Description

Technical Field

[0001] The present invention relates to the technical field of air compressor measuring devices, and more specifically, to a three-coordinate measuring device for an air compressor housing. Background Art

[0002] Three-coordinate measurement is a precise measurement method for inspecting workpieces. It is widely used in modern industries such as machinery manufacturing and automobile industry. Three-coordinate measurement is to use a three-coordinate measuring machine to inspect and measure the shape and position tolerance of the workpiece to determine whether the error of the workpiece is within the tolerance range. It is also called three-coordinate measurement.

[0003] A Chinese patent with publication number CN118936382A discloses a three-coordinate measuring device for a workpiece and a measuring method thereof, comprising a workbench, a gantry is installed on the top of the workbench, a measuring structure is installed on the outer wall of the gantry, a placing table is arranged below the measuring structure, a workpiece is arranged on the top of the placing table, a first fixing component is arranged on the outer wall of the workpiece, a second fixing component is arranged inside the workpiece, the first fixing component comprises a fixing plate arranged on the outer wall of the workpiece, two fixing plates are symmetrically arranged, the bottom ends of the two fixing plates are fixedly connected with moving rods, the two moving rods are slidably installed inside the placing table, the inner walls of the two moving rods are embedded with second threaded rods, a second motor is installed at one end of the second threaded rod, and the second fixing component comprises a fixing block arranged inside the workpiece. The device fixes the inner wall and outer wall of the workpiece respectively, so as to facilitate the measurement of the inner wall and outer wall of the workpiece and improve the working efficiency of the device.

[0004] Although the above invention can fix the inner and outer walls of the measuring piece, when a similar measuring device is used to measure the air compressor casing, the above invention cannot adapt to the shape of the air compressor casing for effective clamping due to the different types and shapes of air compressor casings. In addition, since the air compressor casing is relatively heavy, the above device cannot control the clamping force when clamping the measuring piece. If the clamping force is insufficient, the air compressor casing cannot be effectively fixed, which may cause the casing to slip or fall during transportation, thereby causing a safety accident. If the clamping force is too great, it may cause physical damage to the air compressor casing, such as scratches, deformation or other structural damage, which will not only affect the normal operation of the equipment, but may also increase maintenance costs.

[0017] Technical effects and advantages of the present invention: 1. The present invention provides a clamping assembly, when the two clamping assemblies are close to each other to clamp the air compressor housing, the raised part on the surface of the air compressor housing will squeeze the telescopic rod at the corresponding position, and the telescopic rod at the corresponding position will push the corresponding piston to slide in the corresponding telescopic groove, so as to adapt to the shape of the air compressor housing, and the piston will compress the gas in the air storage chamber during the sliding process in the telescopic groove, and the gas can play a buffering role, and the larger the volume of the air compressor housing, the more telescopic rods will be squeezed, and the more seriously the gas in the air storage chamber will be compressed, which can provide a greater supporting force for the remaining telescopic rods, so that the supporting effect can be adjusted according to the volume of the air compressor housing, and the phenomenon of the telescopic rod retracting when the air compressor housing is turned over can be prevented, and the air compressor housing can be prevented from slipping or falling during transportation and turning, thereby improving the safety during the measurement process.

[0018] 2. The present invention provides a first conductive contact piece and a second conductive contact piece. When the convex part on the surface of the air compressor housing squeezes the telescopic rod at the corresponding position to drive the piston to move to the inner limit position of the telescopic slot, the first conductive contact piece and the second conductive contact piece can contact and generate an electrical signal. After receiving the electrical signal, the controller can stop the rotation of the first motor, thereby stopping the two clamping components from approaching each other, so as to control the clamping force and prevent the clamping force from continuing to increase, thereby protecting the air compressor housing and preventing the air compressor housing from slipping or falling during transportation due to insufficient clamping force and failure to effectively fix the air compressor housing. At the same time, it also prevents excessive clamping force from causing physical damage to the air compressor housing, thereby ensuring the normal operation of the equipment, reducing maintenance costs, and improving measurement efficiency. 3. The present invention sets a control mechanism. When the second piston plate drives the piston rod to fully extend from the inside of the control chamber, the first magnetic part can push the magnetic sealing plate to release the blockage of the exhaust groove through the repulsion of like poles. The gas in the control chamber will gradually be discharged from the exhaust groove. At this time, the second elastic part can drive the second piston plate and the piston rod to gradually return to the initial position through the moving part to drive the cylinder. In this process, directly starting the first motor cannot drive the first gear to rotate, so that after the two clamping components completely clamp the air compressor casing, it can play a role in protecting against misoperation and avoid safety hazards.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1 Since air compressor casings come in different types and shapes, the three-coordinate measuring device in the prior art cannot adapt to the shape of the air compressor casing for effective clamping and cannot effectively fix the air compressor casing, which may cause the casing to slip or fall during transportation, thereby causing a safety accident. This will not only affect the normal operation of the equipment, but may also increase maintenance costs.

