[0038] The present invention provides a positioning device 100 for an air-conditioning compressor. Figures 1 to 3 This is an embodiment of the positioning device 100 for an air-conditioning compressor provided by the present invention.

[0039] Please also refer to Figures 1 to 3The positioning device 100 of the air-conditioning compressor includes a supporting structure 1, a translation structure 4 and a lifting structure 5, wherein the supporting structure 1 includes a supporting platform 12 and two supporting members 11, and two supporting members 11 are arranged at intervals on the top of the supporting platform 12 along the first horizontal direction, wherein the top surface of one of the supporting members 11 is formed with an arc surface for placing the motor of the air-conditioning compressor, and the top surface of the other supporting member 11 is downwardly concave with a plurality of grooves extending along the first horizontal direction, the grooves are used to accommodate the air-conditioning compressor body and limit the movement of the air-conditioning compressor along the second horizontal direction, and the top surface of the other supporting member 11 is upwardly convex with a plurality of bosses, the bosses are used to insert the air-conditioning compressor body and limit the movement of the air-conditioning compressor along the first horizontal direction, the translation structure 4 is used to drive the supporting structure 1 to move in the horizontal direction, and the lifting structure 5 is used to change the height of the supporting structure 1.

[0040] When installing the air-conditioning compressor, first place the air-conditioning compressor on the support structure 1, place the motor part on one of the supports 11 with an arc-shaped surface, and place the body on the other support 11. When placing the body, align the groove part on the body with the boss, and try to align the groove near the boss with the raised part on the body to complete the preliminary positioning of the air-conditioning compressor. Then, adjust the horizontal position of the air-conditioning compressor through the translation structure 4, and then adjust the height of the air-conditioning compressor through the lifting structure 5. With the mutual cooperation of the translation structure 4 and the lifting structure 5, the air-conditioning compressor is gradually moved to the preset installation position, and then the installation and fixing of the air-conditioning compressor are completed through the corresponding tools.

[0041] The function of the translation structure 4 is to drive the air-conditioning compressor to move in the horizontal direction. There are many structures that can achieve this function, for example, the ball screw nut substructure: the ball screw is used as the transmission element, the nut is connected to the support structure 1, the motor drives the ball screw to rotate, and the nut moves axially on the screw, thereby driving the support structure 1 to translate. It has the advantages of high transmission efficiency, high positioning accuracy, and large load-bearing capacity, and is suitable for occasions with high requirements for translation accuracy and load.

[0042] The function of the lifting structure 5 is to adjust the height of the air-conditioning compressor. There are many structures that can achieve this function. For example, the hydraulic lifting structure 5 is mainly composed of a hydraulic pump station, a hydraulic cylinder, a control valve, etc. The hydraulic pump station pressurizes the hydraulic oil and sends it to the hydraulic cylinder to push the piston up and down, thereby driving the support structure 1 to rise and fall. It has the advantages of large carrying capacity, fast lifting speed, and smooth operation, but it needs to be equipped with a hydraulic system, the cost is relatively high, and it is often used for the lifting of large equipment.

[0043] Therefore, in the technical solution provided by the present invention, the support structure 1 includes a support platform 12 and two support members 11, and two support members 11 are arranged at intervals on the top of the support platform 12 along the first horizontal direction, wherein the top surface of one of the support members 11 is formed with an arc surface for placing the motor of the air-conditioning compressor, and the top surface of the other support member 11 is downwardly concave with a plurality of grooves extending along the first horizontal direction, and the grooves are used to accommodate the air-conditioning compressor body and limit the movement of the air-conditioning compressor along the second horizontal direction, and the top surface of the other support member 11 is upwardly convex with a plurality of bosses, and the bosses are used to insert the air-conditioning compressor body and limit the movement of the air-conditioning compressor along the first horizontal direction, the translation structure 4 is used to drive the support structure 1 to move in the horizontal direction, and the lifting structure 5 is used to change the height of the support structure 1, and the two support members 11 on the support structure 1 can stably adjust the installation position in the same state during the adjustment of the installation position, and cooperate with the translation structure 4 and the lifting structure 5 to complete the adjustment of the position of the air-conditioning compressor.

[0044] Some air-conditioning compressor bodies have no recessed areas but only raised areas that are placed in the grooves. When the grooves have openings on two opposite sides in the same direction, the body may scratch the groove along the openings and then detach from the support member 11. Therefore, certain restrictions are required. Specifically, in an embodiment of the present invention, an anti-slip portion is provided on the cavity wall of the groove, and the anti-slip portion is in contact with the air-conditioning compressor body to limit the sliding of the air-conditioning compressor body, and the support member 11 can be detachably mounted on the support platform 12.

