Description

Technical Field

[0001] This invention relates to the field of valve sleeve testing technology, specifically a valve sleeve continuity testing device. Background Technology

[0002] A compressor solenoid valve typically consists of a solenoid coil, a stationary iron core, a moving iron core, a valve core, and a valve sleeve. The valve sleeve is a precision tubular part that encloses the valve core and guides its reciprocating motion. The diameter of the valve sleeve mounting part directly affects the fitting clearance.

[0003] Currently, the industry commonly uses ring gauges for passability inspection of the diameter of each step in the valve sleeve mounting section. The specific procedure involves selecting a ring gauge of the corresponding nominal size and qualitatively judging each step surface as either "go" or "no-go". However, because the mounting section has a stepped structure, each step requires a ring gauge with a different inner diameter for inspection. Operators must frequently change ring gauges and repeatedly clamp or rotate the valve sleeve, making the inspection process cumbersome and time-consuming, which is difficult to meet the needs of mass production lines. Summary of the Invention

[0004] The purpose of this invention is to provide a valve sleeve continuity detection device that detects the valve sleeve body through the action of a moving part and a ball, thereby solving the problem of low detection efficiency in the prior art.

[0005] To address the problems of existing technologies, this invention provides a valve sleeve continuity detection device for batch detection of valve sleeve body dimensions, including... Machine tool; The detection component, located on one side of the top of the machine, is used to detect the dimensions of the mounting portion of the valve sleeve body; A clamping assembly, located on the other side of the top of the machine tool, is used to clamp the valve sleeve body and rotate it. A support assembly, positioned between the detection assembly and the clamping assembly, is used to support the valve sleeve body; The feeding mechanism is located directly above the support assembly and is used to continuously feed the valve sleeve body one by one. The support assembly includes a support platform disposed above the machine base and capable of reciprocating between the working position and the unloading position. The detection assembly includes a first drive mechanism mounted on the top of the machine base and a detection unit disposed on the top of the first drive mechanism. The detection unit includes several movable parts capable of synchronous movement. Each movable part has a connecting rod, and a ball is rotatably disposed at the end of the connecting rod.

[0006] Preferably, a pressure sensor is also provided between the moving part and the connecting rod.

[0007] Preferably, the detection unit further includes a support disk disposed on the first drive mechanism, and the support disk has a plurality of guide grooves that slide in cooperation with the moving part, and a capacitive sensor is also provided between the moving part and the guide grooves.

[0008] Preferably, the detection component further includes a first rotating mechanism for driving multiple moving parts to move synchronously. The first rotating mechanism includes a rotating disk rotatably mounted on a support disk. The rotating disk has an arc-shaped groove corresponding to the moving part, which extends toward the center of the rotating disk. The outer ring of the rotating disk is provided with a toothed ring.

[0009] Preferably, the first rotating mechanism further includes a second rotating drive component fixed on the support plate, the output end of the second rotating drive component being connected to a first gear, the first gear meshing with a gear ring.

[0010] Preferably, the support platform has a placement groove, which is a "V" shaped groove, and the groove wall is also provided with a flexible pad.

[0011] Preferably, the clamping assembly includes a second drive mechanism disposed on the machine base and a clamping unit disposed on the second drive mechanism. The clamping unit includes a movable plate and a connecting sleeve. The connecting sleeve has a plurality of clamping claws that can move synchronously for clamping the valve sleeve body. Each clamping claw is connected to a first transmission rod hinged to the connecting sleeve. The clamping unit also includes a synchronous drive mechanism for driving the plurality of clamping claws to move synchronously.

[0012] Preferably, the clamping assembly further includes a second rotating mechanism disposed outside the moving plate for driving the connecting sleeve to rotate.

[0013] Preferably, the feeding mechanism includes a hopper for storing valve sleeve bodies disposed on a support assembly, wherein a distributing wheel is rotatably disposed in the hopper to allow valve sleeve bodies to enter one by one onto the support assembly, the distributing wheel having a material groove, and a fifth rotary drive component is provided on the back of the hopper.

