Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tool equipment, in particular to a material receiving device for a numerical control machine tool. Background Technique
[0002] A numerical control machine tool, abbreviated as a CNC machine tool, is an automated machine tool equipped with a program control system. The control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier. After being processed by arithmetic operations, various control signals are sent out by the numerical control device to control the actions of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. The numerical control machine tool better solves the problems of processing complex, precise, small-batch, and multi-variety parts. It is a flexible and high-efficiency automated machine tool, representing the development direction of modern machine tool control technology and being a typical mechatronic product.
[0003] For existing numerical control machine tools, manual blanking is required after processing, which is rather cumbersome. For some equipment with a material receiving function, only a rubber pad is provided inside the material receiving box for shock absorption and buffering during the blanking process. However, when multiple workpieces fall into the material receiving box, collisions may occur between the workpieces, which may very likely cause damage or even destruction of the workpiece surface. Therefore, we design a material receiving device for a numerical control machine tool to solve the above technical problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a material receiving device for a numerical control machine tool to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A material receiving device for a numerical control machine tool includes a material receiving box, a carrier box, a first mounting rack, and a second mounting rack. Symmetrically arranged L-shaped fixing plates are provided on the left and right side surfaces of the carrier box. A rotating shaft is provided between the inner side wall of the L-shaped fixing plate and the outer side wall of the carrier box. Electric push rods are symmetrically arranged on the left and right sides of the top of the first mounting rack. The output ends of the electric push rods vertically penetrate the first mounting rack downward and are connected with connecting blocks. The two connecting blocks are rotatably sleeved outside the corresponding rotating shafts. A convex block is provided at the top of the rear side surface of the carrier box. A wire winding control component is provided on the top of the second mounting rack. The wire winding control component is connected with the convex block through a pull rope. An inner plate is slidably arranged inside the carrier box. A plurality of first springs are evenly arranged at the bottom of the inner plate. The other ends of the first springs are connected with the inner bottom wall of the carrier box. A plurality of balls are movably arranged on the top of the inner plate. An auxiliary buffering component is further provided on the rear side wall inside the carrier box. Sponge layers are provided on the inner side walls of the material receiving box. The shortest distance between the rotating shaft and the front side surface of the carrier box accounts for one-third of the length of the carrier box.
[0007] As a preferred embodiment of the present utility model: The wire winding control assembly includes a housing fixedly arranged at the center of the top of the second mounting bracket. A wire winding roller is rotatably arranged inside the housing. The pulling rope is wound around the wire winding roller, and the other end of the pulling rope is connected to the convex block. A through hole for the pulling rope to pass through is opened at the bottom of the second mounting bracket, and the through hole is communicated with the inside of the housing. A motor is arranged on the outer surface of the housing, and the output shaft of the motor is connected to one end of the wire winding roller.
[0008] As a further preferred embodiment of the present utility model: The auxiliary buffer assembly includes a plurality of vertical plates, and the plurality of vertical plates are distributed at equal intervals in the horizontal direction. A plurality of second springs are connected between the vertical plates and the inner wall of the rear side of the load box, and a rubber pad is arranged on the front side surface of the vertical plate.
[0009] As a further preferred embodiment of the present utility model: Brake-equipped moving wheels are arranged at the four corners of the bottom of the material receiving box, and a push handle is arranged on the rear side surface of the material receiving box.
[0010] As a further preferred embodiment of the present utility model: The top of the material receiving box is designed with an open top, and the front side and the top of the load box are both designed with open tops. The load box is located below the first mounting bracket and the second mounting bracket.
[0011] As a further preferred embodiment of the present utility model: Both the first mounting bracket and the second mounting bracket are of U-shaped structures, and the bottoms of the first mounting bracket and the second mounting bracket are respectively installed on the ground through fixing bolts.
[0012] As a further preferred embodiment of the present utility model: The first mounting bracket and the second mounting bracket are arranged outside the material receiving box.
[0013] The beneficial effects of the present utility model are as follows: In this device, through the cooperative action of the L-shaped fixing plate, the rotating shaft and the connecting block, the carrier box body can rotate between the two connecting blocks. And since the shortest distance between the rotating shaft and the front side of the carrier box accounts for one-third of the length of the carrier box, under the influence of the self-weight of the carrier box, the rear end of the carrier box has a tendency to move downward. However, under the traction of the pulling rope, the rotation of the carrier box is restricted. Therefore, through the action of the wire winding control assembly, the carrier box can be controlled to maintain an inclined state with the front end slightly tilted upward, and the lifting of the carrier box can be controlled in this inclined state. When the workpiece falls into the carrier box, under the action of multiple ball bearings, the workpiece moves to the inside of the carrier box and collides with the rubber pad. Under the action of the rubber pad and the second spring, the movement of the workpiece is cushioned and buffered. Subsequently, the carrier box is controlled to descend into the inside of the receiving box. Then, through the wire winding control assembly, the pulling rope is further wound up, so that the rear end of the carrier box rises, that is, the carrier box starts to rotate, and the workpiece is poured out, enabling the workpiece to smoothly fall into the receiving box. The advantages of this device compared with the traditional device are as follows: Through each conveying of the workpiece, during the feeding process, the frequent collision between workpieces is greatly reduced, effectively protecting the surface accuracy of the workpiece, avoiding damage to the workpiece, and the overall operation process has a high degree of automation and high portability, which is worthy of popularization and use.

