A slide cylinder is slidably connected inside the base plate, and a clamping rod is slidably connected inside the slide cylinder. A spring is installed inside the slide cylinder. The motor drives the turntable to rotate, which in turn causes the guide rail to move the slide rod, which in turn causes the slide cylinder to move the clamping rod. This allows the clamping rod to move and clamp the louvers, making it easy to position the louvers. Furthermore, by rotating the screw and the slide cylinder to perform a threaded movement, the device can easily clamp and fix louvers with different aspect ratios.

[0007] Preferably, a screw is threadedly connected to the inside of the slide cylinder, and the screw and the slide rod are connected by a bearing. The distance between the slide cylinder and the slide rod is controlled by the screw.

[0011] Preferably, one end of the compression spring is fixedly connected to the hanging plate, and the other end of the compression spring is fixedly connected to the pressure plate. By setting the compression spring, the pressure plate can be reset.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a turntable to rotate, which in turn causes the guide rail to move the slide rod, which in turn causes the slide cylinder to move the clamping rod, allowing the clamping rod to move and clamp the louvers, making the louvers easy to position. Furthermore, by rotating the screw and the slide cylinder to make a threaded movement, the device can easily clamp and fix louvers with different aspect ratios.

[0014] 2. This utility model uses a spring to act on the pressure plate, allowing the pressure plate to slide on the outside of the cutter. This prevents material from jumping out after the cutter is separated from the louver. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 A louver processing positioning fixture includes a base plate 1, a motor 2 fixedly installed at the lower middle of the base plate 1, a clamping mechanism 3 provided on the rotating shaft of the motor 2, a bracket 4 fixedly connected to the upper end of the base plate 1, a cylinder 5 fixedly installed at the upper middle of the bracket 4, the cylinder rod of the cylinder 5 passing through the bracket 4 and slidably connected to the bracket 4, a cutting mechanism 6 provided on the cylinder rod of the cylinder 5, and a cutting edge 7 opened in the middle of the base plate 1.

[0022] Please see Figure 2The clamping mechanism 3 includes a turntable 31, which is fixedly connected to the rotating shaft of the motor 2. A guide rail 32 is fixedly connected to the surface of the turntable 31, and a slide rod 33 is slidably connected inside the guide rail 32. A slide cylinder 34 is slidably connected inside the base plate 1, and a screw 35 is threadedly connected inside the slide cylinder 34. The screw 35 and the slide rod 33 are connected by bearings. The distance between the slide cylinder 34 and the slide rod 33 is controlled by the screw 35. A sliding plate 36 is fixedly connected to the surface of the slide cylinder 34 and is slidably connected to the base plate 1. The sliding plate 36 guides the movement of the slide cylinder 34. The slide cylinder 34 is slidably connected inside the base plate 1. The device includes a clamping rod 37 and a spring 38 inside the slide cylinder 34. One end of the spring 38 is fixedly connected to the slide cylinder 34, and the other end is fixedly connected to the clamping rod 37. By setting the spring 38, the clamping rod 37 can be easily reset. The motor 2 drives the turntable 31 to rotate, which in turn causes the guide rail 32 to move the slide rod 33, which in turn causes the slide cylinder 34 to move the clamping rod 37. This allows the clamping rod 37 to move and clamp the louvers, making it easy to position the louvers. Furthermore, by rotating the screw 35 and the slide cylinder 34 to make threaded movements, the device can easily clamp and fix louvers with different aspect ratios.

[0023] Please see Figure 2 The cutting mechanism 6 includes a hanging plate 61. The lower end of the cylinder rod of the cylinder 5 is fixedly connected to the hanging plate 61. A cutter 62 is fixedly connected to the middle of the lower end of the hanging plate 61. A pressure plate 63 is slidably connected to the outside of the cutter 62. A hanging rod 64 is slidably connected to the inside of the hanging plate 61. The hanging rod 64 and the pressure plate 63 are slidably connected. A compression spring 65 is provided on the outside of the hanging rod 64. One end of the compression spring 65 is fixedly connected to the hanging plate 61, and the other end of the compression spring 65 is fixedly connected to the pressure plate 63. By providing the compression spring 65, the pressure plate 63 can be reset. By the compression spring 65 acting on the pressure plate 63, the pressure plate 63 can slide on the outside of the cutter 62. This prevents material jumping after the cutter 62 is separated from the louver after processing.

[0024] The specific implementation process of this utility model is as follows: In use, the louvers are placed on the base plate 1. Then, according to the length-to-width ratio adjustment device of the louvers, the screw 35 is manually rotated. The rotation of the screw 35 and the sliding cylinder 34 make a threaded movement, thereby changing the distance between the sliding cylinders 34 in the horizontal direction and the distance between the sliding cylinders 34 in the vertical direction of the base plate 1. Then, the motor 2 is started to drive the turntable 31 to rotate. The rotation of the turntable 31 causes the guide rail 32 to change position. The change in the position of the guide rail 32 causes the sliding rod 33 to change position. The sliding rod 33 drives the screw 35 to move. The screw 35 drives the sliding cylinder 34 to move. The sliding cylinder 34 causes the clamping rod 37 to change position. The change in the position of the clamping rod 37 makes contact with the louvers and clamps the louvers. Positioning is performed, and then cylinder 5 is activated. Cylinder 5 drives the cylinder rod to extend, which in turn moves the hanging plate 61. The hanging plate 61 moves the cutter 62 downward, causing it to contact the louver and cut it. Simultaneously, the downward movement of the hanging plate 61 moves the compression spring 65, which in turn moves the pressure plate 63 downward, causing it to contact the louver. During this process, the pressure plate 63 contacts the clamping rod 37, pressing the clamping rod 37 into the slide cylinder 34. The compression spring 65 acts on the pressure plate 63, allowing it to slide outside the cutter 62. This prevents material from jumping out after the cutter 62 is separated from the louver.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
