[0001] This utility model relates to the field of cycloidal wheel testing technology, and in particular to a rapid testing instrument for the tooth profile accuracy of cycloidal wheels. Background Technology

[0002] During the production of cycloidal gears, gear profile inspection is required. For example, existing patent publication number CN223021211U, entitled "A Gear Three-Dimensional Profile Measurement Device Based on Line Laser Scanning," proposes a device comprising: a base, a fixing mechanism, and a fixing plate. The fixing mechanism includes a fixed seat, a first motor, and an arc-shaped plate. The fixed seat is rotatably connected to the base. The interior of the fixed seat is hollow, and a guide groove is provided on the fixed seat, communicating with the interior of the fixed seat. The first motor is mounted on the bottom inner wall of the fixed seat, and a gear is fixedly connected to its output end. A limit groove is provided on the inner wall of the guide groove, and a limit block is provided on the outer wall of the arc-shaped plate. The arc-shaped plate is connected to the limit groove through the limit block. This invention provides good fixing for gears of different sizes during use and keeps the gear in the center position of the fixed seat, thus ensuring the accuracy of the measuring head's measurement of the gear.

[0003] However, the device disclosed in the above patent cannot quickly fix or disassemble the cycloidal wheel during use, which reduces the detection efficiency of the cycloidal wheel. Therefore, it is necessary to propose a rapid detection instrument for the tooth profile accuracy of the cycloidal wheel to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid testing instrument for the tooth profile accuracy of cycloidal gears, in order to solve the problem mentioned in the background art that the existing technology for testing the gear profile of cycloidal gears cannot quickly fix or disassemble the cycloidal gears, thus reducing the testing efficiency of the cycloidal gears.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid testing instrument for the profile accuracy of a cycloidal gear, comprising a testing platform, a rotating platform rotatably mounted on the top of the testing platform via a power assembly, two symmetrically distributed heightening columns fixedly mounted on the top of the rotating platform, a placement platform fixedly mounted between the upper ends of the two heightening columns, a clamping assembly mounted on the placement platform, and a testing assembly mounted on the top of the testing platform.

[0006] The clamping assembly includes a central groove located in the center of the placement platform. Three movable grooves are evenly arranged in a ring on the side of the central groove. The central groove and the movable grooves are interconnected. A movable block is slidably disposed inside the movable groove. Limit grooves are fixedly disposed on both sides of the movable groove. A limit rod is slidably disposed inside the limit groove. The limit rod is fixedly connected to the movable block. A spring is fixedly connected between the end of the movable groove and the movable block. A fixing block is fixedly disposed on the top of the movable block.

[0007] The top of the rotating platform is provided with a support assembly.

[0008] Preferably, the spreading component includes a threaded column, which is fixedly disposed in the middle of the top of the rotating platform. A threaded cylinder is threadedly connected to the outer ring of the threaded column, and a conical block is fixedly disposed at the upper end of the threaded cylinder. The conical block is located directly below the central groove, and a through hole is provided inside the conical block for the threaded column to move through.

[0009] Preferably, in the initial state, the three movable blocks are in contact with each other, and the end of the limiting rod away from the central groove is located inside the limiting groove.

[0010] Preferably, the side of the fixed block is provided with an arc surface, and the lower end of the movable block is provided with an inclined surface, the slope of which is consistent with the taper of the conical block.

[0011] Preferably, the power assembly includes a housing, which is fixedly installed at the bottom of the testing platform. A motor is installed inside the housing, and the output shaft of the motor passes through the upper surface of the testing platform and is fixedly connected to the rotating platform.

[0012] Preferably, side plates are fixedly installed at both ends of the bottom of the testing platform.

[0013] Preferably, the detection component includes a laser detector, the upper surface of the detection platform is provided with a sliding groove, a lead screw is rotatably arranged inside the sliding groove, a slider is threadedly connected to the outer ring of the lead screw, a telescopic rod is fixedly arranged on the top of the slider, and the laser detector is fixedly arranged at the telescopic end of the telescopic rod.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the process of using this utility model, the fixing and disassembly of the cycloidal wheel can be quickly completed by simply rotating the threaded cylinder in both directions. This solves the problem that the existing technology cannot quickly fix or disassemble the cycloidal wheel when performing gear profile testing, which reduces the testing efficiency of the cycloidal wheel.

