Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, and more specifically, to a workpiece processing apparatus for spherical or irregularly shaped workpieces. Background Technology

[0002] In industrial production and workpiece assembly processes, workers often need to clamp workpieces to perform machining operations. For spherical or irregularly shaped workpieces, their outer surfaces are not easy to clamp, making machining more difficult. Furthermore, when machining the entire outer surface of a workpiece is required, it is necessary to use only the inner surface for gripping and machining.

[0003] Existing technologies include internal support structures that can extend into the workpiece to support it. However, these internal support structures are in hard contact with the inside of the workpiece, which may cause damage to the internal support structure itself or the inside of the workpiece. Summary of the Invention

[0004] The present invention aims to provide, for example, a processing device for spherical or irregularly shaped workpieces, which can achieve flexible gripping of the workpiece and is applicable to the gripping and processing of spherical and irregularly shaped workpieces, while avoiding damage to the inner surface of the workpiece. Furthermore, this processing device can integrate multi-functional processing requirements such as rotary processing and self-cleaning, and has a simple structure and a high degree of automation.

[0011] A second bearing is sleeved on the airbag shaft, a second bearing seat is sleeved on the second bearing, and the second bracket is connected to the second bearing seat;

[0012] The piston rod of the third drive cylinder is coaxially connected to the airbag auxiliary shaft.

[0013] Optionally, both the first bearing and the second bearing may include a deep groove bearing and a thrust bearing.

[0014] Optionally, the processing device further includes a second drive mechanism, which includes a first motor and a gear set. The first motor is mounted on the first bracket, and the output shaft of the first motor extends horizontally and is connected to the gear set for transmission. An outer gear is sleeved on the outside of the outer shaft, and the gear set is in transmission engagement with the outer gear. When the outer shaft rotates, the airbag shaft rotates synchronously with the outer shaft.

[0015] Optionally, the gear set includes two meshing bevel gears and a driven gear, the output shaft of the first motor extends horizontally and is drivenly connected to one of the bevel gears, the other bevel gear is coaxially connected to the driven gear, and the driven gear meshes with the outer gear.

[0016] Optionally, a keyway is provided on the outer sleeve shaft, and a flat key is provided on the airbag shaft, with the keyway cooperating with the flat key.

[0017] Optionally, the processing device further includes a processing mechanism, which includes a fourth driving cylinder, a fifth driving cylinder, and a processing part for processing spherical workpieces. The fourth driving cylinder is mounted on the frame, and the piston rod of the fourth driving cylinder extends vertically upward and is connected to the fifth driving cylinder. The piston rod of the fifth driving cylinder extends horizontally and is connected to the processing part.

[0018] Optionally, the processing device further includes a cleaning mechanism, which includes a second motor, a sixth drive cylinder, and a cleaning tank containing cleaning fluid. The second motor is mounted on the frame, and the output shaft of the second motor extends vertically upward and is connected to the sixth drive cylinder.

[0019] Optionally, the frame is provided with a support plate, the support plate is provided with a third bearing, the support plate is provided with a support shaft for supporting spherical workpieces, the bottom of the support shaft cooperates with the third bearing, and the third bearing includes a deep groove bearing and a thrust bearing.

[0020] Optionally, the support plate is movably mounted on the frame in the horizontal direction.

[0021] Optionally, the processing device further includes a waste collection vehicle, which is positioned directly below the airbag.

[0022] Optionally, the airbag may be provided with multiple suction cups on its exterior.

[0023] The beneficial effects of the processing apparatus for spherical or irregularly shaped workpieces of the present invention include, for example: before processing the spherical workpiece, the outer sleeve shaft, the airbag shaft, and the airbag auxiliary shaft are driven independently vertically by the first driving mechanism, so that the outer sleeve shaft is inserted into the spherical workpiece, the bottom end of the airbag shaft is flush with the bottom end of the outer sleeve shaft, and the airbag extends from the bottom end of the outer sleeve shaft into the interior of the spherical workpiece. At this time, gas is introduced into the airbag auxiliary shaft, and the airbag can gradually expand and adhere tightly to the inner wall of the spherical workpiece through the suction cup outside the airbag. In this way, the airbag and the spherical workpiece are relatively fixed. After the support shaft is removed, it is convenient to perform all-round processing on the outside of the spherical workpiece. After the spherical workpiece is processed, the gas in the airbag is discharged through the airbag auxiliary shaft, and the outer sleeve shaft, the airbag shaft, and the airbag auxiliary shaft are driven independently vertically by the first driving mechanism, so that the outer sleeve shaft, the airbag shaft, and the airbag auxiliary shaft can be reset. The above structure ensures flexible contact between the processing device and the workpiece through direct contact between the airbag and the workpiece, making it suitable for workpieces with various shapes and inner surfaces, and avoiding damage to the fragile inner surface of the workpiece. Furthermore, the independent vertical movement of the outer sleeve shaft, airbag shaft, and airbag auxiliary shaft ensures effective expansion and contraction of the airbag structure, making it suitable for various industrial production scenarios such as assembly line operations.

