Description

Technical Field

[0001] This application relates to the technical field of linear guide rail processing, and more particularly to a linear guide rail double-sided synchronous drilling device. Background Technology

[0002] Linear guides are important guiding and load-bearing components in linear motion systems, and are widely used in automation equipment, CNC equipment, and machining equipment. During the manufacturing process, linear guides typically require multiple mounting holes to be drilled along their length to secure them to a suitable mounting base using connectors.

[0003] Existing equipment typically stops the drive mechanism after the drilling mechanism moves to the predetermined processing position before drilling begins; after drilling is completed, the drive mechanism is restarted to move the drilling mechanism to the next processing position. Using this method, there is a lack of effective coordinated control between the movement and positioning of the drilling mechanism and the drilling feed. When the drill begins to advance, if the drive mechanism does not stop in time or the power transmission is not released in time, the drilling mechanism may still move along the length of the linear guide, causing additional positional offset during the feed process. This can lead to drilling position deviation, unstable drilling depth, or even jamming or damage to the drill due to lateral forces.

[0004] To avoid the above situation, existing equipment typically requires stopping the drive mechanism after the drilling mechanism reaches the machining position and restarting the drive mechanism after drilling is completed. As the number of machined holes increases, the drive mechanism needs to be started and stopped frequently, subjecting the drive mechanism and transmission components to repeated mechanical shocks from starting and stopping. This not only increases the wear of transmission components but also affects the long-term stability and service life of the drive mechanism. Summary of the Invention

This application achieves coordinated control of drilling propulsion and power transmission through the cooperation of the driving components, transmission components and linkage components in the drive mechanism; when drilling begins, the linkage components and linkage components cooperate to cut off the power transmission in time, avoiding the continuous movement of the slide table from causing over-drilling or damage to the drill feed, thus improving the safety and reliability of equipment operation, and at the same time avoiding frequent start and stop of the drive mechanism, which would affect the service life of the drive mechanism. 3.

Detailed Implementation

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The following description, in conjunction with the accompanying drawings, describes a linear guide double-sided synchronous drilling device according to an embodiment of this application.

[0021] like Figures 1 to 10 As shown, this embodiment provides a linear guide rail double-sided synchronous drilling device, mainly used for machining mounting holes on linear guide rails. During operation, the linear guide rail is placed along its length within the machining area of ​​the work frame 1 and clamped and positioned by the pressing component 2. The drilling mechanism 3 moves along the length of the linear guide rail under the power provided by the drive mechanism 4. After moving to the predetermined drilling position, the drill bit 333 in the drilling mechanism 3 synchronously advances from both sides of the linear guide rail towards the center, thus completing the synchronous machining of corresponding holes on both sides of the linear guide rail in a single clamping state. Furthermore, during the drilling process, there is no need to frequently start and stop the drive mechanism 4 to lock the position and control the feed of the drilling mechanism 3, effectively reducing the energy consumption and mechanical wear of the drive mechanism 4.

[0022] The work frame 1 forms the overall mounting base for the equipment. It contains internal partitions and limit rods. A sliding groove is also provided on the work frame 1 to guide the movement of the mounting plate 32. A slide table 31 is located inside the work frame 1 and slides in cooperation with the limit rods. The mounting plate 32 passes through the sliding groove on the work frame 1 and connects to the slide table 31, allowing the mounting plate 32 to move along the length of the linear guide rail with the slide table 31. The limit rods guide the slide table 31, reducing lateral offset during movement and ensuring a stable trajectory for the mounting plate 32 and the drilling mechanism 3 mounted on it.

[0023] It should be noted that a fixed platform is installed on the work frame 1, and when the linear guide is being drilled, one end of the guide is placed on the fixed platform by a feeding device (not shown in the figure), and the guide is fixed by two sets of limiting blocks installed on the fixed platform (the distance between the two sets of limiting blocks can be adjusted to accommodate different guide widths) to prevent the guide from axially moving during the processing. The bottom surface of the linear guide is in contact with the mounting plate 32 to ensure stable support of the linear guide during drilling.

