Description

Technical Field

[0001] This invention relates to the field of ceramic cutting technology, and in particular to a handheld industrial ceramic cutting device. Background Technology

[0002] Industrial ceramics include ordinary ceramics, alumina ceramics, and silicon carbide ceramics. Alumina, as a commonly used industrial ceramic material, is widely used in many industries. Alumina tubes and rods possess excellent electrical insulation, high chemical resistance, and low thermal expansion. A common cutting method involves fixing one side of the tube or rod and then cutting the other end using a cutting assembly. This results in uneven stress during the cutting process, easily leading to uneven cuts and chipping of the square tube. Chinese utility model patent CN218694476U discloses a stable alumina square tube cutting device. While this prior art fixes the workpiece on both sides, solving the problem of uneven stress during cutting, it is inconvenient to carry, and the clamping method is cumbersome, requiring manual adjustment bit by bit, which is time-consuming and has low production efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a handheld industrial ceramic cutting device, comprising a handheld outer shell, the outer shell including a base plate, a cutting device mounted on the outer shell, the outer shell being used by a user for cutting operations, the cutting device including a cutting motor fixedly mounted on the base plate, the cutting device being used to cut industrial ceramic products, a clamping device on the outer shell including a clamping frame fixedly mounted on the base plate, the clamping device being used to clamp the industrial ceramic product to be cut, and an unlocking device on the outer shell including a side rail fixedly mounted on the base plate, the unlocking device being used to release the clamping device from the industrial ceramic product.

[0004] Manually pull open the unlocking device, then place the industrial ceramic product in the clamping device, clamp the industrial ceramic product with the clamping device, and cut the industrial ceramic product with the cutting device by holding the outer shell device.

[0005] Furthermore, the outer casing device includes an outer casing fixed to a base plate, a top cover fixedly installed on the outer casing, a handle fixedly installed on the top cover, and a protective cover rotatably installed on the handle.

[0006] The user holds the handle and uses the cutting device to cut the industrial ceramic products on the clamping device. During cutting, the protective cover is manually rotated along the top cover to protect the area around the industrial ceramic products and prevent ceramic slag from flying and injuring people.

[0007] Furthermore, the cutting device includes a motor bevel gear fixedly mounted on the motor shaft of the cutting motor, a gear stand and a stand fixedly mounted on the base plate, a drive wheel rotatably mounted on the gear stand, a vertical bevel gear fixedly mounted on the drive wheel, the motor bevel gear meshing with the vertical bevel gear, two driven wheel frames slidably mounted on the stand, a compression spring provided between the two driven wheel frames, driven wheels rotatably mounted on the driven wheel frames, a lower guide rail fixedly mounted on the base plate, a guide rail groove provided on the lower guide rail, an upper guide rail fixedly mounted on the bottom of the upper cover, and a feeding mechanism provided on the upper cover.

[0008] Furthermore, the feeding mechanism includes a connecting pipe fixedly installed on the upper cover, a lead screw slidably installed on the connecting pipe, a movable frame slidably installed on the lead screw, a pusher frame fixedly installed on the movable frame, a rotating shaft rotatably installed on the pusher frame, a cutting blade and a cutting pulley fixedly installed on the rotating shaft, a roller rotatably installed outside the rotating shaft, the rollers rollingly installed with the guide rail groove, a transmission belt wrapped around the cutting pulley, driven wheel, and driving wheel, the pusher frame slidably installed with the upper guide rail, and a rotating ring mechanism provided on the lead screw.

[0009] Furthermore, the rotating ring mechanism includes a manual rotating ring rotatably mounted outside the lead screw. The manual rotating ring has an internal thread, and the manual rotating ring and the lead screw form a threaded transmission through the internal thread. A pull pin is slidably mounted inside the manual rotating ring, and a return spring is provided between the pull pin and the manual rotating ring. The pull pin is slidably mounted with the thread groove of the lead screw.

