[0002] Screw compressor is a rotary compressor, widely used in various fields that require gas compression. It compresses gas through the relative rotation of two rotors. However, the machining accuracy of the rotors is limited, and there will be a meshing gap between the rotors. The gap will increase the internal leakage of the compressor, reduce the energy efficiency of the compressor, and affect the service life of the product. In order to reduce the meshing gap between the rotors, a coating can be filled on the surface of the rotor, which can play a certain role in filling the meshing gap, reduce the leakage area to a certain extent, improve the volumetric efficiency of the compressor, and reduce the wear of the rotor and increase the service life of the product.

[0039] See also Figure 1 , Figure 2 and Figure 3The embodiment of the utility model provides a rotor identification device, which is installed on a rotating table 4 rotatably arranged on a rotor rotating device. The rotor identification device 1 includes: a weighing component 11, a diameter detection component 12 and a limit component 13; the weighing component 11 is installed on the rotating table 4; the diameter detection component 12 is installed on the weighing component 11; the limit component 13 is installed on the diameter detection component 12; wherein the limit component 13 is used to abut against the rotor 8 when the rotor 8 is placed on the rotor identification device 1, so that the pivot of the rotor 8 is positioned in the diameter detection component 12.

[0040] In this embodiment, both the weighing component 11 and the diameter detection component 12 are built with wireless transmission modules, and the weight of the rotor 8 weighed by the weighing component 11 and the pivot diameter of the rotor 8 detected by the diameter detection component 12 can be sent to the rotor rotating device through the corresponding wireless transmission module. Specifically, the weighing component 11 can adopt a spoke-type weighing sensor, the bottom of the weighing component 11 is fixedly mounted on the rotating table 4, the top of the weighing component 11 is the weighing platform, the bottom of the diameter detection component 12 is mounted on the weighing platform at the top of the weighing component 11, and the bottom of the limit component 13 is mounted on the top of the diameter detection component 12, that is, when the rotor 8 is not placed, the weighing component 11 already carries the diameter detection component 12 and the limit component 13, that is, when the rotor 8 is placed, the weight increase on the weighing component 11 is the weight of the rotor 8. Specifically, after the rotor 8 is placed on the rotor identification device 1 , it is held and fixed by the limiting assembly 13 , so that the rotor 8 can be in a vertical state and the pivot of the rotor 8 is positioned in the diameter detection assembly 12 , and the pivot diameter of the rotor 8 can be detected by the diameter detection assembly 12 .

[0041] Based on this, before spraying the rotor 8, the rotor 8 is first supported by the limit assembly 13 to ensure the stability of the rotor 8; the weight and diameter of the rotor 8 are respectively obtained by the weighing assembly 11 and the diameter detection assembly 12 to obtain the specifications of the rotor 8; and the rotor 8 is driven by the rotor rotating device to execute a rotation mode corresponding to the specifications, thereby realizing automatic adaptive spraying of rotors 8 of different specifications to improve the spraying effect of rotors 8 of different specifications.

[0042] It should be noted that the pivot diameters of some rotors 8 of different specifications are the same, or the weights are very close. Therefore, it is not accurate enough to determine the specifications of the rotor 8 by only obtaining the pivot diameter or weight of the rotor 8. The present embodiment ensures the accuracy of specification identification by obtaining the pivot diameter and weight of the rotor 8 for coordinated determination.

[0043] See also Figure 4 and Figure 5 , the diameter detection component 12 of the present application is described in detail below.

[0044] In one embodiment, the diameter detection assembly 12 includes a limiting tray, a limiting slot 121 is provided on the limiting tray, the pivot of the rotor 8 is positioned in the limiting slot 121 , and a sensor 122 for detecting the pivot diameter of the rotor 8 is provided in the limiting slot 121 .

[0045] In this embodiment, the shape of the limiting tray can be a disc, and the limiting tray can be fixedly installed on the weighing platform on the top of the weighing assembly 11 by screws. A limiting groove 121 can be opened at the center position of the top of the limiting tray. The shape and size of the limiting groove 121 can be adapted to the pivots of rotors 8 of various specifications. A sensor 122 is arranged on the inner side of the limiting groove 121. When the rotor 8 is placed on the rotor identification device 1, the pivot of the rotor 8 is first positioned in the limiting groove 121, and then the limiting assembly 13 is used to support the rotor 8 to keep the rotor 8 stable. At this time, the sensor 122 on the inner side of the limiting groove 121 senses and detects the pivot of the rotor 8, so that the pivot diameter of the rotor 8 can be obtained.

