitudinal direction through a first transmission member.

[0010] In some embodiments, a second transmission member is further included, and the first driving member is connected to the reamer through the second transmission member.

[0011] In some embodiments, a second driving member is further included, wherein the second driving member is connected to the reamer to drive the reamer to rotate.

[0012] By adopting this technical solution, during the machining process, the first and second drive members work together to ensure precise coordination between the movement of the slide and the rotation of the reamer, achieving accurate reaming of the center hole of the five-star foot. This combination of the first and second drive members allows for convenient adjustment of the slide's movement speed and the reamer's rotation speed to accommodate the machining needs of five-star feet of varying sizes and specifications.

[0013] In some embodiments, the first driving member is fixed on the slide rail, a screw rod is rotated on the slide rail, a driving end of the first driving member is connected to the screw rod to drive the screw rod to rotate, and the slide seat is threadedly connected to the screw rod.

[0014] With this technical solution, the driving end of the first drive element (e.g., the output shaft) is connected to the screw via a connection device (e.g., a coupling, pulley, etc.). When the first drive element is activated, its power is transmitted to the screw, driving its rotation. Through a precise threaded connection and closed-loop control system, the position of the slide can be precisely controlled, thereby improving machining accuracy and stability. By adjusting the direction and speed of the screw's rotation, the direction and speed of the slide can be easily adjusted to accommodate the processing needs of five-star feet of varying sizes and specifications.

[0015] In some embodiments, the slide is connected to a pressure plate, and the pressure plate is elastically connected to the slide.

[0016] In some embodiments, the pressure plate is provided with a through hole, and the reamer cuts the five-star foot after passing through the through hole when sliding longitudinally close to the processing table.

[0017] With this technical solution, the pressure plate is connected to the slide via an elastic device (such as a spring or elastic sheet), ensuring a certain level of elastic pressure during machining, thereby firmly clamping the five-star foot. The pressure plate is provided with a through-hole that matches the diameter of the reamer. When the reamer slides longitudinally toward the machining table, it accurately passes through the through-hole and cuts the five-star foot. This precise elastic connection and through-hole design ensures accurate positioning and secure clamping of the reamer during machining, thereby improving machining accuracy and stability.

[0018] In some embodiments, the clamp is provided with a plurality of positioning posts distributed circumferentially along the center of the clamp, and positioning spaces are provided between the positioning posts.

[0019] By adopting the above technical solution, the design of the positioning space allows the five-star foot to be positioned quickly and accurately in the fixture, while also helping to prevent the five-star foot from moving or offsetting during the processing process.

[0020] In some embodiments, the clamp includes a chassis and a turntable, the chassis is provided with a plurality of straight grooves extending radially along the center of the clamp, the turntable is provided with a plurality of arc grooves corresponding to the straight grooves, and the positioning column is slidably connected to the straight grooves and the arc grooves.

[0021] By rotating the dial to adjust the position of the locating column in the straight and curved slots, different positioning requirements for the five-star foot can be achieved. This design allows the fixture to adapt to a wider range of five-star foot shapes and sizes.

[0022] In summary, this application has at least one of the following beneficial technical effects:

[0023] 1. It realizes efficient and precise processing of the center hole of the five-star foot, improving production efficiency and operation convenience.

[0024] 2. Through the cooperation of relevant institutions, we can adapt to the processing needs of five-star feet of different sizes and specifications. BRIEF DESCRIPTION OF THE DRAWINGS

The drive assembly in this embodiment includes a motor 11 and a gear mechanism 13 connected to the motor 11.

[0039] See also Figure 1 and Figure 2 The fixture 2 is in the pick-and-place position. When the fixture 2 is in the processing position, the center of the fixture 2 is located in the moving path of the reamer 17, that is, the fixture 2 is directly below the reamer 17. The fixture 2 slides between the pick-and-place position and the processing position, achieving the effect of improving the processing accuracy of the center hole of the five-star foot and the efficiency of pick-and-place, solving the problems of low processing accuracy and insufficient automation of the center hole of the five-star foot in the prior art.

