Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a modular clamping aid for rotor slot processing tools. Background Art

[0002] The rotor slot is a gap between the rotor and the rotor for winding the excitation coil. The rotor slot is processed on a large horizontal car. The rotor is driven by the end chuck and rotates around its axis. The tool can move axially and radially with the tool holder body (moving according to the width and depth of the machined rotor slot).

[0003] Currently, large low-pressure rotors are still high-value-added products, requiring high manufacturing technology and long production cycles. Manufacturers worldwide are committed to improving their design and manufacturing capabilities. In particular, rotor slot machining presents numerous challenges. For example, the large aspect ratio of rotor slots makes chip removal difficult during machining and increases production cycles. Improving rotor slot machining techniques to shorten production cycles is crucial.

[0004] Traditional rotor slotting tools are integrated. When machining slots of varying widths, these tools require the entire blade to be disassembled and replaced, which is time-consuming, labor-intensive, and inefficient. Furthermore, slot expansion only involves single-sided cutting, resulting in low overall processing efficiency. Improving rotor slotting tool replacement efficiency is crucial. Summary of the Invention

[0005] In view of the above analysis, the present invention aims to provide a modular rotor slot tool to solve the problems of complicated assembly and disassembly and low working efficiency of existing rotor slot machining integrated tools.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] A modular clamping aid for rotor slot machining tools, comprising a blade body module mounted on a machine tool blade, a transition block module clamped on the blade body module, and a tool bar clamped on the transition block module;

[0008] A locking adjustment module is arranged between the blade body module and the machine tool blade, and the two are detachably fastened together by fasteners.

[0009] Furthermore, the blade body module has a main boss stop, and the shape of the main groove stop at the corresponding position on the machine tool blade is adapted to the main boss stop; a locking adjustment module is also provided at the junction surface of the main boss stop and the main groove stop.

[0010] Furthermore, the transition block module is provided with a secondary boss stop, and the blade body module is provided with a secondary groove stop; the knife rod is inserted into the transition block module and is detachably fastened to the transition block module through fasteners.

[0011] Furthermore, the locking adjustment module includes a positioning gasket, a locking key and a locking wedge.

[0012] Furthermore, the transition block module is installed at the front end of the blade body module.

[0013] Furthermore, a tool rod groove is provided on the transition block module for installing the tool rod.

[0014] Furthermore, the knife bar is a vertical handle type knife bar, a horizontal handle type knife bar, or a single-knife knife bar; the transition block module is a vertical handle type transition module, a horizontal handle type transition module, or a single-knife transition module.

[0015] Furthermore, the vertical handle transition module is provided with two tool bar grooves and two vertical handle tool bars.

[0016] Furthermore, the horizontal handle transition module is provided with a tool bar groove and two horizontal handle tool bars.

[0017] A method for using a modular clamping aid for a rotor slot machining tool, comprising the following steps:

[0018] S1: Select a toolholder based on the blade to be clamped; select a suitable transition block module based on the toolholder; select a matching blade body module based on the transition block module; select a locking adjustment module and fasteners suitable for clamping based on the blade body module and the machine tool blade to be used;

[0019] S2: Place the positioning gasket on the horizontal upper contact surface of the main groove stop of the machine tool blade; push the blade body module into the main groove stop of the machine tool blade and hook it so that the locking key slot is redundant; insert the locking key into the locking key slot;

[0020] S3: Push the blade body module further into the machine tool blade 1 so that the main groove stop and the main boss stop are in close contact. At this time, the locking keyway is closed; select a suitable fastener 6 to fasten the blade body module pushed into the machine tool blade 1;

[0021] S4: Place the locking wedge in the contact gap between the blade body module and the main boss stop that matches the main groove stop of the machine tool blade; select a suitable fastener 6 to fasten the locking wedge 5-3 to the blade body module 2;

[0022] S5: Sequentially adjust all fasteners in S3 and S4 to a locked state to maintain an interference fit between the blade body module and the machine tool blade;

[0023] S6: Push the auxiliary boss stop of the transition block module into the auxiliary groove stop of the blade body module; select appropriate fasteners to fasten the transition block module to the blade body module;

[0024] S7: Fix the tool bar to the transition block module.

[0025] S8: Fasten the blade to the front end of the shank through the fastener.

