Description

Technical Field

[0001] The utility model relates to the technical field of motor shell end surface processing, in particular to a clamp for processing the end surface of a water-cooled motor shell. Background Art

[0002] Mining motors are electric motors that convert electrical energy into mechanical energy and are suitable for the environmental conditions underground in coal mines and the working requirements of the driven equipment.

[0003] The surface temperature of mining motors will increase when they are working. In order to achieve the effect of rapid cooling, mining motors on the market now usually use air-cooled motors and water-cooled motors. In the prior art, when performing end surface processing on the motor shell of a water-cooled motor for mining, most of them directly clamp the motor shell on the three-jaw chuck of the machine tool. The motor shell of the water-cooled motor for mining has a large diameter. Clamping from the outside will make the equipment clamping chuck very large and occupy more space. In addition, the use of external clamping will also affect the processing of the end surface of the motor shell, making the end surface processing incomplete. Utility Model Content

The outer wall of the hollow shaft is provided with three groups of limiting grooves in a circular and equidistant manner. Support strips are hinged on the three groups of left hinged seats and the three groups of right hinged seats. Two groups of fixed seats are symmetrically fixed on the inner sides of the three groups of arc top plates. Each group of fixed seats is hinged to the inner end of each group of support strips, and two groups of support strips are passed through each group of limiting grooves. The front and rear ends of the support strips are in contact with the inner walls on the front and rear sides of the limiting grooves.

Two groups of supporting strips 9 are inserted into the positioning slots, and the front and rear ends of the supporting strips 9 are in contact with the inner walls of the front and rear sides of the limiting slots; when in use, the connecting shaft 1 is clamped on the three-jaw chuck on the machine tool to install the fixture. At first, the curved top plate 6 is in a retracted state, and then the water-cooled motor shell to be processed is put on the three groups of curved top plates 6, and the adjusting stud 3 drives the connecting plate 5 to move to the left by screwing the knob 4. When the connecting plate 5 moves to the left, the curved top plate 6 is pushed outward by the supporting strips 9, so that the curved top plate 6 tightens the water-cooled motor shell from the inside, thereby fixing the motor shell, and then the motor shell of the water-cooled motor can be processed on the end surface. By clamping the motor shell of the mining water-cooled motor inside, the space occupied during clamping can be effectively saved, and the processing of the end surface of the motor shell can be avoided, so that the processing of the end surface of the motor shell can be more comprehensive.

[0023] The outer wall of the knob 4 is provided with a plurality of groups of anti-skid convex patterns 14 in an annular and equidistant manner. The anti-skid convex patterns 14 can prevent the hand from slipping when the knob 4 is turned.

[0024] The utility model discloses a fixture for processing the end face of a water-cooled motor housing. The working principle is that when in use, a connecting shaft 1 is clamped on a three-jaw chuck on a machine tool to install the fixture. Initially, a curved top plate 6 is in a retracted state. Then, the water-cooled motor housing to be processed is sleeved on the three groups of curved top plates 6. By screwing a knob 4, an adjusting stud 3 drives a connecting plate 5 to move to the left. When the connecting plate 5 moves to the left, the curved top plate 6 is pushed to move outward through a supporting strip plate 9, so that the curved top plate 6 presses the water-cooled motor housing from the inside, thereby fixing the motor housing. Then, the end face of the motor housing of the water-cooled motor can be processed.
