Description

Technical Field

[0001] The present invention relates to the technical field of turning, and specifically to a turning device for machining the compressor rear cover with an anti-jumping function. Background Art

[0002] The compressor rear cover is an important part of the compressor, usually used to enclose and protect the internal structure of the compressor to ensure its normal operation. In the design of the compressor rear cover, the sealing performance needs to be considered to prevent gas or liquid leakage. During the production process of the compressor rear cover, in order to ensure its precise fit with other components, turning processing is required to achieve the required dimensions and surface quality. The outer shape and inner hole of the compressor rear cover are precisely machined by turning, so that the assembly between the compressor rear cover and other parts of the compressor is more precise, achieving the required sealing performance. Although turning can machine the required precise dimensions and shapes, the existing turning devices do not have the function of rechecking the accuracy. After the machining is completed, it is still necessary to use other inspection mechanisms after the turning device to detect the flatness of the compressor rear cover. For the positions with machining errors, rework is also required and turning is carried out again. This kind of rechecking method wastes time and reduces the processing efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a turning device for machining the compressor rear cover with an anti-jumping function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A turning device for machining the compressor rear cover with an anti-jumping function, including a machine table, a tool disc and a jumping measuring instrument. A body is installed above the machine table. A number of tool holders for turning workpieces are installed on the tool disc, and tools are installed on the tool holders. A drive box is installed at the input end of the tool disc. The drive box provides power for the tool disc to change tools and for the tools to turn the workpieces (i.e., the compressor rear cover). A moving module is installed below the drive box, and the moving module is installed inside the body. A clamping mechanism for clamping the workpiece, a detection mechanism and a turning mechanism for turning the workpiece are also installed inside the body. The jumping measuring instrument is installed on the detection mechanism. The detection mechanism uses the jumping measuring instrument to detect the flatness of the workpiece after turning. The turning mechanism cooperates with the clamping mechanism to realize the turning of the workpiece, so that the tool can turn each end face of the workpiece. During the turning process, the clamping mechanism adjusts the posture of the workpiece, so that the tool can turn the inner hole, through groove and deep groove on the workpiece. A moving module is installed below the drive box to make the tool process the workpiece or move away from the workpiece. The clamping mechanism fixes the workpiece and adjusts the posture of the workpiece during the turning process, facilitating the tool to process the inner hole, through groove and deep groove on the workpiece. And during the turning process, the turning mechanism and the clamping mechanism cooperate with each other to realize the turning of the workpiece, so that the tool can process different end faces of the workpiece. The turning mechanism and the clamping mechanism cooperate with each other to replace manual labor and realize the automation of the turning process.

[0005] The detection mechanism includes a vertical module and a slide rail slider vertically installed on one side of the machine body. A support plate is jointly installed on the vertical module and the slide rail slider. Slide rails and push-pull cylinders are symmetrically installed on the support plate. The push-pull cylinder is located between the two slide rails. A bottom plate is installed on the slide rails. The output end of the push-pull cylinder is connected to the bottom plate. Side plates are symmetrically installed on the bottom plate. Guide rail sliders are installed on the opposite end faces of the two side plates. The two guide rail sliders and the bottom plate cooperate with each other to jointly install a detection component.

