Description

Technical Field

[0001] The utility model belongs to the technical field of thermal spraying, and in particular relates to a thermal spraying rotating frame with a protective structure. Background Art

[0002] Thermal spraying is a process of heating and melting the coating material, atomizing it into extremely fine particles with a high-speed airflow, and spraying it onto the surface of the workpiece at a very high speed to form a coating. Therefore, thermal spraying produces more noise, and due to the heating, it produces strong light, which can cause noise and light damage to the operator.

[0003] In the prior art, a Chinese patent with a reference number of CN 114481000 A discloses a powder thermal spraying rotating frame with a protective function, wherein the rotating frame comprises an upper rotating table and a lower rotating table, a rotating rod is arranged between the upper and lower rotating tables, at least two protective plates are arranged on the peripheral side of the rotating frame extending radially outward, and the protective plates and the rotating frame enclose a protective area. The utility model can protect operating personnel from strong light, noise and dust pollution generated during spraying, and at the same time protect equipment from dust erosion, thereby creating a safe operating environment.

[0004] The comparative document provides a thermal spraying rotating frame with a protective structure, but the above patent only realizes elastic extrusion of the workpiece in the axial direction when fixing the sprayed workpiece. When the sprayed workpiece needs to be rotated, there will be a problem that the axial extrusion force is insufficient, resulting in the sprayed workpiece being unable to rotate. The clamping firmness is low, which makes it inconvenient to perform all-round thermal spraying on the sprayed parts.

[0005] Therefore, a thermal spraying rotating frame with a protective structure is proposed. Utility Model Content

[0008] Preferably, a thermal spraying rotating frame with a protective structure also includes a first baffle and a second baffle fixed by bolts between the chassis and the top plate at the outer positions close to the lower fixed sleeve and the upper fixed sleeve, the first baffle being located on one side of the second baffle; a slider welded to the bottom of the chassis; and a slide groove opened on the top of the base.

[0009] Preferably, the lower fixing sleeve and the upper fixing sleeve are both hollow cylindrical structures with one side open.

[0010] Preferably, the cross section of the spring sheet is arc-shaped.

[0011] Preferably, the spring sleeve is arranged on the outside of the T-shaped rod.

[0012] Preferably, the included angle between the first baffle and the second baffle is degrees.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] The bottom end of the cylindrical workpiece is clamped by the rebound force of the spring sheet, so that the cylindrical workpiece is fixed in the radial direction, ensuring that the cylindrical workpiece has a sufficiently large friction force when rotating, thereby ensuring smooth rotation of the cylindrical workpiece, and achieving all-round thermal spraying of the outer side of the cylindrical workpiece. By shielding the first baffle and the second baffle, strong light can be prevented from directly shining into the eyes of the operator, reducing damage to the operator.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides a thermal spraying rotating frame with a protective structure, such as Figure 1-5 As shown, it includes a base 1, a first motor 2 is fixedly connected to the bottom center of the base 1 by bolts, the output end of the first motor 2 is fixedly connected to the chassis 3, a support column 4 is welded to the top center of the chassis 3, a top plate 5 is welded to the top of the support column 4, a second motor 66 in a columnar workpiece fixing assembly 6 is fixedly connected to the bottom of the chassis 3 by bolts, the output end of the second motor 66 is fixedly connected to a lower fixing sleeve 61, a T-shaped rod 62 passes through the top of the top plate 5, an upper fixing sleeve 63 is welded to the bottom end of the T-shaped rod 62, and a top of the upper fixing sleeve 63 and a bottom of the top plate 5 are connected. A spring 64 is provided at an outer position near the T-shaped rod 62, and spring sheets 65 are embedded in the inner walls of the lower fixing sleeve 61 and the upper fixing sleeve 63. A first baffle 71 and a second baffle 72 are fixedly connected by bolts at an outer position near the cylindrical workpiece fixing assembly 6 between the chassis 3 and the top plate 5. The first baffle 71 is located on one side of the second baffle 72, and the angle between the first baffle 71 and the second baffle 72 is 90 degrees. A slider 8 is welded to the bottom of the chassis 3, and a slide groove 9 is provided on the top of the base 1. The slider 8 is located inside the slide groove 9, and the slider 8 and the slide groove 9 are slidably connected.

[0025] It should be noted that, since the existing spray-coated workpiece only realizes elastic extrusion of the workpiece in the axial direction when it is fixed, when the spray-coated workpiece needs to be rotated, there will be a problem that the axial extrusion force is insufficient and the spray-coated workpiece cannot be rotated, and the clamping firmness is relatively low. In this embodiment, the bottom end of the cylindrical workpiece is clamped by the rebound force of the spring sheet 65, so that the cylindrical workpiece is fixed in the radial direction, and it is ensured that the cylindrical workpiece has a sufficiently large friction force when rotating, thereby ensuring the smooth rotation of the cylindrical workpiece, and realizing all-round thermal spraying of the outer side of the cylindrical workpiece. Through the shielding of the first baffle 71 and the second baffle 72, strong light can be prevented from directly shining into the eyes of the operator, thereby reducing damage to the operator.

[0026] Specifically, in the present embodiment, the present scheme mainly comprises a cylindrical workpiece fixing assembly 6 and a protection assembly 7. Before thermal spraying of the cylindrical workpiece, the upper fixing sleeve 63 is pushed upward. The upper fixing sleeve 63 squeezes the spring 64 during the upward movement. The spring 64 is compressed by force, and the distance between the upper fixing sleeve 63 and the lower fixing sleeve 61 becomes larger. The bottom end of the cylindrical workpiece is inserted into the lower fixing sleeve 61, and the spring sheet 65 is squeezed on the outer wall of the cylindrical workpiece. The spring sheet 65 is deformed by force, and the bottom end of the cylindrical workpiece is clamped by the rebound force of the spring sheet 65. After the cylindrical workpiece is placed vertically, the upper fixing sleeve 63 is released. Under the action of the rebound force of the spring 64, the upper fixing sleeve 63 moves downward and is sleeved on the cylindrical workpiece. The top of the workpiece is used to clamp and fix the cylindrical workpiece, and the thermal spraying equipment is placed on one side of the rotating frame. When thermal spraying is performed, the spraying equipment sprays the spray material to the outer wall of the cylindrical workpiece, and the second motor 66 drives the lower fixed sleeve 61 to rotate through its output end, and the cylindrical workpiece between the lower fixed sleeve 61 and the upper fixed sleeve 63 rotates synchronously to achieve all-round spraying of the cylindrical workpiece. After completing the spraying of a cylindrical workpiece, the first motor 2 drives the chassis 3 to rotate 90 degrees through its output end, and rotates the other cylindrical workpiece to one side of the spraying equipment. The first baffle 71 and the second baffle 72 are used to block the strong light from directly hitting the operator's eyes, thereby reducing damage to the operator.

[0027] In a further preferred embodiment of the present invention, Figure 1 , 2 and Figure 5 As shown, the lower fixing sleeve 61 and the upper fixing sleeve 63 are both hollow cylindrical structures with one side open.

[0028] In this embodiment, the two ends of the cylindrical workpiece can be clamped and fixed, thereby ensuring that the cylindrical workpiece can rotate to adjust the spraying position.

[0029] In a further preferred embodiment of the present invention, Figure 1 , 2 and Figure 5 As shown, the cross section of the spring piece 65 is arc-shaped.

[0030] In this embodiment, the spring sheet 65 can stably clamp the cylindrical workpiece through the elastic deformation ability of the spring sheet 65, thereby ensuring that the cylindrical workpiece can rotate.