[0024] Meanwhile, the spherical or irregularly shaped workpiece processing device of the present invention drives the airbag to rotate through the second driving mechanism. Since the outside of the airbag with multiple suction cups is firmly adsorbed and fixed to the inside of the spherical or irregularly shaped workpiece, it can drive the spherical or irregularly shaped workpiece to rotate, which facilitates the full surface processing of the spherical or irregularly shaped workpiece. Furthermore, when the workpiece is transferred to the next station after processing, a cleaning mechanism can be set up to clean the outside of the airbag during the rotation process.

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0048] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0049] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0050] The inventors of this invention have discovered that for spherical or irregularly shaped workpieces, the outer surface of the workpiece is not easy to clamp, making the processing of such workpieces quite difficult. Furthermore, when processing the entire outer surface of the workpiece is required, it is necessary to use only the inner surface for gripping and processing. For example, the workpiece can be supported by an internal support structure that extends into the workpiece. However, existing internal support structures have hard contact with the workpiece interior, which may cause damage to the internal support structure itself or the workpiece interior. Embodiments of this invention provide a processing apparatus for spherical or irregularly shaped workpieces, at least to solve the above-mentioned technical problems. The embodiments of this invention are illustrated using a spherical workpiece as an example.

[0051] Please refer to Figures 1-4 The workpiece processing device for spherical or irregular shapes provided in this embodiment of the invention includes a frame 100, an outer sleeve shaft 200, an airbag shaft 300, an airbag auxiliary shaft 400, an airbag 310, and a first drive mechanism 500. The outer sleeve shaft 200, airbag shaft 300, and airbag auxiliary shaft 400 are all hollow shafts, and are sequentially sleeved from the outside to the inside. The first drive mechanism 500 is mounted on the frame 100 and is connected to the outer sleeve shaft 200, airbag shaft 300, and airbag auxiliary shaft 400 respectively. The outer sleeve shaft 200, airbag shaft 300, and airbag auxiliary shaft 400 are connected and used to drive the outer sleeve shaft 200, airbag shaft 300, and airbag auxiliary shaft 400 to move independently vertically. The bottom ends of the outer sleeve shaft 200 and airbag shaft 300 are both open. The airbag 310 is connected to the bottom end of the airbag shaft 300. The interior of the airbag auxiliary shaft 400 is connected to the airbag 310, and the interior of the airbag auxiliary shaft 400 is used to introduce gas. The airbag 310 is used to support the interior of the spherical workpiece 900 when it extends from the bottom end of the outer sleeve shaft 200 and expands with introduced gas. The exterior of the airbag 310 is provided with multiple suction cups to adsorb the spherical workpiece 900.

[0052] The frame 100 has a frame structure. The first drive mechanism 500 is located on the top of the frame 100. The outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 all extend vertically. The outer sleeve shaft 200 is fitted onto the airbag shaft 300 and protects the airbag 310 when it is sent into the spherical workpiece 900. The bottom end of the outer sleeve shaft 200 is open and the top end is sealed. The bottom end of the airbag shaft 300 is fixedly connected to the airbag 310 by a clamp. The airbag auxiliary shaft 400 has an air inlet and an air outlet. The air inlet is connected to an external air compressor to facilitate air intake into the airbag 310, and the air outlet is connected to an external vacuum pump to facilitate air exhaust from the airbag 310. The bottom end of the airbag auxiliary shaft 400 is hemispherical with an opening at one end to facilitate inflation into the airbag 310 or deflation of the airbag 310. The top end of the airbag auxiliary shaft 400 is sealed.

[0053] It should be noted that the first drive mechanism 500 is used to drive the outer sleeve shaft 200, airbag shaft 300 and airbag auxiliary shaft 400 to move independently vertically, meaning that the first drive mechanism 500 can drive the outer sleeve shaft 200, airbag shaft 300 and airbag auxiliary shaft 400 to move independently vertically respectively.

