The workstations include a rotating workstation 4, a hole position detection workstation 5, a small thread hole detection workstation 6, and a large thread hole detection workstation 7.

[0042] The hole position detection station is equipped with a position detection gauge 51, a first lifting mechanism 52 and a pressing mechanism 53. The first lifting mechanism lifts the product, and the pressing mechanism presses the product down to see if the hole to be inspected can be inserted into the position detection gauge.

[0043] The product is moved between multiple workstations using a handling mechanism;

[0044] like Figure 3 and Figure 4 As shown, the small thread hole detection station and the large thread hole detection station are equipped with a thread hole detection device 1 and a second lifting mechanism 8, which holds the product in place. The thread hole detection device 1 includes a mounting frame 11, a mounting base 12, a small thread hole detection mechanism 13, a large thread hole detection mechanism 14, and a mounting base lifting drive mechanism 15. The mounting base lifting drive mechanism is mounted on the mounting frame, and the small thread hole detection mechanism and the large thread hole detection mechanism are both mounted on the mounting base. The mounting base is lifted and lowered by the mounting base lifting drive mechanism.

[0045] The small thread hole detection mechanism 13 includes a first drive motor 131 and a small thread detection component 132; the large thread hole detection mechanism 14 includes a second drive motor 141, multiple connectors (not shown in the figure) and multiple large thread detection components 142, the upper end of the connector is connected to the power output end of the second drive motor, and the lower end of the connector is connected to the upper end of the large thread detection component.

[0046] like Figure 1The rotary station is also provided with a loading station 9 upstream of it. The loading station is provided with a pushing mechanism 91. The pushing mechanism 91 includes a pushing drive cylinder 911 and a pushing plate 912. The pushing plate is fixed to the power output end of the pushing drive cylinder. The pushing plate is driven by the pushing drive cylinder to push the product to the rotary station.

[0047] In this embodiment, as Figure 1 Hehe Figure 2 As shown, the auxiliary positioning mechanism 41 includes an auxiliary positioning drive cylinder 411 and a positioning head 412, wherein the positioning head is fixed to the power output end of the auxiliary positioning drive cylinder.

[0048] like Figure 3 As shown, the rotary drive mechanism 42 includes a rotary drive motor 421 and a rotary head 422. The rotary rod is fixed to the power output end of the rotary drive motor, and the upper end of the rotary head can abut against the product.

[0049] In this embodiment, as Figure 10 As shown, the first lifting mechanism 52 includes a first lifting drive cylinder 521 and a lifting head 522, wherein the lifting head is fixed to the power output end of the first lifting drive cylinder;

[0050] The pressing mechanism 53 includes a pressing drive cylinder 531 and a pressing head 532, wherein the pressing head is fixed to the power output end of the pressing drive cylinder.

[0051] like Figures 4 to 7 As shown, in this embodiment, both the small thread detection assembly and the large thread detection assembly include an upper shell 1321, a lower shell 1322, a connecting rod 1323, a connecting sleeve 1324, and a thread plug gauge 1325. The upper shell and the lower shell are assembled together. The upper end of the connecting rod is connected to the power output end of the first drive motor or the second drive motor. The lower end of the connecting rod is fixed together with the upper end of the connecting sleeve. The thread plug gauge is fixedly connected inside the connecting sleeve. A gap is left between the upper end of the connecting sleeve and the inner wall of the lower shell.

[0052] In this embodiment, the inner diameter of the upper end of the lower shell is 0.6-1.4 mm larger than the outer diameter of the mounting platform. That is, the width of the gap is 0.3-0.7 mm. This dimension is reasonably designed, taking into account the possible positional deviation of the large threaded hole on the wheel hub bearing.

[0053] During the machining process, the large threaded hole on the wheel hub bearing will inevitably have a positional deviation. Making the connecting sleeve and the thread plug gauge so that they can float horizontally within the lower shell by a certain distance can solve the above problem. As long as it is within a certain offset error range, the thread plug gauge can be smoothly inserted into the large or small threaded hole for inspection.

