Description

Technical Field

[0001] This utility model relates to the field of new energy gearbox processing technology, specifically a new energy gearbox housing processing fixture. Background Technology

[0002] In the manufacturing process of new energy vehicle transmissions, the machining accuracy of the transmission housing is crucial to the overall performance of the transmission, and machining fixtures are key tooling to ensure the machining accuracy of the housing. Existing machining fixtures for new energy vehicle transmission housings still have the following problems in use: Firstly, the fixture's fastening structure lacks flexibility, making it difficult to adapt to different specifications (such as size and shape) of transmission housings, resulting in significant limitations and poor versatility. Secondly, the fixture's load-bearing structure lacks effective anti-slip and cushioning designs, making it prone to displacement when the housing is placed, and the hard contact between the housing and the fixture during machining can easily cause wear on the housing surface, affecting product quality. Furthermore, the locking effect of the fastening components in traditional fixtures is poor, and the housing is prone to loosening due to vibration and other factors during machining, thus affecting machining accuracy. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a processing fixture for new energy gearbox housings. By setting up flexibly adjustable fastening components and anti-slip buffer bearing components, it solves the problems of poor fastening flexibility, insufficient versatility, poor load-bearing stability, and easy damage to the housing of existing fixtures.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a new energy gearbox housing processing fixture, including a bearing component, wherein multiple fastening components are configured on the bearing component.

[0007] The support assembly includes a support platform. Each of the four corners of the top of the support platform has a first slot, which is an oblong slot, facilitating the sliding table to slide flexibly along the horizontal direction of the support platform to adjust its position. Multiple anti-slip strips, made of rubber and bonded to the upper surface of the support platform, are evenly spaced from front to back on the upper surface of the support platform. These strips increase the friction between the gearbox housing and the support platform, improving the stability of the housing, and also provide cushioning protection, preventing wear on the housing surface due to hard contact. A fixed base is fixedly connected to each end of the support platform. Each fixed base is equipped with a lifting lug, which is U-shaped and has an anti-rust coating on its outer surface. This facilitates the lifting and transfer of the entire fixture, and the anti-rust coating also extends the service life of the lifting lug.

[0008] The fastening assembly includes a slide table slidably connected to the top of a support platform and located at the opening of a first slot. A first fastening bolt is fixedly connected to the bottom of the slide table, passing through the first slot on its corresponding side. Tightening the first fastening bolt locks the slide table in its position within the first slot. A sliding sleeve is fixedly connected to the top of the slide table, and a second slot, which is oblong, is provided on the side of the sliding sleeve to guide the up-and-down sliding of the slide rod and facilitate locking the height position. A slide rod is slidably connected inside the sliding sleeve, and a second fastening bolt is fixedly connected to the side of the slide rod. The second fastening bolt passes through the second slot on its corresponding side. Tightening the second fastening bolt locks the height position of the slide rod within the slide sleeve. A third fastening bolt is fixedly connected to the top of the slide rod. A downward fixing strip is provided on the slide rod. The downward fixing strip has an adapter hole for the third fastening bolt to pass through and assemble. The downward fixing strip can be assembled onto the slide rod through the third fastening bolt. Multiple anti-slip toothed grooves are equidistantly provided at the bottom of the downward fixing strip. The teeth of the anti-slip toothed grooves are triangular, which can enhance the engagement between the downward fixing strip and the gearbox housing and improve the fastening effect.

[0009] As a further improvement of this utility model: the first fastening bolt, the second fastening bolt and the third fastening bolt are all hand-tightening bolts, and the outer surface of their nuts is covered with anti-slip rubber sleeves, which makes it convenient for operators to manually tighten or loosen them. The anti-slip rubber sleeves increase the grip friction during operation and facilitate quick adjustment.

[0010] As a further improvement of this utility model, the pressing and fixing strip is made of metal. The metal material ensures the structural strength of the pressing and fixing strip, making it less prone to deformation during the fastening process of the gearbox housing, thus ensuring the reliability of the fastening.

[0011] As a further improvement of this utility model: the support platform is made of cast iron, and the outer surface of the support platform is coated with a wear-resistant coating. The cast iron material has good load-bearing performance and can stably support the gearbox housing; the wear-resistant coating extends the service life of the support platform and makes it more resistant to wear during processing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a slide table that can slide along the first strip groove, a slide rod that can slide along the second strip groove inside the slide sleeve, and a pressing and fixing strip that can be assembled by the third fastening bolt, enables the fastening components to be flexibly adjusted in the horizontal and vertical directions, and can also be adapted to pressing and fixing strips of different lengths, thereby adapting to the fastening requirements of new energy gearbox housings of different specifications, and greatly improving the versatility and adjustment flexibility of the fixture.

[0014] 2. This utility model increases the friction of the gearbox housing when it is placed by using rubber anti-slip strips on the upper surface of the support platform, which effectively improves the load-bearing stability. At the same time, the triangular anti-slip toothed grooves at the bottom of the pressing and fixing strip enhance the clamping and fastening effect on the housing, which can effectively prevent the housing from shifting during processing and ensure processing accuracy. In addition, the rubber anti-slip strips can also provide cushioning protection for the housing and reduce surface wear. Attached Figure Description
