Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and more particularly to a machine tool structure for optimizing the blanking space. Background Art

[0002] Machine tools play an increasingly important role in modern mechanical manufacturing and processing. Generally, parts with higher precision requirements and finer surface roughness requirements need to be finally processed by cutting methods on machine tools. With the development of industrial technology, the requirements for the machining capabilities of machine tools are also getting higher and higher. Therefore, in order to enrich the functions of machine tools and improve the machining efficiency, the types and quantities of cutting tools in machine tools are increased. However, when increasing the cutting tools, it will inevitably occupy the available space inside the machine tool.

[0003] For example, a kind of automatic loading and unloading device for machining disc-shaped parts disclosed in Chinese Patent with the publication number CN206550360U includes a frame, a ramp chute, a loading cylinder, a pushing cylinder, a blanking cylinder, and a receiving cylinder. The pushing cylinder and the blanking cylinder are oppositely arranged in the X direction of the frame. The ramp chute includes an inlet and an outlet. The inlet of the ramp chute is used to place blanks, and the outlet of the ramp chute is aligned with the blanking cylinder. A chuck is also fixedly arranged between the blanking cylinder and the outlet of the ramp chute. A loading cylinder is also fixedly arranged in the Y direction of the frame, and the loading cylinder is used to push the ramp chute to translate in the Y direction of the frame. A receiving cylinder fixed to the frame is also arranged below the blanking cylinder, and a receiving tray is connected to the receiving cylinder.

[0004] The above-mentioned prior art solutions have the following defects: Since the blanking device occupies the machining space inside the machine tool, the machining range of the machine tool is reduced and the space layout is unreasonable. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, one of the purposes of the present invention is to provide a machine tool structure for optimizing the blanking space, which has the advantage of optimizing the blanking space.

[0006] The above invention purpose of the present invention is achieved through the following technical solutions: A machine tool structure for optimizing the blanking space includes a bed body and a sub-spindle mechanism arranged on the bed body. An installation seat opposite to the sub-spindle mechanism is also arranged on the bed body. A power device is arranged on the installation seat, and a plurality of cutting tools are arranged on the power device. A blanking mechanism is arranged at a position on one side of the bed body where the sub-spindle mechanism is located. The blanking mechanism includes a guiding member rotatably connected to the bed body and a transmission mechanism connected to the bed body and located below the guiding member. The bottom end of the guiding member is connected with a linkage member, and the linkage member intermittently abuts against the sub-spindle mechanism.

[0007] By adopting the above technical solution, the sub-shaft mechanism can hold the workpiece and move it. First, the sub-shaft mechanism drives the workpiece to be processed on the tool of the power device. At this time, the material guiding member is in an outwardly flipped state. When blanking is required, the sub-shaft mechanism drives the workpiece to move towards the material guiding member. When the diameter of the workpiece is large, the sub-shaft mechanism contacts the linkage member and continues to push the linkage member to rotate, thereby driving the upper end of the material guiding member to continue to rotate towards the sub-shaft mechanism, so that the feeding port of the material guiding member can be exactly aligned with the sub-shaft mechanism, and at this time, the material guiding member does not collide with the tool close to the material guiding member, realizing the optimal utilization of space.

[0008] In a preferred example of the present invention, it can be further configured that: the material guiding member includes a material guiding cylinder whose bottom end is rotatably connected to the bed body. The material guiding cylinder is arranged in a tubular shape that penetrates up and down. The top of the material guiding cylinder is provided with a feeding port, and the opening direction of the feeding port faces the sub-shaft. The lower end opening of the material guiding cylinder is communicated with the transmission mechanism.

[0009] By adopting the above technical solution, after the sub-shaft mechanism drives the workpiece to the feeding port, the sub-shaft mechanism moves away, and the material guiding member flips outward again, so that the workpiece falls into the transmission mechanism through the feeding port and the material guiding cylinder, and is driven and sent out by the transmission mechanism.

