Description

Technical Field

[0001] The present invention belongs to the field of tooling, and particularly relates to a painting tooling for annular workpieces. Background Art

[0002] In the prior art, when spraying an annular workpiece, the workpiece needs to be first clamped to a positioning seat and then sprayed. During the spraying process, due to the limitation of the operation position and space, the bottom surface of the workpiece cannot be effectively sprayed. Usually, the workpiece needs to be removed from the positioning seat and flipped, and then re-positioned and installed. The workpiece is not easy to flip, the painting is inconvenient, and the operation is cumbersome during the whole painting operation process, and the work efficiency is low. At the same time, most of the positioning seats can only clamp workpieces with the same inner diameter specification and cannot well meet the installation and positioning requirements of different workpieces. Therefore, it is necessary to improve the existing painting tooling. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0024] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0025] A painting tooling for annular workpieces, as Figures 1 to 5 shown, includes a workbench 1. A support frame 2 is provided on the workbench. The support frame is located on one side of the workbench. A workpiece positioning frame 3 is installed on the support frame. Walking wheels 4 are symmetrically provided at the bottom of the workbench. By way of example, the walking wheels are universal wheels with a self-locking device. The workpiece positioning frame includes a base body 5. Three support arms 6 are evenly distributed around the outer periphery of the base body. Support seats 7 are installed at the ends of the support arms. Generally, connecting arms 18 are provided between every two adjacent support arms to improve the structural stability of the workpiece positioning frame. With the walking wheels at the bottom of the workbench, the painting tooling can be conveniently moved.

[0026] A seat plate 8 is detachably installed on the support seat. In an optional embodiment, as Figure 5 shown, several threaded connecting rods 16 are provided on the lower side of the seat plate. Corresponding through holes are provided on the support seat for each connecting rod. One end of the connecting rod passing through the support seat is locked by a nut 17. The seat plate adopts a detachable structural design. By installing a seat plate with a suitable thickness according to actual needs, the clamping requirements of different workpieces can be adapted, with good versatility and effectively ensuring the workpiece clamping and positioning effect.

[0027] Meanwhile, a positioning plate 9 is provided on one side of the support base close to the support frame, and a workpiece pressing device 10 is installed on the side of the support base different from the side where the positioning plate is provided. Usually, the positioning plate and the support base are of an integrally formed structure. A bearing seat 11 is installed on the support frame, and a rotating shaft 12 is rotatably installed in the bearing seat. The base body is installed at one end of the rotating shaft extending out of the support frame. A backing plate 13 is laid on the upper end of the workbench and the upper end of the support frame. By way of example, the backing plate is made of an aluminum plate with patterns or a steel plate with patterns. Two bearing seats are provided at the top of the support frame, and the rotating shaft is rotatably engaged with both of the two bearing seats at the same time.

[0028] In an alternative embodiment, the workpiece pressing device is provided with a pressing mechanism for pressing the workpiece. The pressing mechanism includes a pressing rod 14, and a conical working head 15 is provided at the end of the pressing rod. The small-diameter end of the working head faces the side of the seat plate. Usually, the working head corresponds to the edge position of the seat plate (on the side away from the positioning plate). As long as it can press the edge of the workpiece, when the working head in front of the pressing rod presses the workpiece through the handle drive, the area covering the surface of the workpiece is very small. While ensuring the stability of clamping and fixing, it does not affect the painting effect. By way of example, the workpiece pressing device includes a quick-clamping press. Of course, those skilled in the art can also adopt workpiece pressing devices with other structural forms according to needs, as long as the workpiece can be pressed and fixed on the workpiece positioning frame (seat plate).

[0029] During application, the annular workpiece is sleeved outside the support base of the workpiece positioning frame, supported by the seat plate and limited by the positioning plate, and then the end of the workpiece different from the positioning plate is pressed by the workpiece pressing device, thus completing the clamping and fixing of the workpiece. Manually rotating the workpiece positioning frame can realize the rotational adjustment of the annular workpiece. During the painting operation, the worker only needs to stand at the same position on the workbench to complete the spraying of all surfaces of the workpiece.

[0030] The structure of the present invention is simple and reasonably designed. The rotating shaft is rotatably installed on the support frame, and the workpiece positioning frame is installed at one end of the rotating shaft extending out of the support frame, so that the workpiece positioning frame can be rotationally adjusted relative to the support frame. The annular workpiece is directly clamped outside the support base of the workpiece positioning frame and fixed by the workpiece pressing device, and the structure is stable and reliable. During the painting process, the rotational adjustment of the painting position of the annular workpiece can be realized by rotating the workpiece positioning frame. The worker can spray the entire surface of the annular product without moving at one position, reducing product turnover and personnel movement, saving time and effort, having high work efficiency, and ensuring the quality of the painting operation.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
