Description

Technical Field

[0001] The utility model belongs to the technical field of water pipes, and particularly relates to a clamping device for cutting water pipes. Background Art

[0002] Water pipes are a type of piping system used to transport water or other liquids. They are widely used in homes, commercial buildings, industrial facilities, and urban infrastructure to ensure that water resources can be transported from the source to where they are needed. Existing water pipes require a special clamping device for cutting water pipes when they are processed and used.

[0003] Existing clamping devices for cutting water pipes usually require synchronous clamping of both ends of the water pipe to ensure its stability. However, this design requires an independent drive on each side, which increases the manufacturing cost of the entire device. Utility Model Content

[0004] In view of this, the utility model provides a clamping device for cutting water pipes, which can realize the synchronous movement of all clamping plates through a synchronous drive mechanism with only one motor, simplifying the structure and reducing costs. It can conveniently and quickly move the required cutting part of the water pipe to the appropriate position, and can adapt to the needs of cutting water pipes of different lengths.

[0005] In order to solve the above technical problems, the utility model provides a clamping device for cutting water pipes, comprising a machine base and a guide rod symmetrically arranged between the two ends of the machine base inner cavity, and symmetrically distributed sliding clamping seats are slidably connected at both ends between the two guide rods, and both ends of the sliding clamping seat are provided with avoidance grooves, and the bottoms of the avoidance grooves are rotatably connected to rotating rods, and the outer arc surfaces of the rotating rods are provided with clamping plates, and the clamping plates are respectively located in the avoidance grooves adjacent to the same side, and a transmission rod is rotatably connected between the two ends of the machine base inner cavity away from each guide rod, and a slide groove is provided in the middle of the rotating rod, and the transmission rods are respectively slidably connected to the slide grooves adjacent to the same side, and one end of the machine base is also provided with a synchronous driving mechanism for synchronously driving the transmission rod to rotate, that is, only one motor is required to realize the synchronous movement of all clamping plates, which simplifies the structure and reduces the cost, can conveniently and quickly move the required cutting part of the water pipe to the appropriate position, and can adapt to the needs of cutting water pipes of different lengths.

[0006] The two clamping plates on the same sliding clamping seat are staggered to avoid the two clamping plates 104 from interfering with each other.

[0007] The synchronous drive mechanism includes a mounting plate arranged at one end of the machine base, and the outer end of the mounting plate is rotatably connected to a rotating rod. Both ends of the rotating rod are provided with symmetrically distributed driving bevel gears, and the end of the transmission rod close to the mounting plate is provided with a driven bevel gear. The driven bevel gears are respectively engaged and connected with the adjacent driving bevel gears on the same side, thereby playing the role of synchronous drive.

[0008] A motor is provided on one side of the machine base near one end of the mounting plate, and the output shaft of the motor is fixedly connected to one end of the rotating rod, which plays a driving role.

[0009] A bidirectional screw is rotatably connected in the middle between the two ends of the inner cavity of the machine base. A threaded hole is provided at the bottom end of the sliding clamping seat near the bidirectional screw. The two ends of the bidirectional screw are respectively threadedly connected to the adjacent threaded holes on the same side, which can drive the two sliding clamping seats 102 and their ancillary mechanisms to move synchronously toward or oppositely along the guide rod 101.

[0010] A protective cover is provided on one end of the machine base close to the mounting plate, and an avoidance opening adapted to the output shaft is provided on the other end of the protective cover close to the motor. The mounting plate, rotating rod, driving bevel gear and driven bevel gear are all located inside the protective cover, which can effectively prevent dust, debris and other debris from entering the transmission system.

[0011] The inner arc surface of the sliding clamping seat is provided with a plurality of guide wheels arranged along the circumference of the axis, which can conveniently and quickly move the required cutting part of the water pipe to the appropriate position.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. The rotation of the motor output shaft drives the rotating rod and the driving bevel gears at both ends to rotate synchronously. While the driving bevel gear rotates, it drives the transmission rod to rotate synchronously through the driven bevel gear meshing with it. When the transmission rod rotates, it drives the rotating rod and the clamping plate on it to gradually approach the water pipe to be clamped, and finally clamp the water pipe. Only one motor is required to achieve the synchronous movement of all clamping plates, which simplifies the structure and reduces costs.

[0014] 2. By placing the water pipe between the two sliding clamping seats and moving the water pipe through the guide wheel, the required cutting part of the water pipe can be moved to the appropriate position conveniently and quickly.

[0015] 3. Rotate the bidirectional screw according to the length of the water pipe. Affected by the threaded connection relationship between the bidirectional screw and the wire hole, the bidirectional screw drives the two sliding clamping seats and their auxiliary mechanisms to move synchronously toward or oppositely along the guide rod when rotating, thereby adapting to the needs of cutting water pipes of different lengths.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] This embodiment provides a clamping device for cutting water pipes, such as Figure 1-4 As shown: It includes a machine base 100 and a guide rod 101 symmetrically arranged between the two ends of the inner cavity of the machine base 100, and the two guide rods 101 are slidably connected at both ends with a symmetrically distributed sliding clamping seat 102, and both ends of the sliding clamping seat 102 are provided with an avoidance groove, and the bottom of the avoidance groove is rotatably connected with a rotating rod 103, and the bottom of the avoidance groove is provided with a rotating hole 1 for providing rotation support for the rotating rod 103, and the outer arc surface of the rotating rod 103 is provided with a clamping plate 104, and the clamping plates 104 are respectively located in the adjacent avoidance grooves on the same side. A transmission rod 105 is rotatably connected between the two ends of the inner cavity 100, away from each guide rod 101. A rotating hole 2 is provided between the two ends of the inner cavity of the machine base 100, away from each guide rod 101, for providing rotation support for the transmission rod 105. The two ends of the transmission rod 105 are cylindrical and the middle part is rectangular. A slide groove is provided in the middle of the rotating rod 103, and the slide groove is a rectangular slide groove. The transmission rod 105 is respectively slidably connected to the adjacent slide grooves on the same side. One end of the machine base 100 is also provided with a synchronous drive mechanism for synchronously driving the transmission rod 105 to rotate.