[0024] In this embodiment, as Figure 3 As shown, before processing, the linear guide rail to be processed is placed in the processing area of ​​the work frame 1, and the linear guide rail is pressed by the pressing assembly 2. The pressing assembly 2 includes a mounting frame 21, a hydraulic rod 22, and a pressing wheel 23. The mounting frame 21 is fixedly mounted on the work frame 1, the hydraulic rod 22 is mounted on the mounting frame 21, and the extended end of the hydraulic rod 22 is set towards the work frame 1. The pressing wheel 23 is mounted on the extended end of the hydraulic rod 22.

[0025] After the linear guide rail is placed, the hydraulic rod 22 drives the pressing wheel 23 to move downwards, causing the pressing wheel 23 to contact the linear guide rail and apply a clamping force. Since the pressing wheel 23 and the linear guide rail are in rolling contact, this ensures stable pressing of the linear guide rail without significantly hindering the subsequent movement of the drilling mechanism 3 along the length of the linear guide rail. When processing linear guide rails of different thicknesses, the clamping position of the pressing wheel 23 can be adjusted by changing the extension length of the hydraulic rod 22, allowing the equipment to adapt to linear guide rails of different specifications.

[0026] In this embodiment, as Figures 7-9 As shown, after the linear guide rail is fixed, the drive mechanism 4 begins to operate. The drive mechanism 4 includes a drive component 41, a transmission assembly 42, and a linkage assembly 43. The drive component 41 is mounted on the work frame 1 and provides continuous rotational power to the transmission assembly 42. The transmission assembly 42 converts the rotational power output by the drive component 41 into the reciprocating motion power of the slide table 31, and controls the power transmission state according to the drilling process through the linkage assembly 43.

[0027] Specifically, such as Figure 7 and Figure 8 As shown, the transmission assembly 42 includes a transmission rod 421, a spring 422, a first end-face meshing gear 423, a second end-face meshing gear 424, and a reciprocating screw 425. The transmission rod 421 passes through the work frame 1 and is connected to the output end of the drive member 41. After the drive member 41 is started, it drives the transmission rod 421 to rotate. The first end-face meshing gear 423 is slidably mounted on the transmission rod 421 via a slide plate 426, so that the first end-face meshing gear 423 can both rotate with the transmission rod 421 and change position along the axial direction of the transmission rod 421. The spring 422 is sleeved on the transmission rod 421, and its two ends are connected to the first end-face meshing gear 423 and the transmission rod 421 respectively, and is used to provide a reset function after the first end-face meshing gear 423 is pushed by an external force.

[0028] The reciprocating screw 425 is rotatably mounted on the work frame 1 and meshes with the first end-face meshing gear 423 via the second end-face meshing gear 424. Thus, when the transmission rod 421 rotates, it drives the first end-face meshing gear 423 to rotate synchronously, and the power is transmitted to the reciprocating screw 425 through the meshing relationship between the first end-face meshing gear 423 and the second end-face meshing gear 424, causing the reciprocating screw 425 to rotate. The slide table 31 is driven by the reciprocating screw 425, so when the reciprocating screw 425 rotates, it can push the slide table 31 to move axially, and further drive the mounting plate 32 and the drilling mechanism 3 to move along the length of the linear guide rail.

[0029] It should be noted that the drive unit 41 described in the above embodiment consists of a drive motor and a reducer, and its output end is connected to the transmission rod 421 through a coupling.

[0030] It should be noted that by adopting the above structure, the drive unit 41 does not need to be repeatedly started and stopped for each drilling position, but can continuously provide rotational power, and the reciprocating screw 425 controls the drilling mechanism 3 to feed according to a predetermined movement trajectory. This can reduce the mechanical shock caused by frequent start and stop of the drive unit 41, and make the movement process between multiple drilling positions more continuous.

