Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and specifically discloses a fixture structure for improving paint burrs. Background Technology

[0002] In industrial production, particularly in consumer electronics and automotive parts, the surface quality requirements for product exterior parts are increasingly stringent. Painting and vacuum electroplating are common surface treatment processes used to provide decorative or functional coatings. These operations typically require specialized fixtures to hold and position the products to ensure processing accuracy and consistency. The structural design of these fixtures directly affects the uniformity of the coating, yield rate, and production efficiency.

[0003] However, a common technical challenge in existing painting or electroplating processes is that, due to the fluidity of the paint or plating solution, it easily flows along the surface of the fixture to the joint edge between the fixture and the product during processing. This leads to unintended accumulation and adhesion of paint at the product edges, forming defects such as "rough edges" or "paint overflow." These defects not only affect the appearance and aesthetics of the product but also often require subsequent manual cleaning and may even lead to product scrapping, thereby increasing production costs and hindering further improvements in production efficiency and product yield. Utility Model Content

[0004] This utility model proposes a fixture structure to improve the rough edges of paint spraying. When painting or electroplating is performed, the paint or plating solution flowing along the surface of the fixture will be effectively intercepted and contained in the groove, which effectively improves the rough edge defects generated on the product during the painting or electroplating process, and significantly improves the appearance quality and yield of the product.

[0005] This utility model is implemented as follows: a fixture structure for improving paint rough edges includes a base, a fixture body is fixedly connected to the center of the upper end face of the base, and a flow-blocking groove is formed on the upper end face of the base along the edge of the fixture body. The flow-blocking groove is used to block and contain paint or plating solution flowing towards the edge of the product.

[0006] As a preferred fixture structure for improving paint burrs according to this utility model, the flow obstruction groove is an annular groove.

[0007] As a preferred fixture structure for improving paint burrs according to this utility model, the cross-sectional shape of the flow obstruction groove is arc-shaped, V-shaped, or rectangular.

[0008] As a preferred fixture structure for improving paint burrs according to this utility model, the depth of the flow-blocking groove is 0.5mm to 2mm.

[0009] As a preferred embodiment of the fixture structure for improving paint burrs according to this utility model, multiple evenly distributed reinforcing ribs are fixedly connected to both the left and right sides of the upper end face of the base, and the reinforcing ribs on the left and right sides are symmetrically arranged with the fixture body as the center.

[0010] As a preferred fixture structure for improving paint burrs according to this utility model, the bottom of the base is equipped with multiple support feet.

[0011] The beneficial effects of this utility model are:

[0012] A flow-blocking groove is opened on the upper surface of the base and the edge of the fixture body. When painting or electroplating is performed, the paint or plating solution flowing along the surface of the fixture will be effectively intercepted and contained in the groove. This effectively improves the burr defects generated at the edges of the product during the painting or electroplating process, significantly improves the appearance quality and yield of the product, and reduces the labor cost and material waste of subsequent repair and cleaning. At the same time, its structural design enhances the rigidity and stability of the fixture itself and extends its service life. Attached Figure Description

[0015] Figure 2 This is the overall main view structural diagram of this utility model.

[0016] The markings in the diagram are: 1. Base; 2. Fixture body; 3. Flow obstruction groove; 4. Reinforcing rib; 5. Support leg. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-2 A fixture structure for improving paint burrs includes a base 1, a fixture body 2 fixedly connected to the center of the upper end face of the base 1, and a flow-blocking groove 3 provided along the edge of the fixture body 2 on the upper end face of the base 1. The flow-blocking groove 3 is used to block and contain paint or plating liquid flowing towards the edge of the product.

[0019] In this embodiment: a flow-blocking groove 3 is opened on the upper surface of the base 1 and at the edge of the fixture body 2. When painting or electroplating is performed, the paint or plating liquid flowing along the surface of the fixture will be effectively intercepted by this flow-blocking groove 3 and contained in the groove, thereby fundamentally blocking its path to the edge of the product, avoiding improper accumulation of paint at the joint between the product and the fixture, and eliminating burr defects from the source. At the same time, multiple reinforcing ribs 4 symmetrically arranged on the base 1 enhance the overall structural stability and prevent deformation, while multiple support feet 5 installed at the bottom suspend the bottom of the fixture, preventing the accumulated contaminated liquid from back-contaminating the product and ensuring the cleanliness of the processing.

[0020] As a technical optimization of this utility model, the flow obstruction groove 3 is an annular groove.

[0021] In this embodiment, the flow-blocking groove 3 is an annular groove, forming a continuous and closed blocking ring, ensuring that no matter how the fixture is placed or from which direction the paint flows, it can be intercepted without any blind spots, providing all-round and uniform spill protection.

[0022] As a technical optimization of this utility model, the cross-sectional shape of the flow obstruction groove 3 is arc-shaped, V-shaped, or rectangular.

[0023] In this embodiment, the cross-sectional shape of the flow-blocking groove 3 is arc-shaped, V-shaped, or rectangular, providing a variety of options suitable for coatings of different viscosities and process requirements.

[0024] As a technical optimization of this utility model, the depth of the flow obstruction groove 3 is 0.5mm to 2mm.

[0025] In this embodiment, the depth of the flow-blocking groove 3 is 0.5mm to 2mm, which can effectively accumulate a certain amount of liquid to achieve the flow-blocking effect, without being too deep and weakening the structural strength of the fixture body 2. It ensures functionality while taking into account the mechanical strength and durability of the fixture.

[0026] As a technical optimization of this utility model, multiple evenly distributed reinforcing ribs 4 are fixedly connected to the left and right sides of the upper end face of the base 1, and the reinforcing ribs 4 on the left and right sides are symmetrically arranged with the fixture body 2 as the center.

[0027] In this embodiment, the raised rib-like structures significantly increase the surface area and rigidity of the base, effectively resisting deformation caused by thermal expansion and contraction or external forces, ensuring the long-term dimensional stability of the fixture, while the symmetrical arrangement ensures uniform stress distribution.

[0028] As a technical optimization of this utility model, the bottom of the base 1 is equipped with multiple support feet 5.

[0029] In this embodiment: the bottom of the base 1 is equipped with multiple support feet 5 to provide basic support, which facilitates the placement and positioning of the fixture body 2.

[0030] The working principle and usage process of this utility model are as follows: After the product to be processed is installed and fixed on the fixture body 2, painting or electroplating operations can be carried out. During the process, it is inevitable that excess paint or plating liquid will splash and accumulate on the surface of the fixture. Under the action of gravity and surface tension, these liquids will naturally flow to lower places. When they flow past the edge of the fixture body 2, they will be intercepted by the flow-blocking groove 3 pre-processed on the base 1. The liquid is captured and stored in the groove space of the flow-blocking groove 3, so that it cannot continue to flow to the critical joint between the product and the fixture body 2, thus fundamentally cutting off the source of material that forms burrs.

[0031] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
