Description

Technical Field

[0001] The present invention relates to a device for polishing the outer wall of a vacuum cup body, and particularly to an automatic polishing device for a vacuum cup body. Background Art

[0002] A vacuum cup is generally a water container made of ceramics or stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can slow down the heat dissipation of liquids such as water inside, so as to achieve the purpose of heat preservation.

[0003] After the existing stainless steel vacuum cup body is formed, the outer surface of the stainless steel cup body needs to be polished. As Figure 1 shown, because the polishing standards of the cup mouth and the cup body are different, they need to be polished separately. The cup mouth part (i.e., part c) of the cup body is polished, and then the cup body part (i.e., part d) is polished.

[0004] After the stainless steel cup body is formed, a weld seam will be formed on the cup body. First, the weld seam needs to be polished. Workers place the formed cup body on the grinding equipment to polish the weld seam; then the outer surface of the cup body is rough processed by another grinding equipment, and then the cup body is polished again by another equipment. Finally, the cup body is polished for the last time by a fine polishing equipment to achieve the required polishing accuracy. At the same time, the cup mouth part of the cup body also needs to be polished, and the cup mouth also needs to be polished through multiple processes.

[0005] In this way, cup body polishing requires multiple devices, and each time the cup body needs to be taken out of one device and then placed into another device. Multiple devices occupy a large space and the working efficiency is very low.

[0006] A polishing device for a vacuum cup body with the publication number of CN207873933U belongs to the technical field of polishing machines, including a frame, a base, a polishing device, and a rotating device. Its characteristics are: the rotating device includes a motor one, a turntable, a sleeve rod, a cylinder one, and a pressing block. The sleeve rod is arranged at the upper end of the turntable. The polishing device includes a fixing plate, a grinding wheel, a motor two, a motor three, a belt, a belt pulley, a tension spring, a cylinder two, and a supporting plate.

[0044] The preferred embodiments of the present invention will be described in detail below 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.

[0045] It should be noted that similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0046] The automatic polishing equipment for the cup body of a heat-insulated cup includes a bottom plate 1. The shape of the bottom plate 1 is disc-shaped. A plurality of support feet 101 are provided at the bottom of the bottom plate 1. Preferably, the number of the support feet 101 is eight, and the eight support feet 101 are evenly distributed near the outer edge of the bottom of the bottom plate 1.

[0047] A main motor 102 is provided on the bottom plate 1. The output end of the main motor 102 is connected to a turntable 2. The axis of the turntable 2 is coaxial with the axis of the bottom plate 1. The main motor 102 drives the turntable 2 to rotate on the bottom plate 1. Further, the main motor 102 is equipped with a first speed reducer 103. The main motor 102 is connected to the turntable 2 through the first speed reducer 103, and the turntable 2 is rotatably connected to the speed reducer 103.

[0048] A notch 104 is provided at the outer edge of the bottom plate 1. The notch 104 is a placement station. The notch 104 is for a person to stand. A person can stand at the notch 104 to operate the fixture on the turntable 2, which is convenient for people to operate.

[0049] A plurality of fixture assemblies 3 are provided on the turntable 2. The structures of the plurality of fixture assemblies 3 are the same. Further, the fixture assembly 3 includes an upper fixture 301, a lower fixture 302, and a frame body 303. The frame body 303 is vertically arranged and fixedly connected to the turntable 2. The upper fixture 301 is provided on the frame body 303 and can move along the axial direction of the turntable 2 on the frame body 303. The lower fixture 302 is provided on the turntable 2, and the lower fixture 302 can rotate along its own axis.

[0050] Further, a sliding connection seat 304 is provided on the frame body 303. The sliding connection seat 304 can move along the axial direction of the turntable 2 on the frame body 303. The upper fixture 302 is connected to the sliding connection seat 304. Preferably, the number of the sliding connection seats 304 is two. The sliding connection seats 304 can be slidably connected to the frame body 303 by a sliding connection method using a slide rail, or can be slidably connected to the frame body 303 by a connection method using a lead screw and a lead screw nut. Preferably, two optical axes 305 are provided on the frame body 303. Both of the two sliding connection seats 304 are sleeved on the optical axes 305 and can slide along the optical axes 305. A fixture cylinder 306 is provided on the sliding connection seat 304. The fixture cylinder 306 can drive the sliding connection seat 304 to slide on the optical axes 305.

