Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling device for linear guide rail processing and its usage method. Background Technology

[0002] As a core guiding component in precision mechanical transmission systems, the machining accuracy of linear guides directly affects the smoothness of the entire equipment's movement, positioning accuracy, and service life. During the manufacturing process of linear guides, it is typically necessary to drill mounting holes, lubrication holes, or weight-reducing holes in their main structure.

[0003] Currently, the following shortcomings exist in processing practices in this field: 1. Traditional clamping methods are incompatible with the guide rail structure, easily leading to clamping failure or workpiece damage: Most linear guide rails have recessed structures (such as grooves or raceways) on their sides for mounting sliders or sensors, and their cross-sectional shape is not a simple rectangle. Existing general-purpose clamps (such as flat-jaw vises and pressure plates) are difficult to effectively and without damage clamp such irregular cross-sections. Forced clamping can easily cause deformation of the guide rail side, surface scratches, or workpiece displacement during processing due to small contact area and uneven force, seriously impairing machining accuracy and product yield.

[0004] 2. Outdated drilling depth control methods: Currently, drilling depth mostly relies on operators manually controlling the machine tool feed or using rigid stops at a fixed height. The former has large accuracy fluctuations and is highly dependent on the operator's experience, while the latter is cumbersome to adjust, lacks flexibility, and is prone to vibration due to rigid collision at the moment of drill bit penetration, resulting in increased burrs at the hole opening and drill bit chipping, which cannot meet the mass production requirements of high consistency and high quality holes.

[0005] 3. Discrete processes and lack of automation: From workpiece handling, clamping and positioning, drilling to cooling and chip removal, and finished product unloading, each step is often independent and relies on manual intervention. This discrete operation mode leads to slow production cycle, high labor intensity, and harsh production environment (coolant splashing, chip accumulation), making it difficult to form a stable and efficient continuous production process.

[0006] Therefore, a drilling device for linear guide machining is needed to improve the above problems. Summary of the Invention

[0007] To address the problems of difficulty in clamping irregularly shaped sections of linear guides, inaccurate control of drilling depth, and low degree of automation in the process, this invention provides a drilling device for linear guide processing to solve the aforementioned problems.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A drilling device for machining linear guides includes a bidirectional sliding module, a linkage clamping assembly, a support assembly, a limiting assembly, a drilling rig, a carrier box assembly, a conveying assembly, and two fixing assemblies. The bidirectional sliding module includes a clamping linear module and a mounting plate fixed to the two sliding ends of the clamping linear module.

[0009] The two fixing components are respectively disposed on opposite sides of the two mounting plates. Each fixing component includes a fixing plate, a first bolt, and a sliding plate. The fixing plate is connected to the mounting plate by the first bolt, and the sliding plate is fixed to the top of the fixing plate and has a sliding groove on its side.

[0010] The linkage clamping assembly is provided for each fixed assembly. The linkage clamping assembly includes two sliders, two fixed blocks, a pin shaft, and two intersecting scissor plates. The two sliders slide in cooperation with the slide grooves on the slide plate. The two fixed blocks are fixed to the outer sides of the two sliders respectively. Each fixed block has a pin hole. The pin shaft passes through the pin holes of the two fixed blocks. Each scissor plate has a through hole and a connecting hole at both ends. The two scissor plates are hinged to a nut by a long bolt passing through the connecting hole at their center. The through hole at one end of each scissor plate is connected to the pin hole on a fixed block by a pin shaft. The other end of the scissor plate is fixedly connected to a clamping block.

[0011] The support assembly includes a support plate, a second bolt, a lead screw linear module, and a hydraulic push rod. The support plate is fixed to the top of the fixed plate by the second bolt. The fixed end of the lead screw linear module is installed on the top of the support plate, and the fixed end of the hydraulic push rod is installed on the sliding end of the lead screw linear module.

[0012] The limiting assembly includes a connecting plate, a connecting rod, a third bolt, a pad, and a spring. The connecting plate is fixed to the output end of the hydraulic push rod, with a through opening in the center and symmetrical insertion holes on both sides. The connecting rod is movably inserted into the insertion holes, with a threaded groove on its top and a pad fixed at its bottom. The third bolt is threaded into the threaded groove. The spring is movably sleeved on the outside of the connecting rod, with its upper end connected to the bottom surface of the connecting plate and its lower end connected to the top surface of the pad.

