[0001] The present invention relates to the technical field of sandblasting equipment, and specifically to a fully automatic high-precision sandblasting equipment. Background Art

[0002] A sandblasting equipment is an industrial mechanical equipment that processes the surface of an object by high-speed spraying abrasives (such as sand grains, metal shots, mineral particles, etc.). Its core principle is to use compressed air, liquid (such as water) or other power sources to accelerate the abrasives to form a high-speed jet beam, impact the surface of the workpiece, and change the surface morphology and properties through the dual actions of physical impact and micro-cutting.

[0003] The patent application with the Chinese patent application number CN202020125996.X discloses a fully automatic high-precision rotary sandblasting equipment. Although this application can repeatedly sandblast the panel through the sandblasting gun, with a remarkable sandblasting effect and improved sandblasting efficiency and working efficiency, when this application is put into use, the clamping effect is poor when sandblasting precision parts such as gears, resulting in shaking and displacement of the gears during rotation. Therefore, improvements need to be made to this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully automatic high-precision sandblasting equipment to solve the problems raised in the above background art.

[0011] According to the above technical solution, the positioning plate is fixedly connected to the bottom of the rotating base and is located outside the guiding chute, the second supporting spring is fixedly connected to the other side of the positioning plate, the sliding arm is fixedly connected to the other end of the second supporting spring, and the inner ring contact arc plate is fixedly connected to the side of the sliding arm far from the second supporting spring. The second supporting spring can support the sliding arm and the inner ring contact arc plate.

[0012] According to the above technical solution, it further includes a gear body. The gear body is arranged on the top of the rotating base and is located outside the inner ring contact arc plate. The inner ring contact arc plate can contact the inner wall of the inner ring of the gear body.

After the speed is reduced, the electromagnetic plate maintains the adsorption force. At the same time, the support spring I resets to drive the sliding arc plate to abut against the outer side of the gear, forming a two-way clamping inside and outside to ensure the stability of the gear during precision sandblasting; 3. The centrifugal force causes the sliding arc plate to move outward, completely exposing the top surface of the gear. The sandblasting machine can quickly cover the entire area, improving efficiency. The rotating base rotates at high speed to drive the gear to rotate synchronously, realizing uniform sandblasting and reducing repetitive operations; 4. The shielding plate is adjusted to a vertical state through the electric telescopic rod, accurately defining the sandblasting area to avoid over-sandblasting. The sliding arc plate resets to cover the non-target area, and local fine processing is realized in combination with low-speed rotation; 5. The electric telescopic rod drives the shielding plate to flexibly adjust the angle in the positioning rotating frame, and can quickly switch between the open and shielding states to protect the non-sandblasted area of the gear.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0022] Embodiment 1. Please refer to Figures 1 - 3 , the present invention provides a technical solution: a fully automatic high-precision sandblasting device, including a support base 1, and further including a rotating assembly 5.

[0023] Among them, the rotating assembly 5 includes a gear set 501, a driving motor 502, a sieve plate 503, a rotating seat 504, a connecting shaft 505, a first rotating gear 506, a second rotating gear 507 and a rotating base 508: The gear set 501 is fixedly connected to the front side of the top of the sandblasting machine 2, the driving motor 502 is fixedly connected to the top of the gear set 501, the gear set 501 has an output shaft, the connecting shaft 505 is fixedly connected to the output shaft of the gear set 501, the rotating gear one 506 is fixedly connected to the bottom end of the connecting shaft 505, the rotating gear two 507 is meshed with the outside of the rotating gear one 506, the rotating base 508 is fixedly connected to the top of the rotating gear two 507, the rotating seat 504 is rotatably connected to the middle of the bottom of the rotating base 508, the sieve plate 503 is fixedly connected to the inner bottom of the sandblasting machine 2.

[0024] Embodiment 2. Please refer to Figures 1 - 10 , on the basis of Embodiment 1, the present invention provides a technical solution: further comprising a shielding assembly 6, and the shielding assembly 6 is composed of a guiding chute 601, a supporting spring one 602, a guiding slider 603, a sliding arc plate 604, a positioning rotating frame 605, a lifting frame 606, an electric telescopic rod 607, a sliding block 608, a rotating arm 609, a connecting frame 610, a shielding plate 611 and an elastic connecting plate 612.

[0025] The guiding chute 601 is opened inside the rotating base 508, the supporting spring one 602 is fixedly connected to the inside of the guiding chute 601, the guiding slider 603 is fixedly connected to the other end of the supporting spring one 602, the sliding arc plate 604 is fixedly connected to the top of the guiding slider 603, the positioning rotating frame 605 is fixedly connected to the top of the side of the sliding arc plate 604 away from the supporting spring one 602, the lifting frame 606 is fixedly connected to the middle of the top of the sliding arc plate 604, the electric telescopic rod 607 is fixedly connected to the middle of the top of the lifting frame 606, the electric telescopic rod 607 has a telescopic end, the sliding block 608 is fixedly connected to the telescopic end of the electric telescopic rod 607, the rotating arm 609 is rotatably connected to the middle part inside the sliding block 608, the connecting frame 610 is rotatably connected to the side of the rotating arm 609 away from the sliding block 608, the shielding plate 611 is fixedly connected to the bottom of the connecting frame 610, and the elastic connecting plate 612 is fixedly connected to the outside of the shielding plate 611.

