[0023] As shown in Figures 2 and 3A, the treatment tank 15 is placed on the internal conveyor 25 and the external conveyor 29 and guided by the internal guide 23 and the external guide 27. The treatment tank 15 is then carried into the treatment position 81 through the carry-in opening 13a. The treatment tank 15 is also carried out through the carry-in opening 13a to the carry-out position 84. The treatment position 81 is the fixed position of the treatment tank 15 inside the splash cover 13.

The pin confirmation sensor 61 is disposed on the positioning bracket 59. The pin confirmation sensor 61 is, for example, a proximity sensor or a limit switch.

[0025] The recovery manhole 53 is fixed to the frame 11. When the treatment tank 15 is in the treatment position 81, the recovery manhole 53 is located below the discharge port 15d. The recovery manhole 53 recovers the treatment liquid 1 and the abrasive powder 2 that overflow from the treatment tank 15. The treatment liquid 1 and the abrasive powder 2 recovered from the recovery manhole 53 are collected in the tank 54.

[0026] As shown in FIG. 4, the elevator 31 has a lifting frame 31a, a lifting guide 31b, and a lifting cylinder 31c. The lifting frame 31a is fixed to the upper surface of the frame 11 and extends in the vertical direction. The lifting frame 31a is arranged on the side of the pair of internal guides 23 (for example, on the -X side of the -X side guide). The lifting guide 31b is a linear guide. The lifting guide 31b extends in the vertical direction and is arranged on the lifting frame 31a. The lifting cylinder 31c is arranged above the frame 11. The lifting cylinder 31c is a fluid cylinder. The lifting cylinder 31c has a rod 31c1. The rod 31c1 is connected to the lifting box 35. The lifting cylinder 31c extends and retracts the rod 31c1 to raise and lower the lifting box 35. When the treatment tank 15 moves between the treatment position 81 and the unloading position 84 , the treatment tank 15 passes by the side of the elevator 31 .

[0027] As shown in FIGS. 2 and 4, the lift box 35 has a back plate 35a, a bridge 35b, and a box body 35c. The back plate 35a extends along the YZ plane and is disposed on a pair of lift guides 31b. The back plate 35a is located outside the side wall 15b (on the -X side in FIG. 4). The back plate 35a is guided by the lift guides 31b to move up and down. The bridge 35b connects the upper end of the back plate 35a to the top of the box body 35c. The bridge 35b straddles the side wall 15b and extends above the treatment tank 15. The box body 35c has a thin rectangular parallelepiped shape. The box body 35c extends vertically from above the bridge 35b to the height of the lower end of the back plate 35a. The lifting box 35 reciprocates between an elevated position 82 (see FIG. 4) and a lowered position 83 (FIG. 3B) by the lifting cylinder 31c. When the lifting box 35 is at the elevated position 82, the entire box body 35c is positioned above the treatment tank 15. When the lifting box 35 is at the lowered position 83, most of the box body 35c is inserted inside the treatment tank 15. The lower end of the box body 35c is inserted close to the bottom of the treatment tank 15.

[0028] The lifting box 35 has a tilting motor 37, a tilting shaft 41, a bearing 42, a driving pulley 39, a driven pulley 43, and an endless belt 45. The tilting motor 37, the tilting shaft 41, the bearing 42, the driving pulley 39, the driven pulley 43, and the endless belt 45 are disposed inside the box body 35c. The tilt motor 37 is fixed to the upper end of the box body 35c. The driving pulley 39 is connected to the tilt motor 37. The tilt shaft 41 extends along the table pivot axis 5. The tilt shaft 41 is supported at the lower end of the box body 35c via a bearing 42. The table pivot axis 5 extends parallel to the X-axis. The driven pulley 43 is fastened to the tilt shaft 41. The tilt shaft 41 penetrates the wall surface of the box body 35c and protrudes from the box body 35c in the +X direction. The endless belt 45 is attached between the driving pulley 39 and the driven pulley 43. The endless belt 45 is a toothed belt. The tilt motor 37 tilts the table 47 via the driving pulley 39, the driven pulley 43, the endless belt 45, and the tilt shaft 41.

[0029] The table 47 is fastened to the tilting shaft 41 and tilts around the table rotation shaft 5. The table 47 is L-shaped when viewed from the front. The workpiece 3 is placed on the table 47. The table 47 may have a clamp or a positioning pin (not shown). The first agitation nozzle 49 has an agitation pipe 49a and a nozzle 49b. The agitation pipe 49a is connected to the lower end of the box body 35c. The agitation pipe 49a has a vertical portion 49a1 and an annular portion 49a2. The vertical portion 49a1 extends downward from the lower surface of the box body 35c. The annular portion 49a2 is connected to the lower end of the vertical portion 49a1. The annular portion 49a2 makes one revolution along the side wall 15b on the XY plane. The annular portion 49a2 has a regular octagonal shape in plan view. A gap may be provided between the annular portion 49a2 and the side wall 15b. Multiple nozzles 49b are evenly arranged on the lower surface of the annular portion 49a2. The treatment liquid 1 is sprayed downward from the nozzles 49b. The nozzles 49b are arranged directly on the agitation pipe 49a. The vertical portion 49a1 may extend from the side surface of the box body 35c.