[0013] The drilling rig is installed on the top surface of the connecting plate, and its output shaft passes through the opening.

[0014] The carrier box assembly is located below the bidirectional sliding module. The carrier box assembly includes a carrier box, a drain valve, a support plate, and support legs. A slot is provided on the top of the carrier box. The drain valve is installed at the bottom of the carrier box. The support plate is fixed to the inner wall of the carrier box, and the support legs are fixed to the bottom of the carrier box. The conveying assembly includes two insert plates, a small belt conveyor, and a wedge block. The small belt conveyor is installed between the two insert plates, and the wedge block is fixed to the inner surface of the insert plates. The insert plates are inserted into slots at the top of the carrier box.

[0015] As a preferred embodiment of the present invention, the fixing component further includes a reinforcing plate, which is fixed between the fixing plate and the sliding plate.

[0016] By setting a reinforcing plate to be fixed between the fixed plate and the sliding plate, the overall structural strength and rigidity of the fixing component are significantly enhanced, effectively preventing deformation or shaking caused by force during clamping and drilling, thereby improving clamping stability and the service life of the device, and ensuring processing accuracy.

[0017] As a preferred embodiment of the present invention, the top of the carrier box is also provided with a threaded hole, and the bottom of the carrier box is recessed inward at the middle to form a clearance space for the bidirectional sliding module to pass through. The conveying assembly also includes a fourth bolt, which penetrates the top of the insert plate and is threadedly engaged with the threaded hole. The wedge block and the conveying edge of the insert plate are left with a gap, and the top of the fourth bolt is flush with the top surface of the insert plate.

[0018] The top of the carrier box has a threaded hole that mates with the fourth bolt, which facilitates the quick installation and fixing of the conveying components. The clearance space at the bottom provides sufficient running clearance for the bidirectional sliding module to avoid interference. There is a gap between the wedge block and the insert plate to facilitate the alignment and installation of the conveying components. The overall structure is reasonable and easy to assemble.

[0019] As a preferred embodiment of the present invention, a coolant nozzle is installed on the bottom end face of the connecting plate.

[0020] A coolant nozzle is installed on the bottom surface of the connecting plate, which can spray coolant onto the machining area during drilling, effectively reducing the temperature of the drill bit and the workpiece, reducing wear, and extending the service life of the drill bit. At the same time, the coolant can carry away chips, keep the machining area clean, and improve drilling quality and efficiency.

[0021] As a preferred embodiment of the present invention, the groove on the slide plate is a T-shaped groove, and the slider has a cross-sectional shape adapted to it.

[0022] The slide adopts a T-slot design, which is adapted to the cross-sectional shape of the slider, making it less likely for the slider to detach during sliding. This enhances the stability and accuracy of the guide, while also improving the load-bearing capacity, ensuring that the linkage clamping assembly moves smoothly and reliably with uniform clamping force.

[0023] In a preferred embodiment of the present invention, the diameter of the nut end of the third bolt and the diameter of the washer are both larger than the diameter of the insertion hole.

[0024] The nut end diameter of the third bolt and the diameter of the spacer block are both larger than the diameter of the jacking hole, preventing the connecting rod from slipping out of the jacking hole under the action of the spring, enhancing the structural safety of the limiting component, ensuring that the connecting rod and the spacer block are always in a controllable state during the drilling process, and improving the operation stability of the device.

[0025] As a preferred solution of the present invention, the fixing plate is in a "C" shape, its bottom is movably inserted into the recessed space at the bottom of the bearing box, and its top is located above the bearing box.

[0026] The fixing plate adopts a "C" shape structure and its bottom is movably inserted into the recessed space of the bearing box, which not only realizes the stable connection with the bearing box, but also provides additional support and limitation for the overall structure, enhancing the overall rigidity and vibration resistance of the device during the processing.

[0027] As a preferred solution of the present invention, a relief groove flush with the surface of the belt of the small belt conveyor is provided on the upper surface of the bearing plate.

[0028] A relief groove flush with the surface of the conveyor belt is provided on the upper surface of the bearing plate, enabling the linear guide rail to smoothly transition during the conveying process, avoiding jamming or deviation caused by the height difference, ensuring accurate workpiece positioning, and facilitating the smooth progress of subsequent clamping and drilling operations.

