Description

Technical Field

[0001] This utility model relates to the technical field of vertical machining centers, specifically to an automatic unloading device for vertical machining centers. Background Technology

[0002] Vertical machining centers use a CNC system to precisely position and move each coordinate axis (usually X, Y, and Z axes) of the machine tool, while simultaneously controlling the spindle rotation speed and cutting feed rate. The workpiece is mounted on the worktable, and the cutting tool is mounted on the spindle. According to a pre-programmed machining program, the CNC system directs the machine tool to automatically perform cutting operations, including milling, drilling, boring, and tapping. After the vertical machining center completes the machining of the workpiece, it automatically unloads and transports the workpiece to the designated position, completing the unloading process.

[0003] However, existing technologies still have the following problems:

[0004] First, existing vertical machining centers using automatic unloading equipment often fail to maintain a simple structure while ensuring flexible movement and adjustment. If the design is complex, multiple steps may be required to complete the clamping action, increasing the difficulty of operation and time costs. Moreover, complex structures are prone to failure, reducing the reliability of the equipment. If a low-precision transmission method is used, errors are likely to accumulate, making it difficult to accurately reach the designated position. If the movement method is singular, it cannot quickly adapt to the unloading needs of different workpieces.

[0005] Secondly, existing vertical machining centers with automatic unloading equipment are not convenient for indirect storage of workpieces. Most lack dedicated workpiece storage devices, and the workpieces are piled up randomly after unloading, which can easily cause collisions and wear between workpieces. Especially for some precision-machined workpieces, even a slight collision can damage the workpiece and affect product quality.

[0006] To address the aforementioned problems, the inventors proposed an automatic unloading device for vertical machining centers. Utility Model Content

[0007] To address the issues of difficulty in ensuring both structural simplicity and flexible movement adjustment, as well as the inconvenience of indirect workpiece storage, the purpose of this invention is to provide an automatic unloading device for vertical machining centers.

[0008] To solve the above technical problems, this utility model adopts the following technical solution: an automatic unloading device for a vertical machining center, including a base, with brackets fixedly mounted on both sides of the upper end of the base. A reinforcing plate is fixedly mounted on one end of the same side of both brackets. A fixing groove is formed at one end of the reinforcing plate, and an adjusting frame is fixedly mounted on the inner wall of the fixing groove. A motor is mounted at one end of the adjusting frame, and a protective plate is fixedly mounted on the lower end of the outer surface of the motor. The protective plate is fixedly connected to the adjusting frame, and the protective plate provides protection and support for the motor. A lead screw is fixedly mounted on the output end of the motor through the adjusting frame. A movable block is threaded onto the outer surface of the lead screw. The outer surface of the movable block is in movable contact with the inner surface of the adjustment frame. Two clamping parts are provided on the lower part of one side of the movable block. A guide rail is provided on one side of one end of the movable block. Two electric sliders are slidably provided on one end of the guide rail. A support is fixedly provided on one end of the electric slider. A cylinder is fixedly provided on the upper inner wall of the support. The output end of the cylinder passes through the support and is fixedly provided with a lifting block. The two sides of the lower end of the support are rotatably connected to the two clamping parts respectively. Two rotating rods are rotatably connected between the two ends of the lifting block and the two clamping parts respectively.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figure 1-4As shown, this utility model provides an automatic unloading device for a vertical machining center, including a base 1. Supports 2 are fixedly mounted on both sides of the upper end of the base 1. A reinforcing plate 21 is fixedly mounted on one end of the same side of both supports 2. A fixing groove 24 is formed at one end of the reinforcing plate 21. An adjusting frame 3 is fixedly mounted on the inner wall of the fixing groove 24. A motor 31 is mounted at one end of the adjusting frame 3. The output end of the motor 31 passes through the adjusting frame 3 and is fixedly mounted on a lead screw 32. A moving block 33 is threaded onto the outer surface of the lead screw 32. Two clamping parts 39 are provided on the lower part of one side of the moving block 33. A guide rail 34 is provided on one side of one end of the moving block 33. The guide rail 34 is bolted to one end of the moving block 33. Two electric sliders 35 are slidably mounted on one end of the guide rail 34. A support member 36 is fixedly mounted on one end of each electric slider 35. The base 1 and the supports 2 form the frame structure of the machining center. The adjusting frame 3 is installed in the fixing groove 24 on the reinforcing plate 21. The material unloading operation is carried out through the adjusting frame 3. Specifically, after the workpiece is processed, the motor 31 is started. The output end of the motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 causes the moving block 33, which is threaded onto its outer surface, to move along the lead screw 32. The moving direction and position of the moving block 33 can be controlled by the forward and reverse rotation of the motor 31 and the running time, which constitutes the motion adjustment in the first direction. When the moving block 33 moves to the appropriate position, the electric slider 35 on the guide rail 34 starts to work. The electric slider 35 slides along the guide rail 34, driving the support 36 to move to the designated position. Through the cooperation of the lead screw 32, the moving block 33 and the electric slider 35, the clamping part 39 can be moved accurately in both horizontal and vertical directions, which improves the accuracy and efficiency of unloading and provides high flexibility of movement.

