Description

Technical Field

[0001] This application relates to the field of dotting device technology, and in particular to an air conditioning pipe boosting dotting device. Background Technology

[0002] In a central air conditioning system, the air conditioning branch pipe plays a role in distributing refrigerant from the main unit to each indoor unit, thereby ensuring that each room receives adequate cooling. Air conditioning branch pipes are typically made of welded copper tubing. During the welding process, two welding positioning points are usually made in the welding area to improve welding precision and reduce welding difficulty.

[0003] Currently, when welding positioning points on air conditioning pipes, the pipes need to be fixed first. Then, two cylinders located on either side of the pipe drive a pressure head to press against the pipe, thus creating two welding positioning points. While this method of using two cylinders to drive a pressure head can achieve the two welding positioning points, the design of two cylinders not only increases costs but also results in inconsistent processing of the two positioning points, potentially affecting the welding quality. Utility Model Content

[0004] In order to improve the design of the two cylinders, which not only increases the cost, but also causes the two welding positioning points to have poor consistency in processing, which easily affects the welding quality, this application provides an air conditioning pipe force boosting marking device.

[0005] The air conditioning pipe boosting and marking device provided in this application adopts the following technical solution:

[0006] An air conditioning pipe force-boosting device includes a mounting base, a positioning rod, a first slider, a second slider, and a driving mechanism. The positioning rod is mounted on the mounting base. The first slider and the second slider are both slidably connected to the mounting base. The first slider and the second slider are located on opposite sides of the positioning rod. Each of the first slider and the second slider has a pressure head on the side closest to each other. The driving mechanism is mounted on the mounting base and is used to synchronously drive the first slider and the second slider to move closer to each other or further apart.

[0007] By adopting the above technical solution, during use, one end of the air conditioning pipe to be marked is fitted onto the positioning rod to form a preliminary position. Then, the first and second sliders are driven to move closer together by the drive mechanism. As the first and second sliders move closer together, the pressing heads on them gradually press against the outer peripheral wall of the air conditioning pipe. As the pressing heads press against the air conditioning pipe, a recessed point is formed on the peripheral wall of the air conditioning pipe corresponding to the position of the pressing head, thus completing the marking operation on the air conditioning pipe. The marking operation of two points on the air conditioning pipe is completed by one drive mechanism. Improving the design of two cylinders not only increases the cost, but also causes the problem of poor consistency in the processing of the two welding positioning points, which easily affects the welding quality.

[0008] Optionally, the driving mechanism includes a linear drive, a third slider, and two sets of connecting assemblies. The third slider is slidably connected to the mounting base along the length of the positioning rod. The linear drive is mounted on the mounting base, and its output end is connected to the third slider. The connecting assemblies include a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the third slider, and the other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The middle part of the second connecting rod is rotatably connected to the mounting base via a rotating rod. In one of the connecting assemblies, the other end of the second connecting rod is rotatably connected to the first slider, and in the other connecting assembly, the other end of the second connecting rod is rotatably connected to the second slider.

[0009] By adopting the above technical solution, the third slider is moved using a linear drive component, thereby transmitting the motion to the first and second sliders via a connecting assembly. Specifically, the movement of the third slider, through the linkage of the first and second connecting rods, enables the first and second sliders to move synchronously in opposite directions, thus precisely adjusting their relative positions and ensuring a uniform force is applied to the air conditioning pipe. This design not only simplifies the structural complexity but also improves operational efficiency and stability.

[0010] Optionally, the distance from the rotating rod to the end of the second connecting rod near the third slider is greater than the distance to the other end.

[0011] By adopting the above technical solution, the second link can generate a greater leverage effect when driven by the third slider, thereby reducing the force or energy consumption required for driving. Specifically, the design of the lever position increases the lever arm length, which can more effectively push the first and second sliders to move under the same input force, improving the working efficiency of the entire drive mechanism and reducing energy consumption.

[0012] Optionally, a sliding groove is provided on the peripheral wall of the positioning rod, and two fourth sliders are slidably connected in the sliding groove. One end of the fourth slider protruding from the sliding groove is provided with an arc-shaped block, and the positioning rod is provided with a power component for synchronously driving the two fourth sliders to move closer or further apart.