[0010] During operation, the cutting motor rotates, driving the motor bevel gear, which in turn drives the vertical bevel gear and the drive wheel. This, in turn, drives the cutting pulley via the transmission belt, which in turn drives the cutting blade. Simultaneously, the manual rotating ring is turned by hand, causing it to rotate along the thread of the lead screw and advance. This causes the moving frame to slide on the lead screw, which in turn causes the push frame to slide forward along the upper guide rail. This causes the roller to roll forward in the guide rail groove, and the cutting blade to advance along the lower guide rail. The cutting blade cuts the industrial ceramic products on the clamping device. During the cutting process, as the cutting pulley moves outward, the driven wheel frame slides in the vertical frame, and the compression spring is compressed, keeping the transmission belt taut. After cutting, the pull pin is manually lifted along the manual rotating ring. The return spring is compressed, causing the pull pin to disengage from the thread groove of the lead screw. At this time, under the rebound action of the compression spring, the push frame slides back along the upper guide rail, and the moving frame slides back along the lead screw, returning to the initial position.

[0011] Furthermore, the clamping device includes a vertical clamping frame fixedly mounted on a clamping frame, the clamping frame having multiple ball grooves, a central turntable rotatably mounted on the vertical clamping frame, an outer turntable fixedly mounted on the central turntable, three protruding pillars circumferentially fixedly mounted on the vertical clamping frame, each protruding pillar having a rotating rod rotatably mounted on it, three rotating sliders circumferentially rotatably mounted on the outer turntable, the rotating rods slidingly mounted to the rotating sliders, clamping wheels rotatably mounted at the ends of the rotating rods, the ceramic workpiece being clamped between the three clamping wheels, a tension spring being provided between the central turntable and the vertical clamping frame, a lower rotating tooth being fixedly mounted at the bottom of the central turntable, and an adjustment mechanism being provided on the clamping frame.

[0012] Furthermore, the adjustment mechanism includes a sliding block slidably mounted on the clamping frame, a limit plate fixedly mounted on the sliding block, a pop-out ball slidably mounted on the side of the sliding block, and a pop-out spring provided between the pop-out ball and the sliding block.

[0013] When the outer turntable rotates clockwise along the vertical clamping frame, it causes the rotating rod to rotate relative to the vertical clamping frame, and the rotating slider to rotate relative to the outer turntable. The rotating rod and the rotating slider slide relative to each other, and at this time, the clamping wheel will move away from the outer wall of the ceramic workpiece, and the clamping will be released. When the outer turntable rotates counterclockwise along the vertical clamping frame, it causes the rotating rod to rotate relative to the vertical clamping frame, and the rotating slider to rotate relative to the outer turntable. The rotating rod and the rotating slider slide relative to each other, and at this time, the clamping wheel will press against the outer wall of the ceramic workpiece, and the ceramic workpiece will be clamped.

[0014] In the initial state, the tension spring is in a stretched state, which has a pre-tightening force that pulls the turntable to rotate counterclockwise along the vertical clamping frame. The clamping wheel holds the ceramic workpiece. When the ceramic workpiece needs to be removed after cutting, the unlocking mechanism causes the outer turntable to rotate clockwise, and the clamping wheel leaves the ceramic workpiece, at which point the ceramic workpiece can be taken out.

[0015] During installation, one end of the ceramic workpiece rests against the limiting plate. The cutting length of the ceramic workpiece is adjusted by manually adjusting the distance between the limiting plate and the cutting blade. The limiting plate and the sliding block can slide within the clamping frame.

[0016] The clamping frame is equipped with multiple ball grooves, which cooperate with the pop-out balls in the sliding block. Through the cooperation between the pop-out balls and the ball grooves, combined with the elastic force of the pop-out spring, the limiting plate remains in a fixed position when not manually pulled.

