Description

Technical Field

[0001] The present invention relates to the field of planetary gear detection, and in particular to a planetary gear detection device and a detection method thereof. Background Art

[0002] A planetary gear refers to a gear system that, in addition to being able to rotate around its own axis like a fixed-axis gear, its axis of rotation also rotates around the axis of other gears along with the planet carrier. The rotation around its own axis is called "self-rotation", and the rotation around the axis of other gears is called "revolution", just like the planets in the solar system, hence the name. When producing planetary gears, it is necessary to detect each gear disk to check whether there are defects or missing teeth on the surface, and to detect the spacing between the teeth to determine whether the gear disks of the planetary gear are qualified. Most of the current detection methods use visual detection or meshing detection with a standard gear. However, during detection, only one item can be detected each time, such as appearance, size or teeth, which is not convenient for batch and rapid detection. Moreover, when detecting, for different types of gear disks, the number of teeth and the spacing between the teeth are different, resulting in poor applicability and inconvenience in use. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art and solve at least one problem proposed in the background art, a planetary gear detection device and a detection method thereof are proposed.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a planetary gear detection device, including a placement component for placing the gear disk to be detected, and a drive component for rotating and driving the gear disk to be detected is fixedly installed at the middle position of the placement component. A replaceable axis component is threadedly connected to the upper end axis position of the drive component. A tooth detection component for detecting the teeth of the detection gear disk is fixedly installed on one side of the placement component, and auxiliary detection components for detecting the surface of the detection gear disk are circumferentially arrayed and snap-connected on the upper surface of the placement component. When in use, the gear disk to be detected is sleeved on the axis component, and the drive component is used to rotate and drive the gear disk to be detected, so that the gear disk to be detected presses the auxiliary detection components. The auxiliary detection components detect the surface of the gear disk to check whether there are concave positions, and the tooth detection component detects the teeth of the gear disk to check whether there are problems such as missing teeth, tooth spacing, and tooth groove depth.

[0005] Preferably, the placement component includes a detection table. A through hole is formed in the middle position of the detection table, and the driving component is fixedly installed at the position of the through hole. The driving end of the driving component penetrates through the through hole and extends above the detection table. Bar-shaped grooves are formed in a circumferential array on the detection table, and pin holes are formed at both ends inside the bar-shaped grooves. The auxiliary detection component is clamped inside the bar-shaped grooves, and the lower end of the auxiliary detection component is clamped inside the pin holes. Through the bar-shaped grooves and the pin holes, it is convenient to replace different types of the auxiliary detection components according to different detection precisions, and the electrical components in the auxiliary detection component are electrically connected to an external control system.

[0006] Preferably, the driving component includes a mounting frame. The mounting frame is fixedly installed at the middle position of the lower surface of the placement component. A servo motor is fixedly installed at the middle position of the upper surface of the mounting frame. The output end of the servo motor is fixedly installed with a turntable, and a threaded groove is formed in the middle position of the upper surface of the turntable. The lower end of the axis component is threadedly connected inside the threaded groove. An electromagnet is inlaid on the upper surface of the turntable outside the threaded groove, and an anti-slip ring is fixedly installed on the upper surface of the turntable outside the electromagnet. Through the threaded groove, it is convenient to replace the axis components with different diameters according to different types of gear discs, so that the axis position of the gear disc to be measured is coaxial with the output shaft of the servo motor, with strong applicability. And through the turntable, it is convenient to drive the gear disc to rotate. Through the electromagnet, it is convenient to adsorb and fix the gear disc. The electromagnet is electrically connected to an external control system through an external conductive slip ring, and through the anti-slip ring, it is avoided that the gear disc generates displacement on the turntable when rotating and driving the gear disc, improving the detection precision.

[0007] Preferably, the axis component includes a shaft rod. A threaded rod is fixedly installed at the lower end of the shaft rod, and the threaded rod is threadedly connected to the driving component. The upper end of the shaft rod is of a frustum-shaped structure, and the diameter of the lower end of the shaft rod is matched with the shaft hole of the gear disc to be detected. Through the threaded rod, it is convenient to install the shaft rod and convenient to replace shaft rods with different thicknesses.

