Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve seat processing, in particular to a drilling device for an electromagnetic valve seat. Background Art

[0002] The solenoid valve is a basic component used to control fluid automation. There is a closed cavity in the solenoid valve, with through holes at different positions. Each hole leads to a different oil pipe. The valve is in the middle of the cavity, and there are two electromagnets on both sides. The valve body will be attracted to the side where the magnet coil is energized. The movement of the valve body is controlled to block or leak different oil drain holes, and the oil inlet hole is normally open. The hydraulic oil will enter different oil drain pipes, and then the oil pressure will push the piston of the oil steel, and the piston will drive the piston rod, and the piston rod will drive the mechanical device. The solenoid valve is generally connected to the base by bolts, and then installed or fixed through the base.

[0003] The solenoid valve seat needs to be drilled during the processing. When drilling the existing solenoid valve seat, the solenoid valve seat that needs to be drilled is generally placed under the drilling machine manually, and then the solenoid valve seat is drilled by the drilling machine. After the drilling operation of the solenoid valve seat is completed, the solenoid valve seat that has completed the drilling operation is manually removed. This loading and unloading method is inefficient, and in order to avoid harming the loading and unloading staff, the drilling machine often needs to be stopped during loading and unloading, thereby extending the drilling time of the solenoid valve seat, thereby affecting the overall production efficiency of the solenoid valve seat.

[0004] Based on this, it is necessary to design a drilling device for the solenoid valve seat with automatic loading and unloading functions to improve the production efficiency of the solenoid valve seat. Utility Model Content

[0005] Technical solution: A drilling device for an electromagnetic valve seat, comprising a bracket, a frame, a conveyor belt assembly, a limit protrusion, a discharge pushing cylinder and a drilling mechanism. No less than four brackets for supporting the device are symmetrically installed on both sides of the frame. A conveyor belt assembly is rotatably arranged on the frame. Limit protrusions are evenly spaced on the conveyor belt of the conveyor belt assembly. The distance between two adjacent limit protrusions is adapted to the specifications of the electromagnetic valve seat. The conveyor belt assembly rotates the electromagnetic valve seat to the bottom of the drilling mechanism installed on the frame. The drilling mechanism performs drilling operation on the electromagnetic valve seat. The discharge pushing cylinder installed on the side wall of the frame pushes the electromagnetic valve seat that has completed the drilling operation away from the conveyor belt assembly.

[0006] In addition, it is particularly preferred that the drilling mechanism includes a lifting cylinder, a mounting cross plate and a drilling assembly, the lifting cylinders are installed on both symmetrical sides of the frame, the movable ends of the lifting cylinder piston rods are commonly connected to the mounting cross plate, and the bottom of the mounting cross plate is installed with a drilling assembly for drilling holes in the solenoid valve seat, when the lifting cylinder piston rod extends upward, the drilling assembly moves away from the solenoid valve seat, and when the lifting cylinder piston moves downward in a contracted manner, the drilling assembly approaches the solenoid valve seat and performs drilling operations on it.

[0007] In addition, it is particularly preferred that a limit assembly is also included for limiting and fixing the solenoid valve seat to facilitate the drilling operation of the drilling mechanism. The limit assembly is arranged below the mounting cross plate. The limit assembly includes a limit cylinder and a limit clamping plate. Limit cylinders are symmetrically arranged on both sides of the frame. The movable ends of the limit cylinder piston rods are both facing the conveyor belt assemblies and the ends thereof are connected to limit clamping plates for limiting and clamping the solenoid valve seat. When the piston rods of the two symmetrical limit cylinders extend, the two limit clamping plates clamp and fix the solenoid valve seat.

[0008] In addition, it is particularly preferred that the facing ends of the two limit clamping plates are both equipped with rubber pads for providing protection for the solenoid valve seat.

[0009] In addition, it is particularly preferred that limiting plates for preventing the solenoid valve seat from sliding off the conveyor belt assembly are also provided on both sides of the frame in the length direction.

[0010] In addition, it is particularly preferred that a receiving platform is vertically installed on one side of the frame, and the receiving platform is arranged in the opposite direction of the piston rod of the unloading push cylinder. When the piston rod of the unloading push cylinder extends, the solenoid valve seat that completes the drilling operation is pushed to the receiving platform to realize unloading.

[0011] Furthermore, it is particularly preferred that a scraper for scraping off drilling debris on the surface of the solenoid valve seat is installed on the receiving platform.