[0013] By adopting the above technical solution, the sliding groove on the periphery of the positioning rod provides a stable sliding path for the fourth slider, enabling the two fourth sliders to move along the extension direction of the sliding groove. The arc-shaped block set at one end of the fourth slider protruding from the sliding groove can better adapt to the inner diameter of the air conditioning pipe. During the process of the arc-shaped block pressing against the inner diameter of the air conditioning pipe, it provides a larger contact area and a more uniform force, thereby improving the fixing effect of the air conditioning pipe and thus improving the accuracy of the marking. In addition, the adjustable distance between the two arc-shaped blocks also allows it to adapt to air conditioning pipes with different inner diameters, improving the adaptability to fixing air conditioning pipes with different inner diameters. At the same time, the introduction of the power component enables synchronous driving of the two fourth sliders, ensuring that their movements are coordinated and consistent, further improving the operating efficiency and stability.

[0014] Optionally, the power assembly includes a fifth slider, a limiting block, and a power component. A through hole is coaxially formed on the positioning rod, and the fifth slider is slidably inserted into the through hole. A slope is formed at one end of the fourth slider near the axis of the positioning rod, and the distance from the slope to the axis of the positioning rod gradually decreases along the axis of the positioning rod. A groove is formed on the slope. Two limiting blocks are provided on the fifth slider, and the ends of each limiting block away from the fifth slider are slidably engaged in the grooves of the two fourth sliders. The power component is provided on the positioning rod and is used to drive the fifth slider to slide.

[0015] By adopting the above technical solution, precise control of the two fourth sliders can be achieved. Specifically, the sliding of the fifth slider within the through hole causes the limiting block to move along the inclined plane, thereby pushing the fourth sliders closer together or further apart, ensuring the synchronization and stability of the movements. This design allows the arc-shaped block on the positioning rod to be precisely adjusted to adapt to different size requirements, improving the versatility of the device. Simultaneously, by utilizing the cooperation of the inclined plane and the slide groove, linear motion is converted into radial motion of the fifth slider, simplifying the structure and improving transmission efficiency.

[0016] Optionally, the power component includes a threaded rod and a rotating sleeve. The threaded rod is movably inserted into the through hole, and one end of the threaded rod inserted into the through hole is connected to the fifth slider. The rotating sleeve is rotatably connected to the positioning rod around the positioning rod axis, and the threaded rod passes through the rotating sleeve and is threadedly connected to the rotating sleeve.

[0017] By adopting the above technical solution, precise control of the fifth slider by the power component is achieved. Specifically, the cooperation between the threaded rod and the rotating sleeve converts the rotational motion of the rotating sleeve into the linear motion of the fifth slider along the length of the threaded rod, thereby driving the fifth slider to move stably within the through hole. This design not only improves transmission efficiency but also ensures the synchronization and stability of the two fourth sliders, further enhancing the overall performance of the device. The threaded connection design makes operation more convenient and provides good self-locking properties, effectively preventing accidental loosening.

[0018] Optionally, the positioning rod is provided with a clearance groove corresponding to each pressing head.

[0019] By adopting the above technical solution, the setting of the clearance groove can effectively avoid the interference problem between the positioning rod and the pressing head, ensuring that the pressing head can smoothly complete the marking of the outer peripheral wall of the air conditioning pipe during the movement of the first slider and the second slider, thereby improving the operational reliability and applicability of the device; and this design enables the branching device to work stably in a narrow space, improving the compactness and practicality of the overall structure.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The coordinated arrangement of the mounting base, positioning rod, first slider, second slider and drive mechanism can position the air conditioning pipe that needs to be marked. Then, the drive mechanism drives the first slider and the second slider to move closer synchronously, so that the pressure heads on the first slider and the second slider can simultaneously perform the marking operation on the air conditioning pipe. Improving the design of the two cylinders not only increases the cost, but also has the problem that the consistency of the processing of the two welding positioning points is not good, which can easily affect the welding quality.

[0022] 2. The matching arrangement of the linear drive component, the third slider, the first link, and the second link enables the linear drive component to move the third slider. Through the linkage of the first link and the second link, the first slider and the second slider can move synchronously in opposite directions or in opposite directions, thereby accurately adjusting their relative positions, ensuring that a uniform force is applied to the air conditioning pipe, improving the consistency of the marking, and thus improving the marking quality.

