Description

Technical Field

[0001] This invention relates to the field of ceramic fixture processing technology, and more specifically to a positioning device for ceramic fixture processing. Background Technology

[0002] Ceramic processing refers to the specialized processing of ceramics in a workshop. Any object made from clay (either earthenware or porcelain clay) through processes such as batching, shaping, drying, and firing can be called ceramic. Ceramic processing requires specialized tools and techniques. The processing of ceramic materials is a special case of machining; general machining workshops do not possess the capability for ceramic processing.

[0003] During the processing of ceramic fixtures, in order to ensure their stability and facilitate the processing operations of workers, positioning devices are needed to clamp and fix the ceramic fixtures. However, most of the current positioning devices clamp and fix the ceramic fixtures mechanically, which often requires workers to manually lift the ceramic plates and fix them, which is quite laborious and inconvenient for workers to operate.

[0004] The prior art has a kind of Figure 3 The ceramic mounting bracket 100 shown has corresponding weight-reducing grooves on both its transverse and longitudinal sides. During the processing of the ceramic mounting bracket 100, it is necessary to accurately position the ceramic mounting bracket 100 to ensure the accuracy of the processing position. Errors in the processing position will cause the product to fail to meet customer requirements.

[0005] Chinese patent (CN219171326U) discloses a processing positioning device such as Figure 7 As shown, a support platform is used for support, and then both ends are fixed and clamped. However, when clamping the ceramic fixture 100, the device cannot perform precise positioning and clamping. Furthermore, during the processing, the contact between the processing device and the ceramic fixture 100 causes the ceramic fixture 100 to easily deflect slightly, resulting in a shift in the processing position and insufficient processing accuracy. Summary of the Invention

[0006] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a positioning device for processing ceramic fixing brackets.

[0007] The objective of this invention can be achieved through the following technical solutions:

A rotating component one is provided inside the clamping and positioning base assembly. A combination mechanism is connected to the rotating component one. A rotating component two is provided inside the clamping and positioning base assembly and outside the rotating component one. When the combination mechanism is de-energized, the rotating component one and the rotating component two are connected. A clamping mechanism is symmetrically provided on the rotating component two.

[0009] The combined mechanism includes a synchronization plate installed on the rotating component. The top edge of the synchronization plate has symmetrical positioning grooves on both sides. An electromagnet and a positioning spring are connected in the positioning groove. A connecting pin is connected to the top of the positioning spring. An electric control module is provided on the top surface of the synchronization plate. The electric control module is electrically connected to the electromagnet.

[0011] As a further embodiment of the present invention: the rotating assembly includes a rotating motor installed inside the mounting slot. The output shaft of the rotating motor is connected to a rotating platform. A fixing slot is provided in the middle of the top of the rotating platform. An electric telescopic rod is fixedly installed in the fixing slot. The telescopic end of the electric telescopic rod is connected to a bearing platform. Multiple transverse locking bases are symmetrically arranged on both sides of the bearing platform. A sliding groove is provided inside the transverse locking base. Two locking springs with opposite directions of movement are fixed in the middle of the sliding groove. The other end of the locking spring is connected to a locking post. A variable diameter sleeve is provided on the locking post extending outward.

[0012] As a further embodiment of the present invention: the rotating assembly 2 includes multiple guide rods connected in the slide rail groove, the top of the multiple guide rods are connected to a rotating connecting plate, the rotating connecting plate has a through groove in the middle, the top edge of the rotating connecting plate is symmetrically connected to connecting blocks, the two connecting blocks are connected to rotating bases, and the bottom of the rotating connecting plate has a connecting groove for connecting with the combined mechanism.

[0013] As a further aspect of the present invention: the clamping mechanism includes a clamping base, a movable motor is mounted on one side of the clamping base, and a movable screw is rotatably mounted inside the clamping base. The output shaft of the movable motor is connected to the movable screw, and a vertical moving rod is threaded onto the movable screw. A clamping component is connected to the inner side of the vertical moving rod.

[0014] As a further embodiment of the present invention: the clamping assembly includes a vertical motion base, a double-section screw is rotatably connected inside the vertical motion base, the two ends of the double-section screw are symmetrically connected to mating clamps, a positioning clamp is installed in the middle of the double-section screw, a motion motor is provided at the top of the vertical motion base, and the output shaft of the motion motor is connected to the double-section screw.

Furthermore, clamping mechanisms are symmetrically arranged on rotating component two. The two clamping mechanisms can accurately position and clamp the ceramic fixture, and at the same time drive the ceramic fixture to rotate for processing position calibration.

