Detailed Description

The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.

Example (b):

a full-automatic double-spindle loading and unloading device is shown in figure 1 and comprises a double-spindle clamp 2 used for clamping a workpiece 1 for machining. The double-spindle clamp 2 is a common structure on a numerically controlled lathe, and can clamp the workpiece 1 and rotate the workpiece 1. The double-spindle clamp 2 is horizontally provided with a slide rail 3, and the slide rail 3 is arranged above the double-spindle clamp 2 through a fixing plate 12. The fixing plate 12 can improve the efficiency of assembly, and facilitate maintenance and repair of parts.

One end of the slide rail 3 is fixed with a push-pull cylinder 4, and the other end of the slide rail 3 is fixed with a reverse push cylinder 5. The slide rail 3 is slidably provided with a slide block assembly 6. Two horizontal material supporting clamps 10 are installed on the sliding block assembly 6, the height of each material supporting clamp 10 is the same as that of the discharge groove 8, and the material supporting clamps 10 are driven by the push-pull air cylinder 4 to move back and forth at positions where the material supporting clamps 10 are over against the discharge grooves 8 and the material supporting clamps 10 are over against the double-spindle clamp 2. Referring to fig. 1 and 2, the slider assembly 6 slides on the slide rail 3, changing the position of the material holding jig 10. Two material supporting clamps 10 are respectively arranged on the sliding block component 6.

A feeding chute 7 and a discharging chute 8 are fixed at the end part of the slide rail 3 close to the reverse thrust cylinder 5, and the feeding chute 7 is communicated with the discharging chute 8. The rear end of the discharge chute 8 is provided with a feeding cylinder 9, and of course, the feeding cylinder 9 also has a blocking function so as to ensure that each action ensures that a single workpiece 1 is fed from the feed chute to the discharge chute 8 and then enters the material supporting clamp 10. Go up silo 7 and blown down tank 8 and form an contained angle, go up silo 7 slope setting, the one end of going up silo 7 is vibration dish entry 14. The workpiece 1 can be fed into the feeding groove 7 through the vibrating disk, and the feeding groove 7 feeds the workpiece 1 at a corner position through the feeding air cylinder 9 by the gravity of the workpiece 1.

And a material beating cylinder 11 is arranged at the clamping position of the workpiece 1 opposite to the double-spindle clamp 2, and the material beating cylinder 11 is used for sending the workpiece 1 in the material supporting clamp 10 into the double-spindle clamp 2. Corresponding position detection can be provided on the knockout cylinder 11. The material supporting clamp 10 is provided with a clamping hole 13 for the workpiece 1 to enter the clamping connection, and the telescopic shaft of the knockout cylinder 11 extends into the clamping hole 13 during working. When the material supporting clamp 10 is located at a corresponding position, the material beating cylinders 11 act, the two material beating cylinders 11 act simultaneously, the telescopic shafts send the workpiece 1 into the double-spindle clamp 2 from the material supporting clamp 10, and the double-spindle clamp resets after work is completed.

Referring to fig. 2, the end of the slide rail 3 is further provided with a buffer block 15, and the buffer block 15 abuts against the slider assembly 6. The buffer block 15 is fitted at the end of the slide rail 3 through a movable rod at the rear end, and the movable rod is connected with a buffer spring, which is not shown in the drawing. When the surface of the buffer block 15 is rubber. In the moving process of the sliding block component 6, the sliding block component is abutted to the buffer block 15, so that the kinetic energy of the push-pull air cylinder 4 can be prevented from being overlarge, and the reverse push air cylinder 5 also has the same action effect and can buffer the power of the push-pull air cylinder 4.

The workpiece 1 is not required to be clamped and started and stopped manually and repeatedly, and the clamping is finished automatically by a control system. Because of the humanized reduction artifical intensity of labour of structure, reduced the personnel selection cost of enterprise.

The workpieces 1 to be processed are arranged and orderly enter the inlet 14 of the vibration disk and slide in one material at a time. And (5) waiting after the material is detected by a numerical control system PLC. After the double manipulators return, the material supporting clamp 10 is pushed into the material supporting clamp 10 by the material feeding cylinder 9, then the material supplementing process is repeated, after the material in the material groove is detected, the reverse pushing cylinder 5 is pushed forward to be in place, then the workpiece 1 to be processed is pushed into the material supporting clamp 10, the numerical control system PLC judges that the material feeding is finished and waits, a material feeding completion signal is given to the system, and at the moment, the material supporting clamp 10 waits at the position closest to the main shaft. When the numerical control system needs to feed materials, the system is controlled, the material supporting clamp 10 moves to the front of a main shaft chuck, and the material beating cylinder 11 pushes the workpiece 1 into the chuck in place and clamps the workpiece. And (3) starting a turning program after the double-head manipulator detects and returns, receiving the popped processed workpiece 1 by a receiving groove after the processing is finished, and sliding out of the back of the machine tool to enter the containing box. The automatic operation is circulated by a numerical control system.

And the material supporting clamp 10 completes material supplement one by one on the slide rail 3, so that the material supplement of the material supporting clamp 10 is realized at one inlet, and after the material supplement, the turning is finished at the position closest to the turning area. The feeding is finished on the same linear guide rail before the chuck, and the butt joint step is direct, accurate and ingenious. The processing time is not occupied, and the efficiency is improved.

Compared with the prior double-vibration disk for double main shafts, the double-vibration disk has the advantages of greatly reduced cost, reduced noise of working environment, space saving and reduced feeding intensity. Compared with the prior upper and lower structure, the horizontal feeding device has strong visibility and does not shield, observe, debug and set the cutter. The ergonomics principle is fully considered in the structure, the feeding height and the whole structure are parallel and level with the main shaft, the distance between the feeding height and the whole structure and the main shaft is 1 meter away from the ground, and the manual labor intensity is greatly reduced, so that the operation and the fault removal are easier and more convenient.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
