Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting machine technology, and in particular to a valve lifting machine. Background Technology
[0002] Valve lifters are used as feeding devices for lifting valves in various valve grinding machine line processes, such as engine full-length cutting, valve disc outer circle grinding, valve lock groove grinding, valve stem end face grinding, and valve cone surface grinding. During the processing, the lifter transports the valve to the next production process for the next processing operation.
[0003] Traditional valve lifters have a separate material rack from the lifter, requiring manual hanging, which is time-consuming and labor-intensive, reducing production efficiency. At the same time, the linear guide travel of the lifter is fixed, and traditional lifters cannot meet the requirements when a certain feeding height is needed. Therefore, we propose a valve lifter.

[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0025] like Figure 1-8 As shown, a valve lifter includes a base plate 1 and columns 2 located on both sides of the base plate 1. A linear module 3 is installed on one side of the column 2. The linear module 3 is fixedly installed on the column 2 by a connector 27, which is a connecting plate and screws.
[0026] The linear module 3 includes a linear guide rail 6 and a drive motor 8 located at one end of the linear guide rail 6. The drive motor 8 is a servo motor. A groove is provided on the linear guide rail 6, and a transmission wheel 5 is rotatably installed at both ends of the groove. The drive motor 8 is connected to the transmission wheel 5 at one end. A transmission belt 4 is sleeved on the transmission wheels 5 at both ends. The transmission belt 4 is located in the groove. A slider 7 is slidably connected to the linear guide rail 6. The slider 7 is fixedly connected to the transmission belt 4. A material rack 9 is installed on the slider 7. A slide rail 21 is installed on the other side column 2. The material rack 9 and the slide rail 21 are both inclined in the same direction.
[0027] The material rack 9 includes a connecting frame 10, a baffle 11, and two slide rods 14. The connecting frame 10 is installed obliquely on the slider 7. The connecting frame 10 has openings on both sides. The baffle 11 is rotatably connected to the opening on the bottom side of the connecting frame 10 via a rotating shaft 12. The two slide rods 14 are fixedly connected to the openings on both sides to form a track. A stop bar 13 is connected to the baffle 11, and the stop bar 13 is located at the bottom of the two slide rods 14.
[0028] A proximity switch 16 is mounted on the top of the linear guide rail 6. A connecting plate 17 is connected to the linear guide rail 6 on one side of the proximity switch 16. A cylinder 18 is mounted on the connecting plate 17. A connecting plate 29 is mounted on the output end of the cylinder 18. A pull rod 20 is mounted on the connecting plate 29. The direction of the pull rod 20 is perpendicular to the rotation direction of the baffle 11.
[0029] The slide 21 consists of two parallel slide plates 23. The slide 21 is mounted on a column 2 on one side via a fixing seat 22. Two cylinders 24 are installed at different heights at the same cross section position on both slide plates 23. The output ends of the two cylinders 24 are located between the two slide plates 23. A proximity switch 25 is installed on the slide plate 23 on one side of the cylinder 24.
[0030] A control box 26 is installed between the two columns 2. The control box 26 contains a PLC controller. The drive motor 8, cylinder 18, cylinder 24, proximity switch 16, and proximity switch 25 are all electrically connected to the PLC controller.
[0031] Working principle of this utility model:
[0032] According to actual production needs, a linear module 3 with a suitable stroke height is selected and installed on the column 2 via connector 27. The control box 26 controls the initial position of the slide rod 14 at the bottom of the material rack 9 to be connected to the track of slide 21. The valve 15 enters the slide 21 sequentially from the previous process through the external track. After the proximity switch 25 detects the valve 15, it transmits the signal to the control box 26. The proximity switch is a mature existing technology, and its electrical connection and control technology will not be described in detail here.
[0033] The control box 26 controls the output ends of the two cylinders 24 to retract, thereby opening the channel and allowing the valve 15 to slide into the material rack 9 through the slide rod 14. When the number of valves 15 on the material rack 9 reaches the preset value of the control box 26, the cylinder 24 keeps the slide rail 21 closed, and starts the drive motor 8 to drive the transmission wheel 5 to rotate. The transmission wheel 5 drives the transmission belt 4 to move, thereby driving the slider 7 to slide on the linear guide rail 6. When the slider 7 moves upward to the detection position of the proximity switch 16, the proximity switch 16 transmits a signal to the control box 26 to control the drive motor 8 to be turned off so that the slider 7 can be accurately positioned. At this time, the position of the pull rod 20 is close to the top of the baffle 11. The cylinder 18 is started to drive the connecting plate 29 and the pull rod 20 on it to move. After the pull rod 20 contacts the baffle 11, it drives the baffle 11 to rotate through the rotating shaft 12, so that the stop rod 13 moves to the bottom side of the slide rod 14, thereby opening the channel of the slide rod 14. The valve 15 slides into the next process for processing through the slide rod 14.
[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
