Description

Technical Field

[0001] This utility model relates to the technical field of large circular knitting machine parts processing, specifically a low-stress clamping device for large circular knitting machine parts. Background Technology

[0002] Large circular knitting machine parts processing requires clamping to ensure stable positioning and accuracy of the workpiece during processing, prevent displacement or deformation, and thus guarantee processing accuracy and surface quality. However, existing low-stress clamping devices for large circular knitting machine parts have certain defects. Current clamping devices cannot balance the stability and convenience of the fixing method, and the force distribution when fixing samples is not ideal, which can easily lead to curling of parts and affect the subsequent processing effect.

[0003] To overcome the above-mentioned defects, the prior art (Chinese Patent No. CN117848957A, Publication Date: April 9, 2024) provides a low-stress sample clamping device and structure, belonging to the field of medical devices. It includes a tray with a mounting groove for placing the sample to be clamped. The tray also includes a first adsorption element and a magnetic suction pressure assembly. The first adsorption element is fixed to the tray. The magnetic suction pressure assembly includes a base frame, a second adsorption element fixed to the base frame, and a pressure column floatingly connected to the base frame. The first and second adsorption elements adsorb to position the magnetic suction pressure assembly and the tray. The pressure column abuts against the upper surface of the sample to be clamped, positioning the sample in the mounting groove. The magnetic suction pressure assembly and the tray are magnetically connected, simplifying the loading and removal of the sample. The pressure column, floatingly connected to the base frame and pressing against the upper surface of the sample, ensures uniform force on the sample, resulting in low overall stress and minimal damage. Furthermore, the pressure-type positioning makes the sample clamping device suitable for various samples, such as glass slides and culture dishes.

[0004] While existing technologies can achieve clamping, the overall clamping structure achieved by connecting the magnetic suction and pressure column in a floating manner is quite complex. This not only increases manufacturing costs but may also lead to a higher failure rate. Furthermore, the magnetic suction and pressure component may be affected by external magnetic field interference, resulting in unstable adsorption force and thus affecting the positioning accuracy of the clamped parts. The floating connection of the pressure column to the base frame leads to uneven pressure distribution, which may cause excessive or insufficient local force, thereby affecting processing accuracy and quality.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing low-stress clamping devices for large circular knitting machine components. Therefore, we propose a low-stress clamping device for large circular knitting machine components that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a low-stress clamping device for large circular knitting machine parts, in order to solve the problems mentioned in the background art. The current market structure for overall clamping by floating connection of magnetic suction and pressure column is relatively complex, which not only increases manufacturing costs but may also lead to a high failure rate. Furthermore, the magnetic suction and pressure column may be affected by external magnetic field interference, resulting in unstable adsorption force, which affects the positioning accuracy of the clamped parts. The floating connection of the pressure column to the base frame leads to uneven pressure distribution, which may cause excessive or insufficient local force, thereby affecting the processing accuracy and quality.

[0014] Preferably, the auxiliary seat has a second through hole, the auxiliary seat is located inside the storage slot, and a fixing block for connecting the rotating disk is provided at the bottom of the storage slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-stress clamping device for large circular knitting machine parts features a rotating component under the rotating disk, a simple overall structure, and reduces the instability caused by magnetic attraction. The entire device moves synchronously through symmetrically arranged sliders, ensuring uniform clamping of the limiting blocks, avoiding localized stress concentration, protecting the parts from damage during clamping, improving the service life of the parts, and enhancing the accuracy and quality of subsequent processing. The specific details are as follows:

[0016] (1) The rotating parts under the rotating disk rotate to facilitate the effective clamping of the limit block. The overall structure is simple, which reduces the problem of unstable adsorption caused by the use of magnetic structure for fixation. The whole is moved synchronously by symmetrically set sliders, so that the limit block is clamped evenly and local stress concentration is avoided.

[0017] (2) The gas conveying component delivers gas to the inside of the sleeve through the conveying pipe, so that the temperature of the gas can be delivered to the lifting rod through the sleeve. The gas conveying component of this application is set inside the clamping box, which can be easily replaced with a gas conveying structure, so that the lifting rod can quickly deliver the temperature to the auxiliary seat.

[0018] (3) The auxiliary seat delivers temperature inside the storage slot of the rotating disk, thereby keeping the temperature of the circular knitting machine parts on the outside of the rotating disk uniform. The auxiliary seat adjusts the temperature of the parts to avoid thermal stress deformation caused by uneven temperature.

[0019] (4) The lifting plate is raised by the output end of the telescopic cylinder, so that the lifting rod on the lifting plate moves the auxiliary seat out of the storage slot of the rotating plate, which makes it convenient for the auxiliary seat to push out the circular knitting machine parts, so that the parts can be quickly disassembled. The overall structure is simple and convenient for maintenance operations.

