Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a feeding device for flipping workpieces. Background Technology

[0002] In automated mechanical production, taking nut processing as an example, after the blank is fed by a vibratory feeder, it is arranged and conveyed by a linear feeder. At this time, the nut blank is usually placed in a horizontal state, and its axis is perpendicular to the feeding plane. Existing feeding devices typically only have the ability to perform linear motion in the horizontal and vertical directions. For example, an automatic valve core sealing ring fitting device disclosed in application number CN202121503178.X has a clamping device including a clamping part and a driving part that drives the clamping part to move up and down and back and forth. The clamping jaws on the clamping part clamp the sealing ring on the second linear feeder and move it above the first feeder to fit the sealing ring onto the valve core. Another example is an automatic hexagonal through-hole screw processing machine disclosed in application number CN202221877467.0. Its feeding device for moving hexagonal screws from the material distribution groove to the clamping groove includes a feeding seat located on one side of the turntable device; a translation seat that slides on the feeding seat and moves horizontally; a translation cylinder that is fixed on the feeding seat and connected to the translation seat; a lifting seat that slides on the translation seat and moves vertically; a lifting cylinder that is installed on the translation seat and connected to the lifting seat; and a clamping jaw cylinder that is fixed on the lifting seat for gripping the hexagonal screws.

[0003] Therefore, it is evident that the existing grippers in the aforementioned patent, which grasp horizontally positioned workpieces from the linear feeder, maintain their horizontal orientation after being transferred to the fixture. Workpieces in this state are only suitable for machining with drilling, tapping, and other cutting tools positioned longitudinally on the worktable and fed vertically, limiting their application scenarios. When the drilling, tapping, and other cutting tools on the worktable are fed horizontally, the workpieces, held and transferred horizontally within the fixture by the existing grippers, cannot be machined because their axis is perpendicular to the tool's feed direction. Therefore, the existing feeding device needs improvement. During the feeding process, the spatial orientation of the workpiece should be transformed; that is, the horizontally positioned workpiece on the linear feeder should be actively flipped to a vertical position to accommodate the machining requirements of horizontally fed cutting tools, thereby improving the applicability and flexibility of the automated production line. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problems in the prior art where the feeding device only has the ability to move linearly in the horizontal and vertical directions, and the workpieces it transfers are only suitable for processing by drilling, tapping tools, etc. that are fed in the vertical direction. The invention provides a method that actively flips the horizontal workpiece on the linear feeder during the feeding process, so that it changes to a vertical state, in order to adapt to the processing requirements of horizontally fed processing tools.

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding device, including a vibratory feeder mounted on a workbench and a linear feeder mounted at the discharge port of the vibratory feeder. A clamping mechanism is mounted on the workbench via a fixed frame. The clamping mechanism includes a jaw located above the linear feeder and a first driving mechanism for driving the jaw to rotate 0~90°. A bearing seat is connected to the output shaft of the first driving mechanism. A rotating shaft is rotatably mounted inside the bearing seat. A first mounting plate for mounting the jaw is provided at one end of the rotating shaft. A roller is connected to the other end of the rotating shaft via a second mounting plate. An "L"-shaped guide groove is provided on the fixed frame, and the roller slides in cooperation with the guide groove.

[0006] As a further improvement of this utility model, the aforementioned fixing frame includes a base plate arranged in the horizontal direction and a first side plate and a second side plate respectively arranged in the longitudinal direction on the base plate, wherein the base plate, the first side plate, and the second side plate are perpendicular to each other.

[0007] As a further improvement of this utility model, the first drive mechanism described above is mounted on the first side plate, and the output shaft of the first drive mechanism moves along the feeding direction of the linear feeder.

[0008] As a further improvement of this utility model, the axial direction of the aforementioned rotating shaft is perpendicular to the movement direction of the output shaft of the first drive mechanism.

[0009] As a further improvement of this utility model, the aforementioned "L"-shaped guide groove is formed on the second side plate.

[0010] As a further improvement of this utility model, a slide rail is provided on the base plate along the movement direction of the output shaft of the first drive mechanism, a slider is slidably arranged on the slide rail, and the bearing seat is mounted on the slider.

[0011] As a further improvement of this utility model, the first mounting plate is provided with a second driving mechanism for driving the gripper to move in a straight line and a third driving mechanism for driving the gripper to clamp or release the workpiece.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the sliding cooperation of the "L"-shaped guide groove and the roller, converts the drive of the first drive mechanism for the horizontal linear motion of the bearing seat into the rotation of the gripper between 0 and 90°, forcing the gripper's posture to change from vertical to horizontal, so that the nut blank it holds changes from a horizontally placed state on the linear feeder to a vertical state, and maintains the vertical state to enter the fixture for positioning and clamping, so as to adapt to the processing requirements of horizontal feed machining tools; 2. In this utility model The clamping mechanism can realize the translation of the jaws on the slide rail and the rotation between 0 and 90° by setting a single first drive mechanism. It has a simple structure, low manufacturing and maintenance costs, and high economic benefits. 3. In this utility model, by removing the second mounting plate and rollers, the workpiece clamped and transferred by the jaws in the clamping mechanism can be kept in a horizontal state and enter the fixture to complete the positioning and clamping, so as to deal with the processing of drilling, tapping and other tools fed in the vertical direction. This utility model can flexibly adapt to tool processing devices with different feed directions. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Rather, the present utility model covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present utility model as defined in the claims.