[0045] By providing an anti-slip portion on the inner wall of the groove, the raised portion of the body is difficult to slide after being placed in the groove, thereby reducing the possibility of the body detaching from the support 11. At the same time, the support 11 is set in a detachable and replaceable mode, which is convenient for the staff to replace the corresponding support 11 according to the different shapes of the air-conditioning compressor shell, and avoid the air-conditioning compressor being unable to be stably placed on the support 11 for adjustment of the installation position due to incompatibility.

[0046] Furthermore, the bottom of the support platform 12 is rotatably connected to an optical axis 2 , and the optical axis 2 is used to adjust the horizontal angle of the support structure 1 . A first support plate 3 is provided between the optical axis 2 and the translation structure 4 .

[0047] After the air-conditioning compressor is placed on the support structure 1, not only its horizontal position but also its horizontal angle needs to be adjusted so that it can adapt to the inclination angle of the installation position. Therefore, an optical axis 2 is provided to facilitate the rotation of the support platform 12 to adjust the horizontal angle of the air-conditioning compressor. At the same time, the optical axis 2 is connected to the translation structure 4 support through the first support plate 3 to avoid the translation structure 4 being composed of multiple tracks, and also makes the support structure 1 more stable in the horizontal direction.

[0048] When installing an air-conditioning compressor, not every site has convenient access to electricity. In order to ensure that the positioning device 100 can be applied to different lengths, it is designed to be a mode that does not require electricity. Specifically, in an embodiment of the present invention, the translation structure 4 includes a second guide rail 42, a second slider 41, a first guide rail 44 and a first slider 43. The second guide rail 42 extends along the second horizontal direction, and the second slider 41 is movably installed on the second guide rail 42 to drive the support structure 1 to move along the second horizontal direction. The first guide rail 44 is installed on the top of the second slider 41 and extends along the first horizontal direction. The first slider 43 is movably installed on the first guide rail 44 and is arranged at the bottom of the first support plate 3 to drive the support structure 1 to move along the first horizontal direction.

[0049] The guide rail and slider are a mature motion guide mechanism with high precision and stability. The second slider 41 moves on the second guide rail 42, and the first slider 43 moves on the first guide rail 44. The guide rail can provide precise guidance for the movement of the slider, reducing offset and shaking during movement. When adjusting the position of the support structure 1, this structure can ensure that the support structure 1 moves smoothly, avoiding the positioning accuracy of the air-conditioning compressor affected by shaking or offset. For example, when the air-conditioning compressor is placed on the support structure 1, the smooth movement of the support structure 1 can ensure that the fit between the air-conditioning compressor and the support 11 is more accurate, reducing installation errors, and the first guide rail 44 is installed on the top of the second slider 41. This layered design makes the movement in the first horizontal direction and the second horizontal direction independent of each other. When adjusting the position in one direction, it will not affect the positioning of the other direction, thereby improving the overall positioning accuracy. For example, when it is necessary to adjust the position of the support structure 1 in the first horizontal direction alone, it is only necessary to control the first slider 43 to move on the first guide rail 44, while the position in the second horizontal direction remains unchanged, which is convenient to operate and can be precisely controlled.

[0050] Furthermore, a second support plate is provided between the translation structure 4 and the lifting structure 5 .

[0051] In order to ensure the stability of the lifting structure 5 when adjusting the height, multiple lifting structures 5 will be designed and arranged symmetrically. Multiple lifting structures 5 concentrated on one guide rail are too crowded and inconvenient to operate. Therefore, a second support plate is set between the lifting structure 5 and the translation structure 4 to facilitate the adaptive installation of multiple lifting structures 5 while facilitating operation.

[0052] In an embodiment of the present invention, the lifting structure 5 includes a fixed rod 51, a movable rod 54 and a positioning nut 52. The fixed rod 51 is installed at the bottom of the second support plate. A movable hole is opened at the bottom of the fixed rod 51. The movable hole is extended along the axial direction of the fixed rod 51. The movable rod 54 is slidably set in the movable hole, and the outer peripheral side of the movable rod 54 is provided with a thread. The positioning nut 52 is threadedly connected to the movable rod 54 and abuts against the bottom end of the fixed rod 51 to limit the position of the fixed rod 51.

[0053] The height adjustment function of the lifting structure 5 works in conjunction with the translation structure 4 and the optical axis 2, so that the entire positioning device 100 can accurately position and install the air-conditioning compressor in three-dimensional space. For example, before placing the air-conditioning compressor on the support structure 1, the support structure 1 is first adjusted to a suitable height through the lifting structure 5, and then the translation structure 4 is used to adjust it horizontally, and finally the positioning of the air-conditioning compressor is completed by relying on the positioning components of the support structure 1.

[0054] The lifting mechanism 5 primarily consists of a fixed rod 51, a movable rod 54, and a positioning nut 52. Compared to complex lifting mechanisms such as hydraulic lifting systems, it has fewer components and a simpler structure. This makes manufacturing and installation relatively easy, reducing production costs and installation difficulty. For example, during the manufacturing process, the fixed rod 51 and movable rod 54 can be manufactured using simple machining processes, while the positioning nut 52 is a common standard component that is easy to purchase and install. Due to its simple structure, if a malfunction occurs during use, maintenance personnel can quickly locate the problem and perform repairs.

