Description

Technical Field

[0001] This utility model relates to the field of detection devices, specifically a gear tooth profile detection device. Background Technology

[0002] As a core component in mechanical transmission, the tooth profile and direction accuracy of gears directly affect transmission efficiency, noise, and lifespan. Tooth profile and direction measuring instruments are typically used to inspect the tooth profile and direction of gears, specifically to detect deviations in the gear tooth profile and helix.

[0003] The tooth profile and tooth direction measuring instrument includes a high-precision transmission device to ensure stable gear rotation; a precise measurement system, such as a probe and laser sensor; a control system, such as a PLC to control the measurement path and achieve automated scanning; and a data processing system that can collect data in real time via computer to generate error curves and reports. Its measurement principle is mainly based on the meshing of the base disk and the gear to simulate the involute generation process and directly measure the tooth profile error. Alternatively, it can measure the coordinates of multiple points on the tooth surface through high-precision sensors and compare them with theoretical values ​​to calculate the error.

[0004] Existing tooth profile and tooth direction measuring instruments typically use multiple bolts to fix the measuring part. However, during use and observation, it has been found that this fixing method is cumbersome and makes it difficult to quickly center the position of the measuring part.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the figure, a gear tooth profile detection device according to an embodiment of the present invention includes a housing 1. A first slide rail 12 is slidably connected to the top of the housing 1. A support seat 13 is slidably fitted on the outer wall of the first slide rail 12. A probe 14 is fixedly installed in the middle of the support seat 13. A second slide rail 15 is fixedly installed on the top of the housing 1. A pressure plate 16 is slidably fitted on the outer wall of the second slide rail 15. A computer 17 is installed on the top of the housing 1. The probe 14 and the computer 17 are connected by a signal. A fixing plate 120 is fixedly connected to the bottom of the housing 1. A motor 18 is fixedly connected to the bottom of the housing 1. A first gear 19 is fixedly connected to the output end of the motor 18, and the first gear 19 and the fixing plate 120 are rotatably connected. A second gear 110 is rotatably connected to the top of the fixing plate 120. The second gear 110 and the first gear 19 are meshed; a cylinder 111 is fixedly connected to the top of the second gear 110; a disc 113 is rotatably connected to the top of the housing 1; a sliding groove 112 is fixedly connected to the bottom of the disc 113; the sliding groove 112 and the cylinder 111 are both fixedly connected; a plurality of first sliders 114 are slidably fitted on the inner wall of the disc 113, and a spring telescopic rod 115 is fixedly connected between the first sliders 114 and the inner wall of the disc 113; a clamping block 118 is provided on the top of the first sliders 114; a measuring element 119 is provided between the plurality of clamping blocks 118; a second slider 116 is fixedly connected to the output end of the cylinder 111, and the second slider 116 and the sliding groove 112 are slidably connected; a pull rope 117 is fixedly connected between the second slider 116 and the plurality of first sliders 114.The measuring piece 119 is placed on top of the disc 113, and the second slider 116 is moved by the starting cylinder 111. The second slider 116 slides along the slide groove 112 and pulls the first slider 114 by the pull rope 117. The first slider 114, along with the clamping block 118, moves closer to the measuring piece 119 at the center of the disc 113 until the clamping block 118 can press and fix the measuring piece 119. During this process, the spring telescopic rod 115 is in a stretched state. Then, the pressure plate 16 is driven to move vertically along the second slide rail 15 by the control module until its bottom rotating part abuts against the measuring piece 119. At this time, the device achieves centering and fixing of the measuring piece 119. Then, the first slide rail 12 is controlled to slide along the housing 1 by the control module so that the support base 13 and the probe 14 move closer to the measuring piece 119. When the probe 14 is close to the area to be measured on the measuring piece 119, the motor 18 can be started.

The control of the relevant components of the second slide rail 15 and the first slide rail 12 is electrically controlled, and the principle of the probe 14 scanning and measuring the measuring piece 119 is a publicly disclosed technique in this field, so it will not be elaborated here. Through the cooperation of the second slider 116 and the first slider 114, the first slider 114 can quickly clamp the measuring piece 119 with the clamping block 118, simplifying the operation required to fix the measuring piece 119 and improving the accuracy of the device's position when fixing the measuring piece 119.

When the pull rope 117 moves, it can move along the fixed pulleys 2 and make the fixed pulleys 2 rotate under friction, so as to reduce the direct contact between the pull rope 117 and the inner wall of the pull rope 117 when the pull rope 117 moves, and reduce the friction and wear of the pull rope 117 when it moves; by setting the fixed pulleys 2, the fixed pulleys 2 can reduce the direct contact between the pull rope 117 and other components, reduce the wear of the pull rope 117 when it moves, and extend the service life of the pull rope 117.

[0027] Please see Figure 4As shown, the first slider 114 has a threaded part 3 fixedly connected to its top; the clamping block 118 and the threaded part 3 are threadedly connected; the outer wall of the clamping block 118 has a positioning groove 32; when it is necessary to clamp measuring parts 119 of different sizes, the clamping block 118 can be rotated to disengage it from the threaded part 3, and the positioning groove 32 at the clamping block 118 with different curvatures can be aligned with the through groove on the disc 113. After rotating several times, the clamping block 118 can be tightened. Then, the parallelism between the positioning groove 32 and the through groove can be used to judge the accuracy of the installation of the new clamping block 118, so that the device can accurately replace the clamping block 118 and adapt to the clamping work of measuring parts 119 of different sizes.

