Description

Technical Field

[0001] This invention relates to the technical field of wire EDM machine tools, specifically to a wire tensioning adjustment mechanism for wire EDM machine tools. Background Technology

[0002] Wire electrical discharge machining (EDM) machines use molybdenum wire or bobbin wire as electrode wire. High temperatures are generated through pulsed discharge between the electrode wire and the workpiece. The workpiece material is melted and cut along a preset trajectory using a fast or slow wire feed continuous movement method. It is widely used in mold manufacturing, medical devices, aerospace and other fields. In the use of wire EDM machines, in order to prevent problems such as wire tangling and slippage from the guide rollers due to insufficient electrode wire tension, and to prevent increased vibration amplitude during cutting due to insufficient electrode wire tension, which affects machining accuracy, it is necessary to adjust the tension of the electrode wire through a tensioning mechanism.

[0003] A search of the invention patent with authorization announcement number CN109365935B reveals a wire tensioning mechanism, including a support panel. The upper end of the support panel is provided with an inlet guide wheel for winding molybdenum wire, and an outlet guide wheel that is arranged opposite to the inlet guide wheel at a preset distance for winding out molybdenum wire. The mechanism also includes a tensioning guide wheel that is configured to cooperate with the inlet and outlet guide wheels to generate tension force to tension the molybdenum wire and prevent it from breaking, and an elastic mechanism that is connected to the side of the support panel to drive the tensioning guide wheel to extend and retract along the side perpendicular to the support panel.

[0004] Based on the aforementioned patents, existing solutions, and practical application, the wire tension adjustment mechanism in current wire EDM machines still has some problems, such as: In the aforementioned patent, the tension guide wheel is driven to move outward by the elastic force of the spring component. The electrode wire is automatically tightened through the cooperation between the tension guide wheel, the infeed guide wheel, and the outfeed guide wheel. However, relying on the elastic force of the spring component for the tightening operation can easily lead to fatigue and plastic deformation of the spring component, which affects the stability of the tension force in the tightening mechanism. In addition, the elastic coefficient of the spring component is fixed, which means that the tension guide wheel can only move within a limited range, thus limiting the adjustment range of the tension force. The existing electrode wire tensioning mechanism uses a manual tensioning adjustment method, which is cumbersome to operate. Moreover, the existing tensioning mechanism, like the tensioning mechanism in the aforementioned patent, cannot achieve real-time monitoring and measurement of the electrode wire tension during the adjustment process, thus failing to achieve the purpose of dynamic and precise adjustment.

[0005] Therefore, we propose a wire tensioning adjustment mechanism for wire EDM machines to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a wire tension adjustment mechanism for wire EDM machines, in order to solve the problems mentioned in the background art, such as the inability to achieve real-time monitoring and measurement of electrode wire tension during the electrode wire tension adjustment process, thus failing to achieve the purpose of dynamic and precise adjustment, and the limited adjustment range of tension, which affects the ease of operation.

[0012] Preferably, the flipping direction of the first detection claw is opposite to that of the second detection claw, and the grooved wheel in the first detection claw and the grooved wheel in the second detection claw are respectively used for monitoring the electrode wire entry section and exit section. The deflector portion in the first detection claw and the deflector portion in the second detection claw are respectively connected to the upper and lower ends of the linkage frame in a sliding manner, and the linkage frame is fixedly connected to the tension sensor fixedly installed on the U-shaped frame.

[0013] Preferably, a limiting component for pushing its movement is provided on the left side of the square column, and the limiting component and the output rod in the electric telescopic rod form a synchronous movement structure. The limiting component includes a circular tube shell fixed to the end of the output rod in the electric telescopic rod and limiting claws symmetrically arranged about the horizontal central axis of the circular tube shell. The limiting claws form a flipping structure on the circular tube shell, and the limiting claws are connected to the square column by a pressing and pushing method. The limiting claw has an integrated gear section at its inner end, and the gear section in the limiting claw is connected to the rack column fixed to the output end of the telescopic electromagnet in an engaging manner, and the telescopic electromagnet is fixed inside the cavity of the cylindrical shell.

