Detailed Implementation

[0020] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] Example 1: As Figure 1-3 As shown, a rotating tooling fixture includes: a connecting rod 1, a sleeve 2, a rotating column 3, side plates 4, a gear 5, and a toothed plate 6. The bottom end of the connecting rod 1 is used to connect with a chain link 9; the bottom end of the sleeve 2 is sleeved over the connecting rod 1, and the sleeve 2 is rotatably connected to the connecting rod 1; one end of the rotating column 3 is sleeved over the top end of the sleeve 2 and connected to the sleeve 2; the top end of the rotating column 3 is used to support the object to be rotated; two side plates 4 are respectively disposed on both sides of the rotating column 3; the space between the two side plates 4 is used to accommodate a track 11; the gear 5 is sleeved over the sleeve 2 and connected to the sleeve 2; one end of the toothed plate 6 is connected to the top end of the side plate 4, and the other end of the toothed plate 6 is provided with a rack portion 611 that drives the gear 5.

[0022] In practice, the object to be rotated can be a glass bottle. The chain and sprocket allow the chain to move. After connecting the rotating column 3 to the chain, the movement of the chain drives the rotating column 3 to move. The sleeve 2 and the rotating column 3 can be detachably connected via a spring pin. During the movement of chain link 9, chain link 9 drives the connecting rod 1 to move, and the connecting rod 1 drives the sleeve 2 to move. The sleeve 2 rotates through the engagement of gear 5 and toothed plate 6, thereby driving the rotating column 3 to rotate. A tray can be connected to the top of the rotating column 3 to hold the object to be sprayed.

[0023] The side plate 4 can shield the left and right sides of the track 11, while the toothed plate 6 can shield the upper part of the track 11 to a certain extent, thereby avoiding or reducing the entry of paint into the space of the track 11.

[0024] This embodiment utilizes the driving force of the chain conveyor to simply realize the rotation of the rotating column 3, and the movement stability can be improved to a certain extent through the cooperation of the gear 5 and the rack part 611.

[0025] Example 2: To further reduce the impact of coatings on transmission components, such as... Figure 2 As shown, in this embodiment, the toothed plate 6 includes a wide plate portion 61 and a narrow plate portion 62. One end of the wide plate portion 61 is connected to the top end of the side plate 4; the other end of the wide plate portion 61 is connected to the narrow plate portion 62; the rack portion 611 is located below the narrow plate portion 62; the orthographic projection of the narrow plate portion 62 toward the rack portion 611 completely covers the rack portion 611.

[0026] In the specific implementation process, if the transmission structure formed by the gear 5 and the rack 611 is directly exposed, it is easy for paint to adhere. At the same time, there is always a gap in the rack 611, and the paint may also enter the space below the rack 611. Therefore, in this embodiment, the tooth plate 6 is set as a wide plate 61 and a narrow plate 62. The narrow plate 62 covers the space above the gear 5 and the rack 611.

[0027] Example 3: To further reduce the impact of the coating on the transmission components, improvements were made based on Example 2, such as... Figure 1 As shown, in this embodiment, the tooling rotating fixture further includes a baffle 7, and the toothed plate 6 and the baffle 7 are each connected to a side plate 4, with the baffle 7 located above the gear 5.

[0028] In the specific implementation process, the toothed plate 6 and the baffle 7 are respectively located on both sides of the gear 5. The baffle 7 may also include a wide plate portion 61 and a narrow plate portion 62, but without a rack portion 611. Through the cooperation of the toothed plate 6 and the baffle 7, the above of the track 11 is covered as much as possible, reducing the impact of the paint on the transmission.

[0029] Example 4: To facilitate the disassembly of sleeve 2 and its upper components and improve rotational stability, improvements were made based on Examples 1-3, such as... Figure 1As shown, in this embodiment, the sleeve 2 includes: a first cylindrical portion 21, a second cylindrical portion 22, and a spacer 23. The first cylindrical portion 21 is connected to the rotating column 3; the second cylindrical portion 22 is connected to the bottom end of the first cylindrical portion 21, and the outer diameter of the second cylindrical portion 22 is larger than the outer diameter of the gear 5; the spacer 23 is fitted inside the second cylindrical portion 22 and connected to the second cylindrical portion 22; the spacer 23 is rotatably connected to the connecting rod 1 through a bearing 8; a gap is left between the spacer 23 and the connecting rod 1.