[0023] Please refer to Figures 1-6 , in the embodiment of the present utility model, a material receiving device for a numerical control machine tool includes a material receiving box 1, a load box 10, a first mounting bracket 3 and a second mounting bracket 4. The top of the material receiving box 1 is designed with an open mouth, and the front side and the top of the load box 10 are both designed with open mouths. The load box 10 is located below the first mounting bracket 3 and the second mounting bracket 4. Symmetrically arranged L-shaped fixing plates 19 are provided on the left and right side surfaces of the load box 10. A rotating shaft 18 is provided between the inner side wall of the L-shaped fixing plate 19 and the outer side wall of the load box 10. Both the first mounting bracket 3 and the second mounting bracket 4 are U-shaped structures. The bottoms of the first mounting bracket 3 and the second mounting bracket 4 are respectively installed on the ground through fixing bolts. This is a common existing technology, so no detailed explanation will be given here, and the fixing bolts are not shown in the figure. The first mounting bracket 3 and the second mounting bracket 4 are arranged outside the material receiving box 1. Electric push rods 8 are symmetrically arranged on the left and right sides of the top of the first mounting bracket 3. The output ends of the electric push rods 8 vertically penetrate the first mounting bracket 3 downward and are connected with connecting blocks 17. The two connecting blocks 17 are rotatably sleeved outside the corresponding rotating shafts 18. A convex block 20 is provided at the top of the rear side surface of the load box 10. A wire winding control assembly is provided at the top of the second mounting bracket 4. The wire winding control assembly is connected with the convex block 20 through a pulling rope 5. An inner plate 11 is slidably arranged inside the load box 10. A plurality of first springs 13 are evenly arranged at the bottom of the inner plate 11. The other ends of the first springs 13 are connected with the inner bottom wall of the load box 10. A plurality of balls 12 are movably arranged on the top of the inner plate 11. An auxiliary buffer assembly is further provided on the rear side wall inside the load box 10. Sponge layers are provided on the inner side walls of the material receiving box 1. The shortest distance between the rotating shaft 18 and the front side surface of the load box 10 accounts for one-third of the length of the load box 10.
[0024] The wire winding control component includes a housing 6 fixedly arranged at the center of the top of the second mounting bracket 4. A wire winding roller 22 is rotatably arranged inside the housing 6. A pull rope 5 is wound around the wire winding roller 22. The other end of the pull rope 5 is connected to a convex block 20. A through hole for the pull rope 5 to pass through is opened at the bottom of the second mounting bracket 4. The through hole is communicated with the inside of the housing 6. A motor 7 is arranged on the outer surface of the housing 6. The output shaft of the motor 7 is connected to one end of the wire winding roller 22. When the motor 7 is started, the motor 7 drives the wire winding roller 22 to rotate, thereby realizing the wire releasing operation of the pull rope 5. Similarly, when the motor 7 rotates in reverse, the wire winding operation of the pull rope 5 is realized.
[0025] The auxiliary buffer component includes a plurality of vertical plates 15. The plurality of vertical plates 15 are evenly distributed at equal intervals in the horizontal direction. A plurality of second springs 21 are connected between the vertical plates 15 and the inner wall of the rear side of the load box 10. A rubber pad 9 is arranged on the front surface of the vertical plate 15.
[0026] Brake-equipped moving wheels 2 are arranged at the four corners of the bottom of the material receiving box 1. A push handle 16 is arranged on the rear surface of the material receiving box 1. This design facilitates the movement of the material receiving box 1 and improves the convenience of using the device.
[0027] The load box 10 in this device is used to transport workpieces. And when the load box 10 rises to the highest position, the load box 10 is located below the discharge port of the numerical control machine tool, which is convenient for receiving the workpieces coming out of the discharge port of the numerical control machine tool. This is a common working process in this field and is easy to achieve.
[0028] Specifically, in this device, through the cooperative action of the L-shaped fixing plate 19, the rotating shaft 18, and the connecting block 17, the main body of the load box 10 can rotate between the two connecting blocks 17. Also, since the shortest distance between the rotating shaft 18 and the front side of the load box 10 accounts for one-third of the length of the load box 10, under the influence of the self-weight of the load box 10, the rear end of the load box 10 has a tendency to move downward. However, under the traction of the pull rope 5, the rotation of the load box 10 is restricted. Therefore, through the action of the wire winding control component, the load box 10 can be controlled to maintain an inclined state with the front end slightly tilted upward, and the lifting of the load box 10 can be controlled in this inclined state. When the workpiece falls into the load box 10, under the action of multiple balls 12, the workpiece moves to the inside of the load box 10 and collides with the rubber pad 9. Under the action of the rubber pad 9 and the second spring 21, the movement of the workpiece is cushioned and buffered. Subsequently, the load box 10 is controlled to descend into the inside of the receiving box 1. Then, the wire winding control component continues to wind the pull rope 5, so that the rear end of the load box 10 rises, that is, the load box 10 starts to rotate, and the workpiece is dumped out, enabling the workpiece to smoothly fall into the receiving box 1. The advantages of this device compared with traditional devices are as follows: Through each conveying of the workpiece, during the feeding process, the frequent collision between workpieces is greatly reduced, effectively protecting the surface accuracy of the workpiece, avoiding damage to the workpiece, and the overall operation process has a high degree of automation and high portability, which is worthy of popularization and use.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
