Description

Technical Field

[0001] This utility model relates to the field of compressor testing technology, and more specifically, to a compressor pump body axial clearance testing device and a production line including the testing device. Background Technology

[0002] In reciprocating refrigeration compressors, such as Figure 1 As shown, a compressor typically consists of components such as a crankshaft, connecting rod, piston pin, piston, and cylinder block (or crankcase). In the compressor manufacturing process, rotor heat fitting is often used to assemble the crankshaft and rotor. However, due to limitations of the accompanying tooling, the axial clearance of the compressor body cannot be automatically detected after assembly.

[0003] Currently, the common method for detecting the axial clearance of compressor pump bodies involves workers directly inserting a fixed-thickness squeegee into the gap between the counterweight on the crankshaft and the outer wall of the pump body, estimating the axial clearance by the ease of insertion. This method is extremely inaccurate, frequently leading to misjudgments during inspection, making it difficult to guarantee the quality of the compressor.

[0004] Therefore, there is an urgent need for a detection device that can automatically detect the axial clearance of the compressor pump body. Utility Model Content

[0006] To achieve the purpose of this utility model, the technical solution adopted is as follows: a compressor pump body axial clearance detection device, including a frame and a traveling tooling plate for installing the compressor. The frame is equipped with a vertical frame and a first lifting mechanism for lifting the traveling tooling plate. A limiting block seat plate is installed at the upper end of the vertical frame, which can approach or move away from the traveling tooling plate. A positioning sleeve that can abut against the crankshaft on the compressor pump body and a pressing structure that presses the compressor pump body are installed on the limiting block seat plate. The positioning sleeve can move up and down on the limiting block seat. A displacement sensor for detecting the vertical displacement of the positioning sleeve is also installed on the vertical frame. A second lifting mechanism for lifting the crankshaft on the compressor pump body is jointly installed on the traveling tooling plate and / or the vertical frame.

[0010] Furthermore, there are two pushing structures, each including a telescopic element and a push rod that fixes the output end of the telescopic element, and the two push rods correspond to the two ends of the pin respectively.

[0011] Furthermore, the diameter of the top sleeve matches the counterweight on the crankshaft, and the top sleeve also has a notch to avoid the connecting rod on the compressor.

[0012] Furthermore, support plates are installed on opposite sides of the support frame, and two pushing structures are respectively installed on the two support plates.

[0013] Furthermore, an installation plate is also installed on the top of the support frame, a guide sleeve is installed on the installation plate, and a guide post that can move up and down is installed inside the guide sleeve.

[0014] Furthermore, a guide shaft is vertically inserted through the limiting block seat plate, the guide shaft slides with the limiting block seat plate, and a fixing block is installed at the upper end of the guide shaft, and a positioning sleeve is installed at the lower end of the guide shaft; a compression spring is also sleeved on the guide shaft, and the two ends of the compression spring abut against the positioning sleeve and the limiting block seat plate respectively.

[0015] Furthermore, the clamping structure includes two pressure plate limiting blocks installed on the limiting block seat plate and arranged symmetrically. A detachable positioning pressure plate is installed on the pressure plate limiting blocks, and the positioning pressure plate is also provided with a clamping stud for clamping the compressor pump body.

[0016] Furthermore, the first lifting mechanism includes a lifting platform that can move up and down on the frame and a lifting element that drives the lifting platform to move up and down, and the top of the lifting platform also has a positioning pin for positioning the tooling plate.

[0017] Furthermore, the frame is also equipped with a liftable limiting structure, which is located in front of the lifting mechanism.

[0018] Furthermore, the limiting structure includes a second lifting element mounted on the frame, and the output end of the second lifting element is also equipped with a roller.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0040] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] like Figure 3 As shown, the present invention provides a compressor pump body axial clearance detection device, including a frame 1 and a traveling fixture plate 17. The frame 1 is a frame structure, and four foot cups and four foot supports are installed at the lower end of the frame 1. The four foot cups and four foot supports are respectively installed on the four legs of the frame 1, and the foot supports are located on the outside of the foot cups. The traveling fixture plate 17 is used to fix the compressor pump body to be tested, and after the compressor pump body is installed on the traveling fixture plate 17, it can move forward along the conveyor track 2, so that the compressor pump body can be processed in an assembly line.

