Description

Technical Field

[0001] This utility model relates to the field of parts spraying tooling technology, specifically a rotary clamp for spraying ring-shaped parts. Background Technology

[0002] Ring-shaped part fixtures are tooling equipment specifically used to fix and position ring-shaped parts (such as bearing sleeves, flanges, annular shells, and other hollow annular structures). Their core function is to ensure that the ring-shaped parts maintain a stable posture during processing and to prevent them from shifting or deforming.

[0003] In the process of spraying annular parts, traditional fixtures have problems such as poor clamping adaptability and low clamping efficiency: a single fixture can only be adapted to parts of fixed specifications and cannot be compatible with annular parts of different inner diameters; the clamping process is cumbersome and requires manual adjustment of the clamping position, which affects the batch processing efficiency; therefore, it is necessary to design a rotary fixture for spraying annular parts to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rotary fixture for spraying annular parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary fixture for spraying annular parts, comprising a base, a rotary table, a rotary drive mechanism, and a clamping mechanism. A stepper motor is installed on one side of the base near the top, and its output end extends to the outside of the base and is connected to the rotary table. Three sets of rotating seats are evenly distributed circumferentially on one side of the rotary table, and all of them are connected to the rotary table through the rotary drive mechanism. The clamping mechanism is located on the other side of the rotating seats.

[0006] Preferably, the rotary drive mechanism includes a drive motor. Three cavities are provided on one side of the rotary table near the edge. A rotating shaft is rotatably connected to the inner side of each cavity, with one end extending to the outside of the rotary table and fixedly connected to one side of the rotating seat. A driven gear is sleeved on the outer ring. The driven gear meshes with a driving gear rotatably connected to the inner side of the cavity. The drive motor is installed on the outer side of the cavity, with its output end extending into the interior of the cavity and connected to the driving gear.

[0007] Preferably, the clamping mechanism includes an L-shaped clamping block. A fixed plate is provided on one side of the rotating seat, on which three sets of circumferentially distributed movable grooves are formed. A drive shaft is rotatably connected to the inner side of the rotating seat, with one end extending to one side of the fixed plate and connected to an adjusting plate. The adjusting plate has three sets of arc-shaped abutment grooves. Three sets of slide rails are provided circumferentially on the outer side of the rotating seat and a slider is slidably connected to them. A connecting shaft is provided on one side of the slider, with one end passing through the inner side of one set of arc-shaped abutment grooves and one set of movable grooves and connected to the L-shaped clamping block.

[0008] Preferably, a slide is provided on the inner side of the rotating seat near the drive shaft, on which a rack plate is slidably connected. One end of the rack plate is connected to an electric telescopic rod installed on the inner side of the rotating seat, and the other end meshes with a circular gear sleeved on the outer ring of the drive shaft.

[0009] Preferably, the contact surface between the L-shaped clamp and the annular part is provided with a rubber pad, and the surface of the rubber pad is provided with an anti-slip texture.

[0010] Preferably, four sets of auxiliary wheels are evenly distributed circumferentially on one side of the base, and the wheel surfaces of the auxiliary wheels are in rolling contact with one side of the rotary table.

[0011] Preferably, the bottom of the base is provided with a mounting plate, and the mounting plate has four sets of waist-shaped mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a stepper motor on one side of the base to drive the entire rotary table to rotate, realizing the switching of the work position of the rotating seat. At the same time, each group of rotating seats can rotate at a uniform speed with the help of the rotation drive mechanism, and the clamping mechanism can firmly clamp the ring-shaped parts. Ultimately, the parts can rotate at a uniform speed with the rotating seats and switch work positions with the rotary table. This ensures that the surface of the parts is fully exposed to the spraying medium to achieve uniform spraying, and can also clamp multiple parts at the same time to carry out continuous spraying operations. It has both spraying uniformity and high efficiency, and greatly improves processing efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please refer to Figure 1-4 As shown, this utility model provides a rotary fixture for spraying annular parts, including a base 1, a rotary table 5, a rotary drive mechanism and a clamping mechanism. A stepper motor 4 is installed on one side of the base 1 near the top, and its output end extends to the outside of the base 1 and is connected to the rotary table 5. Three sets of rotating seats 12 are evenly distributed circumferentially on one side of the rotary table 5, and all of them are connected to the rotary table 5 through the rotary drive mechanism. The clamping mechanism is located on the other side of the rotating seats 12.

[0017] Specifically, after the stepper motor 4 on one side of the base 1 is started, its output end can drive the rotary table 5 to rotate as a whole, causing one set of rotating seats 12 to rotate to the work position. At the same time, the three sets of rotating seats 12 can rotate at a constant speed through the rotation drive mechanism. The clamping mechanism on the other side of the rotating seat 12 can clamp the ring-shaped parts. Finally, the parts are rotated at a constant speed with the rotating seat 12 and the work position is switched with the rotary table 5, ensuring that the surface of the parts is fully exposed to the spraying medium during the spraying process and that continuous operation is possible. Thus, through the above structure, both uniform spraying of the ring-shaped parts and simultaneous clamping of multiple parts are achieved to facilitate continuous spraying operations, thereby improving processing efficiency.

