Description

Technical Field

[0001] The present invention relates to the technical field of industrial robots, and particularly relates to an industrial robot for assisting production of a numerical control lathe and a using method thereof. Background Art

[0002] An industrial robot is defined as "a manipulator that is automatically controlled, reprogrammable, multi-purpose, and can be programmed for more than 3 axes. It can be fixed or mobile and is used in industrial automation applications". The manipulator is defined as "a machine whose mechanism is usually composed of a series of articulated or relatively sliding members. It usually has several degrees of freedom to grasp or move an object". Therefore, an industrial robot can be understood as a mechatronic device with anthropomorphic arm, wrist, and hand functions; it can move any object or tool according to the time-varying requirements of the spatial pose, so as to complete the operation requirements of a certain industrial production.

[0003] In current numerical control lathe production, manual clamping or unloading is carried out. Manual clamping relies on multiple skilled workers to operate in shifts, increasing the long-term labor input cost. Clamping errors may lead to workpiece scrapping or tool damage, indirectly increasing the production cost. Moreover, the parts have just undergone processing on the numerical control lathe and have a temperature, and it takes time to cool down. The dust on the surface of the parts cannot be cleaned. The dust may cause measurement and processing errors, affecting the dimensional accuracy of the parts, resulting in an increase in roughness, affecting the appearance and performance. The dust will accelerate tool wear, shorten the service life, and increase the cost. In addition, the dust on the surface of the parts after processing may affect the part fit, leading to difficult assembly or abnormal functions, and will affect the adhesion of the coating or plating, resulting in blistering or peeling. There is also a risk of equipment failure when dust enters the equipment interior, and manual cleaning of the part surface is required after processing. Summary of the Invention

[0014] Through the above technical solution, in order to facilitate removing the parts processed on the numerical control lathe first and then replacing the unprocessed parts, the rotating disk rotates under the action of the switching motor, so as to drive the switching of the two clamping mechanisms.

[0015] Preferably, the cleaning mechanism includes a connecting frame fixedly installed on the upper surface of the mounting plate. A conveying pipeline with a rotary joint is fixedly installed on the outer surface of the connecting frame. One end of a conveying pipeline is fixedly installed with an air pump.

One end of the total air inlet pipeline is fixedly communicated with an air inlet branch pipeline through a connecting groove. One end of the total water inlet pipeline is fixedly communicated with a water inlet branch pipeline through a connecting groove.

[0016] Through the above technical solution, the air pump can pump air, which can cool the processed parts or clean the external dust of the unprocessed parts being clamped to prevent the dust from affecting the processing. The air intake main pipeline can divide the air into the air intake sub-pipelines, so that the conveyed air can be divided and selectively conveyed to the required end. The water intake main pipeline can convey the coolant to the water intake sub-pipelines. The connection groove of the water intake main pipeline is inside the air intake main pipeline, which is convenient for the air to be cooled when passing through the water intake sub-pipelines.

[0017] Preferably, a clamping outer shell is fixedly installed on the outer surface of the connection groove of the air intake sub-pipeline through a bracket. The inner wall of the clamping outer shell is rotatably connected with a clamping gear ring through a bearing. A moving block with a rack is slidably inserted into the inner wall of the clamping outer shell. The inner wall of the clamping outer shell is rotatably connected with a transmission gear through a bearing. The transmission gear meshes with the clamping gear ring and the rack of the moving block respectively. A clamping motor is fixedly installed on the outer surface of the clamping outer shell. One end of the output shaft of the clamping motor meshes with one of the transmission gears. One end of the moving block is rotatably connected with a clamping roller. One end of the clamping roller is rotatably connected with a rotating component. The other end of the rotating component is rotatably connected to the outer surface of the clamping outer shell through a bearing. One end of the synchronous pulley of the rotating component is fixedly installed with a rotating gear. A rotating gear ring is rotatably connected to the outer surface of the clamping outer shell. The rotating gear ring meshes with the rotating gear. A rotating motor is fixedly installed on the outer surface of the clamping outer shell. One end of the output shaft of the rotating motor meshes with the rotating gear ring through a gear.

[0018] Through the above technical solution, the rotation of one transmission gear can drive the rotation of the clamping gear ring. The transmission of the clamping gear ring can drive multiple transmission gears to rotate synchronously, thereby driving the moving blocks distributed in an annular array to move relatively or in the opposite direction. The clamping of the parts can be completed by the movement of the clamping rollers. The rotating component is composed of a synchronous belt and a synchronous pulley. The synchronous pulley can drive the synchronous belt to rotate after rotating through the rotating gear, and the synchronous belt can drive the clamping rollers to rotate, so as to drive the parts to rotate, which is convenient for uniform heat dissipation of the parts and at the same time keeps the cleaning uniform.

