[0002] A multi-wire cutting machine is a device used for cutting hard materials. Its principle is to use the high-speed reciprocating motion of metal wires to bring abrasive particles into the processing area of ​​the material to be cut, thus grinding and cutting the material simultaneously into hundreds or thousands of thin slices. During the cutting process, a lifting mechanism moves the material up and down, enabling the metal wires to cut the material.

[0003] The existing lifting body is a large part that requires machining on its six sides, including two oppositely arranged worktable mounting surfaces and a ball screw mounting surface, wherein the worktable mounting surface has at least two positioning holes.

[0004] When machining the lifting body, two sets of fixing fixtures are needed to fix the lifting body on the rotary table of the boring and milling machine. One set of four-sided fixtures is used to machine the four sides except for the worktable mounting surface and the ball screw mounting surface when fixing the lifting body. The other set of double-sided fixtures is used to machine the worktable mounting surface and the ball screw mounting surface when fixing the lifting body.

[0005] Currently, the four-sided fixing clamps for lifting bodies are usually simple parts, such as a base for placing the lifting body, with bolts threaded on both sides of the base for clamping the lifting body. Multiple bolts are used to tighten the lifting body at designated positions on both sides. However, when fixing the lifting body to the base, it is necessary to clamp and align it repeatedly, and the fixing effect is not good. Utility Model Content

[0006] The purpose of this application is to provide a fixing fixture for machining the lifting body on all four sides of a multi-wire cutting machine, so as to solve the technical problem in the prior art that when fixing the lifting body to the base, multiple clamping and repeated alignment are required, and the fixing effect is not good.

[0007] To achieve the above objectives, the technical solution adopted in this application is: to provide a fixing fixture for machining the lifting body on all four sides of a multi-wire cutting machine, including a base for placing the lifting body and fitting it against the mounting surface of its worktable; the fixing fixture further includes: Multiple positioning components are disposed on the base and correspond one-to-one with the positioning holes. These positioning components are inserted into the positioning holes to fix the lifting body in the x and y axes. A fixing mechanism is provided on the base to press the lifting body down and fix it on the base, thereby fixing the lifting body in the z-axis direction.

[0008] In one possible implementation, based on the above technical solutions, the positioning element includes: Two side plates are fixed to both sides of the base; and Two positioning posts correspond one-to-one with the two side plates. The positioning posts are vertically fixed to the top surface of the side plates and are used to be inserted into the corresponding positioning holes.

[0009] In one possible implementation, based on the above technical solutions, the fixing mechanism includes: A first end fixing assembly is disposed on one side of the base for pressing down and fixing one end of the lifting body; and The second end fixing component is located on the other side of the base and is used to press down and fix the other end of the lifting body.

[0010] In conjunction with the above technical solutions, in one possible implementation, the first end fixing component includes: Two uprights are vertically mounted on the base, and one end of the lifting body is located between the two uprights and is higher than the uprights; A pressure strip is horizontally positioned above the two uprights; and Two clamping bolts correspond one-to-one with the two uprights, and the clamping bolts are threaded onto the uprights after passing through the pressure strip.

[0011] In one possible implementation, based on the above technical solutions, the bottom of the upright is detachably connected to the base.

[0012] In one possible implementation of the above technical solution, the second end fixing component includes: A mounting bracket is provided on the base, and one end of the lifting body is located inside the mounting bracket; Two adjusting bolts are vertically arranged on both sides of the mounting bracket, and the adjusting bolts pass through the mounting bracket and are threaded to the base; and One or more clamping rods are vertically fixed inside the mounting frame, and the bottom end of the clamping rod is used to press down on the end of the lifting body.

[0013] In one possible implementation, based on the above technical solutions, observation slots are provided at the bottom of both sides of the mounting bracket, and part of the outer peripheral surface of the adjusting bolt is exposed in the observation slots.

