Description

Technical Field

[0001] This utility model relates to a cup processing equipment, and more particularly to a cup polishing device with a rotating frame leveling function. Background Technology

[0002] A thermos is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a lid on top that is tightly sealed. The vacuum insulation layer can slow down the heat dissipation of the water or other liquids inside, so as to achieve the purpose of keeping the water warm. When manufacturing stainless steel thermoses, the body of the thermos needs to be polished.

[0003] For example, the polishing device of the dual-station cup polishing equipment disclosed in patent CN220362370U includes a base plate, a gantry frame slidably connected to the base plate along the X-axis direction, slide blocks slidably connected to both sides of the gantry frame along the Z-axis direction of the base plate, a rotating seat rotatably connected between the slide blocks on both sides via a shaft, two polishing wheels of the same size and structure are provided on the rotating disk, and a first motor is provided to drive the two polishing wheels to rotate simultaneously. The two polishing wheels are arranged along the Y-axis direction of the base plate, and the centers of the two polishing wheels are both located on the axis formed along the Y-axis of the base plate. A sanding belt adjusting wheel is slidably connected to the rotating disk, and a sanding belt is sleeved on the two polishing wheels and the sanding belt adjusting wheel. The sanding belt adjusting wheel is connected to a first cylinder that drives its movement.

[0004] To improve processing efficiency, existing cup polishing devices typically use multiple polishing wheels on a rotating disk to simultaneously polish multiple insulated cups. During equipment assembly, due to assembly errors and other factors, there may be slight front-to-back position differences (e.g., a deviation of 1mm) on both sides of the gantry frame, and slight height differences (e.g., a deviation of 1mm) in the sliding blocks on both sides of the gantry frame. This results in a slight misalignment of the rotating disk between the two blocks, causing different polishing areas on the rotating disk to achieve varying degrees of polishing on the cups, or polishing different areas of the cups on different polishing areas. Existing devices, due to the gantry frame's position in the X-axis direction... The movement of the slide and the slider in the Z-axis direction is controlled by a single drive mechanism, making it impossible to adjust the position of one side. Existing adjustment methods involve disassembling and reinstalling the equipment for adjustment, or adding shims between the slide and the slider to eliminate the difference in front-to-back or height positions of the two slides, thereby aligning the rotary table installed between the two slides. These adjustment methods are quite cumbersome. In addition, since the drive mechanism for moving the slide in the Z-axis direction is located on one side, the movement of the slide on one side drives the movement of the slide on the other side. This drive method has poor stability, and the driven parts may vibrate during the driving process. Utility Model Content

[0005] Based on the above, there may be a slight difference in front-to-back position on both sides of the gantry frame, or there may be a slight difference in height on the sliding blocks on both sides of the gantry frame, which may cause the rotating disk to be slightly misaligned, making adjustment inconvenient. In addition, the single-sided drive method has poor stability, and the driven part may vibrate during the drive movement. Therefore, this utility model provides a cup polishing device with a rotating frame leveling function.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cup polishing device with a rotating frame leveling function, including a frame, a gantry, a slide block, and a rotating frame. The left and right sides of the frame are provided with first slide rails extending horizontally along the X-axis. The left and right sides of the gantry are slidably connected to the first slide rails on both sides. The left and right sides of the gantry are connected with displacement drive mechanisms for driving its movement in the X-axis direction. The left and right sides of the gantry are provided with second slide rails extending vertically along the Z-axis. There are two slide blocks, which are slidably connected to the second slide rails on both sides. The two slide blocks are connected with lifting drive mechanisms for driving their movement in the Z-axis direction. The rotating frame is mounted between the two slide blocks and can rotate around the C-axis on the slide blocks. The two sides of the rotating frame are connected with first rotation drive mechanisms for driving its rotation. The rotating frame is provided with at least two polishing wheels and a second rotation drive mechanism for driving the polishing wheels to rotate. The polishing wheels on the rotating frame are arranged in a straight line.

