DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0031] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Embodiment 1, as Figure 1-Figure 11 As shown, according to an embodiment of the present application, a cup rim polishing device for a ceramic cup with a lid comprises a mounting table 1, on which a cup lid clamping mechanism 2 with a lifting function is provided, so as to clamp the cup lid and realize the lifting action, so that the cup lid and the cup rim can be abutted or separated. Specifically, the cup lid clamping mechanism 2 comprises a lifting member 21 fixed to the mounting table 1, a cup lid clamping member 22 is provided at the displacement end of the lifting member 21, and a force unloading assembly 23 is provided between the cup lid clamping member 22 and the displacement end of the lifting member 21. It should be noted that in the specific embodiment of the present application, the lifting member 21 can be an electric slide or other prior art with a linear displacement function.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the force unloading assembly 23 includes a fixed seat 231 fixedly connected to the displacement end of the lifting member 21, and an active displacement member and an elastic buffer member are arranged on the fixed seat 231. The active displacement member changes the elastic force of the elastic buffer member by changing its own displacement. The elastic buffer member is fixedly connected to the cup cover clamping member 22 and forms an elastic connection with the fixed seat 231 to realize the conversion of the abutting force between the cup cover and the cup mouth from rigidity to flexibility, thereby reducing the probability of damage between the cup cover and the cup mouth during the grinding process.

[0034] The cup body clamping piece 3 is rotatably disposed on the mounting platform 1 and is coaxial with the cup cover clamping piece 22 .

[0035] It should be noted that in the specific embodiment of the present application, the cup cover clamp 22 and the cup body clamp 3 can be existing technologies such as three-jaw chucks with central positioning and fixing.

[0036] In addition, the cup rim grinding device of a ceramic cup with a cover according to an embodiment of the present application also has the following additional technical features:

[0037] like Figure 1 and Figure 2 As shown, a support plate 11 is also fixedly connected to the bottom of the mounting platform 1 to support some components in the embodiment of the present application.

[0038] like Figure 2 and Figure 4 As shown, the displacement end of the lifting member 21 is fixedly connected to a mounting plate 211 , and the mounting plate 211 is fixedly connected to a fixing seat 231 .

[0039] like Figure 4 As shown, the active displacement member includes a lifting cylinder 232 and a pressure plate 234. The lifting cylinder 232 is fixedly connected to the fixed seat 231, and its telescopic end passes through the fixed seat 231. In this way, the lifting cylinder 232 will move along with the movement of the displacement end of the lifting member 21. The pressure plate 234 is fixedly connected to the telescopic end of the lifting cylinder 232. Therefore, the pressure plate 234 changes its own position while following the movement of the displacement end of the lifting member 21.

[0040] Furthermore, the elastic buffer member includes a guide rod 233 and an elastic member 235. The guide rod 233 is fixedly connected to the cup cover clamp 22 and slides through the pressure plate 234 and the fixed seat 231 in sequence. A limiting flange is provided at one end of the guide rod 233 extending out of the fixed seat 231 to prevent the guide rod 233 from slipping on the fixed seat 231. The elastic member 235 is sleeved on the guide rod 233, and its two ends are respectively abutted against the cup cover clamp 22 and the pressure plate 234.

[0041] Therefore, it can be understood that when grinding is not in progress, due to the action of gravity, the guide rod 233 is at the lowest position relative to the fixed seat 231. At this time, the lifting member 21 can change the overall position of the lifting cylinder 232, the pressure plate 234 and the cup cover clamp 22 through the displacement end. When the lifting cylinder 232 drives the pressure plate 234 to descend along the guide rod 233, it will squeeze the elastic member 235 to enhance the elastic force between the cup cover clamp 22 and the pressure plate 234. Conversely, when the pressure plate 234 rises, it will stretch the elastic member 235, thereby reducing the elastic force between the cup cover clamp 22 and the pressure plate 234 (when the tension on the elastic member 235 is less than the gravity of the object at its bottom, that is, when the elastic member 235 is stretched, the position of the cup cover clamp 22 remains unchanged).

[0042] It should be noted that the elastic member 235 can be a spring or the like in the prior art.

[0043] like Figure 1-Figure 3 As shown, the cup body clamp 3 is coaxially keyed to a rotating shaft 31, which passes through the mounting platform 1. A bearing seat 311 is sleeved on the rotating shaft 31, and the bearing seat 311 is fixed to the mounting platform 1. It should be noted that in the specific embodiment of the present application, two bearing seats 311 are arranged symmetrically, one is fixed on the bottom side of the mounting platform 1, and the other is installed on the upper side of the support plate 11, so as to achieve better axial positioning of the rotating shaft 31.

