Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing, and more specifically, to a pipe clamping device. Background Technology
[0002] In the agricultural sector, PVC pipe fittings are widely used in key areas such as irrigation systems and drainage projects due to their significant advantages, including corrosion resistance, low cost, and ease of installation. When drilling PVC pipe fittings, it is necessary to follow conventional drilling methods while also incorporating more efficient technologies to meet the specific needs of agricultural production.
[0003] During the drilling process of pipe fittings, a clamping device is needed to clamp the pipe fittings. Then, the machine or manual drilling is used to drill holes in the outer wall of the pipe fittings. Existing clamping devices usually use two chucks to clamp the two ends of the pipe fittings respectively. One of the chucks is connected to a rotating shaft. The pipe is rotated by manually rotating the rotating shaft, which allows drilling in the circumferential direction. However, when the drill bit is drilling, in order to ensure the drilling quality, the rotating shaft needs to be stabilized manually. Since manual control is difficult, this fixing effect is not stable enough, which may lead to poor drilling results. Utility Model Content
[0004] The purpose of this invention is to overcome the limitations of existing pipe clamping devices that require manual fixing of the rotating shaft to achieve drilling, and to provide a pipe clamping device that eliminates the need for manual fixing of the pipe, thus ensuring drilling results.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A pipe clamping device is provided, including a base, a first rotating mechanism, a first fixing mechanism connected to the output end of the first rotating mechanism, a second fixing mechanism fixed on the base, and a locking member. The first rotating mechanism is rotatably connected to the base and its rotation axis is collinear with the axis of the pipe. The locking member is used to lock the rotation of the first rotating mechanism. The first fixing mechanism and the second fixing mechanism are respectively used to fix the two ends on the axis of the pipe.
[0007] This utility model discloses a pipe clamping device. Before machining the indexing hole of the pipe, one end of the pipe is fixed by a first fixing mechanism, and then the other end of the pipe is fixed by a second fixing mechanism, so that the pipe is firmly fixed. Then, the pipe can be drilled manually or by drilling equipment. After drilling a hole, the first rotating mechanism can be manually rotated, thereby driving the pipe fixed on the first fixing mechanism to rotate. When the pipe rotates to the appropriate position, the first rotating shaft is locked by a locking component, thereby restricting the rotation of the first rotating shaft. Then, the pipe is machined for the next indexing hole. Compared with the prior art, this device uses a locking component to lock the rotation of the first rotating shaft. No manual control is required during drilling, resulting in better stability and better drilling effect. The manual control of the first rotating shaft rotation allows for free adjustment of the drilling position compared with electric control, providing better adjustability.
[0008] Furthermore, the first rotating mechanism includes a grip and a first rotating shaft. The base is provided with a first bearing seat, and the first rotating shaft is rotatably connected to the first bearing seat. One end of the first rotating shaft is connected to the grip, and the other end is connected to the first fixing mechanism. The cooperation between the first rotating shaft and the first bearing seat provides better rotational stability, and the grip is convenient for hand gripping and force application.
[0009] Furthermore, the top of the first bearing seat is provided with a pin hole, and the first rotating shaft is evenly provided with a plurality of positioning holes along its circumference. The locking element is a pin, which passes through the pin hole and is inserted into the positioning hole. When the pipe is rotated to a suitable angle, the pin is inserted into the positioning hole to achieve fixation. Using a pin as a locking element makes disassembly and assembly convenient.
[0010] Furthermore, the first rotating shaft is provided with a scale along its circumference, marking the angles corresponding to the positioning holes. Operators can adjust the rotation angle of the first rotating shaft by observing the scale, which improves convenience.
[0011] Furthermore, the grip is a handwheel, and the rotation axis of the handwheel is collinear with the axis of the first rotating shaft. As a grip, the handwheel allows the operator to adjust the drilling position of the pipe fitting by rotating it, making operation convenient and effortless.
[0012] Furthermore, the first fixing mechanism is a chuck, on which at least two jaws are evenly arranged circumferentially. These jaws are used to support the inner wall of the pipe fitting. By turning the square hole on the chuck, the jaws can be controlled to move synchronously closer to or further away from its axis. When installing the pipe fitting, by adjusting the jaws to move away from their axis, the jaws press against the inner wall of the pipe fitting, thereby fixing the pipe fitting in place. When removing the pipe fitting, the square hole is turned in the opposite direction to release the jaws, thereby removing the pipe fitting. This provides better stability, and by using the chuck as the first fixing mechanism, the radial fixing of the pipe fitting is better achieved.