[0019] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0020] like Figures 1 to 4 The feeding device shown includes a vibratory feeder 2 mounted on a workbench 1 for initial feeding of nut blanks, and a linear feeder 3 mounted at the discharge port of the vibratory feeder 2 for arranging the nut blanks and sequentially conveying them to the gripping position. A clamping mechanism 5 is mounted on the workbench 1 via a fixed frame 4. In this embodiment, the fixed frame 4 includes a base plate 14 arranged horizontally and a first side plate 15 and a second side plate 16 respectively mounted longitudinally on the base plate 14. The base plate 14, the first side plate 15, and the second side plate 16 are perpendicular to each other.

[0021] like Figures 2 to 4 As shown, the clamping mechanism 5 includes a gripper 6 located above the linear feeder 3 and a first drive mechanism 7 for driving the gripper 6 to rotate 0~90°. In this embodiment, the first drive mechanism 7 can be configured as a servo motor or a cylinder, and its housing is mounted on the first side plate 15 of the fixed frame 4. Its output shaft moves along the feeding direction of the linear feeder 3. A slide rail 17 is provided on the base plate 14 of the fixed frame 4 along the movement direction of the output shaft of the first drive mechanism 7. A slider 18 is slidably mounted on the slide rail 17. A bearing seat 8 is connected to the output shaft of the first drive mechanism 7, and the bearing seat 8 is mounted on the slider 18. The sliding cooperation between the slider 18 and the slide rail 17 ensures the accuracy of the horizontal movement of the bearing seat 8.

[0022] A rotating shaft 9 is rotatably mounted inside the bearing housing 8. The axis of the rotating shaft 9 is perpendicular to the direction of movement of the output shaft of the first drive mechanism 7. One end of the rotating shaft 9 is provided with a first mounting plate 10 for mounting the gripper 6. In this embodiment, the first mounting plate 10 is provided with a second drive mechanism 19 for driving the gripper 6 to move in a straight line. The second drive mechanism 19 can be configured as a servo motor or a cylinder to adjust the distance between the gripper 6 and the linear feeder 3 and between the gripper 6 and the fixture. The output shaft of the second drive mechanism 19 is connected to a third drive mechanism 20 for driving the gripper 6 to clamp or release the workpiece. The third drive mechanism can be configured as a finger cylinder. The gripper 6 is connected to the output shaft of the third drive mechanism 20. The other end of the rotating shaft 9 is connected to a roller 12 through a second mounting plate 11. The second side plate 16 of the fixing frame 4 is provided with an "L"-shaped guide groove 13, and the roller 12 slides in cooperation with the guide groove 13.

[0023] When the clamping mechanism 5 is in its initial state, the gripper 6 is in a vertically downward posture. Under the combined drive of the second drive mechanism 19 and the third drive mechanism 20, the gripper 6 moves a linear distance along the longitudinal direction to clamp the nut blank located on the linear feeder 3 and completely detach the nut blank from the linear feeder 3. Then, the first drive mechanism 7 starts, and its output shaft pushes the bearing seat 8 to move horizontally towards the clamp. During this process, the roller 12 on the rotating shaft 9, under the forced guidance of the "L"-shaped guide groove 13, slides from the vertical side to the horizontal side to complete the change of motion trajectory, forcing the gripper 6 to rotate 90° around the axis of the rotating shaft 9, changing its posture from vertical to horizontal. The nut blank is changed from being placed horizontally on the linear feeder 3 to being vertically inserted into the fixture for positioning and clamping, so as to facilitate subsequent drilling, tapping and other processing operations. After the clamping mechanism 5 completes the feeding of the nut blank, the second drive mechanism 19 and the third drive mechanism 20 work together to make the jaws 6 release the nut blank and move horizontally in a straight line a distance away from the fixture. Then, the first drive mechanism 7 starts, and its output shaft pulls the bearing seat 8 to move horizontally away from the fixture. During this process, the roller is once again forced to rotate 90° in the opposite direction under the forced guidance of the "L"-shaped guide groove 13, returning to the initial vertical downward posture, preparing for the next clamping of the nut blank.

[0024] When the drilling, tapping and other cutting tools on the worktable are fed in a vertical direction, the second mounting plate 11 and roller 12 on the clamping mechanism 5 can be removed so that the nut blank held and transferred by the jaws 6 is kept in a horizontal state and enters the fixture to complete the positioning and clamping. This is to cope with the processing of drilling, tapping and other cutting tools that are fed in a vertical direction, so that this utility model can flexibly adapt to cutting tool processing devices with different feed directions.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
