Abstract
The utility model relates to a pneumatic tool, the grinding wheel of which can be conveniently replaced. The pneumatic tool comprises a gear, a main shaft, an upper keep plate, a grinding wheel, a lower keep plate, a bearing and a shell, wherein, the gear is fixed on the main shaft which is mounted on the shell via the bearing, the upper keep plate, the grinding wheel and the lower keep plate are orderly fixed on the lower end of the main shaft, a braking button is arranged on one side of the shell, a pressure spring is nested on the braking button, a positioning pin is arranged on the lower side of the braking button, the upper end of the positioning pin is extended into a notch under the braking button, and a plurality of positioning holes are arranged on the position of the lateral surface of the gear, which corresponds to the braking button. The grinding wheel of the pneumatic tool can be dismounted only by a single wrench, so the replacement of the grinding wheel is simple and convenient and saves time and labor, thus increasing working efficiency.
Description
Technical field
The utility model belongs to the pneumatic tool field, specifically is a kind of pneumatic tool of being convenient to change emery wheel.
Background technology
Existing pneumatic tool needs to use two spanners to come the dismounting emery wheel when changing emery wheel usually, dismounting when (installations) first jaw with a spanner snap in the flat groove notch on the main shaft, main shaft is fixed, dismantled the pressing plate of fixed emery wheel again with an other spanner, thereby change emery wheel.Because the high and low position of two spanners is very near, and the both hands that the operator grips spanner collide with together easily, not only the dismounting emery wheel is very hard, and both hands are also injured easily during dismounting.Obviously, it is both inconvenient, also dangerous that existing pneumatic tool is changed emery wheel, influences operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of pneumatic tool of being convenient to change emery wheel is provided, and makes air tool replacing emery wheel process become convenient, laborsaving, thereby increases work efficiency.
The purpose of this utility model realizes as follows: a kind of pneumatic tool of being convenient to change emery wheel, comprise gear, main shaft, top board, emery wheel, lower platen, bearing, casing, its middle gear is fixed on the main shaft, main shaft is contained on the casing by bearing, top board, emery wheel, lower platen is fixed on the main shaft lower end successively, be characterized in that casing one side is provided with locking key, be with stage clip on the locking key, the locking key below is provided with alignment pin, the alignment pin upper end is stretched in the notch of locking key bottom, and gear side and locking key have some locating holes on the corresponding position.
Owing on casing, be provided with locking key, when needs are changed emery wheel, only need locking key is pressed in the locating hole that makes its insertion gear side, end, gear just is fixed, main shaft and be contained in upper and lower pressing plate on the main shaft and emery wheel also is fixed and can not rotates, just can pull down lower platen and change emery wheel with spanner this moment.After changing emery wheel, as long as the take-off the brake button, locking key withdraws from the locating hole of gear under the effect of stage clip, and gear and main shaft etc. just can normal rotation.Because the utility model only needs single the spanner just can the dismounting emery wheel when changing emery wheel, make change the emery wheel process become simply, make things convenient for, time saving and energy saving, so operating efficiency is greatly improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of gear 2 of the present utility model.
Fig. 3 is the structural representation of locking key 1 of the present utility model.
Among the figure: 1 expression locking key; 2 expression gears; 3 expression main shafts; 4 expression top boards; 5 expression emery wheels; 6 expression lower platens; 7 expression bearings; 8 expression locating holes; 9 expression alignment pins; 10 expression stage clips; 11 expression woodruff keies; 12 expression casings.
The specific embodiment
The utility model will be further described below with reference to accompanying drawing and by embodiment.
With reference to Fig. 1～Fig. 3, this pneumatic tool of being convenient to change emery wheel comprises gear 2, main shaft 3, top board 4, emery wheel 5, lower platen 6, bearing 7, casing 12, its middle gear 2 is fixed on the main shaft 3 by woodruff key 11, main shaft 3 is installed on the casing 12 by bearing 7, top board 4, emery wheel 5, lower platen 6 is fixed on main shaft 3 lower ends successively from top to bottom, casing 12 1 sides are provided with locking key 1, be with stage clip 10 on the locking key 1, there is an alignment pin 9 locking key 1 below, alignment pin 9 upper ends are stretched in the notch of locking key 1 bottom, have some locating holes 8 on gear 2 sides and the locking key 1 corresponding position.When this pneumatic tool need be changed emery wheel, as long as long as locking key 1 is pressed, the front end of locking key 1 is inserted in the locating hole 8 of gear 2 sides, gear 2 can be fixed, the pressing plate of main shaft 3 and lower end thereof, emery wheel etc. all are fixed simultaneously, only need this moment to use single spanner lower platen 6 can be pulled down, change emery wheel.Because the process of above-mentioned replacing emery wheel is comparatively simple and convenient, time saving and energy saving, required instrument is also less, therefore operating efficiency is greatly improved.
