Description

Technical Field

[0001] This application relates to the technical field of grinding and sweeping machines, and in particular to an environmentally friendly integrated suspended grinding and sweeping machine. Background Technology

[0002] The suspended cleaning machine, also known as the hook-type cleaning machine, uses a hanging system to transport the workpiece into the cleaning chamber and then uses a cleaning device to propel the cleaning material at high speed onto the workpiece surface to remove impurities, welding slag, or rust. It is widely used for surface cleaning and strengthening of parts such as aluminum-magnesium alloys and aerospace components.

[0003] Currently, there is a suspended grinding and cleaning machine, including a grinding and cleaning cabinet. A gantry frame, a hook, and a drive assembly are mounted on the cabinet. The hook is positioned on the gantry frame, and the drive assembly moves the hook. A grinding device is installed inside the cabinet. When grinding and cleaning of a workpiece is required, the cabinet automatically opens, suspending the workpiece on the hook. Then, the drive assembly is activated, and the hook suspends the corresponding workpiece and moves it into the cabinet. The cabinet automatically closes, and the grinding device inside automatically starts, performing grinding and cleaning of the workpiece. After grinding and cleaning is completed, the cabinet automatically opens again. Driven by the drive assembly, the hook removes the processed workpiece from the cabinet, allowing it to be unloaded. A new workpiece can then be installed, and the process is repeated to achieve continuous grinding and cleaning.

[0004] Regarding the aforementioned technologies, existing grinding and cleaning machines can automatically feed workpieces into the grinding and cleaning cabinet for automatic grinding and cleaning processing. However, each time, it is still necessary to manually or automatically load the workpiece onto the hook. When installing or removing workpieces, there are no workpieces in the grinding and cleaning cabinet for grinding and cleaning processing, which results in a long idle time in the grinding and cleaning cabinet. When the time for installing or removing workpieces is long, this will further extend the idle time of the grinding and cleaning cabinet, which will affect the processing efficiency of the grinding and cleaning machine. Summary of the Invention

[0005] This application provides an environmentally friendly integrated suspended grinding and sweeping machine, the purpose of which is to reduce the impact of installing or removing workpieces on the processing efficiency of the grinding and sweeping machine and improve the processing efficiency of the grinding and sweeping machine.

[0006] The environmentally friendly integrated suspended grinding and sweeping machine provided in this application adopts the following technical solution:

[0007] An environmentally friendly integrated suspended grinding and sweeping machine includes a grinding and sweeping cabinet. A drive shaft is installed inside the grinding and sweeping cabinet, and a rotation drive component is installed on the cabinet to drive the drive shaft to rotate. The grinding and sweeping cabinet also includes several lifting cabinets, at least two in number. Each lifting cabinet contains a hook, and a rotation drive component is installed on the lifting cabinet to drive the hook to rotate. The lifting cabinets are arranged at intervals along the circumference of the drive shaft, and each lifting cabinet is connected to the drive shaft. The lifting cabinets are slidably connected to the inner wall of the grinding and sweeping cabinet along the circumference of the drive shaft. The side wall of the grinding and sweeping cabinet has a grinding port and a loading port spaced apart. One opening of one lifting cabinet communicates with the grinding port, and another opening of the lifting cabinet communicates with the loading port. A grinding and sweeping mechanism is installed on the outside of the grinding and sweeping cabinet. The grinding and sweeping mechanism includes several grinding tools, and the discharge ports of the grinding tools are all oriented towards the grinding and sweeping port.

[0008] By adopting the above technical solution, firstly, the grinding and cleaning cabinet has a loading port and a grinding and cleaning port, while a grinding and cleaning device is installed on the outside of the cabinet, with the discharge port of the grinding and cleaning device facing the grinding and cleaning port. This structural arrangement allows workpieces to be installed inside the grinding and cleaning cabinet through the loading port, while the grinding and cleaning device can throw the grinding and cleaning material into the cabinet through the grinding and cleaning port, thereby performing grinding and cleaning processing on the workpieces.

[0009] Secondly, the grinding cabinet is equipped with a lifting cabinet, which contains a hook and a self-rotation drive. The hook can suspend the workpiece, and the self-rotation drive can drive the hook to rotate. During the grinding process, the workpiece is rotated by the self-rotation drive to ensure that all sides of the workpiece can be processed.

[0010] Several lifting cabinets are provided. One of these cabinets has its opening connected to the abrasion / sweeping port, while another cabinet's opening is connected to the loading port. When the opening of a lifting cabinet is connected to the abrasion / sweeping port, the cabinet is in the abrasion / sweeping station, allowing the workpiece inside to undergo abrasion / sweeping processing. When the opening of a lifting cabinet is connected to the loading port, the cabinet is in the loading station, allowing workpieces to be installed or removed.

