Description

Technical Field

[0001] The present invention relates to the field of grinding, and more specifically, to a processing device for a compressor base. Background Art

[0002] When processing the base, one surface needs to be ground, and the precision requirement for grinding this surface is extremely high. In the prior art, grinding is mainly carried out by using a grinding roll to contact the surface to be processed. Specifically, the grinding roll rotates self - sufficiently, and the end face of the grinding roll contacts the surface to be processed, so as to grind the surface to be processed.

[0003] However, since waste chips are generated during grinding and the waste chips will stay on the surface to be processed. In the prior art, the waste chips are mainly blown away. However, the freshly ground waste chips are magnetic, so some waste chips will stick to the surface to be processed and are difficult to be blown away. There are also some technologies that suck away the waste chips. However, since the positions where the waste chips exist are relatively wide and the suction range is limited, it is difficult to suck away the waste chips only by suction. Therefore, the waste chips are very likely to reach between the end face of the grinding roll and the surface to be processed. Then the grinding roll will squeeze the waste chips, and then the waste chips will squeeze the surface to be processed, resulting in wear of the surface to be processed and greatly reducing the precision requirement of the grinding process. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a processing device for a compressor base, which can gather a large range of waste chips into a small range by driving an external force, and then suck away the waste chips in the small range, so as to better ensure the cleaning effect of the waste chips, avoid the waste chips from adhering to the surface to be processed, and greatly improve the quality of the grinding process.

[0008] Further, a transmission member is provided at the suction pipe, and the transmission member is used to constitute a transmission between the cleaning rod and the suction pipe, so that when the cleaning rod is in the third displacement position, the multiple cleaning rods approach each other and form a small conical state, and when the cleaning rod is in the first displacement position, the multiple cleaning rods move away from each other and form a large conical state; and when the cleaning rod moves down from the first displacement position to the second displacement position, the multiple cleaning rods all form a large conical state.

[0009] Further, when the cleaning rod is in the second displacement position and the third displacement position, the cleaning portion contacts the workpiece.

[0010] Further, a control member is provided at the suction pipe, and the control member is used to be connected to the suction pipe and drive the suction pipe to move to a first material suction position and a second material suction position; when the cleaning rod is in the third displacement position, the suction pipe is in the second material suction position; when the cleaning rod is in the first displacement position and the second displacement position, the suction pipe is in the first material suction position; the second material suction position is below the first material suction position.

[0011] Further, a flared cylinder is formed at one end of the suction pipe close to the cleaning rod.

[0012] Further, the cleaning rod is a soft rod made of rubber material with elastic deformation.

[0013] Further, a plurality of arc grooves are formed on the end surface of the grinding knife for grinding the machine base, and the plurality of arc grooves are circumferentially arrayed with the axis of the grinding knife as the center of the circle.

[0036] Processing device for compressor base, used to process the base of a compressor. One surface of the compressor base is polished to make it smooth. The processing device includes: a grinding machine tool, which consists of a grinding device, a drive system, and a fixture. The fixture is used to clamp the workpiece to be processed, and the drive system is used to drive the grinding device to move in three dimensions to process the workpiece to be processed. The grinding device includes: a mounting block 1, a grinding tool 2, a rotary drive member, and a cleaning assembly 3. The rotary drive member is arranged in the mounting block 1 and is connected to the grinding tool 2. The rotary drive member is used to drive the grinding tool 2 to rotate. There are nine grinding tools 2, and the nine grinding tools 2 are arrayed in three groups along the first dimension and three groups along the second dimension. The first dimension is perpendicular to the second dimension. The rotary drive member includes a first drive motor 5 and a second drive motor 6. There is one first drive motor 5, and the first drive motor 5 is connected to the middle grinding tool 2. The first drive motor 5 is used to drive the middle grinding tool 2 to rotate on its own axis. There are eight second drive motors 6, and the eight second drive motors 6 are respectively connected to eight grinding tools 2 to make the eight grinding tools rotate. The rotation of the grinding tool 2 can polish the flat surface on the workpiece. Any four grinding tools 2 enclose a receiving area, and the receiving area is used to receive the waste material ground off by the grinding tool 2. There are four cleaning assemblies 3, and each cleaning assembly 3 is separately located in a receiving area. The cleaning assembly 3 is used to absorb the waste material in the receiving area.

