They are used to support and guide moving components to perform reciprocating uniform linear motion in a given direction. According to the friction characteristics, linear motion guide rails can be divided into types such as rolling friction guide rails, rolling friction force guide rails, elastic friction guide rails, and liquid friction guide rails; There are still some problems in the existing technology when drilling and processing linear guides: When the existing technology drills and processes linear guides, it is inconvenient to automatically limit the position of the linear guide during the processing, resulting in poor stability of the linear guide during the drilling process, and further affecting the drilling effect of the linear guide. After the drilling of the linear guide is completed, there are certain burrs inside the drilled hole and on the upper and lower surfaces of the hole.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment: As Figure 1-12As shown in the figure, the present invention provides a drilling device for the production and processing of linear guides, including a conveying frame 1. Uniformly distributed conveying rollers 2 are rotatably installed on the inner wall of the conveying frame 1. A collection box 21 is fixedly installed in the middle of the conveying frame 1. A drilling platform 22 is fixedly installed on the upper surface of the collection box 21. An insertion groove 23 is formed on the surface of the drilling platform 22, and the insertion groove 23 communicates with the inner cavity of the collection box 21. A U-shaped frame 24 is also fixedly installed in the middle of the conveying frame 1. A first frame plate 25 and a second frame plate 26 are respectively fixedly installed on the inner walls of the U-shaped frame 24. A drilling mechanism 3 is arranged on one side of the first frame plate 25, and a grinding mechanism 5 is arranged on one side of the second frame plate 26. A driving mechanism 8 for the drilling mechanism 3 and the grinding mechanism 5 is arranged on one side of the U-shaped frame 24. A limiting mechanism 10 is arranged on the upper surface of the drilling platform 22.

[0030] By adopting the above technical solutions, when the conveying rollers 2 start to convey the linear guide for drilling processing, as the linear guide moves, the linear guide is conveyed to the upper surface of the drilling platform 22. By setting the driving mechanism 8, the drilling mechanism 3 and the grinding mechanism 5, the driving mechanism 8 enables the drilling mechanism 3 to operate, and the drilling mechanism 3 drills the linear guide. After one drilling process is completed, the grinding mechanism 5 grinds and deburrs the hole wall and the upper and lower surfaces (the surfaces near the hole wall) of the linear guide. By setting the limiting mechanism 10, the drilling mechanism 3 and the grinding mechanism 5 limit the linear guide on the drilling platform 22 during the drilling process and the grinding and deburring process, thereby improving the stability of the linear guide during the processing. By setting the collection box 21, the debris generated during the drilling process and the grinding and deburring process falls into the collection box 21.

[0031] The drilling mechanism 3 includes a drilling machine 31. A first telescopic rod 32 is fixedly installed on the side of the U-shaped frame 24 away from the conveying frame 1. The piston end of the first telescopic rod 32 is fixedly connected to one end of the drilling machine 31. A U-shaped lifting seat 33 is slidably arranged on one side of the first frame plate 25. A first lower pressing plate 34 is fixedly installed on the side of the U-shaped lifting seat 33 away from the first frame plate 25. The piston end of the first telescopic rod 32 penetrates through the first lower pressing plate 34 and is fixedly connected to one end of the first lower pressing plate 34. Two guide rods 35 are fixedly installed on one side of the first frame plate 25, and the U-shaped lifting seat 33 is slidably connected to the two guide rods 35.

[0032] By adopting the above technical solution, by arranging the guide rod 35, the guide rod 35 guides the U-shaped lifting seat 33 in the vertical direction, so that the U-shaped lifting seat 33 keeps lifting in the vertical direction. By driving the U-shaped lifting seat 33 to lift vertically, the U-shaped lifting seat 33 makes the drill 31 lift synchronously through the first lower pressing plate 34. At the same time, the first lower pressing plate 34 pulls the piston end of the first telescopic rod 32, and the piston end of the first telescopic rod 32 follows to extend or contract, improving the stability of the drill 31. When the drill bit of the drill 31 contacts the linear guide rail on the drilling platform 22, with the descent of the drill 31, the single drilling process of the linear guide rail is completed.

[0033] Two first rotating rods 36 are rotatably installed on one side of the first frame plate 25. Transmission wheels 37 are fixedly installed at one ends of the two first rotating rods 36. A transmission belt 38 is drivingly connected between the two transmission wheels 37. An L-shaped synchronous rod 39 is fixedly installed on the outer wall of the transmission belt 38. A strip-shaped groove 4 is formed in the inner wall of the U-shaped lifting seat 33. One end of the L-shaped synchronous rod 39 away from the transmission belt 38 is in movable contact with one end of the strip-shaped groove 4.

