Description

Technical Field

[0001] This utility model relates to the field of automation, and in particular to an automatic sleeve changing device. Background Technology

[0002] With the widespread adoption of automated or semi-automated assembly processes, the automatic screw tightening process in the production line of thermal management integrated modules for new energy vehicles inevitably involves a single station requiring the tightening of two or more types of screws. Examples include the valve core and coil of an electronic expansion valve (EXV) and the valve core and coil of a high-pressure shut-off valve (SOV). Since the two types of valve cores and coils are different, at least three types of sockets are needed to match them. Using multiple tightening guns would significantly increase costs and the probability of errors. This invention solves the problem of using one tightening gun to handle multiple sockets or bits, effectively preventing errors. Utility Model Content

[0003] The purpose of this invention is to provide an automatic sleeve changing device to solve the problem of sleeve replacement mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic sleeve changing device includes a base plate, on the upper surface of which a bracket and a mounting plate are provided. A processing component one is provided on the upper part of the bracket facing the mounting plate. A moving component is provided inside the mounting plate. Several sets of processing components two are provided on the moving component. The processing components two cooperate with the processing component one.

[0005] Preferably, the processing component one includes an electric telescopic rod one, the fixed end of the electric telescopic rod one is connected to the bracket, the extended end of the electric telescopic rod one is provided with a push plate, the push plate is provided with a clamping component one, and an electric tightening gun is provided through the push plate. The electric tightening gun is detachably connected to the push plate through the clamping component one.

[0006] Preferably, the clamping assembly includes a connecting plate, which is connected to a push plate. A guide rod is slidably mounted on the connecting plate, and a clamping block is provided on the side of the guide rod near the electric tightening gun. The clamping block is connected to the connecting plate by a spring.

[0007] Preferably, the moving component includes a threaded motor connected to a mounting plate. The drive end of the threaded motor is provided with a threaded shaft, and a threaded slider is provided on the threaded shaft. A connecting plate is provided on the side of the threaded slider away from the mounting plate, and the side of the connecting plate away from the threaded slider is connected to several sets of processing components.

[0008] Preferably, the processing component two includes several sets of electric telescopic rods two. The side of the electric telescopic rod two is connected to the connecting plate two. The extended end of the electric telescopic rod two is provided with a connecting plate three. The side of the connecting plate three is provided with a connecting plate four and a limiting plate arranged vertically. The connecting plate four is located at the lower part of the connecting plate three. The limiting plate is located at the middle part of the connecting plate three. The connecting plate four is provided with a clamping component two. The clamping component two is located between the connecting plate four and the limiting plate.

[0009] Preferably, the clamping assembly 2 includes a moving motor, which is connected to the connecting plate 4. The driving end of the moving motor is provided with a threaded screw, and two sets of threaded sliders 2 that move apart or toward each other are sleeved on the threaded screw. A clamping block 2 is provided on the side of the threaded sliders 2 away from the connecting plate 3.

[0010] The beneficial effects of this utility model are: 1. When the threaded motor starts, it drives the threaded shaft to rotate, which in turn drives the connecting plate two and the processing component two to move the different sleeves they hold. This allows the sleeves to be moved to the electric tightening gun, ensuring that different types of sleeves can be selected and replaced as needed. It also enables the classification of sleeves, thereby reducing the probability of errors.

[0011] 2. The moving motor in clamping assembly two is started, which drives the threaded screw to rotate, causing the threaded slider two and clamping block two to move towards each other. This clamps sleeves of different sizes and models, and ensures that the upper part of the sleeve is installed horizontally with the electric tightening gun, thereby ensuring the flatness and practicality of the subsequent pin docking.

[0012] 3. Furthermore, when the guide rod is pulled, causing the clamping block to move away from the electric tightening gun, the spring begins to compress, thus allowing the electric tightening gun to be easily removed. The installation principle is the same, thereby achieving the effect of quick replacement and disassembly of the electric tightening gun. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-7 This utility model provides an automatic sleeve changing device, including a base plate 1. A bracket 2 and a mounting plate 3 are provided on the upper surface of the base plate 1. A processing component 4 is provided on the upper part of the bracket 2 facing the mounting plate 3. A moving component 5 is provided inside the mounting plate 3. Several sets of processing components 6 are provided on the moving component 5. The processing components 6 cooperate with the processing components 4. By placing sleeves of different sizes into the processing components 6 for clamping, and through the cooperation of the processing components 6 and the processing components 4, the sleeves are installed.

[0017] See Figures 1-3 Specifically, the processing component 4 includes an electric telescopic rod 41. The fixed end of the electric telescopic rod 41 is connected to the bracket 2. The extended end of the electric telescopic rod 41 is provided with a push plate 42. The push plate 42 is provided with a clamping component 43. An electric tightening gun 44 is inserted through the push plate 42. The electric tightening gun 44 is detachably connected to the push plate 42 through the clamping component 43. By adjusting the clamping component 43, the electric tightening gun 44 can be quickly replaced, and by adjusting the extension and retraction of the electric telescopic rod 41, the moving position of the electric tightening gun 44 can be controlled.