[0042] The frame 1 is also equipped with a first lifting mechanism 15, which can lift vertically. The accompanying tooling plate 17 is located above the first lifting mechanism 15. When the compressor pump body on the accompanying tooling plate 17 needs to be tested for axial clearance, the first lifting mechanism 15 lifts upward, lifting the accompanying tooling plate 17 off the conveying track 2, so that the accompanying tooling plate 17 is separated from the conveying track 2, thereby positioning the accompanying tooling and thus positioning the compressor pump body to be tested. After the axial clearance test of the compressor pump body on the accompanying tooling plate 17 is completed, the first lifting mechanism 15 retracts downward. At the same time as the first lifting mechanism 15 retracts downward, the accompanying tooling plate 17 is placed on the conveying track 2, so that the conveying track 2 can transport the accompanying tooling plate 17 to the next processing station.

[0043] A stand 3 is also installed on the frame 1. The stand 3 extends vertically upward on the frame 1, and a limit block seat plate 9 is installed on the upper end of the stand 3. The limit block seat plate 9 is located above the accompanying tooling plate 17. The limit block seat plate 9 can be close to or away from the accompanying tooling plate 17 on the stand 3. That is, when the compressor pump body to be tested is fixed on the accompanying tooling plate 17, the limit block seat plate 9 can be close to or away from the compressor pump body to be tested. A positioning sleeve 13 is installed on the limiting block seat plate 9. The positioning sleeve 13 is adapted to the crankshaft of the compressor pump body. When the limiting block seat plate 9 moves downward, the positioning sleeve 13 can abut against the crankshaft on the compressor pump body. In order to ensure that the positioning sleeve 13 can abut against the crankshaft while the crankshaft on the compressor pump body is subjected to an upward thrust, the positioning sleeve 13 should also be able to move up and down on the limiting block seat plate 9 during installation. However, the up and down movement of the positioning sleeve 13 is not achieved by a drive structure, but by the push of the crankshaft on the compressor pump body. Based on this, the distance that the positioning sleeve 13 moves upward is the axial clearance of the compressor pump body. In order to detect the axial clearance of the compressor pump body, a displacement sensor 8 is also installed on the support frame 3 to detect the up and down displacement of the positioning sleeve 13. The displacement sensor 8 is a direct use of the existing displacement sensor 8.

[0044] To prevent the crankshaft of the compressor pump body from causing other structures of the compressor pump body to move upward synchronously when subjected to upward thrust, a clamping structure 14 is also installed on the limit block seat plate 9. When the limit block seat plate 9 moves downward, it can drive the clamping structure 14 to move downward synchronously, so that the clamping structure 14, together with the first lifting mechanism 15, clamps and fixes the compressor pump body on the accompanying tooling plate 17, thus preventing the compressor pump body from moving up and down during the axial clearance detection process.

[0045] After the compressor pump body is fixed on the accompanying tooling plate 17, a second lifting mechanism 16 is installed on both the accompanying tooling plate 17 and the upright frame 3 to facilitate the lifting of the crankshaft on the compressor pump body. When the compressor pump body to be tested is installed on the accompanying tooling plate 17 and is pressed and fixed in conjunction with the first lifting mechanism 15 and the clamping structure 14, the crankshaft of the compressor pump body is lifted by the second lifting mechanism 16. After the crankshaft of the compressor pump body is subjected to the lifting force of the second lifting mechanism 16, the crankshaft of the compressor pump body will generate an upward displacement. While the crankshaft of the compressor pump body moves upward, it pushes the positioning sleeve 13 to move upward on the limit block seat plate 9. The displacement of the positioning sleeve 13 is measured by the displacement sensor 8, thereby obtaining the axial clearance of the compressor pump body and realizing the detection of the axial clearance of the compressor pump body.

[0046] In this utility model, without considering equipment costs and subsequent processing of the compressor pump body, the entire structure of the second lifting mechanism 16 can also be directly set on the accompanying tooling plate 17. Of course, this design will make the structure on the accompanying tooling plate 17 more complex and increase the processing cost of the accompanying tooling plate 17. Since the axial clearance of the compressor pump body will undergo other processing after the inspection is completed, setting the entire structure of the second lifting mechanism 16 on the accompanying tooling plate 17 may also affect the subsequent processing of the compressor pump body.

