Description

A TOOL MAGAZINE DEVICE

The present invention relates to an automatic tool changer. And more particularly to a cutter holder device applied to different tool shank structures.

Conventionally, a tool shank used in a machine equipped with an automatic tool changer is roughly divided into two structures according to different machining demands. One of them is the tool shank 1 shown in Fig. 1 (a), which is applied to heavy-duty cutting with a relatively slow rotational speed, and in order to prevent the tool shank 1 from revolving during machining, And two position fixing bars on the main shaft of the machine are inserted into the respective coupling grooves 1a so that the heavy cutting process can be smoothly performed. The other is a tool shank 2 shown in Fig. 1 (b). Since the engaging groove is not designed on the outer circumferential surface thereof, the weight of the tool shank main body is balanced and applied to high speed turning.

Conventional automatic tool changers must simultaneously have tool shanks having different structures in order to smoothly receive and clamp the different types of tool shanks. For example, in the case of the cutter holder of the tool shank 1 shown in Fig. 1 (a), a position fixing member is provided on the inner edge of the cutter holder and inserted into one coupling groove 1a of the tool shank 1. [ The purpose is to fix the position of the tool shank 1 and smoothly take out the next cutter. Conversely, it is not necessary to provide a position fixing member on the inner edge of the cutter holder of the tool shank 2 shown in Fig. 1 (b). As can be seen from the above, the cutter holders each have specificity and are incompatible with each other. If there is an error in arrangement of the cutter holder and the tool shank, the tool shank can not be stably clamped, There is a concern that it may lead to the departure of Shank.

In view of this, the object of the present invention is to provide a cutter holder device which is applied for clamping and using a tool shank having an engaging groove or no engaging groove.

In order to achieve the above object, the present invention provides a cutter holder device comprising a base and at least one cutter holder, the cutter holder being coupled to the base in a detachable manner, Wherein the two clamping arms are spaced apart from each other such that an opening is formed to allow the tool shank to enter and exit the cutter holder and the two clamping arms Wherein the tool shank is used to clamp the tool shank and the cutter holder has a contact surface between the two clamping arms, the contact surface and the tool shank being in contact with each other. Wherein the cutter holder device further comprises a pressing member, wherein the pressing member has a protruding end located between the two clamping arms and located in front of the contact surface, the protruding end being in contact with the contact surface Retract to the retracted position.

The effect of the present invention is that when the cutter holder clamps the tool shank having the engaging groove, the protruding end of the pressing member is inserted into the engaging groove, and when the cutter holder clamps the tool shank having no engaging groove, The protruding end of the protruding portion is pressed and retracted. This makes it possible to solve the problem that the clamping is unstable due to an error in the arrangement of the cutter holder and the tool shank, and the tool shank deviates.

As shown in Fig. The base 10 includes a ring frame 12 and a binding sheet 14 stretched from both sides of the ring frame 12, respectively. The ring frame 12 is mounted on a rotatable shaft (not shown), and the two engagement sheets 14 are symmetrical and each one cutter holder 20 is coupled in a detachable manner. Hereinafter, the mounting of one cutter holder 20, one first bolt 30, one second bolt 40 and one pressing member 50 will be described as an example.

The base 10 has an upper surface 10a and a lower surface 10b which are opposite to each other. Each of the engagement sheets 14 has a recessed portion (recessed portion) from the upper surface 10a and a bottom portion of the recessed portion is a support surface 14a. On both sides of the support surface 14a, Are blocking walls 14b. The bottom surface 10b of the base 10 is recessed to form an engaging groove 10c and one end of the engaging groove 10c is communicated with the side surface of the engaging sheet 14. [ The base 10 further includes a first screw hole 10d, a second screw hole 10e and two position fixing holes 10f, and the first screw hole 10d, And the two positioning holes 10f penetrate through the support surface 14a and the bottom surface 10b of the engaging groove 10c, and the two position fixing holes 10f penetrate the support surface 14a and the bottom surface 10b .

5, the cutter holder 20 of this embodiment is injection molded of a composite material comprising plastic, and the cutter holder includes a main body 22 and two clamping arms 24 . The body 22 has a through hole 22a, and two position fixing bars 22b protrude and extend from the bottom face. When the cutter holder 20 is disposed on the support surface 14a through the main body 22, the two position fixing bars 22b are fixed to the two position fixing holes 10f of the base 10 Is correctly inserted. The cutter holder 20 can be fixedly coupled to the base 10 by passing the second bolt 40 through the through hole 22a and fastening the second bolt 40 to the second screw hole 10e . The cutter holder 20 is regulated by the two blocking walls 14b and the position fixing bar 22b is engaged with the position fixing hole 10f so that the cutter holder 20 can freely move left and right none. One end of the second bolt 40 is exposed to the outside through the second screw hole 10e.