[0006] The detection component includes an upper air cylinder and a lower air cylinder rotatably installed on the bottom plate, and a carrier table rotatably installed on the guide rail slider. A runout measuring instrument is horizontally installed above the carrier table. Supports are arranged at positions above the carrier table near the upper air cylinder and at the middle position below. The cylinder rod of the upper air cylinder is rotatably connected to the support at the upper position. The cylinder rod of the lower air cylinder is in the extended state and is rotatably connected to the support at the middle position below. After the workpiece is turned, the vertical module and the push-pull cylinder cooperate with each other to adjust the position of the bottom plate. Then, the upper air cylinder and the lower air cylinder cooperate with each other to move the runout measuring instrument closer to the end face of the workpiece. After the runout measuring instrument detects the data of the workpiece end face, the vertical module and the push-pull cylinder cooperate with each other to change the position of the bottom plate in real time, so that the runout measuring instrument can perform flatness detection on different positions of the workpiece. When the end face of the workpiece to be detected is in a horizontal state or when the runout measuring instrument needs to be in a vertical state for detection, the lower air cylinder does not work, and the cylinder rod of the upper air cylinder extends. Based on the position distribution of the two supports and the cooperation between the upper air cylinder and the lower air cylinder, the carrier table is changed from a horizontal state to a vertical state, and the runout measuring instrument is changed from a horizontal state to a vertical state. After the carrier table becomes vertical, the lower air cylinder and the upper air cylinder work synchronously to push the carrier table towards the workpiece, so that the runout measuring instrument can perform flatness detection on the end face of the workpiece. The runout measuring instrument transmits the measurement result to the control system. During the detection process, the control system records the stroke data of the vertical module and the push-pull cylinder, and the control system records the measurement result. If the flatness does not meet the requirements, the position of the machining error can be accurately obtained through the stroke data and the detection result of the runout measuring instrument. The control system then controls the drive box, the tool disc, the tool holder, etc. to re-turn the workpiece until the flatness of the end face of the workpiece meets the requirements.

[0007] The flipping mechanism includes an upper module installed above the machine body and a lower module installed on the upper module. A slide plate is installed on the lower module. A plurality of lifting cylinders are installed below the slide plate. The cylinder rods of the lifting cylinders are connected to a carrier plate. Two adjustment slideways are symmetrically opened in the middle of the carrier plate. Short rods are respectively slidably installed in the two adjustment slideways. A clamping cylinder connecting the short rods is installed above the carrier plate. A vertical plate is installed below the short rods.

[0008] A chute is provided on each of the vertical plates. A connecting shaft is slidably installed in the chute. One end of the connecting shaft is provided with an extension plate, and the other end of the connecting shaft is provided with a moving cylinder. The extension plate is slidably connected to the vertical plate. Electric turntables are installed at the lower ends of the opposite end faces of the two extension plates, and the output end of the electric turntable protrudes from the extension plate. When the workpiece needs to be flipped, the upper module and the lower module cooperate with each other to adjust the position of the sliding plate, so that the carrier plate is driven by the lifting cylinder to be directly above the workpiece. The lifting cylinder pushes the carrier plate downward. After the carrier plate is sent to the corresponding height, the two clamping cylinders cooperate with each other to make the vertical plate approach the workpiece, and finally the output end of the electric turntable abuts against the outside of the workpiece and realizes the clamping of the workpiece. Subsequently, the lifting cylinder drives the carrier plate to rise. After the workpiece leaves the clamping mechanism, the moving cylinder pulls the connecting shaft downward, so that the extension plate drives the electric turntable and the workpiece to move downward, providing enough space for the electric turntable to rotate the workpiece by 180°. After the electric turntable rotates the workpiece by 180°, the moving cylinder does not drive the extension plate to reset temporarily. The lifting cylinder lowers the carrier plate, so that the workpiece is first placed on the clamping mechanism, and then the clamping cylinder drives the vertical plate to reset, the electric turntable is separated from the workpiece, and then the lifting cylinder drives the carrier plate to reset, and the moving cylinder drives the extension plate to reset.

[0009] The clamping mechanism includes a rotating disk installed inside the machine body and a casing sleeved outside the rotating disk. The casing is connected to the output end of the rotating disk. Two cushion blocks are symmetrically installed above the casing. Support shafts are installed at both ends of each cushion block. The other end of each support shaft is provided with a shaft seat, and the shaft seat is installed on the casing. Adjusting cylinders are rotatably installed on each support shaft. A base for carrying the workpiece is placed on the two cushion blocks. The base is of an I-shaped structure, and connecting rods are installed at the openings of the I-shaped base. The cylinder rod of the adjusting cylinder is rotatably connected to the connecting rod. A fillet is provided on the lower side of one end of the base close to the cutter head, and a claw structure is provided on the base.

