Description

Technical Field

[0001] The invention relates to the field of vertical drilling machines, and more particularly to a vertical drilling machine for metal processing. Background Art

[0002] In modern manufacturing, metal processing is an extremely critical basic link and is widely used in many fields such as automobile manufacturing, aerospace, and mechanical equipment. Drilling, as one of the common processes in metal processing, plays an indispensable role in the manufacture of various parts. Its processing accuracy and efficiency directly affect the quality and production cycle of the final product. As an important equipment for metal drilling processing, vertical drilling machines have always occupied an important position in long-term industrial production.

[0003] In order to enable the vertical drilling machine to drill a hole at a certain angle on the workpiece to be processed, it is generally necessary to fix the workpiece to be processed on the workpiece table at a certain angle so that a certain angle is formed between the workpiece to be processed and the drill bit, so that the drill bit can drill an inclined hole at a certain angle on the workpiece to be processed, or an angle adjustment mechanism is generally provided at the installation position of the drive box of the vertical drilling machine. By adjusting the angle adjustment mechanism, the drive box is deflected at a certain angle, thereby causing the angle of the drill bit to change, so as to achieve drilling a hole at a certain angle on the workpiece to be processed. However, most of the angle adjustment mechanisms at the installation position of the existing drive box need to be locked and adjusted in the form of bolts, which is inconvenient. Therefore, in view of this, it is particularly necessary to design an angle adjustment mechanism that is convenient for the angle swing of the drive box, and has a strong linkage of the locking mechanism and is convenient to lock. For this reason, we propose a vertical drilling machine for metal processing to solve the above-mentioned problems. Summary of the invention

[0028] A limiting mechanism 12 is provided at the center position of the bottom of the middle seat plate 3. The limiting mechanism 12 includes a fixed plate 13 fixedly installed at the center position of the bottom of the middle seat plate 3. A telescopic plate 14 is provided on the bottom surface of the fixed plate 13 corresponding to the position of the top column 9, and positioning strips 15 are slidably connected on both sides of the telescopic plate 14. The bottom of the positioning strip 15 is fixedly welded on the fixed plate 13. A rotating disk 16 is provided at the bottom of the fixed plate 13. The top surface of the rotating disk 16 is in contact with the upper surfaces of several telescopic plates 14.

[0029] The operating principle of the angle fine-adjustment mechanism of this type of vertical drilling machine for metal processing is:

[0030] When it is necessary to adjust the drilling angle of the drill bit 21 so that the drill bit 21 can drill an oblique hole for the workpiece to be processed, first, the unlocking handle 1601 on the limiting mechanism 12 is toggled to drive the turntable 16 to rotate, and then through the limiting effect of the arc-shaped stroke groove 1602 and the positioning pile 1401, the plurality of telescopic plates 14 can be driven to retract inward at the same time, forcing the engaging cutting edges 1402 of the plurality of telescopic plates 14 to simultaneously disengage from the toothed edges on the corresponding rack 11, and at this time, the limiting effect on the plurality of top columns 9 can be unlocked, and then the drive box 18 can be toggled to perform Deflection, thereby controlling the angle of the drill bit 21 to deflect, so as to facilitate the subsequent drilling of inclined holes in the workpiece to be processed. When the adjusted angle meets the use requirements, the unlocking handle 1601 on the limiting mechanism 12 can be toggled in the reverse direction to drive the turntable 16 to rotate in the reverse direction. Through the limiting effect of the arc-shaped stroke groove 1602 and the positioning pile 1401, several telescopic plates 14 can be driven to extend outward at the same time, forcing the engaging cutting edges 1402 of several telescopic plates 14 to engage with the tooth edges on the corresponding rack 11 at the same time, and the limiting effect on several top columns 9 can be achieved.

[0031] Embodiment 2: In view of the above embodiment 1, further description is given, referring to Figure 1A driving motor 19 is fixedly installed on one side of the driving box 18, and a drilling telescopic rod 20 is arranged at the bottom of one side of the driving box 18, and a drill bit 21 is fixedly installed at the bottom of the drilling telescopic rod 20, and a feeding handle 22 is arranged on one side of the outer wall of the driving box 18, and a mounting seat 1801 is fixedly installed on the bottom of the driving box 18 near the driving motor 19 side, and a mounting seat 24 is fixedly installed on one side of the top of the base 26 through a column 23, and the bottom of the mounting seat 1801 and the top of the mounting seat 24 are fixedly installed on the top of the seat plate 24 and the bottom of the seat plate 12 respectively through bolts, and a workpiece support plate 25 is also fixedly installed on the column 23 through a sleeve.

[0032] The drive motor 19 can provide driving force for the rotation of the drill bit 21, and the feed handle 22 can control the extension and retraction of the drilling telescopic rod 20, thereby controlling the extension and retraction of the drill bit 21 (the specific structure and principle of the drive motor providing driving force for the rotation of the drill bit, and the specific structure and principle of the feed handle controlling the extension and retraction of the drilling telescopic rod are already existing known public technologies, so they will not be described in detail here), and the workpiece support plate 25 is convenient for placing the workpiece to be processed for drilling operations.

[0033] Embodiment 3: In view of the above-mentioned embodiments 1 and 2, further description is given, referring to Figure 5 and Figure 7 The sliding hole 301 at the position corresponding to the rack 11 and the seat cover 8 are both provided with an avoidance opening 801, the outer wall diameters of the fixed plate 13 and the rotating plate 16 are equal, the length of the telescopic plate 14 is smaller than the radius of the fixed plate 13, and the thickness of the telescopic plate 14 is equal to the thickness of the positioning strip 15.

[0034] The opening of the avoidance opening 801 can provide avoidance space for the installation and movement of the rack 11 to avoid interference. The length of the telescopic plate 14 is smaller than the radius of the fixed plate 13 to avoid the telescopic plate 14 being unable to be completely retracted between the fixed plate 13 and the turntable 16. The positioning strip 15 plays a positioning role in the reciprocating movement of the telescopic plate 14. The seat cover 8 can improve the stability of the installation and movement structure of the top column 9.
