Description

Technical Field

[0001] This invention relates to a tool module, and more specifically, to a tool module that allows for easy tool replacement and rapid, precise positioning. Background Technology

[0002] Due to design requirements, product surfaces often require surface cutting to create necessary grooves or to cut thin workpieces. Among various processing tools, disc cutters, with their adjustable rotation speed, can achieve cutting or slitting operations. Because cutting is extremely fast and precise, they can accurately create surface grooves or cutting grooves of the required dimensions on the workpiece surface.

[0003] For disc cutting machines, the existing structural design makes it difficult to change tools, and after tool replacement, recalibration and positioning are also challenging. Tool calibration and positioning are extremely cumbersome and time-consuming, hindering the production capabilities of disc cutting machines. In particular, some machine designs restrict the use of tools to a fixed length, limiting the range of processing applications. Furthermore, while some machine designs allow for tool extension and retraction adjustment, the amount of extension cannot be precisely adjusted, increasing errors in product processing.

[0004] When changing blades, the blades are not easily secured, which can easily lead to them falling off, causing damage or accidental injury to the operator, posing a safety risk. Therefore, improving the blade design of rotary cutting machines to facilitate blade replacement, reduce blade drops, enable quick and accurate positioning, and allow for precise adjustment of the elongation amount has become a pressing issue for those skilled in the art. Summary of the Invention

[0005] One objective of this invention is to provide a tool module that is applicable to various types of rotary cutting machines or blade cutting machines. It allows operators to quickly change tools, quickly and accurately position tools, and precisely adjust and position the extension of the tools, thereby increasing the processing flexibility and accuracy of the cutting machine.

[0006] One embodiment of the present invention provides a tool module including a tool head and at least one tool unit. The tool head has a base and at least one positioning groove, which is arranged along the edge of the base. The positioning groove is formed by two adjacent sidewalls, each sidewall protruding from the base. The positioning groove has a first spacing and a second spacing, the second spacing being closer to the edge of the base than the first spacing, and the first spacing being greater than the second spacing. The tool unit is correspondingly disposed within the positioning groove. Each tool unit has a first width and a second width, the first width being greater than the second width.

[0007] Another embodiment of the present invention provides a tool module including a tool head and a plurality of tool units. The tool head has a base and a plurality of positioning slots, which are spaced apart along the edge of the base. Each positioning slot is formed by two adjacent sidewalls, and each sidewall protrudes from the base. Each positioning slot has a first spacing and a second spacing, the second spacing being closer to the edge of the base than the first spacing, and the first spacing being greater than the second spacing. Each tool unit is correspondingly disposed within a positioning slot. Each tool unit has a first width and a second width, and the first width is greater than the second width.

[0008] Compared to conventional technology, the tool module of this invention designs the positioning groove as an inverted trapezoidal groove, making the first spacing of the positioning groove greater than the second spacing. The tool unit is also designed with an inverted trapezoidal structure, making the first width of the tool unit greater than the second width, corresponding to the first and second spacings of the positioning groove, respectively. Therefore, the tool unit can slide stably into the positioning groove, reducing the possibility of the tool unit falling out. Furthermore, the positioning groove and the tool unit each have a pair of corresponding side grooves and a pair of side protrusions on both sides. Utilizing a design that is narrower at the top and wider at the bottom, the tool unit can slide more securely into the positioning groove, further reducing the probability of the tool unit falling out. Therefore, the tool unit can be quickly and accurately positioned within the positioning groove, and the elongation of the tool unit can be precisely adjusted and positioned. This improves the machining flexibility and accuracy of the tool module during processing. Attached Figure Description

[0070] Figure 1 This is a three-dimensional structural diagram of a tool module according to one embodiment of the present invention. Figure 2 This is a top view of a tool module according to one embodiment of the present invention. Figure 3 This is a front view schematic diagram of a tool module according to one embodiment of the present invention. Please refer to... Figures 1 to 3 To highlight the technology and advantages of this invention, the dimensions, proportions, and structural representations in the illustrations will be appropriately adjusted to facilitate a clearer understanding of the invention's purpose and advantages. The tool module 10 of this invention is for illustrative purposes only and does not represent its actual dimensions and configuration. Those skilled in the art can appropriately modify the structural design of the tool module 10 without departing from the spirit and scope of this invention, achieving the same effects. The tool module 10 of this invention is applicable to various cutting machines or cutters; a suitable tool module 10 can be selected according to processing requirements, without limiting the application scope of this invention.