[0014] Preferably, the support assembly further includes a second telescopic drive component vertically disposed at the bottom of the machine platform, the output end of the second telescopic drive component being connected to a lifting plate, and the top of the lifting plate being connected to the bottom of the support platform via a rod.

[0015] The advantages of this invention compared to the prior art are: 1. This application utilizes a synchronously movable component, which includes a connecting rod and a ball bearing. During testing, the ball bearing maintains contact with the surface of the valve sleeve body's mounting portion, and the diameter of the valve sleeve body can be directly determined based on the positional changes of the movable component. This structure enables continuous measurement of the diameter at different steps of the valve sleeve body, significantly improving testing efficiency.

Specifically, the valve sleeve body is placed in the hopper, and the valve sleeve body falls into the material trough under the action of gravity. As the material distribution wheel rotates, the valve sleeve body is sequentially transported to the placement slot on the support platform, thereby completing the automated feeding process of the valve sleeve body.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 8As shown, the present invention provides a valve sleeve continuity detection device for batch detection of the dimensions of valve sleeve bodies 2, including a machine base 1; a detection component 11, disposed on one side of the top of the machine base 1, for detecting the dimensions of the mounting portion of the valve sleeve body 2; a clamping component 12, disposed on the other side of the top of the machine base 1, for clamping and rotating the valve sleeve body 2; a support component 14, disposed between the detection component 11 and the clamping component 12 for supporting the valve sleeve body 2; and a feeding mechanism 13, disposed directly above the support component 14, for continuously feeding valve sleeve bodies 2 one by one. The support component 14 includes a support platform 141 disposed above the machine base 1 and capable of reciprocating between the working position and the unloading position. The detection component 11 includes a first drive mechanism 111 mounted on the top of the machine base 1 and a detection unit 112 disposed on the top of the first drive mechanism 111. The detection unit 112 includes several moving parts 1123 capable of synchronous movement. Each moving part 1123 has a connecting rod 1124, and a ball bearing 1125 is rotatably disposed at the end of the connecting rod 1124. The machine base 1 can also be equipped with a feeding mechanism, which can use a robotic arm to remove the valve sleeve body 2.

[0029] First, the feeding mechanism 13 continuously feeds the valve sleeve bodies 2 one by one onto the support platform 141 of the support assembly 14, at which point the support platform 141 is in the working position. The clamping assembly 12 then clamps and fixes the valve sleeve bodies 2, ensuring their stable position during the testing process. Subsequently, the first drive mechanism 111 in the testing assembly 11 drives the testing unit 112 to move, causing the ball bearing 1125 on the testing unit 112 to contact the mounting surface of the valve sleeve body 2. Since the moving parts 1123 can move synchronously, the diameter of the valve sleeve body 2 can be determined by detecting the position of each moving part 1123. During the testing process, the clamping assembly 12 can also drive the valve sleeve body 2 to rotate, thereby achieving continuous measurement at different circumferential positions and evaluating geometric parameters such as roundness. After the inspection is completed, the clamping assembly 12 releases the valve sleeve body 2, the support platform 141 moves from the working position to the unloading position, and sends out the valve sleeve body 2. Then the support platform 141 returns to the working position, and the feeding mechanism 13 sends in the next valve sleeve body 2. The above process is repeated to realize continuous batch inspection of the valve sleeve body 2.

[0030] A pressure sensor is also provided between the moving part 1123 and the connecting rod 1124.

[0031] During testing, the ball 1125 contacts the mounting surface of the valve sleeve body 2, and the diameter and other dimensions are measured by the positional change of the moving part 1123. Simultaneously, a pressure sensor monitors the contact pressure between the ball 1125 and the valve sleeve body 2 in real time to aid in determining roundness. If the pressure sensor reading changes periodically during the uniform rotation of the valve sleeve body 2 driven by the clamping assembly 12, it reflects the roundness error of the mounting surface of the valve sleeve body 2.

[0032] The detection unit 112 also includes a support disk 1121 disposed on the first drive mechanism 111, and the support disk 1121 has a plurality of guide grooves 1122 that are slidably engaged with the moving member 1123, and a capacitive sensor is also provided between the moving member 1123 and the guide grooves 1122.

