[0016] The present application provides a frame assembly line with detection function, which has the following beneficial effects.

[0017] 1. In the process of using this invention, under the push of the cylinder, the outer pressure plate drives the pressure head at the bottom of the piston cylinder to first contact the top of the head tube of the frame body. On the one hand, the steel cup body at the top is pressed into the top opening of the head tube, and on the other hand, the steel cup body at the bottom is pressed into the bottom opening of the head tube. During this process, the oil in the oil chamber is injected into the steel cup body at the bottom through the open conical opening. After that, the inner pressure plate injects the oil in the piston cylinder into the steel cup body at the top through the oil injection hole reserved on the pressure head. Thus, the pressing and oiling process of the front head tube of the frame body is completed. Under the thrust provided by the cylinder, this application sequentially completes the three processes of double feeding of the steel cup body, double pressing of the front head tube of the frame body, and double oiling of the upper and lower steel cup bodies.

[0018] 2.

The push block is pushed out by the cooperation of the top conical surface of the drive groove with the outer inclined surface of the recess, and the push block is retracted by the cooperation of the bottom conical surface of the drive groove with the inner inclined surface of the recess. This enables the double automatic supply of the upper and lower steel cup bodies during the descent of the outer pressure plate. This application links the pressing process of the outer pressure plate driven by the cylinder with the double feeding of the steel cup bodies. It can not only automatically realize the double automatic feeding of the steel cup bodies to meet the upper and lower pressing cup requirements of the front head tube of the frame body, but also realize the continuous feeding of the steel cup bodies under the action of gravity.

[0019] 3.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figures 1 to 7This invention provides a technical solution: a vehicle frame assembly line with detection function, including a fixed bracket 1 and a pressure cup oil injection assembly 6. An oil tank 5 is fixed to the top of the fixed bracket 1. The pressure cup oil injection assembly 6 is located at the front end of the fixed bracket 1. The pressure cup oil injection assembly 6 includes a cylinder 601, an inner pressure plate 602, a piston rod 603, a pressure spring 604, an outer pressure plate 605, a drive rod 606, a notch 607, a piston cylinder 608, a pressure head 609, and an oil injection hole 610. The cylinder 601 is bolted to the fixed bracket 1. An inner pressure plate 602 is fixedly connected to the top of the fixed bracket 1 and to the output end of the cylinder 601. A piston rod 603 is fixedly connected to the middle of the inner pressure plate 602, and pressure springs 604 are connected to both sides of the inner pressure plate 602. An outer pressure plate 605 is elastically connected to the end of the pressure spring 604 away from the inner pressure plate 602, and a drive rod 606 is fixedly connected to the rear end of the side of the outer pressure plate 605. Two staggered notches 607 are provided in the middle of the drive rod 606, and a piston cylinder 6 is connected to the middle of the bottom of the outer pressure plate 605. 08, and the inner cavity of the piston cylinder 608 is tightly fitted with the drive rod 606. The side of the piston cylinder 608 is connected to the oil tank 5 through an oil supply pipe. A pressure head 609 is fixedly installed at the bottom of the piston cylinder 608, and the pressure head 609 has an oil injection hole 610 that communicates with the inner cavity of the piston cylinder 608. A pressure oil outlet assembly 4 is fixed at the middle of the front end of the fixed bracket 1. The pressure oil outlet assembly 4 includes a base 401 and an oil chamber 402. The bottom ear plate of the base 401 is fixed to the fixed bracket 1 by bolts, and the base 401 The oil chamber 402 is provided inside, and the side of the oil chamber 402 is connected to the oil tank 5 through an oil supply pipe. The pressure oil outlet assembly 4 also includes a cone 403 and a spring rod 404. The top opening of the oil chamber 402 is provided with a cone 403, and the spring rod 404 is slidably installed inside the cone 403. The pressure oil outlet assembly 4 also includes a frustum 405 and a support plate 406. The bottom of the spring rod 404 is fixedly connected to the frustum 405 that cooperates with the cone 403, and the top of the spring rod 404 is fixedly connected to the support plate 406.