[0071] Please refer to Figures 1 to 3 The tool module 10 of the present invention includes at least a tool head 100 and a tool unit 200. The tool unit 200 of the present invention can use at least one tool unit, that is, one or more tool units. The number of tool units 200 used can be adjusted according to needs and is not limited. In this embodiment, only eight tool units 200 are used as an example, and the number used is not limited; for example, 1 to 32 can be used, but there is no limitation.

[0072] Please refer to Figures 1 to 3The tool unit 200 can be disposed on the tool disc 100 via the positioning slot 120. In a preferred embodiment, the disposal method includes detachable disposal and movable disposal. The number of tool units 200 may be less than or equal to the number of positioning slots 120. In this embodiment, eight tool units 200 and eight positioning slots 120 are used as examples, but their number is not limited. For example, in a variant embodiment, only four tool units 200 may be used in combination with the eight positioning slots 120, and the combination form is not limited. The tool disc 100 has a central portion 114, and the tool units 200 are symmetrically distributed around the central portion 114. The tool units 200 are spaced apart along the edge 112 of the tool disc 100, such as... Figure 2 As shown in Figure 4, the number of tool units 200 is not limited to an even number, but can also be an odd number, and they are evenly and symmetrically distributed around the central part 114, which will not be elaborated further here.

[0073] Figure 4A This is a three-dimensional structural diagram of a cutter head according to one embodiment of the present invention. Figure 4B This is a top view of a partially enlarged area of ​​the cutter head according to one embodiment of the present invention. Figure 4C This is a magnified front view of a portion of the cutter head according to one embodiment of the present invention. (See reference) Figures 4A to 4C The cutter head 100 includes at least a base 110, a positioning groove 120, and a retaining portion 130. The base 110 is used to fix the cutter unit 200. In this embodiment, the base 110 is illustrated by a circular base, but it is not limited to a circle. For example, an octagonal base or a hexagonal base can also be used instead, but it is not limited to this.

[0074] Please refer to Figures 4A to 4C The base 110 has at least one positioning groove 120, that is, one or more positioning grooves 120. The positioning groove 120 is disposed adjacent to the edge 112 of the base 110. If there are multiple positioning grooves 120, these positioning grooves 120 are spaced apart along the edge 112 of the base 110. Each positioning groove 120 is formed by the sidewalls 136 of two adjacent retaining portions 130, and each sidewall 136 protrudes from the base 110. Each retaining portion 130 is coupled to the base 110. The retaining portion 130 and the base 110 can be integrally formed, or they can be separate components coupled by welding or screws. The coupling method is not limited. The base 110 and the retaining portion 130 can be made of, for example, stainless steel, or other suitable materials, but are not limited.

[0075] In this embodiment, eight positioning slots 120 and eight retaining portions 130 are used as examples, but their number is not limited. For example, in a variant embodiment, four positioning slots 120 and eight retaining portions 130 can be used together, and the combination is not limited. The base 110 has a central portion 114 at its center, and the central portion 114 can be connected to a rotating shaft (not shown) as a bearing for the base 110. For example, four locking screws (such as...) can be added around the central portion 114. Figure 4A The connection between the central part 114 and the rotating shaft (as shown) increases the torque capacity of the connection. The number of locking screws is not limited to four and can be adjusted as needed. A drive mechanism such as a motor (not shown) drives the rotating shaft, causing the central part 114 and the base 110 to rotate, achieving the purpose of rotary cutting. This is well known to those skilled in the art and will not be described further here.