[0026] Compared with the prior art, the present invention can achieve at least one of the following technical effects:

[0027] 1. This invention modularizes the tool. When machining rotor slots of varying widths, depths, or shapes, individual modules can be replaced based on actual machining requirements (e.g., slot width, slot depth, etc.). Through standardized module interfaces, a modular rotor slot machining tool assembly and fixture is implemented, enabling a single machine tool blade to be matched with multiple blade body modules, a single blade body module to be matched with multiple transition block modules, and a single transition block module to be matched with multiple tool bars. This ensures that most tool changes do not require disassembly or installation of the blade body. This saves time and labor, and improves production efficiency.

[0028] 2. The tool bar is detachably mounted on the transition block, and the tool bar extension length can be adjusted by adjusting the bolt. When processing grooves of different depths or widths, only the tool bar extension length needs to be adjusted, without the need to replace the tool bar or other components, which greatly saves time and labor costs and improves processing efficiency.

[0029] 3. Two tool bars are set on the transition block module. Two blades with opposite processing directions are arranged through the tool bars on both sides of the transition block module, which can cut and expand the groove at the same time, greatly improving the processing efficiency.

[0030] 4. When using a double knife with a horizontal handle bar for slot expansion hour A spacer block is placed between the two toolholders on the transition block module to prevent toolholder movement when extended too far, while also limiting the machining volume. The spacer block also offsets the forces applied by the blades on both sides during simultaneous machining, improving blade stability and achieving greater machining accuracy.

[0031] Other features and advantages of the present invention will be described in the following description, and in part they may become apparent from the description or may be understood through implementation of the present invention. The purposes and other advantages of the present invention may be realized and obtained through the structures particularly pointed out in the written description and the accompanying drawings.

[0041] The modular clamping aid for rotor slot machining tools will be further described in detail below in conjunction with specific embodiments. These embodiments are only used for comparison and explanation purposes, and the present invention is not limited to these embodiments.

[0042] Attach Figures 1 to 5 Taking the technical solution of the present invention as an example, the following is a detailed description:

[0043] The accompanying drawings illustrate examples of using different transition block modules to mount a blade 8 on the same blade body module 2, and different blade body modules 2 mounted on the same machine tool blade 1. The modularized auxiliary tool of the present invention makes the tool clamping process universal and convenient, saving time and manpower.

[0044] During the machining process, the blade 8 and the auxiliary tool for mounting the blade 8 will bear the reaction force of the cutting force. The design of the auxiliary tool should consider that the mounting surface cannot be too simple to disperse or absorb part of the force, protect the tool and machine tool, and stabilize the machining quality. The modular clamping auxiliary tool for the rotor slot machining tool of the present invention and the mounting surface of the machine tool blade 1 fully consider the influence of the cutting force. The mounting surface (stop) is designed into multiple curved polygons. At the same time, considering the material properties of the machine tool blade 1 and the need for interference fit, a transition block module is designed between the blade body module 2 installed on the machine tool blade 1.

[0045] Example 1

[0046] This embodiment is a modular clamping aid for rotor slot machining tools. Figure 1 Specifically, it is a schematic diagram of a modular clamping aid for a serpentine slotting tool, i.e., a single-blade slotting tool. The transition block module shown in the figure is a single-blade transition module 3-3. A blade body module 2 is mounted on a machine tool blade 1, a single-blade transition block module 3-3 is clamped to the blade body module 2, and a tool bar is clamped to the transition block module; a tool having a blade 8 clamped thereon is mounted on the tool bar. The blade body module 2 is a plate having a main boss stop, preferably made of the same material as the machine tool blade 1, i.e., No. 45 ordinary carbon structural steel; the shape of the main groove stop at the corresponding position on the machine tool blade 1 is adapted to the main boss stop, and the blade body module 2 is positioned at the corresponding main groove stop of the machine tool blade 1 via a locking adjustment module 5. The two are detachably fastened together by fasteners 6.

[0047] In this embodiment 1, the preferred fastener 6 is a countersunk bolt or a screw.

[0048] In this embodiment 1, a stepped through hole is preferably provided on the blade body module 2, and a matching threaded hole is provided on the machine tool blade 1. Different blade body modules 2 have matching locking adjustment modules 5, and the two together form the main boss stop of the blade body module 2; the main groove stop on the machine tool blade 1 corresponds to it.

