Description

Technical Field

[0001] This invention relates to the field of steel strip processing equipment technology, and in particular to a multifunctional tooling fixture that can be quickly changed on a steel strip processing line. Background Technology

[0002] In the existing technology, steel strip processing lines are production lines used in the metal sheet processing industry to continuously carry out multiple processes such as conveying, straightening, leveling, and cutting of steel strips. They are widely used in automobile manufacturing, home appliance production, building materials processing, and machinery manufacturing. During the processing, the steel strip needs to be positioned and clamped by tooling fixtures to ensure the positional accuracy and stability of the steel strip during conveying and processing. The tooling fixtures apply clamping force to the steel strip through clamping components to prevent the steel strip from shifting or shaking during processing. The tooling fixtures commonly used on steel strip processing lines are fixedly installed on the equipment by bolt connection or welding to position and clamp the steel strip.

[0003] However, the above technical solution still has the following problems due to the cumbersome disassembly and installation process of the tooling fixtures on the steel strip processing line when changing the specifications or models of the steel strip: Traditional tooling fixtures are fixed to equipment with multiple bolts. When it is necessary to change the fixture model to accommodate steel strips of different widths or thicknesses, each bolt must be disassembled and installed one by one. This operation is time-consuming and requires special tools, which seriously affects the changeover efficiency of the production line. At the same time, the clamping force adjustment of traditional fixtures depends on manual operation and cannot automatically adjust the clamping force according to the thickness of the steel strip. Excessive clamping force will cause indentations on the surface of the steel strip, while insufficient clamping force will not be able to effectively position the steel strip. Moreover, traditional fixtures lack quick locking and releasing structures during installation. The installation and disassembly of fixtures require multiple people to operate, which increases labor costs and operational difficulty. Summary of the Invention

[0004] Based on the existing technical issues, the disassembly and installation of tooling fixtures on steel strip processing lines are cumbersome when changing steel strip specifications or models. Traditional tooling fixtures are fixed to the equipment with multiple bolts. When it is necessary to change the fixture model to adapt to steel strips of different widths or thicknesses, it is necessary to disassemble and install each bolt one by one, which is time-consuming and requires special tools, seriously affecting the changeover efficiency of the production line. At the same time, the clamping force adjustment of traditional fixtures depends on manual operation and cannot automatically adjust the clamping force according to the thickness of the steel strip. Excessive clamping force will cause indentations on the surface of the steel strip, while insufficient clamping force will not be able to effectively position the steel strip. Moreover, traditional fixtures lack a quick locking and releasing structure during installation. The installation and disassembly of fixtures require multiple people to cooperate, which increases labor costs and operational difficulty. To address these technical problems, this invention proposes a multi-functional tooling fixture for steel strip processing lines that can be quickly changed.

[0005] This invention proposes a multi-functional tooling fixture for quick-change on a steel strip processing line, comprising a connecting bracket and an insertion bracket. The multi-functional tooling fixture also includes: The mounting and fixing mechanism is installed on the connecting bracket; A clamping and positioning mechanism is mounted on the insertion frame.

[0006] Using the above mechanism: by inserting the insertion frame into the connecting bracket, the electric push rod pushes the control plate, which in turn pulls the hollow column downwards through the insertion frame. At the same time, the limiting frame engages with the limiting groove at the bottom of the insertion frame, enabling the insertion frame to be quickly installed and fixed. The motor drives the rotating plate to rotate, pushing the control clamp to rise and engage with the support clamp to complete the clamping and positioning of the steel strip. When it is necessary to change the clamp model, the sliding frame can be moved by pulling the first pull ring to remove the restriction on the limiting frame, allowing the insertion frame to be quickly pulled out for replacement.

