Abstract
Description
Technical Field
[0001] This application relates to the field of drilling technology, and particularly to a vertical drilling machine. Background Technology
[0002] Some guide rails require drilling along their length (the direction of the rail's extension) for installation and positioning, especially with uniformly spaced holes. Existing drilling machine tools for guide rails generally consist of a bed, spindle, worktable, and fixture. In these machines, the bed and worktable are typically placed horizontally, and the guide rail to be drilled is horizontally mounted to the worktable using a fixture. After the guide rail is mounted to the worktable, the drilling operation can be performed by horizontally moving either the spindle or the worktable.
[0003] The existing drilling machines used for drilling guideways have the following disadvantages: 1. Because the guideways need to be placed horizontally for drilling, the guideways and machine tools occupy a large area and have low space utilization. 2. When drilling, the guideways need to move along their extension direction, and high drilling accuracy depends on the high movement accuracy of the spindle or worktable. Furthermore, cumulative errors occur during the movement of the spindle or worktable, further affecting drilling accuracy. At the same time, the large footprint and high machining accuracy requirements increase the manufacturing difficulty and production cost of the equipment. Based on the current state of the technology, there is an urgent need to provide a new type of drilling machine suitable for drilling guideways to improve at least one of the aforementioned problems of the existing technology.

[0060] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.
[0061] In this application, "transmission connection" refers to a connection between two components that can transmit torque, including direct or indirect connection between the two components.
[0062] This application provides a vertical drilling machine (hereinafter, sometimes simply referred to as a "drilling machine") suitable for machining elongated structural parts such as guide rails 100. Figure 1 As shown, a vertical drilling machine may include a first spindle 11, a second spindle 12, a first motor group 21, a second motor group 22, a base 30, and a positioning mechanism.
[0063] The preferred vertical drilling machine is a vertical two-way drilling machine, which means that it can drill holes in the workpiece from two opposite directions.
[0064] Specifically, the first spindle 11 and the second spindle 12 can be arranged opposite each other, and their axial directions can be parallel. Preferably, the axial directions of the first spindle 11 and the second spindle 12 can coincide, and their outer ends connected to the drill bit can be opposite each other. In other possible embodiments, the first spindle 11 and the second spindle 12 can also be offset in the height direction (in particular, offset from the holes of one or more positioning mechanisms described later). The workpiece such as the guide rail 100 to be drilled can be vertically arranged (the length extension direction of the slender workpiece such as the guide rail is placed in the vertical direction) between the first spindle 11 and the second spindle 12, that is, the first spindle 11 and the second spindle 12 can extend in the horizontal direction. The outer ends of the first spindle 11 and the second spindle 12 (the ends facing the guide rail or other workpieces) can be fitted with drill bits of the same diameter or different diameters according to actual processing needs. During drilling, the first spindle 11 and / or the second spindle 12 can both move toward the workpiece to drill the workpiece simultaneously or sequentially. It is understood that the vertical drilling machine of this application can also perform single-sided drilling operations on the workpiece according to actual processing needs.
[0065] For example, such as Figure 3 As shown, when the drilling pattern of the guide rail 100 is a stepped hole, the first spindle 11 and the second spindle 12 can be connected to drill bits of different diameters respectively, and drilling operations can be performed on both sides of the guide rail 100 in turn.
[0066] like Figure 1 and Figure 2 As shown, the first motor group 21 can be connected to the first spindle 11, and the second motor group 22 can be connected to the second spindle 12. Drilling operations can be performed by driving the spindle and the connected drill bit to rotate and move via the motors. Specifically, both the first motor group 21 and the second motor group 22 can include a rotary motor and a feed motor (i.e., the first motor group 21 can include a first rotary motor 211 and a first feed motor 212, and the second motor group 22 can include a second rotary motor 221 and a second feed motor 222). Both the rotary motor and the feed motor can be driven and connected to the corresponding spindle. The rotary motor driven and connected to the spindle can drive the spindle to rotate; the transmission form between the rotary motor and the spindle can be gear drive, belt drive, etc. The feed motor driven and connected to the spindle can drive the spindle to move horizontally; the transmission form between the feed motor and the spindle can be lead screw drive, etc. Preferably, the feed motor can be a servo motor to improve the accuracy of feed control.
[0067] It is understandable that the first motor group 21 and the second motor group 22 may each include only one motor for driving the spindle rotation. This vertical drilling machine can use manual feed, telescopic rod feed (including electric, pneumatic, and hydraulic) to drive the spindle movement.
[0068] Optionally, depending on the actual processing requirements, the vertical drilling machine may also include more spindles and motor units, especially more paired spindles and motor units, so that the drilling machine can simultaneously perform drilling operations on multiple parts of the workpiece, thereby improving drilling efficiency.
