Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a multi-angle metal pipe grinding and fixing clamp. Background Technology

[0002] Metal pipes often need to be cut during production, and the cut end faces are often rough and not smooth. Therefore, grinding devices are usually used to grind the end faces of metal pipes. In order to fix the metal pipes during grinding, a fixing clamp is usually used. However, in actual use, in order to improve the grinding effect, it is often necessary to grind the end faces of the pipes at multiple angles. However, the structure of existing clamps is mostly simple, and the angle cannot be adjusted after the metal pipes are clamped. This means that if you want to perform multi-angle grinding, you need to adjust the angle of the grinding wheel on the grinding device, which is extremely inconvenient and not conducive to use. Therefore, a multi-angle metal pipe grinding fixing clamp is proposed. Utility Model Content

However, the structure of existing fixtures is mostly relatively simple, and the angle of the metal pipe cannot be adjusted after it is clamped. This means that if you want to perform multi-angle grinding, you need to adjust the angle of the grinding wheel on the grinding device, which is extremely inconvenient and detrimental to its use.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a multi-angle metal pipe grinding and fixing fixture, which has the following beneficial effects:

[0014] This multi-angle metal pipe grinding and fixing fixture works by extending one end of the metal pipe between two clamping blocks, with the end face to be ground facing upwards. Two electric telescopic rods are then activated to move the two clamping blocks relative to each other, thus clamping and fixing the metal pipe. When the angle of the top of the metal pipe needs to be adjusted, a second servo motor is activated to drive a worm gear to rotate, which in turn drives the two mounting shafts, rectangular frame, cylinder, and the metal pipe to rotate forward or backward.

Furthermore, when grinding the tilted metal pipe, a first servo motor can be activated to drive a drive gear to rotate, which in turn drives the cylinder and the metal pipe to rotate, grinding the outer circumference of the top of the metal pipe. This improves grinding efficiency and enhances usability. Attached Figure Description

The controller 9 can be of model CPM1A-10CDR-A-V1.

[0021] A first drive assembly 10 is fixedly installed on the bottom right side of the rectangular frame 4, with one end extending into the interior and fixedly connected to the outside of the cylinder 5. The first drive assembly 10 includes a first servo motor 101. The first servo motor 101 located on the right side of the cylinder 5 is fixedly installed on the bottom of the rectangular frame 4. A first protective shell 102 located outside the first servo motor 101 is fixedly installed on the bottom of the rectangular frame 4. The output shaft of the first servo motor 101 extends into the interior of the rectangular frame 4 and a drive gear 103 located on the right side of the cylinder 5 is fixedly installed. A driven gear 104 located inside the rectangular frame 4 and meshing with the drive gear 103 at one end is fixedly installed on the outside of the cylinder 5.

[0022] A second protective shell 11 located outside the left mounting shaft 3 is fixedly installed on the left side of the left mounting plate 2. A second drive assembly 12 is fixedly installed on the outside of the left mounting shaft 3, with one end movably connected to the inner top wall of the second protective shell 11 and the other end fixedly connected to the left side of the left mounting plate 2. The second drive assembly 12 includes a second servo motor 121.

A worm wheel 123 located inside the second protective shell 11 and meshing with the worm gear 122 is fixedly installed on the outside of the left mounting shaft 3. The model of the first servo motor 101 and the second servo motor 121 is YB2-315S-6-70.

[0023] All electrical components mentioned in this article are electrically connected to the controller 9 and the power supply. The control method of this utility model is controlled by the controller 9. The control circuit of the controller 9 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0024] In use, the fixing clamp is installed on the grinding device, with the cylinder 5 positioned below the grinding wheel. One end of the metal tube is then inserted between the two clamping blocks 7, with the end face to be ground facing upwards. Next, the two electric telescopic rods 8 are activated to move the two clamping blocks 7 relative to each other, thus clamping and fixing the metal tube. At this point, the grinding wheel on the grinding device moves downwards to grind the top of the metal tube. When the angle of the top of the metal tube needs to be adjusted, the second servo motor 121 is activated to rotate the worm gear 122, which in turn drives the two mounting shafts 3, the rectangular frame 4, the cylinder 5, and the metal tube to rotate forward or backward via the worm wheel 123. This changes the top of the metal tube from a horizontal position to a forward or backward tilted position, thus grinding the metal tube. The tilt angle at the top is adjusted, and the grinding wheel on the grinding device is moved downwards again to make the grinding wheel contact the top of the tilted metal tube. This allows for multi-angle grinding of the top of the metal tube. Furthermore, while grinding the tilted metal tube, the first servo motor 101 can be activated to drive the drive gear 103 to rotate, which in turn drives the cylinder 5 and the entire metal tube to rotate via the driven gear 104. (Since the first servo motor 101 can rotate in both directions, in actual use, the first servo motor 101 can be rotated back and forth to drive the cylinder 5 to rotate back and forth, thus ensuring the normal use of the fixture.) This allows for grinding of the outer circumference of the top of the metal tube, improving grinding efficiency and facilitating its use.

[0025] In summary, this multi-angle metal pipe grinding and fixing fixture, by extending one end of the metal pipe between two clamping blocks 7 with the end face to be ground facing upwards, can then activate two electric telescopic rods 8 to move the two clamping blocks 7 relative to each other, thereby clamping and fixing the metal pipe. When it is necessary to adjust the angle of the top of the metal pipe, the second servo motor 121 can be activated to drive the worm gear 122 to rotate, which in turn drives the two mounting shafts 3, rectangular frame 4, cylinder 5, and the metal pipe as a whole to rotate forward or backward through the worm wheel 123, thereby changing the top of the metal pipe from a horizontal state to a forward or backward tilted state, thus adjusting the tilt angle of the top of the metal pipe, and enabling multi-angle grinding of the top of the metal pipe. When grinding a tilted metal pipe, the first servo motor 101 can be activated to drive the drive gear 103 to rotate, which in turn drives the cylinder 5 and the metal pipe as a whole to rotate via the driven gear 104. This allows for grinding of the outer circumference of the top of the metal pipe, thereby improving grinding efficiency and making it more convenient to use. This solves the problem that existing fixtures often require multi-angle grinding of the pipe end face in order to improve the grinding effect. However, the structure of existing fixtures is mostly simple, and the angle of the metal pipe cannot be adjusted after it is clamped. This means that if you want to perform multi-angle grinding, you need to adjust the angle of the grinding wheel on the grinding device, which is extremely inconvenient and detrimental to use.