[0014] Preferably, the ratchet frame forms a sliding structure within the right section of the outer shell cavity wall, which releases the locking of the adjusting frame and uses the adjusting frame to drive the tension groove wheel to separate from the wire feed groove wheel and the wire output groove wheel. A fourth spring is installed at the sliding connection between the ratchet frame and the outer shell frame. A connecting column is slidably connected within the right section of the outer shell cavity wall, and a pin is fixedly connected to the connecting column. The pin is slidably connected to the inclined groove opened on the limiting plate portion in the ratchet frame. The right end of the linkage column is fixedly connected to an L-shaped frame, and the linkage column and the L-shaped frame together form a synchronous sliding structure in the right section of the shell cavity wall of the outer shell frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the wire tensioning adjustment mechanism of the wire EDM machine tool realizes real-time monitoring and measurement of the electrode wire tension during the electrode wire tensioning adjustment process, meets the purpose of dynamic and precise adjustment of tension, and, in conjunction with automated wire tensioning, achieves the requirement of maintaining stable electrode wire tension, ensuring ease of operation; 1. The electrode wire is sequentially wound and engaged with the right side of the feed groove wheel, the left side of the tension groove wheel, and the right side of the output groove wheel. The tension groove wheel is automatically adjusted by the adjustment component. Through the cooperation between the tension groove wheel, the feed groove wheel, and the output groove wheel, the electrode wire is automatically tensioned. During the electrode wire tension adjustment process, the adjustment component drives the monitoring component to achieve real-time monitoring and measurement of the electrode wire tension, which meets the purpose of dynamic and precise tension adjustment. In addition, the monitoring component is set to meet the requirement of periodic tension checks. After the check, the automatic wire tightening is achieved to maintain a stable electrode wire tension, reduce manual intervention, and ensure automation performance. Furthermore, the adjusting frame drives the tensioning groove wheel to slide and adjust, freely adjusting the included angle between the tensioning groove wheel and the wire feeding groove wheel and the included angle between the tensioning groove wheel and the wire exit groove wheel, so as to realize the applicability of the electrode wire tension force to freely adjust. After the adjusting frame drives the tensioning groove wheel to slide and adjust, the locking action between the ratchet locking block and the ratchet frame is used to lock the tensioning groove wheel after tension adjustment, ensuring that the electrode wire can form a stable tension force. Furthermore, the grooved wheel in the first detection claw is positioned above the wire feed grooved wheel, and the grooved wheel in the second detection claw is positioned below the wire exit grooved wheel. After the U-shaped frame is driven to slide, the grooved wheels in the first and second detection claws respectively abut against the entry and exit sections of the electrode wire, thereby achieving synchronous monitoring of the tension force in the entry and exit sections of the electrode wire and ensuring the accuracy of tension force monitoring. 2. The pushing block engages with the U-shaped locking frame, causing the U-shaped locking frame to slide under the push and release its locking to the linkage column. The pushing block engages with the L-shaped frame, causing the L-shaped frame to slide synchronously with the linkage column under the push. Through the sliding fit between the pin and the inclined groove, the ratchet frame is driven to slide and release its locking to the ratchet locking block. The elastic deformation of the first spring resets the adjustment frame, causing the tensioning groove wheel, the wire feed groove wheel, and the wire output groove wheel to slide and separate. Through the linkage structure, the tensioning groove wheel is separated from the wire feed groove wheel and the wire output groove wheel, avoiding the interference of the staggered tensioning groove wheel, wire feed groove wheel, and wire output groove wheel on the insertion of the electrode wire. The open placement method facilitates the convenient insertion and winding of the electrode wire, ensuring ease of operation. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: This invention provides a technical solution: a wire tension adjustment mechanism for a wire EDM machine. During the wire tension adjustment process, it addresses the problems of inability to automatically adjust, inability to achieve real-time monitoring and measurement of the wire tension during adjustment, and inability to achieve dynamic and precise adjustment. Furthermore, it addresses the issues of limited adjustment range of the wire tension for different processing requirements and insufficient stability of the tension after adjustment. Through the pushing action between the push block 10 and the adjustment frame 7, the push block 10, driven by the electric telescopic rod 8, causes the adjustment frame 7 to slide along the tension groove wheel 2. This movement occurs through the tension groove wheel 2, the wire feed groove wheel 4, and the wire output groove... The coordination between the three components (wheel 5, wheel 6, and wheel 7) automatically tensions the electrode wire. By adjusting the position of the tensioning groove wheel 2, the applicable tension force of the electrode wire can be freely adjusted. During the sliding process of the tensioning groove wheel 2 driven by the adjusting frame 7, the locking action between the ratchet locking block 11 and the ratchet frame 13 is used to lock the tensioning groove wheel 2 after the sliding adjustment, ensuring the stability of the tension force after the electrode wire is tensioned by the tensioning groove wheel 2. In addition, the tensioning groove wheel 2 is driven by the adjusting component 3 to tension the electrode wire. The adjusting component 3 drives the monitoring component 6 in conjunction with the adjusting component 3, and the monitoring component 6 is used to monitor and measure the tension force in real time during the electrode wire tension adjustment.