[0044] Furthermore, a protective cover 312 is coaxially arranged on the bottom side of the cup body clamp 3, and the protective cover 312 is fixedly connected to the mounting table 1. The rotating shaft 31 rotates through the protective cover 312. There is no contact between the cup body clamp 3 and the protective cover 312, that is, the protective cover 312 does not affect the rotation of the cup body clamp 3, and the protective cover 312 can prevent dirt in the grinding process from interfering with the rotating shaft 31.

[0045] Furthermore, a motor 32 is also provided on the mounting platform 1 , and the motor 32 provides rotational power for the cup body clamp 3 . A pulley assembly 321 is keyed to the output shaft of the motor 32 , and the other end of the pulley assembly 321 is keyed to the rotating shaft 31 .

[0046] The following describes the use process of a cup rim polishing device for a ceramic cup with a cover according to an embodiment of the present application with reference to the accompanying drawings:

[0047] During specific use, the cup cover is clamped on the cup cover clamping piece 22, and the cup body is clamped on the cup body clamping piece 3. The cup cover can be leveled by an external horizontal device before clamping to improve the grinding effect between the cup cover and the cup mouth. During this period, the pressure plate 234 can be driven by the lifting cylinder 232 to move on the guide rod 233 to change the extrusion or stretching range of the pressure plate 234 on the elastic member 235 below it, that is, to change the elastic force value of the cup cover clamping piece 22 relative to the fixed seat 231, and then the displacement end of the lifting piece 21 is moved to drive the cup cover to abut against the cup mouth below, and the motor 32 is started, and the pulley assembly 321 is driven to move. The movable shaft 31 rotates, which in turn drives the cup body clamping part 3 and the cup body thereon to rotate, so that grinding action occurs between the cup mouth and the cup cover. During this period, an external device can be used to provide grinding liquid to the grinding part to improve the grinding effect. The elastic contact between the cup cover and the cup mouth will enable the two to form flexible contact in the axial direction during the grinding process, that is, the cup cover can rise a certain amount in the axial direction and then fall, forming a "steady stream" type of grinding for the burrs, protrusions and other parts that need to be ground off, avoiding damage to the cup mouth or the cup cover due to the rigid contact between the cup cover and the cup mouth and the inability to form a "concession" between the two due to the relatively strong parts that need to be ground off.

[0048] Embodiment 2: In the related art, in the cup rim grinding device of a ceramic cup with a lid, since the cup body clamp 3 needs to rotate continuously during the grinding process, and the grinding between the cup lid and the cup rim requires both to remain coaxial, once axial deviation occurs, the grinding between the cup lid and the cup rim will fail or reduce the grinding effect.

[0049] According to some embodiments of the present application, Figure 2 , Figure 3 and Figure 5As shown, a compensation mechanism 4 is sleeved on the rotating shaft 31, and the compensation mechanism 4 includes: a compensation cylinder 41, a plurality of upper telescopic members 42, a plurality of lower telescopic members 43 and a pressure member 44. The compensation cylinder 41 is sleeved on the rotating shaft 31, and two floating plates are symmetrically arranged inside the compensation cylinder 41; the plurality of upper telescopic members 42 are fixedly connected to the mounting platform 1 and are evenly arranged circumferentially on the compensation cylinder 41, and their telescopic ends are sealed and slidably penetrate the compensation cylinder 41 and are fixedly connected to one of the floating plates; the plurality of lower telescopic members 43 are fixedly connected to the mounting platform 1 and are evenly arranged circumferentially on the compensation cylinder 41, and their telescopic ends are sealed and slidably penetrate the compensation cylinder 41 and are fixedly connected to the other floating plate; the pressure member 44 is fixedly sleeved on the rotating shaft 31, and the pressure member 44 and the two floating plates are sealed and slidably connected.

[0050] There is no contact between the compensation cylinder 41 and the rotating shaft 31 . It can be understood that there is no friction between the compensation cylinder 41 and the rotating shaft 31 .

[0051] A liquid storage chamber 411 is provided inside the compensation cylinder 41, and two joints 412 are connected on the side wall of the compensation cylinder 41. The two joints 412 are respectively connected to an external liquid supply device so that the liquid inside the compensation cylinder 41 can flow under pressure. It can be understood that a circulating liquid flow with a certain pressure can be formed inside the compensation cylinder 41 through the external liquid supply device, and the inflow and outflow of liquid can form related effects such as heat dissipation and impurity removal on the inside of the compensation cylinder 41.

[0052] An upper limit ring 413 and a lower limit ring 414 are fixedly connected to the inner wall of the compensation cylinder 41 , and the upper limit ring 413 and the lower limit ring 414 are symmetrically arranged.

[0053] Specifically, the two floating plates symmetrically arranged inside the compensation cylinder 41 are an upper sealing plate 421 and a lower sealing plate 431. The upper sealing plate 421 is fixedly connected to the telescopic end of the upper telescopic member 42, and the lower sealing plate 431 is fixedly connected to the lower telescopic member 43. The upper sealing plate 421 and the lower sealing plate 431 are respectively located on the side away from the upper limit ring 413 and the lower limit ring 414.

