Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting machine tools, in particular to a wire tightening adjusting mechanism of a wire cutting machine tool. BACKGROUND

[0002] The wire cutting machine tool is a precision electro-erosion machining equipment that uses molybdenum wire or tube wire as electrode wire, generates high temperature through pulse discharge between the electrode wire and the workpiece, and performs workpiece material melting and cutting along a preset trajectory in a continuous moving mode of fast or slow wire walking, which is widely used in mold manufacturing, medical devices, aerospace and other fields.

[0003] During use of the wire cutting machine tool, in order to prevent problems such as wire running disorder and sliding out of the guide wheel due to insufficient tension of the electrode wire, and to prevent the vibration amplitude from increasing during cutting due to insufficient tension of the electrode wire, affecting the machining precision, the tension of the electrode wire needs to be adjusted by a tensioning mechanism.

[0004] After searching the authorized patent No. CN109365935B, a wire tightening mechanism is disclosed, which includes a support panel, the upper end of the support panel is provided with an entry guide wheel for winding the molybdenum wire in, and an exit guide wheel is oppositely arranged at a preset distance from the entry guide wheel and is used for winding the molybdenum wire out; further comprising a tensioning guide wheel cooperatively arranged with the entry guide wheel and the exit guide wheel, used to generate tension for tensioning the molybdenum wire and preventing the molybdenum wire from being pulled off, and an elastic mechanism cooperatively connected with the side surface of the support panel, used to drive the tensioning guide wheel to extend and retract perpendicular to the side surface of the support panel.

However, relying on the elastic force of the spring component for wire tightening operation is prone to cause plastic deformation of the spring component due to fatigue, which affects the stability of the tensioning force in the wire tightening mechanism. In addition, the elastic coefficient of the spring component is fixed, which causes the tensioning guide wheel to be able to move only within a limited range, thereby limiting the adjustment range of the tensioning force.

In addition, the problems that the adjusting range of the electrode wire tightness is limited and the stability of the tightness after adjustment is insufficient are solved. Through the pushing and extruding action between the pushing block 10 and the adjusting frame 7, the pushing block 10 is driven by the electric telescopic rod 8, so that the adjusting frame 7 drives the tensioning groove wheel 2 to slide. Through the cooperation among the tensioning groove wheel 2, the wire feeding groove wheel 4 and the wire discharging groove wheel 5, the electrode wire is automatically tensioned. Through the sliding adjustment of the position of the tensioning groove wheel 2, the applicability of the electrode wire tightness is freely adjusted. In the sliding process of the tensioning groove wheel 2 driven by the adjusting frame 7, through the clamping action between the ratchet lock block 11 and the ratchet frame 13, the locking after the sliding adjustment of the tensioning groove wheel 2 is realized, so that the stability of the tightness of the electrode wire after being tensioned by the tensioning groove wheel 2 is ensured. In addition, in the process of tensioning the electrode wire, the tensioning groove wheel 2 is driven by the adjusting assembly 3, the monitoring assembly 6 is driven by the adjusting assembly 3, and the real-time monitoring and measurement of the tightness of the electrode wire in the process of adjusting the electrode wire tightness are realized by the monitoring assembly 6.

[0046] The technical scheme: please refer to Figures 1-10 A wire cutting machine tool tension adjusting mechanism, comprising a shell frame 1, a connecting plate part of integrated structure is vertically arranged at the right end of the rear shell wall in the shell frame 1, when the tension adjusting mechanism is arranged, the connecting plate part in the shell frame 1 is fixedly connected at a preset position of the wire cutting electrical discharge machine through bolts, and the front shell wall of the shell frame 1 is provided with a protective shell 101 for electrode wire insertion;

[0047] Further comprising a tensioning groove wheel 2 and a monitoring assembly 6, the tensioning groove wheel 2 constitutes a sliding adjusting structure in the protective shell 101 through driving of the adjusting assembly 3, and the adjusting assembly 3 is arranged in the right segment shell cavity of the shell frame 1 and is arranged in parallel with the shell frame 1, an inlet groove wheel 4 capable of rotating in the protective shell 101 is arranged above the tensioning groove wheel 2, and an outlet groove wheel 5 capable of rotating in the protective shell 101 is arranged below the tensioning groove wheel 2, the electrode wire is automatically and stably tensioned through cooperation among the tensioning groove wheel 2, the inlet groove wheel 4 and the outlet groove wheel 5, in addition, the electrode wire tensioning force is adaptively and freely adjusted through sliding adjustment of the tensioning groove wheel 2, and the monitoring assembly 6 is arranged in sliding state on the left segment shell wall of the shell frame 1 and is driven in linkage through the adjusting assembly 3, and the monitoring assembly 6 performs real-time monitoring and measurement of the tensioning force in the electrode wire tensioning adjustment.

