Description

Technical Field

[0001] The present invention belongs to the technical field of compressor manufacturing, and specifically relates to a processing device and method for compressor component billets. Background Art

[0002] An automotive air-conditioning compressor is the heart of an automotive air-conditioning refrigeration system, and plays a role in compressing and conveying refrigerant vapor. Most parts of the compressor are castings, such as static and dynamic discs, cylinder heads, and covers. After the production of these parts, there are riser parts, as Figure 13 shown. The riser parts need to be cut off before subsequent finish machining. The existing sawing of compressor casting risers has the following problems:

[0003] 1. In the existing sawing operation of compressor castings, the casting is clamped on a three-jaw chuck, and the riser is sawed off by a saw blade. Each time, the casting needs to be clamped before sawing can be completed. Therefore, the processing efficiency of the casting riser needs to be further improved.

[0004] 2. In the existing sawing operation of compressor castings, lubricating oil is used for cooling and lubrication during sawing. However, the chips and the filter screen cannot be efficiently separated, resulting in inefficient utilization of the lubricating oil. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to solve the operations of cutting off the riser of the compressor casting and separating the chips and the lubricating oil.

[0006] To solve the above technical problems, the inventor obtained the technical solution of the present invention through practice and summary. The present invention adopts the following technical solution:

A sawing cover and a sawing motor are installed on the vertical slide table. The output end of the sawing motor is installed with a saw blade;

[0011] The aggregate bin is installed on the frame and is located below the sawing assembly. A filter screen is arranged on the material receiving side of the aggregate bin, and a recycling bin is independently arranged below the filter screen.

[0012] In a more optimized solution, a longitudinal slide rail and a longitudinal motor are installed on the frame. The output end of the longitudinal motor is equipped with a longitudinal lead screw, which is rotatably installed on the frame. A longitudinal slide table is matched with the longitudinal lead screw. A rotary frame and a rotary motor for driving the rotary movement of the rotary frame seat are rotatably installed on the longitudinal slide table. The rotary part is of a cylindrical structure and is internally provided with a clamping part for clamping the stock head.

[0013] The casting clamping assembly is rotatably installed on the rotating table. The casting clamping assembly is a three-jaw pneumatic chuck. A first driven part is cooperatively installed on the outside of the casting clamping assembly, and a second driven part is installed on the outside of the rotary frame. The first driven part and the second driven part are selectively adapted to form a transmission cooperation between the casting clamping assembly and the rotary frame. The axis of the casting clamping assembly coincides with the axes of the longitudinal motor and the rotary frame.

[0014] In a more optimized solution, the clamping part includes a first clamping part and a second clamping part arranged in the cylindrical structure. The first clamping part and the second clamping part clamp the stock head from the inside and the outside respectively.

[0015] The first clamping part includes an inner pressure sleeve. The inside of the inner pressure sleeve is a hollow structure. A first stepped hole is evenly arranged on the side of the inner pressure sleeve, and an inner pressure column is slidably fitted in the first stepped hole.

[0016] The second clamping part includes an outer pressure sleeve. The inside of the outer pressure sleeve is a hollow structure. A second stepped hole is evenly arranged on the side of the outer pressure sleeve, and an outer pressure column is slidably fitted in the second stepped hole.

[0017] The inner pressure column and the outer pressure column are both arranged perpendicular to the stock head. The outer pressure sleeve and the inner pressure sleeve are interconnected. A rotating ring is rotatably installed on the outside of the rotary part. A pressure medium inlet and a pressure medium outlet are installed on the rotating ring. The pressure medium inlet and the pressure medium outlet are connected to a solenoid valve through a pipeline. The solenoid valve is connected to a medium pump through a first pipeline and to a filter through a second pipeline. The medium pump is installed in the medium tank.

[0018] In a more optimized solution, the clamping part further includes elastic top columns, which are distributed at the inner end of the rotary part between the inner pressure column and the outer pressure column. Each elastic top column includes a fixed sleeve and a top column body. A spring is installed in the fixed sleeve, and the top column body is slidably fitted in the fixed sleeve and its end face abuts against the spring.

