DETAILED DESCRIPTION

[0021] The embodiments described below are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See Figure 1 The present embodiment provides a key chain automatic processing and polishing machine, including a key chain automatic processing and polishing machine frame and a control console, wherein the key chain automatic processing and polishing machine frame is provided with a bottom plate 1, and the key chain automatic processing and polishing machine frame is provided with a vibration feeding tray 2 with key chains installed, a discharge guide rail 4 connected to the vibration feeding tray 2 at one end, a linear vibrator 5 arranged at the bottom of the discharge guide rail 4, a first feeding track 6, a first feeding device 7, a first polishing device 8, a transfer mechanism 9, a second feeding track 10, a second feeding device 11, and a second feeding device 12 in sequence according to the processing order of the key chains. The vibrating feed tray 2 is provided with a lifting device 3 at the bottom, the discharge guide rail 4, the first feed track 6 and the second feed track 10 are all linear transport tracks matching the key chain, the first feed device 7, the transfer mechanism 9, the second feed device 11 and the second polishing device 12 are all combined mechanisms composed of multiple parts; the first polishing device 8 is the two circular polishing wheels arranged opposite to each other, and the third polishing device 13 is a circular polishing wheel arranged on one side of the second feed track 10.

[0023] In this embodiment, the key chains that need to be polished are arranged in an orderly manner by being put into the vibrating feed tray 2. The vibrating feed tray 2 includes a cylindrical hopper, a fixed frame provided at the lower end of the cylindrical hopper, a spirally ascending track provided on the inner wall of the cylindrical hopper, a vibrating electromagnet provided in the center of the bottom of the cylindrical hopper, a swing spring provided inside the fixed frame below the cylindrical hopper, and a shock-absorbing rubber pad provided at the bottom end of the fixed frame. A lifting device 3 is also provided at the bottom of the vibrating feed tray 2. After the key chains enter the vibrating feed tray 2, the cylindrical hopper gradually moves to the root of the spirally ascending track on the inner wall of the cylindrical hopper under the action of the vibrating electromagnet and the swing spring, and then rises along the spirally ascending track on the inner wall of the cylindrical hopper. Due to the action of the vibration force and the swing force, the key chains gradually change their posture during the rising process, and can then enter the discharge guide rail 4 in an orderly arranged posture. The linear vibrator 5 is provided at the bottom of the discharge guide rail 4. The linear vibrator 5 provides an exciting force to the discharge guide rail 4 to make the key chain move forward linearly and enter the first feeding track 6. Then the key chain moves to the first polishing device 8 through the first feeding device 7 to polish the outer parting line. A first fixed plate 14 is provided in the first feeding device 7, and two slide rails 15 parallel to each other are provided on the first fixed plate 14, and two freely movable sliders 16 are provided on the slide rail 15, and a cylinder 18 is installed on the slider 16, and the cylinder 18 is fixed to the slider 16 through a cylinder fixing seat 17. There is also a protrusion 19 on the driving end of the cylinder 18, and the protrusion 19 is connected to a second fixed plate 20. The first feeding device 7 is provided with a first clamping mechanism 21 on the second fixed plate. The first feeding device 7 is powered by a motor external to the slide rail 15 to drive the slider 16 to drive the entire first feeding device 7 to slide left and right, and the lifting of the second fixed plate 20 is controlled by the cylinder 18, thereby driving the first clamping mechanism 21, clamping the keyhole to move on the first feeding track 6, and moving the key chain to the first polishing device 8, and using the two circular polishing wheels oppositely arranged in the first polishing device 8 to polish the outer mold line. Then, the key chain enters the transfer mechanism 9, which includes a rotating block 33 and a pushing cylinder 35. The rotating block 33 is connected to a card slot 34, and the driving end of the pushing cylinder 35 is connected to a top block 36. The key chain enters the transfer mechanism 9 from the first feeding track 6, and will first reach the card slot 34 facing the first feeding track 6. The rotating block 33 drives the card slot 34 to rotate, so that the card slot 34 faces the second feeding track 10. Then the pushing cylinder 35 pushes the top block 36 to push the key chain from the card slot 34 into the second feeding track 10, thereby realizing the transfer of the key chain.Furthermore, a first fixed plate 14 is provided in the second feeding device 11, and two mutually parallel slide rails 15 are provided on the first fixed plate 14, and two freely movable sliders 16 are provided on the slide rails 15, and a cylinder 18 is installed on the slider 16, and the cylinder 18 is fixed to the slider 16 through a cylinder fixing seat 17. There is also a protrusion 19 on the driving end of the cylinder 18, and the protrusion 19 is connected to a second fixed plate 20. The second feeding device 11 is provided with a second clamping mechanism 22 on the second fixed plate 20. The second feeding device 11 is powered by a motor externally connected to the slide rail 15 to drive the driving slider 15 to drive the entire second feeding device 11 to slide left and right, and the lifting of the second fixed plate 20 is controlled by the cylinder 18, thereby driving the second clamping mechanism 22, clamping the keyhole and moving it on the second feeding track 10, and moving the key chain to the second polishing device 12 and the third polishing device 13 for polishing. The second polishing device 12 includes a radial slide 23 and a first slider 24 that matches the radial slide 23. The first slider 24 is provided with a support seat 25 on top. The support seat 25 is provided with a transverse slide 26 and a second slider 27 that matches the transverse slide 26. The second slider 27 is provided with a support frame 28 on top. A lifting slide 29 is provided on one side of the support frame 28. A third slider 30 that matches the lifting slide 29 is connected to the third slider 30. The third slider 30 is connected to a spindle motor 31. The radial slide 32, the transverse slide 26, and the lifting slide 29 are all connected to a drive cylinder 32. The drive cylinder 32 can control the movement of the radial slide 23, the transverse slide 26, and the lifting slide 29, thereby adjusting the position of the spindle motor 31. The spindle motor 31 is equipped with a milling cutter that is clamped by a chuck. The high-speed rotation of the spindle motor 31 drives the milling cutter to rotate, so that the second polishing device 12 can process the inner mold line of the keychain. Finally, the key chain after processing the outer parting line and the inner parting line is moved to the third polishing device 13 arranged on one side of the second feeding track 10 through the second feeding device 11. The third polishing device 13 is a circular polishing wheel that polishes the outer contour of the key chain.

[0024] The present invention has a high degree of automation, and the polishing work does not require manual operation, thus avoiding the problems of slow manual operation and low efficiency. The present invention enables key chains to be accurately and quickly arranged and compactly fed according to a regular pattern. Multiple key chains can be polished simultaneously in each operation, with high work efficiency and accuracy, and saving labor costs. The key chains can be automatically polished by simply inputting a specified program on the console.

[0025] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
