Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a roughing and finishing drilling tool changing device. Background Technology

[0002] A drilling machine is a machine tool used to machine round holes in workpieces. It is a fundamental piece of equipment in machining and is widely used in metal processing, woodworking, PCB drilling, and other fields. Drilling machines primarily achieve drilling by rotating a cutting tool (drill bit) and applying axial feed force. Proper selection of the drilling machine type, cutting tools, and machining parameters can improve machining efficiency and accuracy. For high-precision requirements, it can be combined with a CNC drilling machine or subsequent finishing processes (such as reaming and boring) to ensure quality.

[0003] In drilling machine processing, roughing and finishing are two different process stages. Parameters, tools, and processes need to be selected reasonably according to the processing requirements. By rationally planning the roughing and finishing processes, both efficiency and accuracy can be taken into account, making it suitable for mass production or processing of high-requirement parts.

[0004] However, the tool changing speed of existing drilling machines is slow, which affects the processing efficiency. In order to solve the problem of slow tool changing speed in the prior art, this application sets up components such as insert blocks and support rods, so that the support rods can drive the corresponding insert blocks to slide horizontally, so that each insert block corresponds to a slot, achieving the effect of fixing the tool inside the support shaft. Therefore, a new solution is needed to solve this problem. Utility Model Content

The second drive rod is rotatably connected to the bracket.

The pressure block 10, via the support rod 9, drives two insertion blocks 8 to slide horizontally, ensuring each insertion block 8 corresponds to a slot 7, thereby fixing the tool body 5 inside the support shaft 4.

[0026] The support shaft 4 has four limiting rods 11 fixedly connected inside. Each pair of limiting rods 11 corresponds to a plug 8. Each limiting rod 11 is slidably connected to the corresponding plug 8 inside. The limiting rods 11 limit the sliding of the plug 8.

[0027] A first motor is fixedly installed on the lower surface of the support arm 2. A gear 12 is fixedly connected to the output end of the first motor. A gear ring 13 is fixedly connected to the top of the support shaft 4. The gear 12 is rotatably connected to the inside of the support cylinder 3. The gear 12 meshes with the gear ring 13. The gear 12 drives the support shaft 4 to rotate through the gear ring 13.

[0028] A second motor is fixedly installed on the top of the column 1. The output end of the second motor is fixedly connected to a first drive rod 14. The first drive rod 14 is rotatably connected to the column 1. The outer surface of the first drive rod 14 is threadedly connected to the inside of the support arm 2. The first drive rod 14 is used to drive the support arm 2 and other components to achieve lifting and lowering.

[0030] The upper surface of the base 16 is fixedly connected to the bottom shell 18. A stepper motor is fixedly installed inside the bottom shell 18. The output end of the stepper motor is fixedly connected to the cutter head 19. The outer surface of the cutter head 19 has slots 20 arranged at equal intervals. The slots 20 correspond to the tenons 6. The cutter head 19 clamps the cutter body 5 through the slots 20 and the tenons 6.

[0031] A support plate 21 is fixedly connected to the upper surface of the base 16. Two sliding rods 22 are fixedly connected to the support plate 21.

[0032] The implementation principle is as follows: The fourth motor is started, and its output drives the third drive rod 23 to rotate. The third drive rod 23 moves the movable shell 24, releasing the seal on the bottom shell 18. The second motor is started, and its output drives the first drive rod 14 to rotate. The first drive rod 14 lowers the support arm 2 and other components, causing the latch 6 to align with a slot 20. The third motor is started, and its output drives the second drive rod 17 to rotate. The second drive rod 17 moves the column 1 and other components horizontally towards the cutter head 19, causing the latch 6 to enter the slot 20. The air spring is started, and its output drives the pressure block 10 to slide downwards. The pressure block 10 slides the insertion block 8 through the support rod 9, causing the insertion block 8 to disengage from the slot 7. The second motor is controlled to reverse, and the first drive rod 14 raises the support arm 2 and other components, causing the support shaft 4 to disengage from the cutter body 5. The stepper motor is started, and its output drives the cutter head 19 to rotate, causing another cutter body 5 to align with the support shaft 4.
