[0001] This utility model relates to the field of spraying equipment technology, specifically a positioning device for spraying air conditioner housings. Background Technology

[0002] Air conditioner casing coating is a key process in air conditioner manufacturing that combines protection and decoration. By forming a uniform coating on the surface of a metal or plastic substrate, it significantly improves the product's durability and aesthetics.

[0003] Chinese Patent Publication No. CN221108643U discloses an air conditioner casing spraying device, including a processing machine, a turntable, and an auxiliary device. The turntable is rotatably connected to the surface of the processing machine. The auxiliary device is disposed on the surface of the processing machine and includes a guide plate, which is fixedly connected to the surface of the processing machine and located below the turntable. A groove is formed on the surface of the guide plate, which is located below the turntable. A slider is slidably connected to the surface of the groove, and the slider contacts the surface of the guide plate. The slider is located below the turntable. This utility model, by setting up an auxiliary device, effectively assists the worker in unloading materials. When the air conditioner casing spraying device is in use, the device is used to adjust the support plate, avoiding the time-consuming situation of unloading materials due to cumbersome steps, thus improving the practicality and auxiliary function of the air conditioner casing spraying device and improving the convenience of unloading materials for the worker.

[0004] In the aforementioned prior art, the air conditioner casing can be placed on the support of a turntable for spraying. As can be seen from the prior art, the rotation of the turntable needs to be controlled during spraying to switch the air conditioner casing. However, when installing the air conditioner casing, it is placed directly on the support, lacking effective fixing and positioning measures. If the placement position of the air conditioner casing is offset, it is easy for the air conditioner casing to fall off when the turntable rotates, affecting the spraying work. Therefore, a positioning device for air conditioner casing spraying is needed to meet people's needs. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning device for air conditioner casing spraying, so as to solve the problem mentioned in the background art that the air conditioner casing is prone to fall off when the turntable rotates due to the lack of effective fixing measures on the spraying machine turntable support.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for spraying air conditioner housings, comprising a spraying machine and an air conditioner housing, wherein a rotating seat is provided on the spraying machine; an mounting seat is installed on the rotating seat, and a bidirectional lead screw is rotatably installed inside the mounting seat, and two sliding frames are threaded on the bidirectional lead screw, both sliding frames being slidably mounted on the mounting seat, and both sliding frames being connected to a pressing structure and a clamping structure, wherein a linkage structure connects the pressing structure and the clamping structure.

[0007] Preferably, the extrusion structure includes a fixed guide rod, which is installed on one side of the sliding frame. A pulley frame is slidably sleeved on the fixed guide rod, and an extrusion pulley is rotatably installed inside the pulley frame. The extrusion pulley contacts the inner wall of the air conditioner housing. A spring is slidably sleeved on the fixed guide rod, and the two ends of the spring are respectively arranged between the pulley frame and the sliding frame.

[0008] Preferably, a stop bar is installed at one end of the fixed guide rod, and a sliding hole is opened inside the pulley frame, in which the fixed guide rod is slidably installed.

[0009] Preferably, the clamping structure includes two linkage slide rods, both of which are slidably mounted on the sliding frame, and a clamping plate is installed at one end of each linkage slide rod.

[0010] Preferably, a rubber pad is installed on one side of the clamping plate, and the rubber pad is in contact with the surface of the air conditioner housing.

[0011] Preferably, the linkage structure includes a fixed rod, which is installed on one side of the pulley frame. Two connecting rods are rotatably mounted on one end of the fixed rod, and the other ends of the two connecting rods are rotatably mounted on one side of two linkage slide rods, respectively.

[0012] Preferably, the inner walls on both sides of the linkage slide rod are provided with guide grooves, and guide bars are slidably installed in both guide grooves. The two guide bars are respectively installed on both sides of the sliding frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In use, the air conditioner housing can be placed on the linkage slide rods on both sides. By rotating the bidirectional screw, the two sliding frames can be moved simultaneously, thereby causing the two pressing pulleys to press against the inner walls of both sides of the air conditioner housing. If the bidirectional screw is continuously rotated, the sliding frames can be continuously moved and the springs can be compressed. The spring force will act on the pressing pulleys, making the pressing pulleys fit more tightly against the inner walls of the air conditioner housing. Through the pressing setting of the two pressing pulleys, the position of the air conditioner housing can be fixed, preventing the housing from shifting or falling off when the rotating seat rotates to change the position of the air conditioner housing.

[0015] (2) During the continuous movement, the linkage slide rods on both sides will be pulled by the two connecting rods, which will drive the two clamps to move towards the air conditioner housing at the same time. Finally, the rubber pads on both sides will be clamped on the air conditioner housing to correct and position the air conditioner housing, ensuring that the air conditioner housing is located in the middle position above the mounting base, and further improving the installation stability of the air conditioner housing.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a positioning device for spraying air conditioner housings, including a spraying machine 100 and an air conditioner housing 101. A rotating seat 102 is provided on the spraying machine 100; a mounting base 200 is installed on the rotating seat 102, and a bidirectional lead screw 208 is rotatably mounted inside the mounting base 200. Two sliding frames 201 are threaded onto the bidirectional lead screw 208. The two ends of the bidirectional lead screw 208 are provided with threads facing opposite directions, and the threads are adapted to the sliding frames 201, so that the rotating bidirectional lead screw 208 can... The two sliding frames 201 move simultaneously toward each other or toward each other. Both sliding frames 201 are slidably mounted on the mounting base 200. Both sliding frames 201 are connected to a pressing structure and a clamping structure. The pressing structure is used to press against the inner wall of the air conditioner housing 101 to improve the stability of the air conditioner housing 101. The pressing structure and the clamping structure are connected by a linkage structure. The linkage structure can be used to drive the clamping structure to clamp the two sides of the air conditioner housing 101 when the pressing structure is running, so as to correct the position of the air conditioner housing 101.

