Description

Technical Field

[0001] This utility model belongs to the field of shot peening technology, and more specifically, it relates to a robotic flexible wheel shot peening machine using tungsten gold spherical shot. Background Technology

[0002] When machining the flexible wheels of a robot, shot peening is required. Shot peening is a strengthening treatment that can double the lifespan of the workpiece. For flexible wheels, shot peening can be achieved by using high-strength tungsten gold spherical shot.

[0003] Based on the above, the shot peening methods currently used in shot peening machines mainly employ clamping structures for positioning, which have many blind spots, making it inconvenient to fully process the working surface of the flexible wheel, and also making it difficult to quickly pick up and put away the shot. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a robotic flexible wheel shot peening machine using tungsten gold spherical shot, which solves the problems mentioned in the background art that the existing shot peening machine uses a positioning mechanism mainly based on a clamping structure, which has many dead angles, making it inconvenient to completely process the working surface of the flexible wheel, and making it difficult to quickly pick up and put down the shot.

[0005] The purpose and effectiveness of this utility model's robotic flexible wheel shot peening machine using tungsten gold spherical shot are achieved through the following specific technical means:

[0006] A robotic flexible wheel shot peening machine using tungsten gold spherical shot includes a shot peening machine. Four sets of shot peening nozzles are installed on the lower rear side of the shot peening machine, each with a spray pipe connected above it. The nozzle opening is located inside the upper part of the shot peening machine. A rotating door is hinged to the front side of the shot peening machine, and a rotary lock for closing the rotating door is also installed above the front side of the shot peening machine. An assembly frame is slidably mounted on the rear side of the rotating door along a guide rail. The main body of the assembly frame is L-shaped, with an open structure in the middle front. A blow-proof plate is fixedly installed on the front side of the open structure. Four sets of workpiece seats are rotatably mounted on the upper rear side of the assembly frame with bearings. A control piston is fixedly installed at the bottom of each workpiece seat at the lower pivot. A positioning post is fixedly installed on the top of each workpiece seat. Four sets of inner support plates are installed outside the positioning post. An airbag is installed inside the positioning post, with the bottom of the airbag connected to the control piston. The outside of the airbag is fixed to the inner side of the inner support plate. When the airbag inflates, it extends the four sets of inner support plates.

[0007] Furthermore, the rear side of the revolving door is provided with a lead screw driven by a motor, and the front middle side of the assembly frame is provided with a nut that is threadedly connected to the lead screw.

[0008] Furthermore, the upper and lower edge distances of the blowout shield are 1.5 times the movable distance of the assembly frame.

[0009] Furthermore, a linkage shaft is rotatably arranged below the assembly frame, and a drive motor is fixedly arranged on the bottom side of the assembly frame, with the drive motor being connected to the linkage shaft for transmission; a transmission shaft is rotatably arranged at the bottom of the assembly frame, with the front end of the transmission shaft being connected to the linkage shaft by a bevel gear transmission, and the rear end of the transmission shaft being connected to the lower rotating shaft of the workpiece seat by a bevel gear transmission.

[0010] Furthermore, four sets of cylinders are fixedly installed below the assembly frame. The extension and retraction ends of the cylinders are rotatably connected to the extension and retraction ends of the control pistons by bearings. When the cylinders extend, the control pistons retract.

[0011] Furthermore, each cylinder is equipped with a solenoid valve at its bottom; an air pump is fixedly installed at the bottom of the assembly frame, and the air pump is connected to a branch pipeline with the solenoid valve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up positioning posts, a function of quickly positioning the flexible wheel is provided. An air pump supplies air to the cylinder, which is then used to open the cylinder. The cylinder compresses the control piston, and the air inside the control piston is input into the internal air bladder of the positioning post. This opens the inner support plate outward and fits against the inner wall of the flexible wheel. The air pressure is used to fix the flexible wheel, making the control convenient and stable, and it can maintain positioning during the rotation of the flexible wheel.

[0014] The linkage shaft can provide a synchronous rotation drive effect. The drive motor is started to drive the linkage shaft to rotate. The linkage shaft, together with the bevel gear, drives the transmission shaft to rotate. The transmission shaft, together with the bevel gear, drives the workpiece seat to rotate, so that the flexible wheel rotates synchronously. At this time, the shot peening device is used to spray tungsten gold balls to impact the surface of the flexible wheel, strengthen the flexible wheel, and achieve shot peening during the rotation of the flexible wheel.

[0015] The shot peening height can be adjusted by rotating the lead screw driven by the motor, which in turn moves the assembly frame up and down. The shot peening shield can withstand impacts and prevent shot from hitting the lead screw. The upper and lower edge distances of the shot peening shield are 1.5 times the movable distance of the assembly frame, which ensures that the lead screw and guide rail can be protected no matter where the shot peening shield is moved.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a robotic flexible wheel shot peening machine using tungsten gold spherical shot, including a shot peening machine 1. Four sets of shot peening nozzles 2 are arranged on the lower rear side of the shot peening machine 1, and each shot peening nozzle 2 is connected to a spray pipe 201. The nozzle opening of the spray pipe 201 is located inside the upper part of the shot peening machine 1. A rotating door 3 is hinged to the front side of the shot peening machine 1, and a rotating lock for closing the rotating door 3 is also provided on the upper front side of the shot peening machine 1. An assembly frame 4 is slidably arranged on the rear side of the rotating door 3 with a guide rail. The main body of the assembly frame 4 is L-shaped, and the middle front side of the assembly frame 4 is open. The structure has a blowout shield 401 fixedly installed on the front side of the open structure; four sets of workpiece seats 5 are rotatably installed on the upper rear side of the assembly frame 4 in conjunction with the bearing, and a control piston 501 is fixedly installed at the bottom of the rotating shaft of each workpiece seat 5; a positioning post 502 is fixedly installed on the top of each workpiece seat 5, and four sets of inner support plates 503 are installed outside the positioning post 502. An airbag is installed inside the positioning post 502, and the bottom of the airbag is connected to the control piston 501. The outside of the airbag is fixed to the inner side of the inner support plate 503. When the airbag expands, it extends the four sets of inner support plates 503.