[0008] Preferably, the tooth detection component includes a mounting plate which is fixedly installed on one side of the placing component. And an electric telescopic rod is fixedly installed on the upper surface of the mounting plate. The telescopic end of the electric telescopic rod is fixedly installed with a movable block. T-shaped slide rods are fixedly installed on both sides of the movable block. Adjusting blocks are slidably clamped on the slide rods. Lead screws are rotatably installed at the lower ends of the slide rods on both sides of the movable block. The lead screws are threadedly connected to the adjusting blocks. Through the lead screws, it is convenient to adjust the distance between the movable block and the adjusting blocks, and thus it is convenient to detect different teeth and tooth grooves, improving the applicability when detecting different specifications of gear disks. And the displacement of the movable block is controlled by the electric telescopic rod, which is convenient to move the movable block and the adjusting blocks towards the teeth to detect the tooth positions. And when it contracts, it avoids affecting the rotation of the gear disk, and each gear tooth is detected one by one, improving the detection accuracy.

[0009] Preferably, a square-shaped slide hole is formed in the middle position of the adjusting block. The slide rod fits with the slide hole, and the slide rod is inserted into the interior of the slide hole. A threaded hole is formed at the lower end of the slide hole on the adjusting block. The lead screw is threadedly connected to the threaded hole. Sleeve tubes are fixedly installed at the upper ends of the movable block and the adjusting blocks, and a limit nut is threadedly connected to the upper end of the sleeve tube. An adjusting rod is inserted into the interior of the sleeve tube. One end of the limit nut presses against the adjusting rod. One end of the adjusting rod is fixedly installed with a vertical plate, and press-type detection sensors are uniformly fixedly installed on the vertical plate. Through the limit nut, it is convenient to adjust the extending length of the adjusting rod, so as to adjust the V-shaped angle and size formed by the press-type detection sensors on the movable block and the adjusting blocks, which is applicable to the detection of different specifications of teeth. And during detection, the press-type detection sensor on the movable block abuts against the end of the tooth on the gear disk, and the press-type detection sensor on the adjusting block abuts against the bottom of the tooth groove position on the gear disk. When the press triggers to form a V shape, it is determined that the tooth is complete. When the press does not trigger to form a V shape, such as when the press-type detection sensor at the tooth groove position is triggered while the press-type detection sensor at the tooth end position is not triggered, it is determined that there is an abnormality in the tooth, which is convenient for detection use.

[0010] Preferably, an L-shaped connecting frame is fixedly installed at the upper end of the movable block, and a ccd camera is fixedly installed at one end of the connecting frame. Through the ccd camera, it is convenient to collect visual images of the detected tooth positions.

[0011] Preferably, the auxiliary detection component includes an auxiliary strip, and pin rods are fixedly installed on both sides of the lower end of the auxiliary strip. The auxiliary strip is clamped inside the strip-shaped groove, and the pin rods are inserted into the pin holes. Cavities are arranged in an array inside the auxiliary strip. An auxiliary pressing sensor is fixedly installed at the lower end inside the cavity. Both the pressing detection sensor and the auxiliary pressing sensor adopt micro pressure sensors. A lifting seat is slidably clamped inside the cavity. A spring is fixedly installed at the lower end of the lifting seat, and the auxiliary pressing sensor is located inside the spring. The upper end of the auxiliary pressing sensor is in contact with the lower end of the lifting seat. A ball is rotatably installed at the upper end of the lifting seat, and the upper end of the ball protrudes from the upper surface of the detection table. When the detection gear disk rotates, the detection gear disk presses the ball, thereby compressing the spring. The lifting seat presses the auxiliary pressing sensor. When there is a defect on the surface of the gear disk, due to the stretching of the spring, the pressing on the auxiliary pressing sensor is released, thereby determining that there is a depression on the surface of the gear disk, which is convenient for surface detection.

