The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the technical solution provided by the present invention is: a pneumatic clamp for electrical mechanical equipment comprises a support plate 1 and a cylinder 3; the air cylinder 3 is fixedly connected to the upper surface of the supporting plate 1, the inner wall of the air cylinder 3 is connected with a piston rod 7 in a sliding mode, and air holes are formed in two ends of the top of the air cylinder 3;

the upper surface of the supporting plate 1 is provided with a clamping component 2; the clamping component 2 is used for clamping a part; the clamping assemblies 2 comprise two groups, one group of the clamping assemblies 2, which is far away from the cylinder 3, is fixedly connected to the upper surface of the supporting plate 1, and the bottom of the other group of the clamping assemblies 2 is arranged in a sliding connection with the upper surface of the supporting plate 1; the clamping assembly 2 comprises a shell 201, a shaping rod 202, a partition plate 204, a vent pipe 205, a rubber ring 206, a baffle 207, a rubber plug 208 and a supporting spring 209; one end of the shell 201, which is far away from the cylinder 3, is provided with a rectangular opening, and one end of the piston rod 7 is fixedly connected with the outer surface of the shell 201; the partition plate 204 is fixedly connected with the inner surface of the shell 201, the vent pipe 205 is of a cylindrical pipeline structure with two open ends, the shaping rod 202 is arranged at the open end of the shell 201, the shaping rod 202 is inserted into the vent pipe 205 and is arranged in a sliding connection manner with the vent pipe 205, the inner surface of one end of the vent pipe 205 close to the cylinder 3 is fixedly connected with the rubber ring 206, a supporting spring 209 is arranged inside the vent pipe 205, and two ends of the supporting spring 209 are respectively and fixedly connected with the bottom end of the shaping rod 202 and the top end of the rubber ring 206; one side of baffle 207 near cylinder 3 sets up with shell 201 inner wall sliding connection, and baffle 207 opposite side fixedly connected with a plurality of rubber stoppers 208.

Thus, before clamping the part, the rubber ring 206 and the rubber stopper 208 are in a staggered state, so that the vent pipe 205 is in an open state, and the shaping rod 202 is kept extending under the action of the supporting spring 209; when the shaping rod 202 clamps a part for the first time, the baffle 207 is pressed down, the rubber plug 208 blocks the rubber ring 206, the vent pipe 205 is in a sealing state at the moment, the shaping rod 202 is fixed in the vent pipe 205 under the action of air pressure, the shaping rods 202 form the shape of clamping the part, then the clamping assembly 2 can do reciprocating motion, and the clamp can specially clamp the part with the shape at the moment; when other parts need to be replaced, the baffle 207 is pulled upwards to release the sealing state of the vent pipe 205, and the operation is repeated again.

Referring to fig. 1, a driving assembly 4 is disposed on an upper surface of the supporting plate 1; the drive assembly 4 comprises a conduit 401, a solenoid valve 402, two exhaust ports 403, an air inlet 404, two air outlet ports 405 and a switch 406; the electromagnetic valve 402 is fixedly connected to the upper surface of the support plate 1, the electromagnetic valve 402 is electrically connected with an external power supply, an air outlet 405 is formed in one end, close to the air cylinder 3, of the electromagnetic valve 402, two ends of the guide pipe 401 are respectively and fixedly connected with the air outlet 405 and an air vent at the top end of the air cylinder 3, and an air outlet 403 and an air inlet 404 are formed in one end, far away from the air cylinder 3, of the electromagnetic valve 402; the solenoid valve 402 has a switch 406 disposed on an outer surface thereof, and the switch 406 is electrically connected to the solenoid valve 402.

Thus, by opening the switch 406, the electromagnetic valve 402 is energized, compressed air enters from the air inlet 404, and then the compressed air is transmitted to the air cylinder 3 from the conduit 401 in the air outlet 405 far away from the clamping assembly 2, so that the piston rod 7 is pushed by the compressed air to slide outwards, the clamping assembly 2 is pushed to slide forwards along the slide rail 6 and the limiting plate 5, after the clamping assembly 2 is shaped, the switch 406 is closed, at this time, the air is exhausted from the conduit 401 through the air outlet 403, the air pressure in the air cylinder 3 is restored to be stable, and therefore the piston rod 7 is reset and returns to the initial state; repeating the above operations of switching on and switching off the power supply again, the piston rod 7 can be realized to push the clamping component 2 to do reciprocating motion, and finally the solenoid valve 402 is used for controlling the cylinder 3 to match with the shaping function of the clamping component 2, so that the shapeable pneumatic clamp with a simple structure is realized.

Referring to fig. 1 and 3, a handle 203 is disposed on the outer surface of the top end of the housing 201; the bottom of the handle 203 penetrates the top end of the shell 201, and the bottom of the handle 203 is fixedly connected with the top end of the baffle 207.

Therefore, the baffle 207 is arranged inside the shell 201, the baffle 207 is not suitable for being applied in production by directly pressing or pulling, the handle 203 is designed on the outer surface of the shell 201, operation is facilitated, and working efficiency is improved.

Referring to fig. 1 and 3, the upper surface of the supporting plate 1 is fixedly connected with a slide rail 5 and two limiting plates 6, the limiting plates 6 are arranged in an L-shaped structure, and the lower surface of the housing 201 is slidably connected with the upper surface of the slide rail 5.

Thus, when the handle 203 is pressed or pulled out, the acting force in the vertical direction exists, and the limiting plate 6 is required to resist the acting force; the clamping assembly 2 can be normally used only by being transversely aligned, so that the sliding rail 5 and the limiting plate 6 act together, the clamping assembly 2 is prevented from deviating, and the normal operation of the device is ensured.

Referring to fig. 2 and 3, the outer diameter of the shaping rod 202 is equal to the inner diameter of the vent tube 205, and the length of the shaping rod 202 is greater than the length of the vent tube 205.

Thus, since the device requires strict sealing conditions when formed into a specific shape and requires the shaping rod 202 to be slidably connected to the inner surface of the vent tube 205, the outer diameter of the shaping rod 202 is set to be equal to the inner diameter of the vent tube 205; and the bottom of the shaping rod 202 is provided with a supporting spring 209, the length of the shaping rod 202 needs to be set to be larger than that of the vent pipe 205 to avoid over-pressing the shaping rod 202.

Referring to fig. 1, the length of the slide rail 5 and the limiting plate 6 is greater than the length of the piston rod 7.

Therefore, the maximum distance of the forward sliding of the clamping component 2 is the length of the piston rod 7 in a telescopic manner, so that when the length of the sliding rail 5 and the limiting plate 6 is greater than that of the piston rod 7, the clamping component 2 can be ensured not to deviate at the limit position.

Referring to fig. 2 and 3, the top end of the rubber plug 208 is spherical, and the inner diameter of the rubber ring 206 is smaller than the diameter of the spherical top end of the rubber plug 208.

Thus, only when the inner diameter of the rubber ring 206 is smaller than the diameter of the top end of the rubber plug 208, the complete sealing performance of the vent pipe 205 can be achieved, and the arrangement enables the device to have good fault tolerance.
