Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe processing technology, specifically to a positioning device for drilling stainless steel pipes. Background Technology

[0002] Stainless steel pipes are widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Additionally, they are lighter in weight while maintaining the same bending and torsional strength, making them widely used in the manufacture of mechanical parts and engineering structures. They are also commonly used in furniture and kitchenware. The processing of stainless steel pipes requires drilling holes at different locations within the pipe body.

[0003] Currently, Chinese patent application number CN202122079205.1 discloses a positioning device for drilling stainless steel pipes, including a placement frame and multiple drive plates. The drive plates are slidably connected in a first sliding groove opened in the placement frame. A blocking plate is provided on one side of the placement frame. An arc-shaped placement seat for supporting the steel pipe is provided at the center of the drive plate. Two positioning plates are also provided on the drive plate. The positioning plates are symmetrically arranged on both sides of the arc-shaped placement seat along the sliding direction of the drive plate. The drive plate is provided with a sliding adjustment mechanism for adjusting the distance between the opposite surfaces of the positioning plates. Clamping components for clamping the steel pipe are symmetrically arranged on the opposite surfaces of the positioning plates.

[0004] The above application solves the problem that traditional positioning devices for drilling stainless steel pipes only use a single fixing ring for short-distance clamping and fixing, and the hole diameter of the fixing ring is not adjustable. When drilling stainless steel pipes with different hole diameters, it is necessary to replace the fixing ring with a different hole diameter, which is inconvenient.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] A positioning device for drilling stainless steel pipes, such as Figure 1 It includes a fixing plate 1 for placing steel pipes and a first plate 2 set on the fixing plate 1. The first plate 2 is provided with a first clamping plate and a second clamping plate. The first plate 2 is provided with an adjusting member for adjusting the distance between the first clamping plate and the second clamping plate. The first clamping plate and the second clamping plate are used to clamp and position the steel pipes on the fixing plate 1. The top four corners of the fixing plate 1 are provided with mounting bolts 3.

[0033] like Figure 1 Place the steel pipe on the fixing plate 1, so that one end of the steel pipe is between the first clamping plate and the second clamping plate. Then, adjust the distance between the first clamping plate and the second clamping plate using the adjusting piece on the first plate 2 until both the first clamping plate and the second clamping plate are pressed against the side wall of the steel pipe to clamp and position the steel pipe. By adjusting the distance between the first clamping plate and the second clamping plate using the adjusting piece, steel pipes of different sizes can be clamped. The fixing plate 1 can be easily installed on the worktable of the drilling machine by using the mounting bolt 3, which facilitates the drilling of the steel pipe by the drill bit of the drilling machine. It is simple and convenient to use.

[0034] like Figure 1 and Figure 2 The adjusting component includes a movable plate 4 and an embedded groove 5 set at the top of the fixed plate 1. A first plate 2 is set at the bottom of the embedded groove 5, and the top of the first plate 2 is flush with the top of the fixed plate 1. A long strip first baffle 6 and a second baffle 7 are provided on both sides of the top of the first plate 2. The first baffle 6 is located on one side of the second baffle 7 and the length direction of the first baffle 6 is perpendicular to the length direction of the second baffle 7. The movable plate 4 is located at the top of the first plate 2, and a first clamping plate 8 and a second clamping plate 9 are obliquely provided on opposite sides of the movable plate 4. The first clamping plate 8 is opposite to the first baffle 6, and the second clamping plate 9 is opposite to the second baffle 7. A steel pipe is located between the first baffle 6 and the first clamping plate 8 or between the second baffle 7 and the second clamping plate 9. The first plate 2 is provided with a pushing component for pushing the movable plate 4 to move the first clamping plate 8 and the second clamping plate 9 closer to the first baffle 6 and the second baffle 7. The first clamping plate 8, the second clamping plate 9, and the movable plate 4 are the first clamping plates, and the first baffle 6 and the second baffle 7 are the second clamping plates.

[0035] like Figure 1 and Figure 2 When the steel pipe is located between the first baffle 6 and the first clamping plate 8, and it is necessary to adjust the distance between the first clamping plate and the second clamping plate to clamp the steel pipe, simply push the moving plate 4 with the pushing component to move the first clamping plate 8 and the second clamping plate 9 towards the first baffle 6 and the second baffle 7 until the first clamping plate 8 contacts the steel pipe and presses the steel pipe firmly onto the first baffle 6, and the second clamping plate 9 abuts against the second baffle 7. At this time, the clamping of the steel pipe is completed. When there are two steel pipes, the two steel pipes are located between the first baffle 6 and the first clamping plate 8 and between the second baffle 7 and the second clamping plate 9, respectively. At this time, the pushing component pushes the moving plate 4 to move the first clamping plate 8 and the second clamping plate 9 towards the first baffle 6 and the second baffle 7 until the first clamping plate 8 and the second clamping plate 9 both contact the steel pipe and press the two steel pipes firmly onto the first baffle 6 and the second baffle 7, respectively. At this time, the included angle between the two steel pipes is 90 degrees, and the clamping of two steel pipes can be completed at the same time. It is simple and convenient to use.

