Description

Technical Field

[0001] This invention relates to the field of guide rail drilling, grinding, and assembly technology, and particularly to an integrated device for drilling and grinding guide rails. Background Technology

[0002] In the industrial field, guide rails, as the core basic components for realizing the linear motion of parts, directly determine the operational stability, positioning accuracy, and service life of the entire equipment through their machining accuracy. With the increasing demands for miniaturization, integration, and high precision in modern industry, the structural forms of guide rails are becoming increasingly complex. Among them, irregularly shaped guide rails bent at specific angles are increasingly widely used in right-angle transmission mechanisms and multi-directional feed systems because they effectively save installation space and optimize motion paths. However, the machining process of bent guide rails faces many technical bottlenecks, especially in the two key processes of drilling and grinding, where existing machining methods have significant shortcomings and cannot meet the demands of efficient and high-precision production.

[0003] On the one hand, traditional guide rail drilling processes mainly rely on CNC drilling machines or manual hand-held drilling equipment. However, when it comes to bending guide rails, due to their non-linear bending structure, the fixed worktable and linear feed path of conventional drilling machines cannot meet the drilling requirements of the bending parts. Guide rails with different bending angles require customized special fixtures and drilling tools, resulting in high equipment investment costs and making it difficult to meet the needs of multi-variety, small-batch production.

[0004] On the other hand, the surface grinding of the side and bottom surfaces in guide rail processing has the following problems: 1. Hole drilling and grinding are carried out in separate steps. The guide rail needs to be drilled on a drilling machine first, and then transferred to the grinding equipment for grinding of the side and bottom surfaces. The transfer between processes not only increases the production cycle, but also easily causes positioning errors due to secondary clamping, affecting the relative position accuracy of the hole and the grinding surface; 2. Multi-sided grinding requires repeated flipping of the guide rail. Existing grinding equipment requires manual or special flipping mechanism to flip the guide rail when grinding the bottom surface of the guide rail, which makes the whole processing process longer and the processing efficiency lower.

[0005] In summary, there is an urgent need for a specialized device that can adapt to bent guide rail structures, achieve integrated drilling and grinding, and complete side and bottom grinding without flipping, in order to meet the modern industrial demand for high-efficiency guide rail processing. Summary of the Invention

[0006] To address the above problems, this invention proposes an integrated device for drilling and grinding guide rails. The technical solution used is as follows:

[0007] An integrated device for drilling and grinding guide rails includes a support, a movable frame driven by a dual-axis moving system, a drilling device and a grinding device mounted on the movable frame, a support device mounted on the support, and a positioning device mounted on the support device.

[0008] The hole-opening device includes a lifting rod slidably mounted on a movable frame, and a drill bit rotatably mounted on the lifting rod.

[0009] The grinding device includes a second lifting rod slidably mounted on a movable frame, a rotating frame rotatably mounted on the second lifting rod, two sliding blocks slidably mounted on the rotating frame, a flipping frame rotatably mounted on the sliding blocks, and a grinding wheel rotatably mounted on the flipping frame; both sides of the flipping frame are provided with sloping push blocks.

[0010] The supporting device includes two supporting plates, a sliding adjusting block disposed between the two supporting plates and slidably mounted on the support, a rotating adjusting block slidably mounted on the supporting plates and rotatably mounted on the sliding adjusting block, and a clamping device;

[0011] The positioning devices are arranged in pairs; each positioning device includes an L-shaped positioning rod that is slidably and elastically mounted on a support plate, an opening and closing frame consisting of a top plate and a bottom plate that are slidably and elastically connected together, a push rod that is slidably mounted on the top plate of the opening and closing frame, and a rotating support block mounted on the L-shaped positioning rod; several connecting blocks are slidably and elastically mounted on the L-shaped positioning rod, and the rotating support block is rotatably mounted on the connecting blocks; the top plate of the opening and closing frame is fixedly mounted on the L-shaped positioning rod, and a wedge block is fixedly mounted on the bottom plate, with a wedge groove on the push rod corresponding to the wedge block; a limiting plate is slidably and elastically mounted on the rotating support block, with a slot on the limiting plate, and a slotted plate is fixedly mounted on the bottom plate of the opening and closing frame corresponding to the slot.

