Description

Technical Field

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

[0002] Linear guide rails are components used to support and guide motion, primarily in applications requiring high precision or high-speed linear reciprocating motion. During their production, drilling is necessary. For long-stroke linear guide rails, multiple evenly spaced holes need to be machined along the direction of motion. In existing technologies, drilling operations on linear guide rails typically require drilling equipment. The linear guide rail workpiece is placed on a drilling platform, held and positioned by a fixture, and the drilling mechanism moves along the length of the workpiece to perform the drilling operation. For example, the invention patent CN208391492U discloses a drilling device for linear guide rail workpieces, including a base with a fixed worktable mounted on it. A fixture for fixing the linear guide rail workpiece is mounted on the worktable. A support frame on the support platform has several linear slides, and a drilling mechanism is mounted on each slide. The distance between the linear slides can be adjusted according to processing needs, thereby adjusting the hole spacing.

[0003] In practical use, the linear guide workpiece is fixed on the drilling platform and then clamped and fixed by a fixture to ensure that its position remains unchanged. The drilling mechanism moves along the length of the linear guide workpiece to drill holes in the workpiece. Especially for long-stroke linear guide workpieces, the required hole spacing on the machining surface at different positions is different. During each drilling process, the position of the drilling mechanism needs to be frequently adjusted, and even additional drilling mechanisms need to be installed and removed. The installation positions on the linear slide are limited, and most of them are fixed by bolts, which is inconvenient to use and easy to be misoperated by non-professionals. Summary of the Invention

[0004] The purpose of this invention is to design a guide rail drilling processing device to overcome the shortcomings of the above-mentioned technology. The drilling head is easy to install, remove, and adjust on the drilling mounting plate, and has good applicability. It also prevents the risk of misoperation by non-professionals.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a guide rail drilling processing device, comprising:

[0006] A worktable is provided with a placement platform that extends along its length. The placement platform is provided with a plurality of clamping mechanisms that are spaced apart along its length. The linear guide rail workpiece is placed laterally on the placement platform and clamped and fixed by each of the clamping mechanisms. The placement platform is provided with a plurality of machining holes that are spaced apart along its length. Each of the machining holes corresponds to the surface of the linear guide rail workpiece to be machined.

[0007] A workpiece translation device, wherein the translation end of the workpiece translation device is connected to the placement table, and the workpiece translation device adjusts the position of the placement table in the lateral direction to drive the linear guide workpiece to translate along its length direction.

[0008] A plurality of telescopic drilling mechanisms are provided. Several mounting positions are distributed on both sides of the worktable relative to the placement table. Each telescopic drilling mechanism is located on one of the mounting positions. Two telescopic drilling mechanisms on both sides of the placement table are correspondingly arranged. Each telescopic drilling mechanism includes a drilling translation device, a drilling mounting plate, and two drilling heads arranged side by side and spaced apart. The translation end of the drilling translation device is connected to the drilling mounting plate. The drilling heads are detachably connected to the drilling mounting plate. The drilling translation device adjusts the position of the drilling heads in the longitudinal direction.

[0009] The drilling head is surrounded by a square array of several elastic telescopic rods. These rods are elastically telescopic relative to the drilling head and tend to move upwards. An operating plate is fixedly connected to the upper end of each elastic telescopic rod, and a handle is provided on the operating plate. An adjustment groove extending laterally is provided on the drilling mounting plate, penetrating both side walls of the plate. The lower end of each elastic telescopic rod is T-shaped, extending to the bottom surface of the drilling head and sliding within the adjustment groove. The inner wall of the adjustment groove has several locking holes spaced apart along its length. A locking pin is provided at the lower end of each elastic telescopic rod, engaging with the locking holes. A downward movement space is reserved between the lower inner wall of the adjustment groove and the lower end of the elastic telescopic rod.

[0010] Preferably, the elastic telescopic rod includes a locking rod and an elastic element. The drilling head has a first movable hole and a second movable hole arranged coaxially and vertically relative to the elastic telescopic rod. The upper end of the locking rod is slidably disposed on the inner wall of the first movable hole, and the lower end of the locking rod is slidably disposed on the inner wall of the second movable hole. The drilling head has an installation cavity between the first movable hole and the second movable hole, and both the first movable hole and the second movable hole are interconnected with the installation cavity. An installation ring is fixedly connected to the outer wall of the locking rod. The elastic element is disposed between the installation ring and the installation cavity. The portion of the lower end of the locking rod that passes through the second movable hole is the lower end of the elastic telescopic rod.

