Description

Technical Field

[0001] The utility model relates to the technical field of numerical control lathes, and particularly relates to a feeding and storage device for a numerical control lathe. Background Technique

[0002] Numerical control lathes are mainly used for cutting and processing the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any cone angle, complex revolving inner and outer curved surfaces, cylindrical and conical threads, etc., and can also perform operations such as grooving, drilling, reaming, and boring. Before processing on a numerical control lathe, the workpiece needs to be clamped on the spindle fixture first, and then the spindle rotates and the tool feeds to cut the workpiece. There are two ways of workpiece feeding before clamping, manual and automatic. Manual feeding has low efficiency. Existing numerical control lathes usually set up automatic feeding devices. For example, the utility model patent with the application number of "202020329425.8" and the name of "A new numerical control lathe device with automatic feeding and discharging" pushes the workpiece in the storage box to the numerical control lathe through a feeding cylinder in its feeding mechanism. However, the structural setting of this patent occupies a large space, and when the length of the workpiece is slightly longer, the occupied space will be further increased, which is not conducive to equipment layout and needs to be improved to a certain extent. Content of the Utility Model

[0003] The purpose of the utility model is to provide a feeding and storage device for a numerical control lathe, which occupies a small space and is conducive to equipment layout.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A feeding and storage device for a numerical control lathe, including a numerical control lathe. A hollow shaft is horizontally arranged at the rear end of the numerical control lathe, and a coaxial hollow chuck is arranged at the front end of the hollow shaft. A storage box and a feeding conveying mechanism are arranged behind the numerical control lathe. The longitudinal section of the upper part of the storage box is trapezoidal with the upper part larger than the lower part. The lower part of the storage box is a blanking groove that can allow a single workpiece to pass through. A first through groove with a width smaller than the width of the bottom plate is arranged on the bottom plate of the blanking groove. Second through grooves for a single workpiece to pass through are arranged on the groove walls at the front and rear ends of the blanking groove, and the axis of the second through groove coincides with the axis of the hollow shaft. The feeding conveying mechanism includes a conveyor and a feeding push plate. The conveying plane of the conveyor is arranged below the blanking groove and runs back and forth. The feeding push plate is arranged on the conveying plane and penetrates through the first through groove and the second through groove along with the running of the conveying plane to push the workpiece in the blanking groove into the hollow shaft.

[0005] As a preference of this technical solution, the upper end of the feeding push plate is lower than the upper end of the single workpiece it pushes.

[0006] As a preference of this technical solution, a vibrator is arranged on the outer side wall of the storage box.

[0007] As a preference of this technical solution, two vibrators are arranged, and the two vibrators are respectively arranged on the upper part and the lower part of the storage box.

[0008] Preferably, the conveyor is a chain plate conveyor in this technical solution.

[0009] Compared with the prior art, a storage box and a feeding conveyor mechanism are arranged behind the numerical control lathe in the utility model. The storage box is arranged above the feeding conveyor mechanism. Workpieces to be processed are stored in the storage box. The workpieces are conveyed to the numerical control lathe through the feeding conveyor mechanism, achieving the purpose of automatic feeding. And this structural arrangement avoids the pushing device being arranged on one side of the storage box, reducing the space occupied by the device and being beneficial to the layout of other devices.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-6, a feeding and storage device for a numerically controlled lathe according to the present utility model, includes a numerically controlled lathe 1. A hollow shaft is horizontally arranged at the rear end of the numerically controlled lathe 1, and a coaxial hollow chuck 2 is arranged at the front end of the hollow shaft. The hollow shaft is used for workpiece conveying, and the hollow chuck 2 is used for workpiece clamping. A storage box 4 and a feeding conveying mechanism are arranged behind the numerically controlled lathe 1. The longitudinal section of the upper part of the storage box 4 is in a shape with a larger upper part and a smaller lower part. The lower part of the storage box 4 is a blanking groove that allows a single workpiece to pass through, and the blanking groove communicates with the upper part. A first through groove 4.1 with a width smaller than the width of the bottom plate is arranged on the bottom plate of the blanking groove. Both the front and rear ends of the first through groove 4.1 are open. Second through grooves 4.2 for a single workpiece to pass through are arranged on the groove walls at the front and rear ends of the blanking groove. The axis of the second through groove 4.2 coincides with the axis of the hollow shaft. The feeding conveying mechanism includes a conveyor 3 and a feeding push plate 5. The conveying plane of the conveyor 3 is arranged below the blanking groove and runs back and forth. The feeding push plate 5 is arranged on the conveying plane. The feeding push plate 5 penetrates through the first through groove 4.1 and the second through groove 4.2 as the conveying plane runs, and pushes the workpiece in the blanking groove into the hollow shaft.

[0019] When the present utility model is specifically implemented, the length directions of the storage box 4 and the conveyor 3 are the front-rear direction, that is, the left-right direction in the figure. The conveyor 3 is a chain conveyor. The conveyor 3 is located below the storage box 4. Both ends of the conveyor 3 protrude slightly from the storage box 4, that is, the length of the conveyor 3 is slightly greater than the length of the storage box 4, and the width is also slightly greater than the width of the blanking groove. The conveying plane is the upper plane, and the return plane is the lower plane. The upper plane of the conveyor 3 runs from left to right, that is, towards the numerically controlled lathe 1. The feeding push plate 5 is fixed in the middle of the conveying plane, and the upper end of the feeding push plate 5 is lower than the upper end of the single workpiece it pushes. A vibrator 6 is arranged on the outer side wall of the storage box 4. Two vibrators 6 are arranged, and the two vibrators 6 are respectively arranged on the upper and lower parts of the storage box 4, so that the workpieces in the storage box 4 can be smoothly discharged.

[0020] The working principle of the present utility model: Workpieces to be processed are placed in the storage box. A single workpiece reaches the bottom plate of the blanking groove from the blanking groove. When it is necessary to load the workpiece onto the numerically controlled lathe, the conveyor is started. The feeding push plate on the conveyor runs and penetrates through the first through groove and the second through groove, pushing the single workpiece in the blanking groove out of the storage box and inserting it into the hollow shaft from the rear end of the hollow shaft until one end of the workpiece extends out of the hollow chuck. After the hollow chuck clamps the workpiece, it can be processed. After the feeding push plate pushes the single workpiece out of the storage box, the previous workpiece falls onto the bottom plate of the blanking groove. The feeding push plate returns to the left end of the conveyor, and by repeating the above actions, other workpieces can be conveyed onto the numerically controlled lathe.

[0021] It should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. described above is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
