Abstract
The utility model discloses a grinding cutter bar, which belongs to the technical field of grinding equipment and comprises an upper section cutter bar, wherein the lower end of the upper section cutter bar is fixedly connected with a middle section cutter bar, the lower end of the middle section cutter bar is fixedly connected with a lower section cutter bar, a clamping jaw clamping groove is formed in the middle of the middle section cutter bar, and a plane notch is formed in the clamping jaw clamping groove on the rod wall of the middle section cutter bar. When the grinding disc is installed, the wrench firstly extends into the clamping jaw clamping groove, the grinding cutter bar is limited and fixed by the wrench, then the grinding disc to be installed is sleeved on the lower cutter bar, finally the lower pressing plate is connected with the lower cutter bar through threads, the grinding disc is fixed on the grinding cutter bar through the mutual matching of the lower pressing plate and the middle cutter bar, and the grinding disc and the grinding cutter bar can be quickly connected through the mode.
Description
Technical Field
The utility model relates to the technical field of polishing equipment, in particular to a grinding cutter bar.
Background
The common grinding cutter bar needs more parts to be combined during installation, and is loose in fit before the lower pressing plate is screwed up, so that dislocation is easy to occur, and time and labor are wasted in installation. When dismantling, because the tight power of self that produces among the grinding process, the clamp plate can block very tightly, when dismantling with strength, the condition that each part scatters appears easily, and the step is more when consumptive materials such as abrasive disc, emery wheel are changed to this kind of mode, wastes time and energy.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a grinding tool holder to solve the above problems of the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a grinding cutter arbor, includes the upper segment cutter arbor, the lower extreme fixedly connected with middle section cutter arbor of upper segment cutter arbor, the lower extreme fixedly connected with hypomere cutter arbor of middle section cutter arbor, the middle part of middle section cutter arbor is equipped with the clamping jaw draw-in groove, it is equipped with the plane breach to lie in clamping jaw draw-in groove inside on the pole wall of middle section cutter arbor.
As a further aspect of the utility model, the diameter of the middle section of the blade is larger than the diameter of the upper section of the blade.
In yet a further aspect of the utility model, the diameter of the middle section shaft is larger than the diameter of the lower section shaft.
As a further scheme of the utility model, the rod wall of the lower cutter rod is provided with threads.
Compared with the prior art, the utility model has the beneficial effects that:
1. when the grinding disc is installed, the wrench firstly extends into the clamping jaw clamping groove, the grinding cutter bar is limited and fixed by the wrench, then the grinding disc to be installed is sleeved on the lower cutter bar, finally the lower pressing plate is connected with the lower cutter bar through threads, the grinding disc is fixed on the grinding cutter bar through the mutual matching of the lower pressing plate and the middle cutter bar, and the grinding disc and the grinding cutter bar can be quickly connected through the mode.
2. The utility model has the characteristics of simple structure and few parts, and can quickly carry out the installation and the disassembly of the grinding sheet.

Fig. 2 is a plan view of a grinding tool bar.
Fig. 3 is a plan view of a grinding tool bar.
In the figure: 1. an upper section cutter bar; 2. a middle section cutter bar; 3. a clamping jaw clamping groove; 4. a planar notch; 5. a lower cutter bar; 6. and a limiting table.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, in an embodiment of the present invention, a grinding cutter bar includes an upper cutter bar 1, a middle cutter bar 2 is fixedly connected to a lower end of the upper cutter bar 1, a lower cutter bar 5 is fixedly connected to a lower end of the middle cutter bar 2, the upper cutter bar 1, the middle cutter bar 2 and the lower cutter bar 5 are integrally formed, a diameter of the middle cutter bar 2 is larger than a diameter of the upper cutter bar 1, a diameter of the middle cutter bar 2 is larger than a diameter of the lower cutter bar 5, a clamping jaw slot 3 is disposed in a middle portion of the middle cutter bar 2, a plane notch 4 is disposed inside the clamping jaw slot 3 on a bar wall of the middle cutter bar 2, the grinding cutter bar is conveniently clamped by a wrench through the plane gap 4, the lower end of the middle section cutter bar 2 is provided with a limit table 6, the grinding disc arranged on the lower section cutter bar 5 and the middle section cutter bar 2 have a certain distance through the limiting table 6, so that the grinding disc is prevented from contacting with the clamping jaw, and threads are arranged on the rod wall of the lower section cutter bar 5.
The working principle of the utility model is as follows:
when the grinding sheet is installed, a wrench is firstly stretched into a clamping jaw clamping groove 3, a grinding cutter bar is limited and fixed by the wrench, then the grinding sheet to be installed is sleeved on a lower section cutter bar 5, finally a lower pressing plate is connected with the lower section cutter bar 5 through threads, and the grinding sheet is fixed on the grinding cutter bar by the mutual matching of the lower pressing plate and a middle section cutter bar 2;
when the grinding cutter bar is fixed, the clamping jaw clamping groove 3 is aligned to the jaw tip of the clamping jaw in the tool magazine, then the grinding cutter bar is pushed to clamp the clamping jaw in the clamping jaw clamping groove 3, so that the whole grinding cutter bar is fixed, and then the grinding cutter bar is connected with automatic equipment;
when the grinding disc needs to be replaced, the grinding cutter rod is taken down from the automatic equipment, then the grinding cutter rod is taken out from the tool magazine, and finally the pressing plate is detached to take down the grinding disc.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