[0012] Furthermore, the clamping device includes two clamping blocks disposed on both sides of the rotating adjusting block and slidably mounted on the support, a lifting block slidably and elastically mounted on the support, an arc-shaped block fixedly mounted on the lifting block, and an adjusting rod rotatably mounted on the support; the opposing surfaces of the clamping block and the lifting block are inclined surfaces that fit together; a protruding rod that intermittently pushes the arc-shaped block to move is fixedly mounted on the adjusting rod.

[0013] Furthermore, a through-hole block is slidably installed on the support plate, and the support device also includes a clamping rod that passes through the through hole of the through-hole block and is rotatably installed on the support; a second protrusion is fixedly installed on the clamping rod to intermittently squeeze the through-hole block from the inside of the through-hole block.

[0014] Furthermore, the surfaces of the card plate and the limiting plate opposite each other are set as inclined surfaces.

[0015] Furthermore, the support plate is provided with protrusions corresponding to the positioning device.

[0016] Furthermore, the opening device also includes a dust cover that is slidably and elastically mounted on a movable frame.

[0017] Furthermore, the polishing device also includes a dust suction hood two that is fixedly mounted on the flipping frame.

[0018] Furthermore, the polishing device also includes a camera fixedly mounted on a flipping frame.

[0019] Furthermore, a plurality of ball bearings are installed on the bottom surface of the support plate, and the rolling mounting seats of the ball bearings are slidably and elastically mounted on the bottom surface of the support plate.

[0020] Because the present invention adopts the above-described technical solution, the present invention has the following advantages:

[0021] 1. This invention addresses the problem of repeated flipping required for grinding the side and bottom surfaces of guide rails by using a coordinated design of a moving frame, a hole-making device, a grinding device, a support device, and a positioning device. It integrates the traditionally separate steps of "hole making," "top surface grinding," and "side and bottom surface grinding" into a single processing platform. This eliminates the need for inter-process transfer of the guide rail and flipping operations, allowing the grinding of the side and bottom surfaces to be completed in a single clamping state, significantly improving processing efficiency and shortening the production cycle.

[0022] 2. Through integrated design, the present invention enables the guide rail to be clamped and positioned only once during the entire processing, eliminating the error caused by secondary clamping. Furthermore, an adjustable support device is set up to address the non-linear structural characteristics of the bent guide rail, eliminating the need to customize special fixtures for guide rails with different bending angles. It can quickly adapt to the processing needs of irregular guide rails with different bending angles and specifications without requiring large-scale adjustments to the equipment or replacement of tooling.

[0050] Example:

[0051] An integrated device for drilling and grinding guide rails, such as Figures 1-2 As shown, it includes a support 1, a dual-axis moving system 2, a moving frame 3, an opening device 4, a grinding device 5, a supporting device 6, and a positioning device 7; the dual-axis moving system 2 is used to drive the moving frame 3 to move along the X-axis and Y-axis, and can adopt existing technical means; the opening device 4 and the grinding device 5 are installed on the moving frame 3; the supporting device 6 is installed on the support 1, and the positioning device 7 is installed on the supporting device 6.

[0052] like Figures 3-4 As shown, the hole-opening device 4 includes a drill bit 401, a lifting rod 402, a hole-opening motor 403, and a dust-collecting hood 407. The lifting rod 402 is vertically slidably mounted on the movable frame 3, the drill bit 401 is rotatably mounted on the lifting rod 402, the hole-opening motor 403 is fixedly mounted on the lifting rod 402 and its output end is coaxially fixedly connected to the drill bit 401, and the dust-collecting hood 407 is vertically slidably mounted on the movable frame 3 by a compression spring. The drill bit 401 intermittently passes through the dust-collecting hood 407.

[0053] A rack 405 is fixedly installed on the lifting rod 402, and a gear 406 that meshes with the rack 405 is rotatably installed on the moving frame 3, and a lifting motor 404 whose output end is coaxially and fixedly connected to the gear 406 is also fixedly installed.

