Problems solved by technology

[0004] The present invention overcomes the problem that the trachea intertwining and knotting of the pneumatic clamping tool in the prior art will affect the clamping effect during multiple sets of simultaneous operations, and the trachea will melt after contacting the high-frequency heating coil when the tool is in the high-frequency heating station. In the process of switching between each other, the gas pipe is pinched by the associated action mechanism. An offline pneumatic clamping tool is provided, which cancels the gas pipe connection between the pneumatic clamping tool and the factory air source, and the clamping tool is in the clamping process. During the process, the air pipe can be separated and moved freely, effectively avoiding the entanglement and knotting of the air pipes during the simultaneous operation of multiple sets of fixtures, which will affect the clamping effect. In the process of mutual switching, the air pipe is pinched by the associated action mechanism, etc., and the operation of the clamping tool to clamp and loosen the product is simple

Embodiment 2

[0028] Such as figure 2As shown, on the basis of Embodiment 1, the three-way valve 6 is a manual three-way valve 6, and the three-way valve 6 includes a fixed block 6.1, a sliding block 6.2 and a second spring 6.3, and the fixed block 6.1 is provided with a chute 6.1. 1. The sliding block 6.2 is adapted to the chute 6.1.1. The sliding block 6.2 is set in the chute 6.1.1 and is slidably connected with the fixed block 6.1. One end of the sliding block 6.2 extends out of the chute 6.1.1, and the second spring 6.3 One end is connected with the fixed block 6.1, the other end of the second spring 6.3 is connected with the sliding block 6.2, the fixed block 6.1 is provided with the first air port 6.1.2, the second air port 6.1.3 and the third air port 6.1.4, the sliding block 6.2 There is a linkage groove 6.2.1 on it, and the linkage groove 6.2.1 communicates with the first air port 6.1.2 and the second air port 6.1.3 or communicates with the first air port 6.1.2 and the third air p...

Embodiment 3

[0030] Such as image 3 As shown, on the basis of Embodiment 1, an inflator 9 is also included. The inflator 9 includes an air cylinder 9.1, a piston rod 9.2 and a second one-way valve 9.3. The air outlet of 9.1 communicates with the inflatable block 4, and the second one-way valve 9.3 is arranged on the air inlet of the air cylinder 9.1. The air cylinder 9.1 is arranged laterally on the support frame 1, and the sliding direction of the piston rod 9.2 is the same as the telescopic direction of the clamping cylinder 3. The piston rod 9.2 is provided with an operating pad, and the inner diameter of the air cylinder 9.1 is smaller than that of the clamping cylinder 3 .

[0031] The inflation device 9 can inflate the inflation block 4, and the clamping tool does not need an additional inflation gas source, which is more convenient to operate. Pushing the piston rod 9.2 can realize the inflation function during use. The arrangement of the gas cylinder 9.1 can make the structure ...

Abstract

The invention discloses an offline pneumatic clamping tool which comprises a supporting frame, a moving rod, a clamping air cylinder, an inflation block, a first one-way valve, a three-way valve and atelescopic spring. The moving rod is slidably connected with the supporting frame, one end of the telescopic spring is connected with the supporting frame, the other end of the telescopic spring is connected with the moving rod, and the clamping air cylinder is fixed to the supporting frame; a telescopic rod of the clamping air cylinder is connected with the moving rod, the inflation block communicates with the three-way valve, the first one-way valve is arranged in the inflation block, and the clamping air cylinder communicates with the three-way valve; and the supporting frame is provided with a plurality of positioning grooves for placing products, the moving rod is provided with a plurality of clamping pieces for clamping the products, and the clamping pieces correspond to the positioning grooves in a one-to-one mode. According to the offline pneumatic clamping tool, air pipe connection between the pneumatic clamping tool and a factory air source is omitted, the clamping tool canbe separated from an air pipe in a clamping process, and the clamping tool is easy to clamp and loosen the products.

Description

technical field [0001] The invention relates to the field of pneumatic clamping equipment, in particular to an off-line pneumatic clamping equipment. Background technique [0002] Before the high-frequency heating of the electric heating tube, the products must be placed in an orderly manner, and then transferred to the high-frequency heating station after being clamped by the clamping tool. Most of the existing clamping fixtures are pneumatic clamping fixtures with air pipes connected to the air source. During the production process, multiple sets of fixtures need to be used for switching operations. The air intake pipes and outlet pipes of multiple sets of fixtures are connected to the same air source interface. In the existing pneumatic clamping tooling, the trachea will be entangled and knotted during the simultaneous operation of multiple sets, which will affect the clamping effect. When the tooling is in the high-frequency heating station, the trachea will melt after t...
