Referring to fig. 6, in some embodiments, the positioning assembly 20 further includes a first elastic member 23 and a pressing plate 24, the first elastic member 23 is located in the accommodating slot 11, two ends of the first elastic member 23 respectively and elastically abut against the supporting portion 212 and the fixture body 10, and the pressing plate 24 is disposed on the fixture body 10 and abuts against the limiting supporting portion 212.

When the jig 100 positions the workpiece 200, an operator places the workpiece 200 on the jig body 10 by using a mechanical gripper, the two first positioning portions 211 are inserted into the rectangular groove 201, the two first positioning surfaces 2111 respectively abut against two opposite groove walls of the rectangular groove 201, and the first groove wall 2011 abuts against the first positioning portions 211 under the driving of the workpiece 200, so that the first positioning portions 211 move toward a direction close to the jig body 10, that is, move along a negative direction of the Z axis shown in fig. 2, and the first elastic member 23 is compressed onto the jig body 10 by the supporting portions 212. When the jig 100 positions the workpieces 200 of different sizes, that is, the distance between the two first groove walls 2011 is different, the two first groove walls 2011 of the rectangular groove 201 abut against different positions of the first positioning surface 2111, and since the position of the first positioning portion 211 after positioning the workpiece 200 is lower than the initial position, a part of the first positioning portion 211 is accommodated in the accommodating groove 11, and a part of the first positioning surface 2111 is shielded by the jig body 10, the first positioning portion 211 needs to be reset to the initial position, so as to position the subsequent workpiece 200. Therefore, when the jig 100 is positioned, the operator or the robot removes the workpiece 200 from the jig body 10, and the first elastic element 23 provides an elastic force to push the supporting portion 212, so that the first positioning portion 211 is reset to the initial position, so that the first positioning portion 211 can repeatedly position the workpieces 200 of different sizes.
Thus, the first elastic element 23 provides elastic force to push the supporting portion 212, so that the pressed first positioning portion 211 is reset to the initial position under the driving of the supporting portion 212, the fixture 100 can quickly position the workpiece 200, the problem of low positioning accuracy of the workpiece 200 caused by the dimensional tolerance of the workpiece 200 is avoided, and the positioning efficiency is improved. In addition, the pressing plate 24 presses the supporting portion 212 into the accommodating cavity 11, so as to prevent the supporting portion 212 from being separated from the accommodating cavity 11 due to an excessively large moving distance under the driving of the first elastic member 23, so that the supporting portion 212 is always located in the accommodating cavity 11 to stably support the two first positioning portions 211, so that the first positioning portions 211 stably position the workpiece 200, and the positioning stability is improved.
Referring to fig. 5, in some embodiments, a first limiting groove 2122 is further disposed on a side of the supporting portion 212 away from the first positioning portion 211, and one end of the first elastic element 23 is disposed in the first limiting groove 2122.
Thus, the first limiting groove 2122 accommodates part of the first elastic element 23 to limit the position of the first elastic element 23, so as to prevent the first elastic element 23 from shaking when being compressed or reset, so that the first elastic element 23 always provides an elastic force along a direction from the fixture body 10 to the supporting portion 212, that is, along the Z-axis direction shown in fig. 2, so that the supporting portion 212 stably drives the first positioning portion 211 to reset to the initial position, thereby improving the positioning stability. It is understood that the Z-axis direction is a direction in which the jig body 10 points to the first positioning member 21.
Referring to fig. 4 and 5, in some embodiments, the supporting portion 212 further has a second limiting groove 2123, the second limiting groove 2123 is disposed on a side of the supporting portion 212 facing the accommodating groove 11, the fixture body 10 further has a first limiting member 12, the first limiting member 12 is disposed in the accommodating groove 11, the first limiting member 12 is disposed opposite to the supporting portion 212, and the first limiting member 12 is accommodated in the second limiting groove 2123 to limit the supporting portion 212.