[0021] This technical solution: Please refer to Figures 1-10 A wire tensioning adjustment mechanism for a wire EDM machine includes a housing frame 1. An integrated connecting plate is vertically provided on the right end of the rear side shell wall of the housing frame 1. When the wire tensioning adjustment mechanism is installed, the connecting plate in the housing frame 1 is fixedly connected to the preset position of the wire EDM machine by bolts. A protective shell 101 for electrode wire insertion is provided on the front side shell wall of the housing frame 1. It also includes a tensioning groove wheel 2 and a monitoring component 6. The tensioning groove wheel 2 forms a sliding adjustment structure within the protective shell 101 through the drive of the adjustment component 3. The adjustment component 3 is located in the right section of the outer shell 1 and is set parallel to the outer shell 1. Above the tensioning groove wheel 2 is a wire feeding groove wheel 4 that can rotate within the protective shell 101, and below the tensioning groove wheel 2 is a wire output groove wheel 5 that can rotate within the protective shell 101. Through the cooperation between the tensioning groove wheel 2, the wire feeding groove wheel 4, and the wire output groove wheel 5, the electrode wire is automatically and stably tensioned. In addition, the electrode wire tension can be freely adjusted adaptively through the sliding adjustment of the tensioning groove wheel 2. The monitoring component 6 is set in a sliding state on the left section of the outer shell 1. It is driven by the adjustment component 3 and performs real-time monitoring and measurement of the tension during the electrode wire tension adjustment.

[0022] Specifically, in this technical solution, the electrode wire is automatically tensioned via the tensioning groove wheel 2, according to... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the adjustment assembly 3 includes an adjustment frame 7 and an electric telescopic rod 8. The adjustment assembly 3 drives the tensioning groove wheel 2 to perform linear sliding motion in a horizontal state. After the electric telescopic rod 8 is installed, it is fixedly installed on the right side shell wall of the outer shell frame 1 by bolts and is set in a parallel state with the outer shell frame 1. The output rod body extends from the right section shell cavity of the outer shell frame 1 to the left section shell cavity of the outer shell frame 1. Since the pushing block 10 is set in a square structure, it is movably locked in the right section shell cavity of the outer shell frame 1 after installation, and it is sleeved and fixedly connected to the output rod body of the electric telescopic rod 8 by bolts. When the electric telescopic rod 8 is started to extend and operate, it drives the pushing block 10 to slide to the left in the right section shell cavity of the outer shell frame 1. Because the adjusting frame 7 is set in an "L" shape, it is divided into two parts: a horizontal frame and a vertical frame. The vertical frame faces the rear and is set vertically at the right end of the horizontal frame. The horizontal frame is square column-shaped. After the adjusting frame 7 is installed, it is movably locked in the right section of the outer shell cavity of the outer shell 1, so that the adjusting frame 7 is positioned in a movable state within the outer shell 1 and can only slide linearly. After the electric telescopic rod 8 is installed, the output rod moves through the horizontal frame of the adjusting frame 7, so that the center of the horizontal frame of the adjusting frame 7 and the center of the output rod of the electric telescopic rod 8 are on the same horizontal central axis. When the electric telescopic rod 8 is operating, the output rod of the electric telescopic rod 8 slides within the horizontal frame of the adjusting frame 7. Since the horizontal frame of the adjusting frame 7 has a spring compartment with the same center, a first spring 9 is installed at the sliding connection between the adjusting frame 7 and the outer shell frame 1. After the first spring 9 is installed, it is movably inserted into the spring compartment of the adjusting frame 7. It is connected to the output rod of the electric telescopic rod 8 by a movable sleeve. One end of it presses against the wall of the spring compartment in the adjusting frame 7, and the other end presses against the right section cavity wall of the outer shell frame 1. After the pushing block 10 is driven to slide, it is connected to the right end of the adjusting frame 7 by pressing. The pushing adjusting frame 7 slides to the left in the right section cavity of the outer shell frame 1, and the first spring 9 is compressed and undergoes elastic deformation. Because a through groove is provided in the middle of the front shell wall of the outer shell frame 1, the shell cavity of the outer shell frame 1 and the shell cavity of the protective shell 101 are connected through the groove. Also, because an integrated shaft column is vertically provided on the front side of the left end of the horizontal frame of the adjusting frame 7, after the adjusting frame 7 is installed, the shaft column moves through the groove on the front shell wall of the outer shell frame 1 and extends into the shell cavity of the protective shell 101. When the adjusting frame 7 is driven to slide, the shaft column of the adjusting frame 7 slides along the groove on the front shell wall of the outer shell frame 1 in the shell cavity of the protective shell 101. Since the tensioning groove wheel 2 is fixedly connected to the center of the wheel, after the tensioning groove wheel 2 is installed, it is connected to the shaft of the adjusting frame 7 along with the bearing, and is set in a movable positioning state. The adjusting frame 7 is driven to slide to the left, and the tensioning groove wheel 2 forms a synchronous sliding structure, so that the tensioning groove wheel 2 slides to the left in the cavity of the protective shell 101. Since the tensioning groove wheel 2 is equipped with a wire feeding groove wheel 4 and a wire output groove wheel 5 above and below it respectively, and the wire feeding groove wheel 4 and the wire output groove wheel 5 are on the same vertical central axis, their specifications and dimensions are the same. The distance between the tensioning groove wheel 2 and the wire feeding groove wheel 4 is equal to the distance between the tensioning groove wheel 2 and the wire output groove wheel 5. That is, the tensioning groove wheel 2 is located at the midpoint of the gap between the wire feeding groove wheel 4 and the wire output groove wheel 5. Furthermore, since the specifications and dimensions of the grooves in the wire feeding groove wheel 4 and the wire output groove wheel 5 are the same as those of the grooves in the tensioning groove wheel 2, and the grooves in all three are adapted to fit the electrode wire, the grooves in the wire feeding groove wheel 4 and the wire output groove wheel 5 are the same as those in the grooves in the tensioning groove wheel 2. Located on the same vertical plane, and with the tensioning groove wheel 2, the feed groove wheel 4, and the output groove wheel 5 all connected to the electrode wire by a winding and engaging method, the electrode wire is wound and engaged from the right side of the feed groove wheel 4 to the left side of the tensioning groove wheel 2, and then wound and engaged from the left side of the tensioning groove wheel 2 to the right side of the output groove wheel 5. After the tensioning groove wheel 2 slides to the left for adjustment, the electrode wire is pushed by the tensioning groove wheel 2. The tensioning groove wheel 2, the feed groove wheel 4, and the output groove wheel 5 are arranged in an isosceles triangle, so that the tension generated after pushing is evenly distributed on both sides of the tensioning groove wheel 2, improving the stability of the wire tensioning. Thus, the tensioning operation of the electrode wire is automatically completed through the cooperation between the tensioning groove wheel 2, the feed groove wheel 4, and the output groove wheel 5.

