[0002] At present, doors and windows are one of the important external protective structures of buildings, which play the functions of wind and rain protection, heat insulation, sound insulation, lighting, ventilation, etc. With the improvement of people's living standards, the requirements for doors and windows in decoration are getting higher and higher. When doors and windows are produced, cutting machines are used to cut their frames.

[0003] Among them, when cutting stainless steel door and window frames in the market, most of them are still used by operators to hold the stainless steel door and window frames, place them on the workbench, push the stainless steel door and window frames to one side of the cutting machine, and cut them.

[0004] During such a cutting process, the vibration caused by the contact between the cutting blade and the stainless steel door and window frame will make it difficult for the operator to fix the stainless steel door and window frame, resulting in cutting deviation. For this reason, a new technical solution needs to be designed to ensure that the stainless steel door and window frame is firmly positioned during the cutting process. Utility Model Content

[0005] The utility model aims to provide a cutting and positioning fixture for a stainless steel door and window frame, which solves the problems raised in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a stainless steel door and window frame cutting and positioning fixture, comprising a processing table, a moving groove is opened in the middle of the processing table, a moving frame is slidably installed in the moving groove, a positioning frame is fixedly installed on the top of the moving frame, and positioning cylinders are fixedly installed at the four corners of the top of the positioning frame, and a positioning mechanism is installed in each group of the positioning cylinders;

[0007] The positioning mechanism includes a piston groove opened at the bottom of the inner cavity of the positioning cylinder, an extrusion block movably installed in the piston groove, adjustment grooves opened on both sides of the positioning cylinder, wedge blocks movably installed in the two groups of adjustment grooves, and arc heads fixedly installed on the other sides of the two groups of wedge blocks, the two groups of wedge blocks respectively fit with the two sides of the extrusion block, and the two groups of adjustment grooves are interconnected with the inner cavity of the positioning cylinder.

[0008] As an optional solution of the technical solution of the present application, each group of the wedge-shaped blocks has a spring fixedly installed on the side wall, and the other side of each group of the springs is fixedly installed on the inner cavity of the positioning tube, so as to support the wedge-shaped blocks.

[0009] As an optional solution of the technical solution of the present application, a nut is welded on the top of each group of the positioning cylinders, a bolt is threadedly connected inside each group of the nuts, and multiple groups of the bolts are rotatably installed on the top of each group of extrusion blocks respectively, so that the extrusion blocks can be adjusted.

[0010] As an optional solution of the technical solution of the present application, a sleeve is sleeved on the top of each group of the positioning cylinders, and a clamping block is fixedly installed on the side wall of each group of the sleeves, which can clamp the stainless steel door and window frames.

[0011] As an optional solution to the technical solution of the present application, a drive box is fixedly installed on the bottom of the processing table, a screw is installed on the internal thread of the drive box, a moving block is installed on the internal thread of the screw, and the top of the moving block is fixedly installed on the bottom of the moving frame, which can drive the moving block to move left and right.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application continuously squeezes the extrusion block in the positioning mechanism by tightening the bolt in the nut. As the extrusion block continuously moves into the piston groove, it continuously squeezes the wedge blocks on both sides, causing the two groups of wedge blocks to move outward along the adjustment groove, ensuring that the arc-shaped head located on the outside of the wedge block firmly supports the inner wall of the sleeve, and the four groups of clamps are firmly fixed on one side of the four groups of positioning cylinders, effectively clamping and positioning stainless steel door and window frames of different thicknesses, widths and lengths.

[0015] 2. The technical solution of the present application is that a screw is installed on the inner thread of the driving box, and a moving block is installed on the inner thread of the screw. When the stainless steel door and window frame is positioned on the positioning frame, the motor can be driven to drive the screw to rotate, so that the screw drives the moving block to rotate, and cooperates with the limit groove opened on one side of the driving box to ensure that the moving block can drive the positioning frame to move horizontally left and right, so that the stainless steel door and window frame on the positioning frame is automatically moved to one side of the cutting machine, avoiding time-consuming and labor-intensive manual pushing of the stainless steel door and window frame.

[0022] The positioning mechanism includes a piston groove 21 opened at the bottom of the inner cavity of the positioning cylinder 2, an extrusion block 22 movably installed in the piston groove 21, adjustment grooves 23 opened on both sides of the positioning cylinder 2, wedge blocks 24 movably installed in the two groups of adjustment grooves 23, and arc heads 25 fixedly installed on the other sides of the two groups of wedge blocks 24. The two groups of wedge blocks 24 are respectively matched with the two sides of the extrusion block 22, and the two groups of adjustment grooves 23 are connected with the inner cavity of the positioning cylinder 2.

