Description

Technical Field

[0001] The present invention relates to the technical field of bar processing, and particularly to a processing device and a processing method for straight-edge holes of stainless steel bars. Background Art

[0002] Stainless steel bars are a kind of materials commonly used in manufacturing and construction, with advantages such as corrosion resistance, high strength, and good processing performance, and are widely used in fields such as machinery, construction, medical equipment, and food processing. The processing of stainless steel bars mainly includes cutting, drilling, milling, turning, and welding.

[0003] Among them, when drilling axially on stainless steel bars, it is sometimes necessary to drill straight-edge holes. Most of the time, milling is used to process the straight-edge holes of the positioned stainless steel bars. During processing, the high-speed rotating milling cutter penetrates into the stainless steel bar for processing. However, for some longer stainless steel bars, the milling cutter needs to penetrate a longer depth. At this time, waste chips are easily stuck inside the stainless steel bar, causing blockage, affecting the penetration of the milling cutter, and easily causing the milling cutter to tilt and break, resulting in the bending and skewing of the drilled hole. For this reason, we propose a processing device and a processing method for straight-edge holes of stainless steel bars to solve the above problems. Summary of the Invention

[0034] The processing mechanism 4 includes a mechanism outer frame 41. A bearing 411 is fixedly clamped at the top of the mechanism outer frame 41. A rotating shaft 42 is fixedly clamped in the middle of the bearing 411. A milling cutter head 43 is fixedly installed at one end of the rotating shaft 42. The milling cutter head 43 is in the shape of a frustum. An auxiliary shaft 44 is rotatably installed at the bottom of the mechanism outer frame 41. A first sprocket 45 is fixedly installed at the end of the rotating shaft 42 away from the milling cutter head 43. A second sprocket 451 is fixedly installed on the outer side of the auxiliary shaft 44. A drive chain 452 is meshed and connected to the outer sides of the first sprocket 45 and the second sprocket 451.

[0035] A first motor 453 is fixedly installed in the mechanism outer frame 41. The drive end of the first motor 453 and one end of the auxiliary shaft 44 are fixedly installed. By controlling the first motor 453 to start and drive the auxiliary shaft 44 to rotate, and cooperating with the meshing connection of the first sprocket 45, the second sprocket 451 and the drive chain 452, the rotating shaft 42 and the milling cutter head 43 are driven to rotate at high speed. Two cross-sliding frames 46 are slidably clamped in the middle of the side of the mechanism outer frame 41 away from the milling cutter head 43. Positioning wheels 461 are rotatably installed at the ends of the two cross-sliding frames 46 away from the mechanism outer frame 41. By arranging the two positioning wheels 461, it is convenient to perform internal support positioning on the processing mechanism 4 subsequently, so as to improve the stability of the processing mechanism 4 for deep processing of stainless steel bars.

[0036] Optionally, connecting longitudinal frames 462 are vertically installed at the ends of the two cross-sliding frames 46 away from the positioning wheels 461. A telescopic cylinder 463 is fixedly installed in the mechanism outer frame 41. The drive end of the telescopic cylinder 463 and the middle of the connecting longitudinal frame 462 are fixedly installed. By controlling the telescopic cylinder 463 to start and drive the connecting longitudinal frame 462 to control the horizontal movement of the two cross-sliding frames 46, the positioning wheels 461 are driven to move horizontally. This is convenient for adapting to different processing sizes.

[0037] Optionally, a drive gear 11 is movably clamped at the top of one of the mounting longitudinal frames 1. A drive shaft 111 is fixedly installed in the middle of the drive gear 11. The drive shaft 111 is rotatably installed at the top of the mounting longitudinal frame 1. A driven rack 12 for cooperating with the drive gear 11 is provided at the side end of the lifting sliding frame 3. The drive gear 11 and the driven rack 12 are meshed and connected.

[0038] Preferably, a driven worm gear 112 is fixedly installed at one end of the drive shaft 111. A drive worm 113 is meshed on the outer side of the driven worm gear 112. The drive worm 113 is rotatably installed outside the mounting longitudinal frame 1.