[0048] Specifically, in the technical scheme, the electrode wire is automatically tensioned by the tensioning groove wheel 2, according to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the adjusting assembly 3 comprises an adjusting frame 7 and an electric telescopic rod 8, the adjusting assembly 3 drives the tensioning groove wheel 2 to perform linear sliding motion in horizontal state, since the electric telescopic rod 8 is arranged and fixedly installed on the right shell wall of the shell frame 1 through bolts and is arranged in parallel with the shell frame 1, wherein the output rod body penetrates from the right segment shell cavity of the shell frame 1 to the left segment shell cavity of the shell frame 1, since the pushing block 10 is arranged in square block structure and is movably clamped in the right segment shell cavity of the shell frame 1, the pushing block 10 is sleeved and fixedly connected to the output rod body of the electric telescopic rod 8 through bolts, the electric telescopic rod 8 is started to perform extension operation, and the pushing block 10 is driven to slide leftward in the right segment shell cavity of the shell frame 1;

[0049] Due to the "L" shaped structure of the adjusting frame 7, it is divided into two parts, the horizontal frame body and the longitudinal frame body, wherein the longitudinal frame body is towards the rear side, vertically arranged at the right end of the horizontal frame body, and wherein the horizontal frame body is in the shape of a square column, the adjusting frame 7 is placed and movably clamped in the right segment cavity of the shell frame 1, so that the adjusting frame 7 is positioned in the shell frame 1 in a movable state, and can only slide linearly. Due to the fact that the output rod body of the electric telescopic rod 8 is movably inserted through the horizontal frame body of the adjusting frame 7 after being placed, the center of the horizontal frame body of the adjusting frame 7 and the rod center of the output rod body of the electric telescopic rod 8 are on the same horizontal axis. When the electric telescopic rod 8 operates, the output rod body of the electric telescopic rod 8 slides in the horizontal frame body of the adjusting frame 7.

[0050] Due to the fact that the horizontal frame body of the adjusting frame 7 is provided with a spring compartment which is concentric with it, the first spring 9 is installed at the sliding connection between the adjusting frame 7 and the shell frame 1. The first spring 9 is movably inserted into the spring compartment of the adjusting frame 7 after being placed, and is connected with the output rod body of the electric telescopic rod 8 in a movable sleeving manner. One end of the first spring 9 abuts against the wall of the spring compartment of the adjusting frame 7, and the other end abuts against the wall of the right segment cavity of the shell frame 1. The pushing block 10 is connected with the right end of the adjusting frame 7 in an abutting manner after being driven to slide, and pushes the adjusting frame 7 to slide to the left in the right segment cavity of the shell frame 1, causing the first spring 9 to be compressed and elastically deformed.

[0051] Due to the fact that the middle position of the front side wall of the shell frame 1 is provided with a through sliding groove, the shell cavity of the shell frame 1 is connected with the shell cavity of the protective shell 101 through the sliding groove. Due to the fact that the front side of the left end of the horizontal frame body of the adjusting frame 7 is vertically provided with an integrated shaft column, the shaft column of the adjusting frame 7 is movably inserted through the sliding groove on the front side wall of the shell frame 1 to extend into the shell cavity of the protective shell 101 after being placed. When the adjusting frame 7 is driven to slide, the shaft column of the adjusting frame 7 slides in the shell cavity of the protective shell 101 along the sliding groove on the front side wall of the shell frame 1.

[0052] Due to the fact that the bearing is fixedly connected with the shaft center of the tensioning groove wheel 2, the tensioning groove wheel 2 is sleeved on the shaft column of the adjusting frame 7 after being placed, and is arranged in a movable positioning state. The adjusting frame 7 is driven to slide to the left, and the tensioning groove wheel 2 is synchronously slid to the left in the shell cavity of the protective shell 101.

