Description

Technical Field

[0001] This invention belongs to the technical field of compressor housing processing, and specifically relates to a burr-free processing device and method for refrigeration compressor housing. Background Technology

[0002] A refrigeration compressor is a mechanical device used to compress and transport gaseous refrigerant. It is the core and heart of a refrigeration system. The capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system. In a sense, the design and matching of a refrigeration system is to bring out the capacity of the compressor. Therefore, the refrigeration industry in all countries has invested a lot of effort in the research of refrigeration compressors. New research directions and research results are constantly emerging. When producing this type of compressor, each of its upper-end components is processed and produced by specialized production equipment. Among them, the production tools for the outer casing are the most numerous.

[0003] In the production of compressor housings, die casting is generally used. This process is efficient and produces relatively high-quality finished products. However, a drawback of this method is that uncut metal burrs may remain on the edges of the housing after die casting. These burrs can affect the later assembly of the compressor and its normal operation. Therefore, modern refrigeration compressor production facilities are equipped with burr removal equipment to specifically remove burrs from the compressor housings after production.

[0004] However, existing burr-free machining devices for refrigeration compressor casings still have the following drawbacks during use:

[0005] 1. When using existing compressor housing burr removal processing equipment, manual grinding is still required when grinding burrs on die-cast compressor housings. Alternatively, an automatic grinding device can be installed at the top. However, when encountering disc-shaped housings such as compressor end caps, the operator still needs to rotate the die-cast housing so that the grinding structure of the device can fully contact the burrs on the edge of the housing, thereby reducing the amount of burrs that need to be ground off. This design increases the workload of the operator and affects the processing efficiency of the compressor housing.

[0006] 2. After the existing compressor burr removal processing equipment performs die casting and burr removal on the compressor housing, most of the burrs are ground off. As a result, a large amount of burr dust will accumulate on the equipment. If it is not cleaned for a long time, it will affect the normal use of the equipment. Manual cleaning is very inconvenient due to the large number of components on the equipment, thus reducing the ease of use of the equipment.

[0007] Therefore, it is necessary to invent a burr-free processing device and a burr-free processing method for the housing of a refrigeration compressor to solve the above problems. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a burr-free machining device and method for refrigeration compressor housings, thereby resolving the issues raised in the background section.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a burr-free processing device and a burr-free processing method for a refrigeration compressor housing, comprising a processing table, wherein the top of the processing table is equipped with a housing edge burr removal mechanism, a dust removal component, and a die-casting processing mechanism;

[0010] The shell edge burr removal mechanism includes first limiting slide grooves on both sides of the top of the processing table. Support frames are slidably connected to the inner walls of both first limiting slide grooves. An arc-shaped mounting bracket is fixed to one end of each of the two support frames. A second limiting slide groove is opened on one side of each of the two arc-shaped mounting brackets. A first mounting groove is opened on the inner wall of one end of each of the two support frames. An arc-shaped moving strip is slidably connected to the inner wall of one of the second limiting slide grooves. A toothed ring is fixed to one side of the outer wall of the arc-shaped moving strip. Gears are rotatably connected to the inner walls of both first mounting grooves. Connecting grooves are opened on one side of each of the two support frames located at one end of each of the two first mounting grooves. The inner walls of the two connecting grooves communicate with the inner walls of the two second limiting slide grooves, and the outer walls of the two gears pass through the inner walls of the two connecting grooves and mesh with the outer walls of the toothed rings. A connecting frame is fixed to one side of the arc-shaped moving strip, and a grinding wheel is rotatably connected to the bottom of the connecting frame.

[0011] Preferably, a first motor is installed at the lower edge of one side of the connecting frame, and one end of the grinding wheel passes through the outer wall of one side of the connecting frame and is fixedly connected to the output end of the first motor. One end of each of the two gears passes through the bottom of the two support frames and is fixedly connected to a second motor.

[0012] Preferably, the inner wall of the processing table is rotatably connected to a bidirectional lead screw, and the outer walls of both ends of the bidirectional lead screw pass through the inner walls of the two first limiting slide grooves and are threadedly connected to the inner walls of the two support frames. A third motor is installed at one end of the processing table, and one end of the bidirectional lead screw passes through the outer wall of one side of the processing table and is fixedly connected to the output end of the third motor.

[0013] Preferably, the dust removal assembly includes a dust discharge groove formed on one side of the outer wall of the processing table, a second mounting groove formed at both ends of the inner wall of the processing table, and multiple air outlet grooves formed at equal distances on both sides of the top of the processing table, and the inner wall of each second mounting groove is connected to the inner wall of the multiple air outlet grooves respectively.

