[0030] The technical solution in the embodiment of the application provides a quick radial dismounting coupling, and solves the technical problem that frequent dismounting of the coupling affects the measurement accuracy of the screw rod measurement mechanism in the prior art.

[0031] The technical solution in the embodiment of the application has the following general idea to solve the above technical problem:

[0032] For example, the coupling provided in the application is a quick radial dismounting coupling. Figures 1-7As shown, the application provides a quick radial disassembly coupling, comprising a lower connecting block 1, a middle connecting block 2 and an upper connecting block 3, the middle connecting block 2 is arranged on the end face of the upper connecting block 3, the end face of the lower connecting block 1 is provided with a first sliding groove 11, the middle connecting block 2 is operatively matched with the first sliding groove 11, and the upper connecting block 3 is sleeved with a sliding sleeve 4, and the sliding sleeve 4 is operatively sleeved at the connection between the upper connecting block 3 and the lower connecting block 1.

[0033] The upper connecting block 3 and the lower connecting block 1 are connected through the matching relationship of the middle connecting block 2 and the first sliding groove 11, which facilitates the quick radial disassembly of the coupling, and enables the axial positioning of the upper connecting block 3 and the lower connecting block 1 to be accurate, and at the same time, the upper connecting block 3 and the lower connecting block 1 are limited by the sliding sleeve 4 to prevent displacement between the upper connecting block 3 and the lower connecting block 1.

[0034] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the description of the drawings and the specific embodiments.

[0035] Preferably, the diameter of the sliding sleeve 4 is the same as the diameter of the lower connecting block 1, and the lower connecting block 1 is provided with a step 12 at the side position corresponding to the sliding groove, and in the installation process, the sliding sleeve 4 is operatively sleeved on the step 12, so that the outer side of the coupling formed by the combination of the upper connecting block 3 and the lower connecting block 1 can be smoother.

[0036] As shown in the figure, Figure 5 The middle connecting block 2 comprises a connecting plate 21, a first sliding block 22 and a second sliding block 23, the first sliding block 22 and the second sliding block 23 are respectively fixedly arranged on the two end faces of the connecting plate 21, the first sliding block 22 is operatively inserted into the first sliding groove 11, and the end face of the upper connecting block 3 is provided with a second sliding groove 31, and the second sliding block 23 is operatively inserted into the second sliding groove 31.

[0037] Specifically, the two ends of the first sliding block 22 and the second sliding block 23 are arc-shaped, and the arc-shaped arrangement of the two ends of the first sliding block 22 and the second sliding block 23 can facilitate the installation of the middle connecting block 2, the upper connecting block 3 and the lower connecting block 1.

[0038] Further, the first sliding block 22 and the second sliding block 23 are arranged perpendicular to each other, which provides different disassembly directions for the coupling.

[0039] Preferably, as shown in the figure, Figure 8 The sliding sleeve 4 is provided with a protection part 42 inside corresponding to the first sliding groove 11 and the second sliding groove 31, and the protection part 42 is a rubber layer or a wear-resistant layer.

[0040] In the actual installation process, when the protective part 42 is a rubber layer, the length of the first sliding block 22 and the second sliding block 23 is less than the length of the first sliding groove 11 and the second sliding groove 31, when the sliding sleeve 4 is fixed with the upper connecting block 3 and the lower connecting block 1, the rubber layer is clamped into the corresponding first sliding groove 11 and the second sliding groove 31, which limits the left and right of the sliding sleeve 4, and the rubber layer can buffer the first sliding block 22 and the second sliding block 23, prevent the dislocation between the upper connecting block 3, the middle connecting block 2 and the lower connecting block 1, and prevent the powder from entering the first sliding groove 11 and the second sliding groove 31.

[0041] When the protective part 42 is a wear-resistant layer, specifically a wear-resistant metal, including high manganese steel, stainless steel, chromium molybdenum alloy steel, high speed steel and the like, when the sliding sleeve 4 is installed to the specified position, if the first sliding block 22 and the second sliding block 23 move radially, the wear-resistant layer can protect the first sliding block 22 and the second sliding block 23, reduce the wear and prolong the service life.

[0042] Further, as shown in Figure 1 、 Figure 3 , the side surface of the sliding sleeve 4 is provided with two long holes 41 along the axial direction, the two long holes 41 are penetrated in the radial direction of the sliding sleeve 4, the upper connecting block 3 is provided with a pin 6 along the radial direction, the pin 6 is inserted into the long hole 41, the sliding sleeve 4 is installed in the upper connecting block 3, and the sliding sleeve 4 is limited by the pin 6 and the long hole 41 to prevent the sliding sleeve 4 from falling off after the coupling is disassembled.

[0043] Further, as shown in Figures 1-4 、 Figure 6 , the upper connecting block 3 is fixedly provided with a baffle 32 away from the lower connecting block 1, the upper connecting block 3 is sleeved with a spring 5, and the spring 5 is located between the baffle 32 and the sliding sleeve 4. After the upper connecting block 3 and the lower connecting block 1 are installed, the sliding sleeve 4 is pressed on the step 12 of the lower connecting block 1 by the elastic force of the spring 5, so that the phenomenon of the sliding sleeve 4 being separated is prevented during the working process of the coupling.

[0044] Optionally, the sliding sleeve 4 is provided with a sealing ring at both ends inside, so that the powder is prevented from entering the gap between the sliding sleeve 4, the upper connecting block 3 and the lower connecting block 1.
