[0033] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments is not a limitation to the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings.
[0034] An embodiment of the present utility model provides a spraying shielding tooling, which is used to shield a part of the surface of a workpiece 01 during the spraying process of the workpiece 01, so that only a part of the surface of the workpiece 01 can be sprayed. In the whole process, the process of manually pasting a shielding object on the workpiece 01 is avoided, the spraying efficiency is improved, and the labor intensity of workers is reduced. As Figures 1-5 shown, a spraying shielding tooling provided by an embodiment of the present utility model is composed of a base 100, two side plates 200, a shielding plate 300 and a limiting plate 400, so as to position the workpiece 01 on the base 100. The shielding plate 300 shields a part of the surface of the workpiece 01. At the same time, while the shielding plate 300 shields the workpiece 01, the workpiece 01 can be further fixed to ensure that the workpiece 01 is in a stable state and the spraying process can be carried out smoothly. Among them, the base 100 provides a placement surface 101 for placing the workpiece 01, and a number of positioning holes 102 adapted to the positioning posts on the workpiece 01 are opened on the placement surface 101. After the workpiece 01 is placed on the placement surface 101, the positioning posts on the workpiece 01 can just be clamped in the positioning holes 102, so that the workpiece 01 can be stably arranged on the placement surface 101; the side plates 200 are two and are arranged on the placement surface 101 at intervals respectively, and define a placement area 201 for clamping and fixing the workpiece 01. After the workpiece 01 is placed on the base 100, the two opposite surfaces of the workpiece 01 are positioned by the side plates 200, so that the workpiece 01 can be placed in the placement area 201 defined by the two side plates 200, and the workpiece 01 is further positioned and fixed by the side plates 200, so as to further improve the stability of the workpiece 01; the shielding plate 300 is detachably arranged on the placement surface 101 and shields a part of the placement area 201, and a spacing space for placing the workpiece 01 is arranged between the shielding plate 300 and the placement surface 101; the limiting plate 400 is detachably arranged on the base 100 and is correspondingly arranged at the other end of the placement area 201 relative to the shielding plate 300, so as to fix the workpiece 01 in the placement area 201.
[0035] The workpiece 01 is placed within the placement area 201, where two sides are limited and fixed by the side plates 200, and the other side is fixed by the limit plate 400. At the same time, the shielding plate 300 is buckled on a part of the surface of the workpiece 01 by covering. Since there is a spaced space between the shielding plate 300 and the placement surface 101, the workpiece 01 can be restricted within this spaced space to avoid jumping, and then the workpiece 01 is stably installed within the placement area 201. And the part of the surface of the workpiece 01 is shielded by the shielding plate 300. During the spraying process of the workpiece 01, the workpiece 01 can be quickly installed and shielded, thus avoiding the process of pasting shielding objects on the workpiece 01, greatly improving the spraying efficiency of the workpiece 01, and at the same time greatly reducing the labor intensity of the workers.
[0036] In this embodiment, as Figure 5 shown, the shielding plate 300 includes a plate body 301, a pressing member 303 and a limiting member 304. The plate body 301 is used to cover the upper side of the placement area 201 to shield a part of the placement area 201, and a lapping portion 302 is provided on the plate body 301 and lapped on the two side plates 200; the pressing member 303 is formed on the side surface of the plate body 301 facing the placement area 201, and the width dimension of the pressing member 303 is adapted to the interval dimension between the two side plates 200, so that the pressing member 303 is just embedded between the two side plates 200; the limiting member 304 is correspondingly arranged on the side surface of the plate body 301 facing the placement area 201, and an accommodation groove 305 for receiving the end of the workpiece 01 is arranged at intervals between the limiting member 304 and the pressing member 303.
[0037] During the process of covering the shielding plate 300 over the placement area 201 to shield and fix the workpiece 01, the plate body 301 is laid on the side plate 200 through the overlapping parts 302 formed on both sides. At the same time, the pressing member 303 presses the workpiece 01 towards the placement surface 101 direction, thereby preventing the workpiece 01 from jumping in the vertical direction. It can be thought that the workpiece 01 is pressed and fixed by the gravity of the shielding plate 300. Since during the spraying process, the tooling and the workpiece 01 are in a relatively fixed state, therefore, the external force received by the workpiece 01 is mainly the vibration during the operation of the equipment. The gravity of the shielding plate 300 can overcome the vibration during the equipment operation and stably press the workpiece 01. At the same time, during the process of pressing the workpiece 01, the plate body 301 shields a part of the surface of the workpiece 01, so that spraying processing can be carried out only on the open surface of the workpiece 01. When the plate body 301 is placed within the placement area 201, the limiting member 304 is located at the end position of the workpiece 01. Since most of the ends of the workpiece 01 are provided with bent parts, therefore, the bent part at the end of the workpiece 01 can be embedded into the receiving groove 305, so that during the process of the shielding part shielding and clamping the workpiece 01, it can be in a horizontal state, thus being able to tightly shield the workpiece 01.
