Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a multi-parameter measurement device for blades. Background Technology

[0002] In rotary compressor manufacturing, cylinders, pistons, and vanes are the core moving parts. The clearances, or step differences, between them directly affect the compressor's sealing performance, energy efficiency, and service life. In traditional production methods, these parts are often selected and matched in groups after manual measurement. This is not only inefficient and time-consuming per unit, but also susceptible to subjective errors, making it difficult to guarantee consistent fitting accuracy in mass production and failing to meet the demands for high-performance and miniaturized compressors. Therefore, automated measurement and matching machines based on automated detection, data matching, and precision mechanical transmission technologies have emerged as key equipment for solving the problem of precise component fitting in large-scale production.

[0003] The working process of this matching machine is as follows: the loading mechanism transports the cylinders, pistons, and blades to be matched to their respective precision testing stations. Using laser displacement sensors or high-precision image measurement systems, the key dimensions of each component are automatically collected and converted into digital signals. These key dimensions include the cylinder inner diameter, piston outer diameter, and blade thickness. Then, the control system analyzes the dimensional data of each component according to a preset step matching algorithm, such as "minimum clearance priority" or "group corresponding matching" algorithm, and quickly selects the cylinder, piston, and blade combinations that meet the fitting accuracy requirements. Finally, a robotic arm or transfer mechanism picks up the corresponding components according to the matching results and places them in the same assembly station or material box, completing the automatic matching.

[0004] The existing blade measurement station for the selection and matching machine suffers from errors in the blade placement position and the timing of the equipment's gripping, which cause errors in the blade transfer and measurement process. This affects the measurement accuracy and the efficiency of subsequent station connections. As a result, the blade measurement process suffers from insufficient automation, poor connection between links, limited production efficiency, and ultimately insufficient product quality stability. Utility Model Content

[0005] To address the problem of deviations in the automated connection between feeding and measurement processes in existing blade measuring equipment, which affects measurement accuracy and efficiency, this invention provides a multi-parameter blade measuring device.

[0006] The technical solution adopted in this utility model is:

[0007] A multi-parameter blade measurement device includes a blade feeding mechanism and a blade measuring mechanism, wherein the blade feeding mechanism is disposed on the feeding side of the blade measuring mechanism;

[0008] The blade feeding mechanism is provided with a feeding channel assembly, and a material picking mechanism is provided at one end of the feeding channel assembly near the blade measuring mechanism. The material picking mechanism includes a material picking track and a material picking gripper that can slide along the material picking track. The blade measuring mechanism is provided with a measuring transfer table, and a measuring push rod is provided on one side of the measuring transfer table.

[0009] The material gripper is used to pick up the blades placed on the feeding channel assembly and transport them to the measuring transfer platform by moving along the material picking track. The measuring push rod is used to connect to an external drive device and push the blades on the measuring transfer platform into the measuring position by translational motion.

[0010] Furthermore, the feeding channel assembly includes multiple arranged channel strips, with a material discharge space between adjacent channel strips. The bottom of the feeding channel assembly is provided with a top material mechanism, which includes a top material cylinder and a top material component connected to the top material cylinder. The top material component is used to lift the blades from the bottom of the feeding channel assembly through a lifting motion.

[0011] Furthermore, a sliding seat is connected between the picking gripper and the picking track, and the sliding seat is slidably engaged with the picking track. A gripper rotation mechanism and a gripper extension mechanism are connected between the picking gripper and the sliding seat. The gripper rotation mechanism is disposed on the sliding seat, and the picking gripper is disposed at the end of the gripper extension mechanism.

[0012] Furthermore, the feeding channel assembly is provided with a feeding and pushing mechanism, which includes a pushing block disposed at one end of the feeding channel assembly and a pull line connected to the pushing block at one end. The other end of the pull line is fixedly connected to the bottom of the feeding channel assembly. The pull line is connected to a pulley group located at the bottom of the feeding channel assembly, and the pulley group is connected to a pushing weight. The pushing block is used to apply a pushing force to the blade by the pull line under the gravity of the pushing weight.

[0013] Furthermore, the blade measuring mechanism is provided with a blade measuring tool mechanism, the measuring turntable is provided on one side of the blade measuring tool mechanism, and the blade measuring tool mechanism is provided on the other side opposite to the measuring turntable with a measuring push rod; the measuring push rod is used to connect to an external driving device and push the blade on the blade measuring tool mechanism out of the measuring position through translational movement.