[0014] In one possible implementation, based on the above technical solutions, the lifting body has a ball screw hole perpendicular to the worktable mounting surface; the fixing mechanism further includes: The screw is vertically fixed on the base and is used to insert into the ball screw hole; A pressure plate, passing through the screw and located above the lifting body; and A clamping nut, threaded onto the screw and located above the pressure plate, is used to press the pressure plate downwards onto the lifting body.

[0015] In one possible implementation, based on the above technical solutions, the screw and the base are detachably connected.

[0016] In one possible implementation, based on the above technical solutions, the upper surface of the base is provided with several disassembly and assembly threaded grooves, and the bottom of the screw is threadedly connected to the disassembly and assembly threaded grooves; the fixing mechanism further includes: The nut is attached and threaded onto the screw and pressed against the upper surface of the base.

[0017] The advantages of the fixing fixture for four-sided machining of a lifting body of a multi-wire cutting machine provided in this application are as follows: Compared with the prior art, when fixing the lifting body, the worktable mounting surface of the lifting body is placed face down on the base, and the positioning component is inserted into the corresponding positioning hole.

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] refer to Figure 1 The existing lifting body 1 is a large part with six machining surfaces, including two oppositely arranged worktable mounting surfaces 11 and ball screw mounting surfaces 12. When the fixing fixture in this application fixes the lifting body 1, it is used to machine the four machining surfaces other than the worktable mounting surfaces 11 and ball screw mounting surfaces 12.

[0023] The present application provides a description of a fixing fixture for machining four sides of the lifting body of a multi-wire cutting machine.

[0024] like Figures 2 to 3 As shown, one embodiment of this application provides a fixing fixture for four-sided processing of a lifting body of a multi-wire cutting machine, including a base 2 for placing the lifting body 1; the worktable mounting surface 11 of the lifting body 1 faces downward and is attached to the upper surface of the base 2, and at least one positioning hole 13 is provided on each side of the worktable mounting surface 11 of the lifting body 1.

[0025] The fixing fixture also includes multiple positioning elements 3 and a set of fixing mechanisms 4; the multiple positioning elements 3 are set on the base 2 and correspond one-to-one with the positioning holes 13. The positioning elements 3 are used to insert into the positioning holes 13 to fix the lifting body 1 in the xy axis direction; the fixing mechanism 4 is set on the base 2 and is used to press the lifting body 1 down and fix it on the base 2 to fix the lifting body 1 in the z axis direction.

[0026] Specifically, in this embodiment, the base 2 is directly fixed to the rotary table of the boring and milling machine by bolts, so that the coordinate system of the fixing fixture is the same after each installation. Thus, after the lifting body 1 is fixed on the base 2, the coordinate system of the lifting body 1 can be the same each time it is installed, without the need to repeatedly establish the machining coordinate system, saving time and effort.

[0027] This embodiment provides a fixing fixture for four-sided processing of a lifting body of a multi-wire cutting machine. Compared with the prior art, when fixing the lifting body 1, the worktable mounting surface 11 of the lifting body 1 is placed downwards on the base 2, and the positioning member 3 is inserted into the corresponding positioning hole 13. The positioning member 3 restricts the horizontal direction of the lifting body 1, and the fixing mechanism 4 presses the lifting body 1 tightly onto the base 2 to restrict the vertical direction of the lifting body 1. Through the cooperation of the positioning member 3 and the fixing mechanism 4, the lifting body 1 and the base 2 can be more firmly fixed, improving the fixing effect of the lifting body 1. Moreover, it eliminates the need for repeated alignment of the specified positions on both sides of the lifting body 1 with multiple bolts as in the prior art, thus improving the fixing efficiency of the lifting body 1.

[0028] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning component 3 includes two side plates 31 and two positioning posts 32; the two side plates 31 are fixed on both sides of the base 2; the two positioning posts 32 correspond one-to-one with the two side plates 31, and the positioning posts 32 are vertically fixed on the top surface of the side plates 31 and are used to be inserted into the corresponding positioning holes 13.

