Description

Technical Field

[0001] The invention belongs to the technical field of drilling machines, and in particular relates to horizontal deep hole drilling equipment. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the main motion is rotation of the drill bit, and the axial movement of the drill bit is the feed motion. When it is necessary to process a deep hole of 100mm to 200mm on the side of a plate-like material, the plate-like material is usually placed horizontally on the workbench, and then the drill bit is fed horizontally during the rotation process. After drilling to the specified depth, the drill bit is pulled back; the above process is repeated until a hole of the corresponding depth is processed on the plate-like material. It should be noted that the specified depth is the depth of the drill bit drilling at one time, and the corresponding depth on the plate-like material is the depth of the final hole; due to the long drilling depth, in order to ensure processing safety, the drill bit needs to drill multiple times and finally process a hole of the corresponding depth.

[0003] Since the drilling depth is long, the free end of the drill bit is longer; when the drill bit just starts drilling, the drill bit will shake radially, and in severe cases the drill bit will break, posing a safety hazard. Summary of the invention

[0036] The present invention provides a horizontal deep hole drilling device. Compared with the prior art, the limiting component 3 is clamped on the material. When the drill bit 5 passes through the limiting component 3 and drills a hole in the material, the limiting component 3 can play a role of circumferential limiting on the drill bit 5, thereby reducing the shaking of the drill bit 5 at the beginning of drilling, thereby reducing the possibility of the drill bit 5 breaking and reducing safety hazards; by moving the moving frame 2 along the X direction and the Y direction, the moving frame 2 can be moved to a specified position on the horizontal plane; by driving the motor 4 to move along the height direction, the drill bit 5 can be moved to a specified height.

[0037] Exemplarily, the workbench 1 has a first area 11 for placing materials and a second area 12 for placing the mobile rack 2, and the height of the second area 12 is lower than that of the first area 11; the second area 12 is provided with a first slide rail 13 arranged along the width direction of the workbench 1, and there are two first slide rails 13, and the two first slide rails 13 are respectively arranged at both ends of the second area 12 arranged along the length direction of the workbench 1. The two first slide rails 13 are both slidably provided with a first slider 14, and the two first sliders 14 are connected together by a second slide rail 15, and the mobile rack 2 is slidably matched with the second slide rail 15 through a second slider 21 arranged at the bottom thereof; there are two second slide rails 15.

[0039] Exemplarily, the two first sliders 14 are respectively provided with a limit plate 141, and the limit plate 141 is rotatably provided with a second screw 18, and the positions of the second screw 18 and the limit plate 141 are relatively fixed; the protrusion 22 has a threaded hole that is threadedly matched with the second screw 18, and the first screw 17 and the second screw 18 are not at the same height, and the first screw 17 and the second screw 18 are perpendicular to each other, so the protrusion 22 can be provided with threaded holes that are perpendicular to each other and not at the same height. By rotating the second screw 18, the mobile frame 2 can slide along the direction of the second slide rail 15.

[0040] Exemplarily, the top of the mobile frame 2 has a support plate 6, on which a third slide rail 61 is provided, and a third slider 62 that slides with the third slide rail 61 is fixedly provided on the side of the drive motor 4; a sleeve 63 is fixedly provided on the support plate 6, and a third screw 64 is rotatably provided in the sleeve 63, and the positions of the third screw 64 and the sleeve 63 are relatively fixed; and a threaded sleeve 41 that threads with the third screw 64 is provided on the outer wall of the drive motor 4.

[0041] It should be noted that the first screw rod 17 is provided with top screw holes on both sides of the driving frame 16, and top screws are provided in the top screw holes; after the first screw rod 17 is installed in place, a part of the top screw is screwed out of the top screw hole, at this time, the two top screws can play the role of axial limiting the first screw rod 17, so that the positions of the first screw rod 17 and the driving frame 16 are relatively fixed. The limiting method of the second screw rod 18 and the limiting plate 141 is the same as the limiting method of the first screw rod 17 and the driving frame 16, and the limiting method of the third screw rod 64 and the sleeve 63 is the same as the limiting method of the first screw rod 17 and the driving frame 16, which will not be repeated here.

[0042] In addition, the first area 11 of the workbench 1 is provided with a plurality of U-shaped clamps 19, each of which is provided with a threaded hole, and a clamping bolt 191 is provided at the position of the threaded hole of the U-shaped clamp 19; after the material is placed on the workbench 1, the position of the material is adjusted first, and after the position of the material is determined, the U-shaped clamp 19 is clamped on the workbench 1 and the material, and the material is clamped by rotating the clamping bolt 191; in the above manner, the material can be fixed on the workbench 1.