[0007] As a preferred embodiment of the present invention, the mounting and fixing mechanism includes an electric push rod, a control plate, a pull plate, a hollow column, a limiting frame, a first spring, a sliding frame, a first pull ring, and a second spring. The electric push rod is fixedly connected to the top of the connecting bracket, the control plate is slidably connected to the top of the connecting bracket, and the right side of the control plate is fixedly connected to the output end of the electric push rod. The pull plate is rotatably connected to the front side of the control plate. The hollow column is slidably connected inside the connecting bracket, and the front side of the hollow column is rotatably connected to the top of the pull plate. The limiting frame is disposed inside the hollow column, the first spring is fixed to the top of the limiting frame, and one end of the first spring is fixedly connected to the inner wall of the top of the hollow column. A limiting groove is provided at the bottom of the insertion frame, and the limiting frame is movably connected to the limiting groove. The sliding frame is slidably connected to the bottom of the connecting bracket, the first pull ring is fixed to the bottom of the sliding frame, the second spring is fixed to the right side of the sliding frame, and one end of the second spring is fixedly connected to the left side of the connecting bracket.

[0008] Furthermore, when the insertion frame needs to be installed, it is inserted into the connecting bracket. At this time, the control system activates the electric actuator, which extends to the left, pushing the control plate fixedly connected to its output end to slide to the left along the top of the connecting bracket. As the control plate slides to the left, it causes the pull plate rotatably connected to its front side to move to the left. The pull plate pulls the hollow column rotatably connected to its top to slide downward along the first guide hole in the connecting bracket. As the hollow column slides downward, it causes the internal limiting frame to descend synchronously and penetrate the insertion frame. The operator pulls the first pull ring to make the sliding frame slide to the left along the bottom of the connecting bracket. When the sliding frame slides to the left... The second spring, located between the right side of the insert frame and the left side of the connecting bracket, stores elastic potential energy. At this time, the limiting frame is rotated so that the snap-fit ​​protrusion on the top of the limiting frame aligns with the limiting groove at the bottom of the insert frame. The first spring releases its elastic potential energy, pulling the limiting frame vertically upward along the second guide hole inside the hollow column, causing the snap-fit ​​protrusion on the top of the limiting frame to engage in the limiting groove, thus completing the snap-fit ​​engagement. Then, the first pull ring is released, and the second spring releases its stored elastic potential energy, pushing the sliding frame to slide back to the right. The right end face of the sliding frame contacts the bottom of the limiting frame, limiting the limiting frame and preventing it from exiting the limiting groove, thereby completing the quick installation and fixation of the insert frame and the connecting bracket.

[0009] As a preferred embodiment of the present invention, the clamping and positioning mechanism includes a slide rail, a control clamp, an extension frame, a third spring, a support clamp, anti-slip pads, a motor, a rotating plate, and a second pull ring. The slide rail is fixed to the right side of the insertion frame, the control clamp is slidably connected inside the slide rail, the extension frame is fixed to the front side of the control clamp, and the front side of the extension frame passes through the slide rail, the third spring is fixed to the bottom of the extension frame, and one end of the third spring is fixedly connected to the front side of the insertion frame, the support clamp is fixed inside the slide rail, two anti-slip pads are respectively set on the side of the control clamp and the support clamp that are close to each other, the motor is fixed to the left side of the insertion frame, and the output shaft of the motor passes through the insertion frame, the rotating plate is fixed to the right end of the motor output shaft, and the second pull ring is fixed to the top of the control clamp.

[0010] Furthermore, after the insertion frame is installed, the operator pulls the control clamp upward along the guide groove of the slide rail using the second pull ring, creating sufficient space between the control clamp and the support clamp. The steel strip is then placed in the clamping area between the control clamp and the support clamp. Subsequently, the control system starts the motor, and the output shaft of the motor rotates, causing the rotating plate fixed at its right end to rotate synchronously. During the rotation, the arc-shaped extrusion surface at the top of the rotating plate contacts the top end face of the control clamp and pushes the control clamp downward along the slide rail. As the control clamp descends, it causes the extension frame fixed at its front to descend synchronously. When the extension frame descends, it compresses the third spring between its bottom and the front side of the insertion frame to store elastic potential energy. At the same time, the control clamp moves closer to the support clamp, and the anti-slip pads at the bottom of the control clamp and the top of the support clamp approach each other, applying a uniform clamping force to both sides of the steel strip, thereby completing the clamping and positioning of the steel strip.

