DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings of the embodiments of the present application. Figures 2-26 It should be apparent that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0062] Portable actuator output end limiting angle detection method:

[0063] (As Figure 2 ) The actuator 1 to be detected is coaxially righted, clamped, and fixedly constrained in the detection end of the portable actuator output end limiting angle detection device 2, that is, step S1, clamping.

[0064] Among them, the righting, clamping, and pressure limiting constraint clamping of the actuator 1 are the key to ensuring the detection accuracy of the actuator 1.

[0065] (Combined Figure 5 ) Specifically, step S1, clamping: the workpiece spindle 101 of the actuator 1 is coaxially interference-fitted with the detection end of the portable actuator output end limiting angle detection device 2, and the interference-fitting precision meets the fitting precision of a gap of 0.01 mm. After coaxial assembly, the coaxial detection function of the actuator 1 is realized.

[0066] Among them, the workpiece spindle 101 center counterbore 1012 is installed in the center of the outer convex detection spindle 2-6, and the end face of the workpiece spindle 101 is attached to the end face of the detection spindle 2-6. At this time, the workpiece rotation center is coaxial with the angle sensor 2-1 of the present application, reducing the coaxial error.

[0067] Furthermore, the workpiece fork support 103 of the actuator 1 needs to be supported and clamped.

[0068] In the above embodiment, further, to solve the supporting adjustment problem of the actuator 1 on the portable actuator output end limit angle detection device 2: Figure 7 Figure 8 In the above embodiment, further, to solve the supporting adjustment problem of the actuator 1 on the portable actuator output end limit angle detection device 2:

[0069] In step S1, the portable actuator output end limit angle detection device 2 has a positioning cylinder 2-8 and an eccentric positioning cylinder 2-7. The positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 are vertically screwed and fitted on the device end cover 2-5 described later.

[0070] To realize the installation and adjustment of the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 with a simple structure (as shown in Figures 7 to 9 ): A pair of end cover threaded holes 2-501 are made on the upper end face of the end cover 2-5; the end cover threaded holes 2-501 are located on the same side behind the workpiece fork support 103 and are arranged in line, and the end cover threaded holes 2-501 are arranged symmetrically left and right relative to the detection mandrel 2-6; the end cover threaded holes 2-501 are respectively screwed and fitted with the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7; the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 are used to support the workpiece fork support 103.

[0071] Among them, the eccentric positioning cylinder 2-7 is composed of a screw rod and an eccentric cylinder connected and installed by screwing, and the eccentric positioning cylinder 2-7 is vertically fixed and installed in the corresponding end cover threaded hole 2-501 of the end cover 2-5 by screwing the screw rod head.

[0072] In use, the outer cylindrical surface of the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 is attached to the vertical side wall behind the workpiece fork support 103 of the actuator 1, achieving the function of limiting the rotation of the workpiece fork support 103 around the workpiece mandrel 101 in the plane, especially supporting and installing the workpiece fork support 103. That is, by rotating the eccentric positioning cylinder 2-7, the workpiece fork support 103 of the actuator 1 is supported and clamped on the portable actuator output end limit angle detection device 2.

[0073] That is, the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 are rotated and adjusted, so that the rear side of the workpiece fork support 103 is attached to the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7, achieving the function of limiting the rotation of the workpiece fork support 103 around the mandrel in the plane.

[0074] It can be seen that the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7 are used in combination, which can finely adjust and support the workpiece fork support 103 of the actuator 1 to be detected, laying a foundation for accurate detection of the actuator 1.

[0075] ​After the workpiece fork support 103 is straightened and clamped, the red handle II 501 of the quick pressing fixture 5 is pressed down so that the two rubber pressing heads 502 of the quick pressing fixture 5 press the upper end surface of the workpiece fork support 103 to limit the overall movement of the actuator 1, that is, to limit the up and down movement of the actuator 1, leaving only the workpiece fork 102 of the actuator 1 to drive the workpiece core shaft 101 to rotate coaxially around the detection end of the limit angle detection device 2 at the output end of the portable actuator to wait for the detection of the limit angle of the actuator 1.

[0076] (like Figures 19 to 23 ) In the above embodiment, further: in order to solve how to quickly tighten and loosen the workpiece on the device: the quick pressing clamp 5 includes a clamp mounting seat 503, a pressing link 504, a handle II 501, a T-shaped pressing plate 505 and a rubber pressing head 502.