[0018] This invention provides multiple locking posts 1 and 2. Moving locking post 1 can change the position of the corresponding locking post 1, thereby laterally positioning and clamping the ceramic fixing frame with the weight reduction groove located at different positions. Pulling the pull rod can cause locking post 2 to slide, thereby fixing the weight reduction groove of the ceramic fixing frame in the longitudinal direction. By fixing in both the lateral and longitudinal directions, it avoids the occurrence of lateral or longitudinal displacement during processing, which would affect the processing accuracy.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The prior art has a kind of Figure 3 The ceramic mounting bracket 100 shown has corresponding weight-reducing grooves on both its transverse and longitudinal sides. During the processing of this ceramic mounting bracket 100, precise positioning is required to ensure accuracy. Errors in the positioning will result in the product failing to meet customer requirements. Existing processing positioning devices, such as... Figure 7 As shown, a support platform is used for support, and then both ends are fixed and clamped. However, when clamping the ceramic fixture 100, the device cannot perform precise positioning and clamping. Furthermore, during the processing, the contact between the processing device and the ceramic fixture 100 causes the ceramic fixture 100 to easily deflect slightly, resulting in a shift in the processing position and insufficient processing accuracy.

[0030] Therefore, as Figures 1-6As shown, a positioning device for processing ceramic fixtures is used to position the aforementioned ceramic fixture 100. The device includes a clamping and positioning base assembly 1 mounted on a corresponding processing machine. A rotating component 2 is disposed inside the clamping and positioning base assembly 1. A combination mechanism 3 is connected to the rotating component 2. A rotating component 4 is disposed inside the clamping and positioning base assembly 1 and outside the rotating component 2. The combination mechanism 3 can connect the rotating component 2 and the rotating component 4, allowing the rotating component 4 to rotate around a center line. Furthermore, clamping mechanisms 5 are symmetrically disposed on the rotating component 4. The two clamping mechanisms 5 accurately position and clamp the ceramic fixture 100, and can also drive the ceramic fixture 100 to rotate for processing position calibration.

[0031] Further, such as Figure 1 and Figure 2 As shown, the clamping and positioning base assembly 1 includes a base body 10, an installation cavity 11 is provided inside the base body 10, an installation groove 12 is provided in the middle of the bottom surface of the installation cavity 11 for installation with the rotation motor 21 of the rotation assembly 2, a circular slide rail groove 13 is provided in the bottom surface of the installation cavity 11, and the slide rail groove 13 has an inverted T-shaped cross section, which cooperates with the guide rod 42 of the rotation assembly 4 to guide the rotation, and a through mating groove 14 is provided in the top surface of the installation cavity 11 to facilitate assembly and processing, and a mesh plate 15 is provided on the outside of the base body 10 to facilitate observation and maintenance.

[0032] Further, such as Figure 2 and Figure 3 As shown, the aforementioned rotating assembly 2 includes a rotating motor 21 installed inside the mounting slot 12. The output shaft of the rotating motor 21 is connected to a rotating platform 22, which is T-shaped. A fixing slot is provided in the middle of the top of the rotating platform 22, and an electric telescopic rod 23 is fixedly installed in the fixing slot. The telescopic end of the electric telescopic rod 23 is connected to a support platform 24. Due to the size and shape of the ceramic mounting bracket 100, the support platform 24 is rectangular and shorter than the length of the ceramic mounting bracket 100. Multiple transverse locking bases 25 are symmetrically arranged on both sides of the support platform 24. A sliding mechanism is provided inside the transverse locking base 25. The device has two locking springs 27 with opposite directions of movement fixed in the middle of the sliding groove. The other end of the locking springs 27 is connected to a locking post 26, which is 7-shaped. The locking post 26 extending outward is fitted with a variable diameter sleeve 28. The variable diameter sleeve 28 can be replaced according to the size of the weight reduction groove of the ceramic fixing frame 100. At the same time, the top of the locking post 26 also has a transverse through groove on the top surface of the transverse locking base 25. By moving the locking post 26, the position of the corresponding locking post 26 can be changed, and the ceramic fixing frame 100 with the weight reduction groove in different positions can be laterally positioned and clamped, so that the device can be used for different products.

[0033] Further, such as Figure 2 As shown, the aforementioned rotating assembly 4 includes multiple guide rods 42 connected in the slide rail groove 13. The top of the multiple guide rods 42 is connected to a rotating connecting plate 41. The rotating connecting plate 41 has a through groove in the middle, which is not open to the rotating table 22 and does not affect the movement. Connecting blocks 43 are symmetrically connected at the top edge of the rotating connecting plate 41. A rotating base 44 is connected to the two connecting blocks 43. A ball bearing (not shown in the figure) is provided between the outer side of the rotating base 44 and the mating groove 14 to reduce the friction of the movement. The rotating base 44 has a ring structure, and two symmetrical clamping mechanisms 5 are provided on the top surface of the rotating base 44.

