Technical Field
[0001] This utility model relates to the field of mechanical engineering, and more specifically, to a gantry machining auxiliary bracket that facilitates workpiece flipping. Background Technology
[0002] The gantry machining bracket is a core auxiliary device of the gantry machining center. It is mainly used for workpiece support and positioning and is widely used in high-end manufacturing fields such as aerospace, automobile manufacturing, and heavy machinery. During the machining process, the bracket is used to flip and adjust the position of the workpiece so that the machining equipment can perform precision machining on various parts of the workpiece.
[0003] A search revealed that Chinese Patent Publication No. CN221817944U discloses "a lead screw support assembly for a gantry machining center, including a base plate, with guide rails fixedly connected to the front and rear sides of the top of the base plate, two connecting frames movably connected between the tops of the two guide rails, and an adjusting shell fixedly connected between the tops of the two connecting frames. An adjusting component is fixedly connected to the bottom of the inner cavity of the adjusting shell, the adjusting component including a dual-axis motor, a limiting shell, and a movable shell, an auxiliary mechanism provided on the top of the adjusting shell, and limiting holes on both sides of the bottom of the adjusting shell. The bottom of the dual-axis motor is fixedly connected to the bottom of the inner cavity of the adjusting shell. This utility model provides a lead screw support assembly for a gantry machining center that solves the problem that existing lead screws lack any support structure in the middle, thus the lead screw is easily deformed by heavy objects during long-term transport, causing damage." However, the following defects still exist:
[0004] When using this device, different surfaces of the workpiece often need to be machined during the workpiece processing. Since the workpiece cannot be rotated, the installation position of the workpiece needs to be readjusted or the parts re-clamped when machining the sides or back of the workpiece. This not only increases auxiliary time for workpiece processing but also reduces processing efficiency. Therefore, a gantry machining auxiliary bracket that facilitates workpiece flipping is proposed. Utility Model Content
[0005] The purpose of this utility model is to address the current problem that during the workpiece processing process, it is often necessary to process different surfaces of the workpiece, but the workpiece cannot be rotated. As a result, when processing the side or back of the workpiece, it is necessary to readjust the installation position of the workpiece or re-clamp the parts, which not only increases the auxiliary time of workpiece processing, but also reduces the workpiece processing efficiency.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] The present invention is as follows: a gantry machining auxiliary bracket for facilitating workpiece flipping, comprising a frame, wherein a flipping component for flipping the workpiece is provided inside the frame, and an error-proofing component for preventing workpiece flipping errors is provided on one side of the frame.
[0008] The flipping assembly includes a servo motor bolted to one side of the frame. A lead screw is coaxially mounted on the output end of the servo motor. A bracket is threaded onto the outer wall of the lead screw. A crossbar passes through the interior of the bracket. A first electric push rod is mounted on the inner top wall of the bracket. A fixed frame is mounted on the output end of the first electric push rod. A second electric push rod is mounted on the inner top wall of the fixed frame. An L-shaped frame is mounted on the output end of the second electric push rod. The L-shaped frame is rotatably connected to the inner wall of the fixed frame. An electric clamp is fixedly connected to the side of the L-shaped frame away from the second electric push rod.
[0009] As a preferred technical solution of this utility model, the error prevention component includes an inclined plate fixedly connected to one side of the support, a high-definition camera is provided on one side of the inclined plate, a controller is provided on the top of the frame, and the high-definition camera, the second electric push rod and the electric clamp are all electrically connected to the controller.
[0010] As a preferred technical solution of this utility model, two stabilizing plates are fixedly connected to opposite sides of the bracket, and both stabilizing plates are slidably connected to the top of the frame.
