Description

Technical Field

[0001] This invention belongs to the field of pipe fitting processing technology, specifically referring to a pipe fitting cutting device. Background Technology

[0002] In the field of pipe processing, the cutting accuracy of pipe fittings directly affects the sealing and stability of pipe connections. Existing pipe fitting cutting devices suffer from the following technical defects:

[0003] 1. Insufficient clamping stability

[0004] Traditional devices often use single-sided or simple symmetrical clamping methods, which have poor adaptability to pipes of different diameters and lengths. Uneven clamping force can easily cause the pipe to shift or shake during the cutting process, affecting the cutting accuracy.

[0005] 2. Lack of internal and external coordination and support

[0006] Most devices only clamp the pipe from the outside. For thin-walled or large-diameter pipe joints, uneven force can easily cause the pipe to deform, making it impossible to guarantee the flatness of the cut surface. Summary of the Invention

[0007] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a pipe joint cutting device, which effectively solves the problems currently on the market.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes a pipe joint cutting device, including a main support assembly for supporting other components and completing the cutting of the workpiece; a transverse support adjustment mechanism, which is disposed on the main support assembly and may include a transverse adjustment mechanism and a ring support mechanism for clamping and fixing the outer side of the pipe; and an adjustable support assembly, which is disposed on the main support assembly for supporting the inner wall of the pipe.

[0009] Furthermore, the lateral adjustment mechanism includes a sliding mounting plate, which is slidably connected to the lateral groove, and the sliding mounting plate is threadedly connected to the lateral screw rod, and the sliding mounting plate is slidably connected to the vertical guide rod; a protective shell is symmetrically arranged on the sliding mounting plate, and the protective shell is detachably connected to the sliding mounting plate.

[0010] Furthermore, the lateral adjustment mechanism also includes a drive motor, which is fixedly mounted on the protective housing; a drive gear, which is fixedly connected to the output end of the drive motor; a support gear, which is positioned symmetrically with the drive gear; and a vertical plate, which is fixedly mounted on the sliding mounting plate, and the support gear is rotatably connected to the vertical plate.

[0011] Furthermore, the annular support mechanism includes an annular mounting bracket mounted on a sliding mounting plate; an adjusting screw that passes through and is threadedly connected to the annular mounting bracket; and a clamping block that is rotatably connected to one end of the adjusting screw.

[0012] Furthermore, the annular support mechanism also includes a mating gear ring, which is fixedly installed on one side of the annular mounting frame and meshes with the drive gear and the support gear; and a connecting ring, which is fixedly installed on the other side of the annular mounting frame and the annular mounting frame is rotatably connected to the sliding mounting plate through the connecting ring.

[0013] Furthermore, the adjustable support assembly includes a fixed rod that passes through and is fixedly connected to the base; a fixed plate that is fixedly connected to one end of the fixed rod; straight grooves that are evenly spaced on the fixed plate; a support ring that is slidably connected to the fixed plate; a connecting bracket that is symmetrically arranged on the fixed rod and is fixedly connected to the fixed rod; and a retaining ring that is fixedly installed on the connecting bracket.

[0014] Furthermore, the adjustable support assembly also includes a rotating disk rotatably connected to the fixed plate; a ratchet rotatably connected to the fixed rod and disposed within a retaining ring; inclined grooves evenly spaced on the rotating disk; a drive block fixedly connected to the ratchet and rotatably connected to the fixed rod for driving the rotating disk to rotate; and a connecting rod fixedly connected to the support ring and slidably connected within the straight groove and the inclined groove.

[0015] Furthermore, the main support assembly includes a base; a transverse slide groove formed on the base; a transverse screw rod disposed in the transverse slide groove, passing through and rotatably connected to the base; a vertical guide rod fixedly installed in the transverse slide groove; a lifting slide groove formed on the base; a vertical screw rod passing through and rotatably connected to the base; a transverse guide rod fixedly disposed on the base; a placement plate threadedly connected to the vertical screw rod and slidably connected to the transverse guide rod; and a cutting assembly fixedly placed on the placement plate.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] (1) The multiple clamping blocks of the ring support mechanism clamp the pipe evenly from the outside, and the support ring of the adjustable support component provides radial support from the inside, forming an internal and external coordinating fixing structure. This effectively avoids the shaking or deformation of the pipe during the cutting process, ensures a flat cutting surface, and improves the processing accuracy of the pipe joint. The horizontal screw drives the sliding mounting plate to move laterally, and the support position can be flexibly adjusted according to the pipe length. The coordinated adjustment of the adjusting screw and the support ring can adapt to pipe joints of different diameters. The vertical screw adjusts the height of the cutting component to meet diverse cutting needs. The overall structure has strong adaptability to different specifications of pipes, reducing the frequency of equipment replacement.