[0017] Furthermore, the unlocking device includes a sliding bar with a fixed sliding column inside the side track, a rack frame fixedly installed on the sliding bar, a bottom column slidably installed on the rack frame, a rack fixedly installed on the bottom column, the rack meshing with a lower rotating tooth, a downward pressure spring provided between the bottom column and the rack frame, a pulling frame fixedly installed on the rack frame, a pulling plate fixedly installed on the pulling frame, and the pulling plate slidably installed with the base plate.

[0018] Since the clamping device is in a clamping state by default, the clamping state needs to be released before placing the ceramic workpiece between the clamping wheels. Manually pull the pull plate, which in turn pulls the pull frame. The pull frame pulls the rack frame to slide within the side track. The rack engages with the lower rotating tooth, causing the outer turntable to rotate clockwise. The tension spring is further stretched. At this point, place the ceramic workpiece between the clamping wheels, ensuring its end rests against the limit plate. Then push the pull plate, which in turn pushes the rack frame to slide within the side track. The rack drives the lower rotating tooth to rotate counterclockwise, coordinating with the pull... The spring returns and clamps the ceramic workpiece through the clamping wheel. At this point, since the ceramic workpiece may be relatively thick, if the pull plate is pushed further, the rack and pinion will slide along the side rail. The rack can no longer drive the lower rotating tooth to engage because the clamping wheel has clamped it to the tightest position. The central turntable can no longer rotate. If the pull plate is pushed further, the bottom column and rack will slide down along the rack and pinion, and the lower spring will be stretched. When the rack passes the lower rotating tooth, the lower spring returns to its initial state, allowing the rack to return to its initial position through the lower rotating tooth.

[0019] The beneficial effects of the present invention compared with the prior art are: (1) The shell device of the present invention is provided with a protective cover, so that when the cutting device cuts industrial ceramic products, ceramic powder is prevented from splashing out and causing personal injury; (2) The clamping device of the present invention automatically clamps by elastic force. When it is necessary to remove the industrial ceramic products, the unlocking device can be unlocked by manually pulling the unlocking device. The clamping and unlocking methods are quick and convenient; (3) The cutting device of the present invention drives the cutting blade to cut industrial ceramic products by manually rotating and manually switching. The cutting device can be quickly reset by pulling the pull pin, which is convenient to use. Attached Figure Description

Detailed Implementation

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0037] Example: Reference Figures 1-15 A handheld industrial ceramic cutting device includes a handheld outer shell. The outer shell includes a base plate 101, and a cutting device is mounted on it. The outer shell is used by a user to perform cutting operations. The cutting device includes a cutting motor 201, which is fixedly mounted on the base plate 101. The cutting device is used to cut industrial ceramic products. A clamping device is also provided on the outer shell, including a clamping frame 301, which is fixedly mounted on the base plate 101. The clamping device is used to clamp the industrial ceramic product to be cut. An unlocking device is also provided on the outer shell, including a side rail 401, which is fixedly mounted on the base plate 101. The unlocking device is used to release the clamping device from the industrial ceramic product.

[0038] Manually pull open the unlocking device, then place the industrial ceramic product in the clamping device, clamp the industrial ceramic product with the clamping device, and cut the industrial ceramic product with the cutting device by holding the outer shell device.

[0039] like Figures 1-3 As shown, the housing device includes a housing 102 fixed on a base plate 101, a top cover 103 fixedly mounted on the housing 102, a handle 104 fixedly mounted on the top cover 103, and a protective cover 105 rotatably mounted on the handle 104.

[0040] The user holds the handle 104 and uses the cutting device to cut the industrial ceramic product on the clamping device. During cutting, the protective cover 105 is manually rotated along the upper cover 103 to protect the industrial ceramic product and prevent ceramic slag from flying and injuring people.

