AI Technical Summary
Existing angle adjustment devices cannot effectively clamp and fix irregularly shaped stones when processing them, resulting in misalignment of the stones during processing.
The design employs a hydraulic rod and an air pump in conjunction with a sliding strip. The hydraulic rod pushes the moving plate to contact the irregularly shaped stone, while the air pump draws in air to make the sliding strip fit tightly against the stone surface, increasing the contact area and ensuring stable clamping.
This effectively avoids misalignment of irregularly shaped stones during processing and improves processing stability.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of angle adjustment devices, and in particular relates to an automatic angle adjustment device for chamfering. Background Technology
[0002] An angle adjustment device refers to a device that allows for angle adjustment of the stone during processing, enabling the stone to rotate automatically and allowing for chamfering of multiple corners of the stone.
[0003] Currently, existing angle adjustment devices clamp and fix the stone during use to prevent misalignment when all four corners of the stone are beveled. However, when dealing with irregularly shaped stones, such as wavy and curved stones, the clamping structure cannot fit them tightly enough, resulting in unstable clamping and causing misalignment during processing.
[0004] To address this issue, we propose an automatic angle adjustment device for chamfering. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the prior art that it is impossible to effectively clamp and fix irregularly shaped stones, and to propose an automatic angle adjustment device for chamfering processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic angle adjustment device for chamfering includes a rectangular box. Two fixed frames are fixedly connected to the outer surface of the rectangular box. A hydraulic rod is fixedly connected to the inner wall of each fixed frame. A movable plate is fixedly connected to the telescopic end of each hydraulic rod. A rectangular frame is fixedly connected to the upper surface of each movable plate. A rectangular block is fixedly connected to the inner wall of each rectangular frame. Several identical sliding strips are slidably connected inside each rectangular block. An air pump is fixedly connected to the upper surface of each movable plate. An input pipe is fixedly connected to the input end of each air pump. An output pipe is fixedly connected to the output end of each air pump. The ends of two output pipes that are close to each other are respectively fixedly connected to the opposite sides of the two rectangular frames.
[0008] Preferably, the back of the rectangular box is fixedly connected to the chamfering processing device body, and the inner wall of the rectangular box is rotatably connected to two limiting shafts, with a limiting plate fixedly connected to the end of each limiting shaft away from the chamfering processing device body.
[0009] Preferably, the rectangular box has a baffle inside, and the front of the baffle contacts the back of the two limiting plates.
[0010] Preferably, the rectangular box has a placement frame inside, and the placement frame has grooves on both sides.
[0011] Preferably, the inner wall of the rectangular box is fixedly connected to two sliders, each slider is disposed in the inner cavity of the slide groove, and the two sliders are fixedly connected to the inner wall of the rectangular box on opposite sides.
[0012] Preferably, a fixing plate is fixedly connected to the inner top wall of the rectangular box, a stepper motor is fixedly connected to the upper surface of the fixing plate, and a turntable is fixedly connected to the output end of the stepper motor.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] By installing a fixed frame, a stable supporting force can be provided for the hydraulic rod. The operation of the hydraulic rod can push the moving plate to the position of the irregular stone. When the moving plate moves towards the irregular stone, the sliding strip on the top of the moving plate will contact the side of the irregular stone. Since the surface of the stone is an irregular curved surface, the sliding strip that first contacts the surface of the irregular stone will retract into the interior of the rectangular block until all the sliding strips are in contact with the surface of the irregular stone. Then, the air pump is controlled to operate. When the air pump is running, it can draw outside air into the interior of the input pipe and enter the rectangular frame through the output pipe. The air entering the rectangular frame will quickly fill the interior of the rectangular block, thereby squeezing the sliding strips inside the rectangular block, making the sliding strips tightly contact the surface of the irregular stone, thus increasing the contact area between the sliding strips and the surface of the irregular stone, and avoiding instability problems caused by small contact area during the processing of irregular stone.