[0047] In this invention, to ensure the compressor pump body can be stably mounted on the accompanying tooling plate 17, the accompanying tooling plate 17 also includes support pins 1701 and a saddle frame 1702. The number and position of the support pins 1701 correspond to the number and position of the silencing cavities on the compressor pump body, so that when the compressor pump body needs to be mounted on the accompanying tooling plate 17, the top of the support pins 1701 is inserted into the silencing cavities on the compressor pump body, thus supporting the compressor pump body. The position and height of the saddle frame 1702 correspond to the position and height of the cylinder seat on the compressor pump body, so that when the compressor pump body needs to be mounted on the accompanying tooling plate 17, the saddle frame 1702 can support the cylinder seat on the compressor pump body. Through the combined action of the support pins 1701 and the saddle frame 1702, the compressor pump body can be stably mounted on the accompanying tooling plate 17.

[0048] In this utility model, such as Figure 5 , Figure 6 Figure 7As shown, the second lifting mechanism 16 includes a support base 1601 mounted on the accompanying tooling plate 17. A lifting pin 1602 that can move up and down is mounted on the support base 1601. During the up and down movement of the support base 1601, there is always a certain gap between the lower end of the lifting pin 1602 and the upper surface of the accompanying tooling plate 17. The upper end of the lifting pin 1602 also has a top sleeve 1603. The top sleeve 1603 corresponds to the crankshaft of the compressor pump body. The end of the top sleeve 1603 connected to the lifting pin 1602 is closed to facilitate the connection between the top sleeve 1603 and the lifting pin 1602, while the end of the top sleeve 1603 corresponding to the upper crankshaft of the compressor pump body is open.

[0049] Since the crankshaft of the compressor pump body is also equipped with counterweights, connecting rods, and other structures, in order to better push the crankshaft on the compressor pump body, the top sleeve 1603 is designed such that its center can be offset from the center of the crankshaft on the compressor pump body. A notch 1604 is opened at the open end of the top sleeve 1603 to avoid the connecting rod, so that the bottom of the notch 1604 is adapted to the end face of the crankshaft of the compressor pump body. The end face of the open end of the top sleeve 1603 corresponds to the counterweight. When the crankshaft on the compressor pump body needs to be lifted, the top sleeve 1603 can lift both the counterweight and the end face of the crankshaft at the same time, ensuring that the thrust on the crankshaft is more stable.

[0050] Of course, in this utility model, the inner diameter of the top sleeve 1603 can also be adapted to the crankshaft diameter of the compressor pump body, and a notch 1604 for avoiding the connecting rod can be opened at the open end of the top sleeve 1603. When it is necessary to lift the crankshaft on the compressor pump body, the top sleeve 1603 is fitted on the crankshaft of the compressor pump body, and the inner end face of the closed end of the top sleeve 1603 is in contact with the lower end face of the crankshaft on the compressor pump body, so that the lifting pin 1602 can lift the crankshaft on the compressor pump body during the process of driving the top sleeve 1603 to move up and down.

[0051] To ensure the up-and-down movement of the lifting pin 1602, a pin 1605 is also installed on the accompanying tooling plate 17. The pin 1605 can be inserted into or removed from the gap between the lifting pin 1602 and the accompanying tooling plate 17. The minimum thickness of the insertion end of the pin 1605 should be less than the gap between the lifting pin 1602 and the accompanying tooling plate 17 when the lifting pin 1602 is not raised, and the maximum thickness of the insertion end of the pin 1605 should be greater than the maximum axial clearance of the crankshaft on the compressor pump body. To facilitate the push of the lifting pin 1602 by the pin 1605, the lower end face of the lifting pin 1602 is an inclined surface that mates with the pin 1605. At the same time, to prevent the pin 1605 from rotating during the up-and-down movement of the lifting pin 1602, the width of the insertion end of the pin 1605 can be smaller than the diameter of the lower end of the lifting pin 1602. In this case, a U-shaped groove can be formed on the lower end face of the lifting pin 1602 to match the width clearance of the insertion end of the pin 1605, and the inclined surface that mates with the pin 1605 is set at the bottom of the U-shaped groove.

[0052] To ensure that the pin 1605 remains aligned with the same straight line during insertion or withdrawal of the lifting pin 1602 and the accompanying tooling plate 17, a guide groove can be formed on the pin 1605. The length of the guide groove is aligned with the direction of movement of the pin 1605, and the length of the guide groove is not less than the length formed by the movement of the pin 1605. Simultaneously, a guide pin 1609 is installed on the accompanying tooling plate 17, which can be inserted into the guide groove. The diameter of the guide pin 1609 is clearance-fitted with the width of the guide groove. Through the combined action of the guide pin 1609 and the guide groove, the pin 1605 can only move in one direction, preventing lateral displacement during movement.

