In some embodiments, the above-described feature drive mechanism 31 may be configured as shown in fig. 4 and 5. Referring to fig. 4 and 5, one of the driving mechanisms 31 includes a lead screw 311, a nut 312 screwed with the lead screw 311, and a driving member 313 for driving the lead screw 311, and the mounting base 2 is further provided with a first guide rail 314 extending in a transverse direction, and the clamping end 32 connected with the driving mechanism 31 is connected with the nut 312 and is in sliding fit with the first guide rail 314.
The two driving mechanisms 31 positioned at the two sides of the workpiece 6 to be clamped are respectively used for positioning and clamping the workpiece 6 to be clamped, and the driving mechanism 31 used for positioning the workpiece 6 to be clamped is in a matching mode of a lead screw 311 and a nut 312, so that the driving of the clamping end 32 connected with the driving mechanism is realized. The clamping end 32 can be driven by the nut 312 to move to a preset position, so that the positioning of one side surface of the workpiece 6 to be clamped is realized. Aiming at workpieces 6 to be clamped with different width sizes, the workpieces need to be positioned at different positions, and the driving mechanism 31 correspondingly pushes the position of the clamping end 32 according to parameters in a preset program, so that the positioning accuracy is ensured. On the premise that the driving mechanism 31 positions one side surface of the workpiece 6 to be clamped, the driving mechanism 31 positioned on the other side of the workpiece 6 to be clamped is close to the workpiece 6 to be clamped along the transverse direction, the workpiece 6 to be clamped is clamped by the aid of the clamping end 32 of the driving mechanism 31, so that the workpiece 6 to be clamped is reliably clamped between the two driving mechanisms 31, and a subsequent welding and polishing robot polishes the preset position of the workpiece 6 to be clamped.
The driving mode of the screw pair has the advantage of high positioning precision, in order to guarantee the accuracy of the position of the workpiece 6 to be clamped, the driving piece 313 is utilized to drive the screw 311 to rotate, then the linear driving on the clamping end 32 is realized through the matching of the screw 311 and the nut 312, the positioning surface of the workpiece 6 to be clamped can be effectively limited, the position precision of the workpiece 6 to be clamped is guaranteed, and the polishing quality of a subsequent welding polishing robot is improved.
In addition, the driving mode of the screw pair also has the advantages of simple structure, low cost and the like, and can effectively transmit axial force and realize stable and smooth driving effect. Under the driving action of the screw pair, the sliding fit between the clamping end 32 and the first guide rail 314 effectively limits the moving direction of the clamping end 32, so that the clamping end 32 can accurately move along the transverse direction, and the outer end face is utilized to effectively position the side face of the workpiece 6 to be clamped.
If the workpiece 6 to be clamped is a strip-shaped asymmetric component, in order to ensure the safety and stability of the operation of the positioner during transverse positioning and clamping, the gravity center of the workpiece 6 to be clamped and the rotation axis of the rotation end of the positioner are ensured to be in the same plane as much as possible. At this time, the two driving mechanisms 31 limit the lateral positions of both sides of the end portion of the workpiece 6 to be clamped, so that the center of the workpiece 6 to be clamped can be limited to a desired position.
In some embodiments, the above-described feature of the drive mechanism 31 may be configured as shown in FIG. 4. Referring to fig. 4, the driving mechanism 31 on the other side of the positioning side of the workpiece 6 to be clamped is a linear hydraulic cylinder, the mounting base 2 is provided with a second guide rail 315 extending in the transverse direction, and the clamping end 32 is connected with the linear hydraulic cylinder and is in sliding fit with the second guide rail 315.
In this embodiment, the linear hydraulic cylinder is used to drive the clamping ends 32 to move towards the side close to the workpiece 6 to be clamped, so as to clamp the workpiece 6 to be clamped, and the two side surfaces of the workpiece 6 to be clamped are respectively abutted against the two clamping ends 32, thereby achieving a reliable clamping effect. The linear hydraulic cylinder has the characteristics of high transmission power, low speed and stability, and can drive the clamping end 32 to stably act to clamp the workpiece 6 to be clamped. The structure is convenient to arrange on the premise of meeting the driving action, and the occupation of the space can be reduced.
The second guide rail 315 is arranged on the mounting base 2, and is used for limiting the moving direction of the clamping end 32, so that the clamping end 32 can move transversely and accurately and is pressed on the other side surface of the workpiece 6 to be clamped, and scraping damage to the workpiece 6 to be clamped caused by angle deflection in the moving process of the clamping end 32 is avoided.

The sliding piece 41 can move along the longitudinal direction until the side surface of the sliding piece is in contact with and pressed against the outer end surface of the workpiece 6 to be clamped, so that the longitudinal position of the workpiece 6 to be clamped is limited. The corner cylinder 42 drives the upper lower pressing plate 46 to rotate or lift. The lower pressing plate 46 extends towards the periphery of the corner oil cylinder 42, and when the workpiece 6 to be clamped is pressed by the lower pressing plate 46, the corner oil cylinder 42 can effectively avoid the workpiece 6 to be clamped. When the corner oil cylinder 42 is contracted, the lower pressing plate 46 can be driven to move downwards to abut against the top surface of the end part of the workpiece 6 to be clamped, so that vertical limiting of the workpiece 6 to be clamped is formed, and the workpiece 6 to be clamped is reliably locked on the positioning platform 1.

After the workpiece 6 to be clamped is placed on the positioning platform 1, the workpiece 6 to be clamped is transversely positioned by using one of the clamping ends 32, and the transverse position of the workpiece 6 to be clamped is limited by matching the clamping action of the other clamping end 32. Then, the linear driving mechanism 45 drives the sliding member 41 to move to a side close to the outer end face of the workpiece 6 to be clamped until the side face of the sliding member 41 is abutted against the outer end face of the workpiece 6 to be clamped, so as to limit the longitudinal position of the workpiece 6 to be clamped. And then, the output end of the corner oil cylinder 42 rotates to drive the lower pressing plate 46 to rotate to the position above the end part of the workpiece 6 to be clamped, and finally, the output end of the corner oil cylinder 42 retracts to drive the lower pressing plate 46 to press down on the top surface of the end part of the workpiece 6 to be clamped, so that the workpiece 6 to be clamped is vertically pressed, and the vertical limiting effect is achieved.