[0011] As a preferred embodiment of the present invention, the top of the connecting bracket is provided with a sliding groove, the bottom of the control plate is provided with a sliding protrusion, the sliding protrusion is slidably connected to the inner wall of the sliding groove, the connecting bracket is provided with a first guide hole, and the outer wall of the hollow column is slidably connected to the inner wall of the first guide hole.

[0012] Furthermore, the sliding groove and sliding protrusion cooperate to guide and limit the sliding of the control plate, and the first guide hole guides the vertical sliding of the hollow column, ensuring that the hollow column rises and falls smoothly in the vertical direction.

[0013] As a preferred embodiment of the present invention, a second guide hole is provided inside the hollow column, the outer wall of the limiting frame is slidably connected to the inner wall of the second guide hole, a snap-fit ​​protrusion is provided on the top of the limiting frame, the snap-fit ​​protrusion is movably snapped into the inner wall of the limiting groove, and the first spring is a tension spring.

[0014] Furthermore, the second guide hole guides the vertical sliding of the limiting frame, and the engaging protrusion engages with the limiting groove to achieve rapid locking of the insertion frame. The first spring is stretched and stores elastic potential energy when the limiting frame descends, and releases the elastic potential energy when the limiting frame aligns with the limiting groove to pull the limiting frame upward to complete the engagement.

[0015] As a preferred embodiment of the present invention, the slide rail is provided with a guide groove, the outer wall of the control clamp is slidably connected to the inner wall of the guide groove, a through groove is provided on the front side of the slide rail, the front end of the extension frame passes through the through groove and extends to the outside of the slide rail, and the No. 3 spring is a compression spring.

[0016] Furthermore, the guide groove guides the vertical sliding of the control fixture, and the extension frame extends through the through groove to the outside of the slide rail, which facilitates the application of elastic force by the No. 3 spring to the extension frame. The No. 3 spring is compressed and stores elastic potential energy when the control fixture descends, and releases elastic potential energy when the motor reverses to push the control fixture to rise and reset.

[0017] As a preferred embodiment of the present invention, a rotation gap is provided between the output shaft of the motor and the left side wall of the insertion frame, and an arc-shaped extrusion surface is provided on the top of the rotating plate. The arc-shaped extrusion surface is in active contact with the top end face of the control fixture, and both anti-slip pads are rubber pads.

[0018] Furthermore, the rotation clearance ensures that the motor output shaft does not interfere with the left side wall of the insertion frame during rotation. The arc-shaped extrusion surface makes smooth contact with the top end face of the control fixture during the rotation of the rotating plate and pushes the control fixture to descend smoothly. The rubber pad protects the surface of the steel strip and prevents indentations during clamping.

[0019] As a preferred embodiment of the present invention, two anti-slip pads are respectively fixedly bonded to the bottom end face of the control clamp and the top end face of the support clamp, and anti-slip textures are provided on the side of the two anti-slip pads that are close to each other.

[0020] Furthermore, the anti-slip texture increases the friction between the anti-slip pad and the steel strip surface, preventing the steel strip from slipping during clamping and improving the stability and reliability of clamping.

[0021] The beneficial effects of this invention are: 1. After the electric actuator pushes the control board to the left, the control board can drive the hollow column to descend through the insertion frame via the pull plate. At the same time, the limiting frame and the limiting groove at the bottom of the insertion frame engage to achieve quick installation and fixation of the insertion frame. When it is necessary to change the fixture model, the sliding frame can be moved by pulling the No. 1 pull ring to remove the restriction on the limiting frame, and the insertion frame can be quickly pulled out for replacement, achieving the effect of quick model change. 2. After the motor drives the rotating plate to rotate, the rotating plate can push the control fixture to rise and cooperate with the support fixture to complete the clamping and positioning of the steel strip. The clamping force can be adjusted by controlling the rotation angle of the motor to adapt to the clamping requirements of steel strips of different thicknesses. 3. After the control fixture descends and drives the extension frame to compress the No. 3 spring, when the motor works in the reverse direction, the No. 3 spring releases its elastic potential energy to push the control fixture to rise and reset, realizing the automatic opening of the clamping mechanism, which facilitates the insertion and removal of the steel strip. 4. During the descent of the limiting frame, spring number one is stretched and stores elastic potential energy. When the limiting frame is aligned with the limiting slot, spring number one releases elastic potential energy to pull the limiting frame up automatically to complete the locking, thus achieving automatic locking during the installation process.

