[0002] Cantilever shot blasting machine is a kind of equipment that uses high-speed rotating shot blasting machine to accelerate the projectile to the surface of the workpiece to remove surface oxides, impurities and improve surface quality. The shot blasting machine can simultaneously perform sand removal, core removal and cleaning of castings. It usually consists of a shot blasting chamber, a shot blasting machine, a conveying system, a cleaning system, a control system, etc. The shot blasting machine is installed on one side of the shot blasting chamber to perform one-way processing on the workpiece.
[0003] In the prior art, a cantilever shot blasting machine hangs a plurality of workpieces by a hook, and uses a shot blaster to rotate and throw the projectiles at a high speed, so that the projectiles process a plurality of workpieces at the same time, thereby improving the cleaning efficiency.
[0004] However, when this cantilever shot blasting machine is used to clean multiple workpieces, the workpieces at adjacent positions overlap and block each other, and the workpieces are not within the range of shot blasting, so the workpieces are not completely cleaned. Utility Model Content
[0005] The utility model aims to solve the problem in the background technology that workpieces at adjacent positions overlap and block and affect shot blasting, and proposes a cantilever shot blasting machine for single-side processing.
[0006] The technical solution of the utility model: a cantilever shot blasting machine for single-side processing, comprising:
[0007] A shot blasting bin, wherein a shot blasting device is fixedly installed on the side of the shot blasting bin, a bin door is opened on the front of the shot blasting bin, a guide rail is fixedly installed on the top of the shot blasting bin, and a rail car is slidably connected to the bottom of the guide rail;
[0008] The suspension assembly comprises an electric push rod, an extension assembly, a first slider, a push assembly, and a hook. The extension assembly is fixedly installed at the arc surface of the electric push rod and near the bottom end. A folding frame is fixedly installed at the bottom of the extension assembly and at one end near the electric push rod. The first slider is fixedly installed at the upper cross position of the folding frame. The push assembly is arranged at one end of the folding frame away from the electric push rod. A hook is fixedly installed at the bottom of the first slider.
[0009] The top of the electric push rod is fixedly connected to the rail car.
[0010] Optionally, a clearance gap is opened on the top of the shot blasting bin, and the electric push rod enters the interior of the shot blasting bin through the clearance gap.
[0011] Optionally, a plurality of the extension components are provided and are evenly distributed at equal angles along the electric push rod, and a fixed ring is fixedly installed on the tops of the plurality of extension components.
[0012] Optionally, the pushing component includes a linkage rod, a second slider and a collar. The collar slides up and down on the arc surface of the electric push rod. The bottom of the collar is rotatably connected to the linkage rod. The end of the linkage rod is hinged to the second slider. The side of the second slider is fixedly connected to the end of the folding frame. The collar is located inside the shot blasting chamber.
[0013] Optionally, the extension component includes a support guide plate, an extension slide rod, a chute and a linking plate. The bottom of the support guide plate is slidably connected to the extension slide rod. The end of the extension slide rod is fixedly installed with the linking plate.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects:
[0018] In the utility model, when the electric push rod contracts, the collar abuts against the top wall of the shot blasting chamber. The collar moves downward relative to the electric push rod. The collar uses the slider to pull the end of the folding frame, so that the plurality of sliders at the bottom of the folding frame are dispersed, and thus the workpieces suspended on the hooks can be dispersed, avoiding overlap and occlusion between the workpieces and affecting the shot blasting treatment.
[0019] Furthermore, the lengths of the plurality of hooks on the same folding frame are different, so that the workpieces suspended by the plurality of hooks are at different heights, reducing the overlap and occlusion between the workpieces.
[0020] Furthermore, when the slider drives the folding frame to unfold, the slider drives the linking plate to move, so that the extension slide rod is pulled out from the bottom of the support guide plate, further expanding the dispersion distance of the workpieces suspended on the hooks. And during the process of the rail vehicle driving the suspension assembly to move, the extension slide rod is retracted into the support guide plate, reducing the overall volume of the suspension assembly, and avoiding collision during the process of the rail vehicle driving the suspension assembly to move.

[0031] Embodiment 1
[0032] This embodiment provides a cantilever shot blasting machine for single-sided processing, as Figure 1 shown, which includes a shot blasting chamber 1, a shot blaster 2 fixedly installed on the side of the shot blasting chamber 1, a chamber door 3 opened on the front of the shot blasting chamber 1, a guide rail 4 fixedly installed on the top of the shot blasting chamber 1, a rail car 5 slidably connected to the bottom of the guide rail 4, and a suspension assembly 6 provided at the bottom of the rail car 5. Open the chamber door 3 and send the suspension assembly 6 into the shot blasting chamber 1 through the rail car 5.
[0033] As Figure 2 and 3 shown, the suspension assembly 6 includes an electric push rod 61, an expansion assembly 62, a first slider 63, a pushing assembly, and a hook 67. The top of the electric push rod 61 is fixedly connected to the rail car 5. A relief slot is opened on the top of the shot blasting chamber 1, and the electric push rod 61 enters the interior of the shot blasting chamber 1 from the relief slot. The expansion assembly 62 is fixedly installed on the arc surface of the electric push rod 61 and near the bottom end. A folding frame 64 is fixedly installed at the bottom of the expansion assembly 62 and near one end of the electric push rod 61. A torsion spring is elastically connected to the intersection position of the folding frame 64. Initially, the folding frame 64 is in a folded state.
