Description

Technical Field

[0001] This utility model relates to the field of model processing technology, specifically a drilling device for model processing. Background Technology

[0002] With the progress of the times, models can be seen everywhere in people's daily lives. In the process of model production and processing, drilling devices are required. However, the existing model drilling devices have a relatively conventional drill bit connection method, which is not easy to manually and quickly replace the drill bit, increasing the workload of workers and is not conducive to processing holes of other sizes.

[0003] A search revealed an adjustable-angle drilling device for human body model production, application number CN202222416849.X. This device includes a base and a support. The support contains a pair of vertical plates, the tops of which are fixedly connected to the upper end of the support. A flip plate is held between the vertical plates. Both ends of the flip plate are rotatably connected to the vertical plates via a pair of rotating shafts. The end of the rotating shaft facing away from the flip plate extends through the vertical plates and is fitted with a first gear. A horizontal shaft is located above the flip plate, with both ends extending through the vertical plates and being fitted with second gears. The first and second gears on the same side are meshed. A drive device for rotating the horizontal shaft is fixed at the upper end of the support. A cylinder is fixed to the upper surface of the flip plate. A lifting frame connected to the cylinder is located below the flip plate, and a drill bit is located inside the lifting frame. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A drilling device for model processing includes a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the top of the fixed frame 2, a drilling motor 4 disposed below the top plate 3, the drilling motor 4 being capable of lifting and lowering, a hydraulic cylinder 9 fixedly mounted on the top of the top plate 3, a drive plate 10 fixedly connected to the output shaft at the bottom of the hydraulic cylinder 9, the drilling motor 4 fixedly mounted on the bottom of the drive plate 10, a drive shaft 5 fixedly connected to the output shaft at the bottom of the drilling motor 4, a mounting cylinder 6 movably inserted into the bottom end of the drive shaft 5, a drilling drill bit 7 fixedly connected to the bottom of the mounting cylinder 6, a clamping plate 8 disposed below the drilling motor 4, the clamping plate 8 movably clamping into an annular groove on the side of the mounting cylinder 6, the thickness of the clamping plate 8 being adapted to the width of the annular groove on the side of the mounting cylinder 6, and the base 1. A workbench 24 is fixedly connected to the top of the model. The top of the workbench 24 has an opening for use with the drilling bit 7. An electric push rod 27 is fixedly installed on the inner wall of the workbench 24. A drive plate 28 is fixedly connected to the output shaft of the electric push rod 27. A clamping plate 25 is connected to the upper part of the side of the drive plate 28 through a connecting rod 29. A soft pad 26 is fixedly connected to the side of the clamping plate 25. The soft pad 26 is made of rubber. The initial minimum distance between the two clamping plates 5 is smaller than the size of the model. The connecting rod 29 of appropriate length can be set according to actual needs.

[0022] Please see Figure 1-4A plug 11 is fixedly connected to the top of the mounting cylinder 6. A slot 12 adapted to the plug 11 is opened at the bottom of the drive shaft 5. The plug 11 is movably inserted into the slot 12. A stabilizing sleeve 13 is movably fitted on the surface of the drive shaft 5. A bracket 14 is fixedly connected to the side of the stabilizing sleeve 13. The end of the bracket 14 away from the stabilizing sleeve 13 is fixedly installed at the bottom of the drive plate 10. A stabilizing column 30 is fixedly connected to the inner wall of the fixing frame 2. A stabilizing block 31 is slidably connected to the surface of the stabilizing column 30. The front side of the stabilizing block 31 is fixedly connected to the rear side of the drive plate 10. The stabilizing column 30 and the stabilizing block 31 limit the movement trajectory of the drive plate 10, so that the drive plate 10 can only perform linear lifting and lowering movements. This protects the hydraulic cylinder 9 and prevents the output shaft of the hydraulic cylinder 9 from being subjected to forces other than those in the vertical direction.

[0023] Please see Figure 1-4 A fixed plate 15 is fixedly connected to the bottom of the stabilizing sleeve 13. A moving plate 16 is provided on the side of the fixed plate 15. A clamping plate 8 is fixedly connected to the moving plate 16. The distance between the fixed plate 15 and the moving plate 16 can be varied. A telescopic rod 17 is fixedly connected to the side of the fixed plate 15. The end of the telescopic rod 17 away from the fixed plate 15 is fixedly connected to the moving plate 16. A spring 18 is sleeved on the surface of the telescopic rod 17. One end of the spring 18 is fixedly connected to the fixed plate 15, and the other end of the spring 18 is fixedly connected to the moving plate 16. The spring 18 is in a compressed state as shown in the figure. In this way, the spring 18 has the tendency to drive the moving plate 16 to move closer to the mounting cylinder 6. A limit groove 19 is opened on the side of the stabilizing sleeve 13. A track 20 is fixedly connected to the inner wall of the limit groove 19. A limit plate 21 is slidably connected to the surface of the track 20. A locking rod 22 is fixedly connected to the bottom of the limit plate 21. A side plate 23 is fixedly connected to the side of the moving plate 16. The bottom end of the locking rod 22 passes through the side plate 23.

[0024] In use, the entire drilling device is used in conjunction with an external electrical control box. The workflow of automated equipment is generally done in conjunction with this control box, which includes a standard controller, such as the Siemens S7-1200. The model is placed on top of the worktable 24. The control box controls two electric push rods 27, which drive the clamping plates 25 via the drive plate 28 and connecting rod 29. The two clamping plates 25 then hold the model in place. The drilling motor 4 then drives the drilling bit 7 to rotate via the drive shaft 5, insert block 11, and mounting cylinder 6. The hydraulic cylinder... 9. The working mechanism will cause the drive plate 10 to move downwards, and the drilling bit 7 will drill holes in the model. When it is necessary to remove the drilling bit 7, pull the limit plate 21 upwards. The limit plate 21 will cause the locking rod 22 to disengage from the side plate 23. Then, pull the side plate 23 to move away from the mounting cylinder 6. The side plate 23 will cause the clamping plate 8 to disengage from the annular groove on the side of the mounting cylinder 6 through the moving plate 16. The telescopic rod 17 and the spring 18 will be compressed. After the clamping plate 8 disengages from the annular groove on the side of the mounting cylinder 6, the drilling bit 7 will fall due to gravity, thus completing the removal of the drilling bit 7.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
