Detailed implementation manners

[0038] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] See Figures 1 to 14As shown, a stainless steel elbow tee cutting device that is easy to clamp quickly includes a vertical frame 1, a fixed column 2, an adjustment mechanism 3 and an avoidance mechanism 4; a fixed column 2 is arranged on one side of the top of the vertical frame 1, and a plurality of strip grooves 21 are arranged circumferentially on the outer wall of the fixed column 2, and a strip slide rail 22 is slidably arranged in each strip groove 21, and two moving blocks 23 are slidably arranged inside each strip slide rail 22, and two adjacent moving blocks 23 are hinged on the opposite sides thereof with hinge plates 231, and the two hinge plates 231 located in the same strip groove 21 are hinged to each other, and an arc-shaped contact plate 232 is arranged at the hinge of each two adjacent hinge plates 231; the adjustment mechanism 3 is arranged on the fixed column 2, and the fixed column 2 is provided with a plurality of strip grooves 21 on the outer wall of ... inner wall of the fixed column 2, and the fixed column 2 is provided with a plurality of strip grooves 21 on the inner The fixed column 2 can make the two moving blocks 23 in the multiple strip slides 22 approach synchronously; a rotating ring 11 is also rotatably arranged on the vertical frame 1, and the rotating ring 11 is coaxially arranged with the fixed column 2. A mounting rod 12 is also arranged at the edge of the rotating ring 11, and a horizontal plate 13 is arranged at the end of the mounting rod 12 away from the rotating ring 11. A hydraulic rod 14 is arranged on the horizontal plate 13, and the driving direction of the hydraulic rod 14 is toward the axis of the fixed column 2. The actuator of the hydraulic rod 14 passes through the horizontal plate 13 and is provided with a cutting head 15; the avoidance mechanism 4 is arranged on the fixed column 2 and can make the multiple strip slides 22 move back and forth along the corresponding strip grooves 21 in sequence as the rotating ring 11 rotates.

[0040] The staff puts the elbow and the tee on the fixed column 2, and moves the cutting position to the bottom of the cutting head 15. Then, the two moving blocks 23 in the multiple strip slides 22 are brought close to each other by adjusting the mechanism 3. At this time, as the two moving blocks 23 are brought close to each other, the hinged positions of the two hinged plates 231 can move in the direction close to and away from the fixed column 2, so that the corresponding arc-shaped contact plates 232 can fit with the inner walls of the corresponding elbows and tees. The arc-shaped contact plates 232 arranged along the circumference of the fixed column 2 can fix elbows and tees of different specifications at multiple points, so that the cutting position of the elbows and tees is coaxially arranged with the fixed column 2, thereby ensuring the stability during the cutting process of the elbows and tees; then, the cutting head 15 is moved in the direction close to the elbows and tees by adjusting the hydraulic rod 14, so as to cut the elbows and tees; because the cutting head 15 and the multiple arc-shaped contact plates 232 are in the same vertical plane, and the arc-shaped contact plate 232 can support the inner wall of the elbow and the tee during the cutting process, thereby avoiding deformation of the elbow and the tee; secondly, during the cutting process, the cutting head 15 needs to pass through the elbow and the tee to cut the elbow and the tee, and the arc-shaped contact plate 232 will contact the cutting head 15 during the cutting process, thereby affecting the cutting process. Based on this case, by providing an avoidance mechanism 4, a plurality of strip slide rails 22 can move back and forth along the corresponding strip grooves 21 in sequence with the rotation of the rotating ring 11, so that during the annular cutting process of the cutting head 15, the arc-shaped contact plate 232 can move in sequence toward the direction away from the inner wall of the elbow and the tee, thereby avoiding affecting the cutting process of the cutting head 15, and the strip slide rails 22 that move in sequence can ensure the stability of the elbow and the tee, thereby ensuring the quality of cutting.

[0041] It is particularly noted that the facing sides in the present invention are the sides that are close to each other.