[0014] Furthermore, the blade measuring mechanism is also equipped with a discharge transfer mechanism, which includes a discharge slide rail and a discharge moving seat mounted on the discharge slide rail. The discharge moving seat is equipped with a suction cup mechanism. The discharge mechanism is used to drive the suction cup mechanism to move along the discharge slide rail through the discharge moving seat and transfer the measured blade to the next station through the suction cup mechanism.

[0015] Furthermore, the feeding channel assembly of the blade feeding mechanism is also provided with a channel spacing adjustment mechanism. The channel spacing adjustment mechanism is provided with a first channel adjustment frame and a second channel adjustment frame. The first channel adjustment frame and the second channel adjustment frame are respectively connected to multiple channel strips of the feeding channel assembly in a staggered manner. A spacing adjustment rod and a spacing guide rod are connected through the first channel adjustment frame and the second channel adjustment frame. The spacing adjustment rod is connected to an adjustment handwheel.

[0016] The beneficial effects of this utility model are:

[0017] When the multi-parameter blade measuring device of this invention is in operation, the blade is first conveyed to the end near the blade measuring mechanism via the feeding channel assembly of the blade feeding mechanism. At this time, the picking claw of the picking mechanism slides along the picking track and grabs the blade on the feeding channel by positioning it at a preset position through the feeding channel assembly. Then, through the movement of the picking claw, the blade is smoothly transported to the measuring transfer platform of the blade measuring mechanism. This mechanism avoids the problems of blade placement deviation and inaccurate picking timing in the prior art by using the picking claw to grab the blade along the track. The measuring push rod on one side of the measuring transfer platform is connected to an external drive device, which accurately pushes the blade on the transfer platform into the measuring position through a smooth translational movement, ensuring that the blade is accurately positioned without deviation when entering the measuring stage. This mechanism automatically pushes the blade to the measuring position by the translational movement of the measuring push rod, thereby realizing the automated and smooth connection from blade feeding to the measuring stage and eliminating the sources of error in the transfer and measuring stages. The device of this invention effectively improves the automation and accuracy of blade measurement, solves the problem of poor connection between various links, improves production efficiency, avoids quality fluctuations caused by deviations, and significantly enhances the stability of product quality.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Example 1

[0032] A multi-parameter measurement device for blades, such as Figure 1 , Figure 2 and Figure 4 As shown, the device includes a blade feeding mechanism 1 and a blade measuring mechanism 2. The blade feeding mechanism 1 is located on the feeding side of the blade measuring mechanism 2. The blade feeding mechanism 1 is provided with a feeding channel assembly 11. A picking mechanism 12 is provided at one end of the feeding channel assembly 11 near the blade measuring mechanism 2. The picking mechanism 12 includes a picking track 121 and a picking gripper 122 that can slide along the picking track 121. A measuring transfer platform 21 is provided on the blade measuring mechanism 2. A measuring push rod 22 is provided on one side of the measuring transfer platform 21. The picking gripper 122 is used to pick up the blades placed on the feeding channel assembly 11 and transport them to the measuring transfer platform 21 by moving along the picking track 121. The measuring push rod 22 is used to connect to an external drive device and push the blades on the measuring transfer platform 21 into the measuring position by translational motion.

[0033] When the device is in operation, the blade to be measured first enters the feeding channel assembly 11 of the blade feeding mechanism 1, and is transported by the feeding channel assembly 11 to one end near the blade measuring mechanism 2. At this time, the picking mechanism 12 starts to operate. The picking claw 122 of the picking mechanism 12 slides along the preset picking track 121, and accurately picks up the blade on the channel with the help of the preset channel position of the feeding channel assembly 11, avoiding the problem of picking deviation. After picking up the blade, the picking claw 122 continues to move, transferring the blade to the measuring transfer table 21 of the blade measuring mechanism 2. The entire transportation process has high stability because the claw slides along the fixed track, effectively avoiding the defects of blade placement deviation and inaccurate picking timing control in the prior art. When the blade arrives at the measuring transfer table 21, the measuring push rod 22 on one side of the measuring transfer table 21 is externally driven by a device, such as a piston rod that can be connected to a cylinder. Under the action of the driving device, the measuring push rod 22 pushes the blade on the transfer table into the preset measuring position through a uniform and stable translational movement, ensuring that there is no positional deviation when the blade enters the measuring stage. This utility model replaces manual operation or unstable mechanical action with the directional movement of the mechanical structure. The material picking track 121 serves as a guide to ensure the positional accuracy of the gripper's grasping and transportation, and the translational movement of the measuring push rod 22 ensures the stability of the blade pushing. This achieves a smooth and automated connection from the feeding to the measuring stage of the blade, completely eliminating the source of error in the transfer and measuring stages. Ultimately, this device not only significantly improves the automation level of blade measurement but also greatly improves the measurement accuracy, effectively solving the problem of poor connection between various stages, thereby improving production efficiency. At the same time, it avoids quality fluctuations caused by positional deviations, significantly enhances the stability of product quality, and effectively solves the core problem of automation connection deviation in existing blade measuring equipment. It should be noted that, in order to realize the transfer motion of the picking gripper 122, a connection structure that can move with multiple degrees of freedom can be added to the picking gripper 122, such as a three-axis motion mechanism, a rotation mechanism, etc. The motion structure of the robot in the prior art can be directly applied to this utility model. As a preferred method, the motion structure of the picking gripper 122 is further proposed in the subsequent embodiments of this utility model, which will not be described in detail here.

