[0018] By using the above-mentioned positioning device for stainless steel processing, when stainless steel door and window products are processed during the stainless steel processing process, when the stainless steel door and window products are positioned and fixed, the distance between the corner positioning assemblies at both sides can be adjusted by sliding the sliding seat of the spacing adjustment assembly along the adjustment groove and tightening the elastic pressing block at the adjustment groove by screwing the clamping stud, so that the corner positioning assemblies at both sides can position and fix the corner positions of stainless steel door and window products of different lateral widths, thereby realizing the positioning and fixation of stainless steel door and window products of different lateral widths and specifications, improving the adaptability of use, and at the same time, the pressure plate and the adjusting stud can be adjusted by the forward and reverse rotation of the adjusting stud.

Specifically, when performing the positioning and fixing operation on the stainless steel door and window products, first screw the clamping nuts on both sides close to the corresponding handles, and then respectively hold the handles to drive the adjusting studs to reverse counterclockwise. During the reversal process, the adjusting studs drive the pressure plate to expand the distance between it and the corresponding rear of the corner positioning box, until the distance between the back of the pressure plate and the rear of the corner positioning box can be lowered to the corner position of the stainless steel door and window products and then stop. , then hold the end head to drive the clamping stud to reverse counterclockwise so that the elastic pressure block rises and leaves the bottom of the adjusting groove, and then hold the end head to drive the slide seat to slide along the adjusting groove, and the corner positioning components immediately follow the sliding of the slide seat to adjust the spacing between each other. In this process, the stainless steel door and window products are placed upright between the corner positioning components at both sides. When the slide seat drives the corner positioning components to adjust the two side corners of the bottom of the stainless steel door and window products to be located between the corresponding rear part of the corner positioning box and the back side of the pressure plate, stop sliding the slide seat, and then keep the slide seat stationary and hold the end head to drive the clamping stud to rotate clockwise so that the elastic pressure blocks at the bottom are all pressed tightly against the corresponding adjusting grooves. The bottom is locked, so that the sliding seat cannot slide along the adjusting groove, thereby locking the position of the corner positioning assembly, and then the handle is held again to drive the adjusting stud to rotate clockwise. The adjusting stud drives the back of the pressure plate to approach the rear of the corresponding corner positioning box during the forward rotation, until the back of the pressure plate cooperates with the rear of the corresponding corner positioning box to position and press the corresponding corner position of the stainless steel door and window product. After the pressure plate presses and fixes the corresponding corner position of the stainless steel door and window product, the adjusting stud is kept from rotating and the clamping nut is tightened in front of the corresponding corner positioning box, so that the friction between the clamping nut and the front of the corner positioning box prevents the adjusting stud from rotating naturally.At the same time, the compression nut is used to tighten the threaded engagement degree of the adjusting stud and the corner positioning box to further prevent the adjusting stud from rotating naturally. In this way, the corresponding corner position of the stainless steel door and window product can be quickly positioned and fixed by turning the adjusting stud to drive the pressure plate close to the rear of the corner positioning box. At the same time, the positioning and fixing of the corresponding corner position of the stainless steel door and window product can be released by turning the adjusting stud to drive the pressure plate away from the rear of the corner positioning box. The positioning, fixing and releasing methods of the corner positions of stainless steel door and window products are simple and easy to operate, which is convenient for the stainless steel door and window products to be quickly positioned and fixed for processing. At the same time, it is convenient to release and remove the stainless steel door and window products in time when the processing operation is completed. At the same time, in the process of positioning and fixing the stainless steel door and window products, the lower parts of the end surfaces of the pressure plates at both sides are fixed with the extension plates extending laterally, and the extension plates and the corresponding pressure plates form L-shaped plates. Therefore, the positioning and clamping area of ​​the corresponding corner positions of the stainless steel door and window products can be increased through the arrangement of the extension plates, thereby improving the stability and reliability of the positioning and fixing of the stainless steel door and window products. In addition, the limiting support assembly is installed in the middle of the top surface of the top plate, so that the stainless steel door and window products can be positioned against the positioning support plate of the limiting support assembly. The method can provide reliable back support for the middle part of the stainless steel door and window product, and at the same time, the method of supporting the bottom surface of the stainless steel door and window product by the pad at the bottom of the limiting support assembly can stably position and support the bottom position of the stainless steel door and window product, which not only improves the vertical stability of the stainless steel door and window product during the positioning and fixing process, but also facilitates the stainless steel door and window product to quickly compare horizontally with the corner positioning assemblies on both sides. Then, the stainless steel door and window product that has been positioned and fixed in the vertical state can be processed. During the processing, when it is necessary to switch and adjust the processing surface of the stainless steel door and window product, the locking nut is screwed up close to the top plate, and then The processing surface of the stainless steel door and window products can be quickly switched and adjusted by driving the top plate to rotate horizontally through the support studs, so that the processing surface of the stainless steel door and window products can be rotated and adjusted to face the operator for processing. At the same time, after the adjustment is completed, the locking nut is tightened and pressed against the top surface of the U-shaped seat, so that the top plate can be locked and cannot continue to rotate horizontally with the help of the friction between the locking nut and the top surface of the U-shaped seat. The switching and adjustment method of the processing surface of the stainless steel door and window products is simple and easy to operate, which is convenient for fast switching and adjustment of the processing surface of the stainless steel door and window products, and there is no need to loosen, turn over and reposition the stainless steel door and window products.