[0053] To ensure the lifting and lowering movement of the lifting pin 1602, the support base 1601 in this utility model can be a cap structure. However, the support base 1601 needs to have an opening for the insertion and withdrawal of the pin 1605. That is, the side of the support base 1601 has two openings arranged opposite to each other. The two openings and the pin 1605 are on the same straight line as the diameter of the support base 1601. In order to ensure the insertion or withdrawal of the pin 1605, a pushing structure for pushing the pin 1605 is also installed on the stand 3.

[0054] In this utility model, such as Figure 3As shown, there are two pushing structures. During installation, first, a support plate 1608 is installed on two of the columns, and another support plate 1608 is installed on the other two columns, ensuring that the two support plates 1608 correspond to the two ends of the pin 1605. At the same time, a telescopic element 1606 is installed on each of the two support plates 1608, ensuring that the output end of the telescopic element 1606 is on the same straight line as the pin 1605. A push rod 1607 for pushing the pin 1605 is installed on the output end of each of the two telescopic elements 1606. The width of the push rod 1607 near the pin 1605 can gradually decrease, but when setting the push rod 1607, it is necessary to ensure that the size of the push rod 1607 is not larger than the opening size on the support base 1601, so that the push rod 1607 can penetrate the support base 1601 to push the pin 1605. In this utility model, the telescopic element 1606 is a cylinder; of course, the telescopic element 1606 can also be replaced by a hydraulic cylinder or an electronic telescopic element, and the specific selection of the telescopic element 1606 can be determined according to the actual situation.

[0055] Of course, when the equipment cost and subsequent processing of the compressor pump body are not considered, and the entire structure of the second lifting mechanism 16 is directly set on the accompanying tooling plate 17, the pushing structure can be directly installed on the accompanying tooling plate 17; when the pushing structure is set on the accompanying tooling plate 17, one pushing structure can be directly used in this utility model. At this time, the output end of the telescopic element 1606 can be directly fixedly connected to the pin 1605, and the insertion and withdrawal of the pin 1605 can also be realized.

[0056] In this utility model, such as Figure 8 , Figure 9 , Figure 10 As shown, in order to ensure the vertical movement of the limiting block seat plate 9, an mounting plate 4 is installed on all four columns, and the mounting plate 4 is located above the limiting block seat plate 9. Multiple guide sleeves 5 are installed on the mounting plate 4, and guide posts 6 are installed through the multiple guide sleeves 5. The multiple guide posts 6 can move up and down within the guide sleeves 5, and the limiting block seat plate 9 is installed at the lower end of the multiple guide posts 6. In order to facilitate the driving of the limiting block seat plate 9 to move up and down, a telescopic element 2 7 is also installed on the mounting plate 4. The telescopic element 2 7 extends downward through the mounting plate 4 and is fixed to the limiting block seat plate 9, so that the telescopic element 2 7 drives the limiting block seat plate 9 to move synchronously while extending and retracting, thereby realizing the driving of the limiting block seat plate 9.

[0057] In this invention, the cooperation between the guide post 6 and the guide sleeve 5 not only allows the limiting block seat plate 9 to move smoothly up and down during its vertical movement, but also ensures that the limiting block seat plate 9 remains in a straight line throughout its vertical movement. Since the extension stroke of the telescopic element 7 is fixed, even if the guide post 6 is not equipped with a limiting structure, it will not cause the guide post 6 to detach from the guide sleeve 5. Furthermore, in this invention, the telescopic element 7 is a cylinder. Of course, the telescopic element 7 can also be replaced by a hydraulic cylinder or an electronic telescopic element, and the specific selection of the telescopic element 7 can be determined according to the actual situation.