[0014] Preferably, a fan is installed at one edge of the inner wall of each of the two second mounting slots, and through slots are provided on both sides of the bottom of the processing table, and the inner walls of the two through slots are respectively connected to the inner walls of one end of the two first limiting slides.

[0015] Preferably, the die-casting processing mechanism includes three connecting holes on one side of the top of the processing table, and a forming mold is fixedly installed at the middle position of the top of the processing table, wherein hydraulic rods are installed on the inner walls of two of the connecting holes.

[0016] Preferably, a support plate is fixedly connected to the top of the two hydraulic rods, a die-casting module is fixedly provided on one side of the bottom of the support plate, and a limiting rod is fixedly provided on the other side of the bottom of the support plate, with the outer wall of the limiting rod interlocking with the inner wall of another connecting hole.

[0017] Preferably, a control panel is installed on one side of the processing table, and the first motor, second motor, third motor and fan are all electrically connected to an external power supply through the control panel.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention utilizes a shell edge burr removal mechanism. A third motor rotates a bidirectional lead screw in the first limiting slide groove, causing two support frames to move relative to each other within the two first limiting slide grooves until the two arc-shaped mounting frames align. At this point, the outer wall of the grinding wheel contacts the edge of the formed shell. The first motor on the connecting frame is then activated, causing the grinding wheel to rotate and remove the burrs. Simultaneously, two second motors rotate gears, which, through a gear meshing with a gear ring in the connecting groove, slide the arc-shaped moving strip in the connected second limiting slide groove. This allows the connecting frame at its upper end, carrying the grinding wheel, to move and grind around the edge of the shell, thoroughly removing the burrs from the outer edge. No manual grinding is required, and burr removal can be achieved immediately after die-casting, improving the processing efficiency of the compressor shell.

[0020] 2. This invention, by setting up a dust removal component, activates the fan in the second mounting slot, causing it to expel air through the air outlet slot, thereby blowing the dust from the grinding into the dust discharge slot, and then discharging and collecting it through the dust discharge slot. The bottom of the inner wall of the dust discharge slot is inclined, making it easier for the dust to be discharged. Some of the dust blown into the first limiting slide slots at both ends is directly discharged through the through slot at the bottom of the first limiting slide slot, so that the inside of the first limiting slide slot will not accumulate dust, thus not affecting the normal movement of the support frame and improving the convenience of using the device.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figure 1-7 The apparatus and method for burr-free processing of refrigeration compressor housing shown herein include a processing table 1, characterized in that: a housing edge burr removal mechanism 2, a dust removal component 3, and a die-casting processing mechanism 4 are installed on the top of the processing table 1.

[0033] The shell edge burr removal mechanism 2 includes first limiting slide grooves 201 formed on both sides of the top of the processing table 1. Support frames 202 are slidably connected to the inner walls of both first limiting slide grooves 201. An arc-shaped mounting bracket 203 is fixedly provided at one end of each of the two support frames 202. A second limiting slide groove 204 is formed on one side of each of the two arc-shaped mounting brackets 203. A first mounting groove 205 is formed on the inner wall of one end of each of the two support frames 202. An arc-shaped moving strip 206 is slidably connected to the inner wall of one of the second limiting slide grooves 204. One side of the outer wall of the arc-shaped moving strip 206... A gear ring 207 is fixedly provided. Gears 208 are rotatably connected to the inner walls of the two first mounting grooves 205. One end of each of the two support frames 202 is located on one side of the two first mounting grooves 205 and a connecting groove 209 is provided. The inner walls of the two connecting grooves 209 are respectively connected to the inner walls of the two second limiting slide grooves 204. The outer walls of the two gears 208 respectively pass through the inner walls of the two connecting grooves 209 and mesh with the outer walls of the gear ring 207. A connecting frame 210 is fixedly provided on one side of the arc-shaped moving bar 206. A grinding wheel 211 is rotatably connected to the bottom of the connecting frame 210.

