Description

Technical Field

[0001] The utility model belongs to the field of cross shaft processing, in particular to a cross shaft multi-station punching device. Background Art

[0002] The cross shaft is a mechanical component that realizes variable-angle power transmission. It is mainly used in positions where the direction of the transmission axis needs to be changed. It is a key component of the universal transmission device. The design of the cross shaft usually includes a central shaft with a short shaft perpendicular to the central shaft at each end of the central shaft to form a cross shape. These short shafts can be inserted into the holes of the shaft fork. When there is an angular displacement between the two transmission shafts, the shaft forks will rotate around their respective fixed axes to achieve power transmission. To ensure that the bearings and rotating parts are fully lubricated, reduce wear and extend service life, a lubrication channel is usually set in the central axis of the cross shaft. The lubricating oil can reach the inside of the cross shaft through this channel and flow through the bearing surface, effectively reducing friction and heat.

[0003] The lubrication channel is a threaded hole. During processing, the light hole must be processed first, and then the internal thread can be processed. Therefore, after the light hole of the cross shaft is processed, it needs to be transferred for tapping. The lubrication channels on cross shafts of different sizes have different inclination angles. The lubrication channels of larger cross shafts do not need to be tilted, which is more convenient to process. However, when processing the lubrication channels of smaller cross shafts, the cross shaft often needs to be tilted. After the processing station is transferred, secondary clamping is required, which can easily affect the processing accuracy and the safety of the tap. For lubrication channels with different inclination angles, a variety of fixtures need to be configured to fix the cross shaft, and the versatility is weak. Summary of the invention

[0004] The utility model provides a cross-axis multi-station punching device. A plurality of clamping devices are arranged on a turntable, and a plurality of processing stations are configured. Each station completes a process. The cross-axis is clamped once at the clamping device and all processes can be rotated to complete the processing. The processing efficiency is high and the processing accuracy can be guaranteed.

[0005] The utility model provides a cross-shaft multi-station punching device. The clamping device used can be adjusted according to different inclination angles of a lubrication channel, can adapt to different cross-shaft punching processing needs, and enhances the versatility of the device.

Depending on the complexity of the workpiece processing, sometimes the stations will increase. For example, two punching stations are required. The present application adds a first station for point hole positioning before drilling. This is mainly because the axial direction of the drilling of the present application is not perpendicular to the plane to be processed. In order to avoid damage to the drill bit and ensure processing safety, as well as to avoid slipping, a point hole is first positioned on the plane to be processed of the workpiece to ensure the position accuracy of the drilling, while also ensuring The cross shaft to be processed is loaded and clamped on the clamping device from the fourth station, and then the rotating disk is driven by the driving device to rotate, and then it is turned to the first station to locate the hole on the plane to be processed of the cross shaft, and then it is turned to the clamping device on the fourth station for loading and clamping again. After the hole is pointed, the cross shaft is turned to the second station for drilling, and then it is turned to the third station for tapping, and then it is turned to the fourth station for unloading after tapping. After unloading, the vacant clamping device is clamped again to clamp the cross shaft to be processed.

The clamping of the cross shaft can be done manually, or it can be equipped with an automatic loading mechanism for automatic loading;

[0022] 3. The mounting seat is arranged on the frame and can rotate relative to the frame.

A cross shaft accommodating space is provided on the front of the mounting seat. The accommodating space is a cross-shaped cavity structure adapted to the shape of the cross shaft, including a central cavity 5 corresponding to the central part of the cross shaft, a cross cavity 6 corresponding to the short axis part of the cross shaft, and a stop convex between adjacent cross cavities. The cross cavity is located at the diagonal position of the mounting seat block, and the four stop convexities are located at the four side positions of the mounting seat block. Of course, the setting of the accommodating cavity must ensure that the punching position of the cross shaft is exposed without interference.

Adjust the inclination angle of the mounting seat according to the inclination angle of the hole to be processed on the workpiece. The mounting seat rotates around the pin at the circular hole, and the locking screw slides in the arc groove. After the mounting seat is adjusted into place, tighten the locking screw to fix the mounting seat, and then rotate the fixing screw so that the ends of the two fixing screws are against the outer surface of the locking screw head.