[0007] A further preferred embodiment of this utility model is as follows: the displacement driving mechanism includes a first drive motor, a first rack and a first gear, the first rack is fixed on the frame, the first drive motor is fixed on the gantry frame, the first gear is connected to the output shaft of the first drive motor, and the first gear meshes with the first rack.

[0008] A further preferred embodiment of this utility model is as follows: the lifting drive mechanism includes a second drive motor, a second rack and a second gear. The second rack is fixed on the gantry frame, the second drive motor is fixed on the slide block, the second gear is connected to the output shaft of the second drive motor, and the second gear meshes with the second rack.

[0009] A further preferred embodiment of this utility model is as follows: the first rotary drive mechanism includes a third drive motor, which is mounted on a slide. The output shaft of the third drive motor is connected to the rotary frame. The axis of the output shaft of the third drive motor is the C-axis, which is perpendicular to both the X-axis and the Z-axis.

[0010] A further preferred embodiment of this invention is that the polishing wheels on the rotating frame are arranged sequentially along the C-axis.

[0011] A further preferred embodiment of this utility model is as follows: the polishing wheel has four wheels, and a second rotary drive mechanism drives two polishing wheels to rotate. The second rotary drive mechanism includes a fourth drive motor. An active synchronous wheel is connected to the output shaft of the fourth drive motor, and a driven synchronous wheel is coaxially connected to the polishing wheel. The active synchronous wheel and the two driven synchronous wheels are driven by a synchronous belt.

[0012] A further preferred technical solution of this utility model is as follows: the gantry frame includes a top frame, a bottom frame, and two side frames. The two side frames are respectively connected to the two sides of the top frame and the bottom frame. The bottom frame is slidably connected to the first slide rails on both sides via a first slider. Two second slide rails are respectively set on the side frames on both sides. The slide block is slidably connected to the second slide rail via a second slider. The rotating frame rotates between the top frame, the bottom frame, and the two side frames.

[0013] A further preferred technical solution of this utility model is: the gantry frame is a square frame.

[0014] A further preferred embodiment of this invention is that the outer circumferential surface of the polishing wheel is used as the grinding area.

[0015] A further preferred technical solution of this utility model is as follows: a tensioning wheel is provided on the rotating frame, and an abrasive belt is fitted on the tensioning wheel and the polishing wheel. The abrasive belt serves as the grinding part, and the abrasive belt can be driven to move when the polishing wheel rotates.

[0016] Compared with the prior art, the advantages of this utility model are that displacement drive mechanisms are set on the left and right sides of the gantry for driving the gantry to move in the X-axis direction, and each slide on both sides is individually connected to a lifting drive mechanism for driving it to move in the Z-axis direction. A first rotation drive mechanism is connected on the left and right sides of the rotating frame to drive the rotating frame to rotate around the C-axis on the slide. When the equipment is assembled, if there is a slight front-to-back position difference between the left and right sides of the gantry due to assembly errors, the displacement drive mechanism on one side can be used to drive one side of the gantry to move slightly in the X-axis direction to eliminate the front-to-back position difference. If there is a slight height difference between the slides on both sides due to assembly errors, the lifting drive mechanism on one side can be used to drive one side of the slide to move up and down to eliminate the height difference between the two slides. This allows for the adjustment of the rotating frame installed between the two slides, which is convenient and quick. Furthermore, the gantry, the two slides, and the rotating frame are all equipped with two drive mechanisms to drive the movement, making the forces on both sides more balanced during operation, thereby improving the stability of the operation and reducing the vibration of the driven parts during movement.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] Figures 1-8 As shown, the automatic polishing machine includes a cup body polishing device 2 and a cup body clamping device 3. The cup body clamping device 3 is opposite to the cup body polishing device 2. The cup body clamping device 3 is used to clamp and fix the insulated cup body that needs to be polished, and then the cup body polishing device 2 polishes the clamped insulated cup body.

