Description

Technical Field

[0001] The utility model relates to the technical field of gear detection, and specifically relates to a gear thickness detection device. Background Art

[0002] A gear is a mechanical component that is widely used in various mechanical devices for transmitting power and changing the rotational speed, torque, or rotational direction. During the gear production process, tooth thickness detection is one of the important steps to ensure product quality.

[0003] Since most gears are circular and several teeth on their periphery are distributed in a circular pattern around the center of the gear, it is often difficult to accurately determine the positions between the tooth root and the tooth top at one time when detecting the tooth thickness of the gear (tooth thickness refers to the thickness between the tooth root and the tooth top of the gear). As a result, the detection efficiency is low, and the detection accuracy may also be low. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a gear thickness detection device to solve the problem that it is difficult to accurately determine the positions between the tooth root and the tooth top at one time when detecting the tooth thickness of the gear, resulting in low detection efficiency and possibly low detection accuracy.

[0005] To achieve the above object, the utility model provides the following technical solution: A gear thickness detection device includes a bottom plate. A L-shaped plate and a support plate are fixedly connected to the upper surface of the bottom plate. The other end of the L-shaped plate is connected to a detection mechanism. The upper end of the support plate is connected to a rotation mechanism. One end of the rotation mechanism close to the L-shaped plate is connected to a moving mechanism. The other end of the moving mechanism is connected to two clamping assemblies. The other ends of the two clamping assemblies are both connected to clamping rods. The two clamping rods are parallel to each other vertically, and the detection mechanism is perpendicular to both clamping rods.

[0006] Further, the rotation mechanism includes a rotation motor and a rotation box. The outer wall of the rotation motor is fixedly connected to the side wall of the support plate. The output shaft of the rotation motor penetrates through the support plate and is fixedly connected to the outer wall of the rotation box. The other end of the rotation box is connected to the moving mechanism.

[0007] Further, a moving port is provided on one side of the rotation box away from the rotation motor. One ends of the moving mechanism and the two clamping assemblies are both located in the moving port.

[0008] Further, the moving mechanism includes a moving motor and a bidirectional lead screw. The outer wall of the moving motor is fixedly connected to one end of the rotation box. The output shaft of the moving motor is fixedly connected to one end of the bidirectional lead screw. The other end of the bidirectional lead screw penetrates through the rotation box and the two clamping assemblies and is rotatably connected to the inner wall of the moving port.

[0009] Further, the clamping assembly includes a threaded block and an extension plate. The threaded block is sleeved and threadedly connected to the outer wall of the bidirectional lead screw. The outer wall of the threaded block is slidably connected to the inner wall of the moving port. One side of the threaded block is fixedly connected to one side of the extension plate. The other end of the extension plate is connected to one end of the clamping rod.

[0010] Further, a threaded hole is formed in one side of the extension plate away from the threaded block. One end of the clamping rod is located in the threaded hole, and the outer wall of this end of the clamping rod is threadedly connected to the inner wall of the threaded hole.

[0011] Further, the detection mechanism includes an electric push rod and a detection head. The outer wall of the electric push rod is fixedly connected to the upper surface of the L-shaped plate. The output end of the electric push rod penetrates through the L-shaped plate and is fixedly connected to the upper end of the detection head. Both the electric push rod and the detection head are perpendicularly arranged to the clamping rod.

[0012] Further, a top plate is fixedly connected to the upper surface of the bottom plate. The top plate is located on the side of the detection mechanism and the clamping rod close to the L-shaped plate.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] For this kind of gear thickness detection device, by setting an L-shaped plate and a support plate on the bottom plate, setting a detection mechanism on the L-shaped plate, and setting a rotation mechanism, a moving mechanism, two clamping assemblies and two clamping rods on the support plate. When it is necessary to detect the tooth thickness of the gear, only need to control the clamping assembly to move through the moving mechanism, and then the gear can be clamped from both sides by the two clamping rods. Subsequently, the height of the tooth root is detected by the detection mechanism. After the gear is rotated by a certain angle through the rotation mechanism, the height of the tooth tip is detected by the detection mechanism again. Finally, the height difference between the tooth root and the tooth tip is obtained, and the tooth thickness can be directly obtained, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Please refer to Figures 1 - 5 , a gear thickness detection device, including a bottom plate 1, an L-shaped plate 2 and a support plate 5 are fixedly connected to the upper surface of the bottom plate 1, the other end of the L-shaped plate 2 is connected with a detection mechanism, the upper end of the support plate 5 is connected with a rotating mechanism, one end of the rotating mechanism close to the L-shaped plate 2 is connected with a moving mechanism, the other end of the moving mechanism is connected with two clamping assemblies, the other ends of the two clamping assemblies are both connected with clamping rods 10, the two clamping rods 10 are parallel up and down, and the detection mechanism and the two clamping rods 10 are both vertically arranged.

[0023] As Figures 1 to 5 shown, when the gear thickness detection device in the present invention is in use, first place one tooth root of the gear to be detected on the lower clamping rod 10, and then start the moving mechanism. The moving mechanism can drive the two clamping assemblies to move towards the middle at the same time. During the moving process, the upper clamping rod 10 will clamp the gear in the center from the corresponding tooth root above the gear. Then turn on the detection mechanism, and the detection mechanism descends and will abut against the tooth root at the top of the gear. At this time, the detection mechanism will directly record the corresponding data. Then the detection mechanism rises. At this time, the rotating mechanism starts to rotate the gear by an angle so that the tooth top faces up. Then start the detection mechanism again. After the detection mechanism descends again, the distance between the detection mechanism and the tooth top is detected. Then subtract the tooth top distance from the tooth root distance to obtain the distance (i.e., thickness) between the tooth root and the tooth top, which is convenient and fast.