[0011] Preferably, a protective sleeve is provided inside the mounting cavity, and the mounting ring is slidably disposed within the protective sleeve.

[0012] Preferably, the lower end of the elastic telescopic rod includes a coaxial guide rod and a limiting ring arranged vertically. The adjusting groove includes a stroke groove and a limiting groove. The guide rod is slidably disposed in the stroke groove, and the limiting ring is slidably disposed in the limiting groove. The locking pin is fixedly connected to the top surface of the limiting ring. The spacing of the limiting grooves is greater than the thickness of the limiting ring. The bottom surface of the limiting ring and the lower inner wall of the limiting groove are clearance-fitted to form the downward movement space.

[0013] Preferably, there are two locking pins, which are symmetrically arranged on the top surface of the limiting ring. The locking holes are divided into two groups, which are symmetrically arranged and correspond to the two locking pins respectively.

[0014] Preferably, the limiting ring is disposed at the lower end of the guide rod, and the bottom surface of the limiting ring cooperates with the bottom surface of the guide rod.

[0015] Preferably, a rolling element is rotatably disposed at the center of the bottom surface of the limiting ring, and a translation groove is formed on the lower inner wall of the limiting groove. The translation groove is interconnected with the lower displacement space, and the portion of the rolling element extending out of the bottom surface of the limiting ring slides in cooperation with the translation groove.

[0016] Preferably, the workpiece translation device is an electric lead screw, and a first nut seat is provided on the side of the placement platform near the workpiece translation device, and the first nut seat is threadedly connected to the lead screw of the workpiece translation device.

[0017] Preferably, the drilling translation device is an electric lead screw, and the drilling mounting plate is provided with a second nut seat, which is threadedly connected to the lead screw of the drilling translation device.

[0018] Preferably, a receiving groove extending along the length of the worktable is provided through the worktable below the workpiece translation device, and guide grooves extending along the length of the worktable are provided on both sides of the worktable relative to the placement table. The guide grooves and the receiving grooves are identical, and a plurality of partitions are provided on the inner wall of the guide grooves at intervals along the length of the worktable.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The lateral position of each telescopic drilling mechanism is fixed on the worktable. The distance between the two drilling heads of the telescopic drilling mechanism can be adjusted according to the required hole spacing of the corresponding position of the linear guide workpiece. Thus, telescopic drilling mechanisms capable of processing different hole spacings are pre-set. When using this processing device, the workpiece translation device drives the placement table to translate, so that the working surfaces of the linear guide workpiece, which is placed laterally on the placement table and clamped by each clamping mechanism, correspond to each telescopic drilling mechanism. The drilling translation device of each telescopic drilling mechanism drives the drilling mounting plate to approach the placement table, so that the processing end of the drilling head passes through the processing hole to drill the linear guide workpiece. This makes the drilling processing device more versatile.

[0021] 2. Several elastic telescopic rods are arranged around the drilling head. These rods work together to move the operating plate upwards, away from the drilling head. As the lower end of each rod moves upwards, the locking pin engages with the corresponding locking hole on the inner wall of the adjustment groove, thus locking the drilling head on the drilling mounting plate. When assembling, disassembling, or adjusting the position of the drilling head laterally on the telescopic drilling mechanism, the operator simply holds the handle and presses down on the operating plate to move the corresponding elastic telescopic rods downwards. This causes the locking pins to move downwards with each rod and completely disengage from their respective locking holes, unlocking the drilling head. After unlocking, the operator continues to press down on the operating plate while simultaneously moving the drilling head along the length of the adjustment groove until it reaches the predetermined position, where each locking pin aligns with its respective locking hole. In one operation, the operator releases the handle, causing each elastic telescopic rod to move upward and reset, thus achieving self-locking of the drilling head after lateral adjustment. Alternatively, after the drilling head is unlocked, the operator maintains pressure on the operating plate while moving the drilling head along the length of the adjustment slot until the lower ends of each elastic telescopic rod on the drilling head are completely disengaged from the adjustment slots on the side wall of the drilling mounting plate. At this point, the operator can use the handle to move the drilling head. Similarly, when installing the drilling head, the operator can press down on the operating plate to move it downward relative to the drilling head, thereby aligning the lower ends of each elastic telescopic rod with the adjustment slots on the side wall of the drilling mounting plate, thus completing the assembly of the drilling head on the drilling mounting plate. The disassembly, assembly, and position adjustment of the drilling head on the drilling mounting plate are relatively convenient and also prevent the risk of misoperation by non-professionals.