[0031] In this embodiment, as Figures 4-6 As shown, after the drilling mechanism 3 moves to the predetermined processing position along with the slide table 31, the advancing drilling assembly 33 begins drilling holes in the linear guide rail. The drilling mechanism 3 includes a slide table 31, a mounting plate 32, an advancing drilling assembly 33, and a guide member 34. The mounting plate 32 is connected to the slide table 31 and can move along a groove on the work frame 1. The advancing drilling assembly 33 is mounted on the mounting plate 32. The guide member 34 is mounted on the work frame 1 and is used to assist the tension 3347 in controlling the transmission assembly 42, so that the tension rope 3347 can maintain a reasonable movement path during the movement and advancement of the drilling mechanism 3.

[0032] It should be noted that the guide 34 described in the above embodiment consists of a support frame and a guide wheel, and the guide wheel has an annular groove in the middle for the pull rope 3347 to be inserted, so as to prevent the pull rope from deviating during the guiding process.

[0033] Furthermore, such as Figure 4 As shown, the drilling assembly 33 includes a propulsion component 331, a limiting frame 332, a drill bit 333, and a linkage component 334. The propulsion component 331 and the limiting frame 332 are both mounted on a mounting plate 32. The drill bit 333 is mounted on the propulsion component 331. The mounting plate 32 has a groove for the drill bit 333 to move, allowing it to move towards the linear guide under the drive of the propulsion component 331. The linkage component 334 is mounted on the mounting plate 32 and is used to associate the propulsion action of the drill bit 333 with the power cutting action of the drive mechanism 4.

[0034] In this embodiment, as Figure 7 As shown, when the drilling mechanism 3 moves to the set processing position, the propulsion component 331 begins to operate. The propulsion component 331 includes a hydraulic cylinder 3311, a hinge frame 3312, a hinge rod 3313, and a centering plate 3314. The hydraulic cylinder 3311 is mounted on the mounting plate 32, and its extended end is connected to the hinge frame 3312; the hinge frame 3312 is slidably connected to the limiting frame 332, thereby enabling the hinge frame 3312 to move stably in a predetermined direction. The centering plate 3314 is slidably disposed on the mounting plate 32, and the hinge frame 3312 is hinged to the centering plate 3314 via the hinge rod 3313.

[0035] During drilling, the extended end of the hydraulic cylinder 3311 retracts, causing the hinge frame 3312 to move along the limiting frame 332. Since one end of the hinge rod 3313 is connected to the hinge frame 3312 and the other end is connected to the centering plate 3314, the linear movement of the hinge frame 3312 can be converted into relative movement of the centering plate 3314. The centering plate 3314 and the drill 333 are linked, enabling the drills 333 located on both sides of the linear guide rail to move towards the linear guide rail synchronously.

[0036] During actual machining, the drills 333 in both directions correspond to the machining positions on both sides of the linear guide. After the hydraulic cylinder 3311 is activated, the hinge frame 3312 moves and drives the centering plate 3314 to move through the hinge rod 3313, so that the drills 333 on both sides advance synchronously. Since the drills 333 on both sides are controlled by the same advancing action, the corresponding holes on both sides can be machined simultaneously while the linear guide is kept fixed, without having to machine one side first, disassemble the linear guide, and then flip it to machine the other side.

[0037] The above-mentioned synchronous propulsion method not only shortens the processing cycle, but also reduces the positional offset caused by re-clamping because the holes on both sides are processed in the same clamping and under the same reference state. This helps to ensure the positional relationship and coaxiality between the corresponding mounting holes on both sides of the linear guide.

[0038] To further illustrate the above embodiments, in this embodiment, as... Figure 4 and Figure 6 As shown, during the process of the drill 333 advancing towards the linear guide rail, the linkage component 334 operates synchronously. The linkage component 334 includes a pressing plate 3341, a mounting box 3342, an elastic winding box 3343, an elastic telescopic rod 3344, a docking plate 3345, a connecting plate 3346, and a pull rope 3347.

