Description

Technical Field

[0001] This utility model relates to the field of precision manufacturing technology, and in particular to a 0-proportion track hole enlargement, shaping and riveting workstation. Background Technology

[0002] 0-scale tracks are product parts used in train model sand tables. They are an indispensable part of train model sand tables. The track forming process is steel plate roll forming. After the track roll forming process, the track cross-section will have deformation, burrs and other phenomena. Therefore, it is necessary to do hole enlargement and shaping work at the end, as well as riveting connecting shafts and further riveting processes for the track end.

[0003] The existing 0-scale track manufacturing process mainly consists of three steps: hole enlargement, shaping, and riveting of the splicing shaft. It requires three machines and three operators to complete the production of the 0-scale track. Since the above process adopts a semi-manual and semi-mechanical manufacturing mode, it has the following disadvantages. For example, in the hole enlargement and shaping processes, manual hole alignment may lead to misalignment of the track angle, resulting in an increased hole diameter. In the riveting process, workers hold the track plug and splicing shaft by hand and then use a press to rivet it, which has the problem of uncontrollable force and angle. At the same time, the semi-manual and semi-mechanical manufacturing mode not only has safety hazards, but also has higher production costs.

[0004] In view of this, there is an urgent need for a 0-scale track hole enlargement, shaping and riveting workstation to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see the appendix Figure 1-6 A 0-scale track hole enlargement, shaping, and riveting workstation, comprising:

[0026] The system comprises a base 1, a six-axis robot 2, a track roller press 3, a riveting fixture 4, a hole-expanding and shaping fixture 5, and an electrical control cabinet 6. The track roller press 3 is installed at the edge of the base 1. The riveting fixture 4 and the hole-expanding and shaping fixture 5 are installed at the end of the base 1 away from the track roller press 3, and are located on the same vertical axis. The six-axis robot 2 is located between the track roller press 3 and the riveting fixture 4, and is installed on the base 1. The electrical control cabinet 6 is installed at a corner of the base 1, and is electrically connected to the six-axis robot 2, the track roller press 3, the riveting fixture 4, and the hole-expanding and shaping fixture 5.

[0027] In this invention, a six-axis robot 2, a track roller press 3, a riveting fixture 4, and a hole-expanding and shaping fixture 5 are highly integrated on a base 1. The auxiliary operator controls the system through an electrical control cabinet 6. After the parts to be processed undergo basic testing by the track roller press 3, the six-axis robot 2 picks up the track that has passed the initial testing and moves it to the hole-expanding and shaping fixture 5 for hole expansion. After hole expansion, the six-axis robot 2 continues to pick up the parts to be processed and moves them to the riveting fixture 4. The entire processing process is different from the traditional semi-manual and semi-mechanical manufacturing method. The number of operators is reduced from four general workers to one auxiliary operator, saving at least 50% in terms of labor costs. At the same time, in the semi-manual and semi-mechanical manufacturing method, the processing time for a single part is about 18-20 seconds, while the highly integrated workstation only takes 9-11 seconds to process a single part, which greatly improves manufacturing efficiency and indirectly reduces manufacturing costs.

[0028] It should be noted that the electrical control cabinet 6 is equipped with a PLC control system. This means that the auxiliary operator does not need to control the six-axis robot 2, the riveting fixture 4 and the hole reaming fixture 5 in sequence. They only need to start the processing button on the electrical control cabinet 6 to achieve the purpose of automatically completing multiple processes.

[0029] Specifically, the base 1 is provided with a protective frame 10 that is detachably connected to it. The protective frame 10 is U-shaped. The track roller press 3 is located on one side of the notch of the protective frame 10, and the protective frame 10 is provided with a discharge port 100 on the side wall away from the track roller press 3.

[0030] Considering the potential for mechanical injury to operators during machining, a protective frame 10 is installed around the base 1. This provides effective protection for operators without affecting machining, thus avoiding potential safety hazards during processing.

[0031] Specifically, the six-axis robot 2 includes a robotic arm 20, a pneumatic finger cylinder 21, a contour gripper 22, and a vision camera 23. The robotic arm 20 is mounted on the base 1. One end of the pneumatic finger cylinder 21 is connected to the robotic arm 20, and the other end is connected to the contour gripper 22. The vision camera 23 is fixedly connected to the side wall of the contour gripper 22.