[0076] In one embodiment, from Figure 5B Viewed from above, each positioning slot 120 can be designed as an inverted trapezoid, which helps the tool unit 200 to slide quickly and accurately into and lock into the positioning slot 120. When the base 110 is upright, this reduces the time required for the tool unit 200 to slide into the positioning slot 120 (e.g., Figure 9 As shown), the problem of accidental fall along the vertical direction (i.e., the D1 direction) occurs. Each positioning groove 120 has a first spacing S1 and a second spacing S2, which are, for example, perpendicular to the radial direction of the base 110. The first spacing S1 is adjacent to the center 114, and the second spacing S2 is adjacent to the edge 112 of the base 110, and the first spacing S1 is larger than the second spacing S2, forming the aforementioned inverted trapezoidal configuration. The positioning groove 120 includes two extension grooves 122 extending outward from both sides. The upper edges of both sides of the positioning groove 120 form two acute angles α with the vertical direction (i.e., radial direction) of the second spacing S2, such as... Figure 4B As shown. The included angle α can be between 1 and 15 degrees, and preferably between 1 and 10 degrees, but is not limited thereto. In addition, the first spacing S1 and the second spacing S2 can be the spacing measured at different positions of the top opening of the positioning groove 120, or the spacing measured at different positions of the bottom of the positioning groove 120.

[0077] refer to Figures 4A to 4C Each positioning groove 120 may optionally have a guide rail bottom groove 128 arranged radially along the base 110 at the bottom center for fixing the guide rail 300, such as... Figure 8 As shown. For example, two locking holes 1282 can be selectively provided at the bottom of the guide rail bottom groove 128 to enhance the fixation of the guide rail 300. Two rows of positioning holes 150a can be arranged on both sides of the guide rail bottom groove 128, for example, a total of 6, but not limited to this. After the tool unit 200 slides into the positioning groove 120, positioning screws 250c (such as...) can be used to... Figure 10 (As shown) with positioning hole 250b (e.g.) Figure 10 As shown, the tool unit 200 is locked in place by the positioning hole 150a.

[0078] refer to Figures 4A to 4C Positioning portions 132 may be selectively provided on the retaining portions 130 on both sides of each positioning groove 120. In one embodiment, the positioning portion 132 is, for example, a positioning ruler. When the tool unit 200 slides into the positioning groove 120, it can be precisely positioned using the positioning portion 132, with a positioning accuracy of, for example, 1 millimeter (mm) or 0.1 mm, but not limited thereto. In a variation embodiment, if only a few positioning positions are needed, positioning marks can be used instead to achieve a rapid positioning effect. In another variation embodiment, if a higher degree of positioning accuracy is required, a grating digital sensor can be used instead of a positioning ruler to further improve positioning accuracy.

[0079] In one embodiment, such as Figure 4B As shown, the side walls on both sides of the inverted trapezoidal positioning groove 120 can be designed as vertical surfaces (not shown). In another embodiment, as... Figure 4A and Figure 4C In the embodiment shown, the trapezoidal positioning groove 120 can be further designed as a dovetail-shaped positioning groove 120 with inclined sidewalls 136, improving the locking ability of the tool unit 200 sliding into the positioning groove 120 in the D3 direction, and further reducing the problem of the tool unit 200 accidentally falling due to tilting. The positioning groove 120 can be inclined inward by the two inclined protrusions 134 of the holding portions 130 on both sides to form inclined sidewalls 136, and correspondingly, auxiliary side grooves 124 are formed on both sides of the positioning groove 120 (such as... Figure 4C (As shown). The inwardly inclined side groove 124 is used in conjunction with the side protrusion 214 of the tool unit 200 (as shown). Figure 5C As shown, this configuration further prevents the tool unit 200 from falling off due to tilting along the D3 direction. Taking the position at the second spacing S2 as an example, the bottom spacing S2B of the dovetail-shaped positioning groove 120 is greater than the top spacing S2U. Therefore, after the tool unit 200 slides into the positioning groove 120, the oblique protrusions 134 on both sides engage the side protrusions 214 on both sides of the tool unit 200. The side walls of the side grooves 124 on both sides of the positioning groove 120 form an acute angle θ with the vertical normal direction of the base 110 surface, such as... Figure 4C As shown. The included angle θ can be between 1 degree and 30 degrees, and preferably between 1 degree and 20 degrees, but is not limited thereto. When the cutter head 100 is vertically erected, and the cutter unit 200 slides vertically into the positioning groove 120, as... Figure 9 As shown, this can reduce the tipping and falling of the tool unit 200 along the vertical direction (i.e., the D3 direction) of the base 110 surface.