[0039] The connecting plate 3346 is connected to the hinge frame 3312, and the pressing plate 3341 is mounted on the connecting plate 3346. The mounting box 3342 is mounted on the mounting plate 32. The mounting plate 32, the limiting frame 332, and the mounting box 3342 are all provided with through slots for the connecting plate 3346 to slide, so that the connecting plate 3346 can pass through the above structure as the hinge frame 3312 moves and drive the pressing plate 3341 to move. The elastic telescopic rod 3344 is mounted on the mounting box 3342, and the docking plate 3345 is mounted on the telescopic end of the elastic telescopic rod 3344, so that the docking plate 3345 can generate corresponding displacement when subjected to compressive force and return to its original position after the external force is released.

[0040] The flexible winding box 3343 is mounted on the mounting plate 32. One end of the pull rope 3347 is connected to the flexible winding box 3343, and the other end passes through the docking plate 3345, the extrusion plate 3341, and the guide 34 in sequence before connecting to the linkage assembly 43. The guide 34 guides the pull rope 3347, enabling it to move in a predetermined direction during the drilling process of the drill 333, while reducing interference between the pull rope 3347 and other structures.

[0041] When the hydraulic cylinder 3311 retracts, it moves the articulated frame 3312 and the connecting plate 3346. The pressing plate 3341 moves synchronously with the connecting plate 3346 and gradually presses the pull rope 3347 and the docking plate 3345. After the docking plate 3345 is pressed, it causes the elastic telescopic rod 3344 to extend and retract, while the pull rope 3347 is pulled. The traction of the pull rope 3347 is further transmitted to the linkage component 43, which interrupts the power transmission in the transmission component 42, thus preventing the slide table 31 from moving continuously and ensuring the stability of the drill 333 during the drilling process. After drilling is completed, when the hydraulic cylinder 3311 extends and drives the hinge frame 3312 and the connecting plate 3346 to move, the pressing plate 3341 moves synchronously with the connecting plate 3346, thereby gradually reducing the pressing force on the pull rope 3347 and the docking plate 3345, causing the elastic telescopic rod 3344 to drive the docking plate 3345 to reset. At the same time, the traction force of the pull rope 3347 is released, and the linkage component 43 resumes power transmission. During the reset process, the tension of the pull rope 3347 is released and retracts to the elastic winding box 3343, preventing the pull rope 3347 from slack and affecting the accuracy of the next linkage.

[0042] Furthermore, such as Figure 9 As shown, the linkage assembly 43 is located on the partition inside the work frame 1, and includes a movable frame 431, an abutment rod 432, a hinge frame 433, and a push rod 434. The abutment rod 432 is slidably mounted on the partition inside the work frame 1. One end of the movable frame 431 is hinged to the abutment rod 432, and the other end is movably connected to the first end face meshing gear 423. The hinge frame 433 is mounted on the partition, and the middle part of the push rod 434 is hinged to the hinge frame 433, while the top end of the push rod 434 is hinged to the abutment rod 432.

[0043] It should be noted that, as Figure 10 As shown, the hinged connection between the movable frame 431 and the abutment rod 432 described in the above embodiment can be a pin connection. The movable frame 431 has a through groove in the middle for the pin to slide up and down, thereby preventing the abutment rod 432 from tilting upward at the end connected to the movable frame 431 and rubbing against the baffle when pushed by the push rod 434, which would prevent the power from being transmitted to the movable frame 431 and thus affect the axial movement control of the first end face meshing gear 423.

[0044] As the pull rope 3347 is pulled, the linkage assembly 43 is subjected to tension, causing the abutment rod 432 to move along the partition and changing the axial position of the first end face meshing gear 423 on the transmission rod 421 via the moving frame 431. When the first end face meshing gear 423 moves axially, the meshing state between the first end face meshing gear 423 and the second end face meshing gear 424 changes, causing the first end face meshing gear 423 and the second end face meshing gear 424 to disengage, interrupting the continuous transmission of power, resulting in the first end face meshing gear 423 and the second end face meshing gear 424 being in a separated state, thereby controlling the power transmission between the drive member 41 and the reciprocating screw 425.

