Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a fixing device for mechanical processing. Background Art

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. During processing, the workpiece needs to be fixed, so a special fixture or structure is used to position and fix the workpiece. Some workpieces with regular shapes and horizontal bottoms can be placed directly on the table for support, but some products with inclined tops and horizontal processing on the upper part need to make special support bases for support at the bottom. However, due to the wide variety of products, many types of bases need to be used, which makes it inconvenient to use and the cost is high. Utility Model Content

[0006] Preferably, an adapter is provided at the end of the threaded rod, and the adapter is rotatably mounted on the threaded rod. The side of the side fixing plate close to the adapter is hinged to the adapter, so that the direction of the side fixing plate can be changed when the workpiece is clamped, and when the side wall of the workpiece has an inclined portion, it can also adapt itself through the rotation of the side fixing plate and the adapter.

[0007] Preferably, support blocks are provided at the tops of both ends of the longitudinal support rod, and the support blocks are rotatably connected to the longitudinal support rod through a ball head connector, thereby changing the surface contact of the longitudinal support rod on the workpiece into point contact, so that stable support can be provided even when the bottom of the workpiece is uneven.

Therefore, when positioning the workpiece, the spirit level can be adjusted to a suitable height, and then the height support rod is slid to move the spirit level to the top surface of the workpiece, so that the workpiece can be leveled and then the workpiece can be fixed to ensure that the top surface of the workpiece is level, so as to facilitate processing of its horizontal surface.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The utility model installs a transverse support rod on a support seat and installs longitudinal support rods at both ends of the transverse support rod. When the workpiece is tilted or the irregular end faces downward, the bottom end of the workpiece can be made to contact the two groups of longitudinal support rods. The two groups of longitudinal support rods can automatically adapt to the inclined bottom surface of the workpiece.
