Abstract
The utility model relates to a cutter bar pressing device for a deep hole lathe, and belongs to the technical field of the design of a cutter bar fixing mechanism on the lathe. The cutter bar pressing device for the deep hole lathe comprises a cutter bar clamping seat and is characterized in that a through hole used for being penetrated by a cutter bar is formed in the cutter bar clamping seat, a cutter bar clamping piece is arranged in the through hole, and a tight ejection mechanism is arranged on the cutter bar clamping seat corresponding to the cutter bar clamping piece. The cutter bar pressing device for the deep hole lathe is simple in structure, due to the fact that the cutter bar clamping piece is used, the contacting area between the cutter bar clamping piece and the cutter bar can be increased, friction is greatly improved in the using process, therefore, the cutter bar can be well fixed under the action of the tight ejection mechanism, and the cutter bar can be effectively guaranteed to not rotate when products are machined.
Description
Technical field
The utility model relates to a kind of for the knife bar hold down gag on the deep hole lathe, belongs to the design field of knife bar fixed mechanism on the lathe.
Background technology
At present, when the deep hole lathe was worked, the knife bar on its lathe whether relatively lathe was completely fixed very importantly, mainly is because on the knife bar cutter is installed, and will damage cutter if knife bar rotates.And clamping mode commonly used is: utilize screw thread tension tapering collet, knife bar is compressed.Adopt this method when converted products, the phenomenon that can not compress fully occurs sometimes, especially when the converted products material is really up to the mark, be easy to make knife bar to rotate, thus the damage cutter.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of it is simple in structure for the knife bar hold down gag on the deep hole lathe, guaranteed that knife bar can not rotate when converted products.
Described in the utility model for the knife bar hold down gag on the deep hole lathe, comprise the cutter bar clamping seat, it is characterized in that: offer the through hole that passes for knife bar at the cutter bar clamping seat, be provided with knife bar and step up sheet in through hole, corresponding knife bar steps up sheet and is provided with jacking mechanism at the cutter bar clamping seat.
When compressing knife bar, knife bar is passed from through hole, add knife bar and step up sheet, then utilize jacking mechanism effect knife bar to step up sheet with cutter bar clamping.Adopt knife bar to step up that sheet can increase and knife bar between contact area, frictional force improves greatly during use, thereby can well knife bar be fixed under the effect of jacking mechanism.
The preferred described jacking mechanism of the utility model comprises fastening screw, and corresponding fastening screw is provided with the screwed hole that matches with it at the cutter bar clamping seat, and fastening screw withstands on knife bar by screwed hole and steps up the sheet outer surface.
When practical application, jacking mechanism can also be selected hydraulic cylinder, pneumatic cylinder or other mechanical jacking mechanism.
Wherein to step up sheet be two mutual clip-on half camber structures to the preferred described knife bar of the utility model, and arbor holder is between the two halves camber.
Adopt said structure, can guarantee when guaranteeing to compress knife bar that effectively knife bar can not be out of shape.
Compared with prior art, the utlity model has following beneficial effect:
Pass through the utility model, it is simple in structure because adopt knife bar to step up that sheet can increase and knife bar between contact area, frictional force improves greatly during use, thereby under the effect of jacking mechanism, can well knife bar be fixed, guarantee that effectively knife bar can not rotate when converted products.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Among the figure: 1, fastening screw 2, knife bar step up sheet 3, knife bar 4, cutter bar clamping seat.
The specific embodiment
Below the utility model is described in further detail by specific embodiment; but not in order to limit the utility model; all within the present invention spirit and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
As shown in Figure 1 and Figure 2, be used for the knife bar hold down gag on the deep hole lathe, comprise cutter bar clamping seat 4, offer the through hole that passes for knife bar 3 at cutter bar clamping seat 4, be provided with knife bar and step up sheet 2 in through hole, corresponding knife bar steps up sheet 2 and is provided with jacking mechanism at cutter bar clamping seat 4.
In the present embodiment, described jacking mechanism comprises fastening screw 1, and corresponding fastening screw 1 is provided with the screwed hole that matches with it at cutter bar clamping seat 4, and fastening screw 1 withstands on knife bar by screwed hole and steps up sheet 2 outer surfaces; It is two mutual clip-on half camber structures that described knife bar steps up sheet 2, and knife bar 3 is clipped between the two halves camber.
When compressing knife bar 3, cutter bar clamping seat 4 is installed on the lathe guide rail, knife bar 3 passes from through hole, the knife bar of adding two mutual clip-on half cambers steps up sheet 2, then tighten fastening screw 1, make its effect knife bar step up sheet 2 knife bar 3 is clamped, can carry out further work.
Claims (3)
1. knife bar hold down gag that is used on the deep hole lathe, comprise cutter bar clamping seat (4), it is characterized in that: offer the through hole that passes for knife bar (3) at cutter bar clamping seat (4), be provided with knife bar and step up sheet (2) in through hole, corresponding knife bar steps up sheet (2) and is provided with jacking mechanism at cutter bar clamping seat (4).
