Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engineering machinery, and specifically relates to a combined V-block. Background Technology
[0002] V-blocks are support fixtures suitable for the visual and other inspections of shaft parts. Common V-blocks include fixed V-blocks and bearing-type V-blocks. However, these two types of V-blocks are two separate tooling systems. Sometimes, both types are needed simultaneously in the production process, which not only occupies extremely limited flat plate space but also causes inconvenience due to the similar size, leading to mistakes or frequent swapping. Therefore, there is an urgent need for a combined V-block that is simple in structure, occupies little space, has good versatility, and is easy to maintain. Summary of the Invention
[0003] To address the problems of large space occupation and inconvenience caused by the simultaneous use of fixed V-blocks and bearing V-blocks, which may lead to incorrect selection or repeated swapping, this invention provides a combined V-block consisting of a fixed V-block and a bearing V-block. This design does not increase the space occupied by the plate during inspection, and can simultaneously meet the inspection requirements of both non-rotating workpieces and parts that require rotation.
[0004] The specific technical solution adopted is as follows: a combined V-block, consisting of a fixed V-block and a bearing V-block. The upper part of the fixed V-block has two inclined surfaces distributed in a V-shape, and the bottom of the two inclined surfaces has a rectangular groove extending downwards. The bearing V-block consists of two side plates of the same shape and size, an intermediate plate disposed between the two side plates, and two bearings. The upper part of the side plates has a flat-bottomed V-groove, and bearing mounting holes are provided on both sides of the flat-bottomed V-groove. The bearings are installed between the bearing mounting holes of the two side plates, and the highest point of the bearings is higher than the highest point of the flat-bottomed V-groove. Multiple intermediate plate mounting holes are provided below the flat-bottomed V-groove. The intermediate plate is installed between the intermediate plate mounting holes of the two side plates, and the highest point of the intermediate plate is lower than the lowest point of the flat-bottomed V-groove. The distance between the two side plates is slightly greater than the thickness of the fixed V-block, and the intermediate plate is clamped between the two inclined surfaces of the fixed V-block.
[0005] Moreover, the middle plate is V-shaped with rounded corners at the bottom, the length of the top of the middle plate is greater than the distance between the two bearings, and the length of the bottom of the middle plate is greater than the width of the rectangular groove of the fixed V-block.
[0006] Furthermore, the bearing consists of a bearing core with threaded through holes, a plastic-coated bearing sleeved on the bearing core, and two bearing washers located at both ends of the bearing core. The diameter of the bearing washers is slightly larger than the diameter of the bearing mounting hole.
[0007] Compared with existing technologies, the beneficial effects of this technical solution are as follows:
[0008] (1) The combined V-block provided by this utility model has a fixed V-block and a bearing V-block. The two types of V-blocks can respectively meet the inspection requirements of non-rotating workpieces and parts that need to rotate.
[0009] (2) The middle plate is designed to avoid direct contact between the fixed V-block and the bearing V-block. Its bottom is rounded. The length of the top of the middle plate is greater than the distance between the two bearings, and the length of the bottom of the middle plate is greater than the width of the rectangular groove of the fixed V-block. This can prevent the workpieces from colliding with each other.
[0010] (3) The combined V-block structure provided by this utility model is simple, flexible and convenient to use, and the two types of V-blocks will not be confused when used. When combined together, the space occupied is significantly smaller than that occupied by the original independent V-blocks. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. However, the scope of the present invention is not limited to the following embodiments.
[0018] A composite V-block, consisting of a fixed V-block and a bearing-type V-block, such as... Figure 1 As shown, the fixed V-block 1 has two inclined surfaces 2 arranged in a V-shape at the top, and the bottom of the two inclined surfaces has a rectangular groove 3 extending downwards. The fixed V-block is a cuboid in shape, and the top and bottom of its inclined surfaces are parallel. Figure 2As shown, the bearing-type V-block consists of two side plates 4 of the same shape and size, a middle plate 5 located between the two side plates, and two bearings 6. The upper part of each side plate has a flat-bottomed V-groove 7, with rounded corners on both sides to make the bearing position more prominent. Bearing mounting holes are provided on both sides of the flat-bottomed V-groove, fixed with M5 screws 8. The bearings are installed between the bearing mounting holes of the two side plates, and the highest point of the bearing is higher than the highest point of the flat-bottomed V-groove, facilitating inspection of shaft parts. Three middle plate mounting holes are provided below the flat-bottomed V-groove, fixed with M8 screws 9. The middle plate is installed between the middle plate mounting holes of the two side plates, and the highest point of the middle plate is lower than the lowest point of the flat-bottomed V-groove, so it does not affect the inspection process or bearing rotation. The distance between the two side plates is slightly greater than the thickness of the fixed V-block, and the middle plate is secured between the two inclined surfaces of the fixed V-block. Figure 3 As shown, the bearing consists of a bearing core 10 with threaded through holes, a plastic-coated bearing 11 sleeved on the bearing core, and two bearing washers 12 located at both ends of the bearing core. The diameter of the bearing washers is slightly larger than the diameter of the bearing mounting holes. Furthermore, to avoid direct contact between the fixed V-block and the bearing-type V-block, the intermediate plate is V-shaped with rounded corners at the bottom. The length of the top of the intermediate plate is greater than the distance between the two bearings, and the length of the bottom of the intermediate plate is greater than the width of the rectangular groove of the fixed V-block.
[0019] A composite V-block formed by combining fixed V-blocks and bearing-type V-blocks, such as... Figure 4 As shown, the space occupied is significantly smaller than that of the original independent V-blocks. During use, since the bearing-type V-block is always on top and the fixed V-block is on the bottom, the appropriate V-block can be selected according to the inspection requirements, avoiding the inconvenience of picking the wrong one or having to switch them back and forth.
[0020] Compared with existing technologies, the beneficial effects of this technical solution are as follows:
[0021] (1) The combined V-block provided by this utility model has a fixed V-block and a bearing V-block. The two types of V-blocks can respectively meet the inspection requirements of non-rotating workpieces and parts that need to rotate.
[0022] (2) The middle plate is designed to avoid direct contact between the fixed V-block and the bearing V-block. Its bottom is rounded. The length of the top of the middle plate is greater than the distance between the two bearings, and the length of the bottom of the middle plate is greater than the width of the rectangular groove of the fixed V-block. This can prevent the workpieces from colliding with each other.
[0023] (3) The combined V-block structure provided by this utility model is simple, flexible and convenient to use, and the two types of V-blocks will not be confused when used. When combined together, the space occupied is significantly smaller than that occupied by the original independent V-blocks.
