Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive sealing strip technology, specifically relating to a composite placement and spraying fixture for automotive B-pillar and C-pillar sealing strips. Background Technology
[0002] Generally, automotive B-pillar and C-pillar sealing strips have specific surface coating requirements. During spraying, a fixture is needed to position the product, ensuring the sprayed surface is within reach of the spray gun and that the paint covers the entire surface. Conventional spraying fixtures, which arrange the products in the same direction, meet these requirements. However, for automotive B-pillar sealing strips, which are wider at the top than the bottom, and C-pillar sealing strips, which are arranged in a Z-shape, arranging them sequentially in the same direction results in significant spacing between the products. This leads to longer spraying times and paint waste. While conventional spraying fixtures, which arrange the products in the same direction, can still meet the coating requirements, the large spacing between products, limited fixture components, and low load-bearing capacity result in a smaller number of products being sprayed per unit time, with paint being sprayed much more evenly between the products, leading to substantial paint waste. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a composite placement and spraying fixture for automotive B-pillar and C-pillar sealing strips, which can solve problems such as long spraying time and excessive paint waste, in light of the current state of the technology.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a composite placement and spraying fixture for automotive B-pillar and C-pillar sealing strips, characterized in that it includes a main body, the main body including a left B-pillar fixture base and a right B-pillar fixture base located on both sides and a C-pillar fixture base located in the middle, the left B-pillar fixture base is provided with at least one set of left upright mounting bracket and left inverted mounting bracket, the left upright mounting bracket and left inverted mounting bracket are alternately placed on the left B-pillar fixture base, the right B-pillar fixture base is provided with at least one set of right upright mounting bracket and right inverted mounting bracket, the right upright mounting bracket and right inverted mounting bracket are alternately placed on the right B-pillar fixture base, the upper part of the C-pillar fixture base is provided with a C-pillar left upright mounting bracket and a C-pillar left inverted mounting bracket, and the lower part of the C-pillar fixture base is provided with a C-pillar right upright mounting bracket and a C-pillar right inverted mounting bracket.
[0005] In the aforementioned composite placement and spraying fixture for automotive B-pillar and C-pillar sealing strips, the left B-pillar fixture base, the right B-pillar fixture base, and the C-pillar fixture base all include a square tube frame and a positioning pin. The square tube frame is made of welded stainless steel square tubes, and the positioning pin is inserted into the chassis of the equipment to be sprayed.
[0006] In the aforementioned composite placement and spraying fixture for automotive B-pillar and C-pillar sealing strips, when the left B-pillar fixture base is filled with B-pillar left component products and placed on the left side of the fixture chassis, when the right B-pillar fixture base is filled with B-pillar right component products and placed on the right side of the fixture chassis, and when the C-pillar fixture base is filled with C-pillar left and right component products and placed in the middle of the fixture chassis, the fixture base is filled with C-pillar left and right component products.
[0007] Compared with the existing technology, the advantages of this utility model are that the products are placed upside down and spaced apart, left and right parts are mixed, and B and C pillars are mixed. Through the combination of B and C pillars, left and right parts, formal and informal styles, the products are placed more densely, the product spraying area is more concentrated, the spray gun travels less and takes less time, and the paint sprayed by the spray gun is sprayed less in the non-product area and more effectively sprayed on the product surface, thus improving spraying efficiency and saving spraying paint. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the composite placement and spraying fixture structure for the B-pillar and C-pillar sealing strips of this automobile. Detailed Implementation
[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0010] In the diagram, the main body is 100; the left B-pillar fixture base is 200; the right B-pillar fixture base is 300; the C-pillar fixture base is 400; the square tube frame is 500; the positioning pin is 600; the left upright bracket is 700; the left inverted bracket is 800; the right upright bracket is 900; the right inverted bracket is 1000; the left upright bracket of the C-pillar is 1001; the left inverted bracket of the C-pillar is 1002; the right upright bracket of the C-pillar is 1003; and the right inverted bracket of the C-pillar is 1004.
[0011] like Figure 1 As shown, this automotive B-pillar and C-pillar sealing strip composite placement spraying fixture includes a main body 100. The main body 100 includes a left B-pillar fixture base 200 and a right B-pillar fixture base 300 located on both sides, and a C-pillar fixture base 400 located in the middle. The left B-pillar fixture base 200, the right B-pillar fixture base 300, and the C-pillar fixture base 400 all include a square tube frame 500 and a positioning pin 600. The square tube frame 500 is made of welded stainless steel square tubes. The positioning pin 600 is inserted into the chassis of the equipment to be sprayed. The square tube frame 500 and the positioning pin 600 can ensure the reliable positioning of the entire fixture.
[0012] Specifically, the left B-pillar fixture base 200 is equipped with at least one set of left forward mounting brackets 700 and left inverted mounting brackets 800. These brackets are alternately placed on the left B-pillar fixture base 200, thus improving the fixture loading rate. Similarly, the right B-pillar fixture base 300 is equipped with at least one set of right forward mounting brackets 900 and right inverted mounting brackets 1000. These brackets are alternately placed on the right B-pillar fixture base 300, again achieving alternating forward and inverted mounting on the right side, further improving the fixture loading rate. The C-pillar fixture base... The upper part of the C-pillar fixture base 400 is equipped with a C-pillar left upright bracket 1001 and a C-pillar left inverted bracket 1002. The lower part of the C-pillar fixture base 400 is equipped with a C-pillar right upright bracket 1003 and a C-pillar right inverted bracket 1004. When the left B-pillar fixture base 200 is filled with B-pillar left parts, it is placed on the left side of the fixture base. When the right B-pillar fixture base 300 is filled with B-pillar right parts, it is placed on the right side of the fixture base. The C-pillar fixture base 400 is filled with C-pillar left and right parts and is placed in the middle of the fixture base. In this way, the left and right parts of the B-pillar and C-pillar, as well as the upright and inverted parts, are arranged in a composite manner, resulting in a denser product placement and a more concentrated product spraying area. The spray gun travels less and for a shorter time, and less paint is sprayed onto areas without products, resulting in more effective spraying on the product surface, improving spraying efficiency and saving paint.
[0013] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope defined by the spirit of this utility model.
