Description

Technical Field

[0001] This invention relates to the field of guide rail processing technology, and in particular to a guide rail drilling machine. Background Technology

[0002] In the production process of linear guides, it is necessary to drill holes for mounting the linear guides. The guide workpiece is fixed on the worktable, and the drilling machine drills the holes in the guide workpiece. However, due to the limitations of the drilling machine structure, the worktable is usually supported on only one side, forming a cantilever structure. In this way, when drilling the guide workpiece, the worktable does not have balanced support on both sides, which leads to displacement and deformation of the worktable. This can easily cause errors in the drilling of the guide rail and affect the product quality. Summary of the Invention

The base is provided with a worktable for fixing the guide rail workpieces. The moving device includes a saddle, a longitudinal drive mechanism, a column, a transverse drive mechanism, and a vertical drive mechanism. The saddle is movably mounted on the base. The longitudinal drive mechanism is mounted on the base and can drive the saddle to move along the length of the base. The movable support plate is fixed to the saddle.

The output end of the vertical drive mechanism is provided with a mounting base for mounting the drilling machines.

[0006] As a preferred embodiment of the present invention, the column is provided with a plurality of adjustment mechanisms for adjusting the spacing between the drilling machines. The number of adjustment mechanisms is the same as the number of vertical drive mechanisms, and the adjustment mechanisms and the vertical drive mechanisms are arranged in a one-to-one correspondence. Alternatively, the number of adjustment mechanisms is one less than the number of vertical drive mechanisms, and one adjustment mechanism corresponds to one vertical drive mechanism.

[0007] The adjustment mechanism includes an adjustment seat, an adjustment guide rail, and an adjustment driver. The adjustment guide rail is disposed on the column along the longitudinal direction of the base. The vertical drive mechanism includes a vertical driver and a vertical guide rail. The vertical guide rail is disposed on the adjustment seat along the height direction of the base. The mounting seat is slidably connected to the adjustment seat via the vertical guide rail. The output end of the vertical driver is connected to the mounting seat and can drive the mounting seat to move on the adjustment seat. The adjustment guide rail is disposed on the column along the longitudinal direction of the base. The adjustment driver is mounted on the column. The output end of the adjustment driver is connected to the adjustment seat and drives the adjustment seat to move on the adjustment guide rail.

[0008] As a preferred embodiment of the present invention, the worktable is provided with clearance holes that match the mounting holes in various types of guide rail workpieces, and the diameter and spacing of the mounting holes of different types of guide rail workpieces are different.

[0009] As a preferred embodiment of the present invention, a plurality of reinforcing ribs are connected between the movable pallet and the column, and the plurality of reinforcing ribs are arranged at intervals along the length direction of the base.

[0010] As a preferred embodiment of the present invention, it further includes a pressing device, which includes a pressing bracket, a pressing roller, and a pressing driver. The pressing bracket is connected to the moving device, and the moving device can drive the pressing bracket to move along the length and width directions of the machine base. The pressing driver is disposed on the pressing bracket, and the output end of the pressing driver is rotatably connected to the pressing roller and drives the pressing roller to move vertically along the height direction of the machine base.

[0011] As a preferred embodiment of the present invention, a chamfering device for chamfering the bottom of the hole of the guide rail workpiece is provided below the worktable, and the chamfering device is connected to the column.

[0012] As a preferred embodiment of the present invention, the workbench includes a table surface and a clamping assembly.

At the same time, the movable support plate, which is set accordingly, avoids the possibility of interference with other mechanisms.

