Description

Technical Field

[0001] This application relates to the technical field of drilling machines, and particularly to a vertical drilling machine. Background Art

[0002] Some guide rails need to be drilled along their length direction (the extending direction of the track) due to the requirements of installation, positioning, etc., especially drilling holes at uniform intervals. The existing drilling machines for drilling guide rails generally consist of structures such as a bed, a main shaft, a workbench, and a fixture. Among them, the beds and workbenches of the existing technology machines are usually placed horizontally, and the guide rail to be drilled is horizontally installed on the workbench through the fixture. After the guide rail is installed on the workbench, the drilling operation of the guide rail can be realized by horizontally moving the main shaft or horizontally moving the workbench.

[0003] The above-mentioned existing drilling machines for drilling guide rails have the following disadvantages: 1. Since the guide rail needs to be placed horizontally for drilling operations, the floor area occupied by the guide rail and the machine is large and the site utilization rate is low. 2. When the guide rail is drilled, it needs to move along its extending direction. High drilling accuracy depends on the high moving accuracy of the main shaft or the workbench. And cumulative errors will be formed during the movement of the main shaft or the workbench, further affecting the drilling accuracy. At the same time, the large floor area and the high processing accuracy requirements will also increase the manufacturing difficulty and production cost of the equipment. Based on the state of the above-mentioned existing technology, there is an urgent need to provide a new type of drilling machine suitable for the drilling operation of guide rail processing to improve at least one of the aforementioned problems of the existing technology.

[0059] The exemplary implementation manners of the present application will be described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, rather than to exhaust all feasible manners of the present application, nor to limit the scope of the present application.

[0060] In the present application, "transmission connection" means a connection that can transmit torque between two components, including direct connection or indirect connection between the two components.

[0061] The implementation manner of the present application provides a vertical drilling machine (hereinafter, sometimes simply referred to as "drilling machine"), which is applicable to the processing and manufacturing of slender structural parts such as the guide rail 100. As Figure 1 shown, the vertical drilling machine may include a first main shaft 11, a second main shaft 12, a first motor group 21, a second motor group 22, a base 30, and a positioning mechanism.

[0062] This vertical drilling machine is preferably a vertical two-way drilling machine, that is, it can perform drilling on the workpiece to be processed from two opposite directions.

[0063] Specifically, the first main shaft 11 and the second main shaft 12 can be arranged oppositely, and the axial directions of the first main shaft 11 and the second main shaft 12 can be parallel. Preferably, the axial directions of the first main shaft 11 and the second main shaft 12 can coincide, and the outer ends thereof connected to the drill bits can be opposite. In other possible embodiments, the first main shaft 11 and the second main shaft 12 can also be offset in the height direction (especially offset by the hole positions of one or more of the positioning mechanisms described later). Workpieces such as the guide rail 100 to be drilled can be vertically arranged (the length extension direction of slender workpieces such as the guide rail is arranged in the vertical direction) between the first main shaft 11 and the second main shaft 12, that is, the first main shaft 11 and the second main shaft 12 can extend in the horizontal direction. The outer ends (the ends facing the workpieces such as the guide rail) of the first main shaft 11 and the second main shaft 12 can be installed with drill bits of the same diameter or different diameters according to actual processing needs. When performing drilling processing, the first main shaft 11 and / or the second main shaft 12 can move towards the workpiece to drill the workpiece simultaneously or successively. It can be understood that the vertical drilling machine of the present application can also perform a processing operation of drilling only one side of the workpiece according to actual processing needs.

[0064] Exemplarily, as Figure 3 shown, when the drilled hole pattern of the guide rail 100 is a stepped hole, the first main shaft 11 and the second main shaft 12 can be respectively connected to drill bits of different diameters, and drilling operations can be successively performed on both sides of the guide rail 100.