[0010] The base is a box body and a box cover is installed above it. Four claw grooves are provided on the box cover, and compressible sealing gaskets are installed at both ends of each claw groove; The claw structure includes a driving structure installed at the central position inside the box body and clamping plates installed in each claw groove. The clamping plates are located between the two sealing gaskets. A bracket with a cross-shaped frame structure is installed below the clamping plates inside the box body. A connecting block is installed at the central position of the bracket, and the upper end of the connecting block is connected to the box cover. One end of the clamping plate is located on the bracket. A base is installed below the clamping plates inside the box body. The base is located below the bracket, and a cylinder for supporting the clamping plate to rise and fall is installed on the base. The base is of an "L" - shaped structure and is connected to the driving structure.

[0011] The driving structure includes a driving cylinder installed on the box body and a four-pointed star frame installed around the driving cylinder. The four-pointed star frame is composed of several hinge plates rotatably connected. A connecting plate is rotatably installed at the tip of the four-pointed star frame close to the base. The connecting plate is connected to the base through a guide rod. Above the tip of the four-pointed star frame close to the driving cylinder, a chain plate is installed. The chain plate is rotatably connected to the pin shafts at the rotational connection of two hinge plates. Above the driving cylinder, four arc-shaped frames are installed. A linkage shaft is slidably installed in the slideway of the arc-shaped frame. Four rectangular limiting frames are arranged below the connecting block. The linkage shaft passes through one end of the chain plate and is inserted into the limiting frame.

[0012] Two cylinders are installed on the base. The outer parts of both cylinders are sleeved with stepped blocks of box body structure. The two stepped blocks are in a symmetrical relationship. The cylinder rods of the cylinders are connected to the inner end faces of the stepped blocks. The stepped blocks pass through the brackets under the support of the cylinders and push out the clamping plate from the base. A step is arranged at one end of the stepped block close to the clamping plate. A baffle is arranged on one side of the lowest step of the stepped block. The clamping plate is composed of multiple sliding-connected base plates. The thickness of the base plate at the middle position is equal to the thickness of the workpiece. When the stepped block pushes some of the base plates that make up the clamping plate out of the base, the steps on the stepped block cause the multiple base plates to be distributed in a stepped shape from high to low, and the position of the base plate in contact with the workpiece is the highest. By operating the control panel of the turning device, the position where the workpiece needs to be processed first is determined. The air cylinder pushes the corresponding stepped block upward under the control of the control system of the turning device. For example, if the outer end face of the workpiece needs to be processed first, in order to prevent the clamping plate from affecting the turning progress outside the workpiece, the workpiece needs to be placed upside down on the base and pushed tightly from the inside of the workpiece opening to the outside. Therefore, the air cylinder needs to push the stepped block located inside the workpiece opening upward. Conversely, the stepped block located outside the workpiece is pushed upward. During the process of the air cylinder pushing the stepped block upward, the stepped block passes through the bracket and pushes the multiple upper base plates out of the base. The base plates are distributed in a stepped structure on the stepped block. Then, the workpiece is placed on the base. The driving cylinder drives the arc-shaped frame to rotate under the control of the control system. Since the limit frame is fixed and restricts the moving direction of the linkage shaft, during the rotation of the arc-shaped frame, the linkage shaft slides in the limit frame and drives the hinge plate to approach or move away from the driving cylinder. If the base plate is located inside the workpiece, the linkage shaft drives the hinge plate to move away from the driving cylinder, causing the connecting plate to move outward under the drive of the hinge plate, and the guide rod pushes the base toward the direction close to the inner end face of the workpiece, finally making the base plate abut against the inner end face of the workpiece and tightly clamping the workpiece, fixing the workpiece on the base. Conversely, the linkage shaft drives the hinge plate to approach the driving cylinder, and finally the base plate clamps the outside of the workpiece. After the workpiece is clamped and fixed, the moving module pushes the driving box, the tool holder and the tool post toward the workpiece, and uses the tool to turn the surface of the workpiece. During the turning process, the moving module drives the tool to translate on the surface of the workpiece, and the tool holder changes the height of the tool on the surface of the workpiece by rotating the angle. The moving module and the tool holder cooperate with each other to complete the comprehensive turning of each end face of the workpiece. The rotating disk drives the workpiece to rotate through the sleeve and the base, changing the end face to be turned by the tool. When the end face of the workpiece to be turned is in a horizontal state, the workpiece needs to be flipped 90°. So that the tool can turn the end face of the workpiece. At this time, the adjusting air cylinders on both sides of the base cooperate with each other to make the base flip 90° on the two cushion blocks, changing the base from a horizontal state to a vertical state, and changing the originally horizontal end face of the workpiece to a vertical state. After the base flipping is completed, the moving module and the tool holder cooperate with each other to make the tool complete the turning.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: A moving module is installed below the driving box, enabling the tool to process or move away from the workpiece. The clamping mechanism fixes the workpiece and adjusts the posture of the workpiece during the turning process, facilitating the tool to process the inner holes, through grooves and deep grooves on the workpiece. And during the turning process, the flipping mechanism and the clamping mechanism cooperate with each other to realize the flipping of the workpiece, enabling the tool to process different end faces of the workpiece. By the mutual cooperation of the flipping mechanism and the clamping mechanism to replace manual labor, the automation of the turning process is realized.