[0034] Example 2

[0035] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 2 As shown, the feeding channel assembly 11 includes a plurality of arranged channel strips 111, and a material discharge space is provided between adjacent channel strips 111. The bottom of the feeding channel assembly 11 is provided with a top material mechanism, which includes a top material cylinder 112 and a top material component 113 connected to the top material cylinder 112. The top material component 113 is used to lift the blades from the bottom of the feeding channel assembly 11 through a lifting motion.

[0036] The unloading space is formed by multiple arranged channel strips 111 in the feeding channel assembly 11. The spacing between adjacent channel strips 111 is adapted to the blade size to ensure that the blade does not shift laterally within the unloading space. When the blade is conveyed by the feeding channel assembly 11 to a position close to the picking mechanism 12, the top-feeding mechanism at the bottom of the feeding channel assembly 11 starts. The top-feeding cylinder 112 of the top-feeding mechanism drives the top-feeding component 113 connected to it to perform a lifting movement. The top-feeding component 113 lifts upward from the bottom of the feeding channel assembly 11, slowly and smoothly lifting the blade in the unloading space until the blade rises to a gripping height adapted to the picking claw 122. Then, the top-feeding cylinder 112 stops, and the top-feeding component 113 maintains its current position, providing conditions for the picking claw 122 to grip the blade. The structure uses the lifting action of the top material mechanism to make the blades detach from the restriction of the material channel bar 111 and be at a fixed height before being grabbed. This avoids the problem that the picking claw 122 cannot accurately grab the blades because they are stacked in the material channel or are too low. At the same time, the design of multiple material channel bars 111 and the material release space further standardizes the placement posture of the blades in the material channel.

[0037] Example 3

[0038] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 2 As shown, a sliding seat 123 is connected between the picking gripper 122 and the picking track 121. The sliding seat 123 is slidably engaged with the picking track 121. A gripper rotation mechanism 124 and a gripper extension mechanism 125 are connected between the picking gripper 122 and the sliding seat 123. The gripper rotation mechanism 124 is disposed on the sliding seat 123, and the picking gripper 122 is disposed at the end of the gripper extension mechanism 125.

[0039] In this embodiment, when the device is in operation, after the blade is conveyed to the picking position, the picking gripper 122 moves smoothly along the picking track 121 via the sliding seat 123 to approach the blade. If the blade's posture deviates from the gripper's angle, the gripper rotation mechanism 124 on the sliding seat 123 drives the gripper to adjust its angle, while the gripper extension mechanism 125 pushes the gripper to extend and clamp the blade. After clamping, the extension mechanism retracts, and the sliding seat 123 transports the blade along the track to the measurement transfer station 21, where the blade is then placed smoothly through the coordinated movement of the rotation and extension mechanisms. This structure, through the cooperation of the sliding seat 123, the rotation, and the extension mechanism, allows the gripper to adjust its angle and extension length, improving the gripper's grasping accuracy and flexibility, preventing blade transport deviation or drop, ensuring the receiving accuracy of the subsequent measurement transfer station 21, and reducing sources of error before measurement.

