A multi-station drilling and milling machine tool

Abstract

The invention discloses a multi-station drilling and milling machine tool. The multi-station drilling and milling machine tool comprises a base, an indexing plate and a motor; a machining mechanism is arranged on the base; multiple stations are uniformly distributed on the indexing plate; fixtures are arranged on the stations, and include vertical plats; V-shaped grooves are formed in the vertical plates; turning plates are arranged above the vertical plates; grooves and machining grooves are formed in the top ends of the turning plates; pin plates for supporting the turning plates are arranged in middles of the turning plates; connecting heads perpendicular to the turning plates are arranged at the bottom ends of the turning plates; the bottom ends of the connecting heads are connected with first driving elements; through holes are formed in the pin plates; stoppers are arranged in the through holes; one ends of the stoppers are butted against workpieces; and the other ends of the stoppers are connected with second driving elements. The multi-station drilling and milling machine tool adopts multi-procedure machining, only needs once clamping and positioning, and reduces the workpiece clamping and positioning times, so that the clamping time and workloads can be reduced, and the machining efficiency is improved. The multi-station drilling and milling machine tool guarantees the clamping consistency in each procedure, reduces the machining errors caused by different clamping and positioning, and improves the machining precision.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a multi-station drilling and milling machine tool. Background technique [0002] The NVH performance of the automotive drive train is an important part of the NVH performance of the vehicle. Common drive train NVH problems include transmission noise, shift cable vibration, etc. [0003] In the process of automobile design and development, drivetrain components such as clutches and transmissions generally adopt existing relatively mature structures or directly use previous products, and the optimization space is generally small. Therefore, the design and optimization of the transmission path around the transmission occupies a large proportion of the NVH performance development of the powertrain. Shift cables, clutch lines, etc. are important transmission paths of the transmission system, and their optimal design is an important direction for NVH performance improveme...

Problems solved by technology

[0004] Among them, adding a counterweight to the shift cable is a commonly used technical solution at present. By adjusting the weight and arrangement position of the counterweight, the effect of the counterweight can be affected, and the adjustment space is large.

At present, the counterweight needs to go through five processes in the manufacturing process: drilling 13.2mm holes, centering 6.7mm holes, drilling 6.7mm holes, drilling 5.2mm threaded holes, and tapping, which cannot be completed on one machine tool. After processing on one machine tool, it is necessary to remove the counterweight and then transfer it to another machine tool for clamping and positioning. Such multiple clamping and positioning not only increase the workload and reduce the processing efficiency, Moreover, since the positioning of each clamping cannot be guaranteed to be exactly the same, it also affects the accuracy of processing.