[0030] In specific implementation, the first cylindrical part 21 can be detachably connected to the rotating column 3 via a spring pin. The first cylindrical part 21 and the second cylindrical part 22 can be integrally formed. The spacer 23 can be connected to the second cylindrical part 22 via screws or bolts. When it is necessary to disassemble the sleeve 2, the screws or bolts can be unscrewed to separate the sleeve 2 from the spacer 23, thus eliminating the need to disassemble the components used for rotational connection, such as the bearing 8, making the disassembly operation more convenient. The bearing 8 can be as follows: Figure 1 As shown, two spacers are provided to improve rotational stability. The gap between the spacer 23 and the connecting rod 1 prevents friction between the spacer 23 and the connecting rod 1 during rotation. This also prevents the connecting rod 1 from hindering the rotation of the sleeve 2 and reduces wear on both the spacer 23 and the connecting rod 1.

[0031] Example 5: To further improve the movement stability of the device, improvements were made based on Example 4, such as... Figure 1 or Figure 3 As shown, in this embodiment, the tooling rotating fixture includes: a chain link 9 and a roller 10, the bottom end of the connecting rod 1 is connected to the chain link 9; the bottom end of the chain link 9 is connected to the roller 10.

[0032] In practice, if the part of the chain away from the sprocket is not supported, it may deviate in position under the action of gravity. Therefore, in this embodiment, rollers 10 are set below each chain link 9. By supporting the chain with rollers 10, the stability of the chain during movement can be improved, thereby improving the movement stability of the object to be sprayed, and ultimately improving the spraying effect.

[0033] Example 6: To improve the structural strength of the device and further reduce or prevent paint from entering the space of track 11, improvements were made based on Example 5, such as... Figure 1 As shown, in this embodiment, the tooling rotating fixture further includes: a track 11 and a reinforcing plate 12. The roller 10 is rotatably connected to the track 11, and the outer side wall of the track 11 is connected to the side plate 4. One end of the reinforcing plate 12 is connected to the inner wall of the side plate 4. The reinforcing plate 12 is connected to the top wall of the track 11, and at least a portion of the orthographic projection of the reinforcing plate 12 toward the sleeve 2 falls on the end of the sleeve 2.

[0034] In the specific implementation process, such as Figure 1 As shown, the side plate 4 can be connected to the side wall of the track 11 by bolts or screws, and the reinforcing plate 12 is connected to the top of the side wall of the track 11 by bolts or screws. To ensure the stability of the interaction between the rack portion 611 and the gear 5, it is necessary to ensure the positional stability of the gear plate 6, which in turn requires improving the positional stability of the side plate 4 to reduce the occurrence of the rotating column 3 failing to rotate due to the positional displacement of the side plate 4. The connection between the reinforcing plate 12 and the track 11 can further improve the structural strength of the side plate 4. In addition, the end of the reinforcing plate 12 away from the side plate 4 extends to the bottom of the second cylinder portion 22, so that the space above the track 11 is completely covered in the horizontal direction by the cooperation of the reinforcing plate 12 and the second cylinder portion 22, further reducing or preventing paint from entering the track 11.

[0035] Example 7: As Figure 3 As shown, in this embodiment, the link 9 includes an inner link segment 91 and an outer link segment 92; the inner link segment 91 and the outer link segment 92 are rotatably connected; the roller 10 is rotatably connected to the rotating shaft 921 of the outer link segment 92; the end of the rotating shaft 921 away from the roller 10 is connected to the bottom end of the connecting rod 1.

[0036] In specific implementation, the inner link segment 91 and the outer link segment 92 are the existing structures of the link 9. Both the inner link segment 91 and the outer link segment 92 have upper and lower plates. The two plates of the inner link segment 91 are connected by a connecting cylinder, and the two plates of the outer link segment 92 are connected by a rotating shaft 921. The rotating shaft 921 passes through the connecting cylinder, and the rotational connection between the inner link segment 91 and the outer link segment 92 is achieved through the cooperation of the rotating shaft 921 and the connecting cylinder. The purpose of setting up the various structures and structural connections in this embodiment is at least to combine the roller 10, the link 9, and the connecting rod 1. Figure 3 As shown, the installation of rollers 10 at both ends of link 9 ensures the stability of movement of the inner link segment 91 and the outer link segment 92. The connection between the connecting rod 1 and the rotating shaft 921 also allows the pressure to be mainly concentrated on the rollers 10, reducing the pressure on the unsupported part in the middle of the plate and improving the structural strength of the device.

[0037] Example 8: To increase the connection stability between the rotating column 3 and the sleeve 2, improvements were made based on Example 4, such as... Figure 1 As shown, in this embodiment, the rotating column 3 includes a small diameter section 31 and a large diameter section 32. The small diameter section 31 is inserted into the sleeve 2 and connected to the sleeve 2. The large diameter section 32 is connected to the small diameter section 31, and the bottom wall of the large diameter section 32 abuts against the top wall of the sleeve 2.

[0038] In the specific implementation process, since the rotating column 3 is used to support the object to be sprayed, it will be subjected to a certain pressure. The pressure on the connecting parts between the two, such as the spring pin, can be reduced by the contact action between the large diameter section 32 and the sleeve 2.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
