Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning pipe processing, and in particular to a force-enhancing dotting mechanism for air-conditioning pipes. Background Art

[0002] Currently, marking air conditioning pipes during production and assembly is crucial to ensuring accurate and reliable connections. As the application of air conditioning pipes continues to expand, the requirements for marking are becoming increasingly stringent, particularly in terms of accuracy and reliability. As a key component connecting various components, the quality of marking directly impacts the performance and service life of the entire system.

[0003] In the existing technology, in order to solve the problem of dotting and marking of air-conditioning pipes, two groups of cylinders are usually used to work together. Generally, a dotting head is installed at the end of the cylinder. When the dotting operation is required, the operator places the air-conditioning pipe between the two groups of cylinders, and the telescopic action of the cylinder drives the dotting head to squeeze the two ends of the air-conditioning pipe, thereby achieving the dotting purpose.

[0004] However, in actual operation, the method of using two sets of cylinders to operate synchronously has the defect of being difficult to ensure the consistency of cylinder movement during actual use, resulting in unstable dotting accuracy and affecting the final dotting quality. At the same time, this method will also increase the cost and size of the equipment, reducing its practicality and flexibility in the production line.

[0005] In view of the above problems, a force-enhancing and dotting mechanism for air-conditioning pipes is now designed. Utility Model Content

[0006] An embodiment of the present application provides a force-boosting dotting mechanism for air-conditioning pipes to solve the problem that the related technology uses two groups of cylinders to operate synchronously for dotting operations, which easily leads to unstable dotting accuracy and affects the dotting quality of the air-conditioning pipes. At the same time, it also increases the cost and volume of the equipment and reduces its practicality and flexibility in the production line.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] An embodiment of the present application provides a force-boosting dotting mechanism for air-conditioning pipes, which can solve the problem in the related art of using two groups of cylinders to perform dotting operations synchronously, which easily leads to unstable dotting accuracy and affects the dotting quality of the air-conditioning pipes. At the same time, it also increases the cost and volume of the equipment, which reduces its practicality and flexibility in the production line.

[0027] See also Figure 1-Figure 3A force-enhancing dotting mechanism for an air-conditioning pipe comprises: a fixing frame 1, a core rod 2, a connecting block 3, an extrusion assembly 4, and a driving assembly 5. The core rod 2 is arranged on the fixing frame 1, the connecting block 3 is arranged below the core rod 2, and the extrusion assembly 4 is provided with two groups, which are symmetrically arranged on both sides of the core rod 2. The extrusion assembly 4 comprises a slider 41, a fixing column 42, a first connecting rod 43, a second connecting rod 44, a first connecting shaft 45, and a second connecting shaft 46.

[0028] The slider 41 is slidably arranged on the fixed frame 1, and the slider 41 is located on one side of the core rod 2. The fixed column 42 is arranged on the side of the slider 41 close to the core rod 2, and the first connecting rod 43 is arranged on the side of the slider 41 away from the fixed column 42. A limiting hole 47 is provided at one end of the first connecting rod 43 close to the slider 41, and the first connecting shaft 45 passes through the slider 41 and the limiting hole 47 and is rotatably connected to the slider 41. The second connecting shaft 46 passes through the fixed frame 1 and the first connecting rod 43 and is rotatably connected to the fixed frame 1. The second connecting rod 44 is rotatably arranged at the lower end of the first connecting rod 43, and the end of the second connecting rod 44 away from the first connecting rod 43 is rotatably connected to the connecting block 3. The driving assembly 5 is provided on the fixed frame 1 and connected to the connecting block 3 to drive the connecting block 3 to move closer to or away from the core rod 2;

[0029] Specifically, in this embodiment, the driving assembly 5 includes a cylinder, which is provided on the fixing frame 1, and the output end of the cylinder is fixedly connected to the connecting block 3;