[0065] As Figure 1 and Figure 2 shown, the first motor group 21 can be connected to the first main shaft 11, and the second motor group 22 can be connected to the second main shaft 12. Drilling processing operations can be performed by driving the main shaft and the connected drill bit to rotate and move through the motors. Specifically, both the first motor group 21 and the second motor group 22 can include a rotating motor and a feeding motor (that is, the first motor group 21 can include a first rotating motor 211 and a first feeding motor 212, and the second motor group 22 can include a second rotating motor 221 and a second feeding motor 222). Both the rotating motor and the feeding motor can be in transmission connection with the corresponding main shaft. The rotating motor in transmission connection with the main shaft can drive the main shaft to rotate, and the transmission form between the rotating motor and the main shaft can be gear transmission, belt transmission, etc. The feeding motor in transmission connection with the main shaft can drive the main shaft to move horizontally, and the transmission form between the feeding motor and the main shaft can be lead screw transmission, etc. Preferably, the feeding motor can be a servo motor to improve the accuracy of feeding control.

[0066] It can be understood that the first motor group 21 and the second motor group 22 can also only respectively include a motor for driving the main shaft to rotate. The vertical drilling machine can drive the main shaft to move by means of manual feeding, telescopic rod feeding (including electric, pneumatic, hydraulic), etc.

[0067] Optionally, according to the actual processing technology requirements, the vertical drilling machine may further include more spindles and motor sets, especially more pairs of spindles and motor sets, so that the drilling machine can perform drilling operations on multiple parts of the workpiece simultaneously to improve the efficiency of the drilling operation.

[0068] Furthermore, as Figure 1 , Figure 3 and Figure 4 shown, the positioning mechanism can be (in the left - right direction in Figure 3 ) arranged between the first spindle 11 and the second spindle 12 for clamping and fixing workpieces such as the guide rail 100. The positioning mechanism can include a first positioning mechanism 40, a second positioning mechanism 50, and a lateral positioning mechanism 60. When drilling the 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 passing the workpiece of 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 be (in the up - down direction in Figure 3 ) relatively arranged above the spindle for clamping at least part of the un - drilled part of workpieces such as the guide rail. The second positioning mechanism 50 can be (in the up - down direction in Figure 3 ) relatively arranged below the spindle for clamping at least part of the drilled part of workpieces such as the guide rail. The lateral positioning mechanism can be arranged on the side of workpieces such as the guide rail for clamping the workpiece on the side of the workpiece.

[0069] 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 arranged on the side of the drilling processing area of the drilling machine to improve the positioning accuracy at the drilling area of the vertical drilling machine.

[0070] As Figure 5 shown, the first positioning mechanism 40 can 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 can be a transmission structure (such as a hydraulic cylinder, a pneumatic cylinder, etc.), which can have a pressing part 411 that can extend and abut against the workpiece. Preferably, the outer end face of the pressing part 411 (i.e., the end face for abutting against the workpiece) can fit the workpiece. Exemplarily, as Figure 5 shown, the part of the guide rail 100 in contact with the pressing part 411 is a plane, and the outer end face of the pressing part 411 can also be a plane.

[0071] The first positioning mechanism 40 may include at least two relatively arranged and spaced-apart first positioning plates 42, and workpieces such as the guide rail 100 may be arranged in the middle of two opposite 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, so as to facilitate the workpiece to pass through the first positioning mechanism 40. A plurality of first positioning members 41 may be arranged on at least one (for example, one of the two first positioning plates 42), and the end of the first positioning member 41 provided with the pressing portion 411 may face the opposite (for example, the other of the two first positioning plates 42) first positioning plate 42, and the first positioning member 41 may extend the pressing portion 411 to press and adhere the workpiece against the opposite first positioning plate 42.

