Description

Technical Field

[0001] This utility model relates to the field of inner cylinder spraying technology, and more specifically, to a highly stable inner cylinder spraying connecting shaft clamp. Background Technology

[0002] As a common hollow cylindrical component, the inner cylinder is widely used in many fields such as industrial manufacturing, mechanical equipment, and daily necessities. Since the inner cylinder needs to withstand complex working conditions such as physical friction, chemical corrosion, and high temperature in different environments during use, it is usually necessary to spray the inner wall to improve its wear resistance, corrosion resistance, heat insulation and other properties.

[0003] In traditional inner cylinder spraying operations, clamping devices have many shortcomings: 1. Existing clamps are difficult to adapt to inner cylinders of different sizes, the clamping process is complicated and easily leads to uneven force on the inner cylinder, causing deformation and damage; 2. Spraying methods mostly adopt fixed angles or manual operation, which is not only inefficient, but also prone to problems such as uneven coating thickness and missed spraying, seriously affecting the spraying quality and product performance.

[0004] Therefore, there is an urgent need for a highly stable inner cylinder spraying connecting shaft fixture to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable inner cylinder spraying connecting shaft clamp to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A high-stability inner cylinder spraying connecting shaft clamp includes a worktable, a Z-shaped frame fixedly connected to the outer wall of the worktable, a drive motor A fixedly connected to the outer wall of the Z-shaped frame, a drive motor B also fixedly connected to the outer wall of the Z-shaped frame, a drive gear fixedly connected to the output end of the drive motor A, a fixing plate fixedly connected to the outer wall of the worktable, and a pump fixedly connected to the top wall of the fixing plate. The clamp also includes:

[0008] A clamping assembly includes a sliding groove evenly provided on the outer wall of a worktable, a slider slidably connected to the outer wall of the sliding groove, a clamping block fixedly connected between adjacent sliders, a guide frame fixedly connected to the outer wall of the clamping block, and guide grooves symmetrically distributed on the outer wall of the guide frame.

[0009] A drive assembly is disposed on the outer wall of the worktable, and the drive assembly cooperates with the clamping assembly.

[0010] As a preferred technical solution of this application, the driving assembly includes a hollow screw rotatably connected to the outer wall of the worktable, a lifting block threadedly connected to the outer wall of the hollow screw, a uniformly distributed lifting frame fixedly connected to the outer wall of the lifting block, symmetrically distributed guide rods fixedly connected to the outer wall of the lifting frame, and the guide rods located on the inner wall of the guide groove, and a driven gear fixedly connected to the outer wall of the hollow screw, and the outer wall of the driven gear meshing with the outer wall of the driving gear.

[0011] As a preferred technical solution of this application, the hollow screw is fixedly connected to a base plate at the end away from the worktable, and the base plate is rotatably connected to the hollow screw. The top wall of the base plate is fixedly connected to a uniformly distributed slide rod, and the slide rod is slidably connected to the lifting block. The top wall of the slide rod is fixedly connected to the worktable.

[0012] As a preferred technical solution of this application, a hollow rod is fixedly connected to the output end of the drive motor B, and the hollow rod is rotatably connected to a hollow screw. A dynamic sealing block is rotatably connected to the outer wall of the hollow rod, a connecting pipe is fixedly connected to the outer wall of the dynamic sealing block, and the end of the connecting pipe away from the dynamic sealing block is fixedly connected to the pump outlet. Uniformly distributed nozzles are fixedly connected to the outer wall of the hollow rod.

[0013] As a preferred technical solution of this application, the outer wall of the workbench is fixedly connected with symmetrically distributed support frames, and a support plate is fixedly connected to the end of the support frame away from the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. Through the threaded transmission design of the hollow screw, the clamping blocks can be adjusted over a wide range, quickly adapting to inner cylinder workpieces of different inner diameters without complex adjustments. It is highly flexible and adaptable. At the same time, multiple clamping blocks move synchronously, achieving stable clamping through the guide frame and guide rod, ensuring uniform force on the workpiece, avoiding deformation due to single-point force, effectively protecting the inner cylinder and preventing deformation. The operation is simple, and quick clamping can be completed through motor control, reducing manual intervention and improving work efficiency. It solves the problems of existing fixtures being unable to adapt to inner cylinders of different sizes, and the complex clamping process easily leading to uneven force on the inner cylinder, causing deformation and damage.

