[0047] For better explanation of this, for the sake of understanding, the following will combine the drawings and describe this in detail through specific embodiments. Among them, the orientation terms such as "up" and "down" mentioned in this article are based on Figure 1 the orientation of Figure 1 .

[0048] Refer to Figures 1-6 , the workpiece turnover mechanism proposed in this embodiment includes a first bracket 1, a clamping tooling 2 and a turnover driver 3.

[0049] A chute 111 is opened on the first bracket 1.

[0050] The clamping tooling 2 can detachably clamp the two end faces of at least one workpiece 5 stacked, and a circular slider 21 is arranged on the clamping tooling 2. The circular slider 21 is slidably arranged on the chute 111 and can rotate around its own axis in the chute 111.

[0051] The turnover driver 3 is drivingly connected to the first bracket 1 and is used to drive the first bracket 1 to rotate around the first end of the first bracket 1 and switch between the first state and the second state.

[0052] When the first bracket 1 is in the first state, the chute 111 is vertically oriented, and the clamping tooling 2 can clamp the two end faces of at least one workpiece 5 with an axial vertical orientation.

[0053] When the second support 4 is in the second state, the chute 111 is horizontally oriented, and the clamping tooling 2 can drive at least one workpiece 5 with a horizontal axis to rotate around the axis of the circular slider 21 so that the end faces of both ends of at least one workpiece 5 are reversed with each other.

[0054] Specifically, the usage method of the workpiece turning mechanism is as follows:

[0055] S1: First, drive the first support 1 to rotate to the first state around the first end through the turning driver 3. At this time, the chute 111 is vertically oriented. Hoist at least one workpiece 5 with one machined end face onto the clamping tooling 2 to form a stack of workpieces 5 stacked one on top of the other, and make the clamping tooling 2 clamp the end faces of both ends of at least one workpiece 5 with a vertical axis.

[0056] S2: Subsequently, the turning driver 3 drives the first support 1 to rotate to the second state. At this time, the chute 111 is horizontally oriented, the axis of at least one workpiece 5 clamped by the clamping tooling 2 is horizontal, and the clamping tooling 2 can drive at least one workpiece 5 to rotate 180° around the axis of the circular slider 21 within the chute 111 so that the end faces of both ends of at least one workpiece 5 are reversed with each other.

[0057] S3: Then, the turning driver 3 drives the first support 1 to rotate to the first state. At this time, the chute 111 is vertically oriented, the axis of at least one workpiece 5 clamped by the clamping tooling 2 is vertical and the end faces at both ends have completed turning and surface conversion. Then unlock at least one workpiece 5 and the clamping tooling 2, and hoist at least one workpiece 5 one by one onto the processing platform to process the other end face of the workpiece 5.

[0058] Thus, this workpiece turning mechanism can mechanically turn at least one workpiece 5 by 180° in place simultaneously to realize the surface conversion processing of both end faces. At the same time, the structure of this workpiece turning mechanism is simple, low-cost and occupies a small area.

[0059] It should be noted that the workpiece 5 is a plate-shaped workpiece, the peripheral wall and the upper and lower end faces of the workpiece 5 are all planes, and multiple workpieces 5 can be stacked one on top of the other. When at least one workpiece 5 is stacked to form a stack of workpieces 5, the clamping tooling 2 can clamp the end faces of the two workpieces 5 located at both ends in the stack of workpieces 5. The workpiece 5 can be a plate-shaped component of a bridge bearing or a plate-shaped component in other fields.

[0060] Furthermore, the clamping tooling 2 includes a first clamping body 22 and a second clamping body 23 which are oppositely arranged and the distance between them is adjustable, and the first clamping body 22 and the second clamping body 23 are detachably connected. The first clamping body 22 and the second clamping body 23 can clamp the end faces of both ends of at least one workpiece 5 stacked and arranged. A circular slider 21 is arranged on the first clamping body 22.

[0061] In step S1, first, the first bracket 1 is driven by the flipping driver 3 to rotate around the first end to the first state. At this time, the chute 111 is vertically oriented. At least one workpiece 5 with one machined end face is lifted and transported onto the first clamping body 22 to form a stack of workpieces 5 stacked one on top of the other. Subsequently, the second clamping body 23 is installed onto the first clamping body 22 so that the vertically opposed first clamping body 22 and the second clamping body 23 can clamp the two end faces of at least one workpiece 5 arranged in a stack.

[0062] In step S2, when the chute 111 is horizontally oriented, the first clamping body 22 and the second clamping body 23 are horizontally opposed and the axis of at least one workpiece 5 clamped by them is horizontal.

[0063] In step S3, the axis of at least one workpiece 5 clamped by the clamping tooling 2 is vertical and the two end faces are completed with flipping and surface conversion. The second clamping body 23 is removed from the first clamping body 22 so that at least one workpiece 5 and the clamping tooling 2 are unlocked.