[0041] like Figures 4-9 As shown, the cutting device includes a motor bevel gear 202 fixedly mounted on the motor shaft of the cutting motor 201. A gear stand 203 and a stand 209 are fixedly mounted on the base plate 101. A drive wheel 205 is rotatably mounted on the gear stand 203. A vertical bevel gear 204 is fixedly mounted on the drive wheel 205. The motor bevel gear 202 meshes with the vertical bevel gear 204. Two driven wheel frames 220 are slidably mounted on the stand 209. A compression spring 208 is provided between the two driven wheel frames 220. A driven wheel 207 is rotatably mounted on the driven wheel frame 220. A lower guide rail 210 is fixedly mounted on the base plate 101. A guide rail groove 2101 is provided on the lower guide rail 210. An upper guide rail 214 is fixedly mounted on the bottom of the upper cover 103. A feeding mechanism is provided on the upper cover 103.

[0042] like Figures 4-8As shown, the feeding mechanism includes a connecting pipe 218 fixedly mounted on the upper cover 103, a lead screw 215 slidably mounted on the connecting pipe 218, a movable frame 216 slidably mounted on the lead screw 215, a pusher frame 213 fixedly mounted on the movable frame 216, a rotating shaft 223 rotatably mounted on the pusher frame 213, a cutting blade 212 and a cutting pulley 211 fixedly mounted on the rotating shaft 223, a roller 222 rotatably mounted outside the rotating shaft 223, the roller 222 rollingly mounted with the guide rail groove 2101, a transmission belt 206 wrapped around the cutting pulley 211, the driven wheel 207, and the driving wheel 205, the pusher frame 213 slidably mounted with the upper guide rail 214, and a rotating ring mechanism provided on the lead screw 215.

[0043] like Figure 8 , Figure 9 As shown, the rotating mechanism includes a manual rotating ring 217 rotatably mounted outside the lead screw 215. The manual rotating ring 217 has an internal thread 2171. The manual rotating ring 217 and the lead screw 215 form a threaded transmission through the internal thread 2171. A pull pin 219 is slidably mounted inside the manual rotating ring 217. A return spring 221 is provided between the pull pin 219 and the manual rotating ring 217. The pull pin 219 is slidably mounted to the threaded groove of the lead screw 215.

[0044] During operation, the cutting motor 201 rotates, driving the motor bevel gear 202 to rotate, which in turn drives the vertical bevel gear 204 and the drive wheel 205 to rotate. This, in turn, drives the cutting pulley 211 to rotate via the transmission belt 206, thereby driving the cutting disc 212 to rotate. Simultaneously, the manual rotating ring 217 is turned by hand, causing it to rotate forward along the thread of the lead screw 215. This causes the moving frame 216 to slide on the lead screw 215, which in turn causes the pusher frame 213 to slide forward along the upper guide rail 214. This causes the roller 222 to roll forward in the guide rail groove 2101, allowing the cutting disc 212 to advance along the lower guide rail 210, thus cutting the disc. The blade 212 cuts the industrial ceramic product on the clamping device. During the cutting process, as the cutting pulley 211 moves outward, the driven wheel frame 220 slides in the upright frame 209. The compression spring 208 is compressed, keeping the transmission belt 206 taut. After the cutting is completed, the pull pin 219 is manually lifted along the manual rotating ring 217. The return spring 221 is compressed, causing the pull pin 219 to disengage from the thread groove of the lead screw 215. At this time, under the rebound action of the compression spring 208, the push frame 213 slides back along the upper guide rail 214, and the moving frame 216 slides back along the lead screw 215, returning to the initial position.

[0045] like Figures 10-13As shown, the clamping device includes a vertical clamping frame 302 fixedly mounted on a clamping frame 301. The clamping frame 301 is provided with multiple ball grooves 3011. A central turntable 303 is rotatably mounted on the vertical clamping frame 302. An outer turntable 304 is fixedly mounted on the central turntable 303. Three protruding pillars 307 are fixedly mounted circumferentially on the vertical clamping frame 302. A rotating rod 308 is rotatably mounted on each of the protruding pillars 307. Three rotating sliders 309 are rotatably mounted circumferentially on the outer turntable 304. The rotating rods 308 and the rotating sliders 309 are slidably mounted. A clamping wheel 310 is rotatably mounted at the end of the rotating rod 308. The ceramic workpiece 311 is clamped between the three clamping wheels 310. A tension spring 305 is provided between the central turntable 303 and the vertical clamping frame 302. A lower rotating tooth 306 is fixedly mounted at the bottom of the central turntable 303. An adjustment mechanism is provided on the clamping frame 301.