[0054] It can be seen that the upper sealing plate 421 is abutted against the upper limit ring 413 by the upper telescopic member 42, and the lower sealing plate 431 is abutted against the lower limit ring 414 by the lower telescopic member 43, so that the position of the compensation cylinder 41 on the rotating shaft 31 can be fixed.

[0055] like Figure 5 As shown, the pressure member 44 includes: a positioning tube 441, an extension plate 442 and a pressure ring 443. The positioning tube 441 is fixedly sleeved on the rotating shaft 31, that is, the position of the positioning tube 441 on the rotating shaft 31 is fixed and rotates with the rotation of the rotating shaft 31.

[0056] The extension plate 442 is fixedly sleeved on the outer wall of the positioning tube 441 and is centrally disposed on the outer wall of the positioning tube 441 .

[0057] The pressure ring 443 is fixedly connected to the peripheral side of the extension plate 442 and is symmetrically arranged on the extension plate 442. The pressure ring 443 is sealed and slidably connected to the upper sealing plate 421 and the lower sealing plate 431 on both sides of the top and bottom.

[0058] It can be understood that once the rotating shaft 31 is axially offset, it will drive the positioning cylinder 441 to be offset synchronously, and finally drive the pressure ring 443 to be axially offset, and squeeze the upper sealing plate 421 and the lower sealing plate 431 on the top and bottom sides of the pressure ring 443, that is, it will force the upper sealing plate 421 to have an upward displacement trend, and force the lower sealing plate 431 to have a downward displacement trend. The design of the extension plate 442 and the pressure ring 443 will transfer the axial offset of the rotating shaft 31 to the axial displacement of the upper sealing plate 421 and the lower sealing plate 431.

[0059] Therefore, during the normal grinding process of the cup cover and the cup mouth, once the rotating shaft 31 has a tendency to axially deviate, the axial deviation of the rotating shaft 31 will be transferred to the axial displacement of the upper sealing plate 421 and the lower sealing plate 431 through the extension plate 442 and the pressure ring 443. Specifically, Figure 5 As shown, when the rotating shaft 31 has an axial deviation tendency to the left, Figure 5 The left part of the pressure ring 443 in the middle will press the lower sealing plate 431 downward, forcing the lower sealing plate 431 to move downward, and the right part of the pressure ring 443 will push the upper sealing plate 421 upward, forcing the upper sealing plate 421 to move upward. In this way, the upper sealing plate 421 and the lower sealing plate 431 will respectively apply a reverse force to the telescopic ends of the upper telescopic member 42 and the lower telescopic member 43 corresponding to each other. In this way, the axial offset of the rotating shaft 31 can be controlled by the pressure at the telescopic ends of the upper telescopic member 42 and the lower telescopic member 43, thereby reducing the degree of axial offset and improving the grinding effect between the cup cover and the cup mouth. It can be understood that since the positioning cylinder 441 rotates along with the rotating shaft 31, friction will occur between the pressure ring 443 and the upper sealing plate 421 and the lower sealing plate 431, and the pressure ring 443 and the upper sealing plate 421 and the lower sealing plate 431 on the top and bottom sides thereof are sealed and slidably connected, and the liquid storage chamber 411 can form a circulating liquid flow with a certain pressure inside the compensation cylinder 41 through an external liquid supply device, so that the continuous inflow and outflow of liquid can form related effects such as heat dissipation and impurity removal on the inside of the compensation cylinder 41, thereby avoiding large wear caused by continuous friction between the pressure ring 443 and the upper sealing plate 421 and the lower sealing plate 431.

[0060] Embodiment three, in the related art, in the cup rim grinding device of the ceramic cup with a cover, there is continuous friction between the pressure ring 443 and the upper sealing plate 421 and the lower sealing plate 431, and the pressure ring 443 also needs to maintain a seal with the upper sealing plate 421 and the lower sealing plate 431, so the wear problem between the pressure ring 443 and the upper sealing plate 421 and the lower sealing plate 431 needs to be alleviated.

[0061] According to some embodiments of the present application, Figure 6-Figure 11 As shown, anti-wear mechanisms 5 are provided on both sides of the top and bottom of the pressure ring 443, and the anti-wear mechanisms 5 include: an upper positioning member 51, an upper anti-wear assembly 52, a lower positioning member 53 and a lower anti-wear assembly 54, the upper positioning member 51 is fixedly connected to the bottom side of the upper sealing plate 421; the upper anti-wear assembly 52 is rotatably arranged inside the upper positioning member 51, and is fixedly connected to the top end of the pressure ring 443; the lower positioning member 53 and the upper positioning member 51 are symmetrically arranged, and the lower positioning member 53 is fixedly connected to the top side of the lower sealing plate 431; the structure and size of the lower anti-wear assembly 54 are exactly the same as those of the upper anti-wear assembly 52, and it is rotatably arranged inside the lower positioning member 53, and is fixedly connected to the bottom end of the pressure ring 443.

