Description

[0002] Brake disc processing includes the following steps: casting blank, rough machining, heat treatment, finish machining, drilling and milling, surface treatment, etc. In the existing technology, during finish machining, drilling and milling operations, a robot arm is used to transfer the brake disc to each processing station. During this process, there is an operation that requires flipping the brake disc. The existing flipping operation involves the robot arm placing the retrieved brake disc at a temporary placement point, then the robot arm's suction cup part flips to the bottom of the brake disc to suction it. After that, the robot arm continues to operate to transfer the brake disc to the next processing station. In this way, the brake disc flipping operation between two stations is completed.

[0003] During the above operation, the robotic arm needs to perform multiple actions at the temporary placement point, such as: aligning with the placement point, lowering the brake disc, flipping the suction cup part, and adsorbing the brake disc again. During long working periods, this action will take up a lot of working time, and the efficiency of the brake disc flipping action needs to be further improved. Based on this, a new type of brake disc tooling fixture is provided. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 In this embodiment of the utility model, a novel brake disc tooling fixture includes a bracket assembly 1 and a clamping assembly 2. The clamping assembly 2 is used to adsorb and fix the brake disc. The bracket assembly 1 includes a horizontal arm 101 and a linear guide groove 102.

[0038] Multiple vacuum suction cups 202 are provided, and the multiple vacuum suction cups 202 are installed in a ring on the end face of the fixture frame 201. The connecting shaft 203 is fixed to the other end face of the fixture frame 201, and the connecting shaft 203 extends to the through linear guide groove 102.

[0041] The connecting shaft 203 passes through one side of the horizontal arm 101 via the linear guide groove 102 and is connected and fixed to the driven gear 204. The fixed gear plate 206 is symmetrically fixed at both ends of one side of the horizontal arm 101, and the fixed gear plate 206 is located at the bottom of the connecting shaft 203 and meshes with the connecting shaft 203.

[0042] Two L-shaped toothed arms 205 are provided. The two L-shaped toothed arms 205 are rotatably connected to the outside of the two connecting shafts 203 respectively. The transmission gear 207 is rotatably connected to one side of the middle of the linear guide groove 102 through the rotating shaft. The two L-shaped toothed arms 205 are circumferentially distributed with the transmission gear 207 as the center. The two L-shaped toothed arms 205 and the transmission gear 207 mesh synchronously.

[0043] The connecting block 208 is fixed to the top of the L-shaped toothed arm 205 distributed above the transmission gear 207, and the output end of the pneumatic push rod 209 is fixedly connected to the connecting block 208.

[0044] When the pneumatic push rod 209 drives an L-shaped toothed arm 205 to move horizontally, the transmission gear 207 drives another L-shaped toothed arm 205, and the driven gear 204 cooperates with the fixed toothed plate 206 to realize that the two sets of adsorption units first rotate 180 degrees and then move horizontally closer, thereby realizing the flipping operation of the brake disc 4.

[0045] A concave connecting seat 103 is fixed on the outer side of the cross arm 101. The driven gear 204, L-shaped toothed arm 205, fixed toothed plate 206, and transmission gear 207 are distributed inside the concave connecting seat 103.

The pneumatic push rod 209 is fixed on the top of the concave connecting seat 103.

[0046] A connecting arm 105 is fixed on the side of the concave connecting seat 103 away from the horizontal arm 101. The connecting arm 105 is used to connect to the front output shaft of the robotic arm.

[0047] The limiting guide unit includes a limiting guide block 210 and a limiting guide rail 211;

[0048] The limiting guide block 210 is fixed to the outside of the connecting shaft 203, and the limiting guide block 210 and the driven gear 204 are symmetrically attached to both sides of the outer wall of the cross arm 101.

[0049] The limiting guide rail 211 and the connecting shaft 203 are distributed on the same side of the cross arm 101, and the limiting guide rail 211 is fixed vertically on the outside of the cross arm 101 with the linear guide groove 102 as the center.

[0050] The limiting guide rail 211 and the fixed toothed plate 206 are staggered in the horizontal direction.

