The utility model discloses a exquisite cooperation between each part props the adapter inner wall with the inflation cover, produces towards the pulling force with the gravity hammer, pulls down the adapter from the main shaft through the dual function of frictional force and impact force, not only strengthens withdrawal force but also can not produce the damage to the dismantlement part.
Description
Technical Field
The utility model relates to a digit control machine tool maintenance accessory technical field, concretely relates to digit control machine tool spindle adapter extracting tool.
Background
When the numerical control lathe is used daily, the main shaft adapter needs to be frequently detached for maintenance or replacement, but the structure specificity and the high precision of components are difficult to realize by using common tools; and because the internal space of the machine tool is limited, the machine tool can easily collide with other places during the disassembly process by using a common tool, so that the machine tool is not safe and can cause damage to other parts of equipment.
Disclosure of Invention
The utility model aims at overcoming the shortcoming and not enough of prior art, provide a simple structure, convenient to use, dismantle fast, to the little digit control machine tool main shaft adapter extracting tool of equipment damage.
In order to achieve the above purpose, the technical solution of the utility model is that: the utility model provides a digit control machine tool spindle adapter extracting tool which characterized in that: the gravity hammer is sleeved on one end of the adjusting rod, the other end of the adjusting rod is screwed with the expansion sleeve, and the other end of the expansion sleeve is in threaded connection with the taper head.
The gravity hammer is characterized in that a central hole groove is formed in the gravity hammer, one end of the adjusting rod is located in the central hole groove, and the diameter of the central hole groove is larger than or equal to the diameter of the end portion of the adjusting rod and larger than the diameter of an outer hole of the central hole groove.
And a flat opening convenient for clamping tools is arranged on the outer wall of one end, connected with the adjusting rod in a screwing way, of the expansion sleeve.
The utility model discloses a exquisite cooperation between each part props the adapter inner wall with the inflation cover, produces towards the pulling force with the gravity hammer, pulls down the adapter from the main shaft through the dual function of frictional force and impact force, not only strengthens withdrawal force but also can not produce the damage to the dismantlement part.
Drawings
Fig. 1 is a first schematic structural diagram (perspective view) of the present invention.
Fig. 2 is a schematic structural diagram (sectional view) of the present invention.
Fig. 3 is an exemplary view of the present invention.
In the figure: the expansion sleeve comprises an expansion sleeve 1, an adjusting rod 2, a gravity hammer 3, a taper head 4 and a central hole groove 5.
Detailed Description
The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.
Referring to fig. 1-2, a tool for detaching a spindle adapter of a numerically-controlled machine tool comprises an expansion sleeve 1, an adjusting rod 2 and a gravity hammer 3, wherein the gravity hammer 3 is sleeved at one end of the adjusting rod 2, a central hole groove 5 is formed in the adjusting rod 2 and positioned inside the gravity hammer 3, one end of the adjusting rod 2 is positioned in the central hole groove 5, in order to facilitate rotation of the adjusting rod 2, a slotted hole which facilitates adjustment of an inner hexagonal wrench is formed in the end face of the adjusting rod 2 positioned at one end of the central hole groove 5, in order to facilitate free sliding of the gravity hammer 3 on the adjusting rod 2, the diameter of the end part of the adjusting rod 2 of the central hole groove 5 is larger than or equal to the diameter of the main body of the adjusting rod 2, the other end of the adjusting rod 2 is screwed with the expansion sleeve 1, and the outer wall of the end, where the expansion sleeve 1 and the adjusting rod 2 are screwed, is provided with a flat opening which facilitates clamping of the tool, the other end of the expansion sleeve 1 is in threaded connection with the taper head 4.
The utility model discloses during the equipment, earlier pass the regulation pole 2 through the 5 outer hole positions in central hole groove 3 with gravity hammer, then will expand cover 1 and pass through bottom screw hole cover on adjusting pole 2, expand and pass through threaded connection between cover 1 and the tapering head 4, use the spanner at last will expand cover 1 and fix on adjusting pole 2, ensure to adjust pole 2 and rotate around in expanding cover 1 and adjust smoothly, gravity hammer 3 can be adjusting 2 tip positions free slip of pole, so far the equipment is accomplished.
The utility model discloses an application example structure chart refers to fig. 3, when dismantling, arrange tapering head 4 and partial expansion sleeve 1 in the adapter, ensure to put into the degree of depth, fix instrument main part expansion sleeve 1 with the open-ended spanner or with handheld, adjust the position of pole 2 through the allen key, make tapering head 4 extrude the expansion sleeve 1 front end backward, make it take place to deform, prop up the adapter inner wall of installing in the main shaft, later take off open-ended spanner and allen key, hold gravity hammer 3 with the hand, push to behind the expansion sleeve 1 bottom direction after pulling striking regulation pole 2 afterbody backward, after once or many such actions, the adapter breaks away from with the main shaft under the frictional force that produces with expansion sleeve 1 head contact and the impact force that gravity hammer 3 strikes regulation pole 2 afterbody, so far dismantle and accomplish, later reverse regulation pole 2 is adjusted again, make tapering head 4 break away from by extruded expansion sleeve 1, the expansion sleeve 1 is reset at the deformed position and is not contacted with the inner wall of the adapter any more, and the tool can be taken out.