[0045] It should be noted that, in order to avoid tooth knocking between the first end face meshing gear 423 and the second end face meshing gear 424 when resuming transmission, a synchronizer (not shown in the figure) can be installed between the first end face meshing gear 423 and the second end face meshing gear 424 to avoid tooth knocking between them.

[0046] When the drilling mechanism 3 reaches the machining position and begins to advance the drill 333, the drive component 41 continues to operate. However, the linkage component 43 disengages the first end-face meshing gear 423 from the second end-face meshing gear 424, interrupting the continuous transmission of power and causing the reciprocating screw 425 to stop driving the slide 31. At this time, the drilling mechanism 3 remains in the current machining position, and the drill 333 is mainly controlled by the propulsion component 331 to advance towards the linear guide rail. This prevents the slide 31 from continuing to move after the drill 333 has approached the machining position, thus avoiding over-drilling, jamming, or damage to the drill 333 due to additional feed.

[0047] After a single hole is machined, the hydraulic cylinder 3311 stops retracting and extends to reset. The hinge frame 3312 gradually returns to its initial position, and the center plate 3314 resets synchronously under the action of the hinge rod 3313. The drill 333 then moves away from the linear guide. At the same time, the pressing plate 3341 releases its pressure on the mating plate 3345, and the elastic telescopic rod 3344 returns to its initial state.

[0048] It should be noted that one end of the tensioning 3347 passes through the extrusion plate 3341 and is positioned around the bottom of the docking plate 3345. An inclined plate is installed in the middle of the extrusion plate 3341, which faces the bottom of the docking plate 3345. When the extrusion plate 3341 retracts with the hydraulic cylinder 3311, the extrusion plate 3341 moves toward the docking plate 3345, and the inclined surface of the inclined plate and the bottom surface of the docking plate 3345 clamp the tensioning rope 3347. Thus, the tensioning 3347 controls the action of the linkage component 43 to achieve the blocking of power transmission.

[0049] As the traction force on the pull rope 3347 is gradually released, the elastic winding box 3343 can elastically wind the pull rope 3347, keeping it taut again and preventing it from becoming loose, sagging, or tangled during the mechanism's reset process. During the pull rope 3347's retraction, the linkage component 43 synchronously recovers, and the first end face meshing gear 423 moves back to a position where it can transmit power to the second end face meshing gear 424, so that the first end face meshing gear 423 and the second end face meshing gear 424 are engaged, thus re-driving the slide table 31.

[0050] It should be noted that the structure of the elastic winding box 3343 described in the above embodiments is prior art, so it will not be described in detail here (e.g., measuring tape).

[0051] After the power is transmitted again, the drive unit 41 drives the reciprocating screw 425 to rotate again through the transmission rod 421, the first end face meshing gear 423, and the second end face meshing gear 424. The slide table 31 continues to move to the next machining position with the reciprocating screw 425. By repeating this cycle, multiple mounting holes in the length direction of the linear guide can be machined sequentially.

[0052] Since the advancing motion of the drill 333 and the moving motion of the slide 31 are controlled by the advancing component 331 and the driving mechanism 4 respectively, in one machining cycle, the slide 31 mainly undertakes the movement between drilling positions, the advancing component 331 mainly undertakes the machining feed of the drill 333 towards the workpiece, and the linkage component 334 and the linkage assembly 43 are responsible for establishing the mechanical linkage between the two actions. This enables the equipment to form a continuous machining process of "movement positioning—power cut-off—double-sided advancement—drilling completion—drill 333 retraction—power restoration—movement to the next position".

[0053] After the linear guide rail is machined, the hydraulic rod 22 drives the pressing wheel 23 to retract upwards, releasing the pressure on the linear guide rail, allowing the operator to remove the machined linear guide rail. The linear guide rail to be machined is then placed back in, and the next round of machining can begin.

