[Solution] The tool sleeve used in the machining equipment includes a tool sleeve body, a tool locking device, and a positioning block. The tool sleeve body has a fitting hole into which a cone-shaped handle of the tool handle is inserted. The tool locking device is for providing radial force to the cone-shaped handle inserted into the fitting hole.

Description

Technical Field

[0001] The present invention relates to a storage configuration of a tool handle used in a composite processing device, and particularly to an injection mold for manufacturing a tool sleeve for a processing device and a tool sleeve body of the tool sleeve.

Background Art

[0002] A known tool handle (also called a tool bar) used in a processing device serves as a bridge between the spindle and the tool in a machine tool. In a processing process controlled by a computer, for example, in order to smoothly realize machining operations such as drilling, milling, facing, and turning, the tool fixedly connected to the tool handle also varies accordingly. Commonly seen tools include, for example, a milling cutter, a reamer, a boring bar, a dish hole tool, and a turning tool. In order to meet the needs of composite machining, a tool magazine and a tool changing mechanism may be arranged in the processing device. The tool magazine provides a plurality of tool sleeves for attaching and inserting a plurality of tool handles. Different tools are fixedly connected to each tool handle. The tool changing mechanism is separately installed in the tool magazine to enhance the working efficiency and is used for quickly exchanging the tool handle (together with the tool) of the spindle in the machine tool.

[0003] To ensure precision in machining, a tool alignment point (also called the workpiece origin) must be selected before machining to prepare for the next step of tool alignment. The tool alignment process involves ensuring that the tool point and the tool position point correspond to each other. This aims to determine the absolute coordinate value of the tool alignment point in the tool machine's coordinate system and measure the tool position deviation of the tool. The tool alignment point refers to the starting point from which the tool moves relative to the workpiece when a digitally controlled machine tool is machining the workpiece. This point may be set on the workpiece, a jig, or the machine tool itself. The tool alignment point refers to the point used to position the tool; for example, with a cutting tool, the tool position point is the tip of the tool. As can be seen from the above, in automated machining processes, the tool position point is extremely important, and different tool position points are set for different tools depending on the machining process. Furthermore, in order to ensure that the tool can be accurately retrieved by the tool changing mechanism by maintaining the tool position point of each tool in the tool magazine at a predetermined position, conventional designs achieve the objective of stabilizing the tool position point by manufacturing the tool sleeve body, which constitutes the tool sleeve, in various shapes, and then inserting the tool handle that fixes and connects different tools into it to obtain positioning. However, this design inevitably increases the cost of manufacturing the tool sleeve body, and in particular, when manufacturing the tool sleeve body by injection molding, it is not possible to manufacture multiple types of tool sleeve bodies without a large number of dedicated molds, thus increasing costs. [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] In view of this, the present invention aims to provide a tool sleeve for processing equipment and an injection molding die for a tool sleeve body for manufacturing the tool sleeve. Furthermore, the tool sleeve can stably house a tool handle and prevent the tool handle from rotating improperly. The injection molding die can produce tool sleeve bodies of multiple model numbers, and the positioning configurations provided in tool sleeve bodies of different model numbers can be positioned in different orientations. [Means for solving the problem]

[0005] To achieve the above objective, the tool sleeve provided by the present invention includes a tool sleeve body, a tool locking device, and a positioning block. The tool sleeve body has a fitting hole and defines a virtual axis passing through the center of the fitting hole into which the cone-shaped handle of the tool handle is inserted. The tool locking device is for providing radial force to the cone-shaped handle inserted into the fitting hole. The positioning block is connected to the tool sleeve body so as to be fixed and has a positioning portion that is exposed so as to protrude into the fitting hole. As a result, when the cone-shaped handle of the tool handle is inserted into the fitting hole, the positioning portion of the positioning block is fitted into the positioning groove of the tool handle, and the tool handle is unable to rotate relative to the tool sleeve body about the axis.