[0023] 3. The design of the lever position increases the lever arm length, which can more effectively push the first and second sliders to move under the same input force, thereby improving the working efficiency of the entire drive mechanism and reducing energy consumption.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses an air conditioning pipe boosting and marking device. (Refer to...) Figure 1-2 The air conditioning pipe booster device includes a mounting base 1, a positioning rod 2, a first slider 3, a second slider 4, and a drive mechanism 5. The mounting base 1 has a horizontal mounting hole 11 on one side. The positioning rod 2 is inserted into the mounting hole 11 on the mounting base 1. A locking pin 12 is inserted into the mounting base 1, and the locking pin 12 abuts against the periphery of the positioning rod 2 to lock it. The first slider 3 and the second slider 4 are both slidably connected to the mounting base 1, and are located on opposite sides of the positioning rod 2. A pressure head 6 is fixedly installed on the side of the first slider 3 and the second slider 4 that is closer to each other. The drive mechanism 5 is mounted on the mounting base 1 and is used to synchronously drive the first slider 3 and the second slider 4 to move closer or further apart.

[0031] In use, the air conditioning pipe to be marked is first positioned on the positioning rod 2. Then, the first slider 3 and the second slider 4 are driven to move closer to each other by the driving mechanism 5 until the pressing head 6 on the first slider 3 and the second slider 4 presses against the outer peripheral wall of the air conditioning pipe. As the pressing head continues to move closer, it can press a recessed point on the peripheral wall of the air conditioning pipe at the position corresponding to the pressing head 6. The marking operation on both sides of the air conditioning pipe can be completed simultaneously. Compared with the marking operation on both sides of the air conditioning pipe by using two cylinders to complete the marking operation separately, the device of this application can complete the operation simultaneously by only one driving mechanism 5. Improving the design of two cylinders not only increases the cost, but also causes the problem of poor consistency in the processing of the two welding positioning points, which can easily affect the welding quality.

[0032] Specifically, the mounting base 1, as the basic component of the entire device, is made of high-strength steel to ensure sufficient load-bearing capacity and durability. The positioning rod 2 can be made of stainless steel to enhance its compressive strength and wear resistance. Regarding the design of the first slider 3 and the second slider 4, they are made of aluminum alloy, which is lightweight and has good wear resistance. Each of these components has a ball bearing track embedded inside to reduce the coefficient of friction, thus making the sliding smoother.

[0033] For example, the core components of the drive mechanism 5 include a linear drive component 51, a third slider 52, and two sets of connecting assemblies. A rod 53 is integrally formed on one side of the third slider 52. The diameter of the rod 53 is adapted to the inner diameter of the mounting through hole 11, and the rod 53 is movably inserted into the mounting through hole 11. As an intermediate transmission medium, the third slider 52 needs to possess excellent rigidity and stability. In this application, it is made of carbon steel, and a lubricating coating is processed on the outer side to reduce the probability of wear and extend its service life. The linear drive component 51 is a cylinder in this application. The linear drive component 51 is fixedly mounted on the mounting base 1, and its output end is fixedly connected to the third slider 52.

[0034] Two sets of connecting components are symmetrically arranged on the mounting base 1 around the axis of the positioning rod 2. Each connecting component includes a first connecting rod 54 and a second connecting rod 55. One end of the first connecting rod 54 is rotatably connected to the third slider 52, and the other end of the first connecting rod 54 is rotatably connected to one end of the second connecting rod 55. A rotating rod 56 is vertically inserted through the middle of the second connecting rod 55, and the rotating rod 56 is fixedly mounted on the mounting base 1, allowing the second connecting rod 55 to be rotatably connected to the mounting base 1 around the lower part of the rotating rod 56. In one of the connecting components, the other end of the second connecting rod 55 is rotatably connected to the first slider 3, and in the other connecting component, the other end of the second connecting rod 55 is rotatably connected to the second slider 4.

[0035] When the linear drive unit 51 is activated, the driving force generated will be transmitted to the third slider 52, causing the third slider 52 to displace, which will drive the first connecting rod 54 to swing, and then drive the second connecting rod 55 to rotate around the axis of the rotating rod 56, thereby causing the first slider 3 and the second slider 4 to move closer to or further away from each other in sync.