[0035] refer to Figure 1A three-coordinate measuring device for an air compressor casing according to an embodiment of the present invention comprises a measuring platform 1, a motion mechanism 2 is arranged on one side of the measuring platform 1, and a measuring mechanism 3 is arranged on the motion mechanism 2. The motion mechanism 2 comprises a movable slide 21 arranged on one side of the measuring platform 1 for moving the measuring mechanism 3 in the Y direction, a gantry slide 22 for moving the measuring mechanism 3 in the X direction is slidably connected to the movable slide 21, and the measuring mechanism 3 comprises a slide 31 with a telescopic function slidably connected to the gantry slide 22, and a measuring probe 32 is arranged below the slide 31.

[0036] refer to Figures 1 to 7 , and also includes an adjustment mechanism 4, which is arranged on the measuring table 1. Two groups of clamping assemblies 5 are arranged on the adjustment mechanism 4. The clamping assembly 5 includes a clamping seat 51. A plurality of telescopic grooves 52 are evenly opened on one side of the clamping seat 51. A piston 53 is sealed and slidably connected in each telescopic groove 52. A telescopic rod 54 capable of extending out of the telescopic groove 52 is fixedly connected to one side of each piston 53. The adjustment mechanism 4 is used to adaptively clamp the air compressor housing. The adjustment mechanism 4 is used to adjust the position of the clamping assembly 5. An air storage cavity 55 connected to each telescopic groove 52 is opened inside the clamping seat 51. A rotating block 56 is fixedly connected to the side of the clamping seat 51 away from the telescopic groove 52.

[0037] refer to Figures 1 to 11 The adjustment mechanism 4 includes a bidirectional threaded rod 41 and a sliding rod 42. A moving cavity 43 is opened on the top of the measuring platform 1. The bidirectional threaded rod 41 and the sliding rod 42 are both rotatably connected to the inside of the moving cavity 43 and are arranged in parallel. A first gear 44 is fixedly connected to the bidirectional threaded rod 41, and a second gear 45 is fixedly connected to the sliding rod 42. A first motor 46 is fixedly connected to the inside of the moving cavity 43. The output end of the first motor 46 is slidably connected to a moving sleeve 47 through a key, and a third gear 48 that can mesh with the first gear 44 and the second gear 45 is fixedly connected to the moving sleeve 47.

[0038] refer to Figure 2 and Figures 10 to 12 A cylinder 49 is provided inside the movable chamber 43. The output end of the cylinder 49 is rotatably connected to an end of the movable sleeve 47 away from the first motor 46 through a rotating member 410. When the output end of the cylinder 49 is fully extended, the third gear 48 is meshed with the first gear 44. When the output end of the cylinder 49 is fully retracted, the third gear 48 is meshed with the second gear 45.

[0039] refer to Figures 2 to 5The interior of the moving cavity 43 is slidably connected to two symmetrically arranged support columns 411. The two support columns 411 are provided with threaded holes 412 arranged in a through shape in the interior of the moving cavity 43 on the side close to each other. The two support columns 411 are threadedly connected to the bidirectional threaded rod 41 through the corresponding threaded holes 412. When the bidirectional threaded rod 41 rotates, the two support columns 411 can be driven to move away from or approach each other. The two support columns 411 are provided with guide grooves 413 on the upper side of the moving cavity 43 on the side close to each other. The two guide grooves 413 are provided on the upper side of the moving cavity 43. 13 are both rotatably connected with threaded rods 414, and moving blocks 415 threadedly connected to the corresponding threaded rods 414 are slidably connected in the two guide grooves 413. When the two threaded rods 414 rotate, they can drive the corresponding moving blocks 415 to move up and down in the corresponding guide grooves 413. The two groups of clamping components 5 are rotatably connected to the side where the two moving blocks 415 are close to each other through the corresponding rotating blocks 56. The second motors 416 are arranged inside the two moving blocks 415, and the output ends of the two second motors 416 are fixedly connected to the corresponding rotating blocks 56.

