Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting production, in particular to a pipe fitting grinding device applicable to different pipe diameters. Background Art

[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow diversion, sealing, and support. When grinding pipe fittings, the pipe fittings need to be firmly fixed before subsequent processing operations. Due to the different sizes of pipe fittings, the grinding processing ranges are also different, and the existing equipment cannot be applied to pipe fittings of different pipe diameters.

[0003] Chinese Patent with Publication No. CN219005501U discloses a pipe fitting grinding device, which includes an operating table. A rodless cylinder is fixedly embedded on the right side of the top of the operating table. The movable end of the rodless cylinder is fixedly connected with a moving seat. The top of the moving seat is fixedly connected with an L-shaped positioning seat. A grinding box is arranged on the left side of the rodless cylinder. Guide seats are symmetrically arranged on the left side of the top of the operating table. The grinding box is located on the right side of the guide seats. The operation of assembling and clamping pipe fittings is simpler. And the clamping structure and the pipe material rotate simultaneously, avoiding the situation that the clamping structure scratches the pipe material when the pipe material rotates alone. Multiple points on the outer side of the pipe material can be ground simultaneously. Compared with the single grinding position, the overall grinding efficiency of the pipe material can be effectively improved. The nozzle performs dust removal operations on the iron filings ground at high speed to avoid the iron filings remaining on the pipe fitting surface during grinding from damaging the pipe fitting.

[0004] In the above technical solution, by rotating the limit screw inside the rotating internal thread tube, the inner end of the limit screw extends out of the limit tube, and the outer wall of the pipe material is clamped and fixed by the abutting block at its bottom end. The grinding wheel is driven by the second motor to rotate inside the arc-shaped groove, so that the high-speed rotating pipe material and the high-speed rotating grinding wheel can quickly grind the outer surface of the pipe material. However, in the above existing technical solution, since the arc-shaped groove is fixed and the grinding wheel is arranged inside the arc-shaped groove, only one specification of pipe fitting can be ground, and the adaptability is low.

[0024] The present utility model provides an improved pipe fitting grinding device applicable to different pipe diameters. The technical solution of the present utility model is as follows:

[0025] As Figure 1 - Figure 4As shown in the figure, a pipe fitting grinding device applicable to different pipe diameters includes a base 1. A chute 11 is provided on the top wall surface of the base 1. A first motor 2 is fixedly installed on the side wall of the base 1. The output end of the first motor 2 is fixedly installed with a lead screw 21. The lead screw 21 is rotatably installed on the inner side wall of the chute 11. It also includes two clamping components. The two clamping components are arranged on the inner side wall of the base 1 and are axially symmetrically distributed. The clamping component includes an electric telescopic rod 4. The electric telescopic rod 4 is fixedly installed on the inner side wall of the base 1.

A threaded rod 52 is rotatably installed on the top wall surface of the pressing plate 51. The threaded rod 52 penetrates through the mounting frame 5 and extends to the top of the mounting frame 5. A handle is fixedly installed on the top wall surface of the threaded rod 52. The setting of the handle facilitates rotating the threaded rod 52 to drive the pressing plate 51 to move. Two abrasive belts 6 are arranged inside the pressing plate 51. The setting of the pressing plate 51 facilitates fixing the abrasive belts 6. The abrasive belts 6 are flexible. An installation block is spirally installed on the side wall of the chute 11. A moving plate 22 is fixedly installed on the top wall surface of the installation block. A second motor 3 is fixedly installed on the side wall of the moving plate 22 away from the abrasive belts 6. A three-jaw chuck 31 is arranged on the side wall of the moving plate 22 close to the abrasive belts 6. The three-jaw chuck 31 is a prior art and will not be elaborated here. The three-jaw chuck 31 is power-connected to the second motor 3. Place one end of the two abrasive belts 6 inside the mounting frame 5. Rotate the handle to drive the threaded rod 52 to rotate, so that the pressing plate 51 presses the abrasive belts 6 to fix the abrasive belts 6. Place the pipe fitting on the three-jaw chuck 31 to fix the pipe fitting. When grinding the pipe fitting, first place the pipe fitting between the two abrasive belts 6. Start the two electric telescopic rods 4 to tighten the abrasive belts 6. Then start the second motor 3 to drive the pipe fitting to rotate, so that the abrasive belts 6 grind the surface of the pipe fitting. Then start the first motor 2. The first motor 2 drives the moving plate 22 to approach the abrasive belts 6, so as to grind the whole pipe fitting, making the grinding of the pipe fitting more comprehensive and improving the adaptability of the device.

[0026] As Figure 1 , Figure 2 and Figure 4As shown in the figure, in one embodiment, a rotating rod 7 is rotatably installed on the side wall of the installation frame 5. A connecting rod 71 is fixedly installed on the side wall of the rotating rod 7. A torsion spring 8 is sleeved on the side wall of the rotating rod 7. The torsion spring 8 facilitates the reset of the connecting rod 71, so that the connecting rod 71 is in a horizontal state. A limiting rod 72 is fixedly installed on the side wall of the connecting rod 71 close to the abrasive belt 6. The limiting rod 72 is located between the two abrasive belts 6. A fixed rod 13 is fixedly installed on the inner side wall of the base 1. A pressing rod 14 is fixedly installed on the bottom wall surface of the fixed rod 13.

The support rod 12 makes the pipe more stable during grinding; before the pipe is placed between the two abrasive belts 6, the two electric telescopic rods 4 are started to drive the two installation frames 5 to approach each other, so that the two abrasive belts 6 are bent. During the approaching process of the two installation frames 5, the pressing rod 14 will first contact the side wall of the connecting rod 71 and squeeze the connecting rod 71, so that the connecting rod 71 rotates around the rotating rod 7. The rotation of the connecting rod 71 drives the limiting rod 72 to rotate. The limiting rod 72 between the two abrasive belts 6 guides the bending directions of the two abrasive belts 6, so that the two abrasive belts 6 are relatively far away from each other when bent, which facilitates the subsequent placement of the pipe and improves the practicability of the device.

[0027] The specific working method is as follows: Place one end of the two abrasive belts 6 inside the installation frame 5. Rotate the handle to drive the threaded rod 52 to rotate, so that the pressing plate 51 presses the abrasive belt 6 to fix the abrasive belt 6. The two electric telescopic rods 4 are started to drive the two installation frames 5 to approach each other, so that the two abrasive belts 6 are bent. During the approaching process of the two installation frames 5, the pressing rod 14 will first contact the side wall of the connecting rod 71 and squeeze the connecting rod 71, so that the connecting rod 71 rotates around the rotating rod 7. The rotation of the connecting rod 71 drives the limiting rod 72 to rotate. The limiting rod 72 between the two abrasive belts 6 guides the bending directions of the two abrasive belts 6, so that the two abrasive belts 6 are relatively far away from each other when bent, which facilitates the subsequent placement of the pipe. Place the pipe on the three-jaw chuck 31 to fix the pipe. When grinding the pipe, first place the pipe between the two abrasive belts 6. Start the two electric telescopic rods 4 to make the two installation frames 5 move away from each other to tighten the abrasive belt 6. Then start the second motor 3 to drive the pipe to rotate, so that the abrasive belt 6 grinds the surface of the pipe. Then start the first motor 2. The first motor 2 drives the moving plate 22 to approach the abrasive belt 6, so as to grind the whole pipe, making the grinding of the pipe more comprehensive and improving the adaptability of the device.