[0033] During testing, the ball 1125 contacts the mounting surface of the valve sleeve body 2, and the diameter of the valve sleeve body 2 can be obtained by measuring the position change of the moving part 1123 through the capacitive sensor.

[0034] The first drive mechanism 111 includes a first mounting plate 1111 mounted on the top of the machine base 1. A first lead screw 1112 is rotatably mounted on the first mounting plate 1111. A first guide rod 1114 is provided on the first mounting plate 1111. A support plate 1121 is connected to the first lead screw 1112 through a lead screw nut. The support plate 1121 is slidably connected to the first guide rod 1114. The first drive mechanism 111 also includes a first rotary drive member 1113 fixed on the first mounting plate 1111 for driving the first lead screw 1112 to rotate.

[0035] The first rotary drive 1113 in the detection assembly 11 drives the first lead screw 1112 to rotate, which in turn moves the support plate 1121 along the first guide rod 1114 via the lead screw nut. This causes the entire detection unit 112 to feed towards the valve sleeve body 2. The moving part 1123 slides along the guide groove 1122. A capacitive sensor located between the moving part 1123 and the guide groove 1122 collects displacement data in real time, thereby accurately obtaining the position of each moving part 1123 and calculating the diameter of the valve sleeve body 2 accordingly. Simultaneously, a pressure sensor located between the moving part 1123 and the connecting rod 1124 collects contact pressure data in real time. During the uniform rotation of the valve sleeve body 2 driven by the clamping assembly 12, if the pressure sensor value changes periodically, it can reflect the roundness error of the mounting surface of the valve sleeve body 2. After the detection is completed, the clamping assembly 12 releases the valve sleeve body 2, and the first rotary drive 1113 drives the first lead screw 1112 in the opposite direction, causing the detection unit 112 to return to its initial position.

[0036] The detection assembly 11 also includes a first rotating mechanism 1126 for driving multiple moving parts 1123 to move synchronously. The first rotating mechanism 1126 includes a rotating disk 11261 rotatably mounted on a support disk 1121. The rotating disk 11261 has an arc-shaped groove 11262 corresponding to the moving parts 1123, which extends towards the center of the rotating disk 11261. A toothed ring 11263 is provided on the outer ring of the rotating disk 11261. The first rotating mechanism 1126 also includes a second rotating drive 11265 fixed on the support disk 1121. The output end of the second rotating drive 11265 is connected to a first gear 11264, which meshes with the toothed ring 11263.

[0037] Based on the current specifications of the valve sleeve body 2 under test, the second rotation drive 11265 in the first rotation mechanism 1126 is activated, driving the first gear 11264 to rotate, which in turn drives the rotating disk 11261 to rotate via the gear ring 11263. The arc groove 11262 on the rotating disk 11261 pushes each moving part 1123 to move synchronously radially along the guide groove 1122, so that the measuring circumference diameter formed by the rolling ball 1125 matches the mounting diameter of the valve sleeve body 2.

[0038] The support platform 141 has a placement groove, which is a "V" shaped groove, and the groove wall is also provided with a flexible pad.

[0039] The "V"-shaped groove is used for radial positioning of the valve sleeve body 2. The groove wall is also equipped with a flexible pad to cushion the contact force and prevent scratches on the surface of the valve sleeve body 2. The flexible pad can be made of rubber or silicone.

[0040] The support assembly 14 also includes a second telescopic drive member 143 vertically disposed at the bottom of the machine base 1. The output end of the second telescopic drive member 143 is connected to a lifting plate 142. The top of the lifting plate 142 is connected to the bottom of the support platform 141 through a rod.

[0041] The second telescopic drive component 143 extends, driving the lifting plate 142 to rise, thereby placing the support platform 141 in the working position. This is used to receive the valve sleeve body 2. After the inspection is completed, the clamping assembly 12 releases the valve sleeve body 2, and the first drive mechanism 111 reverses its direction, causing the inspection unit 112 to return to its initial position. The second telescopic drive component 143 retracts, driving the lifting plate 142 to descend, causing the support platform 141 to move from the working position to the unloading position, and then the unloading mechanism sends the valve sleeve body 2 out. Subsequently, the second telescopic drive component 143 extends again, the support platform 141 returns to the working position, and the loading mechanism 13 sends in the next valve sleeve body 2. This process is repeated, thereby achieving continuous batch inspection of the valve sleeve body 2 and comprehensive measurement of its diameter and roundness.