[0013] Furthermore, a second bearing seat is provided on the top of the base. The second fixing mechanism includes a second rotating shaft and a top tube connected to the output end of the second rotating shaft. The top tube is tapered, and its maximum outer diameter is greater than the inner diameter of the pipe. The axis of the top tube and the axis of the second rotating shaft are collinear with the axis of the pipe. The end of the top tube with the larger outer diameter is connected to the second rotating shaft. After one end of the pipe is installed on the first fixing mechanism, the top tube is inserted into the pipe. Because the maximum outer diameter of the top tube is greater than the inner diameter of the pipe, the top tube can apply an axial thrust to one end of the pipe, tightening the pipe and improving the stability of the pipe axis, thus improving drilling quality. The tapered shape of the top tube allows it to adapt to pipes with different inner diameters, resulting in better applicability.
[0014] Furthermore, the second shaft seat and the top surface of the machine base are slidably connected, and the sliding direction is along the axial direction of the second rotating shaft. Tightening the jacking component is achieved by sliding the second shaft seat, which offers better convenience.
[0015] Furthermore, the top of the base is provided with several guide rails parallel to the axis of the pipe, and both the first fixing mechanism and the second fixing mechanism are slidably connected to the guide rails. The guide rails improve the sliding stability of the first and second fixing mechanisms, and allow for adjustment of the distance between them to accommodate pipes of different lengths, thus enhancing applicability.
[0016] Furthermore, the first fixing mechanism and the guide rail are fixed together by fasteners, and the second fixing mechanism and the guide rail are also fixed together by fasteners. The fasteners enable quick locking and unlocking, improving convenience.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. Compared with existing technologies, this device uses a locking component to lock the rotation of the first rotating shaft, eliminating the need for manual control during drilling, resulting in better stability and drilling effect. The manual control of the first rotating shaft allows for free adjustment of the drilling position compared to electric control, providing better adjustability.
[0019] 2. By using a chuck as the first fixing mechanism, the radial fixing of the pipe fitting is better achieved, and the setting of the top pipe fitting is better achieved, ensuring the stability of the pipe fitting during drilling;
[0020] 3. The guide rail design improves the sliding stability of the first and second fixing mechanisms. By adjusting the distance between the first and second fixing mechanisms, it can accommodate pipes of different lengths, thus enhancing its applicability. Attached Figure Description

[0028] Example 1
[0029] A pipe clamping device, such as Figure 1 and Figure 2As shown, the device includes a base 100, a first rotating mechanism 200, a first fixing mechanism 300 connected to the output end of the first rotating mechanism 200, a second fixing mechanism 400 fixed to the base 100, and a locking member 230. The first rotating mechanism 200 includes a gripping member 210 and a first rotating shaft 220. A first shaft seat 110 is provided on the top of the base 100. One end of the first rotating shaft 220 is connected to the gripping member 210, and the other end is connected to the first fixing mechanism 300. The first fixing mechanism 300 and the second fixing mechanism 400 are also connected. 0 are used to fix the two ends on the axis of the pipe fitting. In this embodiment, the grip 210 is a handwheel 211. The rotation axis of the handwheel 211 is collinear with the axis of the first rotating shaft 220. The top of the first shaft seat 110 is provided with a pin hole. The first rotating shaft 220 is evenly provided with a positioning hole along the circumference. The locking member 230 is a pin. The locking member 230 passes through the pin hole and is inserted into the positioning hole. The first rotating shaft 220 is provided with a scale along the circumference. The scale is marked with the rotation angle. Each scale on the scale corresponds to each positioning hole.
[0030] The working principle of this embodiment is as follows:
[0031] This utility model discloses a pipe clamping device. Before machining the indexing hole of the pipe, one end of the pipe is fixed by a first fixing mechanism 300, and the other end of the pipe is fixed by a second fixing mechanism 400, so that the pipe is firmly fixed. Then, the pipe can be drilled manually or by drilling equipment. After drilling a hole, the first rotating mechanism 200 can be manually rotated, thereby driving the pipe fixed on the first fixing mechanism 300 to rotate. When the pipe rotates to the appropriate position, the locking member 230 is inserted into the corresponding positioning hole, thereby locking the first rotating shaft 220 and restricting the rotation of the first rotating shaft 220. Then, the pipe is machined for the next indexing hole. The operator can determine the position of the positioning hole by observing the scale on the first rotating shaft 220.
