Description

Technical Field

[0001] The present invention relates to the technical field of shearing equipment, and particularly relates to a shearing equipment for processing metal materials of current sensors. Background Art

[0002] In the field of modern electronic device manufacturing, as a key component, the performance of current sensors directly affects the operation stability and accuracy of the entire device. And the processing quality of the metal materials of current sensors plays a decisive role in the performance of the sensors. During the processing of metal materials for current sensors, shearing is a crucial process, which is directly related to the dimensional accuracy and surface quality of the metal materials.

[0003] In order to ensure the stability of installation and fixation, the cutting knives on existing shearing equipment are mostly locked and fixed by multiple bolts together. This causes that when disassembling and assembling them, it is necessary to sequentially rotate and loosen multiple bolts in a step-by-step manner in both positive and negative directions, and the operation is rather cumbersome. As a result, the cutting knives cannot take into account the convenience and efficiency of disassembly and assembly on the premise of ensuring the installation stability, and the use effect is not good. Summary of the Invention

[0004] In view of this, the present invention provides a shearing equipment for processing metal materials of current sensors to solve the problem that the cutting knives cannot take into account the convenience and efficiency of disassembly and assembly on the premise of ensuring the installation stability.

[0005] The technical solution proposed by the present invention is: a shearing equipment for processing metal materials of current sensors, which specifically includes a rectangular installation frame and a cutting knife. The cutting knife is fixedly abutted against the outer side of the first long side wall of the rectangular installation frame.

[0006] On the inner side of the cutting knife, four L-shaped tension rods are symmetrically welded in pairs. The four L-shaped tension rods penetrate through the first long side wall of the rectangular installation frame and are inserted into the rectangular installation frame. A vertically sliding tightening frame is installed inside the rectangular installation frame. The tightening frame is jointly composed of two horizontally arranged mounting plates and a horizontally arranged sliding rod welded to the bottoms of the two horizontally arranged mounting plates. Two horizontally sliding tightening plates are symmetrically installed on the horizontally arranged mounting plates. A T-shaped sliding rod that is pushed and reset by a spring is slidably installed through the middle part of the horizontally arranged mounting plate. Two second connecting rods are symmetrically rotatably connected between the first end of the T-shaped sliding rod and the two tightening plates. A threaded propulsion shaft is rotatably installed through the position inside the rectangular installation frame far from the cutting knife. Three threaded rings are screwed and sleeved on the threaded propulsion shaft at equal intervals. Three first connecting rods are rotatably connected between the three threaded rings and the horizontally arranged sliding rod.

[0007] Further, when the tightening frame faces the threaded propulsion shaft, the tail end of the T-shaped sliding rod is separated from the first long side wall. At the same time, the four tightening plates on the tightening frame extend out and abut against and tightly hold the horizontal rod segments of the four L-shaped tension rods.

[0008] When the top pressing frame slides away from the threaded propulsion shaft, the tail end of the T-shaped sliding rod abuts against the U-shaped mounting frame. At the same time, the four top pressing plates retract and withdraw from the space between the horizontal rod segments of the four L-shaped tension rods and the first long side wall.

[0009] Furthermore, two positioning sleeves are symmetrically welded at both ends of the horizontal mounting plate, and the two top pressing plates on the horizontal mounting plate are correspondingly and slidably fitted through the two positioning sleeves.

[0010] Furthermore, two vertical positioning rods are symmetrically welded at the inner bottom position of the first long side wall, and the two end portions of the horizontal sliding rod are correspondingly slidably fitted with the two vertical positioning rods.

[0011] Furthermore, four rectangular grooves are symmetrically and penetratingly formed in the first long side wall in two groups of two, and the four L-shaped tension rods are correspondingly and penetratingly fitted with the four rectangular grooves.

[0012] Furthermore, it further includes a base. Two vertical support rods are symmetrically welded at the top end of the base. The top ends of the vertical support rods are jointly welded with a horizontal platform plate. A rectangular mounting frame is welded on one long side of the horizontal platform plate;

[0013] A row of L-shaped connecting plates are welded between the rectangular mounting frame and the horizontal platform plate. A cover plate is sealed on the top opening of the rectangular mounting frame, and the cover plate is flush with the horizontal platform plate.

[0014] Furthermore, a vertical support rod is welded at a corner position of the base. A swing rod is rotatably installed at the top end of the vertical support rod. A rectangular mounting frame is also welded at the head end of the swing rod, and this rectangular mounting frame is arranged in a flipped and inverted manner.