[0020] 2. The distance between the pressure plate and the rear of the corner positioning box can be adjusted by adjusting the studs in the forward and reverse directions, so that the corner positioning components on both sides can position and fix the corners of stainless steel door and window products of different thicknesses and sizes, thus realizing the positioning and fixing of stainless steel door and window products of different thicknesses and sizes, and further improving the adaptability of use;

[0021] 3. By turning the adjusting stud to drive the pressing plate close to the rear of the corner positioning box, the corresponding corner position of the stainless steel door and window product can be quickly positioned and fixed. At the same time, by turning the adjusting stud to drive the pressing plate away from the rear of the corner positioning box, the positioning and fixing of the corresponding corner position of the stainless steel door and window product can be released.

[0043] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, both sides of the top surface of the top plate 2 are installed with spacing adjustment components 3 that can be adjusted and locked by lateral sliding. Specifically, the spacing adjustment components 3 include adjustment grooves 301 and slide seats 302.

[0044] See also Figure 1 , Figure 3 , Figure 6and Figure 7 As shown, the tops of the spacing adjustment components 3 at the two side positions are installed with corner positioning components 5 for positioning and fixing the corner positions of the stainless steel door and window products on both sides in the upright state. Specifically, the corner positioning components 5 include corner positioning boxes 501 and adjusting studs 508. The top surfaces of the slide seats 302 at the two side positions are fixed with corner positioning boxes 501 at positions close to each other. The corner positioning boxes 501 are all rectangular hollow boxes, and the end surfaces and top surfaces of the corner positioning boxes 501 at the two side positions relative to each other are open. The front parts of the corner positioning boxes 501 at the two side positions are longitudinally meshed and interspersed with adjusting studs 508, and the rear ends of the adjusting studs 508 extending into the corresponding corner positioning boxes 501 are coaxially rotatably connected with bearing seats 505, and the back sides of the bearing seats 505 are vertically fixed with pressing plates 503 in the horizontal direction, and the pressing plates 503 and the rear ends of the corresponding corner positioning boxes 501 are fixed with adjusting studs 508 in the horizontal direction. Comparing the front and back parts, the part of the adjusting stud 508 extending out of the front of the corresponding corner positioning box 501 is coaxially engaged with a locking nut 507.

At the same time, the corresponding corner positions of the stainless steel door and window products can be quickly positioned and fixed by turning the adjusting stud 508 to drive the pressure plate 503 close to the rear portion of the corner positioning box 501, and the positioning and fixing of the corresponding corner positions of the stainless steel door and window products can be released by turning the adjusting stud 508 to drive the pressure plate 503 away from the rear portion of the corner positioning box 501, thereby conveniently completing the positioning and fixing of the corner positions of the stainless steel door and window products and releasing and loosening them.