[0029] A method for using a drilling device for linear guide rail processing, the method comprising the following steps: First step, insert the insertion plate of the conveying component into the slot of the bearing box component and fix it with the fourth bolt, place the linear guide rail on the small belt conveyor, and convey it to the set position on the bearing plate.

[0030] Second step, start the bidirectional sliding module, drive the two mounting plates to move towards each other, and带动 the two fixing components and the linkage clamping component to move towards each other synchronously.

[0031] Third step, during the process of the slider sliding along the chute, through the transmission of the pin shaft and the scissors plate, make the two clamping blocks move towards each other and clamp both sides of the linear guide rail.

[0032] Fourth step, start the screw linear module of the support component,带动 the hydraulic push rod and the drill to horizontally move to the drilling station, and then start the hydraulic push rod to drive the drill and the limiting component to descend for drilling operations.

[0033] Fifth step, after drilling is completed, the hydraulic push rod resets and rises, the bidirectional sliding module reversely drives the linkage clamping component to release the linear guide rail, and the processed linear guide rail is removed through the conveying component.

[0034] Compared with the prior art, the present invention achieves bidirectional synchronous and adaptive clamping under a single power drive by setting up a linkage clamping mechanism composed of a bidirectional sliding module, a slider, a pin shaft and a cross scissor plate, and achieves the following outstanding beneficial effects: This non-destructive clamping mechanism with an adaptive cross-section offers superior clamping stability and workpiece protection. Utilizing an integrated design of a bidirectional sliding module, slider, T-slot guide, and cross-scissor plate transmission, it transforms a single horizontal driving force into precise opposing motion of two clamping blocks. It can adapt to irregularly shaped cross-sections of linear guideways with grooves and raceways, achieving stable centering clamping without the need for specialized fixtures. The clamping blocks can be paired with flexible pads to ensure even force transmission with the scissor plates, preventing workpiece surface scratches and lateral deformation while increasing the effective contact area. The static friction generated by left and right clamping, combined with the bottom support of the bearing plate, effectively counteracts the vertical impact force generated by the drill feed during drilling, indirectly constraining the guideway's vertical movement and preventing both lateral and vertical workpiece displacement during processing. This significantly improves processing accuracy and product yield. The reinforced structure of the "U"-shaped fixing plate and reinforcing plate further enhances the rigidity and vibration resistance of the clamping mechanism, adapting to the high-frequency clamping requirements of batch processing.

[0035] The composite limiting assembly, featuring spring buffer, adjustable pad, and threaded adjustment, utilizes a spring to provide constant preload, eliminating depth errors caused by mechanism clearances and preventing rigid impacts during drill penetration. The pad height can be precisely adjusted via the threaded engagement of the third bolt and connecting rod, allowing for flexible setting of the drilling depth. The flexible buffer design effectively reduces vibration at the drill end, lowers the probability of burrs at the hole opening, prevents drill bit chipping, and extends tool life. The depth adjustment operation is convenient and precise, meeting the requirements for mass production of highly consistent holes. Combined with the cooling and chip removal function of the coolant nozzle, it further improves drilling quality and processing efficiency.

[0036] The modular collaborative design of the conveyor and carrier box components ensures a smooth transition between workpiece loading and unloading, preventing jamming and offset caused by height differences. This enables automatic workpiece loading, positioning, and unloading, reducing manual intervention. The recessed space at the bottom of the carrier box accommodates bidirectional sliding module operation and collects coolant and chips for easy cleaning via a drain valve. The automated linkage of all components shortens the production cycle, reduces worker workload, maintains a clean production site, and enhances operational safety.

[0037] The modular design offers strong adaptability, optimizing operation and maintenance costs and lifecycle value. Utilizing a modular structure, the adaptive clamping component adapts to different widths and irregular shapes of guide rails via the scissor plate's telescopic stroke. The flexible limiting component adapts to different drilling depths via threaded adjustment. The conveying and carrying components adapt to different specifications of conveying mechanisms via plug-in connections. It can be compatible with the processing of various linear guide rail models without overall modification. The core transmission structure is mature and reliable, and the spring buffer design reduces component impact loss. The modular disassembly and assembly method reduces assembly and maintenance difficulty, decreases the frequency of core component replacement and troubleshooting time, significantly reducing long-term operation and maintenance costs and downtime losses. Simultaneously, the modular structure reserves installation space for future functional upgrades, greatly enhancing the device's applicability and lifecycle value. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Example: Please refer to Figure 1-15 The drilling device for machining linear guide rails shown includes a bidirectional sliding module 1 for driving and clamping, a fixing component 2 for fixing and guiding, a linkage clamping component 3 for performing clamping actions, a support component 4 for driving drill bit feed, a limiting component 5 for providing buffering and limiting, a drilling machine 6 as machining power, a carrier box component 7 as a base and collection unit, and a conveying component 8 for automatic loading and unloading.