[0024] It should be particularly noted here that:

[0025] Taking the gear in the figure as an example here, the gear has 24 teeth, and the angle between two adjacent tooth roots is 360 / 24 = 15 degrees. At this time, only need to control the rotating mechanism to rotate 15 / 2 = 7.5 degrees in advance through the PLC controller to rotate the tooth top position of the gear upwards. Of course, this is only an example for illustration. The angles of actual different gears are different, and all are subject to the actual situation. No specific limitation is made here.

[0026] If you are worried that the one-time detection data is inaccurate, you can restart the rotating mechanism. After rotating a specific angle, repeat the above steps to detect the distance between other tooth roots and tooth tips.

[0027] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the rotating mechanism includes a rotating motor 6 and a rotating box 7. The outer wall of the rotating motor 6 is fixedly connected to the side wall of the support plate 5. The output shaft of the rotating motor 6 passes through the support plate 5 and is fixedly connected to the outer wall of the rotating box 7. The other end of the rotating box 7 is connected to the moving mechanism.

[0028] More specifically, when it is necessary to control the rotation of the moving mechanism, just turn on the rotating motor 6. After the rotating motor 6 starts, the output shaft can drive the rotating box 7 to rotate. After the rotating box 7 rotates, it can drive the moving mechanism located at the other end of the rotating box 7 to rotate.

[0029] As Figure 2 , Figure 4 and Figure 5 shown, a moving port 701 is provided on the side of the rotating box 7 away from the rotating motor 6. One end of the moving mechanism and two clamping components are both located in the moving port 701.

[0030] More specifically, by providing the moving port 701, a support and accommodation can be given to the moving mechanism and the clamping components, and the moving direction and trajectory of the moving mechanism and the clamping components can be limited.

[0031] As Figure 2 , Figure 4 and Figure 5 shown, the moving mechanism includes a moving motor 8 and a bidirectional lead screw 11. The outer wall of the moving motor 8 is fixedly connected to one end of the rotating box 7. The output shaft of the moving motor 8 is fixedly connected to one end of the bidirectional lead screw 11. The other end of the bidirectional lead screw 11 passes through the rotating box 7 and two clamping components and is rotatably connected to the inner wall of the moving port 701.

[0032] More specifically, when it is necessary to control the movement of the clamping mechanism, just turn on the moving motor 8. After the moving motor 8 starts, the output shaft can control the bidirectional lead screw 11 to rotate. After the bidirectional lead screw 11 rotates, it can drive the two clamping components connected to its surface to move.

[0033] As Figure 2 , Figure 4 and Figure 5As shown, the clamping assembly includes a threaded block 12 and an extension plate 9. The threaded block 12 is sleeved and threadedly connected to the outer wall of the bidirectional lead screw 11. The outer wall of the threaded block 12 is slidably connected to the inner wall of the moving port 701. One side of the threaded block 12 is fixedly connected to one side of the extension plate 9. The other end of the extension plate 9 is connected to one end of the clamping rod 10.

[0034] More specifically, when the bidirectional lead screw 11 rotates, the threaded block 12 will be forced to move up and down along the bidirectional lead screw 11 under the restriction of the moving port 701, thereby driving the extension plate 9 to move up and down together, so as to clamp the intermediate gear.

[0035] As Figure 5 shown, a threaded hole 901 is provided on the side of the extension plate 9 away from the threaded block 12. One end of the clamping rod 10 is located in the threaded hole 901, and the outer wall of this end of the clamping rod 10 is threadedly connected to the inner wall of the threaded hole 901.

[0036] More specifically, since the overall widths of different gears are also different, at this time, the clamping rod 10 can be rotated to move back and forth in the threaded hole 901, so as to change the extended length of the clamping rod 10 to adapt to more different gears.

[0037] As Figures 1 - 3 shown, the detection mechanism includes an electric push rod 3 and a detection head 13. The outer wall of the electric push rod 3 is fixedly connected to the upper surface of the L-shaped plate 2. The output end of the electric push rod 3 penetrates through the L-shaped plate 2 and is fixedly connected to the upper end of the detection head 13. Both the electric push rod 3 and the detection head 13 are perpendicular to the clamping rod 10.

[0038] More specifically, when it is necessary to detect the distance between the tooth root and the tooth top of the gear, only need to start the electric push rod 3. After the electric push rod 3 starts, the output end extends outwards, and then it can drive the detection head 13 to descend together. During the descent of the detection head 13, after it abuts against the tooth root and the tooth top of the gear, the descent height can be automatically measured, and finally the difference between the two can be obtained to get the final result.

[0039] As Figures 1 - 3 shown, a top plate 4 is fixedly connected to the upper surface of the bottom plate 1. The top plate 4 is located on the side of the detection mechanism and the clamping rod 10 close to the L-shaped plate 2.

[0040] More specifically, by setting the top plate 4, when installing the gear, only need to press one side of the gear against the top plate 4, and then clamp it with the clamping rod 10. This not only facilitates installation, but also can prevent the gear from being extruded and slipping from one side under the clamping of the two clamping rods 10.

[0041] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
