Description

Technical Field

[0001] The utility model relates to the technical field of automobile connecting rod processing, in particular to an automobile connecting rod processing positioning device. Background Art

[0002] The automobile connecting rod is an important part of the automobile. The function of the automobile connecting rod is to transmit the force borne by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The two ends of the automobile connecting rod mechanism are respectively hinged with the active and driven components to transmit motion and force. For example, in reciprocating piston power machinery and compressors, connecting rods are used to connect the piston and the crank. Connecting rods are mostly steel parts, and the cross-section of the main part is mostly circular or I-shaped. There are holes at both ends, and bronze bushings or needle bearings are installed in the holes for inserting axle pins to form a hinge. The connecting rod is an important part in the automobile engine. It connects the piston and the crankshaft, and its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft.

[0003] Common automobile connecting rod processing and positioning devices cannot slightly adjust the inclination angle of the clamping plate through changes in the surface of the connecting rod, so that the clamping force of the clamping plate is concentrated on a point on the workpiece surface. The workpiece is deformed due to excessive local pressure, especially when clamping thin-walled, soft materials or precision parts. Common automobile connecting rod processing and positioning devices cannot allow the workpiece to move or adjust freely within a certain range when positioning the automobile connecting rod, and cannot compensate for changes in the geometric shape of the workpiece or manufacturing tolerances, making it impossible to achieve precise clamping when the workpiece size changes slightly.

[0004] Therefore, for the above-mentioned automobile connecting rod processing and positioning devices, it is impossible to move or adjust the workpiece freely within a certain range, which means that they cannot effectively compensate for changes in the geometric shape of the workpiece or manufacturing tolerances. When the size of the workpiece changes slightly, precise clamping may not be achieved. Due to the lack of responsiveness to changes in the connecting rod surface, the clamping plate of the traditional clamping device cannot fine-tune its inclination angle according to the actual situation of the workpiece, resulting in the clamping force being concentrated at one point on the workpiece surface rather than being evenly distributed. This may cause excessive local pressure, especially for thin-walled, soft materials or precision parts, which can easily cause deformation of the workpiece, and urgently needs to be solved to improve the use scenarios of automobile connecting rod processing and positioning devices. Utility Model Content

[0005] In order to overcome the problem of workpiece deformation caused by excessive local pressure, the common automobile connecting rod processing positioning device cannot slightly adjust the inclination angle of the clamping plate according to the surface change of the connecting rod, so that the clamping force of the clamping plate is concentrated on a point on the workpiece surface. The common automobile connecting rod processing positioning device cannot make the workpiece move or adjust freely within a certain range when positioning the automobile connecting rod, and cannot compensate for the geometric shape change or manufacturing tolerance of the workpiece, so that precise clamping cannot be achieved when the workpiece size changes slightly.

By setting sliding assemblies, driving assemblies, floating assemblies, connecting rod positioning plates and other structures, the connecting rod is allowed to move or adjust freely within a certain range when limiting and positioning the connecting rod.
