Description

Technical Field

[0001] This application relates to the field of shot blasting technology, and in particular to an anti-splash structure for a shot blasting machine. Background Technology

[0002] Shot blasting is a processing equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. It's a treatment technique that uses a shot blaster to propel steel shot at high speed onto the surface of a material. Shot blasting can remove surface contaminants from a partially coated surface and create a surface profile that increases coating adhesion, thus strengthening the workpiece. Unlike shot peening, shot blasting is used to reduce fatigue life, increase surface stress, enhance component strength, or prevent fretting.

[0003] Existing shot blasting machines are prone to splashing rust-removing iron filings and shot particles during shot blasting of workpieces, posing a safety hazard, and therefore require further improvement. Utility Model Content

[0004] To improve the safety of shot blasting machines, this application provides an anti-splash structure for shot blasting machines.

[0005] The anti-splash structure for a shot blasting machine provided in this application adopts the following technical solution:

[0006] An anti-splash structure for a shot blasting machine includes a shot blasting machine body and a shot blasting box connected to the output end of the shot blasting machine body. A mounting plate is fixedly attached to the outer wall of the output end of the shot blasting machine body. A shot blasting port communicating with the output port of the shot blasting machine body is opened on one side of the shot blasting box, and an inlet / outlet port for workpieces to enter and exit is opened on the other side of the shot blasting box. A pair of clamping bars located on both sides of the shot blasting port are slidably connected to the side wall of the shot blasting box. A slot for the mounting plate to slide and insert is opened on the side wall of the two clamping bars that are close to each other. The shot blasting box is provided with a first driving component for driving the clamping bars to slide.

[0007] By adopting the above technical solution, after the output end of the shot blasting machine body and the shot blasting box are aligned, the two clamping bars are driven by the first drive component to slide towards each other, so that the mounting plate is embedded in the slot of the clamping bar, thereby fixing the shot blasting box and the shot blasting machine body. The workpiece to be processed is placed in the shot blasting box through the inlet and outlet for shot blasting, reducing the possibility of iron filings and shot granules splashing and improving the safety of shot blasting machine. In addition, this structure can also adapt to the output end of shot blasting machine body of different sizes, improving the versatility and flexibility of the overall device.

[0008] Preferably, the outer wall of the shot blasting box is provided with a sliding groove, and a slider that is slidably connected to the sliding groove is fixedly connected to the clamping strip.

[0009] By adopting the above technical solution, the clamping bar is slidably connected to the slide groove on the outer wall of the shot blasting box through the slider, so that the clamping bar can slide stably on the shot blasting box, thereby realizing the clamping or loosening operation of the output end of the shot blasting machine body.

[0010] Preferably, the first driving assembly includes a first lead screw rotatably connected to the outer wall of the shot blasting chamber. The first lead screw has a first threaded section and a second threaded section, with the threads of the first threaded section and the second threaded section having opposite directions. The sliders of the two clamping bars are respectively threaded onto the first threaded section and the second threaded section.

[0011] By adopting the above technical solution, the first thread section and the second thread section of the first lead screw have opposite thread directions, which enables the two clamping bars to move towards or away from each other when the first lead screw rotates.

[0012] Preferably, the first drive assembly further includes a knob fixedly connected to the end of the first lead screw.

[0013] By adopting the above technical solution, the first lead screw can be driven to rotate by a manual knob, thus improving the ease of operation.

[0014] Preferably, the output end of the shot blasting machine body is inserted into the shot blasting port, and the shot blasting box is provided with a sealing ring that is fixedly connected to the inner wall of the shot blasting port and abuts against the outer peripheral wall of the output end of the shot blasting machine body.

[0015] By adopting the above technical solution, the sealing ring can effectively fill the gap between the output end of the shot blasting machine body and the shot blasting port, preventing shot and iron filings from splashing out of the shot blasting box.

[0016] Preferably, a support plate is fixedly connected to the bottom of the shot blasting box on the side away from the shot blasting machine body. A sliding seat is slidably connected to the support plate along the axial direction of the inlet and outlet. The sliding seat is provided with a crossbar that slides through the inlet and outlet. A tooling plate is fixedly connected to the crossbar. The workpiece is installed on the tooling plate. The shot blasting box is provided with a second drive assembly for driving the sliding seat to slide.

[0017] By adopting the above technical solution, the workpiece is pre-installed on the tooling plate, and the sliding seat is driven to slide along the support plate by the second drive component, thereby moving the crossbar and the tooling plate from the inlet and outlet into or out of the shot blasting box, realizing the automatic loading and unloading function of the workpiece. At the same time, the distance between the workpiece and the output end of the shot blasting machine body can be adjusted to meet different processing needs.

