Description

Technical Field

[0001] This invention relates to the field of trimming machine technology, and more specifically, to a trimming machine for sanitary ceramics. Background Technology

[0002] A blank trimming machine is a specialized piece of equipment used to finish wet or semi-dry blanks after ceramic products are formed and before firing. Its main function is to remove excess clay, trim the shape, polish the surface, open holes or chamfer the blank by rotating the blank and using cutting tools (such as scrapers and milling cutters), so that the blank can achieve the dimensional accuracy, wall thickness uniformity and surface smoothness required by the design.

[0003] In the process of trimming bathroom ceramic blanks, the blanks are usually in a wet or semi-dry state, and their texture is fragile. Traditional clamps are difficult to secure reliably. If mechanical clamping is used alone, the blank is prone to deformation or cracking due to uneven pressure. Without bottom support, the blank is prone to slippage, eccentricity or even flying off due to centrifugal force or cutting force of the tool during high-speed rotation trimming, resulting in scrap or safety accidents. On the other hand, vacuum adsorption alone is difficult to adapt to complex curved surfaces or blanks with high air permeability, and the adsorption force is insufficient. With the increasing demand for customized and high-precision ceramic products, how to achieve non-destructive, stable and rapid clamping of irregular wet blanks through multi-level collaborative fixing method - combining circumferential clamping, bottom vacuum adsorption and upper adaptive pressing - has become a key technical challenge to improve trimming efficiency, yield and equipment automation level. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a sanitary ceramic trimming machine that can quickly fix the blank material during trimming.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A bathroom ceramic trimming machine includes a base, a turntable rotatably connected to the upper surface of the base, a fixed column fixedly mounted on the upper surface of the turntable, a support platform fixedly mounted on the upper end of the fixed column, a placement plate fixedly mounted on the upper surface of the support platform, a fixing mechanism on the upper side of the placement plate, the fixing mechanism including a clamping assembly disposed on the lower side of the placement plate, the clamping assembly including a transmission disc rotatably connected to the outer surface of the fixed column, a worm gear fixedly mounted on the lower surface of the transmission disc, a worm engaging on one side of the worm gear, a handle fixedly mounted on one end of the worm, the worm being rotatably connected to the turntable, a transmission groove formed on the upper surface of the transmission disc, a sliding groove formed on the upper surface of the support platform, a sliding rod slidably connected inside the sliding groove, the sliding rod passing through the transmission groove and extending to the upper side of the placement plate, the sliding rod being slidably connected to the transmission groove.

[0007] A crossbar is fixedly installed at the upper end of the slide bar, and a sponge block is fixedly installed on the inner side of the crossbar. The transmission groove, slide groove, slide bar, crossbar and sponge block are all provided in four sets and are arranged in a ring.

[0008] The installation mechanism also includes an adsorption component disposed inside the support platform. The adsorption component includes rectangular blocks fixedly installed at both ends of a crossbar. A transmission frame is sleeved on the outside of the rectangular blocks, and the transmission frame is slidably connected to the rectangular blocks.

[0009] A spring and an airbag are fixedly installed inside the transmission frame. The other end of the spring and the airbag are fixedly connected to a rectangular block. The spring is located on the outside of the rectangular block, and the airbag is located on the inside of the rectangular block. A sponge block is fixedly installed at one end of the transmission frame.

[0010] The fixed column has a piston chamber 1 and a piston chamber 2 inside. The piston chamber 1 is located below the piston chamber 2. A connecting pipe is provided between the piston chamber 1 and the airbag.

[0011] A piston plate is slidably connected inside the piston chamber one, and a piston plate is slidably connected inside the piston chamber two. A connecting post is fixedly installed on the upper end face of the piston plate one, and the upper end of the connecting post extends into the interior of the piston chamber two and is fixedly connected to the piston plate two. A groove is provided on the upper end face of the placement plate.

[0012] The fixing mechanism also includes an adjustment assembly disposed on the upper side of the crossbar. The adjustment assembly includes a support member fixedly installed on the upper end face of the crossbar. A rotating rod is rotatably connected to the end of the support member. A coil spring is fixedly installed at one end of the rotating rod, and one end of the coil spring is fixedly connected to the crossbar.

[0013] A sleeve is fixedly installed on the outer surface of the rotating rod, and a bolt is screwed onto the outer surface of the sleeve. A vertical rod is slidably connected to the upper end of the sleeve, and a sponge block is fixedly installed at the end of the vertical rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] (1) This solution uses a multi-level fixing mechanism to stably clamp the semi-dry ceramic blank. The clamping component provides preliminary circumferential positioning, and the bottom adsorption component uses vacuum negative pressure to firmly hold the blank from the bottom to prevent slippage during rotation. The adjustment component can move up and down and adaptively apply auxiliary clamping force to the upper contour of the blank. The three work together to effectively avoid the blank from loosening, shifting or falling off due to centrifugal force or tool cutting during the blank repair process, thereby improving the processing accuracy and yield. It is suitable for efficient repair operations of complex sanitary ceramic parts such as irregular shapes and thin walls. Attached Figure Description

