Description

Technical Field

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

[0002] Chinese patent number "CN218696595U" discloses a solenoid valve seat processing device, including a processing frame, a fixed seat is installed at the top of the processing frame, and a connecting plate is installed at the bottom of the fixed seat, a connecting rod is evenly installed at the bottom of the connecting plate, and a connecting ring is installed at the bottom of the connecting rod, and a cleaning ring is installed at the bottom of the connecting ring. After the current drilling process is completed, the electric push rod is started to drive the drilling head to rise, and the fourth motor is started to drive the driving gear to rotate. Under the meshing action, the driving gear drives the cleaning ring connected to the external gear to rotate, so that the drilling head can contact the cleaning brush inside the cleaning groove during the lifting process. That is, the cleaning function of the outside of the drilling head is realized through the action of the cleaning brush, thereby avoiding the effect of the drilling head being drilled again due to the attachment of waste chips.

[0003] The device can be used for drilling holes in solenoid valve seats. The cleaning brush can be used to clean the outside of the drilling head to avoid the effect of the drilling head being affected by the adhesion of waste chips. However, the device does not have a protective structure, which can easily cause the waste chips generated by drilling to fly around, making it inconvenient to clean. At the same time, the cleaning ring is not convenient to disassemble and replace, so improvements are proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that there is no protective structure, which easily causes waste chips generated by drilling to fly around, is inconvenient to clean, and the cleaning ring is not convenient to disassemble and replace, and proposes a solenoid valve seat processing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A clamping groove is provided at the bottom of the fixing frame. A cleaning ring is movably clamped inside the clamping groove.

[0010] Preferably, a driving structure for driving the moving block to move left and right is fixedly installed inside the mounting plate.

[0011] Preferably, the upper end surface of the processing machine frame is fixedly connected by means of bolts to a top plate. The mounting frame is clamped and fixed through the cooperation of the top plate. A driving structure for driving the mounting frame to move back and forth is fixedly installed inside the processing machine frame.

[0012] Preferably, a driving structure for driving the driving block to move left and right is fixedly installed inside the mounting frame.

[0013] Preferably, an installation bin is provided at the bottom of the processing machine frame. A clamping device is fixedly installed inside the installation bin. The top end of the clamping device is fixedly connected by means of bolts to a clamping frame.

[0014] For a solenoid valve seat processing device proposed by the present utility model, the beneficial effects are as follows: A complete protective plate is formed by two groups of semi-circular plates, and then it is fixed by a fixed annular sleeve to prevent separation. At the same time, the installation and disassembly of the protective plate are facilitated. When the drilling device processes the workpiece, the lower end surface of the protective plate will abut against the workpiece. At this time, the protective plate will move upward, thereby compressing the elastic member. And the drilling device is located inside the protective plate. At this time, the waste chips generated by drilling will not be thrown flying, which is convenient for subsequent cleaning. When the drilling is completed, the compressed elastic member will reset the protective plate. By the cooperation of the abutting block and the limiting block to fix the elastic member, the elastic member can be prevented from shifting and detaching from the protective plate. At the same time, it is convenient for the waste chips to fall, preventing the waste chips from accumulating inside the protective plate.

[0015] The L-shaped fixing frame can be moved through the driving structure. When the drilling device moves upward and is retracted after the drilling is completed, the clamping groove of the fixing frame moves to the lower part of the drilling device. At this time, the cleaning ring inside the clamping groove can clean the waste chips remaining at the position of the drill bit of the drilling device, avoiding the influence on the re-drilling effect of the drill bit due to the attachment of the waste chips.

An elastic member 13 is sleeved inside the protection plate 12. Both ends of the elastic member 13 abut against the abutting block 1202 and the moving plate 10. When the drilling device 11 processes the workpiece, the lower end surface of the protection plate 12 will abut against the workpiece. At this time, the protection plate 12 will move upward, thereby compressing the elastic member 13. And the drilling device 11 is located inside the protection plate 12. At this time, the waste chips generated by drilling will not be thrown flying, which is convenient for subsequent cleaning. When the drilling is completed, the compressed elastic member 13 will reset the protection plate 12.

[0026] The protection plate 12 is composed of two symmetric semi-circular plates that are snap-fitted together. A plurality of ring sleeve grooves 1201 are formed on the outer peripheral end surface of the protection plate 12. A fixed ring sleeve 14 is movably sleeved inside the ring sleeve grooves 1201. A limiting block 1203 for restricting the elastic member 13 is fixedly connected to the inner end surface of the abutting block 1202. The complete protection plate 12 is formed by two semi-circular plates, and then it is fixed by the fixed ring sleeve 14 to prevent separation, which facilitates the installation and disassembly of the protection plate 12. By the cooperation of the abutting block 1202 and the limiting block 1203 to fix the elastic member 13, the elastic member 13 can be prevented from shifting and detaching from the protection plate 12. At the same time, it is convenient for the waste chips to fall, preventing the waste chips from accumulating inside the protection plate 12.

[0027] A moving block 6 is slidably connected inside the mounting plate 5. An L-shaped fixing frame 8 is fixedly connected to the lower end surface of the moving block 6. A clamping groove 801 is formed at the bottom of the fixing frame 8. A cleaning ring is movably clamped inside the clamping groove 801. By fixing the cleaning ring through the clamping groove 801 inside the L-shaped fixing frame 8, the installation and disassembly of the cleaning ring are facilitated. At the same time, different cleaning rings can be replaced according to different drill bit sizes.

[0028] A driving structure 7 for driving the moving block 6 to move left and right is fixedly installed inside the mounting plate 5. By the movement of the moving block 6, the cleaning ring can be prevented from affecting the drilling.

[0032] Working mode; During work, the workpiece is fixed through the cooperation of the clamping device 2 and the clamping frame 201. The drilling device 11 is driven to move by the electric push rod 9. At this time, the drilling device 11 processes the workpiece, and the lower end surface of the protection plate 12 will abut against the workpiece. At this time, the protection plate 12 will move upward, thereby compressing the elastic member 13. The drilling device 11 is located inside the protection plate 12, so that the waste chips generated by drilling will not be thrown away, which is convenient for subsequent cleaning. When the drilling is completed, the compressed elastic member 13 will reset the protection plate. Then, the L-shaped fixing frame 8 can be moved through the driving structure 7. When the drilling is completed and the drilling device 11 moves upward and is retracted, the clamping groove 801 of the fixing frame 8 moves below the drilling device 11. At this time, the cleaning ring inside the clamping groove 801 can clean the waste chips remaining at the position of the drill bit of the drilling device 11, avoiding the influence of waste chip adhesion on the re-drilling effect of the drill bit. This device has good safety and is convenient for cleaning.
