It is difficult to meet the requirements of high precision and fast clamping, resulting in low processing efficiency and a high scrap rate of finished products.

[0004] Therefore, a clamping and positioning device is urgently needed to solve the above problems. Utility Model Content

[0043] This embodiment discloses a clamping and positioning device, such as Figures 1-2As shown, a clamping and positioning device is used to hold a workpiece 100, which includes an inner ring cutting area 101 and an outer ring cutting area 102. The inner ring cutting area 101 is provided with a first connecting hole 1011, and the outer ring cutting area 102 is provided with a first positioning hole 1021. The clamping and positioning device includes a fixture table 1, a positioning component, a clamping component, and a locking component. The fixture table 1 is provided with a second positioning hole 11 and a first threaded hole 12. The positioning component includes a first positioning member, which can pass through the first positioning hole 1021 and the second positioning hole 11 to fix the position of the workpiece 100 relative to the fixture table 1. The clamping component includes a first clamping member 21, which is used to press the outer ring cutting area 102 against the fixture table 1. The locking component includes a first screw 31, which can pass through the first connecting hole 1011 and the first threaded hole 12 in sequence and lock, so that part of the inner ring cutting area 101 and part of the outer ring cutting area 102 can be cut by the cutting component. The cut-off piece is existing technology and will not be discussed in detail here.

[0044] The clamping and positioning device disclosed in this embodiment, during operation, places the workpiece 100 to be processed on the fixture table 1, positioning the first positioning member through the first positioning hole 1021 of the outer ring cutting area 102 and the second positioning hole 11 of the fixture table 1, and then uses the first clamping member 21 to press the outer ring cutting area 102 onto the fixture table 1. The first screw 31 passes through the first connecting hole 1011 of the inner ring cutting area 101 and the first threaded hole 12 of the fixture table 1 to lock it in place. The cutting member then cuts off part of the inner ring cutting area 101 and part of the outer ring cutting area 102. This clamping and positioning device, through the cooperation of positioning, clamping and locking structures, can quickly and accurately position the workpiece 100, reduce deformation, improve processing accuracy and efficiency, and reduce the scrap rate.

[0045] like Figure 1 As shown, in this embodiment, the workpiece 100 is formed by welding the workpiece body and the workpiece cover plate together. After the cutting and forming process, excess material is removed, and the final product is an integrated molded part in which the workpiece body 1031 and the workpiece cover plate 1032 are fixed by welding.

[0046] like Figures 2-4As shown, the remaining inner ring cut-out area 101 is provided with a third positioning hole 1012, and the tooling table 1 is provided with a fourth positioning hole 13. The positioning assembly also includes a second positioning member, which can pass through the third positioning hole 1012 and the fourth positioning hole 13 to fix the position of the workpiece 100 relative to the tooling table 1. The locking assembly also includes a second screw 32, the inner ring cut-out area 101 is provided with a second threaded hole 1013, and the tooling table 1 is provided with a second connecting hole 14. The second screw 32 can pass through the second connecting hole 14 and the second threaded hole 1013 in sequence and lock, so that the remaining outer ring cut-out area 102 can be cut by the workpiece. This enhances the positioning stability of the workpiece 100 and the tooling table 1, effectively preventing the workpiece 100 from undergoing slight displacement or deformation when cutting the remaining outer ring cut-out area 102, ensuring accurate cutting trajectory, improving processing accuracy and finished product qualification rate. At the same time, the double positioning and double locking design can meet the high-precision clamping requirements.

[0047] In this embodiment, the first screw 31 can sequentially pass through the first connecting hole 1011 and the first threaded hole 12 and be locked, allowing a portion of the inner ring cut-out area 101 to be cut by the cutting part, i.e., the locked portion is cut off. This rigid fixation of the portion of the inner ring cut-out area 101 to be cut off prevents wobbling or deformation during cutting due to lack of support, ensures precise machining of the cutting part along the predetermined contour, reduces dimensional deviations caused by clamping failure, and balances the cutting stress using the screw's preload, improving the machining accuracy of the inner ring cut-out area 101 and ensuring a high product qualification rate.

[0048] In this embodiment, the external thread direction of the second screw 32 is opposite to that of the first screw 31. The second screw 32 can pass through the second connecting hole 14 and the second threaded hole 1013 in sequence and be locked so that the remaining outer ring cutting area 102 can be cut by the cutting part, that is, the unlocked part is cut off. This design balances the clamping force through the reverse thread, avoids interference between the cutting tool and the screw during cutting, and ensures that the unlocked part to be cut is not obstructed by the screw during the cutting process, ensuring the accuracy of the cutting trajectory, improving processing safety and finished product accuracy.

