Technical Field

[0001] This utility model relates to the field of sandblasting carrier technology, specifically a rotating turntable device for workpiece rotation. Background Technology

[0002] In the field of industrial manufacturing and surface treatment, the pretreatment of workpieces is one of the key steps to ensure the quality of subsequent processing. Among them, sandblasting is a highly efficient and universal surface cleaning and strengthening method, which is widely used to remove impurities such as oxide layers, rust, old coatings and burrs from the surface of workpieces, while improving the surface roughness of the workpieces and enhancing the adhesion of coatings or subsequent processing.

[0003] Traditional sandblasting equipment often features fixed carriers, resulting in a limited range of workpiece positioning and fixation methods during the sandblasting process. This makes it difficult to adapt to the flexible handling requirements of workpieces with different shapes and sizes. In particular, when dealing with complex shapes or workpieces requiring multi-angle sandblasting, multiple clamping and adjustment of the workpiece position are often necessary. This not only increases the difficulty of operation and production cycle but may also lead to the accumulation of workpiece positioning errors due to multiple clamping, affecting the uniformity and consistency of the sandblasting effect. Therefore, it is necessary to design a turntable device for workpiece rotation to improve the above-mentioned problems. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a workpiece rotation turntable device, which aims to solve the problem that in the prior art, when sandblasting carriers sandblast workpieces at multiple angles, it is often necessary to clamp and adjust the workpiece position multiple times, which affects the uniformity of the sandblasting effect.

[0033] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example: Please refer to Figures 1-5This embodiment provides a rotary table device for workpiece rotation, including a turntable 1, a base plate 2, a drive motor 3, a driving shaft 4, a driven shaft 5, a rotation linkage assembly, a mounting base 8, and a carrier 9. The bottom of the turntable 1 has a mounting chamber. The base plate 2 is rotatably connected to the bottom of the turntable 1. The drive motor 3 is fixedly mounted at the center of the bottom of the base plate 2. The output end of the drive motor 3 passes through the base plate 2 and is placed within the mounting chamber of the turntable 1. The driving shaft 4 is vertically arranged, and its top end is fixedly connected to the center of the top of the mounting chamber of the turntable 1. The bottom end of the driving shaft 4 is connected to the output end of the drive motor 3 via a linkage. The shaft is fixedly connected, and the driven shaft 5 is vertically set. The driven shaft 5 is set inside the mounting cavity of the turntable 1, and multiple driven shafts 5 are evenly spaced along the circumference of the driving shaft 4. The top of the driven shaft 5 extends to the outside of the turntable 1 and is rotatably connected to the turntable 1. The self-rotation linkage component is set between the driven shaft 5 and the base plate 2. When the drive motor 3 drives the turntable 1 to rotate, the self-rotation linkage component drives the driven shaft 5 to rotate. The top of each driven shaft 5 is fixedly connected to a mounting base 8. The carrier 9 is sleeved on the outside of the mounting base 8. The carrier 9 serves as a carrier for fixing the workpiece and can be set according to the requirements of the workpiece to be sandblasted.

[0035] Specifically, the drive motor 3 drives the active shaft 4 to rotate, which in turn drives the turntable 1 to rotate, thereby causing the driven shaft 5, the mounting base 8, the carrier 9, and the workpiece fixed on the carrier 9 to rotate synchronously. When the driven shaft 5 rotates, the self-rotation linkage component allows the driven shaft 5 to rotate, which in turn drives the mounting base 8, the carrier 9, and the workpiece fixed on the carrier 9 to rotate, thus achieving multi-angle sandblasting of the workpiece, improving the uniformity of the workpiece during sandblasting, and greatly improving the pretreatment effect of the workpiece.

[0036] In this preferred embodiment, the number of driven shafts 5, mounting bases 8, and carriers 9 is set to eight, enabling simultaneous sandblasting of eight workpieces and improving work efficiency. Of course, in other embodiments, the number of driven shafts 5, mounting bases 8, and carriers 9 can be set to six, nine, ten, etc., depending on requirements.

[0037] In this embodiment, the self-rotation linkage component includes an internal gear ring 7 and a gear 6. The internal gear ring 7 is fixedly connected to the top of the base plate 2 and placed in the mounting cavity of the turntable 1. Each driven shaft 5 is fixedly connected to a gear 6 at its bottom end. The gear 6 meshes with the internal gear ring 7. When the driven shaft 5 rotates with the turntable 1, the gear 6 also rotates synchronously with the driven shaft 5. Through the meshing of the gear 6 with the internal gear ring 7, the gear 6 rotates, thereby driving the driven shaft 5 to rotate, which in turn drives the mounting base 8, the carrier 9, and the workpiece fixed on the carrier 9 to rotate.

[0038] In this embodiment, asFigure 4 and Figure 5 As shown, the rotary table device for workpiece rotation also includes a disassembly and assembly structure, which is located in the mounting base 8 and is used to quickly disassemble and assemble the carrier 9 with the mounting base 8.

[0039] The mounting base 8 includes a base 81 and a mounting block 82 fixedly connected to the top of the base 81. The mounting block 82 is integrally formed with the base 81. The mounting block 82 has a receiving cavity 821 inside, which extends into the base 81. The outer walls on both sides of the base 81 have symmetrical first through holes 811 communicating with the receiving cavity 821. The outer walls on both sides of the mounting block 82 have symmetrical second through holes 822 communicating with the receiving cavity 821.

[0040] The disassembly and assembly structure includes two movable plates 83 disposed inside the receiving cavity 821. Each of the two movable plates 83 is fixedly connected to a pressing rod 84 passing through the first through hole 811 and a retaining post 85 passing through the second through hole 822 on the opposite side. A plurality of reset pieces 86 are fixedly connected to the side of the two movable plates 83 that are close to each other. The reset pieces 86 are preferably helical springs.