[0018] Preferably, the second drive assembly includes a second lead screw rotatably connected to the support plate, the second lead screw being threaded through the sliding seat.

[0019] By adopting the above technical solution, the sliding seat is driven to slide by a lead screw, ensuring the smoothness of the transmission process and the positioning accuracy.

[0020] Preferably, the second drive assembly further includes a loading / unloading motor for driving the second lead screw to rotate.

[0021] By adopting the above technical solution, an additional loading and unloading motor is added to drive the second lead screw to rotate, which further simplifies the operation process, reduces manual intervention, improves the automation level of the equipment, and reduces labor intensity.

[0022] Preferably, the crossbar is rotatably connected to the sliding seat about its own axis, and the sliding seat is equipped with a rotary motor that drives the crossbar to rotate.

[0023] By adopting the above technical solution, the crossbar can rotate around its own axis, thereby driving the workpiece on the tooling plate to rotate, so that the workpiece can be impacted by the shot in all directions and evenly during the shot blasting process, which effectively improves the rust removal effect and surface treatment quality.

[0024] Preferably, the shot blasting box is slidably connected to a sealing plate. There are two sealing plates that are symmetrical along the axis of the crossbar. Each of the two sealing plates has a clearance groove on the side that is close to each other, allowing the crossbar to pass through. The shot blasting box is equipped with a cylinder that drives the sealing plates to slide.

[0025] By adopting the above technical solution, the sealing plate is driven by the cylinder to slide to a suitable position, effectively sealing the inlet and outlet, preventing rust-removing iron filings and shot from splashing out of the inlet and outlet, thereby improving the safety of shot blasting machine operation.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. After the output end of the shot blasting machine body and the shot blasting box are aligned, the two clamping bars are driven by the first drive component to slide towards each other, so that the mounting plate is embedded in the slot of the clamping bar, thereby fixing the shot blasting box and the shot blasting machine body. The workpiece to be processed is placed in the shot blasting box through the inlet and outlet for shot blasting, reducing the possibility of iron filings and shot granules splashing and improving the safety of shot blasting machine. In addition, this structure can also adapt to the output end of the shot blasting machine body of different sizes, improving the versatility and flexibility of the overall device.

[0028] 2. The workpiece is pre-installed on the tooling tray. The sliding seat is driven to slide along the support plate by the second drive component, thereby moving the crossbar and the tooling tray from the inlet and outlet into or out of the shot blasting box, realizing the automatic loading and unloading function of the workpiece. At the same time, the distance between the workpiece and the output end of the shot blasting machine body can be adjusted to meet different processing requirements.

[0029] 3. The crossbar can rotate around its own axis, thereby driving the workpiece on the tooling plate to rotate, so that the workpiece can be impacted by the shot in all directions and evenly during the shot blasting process, which effectively improves the rust removal effect and surface treatment quality.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses an anti-splash structure for a shot blasting machine, referring to... Figure 1 , Figure 2 The system includes a shot blasting machine body 1 and a shot blasting box 2 connected to the output end of the shot blasting machine body 1. A shot blasting port 21 is provided on one side of the shot blasting box 2 for the output end of the shot blasting machine body 1 to be inserted, so that the inner cavity of the output end of the shot blasting machine body 1 is connected to the inner cavity of the shot blasting box 2. The shot blasting box 2 is provided with a sealing ring 211 fixedly connected to the inner wall of the shot blasting port 21 and abutting against the outer peripheral wall of the output end of the shot blasting machine body 1.

[0038] Reference Figure 2 , Figure 3 A mounting plate 11 is fixedly protruding from the outer wall of the output end of the shot blasting machine body 1. A pair of clamping strips 3, located on the left and right sides of the shot blasting port 21 respectively, are slidably connected to the side wall of the shot blasting box 2 near the shot blasting machine body 1. The side walls of the two clamping strips 3 that are close to each other have slots 31 for the mounting plate 11 to slide into. The outer wall of the shot blasting box 2 has a sliding groove 22. There are two sliding grooves 22, located above and below the shot blasting port 21 respectively. The clamping strips 3 are fixedly connected to sliders 32 that are slidably connected to the sliding grooves 22.

[0039] The outer wall of the shot blasting box 2 is fixedly connected to a fixing block 23 located outside the slide groove 22. There are two fixing blocks 23. The fixing blocks 23 are equipped with a first driving component 4 that drives the two clamping bars 3 to slide synchronously toward each other or away from each other. The first driving component 4 includes a first lead screw 41 rotatably connected to the outer wall of the shot blasting box 2 and a knob 42 fixedly connected to the end of the first lead screw 41. The axial direction of the first lead screw 41 is parallel to the length direction of the slide groove 22. The first lead screw 41 has a first threaded section and a second threaded section. The thread directions of the first threaded section and the second threaded section are opposite. The sliders 32 of the two clamping bars 3 are respectively threadedly sleeved on the first threaded section and the second threaded section.

