Description

Technical Field

[0001] The utility model relates to the technical field of robot processing, and more specifically, to a punching mechanism for processing robot accessories. Background Art

[0002] In the production of robot equipment, accessories with various structures are needed to form a complete robot. During production and processing, stamping is a common method for processing accessories of various shapes.

[0003] The common stamping mechanism has a simple structure and only has the function of stamping. In actual use, a certain amount of debris and waste will be generated during the stamping process. These wastes will remain in the lower mold. If they are not cleaned in time, they will affect the quality of the next set of stamping processes. However, after each stamping process, the workers will manually clean them, which is troublesome, affecting work efficiency, and the quality cannot be guaranteed. Moreover, after the stamping is completed, the stamped parts will fit with the mold, which is not easy to take out. The common stamping mechanism will set a push rod in the lower mold to push the parts out, but in actual processing, sometimes the parts will fit with the mold. The push rod needs a certain force to push the parts out, but too much force will push the parts away, and too little force will not push the parts out. However, different degrees of fit require different forces to push out, resulting in the push rod being unable to stably push the parts out, which is easy to affect the quality of the parts. In addition, in terms of equipment operation, the installation equipment of the upper mold needs to slide along the supporting structure. In order to avoid damage to the fit, it is necessary to apply lubricating oil frequently for maintenance, but frequent maintenance requires disassembly of the equipment, which is troublesome and inconvenient for workers to operate.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When the equipment is in use, the base 1 supports the equipment, and the support frame 2 supports the hydraulic cylinder 3. Through the operation of the hydraulic cylinder 3, the mounting plate 4 is controlled to slide along the support frame 2, and the mounting plate 4 will drive the stamping die 5 to move downward, and cooperate with the stamping seat 6 to realize the stamping process. In the use of the equipment, the content of the lubricating oil in the oil storage tank 17 is observed, and the lubricating oil is poured into the oil storage tank 17 to ensure sufficient lubrication. When the equipment is working, the mounting plate 4 moves along the support frame 2, and at the same time, it will drive the sponge ring 18 below to move. After the lower end of the sponge ring 18 enters the oil storage tank 17, it will absorb part of the lubricating oil, and the lubricating oil will diffuse in the sponge ring 18. In the process of driving the sponge ring to move, lubricating oil is applied to the rod structure of the support frame 2, and the matching structure of the mounting plate 4 and the support is maintained to ensure the smooth operation of the equipment. In addition, when the mounting plate 4 drives the stamping die 5 to descend, it will drive the positioning rod 27 to move together. Through the cooperation of the positioning rod 27 and the positioning groove 28, the positioning rod 27 is inserted into the positioning groove 28 to position the processing of the stamping die 5. When the positioning rod 27 is inserted into the positioning groove 28, it will contact with the buffer pad 29 to offset the impact caused by the collision. At the same time, the mounting plate 4 is supported by the positioning rod 27 to avoid the downward pressure of the stamping die 5 causing damage to the stamping die 5 or the stamping seat 6.

[0050] After the stamping process is completed, the mounting plate 4 drives the stamping die 5 to move upward and leave the stamping seat 6 under the power of the hydraulic cylinder 3, and removes the processed robot accessory area. When taking materials, the control motor 23 provides power, and the control motor 23 drives the matching block 15 to rotate through the cooperation of the transmission gear 24 and the transmission gear ring 25, so as to ensure the stability of the rotation of the matching block 15, so that the matching block 15 is matched with the matching column 14 through the inclined table 16, and the inclined table 16 contacts the matching column 14, and under the rotation of the matching block 15, the contact surface between the inclined table 16 and the matching column 14 is gradually increased, and the thrust of the reset spring 26 is used to press the matching disk 13 downward, so that the matching column 14 is close to the inclined table 16, so as to ensure the stable matching and push the matching column 14 to move upward. Thereby, the matching disk 13 moves upward, the driving push rod 12 moves upward, and the accessories on the stamping seat 6 are pushed out. Before the new accessories to be stamped are loaded, the driving motor 8 is controlled to work. Under the support of the mounting frame 7, the driving motor 8 drives the driving screw 9 to rotate, and the transmission is carried out through the cooperation of the transmission wheel 21 and the transmission belt 22, so that the two driving screws 9 rotate synchronously, and the rotating driving screw 9 cooperates with the cleaning frame 10 to drive the cleaning frame 10 to move, so that the cleaning frame 10 drives the cleaning brush 11 to move along the stamping seat 6, and the cleaning brush 11 is used to clean the waste debris in the stamping seat 6, and the storage groove 19 is used for the installation of the storage box 20. When cleaning the waste debris, the waste falls into the storage box 20, and the storage box 20 can be removed from the storage groove 19 for easy disposal.
