DETAILED DESCRIPTION

[0018] 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.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0020] Combination Figure 1 A constant speed drive shaft pressure length detection device includes a base 1, a limit plate 2 and a sliding part 4 for sliding the drive shaft are arranged on the upper end of the base 1, and a fixing part 3 for fixing the drive shaft is slidably connected to the upper end of the sliding part 4.

[0021] The utility model is further described below in conjunction with embodiments.

[0022] Example 1: Please refer to Figure 1 and Figure 3 The fixed part 3 includes a sliding plate 31 slidably connected to one side of the fixed part 3, and the sliding plate 31 is fixedly connected in two groups. The upper ends of the two groups of sliding plates 31 are fixedly connected to support rods 32, and the upper ends of the support rods 32 are fixedly connected to mounting plates 33, and the upper ends of the mounting plates 33 are fixedly connected to grippers 34 and springs 36, and the upper ends of the springs 36 are fixedly connected to sponge pads 35. The grippers 34 are fixedly connected in two groups.

[0023] Specifically, the drive shaft is placed between two groups of clamps 34, and the fixed connection of the limit plate 2 can limit the drive shaft. The size between the clamps 34 is adjusted according to the size of the drive shaft to fix the drive shaft. The sponge pad 35 can protect the drive shaft, and when other structures vibrate during movement, the spring 36 can play a buffering role, so that the drive shaft does not shake due to vibration, thereby improving the stability of the drive shaft fixation and reducing the measurement error.

[0024] Example 2: Please refer to Figure 1-Figure 4A slot 341 is provided on the inner side of the gripper 34, a sponge is fixedly connected inside the slot 341, a sliding slot 38 is provided on one side of the sliding plate 31, the sliding portion 4 includes a fixed shaft 41 fixedly connected to the upper end of the base 1, the fixed shaft 41 is fixedly connected with two groups, the inner walls of the two groups of fixed shafts 41 are provided with fixed slots 44, the inner walls of the fixed slots 44 are fixedly connected with positioning shafts 42, the outer surfaces of the positioning shafts 42 are rotatably connected with balls 43, the sliding plate 31 is slidably connected to the fixed shaft 41 through the sliding slot 38, a telescopic cylinder 6 is fixedly connected to the upper end of the base 1, the telescopic end of the telescopic cylinder 6 is fixedly connected to the fixed plate 5, a sliding opening 51 is provided on one side of the fixed plate 5, the fixed plate 5 is slidably connected to the fixed shaft 41 through the sliding opening 51, a scale 7 is fixedly connected to the upper end of the base 1, and a pointer 37 is fixedly connected to the upper end of the sliding plate 31.

[0025] Specifically, the sponge is soft enough to protect the drive shaft and reduce the vibration caused by external movement. The position of the sliding plate 31 is adjusted according to the length of the driving shaft, and the sliding plate 31 is pushed to slide. The ball 43 contacts the sliding plate 31 and rolls. The ball 43 can reduce the friction and thus reduce the vibration of the sliding plate 31 caused by resistance during movement, thereby making the device more stable. After adjusting the position of the sliding plate 31, the telescopic cylinder 6 is extended to drive the fixed plate 5 to slide on the fixed shaft 41. The ball 43 contacts the fixed plate 6 and rolls, thereby making the sliding smoother and reducing the vibration caused by wear, until the fixed plate 5 contacts the sliding plate 31 and the telescopic cylinder 6 can no longer extend, thereby ensuring the accuracy of the measured length and reducing errors. The pointer 37 moves with the movement of the sliding plate 31 and points to the scale above the scale 7 to measure the length.