[0042] See also Figures 5 to 6 As shown, the avoidance mechanism 4 includes a rotating disk 41, a connecting gear 42 and a synchronous gear 43; a circular groove 24 for accommodating the rotating disk 41 is provided at the center of the fixed column 2, and the rotating disk 41 is rotatably arranged in the circular groove 24, and a guide column 221 extending into the circular groove 24 is provided at the center of one side of each strip-shaped slide rail 22 close to the bottom inner wall of the corresponding strip-shaped groove 21, and the guide column 221 is in conflict with the outer wall of the rotating disk 41, and the outer wall of the rotating disk 41 is provided with a guide column 221 for accommodating the guide column 22 1; a connecting rod 412 is provided at the center of one side of the rotating disk 41 close to the vertical frame 1, and a receiving hole for accommodating the connecting rod 412 is provided on the fixed column 2, and the connecting rod 412 extends out of the receiving hole and is provided with a driven gear 413, and the inner wall of the rotating ring 11 is circumferentially provided with gear teeth 111, and the synchronous gear 43 and the connecting gear 42 are meshed with each other and rotatably arranged on the vertical frame 1, and the synchronous gear 43 is meshed with the gear teeth 111, and the connecting gear 42 is meshed with the driven gear 413.

[0043] The guide post 221 is attached to the outer wall of the rotating disk 41, so that the position of the strip-shaped slide rail 22 can be restricted. With the cooperation of the adjustment mechanism 3, multiple arc-shaped contact plates 232 can be attached to the inner walls of the elbow and the tee. A driving motor for driving the connecting gear 42 to rotate is arranged on the vertical frame 1. The driving motor drives the connecting gear 42 to rotate. The connecting gear 42 drives the rotating ring 11 and the rotating disk 41 to rotate synchronously through the transmission of the synchronous gear 43. During this process, the arc-shaped notch 411 on the rotating disk 41 can rotate synchronously with the cutting head 15, so that the guide post 221 can slide into the arc-shaped notch 411, so that the strip-shaped slide rail 22 at the corresponding position can retract into the strip-shaped groove 21, and the corresponding arc-shaped contact plate 232 can move away from the inner walls of the elbow and the tee, so as to avoid volume collision between the cutting head 15 and the elbow and the tee, and ensure the cutting efficiency of the elbow and the tee.

[0044] See Figures 4 to 9 As shown, the adjustment mechanism 3 includes a main gear 31 and a cross mounting bracket 32; the main gear 31 is coaxially rotatably arranged at one end of the fixed column 2 away from the vertical frame 1. An extension rod 222 is rotatably arranged in each strip-shaped slide rail 22. One end of each extension rod 222 close to the main gear 31 extends out of the fixed column 2 and is provided with a sub-gear 223. The main gear 31 meshes with multiple sub-gears 223; a winding wheel 224 is arranged at the center of each extension rod 222. A longitudinal groove 2211 for avoiding the winding wheel 224 is arranged on each guide post 221. A first traction rope 2241 is wound around each winding wheel 224. A pulling hole is arranged at the center of each strip-shaped slide rail 22. The first traction rope 2241 passes through the pulling hole and is provided with two second traction ropes 2242. Each second traction rope 2242 is connected to the corresponding moving block 23; the cross mounting bracket 32 is arranged on the fixed column 2, and a synchronous motor 33 for driving the main gear 31 is arranged on the cross mounting bracket 32.

[0045] The synchronous motor 33 drives the main gear 31 to rotate. As the main gear 31 rotates, multiple sub-gears 223 are driven to rotate synchronously. Each sub-gear 223 is connected to the corresponding extension rod 222, so that multiple extension rods 222 rotate. The winding wheel 224 on the extension rod 222 can wind the first traction rope 2241. The first traction rope 2241 pulls the corresponding moving blocks 23 to approach each other through two second traction ropes 2242, so that the arc-shaped contact plate 232 arranged between the two hinge plates 231 can contact the inner walls of the elbow and the tee, so as to position and fix the elbow and the tee.

[0046] See Figure 9As shown, two guide plates 225 are provided inside each bar-shaped slide rail 22. A guide hole 2251 for accommodating the second traction rope 2242 is provided on each guide plate 225. A return spring 2243 is also provided on each second traction rope 2242. The return spring 2243 is located between the corresponding guide plate 225 and the moving block 23.

[0047] As the cutting head 15 rotates, the rotating disk 41 can rotate synchronously with the cutting head 15. When the bar-shaped slide rail 22 retracts into the bar-shaped groove 21, the first traction rope 2241 and the second traction rope 2242 are in a loose state. The guide plate 225 can guide the second traction rope 2242 to avoid position deviation. At this time, under the elastic force of the return spring 2243, the two moving blocks 23 can be separated from each other by a certain distance, so that the arc-shaped abutting plate 232 is further separated from the inner walls of the elbow and the tee. Secondly, after cutting is completed, under the elastic force of the return spring 2243, the two moving blocks 23 can be separated from each other, which is convenient for subsequent fixing of the elbow and the tee.

