Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft detection, in particular to a gear shaft slot detection device. Background Art

[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. Generally, it is a metal round rod, and each section can have a different diameter. The parts that make rotary motion in the machine are installed on the shaft.

[0003] As Figure 1 shown, a slot is opened at the bottom end of the gear shaft. In the actual processing process, there is a situation where the slot is missed in processing, which in turn leads to the disqualification of the gear shaft. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a gear shaft slot detection device. An object detection device and a distance detection device detect whether a gear shaft is connected in a sleeve, and the distance from the support plate to the gear part on the gear shaft, and judge whether a slot for clamping a limiting rod connected to the bottom of the sleeve is opened at the bottom of the gear shaft.

[0005] The utility model is realized through the following technical solutions:

[0006] A gear shaft slot detection device includes a platform and a circulating conveyor belt, and also includes a fixed seat and a gear shaft. The circulating conveyor belt is connected to the bottom of the platform. Several fixed seats are connected to the circulating conveyor belt and movably connected to the platform. A sleeve is fixedly connected to the top of the fixed seat. The gear shaft is placed in the sleeve. On the platforms on both sides of the circulating conveyor belt near the gear processing area, brackets are fixedly connected. A reference plate and a support plate are respectively connected to the two brackets. An object detection device and a distance detection device are connected to the support plate.

[0007] Further, an annular groove is provided on the top of the platform, and the circulating conveyor belt is connected to the bottom surface of the annular groove. The circulating conveyor belt includes a motor and a conveyor belt.

[0008] Further, a stabilizing device is connected to the conveyor belt of the circulating conveyor belt, and the fixed seat is connected to the stabilizing device.

[0009] Further, the inner shape of the hole of the sleeve is adapted to the shape of the gear shaft.

[0010] Further, a slot is opened at the bottom of the gear shaft, and a limiting rod that can be clamped in the slot is fixedly connected to the bottom of the hole of the sleeve.

[0011] Further, the reference plate and the support plate fixedly connected to the two brackets are parallel to each other and oppositely arranged in the horizontal direction.

[0012] Further, the distance between the reference plate and the support plate is consistent with the width of the gear portion on the gear shaft.

[0013] Further, the object detection device and the distance detection device are ultrasonic sensors.

[0014] Further, the object detection device and the distance detection device are on the same horizontal plane and are sequentially arranged on the support plate in the moving direction of the conveyor belt of the circulating conveyor belt. The detection end of the distance detection device faces the edge near the lower part of the gear portion on the gear shaft.

[0015] Compared with the prior art, the utility model has the following obvious advantages:

[0016] First, since the limiting rod is fixedly connected to the bottom of the sleeve in the utility model, when the gear shaft is placed into the sleeve, the limiting rod is clamped in the card slot opened at the bottom of the gear shaft, which limits the position and state of the gear shaft in the horizontal direction, and the operation of limiting the position of the gear shaft is simpler and more accurate.

[0017] Second, since the gear shaft is detected by the object detection device before moving to the distance detection device in the utility model, it is judged whether there is a gear shaft in the sleeve, and the situation that the distance detection data exceeds the preset data range caused by the absence of a gear shaft in the sleeve is excluded in advance.

[0018] Third, since the object detection device and the distance detection device are used in the utility model, before the gear shaft enters the processing area, it is measured whether the distance between the support plate and the gear portion on the gear shaft is within the preset numerical range, so as to judge whether the position height of the gear shaft on the sleeve is normal and screen out the gear shafts without the bottom groove of the gear shaft.

[0025] The present utility model will be introduced in detail below with reference to the accompanying drawings.

