[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an automatic clamping device for a heart-shaped chuck, comprising a base 1, on which a rotating lever mechanism 2, a clamping mechanism 3, a heart-shaped chuck 4 for clamping the product and a pressing mechanism 5 are sequentially arranged. The rotating drive mechanism is connected to the base 1 through a fixed plate 11, the clamping mechanism 3 is connected to the base 1 through a connecting plate 12, and the pressing mechanism 5 is connected to the base 1 through a bottom plate 13. The clamping mechanism 3 is used to clamp the heart-shaped chuck 4, and the pressing mechanism 5 is used to press the heart-shaped chuck 4 onto the clamping mechanism 3.

[0026] The rotary lever mechanism 2 includes a rotary drive assembly 21, a rotating disk 22 and a lever 23 for moving the heart-shaped chuck 4. The driving end of the rotary drive assembly 21 is connected to the rotating disk 22, the lever 23 is fixedly connected to the rotating disk 22, and the lever 23 is located on one side of the heart-shaped chuck 4.

[0027] Specifically, the loading mechanism in the prior art first places the heart-shaped chuck 4 on the clamping mechanism 3, and the three-claw cylinder 31 of the clamping mechanism 3 drives the three clamping blocks 32 to clamp the heart-shaped chuck 4 at the same time, and then the heart-shaped chuck 4 is pressed onto the three clamping blocks 32 of the clamping mechanism 3 through the pressing mechanism 5, and then the rotating drive component 21 of the rotating lever mechanism 2 drives the rotating disk 22 to drive the lever 23 to move the clamping handle 43 of the heart-shaped chuck 4, and the heart-shaped chuck 4 opens. The loading mechanism in the prior art places the product into the heart-shaped chuck 4, and the rotating lever mechanism 2 drives the lever 23 to return to the initial position, so that the heart-shaped chuck 4 clamps the product, and then the three-claw cylinder 31 of the clamping mechanism 3 drives the three clamping blocks 32 to loosen the heart-shaped chuck 4, and the feeding mechanism in the prior art moves the heart-shaped chuck 4 and the product to the grinder, and the grinder processes the product. At the same time, the heart-shaped chuck 4 can make the product rotate during the grinding process. After the product processing is completed, the material removal mechanism transfers the heart-shaped chuck 4 and the product to the clamping mechanism 3. The clamping mechanism 3 clamps the heart-shaped chuck 4. The rotating lever mechanism 2 drives the lever 23 to open the heart-shaped chuck 4. The feeding mechanism removes the processed product. Finally, the pressing mechanism 5 presses and resets the heart-shaped chuck 4 to prevent it from deflecting.

[0028] In the above structure, by arranging the rotary lever mechanism 2, the clamping mechanism 3 and the pressing mechanism 5 to cooperate with each other, the automated clamping operation of the heart-shaped chuck 4 is realized, thereby improving the clamping efficiency and reducing the labor cost.

[0029] like Figure 2 As shown, in one embodiment, the clamping mechanism 3 of the automatic clamping device for the heart-shaped chuck includes a three-claw cylinder 31 and three clamping blocks 32. The driving ends of the three-claw cylinder 31 are respectively connected to the three clamping blocks 32. The three-claw cylinder 31 is used to drive the three clamping blocks 32 to clamp the heart-shaped chuck 4. When the heart-shaped chuck 4 is placed on the three clamping blocks 32, the three-claw cylinder 31 drives the three clamping blocks 32 to clamp the bottom end of the heart-shaped chuck 4 at the same time, thereby improving the fixation of the heart-shaped chuck 4.

[0030] like Figure 2 As shown, in one embodiment, each of the three clamping blocks 32 of the heart-shaped chuck automatic clamping device is provided with a positioning notch 321 for positioning the bottom of the heart-shaped chuck 4. The bottom end of the heart-shaped chuck 4 is placed on the positioning notches 321 of the three clamping blocks 32, respectively, and the positioning notches 321 are adapted to the bottom end of the heart-shaped chuck 4. The provision of the positioning notches 321 greatly improves the fixing effect between the clamping blocks 32 and the heart-shaped chuck 4.

[0031] like Figure 3As shown in one embodiment, the heart-shaped chuck 4 of the heart-shaped chuck automatic clamping device includes a chuck ring 41, a plurality of clamping bolts 42, a clamping handle 43, and a spring 44. The plurality of clamping bolts 42 are respectively threaded radially onto the chuck ring 41. The clamping handle 43 is eccentrically hinged to the chuck ring 41. One end of the spring 44 is connected to an end of the clamping handle 43 located outside the chuck ring 41. The other end of the spring 44 is connected to the outer wall of the chuck ring 41 via a connecting bolt 45. The shift rod 23 is located on one side of the clamping handle 43. Two clamping bolts 42 are provided on the chuck ring 41. The two clamping bolts 42 are respectively threaded onto the chuck ring 41. One end of the two clamping bolts 42 is respectively located within the chuck ring 41. The clamping handle 43 is eccentrically hinged to the chuck ring 41. The arcuate end 432 of the clamping handle 43 is located inside the chuck ring 41, and the handle end 431 of the clamping handle 43 is located outside the chuck ring 41. When placing a product, the rotary drive assembly 21 drives the lever 23 to move the handle end 431 of the clamping handle 43. The handle end 431 drives the arcuate end 432 to rotate outward, thereby increasing the space between the arcuate end 432 and the two clamping bolts 42. When the product is placed in place, the rotary drive assembly 21 drives the lever 23 to release the handle end 431 of the clamping handle 43. The handle end 431 returns to its original position under the force of the spring 44, and the arcuate end 432 returns to its original position. The arcuate end and the two clamping bolts 42 clamp the product. This arrangement facilitates the clamping of the product and improves the fixation of the product.

[0032] like Figure 3 As shown, in one embodiment, the thickness of the chuck ring 41 of the heart-shaped chuck automatic clamping device is 15 mm to 20 mm. The chuck ring 41 can be 15 mm, 17 mm, or 20 mm thick, with 17 mm being preferred. This thickness allows the chuck ring 41 to achieve good positioning and clamping effects with the positioning notch 321 of the clamping block 32.

[0033] like Figure 2 As shown, in one embodiment, the pressing mechanism 5 of the chicken heart chuck automatic clamping device includes a pressing cylinder 51 and a pressing plate 52. The driving end of the pressing cylinder 51 is connected to the pressing plate 52. The pressing cylinder 51 is used to drive the pressing plate 52 to press the chicken heart chuck 4 onto the clamping mechanism 3. When the chicken heart chuck 4 is clamped on the clamping mechanism 3, the pressing cylinder 51 drives the pressing plate 52 to press the two ends of the top of the chicken heart chuck 4, so that the chicken heart chuck 4 is pressed on the clamping mechanism 3, which can prevent the position of the chicken heart chuck 4 from being offset and ensure the accuracy of clamping during use.

[0034] like Figure 2 As shown, in one embodiment, the pressing plate 52 of the chicken heart chuck automatic clamping device is provided with a U-shaped groove 521 for the product to pass through. This arrangement facilitates the placement of the product into the chicken heart chuck 4 without affecting the pressing effect.

[0035] like Figure 2 As shown, in one embodiment, the rotary drive assembly 21 of the heart-shaped chuck automatic clamping device is a rotary cylinder.

[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
