Technical Field

[0001] The utility model relates to the technical field of pretreatment, in particular to a pretreatment device for shot peening particles. Background Art

[0002] A shot peening machine is a device that impacts the surface of metal with a high-speed stream of shot peening particles. After the metal is processed by the shot peening machine, its reliability and durability are improved. Since the shot peening effects produced by shot peening particles of different sizes are different, the shot peening particles ejected by the shot peening machine need to be pretreated according to the material of the metal.

[0003] The shot peening particles of the shot peening machine are pretreated by using a vibrating screen machine. The vibrating screen machine screens the shot peening particles by vibrating a filter screen, and selects the shot peening particles of the corresponding size according to the material of the workpiece to be processed. However, when this vibrating screen machine is used, since the sizes of the shot peening particles required each time are different, filter screens with different filter holes need to be arranged to replace the filter screen for screening the corresponding shot peening particles, and the replacement and disassembly of the filter screen reduce the pretreatment efficiency.

[0028] Embodiment 1

[0029] This embodiment provides a pre-treatment device for shot peening particles, as Figure 1As shown in the figure, it includes a base 1. At the top corners of the base 1, vibration springs 2 are fixedly installed. At the top of the vibration springs 2, a vibrating sieve support plate 3 is fixedly installed. At the side of the vibrating sieve support plate 3, a polarization block 4 is rotatably connected. A motor fixedly connected to the polarization block 4 is fixedly installed at the side of the vibrating sieve support plate 3. The polarization block 4 is driven by the motor to rotate, so that the vibrating sieve support plate 3 vibrates.

[0030] As Figure 3 and Figure 4 shown in the figure, a vibrating sieve assembly 5 is arranged at the center of the vibrating sieve support plate 3. The vibrating sieve assembly 5 includes a first filter screen 51, a second filter screen 52, sliders 54 and an adjusting part. The side of the first filter screen 51 is fixedly connected to the vibrating sieve support plate 3. Shot peening particles flow on the top of the first filter screen 51. When the vibrating sieve support plate 3 vibrates, it drives the first filter screen 51 to vibrate. The first filter screen 51 screens the shot peening particles through the sieve holes on it.

[0031] As Figure 2 and Figure 4 shown in the figure, the shape of the first filter screen 51 is the same as that of the second filter screen 52. Sliders 54 are fixedly installed at the top of the second filter screen 52. A chute 53 is opened at the bottom of the first filter screen 51. The sliders 54 slide left and right in the chute 53 at the bottom of the first filter screen 51. The chute 53 limits the sliders 54 to prevent the sliders 54 from rotating in the chute 53.

[0032] A plurality of sliders 54 are provided and are evenly installed at the four corners of the second filter screen 52. The plurality of sliders 54 are parallel to each other. The sliders 54 slide left and right at the bottom of the first filter screen 51, so as to improve the stability of the left and right sliding of the second filter screen 52.

[0033] By sliding the second filter screen 52 to change its relative position with the first filter screen 51, the sieve holes of the first filter screen 51 and the second filter screen 52 are misaligned. The overlapping part of the sieve holes of the first filter screen 51 and the second filter screen 52 is the hole for screening the shot peening particles. By misaligning the first filter screen 51 and the second filter screen 52, the sieve hole size is adjusted to screen shot peening particles of different sizes.

[0034] As Figure 4 shown in the figure, an adjusting part is arranged on the inner wall of the slider 54. The adjusting part includes a lead screw 55 and a turntable 56. The rod body of the lead screw 55 is threadedly connected to the slider 54. A turntable 56 is fixedly installed at the end of the lead screw 55. Friction lines are opened on the arc surface of the turntable 56. The friction of the turntable 56 is increased through the friction lines, so as to rotate the turntable 56. Rotating the turntable 56 makes the lead screw 55 rotate, thereby adjusting the position of the lead screw 55, that is, adjusting the relative position of the first filter screen 51 and the second filter screen 52.

[0035] In this embodiment, the slider 54 is slid left and right in the chute 53 by rotating the lead screw 55, so as to adjust the relative positions of the first filter screen 51 and the second filter screen 52, make the sieve holes of the first filter screen 51 misaligned with those of the second filter screen 52, and adjust the sieve hole size, thereby screening shot particles of different sizes, and avoiding reducing the efficiency by replacing the sieve mesh with a corresponding aperture when screening different shot particles.

[0036] Embodiment 2

[0037] Based on Embodiment 1, this embodiment proposes a pretreatment device for shot particles, as Figure 4 shown, a positioning component 6 is arranged on the side of the first filter screen 51. The positioning component 6 includes a guide rod 62, a snap ring 63 and a clamping plate 64. The guide rod 62 penetrates through the turntable 56, the end of the guide rod 62 is fixedly installed with the snap ring 63, the clamping plate 64 is fixedly installed on the side of the first filter screen 51 close to the turntable 56, and the snap ring 63 is clamped with the clamping plate 64.

[0038] By clamping the snap ring 63 with the clamping plate 64, the snap ring 63 uses the guide rod 62 to restrict the rotation of the turntable 56 and the lead screw 55, and avoids the movement of the slider 54 caused by the synchronous vibration of the lead screw 55 during the vibration of the first filter screen 51. Two symmetrically arranged guide rods 62 are fixedly installed on the side of one snap ring 63, and the two guide rods 62 prevent the guide rod 62 from rotating on the snap ring 63. The end of the guide rod 62 is fixedly installed with a limit disc 61. The limit disc 61 limits the guide rod 62 to prevent it from falling off the turntable 56.

[0039] A plurality of clamping plates 64 are provided and are distributed at equal angles in a ring shape on the side of the first filter screen 51 to improve the clamping stability between the clamping plate 64 and the snap ring 63.

[0040] As Figure 4 shown, a magnet 65 is fixedly installed inside the first filter screen 51. The snap ring 63 is made of one of iron sheet, cobalt sheet or nickel sheet. The side of the magnet 65 is fixedly connected to the clamping plate 64 through magnetic stainless steel. The magnet 65 and the snap ring 63 are separated by magnetic stainless steel to avoid direct contact between the snap ring 63 and the magnet 65, resulting in damage to the magnet 65.

[0041] In this embodiment, after adjusting the relative positions of the first filter screen 51 and the second filter screen 52, the snap ring 63 is moved towards the clamping plate 64 by pushing the limit disc 61 and the guide rod 62. The clamping plate 64 clamps the snap ring 63 to make it unable to rotate, that is, the lead screw 55 cannot rotate. At the same time, the magnetic force of the magnet 65 is used to attract the snap ring 63, so that the snap ring 63 is always clamped with the clamping plate 64. The rotation of the snap ring 63 is restricted by the clamping plate 64, thereby avoiding the rotation of the lead screw 55 from changing the position of the slider 54, resulting in a change in the relative positions of the first filter screen 51 and the second filter screen 52 during the vibration screening process.

[0042] The above specific embodiments are only several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