[0030] In this way, when in use, the staff can put the air-conditioning pipe sleeve on the core rod 2, and then push the connecting block 3 toward the core rod 2 through the cylinder, so that the connecting block 3 will simultaneously push the two groups of first connecting rods 43 to move through the two groups of second connecting rods 44. At the same time, through the limiting effect of the second connecting shaft 46 and the first connecting rod 43 being rotatably connected, the first connecting rod 43 will rotate and push the first connecting shaft 45 to move toward the core rod 2. Then, the two groups of first connecting shafts 45 will push the fixed column 42 on the slider 41 to move toward the core rod 2 through the rotation connection with the two groups of sliders 41. At the same time, the limiting hole 47 allows the first connecting shaft 45 to move in the limiting hole 47 in the process of pushing the slider 41 to move, thereby avoiding the first connecting shaft 45 and the first connecting rod 43 from getting stuck during the transmission process;

[0031] In this way, the two sets of fixing columns 42 can be brought close to each other at the same time and squeeze the air-conditioning pipe, thereby marking both sides of the air-conditioning pipe, and the core rod 2 is used to position and support the air-conditioning pipe to avoid displacement of the air-conditioning pipe during the marking process, and to avoid extrusion and deformation of the air-conditioning pipe. Conversely, the cylinder pushes the connecting block 3 away from the core rod 2 to reset, so that the connecting block 3 will pull the slider 41 away from the core rod 2 through the cooperative transmission of the second connecting rod 44 and the first connecting rod 43, thereby moving the two sets of fixing columns 42 away from each other to facilitate the removal of the air-conditioning pipe. Then the staff can put a new air-conditioning pipe on the core rod 2, and then make the two sets of fixing columns 42 close to each other to squeeze and mark the air-conditioning pipe. The air-conditioning pipe can be marked repeatedly by repeating this cycle.

[0032] In this way, through the coordinated transmission of two sets of symmetrically arranged connecting rod mechanisms and a single cylinder, not only can the movements of the two sets of fixed columns 42 be linked to ensure the consistency of the movements of the two sets of fixed columns 42, thereby ensuring the accuracy of the marking of the air-conditioning pipes and the quality of the marking of the air-conditioning pipes, but the device has a simple structure and is easy to inspect and maintain. There is no need to use two sets of driving parts, and only one cylinder is needed. This not only reduces the cost of the equipment, but also reduces the size of the equipment. It is highly flexible, easy to install and use, and has strong practicality.

[0033] More specifically, the distance between the second connecting shaft 46 and the first connecting shaft 45 is smaller than the distance between the second connecting shaft 46 and the second connecting rod 44;

[0034] In this way, the force of the cylinder push can be amplified through the lever principle, so that one cylinder can achieve a stronger extrusion effect, which plays a role in enhancing the thrust of the slider 41. This not only ensures the quality of the air-conditioning pipe, but also avoids the cylinder from running at high intensity for a long time, thereby ensuring the service life of the cylinder and facilitating use.

[0035] Preferably, a guide post 6 is provided at one end of the connecting block 3 close to the core rod 2, and the guide post 6 passes through the fixing frame 1 and is slidably connected thereto;

[0036] In this way, the guide column 6 can play a guiding and stabilizing role in the process of the cylinder driving the connecting block 3 to move up and down, avoiding inaccurate hitting due to the shaking of the cylinder, and at the same time preventing the cylinder from tilting during the extension and retraction process, affecting the service life of the cylinder.

[0037] Furthermore, in this embodiment, two sets of dovetail grooves 11 are provided on the fixing frame 1, and the two sets of dovetail grooves 11 are symmetrically arranged on both sides of the core rod 2;

[0038] The slider 41 includes a slider body 411 and a wedge block 412 . The wedge block 412 is slidably disposed in the dovetail groove 11 , and the slider body 411 is disposed on the wedge block 412 .

[0039] In this way, the fixed column 42 can be guided and limited by the limiting guiding effect of the sliding connection between the wedge block 412 and the dovetail groove 11, so that the two groups of fixed columns 42 can only move towards or away from each other along a straight line, thereby avoiding the fixed column 42 from deviating during the movement and affecting the quality of the air-conditioning pipe. It is highly practical.

[0040] The top of the core rod 2 is rounded.

[0041] This can serve as a guide for the staff when they are sleeved with the air-conditioning pipe, thereby facilitating the staff to sleeve the air-conditioning pipe onto the core rod 2 and facilitating use.
