Description

Technical Field

[0001] The utility model belongs to the technical field of drive shaft detection, and particularly relates to a detection placement rack for a spline shaft fork of a drive shaft. Background Technique

[0002] The spline shaft fork is an important component on a non-uniform speed drive shaft, which is concentrically and fixedly welded by a spline shaft and a shaft fork. Ear holes for connection are provided at the centers of both end faces of the shaft fork; after the spline shaft fork is processed, to ensure its quality, it is necessary to detect the position and symmetry of the ear holes and the external splines on the surface of the spline shaft fork to avoid problems such as inability to install during actual subsequent use due to size deviations; the traditional detection method is mainly that the detector directly measures the spline shaft fork with detection tools such as micrometers. In specific use, this method has low detection efficiency, and during the detection process, due to the lack of effective limit placement of the spline shaft, it is easy to affect the detection accuracy due to the movement of the spline shaft; therefore, to solve the above problems, it is necessary to develop a detection placement rack for a spline shaft fork of a drive shaft with high detection efficiency, good effect, and convenient operation and use. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a detection placement rack for a spline shaft fork of a drive shaft with high detection efficiency, good effect, and convenient operation and use.

[0004] The purpose of the utility model is achieved as follows: A detection placement rack for a spline shaft fork of a drive shaft includes a placement platform and an adjustment plate. The placement platform is horizontally arranged as a whole, a through hole is provided at its center, a controller is arranged at the left end of the upper surface, an installation block is fixedly arranged at the right end of the upper surface, and support plates are vertically and fixedly arranged on both sides of the lower surface. A detection rod is vertically and slidably penetrated through the through hole. The detection rod is cylindrical as a whole, and its diameter matches the diameter of the ear hole of the spline shaft fork. The lower end of the detection rod is located below the placement platform and is concentrically and fixedly connected with a screw rod. A detection sleeve is horizontally and rotatably penetrated through the center of the installation block, and an internal spline matching the external spline structure on the surface of the spline shaft fork is arranged on the inner surface of the detection sleeve; the adjustment plate is horizontally arranged directly below the placement platform, electric push rods are vertically arranged at both ends of its upper surface, and it is limit-connected with the placement platform through the electric push rods. The electric push rods are electrically connected with the controller through wires. A connection block is fixedly arranged at the middle position of the upper surface of the adjustment plate, and a thread groove matching the screw rod structure is arranged at the center of the upper surface of the connection block.

[0005] The upper end of the detection rod is a semi-circular structure.

[0006] The diameter of the screw rod is smaller than the diameter of the detection rod.

[0007] On the left side of the front end face of the placement platform, a detection note placement slot is fixedly arranged.

[0008] Advantages of the present utility model: By setting the mounting block and the detection sleeve, and using the cooperation between the internal spline on the inner surface of the detection sleeve and the external spline on the surface of the spline shaft fork, while the spline shaft fork can be horizontally limited and placed inside the present utility model as a whole, the size of the external spline on the surface of the spline shaft fork can also be detected to determine whether it is qualified. At the same time, by using the rotational connection between the detection sleeve and the mounting block, during the detection process, the detection sleeve and the spline shaft fork to be detected can be rotationally adjusted by an external force. When the ear holes of the spline shaft fork to be detected and the detection rod are in the same vertical plane, multi-angle inspection of its surface can also be achieved through the rotational adjustment of the spline shaft fork.

[0009] By setting the through hole, the controller, the detection rod, the screw rod, the adjusting plate, the electric push rod, the connecting block and the threaded groove, during use, the controller can be used to control the electric push rod to contract. Thus, through the contraction of the electric push rod, the adjusting plate, the connecting block and the detection rod are driven to move in the vertical direction. At this time, as the detection rod moves in the vertical direction, the size and symmetry of the ear holes can be judged according to the connection state between the detection rod and the ear holes on both sides of the spline shaft fork to be detected (if the detection rod can smoothly pass through the two ear holes in sequence, it indicates that the size and symmetry of the ear holes on both sides of the spline shaft fork are qualified; if the detection rod cannot pass through the two ear holes, or cannot smoothly pass through the upper ear hole after passing through the lower ear hole, it indicates that the size and symmetry of the ear holes on both sides of the spline shaft fork are unqualified). At the same time, by using the threaded connection between the threaded groove and the screw rod, the detachable installation between the detection rod and the adjusting plate can be realized. With this structure, when the detection rod is bent and deformed due to wear or collision during long-term use, the convenience of its replacement operation can be increased. Generally, the present utility model has the advantages of high detection efficiency, good effect, and convenient operation and use. Description of the Drawings

[0015] The following further describes the present utility model in conjunction with the accompanying drawings.

