[0038] See also Figure 1 - Fig. 9 A fixing device for sheet metal processing includes a sheet metal fixing platform 1 on which a fixing plate 2 having the same width as the sheet metal and which is adjustable is provided for fixing, a fixing surface of the fixing plate 2 is provided with multiple groups of stabilizing layers 201, and an upper clamping plate 3 which can move up and down is provided on the fixing plate 2 for clamping.

[0039] See also Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 7 The fixing device for sheet metal processing of the present application mainly processes and fixes sheet metal parts through the fixing plate 2 and the upper clamping plate 3 arranged on the sheet metal fixing platform 1, wherein the fixing plate 2 can be adjusted on the sheet metal fixing platform 1, and is used to directly push the sheet metal part to the outer wall of the fixing plate 2 for fixing. The side of the fixing plate 2 in contact with the sheet metal is provided with two sets of stabilizing layers 201, which are respectively arranged on both sides of the fixing surface, and are used to contact the sheet metal. The stabilizing layer 201 is made of magnetic material. When the sheet metal has magnetism, it can tightly adsorb the contact surface to prevent the problem of loose fit when it is against the outer wall of the fixing plate 2. At the same time, an upper clamping plate 3 extending toward the sheet metal part is provided at the end of the fixing plate 2 against which the sheet metal is leaned, and the upper clamping plate 3 is arranged to move up and down on the fixing plate 2, so that when the sheet metal is fixed, the distance between the upper clamping plate 3 and the sheet metal can be adjusted to fix its upper end surface, thereby ensuring the flexibility of the sheet metal fixation, and avoiding the problem of unfixed point offset caused by the use of fasteners for fixing. It is suitable for more sheet metal fixing needs and is also convenient to operate.

[0040] In some embodiments, the present application provides a slot in the middle of the inner end of the sheet metal fixing platform 1, and a threaded rotating rod 7 is movably installed in the slot through a bearing, so that the fixing plate 2 can be located above the threaded section of the threaded rotating rod 7, and the front and rear fixed positions of the fixing plate 2 on the sheet metal fixing platform 1 are adjusted by rotating the handle of the threaded rotating rod 7. The fixing plate 2 and the threaded rotating rod 7 are connected by a sleeve 701, so that one end of the sleeve 701 can be threadedly connected to the threaded section set on the threaded rotating rod 7 for movement, and the other end is installed on the outer end surface of the fixing plate 2 through a fixing structure. After the connection, by rotating the handle of the threaded rotating rod 7 to drive it to move inside the slot of the sheet metal fixing platform 1, the sleeve 701 is also relatively moved forward and backward in the threaded section of the threaded rotating rod 7 to adjust the fixed position.

[0041] Among them, the fixing structure includes a connecting plate 702 and a limiting frame 703, wherein one end of the connecting plate 702 is installed on the top of the sleeve 701 and extends from the slot provided in the sheet metal fixing platform 1, and contacts with the non-fixed side of the fixing plate 2, and the limiting frame 703 is installed at the lower end of the non-fixed side of the fixing plate 2, so that one end of the connecting plate 702 extending from the slot can be inserted therein to position the connection. After plugging in, the connecting plate 702 and the limiting frame 703 are horizontally plugged in by a latch to complete the fixation between the fixing plate 2 and the connecting plate 702. In this way, it is also convenient for the subsequent disassembly and assembly of the fixing plate 2, and replacement according to the use requirements. In the present application, the fixing plate 2 is set to be the same width as the sheet metal fixing platform 1, so that the sheet metal can be placed on the fixing plate 2 to the greatest extent to ensure the application effect.

[0042] It should also be noted that when the sheet metal surface is large, the position of the fixing plate 2 on the sheet metal fixing table 1 can be adjusted so that the sheet metal can be completely placed on the sheet metal fixing table 1 for processing. When it is small, the position of the fixing plate 2 can also be relatively adjusted so that the sheet metal can be placed forward when it is on the sheet metal fixing table 1, making it easier for the operator to process it.

[0043] See also Figure 2 , Figure 5 and Figure 6 In the present application, an anti-skid pad 301 is also provided. A groove is provided at the bottom of the upper splint 3 to allow one end of the anti-skid pad 301 to be stuck therein. This design facilitates the subsequent disassembly and assembly of the anti-skid pad 301, wherein the other end of the anti-skid pad 301 protrudes from the inside of the groove and is provided with an anti-skid pattern on the side in contact with the upper end surface of the sheet metal. The anti-skid pad 301 is made of rubber and has anti-skid patterns. When fixing the upper end surface of the sheet metal, the friction of the contact surface can be increased, making the connection more stable while preventing problems such as slipping.

