Description

Technical Field

[0001] This utility model relates to the field of parts assembly and testing technology, and more specifically, to a pressing device for internal parts of an automobile engine. Background Technology

[0002] An engine is an energy conversion mechanism that converts the thermal energy of gasoline (diesel) or natural gas into mechanical energy by burning the gas in a sealed cylinder, causing the gas to expand and push the piston to do work. This provides power for the car to move and is related to the car's power, economy, and environmental performance.

[0003] Currently, during the production of automobile engines, sealing components and steel ball components are press-fitted internally to ensure sealing performance and the transmission of mechanical power during operation. The sealing components improve the sealing performance of the automobile engine, and the steel balls reduce the friction generated during engine operation, enabling the automobile engine to maintain good mechanical transmission performance. However, existing pressing equipment typically uses multiple machines to press different components separately when pressing sealing components and steel ball components into automobile engines. Each pressing machine requires a worker to assist in the operation, which not only results in low automation but also slow pressing speed. Utility Model Content

[0060] In this embodiment, the car engine housing is placed on the positioning fixture 3 at one end of the chain conveyor 2. The chain conveyor 2 drives the positioning fixture 3 to transport the car engine housing. The car engine housing first moves to correspond with the sealing pressing mechanism 7. The sealing component is placed on the feeding mechanism 4. The picking mechanism 5 picks up the sealing component and places it on the positioning assembly mechanism 6 for positioning and assembly. Then, the assembled sealing component is picked up and placed on the sealing pressing mechanism 7. The sealing pressing mechanism 7 first positions the car component and then presses the sealing component to fix it inside, improving the sealing effect. After the sealing component is pressed, the chain conveyor 2 drives the positioning fixture 3 to move the sealing component to correspond with the steel ball pressing mechanism 8. The steel ball pressing mechanism 8 presses the steel balls into the car engine housing. To improve the mechanical transmission effect of the automobile engine, after the steel balls are pressed, the chain conveyor 2 moves the automobile engine housing to the position corresponding to the transfer module 9 via the positioning fixture 3.

The marking machine 12 marks the products and the barcode scanner 13 scans the products to record product information. Finally, the pressed products are placed on the discharge conveyor 14 and discharged.

[0061] Specifically, the feeding mechanism 4 includes two turntables 41, both of which are fixedly connected to the machine base 1. Each of the two turntables 41 is fixedly connected to a set of connecting rods 42, and each of the two sets of connecting rods 42 is slidably connected to a set of lifting blocks 43. The machine base 1 is fixedly connected to two lifting modules 44, and the two lifting modules 44 correspond to the two sets of lifting blocks 43 respectively.

[0062] In this embodiment, aluminum rings and sealing rings are placed on the two sets of connecting rods 42 respectively. The two turntables 41 drive the two sets of connecting rods 42 to rotate, so that the connecting rods 42 with aluminum rings and sealing rings correspond to the material picking mechanism 5 in sequence. The two lifting modules 44 push the two lifting blocks 43 respectively to raise the aluminum rings and sealing rings on the connecting rods 42 for material feeding, so that the material picking mechanism 5 can grab them.

[0063] Specifically, the material handling mechanism 5 includes a robotic arm 51, which is fixedly connected to the machine base 1. The robotic arm 51 is equipped with a vertical cylinder gripper 52, an external support clamp 53, and a horizontal cylinder gripper 54. The vertical cylinder gripper 52 and the external support clamp 53 correspond to two sets of connecting rods 42 respectively.

[0064] In this embodiment, the robotic arm 51 moves the vertical gripper 52, the external support clamp 53, and the horizontal gripper 54 of the cylinder, so that the vertical gripper 52 grips the aluminum ring, the external support clamp 53 opens and grips the sealing ring, and after the aluminum ring and the sealing ring are gripped, they are placed on the positioning and assembly mechanism 6 for positioning and assembly. After the assembly is completed, the robotic arm 51 drives the external support clamp 53 to take out the sealing accessories and place them on the sealing and pressing mechanism 7.

[0065] Specifically, the positioning assembly mechanism 6 includes a fixed seat 61, which is fixedly connected to the positioning assembly mechanism 6. A positioning seat 62 is rotatably connected to the fixed seat 61, and the positioning seat 62 corresponds to the cylinder vertical gripper 52, the external support clamp 53, and the cylinder horizontal gripper 54. A telescopic cylinder 63 is movably hinged to the fixed seat 61 via a hinge shaft, and the output end of the telescopic cylinder 63 is movably hinged to the positioning seat 62 via a hinge shaft.

