Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-5 , an eccentric detection device for motor housing processing, including a machine table 1. A driving motor 3 is provided on one side of the machine table 1 through a mounting seat 2. The output end of the driving motor 3 is connected to a driving rod 4. A pair of V-shaped connecting rods 11 are provided in the middle of the driving rod 4. Each pair of V-shaped connecting rods 11 are connected through a connecting seat 12, and a regulating screw 10 is connected to the middle of the connecting seat 12. One end of the regulating screw 10 is rotatably installed in a clamping groove 9 opened on one side of the driving rod 4. A dial indicator 6 is clamped and installed in the clamping groove 9. One end of the dial indicator 6 is fixedly installed on a slider 8;

[0023] Furthermore, a pair of mounting grooves 41 are opened on the outer side of the driving rod 4. A locking block 5 is installed in the mounting grooves 41 in a limited sliding manner. The middle of the locking block 5 is connected to the V-shaped connecting rod 11 through a connecting block 51.

[0024] Furthermore, a clamping groove 9 is opened at one end of the driving rod 4. A threaded hole is provided inside the clamping groove 9. A regulating screw 10 is screwed into the threaded hole. One end of the regulating screw 10 extends into a cavity opened inside the driving rod 4 and is rotatably installed on one side of the inner wall of the cavity.

[0025] Furthermore, two threads in opposite directions are provided on one side of the regulating screw 10, namely a right-handed thread 13 and a left-handed thread 131. A connecting seat 12 is screwed onto both the right-handed thread 13 and the left-handed thread 131. V-shaped connecting rods 11 are connected to both the upper and lower ends of the connecting seat 12.

[0026] Furthermore, both ends of the V-shaped connecting rod 11 are rotatably connected to the connecting seat 12 through hinges, and a connecting block 51 is installed in the middle of the V-shaped connecting rod 11.

[0027] Furthermore, a sliding groove 7 is opened in the middle of the machine table 1. A slider 8 is installed in the sliding groove 7 in a sliding manner. A dial indicator 6 is installed on one side of the slider 8 through a mounting bracket 82. The measuring probe of the dial indicator 6 faces upward, and a roller 61 is rotatably installed at the tip of its probe.

[0028] Furthermore, a bearing member 62 is provided on one side of the dial indicator 6. The other end of the bearing member 62 is connected to a clamping cylinder 63. The clamping cylinder 63 is fitted with the clamping groove 9.

[0029] In this embodiment, the motor housing to be detected is clamped into the locking block 5, and the adjusting screw 10 provided in the middle of the driving rod 4 is rotated. The adjusting screw 10 rotates and drives the V-shaped connecting rods 11 to move towards each other and contract through thread rotation. During the contraction process, the V-shaped connecting rods arch and drive the locking block 5 to rise, thereby locking the workpiece clamped to the locking block 5.

[0030] Then, the slider 8 is clamped into the chute 7 provided in the middle of the machine table 1 and locked by the corresponding fastener 81 to prevent its displacement. At the same time, the dial indicator 6 assembly provided on the slider 8 is clamped to the clamping groove 9 on the driving rod 4 through the clamping cylinder 63. At this time, the driving motor 3 is operated to drive the driving rod 4 to rotate. During the rotation process, due to the setting of the bearing member 62, the dial indicator 6 remains stationary, and its clamping cylinder 63 rotates with the rotation of the driving rod 4.

[0031] During the rotation of the driving rod 4, the workpiece rotates, and a roller 61 is provided at the probe part of the dial indicator 6. The roller 61 makes rolling contact with the inner wall of the workpiece, and then the deviation value generated by the rotation is displayed through the dial indicator 6. At this time, the operator can observe the scale of the dial indicator 6.

[0032] Among them, in the actual use process, the right-handed thread 13 and the left-handed thread 131 are provided on the adjusting screw 10, and connecting seats 12 are connected to both the right-handed thread 13 and the left-handed thread 131. During the rotation of the adjusting screw 10, under the rotation action of the opposite threads, the connecting seats 12 at both ends approach each other. At this time, under the influence of the movement of the connecting seat 12, the internal angle of the V-shaped connecting rod 11 connected to the connecting seat 12 shrinks, that is, it gradually closes. At this time, the V-shaped connecting rod 11 slowly arches and drives the locking block 5 connected thereto to move through the connecting block 51. At this time, the locking block 5 moves in the installation groove 41 provided on the driving rod 4.

[0033] Among them, it should be noted that the V-shaped connecting rod 11 includes a pair of rod bodies that are rotatably connected to each other. The rod bodies are connected by hinges to achieve the mutual rotation function, and both ends of the rod bodies are rotatably connected to the connecting seat 12 respectively.

[0034] In the present utility model, the motor housing to be detected is clamped into the locking block 5, and the locking block 5 is driven to lock the workpiece by rotating the adjusting screw 10. At the same time, the dial indicator assembly is connected to the driving rod 4, and the driving motor 3 is started to drive the workpiece to rotate. During the rotation process, the probe part of the dial indicator contacts the inner wall of the workpiece through the roller 61, and the deviation value is displayed through the dial indicator 6. The detection process is not only convenient but also the detection data is stable. Compared with manual detection, this mechanism has high detection efficiency, accurate detection data, and convenient operation.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
