Description

Technical Field

[0001] This utility model belongs to the field of shot peening technology, specifically relating to a shot peening device for mechanical parts. Background Technology

[0002] Shot peening equipment is a specialized device used to strengthen the surface of metal mechanical parts by shot peening. It uses a large number of small shot at high speed to impact the surface of the workpiece, causing plastic deformation of the surface metal. This deformation will generate a beneficial residual compressive stress layer below the surface. The residual compressive stress can effectively offset the alternating tensile stress that the parts are subjected to during service, significantly delay the initiation and propagation of fatigue cracks, and greatly improve the fatigue life of the parts.

[0003] In the prior art, for example, the invention disclosed by patent number CN211517175U is a shot peening device for machining mechanical parts, which includes a device shell, shot peening nozzles, fixing frames, control switches and servo motors. The fixing frames are connected to the inner walls of the left and right sides of the device shell, and the shot peening nozzles are hinged inside the fixing frames.

[0004] During operation, the projectiles sprayed from the nozzles tend to fall into the chute and accumulate. Since they cannot be automatically recovered or cleaned, the machine must be stopped for processing, which not only increases the workload but also affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a shot peening device for mechanical parts, which can realize the real-time collection of shot falling into the slide rail through an automatic recovery device, effectively reducing manual intervention and improving work efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A shot peening device for mechanical parts includes a working box, which is divided into an upper layer and a lower layer. A rotating door is axially connected to the side wall of the upper layer. A support plate is installed on the inner side wall of the rotating door. A slide rail is provided on the support plate. A turntable is movably installed on the slide rail. A fixing device is provided on the turntable.

[0008] The fixing device includes circumferentially spaced grooves on the turntable, each groove having an inclined bottom surface. Each groove contains a sliding frame with a slider at its bottom. The slider's bottom is inclined at the same angle as the groove's bottom surface. A spring is mounted on the upper surface of the slider, and a fixing rod is fixedly connected to the other end of the spring. The upper end of the fixing rod passes through the groove, and a toothed block is provided at its bottom. A rack is provided on the lower wall of the upper end of the groove, and the toothed block meshes with the rack.

[0009] Preferably, a drive motor is mounted on the bottom surface of the support plate, and the output end of the drive motor is connected to the turntable.

[0010] Preferably, the upper end of the fixing rod is provided with a rubber strip.

[0011] Preferably, a bracket is installed on the inner wall of the working box, and a nozzle is installed on the bracket.

[0012] Preferably, the upper bottom surface of the working box has multiple circular holes, the diameter of which is larger than the diameter of the projectile ejected from the nozzle.

[0013] Preferably, the lower layer of the work box is provided with a pull-out box.

[0014] Preferably, the nozzle inlet end is connected to a spray pipe, and the other end of the spray pipe is connected to a shot peening machine.

[0015] The technical effects achieved by this utility model are as follows:

[0016] In this invention, the chute not only assists in adjusting the distance between the fixing devices to accommodate workpieces of different sizes, but also discharges the projectiles that fall into it. Specifically, the projectiles ejected from the nozzles fall into the pull-out box through the provided circular holes. Even if the projectiles fall into the chute, due to the inclined bottom surface of the chute, they will roll down the slope to the upper bottom surface of the work box, and then fall into the pull-out box through the circular holes, thus completing the collection of the projectiles. The automatic recovery device enables real-time collection of projectiles falling into the chute, effectively reducing manual intervention and improving work efficiency. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] A shot peening device for mechanical parts includes a working box 1, which is divided into an upper layer and a lower layer. A rotating door 2 is axially connected to the side wall of the upper layer. A support plate 3 is installed on the inner side wall of the rotating door 2. A slide rail 4 is provided on the support plate 3. A turntable 5 is movably installed on the slide rail 4. A fixing device 6 is provided on the turntable 5.

[0025] The fixing device 6 includes circumferentially spaced grooves 601 on the turntable 5. The bottom surface of each groove 601 is inclined. A sliding frame 602 is provided in each groove 601. A slider 603 is provided at the bottom of the sliding frame 602. The bottom of the slider 603 is inclined. The inclination angle of the bottom of the slider 603 is the same as the inclination angle of the bottom surface of the groove 601. A spring 604 is installed on the upper surface of the slider 603. A fixing rod 605 is fixedly connected to the other end of the spring 604. The upper end of the fixing rod 605 passes through the groove 601. A toothed block 606 is provided at the bottom end of the fixing rod 605. A rack 607 is provided on the lower wall of the upper end of the groove 601. The toothed block 606 meshes with the rack 607.

