Description

Technical Field

[0001] This utility model relates to the field of tool fixing technology, specifically a metalworking tool fixing device that is easy to disassemble and maintain. Background Technology

[0002] In the field of metal cutting, such as turning, milling, and drilling, the tool fixing device is one of the key components of the machine tool. Its performance and convenience directly affect the machining accuracy, efficiency, and ease of operation and maintenance.

[0003] However, traditional tool fixing devices typically use methods such as direct bolt fastening, taper sleeve clamping, or complex mechanical chucks to mount tools onto the machine tool spindle or tool post. While these fixing methods can provide the necessary clamping force, they often exhibit certain limitations in practical applications, especially when frequent tool changes are required to adapt to different machining requirements or when tool maintenance (such as sharpening or changing inserts) is needed.

[0004] To address this problem, a metalworking tool fixing device that is easy to disassemble and maintain is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a metalworking tool fixing device that is easy to disassemble and maintain, with the advantages of convenient assembly and disassembly and efficient maintenance, solving the problem that traditional tool fixing devices are cumbersome to disassemble and difficult to quickly adapt to processing needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metalworking tool fixing device that is easy to disassemble and maintain, including an adjustment mechanism, a clamping mechanism mounted on the adjustment mechanism, a tool body detachably mounted on the clamping mechanism, the clamping mechanism including a sliding frame, the sliding frame being slidably mounted on the adjustment mechanism, and a clamping frame mounted on the sliding frame, the clamping frame being used to clamp the tool body; The adjustment mechanism includes a mounting base, on which an adjustment screw is mounted. The adjustment screw is used to adjust the movement trajectory of the sliding frame on the mounting base.

[0007] Preferably, the sliding frame is provided with a second guide groove and a screw hole, and the adjusting screw is threadedly connected to the sliding frame through the screw hole.

[0008] In the design, the second guide groove on the sliding frame achieves a precise nesting fit with the first guide groove in the mounting base, and the screw hole has the function of threaded engagement with the adjusting screw. The slot-hole linkage structure ensures that the sliding frame has both guiding stability and linear driving force when it moves.

[0009] Preferably, the clamping frame passes through the sliding frame and is fitted with a fixing cover. The fixing cover is used to position the clamping frame on the sliding frame, and the fixing cover is detachably installed with the clamping frame by a positioning pin. The clamping frame has a clamping groove for positioning the tool body, and a buffer pad is provided inside the clamping groove.

[0010] In the design, the fixed cover is fitted outside the clamping frame to achieve axial limiting and fixing of the clamping frame. The positioning pin has a detachable connection function. The combination of the cover and the pin is used to lock the clamping frame, so as to achieve quick assembly and disassembly. Meanwhile, the clamping groove is equipped with a buffer pad that can absorb tool vibration and prevent damage, and the flexible contact surface design enhances the clamping protection of the tool body.

[0011] Preferably, the mounting base has a reserved mounting hole, which is used to install the mounting base with bolts; The mounting base is provided with a first guide groove, which works in conjunction with a second guide groove to guide the movement trajectory of the sliding frame. The mounting base has mounting covers fixed to both ends by mounting screws, and the mounting covers have holes for the adjustment screws to pass through.

[0012] In the design, the reserved mounting holes of the mounting base enable multi-interface installation with the machine tool through standard bolts; The nested cooperation of the first guide groove and the second guide groove has a bidirectional sliding guidance function. The mirror-symmetric guide groove structure ensures that the sliding frame's movement trajectory is free from deviation. The end caps provide sealing support and limit function, and the screw-fixed end cap design facilitates the installation and maintenance of the adjusting screw.

[0013] Preferably, the adjusting screw is rotatably connected to the mounting cover via a bearing, and one end of the adjusting screw passes through the mounting cover and is keyed to a handwheel; The adjusting screw is designed by welding two screws that are mirror-distributed.