[0030] The first agitation nozzle 49 rises and falls integrally with the lifting box 35. As shown in FIG. 3A, when the lifting box 35 is in the raised position 82, the first agitation nozzle 49 is located above the treatment tank 15. As shown in FIG. 3B, when the lifting box 35 is lowered while the treatment tank 15 is in the treatment position 81, the first agitation nozzle 49 is inserted into the treatment tank 15. When the lifting box 35 is in the lowered position 83, the first agitation nozzle 49 is located at the bottom of the treatment tank 15.

[0031] The second agitation nozzle 51 is disposed at the front and rear ends of the table 47. The second agitation nozzle 51 extends in the X direction. The second agitation nozzle 51 is a slit nozzle. The second agitation nozzle 51 has an agitation pipe 51a and a slit (nozzle) 51b. The slit 51b is disposed over approximately 50 to 70% of the overall width of the table 47. The second agitation nozzle 51 sprays air or the processing liquid 1 toward the back surface of the table 47. The slit 51b is disposed directly in the agitation pipe 51a. The air may be supplied from outside the peening apparatus 10. The peening apparatus 10 may also include a blower or an air compressor.

[0032] A method of using the peening apparatus 10 of this embodiment will be described. First, as shown in FIG. 3A, the lifting box 35 is raised to the raised position 82 by the elevator 31. An operator places abrasive powder 2 into the treatment tank 15. Next, the treatment tank 15 is inserted from the carry-out position 84 to the treatment position 81. Here, the treatment tank 15 is guided by the external guide 27 and the internal guide 23 and moved by the external conveyor 29 and the internal conveyor 25. Next, the pin 57 is inserted. The pin confirmation sensor 61 confirms that the pin 57 has been inserted.

[0033] Next, the workpiece 3 is placed on the table 47 by an operator or a robot arm. The low-pressure pump 56 fills the processing tank 15 with the processing liquid 1. Next, as shown in FIG. 3B, the elevator 31 lowers the lifting box 35 to the lowered position 83. The first agitation nozzle 49, the table 47, the second agitation nozzle 51, and the workpiece 3 are immersed in the processing liquid 1. Next, the low-pressure pump 56 sends the processing liquid 1 to the first agitation nozzle 49. The first agitation nozzle 49 sprays the processing liquid 1, causing the abrasive powder 2 to become cloudy in the processing liquid 1. Excess processing liquid 1 is discharged from the overflow port 15c and collected in the tank 54 from the collection manhole 53.

[0034] Next, the slide 18 moves the peening nozzle 19 so as to face the workpiece 3. Here, the peening nozzle 19 is immersed in the processing liquid 1. A high-pressure pump 58 sends the processing liquid 1 to the peening nozzle 19. The peening nozzle 19 sprays the processing liquid 1, and the jet of the processing liquid 1 entrains the abrasive powder 2 and collides with the workpiece 3. Then, the surface of the workpiece 3 is ground by the abrasive powder 2, resulting in a reduction in thickness. Furthermore, the workpiece 3 is peened, and compressive residual stress is imparted to the workpiece 3.

[0035] If necessary, the table 47 is tilted by the tilting motor 37. At this time, the second agitation nozzle 51 sprays air or the processing liquid 1. Even if the abrasive powder 2 has settled on part of the bottom surface of the processing tank 15, the abrasive powder 2 is lifted up by the jet from the second agitation nozzle 51, allowing the table 47 to tilt smoothly.

[0036] Thereafter, the peening nozzle 19 stops spraying. Next, the first agitating nozzle 49 stops spraying. Next, the elevator 31 raises the lift box 35 to the raised position 82.

[0037] Next, the pin 57 is pulled out. The treatment tank 15 moves to the unloading position 84. When the treatment tank 15 is in the unloading position 84, the drain valve 16 is opened and the treatment liquid 1 and the abrasive powder 2 are discharged from the treatment tank 15. An operator or a robot arm can clean the inside of the treatment tank 15. Since the treatment tank 15 can be unloaded to the unloading position 84, the treatment tank 15 is easy to clean. Therefore, the type and particle size of the abrasive powder 2 can be easily changed. Moreover, the processing tank 15 can be carried out together with the outer frame 26. Therefore, the processing tank 15 can be easily replaced with a new one while the processing liquid 1 and the polishing powder 2 remain inside.

[0038] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the present invention, and all technical matters included in the technical ideas described in the claims are subject to the present invention. The above-described embodiments are preferred examples, but a person skilled in the art can realize various alternatives, modifications, variations, or improvements from the contents disclosed in this specification, and these are included in the technical scope described in the appended claims.