[0006] The injection molding die provided by the present invention can manufacture a tool sleeve body having a partition and a fitting hole inside. The partition has a mounting hole, and the mounting hole communicates with the fitting hole and the outside of the tool sleeve body. The injection molding die includes a molding die, a first slider and a second slider, of which the molding die includes a first half die and a second half die, each half die including a mold dividing surface and an inner surface formed recessed from the mold dividing surface, and when the mold dividing surface of the first half die and the mold dividing surface of the second half die are joined, the inner surface of the first half die and the inner surface of the second half die together constitute a hollow chamber. The first slider and the second slider can move between an inserted position and an uninserted position relative to the molding die from both sides of the molding die along a virtual baseline. The first slider has a first end face and a split column that protrudes from the first end face and is deflected away from the baseline, and the second slider has a conical column with a second end face. When the first half and the second half are aligned and the first slider and the second slider are in the insertion position, the split column and the conical column are located in the hollow chamber, leaving a gap between the first end face and the second end face. The split column is for forming the mounting hole in the tool sleeve body, the conical column is for forming the fitting hole in the tool sleeve body, and the gap between the first end face and the second end face is for forming the partition in the tool sleeve body. [Effects of the Invention]

[0007] Therefore, by adjusting the first slider and the second slider located in the uninserted position, the injection molding die can rotate around the baseline between multiple fixed points, thereby producing tool sleeve bodies of multiple model numbers, and the positioning configurations provided on tool sleeve bodies of different model numbers will be positioned in different orientations. This significantly reduces the cost of using multiple molds. [Brief explanation of the drawing]

[0009] The tool sleeve provided by the present invention, depending on the tool position point of different tools, can not only provide an effect of improving the positioning of the stored tool handle, but the tool sleeve body, which is one of its components, further has a positioning configuration by processing an injection molding die, and the positioning configuration can prevent the rotation of the tool handle by installing a positioning block, and by ensuring that the position point of the tool fixedly connected to the tool handle is held at the set position, the tool exchange mechanism can be taken out and used according to the next machining process.

[0010] Hereinafter, a preferred embodiment of a tool sleeve capable of achieving the above objectives according to the present invention will be described. As shown in Figure 1, the tool sleeve 100 according to a preferred embodiment of the present invention is applied to a tool handle 200 used to house a multi-tasking machine. The tool handle 200 has a cone-shaped handle 201, the cone-shaped handle 201 has an end face 201a and an outer surface 201b, the tool handle 200 has a shaft hole 202 formed recessed from the end face 201a, a recessed annular groove 203 is provided in the wall of the shaft hole 202, and a positioning groove 204 is provided at the connection portion between the end face 201a and the outer surface 201b.

[0011] Referring to FIG. 2, the tool sleeve 100 includes a tool sleeve body 10, a positioning block 20, and a tool locking device 30. Referring again to FIGS. 3 to 5, the tool sleeve body 10 is an injection-molded hollow mold product, having a partition 12 inside, and forming a fitting hole 14 on one side of the partition 12. The partition 12 has an axial hole 12a and a radial hole 12b. One end of the axial hole 12a communicates with the fitting hole 14, and the other end communicates with the outside of the tool sleeve body 10. One end of the radial hole 12b communicates with the axial hole 12a, and the other end communicates with the outside of the tool sleeve body 10. The partition 12 has a mounting hole 12c and four through holes 12d. The mounting hole 12c and the plurality of through holes 12d are installed in a form parallel to the axial hole 12a. One end of the mounting hole 12c communicates with the fitting hole 14, and the other end communicates with the outside of the tool sleeve body 10. In addition, the tool sleeve body 10 further forms a stop surface 16 at the connection part between the hole wall of the mounting hole 12c and the hole wall of the fitting hole 14. A virtual axis L passing through the centers of the fitting hole 14 and the axial hole 12a is defined, and the tool handle 200 inserts the tapered handle 201 into the fitting hole 14 along the axis L.