[0046] In one embodiment, the limiting groove 121 in the limiting tray may include a plurality of sinks with different diameters, the diameters of the plurality of sinks decrease successively along the depth direction of the limiting groove 121, and a sensor 122 is installed on the inner wall of each sink.

[0047] In the present embodiment, based on the pivot diameters of rotors 8 of various specifications, a plurality of sinkers with different diameters are provided accordingly, one sinker corresponds to the pivot of a rotor 8 of one specification, and the diameters of the plurality of sinkers decrease successively along the depth direction of the limiting groove 121; based on this, when the pivot of a rotor 8 of one specification is positioned at the corresponding sinker, the sensor 122 on the inside of the sinker can sense the pivot of the rotor 8, thereby confirming the pivot diameter of the rotor 8.

[0048] It should be noted that it is necessary to set the priorities of multiple sensors 122. The priorities of multiple sensors 122 increase as the diameter of the sinker decreases, that is, the sensor 122 in the sinker with a smaller diameter has a higher priority. When the pivot of the rotor 8 is sensed by at least two sensors 122, the sensing signal of the sensor 122 with the highest priority needs to be selected as the sensing result of this time. For ease of understanding, three specifications of rotor 8 are taken as examples. The pivot diameters of the three specifications of rotor 8 are D1, D2 and D3, which decrease in sequence. Correspondingly, the limiting groove 121 includes a first sinker, a second sinker and a third sinker. The diameters of the first sinker, the second sinker and the third sinker are d1, d2 and d3, which decrease in sequence along the depth direction of the limiting groove 121. The pivot diameter D1 can only be positioned in the first sinker d1 (i.e., D1>d2), the pivot diameter D2 can be positioned in the second sinker d2 (i.e., D2>d3), and the pivot diameter D3 can be positioned in the third sinker d3. When the pivot diameter D2 is positioned in the second sinker d2, the sensors 122 on the inside of the first sinker and the second sinker will both sense the pivot of the rotor 8. According to the priority setting, the priority of the sensor 122 on the inside of the second sinker is greater than that of the sensor 122 on the inside of the first sinker. Therefore, the sensing information of the sensor 122 on the inside of the second sinker is used as the sensing result of this time.

[0049] It should also be noted that the diameter of each sinker can be slightly larger than the pivot diameter of the corresponding specification rotor 8, that is, d1>D1, d2>D2, d3>D3, and a chamfer can be set on each sinker so that the pivot of the rotor 8 can be better positioned in the corresponding sinker.

[0050] See also Figure 6 , the limiting component 13 of the present application is introduced in detail below.

[0051] In one embodiment, the limiting assembly 13 includes a limiting chuck 131 and a plurality of blocks 132; the limiting chuck 131 is provided with a central through hole for the pivot of the rotor 8 to pass through; the plurality of blocks 132 are slidably mounted on the top of the limiting chuck 131 and are evenly distributed on the periphery of the central through hole, and the sliding direction of the blocks 132 is toward the axis of the central through hole.

[0052] In this embodiment, the limiting chuck 131 can be a circular column with an axially opened central through hole. The limiting chuck 131 can be fixedly installed on the top of the limiting tray by means of screws. The central through hole of the limiting chuck 131 corresponds to the limiting groove 121 of the limiting tray in the axial direction. The pivot of the rotor 8 passes through the central through hole of the limiting chuck 131 and is positioned in the limiting groove 121 of the limiting tray. In order to ensure that the pivot of the rotor 8 can be stably positioned in the limiting groove 121, a plurality of blocks 132 arranged on the top of the limiting chuck 131 are respectively supported on the outer periphery of the pivot of the rotor 8 from multiple directions, thereby ensuring the stability of the rotor 8.

[0053] Preferably, the number of the blocks 132 can be set to at least three and distributed along the circumferential direction on the outer circumference of the middle through hole. When multiple blocks 132 slide close to the middle through hole, they abut against the pivot of the rotor 8, and when multiple blocks 132 slide away from the middle through hole, they release the pivot of the rotor 8.

[0054] In this embodiment, in order to avoid damage to the workpiece when the block 132 is rigidly pressed against the pivot of the rotor 8, a protective sleeve 133 can be mounted on each block 132. The protective sleeve 133 preferably adopts a high-strength rubber sleeve, and the hardness of the high-strength rubber sleeve is 50A to 70A on the Shore A hardness. The protective sleeve 133 can also be made of polyurethane, silicone rubber, natural rubber, chloroprene rubber, fluororubber, nitrile rubber and other materials. More specifically, the inner side of the protective sleeve 133 has a small interference fit with the side surfaces of the block 132, and the interference amount is 0.1 to 0.2 mm, which can prevent the protective sleeve 133 from loosening.