[0080] Figure 5A This is a three-dimensional structural diagram of a cutting tool unit according to one embodiment of the present invention. Figure 5B This is a top view of a tool unit according to one embodiment of the present invention. Figure 5C This is a front view structural diagram of a tool unit according to one embodiment of the present invention. Figure 6 This is an exploded view of a tool unit according to one embodiment of the present invention. Please refer to... Figures 5A to 6 The tool unit 200 includes at least a tool holder 210, a tool 220, and a tool cover 230. The tool 220 may also be referred to as the tool body. The tool 220 is sandwiched between the tool holder 210 and the tool cover 230, and the tool 220 is fixed by the tool holder 210 and the tool cover 230. For example, a tool recess 216 for accommodating the tool 220 is designed in the center of the tool holder 210. The tool holder 210 and the tool cover 230 are respectively designed with a set of locking holes 242a and a set of locking holes 242b, corresponding to a set of locking screws 242c. For example, four locking holes 242a are designed at the four corners of the tool holder 210, and correspondingly, four locking holes 242b are designed at the four corners of the tool cover 230. The locking screws 242c pass through the locking holes 242b and are locked with the locking holes 242a to fix the tool 220, but this is not limited to this. To ensure the tool 220 is fixed, three locking holes 244b can be designed in the center of the tool cover 230. Locking screws 244c are passed through the locking holes 244b to secure the top surface of the tool 220. If necessary, locking screws 246c can be selectively designed on the side of the tool 220, passing through locking holes (not shown), to secure the side of the tool 220. When the base 110 rotates, it can stably drive the tool 220 to rotate along with it.

[0081] Please refer to Figures 5A to 6 At the bottom of the tool holder 210, opposite to the tool groove 216, a guide rail top groove 218 can be designed to cooperate with the guide rail 300 for sliding. When the tool unit 200 slides into the positioning groove 120, the guide rail 300 and the guide rail top groove 218 can cooperate to assist the tool holder 210 of the tool unit 200 to slide along the guide rail 300, thereby improving the positioning capability of the tool unit 200. After the tool unit 200 slides into the positioning groove 120, it can be precisely positioned using the positioning part 132. The tool unit 200 further includes a pair of positioning holes 250b and a pair of positioning screws 250c located on both sides of the tool 220. Each positioning hole 250b includes an elongated positioning hole 250b1 on the tool holder 210 and an elongated positioning hole 250b2 on the tool cover 230. The elongated design can extend in a direction parallel to the guide rail top groove 218, for example. Then, the positioning screws 250c on both sides of the tool 220 (such as...) can be used to... Figure 10(As shown) Passing through the elongated positioning hole 250b2 on the cutter cover 230 and the elongated positioning hole 250b1 on the cutter holder 210, and the positioning hole 150a on the base 110 (as shown) Figure 4A As shown, the tool unit 200 is precisely positioned and fixed by screw locking the paired parts.

[0082] Please refer to Figures 5A to 6 The cutting tool 220 includes at least a blade 222 and a cutting tip 224. The blade 222 has an insert portion 222a and an extension portion 222b. The insert portion 222a is sandwiched between the tool holder 210 and the tool cover 230, and the extension portion 222b protrudes from the tool holder 210 and the tool cover 230. After the cutting tool unit 200 is fixed to the positioning groove 120, the cutting tip 224 protrudes radially from the edge 112 of the base 110, as shown below. Figure 10 As shown. The cutting head 224 is fixed to the front end of the extension 222b and is used to cut or cut off the workpiece, forming the desired cutting pattern on the surface of the workpiece. The cutting head 224 can be made of a hard material, such as stainless steel, high carbon steel, tungsten, tungsten steel, diamond, etc., but is not limited to these. It can be used to process materials such as wood, plastic, glass, metal, ceramics, etc., without limitation.

[0083] In one embodiment, from Figure 5B Viewed from above, the tool holder 210 of the tool unit 200 of this invention adopts an inverted trapezoidal design. The two side walls of the inverted trapezoidal tool holder 210 can be designed as vertical surfaces (not shown), corresponding to the inverted trapezoidal positioning groove 120 (not shown). The tool holder 210 of the tool unit 200 has extensions 212 on both sides, corresponding to the extension grooves 122 of the positioning groove 120. When the tool disc 100 is vertically erected, and the tool unit 200 slides vertically into the positioning groove 120, the extensions 212 on both sides can be engaged in the extension grooves 122, reducing the probability of the tool unit 200 falling vertically along the D1 direction. Figure 9 As shown.