[0034] By adopting the above technical solution, by driving the first rotating rod 36 to rotate, the first rotating rod 36 makes the transmission belt 38 transmit through the transmission wheel 37, and the transmission belt 38 makes the U-shaped lifting seat 33 lift vertically through the L-shaped synchronous rod 39 and the strip-shaped groove 4.

[0035] The grinding mechanism 5 includes two grinding discs 51 and two grinding wheels 52. One of the grinding discs 51 is fixedly connected with one of the grinding wheels 52.

Movable rods 54 are slidably installed in the inner walls of the two hollow rods 53. One end of the movable rod 54 is fixedly connected with the side of the grinding disc 51 away from the grinding wheel 52. Two second lower pressing plates 57 are arranged between the U-shaped frame 24 and the collection box 21. One end of the movable rod 54 close to the grinding disc 51 penetrates through the second lower pressing plate 57 and is rotatably connected with one end of the second lower pressing plate 57. Two second rotating rods 61 are rotatably installed on one side of the second frame plate 26. Rotating discs 62 are fixedly installed at one ends of the two second rotating rods 61.

[0036] By adopting the above technical solution, two grinding discs 51 and two grinding wheels 52 are arranged. When the two grinding discs 51 and the two grinding wheels 52 are close to each other in the vertical direction, the two grinding discs 51 grind and remove burrs on the upper and lower surfaces of the linear guide rail (the grinding disc 51 at the lower end rises vertically from the collection box 21, passes through the through slot 23 and contacts the lower surface of the linear guide rail), and the two grinding wheels 52 enter the hole formed by the drilling process to grind and remove burrs on the hole wall. By driving the second rotating rod 61 to rotate, the second rotating rod 61 is rotated. The driving rod 63 rotates with the axis of the rotating disk 62 as the center through the rotating disk 62, and the driving rod 63 makes the second lower pressure plate 57 rise and fall vertically through the first connecting seat 64, the pushing rod 66 and the second connecting seat 65. The second lower pressure plate 57 pulls the movable rod 54 to rise and fall vertically, and the movable rod 54 makes the grinding disk 51 and the grinding wheel 52 rise and fall synchronously. By setting two rotating disks 62 and two mirror-set pushing rods 66, when the two rotating disks 62 rotate synchronously in the same direction, the two second lower pressure plates 57 approach each other or move away from each other synchronously.

[0037] The outer walls of the two hollow rods 53 are each provided with two card slots 55, and the inner walls of the card slots 55 are slidably connected with card blocks 56.

[0038] By adopting the above technical solution, by setting the slot 55 and the block 56, when the movable rod 54 follows the second lower pressure plate 57 to rise and fall vertically, the movable rod 54 causes the block 56 to slide in the vertical direction along the inner wall of the slot 55, and when the hollow rod 53 rotates, the hollow rod 53 causes the movable rod 54 to rotate synchronously through the block 56, and by setting the guide slot 58, the guide block 59 and the L-shaped connecting plate 6, the guide block 59 guides the second lower pressure plate 57 in the vertical direction through the L-shaped connecting plate 6, so that the second lower pressure plate 57 keeps rising and falling in the vertical direction.

[0040] By adopting the above technical solution, the transmission shaft 67 is driven to rotate, and the transmission shaft 67 rotates the second rotating rod 61 through the first bevel gear 7 and the second bevel gear 71.

A roller 1083 is rotatably installed at one end of each of the two push plates 1080 away from the third connecting seat 1082. Fitting grooves 1090 are formed in the lower surfaces of the first lower pressing plate 34 and one of the second lower pressing plates 57. The roller 1083 is vertically corresponding to the fitting groove 1090.

