Description

Technical Field

[0001] The present invention relates to the technical field of processing of bamboo-plastic fiber products, and particularly to a drilling machine device and processing technology for processing bamboo-plastic fiber products. Background Art

[0002] Bamboo-plastic fiber products are composite material products mainly made of bamboo fiber and plastic and processed through special processes. Bamboo-plastic fiber products are similar to wood, and in some application scenarios, bamboo-plastic fiber products can replace wood, such as for making interior decoration boards or furniture parts, etc. In the production and processing of bamboo-plastic fiber products, in order to meet the functional and assembly requirements of the products, it is necessary to drill holes in the bamboo-plastic fiber products through existing drilling machine devices.

[0003] Among them, when drilling holes at the bottom of a cylindrical bamboo-plastic fiber product, the cylindrical bamboo-plastic fiber product is placed upside down (i.e., the opening is downward) on the workbench and fixed with an existing fixture, and then the drill bit of the drilling machine device moves down to drill holes at the bottom of the cylindrical bamboo-plastic fiber product. However, at this time, the drilling position of the cylindrical bamboo-plastic fiber product is far from the workbench surface and far from the contact area between the cylindrical bamboo-plastic fiber product and the workbench surface. Also, because the structural hardness of bamboo fiber is relatively low compared to other hard plates, this makes that during the drilling process, the drilling part lacks sufficient support and restraint, and the drill bit pressure easily causes displacement and deformation at the drilling position, thereby leading to problems such as cracking.

[0004] At the same time, bamboo-plastic fiber is a composite material of bamboo fiber and plastic. Bamboo fiber itself has a certain fiber structure, and during the drilling process, the fiber is easily torn, and the plastic component is also easily stretched under the action of high temperature and mechanical force. Therefore, when the drill bit passes through the cylindrical bamboo-plastic fiber product, these factors combined are likely to cause the inside of the hole to be uneven and form burrs, affecting the quality of the drilled hole. Summary of the Invention

[0037] The locking mechanism includes four jacks 36 and four bolts 21. The four bolts 21 are movably and annularly arrayed around the center of the connecting cylinder 18 and penetrate through the inner wall of the connecting cylinder 18.

[0039] The deburring mechanism includes two guide grooves 32 which are symmetrically arranged at the upper end of the connecting cylinder 18. Vertical blocks 24 are respectively and closely arranged on the inner walls of the two guide grooves 32 near the axis line of the connecting cylinder 18. Connecting columns 22 are fixedly connected to the mutually remote walls of the two vertical blocks 24. Both connecting columns 22 movably penetrate through the connecting cylinder 18.

The second push block 33 is closely arranged between the two vertical blocks 24.

[0041] A cylindrical cover 15 is fixedly connected to the upper end of the base 4. The cylindrical cover 15 corresponds to the cross-shaped plate 12 in position. The telescopic shaft of the second electric push rod 14 penetrates through the cylindrical cover 15.

[0042] Working principle: The gantry slide 1 can control the up and down, front and back, and left and right movement of the drill bit 2. This is a well-known prior art and will not be elaborated here. First, drive the drill bit 2 away from the four support columns 11 by the gantry slide 1. Then, place the cylindrical bamboo plastic fiber product 5 upside down (i.e., the opening is downward) on the base 4. At this time, the solid bottom of the cylindrical bamboo plastic fiber product 5 faces upward, and the inner top end of the cylindrical bamboo plastic fiber product 5 will be in contact with the upper ends of the four support columns 11. It should be noted that starting the second electric push rod 14 can drive the connecting cylinder 18 to move down or up. The connecting cylinder 18 can drive the cross-shaped plate 12 and the four support columns 11 to move down or up, so as to control the height of the four support columns 11. After the cylindrical bamboo plastic fiber products 5 of different heights are placed upside down on the base 4, the upper ends of the four support columns 11 can be in contact with the inner top ends of the cylindrical bamboo plastic fiber products 5 of different heights. At this time, the cylindrical bamboo plastic fiber product 5 is jointly supported by the base 4 and the four support columns 11.

