Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and specifically relates to a feeding device for a multi-channel processing machine tool. Background Art

[0002] With the gradual development and progress of the processing industry, processing equipment and processing machine tools have now been gradually developed to have machine tools that can perform different processing operations with two or more channels. Existing processing is all mechanical processing, and mechanical processing is to process metal blank parts into the required shapes, including two aspects of dimensional accuracy and geometric accuracy. Therefore, mechanical processing has high requirements for accuracy. Existing equipment mostly uses the method of cooperating an automatic feeding device with a manipulator to complete the gradual transfer of workpieces, and the accuracy of the manipulator grasping the workpiece is crucial;

[0003] However, the feeding devices supporting existing processing machine tools still have the following defects during specific use:

[0004] ① First, when the manipulator clamps the workpiece from the feeding device, due to reasons such as the vibration generated during the operation of the machine tool and the low accuracy during the feeding of the feeding device, the workpiece deviates when it is sent by the feeding device to the preset grasping point of the manipulator, resulting in a large deviation in the clamping of the manipulator. Seriously, it will cause the manipulator to have an empty grasping phenomenon. If this phenomenon is not improved, it will greatly reduce the overall processing efficiency of the processing machine tool for workpieces;

[0005] ② In addition, for the hopper of the existing feeding device, when the feeding device is out of material, the manipulator lacks the function of automatic identification, resulting in the manipulator repeatedly having an empty grasping situation, thus causing unnecessary loss of production resources;

[0006] ③ At the same time, during the process of the manipulator grasping and moving the workpiece, since chips are generated during the processing of the workpiece, when the manipulator grasps the workpiece, the surface of the manipulator will inevitably be attached with chips. After the chips are attached to the manipulator, it will not only cause damage to the internal components of the manipulator, but also reduce the firmness of the manipulator's grasping.

[0007] Therefore, in view of this, the present invention proposes a feeding device for a multi-channel processing machine tool to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0008] To solve the above technical problems, the present invention provides a feeding device for a multi-channel processing machine tool to solve the corresponding technical problems raised in the above background art.

[0009] To achieve the above object, the technical solution adopted by the present invention is as follows: A feeding device for a multi-channel processing machine tool, including a feeding device, a system control unit is arranged inside the feeding device, the feeding device is composed of a vibrating disk and a conveyor belt, a centering and correcting positioning mechanism and a mechanical grasping auxiliary mechanism are arranged on the front side of the feeding device, and a base is installed at the bottom of the vibrating disk;

[0010] The centering and correcting positioning mechanism includes: a revolving door, a rotating wheel, a gear, a rack, a telescopic rod, a positioning clamp, a support table, a workbench, and a mounting seat. A revolving door is arranged on the front side of the conveyor belt. The lower end of the revolving door is fixedly connected to a rotating wheel. Notches are evenly arranged on the outer part of the rotating wheel. Gears are evenly meshed inside the rotating wheel. The upper halves of the gears are all meshed with racks. The outer ends of the racks are inserted into the outer notches of the rotating wheel. The inner ends of the racks are provided with support tables. A telescopic rod is fixedly connected above the racks. A positioning clamp is fixedly installed at the inner end of the telescopic rod. The upper surface of the support table is fixedly connected to a workbench. Centering grooves are evenly arranged on the surface of the workbench. The lower end of the revolving door is installed with a mounting seat.

[0011] Preferably in the present invention, the bottom surface of the base is parallel to the bottom surface of the vibrating disk, the table surface of the conveyor belt and the workbench are on the same horizontal plane, and the end of the conveyor belt close to the workbench is communicated with the workbench.

[0012] Preferably in the present invention, there are four gears meshed inside the rotating wheel, and the gears and the rotating wheel are symmetrically distributed.

[0013] Preferably in the present invention, the outer parts of the support tables are all provided with notches the same as those on the outer part of the rotating wheel, and the inner ends of the racks are inserted into the outer notches of the support tables.

[0014] Preferably in the present invention, the lower surface of the revolving door is rotatably connected to the upper surface of the mounting seat, and the revolving door is symmetrically structured on the upper surface of the mounting seat.

[0015] Preferably in the present invention, the telescopic rods are all located on the upper surface of the workbench, and the bottom of the workbench is slidably connected to the centering grooves on the surface of the workbench through an axis.

[0016] Preferably in the present invention, the mechanical grasping auxiliary mechanism includes: a moving column, a spring, a brush, and a sensor. Inclined arc grooves are penetrated through the inner walls of the revolving door. A moving column is arranged inside the revolving door. A ring is fixedly connected to the upper end of the moving column. Brushes are evenly arranged inside the ring at the upper end of the moving column. A sensor is installed on the lower surface of the moving column. A spring is arranged outside the revolving door.