[0054] like Figure 3 and Figures 5-7 As shown, the polishing device 5 includes a second lifting rod 501, a rotating frame 505, a bidirectional lead screw 506, a sliding block 507, a tilting frame 509, a polishing wheel 510, a second dust collection hood 512, and a camera 516. The second lifting rod 501 is vertically slidably mounted on the movable frame 3, and the rotating frame 505 is rotatably mounted on the second lifting rod 501. The bidirectional lead screw 506 is rotatably mounted on the rotating frame 505 and is driven to rotate by a motor mounted on the rotating frame 505. Two sliding blocks 507 are symmetrically mounted on the bidirectional lead screw 506 and slidably mounted on the rotating frame 505. Each sliding block 507 is rotatably mounted with a tilting frame 509.

[0055] A flipping shaft 5091 is fixedly installed on the flipping frame 509. The flipping shaft 5091 is rotatably mounted on the sliding block 507 and is coaxially fixedly connected to the output end of the flipping motor 508 fixedly mounted on the sliding block 507. A grinding wheel 510 is rotatably mounted on the flipping frame 509 and is coaxially fixedly connected to the output end of the grinding motor 511 fixedly mounted on the flipping frame 509. A second dust collection hood 512 is fixedly mounted on the flipping frame 509. Several cameras 516 are provided and fixedly mounted on the flipping frame 509. This embodiment uses two sets of cameras 516 on each flipping frame 509 as an example for explanation. Both sides of the flipping frame 509 are provided with sloping push blocks 5092.

[0056] A rack 2 503 is fixedly installed on the lifting rod 2 501, and a gear 2 504 that meshes with the rack 2 503 is rotatably installed on the moving frame 3, and a lifting motor 2 502 whose output end is coaxially and fixedly connected to the gear 2 504 is also fixedly installed.

[0057] An output gear 515 is coaxially fixedly mounted on the rotating shaft of the rotating frame 505; an input gear 514 that meshes with the output gear 515 is rotatably mounted on the lifting rod 501, and a rotary motor 513 whose output end is coaxially fixedly connected to the input gear 514 is also fixedly mounted.

[0058] In this embodiment, both the first dust hood 407 and the second dust hood 512 are connected to an external negative pressure vacuum cleaner, so that the fine debris generated during polishing is sucked away in time.

[0059] The camera 516 uses an industrial camera that integrates image acquisition and position sensing functions.

[0060] like Figures 8-14 As shown, the supporting device 6 includes a supporting plate 601, a rotating adjusting block 602, a sliding adjusting block 603, a sliding bushing 604, an adjusting rod 605, an arc-shaped block 606, a lifting block 607, a pressing block 608, and a pressing rod 609. Two supporting plates 601 are provided. The sliding adjusting block 603 is disposed between the two supporting plates 601 and slidably mounted on the support 1. Each supporting plate 601 has a vertically slidably mounted rotating adjusting block 602 rotatably mounted on the sliding adjusting block 603. The adjusting rod 605 is rotatably mounted on the support 1, and a sliding sleeve 604 is provided on the rod body to guide the sliding adjusting block 603. Several ball bearings 6013 are mounted on the bottom surface of the supporting plate 601, and the rolling mounting seats of the ball bearings 6013 are slidably and elastically mounted on the bottom surface of the supporting plate 601.

[0061] Each rotating adjustment block 602 is provided with two clamping blocks 608. The two clamping blocks 608 are placed on both sides of the rotating adjustment block 602 and are horizontally slidably mounted on the support 1. Each clamping block 608 corresponds to a vertically sliding and elastically mounted lifting block 607 on the support 1. The opposing surfaces of the clamping block 608 and the lifting block 607 are inclined surfaces that fit together. When the lifting block 607 moves downward, it can push the clamping block 608 to move towards the rotating adjustment block 602. The two clamping blocks 608 clamp the rotating adjustment block 602, and the rotating adjustment block 602 stops rotating. An arc surface block 606 is fixedly installed on the lifting block 607, and a protruding rod 6051 is fixedly installed on the adjusting rod 605. When the adjusting rod 605 rotates, the protruding rod 6051 moves along the arc surface of the arc surface block 606, thereby pressing the arc surface block 606 down and driving the lifting block 607 to move down.