[0011] Thanks to the coordination of the drive shaft and the shifting drive components, each hoisting cabinet can switch between the grinding and cleaning station and the workpiece loading station. For this reason, each time a hoisting cabinet is switched to the grinding and cleaning station for grinding operations, one of the hoisting cabinets must move to the workpiece loading station for loading and unloading. Therefore, the grinding and cleaning process and the workpiece loading and unloading can be carried out simultaneously. This reduces the impact of workpiece assembly and disassembly speed on the efficiency of the grinding and cleaning machine, thereby improving its processing efficiency.

[0012] Optionally, the grinding mechanism further includes a shot supply assembly, which includes a hopper located on the upper side of a plurality of grinding devices. A feeding pipe is provided between the hopper and the grinding devices, with both ends of the feeding pipe connected to the hopper and the grinding devices respectively. A feeding control valve is provided on the feeding pipe to control the flow rate of the grinding material in the feeding pipe.

[0013] By adopting the above technical solution, the shot supply assembly includes a hopper and a feed pipe. The hopper is used to store the abrasive material, and the feed pipe is used to transport the abrasive material into the corresponding abrasive. The feed control valve can control the flow rate of the abrasive material in the feed pipe. On the one hand, it can realize the supply of abrasive material; on the other hand, by controlling the flow rate of the feed pipe, it can also control the efficiency of the abrasive processing.

[0014] Optionally, the system also includes a shot collection mechanism, a bucket elevator, and a shot separator. The shot collection mechanism is located on the lower side of the abrasive cabinet, and its inlet is connected to the abrasive cabinet. When the opening of the hoisting cabinet is connected to the abrasive outlet, the hoisting cabinet is connected to the shot collection mechanism, and the outlet of the shot collection mechanism is connected to the inlet of the bucket elevator. The shot separator is located on the upper side of the hopper, and the outlet of the bucket elevator is connected to the inlet of the shot separator. A circulating shot return pipe for conveying abrasive materials is provided between the shot separator and the hopper. Both ends of the circulating shot return pipe are connected to the outlet of the shot separator and the inlet of the hopper, respectively. A dust collector is also connected to the side wall of the circulating shot return pipe.

[0015] By adopting the above technical solution, the shot collection mechanism, bucket elevator, shot separator, circulating shot return pipe, and hopper are sequentially connected. The shot collection mechanism is used to recover the scouring material after grinding, the bucket elevator is used to transport the scouring material between the shot collection mechanism and the shot separator, the shot separator effectively separates the scouring material from impurities after grinding, and finally the circulating shot return pipe sends the clean scouring material back to the hopper, realizing the recycling of scouring material and reducing resource waste. A dust collector is connected to the side wall of the circulating shot return pipe. During the scouring material circulation process, the dust collector can effectively remove the dust carried by the scouring material, reducing environmental pollution and protecting the working environment.

[0016] Optionally, a sealing strip is provided between the side wall of the hoisting cabinet and the inner side wall of the abrasive cabinet. One side of the sealing strip is fixedly connected to the hoisting cabinet, and the other side of the sealing strip abuts against the inner side wall of the abrasive cabinet. The sealing strip is slidably connected to the inner side wall of the hoisting cabinet along the circumference of the drive shaft.

[0017] By adopting the above technical solution, a sealing strip is installed between the side wall of the hoisting cabinet and the inner side wall of the grinding cabinet, which provides good sealing performance, prevents the leakage of grinding material and dust during the grinding process, protects the working environment, and also improves the efficiency of grinding.

[0018] Optionally, the hoisting cabinet is further provided with an auxiliary hook, which is located below the hook in the vertical direction; a mounting plate is provided below the auxiliary hook, and lifting drive components are provided at both ends of the mounting plate in the length direction to drive the mounting plate to move in the vertical direction; an auxiliary turntable is provided between the auxiliary hook and the mounting plate, the auxiliary hook is mounted on the auxiliary turntable, and the auxiliary turntable is rotatably connected to the mounting plate, and the auxiliary turntable and the output shaft of the rotation drive component are coaxially arranged.

[0019] By adopting the above technical solution, firstly, the cooperation of the auxiliary hook, mounting plate and lifting assembly enables the auxiliary hook to move up and down in the vertical direction.

[0020] Secondly, when the auxiliary hook and the lifting hook are used together, the workpiece is suspended on the lifting hook and the auxiliary hook hooks the lower end of the workpiece. At this time, under the drive of the lifting drive, the auxiliary hook is pulled down. Therefore, the auxiliary hook and the lifting hook can reinforce the workpiece and prevent the workpiece from shaking or tilting during the grinding and cleaning process.

[0021] Optionally, the hoisting cabinet has concealed elongated holes through its two inner sidewalls, the length of which is vertical; each inner sidewall has a concealed plate, the length of which is vertical, which closes the corresponding concealed elongated hole and is slidably connected to the corresponding inner sidewall of the hoisting cabinet in the vertical direction; a mounting plate is located between two concealed plates, and both ends of the mounting plate are detachably connected to the corresponding concealed plates; a lifting drive is provided on the two outer sidewalls of the hoisting cabinet, the lifting drive being connected to the corresponding concealed plate through the corresponding concealed elongated hole, and the lifting drive being used to drive the corresponding concealed plate to move vertically.