[0010] In a preferred example of the present invention, it can be further configured that: the linkage member is rod-shaped. One end of the linkage member is connected to the side wall of the material guiding cylinder, and the other end extends towards the sub-shaft mechanism and can be in contact with the sub-shaft mechanism. The bed body is connected with a reset member for resetting the material guiding cylinder.

[0011] By adopting the above technical solution, when the sub-shaft mechanism moves towards the linkage member and contacts the linkage member, it can push the linkage member to rotate downward. Since the linkage member is fixedly connected to the material guiding cylinder, it can further drive the material guiding cylinder to rotate towards the sub-shaft mechanism, so that the feeding port is aligned with the workpiece of the sub-shaft mechanism, facilitating blanking.

[0012] In a preferred example of the present invention, it can be further configured that: an installation block is connected to the side wall of the material guiding cylinder. The end of the linkage member is rotatably connected to the installation block. The installation block is provided with an arc-shaped adjustment groove. The linkage member is tightened to the adjustment groove by a bolt. The arc-shaped groove is centered on the rotation center of the linkage member.

[0013] By adopting the above technical solution, when the size of the workpiece to be processed changes, loosen the bolt and rotate the linkage member. When the linkage member is rotated downward, the amplitude of the sub-shaft mechanism pushing the linkage member to rotate decreases, so that the amplitude of the material guiding cylinder swinging towards the sub-shaft mechanism decreases, thereby adapting to the blanking of the workpiece. When the linkage member is rotated upward, the amplitude of the sub-shaft mechanism pushing the linkage member to rotate increases, so that the amplitude of the material guiding cylinder swinging towards the sub-shaft mechanism increases, thereby adapting to the blanking of larger diameter workpieces.

[0014] In a preferred example, the present invention can be further configured as follows: the reset member includes a spring, one end of the spring is connected to the side wall of the bed, and the other end of the spring is connected to the top of the outer wall of the material guide cylinder and applies a force to rotate the material guide cylinder outward.

[0015] By adopting the above technical solution, when the secondary shaft mechanism presses against the material guide barrel and pushes the material guide barrel to rotate in the direction of the secondary shaft mechanism, the spring is in a stretched state. When the secondary shaft mechanism moves away, the material guide barrel can be pulled to rotate and reset under the resetting action of the spring, and the power device is used to achieve limiting, thereby preventing the material guide barrel from excessively turning outward.

[0016] In a preferred example, the present invention can be further configured as follows: the power device includes a power seat fixedly connected to the mounting seat, four tool seats for mounting the power head are installed on the side of the power seat facing the secondary shaft, the power seat is connected to a drive motor, and the drive motor is located on the side of the guide barrel away from the secondary shaft mechanism.

[0017] By adopting the above technical solution, one end of the tool holder extends into the power holder and is connected to a gear, and the other end of the tool holder extends out of the power holder and is used to install the tool. The drive motor drives the tool holder through the gear structure and drives the tool to rotate. Different types of tools, such as drills, milling cutters, etc., can be inserted on the tool holder, thereby making the workpiece processing more diversified and more adaptable.

[0018] In a preferred example, the present invention can be further configured as follows: the secondary shaft mechanism includes a base slidably connected to the bed, and the base is connected to the secondary shaft.

[0019] By adopting the above technical solution, the abutment plate is used in conjunction with the linkage member, so that when the base moves, the abutment plate is driven to move relative to the linkage member, and the linkage member is pushed to rotate downward, thereby driving the material guide barrel to rotate.

[0020] In a preferred example, the present invention can be further configured as follows: the transmission mechanism includes a conveyor belt arranged on the bed, the feed end of the conveyor belt is located below the opening of the guide cylinder, and the discharge end of the conveyor belt extends to the outside of the machine.

[0021] By adopting the above technical solution, the processed workpiece slides downward from the guide tube, falls onto the conveyor belt and is sent out by the conveyor belt, thereby realizing automatic feeding of the workpiece, making unloading more convenient, labor-saving and efficient.