[0054] Before machining the spherical workpiece 900, the first drive mechanism 500 drives the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 to move vertically downwards, so that the outer sleeve shaft 200 is inserted into the insertion interface of the spherical workpiece 900, the bottom end of the airbag shaft 300 is flush with the bottom end of the outer sleeve shaft 200, and the airbag 310 extends from the bottom end of the outer sleeve shaft 200 into the interior of the spherical workpiece 900. At this time, gas is introduced into the airbag auxiliary shaft 400. Since the airbag auxiliary shaft 400 is connected to the airbag 310, the gas... The airbag 310 can gradually expand and adhere to the inner wall of the spherical workpiece 900. The airbag 310 and the spherical workpiece 900 are relatively fixed, which facilitates the processing of the spherical workpiece 900. After the spherical workpiece 900 is processed, the gas in the airbag 310 is discharged through the airbag auxiliary shaft 400, and the first drive mechanism 500 drives the outer sleeve shaft 200, the airbag shaft 300 and the airbag auxiliary shaft 400 to move vertically upward until the outer sleeve shaft 200, the airbag shaft 300 and the airbag auxiliary shaft 400 contract.

[0055] In an optional embodiment, the first drive mechanism 500 includes a first drive cylinder 510, a second drive cylinder 520, and a third drive cylinder 530. The first drive cylinder 510 is connected to the outer sleeve shaft 200 via a first bracket 511, the second drive cylinder 520 is connected to the airbag shaft 300 via a second bracket 521, and the third drive cylinder 530 is connected to the airbag auxiliary shaft 400.

[0056] The piston rods of the first drive cylinder 510, the second drive cylinder 520, and the third drive cylinder 530 all extend vertically downwards. The piston rod of the first drive cylinder 510 is connected to the first bracket 511, which is connected to the outer sleeve shaft 200. The piston rod of the second drive cylinder 520 is connected to the second bracket 521, which is connected to the airbag shaft 300. The piston rod of the third drive cylinder 530 is directly connected to the airbag auxiliary shaft 400.

[0057] The outer sleeve shaft 200 is driven vertically by the first drive cylinder 510, the airbag shaft 300 is driven vertically by the second drive cylinder 520, and the airbag auxiliary shaft 400 is driven vertically by the third drive cylinder 530. This enables the independent vertical movement of the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400. Interference between the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 is not likely to occur. If the height of any one of the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 needs to be adjusted individually under actual working conditions, this can be achieved by simply activating the drive cylinder connected to it.

[0058] In an optional embodiment, a first bearing 210 is sleeved on the outer shaft 200, and a first bearing seat 220 is sleeved on the first bearing 210. The first bracket 511 is connected to the first bearing seat 220. A second bearing is sleeved on the airbag shaft 300, and a second bearing seat is sleeved on the second bearing. The second bracket 521 is connected to the second bearing seat. The piston rod of the third drive cylinder 530 is coaxially connected to the airbag auxiliary shaft 400.

[0059] By installing a first bearing 210 on the outer sleeve shaft 200, a second bearing on the airbag shaft 300, and connecting the piston rod of the third drive cylinder 530 to the airbag auxiliary shaft 400 coaxially, the coaxiality between the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 can be well guaranteed.

[0060] The first bearing 210 and the second bearing both include a deep groove bearing 211 and a thrust bearing 212.

[0061] It should be noted that the combined use of deep groove bearing 211 and thrust bearing 212 can overcome the influence of radial and axial forces on the shaft. Deep groove bearing 211 overcomes radial force, and thrust bearing 212 overcomes axial force, thereby improving the stability of the outer sleeve shaft 200 and airbag shaft 300 during movement.

[0062] Please combine Figure 5In an optional embodiment, the processing device further includes a second drive mechanism 600, which includes a first motor 610 and a gear set 620. The first motor 610 is mounted on the first bracket 511, and the output shaft of the first motor 610 extends horizontally and is connected to the gear set 620 for transmission. An outer gear 230 is sleeved on the outside of the outer shaft 200, and the gear set 620 is in transmission engagement with the outer gear 230. When the outer shaft 200 rotates, the airbag shaft 300 rotates synchronously with the outer shaft 200.

[0063] When the airbag 310 is inflated and adheres tightly to the inner wall of the spherical workpiece 900, the first motor 610 is activated. The first motor 610 drives the gear set 620 to rotate, which in turn drives the outer gear 230 to rotate. The outer gear 230 then drives the outer shaft 200 and the airbag shaft 300 to rotate synchronously. At this time, the airbag 310 can drive the spherical workpiece 900 to rotate, facilitating the processing of the spherical workpiece 900. The airbag auxiliary shaft 400 mainly provides the air pressure source for the expansion and contraction of the airbag 310 and controls the airbag 310 to maintain its slender shape when retracting into the outer shaft 200, preventing friction damage to the airbag 310. The airbag auxiliary shaft 400 itself does not rotate.