[0022] By adopting the above technical solution, firstly, by setting up a hidden elongated hole, the lifting drive component can be installed on the outside of the hoisting cabinet, which reduces the complexity of the internal structure of the hoisting cabinet and prevents the lifting drive component from being affected by the abrasive material thrown out by the abrasive cleaner.

[0023] Secondly, the hidden elongated hole is sealed by the hidden plate, and the lifting drive is connected to the hidden plate, and the mounting plate is connected to the hidden plate. Therefore, this ensures the normal lifting function of the mounting plate, and on the other hand, it can prevent the abrasive material from entering the hidden groove, thus improving the sealing of the entire hoisting cabinet.

[0024] Optionally, the auxiliary hook is provided with a first abutment, which is detachably connected to the auxiliary turntable; the hook is provided with a second abutment, which is detachably connected to the output shaft of the self-rotation drive; the first abutment and the second abutment are arranged facing each other in the vertical direction, and the first abutment and the second abutment are located between the hook and the auxiliary hook.

[0025] By adopting the above technical solution, the first abutment on the auxiliary hook and the second abutment on the hook are arranged vertically opposite each other. The first abutment and the second abutment are located between the hook and the auxiliary hook. Therefore, when it is necessary to clamp the workpiece, the workpiece is placed between the first abutment and the second abutment. The first abutment is raised by the lifting drive, which can clamp the workpiece between the first abutment and the second abutment. This provides another way to install the workpiece.

[0026] Optionally, elastic pads are provided on opposite sides of both the first and second abutting members.

[0027] By adopting the above technical solution, elastic pads are provided on the opposite side of the first and second abutting parts. This design can provide a buffering effect, avoid direct contact between the workpiece and the first and second abutting parts, avoid damage to the workpiece surface during the fixing process, and also reduce wear on the first and second abutting parts themselves.

[0028] Optionally, the first abutting component includes a mounting post, the lower end of which is coaxially and detachably connected to the auxiliary turntable. A clearance groove is provided on the lower side of the mounting post, and the auxiliary hook is located in the clearance groove. A clamping component is provided at the upper end of the mounting post, the clamping component including an abutting post, the abutting post being coaxially arranged with the mounting post. An abutting groove is provided at the upper end of the mounting post, the abutting post and the abutting groove are inserted into each other, the abutting post is slidably connected to the inner wall of the abutting groove along its own axial direction, and a clamping drive component is provided between the abutting post and the bottom of the abutting groove to drive the abutting post to move along its own axial direction.

[0029] By adopting the above technical solution, the first abutting component includes a mounting post, which is coaxially connected to the auxiliary turntable, allowing the auxiliary turntable and the mounting post to rotate synchronously. A clearance groove is provided on the lower side of the mounting post to accommodate an auxiliary hook, facilitating the installation of the mounting post and the auxiliary turntable. The clamping assembly at the upper end of the mounting post includes an abutting post, which is inserted into the mounting post via an abutting groove. The abutting post slides along its own axial direction against the inner wall of the abutting groove and is driven by a clamping drive. This design allows for precise control of the extension and retraction of the abutting post to accommodate workpieces of different thicknesses and achieve stable clamping. Therefore, after the upper end of the mounting post abuts against the workpiece via the lifting assembly, the abutting post is extended by the clamping drive, further clamping the workpiece and improving the stability of the workpiece installation.

[0030] Optionally, a reset element is further provided between the abutment post and the mounting post. The reset element includes a first reset ring and a second reset ring. The first reset ring is sleeved on the outside of the abutment post and is fixedly connected to the abutment post. The first reset ring is inserted into the abutment groove, and the first reset ring is slidably connected to the inner wall of the abutment groove along its own axial direction. The second reset ring is disposed in the abutment groove and is coaxially arranged with the mounting post. The second reset ring is fixedly connected to the inner wall of the abutment groove. The second reset ring is sleeved on the outside of the abutment post, and the abutment post is slidably connected to the inner wall of the second reset ring along its own axial direction. The first reset ring is located on the side of the second reset ring facing the clearance groove along its own axial direction.

[0031] By adopting the above technical solution, a reset component is set between the abutment post and the mounting post. The reset component includes a first reset ring and a second reset ring that are positioned opposite each other. The first reset ring is set on the abutment post, and the second reset ring is set in the abutment groove. Therefore, when the abutment post moves along its own axial direction, the second reset ring can limit the first reset ring and prevent the abutment post from sliding out of the abutment groove.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application, through the coordinated arrangement of several lifting cabinets, drive shafts and shifting drive components, enables the loading and unloading of workpieces in the grinding cabinet and the grinding and cleaning of workpieces to be carried out simultaneously. Therefore, it can reduce the impact of workpiece disassembly and assembly speed on the working efficiency of the grinding and cleaning machine, thereby improving the processing efficiency of the grinding and cleaning machine.

