Description

Technical Field

[0001] This utility model relates to the field of centerless lathe technology, and in particular to an automatic feeding centerless lathe. Background Technology

[0002] As a crucial piece of equipment in modern precision manufacturing, the background technology of automatic feeding centerless lathes integrates multiple factors, including the upgrading needs of the manufacturing industry, advancements in automation technology, and process innovation. The following is an analysis of the background technology of this equipment: The limitations of traditional machining methods include inefficiency and reliance on manual labor. Early ordinary lathes required skilled workers to manually clamp workpieces and adjust parameters, resulting in high labor intensity and limited production capacity. Poor precision consistency led to significant fluctuations in machining quality due to reliance on operator experience, resulting in persistently high scrap rates. Statistics from a hardware factory show that dimensional deviations caused by manual loading and unloading accounted for 18%. Low material utilization results in approximately 15% scrap loss from the center hole process of centerless lathes, especially for precious metals or special alloys. The aerospace industry has experienced significant increases in raw material procurement costs due to this issue. Prominent safety hazards are also present. The open structure exposes high-speed rotating workpieces, and approximately 32% of workplace injuries reported annually in the domestic machinery industry are related to lathe operation.

[0003] In modern industrial production, the demand for machining rotating parts is increasing. Traditional lathe machining methods often require frequent manual clamping of workpieces, which is not only inefficient but also makes it difficult to guarantee the stability of machining accuracy. Therefore, we propose an automatic feeding centerless lathe to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding centerless lathe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic feeding centerless lathe includes: a lathe table and a support frame.

A square block is slidably mounted inside the support frame. The transmission wheel is rotatably connected to the square block. A fixed motor is fixedly mounted inside the lathe table.

[0011] In this invention, an automatic feeding centerless lathe uses a fixed motor to drive a worm gear, which in turn rotates the worm wheel. This, via a connecting rod, converts the rotational motion of the rotating disk into the reciprocating linear motion of the sliding block. This allows for adjustment of the distance between the two transmission wheels to accommodate different types of raw materials and deliver them to the processing position. A servo motor drives a threaded rod to rotate, and two oppositely oriented threaded grooves on the rod cause a T-shaped block to move the clamping block synchronously closer to or further away. Combined with a rubber pad, this provides flexible clamping force, achieving stable positioning. In this invention, an automatic feeding centerless lathe uses a hydraulic cylinder to push a fixed protective shell downwards, causing the cutting tool to contact the workpiece. A large motor drives the tool to rotate at high speed to complete the cutting. A water sprayer uses a water pump to spray coolant for cooling, and waste liquid and debris flow into a collection box through a horizontal plate for recycling. The equipment drives the workpiece to rotate via friction or directly through a transmission wheel, combined with axial positioning by a clamping block, achieving centerless grinding without a center / chuck, suitable for the efficient production of long shaft parts. This utility model has a reasonable structural design. Through the cooperation of multiple structures, it realizes the automated coordination of feeding, rotation, clamping and cutting. It can adapt to workpieces of different sizes, the clamping force is adjustable to avoid deformation, and it can significantly improve production efficiency and processing accuracy. The coolant circulation and waste collection system reduce pollution. Attached Figure Description