[0077] It should be noted that the fixture mounting base 503, the pressing link 504, and the handle II 501 are identical to the existing structure: the vertical quick clamp of the Goodhand brand, model GH-101B.

[0078] The quick pressing clamp 5 is fixedly mounted on the rear side of the end cover 2 - 5 via a clamp mounting seat 503 .

[0079] The clamp mounting base 503 is mounted with a pressing link 504 ; the pressing link 504 of the present invention is a four-link structure.

[0080] The operating end of the clamping connecting rod 504 is provided with a handle II 501. The handle II 501 is used for fast clamping and loosening switching of the clamp.

[0081] The difference from the existing structure is that the execution end of the clamping link 504 is fixedly connected to the T-shaped clamping plate 505 and drives the T-shaped clamping plate 505 to press vertically downward, so as to enable the T-shaped clamping plate 505 to perform vertical downward pressing and loosening actions.

[0082] The lower end surfaces of the symmetrical plates at the execution end of the T-shaped pressure plate 505 are respectively vertically fixed to the rubber pressing heads 502; when the rubber pressing heads 502 are pressed vertically downward, they are used to press and fix the workpiece fork support 103 of the actuator 1 to limit the up and down movement of the workpiece fork support 103.

[0083] The quick-pressing clamp 5 of the present invention is based on the existing Goodhand brand quick clamp, that is, the vertical quick-press clamp model GH-101B is modified as the basic structure, and is used to limit the longitudinal jump of the actuator 1. It is easy to operate and has reliable pressing.

[0084] (like Figures 11 to 16The structure of the applicable actuator 1 is that the actuator 1 is composed of a workpiece spindle 101, a workpiece fork 102 and a workpiece fork support 103.

[0085] The workpiece fork support 103 is fixedly installed on the end face of the end cover 2-5 of the portable actuator output end limit angle detection device 2 by using the fast pressure clamp 5, the positioning cylinder 2-8 and the eccentric positioning cylinder 2-7.

[0086] The workpiece spindle 101 and the workpiece fork 102 of the actuator 1 are rigidly connected as a whole in a concentric manner, and the workpiece spindle 101 and the workpiece fork 102 are rotatably supported and installed in the inner hole of the workpiece fork support 103 by using bearing members, and the workpiece spindle 101 and the workpiece fork 102 have a coaxial rotation function.

[0087] On this basis, the workpiece spindle 101 is provided with a central counterbore 1012 at the bottom end of the shaft body, and the central counterbore 1012 is used for coaxial clamping of the workpiece and the detection spindle.

[0088] The workpiece spindle 101 is provided with a positioning groove 1011 on the left and right sides of the bottom end respectively; the positioning groove 1011 is used for zero calibration of the workpiece.

[0089] The positioning groove 1011 is arranged symmetrically on the left and right sides with the central counterbore 1012 as the symmetric axis.

[0090] It can be seen that the aforementioned central counterbore 1012 is connected in a concentric interference fit with the top end of the detection spindle 2-6 shaft body of the portable actuator output end limit angle detection device 2; the positioning groove 1011 is used for positioning and inserting connection with the positioning end 301 of the zero tool 3; the workpiece fork 102 is used to drive the workpiece spindle 101 to rotate around the workpiece spindle 101 center in the angular limit groove 1031 of the workpiece fork support 103; and the left and right limit positions of the angular limit groove 1031 are used to form the rotation limit angle of the workpiece fork 102 of the actuator 1. That is, the limit angle detection of the actuator 1 with the above structure is applicable.

[0091] (As Figure 17 , Figure 18 )Insert the zero tool 3, and adjust the zero position of the actuator 1 through the zero tool 3, that is, step S2, zero position adjustment.

[0092] Specifically, step S2, zero position adjustment: insert the positioning end 301 of the zero tool 3 into the positioning groove 1011 of the workpiece spindle 101 of the actuator 1, and make the abutting end 302 of the zero tool 3 abut against the corresponding straight edge of the outer contour of the measured workpiece, that is, reset the workpiece fork 102 of the actuator 1 to the mechanical zero position of the actuator 1.