[0018] (2) The drive motor drives the ring mounting bracket and pipe to rotate stably through gear transmission, which facilitates complex processing such as oblique cutting and ring cutting of pipe joints, expanding the applicable scenarios of the device. Each adjustment mechanism achieves precise adjustment through thread transmission, making operation convenient. The protective shell protects the drive components and reduces the risk of mechanical damage. The internal and external collaborative support reduces the debugging time for fixing the pipe and improves the efficiency of batch processing. Attached Figure Description

[0031] like Figures 1-8 As shown.

[0032] In some embodiments, the main support assembly 1 may include a base 101; a transverse slide 102 formed on the base 101; a transverse screw 103 disposed in the transverse slide 102, passing through and rotatably connected to the base 101; a vertical guide rod 104 fixedly installed in the transverse slide 102; a lifting slide 105 formed on the base 101; a vertical screw 106 passing through and rotatably connected to the base 101; a transverse guide rod 107 fixedly disposed on the base 101; a placement plate 108 threadedly connected to the vertical screw 106 and slidably connected to the transverse guide rod 107; and a cutting assembly 109 fixedly placed on the placement plate 108.

[0033] In some embodiments, the lateral support adjustment mechanism 2 may include a lateral adjustment mechanism and an annular support mechanism, wherein the annular support mechanism is disposed on the lateral adjustment mechanism for supporting the workpiece to be cut.

[0034] The lateral adjustment mechanism includes a sliding mounting plate 201, which is slidably connected to a lateral slide groove 102 and threadedly connected to a lateral screw 103, and slidably connected to a vertical guide rod 104; a protective housing 202, symmetrically arranged on the sliding mounting plate 201, and detachably connected to the sliding mounting plate 201; a drive motor 203, fixedly mounted on the protective housing 202; a drive gear 204, fixedly connected to the output end of the drive motor 203; a support gear 205, arranged symmetrically with the drive gear 204; and a vertical plate 206, fixedly mounted on the sliding mounting plate 201, with the support gear 205 rotatably connected to the vertical plate 206.

[0035] The annular support mechanism includes an annular mounting bracket 207, mounted on a sliding mounting plate 201; an adjusting screw 208, which passes through and is threadedly connected to the annular mounting bracket 207; a clamping block 209, rotatably connected to one end of the adjusting screw 208; a mating toothed ring 210, fixedly mounted on one side of the annular mounting bracket 207, and meshing with a drive gear 204 and a support gear 205; and a connecting ring 211, fixedly disposed on the other side of the annular mounting bracket 207, and the annular mounting bracket 207 is rotatably connected to the sliding mounting plate 201 via the connecting ring 211.

[0036] In this embodiment, the position of the sliding mounting plate 201 is adjusted according to the length of the pipe. The operator can manually rotate the transverse screw 103. The rotation of the transverse screw 103 causes the sliding mounting plate 201 to move along the transverse slide groove 102. The sliding mounting plate 201 drives the annular mounting frame 207 to move through the connecting ring 211. After the pipe is placed in the middle position of the annular mounting frame 207, the operator manually rotates the adjusting screw 208. The rotation of the adjusting screw 208 drives the clamping block 209 to move towards the center position of the annular mounting frame 207 until the clamping block 209 clamps and fixes the pipe. When it is necessary to rotate the pipe, the drive motor 203 can be started. After the drive motor 203 is started, it drives the drive gear 204 to rotate. The drive gear 204 drives the annular mounting frame 207 to rotate through the mating gear ring 210, thereby causing the annular mounting frame 207 to drive the pipe to rotate.

[0037] It should be noted that in the lateral adjustment mechanism, the sliding mounting plate 201 is threadedly connected to the lateral screw 103. Combined with the guiding action of the lateral groove 102 and the vertical guide rod 104, the lateral position of the sliding mounting plate 201 can be precisely adjusted by rotating the lateral screw 103, thereby driving the annular support mechanism to move synchronously. This allows for flexible adjustment of the support position according to the pipe length, ensuring stable support for pipes of different lengths and improving the mechanism's adaptability to diverse workpieces. The adjusting screw 208 of the annular support mechanism is threadedly connected to the annular mounting bracket 207. Rotating the adjusting screw 208 pushes the clamping block 209 towards the center, achieving clamping and fixing of the pipe. The cooperation of multiple sets of adjusting screws 208 and clamping blocks 209 can apply uniform clamping force to the pipe from multiple directions, preventing the pipe from shaking or shifting during cutting, providing a stable reference for subsequent cutting and ensuring cutting accuracy.

