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 spindle structure is disposed between the first pull rod group and the second pull 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 creation can be 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 conventional spindle structure is missing in that the pin 62 is radially inserted between the first accommodating groove 52 and the second accommodating groove 53 and passes through the spindle body 60 and the spindle 6 so that the pin The spindle 6 is received in the receiving hole 51. The cutter device 8 has a cutter cylinder 81 for pushing the shifting of the cutter ring 63, and a set is disposed on the last side and is supported by the spindle 5. a nut 54 is locked and positioned to the top block 82, that is, the spindle body 5, the spindle 6 and the cutter device 8 are integrally assembled. When the spindle structure performs a knife state, if the spindle body 5 or the mandrel 6 or the knife device 8 fails, the spindle structure is completely faulty, and a single part cannot be replaced.

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

A new type of problem to be solved: the spindle body, the mandrel and the tooling device are in an integrated state, and when the spindle structure performs a knife state, if the spindle body or the spindle or the knife device When the fault occurs, the spindle structure is completely faulty, and the single component cannot be replaced. The first connector group of the spindle structure of the present invention is set in the first tie rod group 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 creation can be convenient.

The technical means for solving the problem: a spindle structure, comprising: a body; a rotating shaft system is pivoted in the body; a first connecting member set is sleeved in the rotating shaft, the first connecting member set The first connecting member, the plurality of first pressing members and the plurality of first screwing members; the first connecting member is provided with a first joint portion, a second joint portion, and a plurality of first screwing portions; the first pressure member The first screwing portion is disposed at one end of the first screwing portion; the first screwing member is locked at the first screwing portion; a first pull rod group is Nested in the rotating shaft, the first rod group is assembled with the first connecting rod set, the first rod group includes a first rod, a spring member, a pressing member and an adjusting member; the first rod a third joint portion is disposed 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 threaded portion and the first joint portion a pressing force of a screwing member; a second rod group is sleeved in the rotating shaft, and the second rod group is combined with the first connecting member group , The second rod has a second rod set of lines.

According to the prior art, the first connector group is disposed between the first rod group and the second rod group, and the first connector group is connected to the first rod group and the second rod group, the first A connector set, the first pull rod set and the second pull rod set can be disengaged from the other one of the groups when one of them fails, so that 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.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to impose any form of restriction on this creation. Any modification made in the spirit of this creation should still fall within the scope of this creation.