[0049] In this embodiment, the single-edge transition module 3-3 has multiple contact surfaces connected to the tool plate body module 2, and the multiple contact surfaces constitute the secondary boss stop of the single-edge transition module 3-3; the multiple contact surfaces on the tool plate body module 2 corresponding to the multiple contact surfaces of the single-edge transition module 3-3 constitute the secondary groove stop. One tool plate body module 2 can be matched with single-edge transition modules 3-3 of different shapes. Correspondingly, it is required that the size of the secondary boss stop of the single-edge transition module 3-3 be consistent with the shape of the secondary groove stop to form a modular interface. The single-edge transition module 3-3 is detachably and firmly connected to the front end of the tool plate body module 2 through the modular interface. Different types of single-edge transition modules 3-3 matched with the secondary groove stop of the same tool plate body module 2 have the same secondary boss stop. Optionally, in order to obtain a better stabilizing effect, the secondary groove stop is in a "U" shape.

[0050] In this embodiment, the solid support platform surrounded by the multiple contact surfaces of the single-edge transition module 3-3 constitutes the secondary boss stop of the single-edge transition module 3-3; correspondingly, the groove space formed by the multiple contact surfaces on the tool plate body module 2 corresponding to the secondary boss stop constitutes the secondary groove stop.

[0051] In addition, on the side surface of the single-edge transition module 3-3 outside the secondary boss stop (in Embodiment 1, it is the opposite side surface, and in other embodiments, it is on two adjacent side surfaces), there is a tool bar groove for installing the tool bar 4; the tool bar groove is in a燕尾式 or rail type; the structure of the tool bar 4 matches the tool bar groove. The tool bar 4 is nested and positioned in the tool bar groove; and there are at least 2 fastening through holes on the single-edge transition module 3-3 facing the tool bar groove, which are used to fasten the tool bar 4 in the tool bar groove on the single-edge transition module 3-3 through the fasteners 6; there are also screw holes on the tool bar 4 to fasten the cutting blade 8 on the tool bar 4. Generally, on the contact surface between the tool bar 4 and the cutting blade, there are respectively a cutting blade sinking groove and a cutting blade convex rib that match the width of the cutting blade for arranging the cutting blade 8, which plays a role in stabilizing and positioning the cutting blade and offsetting part of the cutting force.

[0052] More specifically, multiple fasteners 6 are arranged at positions corresponding to the extension direction of the tool bar in the tool bar groove of the transition block module. By adjusting the fastening positions of the multiple fasteners 6 and the fastening through holes, the extension length of the tool bar can be adjusted. When performing grooving processing with different depths or widths, only the extension length of the tool bar needs to be adjusted, and there is no need to replace the tool bar or other components, which greatly saves time costs and labor costs and improves processing efficiency.

[0053] Furthermore, refer to the appendix Figures 1-2After the main groove stop and the main boss stop are merged, a gap is left to form a locking keyway on the vertical or inclined contact surface, a positioning gap on the horizontal contact surface, and a contact gap (preferably a wedge-shaped gap) where the blade body module 2 at the upper end of the main boss stop is subjected to the greatest force. There can be one locking keyway or positioning gap, or two or more locking keyways or positioning gaps; the locking key 5-2 is inserted into the locking keyway, the positioning gasket 5-1 is placed in the positioning gap, the locking wedge block 5-3 is set in the wedge-shaped gap, and then the fastener 6 is used to lock the entire device.

[0054] The positioning gasket 5-1 is also preferably made of 45mm ordinary structural carbon steel. The positioning gasket 5-1 needs to be machined to a size that matches the blade body module 2 and has a roughness better than that of the machine tool blade 1. Positioning gasket 5-1 is located at the horizontal contact surface between the blade body module 2 and the machine tool blade 1. Firstly, the material ensures proper locking with the blade body module 2, protecting the machine tool blade 1 and the blade body module 2 from damage, extending service life, and saving costs. Secondly, considering that the gap size between blade bodies 2 of different specifications and the machine tool blade 1 varies, the use of positioning gasket 5-1, which requires less consumables and is easy to machine, easily achieves an interference fit when locking the blade body module 2 and the machine tool blade 1, thereby increasing the stability of the blade body module 2 on the machine tool blade 1. The size and shape of positioning gasket 5-1 are compatible with the contact surface between the blade body module 2 and the machine tool blade 1, and the thickness is compatible with the blade body module 2.