[0023] Specifically, in this technical solution, the tensioning groove wheel 2 after sliding adjustment is automatically locked, according to... Figure 4 , Figure 5 and Figure 6 As shown, through the pushing and squeezing action of the pushing block 10 on the adjusting frame 7, the adjusting frame 7 drives the tension groove wheel 2 to perform a wide range of sliding adjustment, and freely adjust the included angle between the tension groove wheel 2 and the wire feeding groove wheel 4 and the wire output groove wheel 5, so as to meet different processing requirements and freely adjust the applicability of the electrode wire tension. Because the ratchet locking block 11 is arranged in a "T" shape, it is divided into two parts: a transverse block and a longitudinal block. The transverse block faces the rear and is vertically arranged in the middle of the longitudinal block. The end of the transverse block is the ratchet end. After the ratchet locking block 11 is installed, it is movably locked in the groove of the longitudinal frame in the adjusting frame 7. The ratchet end moves through the rear groove wall of the longitudinal frame in the adjusting frame 7 and extends outward. Through the "T" shape of the ratchet locking block 11, the ratchet locking block 11 is positioned in a movable state on the longitudinal frame in the adjusting frame 7. Furthermore, because the ratchet frame 13 is located on the right section of the shell cavity wall of the outer shell frame 1... Inside, the ratchet frame 13 is locked in place by the locking action of the U-shaped locking frame 30 on the linkage column 27. Since a through groove is provided on the rear wall of the right section of the outer shell frame 1, the ratchet end of the transverse block 11 moves through the groove on the right section of the outer shell frame 1 and extends into the right section of the outer shell frame 1. The ratchet end of the transverse block is connected to the ratchet frame 13. When the adjusting frame 7 is driven to slide to the left, the ratchet end of the ratchet lock block 11 slides along the ratchet in the ratchet frame 13, and the ratchet lock block 11 slides in conjunction with the rear end of the longitudinal frame in the adjusting frame 7. Because spring compartments are provided on both the upper and lower sides of the longitudinal block in the ratchet locking block 11, and a second spring 12 is installed at the sliding connection between the ratchet locking block 11 and the adjusting frame 7, the second spring 12 is symmetrically arranged about the horizontal central axis of the ratchet locking block 11. After installation, the second spring 12 is movably inserted into the spring compartment in the ratchet locking block 11, with one end pressing against the wall of the spring compartment in the ratchet locking block 11 and the other end pressing against the groove wall of the longitudinal frame in the adjusting frame 7. Furthermore, because the specifications and dimensions of the ratchet teeth in the ratchet rack 13 are compatible with the specifications and dimensions of the ratchet tooth ends in the ratchet locking block 11, when the ratchet tooth ends of the ratchet locking block 11 are pushed by the ratchet teeth in the ratchet rack 13, they are pushed against the rear of the longitudinal frame in the adjusting frame 7. The end contracts and slides, causing the second spring 12 to undergo elastic deformation under compression. When the ratchet end of the ratchet locking block 11 loses the push of the ratchet in the ratchet frame 13, the elastic deformation of the second spring 12 resets, causing the ratchet locking block 11 to extend and slide at the rear end of the longitudinal frame in the adjusting frame 7, and the ratchet end of the ratchet locking block 11 to engage between the two ratchets in the ratchet frame 13. After the adjusting frame 7 is driven to slide to the left, the engagement between the ratchet locking block 11 and the ratchet frame 13, along with the elastic deformation reset of the first spring 9, performs the locking process of the adjusting frame 7, that is, completes the automatic locking operation after the sliding adjustment of the tensioning groove wheel 2, ensuring that the tensioning groove wheel 2 can form a stable tension force on the electrode wire.