[0037] Specifically, the cleaning assembly 3 includes: a cleaning rod 31, a displacement driving member, and an air suction pipe 32. The displacement driving member is an electric push rod. A plurality of cleaning rods 31 are provided for cleaning waste materials. A connecting seat 311 is provided at the cleaning rod 31. The connecting seat 311 is used to mount a plurality of cleaning rods 31, so that the plurality of cleaning rods 31 and the connecting seat 311 form an integral body that moves synchronously. The plurality of cleaning rods 31 are distributed along the edge of the connecting seat 311, so that there is no cleaning rod 31 in the middle of the connecting seat 311. A circular hole is opened in the middle of the connecting seat 311, and the air suction pipe 32 is inserted into the circular hole. A cleaning area is formed between the plurality of cleaning rods 31. One end of the air suction pipe 32 is located below the connecting seat 311 and between the plurality of cleaning rods 31. The other end of the air suction pipe 32 is located above the mounting block 1. The other end of the air suction pipe 32 is in contact with the air pump, so that the air suction pipe 32 will continuously suck dust. The displacement driving member is used to raise and lower the connecting seat 311. Thus, the connecting seat 311 will drive the cleaning rod 31 to rise and fall. Then, when the cleaning rod 31 descends until it contacts the surface of the workpiece, the cleaning area will wrap the accommodating area, and most of the waste materials in the accommodating area will be located in the cleaning area. Then, the air suction pipe 32 absorbs the waste materials in the cleaning area. Then, the cleaning rod 31 rises, so that the cleaning rod 31 is away from the surface of the workpiece, and the cleaning area does not wrap the accommodating area. At this time, the grinding knife 2 grinds the workpiece, and the newly generated waste materials from the grinding will reach the accommodating area again. Then, the cleaning rod 31 moves down again, and repeatedly moves the cleaning rod 31 up and down to clean the waste materials in the accommodating area. Thus, to a certain extent, the accumulation of waste materials on the surface of the workpiece can be reduced, and the grinding quality of the workpiece is better. Exactly speaking, a cleaning portion is formed at the end of the cleaning rod, and the cleaning area is surrounded by the cleaning portions of the plurality of cleaning rods. Then, the cleaning area is a three-dimensional space area.

[0038] More specifically, the cleaning rod 31 is made of a soft material. A root portion 312 is provided at the end of the cleaning rod 31 close to the connecting seat 311. The root portion 312 is made of a hard material, so that the cleaning rod 31 can rotate or bend around the root portion 312. A transmission member and a control member are provided at the air suction pipe. The cleaning assembly 3 further includes: a sliding member 33, a fixing block 34, a power member 35, a fixing plate 36, a clamping member 37, and a first spring 38. The power member 35 includes: a push rod 351, a push plate 352, a connecting rod 353, a connecting plate 354, and a clamping convex block 355. A second spring 361 and a limiting ring 362 are provided below the fixing plate 36. The clamping member 37 includes a first triangular clamping block 371, a second triangular clamping block 372, a guiding rod 373, a third spring 374, and a pulling rope 375. A guiding portion 322 is formed on the air suction pipe 32.

[0039] The guiding part 322 is an annular protrusion. The cross-section of the guiding part 322 is arc-shaped. The guiding part 322 is integrally formed and fixed with the suction pipe 32. When the connecting seat 311 drives the cleaning rod 31 to move downward until the cleaning rod 31 contacts the guiding part 322, the connecting seat 311 will continue to drive the cleaning rod 31 to move downward. Then, the guiding part 322 will guide the cleaning rod 31, forcing the cleaning rod 31 to turn outward relative to the root part 312. As a result, multiple cleaning rods 31 will expand outward to form a large cone, greatly increasing the area of the cleaning area formed by the multiple cleaning rods 31. There will be a part of the root part 312 that can contact the guiding part 322, that is, when the connecting seat 311 moves downward, the root part 312 contacts the guiding part 322. Then, the cleaning rod 31 can be turned outward relative to the root part 312, and the root part 312 can also push the guiding part 322 to move downward, thereby causing the suction pipe 32 to move downward. The sliding part 33 is fixedly connected to the suction pipe 32.

[0040] The displacement driving part is used to drive the connecting plate 354 to rise and fall. The connecting rod 353 is fixedly connected to the connecting plate 354, the pushing plate 352 is fixedly connected to the connecting rod 353, the pushing rod 351 is fixedly connected to the pushing plate 352, the clamping convex block 355 is integrally formed with the pushing rod 351, and the clamping convex block 355 protrudes outward relative to the pushing rod 351 to form a pushing plane. The pushing rod 351, the pushing plate 352, the connecting rod 353, the connecting plate 354, and the clamping convex block 355 move synchronously.

