Detailed description of the invention
All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this description (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below the structure of the grinding attachment to the utility model Crankshaft Grinding bracket watt mouth and principle are described in detail.Wherein, need first simply to introduce Crankshaft Grinding.Crankshaft Grinding is the device of polishing to the connecting rod neck of bent axle, gland is specifically utilized to be pressed on the bracket of grinding machine by the technique neck of crankshaft two end, adjustment makes crank-shaft link neck center and the grinding machine spindle centre of gyration point-blank, and emery wheel on grinding carriage is aimed at the connecting rod neck of bent axle, then the main shaft rotating grinding machine makes crankshaft rotating, make the emery wheel on grinding carriage rotate simultaneously, realize grinding.Bracket watt mouth is then the part that bracket directly contacts with bent axle.
Fig. 1 shows the structural representation of the grinding attachment of the Crankshaft Grinding bracket watt mouth according to the utility model exemplary embodiment, Fig. 2 A shows the structural representation utilizing the grinding attachment of the bracket of Crankshaft Grinding shown in Fig. 1 watt mouth to carry out bracket watt mouth grinding, and Fig. 2 B shows the sectional view intercepted along A-A line in Fig. 2 A.
As shown in Figure 1, Figure 2 shown in A and Fig. 2 B, according to exemplary embodiment of the present utility model, the grinding attachment 20 of described Crankshaft Grinding bracket watt mouth comprises base 1, mount pad 2, electro spindle 4, gland 3 and little emery wheel 7.
Particularly, grinding attachment 20 is arranged on the grinding carriage 10 of Crankshaft Grinding by base 1.Base 1 one aspect is as the main load-supporting part of grinding attachment 20 and installing component, grinding attachment 20 can be made to be fixed on grinding carriage 10 on the other hand, and then utilize the position of the feeding of grinding carriage 10 and mobile adjustment grinding attachment 20 to match with bracket watt mouth 40.Wherein, the size of base 1 can according to the center specific design of the feed distance of grinder wheel frame 10 and little emery wheel.Mount pad 2 is arranged on base 1, and electro spindle 4 is fixed on mount pad 2 by gland 3.Mount pad 2 is mainly used in supporting electro spindle 4, and electro spindle 4 can realize the action rotated.The size of mount pad 2 can according to the size of base 1 and the size of electro spindle and the width specific design of bracket watt mouth 40, and 3, gland is for fixing electro spindle 4, and the utility model does not specifically limit its structure.Little emery wheel 7 is arranged on the end of electro spindle 4 and can rotates under the drive of electro spindle 4, can carry out grinding thus to bracket watt mouth 40.In addition, each assembly of connector 6 pairs of grinding attachments 20 can be adopted to assemble.
Preferably, grinding attachment 20 also comprises frequency converter (not shown), and frequency converter is electrically connected the rotary speed realizing little emery wheel 7 and regulates with electro spindle 4.Also, namely, in grinding process, can the rotary speed of little emery wheel 7 be regulated by frequency converter and control grinding speed.
