[0024] As Figures 1 to 4 shown, a mechanical fixture protection component includes a driving arm 101, two groups of chucks 102 are arranged at the front end of the driving arm 101, and a driving component for driving the two groups of chucks 102 is arranged on the driving arm 101;

[0025] It should be noted here that: the driving component is a conventional technical means for driving the chuck 102 on the mechanical fixture, and its working principle is relatively mature, so it will not be further described in this application;

[0026] It further includes a rubber pad 2 fixed on the opposite side of the two groups of chucks 102 for clamping protection, and a blanking component for quickly blanking after clamping is arranged on the chuck 102;

[0027] The blanking component includes an installation cavity 301 opened inside the chuck 102, a plurality of sliding holes 302 are opened on the opposite side of the two groups of chucks 102, each sliding hole 302 communicates with the inside of the installation cavity 301, a push rod 303 is slidably connected to each sliding hole 302, an installation plate 304 is arranged inside the installation cavity 301, one end of each push rod 303 is fixed to the installation plate 304, a transmission plate 4 is arranged inside the installation cavity 301, an elastic component for elastically connecting the installation plate 304 is arranged between the transmission plate 4 and the installation plate 304, and an adjustment component for adjusting the elasticity of the elastic component is arranged on the chuck 102;

[0028] During the process of the mechanical fixture clamping the workpiece, through the mutual cooperation of the rubber pad 2 and the blanking component, it can not only effectively protect the workpiece during the clamping process and avoid damage to the workpiece caused by clamping, but also push the workpiece to separate from the chuck 102 and the rubber pad 2 after clamping, so as to avoid adhesion between the workpiece and the rubber pad 2 after clamping and affect the normal unloading operation.

[0029] A plurality of rubber pads 2 are arranged on one side of the chuck 102, and the plurality of rubber pads 2 are arranged in a uniformly distributed state; through the plurality of uniformly arranged rubber pads 2, the protection effect is improved.

[0030] A plurality of elastic components are arranged between the transmission plate 4 and the installation plate 304, and the plurality of elastic components are arranged in a uniformly distributed state between the transmission plate 4 and the installation plate 304; through the plurality of uniformly arranged elastic components, the effect of elastic pushing is ensured.

[0031] The elastic component includes a sleeve 501 fixed on the mounting plate 304. A sliding rod 502 is slidably connected to the sleeve 501. One end of the sliding rod 502 is fixed to the transmission plate 4. A spring 503 is sleeved outside the sleeve 501. Through the sleeve 501 and the sliding rod 502, the telescopic movement of the mounting plate 304 is facilitated. Through the spring 503, it is convenient to reset the mounting plate 304 after the contraction movement.

[0032] The adjusting component includes a threaded sleeve 601 fixed on the chuck 102. A threaded rod 602 is threadedly engaged with the threaded sleeve 601. One end of the threaded rod 602 is rotatably connected to one side of the transmission plate 4. When the threaded rod 602 is rotated, during the rotation of the threaded rod 602, through the meshing transmission between the threaded rod 602 and the threaded sleeve 601, the transmission plate 4 moves inside the installation cavity 301. Through the movement of the transmission plate 4, the distance between the transmission plate 4 and the mounting plate 304 after being squeezed and contracted is adjusted. Through the adjustment of the distance, it is convenient for the spring 503 between the transmission plate 4 and the mounting plate 304 to generate different elastic forces, and further it is convenient to push and separate the workpiece more flexibly.

[0033] The other end of the threaded rod 602 is fixed with a driving pin 603 for driving the rotation of the threaded rod 602. Through the driving pin 603, it is convenient to rotate the threaded rod 602.

[0034] During the process of the mechanical fixture clamping the workpiece, through the movement of the driving arm 101, the workpiece to be clamped is placed between the two chucks 102. Then, through the driving component, the two chucks 102 are driven to move closer to each other to clamp the workpiece. During the clamping process, multiple rubber pads 2 on one side of the two chucks 102 are in contact with the outer side of the workpiece, playing a role in protecting the workpiece during the clamping process;

[0035] During the process of driving the two chucks 102 to move closer to each other to clamp and protect the workpiece, as the chucks 102 move, each push rod 303 is in contact with the outer side of the workpiece. During the contact process, each push rod 303 is pushed to contract towards the inside of the installation cavity 301 on each slide hole 302. During the contraction movement of the push rod 303, the mounting plate 304 is pushed to move towards the transmission plate 4 under force. During the movement of the mounting plate 304, each sliding rod 502 is pushed to slide on each sleeve 501 and the spring 503 is deformed under force to generate elastic force;

[0036] After the workpiece is clamped and moved, the two sets of chucks 102 are driven to move away from each other to release the clamping operation on the workpiece. During the process of the two sets of chucks 102 moving away from each other, through the elastic force of the spring 503 on the elastic component acting on the mounting plate 304, each set of push rods 303 is pushed outwards from the sliding holes 302. During the process of extension, each set of push rods 303 abuts against the clamped workpiece, pushing the workpiece to separate from the chuck 102 and the rubber pad 2, avoiding the adhesion between the clamped workpiece and the rubber pad 2 and affecting the normal unloading operation.

[0037] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
