Description

Technical Field

[0001] This invention relates to the field of ceramic processing equipment technology, and in particular to a clamping fixture for processing ceramics. Background Technology

[0002] Ceramics is a general term for pottery and porcelain. Any object made from clay and porcelain clay, two types of clay with different properties, through processes such as batching, shaping, drying, and firing can be called ceramics. Processing ceramic products requires special processing tools and techniques. In order to facilitate the operation of operators, tooling fixtures are often used to clamp and fix the ceramics to ensure the stability and accuracy of the processing.

[0003] However, existing ceramic tooling fixtures have many unsolvable defects: firstly, manual operation is cumbersome and laborious, resulting in low processing efficiency; secondly, the stability of clamping round ceramics is poor, and it is not easy to prevent slipping; thirdly, the bottom is not convenient to provide flexible support, which affects the stability of clamping.

[0004] Therefore, a new clamping fixture for ceramic processing is proposed to solve the problems of existing ceramic clamping fixtures, such as cumbersome operation, poor coordination between clamping and support, insufficient operational safety, limited adaptability, and easy breakage due to vibration during ceramic processing. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping fixture for processing ceramics, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A clamping fixture for processing ceramics includes a control component, a clamping component, and a support component. The clamping component is provided on one side of the control component, and the support component is provided below the clamping component. The three components work together to achieve stable clamping, flexible adjustment, and safe support of ceramics, adapting to the processing and clamping needs of round ceramics of different sizes. The control assembly includes a handle, an extension bracket, a secondary handle, a first control button, and a second control button. The extension bracket is fixedly installed on the outer wall of the handle, and the secondary handle is installed on the bottom of the extension bracket near the handle, forming a two-hand gripping operating structure. The first control button and the second control button are respectively located on the top of the extension bracket near the operating handle and are symmetrically distributed; The extension bracket is equipped with a controller. The first control button is electrically connected to the first motor and the second motor, and the second control button is electrically connected to the electric cylinder. The system employs a linkage control method where a single press of the first control button controls the rotation of the first motor, and a double press controls the rotation of the second motor. This is combined with a safety distance design for the extension bracket and a dual-grip structure.

[0007] Preferably, the clamping assembly includes a clamping ring, an anti-slip inner pad, a connecting shaft, a lead screw, a lead screw nut, a connecting bracket, a fixing ring, a limiting ring, a limiting protrusion, a movable slot, a fixed slot, and a mounting side plate. The clamping ring is semi-circular, with two clamping rings symmetrically distributed and one slidingly disposed on the other side. The two rings together form a circular clamping space adapted to the circular ceramic. The anti-slip inner pad fixed to the inner wall of the clamping ring is uniformly provided with circular protrusions.

[0008] Preferably, one of the connecting pins is connected to the sliding side clamping ring and slides in the movable slot of the extension bracket, and the other connecting pin is connected to the fixed side clamping ring and fixed in the fixed slot of the extension bracket; the limiting ring is engaged with the outside of the sliding side connecting pin, and the limiting protrusion on its outer wall is adapted to engage with the limiting grooves at the top and bottom of the movable slot.

[0009] Preferably, the mounting side plate is fixed to both sides of the bottom of the extension bracket, the lead screw is rotatably connected to the inner wall of the mounting side plate, the first motor drive end is connected to the lead screw, the lead screw nut is threaded on the outside of the lead screw, the bottom end of the connecting bracket is connected to the lead screw nut, and the top end is engaged with the fixed retaining ring on the sliding side connecting shaft to form an electric adjustment structure for the clamping distance.

[0010] Preferably, the support assembly includes an L-shaped support bracket, a second motor, a telescopic support rod, a movable locking hole, a support base plate, a lifting support plate, a damper, a shock-absorbing spring, and an electric cylinder. The support bracket is fixedly installed at the bottom of the operating handle to achieve a stable connection with the control assembly.

[0011] Preferably, the second motor is fixed to the bottom of the support bracket, and its drive end is connected to the bottom end of the telescopic support rod. The movable locking hole at the bottom of the support bracket is adapted to the bottom of the telescopic support rod to ensure that the telescopic support rod rotates and extends smoothly. The support base plate is fixed to the top of the telescopic support rod, and its shape is adapted to the shape of the clamping ring to directly support the bottom of the ceramic.

[0012] Preferably, the lifting support plate is movably connected to the bottom of the supporting base plate, and its movable locking hole is adapted to the top of the telescopic support rod; Electric cylinders are symmetrically arranged on both sides of the telescopic support rod. Their bottom ends are connected to the top of the support bracket, and their top ends are connected to the bottom of the lifting support plate, driving the lifting support plate and the support base plate to rise and adjust.