[0012] In this embodiment, the positioning block 20 is formed of medium carbon steel and has a long strip shape. The positioning block 20 is inserted into the mounting hole 12c in the tool sleeve body 10. The mounting hole 12c has the above-described positioning configuration. As shown in FIGS. 3 and 4, one end of the positioning block 20 abuts against the stop surface 16, and a part of it is exposed so as to protrude into the fitting hole 14. Here, the protruding exposed part is defined as a positioning portion 22.

[0013] The tool locking device 30 provides radial force to the cone-shaped handle 201 inserted into the fitting hole 14 in the tool sleeve body 10, ensuring that the tool handle 200 is stably housed in the tool sleeve 100. As shown in Figures 2, 6, and 7, the tool locking device 30 includes an axial pipe 31, a plurality of balls 32, an unlocking part 33, a spring 34, a screw 35, a gasket 36, a retaining piece 37, and a plurality of bolts 38. Of these, the axial pipe 31 is located in the fitting hole 14 and has a plurality of lateral opening holes 31a in its tubular body, and an enclosure 31b is formed in the inner wall of the tubular pipe so as to protrude toward the center. The plurality of balls 32 are each located in the lateral opening holes 31a. The unlocking part 33 drills through the axial pipe 31 and is capable of reciprocating along the axis L. The unlock portion 33 has a conical push-up portion 33a at one end, which maintains contact with the plurality of balls 32. The spring 34 is covered by the unlock portion 33, and one end of the spring contacts the enclosure 31b. The screw 35 passes through the gasket 36 and is locked into the screw hole 33b in the unlock portion 33. Thus, the unlock portion 33, the screw 35, and the gasket 36 are considered to be an integrated unit, and the other end of the spring 34 contacts the gasket 36. The blocking piece 37 has a plurality of through holes 37a, and the plurality of bolts 38 are locked into the corresponding screw holes (not shown) in the shaft piping 31 when they pass through the through holes 37a located in the blocking piece 37 and the through holes 12d located in the partition 12 in the tool sleeve body 10.

[0014] When the plurality of bolts 38 are tightened, the shaft pipe 31 and the blocking piece 37 firmly sandwich both sides of the partition 12 respectively, and the blocking piece 37 abuts against the other end of the positioning block 20, ensuring that the positioning block 20 is stably inserted into the mounting hole 12c. An elastic force of the spring 34 applies a pushing force to the unlocking portion 33, and the pushing-up portion 33a pushes the plurality of balls 32 outward. When the conical handle 201 of the tool handle 200 is inserted into the fitting hole 14, due to the pushing force of the spring 34, indirectly, a part of the plurality of balls 32 enters and abuts against the annular groove 203, ensuring that the tool handle 200 does not easily disengage from the tool sleeve 100, and the force exerted by the ball 32 on the annular groove 203 is the radial force defined in the present invention. On the other hand, when trying to take out the tool handle 200, while inserting an auxiliary tool into the radial hole 12b in the tool sleeve body 10 and pushing the screw 35 upward with the auxiliary tool, the unlocking portion 33 moves and compresses the spring 34 by pushing, and the plurality of balls 32 leave the annular groove 203, thereby achieving the purpose of unlocking.

[0015] As described above, when the conical handle 201 of the tool handle 200 is inserted into the fitting hole 14, the positioning portion 22 of the positioning block 20 also simultaneously fits into the positioning groove 204 (see FIG. 7) of the conical handle 201, making the tool handle 200 unable to rotate relative to the tool sleeve body 10 around the axis L. Based on the above, after fixing and connecting a tool to the tool handle 200 and specifying the tool position point of the tool, the tool exchange mechanism can take out the accurate tool handle 200 according to the processing process for the next processing operation.