Thus, the first limiting member 12 is accommodated in the second limiting groove 2123 to limit the moving path of the supporting portion 212, so that the reciprocating motion path of the supporting portion 212 in the Z-axis direction is the same, the supporting portion 212 always drives the first positioning portion 211 to move up and down along the Z-axis direction, and the first positioning portion 211 is prevented from being displaced along the first direction or the second direction, so that the first positioning portion 211 can stably position the workpiece 200 along the first direction, or the first positioning portion 211 can be accurately reset to the initial position, thereby improving the positioning stability and the positioning accuracy.
In some embodiments, the pressure plate 24 includes a compression portion 241 and a locking portion 242. The pressing portion 241 is disposed on the fixture body 10 and presses the supporting portion 212. The locking portion 242 is inserted into the pressing portion 241 and is screwed to the jig body 10. Illustratively, the locking portion 242 may be a screw.
Therefore, the locking part 242 penetrates through the pressing part 241 and is in threaded connection with the jig body 10, so that the pressing part 241 can be detachably connected with the jig body 10, the pressing part 241 can be replaced conveniently, and the use cost and the maintenance cost are reduced.
In some embodiments, the fixture body 10 is provided with a positioning groove 13, the positioning groove 13 is communicated with the accommodating groove 11, the pressing portion 241 is accommodated in the positioning groove 13, and the locking portion 242 is screwed to the bottom of the positioning groove 13.
In this way, the pressing portion 241 is accommodated in the positioning groove 13, so that the upper surface of the pressing portion 241 is not higher than the upper surface of the jig body 10, thereby preventing the pressing portion 241 from interfering with the workpiece 200 placed on the jig body 10, and improving the detection stability.
In some embodiments, the second positioning member 22 includes a connecting portion 222 and a second positioning portion 223. The connecting portion 222 is disposed through the supporting portion 212 and movably disposed on the fixture body 10. The second positioning portion 223 is connected to the end portion of the connecting portion 222 far from the jig body 10 and disposed between the two first positioning portions 211, the width dimension of the second positioning portion 223 in the second direction is larger than the width dimension of the connecting portion 222, and the second positioning portion 223 further has two second positioning surfaces 221 disposed oppositely to position the workpiece 200 in the second direction.
In this way, the connecting portion 222 is inserted into the supporting portion 212 and movably disposed on the fixture body 10, so that the supporting portion 212 defines a moving path of the connecting portion 222, and the second positioning portion 223 is stable in movement, and can stably position the workpiece 200.
In some embodiments, the positioning assembly 20 further includes a second elastic member 25 and a second retaining member 26. The second elastic member 25 is sleeved on the connecting portion 222, and two ends of the second elastic member 25 respectively abut against the second positioning portion 223 and the jig body 10, and the second limiting member 26 is connected to an end portion of the connecting portion 222 away from the second positioning portion 223 and abuts against one side of the jig body 10 away from the second positioning portion 223 to limit the movement of the second positioning member 22. Exemplarily, the second elastic member 25 may be a spring.
When the jig 100 positions the workpiece 200 having the rectangular groove 201, an operator places the workpiece 200 on the jig body 10 by using a mechanical gripper, the second positioning element 22 is inserted into the rectangular groove 201, the two second positioning surfaces 221 are respectively and accurately abutted against the other two opposite groove walls of the rectangular groove 201, the groove walls of the rectangular groove 201 are driven by the workpiece 200 to abut against the second positioning portion 223, so that the second positioning portion 223 moves toward a direction close to the jig body 10, that is, moves along a negative direction of a Z-axis shown in fig. 2, and the second elastic element 25 is compressed to the jig body 10 by the second positioning portion 223. When the jig 100 positions the workpieces 200 of different size types, that is, the distance between the two second groove walls 2012 is different, the two second groove walls 2012 of the rectangular groove 201 abut against different positions of the second positioning surface 221, and since the position of the second positioner 223 after positioning the workpiece 200 is lower than the initial position, a part of the second positioner 223 is accommodated in the accommodating groove 11, and a part of the second positioning surface 221 is shielded by the jig body 10, the second positioner 223 needs to be reset to the initial position, so as to position the workpieces 200 of different size types. Therefore, when the jig 100 is positioned, the worker or the gripper takes away the workpiece 200, and the second elastic member 25 provides an elastic force to push the second positioning portion 223, so that the second positioning portion 223 is reset to the initial position, thereby facilitating repeated positioning of workpieces 200 of different sizes.
