Description
Technical Field
The utility model relates to the technical field of mechanical structures, in particular to a rapid positioning structure used between workpieces.
Background
Many products require multiple machining of the work pieces, for example, the welding of the motor stator requires a positioning structure that is error-proof to achieve proper welding. In most of the conventional positioning structures, as shown in fig. 1, a positioning pin 11 and a pin hole 21 are respectively provided on the joint surface of a fixed workpiece 1 and a movable workpiece 2, and when the movable workpiece 2 is placed on the fixed workpiece 1, the movable workpiece 2 is repeatedly moved to a proper position until the positioning pin 11 is inserted into the pin hole 21. This process is repeated a plurality of times, the positioning pin 11 is difficult to align with the pin hole 21, the positioning operation efficiency between the workpieces is seriously reduced, and the phenomena of misplacement and not-in-place placement of the moving workpieces often occur in the actual production process, so that the processing quality of the workpieces is affected, and the production efficiency is reduced.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a rapid positioning structure for workpieces, which overcomes the defect of blind positioning of the traditional workpieces, realizes rapid visual positioning between the workpieces, greatly improves the positioning operation efficiency between the workpieces, avoids the dislocation phenomenon of workpiece placement and ensures the processing quality of the workpieces.
In order to solve the technical problems, the quick positioning structure for workpieces comprises a fixed workpiece and a movable workpiece, wherein a boss and a pin hole are respectively arranged on the joint surface of the fixed workpiece and the movable workpiece, a long groove is axially formed in the position of the pin hole on the side wall of the fixed workpiece, a positioning hole and a positioning pin are respectively formed in the joint surface of the movable workpiece and the fixed workpiece, a short groove is axially formed in the position of the positioning pin on the side wall of the movable workpiece, and when the movable workpiece is placed on the fixed workpiece, the boss is embedded into the positioning hole, and after the long groove is aligned with the short groove, the positioning pin is inserted into the pin hole.
Further, the boss and the positioning hole are positioned in the center of the joint surface of the fixed workpiece and the movable workpiece.
Because the quick positioning structure for the workpieces adopts the technical scheme, namely the quick positioning structure comprises a fixed workpiece and a movable workpiece, wherein a boss and a pin hole are respectively arranged on the joint surface of the fixed workpiece and the movable workpiece, a long groove is axially formed in the position of the pin hole on the side wall of the fixed workpiece, a positioning hole and a positioning pin are respectively formed in the joint surface of the movable workpiece and the fixed workpiece, a short groove is axially formed in the position of the positioning pin on the side wall of the movable workpiece, and when the movable workpiece is placed on the fixed workpiece, the boss is embedded into the positioning hole, and the positioning pin is inserted into the pin hole after the long groove is aligned with the short groove. The structure overcomes the defect of blind positioning of the traditional workpieces, realizes quick visual positioning between the workpieces, greatly improves the positioning operation efficiency between the workpieces, avoids the dislocation phenomenon of workpiece placement, and ensures the processing quality of the workpieces.
Drawings
The utility model is described in further detail below with reference to the attached drawings and embodiments:
FIG. 1 is a schematic diagram of a conventional workpiece positioning structure;
FIG. 2 is a schematic view of a quick positioning structure for workpieces according to the present utility model.
Detailed Description
As shown in fig. 2, the quick positioning structure for workpieces according to the present utility model comprises a fixed workpiece 1 and a movable workpiece 2, wherein a boss 12 and a pin hole 21 are respectively provided on a joint surface between the fixed workpiece 1 and the movable workpiece 2, a long groove 13 is axially provided on a side wall of the fixed workpiece 1 at a position of the pin hole 21, a positioning hole 22 and a positioning pin 11 are respectively provided on a joint surface between the movable workpiece 2 and the fixed workpiece 1, a short groove 23 is axially provided on a side wall of the movable workpiece 2 at a position of the positioning pin 11, and when the movable workpiece 2 is placed on the fixed workpiece 1, the boss 12 is embedded into the positioning hole 22, and the positioning pin 11 is inserted into the pin hole 21 after the long groove 13 is aligned with the short groove 23.
Preferably, the boss 12 and the positioning hole 22 are located at the center of the joint surface of the fixed workpiece 1 and the movable workpiece 2.
When the structure is used for positioning a fixed workpiece and a movable workpiece, the boss of the fixed workpiece can be directly inserted into the positioning hole of the movable workpiece, and the boss can be conveniently embedded into the positioning hole because the outer diameters of the boss and the positioning hole are relatively large, so that the movable workpiece is rotated at the moment, the short groove is aligned with the long groove, and the positioning pin can be inserted into the pin hole to realize rapid positioning of the fixed workpiece and the movable workpiece. In the structure, the short groove and the long groove form visual positioning, and the defect of blind positioning of the traditional workpiece is overcome.
Claims (2)