[0016] 2. In the initial state of use, the three movable blocks are in contact with each other, and the end of the limiting rod away from the center groove is located inside the limiting groove. This facilitates the placement of the center hole of the cycloidal wheel over the outside of the three fixed blocks. The cycloidal wheel is then placed on the placement table. Rotating the threaded cylinder causes the conical block to move upward. Since the lower end of the movable block has an inclined surface with a slope that matches the taper of the conical block, after the conical block moves upward and touches the inclined surface, it pushes the three movable blocks to move synchronously as the conical block continues to move upward. This, in turn, causes the three fixed blocks to move synchronously. The three fixed blocks are pressed against the inner wall of the center hole of the cycloidal wheel, quickly fixing the cycloidal wheel and ensuring that it is in the center position, thereby ensuring the accuracy of the cycloidal wheel measurement.

[0017] 3. After fixing the cycloidal wheel, start the motor to drive the rotating table to rotate, which in turn drives the cycloidal wheel to rotate. The laser detector will inspect its tooth profile. When the size of the cycloidal wheel is different, rotate the lead screw to drive the slider, telescopic rod and laser detector to move horizontally, and drive the laser detector to move vertically through the telescopic rod, thereby accommodating cycloidal wheels of different sizes and improving the applicability of the device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The cycloidal gear tooth profile accuracy rapid testing instrument shown includes a testing platform 1. A rotating platform 4 is rotatably mounted on the top of the testing platform 1 via a power component. Two symmetrically distributed heightening columns 5 are fixedly mounted on the top of the rotating platform 4. A placement platform 6 is fixedly mounted between the upper ends of the two heightening columns 5. A clamping component is mounted on the placement platform 6. A testing component is mounted on the top of the testing platform 1.

[0026] The clamping assembly includes a central groove 7, which is located in the center of the placement platform 6. Three movable grooves 8 are evenly arranged in a ring on the side of the central groove 7. The central groove 7 and the movable grooves 8 are interconnected. A movable block 11 is slidably disposed inside the movable groove 8. Limiting grooves 9 are fixedly disposed on both sides of the movable groove 8. A limiting rod 10 is slidably disposed inside the limiting groove 9. The limiting rod 10 is fixedly connected to the movable block 11. A spring 13 is fixedly connected between the end of the movable groove 8 and the movable block 11. A fixing block 12 is fixedly disposed on the top of the movable block 11.

[0027] The top of the rotating platform 4 is provided with a support assembly, which includes a threaded post 14. The threaded post 14 is fixedly installed in the middle of the top of the rotating platform 4. The outer ring of the threaded post 14 is threadedly connected to a threaded cylinder 15. A conical block 16 is fixedly installed at the upper end of the threaded cylinder 15. The conical block 16 is located directly below the central groove 7. A through hole is opened inside the conical block 16 for the threaded post 14 to move through.

[0028] Specifically, in the initial state of use, the three movable blocks 11 are in contact with each other, and the end of the limiting rod 10 away from the central groove 7 is located inside the limiting groove 9. This facilitates the placement of the central hole of the cycloidal wheel onto the outside of the three fixed blocks 12, and the cycloidal wheel is placed on the placement platform 6. Rotating the threaded cylinder 15 causes the conical block 16 to move upward. Since the lower end of the movable block 11 is provided with an inclined surface, the slope of which is consistent with the taper of the conical block 16, after the conical block 16 moves upward and touches the inclined surface, as the conical block 16 continues to move upward, it pushes the three movable blocks 11 to move synchronously, thereby causing the three fixed blocks 12 to move synchronously. The three fixed blocks 12 are pressed against the inner wall of the central hole of the cycloidal wheel, quickly fixing the cycloidal wheel and ensuring that it is in the center position, thereby ensuring the accuracy of the cycloidal wheel measurement.