[0072] As Figure 4 and Figure 5 shown, a plurality of first guide wheels 43 may be arranged on both sides of the interval between the two first positioning plates 42, and a passage for the workpiece to pass through may be formed between the first guide wheels 43 on both sides. Preferably, the peripheral surface of the first guide wheel 43 may be attached to the side surface of the workpiece. Alternatively, a plurality of overlapping first guide wheels 43 may be provided to increase the degree of attachment between the first guide wheels 43 and the workpiece. Exemplarily, as Figure 5 shown, since the side surface of the guide rail has two protruding structures, the first guide wheel 43 may be arranged in the form of two overlapping guide wheels (that is, two guide wheels are coaxially arranged). The first guide wheel 43 can improve the stability during the movement of the guide rail and the positioning accuracy during drilling.

[0073] As Figure 3 、 Figure 4 and Figure 5 shown, exemplarily, the first positioning plates 42 on the left and right sides may be fixedly connected to the base 30, the inactive parts of the plurality of first positioning members 41 may be fixedly connected to the right first positioning plate 42, and the pressing portions of the plurality of first positioning members 41 may extend toward the left first positioning plate 42. Both ends of the wheel axles of the plurality of first guide wheels 43 may be respectively fixedly connected to both sides of the first positioning member 42, and the wheel bodies of the plurality of first guide wheels 43 may roll along with the movement of the guide rail 100.

[0074] The vertical drilling machine may further include a traction lifting device, and the traction lifting device may be arranged above the first positioning mechanism 40 for traction and movement of the workpiece. It can be understood that during actual production, the workpiece can be lifted and enter the positioning mechanism through the opening (the gap between the two first positioning members 41 and the plurality of first guide wheels 43) at the upper part of the first positioning mechanism 40. Various traction lifting devices such as suspension rails and hammocks can be used to lift and lower the workpiece. For example, a servo traction mechanism can be used to place the workpiece in the drilling machine, and the servo motor can calculate the vertical movement distance of the workpiece such as the guide rail.

[0075] Preferably, an auxiliary positioning mechanism, such as a funnel-shaped auxiliary positioning mechanism, can also be provided at the upper opening of the first positioning mechanism 40 to facilitate the smooth entry of workpieces such as guide rails into the positioning mechanism.

[0076] As Figure 6 shown, the second positioning mechanism 50 can include a plurality of second positioning members 51, a plurality of second positioning plates 52, and a plurality of second guide wheels 53. The second positioning member 51 can be a transmission structure (such as a hydraulic cylinder, a pneumatic cylinder, etc.), which can have a positioning pin 511 that can extend and partially penetrate into the hole of the workpiece (especially the hole formed by the present drilling machine on the workpiece).

[0077] Preferably, as Figure 6 shown, a tapered portion can be formed at the end of the positioning pin 511, and the tapered portion can at least partially penetrate into the hole on the workpiece. The diameter of the positioning pin 511 (for example, the major diameter of the tapered portion, or the diameter of the portion of the positioning pin that does not form the tapered portion) can be slightly larger than the diameter of the hole on the workpiece (if the hole is a special hole such as a stepped hole, the diameter of the positioning pin 511 can be larger than the diameter of the opening of the workpiece facing the positioning pin side), so that after at least part of the tapered portion of the positioning pin 511 enters the hole, the workpiece can be pressed against the second positioning plate 52 on the opposite side to form a limit for the workpiece (in particular, after the positioning pin 511 partially penetrates into the hole, it can also form a limit for the workpiece along its length direction). It can be understood that even when the positioning pin 511 is extended, if the axis of the positioning pin 511 is not completely aligned with the center of the hole on the workpiece, during the extension of the positioning pin 511, at least part of the tapered portion of the positioning pin 511 can slide into the hole along the wall of the hole, thereby realizing the accurate positioning and error calibration of the positioning pin 511 for the workpiece. In the prior art, when a drilling machine performs continuous drilling operations on a guide rail, symmetry errors and spacing errors will be formed, and cumulative errors will be formed by moving the drill bit or the workpiece multiple times, resulting in a gradual decrease in the position accuracy of the drilling. However, the vertical drilling machine provided in the present application can effectively correct various errors formed by moving the workpiece through the positioning and error calibration of the positioning pin 511 for the processed hole, thereby effectively improving the drilling processing accuracy.