[0054] In some alternative embodiments, the pressing rollers 23 can be configured in multiples according to the specific structure of the linear guide rail, and arranged at intervals along the length of the linear guide rail to further improve the stability during the pressing process. The hydraulic rods 22 can also be replaced with electric push rods or pneumatic actuators according to the equipment specifications, as long as they can drive the pressing rollers 23 to reliably press the linear guide rail.

[0055] In some alternative embodiments, the hydraulic cylinder 3311 in the propulsion component 331 can be replaced with an electric linear actuator or a pneumatic actuator depending on the processing cycle and drilling load; the articulated frame 3312, the articulated rod 3313 and the centering plate 3314 can still adopt an articulated transmission method to synchronously transmit the linear motion of the actuator to the drill 333, thereby maintaining the double-sided synchronous propulsion function.

[0056] In some optional embodiments, the first end-face meshing gear 423 and the second end-face meshing gear 424 in the transmission assembly 42 can be implemented using a mechanical transmission structure with power engagement and disengagement functions, depending on specific transmission requirements, as long as the power transmission state between the drive member 41 and the reciprocating screw 425 can be changed under the action of the linkage assembly 43. The spring 422 is used to provide the reset function of the first end-face meshing gear 423, and its specific installation form can be adjusted according to the structure of the transmission rod 421.

[0057] In some alternative embodiments, the guide 34 may be a roller, guide wheel, or other structure capable of limiting and supporting the pull rope 3347 to reduce frictional resistance during the movement of the pull rope 3347. The elastic winding box 3343 may also be a winding structure with an automatic winding function to ensure that the pull rope 3347 maintains appropriate tension under different working conditions.

[0058] In summary, this embodiment achieves synchronous machining of mounting holes on both sides of the linear guide rail by means of mechanical coordination between the work frame 1, the pressing assembly 2, the drilling mechanism 3, and the drive mechanism 4, while maintaining a single clamping operation. The pressing assembly 2 uses a hydraulic rod 22 to drive the pressing wheel 23 to stably clamp the linear guide rail, reducing workpiece movement during machining. The drive mechanism 4 uses a drive member 41, a transmission rod 421, a first end face meshing gear 423, a second end face meshing gear 424, and a reciprocating screw 425 to move the slide table 31 and the mounting plate 32 along the machining direction, achieving automatic feeding between multiple hole positions. The advancing drilling assembly 33 uses a hydraulic cylinder 3311, a hinge frame 3312, a hinge rod 3313, and a centering plate 3314 to synchronously bring the drills 333 on both sides closer to the linear guide rail, thereby reducing clamping errors caused by workpiece flipping and improving the correspondence accuracy of the double-sided hole positions.

[0059] Simultaneously, the linkage component 334 transmits the drilling propulsion action to the linkage assembly 43 via the pressing plate 3341, connecting plate 3346, elastic telescopic rod 3344, docking plate 3345, and pull rope 3347. The linkage assembly 43 then controls the axial position of the first end face meshing gear 423 via the moving frame 431, abutting rod 432, hinge frame 433, and push rod 434, thus forming a mechanical linkage between the drilling propulsion and the movement of the slide table 31. During the drilling stage, the reciprocating screw 425 is promptly restricted from continuing to drive the slide table 31, and power transmission is resumed after drilling is completed and reset, thereby reducing the adverse effects of over-drilling and frequent start-stop of the drive component 41. The elastic winding box 3343 can automatically wind up the pull rope 3347 after processing, restoring the linkage structure to the state required for the next processing cycle.

[0060] Therefore, this application can achieve simultaneous drilling on both sides without flipping the linear guide rail, and improve the consistency and continuous processing efficiency of the machining of both sides of the linear guide rail by coordinating the control between positioning movement, double-sided propulsion and power cutting, while reducing positioning errors and manual operation caused by repeated clamping, and has a good automated processing effect.