[0023] Furthermore, the extrusion structure includes a fixed guide rod 202, which is installed on one side of the sliding frame 201. A pulley frame 203 is slidably sleeved on the fixed guide rod 202. An extrusion pulley 204 is rotatably installed inside the pulley frame 203. The extrusion pulley 204 contacts the inner wall of the air conditioner housing 101. The moving sliding frame 201 can drive the corresponding fixed guide rod 202 to move, thereby causing the extrusion pulley 204 on the pulley frame 203 to press against the air conditioner housing 101. On the inner wall, the air conditioner housing 101 is initially fixed and positioned. A spring 205 is slidably sleeved on the fixing guide rod 202. The two ends of the spring 205 are respectively arranged between the pulley frame 203 and the sliding frame 201. If the bidirectional lead screw 208 is continuously rotated, the sliding frame 201 can be continuously moved and the spring 205 can be compressed. The elastic force of the spring 205 will act on the pulley frame 203 and the compression pulley 204, making the compression pulley 204 fit more tightly with the inner wall of the air conditioner housing 101.

[0024] Furthermore, a stop bar 206 is installed at one end of the fixed guide rod 202. The stop bar 206 is used to protect the pulley frame 203 and prevent the pulley frame 203 from detaching from the fixed guide rod 202. A sliding hole 207 is provided inside the pulley frame 203. The fixed guide rod 202 is slidably installed in the sliding hole 207. When the fixed guide rod 202 moves, it can slide in the sliding hole 207.

[0025] Example 2: As Figure 2-4To correct and position the air conditioner housing 101 and prevent it from shifting, a clamping structure and a linkage structure are arranged. The clamping structure includes two linkage slide rods 300, both of which are slidably mounted on the sliding frame 201. A clamping plate 301 is mounted on one end of each of the two linkage slide rods 300, and a rubber pad 302 is mounted on one side of each clamping plate 301, contacting the surface of the air conditioner housing 101. The linkage structure includes a fixing rod 400, which is mounted on one side of the pulley bracket 203. Two connecting rods 401 are rotatably mounted on one end of the fixing rod 400, and the other ends of the two connecting rods 401 are rotatably mounted on... Installed on one side of the two linkage slide rods 300, the two linkage slide rods 300 will be pulled by the two connecting rods 401 when they move, and move simultaneously and move closer to each other. This causes the linkage slide rods 300 on both sides to drive the rubber pads 302 on the two clamping plates 301 to clamp the two sides of the air conditioner housing 101 at the same time. The inner walls of both sides of the linkage slide rods 300 are provided with guide grooves 402. Guide strips 403 are slidably installed in the two guide grooves 402. The two guide strips 403 are respectively installed on both sides of the sliding frame 201. When the linkage slide rods 300 move, they can slide on the guide strips 403 through the guide grooves 402, thereby preventing the position of the linkage slide rods 300 from shifting. The other features are the same as in embodiment 1.

[0026] The working principle is as follows: During use, both ends of the air conditioner housing 101 are placed on the linkage slide rods 300 on both sides. Then, rotating the bidirectional screw 208 drives the two sliding frames 201 to move simultaneously towards or away from each other. The moving sliding frames 201 drive the corresponding fixed guide rods 202 to move, causing the two fixed guide rods 202 to drive the pressing pulleys 204 on the two pulley frames 203 to simultaneously press against the inner wall of the air conditioner housing 101, initially fixing and positioning the air conditioner housing 101. Continuing to rotate the bidirectional screw 208 will cause the sliding frames 201 to move continuously and... The compression spring 205 simultaneously drives the fixed guide rod 202 to slide within the sliding hole 207. The elastic force of the spring 205 acts on the pulley frame 203 and the compression pulley 204, making the compression pulley 204 fit more tightly against the inner wall of the air conditioner housing 101. The continuously moving sliding frame 201 drives the two linkage slide rods 300 to move. When the two linkage slide rods 300 move, they are pulled by the two connecting rods 401 and move simultaneously and approach each other. This causes the linkage slide rods 300 on both sides to simultaneously clamp the rubber pads 302 on the two clamping plates 301 onto both sides of the air conditioner housing 101, forming a... Figure 1 and Figure 2In this state, while clamping, the position of the air conditioner housing 101 can be corrected and positioned to ensure that the air conditioner housing 101 is located in the middle position above the mounting base 200. The air conditioner housing 101 will drive the friction compression pulley 204 to rotate. The setting of the compression pulley 204 makes the air conditioner housing 101 move more smoothly during correction.