[0043] Subsequently, two first electric push rods 7 are activated. The two first electric push rods 7 can drive the respective connected sliding plates 13 to move in the corresponding sliding grooves 3 towards the direction of the tubular bamboo plastic fiber product 5. The two sliding plates 13 can drive the respective connected V-shaped plates 6 to move towards the direction of the tubular bamboo plastic fiber product 5. Until the two rollers 10 on the two V-shaped plates 6 are both in close contact with the outer wall of the tubular bamboo plastic fiber product 5, the tubular bamboo plastic fiber product 5 can be fixed. Subsequently, the gantry slide 1 is used to control the movement of the drill bit 2 to correspond to the center of the tubular bamboo plastic fiber product 5, as Figure 3 shown, that is, drill a hole at the bottom center of the tubular bamboo plastic fiber product 5. If it is necessary to drill holes at other positions at the bottom of the tubular bamboo plastic fiber product 5 or drill multiple holes, the telescopic shaft of one first electric push rod 7 contracts, and the telescopic shaft of the other first electric push rod 7 extends. Then, the front and back positions of the tubular bamboo plastic fiber product 5 on the base 4 can be changed. At the same time, two braking motors 8 on each V-shaped plate 6 are activated. Each braking motor 8 can drive the roller 10 to rotate. Then, under the friction force between the four rollers 10 and the tubular bamboo plastic fiber product 5, the tubular bamboo plastic fiber product 5 can be driven to rotate between the four rollers 10, so as to facilitate drilling holes at other positions at the bottom of the tubular bamboo plastic fiber product 5 or drilling multiple holes.

[0044] When drilling a hole at the bottom center of the tubular bamboo plastic fiber product 5, the gantry slide 1 is used to drive the drill bit 2 to move downward, and the drill bit 2 will rotate at a high speed, so as to drill a hole at the bottom center of the tubular bamboo plastic fiber product 5. Since the four support columns 11 are close to the drill bit 2, and the four support columns 11 are arranged around the drill bit 2, and the four support columns 11 are fixed to the base 4 through the cross-shaped plate 12 and the second electric push rod 14, etc., so that during the drilling process of the bottom of the tubular bamboo plastic fiber product 5, the drilled part has sufficient support and restraint, avoiding displacement and deformation at the drilling position due to the pressure of the drill bit 2, and avoiding problems such as cracking.

[0045] After the drilling is completed, start the electric push rod three 34 to drive the first push block 29 to move downward. The four third springs 27 were originally in a compressed state. Then, under the action of the third springs 27, the four triangular blocks 28 will continuously move closer to the first push block 29, and the inclined surfaces of the four triangular blocks 28 will always be respectively in contact with the upper four edges of the first push block 29. The four triangular blocks 28 can drive the pins 21 connected to them to move together until the four pins 21 respectively leave the jacks 36 outside the four columns 11. At this time, because the four first springs 16 were also originally in a compressed state, after the four columns 11 lose the restriction of the corresponding pins 21, under the action of the four first springs 16, the four first springs 16 can push the discs 17 connected to them to move downward. The four discs 17 can drive the columns 11 connected to them to slide down in the cross-shaped plate 12, so the upper ends of the four columns 11 will move away from the inner top end of the tubular bamboo plastic fiber product 5. At this time, start the electric push rod two 14 to drive the connecting cylinder 18, the cross-shaped plate 12, the four columns 11, the two polishing columns 19, etc. to move upward together until the two polishing columns 19 pass through the drilled holes and the polishing blocks 20 outside the two polishing columns 19 are in contact with the inner top end of the tubular bamboo plastic fiber product 5. At this time, the upper ends of the four columns 11 will move upward to be close to the inner top end of the tubular bamboo plastic fiber product 5 and not contact it.

[0046] It should be noted that when the first pushing block 29 moves downward, it will also drive the concave plate 30 and the second pushing block 33 to move downward together. The second pushing block 33 will first move downward between the two vertical blocks 24 until the four support columns 11 lose the restriction of the corresponding pins 21, that is, when the upper ends of the four support columns 11 are far from the inner top end of the cylindrical bamboo plastic fiber product 5. At this time, the second pushing block 33 will move downward to be close to the first inclined block 25 and the second inclined block 31. When the two grinding columns 19 move upward through the drilled holes and the grinding blocks 20 outside the two grinding columns 19 are in contact with the inner top end of the cylindrical bamboo plastic fiber product 5, if the first pushing block 29 is continuously driven to move downward at this time, the two ends of the first pushing block 29 will respectively squeeze the first inclined block 25 and the second inclined block 31. Under the action of the extrusion force, the first inclined block 25 and the second inclined block 31 will move away from each other, and the second inclined block 31 is in sliding fit with the card slots 26 on the first inclined block 25, then it will drive the two vertical blocks 24 to move away from each other. Each vertical block 24 will slide in the corresponding guide groove 32 and drive the corresponding connecting column 22 to slide outward in the connecting cylinder 18, and each vertical block 24 will squeeze the second spring 23 connected to the corresponding guide groove 32. When the two vertical blocks 24 move away from each other, the two grinding columns 19 will also move away from each other until the two grinding columns 19 are in contact with the inner wall of the drilled holes. At this time, the four braking motors 8 are started to drive the four rollers 10 to rotate rapidly, then the cylindrical bamboo plastic fiber product 5 will also rotate rapidly, and the burrs on the inner side of the drilled holes will continuously rub against the two grinding columns 19, and the burrs on the lower edge of the drilled holes will continuously rub against the grinding blocks 20, so as to more thoroughly remove the burrs existing in the drilled holes and improve the quality of the drilled holes.

