[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0040] like Figure 1-Figure 7 As shown, a nut picking fixture suitable for an injection molding machine includes: a lower plate body 100, an upper plate body 200 and a clamping assembly.

[0041] The lower plate body 100 is provided with a positioning column 110, and the positioning column 110 is used to fix the nut.

[0042] Among them, the upper plate body 200 can be raised and lowered and can be close to or away from the lower plate body 100. The upper plate body 200 is provided with a clamping tube 210, and the clamping tube 210 is provided with a clamping hole. When the upper plate body 200 approaches the lower plate body 100, it drives the positioning column 110 to be inserted into the clamping tube 210.

[0043] Among them, the clamping assembly includes a clamping seat 310, a clamping piece and a reset piece. The clamping seat 310 is connected to the clamping tube 210 and is located in the clamping hole. The clamping piece is movably connected to the clamping seat 310. The reset piece is used to drive the clamping piece away from the clamping seat 310 and protrude from the clamping hole.

[0044] Specifically, when the upper plate body 200 is close to the lower plate body 100, the positioning column 110 is continuously inserted into the clamping tube 210 and is used to drive the nut to slide along the clamping tube 210 until it contacts the clamping piece and pushes the clamping piece into the clamping hole until the clamping piece is aligned with the groove of the nut, and the reset piece pushes the clamping piece to protrude out of the clamping hole and is used to embed into the groove of the nut.

[0045] Specifically, when the upper plate body 200 is away from the lower plate body 100, the clamping member remains protruding from the clamping hole and embedded in the nut groove, thereby driving the nut to be lifted.

[0046] In this embodiment, the upper plate body 200 is moved closer to or away from the lower plate body 100 to drive the clamping assembly closer to or away from the positioning column 110, and the reset member is used to drive the clamping member away from the clamping seat 310 and protrude from the clamping hole and embed into the groove of the nut to clamp the nut. In the case of mass production, multiple positioning columns 110 are set on the lower plate body 100, and corresponding clamping assemblies are set on the upper plate body 200 to achieve simultaneous clamping of multiple groups of nuts.

[0047] like Figure 1-Figure 7As shown, on the basis of the above embodiment, the clamping seat 310 is provided with a movable hole 312 , and the clamping member is provided in the movable hole 312 and can move along the length direction of the movable hole 312 .

[0048] In this embodiment, the clamping member is disposed in the movable hole 312 disposed in the clamping seat 310 and can move along the length direction of the movable hole 312, thereby effectively preventing the clamping member from falling off the clamping seat 310 during the movement.

[0049] like Figure 1-Figure 7 As shown, based on the above embodiment, the reset member is a spring 330, and the spring 330 is located between the clamping seat 310 and the clamping member, one end of the spring 330 contacts the clamping seat 310, and the other end of the spring 330 contacts the clamping member, and the spring 330 pushes the clamping member away from the clamping seat 310 and protrudes out of the clamping hole.

[0050] In this embodiment, the spring 330 pushes the clamping piece away from the clamping seat 310 and protrudes out of the clamping hole, so when the clamping piece is aligned with the nut, it is pushed back to the clamping hole by the nut. When the clamping piece is aligned with the groove of the nut, the spring 330 pushes the clamping piece to protrude out of the clamping hole and embed into the groove of the nut.

[0051] like Figure 1-Figure 7 As shown, on the basis of the above embodiment, the clamping member is configured as a clamping ball 320 , and the clamping ball 320 is disposed in the movable hole 312 and can roll along the length direction of the movable hole 312 .

[0052] In this embodiment, the clamping member is set as a clamping ball 320, so that the clamping ball 320 is set in the movable hole 312 and can roll along the length direction of the movable hole 312, making the movement more flexible. At the same time, the sliding friction is converted into rolling friction, reducing the wear caused by the friction between the clamping ball 320 and the movable hole 312.

[0053] like Figure 1-Figure 7 As shown, based on the above embodiment, the clamping seat 310 is detachably connected to the clamping tube 210 .

[0054] In this embodiment, the manner in which the clamping seat 310 is detachably connected to the clamping tube 210 is not specifically limited, and may be a snap connection, a plug connection, or a fastener connection, etc.

[0055] like Figure 1-Figure 7 As shown, based on the above embodiment, the clamping hole is set as a threaded hole 211, and the clamping seat 310 is provided with a threaded portion 311, and the clamping seat 310 can be threadedly connected with the threaded hole 211 of the upper plate body 200 through the threaded portion 311.

[0056] In this embodiment, the clamping seat 310 can be threadedly connected to the threaded hole 211 of the upper plate body 200 through the threaded portion 311. The clamping seat 310 is also provided with a special-shaped hole, so that the user can use the corresponding tool to align the special-shaped hole and screw it to drive the clamping seat 310 and the clamping tube 210 to tighten.

[0057] like Figure 1-Figure 7 As shown, on the basis of the above embodiment, it also includes a material unloading component, which includes a material unloading block 410 and a material unloading driving element 420. The material unloading block 410 is located in the clamping tube 210, and the material unloading driving element 420 is connected to the upper plate body 200. The material unloading block 410 is connected to the material unloading driving element 420, and the material unloading driving element 420 can drive the material unloading block 410 to move along the length direction of the clamping tube 210.

[0058] In this embodiment, the material removal driving element 420 can drive the material removal block 410 to move along the length direction of the clamping tube 210 , thereby pushing the nut of the clamped part embedded in the groove to move, thereby making it withdraw from the clamping tube 210 .

[0059] like Figure 1-Figure 7 As shown, on the basis of the above embodiment, it also includes a finger cylinder 500 and a flip driving element 600, the finger cylinder 500 is connected to the upper plate body 200 and is located on the side opposite to the clamping assembly, the upper plate body 200 is connected to the flip driving element 600, and the flip driving element 600 can drive the upper plate body 200 to rotate so that the clamping assembly or the finger cylinder 500 is aligned with the positioning column 110.

[0060] Specifically, the flip driving element 600 may be a motor.

[0061] It is worth mentioning here that the finger cylinder 500 can play the same role as the clamping component, but the pipeline routing of the cylinder continues, and because the nut is exposed to the outside world, it is easy to fall off due to external forces.

[0062] In this embodiment, the upper plate 200 is driven to rotate by the flipping drive element 600 so that the clamping assembly or the finger cylinder 500 is aligned with the positioning column 110, thereby providing two different clamping methods. At the same time, through the cooperation of the clamping assembly, the finger cylinder 500 and the flipping drive element 600, it is possible to clamp twice the number of nuts as the positioning column 110.

[0063] like Figure 1-Figure 7As shown, based on the above embodiment, the lower plate body 100 is further provided with a guide column 120, and the upper plate body 200 is further provided with a guide hole. When the upper plate body 200 approaches or moves away from the lower plate body 100, the guide column 120 can slide along the guide hole.

[0064] In this embodiment, the guide post 120 can slide along the guide hole to guide the upper plate 200 to rise and fall relative to the lower plate 100 , so that the gripping assembly or the finger cylinder 500 is aligned with the positioning post 110 .

[0065] An injection molding machine is also provided, comprising the above-mentioned nut taking fixture suitable for the injection molding machine.
