Description

Technical Field

[0001] The present invention relates to the technical field of engine connecting rod weighing, and specifically to an engine connecting rod weighing and pushing device. Background Art

[0002] The connecting rod is an important component of an automotive engine. Due to its structural characteristics, the center of gravity is not at the I-shaped rib where it is easy to grip, so it is not easy to quickly, continuously and stably grip the connecting rod.

[0003] During the process of connecting rod mass detection, it is necessary to detect the weights of a large number of connecting rods. In the prior art, most use conveyor belts for conveying, and achieve the purpose of automatic weighing through the conveying of the conveyor belt, so as to adapt to the rapid detection of a large number of connecting rods. However, due to the offset of the center of gravity of the connecting rod, it is not easy for the connecting rod to directly slide from the conveyor belt onto the weight detection platform, often resulting in the connecting rod getting stuck between the weighing device and the conveyor belt, causing material jams, and thus unable to achieve large-batch continuous weighing, seriously affecting the conveying and weighing efficiency.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] An engine connecting rod weighing and pushing device includes a chassis 1 and a connecting rod 8. A conveyor belt 3 driven by a motor is provided at the upper end of the chassis 1. A drive frame 2 is provided at the upper end of the chassis 1. The conveyor belt 3 is installed on the drive frame 2. The lower end of the weighing device 10 is fixedly installed on the chassis 1. The tray 11 at the upper end of the weighing device 10 is connected to the upper end of the conveyor belt 3. The connecting rod 8 is placed on the conveyor belt 3 and is horizontally transported by the conveyor belt 3.

[0031] At the upper end of the chassis 1, there is an upper guide rail 4 parallel to the conveyor belt 3. At one end of the conveyor belt 3 close to the upper guide rail 4, there is a tray 11 connected to the weighing device 10 at the same height. On the upper guide rail 4, there is a slider 15 driven to slide horizontally by a telescopic rod 5. On the upper guide rail 4, there is a chute 16 penetrating up and down. The telescopic rod 5 is installed in parallel at the lower end of the upper guide rail 4. The end of the telescopic rod 5 is fixed on the side plate of the chassis 1, and the other end of the telescopic rod 5 is fixed on the bracket 6. The slider 15 is slidably installed in the chute 16. The telescopic rod 5 is used to drive the slider 15 and the bracket 6 to slide horizontally for adjustment. The height of the slider 15 is limited by the chute 16 on the upper guide rail 4, and the horizontal sliding installation of the slider 15 is realized.

[0032] At the lower end of the slider 15, there is a bracket 6. The lower end of the slider 15 is fixedly connected to the bracket 6. On the bracket 6, there is a rotating tube 7 rotatably installed vertically. At the upper end of the rotating tube 7, there is a driven gear 19 sleeved. The driven gear 19 is meshed and connected with a driving gear 18 driven by a driving motor 31 installed on the bracket 6. The driving motor 31 is used to drive the driving gear 18 to rotate. Through the meshing of the driving gear 18 and the driven gear 19, the rotating installation of the rotating tube 7 is realized.

[0033] At the lower end of the rotating tube 7, there is an arc-shaped push plate 9 that slides and fits the outer wall of the upper end of the conveyor belt 3. There is a sensor on the arc-shaped push plate 9. The driving motor 31, the sensor and the telescopic rod 5 are all electrically connected. When the connecting rod 8 is conveyed close to the arc-shaped push plate 9, the sensor sends a signal. The driving motor 31 drives the rotating tube 7 to rotate, so that the arc-shaped push plate 9 deviates from the running direction of the connecting rod 8, so that the connecting rod 8 can smoothly pass through the lower end of the rotating tube 7, avoiding blockage, and adapting to the continuous weighing of a large number of connecting rods 8.

[0034] When the connecting rod 8 is conveyed close to the arc-shaped push plate 9, the sensor sends a signal. The driving motor 31 drives the rotating tube 7 to rotate, so that the arc-shaped push plate 9 deviates from the running direction of the connecting rod 8, so that the connecting rod 8 can smoothly pass through the lower end of the rotating tube 7, avoiding blockage, and adapting to the continuous weighing of a large number of connecting rods 8.

[0035] After the connecting rod 8 passes through, through the rotation of the rotating tube 7, the arc-shaped push plate 9 is rotated to a horizontal position flush with the connecting rod 8. The arc-shaped push plate 9 is driven by the contraction of the telescopic cylinder 5 to push the connecting rod 8, so that the connecting rod 8 can smoothly enter the weighing device, avoiding material jamming.