[0040] See also Figure 2 and Figure 3 The processing table 4 is made of cast iron and has good rigidity and stability. The processing table 4 is provided with a horizontal slide rail 41. The fixture 2 includes a horizontal slide seat 21 that is slidably connected to the horizontal slide rail 41. The horizontal slide seat 21 is fixedly connected to the chassis 22, and the chassis 22 is rotatably connected to the turntable 23. The turntable 23 is also provided with five positioning columns 24. These positioning columns 24 are distributed along the center circumference of the fixture 2. Positioning spaces are provided between the positioning columns 24 for placing the five-star feet to be processed.

[0041] The cutting mechanism 1 includes a longitudinal slide 14, a longitudinal slide seat 12, a reamer 17, a motor 11 and a gear mechanism 13. The longitudinal slide 14 is fixedly connected to the processing table 4, and the longitudinal slide seat 12 is slidingly connected to the longitudinal slide 14 and can slide freely on the slide. The drive assembly includes a motor 11, and the motor 11 drives the slide seat to slide longitudinally through a transmission mechanism. In this embodiment, the motor 11 is a servo motor 11, and the transmission mechanism is a screw and nut pair, and can also be a synchronous pulley and synchronous belt. The reamer 17 is rotationally connected to the longitudinal slide seat 12, and rotation can be achieved through bearings. In addition, a second transmission mechanism is provided, and the motor 11 is transmission-connected to the reamer 17 through the second transmission mechanism, so that the reamer 17 rotates while the slide seat moves. In this embodiment, the second driving member is a gear mechanism 13, and the motor 11 is connected to the reamer 17 through the gear mechanism 13, driving the reamer 17 to rotate.

[0042] In order to improve the machining precision, the pressure plate 153 is connected to the longitudinal slide 12, and the pressure plate 153 is elastically connected to the longitudinal slide 12. The elastic connection can be achieved by using a spring 152 or an air cylinder. In this embodiment, the pressure plate 153 is connected to the longitudinal slide 12 through a bolt 151, and the spring 152 is connected between the longitudinal slide 12 and the pressure plate 153. The spring 152 is sleeved on the bolt 151 to provide a restoring force to the pressure plate 153. The pressure plate 153 is provided with a through hole 1521, and the reamer 17 slides longitudinally close to the machining table 4 and cuts the five-star foot after passing through the through hole 1521. This design can effectively reduce the error caused by vibration during machining and improve the machining precision.

[0043] Please refer to Figure 4 and Figure 5 , the bottom plate 22 of the clamp 2 is provided with a plurality of straight grooves 221, and the rotating disc 23 is provided with a plurality of arc-shaped grooves 231 corresponding to the straight grooves 221.

[0044] The implementation principle of this embodiment is to achieve accurate positioning and efficient machining of the center hole of the five-star foot by setting the horizontally sliding clamp 2 and the longitudinally sliding reamer 17. The adjustment function of the clamp 2 enables the device to adapt to five-star feet of different sizes, improving the versatility and flexibility of the equipment. The double-drive design of the drive assembly enables the reamer 17 to move longitudinally and simultaneously drive the reamer 17 to rotate during the approach to the five-star foot, thereby achieving efficient cutting. The elastic connection design of the pressure plate 153 further improves the machining precision and reduces the impact of vibration on the machining quality. Overall, the five-star foot reaming device of this embodiment has significant advantages in improving machining precision and efficiency, and can meet the high-precision requirements of mass production.

[0045] Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is that the reamer 17 is driven by a separate second motor 11 in this embodiment. The advantage is that the movements of the longitudinal slide 12 and the reamer 17 can be controlled separately.

[0047] Embodiment 3

[0048] The difference between this embodiment and the above-mentioned embodiments is that a cooling system and a chip removal system are added to further improve the machining quality and the service life of the equipment.

