Description

Technical Field

[0001] The invention relates to the technical field of inclined hole positioning processing, and more specifically, to a metal base inclined hole positioning processing device and a processing method thereof. Background Art

[0002] Bevel hole machining is a machining technique used to drill holes in a workpiece at a certain angle to the workpiece surface. This machining method is often used in situations where parts need to be installed or fixed at a specific angle, such as in mold manufacturing, automotive parts, aerospace, etc. Metal bases usually refer to metal structural parts used to support, fix or install other components. They are widely used in various industrial and manufacturing fields, including machinery, electronics, automobiles, aerospace, etc.

[0003] Most existing inclined hole processing devices use a three-jaw chuck to clamp the metal base, and then use a rotating base to adjust the angle of the metal base, and then the drill bit completes the final inclined hole processing. The three-jaw chuck can fit the side wall of the circular workpiece, which is convenient for the inclined hole processing of the circular workpiece. However, the metal bases in actual production include not only circular workpieces, but also square workpieces. The three-jaw chuck cannot effectively clamp the square workpiece, so it is not suitable for the processing of square metal bases.

[0004] Different from ordinary drilling processing methods, during the inclined hole processing, there is a certain angle between the processing direction of the drill bit and the axial direction of the metal base to ensure the accuracy of the inclined hole positioning. The end of the drill bit needs to be thinner to avoid displacement when the drill bit contacts the surface of the metal base, but if the end of the drill bit is too thin, the probability of the drill bit breaking during the subsequent drilling process will increase. During the continuous drilling process, the drill bit is also prone to jitter due to insufficient lubrication, and in severe cases, it may even cause the drill bit to break. Whether the drill bit end is too thin or the drill bit breaks due to insufficient lubrication, it will affect the service life of the drill bit.

[0005] At the same time, although the rotating base can adjust the drilling angle, it will also rotate due to the pressure of the drill bit during the drilling process, causing the metal base to rotate during the drilling process. This further causes the angle of the inclined hole to deviate, making the finished product fail to meet production requirements. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a metal base oblique hole positioning processing device and a processing method for metal bases that can perform oblique hole processing on both square and round metal bases, adopt a pre-positioning processing method to ensure accurate positioning of the oblique hole while avoiding drill breakage that affects the service life, and provide auxiliary support to the metal base during the oblique hole processing to avoid the metal base rotating and causing the processing angle to shift.

[0010] By adopting the above technical solution, the rotation of the drilling disk can realize the switching between the pre-drilling drill bit and the secondary drilling drill bit. When performing inclined hole processing, the pre-drilling drill bit is first used to pre-position the metal base, and then the secondary drilling drill bit is used to perform secondary drilling processing.

[0015] By adopting the above technical solution, when the oblique hole is processed on the circular metal base, the four sets of sliding seats slide along the chuck slide groove respectively, so that the arc-shaped limit part on the clamping piece fits with the side wall of the circular metal base, thereby completing the clamping. When the oblique hole is processed on the square metal base, the four sets of sliding seats slide along the chuck slide groove respectively, so that the rectangular limit part on the clamping piece fits with the side wall of the square metal base, thereby completing the clamping.

[0019] A method for positioning and processing an inclined hole of a metal base, according to the above-mentioned device for positioning and processing an inclined hole of a metal base, comprises the following steps: S1. When processing a circular metal base, the four groups of clamping chuck assemblies slide relative to the chuck slide groove, so that the arc-shaped limiting portion on the clamping member fits with the side wall of the circular metal base to complete the clamping. When processing a square metal base, the four groups of clamping chuck assemblies slide relative to the chuck slide groove, so that the rectangular limiting portion on the clamping member fits with the side wall of the square metal base to complete the clamping; S2. After the circular metal base or the square metal base is clamped, the rotating seat rotates relative to the base according to the angle of the inclined hole, and the clamping limit unit and the circular metal base or the square metal base are simultaneously driven to rotate, so as to complete the adjustment of the processing angle of the circular metal base or the square metal base; S3. According to the angle and position of the circular metal base or the square metal base, the lifting platform assembly is lifted and lowered, and the rotating plate is rotated relative to the mounting frame, so that the rotating plate is fitted with the clamping limit unit and the side wall of the mounting platform, and the auxiliary plate is fitted with the bottom of the rotating seat, so as to perform auxiliary limit on the circular metal base or the square metal base; S4, the drilling disk rotates to make the pre-drilled component contact with the round metal base or the square metal base to complete the pre-positioning drilling process. During the processing, the pre-spray head sprays and lubricates the pre-drilled component; S5. The drilling disk continues to rotate to make the secondary drilling assembly contact with the secondary drilling assembly to complete the secondary drilling process. During the processing, the secondary drilling assembly is first processed to half of the predetermined depth, then withdrawn from the inclined hole to complete the debris cleaning, and then processed again. The pre-spray head sprays and lubricates the pre-drilling assembly. During this process, the secondary spray head sprays and lubricates the secondary drilling assembly.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. Set a pre-drilling drill bit with a smaller diameter than the secondary drilling drill bit, and use the rotation of the drilling disk to switch between the pre-drilling drill bit and the secondary drilling drill bit. First use the pre-drilling drill bit to pre-position the metal base, and then use the secondary drilling drill bit to perform secondary drilling. This can not only ensure the accuracy of the inclined hole positioning, but also effectively avoid the drill bit breaking due to the drill bit end being too thin during the drilling process, which affects the service life.