[0026] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model provides a gear shaft groove detection device, including a platform 1, a circulating conveyor belt 2, a stabilizing device 3, a fixing seat 4, a sleeve 5, a gear shaft 6, a bracket 7, a reference plate 8, a support plate 9, an object detection device 10, and a distance detection device 11; in this embodiment, an annular groove adapted to the width of the stabilizing device 3 is provided at the top of the platform 1, the circulating conveyor belt 2 includes a motor and a conveyor belt, the circulating conveyor belt 2 is fixedly connected to the bottom surface of the annular groove, several fixing seats 4 are connected to the circulating conveyor belt 2 and movably connected to the top surface of the platform 1, the bottom and one side surface of the fixing seat 4 are connected to the stabilizing device 3, the stabilizing device 3 is connected to the conveyor belt of the circulating conveyor belt 2, the inner shape of the hole of the sleeve 5 is adapted to the shape of the gear shaft 6, a groove 601 is provided at the bottom of the gear shaft 6, and a limiting rod 501 that can be engaged with the groove 601 is connected to the bottom of the hole of the sleeve 5.

[0027] Brackets 7 are fixedly connected to the platforms 1 on both sides of the circulating conveyor belt 2 near the gear processing area, a reference plate 8 and a support plate 9 are respectively fixedly connected to the two brackets 7, the reference plate 8 and the support plate 9 are parallel to each other and oppositely arranged in the horizontal direction, the distance between the reference plate 8 and the support plate 9 is consistent with the width of the gear part on the gear shaft, the object detection device 9 and the distance detection device 10 are ultrasonic sensors, the object detection device 10 and the distance detection device 11 are on the same horizontal plane, and are sequentially arranged on the support plate 9 according to the moving direction of the conveyor belt of the circulating conveyor belt 2, and the detection end of the distance detection device 11 faces the edge near the lower part of the gear part of the gear shaft 6.

[0028] When the present utility model is in use, after the gear shaft 6 is processed with a groove at the bottom, the gear shaft 6 is moved to the gear pre-processing area, and the gear shaft 6 is placed in the sleeve 5 fixedly connected to the fixing seat 4. The groove 601 at the bottom of the normally processed gear shaft 6 is engaged with the limiting rod 501 fixedly connected to the bottom of the hole of the sleeve 5. There may also be a situation where the groove 601 is not processed, and the limiting rod 501 supports the gear shaft 6; after the gear shaft 6 is placed, the circulating conveyor belt 2 is started, and the fixing seat 4 is driven to move towards the gear processing area. The stabilizing device 3 restricts the horizontal position of the fixing seat 4 to keep the fixing seat 4 stable during the movement. When the fixing seat 4 moves to the object detection device 10, if the object detection device 10 detects that there is a gear shaft 6 passing by, the distance detection device 11 is turned on. If it is not detected that there is a gear shaft 6 arranged in the sleeve 5, an alarm prompt is triggered and the transmission is stopped.

[0029] As Figure 4As shown, when the gear shaft 6 moves to the detection position of the distance detection device 11, if a card slot 601 is provided at the bottom of the gear shaft 6, then as Figure 4 shown in case a in Figure 4 , the detection end of the distance detection device 11 is facing the edge near the lower part of the gear part on the gear shaft 6. The detection end emits ultrasonic waves to the gear and reflects back. The detection end receives the reflected acoustic wave signal, obtains the distance L1 from the support plate 9 to the gear part on the gear shaft 6. If the detected distance data is within the preset value range, it can continue to be transmitted into the gear processing area.

[0030] If the card slot 601 is not machined at the bottom of the gear shaft 6, then as Figure 4 shown in case b in Figure 4 , the limiting rod 501 abuts against the bottom of the gear shaft 6. The gear shaft 6 is movably connected above the limiting rod 501. The detection acoustic wave emitted by the distance detection device 11 cannot propagate to the gear part on the gear shaft 6. The ultrasonic wave emitted by the detection end propagates to the reference plate 8 and reflects back. The detection end receives the reflected acoustic wave signal, obtains the distance L2 from the support plate 9 to the reference plate 8. If the detected distance data exceeds the preset value range, an alarm is triggered to prompt the operator and stop the transmission. The operator takes out the gear shaft 6 from the sleeve 5, checks the situation at the bottom of the gear shaft 6, confirms that the card slot 601 is not provided at the bottom of the gear shaft 6, and sends the gear shaft 6 back to the grooving processing area for reprocessing.
