Description

Technical Field

[0001] This utility model relates to the field of bearing housing clamping technology, and in particular to a quick clamping fixture for bearing housings. Background Technology

[0002] Bearing housings are generally manufactured using a casting process. First, a blank is cast using a mold, and then the blank is further machined using a machine tool to complete the manufacturing of the bearing housing. The inner hole and the inner mounting end face of the bearing housing are used for the installation and positioning of the bearing. When machining the bearing housing, clamping fixtures are required to clamp and install the bearing housing to ensure that it is placed stably before machining.

[0003] Existing bearing housing clamping fixtures have a relatively simple clamping structure, requiring manual rotation of the fixture to clamp the bearing housing one by one. This results in a slow clamping speed and failure to clamp quickly. Furthermore, when machining the bearing housing, the clamping fixture is held on the bearing housing, which affects the movement of the tool on the bearing housing and the machining process, and fails to provide space for the tool to move.

[0004] Therefore, a quick clamping fixture for bearing housings is provided. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a quick-clamping fixture for bearing housings. This fixture can drive the clamping bar to rotate and clamp the bearing housing, enabling rapid clamping of the bearing housing. It also provides space for the movement of the cutting tool, facilitating rapid machining of the bearing housing by the cutting tool.

[0010] Preferably, the top of the clamping platform has uniformly spaced placement slots, and support blocks are fixed on both sides of the top of the placement slots. The support blocks are made of aluminum blocks and are horizontally arranged. A first clearance slot is opened on one side of the support block, and the first clearance slot is an arc-shaped slot structure.

[0011] Preferably, the support block has a first insertion hole in the middle, the first insertion hole penetrates the surface of the clamping platform, and the support plate has a second insertion hole on its surface and located directly below the first insertion hole.

[0012] Preferably, the top of the rotary cylinder is connected to an extension end, the top of the extension end has a connecting hole, the top of the extension end slides through the second insertion hole and the first insertion hole, and its top protrudes from the top of the support block.

[0013] Preferably, the clamping strip has a second countersunk hole in the middle, and the clamping strip is abutted against the top of the protruding end. A second countersunk bolt passes through the inside of the second countersunk hole, and the bottom end of the second countersunk bolt is threaded into the connecting hole. The connecting hole is a threaded hole structure. The clamping strip is horizontally set, and its two ends are arc-shaped concave structures.