[0034] 2. This application, through the combined arrangement of auxiliary hooks and lifting drive components, can reinforce suspended workpieces and reduce the possibility of workpiece tilting or shaking during grinding.

[0035] 3. By using the cooperation of the first and second contacting parts, this application enables the hoisting cabinet to fix the workpiece not only by suspension but also by clamping, which increases the types of workpieces that the grinding and sweeping machine can process.

[0046] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0047] Example 1: An environmentally friendly integrated suspended sweeping machine, referring to... Figure 1 and Figure 2 It includes a scouting cabinet 1 and a scouting mechanism 3, with the scouting mechanism 3 located on the outside of the scouting cabinet 1.

[0048] Reference Figure 3 and Figure 4 The outer wall of the grinding cabinet 1 is provided with a grinding port 11 and a loading port 12, which are arranged facing each other horizontally. In this embodiment, the grinding cabinet 1 is cylindrical, and the grinding port 11 and the loading port 12 are arranged facing each other radially. The loading port 12 allows workpieces to be loaded into or removed from the grinding cabinet 1, while the grinding port 11 allows the workpieces inside the grinding cabinet 1 to be ground and cleaned.

[0049] Reference Figure 3 and Figure 4The abrasive cleaning cabinet 1 is equipped with a multi-station mechanism 2, which includes a drive shaft 21. The drive shaft 21 is arranged vertically, and its upper end is rotatably connected to the inner wall of the abrasive cleaning cabinet 1. The abrasive cleaning cabinet 1 is coaxially arranged with the drive shaft 21. A shifting drive component 22 is arranged on the upper side of the abrasive cleaning cabinet 1. The shifting drive component 22 is a motor, and its output shaft is coaxially connected to the drive shaft 21. Driven by the shifting drive component 22, the drive shaft 21 can rotate inside the abrasive cleaning cabinet 1.

[0050] Reference Figure 3 and Figure 4 The multi-station mechanism 2 also includes several lifting cabinets 23, with no fewer than two lifting cabinets 23. The lifting cabinets 23 are fixed to the outside of the drive shaft 21 and are arranged sequentially at intervals along the axial direction of the drive shaft 21. The lifting cabinets 23 are slidably connected to the inner wall of the abrasive cabinet 1 along the circumference of the drive shaft 21. With this structural arrangement, the lifting cabinets 23 can rotate inside the abrasive cabinet 1 when the drive shaft 21 rotates.

[0051] Reference Figure 3 and Figure 4 The opening of the lifting cabinet 23 is located on the side of the lifting cabinet 23 away from the drive shaft 21. Among the several lifting cabinets 23, one grinding cabinet 1 has an opening that communicates with the grinding port 11, and another grinding cabinet 1 has an opening that communicates with the loading port 12. The upper inner wall of the grinding cabinet 1 is equipped with a hook 24.

[0052] The hooks 24 allow each lifting cabinet 23 to suspend a workpiece. When the opening of the lifting cabinet 23 is connected to the abrasion port 11, the lifting cabinet 23 is in the abrasion position, allowing the workpiece inside to be abraded. When the opening of the lifting cabinet 23 is connected to the loading port 12, the lifting cabinet 23 is in the loading position, allowing workpieces to be installed or removed.

[0053] Reference Figure 3 and Figure 4 Due to the cooperation of the drive shaft 21 and the shifting drive component 22, each lifting cabinet 23 can switch between the grinding and polishing station and the assembly station. For this reason, this embodiment is equipped with two lifting cabinets 23. When one lifting cabinet 23 is in the grinding and polishing station, the other lifting cabinet 23 is in the assembly station. Therefore, each time they switch, the two lifting cabinets 23 rotate and change positions, which allows the assembly and grinding and polishing to be carried out synchronously, thereby speeding up the processing speed of the entire equipment.

[0054] Reference Figure 3 and Figure 4The lifting cabinet 23 is equipped with a rotation drive 231, the output shaft of which is vertically oriented and connected to the hook 24. The rotation drive 231 is a motor. Driven by the rotation drive 231, the hook 24 can rotate. During the grinding and sweeping operation, the hook 24 drives the workpiece to rotate, which allows the outer side of the workpiece to be ground and swept.

[0055] Reference Figure 3 and Figure 4 A sealing strip 232 is provided between the side wall of the lifting cabinet 23 and the inner side wall of the abrasive cabinet 1. One side of the sealing strip 232 is fixedly connected to the side wall of the lifting cabinet 23, and the other side of the sealing strip 232 abuts against the inner side wall of the abrasive cabinet 1. The sealing strip 232 is slidably connected to the inner side wall of the abrasive cabinet 1 along the circumference of the drive shaft 21. The sealing strip 232 can increase the sealing between the inner side wall of the lifting cabinet 23 and the abrasive cabinet 1. During the abrasive processing, the sealing strip 232 can prevent the abrasive material from getting stuck between the lifting cabinet 23 and the abrasive cabinet 1.

