Material receiving device

Abstract

The invention provides a material receiving device and belongs to the technical field of automatic lathes. The material receiving device solves the technical problems that when an existing material receiving device is used in the material receiving process, a workpiece is easy to damage, and the material receiving performance of the existing material receiving device is poor. The material receiving device is installed on a machine frame and comprises a material cover frame and a material pipe, wherein the material cover frame is arranged in a front-and-back communicating mode, and the materialpipe is arranged in the material cover frame and can move in the material cover frame. The top of the material pipe is connected with the material cover frame. A notch is formed in the bottom of thematerial pipe. A material receiving plate is arranged in the notch, wherein one end of the material receiving plate is hinged to the material pipe and can be opened or closed together with the material pipe. A roller shaft is arranged in the material cover frame, and the material receiving plate is arranged on the roller shaft. When the material pipe moves on the material cover frame, the materialreceiving plate moves on the roller shaft, and the material receiving plate and the material pipe are enabled to be opened or closed. The material receiving device has the beneficial effects that inthe falling process of workpieces, the inertia of the workpieces is small, the impact between the workpieces is reduced, the friction between the workpieces and the material receiving plate is small,the abrasion of the material receiving plate and workpieces is small, and the service life of the material receiving plate is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automatic lathes, and relates to a material receiving device. Background technique [0002] Pneumatic manipulator is an automatic operation device that can imitate certain actions and functions of human hands and arms to grab, carry objects or operate tools according to a fixed program. It can replace human heavy labor to realize mechanization and automation of production, and reduce human labor. Labor intensity, save production cost, it can operate in harmful environment to protect personal safety, at the same time, pneumatic manipulator as a kind of manipulator, it has simple structure, light weight, fast action, stable, reliable, energy saving and no pollution to the environment, etc. Advantages, and thus widely used in various industries. [0003] At present, pneumatic manipulators are also widely used on lathes and machine tools in various automated production lines. In practical applications, these...

Problems solved by technology

[0003] At present, pneumatic manipulators are also widely used on lathes and machine tools in various automated production lines. In practical applications, these lathes or machine tools are often equipped with feeding devices for feeding and receiving devices for unloading. , the feeding device, the material receiving device and the pneumatic manipulator cooperate to make the automatic production line more convenient and fast. For example, the utility model patent of CN201172171 Y discloses a kind of automatic pipe cutting machine material receiving device, including the bracket installed on the pipe cutting machine tool body , the bracket is provided with a feeding trough with openings at both ends, and a feeding tray is arranged on the feeding trough, and the feeding tray can slide on the feeding trough, and a cylinder is fixedly installed on the feeding chute, and the piston of the cylinder is fixedly connected with the feeding tray, which This kind of material receiving device can meet the dual requirements of material receiving and unloading, and can directly transfer the workpiece to the storage box, which improves the processing efficiency of the pipe cutting machine, but at the same time has the following shortcomings: 1. When unloading, the material receiving tray Moving to the rear end on the feeding trough, a large inertia will be generated during the movement. When the receiving tray moves to the predetermined position and stops, the workpiece on the receiving tray will fall under the inertia with a force greater than itself Into the storage box, the falling workpiece and the workpiece in the storage box will have a greater impact, causing the two workpieces to be hard hit and damaged at the same time, greatly affecting the quality of the workpiece; 2. This material receiving device passes the material The tray moves on the feeding trough to realize the feeding function. The receiving tray is open. After the workpiece is processed, it will directly fall into the receiving tray and automatically slide into a fixed position. Generally, the workpiece is higher than the receiving tray. When the workpiece falls into the When it is on the receiving tray, the workpiece and the receiving tray are hard-impacted, which not only easily damages the processed workpiece, affects the quality of the workpiece, but also causes the deformation of the receiving tray, and the deformation of the receiving tray will make the bottom of the receiving tray and the feeding The friction of the trough makes the movement of the receiving tray on the feeding trough inflexible, which greatly affects the use of the receiving device; 3. The workpiece falls from the processing end into the trough, and under the impact, some workpieces will form on the trough. Bounce and fall out of the trough, and picking up the workpiece adds unnecessary trouble, so there are obvious defects in the function of receiving and unloading the material receiving tray, and its receiving and unloading functions are greatly reduced