[0051] The jig cylinder 306 drives the upper jig 301 to approach / separate from the lower jig 302. When the upper jig 301 separates from the lower jig 302 and the upper jig 301 and the lower jig 302 are in the open state, the cup body can be placed on the lower jig 302 or removed from the lower jig 302. Then the jig cylinder 306 drives the upper jig 301 to move closer to the lower jig 302 to clamp the cup body between the upper jig 301 and the lower jig 302.

[0052] An adjusting screw rod 307 is provided on the frame body 303. The adjusting screw rod 307 is passed through the sliding connection seat 304. The top of the adjusting screw rod 307 is fixedly connected with an adjusting wrench 308. The adjusting wrench 308 drives the adjusting screw rod 307 to rotate. The rotation of the adjusting screw rod 307 can drive the sliding connection seat 304 to slide on the optical axis 305. The adjusting wrench 308 is rotated manually. If the jig cylinder 306 fails, the sliding connection seat 304 can be manually driven to slide so as to remove the cup body clamped between the upper and lower jigs.

[0053] The upper jig 301 is rotatably connected to the sliding connection seat 304 along its own axis. Preferably, a first bearing 309 is provided between the upper jig 301 and the sliding connection seat 304. After the upper jig 301 clamps the cup body 302 on the lower jig 302, the rotation of the lower jig 302 drives the cup body to rotate, and the upper jig 301 rotates simultaneously.

[0054] The lower jig 302 is rotatably connected to the turntable 2. Preferably, a second bearing 310 is provided between the lower jig 302 and the turntable 2. The bottom end of the lower jig 302 is connected with a pulley 311. Each pulley 311 is driven to rotate by a driving mechanism 4, and the rotation of the pulley 311 drives the lower jig 302 to rotate along its own axis.

[0055] The above driving mechanism 4 has a clutch device. The clutch device includes a driving wheel 312. The centers of the pulleys 311 at the bottoms of the lower jigs 302 in each jig assembly 3 are located on the side b of a circle a. The above driving wheel 312 is located outside the side b of the circle a. That is to say, the distances between each pulley 311 and the axis of the turntable 2 are equal, and the distance between the driving wheel 312 and the axis of the turntable 2 is greater than the distances between each pulley 311 and the axis of the turntable 2.

[0056] The driving mechanism 4 further includes a pulley motor 401, a driving wheel 402, a driven wheel 403 and a first belt 404. The pulley motor 401 is provided on the bottom plate 1. The driving wheel 402 is fixedly connected to the output end of the pulley motor 401. A support frame 405 is provided on the bottom plate 1. The driven wheel 403 is rotatably connected to the support frame 405. A second belt 406 is sleeved on the driving wheel 402 and the driven wheel 403. The pulley motor 401 drives the driving wheel 402 to rotate, and the driving wheel 402 drives the driven wheel 403 to rotate.

[0057] The driving wheel 312 is rotatably connected to the support frame 405, and the driving wheel 312 is fixedly connected to the driven wheel 403. That is, the driving wheel 312 rotates with the rotation of the driven wheel 403. The first belt 404 is sleeved on the driving wheel 312 and each pulley 311. The pulley motor 401 drives the driving wheel 312 to rotate through the driving wheel 402 and the driven wheel 403. The driving wheel 312 drives each pulley 311 to rotate through the first belt 404. And, since the driving wheel 312 is located outside the edge of the circle formed by each pulley 311, therefore, there is always a pulley 311 that does not contact the first belt 404, so that several pulleys 311 can be made not to rotate, achieving the effect of clutch.

[0058] A plurality of grinding wheel cup body grinding assemblies 5, sand belt cup body grinding assemblies 6 and cup mouth grinding assemblies 7 are arranged around the turntable 2 on the bottom plate 1. The total number of the grinding wheel cup body grinding assemblies 5, sand belt cup body grinding assemblies 6 and cup mouth grinding assemblies 7 is one less than the number of the fixture assemblies 3. Each grinding assembly corresponds to one fixture assembly 3. The extra fixture assembly 3 corresponds to the notch 104 and is located at the placement station. When each grinding assembly processes the cup body on the corresponding fixture assembly 3, the extra fixture assembly 3 located at the placement station performs the operation of replacing the cup body, taking down the ground cup body, and at the same time putting the cup body to be ground onto the fixture assembly 3.