[0019] In a more optimized solution, the area where the aggregate bin is located below the sawing assembly is the material receiving side. An inner concave opening is provided at the top of the material receiving side. An air pump and a connecting pipe are installed in the inner concave opening. A plurality of air supply ports are evenly distributed on the outer wall of the connecting pipe, and the air supply ports are used to convey the debris along the material receiving side to the bottom of the aggregate bin.

[0020] On the material receiving side, there are a material receiving slope, a filtering slope, and a blanking slope distributed from top to bottom in sequence. The inclination angle of the filtering slope is smaller than that of the material receiving slope. A recycling box is independently arranged below the filtering slope. There are gaps and a guiding frame located below the gaps on the filtering slope. A filter screen is slidably fitted in the gaps and the guiding frame. A lower mounting plate is installed on the aggregate box, a filtering motor is installed on the lower mounting plate, a cam disk is fixedly installed at the output end of the filtering motor, a connecting plate is attached below the cam disk, the connecting plate is connected to the filter screen through a connecting column, two guiding columns are inserted through the connecting plate, the two guiding columns are fixed on the guiding frame and the aggregate box, and spring members are distributed on the outer sides of the guiding columns. The spring members are located below the connecting plate.

[0021] In a more optimized solution, an inclined plate is installed inside the aggregate box, and a number of high-pressure air nozzles are evenly distributed on the inclined plate. The high-pressure air nozzles are arranged towards the filtering slope.

[0022] In a more optimized solution, a chip discharging port is arranged at the bottom of the aggregate box. Scrap curtains are arranged on both sides of the chip discharging port facing the running direction of the chip discharging chain and parallel to the running direction of the chip discharging chain. Chip discharging chains are distributed at the bottom of the chip discharging port. The chip discharging chains are installed on the frame. A support frame is installed at the tail of the chip discharging chain, and a blanking head intercepting net is installed on the support frame. The blanking head intercepting net is arranged with one end high and one end low. A debris box is independently arranged below the high end of the blanking head intercepting net, and a blanking head box is independently arranged below the low end of the blanking head intercepting net.

[0023] In a more optimized solution, the chip discharging chain includes a number of connected single chains.

The inner concave body and the outer convex body are connected through a connecting shaft. Two vertical side bodies are installed at the top of the single chain. The vertical side bodies are located on both sides of the scrap curtain.

[0024] In a more optimized solution, a chip cleaning mounting plate is distributed inside the end of the chip discharging chain. An air pressure nozzle is installed on the chip cleaning mounting plate. The air pressure nozzle is arranged towards the single chain for cleaning the debris in the gaps between the single chains.

[0025] A processing method for a casting blank processing device of compressor parts is as follows:

[0026] Step 1, casting loading

[0027] Clamp the casting on the casting clamping assembly for fixation, drive the rotating table to rotate 180° through the rotating motor, and the clamped casting is located below the sawing assembly;

[0028] Step 2, blanking head sawing

[0029] The longitudinal motor drives the longitudinal slide table to approach the rotating table along the longitudinal slide rail, the rotary frame approaches the casting, and the casting clamping assembly and the rotary frame form a transmission fit;

[0030] The servo motor drives the vertical lead screw to rotate, the vertical slide table moves vertically downward along the vertical lead screw and the vertical slide rail, the sawing cover is arranged outside the casting clamping assembly, the clamping piece clamps the material head of the casting, and the rotary motor drives the rotary frame and the casting to rotate simultaneously;

[0031] The sawing motor installed on the vertical slide table drives the sawing blade to rotate and saw the material head. During sawing, the lubricating oil nozzle cools and lubricates the sawing blade;

[0032] While sawing, another group of castings is clamped on the corresponding casting clamping assembly;

[0033] Step 3, lubricating oil separation

[0034] The air pump conveys high-pressure air to the connecting pipe. The high-pressure air is discharged through the air supply port and conveys the debris along the material receiving slope to the filtering slope. When the debris passes through the filtering slope, the filtering motor drives the cam disc to move the connecting plate and the filter net up and down reciprocally, throwing the debris upward multiple times. Each time the debris is thrown upward, the high-pressure air nozzle on the inclined plate blows the debris downward, separating the lubricating oil on the surface and dropping it into the recycling box through the filter net;