[0036] like Figure 1 and Figure 2The pushing component includes a mounting plate 10 and two mounting blocks 12 disposed on the first plate 2 away from the first baffle 6 and the second baffle 7. The two mounting blocks 12 are disposed opposite each other. The mounting plate 10 is bolted to the top of the two mounting blocks 12. A placement groove 13 is provided on one side of the moving plate 4 between the first clamping plate 8 and the second clamping plate 9. A push block 14 is rotatably connected between the top and bottom walls of the placement groove 13. A screw 15 is rotatably connected to the side of the push block 14 away from the bottom of the placement groove 13. The end of the screw 15 away from the push block 14 passes through the two mounting blocks 12. A threaded barrel 16 is threadedly connected to the screw 15. The threaded barrel 16 is located between the two mounting blocks 12 and a rotating shaft 17 is fixedly connected to the top of the threaded barrel 16. The rotating shaft 17 is rotatably connected to the mounting plate 10. A driving component for driving the screw 15 to rotate is provided on the first plate 2.

[0037] like Figure 1 and Figure 2 When it is necessary to push the moving plate 4 to move the first clamping plate 8 and the second clamping plate 9 towards the first baffle 6 and the second baffle 7, it is only necessary to drive the screw 15 to rotate through the driving component. At this time, the screw 15 and the threaded barrel 16 cooperate to push the push block 14 to move the moving plate 4, the first clamping plate 8, and the second clamping plate 9 towards the first baffle 6 and the second baffle 7. At this time, because the rotating shaft 17 on the threaded barrel 16 is rotatably connected to the mounting plate 10, and the push block 14 is rotatably connected between the top and bottom walls of the placement groove 13, when the first clamping plate 8 and the second clamping plate 9 move towards the first baffle 6 and the second baffle 7, the screw 15 pushes the push block 14 to move the moving plate 4, the first clamping plate 8, and the second clamping plate 9 towards the first baffle 6 and the second baffle 7. By cooperating with the screw 15 and the threaded rod, and with the screw 15, the push block 14, and the moving plate 4, two steel pipes of different diameters located between the first clamping plate 8 and the first baffle 6, and between the second clamping plate 9 and the second baffle 7, respectively, can be clamped and fixed simultaneously. When the two steel pipes are clamped between the first clamping plate 8 and the first baffle 6, and between the second clamping plate 9 and the second baffle 7, respectively, the first clamping plate 8 and the first baffle 6 are parallel, and the second clamping plate 9 and the second baffle 7 are parallel. When there is only one steel pipe and it is clamped between the first clamping plate 8 and the first baffle 6, the first clamping plate 8 and the first baffle 6 are parallel, and the second clamping plate 9 and the second baffle 7 are in contact. It is simple and convenient to use.

[0038] like Figure 1 and Figure 2The driving component includes a contact plate 18 and a first motor 19 mounted on the contact plate 18. One end of the rotating shaft of the first motor 19 is fixedly connected to one end of the screw 15 that passes through two mounting blocks 12. The contact plate 18 is placed on the fixed plate 1, and the bottom end of the contact plate 18 contacts the top end of the fixed plate 1. The purpose of this arrangement is that when it is necessary to drive the screw 15 to rotate, only the first motor 19 needs to be turned on. At this time, the rotating shaft of the first motor 19 drives the screw 15 to rotate. When the screw 15 rotates, the screw 15 pushes the push block 14 through the cooperation of the screw 15 and the threaded barrel 16, causing the moving plate 4, the first clamping plate 8, and the second clamping plate 9 to move towards the first baffle 6 and the second baffle 7. At the same time, the screw 15 drives the first motor 19 and the contact plate 18 to move towards the mounting plate 10. It is simple and convenient to use.

[0039] like Figure 3 and Figure 4 There are two first plates 2, and the two first plates 2 are respectively set on opposite sides of the fixed plate 1. Or the adjusting component includes two sliding plates 20 that are horizontally slidably connected to the side of the first plate 2 away from the fixed plate 1. The top of the two sliding plates 20 is flush with the top of the fixed plate 1 and each has a vertical plate 21. The two vertical plates 21 are respectively located on opposite sides of the steel pipe. The side of the two vertical plates 21 that is close to each other is vertically slidably connected to a slider 22 by a moving component. The side of the two sliders 22 that is close to each other is provided with an arc-shaped third clamping plate 23 that abuts against the outer wall of the steel pipe. The first plate 2 is provided with a driving component for simultaneously driving the two sliding plates 20 to move in the direction of mutual approach. One of the vertical plates 21 and the third clamping plate 23 on the first plate 2 is the first clamping plate, and the other vertical plate 21 and the third clamping plate 23 on the first plate 2 is the second clamping plate.