Several processing holes 103 are arranged through the placement platform 101 at intervals along its length. Several clamping mechanisms 102 are arranged at intervals along its length on the placement platform 101. The clamping mechanism 102 can refer to the clamping mechanism 102 disclosed in CN119794863A. The guide rail transport mechanism 4 can refer to the lifting transport mechanism disclosed in CN119794863A.

The linear guide rail workpiece 9 is placed laterally on the placement platform 101 and clamped and fixed by each clamping mechanism 102, so that each processing hole 103 corresponds to the surface to be processed of the linear guide rail workpiece 9.

[0032] The translation end of the workpiece translation device 2 is connected to the placement table 101. The workpiece translation device 2 is an electric lead screw. A first nut seat 105 is provided on the side of the placement table 101 near the workpiece translation device 2. The first nut seat 105 is threadedly connected to the lead screw of the workpiece translation device 2. The workpiece translation device 2 adjusts the position of the placement table 101 in the lateral direction to drive the linear guide workpiece 9 to translate along its length.

[0033] A receiving trough 106 extending along the length of the worktable 1 is provided through the worktable 1 below the workpiece translation device 2. A guiding trough 107 extending along the length of the worktable 1 is provided on both sides of the worktable 1 relative to the placement table 101. The guiding trough 107 and the receiving trough 106 are identical to each other, and a number of partitions 108 are provided on the inner wall of the guiding trough 107 at intervals along the length of the worktable 1.

[0034] refer to Figure 1 , Figure 3 , Figure 4 Several mounting positions 104 are distributed on both sides of the workbench 1 relative to the placement table 101. Each telescopic drilling mechanism 3 is located on each mounting position 104, and the two telescopic drilling mechanisms 3 on both sides of the placement table 101 are correspondingly arranged. The telescopic drilling mechanism 3 includes a drilling translation device 31, a drilling mounting plate 32, and two drilling heads 33 arranged side by side and spaced apart. The mounting position 104 is a plate-shaped structure. A linear slide rail extending longitudinally is provided between the drilling mounting plate 32 and the mounting position 104. The drilling translation device 31 is fixedly connected to the mounting position 104. The translation end of the drilling translation device 31 is connected to the drilling mounting plate 32. The drilling translation device 31 is an electric lead screw. The drilling mounting plate 32 is provided with a second nut seat 301. The second nut seat 301 is threadedly connected to the lead screw of the drilling translation device 31. The drilling heads 33 are detachably connected to the drilling mounting plate 32. The drilling translation device 31 adjusts the position of the drilling heads 33 longitudinally.

[0035] refer to Figures 4 to 7 The drilling head 33 is surrounded by a square array of several elastic telescopic rods 5. Preferably, the drilling head 33 has four elastic telescopic rods 5. Each elastic telescopic rod 5 includes a locking rod 51 and an elastic element 52. The drilling head 33 has a first movable hole 302 and a second movable hole 303 arranged coaxially and vertically relative to the elastic telescopic rods 5. The upper end of the locking rod 51 is slidably disposed on the inner wall of the first movable hole 302, and the lower end of the locking rod 51 is slidably disposed on the inner wall of the second movable hole 303. The first movable hole 302 is a stepped hole, and the upper end of the locking rod 51 is a stepped end.

[0036] A mounting cavity 304 is provided between the drilling head 33 and the first movable hole 302 and the second movable hole 303. Both the first movable hole 302 and the second movable hole 303 are connected to the mounting cavity 304. A mounting ring 505 is fixedly connected to the outer wall of the locking rod 51. The elastic element 52 can be a spring structure. The elastic element 52 is disposed between the mounting ring 505 and the mounting cavity 304, so that the elastic telescopic rod 5 is elastically telescopic relative to the drilling head 33 and has an upward tendency to move horizontally. The lower end of the locking rod 51 passing through the second movable hole 303 is the lower end of the elastic telescopic rod 5, and the upper end of the locking rod 51 passing through the first movable hole 302 is the upper end of the elastic telescopic rod 5.

[0037] Preferably, a protective sleeve 305 is provided inside the mounting cavity 304, and the mounting ring 505 is slidably disposed inside the protective sleeve 305, which protects the elastic element 52.

[0038] The lower end of the elastic telescopic rod 5 extends to the bottom surface of the drilling head 33 and is slidably disposed within the adjustment groove 7. The lower end of the elastic telescopic rod 5 includes a coaxial guide rod 502 and a limiting ring 503 arranged vertically. The limiting ring 503 is disposed at the lower end of the guide rod 502, and the bottom surface of the limiting ring 503 cooperates with the bottom surface of the guide rod 502. An operating plate 6 is fixedly connected to the upper end of each elastic telescopic rod 5 of the drilling head 33, and a handle 601 is provided on the operating plate 6.

