[0002] With the rapid development of the scientific and technological era, mechanical automation has developed rapidly, and the combination and coordination of machines has gradually replaced manual operation. For the production and processing of various things, the automation industry uses mechanical claws to clamp objects, or uses suction cups and other methods to move objects. The mechanical claw clamping method is often used to move hard objects, and the suction cup adsorption method is often used for objects with good sealing properties.
[0003] In the automation industry, when grabbing non-woven fabrics, felts and other types of items, the mechanical grabbing method is difficult to clamp stably and is easy to fall due to the elasticity of non-woven fabrics and felts themselves, while the suction cup adsorption cannot adsorb non-woven fabrics and will cause air leakage.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0022] Please see attached Figure 1-Figure 4 The utility model provides a multifunctional gas needle clamp, which comprises:
[0023] A transmission box 1 is provided with a cylinder 2 at the center of the bottom surface of the transmission box 1, the cylinder 2 is connected to the inside of the transmission box 1 and is transmission-connected to provide driving force for the inside of the transmission box 1, needle boxes 3 are obliquely fixed on both sides of the top surface of the transmission box 1, and an adsorption air hole 4 is opened at the center of the top surface of the transmission box 1 for adsorption of suction cup-type items, and symmetrical push-pin outlet holes 5 are obliquely opened on both sides of the adsorption air hole 4, the inside of the push-pin outlet holes 5 is connected with the inside of the needle box 3, and a needle seat 8 is slidably connected to the inside of the needle box 3, and two symmetrical groups of clamping needles 6 are fixed inside the needle seat 8, and the clamping needles 6 slide on the inside of the push-pin outlet holes 5, and the needle seat 8 is driven to slide by the cylinder 2, so that the clamping needles 6 can penetrate in two directions and grab items such as non-woven fabrics and felts.
[0024] Transmission gears 7 are rotatably connected on both sides of the transmission box 1. The top of the transmission gear 7 meshes with the bottom of the needle seat 8 for driving the needle seat 8 synchronously. The bottom of the transmission gear 7 is connected to the cylinder 2 for power transmission from the cylinder 2 to the transmission box 1.
[0025] A pneumatic push rod 9 is inserted into the cylinder 2 and slides in a sealed manner on the inner side of the cylinder 2. A pneumatic gear rod 10 is sealed on the top of the pneumatic push rod 9. The top of the pneumatic gear rod 10 is meshed with the transmission gear 7. The pneumatic drive of the cylinder 2 pushes the pneumatic push rod 9 up and down, converting the pneumatic force into mechanical power, driving the transmission gear 7 to rotate, and completing the bidirectional synchronous displacement of the needle seat 8.
[0026] The outer walls of the bottom of the pneumatic push rod 9 and the pneumatic gear rod 10 are fitted with sealing rings 11 to seal and slide on the inner wall of the cylinder 2, thereby improving the pneumatic drive sealing effect inside the cylinder 2. The driving tooth block 12 arranged on the top circumference of the pneumatic gear rod 10 is meshed with the transmission gear 7, so that the pneumatic gear rod 10 can complete the rotation of the transmission gear 7 while lifting and lowering.
[0027] A sealing air nozzle 13 is fixed on the inner side of the adsorption air hole 4. The sealing air nozzle 13 is made of rubber material. Through the design of the rubber air nozzle, the suction sealing of the adsorption air hole 4 can be increased. At the same time, the bottom of the rubber air nozzle is connected to the pneumatic push rod 9, which can increase the adsorption sealing effect of the pneumatic push rod 9.
[0028] Usage process:
[0029] The pneumatic cylinder 2 pneumatically moves down through the pneumatic push rod 9, which can make the pneumatic gear rod 10 move down synchronously. When the pneumatic gear rod 10 moves down, it will drive the transmission gear 7 to rotate, allowing the transmission gear 7 to drive the needle seat 8 inside the needle box 3 to slide upward. Through the upward sliding of the needle seat 8, the clamping needle 6 is allowed to pass through the needle push hole 5 and pierce to the outside, thereby completing the insertion of the fabric. The insertion method is a two-way staggered insertion, and the insertion stability is stronger. At the same time, controlling the piercing distance of the clamping needle 6 can change the amount of fabric grabbed.
[0030] When the device needs to grab adsorbable items, the pneumatic push rod 9 inside the pneumatic cylinder 2 moves up, so that the top of the pneumatic push rod 9 is sealed and connected with the sealing air nozzle 13 inside the adsorption air hole 4. At this time, the cylinder 2 can form suction by sucking air through the pneumatic push rod 9, and the sealing air nozzle 13 is used to complete the adsorption and clamping of the object.