[0043] Exemplarily, a pressure plate 192 may be provided between the material and the clamping bolt 191 , and the clamping bolt 191 clamps the pressure plate 192 , so that the pressure plate 192 clamps against the material, thereby increasing the clamping area and reducing the possibility of scratching the material.

[0044] In some embodiments, Figures 1 to 8 As shown, the limiting component 3 includes a limiting shell 32 and two groups of clamps 33; the open end of the limiting shell 32 is used to contact the side wall of the material; the other end of the limiting shell 32 has a limiting hole 321 for the drill bit 5 to pass through, and the limiting hole 321 can circumferentially limit the drill bit 5; the two groups of clamps 33 are respectively arranged at the top and bottom of the limiting shell 32; the two groups of clamps 33 have the freedom to slide along the height direction, and the two groups of clamps 33 can clamp the material.

[0045] It should be noted that the limiting shell 32 clamps the material through two sets of clamps 33, and during the drilling process, the positions of the limiting shell 32 and the material can be ensured to remain relatively unchanged; during multiple drilling and retraction processes of the drill bit 5, the drill bit 5 will not be completely pulled out of the limiting shell 32.

[0046] In some embodiments, Figures 1 to 8 As shown, the top and bottom of the limiting shell 32 are connected to a prism structure 34, and the prism structure 34 is arranged along the height direction; each group of clamps 33 has a sliding hole that slides with the prism structure 34; an elastic component 35 is sleeved on the prism structure 34, one end of the elastic component 35 is connected to the clamp 33, and the other end of the elastic component 35 is connected to the top of the prism structure 34.

[0047] Exemplarily, the splint 33 is slidably matched with the prismatic structure 34, which can guide the splint 33 on the one hand and limit the circumferential rotation of the splint 33 on the other hand; the elastic component 35 includes a spring, and a limiting cap 36 is sleeved on the top of the prismatic structure 34. The outer peripheral wall of the limiting cap 36 has a first connecting hole, and the side wall of the prismatic structure 34 has a second connecting hole. The first connecting hole and the second connecting hole are plug-in matched by a pin shaft to fix the limiting cap 36 on the prismatic structure 34.

[0048] It should be noted that, by providing elastic force to the clamping plate 33 through the elastic component 35 , the clamping plate 33 can clamp the material, thereby fixing the limiting shell 32 on the side wall of the material.

[0049] In some embodiments, Figures 1 to 8 As shown, the free end of the clamping plate 33 has an inclined surface 331, and the inclined surface 331 of the clamping plate 33 first contacts the edge of the material to make the clamping plate 33 move away from the material, and finally make the clamping plate 33 clamp the material.

[0050] It should be noted that, by providing the inclined surface 331 on the clamping plate 33 , it is convenient for the clamping plate 33 to move to the top or bottom of the material, thereby facilitating the clamping plate 33 to clamp the material, so that the limiting shell 32 is fixed on the material.

[0051] In some embodiments, Figures 1 to 8 As shown, each group of clamps 33 has threaded holes, and the limiting component 3 also includes a preset bolt 37, which is threadedly matched with the clamps 33; wherein the threaded end of the preset bolt 37 is used to abut the outer wall of the limiting shell 32 to enable the clamps 33 to match materials of different thicknesses.

[0052] It should be noted that by arranging a preset bolt 37 on the clamping plate 33, the distance between the threaded end of the preset bolt 37 and the limiting shell 32 can be adjusted, thereby adjusting the initial position between the clamping plate 33 and the limiting shell 32, so that the limiting shell 32 can adapt to materials of different thicknesses; through the above-mentioned setting, the limiting shell 32 can clamp materials of different thicknesses.

[0053] In some embodiments, Figures 1 to 8 As shown, a brush 38 is detachably provided in the accommodating cavity 31 of the limiting shell 32 , and the brush 38 is arranged along the circumference of the limiting hole 321 ; wherein the brush 38 is used to clean the debris on the drill bit 5 .

[0054] It should be noted that a connecting ring 322 is provided inside the limiting shell 32, a brush 38 is fixed on the inner circumferential wall of the connecting ring 322, the connecting ring 322 is fixed inside the limiting shell 32 by bolts, and the connecting ring 322 is coaxially arranged with the drill bit 5; when the drill bit 5 retracts, the debris on the drill bit 5 can be cleaned off by the brush 38, thereby reducing the debris adhering to the drill bit 5.