[0018] See Figures 3-4Specifically, the clamping assembly 43 includes a connecting plate 431 connected to a push plate 42. A guide rod 432 is slidably mounted on the connecting plate 431. A clamping block 433 is located on the side of the guide rod 432 near the electric tightening gun 44. The clamping block 433 is connected to the connecting plate 431 via a spring 434. When the guide rod 432 is pulled, the clamping block 433 is moved away from the electric tightening gun 44. At this time, the spring 434 begins to compress, thus allowing the electric tightening gun 44 to be easily removed. The installation principle is the same, thereby achieving the effect of quick replacement of the electric tightening gun 44.

[0019] See Figures 3-5 Specifically, the moving component 5 includes a threaded motor 51 connected to the mounting plate 3. The drive end of the threaded motor 51 has a threaded shaft 52, and the threaded shaft 52 has a threaded slider 53. A connecting plate 54 is located on the side of the threaded slider 53 away from the mounting plate 3. The side of the connecting plate 54 away from the threaded slider 53 is connected to several sets of processing components 6. When the threaded motor 51 starts, it drives the threaded shaft 52 to rotate, causing the connecting plate 54 and the processing components 6 to move while holding different sleeves, thereby adjusting the position of the required sleeve below the electric tightening gun 44.

[0020] See Figures 3-7 Specifically, the processing component 2 6 includes several sets of electric telescopic rods 2 62. The side of each electric telescopic rod 2 62 is connected to a connecting plate 2 54. The extended end of each electric telescopic rod 2 62 is provided with a connecting plate 3 63. The side of the connecting plate 3 63 is provided with a connecting plate 4 64 and a limiting plate 65 arranged vertically. The connecting plate 4 64 is located at the lower part of the connecting plate 3 63, and the limiting plate 65 is located at the middle part of the connecting plate 3 63. A clamping component 2 66 is provided on the connecting plate 4 64, and the clamping component 2 66 is located between the connecting plate 4 64 and the limiting plate 65. When the electric telescopic rods 2 62 in the processing component 2 6 begin to extend, they drive the connecting plate 3 63, the connecting plate 4 64, the limiting plate 65, and the clamped sleeve to move upward, ensuring that the sleeve contacts the electric tightening gun 44.

[0021] See Figure 7 Specifically, the clamping assembly 2 66 includes a moving motor 661 connected to the connecting plate 4 64. The driving end of the moving motor 661 is provided with a threaded screw 662. Two sets of threaded sliders 2 663, which move apart or in opposite directions, are sleeved on the threaded screw 662. A clamping block 2 664 is provided on the side of the threaded sliders 2 663 away from the connecting plate 3 63. Starting the moving motor 661 in the clamping assembly 2 66 causes the threaded screw 662 to rotate, causing the threaded sliders 2 663 to move apart from the clamping block 2 664, thus releasing the sleeve.

[0022] Working principle of this utility model: In use, the sleeve is placed into the limiting plate 65, with its bottom contacting the connecting plate 64. At this time, the moving motor 661 in the clamping assembly 66 starts, driving the threaded screw 662 to rotate. This causes the threaded slider 663 and the clamping block 664 to move towards each other, clamping sleeves of different sizes. Then, depending on the sleeve to be used, the threaded motor 51 is started, driving the threaded shaft 52 to rotate. This causes the connecting plate 54 and the processing assembly 6 to move, clamping different sleeves. This adjusts the position of the sleeve to be used, moving it directly below the electric tightening gun 44. The electric telescopic rod 62, located directly below the electric tightening gun 44, begins to extend, causing the connecting plate 63, connecting plate 64, limiting plate 65, and the clamped sleeve to move upward, ensuring that the sleeve contacts the electric tightening gun 44. The electric tightening gun 44 then rotates slowly to allow the sleeve to smoothly engage with the locking pin of the electric tightening gun 44.

[0023] During disassembly, after the screws corresponding to the sleeve are tightened, the electric tightening gun 44, along with the sleeve, is placed in the replacement position manually or by a robotic arm. At this point, the moving motor 661 starts, driving the threaded screw 662 to rotate. This causes the threaded slider 663 and clamping block 664 to move towards each other, clamping the sleeve. The sleeve is pulled away from the tightening gun, and the electric telescopic rod 62 retracts, causing the connecting plate 63, connecting plate 64, and limiting plate 65 to reset, along with the clamped sleeve. The left-right moving mechanism moves the sleeve to the next position according to a pre-set program, repeating the above actions to complete the sleeve replacement.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