[0011] As a preferred technical solution of this utility model, the outer wall of the crossbar is provided with two limiting rings, and each of the two limiting rings is provided with a plastic pad on the side near the bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. By setting up a flipping component, the workpiece can be flipped quickly. The servo motor drives the lead screw to rotate, which drives the bracket to move smoothly back and forth in the horizontal direction. The first electric push rod adjusts the height of the fixed frame to ensure that the workpiece is clamped in the optimal position. The electric clamp applies a stable clamping force to the workpiece. The second electric push rod cooperates with the L-shaped frame to flip the workpiece smoothly, which significantly improves the workpiece flipping efficiency.
[0017] 2. By setting up error-proof components, the effect of timely adjustment of the flipped workpiece is achieved.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] like Figure 1 As shown, this embodiment proposes a gantry machining auxiliary bracket that facilitates workpiece flipping, including a frame 1, a flipping component 2 for flipping the workpiece is provided inside the frame 1, and an error-proofing component 3 for preventing workpiece flipping errors is provided on one side of the frame 1.
[0029] like Figure 2 and Figure 3As shown, the flipping assembly 2 includes a servo motor 201 bolted to one side of the frame 1. A lead screw 202 is coaxially mounted on the output end of the servo motor 201. A bracket 203 is threaded onto the outer wall of the lead screw 202. A crossbar 204 passes through the interior of the bracket 203. By starting the servo motor 201, the lead screw 202 is rotated, thereby driving the bracket 203 to reciprocate. A first electric push rod 205 is mounted on the inner top wall of the bracket 203. A fixing bracket 206 is mounted on the output end of the first electric push rod 205. The first electric push rod 205 is activated, which drives the fixed frame 206 to move up and down. The inner top wall of the fixed frame 206 is provided with a second electric push rod 207. The output end of the second electric push rod 207 is provided with an L-shaped frame 208. The L-shaped frame 208 is rotatably connected to the inner wall of the fixed frame 206. An electric clamp 209 is fixedly connected to the side of the L-shaped frame 208 away from the second electric push rod 207. By activating the second electric push rod 207, the electric clamp 209 on the L-shaped frame 208 is driven to adjust the angle. The servo motor 201 is started, which drives the lead screw 202 to rotate. The rotation of the lead screw 202 causes the bracket 203 to reciprocate linearly, which in turn drives the fixed frame 206 on the first electric push rod 205 to move synchronously. The crossbar 204 provides stable support for the bracket 203, ensuring that the bracket 203 is stable and without deviation during the reciprocating motion. The first electric push rod 205 on the bracket 203 pushes the fixed frame 206 and the electric clamp 209 to achieve height adjustment to meet the clamping requirements of workpieces of different sizes. The electric clamp 209 is started to stably clamp the workpiece. Subsequently, according to the extension and retraction of the second electric push rod 207, the angle of the L-shaped frame 208 and the electric clamp 209 are adjusted to realize multi-angle flipping operation of the workpiece, which not only reduces manual operation, but also improves the flipping efficiency of the workpiece.
[0030] like Figure 3 As shown, the error-proofing component 3 includes an inclined plate 301 fixedly connected to one side of the support 203. A high-definition camera 302 is installed on one side of the inclined plate 301, and a controller 303 is installed on the top of the frame 1. The high-definition camera 302 detects the workpiece's flipping status information in real time and transmits it to the controller 303. The high-definition camera 302, the second electric push rod 207, and the electric clamp 209 are all electrically connected to the controller 303. The high-definition camera 302 on the inclined plate 301 moves with the support 203. The high-definition camera 302 detects the workpiece's status information in real time during the flipping process and transmits signals to the controller 303. When an error in workpiece flipping is detected, the high-definition camera 302 transmits a signal to the controller 303. The controller 303 can control the second electric push rod 207 and the electric clamp 209 to perform corresponding adjustment operations, promptly detect and correct flipping errors, avoid poor processing or damage to the electric clamp 209 due to flipping errors, and significantly improve workpiece flipping efficiency and production safety.