[0053] Since the upper and lower of the tensioning groove wheel 2 are respectively provided with the incoming groove wheel 4 and the outgoing groove wheel 5, the incoming groove wheel 4 and the outgoing groove wheel 5 are on the same vertical central axis, the specifications of the two are the same, the distance between the tensioning groove wheel 2 and the incoming groove wheel 4 is equal to the distance between the tensioning groove wheel 2 and the outgoing groove wheel 5, that is, the tensioning groove wheel 2 is located at the midpoint of the gap between the incoming groove wheel 4 and the outgoing groove wheel 5, and since the specifications of the grooves in the incoming groove wheel 4 and the outgoing groove wheel 5 are the same as the specifications of the grooves in the tensioning groove wheel 2, the grooves in the three are matched with the electrode wire, the grooves in the incoming groove wheel 4 and the outgoing groove wheel 5 are on the same vertical plane with the grooves in the tensioning groove wheel 2, and since the tensioning groove wheel 2, the incoming groove wheel 4 and the outgoing groove wheel 5 are connected with the electrode wire in a winding and clamping manner, that is, the electrode wire is wound and clamped from the right side of the incoming groove wheel 4 to the left side of the tensioning groove wheel 2, and then from the left side of the tensioning groove wheel 2 to the right side of the outgoing groove wheel 5, after the tensioning groove wheel 2 slides to the left, the electrode wire is pushed by the tensioning groove wheel 2, the tensioning groove wheel 2, the incoming groove wheel 4 and the outgoing groove wheel 5 are combined to form an isosceles triangle, so that the tension generated after pushing is evenly distributed on both sides of the tensioning groove wheel 2, the stability of the electrode wire is improved, and the electrode wire is automatically tensioned by the cooperation of the tensioning groove wheel 2, the incoming groove wheel 4 and the outgoing groove wheel 5.

[0054] Specifically, in the technical solution, the tensioning groove wheel 2 after sliding adjustment is automatically locked, according to Figure 4 、 Figure 5 and Figure 6 , the adjusting frame 7 and the tensioning groove wheel 2 can be adjusted in a large range by the pushing and pressing of the pushing block 10, the included angle between the tensioning groove wheel 2, the incoming groove wheel 4 and the outgoing groove wheel 5 can be freely adjusted, and the electrode wire tensioning force can be freely adjusted according to different processing requirements.

[0055] Due to the "T" shape structure of the ratchet lock block 11, it is divided into two parts of horizontal block and longitudinal block, wherein the horizontal block is towards the rear side, and is vertically arranged in the middle of the longitudinal block, and the end of the horizontal block is the ratchet end, the ratchet lock block 11 is arranged in the slot cavity of the longitudinal frame of the adjusting frame 7, and the ratchet end of the ratchet lock block 11 is inserted through the rear slot cavity wall of the longitudinal frame of the adjusting frame 7 and extends outward, and the "T" shape structure of the ratchet lock block 11 is arranged to be in a movable state on the longitudinal frame of the adjusting frame 7, and due to the arrangement of the ratchet rack 13 in the right cavity wall of the shell frame 1, the ratchet rack 13 is locked in the state by the clamping and locking of the U-shaped lock frame 30 on the connecting column 27, and due to the through sliding groove on the rear cavity wall of the right cavity of the shell frame 1, the ratchet end of the horizontal block of the ratchet lock block 11 is inserted through the sliding groove on the right cavity wall of the shell frame 1 and extends into the right cavity wall, and the ratchet end of the horizontal block is connected with the ratchet rack 13, when the adjusting frame 7 is driven to slide left, the ratchet end of the ratchet lock block 11 slides along the ratchet of the ratchet rack 13, and the ratchet lock block 11 is stretched and retracted at the rear end of the longitudinal frame of the adjusting frame 7.

[0056] Due to the spring cavity on the upper and lower sides of the longitudinal block of the ratchet lock block 11, the second spring 12 is installed at the sliding connection between the ratchet lock block 11 and the adjusting frame 7, the second spring 12 is symmetrically arranged about the horizontal axis of the ratchet lock block 11, the second spring 12 is arranged in the spring cavity of the ratchet lock block 11, one end of the second spring 12 is pressed against the spring cavity wall of the ratchet lock block 11, and the other end of the second spring 12 is pressed against the slot cavity wall of the longitudinal frame of the adjusting frame 7, and due to the size of the ratchet of the ratchet rack 13 being matched with the size of the ratchet end of the ratchet lock block 11, when the ratchet end of the ratchet lock block 11 is pushed by the ratchet of the ratchet rack 13 and retracts at the rear end of the longitudinal frame of the adjusting frame 7, the second spring 12 is elastically deformed under the extrusion, and when the ratchet end of the ratchet lock block 11 is not pushed by the ratchet of the ratchet rack 13, the second spring 12 is reset by elastic deformation, the ratchet end of the ratchet lock block 11 is locked between the two ratchets of the ratchet rack 13, and the adjusting frame 7 is driven to slide left, the ratchet lock block 11 is connected with the ratchet rack 13, and the adjusting frame 7 is locked by the elastic deformation reset of the first spring 9, that is, the automatic locking operation after the sliding adjustment of the tensioning groove wheel 2 is completed, and the stable tensioning force of the tensioning groove wheel 2 on the electrode wire is ensured.

