Abstract

The utility model discloses a milling machine. Both sides of the milling machine body are respectively provided with a set of milling heads. The milling head is formed by a milling cutter which is fixed to a main shaft, wherein the outside of the main shaft is in sleeve joint with a sliding sleeve, a propeller shaft is arranged among the sliding sleeve and cams, the two cams are in coaxial connection by a cam shaft which is connected in a rotating mode with a cam driving box, a tension spring is arranged between the sliding sleeve and the milling machine body, and a clamping device is arranged between the two sets of milling heads. The utility model which adopts a single milling machine to process a balance shaft has the characteristics of low manufacturing cost, high efficiency, low energy consumption, high rate of finished products and low labor intensity.

Description

A kind of milling machine

One, technical field

The utility model belongs to the machining equipment technical field, especially relates to a kind of milling machine that is used for the processing diesel engine trunnion shaft.

Two, background technology

The trunnion shaft of diesel engine is one of main rotary part on the complete machine, the quality of its quality influences machine performance, and the processing of trunnion shaft at present all is the production decisions that adopt traditional unit hilted broadsword list operation, electricity consumption, the personnel selection many, equipment needed thereby is more, needs multiple operation to cooperate, and labour intensity is big, production efficiency is low, consumable material is many, the production cost height, and qualification rate is also lower simultaneously.

Three, summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and adopt the separate unit milling machine, cost is low, efficient is high, less energy consumption, lumber recovery height, cost is low, labour intensity is little milling machine.

The purpose of this utility model is to realize like this, a kind of milling machine, form by lathe bed and milling head, be characterized in that respectively being equipped with one in the both sides of lathe bed overlaps milling head, milling head is that milling cutter is fixed on the main shaft, main shaft connects external motor by belt, spindle jacket is connected to sliding sleeve, be fixed with cardan shaft on the sliding sleeve, the other end of cardan shaft contacts with cam face, and two cams are by the coaxial connection of camshaft, and camshaft is connected rotation with the cam drive case, be provided with extension spring between sliding sleeve and lathe bed, be provided with anchor clamps between two cover milling heads.

In order further to realize the purpose of this utility model, can be to be fixed with five milling cutters on each main shaft.

In order further to realize the purpose of this utility model, can also be on cardan shaft, to be provided with bearing with the cam contact position.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model employing respectively is equipped with a cover milling head in the both sides of lathe bed, milling head is that milling cutter is fixed on the main shaft, main shaft connects external motor by belt, spindle jacket is connected to sliding sleeve, be fixed with cardan shaft on the sliding sleeve, the other end of cardan shaft contacts with cam face, two cams are by the coaxial connection of camshaft, camshaft is connected rotation with the cam drive case, be provided with extension spring between sliding sleeve and lathe bed, be provided with anchor clamps between two cover milling heads, by the fixing processed parts of clamp, keep processed parts motionless, rotation with milling cutter comes processing component, adopt two coaxial cover milling heads to process simultaneously simultaneously in both sides, guaranteed machining accuracy, reduced energy consumption, lumber recovery improves greatly, only need a people can carry out whole manufacturing procedure, reduced cost, be fixed with five milling cutters on each main shaft, a feed can be finished whole milling operations of trunnion shaft, on cardan shaft, be provided with bearing, reduced the friction between cardan shaft and cam, prolonged service life with the cam contact position.

Four, description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the partial sectional view of Fig. 1.

Fig. 3 is an another kind of structural representation of the present utility model.

Five, specific embodiments

Embodiment 1, a kind of milling machine, with reference to Fig. 1, be that a cover milling head 2 respectively is installed in the both sides of lathe bed 1, every cover milling head 2 is that milling cutter 3 is fixed on the main shaft 4, main shaft 4 connects the outside motor that power is provided by belt, the main shaft 4 outer sliding sleeves 5 that are socketed with, be fixed with cardan shaft 6 on the sliding sleeve 5, the other end of cardan shaft 6 contacts with cam 7 surfaces, and two cams 7 are by camshaft 8 coaxial connections, camshaft 8 is connected rotation with cam drive case 9,1 of sliding sleeve 5 and lathe bed are provided with extension spring 10, two 2 of milling heads of cover and are provided with anchor clamps 11, and this constitutes a kind of structure of the present utility model.

Embodiment 2, and a kind of milling machine with reference to Fig. 1, Fig. 2, Fig. 3, is on the basis of embodiment, is fixed with five milling cutters 3 on each main shaft 4, is provided with bearing 12 with cam 7 contact positions on the cardan shaft 6, and other and embodiment 1 are identical.

When using the utility model, processed raw material is put in the anchor clamps 11 steps up, start milling machine, milling cutter 3 rotates under the drive of main shaft 4, two cams 7 also rotate under the drive of camshaft 8 simultaneously simultaneously, cam 7 promotes cardan shafts 6, and to overcome the pulling force of extension spring 10 close to parts, drives sliding sleeve 5, main shaft 4 and milling cutter 3 contact sites and processing, and milling cutter 3 milling parts are processed, when forwarding cam 7 sunk parts to, cardan shaft 6 loses thrust, is pulled under the pulling force of extension spring 10, finishes time processing.
