[0036] 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.

[0037] Please see Figure 1-4 This utility model provides a technical solution: a flipping tool for gearbox machining, comprising:

[0038] Workbench 1, with multiple support rods 2 on the top of the workbench 1, and a top plate 3 on the top of the multiple support rods 2;

[0039] A horizontal moving component is provided at the bottom of the top plate 3;

[0040] A pair of first movable plates 8 are movably mounted on a horizontal moving component, which can drive the pair of first movable plates 8 to move towards or away from each other.

[0041] A pair of vertical adjustment components are rotatably mounted on the opposite side walls of a pair of first moving plates 8. A second motor 9 is mounted on one of the first moving plates 8, and the second motor 9 can drive the corresponding set of vertical adjustment components to rotate.

[0042] Two pairs of fixing components are mounted on a pair of vertical adjustment components. Each pair of vertical adjustment components can move each pair of fixing components towards or away from each other. The two pairs of fixing components are used to fix the gearbox.

[0043] In this embodiment, there are four support rods 2, which are used to support the top plate 3. When the gearbox is set between two pairs of fixed components, the horizontal moving component can drive a pair of first moving plates 8 to move towards each other, so that a pair of vertical adjusting components are close to the gearbox. Each set of vertical adjusting components can cause a pair of fixed components set on it to move towards each other. Then, the two pairs of fixed components abut against the eight corners of the gearbox for fixation. During the processing, the second motor 9 is started to drive a set of vertical adjusting components to rotate. This set of vertical adjusting components drives the gearbox and another set of vertical adjusting components to rotate, thereby adjusting the circumferential position of the gearbox.

[0044] As one embodiment of this utility model, the horizontal moving component includes:

[0045] A pair of first fixing plates 4 are provided at the bottom of the top plate 3;

[0046] Four first limiting rods 5 are arranged between a pair of first fixed plates 4 and pass through a pair of first movable plates 8 and are slidably connected to the pair of first movable plates 8.

[0047] The first bidirectional lead screw 7 is rotatably mounted on a pair of first fixed plates 4, and a pair of first movable plates 8 are threadedly connected to the first bidirectional lead screw 7.

[0048] The first motor 6 is mounted on one of the first fixed plates 4, and the output shaft of the first motor 6 is connected to the first bidirectional lead screw 7.

[0049] In this embodiment, the first motor 6 is a servo motor or a stepper motor. When the first motor 6 is started, the output shaft of the first motor 6 drives the first bidirectional lead screw 7 to rotate. The first bidirectional lead screw 7 is mounted on a pair of first fixed plates 4 through a pair of bearings. When the first bidirectional lead screw 7 rotates, it drives a pair of threaded first moving plates 8 to move towards or away from each other. When the first moving plates 8 move, four first limit rods 5 can limit them, so that the first moving plates 8 are always in a vertical state.

[0050] As one embodiment of this utility model, each set of vertical adjustment components includes:

[0051] Ring 10 is disposed on the side wall of the first movable plate 8, and bearing 11 is disposed inside the ring 10;

[0052] Rotating plate 12 is mounted on the inner ring of bearing 11, and the output shaft of the second motor 9 is connected to rotating plate 12;

[0053] A pair of second fixing plates 13 are provided on the rotating plate 12, and four second limiting rods 14 are provided between the pair of second fixing plates 13.

[0054] A pair of second movable plates 15 are slidably mounted on four second limit rods 14;

[0055] The second bidirectional lead screw 16 is rotatably mounted on a pair of second fixed plates 13, and a pair of second movable plates 15 are threadedly connected to the second bidirectional lead screw 16. One of the second fixed plates 13 is provided with a shaft locking device for fixing the second bidirectional lead screw 16.

[0056] In this embodiment, a handwheel is provided at the end of the second bidirectional lead screw 16 extending outside the second fixed plate 13. When the operator rotates the second bidirectional lead screw 16, the handwheel is rotated for easy operation. When the operator rotates the handwheel and drives the second bidirectional lead screw 16 to rotate, the second bidirectional lead screw 16 drives a pair of second moving plates 15 to move towards or away from each other. Four second limiting rods 14 limit the second moving plates 15 to prevent them from deviating during movement. After the second moving plates 15 move to the specified position, the second bidirectional lead screw 16 is fixed by the first shaft locking device 17.