[0057] Specifically, in the technical scheme, the monitoring assembly 6 is arranged in a sliding state on the left shell wall of the shell frame 1, and is driven by the adjusting assembly 3, and the real-time monitoring and measurement of the tensioning force during the electrode wire tensioning adjustment is realized by the monitoring assembly 6, and the tensioning force is adjusted according to theFigure 1 , Figure 2 and Figure 4 As shown, when the pushing block 10 slides against the pushing adjustment frame 7, the tensioning groove wheel 2 initially tensions the electrode wire. At this time, the limiting component 21 is placed outside the square column 17, causing the electric telescopic rod 8 to retract and operate. The limiting component 21 can push the square column 17, ensuring that the adjustment component 3 can drive the monitoring component 6 in conjunction. In addition, at this time, the gap formed between the pushing block 10 and the U-shaped lock frame 30 is much larger than the maximum sliding distance of the square column 17, so that when the electric telescopic rod 8 retracts and operates, the pushing block 10 will not contact the U-shaped lock frame 30, and the ratchet frame 13 will not be unlocked, ensuring that the tensioning groove wheel 2 is locked in the position after sliding adjustment.

[0058] In this way, the adjusting component 3 drives the tensioning groove wheel 2 to continuously tension the electrode wire. During the tensioning process, the adjusting component 3 drives the monitoring component 6 to monitor the tension of the electrode wire in real time. The two work together to make fine adjustments to the tension of the electrode wire under real-time monitoring, so as to achieve dynamic and precise adjustment. In addition, during the use of the electrode wire, the adjusting component 3 drives the monitoring component 6 to measure the tension of the electrode wire and record the changes in the tension of the electrode wire in real time, so as to make real-time tension adjustments.

[0059] Specifically, in this technical solution, the monitoring component 6 is used to monitor the electrode wire tension. Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a limiting component 21 for pushing its movement is provided on the left side of the square column 17. The limiting component 21 includes a round tube shell 22 and a limiting claw 23. Since the telescopic electromagnet 25 is connected to the external circuit through the spring wire, it is inserted into the cavity of the round tube shell 22 after installation and fixed by bolts. Since the rack column 24 is movably locked in the cavity of the round tube shell 22 after installation, and it is sleeved and fixedly connected to the output end of the telescopic electromagnet 25 by bolts, the telescopic electromagnet 25 is started to extend and operate, driving the rack column 24 to slide to the right in the cavity of the round tube shell 22.

[0060] Since the inward end of the limiting claw 23 close to the one end of the cylindrical shell 22 is the inward end, and the end away from the cylindrical shell 22 is the outward end, the limiting claw 23 is symmetrically arranged about the horizontal central axis of the cylindrical shell 22, and the two limiting claws 23 are oppositely arranged. Since the inward end of the limiting claw 23 is provided with an integrated gear part, and the two sides of the rack column 24 are provided with racks, the two racks correspond to the gear parts of the two limiting claws 23, respectively. The gear part of the limiting claw 23 is connected to the rack column 24 in a meshing manner. When the rack column 24 is driven to slide to the right, the limiting claw 23 is driven to move through the meshing action between the rack column 24 and the gear part of the limiting claw 23.

[0061] Since the inward end of the limiting claw 23 is connected to the shaft column through the bearing auxiliary rotation, the inward end of the limiting claw 23 is movably clamped in the lumen of the cylindrical shell 22 after being placed, and the both ends of the shaft column are respectively inserted and fixedly connected to the lumen walls on both sides of the cylindrical shell 22 through bolts. When the limiting claw 23 is driven, it is turned and unfolded on the cylindrical shell 22, and the two limiting claws 23 are unfolded in opposite directions.

[0062] Since the square column 17 is movably inserted into the output rod body of the electric telescopic rod 8 after being placed, the center of the square column 17 and the rod center of the output rod body of the electric telescopic rod 8 are on the same horizontal central axis. When the electric telescopic rod 8 is started to operate in a contraction mode, the pushing block 10 is driven to slide to the right in the right segment cavity of the shell frame 1. When the pushing block 10 slides to the right, it loses the pressing effect on the adjusting frame 7. At this time, the adjusting frame 7 is in a locked state through the engagement connection between the ratchet lock block 11 and the ratchet rack 13, and the elastic deformation reset of the first spring 9. Even if the tensioning groove wheel 2 is locked in the state after sliding adjustment, the output rod body of the electric telescopic rod 8 slides in the transverse frame body of the adjusting frame 7, and the output rod body of the electric telescopic rod 8 slides to the right on the square column 17 when the electric telescopic rod 8 operates in a contraction mode.

[0063] Since the limiting assembly 21 and the output rod body of the electric telescopic rod 8 are on the same horizontal central axis, they constitute a synchronous motion structure. The cylindrical shell 22 is inserted and fixedly connected to the left end of the output rod body of the electric telescopic rod 8 through bolts after being placed. When the output rod body of the electric telescopic rod 8 slides to the right on the square column 17, the unfolded limiting claw 23 is connected to the square column 17 in a pressing and pushing manner. When the electric telescopic rod 8 continues to operate in a contraction mode, the outward end of the limiting claw 23 presses against the left side wall of the square column 17, and the square column 17 is pushed to move synchronously.