[0017] Preferably in the present invention, the moving columns are symmetrically arranged around the center of the workbench, and both bottom sides of the moving columns are slidably connected to the inclined arc grooves formed in the inner wall of the revolving door through shafts.

[0018] Preferably in the present invention, four sensors are provided. The four sensors are evenly installed on the lower surface of the column body in the middle of the two rings of the moving column. The four sensors are electrically connected to the system control unit arranged inside the feeding device. When the sensors sense that the manipulator fails to grasp the material, a signal will be sent to the system control unit inside the feeding device, so as to stop the vibration of the vibrating disk and end the movement of the manipulator.

[0019] Compared with the prior art, the beneficial effects achieved by the technical solution of the present invention are as follows:

[0020] (1) When the positioning clamp is squeezed, the positioning clamp generates a force to move outward. The protruding part of the telescopic rod contracts towards the inside of the telescopic rod, thereby driving the positioning clamp to move outward, so as to adjust the distance of the positioning clamp, so as to adapt to workpieces of different sizes. Through the downward movement of the manipulator, the activity of the centering and correcting positioning mechanism is driven. Through the horizontal movement of the telescopic rod, the positioning clamp is driven to fix the four sides of the component, ensuring the position of the component and the accuracy of the manipulator clamping, preventing the deviation of the workpiece caused by machine vibration, and thus improving the processing accuracy of the workpiece;

[0021] (2) Through the identification function of the sensor, when there is no material entering the surface of the workbench, the sensor will send an electrical signal to the system control unit of the feeding system to stop the movement of the vibrating disk and the manipulator, prevent the manipulator from grasping empty, reduce unnecessary energy waste, and trigger an alarm to remind the staff;

[0022] (3) Through the up and down movement of the manipulator in the middle ring of the moving column, the manipulator contacts with the bristles, thereby removing the debris adhered to the surface of the manipulator, reducing the influence of the debris on the manipulator and the processing, and thus ensuring the stability of the manipulator and the accuracy of the component processing.

[0036] Embodiments of the present invention

[0037] Please refer to Figure 1 As shown, a feeding device for a multi-channel processing machine tool includes a feeding device 1. A system control unit is arranged inside the feeding device 1. The feeding device 1 is composed of a vibrating disk 11 and a conveyor belt 12. There is a centering and correcting positioning mechanism 2 and a mechanical grasping auxiliary mechanism 3 on the front side of the feeding device 1. The bottom of the vibrating disk 11 is provided with a base 13. The bottom surface of the base 13 is parallel to the bottom surface of the vibrating disk 11. The tabletop of the conveyor belt 12 and the workbench 28 are on the same horizontal plane. One end of the conveyor belt 12 close to the workbench 28 is connected to the workbench 28.

[0038] The centering and correcting positioning mechanism 2 includes: a revolving door 21, a rotating wheel 22, a gear 23, a rack 24, a telescopic rod 25, a positioning clamp 26, a support table 27, a workbench 28, and a mounting seat 29. A revolving door 21 is arranged on the front side of the conveyor belt 12. The lower end of the revolving door 21 is fixedly connected to a rotating wheel 22. The outer part of the rotating wheel 22 is evenly provided with notches. The inner part of the rotating wheel 22 is evenly meshed with gears 23. There are four gears 23 meshed inside the rotating wheel 22. The gears 23 and the rotating wheel 22 are symmetrically distributed. The upper half parts of the gears 23 are all meshed with racks 24. The outer ends of the racks 24 are inserted into the external notches of the rotating wheel 22. The inner ends of the racks 24 are provided with support tables 27. The outer parts of the support tables 27 are all provided with notches identical to those of the external part of the rotating wheel 22. The inner ends of the racks 24 are inserted into the external notches of the support tables 27. The upper parts of the racks 24 are fixedly connected to telescopic rods 25. The inner ends of the telescopic rods 25 are fixedly installed with positioning clamps 26. The upper surfaces of the support tables 27 are fixedly connected to workbenches 28. The surfaces of the workbenches 28 are evenly provided with centripetal grooves. The lower end of the revolving door 21 is provided with a mounting seat 29. The lower surface of the revolving door 21 is rotatably connected to the upper surface of the mounting seat 29. The revolving door 21 is symmetrically structured on the upper surface of the mounting seat 29.