[0032] The beneficial effects of this embodiment are as follows:
[0033] Compared to existing technologies, this device uses a locking element 230 to lock the rotation of the first rotating shaft 220, eliminating the need for manual control during drilling, resulting in better stability and drilling performance. Manual control of the first rotating shaft 220 allows for free adjustment of the drilling position compared to electric control, offering better adjustability. The handwheel 211 serves as a grip 210, allowing operators to adjust the drilling position of the pipe fitting by rotating the handwheel 211, making operation convenient and labor-saving. The use of a pin as the locking element 230 facilitates easy assembly and disassembly.
[0034] In addition, the locking element 230 can also be a bolt. By tightening the bolt, one end of the bolt presses against the first rotating shaft 220, thereby restricting the rotation of the first rotating shaft 220.
[0035] Example 2
[0036] This embodiment is a second embodiment of a pipe clamping device, such as... Figures 2-4 As shown, the first fixing mechanism 300 is a chuck 310, and three jaws 311 are evenly arranged on the circumference of the chuck 310. The jaws 311 are used to support the inner wall of the pipe fitting. The second fixing mechanism 400 includes a second rotating shaft 410 and a top pipe fitting 420 connected to the output end of the second rotating shaft 410. The top pipe fitting 420 is tapered, and the maximum outer diameter of the top pipe fitting 420 is greater than the inner diameter of the pipe fitting. The axis of the top pipe fitting 420 and the axis of the second rotating shaft 410 are both collinear with the axis of the pipe fitting. The end of the top pipe fitting 420 with the larger outer diameter is connected to the second rotating shaft 410.
[0037] The working principle of this embodiment is as follows:
[0038] By turning the square hole on the chuck 310, the jaws 311 can be controlled to move synchronously closer to or further away from its axis. When installing the pipe fitting, by adjusting the jaws 311 to move away from its axis, the jaws 311 press against the inner wall of the pipe fitting, thereby fixing the pipe fitting. When removing the pipe fitting, turn the square hole in the opposite direction to release the jaws 311, thereby removing the pipe fitting. After installing one end of the pipe fitting on the first fixing mechanism 300, the top pipe fitting 420 is inserted into the inside of the pipe fitting. Since the maximum outer diameter of the top pipe fitting 420 is larger than the inner diameter of the pipe fitting, the top pipe fitting 420 can apply an axial thrust to one end of the pipe fitting, thus tightening the pipe fitting.
[0039] The beneficial effects of this embodiment are as follows:
[0040] By using the chuck 310 as the first fixing mechanism 300, the radial fixing of the pipe fitting is better achieved. The setting of the top pipe fitting 420 further improves the axial fixing of the pipe fitting, ensuring the stability of the pipe fitting during drilling. The top pipe fitting 420 is tapered, which can accommodate pipe fittings with more inner diameters, thus improving its applicability.
[0041] The remaining working principles of this embodiment are the same as those of Embodiment 1.
[0042] In addition, the chuck 310 can also clamp the outer wall of the pipe fitting from the outside in, but the installation of the pipe fitting is not as convenient as the above method.
[0043] Example 3
[0044] This embodiment is a third embodiment of a pipe clamping device. This embodiment is similar to embodiment one, except that, as shown in the example... Figure 2 and Figure 3As shown, the top of the base 100 is provided with two guide rails 130 parallel to the axis of the first rotating shaft 220. The first shaft seat 110 and the second shaft seat 120 are both slidably connected to the two guide rails 130. The first shaft seat 110 and the guide rails 130 are fixed together by fasteners, and the second shaft seat 120 and the guide rails 130 are fixed together by fasteners. In this embodiment, the fasteners are bolts, but they can also be detachable connection methods such as pins and buckles.
[0045] The working principle of this embodiment is as follows:
[0046] The second shaft seat 120 is slid to push the top pipe fitting 420 into the inside of the pipe, and then the second shaft seat 120 is fixed to the guide rail 130 by fasteners, thereby fixing the pipe fitting in the axial direction. In addition, the distance between the first shaft seat 110 and the second shaft seat 120 can be adjusted to accommodate pipe fittings of different lengths, thus improving applicability. The fasteners enable quick locking and unlocking, improving convenience. The design of the guide rail 130 makes the sliding stability of the first shaft seat 110 and the second shaft seat 120 better.
[0047] The remaining working principles of this embodiment are the same as those of Embodiment 1.
[0048] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make various variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