[0023] Relevant staff drive the two sliding clamping seats 102 and their attached mechanisms to move synchronously toward or oppositely along the guide rod 101 to meet the needs of cutting water pipes of different lengths. After that, the water pipe is placed between the two sliding clamping seats 102, and then the transmission rod 105 is driven to rotate. The rotation of the transmission rod 105 will drive the rotating rod 103 and the clamping plate 104 thereon to synchronously approach the water pipe to be clamped, and finally clamp the water pipe. Only one motor 204 is required to achieve the synchronous movement of all clamping plates 104, which simplifies the structure and reduces costs.

[0024] like Figure 1-4 As shown, the two clamping plates 104 located on the same sliding clamping seat 102 are staggered to avoid the two clamping plates 104 from interfering with each other.

[0025] like Figure 2-4 As shown, the synchronous drive mechanism includes a mounting plate 200 arranged at one end of the machine base 100, and the outer end of the mounting plate 200 is rotatably connected to the rotating rod 201. The outer end of the mounting plate 200 is provided with a rotating hole three for providing rotation support for the rotating rod 201. Both ends of the rotating rod 201 are provided with symmetrically distributed driving bevel gears 202, and the end of the transmission rod 105 close to the mounting plate 200 is provided with a driven bevel gear 203, and the driven bevel gears 203 are respectively meshed and connected with the adjacent driving bevel gears 202 on the same side.

[0026] The rotating rod 201 and the driving bevel gears 202 at both ends rotate synchronously. When the driving bevel gear 202 rotates, it drives the transmission rod 105 to rotate synchronously through the driven bevel gear 203 meshing with it, thereby playing a role of synchronous driving.

[0027] like Figure 1-3 As shown, a motor 204 is provided on one side of the base 100 near one end of the mounting plate 200 , and the output shaft of the motor 204 is fixedly connected to one end of the rotating rod 201 . The rotation of the output shaft of the motor 204 drives the motor 204 and its auxiliary mechanisms to rotate synchronously.

[0028] like Figure 1-3 As shown, a bidirectional screw rod 300 is rotatably connected in the middle between the two ends of the inner cavity of the machine base 100, and a rotating hole four is provided in the middle between the two ends of the inner cavity of the machine base 100 for providing rotation support for the bidirectional screw rod 300. A threaded hole is provided at the bottom end of the sliding clamping seat 102 near the bidirectional screw rod 300, and the two ends of the bidirectional screw rod 300 are respectively threadedly connected to the adjacent threaded holes on the same side. When the bidirectional screw rod 300 rotates, it drives the two sliding clamping seats 102 and their ancillary mechanisms to move synchronously toward or oppositely along the guide rod 101.

[0029] like Figure 1As shown, a protective cover 400 is provided at one end of the machine base 100 close to the mounting plate 200, and a avoidance opening adapted to the output shaft thereof is provided at one end of the protective cover 400 close to the motor 204. The mounting plate 200, the rotating rod 201, the driving bevel gear 202 and the driven bevel gear 203 are all located in the protective cover 400. The protective cover 400 can effectively prevent dust, debris and other sundries from entering the transmission system, while providing a certain degree of safety for the operator. The protective cover 400 is designed with a avoidance opening to facilitate the output shaft of the motor 204 to pass through and connect with the rotating rod 201.

[0030] like Figure 1-2 As shown, the inner arc surface of the sliding clamping seat 102 is provided with a plurality of guide wheels 500 arranged along the circumference of its axis, and the inner arc surface of the sliding clamping seat 102 is provided with a rotation groove for providing rotation support for each guide wheel 500. By moving the water pipe through the guide wheel 500, the required cutting part of the water pipe can be moved to the appropriate position conveniently and quickly.

[0031] The working principle of the clamping device for cutting water pipes provided by the present invention is as follows: first, the relevant staff rotates the bidirectional screw rod 300 according to the length of the water pipe. Affected by the threaded connection relationship between the bidirectional screw rod 300 and the wire hole, the bidirectional screw rod 300 drives the two sliding clamping seats 102 and their attached mechanisms to move synchronously toward or oppositely along the guide rod 101 when rotating, so as to adapt to the needs of cutting water pipes of different lengths. After that, the water pipe is placed between the two sliding clamping seats 102, and the water pipe is moved by the guide wheel 500, which can conveniently and quickly move the required cutting part of the water pipe to the appropriate position. After the movement is completed, the motor 204 is regulated to operate, and the output shaft of the motor 204 rotates to drive the rotating rod 201 The driving bevel gears 202 at both ends rotate synchronously. When the driving bevel gear 202 rotates, it drives the transmission rod 105 to rotate synchronously through the driven bevel gear 203 meshing with it. When the transmission rod 105 rotates, it will drive the rotating rod 103 and the clamping plate 104 thereon to gradually approach the water pipe to be clamped, and finally clamp the water pipe. Only one motor 204 is required to achieve the synchronous movement of all clamping plates 104, which simplifies the structure and reduces the cost. The protective cover 400 can effectively prevent dust, debris and other debris from entering the transmission system, while providing a certain safety guarantee for the operator. The protective cover 400 is designed with an avoidance opening to facilitate the output shaft of the motor 204 to pass through and connect with the rotating rod 201.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