[0016] Referring again to Figures 1, 8, and 9, the tool handle 200 according to this embodiment has a conical handle 201 that is a polygonal cone, and its outer surface 201b is a non-circular circumferential surface formed by connecting three arcuate surfaces, and the conical handle 201 has an outward projection 201c at the connection point of adjacent arcuate surfaces. The fitting hole 14 according to this embodiment, together with the conical handle 201, becomes a non-circular hole, and has three inward projections 14a formed on its wall, and recesses 14b formed between adjacent inward projections 14a. When the conical handle 201 of the tool handle 200 is inserted into the fitting hole 14, each inward projection 14a in the fitting hole 14 contacts the corresponding arcuate surface of the conical handle 201 to form a contact point T, thereby stably supporting the tool handle 200. Each outward projection 201c of the conical handle 201 is located in the corresponding recess 14b. As can be seen from Figure 8, there is a gap between the outward projection 201c and the recess 14b. This gap allows dust and debris adhering to the tool handle 200 to be discharged. As shown in Figure 9, the positioning groove 204 is located on the arcuate surface and the positioning block 20 is located on the inward projection 14a. It should be noted that the conical handle of the tool handle may be a cone, and the fitting hole may be a conical hole.

[0017] The above describes the configuration of a tool sleeve according to a preferred embodiment of the present invention. Below, an injection molding die for manufacturing a tool sleeve body having a positioning configuration (i.e., the mounting hole) according to the present invention will be described. The injection molding die can be configured so that the positioning configuration manufactured by processing is located at different positions by adjusting the position of some of its components. In other words, by adjusting the position of some of the components in the injection molding die, based on the setting that the orientation of the tip and end of the tool sleeve body is fixed, the positioning configuration of the manufactured tool sleeve body will be located at different parts within the fitting hole. More details are as follows.

[0018] Referring to Figures 10 and 11, the injection molding die 300 according to this embodiment includes a molding die 310, a first slider 320, and a second slider 330. Of these, the molding die 310 is composed of a first half-mold 311 and a second half-mold 312 that face each other and can be closed or opened. Referring to Figure 12, the first half-mold 311 has a mold dividing surface 311a and an inner surface 311b formed recessed from the mold dividing surface 311a, and the second half-mold 312 has a mold dividing surface 312a and an inner surface 312b formed recessed from the mold dividing surface 312a. When the mold dividing surface 311a of the first half-mold 311 and the mold dividing surface 312a of the second half-mold 312 are joined, the inner surface 311b of the first half-mold 311 and the inner surface 312b of the second half-mold 312 together constitute a hollow chamber S. The molding die 310 has a first opening 301 and a second opening 302 on both sides, the first opening 301 and the second opening 302 are in communication with the hollow chamber S, and a virtual baseline L1 is defined passing through the first opening 301, the hollow chamber S and the second opening 302.

[0019] The first slider 320 and the second slider 330 are located separately on both sides of the molding die 310 and together on the virtual baseline L1. When controlled, the first slider 320 and the second slider 330 are not only able to move back and forth along the baseline L1 relative to the molding die 310, but are also adjusted to be rotatable about the baseline L1. The first slider 320 has a first end face 321 and a split column 322 protruding from the first end face 321, and the split column 322 is located on one side deflected from the baseline L1. The second slider 330 has a conical column 331, which has an outer surface 332 and a second end face 333, the outer surface 332 being a non-circular circumferential surface, and a central column 334 and a plurality of extension columns 335 protruding from the second end face 333.

[0020] As shown in Figure 10, when the first half mold 311 and the second half mold 312 are aligned, the first slider 320 and the second slider 330 located on both sides of the molding main mold 310 are defined to be in the uninserted position P1. As shown in Figures 13 and 14, when controlled, the first slider 320 and the second slider 330 extend along the baseline L1, respectively, through the first opening 301 and the second opening 302 into the hollow chamber S, and are defined to be in the insertion position P2 when in this state. At the same time, the split column 322 of the first slider 320 and the conical column 331 of the second slider 330 are located in the hollow chamber S, and a gap distance W is left between the first end face 321 and the second end face 333.