[0045] See also Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, a limiting support assembly 1 is installed in the middle of the top surface of the top plate 2 for back support and elevation support of the lower middle section of the stainless steel door and window product in an upright state. Specifically, the limiting support assembly 1 includes a pad 103 and a positioning pad 101. The pad 103 is horizontally fixed in the middle of the top surface of the top plate 2 for elevation support of the bottom surface of the lower middle section of the stainless steel door and window product. A positioning pad 101 is vertically fixed in the rear part of the top surface of the pad 103 for back support of the back of the lower middle section of the stainless steel door and window product.

[0046] See also Figure 4-Figure 7 As shown, the spacing adjustment component 3 is optimized as follows. Specifically, the adjustment grooves 301 are all dovetail grooves or I-shaped grooves, and the top surface of the slide 302 is not lower than the top of the corresponding adjustment groove 301. The purpose of this arrangement is, first of all, to facilitate the slide 302 to only slide and adjust horizontally along the adjustment groove 301 and cannot escape from other directions. At the same time, it is also convenient for the corner positioning box 501 placed on the top surface of the slide 302 to not interfere with the surface of the top plate 2. The top of the clamping stud 304 is coaxially fixed with an end head 303 for easy holding, and the elastic clamping block 306 is a cylindrical rubber block with an outer diameter no larger than the outer diameter of the clamping stud 304. This arrangement makes it easy to turn the clamping stud 304 forward and reverse by holding the end head 303, and at the same time, the friction force when the elastic clamping block 306 is pressed on the bottom of the adjusting groove 301 can prevent the slide groove from sliding along the adjusting groove 301, and the elastic buffering capacity of the elastic clamping block 306 can also prevent damage to the bottom surface of the adjusting groove 301.

[0047] See also Figure 1-Figure 9 As shown, the rotation adjustment component 6 and the corner positioning component 5 are optimized as follows: first, the clamping nut 507 of the corner positioning component 5 and the locking nut 603 of the rotation adjustment component 6 are both hand-tightened knurled nuts, so that the clamping nut 507 and the locking nut 603 can be smoothly tightened and loosened by directly tightening by hand. At the same time, in the corner positioning component 5, the front end of the adjustment stud 508 is fixedly installed with a handle 509 for easy hand holding. The reason for this arrangement is to facilitate the adjustment stud 508 to be directly driven to rotate forward and reverse by holding the handle 509 and applying force. Guide holes 504 are longitudinally opened at the front of the corner positioning box 501 at the upper and lower positions corresponding to the adjusting studs 508, and guide posts 506 are inserted into the guide holes 504 for coaxial sliding in the longitudinal direction, and the rear ends of the guide posts 506 are fixed in front of the corresponding pressure plates 503. Preferably, the length of the guide posts 506 is not less than the length of the adjusting studs 508, and the outer peripheries do not interfere with the clamping nuts 507 and the handles 509. Such an arrangement makes it easy for the pressure plate 503 to move forward or backward with the adjusting studs 508, and the guide posts 506 can slide longitudinally along the guide holes 504 to guide and correct the forward or backward movement of the pressure plate 503, thereby preventing the pressure plate 503 from being dislocated due to the rotation of the adjusting studs 508.