[0049] like Figure 1 , Figure 5 and Figure 6As shown, the workpiece 100 also includes an annular finished product area 103. The inner ring of the annular finished product area 103 is connected to the inner ring cutting area 101, and the outer ring of the annular finished product area 103 is connected to the outer ring cutting area 102. The clamping assembly also includes a second clamping member 22, which is used to clamp the annular finished product area 103 onto the tooling table 1 so that the remaining part of the inner ring cutting area 101 can be cut off by the cutting member. When the remaining part of the inner ring cutting area 101 is cut off, the second clamping member 22 provides stable support for the annular finished product area 103, preventing it from deforming due to the stress generated by the inner ring cutting. This ensures that the position of the annular finished product area 103 is fixed during processing. Combined with the positioning and locking structure, the cutting member accurately cuts off the remaining part of the inner ring cutting area 101, improving the contour accuracy and surface quality of the annular finished product area 103 and ensuring the finished product qualification rate.

[0050] In summary, the clamping, positioning, and cutting process of workpiece 100 is roughly as follows:

[0051] (1) Place the workpiece 100 to be processed on the tooling table 1. The first positioning member passes through the first positioning hole 1021 of the outer ring cut-out area 102 and the second positioning hole 11 of the tooling table 1 to achieve initial positioning. Then, the first clamping member 21 is used to clamp the outer ring cut-out area 102. The first screw 31 is sequentially inserted into the first connecting hole 1011 of the inner ring cut-out area 101 and locked with the first threaded hole 12 of the tooling table 1. The locked portion of the inner ring cut-out area 101 and the portion of the outer ring cut-out area 102 are cut off.

[0052] (2) The second positioning member passes through the third positioning hole 1012 on the remaining inner ring cut area 101 and the fourth positioning hole 13 on the tooling table 1 to position the remaining workpiece 100 to be processed. The second screw 32 passes through the second connecting hole 14 on the tooling table 1 and the second threaded hole 1013 on the inner ring cut area 101 and locks it, and cuts off the remaining part of the outer ring cut area 102 that is not locked.

[0053] (3) Use the second clamping member 22 to clamp the annular finished product area 103, cut off the remaining part of the inner ring cut-out area 101, and retain the annular finished product area 103 as the finished product, thus completing the entire processing flow.

[0054] In step (1), the inner ring cut-out area 101 is composed of eight fan-shaped structures, retaining the central disk and eight connecting rods connected to the annular finished product area 103. This ensures the connection strength between the annular finished product area 103 and the central disk structure while accurately removing excess material, avoiding deformation of the annular finished product area 103 due to insufficient structural support during the cut-out process, ensuring the positional accuracy of the central disk and connecting rods, providing a stable foundation for subsequent processing, and improving the structural integrity and processing qualification rate of the finished product.

[0055] In other embodiments, the number of fan-shaped structures in the cut inner circle cut area 101 can be four, six, ten, etc., and is not specifically limited here. In other embodiments, the shape of the cut inner circle cut area 101 can also be multiple triangular structures, multiple rectangular structures, etc., and is not specifically limited here.

[0056] In this embodiment, the clamping assembly further includes a first adjusting bolt. The first clamping member 21 is connected to the tooling table 1 via the first adjusting bolt. The first adjusting bolt is used to adjust the distance between the first clamping member 21 and the tooling table 1. The distance between the first clamping member 21 and the tooling table 1 can be flexibly adjusted via the first adjusting bolt to accommodate outer ring cutting areas 102 of different thicknesses. This allows for precise control of the clamping force, preventing deformation of the workpiece 100 due to excessive pressure or displacement due to insufficient pressure. This improves the versatility and clamping stability of the clamping and positioning device, ensuring the positioning accuracy and processing quality of workpieces 100 of different specifications.

[0057] Similarly, the clamping assembly also includes a second adjusting bolt. The second clamping member 22 is connected to the tooling table 1 via the second adjusting bolt, which is used to adjust the distance between the second clamping member 22 and the tooling table 1. The distance between the second clamping member 22 and the tooling table 1 can be adjusted as needed via the second adjusting bolt to accommodate annular finished product areas 103 of different thicknesses. This avoids deformation of the annular finished product area 103 due to excessive clamping force, and also prevents displacement of the workpiece 100 due to insufficient pressure. At the same time, it can flexibly adapt to the clamping requirements of workpieces 100 of different specifications, improve the versatility of the clamping and positioning device, ensure that the annular finished product area 103 remains stable during processing, and guarantee cutting accuracy and finished product quality.