[0078] The second positioning mechanism 50 can include at least two relatively and spaced second positioning plates 52, and workpieces such as guide rails can be arranged between the two opposite second positioning plates 52. The distance between the two second positioning plates 52 can be slightly larger than the thickness of the workpiece such as the guide rail to facilitate the passage of the workpiece through the second positioning mechanism 50. A plurality of second positioning members 51 can be arranged on at least one (for example, one of the two second positioning plates 52), and the end of the second positioning member 51 provided with the positioning pin 511 can face the second positioning plate 52 on the opposite side (for example, the other of the two second positioning plates 52), and the second positioning member 51 can extend the positioning pin 511 to press and stick the workpiece against the second positioning plate 52 on the opposite side.

[0079] As shown Figure 6 in the figure, a plurality of second guide wheels 53 can be provided on both sides of the interval between the two second positioning plates 52, and a passage for the workpiece to pass through can be formed between the second guide wheels 53 on both sides. Preferably, the peripheral surface shape of the second guide wheel 53 can conform to the side surface of the workpiece. Alternatively, a plurality of overlapping (i.e., coaxially arranged) second guide wheels 53 can be provided to increase the degree of conformity between the second guide wheel 53 and the workpiece. Exemplarily, as shown Figure 5 in the figure, since the side surface of the guide rail 100 has two convex structures, the second guide wheel 53 can be arranged in the form of two overlapping guide wheels. The second guide wheel 53 can improve the stability during the movement of the guide rail and the positioning accuracy during drilling.

[0080] As shown Figure 3 , Figure 4 and Figure 6 in the figure, exemplarily, the second positioning plates 52 on the left and right sides can be fixedly connected to the base 30, and 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. Both ends of the wheel axles of the plurality of second guide wheels 53 can be respectively fixedly connected to both sides of the second positioning member 52, and the wheel bodies of the plurality of second guide wheels 53 can roll along with the movement of the guide rail 100.

[0081] As shown Figure 4 and Figure 7 in the figure, the lateral positioning mechanism 60 can include a lateral positioning member 61, a lateral pressing block 62 and a lateral positioning portion 63. The lateral pressing block 62 and the lateral positioning portion 63 can be respectively arranged on two side surfaces of the workpiece. The lateral positioning member 61 can be a transmission structure (such as a hydraulic cylinder, a pneumatic cylinder, etc.), and the lateral positioning member 61 can be connected to the lateral pressing block 62 and can push the lateral pressing block 62 toward the lateral positioning portion 63, so that the two side surfaces of the workpiece (the two side surfaces in the width direction of the workpiece) are respectively pressed against the lateral pressing block 62 and the lateral positioning portion 63 to achieve the positioning and limiting of the workpiece. The transmission telescopic directions of the first positioning member 41 and the second positioning member 51 can be perpendicular to the transmission telescopic direction of the lateral positioning member 61.

[0082] Preferably, the lateral pressing block 62 and the lateral positioning portion 63 can be profiling blocks formed according to the shape of the workpiece (especially the shapes of the two side surfaces). Exemplarily, as shown Figure 7As shown, two convex structures may be formed on the side surface of the guide rail 100. The portions of the lateral pressing block 62 and the lateral positioning portion 63 for contacting the guide rail may form protruding portions, and the protruding portions may fit into the grooves between the two convex structures of the guide rail 100. It can be understood that forming a profiling block with the lateral pressing block 62 and the lateral positioning portion 63 can increase the degree of fit with the workpiece and improve the pressing and positioning effects (for example, the profiling block can form a limit in the thickness direction of the workpiece).

