Abstract
The utility model provides a finger-pressing chuck mechanism which is more suitable for high speed rotary movement, prevents incomplete positioning of an inflatable shaft and severe bouncing during high speed running. A retaining plate fixes the position of a chuck through a spring and a pressure bar, thereby ensuring operation safety of the chuck. The finger-pressing chuck mechanism comprises a chuck, a locating lever, a bearing pedestal, a feather key, a main shaft, a locating piece, the spring, the pressure bar, the retaining plate, a pressure plate and a positioning spring steel bead. Circular positioning and square transmission torque are employed, and an opening always faces upwards when the chuck deviates so as to prevent radial rotation of the chuck. The finger-pressing chuck mechanism is characterized in that the positioning spring steel bead and the retaining plate structure are provided on the chuck.
Description
Technical field
The utility model relates to a kind of finger-pressure type chuck mechanism, is particularly suitable for the high speed unwinding and rewinding mechanism of all kinds of wide cut strips.
Background technology
At present, package packing machine has been adopted the unwinding and rewinding structure, mainly be divided into and air-expanding shaft arranged and without the air-expanding shaft dual mode, there is the air-expanding shaft mode that multiple mounting modes is also arranged, but these all exist the location inaccurate when high-speed operation, and jerk value is large, poor stability, operation inconvenience and the high deficiency of requirement on machining accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of new chuck location and installation mode, can better adapt to high speed rotary motion.Chuck structure adopted square location air-expanding shaft, radial spring and steel ball positioning chuck position mostly in the past.This structure adopts circular location, square transmitting torque, and the retaining plate of employing finger-pressure type, and the air-expanding shaft location is more reliable, more accurate; Chuck location safety and reliability; Reduced simultaneously the requirement of working accuracy, and simple in structure, easy to operate.
For achieving the above object, described finger-pressure type chuck mechanism is comprised of chuck, radius stay, bearing seat, feather key, main shaft, locating piece, spring, depression bar, retaining plate, pressing plate, retainer spring steel ball; Adopt circle location air-expanding shaft, square transmitting torque; Opening radially can not rotate chuck all the time up when chuck left.Retainer spring steel ball and retaining plate structure are installed on the chuck.
Compared with prior art, this finger-pressure type chuck mechanism is easy to operate, and requirement on machining accuracy is low, and safety performance is good, can adapt to high speed rotary motion, and is simple and reliable for structure.

The specific embodiment
Please refer to shown in Figure 1ly, the utility model is comprised of chuck 1, radius stay 2, bearing seat 3, feather key 4, main shaft 5, locating piece 6, spring 7, depression bar 8, retaining plate 9, pressing plate 10, retainer spring steel ball 11.
In operating process, first air-expanding shaft is put into main shaft, promote chuck 1 away from bearing seat 3 till can not move, this moment, locating piece 6 and main shaft 5 were located air-expanding shaft 3 fully, retainer spring steel ball 11 snaps in the knock hole of main shaft, and chuck is positioned on the main shaft, then depresses depression bar 8, until retaining plate snaps in the back stop slot of main shaft, this is the process of dress air-expanding shaft.Otherwise, depress depression bar 8, pull out retaining plate 9, promote chuck 1 and move to bearing seat 3, make chuck 1 be stuck in radius stay 2 places, thereby chuck 1 can not be rotated again, this has just finished whole handling process.Fraud has been exempted from air-expanding shaft and can not be located fully and cause serious beating property when making high-speed operation in this process, retainer spring steel ball positioning chuck position, retaining plate is by spring and depression bar location, prevent that chuck chuck when high-speed operation from moving, the dual fixing safety that can better guarantee the chuck running.
