Description

Technical Field

[0001] The invention relates to the technical field of tooth top flatness detection equipment, in particular to a tooth top flatness detection equipment for gears. Background Art

[0002] Gears are a common mechanical component in our daily life. They are mainly used to transmit motion and power. However, in the process of gear production, some defective products are inevitable. Whether the tooth top of the gear is flat is an important criterion for judging whether the gear is qualified. The uneven tooth top will cause the gear to move unsteadily during the meshing process, thereby affecting the accuracy and consistency of the transmission. At the same time, the uneven tooth top will produce irregular impact force during meshing, which will cause greater noise and vibration, which not only affects the working environment, but may also damage the structure of the entire transmission system. Therefore, after the gear is produced, the flatness of its tooth top needs to be tested.

[0003] The reason why the gear with uneven tooth top is not stable during the movement and produces irregular impact force is mainly due to the presence of convexities or concaveness on the tooth top. Therefore, in the process of flatness detection of the tooth top of the gear, the main thing is to detect whether there are convexities or defects on the tooth top of the gear. However, in the existing technology, most of the staff use measuring tools to measure whether the distance between the center of the gear and the tooth top is uniform or use visual judgment to detect whether there are concave or convexities on the tooth top of the gear. However, since there are many teeth on the gear, if the measuring tool is used for measurement, not only the workload for the staff is large, but also the detection efficiency is low. However, if the visual judgment method is used for detection, then for some more subtle convexities, it will cause the staff to be unable to judge the detection results more intuitively, thereby reducing the accuracy of the detection results. At the same time, during the processing of the gear, dust or debris will be attached to the tooth top. If it cannot be cleaned, it will affect the detection results and the accuracy of the detection results. To this end, we provide a tooth top flatness detection device for gears to solve the above problems. Summary of the invention

[0059] Working principle: first, the gear to be tested is sleeved on the outside of the support pad 215, and then the threaded rod 208 is driven to rotate by starting the motor 1 207, thereby driving the threaded sleeve 209 to move upward, and the arc plate 211 can be unfolded by the rotation of the driving rod 210 and under the cooperation restriction of the guide rod 212 and the guide cylinder 213 until the support pad 215 contacts the inner surface of the gear, thereby fixing the gear.

Through the meshing with the bevel gear 1 203, the support rod 201 can be driven to rotate synchronously with the gear to be detected. Under the rotation of the gear, The gear tooth tops can be painted. After the painting is completed, the staff can start the electric telescopic rod 220 to drive the carrier plate 219 to move until the white paper strip fixed on the outer surface of the carrier plate 219 contacts the tooth top of the detected gear, and then start the motor 34 again to drive the rotation of the gear to be detected, and with the rotation of the support rod 201, the rack 216 can be driven to move.

With the rotation of the gear to be detected and the movement of the white paper strip, the color of each tooth top will change on the white paper strip. A specific pattern is printed on the colored paper strip. After the gear to be tested rotates one circle, the staff opens the box door 13 and takes out the white paper strip printed with color by pulling the clamping pad 222 outward. The printed pattern on the white paper strip can be used to intuitively judge whether the tooth top of the gear is flat. When there is a depression on the tooth top, there will be a blank area on the corresponding pattern. When there is a protrusion on the tooth top, only the pattern at the protrusion of the tooth top can be printed on the white paper strip.