[0055] In some embodiments, Figures 1 to 8 As shown, the limiting component 3 has a discharge pipe 39 connected to the accommodating chamber 31, and the discharge pipe 39 is connected to the exhaust fan through a hose; a filter is provided at the connection position between the hose and the exhaust fan.

[0056] For example, by starting the exhaust fan, suction can be provided to the limiting shell 32, thereby sucking away the debris in the accommodating chamber 31; the debris can be intercepted by setting a filter. There is no need to seal between the limiting shell 32 and the material side wall, so the external airflow can pass through the gap between the limiting shell 32 and the material side wall.

[0057] Exemplarily, a notch may also be provided at the top of the open end of the limiting shell 32 to facilitate airflow into the limiting shell 32 through the notch when the exhaust fan is started.

[0058] Exemplarily, the filter is fixed in the mounting cylinder, one end of the mounting cylinder is threadedly engaged with the hose, and the other end of the mounting cylinder is sleeved on the air intake port of the exhaust fan; through the above arrangement, when the exhaust fan is started, debris can be sucked into the mounting cylinder and filtered through the filter; after the drilling is completed, the mounting cylinder is removed from the hose to facilitate subsequent processing of the debris in the mounting cylinder.

[0059] In some embodiments, Figures 1 to 8 As shown, a first guide portion 42 is provided on the side wall of the driving motor 4, and a second guide portion 7 is provided on the limiting component 3; the first guide portion 42 has a through hole aligned with the second guide portion 7, and the second guide portion 7 has a guide rod 71 slidably matched with the first guide portion 42; wherein a baffle 43 is slidably provided on the first guide portion 42, and the baffle 43 has a first state in which it abuts against the end of the guide rod 71, and a second state in which it is separated from the end of the guide rod 71.

[0060] It should be noted that the guide rod 71 is fixed on the second guide part 7, and the second guide part 7 is fixed on the limit shell 32; through the above arrangement, the limit shell 32 is sleeved on the drill bit 5, and the limit shell 32 is slidably matched with the first guide part 42 through the guide rod 71, which can avoid the limit shell 32 from rotating, thereby facilitating the clamping plate 33 on the limit shell 32 to clamp the material.

[0061] Before starting to drill, the drill bit 5 moves toward the material. At this time, the baffle 43 abuts against the end of the guide rod 71 in order to provide support for the guide rod 71 so that the open end of the limit shell 32 slides to the side wall position of the material and the clamping plate 33 on the limit shell 32 clamps the material; to avoid relative displacement between the guide rod 71 and the first guide portion 42 when the clamping plate 33 contacts the material.

[0062] When the limit shell 32 moves into place and the clamp 33 clamps the material, the baffle 43 is separated from the end of the guide rod 71. At this time, the baffle 43 does not provide support for the guide rod 71; when the drill bit 5 moves toward the material direction and drills a hole, the position of the guide rod 71 remains unchanged, and the first guide part 42 slides on the guide rod 71.

[0063] Exemplarily, a limiting ring 72 is sleeved on one end of the guide rod 71 passing through the first guide portion 42, a threaded hole is provided on the outer peripheral wall of the limiting ring 72, and a tightening bolt is provided on the limiting ring 72; after the limiting ring 72 is sleeved on the guide rod 71, the guide rod 71 is tightened by the tightening bolt, so that the limiting ring 72 can be fixed on the guide rod 71; when the guide rod 71 and the first guide portion 42 slide relative to each other, the separation of the guide rod 71 and the first guide portion 42 can be reduced.

[0064] In some embodiments, Figures 1 to 8 As shown, the first guide portion 42 has a connecting protrusion 44, and the connecting protrusion 44 has a guide hole facing the guide rod 71, and the baffle 43 is slidably matched with the guide hole. The side of the baffle 43 facing the drive motor 4 is a limiting side, and the position of the baffle 43 close to the limiting side has a limiting protrusion 431, which is used to contact the side wall of the connecting protrusion 44 to limit the sliding position of the baffle 43.

[0065] It should be noted that, through the sliding cooperation between the baffle 43 and the connecting protrusion 44, the purpose of the baffle 43 abutting against or separating from the guide rod 71 can be achieved; by setting a limiting protrusion 431 on the baffle 43, the sliding position of the baffle 43 can be limited, and when the baffle 43 is separated from the guide rod 71, the situation where the baffle 43 slides out of the connecting protrusion 44 can be avoided.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
