Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 , an automatic insert placement device, including: an automatic gripper 1 and a positioning base 2 for placing an insert mounting plate, and a clamping assembly 3 and an auxiliary assembly 4 are arranged on the positioning base 2.

[0025] The clamping assembly 3 includes a movable clamping plate 31 slidably arranged on the positioning base 2, a fixed clamping plate 32 fixedly installed on the positioning base 2, a threaded rod 33 rotatably arranged on the positioning base 2 and threadedly connected to the movable clamping plate 31, a connecting shaft 36 rotatably arranged inside the positioning base 2 and fixedly connected to the threaded rod 33, a turntable 34 fixedly installed on the end face of the connecting shaft 36, a fixed seat 311 fixedly installed on the turntable 34, a connecting circular shaft 313 rotatably connected to the fixed seat 311, an extension rod 35 fixedly connected to the connecting circular shaft 313, a return torsion spring 312 fixedly connected to the connecting circular shaft 313 and the fixed seat 311 at both ends, a ball head rod 38 slidably arranged inside the connecting shaft 36, a connecting rod 39 fixedly connected to the ball head rod 38, a friction ring 37 fixedly connected to the connecting rod 39, and a first spring 310 fixedly connected to the ball head rod 38 and the connecting shaft 36 at both ends; the ball head end of the ball head rod 38 can pass through the turntable 34 to contact the extension rod 35, the friction ring 37 can contact the positioning base 2 to form a contact surface, and friction lines for enhancing the friction between the friction ring 37 and the positioning base 2 are arranged on the contact surface. The friction force formed by the friction lines can be used to lock the state of the overall structure, thereby improving the stability of the overall device. A chute for passing through the connecting rod 39 is opened on the connecting shaft 36, and both ends of the chute are designed to be sealed.

[0026] The auxiliary assembly 4 includes a rotating rod 41 rotatably connected to the positioning base 2, a first pressing plate 42 slidably arranged inside the movable clamping plate 31, a second spring 43, a connecting rod 44 fixedly connected to the first pressing plate 42, a guide rail 45 slidably arranged inside the positioning base 2, an elliptical block 46 fixedly connected to the rotating rod 41, a second pressing plate 47 slidably arranged inside the fixed clamping plate 32, and a fixed rod 48 fixedly connected to the second pressing plate 47 and the guide rail 45 at both ends. The connecting rod 44 is designed in a T shape and is slidably connected to the guide rail 45. The elliptical block 46 is located below the guide rail 45, and the arc surface of the elliptical block 46 is tangent to the bottom surface of the guide rail 45. There are two second springs 43 in total. One end of one second spring 43 is fixedly connected to the first pressing plate 42 and the movable clamping plate 31 respectively, and the other end of the other second spring 43 is fixedly connected to the second pressing plate 47 and the fixed clamping plate 32 respectively. The elastic force of the second spring 43 can be effectively utilized to make the insert mounting plate closely contact the positioning base 2, thereby ensuring the positioning effect of the positioning base 2. A knob is arranged on the end of the rotating rod 41 passing through the positioning base 2, and anti-slip lines are arranged on the knob to avoid the phenomenon of the user's hand slipping, thereby ensuring the practicality of these structures.

[0027] Working principle: First, rotate the extension rod 35 through the finger ring on the extension rod 35 so that the extension rod 35 does not contact the ball head end of the ball head rod 38. Since the first spring 310 is used to further connect the connecting shaft 36 on the end face of the ball head rod 38, and the connecting rod 39 fixed on the ball head rod 38 is slidably connected to the connecting shaft 36, and the friction ring 37 is also fixed on the connecting rod 39. Therefore, under the elastic force of the first spring 310, the ball head rod 38, the friction ring 37 and the connecting rod 39 slide. At this time, a gap will be generated between the friction ring 37 and the positioning base 2. After the extension rod 35 drives the turntable 34 to rotate, the connecting shaft 36 fixedly connected to the turntable 34 rotates synchronously inside the positioning base 2. And the connecting shaft 36 is fixedly connected to the threaded rod 33, and the threaded rod 33 rotates synchronously. And the movable clamping plate 31 slidably arranged on the positioning base 2 is also threadedly connected to the threaded rod 33. Then, after the threaded rod 33 rotates, the movable clamping plate 31 will rotate on the positioning base 2 and reduce the gap with the fixed clamping plate 32, thereby clamping and restricting the position of the insert mounting plate on the positioning base 2. Subsequently, release the extension rod 35. Since the extension rod 35 is movably connected to the fixed seat 311 fixed on the turntable 34 through the connecting round shaft 313, and the connecting round shaft 313 is further connected to the fixed seat 311 by using a return torsion spring 312. Therefore, under the action of the return torsion spring 312, the extension rod 35 is driven to rotate and contact the ball head rod 38, thereby squeezing the ball head rod 38, the connecting rod 39 and the friction ring 37 to slide, eliminating the gap between the friction ring 37 and the positioning base 2. At this time, a certain frictional force can be generated between the friction lines on the friction ring 37 and the positioning base 2 to restrict the rotation of the friction ring 37, thereby locking the rotation of the connecting shaft 36 and the threaded rod 33, and further locking the position of the movable clamping plate 31.

[0028] Before the movable clamping plate 31 and the fixed clamping plate 32 clamp the insert mounting plate, the rotating rod 41 can be rotated. The elliptical block 46 arranged inside the positioning base 2 rotates with the rotation of the rotating rod 41. After the elliptical block 46 rotates, it can push the guide rail 45 to slide upward. Among them, the connecting rod 44 slidably connected to the guide rail 45 is fixed on the first pressing plate 42, and the fixed rod 48 fixedly connected to the guide rail 45 is fixed on the second pressing plate 47. Therefore, the first pressing plate 42 and the second pressing plate 47 slide upward together with the guide rail 45, increasing the gap between them and the positioning base 2. At this time, the insert mounting plate is placed inside this gap. Subsequently, release the rotating rod 41, and under the action of the second spring 43, the first pressing plate 42 and the second pressing plate 47 will be pushed to slide downward, squeezing the insert mounting plate to ensure that the insert mounting plate and the positioning base 2 can be in close contact to ensure the positioning effect of the positioning base 2.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