[0040] Reference Figure 4 , Figure 5 The shot blasting box 2 has an inlet / outlet 24 on its side wall away from the shot blasting machine body 1. A support plate 25 located below the inlet / outlet 24 is fixedly connected to the bottom of the outer side wall of the shot blasting box 2. A sliding seat 5 is slidably connected to the support plate 25 along the axial direction of the inlet / outlet 24. A fixing plate 251 is fixedly connected to the upper end face of the side of the support plate 25 away from the shot blasting box 2. A guide rod 252 passing through the sliding seat 5 is fixedly connected between the fixing plate 251 and the outer wall of the shot blasting box 2. The shot blasting box 2 is provided with a second drive assembly 6 for driving the sliding seat 5 to slide. The second drive assembly 6 includes a second lead screw 61 rotatably connected to the fixing plate 251 and the side wall of the shot blasting box 2, and a loading / unloading motor 62 fixedly connected to the outer wall of the fixing plate 251. The second lead screw 61 is threaded through the sliding seat 5, and the output shaft of the loading / unloading motor 62 is coaxially fixedly connected to the second lead screw 61.

[0041] A sliding seat 5 is rotatably connected to a crossbar 51 that slides through the inlet / outlet 24. The sliding seat 5 is equipped with a rotary motor 53 that drives the crossbar 51 to rotate. The rotary motor 53 is fixedly connected to the outer wall of the sliding seat 5. The output shaft of the rotary motor 53 is coaxially fixedly connected to the end of the crossbar 51. A tooling disc 52 is fixedly connected to the end of the crossbar 51 away from the sliding seat 5. The workpiece is mounted on the tooling disc 52. In this embodiment, the tooling disc 52 is a pneumatic chuck. In other embodiments, the tooling disc 52 is a powerful magnetic block, and the workpiece is fixed to the tooling disc 52 by magnetic attraction.

[0042] A sealing plate 26, controlling the opening and closing of the inlet and outlet ports 24, is slidably connected to the side wall of the shot blasting box 2 away from the shot blasting machine body 1. Two sealing plates 26 are provided and symmetrically arranged along the axis of the crossbar 51. The two sealing plates 26 are respectively slidably connected to the front and rear side walls of the shot blasting box 2. Each of the two sealing plates 26 has a clearance groove on the side closest to each other, allowing the crossbar 51 to pass through. After the sealing plate 26 is slidably closed, the outer peripheral wall of the crossbar 51 abuts against the inner wall of the clearance groove. The shot blasting box 2 is equipped with a cylinder 27 that drives the sealing plate 26 to slide. The cylinder body of the cylinder 27 is fixedly connected to the outer wall of the shot blasting box 2, and the piston rod of the cylinder 27 is fixedly connected to the sealing plate 26. The bottom of the shot blasting box 2 is conical, and a discharge pipe 28 is fixedly inserted through the bottom wall of the shot blasting box 2.

[0043] The implementation principle of the anti-splash structure of a shot blasting machine according to an embodiment of this application is as follows: After the output end of the shot blasting machine body 1 is inserted into the shot blasting port 21, the mounting plate 11 and the slot 31 of the clamping strip 3 are aligned. Rotating the knob 42 drives the first lead screw 41 to rotate, thereby driving the two clamping strips 3 to slide towards each other, so that the mounting plate 11 is embedded in the slot 31 of the clamping strip 3, thereby fixing the shot blasting box 2 and the shot blasting machine body 1.

[0044] After the workpiece to be processed is installed on the tooling tray 52, the loading and unloading motor 62 drives the second lead screw 61 to rotate, thereby driving the sliding seat 5 to slide towards the shot blasting box 2. This causes the crossbar 51 and the tooling tray 52 to move from the inlet / outlet 24 into the shot blasting box 2. The piston rod of the cylinder 27 drives the sealing plate 26 to slide towards the crossbar 51 to close the inlet / outlet 24. The shot blasting machine body 1 is started to perform shot blasting on the workpiece. During the shot blasting process, the rotary motor 53 drives the crossbar 51 to rotate around its own axis, thereby causing the workpiece on the tooling tray 52 to rotate. This allows the workpiece to be impacted by the shot in all directions and evenly during the shot blasting process, effectively improving the rust removal effect and surface treatment quality. Iron filings and shot are discharged from the shot blasting box 2 through the discharge pipe 28.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
