Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tooling, in particular to a stamping part clamping structure and a stamping part gauge. BACKGROUND

[0002] The stamping part gauge is a tool specially used for detecting the size and shape precision of stamping parts. It is usually designed and manufactured according to the three-dimensional model of the stamping part and is made through high-precision processing technology. It is widely used in the automobile manufacturing, aerospace, electronic and electrical industries. The stamping part gauge can quickly and accurately detect whether the key size, hole position and contour of the stamping part meet the design requirements, help to find quality problems in the production process in time, and improve the production efficiency and product quality.

[0003] Some gauges use electromagnets to adsorb workpieces. The electromagnets are installed on the gauge to be close to or in contact with the workpiece. After being powered on, the electromagnets generate magnetic force to adsorb the workpiece, thereby quickly fixing the workpiece. This technology is not only simple to operate and occupies small space, but also can provide stable clamping force to ensure the stability and accuracy of the detection process. In addition, auxiliary devices such as positioning pins can be combined to further improve the detection accuracy, and it is widely used in the fixing and detection of metal workpieces.

[0004] However, in the prior art, when quality inspection is performed on workpieces with different structural shapes, the electromagnets cannot be adjusted for different workpieces, resulting in the situation that the electromagnets cannot adsorb the workpieces. That is, the stamping part gauge in the prior art cannot perform quality inspection on workpieces with different shapes, and the applicability is poor. CONTENT OF THE INVENTION

[0005] The present application at least solves one of the technical problems in the related art to some extent.

[0006] Therefore, the application aims to provide a stamping part clamping structure and a stamping part gauge, which can adjust the height of the corresponding electromagnet according to the workpiece with different shapes, that is, the stamping part clamping structure can be used after simple adjustment for the workpiece with different shapes, thereby improving the applicability of the stamping part clamping structure.

[0007] To achieve the above-mentioned purpose, the present application provides a stamping part clamping structure, which comprises:

[0008] a support seat;

[0009] a connecting piece, which is slidably connected to the support seat in the vertical direction;

[0010] a first locking piece, which is used to fix the relative position of the connecting piece and the support seat;

[0011] an electromagnet, which is fixed to the top end of the connecting piece and is used to adsorb the workpiece after being powered on.

[0012] After moving the connecting piece up and down to the desired position, the relative position of the connecting piece and the support seat is fixed by the first locking piece, the workpiece is adsorbed by the electromagnet, and the position of the workpiece is fixed.

[0013] In the technical scheme, when the connecting piece is moved, the height of the electromagnet at the top of the connecting piece is also adjusted. The vertical sliding function of the connecting piece allows the user to adjust the position according to the height requirement of the workpiece, the first locking piece ensures the relative position of the connecting piece and the support seat, and the electromagnet adsorbs the workpiece by energization to realize fast and stable clamping, thereby improving the clamping efficiency and precision. The height of the corresponding electromagnet can be adjusted according to different shapes of the workpiece, that is, the stamping part clamping structure can be used after simple adjustment for different shapes of the workpiece, thereby improving the applicability of the stamping part clamping structure.

[0014] In some embodiments of the present application, a first sliding groove vertically arranged in the length direction is formed through the connecting piece;

[0015] The first locking piece is a first screw, the first screw is arranged through and threadedly connected to the support seat, and the first screw is located in the first sliding groove;

[0016] When the head of the first screw abuts the connecting piece to the support seat, the relative position of the support seat and the connecting piece is fixed.

[0017] In the technical scheme, after the connecting piece is slid on the support seat to the corresponding height, the first screw is rotated, the connecting piece is abutted by the head of the screw, and the connecting piece and the support seat are tightly fixed. This structure is simple and reliable, easy to operate, and at the same time, the design of the first sliding groove allows the connecting piece to be flexibly adjusted in the vertical direction, thereby improving the applicability and flexibility of the clamping structure.

[0018] In some embodiments of the present application, a second sliding groove is formed in one of the vertical side walls of the support seat;

[0019] A second sliding block is formed on the connecting piece, and the second sliding block is slidably connected in the second sliding groove;

[0020] The cross section of the second sliding groove is trapezoidal, and the shorter top edge of the second sliding groove is the opening of the second sliding groove.

[0021] In the technical scheme, the connecting piece is slid on the support seat through the second sliding block, and the trapezoidal second sliding groove and the second sliding block matched with each other avoid the possibility that the second sliding block is separated from the second sliding groove, so that the connecting piece can only slide on the support seat in the vertical direction.