[0022] In a preferred example, the present invention can be further configured as follows: a mounting groove is opened on the side of the bed, the bottom end of the material guide cylinder is hinged to the inner wall of the mounting groove, a proximity sensor is fixed to the side wall of the mounting groove, the proximity sensor is horizontally arranged, and a detection piece is fixed to the bottom of the material guide cylinder. When the material guide cylinder is reset, the proximity sensor can detect the detection piece.

[0023] By adopting the above technical solution, during material receiving, under the abutting action of the abutting plate, the linkage is pushed to rotate and drives the material guiding cylinder to rotate. At this time, the material guiding cylinder is in the material receiving state and the detection piece is separated from the proximity sensor. When the auxiliary shaft moves away and the material guiding cylinder resets under the action of the return spring, the detection piece rotates to be close to the proximity sensor. At this time, the proximity sensor can detect the detection piece, indicating that the working state is normal. If the proximity sensor does not detect the signal of the detection piece at this time, it means that the material guiding cylinder has not rotated to the original state. The proximity sensor sends a detection signal to the control system, and the control system controls the alarm. At this time, there may be sundries stuck between the material guiding cylinder and the driving motor, which needs to be cleaned and adjusted in time to avoid the risk brought by continuing processing in the state where the material guiding cylinder is stuck.

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

[0025] The auxiliary shaft mechanism can clamp the workpiece and move it. First, the auxiliary shaft mechanism drives the workpiece to be processed on the tool of the power device. At this time, the material guiding member is in an outwardly flipped state. When it is necessary to unload the material, the auxiliary shaft mechanism drives the workpiece to move towards the material guiding member. When the diameter of the workpiece is large, the auxiliary shaft mechanism abuts against the linkage and continues to push the linkage to rotate, thereby driving the upper end of the material guiding member to continue to rotate towards the auxiliary shaft mechanism, so that the feed port of the material guiding member and the auxiliary shaft mechanism can be exactly aligned, and at this time, the material guiding member does not collide with the tool close to the material guiding member, realizing the optimal utilization of space;

[0026] When the size of the workpiece to be processed changes, loosen the bolt and rotate the linkage. When the linkage is rotated downward, the amplitude of the linkage pushed by the auxiliary shaft mechanism decreases, so the amplitude of the material guiding cylinder swinging towards the auxiliary shaft mechanism decreases, thereby adapting to the workpiece unloading. When the linkage is rotated upward, the amplitude of the linkage pushed by the auxiliary shaft mechanism increases, so the amplitude of the material guiding cylinder swinging towards the auxiliary shaft mechanism increases, thereby adapting to the unloading of larger diameter workpieces.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Referring to Figure 1 and Figure 2 , a machine tool structure for optimizing the blanking space disclosed by the present invention includes a bed body 1 and a sub-spindle mechanism 2 provided on the bed body 1. The bed body 1 is further provided with a mounting seat 3 opposite to the sub-spindle mechanism 2. A power device 4 is provided on the mounting seat 3, and a plurality of cutting tools 5 are provided on the power device 4. A blanking mechanism 6 is provided at a position on one side of the bed body 1 where the sub-spindle mechanism 2 is located. The blanking mechanism 6 includes a guiding member 7 rotatably connected to the bed body 1 and a transmission mechanism 8 connected to the bed body 1 and located below the guiding member 7. The bottom end of the guiding member 7 is connected with a linkage member 9. The linkage member 9 intermittently abuts against the sub-spindle mechanism 2, and when the linkage member 9 abuts against the sub-spindle mechanism 2, the distance between the top end of the guiding member 7 and the nearest cutting tool 5 is greater than or equal to 0. The sub-spindle mechanism 2 can clamp and move the workpiece. First, the sub-spindle mechanism 2 drives the workpiece to be processed on the cutting tools 5 of the power device 4. At this time, the guiding member 7 is in an outwardly flipped state. When blanking is required, the sub-spindle mechanism 2 drives the workpiece to move towards the guiding member 7. When the diameter of the workpiece is relatively large, the sub-spindle mechanism 2 abuts against the linkage member 9 and continues to push the linkage member 9 to rotate, thereby driving the upper end of the guiding member 7 to continue to rotate towards the sub-spindle mechanism 2, so that the feeding port 11 of the guiding member 7 can be exactly aligned with the sub-spindle mechanism 2, and at this time, the guiding member 7 does not collide with the cutting tool 5 close to the guiding member 7, realizing the optimal utilization of space.