[0042] Based on the aforementioned structural features and connection relationships, a collaborative automated drilling system is formed by combining specific mechanical interfaces and connectors.

[0043] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3As shown, the bidirectional sliding module 1 is the horizontal drive core of the entire device. It includes a clamping linear module 101 and two mounting plates 102. The clamping linear module 101 is preferably a bidirectional sliding module driven by a ball screw. Its two sliding ends can be controlled by the same drive source to achieve precise synchronous opposite or reciprocating movements. On each of the two sliding ends of the clamping linear module 101, a rectangular mounting plate 102 is rigidly connected by a set of internal hexagonal head bolts. The surfaces of the two mounting plates 102 are vertically opposite each other and can precisely move synchronously opposite or reciprocating linearly with the sliding ends, providing a power source and mounting base for subsequent clamping actions.

[0044] In this embodiment, specific references Figure 4 As shown, the two fixing components 2 are transition and reinforcement structures connecting the bidirectional sliding module 1 and the linkage clamping component 3. The two fixing components 2 are respectively fastened to the opposite side of the two mounting plates 102 by the first bolt 202. Each fixing component 2 mainly includes a "U"-shaped fixing plate 201, a vertical sliding plate 204, and a reinforcing plate 206 connecting the two. The vertical side plate of the fixing plate 201 is locked to the mounting plate 102 by the first bolt 202, and its horizontal bottom plate extends downward. The sliding plate 204 is fixed to the top outer side of the fixing plate 201 by welding or bolts. A T-shaped groove 205 is opened on its side along the vertical direction. The reinforcing plate 206 is welded to the right angle area formed by the fixing plate 201 and the sliding plate 204 to greatly enhance the torsional and bending stiffness of the connection part and ensure that it does not deform when subjected to clamping reaction force.

[0045] In this embodiment, specific references Figure 5 , Figure 6 and Figure 7As shown, a linkage clamping assembly 3 is provided for each fixed component 2. Each linkage clamping assembly 3 includes two sliders 301, two fixing blocks 302, a pin 304, and two intersecting scissor plates 305. The cross-sectional shape of the two sliders 301 is adapted to the T-shaped groove 205 on the slide plate 204, so that they can be embedded in the groove and slide smoothly along it, while preventing them from falling out. The two fixing blocks 302 are respectively fixed to the outer side of the two sliders 301 by bolts. Each fixing block 302 has a coaxial pin hole 303. The pin 304 passes through the pin holes 303 of the two fixing blocks 302, connecting the two and allowing them to rotate relative to each other. Each scissor plate 305 has a through hole 306 and a connecting hole 307 at both ends. The two scissor plates 305 overlap at the center and are hinged to a nut 309 by a long bolt 308 passing through the connecting hole 307 of the two, forming a telescopic "X"-shaped linkage mechanism. Each scissor plate 305 has a through hole 306 at one end (e.g., the upper end) connected to a pin hole 303 on a fixing block 302 via the aforementioned pin 304. That is, the upper ends of the two scissor plates 305 are respectively hinged to the two fixing blocks 302. The other end (lower end) of each scissor plate 305 is fixedly connected to a clamping block 3010. Rubber or polyurethane gaskets can be attached to the inner side of the clamping block 3010 to protect the workpiece surface. Its working principle is: when the two mounting plates 102 are subjected to bidirectional sliding... When the moving module 1 moves in opposite directions, it drives the two fixed components 2 and the two sliders 301 connected to them to slide in opposite directions in the slide groove 205. The movement of the sliders 301 is transmitted to the upper end of the scissor plate 305 through the pin 304, forcing the two intersecting scissor plates 305 to rotate around the hinge point in the middle, thereby driving the two clamping blocks 3010 connected to their lower ends to produce opposite linear motion, realizing automatic clamping of the linear guide rail placed in the middle. When moving in the opposite direction, the workpiece can be released.

