Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a feeding device for processing the inner hole of a nut. Background Art

[0002] The feeding of nut inner hole processing is divided into horizontal pushing or longitudinal feeding. The longitudinal feeding is composed of a material frame with materials sorted, a feeding device and a processing device. The nuts are sorted one by one in the material frame, and the material frame is located above the processing device. The feeding device is a plug rod, which is inserted into the inner hole of the nut through a moving mechanism, and then lowered by a lifting mechanism after removing the nut, and then the nut is sent into the processing device through a moving mechanism, and then the plug rod is pulled out from the inner hole of the nut, and the processing device processes the inner hole of the nut.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: although the insertion rod can be very conveniently inserted into the inner hole of the nut, the size cannot be matched, resulting in low material collection success rate and poor material discharge accuracy. Utility Model Content

[0004] The main purpose of the utility model is to provide a feeding device for processing the inner hole of a nut, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The nut inner hole processing and feeding device includes a back plate, a telescopic cylinder is fixed to the bottom end of the back plate side wall, an extrusion rod is fixed to the telescopic end of the telescopic cylinder, a top plate is fixed to the position of the back plate above the telescopic cylinder, an L-shaped base rod is fixed to the bottom of the top plate, and a plurality of mounting holes are drilled on the back plate above the top plate, and splints are provided on both sides of the L-shaped base rod away from one end of the top plate, and a plurality of elastic parts are fixed to the outer walls of both ends of the L-shaped base rod close to the splint, and a rotating frame is fixed to the inner wall of the splint close to one end of the extrusion rod, and a concave roller is rotatably connected to the interior of the rotating frame.

[0007] Preferably, the extrusion rod is conical.

[0008] Preferably, the extrusion rod is inserted between the two concave rollers and contacts them.

[0009] Preferably, the telescopic ends of the elastic member are respectively fixed to one side close to the splint.

[0010] Preferably, outer grooves are carved on the outer walls of the splints.

[0011] Preferably, the interior of the outer grooves is bonded with anti-slip rubber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When taking materials, the moving mechanism drives the two clamping plates to pass through the inner hole of the nut, and then the telescopic cylinder drives the extrusion rod to be inserted between the two concave rollers after working, and squeezes the concave rollers through its cone surface, so that the two clamping plates are stretched and expanded through the elastic parts. The two clamping plates can expand and clamp the nuts, which not only enables the nuts to be smoothly removed from the material rack, but also can adapt to nuts with different inner hole sizes for taking materials according to the length of the extrusion rod end passing through the concave roller, which has good practicality.

[0014] 2. During feeding, the movement of the moving mechanism sends the nut into the processing device. The retraction of the telescopic cylinder after work drives the extrusion rod to pass through between the two concave rollers, and the length becomes shorter. After losing the expansion force of the extrusion rod, the two splints can shorten the distance between them through the tension of the elastic member, so that the two splints can be pulled out from the inner hole of the nut through the movement of the moving mechanism, thereby increasing the feeding accuracy.