[0041] The fixed block 34 is fixed relative to the mounting block 1. The fixed block 34 is a tubular structure. The sliding member 33 is located inside the fixed block 34 and the sliding member 33 is in sliding fit with the inner wall of the fixed block 34. A cavity is formed in the sliding member 33, and the suction pipe 32 is located in the cavity. The connecting seat 311 is located in the cavity, and the connecting seat 311 is in sliding fit with the inner wall of the cavity. The push rod 351 contacts the connecting seat 311. A through groove is formed in the sliding member 33, and the push rod 351 is inserted into the through groove and the push rod 351 is in sliding fit with the through groove. The pushing plane is located outside the through groove, that is, when the push rod 351 moves downward, the sliding member 33 will be driven to move downward through the pushing plane. The fixing plate 36 is fixedly connected to the inner wall of the fixed block 34 and the fixing plate 36 is located above the sliding member 33. The second spring 361 has two ends. One end of the second spring 361 is fixedly connected to the fixing plate 36, and the other end of the second spring 361 is fixedly connected to the sliding member 33. The second spring 361 is used to pull the sliding member 33 to receive an upward movement force. The limiting ring 362 is fixedly connected to the inner wall of the sliding member 33. The limiting ring 362 is used to contact the sliding member 33 when the sliding member 33 moves upward to limit the upward movement position of the sliding member 33 so that the sliding member 33 can only be located below the limiting ring 362. A pull plate is formed at one end of the suction pipe 32 away from the guiding portion 322. The pull plate is fixedly connected to the suction pipe 32. The first spring 38 has two ends. One end of the first spring 38 is fixedly connected to the pull plate, and the other end is fixed relative to the mounting block 1. Thus, the first spring 38 is used to make the pull plate receive an upward movement force, that is, the suction pipe 32 will receive an upward movement force.

[0042] The second triangular clamping block 372 is fixedly connected to the side surface of the sliding member 33. A sliding groove is formed at the edge of the fixing block 34. The guiding rod 373 is inserted into the sliding groove. Part of the guiding rod 373 is located inside the fixing block 34, and part is located outside the fixing block 34. The guiding rod 373 is slidably connected to the sliding groove. The first triangular clamping block 371 is fixedly connected to the guiding rod 373. The first triangular clamping block 371 is located inside the fixing block 34. A first limiting surface and a first guiding surface are formed on the first triangular clamping block 371. A second limiting surface and a second guiding surface are formed on the guiding rod 373. The pull rope 375 has two ends. One end of the pull rope 375 is fixedly connected to the guiding rod 373, and the other end is fixedly connected to the push plate 352. The third spring 374 is located between the inner wall surface of the fixing block 34 and the guiding rod 373. When the push plate 352 moves upward, it will pull the pull rope 375, and then the pull rope 375 will pull the second triangular clamping block 372 to move closer to the inner wall surface of the fixing block 34. When the push plate 352 moves downward, the fixing plate 36 electric push rod 4 will apply an elastic force to the second triangular clamping block 372 to move the arc surface 23 of the cleaning assembly 3 away from the inner wall surface of the fixing block 34. When the first limiting surface contacts the second limiting surface, the second triangular clamping block 372 will position the first triangular clamping block 371, making the first triangular clamping block 371 located below the second triangular clamping block 372, thereby also restricting the position of the sliding member 33 and preventing the sliding member 33 from moving upward under the pulling of the second spring 361.

[0043] Specifically, the mounting block 1 includes: a top plate 11, side plates 12, a bottom plate 13, and a partition plate 14. The power member 35 includes an electric push rod 4 and a support plate 7. The top plate 11, side plates 12, and bottom plate 13 are all fixedly connected to each other. The top plate 11, side plates 12, and bottom plate 13 form a rectangular block structure. The top plate 11, side plates 12, and bottom plate 13 enclose an installation chamber. The partition plate 14 is located in the installation chamber and is fixedly connected to the inner wall of the installation chamber. The electric push rod 4 is fixedly installed on the partition plate 14. The support plate 7 is connected to the output end of the electric push rod 4. The electric push rod 4 is used to drive the support plate 7 to move upward and downward. The connecting plate 354 is fixedly connected to the support plate 7. Since there are multiple cleaning assemblies 3, the connecting plates 354 in the multiple cleaning assemblies 3 are all fixedly connected to the support plate 7. When the support plate 7 moves upward and downward, it will simultaneously drive the connecting plates 354 in the multiple cleaning assemblies 3 to move upward and downward together.

