Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tool loading equipment, in particular to a numerical control machine tool loading structure capable of automatic positioning. Background Art

[0002] CNC machine tools are short for Computer numerical control machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing. When the CNC machine tool is operating, a suitable feeding structure needs to be used.

[0003] The prior art has the following deficiencies: the prior art "an automatically positioned CNC machine tool loading structure" with publication number CN220825708U "includes a frame, the frame is mounted on the outer wall of the CNC machine tool, a material storage device is provided on the side of the frame away from the CNC machine tool, moving devices are mounted on the upper surfaces of both sides of the frame, loading devices are mounted on the moving devices, conveying devices are mounted on the inner walls of both sides of the frame, and a feeding device is mounted on the conveying device";

[0004] The above structure ensures that the loading can be carried out normally through the coordination between the frame, the material storage device, the moving device and other structures. However, the structure uses the traditional mechanical clamping positioning mode, the positioning is not accurate enough, and the position of the material storage structure is fixed. Filling the raw materials requires the operator to move to the position of the material storage structure, and the filling process is not convenient enough.

[0005] The prior art has the following problems:

[0006] The material storage structure of the loading equipment of conventional automatic positioning CNC machine tools is bound to the loading structure and cannot be moved flexibly. It is located in the central range of the equipment's operating position. At this position, the loading operator needs to enter the equipment's operating range, which is not only inconvenient but also involves certain risks. In addition, the current mechanical positioning loading method is not accurate enough. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a CNC machine tool loading structure capable of automatic positioning, which solves the existing problems of inconvenient filling of raw materials and inaccurate mechanical positioning.

[0008] To achieve the above object, the utility model provides the following technical solutions: a CNC machine tool loading structure capable of automatic positioning, comprising a main frame, a cushion block, and a mounting base, wherein the cushion block is arranged at the bottom end of the main frame, and the mounting base is arranged at the bottom end of the cushion block;

[0009] A longitudinal axis motor is also arranged inside the mounting base, a transverse axis motor is arranged at the side end of the main frame, a swing arm mechanism is arranged on one side of the middle part of the main frame, a loading barrel is penetrated through the inner end of the swing arm mechanism, and a limit plate is arranged below the swing arm mechanism and connected to the main frame;

[0010] The swing arm mechanism also includes a rotating connecting block, an axle column, a positioning axle seat and a laser locator. The rotating connecting block is fixedly connected to the left end of the swing arm mechanism, the axle column penetrates the side wall of the main frame and the rotating connecting block and extends to the other end to penetrate the other side wall of the main frame, the positioning axle seat is movably connected to the end of the axle column, and the laser locator is fixedly installed on the bottom surface of the other side of the swing arm mechanism near the end.

[0011] As a preferred technical solution of the utility model, the loading barrel also includes a sealing cover and an electric control valve port. The inner end of the sealing cover is provided with six groups of columnar structures, and is movably connected to the top end of the loading barrel through the structure. The electric control valve port is fixedly installed at the bottom end of the loading barrel.

[0012] As a preferred technical solution of the utility model, the laser locator is connected with the longitudinal axis motor and the electric control valve port through a line inside, and they can be linked to each other through electrical signals.

[0013] As a preferred technical solution of the utility model, the identification data of the laser locator is a height distance, and the height value is determined by the height between the specific CNC machine tool surface and the loading position. The specific identification value is the distance from the loading position to the laser locator, and this value can be changed by pre-editing.

[0014] As a preferred technical solution of the utility model, the longitudinal axis motor only provides a small rotation, and the main frame and the swing arm mechanism can swing 30 degrees to the left and right through the longitudinal axis motor, and the laser locator follows the swing arm mechanism to move in an arc.

[0015] As a preferred technical solution of the utility model, when the horizontal axis motor drives the shaft column to rotate, the swing arm mechanism can only rotate within a maximum range of 90 degrees.

[0016] As a preferred technical solution of the utility model, the end face of the limit plate is provided with two holes, one large and one small, whose positions correspond to the upper electric control valve port and the laser locator respectively, and the longitudinal axis motor passes through the pad block and is movably connected to the main frame.

[0017] Compared with the prior art, the utility model provides a CNC machine tool loading structure that can automatically position, which has the following beneficial effects:

[0018] This kind of automatic positioning CNC machine tool loading structure is provided with a longitudinal axis motor, a transverse axis motor, a swing arm mechanism and a loading barrel. When the equipment is automatically loading, the shaft column is first driven to rotate by the transverse axis motor, and the shaft column drives the rotating connecting block and the swing arm mechanism connected thereto until the swing arm mechanism rotates to an upright state and stops. At this time, the loading barrel is placed horizontally. After the operator puts the raw material into the loading barrel, the swing arm mechanism and the loading barrel are reset by the transverse axis motor. Then the main frame is driven by the longitudinal axis motor to swing slightly. In this process, the main frame drives the swing arm mechanism and the limit plate to swing in the same direction. At this time, the laser locator follows the swing arm mechanism to make an arc movement. Since the position to be loaded is higher than the surface of the CNC machine tool, the laser locator sends an electrical signal to the electric control valve port and the longitudinal axis motor when it recognizes the highly consistent position. The longitudinal axis motor stops rotating, and the electric control valve port opens for quantitative loading. The raw material falls into the fixed loading position through the hole of the limit plate to complete the automatic positioning and loading task. Through the above process, the equipment can have the following advantages:

[0019] 1. Before the loading operation begins, the material storage structure (the loading barrel in this solution) needs to be filled. This solution can directly drive the swing arm mechanism to move through the horizontal axis motor, so that the loading barrel moves in front of the operator. The operator does not need to go to the center of the equipment to complete the raw material filling, which provides convenience and reduces safety hazards;

[0020] 2. The laser locator used in this equipment recognizes the material based on the set height, and links the longitudinal axis motor with the electric control valve port to help the equipment to position and load the material more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A longitudinal motor 4 is also provided inside the mounting base 3, and the longitudinal motor 4 drives the main frame 1 to rotate.

[0031] In this embodiment, the loading barrel 7 also includes a sealing cover 701 and an electric control valve port 702. The inner end of the sealing cover 701 is provided with six groups of columnar structures, and is movably connected to the top of the loading barrel 7 through the structure.

By setting up the laser locator 604, the longitudinal axis motor 4, and the electric control valve port 702 with a wired connection relationship, the laser locator 604 can be linked to work; the recognition data of the laser locator 604 is the height distance, and the height value is determined by the height between the specific CNC machine tool surface and the loading position.

At this time, the loading barrel 7 is placed horizontally. After the operator puts the raw material into the loading barrel 7, the swing arm mechanism 6 and the loading barrel 7 are reset by the horizontal axis motor 5. Then the main frame 1 is driven by the longitudinal axis motor 4 to swing slightly. In this process, the main frame 1 drives the swing arm mechanism 6 and the limit plate 8 to swing in the same direction. At this time, the laser locator 604 follows the swing arm mechanism 6 to make an arc movement. Since the position to be loaded is higher than the surface of the CNC machine tool, the laser locator 604 sends an electrical signal to the electric control valve port 702 and the longitudinal axis motor 4 when it recognizes the highly consistent position. The longitudinal axis motor 4 stops rotating, and the electric control valve port 702 opens for quantitative loading. The raw material falls on the fixed loading position through the hole of the limit plate 8 to complete the automatic positioning and loading task.
