DETAILED DESCRIPTION

[0016] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings, and the purpose is to help the technical personnel in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present application, and to help its implementation.

[0017] Specifically, as shown in Figures 1 to 9 A heavy plate shearing machine special portable rear material blocking adjusting device, comprising a baffle 1 installed below the heavy plate shearing machine, an adjusting mechanism 2 installed on both sides of the baffle 1, a driving mechanism 3 installed below the adjusting mechanism 2, and a rectangular steel frame 4 installed between the bottoms of the two groups of adjusting mechanisms 2.

[0018] It should be noted that the device has a compact structure, and the tool holder only needs to be installed with the same structure, and can be easily installed in a very small space. The whole structure has an additional heavy-duty bull eye bearing part, and other parts are necessary components for rear material blocking. Any rear material blocking is required, which reduces the installation difficulty and has stronger applicability.

[0019] In detail, this layout structure is compact, and each part works cooperatively to realize accurate adjustment of the rear material blocking. The rectangular steel frame 4 provides a stable support structure for the whole device, ensuring the overall stability of the device during adjustment. The baffle 1 as a component directly contacting the plate material, the accurate adjustment of its position determines the accuracy of plate cutting. The adjusting mechanism 2 and the driving mechanism 3 cooperate with each other to realize accurate adjustment of the baffle 1 in the front and rear, up and down, and other directions.

[0020] The connecting unit 21 includes a mounting plate 211 welded to the baffle 1 , a slide 212 fixedly connected to the mounting plate 211 via hexagonal screws, and an adjustment seat 213 respectively connected to the mounting plate 211 and the slide 212 .

[0021] It should be noted that when front and rear adjustment is required, the mounting screws are loosened, and the waist-shaped holes on the mounting surface of the baffle 1 are matched, and the positions of the two ends of the baffle 1 are adjusted through the fine top screws on the adjustment seat 213 to achieve front and rear adjustment.

[0022] The sliding seat 212 is provided with a rolling guide groove, and a bull's eye bearing is installed in the mounting plate 211 . The rolling guide groove is adapted to the ball of the bull's eye bearing.

[0023] It should be noted that when the elevation angle needs to be adjusted, the elevation angle adjustment operation can be completed by using the bull's eye bearing spherical surface as the central fulcrum, adjusting the front and rear hexagonal screws up and down, and fixing the elevation angle with the top screw below.

[0024] In detail, the welding of the mounting plate 211 and the baffle 1 ensures the firmness of the connection, and the slide 212 is connected to the mounting plate 211 by a hexagonal screw, which is convenient for disassembly and adjustment; the rolling guide groove opened on the slide 212 is adapted to the bull's eye bearing ball installed in the mounting plate 211. This design not only provides smooth guidance for the movement of the baffle, but also greatly enhances the load-bearing capacity and impact resistance of the device.

[0025] In addition, when it is necessary to adjust the baffle 1 forward and backward, loosen the mounting screws, use the waist-shaped holes on the mounting surface of the baffle 1, and adjust the positions of the two ends of the baffle 1 accurately through the fine-threaded top screws on the adjustment seat 213 to achieve fine-tuning in the forward and backward directions; and when adjusting the elevation angle, the spherical surface of the bull's eye bearing is used as the central fulcrum, and the elevation angle is easily completed by adjusting the front and rear hexagonal screws up and down, and fixing the elevation angle with the top screw below; the use of the bull's eye bearing not only improves the load-bearing capacity of the device, but also ensures that the gap will not increase in any direction by fixing it with the center ball bearing, so that the adjustment accuracy remains stable at all times.

[0026] The transmission unit 22 includes a rear stop guide bracket 221 that is slidably connected to the outer side of the adjustment seat 213, a light rod 222 installed inside the rear stop guide bracket 221, a ball screw 223 that passes through the rear stop guide bracket 221 and is rotatably connected to it through a bearing, and a first gear transmission wheel 224 installed at the bottom of the ball screw 223.

[0027] It should be noted that the second gear transmission wheel 34 drives the two sets of first gear transmission wheels 224 to rotate through the belt, and then drives the ball screw 223 to rotate. Under the guidance of the light rod 222, the movement of the slide 212 is realized, thereby driving the baffle 1 to perform corresponding position adjustment; this transmission method not only has high transmission efficiency, but also can achieve high-precision position control.

[0028] In detail, the polished rod 222 provides a stable guide for the movement of the slide 212, ensuring that the baffle 1 maintains linear motion during the adjustment process; the ball screw 223 converts the rotational motion into linear motion, achieving precise displacement of the slide 212.

[0029] The driving mechanism 3 includes an adapter plate 31 connected to the bottom of the rear stop guide bracket 221, a bearing seat 32 connected to the adapter plate 31, a small reducer 33 installed on the bearing seat 32, a small motor 33 linked to the small reducer 33, and a second gear transmission wheel 34 connected to the reducer screw of the small reducer 33. The two groups of the first gear transmission wheels 224 and the second gear transmission wheels 34 are directly connected through belt drive.

[0030] It should be noted that when the driving mechanism 3 is working, the small motor 34 drives the small reducer 33 to operate, and the small reducer 33 drives the second gear transmission wheel 34 to rotate through the reducer screw. This driving method has a simple structure and high transmission efficiency, and can provide stable power for the adjustment of the baffle.

[0031] The adapter plate 31 is provided with an adjustment slot 35 , an adjustment screw 36 is provided through the adjustment slot 35 , a tensioning wheel 37 is installed at the bottom of the adjustment screw 36 , and the surface of the tensioning wheel 37 is provided to contact with the belt.

[0032] It should be noted that by adjusting the position of the adjusting screw in the adjusting slot, the tension of the tensioning pulley on the belt can be changed, thereby ensuring the stability and reliability of the belt transmission and avoiding the influence of transmission accuracy due to loose belt.

[0033] The specific working method is described below with specific embodiments: Example 1

[0034] When adjusting the back gauge forward and backward, the operator first loosens the hexagonal screw connecting the mounting plate 211 and the slide 212; since there is a waist-shaped hole on the mounting surface of the baffle 1, the fine threaded top screw on the rotating adjustment seat 213 can be used to push or pull the two ends of the baffle 1, thereby adjusting the position of the baffle 1 in the forward and backward direction; this adjustment method is simple and convenient, and can quickly and accurately meet the requirements for adjusting the forward and backward position of the back gauge in actual processing; Example 2

[0035] When the rear baffle angle needs to be adjusted, the operator uses the center of the ball surface of the eye bearing in the installation plate 211 as a fulcrum to rotate the front and rear inner hexagonal screws to make the slide 212 move up and down around the ball surface of the eye bearing; after adjusting to the appropriate angle, the angle is fixed by the upper screw; during the entire adjustment process, the eye bearing not only provides a flexible rotating fulcrum, but also the design of the center ball bearing dead top ensures that there is no problem of increased gap after the angle adjustment, ensuring the stability of the adjustment accuracy and meeting the accurate adjustment requirements of the parallelism of the rear baffle and the upper and lower directions of the lower knife.

[0036] The application is described above in conjunction with the drawings, and it is obvious that the specific implementation of the application is not limited by the above method. Any non-essential improvement or direct application of the above concept and technical solution of the application to other occasions is within the protection scope of the application.