[0038] In some embodiments, the adjustable support assembly 3 may include a fixed rod 301 that passes through and is fixedly connected to the base 101; a fixed plate 302 that is fixedly connected to one end of the fixed rod 301; straight grooves 303 that are evenly distributed on the fixed plate 302; a support ring 304 that is slidably connected to the fixed plate 302; a connecting bracket 305 that is symmetrically arranged on the fixed rod 301 and is fixedly connected to the fixed rod 301; and a retaining ring 306 that is fixedly installed on the connecting bracket 305. The rotating disk 307 is rotatably connected to the fixed plate 302; the ratchet 308 is rotatably connected to the fixed rod 301 and is located inside the retaining ring 306; the inclined groove 309 is evenly opened on the rotating disk 307; the driving block 310 is fixedly connected to the ratchet 308 and rotatably connected to the fixed rod 301, and is used to drive the rotating disk 307 to rotate; the connecting rod 311 is fixedly connected to the support ring 304 and is slidably connected to the straight groove 303 and the inclined groove 309.

[0039] In this embodiment, the ratchet 308 is rotated by the drive block 310, and the ratchet 308 drives the rotating disk 307 to rotate. The rotating disk 307 drives the connecting rod 311 to slide along the straight groove 303 through the inclined groove 309 opened on the rotating disk 307. The sliding of the connecting rod 311 along the straight groove 303 drives the support ring 304 to move, so that the outer surface of the support ring 304 abuts against the inner surface of the pipe.

[0040] It should be noted that when the rotating disk 307 rotates, the inclined groove 309, through its sliding engagement with the connecting rod 311, drives the connecting rod 311 to slide along the straight groove 303, thereby causing the support ring 304 to move synchronously. Since the straight groove 303 and the inclined groove 309 are evenly distributed, the support ring 304 can synchronously approach or move away from the center from multiple directions, achieving adaptive support for pipe fittings of different diameters. When the outer surface of the support ring 304 abuts against the inner surface of the pipe fitting, it forms a uniform radial support force, suitable for processing various specifications of pipe fittings, significantly improving the versatility of the component. The driving block 310 drives the ratchet 308 to rotate, thereby driving the rotating disk 307 to rotate synchronously. The driving force of the inclined groove 309 on all connecting rods 311 remains consistent, ensuring that the sliding distance of each connecting rod 311 along the straight groove 303 is the same, so that the support ring 304 always remains concentric with the pipe fitting. The synchronous adjustment mechanism avoids uneven force on the pipe fitting caused by the offset of the support position, effectively preventing the pipe fitting from tilting or shaking during processing, ensuring the stability and reliability of the support.

[0041] The base 101 of the main support component 1 provides the installation foundation for the overall structure. The horizontal slide 102 and the vertical guide rod 104 provide guidance for the horizontal movement of the sliding mounting plate 201. The horizontal screw 103 drives the sliding mounting plate 201 to move along the horizontal slide 102 through thread transmission, thereby realizing the horizontal adjustment of the support position. The vertical screw 106 in the lifting slide 105 is threadedly connected to the placement plate 108. With the guiding effect of the horizontal guide rod 107, the height of the placement plate 108 and the cutting component 109 above can be adjusted by rotating the vertical screw 106 to adapt to the cutting needs of different pipe diameters.

[0042] The lateral support adjustment mechanism 2 consists of a lateral adjustment mechanism and an annular support mechanism. The lateral adjustment mechanism is connected to the lateral screw 103 via a sliding mounting plate 201, thereby adjusting the lateral position of the annular support mechanism to accommodate pipes of different lengths. In the annular support mechanism, the adjusting screw 208 drives the clamping block 209 to move towards the center via a threaded transmission. Multiple clamping blocks 209 work together to clamp and fix the pipe from the outside. The drive motor 203 drives the annular mounting frame 207 and the clamped pipe to rotate via the meshing transmission of the drive gear 204 and the mating toothed ring 210, facilitating the cutting assembly 109 to cut the pipe at different angles.

[0043] The adjustable support assembly 3 drives the ratchet 308 to rotate via the drive block 310. The ratchet 308 drives the rotating disk 307 to rotate synchronously. The inclined groove 309 on the rotating disk 307 slides with the connecting rod 311, forcing the connecting rod 311 to slide radially along the straight groove 303 of the fixed plate 302, thereby driving the support ring 304 to move synchronously. The support ring 304 expands outward from the inside of the pipe and abuts against the inner surface of the pipe fitting, forming a uniform radial support force. It clamps with the outer side of the ring support mechanism to achieve double fixation of the inside and outside of the pipe, avoiding the pipe from shaking during the cutting process. The above is the overall working process of the present invention. This step can be repeated next time it is used. The actual operation process is very simple and easy.
