Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms of tapping machines, in particular to a feeding mechanism of a tapping machine with a guide structure. Background Art

[0002] A tapping machine is a mechanical processing equipment that processes internal threads, screws or threads on the inner surface of the through hole of a component. It is widely used in the machinery manufacturing industry. When using a tapping machine, it needs to be fed with the help of a tapping machine feeding mechanism. The tapping machine feeding mechanism refers to a device used to feed the workpiece into the tapping machine. It usually consists of a feed shaft, a feed nut, a feed gear, a feed motor and other parts. The feed shaft is a rotating shaft, which feeds the workpiece into the tapping machine through the transmission of the feed nut and the feed gear. The feed motor provides power to rotate the feed shaft. By adjusting the speed and feed amount of the feed shaft, the feed speed and depth of the workpiece can be controlled, thereby achieving precise tapping processing.

[0003] However, when the existing feeding mechanism is in use, most of the materials are still manually fed. In order to improve the feeding efficiency, the materials are often placed on the conveyor belt at random, resulting in inconsistent material positions during feeding, and the materials cannot be accurately fed to the lower end of the tapping machine. During processing, special attention must be paid to the feeding, which delays the overall feeding speed and reduces the processing efficiency. Utility Model Content

[0004] The utility model aims to provide a tapping machine feeding mechanism with a guide structure to solve the problem that the position of the material on the conveyor belt is not uniform during feeding in the prior art, and the material cannot be accurately delivered to the lower end of the tapping machine body.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A tapping machine feeding mechanism with a guiding structure comprises a base, a conveyor belt and a tapping machine body, the conveyor belt is installed above the base, and brackets are symmetrically arranged on both sides of the front end of the conveyor belt, and the tops of the corresponding sides of the two brackets are connected with electric telescopic rods, and the telescopic ends of the electric telescopic rods are arranged opposite to each other and are connected with guide plates, and the ends of the two guide plates facing the transmission direction of the conveyor belt are both in the shape of arcs bent inwards; a fixing mechanism is arranged on the conveyor belt; pillars are symmetrically arranged on both sides of the conveyor belt on the base, and the tapping machine body is connected to the two pillars through a lifting mechanism, so that the tapping machine body can move up and down along the pillars above the fixing mechanism; an infrared sensor is arranged on the bottom end surface of the tapping machine body, and a controller is arranged above the tapping machine body, and the conveyor belt, the fixing mechanism, the lifting mechanism, the tapping machine body and the infrared sensor are all electrically connected to the controller.

[0007] A further technical solution is that the fixing mechanism includes two fixing frames, which are respectively arranged on opposite sides of the conveyor belt. The tops of the corresponding sides of the two fixing frames are connected to electric drive rods, and the telescopic ends of the electric drive rods are relatively arranged and are both connected to limit plates.

[0008] A further technical solution is that sliding grooves are vertically opened on the corresponding sides of the two pillars, and screw rods are vertically rotated in the sliding grooves. The lifting mechanism includes a driving motor, which is arranged at the top of the pillar. The output end of the driving motor passes through the rotating hole and penetrates into the sliding groove, and is connected to the screw rod. A slider matching the screw rod thread is provided on the screw rod; the two ends of the tapping machine body are respectively connected to the sliders at the corresponding ends.

[0009] A further technical solution is that rotating bearings are fixedly provided at both ends of the sliding groove, the outer rings of the two rotating bearings are respectively connected to the groove walls at the upper and lower ends of the sliding groove, and the two ends of the screw rod are respectively fixedly connected to the inner rings of the two rotating bearings.

[0010] A further technical solution is that rubber blocks are evenly arranged on the surface of the conveyor belt.

[0011] Compared with the prior art, the beneficial effects of the utility model are: 1. By setting a guide plate with an inwardly curved arc at the tail end, when the component body is transported by the conveyor belt, the guide plate can guide the component body to the middle end position on the conveyor belt, which is convenient for the subsequent fixing mechanism to fix and limit the tapping operation.

[0012] 2. Install the guide plate through the electric telescopic rod. When facing component bodies of different sizes, the telescopic length of the telescopic end of the electric telescopic rod can be controlled, and then the distance between the two guide plates can be controlled, so that the distance between the tail ends of the two guide plates is directly opposite the middle position of the conveyor belt, thereby ensuring that the component body can be located at the middle end of the conveyor belt after being guided by the guide plate, which is convenient for the subsequent fixing mechanism to fix the limit and perform tapping operations.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Embodiment 1:

The tops of the two brackets 4 corresponding to one side are connected with electric telescopic rods 5. The telescopic ends of the electric telescopic rods 5 are arranged opposite to each other and are connected with guide plates 6. The ends of the two guide plates 6 facing the conveying direction of the conveyor belt 2 are both in the shape of an arc that is bent inwards; a fixing mechanism is arranged on the conveyor belt 2; pillars 7 are symmetrically arranged on both sides of the conveyor belt 2 on the base 1, and the tapping machine body 3 is connected to the two pillars 7 through a lifting mechanism. The tapping machine body 3 is moved up and down above the fixing mechanism along the support 7. When the fixing mechanism fixes the component body 18, the tapping drill bit 19 of the tapping machine body 3 is located directly above the component body 18. An infrared sensor 8 is provided on the bottom end surface of the tapping machine body 3, and a controller 9 is provided above the tapping machine body 3. The conveyor belt 2, the fixing mechanism, the lifting mechanism, the tapping machine body 3 and the infrared sensor 8 are all electrically connected to the controller 9. In actual use, the utility model controls the telescopic length of the telescopic end of the electric telescopic rod 5 according to the size of the component body 18, adjusts the distance between the tail ends of the two guide plates 6, and ensures that the two The distance between the tail ends of the guide plates 6 is directly opposite to the middle end of the conveyor belt 2, so that the component body 18 can just pass through the tail ends of the two guide plates 6, thereby ensuring that the component body 18 is at the middle end of the conveyor belt 2 after passing through the guide plates 6, and continues to be transported through the conveyor belt 2. By arranging an infrared sensor 8 on the bottom end surface of the tapping machine body 3, when the component body 18 is transported along the conveyor belt 2 to the bottom of the infrared sensor 8, the infrared sensor 8 transmits the signal to the conveyor belt 2, the fixing mechanism, the lifting mechanism and the tapping machine body 3 through the controller 9, the conveyor belt 2 stops conveying, and the fixing mechanism works to fix the component body 18. The lifting mechanism drives the tapping machine body 3 to descend and automatically tap the component body 18. After the tapping operation of the component body 18 is completed, the controller 9 transmits signals to the conveyor belt 2, the fixing mechanism, the lifting mechanism and the tapping machine body 3 respectively, the fixing mechanism releases the component body 18, the lifting mechanism drives the tapping machine body 3 to rise away from the component body 18, and the conveyor belt 2 starts to continue to convey the component body 18, thereby completing the cycle, and then the component body 18 can be automatically tapped, reducing safety hazards. At the same time, the operator can also quickly feed the material through the conveyor belt 2, greatly improving the work efficiency. The guide plate 6 is connected by the electric telescopic rod 5, and the distance between the tail ends of the two guide plates 6 can be adjusted according to the size of the component body 18, so as to avoid that when the component body 18 is too small and the distance between the two guide plates 6 is large, the component body 18 is not in the middle position of the conveyor belt 2 after being guided by the guide plate 6, and at the same time, when the size of the component body 18 is too large, the distance between the tail ends of the two guide plates 6 is fixed, and the component body 18 cannot pass through the distance, affecting the conveying of the conveyor belt 2.
