[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0026] Embodiment

[0027] As shown in Figure 1 , 2 , 5, and 6, it includes a frame body 1. An adjustment mechanism 2 is provided at the top of the frame body 1. A grasping mechanism 3 is provided on one side of the adjustment mechanism 2. The grasping mechanism 3 includes a third driving motor 302 installed at the bottom of the second sliding plate 207. A connecting column 304 is axially connected to the bottom of the third driving motor 302. A connecting plate 305 is provided at the bottom of the third driving motor 302. A threaded column 306 is threadedly connected to the inner wall of the connecting column 304. A clamping arm 307 is provided at the bottom of the connecting plate 305. A movable block 309 is provided at the bottom of the threaded column 306.

[0028] It should be noted that in this embodiment, when clamping the plastic part, the third driving motor 302 drives the connecting column 304 to rotate. The threaded column 306 threadedly connected to the inner wall of the connecting column 304 moves in the vertical direction under the rotation of the connecting column 304. The movable block 309 at the bottom of the threaded column 306 moves together with the threaded column 306. When the movable block 309 moves, the inner wall of the second connecting disk 308 can play a certain guiding role. The mounting member 311 at the bottom of the movable block 309 is rotatably connected to the clamping arm 307 through the connecting block 310. When the movable block 309 moves, force is transmitted through the mounting member 311 and the connecting block 310, causing the clamping arm 307 to rotate around the connection point with the connecting plate 305. When the movable block 309 moves upward, the clamping arm 307 gradually opens; when the movable block 309 moves downward, the clamping arm 307 gradually closes, realizing the grasping and releasing of the plastic part. The first connecting disk 303 is used to connect the third driving motor 302 and the connecting plate 305;

[0029] Among them, the driving cylinder 301 generates thrust or pulling force. Under the push of the driving cylinder 301, it is convenient for the grasping mechanism 3 to adjust the grasping position so as to grasp the plastic part more accurately.

[0030] As Figure 1-4 shown, the adjusting mechanism 2 includes a first driving motor 201 installed on one side of the frame body 1. A first sliding plate 202 is provided on the inner wall of the frame body 1, and the first sliding plate 202 is slidably connected to the frame body 1. Two groups of fixing plates 203 are provided at the bottom of the frame body 1. A first sliding groove 204 is provided at one end of the frame body 1. One side of the first driving motor 201 is axially connected to a first threaded rod 205. One end of the first sliding plate 202 is provided with a second driving motor 206. A second sliding plate 207 is provided on the inner wall of the first sliding plate 202, and the second sliding plate 207 is slidably connected to the first sliding plate 202. A second sliding groove 208 is provided on one side of the first sliding plate 202. One end of the second driving motor 206 is axially connected to a second threaded rod 209.

[0031] It should be noted that in this embodiment, first, the first driving motor 201 and the second driving motor 206 are started. The first driving motor 201 drives the first threaded rod 205 to rotate. The rotation of the first threaded rod 205 will generate an axial driving force. Under the drive of the first threaded rod 205, the first sliding plate 202 moves horizontally along the frame body 1. The second driving motor 206 drives the second threaded rod 209 to rotate. The rotating second threaded rod 209 generates an axial force acting on the second sliding plate 207. Under the drive of the second threaded rod 209, the second sliding plate 207 moves vertically along the first sliding plate 202, thereby driving the grasping mechanism 3 to adjust its position in the vertical direction;

[0032] One end of the first slide plate 202 is embedded in the inner wall of the first chute 204, so that the first slide plate 202 slides more smoothly when a certain pressure is applied to one end thereof. One side of the second slide plate 207 is embedded in the inner wall of the second chute 208, so that the second slide plate 207 slides more smoothly when a certain pressure is applied to one side thereof. The fixing plate 203 installed at the bottom of the frame body 1 increases the stability of the frame body 1.

[0033] The working principle of the present utility model:

[0034] Refer to the attached drawings of the specification Figure 1-6 , first start the first driving motor 201 and the second driving motor 206. The first driving motor 201 drives the first threaded rod 205 to rotate. The rotation of the first threaded rod 205 generates an axial driving force. Under the drive of the first threaded rod 205, the first slide plate 202 moves horizontally along the frame body 1. The second driving motor 206 drives the second threaded rod 209 to rotate. The rotating second threaded rod 209 generates an axial force acting on the second slide plate 207. Under the drive of the second threaded rod 209, the second slide plate 207 moves vertically along the first slide plate 202, thereby driving the grasping mechanism 3 to adjust its position vertically;

[0035] When clamping a plastic part, the third driving motor 302 drives the connecting column 304 to rotate. The threaded column 306 threadedly connected to the inner wall of the connecting column 304 moves vertically under the rotation of the connecting column 304. The movable block 309 at the bottom of the threaded column 306 moves together with the threaded column 306. When the movable block 309 moves, the inner wall of the second connecting disk 308 can play a certain guiding role. The mounting member 311 at the bottom of the movable block 309 is rotatably connected to the clamping arm 307 through the connecting block 310. When the movable block 309 moves, force is transmitted through the mounting member 311 and the connecting block 310, causing the clamping arm 307 to rotate around the connection point with the connecting plate 305. When the movable block 309 moves upward, the clamping arm 307 gradually opens; when the movable block 309 moves downward, the clamping arm 307 gradually closes, realizing the grasping and releasing of the plastic part. The first connecting disk 303 is used to connect the third driving motor 302 and the connecting plate 305;

[0036] Finally, under the push of the driving cylinder 301, it is convenient for the grasping mechanism 3 to adjust the grasping position so as to grasp the plastic part more accurately.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
