Specific implementation manners
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0025] Referring to Figures 1-7 , a placement rack for detecting an automobile drive shaft assembly, including a bottom plate 1. A plurality of pulleys 2 are fixedly installed on the bottom wall of the bottom plate 1. A support platform 4 is fixedly installed on the upper end surface of the bottom plate 1 through a lifting mechanism. The lifting mechanism includes a cylinder 3 fixedly installed on the upper end surface of the bottom plate 1. The telescopic end of the cylinder 3 is fixedly connected to the bottom wall of the support platform 4. A plurality of stabilizing rods 5 are fixedly installed on the upper end surface of the bottom plate 1. Each stabilizing rod 5 slidably penetrates through the support platform 4. A stabilizing plate 6 is fixedly installed on the outer wall of each stabilizing rod 5. A first screw 7 is rotatably installed on the upper end surface of the support platform 4 through a moving groove. The first screw 7 is a double-headed screw. A motor 8 connected to the first screw 7 is fixedly installed on the outer wall of the support platform 4. Two moving blocks 10 are threadedly installed on the outer wall of the first screw 7. A limiting rod 9 is fixedly installed inside the moving groove. The limiting rod 9 slidably penetrates through the two moving blocks 10. The limiting rod 9 can limit the two moving blocks 10, so that the two moving blocks 10 can only axially move along the outer wall of the first screw 7.
[0026] Support frames 11 are fixedly installed on the upper end faces of both of the two moving blocks 10. First clamping plates 13 are fixedly installed on the inner bottom walls of the two support frames 11 through support mechanisms. The support mechanisms include two support blocks 12 fixedly installed on the inner bottom walls of the support frames 11. The ends of the two support blocks 12 are fixedly connected to the outer walls of the first clamping plates 13. Second screws 14 are rotatably installed through the upper end faces of the two support frames 11 in a threaded manner. Rocking wheels 15 are fixedly installed on the outer walls of the two second screws 14. Second clamping plates 17 are rotationally connected to the ends of the two second screws 14 through connection mechanisms. The connection mechanisms include connection blocks 16 fixedly installed at the ends of the second screws 14. The ends of the connection blocks 16 are rotationally connected to the outer walls of the second clamping plates 17. A plurality of clamping rollers 18 are rotatably installed on the inner walls of the two first clamping plates 13 and the two second clamping plates 17 through installation grooves. Each clamping roller 18 is made of rubber. Rubber has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing the friction force and improving the friction coefficient. Limit plates 19 are fixedly installed on the outer walls of the two second clamping plates 17. Moving openings adapted to the limit plates 19 are formed in the outer walls of the two support frames 11.
[0027] When the present utility model is in use, the bottom plate 1 can be conveniently moved through a plurality of pulleys 2. When placing the transmission shaft, the air cylinder 3 can drive the support platform 4 to move downward so that it is in a lower position. Subsequently, the transmission shaft can be placed between the inner walls of the two first clamping plates 13. Then, the air cylinder 3 can drive the transmission shaft to move up and down through the support platform 4, whereby the transmission shaft can be in a position convenient for detecting it. During this process, the support platform 4 can slide on the outer walls of multiple stabilizing rods 5, thereby increasing the stability of the up and down movement of the support platform 4. Before detecting the transmission shaft, the rocking wheel 15 can be rotated to drive the second screw 14 to rotate. When the second screw 14 rotates, it can drive the second clamping plate 17 to move through the cooperation of the connection block 16. At this time, the second clamping plate 17 can drive the limit plate 19 to move in the moving opening. Through the cooperation of the limit plate 19 and the moving opening, the second clamping plate 17 can only move vertically downward;
[0028] Driven by the second screw 14, the second clamping plate 17 can move downward and approach the first clamping plate 13, and the transmission shaft can be clamped by a plurality of rotatably installed clamping rollers 18. And during the detection of the transmission shaft, the transmission shaft can rotate between the first clamping plate 13 and the second clamping plate 17 through the cooperation of a plurality of rotatably installed clamping rollers 18, thereby increasing the convenience during the detection of the transmission shaft. When placing transmission shafts of different lengths, the motor 8 can drive the first screw 7 to rotate. When the first screw 7 rotates, it can drive the two moving blocks 10 to move through the cooperation of the limit rods 9, whereby the two moving blocks 10 can drive the support frames 11 on the same side to move respectively, so that the first clamping plates 13 and the second clamping plates 17 on both sides can place and clamp transmission shafts of different lengths.
[0029] 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, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