[0035] Step 4, sorting and discharging chips

[0036] The debris falls onto the chip discharging chain through the chip discharging port. The debris is distributed on the chip discharging chain through the material blocking curtain and is scattered on the material head intercepting net at the end. The debris passes through the material head intercepting net and drops into the debris box, and the material head is intercepted by the material head intercepting net and drops into the material head box;

[0037] At the end, the air pressure nozzle blows and cleans the debris towards the gap of the single chain, and the debris will not enter the gap of the single chain.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The present invention drives the rotary table to rotate through the rotary motor, reverses the positions of the front and rear two groups of casting clamping assemblies, and cooperates with the up and down movement of the sawing blade to complete the working mode of clamping and sawing one casting at a time, improving the processing efficiency of the casting material head.

[0040] 2. The present invention drives a rotating member to perform a rotating motion through a rotating motor. The clamping member is used to clamp the stock head and cooperate with the rotating member to perform a rotating motion, ensuring that the position of the stock head remains at a certain position during sawing, thereby ensuring the sawing quality. After repeated research, the inventor found that the positions, shapes, and sizes of the stock heads of each casting are different. Therefore, it is impossible to effectively ensure the position of the stock head during each clamping. Since most compressor castings are made of aluminum, when sawing, especially at the end position of sawing, problems with the quality of the stock head will occur. The inventor uses the pressure columns on the inner pressure sleeve and the outer pressure sleeve to clamp and fix the stock head under the action of a pressure medium, thereby ensuring the stable position of the stock head during sawing. The inventor drives the longitudinal slide to move through the longitudinal motor, and ensures that the clamping member can clamp the stock head through the transverse movement of the rotating member. After sawing, the elastic ejector post can eject the sawed stock head outward to complete the automatic ejection of the stock head.

[0041] 3. The present invention provides a concave opening on the inner side of the top of the aggregate box. A high-pressure gas is input into the connecting pipe through an air pump in the concave opening. The high-pressure gas conveys the debris to the filtering slope through the air supply port. By making the slope of the material receiving slope greater than that of the filtering slope, it is convenient and efficient to recycle the lubricating oil. The filtering motor drives the cam disc to rotate, driving the filter screen and the connecting plate to move up and down reciprocally, causing the debris to be thrown upward reciprocally multiple times. After being thrown upward and cooperating with the blowing of the high-pressure air nozzle, it can ensure the efficient recycling of the lubricating oil.

[0042] 4. The present invention installs a material blocking curtain at the bottom of the aggregate box to prevent debris from falling off the chip removal chain. The air pressure nozzle at the end can blow and clean the debris in the gaps of the single chain. The chip removal chain separates the debris and the stock head through the stock head intercepting net at the end. The debris enters the debris box, and the stock head enters the stock head box through the stock head intercepting net to complete the sorting, discharging, and recycling operation of the debris and the stock head.

[0059] Embodiment 1

[0060] As Figure 1 、 Figure 4 、 Figure 9 shown, a casting blank processing device for compressor parts includes:

[0061] A frame 10, on which a rotating motor 11 is installed;

[0062] A rotating table 20, which is rotatably installed on the frame 10. Two sets of symmetrically distributed casting clamping assemblies 12 are installed on the rotating table 20. The output end of the rotating motor 11 is installed on the bottom surface of the rotating table 20;

[0063] A sawing component, which includes a beam frame 30 installed on the frame 10. A vertical slide rail 31, a motor base 32 and a servo motor 33 are installed on the beam frame 30. A vertical slide table 34 is slidably matched on the vertical slide rail 31. The servo motor 33 is installed on the motor base 32. The output end of the servo motor 33 is connected to a vertical lead screw 35. The vertical lead screw 35 is rotatably installed on the beam frame 30. The vertical slide table 34 is slidably matched on the vertical lead screw 35. A sawing cover 36 and a sawing motor 37 are installed on the vertical slide table 34. The output end of the sawing motor 37 is installed with a sawing blade 38;

[0064] An aggregate box 40, which is installed on the frame 10 and is located below the sawing component. A filter screen 41 is arranged on the material receiving side of the aggregate box 40. A recycling box 42 is independently arranged below the filter screen 41.