[0064] Since the square column 17 is arranged in the left segment cavity of the shell frame 1, the square column 17 is positioned in the shell frame 1 in a movable state and can only slide linearly. Since the square column 17 is provided with a spring compartment concentric with the square column 17, the square column 17 is provided with the third spring 18 at the sliding connection with the shell frame 1. The third spring 18 is arranged in the spring compartment of the square column 17 in a movable manner. The third spring 18 is connected to the output rod of the electric telescopic rod 8 in a movable sleeving manner. One end of the third spring 18 abuts against the wall of the spring compartment of the square column 17. The other end of the third spring 18 abuts against the wall of the left segment cavity of the shell frame 1. When the square column 17 is pushed, the square column 17 slides to the right in the left segment cavity of the shell frame 1. The third spring 18 is squeezed and elastically deformed.

[0065] Since the U-shaped frame 14 is composed of a longitudinal frame body and two transverse frame bodies arranged vertically on the upper and lower sides of the longitudinal frame body, the longitudinal frame body of the U-shaped frame 14 is arranged on the rear side wall of the shell frame 1. The upper and lower transverse frame bodies of the U-shaped frame 14 are arranged on the upper and lower side walls of the shell frame 1 in a movable manner. The U-shaped frame 14 is positioned on the shell frame 1 in a movable state. Since the rear side wall of the left segment of the shell frame 1 is provided with a sliding groove in a through state, the front side of the longitudinal frame body of the U-shaped frame 14 is provided with a protruding block part in an integrated structure. The protruding block part of the U-shaped frame 14 is arranged in the sliding groove of the rear side wall of the shell frame 1 in a movable manner. The protruding block part of the U-shaped frame 14 is connected to the square column 17 in a clamping and screwing manner. The U-shaped frame 14 and the square column 17 form a synchronous sliding structure. When the square column 17 is driven to slide to the right, the U-shaped frame 14 slides to the right on the left segment wall of the shell frame 1. The monitoring assembly 6 slides horizontally to the electrode wire.

[0066] Since the monitoring assembly 6 includes the U-shaped frame 14, the first detection claw 15 arranged on the upper side of the U-shaped frame 14, and the second detection claw 16 arranged on the lower side of the U-shaped frame 14, the right end of the first detection claw 15 and the right end of the second detection claw 16 are rotatably connected to grooved wheels. The grooved wheel of the first detection claw 15 is above the wire inlet grooved wheel 4. The grooves of the two are in the same vertical plane. The grooved wheel of the second detection claw 16 is below the wire outlet grooved wheel 5. The grooves of the two are also in the same vertical plane. Since the grooved wheel of the first detection claw 15 and the grooved wheel of the second detection claw 16 are connected to the electrode wire in a clamping manner, when the U-shaped frame 14 is driven to slide to the right, the grooved wheel of the first detection claw 15 clamps against the entering section of the electrode wire for tension monitoring of the entering section of the electrode wire. The grooved wheel of the second detection claw 16 clamps against the going-out section of the electrode wire for tension monitoring of the going-out section of the electrode wire. When the U-shaped frame 14 is driven to slide to the right, the entering section and the going-out section of the electrode wire push the first detection claw 15 and the second detection claw 16 to move.

[0067] The left end of the first detection claw 15 is connected with a shaft column through bearing auxiliary rotation, the shaft column is inserted into the connecting seat on the upper horizontal frame body of the U-shaped frame 14 and fixed by bolts, the second detection claw 16 has the same structure shape as the first detection claw 15, and the installation mode is the same, the shaft column of the second detection claw 16 is inserted into the connecting seat on the lower horizontal frame body of the U-shaped frame 14 and fixed by bolts, the first detection claw 15 and the second detection claw 16 are oppositely arranged, and the first detection claw 15 and the second detection claw 16 form an "eight" structure, when the first detection claw 15 is pushed, the shaft column can rotate and overturn on the upper side of the U-shaped frame 14, when the second detection claw 16 is pushed, the shaft column can rotate and overturn on the lower side of the U-shaped frame 14, so that the overturning direction of the first detection claw 15 is opposite to the overturning direction of the second detection claw 16.

