Description

Technical Field

[0001] This utility model relates to the field of air compressor valve plate processing technology, specifically to a device for detecting the flatness of air compressor valve plate processing. Background Technology

[0002] Air compressors, as core power sources in industrial production, pneumatic equipment, and automobile manufacturing, rely heavily on the precision of their internal key components for efficiency and operational stability. Among these, valve plates (intake and exhaust valves) are crucial for controlling gas intake and exhaust, and their flatness is a key indicator of the compressor's airtightness. If the flatness of the valve plates is substandard after machining (e.g., protrusions, depressions, or warping), the valve plates and valve seats cannot fit tightly, leading to gas leakage. This not only reduces the compressor's exhaust efficiency and increases energy consumption but also accelerates valve plate wear and fatigue fracture due to repeated impacts from leaking gas, shortening the compressor's lifespan and even causing equipment malfunctions and shutdowns. However, current air compressor valve plate flatness testing devices rely on manual operation for accuracy. Traditional testing often involves operators manually moving the valve plates with a lever gauge, relying entirely on experience to control the movement path. This can easily result in missed or repeated testing points, and hand tremors can cause unstable contact between the lever gauge probe and the valve plate surface, leading to testing errors. Therefore, we propose an air compressor valve plate flatness testing device. Utility Model Content

[0003] The purpose of this utility model is to provide a flatness detection device for air compressor valve plate processing, which has the advantage of automatic detection and solves the problem that the detection accuracy of current air compressor valve plate processing flatness detection devices depends on manual operation. Traditional detection is mostly carried out by the operator holding a lever gauge and manually moving the valve plate for detection. The movement path is entirely controlled by experience, which is prone to omission or repetition of detection points. In addition, hand tremors will cause unstable contact between the lever gauge probe and the valve plate surface, resulting in detection errors.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flatness detection device for air compressor valve plate processing, comprising a base, a groove on the top of the base, a threaded rod rotatably connected to the inner cavity of the groove via a bearing, a threaded sleeve threadedly connected to the outer surface of the threaded rod, a connecting plate fixedly connected to the top of the threaded sleeve via a bracket, an electric slide table mounted on the top of the connecting plate, a placement platform fixedly connected to the top of the electric slide table, a top plate fixedly connected to the top of the base via a bracket, a lever gauge provided at the bottom of the top plate, a motor fixedly connected to the right side of the base, the output shaft of the motor fixedly connected to the threaded rod, and second electric telescopic rods fixedly connected to the left and right ends of the top of the placement platform via brackets, a clamping plate fixedly connected to the other end of the second electric telescopic rod, and a pressure sensor provided between the clamping plate and the second electric telescopic rod.

[0005] Preferably, the top of the top plate has an opening, the top of the lever is fixedly connected to a first insert block, the first insert block penetrates the inner cavity of the opening, the back of the first insert block has an insertion hole, the top of the top plate is fixedly connected to a first electric telescopic rod, the front of the first electric telescopic rod is fixedly connected to a second insert block, and the second insert block is movably connected to the inner cavity of the insertion hole.

[0006] Preferably, a guide groove is provided at the bottom of the inner cavity of the groove, and a guide block is fixedly connected to the bottom of the threaded sleeve, and the guide block is slidably connected to the inner cavity of the guide groove.

[0007] Preferably, a toolbox is fixedly connected to the back of the base, and a partition is fixedly connected to the inner cavity of the toolbox.

[0008] Preferably, a battery box is fixedly connected to the right end of the back of the base, and a storage battery is fixedly connected to the inner cavity of the battery box.

