[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figure 1 The present invention provides an adjustable gripper for a die casting extraction machine, including a gripper cylinder 1; each drive end of the gripper cylinder 1 is fixedly provided with a mounting base 2; and gripper assemblies 3 are separately provided on the top surface of each mounting base 2.

[0027] The gripper assembly 3 is fixedly connected to the mounting base 2 via an adjustable fixing assembly 4, which is used to adjust the fixed position of the gripper assembly 3 on the mounting base 2 along the radial direction of the gripper cylinder 1.

[0028] A positioning structure 5 is provided between the gripper assembly 3 and the mounting base 2 to position the gripper assembly 3 and improve the stability of the gripper assembly 3.

[0029] In this embodiment, when gripping the formed die-cast part, the adjustable fixing component 4 fixes the gripper component 3 to the corresponding position according to the size of the die-cast part. The positioning structure 5 positions each fixing component 4 to ensure that they are all placed in the same preset position, thus ensuring the gripping effect of the gripper and effectively improving the applicability of the gripper. For die-cast parts with varying die-cast part sizes, the position of the gripper component 3 can be adjusted to grip them without replacing the gripper, improving the convenience of using the gripper.

[0030] In a preferred embodiment, such as Figure 1 As shown, the gripper cylinder 1 is a three-jaw cylinder or a four-jaw cylinder, which firmly grips the material cake.

[0031] In a preferred embodiment, such as Figure 1 As shown, the mounting base 2 is fixedly installed on the drive end of the gripper cylinder 1 by the first screw 21, which is convenient to install and secure. The mounting base 2 is long and strip-shaped and arranged radially along the gripper cylinder 2, which is suitable for adjusting the fixed position of the gripper assembly 3.

[0032] In a preferred embodiment, such as Figure 1As shown, the gripper assembly 3 includes a gripper seat 31 and a gripper head 32. The gripper seat 31 is separately disposed on the top surface of the mounting base 2. The top of the gripper seat 31 has a through hole 33 along the radial direction of the gripper cylinder 1. The gripper head 32 is disposed on the inner side of the gripper seat 31 and is fixedly connected to a screw 34 that passes through the through hole 33. A nut 35 is threadedly connected to one end of the screw 34 that passes through the through hole 33.

[0033] In this embodiment, the gripper head 32 is mounted onto the mounting base 2 via the gripper seat 31, which is convenient and secure. The gripper head 32 adopts a replaceable mounting structure, which allows for the replacement of gripper heads 32 of different shapes according to different gripping needs, and also facilitates the replacement of gripper heads 32 after wear.

[0034] In a preferred embodiment, such as Figure 1 As shown, the adjustable fixing component 4 includes a second screw 41. The top surface of the mounting base 2 is provided with a plurality of screw holes 42 symmetrically and equally spaced on both sides of the radial direction of the gripper cylinder 1. The gripper assembly 3 is connected to the screw holes 42 by at least two second screws 41.

[0035] In this embodiment, the gripper seat 31 is moved radially along the gripper cylinder 1 on the mounting base 2. After moving to the target position, the gripper seat 31 is fixed by connecting the corresponding screw hole 42 through the second screw 41. The adjustment is convenient and the fixation is stable, which improves the applicability of the gripper.

[0036] In a preferred embodiment, such as Figure 1 As shown, the positioning structure 5 includes slots 51 and blocks 52. Several slots 51 are symmetrically arranged at equal intervals on both sides of the mounting base 2. The spacing between adjacent slots 51 on the same side is the same as the spacing between screw holes 42. Blocks 52 are symmetrically arranged on both sides of the bottom of the gripper assembly 3. The blocks 52 on both sides of the bottom of the gripper assembly 3 are adapted to be embedded in the slots 51 on both sides of the mounting base 2.

[0037] In this embodiment, when adjusting the position of the gripper assembly 3, the locking blocks 52 on each set of gripper assemblies 3 are all locked into the corresponding slots 51 on the mounting base 2 at the same position, so that the distance from each set of gripper assemblies 3 to the axis of the gripper cylinder 1 is consistent, which ensures the gripping effect of the gripper and improves the stability of the gripper assembly 3.

[0038] In a preferred embodiment, such as Figure 1 As shown, the spacing between adjacent slots 51 on the same side is 10mm. Each time the locking block 52 moves the locking position of a slot 51, the clamping size of the jaws is adjusted by 10mm, which meets the clamping requirements of most die-cast parts.

[0039] In a preferred embodiment, such as Figure 1As shown, a positioning distance mark 53 is provided on either side of the mounting base 2 below the slot 51, which makes it easy for the user to move each set of gripper assemblies 3 to the same fixed position that meets the requirements, thus improving the convenience of gripper adjustment.