[0041] The bottom of the carrier 9 is provided with a mounting groove 91 for accommodating the mounting block 82. Both the mounting groove 91 and the mounting base 8 have a square cross-section. The inner walls on both sides of the mounting groove 91 are provided with positioning holes 92 for positioning pins 85 to be inserted.

[0042] Specifically, when assembling the carrier 9 and the mounting base 8, the carrier 9 is vertically inserted into the mounting base 8 from top to bottom, so that the mounting block 82 of the mounting base 8 is aligned and inserted into the mounting groove 91 of the carrier 9. When the carrier 9 and the mounting base 8 are in place, the retaining pin 85 is placed at the retaining hole 92. The resetting member 86 pushes the two moving plates 83 to press tightly against the inner wall of the receiving cavity 821, so that the retaining pin 85 passes through the second through hole 822 and is inserted into the retaining hole 92, locking the carrier 9 and the mounting base 8 together. The installation is secure; when disassembling the carrier 9 from the mounting base 8, by pressing the two pressing rods 84 into the first through hole 811, the pressing rods 84 push the two moving plates 83 to move closer, and at the same time the moving plates 83 drive the retaining pin 85 to disengage from the retaining hole 92 and move into the first through hole 811, thereby releasing the locking effect on the carrier 9, thus facilitating the quick disassembly of the carrier 9. The disassembly and assembly structure facilitates the quick disassembly and replacement of the carrier 9 and the mounting base 8, so as to replace the carrier 9 with a suitable one according to different workpieces to be sandblasted, thereby improving applicability.

[0043] In this embodiment, as Figure 4 and Figure 5As shown, a limiting strip 87 is also provided on the outer wall of the mounting block 82, and a limiting groove 93 is provided on the inner wall of the mounting groove 91 for the limiting strip 87 to be inserted. The limiting strip 87 and the limiting groove 93 are vertically positioned and the limiting strip 87 is integrally formed with the mounting block 82. When the carrier 9 and the mounting base 8 are assembled, the mounting block 82 of the mounting base 8 is inserted into the mounting groove 91 of the carrier 9. At this time, the limiting strip 87 on the mounting block 82 is inserted into the limiting groove 93 in the mounting groove 91, which plays a limiting and guiding role in the assembly of the carrier 9 and the mounting base 8, so that the fixing post 85 and the fixing hole 92 can be accurately aligned.

[0044] In this embodiment, the end of the retaining pin 85 away from the moving plate 83 is provided with an inclined surface, and the bottom end of the mounting groove 91 is provided with a sliding inclined flared opening that cooperates with the inclined surface. When the carrier 9 and the mounting base 8 are assembled, the carrier 9 is vertically inserted into the mounting base 8 from top to bottom, and the inclined flared opening of the mounting groove 91 contacts the inclined surface of the retaining pin 85, thereby automatically pushing the retaining pin 85 into the second through hole 822. When the retaining pin 85 is placed at the retaining hole 92, the retaining pin 85 is pushed to move and insert into the retaining hole 92 under the action of the reset member 86, thereby improving the convenience of assembling the carrier 9 and the mounting base 8.

[0045] In this embodiment, as Figure 1 and Figure 2 As shown, multiple mounting plates 10 are fixedly connected at equal intervals along the circumferential direction at the bottom of the base plate 2. The mounting plates 10 are C-shaped. One end of the mounting plate 10 is fixedly connected to the base plate 2 by bolts, and the other end of the mounting plate 10 is provided with mounting holes. The mounting plates 10 are installed and fixed in the processing chamber of the sandblasting equipment by bolts passing through the mounting holes.

[0046] Working Principle: During use, the workpiece to be sandblasted is placed and fixed outside the carrier 9. The drive motor 3 drives the active shaft 4 to rotate, which in turn drives the turntable 1 to rotate, thereby causing the driven shaft 5, the mounting base 8, the carrier 9, and the workpiece to rotate synchronously. When the driven shaft 5 rotates, the gear 6 also rotates synchronously with it. Through the meshing of the gear 6 with the internal gear ring 7, the gear 6 rotates, which in turn drives the driven shaft 5 to rotate, thereby causing the mounting base 8, the carrier 9, and the workpiece to rotate. This achieves multi-angle sandblasting of the workpiece, improving the uniformity of the sandblasting operation and greatly improving the pretreatment effect of the workpiece. When sandblasting different workpieces, by pressing the two pressing rods 84 into the first through hole 811, the pressing rods 84 push the two moving plates 83 to move closer together. At the same time, the moving plates 83 drive the fixed insert... The post 85 moves out of the retaining hole 92 and into the first through hole 811, releasing the locking effect on the carrier 9, thus facilitating the quick disassembly of the carrier 9. Then, the matching carrier 9 is assembled with the mounting base 8, and the carrier 9 is vertically inserted into the mounting base 8 from top to bottom, so that the mounting block 82 of the mounting base 8 is aligned and inserted into the mounting groove 91 of the carrier 9. When the carrier 9 and the mounting base 8 are assembled in place, the retaining post 85 is placed at the retaining hole 92. Through the action of the reset member 86, the two moving plates 83 are pushed to press tightly against the inner wall of the receiving cavity 821, so that the retaining post 85 passes through the second through hole 822 and is inserted into the retaining hole 92, locking the carrier 9 and the mounting base 8, thus securing the carrier 9 and the mounting base 8. The disassembly and assembly structure facilitates the quick disassembly and replacement of the carrier 9 and the mounting base 8, so that the matching carrier 9 can be replaced according to different workpieces to be sandblasted, thereby improving applicability.

[0047] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
