To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
The third driving part, the fourth driving part and the seventh driving part described below may be a driving cylinder or a driving cylinder, or may be other driving members capable of driving other members to move or rotate.
As shown in fig. 1 to 3, the present embodiment discloses a micro worm shaft surface flaw detection mechanism.
Referring to fig. 1, including a picture-capturing means 400, further including,
a holding member 300, wherein the holding rod 310 of the holding member 300 is positioned in the capturing region of the image capturing member 400, and can drive the worm shaft 2 to rotate, so that the image capturing member 400 can capture the image of the outer periphery of the worm shaft 2;
and a material transfer unit 500 which is located on the opposite side of the material holding member 300, and which is capable of transferring the worm shaft 2 to the material holding member 300 and removing the worm shaft 2 from the material transfer unit 500 after completion of the screen capture.
The above is the basic scheme of the present embodiment. The worm shaft 2 is conveyed to the holding member 300 by the conveying assembly 500 and is sleeved on the holding rod 310, and when the holding rod 310 rotates, the worm shaft 2 is driven to rotate together. The worm shaft 2 rotates in the lens capturing area of the image capturing member 400, and the image capturing member 400 photographs and detects the worm shaft 2 and transmits the image to the host for judgment.
Preferably, in order to ensure that the screen capturing member 400 can capture the entire periphery of the worm shaft 2 without any dead angle, the material holding bar 310 is rotated at least 360 degrees, preferably 540 degrees in this embodiment.
Meanwhile, the preferred picture capturing means 400 in the present embodiment is an industrial camera. The industrial camera is a camera device which can be applied to an industrial field, has the requirement of being suitable for industrial complex environment and can stably work for a long time. The industrial camera is a video image acquisition device which can be stably and efficiently applied to an industrial field, can directly store images on a hard disk, has high comparability in resolution, frame rate, requirements on light, exposure mode and the like compared with a common camera, and is mainly provided with a CCD photosensitive chip.
Specifically, in the present embodiment, the material holding member 300 is a spindle box, and the material holding rod 310 is a rotating shaft located on the spindle box; the worm shaft 2 can be sleeved on the material holding rod 310 and rotate together with the material holding rod 310.
Preferably, the material holding rod 310 in this embodiment is arranged in a horizontal direction, and the worm shaft 2 is also sleeved on the material holding rod 310 in the horizontal direction, so that during the rotation process, the worm shaft 2 only needs to overcome the relative movement with the material holding rod 310, and can be ensured to rotate together with the material holding rod 310. The material holding rod 310 arranged in the vertical direction can shake with the material holding rod 310 due to the gravity action in the rotating process, so that the material holding rod 310 is damaged.
In order to solve the problem of relative movement between the holding rod 310 and the worm shaft 2, the holding rod 310 is preferably a tapered rod in this embodiment, and the diameter of the end of the holding rod 310 close to the headstock is larger than the diameter of the end far from the headstock.
When the worm shaft 2 is sleeved on the material holding rod 310, the diameter of the outer end of the material holding rod 310 is smaller than the shaft hole of the worm shaft 2, and the worm shaft 2 can be smoothly sleeved and has a gap with the material holding rod 310. When the worm shaft 2 is pushed into the holding rod 310, the gap between the worm shaft 2 and the holding rod 310 gradually decreases as the diameter of the holding rod 310 gradually increases. When the worm shaft 2 is pushed to the bottom of the holding rod 310, i.e. near one end of the headstock, there is no gap between the worm shaft 2 and the holding rod 310, so as to achieve an interference fit, and a friction force is generated between the shaft hole of the worm shaft 2 and the holding rod 310, so that the worm shaft can be kept relatively stationary during rotation.
In this embodiment, the material transporting assembly 500 includes a rotating frame 510, and the rotating frame 510 includes at least one material transporting hole; the rotating frame 510 can be driven by the third driving part 530 to rotate to the material conveying position, so that the material conveying hole and the material holding rod 310 can be in a coaxial position.

When the material conveying assembly 500 conveys the worm shaft 2 from the previous process, the worm shaft 2 is inserted into the material conveying hole. The rotating frame 510 is rotated to the material conveying position by the third driving part 530, and the material conveying hole and the material holding rod 310 are in the coaxial position. Meanwhile, the feed bar 520 is located at the other side of the rotating frame 510, and is also located at the same axial position as the material conveying hole. The fourth driving part 540 drives the feed rod 520 to move toward the feed hole, and pushes out the worm shaft 2 in the feed hole, so that the worm shaft 2 moves toward one side of the holding rod 310 and is sleeved on the holding rod 310.
Preferably, in this embodiment, a driving sleeve 550 is disposed in the material transporting hole.
Since the thickness of the rotating frame 510 is limited, only a small section of the worm shaft 2 inserted into the rotating frame 510 is caught on the rotating frame 510, and the worm shaft is easily shaken and falls off the rotating frame 510 during the rotation. The driving housing 550 is provided, and the driving housing 550 is provided with a housing hole 551 having an outer diameter size fitting the worm shaft 2, and the worm shaft 2 is inserted into the housing hole 551 to extend the insertion length of the worm shaft 2, so that it can be stably rotated.
When the detection is finished, the worm shaft 2 needs to be withdrawn from the material holding rod 310 for blanking, so that the next worm shaft 2 can be detected, as shown in fig. 3, a material returning member 1 is further provided at the side portion of the material holding rod 310, the material returning member 1 can contact with the end surface of the worm shaft 2 close to the headstock, and is driven by the seventh driving part 1.1 to move along the axis of the material holding rod 310, so that the worm shaft 2 is pushed out from the material holding rod 310.
In the initial state, the end of the ejector member 1 is located outside the bottom of the material holding rod 310, i.e., near the headstock, with the worm shaft 2 in front of the ejector member 1. The spindle box stops rotating, detection is completed, the seventh driving part 1.1 is started to drive the material returning component 1 to move outwards and be away from the spindle box, the material returning component 1 is in contact and abutting contact with the worm shaft 2 in the moving process, and the worm shaft 2 is pushed outwards until the worm shaft 2 is pushed into the sleeve hole 551 of the transmission sleeve 550 on the rotating frame 510. The seventh driving part 1.1 drives the material returning component 1 to reset and return to the bottom of the material holding rod 310.
Preferably, the end of the material returning member 1 is an arc-shaped sleeve portion, which can be sleeved on the outer portion of the material holding rod 310 and is in clearance fit with the material holding rod 310.
Preferably, the inner diameter of the end of the ejector member 1 is smaller than the outer diameter of the worm shaft 2.
In other possible embodiments, the end of the material returning component 1 can be arranged as a sleeve structure and is in clearance fit with the material holding rod 310. At the same time, the inside diameter of the sleeve is smaller than the outside diameter of the worm shaft 2
