Description

Technical Field

[0001] The utility model relates to the technical field of impeller maintenance of shot blasting machines, specifically to a maintenance mechanism for shot blasting machines. Background Technique

[0002] A shot blasting machine uses a high-speed rotating impeller to throw shot at continuously rotating workpieces in a drum, so as to achieve the purpose of cleaning the workpieces. It is applicable to the sand cleaning, rust removal, scale removal and surface strengthening of medium and small-sized castings and forgings in various industries;

[0003] However, in the existing shot blasting machines, the blades of the impeller of the shot head are in direct contact and impact with the abrasive, applying force to the abrasive, causing the abrasive to impact the upper end of the material. Due to the frequent contact between the blades and the abrasive, the blades will be severely worn. At this time, the staff needs to replace the worn blades. When replacing the blades, in order to ensure the dynamic balance of the impeller during rotation, the staff needs to replace the corresponding blades together to avoid vibration during high-speed rotation of the impeller. Therefore, the staff needs to disassemble two blades. Since the blades in the shot impeller on the market are usually fixed and installed by bolts, the staff needs to disassemble at least two screws to complete the replacement of the blades, resulting in low maintenance efficiency; Therefore, it does not meet the existing needs, and for this reason, we propose a maintenance mechanism for shot blasting machines.

[0024] Limit stress rods 2, which are arranged in a circular array inside the shot head impeller bracket 1. The shot head impeller bracket 1 is welded to the limit stress rods 2. Installing the limit stress rods 2 can limit the blade body 3 and at the same time bear the centrifugal force of the blade body 3 during rotation, making the blade body 3 more stable in installation, preventing the blade body 3 from shaking, enhancing the use effect of the device. The blade body 3 is arranged outside the limit stress rods 2. The blade body 3 is connected to the limit stress rods 2 through a card slot. A limit installation hole 4 is arranged at the upper end of the blade body 3;

[0025] Installation fitting holes 5, which are arranged in a circular array at the upper end of the shot head impeller bracket 1. A lifting clamping shaft 6 is installed inside the installation fitting holes 5. Installing the lifting clamping shaft 6 enables it to be stuck inside the limit installation hole 4 under the block of the unlocking rotating disc 8, thereby preventing the blade body 3 from moving, limiting the blade body 3, and making the installation of the blade body 3 more convenient. The lifting clamping shaft 6 is connected to the shot head impeller bracket 1 through a card slot for up and down sliding connection. A pulling spring 7 is arranged outside the lifting clamping shaft 6. Installing the pulling spring 7 can make the unlocking rotating disc 8 pull up the lifting clamping shaft 6 when the limit on the lifting clamping shaft 6 is released, separating the lifting clamping shaft 6 from the limit installation hole 4, facilitating the staff to laterally move the blade body 3, and then take out the worn blade body 3, making the device overhaul more convenient and enhancing the use effect of the device. An unlocking rotating disc 8 is installed at the upper end of the shot head impeller bracket 1. A positioning and disassembly rotating disc 10 is arranged at the upper end of the unlocking rotating disc 8. Six unlocking holes 9 are annularly arranged at the upper end of the unlocking rotating disc 8. Installing the unlocking rotating disc 8 can simultaneously unlock the six lifting clamping shafts 6 inside the device, facilitating the staff to disassemble the blade body 3. Two positioning and disassembly holes 11 are arranged at the upper end of the positioning and disassembly rotating disc 10. Installing the positioning and disassembly rotating disc 10 to cooperate with the unlocking rotating disc 8 can facilitate the staff to position and disassemble the blade body 3. Without screwing the screws, the corresponding blade body 3 can be quickly disassembled, greatly improving the overhaul efficiency of the device. Sliding dampers are arranged between the positioning and disassembly rotating disc 10 and the unlocking rotating disc 8 and the shot head impeller bracket 1.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a fixed collar 13 is installed at the upper end of the throwing head impeller support 1. The fixed collar 13 is fixedly connected to the throwing head impeller support 1. An upper top spring 14 is installed inside the fixed collar 13. The upper top spring 14 is fixedly connected to the fixed collar 13. A downward pressure support 12 is installed at the upper end of the upper top spring 14. By installing the downward pressure support 12, it can cooperate with the downward pressure shaft 15 to push the lifting clamping shaft 6 downward, so that the lifting clamping shaft 6 is pressed into the limit installation hole 4, which is convenient for the staff to rotate and align to disassemble the rotating disk 10 and unlock the rotating disk 8, and further limit the lifting clamping shaft 6, making the device maintenance simpler. The downward pressure support 12 is fixedly connected to the upper top spring 14. A downward pressure shaft 15 is installed at the lower end of the downward pressure support 12. The downward pressure shaft 15 is fixedly connected to the downward pressure support 12. The downward pressure support 12 is connected to the fixed collar 13 through a card slot for up and down sliding connection. The lower end of the upward pulling spring 7 is welded to the lifting clamping shaft 6. The upper end of the upward pulling spring 7 is fixedly connected to the throwing head impeller support 1. The alignment and disassembly rotating disk 10 is rotatably connected to the throwing head impeller support 1. The unlocking rotating disk 8 is rotatably connected to the throwing head impeller support 1.

[0027] Working principle: When in use, when the staff needs to replace the blades of the shot blasting machine, they only need to rotate the alignment and disassembly rotating disk 10 to move the alignment and disassembly hole 11 above the blade body 3 to be disassembled. Then, the staff rotates the unlocking rotating disk 8 to release the limit on the lifting clamping shaft 6, so that the upper pulling spring 7 pulls the lifting clamping shaft 6 upward, and the lower end of the lifting clamping shaft 6 is pulled out from the inside of the limit mounting hole 4. Then, the staff moves the blade body 3 horizontally to release the cooperation between the blade body 3 and the limit stress rod 2, and the aligned blade body 3 can be disassembled. In this device, the installation of the limit stress rod 2 can limit the blade body 3 and at the same time bear the centrifugal force of the blade body 3 during rotation, making the installation of the blade body 3 more stable, preventing the blade body 3 from shaking, and enhancing the use effect of the device. The installation of the lifting clamping shaft 6 enables it to be stuck inside the limit mounting hole 4 under the block of the unlocking rotating disk 8, thereby preventing the blade body 3 from moving, limiting the blade body 3, and making the installation of the blade body 3 more convenient. The installation of the upper pulling spring 7 enables the unlocking rotating disk 8 to pull the lifting clamping shaft 6 upward when releasing the limit on the lifting clamping shaft 6, separating the lifting clamping shaft 6 from the limit mounting hole 4, facilitating the staff to move the blade body 3 horizontally, and then taking out the worn blade body 3, making the device maintenance more convenient and enhancing the use effect of the device. The installation of the unlocking rotating disk 8 can unlock the six lifting clamping shafts 6 inside the device at the same time, facilitating the staff to disassemble the blade body 3. The installation of the alignment and disassembly rotating disk 10 in cooperation with the unlocking rotating disk 8 can facilitate the staff to align and disassemble the blade body 3. Without screwing the screws, the aligned blade body 3 can be quickly disassembled, greatly improving the maintenance efficiency of the device. The installation of the lower pressing bracket 12 in cooperation with the lower pressing shaft 15 can push the lifting clamping shaft 6 downward, pressing the lifting clamping shaft 6 into the limit mounting hole 4, thereby facilitating the staff to rotate the alignment and disassembly rotating disk 10 and the unlocking rotating disk 8, and then limiting the lifting clamping shaft 6, making the device maintenance simpler.
