The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to fig. 3, an embodiment of the present invention provides a pick-and-place device, which includes a housing 10 and a pick-and-place assembly 20. Specifically, the taking and placing assembly 20 is rotatably disposed in the housing 10, the taking and placing assembly 20 has a driving end and a taking and placing end, the taking and placing end is located outside the housing 10, a protruding portion 21 is disposed on one side of the taking and placing end, and the taking and placing assembly 20 has a working state and an avoiding state. When the taking and placing assembly 20 is in the working state, the protruding portion 21 protrudes to the periphery of the housing 10 to abut against the workpiece 11, so that the workpiece 11 can be taken out from the deep hole by using the taking and placing device, and when the taking and placing assembly 20 is in the avoiding state, the protruding portion 21 is located on the inner side of the housing 10, and at this time, the taking and placing device can be smoothly extended into the preset taking-out position. In the present embodiment, the housing 10 is a cylindrical housing, and the clearance between the outer diameter of the housing and the inner hole of the workpiece 11 is between 0.10mm and 0.20 mm. The cross-sectional dimension of the housing 10 is smaller than the aperture of the workpiece 11, and when the workpiece 11 needs to be taken out from the deep hole of the machine body, the taking and placing device can be extended into the deep hole. By setting the gap between the shell 10 and the inner hole of the workpiece 11 to be smaller, when the workpiece is picked and placed in the deep hole by using the picking and placing device, the workpiece 11 can be stably moved in the deep hole, and the workpiece 11 can be ensured not to be clamped with the inner wall of the deep hole.

By applying the taking and placing device provided by the embodiment, when the workpiece 11 needs to be taken out from the deep hole, firstly, the taking and placing assembly is in an avoiding state, the protruding part 21 is located at the inner side of the shell 10, the taking and placing device can extend into the hole of the workpiece 11, then, the taking and placing assembly is adjusted to be in a working state, so that the protruding part 21 protrudes to the periphery of the shell 10 and is abutted against the workpiece 11, the workpiece is limited by the protruding part 21, and the workpiece can be taken out from the deep hole by pulling the taking and placing device towards the outer side of the deep hole. By adopting the structure, the machine body does not need to be inverted, a large amount of manpower and material resources do not need to be consumed, and the overhauling efficiency can be improved.

When the pick-and-place assembly 20 is in an operating state, the protrusion 21 protrudes to the outer periphery of the housing 10 to abut against the workpiece 11, which includes the following two conditions:

first, the projecting portion 21 projects to the outer periphery of the housing 10 and abuts against the hole wall of the workpiece 11;

secondly, the projecting portion 21 projects to the outer periphery of the housing 10 and abuts against the lower surface of the workpiece 11.

By adopting the two schemes, when the taking and placing assembly 20 is in a working state, the workpiece can be limited by the convex part 21, so that the workpiece can be taken out from the deep hole by using the taking and placing device.

Specifically, the plurality of synchronizing gears 23 are engaged with each other, and the arrangement is such that when one of the synchronizing gears 23 rotates, the synchronizing gear 23 can drive the remaining synchronizing gears 23 to rotate simultaneously, and the rotation angle of each rotating shaft 22 is the same. In this embodiment, when the pick-and-place assembly 20 needs to be switched between the working state and the retracted state, one of the synchronizing gears 23 is shifted by a hand to simultaneously rotate the plurality of synchronizing gears 23, so that the protrusion 21 on each rotating shaft 22 can simultaneously abut against the workpiece 11 or be retracted into the housing 10. In other embodiments, the synchronizing gear 23 may be connected to a motor, and the motor may be used to rotate the synchronizing gear 23.

Specifically, the drive end of pivot 22 is provided with the screw thread section, gets and puts the device and still includes lock nut 30, lock nut 30 and screw thread section screw-thread fit, and one side and lock nut 30 butt of synchronizing gear 23, the opposite side and the step 221 butt on the drive end of synchronizing gear 23, lock nut 30 and step 221 cooperate in order to restrict the position of synchronizing gear 23 on pivot 22, avoid synchronizing gear 23 to break away from pivot 22.