[0021] The injection molding die 300 is connected to an injection molding machine (not shown) in the state shown in Figures 13 and 14. The injection molding machine pours molten plastic into the injection molding die 300 from the injection molding port 303, filling the hollow chamber S. When the plastic is cooled and the mold is fixed, the first slider 320 and the second slider 330 are controlled to retract to the uninserted position P1 along the baseline L1. At this time, the plastic that is filled between the outer surface of each slider 320 (330) and the inner surface 311b (312b) of each half-mold forms a cylindrical shape in the tool sleeve body 10 when cooled and the mold is set. The plastic that is filled between the first end face 321 and the second end face 333 forms a partition 12 in the tool sleeve body 10, and the thickness of the partition 12 corresponds to the interval distance W. Furthermore, the space separated by the split column 322 in the first slider 320 forms the mounting hole 12c in the tool sleeve body 10, as well as the stop surface 16 in the hole wall of the fitting hole 14. The space separated by the central column 334 in the second slider 330 forms the axial hole 12a in the tool sleeve body 10, the space separated by its extension column 335 forms the multiple through holes 12d in the tool sleeve body 10, and the space separated by its conical column 331 forms the fitting hole 14 in the tool sleeve body 10. The molded product removed by opening the first half mold 311 and the second half mold 312 becomes the tool sleeve body 10.

[0022] As can be seen by referring to Figure 9 in conjunction with the above, in this embodiment, when the virtual vertical line L2 passes through its tip 10a and end 10b, the mounting hole 12c and the positioning block 20 of the tool sleeve body 10 will be located on the left side. Furthermore, as described above, the injection molding die according to the present invention can achieve the effect of having the mounting hole located in a different orientation inside the fitting hole by adjusting the position of some parts. As shown in Figure 15, based on the fact that the direction in which the first half mold 311 and the second half mold 312 are aligned remains unchanged, the first slider 320 and the second slider 330 located at the uninserted position P1 are adjusted, that is, the first slider 320 and the second slider 330 are rotated by 90 degrees around the baseline L1, and then the injection and manufacturing process is carried out in the same manner as above, so that the mounting hole 12c of the acquired tool sleeve body 10A is located upward as shown in Figure 16. Similarly, if the first slider 320 and the second slider 330 are adjusted to rotate 90 degrees, the mounting hole 12c of the acquired tool sleeve body 10B will be located on the right side as shown in Figure 17. Furthermore, if the first slider 320 and the second slider 330 are adjusted to rotate 90 degrees again, the mounting hole 12c of the acquired tool sleeve body 10C will be located downwards as shown in Figure 18.

[0023] As can be seen from the above description, the first slider and the second slider in the injection molding die according to the present invention are controlled to rotate between multiple fixed points, and the positioning configuration within the fitting hole (i.e., the mounting hole) in the tool sleeve body produced and manufactured at different fixed point positions is located in different orientations, as shown in Figures 9, 16 to 18. The tool handle for fixing and connecting different tools is selected by inserting the appropriate tool sleeve body into the appropriate location, and the tool position point of the tool on each tool handle can be effectively maintained at the set position. Furthermore, in the present invention, multiple types of tool sleeve bodies can be produced using only a single mold, significantly reducing the cost of using multiple molds.

[0024] The fixed point positions mentioned above rotate 90 degrees relative to each other, but the angle of rotation may be pre-set according to actual needs. Furthermore, the rotation of the second slider does not necessarily have to be synchronized with that of the first slider; the first slider may be rotated while the second slider is not rotated.

[0025] The above description represents only preferred implementable embodiments of the present invention, and any equivalent substitutions made by applying the claims together with the specification of the present invention should be included within the scope of the claims of the present invention.