[0022] In this invention: by inserting the insertion frame into the connecting bracket, the electric push rod pushes the control plate, which in turn pulls the hollow column downwards through the insertion frame. At the same time, the limiting frame engages with the limiting groove at the bottom of the insertion frame to achieve quick installation. The rotating plate driven by the motor rotates to push the control clamp upwards and engages with the support clamp to complete the clamping and positioning of the steel strip. When it is necessary to change the clamp model, pulling the first pull ring can remove the restriction on the limiting frame and quickly pull out the insertion frame for replacement, achieving the effect of quick model change and convenient use.

Detailed Implementation

[0025] The present invention will be further explained below with reference to specific embodiments. Example

[0026] refer to Figure 1-5 This embodiment proposes a multi-functional tooling fixture for quick changeover on a steel strip processing line, including a connecting bracket 1 and an insertion bracket 2. The connecting bracket 1 is fixedly installed on the equipment frame of the steel strip processing line, and the insertion bracket 2 is detachably inserted into the connecting bracket 1. The multi-functional tooling fixture also includes: The mounting and fixing mechanism is installed on the connecting bracket 1; A clamping and positioning mechanism is installed on the insertion frame 2.

[0027] Using the above mechanism: by inserting the insertion frame 2 into the connecting bracket 1, the electric push rod 3 pushes the control plate 4 to move to the left. The control plate 4 drives the hollow column 6 to descend through the insertion frame 2 via the pull plate 5. At the same time, the limiting frame 7 engages with the limiting groove at the bottom of the insertion frame 2 to achieve quick installation and fixation of the insertion frame 2. The motor 18 drives the rotating plate 19 to rotate and push the control clamp 13 to descend and engage with the support clamp 16 to complete the clamping and positioning of the steel strip. When it is necessary to change the clamp model, the sliding frame 9 is moved by pulling the first pull ring 10 to remove the restriction on the limiting frame 7, and the insertion frame 2 can be quickly pulled out for replacement.