[0048] In a more preferred scheme, the lower parts of the end surfaces of the pressure plates 503 at both sides are fixed with extension plates 5010 extending laterally to increase the positioning and clamping area of ​​the corners of the stainless steel door and window products. The extension plates 5010 and the corresponding pressure plates 503 form L-shaped plates, and the directions of the pressure plates 503 and the extension plates 5010 at both sides are respectively consistent with the directions of the corresponding corners of the stainless steel door and window products. Such an arrangement makes it easy to increase the positioning and clamping area of ​​the corresponding corners of the stainless steel door and window products through the arrangement of the extension plates 5010, thereby improving the degree of reliability of the positioning and fixing of the corners of the stainless steel door and window products. At the same time, the rear front of the corner positioning box 501 and the back of the pressure plate 503 and the extension plate 5010 are covered with a buffer lining 502 fixed with a buffer material. Preferably, the buffer lining 502 is a rubber plate. Such a configuration facilitates the direct contact of the buffer lining 502 with the surface of the corner position of the stainless steel door and window product to achieve a good elastic buffering effect, thereby preventing the surface of the corner position of the stainless steel door and window product from being damaged during the process of positioning and fixing the corner position of the stainless steel door and window product.

[0049] See also Figure 3 , Figure 8 and Fig. 9 As shown, the limiting support assembly 1 is optimized as follows: the top surface of the pad 103 is not lower than the bottom top surface of the corner positioning box 501. Preferably, the top surface of the pad 103 is flush with the bottom top surface of the corner positioning box 501, so that after the stainless steel door and window product is placed upright and supported on the top surface of the pad 103, the bottom surfaces of the corners on both sides of the bottom of the stainless steel door and window product can be limited and flush with the corresponding bottom top surface of the corner positioning box 501. At the same time, the front of the positioning support plate 101 is flush with the front of the rear part of the corner positioning box 501, and the front of the positioning support plate 101 is covered with a buffer back plate 102 fixed with a buffer material. Preferably, the buffer back plate 102 is a rubber plate and the front is flush with the front of the buffer lining plate 502. Such a configuration facilitates elastic buffering of the back of the bottom middle section of the stainless steel door and window product through the configuration of the buffer back plate 102.