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4As shown, a guide rail drilling machine of the present invention includes a base 2, a moving device 4, a movable support plate 5, and a drilling device 3 for drilling holes in a guide rail workpiece 1. The drilling device 3 is used to process mounting holes in the guide rail workpiece 1. The base 2 is provided with a worktable 21 for fixing the guide rail workpiece 1. The moving device 4 includes a saddle 411, a longitudinal drive mechanism, a column 421, a transverse drive mechanism, and a vertical drive mechanism. The saddle 411 is movably mounted on the base 2. The longitudinal drive mechanism is mounted on the base 2 and can drive the saddle 411 to move along the length direction of the base 2. The movable support plate 5 is fixed on the saddle 411. The column 421 is movably mounted on the saddle 411. The transverse drive mechanism is mounted on the saddle 411 and can drive the column 421 to move along the width direction of the base 2. The drilling device 3 is movably mounted on the worktable 2. The vertical drive mechanism is mounted on the column 421 and can drive the drilling device 3 to move along the height direction of the base 2. The two sides of the worktable 21 in the width direction are fixedly supported by the support frame 22 of the base 2 and movably supported by the movable pallet 5. The length of the support frame 22 is greater than or equal to the length of the worktable 21, and the length of the movable pallet 5 is less than the length of the worktable 21. The movable pallet 5 is located below the drilling device 3. At the same time, the movable pallet 5 and the drilling device 3 are synchronized in the length and width directions of the base 2, and can support the area on the worktable 21 where drilling is being performed through the movable pallet 5. Furthermore, the top surface of the movable pallet 5 is in close contact with the bottom surface of the worktable 21, and the top surface of the movable pallet 5 is provided with a pad with a low coefficient of friction to reduce the frictional impact between the movable pallet 5 and the worktable 21.

[0024] Finite element analysis showed that when drilling the guide rail workpiece 1, the displacement deformation of the worktable 21 supported on only one side exceeded 0.2 mm. However, under the same drilling force, after adding the movable support plate 5 of the present invention, the worktable 21 was effectively supported on both sides, and its displacement deformation was reduced to within 0.03 mm, which greatly improved the support rigidity of the worktable 21 and improved the drilling quality of the guide rail workpiece 1.

[0025] This invention supports the worktable 21 by setting a movable support plate 5. Since the movable support plate 5 moves synchronously with the drilling device 3 along the length of the machine base 2, it ensures that the area where the movable support plate 5 supports the worktable 21 is always located at the position where the drilling device 3 drills the guide rail workpiece 1. At the same time, the movable support plate 5, which is set to move along with the machine base 2, avoids the possibility of interference with other mechanisms. Under the support of the movable support plate 5 and the support frame 22 on both sides of the machine base 2, the deformation of the worktable 21 caused by drilling the guide rail workpiece 1 is effectively reduced, which greatly improves the support rigidity of the worktable 21 and improves the product processing quality.

[0026] For example, the drilling device 3 includes multiple drilling machines 31, forming a high-efficiency multi-spindle linear guideway drilling device 3, which can drill multiple holes on the guideway workpiece 1 at one time, improving drilling efficiency. The drilling device 3 has a cantilever structure, ensuring that multiple drilling machines 31 can be arranged along the length direction of the machine base 2, and the movable support plate 5 can effectively support the worktable 21 with high force. The vertical drive mechanism is provided with multiple vertical drive mechanisms, which are arranged one-to-one with the drilling machines 31. The output end of the vertical drive mechanism is provided with a mounting base 431 for mounting the drilling machines 31, and each drilling machine 31 can be individually adjusted in height.

[0027] For example, the column 421 is provided with multiple adjustment mechanisms for adjusting the spacing between the drilling machines 31. The number of adjustment mechanisms is the same as the number of vertical drive mechanisms, and the adjustment mechanisms are arranged in a one-to-one correspondence with the vertical drive mechanisms (i.e., each drilling machine 31 can move and adjust its position to adjust the spacing between the drilling machines 31). Alternatively, the number of adjustment mechanisms is one less than the number of vertical drive mechanisms, and one adjustment mechanism corresponds to one vertical drive mechanism (i.e., one vertical drive mechanism is fixedly installed on the column 421, and the remaining vertical drive mechanisms are arranged in a one-to-one correspondence with the adjustment mechanisms, with one drilling machine 31 as a reference that remains stationary, while the remaining drilling machines 31 move and adjust their positions to adjust the spacing between the drilling machines 31). Preferably, one vertical drive mechanism located at the head end of the column 421 is installed on the column 421, and the remaining vertical drive mechanisms are respectively connected to the column 421 through corresponding adjustment mechanisms. (Connection), the number of adjustment mechanisms can be selected according to actual conditions; the adjustment mechanism includes an adjustment seat 441, an adjustment guide rail 442, and an adjustment driver 443. The adjustment guide rail 442 is arranged on the column 421 along the longitudinal direction of the base 2. The vertical drive mechanism includes a vertical driver and a vertical guide rail 432. The vertical guide rail 432 is arranged on the adjustment seat 441 along the height direction of the base 2. The mounting seat 431 is slidably connected to the adjustment seat 441 through the vertical guide rail 432. The output end of the vertical driver is connected to the mounting seat 431 and can drive the mounting seat 431 to move on the adjustment seat 441. The adjustment guide rail 442 is arranged on the column 421 along the longitudinal direction of the base 2. The adjustment driver 443 is mounted on the column 421. The output end of the adjustment driver 443 is connected to the adjustment seat 441 and drives the adjustment seat 441 to move on the adjustment guide rail 442. Specifically, each of the aforementioned adjustment seats 441 is located on the same plane (and each drilling machine 31 on the drilling device 3 is located on the same plane). The adjustment guide rails 442 on all adjustment mechanisms are the same adjustment guide rail 442, that is, all adjustment mechanisms share the same adjustment guide rail 442. The adjustment driver 443 includes a handwheel and a lead screw pair connected to the handwheel. The handwheel is rotatably connected to the column 421 through a bearing seat. The lead screw nut of the lead screw pair is connected to the adjustment seat 441, so that rotating the handwheel drives the adjustment seat 441 to move on the adjustment guide rail 442. It should be noted that the adjustment seat 441 is provided with a through hole through which the lead screws of the lead screw pairs of the other adjustment mechanisms can pass to avoid interference.

