Abstract

The utility model discloses a machining tool which comprises a base, a machine head and a working platform, wherein the machine head and the working platform respectively move relative to the base; the machining tool further comprises a rack which is fixed on the machine head; the rack is in transmission connection with a first gear; a first rotating shaft is fixedly connected with the first gear and a second gear; the second gear is in transmission connection with a third gear; one end of a second rotating shaft is fixed with the third gear; the other end of the rotating shaft extends into a screw hole in the working platform; the second rotating shaft is provided with a thread which is matched with the screw hole; and a fixing plate which is fixed relative to the base is connected with the second rotating shaft in a sleeving manner so as to stop the third gear from moving close to the working platform in the axial direction. Therefore, the machine head and the working platform can move synchronously without adding any machine, and repeated machining is prevented.

Description

A kind of machining tool

Technical field

The utility model relates to a kind of machining tool.

Background technology

The process of gear is used milling machine, cutter for milling machines is mainly used in thinning the teeth groove of gear, it is linear that the route that the cutter of milling machine is passed by is, the problem that prior art exists is: cutter is reciprocating according to projected route, and the contact point of cutter and teeth groove is less than normal, can not once finish, otherwise, not only because resistance is excessive may damage cutter, process also defectively, demand improvement urgently.

The utility model content

For the problem that prior art exists, the purpose of this utility model is to propose a kind of machining tool, and not needing to add any machinery can be so that head and workbench synchronous operation prevents from repeating processing.

For reaching this purpose, the utility model by the following technical solutions:

A kind of machining tool, comprise base, head, workbench, head and workbench all can move with respect to base, also comprise the tooth bar that is fixed on the head, rack-driving connects the first gear, the first rotating shaft is fixedly connected with the first gear and the second gear, the second gear drive connects the 3rd gear, the second rotating shaft one end is fixed the 3rd gear, the other end stretches into the screw that is opened in workbench, the second rotating shaft is provided with the screw thread that cooperates with screw, and the fixed head fixing with respect to position base is socketed the second rotating shaft to stop the 3rd gear driving shaft to close workbench.Tooth bar overlaps the first gear near an end of workbench, and the other end is rotationally connected head.

Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:

The utility model is in actual process, and when head machines, workbench is moved, when reprocessing, the Working position of cutter changes, and does not duplicate processing, the head moving belt moves movable workbench, and the frequency that both move is consistent, does not add machinery and can make the two synchronous.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:

Embodiment 1

A kind of machining tool is proposed, comprise base 1, head 2, workbench 3, head 2 and workbench 3 all can be with respect to base 1 motions, also comprise the tooth bar 4 that is fixed on the head 2, tooth bar 4 first gear 5 that is in transmission connection, the first rotating shaft 11 is fixedly connected with the first gear 5 and the second gear 6, the second gear 6 the 3rd gear 7 that is in transmission connection, the second rotating shaft 9 one ends are fixed the 3rd gear 3, the other end stretches into the screw 10 that is opened in workbench 3, the second rotating shaft 9 is provided with the screw thread that cooperates with screw 10, and the fixed head 8 fixing with respect to base 1 position is socketed the second rotating shaft 9 to stop the 3rd gear 7 driving shafts to close workbench 3.Tooth bar 4 overlaps the first gear 5 near an end of workbench 3, and the other end is rotationally connected head 2.

When head 2 advances to workbench 3 directions, tooth bar 4 will drive the first gear 5 and rotate, the first gear 5 drives the second gear 6, the second gear 6 drives the 3rd gear 3, the 3rd gear 3 rotates, the second fixing with it rotating shaft 9 is rotated, because the second rotating shaft 9 is provided with the screw thread that cooperates with screw 10, and fixed head 8 stops the 3rd gear 7 driving shafts to close workbench 3, so that workbench 3 will be initiatively near the 3rd gear 7, after head 2 machined, workbench 3 moved, during head 2 reprocessing, the Working position of cutter changes, and can not duplicate processing, moves by the moving workbench 3 of the moving belt of head 2, both travel frequencies are also consistent, do not add other machineries and can reach that the two is synchronous.

The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