[0013] Preferably, the damper is located between the lifting support plate and the support bracket, with its top end connected to the four bottom corners of the lifting support plate and its bottom end connected to the top of the support bracket. The damping spring is movably sleeved outside the damper, with its top end connected to the four bottom corners of the lifting support plate and its bottom end connected to the top of the support bracket. The damper and the damping spring work together to buffer and reduce shock.

[0014] Preferably, both the movable card slot and the fixed card slot have wear-resistant linings on their walls, and the wear-resistant linings are made of polytetrafluoroethylene.

[0015] Preferably, the extension bracket is made of lightweight aluminum alloy, and the outer wall of the extension bracket is provided with an anti-slip grip layer.

[0016] The beneficial effects of this invention are as follows: This invention uses a single first control button to distinguish control commands based on the number of times it is pressed. A single press controls the first motor to drive the clamping ring to adjust the spacing, while two presses control the second motor to drive the support base plate to rotate. In conjunction with symmetrically arranged second control buttons, the electric cylinder can be independently controlled to achieve support height adjustment. This completely solves the problem that traditional ceramic clamping fixtures require multiple independent buttons to operate the clamping, lifting, and rotating components, resulting in cumbersome operation and confusing commands.

[0017] Meanwhile, the control unit is equipped with a dual grip structure of a main handle and a secondary handle, allowing operators to hold it stably with both hands. Combined with the safe operating distance formed by the extended support, it enables the entire process of clamping, adjusting, and picking up materials to be completed with one hand, greatly reducing the difficulty of operation and improving the overall efficiency of processing and clamping.

[0018] The clamping assembly features a double semi-circular ring-shaped clamping ring design, combined with an inner anti-slip pad and circular protrusions to effectively increase friction with the ceramic surface, preventing the ceramic from sliding or falling off during processing. Simultaneously, the electric drive structure via a lead screw, lead nut, and motor enables precise and automatic adjustment of the clamping ring spacing, adapting to the clamping needs of round ceramics of different diameters, offering exceptional versatility. Furthermore, the connecting shaft of the sliding-side clamping ring is guided by the engagement of a limiting protrusion and a limiting groove, ensuring smooth and offset movement during clamping adjustment, further improving clamping accuracy and stability, and ensuring accurate positioning during ceramic processing.

[0019] An electric cylinder drives the support plate to precisely fit the bottom of the ceramic, achieving omnidirectional support and adaptation with the clamping components. This overcomes the limitations of traditional tooling, which can only clamp a single component and cannot provide precise support. A second motor drives the telescopic support rod and the support plate to rotate, allowing for flexible adjustment of the processing angle according to the ceramic processing requirements, meeting multi-directional processing needs. Simultaneously, the synergistic cooperation of the damper and shock-absorbing spring effectively absorbs vibrations generated during processing, preventing vibration from being transmitted to the ceramic body. This fundamentally solves the technical problem of ceramics being easily damaged by vibration, ensuring the safety and stability of the processing. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Reference Figures 1-6A clamping fixture for processing ceramics includes a control component 1, a clamping component 2, and a support component 3. The clamping component 2 is provided on one side of the control component 1, and the support component 3 is provided below the clamping component 2. The three components work together to achieve stable clamping, flexible adjustment, and safe support of ceramics, and are suitable for the processing and clamping requirements of round ceramics.

[0024] The control component 1 includes a handle 11, an extension bracket 12, a secondary handle 13, a first control button 14, and a second control button 15. The extension bracket 12 is fixedly installed on the outer wall of the handle 11, and the secondary handle 13 is installed on the extension bracket 12 near the bottom of the handle 11, which facilitates the operator's two-hand grip and improves operational stability. The first control button 14 and the second control button 15 are respectively located on the top of the extension bracket 12 near the handle 11, and the two are symmetrically distributed, which facilitates the operator's quick operation and precise control. The support bracket 301 is fixedly installed on the bottom of the handle 11, and the support bracket 301 is L-shaped, realizing a stable connection between the support component 3 and the control component 1.

[0025] The extension bracket 12 is equipped with a controller. The first control button 14 is electrically connected to the first motor 34 and the second motor 302, and the second control button 15 is electrically connected to the electric cylinder 309. The control buttons enable precise control of each actuator. Pressing the first control button 14 once controls the first motor 34 to rotate, and pressing the first control button 14 twice controls the second motor 302 to rotate.