[0022] In some embodiments of the present application, the first locking member is a second bolt, the second bolt penetrates and is threadedly connected to the connecting member, and when the end of the second bolt abuts against the support base, the relative position between the support base and the connecting member is fixed.

[0023] In the technical solution, because the trapezoidal second sliding groove and the second sliding block are connected to avoid the disconnection of the connecting member from the support base, when the second bolt abuts against the support base, the force that moves the support base and the connecting member away from each other increases the pressure between the second sliding groove and the second sliding block, thereby increasing the friction and fixing the connecting member and the support base.

[0024] In some embodiments of the present application, the first locking member is a bolt that penetrates the connecting member and is slidably connected to the connecting member in the horizontal direction.

[0025] A plurality of positioning holes for inserting the bolt are arranged on the support base in the vertical direction.

[0026] In the technical solution, the user can select a suitable positioning hole to fix the bolt according to the need, which not only improves the flexibility of clamping, but also reduces the operation time and improves the clamping efficiency. The sliding design of the bolt allows the user to quickly adjust the position of the connecting member and fix it through the bolt, which is simple to operate and accurate in positioning. The arrangement of multiple positioning holes enables the clamping structure to adapt to the needs of workpieces of different heights, further improving the applicability and universality of the clamping structure. Moreover, the connection strength between the connecting member and the support base in this design is high, and the weight of the workpiece is too large to lower the height of the electromagnet and the connecting member.

[0027] In some embodiments of the present application, the connecting member includes a horizontal segment and a vertical segment, the horizontal segment is arranged at the top end of the vertical segment, and the vertical segment is slidably connected to the support base.

[0028] In the technical solution, this segmented design makes the sliding of the connecting member in the vertical direction more stable, and provides a more reasonable space layout for the installation of the electromagnet. The structure optimization of the horizontal segment and the vertical segment further improves the overall performance and reliability of the clamping structure. The design of the horizontal segment provides stable support for the installation of the electromagnet, ensuring that the electromagnet can work normally when it is attracted to the workpiece. The sliding connection design of the vertical segment enables the connecting member to flexibly adjust the height to adapt to the needs of different workpieces, improving the flexibility and applicability of the clamping structure.

[0029] In some embodiments of the present application, the bottom of the horizontal segment penetrates and is threadedly connected to a threaded connecting member, and the top end of the threaded connecting member penetrates and is threadedly connected to the electromagnet.

[0030] In the technical scheme, the electromagnet can be disassembled through the threaded connecting piece at the bottom end of the horizontal section, users can replace electromagnets of different specifications according to needs to adapt to the adsorption needs of different workpieces, and the universality and applicability of the clamping structure are improved. The design of the threaded connecting piece also makes the installation and disassembly of the electromagnet more convenient, reduces the maintenance and replacement time, and improves the work efficiency.

[0031] In a second aspect, the utility model provides a stamping part clamping structure, it includes:

[0032] Support seat;

[0033] Connecting piece, the connecting piece sets up in support seat top;

[0034] At least one gasket, the gasket is used for setting up between the connecting piece and the support seat;

[0035] Second locking piece, the second locking piece is used for fixing the connecting piece to the support seat;

[0036] Electromagnet, the electromagnet is fixed to the top end of the connecting piece;

[0037] According to demand, the gasket is stacked between the connecting piece and the support seat, the relative position of the connecting piece and the support seat is fixed through the second locking piece, the workpiece is adsorbed by the electromagnet, and the position of the workpiece is fixed.

[0038] In the technical scheme, the height of the connecting piece is adjusted by setting the gasket between the connecting piece and the support seat and fixing the relative position by the second locking piece, so as to adjust the height of the electromagnet. The use of the gasket can be flexibly adjusted according to the actual height requirement of the workpiece, and the applicability and precision of the clamping structure are improved. The use of the second locking piece ensures the relative position of the connecting piece and the support seat, avoids displacement caused by vibration or external force, and further improves the stability and reliability of clamping. The above scheme can adjust the height of the corresponding electromagnet according to the workpiece of different shapes, that is, it can be used after simple adjustment for workpieces of different shapes, improving the applicability of the stamping part clamping structure.

[0039] In some embodiments of the application, the support seat is a resin block.