[0030] Figures 2-5 As shown, the cup polishing device 2 includes a frame 1, a gantry 6, a slide block 15, and a rotating frame 9. The frame 1 has a first slide rail 4 extending horizontally along the X-axis on both its left and right sides. The gantry 6 is slidably connected to the first slide rail 4 on both sides. The gantry 6 is connected to a displacement drive mechanism 5 for moving in the X-axis direction on both sides. The gantry 6 is provided with a second slide rail 24 extending vertically along the Z-axis on both sides. There are two slide blocks 15, which are slidably connected to the second slide rail 24 on both sides. The two slide blocks 15 are connected to a lifting drive mechanism 7 for moving in the Z-axis direction. The rotating frame 9 is mounted between the two slide blocks 15 and can rotate around the C-axis 25 on the slide blocks 15. The rotating frame 9 is connected to a first rotation drive mechanism 8 for driving its rotation on both sides. The rotating frame 9 is provided with at least two polishing wheels 10 and a second rotation drive mechanism 11 for driving the polishing wheels 10 to rotate. The polishing wheels 10 on the rotating frame 9 are arranged in a straight line.

[0031] This patent provides displacement drive mechanisms 5 on the left and right sides of the gantry 6 for moving the gantry 6 in the X-axis direction. Each slide 15 on both sides is individually connected to a lifting drive mechanism 7 for moving it in the Z-axis direction. A first rotation drive mechanism 8 is connected to the left and right sides of the rotating frame 9 to drive the rotating frame 9 to rotate around the C-axis 25 on the slide 15. When the equipment is assembled, if there is a slight front-to-back position difference between the left and right sides of the gantry 6 due to assembly errors, the displacement drive mechanism 5 on one side can be used to drive one side of the gantry 6 to move slightly in the X-axis direction to eliminate the front-to-back position difference. Similarly, if there is a slight height difference between the slides 15 on both sides due to assembly errors, the lifting drive mechanism 7 on one side can be used to drive the lifting of one slide 15. The movement eliminates the height difference between the two slides 15, thereby adjusting the rotating frame 9 installed between the two slides 15. The adjustment is convenient and quick. The gantry 6, the two slides 15, and the rotating frame 9 are all equipped with two drive mechanisms to drive the movement. When it is necessary to control the polishing wheel 10 to move along the X-axis, the displacement drive mechanisms 5 on both sides simultaneously drive the gantry 6 to move. When it is necessary to control the polishing wheel 10 to move along the Z-axis, the lifting drive mechanisms 7 on both sides simultaneously drive the slides 15 on both sides to move in the Z-axis direction. When it is necessary to control the polishing wheel 10 to swing up and down, the first rotation drive mechanisms 8 on both sides simultaneously drive the rotating frame 9 to rotate around the C-axis 25, so that the force on both sides is more balanced, thereby improving the stability of the operation and reducing the vibration of the driven parts during the movement.

[0032] The displacement drive mechanism 5 is a conventional linear drive mechanism. Preferably, the displacement drive mechanism 5 includes a first drive motor 14, a first rack 13, and a first gear 16. The first rack 13 is fixed on the frame 1, the first drive motor 14 is fixed on the gantry 6, and the first gear 16 is connected to the output shaft of the first drive motor 14 and meshes with the first rack 13. The forward or reverse rotation of the output shaft of the first drive motor 14 controls the gantry 6 to move linearly back and forth along the X-axis on the frame 1.

[0033] The first drive motor 14 is a geared motor, such as a geared motor from the brand Aner.

[0034] The lifting drive mechanism 7 is a conventional linear drive mechanism. Preferably, the lifting drive mechanism 7 includes a second drive motor 17, a second rack 22, and a second gear 18. The second rack 22 is fixed on the gantry frame 6, the second drive motor 17 is fixed on the slide 15, and the second gear 18 is connected to the output shaft of the second drive motor 17 and meshes with the second rack 22. The slide 15 moves up and down linearly along the Z-axis on the gantry frame 6 by rotating the output shaft of the second drive motor 17 in the forward or reverse direction.