[0069] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the positioning mechanism can (in) Figure 3 The positioning mechanism (located between the first spindle 11 and the second spindle 12 in the left-right direction) is used to clamp and fix workpieces such as the guide rail 100. The positioning mechanism may include a first positioning mechanism 40, a second positioning mechanism 50, and a lateral positioning mechanism 60. When drilling a workpiece, the workpiece can pass through the first positioning mechanism 40, the lateral positioning mechanism 60, and the second positioning mechanism 50 in sequence; that is, the channels for the workpiece to pass through the first positioning mechanism 40, the second positioning mechanism 50, and the lateral positioning mechanism 60 can be aligned. The first positioning mechanism 40 can (in the left-right direction) be positioned between the first spindle 11 and the second spindle 12 to clamp and fix workpieces such as the guide rail 100. Figure 3 The second positioning mechanism 50 is positioned above the spindle (vertically) to clamp at least part of the un-drilled portion of the workpiece, such as a guide rail. Figure 3 The upper and lower parts of the workpiece (located below the spindle) are used to clamp at least part of the drilled portion of the workpiece, such as the guide rail. The lateral positioning mechanism can be located on the side of the workpiece, such as the guide rail, to clamp the workpiece from the side.
[0070] Preferably, the horizontal height of the lateral positioning mechanism 60 can be approximately the same as or consistent with the horizontal height of the first spindle 11 and / or the second spindle 12. In particular, the lateral positioning mechanism 60 can be disposed on the side of the drilling area of the drilling machine to improve the positioning accuracy of the vertical drilling machine at the drilling area.
[0071] like Figure 5 As shown, the first positioning mechanism 40 may include a plurality of first positioning members 41, a plurality of first positioning plates 42, and a plurality of first guide wheels 43. The first positioning member 41 may be a transmission structure (e.g., a hydraulic cylinder, a pneumatic cylinder, etc.), which may have a clamping portion 411 capable of extending and abutting against the workpiece. Preferably, the outer end face of the clamping portion 411 (i.e., the end face used to abut against the workpiece) can conform to the workpiece; for example, such as... Figure 5 As shown, the part of the guide rail 100 that contacts the clamping part 411 is a plane, and the outer end face of the clamping part 411 can also be a plane.
[0072] The first positioning mechanism 40 may include at least two opposing and spaced-apart first positioning plates 42. A workpiece such as a guide rail 100 may be positioned between the opposing two first positioning plates 42. The distance between the two first positioning plates 42 may be slightly greater than the thickness of the workpiece such as the guide rail, to facilitate the passage of the workpiece through the first positioning mechanism 40. A plurality of first positioning members 41 may be disposed on at least one (e.g., one of the two first positioning plates 42) of the first positioning plate 42, with one end of the first positioning member 41 having a pressing portion 411 facing the opposite (e.g., the other of the two first positioning plates 42) first positioning plate 42. The first positioning member 41 may extend the pressing portion 411 to press and abut the workpiece against the opposite first positioning plate 42.
[0073] like Figure 4 and Figure 5 As shown, multiple first guide wheels 43 can be provided on both sides of the gap between the two first positioning plates 42, and a channel for the workpiece to pass through can be formed between the first guide wheels 43 on both sides. Preferably, the circumferential surface of the first guide wheel 43 can fit against the side of the workpiece. Alternatively, multiple overlapping first guide wheels 43 can be provided to increase the degree of contact between the first guide wheel 43 and the workpiece. For example, as shown... Figure 5 As shown, because the guide rail has two protruding structures on its side, the first guide wheel 43 can be arranged in a form where two guide wheels overlap (i.e., the two guide wheels are arranged coaxially). The first guide wheel 43 can improve the stability of the guide rail during movement and the positioning accuracy during drilling.
[0074] like Figure 3 , Figure 4 and Figure 5 As shown, for example, the first positioning plates 42 on both the left and right sides can be fixedly connected to the base 30. The inactive parts of the plurality of first positioning members 41 can be fixedly connected to the first positioning plate 42 on the right side, and the pressing parts of the plurality of first positioning members 41 can extend toward the first positioning plate 42 on the left side. The two ends of the axles of the plurality of first guide wheels 43 can be fixedly connected to the two sides of the first positioning members 42 respectively, and the wheel bodies of the plurality of first guide wheels 43 can roll with the movement of the guide rail 100.
[0075] The vertical drilling machine may also include a traction lifting device, which can be positioned above the first positioning mechanism 40 for traction and movement of the workpiece. Understandably, in actual production, the workpiece can be lifted and allowed to enter the positioning mechanism through the opening at the top of the first positioning mechanism 40 (the gap between the two first positioning elements 41 and the multiple first guide wheels 43). Various traction lifting devices, such as overhead rails or hammocks, can be used to lift and lower the workpiece. For example, a servo traction mechanism can be used to place the workpiece inside the drilling machine, and the servo motor can calculate the vertical movement distance of the workpiece, such as the guide rail.