[0046] like Figure 12 , Figure 13 As shown, the adjustment mechanism includes a sliding block 313 slidably mounted on the clamping frame 301, a limit plate 312 fixedly mounted on the sliding block 313, a pop-out ball 315 slidably mounted on the side of the sliding block 313, and a pop-out spring 314 provided between the pop-out ball 315 and the sliding block 313.

[0047] When the outer turntable 304 rotates clockwise along the vertical clamping frame 302, it will cause the rotating rod 308 to rotate relative to the vertical clamping frame 302, and the rotating slider 309 to rotate relative to the outer turntable 304. The rotating rod 308 and the rotating slider 309 slide relative to each other. At this time, the clamping wheel 310 will move away from the outer wall of the ceramic workpiece 311, and the clamping will be released. When the outer turntable 304 rotates counterclockwise along the vertical clamping frame 302, it will cause the rotating rod 308 to rotate relative to the vertical clamping frame 302, and the rotating slider 309 to rotate relative to the outer turntable 304. The rotating rod 308 and the rotating slider 309 slide relative to each other. At this time, the clamping wheel 310 will press against the outer wall of the ceramic workpiece 311, and the ceramic workpiece 311 will be clamped.

[0048] In the initial state, the tension spring 305 is in a stretched state, and it has a pre-tightening force that pulls the turntable 303 to rotate counterclockwise along the vertical clamping frame 302. The clamping wheel 310 clamps the ceramic workpiece 311. When the ceramic workpiece 311 needs to be removed after cutting, the outer turntable 304 is rotated clockwise by the unlocking mechanism, and the clamping wheel 310 leaves the ceramic workpiece 311. At this time, the ceramic workpiece 311 can be taken out.

[0049] During installation, one end of the ceramic workpiece 311 presses against the limiting plate 312. The cutting length of the ceramic workpiece 311 is adjusted by manually adjusting the distance between the limiting plate 312 and the cutting blade 212. The limiting plate 312 and the sliding block 313 can slide within the clamping frame 301. The clamping frame 301 is provided with multiple ball grooves 3011, which cooperate with the pop-out ball 315 in the sliding block 313. Through the cooperation between the pop-out ball 315 and the ball groove 3011, combined with the elastic force of the pop-out spring 314, the limiting plate 312 remains unchanged in position without being manually pulled.

[0050] like Figure 14 , Figure 15 As shown, the unlocking device includes a sliding bar 408 with a fixed sliding column inside the side rail 401, a rack frame 404 fixedly mounted on the sliding bar 408, a bottom column 406 slidably mounted on the rack frame 404, a rack 405 fixedly mounted on the bottom column 406, the rack 405 meshing with the lower rotating tooth 306, a downward pressure spring 407 between the bottom column 406 and the rack frame 404, a pulling frame 403 fixedly mounted on the rack frame 404, a pulling plate 402 fixedly mounted on the pulling frame 403, and the pulling plate 402 slidably mounted on the base plate 101.