[0040] refer to Figures 3 to 5 A driving cavity 417 is provided inside the two support columns 411 below the corresponding guide groove 413, and one end of the two threaded rods 414 extending to the corresponding driving cavity 417 is fixedly connected to the first bevel gear 418, and a rotating hole 419 connected to the corresponding driving cavity 417 is provided on the side of the two support columns 411 close to each other, and the inside of the two rotating holes 419 is rotatably connected to the second bevel gear 420 meshing with the corresponding first bevel gear 418, and the sliding rod 42 is slidably connected to the two second bevel gears 420 through a limit bar 421, and the motion mechanism 2, the measuring mechanism 3, the adjustment mechanism 4, and the controller are electrically connected to the control handle 11.

[0041] In actual use, the air compressor housing is placed on the measuring table 1 through the support block, and the motion mechanism 2 and the measuring mechanism 3 can be moved manually through the handle 11 or controlled by the controller, and the three-coordinate measurement of the air compressor housing is performed through the measuring probe 32.

[0042] When the air compressor housing is clamped and the height of the two clamping assemblies 5 needs to be adjusted, first control the cylinder 49 to retract, and drive the third gear 48 to engage with the second gear 45 through the movable sleeve 47, and then control the first motor 46 to rotate. The output end of the first motor 46 drives the movable sleeve 47 and the third gear 48 to rotate through the key, and the third gear 48 drives the second gear 45 and the sliding rod 42 to rotate. The sliding rod 42 drives the two second bevel gears 420 to rotate in the corresponding rotating hole 419 through the limit bar 421. The two second bevel gears 420 drive the corresponding threaded rods 414 to rotate by engaging with the corresponding first bevel gears 418. During the rotation process, the two threaded rods 414 will drive the two clamping assemblies 5 to move synchronously through the corresponding movable blocks 415, and the height of the two clamping assemblies 5 can be adjusted by controlling the forward and reverse rotation of the first motor 46.

[0043] When it is necessary to adjust the distance between the two clamping assemblies 5, first control the cylinder 49 to extend, drive the third gear 48 to engage with the first gear 44 through the movable sleeve 47, and then control the first motor 46 to rotate. The output end of the first motor 46 drives the movable sleeve 47 and the third gear 48 to rotate through the key, and the third gear 48 drives the first gear 44 and the bidirectional threaded rod 41 to rotate. When the bidirectional threaded rod 41 rotates, it drives the two support columns 411 to move synchronously through the threaded connection with the two threaded holes 412. The distance between the two clamping assemblies 5 is adjusted by controlling the forward and reverse rotation of the first motor 46.

[0044] When the two clamping assemblies 5 are close to each other to clamp the air compressor housing, the surface of the air compressor housing will contact the several telescopic rods 54 on the clamping seat 51, and the raised parts on the surface of the air compressor housing will squeeze the telescopic rods 54 at the corresponding positions, and the telescopic rods 54 at the corresponding positions will push the corresponding pistons 53 to slide in the corresponding telescopic grooves 52, so as to adapt to the shape of the air compressor housing. The piston 53 will compress the gas in the air storage chamber 55 during the sliding process in the telescopic groove 52, and the gas can play a buffering role at this time. The larger the volume of the air compressor housing, the more telescopic rods 54 will be squeezed, and the more severely the gas in the air storage chamber 55 is compressed, which can provide greater supporting force for the remaining telescopic rods 54, so that the supporting effect can be adjusted according to the volume of the air compressor housing to prevent the telescopic rods 54 from retracting when the air compressor housing is flipped, thereby improving safety.