[0039] The drilling mounting plate 32 has an adjustment groove 7 extending laterally. The adjustment groove 7 penetrates both sides of the drilling mounting plate 32. The adjustment groove 7 includes a stroke groove 71 and a limit groove 72. The guide rod 502 is slidably disposed in the stroke groove 71, and the limit ring 503 is slidably disposed in the limit groove 72.

[0040] Two symmetrically arranged locking pins 501 are fixedly connected to the top surface of the limiting ring 503. The spacing of the limiting grooves 72 is greater than the thickness of the limiting ring 503. A plurality of locking holes 701 are spaced apart along the length of the upper inner wall of the limiting groove 72. These locking holes 701 are divided into two groups, which are symmetrically arranged and correspond to the two locking pins 501 respectively. The bottom surface of the limiting ring 503 and the lower inner wall of the limiting groove 72 are fitted together to form a downward movement space 8. A rolling element 504, which can be a steel ball or a roller, is rolled at the center of the bottom surface of the limiting ring 503. A translation groove 702 is formed on the bottom inner wall of the limiting groove 72, and the portion of the rolling element 504 extending beyond the bottom surface of the limiting ring 503 slides in conjunction with the translation groove 702.

[0041] The lateral position of each telescopic drilling mechanism 3 is fixed on the worktable 1. The distance between the two drilling heads 33 of the telescopic drilling mechanism 3 can be adjusted according to the required hole spacing of the corresponding position of the linear guide workpiece 9. Thus, telescopic drilling mechanisms 3 capable of processing different hole spacings are pre-set. When using this processing device, the workpiece translation device 2 drives the placement table 101 to translate, so that the working surfaces of the linear guide workpiece 9, which is placed laterally on the placement table 101 and clamped and fixed by each clamping mechanism 102, correspond to each telescopic drilling mechanism 3. The drilling translation device 31 of each telescopic drilling mechanism 3 drives the drilling mounting plate 32 to approach the placement table 101, so that the processing end of the drilling head 33 passes through the processing hole 103 to perform drilling operations on the linear guide workpiece 9, making the drilling processing device more applicable.

[0042] refer to Figures 1 to 7 Several elastic telescopic rods 5 are arranged around the drilling head 33. These rods work together to move the operating plate 6 upwards, away from the drilling head 33. As the lower end of each elastic telescopic rod 5 moves upwards, the locking pin 501 engages with the corresponding locking hole 701 on the inner wall of the adjusting groove 7, thus locking the drilling head 33 in position on the drilling mounting plate 32. When assembling, disassembling, or adjusting the position of the drilling head 33 laterally on the telescopic drilling mechanism 3, the operator only needs to hold the handle 601 and press down on the operating plate 6 to move the corresponding elastic telescopic rods 5 downwards. This causes each locking pin 501 to move downwards with each elastic telescopic rod 5 and completely disengage from its locking hole 701, thereby unlocking the drilling head 33. After the drilling head 33 is unlocked, the operator continues to press down on the operating plate 6 while simultaneously moving the drilling head 33 along the length of the adjusting groove 7 until the drilling head 33 reaches the predetermined position, at which point each locking pin 501 engages with its corresponding locking hole 701. Corresponding to the locking hole 701, the operator releases the handle, causing each elastic telescopic rod 5 to move upward and reset, thus achieving self-locking of the drilling head 33 after its lateral adjustment. Alternatively, after the drilling head 33 is unlocked, the operator maintains the downward pressure on the operating plate 6 while moving the drilling head 33 along the length of the adjustment groove 7 until the lower ends of each elastic telescopic rod 5 on the drilling head 33 are completely disengaged from the adjustment grooves 7 on the side wall of the drilling mounting plate 32. At this point, the operator holds the handle to move the drilling head 33. Similarly, when installing the drilling head 33, the operator can press down the operating plate 6 to move it downward relative to the drilling head 33, thereby aligning the lower ends of each elastic telescopic rod 5 with the adjustment grooves 7 on the side wall of the drilling mounting plate 32, thus completing the assembly operation of the drilling head 33 on the drilling mounting plate 32. The disassembly, assembly, and position adjustment operations of the drilling head 33 on the drilling mounting plate 32 are relatively convenient and also prevent the risk of misoperation by non-professionals.

[0043] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
