Therefore, it is troublesome for the staff with more experience to judge when the power source is turned off.
SUMMERY OF THE UTILITY MODEL
Not enough to exist among the prior art, the utility model provides a motor base positioning fixture to thereby solve the time that the driving piece was closed to difficult control and lead to pressing from both sides tight not good problem of effect.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the motor base positioning clamp comprises a positioning seat, and a clamping piece for clamping the motor base is arranged on the positioning seat; the clamping pieces are arranged along the circumferential direction of the positioning seat, each clamping piece comprises a piston barrel which is transversely connected to the positioning seat in a sliding manner, a piston is transversely connected in the piston barrel in a sliding manner, a spring is fixed between the piston and the piston barrel, the end face of the piston barrel, which is far away from one end of the piston, is fixed and communicated with a buffering air bag, and a pressure limiting valve is installed on the buffering air bag; the piston barrel is arranged on the piston, the driving piece is used for driving the piston and the piston barrel to transversely slide, the pressure switch is electrically connected with the driving piece and used for closing the driving piece, and the pressure switch is arranged on one side of the piston close to the bottom surface of the piston barrel or on the bottom surface of the piston barrel.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. after piston barrel motion and motor base offset, the piston still can continue to slide in the piston barrel by the driving piece drive, and then makes the spring shrink, and gives the reverse effort that recovers of piston barrel behind the spring shrink for the piston barrel is inseparabler to offset on motor base, and it is better to press from both sides tight effect.
2. Compare and set up between two splint and two splint installation spring and then utilize the reaction force of spring to press from both sides tight motor base, piston and piston bucket can carry on spacingly mutually in this scheme, because spring coupling is not firm, can avoid the piston bucket to take place the skew after supporting tight motor base.
3. Gas in the piston barrel is discharged into the buffering air bag, the buffering air bag is directly contacted with the motor base, the air bag has flexibility, the damage to the motor base caused by overlarge rigid extrusion pressure can be avoided, the pressure limiting valve is arranged on the buffering air bag, when certain pressure is reached in the buffering air bag, the gas can be discharged through the pressure limiting valve, and the problem that the clamping effect is poor due to overlarge expansion of the buffering air bag is avoided.
4. Set up pressure switch, at the in-process that piston and piston barrel bottom surface are close to each other, pressure switch receives and closes the driving piece after the extrusion, can control the driving piece closing time for it is better to press from both sides tight effect.

In the figure: positioning seat 1, output shaft 2, piston bucket 3, piston 4, spring 5, buffering gasbag 6, motor base 7.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, and specific embodiments will be given.
As shown in figure 1, the motor base positioning fixture comprises a positioning seat 1, wherein a clamping piece for clamping a motor base 7 is installed on the positioning seat 1. The clamping piece sets up a plurality ofly along 1 circumference of positioning seat, and the clamping piece includes piston barrel 3 of horizontal sliding connection on positioning seat 1, and 3 longitudinal sections of piston barrel are the rectangle, are equipped with on the positioning seat 1 to supply 3 gliding slide rails of piston barrel, and 3 lower extremes of piston barrel rotate and are connected with the pulley, and pulley roll connection is in the slide rail.
Piston 4 is connected with in the piston bucket 3 horizontal sliding, is fixed with spring 5 between piston 4 and the piston bucket 3, and spring 5 can set up a plurality ofly and along 4 circumference equipartitions of piston to make spring 5's effort distribute more evenly. An air inlet hole is formed in the side wall of the piston barrel 3, an air inlet check valve is installed in the air inlet hole, and when the pressure in the piston barrel 3 is reduced, outside air can enter the piston barrel 3 through the air inlet check valve. The end surface of the piston barrel 3 is fixed and communicated with a buffering air bag 6, and a pressure limiting valve is arranged on the buffering air bag 6. In the embodiment, taking the motor base 7 as a circle as an example, three clamping pieces are arranged, the end surface of the piston barrel 3 is arc-shaped, and the buffering air bag 6 is also arc-shaped; if motor base 7 is the rectangle, then the clamping piece can set up two or four, the terminal surface of piston bucket 3 set up the level can, can set up according to the shape of the motor base 7 that needs processed in the actual conditions.
A driving piece for driving the piston 4 and the piston barrel 3 to transversely slide is fixed on the positioning seat 1, the driving piece adopts a cylinder, and an output shaft 2 of the cylinder is fixed with the piston 4. In this embodiment, one side of the piston 4 close to the bottom surface of the piston barrel 3 is fixed with a pressure switch which is electrically connected with the cylinder and used for closing the cylinder, and according to actual conditions, the pressure switch can also be installed on the bottom surface of the piston barrel 3.
During the specific use, place motor base 7 on positioning seat 1 for motor base 7 is located between a plurality of clamping pieces, starts the cylinder, and the cylinder drives piston 4, piston bucket 3 and slides to being close to motor base 7 direction together, and piston bucket 3 and positioning seat 1 pass through the pulley connection, are rolling friction between piston bucket 3 and the positioning seat 1 promptly, and it is littleer to compare sliding friction's friction, the slip of being convenient for. When buffering gasbag 6 and motor base 7 offset, piston barrel 3 is difficult to continue to slide, the cylinder continues to drive piston 4 and slides, spring 5 compresses, the space in the piston barrel 3 reduces, gas discharges to buffering gasbag 6 in, buffering gasbag 6 inflation probably leads to piston barrel 3 to have certain back-off, but spring 5 is in compression state all the time, and piston 4 reduces apart from 3 bottom surfaces of piston barrel apart from the interval gradually, when pressure switch on the piston 4 and 3 bottom surfaces of piston barrel offset, the cylinder is closed, the realization is pressed from both sides tightly.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