[0050] By adopting the above structure, when stainless steel door and window products are processed during the stainless steel processing process, when the stainless steel door and window products are positioned and fixed, the distance between the corner positioning components 5 at the two sides can be adjusted by sliding the sliding seat 302 of the spacing adjustment component 3 along the adjustment groove 301 and tightening the elastic pressing block 306 in the adjustment groove 301 by screwing the clamping stud 304, and then the corner positioning components 5 at the two sides can be positioned and fixed to the corner positions of stainless steel door and window products with different lateral widths, thereby realizing the positioning and fixing of stainless steel door and window products with different lateral widths and specifications, and improving the adaptability of use. At the same time, the pressure plate 503 and the corner positioning box can be adjusted by adjusting the stud 508 in the forward and reverse directions. 501, and then the corner positioning components 5 on both sides can position and fix the corner positions of stainless steel door and window products of different thicknesses, thereby realizing the positioning and fixation of stainless steel door and window products of different thicknesses and specifications, and further improving the adaptability of use. Specifically, when positioning and fixing the stainless steel door and window products, first screw the clamping nuts 507 on both sides close to the corresponding handles 509, and then hold the handles 509 respectively to drive the adjusting studs 508 to reverse counterclockwise. During the reversal process, the adjusting studs 508 drive the pressure plate 503 to expand the distance between it and the rear of the corresponding corner positioning box 501, until the distance between the back of the pressure plate 503 and the rear of the corner positioning box 501 can put down the stainless steel door and window products. After the corner position is reached, the slide 302 is stopped after being moved, and then the end head 303 is held to drive the clamping stud 304 to reverse counterclockwise so that the elastic pressing block 306 rises and leaves the bottom of the adjusting groove 301. Then the end head 303 can be held to drive the slide 302 to slide along the adjusting groove 301, and the corner positioning assembly 5 immediately follows the slide 302 to slide and adjust the distance between each other. In this process, the stainless steel door and window product is placed upright between the corner positioning assemblies 5 at the two side positions. When the slide 302 drives the corner positioning assembly 5 to adjust the two side corners of the bottom of the stainless steel door and window product to be located between the rear of the corresponding corner positioning box 501 and the back of the pressure plate 503, the slide 302 is stopped, and then the slide 302 is kept stationary and the end head 303 is held to drive the clamping stud 304 to rotate clockwise. The elastic pressing blocks 306 at the bottom are pressed tightly against the bottom of the corresponding adjusting grooves 301, so as to lock the sliding seat 302 from sliding along the adjusting grooves 301, thereby locking the position of the corner positioning assembly 5, and then respectively holding the handles 509 to drive the adjusting studs 508 to rotate clockwise. During the forward rotation, the adjusting studs 508 drive the back of the pressing plate 503 to approach the rear of the corresponding corner positioning box 501, until the back of the pressing plate 503 cooperates with the rear of the corresponding corner positioning box 501 to position and press the corresponding corner position of the stainless steel door and window product. After the pressing plate 503 presses and fixes the corresponding corner position of the stainless steel door and window product, keep the adjusting studs 508 from rotating and tighten the clamping nuts 507 in front of the corresponding corner positioning box 501.In this way, the friction between the clamping nut 507 and the front of the corner positioning box 501 can be used to prevent the adjusting stud 508 from rotating naturally. At the same time, the clamping nut 507 is used to tighten the threaded engagement degree of the adjusting stud 508 and the corner positioning box 501 to further prevent the adjusting stud 508 from rotating naturally. In this way, the corresponding corner position of the stainless steel door and window product can be quickly positioned and fixed by turning the adjusting stud 508 to drive the pressure plate 503 close to the rear of the corner positioning box 501. At the same time, the positioning and fixation of the corresponding corner position of the stainless steel door and window product can be released by turning the adjusting stud 508 to drive the pressure plate 503 away from the rear of the corner positioning box 501, thereby fixing the corner position of the stainless steel door and window product. The release and unlocking methods are simple and easy to operate, which is convenient for quickly positioning and fixing the stainless steel door and window products for processing operations, and is also convenient for timely release and removal when the processing operations of the stainless steel door and window products are completed. At the same time, in the process of positioning and fixing the stainless steel door and window products, the lower parts of the end surfaces of the pressure plates 503 at the two sides are fixed with extension plates 5010 extending horizontally, and the extension plates 5010 and the corresponding pressure plates 503 form L-shaped plates. Therefore, the positioning and clamping area of ​​the corresponding corner positions of the stainless steel door and window products can be increased through the arrangement of the extension plates 5010, thereby improving the stability and reliability of the positioning and fixing of the stainless steel door and window products. In addition, since the limited support component 1 is installed in the middle of the top surface of the top plate 2, By means of the stainless steel door and window product leaning against the positioning support plate 101 of the limiting support assembly 1, the middle part of the stainless steel door and window product can be reliably supported by the backing plate 101, and at the same time, by means of the pad 103 at the bottom of the limiting support assembly 1 supporting the bottom surface of the stainless steel door and window product, the bottom position of the stainless steel door and window product can be stably positioned and supported, which not only improves the vertical stability of the stainless steel door and window product during the positioning and fixing process, but also facilitates the stainless steel door and window product to be quickly horizontally compared with the corner positioning assemblies 5 on both sides, and then the stainless steel door and window product that has been positioned and fixed in the vertical state can be processed. In the process of processing, when it is necessary to switch and adjust the processing surface of the stainless steel door and window product, the upper screw lock The tightening nut 603 is close to the top plate 2, and then the top plate 2 is driven to rotate horizontally by the support stud 604, so that the processing surface of the stainless steel door and window products can be quickly switched and adjusted, which is convenient for rotating and adjusting the processing surface of the stainless steel door and window products to face the operator for processing. At the same time, after the adjustment is completed, the locking nut 603 is tightened and pressed against the top surface of the U-shaped seat 601, so that the top plate 2 can be locked and cannot continue to rotate horizontally with the help of the friction between the locking nut 603 and the top surface of the U-shaped seat 601. The switching and adjustment method of the processing surface of the stainless steel door and window products is simple and easy to operate, which is convenient for quickly switching and adjusting the processing surface of the stainless steel door and window products, and there is no need to loosen, turn over and reposition the stainless steel door and window products.