[0045] When the air compressor housing needs to be flipped, the two second motors 416 are started, and the two second motors 416 drive the clamping seat 51 to rotate through the corresponding rotating blocks 56. At this time, the clamping seat 51 can drive the clamped air compressor housing to flip through a plurality of telescopic rods 54.

[0046] To sum up, through the setting of the clamping assembly 5, when the two clamping assemblies 5 are close to each other to clamp the air compressor housing, the raised part on the surface of the air compressor housing will squeeze the telescopic rod 54 at the corresponding position, and the telescopic rod 54 at the corresponding position will push the corresponding piston 53 to slide in the corresponding telescopic groove 52, so as to adapt to the shape of the air compressor housing. The piston 53 will compress the gas in the air storage chamber 55 during the sliding process in the telescopic groove 52, and the gas can play a buffering role. Moreover, the larger the volume of the air compressor housing, the more telescopic rods 54 are squeezed, and the more seriously the gas in the air storage chamber 55 is compressed, which can provide greater supporting force for the remaining telescopic rods 54, so that the supporting effect can be adjusted according to the volume of the air compressor housing to prevent the telescopic rod 54 from retracting when the air compressor housing is flipped, and can prevent the air compressor housing from slipping or falling during transportation and flipping, thereby improving safety.

[0047] Embodiment 2 During actual use, the adjustment mechanism 4 cannot control the clamping force when driving the clamping assembly 5 to clamp the air compressor casing. If the clamping force is insufficient, the air compressor casing cannot be effectively fixed, which may cause the casing to slip or fall during transportation, thereby causing a safety accident. If the clamping force is too large, it may cause physical damage to the air compressor casing, such as scratches, deformation or other structural damage, which will not only affect the normal operation of the equipment, but also may increase maintenance costs. Therefore, this embodiment improves the device described in the above embodiment.

[0048] refer to Figure 2 , Figure 7 and Figure 8 , control mechanism 6, the control mechanism 6 is arranged on the adjustment mechanism 4, the control mechanism 6 includes a first conductive contact 61 fixedly connected to the side of the piston 53 away from the telescopic rod 54, and the second conductive contact 62 is fixedly sleeved inside the telescopic slot 52. When the telescopic rod 54 is squeezed to push the piston 53 to move to the extreme position in the telescopic slot 52, the first conductive contact 61 and the second conductive contact 62 can contact and generate an electrical signal for controlling the clamping force of the adjustment mechanism 4 on the air compressor casing when the adjustment mechanism 4 clamps the air compressor casing. The control mechanism 6 is electrically connected to the controller, and the controller can receive the electrical signals generated by the first conductive contact 61 and the second conductive contact 62, and control the start and stop of the first motor 46.

[0049] In actual use, when the two clamping assemblies 5 approach each other to clamp the air compressor housing, the raised part on the surface of the air compressor housing squeezes the telescopic rod 54 at the corresponding position to drive the piston 53 to move to the internal limit position of the telescopic groove 52, and the first conductive contact piece 61 and the second conductive contact piece 62 can contact and generate an electrical signal. After receiving the electrical signal, the controller can stop the rotation of the first motor 46, thereby stopping the two clamping assemblies 5 from approaching each other, thereby controlling the clamping force and preventing the clamping force from continuing to increase, thereby protecting the air compressor housing. On the one hand, it avoids insufficient clamping force, which cannot effectively fix the air compressor housing, causing the housing to slip or fall during transportation; on the other hand, it avoids excessive clamping force, which causes physical damage to the air compressor housing, thereby ensuring the normal operation of the equipment, reducing maintenance costs, and improving measurement efficiency.

[0050] To summarize, through the setting of the first conductive contact piece 61 and the second conductive contact piece 62, when the raised part on the surface of the air compressor housing squeezes the telescopic rod 54 at the corresponding position to drive the piston 53 to move to the internal limit position of the telescopic groove 52, the first conductive contact piece 61 and the second conductive contact piece 62 can contact and generate an electrical signal. After receiving the electrical signal, the controller can stop the rotation of the first motor 46, thereby stopping the two clamping components 5 from approaching each other, so as to control the clamping force and prevent the clamping force from continuing to increase, thereby protecting the air compressor housing. On the one hand, it avoids insufficient clamping force and inability to effectively fix the air compressor housing, causing the housing to slip or fall during transportation. On the other hand, it avoids excessive clamping force and causes physical damage to the air compressor housing, thereby ensuring the normal operation of the equipment, reducing maintenance costs, and improving measurement efficiency.