[0055] See also Figure 2 , Figure 3 and Figure 7 The embodiment of the utility model also provides a rotor rotation device, including the rotor identification device 1 as above, the rotor rotation device includes: a device body 2, a rotating drive member 3 and a rotating table 4; the rotating drive member 3 is arranged inside the device body 2; the rotating table 4 includes a connecting shaft 41 and a mounting table 42, the bottom end of the connecting shaft 41 penetrates into the device body 2 and is connected to the rotating drive member 3, the mounting table 42 is installed on the top of the connecting shaft 41 and is located at the top of the device body 2, and the rotor identification device 1 is installed on the mounting table 42.

[0056] In this embodiment, the device body 2 serves as the control center of the entire device and can control the rotary drive member 3 to drive the rotating table 4 to rotate at different speeds, so as to drive the rotor 8 on the rotor identification device 1 to rotate at different speeds.

[0057] In this embodiment, the rotating driving member 3 is a variable frequency motor, which is fixedly installed inside the equipment body 2 through a mounting frame. An opening is provided on the top of the equipment body 2, and a bearing member 21 is installed at the opening. The connecting shaft 41 is rotatably installed in the bearing member 21. The bottom end of the connecting shaft 41 passes through the opening and enters the interior of the equipment body 2 and is connected to the output end shaft of the variable frequency motor. The top end of the connecting shaft 41 protrudes out of the top of the equipment body 2. The rotating table 4 is a disc-shaped structure, and the bottom center position of the rotating table 4 is connected to the top end of the connecting shaft 41. The rotating table 4 and the connecting shaft 41 can be arranged as one piece or separately. In this way, the rotating table 4 can be driven to rotate on the top of the equipment body 2 by the variable frequency motor, and the rotor 8 on the identification device can be rotated.

[0058] See also Figure 2In one embodiment, the rotor rotating device also includes a waste liquid collection component, which includes a waste liquid tray 5 and a guide pipe 6; the waste liquid tray 5 is arranged on the top of the device body 2, and a bypass opening for avoiding the rotating table 4 is opened on the waste liquid tray 5; one end of the guide pipe 6 is connected to the waste liquid tray 5, and the other end of the guide pipe 6 is connected to the waste liquid storage device arranged externally.

[0059] In this embodiment, the waste liquid tray 5 has a certain depth and can collect a certain volume of waste. The overall shape of the waste liquid tray 5 can be adapted to the shape of the top surface of the equipment body 2. An escape port for avoiding the rotating table 4 is opened on the waste liquid tray 5. A plurality of supporting parts supported on the top surface of the equipment body 2 are arranged at the bottom of the waste liquid tray 5. The waste liquid tray 5 is installed on the top surface of the equipment body 2 in a detachable manner; during the spraying operation of the rotor 8, after the waste tray collects the paint waste during the spraying process, the waste can enter the guide pipe 6 from the waste hole opened on the corner of the waste tray, and the waste is recovered to the waste liquid storage device arranged outside through the guide pipe 6. The waste liquid tray 5 can be removed after the spraying work of the rotor 8 is completed.

[0060] Specifically, a rubber plug can be set in the waste hole.

[0061] In one embodiment, a flange 51 is provided at the edge of the avoidance opening of the waste liquid tray 5 ; and a guide portion 52 for guiding the waste liquid is provided on the top surface of the waste liquid tray 5 .

[0062] In this embodiment, after the paint waste falls into the waste tray during the spraying process, in order to prevent the waste from entering the opening at the top of the equipment body 2 from the avoidance port of the waste liquid tray 5, a flange 51 is provided at the edge of the avoidance port of the waste liquid tray 5. The flange 51 can provide the first line of protection for the waste paint mist and dust, and prevent the waste from entering the interior from the opening at the top of the equipment body 2. In addition, in order to prevent the waste liquid from staying near the avoidance port, a guide portion 52 for guiding the waste liquid to the surroundings is provided on the top surface of the waste liquid tray 5. The guide portion 52 can be an inclined surface that gradually decreases in the radial outward direction of the avoidance port, so as to facilitate guiding the waste liquid to the surroundings.

[0063] In one embodiment, the diameter of the avoidance opening of the waste liquid tray 5 can be set smaller than the diameter of the mounting platform 42, that is, the flange 51 on the avoidance opening is located at the bottom of the mounting platform 42, so that the first line of protection can achieve a better waste liquid barrier effect.