[0028] In this embodiment, the column 421 is provided with two adjustment mechanisms, the drilling machine 31 is provided with three, and the vertical drive mechanism is also provided with three. One vertical drive mechanism located at the head end of the column 421 is fixedly installed on the column 421, and the other two vertical drive mechanisms are respectively connected to the column 421 through corresponding adjustment mechanisms. In this way, the spacing between the other two vertical drive mechanisms can be adjusted by the adjustment mechanism (that is, along the length direction of the machine base 2, one drilling machine 31 remains in the position of the column 421, and the positions of the other two drilling machines 31 on the column 421 are adjusted). By adjusting the spacing between adjacent drilling machines 31, and designing the arrangement and shape of the clearance holes 212, it is possible to meet the requirement that a single guide rail drilling machine can process ball linear guide rail workpieces with specifications of 15, 20, 25, 30, 35, 45, 55, 65, etc.

[0029] For example, the workbench 21 is provided with clearance holes 212 that match the mounting holes in various types of guide rail workpieces 1. The diameter and spacing of the mounting holes of different types of guide rail workpieces 1 are different. Specifically, the clearance holes 212 are designed according to the specific type of guide rail workpiece 1 to be processed, so that the clearance holes 212 can be matched with various different types of guide rail workpieces 1 actually processed. The spacing between adjacent drilling machines 31 along the length direction of the machine base 2 can be adjusted by the adjustment mechanism, and the spacing between all drilling machines 31 can be precisely adjusted. At the same time, the clearance holes 212 allow the drill bits of the drilling machines 31 to pass through and fit, so as to meet the needs of processing different types of guide rail workpieces 1.

[0030] For example, a plurality of reinforcing ribs 51 are connected between the movable pallet 5 and the saddle 411. The plurality of reinforcing ribs 51 are arranged at intervals along the length direction of the base 2, which can improve the support effect of the movable pallet 5, improve the effective support of the worktable 21 during the drilling process, and ensure the accuracy of the mounting hole.

[0031] For example, such as Figure 3As shown, the guide rail drilling machine also includes a pressing device 7, which includes a pressing bracket 71, a pressing roller 72, and a pressing driver 73. The pressing driver 73 is preferably a cylinder. The pressing bracket 71 is connected to the moving device 4, and the moving device 4 can drive the pressing bracket 71 to move along the length and width directions of the machine base 2. The pressing driver 73 is mounted on the pressing bracket 71, and the output end of the pressing driver 73 is rotatably connected to the pressing roller 72 and drives the pressing roller 72 along the height of the machine base 2. The direction moves vertically; after the guide rail workpiece 1 is clamped and fixed on the worktable 21 and before drilling, the pressure roller 72 on the pressure device 7 is driven by the column 421 to roll the guide rail workpiece 1 to be processed once along the length direction of the machine base 2, so as to ensure that the guide rail workpiece 1 is in a straight state during drilling and to ensure good drilling accuracy; when the pressure roller 72 rolls the guide rail workpiece 1, the pressure roller 72 is driven to press down by the pressure drive 73. After the guide rail workpiece 1 is flattened, the pressure drive 73 drives the pressure roller 72 to rise, so that the pressure roller 72 is separated from the guide rail workpiece 1.

