Abstract
The utility model discloses a lathe hand wheel locking screw. The lathe hand wheel locking screw comprises a screw rod and a nut, and the screw rod and the nut are connected into a whole. The lathe hand wheel locking screw is characterized in that a ring-shaped groove is arranged in a connection section of the screw rod and the nut, outer screw threads are arranged on the screw rod, an inner screw thread locking through hole is arranged in the middle part of the nut, the inner screw thread locking through hole penetrates through the middle part of the screw rod, and the nut outside the inner screw thread locking through hole is provided with regulating holes. The lathe hand wheel locking screw has the advantages that structural design is reasonable, effects of locking and locating are good, and alignment adjustment is convenient. Problems that the lathe hand wheel locking screw is easy to loosen and thread teeth are damaged or fall off after a long time of usage, accuracy rate of feeding is affected, frequent replacement is needed, working efficiency is affected, and the like are solved, and use demands are satisfied.
Description
Technical field
The utility model relates to a kind of screw, relates in particular to a kind of lathe wheel screw.
Background technique
Screw is the threaded fastener with various structure shape heads, be used for the fixing of various connections, most of screws all are comprised of nut and screw rod, it is simple in structure, be applied between handwheel, screw mandrel and the scale plate of lathe feeding fixedly the time, because the frequency of work, existing lathe wheel screw is when regulating, be inconvenient to regulate aligning, and locking and positioning is poor, and rear easily loosening, the thread of long-time use damages or comes off, and affects the accuracy rate of feeding, need often to change, affect working efficiency.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of lathe wheel screw is provided, it is simple to have solved existing bolt structure, regulate and aim at inconvenience, locking and positioning is poor, and rear easily loosening, the thread of long-time use damages or comes off, and affects the accuracy rate of feeding, need often to change, affect the problems such as working efficiency.
The utility model is achieved through the following technical solutions:
A kind of lathe wheel screw, include the screw rod and the nut that connect as one, it is characterized in that: described screw rod and nut joint are provided with annular groove, described screw rod is provided with outside thread, described nut middle part is provided with the internal thread locking through hole, described internal thread locking through hole passes the screw rod middle part, is distributed with adjustment hole on the nut in the described internal thread locking through hole outside.
Described nut is circular disk body, and is evenly equipped with four adjustment holes on the nut.
Its principle is: by the structural design of screw rod self, adjust the gap between screw mandrel, dial and the handwheel, design by the adjustment hole on the nut, regulate on time at needs, inserting the spanner that cooperates with the hole in the adjustment hole can realize regulating, easy to adjust, time saving and energy saving, by screwing in lathe handwheel Cock screw in the internal thread locking through hole, increased the positioning and locking surface of contact simultaneously, the handwheel end face has been carried out dieback, avoided long-time use afterwards easily loosening, thread damage or come off, affect the accuracy rate of feeding, need often to change, affect the problems such as working efficiency
The utility model has the advantages that:
The utility model reasonable in design, locking and positioning is effective, aim at easy to adjust, avoided long-time use afterwards easily loosening, thread damage or come off, affect the accuracy rate of feeding, need often replacing, affect the problems such as working efficiency, satisfied usage requirement.