[0019] Preferably, an adjusting sleeve is fixedly installed on the outer surface of the clamping housing. An adjusting rod with a sealing ring and rollers is slidably inserted into the inner wall of the adjusting sleeve. The rollers of the adjusting rod are in contact with the outer surface of the synchronous belt of the rotating member. A connecting spring is sleeved on the outer surface of the adjusting rod. One end of the connecting spring is fixedly installed on the inner wall of the adjusting sleeve. One end of the adjusting sleeve is fixedly communicated with one end of the water inlet branch pipe through a connecting pipe. One end of the air inlet branch pipe is fixedly installed with an annular pipe. One end of the annular pipe is fixedly communicated with the inner wall of the clamping housing through a connecting pipe. Air outlet holes are formed in the outer surface of the clamping housing.

[0020] Through the above technical solution, in order to facilitate the movement of the moving block, the synchronous belt on the rotating member is squeezed by the adjusting rod to adjust the tension of the synchronous belt, so that the rotating member can move in cooperation with the movement of the moving block. In order to drive the adjusting rod to move in the adjusting sleeve, the water conveyed through the water inlet branch pipe is used to adjust the pressure on the adjusting rod. In order to dissipate heat or clean the parts, by connecting the annular pipe and the air inlet branch pipe, gas can be conveyed into the clamping housing. Through the air outlet holes on the clamping housing, heat can be dissipated from the parts or dust on the surface can be removed.

[0021] Preferably, a cleaning sleeve is fixedly installed on the inner wall of the clamping housing. An inflatable airbag with a spring is fixedly installed on the inner wall of the cleaning sleeve. One end of the inflatable airbag is fixedly communicated with the inner wall of the annular pipe through a connecting pipe. A cleaning brush is slidably inserted into the inner wall of the cleaning sleeve.

[0022] Through the above technical solution, in order to remove dust and debris on the surface of the parts, after the annular pipe is inflated, gas can enter the inflatable airbag through the connecting pipe. After the inflatable airbag expands, it pushes the cleaning brush, so that the cleaning brush can contact the parts. As the parts rotate, the outer surface dust of the parts can be fully cleaned.

[0023] Preferably, the clamping mechanism includes a clamping hydraulic cylinder. The outer surface of the clamping hydraulic cylinder is fixedly installed on the outer surface of the connecting groove of the air inlet branch pipe. One end of the piston rod of the clamping hydraulic cylinder is fixedly installed with a clamping jaw.

[0024] Through the above technical solution, in order to clamp and convey the unprocessed parts on the vibrating feeding tray or the parts processed on the CNC lathe into the clamping rollers, the clamping hydraulic cylinder is used to push the clamping jaw to move closer to the parts.

[0025] A usage method of an industrial robot for assisting the production of a CNC lathe proposed by the present invention includes the following steps:

[0026] S1: When machining cylindrical parts, after the vibrating feeding tray is started, the parts are conveyed. After the clamping hydraulic cylinder is started, it pushes the clamping jaws through the clamping housing to contact the parts on the vibrating feeding tray. Then, the clamping jaws start to clamp the parts and retract. The clamped parts are located between the clamping rollers. After the clamping motor is started, it drives the rotation of a transmission gear. Through the transmission of the rotation of the transmission gear by the clamping gear ring, the rotation of the other transmission gears is driven. The transmission gears drive the moving block to move. At the same time, after the suction water pump is started, it sucks the water in the suction conveying pipeline. The control valve on one side of the total water inlet pipeline is closed, and the control valve on the other side is opened. The water in the connected adjusting sleeve enters the conveying pipeline through the water inlet branch pipeline and is then conveyed into the water storage tank. After the water pressure in the adjusting sleeve decreases, the adjusting rod is reset under the action of the connecting spring, reducing the extrusion of the synchronous belt in the rotating component, adjusting the tension of the synchronous belt, so that the synchronous belt can cooperate with the movement of the moving block. The clamping rollers of the moving block contact the parts to complete the clamping of the parts, and the clamping jaws are reset after contacting and clamping the parts.

[0027] S2: After the air pump is started, it sucks air into the conveying pipeline. The conveying pipeline conveys the gas into the total air inlet pipeline. Through the total air inlet pipeline, the gas can be conveyed to the air inlet branch pipeline on the clamped parts. The gas in the air inlet branch pipeline enters the annular pipeline and is then conveyed into the clamping housing. The gas blows the parts through the air outlet holes. At the same time, the gas in the air inlet branch pipeline enters the cleaning sleeve and restarts the inflatable airbag. After the inflatable airbag expands, it squeezes the cleaning brush, so that the cleaning brush contacts the parts.