[0021] 2. By setting arc-shaped limiting parts with circular arc structures at the top and bottom of the clamping part and setting a rectangular limiting part with rectangular structure in the middle, the arc-shaped limiting parts can be used to clamp the circular metal base, and the rectangular limiting parts can be used to clamp the square metal base, thereby achieving the purpose of simultaneously performing oblique hole processing on the circular metal base and the square metal base.

[0022] 3. By rotating the rotating plate and the auxiliary plate, the rotating plate and the auxiliary plate are respectively fitted with the side wall of the chuck seat and the bottom of the rotating seat, thereby providing auxiliary support for the rotating seat and the clamping limit unit, effectively preventing the rotating seat from rotating due to force during the inclined hole processing, which ultimately causes the circular metal base and the square metal base to rotate, resulting in the deviation of the drilling angle and affecting the processing quality of the finished product.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0041] See also Figure 1-15 , the present invention provides the following technical solutions: For example, see Figure 1-5, comprising a workbench 1, the workbench 1 is horizontally arranged, and a drilling unit 2 is installed on the top thereof, and a lubricating spray unit 3 is installed at the bottom of the drilling unit 2. When the drilling unit 2 processes the metal base, the lubricating spray unit 3 can continuously lubricate.

[0042] See also Figure 1-4 The drilling unit 2 includes a drilling seat assembly 21 arranged vertically on the workbench 1, and the drilling seat assembly 21 includes a drilling frame 211 arranged vertically on the workbench 1. The drilling frame 211 is installed on one side of the workbench 1, and a drilling clamp 213 is arranged on the side wall close to the center of the workbench 1. A drilling drive 212 is installed on the top of the drilling clamp 213, and a drilling disk 214 is sleeved inside. The side wall of the drilling drive 212 is connected to the drilling frame 211, and can drive the drilling disk 214 to move in the vertical direction. The drilling disk 214 is set to a disc structure, and a driving member that can drive the drilling disk 214 to rotate is arranged inside. A pre-drilling assembly 22 and a secondary drilling assembly 23 are arranged on the drilling disk 214, and a lubricating spray unit 3 for lubrication is arranged on one side of the pre-drilling assembly 22 and the secondary drilling assembly 23.

[0043] See also Figure 1-4 The pre-drilling assembly 22 includes a pre-drilling base 221 disposed through the drilling disk 214 and a pre-drilling drill bit 222 disposed at the bottom of the pre-drilling base 221. A driving member capable of driving the pre-drilling drill bit 222 to rotate is disposed inside the pre-drilling base 221. The secondary drilling assembly 23 includes a secondary drilling base 231 disposed through the drilling disk 214 and a secondary drilling drill bit 232 disposed at the bottom of the secondary drilling base 231. A driving member capable of driving the secondary drilling drill bit 232 to rotate is disposed inside the secondary drilling base 231.

[0044] See also Figure 1-4 The diameter of the pre-drilling drill bit 222 is smaller than that of the secondary drilling drill bit 232. The rotation of the drilling disk 214 can realize the switching between the pre-drilling drill bit 222 and the secondary drilling drill bit 232. When performing inclined hole processing, the pre-drilling drill bit 222 is first used to pre-position the metal base, and then the secondary drilling drill bit 232 is used to perform secondary drilling processing. Not only can the accuracy of the inclined hole positioning be ensured, but also the situation that the drill bit is broken due to the excessive thinness of the drill bit end during the drilling process can be effectively avoided, which affects the service life.

