DETAILED DESCRIPTION
[0019] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-5 The utility model provides a technical solution: a pneumatic positioner fixture, which includes a base 1 with a motor 5 and a main slider 3 and a sub-slider 4 relatively arranged on the base 1; a screw 2 for assembling the main slider 3 and the sub-slider 4 and plugged with the motor 5 is clamped on the base 1, and the main slider 3 and the sub-slider 4 move relatively on the base 1 through the screw 2, and an air storage cavity 6 is arranged in the inner cavity ring of the base 1, and an air inlet 7 for connecting to the air storage cavity 6 is arranged at one end of the base 1, and a plurality of telescopic air pipes 8 connected to the air storage cavity 6 are arranged at both ends of the base 1, and a plurality of air pipes 8 for connecting to the air storage cavity 6 are plugged on one side of the main slider 3 and the sub-slider 4. The telescopic air pipe 8 corresponds to the plug-in pneumatic telescopic rod 9, one end of the pneumatic telescopic rod 9 is plugged with a push rod 10, and a spring 11 is provided between the push rod 10 and the pneumatic telescopic rod 9; this embodiment has two operating methods: pneumatic clamping, the air inlet 7 is connected to the external air source to infuse gas into the air storage chamber 6, so that the pneumatic telescopic rods 9 on the main slider 3 and the auxiliary slider 4 obtain air energy through the air storage chamber 6 and thus extend, and the weldment is clamped by the push rod 10; electric clamping, the screw 2 is rotated by the motor 5 so that the main slider 3 and the auxiliary slider 4 slide relative to each other and approach each other, and the weldment is clamped on the base 1 by the push rod 10.
[0021] See also Figure 1-5In this embodiment, there are two screw rods 2 with the same shape and structure. The base 1 is provided with a first guide groove 12 and a second guide groove 13 for respectively assembling the two screw rods 2. The inner wall of the first guide groove 12 is provided with a first sub-groove 20, and the inner wall of the second guide groove 13 is provided with a second sub-groove 21. The main slider 3 and the auxiliary slider 4 have similar shapes and structures, wherein one side of the bottom end of the main slider 3 is provided with a first screw hole 23 for screwing one of the screw rods 2, and the other end thereof is provided with a first guide block 25 for clamping the first sub-groove 20. One side of the bottom end of the auxiliary slider 4 is provided with a second screw hole 24 for screwing the other screw rod 2, and the other end thereof is provided with a second guide block 26 for clamping the second sub-groove 21. It is worth noting that one end of the base 1 is provided with a connecting cavity 14, and the connecting cavity 14 is provided with main gears meshing with each other. 15 and secondary gear 16, two screw rods 2 are respectively inserted into the connecting cavity 14, wherein one end of the screw rod 2 arranged in the first guide groove 12 is clamped with the main gear 15, and one end of the screw rod 2 arranged in the second guide groove 13 is clamped with the secondary gear 16, one end of the main slider 3 is screwed on the screw rod 2 clamped with the main gear 15, and one end of the secondary slider 4 is screwed on the screw rod 2 clamped with the secondary gear 16, and the motor 5 is started, so that the two screw rods 2 rotate in opposite directions through the main gear 15 and the secondary gear 16. Since the main slider 3 and the secondary slider 4 are respectively threadedly connected to the two screw rods 2, the rotation of the screw rod 2 will be converted into linear motion of the main slider 3 and the secondary slider 4, and the rotation directions of the two screw rods 2 are opposite, so that the main slider 3 and the secondary slider 4 slide relative to each other, which is convenient for user operation.
[0022] See also Figure 1-5 One end of the push rod 10 is provided with an assembly cavity 17 for assembling the spring 11, the outer surface of the pneumatic telescopic rod 9 is provided with a slide groove 18, and the inner wall of the assembly cavity 17 is provided with a fixing block 19 for slidingly connecting with the slide groove 18. The pneumatic telescopic rod 9 and the push rod 10 are correspondingly plugged through the assembly cavity 17, and one end of the pneumatic telescopic rod 9 abuts against one end of the spring 11, so that elasticity is generated between the pneumatic telescopic rod 9 and the push rod 10. When clamping an irregular welded part, the push rod 10 abutting against the welded part compresses the spring 11 and clamps the welded part, and the push rod 10 that does not abut against the welded part abuts against each other to compress the spring 11, so that the device can clamp the irregular welded part according to the elastic force generated between the pneumatic telescopic rod 9 and the push rod 10 without adjusting the corresponding clamping plate to the clamping position according to the shape of the object, thereby effectively enhancing the clamping accuracy of this embodiment.
[0023] Working principle: Pneumatic clamping, the air port 7 is connected to the external air source to infuse the gas into the air storage chamber 6, so that the pneumatic telescopic rods 9 on the main slider 3 and the auxiliary slider 4 can obtain the air energy in the air storage chamber 6 through the telescopic air pipe 8 and thus extend, and clamp the weldment through the ejector rod 10;
[0024] Electric clamping, starting the motor 5 rotates the two screws 2 through the main gear 15 and the secondary gear 16 so that the main slider 3 and the auxiliary slider 4 slide relative to each other and approach each other, so that the weldment is clamped on the base 1 through the push rod 10.