[0055] The locking wedge 5-3 has a polygonal cross-section, preferably a right-angled trapezoid, with a length that matches the thickness of the blade module 2. It is positioned where the blade module 2 experiences the greatest shear force when the rotor slot is being machined, preferably at the topmost locking keyway when the blade module 2 is engaged with the machine tool blade 1. Preferably, to enhance securement, the locking wedge 5-3 is interference-connected to the blade module 2 using a fastener 6. The locking wedge 5-3 is made of a material with good plasticity, preferably copper. This serves at least two purposes. First, because the tool is subject to significant cutting reaction forces during normal machining, the connection between the machine tool blade 1 and the blade module 2 requires an interference fit. Therefore, a readily machineable and easily replaceable component is required at the contact point, where the blade module 2 experiences the greatest force (generally, where the shear force is greatest), to prevent impact damage to the more expensive machine tool blade 1 and blade module 2. Second, the locking wedge 5-3 is made of a material with excellent plasticity. By deforming plastically under load, it provides a certain degree of shock absorption, protecting the cutter body when machining hard materials. During installation, the locking wedge 5-3 is the final pre-tightening component between the machine tool blade 1 and the blade body module 2. Its wedge shape adjusts the degree of interference fit between the two.

[0056] The locking key 5-2 is set in the locking key slot which is closed when the blade body module 2 and the machine tool blade 1 are engaged. It is only used to achieve an interference fit between the machine tool blade 1 and the blade body module 2, but does not have the function of adjusting the degree of interference fit. Figure 1 Preferably, the locking key 5-2 is arranged in a locking key groove formed at the vertical or inclined contact plane after the main groove stop and the main boss stop are closed.

[0057] In this specific embodiment, the main boss stop section of the blade body module 2 is configured with multiple folds. A gap is left on the horizontal lower plane for arranging the positioning gasket 5-1, a gap is left on the vertical and inclined vertical surface for arranging the locking block 5-2, and a gap is set at the top part that contacts the machine tool blade 1 and is subject to the greatest shear force for arranging the locking wedge 5-3. In this embodiment, through stress calculation, it is preferred that the first end face 1-1 of the blade body module 2 is an inclined surface with an angle of 105 with the horizontal line. 0 The adjacent second end face 1-2 is a horizontal plane; a locking wedge 5-3 is arranged at the angle between the two end faces; the locking wedge 5-3 is made of copper, and the cross section is set to a right-angled trapezoid. The size of the third end face 1-3 that matches the second end face 1-2 is set to an interference of 0.1 to 0.3 mm, and the angle between the third end face 1-3 and the second end face 1-2 is set to 106 0 ~107 0 The angle between the third end face 1-3 and the fourth end face 1-4 is 270 0 , and the angles between them and the horizontal line are 45 0 and 135 0 The locking key 5-2 is set at the angle between the two. The dimensions of all locking keys 5-2 in both directions are set to have an interference of 0.05 to 0.1 mm. The dimensions of all positioning gaskets 5-1 working surfaces are set to have an interference of 0.05 to 0.1 mm.

[0058] The direct and secure connection between the blade body module 2 and the machine tool blade 1 is crucial for machining quality. The two are securely connected via fasteners 6. In practical applications, this secure connection also leverages the locking and adjustment module 5: the positioning gasket 5-1, locking key 5-2, and locking wedge 5-3 all contribute to the interference fit between the blade body module 2 and the machine tool blade 1. The locking and adjustment module 5 thus serves both to accurately position the blade body module 2 for installation on the machine tool blade 1 and to securely connect the blade body module 2 to the machine tool blade 1, ensuring production quality.

[0059] Example 2

[0060] The existing rotor slot processing tool can only cut on one side during slot expansion processing, and the overall processing efficiency is low. In this embodiment, two tool rods are set on the transition block module, such as Figures 2-4 As shown, through the transition block module, the tool bars on both sides can be cut and expanded at the same time, greatly improving the processing efficiency. Specifically, the tool bar groove is provided with one or two. Preferably, a card slot is provided on the tool bar groove for snapping the tool bar and the distance block group 7. The transition block module is a vertical handle transition module 3-1 or a horizontal handle transition module 3-2. When using a vertical handle tool bar 4-1, a vertical handle transition module 3-1 is used, and one vertical handle tool bar 4-1 is respectively nested in the tool bar grooves provided on two opposite sides of the vertical handle transition module 3-1, and a distance block group 7 is provided at the rear ends of the two vertical handle tool bars 4-1; when using a horizontal handle tool bar 4-2, a horizontal handle transition module 3-2 is used, and two horizontal handle tool bars 4-2 are provided in a tool bar groove provided on the opposite sides of the secondary boss stop, and a distance block group 7 is provided between the two horizontal handle tool bars 4-2.