[0040] In the technical scheme, not only the overall weight of the clamping structure is reduced, but also the corrosion resistance and insulation performance are improved. The use of resin material enables the support seat to maintain good performance in humid or chemically corrosive environments, prolonging the service life of the clamping structure and reducing production costs. The lightweight design of the resin support seat makes the clamping structure more convenient to carry and install, improving work efficiency. The corrosion resistance and insulation performance enable the clamping structure to work normally in harsh environments, further improving the reliability and durability of the clamping structure.

[0062] In the following, the present application will be described in detail by exemplary embodiments. However, it should be understood that the elements, structures and features in one embodiment can also be beneficially combined into other embodiments without further description.

[0063] It should be noted that in the field of automobiles, a large number of structural parts are formed by stamping, and in order to control errors, the workpiece is usually installed on a gauge for detection. After the workpiece is fixed by the clamping structure, the workpiece is detected by the detection module.

[0064] In the prior art, the height of the clamping structure is not adjustable, and it can only detect one kind of workpiece.

[0065] Therefore, the present application provides a stamping part clamping structure and a stamping part gauge, which adjusts the height of the electromagnet on the connecting piece according to the needs by setting the support seat and the connecting piece sliding on the support seat, and locking the relative position of the support seat and the connecting piece by the locking piece. The effect of solving the problem of poor applicability of the existing gauge can be adjusted according to different workpieces.

[0066] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0067] As shown in the accompanying drawings Figures 1 to 3As shown, in one illustrative embodiment of the stamping piece clamping structure of the present application, the stamping piece clamping structure comprises a support seat 100, which serves as the installation basis of the structure through the support seat 100. It can be provided on the bottom plate 700 of the stamping piece testing fixture.

[0068] In some embodiments, the stamping piece clamping structure comprises a connecting piece 200, which is slidably connected to the support seat 100 in the vertical direction. The position of the connecting piece 200 in the vertical direction can be manually adjusted according to requirements.

[0069] In some embodiments, the stamping piece clamping structure comprises a first locking piece 500, which is used to fix the relative position of the connecting piece 200 and the support seat 100. The first locking piece 500 fixes the height position of the connecting piece 200 and the support seat 100, avoids the falling of the connecting piece 200, and ensures the stability of the structure.

[0070] In some embodiments, the stamping piece clamping structure comprises an electromagnet 400, which is fixed to the top end of the connecting piece 200. The electromagnet 400 is used to adsorb the workpiece after being energized. After moving the connecting piece 200 up and down to the desired position, the relative position of the connecting piece 200 and the support seat 100 is fixed by the first locking piece 500, the workpiece is adsorbed by the electromagnet 400, and the position of the workpiece is fixed.

[0071] Through the above scheme, when the connecting piece 200 is moved, the height of the electromagnet 400 at the top is also adjusted. The vertical sliding function of the connecting piece 200 allows the user to adjust the position according to the height requirements of the workpiece, the first locking piece 500 ensures the relative position of the connecting piece 200 and the support seat 100, and the electromagnet 400 adsorbs the workpiece by energization, realizes quick and stable clamping, improves the clamping efficiency and precision. The height of the corresponding electromagnet 400 can be adjusted according to different shapes of the workpiece, that is, it can be used after simple adjustment for different shapes of the workpiece, improving the applicability of the stamping piece clamping structure.

[0072] In some embodiments, the support seat 100 can be a rectangular block. The structure of the rectangular block is simple and easy to manufacture, can provide stable support and guiding effect for the connecting piece 200, and ensure the stability and precision of the sliding of the connecting piece 200 in the vertical direction. Secondly, the support seat 100 of the rectangular block has a large contact area, which can uniformly disperse the weight and clamping force of the workpiece, thereby improving the stability and reliability of the overall structure.

[0073] In another embodiment, the support seat 100 can also be a trapezoidal structure. The support seat 100 of the trapezoidal structure has good stability, the wider bottom can provide a larger support area, enhance the anti-overturning ability of the overall structure, and ensure the stability of the clamping process.

[0074] It is worth noting that the shape of the support seat 100 can also be a triangle, a parallelogram, or other shapes or irregular shapes.