[0066] In this embodiment, the robotic arm 51 uses the vertical gripper 52 to position the aluminum ring it has grasped onto the positioning seat 62. The external support clamp 53 then uses the gripped sealing ring to fit onto the aluminum ring to complete the assembly. The telescopic cylinder 63 pushes the positioning seat 62 to rotate 90 degrees within the fixed seat 61, so that the assembled sealing component corresponds to the horizontal gripper 54. The robotic arm 51 moves the horizontal gripper 54 to grip the sealing component and place it onto the sealing pressing mechanism 7.

[0067] Specifically, the sealing and pressing mechanism 7 includes a support frame 71, which is fixedly connected to the machine base 1. A positioning cylinder 72 is fixedly connected to the support frame 71. A positioning pressure plate 73 is fixedly connected to the output end of the positioning cylinder 72, and the positioning pressure plate 73 is slidably connected to the support frame 71 and corresponds to multiple positioning fixtures 3. A detection camera 74 is fixedly connected to the machine base 1 and corresponds to the cylinder horizontal gripper 54. A side pressing cylinder 75 is fixedly connected to the machine base 1. A pressing head 76 is fixedly connected to the output end of the side pressing cylinder 75 and is located on one side of the detection camera 74 and corresponds to multiple positioning fixtures 3.

[0068] In this embodiment, the chain conveyor 2 moves the car engine housing to the lower side of the positioning plate 73 via the positioning fixture 3. The positioning cylinder 72 controls the positioning plate 73 to move up and down on the support frame 71. The positioning plate 73 presses and fixes the car engine housing on the positioning fixture 3, corresponding to the pressing head 76. The robotic arm 51 controls the cylinder horizontal gripper 54 to put the sealing accessory on the pressing head 76. When the detection camera 74 detects the sealing accessory, the side pressing cylinder 75 pushes the pressing head 76 to press the sealing accessory into the car engine housing.

[0069] Specifically, the steel ball pressing mechanism 8 includes a feeding box 81, which is fixedly connected to the machine base 1. A support platform 82 is fixedly connected to the machine base 1. A feeding funnel 83 is slidably inserted into the support platform 82, and the feeding box 81 corresponds to the feeding funnel 83. A vibrating cylinder 84 is fixedly connected to the support platform 82, and the conveying end of the vibrating cylinder 84 is fixedly connected to the feeding funnel 83. A storage block 85 is fixedly connected to the support platform 82, and the storage block 85 communicates with the feeding funnel 83 through a pipe. A cylinder is installed inside the storage block 85. The misalignment module 86 has a fixed frame 87 fixedly connected to the machine base 1. A feeding block 89 is fixedly connected to the fixed frame 87, and the feeding block 89 is connected to the storage block 85 through a pipe and corresponds to multiple positioning fixtures 3.

A side positioning cylinder 810 is fixedly connected to the machine base 1, and a positioning head 811 is fixedly connected to the output end of the side positioning cylinder 810, and the positioning head 811 corresponds to multiple positioning fixtures 3.

[0070] In this embodiment, after the sealing fittings are press-fitted onto the car engine housing, the positioning cylinder 72 moves the positioning plate 73 upward to release the fixation of the car engine housing. The chain conveyor 2 continues to move the car engine housing on the positioning fixture 3, causing the car engine housing to move to the lower side of the feeding block 89. The side positioning cylinder 810 pushes the positioning head 811 to position the car engine housing from the side. Steel balls are placed in the feeding box 81 and flow into the feeding funnel 83. The feeding funnel 83 transports the steel balls to the storage block 85 through a pipe. During the feeding process, the vibrating cylinder 84 controls the lifting and lowering of the feeding funnel 83, causing the steel balls in the feeding funnel 83 to vibrate and prevent blockage. After the steel balls enter the storage block 85, they are picked up by the cylinder feeding module 86. The cylinder feeding module 86 pushes the steel balls so that only one steel ball can be delivered into the discharge block 89 each time through the pipeline, preventing too many steel balls from affecting the pressing. After entering the discharge block 89, the steel balls fall into the car engine housing. The pressing cylinder 88 moves the output end down through the discharge block 89, pressing the steel balls into the car engine housing.

[0071] Specifically, the testing mechanism 10 includes a mounting frame 101, which is fixedly connected to the machine base 1. A receiving cylinder module 102 is fixedly connected inside the mounting frame 101.

[0072] In this embodiment, the transfer module 9 picks up the pressed-up car engine housing from the positioning fixture 3. The receiving cylinder module 102 pushes the receiving fixture 103 to extend outward from the mounting bracket 101 to correspond with the transfer module 9. The transfer module 9 places the car engine housing on the receiving fixture 103. Then, the receiving cylinder module 102 controls the receiving fixture 103 to reset, so that the car engine housing corresponds with the positioning plate assembly 105. The positioning cylinder module 104 controls the positioning plate assembly 105 to move down and press and position the car engine housing. The detection cylinder module 106 pushes the intake detection head 107 into the car engine housing. The intake detection head 107 is connected to an external air source and delivers gas into the car engine housing for air tightness testing.