[0036] Embodiment 2:

[0037] On the basis of Embodiment 1, in this embodiment, a pair of upper and lower symmetric limiting rings 22 are sleeved on the outer wall of the upper end of the rotating tube 7. The upper and lower distributed limiting rings 22 are respectively pressed on the upper and lower outer walls of the bracket 6. The rotating tube 7 penetrates the bracket 6 and is rotatably installed on the bracket 6 through a bearing 21.

[0038] For the connecting rod assemblies with different heights, the height of the arc-shaped push plate 9 will cause obstruction to the passing position of the connecting rod.

[0039] The height of the rotating tube 7 on the bracket 6 is limited by the limiting ring 22, so that the arc-shaped push plate 9 at the lower end of the rotating tube 7 is located at the upper end of the conveyor belt 3, and the lower end port of the rotating tube 7 is located at the upper end of the connecting rod 8, enabling the connecting rod 8 to smoothly penetrate through the lower end of the rotating tube 7, and then the arc-shaped push plate 9 is used to realize material pushing.

[0040] Embodiment 3:

[0041] On the basis of Embodiment 1, in this embodiment, a vertically penetrating lifting inner cavity 20 is provided in the inner cavity of the rotating tube 7. The middle section of the lifting inner cavity 20 is provided with a lifting groove 29 whose inner diameter is smaller than that of the lifting inner cavity 20. A lifting column 27 is vertically and slidably installed in the lifting groove 29. The upper end of the lifting column 27 is connected to the upper pulling rope 12. Limiting plates 28 are respectively arranged at the upper and lower ends of the lifting column 27. One end of the upper pulling rope 12 is fixed to the limiting plate 28 at the upper end of the lifting column 27. A guiding wheel 17 is arranged on the slider 15, and an ear seat 13 is arranged on the side plate of the chassis 1. The upper pulling rope 12 extends to the ear seat 13 along the guiding wheel 17, and the upper pulling rope 12 slidably penetrates through the ear seat 13. A baffle 14 is arranged at the lower end of the upper pulling rope 12. A lower pulling rope 30 is fixedly connected to the lower limiting plate 28 at the lower end of the lifting column 27. A vertical groove 23 is vertically penetrated through the outer arc wall at the lower end of the rotating tube 7. A lifting cross beam 24 is slidably penetrated and inserted in the vertical groove 23. The outer wall of the middle section of the lifting cross beam 24 is fixedly connected to the lower end of the lower pulling rope 30. Hinge seats 32 are arranged on the front and rear outer walls at the lower end of the arc-shaped push plate 9. A protective side plate 26 is rotatably installed on the hinge seats 32. The other end of the protective side plate 26 is fixedly connected to a traction rope 25. The other end of the traction rope 25 is fixedly connected to the front and rear ends of the lifting cross beam 24 extending outside the rotating tube 7.

[0042] For the connecting rod assemblies with irregular structures and serious center of gravity offset, they are prone to offset during the conveying process, especially at the interface position between the conveyor belt and the weighing device. After the center of gravity of the connecting rod is offset, under the push of the arc-shaped push plate 9, it is extremely easy to offset outward and cannot be accurately pushed to the weighing position.

[0043] The up and down sliding height of the lifting column 27 is limited by the limiting plate 28, and the lateral extension length of the upper pulling rope 12 is limited by the baffle 14. Thus, when the telescopic rod 5 drives the slider 15 to slide laterally, the baffle 14 is driven to rise. When the baffle 14 contacts the ear seat 13, with continuous sliding, the upper pulling rope 12 overcomes the gravity of the lifting column 27 and drives the lifting column 27 to rise. During the rising process of the lifting column 27, the lifting cross beam 24 is driven to rise through the lower pulling rope 30, and then the protective side plate 26 is driven to tilt and rotate through the traction rope 25, realizing the storage of the protective side plate 26.

[0044] When the telescopic rod 5 retracts and pushes the connecting rod 8, under the gravity of the lifting column 27, the upper pulling rope 12 relaxes, the baffle 14 descends, driving the protective side plate 26 to fit the outer wall of the upper end of the conveyor belt 3. Through the front and rear limitations of the protective side plate 26, the connecting rod 8 maintains a limited sliding at the connection position with the tray 11, ensuring accurate transportation to the weighing position.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