[0032] The six-axis robot 2 achieves positional movement in the general direction through the robotic arm 20, and controls the gripping of the contour gripper 22 through the pneumatic finger cylinder 21. Considering that it is inconvenient for the operator located at the electrical control cabinet 6 to observe the gripping situation of the contour gripper 22, a vision camera 23 is set on the side wall of the contour gripper 22 to transmit real-time images. It should be noted that, under the premise of achieving real-time observation, the position of the vision camera 23 can be installed according to actual needs.

[0033] Specifically, the riveting fixture 4 includes a first irregularly shaped mounting frame 40, a riveting cylinder 41, a push-in cylinder 42, and a clip-type feed box 43. The lower end of the first irregularly shaped mounting frame 40 is fixedly connected to the base 1, and the clip-type feed box 43 is fixedly connected to the upper end of the first irregularly shaped mounting frame 40. The riveting cylinder 41 is vertically mounted at the lower end of the first irregularly shaped mounting frame 40. The push-in cylinder 42 is located between the riveting cylinder 41 and the clip-type feed box 43, and is horizontally mounted on the side of the first irregularly shaped mounting frame 40. The piston rods of the riveting cylinder 41 and the push-in cylinder 42 are located in the same working space. The riveting cylinder 41 and the push-in cylinder 42 are electrically connected to the electrical control cabinet 6.

[0034] After initial inspection, the track moves to the working area of ​​the riveting fixture 4 along with the six-axis robot 2. The pneumatic push-in cylinder 42 pushes the splicing shaft at the lower end of the magazine-type feed box 43, causing the splicing shaft to move toward the track to be riveted and ensuring that the splicing shaft is pushed into the inner hole of the track. Then, the riveting cylinder 41 is activated, and the piston rod of the riveting cylinder 41 moves vertically to contact the track to be riveted. Under the action of the riveting cylinder 41, the final riveting of the track to be riveted is completed.

[0035] Specifically, the hole-expanding and shaping fixture 5 includes a second irregular-shaped mounting bracket 50, a servo motor 51, a servo slide 52, and a shaping cylinder 53. The lower end of the second irregular-shaped mounting bracket 50 is fixedly connected to the base 1. The servo slide 52 is slidably connected to the second irregular-shaped mounting bracket 50. The servo motor 51 is horizontally fixedly connected to one end of the servo slide 52 near the second irregular-shaped mounting bracket 50, and a matching hole-expanding needle 510 is installed on the servo motor 51. The shaping cylinder 53 is vertically installed at the lower end of the second irregular-shaped mounting bracket 50. The servo motor 51 and the shaping cylinder 53 are electrically connected to the electrical control cabinet 6.

[0036] The second irregular mounting bracket 50 is fixed on the base 1, and the servo slide 52 is slidably connected to the second irregular mounting bracket 50. When performing hole enlargement and shaping, after the six-axis robot 2 uses the contour gripper 22 to pick up the track component and place it in a position that matches the hole enlargement and shaping fixture 5, the pneumatic shaping cylinder 53 is first activated to make the piston rod of the shaping cylinder 53 move vertically and move with the track. The track is shaped by the pressure of the piston rod. Then, the pneumatic servo motor 51 drives the hole enlargement needle 510 to move along the axial direction of the servo motor 51 and gradually probe into the track to complete the hole enlargement operation of the track.

[0037] Specifically, the first irregular mounting bracket 40 and the second irregular mounting bracket 50 are provided with matching processing molds 7; considering that the track parameter requirements of different batches are different, the processing molds 7 used are also different. Therefore, instead of directly fixing the processing molds 7 to the first irregular mounting bracket 40 and the second irregular mounting bracket 50, a detachable connection method is used to fix the processing molds 7.

[0038] Specifically, the track roller press 3 is provided with a matching roller press output track 30 at one end near the six-axis robot 2, and the roller press output track 30 is provided with scale lines; the track roller press 3 is provided with a roller press output track 30 for feeding materials, and scale lines are provided on the roller press output track 30 to facilitate real-time detection by the operator.

[0039] Specifically, the discharge port 100 is provided with a matching good product frame 101, and a matching defective product frame 31 is provided near the track roller press 3; the workstation places the good product frame 101 and the defective product frame 31 to collect good and defective products, so as to facilitate the subsequent transfer of good and defective products.

[0040] 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.