[0028] In this embodiment, the mounting and fixing mechanism includes an electric push rod 3, a control plate 4, a pull plate 5, a hollow column 6, a limiting frame 7, a first spring 8, a sliding frame 9, a first pull ring 10, and a second spring 11. The electric push rod 3 is fixedly connected to the top of the connecting bracket 1 by bolts. The control plate 4 is slidably connected to the top of the connecting bracket 1, and the right end face of the control plate 4 is fixedly connected to the output end of the electric push rod 3 by threads. When the electric push rod 3 extends or retracts, it can push the control plate 4 to slide left and right along the top of the connecting bracket 1. The rear end of the pull plate 5 is rotatably connected to the front end face of the control plate 4 through a rotating shaft. The hollow column 6 is a vertically arranged cylindrical hollow tube. The hollow column 6 is slidably connected in the first guide hole provided in the connecting bracket 1, and the front end face of the hollow column 6 is connected to the pull plate 5. The top end of the frame is rotatably connected via a pivot. The limiting frame 7 is vertically installed inside the hollow column 6. The outer wall of the limiting frame 7 is slidably connected to the inner wall of the second guide hole provided inside the hollow column 6. The first spring 8 is a tension spring. The bottom end of the first spring 8 is fixedly connected to the top end face of the limiting frame 7, and the top end of the first spring 8 is fixedly connected to the top inner wall of the hollow column 6. The bottom of the insertion frame 2 is provided with a limiting groove. The snap-fit ​​protrusion on the top of the limiting frame 7 is movably snapped into the inner wall of the limiting groove. The sliding frame 9 is slidably connected to the bottom of the connecting bracket 1. The first pull ring 10 is fixedly connected to the center of the bottom end face of the sliding frame 9. The second spring 11 is a compression spring. The left end of the second spring 11 is fixedly connected to the right end face of the sliding frame 9, and the right end of the second spring 11 is connected to the connecting bracket 1. The left end face of the connecting bracket 1 is fixedly connected. When the insertion bracket 2 needs to be installed, the insertion bracket 2 is inserted into the connecting bracket 1 horizontally. At this time, the control system starts the electric push rod 3. The output end of the electric push rod 3 extends to the left, pushing the control plate 4, which is fixedly connected to its output end, to slide smoothly to the left along the sliding groove at the top of the connecting bracket 1. When the control plate 4 slides to the left, it drives the pull plate 5, which is rotatably connected to its front side via a rotating shaft, to move to the left. The pull plate 5 pulls the hollow column 6, which is rotatably connected to its top via a rotating shaft, to slide vertically downward along the first guide hole in the connecting bracket 1. When the hollow column 6 slides downward, it drives the internal limiting frame 7 to descend synchronously and pass through the insertion bracket 2. The operator pulls the first pull ring 10 to make the sliding frame 9 slide to the left along the bottom of the connecting bracket 1. When the frame 9 slides to the left, it compresses the second spring 11 between its right side and the left side of the connecting bracket 1 to store elastic potential energy. At this time, the limiting frame 7 is rotated so that the snap-fit ​​protrusion on the top of the limiting frame 7 is aligned with the limiting groove at the bottom of the insertion frame 2. The first spring 8 releases the stored elastic potential energy and pulls the limiting frame 7 vertically upward along the second guide hole in the hollow column 6, so that the snap-fit ​​protrusion on the top of the limiting frame 7 is engaged in the limiting groove, completing the snap-fit ​​engagement. Then, the first pull ring 10 is released, and the second spring 11 releases the stored elastic potential energy to push the sliding frame 9 to slide back to the right. The right end face of the sliding frame 9 contacts the bottom of the limiting frame 7, limiting the limiting frame 7 and preventing it from exiting the limiting groove due to vibration during use, thereby completing the quick installation and fixation of the insertion frame 2 and the connecting bracket 1.

[0029] In this embodiment, the clamping and positioning mechanism includes a slide rail 12, a control clamp 13, an extension frame 14, a third spring 15, a support clamp 16, an anti-slip pad 17, a motor 18, a rotating plate 19, and a second pull ring 20. The slide rail 12 is a vertically arranged rectangular slide rail, and its left end face is fixedly connected to the right end face of the insertion frame 2 by bolts. The control clamp 13 is an L-shaped clamping block, which is slidably connected in the guide groove provided in the slide rail 12. The control clamp 13 can slide up and down along the vertical direction of the slide rail 12. The extension frame 14 is a horizontally arranged L-shaped connecting rod, and its rear end is fixedly connected to the front end face of the control clamp 13. The front end of the extension frame 14 passes through the through groove opened on the front side of the slide rail 12 and extends to the outside of the slide rail 12. The third spring 15 is a compression spring. The top end of the third spring 15 is fixedly connected to the bottom end face of the extension frame 14, and the bottom end of the third spring 15 is fixedly connected to the front end face of the insertion frame 2. The support clamp 16 is an L-shaped fixed clamping block. The left end face of the support clamp 16 is fixedly connected to the bottom of the inner wall of the slide rail 12 by bolts. The two anti-slip pads 17 are rubber pads with anti-slip texture on the surface. The two anti-slip pads 17 are fixedly bonded to the bottom end face of the control clamp 13 and the top end face of the support clamp 16, respectively. The motor 18 is a servo motor. The housing of the motor 18 is fixedly connected to the left end face of the insertion frame 2 by bolts, and the output shaft of the motor 18 horizontally passes through the insertion frame 2 and extends to the right side of the insertion frame 2. The output shaft of the motor 18 is connected to the insertion frame 2. A rotation gap is provided between the left side walls of the frame 2. The rotating plate 19 is a fan-shaped rotating block. The left end face of the rotating plate 19 is fixedly connected to the right end of the output shaft of the motor 18. The top of the rotating plate 19 is provided with an arc-shaped extrusion surface, which is in movable contact with the top end face of the control fixture 13. The second pull ring 20 is fixedly connected to the center of the top end face of the control fixture 13. After the insertion frame 2 is installed, the operator pulls the control fixture 13 upward along the guide groove of the slide rail 12 through the second pull ring 20, so that sufficient space is opened between the control fixture 13 and the support fixture 16. The steel strip to be processed is placed in the clamping area between the control fixture 13 and the support fixture 16. Then the control system starts the motor 18 to work, and the output shaft of the motor 18 rotates clockwise to drive The rotating plate 19 fixed at its right end rotates synchronously. During the rotation, the arc-shaped extrusion surface at the top of the rotating plate 19 contacts the top end face of the control clamp 13 and pushes the control clamp 13 to slide smoothly downward along the guide groove of the slide rail 12. When the control clamp 13 descends, it drives the extension frame 14 fixed at its front side to descend synchronously. When the extension frame 14 descends, it compresses the No. 3 spring 15 between its bottom and the front side of the insertion frame 2 to store elastic potential energy. At the same time, the control clamp 13 moves closer to the support clamp 16. The anti-slip pad 17 at the bottom of the control clamp 13 and the anti-slip pad 17 at the top of the support clamp 16 move closer to each other and apply a uniform clamping force to both sides of the steel strip. The anti-slip texture on the surface of the anti-slip pad 17 increases the friction between it and the steel strip, thereby completing the stable clamping and positioning of the steel strip.