[0059] Preferably, the number of the grinding wheel cup body grinding assemblies 5 is two, the number of the sand belt cup body grinding assemblies 6 is three, and the number of the cup mouth grinding assemblies 7 is three. The total number of the three is eight. Therefore, the number of the fixture assemblies 3 is nine.

[0060] Preferably, the included angle between each fixture assembly 3 is 40°, that is, the angle of each rotation of the turntable 2 is 40°.

[0061] For the grinding wheel cup body grinding assembly 5, the sand belt cup body grinding assembly 6 and the cup mouth grinding assembly 7, linear driving assemblies for driving their movement are provided between the above three and the bottom plate 1. The linear driving assemblies can be used to drive the above grinding assemblies to move along the radial direction of the turntable 2, and the structures of the linear driving assemblies of each grinding assembly are the same and the sizes are variable, with certain changes according to the sizes of the grinding assemblies.

[0062] The linear driving assembly can be in the form of cylinder driving, motor driving, etc. Preferably, the linear driving assembly adopts the driving mode of a servo motor.

[0063] The linear drive assembly includes a first servo motor 801 and a lead screw 802. A first slider 803 is provided at the bottom of each of the above-mentioned grinding assemblies. A first slide rail 804 with the same number as the grinding assemblies is provided on the bottom plate 1. The first slider 803 is slidably connected to the first slide rail 804. A first lead screw nut 805 for driving its movement is provided at the bottom of each grinding assembly. The lead screw 802 is passed through the first lead screw nut 805 and is threadedly connected thereto. The first servo motor 801 drives the lead screw 802 to rotate. The rotation of the lead screw 802 drives the first lead screw nut 805 to move along the radial direction of the turntable 2, thereby driving the grinding assembly to move along the radial direction of the turntable 2. By moving the grinding assembly, the grinding assembly can be made to approach or move away from the cup held by the fixture assembly 3. When the grinding assembly approaches the fixture assembly 3, the grinding assembly grinds the cup. When the grinding assembly moves away from the fixture assembly 3, the turntable 2 rotates to drive the fixture assembly 3 to move to the next working station.

[0064] The grinding assembly for the cup body 5 includes a first gantry 501, a grinding wheel mounting plate 502, a grinding wheel 503 and a first motor 504. The first gantry 501 can move along the radial direction of the turntable 2, which is achieved by driving and moving through the above-mentioned linear drive assembly. A first connecting seat 505 that can move along the axial direction of the turntable 2 is provided on the first gantry 501. The grinding wheel mounting plate 502 is rotatably connected to the first connecting seat 505. The grinding wheel 503 is rotatably connected to the grinding wheel mounting plate 502 along its own axis. The first motor 504 is fixedly connected to the grinding wheel mounting plate 502 and can drive the grinding wheel 503 to rotate. Preferably, the number of the first connecting seats 505 is two, and the two first connecting seats 502 are respectively connected to both sides of the grinding wheel mounting plate 502.

[0065] Further, at the center of the top of the first gantry 501, there are two first synchronous pulleys 506.

[0067] Preferably, the rotation axis of the grinding wheel mounting plate 502 intersects with the rotation center line of the grinding wheel 503, so that when the grinding wheel mounting plate 502 rotates by the same angle, the movement range of the grinding wheel plate 502 is minimized to the greatest extent, and the overall volume of the equipment is minimized to the greatest extent.

[0068] The grinding wheel 503 and the first motor 504 are arranged side by side on the grinding wheel mounting plate 502. On the grinding wheel 503, there is a grinding wheel main shaft 513.

The second connecting seat 606 is slidably connected to the third slide rail 613. The third servo motor 608 drives the second ball screw 609 to rotate through the synchronous belt wheel. The rotation of the second ball screw 609 drives the third screw nut 612 to move along the axial direction of the turntable 2 on the second gantry 601, and the third screw nut 612 drives the second connecting seat 606 to move along the axial direction of the turntable 2 on the second gantry 601.

