Abstract
The utility model relates to a mechanical high-speed electric spindle draw bar component, in particular to a draw bar mechanism for providing a spindle broach component with broach force and cleaning the inside of a spindle by airflow. A disc spring (4) is disposed in the middle of a draw bar body (1). A slide bush (5) is arranged in the middle of the disc spring (4). A support pad (6) is disposed at the front of the draw bar body (1). The front end of the draw bar body (1) is covered with a pull claw (7). An adjusting washer (8) is disposed in an inner cavity of the pull claw (7). The upper end of the adjusting washer (8) is abutted to the front end of the draw bar body (1). The draw bar component guarantees rotation precision of a mandrel, has lower vibration, is more suitable for adjusting the rotating spindle and is higher in precision of controlling the broach force.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of pull bar and building block thereof of broach force being provided for the main spindle broach assembly.
Background technology
At existing main shaft pull bar, the fitness of itself and rotating shaft is not high, so cause the entire mechanism vibrations through regular meeting, hinders main shaft can not improve rotating speed even cisco unity malfunction, and in addition, broach force control is inaccurate, makes the cutter loading and unloading go wrong easily.
Summary of the invention
The utility model relates to a kind of mechanical high-speed electricity main shaft rod assembly, and it has solved deficiency of the prior art.
The utility model technical solution is to comprise pull bar main body 1, gland 2, axle core 3, pulling claw 7, handle of a knife 9, the middle part that it is characterized in that pull bar main body 1 is provided with dish spring 4, the middle part of dish spring 4 is provided with sliding sleeve 5, and the front portion of pull bar main body 1 is provided with lip block 6, and the front end of pull bar main body 1 is coated with pulling claw 7, the inner chamber of pulling claw 7 is provided with adjusting washer (disk) 8, and the front end face of the upper surface of adjusting washer (disk) 8 and pull bar main body 1 offsets.
Gland screw threads for fastening of the present utility model is on the axle core, and generation dish spring pretightning force, and adjusting washer (disk) is contained in the pulling claw, can change the height of adjusting washer (disk), thereby regulates broach force.In rod assembly when work,, pull bar moves down under the external force effect being subjected to, the compression of dish spring, and sliding sleeve, pulling claw move down, because axle in-core hole increases, the calvus of pulling claw opens under elastic reaction, and it is big that the calvus endoporus becomes, and the promotion handle of a knife, handle of a knife comes off thereupon, realizes unloading the cutter process; When handle of a knife is installed, handle of a knife is installed in the calvus endoporus, remove external force, pull bar and pulling claw move up under the effect of dish spring, and the tension handle of a knife, realize the mounting cutter process, pull bar and adjusting washer (disk) have passage, can be by external source of the gas, portion provides air-flow to the axle in-core, and the dust with axle in-core portion when unloading cutter or dress cutter blows clean.
Advantage of the present utility model is:
1, adopt the dish spring to produce broach force, the distortion of dish spring is little, and broach force is big and stable, is conducive to adapt to electric main shaft and rotates at a high speed;
2, change the height of adjusting washer (disk), can obtain different broach forces with a dishful of spring group, also can be identical down at broach force, suitable different dish spring group has reduced the production and processing difficulty;
3, by external source of the gas, can provide air-flow to axle in-core portion, cleaning axle core improves service life;
4, by external pressure, can realize the automatic tool changer of handle of a knife, convenient to use;
5, pull bar, sliding sleeve have one deck high-abrasive material, reduce the vibration that pull bar produces when rotating at a high speed, are conducive to adapt to electric main shaft and rotate at a high speed;
6, this apparatus structure compactness is fit to high rotating speed, high accuracy, the low characteristic of vibrating, and can be widely used in various high-speed electric main shaft tool-broaching mechanisms.
Description of drawings
Fig. 1 is organigram of the present utility model.
The specific embodiment
According to shown in Figure 1, the utility model is in existing pull bar main body 1, gland 2, axle core 3, pulling claw 7, on the basis of handle of a knife 9, the middle part of pull bar main body 1 is provided with dish spring 4, and the middle part of dish spring 4 is provided with sliding sleeve 5, the front portion of pull bar main body 1 is provided with lip block 6, the front end of pull bar main body 1 is coated with pulling claw 7, and the inner chamber of pulling claw 7 is provided with adjusting washer (disk) 8, and the front end face of the upper surface of adjusting washer (disk) 8 and pull bar main body 1 offsets.