[0031] like Figure 5 As shown, two stabilizing plates 4 are fixedly connected to opposite sides of the bracket 203, and both stabilizing plates 4 are slidably connected to the top of the frame 1. The stabilizing plates 4 prevent the bracket 203 from shaking or tilting during movement, ensuring the positional accuracy of the workpiece during flipping and moving, and effectively improving the stability of the bracket 203.
[0032] like Figure 4 As shown, the outer wall of the crossbar 204 is provided with two limiting rings 5, and each of the two limiting rings 5 has a plastic pad 6 on the side near the bracket 203. When the bracket 203 moves on the crossbar 204, the limiting rings 5 restrict the range of movement of the bracket 203, ensuring that the bracket 203 always operates within the preset range and avoids collisions with other components. When the bracket 203 contacts the limiting ring 5, the plastic pad 6 acts as a buffer, reducing damage to the bracket 203 and the limiting ring 5 from the collision and extending the service life of the equipment.
[0033] like Figure 5 As shown, a warning light 7 is installed on one side of the frame 1, and the warning light 7 is electrically connected to the controller 303. When the high-definition camera 302 detects an abnormal workpiece flipping posture or positional deviation in real time, it transmits a signal to the controller 303. The controller 303 then controls the warning light 7 to illuminate, issuing a warning signal. This promptly alerts the operator that an error has occurred in the workpiece flipping, allowing the operator to take appropriate measures to handle the situation and prevent the problem from escalating further.
[0034] like Figure 5 As shown, the contact area between the electric clamp 209 and the workpiece is provided with an anti-slip pad 8, and multiple anti-slip grooves 9 are formed on one side of the anti-slip pad 8. When the electric clamp 209 clamps the workpiece, the anti-slip grooves 9 on the surface of the anti-slip pad 8 significantly increase the friction between the workpiece and the clamp, thereby effectively improving the clamping stability and preventing the workpiece from shifting or slipping during the flipping process.
[0035] like Figure 5 As shown, a protective cover 10 is bolted to one side of the frame 1, and the outer wall of the protective cover 10 has multiple heat dissipation holes 11. The protective cover 10 provides stable protection for the servo motor 201, preventing damage to the servo motor 201 caused by external dust and other phenomena. At the same time, the heat generated by the servo motor 201 during operation is dissipated to the outside through the heat dissipation holes 11, ensuring that the servo motor 201 is always within the optimal operating temperature range.
[0036] Specifically, when using this gantry machining auxiliary support that facilitates workpiece flipping: The servo motor 201 is started, driving the lead screw 202 to rotate. The rotation of the lead screw 202 causes the support 203 to reciprocate linearly, which in turn drives the fixed frame 206 on the first electric push rod 205 to move synchronously. The crossbar 204 provides stable support for the support 203, ensuring that the support 203 moves smoothly and without deviation during reciprocating motion. The first electric push rod 205 on the support 203 pushes the fixed frame 206 and the electric clamp 209 to achieve height adjustment to accommodate the clamping requirements of workpieces of different sizes. The electric clamp 209 is activated to stably clamp the workpiece. Subsequently, based on the extension and retraction of the second electric push rod 207, the angles of the L-shaped frame 208 and the electric clamp 209 are adjusted to achieve multi-angle flipping operations of the workpiece (e.g., ...). Figure 2 and Figure 3 (As shown); The high-definition camera 302 on the inclined plate 301 moves with the support 203. The high-definition camera 302 detects the status information of the workpiece in real time during the flipping process and transmits the signal to the controller 303. When an error in workpiece flipping is detected, the high-definition camera 302 transmits the signal to the controller 303. The controller 303 can control the second electric push rod 207 and the electric clamp 209 to perform corresponding adjustment operations, so as to detect and correct the flipping error in time and avoid poor processing or damage to the electric clamp 209 due to the flipping error (e.g., Figure 3 (As shown); this not only reduces manual operation but also improves the workpiece flipping efficiency.
[0037] All technical features in this embodiment can be freely combined according to actual needs.
[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