[0071] A sixth servo motor 618 is provided on one of the second connecting seats 606.

[0072] Preferably, the rotation axis of the abrasive belt mounting plate 602 intersects with the rotation center line of the rubber wheel 603. When the abrasive belt mounting plate 602 rotates by the same angle, the movement range of the abrasive belt plate 602 is minimized to the greatest extent, and the overall volume of the equipment is minimized to the greatest extent.

[0073] The rubber wheel 603 and the second motor 605 are arranged side by side on the abrasive belt mounting plate 602. A rubber wheel main shaft 614 is provided on the rubber wheel 603, a seventh synchronous pulley 615 is provided on the rubber wheel main shaft 614, an eighth synchronous pulley 616 is provided at the output end of the second motor 605, and a fourth synchronous belt 617 is sleeved on the seventh synchronous pulley 615 and the eighth synchronous pulley 616.

[0074] A tension pulley 620 and a fixed pulley 621 are further provided on the abrasive belt mounting plate 602.

The connecting plate 623 drives the tension pulley 620 to move. When assembling the abrasive belt 604, first move the tension pulley 620 close to the rubber wheel 603 through the tension pulley driving device so that the abrasive belt 604 can be easily sleeved on the rubber wheel 603, the fixed pulley 621 and the tension pulley 620. After sleeving, the driving cylinder 622 works to drive the connecting plate 623 to move on the abrasive belt mounting plate 602. The connecting plate 623 drives the tension pulley 620 to move and move away from the rubber wheel 603, so that the abrasive belt 604 can be supported on the rubber wheel 603, the fixed pulley 621 and the tension pulley 620 to complete the assembly.

[0075] The structures of the grinding wheel cup body grinding assemblies 5 are all the same, and the difference lies in the specifications of the grinding wheels 503. The sand surface of the grinding wheel 503 in the subsequent process is finer than the sand surface of the abrasive belt 503 in the previous process.

[0076] Similarly, the structures of each abrasive belt cup body grinding assembly 6 are the same, and the difference lies in the specifications of the abrasive belt 604. The abrasive belt 604 in the previous process is rougher and first rough-grinds the cup body, and the abrasive surface of the abrasive belt 604 in the subsequent process gradually becomes finer.

[0077] The abrasive surface of the grinding wheel 503 is finer than that of the abrasive belt 604. Therefore, the processes of the abrasive belt cup body grinding assembly 6 are all in front of the grinding wheel cup body grinding assembly 5.

[0078] The cup mouth grinding assembly 7 includes a third gantry 701, a fiber wheel mounting plate 702, a fiber wheel 703, and a third motor 704.

[0080] The fiber wheel 703 and the third motor 704 are arranged side by side on the fiber wheel mounting plate 702. A fiber wheel main shaft 709 is provided on the fiber wheel 703. A ninth synchronous pulley 710 is provided on the fiber wheel main shaft 709. A tenth synchronous pulley 711 is provided at the output end of the third motor 704. A fifth synchronous belt 712 is sleeved on the ninth synchronous pulley 710 and the tenth synchronous pulley 711. The third motor 704 drives the fiber wheel 703 to rotate through the synchronous pulley.

[0081] The structures of each cup mouth and cup body grinding assembly 7 are the same, and the difference lies in the specifications of the fiber wheel 703. The abrasive surface of the fiber wheel 703 in the subsequent process is finer than that of the fiber wheel 703 in the previous process.

[0082] The arrangement order of each grinding component is as follows: 1. Belt cup body grinding component one; 2. Belt cup body grinding component two; 3. Cup mouth grinding component one; 4. Belt cup body grinding component three; 5. Cup mouth grinding component two; 6. Grinding wheel cup body grinding component one; 7. Cup mouth grinding component three; 8. Grinding wheel cup body grinding component two.

[0083] The placement station is located between the belt cup body grinding component one and the grinding wheel cup body grinding component two.

[0084] The driving wheel 312 is located at the side of the belt cup body grinding component one. When the fixture component 3 is in the position corresponding to the placement station and the belt cup body grinding component one, the first belt 404 does not contact the pulley 311 of the lower fixture among the two fixture components 3. In this way, when the fixture component 3 runs to these two positions, the lower fixture 302 will not rotate, that is, the cup body will not rotate.