[0039] Preferably, a second motor 114 is fixedly installed on one side of the outer wall of the longitudinal frame 1 close to the driving worm 113, and the driving end of the second motor 114 is fixedly installed with one end of the driving worm 113. By controlling the second motor 114 to start, the driving worm 113 is controlled to drive the driven worm wheel 112 to rotate, and then the driving shaft 111 and the driving gear 11 are controlled to rotate. Cooperating with the meshing connection between the driving gear 11 and the driven rack 12, the lifting carriage 3 is driven to slide up and down in the driving outer frame 2, so as to control the processing mechanism 4 to slide up and down.

[0040] Optionally, a connecting bracket 5 is fixedly installed at the bottom end of the mechanism outer frame 41, and a connecting slot 301 corresponding to the connecting bracket 5 is opened at the top end of the lifting carriage 3. The connecting bracket 5 is fixedly clamped in the connecting slot 301 by bolts. This facilitates the disassembly of the lifting carriage 3 and the processing mechanism 4.

[0041] Preferably, there are multiple lifting carriages 3. A connecting slot 301 is opened at the top end of each lifting carriage 3, and a connecting bracket 5 is provided at the bottom end of each lifting carriage 3 for clamping between two adjacent lifting carriages 3. In this way, different numbers of lifting carriages 3 can be installed according to the drilling depth of the stainless steel bar, which is convenient for adjusting the distance of the processing mechanism 4 to penetrate into the processing.

[0042] The present invention also provides a processing method for straight-edge holes of stainless steel bars, and the steps are as follows:

[0043] First, as Figure 1 shown, the stainless steel bar 101 is vertically positioned by an external fixing device.

[0044] Then, as Figure 6 shown, an external drilling mechanism is used to vertically drill an auxiliary round hole 7 at an eccentric position of the stainless steel bar 101.

[0045] Subsequently, according to the drilling depth of the stainless steel bar 101, a lifting carriage 3 with a suitable length is selected for the processing device 100 of the straight-edge hole of the stainless steel bar. For example, a certain number of lifting carriages 3 are spliced as needed in the above-mentioned processing device 100 of the straight-edge hole of the stainless steel bar, which is convenient for adjusting the distance of the processing mechanism 4 to penetrate into the processing.

[0046] Next, control the first motor 453 of the processing device 100 of the straight-edge hole of the stainless steel bar to start, and drive the auxiliary shaft 44 to rotate in cooperation with the meshing connection between the first sprocket 45, the second sprocket 451 and the transmission chain 452, so as to drive the rotating shaft 42 and the milling cutter head 43 to rotate at high speed.

[0047] Meanwhile, control the second motor 114 to start, control the driving worm 113 to drive the driven worm wheel 112 to rotate, and then control the driving shaft 111 and the driving gear 11 to rotate. Cooperate with the meshing connection between the driving gear 11 and the driven rack 12 to drive the lifting carriage 3 to slide upward in the driving outer frame 2, thereby controlling the processing mechanism 4 to slide upward, making the milling cutter head 43 rotate at a high speed and move upward, and milling a straight hole on one side of the auxiliary round hole 7 in the stainless steel bar. At the same time, control the telescopic cylinder 463 to start, drive the connecting longitudinal frame 462 to control the two cross carriages 46 to move horizontally, thereby driving the positioning wheel 461 to move horizontally, making the outer wall of the positioning wheel 461 contact the inner wall of the auxiliary round hole 7, and sequentially realizing the internal support positioning of the processing mechanism 4 in the stainless steel bar 101. This can improve the stability of the processing mechanism 4 when it penetrates into the stainless steel bar for processing, and prevent the processing mechanism 4 from shifting during deep drilling processing, resulting in bent and inclined holes, thereby improving the quality of the drilling. Moreover, the waste chips generated by milling and drilling are discharged through the auxiliary round hole 7, thereby preventing the waste chips from getting stuck in the stainless steel bar and causing blockage, affecting the deep penetration of the milling cutter head 43.

[0048] Finally, after the milling of the straight hole is completed, use an external milling mechanism to mill other parts between the auxiliary round hole 7 and the already milled straight hole to form a straight-edge hole position 701.

It must be pointed out that the disclosed embodiments do not limit the scope of the present invention.