[0030] In this embodiment, the top of the connecting bracket 1 is provided with a sliding groove, and the bottom of the control plate 4 is provided with a sliding protrusion. The sliding protrusion is slidably connected to the inner wall of the sliding groove. The sliding groove and the sliding protrusion cooperate to guide and limit the sliding of the control plate 4. The connecting bracket 1 is provided with a first guide hole. The outer wall of the hollow column 6 is slidably connected to the inner wall of the first guide hole. The first guide hole guides the vertical sliding of the hollow column 6, ensuring that the hollow column 6 rises and falls smoothly in the vertical direction.

[0031] In this embodiment, a second guide hole is provided inside the hollow column 6. The outer wall of the limiting frame 7 is slidably connected to the inner wall of the second guide hole. The second guide hole guides the vertical sliding of the limiting frame 7. A snap-fit ​​protrusion is provided at the top of the limiting frame 7. The snap-fit ​​protrusion is movably snapped into the inner wall of the limiting groove. The snap-fit ​​protrusion and the limiting groove engage to achieve quick locking of the insertion frame 2. The first spring 8 is a tension spring. When the limiting frame 7 descends, the first spring 8 is stretched to store elastic potential energy. When the limiting frame 7 is aligned with the limiting groove, the elastic potential energy is released to pull the limiting frame 7 upward to complete the snap-fit.

[0032] In this embodiment, the slide rail 12 is provided with a guide groove, and the outer wall of the control clamp 13 is slidably connected to the inner wall of the guide groove. The guide groove guides the vertical sliding of the control clamp 13. A through groove is provided on the front side of the slide rail 12, and the front end of the extension frame 14 passes through the through groove and extends to the outside of the slide rail 12. The extension frame 14 extends through the through groove to the outside of the slide rail 12, which facilitates the application of elastic force to the extension frame 14 by the third spring 15. The third spring 15 is a compression spring. When the control clamp 13 descends, the third spring 15 is compressed and stores elastic potential energy. When the motor 18 works in the reverse direction, the elastic potential energy is released to push the control clamp 13 to rise and reset.

[0033] In this embodiment, a rotation gap is provided between the output shaft of the motor 18 and the left side wall of the insertion frame 2. The rotation gap ensures that the output shaft of the motor 18 does not interfere with the left side wall of the insertion frame 2 during rotation. The top of the rotating plate 19 is provided with an arc-shaped extrusion surface. The arc-shaped extrusion surface is in active contact with the top end face of the control fixture 13. During the rotation of the rotating plate 19, the arc-shaped extrusion surface makes smooth contact with the top end face of the control fixture 13 and pushes the control fixture 13 to descend smoothly. Both anti-slip pads 17 are rubber pads. The rubber pads protect the surface of the steel strip and prevent indentations during clamping.

