TECHNICAL FIELD

[0002] Linear guide rails are widely used in occasions requiring high precision or high-speed linear reciprocating motion, and can bear a certain torque to perform precise reciprocating linear motion in a given direction. In the production process of linear guide rails, drilling is a key step for providing necessary hole positions for subsequent installation. Usually, this process is completed by relying on specially designed drilling equipment.

[0003] After searching, a patent with authorization announcement number CN117773190B discloses an intelligent adjustment hole distance type drilling equipment for linear guide rail production, which comprises a bottom plate, two side plates installed on the bottom plate, a module and a tool plate installed above the bottom plate, the tool plate being installed on the module, a top plate installed above the two side plates, supports installed on both sides of the tool plate above the bottom plate, a machine box installed on the supports, a drill bit installed on the machine box, drilling cylinders installed at both ends of the machine box, the machine box being driven to move up and down by the drilling cylinders, the machine box driving the drill bit to rotate, the distance between the two connected sleeve shells being adjusted by the electric telescopic rod, the distance between the two adjacent drill bits being adjusted to meet the requirement of machining different hole distances on the same linear guide rail.

[0031] Referring toFigure 5 and Figure 6 As shown in the drawings, the infrared sensor one 9 is installed on the middle of the inner wall of the support frame 6 near the feeding side, the position of the infrared sensor one 9 corresponds to the drilling position of the straight hole drilling machine 75, the side of the support frame 6 away from the infrared sensor one 9 is provided with a corresponding receiver one 91, the receiver one 91 is built-in with a controller for switching the electric roller 22 on the feeding side, the infrared sensor two 92 is installed on the middle of the inner wall of the support frame 6 near the discharging side, the side of the support frame 6 away from the infrared sensor two 92 is provided with a corresponding receiver two 93, the receiver two 93 is built-in with a controller for switching the electric roller 22 on the discharging side, the receiver one 91 receives the detection infrared light emitted by the infrared sensor one 9 in real time, when the guide rail workpiece 01 is conveyed to the target drilling position by the electric roller 22 on the feeding side, the guide rail workpiece 01 will block the signal transmission between the infrared sensor one 9 and the receiver one 91, at this time the receiver one 91 can control the electric roller 22 on the feeding side to pause the transmission of the guide rail workpiece 01, until the guide rail workpiece 01 completes the drilling, then continue to transmit the next one, improve the automation degree of the drilling device.

