Description

TECHNICAL FIELD

[0001] The present application relates to the positioning technical field, and particularly to a floating positioning device. BACKGROUND

[0002] At present, modern stamping production has basically realized automation. When the parts are transmitted between die processes in the automatic production, the position needs to be accurate, and the die positioning requirement is high.

[0003] In the prior art, when the part needs to be flanged, the upper die cutter corresponding to the positioning device needs to be hollowed out to realize the avoidance of the positioning device. However, after the upper die is hollowed out, the wall thickness is relatively thin, and the strength is insufficient. Moreover, the hollow design also causes the adjustable range of the positioning to be small, which is not conducive to the adjustment in the later period.

[0004] Therefore, how to position the part while avoiding insufficient strength of the upper die becomes a problem to be solved. CONTENT OF THE UTILITY MODEL

[0042] As shown in Figures 1 to 4 The present application provides a floating positioning device 1, comprising:

[0043] A positioning member 11;

[0044] A mounting plate 12, the first side of the mounting plate 12 is vertically connected with the positioning member 11, and the surface of the first side of the mounting plate 12 is used to be pressed by a driving rod 2;

[0045] A reset assembly 13, the reset assembly 13 is arranged on the second side of the mounting plate 12 and connected with the mounting plate 12, and is used to drive the mounting plate 12 to return to the initial position in the case that the surface of the first side of the mounting plate 12 is not pressed by the driving rod 2;

[0046] A rotation prevention assembly 14, the rotation prevention assembly 14 is locked on the outer periphery of the reset assembly 13.

[0047] In this embodiment, the positioning member 11 is a plate-shaped structure perpendicular to the mounting plate 12, the positioning member 11 is matched with the edge of the part 4, so as to abut against the outer edge of the part 4 to realize the positioning of the part 4. The surface of the first side of the mounting plate 12 is a plate-shaped structure, so as to facilitate the pressing of the surface of the first side of the mounting plate 12 by the driving rod 2, and a long circular hole is arranged on the mounting plate 12, so as to facilitate the fixing of the position of the mounting plate 12 after the adjustment of the position of the part, and the pin can be inserted into the long circular hole to fix the mounting plate 12.

[0048] The floating positioning device 1 provided by the embodiment of the present application comprises a positioning member 11, a mounting plate 12, a reset assembly 13 and an anti-rotation assembly 14. The mounting plate 12 has a first side and a second side. The first side of the mounting plate 12 is provided with the positioning member 11 which is connected perpendicularly to the mounting plate 12. The second side of the mounting plate 12 is connected with the reset assembly 13. When the edge processing of the part 4 is needed, the part 4 is placed in the mold cavity, and then the positioning member 11 is abutted against the edge of the part 4 outside the mold cavity. The downward movement of the upper die 3 is used to press the driving rod 2 downward to the first surface of the mounting plate 12, so that the positioning member 11 connected perpendicularly to the first side of the mounting plate 12 moves downward, thereby the upper die 3 does not need to be designed to be hollowed out to avoid the positioning member 11, and the problem that the upper die 3 needs to be hollowed out is solved. During the downward movement of the floating positioning device 1, the positioning member 11 connected perpendicularly to the first side of the mounting plate 12 can always abut against the part 4, thereby guaranteeing the positioning of the part 4. The downward movement of the upper die 3 can realize the pressing of the part 4 in the area outside the mold cavity, so as to realize the edge processing of the part 4. Moreover, during the downward movement of the floating positioning device 1, the reset assembly 13 connected with the mounting plate 12 is peripherally locked with the anti-rotation assembly 14, thereby avoiding the rotation of the reset assembly 13, the mounting plate 12 and the positioning member 11, and the reset assembly can be fixed, thereby guaranteeing the continuous positioning of the part 4 by the positioning member 11, and avoiding the problem of positioning failure. After the edge processing of the part 4 is completed, the reset assembly 13 can restore the mounting plate 12 and the positioning member 11 connected with the mounting plate 12 to the initial position after the upper die 3 no longer presses the mounting plate 12 through the driving rod 2, thereby realizing the reset.

[0049] Therefore, the floating positioning device 1 provided by the present application avoids the hollowed-out design of the upper die 3 to the positioning member 11 connected to the mounting plate 12 through the pressing of the mounting plate 12 by the driving rod 2, thereby avoiding the problem of insufficient strength caused by the thin wall thickness of the upper die 3, improving the strength of the upper die 3, and guaranteeing the edge processing of the part 4 by the upper die 3. Meanwhile, the position of the positioning plate can be adjusted according to the edge processing requirement of the part 4 without hollowing out the position of the positioning plate on the upper die 3, thereby meeting more requirements of users.

