Description
Technical Field
[0001] This utility model belongs to the field of machining, specifically a workpiece flipping device. Background Technology
[0002] During assembly, the workpiece needs to be rotated 90° and lowered. Currently, the traditional method involves two people rotating the workpiece, which is cumbersome, difficult to handle due to the workpiece's weight, and poses safety risks. Therefore, this invention designs a workpiece rotating device that can semi-automatically rotate the workpiece 90° and lower its height. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a workpiece flipping device that can semi-automatically flip and reduce the height of the workpiece, and is easy to operate.
[0004] The technical problem solved by this utility model is achieved through the following technical solution:
[0005] A workpiece flipping device includes a support frame, a desktop, an arc-shaped rack and pinion track, a motor, a drive gear, an upper limit pin mechanism, a lower limit pin mechanism, an upper position detection sensor, and a lower position detection sensor.
[0006] The bottom side of one side of the desktop panel is hinged to the support frame via lugs and a pivot. The motor is installed on the bottom side of the other side of the desktop panel. The output shaft of the motor is connected to a drive gear. An arc-shaped rack and pinion track is provided on the support frame, and the center of the arc of the rack and pinion track is the axis of the pivot. The drive gear meshes with the arc-shaped rack and pinion track.
[0007] An initial workpiece placement area is provided on the desktop, and a vertical baffle is provided on the outside of the initial workpiece placement area on the desktop.
[0008] An upper position detection sensor and a lower position detection sensor are installed on the support frame. An upper limit pin mechanism and a lower limit pin mechanism are installed on the right side plate of the support frame. A pin hole is provided on the desktop plate.
[0009] In the above technical solution, a side plate is provided on the side of the support frame, and the arc-shaped rack and pinion track is provided on the left side plate of the support frame.
[0010] In the above technical solution, the top of the baffle is provided with a top baffle section that bends toward the initial placement area of the workpiece, and a reinforcing rib is also provided on the back of the baffle.
[0011] In the above technical solution, a workpiece positioning block is provided in the initial workpiece placement area of the desktop board. When placing the workpiece, one side of the workpiece is placed against the workpiece positioning block so that the workpiece reaches the required designated placement position.
[0012] In the above technical solution, both the upper position detection sensor and the lower position detection sensor are proximity sensors. The upper position detection sensor is used to detect whether the desktop is in a horizontal state, and the lower position detection sensor is used to detect whether the desktop is in a vertical state (i.e., whether the desktop has reached the set flip position).
[0013] In the above technical solution, the upper limit pin mechanism and the lower limit pin mechanism have the same structure, both including a cylinder and a pin connected to the cylinder's actuating end. The cylinder drives the pin to actuate, so that the pin is inserted into the pin hole of the desktop panel, thereby locking the position of the desktop panel.
[0014] In the above technical solution, a base is provided on the bottom surface of the desktop panel near the right side panel, and the base is provided with pin holes corresponding to the pins.
[0015] In the above technical solution, feet are set at the four corners of the bottom of the support frame. The feet are connected to the support frame by vertical bolts. The height and level of the support frame can be adjusted by rotating the feet. By adjusting the height, it can adapt to the height position of the workpiece after it is flipped, and is used to adapt to the height of the subsequent handling mechanism.
[0016] The advantages and beneficial effects of this utility model are as follows:
[0017] This invention utilizes a motor to rotate a tabletop along an arc-shaped rack and pinion track, enabling semi-automatic workpiece rotation and height reduction with convenient operation. It incorporates an upper limit pin mechanism, a lower limit pin mechanism, an upper position detection sensor, and a lower position detection sensor. During operation, when the upper position detection sensor detects that the tabletop has reached a horizontal position, the motor stops, and the cylinder of the upper limit pin mechanism actuates, inserting its pin into the pin hole of the tabletop, thus stably locking the tabletop in a horizontal position. Conversely, when the lower position detection sensor detects that the tabletop has reached a vertical position, the motor stops, and the cylinder of the lower limit pin mechanism actuates, inserting its pin into the pin hole of the tabletop, thus stably locking the tabletop in a vertical position.

[0022] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.
[0023] A workpiece flipping device includes a support frame 1, a desktop plate 2, an arc-shaped rack and pinion track 3, a motor 4, a drive gear 5, an upper limit pin mechanism 61, a lower limit pin mechanism 62, an upper position detection sensor, and a lower position detection sensor.