[0062] Specifically, the upper positioning member 51 includes an inner positioning ring 511 and an outer positioning ring 512 which are arranged in concentric circles. The cross-sections of the inner positioning ring 511 and the outer positioning ring 512 are symmetrically L-shaped, with a spacing therebetween to allow the corresponding upper anti-wear component 52 or lower anti-wear component 54 to rotate therein and for the upper end or lower end of the pressure ring 443 to extend therein.

[0063] It should be noted that the pressure ring 443 does not contact the upper positioning member 51 and the lower positioning member 53 , so that the liquid can enter the interior of the upper positioning member 51 and the lower positioning member 53 .

[0064] Furthermore, the upper anti-wear component 52 includes a plurality of sliders 521 , a plurality of partitions 522 and a plurality of rubber rings 523 , and the upper anti-wear component 52 is in a closed ring shape as a whole.

[0065] Among them, multiple sliders 521 are arranged equidistantly around the circumference, and the sliders 521 are arranged in a fan shape; multiple partitions 522 are arranged equidistantly around the circumference, the partitions 522 are radially fixed to one side of the slider 521, and the sliders 521 are extended from both ends of the partitions 522. Multiple rubber rings 523 are respectively embedded in the outer side and the inner side of the slider 521. The two rubber rings 523 located on the inner and outer sides of the same slider 521 are respectively sealed and slidably connected to the inner walls of the inner positioning ring 511 and the outer positioning ring 512.

[0066] In this way, it can be understood that the sealing sliding contact between the entire upper anti-wear component 52 and the corresponding inner positioning ring 511 is actually the end of the partition plate 522 located on the outside and the rubber ring 523, and the sealing sliding contact between the upper anti-wear component 52 and the corresponding outer positioning ring 512 is actually the end of the partition plate 522 located on the inside and the rubber ring 523.

[0067] It should be noted that the slider 521 is provided with recessed parts 524 on both inner and outer sides along the radial direction, and grooves 525 are symmetrically provided in the recessed parts 524 in the upper and lower directions. The rubber ring 523 is embedded in the groove 525, and a distance is left between the inner wall of the rubber ring 523 and the recessed part 524.

[0068] Furthermore, the slider 521 is provided with an axial through hole 526 and a radial through hole 527 that are interconnected. The axial through hole 526 penetrates the slider 521 , and the radial through hole 527 penetrates the slider 521 and is covered by the rubber ring 523 .

[0069] Therefore, during specific use, since the liquid flow inside the liquid storage chamber 411 has pressure, the liquid will flow from the axial through hole 526 through the slider 521 into the corresponding upper positioning member 51 and the lower positioning member 53, and flow through the radial through hole 527 to the inner wall direction of the rubber ring 523 located on the inner and outer sides of the slider 521, and apply radial force to the rubber ring 523, so that a better sealing performance is formed between the rubber ring 523 and the inner wall of the corresponding upper positioning member 51 and the lower positioning member 53. It can be understood that during actual use, the upper positioning member 51 and the lower positioning member 53 are filled with liquid that is connected to the liquid storage chamber 411, and the top and bottom ends of the pressure ring 443 are respectively fixed to the corresponding upper anti-wear component 52 and the lower anti-wear component 54, so the upper anti-wear component 52 and the lower anti-wear component 54 will be in The corresponding upper positioning members 51 and lower positioning members 53 rotate continuously, and the presence of the rubber ring 523 will reduce the rigid contact area inside the upper positioning members 51 and the lower positioning members 53, thereby reducing the wear between the upper anti-wear component 52, the lower anti-wear component 54 and the corresponding upper positioning members 51 and the lower positioning members 53 to a certain extent. At the same time, the presence of the liquid flow will remove the heat generated by friction and the wear products that may be generated, thereby reducing the heat energy and wear products caused by friction inside the upper positioning members 51 and the lower positioning members 53, and further extending the service life of the upper anti-wear component 52 and the lower anti-wear component 54 in the corresponding upper positioning members 51 and the lower positioning members 53. In this way, this design alleviates the wear phenomenon to a certain extent, and then ensures the controllability of the axial offset of the rotating shaft 31 to a certain extent.

[0070] It should be noted that the specific models and specifications of the lifting member 21, the cup lid clamping member 22, the lifting cylinder 232, the elastic member 235, the motor 32, the pulley assembly 321, the upper telescopic member 42, the lower telescopic member 43 and the joint 412 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0071] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