[0024] Specifically, in this technical solution, the monitoring component 6 is slidably mounted on the left section of the outer shell 1. It is driven by the adjusting component 3, and the monitoring component 6 is used to monitor and measure the tension force in real time during electrode wire tension adjustment. Figure 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. 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.

[0025] 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. Since the end of the limiting claw 23 closest to 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. The upper and lower limiting claws 23 are arranged in opposite directions. Since the inward end of the limiting claw 23 is provided with an integrated gear part, and the rack column 24 is provided with racks on both the upper and lower sides, the racks on the upper and lower sides correspond to the gear parts of the upper and lower limiting claws 23 respectively. The gear part in the limiting claw 23 is connected to the rack column 24 by meshing. After 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 in the limiting claw 23. Since the inner end of the limiting claw 23 is connected to the shaft column through the bearing to assist rotation, after the limiting claw 23 is installed, the inner end of it is movably locked in the cavity of the round tube shell 22, and the two ends of the shaft column are respectively inserted and fixedly connected to the two sides of the cavity wall of the round tube shell 22 by bolts. When the limiting claw 23 is driven, it flips and unfolds on the round tube shell 22, and the upper and lower limiting claws 23 flip and unfold in opposite directions. Since the square column 17 is installed and movably sleeved on the output rod of the electric telescopic rod 8, the center of the square column 17 and the center of the output rod of the electric telescopic rod 8 are on the same horizontal central axis. When the electric telescopic rod 8 is started to retract, the pushing block 10 slides to the right in the right section of the outer shell 1. After the pushing block 10 slides to the right, it loses its pressure on the adjusting frame 7. At this time, through the engagement between the ratchet locking block 11 and the ratchet frame 13, and with the elastic deformation and reset of the first spring 9, the adjusting frame 7 is locked. Even if the tensioning groove wheel 2 is locked in the state after sliding adjustment, when the electric telescopic rod 8 retracts, the output rod of the electric telescopic rod 8 slides in the transverse frame of the adjusting frame 7, and the output rod of the electric telescopic rod 8 slides to the right on the square column 17. Since the limiting component 21 and the output rod of the electric telescopic rod 8 are on the same horizontal central axis, they form a synchronous motion structure. After the round tube shell 22 is installed, it is inserted and fixedly connected to the left end of the output rod of the electric telescopic rod 8 with bolts. After the output rod of the electric telescopic rod 8 slides to the right on the square column 17, the extended limiting claw 23 is connected to the square column 17 by pressing and pushing. The electric telescopic rod 8 continues to retract and operate. The outward end of the limiting claw 23 presses against the left side wall of the square column 17 and pushes the square column 17 to move synchronously. Since the square column 17 is installed and movably locked in the left section of the outer shell 1, the square column 17 is positioned in a movable state within the outer shell 1 and can only slide linearly. Since the square column 17 has a spring compartment with the same center, a third spring 18 is installed at the sliding connection between the square column 17 and the outer shell 1. After the third spring 18 is installed, it is movably inserted into the spring compartment of the square column 17. It is connected to the output rod of the electric telescopic rod 8 by a movable sleeve. One end of it presses against the wall of the spring compartment in the square column 17, and the other end presses against the wall of the left section of the outer shell 1. After being pushed, the square column 17 slides to the right in the left section of the outer shell 1, and the third spring 18 is compressed and undergoes elastic deformation. Since the U-shaped frame 14 is composed of a longitudinal frame and two transverse frames, with the two transverse frames respectively set vertically on the upper and lower sides of the longitudinal frame, after the U-shaped frame 14 is installed, the longitudinal frame fits against the rear shell wall of the outer casing 1, and the upper and lower transverse frames are respectively movably locked on the upper and lower shell walls of the outer casing 1, so that the U-shaped frame 14 is movably positioned on the outer casing 1. Since the rear shell wall of the left section of the outer casing 1 has a through groove, and the longitudinal frame of the U-shaped frame 14 has an integrated protrusion on the front side, after the U-shaped frame 14 is installed, the protrusion moves through the groove on the rear shell wall of the outer casing 1, and the protrusion is locked and fixed to the square column 17 by bolts. 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 section shell wall of the outer casing 1, so that the monitoring component 6 makes a horizontal linear sliding movement toward the electrode wire. Since the monitoring component 6 includes a U-shaped frame 14, a first detection claw 15 located on the upper side of the U-shaped frame 14, and a second detection claw 16 located on the lower side of the U-shaped frame 14, both the right ends of the first detection claw 15 and the right ends of the second detection claw 16 are rotatably connected to grooved wheels. The grooved wheel in the first detection claw 15 corresponds to the upper part of the wire feeding grooved wheel 4, and the grooves in both are on the same vertical plane. The grooved wheel in the second detection claw 16 corresponds to the lower part of the wire exit grooved wheel 5, and the grooves in both are also on the same vertical plane. Furthermore, since the first detection claw 15... Both the grooved wheel in the first detection claw 15 and the grooved wheel in the second detection claw 16 are connected to the electrode wire by a snap-fit ​​method. When the U-shaped frame 14 is driven to slide to the right, the grooved wheel in the first detection claw 15 snaps against the entry section of the electrode wire for monitoring the tension of the entry section of the electrode wire, and the grooved wheel in the second detection claw 16 snaps against the exit section of the electrode wire for monitoring the tension of the exit section of the electrode wire. After the U-shaped frame 14 is driven to slide to the right, the entry section and the exit section of the electrode wire push the first detection claw 15 and the second detection claw 16 to move respectively. Since the upper and lower horizontal frames of the U-shaped frame 14 are equipped with integrated connecting seats, the left end of the first detection claw 15 is connected to a shaft column through a bearing for assisted rotation. After the first detection claw 15 is installed, its shaft column is inserted and fixedly connected to the connecting seat of the upper horizontal frame of the U-shaped frame 14 with bolts. The structure of the second detection claw 16 is the same as that of the first detection claw 15, and the two are installed in the same way. After the second detection claw 16 is installed, its shaft column is inserted and fixedly connected to the connecting seat of the lower horizontal frame of the U-shaped frame 14 with bolts. Since the first detection claw 15 and the second detection claw 16 are set in opposite directions, they are combined to form an "eight" shaped structure. When the first detection claw 15 is pushed, it can rotate and flip on the upper side of the U-shaped frame 14 through its shaft column. When the second detection claw 16 is pushed, it can rotate and flip on the lower side of the U-shaped frame 14 through its shaft column. This makes the flipping direction of the first detection claw 15 and the flipping direction of the second detection claw 16 opposite. Because the left end of the first detection claw 15 is provided with an integrated sliding plate, which has a through-shaped groove, and the sliding plate of the second detection claw 16 also has a through-shaped groove, and because both the upper and lower ends of the linkage frame 19 are fixedly connected with pins, when the first detection claw 15 is connected to the linkage frame 19, the sliding plate of the first detection claw 15 is movably inserted into the upper cavity of the linkage frame 19, and the upper pin of the linkage frame 19 moves through the sliding plate of the first detection claw 15. When the second detection claw 16 is connected to the linkage frame 19, the deflector portion of the second detection claw 16 is movably inserted into the lower end cavity of the linkage frame 19, and the lower end pin of the linkage frame 19 is movably inserted through the slide groove of the deflector portion of the second detection claw 16. After the first detection claw 15 and the second detection claw 16 rotate synchronously in opposite directions, the deflector portions of the first detection claw 15 and the second detection claw 16 slide at the upper and lower ends of the linkage frame 19 respectively, pulling the linkage frame 19 to move. Since the left end of the longitudinal frame in the U-shaped frame 14 is bent, the tension sensor 20 is placed on the same horizontal central axis as the U-shaped frame 14. Its left end is fixedly installed on the bent end of the longitudinal frame in the U-shaped frame 14 by bolts, and its right end is fixedly connected to the linkage frame 19 by bolts. The tension displacement of the linkage frame 19 is detected by the tension sensor 20, that is, the tension of the electrode wire is monitored. Conversely, when the electric telescopic rod 8 extends and operates, it releases the pushing of the limit component 21 on the square column 17. The elastic deformation of the third spring 18 resets the square column 17, causing the U-shaped frame 14 to slide to the left. The grooved wheel in the first detection claw 15 and the grooved wheel in the second detection claw 16 separate from the entry and exit sections of the electrode wire, respectively.