[0050] As shown in the embodiment of the present application, it further comprises: Figures 1 to 4

[0051] an outer sleeve 15 which is sleeved outside the reset assembly 13. The reset assembly 13 is movable relative to the outer sleeve 15 in the axial direction. The top of the reset assembly 13 is movable between a preset distance higher than the top of the outer sleeve 15 and flush with the top of the outer sleeve 15. The anti-rotation assembly 14 is locked peripherally outside the reset assembly 13 through the outer sleeve 15. ​

[0052] In this embodiment, the outer sleeve 15 is a cylindrical structure, which is sleeved outside the reset assembly 13. The inner wall of the outer sleeve 15 at least partially contacts the outer wall of the reset assembly 13, so that the outer sleeve 15 can support the reset assembly 13, and the reset assembly 13 can slide axially and rotate circumferentially relative to the outer sleeve 15. The bottom of the outer sleeve 15 is provided with a base 16, which can be integrally formed with the outer sleeve 15 or separately arranged.

[0053] In this embodiment, the floating positioning device 1 comprises a positioning piece 11, a mounting plate 12, a reset assembly 13, an anti-rotation assembly 14 and an outer sleeve 15. The reset assembly 13 is arranged in the outer sleeve 15, and can move axially relative to the outer sleeve 15, i.e. the reset assembly 13 is not fixedly connected with the outer sleeve 15, and the outer sleeve 15 is sleeved outside part of the reset assembly 13. In the initial state, the reset assembly 13 at least partially protrudes out of the outer sleeve 15, i.e. the top of the reset assembly 13 is higher than the top of the outer sleeve 15 by a predetermined distance. After the upper die 3 is pressed against the mounting plate 12 by the rod press, the reset assembly 13 can move axially downward relative to the outer sleeve 15, so that the reset assembly 13 can move at most to a position where the top is flush with the mounting plate 12, and the anti-rotation assembly 14 is locked on the outer periphery of the reset assembly 13 through the outer sleeve 15, so as to avoid rotation of the reset assembly 13, thereby avoiding deviation of the position of the positioning piece 11, and improving the positioning accuracy. The arrangement of the outer sleeve 15 enables the floating positioning device 1 to have a movement stroke, so that the mounting plate 12 and the positioning piece 11 can move in the area of the movement stroke. After the upper die 3 no longer presses the mounting plate 12 by the driving rod 2, the reset assembly 13 can drive the mounting plate 12 and the positioning piece 11 to return to the initial position, so that the floating positioning device 1 can position and flange the next part 4.

[0054] As shown in the drawings, Figures 1 to 4 In the embodiment of the present application, the reset assembly 13 comprises:

[0055] an inner sleeve 131, which is sleeved in the outer sleeve 15 and moves axially relative to the outer sleeve 15. The top of the inner sleeve 131 is fixedly connected with the mounting plate 12, and the bottom of the inner sleeve 131 has at least a communication hole;

[0056] a resilient member 132, which is arranged at least in the inner sleeve 131. The first end of the resilient member 132 is connected with the inner top surface of the inner sleeve 131, and the second end of the resilient member 132 is connected with the inner bottom surface of the outer sleeve 15 through the communication hole.

[0057] In this embodiment, the inner wall of the inner sleeve 131 is at least partially curved to match the outer sleeve 15, so that the inner sleeve 131 can slide axially or rotate circumferentially relative to the outer sleeve 15. The communication hole at the bottom of the inner sleeve 131 can match the cross section of the elastic member 132, so that the elastic member 132 can pass through the communication hole, or the area of the communication hole is equal to the area of the bottom surface of the inner sleeve 131, that is, the bottom surface of the inner sleeve 131 is entirely penetrated. The elastic member 132 can be a spring or other elastic structure, as long as it is suitable for production and application, which is not limited here.