[0054] like Figures 4 to 7 As shown in the figure, in this embodiment, the connecting component is a universal coupling (such as the WSP-GA telescopic universal joint coupling produced by Shanghai Songming Transmission Machinery Co., Ltd., but not limited to this). A large gear 143 is installed at the end of the main shaft of the second drive motor, and multiple small gears 144 are provided around the large gear. The center of the small gears is connected to the upper end of the universal coupling, and the large gear and the small gears mesh. The connecting component can also adopt other structures, such as a straight rod, which can transmit the power of the second drive motor to the large thread detection component to drive the thread plug gauge to rotate. As shown in Figure 1, the upper end of the universal coupling is connected at position A, and the lower end is connected at position B.

[0055] In this embodiment, bearings 1326 are installed between the upper and lower ends of the connecting rod and the upper shell; a bearing is also provided between the connecting sleeve and the lower shell. This ensures smooth movement.

[0056] like Figures 4 to 7 As shown, in this embodiment, the upper end of the connecting sleeve is provided with a hanging platform 13241, which is hung on the step of the constricted opening of the lower shell; a gasket 1327 is provided directly between the hanging platform and the step.

[0057] like Figures 4 to 7 As shown, in this embodiment, the mounting base lifting drive mechanism 15 includes a mounting base lifting drive cylinder 151 and a push rod 152. The upper end of the push rod is fixed to the power output end of the mounting base lifting drive cylinder, and the lower end of the push rod is fixed to the mounting base.

[0058] like Figure 8 As shown, in this embodiment, the second lifting mechanism 8 includes a second lifting drive cylinder 81 and a lifting plate 82. The lifting plate is provided with a plurality of detection sensors 83 for detecting whether the thread plug gauge is screwed in properly.

[0059] In this embodiment, the position detection gauge consists of multiple guide posts.

[0060] In this embodiment, as Figure 9 As shown, the conveying mechanism 3 includes a fixed side clamping plate 31, a movable side clamping plate 32, a clamping and translational drive cylinder 33, and a clamping drive cylinder 34. The inner surfaces of the fixed side clamping plate and the movable side clamping plate are provided with multiple grippers 311 in opposite positions. The fixed side clamping plate is fixed at the clamping drive cylinder, and the movable side clamping plate is installed at the power output end of the clamping drive cylinder. The clamping drive cylinder drives the movable side clamping plate to move closer to or away from the fixed side clamping plate. The clamping and translational drive cylinder drives the fixed side clamping plate and the movable side clamping plate to translate simultaneously along the product movement direction.

[0061] In this embodiment, the conveying mechanism will realize the step-by-step movement of the product, that is, move the product from the rotating station to the hole position detection station; at the same time, it will move the product on the hole position detection station to the small thread detection station, move the product on the small thread detection station to the large thread detection station, and move the product on the large thread detection station to the unloading station.

[0062] The workstation also includes a material unloading station 20, which is located downstream of the large thread hole detection station. The material unloading station is connected to an inclined material unloading chute 201, and the product automatically flows down after being transported to the material unloading station.

[0063] The working principle and process of this utility model:

[0064] Products, such as wheel hub bearings, have one small threaded hole and five large threaded holes. The wheel hub bearing to be inspected is placed at the loading station, and the pushing mechanism pushes the product to the rotating station. The auxiliary positioning mechanism 41 presses down to position it, and the rotating drive mechanism 42 drives the product to rotate to the required position (which can be sensed by a sensor to make the large and small threaded holes on the product correspond to the subsequent inspection gauge, etc.). Then, the conveying mechanism moves the product to the hole position inspection station, the first lifting mechanism lifts it up, and the conveying mechanism places the product on the lifting head of the first lifting mechanism. Then, the pressing mechanism presses down on the product. If the product can be pressed into the position inspection gauge, it means that the position of the hole in the product is qualified. Next, the transport mechanism moves the product to the small thread hole inspection position. The mounting seat lifting drive cylinder drives the mounting seat to descend into place. Then, the first drive motor drives the small thread inspection component to position and inspect the small thread hole. At the same time, the second lifting mechanism drives the inspection sensor to rise and check whether the thread plug gauge is screwed in properly. Then, the transport mechanism moves the wheel hub bearing to directly below the large thread hole inspection station. Then, the second drive motor drives multiple large thread inspection components to position and inspect the large thread hole. At the same time, the inspection sensor checks whether the thread plug gauge is screwed in properly. After that, the transport mechanism moves the product to the unloading station, completing the inspection of one product. The above process can be repeated.

[0065] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
