Abstract
The utility model relates to a manual tool-changing mechanism used for a milling machine, which comprises a milling head box (6) with a disc clamping spring. The manual tool-changing mechanism is characterized in that a supporting seat (5) is arranged at the upper part of the milling head box (6), an eccentric shaft (3) is installed on the supporting seat (5), an eccentric wheel (2) is installed on the eccentric shaft (3), a pull rod (1) is installed on the eccentric wheel (2), and the eccentric wheel (2) is in contact with the upper end of the pull rod used for installing the tool tip and positioned in the milling head box (6); an eccentric wheel resetting spring (4) is installed on the eccentric shaft (3), one end of the eccentric wheel resetting spring (4) is propped against the eccentric wheel (2), and the other end of the eccentric wheel resetting spring (4) is propped against the supporting seat (5). The utility model has a series of advantages of simple structure, convenient operation, good reliability, greatly reduced cost of the machine tool, and the like.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of milling machine cutter cutter-exchange mechanism, specifically a kind of milling machine manual tool changing mechanism.
Background technology
The tool-holder compact form of at present general milling machine has two kinds, and the one, bolt nut locking mechanism, another kind are the structures that relies on disk spring tension cutter.The former tool changing operation is more, influences operating efficiency; Latter's tool changing all is to rely on electronic or pneumatic the realization, and complex structure and cost are higher.
Summary of the invention
The purpose of this utility model is at the inconvenience of existing milling machine cutter tool changing clamping, problem that cost is high, designs a kind of simple in structurely, and cost is low, milling machine manual tool changing mechanism easy to use.
The technical solution of the utility model is:
A kind of milling machine manual tool changing mechanism, comprise the milling head box that has dish-shaped fastening spring, it is characterized in that being provided with supporting seat on the top of milling head box, eccentric shaft is installed on the supporting seat, eccentric wheel is installed on the eccentric shaft, pull bar is installed on the eccentric wheel, and the upper end of the pull bar of the installation cutter head in eccentric wheel and the milling head box contacts; The eccentric wheel back-moving spring is installed on eccentric shaft, and an end and the eccentric wheel of eccentric wheel back-moving spring offset, and the other end and supporting seat offset.
The cutter clamping head is installed in the described milling head box, and the upper end that the pull bar of cutter head is installed in the described cutter clamping head contacts with eccentric periphery or offsets with step surface on the eccentric wheel end face.
The beneficial effects of the utility model:
The utility model is simple in structure, and is easy to operate, and good reliability can reduce the lathe cost greatly.Also can be applicable to check in the milling head box assembling process reliability of main shaft assembling.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of milling machine manual tool changing mechanism, comprise the milling head box 6 that has dish-shaped fastening spring, be provided with supporting seat 5 on the top of milling head box 6, eccentric shaft 3 is installed on the supporting seat 5, eccentric wheel 2 is installed on the eccentric shaft 3, manual draw bar 1 is installed on the eccentric wheel 2, and the upper end of the pull bar 7 of the installation cutter head in eccentric wheel 2 and the milling head box 6 contacts; Eccentric wheel back-moving spring 4 is installed on eccentric shaft 3, and an end and the eccentric wheel 2 of eccentric wheel back-moving spring 4 offset, and the other end and supporting seat 5 offset.
Being installed in the upper end that the pull bar 7 of cutter head is installed in the cutter clamping head 8 in the milling head box 6 during concrete enforcement both can contact with the periphery of eccentric wheel 2, the upper end that step surface and pull bar 7 also can be set on eccentric wheel 2 end faces offsets, step surface can be processed to form, and also can form by modes such as soldering projection, bars.
Operation principle of the present utility model is:
When needing tool changing, can make eccentric wheel 2 around axle 3 rotations earlier with pulling moving pull bar 1, the elastic force that eccentric wheel 2 makes the pull bar 7 in the milling head box overcome disk spring moves downward, thereby cutter is unclamped.Releasing lever 1, the disk spring of compression bounce-back originally clamps cutter, and pull bar 1 and eccentric wheel 2 return to the home position under the effect of eccentric wheel back-moving spring 4, finish whole tool changing action.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (2)