[0026] Preferably, a drive motor 7 is installed on the bottom surface of the support plate 3, and a turntable 5 is connected to the output end of the drive motor 7.

[0027] like Figures 1-4 As shown: In practical applications, shot peening equipment is a specialized device used for shot peening and strengthening the surface of metal mechanical parts. It uses high-speed jets of numerous small shot pellets to impact the workpiece surface, causing plastic deformation of the surface metal. During operation, the rotating door 2 is opened, and the part to be processed is placed on the turntable 5. The fixing device 6 is initially in the following state: Figure 4 As shown, when fixing the part to be processed, press down on the fixing rod 605 to disengage the toothed block 606 from the rack 607. At this time, the spring 604 is compressed and stores energy, and moves the fixing rod 605 horizontally, driving the slider 603, the slide frame 602 and the spring 604 to move synchronously to the target clamping position. Release the fixing rod 605, and the spring 604 rebounds to push the toothed block 606 to mesh with the rack 607, realizing the axial locking of the fixing rod 605. At the same time, the spring 604 presses down on the slider 603, so that it is in contact with the bottom surface of the slide groove 601. Since the bottom of the slider 603 and the bottom surface of the slide groove 601 have the same inclination angle, the slider 603 can slide freely in the slide groove 601, ensuring clamping flexibility.

[0028] Preferably, the upper end of the fixing rod 605 is provided with a rubber strip 8.

[0029] like Figures 1-4As shown: The rubber strip 8 provided at the upper end of the fixing rod 605 can not only effectively prevent the surface of the workpiece from being damaged during the clamping process, but also increase the friction between the fixing rod 605 and the workpiece, ensuring the stability of the clamping.

[0030] Preferably, a bracket 9 is installed on the inner wall of the working box 1, and a nozzle 10 is installed on the bracket 9.

[0031] Preferably, the upper bottom surface of the working box 1 has multiple round holes, the diameter of which is larger than the diameter of the projectile ejected by the nozzle 10.

[0032] Preferably, the lower layer of the work box 1 is provided with a pull-out box 11.

[0033] like Figures 1-4 As shown: the projectiles ejected from the nozzle 10 can fall into the pull-out box 11 through the set round hole. Even if the ejected projectiles fall into the slide 601, due to the inclined bottom surface of the slide 601, the projectiles will roll down the inclined surface to the upper bottom surface of the working box 1, and then fall into the pull-out box 11 through the round hole, thus completing the collection of the projectiles.

[0034] In this invention, the slide 601 can not only help adjust the distance between the fixing devices 6 to adapt to workpieces of different sizes, but also discharge the projectiles that fall into the slide 601.

[0035] Preferably, the nozzle 10 is connected to a spray pipe at its inlet end, and the other end of the spray pipe is connected to a shot peening machine 12.

[0036] like Figures 1-4 As shown: The shot peening machine 12 is specifically responsible for providing the shot medium required for the shot peening process. Its internal system filters and accelerates the stored shot through preset pressure parameters, and delivers it stably and continuously to the nozzle 10 through a specific conveying pipeline. This ensures that the blasting process has a sufficient and controllable shot supply.

[0037] The working principle of this utility model is as follows: During operation, the rotating door 2 is opened, the part to be processed is placed on the turntable 5, and the fixing device 6 is in its initial state, such as... Figure 4 As shown, when fixing the part to be processed, press down on the fixing rod 605 to disengage the toothed block 606 from the rack 607. At this time, the spring 604 is compressed and stores energy, and moves the fixing rod 605 horizontally, driving the slider 603, the slide frame 602 and the spring 604 to move synchronously to the target clamping position. Release the fixing rod 605, and the spring 604 rebounds to push the toothed block 606 to mesh with the rack 607, realizing the axial locking of the fixing rod 605. At the same time, the spring 604 presses down on the slider 603, so that it is in contact with the bottom surface of the slide groove 601. Since the bottom of the slider 603 and the bottom surface of the slide groove 601 have the same inclination angle, the slider 603 can slide freely in the slide groove 601, ensuring clamping flexibility.

[0038] The projectiles ejected from the nozzle 10 can fall into the pull-out box 11 through the round hole. Even if the projectiles fall into the slide 601, the projectiles will roll down the slope to the bottom of the upper layer of the working box 1 due to the inclined bottom surface of the slide 601, and then fall into the pull-out box 11 through the round hole, thus completing the collection of the projectiles.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