[0022] A cylinder 37 is fixedly installed on the upper inner wall of the support member 36. The output end of the cylinder 37 passes through the support member 36 and is fixedly installed with a lifting block 38. The two sides of the lower end of the support member 36 are rotatably connected to two clamping members 39 respectively. The two ends of the lifting block 38 are rotatably connected to two rotating rods 310 between the two clamping members 39 respectively. Then, the cylinder 37 is started, and the output end of the cylinder 37 pushes the lifting block 38 to move up and down. When the lifting block 38 moves, it drives the clamping members 39 to rotate through the rotating rods 310, thereby realizing the opening and closing action of the clamping members 39 to clamp or release the workpiece. The clamping structure is simple in design, easy to operate and reliable in use.

[0023] Four equally spaced support columns 22 are provided between the two brackets 2. A reinforcing block 23 is fixed on one side of the upper end of the adjustment frame 3, and one end of three of the support columns 22 is connected to the reinforcing block 23. The support columns 22 improve the connection strength between the two brackets 2, while the reinforcing block 23 provides support and protection for the adjustment frame 3.

[0024] Example 2: Figure 5As shown, a placement box 4 is fixedly provided at one end of the base 1. An inclined block 41 is fixedly provided on one side of the inner wall of the placement box 4. A soft pad 42 is fixedly provided at one end of the inclined block 41. The placement box 4 is located below one end of the adjustment frame 3. After the clamping member 39 clamps the workpiece, the motor 31 and the electric slider 35 work together again to move the workpiece above the placement box 4. Then, the cylinder 37 controls the clamping member 39 to release the workpiece, and the workpiece falls into the placement box 4. The inclined block 41 and the soft pad 42 in the placement box 4 play a buffering and guiding role, so that the workpiece can be placed stably in the placement box 4. The placement box 4, the inclined block 41 and the soft pad 42 are designed so that the workpiece after unloading can be properly placed and protected, and the workpiece is not damaged during the falling process.

[0025] Working principle: The base 1 and the bracket 2 form the frame structure of the machining center. The adjustment frame 3 is installed in the fixed groove 24 on the reinforcing plate 21. The material unloading is carried out through the adjustment frame 3. Specifically, after the workpiece is processed, the motor 31 starts. The output end of the motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 causes the moving block 33, which is threaded onto its outer surface, to move along the lead screw 32. The direction and position of the moving block 33 can be controlled by the forward and reverse rotation of the motor 31 and the running time, which constitutes the motion adjustment in the first direction. When the moving block 33 moves to the appropriate position, the electric slider 35 on the guide rail 34 starts to work. The electric slider 35 slides along the guide rail 34, driving the support 36 to move to the designated position. Through the cooperation of the lead screw 32, the moving block 33 and the electric slider 35, the clamping part 39 can be moved accurately in both the horizontal and vertical directions, which improves the accuracy and efficiency of unloading and provides high flexibility of movement.

[0026] Next, cylinder 37 is started, and the output end of cylinder 37 pushes lifting block 38 to move up and down. When lifting block 38 moves, it drives clamping member 39 to rotate through rotating rod 310, thereby realizing the opening and closing action of clamping member 39 to clamp or release workpiece. The clamping structure is simple in design, easy to operate and reliable in use.

[0027] The support column 22 increases the connection strength between the two brackets 2, while the reinforcing block 23 provides support and protection for the adjustment frame 3.

[0028] After the clamping member 39 clamps the workpiece, the motor 31 and the electric slider 35 work together again to move the workpiece above the placement box 4. Then, the cylinder 37 controls the clamping member 39 to release the workpiece, and the workpiece falls into the placement box 4. The inclined block 41 and the soft pad 42 inside the placement box 4 play a buffering and guiding role, so that the workpiece can be placed stably in the placement box 4. The placement box 4, the inclined block 41 and the soft pad 42 are set up so that the workpiece after unloading is indirectly stored, can be properly placed and protected, and avoids damage to the workpiece during the falling process.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
