Abstract
The utility model relates to a bench lathe locking device which comprises a spindle box, a spindle, a locking nut, a locking screw, a locking ring, a spring chuck seat, a spring chuck, a handle and a gear, wherein, one head of the locking nut is provided with an external gear, and the other end is provided with an internal thread; the external gear is engaged with a gear on a small shaft connected with the handle; the internal thread is screwed and connected with the locking screw; the production of the locking nut and the locking screw is simple, and the production cost of the entire device can be reduced.
Description
A kind of bench lathe locking device of the utility model relates to desk-top (instrument) lathe clamping work pieces.
It is to utilize three claws that overhang in the main shaft back to drive the collet clamping work pieces by the siphunculus that the circular cone dish spurs in the spindle hole backward that common desk-top lathe workpiece clamps, and that main shaft overhangs is long, volume is big.Obtain a kind of clamping device of the patent No. 972364646 of Chinese patent, this device is arranged in the main spindle box, adopts the turn of the dynamic and static end face rotating cam of helical angle that adapter sleeve is moved vertically, drives the collet clamping work pieces.Overcome the bulky shortcoming of bench lathe, still, the weak point of this clamping device is a rotary end surface cam production process complexity, the cost height.
The purpose of this utility model is to provide a kind of bench lathe locking device in order to reduce the manufacturing cost of bench lathe, to design.
The technical scheme that realizes the utility model purpose is as follows: it includes main shaft, main spindle box, locking nut, lock screw, clamp ring, handle, gear, spring clip headstock and collet, lock screw is fixedly connected on the main shaft cabinet wall and the main shaft casing is connected as a single entity, locking nut one end face and clamp ring movingly, its external gear is with the gears engaged of little axle one end, the fixedly connected spring clip headstock of mounting hole of main shaft is passed in clamp ring by bolt, the spring clip headstock collet that is threaded, its technical characterstic is that of locking nut is provided with external gear, one is provided with internal thread, internal thread screws with lock screw and is connected, and external gear connects with the gears engaged on the continuous little axle of handle.
The good effect that the utility model produces is, employing locking nut and lock screw screw the dynamic and static end face rotating cam of helical angle that is connected in the alternative existing clamping device and are connected with a joggle, the advantage that not only has a kind of clamping device that patents, and its cost is lower, helps enforcement production of the present utility model.
Below, in conjunction with the accompanying drawings with to the description of embodiment of the present utility model, detailed explanation technology contents of the present utility model.
Fig. 1 is the utility model topology view.
Fig. 2 is the locking nut topology view.
From Fig. 1, shown in Figure 2, lock screw 8 is fastenedly connected with the main shaft cabinet wall by bolt, it screws connection with locking nut 7, one end face of locking nut 7 by thrust bearing and clamp ring 2 movingly, holding pin in the clamp ring 2 is fixedly connected with the locating hole on the spring clip headstock 6 through the mounting hole of main shaft 9, one of spring clip headstock 6 is threaded with collet 10, locking nut 7 other ends are shaped on external gear 11 with meshing with little axle 1 gear that is connected 5, little axle 1 other end connects handle 3, turning handle 3 makes locking nut 7 axially being moved to the left along main shaft 9, drive collet 10 by thrust bearing roof pressure clamp ring 2 and move to left clamping work pieces vertically.Handle 3 resets, and locking nut 7 screws return with lock screw 8, and by the spring 4 roof pressures location that is arranged on main shaft 7 inner chambers one end.The thrust that lock screw 8 is subjected to is supported on the main shaft 9 by conical bearing by the thrust bearing of other end, keeps operating steadily of this device.Locking nut 7 internal threads of the present utility model are designed to double thread, and helical angle is set by 2 °～6 °, make helical pitch satisfy the needs of operation, can reach the requirement of self-locking again.
Claims (2)
1, a kind of bench lathe locking device, it includes main spindle box, main shaft, locking nut, lock screw, clamp ring, spring clip headstock, collet, handle and gear, it is characterized in that: (7) one of locking nuts have external gear (11), the other end is internal thread (12), internal thread screws with lock screw (6) and is connected, and the gear (5) on the little axle (1) that the same handle of external gear (11) (3) links to each other is connected with a joggle.