[0046] In this embodiment, specific references Figure 8 and Figure 9 As shown, the support assembly 4 is used to realize the horizontal and vertical feed of the drilling rig. It includes a support plate 401, a lead screw linear module 403, and a hydraulic push rod 404. The support plate 401 is fixed to the top of the fixed plate 201 by a second bolt 402. The base (fixed end) of the lead screw linear module 403 is bolted to the top of the support plate 401. The movement direction of its slide (sliding end) is perpendicular to the movement direction of the bidirectional sliding module 1. The cylinder of the hydraulic push rod 404 is bolted vertically to the slide of the lead screw linear module 403. The lead screw linear module 403 can precisely adjust the drilling position of the drilling rig 6 in the horizontal direction (perpendicular to the length of the guide rail). The hydraulic push rod 404 can provide stable and powerful vertical downward feed power.

[0047] In this embodiment, specific references Figure 8 , Figure 10 , Figure 11 and Figure 12 As shown, the limiting component 5 is precisely connected to the output end of the hydraulic push rod 404. Its core function is to provide an adjustable and controllable mechanical stop for the drilling depth of the drill 6 and to ensure the smoothness of the drill bit during contact with and separation from the workpiece. This component mainly includes a connecting plate 501, two connecting rods 503, two third bolts 505, two pads 506, and two springs 507.

[0048] The connecting plate 501 is bolted to the end of the piston rod of the hydraulic push rod 404 through the mounting hole in its center. The connecting plate 501 has a through-hole 502 machined in its center, through which the output shaft of the drilling machine 6, i.e., the drill chuck, can pass freely. On both sides of the through-hole 502, there are two smooth cylindrical insertion holes 508 symmetrically machined. The drilling machine 6 is vertically and securely mounted on the top surface of the connecting plate 501 by bolts through its body flange or special clamp.

[0049] Two connecting rods 503 are inserted into two sockets 508 from below, and can slide up and down without interference within the sockets. Each connecting rod 503 has a threaded groove 504 machined on its top, and a disc-shaped pad 506 is coaxially welded to its bottom. The pad 506 is preferably a rubber damping pad. The third bolt 505 is screwed into the threaded groove 504 on the top of the connecting rod 503. Crucially, the outer diameter of the nut of the third bolt 505 and the diameter of the pad 506 are both designed to be larger than the diameter of the socket 508. This design ensures that the connecting rod 503 will not be pushed out of the socket 508 under the action of the spring 507. At the same time, the nut of the third bolt 505 provides an adjustable suspension point for the connecting rod 503 above the connecting plate 501.

[0050] The spring 507 is sleeved on the connecting rod 503 and positioned between the bottom surface of the connecting plate 501 and the top surface of the pad 506. In the initial state, before the drill bit contacts the workpiece, the spring 507 is subjected to a certain pre-compression force, which is adjusted by the depth to which the third bolt 505 is screwed in. The core mechanism of the spring 507 here is as follows: Cooperative rigid limiting: When the hydraulic push rod 404 drives the drill 6 to descend for drilling, after the drill bit penetrates the workpiece, the final pad 506 will contact the surface of the bearing plate 705 above or below the workpiece. At this time, the pad 506 becomes a rigid mechanical stop, preventing the connecting rod 503 from continuing to descend. Since the connecting rod 503 is connected to the connecting plate 501 through the third bolt 505 and the spring 507, the connecting plate 501 and the drill 6 mounted on it are also restricted from continuing to descend, thereby precisely controlling the final depth of drilling.

[0051] Providing constant contact pressure and eliminating gaps: During drilling, the preload of spring 507 acts continuously on the workpiece or bearing surface through pad 506, ensuring the stability of the limiting contact and eliminating depth errors that may be caused by mechanism gaps. This elastic contact method is more beneficial to protecting the equipment and workpiece surface than pure rigid collision.

[0052] Achieving smooth stroke transition: When the hydraulic push rod 404 retracts after drilling is completed, the restoring force of the spring 507 can smoothly push the connecting plate 501 and the drill 6 to rise together with the connecting rod 503, ensuring that the drill bit exits the workpiece cleanly and neatly, avoiding jamming or scratching.

[0053] In addition, a coolant nozzle 9 is installed on the bottom surface of the connecting plate 501. Its nozzle is aimed at the working part of the drill bit and is used to spray coolant during drilling to cool, lubricate and remove chips.