[0075] Please refer to Figures 1 to 6 In some embodiments, the connecting piece 200 includes a horizontal section 201 and a vertical section 202, the horizontal section 201 is arranged at the top end of the vertical section 202, and the vertical section 202 is slidingly connected to the support seat 100. This segmented design makes the sliding of the connecting piece 200 in the vertical direction more stable, and at the same time provides a more reasonable space layout for the installation of the electromagnet 400. The structure optimization of the horizontal section 201 and the vertical section 202 further improves the overall performance and reliability of the clamping structure. The design of the horizontal section 201 provides stable support for the installation of the electromagnet 400, ensuring that the electromagnet 400 can work normally when it is adsorbed to the workpiece. The sliding connection design of the vertical section 202 makes the connecting piece 200 can be flexibly adjusted in height, adapt to the needs of different workpieces, and improve the flexibility and applicability of the clamping structure.

[0076] In some embodiments, the horizontal section 201 is a rectangular plate. The rectangular horizontal section 201 provides a stable mounting platform for the electromagnet 400, ensuring that it can be uniformly stressed when it is adsorbed to the workpiece, avoiding uneven adsorption or shaking due to unstable installation. At the same time, the structure of the rectangular plate is simple and easy to process, and can be closely combined with the vertical section 202 to form a stable segmented connecting plate structure.

[0077] In some embodiments, the horizontal section 201 can also be a trapezoidal plate or other structural shapes.

[0078] In some embodiments, the vertical section 202 is a rectangular plate. Its structure is simple and easy to manufacture, and can be closely matched with the first sliding groove 2021 or the second sliding block 300 of the support seat 100, ensuring smooth sliding and precise positioning of the connecting plate in the vertical direction. Its large contact area can evenly distribute the friction and locking force during sliding, reducing local wear and tear and prolonging the service life.

[0079] In some embodiments, the vertical section 202 can also be a trapezoidal plate or other structural shapes.

[0080] In some embodiments, the electromagnet 400 is cylindrical and is arranged vertically on the upper surface of the horizontal section 201. The cylindrical electromagnet 400 has a simple structure and good symmetry, which can provide uniform adsorption force, ensuring that the workpiece is evenly stressed during clamping, avoiding workpiece deformation or unstable clamping due to uneven adsorption.

[0081] Please refer to Figures 1 to 3In some embodiments, a first sliding groove 2021 is vertically arranged on the connecting piece 200. The first locking piece 500 is a first bolt, which is arranged in and threadedly connected to the support base 100, and is located in the first sliding groove 2021. When the bolt head of the first bolt abuts against the connecting piece 200 to the support base 100, the relative position of the support base 100 and the connecting piece 200 is fixed. After the connecting piece 200 is slid to a corresponding height on the support base 100, the first bolt is rotated to abut against the connecting piece 200 by the bolt head, so that the connecting piece 200 and the support base 100 are tightly fixed. This structure is simple and reliable, and is convenient to operate. Meanwhile, the design of the first sliding groove 2021 allows the connecting piece 200 to be flexibly adjusted in the vertical direction, thereby improving the applicability and flexibility of the clamping structure.

[0082] Further, the first sliding groove 2021 is arranged on the vertical section 202, and the opening direction of the first sliding groove 2021 is the same as the thickness direction of the vertical section 202. Through this design, the stability of the sliding between the vertical section 202 and the support base 100 is improved. The first bolt does not need to be arranged too long, and a shorter first bolt can more stably abut against the vertical section 202 to the support base 100.

[0083] In some embodiments, a first sliding block is further arranged on the support base 100, and is arranged on the side of the support base 100 facing the vertical section 202. The first sliding block is slidably connected to the first sliding groove 2021. The cooperation between the first sliding block and the sliding groove provides a clear guide path for the movement of the vertical section 202, ensures the stable sliding of the vertical section 202 in the vertical direction without deviation, and effectively avoids the clamping error caused by unstable sliding.

[0084] Please refer to Figures 1 to 3 In some embodiments, the first sliding block and the first bolt are arranged in the vertical direction. Through this design, the direction of the first sliding groove 2021 is accurately limited to the vertical direction, and it is ensured that the first sliding block can only slide in the vertical direction. This structure effectively avoids the horizontal deviation or shaking of the sliding block during the sliding process, and significantly improves the stability and precision of the sliding.