[0084] Each tool unit 200 has a tool holder 210 with a length L and a first width W1 and a second width W2, which are perpendicular to the length L. The first width W1 is away from the tool tip 224 of the tool 220, and the second width W2 is adjacent to the tool tip 224. The first width W1 is greater than the second width W2, forming an inverted trapezoidal configuration. The first width W1 can be calculated from the width of the bottom edge. If there are chamfered corners on both sides of the bottom edge, such as... Figure 5B As shown, the widest part can be taken as the first width W1. The tool holder 210 includes two extensions 212 extending outwards from both sides. The upper edges of both sides of the tool holder 210 form two acute angles β with the vertical direction (i.e., the length direction) of the second width W2 with respect to the extensions 212, such as... Figure 5BAs shown. The included angle β of the extension 212 can be, for example, between 1 and 15 degrees, and preferably between 1 and 10 degrees, but is not limited thereto. The included angle β of the extension 212 can be less than or equal to the included angle α of the extension groove 122 to prevent the extension 212 from failing to slide smoothly into the extension groove 122. Positioning marks 211 can be selectively provided at the center position of the extensions 212 on both sides of the tool unit 200. After the tool unit 200 slides into the positioning groove 120, the positioning marks 211 can be used to assist the tool unit 200 in positioning with the positioning portions 132 on both sides of the positioning groove 120.

[0085] In one embodiment, from Figure 5B Viewed from above, the two side walls of the inverted trapezoidal tool holder 210 can be designed as vertical surfaces (not shown), corresponding to the inverted trapezoidal positioning groove 120 (not shown). Furthermore, in another embodiment, please refer to... Figures 5A to 6 In one embodiment, the trapezoidal tool holder 210 can be further designed as a dovetail-shaped tool holder 210 with an inclined surface, corresponding to the dovetail-shaped positioning groove 120. This enhances the locking ability of the tool unit 200 when it slides into the positioning groove 120 in the D3 direction, further reducing the problem of the tool unit 200 accidentally falling off. The tool holder 210 has auxiliary side protrusions 214 on both sides, corresponding to the side grooves 124 on both sides of the positioning groove 120, which further prevents the tool unit 200 from falling off. Taking the second width W2 position of the dovetail-shaped tool holder 210 as an example, the bottom width W2B of the tool holder 210 is greater than the top width W2U. Therefore, after the tool unit 200 slides into the positioning groove 120, the inclined protrusions 134 above the side grooves 124 on both sides lock the side protrusions 214 on both sides of the tool holder 210, such as... Figure 3 As shown. When the cutter head 100 is vertically erected, and the cutter unit 200 slides vertically into the positioning groove 120, as... Figure 9 As shown, this can reduce the tipping and falling of the tool unit 200 along the vertical direction (i.e., the D3 direction) of the base 110 surface. The side walls of the side protrusions 214 on both sides of the tool holder 210 form an acute angle δ with the vertical direction of the bottom surface of the tool holder 210, as shown. Figure 5C As shown. The included angle δ of the side protrusion 214 can be between 1 degree and 30 degrees, and preferably between 1 degree and 20 degrees, but is not limited thereto. The included angle δ of the side protrusion 214 can be less than or equal to the included angle θ of the side groove 124 to prevent the side protrusion 214 from being unable to slide smoothly into the side groove 124.