[0029] When the lifting body 1 is in the first posture, the positioning holes 13 on both sides of its bottom surface cooperate with the positioning pins 32 in the positioning component 3. The positioning pins 32 are inserted into the corresponding positioning holes 13, which can accurately position and fix the lifting body 1 in the xy axis direction, effectively preventing the lifting body 1 from displacing in the xy axis direction during the processing, and improving the processing accuracy and stability of the lifting body 1 in the first posture; at the same time, it is simple and easy to operate, which improves the fixing efficiency of the lifting body 1.

[0030] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The fixing mechanism 4 includes a first end fixing component 41 and a second end fixing component 42; the first end fixing component 41 is disposed on one side of the base 2 and is used to press down and fix one end of the lifting body 1; the second end fixing component 42 is disposed on the other side of the base 2 and is used to press down and fix the other end of the lifting body 1.

[0031] The first end fixing component 41 and the second end fixing component 42 can press down and fix the lifting body 1 from both ends respectively, providing a more stable fixing effect on the lifting body 1 in the z-axis direction. In addition, the design of setting fixing components at both ends can be flexibly adjusted according to different sizes and shapes of the lifting body 1, enhancing the applicability and versatility of the first clamp.

[0032] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The first end fixing assembly 41 includes two uprights 411, a pressure strip 412, and two clamping bolts 413. The two uprights 411 are vertically arranged on the base 2, and one end of the lifting body 1 is located between the two uprights 411 and is higher than the uprights 411. The pressure strip 412 is horizontally arranged above the two uprights 411. The two clamping bolts 413 correspond one-to-one with the two uprights 411, and the clamping bolts 413 pass through the pressure strip 412 and are threaded to the uprights 411.

[0033] After the lifting body 1 is placed on the base 2, one end of the lifting body 1 is located between the two uprights 411. The pressure strip 412 is placed on the lifting body 1, and the clamping bolt 413 is passed through the pressure strip 412 and tightened to the uprights 411. This allows the pressure strip 412 to press the end of the lifting body 1 downwards onto the base 2. The structure is simple and reasonable, and easy to operate. Workers can easily adjust the tightening degree of the clamping bolt 413 according to actual needs to achieve the best fixing effect.

[0034] Moreover, the arrangement of the uprights 411 and the pressure strips 412 can evenly distribute the pressure, avoiding damage to the lifting body 1 caused by excessive local pressure, and ensuring the integrity and processing quality of the lifting body 1.

[0035] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom of the upright 411 is inverted T-shaped. The bottom of the upright 411 is detachably connected to the base 2 by two bolts. The bolts pass through the bottom of the upright 411 and are threaded to the base 2.

[0036] The inverted T-shaped structure can increase the contact area between the upright 411 and the base 2. When the bolt is passed through the bottom of the upright 411 and threaded to the base 2, the pressure can be effectively distributed, avoiding local pressure concentration that could damage the connection and ensuring the stability of the upright 411 installation.

[0037] When maintenance, replacement of parts, or structural adjustments are required for the fixing fixture, the upright 411 can be easily removed from the base 2 simply by loosening the bolts, saving a significant amount of time and labor costs.

[0038] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The second end fixing assembly 42 includes a mounting bracket 421, two adjusting bolts 422, and a clamping rod 423. The mounting bracket 421 is mounted on the base 2, and one end of the lifting body 1 is located inside the mounting bracket 421. The two adjusting bolts 422 are vertically arranged on both sides of the mounting bracket 421, and the adjusting bolts 422 pass through the mounting bracket 421 and are threaded to the base 2. There are one or more clamping rods 423, which are vertically fixed inside the mounting bracket 421, and the bottom end of the clamping rod 423 is used to press down on the end of the lifting body 1.