[0026] The clamping assembly 2 includes a clamping ring 21, an anti-slip inner pad 22, a connecting shaft 23, a lead screw 30, a lead screw nut 31, a connecting bracket 32, a fixing ring 33, a limiting ring 26, a limiting protrusion 27, a moving slot 24, a fixed slot 25, and a mounting side plate 29. The components work together to achieve stable clamping and flexible adjustment of the ceramic.

[0027] The clamping ring 21 is semi-circular in shape, with two clamping rings 21 symmetrically distributed. One clamping ring 21 is slidably disposed on one side of the other clamping ring 21, and the two together form a circular clamping space, which is suitable for clamping circular ceramics. The anti-slip inner pad 22 is fixedly installed on the inner wall of the clamping ring 21, and the inner wall of the anti-slip inner pad 22 is evenly provided with circular protrusions, which can effectively improve the friction between the clamping surface and the ceramic surface, enhance the clamping adhesion, and prevent the ceramic from sliding or falling off during processing.

[0028] The connecting shaft 23 is disposed on one side of the clamping ring 21 and is used to connect the clamping ring 21 to other components. The fixing ring 33 is annular and is engaged with the connecting shaft 23 of one of the clamping rings 21 to achieve linkage between the connecting bracket 32 ​​and the clamping ring 21. The side wall of the extension bracket 12 is provided with a movable slot 24 and a fixing slot 25. The fixing slot 25 is disposed on one side of the movable slot 24. One connecting shaft 23 is slidably connected to the inner wall of the movable slot 24 and can slide back and forth along the movable slot 24. The other connecting shaft 23 is fixedly installed on the inner wall of the fixing slot 25 to fix the clamping ring 21 on one side.

[0029] The limiting ring 26 is circular and is engaged with the outside of the sliding connecting shaft 23. The outer wall of the limiting ring 26 is symmetrically provided with limiting protrusions 27. The top and bottom of the movable slot 24 are symmetrically provided with limiting grooves 28 that are adapted to the limiting protrusions 27. The limiting protrusions 27 are embedded in the limiting grooves 28, which can effectively improve the stability of the connecting shaft 23 in the movable slot 24, avoid deviation during movement, and ensure the accuracy of clamping and adjustment.

[0030] The mounting side plate 29 is fixedly installed on both sides of the bottom of the extension bracket 12 for fixing the lead screw 30 and the first motor 34. The two ends of the lead screw 30 are respectively rotatably connected to the inner walls of the two sides of the mounting side plate 29 to ensure that the lead screw 30 rotates smoothly. The first motor 34 is fixedly installed on the mounting side plate 29, and its driving end is fixedly connected to one end of the lead screw 30 to provide power for the rotation of the lead screw 30. The lead screw nut 31 is threadedly connected to the outside of the lead screw 30. The bottom end of the connecting bracket 32 ​​is fixedly connected to the outer wall of the lead screw nut 31, and the top end of the connecting bracket 32 ​​is fixedly connected to the fixing ring 33 to form a linkage structure.

[0031] The working principle of the clamping assembly 2 is as follows: After the first motor 34 starts, it drives the lead screw 30 to rotate. When the lead screw 30 rotates, it drives the lead screw nut 31 to move along the axial direction of the lead screw 30. The lead screw nut 31 drives the fixed retaining ring 33 to move synchronously through the connecting bracket 32. The fixed retaining ring 33 drives the connecting retaining shaft 23 connected to it to slide along the moving retaining groove 24, thereby driving the clamping retaining ring 21 on one side to move, realizing the flexible adjustment of the distance between the two clamping retaining rings 21, so as to firmly clamp and limit the circular ceramics of different sizes.

[0032] The supporting assembly 3 includes a supporting bracket 301, a second motor 302, a telescopic support rod 303, a movable locking hole 304, a supporting base plate 305, a lifting support plate 306, a damper 307, a shock-absorbing spring 308, and an electric cylinder 309. The components work together to provide stable support for the clamped ceramic, and also have shock absorption, lifting, and rotation adjustment functions.

[0033] The support bracket 301 is L-shaped and fixedly installed at the bottom of the operating handle 11 for fixing the second motor 302, electric cylinder 309, and damper 307. The second motor 302 is fixedly installed at the bottom of the support bracket 301, and its drive end is fixedly connected to the bottom end of the telescopic support rod 303 to provide power for the rotation of the telescopic support rod 303. The bottom of the support bracket 301 is provided with a movable locking hole 304, and the bottom of the telescopic support rod 303 is fixedly installed on the inner wall of the movable locking hole 304 that matches it, to ensure that the telescopic support rod 303 rotates and extends smoothly. The support base plate 305 is fixedly installed at the top of the telescopic support rod 303 to directly support the bottom of the ceramic. Its shape matches the encircling shape of the clamping ring 21 to improve the support fit.

