Spindle structure

The present invention is related to a spindle structure, which is disposed on each tool main body, and particularly the first connector group of the main shaft structure is disposed between the first rod group and the second rod group. That is, the first connector group is connected to the first rod group and the second rod group, and the first connector group, the first rod group or the second rod group can be disabled when one of them fails The other of the phase sets is disengaged from each other to replace the faulty part, and the present invention is convenient.

As we have previously known, the spindle structure used in the machine tool is used, such as Taiwan Patent Application No.: 090222335, patent name: parallel shrapnel mechanism for the spindle loose broach. The patent structure is: a spindle loose broach The parallel type shrapnel mechanism comprises a spindle body 5, a spindle 6 inserted into the spindle body 5, a spring mechanism 7, and a knife device 8; the spindle body 5 has an axial receiving a hole 51 for arranging the mandrel 6 , wherein the main shaft body 5 further has a first accommodating groove 52 which is axially and radially expanded with respect to the accommodating hole 51 , and a first accommodating groove 52 a second receiving groove 53 is disposed on the front side of the groove 52. The mandrel 6 has a spindle body 60, and a resisting member disposed at the end of the spindle body 60, and a radial insertion of the first and second receiving portions. a latch 62 between the slots 52, 53 and passing through the spindle body 60, and a knife ring 63 disposed on the latch 62; the spring mechanism 7 has a first tandem spring set 71, and a second string The array of elastic pieces 72, the first series of elastic pieces 71 are fitted on the spindle body 60, and are accommodated The first receiving groove 52, which is the front end surface abuts on a bottom wall 521 of the first receiving groove 52, abuts the other end surface of the heart On the shaft body 60, the second array of elastic pieces 72 is also disposed on the spindle body 60, and is received in the second receiving groove 53, and an end surface thereof abuts against the second receiving groove. On one of the groove walls 531, the other end face abuts against the resisting member, and the knife-making device 8 has a cutter cylinder 81 for pushing the displacement of the cutter ring 63, and the cutter cylinder 81 is used as the cutter cylinder 81. When the cutter ring 63 and the latch 62 are driven to press the spindle body 60, the spindle body 60 can be relatively displaced, and the first and second tandem spring assemblies 71 and 72 are pressed to compress the two. The elastic tension is formed for the purpose of reversely shifting the spindle body 60 to the initial position for the purpose of the reverse broach.

However, the missing structure of this conventional spindle structure is:

The pin 62 is disposed between the first accommodating groove 52 and the second accommodating groove 53 and passes through the mandrel body 60 and the mandrel 6 to receive the mandrel 6 in the accommodating hole. In the 51, the knife device 8 has a knife cylinder 81 for pushing the displacement of the knife ring 63, and a knife set on the last side and locked by a nut 54 on the spindle 5. The top block 82, that is, the spindle body 5, the spindle 6 and the tooling device 8 are in an integrally assembled state, and when the spindle structure performs a knife-cut state, if the spindle body 5 or the spindle 6 or the cutter When the device 8 fails, the spindle structure is completely faulty and a single part cannot be replaced.

In view of the above-mentioned lack of the conventional spindle structure, the inventors have been engaged in the manufacturing, production, and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the spindle structure.

The spindle body, the mandrel and the cutter The system is in an integrated state. When the spindle structure performs the tooling state, if the spindle body or the spindle or the tooling device fails, the spindle structure is completely faulty, and the single component cannot be replaced. The first connector set of the spindle structure of the invention is disposed on the first tie rod set and the first Between the two tie rod groups, that is, the first connector group is connected to the first tie rod group and the second rod group, the first connector group, the first rod group or the second rod group, one of the In the event of a failure, the other of the groups can be disengaged from each other to replace the defective part, and the present invention is convenient.

A spindle structure comprising: a body; a rotating shaft is pivotally disposed in the body; a first connecting member is sleeved in the rotating shaft, the first connecting member comprises a first connecting member, a plurality of first pressing members and a plurality of first screws The first connecting member is provided with a first joint portion, a second joint portion, and a plurality of first threaded portions; the first pressure member is received at the first screw portion, and the first pressure member is at one end a first threaded portion is disposed; the first threaded member is locked at the first screwing portion; a first rod group is sleeved in the rotating shaft, and the first rod group is coupled to the first rod portion a first set of tie rods includes a first pull rod, a spring member, a pressing member and an adjusting member; the first pull rod is provided with a third joint at one end to be sleeved with the first joint portion The third joint portion is externally threaded, and the third joint portion is screwed by the first screw portion and pressed by the first screw member; a second tie rod set is sleeved on In the rotating shaft, the second rod group is assembled with the first connecting member group, and the second rod group is provided with a second rod.

The first connector set is disposed on the first pull rod set And the first connecting rod set is connected between the first connecting rod set and the second pulling rod set, the first connecting piece set, the first pulling rod set and the second pulling rod set, one of the first connecting rod sets If a fault occurs, the other one of the groups can be disconnected, and the faulty part can be replaced with convenience. Generally, the most common damage is the second pull rod, and the second pull rod can be directly removed from the first connecting member, so that the first connecting member group, the first connecting rod group and the The second pull rod set is removed from the rotating shaft, which makes it easier to replace the second pull rod. The first rod is displaced, and the spring member is compressed by the pressing member to compress the first connecting member group and the second rod group By being displaced by the first connecting member, the user can remove the tool from the rotating shaft and the first pull rod. When the third joint portion is engaged with the first joint portion of the first joint member, the third joint portion is received by the first pressure receiving member at the first screw portion. The threaded portion of the screw is pressed against the pressing force of the first screwing member, so that the third joint portion is more difficult to be disengaged from the first joint portion.
