Description
Technical field
The utility model relates to taper hole grinder, particularly relates to a kind of portable taper hole grinder.
Background technology
The world today, industrially developed country pays much attention to machine tool industry, unexpectedly develops electromechanical integration, high-precision, efficient, the advanced lathe of high automation mutually, to accelerate the development of industry and national economy.Along with the universalness of Digit Control Machine Tool, its relevant corollary equipment also develops rapidly, wherein just comprises spindle taper hole grinder.Spindle taper hole grinder repeatedly can be repaired damaging main shaft, greatly improves the service life of main shaft.
Current spindle taper hole grinder on the market needs main shaft to disassemble to repair mostly, and this will produce main shaft bearing and pollute and damage, does not accomplish best reparation.If can accomplish not dismantle the reparation that main shaft can complete main shaft, and repair precision and new main shaft very close, that will improve service life and the utilization rate of main shaft greatly.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of portable taper hole grinder.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of portable taper hole grinder, comprise lapping device, described lapping device comprises support and the fuselage with grinding head, and power transmission shaft is connected with fuselage, and described power transmission shaft is linked by the output shaft of belt and motor.
Adjustable positioning mechanism is provided with between described support and motor, described adjustable positioning mechanism comprises the screw being arranged at motor sidewall, also comprise a backstay, one end of described backstay is with the screw thread matched with screw, other end band is fluted, the rear of described support is provided with locating piece, described locating piece is provided with the locating hole coaxial with screw, described locating piece is also provided with the fixing hole vertical with locating hole, described fixing hole place is provided with hold-down screw, and described hold-down screw alignment indentation is fixed.
Described grinding head is connected with power transmission shaft by fixing multi-directional ball or permanent universal joint.
The beneficial effects of the utility model are:
1. safeguarding without the need to pulling down whole main shaft, reducing labour, reduce maintenance cost;
2. the utility model kit structure is simple, and is equipped with a micro-machine, a support and a grinding head, add other accessories, and gross mass, at about 12KG, is transported and carried very convenient, need only the tool box of a 300MM*200MM*100MM just can load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is support, and 2 is fuselage, and 3 is power transmission shaft, and 4 is grinding head, and 5 is belt pulley, and 6 is motor, and 7 is the output shaft of motor, and 8 is belt, and 9 is screw, and 10 is backstay, and 11 is groove, and 12 is locating piece, and 13 is hold-down screw.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1.
A kind of portable taper hole grinder, comprise lapping device, described lapping device comprises support 1 and the fuselage 2 with grinding head 4, and power transmission shaft 3 is connected with fuselage 2, and described power transmission shaft 3 is linked by the output shaft 7 of belt 8 with motor 6.
Portable taper hole grinder of the present utility model, support 1, fuselage 2, motor 6 all can independent disassemblings, therefore, in actual use, if need the taper hole of machining tool main shaft, do not need main shaft to disassemble, support 1, fuselage 2, grinding head 4 can be assembled, after grinding head 4 is aimed at, coupled together by the output shaft of belt 8 with motor 6, by driven by motor, belt transmission, indirectly drives grinding head to rotate and grinds.
Due to slight vibrations can be produced in process of lapping, vibrations will cause error to grinding head, cause taper hole error further, therefore, as one preferred embodiment, adjustable positioning mechanism is provided with between described support 1 and motor 6, described adjustable positioning mechanism comprises the screw 9 being arranged at motor 6 sidewall, also comprise a backstay 10, one end of described backstay 10 is with the screw thread matched with screw 9, other end band fluted 11, the rear of described support 1 is provided with locating piece 12, described locating piece 12 is provided with the locating hole coaxial with screw 9, described locating piece 12 is also provided with the fixing hole vertical with locating hole, described fixing hole place is provided with hold-down screw 13, described hold-down screw 13 alignment indentation 11 is fixed.When grinding head is aimed at, belt installation and debugging are good, when finding accurate abrasion site, by screwed for backstay 10 one end from locating hole insert after and screw 9 tighten, then hold-down screw 13 is adopted to be compressed in locating hole by backstay 10, like this, the relative position between support and motor keeps fixing, substantially reduces mismachining tolerance.
Grinding head 4 is connected with power transmission shaft 3 by fixing multi-directional ball or permanent universal joint.Grinding head is fixed after finding machining angle accurately by fixing multi-directional ball or permanent universal joint, ensure that adjustability and the stability of machining angle.
The utility model kit structure is simple, and is equipped with a micro-machine, a support and a grinding head, add other accessories, and gross mass, at about 12KG, is transported and carried very convenient, need only the tool box of a 300MM*200MM*100MM just can load.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalents utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
