Description

Technical Field

[0001] This invention relates to the field of shot peening technology, specifically to a CNC shot peening machine with a steel belt shaft. Background Technology

[0002] The principle of shot peening is to use the impact of a high-speed shot stream on the metal surface to create a plastic cyclic strain layer on the surface. This causes beneficial changes in the microstructure of the layer and introduces a residual compressive stress field into the surface layer. The microstructure and residual compressive stress field of the surface layer are two strengthening factors that improve the fatigue fracture and stress corrosion (including hydrogen embrittlement) fracture resistance of metal parts. As a result, the reliability and durability of the parts are improved.

[0003] Shot peening the surface of steel belt shafts can significantly increase the surface roughness, thereby increasing the friction coefficient of the main machine during braking and reducing slippage during elevator braking. Traditional shot peening of steel belt shafts is highly dependent on manual labor. Workpiece handling, fixture adjustment, flipping for shot peening, and offline inspection all require manual operation, which is inefficient and prone to collision damage (damage rate ≥3%). Uneven coverage is easily caused during shot peening, especially in grooves and edges, which often require secondary shot peening. During inspection, the workpiece must be removed and sent to the offline inspection room, with each inspection taking about 2 hours, interrupting the production flow. Summary of the Invention

Multi-angle adjustable nozzles combined with real-time feedback from inspection styluses ensure uniform shot peening of the steel strip shaft surface (roughness Ra value controllable to 3.2μm), effectively enhancing the material's fatigue resistance (extending service life by 20%-30%). Based on online inspection data, shot peening parameters (such as nozzle angle and movement speed) are optimized in real time, achieving a surface roughness consistency of 98% (compared to ≤85% in traditional processes), completely eliminating rework issues.

[0036] Please see Figure 1 - Figure 12 The present invention provides an embodiment of a CNC shot peening machine for steel belt shafts. CNC shot peening of steel belt shafts is an advanced process for surface strengthening and cleaning of shaft workpieces (such as steel belt shafts) using high-precision CNC equipment. It is widely used in machinery manufacturing, automobiles, aerospace and other fields. The core equipment is the shot peening system, which uses compressed air to spray shot onto the surface of the workpiece. Specifically, it includes:

[0037] Two material-carrying mechanisms 1 are provided. One of the material-carrying mechanisms 1 is used for the automatic transport of steel strip shafts prepared for shot peening, while the other material-carrying mechanism 1 is used for the transport of steel strip shafts after processing. In order to accommodate steel strip shafts of different lengths, each material-carrying mechanism 1 can adjust the transmission width.

[0038] The transport and inspection unit 2 is used for loading steel strip shafts. It loads and transports steel strip shafts that need to be shot-peened to the shot-peening processing area, and can also perform precision inspection on the surface of the steel strip shafts after shot-peening.

[0039] The multi-axis robotic arm 3 moves and installs the steel strip shaft that is to be shot peened in the transport and inspection mechanism 2, and at the same time removes the steel strip shaft after shot peening from the transport and inspection mechanism 2 and moves it to the material receiving mechanism 1.

[0040] Track 4 serves as a transport track, and the transport and inspection mechanism 2 is installed on track 4. The end of track 4 extends into the shot peening processing area of ​​shot peening mechanism 5. The installation of the steel belt shaft by the multi-axis robotic arm 3 is also completed on track 4.

[0041] The shot peening mechanism 5 performs multi-angle shot peening on the surface of the steel belt shaft.

[0042] It is worth mentioning that, in this embodiment, the material-bearing mechanism 1 includes a housing 101, a bracket 102 is fixedly installed at the bottom of the inner cavity of the housing 101, three horizontal plates 105 are fixedly installed on the bracket 102, and chain drive modules 103 are respectively installed on the bracket 102 and the horizontal plates 105. Several triangular groove plates 104 are equidistantly installed on the chain drive module 103. One of the chain drive modules 103 is fixed to the bracket 102, and the other chain drive module 103 is fixed to the bracket 102. The moving module 103 is slidably connected to the horizontal plate 105 via the slide 106, and a connecting block 107 is fixedly connected to its bottom. A lead screw 108 is rotatably installed between the left and right side walls of the housing 101. The lead screw 108 is threadedly connected to the connecting block 107. Rotating the lead screw 108 allows the chain drive module 103 on one side to slide, thereby adjusting the distance between the two chain drive modules 103. The two ends of the steel belt shaft are respectively clamped onto the triangular groove plates 104 on both sides.

