Description
Technical field
The utility model relates to a kind of machine tool, relates in particular to a kind of provision for disengagement.
Background technology
2030 milling trains are a kind of milling trains with Design of Safety Pin Coupling, and the effect of Design of Safety Pin Coupling is that the rotating torque with the main transmission motor is delivered on the gear-box, rotates thereby drive power transmission shaft.It has self-centering, when excess load operates, can cut off safety pin automatically with characteristics such as protection milling equipment and big motors.Its catcher adopts dry oil lubrication.Two tie points of gear-box both sides adopt circle-arc tooth, can transmit moment of torsion on the one hand, can eliminate on the other hand because the influence of the deflection angle that big motor and reduction box decentraction are brought.
Above-mentioned milling train in use, when needs were checked Design of Safety Pin Coupling or changed, 36 spring catch must pulling down the shaft coupling both sides were to take shaft coupling apart.Wherein reduction box side spring catch is arranged in the blind hole.Fig. 1 has shown the structure that is provided with of shaft coupling reduction box side spring catch.As shown in Figure 1, on shaft coupling body 3, be provided with blind hole, spring catch 1 is located in the blind hole, and fixing by bolt 2.The method of dismounting spring catch is that bolt 2 and spring catch 1 are welded together at present, and then pulls it through the oil cylinder of loosing core.Use this method dismounting spring catch consuming time longer, on average dismantling a spring catch needs 30 minutes; In addition, the spring catch 1 that adopts this mode to pull down all can't re-use with bolt 2, and spring catch that need more renew and bolt have caused waste.
Summary of the invention
The goal of the invention of the utility model provides the provision for disengagement of a kind of blind hole spring catch, and this provision for disengagement can be dismantled spring catch easily, and can significantly reduce the needed time of dismounting spring catch.
According to the foregoing invention purpose, the utility model provides the provision for disengagement of a kind of blind hole spring catch, it comprises:
One columniform pin removal body; Pin removal has a thread segment and a gripper section along its axial direction; Thread segment is provided with external screw thread, and the gripper section has several grippers that evenly are provided with along the circumferential direction of pin removal body, and the end of each gripper all has an outwardly directed convexity;
One plug, it is located in the pin removal body;
One nut, the one of which end is threaded with the thread segment of pin removal body;
One bolt, the one of which end is threaded with the other end of nut;
One hammer body, it is arranged on the bolt, and can slide along the axial direction of bolt.
When adopting the described provision for disengagement dismounting of present technique scheme spring catch; Need earlier the gripper section of pin removal body to be knocked in the centre bore of spring catch; Fasten spring catch end face until gripper, then plug put in the pin removal body near blind-hole bottom, and with nut screwing clamping on the thread segment of pin removal body; Subsequently bolt is installed in the other end of nut; Again hammer body is arranged on the bolt, makes the end face of hammer body then, so that the end of gripper applies an active force for the bottom surface of blind hole along the axial direction hammering nut of bolt; Simultaneously the bottom surface of blind hole gives reaction force of end of gripper, this reaction force and then make the terminal convexity of gripper that spring catch is released from blind hole.
Preferably, in above-mentioned blind hole spring catch provision for disengagement, the other end of the bolt backstop nut that also has been threaded.
Preferably, in above-mentioned blind hole spring catch provision for disengagement, have the pin-and-hole offered along its radial direction on the pin removal body, pin-and-hole is located at the place ahead of nut one end end face.This pin-and-hole be set be for nut screwing clamping on the pin removal body.
The provision for disengagement of the described blind hole spring catch of the utility model can be dismantled the spring catch on the shaft coupling easily; And significantly reduced and dismantled the consuming time of spring catch; The average consuming time of a spring catch of dismounting was reduced to 5 minutes from originally 30 minutes; Thereby significantly reduced the downtime of unit fault, and alleviated maintainer's labour intensity.