[0040] like Figure 3 and Figure 4 When it is necessary to adjust the distance between the first clamping plate and the second clamping plate to clamp the steel pipe, simply move the slider 22 and the third clamping plate 23 vertically up and down according to the diameter of the steel pipe, adjust the height of the third clamping plate 23 on the vertical plate 21 so that the two third clamping plates 23 are located on opposite sides of the steel pipe and directly facing the steel pipe. Then, move the two sliding plates 20 towards each other simultaneously through the driving component. At this time, the two sliding plates 20 respectively drive the two vertical plates 21 to move closer to each other until the third clamping plates 23 on the two vertical plates 21 are both pressed against the side wall of the steel pipe. At this time, the clamping and positioning of the steel pipe can be completed. It is simple and convenient to use.

[0041] like Figure 4The moving part includes a groove 24 vertically mounted on a vertical plate 21. A slider 22 is vertically slidably connected to the groove 24. A lead screw 25 is rotatably connected between the top and bottom walls of the groove 24, and one end of the lead screw 25 passes through the slider 22 and is threadedly connected to the slider 22. A second motor 26 is provided at the top of the vertical plate 21 to drive the lead screw 25 to rotate. The purpose of this setting is that when it is necessary to move the slider 22 and the third clamping plate 23 vertically up and down to adjust the height of the third clamping plate 23 on the vertical plate 21, it is only necessary to turn on the second motor 26. At this time, the rotating shaft of the second motor 26 drives the lead screw 25 to rotate. Since one end of the lead screw 25 passes through the slider 22 and is threadedly connected to the slider 22, and the slider 22 is vertically slidably connected to the groove 24, when the lead screw 25 rotates, it can push the slider 22 to move the third clamping plate 23 vertically up and down on the vertical plate 21, thereby adjusting the height of the third clamping plate 23 on the vertical plate 21. It is simple and convenient to use.

[0042] like Figure 4 The driving component includes a first rack 27 disposed along the length of the equalizing plate 20 at the bottom of the two racks 20, and two support columns 28 disposed on the first plate 2. The two support columns 28 are respectively located below the two first racks 27, and each support column 28 is rotatably connected to a rotating ring 29. The outer wall of each rotating ring 29 is provided with a fan-shaped plate 30, and the arc surface of the fan-shaped plate 30 is provided with a number of teeth 31 that mesh with the first rack 27 along the arc direction of the arc surface. The outer wall of each rotating ring 29 away from the fan-shaped plate 30 is provided with a first rod 32. The first plate 2 is vertically provided with a first cylinder 33 located below the two support columns 28, and the piston rod of the first cylinder 33 is horizontally provided with a second rod 34. The second rod 34 is located between the two first rods 32, and the opposite sides of the second rod 34 are hinged with third rods 35. The ends of the two third rods 35 away from the second rod 34 are connected to the first rods 32. 2. The hinge is designed so that when it is necessary to move the two slide plates 20 closer to each other at the same time, only the first cylinder 33 needs to be opened. At this time, the piston rod of the first cylinder 33 drives the second rod 34 to move vertically downward. Since the two third rods 35 are hinged to the second rod 34, and the ends of the two third rods 35 away from the second rod 34 are hinged to the first rod 32, when the piston rod of the first cylinder 33 drives the second rod 34 to move vertically downward, the two rotating rings 29 can be driven to rotate respectively through the cooperation of the second rod 34, the two third rods 35 and the two first rods 32. The two rotating rings 29 rotate in opposite directions. At this time, the two rotating rings 29 drive the sector plates 30 to rotate along the rotation axis of the rotating rings 29. At this time, the teeth 31 on the two sector plates 30 that mesh with the first rack 27 can simultaneously push the two first racks 27 to move the two slide plates 20 horizontally in the direction of moving closer to each other. It is simple and convenient to use.