[0009] Preferably, a PLC controller is fixedly connected to the right end of the front of the base. The output terminal of the PLC controller is electrically connected to the input terminals of the first electric telescopic rod, the second electric telescopic rod, the motor, and the electric slide. The input terminal of the PLC controller is electrically connected to the output terminal of the pressure sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The placement platform of this utility model serves as the supporting foundation for the valve plate. The second electric telescopic rods at both ends of its top are in conjunction with the clamping plate, which can automatically adjust the clamping range according to the size of the valve plate without manual operation. The pressure sensor between the clamping plate and the second electric telescopic rod can monitor the clamping force in real time and transmit the data to the PLC controller on the front of the base. This prevents the valve plate from deforming due to excessive clamping force or shifting due to insufficient force, ensuring that the valve plate remains stable and stress-free during the testing process. The threaded rod and threaded sleeve in the groove at the top of the base form a threaded transmission structure. The motor on the right side of the base drives the threaded rod to rotate, causing the threaded sleeve and the connecting plate at the top to move smoothly in a straight line. The guide block at the bottom of the threaded sleeve slides along the guide groove at the bottom of the groove, which can limit the rotation of the threaded sleeve with the threaded rod and ensure accurate movement path. The electric slide table at the top of the connecting plate can drive the placement platform to move back and forth. The two work together to allow the valve plate to move fully along the preset path. With the lever gauge at the bottom of the top plate, full coverage testing of the valve plate surface can be achieved, avoiding the experience error of manual movement and the omission of testing points.

[0011] 2. The socket at the top of the top plate of this utility model cooperates with the first plug at the top of the lever gauge, which can quickly complete the initial positioning of the lever gauge without repeated calibration; the first electric telescopic rod at the top of the top plate pushes the second plug into the socket on the back of the first plug, so as to firmly fix the lever gauge. When disassembling, the lever gauge can be easily removed by controlling the first electric telescopic rod to reset through the PLC controller. Compared with the traditional screw fixing, the disassembly and assembly time is greatly shortened, and it is especially suitable for the rapid replacement of lever gauges with different ranges.

Example

[0016] Please see Figure 1-3As shown, this utility model provides a flatness detection device for air compressor valve plate processing, including a base 1. A groove 3 is provided on the top of the base 1. A threaded rod 21 is rotatably connected to the inner cavity of the groove 3 through a bearing. A threaded sleeve 20 is threadedly connected to the outer surface of the threaded rod 21. A connecting plate 2 is fixedly connected to the top of the threaded sleeve 20 through a bracket. An electric slide table 19 is installed on the top of the connecting plate 2. A placement platform 4 is fixedly connected to the top of the electric slide table 19. A top plate 5 is fixedly connected to the top of the base 1 through a bracket. A lever gauge 9 is provided at the bottom of the top plate 5. A motor 16 is fixedly connected to the right side of the base 1. The output shaft of the motor 16 is fixedly connected to the threaded rod 21. A second electric telescopic rod 10 is fixedly connected to both the left and right ends of the top of the placement platform 4 through a bracket. A clamping plate 12 is fixedly connected to the other end of the second electric telescopic rod 10. A pressure sensor 17 is provided between the clamping plate 12 and the second electric telescopic rod 10. A guide groove 22 is provided at the bottom of the inner cavity of the groove 3. A guide block 23 is fixedly connected to the bottom of the threaded sleeve 20. The guide block 23 is slidably connected to the inner cavity of the guide groove 22.

[0017] In this technical solution, the platform 4 serves as the supporting foundation for the valve plate. The second electric telescopic rods 10 at its top left and right ends cooperate with the clamping plate 12, automatically adjusting the clamping range according to the valve plate size without manual operation. The pressure sensor 17 between the clamping plate 12 and the second electric telescopic rod 10 monitors the clamping force in real time and transmits the data to the PLC controller 11 on the front of the base 1. This prevents valve plate deformation due to excessive clamping force or displacement due to insufficient force, ensuring the valve plate remains stable and stress-free during testing. The threaded rod 21 and threaded sleeve 20 are located in the groove 3 at the top of the base 1. A threaded transmission structure is formed. The motor 16 on the right side of the base 1 drives the threaded rod 21 to rotate, which in turn drives the threaded sleeve 20 and the top connecting plate 2 to move smoothly in a straight line. The guide block 23 at the bottom of the threaded sleeve 20 slides along the guide groove 22 at the bottom of the groove 3, which can limit the rotation of the threaded sleeve 20 with the threaded rod 21 and ensure accurate movement path. The electric slide 19 at the top of the connecting plate 2 can drive the placement platform 4 to move back and forth. The two work together to enable the valve plate to move fully along the preset path. With the lever gauge 9 at the bottom of the top plate 5, full coverage detection of the valve plate surface can be achieved, avoiding the experience error of manual movement and the omission of detection points. Example