[0068] The left end of the first detection claw 15 is connected with a shaft column through bearing auxiliary rotation, the shaft column is inserted into the connecting seat on the upper horizontal frame body of the U-shaped frame 14 and fixed by bolts, the second detection claw 16 has the same structure shape as the first detection claw 15, and the installation mode is the same, the shaft column of the second detection claw 16 is inserted into the connecting seat on the lower horizontal frame body of the U-shaped frame 14 and fixed by bolts, the first detection claw 15 and the second detection claw 16 are oppositely arranged, and the first detection claw 15 and the second detection claw 16 form an "eight" structure, when the first detection claw 15 is pushed, the shaft column can rotate and overturn on the upper side of the U-shaped frame 14, when the second detection claw 16 is pushed, the shaft column can rotate and overturn on the lower side of the U-shaped frame 14, so that the overturning direction of the first detection claw 15 is opposite to the overturning direction of the second detection claw 16.

[0069] The left end of the first detection claw 15 is connected with a shaft column through bearing auxiliary rotation, the shaft column is inserted into the connecting seat on the upper horizontal frame body of the U-shaped frame 14 and fixed by bolts, the second detection claw 16 has the same structure shape as the first detection claw 15, and the installation mode is the same, the shaft column of the second detection claw 16 is inserted into the connecting seat on the lower horizontal frame body of the U-shaped frame 14 and fixed by bolts, the first detection claw 15 and the second detection claw 16 are oppositely arranged, and the first detection claw 15 and the second detection claw 16 form an "eight" structure, when the first detection claw 15 is pushed, the shaft column can rotate and overturn on the upper side of the U-shaped frame 14, when the second detection claw 16 is pushed, the shaft column can rotate and overturn on the lower side of the U-shaped frame 14, so that the overturning direction of the first detection claw 15 is opposite to the overturning direction of the second detection claw 16.

[0070] According to the above, conversely, the electric telescopic rod 8 is stretched and operated, the limiting component 21 pushes the square column 17, the elastic deformation of the third spring 18 is reset, the square column 17 drives the U-shaped frame 14 to slide to the left, and the groove wheels in the first detection claw 15 and the second detection claw 16 are separated from the entering section and the leaving section of the electrode wire.

[0071] Specifically, in the technical solution, the electrode wire is arranged in the tight wire adjusting structure, according to Figure 1 、 Figure 2 and Figure 3 , the protective shell 101 is vertically arranged in the middle position of the front shell wall of the shell frame 1 in an integrated structure, and the upper and lower ends of the shell cavity in the protective shell 101 are both arranged in an open state. The upper end opening of the shell cavity is an entrance, and the lower end opening of the shell cavity is an exit. When the electrode wire is arranged, the electrode wire enters the shell cavity of the protective shell 101 from the entrance of the protective shell 101, and then successively winds and clamps the right side of the wire inlet groove wheel 4, the left side of the tension groove wheel 2 and the right side of the wire outlet groove wheel 5. After the electrode wire passes through the shell cavity of the protective shell 101, the electrode wire is inserted to the outside from the exit of the protective shell 101.

[0072] Since the upper end of the shell cavity wall in the protective shell 101 is vertically provided with an integrated structure of the shaft column, the bearing is fixedly connected at the wheel core of the wire inlet groove wheel 4. After the wire inlet groove wheel 4 is arranged, the bearing is sleeved on the upper end shaft column of the protective shell 101, and is arranged in an active positioning state. The wire inlet groove wheel 4 is arranged on the upper end shaft column of the protective shell 101 to form a rotating structure. Since the lower end of the shell cavity wall in the protective shell 101 is also vertically provided with an integrated structure of the shaft column, the bearing is fixedly connected at the wheel core of the wire outlet groove wheel 5. After the wire outlet groove wheel 5 is arranged, the bearing is sleeved on the lower end shaft column of the protective shell 101, and is arranged in an active positioning state. The wire outlet groove wheel 5 is arranged on the lower end shaft column of the protective shell 101 to form a rotating structure. Since the tension groove wheel 2 is arranged on the shaft column of the adjusting frame 7 to form a rotating structure, the rotating tension groove wheel 2, the wire inlet groove wheel 4 and the wire outlet groove wheel 5 assist the smooth operation of the electrode wire.

[0073] In the second embodiment, on the basis of the first embodiment, please refer to the technical solution shown in Figures 11-13 , in the existing electrode wire tight wire adjusting mechanism, the tension wheel, the outlet wheel and the inlet wheel are usually arranged in a triangular shape. The tension wheel cooperates with the outlet wheel and the inlet wheel to work, so as to realize the tensioning and guiding of the electrode wire, and to cope with the arrangement operation of the electrode wire in the tight wire mechanism. Due to the staggered arrangement of the tension wheel, the outlet wheel and the inlet wheel, the electrode wire is difficult to successively wind and insert through the inlet wheel, the tension wheel and the outlet wheel, and the arrangement operation is relatively cumbersome. The pushing block 10 is first connected with the U-shaped lock frame 30, the U-shaped lock frame 30 is unlocked from the connecting column 27, the pushing block 10 is then connected with the L-shaped frame 28, the sliding cooperation between the pin bolt 2701 and the inclined groove 1301 is used to unlock the clamping connection between the ratchet bar frame 13 and the ratchet lock block 11, the elastic deformation reset of the first spring 9 is used to unlock the adjusting frame 7 to drive the tension groove wheel 2 to reset and slide, and the tension groove wheel 2 is separated from the wire inlet groove wheel 4 and the wire outlet groove wheel 5 to assist the convenient insertion of the electrode wire during the arrangement of the electrode wire.