[0015] Furthermore, a power assembly is fixedly installed in the middle section of the vertical support rod, and a driving wheel is sleeved at the head end of the power assembly rotating shaft.

[0016] Furthermore, a rod sleeve is slidably installed on the part of the vertical support rod above the power assembly. A pull rod is rotatably connected between the rod sleeve and the outer periphery of the driving wheel, and a connecting rod is rotatably connected between the rod sleeve and the tail end of the swing rod.

[0017] A shearing device for processing metal materials of a current sensor provided by the present invention has the following beneficial effects:

[0018] 1. When the four top pressing plates abut against and press the horizontal rod segments of the four L-shaped tension rods, the top thrust of the top pressing frame can be evenly distributed on the cutting tool to stably and effectively position the cutting tool; when the top pressing frame slides away from the threaded propulsion shaft, the four top pressing plates retract and withdraw from the space between the horizontal rod segments of the four L-shaped tension rods and the first long side wall, releasing the cutting tool. The four top pressing plates withdraw from the above space to create a vacant position, which can prevent the four top pressing plates from protruding from the above space and blocking or interfering with the pulling and disassembling action of the cutting tool driving the L-shaped tension rod, facilitating the disassembly of the cutting tool.

[0019] 2. The three threaded rings, the three first connecting rods and the tightening frame are jointly connected to form three crank-slider mechanisms. Through these three mechanisms, by simply rotating the threaded propulsion shaft forward and backward, the three threaded rings can be driven to slide reciprocally along the threaded propulsion shaft synchronously, controlling the tightening frame to slide towards or away from the threaded propulsion shaft, so that the four tightening plates contact or separate from the horizontal rod segments of the four L-shaped tension rods, completing the tightening and loosening of the cutter at one time. Compared with the prior art in which the cutter is set to be locked and fixed by multiple bolts, this can save the cumbersome steps of sequentially rotating the multiple bolts forward and backward to tighten and loosen them when disassembling and assembling the cutter, enabling the cutter to take into account the convenience and efficiency of disassembly and assembly operations while ensuring the installation stability.

[0020] 3. Through the crank-slider mechanism composed of the T-shaped slide bar, the second connecting rod and the tightening plate, the four tightening plates can slide telescopically by using the driving force when the tightening frame slides to tighten and loosen the cutter. This can save the trouble of manually performing telescopic switching on the four tightening plates additionally when disassembling and assembling the cutter, which helps to ensure the convenient and efficient disassembly of the cutter.

[0041] Please refer to Figures 1 to 9 ;

[0042] Embodiment 1:

[0043] The present invention provides a shearing device for processing metal materials of a current sensor, including a rectangular mounting frame 2 and a cutter 4, and a cutter 4 is fixedly abutted against the outside of the first long side wall 203 of the rectangular mounting frame 2;

[0044] On the inner side of the cutting knife 4, there are four L-shaped tension rods 401 symmetrically welded in pairs. The four L-shaped tension rods 401 penetrate through the first long side wall 203 of the rectangular installation frame 2 and are inserted into the rectangular installation frame 2. Inside the rectangular installation frame 2, there is a vertically sliding tightening frame 5 installed. The tightening frame 5 is composed of two horizontally arranged mounting plates 501 and a horizontally arranged sliding rod 502 welded to the bottoms of the two horizontally arranged mounting plates 501. On the horizontally arranged mounting plates 501, two horizontally sliding tightening plates 504 are symmetrically installed. In the middle part of the horizontally arranged mounting plates 501, there is a T-shaped sliding rod 503 installed through sliding and reset by a spring. Between the first end of the T-shaped sliding rod 503 and the two tightening plates 504, there are two second connecting rods 5031 symmetrically rotatably connected. Inside the rectangular installation frame 2, at a position far from the cutting knife 4, there is a threaded propulsion shaft 202 installed through rotation. On the threaded propulsion shaft 202, three threaded rings 2021 are screwed and sleeved at equal intervals. Between the three threaded rings 2021 and the horizontally arranged sliding rod 502, there are three first connecting rods 5021 rotatably connected.

[0045] Preferably, at both ends of the horizontally arranged mounting plate 501, there are two positioning sleeves 5011 symmetrically welded. The two tightening plates 504 on the horizontally arranged mounting plate 501 are correspondingly in sliding fit with the two positioning sleeves 5011 through penetration.