[0018] The rotary drive mechanism includes a drive motor 11. Three cavities 7 are provided on one side of the rotary table 5 near the edge. A rotating shaft 8 is rotatably connected to the inner side of the cavity 7. One end of the shaft extends to the outside of the rotary table 5 and is fixedly connected to one side of the rotating seat 12. A driven gear 9 is sleeved on the outer ring. The driven gear 9 meshes with the driving gear 10 rotatably connected to the inner side of the cavity 7. The drive motor 11 is installed on the outer side of the cavity 7. Its output end extends to the inside of the cavity 7 and is connected to the driving gear 10. When the drive motor 11 on the outer side of the cavity 7 is started, its output end can drive the driving gear 10 on the inner side of the cavity 7 to rotate. The driving gear 10 meshes with the driven gear 9 on the outer ring of the rotating shaft 8, which can drive the rotating seat 12 connected to one end of the rotating shaft 8 to rotate synchronously. This can achieve uniform rotation of the rotating seat 12 and the parts, thereby effectively improving the uniformity of the coating of the parts.

[0019] The clamping mechanism includes an L-shaped clamping block 21. A fixed plate 13 is provided on one side of the rotating seat 12, on which three sets of circumferentially distributed movable grooves 14 are opened. A drive shaft 15 is rotatably connected to the inner side of the rotating seat 12, with one end extending to one side of the fixed plate 13 and connected to an adjusting plate 16. The adjusting plate 16 has three sets of arc-shaped contact grooves 17. Three sets of slide rails 18 are provided circumferentially on the outer side of the rotating seat 12 and are slidably connected to sliders 19. A connecting shaft 20 is provided on one side of the slider 19, with one end passing through the inner side of a set of arc-shaped contact grooves 17 and a set of movable grooves 14 and connected to the L-shaped clamping block 21. A slide 25 is provided on the inner side of the rotating seat 12 near the drive shaft 15, on which a rack plate 24 is slidably connected. One end of the rack plate 24 is connected to an electric telescopic rod 26 installed on the inner side of the rotating seat 12, and the other end is sleeved on the outer ring of the drive shaft 15. The circular gear 23 meshes with the L-shaped clamping block 21, and the contact surface between the L-shaped clamping block 21 and the annular part is provided with a rubber pad 22. The surface of the rubber pad 22 is provided with anti-slip texture. When the electric telescopic rod 26 inside the rotating seat 12 is activated, it can drive the rack plate 24 on the slide 25 to slide. The rack plate 24 meshes with the circular gear 23 on the outer ring of the drive shaft 15, which can drive the drive shaft 15 to drive the adjusting plate 16 to rotate. The arc-shaped abutment groove 17 on the adjusting plate 16 can push the slider 19 to slide along the slide rail 18 on the outer side of the rotating seat 12 through the connecting shaft 20. This can drive the connecting shaft 20 to move synchronously through the L-shaped clamping block 21 connected by the movable groove 14, thereby achieving the clamping of the annular part. The rubber pad 22 on the contact surface of the L-shaped clamping block 21 can enhance the clamping stability. Thus, by setting it up, the clamping stability of the annular part is guaranteed, and the clamping efficiency and adaptability are improved.

[0020] Among them, four sets of auxiliary wheels 6 are evenly distributed on one side of the base 1. The wheel surface of the auxiliary wheels 6 rolls in contact with one side of the rotary table 5. The four sets of auxiliary wheels 6 evenly distributed on one side of the base 1 roll in contact with one side of the rotary table 5, which can provide stable support for the rotary table 5, reduce shaking during rotation, and improve rotational stability and overall structural stability of the fixture.

[0021] The base 1 has a mounting plate 2 at its bottom, and four sets of waist-shaped mounting holes 3 are provided on the mounting plate 2. The four sets of waist-shaped mounting holes 3 on the mounting plate 2 at the bottom of the base 1 can flexibly adjust the installation position of the clamp at the spraying station, adapt to different installation scenarios, and the installation is convenient and stable.

[0022] Working principle: First, the base 1 is fixed to the spraying station through the four sets of waist-shaped mounting holes 3 on the mounting plate 2. The electric telescopic rod 26 inside the rotating seat 12 is activated, which can drive the rack plate 24 on the slide 25 to slide. The rack plate 24 meshes with the circular gear 23 on the outer ring of the drive shaft 15, which can drive the drive shaft 15 to drive the adjusting plate 16 to rotate. The arc-shaped contact groove 17 of the adjusting plate 16 can push the slider 19 to slide along the slide rail 18 through the connecting shaft 20, which can drive the L-shaped clamping block 21 to move synchronously. The ring-shaped part can be clamped through the rubber pad 22. Then, the stepper motor on one side of the base 1 is activated. Machine 4 can drive the rotary table 5 to rotate as a whole and switch a rotating seat 12 with parts to the spraying station. At the same time, the drive motor 11 is started, and its output end can drive the drive gear 10 to rotate, which meshes with the driven gear 9 on the outer ring of the rotating shaft 8. This allows the rotating shaft 8 to drive the rotating seat 12 and the parts to rotate at a uniform speed. The four sets of auxiliary wheels 6 on one side of the base 1 can also provide stable support for the rotary table 5, ensuring that the parts are sprayed from all directions during uniform rotation. After the spraying is completed, the stepper motor 4 can drive the rotary table 5 to switch to the next station, realizing continuous operation and thus completing the entire operation process.