[0047] It should be noted that after the tubular bamboo-plastic fiber product 5 is drilled, the two V-shaped plates 6 are moved away from the tubular bamboo-plastic fiber product 5, loosened and taken away. Subsequently, the second electric push rod 14 is activated to drive the connecting cylinder 18, the cross-shaped plate 12, the four support columns 11, etc. to move downward until the discs 17 under the four support columns 11 are pressed against the upper end surface of the cylindrical cover 15. At this time, the four discs 17 and the four support columns 11 will remain stationary relative to the cylindrical cover 15, and the connecting cylinder 18 and the cross-shaped plate 12 will continue to move downward. The connecting cylinder 18 will compress the four first springs 16 until the four pins 21 on the connecting cylinder 18 move downward to correspond to the jacks 36 outside the four support columns 11 respectively. At this time, the third electric push rod 34 is activated to drive the first push block 29 and the concave plate 30 to move upward. The first push block 29 will press against the inclined surfaces of the four triangular blocks 28 and maintain a sliding fit with them. Under the action of the pressing force, the four triangular blocks 28 move synchronously in a direction away from the axis of the connecting cylinder 18, thereby driving the end parts of the four pins 21 to be inserted into the four jacks 36 respectively. The third springs 27 connected between each triangular block 28 and the inner wall of the connecting cylinder 18 will be compressed again. The upward movement of the concave plate 30 will drive the second push block 33 to move upward between the first inclined block 25 and the second inclined block 31. Under the action of the second spring 23, the first inclined block 25 and the second inclined block 31 will move closer to each other, and the two vertical blocks 24 and the two grinding columns 19 will also move closer to each other until the second push block 33 moves upward between the two vertical blocks 24. The first inclined block 25, the second inclined block 31, the two vertical blocks 24 and the two grinding columns 19 will all return to the state as shown in Figure 6 the figure, and at this time, the four support columns 11 are restricted by the corresponding pins 21 and fixed in the cross-shaped plate 12, which is convenient for supporting the next tubular bamboo-plastic fiber product 5.

[0048] It should also be noted that a grinding disc can be fixedly sleeved outside the drill rod of the drill bit 2. When the drill bit 2 drills through the tubular bamboo-plastic fiber product 5, the drill bit 2 will not contact the two grinding columns 19. The drill bit 2 can continue to rotate and move downward until the grinding disc outside the drill bit 2 rotates and fits against the bottom of the tubular bamboo-plastic fiber product 5 and rotates, then the burrs on the upper edge of the drilled hole can be ground and removed.

[0049] It should also be noted that according to the adjustability of the two grinding columns 19, the two grinding columns 19 can also grind and remove burrs from holes of different sizes.

[0050] Please refer to Figure 1 - Figure 8 , the present invention also discloses a processing technology for bamboo-plastic fiber products, including the following steps:

[0051] S1: First, the tubular bamboo-plastic fiber product 5 is buckled on the upper end of the base 4, and then the tubular bamboo-plastic fiber product 5 is fixed through the mutual cooperation of the clamping mechanism and the rolling mechanism;

[0052] S2: Then, start the second electric push rod 14, which can drive the connecting cylinder 18, the cross-shaped plate 12 and the four support columns 11 to move upward together until the upper ends of the four support columns 11 are in contact with the inner top of the cylindrical bamboo-plastic fiber product 5. At this time, the centers among the four support columns 11, the center of the connecting cylinder 18, the center of the cylindrical bamboo-plastic fiber product 5 and the center of the drill bit 2 are on the same line, realizing the positioning of drilling.

[0053] S3: Then, start the gantry slide 1, which can drive the drill bit 2 to move downward and drill the top of the cylindrical bamboo-plastic fiber product 5.