[0030] The specific operation is as follows: Under the push of cylinder 601, the outer pressure plate 605 drives the pressure head 609 at the bottom of piston cylinder 608 to first contact the top of the head tube of frame body 10. On the one hand, the steel cup body 705 at the top is pressed into the top opening of the head tube, and on the other hand, the steel cup body 705 at the bottom is pressed into the bottom opening of the head tube. During this process, the pressure at several points of cylinder 601 is transmitted through the front end of the head tube of frame body 10 to the support plate 406 above the base 401, so that the support plate 406 overcomes the elastic force of spring rod 404 to open the channel blocked by the cone 405 and the cone 403 at the top opening of oil chamber 402, so that the oil in oil chamber 402 is poured into the steel cup body 705 at the bottom through the open cone 403. After that, the inner pressure plate 602... Overcoming the elastic force of the pressure spring 604 drives the piston rod 603 to pressurize inside the piston cylinder 608, injecting the oil in the piston cylinder 608 into the steel cup body 705 at the top through the pre-reserved oil injection hole 610 on the pressure head 609. This completes the cup pressing and oil injection process of the front head tube of the frame body 10. Under the thrust provided by the cylinder 601, this application sequentially completes the three processes of double feeding of the steel cup body 705, double cup pressing of the front head tube of the frame body 10, and double oil injection of the upper and lower steel cup bodies 705. This allows the cup pressing, marking, and oil injection of the frame body 10 to be completed in one process, greatly improving production efficiency. At the same time, the power for feeding, cup pressing, and oil injection processes is provided by one cylinder 601, greatly reducing production costs.

[0031] Please see Figures 5 to 6 The fixed bracket 1 has a dual feeding assembly 7 at its rear end. The dual feeding assembly 7 includes a platform 701, a pusher block 702, and a drive groove 703. The base of the upper and lower platforms 701 is fixed to the fixed bracket 1, and the pusher block 702 is slidably installed at the rear end of the platform 701. The pusher block 702 has a drive groove 703 in the middle. The top conical surface of the drive groove 703 cooperates with the outer slope of the notch 607 to push out, and the bottom conical surface of the drive groove 703 cooperates with the inner slope of the notch 607 to retract. The dual feeding assembly 7 also includes a material cylinder 704, a steel bowl body 705, and a notch 706. The platform 701 has a material cylinder 704 embedded at the front end, and steel bowl bodies 705 are stacked inside the material cylinder 704. The steel bowl body 705 has two notches 706 in the middle and at the bottom, and the notches 706 correspond to the height of any one of the steel bowl bodies 705. The dual feeding assembly 7 also includes a gantry frame 707, a discharge sensor 708 and a limit sensor 709. The gantry frame 707 is fixed at the front and rear ends of the two notches 706 of the steel bowl body 705, and the discharge sensor 708 is set in the middle opening of the gantry frame 707. The limit sensor 709 is fixed at the front end of the gantry frame 707.

[0032] The specific operation is as follows: Steel cup bodies 705 are stacked vertically and inserted through the top opening of the material cylinder 704. The material cylinder 704 has notches 706 at both ends that match the height of any of the steel cup bodies 705. During use, the cylinder 601 drives the inner pressure plate 602 and outer pressure plate 605 to descend synchronously. Before the pressure head 609 contacts the front end tube of the frame body 10, the drive rod 606 fixed to the rear side of the outer pressure plate 605 engages with the push blocks 702 at the rear ends of the upper and lower platforms 701. The push blocks 702 are ejected by the engagement of the top conical surface of the drive groove 703 with the outer inclined surface of the recess 607, and the push blocks 702 are pushed out by the engagement of the bottom conical surface of the drive groove 703 with the inner inclined surface of the recess 607. The retraction enables the dual automatic supply of the upper and lower steel cup bodies 705 during the descent of the outer pressure plate 605. This application links the pressing process of the outer pressure plate 605 driven by the cylinder 601 with the dual feeding of the steel cup bodies 705. This not only automatically realizes the dual automatic feeding of the steel cup bodies 705 to meet the upper and lower pressing cup requirements of the front head tube of the frame body 10, but also realizes the continuous feeding of the steel cup bodies 705 under the action of gravity, and can continuously execute the pressing cup process. Furthermore, this application sets a discharge sensor 708 in the middle opening of the gantry 707 to detect whether a steel cup body 705 is pushed out each time it is fed and reminds the staff to replenish it in time to prevent the omission of steel cup bodies 705.

[0033] Please see Figures 1 to 2 The fixed bracket 1 has connecting arms 2 fixed on both sides of the front end, and a laser marking machine 3 is connected between the two connecting arms 2. The fixed bracket 1 has an assembly line 8 at the front end, and the assembly line 8 is driven by the meshing of the two side chains to the assembly bracket 9. The frame body 10 is placed on the top of the assembly bracket 9, and the upper and lower ends of the head tube at the front end of the frame body 10 correspond to the base 401 and the pressure head 609 respectively. The inner side of the main beam tube at the front end of the frame body 10 corresponds to the laser marking machine 3.