[0058] In this embodiment, the clamping and positioning device further includes a buffer pad, which is disposed on the surface of the fixture 1 facing the workpiece 100. During clamping, the elastic deformation of the buffer pad absorbs the clamping force, preventing surface indentations or deformation caused by direct hard contact between the fixture 1 and the workpiece 100, which is especially suitable for thin-walled parts or easily deformable materials. At the same time, the buffer pad can fill the small gap between the workpiece 100 and the fixture 1, enhance contact stability, reduce vibration during processing, improve the positioning accuracy and surface quality of the workpiece 100, and extend the service life of the fixture 1.

[0059] Optionally, the buffer pad can be a rubber pad, silicone pad, etc., which has good elasticity and wear resistance and can absorb the impact force through deformation when clamping the workpiece 100. No specific limitation is made here.

[0060] Figures 2-5As shown, the clamping and positioning device also includes a support component 4, which is connected to the fixture table 1 and is used to support the fixture table 1. The connection between the support component 4 and the fixture table 1 and the support component 4 can enhance the structural stability of the fixture table 1, prevent shaking or deformation due to force when clamping or cutting the workpiece 100, and ensure the positioning accuracy and processing quality of the workpiece 100.

[0061] Figures 2-5 As shown, the support assembly 4 includes a first support member 41 and multiple second support members 42. The first support member 41 is connected to the center of the fixture table 1, and the multiple second support members 42 are evenly distributed along the circumference of the fixture table 1. This forms a balanced support structure in both the center and circumference, effectively dispersing the clamping and cutting forces borne by the fixture table 1, preventing deformation or tilting of the fixture table 1 due to uneven local forces, ensuring that the fixture table 1 remains horizontal and stable, and providing a precise positioning reference for the workpiece 100 to be processed. At the same time, the evenly distributed support layout can adapt to workpieces 100 of different weights, improving the reliability of the clamping and positioning device structure and the stability of the processing process, ensuring positioning accuracy and finished product quality.

[0062] In this embodiment, there are four second support members 42. In other embodiments, the number of second support members 42 can be six, eight, etc., which can be adjusted according to the actual size of the tooling table 1. No specific limitation is made here.

[0063] In this embodiment, the heights of the first support member 41 and the multiple second support members 42 are all adjustable. Based on the clamping requirements of the workpiece 100, the levelness and height of the fixture table 1 are precisely adjusted to avoid positioning deviations of the workpiece 100 due to the tilt of the support surface. This not only adapts to different specifications of cut-off parts but also maintains stability through height compensation when the fixture table 1 is deformed under stress, ensuring the positional accuracy of the workpiece 100 during the cutting process. Simultaneously, it enhances the adaptability of the clamping and positioning device, improving processing reliability and finished product quality.

[0064] Optionally, the first support member 41 and the second support member 42 are double-layer cylindrical structures. The inner sleeve can move relative to the outer sleeve. The inner sleeve is connected to the tooling table 1, and the outer sleeve is in contact with the ground. When the inner sleeve is adjusted to a suitable position, the inner sleeve is fixedly connected to the outer sleeve by fasteners, which can ensure that the tooling table 1 is stably supported, avoid shaking during processing, maintain the positioning accuracy of the workpiece 100, and has a simple structure and is easy to operate, effectively improving processing stability and finished product quality.

[0065] In addition, a cylinder can be installed inside the first support member 41 and the second support member 42. The piston rod of the cylinder is connected to the tooling table 1. The piston rod can reciprocate relative to the cylinder body to drive the tooling table 1 to rise or fall. This can realize the rapid and precise adjustment of the height of the tooling table 1. The tooling table 1 can be flexibly raised and lowered according to the needs. Furthermore, the stable support of air pressure ensures the stable positioning of the workpiece 100, thereby improving processing efficiency and finished product accuracy.

[0066] In this embodiment, a level is provided on the tooling table 1, and scale lines are provided on the outer surfaces of the first support member 41 and the plurality of second support members 42. The level on the tooling table 1 can monitor the level of the table surface in real time, and the scale lines on the outer surfaces of the first support member 41 and the plurality of second support members 42 provide a precise reference for height adjustment. The two work together to quickly adjust the tooling table 1 to a horizontal position, ensuring accurate positioning of the workpiece 100, effectively avoiding processing errors caused by table tilt, and significantly improving processing accuracy and finished product qualification rate.

[0067] In this embodiment, both the bottom of the first support member 41 and the second support member 42 are provided with anti-slip layers. The anti-slip layers can increase the friction with the ground, prevent the tooling table 1 from shifting or shaking due to force during processing, ensure the stable positioning of the workpiece 100, enhance the reliability of the processing process, and guarantee processing accuracy and finished product quality.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
