[0023] Example 1

[0024] See Figures 1 to 4 In an embodiment of the present utility model, a vertical CNC deep hole drilling machine includes a drilling machine base 1, a support plate 2 is vertically fixedly installed on the drilling machine base 1, a connecting plate 3 is horizontally fixedly installed on the upper end of the support plate 2, a guide plate 5 is fixedly installed on the connecting plate 3 away from the support plate 2, guide shafts 15 are symmetrically fixedly installed on the guide plate 5, guide blocks 6 are slidably installed between the guide shafts 15, a deep drilling mechanism is installed on the guide blocks 6 for performing deep drilling operations on the workpiece, a motor frame 20 is fixedly installed on the connecting plate 3, a drive shaft 11 is rotatably installed on the motor frame 20, and a power mechanism for driving the guide block 6 to move on the guide shaft 15 is provided on the drive shaft 11.

[0025] In one aspect of this embodiment, the deep drilling mechanism includes a motor frame 9 mounted on a guide block 6. A deep drilling motor 10 is mounted on the motor frame 9. The output end of the deep drilling motor 10 is connected to a deep drilling rod 7. A deep drilling bit 8 is fixedly mounted on the deep drilling rod 7. When the deep drilling motor 10 is activated, the deep drilling rod 7 is driven to rotate, which ultimately drives the deep drilling bit 8 to effectively rotate, thereby performing a deep drilling operation on the workpiece.

[0026] In addition, in order to ensure the power source of the power mechanism, in this embodiment, a power motor 4 is also installed on the motor frame 20 , and the output end of the power motor 4 is connected to the drive shaft 11 .

[0027] In one case of this embodiment, the power mechanism includes a connecting rod a16 hingedly mounted on the drive shaft 11, a connecting rod b17 hingedly mounted on the connecting rod a16, a transmission shaft 18 rotatably mounted on the connecting rod b17, a stretching rod 12 rotatably mounted on the transmission shaft 18, and the stretching rod 12 is hingedly mounted on the guide block 6. The power mechanism also includes a depth adjustment component.

[0028] The depth adjustment assembly includes an adjustment shaft 19 rotatably mounted in a radial position of the transmission shaft 18 , the outer wall of the adjustment shaft 19 is mounted on the drive shaft 11 through a threaded area 13 , and a handle 14 is also installed at one end of the adjustment shaft 19 away from the transmission shaft 18 .

[0029] The working principle of the above-mentioned power mechanism is: start the power motor 4 to rotate the drive shaft 11, and then under the action of the adjusting shaft 19, the transmission shaft 18 moves synchronously, and then under the action of the stretching rod 12, the guide block 6 moves up and down along the guide shaft 15, and finally drives the deep drilling mechanism to perform drilling operations.

[0030] Example 2

[0031] The present invention also provides another embodiment, which differs from the above embodiment in that a groove structure is provided on both the connecting plate 3 and the guide plate 5. The provision of the groove structure prevents the entire power mechanism from interfering with the connecting plate 3 and the guide plate 5 during operation.

[0032] In summary, during operation, the workpiece to be drilled is placed on the drilling machine base 1. Then, according to the required drilling depth, the handle 14 is rotated to change the position between the drive shaft 11 and the transmission shaft 18. Finally, with the cooperation of the power mechanism, the deep drilling mechanism is activated to drill the workpiece. The entire operation process is quick and convenient, and is worthy of widespread use.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