[0020] (5) The gas inside the auxiliary seat is ejected through the second through hole, which makes it easy to clean the inside of the rotating disk's storage slot, reducing the workload of manual maintenance. The fixed block set under the rotating disk ensures that each component operates efficiently within the limited range, improving the safety and reliability of the overall clamping and disassembly process.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: In this example, the entire assembly moves synchronously via symmetrically arranged sliders 6, ensuring uniform clamping by the limiting blocks 10, avoiding localized stress concentration, and protecting the components from damage during clamping. Figures 1-5The technical solution shown includes a clamping box 1, inside which a motor 2 is installed. The output end of the motor 2 is connected to a slider 6 via a drive assembly. The sliders 6 are symmetrically arranged. A first support plate 7 is provided on the clamping box 1, and a groove 8 is formed on the first support plate 7. The sliders 6 are slidably connected inside the groove 8. A support block 9 is connected to the slider 6 via a bolt structure, and a limit block 10 is installed on the support block 9. The drive assembly includes a rotating shaft 3 installed at the output end of the motor 2. A rotating disk 4 is provided on the rotating shaft 3, and a storage groove 21 is formed on the rotating disk 4. The bottom of the rotating disk 4 is rotatably connected to the bottom of the slider 6 via a rotating component 5. The clamping box 1 is conveniently installed on the required machine. When the motor 2 inside the clamping box 1 is turned on, the output end of the motor 2 drives the rotating shaft 3 to rotate, causing the rotating disk 4 on the rotating shaft 3 to rotate, which facilitates the rotation of the rotating component 5 under the rotating disk 4, so that the slider 6 at the end of the rotating component 5 is on the first support plate 6. The slide plate 7 slides inside the groove 8, allowing the slider 6 to unfold and retract. The slider 6 is connected to the support block 9 via a threaded structure, making it easy to disassemble and adjust the limiting block 10 on the support block 9. This allows the limiting block 10 to effectively clamp the circular knitting machine parts, achieving automatic adjustment and precise positioning of the limiting block 10. The overall structure is simple, reducing the instability caused by using magnetic structures for fixation, and also reducing the increased cost and failure rate caused by complex limiting. The detachable design of the threaded connection facilitates the installation and removal of the limiting block 10, allowing the device to adapt to parts of different specifications. The entire device moves synchronously through symmetrically arranged sliders 6, ensuring uniform clamping of the limiting block 10, avoiding local stress concentration, protecting the parts from damage during clamping, improving the service life of the parts, facilitating effective processing of the parts, and improving the accuracy and quality of subsequent processing.

[0031] Example 2: In this example, the auxiliary seat 19 is used to regulate the temperature of the components, avoiding thermal stress deformation caused by uneven temperature, and ensuring the accuracy and performance of the circular knitting machine components during clamping and processing. Specifically, as follows... Figures 3-6As shown, a second support plate 11 is installed inside the clamping box 1. An air supply component 12 is provided on the second support plate 11. The output end of the air supply component 12 is connected to a conveying pipe 13. A sleeve 14 is connected to the end of the conveying pipe 13. A lifting rod 17 is connected through the sleeve 14. An auxiliary seat 19 is installed on the top of the lifting rod 17. When the air supply component 12 on the second support plate 11 is opened, the air supply component 12 conveys gas to the inside of the sleeve 14 through the conveying pipe 13, so that the temperature of the gas can be conveyed to the lifting rod 17 through the sleeve 14. The air supply component 12 of this application is set inside the clamping box 1, which can be easily replaced with a structure that conveys gas, so that the lifting rod 17 can quickly convey the temperature to the auxiliary seat 19. This allows the auxiliary seat 19 to convey the temperature inside the storage slot 21 of the rotating disk 4, thereby keeping the temperature of the circular knitting machine parts on the outside of the rotating disk 4 uniform. The temperature of the parts is regulated by the auxiliary seat 19 to avoid thermal stress deformation caused by uneven temperature, and to ensure the accuracy and performance of the circular knitting machine parts during clamping and processing.

[0032] Example 3: In this example, the gas inside the auxiliary seat 19 is ejected through the second through hole 20, which facilitates cleaning of the inside of the storage slot 21 of the rotating disk 4, reducing the workload of manual maintenance. Specifically, as follows... Figures 3-7As shown, a lifting assembly is provided on the second support plate 11. The lifting assembly includes a telescopic cylinder 15 mounted on the second support plate 11. The output end of the telescopic cylinder 15 is connected to a lifting plate 16. The lifting plate 16 is located at the bottom of the lifting rod 17. A first through hole 18 is opened on the bottom side of the lifting rod 17, and the first through hole 18 communicates with the inner cavity of the lifting rod 17. The inner cavity of the lifting rod 17 communicates with the inner cavity of the auxiliary seat 19. A second through hole 20 is opened on the auxiliary seat 19, and the auxiliary seat 19 is located inside the storage slot 21. The bottom of the storage slot 21 A fixing block 22 is provided for connecting the rotating disk 4. When the circular knitting machine parts need to be disassembled, the rotary motor 2 moves the limiting block 10 away from the surface of the circular knitting machine parts, making it easier to disassemble the parts. At this time, the telescopic cylinder 15 is opened, and the lifting plate 16 is raised through the output end of the telescopic cylinder 15. This causes the lifting rod 17 on the lifting plate 16 to move the auxiliary seat 19 out of the storage slot 21 of the rotating disk 4, making it easier for the auxiliary seat 19 to push out the circular knitting machine parts, allowing the parts to be quickly disassembled. The overall structure is simple and easy to maintain. At this time, the first through hole 18 of the lifting rod 17 moves into the sleeve 14, which facilitates the gas inside the sleeve 14 to be transported to the inner cavity of the lifting rod 17 through the first through hole 18 of the lifting rod 17. This allows the gas inside the lifting rod 17 to be transported to the inner cavity of the auxiliary seat 19. The gas inside the auxiliary seat 19 is ejected through the second through hole 20, which facilitates the cleaning of the storage slot 21 of the rotating disk 4 and reduces the workload of manual maintenance. Since the rotating disk 4 is provided with a fixed block 22, when the output end of the motor 2 drives the rotating disk 4 to rotate through the rotating shaft 3, the overall rotation angle is small. It is only necessary to rotate the rotating disk 4 within the range limited by the fixed block 22. This not only facilitates the effective clamping of the circular knitting machine parts by the upper limit block 10, but also reduces the problem of the lifting rod 17 being affected. This ensures that each component operates efficiently within the limited range and improves the safety and reliability of the overall clamping and disassembly process. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