[0061] The horizontal-handle tool bar 4-2 has a relatively high upper limit on the width it can process. When a larger diameter rotor slot is required, the horizontal-handle tool bar 4-2 is used in conjunction with the vertical-handle tool bar 4-1. When expanding a slot with a smaller diameter, the vertical-handle tool bar 4-1 is used. After expanding to a certain diameter, the horizontal-handle tool bar can be replaced to expand the slot to a larger diameter. In this embodiment, the extension of either the horizontal-handle tool bar 4-2 or the vertical-handle tool bar 4-1 can be adjusted by adjusting the fastening position of the fastener 6 above the tool bar slot.

[0062] Adjusting the position of the tool bar is crucial to the accuracy of slotting. Therefore, the present invention has designed a distance block group 7. When a horizontal handle tool bar is used, the distance block group 7 is arranged in the middle of the two tool bars. Firstly, it positions the two tool bars, that is, the two blades 8, and secondly, it offsets part of the cutting reaction force from the two blades in opposite directions to maintain the stability of the tool body. On a vertical handle tool bar, a positioning block group 7 can also be set at the rear end of the blade 8 to press against the blade 8, thereby positioning the blade 8 and offsetting part of the cutting reaction force.

[0063] The distance block group 7 controls the elongation of the cutter bar and has a distance effect. In addition, the distance block group 7 can also offset the cutting reaction force transmitted from the cutter bar direction.

[0064] The blade 8 is clamped by the fastening holes in the tool bar and the preload applied by the fastener 6. During machining, the tip of the blade 8 is subject to XYZ forces. The two forces perpendicular to the tool bar can be partially offset by the transition block module structure, while the forces in the same direction as the tool bar can only be offset by the screw clamping, which will cause excessive screw stress. In addition, for horizontal handle tool bars, the distance block assembly 7 can achieve contact between the two tool bar ends, offsetting the forces acting in the direction of the tool bar.

[0065] This embodiment illustrates the installation of different blade body modules 2 on the same machine tool blade 1. Regardless of the type of slotting operation, whether slotting, straight slot expansion, or T-slot expansion, or whether a single or dual tool bar 4 is used, or whether a horizontal or vertical tool bar 4-2 or 4-1 is used, the modular fixture for rotor slot machining tools of the present invention simplifies tool changes, saves manpower and material resources, significantly reduces time, and improves machining efficiency.

[0066] Example 3

[0067] As attached Figure 6 As shown, tool bar slots are provided on the remaining side elevations of the secondary boss stop of the transition block module. Each tool bar slot is a through slot, facilitating the insertion of a tool bar. The tool bar slots on the opposite sides of the secondary boss stop are used to accommodate horizontal tool bars; the tool bar slots on the two adjacent sides of the secondary boss stop on the elevation are used to accommodate two vertical tool bars. This allows a single transition block module to be used for rotor slot expansion processing across a wider range of sizes, creating a composite transition block module-4.

[0069] S1: Select a tool arbor according to the blade 8 to be clamped; select a suitable transition block module according to the tool arbor; select a matching blade body module 2 according to the transition block module; select a locking adjustment module 5 and a fastener 6 suitable for clamping according to the blade body module 2 and the machine tool blade 1 to be used;

[0071] S3: Push the blade body module 2 further into the machine tool blade 1 so that the main groove stop and the main boss stop are in close contact. At this time, the locking keyway is closed; select a suitable fastener 6 to fasten the blade body module 2 pushed into the machine tool blade 1;

[0077] S7-2: When the horizontal handle transition module 3-2 is selected, the horizontal handle tool bar 4-2 is inserted into the tool bar groove of the horizontal handle transition module 3-2 and fastened with the fastener 6;

[0080] S9: According to the type of the selected transition block module, select an appropriate distance block group 7 and adjust the position, and use fasteners 6 to fasten the distance block group 7 to the transition block module.