[0032] The guiding member 7 includes a guiding cylinder 10 whose bottom end is hinged to the bed body 1 through a rotating shaft. The guiding cylinder 10 is arranged in a tubular shape that penetrates up and down. The top of the guiding cylinder 10 is provided with a feeding port 11. The opening direction of the feeding port 11 is horizontal and faces the sub-spindle 19. The lower end opening of the guiding cylinder 10 is communicated with the transmission mechanism 8. After the sub-spindle mechanism 2 drives the workpiece to the feeding port 11, the sub-spindle mechanism 2 moves away, and the guiding member 7 flips outward again, so that the workpiece falls into the transmission mechanism 8 through the feeding port 11 and the guiding cylinder 10 and is driven and sent out by the transmission mechanism 8.

[0033] As Figure 1 and Figure 2 shown, the linkage member 9 is arranged in a rod shape. One end of the linkage member 9 is connected to the side wall of the guiding cylinder 10, and the other end extends towards the sub-spindle mechanism 2 and can abut against the sub-spindle mechanism 2. The bed body 1 is connected with a reset member 12 for resetting the guiding cylinder 10. When the sub-spindle mechanism 2 moves towards the linkage member 9 and abuts against the linkage member 9, it can push the linkage member 9 to rotate downward. Since the linkage member 9 is fixedly connected to the guiding cylinder 10, it can drive the guiding cylinder 10 to rotate towards the sub-spindle mechanism 2, so that the feeding port 11 is aligned with the workpiece of the sub-spindle mechanism 2, facilitating blanking.

[0034] As Figure 1 and Figure 2As shown, an installation block 13 is connected to the side wall of the material guiding cylinder 10. The end of the linkage member 9 is rotatably connected to the installation block 13. An arc-shaped adjustment groove 14 is provided in the installation block 13. The linkage member 9 is tightened to the adjustment groove 14 by bolts. The arc-shaped groove is centered on the rotation center of the linkage member 9. When the size of the workpiece to be processed changes, loosen the bolts and rotate the linkage member 9. When the linkage member 9 is rotated downward, the amplitude of the rotation of the linkage member 9 pushed by the secondary shaft mechanism 2 decreases, so that the amplitude of the swing of the material guiding cylinder 10 toward the secondary shaft mechanism 2 decreases, thereby adapting to the blanking of the workpiece. When the linkage member 9 is rotated upward, the amplitude of the rotation of the linkage member 9 pushed by the secondary shaft mechanism 2 increases, so that the amplitude of the swing of the material guiding cylinder 10 toward the secondary shaft mechanism 2 increases, thereby adapting to the blanking of workpieces with a larger diameter.

[0035] As Figure 1 and Figure 2 shown, the reset member 12 can be a spring. One end of the spring is connected to the side wall of the bed body 1, and the other end is connected to the top end of the outer wall of the material guiding cylinder 10 and applies a force for outward rotation to the material guiding cylinder 10. When the secondary shaft mechanism 2 abuts against the material guiding cylinder 10 and pushes the material guiding cylinder 10 to rotate toward the secondary shaft mechanism 2, the spring is in a stretched state. When the secondary shaft mechanism 2 moves away, under the reset action of the spring, the material guiding cylinder 10 can be pulled back to its original position, and the limit is realized through the power device 4 to prevent the material guiding cylinder 10 from turning outwards excessively.