[0026] Further comprising a supporting assembly 9, and the supporting assembly 9 is composed of a positioning plate 901, a supporting spring two 902, a sliding arm 903 and an inner ring contact arc plate 904.

[0027] The positioning plate 901 is fixedly connected to the bottom of the rotating base 508 and is located outside the guiding chute 601, the supporting spring two 902 is fixedly connected to the other side of the positioning plate 901, the sliding arm 903 is fixedly connected to the other end of the supporting spring two 902, the inner ring contact arc plate 904 is fixedly connected to the side of the sliding arm 903 away from the supporting spring two 902, and the supporting spring two 902 can support the sliding arm 903 and the inner ring contact arc plate 904.

[0028] It also includes a gear body 7, which is arranged on the top of the rotating base 508 and located outside the inner ring contact arc plate 904. The inner ring contact arc plate 904 can contact the inner wall of the inner ring of the gear body 7.

[0029] The guiding slider 603 can slide in the guiding chute 601. The telescopic end of the electric telescopic rod 607 penetrates through the top of the lifting frame 606 and extends into the lifting frame 606 to be fixedly connected with the top of the sliding block 608. When the electric telescopic rod 607 works, it can drive the sliding block 608 to move.

[0030] An electromagnetic plate is arranged outside the inner ring contact arc plate 904. The sliding arm 903 can slide in the guiding chute 601. When the sliding arm 903 slides, it can drive the inner ring contact arc plate 904 to move synchronously.

[0031] One side of the shielding plate 611 close to the sliding arc plate 604 is rotatably connected to the positioning rotating frame 605, and the shielding plate 611 can rotate on the positioning rotating frame 605.

[0032] There are four shielding plates 611, which are annularly distributed on the top of the rotating base 508. The four shielding plates 611 are all connected by elastic connecting plates 612, which can enable the elastic connecting plates 612 to deform synchronously for adaptive connection when the shielding plates 611 are displaced.

[0033] When sandblasting the gear is required, place the middle of the gear on the control drive motor 502 to work, which can enable the drive motor 502 to drive the gear set 501 to work. At this time, the gear set 501 drives the connecting shaft 505 and the rotating gear one 506 to rotate, so that the rotating gear one 506 meshes with the rotating gear two 507, which can enable the rotating base 508 to rotate. At this time, the rotating base 508 rotates in the rotating seat 504 on the sieve plate 503. When the rotating speed of the rotating base 508 is relatively fast, the centrifugal force on the rotating base 508 is relatively large. At this time, the supporting spring two 902 is compressed under the action of the centrifugal force, which can enable the supporting spring two 902 to push the inner ring contact arc plate 904 through the sliding arm 903, so that the inner ring contact arc plate 904 fits against the inner wall of the gear. Through the electromagnetic plate arranged outside the inner ring contact arc plate 904, the inner ring contact arc plate 904 can adsorb the inner wall of the inner ring of the gear, and the inner ring contact arc plate 904 can push the inner wall of the inner ring of the gear outward, thereby fixing the inner wall of the inner ring of the gear.

[0034] When the rotating base 508 rotates rapidly, the centrifugal force on the rotating base 508 can compress the first support spring 602. At the same time, when the first support spring 602 is compressed, the guiding slider 603 and the sliding arc plate 604 slide outward in the guiding chute 601. At this time, the top surface of the gear is completely exposed. And because the rotating speed of the rotating base 508 is relatively fast, the sandblasting machine 2 can directly perform rapid sandblasting on the gear surface during operation, accelerating the sandblasting efficiency and improving the sandblasting uniformity at the same time.

[0035] When precise sandblasting work needs to be carried out on the top surface of the gear, the rotation speed of the rotating base 508 is controlled to decrease. At this time, the centrifugal force on the rotating base 508 decreases. At the same time, under the adsorption ability of the electromagnetic plate on the outer side of the inner ring contact arc plate 904, the position of the gear can be fixed to prevent the gear from not being clamped due to the decrease in centrifugal force. Since the centrifugal force of the rotating base 508 decreases, the first support spring 602 in the guiding chute 601 can restore its elasticity, causing the sliding arc plate 604 to move to the outside of the gear and abut against the sliding arc plate 604 through the outer contour of the gear. Then, the electric telescopic rod 607 is started, which can drive the sliding block 608 to slide downward in the lifting frame 606, so that the sliding block 608 pushes the rotating arm 609, causing the connecting frame 610 on the other side of the rotating arm 609 to be stressed, enabling the shielding plate 611 to rotate in the positioning rotating frame 605 on the sliding arc plate 604, making the shielding plate 611 perpendicular to the top of the sliding arc plate 604. At the same time, the shielding plate 611 can cover the outside of the top of the gear, facilitating the limitation of the sandblasting area when performing precise sandblasting on the top of the subsequent gear.