[0065] Clamp the casting on the casting clamping assembly 12. The rotating motor 11 drives the rotating table 20 to rotate horizontally by 180°, so that the casting is located below the sawing blade 38. The servo motor 33 drives the vertical slide table 34 to move downward along the vertical slide rail 31 through the rotation of the vertical lead screw 35. The sawing cover 36 covers the outside of the casting clamping assembly 12 and the casting. The sawing motor 37 drives the sawing blade 38 to rotate to complete the sawing operation of the stock head.

[0066] Example 2

[0067] In Example 1, during specific implementation, since the casting is clamped and the stock head lacks support, during the process of sawing off the end segment, the stock head is prone to deviation, affecting the sawing surface quality of the casting stock head. Therefore, a longitudinal slide rail 13 and a longitudinal motor 14 are installed on the frame 10, as Figures 1 to 8 shown. A longitudinal lead screw 15 is installed at the output end of the longitudinal motor 14. The longitudinal lead screw 15 is rotatably installed on the frame 10. A longitudinal slide table 16 is matched with the longitudinal lead screw 15. A rotary frame 17 and a rotary motor 21 for driving the rotary frame 17 to perform a rotary motion are rotatably installed on the longitudinal slide table 16. The rotary frame 17 is of a cylindrical structure and a clamping member 18 is arranged inside. The clamping member 18 is used for clamping the stock head;

[0068] The casting clamping assembly 12 is rotatably installed on the rotating table 20. The casting clamping assembly 12 is a three-jaw pneumatic chuck. A first follower is fitted on the outside of the casting clamping assembly 12. A second follower is installed on the outside of the rotary frame 17. The first follower and the second follower are selectively adapted to form a transmission cooperation between the casting clamping assembly 12 and the rotary frame 17. The first follower and the casting clamping assembly 12 form a transmission cooperation. The second follower and the rotary frame 17 form a transmission cooperation. A female head is arranged on the first follower, and a male head adapted to be inserted and mated with the female head is arranged on the second follower. The axis of the casting clamping assembly 12 coincides with the axes of the longitudinal motor 14 and the rotary frame 17.

[0069] The longitudinal motor 14 drives the longitudinal lead screw 15 to rotate. The longitudinal slide table 16 moves linearly along the longitudinal slide rail 13 and approaches the stock head of the casting. The first follower and the second follower complete the transmission cooperation. The clamping member 18 clamps the stock head. Subsequently, the rotary motor 21 drives the rotary frame 17 and the casting clamping assembly 12 to perform a rotary motion. The rotary motor 21 drives the casting and the casting clamping assembly 12 to rotate, and then cooperates with the high-speed rotating sawing blade 38 above to complete the sawing of the stock head at a high speed.

[0070] The clamping member 18 includes a first clamping part and a second clamping part arranged in the cylindrical structure. The first clamping part and the second clamping part clamp the stock head from the inside and the outside respectively;

[0071] The first clamping part includes an inner pressure sleeve 181. The inside of the inner pressure sleeve 181 is a hollow structure. Step holes one are uniformly arranged on the side of the inner pressure sleeve 181. Springs sleeved outside the inner pressure column 183 are installed in the step holes one. The inner pressure column 183 is slidably fitted in the step holes one;

[0072] The second clamping part includes an outer pressure sleeve 182. The inside of the outer pressure sleeve 182 is a hollow structure. Step holes two are uniformly arranged on the side of the outer pressure sleeve 182. Springs sleeved outside the outer pressure column 184 are installed in the step holes two. The outer pressure column 184 is slidably fitted in the step holes two;

[0073] Both the inner pressure column 183 and the outer pressure column 184 are arranged perpendicular to the sprue. The outer pressure sleeve 182 and the inner pressure sleeve 181 are interconnected. A rotating ring 185 is rotatably installed on the outer side of the rotating frame 17. A pressure medium inlet and a pressure medium outlet are installed on the rotating ring 185. The pressure medium inlet and the pressure medium outlet are connected to a solenoid valve 186 through pipelines. The solenoid valve 186 is connected to a medium pump 187 through pipeline one and to a filter 189 through pipeline two. The medium pump 187 is installed in the medium tank 188.