[0051] In this embodiment: This tooling fixture is used to realize the loading and unloading operations of the brake disc 4 at two workstations. In normal state, the two sets of adsorption units are symmetrically distributed far apart from each other. At this time, the brake disc 4 to be processed can be adsorbed by a set of vacuum suction cups 202. Then, the robotic arm moves to move the brake disc 4 to the processing workstation, so that the other set of vacuum suction cups 202 approaches the already processed brake disc 4 and adsorbs and fixes it. Then, the robotic arm moves to move the processed brake disc 4 away from the processing workstation and rotates the entire bracket assembly 1 180 degrees, so that the brake disc 4 to be processed faces the processing workstation. Then, the robotic arm moves to place the brake disc 4 to be processed into the processing workstation, thus completing the loading and unloading operation of one processing workstation.

[0052] Afterwards, the robotic arm can transfer the removed brake disc 4 to the next processing station. If it is necessary to flip the brake disc 4 during this process, the operation method is as follows:

[0053] When the pneumatic push rod 209 is activated, it pushes one L-shaped toothed arm 205 closer to the other L-shaped toothed arm 205. Through the transmission of the transmission gear 207, the two L-shaped toothed arms 205 can move and approach synchronously. The two L-shaped toothed arms 205 can drive the two sets of adsorption units to approach. At the same time, the driven gear 204 rotates 180 degrees under the limiting action of the fixed tooth plate 206, that is, the two sets of adsorption units are flipped 180 degrees. At this time, the two sets of vacuum suction cups 202 approach each other. At the same time, the brake disc 4 is driven to flip 180 degrees and is located in the middle area of ​​the two sets of vacuum suction cups 202.

[0054] During the above process, when the driven gear 204 separates from the fixed gear plate 20, the limiting guide block 210 rotates 180 degrees synchronously with the connecting shaft 203 and remains horizontal. At this time, the limiting guide block 210 is located at the port of the two limiting guide rails 211. After that, the pneumatic push rod 209 continues to run, and its limiting guide block 210 will move along the middle track of the two limiting guide rails 211, thereby making the two sets of adsorption units maintain stable horizontal movement. Finally, the brake disc 4 is attached to another set of vacuum suction cups 202. At this time, the two sets of vacuum suction cups 202 are switched so that the brake disc 4 is adsorbed and fixed by the other set of vacuum suction cups 202, while the previous vacuum suction cups 202 release the adsorption of the brake disc 4.

[0055] Afterwards, the pneumatic push rod 209 resets, causing the two sets of adsorption units to return to their initial positions. At this time, the brake disc 4 completes the flipping operation. The above operations can be performed during the process of the robotic arm driving the brake disc 4 to the next workstation, thus realizing the efficient transfer operation of the brake disc 4 between two workstations.

[0056] Please refer to this carefully. Figures 1-4The height of the horizontally distributed limiting guide block 210 matches the height of the distance between the two limiting guide rails 211, and the two ends of the lower limiting guide rail 211 extend beyond the two ends of the upper limiting guide rail 211.

[0057] In this embodiment: the limiting guide rail 211 can limit the movement of the limiting guide block 210 to ensure the stability of the adsorption unit when it moves horizontally and avoid the adsorption unit from deflecting, thereby achieving stable docking between the brake disc 4 and another set of vacuum suction cups 202.

[0058] Please refer to this carefully. Figures 1-4 Two supporting arc-shaped seats 3 are symmetrically fixed at the upper and lower ends of the middle part of the cross arm 101. The inner diameter of the two supporting arc-shaped seats 3 matches the outer diameter of the brake disc 4.

[0059] In this embodiment: when the brake disc 4 is in contact with another set of vacuum suction cups 202, the brake disc 4 is located in the middle of the two supporting arc-shaped seats 3. The two supporting arc-shaped seats 3 can provide limit and support for the brake disc 4, so that the position of the brake disc 4 can be kept stable when the two sets of vacuum suction cups 202 switch adsorption.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