[0086] Figures 7 to 10 This is a schematic diagram illustrating the assembly process of a tool module according to one embodiment of the present invention. The tool module 10 is typically used vertically for machining processes. Please refer to... Figure 7 When assembling or replacing the tool unit 200, the tool head 100 can be erected vertically for easy assembly by the operator. Please refer to [reference needed]. Figure 8Next, a guide rail 300 is installed in each guide rail groove 128, and the guide rail 300 is fixed using the locking holes 1282 at the bottom of the guide rail groove 128. Please refer to... Figure 9 The assembled tool unit 200 is slid into the positioning slot 120. With the assistance of the guide rail 300, the tool unit 200 can be positioned horizontally (i.e., in the D2 direction). Simultaneously, the tool unit 200 can be positioned at a circumferential angle, for example, at 180 degrees, to prevent positioning errors caused by rotational offset of the base 110. Please refer to [reference needed]. Figure 10 Finally, the positioning part 132 and the positioning screw 250c are used to position the tool unit 200 radially, for example, in the vertical direction (i.e., the D1 direction), to determine the distance between the tool tip 224 and the center of the base 110's rotation axis. Afterwards, the base 110 can be rotated 45 degrees to assemble and position the next tool unit 200. Once all tool units 200 are installed, the tool tips 224 of all tool units 200 are accurately positioned, maintaining the same distance from the center of the rotation axis. This ensures that the tool tips 224 achieve uniform and good machining results when the base 110 rotates.

[0087] Figure 11 This is a top view of a tool module according to one embodiment of the present invention, showing the tool holder of the tool unit pushed down to its lower limit point. The second width W2 of the tool holder 210 can be designed to be equal to or less than the second spacing S2 of the positioning groove 120, and the first width W1 of the tool holder 210 can also be designed to be equal to or less than the first spacing S1 of the positioning groove 120. The first width W1 of the tool holder 210 can be designed to be greater than the second spacing S2 of the positioning groove 120, preventing the tool unit 200 from sliding vertically downwards and out of the positioning groove 120. In one embodiment, the second width W2 is designed to be equal to the second spacing S2, and the outer surface of the tool holder 210 can be approximately flush with the edge 112 of the base 110, so that the tool holder 210 is secured to the edge 112 of the base 110. In another embodiment, the second width W2 is designed to be slightly smaller than the second spacing S2, such as... Figure 11 As shown, the tool unit 200 can easily adjust its extension. The tool holder 210 of the tool unit 200 can be pushed upwards to its upper limit position (not shown), and the positioning mark 211 can be aligned with the upper edge scale of the positioning part 132 (i.e., the positioning ruler). The tool holder 210 of the tool unit 200 can also be extended downwards to its lower limit position, and the positioning mark 211 can be aligned with the lower edge scale of the positioning part 132 (i.e., the positioning ruler), so that the outer side of the tool holder 210 and the tool head 224 both extend outwards, protruding beyond the edge 112 of the base 110, achieving the maximum extension. The outward extension of the tool 220 of the tool unit 200 can improve the situation of insufficient machine travel for machining thin workpieces.

[0088] Furthermore, since the tool module 10 generates unnecessary heat at the machining location when machining the workpiece, a cooling unit (not shown) can be selectively added to the center 114 of the tool head 100. The cooling unit includes, for example, at least a connecting pipe, a connector, and spray pipes. The connecting pipe is centrally coupled to the connector, which is attached to the center 114. The spray pipes can be coupled to the four sides of the connector, allowing them to spray outwards. There can be, for example, four spray pipes, but this is not limited. Cooling gas or liquid can be introduced through the connecting pipe; the gas can be, for example, air, and the liquid can be, for example, water, but this is not a limitation. In a variant embodiment, the cooling unit can also be replaced by a cooling pipe, located near the machining area between the tool module 10 and the workpiece. The cooling pipe directly sprays cooling gas or liquid onto the machining area to remove the heat generated during machining, preventing heat from affecting the machining effect on the workpiece.

[0089] In summary, this invention provides a tool module in which the positioning groove and tool holder are designed in an inverted trapezoidal shape. This design ensures that the first distance between the positioning grooves is greater than the second distance, and that the first width of the tool holder is greater than the second width. This facilitates quick tool unit replacement and reduces the likelihood of tool units falling out. Furthermore, the positioning groove and tool holder can be designed in a dovetail shape, with a pair of corresponding side grooves and a pair of side protrusions on each side. This top-narrow, bottom-wide design allows the tool unit to slide more securely into the positioning groove, further reducing the chance of the tool unit tipping over and falling out. The positioning screws and holes allow for faster and more precise adjustment of the tool unit's elongation, ensuring consistent elongation and improving machining uniformity.