[0046] Preferably, at the inner bottom position of the first long side wall 203, there are two vertically arranged positioning rods 205 symmetrically welded. The two end portions of the horizontally arranged sliding rod 502 are correspondingly in sliding fit with the two vertically arranged positioning rods 205.

[0047] Preferably, on the first long side wall 203, there are four rectangular grooves 204 symmetrically opened in pairs through penetration. The four L-shaped tension rods 401 are correspondingly in penetration fit with the four rectangular grooves 204.

[0048] On the basis of Embodiment 1, Embodiment 2:

[0049] A shearing device for processing a metal material of a current sensor further includes a base 3. At the top end of the base 3, there are two erected support rods 303 symmetrically welded. At the top ends of the erected support rods 303, there is a horizontal platform plate 1 jointly welded. On one long side of the horizontal platform plate 1, there is a rectangular installation frame 2 welded. Between the rectangular installation frame 2 and the horizontal platform plate 1, there is a row of L-shaped connecting plates 101 welded. On the top opening of the rectangular installation frame 2, there is a cover plate 201 sealed. The cover plate 201 is flush with the horizontal platform plate 1.

[0050] Preferably, at a corner position of the base 3, there is a vertical support rod 301 welded. At the top end of the vertical support rod 301, there is a swing rod 304 rotatably installed. At the first end of the swing rod 304, there is also a rectangular installation frame 2 welded, and this rectangular installation frame 2 is arranged in a flipped and inverted manner.

[0051] Preferably, in the middle section of the vertical support rod 301, there is a power assembly 6 fixedly installed. At the first end of the rotating shaft of the power assembly 6, there is a driving wheel 601 sleeved.

[0052] Preferably, a rod sleeve 302 is slidably mounted on the portion of the vertical support rod 301 located above the power assembly 6, a pull rod 602 is rotatably connected between the rod sleeve 302 and the outer periphery of the driving wheel 601, and a connecting rod 305 is rotatably connected between the rod sleeve 302 and the tail end of the rocker arm 304.

[0053] The specific details, implementation steps, functions and interrelationships of the above contents, and their roles in implementing the present invention are described and explained in detail below:

[0054] When the jacking frame 5 is directed toward the threaded advancement shaft 202, the four jacking plates 504 on the jacking frame 5 extend from the four positioning sleeves 5011 and press against the four transverse rod sections of the L-shaped tensioning rod 401 to fix the jacking on the first long side wall 203. When the four jacking plates 504 press against the four transverse rod sections of the L-shaped tensioning rod 401, the jacking force of the jacking frame 5 can be evenly distributed on the cutter 4 to implement stable and effective positioning of the cutter 4; when the jacking frame 5 slides away from the threaded advancement shaft 202, the four jacking plates 504 are retracted and released from the space between the four transverse rod sections of the L-shaped tensioning rod 401 and the first long side wall 203, and the four jacking plates 504 are pulled out of the empty space above, which can prevent the four jacking plates 504 from protruding from the above space, thereby blocking the cutter 4 from driving the L-shaped tensioning rod 401 to be pulled out. The disassembly action makes it convenient to disassemble the cutter 4; the three threaded rings 2021, the three first connecting rods 5021 and the tightening frame 5 are connected together to form a three-crank slider mechanism, through which the three threaded rings 2021 can be driven to slide back and forth along the threaded advancement shaft 202 synchronously by simply rotating the threaded advancement shaft 202 forwards and backwards, and the tightening frame 5 can be controlled to slide toward or away from the threaded advancement shaft 202, so that the four tightening plates 504 are in contact with or separated from the four L-shaped tensioning rods 401 horizontal rod sections, and the cutter 4 can be tightened and loosened at one time. Compared with the existing technology in which the cutter 4 is set to be locked and fixed with multiple bolts, the cumbersome steps of tightening and loosening multiple bolts in turn forward and backward when disassembling and assembling the cutter 4 can be eliminated, so that the cutter 4 can ensure the installation stability while taking into account the convenience and efficiency of the disassembly and assembly operation.

