Abstract

The utility model discloses a novel common lathe saddle rotation positioning structure, which comprises a saddle turntable, a slider, a saddle, a screw and a handle. The screw is fixedly connected onto the slider, the slider is fixed onto the saddle turntable, the saddle is rotatably connected onto the slider and penetrates into the screw, the handle is connected to the upper end of the screw in a threaded manner, a groove is arranged on the slider, a positioning pin is connected onto the groove through a spring, a plurality of straight flutes are arranged at the bottom end of the saddle, a shaft sleeve is sleeved in the straight flutes, and the positioning pin is slidably connected with the shaft sleeve. The novel common lathe saddle rotation positioning structure has the advantages of simple structure, simplicity in operation and accuracy in positioning.

Description

A kind of novel engine lathe knife rest revolution location structure

Technical field

The utility model relates to the lathe equipments field, refers more particularly to a kind of novel engine lathe knife rest revolution location structure.

Background technology

In some machining enterprises, some old C630 engine lathe is using at present, and this a part of lathe is mainly used in roughing, promptly blank is carried out roughing, stays 1-2 millimeter surplus to give numerically controlled lathe fine finishining.Because the C630 engine lathe will unclamp the handle on the knife rest earlier when being designed to the knife rest revolution; The elastic force that utilizes big spring is with knife rest jack-up from the gliding mass of knife rest top; Knife rest also leaves the alignment pin on the gliding mass of knife rest top simultaneously, rotates the position of needs by hand, and then the handle on the locking knife rest.Because the knife rest lower plane leaves contact-making surface on the gliding mass of knife rest top when rotated, at this moment iron filings are easy to run into the contact-making surface between knife rest and the knife rest top gliding mass, and the time has been grown and can cause the wearing and tearing of two contact-making surfaces, thereby influences the machining accuracy of lathe.

The utility model content

The purpose of the utility model is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, simple to operate, accurate positioning, practical novel engine lathe knife rest revolution location structure is provided.

The utility model is realized through following mode:

A kind of novel engine lathe knife rest revolution location structure comprises knife rest rotating disk, gliding mass, knife rest, screw rod, handle, and screw rod is fixedly connected on the gliding mass; Gliding mass is fixed on the knife rest rotating disk; Blade holder turns is connected on the gliding mass, and is arranged within the screw rod; Handle is threadedly connected to the upper end of screw rod; It is characterized in that:

Offer groove on the gliding mass; Connect an alignment pin through spring on the said groove;

The bottom of described knife rest offers several straight troughs; Be arranged with axle sleeve in the described straight trough; Described alignment pin is slidingly connected with axle sleeve mutually.

The top of said alignment pin is the inclined-plane, and through Quenching Treatment; Spring housing is located in the alignment pin.

The utility model is processed with groove on gliding mass, alignment pin and spring are housed in it; Axle sleeve on alignment pin and the knife rest in several straight troughs is slidingly connected mutually; When knife rest will rotate, first release handle, rotating turret; Alignment pin can descend under stressed situation, and knife rest is just rotatable, when knife rest rotates to next straight trough hole and alignment pin alignment; Alignment pin can rise under spring action, and alignment pin then slides in the axle sleeve, reaches the location; At this moment, set lever gets final product.

The utility model is in whole rotary course, and the knife rest lower plane does not leave the contact-making surface on the gliding mass, does not just exist iron filings can run in the contact-making surface, has reduced the wearing and tearing of lathe like this, has also improved the machining accuracy of lathe.

In sum, the utility model is that a kind of structural design is simple, operating maintenance convenient, practical novel engine lathe knife rest turns round location structure.

Description of drawings

Fig. 1 the utility model structural representation.

The specific embodiment

Combine accompanying drawing at present, the utility model specific embodiment be detailed:

As shown in Figure 1, a kind of novel engine lathe knife rest revolution location structure comprises knife rest rotating disk 1, gliding mass 2, knife rest 6, screw rod 7, handle 8, and screw rod 7 is fixedly connected on the gliding mass 2; Gliding mass 2 is fixed on the knife rest rotating disk 1; Knife rest 6 is rotationally connected with on the gliding mass 2, and is arranged within the screw rod 7; Handle 8 is threadedly connected to the upper end of screw rod 7; It is characterized in that:

Offer groove 21 on the gliding mass 2; Connect an alignment pin 4 through spring 3 on the said groove 21;

The bottom of described knife rest 6 offers several straight troughs 61; Be arranged with axle sleeve 5 in the described straight trough 61; Described alignment pin 4 is slidingly connected with axle sleeve 5 mutually.

The top of said alignment pin 4 is the inclined-plane, helps being slidingly connected with axle sleeve 5; And through Quenching Treatment; Spring 3 is set in the alignment pin 4.

The utility model is processed with groove 21 on gliding mass 2, alignment pin 4 and spring 3 are housed in it; Axle sleeves 5 on alignment pin 4 and the knife rest 6 in several straight troughs 61 are slidingly connected mutually; When knife rest 6 will rotate, first release handle 8, rotating turret 6; Alignment pin 4 can descend under stressed situation; Knife rest 6 is just rotatable, and when knife rest 6 rotated to next straight trough 61 holes and alignment pin 4 alignment, alignment pin 4 can rise under spring 3 effects; 4 of alignment pins slide in the axle sleeve 5, reach the location; At this moment, set lever 8 gets final product.