[0028] Please see Figure 3 and Figure 4 As shown, silicone 4 is fixed to the inner wall of the clamping block 118; the outer wall of the silicone 4 has an arc-shaped structure; by setting silicone 4, when the clamping block 118 clamps the measuring piece 119, silicone 4 can contact the measuring piece 119 before the clamping block 118. Silicone 4 is a flexible material, which can disperse the squeezing effect on the surface of the measuring piece 119, so as to reduce the damage to the surface of the measuring piece 119 caused by excessive squeezing.

[0029] Please see Figure 1 As shown, the top of the housing 1 is provided with a support frame 5; the surface of the support frame 5 is provided with multiple arc-shaped grooves; by setting the support frame 5, a support frame 5 with an arc-shaped groove of a corresponding size can be selected according to the different sizes of the test piece 119 to be tested for pre-storage, which is convenient for the subsequent retrieval of the test piece 119. At the same time, the position of the support frame 5 can be arbitrarily placed according to the actual operation.

[0030] Please see Figure 5 As shown, a pair of adjusting seats 62 are fixedly connected to the top of the disc 113; multiple mounting holes are provided on the surface of the adjusting seats 62; a mounting base is provided between the adjusting seats 62, and an air tube 6 is fixedly installed on the mounting base; before the probe 14 scans the test area of ​​the test piece 119, a clean airflow can be generated by connecting the air tube 6 to an external air pump. The airflow can perform air jet cleaning on the surface of the test piece 119, reducing the dust and impurities attached to the surface of the test piece 119. At the same time, the cleaning angle of the air tube 6 can be adjusted by selecting different mounting holes and fixing the mounting base with pins.

[0031] Working principle: The measuring piece 119 is placed on top of the disc 113, and the second slider 116 is moved by the starting cylinder 111. The second slider 116 slides along the slide groove 112 and pulls the first slider 114 by the pull rope 117. The first slider 114, along with the clamping block 118, moves closer to the measuring piece 119 at the center of the disc 113 until the clamping block 118 can press and fix the measuring piece 119. During this process, the spring telescopic rod 115 is in a stretched state. Then, the pressure plate 16 is driven to move vertically along the second slide rail 15 by the control module until its bottom rotating part abuts against the measuring piece 119. At this time, the device achieves centering and fixing of the measuring piece 119. Then, it can be... The control module controls the first slide rail 12 to slide along the housing 1, so that the support base 13 and the probe 14 move closer to the measuring piece 119. When the probe 14 is close to the area to be measured on the measuring piece 119, the motor 18 can be started to drive the first gear 19 and the second gear 110 to mesh, so that the cylinder 111 drives the measuring piece 119 on the top of the disk 113 to rotate through the limiting action between the slide groove 112 and the second slider 116. At the same time, the support base 13 will move the probe 14 vertically along the first slide rail 12, so that the probe 14 can scan along the tooth profile of the area to be measured on the measuring piece 119 and record the data to be fed back to the computer 17. The control of the relevant components of the second slide rail 15 and the first slide rail 12 can be electrically controlled. The control mechanism, and the principle of probe 14 scanning and measuring the test piece 119, are already publicly known techniques in this field, so they will not be elaborated here. By setting a fixed pulley 2, the cylinder 111 controls the second slider 116 to move vertically, which can pull the pull rope 117. When the pull rope 117 moves, it can move along the fixed pulley 2, causing the fixed pulley 2 to rotate under friction, thereby reducing direct contact between the pull rope 117 and its inner wall, and reducing frictional wear. By setting the fixed pulley 2, the direct contact between the pull rope 117 and other components can be reduced, reducing wear during the movement of the pull rope 117 and extending its service life. Different sizes of test pieces 119 need to be measured... During clamping, the clamping block 118 can be rotated to disengage it from the threaded part 3, and the positioning groove 32 at the clamping block 118 with different curvatures can be aligned with the through groove on the disc 113. After rotating several times, the clamping block 118 can be tightened. Then, the parallelism between the positioning groove 32 and the through groove can be used to judge the accuracy of the installation of the new clamping block 118, so as to realize the accurate replacement of the clamping block 118 by the device, and make the device adaptable to the clamping work of measuring parts 119 of different sizes. By setting silicone 4, when the clamping block 118 clamps the measuring part 119, the silicone 4 can contact the measuring part 119 before the clamping block 118. The silicone 4 is a flexible material, which can disperse the squeezing force on the surface of the measuring part 119, so as to reduce the damage to the surface of the measuring part 119 caused by excessive squeezing.By setting up the support frame 5, a support frame 5 with a corresponding arc-shaped groove can be selected according to the different sizes of the test piece 119 to be tested for pre-storage, facilitating subsequent retrieval of the test piece 119. The position of the support frame 5 can be arbitrarily placed according to actual operation. Before the probe 14 scans the test area of ​​the test piece 119, an external air pump can be connected to the air tube 6 to generate a clean airflow. The airflow can perform air jet cleaning on the surface of the test piece 119, reducing dust and impurities adhering to the surface. Simultaneously, the cleaning angle of the air tube 6 can be adjusted by selecting different mounting holes and fixing the mounting base with pins.
