Abstract
The utility model relates to a zero locating device on a dynamic tool apron, which comprises a shell, a main shaft, a lining and a spring, wherein the main shaft is arranged in the shell; the lining is arranged on the main shaft; the lining is provided with a bulge; the shell is provided with a groove; the bulge and the groove are matched with each other to serve as a zero locating structure; the bulge can move relatively to the groove, and the spring supports the upper end surface of the lining. When the tool apron is used, the zero locating structure is in the nonworking state, and the main shaft rotates; when the tool apron stops working, the zero locating structure works, and the bulge is stuck in the groove to prevent the main shaft from rotating to take the angle locating function. In the use process of the dynamic tool apron provided with the zero locating device, the influence of the damage on the dynamic tool apron because the main shaft of the tool apron is not matched with an engaging and disengaging gear due to the fact that the main shaft is disturbed by external interference can be effectively avoided, and the service life of the tool apron is prolonged.
Description
Technical field
The utility model relates to a kind of zero-point positioning device that is used on the dynamic tool apron.
Background technology
Power cutter tower is made up of cutter tower body and cutterhead, and cutterhead is installed on the cutter tower body can carry out gyration.On the cutterhead some dynamic tool aprons can be installed, when cutterhead rotates to assigned address, be installed in tool rest on the relevant position and link to each other with power source by arrangement of clutch and realize the gyration of tool rest.
The rotary power of power source is delivered on the rotary main shaft of tool rest by arrangement of clutch.Arrangement of clutch comprises a cover with circumferential tooth, and when the tooth on tooth that puts and the tool rest main shaft meshed, power source can drive the tool rest main axis rotation; In the time of the two disengaging, moving knife seat main shaft stops operating.
For the dynamic tool apron of inferred-zero positioning function, when the tool rest main shaft after turning over certain angle under the external disturbance, the just difficult engaged transmission that realizes arrangement of clutch and tool rest main shaft; In the engagement of the main shaft of arrangement of clutch and tool rest, but when not guaranteeing certain axial insertion depth, also cause the damage of tooth on the tool rest main shaft easily.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provided a kind of cooperation dynamic tool apron to use, and had angle positioning function, thus the zero-point positioning device of protection dynamic tool apron main shaft.
The purpose of this utility model is achieved through the following technical solutions: the zero-point positioning device on a kind of dynamic tool apron, it is characterized in that: it is made up of housing, main shaft, lining and spring, main shaft is installed in the housing, lining is installed on the main shaft, be provided with a projection on lining, housing is provided with a groove, and the two cooperatively interacts as the zero-point positioning structure, projection can relatively move between groove, and spring withstands on the upper surface of lining.
Have keyway on main shaft and lining, lining can move axially in the main shaft upper edge, and together rotation.
The beneficial effects of the utility model: the utility model adopts said structure, and main shaft is installed in the housing, realizes rotatablely moving.Axially displaceable lining is installed on the main shaft, connects with main shaft by spline and together rotates.Spring withstands on the upper surface of lining, for lining provides pretightning force.Lining and housing are provided with the zero-point positioning structure, are a projection on the lining, are a groove on the housing, and projection can relatively move between groove.When tool rest used, the zero-point positioning structure was in off working state, main axis rotation; When tool rest was stopped using, zero-point positioning arrangement works, projection were stuck in and stop main axis rotation in the groove, played angle positioning function.The dynamic tool apron that is equipped with this zero-point positioning device in use can effectively be avoided because the tool rest main shaft is mismatched by external disturbance corner and arrangement of clutch, and then the influence that damages of the dynamic tool apron that causes, the service life of prolongation tool rest.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Zero-point positioning device on a kind of dynamic tool apron is made up of housing 1, main shaft 2, lining 4 and spring 3, and main shaft 2 is installed in the housing 1, and can rotate along the X-X axle in housing 1.Have main shaft keyway 2d, lining keyway 4d on main shaft and lining, lining 4 is installed on the main shaft 2, make lining 4 can be on main shaft 2 vertically (X-X axle) move, and can together rotate with main shaft 2.Be provided with a projection 5 on lining, housing is provided with a groove 6, and the two cooperatively interacts as the zero-point positioning structure, and projection 5 can relatively move 6 of grooves, and spring 3 withstands on the upper surface 4e of lining 4.
Rotatablely move and be delivered on the main shaft 2 by the engagement of power source by keyway on the arrangement of clutch and main shaft keyway 2d.The end that acts on lining 4 when clutch impels lining 4 to move along main shaft 2 axis X-X, and when the end face 5b of lining projection reached as shown in Figure 3 the position when crossing the end face 1a of housing 1, main shaft 2 can rotate freely.In the process of clutch and lining 4 disengagings, the 4e place, upper surface that the pretightning force of cylindrical spring 3 acts on lining impels lining 4 to move along the X-X direction of principal axis, when the 1a face that is positioned at the 5a face of the projection 5 on the lining and housing 1 is fitted, move axially and stop, this structure can prevent that lining 4 from skidding off housing 1.
The dormant state of dynamic tool apron as shown in Figure 2, the zero-point positioning function of dynamic tool apron is in work structuring, and the projection 5 on the lining is stuck in the groove 6 of shell 1, fits in the 5c face of projection 5 and the gap of groove 6, limited the rotation of main shaft 2, realized main angle positioning function axle 2.
The user mode of dynamic tool apron as shown in Figure 3, the zero-point positioning function is in the inoperative structure, power source drives the cutting movement that main shaft 2 can rotate and then realize cutter by clutch.