[0014] The jump measuring instrument transmits the measurement results to the control system. During the detection process, the control system records the stroke data of the vertical module and the push-pull cylinder, and records the measurement results. If the flatness does not meet the requirements, the position of the machining error can be accurately obtained through the stroke data and the detection results of the jump measuring instrument. Then the control system controls the drive box, the cutter head, the tool holder, etc. to re-turn the workpiece until the flatness of the workpiece end face meets the requirements.

[0019] The clamping mechanism 6 includes a rotating disk 26 installed inside the body 1 and a casing sleeved outside the rotating disk 26.

Adjusting cylinders 13 are rotatably installed on each support shaft. A base 9 for carrying the workpiece is placed on the two cushion blocks 11. The base 9 is of an I-shaped structure. Connecting rods 10 are installed at the openings of the I-shaped base 9. The connecting rods 10 are close to the lower end face of the base 9. Through the setting of the position of the connecting rods 10, it is convenient for the adjusting cylinder 13 to drive the base 9 to flip without the base 9 blocking the cylinder rod of the adjusting cylinder 13. The cylinder rod of the adjusting cylinder 13 is rotatably connected to the connecting rod 10. A fillet is provided on the lower side of one end of the base 9 close to the tool disc 4. A claw structure is provided on the base 9.

[0020] The base 9 is a box body and a box cover is installed above it. Four claw grooves are provided on the box cover. Compressible sealing gaskets 14 are installed at both ends of each claw groove; The jaw structure includes a driving structure installed at the central position inside the box body and a clamping plate 15 installed in each jaw groove. The clamping plate 15 is located between two sealing gaskets 14. Inside the box body, a bracket 16 with a cross-shaped frame structure is installed below the clamping plate 15. At the central position of the bracket 16, a connecting block 20 is installed. The upper end of the connecting block 20 is connected to the box cover.

[0021] The driving structure includes a driving cylinder 27 installed on the box body and a four-pointed star frame installed around the driving cylinder 27. The four-pointed star frame is composed of several hinge plates 21 rotatably connected. At the tip of the four-pointed star frame close to the base 18, a connecting plate 25 is rotatably installed.

[0022] Two cylinders are installed on the base 18. The outer parts of both cylinders are sleeved with stepped blocks 17 with a box body structure. The two stepped blocks 17 are in a symmetrical relationship. The cylinder rod is connected to the inner end face of the stepped block 17. The stepped block 17 passes through the bracket 16 under the support of the cylinder and pushes the clamping plate 15 out of the base 9. At one end of the stepped block 17 close to the clamping plate 15, a step is provided. At one side of the lowest step of the stepped block 17, a baffle is provided; The clamping plate 15 is composed of multiple substrate plates connected in a sliding manner. The thickness of the substrate plate at the middle position is equal to the thickness of the workpiece. When the stepped block 17 pushes some of the substrate plates forming the clamping plate 15 out of the base 9, the steps on the stepped block 17 make the multiple substrate plates distributed in a stepped shape from high to low, and the substrate plate in contact with the workpiece is at the highest position.

