[0035] In order to more clearly understand the embodiments of the present application, the following Figures 1 to 6 The embodiments of the present application are described in detail.

[0036] like Figures 1 to 4 As shown, the present application provides a floating positioning device 1 on one hand, and the floating positioning device 1 includes a first positioning mechanism 11, a second positioning mechanism 12 and a floating mechanism 13. The first positioning mechanism 11 includes a first positioning member 111; the second positioning mechanism 12 includes a second positioning member 121, and the second positioning member 121 is arranged in cooperation with the first positioning member 111; the floating mechanism 13 includes a first moving part 131 arranged along a first direction X and a second moving part 132 arranged along a second direction Y, the first direction X and the second direction Y are arranged to intersect, the first moving part 131 is arranged on one side of the second moving part 132, and the first positioning mechanism 11 or the second positioning mechanism 12 is arranged on the side of the second moving part 132 away from the first moving part 131.

[0037] The second positioning member 121 can be arranged in cooperation with the first positioning member 111, and the first positioning member 111 can be a convex part, and the second positioning member 121 can be a concave part that cooperates with the convex part, and the convex part is accommodated in the concave part during positioning, thereby achieving positioning. Alternatively, the first positioning member 111 can be a concave part, and the second positioning member 121 can be a convex part that cooperates with the concave part, and the positioning function can also be achieved. The moving part refers to a component that can move linearly, such as a gear rack mechanism, a guide rail slider mechanism, etc.

[0038] The first moving part 131 arranged along the first direction X means that the first moving part 131 can move along the first direction X, and similarly, the second moving part 132 arranged along the second direction Y means that the second moving part 132 can move along the second direction Y. The first direction X and the second direction Y are arranged to intersect each other, which means that the angle formed between the first direction X and the second direction Y can be any angle except 0° and 180°.

[0039] The first positioning mechanism 11 or the second positioning mechanism 12 is arranged on the side of the second movable part 132 away from the first movable part 131, which means that the first positioning mechanism 11 can be arranged on the side of the second movable part 132 away from the first movable part 131, so that the floating mechanism 13 drives the first positioning mechanism 11 to move when floating to achieve the alignment and positioning of the first positioning member 111 and the second positioning member 121. The second positioning mechanism 12 can also be arranged on the side of the second movable part 132 away from the first movable part 131, so that the floating mechanism 13 drives the second positioning mechanism 12 to move when floating to achieve the alignment and positioning of the second positioning member 112 and the first positioning member 111.

[0040] When there are manufacturing errors, installation errors and other errors, the first positioning member 111 and the second positioning member 121 cannot accommodate and cooperate with each other and lose the positioning function. By arranging the first moving part 131 along the first direction X and the second moving part 132 along the second direction Y on the floating mechanism 13, and then arranging the first positioning mechanism 11 or the second positioning mechanism 12 on the side of the second moving part 132 away from the first moving part 131, the first positioning mechanism 11 or the second positioning mechanism 12 can move in the first direction X and the second direction Y, and then the first positioning member 11 or the second positioning member 12 can float in the first direction X and the second direction Y to ensure that the two can accommodate and cooperate with each other, thereby ensuring the positioning accuracy of the positioning device.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments, the floating mechanism 13 further includes a floating member 133 , the floating member 133 includes a first surface 1331 and a second surface 1332 arranged opposite to each other, the first surface 1331 is connected to the first moving portion 131 , and the second surface 1332 is connected to the second moving portion 132 .

[0042] The connection between the first surface 1331 and the first moving part 131 can be a detachable connection such as bolt connection and plug connection to increase interchangeability, or a non-detachable connection such as welding and adhesive connection to improve stability, and the present application does not limit this. Similarly, the connection between the second surface 1332 and the second moving part 132 can also be a detachable connection or a non-detachable connection, and the present application does not limit this.

[0043] By setting up the floating part 133, the first movable part 131 and the second movable part 132 can be connected, and the movement of the first movable part 131 along the first direction X can be transmitted to the second movable part 132. Combined with the movement of the second movable part 132 along the second direction Y, the first positioning mechanism 11 or the second positioning mechanism 12 connected to the second movable part 132 can be moved in both the first direction X and the second direction Y, thereby realizing floating positioning.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the first moving portion 131 includes a first guide rail 1311 and a first slider 1312 , the first guide rail 1311 is arranged along the first direction X; the first slider 1312 is slidably arranged on the first guide rail 1311 ; the first surface 1331 is connected to the first guide rail 1311 or the first slider 1312 .