[0058] To facilitate the installation of the positioning sleeve 13, a guide shaft 10 is vertically inserted through the limiting block seat plate 9. The central axis of the guide shaft 10 is collinear with the central axis of the positioning sleeve 13, and the guide shaft 10 can slide up and down on the limiting block seat plate 9. The positioning sleeve 13 is fixedly installed at the lower end of the guide shaft 10. To prevent the guide shaft 10 from falling off the limiting block seat plate 9, a fixing block 12 is provided at the upper end of the guide shaft 10. The diameter of the fixing block 12 is larger than the diameter of the through hole on the limiting block seat plate 9 through which the guide shaft 10 passes, effectively preventing the guide shaft 10 from detaching from the limiting block seat plate 9 due to its own weight. A compression sleeve is also fitted on the guide shaft 10. Spring 11, one end of compression spring 11 is pressed against positioning sleeve 13, and the other end of compression spring 11 is pressed against limiting block seat plate 9. The positioning sleeve 13 can be pushed downward by the elastic force of compression spring 11. When positioning sleeve 13 is pressed against the crankshaft of compressor pump body, positioning sleeve 13 can be kept stable by the elastic force of compression spring 11. When the crankshaft of compressor pump body is lifted upward, positioning sleeve 13 pushes compression spring 11 to compress, so that positioning sleeve 13 can move up and down stably. At the same time as positioning sleeve 13 moves upward, guide shaft 10 moves upward synchronously, thereby ensuring that the upward displacement of positioning sleeve 13 is more accurate.

[0059] In this utility model, when multiple columns are mounted on the mounting plate 4, the displacement sensor 8 can be directly mounted on the mounting plate 4. At this time, since the upper end of the guide shaft 10 extends upward through the limiting block seat plate 9, and the upper end of the guide shaft 10 is mounted with a fixing block 12, the positioning sleeve 13 will drive the guide shaft 10 and the fixing block 12 to move synchronously while moving. After the displacement sensor 8 is mounted on the mounting plate 4, the detection head of the displacement sensor 8 can correspond to the fixing block 12, so that the displacement sensor 8 has sufficient installation space and can also prevent the electrical connection line of the displacement sensor 8 from swinging during the up and down movement of the limiting block seat plate 9.

[0060] In this invention, to ensure that the compressor pump body is pressed and fixed on the accompanying tooling plate 17, two pressure plate limiting blocks 1401 are also installed on the limiting block seat plate 9. The two pressure plate limiting blocks 1401 are symmetrically arranged on the limiting block seat plate 9. At this time, the positioning sleeve 13 is located between the two limiting block seat plates 9. In order to ensure the stability between the two pressure plate limiting blocks 1401, a positioning pressure plate 1402 is also connected between the two pressure plate limiting blocks 1401. The positioning pressure plate 1402 and the pressure plate limiting blocks 1401 can be connected by plugging. Specifically, corresponding plugging slots are opened on the inner side of the two pressure plate limiting blocks 1401, and the two sides of the positioning pressure plate 1402 are inserted into the plugs of the two pressure plate limiting blocks 1401. The positioning plate 1402 is installed in the groove. Since the positioning sleeve 13 is located between the two limit block seats 9, an opening is provided on the positioning plate 1402 for the positioning sleeve 13 to pass through in order to ensure the up and down movement of the positioning sleeve 13. The positioning plate 1402 is also equipped with a clamping stud 1403 that clamps the compressor pump body. The clamping end of the clamping stud 1403 is adapted to the surface of the compressor pump body. When the telescopic element 7 pushes the limit block seat 9 to move downward, the limit block seat 9 drives the pressure plate limit block 1401, the positioning plate 1402, and the clamping stud 1403 to move downward together, so that the clamping stud 1403 is pressed against the compressor pump body, thereby clamping and fixing the compressor pump body on the accompanying tooling plate 17.

[0061] In this utility model, in order to ensure the lifting of the accompanying tooling plate 17, such as Figure 4 As shown, the first lifting mechanism 15 includes a fixed plate 1506 supported on the frame 1 by support columns. Multiple sliding sleeves 1501 are mounted on the fixed plate 1506, and a lifting platform 1502 is mounted above the fixed plate 1506. The lifting platform 1502 has guide posts 1503 inserted into the sliding sleeves 1501, with the guide posts 1503 slidingly engaging with the sliding sleeves 1501. Simultaneously, a lifting element 1505 is also mounted on the fixed plate 1506. The output end of the lifting element 1505 is connected to the lifting platform 1502, and the lifting of the lifting platform 1502 is driven by the lifting of the lifting element 1505. The lifting platform 1502 also has positioning pins 1504 that engage with positioning holes 1703 on the accompanying tooling plate 17. There are at least two positioning pins 1504, and the multiple positioning pins 1504 are symmetrically arranged on the lifting platform 1502.