[0034] Furthermore, in order to synchronously drive the rotating component 24 to move, such as Figure 2 The assembly shown includes a combination mechanism 3, which includes a synchronous plate 31 connected to the output shaft of the rotating motor 21. Positioning slots are symmetrically formed on both sides of the top edge of the synchronous plate 31. An electromagnet 34 is connected to the bottom of each positioning slot, and a positioning spring is also connected to the slot. A connecting pin 33 is connected to the top of the positioning spring. An electrical control module 32 is also provided at a corresponding position on the top surface of the synchronous plate 31. The electrical control module 32 is electrically connected to the electromagnet 34 and controls the energization of the electromagnet 34. Furthermore, a connecting slot is formed at the bottom of the rotating connecting plate 41 corresponding to the position of the connecting pin 33. When the rotating component 2 4 needs to rotate, the electrical control module 32 de-energizes the electromagnet 34, causing the connecting pin 33 to rise under the elastic force of the positioning spring and engage with the connecting slot, thus achieving the connection between the rotating component 1 2 and the rotating component 2 4.

[0035] Further, such as Figure 2 , Figures 4 to 6As shown, the clamping mechanism 5 includes a clamping base 51 fixed to the top surface of the rotating base 44. A moving motor is installed on one side of the clamping base 51, and a moving screw is rotatably installed inside the clamping base 51. The output shaft of the moving motor is connected to the moving screw. A vertical moving rod 52 is threaded onto the moving screw. A clamping assembly 53 is connected to the inner side of the vertical moving rod 52. The clamping assembly 53 includes a vertical moving base 531 fixedly connected to the vertical moving rod 52. A double-section screw is rotatably connected inside the vertical moving base 531. Matching clamps 533 are symmetrically connected to both ends of the double-section screw, and a positioning clamp 534 is installed in the middle of the double-section screw. The positioning clamp 534 is rotatably connected to the double-section screw and fixedly connected to the vertical moving base 531. A moving motor 532 is provided at the top of the vertical moving base 531. The output shaft of 532 is connected to a double-section screw. Further, the positioning clamp 534 has two vertically penetrating inclined slots 535, symmetrically arranged. The inclined slots 535 are inclined outwards. A second locking post 536 is slidably installed in the inclined slot 535. A pull rod 538 is located in the middle of the second locking post 536, extending outwards from the movement slots on both sides of the positioning clamp 534. A second locking spring 537 connects the second locking post 536 and the inclined slot 535. Pulling the pull rod 538 causes the second locking post 536 to slide, thereby fixing the longitudinal weight-reducing slot of the ceramic fixing bracket 100. This fixation in both the transverse and longitudinal directions prevents lateral or longitudinal offset during processing, thus avoiding impact on processing accuracy. A variable diameter sleeve 539 is fitted on the outer side of the second locking post 536, which is also replaceable according to the corresponding weight-reducing slot size.

[0036] In operation, the ceramic fixing frame 100 is placed on the support platform 24, and the positions of multiple locking posts 26 are adjusted to fix the ceramic fixing frame 100 horizontally. Then, the electric telescopic rod 23 is activated to drive the ceramic fixing frame 100 to correspond with the two clamping mechanisms 5. The two moving motors are activated to drive the two clamping components 53 to move inward until the ceramic fixing frame 100 is connected with the longitudinal locking post 536. Then, the motion motor 532 is activated to drive the two mating clamping plates 533 to move and fix the ceramic fixing frame 100 vertically. Then, the electric telescopic rod 23 is activated to retract, releasing the ceramic fixing frame 100 from the support platform 24, completing the clamping and processing.

[0037] When rotation is required to correct the machining position, the electronic control module 32 controls the electromagnet 34 to de-energize, so that the connecting pin 33 connects to the rotating connecting plate 41 under the action of elastic force. Then, the rotating motor 21 is started, which drives the rotating table 22 and the synchronous plate 31 to rotate synchronously. The synchronous plate 31 drives the rotating connecting plate 41 to rotate synchronously, and the rotating connecting plate 41 drives the rotating base 44 to rotate, which in turn drives the two clamping mechanisms 5 to rotate. The two clamping mechanisms 5 drive the clamped ceramic fixing frame 100 to rotate and correct the machining position. The reason for driving the bearing table 24 to move synchronously is to ensure that the clamping position of the bearing table 24 always corresponds with the two clamping mechanisms 5, ensuring the convenience of the next clamping and avoiding angular deflection, which would prevent longitudinal clamping from being performed.

[0038] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