[0044] See also Figure 3 , Figure 4 , Figure 6 and Fig. 9 The present application also provides a movable sleeve 4, an extrusion spring 401, an internal groove 5 and an inner screw 501, wherein the internal groove 5 is opened in the middle of the inner end of the fixed plate 2, so that the inner screw 501 is vertically fixed therein, and the movable sleeve 4 is sleeved on the outside of the inner screw 501 and can move up and down along the outside thereof, and the extrusion spring 401 arranged between the movable sleeve 4 and the internal groove 5 can surround the inner screw 501, and then by moving the movable sleeve 4 up and down, the extrusion spring 401 can be squeezed or stretched, wherein one end of the movable sleeve 4 can extend out of the internal groove 5 and be connected to the fixed plate 2 through a connecting structure. Therefore, only by moving the fixed plate 2 up and down, the movable sleeve 4 can be driven to move in the same direction with it, and the extrusion spring 401 can be squeezed or stretched, thereby adjusting the fixed distance from the fixed plate 2 to the upper end surface of the sheet metal according to the thickness of the sheet metal, and by the elastic force of the extrusion spring 401 itself, the sheet metal can be clamped between the fixed plate 2 and the sheet metal fixing platform 1, thereby improving the flexibility during fixing.

[0045] It should also be noted that the connection structure mainly includes a fixed splint 9, wherein the fixed splint 9 is installed at one end of the movable sleeve 4 and can extend out of the built-in groove 5. After clamping the side of the upper splint 3, it is penetrated by bolts through the upper splint 3, and a threaded connection is made between the two to facilitate the subsequent disassembly and assembly of the upper splint 3.

[0046] Among them, a positioning pressing cylinder 6 is provided with a threaded sleeve on the upper part of the positioning pressing cylinder 6, which is used for pressing the movable sleeve 4 to move it up and down after the positioning pressing cylinder 6 is rotated, thereby squeezing the extrusion spring 401, so that the elastic force generated by the extrusion spring 401 changes, and its elastic force is adjusted according to the fixing requirements of the sheet metal, so that the sheet metal workpiece can be clamped between the fixed plate 2 and the sheet metal fixing platform 1, ensuring flexible use while also improving stability; the bottom of the movable sleeve 4 pressed out of the positioning pressing cylinder 6 is connected with a clamping cylinder 601, wherein the clamping cylinder 601 can be inserted into the opening of the movable sleeve 4, so that it is fitted with the inner wall of the opening of the movable sleeve 4, and when the movable sleeve 4 is squeezed downward, the stability of the connection can be improved to prevent displacement.

[0047] See also Figure 2 , Figure 3 , Figure 4 and Figure 8 In the present application, a clamping member 801 and a positioning surface 802 are also provided. The clamping member 801 is provided around the sheet metal fixing platform 1, and is constructed in a bent state so that its bottom can contact the surface of the area where the sheet metal fixing platform 1 is placed. At the same time, the inner end surface can be fitted with the outer wall of one side of the sheet metal fixing platform 1. For some needs to move the sheet metal fixing platform 1 as a whole and then fix it, it is only necessary to stretch the positioning spring 803 and fix it around the placement area. The sheet metal fixing platform 1 is provided with external movable holes 8 around it, which are used to connect the external movable holes 8 with the clamping member 801, so as to facilitate the subsequent stretching of the clamping member 801 according to the needs of the placement area, and clamp the sheet metal fixing platform 1 in the placement area after adjusting the distance of the clamping member 801, which is convenient for After the sheet metal fixing platform 1 is displaced, the positioning surface 802 is set on the clamping surface of the clamping member 801, which is made of rubber material and can increase the friction of the contact surface during the clamping process. When it is difficult to fix, a matching card insertion rod 804 is installed at one end of the clamping member 801 close to the outer movable hole 8. At this time, one end of the positioning spring 803 is installed on the inner wall of the outer movable hole 8, and the other end is installed on the card insertion rod 804, and the card insertion rod 804 is pushed to the inside of the opening of the outer movable hole 8.