[0036] As Figure 1 and Figure 2 shown, the power device 4 includes a power seat 15 fixedly connected to the mounting seat 3. Four tool holders 16 for mounting power heads are installed on one side of the power seat 15 facing the secondary shaft 19. A tool 5 is inserted into the tool holder 16. The power seat 15 is connected to a driving motor 17. The driving motor 17 is located on the side of the material guiding cylinder 10 away from the secondary shaft mechanism 2. One end of the tool holder 16 extends into the power seat 15 and is connected to a gear. The other end of the tool holder 16 extends out of the power seat 15 and is used for mounting the tool 5. The driving motor 17 drives the tool holder 16 through a gear structure and drives the tool 5 to rotate. Different styles of tools 5, such as drill bits, milling cutters, etc., can be inserted into the tool holder 16, so that the workpiece processing is more diversified and more adaptable.

[0037] As Figure 1 and Figure 2 shown, the secondary shaft mechanism 2 includes a base 18 slidably connected to the bed body 1 through a lead screw. Two sets of lead screws arranged perpendicular to each other drive the base 18 to move in the X-axis and Y-axis directions. A secondary shaft 19 is connected to the base 18. An abutting plate 21 is also provided on the base 18. The abutting plate 21 can abut against the linkage member 9 and push the linkage member 9 to rotate. The abutting plate 21 and the linkage member 9 are used in cooperation. Thus, when the base 18 moves, the abutting plate 21 moves relative to the linkage member 9 and pushes the linkage member 9 to rotate downward, thereby driving the material guiding cylinder 10 to rotate.

[0038] The transmission mechanism 8 includes a conveyor belt 20 disposed on the machine body 1. The feeding end of the conveyor belt 20 is located below the opening of the material guiding cylinder 10, and the discharging end of the conveyor belt 20 extends outside the machine. The processed workpieces slide down from the material guiding cylinder 10, fall onto the conveyor belt 20 and are sent outwards by the conveyor belt 20, realizing automatic feeding of the workpieces, making the blanking more convenient, labor-saving and more efficient.

[0039] As Figure 1 and Figure 2 shown, an installation groove is formed on the side of the machine body 1. The bottom end of the material guiding cylinder 10 is hinged to the inner wall of the installation groove. A proximity sensor 22 is fixed on the side wall of the installation groove. The proximity sensor 22 is horizontally arranged. A detection piece 23 is fixed at the bottom of the material guiding cylinder 10. When the material guiding cylinder 10 resets, the proximity sensor 22 can detect the detection piece 23. When receiving materials, under the abutting action of the abutting plate 21, the linkage 9 is pushed to rotate and drives the material guiding cylinder 10 to rotate. At this time, the material guiding cylinder 10 is in the state of receiving materials and the detection piece is separated from the proximity sensor 22. When the auxiliary shaft 19 moves away and the material guiding cylinder 10 resets under the action of the reset spring, the detection piece 23 rotates to be close to the proximity sensor 22. At this time, the proximity sensor 22 can detect the detection piece 23, indicating that the working state is normal. If the proximity sensor 22 does not detect the signal of the detection piece 23 at this time, it means that the material guiding cylinder 10 has not rotated to the original state. The proximity sensor 22 sends a detection signal to the control system, and the control system controls an alarm to remind the operator that there may be sundries stuck between the material guiding cylinder 10 and the driving motor 17, and it is necessary to clean and adjust in time, avoiding the risk brought by continuing processing in the stuck state of the material guiding cylinder 10.

[0040] The implementation principle of this embodiment is as follows: The auxiliary shaft 19 clamps the workpiece and processes it on the corresponding tool 5. When blanking is required, the base 18 moves to drive the workpiece to move towards the direction of the material guiding cylinder 10. At the same time, the abutting plate 21 abuts against the linkage 9 and pushes the linkage 9 to rotate downwards, thereby driving the upper end of the material guiding cylinder 10 to rotate towards the auxiliary shaft 19 until the feeding port 11 of the material guiding cylinder 10 is aligned with the auxiliary shaft 19. The workpiece on the auxiliary shaft 19 falls onto the conveyor belt 20 through the feeding port 11 and the material guiding cylinder 10, realizing blanking and sending out, and completing automatic blanking.

[0041] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