[0062] To ensure that the positioning hole 1703 on the tooling plate can accurately correspond to the positioning pin 1504 on the lifting platform 1502, a limiting structure is also installed on the fixed plate 1506. The limiting structure is located in front of the first lifting mechanism 15. When the accompanying tooling plate 17 with the compressor pump body is installed above the lifting platform 1502, the limiting structure restricts the tooling plate from moving forward. When the lifting platform 1502 is lifted by the lifting element 1505, the positioning pin 1504 on the lifting platform 1502 can be accurately inserted into the positioning hole 1703 on the tooling plate, thereby lifting the accompanying tooling plate 17.

[0063] Since the accompanying tooling plate 17 needs to be placed on the conveying track 2 to continue moving forward after the compressor pump body completes the axial clearance detection, the limiting structure needs to have a lifting function. The limiting structure in this utility model includes a second lifting element 1507 installed on the fixed plate 1506, and a roller 1508 is also installed at the output end of the second lifting element 1507. When the lifting element 1507 drives the roller 1508 to move upward, and the roller 1508 is higher than the accompanying tooling plate 17 located on the conveying track 2, the roller 1508 restricts the tooling plate from moving forward as it moves along the conveying track 2, thus facilitating the subsequent lifting of the accompanying tooling plate 17 by the lifting platform 1502; when the lifting element 1507 drives the roller 1508 to move downward, and the roller 1508 is lower than the accompanying tooling plate 17 located on the conveying track 2, the roller 1508 cannot restrict the tooling plate from moving forward as it moves along the conveying track 2, allowing the compressor pump body that has completed the axial clearance detection to continue moving forward on the conveying track 2 along with the accompanying tooling plate 17.

[0064] In this utility model, the lifting element 1505 and the lifting element 1507 are one of the following: a cylinder, a hydraulic cylinder, and an electronic telescopic rod. At the same time, the front of the first lifting mechanism 15 is based on the conveying direction of the conveying track 2, that is, the front of the lifting mechanism is the side of the first lifting mechanism 15 that is closer to the output end of the conveying track 2.

[0065] Based on the aforementioned compressor pump body axial clearance detection equipment, this utility model also provides a production line including the compressor pump body axial clearance detection equipment, such as... Figure 1 As shown, the production line also includes conveyor rails 2 located on both sides of the first lifting mechanism 15. The two conveyor rails 2 are symmetrically arranged along the center of the accompanying tooling plate 17, and the distance between the two conveyor rails 2 is less than the width of the accompanying tooling plate 17. After the accompanying tooling plate 17 is placed on the two conveyor rails 2, the conveyor rails 2 can transport the accompanying tooling plate 17 forward, which ensures that the compressor pump body to be axially inspected is transported to the top of the first lifting mechanism 15, and also ensures that the compressor pump body after the axial clearance inspection is completed is transported to the next processing station.

[0066] When it is necessary to detect the axial clearance of the compressor pump body, the support pin 1701 on the accompanying tooling plate 17 and the saddle frame 1702 are used to connect the support pin 1701 on the compressor pump body to the silencing cavity on the compressor pump body, and the cylinder seat of the compressor pump body is supported on the saddle frame 1702, so that the compressor pump body is stably installed on the accompanying tooling plate 17. The accompanying tooling plate 17 with the compressor pump body installed is placed on two conveying rails 2. Through the conveying rails 2, the accompanying tooling plate 17 with the compressor pump body installed moves to the top of the lifting platform 1502. During this process, the lifting element 2 1507 drives the roller 1508 to move upward, so that the roller 1508 is higher than the accompanying tooling plate 17. After the accompanying tooling plate 17 enters the top of the first lifting mechanism 15, the accompanying tooling plate 17 is blocked by the roller 1508 and cannot move forward, so that the accompanying tooling plate 17 is precisely aligned with the first lifting mechanism 15.

