Abstract

The utility model belongs to the technical field of lathe tool rest equipment, and particularly relates to a combination-type tool rest used for a lathe. The combination-type tool rest used for the lathe comprises a sliding tool rest body (1), a tool I (2), a compression bolt I (3), a tool II (4) and a compression bolt II (5). The tool I (2) is arranged at the front end of the sliding tool rest (1), and the tool I (2) is fixed onto the sliding tool rest (1) through the compression bolt I (3). The combination-type tool rest used for the lathe is characterized in that the tool II (4) is arranged on one side of the tool I (2), the tool II (4) is fixed onto the sliding tool rest body (1) through the compression bolt II (5), the tool I (2) is located on one side on the tool II (4) and the tool I (2) and the tool II (4) are arranged in parallel. One or two tools can be installed on the combination-type tool rest at the same time for conducting thread, flat end face and chamfer machining, great convenience is brought to users and the working efficiency is increased.

Description

A kind of lathe Combined knife holder

Technical field

The utility model belongs to lathe saddle equipment technical field, is specifically related to a kind of lathe Combined knife holder.

Background technology

Lathe claims again lathe, uses the workman of lathe to be called " turner ", and in mechanical processing industry, lathe is considered to the work " machine tool " of all devices.Lathe is mainly used in machining shaft, dish, cover and other and has the workpiece of rotary surface, take cylinder as main, is in machine-building and repair factory, to use a widest class lathe.

Chief component parts have: main spindle box, change gear box, feed box, slip crate, knife rest, tailstock, feed rod, leading screw, lathe bed, cabinet base and cooling device, as the knife rest of the final executing agency's terminal of lathe, knife rest has two-layer slide plate (in, small slide plate), saddle and tool-post structure jointly to form.Be used for installing lathe tool and drive lathe tool to make longitudinal, horizontal or oblique movement.

Existing engine lathe is as a class of radix maximum, in mechanical processing process, still occupy googol amount, although full automatic machining center or numerically controlled lathe are in machining accuracy, speed, efficiency is all occupied the right advantage of determining, but for the not high parts of those production added values, utilize high-grade, precision and advanced equipment to add and seem man-hour not to one's profit, because though common lathe is compared and is not taken advantage with advanced equipments of high grade and precision at aspects such as precision, but under the prerequisite of economic factors such as reducing costs, engine lathe is able to occupy a tiny space in common mechanical processing process.

A cutter is generally all installed on existing knife rest, in carrying out the process of axle processing, all first with the first face work of lathe tool, then knife rest is carried out to translation-angle and carry out chamfering, in this process, need knife rest to move to after rear end rotating turret again, could implement the process of next stage.

Summary of the invention

The purpose of this utility model is exactly that a kind of lathe Combined knife holder that one or two cutters can be installed simultaneously carry out screw thread, planar end surface, chamfer machining will be provided.

The utility model is achieved through the following technical solutions:

A kind of lathe Combined knife holder, comprise saddle 1, cutter I 2, hold-down bolt I 3, cutter II 4 and hold-down bolt II 5, wherein saddle 1 front end is provided with cutter I 2, cutter I 2 is fixed on saddle 1 by hold-down bolt I 3, it is characterized in that: described cutter I 2 one sides are provided with cutter II 4, and cutter II 4 is fixed on saddle 1 by hold-down bolt II 5.

Described cutter I 2 is positioned at a side in cutter II 4, and cutter I 2 and cutter II 4 are arranged in parallel.

Between described hold-down bolt I 3 and hold-down bolt II 5 center lines and saddle 1 central axis, there is angle.

Compared with prior art, the beneficial effects of the utility model are:

The saddle 1 that the utility model provides, cutter I 2, hold-down bolt I 3, cutter II 4 and hold-down bolt II 5, utilize hold-down bolt I 3 and hold-down bolt II 5 that cutter I 2 and cutter II 4 are fixed on saddle 1, carrying out in process, cutter I 2 can be carried out the technical process of face work, and cutter II 4 because with cutter I 2 not on same axis, and between there is certain distance, make cutter II 4 can carry out the technical process of chamfering or cutting thread, making not need in process to restart after knife rest is exited to adjust the cutter that angle carries out chamfering or reinstall cutting thread processes.

The beneficial effects of the utility model are: the utility model can be installed one or two cutters simultaneously and carry out screw thread, planar end surface, chamfer machining, provides great convenience, and improved operating efficiency to user.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is plan structure schematic diagram of the present utility model

In figure: saddle 1, cutter I 2, hold-down bolt I 3, cutter II 4, hold-down bolt II 5.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

A kind of lathe Combined knife holder, comprises saddle 1, cutter I 2, hold-down bolt I 3, cutter II 4 and hold-down bolt II 5.

As shown in accompanying drawing 1,2, wherein saddle 1 front end is provided with cutter I 2, and cutter I 2 is fixed on saddle 1 by hold-down bolt I 3, and cutter I 2 one sides are provided with cutter II 4, and cutter II 4 is fixed on saddle 1 by hold-down bolt II 5.

Wherein cutter I 2 is positioned at a side in cutter II 4, and cutter I 2 and cutter II 4 are arranged in parallel.

Wherein between hold-down bolt I 3 and hold-down bolt II 5 center lines and saddle 1 central axis, there is angle.

The utility model is in the time of concrete use, utilize hold-down bolt I 3 and hold-down bolt II 5 that cutter I 2 and cutter II 4 are fixed on saddle 1, carrying out in process, cutter I 2 can be carried out the technical process of face work, and cutter II 4 because with cutter I 2 not on same axis, and between there is certain distance, make cutter II 4 can carry out the technical process of chamfering or cutting thread, make not need to restart after knife rest is exited to adjust the cutter that angle carries out chamfering or reinstall cutting thread and process in process.