[0038] In this embodiment, a limiting groove 306 adapted to the end of the workpiece 01 is provided at the bottom of the receiving groove 305. The limiting groove 306 has a width dimension adapted to the thickness of the workpiece 01. In order to make the pressing of the workpiece 01 more stable and be able to position the workpiece 01 at the same time, after covering the shielding plate 300 over the workpiece 01, the upward-bent part of the workpiece 01 can be just stuck into the limiting groove 306. Since during the design process, the width dimension of the limiting groove 306 is designed to be adapted to the thickness dimension of the workpiece 01, thus after the bent part of the workpiece 01 is stuck into the limiting groove 306, accurate positioning and fixing of the workpiece 01 can be ensured.
[0039] In this embodiment, in order to lift or cover the shielding plate 300 downward, a handheld part is formed on the end face of the plate body 301 facing away from the placement area 201 for lifting the shielding plate 300. By holding the main handheld part (not shown in the figure), the shielding plate 300 can be lifted conveniently and smoothly, thus facilitating the operation of it.
[0040] In this embodiment, as Figures 1-4As shown, a placement boss 110 is formed on the base 100. The top surface of the placement boss 110 defines a placement surface 101, and the sides of the two side plates 200 are respectively in contact with the sides of the placement boss 110. By providing a placement boss 110, when the workpiece 01 is placed on the boss 110, the end portion of the workpiece 01 that folds downward can extend downward along the descending step of the boss 110, making the workpiece 01 more stable during placement and avoiding instability.
[0041] In this embodiment, the limiting plate 400 has a long strip plate structure and a height dimension higher than that of the placement boss 110. A quick clamp corresponding to the limiting plate 400 is also provided on the base 100. The quick clamp is used to press the limiting plate 400 toward the placement boss 110. After the workpiece 01 is placed on the boss 110, the limiting plate 400 is pressed against the side of the boss 110 by the quick clamp, so that the workpiece 01 can be clamped, improving the reliability of positioning and fixing the workpiece 01.
[0042] To facilitate the removal of the workpiece 01 from the placement area 201 after the spraying process is completed, a notch 111 is formed on the side of the placement boss 110 facing the limiting plate 400. The notch 111 causes the workpiece 01 placed on the placement surface 101 to have a suspended portion. When the workpiece 01 needs to be removed from the placement boss 110, after the worker's hand reaches into the notch 111, the suspended portion of the workpiece 01 is lifted, and thus the workpiece 01 is removed from the placement area 201. It should be noted that since the workpiece 01 is fixed by the side plates 200 and the positioning holes 102 in the placement area 201, during the process of removing the workpiece 01 from the placement area 201, an upward force needs to be applied to the workpiece 01. By reaching the hand into the notch 111, the suspended portion of the workpiece 01 can be easily pulled upward, and the workpiece 01 can be quickly and conveniently removed from the placement area 201.
[0043] Meanwhile, in order to ensure the stable placement of workpiece 01 on the boss 110, a number of avoidance positions 112 adapted to the workpiece 01 are provided on the boss 110. In addition, a number of card slots 202 adapted to the bent portions of the workpiece 01 are provided on the top surface of at least one side plate 200 to clamp the bent portions of the workpiece 01 to each other. Through the avoidance positions 112 and the card slots 202, the protruding portions on the workpiece 01 can be embedded therein. In particular, when the bent portion of the workpiece is lapped on the side plate 200, the bent portion can be clamped in the card slots 202. Firstly, the bent portion can be accommodated, and at the same time, through the mutually clamped card slots 202 and the bent portion, the stability of the workpiece 01 placed in the placement area 201 can be further improved, ensuring the smooth spraying process of the workpiece 01.
[0044] Through the spraying shielding tooling provided by this embodiment, during the spraying process of the workpiece 01, the workpiece 01 can be quickly fixed in the placement area 201, and the workpiece 01 can be stably and reliably positioned and fixed by the side plate 200 and the limiting member 304, so that the workpiece 01 remains in a fixed state. The shielding plate 300 covers the placement area 201, thereby shielding part of the surface of the workpiece 01. During the shielding process of the workpiece 01, the bent portion at the end of the workpiece 01 can be accommodated and fixed, thereby further fixing the workpiece 01. And by gravity, the workpiece 01 is pressed against the placement boss 110 to prevent the workpiece 01 from jumping in the vertical direction. Through the spraying shielding tooling provided by this embodiment, the workpiece 01 can be reliably positioned and fixed, and part of the surface of the workpiece 01 can be quickly and effectively shielded, thus avoiding the work of manually pasting shielding materials on the workpiece 01, greatly improving the production efficiency of the spraying process of the workpiece 01 and greatly reducing the labor intensity of the workers.
[0045] The above are only preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention is disclosed above in preferred embodiments, it is not intended to limit the present invention.
