[0002] Guide rail: A device with grooves or ridges made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion occasions. They have higher rated loads than linear bearings, and can bear a certain torque. They can achieve high-precision linear motion under high load conditions.

The top of the machine low plate is fixedly connected to the X-axis motion square rail, and an X-axis servo motor is arranged above the X-axis motion square rail. The top of the X-axis servo motor is installed with an X-axis rear guide rail protective cover, and the left side of the X-axis servo motor is fixedly connected to the X-axis ball screw. This linear guide rail automated processing equipment, by adopting a unique three-axis motion mode, better solves the problem that the long guide rail can only be drilled with a hand drill. When drilling and other processing, first, the product needs to be placed on the workpiece platform bracket, and then the drill bit inside the opposite spindle power head can be used for drilling processing, so as to complete the multi-functional processing operations such as drilling, tapping and milling of the guide rail. The overall structure is simple, with the characteristics of fast speed, high precision, time-saving and labor-saving, and strong practicality.

[0024] Beneficial effects of the present invention:

[0025] 1. The present invention designs a controller, a clamping mechanism, an automatic tool changing mechanism and a processing mechanism, and through the cooperation of the four, it is possible to mill longitudinal grooves, mill transverse grooves, drill mounting holes and chamfer the tops of the forming guide rails and the mounting holes on the metal block. Compared with the prior art, the present invention can realize the integrated processing of grooving, drilling and chamfering, which is more practical. At the same time, it can prevent fingers from being cut due to failure to chamfer when manually taking materials, thereby reducing safety hazards.

[0026] 2. The present invention designs an automatic tool changing mechanism, namely a clamping rod, a second milling cutter, a chamfering cutter, a drill bit, a lifting assembly and a rotating assembly. The clamping rod cooperates with the lifting assembly to realize the insertion and extraction of the first milling cutter or the second milling cutter, the chamfering cutter and the drill bit. The position of the first milling cutter, the second milling cutter, the chamfering cutter and the drill bit can be swapped through the rotating assembly, thereby realizing automatic replacement of each tool without the need for manual replacement of the tool, thereby greatly saving processing time and improving the processing efficiency of the guide rail.

[0027] 3. The present invention designs a first connecting shaft, a second connecting shaft, a first milling cutter, a slide groove, a slide rod, a tightening spring, a buckle, a slot and three mounting blocks. When replacing the tool, the buckle-type plug-in and pull-out structure can be used to realize the rapid plug-in and pull-out of the connecting shaft on each tool and the mounting plate or the mounting block, which saves time and improves the adjustment efficiency of the tool. At the same time, by designing a positioning block and a positioning groove, each tool can be accurately docked with the first connecting shaft or the second connecting shaft without causing installation deviation, thereby improving the accuracy and speed of installation and further improving the processing efficiency of the guide rail.

[0028] 4. The present invention designs a rotating component. On the one hand, when the first milling cutter mills a transverse groove, the second milling cutter can be rotated to a vertical state, and a longitudinal groove can be quickly milled on the metal block, thereby improving the grooving efficiency. On the other hand, the chamfering angle of the chamfering cutter can be adjusted to meet the chamfering requirements of different slopes, prevent the chamfer from being too large or protruding, avoid poor installation of the guide rail accuracy or interference with the slider, and help improve the processing quality of the guide rail.

[0029] 5. The present invention facilitates the rapid disassembly and assembly of each tool by designing a snap-on plug-in structure. When any tool is damaged, it is convenient to remove, replace and install it in time, thereby improving the maintenance efficiency of the machining center.

[0030] 6. The present invention designs an avoidance groove so that the drill bit will move closer to the top of the processing table when drilling a metal block. The avoidance groove plays a role in avoiding the drill bit to prevent the processing table from being damaged by drilling. At the same time, it has a certain collection effect on metal chips that fall during drilling to prevent them from accumulating in the drilled installation hole.

[0031] 7. The present invention designs an insert rod and an arc-shaped guide groove. During the rotation of the rotating plate, the insert rod is fixedly connected to the rotating plate and plugged into the arc-shaped guide groove, thereby ensuring that the rotating plate can rotate smoothly counterclockwise along the second slide plate, thereby improving the stability of the rotation and ensuring that each tool on the rotating plate can stably adjust the processing angle, thereby meeting different processing requirements and improving the flexibility of the machining center.