[0051] Since the clamping device is in a clamping state by default, the clamping state needs to be released before placing the ceramic workpiece 311 between the clamping wheels 310. Manually pull the pull plate 402, which in turn pulls the pull frame 403. The pull frame 403 pulls the rack frame 404 to slide within the side rail 401. The rack 405 meshes with the lower rotating tooth 306, causing the outer turntable 304 to rotate clockwise. The tension spring 305 is further stretched. At this point, the ceramic workpiece 311 is placed between the clamping wheels 310, with its end touching the limit plate 312. Then, push the pull plate 402, which in turn pushes the rack frame 404 to slide within the side rail 401. The rack 405 drives the lower rotating tooth 306 to rotate counterclockwise, coordinating with the tension spring. The rebound of 305 clamps the ceramic workpiece 311 through the clamping wheel 310. At this time, since the ceramic workpiece 311 may be relatively thick, if the pull plate 402 is pushed further, the rack frame 404 will slide along the side rail 401. The rack 405 can no longer drive the lower rotating tooth 306 to engage because the clamping wheel 310 has already clamped to the tightest position. The central turntable 303 can no longer rotate. If the pull plate 402 is pushed further, the bottom column 406 and the rack 405 will slide down along the rack frame 404. The lower pressure spring 407 will be stretched. When the rack 405 passes the lower rotating tooth 306, the lower pressure spring 407 will rebound and return to the initial state, so that the rack 405 can return to the initial position through the lower rotating tooth 306.

[0052] The working principle of the handheld industrial ceramic cutting device disclosed in this invention is as follows: First, the cutting length of the ceramic workpiece 311 is adjusted by manually adjusting the distance between the limiting plate 312 and the cutting blade 212. The limiting plate 312 and the sliding block 313 can slide within the clamping frame 301. The clamping frame 301 is provided with multiple ball grooves 3011, which cooperate with the pop-out ball 315 in the sliding block 313. Through the cooperation between the pop-out ball 315 and the ball groove 3011, combined with the elastic force of the pop-out spring 314, the limiting plate 312 remains unchanged in position without being manually pulled. Manually pull the pull plate 402, thereby pulling the pull frame 403. The pull frame 403 pulls the rack frame 404 to slide within the side rail 401. The rack 405 meshes with the lower rotating tooth 306, causing the outer turntable 304 to rotate clockwise. The tension spring 305 is further stretched. At this time, the ceramic workpiece 311 is placed between the clamping wheels 310, with its end abutting against the limit plate 312. Then, push the pull plate 402, thereby pushing the rack frame 404 to slide within the side rail 401. The rack 405 drives the lower rotating tooth 306 counterclockwise. The needle rotates, coordinating with the rebound of the tension spring 305. The tension spring 305 retains its elasticity after rebounding, clamping the ceramic workpiece 311 via the clamping wheel 310. The protective cover 105 is manually rotated to enclose the clamping device, protecting the industrial ceramic product from flying ceramic slag and preventing injury. The user holds the handle 104. The cutting motor 201 rotates, driving the motor bevel gear 202, which in turn drives the vertical bevel gear 204 and the drive wheel 205, which in turn drive the cutting pulley 211 via the transmission belt 206. This drives the cutting blade 212 to rotate. Simultaneously, the manual rotating ring 217 is manually rotated, causing it to advance along the thread of the lead screw 215. This drives the moving frame 216 to slide on the lead screw 215, which in turn drives the pushing frame 213 to slide forward along the upper guide rail 214. This causes the roller 222 to roll forward in the guide rail groove 2101, allowing the cutting blade 212 to advance along the lower guide rail 210. The cutting blade 212 cuts the industrial ceramic products on the clamping device. During the cutting process, the cutting pulley... 211 moves outward, and the driven wheel frame 220 slides in the upright frame 209. The compression spring 208 is compressed, keeping the transmission belt 206 taut. After cutting, the pull pin 219 is manually lifted along the manual rotating ring 217. The return spring 221 is compressed, causing the pull pin 219 to disengage from the threaded groove of the lead screw 215. At this time, under the rebound action of the compression spring 208, the push frame 213 slides back along the upper guide rail 214, and the moving frame 216 slides back along the lead screw 215, returning to the initial position. When the ceramic workpiece 311 needs to be removed after cutting, the outer turntable 304 is rotated clockwise by the unlocking mechanism, and the clamping wheel 310 leaves the ceramic workpiece 311, at which point the ceramic workpiece 311 can be removed.