[0055] The T-shaped slide bar 503, two second connecting rods 5031 and two pressing plates 504 are jointly connected to form two crank-slider mechanisms. Through these two crank-slider mechanisms, sliding the T-shaped slide bar 503 towards or away from the threaded propulsion shaft 202 can drive the two pressing plates 504 to slide telescopically towards each other along the two positioning sleeves 5011. When the pressing frame 5 is driven to slide towards the threaded propulsion shaft 202, the two T-shaped slide bars 503 on it are separated from the first long side wall 203. At this time, the two T-shaped slide bars 503 can use the rebound pushing effect of the springs on them (when the T-shaped slide bars 503 are in contact with the first long side wall 203, the springs on them are in a compressed state) to slide towards the threaded propulsion shaft 202 and push the four pressing plates 504 out of the four positioning sleeves 5011. When the pressing frame 5 is driven to slide away from the threaded propulsion shaft 202, the ends of the two T-shaped slide bars 503 are in contact with the first long side wall 203, which can push and drive the four pressing plates 504 to retract into the four positioning sleeves 5011. Furthermore, through the crank-slider mechanism composed of the T-shaped slide bar 503, the second connecting rod 5031 and the pressing plate 504, the four pressing plates 504 can telescopically slide by using the driving force when the pressing frame 5 slides the cutter 4 to loosen or tighten. This can save the trouble of manually performing telescopic switching on the four pressing plates 504 additionally when disassembling and assembling the cutter 4, which helps to ensure the convenient and efficient disassembly of the cutter 4.

[0056] Working principle: During use, place the metal material to be processed for manufacturing the current sensor housing on the top of the horizontal table board 1;

[0057] The driving wheel 601, the pull rod 602 and the rod sleeve 302 are jointly connected to form a crank-slider mechanism. Through this mechanism, when the power assembly 6 drives the driving wheel 601 to rotate, it can drive the rod sleeve 302 to slide up and down. The rod sleeve 302 is also jointly connected with the swing rod 304 and the connecting rod 305 to form a crank-rocker mechanism. Through this mechanism, when the rod sleeve 302 is driven to slide up and down, it can drive the swing rod 304 and the rectangular mounting frame 2 and the cutter 4 fixed on the swing rod 304 to swing up and down to perform shearing processing on the metal material;

[0058] Note: During the shearing process, it is necessary to press and fix the metal material on the top of the horizontal table board 1 by hand to prevent the tail end of the metal material from warping up during shearing, which may affect the normal implementation of the shearing operation;

[0059] When the pressing frame 5 faces the threaded propulsion shaft 202, the four pressing plates 504 on the pressing frame 5 extend from the four positioning sleeves 5011 and abut and press against the horizontal rod segments of the four L-shaped tension rods 401, and are pressed and fixed on the first long side wall 203; when the pressing frame 5 slides away from the threaded propulsion shaft 202, the four pressing plates 504 retract and release the cutter 4 from the space between the horizontal rod segments of the four L-shaped tension rods 401 and the first long side wall 203;

[0060] Three threaded rings 2021, three first connecting rods 5021 and a tightening frame 5 are jointly connected to form three crank-slider mechanisms. Through these three mechanisms, by the simple operation of rotating the threaded propulsion shaft 202 forward and backward, the three threaded rings 2021 can be driven to reciprocally slide along the threaded propulsion shaft 202 synchronously, controlling the tightening frame 5 to slide towards or away from the threaded propulsion shaft 202, so that the four tightening plates 504 contact or separate from the horizontal rod segments of the four L-shaped tension rods 401, thereby completing the tightening and loosening of the cutting tool 4.

[0061] A T-shaped slide bar 503, two second connecting rods 5031 and two tightening plates 504 are jointly connected to form two crank-slider mechanisms. Through these two crank-slider mechanisms, by sliding the T-shaped slide bar 503 towards or away from the threaded propulsion shaft 202, the two tightening plates 504 can be driven to slide towards each other and expand and contract along the two positioning sleeves 5011; when the tightening frame 5 is driven to slide towards the threaded propulsion shaft 202, the two T-shaped slide bars 503 on it are separated from the first long side wall 203. At this time, the two T-shaped slide bars 503 can slide towards the threaded propulsion shaft 202 by using the rebound pushing effect of the springs on them (when the T-shaped slide bars 503 are in contact with the first long side wall 203, the springs on them are in a compressed state) and push the four tightening plates 504 out of the four positioning sleeves 5011. When the tightening frame 5 is driven to slide away from the threaded propulsion shaft 202, the ends of the two T-shaped slide bars 503 are in contact with the first long side wall 203, which can push and drive the four tightening plates 504 to retract into the four positioning sleeves 5011.