[0043] like Figure 5 and Figure 6and Figure 7 and Figure 8 and Figure 9 There are two first plates 2, which are respectively set on opposite sides of the fixed plate 1. Alternatively, the adjusting component includes a first groove 36 on one side of the first plate 2 and two second grooves 37 at the top of the first plate 2 and communicating with the first groove 36. The two second grooves 37 are opposite each other, and each second groove 37 has a vertically sliding column 38 connected to it. The tops of the two sliding columns 38 extend vertically outside the second grooves 37 and are located on opposite sides of the steel pipe. A V-shaped side groove 39 penetrating the fixed plate 1 is opened above one side of the first plate 2. The bottom end is located within the side groove 39. Above each of the two sliding columns 38 on their adjacent sides, a trapezoidal pressure plate 40 is positioned above the steel pipe. One inclined surface of each pressure plate 40 faces the steel pipe and abuts against its outer wall. The bottom ends of both sliding columns 38 extend vertically into the first groove 36. Two push columns 41 are located within the first groove 36 on opposite sides of each sliding column 38, with the two push columns 41 facing each other vertically. An H-shaped driving plate 42 is horizontally placed within the first groove 36. The bottom ends of both sliding columns 38 pass between the opposite sides of the driving plate 42. Two push pins 41 on opposite sides of the sliding pin 38 are located above and below the driving plate 42, respectively. The push pin 41 above the driving plate 42 is in contact with the driving plate 42, while the push pin 41 below the driving plate 42 has a gap with the driving plate 42. Two pressure plates 40 are the first clamping plates, and the side groove 39 is the second clamping plate. A threaded groove 43 is opened at the top of the driving plate 42, and a threaded post 44 is threadedly connected in the threaded groove 43. A vertical post 45 is vertically provided at the top of the threaded post 44. The side of the first plate 2 opposite to the fixed plate 1 has a [missing information - likely related to a specific type of plate]. The first groove 36 is connected to the rotating groove 46. A rotating roller 47 is rotatably connected inside the rotating groove 46. An eccentric wheel 48 is provided on the rotating roller 47, which is located inside the first groove 36. An annular sliding groove 49 is coaxially provided on the eccentric wheel 48. The top of the vertical column 45 extends vertically from the opening of the sliding groove 49 into the sliding groove 49 and contacts the bottom of the sliding groove 49. A turntable 57 is rotatably connected to the bottom of the threaded column 44. A compression spring 50 is provided between the turntable 57 and the bottom wall of the first groove 36. A rotating component for driving the rotating roller 47 to rotate is provided on the first plate 2.

[0044] like Figure 5 and Figure 6 and Figure 7 and Figure 8 and Figure 9When it is necessary to adjust the distance between the first clamping plate and the second clamping plate to clamp the steel pipe, simply drive the rotating roller 47 to rotate via the rotating component. At this time, the rotating roller 47 drives the eccentric wheel 48 to rotate. The eccentric wheel 48 pushes the vertical column 45, the threaded column 44, and the driving plate 42 to move away from the second groove 37 through the sliding groove 49. At this time, the threaded column 44 and the driving plate 42 move downward, the compression spring 50 is compressed, and the two sliding columns 38 and the pressure plate 40 follow the driving plate 42 to move downward. At this time, the pressure plate 40 on the two sliding columns 38 approaches the steel pipe until the two... After one side of the inclined surface of the pressure plate 40 on the sliding column 38 contacts the outer wall of the steel pipe, the driving plate 42 continues to move away from the second groove 37. At this time, the push column 41 on the two sliding columns 38 located above the driving plate 42 separates from the driving plate 42. The driving plate 42 gradually approaches the push column 41 on the two sliding columns 38 located below the driving plate 42. When the driving plate 42 and the push column 41 on the two sliding columns 38 located below the driving plate 42 are pressed together, the bottom end of the outer wall of the steel pipe can be pressed into the side groove 39. At this time, the clamping of the steel pipe can be completed. It is simple and convenient to use.

[0045] like Figure 8 The two pressure plates 40 have a rubber anti-slip layer 56 on the inclined surface near the steel pipe, which abuts against the outer wall of the steel pipe. The purpose of this setting is to increase the frictional resistance between the pressure plate 40 and the steel pipe through the rubber anti-slip layer 56, so as to facilitate the clamping and positioning of the steel pipe and make it simple and convenient to use.

[0046] like Figure 6 and Figure 7 The rotating component includes a drive shaft 51 coaxially mounted on the rotating roller 47. The drive shaft 51 is located outside the first groove 36. A gear 52 is coaxially mounted on one end of the drive shaft 51 away from the rotating roller 47. A second plate 53 located above the gear 52 is horizontally slidably connected to the side of the first plate 2 away from the fixed plate 1. A second rack 54 that meshes with the gear 52 is provided at the bottom end of the second plate 53 along the length direction of the second plate 53. A second cylinder 55 is provided on the first plate 2 to push the second plate 53 to move horizontally. The purpose of this arrangement is that when it is necessary to drive the rotating roller 47 to rotate, it is only necessary to open the second cylinder 55. At this time, the piston rod of the second cylinder 55 pushes the second plate 53 to drive the second rack 54 to move horizontally. At this time, the rotating roller 47 can be driven to rotate through the cooperation of the second rack 54 and the gear 52. It is simple and convenient to use.