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-4 This embodiment provides an automatic angle adjustment device for chamfering. The automatic angle adjustment device for chamfering includes a rectangular box 1. Two fixing frames 2 are fixedly connected to the outer surface of the rectangular box 1. A chamfering device body 3 is fixedly connected to the back of the rectangular box 1. Two limiting shafts 10 are rotatably connected to the inner wall of the rectangular box 1. A limiting plate 7 is fixedly connected to the end of each limiting shaft 10 away from the chamfering device body 3. By setting up the chamfering device body 3, the limiting shafts 10 and the limiting plate 7, the chamfering device body 3 can be used to chamfer the stone, while the limiting shafts 10 can drive the limiting plate 7 to rotate.
[0022] Each fixed frame 2 has a hydraulic rod 8 fixedly connected to its inner wall, and each hydraulic rod 8 has a movable plate 5 fixedly connected to its telescopic end. A baffle 6 is snapped into the inside of the rectangular box 1. The front of the baffle 6 contacts the back of the two limiting plates 7. By setting the baffle 6, external dust can be blocked from entering the internal space of the rectangular box 1, and the presence of the limiting plates 7 can limit the position of the baffle 6.
[0023] Each movable plate 5 has a rectangular frame 4 fixedly connected to its upper surface, and a rectangular block 11 fixedly connected to the inner wall of each rectangular frame 4. Several identical sliding strips 12 are slidably connected inside each rectangular block 11. A placement frame 19 is provided inside the rectangular box 1. Slide grooves 18 are provided on both sides of the placement frame 19. By providing the placement frame 19, some tools can be stored, which can play a better auxiliary role.
[0024] Each movable plate 5 has an air pump 14 fixedly connected to its upper surface. Each air pump 14 has an input pipe 15 fixedly connected to its input end and an output pipe 13 fixedly connected to its output end. Two sliders 20 are fixedly connected to the inner wall of the rectangular box 1. Each slider 20 is located in the inner cavity of the slide groove 18. The two sliders 20 are fixedly connected to the inner wall of the rectangular box 1 on opposite sides. With the sliders 20 and the slide groove 18, the placement frame 19 can slide along the sliders 20 through the slide groove 18. The sliding relationship between the sliders 20 and the slide groove 18 can be used to limit the placement frame 19.
[0025] Two output tubes 13 are fixedly connected at their close ends to the two rectangular frames 4 at their far ends. A fixing plate 16 is fixedly connected to the inner top wall of the rectangular box 1. A stepper motor 17 is fixedly connected to the upper surface of the fixing plate 16. A turntable 9 is fixedly connected to the output end of the stepper motor 17. By setting the fixing plate 16, the stepper motor 17 can be fixed. The operation of the stepper motor 17 can drive the turntable 9 to rotate, thereby driving the irregularly shaped stone placed on the surface of the turntable 9 to rotate.
[0026] The working principle of this utility model is as follows: In use, the irregularly shaped stone is first placed on the upper surface of the turntable 9. Then, the hydraulic rod 8 is controlled to move, pushing the moving plate 5 towards the irregularly shaped stone. As the moving plate 5 moves towards the irregularly shaped stone, the sliding strip 12 above it contacts the side of the stone. Because the stone surface is an irregular curved surface, the sliding strip 12 that first contacts the surface of the irregularly shaped stone will retract into the rectangular block 11 until all the sliding strips 12 are in contact with the surface of the irregularly shaped stone. Then, the air pump 14 is controlled to operate. During operation, the air pump 14 draws outside air into the input pipe 15 and into the rectangular frame 4 through the output pipe 13. In the process, the gas entering the rectangular frame 4 quickly fills the interior of the rectangular block 11, which in turn squeezes the sliding strip 12 inside the rectangular block 11, making the sliding strip 12 tightly contact the surface of the irregular stone, thereby increasing the contact area between the sliding strip 12 and the surface of the irregular stone. Then, the chamfering processing device body 3 is controlled to chamfer the stone. When it is necessary to process several other corners, the hydraulic rod 8 is controlled to retract, so that the sliding strip 12 stops contacting the surface of the irregular stone. Then, the stepper motor 17 is controlled to run, so that the turntable 9 rotates. Then, the hydraulic rod 8 is controlled to extend to clamp and fix the stone, thus avoiding the problem of instability during the processing of irregular stone due to small contact area.