[0073] Working principle: During the press-fitting of automotive engine housing parts, the automotive engine housing is placed on the positioning fixture 3 via the feeding end of the chain conveyor 2. The chain conveyor 2 drives the positioning fixture 3 to move the automotive engine housing to align with the positioning pressure plate 73. The positioning cylinder 72 controls the positioning pressure plate 73 to move up and down on the support frame 71. The positioning pressure plate 73 presses and fixes the automotive engine housing on the positioning fixture 3 to align with the press-fitting head 76. Two turntables 41 drive two sets of connecting rods 42 to rotate, aligning the connecting rods 42 with aluminum rings and sealing rings with the robotic arm 51. Two lifting modules 44 push two lifting blocks 43 respectively, causing the aluminum rings and sealing rings on the connecting rods 42 to rise and feed material to the cylinder vertical gripper 52 and the external support fixture 53. The robotic arm... The robotic arm 51 moves the vertical gripper 52, the outer support clamp 53, and the horizontal gripper 54, causing the vertical gripper 52 to grasp the aluminum ring and the outer support clamp 53 to open and grasp the sealing ring. The robotic arm 51 positions the grasped aluminum ring on the positioning seat 62 via the vertical gripper 52, and then uses the outer support clamp 53 to place the grasped sealing ring onto the aluminum ring to complete the assembly. The telescopic cylinder 63 pushes the positioning seat 62 to rotate 90 degrees within the fixed seat 61, aligning the assembled sealing component with the horizontal gripper 54. The robotic arm 51 moves the horizontal gripper 54 to grasp and place the sealing component onto the pressing head 76. When the inspection camera 74 detects the sealing component on the pressing head 76, the side pressing cylinder 75 pushes the pressing head 76 to press the sealing component into the vehicle. Inside the engine housing, after the sealing components are press-fitted, the positioning cylinder 72 moves the positioning plate 73 upward to release the fixation of the car engine housing. The chain conveyor 2 continues to move the car engine housing on the positioning fixture 3, causing the car engine housing to move to the lower side of the feeding block 89. The side positioning cylinder 810 pushes the positioning head 811 to position the car engine housing from the side. Steel balls are placed in the feeding box 81 and flow into the feeding funnel 83. The feeding funnel 83 transports the steel balls to the storage block 85 through the pipe. During the transportation process, the vibrating cylinder 84 controls the raising and lowering of the feeding funnel 83, causing the steel balls in the feeding funnel 83 to vibrate, ensuring that the steel balls smoothly enter the storage block 85. After entering the storage block 85, the steel balls are received by the cylinder feeding module 86. Module 86 pushes a steel ball so that only one steel ball can be delivered into the discharge block 89 at a time through the pipe. After entering the discharge block 89, the steel ball falls into the car engine housing. The upper pressing cylinder 88 moves the output end downward through the discharge block 89, pressing the steel ball into the car engine housing. After the steel ball is pressed, the upper pressing cylinder 88 controls the output end to reset, and the side positioning cylinder 810 controls the positioning head 811 to reset and cancel the positioning of the car engine housing. The chain conveyor 2 moves the car engine housing to the position corresponding to the transfer module 9 through the positioning fixture 3. The transfer module 9 grabs the pressed car engine housing from the positioning fixture 3. The receiving cylinder module 102 pushes the receiving fixture 103 to extend outward from the mounting bracket 101 to correspond to the transfer module 9.The transfer module 9 places the car engine housing onto the receiving fixture 103. Then, the receiving cylinder module 102 controls the receiving fixture 103 to reset, aligning the car engine housing with the positioning plate assembly 105. The positioning cylinder module 104 controls the positioning plate assembly 105 to move downwards, pressing and positioning the car engine housing. The detection cylinder module 106 pushes the intake detection head 107 into the car engine housing. The intake detection head 107 delivers gas into the car engine housing through an external air source for an airtightness test. After the airtightness test is completed, the transfer module 9 again grabs the car engine housing and moves it, placing defective products into the discharge chute 11 for outflow. Normal products are moved onto the discharge conveyor 14. As the products move onto the discharge conveyor 14, they pass sequentially through the marking machine 12 and the barcode scanner 13. The marking machine 12 marks the products, and the barcode scanner 13 scans the products to record product information. Finally, the pressed products are placed on the discharge conveyor 14 for outflow.
