Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to an automatic tapping machine for eye nuts. Background Art

[0002] An eye nut is a component used to fasten a nut to a bolt or screw. It is an essential component for all manufacturing machinery. It is a commonly used fixture in construction projects. The nut has a threaded base, which can be drilled and secured with a screw thread according to different specifications.

[0003] A tapping machine is a machine tool that uses taps to create internal threads. It is the most widely used type of internal threading machine. According to national machinery industry standards, tapping machines are categorized into: desktop tapping machines, vertical tapping machines, and horizontal tapping machines. For some reason, an important and widely used category is not included: folding-arm tapping machines (hydraulic tapping machines, electric tapping machines, and pneumatic tapping machines).

[0004] When applying for the present invention, the applicant searched and found that a Chinese patent disclosed "an automatic nut tapping machine" with application number "202011445079.0". This patent mainly provides an automatic tapping device on one end surface of a station plate, and the automatic tapping device includes a tapping motor, thereby achieving automatic tapping with a high degree of automation, changing manual operation and improving efficiency. In addition, an intermittent auxiliary adjustment device is provided on the upper surface of a collection frame, and the intermittent auxiliary adjustment device includes a horizontal plate, thereby achieving intermittent auxiliary operation, improving the degree of automated processing, and automatically unloading after processing is completed, and automatically locking the limit during processing to prevent displacement during processing and damage to the tap. Automatic unloading avoids the effect of scalding the operator due to residual heat from tapping;

[0005] However, due to the irregular shape of the eye nut, clamping and positioning are difficult during the tapping process, and they can only be loaded and clamped manually one by one, taking about 10 minutes per workpiece, resulting in low labor efficiency and inability to ensure automated tapping. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides an automatic tapping machine for eye nuts, which solves the problem that automated tapping cannot be achieved.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic tapping machine for eye nuts, comprising a feeding box, a material elevator is provided on the side wall of the feeding box, a material sorting box is provided on the upper end of the material elevator, a pushing cylinder is provided inside the material sorting box, a slide rail is provided on the side wall of the material sorting box, a tapping machine is provided at the end of the slide rail away from the material sorting box, a material outlet is provided on the side wall of the tapping machine, and a spiral chip conveyor is provided on the rear side of the tapping machine.

[0008] Preferably, a diffuse reflection sensor is provided inside the material sorting box.

[0009] Preferably, the telescopic end of the pushing cylinder is provided with a swing arm, which is in a vertical shape when extended and in a swinging shape when retracted.

[0010] Preferably, a side groove is connected to the side of the material sorting box and located below the slide rail, and one end of the side groove away from the material sorting box is connected to the material feeding box.

[0011] Preferably, a pneumatic vibrator is provided at the bottom of the slide rail.

[0012] Preferably, the tapping machine includes a servo motor and a tap, and the tap is tapped by the servo motor.

[0013] Preferably, it further comprises a pressing cylinder, which is arranged below the tapping machine, and a stopper is provided at the telescopic end of the pressing cylinder.

[0014] Preferably, a display screen is provided at the upper end of the tapping machine.

[0015] The present invention provides an automatic tapping machine for eye nuts. It has the following beneficial effects:

[0016] 1. By setting a diffuse reflection sensor, a pushing cylinder and a swing arm inside the material sorting box, the diffuse reflection sensor is used to detect the number of eye nuts fed into the material sorting box. When the feeding is too much, the material elevator stops feeding. Secondly, under the action of the pushing cylinder, the pushing cylinder pushes the eye nut toward the slide rail. The swing arm mechanism (swing arm) at the front end of the pushing cylinder is vertical when pushing the material forward. When the pushing cylinder retreats, the swing arm swings to make way for the workpiece, thereby realizing automatic cyclic feeding of the eye nuts.

[0017] 2. By connecting a side groove on the side of the material sorting box and below the slide rail, and connecting the end of the side groove away from the material sorting box to the feeding box, the ring nuts with the ring facing downward slide down the slide rail, and the ring nuts with the ring facing upward fall from the end of the slide rail into the side groove below due to gravity, slide into the feeding box, and reload, to ensure that the rings of all the eye nuts are facing downward (that is, the tapping head is facing upward), which facilitates tapping.

[0018] 3. The overall structure is automated, eliminating the need for manual loading, thereby reducing workers' workload and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