[0029] When it is necessary to disassemble the cycloidal wheel, rotate the threaded cylinder 15 in the opposite direction to drive the conical block 16 to move downward. At this time, the spring 13 restores its elasticity, pushes the movable block 11 to move and reset, and then causes the fixed block 12 to move and loosen the cycloidal wheel, so that the cycloidal wheel can be quickly disassembled.

[0030] The stability of the displacement of the movable block 11 is ensured by setting the limiting groove 9 and the limiting rod 10.

[0031] In summary, this utility model allows for quick fixing and disassembly of the cycloidal wheel simply by rotating the threaded cylinder 15 in both directions during use. This solves the problem in existing technologies where the cycloidal wheel cannot be quickly fixed or disassembled when performing gear profile testing, thus reducing the testing efficiency of the cycloidal wheel.

[0032] Furthermore, the side of the fixing block 12 is provided with an arc surface, which makes the fixing block 12 fit better against the inner wall of the center hole of the cycloidal wheel.

[0033] Furthermore, the power assembly includes a housing 3, which is fixedly installed at the bottom of the testing table 1. A motor is installed inside the housing 3, and the output shaft of the motor passes through the upper surface of the testing table 1 and is fixedly connected to the rotating table 4. Side plates 2 are fixedly installed at both ends of the bottom of the testing table 1.

[0034] Furthermore, the detection assembly includes a laser detector 19, a groove is provided on the upper surface of the detection table 1, a lead screw 17 is rotatably arranged inside the groove, a slider is threadedly connected to the outer ring of the lead screw 17, a telescopic rod 18 is fixedly arranged on the top of the slider, and the laser detector 19 is fixedly arranged at the telescopic end of the telescopic rod 18.

[0035] After fixing the cycloidal wheel, start the motor to drive the rotating table 4 to rotate, which in turn drives the cycloidal wheel to rotate. The laser detector 19 detects its tooth profile. When the size of the cycloidal wheel is different, rotate the lead screw 17 to drive the slider, telescopic rod 18 and laser detector 19 to move horizontally, and drive the laser detector 19 to move vertically through the telescopic rod 18, thereby accommodating cycloidal wheels of different sizes and improving the applicability of the device.

[0036] Working Principle: In the initial state of use, the three movable blocks 11 are in contact with each other, and the end of the limiting rod 10 away from the central groove 7 is located inside the limiting groove 9. This facilitates the placement of the central hole of the cycloidal wheel onto the outside of the three fixed blocks 12. The cycloidal wheel is then placed on the placement platform 6. Rotating the threaded cylinder 15 causes the conical block 16 to move upward. Since the lower end of the movable block 11 has an inclined surface with a slope that matches the taper of the conical block 16, after the conical block 16 moves upward and touches the inclined surface, it pushes the three movable blocks 11 to move synchronously, thereby causing the three fixed blocks 12 to move synchronously. The three fixed blocks 12 are pressed tightly against the inner wall of the central hole of the cycloidal wheel, quickly oscillating the cycloidal wheel. The cycloidal wheel is fixed in place and centered to ensure the accuracy of the measurement. After fixing the cycloidal wheel, the motor is started, which drives the rotating table 4 to rotate, thereby driving the cycloidal wheel to rotate. The laser detector 19 detects its tooth profile. When the size of the cycloidal wheel is different, the lead screw 17 is rotated, which drives the slider, telescopic rod 18 and laser detector 19 to move horizontally. The telescopic rod 18 drives the laser detector 19 to move vertically, thus accommodating cycloidal wheels of different sizes. After the detection is completed, the threaded cylinder 15 is rotated in the opposite direction, which drives the conical block 16 to move downward. At this time, the spring 13 restores its elasticity, pushes the movable block 11 to move and reset, and then causes the fixed block 12 to move and release the cycloidal wheel, so that the cycloidal wheel can be quickly disassembled.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
