[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction and be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 As shown, the size detection device of the piston rod of the utility model includes a detection platform 1 and a supporting claw, a lower supporting claw 16, a limiting claw 52, ​​and a front supporting claw 71 that are arranged in cooperation. A strip board 11 is fixedly installed at the rear of the detection platform 1, and a rear supporting claw 43 is fixedly installed at the left end of the strip board 11 through a first bracket 3. The strip board 11 on the right side of the rear supporting claw 43 is also provided with a scale line on the detection platform 1 on the front side of the slide rail 2.

[0028] A limiting claw 52 is installed on the slide rail 2 through the first slider 5, and the limiting claw 52 is connected to the first slider 5 through the second bracket 51. A limiting plate 53 is fixedly installed on the right part of the limiting claw 52, ​​and a limiting plate 12 cooperating with the rear supporting claw 43 is also installed on the detection table 1 on the left side of the rear supporting claw 43; when detecting the length of the piston rod, the left end of the piston rod can be abutted against the surface of the limiting plate 12, and the limiting plate 53 can be abutted against the right end face of the piston rod, and the length can be directly read through the scale line, which is convenient for measuring the length.

[0029] The lower support claw 16 is installed on the test bench 1 on the right side of the rear support claw 43 through the column 15, and the column 15 is fixedly installed on the test bench 1 through the rubber seat 14; Figure 1-2 As shown, the front support claw 71 is installed on the detection table 1 at the front side of the lower support claw 16 through the support member 13, and the support member 13 is provided with a mounting hole, the front support claw 71 is arranged at the rear of the mounting hole through the slide bar 7, the front of the mounting hole is installed with a screw rod 6 matched with the slide bar 7, and the rear of the screw rod 6 is installed with a handle;

[0030] The rear support claw 43, the lower support claw 16, the limit claw 52 and the front support claw 71 are all arc-shaped structures, and when the rear support claw 43, the lower support claw 16, the limit claw 52 and the front support claw 71 cooperate, the cylindrical piston rod can be fixed on the detection device. When the piston rod is placed on the lower support claw 16, the front support claw 71 can be pressed against the piston rod by rotating the screw rod 6 by the handle. As the screw rod 6 rotates, the piston rod is pressed against the rear support claw 43 and the limit claw 52, ​​and the column 15 is installed on the detection table 1 through the rubber seat 14, so that when the piston rod is pressed against the rear support claw 43, the lower support claw 16 can be offset to prevent the piston rod from being difficult to detach from the lower support claw 16.

[0031] like Figure 1 and 3 As shown, a second slider 4 is also installed on the slide rail 2 between the first slider 5 and the rear supporting claw 43, and a detection claw is installed on the second slider 4 through a support body 41. The detection claw is made of polytetrafluoroethylene, which can avoid wear on the surface of the piston rod when the detection claw slides; the detection claw is arranged in coordination with the rear supporting claw 43 and the limiting claw 52, ​​and a slideway is provided on the support body 41. The detection claw is installed on the slideway through a support rod 42, and a pressure sensor 46 and a spring 47 that cooperate with the support rod 42 are provided at the bottom of the slideway. A display panel 45 and a battery pack 44 are also provided on the support body 41. The battery pack 44 is electrically connected to the display panel 45, and the display panel 45 is electrically connected to the pressure sensor 46.

[0032] When the piston rod is fixed on the front supporting claw 71, the rear supporting claw 43 and the limiting claw 52, ​​the sliding detection claw moves on the surface of the piston rod. If the piston rod is bent, the pressure value of the pressure sensor 46 will change significantly, and the value on the display panel 45 can be intuitively observed and judged. It should be noted that when detecting whether the piston rod is bent, the piston rod needs to be rotated 90° for detection after detection to avoid the situation where the piston rod is bent downward or upward and it is impossible to accurately judge whether the bending degree of the piston rod meets the use requirements.

[0033] In addition, there are two front support claws 71 and two lower support claws 16. The two front support claws 71 can be set between the two lower support claws 16 to facilitate detection operations and fix the piston rod, and the rear support claw 43, the lower support claw 16, the limit claw 52 and the front support claw 71 are made of metal to avoid deformation of the rear support claw 43, the lower support claw 16, the limit claw 52 and the front support claw 71 when clamping the piston rod.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
