Embodiment Construction

[0011] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0012] See figure 1 , is a structural schematic diagram of an embodiment of a quick-change T-shaped screw seat of the present invention, including a seat head 1, a connecting rod 2 and a threaded sleeve 3, and the seat head 1 is in the shape of a right-handed willow leaf, and its width is smaller than the width of the opening of the T-shaped slot , The seat head 1 is sequentially connected with the connecting rod 2 and the threaded sleeve 3 along the central axis, and the threaded sleeve 3 is provided with internal threads. According to the requirements of the machine tool, the internal threads can be selected from M30, M36 and other specifications.

[0013] The angle α of the sharp edge of the seat head 1 is 60-70°, and the rounding radius R of the blunt edge is 15-20mm.

[0014] When the workpiece is placed in the center of the workbench for cl...

Abstract

The invention relates to the field of T-shaped bolts, in particular to a quick-changing T-shaped screw seat. The quick-changing T-shaped screw seat is characterized by comprising a seat head, a connecting rod and a threaded sleeve. The seat head is in a right-handed rotation salix leaf shape. The width of the seat head is smaller than the width of an opening of a T-shaped groove. The seat head is sequentially connected with the connecting rod and the threaded sleeve along a central shaft to form an integrated structure. Inner threads are arranged in the threaded sleeve. An included angle alpha formed by sharp edges of the seat head is 60-70 degrees. The radius R of a fillet of a blunt edge is 15-20mm. Compared with the prior art, the quick-changing T-shaped screw seat has the advantages of being capable of assembled with double-head bolts with various lengths, strong in interchange performance, simple in structure, convenient to install, low in cost, and capable of remarkably improving work efficiency and reducing auxiliary time of a lathe.

Description

technical field [0001] The invention relates to the field of T-shaped bolts, in particular to a quick-change T-shaped screw seat. Background technique [0002] On large-scale boring, milling, vertical lathes and other machine tools, it is generally equipped with facilities such as horizontal irons and workbenches for clamping workpieces. There are T-shaped slots on the horizontal irons and workbenches, and the length range of T-shaped grooves for large and medium-sized workbenches The length is about 5-20m. The current general-purpose T-slot bolts can only be guided from the end of the slot to the required position. Since there are often iron filings in the T-slot, this makes it difficult to guide the bolts and affects the operator. work efficiency. In addition, for workpieces of different heights, T-shaped bolts of different lengths must be prepared, which are poorly interchangeable. In order to meet production needs, a large number of T-shaped bolts must be configured, re...