[0076] Preferably, an auxiliary positioning mechanism, such as a funnel-shaped auxiliary positioning mechanism, can be provided at the upper opening of the first positioning mechanism 40 so that workpieces such as guide rails can smoothly enter the positioning mechanism.
[0077] like Figure 6 As shown, the second positioning mechanism 50 may include a plurality of second positioning elements 51, a plurality of second positioning plates 52, and a plurality of second guide wheels 53. The second positioning element 51 may be a transmission structure (e.g., a hydraulic cylinder, a pneumatic cylinder, etc.), which may have a positioning pin 511 that can extend out and partially extend into the workpiece hole (especially the hole formed on the workpiece by this drilling machine).
[0078] Preferred, such as Figure 6 As shown, the end of the locating pin 511 may have a tapered portion that can at least partially extend into a hole in the workpiece. The diameter of the locating pin 511 (e.g., the major diameter of the tapered portion, or the diameter of the portion of the locating pin that does not form a tapered portion) may be slightly larger than the diameter of the hole in the workpiece (if the hole is a special hole such as a stepped hole, the diameter of the locating pin 511 may be larger than the diameter of the opening on the side of the workpiece facing the locating pin), so that after the tapered portion of the locating pin 511 at least partially enters the hole, it can press the workpiece against the second locating plate 52 on the opposite side to form a limit on the workpiece (in particular, after the locating pin 511 partially extends into the hole, it can also form a limit on the workpiece along its length direction). It is understandable that even when the locating pin 511 is extended, its axial direction is not perfectly aligned with the center of the hole on the workpiece. During the extension of the locating pin 511, its tapered portion can slide at least partially into the hole along the wall, thereby achieving accurate positioning and error calibration of the workpiece. Existing drilling machines generate symmetry and spacing errors during continuous drilling operations on guideways. Multiple movements of the drill bit or workpiece accumulate errors, leading to a gradual decrease in drilling position accuracy. The vertical drilling machine provided in this application, however, can effectively correct various errors caused by workpiece movement by using the locating pin 511 to position and calibrate the already machined holes, thereby significantly improving drilling accuracy.
[0079] The second positioning mechanism 50 may include at least two opposing and spaced-apart second positioning plates 52. A workpiece such as a guide rail may be positioned between the opposing two second positioning plates 52. The distance between the two second positioning plates 52 may be slightly greater than the thickness of the workpiece such as the guide rail, to facilitate the passage of the workpiece through the second positioning mechanism 50. Multiple second positioning elements 51 may be disposed on at least one (e.g., one of the two second positioning plates 52) of the second positioning plate 52, with one end of the second positioning element 51 having a positioning pin 511 facing the opposite (e.g., the other of the two second positioning plates 52) second positioning plate 52. The second positioning element 51 may extend the positioning pin 511 to press and abut against the opposite second positioning plate 52.
[0080] like Figure 6 As shown, multiple second guide wheels 53 can be provided on both sides of the gap between the two second positioning plates 52, and a channel for the workpiece to pass through can be formed between the second guide wheels 53 on both sides. Preferably, the circumferential shape of the second guide wheel 53 can fit against the side of the workpiece. Alternatively, multiple overlapping (i.e., coaxially arranged) second guide wheels 53 can be provided to increase the degree of contact between the second guide wheel 53 and the workpiece. For example, as shown... Figure 5 As shown, since the guide rail 100 has two protruding structures on its side, the second guide wheel 53 can be arranged in an overlapping manner. The second guide wheel 53 can improve the stability of the guide rail during movement and the positioning accuracy during drilling.
[0081] like Figure 3 , Figure 4 and Figure 6 As shown, for example, the second positioning plates 52 on both the left and right sides can be fixedly connected to the base 30. The inactive parts of the plurality of second positioning members 51 can be fixedly connected to the second positioning plate 52 on the right side, and the positioning pins of the plurality of second positioning members 51 can extend toward the second positioning plate 52 on the left side. The two ends of the axles of the plurality of second guide wheels 53 can be fixedly connected to the two sides of the second positioning members 52 respectively, and the wheel bodies of the plurality of second guide wheels 53 can roll with the movement of the guide rail 100.
[0082] like Figure 4 and Figure 7 As shown, the lateral positioning mechanism 60 may include a lateral positioning member 61, a lateral clamping block 62, and a lateral positioning part 63. The lateral clamping block 62 and the lateral positioning part 63 may be respectively disposed on two sides of the workpiece. The lateral positioning member 61 may be a transmission structure (e.g., a hydraulic cylinder, a pneumatic cylinder, etc.), and the lateral positioning member 61 may be connected to the lateral clamping block 62, and may push the lateral clamping block 62 toward the lateral positioning part 63, so that the two sides of the workpiece (the two sides in the width direction of the workpiece) are respectively pressed against the lateral clamping block 62 and the lateral positioning part 63 to achieve positioning and limiting of the workpiece. The transmission extension direction of the first positioning member 41 and the second positioning member 51 may be perpendicular to the transmission extension direction of the lateral positioning member 61.