[0054] In this embodiment, specific references Figure 13 and Figure 14 As shown, the carrier box assembly 7 is located at the bottom of the entire device and is used to collect coolant, chips, and carry workpieces. It includes a carrier box 701 with a box structure, a drain valve 704, a carrier plate 705, and multiple support legs 706. The top two sides of the carrier box 701 have elongated slots 702 for installing the conveying assembly 8. The bottom middle area of ​​the carrier box 701 is recessed inward to form a "U"-shaped clearance space, allowing the bottom of the bidirectional sliding module 1 and the fixing plate 201 below it to extend into it, reducing the overall height of the device. The height and center of gravity are adjusted for a more compact structure. The drain valve 704 is installed at the lowest point of the bottom of the support box 701 for periodically discharging accumulated waste liquid. The support plate 705 is horizontally fixed to the inner wall of the support box 701 by bolts, located above the recessed space, for directly supporting the linear guide rail being processed. The upper surface of the support plate 705 is also provided with a clearance groove flush with the belt surface of the small belt conveyor 802 to ensure smooth transition of workpiece transport. The support legs 706 are welded to the four corners of the bottom of the support box 701 to support the entire device and adjust its level.

[0055] In this embodiment, Figure 14 and Figure 15As shown, the conveying assembly 8 is used for automatic loading and unloading. It includes two insert plates 801, a small belt conveyor 802, two wedge blocks 803, and a fourth bolt 804. The frame of the small belt conveyor 802 is fixed between the two insert plates 801. The wedge blocks 803 are welded to the lower inner side of each insert plate 801, and their inclined surfaces help guide the insert plates 801 into the slots 702. During installation, the two insert plates 801 are inserted into the slots 702 at the top of the carrier box 701. The wedge block 803 is engaged inside the slot for initial positioning. Then, the fourth bolt 804 is passed through the hole at the top of the insert plate 801 from top to bottom and tightened into the threaded hole 703 pre-drilled at the top of the carrier box 701, thereby firmly fixing the conveying assembly 8 onto the carrier box. The head of the fourth bolt 804 is designed to be countersunk or flush with the top surface of the insert plate to avoid interfering with the conveying of the workpiece. A certain gap is left between the wedge block 803 and the conveying edge of the insert plate 801, which allows the end of the linear guide rail to pass through, ensuring smooth conveying.

[0056] The working process of this invention is as follows: The first step is installation and loading. Insert the insert plate 801 of the conveyor assembly 8 into the slot 702 of the carrier box assembly 7 and lock it in place with the fourth bolt 804. Place the linear guide rail to be drilled on the belt of the small belt conveyor 802, start the conveyor, and automatically transport the linear guide rail into the carrier box 701 and stop it precisely at the set processing position of the carrier plate 705.

[0057] The second step is automatic clamping. The bidirectional sliding module 1 is activated, which drives the two mounting plates 102 to move the two fixing components 2 toward each other. The movement of the fixing components 2 forces the two sliders 301 to slide toward each other in their respective T-shaped slide grooves 205. Through the linkage between the pin 304 and the scissor plate 305, the horizontal movement of the slider is converted into the linear movement of the two clamping blocks 3010 toward each other, thereby firmly clamping the linear guide rail from both sides and completing automatic centering and fixing.

[0058] The third step is positioning and drilling. According to the requirements of the machining hole position, the lead screw linear module 403 of the support component 4 is started, which drives the hydraulic push rod 404, the limiting component 5 and the drill 6 to move horizontally, so that the drill bit is aligned with the pre-drilled hole position on the linear guide. Then, the hydraulic push rod 404 is started to push the drill 6 and the limiting component 5 to descend as a whole. The drill bit contacts the workpiece and begins to drill. When the pad 506 contacts the workpiece or the bearing surface, the spring 507 is compressed, which provides stable drilling pressure and plays the role of stroke buffer and final limit. At the same time, the coolant nozzle 9 sprays coolant to cool the drill bit and wash away the chips.

[0059] The fourth step is resetting and unloading. After drilling is completed, the hydraulic push rod 404 retracts, driving the drill 6 to rise and reset. Then, the bidirectional sliding module 1 reverses its drive, causing the linkage clamping assembly 3 to release the processed linear guide rail. Finally, the small belt conveyor 802 is started again to send the processed linear guide rail out of the carrier box, completing one processing cycle. Chips and coolant waste are collected at the bottom of the carrier box 701, and the drain valve 704 can be opened periodically for cleaning.