[0023] The flipping mechanism 7 includes an upper module 70 installed above the machine body 1 and a lower module 71 installed on the upper module 70. A sliding plate 72 is installed on the lower module 71. Below the sliding plate 72, multiple lifting cylinders 73 are installed.

Below the short rod 76, a vertical plate 75 is installed.

[0024] A chute is provided on each vertical plate 75. A connecting shaft is slidably installed in the chute. One end of the connecting shaft is installed with an extension plate 78, and the other end of the connecting shaft is installed with a moving cylinder 79. The extension plate 78 is slidably connected to the vertical plate 75. Electric turntables are installed at the lower ends of the opposite end faces of the two extension plates 78, and the output ends of the electric turntables protrude from the extension plates 78.

[0025] The detection mechanism 8 includes a vertical module 80 vertically installed on one side of the machine body 1 and a slide rail and slider. The vertical module 80 and the slide rail and slider are jointly installed with a support plate. Slide rails 81 and push-pull cylinders 82 are symmetrically installed on the support plate. The push-pull cylinder 82 is located between the two slide rails 81. A bottom plate 83 is installed on the slide rail 81. The output end of the push-pull cylinder 82 is connected to the bottom plate 83. Side plates 84 are symmetrically installed on the bottom plate 83. Guide rail sliders 85 are installed on the opposite end faces of the two side plates 84. The two guide rail sliders 85 and the bottom plate 83 cooperate with each other to jointly install a detection component.

[0026] The detection component includes an upper air cylinder 87 and a lower air cylinder 88 rotatably installed on the bottom plate 83 and a load platform 86 rotatably installed on the guide rail slider 85. A runout measuring instrument is horizontally installed above the load platform 86. Supports are provided at positions above the load platform 86 near the upper air cylinder 87 and at the middle position below. The cylinder rod of the upper air cylinder 87 is rotatably connected to the support at the upper position, and the cylinder rod of the lower air cylinder 88 is in the extended state and is rotatably connected to the support at the middle position below.

[0027] The working principle of the present invention: By operating the control panel of the turning device, determine the position where the workpiece needs to be processed first. The cylinder pushes the corresponding stepped block 17 upwards under the control of the control system of the turning device. During the process of the cylinder pushing the stepped block 17 upwards, the stepped block 17 passes through the bracket 16 and pushes out multiple substrates above from the base 9. The substrates are distributed in a stepped structure on the stepped block 17. Then, place the workpiece on the base 9. The driving cylinder 27 drives the arc-shaped frame 24 to rotate under the control of the control system. Since the limit frame 22 is fixed and restricts the moving direction of the linkage shaft, during the rotation of the arc-shaped frame 24, the linkage shaft slides in the limit frame 22 and drives the hinge plate 21 to approach or move away from the driving cylinder 27; If the substrate is located inside the workpiece (that is, the workpiece is buckled on the base 9 with the opening of the workpiece facing the base 9), the linkage shaft drives the hinge plate 21 to move away from the driving cylinder 27, so that the connecting plate 25 moves outwards under the drive of the hinge plate 21, and the guide rod 19 pushes the base 18 towards the direction close to the inner end face of the workpiece, and finally the substrate abuts against the inner end face of the workpiece and presses the workpiece tightly, fixing the workpiece on the base 9. On the contrary, the linkage shaft drives the hinge plate 21 to approach the driving cylinder 27, and finally the substrate is clamped outside the workpiece (that is, the workpiece is placed upright on the base 9 with the opening of the workpiece not facing the base 9).