[0028] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 5A bathroom ceramic trimming machine includes a base 1, a turntable 2 rotatably connected to the upper surface of the base 1, a fixed column 3 fixedly installed on the upper surface of the turntable 2, a support platform 4 fixedly installed on the upper end of the fixed column 3, a placement plate 5 fixedly installed on the upper surface of the support platform 4, a fixing mechanism on the upper side of the placement plate 5, the fixing mechanism including a clamping assembly disposed on the lower side of the placement plate, the clamping assembly including a transmission plate 6 rotatably connected to the outer surface of the fixed column 3, a worm gear 7 fixedly installed on the lower surface of the transmission plate 6, a worm 8 meshing on one side of the worm gear 7, a handle 9 fixedly installed at one end of the worm 8, the worm 8 being rotatably connected to the turntable 2, a transmission groove 10 opened on the upper surface of the transmission plate 6, a sliding groove 11 opened on the upper surface of the support platform 4, a sliding rod 12 slidably connected inside the sliding groove 11, the sliding rod 12 passing through the transmission groove 10 and extending to the upper side of the placement plate, the sliding rod 12 being slidably connected to the transmission groove 10.

[0030] A crossbar 13 is fixedly installed at the upper end of the slide bar 12, and a sponge block 14 is fixedly installed on the inner side of the crossbar 13. The transmission groove 10, the slide groove 11, the slide bar 12, the crossbar 13 and the sponge block 14 are all provided in four sets and are arranged in a ring.

[0031] Turntable 2 is driven to rotate by an external motor, and works with the blank trimming equipment to trim the blank. First, the blank is placed in the groove 23 on the placement table. Then, according to the height of the blank, the height of the vertical rod 32 is adjusted. The bolt 31 is loosened, and the vertical rod 32 can be pulled out from the sleeve 30. After adjusting to an appropriate height, the bolt 31 is tightened again to fix the vertical rod 32. Then, the handle 9 on the worm gear 8 can be turned to make the worm gear 8 rotate. The worm gear 8 meshes with the worm wheel 7 on the transmission disc 6, so the transmission disc 6 will rotate with the rotation of the worm gear 8. A transmission groove 10 is provided, and a sliding rod 12, which is slidably connected inside the sliding groove 11, is also slidably connected to the transmission groove 10. Therefore, under the drive of the transmission disc 6, the sliding rod 12 can move towards the blank in conjunction with the action of the transmission groove 10 and the sliding groove 11, and simultaneously carry the crossbar 13 and the sponge block 14 on the crossbar 13 towards the blank. The four sets of sponge blocks 14 move towards the blank simultaneously, thereby clamping and fixing the blank. After selecting an appropriate clamping force, the rotation of the worm 8 can be stopped. The transmission between the worm 8 and the worm wheel 7 has self-locking properties, which can maintain the current fixed state.

[0032] The installation mechanism also includes an adsorption component set inside the support 4. The adsorption component includes a rectangular block 15 fixedly installed at both ends of the crossbar 13. A transmission frame 16 is sleeved on the outside of the rectangular block 15, and the transmission frame 16 is slidably connected to the rectangular block 15.

[0033] A spring 17 and an airbag 19 are fixedly installed inside the transmission frame 16. The other ends of the spring 17 and the airbag 19 are fixedly connected to the rectangular block 15. The spring 17 is located on the outside of the rectangular block 15, and the airbag 19 is located on the inside of the rectangular block 15. A sponge block 18 is fixedly installed on one end of the transmission frame 16.

[0034] The fixed column 3 has a piston chamber 21 and a piston chamber 24 inside. The piston chamber 21 is located on the lower side of the piston chamber 24. A connecting pipe 20 is provided between the piston chamber 21 and the airbag 19.

[0035] Piston plate 22 is slidably connected inside piston chamber 1 21, piston plate 25 is slidably connected inside piston chamber 24, a connecting post 26 is fixedly installed on the upper end face of piston plate 1 22, the upper end of the connecting post 26 extends into the interior of piston chamber 24 and is fixedly connected to piston plate 25, and a groove 23 is provided on the upper end face of the placement plate 5.

[0036] Secondly, when the crossbar 13 moves toward the blank, the sponge block 18 on the transmission frame 16 will simultaneously adhere to the blank. As the crossbar 13 continues to move, it will exert a reverse action on the transmission frame 16, thereby squeezing the airbag 19. This causes the gas inside the airbag 19 to enter the piston chamber 21 through the connecting pipe 20, causing the piston plate 22, which is slidably connected inside the piston chamber 21, to descend. The piston plate 22 and the piston plate 25 are fixedly connected by the connecting column 26. Therefore, the piston plate 25 will descend inside the piston chamber 24, performing vacuum adsorption on the bottom of the blank and improving stability.

[0037] The fixing mechanism also includes an adjustment assembly disposed on the upper side of the crossbar 13. The adjustment assembly includes a support member 27 fixedly installed on the upper end face of the crossbar 13. A rotating rod 28 is rotatably connected to the end of the support member 27. A coil spring 29 is fixedly installed at one end of the rotating rod 28. One end of the coil spring 29 is fixedly connected to the crossbar 13.

