Abstract

To provide a tool sleeve for storing a processing tool, which can extend the service life of a spring by reducing the load when an acting force is generated when the spiral winding of the spring is pressed in a tool lock configuration. [Solution] The tool sleeve body (10) has a mounting surface on its outer periphery and a plurality of radial holes (16) drilled downward from the mounting surface. The tool locking means includes a spring and a steel ball (22) placed in each radial hole. The pressing part is a steel strip that is installed along the mounting surface and covers the plurality of radial holes. The fixing means connects the steel strip to the tool sleeve body so that the steel strip is fixed and surrounds the tool sleeve body.

Description

[Technical Field]

[0001] The present invention relates to an automatic tool changer for a tool machine, and more particularly to a tool sleeve that is attached to a tool magazine and that stores machining tools. [Background technology]

[0002] In an automatic tool changer for a tool machine, a tool magazine provides the tool storage and tool change needs required for automated machining. The tool magazine has multiple tool sleeves for mounting and inserting tool rods with various tool specifications. To prevent the tool rod from accidentally falling out of the tool sleeve, which could result in damage to the tool rod or tool and unnecessary safety issues during operation, known tool sleeves have a tool locking mechanism. Examples of such patented utility models include Taiwan Patent No. M563937 ("Tool Sleeve Structure with Safety Engagement Device"), Taiwan Patent No. M439538 ("Improvement to Tool Sleeve Structure in Tool Magazine for Tool Machine"), and Taiwan Patent No. M477934 ("Tool Sleeve Device"). The tool locking mechanism in these patented technologies includes multiple radial holes located at the rear of the tool sleeve. Steel balls and springs are placed in each radial hole, and multiple screws are then locked into the radial holes to prevent the steel balls and springs from falling out. The spring uses its elastic force to push up the steel ball and press it so that the steel ball is inserted into one end of the tool sleeve while firmly abutting against the tool rod, thereby performing an engagement function and achieving the purpose of preventing the tool rod from accidentally falling out.

[0003] While the tool locking structure of the above-mentioned patent can prevent the tool bar from accidentally falling out, the depth of each radial hole in the tool sleeve and the fact that the screw and steel ball occupy part of the space in the radial hole mean that only springs with a relatively short length can be used. Furthermore, the spring length refers to the distance between both ends of the spring before deformation. Therefore, a relatively short spring also has a smaller number of turns of the helical winding. When the tool bar advances through the tool sleeve and pushes the steel ball, the steel ball pushes against the spring, causing compression and deformation. The compression and deformation of the spring are achieved by torsion of the helical winding. Therefore, when a relatively short spring is repeatedly subjected to a force due to being pushed, the load applied to the helical winding is likely to increase, especially as the helical winding approaches the steel ball. Over a long period of time, the helical winding will fatigue, causing cracks and even breakage. Furthermore, the operation of locking the screws into each radial hole is not only time-consuming, but also causes uneven pressure on the steel balls from the springs if the depths of the screws locked into the radial holes do not match. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of this, an object of the present invention is to provide a tool sleeve for storing a machining tool, which can extend the service life of the spring by reducing the load when an acting force is generated when the spiral winding of the spring is pressed in a tool locking configuration. [Means for solving the problem]

[0005] To achieve the above object, the present invention provides a tool sleeve for accommodating a machining tool, comprising a tool sleeve body, a tool locking means, and a pressing member. The tool sleeve body has a receiving space and at least one radial hole, and the tool sleeve body has a mounting surface on its outer circumferential surface. The receiving space can accommodate the machining tool, and the at least one radial hole is disposed radially from the mounting surface and communicates with the receiving space. The tool locking means includes at least one spring and at least one steel ball, which are disposed in the at least one radial hole in the tool sleeve body. One end of the at least one spring abuts against the at least one steel ball, causing a portion of the surface of the at least one steel ball to protrude into the receiving space. The pressing member is fixedly connected to the tool sleeve body. The pressing member has a pressing surface that contacts the mounting surface of the tool sleeve body. The other end of the at least one spring abuts against the pressing surface.