Then, the screw slide 615 drives the drill bit 53 to slide horizontally to the metal block. , and keep the drill bit 53 facing the longitudinal groove 8, and then drive the drill bit 53 to descend through the screw rod 612 and the first motor to open a plurality of mounting holes 9 in the transverse groove 7. When a plurality of mounting holes 9 are drilled, the drill bit 53 is first reset through the screw slide 615, and then the chamfering cutter 52 is driven to rotate to one end close to the clamping rod 50 through the gear ring 552, and then the drill bit 53 and the chamfering cutter 52 are driven to exchange positions through the second micromotor 541 and the clamping rod 50, and finally the top ends of the longitudinal groove 8, the top ends of the metal block and the tops of a plurality of mounting blocks 553 are chamfered through the position adjustment component 61, thereby realizing the processing of the entire guide rail.

[0072] Reference Figure 7As shown, both ends of the clamping rod 50 are provided with arc grooves 500 for inserting the first connecting shaft 601 and the second connecting shaft 555, and two accommodating grooves are symmetrically arranged at both ends of the inner wall of the clamping rod 50, and an arc-shaped pressure block 501 is inserted inside each accommodating groove. Two micro electric push rods 502 are symmetrically arranged on the inner wall of the clamping rod 50, and the output end of each micro electric push rod 502 is fixedly connected to an arc-shaped pressure block 501, and each micro electric push rod 502 is electrically connected to the controller 3. Each micro electric push rod 502 cooperates with an arc-shaped pressure block 501 to tighten the first connecting shaft 601 or the second connecting shaft 555 entering the arc groove 500, so as to facilitate the clamping rod 50 to cooperate with the lifting assembly 54 to pull the first connecting shaft 601 or the second connecting shaft 555 out of the mounting plate 600 or the mounting block 553.

[0073] Reference Fig. 9As shown, two positioning grooves are symmetrically arranged on the inner wall of the mounting plate 600, and two positioning plugs 603 are symmetrically arranged on the top outer wall of the first connecting shaft 601. Each positioning plug 603 is plugged into a positioning groove. An axial hole for inserting the first connecting shaft 601 is provided at the center of the mounting plate 600. Two slide grooves 604 are symmetrically arranged on the inner wall of the mounting plate 600. Each slide groove 604 is connected with the axial hole. A slide rod 605 is slidably arranged inside each slide groove 604. A tightening spring 606 is sleeved on the outer wall of each slide rod 605. A buckle 607 is fixedly arranged at one end of each slide rod 605 close to the axial hole. Two card grooves 608 are symmetrically arranged on the top outer wall of the first connecting shaft 601. Each buckle 608 is symmetrically arranged on the top outer wall of the first connecting shaft 601. 07 are all engaged with a slot 608, and each clip 607 and a slot 608 are triangular prism structures. The internal structures of the mounting plate 600 and the three mounting blocks 553 are the same, and the structures of the first connecting shaft 601 and the three second connecting shafts 555 are the same. When the first connecting shaft 601 is pulled vertically downward from the mounting plate 600, the clip 607 will force the slide bar 605 to slide to the end away from the shaft hole under the action of the vertical downward pulling force of the first connecting shaft 601, thereby driving the tightening spring 606 to contract, so that the clip 607 is disengaged from the slot 608, and the first connecting shaft 601 is pulled out of the mounting plate 600. When the first milling cutter 602 and the second milling cutter 51 are swapped, the second connecting shaft 555 rotates to When the second connecting shaft 555 is lifted up and aligned with the slot 608 and the buckle 607, the buckle 607 is no longer resisted by the outer wall of the second connecting shaft 555, so that the clamping spring 606 is reset to its initial state, and then the buckle 607 is driven by the slide bar 605 to snap into the inside of the slot 608, so that the second connecting shaft 555 and the installing plate 600 are connected, which is convenient for cutting the longitudinal groove 8. The internal structure is the same, and the structure of the first connecting shaft 601 and the three second connecting shafts 555 is the same, so the insertion and removal of the first connecting shaft 601 and the mounting block 553 are the same as the above steps. The positioning groove and the positioning plug 603 cooperate to enhance the rapid insertion of the first connecting shaft 601 or any second connecting shaft 555 and the mounting disk 600, and improve the speed and accuracy of its clamping. It should be noted that each time the mounting disk 600 stops rotating, the two positioning grooves on its inner wall must be kept in the same direction as the two positioning plugs 603 on the first connecting shaft 601 or the second connecting shaft 555. In this way, the first connecting shaft 601 or any second connecting shaft 555 can be quickly clamped with the mounting disk 600.