[0051] Embodiment 3 In actual use, although the control mechanism 6 can control the first motor 46 to stop the two clamping components 5 from approaching each other according to the electrical signal of the contact between the first conductive contact piece 61 and the second conductive contact piece 62, during manual operation, the user may carelessly forget to control the cylinder 49 to switch the meshing state between the third gear 48 and the first gear 44 and the second gear 45. In this way, directly starting the first motor 46 will cause the two clamping components 5 to continue to approach or move away from each other, resulting in the clamping force of the air compressor casing being too large or too small, which may easily cause a safety hazard. Therefore, this embodiment improves the device described in the above embodiment.

[0052] refer to Figures 6 to 13The interior of the rotating block 56 is provided with an adjusting chamber 63 which is connected to the interior of the air storage chamber 55. The interior of the adjusting chamber 63 is sealed and slidably connected with a first piston plate 64. A first elastic member 65 is connected between the side of the first piston plate 64 away from the air storage chamber 55 and the adjusting chamber 63. The side of the first piston plate 64 close to the air storage chamber 55 is fixedly connected with a push plate 67 through a support member 66. The surface of the push plate 67 is provided with slots for air circulation. The other end of each piston 53 away from the corresponding telescopic rod 54 is fixedly connected with an extrusion rod 68. When the extrusion telescopic rod 54 pushes the piston 53 to move to the extreme position in the telescopic groove 52, the extrusion rod 68 can squeeze the push plate 67 to push the first piston plate 64 to compress the gas inside the air storage chamber 55.

[0053] refer to Fig.12 and Fig.13 The control mechanism 6 also includes a fixing member 69, a control chamber 610 is provided inside the fixing member 69, a second piston plate 611 is sealingly and slidably connected inside the control chamber 610, a piston rod 612 which can extend out of the control chamber 610 is fixedly connected to one side of the second piston plate 611, a moving member 613 is fixedly connected to one end of the piston rod 612 away from the second piston plate 611, a second elastic member 614 is connected between the side of the second piston plate 611 away from the piston rod 612 and the control chamber 610, and a sealing member 614 is rotatably connected to the outer wall of the circumference of the rotating block 56. The sealing sleeve 615 and the regulating chamber 63 are provided with an air outlet 616 connected to the sealing sleeve 615. The sealing sleeve 615 is provided with an air inlet end and an air outlet end. A one-way valve 617 is provided in the air inlet end of the sealing sleeve 615. The air outlet end of the sealing sleeve 615 is connected with the interior of the control chamber 610 through the air pipe 618. When the rotating block 56 rotates, due to the rotating connection relationship with the sealing sleeve 615, the rotating block 56 will not force the sealing sleeve 615 to rotate, and will not affect the connection between the air pipe 618 and the fixing part 69.

[0054] refer to Fig.13 A venting groove 619 is provided on one side of the second piston plate 611, a sealing groove 620 penetrating the venting groove 619 is provided inside the second piston plate 611, a magnetic sealing plate 621 for sealing the venting groove 619 is slidably connected inside the sealing groove 620, and a first magnetic component 622 and a second magnetic component 623 are fixedly embedded inside the control chamber 610.

[0055] When the second piston plate 611 drives the piston rod 612 to fully extend from the interior of the control chamber 610, the position of the first magnetic component 622 corresponds to that of the magnetic sealing plate 621, and the first magnetic component 622 can push the magnetic sealing plate 621 to release the blockage of the exhaust groove 619 through the repulsion of like poles. When the second piston plate 611 drives the piston rod 612 to fully retract into the interior of the control chamber 610, the second magnetic component 623 corresponds to the position of the magnetic sealing plate 621, and the second magnetic component 623 can drive the magnetic sealing plate 621 to block the exhaust groove 619 through the attraction of opposite poles.

