[0002] In the field of mechanical manufacturing, gears are important transmission components, and their processing accuracy and efficiency have a vital impact on the performance of the entire mechanical system. During the gear processing process, the fixture serves as a bridge connecting the machine tool and the workpiece, and its selection and use directly affect the gear processing quality and production efficiency. However, in the existing technology, there are some significant technical challenges and limitations in the fixture conversion device for gear processing.

[0003] The authorization announcement number in the prior art is: CN219967589U, and the name is a conversion device for turning of a large boring and milling machine. The patent is mainly composed of key components such as a chip suction box, a connecting plate, a connecting box, a servo motor and a transmission rod. The transmission rod is driven by the servo motor, which in turn drives the gear system (including the first gear and the second gear) and the driven rod to rotate, thereby realizing the clamping and rotation conversion functions of workpieces of different sizes. This design allows the workpiece to be processed in all directions during the processing. In addition, the device is also equipped with a chip suction box for collecting waste chips generated during the processing process, thereby improving the cleanliness of the working environment. The entire device embodies the characteristics of high efficiency, flexibility and environmental protection.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a fixture conversion device for gear processing, including a lathe body 1, a cavity is opened inside the lathe body 1, a fixing plate 3 is fixedly connected inside the cavity, a guide rail 4 is fixedly connected between the fixing plate 3 and the inner wall of the cavity, a control panel 2 is installed on the lathe body 1, a driven gear 12 is rotatably installed inside the lathe body 1, and a turntable 14 is fixedly connected to one side of the driven gear 12. Through the arrangement of structures such as a rotating sleeve 9 and a turntable 14, the rotation of the turntable 14 can be achieved through the meshing of the driving gear 16 and the driven gear 12 during use. When the turntable 14 rotates, the two rotating sleeves 9 can drive different fixtures to switch. After switching, the connection with the drive motor 5 is achieved through the arrangement of the clamping block 8, so that it starts to rotate, thereby achieving a more automated fixture conversion as a whole.

[0029] like Figure 1 to Figure 6 As shown, two symmetrically arranged through holes are provided inside the turntable 14 and the driven gear 12, and a rotating sleeve 9 is rotatably installed inside the two through holes, one side of one rotating sleeve 9 is fixedly connected to a clamp 10, and one side of the other rotating sleeve 9 is fixedly connected to a clamp 2 11, and both the clamp 10 and the clamp 2 11 are fixedly connected to an indicator rod 15.

[0030] like Figure 1 to Figure 6 As shown, a driving motor 18 is installed on one side of the lathe body 1, and the output end of the driving motor 18 is fixedly connected to a coaxially arranged rotating rod 17 through a coupling. The rotating rod 17 is rotatably installed inside the lathe body 1, and one end of the rotating rod 17 is fixedly connected to a driving gear 16, which is meshed with the driven gear 12.

[0031] like Figure 1 to Figure 6 As shown, a driving motor 5 is installed on one side of the lathe body 1, and the output end of the driving motor 5 is fixedly connected to a coaxially arranged connecting rod 6 through a coupling. An electric control cylinder 7 is installed at one end of the connecting rod 6, and a clamping block 8 is fixedly connected to the telescopic end of the electric control cylinder 7.

[0032] like Figure 1 to Figure 6 As shown, the two rotating sleeves 9 are provided with a card slot inside, and the card slot and the card block 8 have the same shape and size, and the card block 8 matches the card slot.

[0033] In this embodiment, two types of clamps are used for conversion during use. When in use, the control panel 2 is used to start the electric cylinder 7, thereby driving the clamping block 8 to move in the horizontal direction, and the clamping block 8 is inserted into the interior of the card slot. The connection between the rotating sleeve 9 and the connecting rod 6 is achieved through the cooperation between the two. After the connection is made, the driving motor 1 5 is started to realize the rotation of a single clamp. When the clamp needs to be converted, the electric cylinder 7 needs to be controlled to retract the clamping block 8 from the interior of the card slot. At this time, the connection between the clamp and the driving motor 1 5 is lost, and the driving motor 2 18 is started again to drive the rotating rod 17 to rotate, and the rotating rod 17 drives the driving gear 16 to rotate. Through the driving gear 16 and the driven gear 12 The engagement can realize the rotation of the turntable 14, and the two clamp positions can be switched during the rotation. The whole can be rotated 180° each time. This part can be realized through the program set in the control panel 2. After the conversion, the block 8 can be inserted into the inside of the card slot in the above manner and the rotation of the clamp can be realized by driving the motor 5. It should be noted that in order to ensure that the block 8 and the card slot can be aligned every time, an indicator rod 15 is provided on one side of the clamp. The position of the indicator rod 15 can be adjusted by manually rotating the turntable 14. When the indicator rod 15 is in a horizontal position, the block 8 and the card slot can be roughly corresponding. This part does not limit the type of clamp, and a traditional three-jaw chuck can be used.

[0034] Example 2

[0035] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a straight groove is opened inside the fixed plate 3, and a reciprocating screw 20 is rotatably installed inside the straight groove. One end of the reciprocating screw 20 extends out of the inside of the lathe body 1 and the fixed plate 3. Through the arrangement of the reciprocating screw 20 and the jet head group 22, after the fixture is converted, the replaced fixture can be jet cleaned by the jet head group 22, and the reciprocating movement of the jet head group 22 can be realized by the rotation of the reciprocating screw 20, thereby improving the cleaning effect of the fixture by the reciprocating cleaning method.

[0036] like Figure 1 to Figure 6 As shown, a drive motor 3 19 is installed on one side of the lathe body 1, and the drive motor 3 19 is fixedly connected to the extended end of the reciprocating screw 20 through a coupling. The outside of the reciprocating screw 20 is assembled with a movable plate 21 through a ball nut, and a limiting groove is opened on one side of the fixed plate 3, and the movable plate 21 is slidably connected to the inside of the limiting groove.

[0037] like Figure 1 to Figure 6 As shown, a nozzle group 22 is installed on the movable plate 21, and an air intake hose 13 is connected to the nozzle group 22. The air intake hose 13 passes through the interior of the lathe body 1, and the air intake hose 13 is connected to the air supply device.

[0038] In this embodiment, after each clamp conversion, since the previous clamps have just been used, there will be a large amount of impurities on their surfaces, and the processing of the gears will produce a large amount of iron filings and attached oil stains. After the conversion, the used clamp will be located on one side of the fixed plate 3. At this time, the drive motor 3 19 is started to realize the rotation of the reciprocating screw 20, which drives the movable plate 21 to reciprocate along the direction of the thread during rotation, and at the same time drives the jet head group 22. The jet head group 22 is connected to the air supply equipment through the air intake hose 13, and ventilation can be achieved when the internal valve is opened through the control panel 2. This part belongs to the prior art and will not be elaborated on again. The impurities on the surface of the clamp can be completely removed by the reciprocating jet cleaning method of the jet head group 22 to ensure the accuracy of next use.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