[0058] In this embodiment, the floating positioning device 1 includes a positioning member 11, a mounting plate 12, a reset assembly 13, an anti-rotation assembly 14, and an outer sleeve 15. The reset assembly 13 includes an inner sleeve 131 and an elastic member 132. The top surface of the inner sleeve 131 is fixedly connected to the mounting plate 12. The inner sleeve 131 is arranged in the outer sleeve 15 and can move axially relative to the outer sleeve 15. The bottom of the inner sleeve 131 has a communication hole to realize the communication between the inner sleeve 131 and the outer sleeve 15. The elastic member 132 connects the inner sleeve 131 and the outer sleeve 15 by passing through the communication hole. The elastic member 132 is arranged in the inner sleeve 131. The first end of the elastic member 132 is connected to the inner top surface of the inner sleeve 131. The second end of the elastic member 132 passes through the communication hole and is connected to the inner bottom surface of the outer sleeve 15. After the upper die 3 is pressed against the mounting plate 12 by the rod press, the inner sleeve 131 moves axially downward relative to the outer sleeve 15 under the action of the mounting plate 12. The bottom of the inner sleeve 131 is arranged close to the bottom of the outer sleeve 15, and the elastic member 132 is compressed by the inner sleeve 131. After the upper die 3 no longer presses the mounting plate 12 by the rod press, the compressed elastic member 132 increases the elastic force upward to restore the natural state, thereby driving the inner sleeve 131 connected to the first end of the elastic member 132 to move upward, so that the inner sleeve 131 and the mounting plate 12 connected to the inner sleeve 131 can restore to the initial state, to realize the reset of the mounting plate 12 and the positioning member 11.

[0059] As shown in Figures 1 to 4 In the embodiment of the present application, the projection of the mounting plate 12 along the axial direction at least covers the outer sleeve 15.

[0060] In this embodiment, when the pressing force of the upper die 3 on the mounting plate 12 by the driving rod 2 is too large, the mounting plate 12 will not enter the outer sleeve 15, and the mounting plate 12 can always be at the top of the outer sleeve 15, so that the positioning member 11 connected to the first side surface of the mounting plate 12 can always position the part 4, avoiding the problem of positioning failure.

[0061] In the embodiment of the present application, in the initial state, the bottom of the inner sleeve 131 is at a preset distance from the bottom surface of the outer sleeve 15, and the top surface of the inner sleeve 131 is at a preset distance above the top surface of the outer sleeve 15.

[0062] In this embodiment, the preset distance is the maximum movement distance of the mounting plate 12 and the positioning plate. After the upper die 3 is pressed against the mounting plate 12 by the driving rod 2, the mounting plate 12 and the positioning plate can move downward by the preset distance at most, so that the upper die 3 can move downward by the preset distance to realize the flanging operation of the upper die 3 on the part 4. After the mounting plate 12 and the positioning plate move downward by the preset distance, the bottom of the inner sleeve 131 is in contact with the bottom of the outer sleeve 15, and the bottom of the inner sleeve 131 is flush with the bottom of the outer sleeve 15. The elastic member 132 changes from the natural state to the compressed state, and the mounting plate 12 is located above the inner sleeve 131 and the outer sleeve 15. After the upper die 3 is no longer pressed against the mounting plate 12 by the driving rod 2, the elastic member 132 in the compressed state moves upward to restore the natural state, thereby driving the inner sleeve 131, the mounting plate 12 and the positioning member 11 to reset.

[0063] As shown in Figures 1 to 4 In the embodiment of the present application, the outer wall of the inner sleeve 131 has a first surface 1311, a second surface 1312, a third surface and a fourth surface arranged in sequence. The first surface 1311 is opposite to the third surface, and the second surface 1312 is opposite to the fourth surface. The first surface 1311 and the third surface are both flat surfaces, and the second surface 1312 and the fourth surface are both curved surfaces matched with the inner wall of the outer sleeve 15. The anti-rotation assembly 14 is locked on the outer periphery of the first surface 1311 and / or the third surface of the inner sleeve 131.

[0064] In this embodiment, the inner sleeve 131 is formed by cutting a cylindrical structure along the axial direction. The two circular arc-shaped protrusions on the opposite sides of the cylindrical structure are cut to form the first surface 1311 and the third surface. The original surfaces of the cylindrical structure are the second surface 1312 and the fourth surface. The second surface 1312 and the fourth surface are matched with and attached to the inner wall of the outer sleeve 15, so as to facilitate the sliding of the inner sleeve 131 relative to the outer sleeve 15 along the axial direction. The first surface 1311 and the third surface are flat surfaces, so as to avoid the rotation of the inner sleeve 131 relative to the outer sleeve 15. The flat first surface 1311 and the third surface are arranged to facilitate the locking of the anti-rotation device on the inner sleeve 131, further avoiding the rotation of the inner sleeve 131 relative to the outer sleeve 15, thereby avoiding the position deviation of the positioning member 11 connected to the inner sleeve 131, and ensuring the accuracy of the positioning.

[0065] As shown in Figures 1 to 4As shown, in the embodiment of the present application, the anti-rotation assembly 14 comprises two detachably connected semi-circular anti-rotation buckles 141, which enclose and lock the inner sleeve 131. The inner wall of each anti-rotation buckle 141 has a planar connecting surface matching the corresponding first surface 1311 or third surface.