[0032] When the linear guide workpiece 01 is drilled by the drilling device, the electric roller 22 on the feeding side of the material support 2 is started, and then the linear guide workpiece 01 to be processed is placed on the feeding side of the material support 2. Then the electric roller 22 drives the linear guide workpiece 01 to push along the material support 2 to the predetermined drilling position. At this time, the linear guide workpiece 01 transmitted to the drilling position will block the signal transmission between the infrared sensor 1 9 and the receiver 1 91. The receiver 1 91 will automatically control the electric roller 22 on the feeding side to stop, so that the transmitted linear guide workpiece 01 is stopped at the drilling position of the material support 2. Then the receiver 1 91 starts the driving part 5 to drive the two clamping mechanisms 3 on the material support 2 to move synchronously to the front and rear ends of the linear guide workpiece 01. At this time, according to the position of the first drilling on the linear guide workpiece 01, the servo motor 44 on the clamping mechanism 3 near the discharging side is started. The servo motor 44 drives the threaded rod 43 to rotate, and the threaded rod 43 drives the electric push rod 45 and the positioning plate 46 on the sliding plate 42 to slide along the guide frame 41, so that the positioning plate 46 is adjusted to the appropriate position. Then the positioning plate 46 driven by the electric push rod 45 extends into the mounting frame 31, so that the positioning plate 46 respectively abuts against the front end of the linear guide workpiece 01, realizing the preliminary positioning of the drilling linear guide workpiece 01. When the visual sensor 35 on the clamping mechanism 3 detects the end of the linear guide workpiece 01 to be clamped, the driving part 5 controls the clamping mechanism 3 to stop, and the visual sensor 35 controls the motor 1 34 of the clamping mechanism 3 to start. The motor 1 34 drives the bidirectional screw 33 to rotate, and the bidirectional screw 33 drives the two symmetrical clamping plates 32 to move synchronously towards each other, so as to firmly clamp the corresponding linear guide workpiece 01. At this time, the clamping mechanism 3 near the feeding side can clamp the adjacent ends of the two linear guide workpieces 01. After the linear guide workpieces 01 are clamped, the drilling mechanism 7 is driven by the hydraulic cylinder 8 to descend, so that the drill bits of the three drills in the drilling mechanism 7 approach the surface of the linear guide workpiece 01. Then the three drills in the drilling mechanism 7 work in sequence according to the preset program: the fixed-position straight-hole drill 75 drills a through hole first; then the sliding-mounted counterbore drill 76 processes a counterbore hole at the corresponding position;Finally, the chamfering machine 77, also slidingly installed, completes the chamfering process of the hole. During the drilling process, the driving member 5 is activated, the motor 2 55 drives the gear rail 21 through the worm 54, the worm wheel 53, and the gear meshing, intermittently moves the clamping mechanism 3 and the guide rail workpiece 01 clamped thereby, so that each drill bit can drill at different positions along the length of the guide rail workpiece 01. During the drilling process, when the tail end of the guide rail workpiece 01 clamped by the two clamping mechanisms 3 passes between the infrared sensor 1 9 and the receiver 1 91, the infrared sensor 1 9 and the receiver 1 91 resume signal transmission, and the receiver 1 91 can again control the electric roller 22 on the feeding side to start. At this time, the operator can place the next guide rail workpiece 01 to be drilled on the feeding side to prepare for drilling. Until the guide rail workpiece 01 is drilled, the two clamping mechanisms 3 will continue to synchronously drive the guide rail workpiece 01 to move to the discharging side. At this time, the signal transmission between the infrared sensor 2 92 and the receiver 2 93 interrupted by the guide rail workpiece 01 will be restored, the receiver 2 93 controls the two clamping mechanisms 3 to synchronously loosen the guide rail workpiece 01, and then the receiver 2 93 controls the electric roller 22 on the discharging side to start. The electric roller 22 on the discharging side will transport the drilled guide rail workpiece 01 out of the support rack 2, thereby completing the drilling of one guide rail workpiece 01. Then, the driving member 5 drives the two clamping mechanisms 3 to reset to the initial clamping position, and prepares to clamp the next guide rail workpiece 01 pushed in.

[0033] Referring to Figure 2 , Figure 8 and Figure 9 , the installation frame 71 is provided with a marking mechanism 10 near the side where the guide rail workpiece 01 is fed in. The marking mechanism 10 includes a fixed frame 101 fixedly connected to the bottom of the installation frame 71. A rack block 102 is slidingly connected to the fixed frame 101. A guide cylinder 103 is fixedly installed at the bottom of the rack block 102. A marking pen 104 is slidingly arranged at the bottom of the guide cylinder 103. The distance between the marking pen 104 and the drill bit of the straight hole drilling machine 75 is equal to the distance between the drill bits of the straight hole drilling machine 75 and the counterbore drilling machine 76. A spring 105 is arranged between the guide cylinder 103 and the marking pen 104. A gear wheel 2 106 is rotatably connected to the fixed frame 101. The gear wheel 2 106 is meshed with the rack block 102. A rack 107 is fixedly connected to one side of the housing of the counterbore drilling machine 76. The gear wheel 2 106 and the rack 107 are meshed with each other. The tooth pitch of the rack block 102 and the rack 107 is consistent. When the drilling mechanism 7 adjusts the drilling distance, the rack 107 moving with the counterbore drilling machine 76 will drive the meshed gear wheel 2 106 to rotate, so that the gear wheel 2 106 drives the rack block 102 and the marking pen 104 to move the same distance. When the drilling mechanism 7 moves downward to drill, the marking pen 104 can mark in advance after contacting the surface of the guide rail workpiece 01, thereby assisting the operator to determine whether the subsequent drilling mechanism 7 can accurately drill.