[0093] After the workpiece is zeroed, the control display 4 is read and zeroed, and the control display 4 is input to execute the standard value of the limit angle of the actuator 1; the zero tool 3 is removed, and the limit angle of the actuator 1 is detected, that is, step S3, adjusting the control display.

[0094] (Combined Figure 3 ) Specifically, step S3, adjusting the control display: press the zero switch 401 of the control display 4, and the display screen 402 of the control display 4 is read and zeroed; the standard value of the limit angle of the workpiece fork 102 of the actuator 1 to be detected is input to the control display 4 through the setting button 403.

[0095] (Combined Figure 24 , Figure 25 ) The output end of the actuator 1 is sequentially moved to the left and right limit positions, and the angle sensor 2-1 in the portable actuator output end limit angle detection device 2 is used to detect the limit angle detection value of the output end at the left and right limit positions of the actuator 1 in real time, and the limit angle detection value is displayed on the control display 4; at the same time, the control display 4 prompts whether the detected limit angle of the actuator 1 is qualified or not in the form of an alarm. That is, step S4, left limit position detection, and step S5, right limit position detection, described below.

[0096] Specifically, step S4, left limit position detection: manually move the workpiece fork 102 of the actuator 1 to the left limit position, read the value 1 feedback by the display screen 402 of the control display 4, and know whether the left limit position detection result of the actuator 1 is qualified or not through the alarm indicator light 405 on the control display 4.

[0097] Specifically, step S5, right limit position detection: manually move the workpiece fork 102 of the actuator 1 to the right limit position, read the value 2 feedback by the display screen 402 of the control display 4, and know whether the right limit position detection result of the actuator 1 is qualified or not through the alarm indicator light 405 on the control display 4.

[0098] Also included is a portable actuator output end limit angle detection device used in the portable actuator output end limit angle detection method.

[0099] (As Figure 4 , Figure 3 ) The portable actuator output end limit angle detection device 2 has a shell 2-2; the support frame 2-3 is concentrically installed in the shell 2-2.

[0100] Specifically, the support frame 2-3 has a mounting hole aligned with the shell 2-2, and then two M4 screws are used to concentrically constrain and fix the support frame 2-3 inside the shell 2-2.

[0101] The support frame 2-3 is connected with the angle sensor 2-1 at the bottom center. Specifically, the angle sensor 2-1 is fixed on the support frame 2-3 by three M3 screws.

[0102] The angle sensor 2-1 is connected with the bottom end of the coupling 2-4 at the top detection input end; the coupling 2-4 is connected with the bottom end of the detection mandrel 2-6 at the top; preferably, the coupling 2-4 is a coaxial sleeve structure.

[0103] The detection mandrel 2-6 is rotatably supported by a bearing at the center of the end cover 2-5; the bearing is arranged to make the detection mandrel 2-6 rotate flexibly and reliably without jamming.

[0104] The end cover 2-5 is connected with the top of the shell 2-2 in a coaxial manner to ensure the coaxiality of the detection mandrel; the top of the detection mandrel 2-6 extends out of the end cover 2-5; the top of the detection mandrel 2-6 extending out of the end cover 2-5 is connected with the bottom center counterbore 1012 of the workpiece mandrel 101 in a coaxial interference fit, and is rotationally limited by the workpiece fork 102 and the workpiece mandrel 101 in a coaxial manner, thereby ensuring the detection accuracy.

[0105] It can be seen that the portable execution mechanism output end limit angle detection device 2 has high coaxiality of each component, reliable detection, and convenient movement.

[0106] The end cover 2-5 is also provided with a quick pressure clamp 5; the quick pressure clamp 5 is used to press and fix the workpiece fork support 103 at the top of the device.

[0107] (Combined Figure 10 ) The portable execution mechanism output end limit angle detection device 2 is provided with a zero position tool 3. The zero position tool 3 has a positioning end 301 and a supporting end 302 perpendicular to each other.

[0108] The supporting end 302 has a vertical side wall abutting the left or right vertical outer side wall of the workpiece fork support 103 being clamped; the positioning end 301 is inserted into the left and right axis-symmetric positioning grooves 1011 of the workpiece mandrel 101 in an interference fit, and in the state that the zero position tool 3 is inserted into the positioning grooves 1011, the positioning grooves 1011 and the fork grooves 1021 of the workpiece fork 102 are perpendicular to each other, at this time, the zero position tool 3 resets the workpiece fork 102 of the execution mechanism 1 to the mechanical zero position.