[0023] In this technical solution, by tightening the bolt 31 in the nut 3, the extrusion block 22 in the positioning mechanism is continuously squeezed. As the extrusion block 22 continues to move into the piston groove 21, the wedge blocks 24 on both sides are continuously squeezed, so that the two groups of wedge blocks 24 move outward along the adjustment groove 23, ensuring that the arc head 25 located on the outside of the wedge block 24 firmly supports the inner wall of the sleeve 32, and the four groups of clamps are firmly fixed on one side of the four groups of positioning tubes 2, effectively clamping and positioning stainless steel door and window frames of different thicknesses, widths and lengths.

[0024] In some technical solutions, a drive box 4 is fixedly installed at the bottom of the processing table 1, a screw 41 is installed on the internal thread of the drive box 4, a moving block 42 is installed on the internal thread of the screw 41, the top of the moving block 42 is fixedly installed on the bottom of the moving frame 12, and can drive the moving block 42 to move left and right, a motor 43 is fixedly installed on the side wall of the drive box 4, the drive output end of the motor 43 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one side of the screw 41, and a limiting groove is provided at the bottom of the side wall of the drive box 4, and the limiting groove is slidably connected to the moving block 42, so that the moving block 42 can be limited.

[0025] In this technical solution, a screw 41 is installed through the internal thread of the driving box 4, and a moving block 42 is installed on the internal thread of the screw 41. When the stainless steel door and window frame is positioned on the positioning frame 13, the motor 43 can be driven to drive the screw 41 to rotate, so that the screw 41 drives the moving block 42 to rotate, and cooperates with the limiting groove opened on one side of the inner side of the driving box 4 to ensure that the moving block 42 can drive the positioning frame 13 to move horizontally left and right, so that the stainless steel door and window frame on the positioning frame 13 is automatically moved to one side of the cutting machine, avoiding time-consuming and laborious manual pushing of the stainless steel door and window frame.

[0026] In some technical solutions, a nut 3 is welded on the top of each group of positioning cylinders 2, and a bolt 31 is threadedly connected inside each group of nuts 3. Multiple groups of bolts 31 are rotatably installed on the top of each group of extrusion blocks 22, so that the extrusion blocks 22 can be adjusted.

[0031] In this technical solution, when the sleeve 32 is preferentially sleeved on the outside of the positioning tube 2, the spring 26 installed on one side of the wedge block 24 can support the arc head 25 on one side of the wedge block 24 to position the sleeve 32 on the outside of the positioning tube 2.

[0033] When in use, first place the stainless steel door and window frame to be cut on the positioning frame 13, and successively sleeve the sleeve 32 on the four groups of positioning cylinders 2, so that the clamping blocks 33 installed on the side walls of the four groups of positioning cylinders 2 are tightly fitted on the top of the stainless steel door and window frame, and at the same time, the bolts 31 in the nuts 3 are tightened to continuously squeeze the extrusion blocks 22 in the positioning mechanism. As the extrusion blocks 22 continuously move into the piston groove 21, they will continuously squeeze the wedge blocks 24 on both sides, so that the two groups of wedge blocks 24 move outward along the adjustment groove 23, ensuring that the arc-shaped heads 25 on the outside of the wedge blocks 24 firmly support the inner wall of the sleeve 32, and the four groups of clamps are firmly fixed on the four groups. On one side of the positioning cylinder 2, stainless steel door and window frames of different thicknesses, widths and lengths can be effectively clamped and positioned. At the same time, a screw 41 is installed through the internal thread of the drive box 4, and a moving block 42 is installed on the internal thread of the screw 41. When the stainless steel door and window frame is positioned on the positioning frame 13, the motor 43 can be driven to drive the screw 41 to rotate, so that the screw 41 drives the moving block 42 to rotate, and cooperates with the limit groove opened on one side of the inner side of the drive box 4 to ensure that the moving block 42 can drive the positioning frame 13 to move horizontally left and right, so that the stainless steel door and window frame on the positioning frame 13 is automatically moved to the side of the cutting machine, avoiding time-consuming and labor-intensive manual pushing of the stainless steel door and window frame.
