Description
Technical Field
[0001] This invention relates to the field of valve plate processing technology, specifically a valve plate finishing machine. Background Technology
[0002] Valve plates, classified by material, include steel valve plates, iron valve plates, and ceramic valve plates, etc. One existing type of compressor valve plate, X, is an iron valve plate... Figure 9 As shown, it is provided with a central through hole X-1.
[0003] After the aforementioned iron valve plate X is processed, it needs to be ground and polished. At this time, a polishing machine is used. A search revealed that the prior art, such as Chinese patent (authorization number: CN108890439B), discloses a roller-type valve plate polishing machine, which consists of a cylindrical body with open ends of a polygonal prism and a sealing part of a polygonal pyramid. This increases the probability of the valve plate colliding with the polishing roller. A polishing body assembly is installed on the inner wall of the polishing roller to increase the friction between the valve plate and the polishing body, enhance the polishing effect, and improve the polishing efficiency.
[0004] However, the aforementioned patents all involve putting multiple valve plates into the cylinder at once. After the valve plates are polished, they need to be retrieved one by one, which is very troublesome and time-consuming. Therefore, it is necessary to design a polishing machine that facilitates the loading and unloading of valve plates to solve the above problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a valve plate finishing machine, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A valve plate finishing machine includes a circular finishing shell, a material inlet on the top of the finishing shell, and multiple shell legs arranged in a rectangular array fixed at the bottom of the finishing shell.
[0008] The most significant design difference between this invention and the prior art is that a toggle frame is rotatably mounted inside the polished outer shell, and multiple iron valve plates with central through holes are mounted on the toggle frame.
[0009] In order to enable the rotation of the toggle bracket, a horizontally mounted motor is installed at the center of the front surface of the polished housing. The output shaft of the motor rotates out of the polished housing and is connected to the toggle bracket.
[0010] Specifically, in this invention, the actuating frame includes a mounting roller disposed inside the polished housing. One end of the mounting roller is fixed to the output shaft of the motor, and the other end is rotatably mounted at the center of the inner side of the rear surface of the polished housing. Multiple equally spaced mounting structures are detachably mounted on the mounting roller.
[0011] To enable the installation of the iron valve plate, the mounting structure includes a guide rod detachably mounted on the mounting roller, and the iron valve plate is fitted onto the guide rod through a central through hole thereon.
[0012] To facilitate the installation and removal of the guide rod, a slot is provided on the mounting roller, and the mounting end of the guide rod is inserted into the slot, while the free end extends to the inner wall of the polished outer shell.
[0013] In order to polish the central through hole on the iron valve plate, the outer surface of the guide rod is wrapped with a layer of sandpaper.
[0014] In order to attract iron filings inside the polished casing, the guide rod has a mounting cavity from the free end to the closed end. The cavity wall has multiple equally spaced long grooves that penetrate sandpaper outwards. A detachable magnetic rod is installed inside the mounting cavity.
[0015] In order to facilitate the assembly and disassembly of the magnet rod, a threaded hole is provided at the center of the closed end of the guide rod, and a threaded post is fixed at one end of the magnet rod near the threaded hole, and the threaded post is screwed into the threaded hole.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. In this invention, multiple iron valve plates are mounted on guide rods. Abrasive is added into the polished outer shell through the material inlet. The motor drives the multiple guide rods to rotate, and the guide rods act as stirring rods to polish each iron valve plate. After polishing, the multiple iron valve plates on one guide rod can be disassembled from the material inlet, making it very convenient to install and remove the iron valve plates.
[0018] 2. The sandpaper of this invention can polish the central through hole on the iron valve plate. Then, in conjunction with a magnetic rod, it can attract the iron filings generated during polishing. The magnetic rod can then be removed from the guide rod to clean the iron filings adsorbed on the magnetic rod.
[0019] In summary, the most significant contribution of this invention is that it combines convenient loading and unloading of iron valve plates with easy cleaning of scrap iron filings, featuring a simple structure and high practicality. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0031] like Figure 1-3 As shown, the present invention provides a valve plate finishing machine, including a circular finishing shell 1, a material port 1-1 opened on the top of the finishing shell 1, and a plurality of shell legs 2 arranged in a rectangular array fixed at the bottom of the finishing shell 1.
[0032] like Figure 4 As shown, the most significant design difference between this invention and the prior art is that a toggle frame is rotatably installed inside the polished outer shell 1, and multiple iron valve plates X with central through holes X-1 are installed on the toggle frame.
[0033] like Figure 2-3 As shown, in order to realize the rotation of the toggle frame, a horizontally mounted motor 3 is installed at the center of the front surface of the polished housing 1. The motor 3 is powered by an external power source. The output shaft of the motor 3 rotates out of the polished housing 1 and connects to the toggle frame. A shaft hole is opened at the center of the front surface of the polished housing 1, and a bearing is installed in the shaft hole. The output shaft of the motor 3 is installed on the bearing. The toggle frame includes a mounting roller 4 set inside the polished housing 1. One end of the mounting roller 4 is fixed to the output shaft of the motor 3, and the other end is rotatably mounted at the center of the inner side of the rear surface of the polished housing 1. A shaft hole is also opened at the center of the rear surface of the polished housing 1, and a bearing is installed in the shaft hole. A fixed shaft is fixed to the other end of the mounting roller 4 and is installed on the bearing. Multiple equally spaced mounting structures are detachably mounted on the mounting roller 4.
