Abstract

The utility model discloses a two-station mechanism for machining main bearing seat, oil grooves and tile grooves. A milling head is horizontally provided with a station I and a station II, wherein, a cutter holder of the station I is provided with eight inserted-tooth two-edge cutters and five groove milling cutters. The cutter holder of the station II is provided with five groove milling cutters. Each cutter holder is provided with a sleeve gasket which adjusts an axial position of the cutter. Through special setting to the milling cutter, the two-station mechanism realizes one-time machining to eight side surfaces of a main bearing seat of a four-cylinder diesel engine, oil grooves and tile grooves. Furthermore the two-station mechanism has the following advantages: effectively reduced machining cost, high machining precision and high operation efficiency.

Description

The mechanism of a kind of two station machining spindle bearings and oil groove, watt groove

Technical field

The utility model relates to a kind of machining mechanism, the mechanism of particularly a kind of two station machining spindle bearings and oil groove, watt groove.

Background technology

The processing of body main bearing seat eight sides and oil groove, watt groove is an important content in the diesel-engine body processing, and special plane processing and Cutter Body Processing with Machining Center dual mode are arranged at present, and they have characteristics separately.The ratio of precision of Cutter Body Processing with Machining Center is higher, because of it has flexibility, can change the content of manufacturing procedure at any time, even changes the type of converted products, but its cost is relatively more expensive, and the processing beat is slower; Comparatively speaking, the machining accuracy of special plane processing is generally a little bit poorer a little, because of its relative stiffness, can not change processing content, is that multitool is processed simultaneously but its adopts, and it is very fast therefore to process beat.How with the combining a little of above-mentioned two kinds of processing modes, improving working (machining) efficiency and realize producing in enormous quantities when guaranteeing machining accuracy still is the problem that the diesel-engine body processing industry needs to be resolved hurrily.

The utility model content

The purpose of this utility model provides the mechanism of a kind of two station machining spindle bearings and oil groove, watt groove, have can reduce cost, precision height, characteristics that work efficiency is high.

For achieving the above object, by the following technical solutions:

The mechanism of a kind of two station machining spindle bearings and oil groove, watt groove has been horizontally disposed with station I and station II on milling head, wherein, eight iron chains tooth double knife-edge milling cutters and five are housed slotting cutter on the knife bar of station I; Five slotting cutters are housed on the knife bar of station II; Knife bar is provided with the spacer of adjusting the cutter axial location.

The utility model utilizes eight on the station I that iron chains tooth double knife-edge milling cutter and five is realized processing to body main bearing seat eight sides and watt groove to slotting cutter; Utilize five on the station II that slotting cutter is realized processing to the body oil groove, thereby only needing to have realized clamping can finish processing, effectively reduce processing cost body main bearing seat eight sides and oil groove, watt groove, and machining accuracy height, work efficiency height.

Description of drawings

According to embodiment and accompanying drawing the utility model is described in further detail below.

Fig. 1 is the structural representation of the mechanism of the described two station machining spindle bearings of the utility model embodiment and oil groove, watt groove;

Fig. 2 is the left view of Fig. 1.

Among the figure:

1, station I; 2 station II; 3, the knife bar of station I; 4, the knife bar of station II; 5, spacer; 6, milling head.

The specific embodiment

Below in conjunction with accompanying drawing, further specify the utility model by embodiment.

As shown in Figure 1, the mechanism of two station machining spindle bearings described in the utility model and oil groove, watt groove has been horizontally disposed with station I 1 and station II 2 on milling head 6, wherein, eight iron chains tooth double knife-edge milling cutters and five is housed slotting cutter on the knife bar 3 of station I; Five slotting cutters are housed on the knife bar 4 of station II; Knife bar is provided with the spacer 5 of adjusting the cutter axial location.

During use, earlier with the workpiece to be processed clamping on station I 1, milling head 6 axially down moves along lathe Z, begins to utilize eight iron chains tooth double knife-edge milling cutters and five that slotting cutter machining body main bearing seat side is reached watt groove, after machining, milling head 6 moves upward again, workbench outwards moves to station II along the lathe Y-axis, and milling head 6 moves downward, and utilizes five slotting cutter processing body oil grooves, finish back milling head 6 and move upward, finish operation.

Claims

1. the mechanism of station machining spindle bearing and oil groove, watt groove is characterized in that, has been horizontally disposed with station I and station II on milling head, wherein, eight iron chains tooth double knife-edge milling cutters and five is housed slotting cutter on the knife bar of station I; Five slotting cutters are housed on the knife bar of station II; Knife bar is provided with the spacer of adjusting the cutter axial location.
