Description

Technical Field

[0001] The utility model relates to the technical field of automatic gear processing, in particular to a device for identifying whether a gear has been processed. Background Technique

[0002] In the process of automatic gear processing, usually a manipulator is used to take the processed gear from the processing equipment and place it on the conveyor belt, and then take the unprocessed gear from the conveyor belt and place it on the processing equipment for processing. To ensure that the gear placed on the processing equipment has not been processed, it must be detected before the manipulator takes it from the conveyor belt, so as to judge whether the gear has been processed.

[0003] The common methods for identifying whether a gear has been processed are manual identification or photoelectric identification. Its biggest disadvantage is that manual identification relies too much on personal ability and is prone to missed identification due to distraction. Photoelectric identification mainly judges by identifying the distance with light. It requires that when the gear to be detected moves along the conveyor belt, the circumferential position should be the same each time. Similarly, the circumferential position of the gear to be detected on the processing equipment must also be fixed. Only in this way can the manipulator take the processed gear from the processing equipment and place it on the conveyor belt to ensure that the circumferential position is the same each time. Therefore, the placement of the gear to be detected on the processing equipment and the conveyor belt has particularly strict requirements, increasing the difficulty of implementation. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above deficiencies and provide a device for identifying whether a gear has been processed. Through this device and method, as long as the gear to be detected drives the detection gear to rotate when moving along the conveyor belt, the two gears automatically enter the meshing state, and the distance between the signal sending bracket and the signal sending switch will not cause the signal sending switch to send a signal. However, when the gear to be detected has not been processed and moves along the conveyor belt, it cannot mesh with the detection gear but the outer circles are in contact with each other. At this time, the center distance between the gear to be detected and the detection gear increases, and the distance between the signal sending bracket and the signal sending switch becomes smaller, causing the signal sending switch to send a signal, thereby identifying that the gear to be detected has not been processed. The whole process is simple to operate, convenient to use, accurate in detection, and has a wider application.

[0005] In order to achieve the above technical features, the object of the present utility model is achieved as follows: A device for identifying whether a gear is processed, including a support. One end of the head of the support is provided with a U-shaped groove. A pin shaft is vertically installed between the U-shaped grooves. A gear for detection is rotatably installed on the pin shaft through a first bearing. The gear for detection is arranged inside the U-shaped groove. The other end of the support is rotatably installed on a support shaft through a second bearing and a third bearing. The bottom end of the support shaft is fixedly installed on the top of a base. A spring for tensioning it is connected to the tail of the support, and the other end of the spring is connected to the base. A signal sending device is fixedly installed on the inner side wall of the support through a signal sending bracket. The signal sending device cooperates with a signal sending switch and detects the swing of the support. The signal sending switch adopts a fixed installation method.

[0006] Step grooves are symmetrically machined on both sides of the center of the gear for detection. A gland is positioned and installed inside the step grooves. The glands at both ends are fixedly connected by a plurality of groups of uniformly arranged screws. The gland presses the outer ring of the first bearing.

[0007] The first bearing adopts a deep groove ball bearing;

[0008] On the outside of the pin shaft and symmetrically at both ends of the inner ring of the first bearing, spacer sleeves are installed.

[0009] The bottom end of the pin shaft is fixed by a first washer and a first bolt.

[0010] The second bearing and the third bearing adopt tapered roller bearings and are installed symmetrically in the reverse direction.

[0011] A second washer and a second bolt for fixedly pressing the second bearing are fixedly installed at the top end of the support shaft.

[0012] The bottom end of the support shaft is fixed by a third washer and a third bolt.

[0013] An annular groove for positioning the third bearing is machined on the support shaft. The annular groove supports on the top end of the base.

[0014] A bolt hole is provided at the tail of the support. One end of the spring is fixed by a limit bolt fixed on the bolt hole.

[0015] The present utility model has the following beneficial effects:

[0016] 1. The utility model is mainly applicable to identifying whether a gear is processed. Manual identification commonly used is prone to missed identification, while optoelectronic identification has particularly strict requirements for the placement position of the gear to be detected, increasing the difficulty of implementation.

The whole process is simple to operate, convenient to use, and accurate in detection, and is widely applied in the automated production of gears.

[0017] 2. By adopting the above - mentioned deep - groove ball bearing, it is ensured that the detection gear can rotate smoothly, and further, during the detection process, it is ensured that the detection gear can be driven to rotate smoothly by the gear to be detected.
