Abstract
Description
Technical Field
[0001] This utility model relates to the field of tee processing technology, specifically an adjustable grinding device for tee processing. Background Technology
[0002] A tee is a pipe with three open fittings. Tees are widely used in chemical pipe fittings, mainly for changing the direction of fluids. They are widely used in pipeline networks for transporting liquids and gases. Depending on the medium being transported, tees are made of materials such as cast iron, cast steel, cast copper, and cast aluminum. During the processing of tees, the inner wall of the pipe openings may have unevenness or burrs, so grinding is required.
[0003] Tee pipes are generally T-shaped or Y-shaped, but ordinary grinding equipment can only grind T-shaped or Y-shaped single tee pipes. It is inconvenient to adjust according to the type of tee pipe, which has limitations. Moreover, it is inconvenient to grind the inner and outer walls of the pipe opening. In addition, the clamping of the tee pipe is not firm enough during grinding, which affects the grinding accuracy. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable grinding device for tee machining to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable grinding device for T-joint machining, comprising a device body, a clamp, a clamping rod, a clamping block, and a grinding head. The clamp is installed on the outer wall of the device body, and the clamping block is disposed on the outer wall of the clamp. A movable block is disposed inside the clamp at the position of the clamping block, and a second stepper motor is installed inside the movable block. The output end of the second stepper motor is fixedly connected to the clamping block. A bidirectional lead screw is installed at the bottom of the clamp, and clamping rods are threaded onto both sides of the surface of the bidirectional lead screw. One end of the clamping rods extends to the outside of the clamp. A turntable is installed below the clamp, and a first movable seat is disposed at the top of the turntable. A second movable seat is disposed above the first movable seat, and a third servo motor is installed inside the second movable seat. The grinding head is installed at the output end of the third servo motor.
[0006] Preferably, a first geared motor is installed at the bottom of the main body of the device below the turntable, and the output end of the first geared motor is fixedly connected to the turntable.
[0007] Preferably, a second servo motor is installed inside the turntable, and a translation screw is installed at the output end of the second servo motor. The bottom end of the first movable seat extends into the interior of the turntable and is threadedly connected to the translation screw.
[0008] Preferably, a first servo motor is installed on the outer wall of the clamp at the position of the bidirectional lead screw, and the output end of the first servo motor is fixedly connected to the bidirectional lead screw.
[0009] Preferably, the upper surface of the clamping block is an arc surface, and the lower surface of the clamping block is a plane.
[0010] Preferably, a second cylinder is installed inside the first movable seat, and the output end of the second cylinder is fixedly connected to the second movable seat.
[0011] Preferably, a first cylinder is mounted on the top of the clamp, and the output end of the first cylinder extends into the interior of the clamp and is fixedly connected to the movable block.
[0012] Preferably, a first stepper motor is installed inside the main body of the device at the clamp position, and the output end of the first stepper motor is fixedly connected to the clamp.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The T-shaped tee is placed between the clamping block and the clamping rod on one side of the fixture. The first servo motor drives the bidirectional lead screw to rotate, so that the clamping rod clamps and supports the T-shaped tee from both sides. The first cylinder drives the movable block to move down, so that the clamping block presses down on the T-shaped tee from above, thus firmly clamping the T-shaped tee. When it is necessary to grind the Y-shaped tee, the second stepper motor drives the clamping block to flip so that the arc surface of the clamping block faces down. Repeat the above steps to clamp the Y-shaped tee. This device optimizes the structure of the fixture. By switching the orientation of the clamping block, it is convenient to grind T-shaped and Y-shaped tee. Moreover, the three-point clamping method ensures firm and reliable clamping, is not easy to loosen, and has high grinding accuracy.
[0015] The second cylinder drives the second movable seat to move upward, causing the grinding head to extend into the opening of the T-shaped tee pipe. The second servo motor drives the translation screw to rotate, causing the first movable seat to move the grinding head horizontally, so that the grinding head is in close contact with the inner wall of the pipe opening. The third servo motor drives the grinding head to rotate, and the first reduction motor drives the turntable to rotate. The grinding head rotates along the inner wall of the pipe opening to grind the inner wall. Then, the second cylinder drives the grinding head to move downward, the translation screw drives the grinding head to move horizontally, and the second cylinder drives the grinding head to move upward, so that the grinding head is in close contact with the outer wall of the pipe opening, thus grinding the outer wall of the pipe opening. This facilitates grinding both the inner and outer walls of the pipe opening. When one pipe opening is finished being ground, the first step motor drives the fixture to rotate, and the fixture drives the T-shaped tee pipe to rotate, so that the remaining two pipe openings can be ground.

[0025] Please see Figure 1-6An embodiment of this utility model provides an adjustable grinding device for T-joint processing, comprising a device body 1, a clamp 4, a clamping rod 6, a clamping block 9, and a grinding head 17. The clamp 4 is installed on the outer wall of the device body 1, and the clamping block 9 is set on the outer wall of the clamp 4. A movable block 8 is provided inside the clamp 4 at the position of the clamping block 9, and a second stepper motor 19 is installed inside the movable block 8.