[0034] In use, the metal raw material produced from the compressor housing is placed on the upper end of the forming mold 402. After die casting by the die casting processing mechanism 4, burrs are most likely to be left on the edge of the housing. At this time, the third motor 215 is started to rotate the bidirectional lead screw 214 in the first limit slide groove 201, thereby moving the two support frames 202 relative to each other in the two first limit slide grooves 201 until the two arc-shaped mounting frames 203 are aligned with each other as shown in the instruction manual. Figure 4As shown, the two second limiting slide grooves 204 on the casing are connected to each other. At this time, the outer wall of the grinding wheel 211 just contacts the edge of the molded casing. The first motor 212 on the connecting frame 210 is started, causing the grinding wheel 211 to rotate and grind off the burrs. At the same time, the two second motors 213 are started to rotate the gear 208. Then, one gear 208 passes through the connecting groove 209 and meshes with the toothed ring 207, which in turn slides the arc-shaped moving strip 206 in the connected second limiting slide groove 204. The rotation speed of the gears 208 at both ends is just matched with the moving speed of the toothed ring 207. This causes the toothed ring 207 to rotate cyclically around the two connected second limiting slide grooves 204 with the arc-shaped moving strip 206. The connecting frame 210 at the upper end moves around the edge of the casing with the grinding wheel 211 to grind, thus thoroughly cleaning the burrs on the outer edge. No manual grinding is required, and the burr removal can be achieved immediately after die casting, improving the processing efficiency of the compressor casing.

[0035] A first motor 212 is installed at the lower edge of one side of the connecting frame 210, and one end of the grinding wheel 211 passes through the outer wall of one side of the connecting frame 210 and is fixedly connected to the output end of the first motor 212. One end of each of the two gears 208 passes through the bottom of the two support frames 202 and is fixedly connected to a second motor 213. When the two second motors 213 drive the rotating gear 208 to rotate, when the gear ring 207 slides from one second limit slide groove 204 to another second limit slide groove 204 with the arc-shaped moving strip 206, the gear 208 on that side can just mesh with the gear ring 207, thereby meshing and driving the arc-shaped moving strip 206 to continue sliding, thereby carrying the connecting frame 210 and the grinding wheel 211 to perform circumferential motion, so as to achieve thorough edge grinding of the circular compressor housing.

[0036] The inner wall of the processing table 1 is rotatably connected with a bidirectional lead screw 214, and the outer walls of both ends of the bidirectional lead screw 214 pass through the inner walls of the two first limiting slide grooves 201 and are threadedly connected to the inner walls of the two support frames 202. A third motor 215 is installed at one end of the processing table 1, and one end of the bidirectional lead screw 214 passes through the outer wall of one side of the processing table 1 and is fixedly connected to the output end of the third motor 215.

[0037] Furthermore, the dust removal assembly 3 includes a dust discharge trough 301 formed on one side of the outer wall of the processing table 1, second mounting grooves 302 formed at both ends of the inner wall of the processing table 1, and multiple air outlet grooves 303 formed at equal intervals on both sides of the top of the processing table 1. The inner wall of each second mounting groove 302 is connected to the inner wall of the multiple air outlet grooves 303, and the air outlet grooves 303 are formed on one side of the processing table 1 as shown in the attached instruction manual. Figure 5 As shown, its side is semi-circular, which can concentrate the airflow in the middle area, so that the dust can be fully blown into the dust discharge trough 301 for collection.

[0038] Fans 304 are installed at one edge of the inner wall of each of the two second mounting slots 302. Through slots 305 are opened on both sides of the bottom of the processing table 1. The inner walls of the two through slots 305 are respectively connected to the inner walls of one end of the two first limiting slides 201. After the compressor housing is die-cast and the outer wall is deburred, the fans 304 in the second mounting slots 302 are started, so that they can blow air out through the air outlet slots 303, thereby blowing the dust from the grinding into the dust discharge slots 301 and discharging and collecting it through the dust discharge slots 301. The bottom of the inner wall of the dust discharge slots 301 is inclined, making it easier for the dust to be discharged. Some of the dust blown into the first limiting slides 201 at both ends is directly discharged through the through slots 305 at the bottom of the first limiting slides 201, so that dust will not accumulate inside the first limiting slides 201, and will not affect the normal movement of the support frame 202, thus improving the convenience of using the device.

[0039] Furthermore, the die-casting processing mechanism 4 includes three connecting holes 401 on one side of the top of the processing table 1. A forming mold 402 is fixedly installed at the middle position of the top of the processing table 1. Hydraulic rods 403 are installed on the inner walls of two of the connecting holes 401, as shown in the attached instruction manual. Figure 5 As shown, the molding die 402 has a certain limiting effect on the molded shell at its edge, which makes it highly stable during the grinding and deburring process and not easily ground out of the area.

[0040] A support plate 404 is fixedly connected to the top of two hydraulic rods 403. A die-casting module 405 is fixedly installed on one side of the bottom of the support plate 404, and a limiting rod 406 is fixedly installed on the other side of the bottom of the support plate 404. The outer wall of the limiting rod 406 is inserted and connected to the inner wall of another connecting hole 401. When die-casting the shell, the hydraulic rods 403 are activated to lower the support plate 404, and then lower the die-casting module 405 to die-cast the metal raw material on the forming mold 402, so that it can be quickly formed.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