[0034] When the drilling mechanism 7 adjusts the drilling distance, the movement of the counterbore drill 76 will synchronously drive the rack frame 107 on its shell, the rack frame 107 drives the meshed gear two 106 to rotate, the gear two 106 drives the meshed rack block 102 on the other side and the guide cylinder 103 and the marker pen 104 fixed thereon to slide along the fixed frame 101, at this time, the movement distance of the guide cylinder 103 and the marker pen 104 is the same as that of the counterbore drill 76, which ensures that the distance between the marker pen 104 and the drill bit of the straight hole drill 75 is always equal to the adjusted distance between the drill bits of the straight hole drill 75 and the counterbore drill 76, and then, when the hydraulic cylinder 8 drives the entire drilling mechanism 7 to descend to prepare for drilling, the marker pen 104 will contact the guide rail workpiece 01 surface before the drill bit, and under the buffering action of the spring 105, the marker pen 104 clearly stamps or draws a mark on the workpiece, which directly indicates the position about to be drilled by the straight hole drill 75, and assists the operator to judge whether the drilling positioning is accurate or not in real time, and facilitates the operator to adjust the drilling distance of the drilling mechanism 7.

[0035] Referring to Figure 10 As shown in FIG. 11, the shells of the straight hole drill 75, the counterbore drill 76 and the chamfering drill 77 are fixedly installed with air cylinders 11 on one side, the telescopic rods of the air cylinders 11 are fixedly installed with annular frames 111, the annular frames 111 are arranged around the drill bits of the corresponding drills, the annular brushes 112 are rotatably installed on the inner side of the annular rings of the annular frames 111, the inner side of the annular brushes 112 is provided with bristles, the bristles on the inner side of the annular brushes 112 are notched on one side corresponding to the drill bits, the notched positions of the bristles on the inner side of the annular brushes 112 are opposite to the drill bits, the annular frames 111 are fixedly installed with motors four 113, the motors four 113 drive the annular brushes 112 through the belt pulley set two 114, the shells of the straight hole drill 75, the counterbore drill 76 and the chamfering drill 77 are assembled with nozzles 12 on the other side, the nozzles 12 are directed to the drill bits of the corresponding drills, and the nozzles 12 can spray cutting fluid to the drill bits of the drills for cooling and cleaning after being connected with a liquid pump, when the drilling mechanism 7 completes a round of drilling, the air cylinders 11 are enabled to drive the annular frames 111 to perform a reciprocating motion at the drill bits of the corresponding drills, and the motors four 113 are simultaneously driven to rotate the annular brushes 112, so that the drill bits of the corresponding drills can be cleaned in time, and the quality of subsequent drilling of the guide rail workpiece 01 is improved.

[0036] Referring to Figure 2 and Figure 11 As shown in FIG. 12, the top of the machine base 1 is provided with a collection frame 13 for collecting drilling debris, the top opening of the collection frame 13 is fixedly connected with inclined guide plates 14 symmetrically, the bottom of the guide plates 14 is provided with a filter screen 15, and the filter screen 15 is used to separate drilling debris and cutting fluid, so that the cutting fluid flows down through the filter screen 15, and the debris is intercepted on the surface of the filter screen 15.

[0037] When the drilling mechanism 7 completes a round of drilling on the guide rail workpiece 01, the drill bit on each drilling machine is lifted, the air cylinder 11 on each drilling machine is actuated, the air cylinder 11 pushes the annular frame 111 with the annular brush 112 installed on the inner side of the annular frame 111 to move along the drill bit axis for one reciprocating motion (usually from the drill bit root to the tip and back), while the motor four 113 drives the annular brush 112 to rotate at high speed through the belt pulley set two 114, the annular brush 112 is covered with bristles on the inner side, but there is a gap on the side facing the drill bit, which ensures that the annular brush 112 will not collide with the drill bit itself. The high-speed rotating bristles tightly wrap and sweep the grooves and edges of the drill bit, effectively removing adhered metal chips and oil stains. During the cleaning process, the nozzles 12 located on the other side of the drilling machine housing continuously spray cutting fluid from the external liquid pump to cool and lubricate the drill bit, and help flush away the debris stripped by the annular brush 112, together ensuring the cleanliness of the drill bit and the quality of subsequent drilling. The removed debris, splashed cutting fluid, and waste generated during drilling are guided by the inclined guide plate 14 to fall into the collection frame 13 below. When the mixture flows onto the filter screen 15, the liquid cutting fluid flows through the holes of the filter screen 15 into the bottom of the collection frame 13, so as to be recovered or drained for processing. The solid drilling debris is effectively intercepted by the filter screen 15 and accumulates on the surface of the filter screen 15, which is convenient for periodic centralized cleaning, realizing automatic separation and recovery of debris and cutting fluid.

Any equivalent changes made in accordance with the content described in the claims of the present application shall be included within the scope of the claims of the present application.