[0085] The base 1 is also provided with a main driving device. The main driving device includes a rotating table 901, a clamping block 902 and a fourth motor 903. The fourth motor 903 is used to drive the rotation of the rotating table 901. The clamping block 902 is arranged on the rotating table 901 and can be used to clamp the bottom end of the lower fixture 302. The fourth motor 903 drives the rotation of the rotating table 901, and the rotating table 901 drives the fixture 302 to rotate by clamping the lower fixture 302 through the clamping block 902.

[0086] Due to the difference in the processing method of the cup body, some cup bodies are produced without weld seams, so weld seam grinding is not required. The main driving device can clamp the lower fixture so that the lower fixture can rotate without passing through the pulley and rotate through the main driving device.

[0087] During the processing process, taking one of the fixture components 3 as an example:

[0088] 1. The cup body is clamped on each fixture component 3. The manipulator is at the placement station, takes the processed cup body from the fixture component 3, then places the cup body to be processed on the lower fixture 302 of the fixture component 3, and then the fixture cylinder 306 drives the sliding connection seat 304 to move downward, that is, drives the upper fixture 301 to move downward to clamp the cup body to be processed on the upper fixture component 3. Therefore, when the fixture component 3 is at the placement station, the fixture component 3 does not need to rotate.

[0089] 2. The turntable 2 rotates 40°, and the fixture component 3 moves to the position corresponding to the belt cup body grinding component one. The belt cup body grinding component one grinds the weld seam of the cup body on the fixture component 3. Therefore, when the fixture component 3 is at the position of the belt cup body grinding component one, the fixture component 3 does not need to rotate.

[0090] 3. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the second sanding cup body sanding assembly. At this time, the pulley 311 at the bottom of the lower fixture 303 in the fixture assembly 3 contacts the first belt 404. The first belt 404 drives the pulley 311 to rotate, and the pulley 311 drives the lower fixture 303 to rotate, that is, the cup body to be processed rotates accordingly. Then, the second sanding cup body sanding assembly sands the cup body.

[0091] 4. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the first cup mouth sanding assembly. The first cup mouth sanding assembly roughly sands the cup mouth position of the cup body.

[0092] 5. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the third sanding cup body sanding assembly. The sand surface of the sand belt of the third sanding cup body sanding assembly is finer than the sand surface of the sand belt of the second sanding cup body sanding assembly. The third sanding cup body sanding assembly further sands the cup body.

[0093] 6. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the second cup mouth sanding assembly. The fiber wheel of the second cup mouth sanding assembly is finer than the fiber wheel of the first cup mouth sanding assembly. The second cup mouth sanding assembly further sands the cup mouth.

[0094] 7. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the first grinding wheel cup body grinding assembly. The sand surface of the grinding wheel of the first grinding wheel cup body grinding assembly is finer than the sand surface of the sand belt of the third sanding cup body sanding assembly. The first grinding wheel cup body grinding assembly deeply polishes the cup body.

[0095] 8. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the third cup mouth sanding assembly. The fiber wheel of the third cup mouth sanding assembly is finer than the fiber wheel of the second cup mouth sanding assembly. The third cup mouth sanding assembly finally sands the cup mouth to polish the cup mouth into a mirror effect.

[0096] 9. The turntable 2 continues to rotate 40°, and the fixture assembly 3 moves to the position corresponding to the second grinding wheel cup body grinding assembly. The sand surface of the grinding wheel of the second grinding wheel cup body grinding assembly is finer than the sand surface of the grinding wheel of the first grinding wheel cup body grinding assembly. The second grinding wheel cup body grinding assembly performs the last sanding on the cup body.

[0097] 10. The turntable 2 continues to rotate 40°, and the fixture assembly 3 returns to the placement station. The manipulator removes the processed cup body from the fixture assembly 3, and then places the cup body to be processed into the fixture assembly 3, repeating the above processing process.

[0098] The cup body is simultaneously clamped on the fixture assembly 3, and each grinding assembly corresponds to each fixture assembly 3. Each grinding assembly processes the cup body simultaneously. When the grinding assembly processes the cup body, the fixture assembly 3 located at the placement station performs the work of changing parts simultaneously through the manipulator, which is more time-saving and labor-saving.
