Abstract

The utility model discloses a lathe including a headstock case with a main shaft and a lathe body, a clamp disc is connected onto the main shaft, a large slide carriage is arranged on the lathe body, a slide carriage case is arranged on the large slide carriage and is connected with a motor through a light bar, and a shaft coupling is arranged between the motor and the light bar. The lathe provided directly drives the slide carriage case to move by means of the motor, realizes the feeding process, thereby being simple in structure, low in cost, and accurate in feeding.

Description

A kind of lathe

Technical field

The utility model relates to a kind of machining equipment, particularly a kind of lathe.

Background technology

Lathe is mainly used in the workpiece that processing has rotary surface, take cylinder as main, is in machine-building and repair factory, to use a widest class lathe.Traditional lathe is by gear transmission structure complicated in geared head, by gear graduation, the power in geared head is separated to a part and reach slip crate through feed rod, the straight-line feed that converts rotatablely moving of feed rod to knife rest by the switching mechanism in slip crate again moves, and then realizes the feed in length and breadth of knife rest.Such feed transmission mechanism complex structure, cost is high, and transmission efficiency is low.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of lathe, to reach the object that can reduce costs, improve transmission efficiency.

For achieving the above object, the technical solution of the utility model is as follows:

, comprise geared head and vehicle body that main shaft is housed, on described main shaft, be connected with chuck, on described vehicle body, big cargo chute is housed, on described big cargo chute, slip crate is installed, described slip crate is connected with motor by feed rod, between described motor and described feed rod, shaft coupling is installed.

Preferably, described motor is installed on the outside of described geared head, by long feed rod, is connected with slip crate, and the end of described long feed rod is connected with bearing support block.

Preferably, described motor is installed on the outside of described slip crate, by short feed rod, is connected with slip crate.

By technique scheme, the lathe that the utility model provides, by driven by motor slip crate, is realized the feed of lathe, and when lathe length is less than 3.5 meters, motor can be installed on the outside of geared head, by a long feed rod, is connected with slip crate, drives slip crate to move; When lathe length surpasses 3.5 meters, motor is directly installed on slip crate, by a short feed rod drive slip crate move ，Gai mechanism install simple, save time, saving of labor, can reduce costs, and transmission efficiency is high.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.

Fig. 1 is the schematic diagram of the utility model embodiment mono-disclosed lathe;

Fig. 2 is the transmission mechanism schematic diagram of the utility model embodiment mono-disclosed lathe;

Fig. 3 is the schematic diagram of the utility model embodiment bis-disclosed lathes;

Fig. 4 is the transmission mechanism schematic diagram of the utility model embodiment bis-disclosed lathes.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

The utility model provides a kind of lathe, and this lathe moves by the moving slip crate of motor straight tape splicing, and simple in structure, easy for installation, efficiency of transmission is high.

A kind of lathe, comprise geared head 2 and vehicle body 3 that main shaft 1 is housed, on described main shaft 1, be connected with chuck 4, big cargo chute 7 is housed on vehicle body 3, slip crate 5 is installed on big cargo chute 7, and slip crate 5 is connected with motor 6 by feed rod, by motor 6, is driven and is realized feed, by the display 13 on slip crate 5, can control the program of feed, by manual spanner 8, can carry out lathe feed all around and regulate.

Embodiment mono-, as shown in Figure 1, motor 6 is installed on the outside of geared head 2, after the output of shaft coupling 9, by long feed rod 10, is connected with slip crate 5, and the end of long feed rod 10 is connected with bearing support block 11, this transmission mechanism is applicable to length and is no more than the lathe of 3.5 meters, the power of being exported by motor 6, after speed governing, by long feed rod 10 outputs, drives slip crate 5 to realize feed, Fig. 2 a is the front schematic view of the transmission mechanism of embodiment mono-, and Fig. 2 b is the top view of the transmission mechanism of embodiment mono-.

Embodiment bis-, as shown in Figure 3, motor 6 is installed on the outside of slip crate 5, after the output of shaft coupling 9, by short feed rod 12, is connected with slip crate 5, the lathe transmission mechanism of this structure is applicable to length and surpasses 3.5 meters of lathes that even reach 7～8 meters, if this lathe is again through feed rod transmission, feed rod is long can produce vibrations, the precision of impact processing in process, and can cause the loss of power, therefore, directly motor 6 is arranged on slip crate 5, has reduced the loss of energy.With reference to figure 4a, be the front view of the transmission mechanism of embodiment bis-, the top view that Fig. 4 b is transmission mechanism.

The lathe that the utility model provides, by driven by motor slip crate, is realized the feed of lathe, and when lathe length is less than 3.5 meters, motor can be installed on the outside of geared head, by a long feed rod, is connected with slip crate, drives slip crate to move; When lathe length surpasses 3.5 meters, motor is directly installed on slip crate, by a short feed rod drive slip crate move ，Gai mechanism install simple, save time, saving of labor, can reduce costs, and transmission efficiency is high.

Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