[0085] Please refer to Figures 3 to 6 In other embodiments, a second sliding groove 101 is arranged on one side wall of the support base 100. A second sliding block 300 is arranged on the connecting piece 200, and is slidably connected to the second sliding groove 101. The cross section of the second sliding groove 101 is trapezoidal, and the shorter top edge thereof is the opening of the second sliding groove 101. Through the above scheme, the connecting piece 200 is slid on the support base 100 through the second sliding block 300, and the trapezoidal second sliding groove 101 and the second sliding block 300 matched with each other avoid the possibility that the second sliding block 300 is separated from the second sliding groove 101, so that the connecting piece 200 can only slide on the support base 100 in the vertical direction.

[0086] Further, the length direction of the second sliding groove 101 is vertically arranged. The second sliding groove 101 is arranged on the side of the support frame facing the connecting piece 200. The side of the second sliding groove 101 facing the vertical section 202 is in communication with the outside. In this way, the second sliding block 300 can slide in the second sliding groove 101 along the length direction of the second sliding groove 101.

[0087] In some embodiments, the top of the second sliding groove 101 can pass through the support seat 100. The sliding block can be inserted into the second sliding groove 101 from the top of the second sliding groove 101.

[0088] In some embodiments, the bottom of the second sliding groove 101 can pass through the support seat 100. The sliding block can be inserted into the second sliding groove 101 from the bottom of the second sliding groove 101. It is worth noting that if this form is adopted, the support seat 100 and the bottom plate 700 of the gauge are detachably connected.

[0089] Please refer to Figures 3 to 6 In some embodiments, the first locking piece 500 is a second bolt, which penetrates and is threadedly connected to the connecting piece 200. When the end of the second bolt abuts against the support seat 100, the relative position of the support seat 100 and the connecting piece 200 is fixed. Because the trapezoidal second sliding groove 101 and the second sliding block 300 are connected, the connecting piece 200 is prevented from being separated from the support seat 100. Therefore, when the second bolt abuts against the support seat 100, the force that makes the support seat 100 and the connecting piece 200 move away from each other increases the pressure between the second sliding groove 101 and the second sliding block 300, thereby increasing the friction and achieving the fixation of the connecting piece 200 and the support seat 100.

[0090] Please refer to Figures 3 to 6 Further, the second bolt can penetrate the vertical section 202 and the second sliding block 300 in sequence and abut against the groove bottom of the second sliding groove 101. This design further enhances the connection strength and stability between the vertical section 202 and the support seat 100. Through the fastening effect of the bolt, the friction between the second sliding block 300 and the second sliding groove 101 is significantly increased, effectively preventing the vertical section 202 from sliding or loosening due to external force or vibration during clamping, and ensuring the reliability of the clamping structure when carrying the workpiece.

[0091] In some embodiments, the first locking member 500 is a through connector 200, and the through connector 200 is slidably connected to the plug in the horizontal direction. A plurality of positioning holes for plug insertion are arranged on the support seat 100 in the vertical direction. Users can select appropriate positioning holes for plug fixation according to needs. This design not only improves the flexibility of clamping, but also reduces the operation time and improves the clamping efficiency. The sliding design of the plug allows users to quickly adjust the position of the connector 200 and fix it through the plug, which is easy to operate and accurate in positioning. The arrangement of multiple positioning holes enables the clamping structure to adapt to the needs of workpieces of different heights, further improving the applicability and universality of the clamping structure. Moreover, the connection strength between the connector 200 and the support seat 100 in this design is high, and the weight of the workpiece will not cause the height of the electromagnet 400 and the connector 200 to be lowered.

[0092] Further, the spacing between any two adjacent positioning holes is the same. This design provides a uniform and standardized adjustment interval for the clamping structure, allowing users to quickly and accurately adjust the position of the vertical section 202 according to the height requirements of the workpiece. Uniform spacing ensures consistent increments for each adjustment, making it easy for operators to perform standardized operations and reducing clamping errors caused by inaccurate position adjustments.

[0093] In some embodiments, the bottom of the horizontal section 201 has a threaded connector, and the top end of the threaded connector is threaded to the electromagnet 400. The threaded connector at the bottom of the horizontal section 201 allows the electromagnet 400 to be detached, and users can replace different specifications of electromagnets 400 as needed to meet the adsorption needs of different workpieces, improving the universality and applicability of the clamping structure. The threaded connector design also makes it easier to install and remove the electromagnet 400, reducing maintenance and replacement time, and improving work efficiency.

[0094] In some embodiments, the threaded connector includes, but is not limited to, a bolt, a screw, and a screw.

[0095] In some embodiments, the threaded connector is coaxially connected to the electromagnet 400 after passing through the horizontal section 201, further improving the stability of the connection between the electromagnet 400 and the horizontal section 201.