[0006] In one embodiment, the pressing part comprises an elongated steel strip having a rearwardly facing outer surface and an inner surface, the inner surface constituting the pressing surface, and the tool sleeve comprises fastening means for fixedly connecting the steel strip to the tool sleeve body, the steel strip surrounding the tool sleeve body.

[0007] In one embodiment, the tool sleeve body has an annular groove on its outer circumferential surface, the annular groove having a groove bottom that forms the mounting surface, and the steel strip is positioned in the annular groove and surrounds the tool sleeve body. [Effects of the Invention]

[0008] The effect of the present invention is that a spring having a relatively long length is selected as part of the tool locking structure based on a tool sleeve of the same specification, and when the spring is subjected to a pushing force, the relatively long length of the spring can effectively distribute the pushing force, thereby extending the service life of the spring.

[0010]

[0016] The tool sleeve for accommodating a machining tool according to the present invention, when having the same outer diameter as a conventional tool sleeve, can effectively distribute the force of the spring when it is deformed by being pressed, thereby reducing the load on the spiral winding of the spring and thereby extending the service life of the spring. To more clearly explain the present invention, several preferred embodiments will be described below with reference to the drawings. As shown in Figures 1 to 4, a tool sleeve 100 for accommodating a machining tool 200 according to a first preferred embodiment of the present invention, which can achieve the above-mentioned object, includes a tool sleeve body 10, a tool locking means 20, a pressing part, and a fixing means.

[0011] 5 and 6, the tool sleeve body 10 is generally cylindrical and has a conical hole 11 and an axial hole 12 that communicate with each other. The conical hole 11 and the axial hole 12 together form the receiving space defined in the present invention. The axial hole 12 is composed of an inner hole portion 12a and an outer hole portion 12b. The inner hole portion 12a communicates with the conical hole 11 and has a smaller diameter than the outer hole portion 12b. The tool sleeve body 10 forms a contact surface 13 at the connection portion between the inner hole portion 12a and the outer hole portion 12b, and a fitting groove 14 is recessed into the hole wall of the outer hole portion 12b. If a virtual axis L is defined that passes through the centers of the conical hole 11 and the axial hole 12, the machining tool 200 can advance through the conical hole 11 along the axis L. The processing tool 200 according to this embodiment may be a tool rod to which a cutting tool can be connected.

[0012] The tool sleeve body 10 has a mounting surface 15 on its outer circumferential surface and at least one radial hole 16 extending radially from the mounting surface 15 and communicating with the axial bore 12. As shown in FIGS. 2 and 6, the tool sleeve body 10 has an annular groove 17 recessed into its outer circumferential surface on the opposite side from the side where the machining tool 200 is inserted into the conical bore 11. The annular groove 17 defines the mounting surface 15 at its bottom. The mounting surface 15 is comprised of an arc-shaped portion 15a and a flat-cut portion 15b. The at least one radial hole 16 is plural in number, is equally spaced radially from the arc-shaped portion 15a, and communicates with the internal bore portion 12a of the axial bore 12. It should be noted that the number of radial holes 16 may be increased or decreased depending on the needs of other applications.

[0013] The tool locking means 20 includes at least one spring 21, at least one steel ball 22, an unlocking element 23, and an obstructing element 24. In this embodiment, the number of springs 21 and steel balls 22, including the number of radial holes 16, is plural, and one radial hole 16 accommodates one spring 21 and one steel ball 22. The unlocking element 23 is a circular tube that can move along the axis L through the axial hole 12 of the tool sleeve body 10. The unlocking element 23 includes a closed end 231, an internal recessed hole 232, at least one side open hole 233, and an annular partition 234. The at least one side open hole 233 is located in the tube wall and communicates with the internal recessed hole 232. The number of side open holes 233 in this embodiment is the same as the number of radial holes 16. The annular partition 234 is formed to protrude outward from the tube wall. The obstructing part 24 is a C-shaped engaging part, and when the unlocking part 23 is placed in the axial hole 12, it is fitted into the fitting groove 14 in the tool sleeve body 10, and is thereby connected to be located at the position of the outer hole part 12b. When the unlocking part 23 moves, its annular partition 234 can come into contact with the contact surface 13 or the obstructing part 24. The former limits the stroke of the unlocking part 23 being pushed outward, while the latter prevents the unlocking part 23 from falling off the tool sleeve body 10.