[0044] By adopting the above technical solution, by setting the baffle plate 1010 and the limit plate 1020, after the linear guide rail is conveyed to the upper surface of the drilling platform 22, the linear guide rail enters between the baffle plate 1010 and the limit plate 1020 and contacts one side of the baffle plate 1010. When the drilling machine 31, the grinding disc 51 and the grinding wheel 52 perform drilling and deburring processing on the linear guide rail, the limit plate 1020 moves horizontally toward the side of the baffle plate 1010 and contacts the side of the linear guide rail to limit the linear guide rail, improving the stability of the linear guide rail during the drilling process and the deburring process. When the first lower pressing plate 34 descends vertically, the fitting groove 1090 on the lower surface of the first lower pressing plate 34 contacts a roller 1083, pushing the upper end of the push plate 1080. The angles at both ends of the push plate 1080 change, and the torsion spring in the third connecting seat 1082 deforms and stores energy. The push plate 1080 makes the limit plate 1020 move horizontally toward the side of the baffle plate 1010 through the third connecting seat 1082. When the second lower pressing plate 57 descends vertically, the fitting groove 1090 on the lower surface of the second lower pressing plate 57 contacts another roller 1083, pushing the upper end of the push plate 1080. The angles at both ends of the push plate 1080 change, and the torsion spring in the third connecting seat 1082 deforms and stores energy. The push plate 1080 makes the limit plate 1020 move horizontally toward the side of the baffle plate 1010 through the third connecting seat 1082. After the fitting groove 1090 is separated from the roller 1083, the torsion spring in the third connecting seat 1082 resets and drives the bottom end of the push plate 1080 to rotate in the reverse direction to the initial state, keeping the push plate 1080 at the initial angle, so as to facilitate pushing the push plate 1080 again later. By arranging a limit convex rod in the third connecting seat 1082, when the push plate 1080 is reset to the initial angle under the reverse acting force of the torsion spring, the limit convex rod limits the angle of the push plate 1080 to keep the push plate 1080 at the initial angle.

[0045] Chutes 1030 are provided on both sides of the drilling platform 22. The inner walls of the two chutes 1030 are both slidably connected with sliders 1040. One side of each of the two sliders 1040 is fixedly installed with a U-shaped connecting rod 1050. One end of each of the two U-shaped connecting rods 1050 is fixedly connected to the limit plate 1020. The inner walls of the two chutes 1030 are both fixedly installed with second telescopic rods 1060. The piston ends of the second telescopic rods 1060 are fixedly connected to one side of the sliders 1040. The outer walls of the two second telescopic rods 1060 are both movably sleeved with telescopic springs 1070. One end of each telescopic spring 1070 is fixedly connected to one end of the chute 1030, and the other end of the telescopic spring 1070 is fixedly connected to one side of the slider 1040.

[0046] By adopting the above technical solution, by setting the chute 1030, slider 1040, U-shaped connecting rod 1050, second telescopic rod 1060 and telescopic spring 1070, when the limiting plate 1020 moves horizontally, the slider 1040 makes the limiting plate 1020 move horizontally in the horizontal direction through the U-shaped connecting rod 1050. At the same time, the slider 1040 squeezes the second telescopic rod 1060 and the telescopic spring 1070. When the pushing plate 1080 stops being pushed to move horizontally towards the side of the material retaining plate 1010, the second telescopic rod 1060 and the telescopic spring 1070 make the slider 1040 slide in the reverse direction, and the slider 1040 makes the limiting plate 1020 and the pushing plate 1080 move in the reverse direction to the initial position through the U-shaped connecting rod 1050.

[0047] The present invention also provides a drilling method for a drilling device used in the production and processing of linear guides, including the following steps: S1. Drilling of the linear guide The linear guide to be processed is conveyed by the conveying roller 2, and the linear guide is conveyed to the upper surface of the drilling platform 22 and contacts one side of the material retaining plate 1010. By driving the first lower pressing plate 34 to descend and ascend vertically, the first lower pressing plate 34 makes the drilling machine 31 descend and ascend vertically. The drill bit of the drilling machine 31 contacts the linear guide during the descending process, and disengages from the linear guide after completing the drilling process of the linear guide; S2. Grinding and deburring inside the hole The linear guide on the drilling platform 22 is conveyed by the conveying roller 2 to make the hole on the linear guide vertically correspond to the grinding wheel 52. By driving the two second lower pressing plates 57 to approach and separate from each other, and synchronously driving the two grinding discs 51 and the two grinding wheels 52 to rotate, the two second lower pressing plates 57 make the two grinding discs 51 and the two grinding wheels 52 approach and separate from each other through the two movable rods 54. During the process of approaching each other, the two grinding discs 51 and the two grinding wheels 52 perform grinding and deburring processing on the hole wall and the upper and lower surfaces of the linear guide in the rotating state; S3. Limiting of the linear guide During the drilling process and the grinding and deburring process, by pushing the upper end of the pushing plate 1080 downward, the pushing plate 1080 makes the limiting plate 1020 move towards the side of the material retaining plate 1010 through the third connecting seat 1082. With the cooperation of the material retaining plate 1010, the limiting plate 1020 limits the linear guide.

