Abstract
Description
Technical Field
[0001] This utility model relates to a device for measuring the upturn height of a warped workpiece, belonging to the field of automated detection technology. Background Technology
[0002] In the compressor manufacturing industry, the manufacturing precision of valve plates is crucial to ensuring the overall performance of the compressor. Take a warped valve plate as an example: one end of the valve plate has a hole for assembly, while the other end is warped upwards. This design aims to meet specific fluid dynamic requirements within the compressor. However, the height of the warp of the valve plate is a critical dimensional parameter, and its accuracy must be strictly controlled within ±0.1 mm. This tolerance directly affects the compressor's operating efficiency, sealing performance, and overall reliability. If the warp height deviates from this tolerance range, it may lead to decreased compressor performance, increased energy consumption, or even malfunction.
[0003] Currently, a common method for detecting the upward tilt of valve plates is a combination of a dial indicator and a fixed block. The operation of this method is relatively straightforward: first, the valve plate to be tested is securely fixed to the bottom of a specially designed fixed block using bolts, ensuring the stability of the valve plate's position during testing; then, a dial indicator is installed on the fixed block, with its probe passing through a pre-drilled hole in the block to directly contact the warped end of the valve plate for measurement. This testing method relies on the high-precision reading capability of the dial indicator, which can accurately reflect the actual deviation in the upward tilt of the valve plate.
[0004] While this dial indicator and fixed block-based inspection method is technically feasible, and the required fixtures are relatively simple to construct, easy to operate and maintain, the manual operation required for each valve is time-consuming and makes rapid batch inspection difficult. Therefore, in actual production, only sampling inspection is typically used, inspecting only valve plates from a portion of the production batches. Although this approach reduces inspection costs to some extent, it also means that the dimensional compliance rate of all production components cannot be comprehensively and accurately grasped; estimations must be made based on limited inspection data. While this estimation method reflects the overall quality trend to some extent, it is clearly insufficient to ensure that each batch of valve plates meets stringent tolerance requirements.

In addition, the orientation adjustment mechanism, in conjunction with the material chute, enables the workpiece to automatically complete orientation adjustment during the conveying process without the need for additional processing steps.
[0016] Furthermore, the measuring mechanism also includes a side positioning drive cylinder, which is disposed on one side of the material slide groove. The push rod of the side positioning drive cylinder can pass through the side wall of the material slide groove to hold and position the workpiece from one side.
[0017] The beneficial effect of adopting the above-mentioned further solution is that when the push rod of the side positioning drive cylinder extends, it can pass through the side wall of the sliding groove and firmly hold the workpiece in place from one side, ensuring that the workpiece will not shift or shake during the inspection process, thereby greatly improving the accuracy and reliability of the measurement.
[0018] Furthermore, the switch mechanism includes a switch drive cylinder, a movable tongue rail, a first switch and a second switch. The switch drive cylinder is driven to the tongue rail.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and do not imply any priority in order or any specific technical meaning. Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).
[0032] When interpreting the description of this application, it should be clarified that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating directions or positional relationships, are based on the perspective and layout shown in the accompanying drawings. They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.
[0033] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0034] In this embodiment, with Figure 6 and Figure 7 The working process and working principle of the upward tilt height measuring device of this utility model will be explained by taking the valve plate 10 shown as an example. Figure 6 As shown, one end of the valve plate 10 is upturned, and the other end is provided with a positioning hole. One side of it is concave, and the other side is convex. The concave side is set as the front side, the convex side as the back side, the upturned end as the front end, and the end with the positioning hole as the rear end.
[0035] like Figures 1-5 As shown, a device for measuring the upward tilt height of a warped workpiece includes a support plate 1 and a sliding groove 3 disposed on the support plate 1. It also includes a direction adjustment mechanism 5, a measuring mechanism 7, and a switch mechanism 9 disposed along the sliding groove 3. The direction adjustment mechanism 5 detects the orientation of the workpiece and rotates the workpiece to a predetermined orientation based on the detection result. The measuring mechanism 7 includes a pressure rod 701, a positive positioning drive cylinder 702, and a laser sensor 703 for measuring the upward tilt height of the workpiece. The positive positioning drive cylinder 702 can drive the pressure rod 701 to move. The laser sensor 703 is disposed below the sliding groove 3, and the bottom of the sliding groove 3 has a through slot for the laser beam to pass through. The switch mechanism 9 is connected to the outlet of the sliding groove 3 and is used to divert the measured workpiece.
[0036] More specifically, see reference Figure 1 As shown, the upward tilt height measuring device further includes a first partition door 4, a second partition door 6, and a third partition door 8. The first partition door 4 is located at the rear end of the direction adjustment mechanism 5 and is used to control the timing of the workpiece entering the direction adjustment mechanism 5. The second partition door 6 is located between the direction adjustment mechanism 5 and the measuring mechanism 7 and is used to control the timing of the workpiece being conveyed to the measuring mechanism 7. The third partition door 8 is located at the front end of the measuring mechanism 7 and is used to control the timing of the workpiece leaving the measuring mechanism 7. Each of the first partition door 4, the second partition door 6, and the third partition door 8 includes a door body and a switch drive cylinder, the switch drive cylinder being used to control the movement of the door body.
[0037] The material chute 3 is inclined, and the valve plate 10 can continue to move along the preset inclined path by its own gravity until it reaches the predetermined position or performs the next step of processing.
