SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a with milling teeth sword firm in connection and with the milling teeth sword difficult milling teeth sword dabber that produces wearing and tearing when assembling.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a gear milling cutter dabber, the dabber is including connecting gradually and coaxial first axis body, the second axle body and the third axis body, and the diameter of first axis body is less than the diameter of the third axis body, and the cross-section of the second axle body is isosceles trapezoid, and the diameter of the second axle body is crescent in the direction of first axis body to the third axis body, and the minimum diameter of the second axle body is greater than the diameter of first axis body, and the maximum diameter of the second axle body is less than the diameter of the third axis body.
Furthermore, a first sealing groove is formed in the joint of the first shaft body and the second shaft body, a second sealing groove is formed in the joint of the second shaft body and the third shaft body, the first sealing groove and the second sealing groove are coaxial with the second shaft body, a limiting ring coaxial with the third shaft body is arranged on the third shaft body, one side end face of the limiting ring and one side end face of the second sealing groove are arranged on the same plane, a positioning notch is formed in the limiting ring, and a positioning protrusion is arranged on the side wall of the first shaft body.
By adopting the technical scheme, the beneficial effects of the utility model are that: the assembly of the mandrel and the gear milling cutter is more convenient, and the abrasion is not easy to generate; when the gear milling cutter is connected with the mandrel, the gear milling cutter is connected with the bearing sleeve and the elastic sealing ring in a matched mode, so that the gear milling cutter is more stable and firm in connection with the mandrel, and the gear milling cutter is not prone to loosening with the mandrel when external force is applied.

Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 5.
A milling cutter mandrel which is firmly connected with a milling cutter and is not easy to wear when being assembled with the milling cutter.
The utility model discloses a concrete implementation scheme: the dabber is including connecting gradually and coaxial first axis body 1, the second axis body 2 and the third axis body 3, and the diameter of first axis body 1 is less than the diameter of third axis body 3, and the cross-section of the second axis body 2 is isosceles trapezoid, and the diameter of the second axis body 2 is crescent in the direction of first axis body 1 to third axis body 3, and the minimum diameter of the second axis body 2 is greater than the diameter of first axis body 1, and the maximum diameter of the second axis body 2 is less than the diameter of third axis body 3.
When the milling cutter 201 is installed on the mandrel, the cross section of the connecting hole 202 on the milling cutter 201 is in an isosceles trapezoid shape, the connecting hole 202 of the milling cutter 201 is sequentially passed through by the first shaft body 1 and the second shaft body 2 on the mandrel, the inner wall of the connecting hole 202 of the milling cutter 201 is butted and attached to the outer wall of the second shaft body 2, and therefore when the milling cutter 201 is installed on the mandrel, friction is not easily generated between the inner wall and the first shaft body 1 and the second shaft body 2, and abrasion is not easily generated when the milling cutter 201 is connected with the mandrel in an assembling mode.
First axis body 1 and the junction of second axis body 2 are opened there is first seal groove 4, the junction of second axis body 2 and third axis body 3 is opened there is second seal groove 5, first seal groove 4 and second seal groove 5 all are coaxial with second axis body 2, be equipped with on the third axis body 3 with the coaxial spacing ring 6 of third axis body 3, the coplanar is arranged in with a side end face of second seal groove 5 to a side end face of spacing ring 6, it has location breach 7 to open on the spacing ring 6, be equipped with location arch 8 on the lateral wall of first axis body 1.
Before the gear milling cutter 201 is installed on the mandrel, an elastic sealing ring 203 is installed, the elastic sealing ring 203 is installed on the mandrel through a second sealing groove 5, when the gear milling cutter 201 is installed on the mandrel, the gear milling cutter 201 is abutted against the elastic sealing ring 203, the elastic sealing ring 203 is abutted against the limiting ring 6, then the other elastic sealing ring 203 is arranged on the mandrel through the first sealing groove 4, the other elastic sealing ring 203 is abutted against the gear milling cutter 201, then the positioning notch 7 on the limiting ring 6 corresponds to the fixing hole 204 on the milling cutter 201, the staple 209 is inserted into the positioning notch and the fixing hole 204 in sequence, the milling cutter 201 and the limiting ring 6 are fixed together, finally the C-shaped bearing 205 is sleeved on the first shaft body 1, the bearing 205 extrudes the other elastic sealing ring 203, the bearing 205 is provided with a positioning hole 208 clamped with the positioning bulge 8, and finally the C-shaped bearing 205 is closed through a screw 206 and a nut 207; the dabber sets up like this, and the spacing ring 6 is fixed a position to milling teeth sword 201, and bearing 205 is fixed to milling teeth sword 201, and two elastic sealing ring 203 increase the pretightning force of milling teeth sword 201 with spacing ring 6 and bearing 205 to make dabber and milling teeth sword 201 be connected more stably firm.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