[0014] In the design, the adjusting screw is rotatably connected to the mounting cover via a bearing to achieve low-friction rotary transmission. The key-connected handwheel has a manual precision adjustment function, and the external control wheel structure improves the ease of operation; The mirror-welded twin-screw structure has the advantages of high rigidity and segmented maintenance. It uses a split welding process to replace the integral screw, reducing processing costs and maintenance difficulty.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves efficient assembly, disassembly, and maintenance of the tool body by setting up independently operable clamping and adjustment mechanisms.

[0016] The sliding frame of the clamping mechanism directly supports the clamping frame. By separating the sliding connection structure between the sliding frame and the adjustment mechanism, the clamping frame can be disassembled independently.

[0017] The clamping design directly clamps the tool body, eliminating the need for the traditional step-by-step bolt removal process. When changing tools, only the clamping device needs to be released, significantly reducing operation time.

[0018] The linear drive of the adjusting screw to the sliding frame allows for tool displacement adjustment independent of the clamping function, eliminating the need to disassemble the transmission components for maintenance. The separate structural design allows for individual maintenance of the clamping mechanism, avoiding the need for complete disassembly of the adjusting mechanism and significantly reducing downtime.

[0019] The sliding mount feature of the sliding bracket on the adjustment mechanism, combined with the precise trajectory control of the adjusting screw, enables rapid tool position reset. After replacing the tool body, machining accuracy can be restored by fine-tuning the position of the sliding bracket using the adjusting screw, eliminating the need for recalibrating the entire machine.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of the present invention is provided: a metalworking tool fixing device that is easy to disassemble and maintain, including an adjustment mechanism 1, a clamping mechanism 2 installed on the adjustment mechanism 1, a tool body 3 detachably installed on the clamping mechanism 2, the clamping mechanism 2 including a sliding frame 21, the sliding frame 21 being slidably installed on the adjustment mechanism 1, and a clamping frame 23 installed on the sliding frame 21, the clamping frame 23 being used to clamp the tool body 3; The adjustment mechanism 1 includes a mounting base 11, on which an adjustment screw 14 is mounted. The adjustment screw 14 is used to adjust the movement trajectory of the sliding frame 21 on the mounting base 11.

[0024] Specifically, by setting up an independently operable clamping mechanism 2 and an adjusting mechanism 1, efficient assembly, disassembly, and maintenance of the tool body 3 are achieved.

[0025] The sliding frame 21 of the clamping mechanism 2 directly supports the clamping frame 23. By separating the sliding connection structure between the sliding frame 21 and the adjusting mechanism 1, the clamping frame 23 can be disassembled independently.

[0026] The clamping design of the clamping frame 23 directly clamps the tool body 3, eliminating the traditional step-by-step bolt disassembly process. When changing tools, it is only necessary to release the clamping frame 23, which significantly shortens the operation time.

[0027] The linear drive of the adjusting screw 14 to the sliding frame 21 allows for tool displacement adjustment independent of the clamping function, eliminating the need to disassemble the transmission components during maintenance. The separate structural design allows for individual maintenance of the clamping mechanism 2, avoiding the need for complete disassembly of the adjusting mechanism 1 and significantly reducing downtime.

[0028] The sliding mounting feature of the sliding bracket 21 on the adjustment mechanism 1, combined with the precise trajectory control of the adjusting screw 14, enables rapid tool position reset. After replacing the tool body 3, the machining accuracy can be restored by finely adjusting the position of the sliding bracket 21 through the adjusting screw 14, without the need for repeated calibration of the entire machine. Example 2

[0029] To achieve precise tool displacement adjustment, such as Figure 3 and Figure 4 As shown, in this embodiment, the sliding frame 21 is provided with a second guide groove 211 and a screw hole 212, and the adjusting screw 14 is threadedly connected to the sliding frame 21 through the screw hole 212.

[0030] Specifically, the second guide groove 211 on the sliding frame 21 achieves precise nesting with the first guide groove 112 in the mounting base 11, and the screw hole 212 has the function of thread engagement with the adjusting screw 14. The slot-hole linkage structure ensures that the sliding frame 21 has both guiding stability and linear driving force when it moves.

