Description

Technical Field

[0001] The present application relates to the technical field of machining auxiliary equipment, and in particular to an automatic material receiving and unloading device for a CNC lathe. Background Art

[0002] CNC lathes are widely used in the machining industry, mainly for machining shaft parts. After the parts are machined, they are cut off by a cutting knife. However, during the cutting process, the parts are easily damaged by falling, which not only affects the machining quality of the parts, but also may cause damage to the lathe. In order to solve this problem, manual access or simple mechanical assistance (such as pallets) is usually used for access.

[0003] However, the above method is relatively inefficient and there are potential safety hazards during the operation of the staff. Utility Model Content

[0004] In order to improve the efficiency of material receiving and reduce the potential safety hazards of workers during the material receiving process, the present application provides an automatic material receiving and unloading device for a CNC lathe.

[0005] The present application provides an automatic material receiving and unloading device for a CNC lathe using the following technical solution:

[0006] An automatic material receiving and unloading device for a CNC lathe, comprising a swing arm rotatably connected to the side wall of a lathe machining chamber and a material receiving hopper rotatably mounted at one end of the swing arm away from its own rotation axis, the material receiving hopper being used to receive workpieces, the lathe being provided with a material discharge window connected to the lathe machining chamber, a material storage tray being arranged at a position corresponding to the material discharge window on the outside of the lathe, and rotating the swing arm can drive the material receiving hopper to approach the material storage tray or to approach a chuck of the lathe for clamping the workpiece.

[0007] By adopting the above technical solution, during the workpiece processing, the swing arm is controlled by the PLC program to rotate automatically, so that the receiving hopper is close to the chuck. After the workpiece is cut, it falls into the receiving hopper. Then, when the swing arm rotates, the receiving hopper is close to the discharge window, and the receiving hopper is rotated, so that the workpiece in the receiving hopper falls on the storage tray, completing the automatic receiving and unloading of the workpiece, improving production efficiency, and reducing safety hazards.

[0008] Optionally, the receiving hopper is a conical structure with a hollow interior, and an opening is provided at a large end of the receiving hopper.

[0009] By adopting the above technical solution, the receiving hopper is set to be conical, which makes it convenient for workpieces to fall into the receiving hopper.

[0010] Optionally, a plurality of water outlets are evenly arranged on the receiving hopper.

[0011] By adopting the above technical solution, during the workpiece processing, the cutting fluid needs to be sprayed on the workpiece, and the cutting fluid will fall into the receiving hopper during the process of receiving the workpiece. The cutting fluid flows out through the water outlet. On the one hand, it is convenient for the circulation of the cutting fluid, and on the other hand, it can reduce the situation where the cutting fluid follows the movement of the workpiece and flows to the outside of the lathe.

[0012] Optionally, a buffer is provided inside the receiving hopper, and the buffer is composed of a plurality of buffer plates fitted on the inner wall of the receiving hopper, and the buffer plates are made of flexible material.

[0013] By adopting the above technical solution, when the workpiece falls into the receiving hopper, the buffer plate provides a certain buffer to the workpiece, thereby reducing the occurrence of collision of the workpiece.

[0014] Optionally, the storage tray is a disc-shaped structure, which is horizontally arranged and can rotate around its own circumference.

[0015] By adopting the above technical solution, during the workpiece processing, the workpieces continuously fall onto the storage tray. By rotating the storage tray, the workpieces can fall onto different positions on the storage tray, thereby reducing the occurrence of workpiece accumulation and collision.

[0016] Optionally, a circular baffle ring is provided on the material storage tray, and the baffle ring is coaxially arranged above the material storage tray.

[0017] By adopting the above technical solution, the retaining ring is arranged on the material storage tray to form a barrier on the material storage tray, thereby preventing the workpiece from rolling and separating from the material storage tray.

[0018] Optionally, a rubber layer is provided on the inner side wall of the baffle ring and on the side of the storage tray facing away from the ground.

[0019] By adopting the above technical solution, buffer parts are arranged on the retaining ring and the storage tray to reduce the collision of the workpiece when it falls on the storage tray.

[0020] Optionally, a baffle is provided inside the baffle ring, and the baffle is fixed relative to the lathe. The internal space of the baffle ring is divided into two parts along a direction parallel to the baffle, wherein the side close to the swing arm is a material receiving chamber, and the part away from the swing arm is a material storage chamber. One side of the baffle is in contact with the inner wall of the baffle ring, and the other side is provided with a gap with the inner wall of the baffle ring to form a conveying channel.

[0021] By adopting the above technical solution, after the workpiece falls into the receiving cavity, the baffle can prevent the workpiece from continuing to roll, thereby reducing the occurrence of collisions between the workpiece and the workpiece in the storage cavity. The provision of the conveying channel enables the workpiece in the receiving cavity to move into the storage cavity during the rotation of the storage tray.

[0022] Optionally, a guide member is provided in the material storage tray, one end of the guide member extends into the material receiving cavity, and the other end extends into the lathe processing cavity. The material receiving hopper can dump the workpiece onto the guide frame member, and the guide member is used to guide the workpiece to roll in a direction close to the material storage tray.