[0044] Specifically, a clamping ring is formed on the inner wall of the sliding member 33. The clamping ring is fixedly connected to the sliding member 33. At least part of the clamping ring faces the connecting seat 311. Then, when the sliding member 33 moves upward, it will pull the connecting seat 311 upward through the clamping ring.

[0045] The control member is the first spring 38 and the part for moving the suction pipe 32 upward. The transmission member is the part for closing or spreading 31.

[0046] In some embodiments, 31 is a soft material and 31 cannot rebound on its own. Then, when 32 and 33 move downward, 33 will press on 31, causing 31 to be located inside 33 and bringing multiple 31s closer to each other.

[0047] In some embodiments, the first driving motor 5 and the second driving motor 6 are indirectly connected to the grinding tool 2. Specifically, the first driving motor 5 is indirectly connected to the grinding tool 2 through a belt drive structure 8, and the second driving motor 6 is indirectly connected to the grinding tool 2 through the belt drive structure 8. The belt drive structure 8 is a prior art, so it can be known that the first driving motor 5 is located at a position far from the middle grinding tool 2. Similarly, the second driving motor 6 is located at a position far from the edge grinding tool 2. Then, no parts are provided above all the grinding tools 2. At this time, an embedding chamber penetrating the grinding tool 2 is opened in the middle of the grinding tool 2. A set of cleaning components 3 is installed in the embedding chamber. Thus, the middle of the grinding tool 2 is empty, and the edge of the grinding tool 2 is solid. The edge of the grinding tool 2 grinds the surface of the workpiece. When the edge of the grinding tool 2 grinds the surface of the workpiece, some waste materials will reach the outside of the grinding tool 2, and some waste materials will also reach the middle of the grinding tool 2. In this way, the waste materials at the grinding tool 2 can be quickly discharged outwards, and then the cleaning components 3 in the accommodating area suck away the waste materials in the accommodating area, and the waste materials in the middle of the grinding tool 2 are sucked away by the cleaning components 3 in the middle of the grinding tool 2, so that the speed of sucking away the waste materials can be greatly increased.

[0048] In some embodiments, a plurality of arc grooves 22 and a circular groove 21 are formed on the end face of the grinding tool 2 close to the workpiece. The circular groove 21 is located in the middle of the grinding tool 2, and the arc grooves 22 are located at the edge of the grinding tool 2. And the plurality of arc grooves 22 are all communicated with the circular groove 21 to form a discharge channel for discharging waste materials outwards to the accommodating area. An arc surface 23 is formed on the grinding tool 2.

[0049] Working principle:

[0050] During use, first, the fixture clamps the workpiece, and then the drive system drives the mounting block 1 to move, causing the mounting block 1 to move to a specified position to grind the workpiece.

[0051] The grinding tool 2 will contact the workpiece to be ground. Then, the first driving motor 5 and the second driving motor 6 will cause multiple grinding tools 2 to rotate, so that the grinding tool 2 grinds the workpiece. The discharge channel on the grinding tool 2 is used to accommodate the waste materials generated during grinding, preventing some waste materials from being squeezed between the grinding tool 2 and the workpiece, thus avoiding the phenomenon that the grinding tool 2 cannot grind the workpiece well. Then, the grinding tool 2 rotates, and the waste materials can be discharged to the accommodating area outside the discharge channel by the inertial force generated by the rotation, so that the waste materials can continuously reach the accommodating area, and the waste materials will not affect the grinding.

