Description

Technical Field

[0001] This utility model relates to the field of iron filings cleaning tools, and in particular to an iron filings cleaning shovel used in compressor piston production. Background Technology

[0002] During the processing of compressor piston production equipment, a large amount of iron filings are generated. After the iron filings are formed, they fall downwards onto the baffle. Although the baffle has a chip discharge port, it is difficult for the iron filings to enter accurately when they fall. In order to avoid the accumulation of iron filings from affecting normal production, personnel need to use a cleaning shovel to push the iron filings into the chip discharge port.

[0003] While existing cleaning shovels are strong and can clean over long distances, they still have other problems during use. For example, they lack angle adjustment, and the handle and blade are directly bolted together. When taller people hold them, they will raise one end of the handle high, causing the blade connected to the other end to tilt. If the tilt is too large, it will block the work surface, making it difficult to move the metal scraps. Moreover, it is not convenient to quickly replace the blade. Since the width of different areas on the baffle plate varies, if the blade is too long, it cannot reach narrower areas, and if the blade is too short, it takes a long time to clean wider areas. Disassembling and assembling the blade requires tools to remove its fixing bolts, which is time-consuming and laborious. To solve the above problems, we propose a metal scrap cleaning shovel for compressor piston production. Utility Model Content

[0004] The purpose of this invention is to provide a scraper for cleaning iron filings in compressor piston production, which solves the problems of existing scrapers lacking angle adjustment function and being inconvenient to replace the scraper blades.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a scraper for cleaning iron filings in compressor piston production, comprising a mounting plate, a fixing seat symmetrically mounted on the top of the mounting plate, a fixing frame provided on the top of the mounting plate, a handle bolted through one side of the fixing frame, screws mounted on both the front and back of the fixing frame, a locking nut threaded onto the surface of the screws, a scraper blade inserted into one side of the mounting plate, a connecting plate provided at the bottom of the mounting plate, a limit spring bolted between the top of the connecting plate and the mounting plate by a spring fixing piece, a limit pin welded to the top of the connecting plate, and the other end of the limit pin penetrating and extending into a through hole inside the scraper blade.

[0006] The above technical solution has an angle adjustment function, which can be adjusted according to the height of the personnel, making it convenient for personnel to hold and push the iron filings for cleaning. It is highly practical, and at the same time, it is easy to replace the scraper blade. The operation is simple and labor-saving, improving the work efficiency of personnel and providing good flexibility.

[0007] The present invention is further configured such that a spring washer that is slidably sleeved on the surface of the screw and fits against the fixed seat.

[0008] By adopting the above technical solution and setting the spring washer, the fixing effect of the lock nut after tightening can be improved, and it can play a role in shock prevention and loosening prevention.

[0009] The present invention is further configured such that an anti-slip sleeve is fixedly fitted onto the surface of the handle.

[0010] By adopting the above technical solution and setting the anti-slip sleeve, the anti-slip effect of the handle surface can be improved, preventing people from slipping their hands during handling and movement.

[0011] The present invention is further configured such that both the screw and the locking nut are made of stainless steel.

[0012] Using the above technical solution, the screw and locking nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0013] The present invention is further configured such that: guide rods are symmetrically welded to the bottom of the mounting plate, and the other end of the guide rods extends through to the outside of the connecting plate and is fitted with a stop block.

[0014] By adopting the above technical solution, the connecting plate can be limited by the setting of guide rods and stops to prevent the connecting plate from tilting during the up and down movement.

[0015] The present invention is further configured such that the number of the limiting spring, the limiting pin, and the through hole are all two.

[0016] By adopting the above technical solution, the stability of the blade after insertion and installation can be improved, and the overturning situation can be avoided.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model involves first loosening the locking nut with a tool, which releases the fixing of the frame. Then, a person can grasp the handle and pull it upwards. When the handle is pulled up to the appropriate angle, the fixing frame will rotate upwards. Once the handle is pulled to the appropriate angle, the locking nut can be tightened again. It has an angle adjustment function and can be adjusted according to the height of the person, making it convenient for the person to hold and push away iron filings. It is highly practical.