[0038] like Figure 3 As shown, the direction adjustment mechanism 5 includes a turntable 501, a rotary drive cylinder 502, and a detection sensor for detecting the workpiece direction. The detection sensor is mounted on top of the turntable 501 (not shown in the figure) via a bracket. The rotary drive cylinder 502 drives the turntable 501 to rotate. The upper surface of the turntable 501 has a groove, and the turntable 501 is located on the conveying path of the material chute 3. When the first material gate 4 is opened, the valve plate 10 moves into the groove of the turntable 501. At this time, the detection sensor detects the front-back direction of the valve plate 10. If the detection result shows that the front-back direction of the valve plate 10 does not match the preset correct direction, the system will immediately start the rotary drive cylinder 502. Under the drive of the rotary drive cylinder 502, the turntable 501 will rotate the valve plate 10 by 180 degrees, thereby realizing the reversal of the front-back direction of the valve plate 10. The embodiments of this utility model do not limit the type of the detection sensor. The detection sensor can be an image recognition sensor, a laser displacement sensor, or a photoelectric sensor. As long as the detection sensor can realize the direction detection function, it should be within the protection scope of this utility model.
[0039] like Figure 4 As shown, the measuring mechanism 7 also includes a side positioning drive cylinder 704, which is disposed on one side of the sliding groove 3. The push rod of the side positioning drive cylinder 704 can pass through the side wall of the sliding groove 3 to hold the workpiece in place from one side. When the push rod of the side positioning drive cylinder 704 extends, it can pass through the side wall of the sliding groove 3 and firmly hold the workpiece in place from one side, ensuring that the workpiece will not shift or shake during the inspection process, thereby greatly improving the accuracy and reliability of the measurement.
[0040] like Figure 5As shown, the switch mechanism 9 includes a switch drive cylinder 901, a movable tongue rail 902, a first switch 903, and a second switch 904. The switch drive cylinder 901 is driven to move the tongue rail 902, and can drive the tongue rail 902 to move between the outlet of the material chute 3 and the first switch 903, or the switch drive cylinder 901 can drive the tongue rail 902 to move between the outlet of the material chute 3 and the second switch 904. The switch mechanism 9 can intelligently guide qualified and unqualified products to different paths based on the measurement results of the workpiece's upward tilting height, allowing the diversion path to be adjusted according to actual needs. For example, the first switch 903 can be used for subsequent processing or packaging of qualified products, while the second switch 904 can be used for the recycling or reprocessing of unqualified products.
[0041] The detection sensor is mounted on top of the turntable 501 via a bracket.
[0042] The upward tilt height measuring device also includes a sensor (not shown in the figure), which is located above the measuring station of the material chute 3 and can detect whether the workpiece has reached the measuring position.
[0043] The method for measuring the upward tilt height of the warped valve plate 10 using the upward tilt height measuring device of this utility model is as follows:
[0044] First, the valve plates 10 need to be fed one by one to the first material gate 4 with the concave side facing upwards by the feeding mechanism.
[0045] Open the first material separation door 4 and close the second material separation door 6. The valve plate 10 slides into the groove of the turntable 501 of the direction adjustment mechanism 5, and then close the first material separation door 4.
[0046] The direction adjustment mechanism 5 detects the direction of the valve plate 10. If the upward end of the valve plate 10 is ahead and the end with the positioning hole is behind, the rotary drive cylinder 502 will not start. At this time, the second partition door 6 will be opened to allow the workpiece to continue to be conveyed along the sliding groove 3. If the upward end of the valve plate 10 is behind and the end with the positioning hole is ahead, the rotary drive cylinder 502 will be started. Under the drive of the rotary drive cylinder 502, the turntable 501 will drive the valve plate 10 to rotate 180 degrees to the correct direction, and then the second partition door 6 will be opened to allow the workpiece to continue to be conveyed along the sliding groove 3.
[0047] When the workpiece moves along the slide chute 3 to the predetermined measurement position, the third partition gate 8 is first closed to prevent subsequent workpieces from entering the measurement area. Then, the second partition gate 6 is closed to prevent further workpieces from entering the measurement position. Above the measurement position, a sensor is installed to detect whether the workpiece has reached the measurement position. Once the sensor detects the workpiece's arrival, the system activates the positive positioning drive cylinder 702. The pressure rod 701 of the positive positioning drive cylinder 702 firmly holds the end of the workpiece with the positioning hole, ensuring the workpiece remains stable during measurement. Next, the system activates the side positioning drive cylinder 704, whose push rod holds the workpiece from one side, further ensuring the workpiece's horizontal positioning accuracy. After ensuring the workpiece is stable and accurately positioned, the system activates the laser sensor 703. The laser beam emitted by the laser sensor 703 passes through the through-slot at the bottom of the slide chute 3 and directly illuminates the workpiece, thereby measuring the workpiece's upward tilt height.
[0048] After the measurement is completed, the third separating door 8 is opened. If the valve plate 10 is qualified, the switch drive cylinder 901 can drive the tongue rail 902 to move between the outlet of the sliding chute 3 and the first branch 903. The qualified product moves from the first branch 903 to the subsequent processing step. If the valve plate 10 is unqualified, the switch drive cylinder 901 can drive the tongue rail 902 to move between the outlet of the sliding chute 3 and the second branch 904. The unqualified product moves from the second branch 904 to the recycling area.
[0049] This invention successfully achieves highly automated batch processing of workpieces from feeding to measurement, ensuring that each workpiece undergoes rigorous quality inspection, thereby significantly improving the overall quality and consistency of the products.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