[0012] A detection method for a planetary gear. According to the above planetary gear detection device, when performing detection, the method is as follows:

[0013] Step 1: According to different types of gear disks to be measured, select axle center components with different diameters and install the axle center components on the driving component;

[0014] Step 2: According to different surface detection requirements, install auxiliary detection components with different spacings on the placement component;

[0015] Step 3: Adjust the distance between the movable block and the adjusting block in the tooth detection component for the tooth pitch of the gear disk to be measured, and adjust the extended length of the adjusting rod so that a V-shaped structure is formed between the movable block and the pressing detection sensors on the adjusting block;

[0016] Step 4: Install the gear disk to be measured on the axle center component and magnetically adsorb and connect it to the driving component;

[0017] Step 5: The driving component drives the gear disk to be measured to rotate, and the surface of the gear to be measured is detected through the auxiliary pressing sensor in the auxiliary detection component to determine whether there are depressions and flatness on the surface of the gear disk to be measured;

[0018] Step 6: The electric telescopic rod in the tooth detection component is used to push the movable block to expand and contract, so that the pressing detection sensors on the movable block and the adjusting block are tightly pressed against the top surface of the tooth and the bottom surface of the tooth groove of the gear disk to be measured, and detect whether there are missing teeth and the spacing between teeth.

[0019] In summary, the beneficial effects of the present invention are as follows:

[0020] 1. By adopting a replaceable shaft center component, it is convenient to install different types of gear discs on the drive component and keep the shaft center the same as that of the turntable.

[0021] 2. The drive component drives the gear disc to be measured to rotate, and the rotating gear disc presses the auxiliary detection component, thereby facilitating the detection of the surface of the gear disc.

[0036] As Figure 3As shown, the placement component 1 includes a detection table 11. A through hole 12 is provided at the middle position of the detection table 11, and the driving component 2 is fixedly installed at the position of the through hole 12.

And through the turntable 23, it is convenient to drive the gear disc to rotate. Through the electromagnet 25, it is convenient to adsorb and fix the gear disc. The electromagnet 25 is electrically connected to the external control system through an external conductive slip ring, and through the anti-slip ring 26, it is avoided that the gear disc generates displacement on the turntable 23 when rotating and driving the gear disc, improving the detection precision.

[0038] As Figure 4 shown, the shaft center component 3 includes a shaft rod 31. A threaded rod 32 is fixedly installed at the lower end of the shaft rod 31, and the threaded rod 32 is threadedly connected to the driving component 2. The upper end of the shaft rod 31 is of a frustum-shaped structure, and the diameter of the lower end of the shaft rod 31 matches the shaft hole of the to-be-detected gear disc. Through the threaded rod 32, it is convenient to install the shaft rod 31 and convenient to replace shaft rods 31 with different thicknesses.

[0039] As Figure 5As shown, the tooth detection component 4 includes a mounting plate 41. The mounting plate 41 is fixedly installed on one side of the placement component 1, and an electric telescopic rod 42 is fixedly installed on the upper surface of the mounting plate 41.

The lead screws 46 are threadedly connected to the adjusting block 45. Through the lead screws 46, it is convenient to adjust the distance between the movable block 43 and the adjusting block 45, and thus it is convenient to detect different teeth and tooth grooves, improving the applicability when detecting different specifications of gear discs. And the displacement of the movable block 43 is controlled by the electric telescopic rod 42, which is convenient to move the movable block 43 and the adjusting block 45 towards the tooth direction to detect the tooth position. And when it contracts, it avoids affecting the rotation of the gear disc, and each gear tooth is detected one by one, improving the detection accuracy.

The slide rod 44 coincides with the slide hole 47, and the slide rod 44 is inserted into the interior of the slide hole 47.

When the pressing does not trigger a V shape, such as when the pressing type detection sensor 413 at the tooth groove position is triggered while the pressing type detection sensor 413 at the tooth end position is not triggered, it is judged that the tooth is abnormal, which is convenient for detection use.

When the detection gear disk rotates, the detection gear disk presses the ball 57, thereby compressing the spring 56, and the lifting seat 55 presses the auxiliary push-type inductor 54. When there is a defect on the surface of the gear disk, due to the stretching of the spring 56, the pressing on the auxiliary push-type inductor 54 is released, thereby judging that there is a depression on the surface of the gear disk, which is convenient for detecting the surface.