[0096] In some embodiments, the threaded connector can also be threaded to the horizontal section 201 after passing through the electromagnet 400 from top to bottom.

[0097] Please refer to Figure 7 and Figure 8 , in the second aspect, the utility model provides a stamping part clamping structure, which comprises a support seat 100, which is used as the installation basis of the structure. It can be arranged on the bottom plate 700 of the stamping part testing tool.

[0098] In some embodiments, the stamping piece clamping structure comprises a connecting piece 200 arranged on the top of the support base 100.

[0099] In some embodiments, the stamping piece clamping structure comprises at least one gasket 600 arranged between the connecting piece 200 and the support base 100.

[0100] In some embodiments, the stamping piece clamping structure comprises a second locking piece 900 for fixing the connecting piece 200 to the support base 100.

[0101] In some embodiments, the stamping piece clamping structure comprises an electromagnet 400 fixed to the top end of the connecting piece 200.

[0102] According to the needs, the gasket 600 is stacked between the connecting piece 200 and the support base 100, the relative position of the connecting piece 200 and the support base 100 is fixed by the second locking piece 900, and the workpiece is adsorbed by the electromagnet 400 to realize the position fixation of the workpiece.

[0103] Through the above scheme, by arranging the gasket 600 between the connecting piece 200 and the support base 100 and fixing the relative position by the second locking piece 900, the height adjustment function of the connecting piece 200 is realized to adjust the height of the electromagnet 400. The use of the gasket 600 can be flexibly adjusted according to the actual height requirement of the workpiece, improving the applicability and precision of the clamping structure. The use of the second locking piece 900 ensures the relative position fixation of the connecting piece 200 and the support base 100, avoiding displacement caused by vibration or external force, further improving the stability and reliability of the clamping. The above scheme can adjust the height of the corresponding electromagnet 400 according to different shapes of workpieces, i.e. it can be used after simple adjustment for different shapes of workpieces, improving the applicability of the stamping piece clamping structure.

[0104] In some embodiments, the support base 100 is a resin block. Not only reduces the overall weight of the clamping structure, but also improves its corrosion resistance and insulation performance. The use of resin material makes the support base 100 still maintain good performance in humid or chemically corrosive environment, prolongs the service life of the clamping structure, and reduces the production cost. The lightweight design of the resin support base 100 makes the clamping structure more convenient to carry and install, improving the work efficiency. Its corrosion resistance and insulation performance make the clamping structure still work normally in harsh environment, further improving the reliability and durability of the clamping structure.

[0105] In some embodiments, the connecting piece 200 is a rectangular block. The rectangular block connecting piece 200 has a large contact area and a uniform stress distribution, which can effectively disperse the weight and adsorption force of the electromagnet 400, ensuring the stability of the connection and avoiding loosening or damage caused by local stress concentration. At the same time, the rectangular block shape is regular and easy to manufacture.

[0106] In some embodiments, the gasket 600 is a rectangular plate. The rectangular plate-shaped gasket 600 can provide a stable support surface to ensure the parallelism and contact stability between the connecting plate and the support seat 100, thereby improving the overall precision of the clamping structure. Its regular shape facilitates processing and stacking combination, and the number of gaskets 600 can be flexibly adjusted according to the height requirements of the workpiece to achieve precise adjustment of the height of the connecting plate.

[0107] In some embodiments, the thickness of each gasket 600 can be the same. This design enables the gasket 600 to provide uniform and standardized height adjustment function. By using gaskets 600 of the same thickness, users can quickly calculate the required number of gaskets 600 according to the height requirements of the workpiece, achieving precise height adjustment and ensuring the repeatability and consistency of the clamping structure. In addition, gaskets 600 of the same thickness facilitate mass production and quality control, reducing production costs and inventory management difficulty.

[0108] In some embodiments, the thickness of each gasket 600 can be different. Users can make more detailed adjustments according to the specific height requirements of the workpiece without the need for a large number of gaskets 600 of the same thickness, thereby reducing the number of gaskets 600 and the complexity of the overall structure. This diverse thickness selection can meet a wider range of workpiece height requirements, further improving the applicability and versatility of the clamping structure.

