Abstract
The utility model discloses a handwheel locking structure which comprises a handwheel seat, wherein the handwheel seat is fixedly provided with a handle and matched with a dial. The handwheel locking structure is characterized in that a step through hole is formed in the middle of the handwheel seat, a locking screw is installed on the large end of the step through hole, a screw rod is installed on the small end of the step through hole, and the end of the screw rod is matched with the handwheel seat through the locking screw; the locking screw comprises a threaded rod and a screw cap which are connected into a whole, a circular groove is formed in the connecting position of the threaded rod and the screw cap, and the threaded rod is provided with external threads; and adjusting holes and internal thread locking holes are distributed in the screw cap and positioned on a same circle at the edge of the screw cap outside the threaded rod. The handwheel locking structure has the advantages of reasonable structure design, good locking and positioning effect, and convenience for alignment and adjustment, the problems of easiness in looseness, damaged or falling threads, effects on feeding accuracy and work efficiency due to frequent replacement and the like which are caused after use for a long time are avoided, and operating requirements are satisfied.
Description
Technical field
The utility model relates to a kind of lathe wheel feed structure, relates in particular to a kind of hand wheel locking structure.
Background technology
The wheel feed structure mostly adopts screw that handwheel, screw mandrel and scale plate are fixed, locate, regulated in the lathe, existing screw all is comprised of nut and screw rod, and it is simple in structure, because the frequency of work, in the use procedure, existing hand wheel locking structure be inconvenient to regulate aligning, and locking positioning is poor when regulating, rear easily loosening, the thread of long-time use damages or comes off, affect the accuracy rate of feeding, need often to change, affect operating efficiency.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of hand wheel locking structure is provided, it is simple to have solved existing bolt structure, regulate and aim at inconvenience, locking 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 operating efficiency.
The utility model is achieved through the following technical solutions:
A kind of hand wheel locking structure, include the handwheel seat, be installed with handle on the described handwheel seat, cooperate on the described handwheel seat dial is installed, it is characterized in that: described handwheel seat middle part is provided with step through-hole, the large end of described step through-hole is equipped with lock-screw, described step through-hole small end is equipped with screw mandrel, described screw mandrel end cooperates with the handwheel seat by lock-screw, described lock-screw includes screw rod and the nut that connects as one, described screw rod and nut junction are provided with annular groove, described screw rod is provided with external screw thread, be distributed with adjustment hole and internal thread locking hole on the described nut, and adjustment hole and internal thread locking hole are positioned on the same circumference of nut edge in the screw rod outside.
Described nut is circular disk body.
Be evenly equipped with four adjustment holes on the described nut, with the same circumference of adjustment hole, and differ from the adjustment hole position and be provided with an internal thread locking hole on the described nut.
Its principle is: by the step through-hole that is provided with at the handwheel seat, made things convenient for the installation of lock-screw, adjust screw mandrel by the screw rod of lock-screw simultaneously, gap between dial and the handwheel, design by the adjustment hole on the nut and locking hole, 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, screw in lathe handwheel holding screw by locking hole simultaneously, increased the positioning and locking contact-making surface, the handwheel end face is carried out dieback, avoided long-time use loosening easily afterwards, thread damages or comes off, and affects the accuracy rate of feeding, need often to change, affect the problems such as operating efficiency
The utility model has the advantages that:
The utility model reasonable in design, locking 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 operating efficiency, satisfied instructions for use.