[0074] Specifically, in the convenient electrode wire placement operation, according to Figure 11 、 Figure 12 and Figure 13 , the telescopic electromagnet 25 is started to operate, the rack column 24 is driven to slide left in the tube cavity of the circular tube shell 22, the limit pawl 23 is driven to turn and close on the circular tube shell 22 through the meshing between the rack column 24 and the gear part of the limit pawl 23, the limit pawl 23 is received in the tube cavity of the circular tube shell 22 after turning and closing, and does not affect the insertion of the circular tube shell 22 and the square column 17. Since the diameter size of the circular tube shell 22 is the same as that of the output rod body of the electric telescopic rod 8, the electric telescopic rod 8 is started to operate, the circular tube shell 22 can follow the output rod body of the electric telescopic rod 8 to insert in the square column 17, and the pushing block 10 is reset to slide right in the right section cavity of the shell frame 1 after the telescopic operation of the electric telescopic rod 8;

[0075] Since the rear end of the right side wall of the pushing block 10 is provided with an inclined side wall, and the left side of the L-shaped frame 28 is provided with a U-shaped lock frame 30 for locking the connecting column 27, the U-shaped lock frame 30 is composed of a longitudinal frame body and two transverse frame bodies, the two transverse frame bodies are vertically arranged on the upper and lower sides of the longitudinal frame body, and the end of the transverse frame body is provided in a hemispherical structure. The U-shaped lock frame 30 is arranged and movably clamped in the right section cavity wall of the shell frame 1, the two transverse frame bodies are movably inserted into the right section cavity wall of the shell frame 1 and extend into the right section cavity of the shell frame 1, and correspond to the inclined side wall of the pushing block 10. When the pushing block 10 is reset to slide right, it is first connected with the U-shaped lock frame 30, the inclined side wall of the pushing block 10 is connected with the hemispherical end of the transverse frame body of the U-shaped lock frame 30 in a pressing manner, the hemispherical end of the transverse frame body of the U-shaped lock frame 30 slides along the inclined side wall of the pushing block 10 to the rear side wall of the pushing block 10, and the U-shaped lock frame 30 is pushed to shrink and slide in the right section cavity wall of the shell frame 1;

[0076] Since the two transverse frame bodies of the U-shaped lock frame 30 are provided with integrated limit discs, the U-shaped lock frame 30 is movably connected with the shell frame 1 and provided with a sixth spring 31, the sixth spring 31 is symmetrically arranged about the horizontal axis of the U-shaped lock frame 30, and the two sixth springs 31 are arranged on the two transverse frame bodies of the U-shaped lock frame 30. The sixth spring 31 is movably sleeved on the transverse frame body of the U-shaped lock frame 30, one end of the sixth spring 31 is pressed against the limit disc of the transverse frame body of the U-shaped lock frame 30, and the other end of the sixth spring 31 is pressed against the right section cavity wall of the shell frame 1. After the U-shaped lock frame 30 shrinks and slides, the longitudinal frame body of the U-shaped lock frame 30 loses the clamping connection with the connecting column 27, the locking of the connecting column 27 is released, and the sixth spring 31 is elastically deformed under the extrusion;

[0077] Because the length dimension of the pushing block 10 is greater than the interval dimension between the U-shaped lock frame 30 and the sliding rear L-shaped frame 28, the U-shaped lock frame 30 is unlocked from the locking of the linkage column 27, and when the pushing block 10 continuously resets and slides to the right and is butted against the L-shaped frame 28, the hemispherical end of the transverse frame body of the U-shaped lock frame 30 slides along the rear side wall of the pushing block 10, and the unlocking state of the U-shaped lock frame 30 is maintained;

[0078] Because the L-shaped frame 28 is divided into a transverse frame body and a longitudinal frame body, the longitudinal frame body is vertically arranged at the left end of the transverse frame body and is movably clamped in the right segment cavity wall of the shell frame 1, the longitudinal frame body movably penetrates through the right segment cavity wall of the shell frame 1 and extends into the right segment cavity of the shell frame 1 and corresponds to the right side wall of the pushing block 10, and because the fifth spring 29 is arranged at the sliding connection position of the L-shaped frame 28 and the shell frame 1, the fifth spring 29 is movably clamped in the right segment cavity wall of the shell frame 1, one end of the fifth spring 29 abuts against the transverse frame body of the L-shaped frame 28, and the other end of the fifth spring 29 abuts against the right segment cavity wall of the shell frame 1, when the pushing block 10 continuously resets and slides to the right and is butted against the L-shaped frame 28, the right side wall of the pushing block 10 is connected to the longitudinal frame body of the L-shaped frame 28 in an abutting manner, the L-shaped frame 28 is pushed by the pushing block 10 to slide to the right in the right segment cavity wall of the shell frame 1, and the fifth spring 29 is elastically deformed under the extrusion;