[0067] Next, the lifting element 1505 in the first lifting mechanism 15 extends, driving the lifting platform 1502 upward, causing the positioning pin 1504 on the lifting platform 1502 to insert into the positioning hole 1703 of the accompanying tooling plate 17. Then, the lifting element 1505 continues to extend, pushing the lifting platform 1502 upward, thereby causing the accompanying tooling plate 17 to disengage from the conveying track 2, and causing the compressor pump body mounted on the accompanying tooling plate 17 to move upward synchronously; once the compressor pump body is lifted by the lifting element 1505... When fully lifted, the telescopic element 2 7 drives the limit block seat plate 9 to move downward. At the same time, the limit block seat plate 9 moves downward, driving the pressure plate limit block 1401, the positioning pressure plate 1402, and the clamping stud 1403 to move downward synchronously, so that the clamping stud 1403 presses against the compressor pump body, and the compressor pump body is pressed and fixed on the accompanying tooling plate 17. At the same time that the clamping stud 1403 presses against the compressor pump body, the positioning sleeve 13 is pressed against the crankshaft of the compressor pump body by the elastic force of the compression spring 11, so that the compressor pump body enters the test state.

[0068] Next, the telescopic element 1606, which pushes the pin 1605 into the support base 1601, extends. Simultaneously, the extension of the telescopic element 1606 drives the push rod 1607, which is fixed to it, to move synchronously. The push rod 1607, in turn, pushes the pin 1605 into the support base 1601. During insertion, the wedge-shaped surface of the pin 1605 pushes the lifting pin 1602 upward. Simultaneously, the lifting pin 1602 drives the top sleeve 1603 upward. The upward movement of the top sleeve 1603 lifts the counterweight on the compressor pump body and the crankshaft on the compressor pump body, causing the crankshaft on the compressor pump body to move upward. During this upward displacement, the crankshaft pushes the positioning sleeve 13 upward, compressing the spring 11. Simultaneously, the upward displacement of the positioning sleeve 13 drives the guide shaft 10 and the fixing block 12 to move upward synchronously. The displacement sensor 8 detects the upward displacement of the fixing block 12, thereby obtaining the axial clearance of the compressor pump body.

[0069] After the axial clearance of the compressor pump body is detected, the telescopic element 1606, which pushes the pin 1605 into the support base 1601, retracts. Simultaneously, the retraction of the telescopic element 1606 drives the push rod 1607, which is fixed to it, to move synchronously, causing the push rod 1607 to lose its pushing force on the pin 1605. Then, the telescopic element 1606 extends, pushing the pin 1605 out of the support base 1601. Simultaneously, the extension of the telescopic element 1606 drives the push rod 1607, which is fixed to it, to move synchronously. As the push rod 1607 moves, it pushes the pin 1605 gradually out of the support base 1601, causing the lifting pin 1602 to lose its lifting force. After the pin 1605 exits the support base 1601, the element used to push the pin... 1605 retracts the telescopic element 1606 inside the support base 1601. At the same time, the telescopic element 1606 retracts and drives the push rod 1607 fixed to it to move synchronously, so that the push rod 1607 loses its push on the pin 1605. At the same time, the telescopic element 7 retracts and drives the limit block seat plate 9 to move upward. At the same time, the limit block seat plate 9 drives the pressure plate limit block 1401, the positioning pressure plate 1402, and the clamping stud 1403 to move upward synchronously, so that the clamping stud 1403 loses its clamping on the compressor pump body, and the positioning sleeve 13 loses its clamping on the crankshaft on the compressor pump body. The compression spring 11 pushes the positioning sleeve 13 downward through its own elastic force, so that the positioning sleeve 13 drives the guide shaft 10 and the fixing block 12 to reset.

[0070] Finally, lifting element 1505 retracts, causing lifting platform 1502 to move downwards, which in turn causes the accompanying tooling plate 17 on lifting platform 1502 to move downwards synchronously. When the accompanying tooling plate 17 enters the conveyor track 2, lifting element 1505 continues to retract, causing lifting platform 1502 to continue moving downwards. Positioning pin 1504 on lifting platform 1502 exits the positioning hole 1703 on accompanying tooling plate 17. At this time, the accompanying tooling... Plate 17 is stored on conveying track 2, and the lifting platform 1502 is separated from the accompanying tooling plate 17. At the same time, the second lifting element 1507 drives the roller 1508 to move downward. When the roller 1508 is lower than the accompanying tooling plate 17 located on the conveying track 2, the second lifting element 1507 stops retracting. During the process of the accompanying tooling plate 17 moving along the conveying track 2, the roller 1508 can no longer restrict the tooling plate from moving forward, so that the compressor pump body can continue to move forward on the conveying track 2 after the axial clearance is detected.