[0032] For example, the workbench 21 includes a table surface and a clamping assembly 23. The table surface has a clamping groove 211 for placing the guide rail workpiece 1 along the length direction of the machine base 2. The bottom surface of the clamping groove 211 has multiple sets of clearance holes 212. One side of the clamping groove 211 is a fixed positioning surface. The clamping assembly 23 has multiple clamping components spaced apart along the length direction of the clamping groove 211, which can press the guide rail workpiece 1 against the fixed positioning surface. The clamping assembly 23 includes a clamping cylinder and a pressure block disposed at the output end of the clamping cylinder. The densely arranged clamping assembly 23, together with the wide-body coplanar pressure block, clamps the guide rail workpiece 1 in the clamping groove 211, so that at least one side of the guide rail workpiece 1 is supported by a plane along its entire length, effectively reducing the bending that may be caused by the torque during drilling, and well balancing the reliability of clamping and the convenience of cleaning. At the same time, through the specially designed clearance holes 212, it is possible to complete the drilling of multiple models of guide rail workpieces 1 in a single guide rail drilling machine.

[0033] For example, a chamfering device 6 is provided below the workbench 21 for chamfering the bottom of the mounting hole of the guide rail workpiece 1, and the chamfering device 6 is connected to the column 421. The chamfering device 6 can be used to chamfer the bottom of the hole after the drilling device 3 has drilled the guide rail workpiece 1, so as to realize the processing of two processes on the same equipment, reduce costs and improve processing efficiency. At the same time, the chamfering device 6 and the movable support plate 5 move synchronously along the length of the machine base 2, thereby ensuring that there is no interference between the chamfering device 6 and the movable support plate 5, and ensuring the normal operation of the guide rail drilling machine.

[0034] For example, the machine base 2 is provided with a spiral chip conveyor 8 arranged along its length. The spiral chip conveyor 8 is located below the worktable 21. The spiral chip conveyor 8 can collect and automatically discharge the chips generated by drilling and chamfering of the guide rail workpiece 1, preventing chip accumulation from reducing the processing accuracy and ensuring product processing quality, while eliminating the need for manual cleaning.

[0035] Specifically, the longitudinal drive mechanism includes a longitudinal guide rail 412 and a longitudinal driver 67. The longitudinal guide rail 412 is disposed on the base 2 along the length direction of the base 2. The longitudinal driver 67 drives the saddle 411 to move longitudinally on the longitudinal guide rail 412. Preferably, the longitudinal driver 67 includes a longitudinal motor mounted on the base 2, a gear disposed at the output end of the longitudinal motor, and a rack disposed on the longitudinal guide rail 412 and arranged along its length direction. The gear meshes with the rack. The saddle 411 slides with the base 2 through the longitudinal guide rail 412. The transverse drive mechanism includes a transverse guide rail 422 and a transverse driver 423. The transverse guide rail 422 is disposed on the saddle 411 along the width direction of the base 2. The transverse driver 423 drives the column 421 to move laterally on the transverse guide rail 422. Device 423 includes a drive handwheel and a lead screw assembly. The lead screw nut of the lead screw assembly is fixedly connected to the column 421, the lead screw of the lead screw assembly is fixedly connected to the drive handwheel, and the lead screw of the lead screw assembly is rotatably connected to the saddle 411. Rotating the drive handwheel enables the column 421 to move laterally on the saddle 411. The vertical drive mechanism includes a vertical guide rail 432 and a vertical driver 433. The vertical guide rail 432 is arranged on the column 421 along the height direction of the base 2. The vertical driver 433 drives the mounting base 431 to move vertically on the vertical guide rail 432. The vertical driver 433 includes a vertical motor and a lead screw assembly. The lead screw nut on the lead screw assembly is fixedly connected to the mounting base 431, the lead screw of the lead screw assembly is fixedly connected to the output end of the vertical motor, and the lead screw of the lead screw assembly is rotatably connected to the column 421. The vertical motor enables the mounting base 431 to move up and down along the height direction of the base 2.

[0036] For example, the workbench 21 is provided with a chip baffle 24 along the length of the base 2 on the side near the drilling device 3 to prevent flying chips generated during drilling from entering the drilling device 3 and damaging the equipment.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