[0023] By adopting the above technical solution, the receiving hopper and the storage tray are connected by a guide member, which facilitates the workpiece to roll onto the storage tray.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The swing arm rotates to drive the receiving hopper to receive the workpiece, and automatically transports the workpiece to the storage tray, realizing automatic receiving and unloading of the workpiece, improving efficiency, and reducing safety hazards during the work of the staff;

[0026] 2. A water outlet is provided on the receiving hopper so that the cutting fluid entering the receiving hopper can flow out, thereby reducing the cutting fluid from flowing onto the storage tray; BRIEF DESCRIPTION OF THE DRAWINGS

A discharge window 4 is provided on the lathe, and the discharge window 4 is connected to the machining chamber of the lathe. A storage tray 3 is provided at a position corresponding to the discharge window 4 on the outside of the lathe. The rotation of the swing arm 1 can drive the hopper to approach a chuck for clamping the workpiece in the machining chamber of the lathe or approach the discharge window 4. In this embodiment, the rotation of the swing arm 1 and the rotation of the receiving hopper 2 are driven by a servo motor. When the workpiece is about to be processed, the swing arm 1 rotates to drive the receiving hopper 2 to move to the bottom of the chuck, the cutting knife cuts the workpiece, the workpiece falls into the receiving hopper 2, and then the swing arm 1 drives the workpiece to approach the discharge window 4; at this time, the receiving hopper 2 is rotated to dump the workpiece in the receiving hopper 2 onto the storage tray 3, so as to realize automatic material receiving and unloading. Thereby, production efficiency is improved and safety risks of workers in the material receiving process are reduced.

[0034] Reference Figure 1 and Figure 2 The receiving hopper 2 is a conical structure as a whole, the interior of the funnel is hollow, and an opening is set on the large end surface to facilitate the receiving hopper 2 to receive the workpiece. The receiving hopper 2 is provided with a plurality of water outlet holes 21, and the plurality of water outlet holes 21 are evenly distributed on the receiving hopper 2, so that the cutting fluid in the workpiece cutting process can flow out from the water outlet holes 21.

The buffer member 22 is composed of a plurality of buffer plates bonded to the inner wall of the receiving hopper 2. The buffer plates are made of flexible material to reduce the possibility of injury when parts fall into the receiving hopper 2. In this embodiment, the buffer plates are made of rubber.

[0036] Reference Figure 1 and Figure 2 , the storage tray 3 is a disc-shaped structure, and the storage tray 3 is arranged horizontally. A support frame is arranged below the storage tray 3, and the storage tray 3 rotates around its own circumference and is connected to the support frame. In this embodiment, the storage tray 3 is directly driven by a servo motor. During the continuous processing of the workpiece, the storage tray 3 is driven by the servo motor to rotate, so as to reduce the occurrence of collisions caused by the accumulation of workpieces in one place. A retaining ring 5 is arranged above the storage tray 3, and the retaining ring 5 is a circular ring structure. The retaining ring 5 is coaxially welded on the storage tray 3 to prevent the workpiece from rolling to the outside of the storage tray 3. A rubber layer can be pasted on the storage tray 3 and on the inner side wall of the retaining ring 5 to reduce the occurrence of bumps in the process of the workpiece falling onto the storage tray 3.

[0037] Reference Figure 1 and Figure 2, a baffle assembly 6 is provided on the support frame, and the baffle assembly 6 includes a mounting frame 61 and a baffle 62, the mounting frame 61 is fixedly connected to the support frame, and the baffle 62 is installed on the mounting frame 61 and is located inside the baffle ring 5. The baffle 62 is arranged perpendicular to the radial direction of the storage tray 3, and the internal space of the baffle ring 5 is divided into two parts by the plane where the baffle 62 is located, wherein the part close to the lathe is the receiving cavity 63, and the part away from the lathe is the storage cavity 64. The receiving hopper 2 dumps the workpiece into the receiving cavity 63, and the baffle 62 can prevent the workpiece from rolling into the storage cavity 64, thereby reducing the collision between the workpieces. One side of the baffle 62 abuts against the inner wall of the baffle ring 5, and the other side is spaced from the inner wall of the baffle ring 5, so that a conveying channel is formed between the baffle 62 and the baffle ring 5. During the rotation of the storage tray 3, the workpiece moves with the storage tray 3 and moves through the conveying channel to the storage cavity 64.

[0038] Reference Figure 1 and Figure 2 The mounting frame 61 includes a connecting plate 611 and a column 612. The connecting plate 611 is horizontally arranged and one side is welded to the support frame. The column 612 is vertically welded above the connecting plate 611.

The opening of the guide 8 is away from the ground. One end of the guide 8 extends to the lathe processing cavity, and the other end extends to the receiving cavity 63. The height of the end of the guide 8 close to the storage tray 3 is lower than the height of the end of the guide 8 located in the lathe processing cavity. The receiving hopper 2 dumps the workpiece at the end of the guide 8 located in the lathe processing cavity. Under the action of the workpiece's own gravity, the workpiece automatically rolls into the receiving cavity 63, making it convenient for the receiving hopper 2 to place the workpiece in the receiving cavity 63. A water outlet 21 is also provided on the guide 8 to reduce the occurrence of cutting fluid flowing into the storage tray 3.

[0040] The implementation principle of an automatic material receiving and unloading device for a CNC lathe in an embodiment of the present application is as follows: during the workpiece processing, the PLC control program controls the servo motor to drive the swing arm 1 and the hopper to rotate, so that the receiving hopper 2 is directly below the workpiece, and the opening of the receiving hopper 2 is facing the workpiece.