[0079] Because the upper and lower ends of the side away from the ratchet lock block 11 of the ratchet frame 13 are vertically provided with integrated limiting plate parts, the right segment of the linkage column 27 is movably clamped in the right segment cavity wall of the shell frame 1, and the left segment of the linkage column 27 is movably clamped in the gap between the upper and lower limiting plate parts of the ratchet frame 13, and because the right end of the linkage column 27 is clamped and fixedly connected to the transverse frame body of the L-shaped frame 28 by a bolt after the linkage column 27 is arranged, the linkage column 27 and the L-shaped frame 28 form a synchronous sliding structure, when the L-shaped frame 28 is driven to slide to the right, the linkage column 27 slides to the right in the right segment cavity wall of the shell frame 1, and the linkage column 27 forms a sliding structure between the two limiting plate parts of the ratchet frame 13;

[0080] The inclined grooves 1301 are equidistantly arranged on the limiting plate of the ratchet rack 13 in a through state, the inclined groove 1301 on the upper end limiting plate corresponds to the inclined groove 1301 on the lower end limiting plate, the pin 2701 is equidistantly arranged on the connecting column 27, and the upper and lower ends of the pin 2701 are outwardly arranged after being fixed on the connecting column 27 by the bolt, each pin 2701 corresponds to each inclined groove 1301, and the upper and lower ends of the pin 2701 are movably arranged in the inclined grooves 1301 on the upper end limiting plate and the inclined grooves 1301 on the lower end limiting plate after being arranged, and the connecting column 27 is driven to slide to the right, so that the pin 2701 slides along the inclined groove 1301.

[0081] The ratchet rack 13 is movably arranged in the right shell cavity wall of the shell rack 1, the ratchet rack 13 is equidistantly arranged with spring compartments on the side away from the ratchet tooth lock block 11, the spring compartments are symmetrically arranged above and below the horizontal central axis of the ratchet rack 13, the fourth spring 26 is arranged on the sliding connection between the ratchet rack 13 and the shell rack 1, the fourth spring 26 is equidistantly arranged on the ratchet rack 13 and symmetrically arranged above and below the horizontal central axis of the ratchet rack 13, the fourth spring 26 is movably arranged in the spring compartment of the ratchet rack 13 after being arranged, one end of the fourth spring 26 is abutted against the spring compartment wall of the ratchet rack 13, the other end of the fourth spring 26 is abutted against the right shell cavity wall of the shell rack 1, the ratchet rack 13 is slid in the right shell cavity wall of the shell rack 1 through the sliding cooperation between the pin 2701 and the inclined groove 1301, the fourth spring 26 is elastically deformed by being pressed, the ratchet rack 13 is disconnected with the ratchet tooth lock block 11 after being slid, and the adjustment rack 7 is unlocked.

[0082] When the adjustment rack 7 is unlocked, the adjustment rack 7 drives the tensioning groove wheel 2 to slide to the right in the shell cavity of the protective shell 101 through the elastic deformation of the first spring 9, the tensioning groove wheel 2 is separated from the wire feeding groove wheel 4 and the wire outlet groove wheel 5, the electrode wire can be conveniently inserted through the protective shell 101 and can be conveniently wound and clamped on the tensioning groove wheel 2, the wire feeding groove wheel 4 and the wire outlet groove wheel 5, and the convenient arrangement of the electrode wire is completed.

[0083] Conversely, after the push block 10 is driven to move, it loses its connection with the L-shaped frame 28. The elastic deformation of the fifth spring 29 resets the L-shaped frame 28 and the linkage column 27, causing them to slide back to their original positions within the right section of the outer shell 1. Then, through the sliding engagement between the pin 2701 and the inclined groove 1301, and through the elastic deformation of the fourth spring 26, the ratchet frame 13 slides back to its original position within the right section of the outer shell 1. After the push block 10 continues to move, it loses its connection with the U-shaped lock frame 30. The elastic deformation of the sixth spring 31 resets the U-shaped lock frame 30, causing it to slide back to its original position within the right section of the outer shell 1. The longitudinal frame of the U-shaped lock frame 30 is then re-engaged with the linkage column 27, locking the ratchet frame 13 after reset.