[0048] Working principle: When the conveying roller 2 starts to convey the linear guide to be processed, as the linear guide is conveyed, the linear guide is conveyed to the upper surface of the drilling platform 22 (the length of the linear guide is greater than the length of the drilling platform 22), and one side of the linear guide contacts one side of the material retaining plate 1010. Subsequently, the conveying roller 2 is stopped from rotating, and the linear guide is stationary; Subsequently, the staff simultaneously activates the servo motor 86 and the drill 31. The drill bit of the drill 31 starts to rotate. At the same time, the drive shaft of the servo motor 86 causes the sector gear 88 to rotate through the rotating shaft 87. The sector gear 88 drives the first gear 85 to rotate. The first gear 85 causes the first transmission rod 81 to rotate. The first transmission rod 81 causes a corresponding first rotating rod 36 to rotate through two second synchronous pulleys 83 and the second synchronous belt 84. At this time, the two first rotating rods 36 cause the transmission belt 38 to transmit through two transmission wheels 37. The transmission belt 38 causes the U-shaped lifting seat 33 to descend and ascend vertically through the L-shaped synchronous rod 39 and the strip groove 4. The U-shaped lifting seat 33 causes the drill 31 to descend and ascend vertically through the first lower pressing plate 34. As the drill 31 descends, the drill bit of the drill 31 contacts the upper surface of the linear guide rail. After the single drilling process of the linear guide rail is completed, the U-shaped lifting seat 33 ascends vertically and causes the drill 31 to disengage from the linear guide rail through the first lower pressing plate 34, thus conveniently realizing the automatic drilling process of the linear guide rail, and effectively improving the convenience of the drilling process of the linear guide rail; During the ascending process of the drill 31, after the drill bit of the drill 31 disengages from the linear guide rail, the conveying roller 2 starts to operate. The conveying roller 2 continues to convey the linear guide rail, and the linear guide rail horizontally displaces on the drilling platform 22. When the hole formed by the drilling process is vertically aligned with the grinding wheel 52, the conveying roller 2 stops rotating, and the linear guide rail on the drilling platform 22 stops displacing; Meanwhile, after the U-shaped lifting seat 33 rises to the initial position, the sector gear 88 disengages from the first gear 85, meshes with the second gear 91 and drives the second gear 91 to rotate. The second gear 91 rotates the second transmission rod 9. The second transmission rod 9 rotates the transmission shaft 67 through the third bevel gear 92. The transmission shaft 67 rotates the two hollow rods 53 through four first synchronous pulleys 68 and two first synchronous belts 69. The two hollow rods 53 rotate the two grinding discs 51 and the two grinding wheels 52 through two movable rods 54. At the same time, the transmission shaft 67 rotates the two second rotating rods 61 synchronously and in the same direction through two first bevel gears 7 and two second bevel gears 71. The two second rotating rods 61 rotate the two rotating discs 62 synchronously and in the same direction. The two rotating discs 62 make the two driving rods 63 revolve around the axis of the corresponding rotating disc 62 as the center. The two driving rods 63 make the two second lower pressing plates 57 approach each other through two first connecting seats 64, two pushing rods 66 and two second connecting seats 65. The two second lower pressing plates 57 pull the two movable rods 54 and make the two grinding discs 51 and the two grinding wheels 52 approach each other through the two movable rods 54. At this time, first, the two grinding wheels 52 enter the holes formed by the drilling process. The two grinding wheels 52 grind and deburr the hole walls while approaching and rotating. Then, when the two grinding discs 51 contact the upper and lower surfaces of the linear guide rail, the upper and lower surfaces of the linear guide rail are ground and deburred (the surfaces near the holes). It should be noted that when the sector gear 88 meshes with the second gear 91 for one cycle, the two second lower pressing plates 57 approach and separate from each other for one cycle. After the grinding and deburring process is completed, the two grinding discs 51 and the two grinding wheels 52 disengage from the linear guide rail, thus conveniently realizing the grinding and deburring process of the holes inside, effectively improving the drilling effect of the linear guide rail, and at the same time effectively improving the efficiency of the drilling process of the linear guide rail; Meanwhile, during the process of the drilling rig 31 drilling the linear guide rail and the grinding discs 51 and the grinding wheels 52 grinding and deburring the linear guide rail, when the first lower pressing plate 34 or one of the upper second lower pressing plates 57 descends vertically, the fitting groove 1090 on the lower surface of the first lower pressing plate 34 or the second lower pressing plate 57 contacts the corresponding roller 1083. The upper ends of the two pushing plates 1080 are pushed downward through the corresponding roller 1083. The two pushing plates 1080 make the limiting plate 1020 move horizontally toward the side of the baffle plate 1010 through two third connecting seats 1082. The limiting plate 1020 contacts one side of the linear guide rail and, in cooperation with the baffle plate 1010, limits the linear guide rail during the drilling process and the grinding and deburring process, thus conveniently realizing the limitation of the linear guide rail during the drilling process and the deburring process, effectively improving the stability of the linear guide rail during the processing, and improving the drilling effect and the grinding and deburring effect of the linear guide rail.