[0028] S3: At the same time, after the rotating motor is started, it drives the rotation of the rotating gear ring through the gear, then drives the rotation of the rotating gear on the rotating component, and then drives the clamping rollers to rotate. The clamping rollers drive the parts to rotate. After the dust removal of the part surface is completed, the rotating motor stops starting, the air pump stops conveying gas, and after the gas in the inflatable airbag flows out, the spring in the inflatable airbag resets the inflatable airbag.

[0029] S4: After the telescopic hydraulic cylinder on the support plate is started, it pushes the push plate. The push plate drives the moving plate to move. The moving gear on the synchronous wheel in the transmission component on the push plate meshes with the moving rack, driving the transmission component to rotate. The synchronous belt in the transmission component drives the moving plate to be able to move, driving the mounting plate to move closer to the CNC lathe. At the same time, the rollers on the sliding rod move on the support inclined plate. When leaving the inclined plate of the support inclined plate, the mounting plate is reset under the action of the reset spring. The movement of the moving plate drives the mounting plate to move into the interior of the CNC lathe. The sliding rod on the mounting plate pushes the mounting plate to move, so that the clamped parts are close to the clamping component of the CNC lathe. After the clamping hydraulic cylinder is started, the clamping jaws clamp the parts and convey them to the clamping component of the CNC lathe, and the parts are clamped by the clamping component.

[0030] S5: When it is necessary to unload the parts processed on the CNC lathe, switch on the motor. Through the transmission of the gears, drive the rotating disc on the support seat to rotate, complete the switching of the two clamping shells. The rotary joint facilitates the rotation of the intake main pipeline and the water inlet main pipeline driven by the rotating disc. After the clamping hydraulic cylinder is started, the clamping claws can clamp the parts on the CNC lathe and unload the processed parts. The processed parts can enter the clamping shell, and the clamping rollers clamp the parts. The air pump is started, and the pumped gas can be cooled by blowing the water inlet branch pipeline containing the coolant. The air outlet holes transport the gas to the outer surface of the parts to complete the cooling of the parts. At the same time, the cleaning brush cleans the parts to reduce the residue of debris after processing.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. By setting the telescopic device, the clamped parts can be transported. In order to facilitate the transportation of the parts into the CNC lathe and reduce the occupied space of the industrial robot, while the telescopic hydraulic cylinder drives the push plate to move, the moving gear on the transmission component can move on the moving rack and then drive the transmission component to rotate, and at the same time drive the moving plate to move, realizing the function of multi-stage telescoping, so as to quickly complete the transportation of the parts.

[0033] 2. By setting the clamping device, the parts can be clamped and transported. Through the movement of the moving block, the clamping rollers can be driven to move and then contact the parts to complete the clamping of the parts. By adjusting the rod to squeeze the synchronous belt on the rotating component, the tension of the synchronous belt is adjusted so that the rotating component can move in cooperation with the movement of the moving block. In order to drive the adjusting rod to move in the adjusting sleeve, the water transported through the water inlet branch pipeline adjusts the pressure on the adjusting rod, so as to complete the clamping of the parts and drive the parts to rotate, solving the problem that in the existing CNC lathe production, manual clamping or unloading is carried out. Manual clamping relies on multiple skilled workers to work in shifts, and the long-term labor input cost increases.

[0034] 3. By setting up a cleaning mechanism, the surface of the parts can be cleaned or cooled. The air pump can extract gas, which can cool the processed parts or clean the external dust of the unprocessed parts being clamped, preventing dust from affecting the processing. Through the main air inlet pipe, the gas can be diverted into the branch air inlet pipes, enabling the transported gas to be diverted and selectively transported to the required end. The main water inlet pipe can transport the coolant into the branch water inlet pipes. The connection slot of the main water inlet pipe is inside the main air inlet pipe, facilitating the cooling of the gas when it passes through the branch water inlet pipes. The cooled gas is blown towards the parts through the air outlet holes, thereby being able to cool the surface of the parts, solving the problems that in the existing numerical control lathe production, the parts just processed by the numerical control lathe have temperature and need time to cool down, the dust on the surface of the parts cannot be cleaned, the dust may cause measurement and processing errors, affecting the dimensional accuracy of the parts, resulting in an increase in roughness, affecting the appearance and performance, the dust will accelerate the tool wear, shorten the service life, increase the cost, and the dust on the surface of the processed parts may affect the fit of the parts.

One end of the piston rod of the clamping hydraulic cylinder 9 is fixedly installed with a clamping jaw 91.