[0109] In some embodiments, the second locking piece 900 is a third bolt, which is threaded into the mounting seat along the vertical direction from top to bottom after penetrating the connecting piece 200. When the third bolt is tightened, each gasket 600 is stacked and pressed between the connecting plate and the mounting seat. This ensures the close fit between the gaskets 600 and between the gaskets 600 and the connecting plate and the mounting seat, thereby improving the stability and reliability of the entire clamping structure. This design not only effectively prevents the displacement or loosening of the gaskets 600 during work, but also allows for fine adjustment of the height through the tightening force of the bolt, further optimizing the clamping precision. In addition, the use of the third bolt simplifies the locking operation, facilitating quick installation and disassembly, and improving the clamping efficiency.

[0110] In some embodiments, the number of second locking members 900 can be multiple. The fixing strength and stability of the gasket 600 between the connecting plate and the mounting seat can be significantly enhanced. Uniform distribution of multiple locking members can ensure uniform stress of the gasket 600 after lamination, avoid stress concentration or local deformation caused by single-point locking, and thus improve the reliability and accuracy of the entire clamping structure. In addition, multi-point locking can better adapt to the combination of gaskets 600 of different thicknesses and quantities, further optimizing the adjustment range and flexibility of the clamping height. This design not only enhances the stability of the clamping structure, but also enhances its adaptability under complex working conditions, meets diversified clamping needs, and simplifies the operation process, facilitating quick installation and disassembly.

[0111] In some embodiments, a threaded sleeve is embedded in the mounting seat, and a third bolt is used for threaded connection to the threaded sleeve.

[0112] In some embodiments, the second locking member 900 can also be a buckle or the like.

[0113] Please refer to Figures 9 to 11 In a third aspect, the utility model provides a stamping part gauge, including bottom plate 700, bottom plate 700 is provided with at least one stamping part clamping structure as described above.

[0114] In some embodiments, a stamping part gauge includes a control switch 800, which is provided on the bottom plate 700 and controls the power supply of the electromagnet 400 through the control switch 800.

[0115] Through the above scheme, the clamping structure and the gauge bottom plate 700 are integrated, realizing the integration of rapid clamping and detection of the workpiece. The setting of the control switch 800 makes the operation of the electromagnet 400 more convenient, and the user can easily control the on-off of the electromagnet 400, improving the detection efficiency and operation convenience. The design of the bottom plate 700 allows multiple clamping structures to be installed simultaneously, improving the batch processing capacity of the detection. The convenient operation of the control switch 800 allows the user to quickly switch the on-off state of the electromagnet 400, reducing the operation time and improving the work efficiency.

[0116] In some embodiments, a plurality of plug-in rods are provided on the bottom plate 700, which are connected to the plug-in holes on the workpiece to realize precise positioning of the workpiece.

[0117] In some embodiments, the stamping part gauge further includes a detection module for detecting the workpiece.

[0118] In some embodiments, the stamping part gauge is powered by an external 220V power supply.

[0119] In some embodiments, the stamping part gauge also has an adjustable power supply with a voltage of 0-24V.

[0120] It can be understood that the control switch 800 can control each stamping part clamping structure respectively.

[0121] In some embodiments, the specification of the electromagnet 400 mainly considers two parameters of suction force and diameter.

[0122] Further, the suction force is determined according to the Autoform (sheet forming simulation software) process analysis standard, and in order to avoid distortion of analysis data, the clamping force of the clamping springback is required to be ≤30N, and the suction force of the electromagnet 400 is required to be ≤30N.

[0123] Further, the electromagnet 400 has a suction cup, that is, a region with magnetism when the electromagnet 400 generates suction force. The diameter of the suction cup of the electromagnet 400 mainly considers the modeling structure of the workpiece, and in general, the position of the RPS (Reference Point System, a system for unified reference points in product design, manufacturing, testing and assembly processes) reference surface is generally more than 8mm (less than 8mm, the RPS cannot be arranged, affecting the stability of the workpiece positioning) in width, the diameter of the suction cup of the electromagnet 400 is ≥8mm, and at the same time, considering that when the diameter of the suction cup is too large, a gap (caused by the non-planar surface of the workpiece) or interference with the R angle or features of the workpiece between the suction cup of the electromagnet 400 and the surface of the workpiece being attracted may occur, combined with the commonly used positioning surface standard parts φ10mm, 16mm*16mm*5mm (circumscribed circle diameter φ22.6mm) on the gauge, the outer diameter of the electromagnet 400 is <φ22.6mm.

[0124] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and the ordinary skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
