Description
Technical field
The utility model belongs to angle grinding machine auxiliary equipment technical field, relates to a kind of locking mechanism, particularly can realize the angle grinding machine locking mechanism of quick handling.
Background technology
At present angle grinding machine locking mechanism used mainly: lock shaft and locking button are common interference fit, and lock shaft is circular shaft, there is no locating piece, the hole of head capsule is circular hole, when installation first lock shaft from head capsule inside through head capsule outside, then put locking spring, be pressed into locking button.The shortcoming of this structure is: 1. this interference fit, if the magnitude of interference is little, locking button is easily thrown off, dangerous in lower easy appearances that run up of angle grinding machine, if the magnitude of interference is large, locks button perishable; 2. assembling inconvenience; 3. dismounting inconvenience.
Summary of the invention
The utility model is in order to overcome the defect of prior art, design angle grinding machine locking mechanism, can effectively improve efficiency of assembling, make repair demolition rapid and convenient more, load and unload more laborsaving, improve safety and reliability when angle grinding machine uses simultaneously, and reduced the spoilage of locking button in assembling process, saved production cost.
The concrete technical scheme that the utility model adopts is: angle grinding machine locking mechanism, comprise lock shaft, locking spring, locking button, be arranged on the through hole on head capsule, locking spring break-through is on lock shaft, one end of lock shaft forms locking with locking button and coordinates, key is: on the outer wall of the described lock shaft other end, be symmetrically arranged with locating piece, in through hole, offer the yi word pattern groove matching with locating piece, on the inwall of head capsule, offer the deep gouge arranged in a crossed manner with groove, lock shaft forms locking by the cooperation of locating piece and deep gouge with head capsule and coordinates.
The beneficial effects of the utility model are: on lock shaft, set up locating piece, in the through hole of head capsule, offer groove, and offer deep gouge on the inwall of head capsule, make lock shaft and head capsule form rotational lock and coordinate, compared with coordinating with existing interference locking, simple in structure, easy to loading and unloading, more laborsaving, effectively improve efficiency of assembling, make repair demolition rapid and convenient more, reduced the spoilage of locking button in assembling process simultaneously, saved production cost.Through hole is shoulder hole, and lock shaft coordinates with the aperture of through hole, and one end of locking spring contacts with the step of shoulder hole, the other end contacts with locking button, increase the recovery elastic force of locking spring, lock shaft can be entered in deep gouge rapidly, time saving and energy saving when installation.Lock shaft forms locking by the cooperation of limited impression and spacing preiection with locking button and coordinates, when installation, lock shaft and locking button can be press-fited to locking by less pressure, improve installation effectiveness, can effectively prevent lock shaft and locking button generation axial displacement simultaneously, while effectively avoiding angle grinding machine to run up, lock the generation of button dropping situations, improved safety and reliability when angle grinding machine uses.The front end of limit shaft is provided with chamfering structure, when installation, can reduce the frictional force between limit shaft and locking hole, more laborsaving while making to install.

Detailed description of the invention
Angle grinding machine locking mechanism, comprise lock shaft 2, locking spring 3, locking button 4, be arranged on the through hole 5 on head capsule 1, locking spring 3 break-through are on lock shaft 2, one end of lock shaft 2 forms locking with locking button 4 and coordinates, key is: on the outer wall of described lock shaft 2 other ends, be symmetrically arranged with locating piece 6, in through hole 5, offer the yi word pattern groove 7 matching with locating piece 6, on the inwall of head capsule 1, offer the deep gouge 8 arranged in a crossed manner with groove 7, lock shaft 2 forms locking by the cooperation of locating piece 6 and deep gouge 8 with head capsule 1 and coordinates.
Described deep gouge 8 and groove 7 square crossing settings.
Described through hole 5 is shoulder hole, and lock shaft 2 coordinates with the aperture of through hole 5, and one end of locking spring 3 contacts with the step of shoulder hole, and the other end contacts with locking button 4.
On described locking button 4, offer locking hole 9, one end of lock shaft 2 is provided with the limit shaft 10 matching with locking hole 9, on limit shaft 10, offer limited impression 11, in locking hole 9, be provided with the spacing preiection 12 matching with limited impression 11, lock shaft 2 forms locking by the cooperation of limited impression 11 and spacing preiection 12 with locking button 4 and coordinates.
The front end of described limit shaft 10 is provided with chamfering structure 13.
The utility model is in the specific implementation: when installation, first locking spring 3 is set on lock shaft 2, then the limit shaft 10 of lock shaft 2 one end is inserted in the locking hole 9 on locking button 4, promoting the spacing preiection 12 that lock shaft 2 makes to lock on button 4 just in time enters in limited impression 11 again, thereby locking button 4 and lock shaft 2 are press-fited to locking, then lock shaft 2 is inserted in the through hole 5 on head capsule 1, promote locking button 4, make the locating piece 6 on lock shaft 2 enter head capsule 1 inside along the groove 7 of offering in through hole 5, then half-twist, unclamp, under the elastic force effect of locking spring 3, locking button 4 can drive lock shaft 2 outwards to move, locating piece 6 on lock shaft 2 is entered in the deep gouge 8 of head capsule 1, so far complete the installation process of lock shaft 2.