[0018] Based on Embodiment 1, this utility model is as follows: Figure 1-3As shown, the top of the top plate 5 has an insertion port 8, the top of the lever 9 is fixedly connected to a first insertion block 7, the first insertion block 7 passes through the inner cavity of the insertion port 8, the back of the first insertion block 7 has an insertion hole 18, the top of the top plate 5 is fixedly connected to a first electric telescopic rod 6, the front of the first electric telescopic rod 6 is fixedly connected to a second insertion block 13, the second insertion block 13 is movably connected to the inner cavity of the insertion hole 18, the back of the base 1 is fixedly connected to a toolbox 14, the inner cavity of the toolbox 14 is fixedly connected to a partition, the right end of the back of the base 1 is fixedly connected to a battery box 15, the inner cavity of the battery box 15 is fixedly connected to a battery, the right end of the front of the base 1 is fixedly connected to a PLC controller 11, the output end of the PLC controller 11 is electrically connected to the input end of the first electric telescopic rod 6, the second electric telescopic rod 10, the motor 16 and the electric slide table 19, and the input end of the PLC controller 11 is electrically connected to the output end of the pressure sensor 17.

[0019] The socket 8 at the top of the top plate 5 of this technical solution cooperates with the first plug 7 at the top of the lever gauge 9, which can quickly complete the initial positioning of the lever gauge 9 without repeated calibration. The first electric telescopic rod 6 at the top of the top plate 5 pushes the second plug 13 into the socket 18 on the back of the first plug 7 to achieve a firm fixation of the lever gauge 9. When disassembling, the lever gauge 9 can be easily removed by controlling the first electric telescopic rod 6 to reset through the PLC controller 11. Compared with the traditional screw fixation, the disassembly and assembly time is greatly shortened, which is especially suitable for the rapid replacement of lever gauges 9 with different ranges.

[0020] The working principle of this utility model is as follows: When using this device to test the flatness of an air compressor valve plate, firstly, place the valve plate to be tested on the top of the placement platform 4. Then, activate the second electric telescopic rod 10 on the placement platform 4 through the PLC controller 11 on the front of the base 1. The second electric telescopic rod 10 pushes the clamping plate 12 to move towards each other until the clamping plate 12 contacts the side of the valve plate. At this time, the pressure sensor 17 between the clamping plate 12 and the second electric telescopic rod 10 monitors the clamping force in real time and transmits the data to the PLC controller 11. The controller automatically adjusts the extension and retraction of the second electric telescopic rod 10 according to the preset safety force value to ensure that the valve plate is firmly fixed and without deformation. Next, install the lever gauge 9 and align the first insert 7 on the top of the lever gauge 9 with the top of the top plate 5. Insert the plug 8 into the top plate 5, and start the first electric telescopic rod 6 on the top plate 5 through the PLC controller 11. The first electric telescopic rod 6 pushes the second plug 13 forward and inserts it into the plug hole 18 on the back of the first plug 7, thus completing the firm fixation of the lever gauge 9 and adjusting the contact between the probe of the lever gauge 9 and the valve plate surface. Then, start the motor 16 on the right side of the base 1 through the PLC controller 11. The motor 16 drives the threaded rod 21 in the groove 3 to rotate. The threaded sleeve 20 drives the connecting plate 2 to move in a straight line under the cooperation of the guide block 23 and the guide groove 22. At the same time, the electric slide 19 on the top of the connecting plate 2 drives the placement platform 4 to move in another direction. The two work together to make the valve plate move smoothly along the preset path. The lever gauge 9 detects the flatness of the valve plate surface in real time.