[0016] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a detection placement rack for a drive shaft spline shaft fork includes a placement platform 1 and an adjusting plate 2. The placement platform 1 is horizontally arranged as a whole. A through hole 11 is provided at its center. A controller 12 is provided at the left end of the upper surface. A mounting block 13 is fixedly provided at the right end of the upper surface. Support plates 14 are vertically and fixedly provided on both sides of the lower surface. A detection rod 15 is vertically and slidably inserted through the through hole 11. The detection rod 15 is cylindrical as a whole. Its diameter matches the diameter of the ear hole of the spline shaft fork. And the lower end of the detection rod 15 is located below the placement platform 1 and is concentrically and fixedly connected with a screw 16. A detection sleeve 17 is horizontally and rotatably inserted through the center of the mounting block 13. The inner surface of the detection sleeve 17 is provided with an internal spline that matches the external spline structure on the surface of the spline shaft fork. The adjusting plate 2 is horizontally arranged directly below the placement platform 1. Electric push rods 21 are vertically arranged at both ends of its upper surface and are limit-connected to the placement platform 1 through the electric push rods 21. And the electric push rods 21 are electrically connected to the controller 12 through wires. A connecting block 22 is fixedly provided at the middle position of the upper surface of the adjusting plate 2. A thread groove 23 that matches the structure of the screw 16 is provided at the center of the upper surface of the connecting block 22.

[0017] The upper end of the detection rod 15 is a semi-circular structure. Using this structure, the smoothness of the detection rod 15 when penetrating into the ear hole of the spline shaft fork from bottom to top can be increased. The diameter of the screw 16 is smaller than the diameter of the detection rod 15. A detection label placement groove 18 is fixedly provided on the left side of the front end surface of the placement platform 1. The detection label placement groove 18 can be used to facilitate the storage of detection labels.

[0018] When the utility model is in use, first, by utilizing the cooperation between the internal spline on the inner surface of the detection sleeve 17 and the external spline on the surface of the spline shaft fork, the spline shaft fork to be detected is horizontally and slidably placed inside the detection sleeve 17. At this time, by means of the sliding socket connection between the detection sleeve 17 and the spline shaft fork, while the overall limit placement of the spline shaft fork can be realized, the size of the external spline on the surface of the spline shaft fork can also be detected by observing the connection state between the internal spline on the inner surface of the detection sleeve 17 and the external spline on the surface of the spline shaft fork to determine whether it is qualified. After that, by utilizing the rotational socket connection between the detection sleeve 17 and the mounting block 13, the detection sleeve 17 and the spline shaft fork to be detected can be rotationally adjusted by an external force, so that the ear holes of the spline shaft fork and the detection rod 15 are in the same vertical plane. At the same time, through the rotational adjustment, multi-angle inspection of the surface of the spline shaft fork can also be realized; finally, after the ear holes of the spline shaft fork and the detection rod 15 are in the same vertical plane through the rotational adjustment, the controller 12 is used to control the electric push rod 21 to contract, so that through the contraction of the electric push rod 21, the adjusting plate 2, the connecting block 22 and the detection rod 15 are driven to move in the vertical direction. At this time, as the detection rod 15 moves in the vertical direction, the size and symmetry of the ear holes can be judged by the connection state between the detection rod 15 and the ear holes on both sides of the spline shaft fork to be detected (if the detection rod 15 can smoothly pass through the two ear holes in sequence, it indicates that the size and symmetry of the ear holes on both sides of the spline shaft fork are qualified; if the detection rod 15 cannot pass through the two ear holes, or cannot smoothly pass through the upper ear hole after passing through the lower ear hole, it indicates that the size and symmetry of the ear holes on both sides of the spline shaft fork are unqualified); at the same time, by utilizing the threaded connection between the threaded groove 23 and the screw rod 16, the detachable installation between the detection rod 15 and the adjusting plate 2 can be realized. With this structure, when the detection rod 15 is bent and deformed due to wear or collision during long-term use, the convenience of its replacement operation can be increased; generally, the utility model has the advantages of high detection efficiency, good effect, and convenient operation and use.