[0045] When the first surface 1331 is connected to the first guide rail 1311, the first surface 1331 and the first guide rail 1311 can be manufactured as an integral part, for example, the first surface 1331 protrudes outward to form the first guide rail 1311, so as to reduce the processing steps and improve the connection stability between the two; the first surface 1331 and the first guide rail 1311 can also be manufactured separately and then assembled together. At this time, the connection method between the two can be a detachable connection method such as bolt connection and plug-in, or a non-detachable connection method such as welding and gluing, and the present application does not impose any restrictions on this.

[0046] Similarly, when the first surface 1331 is connected to the first slider 1312, the first surface 1331 and the first guide slider 1312 can be manufactured as one piece, for example, the first surface 1331 is recessed inward to form the first slider 1312 to reduce the processing steps and improve the connection stability between the two; the first surface 1331 and the first slider 1312 can also be manufactured separately and then assembled together. At this time, the connection method between the two can be a detachable connection method such as bolt connection and plug-in, or a non-detachable connection method such as welding and gluing, and the present application does not impose any restrictions on this.

[0047] The first slider 1311 is slidably arranged on the first guide rail 1312 to realize the movement function of the first moving part along the first direction X. The structure is simple and occupies a small space, which can reduce the volume of the floating positioning device.

[0048] like Figure 3 and Figure 4 As shown, in some embodiments, the second movable portion 132 includes a second guide rail 1321 and a second slider 1322 , the second guide rail 1321 is arranged along the second direction Y; the second slider 1322 is slidably arranged on the second guide rail 1321 ; the second surface 1332 is connected to the second guide rail 1321 or the second slider 1322 .

[0049] When the second surface 1332 is connected to the second guide rail 1321, the second surface 1332 and the second guide rail 1321 can be manufactured as an integral part, for example, the second surface 1332 protrudes outward to form the second guide rail 1321, so as to reduce the processing steps and improve the connection stability between the two; the second surface 1332 and the second guide rail 1321 can also be manufactured separately and then assembled together. At this time, the connection method between the two can be a detachable connection method such as bolt connection and plug-in, or a non-detachable connection method such as welding and gluing, and the present application does not impose any restrictions on this.

[0050] Similarly, when the second surface 1332 is connected to the second slider 1322, the second surface 1332 and the second guide slider 1322 can be manufactured as one piece, for example, the second surface 1332 is recessed inward to form the second slider 1322 to reduce the processing steps and improve the connection stability between the two; the second surface 1332 and the second slider 1322 can also be manufactured separately and then assembled together. At this time, the connection method between the two can be a detachable connection method such as bolt connection and plug-in, or a non-detachable connection method such as welding and gluing, and the present application does not impose any restrictions on this.

[0051] The second moving part can move along the second direction Y by slidably setting the second slider 1321 on the second guide rail 1322. The structure is simple and occupies little space, which can reduce the volume of the floating positioning device.

[0052] In some embodiments, the first moving part 131 and the second moving part 132 may also be a gear rack mechanism, wherein two racks are respectively arranged along the first direction X and the second direction Y, and the floating mechanism is driven by the gears to move along the first direction X and the second direction Y.

[0053] In some embodiments, the first moving part 131 and the second moving part 132 may also be a combination of a gear rack mechanism and a guide rail slider mechanism, that is, one of the first moving part 131 and the second moving part 132 is a gear rack mechanism and the other is a guide rail slider mechanism.

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, the floating positioning device 1 further includes a mounting member 134 , which is disposed on a side of the second movable portion 132 away from the floating member 133 , and the first positioning mechanism 11 or the second positioning mechanism 12 is connected to the second movable portion 132 via the mounting member 134 .

[0055] The mounting member 134 is disposed on the side of the second moving part 132 away from the floating member 133, that is, the mounting member 134 and the floating member 133 are respectively disposed on two relatively movable parts of the second moving part 132, so as to ensure that the mounting member 134 can move relative to the floating member 133. For example, when the second moving part 132 is a guide rail and slider mechanism, the mounting member 134 and the floating member 133 are respectively disposed on the second guide rail 1321 and the second slider 1322; similarly, when the second moving part 132 is a gear rack mechanism, the mounting member 134 and the floating member 133 are respectively disposed on the gear and the rack.

[0056] The mounting member 134 and the first positioning mechanism 11 or the second positioning mechanism 12 can be manufactured as one piece or can be manufactured separately and then assembled. When manufactured separately, they can be connected in a detachable connection or a non-detachable connection, and the present application does not impose any limitation on this.

[0057] By setting the mounting member 134, the first positioning mechanism 11 or the second positioning mechanism 12 can be connected, and the movement of the second movable part 132 along the second direction Y can be transmitted to the first positioning mechanism 11 or the second positioning mechanism 12 connected to the second movable part 132, thereby realizing the floating positioning of the floating positioning device 1.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, the floating mechanism 13 further includes a fixing member 135 , and the fixing member 135 is disposed on a side of the first moving portion 131 away from the floating member 133 .