[0027] The rear side of the revolving door 3 is equipped with a lead screw 301 driven by a motor, and the front middle side of the assembly frame 4 is equipped with a nut that is threadedly connected to the lead screw 301.

[0028] Among them, the top and bottom edge distances of the blowout shield 401 are 1.5 times the movable distance of the assembly frame 4.

[0029] The assembly frame 4 has a linkage shaft 402 rotatably mounted below it, and a drive motor 403 is fixedly mounted on the bottom side of the assembly frame 4. The drive motor 403 is connected to the linkage shaft 402. The bottom of the assembly frame 4 has a drive shaft 404 rotatably mounted below it. The front end of the drive shaft 404 is connected to the linkage shaft 402 by a bevel gear, and the rear end of the drive shaft 404 is connected to the lower rotating shaft of the workpiece seat 5 by a bevel gear.

[0030] Four sets of cylinders 6 are fixedly installed below the assembly frame 4. The extension and retraction ends of the cylinders 6 are rotatably connected to the extension and retraction ends of the control piston 501 by bearings. When the cylinders 6 extend, the control piston 501 retracts.

[0031] Each cylinder 6 is equipped with a solenoid valve 7 at its bottom; an air pump 8 is fixedly installed at the bottom of the assembly frame 4, and the air pump 8 is connected to the solenoid valve 7 via a branch pipeline.

[0032] like Figure 1-5 As shown, the rotating door 3 is unfolded forward, then a flexible wheel is fitted over the positioning pile 502, and then the rotating door 3 is closed; a support structure is pre-installed on the front side of the shot peening machine 1 to ensure that the rotating door 3 is placed flat. Figure 2 The state;

[0033] An exhaust mechanism is installed above the shot peening machine 1, and a recovery mechanism is installed below the shot peening machine 1;

[0034] During operation, the solenoid valve 7 is opened, and the air pump 8 supplies air to the cylinder 6, which is then opened. The cylinder 6 compresses the control piston 501, and the air in the control piston 501 is input into the internal air bladder of the positioning post 502, which opens the inner support plate 503 outward and fits against the inner wall of the flexible wheel. The flexible wheel is fixed by air pressure. The opening of the solenoid valve 7 depends on whether the flexible wheel is installed. If only three sets of flexible wheels are installed, the solenoid valve 7 associated with the positioning post 502 without flexible wheels will be closed, and the corresponding shot peening machine 2 will not be activated.

[0035] The drive motor 403 is started to drive the linkage shaft 402 to rotate. The linkage shaft 402, in conjunction with the bevel gear, drives the transmission shaft 404 to rotate. The transmission shaft 404, in conjunction with the bevel gear, drives the workpiece seat 5 to rotate, so that the flexible wheel rotates synchronously. At this time, the shot peening device 2 is used to spray tungsten gold balls to impact the surface of the flexible wheel, strengthen the flexible wheel, and achieve shot peening during the rotation of the flexible wheel.

[0036] The screw 301 is driven to rotate by a motor, and the screw 301 drives the assembly frame 4 to move up and down, which can adjust the shot peening height. The anti-blast plate 401 can withstand the impact and prevent shot from impacting the screw 301.

[0037] Example 2:

[0038] Based on Example 1, an electric cylinder can be used to automatically control the opening and closing of the revolving door 3, replacing the revolving lock, to achieve automatic opening and closing;

[0039] During the rotation of the rotating door 3, some of the tungsten gold pellets remaining on the surface of the assembly rack 4 can be removed by the inclined surface, allowing the pellets to fall into the recycling mechanism.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In this utility model, during assembly, according to... Figure 2 In this state, the revolving door 3 is opened forward, then a flexible wheel is placed over the positioning post 502, and then the revolving door 3 is closed;

[0042] Open the solenoid valve 7, use the air pump 8 to supply air to the cylinder 6, expand the cylinder 6, and then use the cylinder 6 to compress the control piston 501, input the air in the control piston 501 into the internal air bag of the positioning post 502, expand the inner support plate 503 outward, fit against the inner wall of the flexible wheel, and use air pressure to fix the flexible wheel.

[0043] The drive motor 403 is started to drive the linkage shaft 402 to rotate. The linkage shaft 402, in conjunction with the bevel gear, drives the transmission shaft 404 to rotate. The transmission shaft 404, in conjunction with the bevel gear, drives the workpiece seat 5 to rotate, so that the flexible wheel rotates synchronously. At this time, the shot peening device 2 is used to spray tungsten gold balls to impact the surface of the flexible wheel, strengthen the flexible wheel, and achieve shot peening during the rotation of the flexible wheel.

[0044] The screw 301 is driven to rotate by a motor, and the screw 301 drives the assembly frame 4 to move up and down, which can adjust the shot peening height. The anti-blast plate 401 can withstand the impact and prevent shot from impacting the screw 301.