[0034] The lifting support plate 306 is movably connected to the bottom of the supporting base plate 305. The lifting support plate 306 is also provided with a movable locking hole 304. The top of the telescopic support rod 303 passes through the movable locking hole 304 of the lifting support plate 306, ensuring that the telescopic support rod 303 can rise and fall synchronously with the lifting support plate 306 without affecting the rotation of the telescopic support rod 303. The electric cylinder 309 is symmetrically arranged on both sides of the telescopic support rod 303. Its bottom end is fixedly set on the top of the supporting bracket 301, and its top end is fixedly set on the bottom of the lifting support plate 306. It is used to drive the lifting support plate 306 to rise and fall, thereby driving the supporting base plate 305 to rise and fall and adjust.

[0035] The damper 307 is disposed between the lifting support plate 306 and the support bracket 301. Its top end is fixedly disposed at the bottom four corners of the lifting support plate 306, and its bottom end is fixedly disposed at the top of the support bracket 301. The shock-absorbing spring 308 is movably sleeved on the outside of the damper 307. Its top end is connected to the bottom four corners of the lifting support plate 306, and its bottom end is connected to the top of the support bracket 301. The damper 307 and the shock-absorbing spring 308 work together to effectively buffer and absorb the vibration received by the support base plate 305, prevent the vibration from being transmitted to the ceramic, prevent the ceramic from being damaged due to vibration, and improve the support stability.

[0036] The working principle of the support component 3 is as follows: After the second motor 302 starts, it drives the telescopic support rod 303 to rotate, which in turn drives the support base plate 305 to rotate synchronously. The support angle can be adjusted according to the ceramic processing requirements. After the ceramic is clamped, the electric cylinder 309 is extended and retracted by the second control button 15. The electric cylinder 309 drives the lifting support plate 306 to rise and fall. The telescopic support rod 303 extends and retracts with the rise and fall of the lifting support plate 306, which in turn drives the support base plate 305 to rise and fall, so that the support base plate 305 is precisely attached to the bottom of the ceramic, providing stable support for the ceramic and helping to improve the clamping stability. The vibration generated during the processing is transmitted to the lifting support plate 306 through the support base plate 305. It is initially buffered by the shock-absorbing spring 308 and further absorbed by the damper 307 to ensure a smooth support process.

[0037] In some preferred embodiments, the walls of both the movable card slot 24 and the fixed card slot 25 are provided with wear-resistant linings, and the wear-resistant linings are made of polytetrafluoroethylene.

[0038] In some preferred embodiments, the extension bracket 12 is made of lightweight aluminum alloy, and the outer wall of the extension bracket 12 is provided with an anti-slip grip layer.

[0039] Workflow: 1. Operation preparation: The operator holds the control handle 11 with one hand and the auxiliary handle 13 with the other hand, and lifts up the entire device. The extension bracket 12 can maintain a safe operating distance between the operator and the clamping component 2 and the support component 3 to avoid injury during processing. 2. Clamping Adjustment: Pressing the first control button 14 once starts the first motor 34, which drives the lead screw 30 to rotate. The lead screw nut 31 moves along the lead screw 30, and through the connecting bracket 32 ​​and the fixing ring 33, it drives the clamping ring 21 on one side to move. Adjust the distance between the two clamping rings 21, place the round ceramic between the two clamping rings 21, and then operate the first control button 14 in reverse to make the two clamping rings 21 close. The anti-slip inner pad 22 achieves stable clamping of the ceramic. The limiting ring 26 ensures a smooth clamping adjustment process through the cooperation of the limiting protrusion 27 and the limiting groove 28. 3. Support Adjustment: The electric cylinder 309 is extended and retracted by the second control button 15, which drives the lifting support plate 306, the telescopic support rod 303 and the support base plate 305 to rise and fall, so that the support base plate 305 is attached to the bottom of the ceramic to complete the support; if it is necessary to adjust the ceramic processing angle, press the first control button 14 twice to start the second motor 302, which drives the telescopic support rod 303, the support base plate 305 and the ceramic to rotate synchronously and adjust to the required angle; 4. Processing completed: After the ceramic processing is completed, press the first control button 14 once to control the first motor 34 to rotate in the opposite direction, so that the two clamping rings 21 separate, release the ceramic, and the material can be picked up. The operation is convenient and efficient.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