[0034] The specific operation is as follows: the frame body 10, which is placed upside down on the assembly bracket 9, is sequentially fed into the pressure cup, coding, and oiling integrated machine under the conveyor of the assembly line 8. The gantry 707 at the front end of the notches 706 at both ends of the material cylinder 704 is equipped with limit sensors 709 to detect whether the front end tube of the frame body 10 is in a preset position between the base 401 and the pressure head 609, so as to prevent the front end tube of the frame body 10 from shifting or tilting, which would lead to assembly errors later. At this time, the front main beam tube of the frame body 10 is also located inside the laser coding machine 3, and the laser coding machine 3 marks the frame number on the front main beam tube of the frame body 10.

[0035] In summary, when using this frame assembly line with detection function, the frame body 10, placed upside down on the assembly bracket 9, is sequentially fed into the pressure cup, marking, and oiling integrated machine under the conveyor of the assembly line 8. Limit sensors 709 are installed on the gantry 707 at the upper and lower ends of the material cylinder 704 and the front end of the notches 706 to detect whether the front end tube of the frame body 10 is in a preset position between the base 401 and the pressure head 609, preventing the front end tube of the frame body 10 from shifting or tilting, which could lead to assembly errors later. At this time, the front main beam tube of the frame body 10 is also located inside the laser marking machine 3, which marks the frame number on the front main beam tube of the frame body 10. The steel cup bodies 705 are then stacked vertically and passed through... The material is inserted through the top opening of the material cylinder 704. The material cylinder 704 has notches 706 at its upper and lower ends that are adapted to the height of any of the steel cup bodies 705. During use, the cylinder 601 drives the inner pressure plate 602 and the outer pressure plate 605 to descend synchronously. Before the pressure head 609 contacts the front end tube of the frame body 10, the drive rod 606 fixed to the rear end of the side of the outer pressure plate 605 cooperates with the push blocks 702 at the rear ends of the upper and lower platform 701. The push block 702 is ejected by the top conical surface of the drive groove 703 cooperating with the outer inclined surface of the recess 607, and retracted by the bottom conical surface of the drive groove 703 cooperating with the inner inclined surface of the recess 607. This allows the upper and lower steel cup bodies to descend during the descent of the outer pressure plate 605. The dual automatic feeding of the steel cup body 705 is achieved by linking the pressing process of the outer pressure plate 605 driven by the cylinder 601 with the dual feeding of the steel cup body 705. This not only automatically feeds the steel cup body 705 to meet the pressing needs of the front head tube of the frame body 10, but also enables continuous feeding of the steel cup body 705 under gravity, allowing for continuous execution of the pressing process. Furthermore, this application uses a discharge sensor 708 installed in the middle opening of the gantry 707 to detect whether a steel cup body 705 is pushed out during each feeding and reminds the operator to replenish it in time, preventing the omission of steel cup bodies 705. Under the push of the cylinder 601, the outer pressure plate 605 drives the pressing head 609 at the bottom of the piston cylinder 608 to... First, the cylinder 601 contacts the top of the head tube of the frame body 10. On one hand, the top steel cup body 705 is pressed into the top opening of the head tube; on the other hand, the bottom steel cup body 705 is pressed into the bottom opening of the head tube. During this process, the pressure at several points on the cylinder 601 is transmitted through the front end of the head tube of the frame body 10 to the support plate 406 above the base 401. This allows the support plate 406 to overcome the elasticity of the spring rod 404, opening the passage between the cone 405 and the cone opening 403 at the top of the oil chamber 402, which was previously blocked. This allows the oil in the oil chamber 402 to flow into the bottom steel cup body 705 through the open cone opening 403. Afterward, the inner pressure plate 602 overcomes the elasticity of the pressure spring 604, causing the piston rod 603 to pressurize within the piston cylinder 608.The oil in the piston cylinder 608 is injected into the steel cup body 705 at the top through the pre-drilled oil injection hole 610 on the pressure head 609. This completes the cup pressing and oil injection process of the front head tube of the frame body 10. Under the thrust provided by the cylinder 601, this application sequentially completes three processes: double feeding of the steel cup body 705, double cup pressing of the front head tube of the frame body 10, and double oil injection of the upper and lower steel cup bodies 705. This allows the cup pressing, marking, and oil injection of the frame body 10 to be completed in one process, greatly improving production efficiency. Furthermore, the power for feeding, cup pressing, and oil injection is all provided by a single cylinder 601, significantly reducing production costs.