[0034] As Figure 4 shown, the first sliders 63 are fixedly installed at the upper intersection positions of the folding frame 64, and a hook 67 is fixedly installed at the bottom of the first slider 63. The folding of the folding frame 64 gathers the first sliders 63 together. By unfolding the folding frame 64, the first sliders 63 are dispersed, and thus the workpieces suspended on the hooks 67 can be dispersed, reducing the occlusion and overlap between the workpieces and avoiding blocking the shot from contacting the workpieces.
[0035] As Figure 2 shown, multiple hooks 67 are provided on one folding frame 64, and the lengths of each hook 67 are different. Along the direction from the end of the folding frame 64 near the electric push rod 61 to the end of the folding frame 64 far from the electric push rod 61, the lengths of the hooks 67 on the folding frame 64 gradually decrease. The different lengths of the multiple hooks 67 on the same folding frame 64 enable the workpieces suspended on the multiple hooks 67 to be at different heights, providing longitudinal relief and reducing the occlusion between the workpieces.
[0036] As shown Figure 2 As shown, at one end of the folding rack 64 away from the electric push rod 61, a pushing component is arranged. The pushing component includes a linkage rod 65, a second slider 66 and a collar 68. The collar 68 slides up and down on the arc surface of the electric push rod 61. The bottom of the collar 68 is rotatably connected to the linkage rod 65. The end of the linkage rod 65 is hinged to the second slider 66. The side of the second slider 66 is fixedly connected to the end of the folding rack 64. The collar 68 is located inside the shot blasting chamber 1.
[0037] When the electric push rod 61 contracts, the collar 68 abuts against the top wall of the shot blasting chamber 1. The collar 68 moves downward relative to the electric push rod 61. The collar 68 uses the second slider 66 to pull the end of the folding rack 64, so that the multiple first sliders 63 at the bottom of the folding rack 64 are dispersed, and the workpieces suspended on the hook 67 can be dispersed.
[0038] A plurality of expansion components 62 are provided and are annularly and equiangularly distributed along the electric push rod 61. A fixed ring is fixedly installed at the top of the plurality of expansion components 62. The fixed ring makes the plurality of expansion components 62 at the same height and avoids the bending of the expansion components 62. The design of the plurality of expansion components 62 increases the number of suspended workpieces and improves the processing efficiency.
[0039] In this embodiment, when the electric push rod 61 contracts, the collar 68 abuts against the top wall of the shot blasting chamber 1. The collar 68 moves downward relative to the electric push rod 61. The collar 68 uses the second slider 66 to pull the end of the folding rack 64, so that the multiple first sliders 63 at the bottom of the folding rack 64 are dispersed, and the workpieces suspended on the hook 67 can be dispersed. Moreover, the lengths of the multiple hooks 67 on the same folding rack 64 are different, so that the workpieces suspended by the multiple hooks 67 are at different heights, expanding the distance between the workpieces and avoiding the overlap and occlusion between the workpieces from affecting the shot blasting treatment.
[0040] Embodiment 2
[0041] Based on Embodiment 1, this embodiment proposes a cantilever shot blasting machine for single-sided treatment, as shown Figure 3 and 4 As shown, the expansion component 62 includes a support guide plate 621, an expansion slide rod 622, a chute 623 and a linkage plate 624. The bottom of the support guide plate 621 is slidably connected to the expansion slide rod 622. The end of the expansion slide rod 622 is fixedly installed with the linkage plate 624. A chute 623 is opened at the bottom of the expansion slide rod 622. The first slider 63 slides in the chute 623 at the bottom of the expansion slide rod 622. The expansion slide rod 622 plays a role in guiding and supporting the first slider 63.
[0042] A folding rack 64 is fixedly installed at the bottom of the support guide plate 621 and near the end of the support guide plate 621. The side of the linkage plate 624 is fixedly connected to the second slider 66.
[0043] As shownFigure 4 As shown, the collar 68 moves downward relative to the electric push rod 61 and uses the linkage rod 65 to push the second slider 66. The second slider 66 unfolds the folding frame 64 and drives the linkage plate 624. The movement of the linkage plate 624 pushes out the extension slide rod 622, extending the overall length of the extension support guide plate 621 and the extension slide rod 622. Moreover, the first slider 63 slides in the chute 623 at the bottom of the extension slide rod 622. While pushing out the extension slide rod 622, the first slider 63 slides at the bottom of the chute 623.
[0044] The extension slide rod 622 is pushed out from the bottom of the support guide plate 621, increasing the dispersion distance between the first slider 63 and the hook 67. During the movement of the rail vehicle 5, the folding frame 64 is in a folded state, and the extension slide rod 622 is retracted into the support guide plate 621, reducing the overall volume of the suspension assembly 6, thus preventing collisions during the movement of the rail vehicle 5 driving the suspension assembly 6.
[0045] In this embodiment, while the second slider 66 drives the folding frame 64 to unfold, the second slider 66 drives the linkage plate 624 to move, so that the extension slide rod 622 is pulled out from the bottom of the support guide plate 621, further increasing the dispersion distance of the workpieces suspended on the hook 67. Moreover, during the movement of the rail vehicle 5 driving the suspension assembly 6, the extension slide rod 622 is retracted into the support guide plate 621, reducing the overall volume of the suspension assembly 6, thus preventing collisions during the contraction of the suspension assembly 6 when the rail vehicle 5 drives the suspension assembly 6.
[0046] The above specific embodiments are merely 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.