[0034] like Figure 1 , Figure 5-7As shown, in order to install the iron valve plate X, the installation structure includes a guide rod 5 that is detachably mounted on the installation roller 4. The iron valve plate X is sleeved on the guide rod 5 through the central through hole X-1 on it. Multiple iron valve plates X are sleeved on the guide rod 5. Abrasive is added into the polished housing 1 through the material port 1-1. The multiple guide rods 5 are driven to rotate by the motor 3. The guide rod 5 acts as a stirring rod to polish each iron valve plate X. After polishing, the multiple iron valve plates X on one guide rod 5 can be removed from the material port 1-1. The installation and removal of the iron valve plates X is very convenient.
[0035] like Figure 5 As shown, to facilitate the installation and removal of the guide rod 5, a slot 4-1 is provided on the mounting roller 4. The mounting end of the guide rod 5 is inserted into the slot 4-1, and the free end extends to the inner wall of the polished housing 1. This ensures that when the guide rod 5 rotates, the free end of the guide rod 5 remains against the inner wall of the polished housing 1, preventing the iron valve plate X from detaching from the guide rod 5 and falling into the polished housing 1. In use, abrasive is fed into the polished housing 1 through the feed port 1-1, and then the polished iron valve plate X is fitted onto the guide rod 5 located at the feed port 1-1. The thickness of the iron valve plate X should be less than the length of the guide rod 5. This allows each iron valve plate X to slide on the guide rod 5 when the guide rod 5 rotates, enabling the abrasive to move within the gaps between the iron valve plates X and to fully polish the iron valve plates X. Then, the motor 3 can be connected to an external power source and started, driving the mounting roller 4 to rotate, which in turn drives the iron valve plates X on each guide rod 5 to rotate in the abrasive. The guide rod 5 and the iron valve plates X act as stirring rods, fully polishing the iron valve plates X, and with higher efficiency.
[0036] like Figure 6 As shown, in order to polish the central through hole X-1 on the iron valve plate X, a layer of sandpaper 6 is wrapped around the outer surface of the guide rod 5. The sandpaper 6 can polish the central through hole X-1 on the iron valve plate X. Then, the magnetic rod 7 is used to attract the iron filings generated during polishing. The magnetic rod 7 is then removed from the guide rod 5 to clean the iron filings attracted to the magnetic rod 7.
[0037] When the multiple iron valve plates X on a guide rod 5 are polished and located at the material inlet 1-1, the motor 3 stops working. The worker can then reach into the polished housing 1 and pull the polished iron valve plates X on the guide rod 5 directly upwards out of the polished housing 1. Alternatively, they can... Figure 8 In this way, a limiting ring 9 is fixed at the mounting end of the guide rod 5. The outer diameter of the limiting ring 9 is larger than the inner diameter of the central through hole X-1 of the iron valve plate X. This can achieve the bearing of each iron valve plate X. After the iron valve plate X is exposed to light, the guide rod 5 is lifted directly. The guide rod 5 is disengaged from the slot 4-1. The polished outer shell 1 is lifted upward together through the limiting ring 9 and the multiple iron valve plates X on the guide rod 5.
[0038] like Figure 7As shown, in order to attract iron filings inside the polished housing 1, the free end of the guide rod 5 is provided with an installation cavity from the closed end. Multiple equally spaced long grooves 5-1 are provided on the cavity wall of the installation cavity. The long grooves 5-1 penetrate the sandpaper 6 outward. A detachable magnetic rod 7 is installed inside the installation cavity.
[0039] like Figure 6 As shown, in order to assemble and disassemble the magnet rod 7, a threaded hole is provided at the center of the closed end of the guide rod 5. A threaded post 8 is fixed at one end of the magnet rod 7 near the threaded hole. The threaded post 8 is screwed into the threaded hole. When the iron valve plate X is polished, the generated debris will enter the installation cavity from the long groove 5-1 and be attracted to the surface of the magnet rod 7. When there are too many iron filings on the magnet rod 7, the guide rod 5 is removed from the rotating roller. Then, one hand holds the guide rod 5, and the fingers of the other hand are inserted into the installation cavity to pinch the magnet rod 7 and rotate it, which drives the threaded post 8 to rotate until the threaded post 8 is disengaged from the threaded hole. This realizes the disassembly of the magnet rod 7 in the installation cavity. Pulling the magnet rod 7 out of the installation cavity allows the iron filings to be cleaned. After that, the magnet rod 7 is inserted into the installation cavity, the threaded post 8 is screwed into the threaded hole, and the guide rod 5 is inserted into the slot 4-1.
[0040] In summary, the most significant contribution of this invention is that it combines convenient loading and unloading of iron valve plates with easy cleaning of scrap iron filings, featuring a simple structure and high practicality.
[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
