[0024] For the convenience of understanding the present utility model, the following will describe the present utility model more comprehensively and meticulously in combination with the accompanying drawings of the specification and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.

[0025] Unless otherwise defined, all professional terms used hereinafter have the same meaning as commonly understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the protection scope of the present utility model.

[0026] Unless otherwise specifically stated, various raw materials, reagents, instruments, equipment, etc. used in the present utility model can be obtained through the market or can be prepared by existing methods.

[0027] Please refer toFigure 1 and 2 , a fixture 100 for an isostatic graphite product gripping robot according to an embodiment is installed on the robotic arm of the isostatic graphite product gripping robot. The fixture 100 for the isostatic graphite product gripping robot specifically includes: a mounting plate 10, a connecting flange 20, a clamping portion 30, a driving member 40, and a guide rail translation member 50. One end of the connecting flange 20 is connected to the robotic arm of the isostatic graphite product gripping robot in a multi-angle movable manner, and the other end is fixed to the mounting plate 10. The clamping portion 30 includes a pair of chucks 32 arranged oppositely. The driving member 40 includes a pair of cylinders 42, and the cylinders 42 are fixed to the mounting plate 10. Among the pair of guide rail translation members 50, each guide rail translation member 50 is correspondingly connected to a cylinder 42 and a chuck 32; the cylinders 42 move in a telescopic manner to drive the guide rail translation members 50 to move, thereby driving the pair of chucks 32 to approach each other to grip the graphite product or move away from each other for unloading.

[0028] In the fixture 100 for the isostatic graphite product gripping robot of the present application, the connecting flange 20 is connected to the robotic arm of the isostatic graphite product gripping robot in a multi-angle movable manner, so that it can rotate and move flexibly, facilitating free gripping at multiple angles. The cylinders 42 move in a telescopic manner to drive the guide rail translation members 50 to move, thereby driving the pair of chucks 32 to approach each other to grip the graphite product or move away from each other for unloading. The structure is simple, and since the guide rail translation members 50 limit the translation path, the chucks 32 are not prone to angular deviation during the process of gripping the isostatic graphite product and unloading, and the gripping accuracy is improved.

[0029] Specifically, in one embodiment, the mounting plate 10 is generally rectangular and is mainly used to fix various components. The mounting plate 10 has a hollow structure 12 at the place where components are not connected or fixed, so as to reduce the mass of the whole machine.

[0030] Both ends of the connecting flange 20 are provided with flange structures, and the middle is a hollow tube structure. One end is fixed to the mounting plate 10 through an end flange, and the other end is connected to the robotic arm of the isostatic graphite product gripping robot in a multi-angle movable manner through an end flange.

[0031] The clamping portion 30 includes a pair of chucks 32 arranged oppositely. The chuck 32 includes a clamping plate 320 and a clamping portion 322 fixed to the clamping plate 320. The opposite sides of the clamping portion 322 are formed to match the shape of the product to be gripped. For example, when used for gripping carbon rods, the opposite sides are arc-shaped sides. Preferably, there are multiple arc-shaped sides, such as 2, fixed to the clamping plate 320. The clamping plate 320 between adjacent arc-shaped sides is hollowed out. The multiple arc-shaped sides can increase the contact area between the clamping portion 322 and the carbon rod, provide a greater acting force, and at the same time reduce the weight of the clamping plate 320 itself, so as to achieve the gripping of large-mass carbon rods.

[0032] The driving member 40 includes a pair of cylinders 42, and the cylinders 42 are fixed on the mounting plate 10. Preferably, in one embodiment, a floating joint 420 is provided at each end of the cylinder. The floating joint 420 can eliminate the errors caused by insufficient parallelism or non - concentricity between the cylinder 42 and the driven member.

[0033] Preferably, the guide rail translation member 50 is a guide rail slider assembly, including a first guide rail 520 fixed on the mounting plate 10 and a first slider 522 translating along the first guide rail 520, and a second guide rail 524 fixed on the mounting plate 10 and a second slider 526 translating along the second guide rail 524. One of the chucks 32 is connected to the first slider 522, and the other chuck 32 is connected to the second slider 526. When the chuck 32 is working under long - term load, problems such as reduced smoothness of movement and poor gripping accuracy may occur. By the guide rail slider assembly, the movement path is restricted, the movement deviation is reduced, and the smoothness is provided. In other embodiments, the guide rail translation member 50 can also be a linear bearing, etc. Preferably, one of the cylinders 42 is connected to the first slider 522 through a first conduction plate 44, and the other cylinder 42 is connected to the second slider 522 through a second conduction plate 46.

[0034] In one embodiment, a synchronization component 60 is further included. The synchronization component 60 includes a synchronization gear 62 fixed on the mounting plate 10, a first rack 64 and a second rack 66 meshing with the synchronization gear 62. The first slider 522 is connected to the first rack 64, and the second slider 526 is connected to the second rack 66. During gripping, the mutual cooperation of the chucks 32 requires high precision. Especially for gripping large - mass products, such as large - mass carbon rods, if the alignment accuracy decreases, problems such as unsuccessful gripping or dropping of the product during gripping may occur. Through the meshing of the synchronization gear 62 with the first rack 64 and the second rack 66, the two chucks 32 move precisely synchronously, improving the gripping accuracy. In one embodiment, the first slider 522 and the second slider 526 are respectively inlaid and connected with the corresponding first guide rail 520 and the second guide rail 524, and the first slider 522 and the second slider 526 are respectively fastened to the corresponding chucks 32 with screws. The above structure enhances the stability and smoothness of the chucks 32 during movement.

[0035] Preferably, there are two first sliders 522, both connected to the first rack 64, and there are two second sliders 526, both connected to the second rack 66. By setting the first sliders 522 and the second sliders 526 to be two, the stability and balance are better.

[0036] In the fixture 100 for the isostatic graphite product grabbing robot of the present application, it can be movably connected to the robotic arm of the isostatic graphite product grabbing robot at multiple angles through the connecting flange 20, so that it can rotate and move flexibly, facilitating free grabbing at multiple angles. The telescopic movement of the cylinder 42 drives the movement of the guide rail translation member 50 to drive a pair of chucks 32 to approach each other to grab the graphite product or move away from each other for discharging. The structure is simple, and since the guide rail translation member 50 restricts the translation path, the chucks 32 will not deviate in angle during the process of clamping the isostatic graphite product and discharging. Further, through the cooperation of the guide rail translation member 50 and the synchronous component 60 on the chuck 32, the fixture 100 for the isostatic graphite product grabbing robot of the present application can be used for grabbing products with relatively large mass, and can be used for grabbing cylindrical isostatic graphite products, such as carbon rods. When the device is working, the chucks are in the normally open state. The robotic arm drives the entire device to the carbon rod discharging port of the die casting machine. The robotic arm rotates the angle so that the carbon rod to be discharged is located between the two chucks 32. The two chucks 32 start to close, causing the carbon rod to be clamped. The robotic arm drives the entire device to the material box position, and the chucks 32 are loosened to complete the entire discharging action.
