Abstract

The utility model discloses a machine tool bed, which comprises a bed body, air removing grooves, a tail seat moving V-shaped surface, a tail seat moving surface, a bed saddle moving V-shaped surface, a tail seat moving surface, a bed body sliding surface and a bed saddle limiting groove. The bed body is integrated with a base, the air removing grooves are arranged on the two ends of the top of the bed body, the tail seat moving V-shaped surface and the tail seat moving surface are respectively arranged on the inner edge and the outer edge of an air removing groove on one end, the bed saddle moving V-shaped surface and the tail seat moving surface are respectively arranged on the inner edge and the outer edge of the other air removing groove on the other end, the bed body sliding surface is arranged below the tail end moving surface on the end with the bed saddle moving V-shaped surface and the tail seat moving V-shaped surface, and the bed saddle limiting groove is arranged on the bed body sliding surface close to the bed body. The machine tool bed is characterized in that a wear-resistant layer formed through quenching is arranged on the bed body sliding surface. With the structure, the utility model has positive effects, improves the precision of the guide rail of the machine tool, and reduces the maintenance cost and the service cost.

Description

The lathe lathe bed

Technical field

The utility model relates to machining equipment, particularly a kind of lathe lathe bed that can reduce use cost and prolong guide rail service life and raising guide precision.

Background technology

The lathe of prior art enters foreign matters such as dust or iron filings with the guide pass that is provided with on the lathe bed owing to be easy to and causes wearing and tearing between guide rail and the guide pass, make the very fast forfeiture of precision of machine tool guideway cause the precision of processing parts to reduce, the high and shortening in service life of machine upkeep cost.

For solving above-mentioned deficiency, mainly with the guide rail high-frequency quenching, this has improved the machining accuracy and the service life that has prolonged machine tool of lathe to a certain extent on the present machine tool market.But the bed ways glide slope in the machine tool still because and the relative motion of guide rail and enter dust between them or the violent friction of foreign matter such as iron filings and cause very quick-wearing of guide pass, thereby the precision forfeiture, the rigidity of guide rail, the vibration resistance that make machine tool guideway weaken the precision that causes processing parts and reduce, and this has just improved maintenance cost, has reduced operating efficiency and use cost.

In sum, the deficiency of prior art existence is: maintenance cost height, service life shorten and the use cost height.

Summary of the invention

The purpose of this utility model is in order to overcome the prior art above shortcomings, a kind of lathe lathe bed that can reduce use cost and improve machining accuracy to be provided.

The technical solution adopted in the utility model is such, be a kind of lathe lathe bed, comprise with base be one the lathe bed body, be arranged on the groove of cooling down at two ends, lathe bed body top, saddle that the tailstock that is arranged at outside in the groove of cooling down of an end respectively moves V-type face and tailstock all-moving surface and is arranged at the outer inner edge of groove of cooling down of the other end respectively moves the V-type face and the tailstock all-moving surface, be provided with the lathe bed glide slope and have the saddle stopper slot at the lathe bed glide slope near lathe bed body place below saddle moves the tailstock all-moving surface that V-type face and tailstock move V-type face one end; It is characterized in that: on described lathe bed glide slope, have the wearing layer that quenches and form.

1

The advantage that the utility model has owing to said structure is conspicuous: because the lathe bed glide slope is provided with quench hardened case, this has just improved the hardness of lathe bed glide slope, thereby improved wearability, this just can be because of entering foreign matter generation guide rail accelerated wear tests such as dust between guide rail and the lathe bed glide slope or iron filings, and influence the machining accuracy of machine tool, also further reduced maintenance and use cost.

Description of drawings

The utility model said structure can further specify by the non-limiting embodiment that accompanying drawing provides.

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

In the accompanying drawing: 1, lathe bed body; 2, base; 3, tailstock moves the V-type face; 4, tailstock all-moving surface; 5, saddle moves the V-type face; 6, lathe bed glide slope; 7, saddle stopper slot; 8, wearing layer; 9, the groove of cooling down.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to accompanying drawing 1, lathe lathe bed among the figure, comprise with base 2 for the lathe bed body 1 of one, be arranged on the groove 9 of cooling down at two ends, lathe bed body 1 top, saddle that the tailstock that is arranged at outside in the groove 9 of cooling down of an end respectively moves V-type face 3 and tailstock all-moving surface 4 and is arranged at the groove 9 outer inner edges of cooling down of the other end respectively moves V-type face 5 and tailstock all-moving surface 4, be provided with lathe bed glide slope 6 and have saddle stopper slot 7 at lathe bed glide slope 6 close lathe bed body 1 places below saddle moves the tailstock all-moving surface 4 that V-type face 5 and tailstock move V-type face 3 one ends; It is characterized in that: on described lathe bed glide slope 6, have the wearing layer 8 that quenches and form.

Wearing layer 8 in the said structure adopts high-frequency quenching.

In sum, the utility model is easy to implement, because the effect that described structure is brought is positive, has prolonged the guide precision of lathe, has reduced maintenance and use cost.