[0042] The clamping assembly 12 includes a second drive mechanism 121 mounted on the machine base 1 and a clamping unit 122 mounted on the second drive mechanism 121. The clamping unit 122 includes a moving plate 1221 and a connecting sleeve 1223. The connecting sleeve 1223 has several clamping claws 1224 that can move synchronously to clamp the valve sleeve body 2. Each clamping claw 1224 is connected to a first transmission rod 1225 that is hinged to the connecting sleeve 1223. The clamping unit 122 also includes a synchronous drive mechanism for driving the multiple clamping claws 1224 to move synchronously. The clamping assembly 12 also includes a second rotation mechanism 123 mounted outside the moving plate 1221 for driving the connecting sleeve 1223 to rotate.

[0043] When the valve sleeve body 2 falls into the "V" shaped groove, the second drive mechanism 121 in the clamping assembly 12 drives the moving plate 1221 to move towards the valve sleeve body 2, so that the connecting sleeve 1223 approaches the valve sleeve body 2; the synchronous drive mechanism drives multiple clamping claws 1224 to move radially inward synchronously through the first transmission rod 1225, so as to center and clamp the valve sleeve body 2. During the process of the second rotation mechanism 123 in the clamping assembly 12 driving the connecting sleeve 1223 and the valve sleeve body 2 to rotate at a constant speed, if the pressure sensor value changes periodically, it can reflect the roundness error of the mounting surface of the valve sleeve body 2.

[0044] The feeding mechanism 13 includes a hopper 131 mounted on a support assembly 14 for storing valve sleeve bodies 2. A distributing wheel 132 is rotatably mounted in the hopper 131, allowing valve sleeve bodies 2 to enter one by one onto the support assembly 14. The hopper 131 is used for batch storage of valve sleeve bodies 2 to be tested. The hopper 131 has a receiving cavity capable of accommodating multiple valve sleeve bodies 2 arranged sequentially. The valve sleeve bodies 2 are automatically conveyed downwards to the distributing wheel 132 by gravity or a guiding structure. A material groove 1321 is provided on the distributing wheel 132, serving as a carrier for receiving and transferring the valve sleeve bodies 2. When a valve sleeve body 2 falls into the material groove 1321, as the distributing wheel 132 rotates, the valve sleeve body 2 rotates with the distributing wheel 132 to the lower discharge position. A fifth rotary drive component 133 is located on the back of the hopper 131.

[0045] The operator places multiple valve sleeve bodies 2 sequentially into the hopper 131. Under gravity, the valve sleeve bodies 2 slide downwards along the guide channel of the hopper 131, with the lowest valve sleeve body 2 abutting against the outer edge of the distribution wheel 132. The fifth rotary drive 133 is activated, driving the distribution wheel 132 to rotate. The rotation of the distribution wheel 132 causes the valve sleeve body 2 to rotate through a certain angle. When the opening of the material trough 1321 faces downwards, the valve sleeve body 2 falls out of the material trough 1321 under gravity and accurately falls into the support assembly 14 below (specifically, the placement slot on the support platform 141). Each rotation of the distribution wheel 132 completes the loading of one valve sleeve body 2. Through the intermittent drive of the fifth rotary drive 133, continuous loading is achieved, ensuring that the testing device can perform continuous batch and automated testing of the valve sleeve bodies 2.

[0046] The side of the movable plate 1221 away from the connecting sleeve 1223 is connected to the support plate 1222 by a rod. The second rotating mechanism 123 includes a fourth rotating drive member 1233 fixed on the support plate 1222. The output end of the fourth rotating drive member 1233 is connected to a second gear 1232. The second rotating mechanism 123 also includes a third gear 1231 fixed on the connecting sleeve 1223. The third gear 1231 meshes with the second gear 1232.