[0083] It can be understood that based on the description of the foregoing positioning mechanism, the first positioning mechanism 40, the second positioning mechanism 50, and the lateral positioning mechanism 60 can jointly form effective positioning and limiting for workpieces such as guide rails, and can ensure the drilling accuracy of the vertical drilling machine.

[0084] 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 can all be connected to the base 30 to form support for the above-mentioned components. It can be understood that the specific shape and structure of the base 30 can be changed according to the actual use scenario and requirements. For example, the base can be a base placed on the ground or a bracket connected to the wall.

[0085] When performing drilling operations, after setting workpieces such as guide rails at the initial drilling position, each of the first positioning members 41, the second positioning members 51, and the lateral positioning members 61 can be turned on (extend their telescopic structures) simultaneously or successively to fully position the guide rail. Then, the first motor group 21 and / or the second motor group 22 can be turned on to start the drilling operation. After completing one drilling operation, each of the first positioning members 41, the second positioning members 51, and the lateral positioning members 61 can be turned off (retract their telescopic structures), and the workpiece can be moved to the next drilling position. After moving to the next drilling position, the above process can be repeated until the workpiece drilling is completed.

[0086] Preferably, the vertical drilling machine can be a numerically controlled drilling machine, that is, the drilling machine can include a numerical control system.

[0087] Preferably, the vertical drilling machine can further include a cooling water circulation system. The cooling water circulation system can include a coolant spray pipe and a coolant circulation tank. The coolant spray pipe can spray coolant onto the spindle, the drill bit, and the drilling area of the workpiece when the spindle and the drill bit are working to cool the spindle, the drill bit, and the workpiece. The coolant circulation tank can be connected to the coolant spray pipe and is arranged below the drilling processing position. It can be used to store the circulating liquid and pick up the coolant when the coolant spray pipe is working.

[0088] It can be understood 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 the vertical drilling machine can all adopt automatic control to improve the automatic control level of the drilling machine. In particular, multiple vertical drilling machines can also form an automatic production line to improve the automation level of the guide rail drilling operation.

[0089] It can be understood that the vertical drilling machine is suitable for vertically hoisting workpieces for drilling operations. This drilling machine has relatively low requirements for the installation environment such as the ground flatness (different from traditional horizontal and bench drilling machines), can be applied to a wide range of production environments, and can also avoid the influence of environmental factors such as ground levelness on the drilling quality.

[0090] It can be understood that the vertical drilling machine can be appropriately adjusted and deformed according to the specifications of the actual processed workpiece. For example, when the workpiece is relatively long, multiple first positioning mechanisms 40, multiple second positioning mechanisms 50, and multiple lateral positioning mechanisms 60 can be arranged at intervals.

[0091] The following briefly describes some beneficial effects of the above embodiments of the present application.

[0092] The vertical drilling machine provided by the embodiment of the present application is suitable for drilling operations on slender workpieces such as guide rails. When performing drilling operations, the vertical drilling machine can set the guide rail vertically. Compared with the existing drilling machines that require the guide rail to be set horizontally, the technical solution of the present application can effectively reduce the floor area, improve the site utilization rate, and reduce the influence of environmental factors such as ground flatness on the drilling quality. By jointly limiting and positioning the workpiece through the first positioning mechanism, the second positioning mechanism, and the lateral positioning mechanism, the cumulative error, symmetry error, and spacing error generated during the drilling process can be effectively reduced, and the drilling accuracy can be improved.

[0093] It can be understood that in the present application, when the number of components or members is not specifically limited, the number can be one or more, and here the multiple means two or more. For the specific number of components or members shown in the drawings and / or described in the specification, such as two, three, four, etc., this specific number is usually exemplary rather than restrictive, and can be understood as multiple, that is, two or more. However, this does not mean that the present application excludes the case of one.

[0094] It should be understood that the above embodiments are merely exemplary and do not limit the present application. Those skilled in the art can make various modifications and changes to the above embodiments under the teaching of the present application without departing from the scope of the present application.