[0062] A through-hole block 6011 is slidably installed on the support plate 601. A clamping rod 609 passes through the through hole of the through-hole block 6011 and is rotatably installed on the support 1. A second protruding rod 6091 is fixedly installed on the clamping rod 609. When the clamping rod 609 is rotated, the second protruding rod 6091 squeezes the through-hole block 6011 from inside the through-hole block 6011, thereby achieving the effect of fixing the support plate 601.

[0063] like Figure 9 and Figures 15-20 As shown, the positioning device 7 includes an L-shaped positioning rod 701, a push cylinder 702, a push rod 703, an opening and closing frame 704, and a rotating support block 705; the positioning devices 7 are arranged in pairs, and several pairs of positioning devices 7 are evenly provided on each support plate 601; the L-shaped positioning rod 701 includes a horizontal rod and a vertical rod, the horizontal rod is horizontally slidably installed on the support plate 601 and elastically connected to the support plate 601 through a tension spring, the vertical rod of the same pair of L-shaped positioning rods 701 clamps and positions the guide rail placed on the support plate 601, and the top of the vertical rod is inclined;

[0064] The opening and closing frame 704 consists of a top plate and a bottom plate that slide vertically and are elastically connected by a tension spring. The top plate is fixedly mounted on a horizontal bar of an L-shaped support rod 701. A push rod 703 is horizontally slidably mounted on the top plate. Several wedge blocks 7041 are fixedly mounted on the bottom plate. The push rod 703 has a wedge groove 7031 corresponding to the wedge block 7041. The push rod 703 is driven to move by a push cylinder 702. The push cylinder 702 can be an electric cylinder. The cylinder body is fixedly mounted on an L-shaped positioning rod 701, and the output end is fixedly connected to the push rod 703. When the wedge block 7041 enters the wedge groove 7031, the top plate and the bottom plate of the opening and closing frame 704 move closer to each other. When the wedge block 7041 moves outward along the wedge groove 7031, the top plate and the bottom plate of the opening and closing frame 704 move further apart.

[0065] Several rotating support blocks 705 are installed on the horizontal bar of the L-shaped positioning rod 701. Several connecting blocks are vertically sliding on the horizontal bar of the L-shaped positioning rod 701 and elastically installed through a tension spring. The rotating support blocks 705 are rotatably installed on the connecting blocks through a rotating shaft. A limit plate 7051 is slidably and elastically installed on the rotating support block 705. The limit plate 7051 is provided with a slot. A card plate 7042 is fixedly installed on the bottom plate of the opening and closing frame 704 corresponding to the slot. When the card plate 7042 moves downward and extends into the slot, the top surface of the rotating support block 705 contacts the bottom plate of the opening and closing frame 704. The opening and closing frame 704 continues to move downward under the action of the push rod 703, so that the rotating support block 705 moves downward until the bottom surface abuts against the support 1. The rotating support block 705 remains vertically fixed and supports the L-shaped positioning rod 701.

[0066] like Figure 14As shown, the support plate 601 has a protrusion 6012 corresponding to the positioning device 7. When the rotating support block 705 passes the protrusion 6012, it will move as follows: Figure 19 Rotate to horizontal as shown; the surfaces of the clamping plate 7042 and the limiting plate 7051 opposite each other are set as inclined surfaces, for example... Figure 19 When the rotating support block 705 in the horizontal state shown moves downward, the locking plate 7042 will push the limiting plate 7051 to move, and the movement will not be interfered with by the limiting plate 7051.

[0067] This embodiment also includes a control terminal (not shown in the figure) with a control panel, used to control the operation of various electrical components.

[0068] The working principle of this embodiment is as follows:

[0069] 1. Adjusting the support device 6 according to the shape of the guide rail: In the initial state, the two support plates 601 are collinear; if the guide rail to be processed is straight, there is no need to adjust the support device 6, and it can be placed directly on the support plate 601; if the guide rail to be processed is a bent irregular shape, it is necessary to manually move the sliding adjustment block 603, rotate the adjustment block 602 to rotate, and the through hole block 6011 slides relative to the support plate 601 so that the included angle between the two support plates 601 corresponds to the bending angle of the guide rail. Then, rotate the adjustment rod 605 and the clamping rod 609 to fix the support plate 601, and then place the irregular guide rail on the support plate 601. Figure 23 As shown.

