Abstract
The utility model relates to a claw pulling mechanism of a ball high-speed electric main shaft, in particular to a cutter changing mechanism of a main shaft broaching component. A connecting screw thread (1) is arranged on the inner wall of a connecting part (8); symmetrical detaching flat positions (2) are arranged around the outer wall of the connecting part (8); an annular lubricating groove (3) is formed on the outer wall of the lower part of the connecting part (8); an adjusting cushion sheet mounting position (4) is arranged on the inner wall of the connecting part (8) corresponding to the lubricating groove (3); a dust blowing hole (5) is formed on the lower part of the adjusting cushion sheet mounting position (4); a slide face (6) is arranged at a step on the lower part of a conical claw (9); and a broaching conical face (7) is arranged on the inner wall of the lower end part of the conical claw (9). The claw pulling mechanism of the ball high-speed electric main shaft has the advantages that: the structure is firm, the assembly is accurate, the claw pulling mechanism is not easy to lock, external objects are prevented from entering a main shaft, a broaching force is uniform and stable, and the claw pulling mechanism is convenient to popularize and apply.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of cutter-exchange mechanism of main spindle broach assembly.
Background technology
In the prior art, the pulling claw mechanism of main shaft is stuck easily when tool changing up and down, and the broach force of pulling claw is unbalanced, firm, causes the main shaft work degree of accuracy low, and damages easily.
Summary of the invention
The utility model relates to a kind of pulling claw mechanism of ball high-speed electric main shaft, and its overall structure is firm, and assembling accurately is difficult for stuckly, prevents that foreign object from entering main shaft, and broach force equilibrium, firm is convenient to promote and use.
The utility model technical solution is to be provided with the pulling claw main body at existing main shaft axle in-core, connecting portion (8) is arranged at pulling claw main body top, the pulling claw bottom is on the basis of taper pawl (9), the utility model is provided with connecting thread (1) particularly in connecting portion (8) inwall, be provided with the flat position of dismounting (2) of symmetry around the outer wall of connecting portion (8), the bottom outer wall of connecting portion (8) is provided with ring-type lubrication groove (3), the inwall of the pairing connecting portion of lubrication groove (3) (8) is provided with regulates pad installation position (4), and the bottom of regulating pad installation position (4) is provided with drifting dust hole (5); Be provided with sliding surface (6) at the lower step place of taper pawl (9), the bottom inwall of taper pawl (9) is provided with the broaching tool conical surface (7).
More than connecting portion (8) lower flat of pulling claw described in the utility model bottom be distributed with six lobe taper pawls (9).
The lower step place of taper pawl described in the utility model (9) is provided with sliding surface (6).
The utility model is when the tool changing of ball high-speed electric main shaft, and pulling claw is under the round pulling of pull bar, and six lobe taper claws are free hypertonic of while under the restriction of axle in-core hole wall, makes broaching tool conical surface contact handle of a knife annex unload the action of cutter broaching tool.
Advantage of the present utility model is:
1, design thread connecting mode between connecting thread and pull bar in the pulling claw, be convenient to assembling and help each part processing again, it is firm to connect installation back overall structure;
2, other surfaces of pulling claw can not damaged in the flat position of design in the pulling claw when being convenient to the installation locking of pulling claw and assembling;
3, specialized designs has lubrication groove in the pulling claw, is difficult for stuck when pulling claw is moved up and down in axle in-core hole;
4, regulate the pad installation position in the pulling claw, adjustable shim is seated pulling claw in installation process;
5, drifting dust hole in the pulling claw, blow gas cleaning pulling claw and by the tool changing handle during main shaft tool changing, and stop extra-organismal sewage, cutting swarf, gas etc. to enter main shaft;
6, well-designed slip curved surface in the pulling claw, make pulling claw in axle in-core hole up and down hypertonic when motion slide freely smooth and easyly, be difficult for scratching, stuck etc.;
7, the broaching tool conical surface of scientific and reasonable design in the pulling claw, when six lobe taper claw broaching tools, can regulate automatically balanced each claw with obtain best axially, tightening force radially;
8, branch such as pulling claw bottom quilt cutting back forms six claw, making each claw become tapered through innovative technology manufacturing technology and strict processing outwards evenly opens, and maintenance certain deformation rigidity and intensity, add the circular arc transition face design on the claw, make each claw can be evenly, between axle in-core hole, be free to slide hypertonic apace;
9, this pulling claw have cutter changing fast, convenient, safety, dynamically descend advantages such as broach force equilibrium, firm, good rigidly long service life, can be widely used in the tool-broaching mechanism of the electric main shafts of various ball high speed machines.
