Description

Technical Field

[0001] This utility model belongs to the field of machining, and specifically relates to an adjustable angle shot peening nozzle. Background Technology

[0002] Shot peening is a surface treatment method that uses small, hard shot to impact a metal surface for cold working. Shot peening strengthening refers to the use of moving shot to impact a metal surface, causing a plastic strain layer on the metal surface. This results in beneficial changes in the microstructure of this layer (refining the microstructure of the surface metal) and introducing a residual compressive stress layer on the surface. This residual stress layer can improve the fatigue fracture and stress corrosion cracking resistance of metal parts, thereby improving the fatigue life and stress corrosion resistance of the parts.

[0003] During shot peening, different nozzles are needed to target the peening area due to varying angles and intensities on different surfaces. Existing nozzles for shot peening, whether fixed or structurally composite, are specialized nozzles designed for the specific structural characteristics of each product. Throughout the shot peening process, nozzle changes consume significant production preparation time, impacting equipment operating efficiency, limiting output, and increasing manufacturing costs. Utility Model Content

[0004] This invention provides a novel shot peening nozzle with an adjustable angle, which satisfies the needs for adjusting and detecting the shot peening angle during the shot peening process.

[0005] An adjustable-angle shot peening nozzle includes a connecting pipe, an adjustable steering device, and a steering quick-change nozzle connected in sequence. The adjustable steering device includes an outer annular shell and an inner annular base. The annular shell has a through first insertion hole and a first waist-shaped hole in the circumferential direction on its annular surface. The connecting pipe is connected through the first insertion hole. The annular shell has circular scales on its two end faces. The annular base has a through second insertion hole and a second waist-shaped hole in the circumferential direction on its annular surface. A sensing patch is embedded in the inner annular surface. The steering quick-change nozzle passes through the first waist-shaped hole and is connected through the second insertion hole. The first insertion hole is within the angle range of the second waist-shaped hole.

[0006] Advantageously or alternatively, the steering quick-change nozzle includes a two-section structure: an inner structure that is a nozzle that is connected in passage to the second insertion hole, and an outer structure that is a catapult structure with an inclined surface that forms an angle with the axis of the nozzle.

[0007] Advantageously or alternatively, the upper end of the connecting pipe is connected to the shot peening machine.

[0008] Advantageously or alternatively, the sensing patch is used to collect instantaneous pellet flow rate.

[0009] Advantageously or alternatively, the angle between the connecting pipe and the steering quick-change nozzle is adjustable.

[0019] The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. In fact, many different examples may be described, and these examples should not be construed as limited to those set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0020] like Figure 1 This utility model discloses an adjustable-angle shot peening nozzle comprising a connecting pipe 1, an adjustable steering device 2, and a quick-change steering connector 3. The connecting pipe 1, serving as a quick-change device between the adjustable steering device 2 and the shot peening machine, is a rotating tubular structure, with its upper end connected to the shot peening machine and its lower end connected to the adjustable steering device 2. The adjustable steering device 2 includes an annular housing 10 and circular dials 8 on both sides. The annular housing 10 has a through first insertion hole 12 and a circumferentially oriented first waist-shaped hole 11 on its annular surface. The connecting pipe 1 is installed in the first insertion hole 12.

[0021] See Figure 2 The adjustable steering device 2 has an embedded structure with a ring-shaped base. The ring surface has a through second insertion hole 9 and a second waist-shaped hole 4 in the circumferential direction. The inner ring surface has an embedded induction patch 5. The function of the induction patch 5 is to collect the instantaneous pellet flow rate and effectively implement the pellet flow rate through secondary feedback from the sensor.

[0022] See Figure 3 The quick-change steering nozzle 3 comprises two sections: an inner nozzle 7 and an outer ejector structure 6. The ejector structure 6 has an inclined surface at a certain angle to the axis of the nozzle 7. The nozzle 7 is connected to the second insertion hole 9. When the angle between the connecting pipe 1 and the quick-change steering nozzle 3 is adjusted, the nozzle 7 rotates within the arc range of the first waist-shaped hole 11, and the first insertion hole 12 rotates within the arc range of the second waist-shaped hole 4.

[0023] The adjustable steering device 2 enables quick interchange and rapid assembly of the required nozzle. Angle markings on the circular end face effectively control the spray intensity and monitor the nozzle angle. This adjustable steering device 2 maximizes both "quick interchange" and "versatility." After assembling the nozzle according to the product structure, shot peening can be performed on the product, allowing for shot peening at various angles and ensuring the accuracy of the shot peening process.

[0024] This utility model tool utilizes a connecting pipe in conjunction with an adjustable steering device and a quick-change steering nozzle. The adjustable steering device allows for easy replacement of the nozzle or connecting pipe based on the size and characteristics of the shot peening area, fully demonstrating the versatility and quick-change capability of the shot peening nozzle. The nozzle itself is angle-adjustable, providing feedback on the actual spray angle, and transmits shot flow rate data via a sensor for monitoring the shot peening process. The nozzle's angle adjustment design and optimized nozzle channel design, along with the inclusion of a buffer sensing area, enable the nozzle to intelligently collect process data. This utility model saves production costs and product preparation time during production preparation and process inspection, improving equipment operating efficiency to a certain extent and achieving the goal of cost reduction and efficiency improvement in aircraft product manufacturing. Specifically, it is applied to the surface shot peening strengthening of small and medium-sized frame beam products.
