Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and more specifically, to an automatic detection device for a seat gas pressure rod. Background Art

[0002] Seat gas pressure rods, also known as pneumatic lifting and telescopic adjusters or pneumatic springs, are elastic elements with gas and liquid as working media. They are mainly used for support, cushioning, braking, height adjustment and angle adjustment. They are composed of a pressure tube, a piston, a piston rod and several connecting parts. They are filled with high-pressure nitrogen. The working principle of the gas pressure rod is based on the gas pressure difference. The elastic force is generated through the different cross-sectional areas at both ends of the piston, thereby achieving lifting and lowering adjustment. Pneumatic rods are widely used in medical equipment, automobiles, furniture, textile equipment, processing industries and other fields.

[0003] During the production process of seat gas pressure rods, operators often use corresponding testing equipment to perform inspection operations on the seat gas pressure rods. Although the existing testing equipment has basic testing functions in actual use, general testing equipment usually uses bolts and nuts for fixing. This fixing method is not only inefficient, but also has complicated steps, which increases the labor intensity of operators. Therefore, it needs to be improved. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides an automatic detection device for a seat gas pressure rod, including a base plate 1, the front and rear sides of the bottom of the base plate 1 are fixedly connected to a fixing plate 2, the front of the fixing plate 2 is fixedly connected to a driving motor 3, the other end of the output shaft of the driving motor 3 is fixedly sleeved with a double-threaded rod 4, the other end of the double-threaded rod 4 passes through the fixing plate 2 and extends to the interior of the fixing plate 2 and is threadedly sleeved with a moving block 5, a No. 1 limit rod 6 is fixedly connected between the fixing plates 2, the interior of the top of the moving block 5 is movably sleeved with the outer surface of the No. 1 limit rod 6, the outer surface of the moving block 5 is hinged with an oblique rod 7, the other end of the oblique rod 7 is hinged with a connecting block 8, a rectangular groove 9 is provided on both sides of the double-threaded rod 4 at the bottom of the base plate 1, the interior of the rectangular groove 9 is movably connected to the outer surface of the connecting block 8, the top of the connecting block 8 is fixedly connected with a clamping plate 10, and the bottom of the clamping plate 10 is movably connected to the top of the base plate 1.

[0023] When the driving motor 3 starts running, the double-threaded rod 4 will rotate, and the two moving blocks 5 will move horizontally away from each other under the limiting action of the No. 1 limiting rod 6, thereby causing the two oblique rods 7 to move. At this time, under the limiting action of the rectangular slot 9, the two connecting blocks 8 drive the two clamping plates 10 to move horizontally toward each other.

[0024] Among them, both sides of the top of the bottom plate 1 are fixedly connected with a fixing frame 15, the left side of the fixing frame 15 is fixedly connected with a power motor 11, and the other end of the output shaft of the power motor 11 is fixedly sleeved with a rotating shaft 12.

[0025] When the power motor 11 starts to run, the rotating shaft 12 will rotate.

[0026] The other end of the rotating shaft 12 passes through the fixing frame 15 and extends into the interior of the fixing frame 15 , where a gear 13 is fixedly sleeved thereon. A toothed plate 14 is meshedly connected to the outer surface of the gear 13 .

[0027] When the rotating shaft 12 rotates, the gear 13 rotates and the toothed plate 14 moves upward.

[0028] Among them, there are two fixing frames 15, and the interiors of the two fixing frames 15 are movably connected with a No. 1 connecting plate 16 and a No. 2 connecting plate 17. The tops of the No. 1 connecting plate 16 and the No. 2 connecting plate 17 are fixedly connected with a mounting plate 18, and the bottom of the No. 2 connecting plate 17 is fixedly connected to the top of the tooth plate 14.

[0029] When the tooth plate 14 moves upward, the No. 1 connecting plate 16 and the No. 2 connecting plate 17 drive the mounting plate 18 to move vertically upward under the limiting action of the fixing frame 15 .

[0030] The top of the mounting plate 18 is fixedly connected to a pneumatic cylinder 19 , and the bottom end of the pneumatic cylinder 19 passes through the mounting plate 18 and extends to the bottom of the mounting plate 18 and is fixedly connected to an electromagnet 20 .

[0031] When the pneumatic cylinder 19 starts to operate, the electromagnet 20 will move vertically downward.

[0032] The bottom of the electromagnet 20 is movably connected to a movable plate 21 , which is made of stainless steel. The bottom of the movable plate 21 is fixedly connected to a counterweight block 23 .

[0033] When the electromagnet 20 is powered off, it loses its magnetism and the gravity of the counterweight 23 causes the movable plate 21 to move downward.

[0034] Among them, the two sides of the top of the movable plate 21 are fixedly connected with the second limiting rod 22. The top end of the second limiting rod 22 passes through the mounting plate 18 and extends to the outside of the mounting plate 18 and is movably connected to the inside of the mounting plate 18.

[0035] Under the limiting action of the second limiting rod 22 , the movable plate 21 will move vertically up and down.

[0036] The working principle and use process of this utility model:

[0037] First, place the seat pneumatic rod to be tested on the top of the base plate 1, and then start the drive motor 3, which will cause the double-threaded rod 4 to rotate, and the two moving blocks 5 will move horizontally opposite to each other under the limiting action of the No. 1 limit rod 6, thereby causing the two oblique rods 7 to move. At this time, under the limiting action of the rectangular groove 9, the two connecting blocks 8 drive the two clamping plates 10 to move horizontally toward each other, which will eventually achieve the fixing effect of the pneumatic rod, improve the efficiency of the operator in fixing the pneumatic rod, and reduce the labor intensity of the operator.

[0038] When the fixation is completed, the electromagnet 20 is turned off, which will cause the electromagnet 20 to lose its magnetism, and under the gravity of the counterweight 23, the movable plate 21 drives the second limit rod 22 under the limiting action of the mounting plate 18 to move vertically downward. When the counterweight 23 contacts the pneumatic rod, the pneumatic cylinder 19 is started, causing the electromagnet 20 to move vertically downward. When the electromagnet 20 contacts the movable plate 21, the electromagnet 20 is turned on again, so that the electromagnet 20 recovers its magnetism, and the pneumatic cylinder 19 is started again, so that the electromagnet 20 drives the movable plate 21 and the counterweight 23. It moves vertically upward, thereby realizing the reset function. When the test pressure to be performed is large and the initial height of the equipment is insufficient, the power motor 11 is started at this time, which will cause the rotating shaft 12 to drive the gear 13 to rotate, and cause the tooth plate 14 to move upward. At this time, under the limiting action of the fixing frame 15, the second connecting plate 17 will drive the mounting plate 18 and the first connecting plate 16 to move vertically upward, thereby realizing the purpose of adjusting the height of the mounting plate 18, so that the equipment can perform pressure tests of corresponding sizes on pneumatic rods of different sizes, thereby improving the application range of the equipment.
