[0033] In this embodiment, the fixture 2 adopts the internal expansion fixture 2 in the prior art. Its structure and the principle of how to clamp the workpiece will not be described in detail. As other solutions, other types of fixture 2 can also be used, and there is no specific limitation on this.

[0034] The feeding mechanism 3 is used to supply the workpiece to be inspected. Specifically, the feeding mechanism 3 includes a vibratory plate 31 and a linear vibrator 32. In this embodiment, the linear vibrator 32 is arranged in a horizontal direction. The discharge end of the vibratory plate 31 is connected to the feed end of the linear vibrator 32. As the vibratory plate 31 continues to work, the workpiece to be inspected vibrates to the discharge end of the vibratory plate 31, then enters the feed end of the linear vibrator 32, and finally is conveyed to the discharge end of the linear vibrator 32, and finally output from the discharge end of the linear vibrator 32.

[0035] The transfer mechanism 4 is used to receive the workpiece to be inspected supplied by the feeding mechanism 3 and bring it close to the feeding mechanism 5. Specifically, the transfer mechanism 4 includes a support base 41, a transfer base 42, a baffle 43, a lifting component 44, a lifting block 45, and a drive component 46. The transfer base 42 is slidably mounted on the support base 41 through a slider and a slide rail on the support base 41. The baffle 43 is installed on one side of the transfer base 42. The drive component 46 is installed on the support base 41 and is used to drive the transfer base 42 to slide, so that the transfer base 42 is connected to the discharge end of the linear vibrator 32 or the baffle 43 blocks the discharge end of the linear vibrator 32. In this embodiment, the drive component 46 is preferably a cylinder, but an electric cylinder or a hydraulic cylinder can also be used. The drive component 46 drives longitudinally.

[0036] It should be noted that the middle transfer seat 42 slides under the driving action of the driving member one 46, and with the sliding of the middle transfer seat 42, when the middle transfer seat 42 is opposite to the discharging end of the linear vibrator 32, the workpiece to be detected enters the middle transfer seat 42 from the discharging end of the linear vibrator 32 under the action of the linear vibrator 32, and vice versa, when the baffle 43 is opposite to the discharging end of the linear vibrator 32, the discharging end of the linear vibrator 32 is blocked by the baffle 43, so that the workpiece to be detected cannot continue to be output from the discharging end of the linear vibrator 32.

[0037] It should be noted that since the middle transfer seat 42 can only accommodate a single workpiece, after the middle transfer seat 42 receives the workpiece, the middle transfer seat 42 slides to block the workpiece from being output from the discharging end of the linear vibrator 32, so as to realize accurate control of the workpiece feeding and quantity.

[0038] The jacking member 44 is installed on the middle transfer seat 42, and in the embodiment, the jacking member 44 is preferably a pneumatic cylinder, and can also be an electric cylinder or an oil cylinder.

It should be noted that in the normal state, the upper surface of the jacking block 45 is flush with the surface of the middle transfer seat 42, and the workpiece to be detected entering the middle transfer seat 42 stays on the upper surface of the jacking block 45, and with the jacking member 44 driving the jacking block 45 to move, the jacking block 45 supports and drives the workpiece to be detected to move.

The output end of the driving piece three 54 is connected with the base 51. The driving piece three 54 is used to drive the base 51 to slide, so that one of the clamping pieces 55 moves back and forth between the transfer seat 42 and the clamp 2, and the other clamping piece 55 moves back and forth between the clamp 2 and the blanking mechanism 7. In this embodiment, the driving piece two 53 and the driving piece three 54 are preferably cylinders, and can also be electric cylinders or oil cylinders. The driving piece two 53 drives in the vertical direction, and the driving piece three 54 drives in the longitudinal direction.

[0042] The sliding of the mounting frame 52 and the sliding of the base 51 driving the mounting frame 52 are both used to realize the movement of the two clamping pieces 55, so as to change the positions of the two clamping pieces 55, realize the movement of the workpiece to be detected from the transfer seat 42 to the clamp 2 and back by the two clamping pieces 55 respectively, and realize the movement of the workpiece detected on the clamp 2 to the blanking mechanism 7 and back by the two clamping pieces 55 respectively.

The rotary driving source 64 is preferably a motor, and can also be other driving sources with rotary function. The output end of the rotary driving source 64 is connected with the detection piece 65. The rotary driving source 64 is used to drive the detection piece 65 to rotate.

[0044] The driving piece four 63 is installed on the support frame 61. The output end of the driving piece four 63 is connected with the mounting seat 62. The driving piece four 63 is used to drive the mounting seat 62 to slide, so that the rotary driving source 64 and the detection piece 65 move close to or away from the workpiece on the clamp 2. In this embodiment, the driving piece four 63 is a cylinder. As other solutions, an electric cylinder or an oil cylinder can also be used. The driving piece four 63 drives in the vertical direction. The mounting seat 62 is driven to slide by the driving piece four 63, so as to meet the stroke requirement of the rotary driving source 64 and the detection piece 65 during detection.

[0045] It should be noted that the detection piece 65 adopts a go gauge or a stop gauge, when the detection piece 65 adopts the go gauge, the go gauge is driven to rotate by the rotary driving source 64, so that the go gauge is threadedly connected with the thread structure of the workpiece, if the go gauge can be smoothly and completely connected with the thread of the workpiece without obstruction or jamming phenomenon, it indicates that the thread structure of the workpiece is qualified, otherwise it indicates that the thread structure of the workpiece is unqualified; while the detection piece 65 adopts the stop gauge, the stop gauge is driven to rotate by the rotary driving source 64, so that the stop gauge is threadedly connected with the thread structure of the workpiece, if the stop gauge can be smoothly and completely connected with the thread of the workpiece without obstruction or jamming phenomenon, it indicates that the thread structure of the workpiece is unqualified, otherwise it indicates that the thread structure of the workpiece is qualified, the thread structure can be external thread or internal thread, which is applicable.

[0046] The rotary driving source 64 and the driving piece four 63 are electrically connected with the controller (not shown in the figure) of the detection machine, it should be noted that the controller can judge whether the thread structure of the workpiece is qualified through the torsion of the rotary driving source 64 or the stroke parameter of the driving piece four 63.