[0014] The pressing element is fixedly connected to the tool sleeve body 10 and has a pressing surface that contacts the mounting surface 15 of the tool sleeve body 10. The pressing element serves to restrict the spring 21 and steel ball 22 to the radial hole 16 of the tool sleeve body 10. In this embodiment, the pressing element achieves this purpose in combination with the fixing means. Referring to FIGS. 2 to 4, the pressing element in this embodiment is an elongated steel strip 30. The steel strip 30 has a rearward-facing outer surface 30a and an inner surface 30b, with the inner surface 30b forming the pressing surface. The width of the steel strip 30 corresponds to the width of the annular groove 17 of the tool sleeve body 10. The steel strip 30 has bent pressing portions 31 at both ends, each with a through-hole 31a.

[0015] In this embodiment, the fixing means includes two fixing parts 40 and two fixing holes 18 drilled vertically downward from the flat cut portion 15b of the tool sleeve body 10. Each of the two fixing parts 40 has a body portion 41 and a head portion 42 located at one end of the body portion 41. When the steel strip 30 is placed in the annular groove 17 and surrounds the tool sleeve body 10, the body portion 41 of each fixing part 40 passes through the through holes 31a of the steel strip 30 and is inserted into the corresponding fixing hole 18. As a result, the head portion 42 of each fixing part 40 presses against the outer surface 30a of the steel strip 30, and each pressing portion 31 of the steel strip 30 is stretched flat against the flat cut portion 15b of the mounting surface 15. Thus, the steel strip 30 achieves the purpose of fixing and connecting the tool sleeve body 10 in a surrounding form. Furthermore, the steel strip 30 is positioned in the annular groove 17 and will not fall out of the tool sleeve body 10, effectively ensuring the positions of the spring 21 and the steel ball 22.

[0016] As shown in Figures 3 and 4, after assembly, one end of the spring 21 abuts against the inner surface 30b (i.e., the pressing surface) of the steel strip 30, and the other end abuts against the steel ball 22. The elastic force of the spring 21 urges a portion of the steel ball 22 to pass through the side open hole 233 of the unlocking part 23, and a portion of the surface of the steel ball 22 protrudes into the inner recessed hole 232 (corresponding to protruding into the receiving space). When the machining tool 200 is housed in the tool sleeve 100, one end 201 of the machining tool 200 protrudes into the inner recessed hole 232 of the unlocking part 23. The steel balls 22 press against the abutment surface 201a of the end 201, so that the machining tool 200 is stably attached and inserted into the tapered hole 11 of the tool sleeve body 10, thereby achieving the purpose of fixing and locking the machining tool 200. On the other hand, when a force is applied to the closed end 231 of the unlocking part 23, the unlocking part 23 is pushed in the direction of the processing tool 200, and the unlocking part 23 forces the plurality of steel balls 22 to move radially outward while pressing the springs 21 so as to deform, so that when the plurality of steel balls 22 leave the movement path of the end 201 but are not in contact with the abutment surface 201a of the end 201, the processing tool 200 can be easily removed to achieve the purpose of unlocking.

[0017] The above has been a description of the construction and use of the tool sleeve 100. The following describes how the design of the present invention overcomes the problem of spring fatigue.

