[0045] Since the plane in which the longitudinal floating assembly 2 is floatingly adjusted in the longitudinal direction is perpendicular to the plane in which the transverse floating assembly 3 is floatingly adjusted in the transverse direction, the position of the screw thread detection tool in the horizontal direction can be adjusted by the longitudinal floating assembly 2 and the transverse floating assembly 3; when the screw thread detection tool 4 detects the screw thread hole of the product, if there is a slight deviation between the central axis of the screw thread detection tool 4 in the vertical direction and the central axis of the screw thread hole of the product in the vertical direction, that is, there is a deviation in the relative position in the horizontal direction, the screw thread detection tool can be moved by the longitudinal floating assembly 2 and the transverse floating assembly 3, so that the screw thread detection tool 4 is adaptively floatingly adjusted, so that the central axis of the screw thread detection tool 4 in the vertical direction is coaxial with the central axis of the screw thread hole of the product in the vertical direction, so that the screw thread detection tool 4 can be effectively inserted into the screw thread hole of the product and the screw thread hole of the product is detected.

[0047] Since the first balance link 23 and the second balance link 24 are pivotally connected in parallel between the first balance block 21 and the second balance block 22, the first balance link 23 and the second balance link 24 can swing in parallel relative to the first balance block 21, thereby driving the second balance block 22 to move obliquely upward, while the second balance block 22 moves in parallel relative to the first balance block 21. Since the third balance link 33 and the fourth balance link 34 are pivotally connected in parallel between the third balance block 31 and the fourth balance block 32, the third balance link 33 and the fourth balance link 34 can swing in parallel relative to the third balance block 31, thereby driving the fourth balance block 32 to move obliquely upward, while the fourth balance block 32 moves in parallel relative to the third balance block 31.

[0050] Referring to Figure 1 and Figure 3In an embodiment, the longitudinal floating assembly 2 further comprises a first elastic reset member 25 abutting between the first counterweight 21 and the second counterweight 22 in the up-down direction, and the first elastic reset member 25 is used to drive the second counterweight 22 to move back. When the first balance link 23 and the second balance link 24 swing in parallel to drive the second counterweight 22 to move in the oblique upward direction, the second counterweight 22 presses the first elastic reset member 25. In addition, after the thread detection is completed, the second counterweight 22 can also move back under the action of its own gravity and the elastic restoring force of the first elastic reset member 25.

[0051] Referring to Figure 1 and Figure 3 In an embodiment, the transverse floating assembly 3 further comprises a second elastic reset member 35 abutting between the third counterweight 31 and the fourth counterweight 32 in the up-down direction, and the second elastic reset member 35 is used to drive the fourth counterweight 32 to move back.

[0053] When the threaded detection tool 4 detects the threaded hole of the product, if there is an included angle between the threaded detection tool 4 and the threaded hole of the product, the threaded detection tool 4 can be rotated through the rotation of the lower swing sleeve 63 relative to the angle swing shaft 62 and the upper swing sleeve 61, so that the direction of the threaded detection tool 4 is parallel to the direction of the threaded hole of the product, that is, the central axis of the threaded detection tool 4 in the up-down direction is parallel to the central axis of the threaded hole of the product in the up-down direction, so that there is no included angle between the threaded detection tool 4 and the threaded hole of the product, thereby enabling the threaded detection tool 4 to be effectively inserted into the threaded hole of the product and to detect the threaded hole of the product. The lower swing sleeve 63 can rotate relative to the angle swing shaft 62 and the upper swing sleeve 61 in two perpendicular plane directions. In one of the plane directions, when the lower swing sleeve 63 rotates relative to the angle swing shaft 62 and the upper swing sleeve 61, the lower swing sleeve 63 and the sliding groove 631 of the lower swing sleeve 63 slide relative to each other, and the direction of the sliding groove 631 of the lower swing sleeve 63 and the direction of the movable swing pin 64 are changed from perpendicular to oblique intersection, and the included angle between the two is changed from a right angle to an acute angle. In the other plane direction, when the lower swing sleeve 63 rotates relative to the angle swing shaft 62 and the upper swing sleeve 61, the lower swing sleeve 63 rotates around the movable swing pin 64 as the center, and the direction of the sliding groove 631 of the lower swing sleeve 63 and the direction of the movable swing pin 64 remain perpendicular.

[0065] In combination with Figures 1 to 10 The specific working principle of the thread detection device 300 of the present application is as follows:

[0066] The feeding and distributing mechanism 305 can distribute the provided products, so that the feeding manipulator 306 carries the distributed products to the positioning jig 304 of the turntable 303, clamps and positions the products through the positioning jig 304, and drives the turntable 303 to rotate through the rotating drive mechanism 302 to drive the positioning jig 304 with the products to rotate to the next station, i.e. the position corresponding to the first thread detection module 200. The moving drive assembly 201 of the thread detection module 200 is used to drive the thread detection floating mechanism 100 to move and rotate, so that the thread detection tool 4 detects the thread gauge of the thread hole of the product. Then, the turntable 303 is driven to rotate through the rotating drive mechanism 302 to drive the positioning jig 304 with the products to rotate to the next station, i.e. the position corresponding to the second thread detection module 200. The moving drive assembly 201 of the thread detection module 200 is used to drive the thread detection floating mechanism 100 to move and rotate, so that the thread detection tool 4 detects the thread gauge of the thread hole of the product.

[0067] In the process of thread detection, if the center axis of the thread detection tool 4 in the up-down direction has a slight deviation from the center axis of the thread hole of the product in the up-down direction, the second balance block 22 of the longitudinal floating assembly 2 and the fourth balance block 32 of the transverse floating assembly 3 can drive the thread detection tool 4 to move, so that the thread detection tool 4 can be adaptively adjusted in position, thereby making the center axis of the thread detection tool 4 in the up-down direction coaxial with the center axis of the thread hole of the product in the up-down direction, so as to ensure that the thread detection tool 4 can be effectively inserted into the thread hole of the product and detect the thread hole of the product. If there is an included angle between the thread detection tool 4 and the thread hole of the product, the lower swing sleeve 63 can be rotated relative to the angle swing shaft 62 and the upper swing sleeve 61, thereby driving the thread detection tool 4 to rotate, so that the direction of the thread detection tool 4 is parallel to the direction of the thread hole of the product, that is, the center axis of the thread detection tool 4 in the up-down direction is parallel to the center axis of the thread hole of the product in the up-down direction, so that there is no included angle between the thread detection tool 4 and the thread hole of the product, thereby making the thread detection tool 4 can be effectively inserted into the thread hole of the product and detect the thread hole of the product.

[0068] After the product completes all thread detection, the rotating disc 303 is driven to rotate by the rotating driving mechanism 302, so as to drive the positioning jig 304 loaded with the product to rotate to the next station, that is, the position corresponding to the unloading mechanism 307.

In the threaded detection floating mechanism 100, the lower swing sleeve 63 of the angle floating adjustment assembly 6 can be rotated relative to the angle swing shaft 62 and the upper swing sleeve 61, so as to drive the threaded detection tool 4 to rotate, so that the direction where the threaded detection tool 4 is located is parallel to the direction where the threaded hole of the product is located, that is, the central axis of the threaded detection tool 4 in the up-down direction is parallel to the central axis of the threaded hole of the product in the up-down direction, so that there is no included angle between the threaded detection tool 4 and the threaded hole of the product, so that the threaded detection tool 4 can be effectively inserted into the threaded hole of the product and the threaded hole of the product is threaded detected.
