By using the clamping device, rapid clamping and replacement of the gear workpiece can be realized, which greatly shortens the processing preparation time and improves production efficiency. In the processing of transmission gears, safety is an important link that cannot be ignored. The clamping device should ensure the stable fixation of the workpiece to prevent safety accidents caused by accidental movement of the workpiece. In summary, the clamping device plays a crucial role in the processing of transmission gears. It not only ensures the stable fixation of the workpiece and processing accuracy, but also improves processing efficiency and safety. With the continuous development of technology, the clamping device will become more intelligent and multifunctional, providing a more reliable solution for the processing of transmission gears.

[0003] Traditional clamping devices for processing transmission gears have deficiencies in use. One is that they cannot realize rapid clamping and release of gear workpieces; the other is that they cannot realize automatic loading and unloading of gear workpieces. Therefore, it is necessary to optimize and improve traditional clamping devices for processing transmission gears. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above problems existing in the traditional technology and provide a clamping device for processing transmission gears.

[0005] To achieve the above technical purposes and reach the above technical effects, the utility model is realized through the following technical solutions:

[0006] A clamping device for processing transmission gears includes a horizontal sliding table, a storage bin, a horizontal push rod, a push block, a lifting push rod and a clamp. Above one end of the horizontal sliding table, there is a storage bin for storing gear workpieces. A material pushing area is formed between the bottom end of the storage bin and the horizontal sliding table. A horizontal push rod is installed outside the material pushing area, and a push block is installed at the movable end of the horizontal push rod. The clamp is installed at the top end of the lifting push rod;

[0007] Convex teeth are provided on the outer side of the gear workpiece, and a shaft hole with a keyway is opened inside the gear workpiece;

[0008] The clamping device includes a housing, a forward and reverse motor, a rotating shaft, a driving gear, and a driven pressing plate. A forward and reverse motor is installed inside the housing. The output end of the forward and reverse motor is connected to the rotating shaft through a coupling. Two driving gears are fixed on the outer side of the rotating shaft. On both sides of each driving gear, driving tooth blocks penetrating the housing are arranged side by side. Tooth grooves matching the corresponding driving gears are formed inside the driving tooth blocks.

[0009] Further, in the above-mentioned clamping device for machining transmission gear, a storage area is provided inside the storage bin, and the cross-sectional shape of the storage area matches the shape of the gear workpiece.

[0010] Further, in the above-mentioned clamping device for machining transmission gear, an arc surface facilitating the cooperation with the gear workpiece is provided on the outer side of the pushing block.

[0011] Further, in the above-mentioned clamping device for machining transmission gear, a horizontal sliding groove is formed at the upper end of the horizontal sliding table. An activity perforation is formed above the lifting push rod in the horizontal sliding groove. Convex key through grooves are formed at the front and rear ends of the activity perforation. Activity grooves facilitating the horizontal displacement of the driven pressing plate are formed at the left and right ends of the activity perforation.

[0012] Further, in the above-mentioned clamping device for machining transmission gear, the bottom end of the pushing block is slidably restricted in the horizontal sliding groove, and the width value of the horizontal sliding groove matches the maximum outer diameter value of the gear workpiece.

[0013] Further, in the above-mentioned clamping device for machining transmission gear, the housing is formed by fixing a first housing and a second housing through fastening bolts. An axial installation groove for installing the forward and reverse motor, the rotating shaft, and the driving gear is jointly formed inside the first housing and the second housing. Two guiding sliding grooves facilitating the sliding of the driven pressing plate along the length direction of the horizontal sliding table are respectively formed on the first housing and the second housing.

[0014] Further, in the above-mentioned clamping device for machining transmission gear, the distance value between the two juxtaposed guiding sliding grooves matches the thickness value of the gear workpiece.

[0015] Further, in the above-mentioned clamping device for machining transmission gear, the cross-section of the driven pressing plate is a T-shaped structure with a wider outer part and a narrower inner part.

[0016] The beneficial effects of the present utility model are:

[0017] The structure of the utility model is reasonably designed. It mainly consists of a horizontal sliding table, a storage bin, a horizontal push rod, a push block, a lifting push rod and a clamp. The storage bin is used to deliver gear workpieces to the horizontal sliding table one by one. The horizontal push rod and the push block are used to transfer the gear workpiece above the clamp. The clamp is driven by the lifting push rod to move upward from below the horizontal sliding table until it passes through the gear workpiece. Then, the forward and reverse motor in the clamp operates, and the driving gear rotates with the rotating shaft and drives the driven pressure plates on both sides to extend from the shell of the clamp. The two groups of extended driven pressure plates can reliably clamp the gear workpiece. The lifting push rod can be used to drive the gear workpiece to adjust the height position according to requirements. When the machining operations such as grinding of the gear workpiece are completed, it is reset. The reverse motor reverses, so that the driven pressure plates are retracted into the shell, and then the lifting push rod drives the clamp to return to the position below the horizontal sliding table again. At this time, the processed gear workpiece is in an unlocked state, and it can be transferred by equipment such as a suction manipulator; repeating the above steps can realize the rapid clamping and release of the gear workpiece and automatic loading and unloading, which is beneficial to industrial production.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Brief Description of the Drawings

[0034] In this embodiment, a storage area is provided inside the storage bin 2, and the cross-sectional shape of the storage area matches the shape of the gear workpiece 7.

[0035] In this embodiment, an arc surface facilitating the cooperation with the gear workpiece 7 is provided on the outer side of the push block 4.

[0036] In this embodiment, a horizontal chute 101 is opened at the upper end of the horizontal slide 1. An activity perforation 102 is opened above the lifting push rod 5 in the horizontal chute 101. Convex key slots 103 are opened at the front and rear ends of the activity perforation 102.

The clamp 6 is driven by the lifting push rod 5 to move upward from below the horizontal slide table 1 until it passes through the gear workpieces 7. Then, the forward and reverse motor 606 in the clamp 6 operates, and the driving gear 608 rotates along with the rotating shaft 607 and drives the two driven pressure plates 609 on both sides to extend out from the shell of the clamp 6. The two extended driven pressure plates 609 can reliably clamp the gear workpieces 7. The gear workpieces 7 can be adjusted in height position by using the lifting push rod 5 according to requirements. After the machining operations such as grinding of the gear workpieces 7 are completed, they are reset. The reverse motor 606 rotates in reverse, causing the driven pressure plates 609 to be retracted into the shell. Then, the lifting push rod 5 drives the clamp 6 to return to the position below the horizontal slide table 1 again. At this time, the machined gear workpieces 7 are in an unlocked state, and they can be transferred by using equipment such as a suction cup manipulator. By repeating the above steps, rapid clamping and releasing of the gear workpieces and automatic loading and unloading can be achieved, which is beneficial to industrial production.