[0024] See appendix Figure 3 The bottom side of the desktop panel 2 is hinged to the support frame 1 via lugs 21 and pivots 22 (there are two sets of lugs 21 and pivots 22, see appendix). Figure 2 The motor 4 is installed on the bottom surface of the other side of the desktop panel 2. The output shaft of the motor 4 is connected to the drive gear 5. An arc-shaped rack and pinion track 3 is set on the support frame 1, and the center of the arc of the arc-shaped rack and pinion track 3 is the axis of the rotating shaft 22. The drive gear 5 meshes with the arc-shaped rack and pinion track 3. When the motor 4 drives the drive gear 5 to rotate, the motor 4 drives the desktop panel 2 to rotate around the rotating shaft 22, thereby realizing the flipping. Furthermore, a side plate is provided on the side of the support frame 1, and the arc-shaped rack and pinion track 3 is set on the left side plate of the support frame 1.
[0025] A workpiece initial placement area is provided on the desktop 2 for placing the workpiece in its initial state. A vertical baffle 23 is provided on the outside of the workpiece initial placement area on the desktop 2 to support the workpiece after it has been rotated 90°. Furthermore, the top of the baffle 23 is provided with a top baffle section 231 that bends towards the workpiece initial placement area to prevent the workpiece from falling off the baffle 23 after being rotated 90°. A reinforcing rib 232 is also provided on the back of the baffle 23.
[0026] Furthermore, a workpiece positioning block 24 is provided in the initial workpiece placement area of the desktop 2 to position the workpiece in its flat state before it is flipped. When placing the workpiece, one side of the workpiece is placed against the workpiece positioning block 24 to make the workpiece reach the required designated placement position.
[0027] An upper position detection sensor and a lower position detection sensor are also provided on the support frame 1. Preferably, both the upper position detection sensor and the lower position detection sensor are proximity sensors and are set on the right side plate 12 of the support frame 1. The upper position detection sensor is used to detect whether the desktop 2 is in a horizontal state, and the lower position detection sensor is used to detect whether the desktop 2 is in a vertical state (i.e., to detect whether the desktop has reached the set flip position).
[0028] An upper limiting pin mechanism 61 and a lower limiting pin mechanism 62 are provided on the right side plate 12 of the support frame 1. The upper limiting pin mechanism 61 and the lower limiting pin mechanism 62 have the same structure, both including a cylinder and a pin connected to the cylinder's actuating end. The cylinder drives the pin to actuate, so that the pin is inserted into the pin hole of the desktop plate 2, thereby locking the position of the desktop plate 2. Specifically, a base 25 (see Appendix) is provided on the bottom surface of the desktop plate 2 near the right side plate 1. Figure 2 The base 25 has pin holes corresponding to the pins. During operation, when the upper position detection sensor detects that the desktop 2 has reached a horizontal state, the motor stops, and the cylinder of the upper limit pin mechanism 61 actuates, inserting its pin into the pin hole of the desktop 2, thereby stably locking the desktop 2 in a horizontal state; when the lower position detection sensor detects that the desktop 2 has reached a vertical state, the motor stops, and the cylinder of the lower limit pin mechanism 62 actuates, inserting its pin into the pin hole of the desktop 2, thereby stably locking the desktop 2 in a vertical state.
[0029] For further details, please see the appendix. Figure 2 Foot 7 is installed at the four corners of the bottom of the support frame 1. The foot 7 is connected to the support frame 1 by vertical bolts 71. The height and level of the support frame 1 can be adjusted by rotating the foot 7. By adjusting the height, it can adapt to the height position of the workpiece after it is flipped, and is used to adapt to the height of the subsequent handling mechanism.
[0030] The working process of the workpiece flipping device of this utility model is as follows:
[0031] Place the workpiece in the initial placement area of the desktop 2, and move the workpiece to the designated position of the workpiece positioning block 22, so that the side of the workpiece rests against the baffle 23. Then press the start button. The cylinder of the upper limit pin mechanism 61 moves to retract the pin, and the motor drives the gear to rotate forward, causing the desktop 2 to rotate downward. When the lower position detection sensor detects that the desktop 2 has reached the vertical state, the motor stops, and the cylinder of the lower limit pin mechanism 62 moves to insert its pin into the pin hole of the desktop 2, thereby locking the desktop 2 stably in the vertical state. Then, use a crane or other transportation method to remove the workpiece.
[0032] After the workpiece is removed, the motor return button is pressed. The cylinder of the lower limit pin mechanism 62 is activated, causing the pin to retract. The motor drives the gear to rotate in the opposite direction, causing the desktop plate 2 to rotate upward. When the upper position detection sensor detects that the desktop plate 2 has reached a horizontal state, the motor stops, and the cylinder of the upper limit pin mechanism 61 is activated, inserting its pin into the pin hole of the desktop plate 2, thereby stably locking the desktop plate 2 in a horizontal state, thus completing one work cycle.
[0033] The above description of the technical solution of this utility model is exemplary. It should be noted that, without departing from the core of this technical solution, any simple modifications, alterations, or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of this patent.