[0018] The pressing part of this embodiment uses a tough steel strip 30. This eliminates the need to lock a screw into the radial hole 16 of the tool sleeve body 10 to prevent the spring 21 and steel ball 22 from slipping out, even if a conventional tool sleeve has the same outer shape. This eliminates the problem of only being able to use a relatively short spring because the screw occupies part of the space in the radial hole in the conventional technology. Therefore, the present invention allows for the selection of a relatively long spring. In other words, the number of turns of the helical winding of the spring 21 of this embodiment is relatively large. When the spring 21 is subjected to a pushing force and the helical winding is twisted, the pushing force can be effectively distributed among the multiple helical windings, reducing the load on each helical winding and extending the service life of the spring 21. This ultimately improves the stability of the tool sleeve 100 when the processing tool 200 is housed within the tool sleeve 100. Furthermore, in the form in which the tool sleeve body 10 is covered with one steel strip 30, not only can the assembly efficiency be effectively improved, but also the force of the spring 21 pressing the steel ball 22 in each radial hole 16 is uniform.

[0019] The above-mentioned fastening means mainly achieves the purpose of connecting the steel strip 30 and the tool sleeve body 10 through the fastening part 40. To enhance the effect of fastening the tool sleeve body 10 with the fastening part 40, the body part 41 of the fastening part 40 is designed to have an interference fit with the fastening hole 18. Preferably, the body part 41 has an annular deformation part 41a, and the outer diameter of the annular deformation part 41a is larger than the diameter of the fastening hole 18. In a specific embodiment, the fastening part 40 is a blind rivet. When the mandrel of the blind rivet is removed, the body part of the blind rivet is forced to expand and deform from the inside to the outside, and the expanded and deformed portion of the blind rivet forms the annular deformation part 41a, thereby firmly fastening the tool sleeve body 10 with the fastening part 40. In another specific application example, the fastening part 40 may be a bolt. The fastening hole 18 is a screw hole. The threaded connection means achieves the purpose of connection and fastening. Although two fastening pieces 40 and two fastening holes 18 are shown in the example, only one fastening piece 40 and one fastening hole 18 may be provided in practice. Based on this, the length of the steel strip 30 must be greater than the circumferential length of the outer surface of the tool sleeve body 10. As shown in FIG. 7, the pressing portions 31 at both ends of the steel strip 30 overlap each other, and one fastening piece 40 simultaneously passes through the through-holes 31a of the pressing portions 31, and the body portions 41 of the fastening pieces 40 are directly inserted into the corresponding fastening holes 18. This achieves the purpose of firmly fastening the steel strip 30 to the tool sleeve body 10.

[0020] 8 to 10 show a tool sleeve 100A according to a second preferred embodiment of the present invention. The tool locking means 20A of the tool sleeve 100A has the spring 21 and steel ball 22 similar to those of the tool locking means 20 according to the first preferred embodiment, but does not have the unlocking part 23 and the blocking part 24. Therefore, the tool sleeve body 10A of the tool sleeve 100A also does not have a corresponding structure for attaching the unlocking part 23 and the blocking part 24. Other than that, the tool sleeve body 10A has the same structures and features as the tapered hole 11, axial hole 12, mounting surface 15, multiple radial holes 16, annular groove 17, and two fixing holes 18 of the above-mentioned embodiment, and also has the spring 21 and steel ball 22 placed in the radial hole 16. The difference from the first preferred embodiment is that the tool sleeve body 10A of this embodiment further includes dividing grooves 19, and the steel strip 30A is folded inward at the ends of each pressing portion 31 to form mating pieces 31b. The dividing grooves 19 are installed radially apart from the midpoint between the two fixing holes 18 and divide the mounting surface 15. When the steel strip 30A surrounds the tool sleeve body 10A, each mating piece 31b is inserted into the dividing grooves 19 at the same time. As described above, when the fixing part 40 passes through the through hole 31a of the steel strip 30A and passes through the fixing hole 18 in the tool sleeve body 10A, not only can the steel strip 30A be firmly fixed to the tool sleeve body 10A, but also, by attaching each fitting piece 31b to the side wall of the dividing groove 19, the pulling force that is likely to be generated by the recovery characteristics of the steel strip 30A can be appropriately offset, thereby ensuring that the shape of the through hole 31a in the steel strip 30A is not deformed. Note that the arrangement relationship between the dividing groove 19 and the fitting pieces 31b can be applied to the configuration of the tool sleeve 100 according to the first preferred embodiment of the present invention.