[0048] See Figures 9 to 14As shown, a reinforcement mechanism 5 for secondary fixation of the cutting position is further provided on each arc-shaped contact plate 232; each group of reinforcement mechanisms 5 includes a vertical block 51, a contact plate 52 and a rectangular strip 53; a vertical through groove 2321 is provided at the center of each arc-shaped contact plate 232, the vertical block 51 is slidably arranged in the vertical through groove 2321, hinge grooves 511 are provided on both sides of the end of the vertical block 51 away from the fixed column 2 along the length direction, and a contact plate 52 is hinged in each hinge groove 511; a U-shaped plate 2322 is provided at the bottom of each arc-shaped contact plate 232, a transverse plate 512 is provided at the bottom of the vertical block 51, and the transverse plate 512 and the U-shaped plate 2322 are connected to each other by a protruding spring 513. Installation grooves 521 are provided on the non-adjacent sides of the two contact plates 52, a pulling rope 522 is arranged in the installation groove 521, guiding holes 514 for the pulling rope 522 to pass through are provided on the vertical block 51, and one end of the pulling rope 522 away from the installation groove 521 is arranged on the inner wall of the top of the corresponding U-shaped plate 2322 through the corresponding guiding hole 514; rectangular grooves 2323 are further provided on both sides of the vertical through groove 2321, the opening end of the rectangular through groove faces the arc surface and is communicated with the vertical through groove 2321 through a horizontal groove 2324, a blocking plate 233 is slidably arranged in each horizontal groove 2324, a rectangular through groove is provided at the bottom of each rectangular through groove, a rectangular strip 53 is slidably arranged in each rectangular through groove, a reaction groove 2331 for the rectangular strip 53 to pass through is provided on the blocking plate 233, right trapezoidal blocks 531 matched with the reaction groove 2331 are respectively arranged on both sides of the rectangular strip 53, an installation plate 532 is further provided on the rectangular strip 53, and a pushing spring 533 is sleeved on each rectangular strip 53, and the pushing spring 533 is located between the corresponding installation plate 532 and the inner wall of the bottom of the rectangular groove 2323.

[0049] In order to further ensure the stability between the cut part and the original part during the cutting of elbows and tees, and to avoid deformation at the cutting position, a reinforcement mechanism 5 is provided on the arc-shaped contact plate 232 to perform secondary reinforcement on the cut position. Specifically, when not clamped, the blocking plates approach each other under the elastic force of the pushing spring 533 to limit the position of the vertical block 51 and prevent it from moving out of the vertical through groove 2321; when the arc-shaped contact plate 232 fits against the inner wall of the elbow or tee, the arc-shaped strip can contact the inner wall of the elbow or tee prior to the arc-shaped contact plate 232. At this time, the right-angled trapezoidal block 531 provided on the arc-shaped contact plate 232 can contact the reaction groove 2331 on the blocking plate, causing two adjacent blocking plates to separate from each other. At this time, if this position is not cut, the blocking plate will contact the inner wall under the elastic force of the protruding spring 513 and cannot extend out of the vertical through groove 2321; conversely, when the cutting position is in a state where cutting is completed and a cutting gap is generated, the vertical block 51 can extend out through the cutting gap under the elastic force of the protruding spring 513. At this time, by pulling the pulling rope 522, the two abutting plates 52 rotate along the hinge position, and the abutting plates 52 are respectively attached to both sides of the cutting gap, thereby applying a pressing force to the outside of the elbow or tee, further preventing the cutting position from splitting from the cut position and ensuring stability during the cutting process.

[0050] See Figures 9 to 14 As shown, each abutting plate 52 is hinged in the corresponding hinge groove 511 through the connecting shafts 523 provided on both sides thereof. A ratchet wheel 524 is also provided on each hinge shaft, and a ratchet pawl 515 cooperating with the ratchet wheel 524 is provided on the vertical block 51.

[0051] By providing a ratchet wheel 524 on the connecting shaft 523, the abutting plate 52 can be fixed by the ratchet pawl 515 after rotating to a certain position, thereby preventing the abutting plate 52 from loosening and improving the stability of the abutting plate 52.

[0052] See Figure 2 As shown, a protective cover 16 is also provided on the cutting head 15.

[0053] By providing the protective cover 16, the sparks generated during the cutting process can be blocked, thereby improving safety.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