[0043] It is also worth mentioning that, in this embodiment, the transport inspection mechanism 2 includes a second housing 202, on which two connecting slide plates 203 are installed. Each connecting slide plate 203 is slidably mounted on the track 4. An adjustable clamping fixture 1 205 and a fixed clamping fixture 206 are installed on the connecting slide plate 203. The clamping fixture 1 205 and the clamping fixture 206 are used to fix the steel belt shaft. A power housing 207 is fixedly installed on the connecting slide plate 203, and a [missing information - likely a component or component] is fixedly installed inside the power housing 207. Servo motor 212 and servo motor 213 are provided. The output end of servo motor 213 is poweredly connected to the drive end of clamping fixture 206, one type of power connection being a belt drive connection. Servo motor 212 is vertically mounted on the connecting slide plate 203, and its output end passes through the bottom of the connecting slide plate 203. A gear installed at the output end can mesh with a rack installed on the track 4 to form a transmission, thereby driving the connecting slide plate 203 to move on the track 4. A base frame is provided on the front side of the chassis 202. 201. A second bracket 208 is fixedly installed on the base frame 201. A multi-axis moving assembly 209 is fixedly installed on the second bracket 208. A main body detection unit 210 is fixedly installed on the multi-axis moving assembly 209. A detection stylus 211 is installed on the main body detection unit 210. The multi-axis moving assembly 209 drives the detection stylus 211 to perform precision detection on the surface of the steel strip shaft after shot peening, including surface roughness detection. The multi-axis robotic arm 3 places the steel strip shaft to be shot peened into clamping fixture 1 205 and clamping fixture 2. Between 206, firstly, the servo motor 213 drives the clamping fixture 206 to clamp one end of the steel strip shaft, while the other end is clamped by the clamping fixture 205. After clamping, the steel strip shaft can be rotated by the servo motor inside the clamping fixture 205. After the steel strip shaft is clamped, the servo motor 212 drives the steel strip shaft to the shot peening area of ​​the shot peening mechanism 5 for shot peening. After shot peening, it is reset, and the surface roughness of the steel strip shaft is detected by the detection stylus 211 to achieve fully automated processing and inspection. After the inspection is completed, the multi-axis robotic arm 3 is used to pick up the steel strip shaft.

[0044] It should be noted that, in this embodiment, the connecting slide plate 203 is provided with a through adjustment groove 204, and the clamping fixture 205 is adjustablely slidably installed in the adjustment groove 204, so that steel strip shafts of different lengths can be processed accordingly.

[0045] It is also worth mentioning that, in this embodiment, the multi-axis robotic arm 3 includes a robotic arm body 301. The execution end of the robotic arm body 301 is fixedly installed with a clamping and fixing chamber 302. The lower end face of the clamping and fixing chamber 302 is fixedly installed with connecting plates 303 on the left and right sides respectively. The lower end of each connecting plate 303 is fixedly installed with a guide post 304. The lower end of the guide post 304 is slidably connected with an electromagnet 305. An elastic reset member is connected between the upper end of the electromagnet 305 and the lower end of the connecting plate 303. The elastic reset member can be a compression spring, which is sleeved on the guide post 304. The lower end face of the electromagnet 305 is fixedly installed with an adsorption gripping part 306. The adsorption gripping part 306 is used to grip the steel strip shaft.

[0046] In another embodiment, the shot peening mechanism 5 includes a main control box 501, a recovery area 502, and a shot peening area 503. The track 4 extends into the inner cavity of the shot peening area 503. A connecting plate portion 516 is slidably installed on the top of the shot peening area 503. Shot peening fixing plates 506 are fixedly installed at both ends of the connecting plate portion 516. A through groove 517 is provided through the top of the shot peening area 503. Each shot peening fixing plate 506 is slidably connected to the corresponding through groove 517. A strip-shaped hole 507 is provided on the shot peening fixing plate 506. A fixing part 508 is installed in the strip-shaped hole 507. An arc-shaped mounting part 509 is fixedly installed on the fixing part 508. Shot peening nozzles 5 are respectively installed on the fixing part 508 and the arc-shaped mounting part 509. 10. One shot peening nozzle 510 is fixed on the fixing part 508, while the other shot peening nozzle 510 is adjustablely mounted on the arc-shaped mounting part 509. This allows the angle to be adjusted according to the shape of the steel strip shaft. Multiple shot peening nozzles 510 can also be mounted on the arc-shaped mounting part 509 as needed to achieve multi-angle shot peening. A servo drive is used to drive the connecting plate part 516 to reciprocate, thereby driving the shot peening nozzles 510 to reciprocate and perform shot peening on the steel strip shaft. Simultaneously, a dust suction hood 514 is fixedly mounted on the shot peening fixing plate 506. The top of the dust suction hood 514 is connected to an external dust collection device through a pipe, thus constantly adsorbing and removing dust generated during the shot peening process, preventing excessive dust from affecting the shot peening.