[0074] By controlling the solenoid valve 186 through the control system, during the operation of clamping the sprue, after the pressure medium enters the outer pressure sleeve 182 and the inner pressure sleeve 181, the inner pressure column 183 and the outer pressure column 184 are externally pushed by the medium pressure until the pressure value inside the outer pressure sleeve 182 and the inner pressure sleeve 181 reaches a set constant value. Then, the sprue is clamped and fixed. The rotary motor 21 drives the casting to rotate, and cooperates with the high-speed rotating saw blade 38 descending from above to complete high-quality sawing operation. Through the radial clamping operation of the pressure columns, the deviation caused by the side gap when the sprue enters the rotating frame 17 axially is avoided, and thus the problem of the lower side cutting edge of the sawing surface caused by the drooping of the sprue due to the gravity at the end of sawing is eliminated. The conventional sawing method is in a single sawing direction, and the circumferential sawing method adopted in this embodiment can ensure that the quality of the sawing surface will not have a cutting edge.

[0075] Embodiment 3

[0076] In Embodiment 2, the clamping member 18 further includes an elastic ejector post 19. The elastic ejector posts 19 are distributed at the inner end of the rotating frame 17 between the inner pressure column 183 and the outer pressure column 184. The elastic ejector post 19 includes a fixed sleeve 191 and an ejector post body 192. A spring is installed in the fixed sleeve 191. The ejector post body 192 is slidably fitted in the fixed sleeve 191 and its end face abuts against the spring. Through the elastic ejector post 19, it can be ensured that after the sprue is sawn, when the longitudinal motor 14 drives the longitudinal slide 16 to reset, the sprue actively disengages from the rotating frame 17.

[0077] Embodiment 4

[0078] In Embodiment 3, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, the aggregate box 40 is located in the area below the sawing assembly, which is the material receiving side. An inner concave opening 43 is provided at the top of the material receiving side. An air pump 44 and a connecting pipe 45 are installed in the inner concave opening 43. A number of air supply ports 46 are evenly distributed on the outer wall of the connecting pipe 45. The air supply ports 46 are used to convey the debris along the material receiving side to the bottom of the aggregate box 40. The sawed debris falls on the material receiving side. For the debris on the material receiving side, under the action of the high-pressure gas conveyed by the air pump 44 into the connecting pipe 45, the high-pressure gas conveys the debris to the filtering slope 402 through the air supply ports 46.

[0079] The material receiving side is successively distributed with a material receiving slope 401, a filtering slope 402, and a blanking slope 403 from top to bottom. The inclination angle of the filtering slope 402 is smaller than that of the material receiving slope 401, so that the debris first completes the primary separation when entering the filtering slope 402. A recovery box 42 is independently provided below the filtering slope 402. An opening and a guiding frame 404 located below the opening are provided on the filtering slope 402. A filter net 41 is slidably fitted in the opening and the guiding frame 404. A lower spring member 411406 is installed on the aggregate box 40. A filtering motor 405 is installed on the lower spring member 411406. The output end of the filtering motor 405 is fixedly installed with a cam disc 407. A connecting plate 408 is attached below the cam disc 407. The connecting plate 408 is connected to the filter net 41 through a connecting column. Two groups of guiding columns 409 are inserted through the connecting plate 408. The two groups of guiding columns 409 are fixed on the guiding frame 404 and the aggregate box. Spring members 410 are distributed outside the guiding columns 409. The spring members 410 are located below the connecting plate 408. When the debris enters the filtering slope 402, the filtering motor 405 drives the cam disc 407 to reciprocate up and down, thereby throwing the debris upward multiple times. Cooperating with the high-pressure air nozzles 412 on the inclined plate 411 to blow the debris. After throwing the debris upward for 0.2 - 1.0 s, when the debris has a certain initial velocity close to the inclined plate 405, the high-pressure air nozzles 412 blow the debris, and the separation of the lubricating oil is efficiently completed.

[0080] An inclined plate 411 is installed inside the aggregate box 40. A number of high-pressure air nozzles 412 are evenly distributed on the inclined plate 411. The high-pressure air nozzles 412 are arranged towards the filtering slope 402.