[0026] Specifically, in this technical solution, the electrode wire is placed within the tensioning wire adjustment structure, according to... Figure 1 , Figure 2 and Figure 3 As shown, the protective shell 101 is an integrated structure vertically installed in the middle of the front shell wall of the outer shell frame 1. Since both the upper and lower ends of the shell cavity in the protective shell 101 are open, the upper opening of the shell cavity is the inlet and the lower opening of the shell cavity is the outlet. When the electrode wire is installed, it enters the shell cavity of the protective shell 101 through the inlet and winds around and engages with the right side of the wire feed groove wheel 4, the left side of the tension groove wheel 2 and the right side of the wire output groove wheel 5 in sequence. After the electrode wire passes through the shell cavity of the protective shell 101, it passes through the outlet of the protective shell 101 to the outside. Because an integrated shaft column is vertically installed at the upper end of the cavity wall of the protective shell 101, a bearing is fixedly engaged at the center of the feed groove wheel 4. After the feed groove wheel 4 is installed, it is sleeved on the upper shaft column of the protective shell 101 along with the bearing, and is set in a movable positioning state. The feed groove wheel 4 forms a rotating structure on the upper shaft column of the protective shell 101. Also, because an integrated shaft column is vertically installed at the lower end of the cavity wall of the protective shell 101, a bearing is fixedly engaged at the center of the output groove wheel 5. After the output groove wheel 5 is installed, it is sleeved on the lower shaft column of the protective shell 101 along with the bearing, and is set in a movable positioning state. The output groove wheel 5 forms a rotating structure on the lower shaft column of the protective shell 101. Furthermore, because the tension groove wheel 2 forms a rotating structure on the shaft column of the adjusting frame 7, the rotating tension groove wheel 2, feed groove wheel 4, and output groove wheel 5 assist the electrode wire to operate smoothly.