[0056] Reference Figure 1 and Figure 2 A scouting mechanism 3 is provided on the outside of the scouting cabinet 1. The scouting mechanism 3 includes several scouting devices 31, which are located on the outside of the scouting cabinet 1.

[0057] Reference Figure 2 and Figure 3 The abrasive cleaner 31 is positioned on the side of the abrasive cleaner cabinet 1 with the abrasive cleaning port 11, and the discharge port of the abrasive cleaner 31 is directly opposite the abrasive cleaning port 11 of the abrasive cleaner cabinet 1. When the opening of the corresponding lifting cabinet 23 is connected to the abrasive cleaning port 11, the abrasive cleaner 31 is activated, and the abrasive cleaner cabinet 1 can perform abrasive cleaning on the workpiece inside the lifting cabinet 23. Because the abrasive cleaner 31 is close to the abrasive cleaning port 11, a smaller power motor can be used for the abrasive cleaner 31, resulting in energy saving.

[0058] Reference Figure 1 and Figure 2 The grinding and shaving mechanism 3 also includes a shot supply assembly 32, which includes a hopper 321. The hopper 321 is located vertically above several grinding and shaving devices 31. A feed pipe 322 is provided between the hopper 321 and the grinding and shaving devices 31. The two ends of the feed pipe 322 are connected to the hopper 321 and the corresponding grinding and shaving device 31, respectively, and a feeding control valve is provided on the feed pipe 322. The hopper 321 is used to store grinding and shaving material, the feed pipe 322 is used to transport grinding and shaving material into the corresponding grinding and shaving device 31, and the feeding control valve can control the flow rate of grinding and shaving material in the feed pipe 322, thereby controlling the grinding and shaving processing efficiency.

[0059] Reference Figure 1 The grinding and sweeping machine also includes a shot collection mechanism 4, a bucket elevator 5, a shot separator 6, a dust collector 7, and a circulating shot return pipe 8.

[0060] Reference Figure 1 and Figure 4 The lower side wall of the hoisting cabinet 23 has a through-hole 233 for receiving the shot, and the lower side wall of the grinding cabinet 1 has a through-hole 13 for flowing through. When the opening of the hoisting cabinet 23 is connected to the grinding port 11, the receiving port 233 and the flowing hole 13 are connected. The shot receiving mechanism 4 is located below the grinding cabinet 1, and the feed inlet of the shot receiving mechanism 4 is connected to the flowing hole 13. After grinding, the grinding material passes through the receiving port 233 and the flowing hole 13 and enters the shot receiving mechanism 4, thus realizing the recovery of the grinding material. In this embodiment, the shot receiving mechanism 4 adopts a screw conveyor, a vibrating feed belt, or a conveyor belt.

[0061] Reference Figure 1 and Figure 2 The bucket elevator 5 is located outside the grinding cabinet 1 and is arranged vertically. The discharge port of the shot collection mechanism 4 is connected to the feed port of the bucket elevator 5. In this embodiment, the bucket elevator 5 is a belt-type bucket elevator or a chain-type bucket elevator. The shot collection mechanism 4 can feed the recovered grinding material into the bucket elevator 5.

[0062] Reference Figure 1 and Figure 2 The shot separator 6 is located vertically above the hopper 321 and is situated on one side of the bucket elevator 5, with its inlet connected to the outlet of the bucket elevator 5. The shot separator 6 is designed to remove sand from the abrasive material fed into the bucket elevator 5. In this embodiment, the shot separator 6 is either a magnetic separator or an air separator.

[0063] Reference Figure 1 and Figure 2 The circulating return pipe 8 is located between the hopper 321 and the shot separator 6, and is arranged vertically or inclined vertically. The upper end of the circulating return pipe 8 is connected to the discharge port of the shot separator 6, and the lower end of the circulating return pipe 8 is connected to the feed port of the hopper 321. The circulating return pipe 8 is designed to return the clean abrasive material separated by the shot separator 6 back to the hopper.

[0064] Reference Figure 1 The dust collector 7 is located on one side of the abrasive cabinet 1, and is connected to the circulating shot return pipe 8 via a pipe. In this embodiment, the dust collector 7 is either a bag filter or a cyclone separator.

[0065] Reference Figure 1Specifically, the dust collector 7 includes a dust collector body 71, which is a bag filter. The dust collector body 71 is connected to the circulating shot return pipe 8 via a pipeline. A vacuum pump or extraction pump is installed on the dust collector body 71 and is connected to the dust collector body 71, which can actively extract the gas inside the dust collector body 71, accelerating the airflow and the dust removal speed of the dust collector body 71. A vent 72 is installed on the upper side of the dust collector body 71, covering the outside of the vacuum pump or extraction pump. The vent 72 is detachably connected to the dust collector body 71 and has several ventilation holes, so the gas extracted by the vacuum pump or extraction pump can be directly discharged from the vent 72. Sound-absorbing cotton is placed on the inner wall of the vent 72 to reduce noise. The dust collector body 71 is also equipped with an explosion relief device, which can be an explosion relief valve or an explosion relief door. The explosion relief device prevents the metal dust from exploding due to heat, thus preventing damage to the dust collector 7 and improving the safety of the device.