[0064] The gear set 620 includes two meshing bevel gears 621 and a driven gear 622. The output shaft of the first motor 610 extends horizontally and is connected to one of the bevel gears 621 for transmission. The other bevel gear 621 is coaxially connected to the driven gear 622, and the driven gear 622 meshes with the outer gear 230.

[0065] When the first motor 610 is started, the first motor 610 drives one of the bevel gears 621 to rotate, the other bevel gear 621 drives the driven gear 622 to rotate, the driven gear 622 drives the outer gear 230 to rotate, and the outer gear 230 drives the outer shaft 200 and the airbag shaft 300 to rotate synchronously. At this time, the airbag 310 can drive the spherical workpiece 900 to rotate, which is convenient for processing the spherical workpiece 900. The operation of the bevel gear 621 makes the transmission shaft shorter and the layout more reasonable.

[0066] In order to achieve synchronous rotation of the airbag shaft 300 and the outer sleeve shaft 200, a keyway 240 is provided on the outer sleeve shaft 200 and a flat key 320 is provided on the airbag shaft 300. The keyway 240 and the flat key 320 cooperate, and the flat key 320 can move along the length direction of the keyway 240. However, during the rotation of the outer sleeve shaft 200, due to the cooperation between the keyway 240 and the flat key 320, the airbag shaft 300 will rotate synchronously with the outer sleeve shaft 200.

[0067] Please combine Figure 6In an optional embodiment, the processing apparatus further includes a processing mechanism 700, which includes a fourth drive cylinder 710, a fifth drive cylinder 720, and a processing component 730 for processing a spherical workpiece 900. The fourth drive cylinder 710 is mounted on the frame 100, and the piston rod of the fourth drive cylinder 710 extends vertically upward and connects to the fifth drive cylinder 720. The piston rod of the fifth drive cylinder 720 extends horizontally and connects to the processing component 730.

[0068] In fact, the machining mechanism 700 is located on one side of the spherical workpiece 900, and the piston rod of the fifth drive cylinder 720 extends toward the spherical workpiece 900; the machined part 730 can be a turned part, a milled part, a planed part, a ground part, a polished part, a painted part, etc., depending on the actual working conditions.

[0069] The fourth drive cylinder 710 and the fifth drive cylinder 720 can drive the workpiece 730 to move up, down, left and right. Under the combined drive of the fourth drive cylinder 710 and the fifth drive cylinder 720, the workpiece 730 can simulate curved motion and move along the surface of the spherical workpiece 900 to complete the processing.

[0070] Please combine Figure 7 In an optional embodiment, the processing device further includes a cleaning mechanism 800, which includes a second motor 810, a sixth drive cylinder 820, and a cleaning tank 830 containing cleaning fluid. The second motor 810 is mounted on the frame 100, and the output shaft of the second motor 810 extends vertically upward and is connected to the sixth drive cylinder 820. The piston rod of the sixth drive cylinder 820 extends horizontally and is connected to the cleaning tank 830.

[0071] When it is necessary to clean the outside of the airbag 310, the position of the cleaning tank 830 is adjusted by the second motor 810 and the sixth drive cylinder 820 so that the cleaning tank 830 is located below the outer sleeve shaft 200. Then the airbag 310 is extended outside the outer sleeve shaft 200 and immersed in the cleaning liquid in the cleaning tank 830. Then the airbag 310 is rotated to complete the cleaning. After the cleaning is completed, the airbag 310 returns to the initial state.

[0072] In addition, a drain valve is installed at the bottom of the cleaning tank 830. After cleaning the airbag 310, the wastewater can be discharged by opening the drain valve. When it is necessary to add cleaning fluid to the cleaning tank 830, the cleaning fluid can be sourced from an external cleaning fluid tank or a CIP station.

[0073] Please combine Figure 8 , Figure 9In an optional embodiment, a support plate 110 is provided on the frame 100, a third bearing is provided inside the support plate 110, and a support shaft 120 for supporting the spherical workpiece 900 is provided on the support plate 110. The bottom of the support shaft 120 cooperates with the third bearing, which includes a deep groove bearing 211 and a thrust bearing 212.

[0074] It should be noted that the spherical workpiece 900 is detachably mounted on the support shaft 120; for example, the top of the support shaft 120 is provided with a spike, which fixes the spherical workpiece 900 when it pierces the spherical workpiece 900. The length of the spike is less than the thickness of the spherical workpiece 900 so as not to puncture the airbag 310.