[0027] Example 2: Based on Example 1, please refer to the following example of the present invention. Figures 11-13 The technical solution shown is that in existing electrode wire tensioning mechanisms, the tensioning wheel, the lead-out wheel, and the lead-in wheel are usually arranged in a triangle. The tensioning wheel works in conjunction with the lead-out wheel and the lead-in wheel to achieve tensioning and guiding of the electrode wire. However, due to the staggered arrangement of the tensioning wheel, lead-out wheel, and lead-in wheel, the electrode wire is difficult to wind and pass through them sequentially, making the installation operation cumbersome. The push block 10 first... The U-shaped locking frame 30 is docked, releasing the locking of the U-shaped locking frame 30 to the linkage column 27. The pushing block 10 then docks with the L-shaped frame 28. Through the sliding cooperation between the pin 2701 and the inclined groove 1301, the locking connection between the ratchet frame 13 and the ratchet locking block 11 is released. The elastic deformation of the first spring 9 is used to reset the locked adjusting frame 7, which drives the tension groove wheel 2 to reset and slide, separating it from the wire feed groove wheel 4 and the wire output groove wheel 5, thus facilitating the insertion of the auxiliary electrode wire.

[0028] Specifically, in this technical solution, when performing convenient placement of the electrode wire, according to Figure 11 , Figure 12 and Figure 13 As shown, when the telescopic electromagnet 25 is activated, it drives the rack column 24 to slide to the left within the cavity of the round tube shell 22. Through the meshing action between the rack column 24 and the gear part of the limiting pawl 23, the limiting pawl 23 is driven to flip and close on the round tube shell 22. After the limiting pawl 23 flips and closes, it is stored in the cavity of the round tube shell 22 without affecting the insertion of the round tube shell 22 and the square column 17. Since the diameter of the round tube shell 22 is the same as the diameter of the output rod in the electric telescopic rod 8, when the electric telescopic rod 8 is activated to retract, the round tube shell 22 can follow the output rod in the electric telescopic rod 8 to insert into the square column 17. After the electric telescopic rod 8 retracts, the pushing block 10 slides to the right within the right section of the outer shell frame 1. Because the rear end of the right side wall of the push block 10 has an inclined side wall, and because a U-shaped locking frame 30 for locking the linkage column 27 is provided on the left side of the L-shaped frame 28, the U-shaped locking frame 30 is composed of a longitudinal frame and two transverse frames. The two transverse frames are respectively arranged vertically on the upper and lower sides of the longitudinal frame, and the ends of the transverse frames are hemispherical. After the U-shaped locking frame 30 is installed, it is movably locked in the right section of the shell cavity wall of the outer shell frame 1, and both transverse frames movably pass through the outer shell frame 1. The right section of the shell cavity wall extends into the right section of the shell cavity of the outer shell frame 1, and is set in accordance with the inclined side wall of the push block 10. The push block 10 slides to the right to reset and first docks with the U-shaped lock frame 30. The inclined side wall of the push block 10 is connected to the hemispherical end of the transverse frame in the U-shaped lock frame 30 by pressing, so that the hemispherical end of the transverse frame in the U-shaped lock frame 30 slides along the inclined side wall of the push block 10 to the rear side wall of the push block 10, and the U-shaped lock frame 30 is pushed into the right section of the shell cavity wall of the outer shell frame 1 to retract and slide. Since the two transverse frames of the U-shaped lock frame 30 are equipped with integrated limiting plates, and the sliding connection between the U-shaped lock frame 30 and the outer shell frame 1 is equipped with a sixth spring 31, the sixth spring 31 is symmetrically arranged about the horizontal central axis of the U-shaped lock frame 30. The two sixth springs 31 are respectively placed on the two transverse frames of the U-shaped lock frame 30. After the sixth spring 31 is installed, it is movably sleeved on the transverse frame of the U-shaped lock frame 30. One end of the sixth spring 31 presses against the limiting plate of the transverse frame of the U-shaped lock frame 30, and the other end presses against the right section of the shell cavity wall of the outer shell frame 1. After the U-shaped lock frame 30 contracts and slides, the longitudinal frame of the U-shaped lock frame 30 loses its locking connection with the linkage column 27, releases the locking of the linkage column 27, and causes the sixth spring 31 to undergo elastic deformation under compression. Since the length of the pushing block 10 is greater than the distance between the U-shaped locking frame 30 and the sliding L-shaped frame 28, the U-shaped locking frame 30 is pushed to release the locking of the linkage column 27. When the pushing block 10 continues to slide to the right and docks with