[0066] Reference Figure 1 The grinding machine is also equipped with a control cabinet 100, which can control and monitor the operation of the entire equipment in real time.

[0067] Reference Figure 1 Through the coordinated operation of the shot collection mechanism 4, bucket elevator 5, shot separator 6, dust collector 7, and circulating shot return pipe 8, the scouring material after grinding and cleaning will roll into the shot collection mechanism 4 under its own gravity. Under the action of the shot collection mechanism 4, the scouring material will be fed into the bucket elevator 5. Lifted by the bucket elevator 5, the scouring material will fall into the shot separator 6, separating impurities from the scouring material. Afterward, the scouring material will be sent back to the hopper 321 through the circulating shot return pipe 8, thus achieving the recycling of the scouring material. While the scouring material is passing through the circulating shot return pipe 8, the dust collector 7 can absorb the dust and other residues in the scouring material, achieving dust removal.

[0068] The grinding machine of this application is integrally molded, has a compact structure, requires little installation space, and can be used in a variety of environments.

[0069] The implementation principle of this application embodiment is as follows: When performing the grinding and cleaning operation, under the drive of the shifting drive 22, the two hoisting cabinets 23 are respectively in the loading station and the grinding and cleaning station. The workpiece in the hoisting cabinet 23 in the grinding and cleaning station is ground and cleaned through the grinding and cleaning port 11. The workpiece after grinding and cleaning is disassembled in the hoisting cabinet 23 in the loading station through the loading port 12 and a new workpiece to be processed is loaded. The shifting drive 22 continues to drive and repeats the above operation to achieve continuous grinding and cleaning processing.

[0070] During the scouring process, the scouring material is fed into the shot collection mechanism 4. Driven by the shot collection mechanism 4, the scouring material is fed into the bucket elevator 5. The bucket elevator 5 lifts the scouring material and sends it into the shot separator 6. The shot separator 6 separates the scouring material from impurities. The separated scouring material is then sent back to the hopper 321 through the circulating shot return pipe 8, realizing the recycling of the scouring material. While the scouring material is passing through the circulating shot return pipe 8, the dust collector 7 removes the dust from the scouring material.

[0071] Example 2: An environmentally friendly integrated suspended sweeping machine, referring to... Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that: an auxiliary hook 25 is also provided inside the hoisting cabinet 23. The auxiliary hook 25 is set vertically on the lower side of the corresponding hook 24. An installation plate 251 is set on the lower side of the auxiliary hook 25. The length direction of the installation plate 251 is set horizontally. Lifting drive components 252 are provided between both ends of the length direction of the installation plate 251 and the corresponding inner side wall of the hoisting cabinet 23.

[0072] When the workpiece is suspended on the hook 24, the auxiliary hook 25 is located under the workpiece. At this time, the auxiliary hook 25 hooks the lower end of the workpiece. After that, under the drive of the lifting drive 252, the auxiliary hook 25 is pulled down. The auxiliary hook 25 and the hook 24 work together to reinforce the workpiece and prevent the workpiece from shaking or tilting during the grinding and cleaning process.

[0073] Reference Figure 5 and Figure 6 Hidden components 26 are provided at both ends of the mounting plate 251 along its length and between the inner sidewalls of the corresponding hanging cabinet 23. The hidden components 26 include a hidden plate 262. A hidden elongated hole 261 is provided on the inner sidewall of the corresponding hanging cabinet 23. The hidden elongated hole 261 is set along the vertical direction. The hidden plate 262 is set on the inner sidewall of the corresponding hanging cabinet 23. The hidden plate 262 closes the corresponding hidden elongated hole 261 and is slidably connected to the inner sidewall of the corresponding hanging cabinet 23 along the vertical direction.

[0074] Reference Figure 5 and Figure 6 The lifting drive component 252 uses a linear guide rail driven by a servo motor. The hidden plate 262 is connected to the corresponding lifting drive component 252, which enables the lifting drive component 252 to drive the corresponding hidden plate 262 to move vertically. One end of the mounting plate 251 along its length is connected to the corresponding hidden plate 262 by bolts, thus the mounting plate 251 and the lifting cabinet 23 are detachably connected. Therefore, under the drive of the lifting drive component 252, the mounting plate 251 and the auxiliary hook 25 can be raised and lowered vertically. During this process, the hidden plate 262 always closes the hidden elongated hole 261, which prevents the abrasive cleaner 31 from feeding the abrasive material into the hidden elongated hole 261.

[0075] Reference Figure 5 and Figure 6 An auxiliary turntable 253 is provided between the auxiliary hook 25 and the mounting plate 251. The auxiliary turntable 253 is coaxially arranged with the output shaft of the self-rotating drive component 231, and the lower side of the auxiliary turntable 253 is rotatably connected to the mounting plate 251, while the upper side of the auxiliary turntable 253 is detachably connected to the auxiliary hook 25. The auxiliary turntable 253 ensures that the automatic drive component can drive the workpiece to rotate.