[0017] 2. By rotating the spray nozzle with the hollow rod, uniform spraying of the inner cylinder is achieved from all directions, improving spraying efficiency. At the same time, the rotary spraying helps to ensure uniform coating thickness, reducing repetitive work and rework caused by manual spraying or fixed-angle spraying. This improves the spraying quality and the overall aesthetics and practicality of the product. It solves the problem that existing spraying methods often use fixed angles or manual operation, which are not only inefficient but also prone to uneven coating thickness and missed spraying, seriously affecting the spraying quality and product performance.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figure 1-6 As shown, this embodiment proposes a highly stable inner cylinder spraying connecting shaft fixture, including a worktable 1, a Z-shaped frame 4 fixedly connected to the outer wall of the worktable 1, a drive motor A18 fixedly connected to the outer wall of the Z-shaped frame 4, a drive motor B22 also fixedly connected to the outer wall of the Z-shaped frame 4, a drive gear 17 fixedly connected to the output end of the drive motor A18, a fixing plate 12 fixedly connected to the outer wall of the worktable 1, and a pump 24 fixedly connected to the top wall of the fixing plate 12, and further including:

[0028] The clamping assembly includes a slide groove 5 evenly provided on the outer wall of the worktable 1. A slider 6 is slidably connected to the outer wall of the slide groove 5. A clamping block 7 is fixedly connected between adjacent sliders 6. A guide frame 8 is fixedly connected to the outer wall of the clamping block 7. A guide groove 9 is symmetrically distributed on the outer wall of the guide frame 8. The lifting block 15 drives the guide rod 10 to slide in the guide groove 9 through the lifting frame 11, thereby causing the slider 6 to slide in the slide groove 5, and finally realizing the synchronous movement of the clamping block 7 to complete the clamping of the workpiece.

[0029] The drive assembly is located on the outer wall of the worktable 1, and the drive assembly cooperates with the clamping assembly.

[0030] like Figure 5 As shown, in a preferred embodiment, based on the above method, the drive assembly further includes a hollow screw 13 rotatably connected to the outer wall of the worktable 1. A lifting block 15 is threadedly connected to the outer wall of the hollow screw 13. A uniformly distributed lifting frame 11 is fixedly connected to the outer wall of the lifting block 15. A symmetrically distributed guide rod 10 is fixedly connected to the outer wall of the lifting frame 11, and the guide rod 10 is located on the inner wall of the guide groove 9. A driven gear 16 is fixedly connected to the outer wall of the hollow screw 13, and the outer wall of the driven gear 16 meshes with the outer wall of the drive gear 17. When the drive motor A18 starts, it drives the drive gear 17 to rotate. The drive gear 17 meshes with the driven gear 16, causing the hollow screw 13 to rotate. Since the lifting block 15 is threadedly connected to the hollow screw 13, and the slide rod 14 restricts the rotation of the lifting block 15, the lifting block 15 will move linearly along the hollow screw 13. The lifting block 15 drives the guide rod 10 to slide in the guide groove 9 through the lifting frame 11.

[0031] like Figure 5 As shown, in a preferred embodiment, based on the above method, a base plate 19 is fixedly connected to the end of the hollow screw 13 away from the worktable 1, and the base plate 19 is rotatably connected to the hollow screw 13. A uniformly distributed slide rod 14 is fixedly connected to the top wall of the base plate 19, and the slide rod 14 is slidably connected to the lifting block 15. The top wall of the slide rod 14 is fixedly connected to the worktable 1. The drive motor B22 drives the hollow rod 20 to rotate, so that the spray pipe 25 sprays the inner cylinder of the workpiece. Since the hollow rod 20 is rotatably connected to the hollow screw 13, the workpiece can maintain a stable rotation state during the spraying process.

[0032] like Figure 6 As shown, in a preferred embodiment, based on the above method, a hollow rod 20 is fixedly connected to the output end of the drive motor B22, and the hollow rod 20 is rotatably connected to the hollow screw 13. A dynamic sealing block 21 is rotatably connected to the outer wall of the hollow rod 20. A connecting pipe 23 is fixedly connected to the outer wall of the dynamic sealing block 21, and the end of the connecting pipe 23 away from the dynamic sealing block 21 is fixedly connected to the outlet of the pump 24. A uniformly distributed spray pipe 25 is fixedly connected to the outer wall of the hollow rod 20. The pump 24 delivers the paint through the connecting pipe 23 to the dynamic sealing block 21, and then into the hollow rod 20. The connection between the dynamic sealing block 21 and the hollow rod 20 is a dynamic seal.

[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the workbench 1 is further provided with symmetrically distributed support frames 2, and the end of the support frame 2 away from the workbench 1 is fixedly connected with a support plate 3. The equipment is supported and fixed by the support frame 2 and the support plate 3.

[0034] Specifically, when using this highly stable inner cylinder spraying connecting shaft fixture: the drive motor A18 starts, driving the drive gear 17 to rotate. The drive gear 17 meshes with the driven gear 16, causing the hollow screw 13 to rotate. Since the lifting block 15 is threadedly connected to the hollow screw 13, and the slide rod 14 restricts the rotation of the lifting block 15, the lifting block 15 will move linearly along the hollow screw 13. The lifting block 15 drives the guide rod 10 to slide in the guide groove 9 through the lifting frame 11, thereby causing the slider 6 to slide in the slide groove 5, ultimately achieving synchronous movement of the clamping block 7 and completing the clamping of the workpiece. The pump 24 delivers the paint through the connecting pipe 23 to the dynamic sealing block 21, and then into the hollow rod 20. The drive motor B22 drives the hollow rod 20 to rotate, causing the spray pipe 25 to spray the inner cylinder of the workpiece. Since the hollow rod 20 is rotatably connected to the hollow screw 13, the workpiece can maintain a stable rotation state during the spraying process.

[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
