Description

In the production process of synchronous wheel, edge pressing is an important link. The quality of edge pressing process directly affects the final performance and service life of synchronous wheel. Generally, an edge pressing machine is used to perform edge pressing process on synchronous wheel. For example, the existing patent with announcement number CN203235802U discloses "an edge pressing machine, including a frame, the frame is composed of a base, a vertical pole arranged on the base and a horizontal pole arranged horizontally on the upper end of the vertical pole, a motor is installed on the base, a horizontal shaft is rotatably arranged on the vertical pole, the horizontal shaft is driven by the motor, and a lower pressing wheel is fixedly installed on the horizontal shaft, a push rod is movably arranged on the cross rod, a pin is fixedly installed on the lower end of the push rod, and an upper pressing wheel is rotatably connected to the pin", it can be seen that the application describes a kind of edge pressing machine that can perform edge pressing process on synchronous wheel, which mainly relies on upper and lower pressing wheels to realize edge pressing process on synchronous wheel;

[0003] When this type of edge pressing machine in the prior art is in use, the upper pressing wheel can be driven to rise and fall by rotating the upper handwheel, thereby adjusting the distance between the upper and lower pressing wheels. However, the upper handwheel does not take effective and stable limiting measures after rotation, and it is easy to rotate again during the subsequent edge pressing process, thereby reducing the height stability of the upper pressing wheel, and also reducing the overall edge pressing stability and edge pressing quality. For this reason, the utility model needs to improve and optimize the existing synchronous wheel production edge pressing machine. Utility Model Content

[0025] A base 11, a vertical plate 12 welded and fixed to the top surface of the base 11, and a top seat 13 welded and fixed to the top of the vertical plate 12;

[0026] A lower pressure wheel 22 is installed on the left surface of the vertical plate 12 through a bearing, a motor 21 is fixedly installed on the right surface of the vertical plate 12 through bolts and the output end is connected to the lower pressure wheel 22, a lifting seat 24 is slidably installed on the left surface of the vertical plate 12, two support plates 25 are welded and fixed at the bottom of the lifting seat 24, an upper pressure wheel 23 is rotatably installed between the two support plates 25 and is above the lower pressure wheel 22 through a bearing, a screw rod 26 is rotatably installed on the top of the lifting seat 24 through a bearing, and a nut seat 28 is welded and fixed to the top surface of the top seat 13. After the motor 21 is started, the lower pressure wheel 22 will be driven to rotate, and then the edge of the synchronous wheel that needs to be pressed is pushed between the lower pressing wheel 22 and the upper pressing wheel 23 to press the synchronous wheel. The top end of the screw rod 26 passes through the surface of the top seat 13 and penetrates to the top of the nut seat 28. The top end of the screw rod 26 is fixed with a handwheel 27 by bolts relative to the top of the nut seat 28. Subsequently, the screw rod 26 and the lifting seat 24 can be driven to rise and fall to a certain extent by the rotation of the handwheel 27, thereby changing the distance between the upper pressing wheel 23 and the lower pressing wheel 22 to meet the pressing requirements of synchronous wheels of different sizes.

[0027] The limit mechanism 3 is arranged at the top of the vertical plate 12, including a movable side plate 31 movably installed on the side of the vertical plate 12, a movable top plate 35 welded and fixed at the top of the movable side plate 31, a limit clamping rod 36 installed on the top surface of the movable top plate 35, and a plurality of circular clamping holes 271 corresponding to the limit mechanism 3 are opened on the surface of the hand wheel 27.