[0109] In the above embodiment, further, the zero position tool 3 also has a handle I 303; the handle I 303 is perpendicular to the outer vertical side wall of the supporting end 302, and the handle I 303 is arranged outside the supporting end 302.

[0110] It can be seen that the zero tool 3 has simple structure, is convenient to use, and can calibrate and adjust the zero position of the actuator 1 by inserting, so that the mechanical zero position reset of the actuator 1 is simple, fast, reliable and efficient.

[0111] (Combined Figure 26 ) On this basis, in order to realize fast and intuitive display of the limit angle detection value of the actuator 1 and facilitate the staff to quickly know whether the detection result is qualified or not, the angle sensor 2-1 is electrically connected to the input end of the control display 4.

[0112] The control display 4 adopts a control display instrument of Model WF160J of Yantai Yifeng Sensor Measurement and Control Technology Company as a main body to realize detection after modification.

[0113] The control display 4 has a power switch 404, an alarm indicator 405, a zero setting switch 401, a setting button 403 and a display screen 402.

[0114] The alarm indicator 405 includes two, one is an alarm indicator for the left limit position, and the other is an alarm indicator for the right limit position.

[0115] The control display 4 has complete functions, has a limit angle standard value input function, a limit angle detection value data display function, a data zero setting function and a light alarm function, and meets the use requirement of efficiently and intuitively obtaining the detection result.

[0116] The working principle of the application is that after the portable actuator output end limit angle detection device 2 is righted and tightly fixed and clamped with the actuator 1, only the zero tool 3 needs to be simply inserted, the detection value of the control display 4 is adjusted to zero, the standard value is input, and then the workpiece yoke 102 is dithered to the left and right limit positions, so that the limit angle detection value can be quickly and intuitively obtained through the control display 4, and whether the detection result is qualified or not can be intuitively judged through the alarm indicator 405. 1; and the value fed back by the display when the workpiece output end is rotated counterclockwise to the right limit position is 2, so that the single direction limit angle of the actuator 1 is 1, 2, and the total limit angle of the workpiece is 0= 1+ 2; for example, the technical requirement of the application is =± (26°±0.5°). Meanwhile, the measurement result is intuitively displayed by the corresponding indicator light whether it is qualified or not. It can be seen that the detection efficiency is high, the detection result is accurate and reliable, the requirement for the technical personnel is low, and the limit angle of the actuator 1 is suitable for rapid, batch, efficient and accurate detection.

[0117] It can be found from the above description that, compared with the existing laser point calculation measurement, the present application has the following advantages: the measurement is not restricted by the measurement site, environmental temperature and other conditions, and the on-site measurement has obvious advantages; meanwhile, the present application has low operation difficulty, fast data obtaining, easy portability, simple overall use and assembly, low manufacturing cost, simple and fast operation, accurate and reliable reading, light weight, and the like. In addition, the unqualified direction and specific value of the limit angle of the measured workpiece can be reflected through the measurement data, which is convenient for finding the unqualified reason, guiding the assembly, ensuring the assembly quality and improving the production efficiency.

[0118] Furthermore, the device of the present application is not only suitable for the detection of the same type of servo transmission mechanism, but also can be used for the precision measurement of other mechanical similar products, and the use method and effect are equally remarkable. It is particularly suitable for products that are mass-produced, frequently detected, need to be adjusted in time, and cannot be intuitively measured by a measuring tool.

[0119] In summary, the present application has the same measurement principle as the existing measurement method, and the difference lies in that only the preparation work before the measurement is needed, that is, the angle sensor 2-1 and the control display 4 are checked within the accuracy requirement range to ensure the effectiveness of the evaluation analysis, and the on-site management of the measuring instrument is needed to carry out the calibration before use; the device is simple to operate, and can be operated according to the standard requirements without special training. Compared with the laser point calculation measurement, the requirement for the operator is greatly reduced, the production efficiency is significantly improved, and the production cost is saved.

[0120] Each embodiment in the specification is described in a related manner, and the same and similar parts between each embodiment can be referred to each other. Each embodiment mainly describes the difference from other embodiments.