[0047] It should be noted that a funnel section 511 is provided in the recycling area 502. A perforated plate 512 is fixedly installed between the upper end of the funnel section 511 and the shot peening area 503. A recycling frame 515 is installed at the bottom outlet of the funnel section 511. The processed shot falls into the funnel section 511 through the perforated plate 512 and is collected. Finally, it can be recycled by opening the outlet at the bottom of the funnel section 511.

[0048] In another embodiment, a porous cover 504 is fixedly installed at the opening position on one side of the track 4 in the shot peening area 503.

[0049] In actual operation, take a steel belt shaft with a length of 1.5 meters as an example;

[0050] The worker places the steel strip shaft to be shot-peened on the triangular groove plate 104 of the left-side material receiving mechanism 1 as preparation for shot peening. After the previous steel strip shaft has been shot-peened, the multi-axis robotic arm 3 moves to the left-side material receiving mechanism. The adsorption gripping part 306 descends, energizing the electromagnet 305 to adsorb the steel strip shaft. At this time, the elastic reset part buffers the contact impact. The robotic arm body 301 transfers the steel strip shaft to the transport and detection mechanism 2 on the track 4. The steel strip shaft is placed between clamping fixture one 205 (slidable) and clamping fixture two 206 (fixed end) for clamping and fixing. Inside clamping fixture one 205, a drive motor for rotating the steel strip shaft is installed. After the steel strip shaft is installed between clamping fixture one 205 and clamping fixture two 206, the drive motor can make the steel strip shaft rotate, thereby facilitating shot peening. For shot blasting and subsequent surface precision inspection, the steel belt shaft is transferred to the shot blasting area 503. The shot blasting nozzles 510 are adjusted according to the diameter of the steel belt shaft: the nozzles of the fixing part 508 are fixed, and the nozzle angle of the arc-shaped mounting part 509 is adjustable (e.g., tilted 30° to cover the groove). The servo drive drives the connecting plate part 516 to move back and forth, thereby driving the shot blasting fixing plate 506 to slide along the through groove 517 so that the multi-angle nozzles 510 cover the entire surface of the steel belt shaft. Simultaneously, the dust is started to discharge the dust generated by shot blasting through the dust suction hood 514 and the pipe to keep the working environment clean. The shot blasting residue falls into the funnel part 511 through the mesh plate 512 and is then collected and processed by the recycling frame 515. The traditional fixed nozzle coverage rate is less than 60%, and manual turning is required. This solution achieves 95% dynamic multi-angle coverage, and dust removal reduces equipment wear.

[0051] After shot peening, the transport and inspection mechanism 2 returns to its original position. The multi-axis moving component 209 on the bracket 208 drives the inspection stylus 211 to contact the surface of the steel strip shaft and collect surface roughness data (such as Ra value) in real time. The data is transmitted to the main control system. If it is qualified (such as Ra≤1.6μm), it enters the unloading process; if it is unqualified, an alarm is triggered. Traditionally, it needs to be removed and sent to the inspection room for offline inspection, which takes 2 hours. In this solution, online inspection takes ≤5 minutes. The multi-axis robotic arm 3 picks up the inspected steel strip shaft and moves it to the right-side material receiving mechanism 1. The right-side material receiving mechanism outputs the finished shaft to the next process (such as painting). The cycle starts, and the left-side material receiving mechanism loads new workpieces simultaneously to achieve continuous production.

[0052] The shot peening parameters (such as nozzle angle and moving speed) of this invention can be optimized in real time based on detection feedback, forming a "processing-inspection-correction" closed loop. A steel belt shaft with a length of 1.5m and a diameter of 80mm can be shot peened and inspected in just 8 minutes from loading (the traditional process takes more than 105 minutes), and the surface roughness consistency reaches 98%, which significantly improves the mass production capacity and yield of high-end shaft parts.

[0053] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the invention. Therefore, the scope of protection of the invention should be determined by the scope defined in the claims.