A bidirectional lead screw 5 is installed at the bottom of the clamp 4, and the clamping rod 6 is threaded on both sides of the surface of the bidirectional lead screw 5. One end of the clamping rod 6 extends to the outside of the clamp 4.
[0026] Specifically, the T-shaped tee is placed between the clamping block 9 and the clamping rod 6 on one side of the clamp 4. The first servo motor 10 drives the bidirectional lead screw 5 to rotate, causing the clamping rod 6 to clamp and support the T-shaped tee from both sides. The first cylinder 7 drives the movable block 8 to move downward, causing the clamping block 9 to press the T-shaped tee down from above. (Refer to the attached diagram.) Figure 1 , Four This will firmly clamp the T-shaped tee pipe;
[0027] A turntable 2 is installed below the fixture 4, and a first movable seat 13 is provided at the top of the turntable 2. A second movable seat 15 is provided above the first movable seat 13, and a third servo motor 16 is installed inside the second movable seat 15.

[0028] A first reduction motor 3 is installed at the bottom of the main body 1 of the device below the turntable 2, and the output end of the first reduction motor 3 is fixedly connected to the turntable 2.
[0029] The turntable 2 is equipped with a second servo motor 11, and the output end of the second servo motor 11 is equipped with a translation screw 12. The bottom end of the first movable seat 13 extends into the turntable 2 and is threadedly connected to the translation screw 12.
[0030] A first servo motor 10 is installed on the outer wall of the clamp 4 at the position of the bidirectional lead screw 5, and the output end of the first servo motor 10 is fixedly connected to the bidirectional lead screw 5.
[0031] Specifically, the second cylinder 14 drives the second movable seat 15 to move upward, so that the grinding head 17 extends into the opening of the T-shaped tee pipe. The second servo motor 11 drives the translation screw 12 to rotate, so that the first movable seat 13 drives the grinding head 17 to move horizontally. The grinding head 17 is in close contact with the inner wall of the pipe opening. The third servo motor 16 drives the grinding head 17 to rotate. The first reduction motor 3 drives the turntable 2 to rotate. The grinding head 17 rotates on its own axis and along the inner wall of the pipe opening to grind the inner wall of the pipe opening. Then, the second cylinder 14 is controlled to drive the grinding head 17 to move downward. The translation screw 12 drives the grinding head 17 to move horizontally. The second cylinder 14 drives the grinding head 17 to move upward, so that the grinding head 17 is in close contact with the outer wall of the pipe opening, and the outer wall of the pipe opening can be ground. This makes it convenient to grind the inner and outer walls of the pipe opening.
[0032] Once one pipe opening is polished, the first stepper motor 18 drives the fixture 4 to rotate, and the fixture 4 drives the T-shaped tee pipe to rotate, so that the remaining two pipe openings can be polished.
[0033] When grinding the Y-shaped tee pipe is required, the second stepper motor 19 drives the clamping block 9 to rotate, so that the arc surface of the clamping block 9 faces downwards. (Refer to the attached document.) Figure 5 Repeat the above steps to clamp the Y-shaped tee pipe. This device optimizes the structure of the clamp 4. By switching the orientation of the clamping block 9, it is convenient to grind the T-shaped and Y-shaped tee pipes. Moreover, the three-point clamping method is adopted, which makes the clamping firm and reliable, not easy to loosen, and the grinding accuracy is high.
[0034] The upper surface of clamping block 9 is curved, and the lower surface of clamping block 9 is flat.
[0035] The second cylinder 14 is installed inside the first movable seat 13, and the output end of the second cylinder 14 is fixedly connected to the second movable seat 15.

[0038] In this embodiment of the application, the T-shaped tee pipe is first placed between the clamping block 9 and the clamping rod 6 on one side of the clamp 4. The first servo motor 10 drives the bidirectional lead screw 5 to rotate, so that the clamping rod 6 clamps and supports the T-shaped tee pipe from both sides. The first cylinder 7 drives the movable block 8 to move down, so that the clamping block 9 presses down on the T-shaped tee pipe from above. (Refer to the attached document.) Figure 1 , FourThis firmly clamps the T-shaped tee pipe. Next, the second cylinder 14 drives the second movable seat 15 upwards, causing the grinding head 17 to extend into the opening of the T-shaped tee pipe. The second servo motor 11 drives the translation screw 12 to rotate, causing the first movable seat 13 to move the grinding head 17 horizontally, bringing it tightly against the inner wall of the pipe opening. The third servo motor 16 drives the grinding head 17 to rotate, and the first reduction motor 3 drives the turntable 2 to rotate. The grinding head 17 rotates along the inner wall of the pipe opening, grinding the inner wall. Then, the second cylinder 14 is controlled to drive the grinding head 17 to rotate. The grinding head 17 moves downward, the translation screw 12 drives the grinding head 17 to move horizontally, and the second cylinder 14 drives the grinding head 17 to move upward, bringing the grinding head 17 close to the outer wall of the pipe opening, thus facilitating the grinding of both the inner and outer walls of the pipe opening. After one pipe opening is ground, the first stepper motor 18 drives the clamp 4 to rotate, and the clamp 4 drives the T-shaped tee pipe to rotate, allowing the remaining two pipe openings to be ground. When it is necessary to grind the Y-shaped tee pipe, the second stepper motor 19 drives the clamp block 9 to flip, so that the arc surface of the clamp block 9 faces downward. (Refer to the attached diagram.) Figure 5 Repeat the above steps to clamp the Y-shaped tee pipe. The device optimizes the structure of the clamp 4. By switching the orientation of the clamping block 9, it is convenient to grind the T-shaped and Y-shaped tee pipes. Moreover, the three-point clamping method is used, which makes the clamping firm and reliable, not easy to loosen, and the grinding accuracy is high.
[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments.
