Abstract
The utility model discloses a boring cutter bar, which comprises a boring cutter bar body and a connecting joint. The end of the boring cutter bar body is dismountably and fixedly connected with the connecting joint through screw threads. A cutter trough for assembling the boring cutter and a screw nail which is corresponding to the cutter trough and is used for fixing the boring cutter are arranged on the connecting joint. The outer circumferential surface of the connecting joint is provided with a standstill locking cooperation structure which is convenient for a dismantling tool to rotate the connecting joint. By using the boring cutter bar, the cutter can be replaced conveniently and quickly. When the cutter is replaced, the outer circumferential surface of the connecting joint is provided with the standstill locking cooperation structure which is convenient for the dismantling tool to rotate the connecting joint, an operator can complete the cutter replacement work by dismounting the connecting joint by using the dismantling tool, and replacing with a novel connecting joint which has adjusted the dimension already, thereby improving boring processing efficiency. The boring cutter bar has simple structure, uses less components and parts, and saves manufacturing cost.
Description
Technical field
The utility model relates to the boring processing technique field, particularly a kind of boring cutter bar.
Background technology
At the use boring cutter boring is carried out in the aperture and added man-hour, because pore size difference, need frequent change different knife bar and cutter, becoming sleeve boring cutter whenever to change a cutter all must get off whole cutter hub connection taper shank together from machine tool chief axis, change into another set ofly again, tool changing work is heavy, and labor strength is bigger, the waste working time, operating efficiency is told somebody what one's real intentions are.
The utility model content
The purpose of this utility model provides a kind of simple in structure, tool changing boring cutter bar fast and easily.
For achieving the above object, the utility model adopts following technical scheme: a kind of boring cutter bar, comprise boring cutter bar body and connector, the end of described boring cutter bar body is by the removable connector that is fixed with of screw thread, this connector is provided with cutter groove and the screw that be used for fixing boring cutter corresponding with the cutter groove that is used to assemble boring cutter, the outer peripheral face of described connector be provided be convenient to that dismantling device is rotationally connected only revolve fit structure.
The described fit structure that only revolves is to be arranged at the dismantling device groove that being used on the outer peripheral face of connector cooperates with dismantling device.
The described fit structure that only revolves is the reticulate pattern that is arranged on the outer peripheral face of connector.
The described fit structure that only revolves is to be arranged at the dismantling device hole that being used on the outer peripheral face of connector cooperates with dismantling device.
Described dismantling device hole is distributed on the outer peripheral face of connector.
Adopt the utility model boring cutter bar can realize conveniently tool changing, during tool changing, the connector outer peripheral face be provided be convenient to that dismantling device is rotationally connected head only revolve fit structure, the operator can unload connector by using dismantling device, change the connector of new modulated good size and promptly finish tool changing work, thereby can improve the boring working (machining) efficiency.The utility model is simple in structure, and used parts are less, saves production cost.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, a kind of boring cutter bar, comprise boring cutter bar body 1, in the end of boring cutter bar body 1 by the removable connector 2 that is fixed with of screw thread, corresponding end on boring cutter bar 1 body is extended with outer peripheral face and processes threaded step axle, the corresponding end of connector 2 is provided with and the corresponding screwed hole of step axle, the outer peripheral face away from an end of boring cutter bar body of connector 2 is provided with the cutter groove 4 that is used to install cutter head, be installed with the trip bolt 3 that is used for fastening cutter head in the screwed hole of on the end face of connector 2, offering, screwed hole communicates with the cutter groove, trip bolt 3 can go deep in the cutter groove 4, the outer peripheral face of connector 2 be provided be convenient to that dismantling device is rotationally connected head only revolve fit structure, in the present embodiment, only revolve the spanner groove 5 of fit structure for ease of wrench operated, spanner groove 5 can be processed by milling machine, and dismantling device is a spanner class dismantling device.
During concrete enforcement, the fit structure that only revolves on the connector 2 can be the reticulate pattern that is used to increase frictional force that is provided with on the outer peripheral face of connector, and this moment, dismantling device was a spanner class dismantling device.
During concrete enforcement, the fit structure that only revolves on the connector 2 can be the dismantling device hole that cooperates with dismantling device, this moment, dismantling device was and the bar class dismantling device of tooling hole inserting, can not make connector dislocation occur during for the assurance dismounting, and the dismantling device hole should be distributed on the outer peripheral face.
Only revolve fit structure by being arranged on the connector in the utility model,, improved knife bar and changed speed, saved non-cutting time by the direct dismounting connector of dismantling device.