[0036] Furthermore, the distance from the rotating rod 56 to the end of the second connecting rod 55 near the third slider 52 is greater than the distance to the other end. The design of the rotating rod 56 increases the lever arm length, which can more effectively push the first slider 3 and the second slider 4 to move under the same input force, improve the working efficiency of the entire drive mechanism 5 and reduce energy consumption, so that the device can provide greater pressure for the marking of the air conditioning pipe and improve the marking efficiency.

[0037] Furthermore, the positioning rod 2 is provided with a relief groove 21 corresponding to each pressing head 6. The relief groove 21 can effectively avoid the interference problem between the positioning rod 2 and the pressing head 6, and ensure that the pressing head 6 can smoothly complete the marking of the outer peripheral wall of the air conditioning pipe during the movement of the first slider 3 and the second slider 4, thereby improving the operational reliability and applicability of the device.

[0038] In addition, refer to Figure 3 The positioning rod 2 has a sliding groove 22 on its circumferential wall. Two fourth sliders 7 are slidably connected within the sliding groove 22. Each fourth slider 7 has an arc-shaped block 71 at one end protruding from the sliding groove 22, which abuts against the inner wall of the air conditioning pipe. The positioning rod 2 also has a power assembly 8, which synchronously drives the two fourth sliders 7 to move closer or further apart. By driving the two fourth sliders 7 closer or further apart via the power assembly 8, the positioning rod 2 can change its outer diameter, thus adapting to the positioning of air conditioning pipes with different inner diameters, making it more adaptable.

[0039] Specifically, the power assembly 8 includes a fifth slider 81, a limiting block 82, and a power component. A through hole 23 is coaxially formed on the positioning rod 2, and the fifth slider 81 is slidably inserted into this hole. A slope 72 is formed at the end of the fourth slider 7 closest to the axis of the positioning rod 2. The distance from the slope 72 to the axis of the positioning rod 2 gradually decreases along the axis of the positioning rod 2. A groove 73 is formed on the slope 72. Two limiting blocks 82 are disposed on the fifth slider 81, and the ends of each limiting block 82 away from the fifth slider 81 are slidably engaged within the grooves 73 of the two fourth sliders 7. The power component is disposed on the positioning rod 2 and is used to drive the fifth slider 81 to slide. The power component drives the fifth slider 81 to slide within the through hole 23, causing the limiting block 82 to move along the grooves 73 on the slope 72 of the fourth slider 7, thereby pushing the two fourth sliders 7 closer together or further apart.

[0040] Furthermore, the power component includes a threaded rod 83 and a rotating sleeve 84. The threaded rod 83 is movably inserted into the through hole 23, with one end inserted into the through hole 23 welded and fixed to the fifth slider 81. The rotating sleeve 84 is rotatably connected to the positioning rod 2 around its axis. The threaded rod 83 passes through the rotating sleeve 84 and is threadedly connected to it. By rotating the rotating sleeve 84, the threaded rod 83 tends to rotate with the rotating sleeve 84. Since the threaded rod 83 is welded to the fifth slider 81 and cannot rotate, rotating the rotating sleeve 84 can drive the threaded rod 83 to move along its own axis, thereby achieving the driving function of the fifth slider. The threaded connection design makes operation more convenient and also has good self-locking properties, effectively preventing accidental loosening.

[0041] The implementation principle of the air conditioning pipe force-enhancing marking device in this application embodiment is as follows: During use, the rotating sleeve 84 is rotated appropriately according to the inner diameter of the air conditioning pipe, which drives the threaded rod 83 to move, thereby driving the fifth slider 81, and then driving the limiting block 82 to move along the inclined plane 72, thereby pushing the fourth slider 7 to move closer or further apart, thus driving the arc plate on the fourth slider 7 to press against the inner wall of the air conditioning pipe, achieving stable positioning of the air conditioning pipe. Then, the linear drive member 51 drives the third slider 52 to move, driving the first connecting rod 54 to swing, and then driving the second connecting rod 55 to rotate around the axis of the rotating rod 56, thereby driving the first slider 3 and the second slider 4 to move closer synchronously, until the pressing head 6 on the first slider 3 and the second slider 4 presses against the outer peripheral wall of the air conditioning pipe, realizing the synchronous marking operation of two points on the air conditioning pipe. The device of this application can complete the marking of two points on the air conditioning pipe synchronously with only one linear drive member 51, which improves the design of two cylinders, not only increasing the cost, but also solving the problem of poor consistency in the processing of the two welding positioning points, which easily affects the welding quality.

[0042] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