[0052] The electric push rod 4 will drive the support plate 7 to move up and down reciprocally. The starting position of the cleaning rod 31 is far from the workpiece, and the starting position of the suction pipe 32 is also far from the workpiece. When the support plate 7 moves downward, the support plate 7 drives the connecting plate 354 to move downward, so that the connecting plate 354, the connecting rod 353, the push plate 352, the push rod 351 and the clamping bump 355 move downward simultaneously. The push rod 351 pushes the connecting seat 311 to move downward, and then the connecting seat 311 drives the cleaning rod 31 to move downward. Multiple cleaning rods 31 will contact the guiding part 322, and then the guiding part 322 causes the cleaning rod 31 to turn outwards. Multiple cleaning rods 31 form a large cone, and then multiple cleaning rods 31 will contact the upper surface of the workpiece in the accommodating area. At this time, the cleaning rod 31 is located at the second displacement position, and at this time the suction pipe 2 is located at the first material suction position. Then the push rod 351 continues to move downward, and the clamping bump 355 on the push rod 351 will contact the sliding part 33, and then the clamping bump 355 drives the sliding part 33 to move downward. The sliding part 33 drives the suction pipe 32 to move downward. The downward movement of the suction pipe 32 will cause the guiding part 322 to move downward, and the guiding part 322 moves away from the root 312, so that the cleaning rod 31 changes from the state of turning outwards to form a large cone to the state of contracting inwards to form a small cone. Thus, multiple cleaning rods 31 will gather the waste on the accommodating area, so that the waste will be gathered in the middle of multiple cleaning rods 31, that is, the position where the suction pipe 32 is located. Then the suction pipe 32 can directly suck away the waste, and the downward movement of the suction pipe 32 will also make the suction pipe 32 closer to the waste, which is better for the suction pipe 32 to suck away the waste. At this time, the sweeping rod 31 is located at the third displacement position, and the suction pipe 2 is located at the second material suction position.

[0053] Then when the sliding part 33 moves downward, the first triangular clamping block 371 on the sliding part 33 moves downward together. Then the first triangular clamping block 371 moves to the second triangular clamping block 372. The first guiding surface contacts the second guiding surface, which will force the second triangular clamping block 372 to move close to the inner wall of the fixed block 34. Then the first triangular clamping block 371 moves to the lower part of the second triangular clamping block 372, and then the second triangular clamping block 372 resets. At this time, if the sliding part 33 moves upward, it will be clamped under the action of the first triangular clamping block 371 and the second triangular clamping block 372.

[0054] Then the support plate 7 moves upward. The support plate 7 drives the connecting plate 354 to move upward, so that the push rod 351 also moves upward. Then the push rod 351 drives the connecting seat 311 to move upward. Then the clamping bump 355 moves upward and no longer abuts against the sliding part 33. At this time, the sliding part 33 should originally move upward under the action of the second spring 361. However, since the first limiting surface of the first triangular clamping block 371 and the second limiting surface of the second triangular clamping block 372 limit the upward movement of the first triangular clamping block 371, the sliding part 33 cannot move upward together with the connecting seat 311. That is, the suction pipe 32 cannot move upward together with the connecting seat 311. That is, the guiding part 322 cannot move upward together with the cleaning rod 31. Then during the upward movement of the cleaning rod 31, the suction pipe 32 will not contact the cleaning rod 31. Thus, the cleaning rod 31 will always maintain a small conical state. Then at this time, it is possible to avoid the situation where the cleaning rod 31 changes from a small conical shape to a large conical shape when the cleaning rod 31 and the guiding part 322 move upward at the same time, resulting in the waste at the edge of the accommodating area being swept outward. Thus, it better ensures that the waste in the accommodating area is located in the accommodating area and will not spread outward to the position of the grinding tool 2.

[0055] After the push rod 351 moves upward to a certain position, the push plate 352 will pull the pull rope 375 to move. The pull rope 375 will pull the second triangular clamping block 372 to move close to the inner wall surface of the fixed block 34. Then at this time, the first spring 38 pulls the suction pipe 32 to move upward. Thus, the suction pipe 32 will move upward for reset. Since the sliding part 33 and the suction pipe 32 move together, the sliding part 33 and the suction pipe 32 move upward at the same time. The sliding part 33 stops moving after moving to abut against the limiting ring 362. And at this time, the guiding part 322 on the suction pipe 32 contacts the root part 312, causing the cleaning rod 31 to turn outward again into a large conical state. At this time, the cleaning rod 31 is located at the first displacement position, and the suction pipe 2 is located at the first material suction position.

[0056] The upward and downward movement of the support plate 7 will repeat the above process. Then the cleaning rod 31 will move downward to abut against the workpiece surface where the accommodating area is located in a large conical state, and then the cleaning rod 31 changes to a small conical state to gather the waste at the accommodating area. Then the cleaning rod 31 rises in a small conical state, and then the cleaning rod 31 returns to its original position and changes to a large conical state again.