[0064] Furthermore, both the first clamping body 22 and the second clamping body 23 are L-shaped and are arranged oppositely.

[0065] An insertion slot 221 is formed on the first clamping body 22. The second clamping body 23 can be inserted into the insertion slot 221 and move along the length direction of the insertion slot 221 to adjust the distance between the first clamping body 22 and the second clamping body 23.

[0066] A pressing member 24 capable of moving along the width direction of the insertion slot 221 is further arranged on the first clamping body 22. The pressing member 24 can press against or disengage from the second clamping body 23 in the insertion slot 221.

[0067] It should be noted that the opposing surfaces of the first clamping body 22 and the second clamping body 23 can respectively clamp the end faces of the two workpieces 5 located at both ends in the stacked workpieces 5, and the parallel surfaces of the first clamping body 22 and the second clamping body 23 can abut against the peripheral wall planes of the stacked workpieces 5 to stably clamp the stacked workpieces 5.

[0068] During use, when the second clamping body 23 needs to be installed onto the first clamping body 22: after inserting the second clamping body 23 into the insertion slot 221 of the first clamping body 22, adjust the distance between the first clamping body 22 and the second clamping body 23 to be applicable to clamping at least one workpiece 5 with different thicknesses. After the distance is adjusted, move the pressing member 24 along the width direction of the insertion slot 221 so that the pressing member 24 presses against the second clamping body 23 in the insertion slot 221.

[0069] When the second clamping body 23 needs to be unlocked from the first clamping body 22: move the pressing member 24 along the width direction of the insertion slot 221 so that the pressing member 24 disengages from the second clamping body 23 in the insertion slot 221. Subsequently, pull out the second clamping body 23 from the insertion slot 221.

[0070] Specifically, a threaded hole is formed on one side of the first clamping body 22, and a pressing member 24 is threadedly connected in the threaded hole.

[0071] During use, when the pressing member 24 is rotated, the pressing member 24 can move along the width direction of the insertion groove 221.

[0072] More specifically, the pressing member 24 is a threaded rod.

[0073] Furthermore, the first bracket 1 includes a first plate 11 and a second plate 12 that are perpendicularly arranged to each other.

[0074] The intersection of the first plate 11 and the second plate 12 forms the first end of the first bracket 1.

[0075] Chute 111 is arranged in parallel on the first plate 11, and the clamping tooling 2 inserted into the chute 111 can abut against the second plate 12.

[0076] When the first bracket 1 is in the first state, the first plate 11 and the chute 111 are both vertically oriented.

[0077] When the first bracket 1 is in the second state, the first plate 11 and the chute 111 are both horizontally oriented.

[0078] Specifically, in step S1, after the clamping tooling 2 clamps the two end faces of at least one workpiece 5 with a vertical axis, the clamping tooling 2 is pushed along the chute 111 until it abuts against the second plate 12. The second plate 12 supports the clamping tooling 2 to prevent the clamping tooling 2 from shaking during the process of the first bracket 1 driving the clamping tooling 2 to rotate.

[0079] In step S2, when the chute is horizontally oriented and the axis of at least one workpiece 5 clamped by the clamping tooling is horizontal, the clamping tooling 2 is moved along the chute 111 to move away from the second plate 12. Then, the clamping tooling can drive at least one workpiece 5 to rotate 180° around the axis of the circular slider in the chute so that the two end faces of at least one workpiece 5 are reversed with each other. Subsequently, the clamping tooling 2 is pushed along the chute 111 until it abuts against the second plate 12.

[0080] Furthermore, the first end of the chute 111 extends to the second plate 12, and the second end of the chute 111 extends to form a socket 1111.

[0081] The circular slider 21 can be inserted into or slid out of the chute 111 through the socket 1111 for easy installation.

[0082] Furthermore, the workpiece flipping mechanism further includes a second bracket 4 for supporting the whole mechanism.

[0083] The first end of the first bracket 1 is rotatably connected to the top of the second bracket 4.

[0084] The main body of the flipping driver 3 is rotatably connected to the second bracket 4, and the driving end of the flipping driver 3 is rotatably connected to the first bracket 1. Moreover, the driving end of the flipping driver 3 can extend and contract to drive the first bracket 1 to rotate around the first end of the first bracket 1.

[0085] Preferably, the flipping driver 3 is a cylinder.

[0086] Furthermore, the longitudinal cross-sections on both sides of the width of the chute 111 are opposite inverted L-shapes.

[0087] An annular insertion block 211 protrudes from the outer peripheral wall of the lower part of the circular slider 21.

[0088] The annular insertion block 211 can be inserted into the chute 111 through the insertion opening 1111 to facilitate loading and unloading, and prevent the circular slider 21 from detaching from the chute 111 during the rotation of the first bracket 1.