[0075] The support plate 110 is movably mounted on the frame 100 in the horizontal direction. In fact, the frame 100 is equipped with a seventh drive cylinder 130. The piston rod of the seventh drive cylinder 130 extends horizontally and connects to the support plate 110. The bottom of the support plate 110 is equipped with a pulley 111, which slides with the frame 100 to reduce the friction generated when the support plate 110 moves. The shaft of the pulley 111 is equipped with a deep groove bearing to improve rotational stability. The seventh drive cylinder 130 can drive the support plate 110 and the support shaft 120 on the support plate 110 to move horizontally. This allows the support shaft 120 to move away from the spherical workpiece 900 when the airbag 310 fixes and lifts the spherical workpiece 900. This enables all-round processing of the outer surface of the spherical workpiece 900.

[0076] In addition, the processing device also includes a waste collection cart 140, which is located directly below the airbag. When the support plate 110 is removed, the support plate 110 no longer obstructs the waste collection cart 140, and the waste generated when processing the spherical workpiece 900 can fall and be collected in the waste collection cart 140.

[0077] The workpiece processing apparatus for spherical or irregular shapes provided in this embodiment of the invention has at least an initial state, an extended state, an expanded state, and a retracted state. Specifically, in the initial state, the outer sleeve shaft 200 is located outside the spherical workpiece 900, the airbag shaft 300 and the airbag 310 are retracted into the outer sleeve shaft 200, and the airbag auxiliary shaft 400 extends into the airbag 310; in the extended state, the outer sleeve shaft 200 is inserted into the insertion interface of the spherical workpiece 900, the bottom end of the airbag shaft 300 is approximately flush with the bottom end of the outer sleeve shaft 200, the airbag 310 extends into the interior of the spherical workpiece 900, and the airbag auxiliary shaft 400 extends into the airbag 310; in the expanded state, the airbag auxiliary shaft 400 receives pressure from the air inlet. Air is compressed, and the airbag 310 expands to the inner wall of the spherical workpiece 900. The suction cup on the outer surface of the airbag 310 adheres tightly to it and maintains a certain pressure, thus firmly fixing the spherical workpiece 900. Then the support shaft 120 is removed, which allows for all-round processing of the outer surface of the spherical workpiece 900. The bottom end of the airbag auxiliary shaft 400 retracts to be roughly flush with the bottom end of the airbag shaft 300. In the retracted state, the airbag auxiliary shaft 400 extends into the airbag 310, and a negative pressure is generated at the air outlet of the airbag auxiliary shaft 400, causing the airbag 310 to expel air. Subsequently, the airbag auxiliary shaft 400 and the airbag shaft 300 retract synchronously to ensure that the airbag 310 returns to the outer sleeve shaft 200 in a slender shape.

[0078] In summary, this invention provides a processing device for spherical or irregularly shaped workpieces. Before processing the spherical workpiece 900, the first driving cylinder 510, the second driving cylinder 520, and the third driving cylinder 530 respectively drive the outer sleeve shaft 200, the airbag shaft 300, and the airbag auxiliary shaft 400 to move vertically downwards, so that the outer sleeve shaft 200 is inserted into the insertion interface of the spherical workpiece 900, the bottom end of the airbag shaft 300 is flush with the bottom end of the outer sleeve shaft 200, and the airbag 310 extends from the bottom end of the outer sleeve shaft 200 into the interior of the spherical workpiece 900. At this time, gas is introduced into the airbag auxiliary shaft 400. Since the airbag auxiliary shaft 400 is connected to the airbag 310, the airbag 310 can gradually inflate and adhere tightly to the inner wall of the spherical workpiece 900. 310 is fixed relative to the spherical workpiece 900. During the processing of the spherical workpiece 900, the first motor 610 and gear set 620 can horizontally rotate the spherical workpiece 900 to an appropriate angle, while the fourth drive cylinder 710 and the fifth drive cylinder 720 can make the workpiece 730 contact the outer surface of the spherical workpiece 900 to complete the processing action. After the spherical workpiece 900 is processed, the gas in the airbag 310 is discharged through the airbag auxiliary shaft 400, and the first drive cylinder 510, the second drive cylinder 520 and the third drive cylinder 530 are used to drive the outer sleeve shaft 200, the airbag shaft 300 and the airbag auxiliary shaft 400 to move vertically upward, until the outer sleeve shaft 200, the airbag shaft 300 and the airbag auxiliary shaft 400 retract.