[0028] After the workpiece is clamped and fixed, the moving module pushes the drive box 3, the cutter head 4 and the tool holder 5 closer to the workpiece, and uses the tool to turn the surface of the workpiece. During the turning process, the moving module drives the tool to translate on the surface of the workpiece. The cutter head 4 changes the height of the tool on the surface of the workpiece by rotating the angle. The moving module and the cutter head 4 cooperate with each other to complete the overall turning of each end face of the workpiece. The rotating disk 26 drives the workpiece to rotate through the housing and the base 9, changing the end face turned by the tool. When the end face of the workpiece to be turned is in a horizontal state, the workpiece needs to be flipped by 90° so that the tool can turn the end face of the workpiece. At this time, the adjusting cylinders 13 on both sides of the base 9 cooperate with each other. The adjusting cylinder 13 close to the cutter head 4 does not work, and the adjusting cylinder 13 far from the cutter head 4 works. As the piston rod of the adjusting cylinder 13 continuously extends, the base 9 rotates around the connecting rod 10 close to the cutter head 4, and finally the base 9 flips by 90° on the two cushion blocks 11, changing the base 9 from a horizontal state to a vertical state, and changing the originally horizontal end face of the workpiece to a vertical state. After the base 9 finishes flipping, the moving module and the cutter head 4 cooperate with each other to make the tool complete the turning.

[0029] When the workpiece needs to be flipped (that is, when turning the inner end face or the outer end face of the workpiece), the upper module 70 and the lower module 71 cooperate with each other to adjust the position of the slide plate 72, so that the carrier plate 74 is located directly above the workpiece driven by the lifting cylinder 73. The lifting cylinder 73 pushes the carrier plate 74 downward. After the carrier plate 74 is sent to the corresponding height, the two clamping cylinders 77 cooperate with each other to make the vertical plate 75 approach the workpiece. Finally, the output end of the electric turntable abuts against the outside of the workpiece and clamps the workpiece. The clamping mechanism 6 releases the workpiece. Then the lifting cylinder 73 drives the carrier plate 74 to rise. After the workpiece leaves the clamping mechanism 6, the moving cylinder 79 pulls the coupling shaft downward, so that the extension plate 78 drives the electric turntable and the workpiece to move downward, providing enough space for the electric turntable to rotate the workpiece by 180°. After the electric turntable rotates the workpiece by 180°, the moving cylinder 79 does not drive the extension plate 78 to reset temporarily. The lifting cylinder 73 lowers the carrier plate 74, so that the workpiece is first placed on the clamping mechanism 6. The clamping mechanism 6 clamps the workpiece again. Then the clamping cylinder 77 drives the vertical plate 75 to reset, and the electric turntable is separated from the workpiece. Then the lifting cylinder 73 drives the carrier plate 74 to reset, and the moving cylinder 79 drives the extension plate 78 to reset.

[0030] After the flipping mechanism 7 is fully reset, the moving module pushes the drive box 3, the cutter head 4 and the tool holder 5 closer to the workpiece again, and uses the tool to turn the surface of the workpiece.

[0031] After the workpiece is turned, the vertical module 80 and the push-pull cylinder 82 cooperate with each other to adjust the position of the bottom plate 83. Then, the upper cylinder 87 and the lower cylinder 88 cooperate with each other to make the runout measuring instrument approach the end face of the workpiece. After the runout measuring instrument detects the data of the workpiece end face, the vertical module 80 and the push-pull cylinder 82 cooperate with each other to change the position of the bottom plate 83 in real time, so that the runout measuring instrument can perform flatness detection on different positions of the workpiece.

[0032] When the end face of the workpiece to be detected is in a horizontal state or when the runout measuring instrument needs to be in a vertical state for detection, the lower cylinder 88 does not work, and the cylinder rod of the upper cylinder 87 extends. Based on the position distribution of the two supports and the cooperation between the upper cylinder 87 and the lower cylinder 88, the carrier table 86 is changed from a horizontal state to a vertical state, and the runout measuring instrument is changed from a horizontal state to a vertical state. After the carrier table 86 becomes vertical, the lower cylinder 88 and the upper cylinder 87 work synchronously to push the carrier table 86 towards the workpiece, so that the runout measuring instrument can perform flatness detection on the end face of the workpiece.

[0033] The runout measuring instrument transmits the measurement result to the control system, and the control system records the measurement result. If the flatness does not meet the requirements, the control system controls the drive box 3, the tool holder 4, the tool post 5, etc. to re-turn the workpiece until the flatness of the end face of the workpiece meets the requirements.

[0034] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.