[0012] Compared with the prior art, the utility model has the following advantages: when loading, the loading personnel places the solenoid valve seat between the two limit protrusions on the conveyor belt assembly, and conveys the solenoid valve seat to the bottom of the drilling assembly through the conveyor belt assembly, clamps and limits the solenoid valve seat through the limit cylinder and the limit clamping plate, and the drilling assembly performs drilling operation on the solenoid valve seat, thereby achieving the effect of automatically conveying the solenoid valve seat to the bottom of the drilling assembly for drilling operation; the solenoid valve seat that has completed the drilling operation is pushed away from the conveyor belt assembly by the unloading push cylinder, thereby achieving the function of automatically unloading the solenoid valve seat that has completed the drilling operation.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] Embodiment: A drilling device for a solenoid valve seat, such as Figure 1 As shown, it includes a bracket 1, a frame 2, a conveyor belt assembly 3, a limiting convex block 31, a discharge pushing cylinder 8 and a drilling mechanism. Six brackets 1 for supporting the device are symmetrically installed on both sides of the frame 2. The bracket 1 is a "7"-shaped structure. A conveyor belt assembly 3 is rotatably arranged on the frame 2. The conveyor belt assembly 3 includes a transmission roller rotatably installed on the left and right ends of the frame 2, a transmission belt between the two transmission rollers and a driving motor for driving the transmission roller to move. The front and rear sides of the frame 2 are also provided with a transmission belt for preventing the electromagnetic valve seat from the conveyor belt assembly The limit plate 21 slides down on the conveyor belt of the conveyor belt assembly 3, and the limit protrusions 31 are evenly spaced. The distance between two adjacent limit protrusions 31 is adapted to the specifications of the solenoid valve seat, and the distance between the two limit protrusions 31 can be adapted to the length or width of the solenoid valve seat. The conveyor belt assembly 3 rotates and transports the solenoid valve seat to just below the drilling mechanism installed on the frame 2. The drilling mechanism drills the solenoid valve seat, and the unloading pushing cylinder 8 installed on the side wall of the frame 2 pushes the solenoid valve seat that has completed the drilling operation away from the conveyor belt assembly 3.

[0019] like Figure 1As shown, the drilling mechanism includes a lifting cylinder 4, a mounting cross plate 5 and a drilling assembly 51. The lifting cylinder 4 is installed on both sides of the frame 2 that are symmetrical in front and back. The movable ends of the piston rods of the lifting cylinders 4 are commonly connected to the mounting cross plate 5. A drilling assembly 51 for drilling holes in the solenoid valve seat is installed at the bottom of the mounting cross plate 5. The drilling assembly 51 includes a drilling motor and a drill bit that is easy to replace. When the piston rod of the lifting cylinder 4 extends upward, the drilling assembly 51 is away from the solenoid valve seat. When the piston of the lifting cylinder 4 contracts downward, the drilling assembly 51 approaches the solenoid valve seat and performs drilling operations on it.

[0020] like Figure 1 and Figure 2 As shown, it also includes a limit assembly for limiting and fixing the solenoid valve seat to facilitate the drilling operation of the drilling mechanism. The limit assembly is arranged below the mounting cross plate 5. The limit assembly includes a limit cylinder 6 and a limit clamping plate 61. The limit cylinders 6 are arranged on both sides of the front and rear symmetrical sides of the frame 2. The movable ends of the piston rods of the limit cylinders 6 are both facing the conveyor belt assembly 3 and the ends thereof are connected with limit clamping plates 61 for limiting and clamping the solenoid valve seat. The facing ends of the two limit clamping plates 61 are installed with rubber pads 7 for providing protection for the solenoid valve seat. When the piston rods of the two symmetrical limit cylinders 6 extend, the two limit clamping plates 61 approach the solenoid valve seat and gradually clamp and fix the solenoid valve seat, thereby facilitating the drilling operation of the drilling assembly 51.

[0021] like Figure 1 and Figure 3 As shown, a receiving platform 9 is vertically installed on the rear side of the frame 2, and the receiving platform 9 is arranged opposite to the unloading and pushing cylinder 8. When the piston rod of the unloading and pushing cylinder 8 extends, the solenoid valve seat that has completed the drilling operation is pushed to the receiving platform 9 to realize the unloading function of the solenoid valve seat. A scraper 10 for scraping off drilling debris on the surface of the solenoid valve seat is installed on the receiving platform 9. When the solenoid valve seat passes through the receiving platform 9, the scraper 10 scrapes off the debris on the top surface of the solenoid valve seat.

[0022] When in use, the solenoid valve seat is placed on the conveyor belt between the two limit protrusions 31, and the conveyor belt assembly 3 rotates and transports the solenoid valve seat to just below the drilling assembly 51. At this time, through the extension movement of the piston rod of the limit cylinder 6, the limit clamping plates 61 on both sides approach the solenoid valve seat and clamp it to fix it; then, the piston rod of the lifting cylinder 4 contracts and moves downward, and the drilling assembly 51 drills the solenoid valve seat just below it. After the drilling assembly 51 completes the drilling operation on the solenoid valve seat, the piston rod of the lifting cylinder 4 extends and moves upward, and the drilling assembly 51 moves away from the solenoid valve seat; the piston rod of the limit cylinder 6 moves in The solenoid valve seat is retracted and the limit clamping plates 61 on both sides gradually move away from the solenoid valve seat, thereby releasing the limit clamping effect on the solenoid valve seat. The conveyor belt assembly 3 transports the solenoid valve seat that has completed the drilling operation to the right. When the solenoid valve seat is transported to the rear of the unloading push cylinder 8, that is, when the piston rod of the unloading push cylinder 8 is directly opposite to the solenoid valve seat, the piston rod of the unloading push cylinder 8 extends, thereby pushing the solenoid valve seat to the receiving platform 9. When the solenoid valve seat passes through the receiving platform 9, the scraper 10 above the receiving platform 9 scrapes off the drilling debris on the surface of the solenoid valve seat, thereby achieving the effect of cleaning the surface of the solenoid valve seat.