[0049] Specifically, the cutting mechanism 1 also includes a cooling system and a chip removal system. The cooling system includes a coolant pump, a coolant pipe, and a nozzle. The coolant pump delivers coolant to the nozzle through the coolant pipe. The nozzle is located near the reamer 17 and can spray coolant directly onto the cutting area, removing heat generated by cutting, reducing cutting temperature, and extending the service life of the reamer 17. The chip removal system includes a chip conveyor and a chip removal pipe. The chip conveyor is located below the machining table 4 and can collect chips generated during the cutting process and discharge them through the chip removal pipe, maintaining a clean working environment and preventing chips from affecting machining accuracy.

[0050] The operating principle of this embodiment is to further improve the machining conditions for the center hole of a five-star foot by adding a cooling system and a chip removal system. The introduction of the cooling system effectively reduces cutting temperature, minimizes thermal deformation, and improves machining accuracy. The addition of the chip removal system promptly removes chips generated during the cutting process, preventing chip accumulation that affects machining quality and equipment life. The synergistic effect of these two systems makes this embodiment of the five-star foot reaming device outstanding in terms of high performance and reliability, making it particularly suitable for large-scale production and high-precision applications.

[0051] Example 4

[0052] The difference between this embodiment and the above embodiment is that a multi-station design is adopted, which can process multiple five-star feet at the same time, greatly improving production efficiency.

[0053] Specifically, a plurality of fixtures 2 are provided on the processing table 4, and each fixture 2 can slide between the pick-up and placement position and the processing position. Each fixture 2 is equipped with an independent positioning column 24 and a positioning space, which can fix multiple five-star feet at the same time. The cutting mechanism 1 includes multiple reamers 17 and drive assemblies. Each reamer 17 corresponds to a fixture 2, and multiple five-star feet can be processed at the same time. The structure of each reamer 17 and the drive assembly is the same as that of the aforementioned embodiment and will not be repeated here. In addition, in order to coordinate the operation of multiple stations, a control panel is also provided. The operator can select different processing modes through the control panel to switch between single stations or multiple stations.

[0054] The operating principle of this embodiment is as follows: Through a multi-station design, the five-star foot reaming device can process multiple five-star feet simultaneously, greatly improving production efficiency. The independent operation of each fixture 2 and reamer 17 provides greater flexibility in the processing process, allowing the number of processes to be adjusted according to actual needs. The introduction of a control panel simplifies the operation process and improves the device's usability. Overall, the five-star foot reaming device of this embodiment offers significant advantages in efficient production and is particularly suitable for use in large furniture manufacturing enterprises.

[0055] Example 5

[0056] The difference between this embodiment and the above embodiments is that an automatic detection system is added to monitor the parameters during the processing in real time to ensure the processing quality.

[0057] Specifically, the cutting mechanism 1 also includes an automatic detection system, which includes sensors and a controller. The sensors are arranged around the reamer 17 and the fixture 2, and can monitor parameters such as cutting force, cutting speed, and cutting temperature in real time. The controller is connected to the sensors and can receive data transmitted by the sensors and adjust them according to the preset process parameters. For example, when the cutting force exceeds the preset value, the controller will reduce the feed speed to prevent overload damage to the equipment; when the cutting temperature is too high, the controller will increase the coolant flow rate to reduce the cutting temperature. In addition, the controller can also record data during the processing and generate reports for subsequent analysis and optimization.

[0058] The implementation principle of this embodiment is as follows: by adding an automatic detection system, real-time monitoring and intelligent control of the machining process are achieved. The precise measurement of the sensor and the intelligent adjustment of the controller make the machining process more stable and reliable, avoiding quality fluctuations caused by human factors. Data logging and report generation functions provide strong support for process optimization, helping to continuously improve machining accuracy and efficiency. In short, the five-star foot reaming device of this embodiment excels in intelligent and high-precision machining, making it particularly suitable for the needs of high-end furniture manufacturers.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, which are merely illustrative of the principles of the present invention.