[0038] A sleeve 30 is fixedly installed on the outer surface of the rotating rod 28. A bolt 31 is screwed on the outer surface of the sleeve 30. A vertical rod 32 is slidably connected to the upper end of the sleeve 30. A sponge block 33 is fixedly installed at the end of the vertical rod 32.

[0039] Meanwhile, the sponge block 33 on the vertical rod 32 is in close contact with the blank. The sleeve 30 at the lower end of the vertical rod 32 is fixedly connected to the rotating rod 28. A coil spring 29 is fixedly installed at one end of the rotating rod 28. Under the action of the elastic deformation of the coil spring 29, the sponge block 33 is in close contact with the blank, providing auxiliary support and fixation for the upper part of the blank.

[0040] In the process of trimming bathroom ceramic blanks, the blanks are usually in a wet, soft, or semi-dry state, making them fragile. Traditional clamps are difficult to use for reliable fixation. If only mechanical clamping is used, uneven pressure can easily cause deformation or cracking of the blank. Without bottom support, during high-speed rotation trimming, the blank is prone to slippage, eccentricity, or even flying off due to centrifugal force or cutting force, resulting in scrap or safety accidents. On the other hand, vacuum adsorption alone is difficult to adapt to complex curved surfaces or highly permeable blanks, as the adsorption force is insufficient. With the increasing demand for customized, high-precision ceramic products, how can a multi-level synergistic fixing method—combining circumferential clamping, bottom vacuum adsorption, and upper adaptive pressing—be used to effectively fix irregularly shaped wet blanks? Non-destructive, stable, and rapid clamping has become a key technical challenge in improving the efficiency, yield, and automation level of ceramic blanks. Therefore, this solution uses a multi-stage fixing mechanism to stably clamp semi-dry ceramic blanks. The clamping component provides initial circumferential positioning, the bottom adsorption component uses vacuum negative pressure to firmly hold the blank from below, preventing slippage during rotation, and the adjustment component can move up and down to adaptively apply auxiliary clamping force to the upper contour of the blank. The three work together to effectively avoid the blank from loosening, shifting, or falling off due to centrifugal force or tool cutting during the blanking process, thereby improving processing accuracy and yield. It is suitable for efficient finishing operations of complex sanitary ceramic parts such as irregular shapes and thin walls.

[0041] Instructions for use: The turntable 2 is driven to rotate by an external motor. It is used in conjunction with the blank trimming equipment for blank trimming. First, place the blank in the groove 23 on the placement table. Then, adjust the height of the vertical rod 32 according to the height of the blank. Loosen the bolt 31 to pull the vertical rod 32 out of the sleeve 30. After adjusting to the appropriate height, tighten the bolt 31 again to fix the vertical rod 32. Then, twist the handle 9 on the worm gear 8 to rotate the worm gear 8. The worm gear 8 meshes with the worm wheel 7 on the transmission disc 6, so the transmission disc 6 will rotate with the rotation of the worm gear 8, thus transmitting power. The disk 6 has a transmission groove 10, and the slide rod 12, which is slidably connected inside the slide groove 11, is also slidably connected to the transmission groove 10. Therefore, under the drive of the transmission disk 6, the slide rod 12 can move towards the blank in conjunction with the action of the transmission groove 10 and the slide groove 11, and simultaneously carry the crossbar 13 and the sponge block 14 on the crossbar 13 towards the blank. The four sets of sponge blocks 14 move towards the blank simultaneously, thereby clamping and fixing the blank. After selecting an appropriate clamping force, the rotation of the worm 8 can be stopped. The transmission between the worm 8 and the worm wheel 7 has self-locking properties, which can maintain the current fixed state.

[0042] Secondly, when the crossbar 13 moves toward the blank, the sponge block 18 on the transmission frame 16 will simultaneously adhere to the blank. As the crossbar 13 continues to move, it will exert a reverse action on the transmission frame 16, thereby squeezing the airbag 19. This will cause the gas inside the airbag 19 to enter the piston chamber 21 through the connecting pipe 20, causing the piston plate 22, which is slidably connected inside the piston chamber 21, to descend. The piston plate 22 and the piston plate 25 are fixedly connected by the connecting column 26. Therefore, the piston plate 25 will descend inside the piston chamber 24, performing vacuum adsorption on the bottom of the blank and improving stability.

[0043] Meanwhile, the sponge block 33 on the vertical rod 32 is in close contact with the blank. The sleeve 30 at the lower end of the vertical rod 32 is fixedly connected to the rotating rod 28. A coil spring 29 is fixedly installed at one end of the rotating rod 28. Under the action of the elastic deformation of the coil spring 29, the sponge block 33 is in close contact with the blank, providing auxiliary support and fixation for the upper part of the blank.

[0044] The above description is merely a preferred embodiment of the present invention; however, 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 its improved concepts, should be covered within the scope of protection of the present invention.