[0066] In this embodiment, the anti-rotation buckle 141 has an outer circle and inner square structure, i.e., the outer wall of the anti-rotation buckle 141 is a semi-circular structure, and the inner wall is a planar structure matching the first surface 1311 or the third surface. The anti-rotation buckle 141 can be made of metal to improve the locking strength. The two anti-rotation buckles 141 can be detachably connected by bolts.

[0067] In this embodiment, the anti-rotation assembly 14 comprises two anti-rotation buckles 141, each of which is a semi-circular structure. The two anti-rotation buckles 141 form a circular structure for locking around the outer periphery of the inner sleeve 131. The inner wall of each anti-rotation buckle 141 has a connecting surface matching the first surface 1311 or the third surface, so that the two anti-rotation buckles 141 are in contact with and abut against the first surface 1311 and the third surface of the inner sleeve 131, respectively. Then, the two ends of the two anti-rotation buckles 141 are connected by bolts, thereby locking the inner sleeve 131, connecting the inner sleeve 131 with the outer sleeve 15, further fixing the inner sleeve 131 with the outer sleeve 15, and preventing the inner sleeve 131 from rotating relative to the outer sleeve 15.

[0068] In the embodiment of the present application, the side wall of the outer sleeve 15 is provided with two connecting grooves 151 extending through the outer sleeve 15. The two connecting grooves 151 are respectively arranged corresponding to the first surface 1311 and the third surface. Each connecting groove 151 is matched with the anti-rotation buckle 141, so that each anti-rotation buckle 141 at least partially extends into the connecting groove 151 to lock the inner sleeve 131.

[0069] In this embodiment, the inner sleeve 131 is sleeved with the outer sleeve 15, and the outer sleeve 15 is provided with two anti-rotation buckles 141. The side wall of the outer sleeve 15 is provided with two oppositely arranged connecting grooves 151. The two connecting grooves 151 are respectively arranged opposite to the first surface 1311 and the third surface of the inner sleeve 131. The anti-rotation buckle 141 at least partially extends into the connecting groove 151 to fit with the first surface 1311 or the third surface of the inner sleeve 131. After the two anti-rotation buckles 141 are connected, the inner sleeve 131 can be locked, and the connection between the inner sleeve 131 and the outer sleeve 15 can be further achieved.

[0070] As Figures 1 to 4As shown in this embodiment, an exhaust hole 1313 is provided on the first region of the side wall of the inner sleeve 131;

[0071] In its initial state, the first region protrudes from the outer sleeve 15.

[0072] In this embodiment, the inner sleeve 131 has a first region and a second region. In the initial state, the first region protrudes outside the outer sleeve 15, that is, it is higher than the outer sleeve 15. The second region coincides with the outer sleeve 15, that is, it is fitted inside the outer sleeve 15. The first region is provided with an exhaust hole 1313, which allows the air inside the inner sleeve 131 to be discharged through the exhaust hole 1313. This avoids the problems of reduced air pressure, inconvenient installation, and inability to disassemble caused by the inability to discharge air inside the inner sleeve 131. Thus, the exhaust hole 1313 makes it convenient to assemble and disassemble the inner sleeve 131 and the outer sleeve 15.

[0073] like Figures 1 to 4 As shown in the embodiment of this application, the positioning member 11 is fixedly disposed on the edge of the first side of the mounting plate 12; or

[0074] The positioning element 11 is movably connected to the first side of the mounting plate 12.

[0075] In one embodiment of this application, the positioning element 11 can be fixedly disposed on the edge of the first side surface of the mounting plate 12 to position the part 4. The position of the entire floating positioning device 1 can also be adjusted according to the positioning requirements of the part 4 to change the position of the positioning element 11, thereby changing the positioning position of the part 4. The positioning element 11 and the mounting plate 12 can be integrally formed, thereby reducing costs and facilitating production; alternatively, the positioning element 11 and the mounting plate 12 can be separately disposed.

[0076] In another embodiment of this application, the positioning member 11 is movably connected to the first side surface of the mounting plate 12. The movable connection can be a sliding connection or other connection methods. Thus, the position of the positioning member 11 on the mounting plate 12 can be adjusted according to the positioning requirements of the part 4, so that the position of the positioning member 11 can be adjusted without adjusting the position of the entire floating positioning device 1, making position adjustment simpler and more convenient.

[0077] In this embodiment, the mounting plate 12 also includes a locking fastener, which can detachably connect the positioning member 11 to the mounting plate 12. After the positioning member 11 is adjusted to the appropriate position, the locking fastener fixes the positioning member 11 to the mounting plate 12.