[0055] The outer peripheral side of the movable rod 54 is provided with a thread, and the positioning nut 52 is threadedly connected to the movable rod 54 and abuts against the bottom end of the fixed rod 51. After adjusting the height of the support structure 1, tighten the positioning nut 52. The threaded cooperation between the positioning nut 52 and the movable rod 54 will generate a certain friction force, thereby limiting the sliding of the movable rod 54 in the movable hole, playing a self-locking role. This enables the support structure 1 to maintain a stable height during operation and will not accidentally fall due to the weight of the air-conditioning compressor or other external forces, thereby improving the safety and stability of the positioning device 100.

[0056] Furthermore, the limiting nut 53 is threadedly connected to the movable rod 54, and the limiting nut 53 abuts against the bottom end of the positioning nut 52. During use, it is inevitable to move the entire positioning device 100. The movement of the entire positioning device 100 will cause all parts to vibrate. The positioning nut 52 is very likely to loosen after being vibrated, resulting in the problem of instability and height change of the lifting structure 5. Therefore, the positioning nut 52 needs to be restricted to a certain extent. The limiting nut 53 is threadedly connected to the movable rod 54 and is located at the bottom side of the positioning nut 52. When the positioning nut 52 is rotated to fit the bottom of the fixed rod 51, the limiting nut 53 is rotated so that the limit is rotated to the bottom of the positioning nut 52 again. Before the positioning nut 52 can move, the limiting nut 53 needs to move first, thereby restricting the movement of the positioning nut 52 and ensuring the stability of the lifting structure 5.

[0057] The horizontal position of the air-conditioning compressor can be adjusted within a small range through the translation structure 4. However, when the horizontal position needs to be adjusted within a large range, a larger guide rail structure is required, which easily makes the entire device too large and the manufacturing cost too high. Therefore, it is necessary to design a new structure to enable the positioning device 100 to move within a large range. Specifically, in an embodiment of the present invention, a universal wheel 6 is provided at the end of the movable rod 54 away from the second support plate. The universal wheel 6 allows the entire positioning device 100 to be moved to any position in the horizontal direction, so that the positioning device 100 can be moved as needed in a larger space, facilitating subsequent storage. At the same time, in conjunction with the translation structure 4, the horizontal position of the air-conditioning compressor is adjusted. The universal wheel 6 roughly moves the air-conditioning compressor to a suitable area. The horizontal position of the air-conditioning compressor is precisely adjusted through the translation structure 4, thereby improving installation efficiency while saving costs. In addition, the positioning device 100 does not need to be designed to be too large, facilitating subsequent storage and transportation.

[0058] Furthermore, the universal wheel 6 is provided with a locking assembly 7 that abuts against the ground to limit the movement of the universal wheel 6. After the universal wheel 6 has moved to a suitable area, it is necessary to restrain the universal wheel 6 so that the positioning device 100 does not continue to move significantly with the universal wheel 6. Therefore, the locking assembly 7 that abuts against the ground is provided to lock the universal wheel 6. After moving to the suitable position, the positioning device 100 cannot move, and the position of the air conditioner compressor can only be adjusted by the translation structure 4.

[0059] Specifically, in an embodiment of the present invention, the locking assembly 7 includes a fixing member 72 and a locking screw 71. The fixing member 72 is arranged at the bottom end of the movable rod 54, and a threaded hole is opened on the fixing member 72, and the threaded hole extends toward the second support plate. One end of the locking screw 71 passes through the fixing member 72 to support the ground, and the locking screw 71 is threadedly connected to the fixing member 72.

[0060] When locking the position of the universal wheel 6, turn the locking screw 71. During the rotation process, one end of the locking screw 71 gradually approaches the ground until it is in contact with the ground, thereby completing the work of abutting the ground. After the locking screw 71 on each universal wheel 6 is rotated until it abuts against the ground, the preliminary locking work is completed. If the locking is not stable enough at this time, continue to turn the locking screw 71 to lift the universal wheel 6 off the ground, so that the universal wheel 6 completely loses the ability to move, thereby preventing the positioning device 100 from moving.

[0061] The locking assembly 7 consists of a fixing part 72 and a locking screw 71. The structure is simple and easy to manufacture. The fixing part 72 is arranged at the bottom end of the movable rod 54 and cooperates with the locking screw 71 by opening a threaded hole. The installation process is relatively simple and does not require complicated tools and processes, thereby reducing production and maintenance costs. In addition, since the locking screw 71 is threadedly connected to the fixing part 72, the extension length thereof can be easily adjusted by rotating the locking screw 71 according to the ground conditions and actual needs to adapt to different ground flatness and height requirements, thereby ensuring the supporting effect and improving the versatility and adaptability of the locking assembly 7.
