Description

Double-head lathe structure improvement

This creation relates to machining equipment for shaft parts, in particular to double-head lathes.

In the mechanical manufacturing industry, the cutting process of the shaft end face is a common process. In the prior art, the common lathe is used for the end face machining of the workpiece. This ordinary lathe can only be processed in one direction, if the workpiece needs to be bidirectional When processing, only one end of the workpiece can be cut and processed at the other end, and the other end is cut. For the operator, the feeding operation is continuously performed, so that the working intensity is large and the efficiency is very low.

The purpose of this creation is to provide a double-head CNC lathe with high efficiency of loading and unloading.

The above technical purpose of the creation is achieved by the following technical solutions: A double-head lathe structure improvement includes a seat plate on which a chuck is mounted, a chucking mechanism for loading a pair of chucks, and a feeding mechanism for returning one pair of chucks; the loading mechanism includes a width a type air gripper and a top rod, the wide air gripper is provided with a roller that feeds and guides the material, and the top rod pushes the material along the roller to the chuck; the feeding mechanism includes a conveyor belt for the output material and a pair of cards The chucking claw of the tray is fed to the belt, and a power source for driving itself is mounted at a lower belt surface of the belt and the power source is slid in the direction of the belt.

By adopting the above technical solution, the loading mechanism and the unloading mechanism respectively are the raw materials to be processed and the processed materials after the chuck is placed; the rollers of the wide pneumatic claws clamp the axial materials, and the advantage is that the transmission is The method uses the cylinder to pierce the shaft material for positioning, and then pushes into the chuck. However, due to the gap between the shaft material and the round hole, the shaft material is shaken left and right, and the center of the chuck cannot be accurately aligned, which is easy to cause the shaft to be difficult to be The chuck clamping causes the processed shaft material to be scrapped, which reduces the production efficiency, and the above-mentioned shaft material swaying problem is effectively solved by the clamping and lowering action of the roller, and the loading efficiency of the shaft material is improved; For a long time, the first end of the shaft material is bound to be relatively curved. The traditional cylindrical positioning method has poor fitting performance. When the bending of the shaft material is large, the shaft material is easily stuck at the cylinder, so that the shaft material advances. Stopping the process, reducing the efficiency, and the compressibility of the gas itself, the force of the shaft to the roller will make the gas in the cylinder lightly compress, so that the shaft of the bending part can slide into the chuck at the roller, avoiding The shaft is at the roller Dead, improved feeding efficiency of the shaft material.

The clamp gripper transports the processed shaft material from the chuck to the drive belt, which speeds up the blanking rate and improves the efficiency of the blanking. The belt surface of the belt is driven from top to bottom, and the lower belt is when the belt is below.

The power source of the traditional transmission belt is placed at the end, and the power source tensions the conveyor belt to limit the belt conveying path; when the power source is placed below the lower belt surface, changing the position of the power source does not affect the transmission state of the belt, and the power source is adjusted. The lower position makes it easy to adjust the space under the belt, so that the receiving frame of different conveying materials can be placed under the belt according to the demand, which improves the efficiency of collecting the shafting (cutting). And when the transmission belt is damaged, it needs to be repaired, and the position of the power source can be adjusted according to the working conditions, so that two or more people can be under the transmission belt for maintenance, improve the maintenance efficiency surface, and make the lathe repair as soon as possible, the lathe Production as soon as possible is conducive to improving production efficiency.

Preferably, the loading mechanism is disposed on the right side of the chuck, the wide air gripper includes two claws, and each of the claws is symmetrically arranged with at least two rollers, and the top rod is placed on the right side of the roller. The ejector rod is directed toward the bayonet of the chuck.

By adopting the above technical solution, the two rollers are used to determine the characteristics of a straight line by using two points, and the axial direction of the four rollers of the two claws is used to axially position, thereby further limiting the movement of the shaft material to the chuck. It prevents the offset of the shaft material and improves the efficiency of feeding. The ejector rod pushes the shaft material in the claw into the chuck. Preferably, the ejector rod is driven by the top cylinder to reciprocate toward the bayonet, and the top cylinder is fixed to the seat plate.

By adopting the above technical solution, vertical cylinder control and lateral cylinder coordination control The wide cylinder clamps the shaft material from the struts, and then the wide cylinder moves the shaft material to the center of the chuck. This step has higher loading efficiency than manual discharge. The top material mechanism places the single material of the shaft material on the support frame one by one, which facilitates the quick clamping of the wide cylinder and improves the feeding efficiency.

Preferably, the top material mechanism comprises a storage hopper, the sliding side of the storage hopper is provided with a sliding plate, and the top of the sliding plate is provided with a slope inclined to the side wall, and the lower end of the sliding plate extends out of the storage hopper to connect the upper cylinder through the fish eye joint; The upper top cylinder is pushed to the highest position of the sliding plate, and the inclined surface is placed on the same side as the top surface of the side wall, and the inclined surface is guided to the lower support frame.