[0034] In this embodiment, two anti-slip pads 17 are fixedly bonded to the bottom end face of the control clamp 13 and the top end face of the support clamp 16, respectively. The two anti-slip pads 17 are provided with anti-slip textures on the side that is close to each other. The anti-slip textures increase the friction between the anti-slip pads 17 and the surface of the steel strip, prevent the steel strip from sliding during the clamping process, and improve the stability and reliability of the clamping.

[0035] Working principle: In actual use, when the insertion frame 2 needs to be installed, the insertion frame 2 is inserted horizontally into the connecting bracket 1. At this time, the control system starts the electric push rod 3. The output end of the electric push rod 3 extends to the left, pushing the control plate 4, which is fixedly connected to its output end, to slide to the left along the top of the connecting bracket 1. When the control plate 4 slides to the left, it drives the pull plate 5, which is rotatably connected to its front side, to move to the left. The pull plate 5 pulls the hollow column 6, which is rotatably connected to its top, to slide downward along the first guide hole in the connecting bracket 1. When the hollow column 6 slides downward, it drives the limiting frame 7 inside it to descend synchronously and pass through the insertion frame 2. The operator pulls the first pull ring 10 to make the sliding frame 9 slide to the left along the bottom of the connecting bracket 1. When sliding 9 slides to the left, it compresses the second spring 11 between its right side and the left side of the connecting bracket 1 to store elastic potential energy. At this time, the limiting frame 7 is rotated so that the snap-fit ​​protrusion on the top of the limiting frame 7 aligns with the limiting groove at the bottom of the insertion frame 2. The first spring 8 releases its elastic potential energy and pulls the limiting frame 7 up along the second guide hole in the hollow column 6, so that the snap-fit ​​protrusion on the top of the limiting frame 7 snaps into the limiting groove, completing the snap-fit ​​engagement. Then, the first pull ring 10 is released, and the second spring 11 releases its stored elastic potential energy to push the sliding frame 9 to slide back to the right. The right end face of the sliding frame 9 contacts the bottom of the limiting frame 7, limiting the limiting frame 7 and preventing it from exiting the limiting groove, thus completing the quick installation and fixing of the insertion frame 2. When the insertion frame 2 is installed... After installation, the operator pulls the control clamp 13 upward along the guide groove of the slide rail 12 using the second pull ring 20, creating sufficient space between the control clamp 13 and the support clamp 16. The steel strip is then placed within the clamping area between the control clamp 13 and the support clamp 16. Subsequently, the control system starts the motor 18. The output shaft of the motor 18 rotates, causing the rotating plate 19 fixed to its right end to rotate synchronously. During rotation, the arc-shaped pressing surface at the top of the rotating plate 19 contacts the top end face of the control clamp 13 and pushes the control clamp 13 downward along the slide rail 12. As the control clamp 13 descends, it causes the extension frame 14 fixed to its front side to descend synchronously. When the extension frame 14 descends, it compresses its bottom surface and... The No. 3 spring 15 between the front sides of the insertion frame 2 stores elastic potential energy, while controlling the clamp 13 to move closer to the support clamp 16. The anti-slip pad 17 at the bottom of the clamp 13 and the anti-slip pad 17 at the top of the support clamp 16 move closer to each other and apply a uniform clamping force to both sides of the steel strip, thereby completing the clamping and positioning of the steel strip. When it is necessary to change the clamp model, the operator pulls the No. 1 pull ring 10 to make the sliding frame 9 slide to the left. After the sliding frame 9 moves to the left, it releases the limit on the bottom of the limiting frame 7. At this time, press down on the limiting frame 7 to make the locking protrusion exit the limiting groove, and the insertion frame 2 can be quickly pulled out from the connecting bracket 1 to replace the insertion frame 2 with a clamping and positioning mechanism of different specifications, thus achieving rapid model change.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