[0057] As one embodiment of this utility model, each set of fixing components includes:

[0058] The third bidirectional lead screw 18 has a sliding groove on the third movable plate, and the third bidirectional lead screw 18 is rotatably mounted in the sliding groove.

[0059] A pair of movable rods 19 are slidably disposed in the slide groove and threadedly connected to the third bidirectional lead screw 18. Each movable rod 19 has a locking block 20 at its end.

[0060] The second shaft locking device 21 is mounted on the second movable plate 15 and is used to fix the third bidirectional lead screw 18.

[0061] In this embodiment, a handwheel is provided at one end of the third bidirectional lead screw 18 extending outside the second moving plate 15. When the operator rotates the handwheel to rotate the third bidirectional lead screw 18, the third bidirectional lead screw 18 drives a pair of threaded moving rods 19 to move towards or away from each other. When the moving rods 19 move, they drive the locking block 20 to move. When the third bidirectional lead screw 18 moves to the specified position, it is fixed by the second shaft locking device 21.

[0062] As an embodiment of the present invention, a counterweight 22 is provided on one end of each pair of second fixing plates 13 away from the first shaft locking device 17.

[0063] In this embodiment, under the weight of the counterweight 22, the second fixing plate 13 on which the counterweight 22 is provided can be positioned below the second fixing plate 13 on which the first shaft locking device 17 is provided, so that when the gearbox is initially fixed, it is easy to align the locking block 20 with the end corner of the gearbox.

[0064] As an embodiment of the present invention, a cylinder 23 is provided at the bottom of the workbench 1 and between four pairs of locking blocks 20. The telescopic end of the cylinder 23 passes through the workbench 1 and a lifting plate 24 is provided at the end.

[0065] In this embodiment, when fixing the gearbox, the gearbox is placed on the lifting plate 24, and the gearbox is lifted to the specified height by the cylinder 23 before being fixed. There is no need for personnel to support or lift the gearbox, which is convenient for personnel to operate.

[0066] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0067] The working principle and usage process of this utility model are as follows: When in use, firstly, the personnel place the gearbox on the lifting plate 24, start the cylinder 23, the telescopic end of the cylinder 23 extends and drives the lifting plate 24 to move vertically upward, and the lifting plate 24 drives the gearbox to move vertically upward to the specified height and then stops.

[0068] Next, the operator screws each of the second bidirectional lead screws 16. When each of the second bidirectional lead screws 16 rotates, it drives a pair of threaded second moving plates 15 to move in opposite directions or back to back. When each of the second moving plates 15 moves, it drives the third bidirectional lead screw 18, a pair of moving rods 19, and a pair of locking blocks 20 to move. The operator then screws multiple third bidirectional lead screws 18. When the third bidirectional lead screw 18 rotates, it drives a pair of threaded moving rods 19 to move in opposite directions or back to back. The moving rods 19 drive the locking blocks 20 to move, so that the locking blocks 20 at the ends of the four pairs of moving rods 19 correspond to the positions of the eight end corners of the gearbox. After adjustment, the second bidirectional lead screw 16 is fixed by the first shaft locking device 17, and the third bidirectional lead screw is fixed by the second shaft locking device 21.

[0069] Next, the first motor 6 is started. The output shaft of the first motor 6 drives the connected first bidirectional lead screw 7 to rotate. The first bidirectional lead screw 7 drives a pair of threaded first moving plates 8 to move towards each other, thereby causing the eight locking blocks 20 to abut against the eight end corners of the gearbox to fix the gearbox.

[0070] Finally, the telescopic end of cylinder 23 retracts, and the lifting plate 24 disengages from the bottom of the gearbox. Personnel then use drilling or grinding tools to process the gearbox. If the position of the gearbox needs to be adjusted during processing, the second motor 9 is started. The second motor 9 is a stepper motor or a servo motor. The second motor 9 drives the connected rotating plate 12 to rotate, and the rotating plate 12 drives the two pairs of locking blocks 20 on the same side to rotate. These two pairs of locking blocks 20 drive the gearbox to rotate, and the gear drives the two pairs of locking blocks 20 on the other side to rotate. When the gearbox reaches the specified position, the second motor 9 stops rotating. Since the second motor 9 has a self-locking function, it can keep the position of the gearbox so that personnel can continue processing.

[0071] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