[0070] 2. Positioning the guide rail: When the guide rail is placed on the support plate 601, the guide rail pushes open the paired L-shaped positioning rods 701. The vertical rods of the L-shaped positioning rods 701 are close to the side of the guide rail. During the pushing process, the rotating support block 705 on the L-shaped positioning rod 701 is still suspended. After the guide rail falls on the support plate 601, the support plate 601 moves down, and the rotating support block 705 moves down but is still suspended. Then, the push cylinder 702 is activated, the push rod 703 moves, the wedge block 7041 moves out of the wedge groove 7031, the clamping plate 7042 moves down and inserts into the clamping groove of the limiting plate 7051. Then, the opening and closing frame 704 continues to move down, so that the rotating support block 705 is fixedly supported on the plane of the support 1, fixing the L-shaped positioning rod 701, and the positioning is completed.

[0071] 3. Drilling and grinding the top surface of the guide rail: First, the dual-axis moving system 2 drives the moving frame 3 to move from front to back once, and the camera 516 captures the shape of the guide rail; then, the dual-axis moving system 2 drives the moving frame 3 to move along the guide rail to perform drilling and grinding; the drilling motor 403 drives the drill bit 401 to rotate, and the lifting motor 404 drives the drill bit 401 to rise and fall to perform drilling work; the grinding motor 511 drives the grinding wheel 510 to rotate. If it is an irregularly shaped guide rail, the rotary motor 513 drives the rotary frame 505 to rotate. Under the drive of the dual-axis moving system 2, the grinding wheel 510 moves along the top surface of the guide rail to perform grinding work.

[0072] IV. Drilling and grinding the sides and bottom of the guide rail: The bidirectional lead screw 506 drives the two sliding blocks 507 to move away from each other, the tilting motor 508 drives the tilting frame 509 to rotate 90°, the lifting rod 501 moves downward, the two tilting frames 509 are placed on both sides of the guide rail, the bidirectional lead screw 506 drives the two sliding blocks 507 to move closer to each other, and with the assistance of the camera 516, the grinding wheel 510 contacts the side of the guide rail; then the grinding wheel 510 moves along the side of the guide rail, as... Figure 21 As shown, proceed with the grinding process; after grinding the sides of the guide rail, readjust the position of the grinding wheel 510, as shown. Figure 22 As shown, the grinding wheel 510 contacts the bottom surface of the guide rail, and then moves along the bottom surface of the guide rail to perform grinding work. If it is an irregularly shaped guide rail with a small corner (such as less than 150°), when the grinding wheel 510 grinds close to the corner, the bidirectional lead screw 506 drives the two sliding blocks 507 to move away from each other. Then, the rotary motor 513 drives the rotary frame 505 to rotate at the same angle as the corner, so that the two grinding wheels 510 are aligned with the other end of the irregularly shaped guide rail again. After that, the bidirectional lead screw 506 drives the two sliding blocks 507 to move closer to each other. With the assistance of the camera 516, the grinding wheel 510 contacts the side of the guide rail and continues to work. The unfinished parts at the corner are manually ground.

[0073] When grinding the side and bottom surfaces of the guide rail, the grinding wheel 510 moves along the guide rail. When the control terminal detects that the sloped push block 5092 is about to approach the L-shaped positioning rod 701, the control terminal activates the push cylinder 702 on the L-shaped positioning rod 701. The push rod 703 moves in the opposite direction, and the rotating support block 705 is no longer fixed. The vertical rod of the L-shaped positioning rod 701 will move along the sloped push block 5092 when the flipping frame 509 approaches. After the sloped push block 5092 passes, the L-shaped positioning rod 701 rebounds. Then the control terminal activates the push cylinder 702 on the L-shaped positioning rod 701 again. The push rod 703 moves in the forward direction to fix the rotating support block 705 on the plane of the support 1, thereby preventing the vertical rod of the L-shaped positioning rod 701 from affecting the movement of the grinding wheel 510.
