The contrast of the device and current limiting device, have simple structure, can be fast spacing, can the auto -lock, convenient to use, maintenance be convenient, improved work efficiency, and has guaranteed part machining precision.
Description
Technical field
The utility model belongs to stopping means field, especially a kind of stopping means coordinated with drillman's station.
Background technology
Application number 201210316452.1 discloses a kind of stopping means, when solving testboard swing in prior art, the amplitude of oscillation easily occurs excessive, unsafe problem; This stopping means can make testboard carry out micro-swinging, makes test process safer.This stopping means is applied in drilling tool and there is following problem: complex structure, can not fast spacing, can not self-locking, problem that production cost is high.
Summary of the invention
The utility model provides a kind of stopping means, this apparatus structure is simple, can fast spacing, can self-locking, and easy to operate, be convenient to safeguard, improve operating efficiency.
In order to solve the problems of the technologies described above, technical solutions of the utility model are: a kind of stopping means, comprise handlebar, it is characterized in that: one end of handlebar is provided with the limited block be fixedly connected with, axis hole is provided with in limited block, the holder be fixedly connected with is provided with in axis hole, marble hole is provided with in holder, position-limited marble and pellet return spring is provided with in marble hole, position-limited marble passes through pellet return spring along axis hole axially-movable, holder is provided with the shaft hole with axis hole coaxial line, holder is fixedly connected with the rotating shaft on bearing by the shaft hole on it, bearing is distributed with ball groove relative on a side of position-limited marble, position-limited marble and ball groove spacing, locking coordinates.
Further limit technique scheme, described limited block is rectangle; Rectangular limited block, contact surface is larger, and stability is good, weares and teares little; Flute profile on limited block and Drilling machines bench matches, and ensure that the precision of processing parts.
Further limit technique scheme, described position-limited marble is steel ball shape; Because steel ball and bearing are point cantact, which decrease frictional force, be convenient to steel ball and move between ball groove.
Beneficial effect: the 1. holder in limited block is fixedly connected with the rotating shaft on bearing by the shaft hole on it, realizes handlebar and position-limited marble integrated rotating, simple to operate like this; 2. after limited block rotates to an angle, simultaneously steel ball moves in another ball groove in a ball groove, and by pellet return spring, steel ball is stuck in ball groove, thus limited block cannot move, and reaches the object of spacing, self-locking fast; 3. this device and existing stopping means contrast, have structure simple, can fast spacing, can self-locking, easy to use, easy to maintenance, improve operating efficiency, and ensure that part processing precision.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of stopping means, comprise handlebar 1, one end of handlebar 1 is provided with the rectangle limited block 2 be fixedly connected with by welding manner, axis hole 3 is provided with in rectangle limited block 2, the holder 4 be fixedly connected with by welding manner is provided with in axis hole 3 one end, marble hole is provided with in holder 4, position-limited marble 5 and pellet return spring 6 is provided with in marble hole, position-limited marble 5 passes through pellet return spring 6 along axis hole 3 axially-movable, holder 4 is provided with the shaft hole with axis hole 3 coaxial line, holder 4 is fixedly connected with the rotating shaft 8 on bearing 7 by the shaft hole on it, handlebar 1 and holder 4 is made to realize integrated rotating by rotating shaft 8, bearing 7 is distributed with two ball grooves 9 relative on a side of position-limited marble 5, position-limited marble 5 is spacing with ball groove 9, locking coordinates, realize carrying out locking after rectangle limited block 2 rotates to an angle, and rectangle limited block 2 coordinates with the bar-shaped trough in drillman's station is spacing.
Operation principle: as shown in Figure 3,1. the bearing in stopping means is fixed on U-type groove mouth 11 place on rotating disc 10 by welding or bolt connecting mode, rotating disc 10 can rotate in drillman's station 12, and rotating disc makes the limited block in stopping means corresponding with the bar-shaped trough 13 in drillman's station 12 after rotating to certain angle; 2. make limited block be positioned at bar-shaped trough 13 in drillman's station 12 by rotary handle bar, simultaneously, the position-limited marble being positioned at the first ball groove rotates to the second ball groove, achieve limited block to coordinate with the bar-shaped trough 13 in drillman's station 12 is spacing, shape and the bar-shaped trough of limited block adapt, and limited block to coordinate and pellet return spring carries out locking by position-limited marble and the second ball groove are spacing; 3. reversely rotating handlebar makes the bar-shaped trough in limited block and drillman's station depart from, and meanwhile, be positioned at the position-limited marble rotation of the second ball groove to the first ball groove, limited block to coordinate and pellet return spring carries out locking by position-limited marble and the first ball groove are spacing.
Do not elaborate in this description part, is technology well known in the art.