[0056] refer to Fig.11 The fixing member 69 is fixedly connected inside the moving chamber 43, and the cylinder 49 is fixedly connected to the moving member 613. When the piston rod 612 is fully extended, the third gear 48 on the cylinder 49 in the fully extended state can be driven to release the meshing with the first gear 44.

[0057] In actual use, when the two clamping assemblies 5 are close to each other to clamp the air compressor housing, the convex part on the surface of the air compressor housing squeezes the telescopic rod 54 at the corresponding position to drive the piston 53 to move to the limit position inside the telescopic groove 52, and the telescopic rod 54 and the piston 53 at the corresponding position will drive the squeezing rod 68 to move, and the squeezing rod 68 will squeeze the push plate 67 and drive the first piston plate 64 to slide in the adjustment chamber 63 through the support member 66, and compress the first elastic member 65. During the sliding process of the first piston plate 64 in the adjustment chamber 63, the gas in the adjustment chamber 63 will be The gas is squeezed into the sealing sleeve 615 through the air outlet hole 616. Since a one-way valve 617 is provided in the air inlet end of the sealing sleeve 615, the gas cannot be discharged from the air inlet end. At this time, the gas will be input into the control chamber 610 through the air outlet end and the air pipe 618. The second piston plate 611 in the initial state is in a fully retracted state under the pulling force of the second elastic member 614. At this time, the second magnetic member 623 corresponds to the position of the magnetic sealing plate 621. The second magnetic member 623 can drive the magnetic sealing plate 621 to seal the exhaust groove 619 through the attraction of the opposite poles of the magnetic poles. Fig.11 When the gas in the regulating chamber 63 enters the control chamber 610, the gas pushes the second piston plate 611 to drive the piston rod 612 to extend out of the control chamber 610 and stretch the second elastic member 614. During the extension of the piston rod 612, the third gear 48 on the fully extended cylinder 49 is driven by the moving member 613 to release the meshing with the first gear 44. When the second piston plate 611 drives the piston rod 612 to fully extend from the inside of the control chamber 610, the position of the first magnetic part 622 corresponds to the position of the magnetic sealing plate 621. The first magnetic part 622 can push the magnetic sealing plate 621 to release the blockage of the exhaust groove 619 through the repulsion of the like poles. The gas in the control chamber 610 will gradually be discharged from the exhaust groove 619. At this time, the second elastic part 614 can drive the second piston plate 611 and the piston rod 612 to gradually retract, and can drive the cylinder 49 to gradually return to the initial position through the moving part 613. The time for the cylinder 49 to return to the initial position can be adjusted by adjusting the size of the exhaust groove 619. In this process, if the cylinder 49 is manually forgotten to switch the meshing state between the third gear 48 and the first gear 44 and the second gear 45, directly starting the first motor 46 cannot drive the first gear 44 to rotate, so that after the two clamping components 5 completely clamp the air compressor casing, it can play a role in protecting against misoperation and avoid safety hazards.

[0058] When the two clamping assemblies 5 move away from each other and the pistons 53 and the telescopic rods 54 return to their initial positions, the extrusion rod 68 no longer exerts an extrusion effect on the push plate 67 and the first piston plate 64, and the first elastic member 65 pushes the first piston plate 64 back to its initial position. During the process of the first piston plate 64 returning to its initial position in the regulating chamber 63, external gas will be drawn into the regulating chamber 63 through the air inlet end and the one-way valve 617, so as to prepare for the next misoperation protection.

[0059] To sum up, through the setting of the control mechanism 6, when the second piston plate 611 drives the piston rod 612 to fully extend from the inside of the control chamber 610, the first magnetic member 622 can push the magnetic sealing plate 621 to release the blockage of the exhaust groove 619 through the like-sex repulsion of the magnetic poles, and the gas in the control chamber 610 will gradually be discharged from the exhaust groove 619. At this time, the second elastic member 614 can drive the second piston plate 611 and the piston rod 612 to drive the cylinder 49 to gradually return to the initial position through the moving member 613. In this process, directly starting the first motor 46 cannot drive the first gear 44 to rotate, so that after the two clamping components 5 completely clamp the air compressor casing, it can play a role in protecting against misoperation and avoid safety hazards.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