[0074] Reference Figure 6As shown, the clamping assembly 40 includes a cylinder 400, a push plate 401 and a clamping block 402. The cylinder 400 is fixedly arranged on the top of the processing table 2, the push plate 401 is fixedly arranged on its output end, the clamping block 402 is slidably arranged on the top of the processing table 2, and the end of the push plate 401 away from the cylinder 400 is fixedly connected to the clamping block 402. The cylinder 400 is electrically connected to the controller 3. When processing the guide rail, first, the strip metal block used to make the guide rail is horizontally placed between the three blocks 41, and then the cylinder 400 is started through the controller 3, so that its output end drives the clamping block 402 to slide toward the end close to the metal block through the push plate 401 to clamp the metal block, and cooperate with the three blocks 41 to achieve the clamping and fixation of the metal block.

[0075] Reference Figure 1 and Figure 5 As shown, an avoidance groove 20 for inserting a drill bit 53 is provided on the top of the processing table 2, and two protective doors 10 are symmetrically arranged on the outer wall of the shell 1. A glass observation window is provided on the outer wall of each protective door 10, and a handle is fixed on the outer wall of each protective door 10. When the metal block is fixed, the two protective doors 10 are closed, and the internal processing conditions can be observed through the glass observation window. When drilling a hole in the metal block, the drill bit 53 will approach the top of the processing table 2. The avoidance groove 20 plays a role in avoiding the drill bit 53 to prevent the processing table 2 from being damaged by drilling. At the same time, it has a certain collection effect on metal chips dropped during drilling.

[0076] The working principle of the present invention is as follows: when processing the guide rail, firstly, the strip metal block used to make the guide rail is placed horizontally between the three blocks 41, and then the cylinder 400 is started through the controller 3, so that its output end drives the clamping block 402 to slide toward one end close to the metal block through the push plate 401, so as to clamp the metal block, and cooperate with the three blocks 41 to achieve the clamping and fixing of the metal block.

[0077] After the metal block is fixed, the two protective doors 10 are closed and the internal processing conditions can be observed through the glass observation window. The drill bit 53 will approach the top of the processing table 2 when drilling the metal block. The avoidance groove 20 serves to avoid the drill bit 53 to prevent damage to the processing table 2. At the same time, it has a certain collection effect on metal chips dropped during drilling.

[0078] When the two protective doors 10 are closed, the first micromotor 613 is started through the controller 3, so that the screw 612 on its output end rotates. Since the screw 612 is threadedly connected to the lifting block 614, the screw slide 615 is fixedly connected to the lifting block 614, and the screw slide 615 is slidingly connected to the first slide plate 610 through two first slide rails, and then the lifting block 614 drives the screw slide 615 and the slider 617 thereon to descend. Due to the connection between the second slide plate 616 and the slider 617, the first milling cutter 602 is arranged on the second slide plate 616, and then the first milling cutter 602 is driven to descend vertically, and then the first motor 60 is started through the controller 3, so as to drive the first connecting shaft 601 and the first milling cutter 602 thereon to rotate, and then the first milling cutter 602 is driven to slide horizontally along the metal block through the screw slide 615 to mill a transverse groove 7 on the metal block.

[0079] After the transverse groove 7 is milled on the metal block, the first milling cutter 602 is reset by the screw slide 615, and then the second micromotor 541 is started by the controller 3, so that its output end drives the clamping rod 50 to rotate ninety degrees clockwise. When the first connecting shaft 601 and one of the second connecting shafts 555 close to the clamping rod 50 enter the two arc grooves 500 at both ends of the clamping rod 50, the two micro electric push rods 502 are started by the controller 3, so that the output ends of the two micro electric push rods 502 are extended, thereby driving the two arc-shaped pressing blocks 501 to extend from the accommodating grooves, and the first connecting shaft 601 and one of the second connecting shafts 555 close to the clamping rod 50 are pressed. Then the second electric push rod 540 is started by the controller 3. The push block 543 is fixedly connected to the lifting plate 542, and then the first connecting shaft 601 and the first milling cutter 602 thereon and the second milling cutter 51 on one of the second connecting shafts 555 close to the clamping rod 50 are respectively pulled out from the mounting disk 600 and one of the mounting blocks 553 through the clamping rod 50, and then the second micromotor 541 drives the clamping rod 50 to continue to rotate one hundred and eighty degrees clockwise to achieve the position exchange of the first milling cutter 602 and the second milling cutter 51, and then the second electric push rod 540 drives the clamping rod 50 to rise, and then drives the first connecting shaft 601 and the second connecting shaft 555 clamped at both ends thereof to be inserted into the interior of the mounting disk 600 and one of the mounting blocks 553 respectively, to achieve the fixed installation of the second milling cutter 51 on the mounting disk 600.

