Abstract
The utility model relates to a right angle grinder head, comprising a head casing, an output shaft arranged in the casing, a gear for driving the output shaft and a grinding wheel fixed on the end of the output shaft, wherein a locking pin push button is arranged on the head casing, a compression spring is arranged between the locking pin push button and the head casing, the locking pin push button is connected with the locking pin, and at least two stop hole are arranged on the gear along the periphery direction. The right angle grinder head is characterized in that: a cylinder sleeve is arranged out of the locking pin, the cylinder sleeve is tightly fitted on the head casing, and an O-seal ring is arranged between the locking pin and the cylinder sleeve. The right angle grinder head of the utility model can effectively avoid external foreign body intrusion, and prevents the lubricating oil from leaking, thereby enhancing bearing service life and the durability of the gear.
Description
Technical field
The utility model relates to a kind of electric tool, relates in particular to a kind of angle grinding machine head.
Background technology
Because the grinding wheel of angle grinding machine is very easy to wear, need often to change, when changing grinding wheel, output shaft to be maintained static earlier, just grinding wheel can be pulled down and installed.The grinding wheel of inefficiency, and replacing like this is difficulty relatively.Chinese patent, the patent No. " 200820050259.7 " specification discloses " working head of a kind of angle grinding machine ", the working head of this angle grinding machine has solved the problems referred to above, but the sealing between its latch and the head capsule is poor, be easy to cause the intrusion of foreign like this, lubricating oil is easily revealed, and it is low service life to greatly reduce bearing, and the gear durability is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of angle grinding machine head, and the grinding wheel of this head is changed fast convenient, and the good airproof performance of head, improves the service life of bearing and the durability of gear effectively.
The technical solution adopted in the utility model is:
A kind of angle grinding machine head, comprise head capsule, place output shaft in the head capsule, drive the gear of output shaft and be fixed on the grinding wheel of output shaft end, described head capsule is provided with the lock pin button, between this lock pin button and the head capsule compression spring is housed, described lock pin button is connected with lock pin, and described gear upper edge peripheral direction is provided with at least two position-arresting holes, and described lock pin is provided with cylinder sleeve outward, this cylinder sleeve fits snugly on the head capsule, is provided with " O " shape sealing ring between described lock pin and the cylinder sleeve.
Further, be provided with sealing ring between described cylinder sleeve and the head capsule.
The utility model has installed cylinder sleeve additional outside lock pin, this cylinder sleeve fits snugly on the head capsule, and is provided with " O " shape sealing ring between lock pin and the cylinder sleeve.This design has guaranteed no matter which kind of state lock pin is in, and is remaining between lock pin and the cylinder sleeve to seal.Can avoid the intrusion of foreign like this, lubricating oil is easily revealed, thereby has improved the service life of bearing and the durability of gear.