[0040] Example 4

[0041] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 2 , Figure 3As shown, the feeding channel assembly 11 is provided with a feeding and pushing mechanism. The feeding and pushing mechanism includes a pushing block 114 disposed at one end of the feeding channel assembly 11 and a pull line 115 connected to the pushing block 114 at one end. The other end of the pull line 115 is fixedly connected to the bottom of the feeding channel assembly 11. The pull line 115 is connected to a pulley group 116 located at the bottom of the feeding channel assembly 11. The pulley group 116 is connected to a pushing weight 117. The pushing block 114 is used to apply a pushing force to the blade under the gravity pull of the pushing weight 117 through the pull line 115. During operation, after the blade is placed into the feeding space, the pull wire 115 at one end of the pusher block 114 passes around the bottom pulley group 116, and the other end is fixedly connected to the bottom of the mechanism. The gravity of the pusher weight 117 is converted into a continuous pushing force on the blade by the pusher block 114 through the pull wire 115 and the pulley group 116, pushing the blade to move smoothly towards the picking mechanism 12 in the feeding space, ensuring that the blade is always within the gripper's grasping range. This mechanism avoids the blade getting stuck or deviating in the material channel, reduces the gripper's waiting time, improves the continuity and efficiency of feeding, and at the same time avoids blade collision and wear, reducing the risk of quality fluctuations.

[0042] Example 5

[0043] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 4 As shown, the blade measuring mechanism 2 is equipped with a blade measuring tool mechanism 23. A measuring transfer table 21 is located on one side of the blade measuring tool mechanism 23, and a measuring push rod 24 is located on the other side of the blade measuring tool mechanism 23 opposite to the measuring transfer table 21. The measuring push rod 24 is used to connect an external drive device and push the blade on the blade measuring tool mechanism 23 out of the measuring position through translational movement. During operation, the blade is transported to the measuring transfer table 21 by the picking gripper 122, and the measuring push rod 22 pushes it into the blade measuring tool mechanism 23. After the parameter measurement is completed, the measuring push rod 24 on the other side of the measuring tool mechanism pushes the blade out of the measuring position. This structure solves the problem of poor connection when picking up the blade after measurement, avoids the low efficiency and accuracy interference of manual picking, improves the automation and efficiency of the measurement process, and provides conditions for subsequent material transfer.

[0044] Example 6

[0045] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 5As shown, the blade measuring mechanism 2 is also equipped with a material discharge and transfer mechanism. This mechanism includes a material discharge slide rail 25 and a material discharge moving seat 26 mounted on the slide rail 25. A suction cup mechanism 27 is mounted on the material discharge moving seat 26. The material discharge mechanism uses the material discharge moving seat 26 to drive the suction cup mechanism 27 along the slide rail 25, transferring the measured blade to the next workstation via the suction cup mechanism 27. During operation, after the measured blade is pushed out of the measuring device mechanism, the material discharge moving seat 26 moves along the slide rail 25, driving the suction cup mechanism 27 to move above the blade. The suction cup adsorbs the blade using negative pressure, and then moves along the slide rail with the moving seat to the next workstation. Finally, the adsorption stops, and the blade is placed stably. This structure uses negative pressure adsorption of the suction cup to fix the blade, and the sliding of the moving seat along the slide rail ensures a stable transfer path. It avoids damage or posture changes during blade transfer, ensuring blade integrity and posture accuracy in subsequent processes. It replaces manual transfer, reduces the risk of quality fluctuations, forms an automated process, and improves overall efficiency and quality stability.

[0046] Example 7

[0047] This utility model is based on the foregoing embodiments. In this embodiment, as shown in the foregoing embodiments... Figure 6 As shown, the feeding channel assembly of the blade feeding mechanism is also equipped with a channel spacing adjustment mechanism. The channel spacing adjustment mechanism is equipped with a first channel adjustment frame and a second channel adjustment frame. The first channel adjustment frame and the second channel adjustment frame are respectively connected to multiple channel strips of the feeding channel assembly in a staggered manner. A spacing adjustment rod and a spacing guide rod are connected through the first channel adjustment frame and the second channel adjustment frame. The spacing adjustment rod is connected to an adjustment handwheel.

[0048] When the width of the feed channel needs to be adjusted according to the blade size, the adjusting handwheel can be rotated to adjust the distance between the first and second feed channel adjusting frames via the spacing adjusting rod. This allows for translational adjustment of the spacing between adjacent feed channel strips under the guidance of the spacing guide rod, accommodating blades of different sizes. The spacing adjusting rod can be connected to the first and second feed channel adjusting frames via threads. Figure 6 As shown, the material channel strips connected to the first and second material channel adjustment frames are staggered in sequence. During adjustment, the spacing can be increased or decreased simultaneously, making adjustment more convenient and more adaptable to blades of different sizes.

[0049] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