[0080] After the second milling cutter 51 is fixedly installed on the mounting plate 600, the second motor 620 is started by the controller 3, thereby driving the synchronous wheel 623 on its output end to rotate counterclockwise by 90 degrees. Since the other synchronous wheel 623 is fixedly connected to one end of the rotating shaft, the rotating plate 621 is fixedly connected to the end of the rotating shaft away from the synchronous wheel 623. The two synchronous wheels 623 are connected by the synchronous belt 622, thereby driving the rotating plate 621 and the first motor 60 and the second milling cutter 51 thereon to rotate counterclockwise by 90 degrees, that is, the second milling cutter 51 rotates to a vertical state, and then the first motor is started by the controller 3. 60, drives the second milling cutter 51 on its output end to rotate, and then drives the second slide plate 616, that is, the second milling cutter 51 installed thereon, to slide horizontally along the top of the metal block through the slider 617 on the screw slide 615 to achieve the cutting of the longitudinal groove 8 until the longitudinal groove 8 and the transverse groove 7 are connected, and then drives the second milling cutter 51 to reset through the screw slide 615. During the counterclockwise rotation of the rotating plate 621, since the plug rod 624 is fixedly connected to the rotating plate 621, the plug rod 624 is plugged into the arc guide groove, thereby ensuring that the rotating plate 621 can rotate smoothly counterclockwise along the second slide plate 616, thereby improving the stability of the rotation.

[0081] After the second milling cutter 51 is reset, the servo motor 550 is started through the controller 3, so that its output end drives the gear 551 to rotate counterclockwise. Since the ring gear 552 is rotatably connected with the annular slide rail 554, the gear 551 is meshed with the ring gear 552, and the tops of the three mounting blocks 553 are fixedly connected with the bottom of the ring gear 552. The second milling cutter 51, the chamfering cutter 52 and the drill bit 53 are respectively connected to the inner walls of the three mounting blocks 553 through the three second connecting shafts 555, thereby driving the ring gear 552 to rotate 120 degrees clockwise to achieve the exchange of the position of the drill bit 53 and the first milling cutter 602. Then, the second milling cutter 51 is pulled out from the mounting plate 600 through the clamping rod 50 in cooperation with the second electric push rod 540, and the drill bit 53 is pulled out from the second connecting shaft 555 connected thereto, and then the drill bit 53 is driven to exchange the position of the second milling cutter 51 through the second micromotor 541. 40 drives the lifting plate 542 and the clamping rod 50 to rise, driving the swapped drill bit 53 to engage with the mounting plate 600, and the second milling cutter 51 is engaged with one of the mounting blocks 553, and then the drill bit 53 is driven to slide horizontally to the top of the metal block through the screw slide 615, and the drill bit 53 is kept facing the longitudinal groove 8, and then the drill bit 53 is driven to descend through the screw 612 and the first motor to open a plurality of mounting holes 9 in the transverse groove 7. When a plurality of mounting holes 9 are drilled, the drill bit 53 is first reset through the screw slide 615, and then the chamfering cutter 52 is driven to rotate to one end close to the clamping rod 50 through the gear ring 552, and then the drill bit 53 and the chamfering cutter 52 are driven to exchange positions through the second micromotor 541 and the clamping rod 50, and finally the top ends of the longitudinal groove 8, the top ends of the metal block and the tops of a plurality of mounting blocks 553 are chamfered through the position adjustment component 61, thereby realizing the processing of the entire guide rail.

[0082] When the first connecting shaft 601 is pulled vertically downward from the mounting plate 600, the buckle 607 forces the slide bar 605 to slide toward the end away from the shaft hole under the action of the vertical downward pulling force of the first connecting shaft 601, thereby driving the pressing spring 606 to contract, so that the buckle 607 is disengaged from the clamping groove 608, and the first connecting shaft 601 is pulled out of the mounting plate 600. When the first milling cutter 602 and the second milling cutter 51 are swapped, the second connecting shaft 555 is rotated to the mounting plate 600. 00, when it is vertically inserted into the interior of the mounting plate 600, the buckle 607 will slide toward the end away from the shaft hole under the resistance of the top end of the second connecting shaft 555, thereby driving the slide bar 605 to slide toward the end away from the shaft hole and driving the tightening spring 606 to contract. When the second connecting shaft 555 rises to the point where the slot 608 is aligned with the buckle 607, the buckle 607 is no longer resisted by the outer wall of the second connecting shaft 555, so that the tightening spring 606 is reset to its initial position. The first and second connecting shafts 555 are in the same structure as the mounting plate 600, and the first and second connecting shafts 555 are in the same structure as the mounting plate 600.