[0083] Preferably, the lateral clamping block 62 and the lateral positioning part 63 can be contour blocks formed according to the shape of the workpiece (especially the shape of the two sides). For example, Figure 7As shown, the side of the guide rail 100 can have two protruding structures. The portions of the lateral clamping block 62 and the lateral positioning part 63 that are in contact with the guide rail can form protrusions, which can fit into the groove between the two protruding structures of the guide rail 100. It can be understood that the lateral clamping block 62 and the lateral positioning part 63 forming a contour block can increase their fit with the workpiece and improve the clamping and positioning effect (for example, the contour block can form a limit on the thickness direction of the workpiece).
[0084] It is understood that, based on the aforementioned description of the positioning mechanism, the first positioning mechanism 40, the second positioning mechanism 50, and the lateral positioning mechanism 60 can work together to effectively position and limit the workpiece such as the guide rail, thus ensuring the drilling accuracy of the vertical drilling machine.
[0085] The first motor assembly 21, the second motor assembly 22, the first positioning mechanism 40, the second positioning mechanism 50, and the lateral positioning mechanism 60 can all be connected to the base 30 to provide support for the aforementioned components. It is understood that the specific shape and structure of the base 30 can be changed according to actual usage scenarios and requirements; for example, the base can be a floor-mounted pedestal or a bracket connected to a wall.
[0086] During drilling operations, after setting the guide rail or other workpiece in the initial drilling position, the first positioning element 41, the second positioning element 51, and the lateral positioning element 61 can be activated simultaneously or sequentially (extending their telescopic structures) to fully position the guide rail. Then, the first motor group 21 and / or the second motor group 22 can be activated to begin drilling. After completing one drilling operation, the first positioning element 41, the second positioning element 51, and the lateral positioning element 61 can be deactivated (retracting their telescopic structures), and the workpiece can be moved to the next drilling position. This process can be repeated until the workpiece is drilled.
[0087] Preferably, the vertical drilling machine can be a CNC drilling machine, that is, the drilling machine can include a CNC system.
[0088] Preferably, the vertical drilling machine may further include a cooling water circulation system, which may include coolant nozzles and a coolant circulation tank. The coolant nozzles spray coolant onto the spindle, drill bit, and workpiece at the drilling location during spindle and drill bit operation, thereby cooling these components. The coolant circulation tank is connected to the coolant nozzles and positioned below the drilling location; it stores circulating coolant and draws coolant from the nozzles during operation.
[0089] It is understandable that the first motor group 21, the second motor group 22, the first positioning mechanism 40, the second positioning mechanism 50, and the lateral positioning mechanism 60 of this vertical drilling machine can all be automatically controlled to improve the automation level of the drilling machine. In particular, multiple vertical drilling machines can also be combined to form an automated production line, thereby improving the automation level of guide rail drilling operations.
[0090] It is understandable that this vertical drilling machine is suitable for drilling workpieces that are vertically suspended. This drilling machine has lower requirements for the installation environment, such as the flatness of the ground (unlike traditional horizontal and bench drilling machines), and can be used in a wide range of production environments. It can also avoid the impact of environmental factors such as the levelness of the ground on the drilling quality.
[0091] It is understandable that the vertical drilling machine can be appropriately adjusted and modified according to the specifications of the actual workpiece being processed. For example, when the workpiece is long, multiple first positioning mechanisms 40, multiple second positioning mechanisms 50, and multiple lateral positioning mechanisms 60 can be set at intervals.
[0092] The following is a brief description of some of the beneficial effects of the above-described embodiments of this application.
[0093] The vertical drilling machine provided in this application is suitable for drilling slender workpieces such as guide rails. During drilling operations, this vertical drilling machine can vertically position the guide rails. Compared to existing drilling machines that require horizontally positioned guide rails, the technical solution of this application effectively reduces the floor space required, improves site utilization, and reduces the impact of environmental factors such as ground flatness on drilling quality. By using a first positioning mechanism, a second positioning mechanism, and a lateral positioning mechanism to limit and position the workpiece, the cumulative error, symmetry error, and spacing error generated during drilling can be effectively reduced, thus improving drilling accuracy.
[0094] It is understood that, in this application, when the number of parts or components is not specifically limited, the number can be one or more, where multiple refers to two or more. For cases where the number of parts or components shown in the drawings and / or described in the specification is, for example, two, three, four, etc., this specific number is generally exemplary and not restrictive, and can be understood as multiple, i.e., two or more; however, this does not mean that this application excludes the case of one.
[0095] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.