[0076] Reference Figure 5 and Figure 6 An active turntable 241 is provided between the hook 24 and the self-rotation drive component 231. The active turntable 241 is coaxially arranged with the auxiliary turntable 253. The active turntable 241 is rotatably connected to the upper inner wall of the lifting cabinet 23. The upper side of the active turntable 241 is coaxially connected to the output shaft of the self-rotation drive component 231. The lower side of the active turntable 241 is bolted to the hook 24. The active turntable 241 enables the hook 24 to be detachably connected.

[0077] Reference Figure 5 and Figure 6 The lifting cabinet 23 is also equipped with a first contact member 9 and a second contact member 10. The first contact member 9 is located on the upper side of the auxiliary turntable 253 and is detachably connected to the auxiliary turntable 253. The second contact member 10 is located on the lower side of the active turntable 241 and is detachably connected to the active turntable 241. The first contact member 9 and the second contact member 10 are arranged facing each other vertically. When rod-shaped or columnar workpieces that are inconvenient to suspend are loaded into the lifting cabinet 23, the workpiece is placed between the first contact member 9 and the second contact member 10. Driven by the lifting drive member 252, the workpiece will abut against the first contact member 9 and the second contact member 10, thereby clamping the workpiece. At this time, the workpiece can be subjected to the grinding mechanism 3.

[0078] Reference Figure 5 and Figure 6 The first contact member 9 and the second contact member 10 have the same structure. This embodiment will be described using the first contact member 9 as an example.

[0079] Reference Figure 6 and Figure 7The first abutment 9 includes a mounting post 91, which is axially arranged in the vertical direction. A mounting ring 911 is fitted at the lower end of the mounting post 91. The mounting ring 911 is fixedly connected to the mounting post 91 and is coaxially arranged with the auxiliary turntable 253. Several through holes are opened through the mounting ring 911, and several mounting holes are opened on the auxiliary turntable 253. The inner wall of the mounting hole is provided with threads. The mounting hole and the through hole are arranged one-to-one and are connected to each other. By inserting bolts into the mounting hole and the corresponding through hole, a detachable connection between the first abutment 9 and the auxiliary turntable 253 can be achieved.

[0080] Reference Figure 6 and Figure 7 The lower end of the mounting post 91 is provided with a clearance groove 912, and the auxiliary hook 25 is located in the clearance groove 912. The clearance groove 912 provides clearance space for the auxiliary hook 25, which makes it possible to install the first abutment 9 without removing the auxiliary hook 25.

[0081] Reference Figure 6 and Figure 8 The mounting post 91 is provided with a clamping component 92 at its upper end. The clamping component 92 includes a clamping post 921. The mounting post 91 has a clamping groove 923 at its upper end. The clamping groove 923 is coaxially arranged with the clamping post 921. The clamping post 921 and the clamping groove 923 are inserted into each other. The clamping post 921 is slidably connected to the inner wall of the mounting hole in the vertical direction. A clamping drive member 93 is provided between the clamping post 921 and the bottom of the groove 923.

[0082] After the corresponding workpiece is installed onto the first contact member 9 and the second contact member 10, the first contact member 9 initially contacts the lower end of the workpiece under the drive of the lifting drive member 252. At this time, the pressing drive member 93 drives the contact column 921 to move upward, so that the contact column 921 can press against the workpiece and improve the stability of the workpiece fixation.

[0083] Reference Figure 6 and Figure 8 An elastic pad 922 is provided at the upper end of the contact post 921. The elastic pad 922 is provided to prevent the contact post 921 from directly contacting the workpiece and damaging the workpiece or the contact post 921.

[0084] Reference Figure 8 and Figure 9The clamping drive component 93 includes a drive gear ring 931. An annular groove 933 is formed on the outer wall of the mounting post 91, located between the contact groove 923 and the clearance groove 912 along the axial direction of the mounting post 91. The drive gear ring 931 is rotatably disposed within the annular groove 933 and is coaxially arranged with the mounting post 91. A drive lever 937 is provided on the outer wall of the drive gear ring 931. One end of the drive lever 937 is fixedly connected to the outer wall of the drive gear ring 931, and the other end of the drive lever 937 moves horizontally away from the drive lever 937. The drive lever 937 drives the drive gear ring 931 to rotate within the annular groove 933.

[0085] Reference Figure 8 and Figure 9 The clamping drive component 93 also includes a plurality of drive gears 932. A plurality of drive holes 934 are formed within the mounting post 91, with the drive holes 934 axially aligned with the axial direction of the mounting post 91. The drive holes 934 are evenly spaced along the circumference of the mounting post 91, and all drive holes 934 communicate with an annular groove 933. Each drive gear 932 corresponds to one drive hole 934, and the drive gear 932 is rotatably mounted within its corresponding drive hole 934. All drive gears 932 mesh with the drive gear ring 931. When the drive gear ring 931 rotates, the drive gears 932 can rotate within their corresponding drive holes 934.

