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
The present invention relates to the tommyhead bolt field, particularly a kind of quick change T shape screw seat.
Background technology
In large-scale boring, mill, on the lathe such as vertical lathe, the facilities such as general supporting ground black iron, workbench are used for clamping workpiece and use, ground black iron, workbench are provided with T-shaped groove, the T-shaped slot length scope of big-and-middle-sized workbench is the 5-20m left and right, existing general T-shaped slot bolt can only draw inward from the termination of groove, until the position that needs, because T-shaped groove back warp often has iron filings, this has increased difficulty to drawing bolt, affects operator's operating efficiency.For the workpiece of differing heights, prepare the tommyhead bolt of different length in addition, interchangeability is poor each other, and in order to satisfy a large amount of tommyhead bolts of need of production configuration, cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of quick change T shape screw seat, overcome the deficiencies in the prior art, can insert in any position of T-shaped groove, 90-degree rotation can pin, and is convenient and time-saving, and the raising machine adds efficient.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of quick change T shape screw seat, comprise a head, connecting rod and screw shell, the seat head is that its width of wicker leaf shape is less than T-shaped channel opening width, the seat head is connected to form integral structure with connecting rod and screw shell successively along central axis, screw shell is provided with internal thread, and described seat head is the dextrorotation wicker leaf shape.
The sharp edge angle α of described seat head is 60-70 °, and root face chamfering radius R is 15-20mm.
Compared with prior art, the invention has the beneficial effects as follows: this device can be equipped with all lengths studs, and interchangeability is strong, and is simple in structure, easy for installation, with low cost, can significantly improve operating efficiency, reduces lathe non-cutting time.
Description of drawings
Fig. 1 is embodiment of the present invention structural representation.
Fig. 2 is the upward view of Fig. 1.
In figure: 1-seat head 2-connecting rod 3-screw shell
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
See Fig. 1, it is a kind of quick change T of the present invention shape screw seat example structure schematic diagram, comprise a head 1, connecting rod 2 and screw shell 3, seat head 1 is that its width of dextrorotation wicker leaf shape is less than T-shaped channel opening width, seat head 1 is connected with screw shell 3 with connecting rod 2 successively along central axis, screw shell 3 is provided with internal thread, can select M30, M36 equal-specification according to lathe needs internal thread.
The sharp edge angle α of seat head 1 is 60-70 °, and root face chamfering radius R is 15-20mm.
When workpiece is put into clamping location, workbench center, near the cleaning workpiece T-shaped groove is a bit of, as long as the seat head can go down, then 90-degree rotation in the T-shaped groove of the vertical insertion of this device can be pinned, then connect the studs that needs length on screw shell, because the seat head is the dextrorotation wicker leaf shape, so during fastening studs, the seat headstock can and then not rotate, and it is time saving and energy saving that clamping workpiece just becomes.
Claims (2)