[0031] Furthermore, the clamping frame 23 passes through the sliding frame 21 and is fitted with a fixing cover 22. The fixing cover 22 is used to position the clamping frame 23 on the sliding frame 21. The fixing cover 22 is detachably installed with the clamping frame 23 by a positioning pin 221. The clamping frame 23 has a clamping groove 231, which is used to position the tool body 3. A buffer pad is provided inside the clamping groove 231.

[0032] Specifically, the fixing cover 22 is fitted onto the clamping frame 23 to achieve axial limiting and fixing of the clamping frame 23. The positioning pin 221 has a detachable connection function and adopts a combination of cover and pin locking method to achieve quick assembly and disassembly of the clamping frame 23. Meanwhile, the clamping groove 231 is equipped with a buffer pad that can absorb tool vibration and prevent damage. The flexible contact surface design enhances the clamping protection of the tool body 3. Example 3

[0033] To achieve stable guidance and convenient maintenance of the device, such as Figure 1 and Figure 2 As shown, in this embodiment, the mounting base 11 is provided with a reserved mounting hole 111, which is used to install the mounting base 11 with bolts; The mounting base 11 has a first guide groove 112, which works in conjunction with the second guide groove 211 to guide the movement trajectory of the sliding frame 21. Mounting covers 12 are fixed to both ends of the mounting base 11 by mounting screws. The mounting covers 12 have holes for the adjusting screw 14 to pass through.

[0034] Specifically, the reserved mounting holes 111 of the mounting base 11 enable multi-interface adaptation and installation with the machine tool via standard bolts; The nested cooperation between the first guide groove 112 and the second guide groove 211 provides bidirectional sliding guidance. The mirror-symmetric guide groove structure ensures that the sliding frame 21 moves without deviation. The end caps 12 have a sealing, supporting and limiting function. They adopt a screw-fixed end cap design, which facilitates the installation and maintenance of the adjusting screw 14.

[0035] Furthermore, the adjusting screw 14 is rotatably connected to the mounting cover 12 via a bearing, and one end of the adjusting screw 14 passes through the mounting cover 12 and is keyed to a handwheel 13; The adjusting screw 14 is designed by welding two screws that are mirror-distributed.

[0036] Specifically, the adjusting screw 14 is rotatably connected to the mounting cover 12 via a bearing to achieve low-friction rotary transmission; The key-connected handwheel 13 has a manual precision adjustment function, and the external control wheel structure improves the ease of operation; The mirror-welded twin-screw structure has the advantages of high rigidity and segmented maintenance. It uses a split welding process to replace the integral screw, reducing processing costs and maintenance difficulty.

[0037] When using this utility model, firstly, the mounting base 11 is fixed to the machine tool worktable through the reserved mounting holes 111 and bolts. Then, check the bearing connection status between the adjusting screw 14 and the mounting cover 12 to ensure that the handwheel 13 rotates smoothly.

[0038] The tool body 3 is embedded in the clamping groove 231 of the clamping frame 23, and the buffer pad is used to fit the tool surface.

[0039] Rotating the handwheel 13 drives the adjusting screw 14 to rotate. Since the adjusting screw 14 is threadedly engaged with the screw hole 212 of the sliding frame 21, the sliding frame 21 slides bidirectionally along the first guide groove 112 of the mounting base 11 and its own second guide groove 211, driving the tool body 3 to move precisely to the machining position.

[0040] After the machine tool is started, the tool body 3 performs cutting operations. During this process, the buffer pad in the clamping groove 231 absorbs vibration and reduces the risk of tool displacement.

[0041] After processing, first loosen the locating pin 221 to remove the fixing cover 22, then the clamping frame 23 can be pulled out. If maintenance and adjustment mechanism 1 is required, the screws on the mounting cover 12 can be removed, and the separately welded adjusting screw 14 can be taken out in sections to avoid replacing the whole unit. After cleaning or replacing the parts, reassemble them by reversing the steps.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