[0019] 2. This utility model allows for easy replacement of the scraper by placing one hand under the stop block and pulling down the connecting plate. As the connecting plate is pulled down, it not only deforms the limiting spring but also causes the limiting pin to separate from the through hole inside the scraper. After the connecting plate is pulled down to the bottom, the other hand can be used to grab the scraper and pull it outward. Then, a new scraper can be inserted inward to align the through hole with the lower through groove, and the connecting plate can be released. This makes it easy to replace the scraper, is simple and labor-saving, improves the work efficiency of personnel, and has good flexibility. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 , Figure 2 and Figure 3 A scraper for cleaning iron filings in compressor piston production includes a mounting plate 1. A fixed base 2 is symmetrically mounted on the top of the mounting plate 1. A fixed frame 3 is provided on the top of the mounting plate 1. A handle 13 is bolted through one side of the fixed frame 3. Screws 4 are mounted on both the front and back of the fixed frame 3. Locking nuts 5 are threaded onto the surface of the screws 4. By first loosening the locking nuts 5 with a tool, the fixed frame 3 is released from its fixation. Then, a person grasps the handle 13 and pulls it upwards. Pulling the handle 13 upwards causes the fixed frame 3 to rotate upwards. Once the handle 13 is pulled to a suitable angle, the locking nuts 5 are tightened again. The scraper has an angle adjustment function, allowing for appropriate adjustment according to the height of the person holding it, making it convenient for personnel to grip and push away iron filings. It is highly practical.

[0027] refer to Figure 3 The screw 4 has a spring washer 10 that slides on the surface and fits against the fixed seat 2. The spring washer 10 improves the fixing effect of the locking nut 5 after it is tightened, and plays a role in preventing shock and loosening.

[0028] refer to Figure 1 and Figure 2 An anti-slip sleeve 11 is fixedly fitted onto the surface of the handle 13. The anti-slip sleeve 11 improves the anti-slip effect of the surface of the handle 13 and prevents the hand from slipping during the gripping and moving process.

[0029] refer to Figure 1 and Figure 3 Both the screw 4 and the locking nut 5 are made of stainless steel, and have the characteristics of high strength, low density and excellent corrosion resistance.

[0030] Brief description of the usage process: First, use a tool to loosen the locking nut 5. After the locking nut 5 is loosened, it will release the fixation of the fixed frame 3. Then, the person grabs the handle 13 and pulls it up. When the handle 13 is pulled up, it will drive the fixed frame 3 to rotate upward. After the handle 13 is pulled up to the appropriate angle, tighten the locking nut 5 again.

[0031] Example 2:

[0032] refer to Figure 1 , Figure 2 and Figure 3 A scraper for cleaning iron filings in compressor piston production is disclosed. A scraper blade 6 is inserted into one side of a mounting plate 1. A connecting plate 7 is located at the bottom of the mounting plate 1. A limit spring 8 is bolted between the top of the connecting plate 7 and the mounting plate 1 via a spring fixing plate. A limit pin 9 is welded to the top of the connecting plate 7. The other end of the limit pin 9 passes through and extends into a through hole inside the scraper blade 6. By placing one hand under the stop block and pulling down the connecting plate 7, the limit spring 8 is deformed during the pull, and the limit pin 9 is separated from the through hole inside the scraper blade 6. After the connecting plate 7 is pulled down to the bottom, the scraper blade 6 is pulled outwards with the other hand. Then, a new scraper blade 6 is inserted inwards to align the through hole with the lower through groove, and the connecting plate 7 can be released. This facilitates the replacement of the scraper blade 6, is simple and labor-saving, improves work efficiency, and offers good flexibility.

[0033] refer to Figure 1 and Figure 2 Guide rods 12 are symmetrically welded to the bottom of the mounting plate 1. The other end of the guide rods 12 extends through to the outside of the connecting plate 7 and is equipped with a stop. The guide rods 12 and the stop can limit the connecting plate 7 and prevent it from tilting during the up and down movement.
