When the push rod motor 127 is in operation, the push rod of the push rod motor 127 can do linear reciprocating motion, for example, when the push rod motor 127 rotates anticlockwise, the push rod of the push rod motor 127 extends, and when the push rod motor 127 rotates clockwise, the push rod of the push rod motor 127 retracts. The suction block 1231 can reciprocate linearly relative to the electromagnet 1232 under the driving of the push rod motor 127, so as to drive the pressing push rod 1252 to reciprocate linearly. For example, when the push rod of the push rod motor 127 is extended, the suction block 1231 is moved in a direction away from the electromagnet 1232, and when the push rod of the push rod motor 127 is retracted, the suction block 1231 is moved in a direction toward the electromagnet 1232. The push rod motor 127 may be a push rod motor commonly used in the market, and in this embodiment, the push rod motor 127 is preferably a dc motor type push rod motor.
In summary, the clamping device and the gear grinding machine provided by the embodiments of the present invention, compared with the prior art, the clamping device includes: inhale and press subassembly, push rod motor, adjusting part and compress tightly the subassembly. Wherein, the regulation subassembly includes: the device comprises a first adjusting rod, a second adjusting rod, a pressure spring and an adjusting hand wheel; the suction and compression assembly comprises: a suction block and an electromagnet; the compression assembly includes: the device comprises a pressing main shaft, a pressing block, a pressing push rod, a pressing spring and a spring positioning pin. The adjusting component is used for adjusting the thickness of the gear or the saw blade to be processed so as to adapt to the processing requirements of various sizes; the push rod motor is used for driving the compressing assembly to do reciprocating motion; the suction and compression assembly is used for pushing the compression assembly to move; the pressing component can do reciprocating motion under the drive of the push rod motor, so that a gear or a saw blade to be processed is clamped. Because the clamping device adopts the electromagnet and the push rod motor as a power source for pushing the compression assembly to do linear motion, the problems of poor stability and low machining precision of the oil pressure and pneumatic clamping device are solved, in addition, because the electromagnet has low energy consumption, the probability of failure is relatively low, the machining efficiency is improved, and the maintenance cost is reduced. In addition, the clamping device has no problems of oil pressure, oil leakage and liquid leakage of the pneumatic clamping device and large noise, is environment-friendly and sanitary, meets the national requirements on environment protection, and can better adapt to the demands of markets and clients. The clamping device further comprises: simple structure, easy maintenance, low requirement on maintenance personnel, strong applicability (not limited by air temperature and area), and the like.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