[0081] Example 5

[0082] In Example 4, as Figure 10As shown, a chip discharge port 413 is provided at the bottom of the aggregate bin 40. A chip discharge chain 414 is installed below the chip discharge port 413. Baffle curtains 415 are provided on both sides of the chip discharge port 413 facing the running direction of the chip discharge chain 414 and parallel to the running direction of the chip discharge chain 414. The bottom of the chip discharge port 413 is distributed with the chip discharge chain 414. The chip discharge chain 414 is installed on the frame 10. A support frame 416 is installed at the tail of the chip discharge chain 414. A blanking head interception net 417 is installed on the support frame 416. The blanking head interception net 417 is arranged with one end high and one end low. A debris box 418 is independently arranged below the high end of the blanking head interception net 417. A blanking head box 419 is independently arranged below the low end of the blanking head interception net 417.

[0083] The chip discharge chain 414 includes a number of connected single chains 4140. An outer convex body 4141 is provided at one end of the single chain 4140, and an inner concave body 4142 is provided at the other end. The inner concave body 4142 and the outer convex body 4141 are connected by a connecting shaft. Two vertical side bodies 4143 are installed at the top of the single chain 4140. The vertical side bodies 4143 are located on both sides of the baffle curtain 415.

[0084] A chip cleaning mounting plate 420 is distributed inside the end of the chip discharge chain 414. An air pressure nozzle 421 is installed on the chip cleaning mounting plate 420. The air pressure nozzle 421 is arranged facing the single chain 4140 for cleaning the debris in the gaps of the single chain 4140.

[0085] The debris is discharged outside through the chip discharge port 413 onto the chip discharge chain 414. The chip discharge chain 414 conveys the debris to the end, and the debris is scattered onto the blanking head interception net 417 at the end. The blanking head is intercepted by the blanking head interception net 417 and introduced into the blanking head box 419. The debris passes through the blanking head interception net 417 and is introduced into the debris box 418.

[0086] Embodiment 6

[0087] As Figures 1 to 13 shown, a processing method of a compressor part casting processing device is as follows:

[0088] Step 1, casting loading

[0089] The casting is clamped and fixed by the casting clamping assembly 12. The rotating table 20 is driven by the rotating motor 11 to rotate 180°. The clamped casting is located below the sawing assembly;

[0090] Step 2, blanking head sawing

[0091] The longitudinal motor 14 drives the longitudinal sliding table 16 to approach the rotating table 20 along the longitudinal slide rail 13. The rotary frame 17 approaches the casting. The casting clamping assembly 12 and the rotary frame 17 form a transmission cooperation;

[0092] The servo motor 33 drives the vertical lead screw to rotate. The vertical slide 34 moves vertically downward along the vertical lead screw and the vertical slide rail 31. The sawing cover 36 covers the outside of the casting clamping assembly 12. The clamping member 18 clamps the stock head of the casting. The rotary motor 21 drives the rotary frame 17 and the casting to rotate simultaneously;

[0093] The sawing motor 37 installed on the vertical slide 34 drives the sawing blade 38 to rotate and saw the stock head. During sawing, the lubricating oil nozzle cools and lubricates the sawing blade 38;

[0094] While sawing, another set of castings is clamped on the corresponding casting clamping assembly 12;

[0095] Step 3, lubricating oil separation

[0096] The air pump 44 conveys high-pressure air to the connecting pipe 45. The high-pressure air is discharged through the air supply port 46 and conveys the debris along the material receiving slope 401 to the filtering slope 402. When the debris passes through the filtering slope 402, the filtering motor 405 drives the cam disc 407 to move the connecting plate 408 and the filter net 41 up and down reciprocally, throwing the debris upward multiple times. Each time when throwing upward, the high-pressure air nozzles 412 on the inclined plate 411 blow the debris downward, separating the lubricating oil on the surface and dropping it into the recovery box 42 through the filter net 41;

[0097] Step 4, sorting and chip removal

[0098] The debris falls on the chip removal chain 414 through the chip removal port 413. The debris is distributed on the chip removal chain 414 through the baffle curtain 415 and is scattered on the stock head interception net 417 at the end. The debris passes through the stock head interception net 417 and drops into the debris box 418, and the stock head is intercepted by the stock head interception net 417 and drops into the stock head box 419;

[0099] At the end, the debris is blown and cleaned through the air nozzles towards the gap of the single chain 4140, and the debris will not enter the gap of the single chain 4140.