[0035] The second drive motor 17 is a geared motor, such as a geared motor from the K series, brand name Saichi Transmission.

[0036] The first rotary drive mechanism 8 includes a third drive motor 23, which is mounted on a slide 15. The output shaft of the third drive motor 23 is connected to the rotary frame 9. The axis of the output shaft of the third drive motor 23 is the C-axis 25, which is perpendicular to both the X-axis and the Z-axis. The rotary frame 9 is controlled to swing up or down by rotating the output shaft of the third drive motor 23 in either the forward or reverse direction.

[0037] The polishing wheels 10 installed on the rotating frame 9 are arranged sequentially along the C-axis 25, so that the cup polishing device 2 can simultaneously polish the insulated cups fixed in a row on the cup clamping device 3 to improve processing efficiency. This arrangement of the structure ensures that the movements of each polishing wheel 10 are consistent when the gantry 6 moves along the X-axis, the slide 15 moves along the Z-axis, and the rotating frame 9 swings around the C-axis 25, so that polishing work can be performed simultaneously.

[0038] Figure 7 As shown, preferably, there are four polishing wheels 10. A second rotary drive mechanism 11 drives two polishing wheels 10 to rotate. The second rotary drive mechanism 11 includes a fourth drive motor 29. An active synchronous wheel 30 is connected to the output shaft of the fourth drive motor 29. A driven synchronous wheel 32 is coaxially connected to the polishing wheel 10. The active synchronous wheel 30 and the two driven synchronous wheels 32 are driven by a synchronous belt 31.

[0039] This equipment can be used for two processing steps: grinding and waxing / polishing.

[0040] Figure 6 As shown, when used for polishing, an abrasive belt 28 is fitted on the polishing wheel 10, and a tensioning wheel 27 is provided on the rotating frame 9 to tension the abrasive belt 28 by the auxiliary polishing wheel 10. The abrasive belt 28 serves as the polishing part, and the polishing wheel 10 can drive the abrasive belt 28 to move and polish the body of the thermos cup when it rotates.

[0041] Figure 8 As shown, when used for waxing and polishing, the outer peripheral surface of the polishing wheel 10 is used as the polishing part. The rotating frame 9 is equipped with a waxing mechanism 33 for waxing the outer peripheral surface of the polishing wheel 10. The waxing mechanism 33 includes a linear displacement component 34, on which a displacement frame 35 is provided. The wax strip 36 is mounted on the displacement frame 35. The linear displacement component 34 drives the displacement frame 35 to move back and forth in a linear motion. The displacement frame 35 drives the wax strip 36 to move, so that the wax strip 36 makes a reciprocating motion of contacting and moving away from the polishing wheel 10. When the wax strip 36 contacts the polishing wheel 10, it coats the outer peripheral surface of the polishing wheel 10 with wax, which is used by the polishing wheel 10 to polish the body of the thermos cup.

[0042] The linear displacement component 34 is a conventional linear displacement drive device in the field, such as an electric cylinder, a motor lead screw module, etc.

[0043] Figure 5 As shown, the gantry frame 6 includes a top frame 21, a bottom frame 19, and two side frames 20. The two side frames 20 are respectively connected to the top frame 21 and the bottom frame 19 on both sides. The bottom frame 19 is slidably connected to the first slide rails 4 on both sides via the first slider 12. The two second slide rails 24 are respectively set on the side frames 20 on both sides. The slide block 15 is slidably connected to the second slide rail 24 via the second slider 26. The rotating frame 9 rotates between the top frame 21, the bottom frame 19, and the two side frames 20.

[0044] The aforementioned second rack 22 is mounted on the side frame 20.

[0045] Preferably, the gantry frame 6 is a square frame.

[0046] There is a certain gap between the slider and the slide rail, which allows the gantry 6 and the slide blocks 15 on both sides to move on one side during adjustment.

[0047] The above describes the cup polishing device with rotating frame leveling function provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
