Description

Novel numerical control vertical lathe composite tool rest

Technical Field

The utility model belongs to the technical field of lathe processing accessory in the machining and specifically relates to a novel compound knife rest of numerical control merry go round machine.

Background

The tool rest is a very important part of the numerical control lathe. The traditional standard tool rest generally needs the tool shank to extend outwards to match with subsequent machining operation when the longer inner diameter is machined or the tool cutting amount is increased, the conditions of insufficient rigidity of the tool shank, breakage of the tool shank and the like are easily caused in the long-term use process, meanwhile, the machining quality of a machined workpiece can be greatly influenced, the production efficiency and the product quality are reduced, and therefore the traditional tool rest is difficult to efficiently and high-quality match with tools to complete machining production in the use process.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the technical scheme that one of above-mentioned technical problem adopted and be: the utility model provides a novel compound knife rest of numerical control merry go round machine, includes a knife rest body, is equipped with a plurality of center apopore on knife rest body's outer terminal surface, the other end of each center apopore by knife rest body's outer end lateral wall is worn out, and the terminal surface center department of the outer end support body of knife rest body is equipped with the circle handle that is used for placing the circle handle of a knife and places the space, places the space at the circle handle of a knife both sides and is equipped with the square handle that is used for placing the side handle of a knife respectively and places the space, two side handles of a knife and places on the outer end support body of the knife rest body of space both sides and be equipped with a plurality of along its length direction interval respectively and compress tightly the screw hole, compress tightly the.

Preferably, the two square tool shank placing spaces are used for placing tool shanks with different sizes.

Preferably, the four corners of the outer end frame body of the tool frame body are all set to be arc curved surfaces.

The beneficial effects of the utility model are embodied in: 1. the tool rest is an integrated tool rest, compared with a square structure outside the traditional tool rest, the tool rest cannot penetrate into an inner hole with a smaller inner diameter of a workpiece, the outer ring of the composite tool rest in the application adopts an arc structure, when the inner hole is machined, the tool shank does not need to extend out too long, the outer end of the tool rest body directly drives the tool shank to enter the inner hole of the workpiece for machining, the tool shank is prevented from extending too long, the stability and the service life of the tool shank are improved, the tool consumption and feeding can be increased, and the production efficiency and the product quality are improved; meanwhile, the corners at the outer end of the tool rest are arc-shaped, so that the stress concentration of the corners of the tool can be effectively eliminated, and the overall structural strength of the tool is ensured.

2. In addition, the composite tool rest can simultaneously compound multiple tool shanks, so that the tool turret switching time is shortened, the tool arrangement capacity is enlarged compared with the traditional single tool rest, multiple tool shanks can be compatible, and the existing tool rest dismounting time is shortened.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-4, a novel numerical control vertical lathe composite tool rest comprises a tool rest body 1, wherein a plurality of central water outlets 2 are formed in the outer end face of the tool rest body 1, the other end of each central water outlet 2 is penetrated out from the outer end side wall of the tool rest body 1, a circular tool shank placing space 3 for placing a circular tool shank is formed in the end face center of an outer end frame body 101 of the tool rest body 1, square tool shank placing spaces 4 for placing a square tool shank are formed in the two sides of the circular tool shank placing space 3 respectively, a plurality of pressing wire holes 5 are formed in the outer end frame body 101 of the tool rest body 1 on the two sides of the circular tool shank placing space 3 and the two square tool shank placing spaces 4 respectively along the length direction at intervals, and the pressing wire holes 5 are used for screwing and abutting against a screw to position the tool shank placed in the pressing wire holes.

A plurality of that this application set up compresses tightly screw hole 5 and can select handle of a knife male length as required to can satisfy processing operation requirement again effectively when guaranteeing handle of a knife bulk strength.

The purpose of the central water outlet hole 2 is mainly to introduce cooling liquid in the processing process to ensure the cooling of the cutter and the processing workpiece.

Preferably, the two square tool shank placing spaces 4 are used for placing tool shanks with different sizes. The compound knife rest can compound many handle of a knife simultaneously, reduces the tool turret switching time, compares traditional single knife rest and has enlarged row sword capacity, can compatible multiple handle of a knife simultaneously, more reduces current knife rest dismantlement time.

Preferably, the four corners of the outer end frame body 101 of the tool frame body 1 are all provided with arc curved surfaces 6. The outer end corner of the knife rest adopts the circular arc, so that the stress concentration of the corner of the knife can be effectively eliminated, and the integral structural strength of the knife 7 is ensured. The composite knife rest outer ring in the application adopts the circular arc structure, and when the hole is processed, the knife handle does not need to stretch out the overlength, and the 1 outer end of the knife rest body can be directly taken the knife handle to enter the inner hole of the workpiece for processing, so that the knife handle is prevented from stretching out too long, the stability and the service life of the knife handle are increased, the knife eating amount can be increased, the feeding is realized, and the production efficiency and the product quality are improved.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification; to those skilled in the art, any alternative improvements or changes made to the embodiments of the present invention are all within the scope of the present invention.