the L-shaped frame 28, the hemispherical end of the transverse frame in the U-shaped locking frame 30 slides along the rear side wall of the pushing block 10, keeping the U-shaped locking frame 30 in the unlocked state. The L-shaped frame 28 is divided into two parts: a transverse frame and a longitudinal frame. The longitudinal frame faces forward and is vertically positioned at the left end of the transverse frame. After installation, the L-shaped frame 28 is movably locked into the right section of the outer shell cavity wall of the outer shell frame 1. The longitudinal frame extends through the right section of the outer shell cavity wall of the outer shell frame 1 and corresponds to the right side wall of the push block 10. Furthermore, a fifth spring 29 is installed at the sliding connection between the L-shaped frame 28 and the outer shell frame 1. After the fifth spring 29 is installed... The push block 10 is inserted into the right section of the shell cavity wall of the outer shell frame 1. One end of the push block 10 presses against the transverse frame of the L-shaped frame 28, and the other end presses against the right section of the shell cavity wall of the outer shell frame 1. The push block 10 continuously slides to the right to reset and then docks with the L-shaped frame 28. The right side wall of the push block 10 is connected to the longitudinal frame of the L-shaped frame 28 by pressing. The L-shaped frame 28 slides to the right in the right section of the shell cavity wall of the outer shell frame 1 by the push block 10, and the fifth spring 29 is compressed and undergoes elastic deformation. Since the ratchet frame 13 has integrated limiting plates vertically installed at both the upper and lower ends on the side away from the ratchet locking block 11, after the linkage column 27 is installed, its right section is movably inserted into the right section of the shell cavity wall of the outer shell frame 1, and its left section is movably inserted into the gap between the upper and lower limiting plates of the ratchet frame 13. Also, after the linkage column 27 is installed, its right end is inserted and fixedly connected to the transverse frame of the L-shaped frame 28 by bolts. 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 section of the shell cavity wall of the outer shell frame 1, and the linkage column 27 forms a sliding structure between the two limiting plates in the ratchet frame 13. Since the inclined grooves 1301 are evenly spaced and connected in a through state on the limiting plate of the ratchet frame 13, the inclined grooves 1301 on the upper limiting plate and the inclined grooves 1301 on the lower limiting plate correspond to each other. Since the pins 2701 are evenly spaced on the linkage column 27, they are inserted and fixed to the linkage column 27 by bolts after installation, and both their upper and lower ends extend outward. Each pin 2701 corresponds to each inclined groove 1301. Since the pins 2701 are movably inserted into the inclined grooves 1301 on the upper and lower limiting plates respectively after installation, the linkage column 27 is driven to slide to the right, causing the pins 2701 to slide along the inclined grooves 1301. Because the ratchet rack 13 is movably locked inside the right section of the outer shell cavity wall of the outer shell frame 1 after installation, it is positioned in a movable state. Furthermore, because the ratchet rack 13 has spring compartments evenly spaced on the side opposite to the ratchet locking block 11, and these spring compartments are symmetrically arranged about the horizontal central axis of the ratchet rack 13, a fourth spring 26 is installed at the sliding connection between the ratchet rack 13 and the outer shell frame 1. The fourth spring 26 is evenly spaced on the ratchet rack 13 and is symmetrically arranged about the horizontal central axis of the ratchet rack 13. After the spring 26 is installed, it is movably inserted into the spring compartment of the ratchet frame 13. One end of the spring 26 presses against the spring compartment wall of the ratchet frame 13, and the other end presses against the right section cavity wall of the outer shell frame 1. Through the sliding engagement between the pin 2701 and the inclined groove 1301, the ratchet frame 13 slides in the right section cavity wall of the outer shell frame 1, and the fourth spring 26 is compressed and undergoes elastic deformation. After the ratchet frame 13 slides, it releases the engagement connection with the ratchet locking block 11, that is, it releases the lock on the adjusting frame 7. When the adjusting frame 7 is unlocked, the elastic deformation of the first spring 9 is used to reset the adjusting frame 7, causing the tensioning groove wheel 2 to slide to the right within the cavity of the protective shell 101, so that the tensioning groove wheel 2 separates from the wire feeding groove wheel 4 and the wire output groove wheel 5. At this time, the electrode wire can be easily inserted through the protective shell 101 and can be easily wound and locked onto the tensioning groove wheel 2, the wire feeding groove wheel 4 and the wire output groove wheel 5, thus completing the convenient placement of the electrode wire. 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.