[0086] Reference Figure 8 and Figure 9 The clamping drive component 93 also includes several drive rods 936, each drive rod 936 corresponding to a drive gear 932. The length of the drive rod 936 is along the axial direction of the mounting post 91. Each drive rod 936 includes a threaded rod 9361. One axial end of the drive gear 932 has a threaded hole 9321. The threaded hole 9321 is coaxial with the drive gear 932. The threaded rod 9361 is inserted into the corresponding threaded hole 9321, and the threaded rod 9361 is connected to the inner wall of the corresponding threaded hole 9321 by threads.

[0087] Reference Figure 8 and Figure 9 The drive rod 936 also includes a square rod 9362, which is coaxially arranged with the corresponding threaded rod 9361. The square rod 9362 is located at the end of the threaded rod 9361 facing the contact post 921, and the square rod 9362 is coaxially connected with the corresponding threaded rod 9361. The bottom of the contact groove 923 has several square holes 935, which correspond one-to-one with the threaded holes 9321, and are coaxially connected to each other. The square rod 9362 is inserted into the corresponding square hole 935, and the square rod 9362 slides along its own axial direction against the inner wall of the square hole 935.

[0088] Reference Figure 8and Figure 9 Due to the fit between the square hole 935 and the square rod 9362, the threaded rod 9361 cannot rotate when the drive gear 932 rotates. This means that the threaded rod 9361 can only move along its own axial direction, and the direction of movement of the threaded rod 9361 is related to the rotation direction of the drive gear 932. When the drive gear 932 rotates, the threaded rod 9361 moves along its own axial direction, thus enabling the threaded rod 9361 to drive the square rod 9362 to move along its own axial direction. Based on this principle, the drive lever 937 rotates the drive gear ring 931, which in turn rotates several drive gears 932, causing several drive rods 936 to move towards the abutment post 921. This causes the drive rods 936 to abut against the abutment post 921 and extend out of the abutment groove 923, thus realizing the driving function of the abutment post 921.

[0089] Reference Figure 8 and Figure 9 During the sliding process of the square rod 9362 along its own axis, the corresponding threaded rod 9361 is inserted into the corresponding square hole 935, and the threaded rod 9361 slides along its own axis to the inner wall of the corresponding square hole 935. This allows the entire drive rod 936 to move along its own axis.

[0090] Reference Figure 8 The clamping drive component 93 also includes a reset component 938, which includes a first reset ring 9381, a second reset ring 9382, and several reset springs 9383. The first reset ring 9381 is sleeved on the outside of the contact post 921 and is fixedly connected to the contact post 921. The first reset ring 9381 and the contact post 921 are inserted into each other, and the first reset ring 9381 is slidably connected to the inner wall of the contact hole along its own axial direction. The second reset ring 9382 is disposed in the contact groove 923, and the outer wall of the second reset ring 9382 is fixedly connected to the inner wall of the contact groove 923. The second reset ring 9382 is coaxially arranged with the mounting post 91 and is sleeved on the outside of the contact post 921. The contact post 921 is slidably connected to the inner wall of the second reset ring 9382 along its own axial direction. The first reset ring 9381 and the second reset ring 9382 are arranged facing each other in the vertical direction, with the second reset ring 9382 located above the first reset ring 9381 in the vertical direction. A plurality of reset springs 9383 are arranged between the first reset ring 9381 and the second reset ring 9382. The plurality of reset springs 9383 are arranged sequentially at intervals along the circumference of the contact post 921, with the two ends of the reset springs 9383 respectively contacting the first reset ring 9381 and the second reset ring 9382.

[0091] Reference Figure 8 and Figure 9When several drive rods 936 are reset, the reset spring 9383 will abut against the abutment post 921 to reset, which can realize the reset function of the abutment post 921.

[0092] The implementation principle of this application embodiment is as follows: When it is necessary to reinforce the suspended workpiece, an auxiliary hook 25 is installed in the suspension cabinet, the workpiece is suspended on the hook 24, the auxiliary hook 25 hooks the lower end of the workpiece, and then under the drive of the lifting drive 252, the auxiliary hook 25 pulls the workpiece downward. At this time, the hook 24 and the auxiliary hook 25 tighten the workpiece, thereby reinforcing the workpiece.

[0093] When it is necessary to fix the workpiece by clamping, on the basis of the above, install the first abutment 9 and the second abutment 10, place the workpiece between the first abutment 9 and the second abutment 10, and under the drive of the lifting drive 252, the second abutment 10 moves upward to abut the lower end of the workpiece. At this time, the workpiece is pre-clamped between the first abutment 9 and the second abutment 10. Then, rotate the drive lever 937 on the first abutment 9 and the second abutment 10 in sequence. The abutment post 921 of the first abutment 9 extends upward and the abutment post 921 of the second abutment 10 extends downward. At this time, the workpiece is clamped.

[0094] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
