[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figure 1-3 The connecting rod horizontal hydraulic tooling of the present invention comprises a base 1, on which a clamping mechanism 2 and a centering mechanism 3 are provided. The centering mechanism 3 comprises a left-right centering mechanism 31 and a front-back centering mechanism 32.

[0026] The front-to-back centering mechanism 32 includes four first positioning heads 321 symmetrically arranged in pairs. The first positioning heads 321 symmetrically arranged in pairs complete the front-to-back centering by clamping symmetrically and equidistantly toward the middle.

[0027] The left-right centering mechanism 31 includes a support portion 311 provided at one end of the workpiece A to be processed and a second positioning head 312 provided in the middle of the workpiece to be processed. The support portion 311 supports the lower part and the top part of one end of the workpiece A to be processed.

[0028] The first positioning head 321 adopts a clamping cylinder;

[0029] The second positioning head 312 adopts a connecting rod clamping structure driven by an oil cylinder.

[0030] The clamping mechanism 2 includes a first clamping mechanism 21, a second clamping mechanism 22, and a third clamping mechanism 23 disposed at both ends of the workpiece A to be processed. The first clamping mechanism 21 includes a floating clamping head 211 and an auxiliary support head 212 located below the floating clamping head 211. The second clamping mechanism 22 includes a Y-shaped connecting rod clamping head 221 and a second support portion 222 located below the Y-shaped connecting rod clamping head 221. The third clamping mechanism 23 includes an intermediate connecting rod clamping head 231 and a support head located below the intermediate connecting rod clamping head 231. The floating clamping head 211 allows the clamping force to be more evenly applied to one end of the workpiece A to be processed, ensuring a firm clamping. The Y-shaped connecting rod clamping head 221, the second support portion 222, and the intermediate connecting rod clamping head 231 at the other end prevent the workpiece A from rocking back and forth. After processing, the auxiliary support head 212 lifts one side of the workpiece for easy removal.

[0031] Auxiliary assembly clamps 4 are also provided at both ends of the workpiece A to be processed. Wear-resistant blocks are provided on the end points of the auxiliary assembly clamps 4 to make them more wear-resistant and increase the service life of the auxiliary assembly clamps 4.

[0032] The opening of the auxiliary assembly clamp 4 is adjustable, and workpieces of different widths can be processed.

[0033] A slide rail 41 is provided between the auxiliary assembly clamp 4 and the base 1 , so that workpieces of different lengths can be processed.

[0034] Working principle:

[0035] Place the workpiece A to be processed into the connecting rod horizontal hydraulic tooling described in the utility model. Under the preliminary positioning of the auxiliary assembly clamp 4, the workpiece A to be processed initially reaches the assembly position on the tooling. At this time, the first positioning head 321 of the front and rear centering mechanism 32 extends to center the front and rear positions of the workpiece, and then the second positioning head 312 of the left and right centering mechanism 31 completes the left and right centering of the workpiece A to be processed under the drive of the oil cylinder. At this time, the first clamping mechanism 21, the second clamping mechanism 22, and the third clamping mechanism 23 are pressed down to complete the clamping of the workpiece A to be processed, and the first positioning head 321 and the second positioning head 312 return to their original positions. After the processing is completed, the first clamping mechanism 21, the second clamping mechanism 22, and the third clamping mechanism 23 are opened, and the auxiliary support head 212 lifts one side of the workpiece for easy removal. The tooling is convenient for assembling the workpiece to be processed and the clamping is firm, which makes the connecting rod processing accuracy higher and is convenient for unloading after processing.