[0021] The fixing means for the tool sleeve 100 (100A) according to the first and second preferred embodiments described above is such that the fixing part 40 passes through the through-hole 31a in the steel strip 30 (30A) and the fixing hole 18 in the tool sleeve body 10 (10A), thereby achieving the purpose of fixedly connecting the steel strip 30 (30A) to the tool sleeve body 10 (10A). In addition to the above-mentioned configurations, the fixing means employed for the tool sleeve 100B according to the third preferred embodiment of the present invention is spot welding or pressure welding. As shown in FIGS. 11 and 12 , the tool sleeve body 10B of the tool sleeve 100B has a recessed portion D, and the steel strip 30B surrounds the tool sleeve body 10B and is positioned in the annular groove 17. The steel strip 30B has an overlapping portion O formed by overlapping both ends of the steel strip 30B. A spot welding or pressure welding machine enters the recessed portion D and performs welding or pressure heating of the overlapping portion O to form a fixed connection at both ends of the steel strip 30B.

[0022] As can be seen from the above description, as long as the tool sleeve body can be covered with a single steel strip and the spring and steel balls can be constrained in the radial holes, the fixing means should not be limited to a design that combines a fixing hole with a fixing part, or to technical means such as spot welding or pressure welding.

[0023] In each of the above embodiments, the annular groove is recessed on the outer circumferential surface of the tool sleeve body to prevent the steel strip from slipping out of the tool sleeve body. However, it should be noted that the annular groove is not absolutely necessary, provided that the steel strip is prevented from sliding freely. For example, a small stopper protruding from the outer circumferential surface of the tool sleeve body can be used to restrict the steel strip from moving. Furthermore, the annular groove in each of the above embodiments has a flat cut portion at the bottom of the groove and a pressing portion at each end of the steel strip. The pressing portion can be used to attach the flat cut portion to the steel strip, allowing the next fixing component to be quickly positioned and fixed. In practice, even if the annular groove does not have a flat cut portion at the bottom or a pressing portion at each end, the function of fixing and connecting the fixing component is not affected.

[0024] The tool sleeve body in each of the above embodiments is generally cylindrical, and therefore includes an arc-shaped portion on the mounting surface that is installed along the outer periphery of the tool sleeve body. However, in reality, not all tool sleeve bodies are cylindrical. For example, as shown in the configuration of previously disclosed Taiwan Patent No. M563937, the portion where the spring and steel ball are installed does not have a cylindrical characteristic. However, in the equivalent substitution of the present invention, as long as the mounting surface is installed on the outer periphery of the tool sleeve body, whether it is installed continuously or separately, it should be within the scope of the present invention.

[0025]

[0013] As described above, the present invention uses a single steel strip to cover the tool sleeve body and restricts the spring and steel balls to the radial holes, thereby improving the prior art's problems of requiring multiple screws to prevent the steel balls and springs from falling out of all the radial holes, resulting in laborious assembly and uneven pressure applied by the springs to the steel balls. Furthermore, since the prior art's problem of screws occupying the space of the radial holes can be eliminated, a spring with a relatively long length can be selected, reducing the load on the spiral winding, thereby extending the service life of the spring and improving stability when the tool sleeve is used to store the machining tool.

[0026] The above description is merely a preferred embodiment of the present invention, and any equivalent replacements made by applying the claims together with the specification of the present invention should be included in the scope of the claims of the present invention.