[0039] After the lifting body 1 is placed on the base 2, the mounting bracket 421 with the adjusting bolt 422 and the clamping rod 423 is placed on the base 2, and the end of the lifting body 1 is located inside the mounting bracket 421. At this time, the adjusting bolt 422 is rotated so that its bottom thread is screwed into the base 2, thereby realizing the height adjustment of the clamping rod 423 until the clamping rod 423 presses the end of the lifting body 1 downward and fixes it. The structure is simple and reasonable and easy to operate, and can provide reliable fixation of the lifting body 1 in the z-axis direction.

[0040] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom of both sides of the mounting bracket 421 is provided with observation slots 4211, and part of the outer peripheral surface of the adjusting bolt 422 is exposed in the observation slots 4211.

[0041] The observation slot 4211 exposes part of the outer peripheral surface of the adjusting bolt 422, allowing workers to directly observe the condition of the adjusting bolt 422 during operation, including the remaining thread length, tightness, and whether it is loose, which facilitates its maintenance.

[0042] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The lifting body 1 has a ball screw hole 14 perpendicular to the worktable mounting surface 11, and the ball screw hole 14 is perpendicular to both the worktable mounting surface 11 and the ball screw mounting surface 12.

[0043] The fixing mechanism 4 also includes a screw 43, a pressure plate 44, and a clamping nut 45; the screw 43 is vertically fixed on the base 2 and is used to insert into the ball screw hole 14; the pressure plate 44 passes through the screw 43 and is located above the lifting body 1; the clamping nut 45 is threadedly connected to the screw 43 and is located above the pressure plate 44, and the clamping nut 45 is used to press the pressure plate 44 downward onto the lifting body 1.

[0044] Using the ball screw hole 14 on the lifting body 1, the screw 43 initially limits the horizontal movement of the lifting body 1. The pressure plate 44 is inserted into the screw 43 and positioned above the lifting body 1. By tightening the clamping nut 45, the pressure plate 44 can be pressed downward onto the lifting body 1, thereby providing a more stable fixation of the lifting body 1 in the z-axis direction.

[0045] Moreover, the combination of screw 43, pressure plate 44 and clamping nut 45 is simple and reliable, easy to operate and adjust, and can adapt to the processing needs of lifting bodies 1 of different specifications and shapes, thus improving the versatility and applicability of the fixing fixture.

[0046] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The screw 43 is detachably connected to the base 2.

[0047] The detachable connection allows the screw 43 to be flexibly adjusted when facing lifting bodies 1 of different specifications and shapes. Since different lifting bodies 1 may have different positions and sizes of ball screw holes 14, when it is necessary to fix different lifting bodies 1, a suitable screw 43 can be selected according to the actual situation and installed on the base 2.

[0048] like Figure 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The upper surface of the base 2 is provided with several disassembly and assembly threaded grooves 21, and the bottom of the screw 43 is threaded into the disassembly and assembly threaded grooves 21; the fixing mechanism 4 also includes a disassembly and assembly nut 46, which is threaded into the screw 43 and pressed against the upper surface of the base 2.

[0049] The disassembly and assembly threaded groove 21 provides accurate positioning for the installation of the screw 43. The bottom of the screw 43 can be directly threaded into the disassembly and assembly threaded groove 21, which has high precision and stability. It can ensure that the screw 43 is installed perpendicular to the base 2, thereby ensuring that the screw 43 can be accurately inserted into the ball screw hole 14 of the lifting body 1, and achieving precise fixation of the lifting body 1.

[0050] Meanwhile, the installation of the disassembly nut 46 further enhances the firmness of the connection. After the screw 43 is installed in the disassembly threaded groove 21, the disassembly nut 46 is threaded onto the screw 43 and pressed against the upper surface of the base 2. This effectively prevents the screw 43 from loosening during use, making the connection between the screw 43 and the base 2 more reliable. When processing the lifting body 1, it can withstand greater external forces, ensuring the stability and reliability of the fixing fixture.

[0051] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