One end of the two clamping arms 24 of the cutter holder 20 is connected to the main body 22 and the other end is not surrounded by the peripheral edge of the base 10. [ The two clamping arms 24 have a slight elasticity and an opening is formed between the front ends so as to allow the tool shank to enter and exit the cutter holder 20. The cutter holder 20 has a contact surface 20a between the main body 22 and the two clamping arms 24 and a protruding rib 20b is protruded from the contact surface 20a. The cutter holder 20 is provided with a slot 20c formed to be recessed from the contact surface 20a and the slot 20c is positioned in the direction in which the tool shank enters and exits the cutter holder 20 do. Specifically, the slot 20c is located in the main body 22 and below the protruding rib 20b.

6A and 6B, the pressing member 50 is a rectangular elastic sheet including the first sheet body 52 and the second sheet body 54 in the present embodiment, In an application example, the elastic sheet is made of a spring steel plate. The thickness of the elastic sheet is preferably 0.3 to 0.7 mm, and more preferably 0.5 mm. The first sheet body 52 and the second sheet body 54 of the elastic sheet are connected in an L-shape, and a narrow angle between the first sheet body 52 and the second sheet body 54 is an obtuse angle of 95 ° to 120 °. The first sheet body 52 has a first hole 52a and a second hole 52b and one end of the second sheet body 54 forms a protruding end 54a.

The first sheet body 52 of the elastic sheet is inserted into the engaging groove 10c of the base 10 and one end exposed to the outside of the second bolt 40 is inserted into the second hole 52b. The first bolt 30 passes through the first hole 52a from the bottom to the bottom and is fastened to the first screw hole 10d of the base 10, The elastic sheet is fixed to the base 10 when the first sheet body 52 is pressed in the first sheet body 30a. The elastic sheet after the assembly is arranged such that the protruding end 54a at one end of the second sheet body 54 is located in a space surrounded by the main body 22 and the two clamping arms 24, Located. It should be noted that the elastic sheet is limited by the engagement groove 10c and the first bolt 30 and the second bolt 40 provide a fixing effect at two points, 10).

Hereinafter, the cutter holder device 100 of the present embodiment is applied to the tool shank 1 having the engaging groove 1a as shown in Fig. 1 (a), or to the tool shank 1 having the engaging groove as shown in Fig. 1 (b) It is again explained that the tool shank 2 is applied and clamped and used. First, when the tool shank 1 and the tool shank 2 are clamped, the contact surface 20a of the cutter holder 20 of this embodiment is in contact with the outer peripheral surface of the tool shank, and the protruding rib 20b And inserted into the annular groove 1b or 2a on the outer peripheral surface of the tool shank to prevent the tool shank from descending. Of course, the outer circumferential surface of the tool shank does not necessarily have to be in contact with the contact surface 20a, and a fine gap should be maintained if necessary.

2 to 4, in the process of mounting the tool shank 1 to the cutter holder 20, the engaging hole 1a on the circumferential surface of the tool shank 1 is engaged with the engaging hole 1a, When the tool shank 1 is clamped and fixed to the clamping arm 24, the projecting end 54a of the second sheet body 54 is not pressed Or the pressing force is small so that the inserted state is maintained in the engaging groove 1a. This situation is advantageous in that the tool shank 1 is fixed in position, and it is possible to smoothly take out the next cutter. The protruding end 54a of the second sheet body 54 is positioned at the position where the tool shank 2 does not have the engaging groove when the other tool shank 2 is mounted on the cutter holder 20. Therefore, And is deformed by the pressing action from the shank 2 to retreat to the slot 20c and substantially coincide with the contact surface 20a. Therefore, the arrangement of the cutter holder 20 and the pressing member 50 of the present embodiment can reliably prevent the problem that the clamping is unstable due to an error in arrangement of the cutter holder 20 and the tool shank, thereby causing the tool shank to deviate. Further, since the tool shank is provided with a coupling groove or is not provided with a coupling groove and is used by being clamped, it is possible to reduce the cost expenditure.

In the above description, the base 10 is for mounting only two cutter holders 20, but in practice, it is possible to correspond to different machines, and the base may be constituted of a circular plate type structure, A plurality of cutter holders 20 can be arranged and mounted.