[0047] The fourth rotary drive 1233 is activated. The output shaft of the fourth rotary drive 1233 drives the second gear 1232 to rotate, and the second gear 1232 drives the third gear 1231, which meshes with it, to rotate. The third gear 1231 is fixedly connected to the connecting sleeve 1223, so the connecting sleeve 1223, together with the internal clamping claw 1224 and the clamped valve sleeve body 2, rotates around its own axis. During the rotation, the pressure sensor in the detection assembly 11 monitors the change in contact pressure in real time, thereby determining the roundness error of the mounting surface of the valve sleeve body 2.

[0048] The synchronous drive mechanism includes a first telescopic drive member 1229 mounted on the outside of the support plate 1222 via a rod. The first telescopic drive member 1229 is a linear actuator (such as a cylinder or electric push rod) used to provide driving force for the radial movement of the gripper 1224. A moving rod 1228 is movably connected to the output end of the first telescopic drive member 1229. One end of the moving rod 1228 is connected to a moving disk 1227, and a second transmission rod 1226 is hinged to the moving disk 1227. The end of the second transmission rod 1226 is connected to one end of the first transmission rod 1225.

[0049] When the valve sleeve body 2 needs to be clamped, the first telescopic drive 1229 is activated and extends, pushing the moving rod 1228 to move axially toward the valve sleeve body 2. The moving rod 1228 drives the moving disk 1227 to move forward synchronously. The hinge point on the moving disk 1227 moves forward, pushing the second transmission rod 1226. The second transmission rod 1226 converts the axial thrust into a radial component force on the first transmission rod 1225, causing the first transmission rod 1225 to swing around its hinge point with the connecting sleeve 1223. Since multiple first transmission rods 1225 and clamping claws 1224 are evenly distributed along the circumference, and the linkage relationship between the second transmission rod 1226 and the first transmission rod 1225 is consistent, all clamping claws 1224 move radially inward synchronously, evenly clamping the outer circle of the valve sleeve body 2 from multiple directions, achieving centering clamping. When the valve sleeve body 2 needs to be released, the first telescopic drive 1229 retracts, driving the moving rod 1228 and the moving disk 1227 to move backward. The moving disk 1227 pulls the second transmission rod 1226, and the second transmission rod 1226 drives the first transmission rod 1225 to swing in the opposite direction, causing the clamping claw 1224 to move radially outward in sync, thus releasing the valve sleeve body 2.

[0050] The second drive mechanism 121 includes a second mounting plate 1211 fixed to the top of the machine base 1. A second lead screw 1214 is rotatably mounted on the second mounting plate 1211. The second mounting plate 1211 also has a second guide rod 1213. A third rotary drive component 1212 is connected to the second mounting plate 1211. The output end of the third rotary drive component 1212 is connected to the second lead screw 1214. The second lead screw 1214 is connected to a moving plate 1221 through a lead screw nut. The moving plate 1221 is slidably connected to the second guide rod 1213.

[0051] When the valve sleeve body 2 needs to be clamped, the control system (existing technology) issues a command to activate the third rotary drive 1212. The output shaft of the third rotary drive 1212 drives the second lead screw 1214 to rotate in a predetermined direction. The second lead screw 1214 and the lead screw nut fixed on the moving plate 1221 form a helical transmission pair, converting the rotational motion into the linear motion of the moving plate 1221. Due to the constraint of the second guide rod 1213 on the moving plate 1221, the moving plate 1221 can only move smoothly along the axial direction and will not deflect circumferentially. The moving plate 1221 drives the clamping unit 122 (including the connecting sleeve 1223, clamping claw 1224, etc.) mounted on it to move together towards the valve sleeve body 2 until the clamping claw 1224 reaches the predetermined clamping position. At this time, the synchronous drive mechanism is activated, causing the clamping claw 1224 to radially clamp the valve sleeve body 2. When the test is completed and the valve sleeve body 2 needs to be released, the synchronous drive mechanism first releases the clamping claw 1224, and then the third rotary drive component 1212 rotates in the opposite direction, driving the second lead screw 1214 to reverse, causing the moving plate 1221 to move away from the valve sleeve body 2 along the second guide rod 1213, driving the entire clamping unit 122 to return to its original position, making room for the next loading and unloading.

[0052] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