[0059] The fixing member 135 is a component fixedly connected to the frame. The fixing member 135 is arranged on the side of the first moving part 131 away from the floating member 133, that is, the fixing member 135 and the floating member 133 are respectively arranged on two relatively movable parts of the first moving part 131 to ensure that the floating member 133 can move relative to the fixing member 135. For example, when the first moving part 131 is a guide rail and slider mechanism, the fixing member 135 and the floating member 133 are respectively arranged on the first guide rail 1311 and the first slider 1312; similarly, when the first moving part 131 is a gear rack mechanism, the fixing member 135 and the floating member 133 are respectively arranged on the gear and the rack.

[0060] By setting a fixing member 135 to fix the component connected to the fixing member 135 on the first moving mechanism 131, the floating member 133 has a determined direction of movement relative to the first moving part 131, and then through the connection between the floating member 133 and the second moving part 132, the first positioning mechanism 11 or the second positioning mechanism 12 connected to the second moving part 132 finally has a determined moving direction, which is convenient for adjusting the moving direction of the first positioning member 111 or the second positioning member 121, thereby realizing the floating positioning of the floating positioning device 1.

[0061] like Figure 1 As shown, in some embodiments, the first direction X and the second direction Y are arranged perpendicularly.

[0062] By arranging the first direction X and the second direction Y perpendicularly so that the first direction X and the second direction Y form a plane rectangular coordinate system, the accurate position of the moving direction of the first positioning member 111 or the second positioning member 121 can be further represented by the rectangular coordinate system for easy adjustment.

[0063] In some embodiments, the floating mechanism further includes a moving part driving member, which is drivingly connected to the first moving part 131 and the second moving part 132 to achieve movement and adjustment of the first moving part 131 and the second moving part 132. Specifically, the moving part driving member may have two driving members to drive the first moving part 131 and the second moving part 132, respectively, to improve the simplicity and accuracy of the drive; or the same moving part driving member may be used to drive the first moving part 131 and the second moving part 132, to reduce the volume of the floating positioning device. The moving part driving member may be a motor, or a cylinder, a hydraulic rod, etc., which is not limited in the present application.

[0064] like Figure 1 As shown, in some embodiments, the first positioning member 111 is a pin shaft, and the second positioning member 121 is a pin hole matched with the pin shaft.

[0065] The pin shaft can be cylindrical or square, and this embodiment of the application does not limit this.

[0066] The first positioning mechanism 11 and the second positioning mechanism 12 are positioned by the cooperation of the pin shaft and the pin hole. On the one hand, the pin shaft and the pin hole are easy to manufacture, and on the other hand, the positioning accuracy of the pin shaft and the pin hole is high.

[0067] In some embodiments, the end of the pin shaft is chamfered to facilitate the insertion of the pin shaft into the pin hole.

[0068] In some embodiments, the pin shaft is a tapered pin. On the one hand, the tapered pin is easy to guide into the pin hole. On the other hand, the tapered pin can still play a positioning role after the surface is worn, and the positioning accuracy is high and the reliability is strong.

[0069] like Figures 1 to 6 As shown, on the other hand, the present application provides a bending device, which includes a floating positioning device 1, a bending device 2 and a driving device 3. The bending device 2 includes a convex portion 21 and a concave portion 22 matching the convex portion 21, and the convex portion 21 and the concave portion 22 are respectively arranged on two opposite surfaces of the first positioning mechanism 11 and the second positioning mechanism 12; the driving device 3 is drivingly connected to the first positioning mechanism 11 and / or the second positioning mechanism 12.

[0070] The bending device 2 includes a convex portion 21 and a concave portion 22 matching the convex portion 21. Before bending, the convex portion 21 and the concave portion 22 are in a separated state, and the piece to be bent is placed between the convex portion 21 and the concave portion 22. During bending, the convex portion 21 is accommodated in the concave portion 22 and bends the piece to be bent between the two.

[0071] The convex portion 21 and the concave portion 22 are respectively arranged on two opposite surfaces of the first positioning mechanism 11 and the second positioning mechanism 12, that is, the convex portion 21 can be arranged on the first positioning mechanism 11, and the concave portion 22 is arranged on the surface of the second positioning mechanism 12 opposite to the first positioning mechanism 11. At this time, the convex portion 21 and the first positioning mechanism 11 can be integrally formed or separately manufactured and connected, and the present application does not impose any restrictions on this. The concave portion 22 and the second positioning mechanism 12 can also be integrally formed or separately manufactured and connected, and the present application does not impose any restrictions on this. The convex portion 21 can also be arranged on the second positioning mechanism 12, and the concave portion 22 is arranged on the surface of the first positioning mechanism 11 opposite to the second positioning mechanism 12. At this time, the convex portion 21 and the first positioning mechanism 11, and the concave portion 22 and the second positioning mechanism 12 are arranged as above, and the present application does not impose any restrictions on this.