Thus, since the width of the second positioning portion 223 in the second direction is greater than the width of the connecting portion 222, one end of the second elastic member 25 sleeved on the connecting portion 222 abuts against the second positioning portion 223, the other end of the second elastic member 25 abuts against the jig body 10, the second elastic member 25 is limited between the second positioning portion 223 and the jig body 10, and the second elastic member 25 is prevented from being separated from the connecting portion 222, so that the second elastic member 25 stably provides elastic force and pushes the second positioning portion 223, the second positioning portion 223 stably returns to the initial position, and the positioning stability is improved. In addition, the second limiting member 26 is connected to the connecting portion 222 and abuts against the jig body 10, so as to prevent the connecting portion 222 from being separated from the jig body 10 due to an excessively large moving distance, so that the movement of the second positioning member 22 can be limited, and the positioning stability is further improved.
The operation process of the jig 100 is as follows:
firstly, an operator places a workpiece 200 on the jig body 10 by using a mechanical gripper, and the two first positioning portions 211 and the second positioning portions 223 are inserted into the rectangular groove 201;
when the second positioning surface 221 abuts against the second groove wall 2012 and a positioning gap exists between the first positioning surfaces 2111 and the first groove walls 2011, the second positioning surface 221 positions the second groove wall 2012 of the rectangular groove 201 along the second direction, and then the second groove wall 2012 abuts against the second positioning element 22 to move toward the direction close to the jig body 10, and the gap between the two first groove walls 2011 and the two first positioning surfaces 2111 becomes smaller and smaller until the two first positioning surfaces 2111 abut against the corresponding first groove walls 2011 respectively, so that the two first positioning surfaces 2111 position the two first groove walls 2011 of the rectangular groove 201 along the first direction respectively, and the groove walls of the rectangular groove 201 abut against the first positioning portions 211 under the driving of the workpiece 200, so that the first elastic element 23 is compressed onto the jig body 10;
when the first positioning surface 2111 abuts against the first groove wall 2011 and a positioning gap exists between the second positioning surface 221 and the second groove wall 2012, the first positioning surface 2111 positions the two first groove walls 2011 of the rectangular groove 201 along the first direction, then the first groove wall 2011 abuts against the first positioning portion 211 to move towards the direction close to the jig body 10, and the gap between the two second groove walls 2012 and the two second positioning surfaces 221 is smaller and smaller until the two second positioning surfaces 221 abut against the corresponding second groove walls 2012 respectively, so that the two second positioning surfaces 221 position the two second groove walls 2012 of the rectangular groove 201 along the second direction respectively, and the groove walls of the rectangular groove 201 abut against the second positioning portion 223 under the driving of the workpiece 200, so that the second elastic member 25 is compressed onto the jig body 10;
after the positioning is finished, the first elastic element 23 provides an elastic force to push the first supporting portion 212, so that the supporting portion 212 drives the first positioning portion 211 to return to the initial position, and the second elastic element 25 provides an elastic force to push the second positioning portion 223, so that the second positioning portion 223 returns to the initial position.
When the jig 100 positions the workpiece 200, the two first positioning surfaces 2111 position the two opposite groove walls of the rectangular groove 201 along the first direction, and the two second positioning surfaces 221 position the other two opposite groove walls of the rectangular groove 201 along the second direction, so that the rectangular groove 201 can be positioned in the first direction and the second direction at the same time, the workpiece 200 is stably positioned on the jig body 10, and the positioning accuracy is improved.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