[0064] A method for using an industrial robot for assisting the production of a numerically controlled lathe 1 proposed by the present invention includes the following steps:

[0065] S1: When machining cylindrical parts is required, after the vibrating feeding tray 11 is started, the parts are conveyed. After the clamping hydraulic cylinder 9 is started, it pushes the clamping jaws 91 through the clamping housing 7 to contact the parts on the vibrating feeding tray 11. Then, the clamping jaws 91 are started to clamp the parts and then retract. The clamped parts are located between the clamping rollers 75. After the clamping motor 74 is started, it drives the rotation of a transmission gear 73. Through the transmission of the rotation of the transmission gear 73 by the clamping gear ring 71, the rotation of the remaining transmission gears 73 is driven. The transmission gears 73 drive the movement of the moving block 72. At the same time, after the suction water pump 63 is started, it sucks the water in the suction conveying pipeline 61. The control valve on one side of the total water inlet pipeline 66 is closed, and the control valve on the other side is opened. The water in the connected adjusting sleeve 8 enters the conveying pipeline 61 through the water inlet branch pipeline 69 and is then conveyed into the water storage tank 65. After the water pressure in the adjusting sleeve 8 decreases, the adjusting rod 81 is reset under the action of the connecting spring 82, reducing the extrusion of the synchronous belt in the rotating component 76, adjusting the tension of the synchronous belt, so that the synchronous belt can cooperate with the movement of the moving block 72. The clamping rollers 75 of the moving block 72 contact the parts to complete the clamping of the parts. After the clamping jaws 91 contact and clamp the parts, they are reset.

[0066] S2: After the air pump 62 is started, it sucks air into the conveying pipeline 61. The conveying pipeline 61 conveys the gas into the total air inlet pipeline 67. Through the total air inlet pipeline 67, the gas can be conveyed to the air inlet branch pipeline 68 on the clamped parts. The gas in the air inlet branch pipeline 68 enters the annular pipeline 83 and is then conveyed into the clamping housing 7. The gas blows the parts through the air outlet holes 84. At the same time, the gas in the air inlet branch pipeline 68 enters the cleaning sleeve 85 and restarts the inflatable airbag 86. After the inflatable airbag 86 expands, it squeezes the cleaning brush 87, making the cleaning brush 87 contact the parts.

[0067] S3: At the same time, the rotating motor 79 is started. After driving the rotation of the rotating gear ring 78 through the gear, it drives the rotation of the rotating gear 77 on the rotating component 76, and then drives the rotation of the clamping rollers 75. The clamping rollers 75 drive the parts to rotate. After the dust removal on the surface of the parts is completed, the rotating motor 79 stops starting. The air pump 62 stops conveying gas. After the gas in the inflatable airbag 86 flows out, the spring in the inflatable airbag 86 resets the inflatable airbag 86.

[0068] S4: After the telescopic hydraulic cylinder 31 on the support plate 3 is started, it will push the push plate 32. After the push plate 32 is pushed, the push plate 32 drives the moving plate 33 to move. After the moving gear 35 on the synchronous wheel in the transmission component 34 on the push plate 32 meshes with the moving rack 36, it drives the transmission component 34 to rotate. The synchronous belt in the transmission component 34 drives the moving plate 33 to be able to move, driving the mounting plate 43 to move closer to the CNC lathe 1. At the same time, the rollers on the sliding rod 44 move on the support inclined plate 4. When leaving the inclined plate of the support inclined plate 4, the mounting plate 43 is reset under the action of the return spring 42. After the moving plate 33 moves to drive the mounting plate 43 into the interior of the CNC lathe 1, the sliding rod 44 on the mounting plate 43 pushes the mounting plate 43 to move, so that the clamped part is close to the clamping component of the CNC lathe 1. After the clamping hydraulic cylinder 9 is started, the clamping jaws 91 clamp the part and convey it to the clamping component of the CNC lathe 1, and the part is clamped by the clamping component.

[0069] S5: When it is necessary to unload the parts processed on the CNC lathe 1, the switching motor 5 is started. Through the transmission of the gears, the rotating disk 52 on the support seat 51 is driven to rotate, completing the switching of the two clamping housings 7. The rotary joint facilitates the rotation of the intake main pipeline 67 and the water intake main pipeline 66 driven by the rotating disk 52. After the clamping hydraulic cylinder 9 is started, the clamping jaws 91 can clamp the parts on the CNC lathe 1 and unload the processed parts. The processed parts can enter the clamping housing 7, and the clamping rollers 75 clamp the parts. The air pump 62 is started, and the sucked air can be cooled by blowing the water intake sub-pipeline 69 containing the coolant. The air outlet holes 84 convey the air to the outer surface of the parts to complete the cooling of the parts. At the same time, the cleaning brush 87 cleans the parts to reduce the residue of the chips after processing.

[0070] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
