[0038] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0039] EMBODIMENT

[0040] In order to solve the problem that the existing rotating shaft locking swing machine cannot detect whether the positioning PIN 65 on the cam 62 of the rotating shaft 60 (refer to Figure 1 ) is embedded in the PIN hole 66, which may cause the risk of breaking of the positioning PIN during use of the rotating shaft, as shown in Figure 2 , the present application discloses a lock nut swing machine with product quality detection structure, which comprises a test machine 10, a rack 20, a swing test mechanism 30, a lock nut mechanism 40 and a height detection mechanism 50; the rack 20 is arranged above the test machine 10;

[0041] The swing test mechanism 30 comprises a swing driving member 31 arranged inside the test machine 10, a product carrier 32 connected with the swing driving member 31 above the test machine 10, a YZ-axis driving slide table 33 arranged on the test machine 10 between the rack 20 and the product carrier 32, and a rotating chuck 34 arranged on the YZ-axis driving slide table 33;

[0042] The lock nut mechanism 40 comprises an X-axis fine adjustment driving slide table 41 arranged above the rack 20, a Z-axis driving slide table 42 arranged on the X-axis fine adjustment driving slide table 41, and an electric wrench 43 arranged on the Z-axis driving slide table 42;

[0043] The height detection mechanism 50 comprises a Z-axis driving member 51 arranged on the test table at one side of the product carrier 32, an X-axis driving member 52 arranged on the Z-axis driving member 51, a first contact sensor 53 arranged on the X-axis driving member 52, a “]” shaped member 54 arranged on the test table between the product carrier 32 and the Z-axis driving member 51, and a second contact sensor 55 arranged inside the “]” shaped member 54 and in contact with the top wall inside the “]” shaped member 54.

[0044] Before the whole machine is operated, the operator first adjusts the position of the Z-axis driving slide table 42 through the X-axis fine adjustment driving slide table 41 so that the electric wrench 43 corresponds to the product carrier 32;

[0045] In the specific implementation process, after the operator vertically assembles the shaft to be detected on the product carrier 32, the operator controls the Z-axis driving slide table 42 to lower the electric wrench 43, and controls the electric wrench 43 to work to lock the nut 64 after the electric wrench 43 is lowered to the position (after the nut is locked, the Z-axis driving slide table 42 drives the electric wrench 43 to reset), then the X-axis driving member 52 drives the first contact sensor 53 to extend, when the first contact sensor 53 is located directly above the nut, the Z-axis driving member 51 drives the X-axis driving member 52 to lower so that the contact of the first contact sensor 53 contacts the nut, and the detection value obtained by the first contact sensor is set as T1, at the same time, the actual value detected by the second contact sensor is set as T2 plus the difference from the reference surface;

[0046] If the value T1-T2 detected by the first contact sensor 53 is within the set tolerance, it means that the positioning PIN of the shaft cam is inserted into the PIN hole;

[0047] If the value T1-T2 detected by the first contact sensor 53 is not within the set tolerance, it means that the positioning PIN of the shaft cam is not inserted into the PIN hole;

[0048] After the above work is completed, the X-axis driving member 52 drives the first contact sensor 53 to reset, and the Z-axis driving member 51 drives the Z-axis driving member 51 to reset.

[0049] If the positioning PIN of the rotating shaft cam has been inserted into the PIN hole, the YZ axis driving sliding table 33 drives the rotating chuck 34 to extend and drop so as to insert the fixed support of the rotating shaft into the rotating chuck 34, and when the swing driving member 31 drives the product carrier 32 to rotate, the fixed support 63 will swing and rotate with the mandrel 61 of the rotating shaft.

[0050] It is optional for the present application that the swing driving member 31 is a motor, and under the driving of the motor, the product carrier 32 of the present application will perform a rotating motion, and in actual use, if other swing driving members 31 can replace the motor to make the product carrier 32 realize a swing motion, the person skilled in the art can select adaptively.

[0051] Reference Figure 1 and Figure 5 As shown in the figure, the product carrier 32 of the present application is internally provided with a slot 321 for inserting the rotating shaft, and in specific implementation, the operator will insert the mandrel of the rotating shaft into the slot 321.

[0053] Reference Figure 4As shown and based on the above structure of the YZ axis driving slide table 33, the rotating chuck 34 of the application comprises a first guide rail 341, a carrier block 342, a swing block 343, a T-shaped chuck 344, two bending pieces 347 and two springs 348, the first guide rail 341 is arranged on the sliding block of the Y-axis pneumatic slide table 334 along the Y-axis direction, the carrier block 342 is slidingly arranged on the first guide rail 341, an axle 345 is arranged above the carrier block 342, the swing block 343 is arranged above the carrier block 342 and has a bearing 346 arranged inside to connect the axle 345, the T-shaped chuck 344 is arranged on the swing block 343, and a clamping groove 3441 is arranged in the vertical part of the T-shaped chuck 344 and faces the product carrier 32, the two bending pieces 347 are arranged on the two sides of the Y-axis pneumatic slide table 334 respectively, and the two springs 348 are connected between the two bending pieces 347 and the carrier block 342. Under the driving of the Y-axis pneumatic slide table 334, the rotating chuck 34 based on the above structure can be used for swing test of the rotating shaft. Under the driving of the Y-axis pneumatic slide table 334, the fixed support of the rotating shaft will be inserted into the clamping groove 3441 of the T-shaped chuck 344. When the swing driving piece 31 drives the product carrier 32 to rotate and swing, the T-shaped chuck 344 will rotate and elastically stretch and contract in the Y-axis direction.

[0054] Specifically, the X-axis fine adjustment driving slide table 41 of the application is a lead screw slide table, and a fine adjustment knob 411 is arranged outside the lead screw slide table and connected with the lead screw of the lead screw slide table. When the operator operates the fine adjustment knob to rotate, the lead screw slide table can drive the Z-axis driving slide table 42 to adjust in the X-axis direction.