[0039] Refer to Figure 4 , Figure 7 As shown in

[0040] The complete usage steps and working principles of the above embodiments are as follows:

[0041] Before use: Refer to Figure 6 , Figure 8 As shown, the bottom of the moving column 31 is at the highest point in the middle groove of the revolving door 21. At this time, it is the most original state of the equipment. Since the telescopic rod 25 is not squeezed, it is at the maximum moving distance at this time.

[0042] During use: The vibrating disk 11 automatically feeds materials upward. After being conveyed by the conveyor belt 12, it reaches the upper surface of the workbench 28. When the manipulator moves from the upper part of the moving column 31 to the middle position of the moving column 31, it grabs the workpiece downward. When the manipulator passes through the upper surface of the moving column 31, the manipulator presses the upper surface of the moving column 31, driving the moving column 31 to move downward. Since the middle groove of the rotating door 21 limits the shaft at the bottom of the moving column 31, and the lower surface of the rotating door 21 is rotatably connected to the upper surface of the mounting seat 29 through an internal bearing, the moving column 31 moves vertically downward, and at the same time, the rotating door 21 rotates clockwise. Since the rotating door 21 is fixedly connected to the rotating wheel 22, when the rotating door 21 rotates clockwise, the rotating wheel 22 also rotates clockwise. When the rotating wheel 22 rotates clockwise, since the lower half of the rotating wheel 22 meshes with the gear 23, the gear 23 starts to rotate clockwise. Also, since the upper half of the gear 23 meshes with the rack 24, when the gear 23 rotates clockwise and the inner end of the rack 24 is restricted in the notch of the support table 27, the rack 24 moves horizontally toward the middle direction. Since the upper surface of the rack 24 is fixedly connected to the telescopic rod 25, and the bottom of the telescopic rod 25 is slidably connected to the centripetal groove on the surface of the workbench 28 through a shaft, when the rack 24 moves horizontally inward, it drives the telescopic rod 25 to move horizontally inward. Since the telescopic rod 25 is fixedly connected to the positioning clamp 26, the positioning clamps 26 all move horizontally inward, thereby fixing the position of the workpiece, avoiding the situation of sliding displacement of the workpiece during clamping, which may cause the manipulator to grasp inaccurately, and ensuring that the manipulator correctly grasps the workpiece.

[0043] When the size of the workpiece is too large, once the positioning clamp 26 contacts the workpiece, the positioning clamp 26 is squeezed. Since the telescopic rod 25 and the positioning clamp 26 are fixedly connected and the telescopic rod 25 has a telescopic function, the protruding part of the telescopic rod 25 contracts inward into the telescopic rod 25, thereby driving the positioning clamp 26 to move outward, so as to adapt to workpieces of different sizes and expand the applicable range of the positioning clamp 26.

[0044] When the manipulator successfully picks up the workpiece, the spring 32 is in a compressed state at this time. When the manipulator moves upward, the manipulator no longer exerts pressure on the moving column 31, and then the rotating door 21 no longer rotates. However, at this time, the spring 32 is in a compressed state, and the spring 32 is fixedly connected to the rotating door 21. Therefore, under the action of the elastic rebound force of the spring, the rotating door 21 is urged to move counterclockwise. Since the rotating door 21 is fixedly connected to the rotating wheel 22, the rotating wheel 22 is also driven to move counterclockwise. Due to the meshing action between the rotating wheel 22 and the gear 23, the gear 23 also moves counterclockwise, thereby driving the rack 24 to move horizontally outward. Since the rack 24 is fixedly connected to the telescopic rod 25, the telescopic rod 25 will move along the outer direction of the groove inside the workbench 28. Since the positioning clamp 26 is fixedly connected to the telescopic rod 25, the positioning clamps 26 all move along the outer direction of the groove. When the rotating door 21 moves counterclockwise, since the bottom shaft of the moving column 31 is in the middle groove of the rotating door 21, the moving column 31 can only move vertically upward. When the spring 32 ends the compressed state, the components are restored to their original positions, so that the manipulator can perform the next grasping movement.

[0045] When the manipulator moves up and down through the middle ring of the moving column 31, the brush hairs 33 can clean the surface of the manipulator and the workpiece, preventing surface debris from reducing the firmness of the manipulator's grasping, thereby improving the machining accuracy of the workpiece and ensuring the accuracy of component machining.

[0046] When there is no material in the vibrating bowl 11, at this time, no material enters the workbench 28. The sensor 34 detects that no material enters, and then sends a signal to the system control unit inside the feeding device 1, thereby stopping the operation of the vibrating bowl 11 and the manipulator, preventing the manipulator from grasping empty, and triggering an alarm to remind the staff.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