[0072] The driving device 3 is drivingly connected to the first positioning mechanism 11 and / or the second positioning mechanism 12. That is, the driving device 3 can drive the first positioning mechanism 11 or the second positioning mechanism 12 alone to make the two move closer to or farther away from each other; the driving device 33 can also drive the first positioning mechanism 11 and the second positioning mechanism 12 at the same time to make the two move closer to or farther away from each other. At this time, the same driving device 3 can be used to drive the first positioning mechanism 11 and the second positioning mechanism 12 at the same time, or two driving devices 3 can be used to drive the first positioning mechanism 11 and the second positioning mechanism 12 respectively, and the embodiment of the present application does not limit this. The driving device 3 can be a motor, or it can be a cylinder, an electric cylinder, a screw, etc., and the present application does not limit this.

[0073] By setting the floating positioning device 1, on the one hand, the first positioning member 11 and the second positioning member 12 can float in the first direction X and the second direction Y to ensure that the two can accommodate and cooperate with each other, thereby ensuring the positioning accuracy of the positioning device; on the other hand, the floating of the floating positioning device 1 can also ensure that the convex part 21 and the concave part 22 in the bending device 2 can accommodate and cooperate with each other, thereby realizing the accurate positioning and operation of the bending equipment and improving the bending accuracy and qualified rate of the parts to be bent.

[0074] In some embodiments, the driving device 3 is a cam divider, so that the bending device has a simple structure, accurate and stable movement, and a long service life.

[0075] like Figure 6As shown, in some embodiments, the convex portion 21 includes a contact surface 211 and a bending surface 212 , the contact surface 211 is arranged corresponding to the concave portion 22 ; the bending surface 212 is arranged to intersect with the contact surface 211 .

[0076] The angle formed by the intersection of the bending surface 212 and the abutting surface 211, that is, the bending surface 212 and the abutting surface 211, can be any angle except 0° and 180°. When bending, the two bending surfaces of the part to be bent are respectively attached to the abutting surface 211 and the bending surface 212, so the angle formed by the bending surface 212 and the abutting surface 211 determines the current state of the part to be bent after bending. For example, when the part to be bent needs to be bent at 60°, it is only necessary to set the angle formed by the bending surface 212 and the abutting surface 211 to 60°.

[0077] like Figure 6 As shown, in some embodiments, the bending surface 211 and the abutting surface 212 are arranged perpendicularly.

[0078] The bending surface 211 and the abutting surface 212 are arranged perpendicularly, that is, the angle formed between the bending surface 212 and the abutting surface 211 is 90°, so that a 90° bending of the part to be bent can be achieved.

[0079] When the above-mentioned floating positioning device 1 and bending equipment have manufacturing errors, installation errors and other errors that cause the first positioning member 111 and the second positioning member 121 to be unable to accommodate and cooperate with each other and lose their positioning function, the first moving part 131 and the second moving part 132 on the floating member 13 can float the first positioning member 111 and the second positioning member 121 in the first direction X and the second direction Y to ensure that the two can accommodate and cooperate with each other, thereby ensuring the positioning accuracy of the positioning device 1. When the floating positioning device 1 is used on the bending equipment, on the one hand, the positioning accuracy can be ensured, and on the other hand, it can ensure that the convex part 21 of the bending equipment can be inserted into the concave part 22 to achieve the bending of the part to be bent placed between the concave part 22 and the convex part 21.

[0080] Specifically, Figures 1 to 6As shown, when loading, the driving device 3 drives the first positioning mechanism 11 and the second positioning mechanism 12 to be in a separated state, and places the workpiece to be bent between the convex part 21 and the concave part 22 of the bending device 2. When working, the driving device 3 drives the first positioning mechanism 11 and the second positioning mechanism 12 to approach each other, and at the same time, the floating positioning device 1 floats along the first direction X and the second direction Y to ensure that the first positioning member 111 and the second positioning member 121 are aligned, and the first positioning mechanism 11 and the second positioning mechanism 12 are driven to approach each other so that the first positioning member 111 and the second positioning member 121 are accommodated and matched to achieve precise positioning, and the first positioning mechanism 11 and the second positioning mechanism 12 are driven to approach each other so that the convex part 21 in the bending device 2 is inserted into the concave part 22, and the workpiece to be bent placed between the convex part 21 and the concave part 22 is bent. When unloading, the driving device 3 drives the first positioning mechanism 11 and the second positioning mechanism 12 to move away from each other, so that the convex part 21 is separated from the concave part 22, and the bent workpiece to be bent can be taken away.