[0045] See also Figure 2-5The lubricating spray unit 3 includes a spray mounting frame 32 installed inside the drilling disk 214, a spray drive 31 is installed on one side wall of the spray mounting frame 32, and a pre-spray pipe 33 and a secondary spray pipe 35 are installed on the other side wall. The pre-spray pipe 33 is connected to the pre-spray head 34, and the secondary spray pipe 35 is connected to the secondary spray head 36. The pre-spray head 34 is arranged on one side of the pre-drilling assembly 22, and the secondary spray head 36 is arranged on one side of the secondary drilling assembly 23. During the drilling process, the pre-spray head 34 and the secondary spray head 36 can be controlled by the spray drive 31 to spray lubricating oil, respectively, to provide lubrication for the pre-drilling drill bit 222 and the secondary drilling drill bit 232, thereby effectively avoiding the shaking and tool breakage caused by insufficient lubrication during the drilling process of the pre-drilling drill bit 222 and the secondary drilling drill bit 232.

[0046] For example 2, please refer to Figure 1-2 and Figure 6-12 , the second embodiment makes the following improvements on the basis of the first embodiment: although through the cooperation between the drilling disk 214, the pre-drilling drill bit 222 and the secondary drilling drill bit 232, the metal base can be pre-positioned and drilled using the pre-drilling drill bit 222, and then the secondary drilling drill bit 232 can be used for secondary drilling to ensure the accuracy of the inclined hole positioning, and avoid the situation where the drill bit is broken due to the drill bit end being too thin during the drilling process, which affects the service life. However, it is still impossible to process the inclined hole for the square metal base 8, so it is necessary to set a clamping limit unit 5 that can process the circular metal base 7 and the square metal base 8 at the same time to ensure the reliable clamping of the circular metal base 7 and the square metal base 8 during the inclined hole processing.

[0047] See also Figure 1-2 and Figure 6-12 A rotating base unit 4 is installed at the top center of the workbench 1, and a clamping and limiting unit 5 is connected to the top of the rotating base unit 4, which can clamp the circular metal base 7 and the square metal base 8 respectively.

[0048] See also Figure 1-2 and Figure 6 The rotating base unit 4 includes a base 41 mounted on the top of the workbench 1. The base 41 is mounted at the center of the workbench 1 and a rotating seat 42 is rotatably mounted thereon. A mounting platform 43 is mounted on the top of the rotating seat 42, and the rotating seat 42 can rotate relative to the base 41. The mounting platform 43 is set as a rectangular structure, and its top is connected to the clamping and limiting unit 5. The rotating seat 42 rotates relative to the base 41, which can synchronously drive the mounting platform 43 and the clamping and limiting unit 5 on its top to rotate, thereby realizing the adjustment of the processing angles of the circular metal base 7 and the square metal base 8.

[0049] See also Figure 1-2 and Figure 7-12The clamping and limiting unit 5 includes a chuck base assembly 51 mounted on the top of the mounting platform 43, and four groups of chuck slide grooves 515 are symmetrically provided on the chuck base assembly 51. A group of clamping chuck assemblies 52 are arranged inside each group of chuck slide grooves 515, and the clamping chuck assembly 52 slides along the chuck slide grooves 515 to clamp the circular metal base 7 and the square metal base 8.

[0050] See also Figure 7-12 The chuck base assembly 51 includes a chuck seat 511 set as a hollow cylindrical structure, and a group of driving cylinders 512 are respectively arranged at the positions corresponding to the positions of the chuck slide groove 515 in the chuck seat 511. The output end of the driving cylinder 512 is connected to a driving gear 513, and a matching gear 514 is sleeved on the driving gear 513 and meshed with it. The matching gear 514 meshes with the clamping chuck assembly 52 installed in the chuck slide groove 515. The driving cylinder 512 can drive the driving gear 513 to rotate, and then drive the clamping chuck assembly 52 to slide along the chuck slide groove 515 through the meshing of the matching gear 514.

[0051] See also Figure 7-12 Each group of clamping chuck assembly 52 includes a sliding seat 521 inserted into the inside of the chuck slide 515, and each group of sliding seat 521 is provided with meshing racks 522 that are adapted to the shape of the matching gear 514 and meshed with each other on both sides. Through the cooperation of the matching gear 514 and the meshing rack 522, the sliding seat 521 can be driven to slide along the chuck slide 515. A clamping member 523 is installed on the top of the sliding seat 521, and a rectangular limiting portion 5232 is provided in the middle of the clamping member 523, and an arc limiting portion 5231 is provided at the top and bottom. The arc limiting portion 5231 is arranged near the center of the chuck base assembly 51, and the shape is adapted to the side wall of the circular metal base 7. The rectangular limiting portion 5232 is arranged as a rectangular structure whose side wall is parallel to the axis of the chuck base assembly 51, and the rectangular limiting portion 5232 is arranged inside the arc limiting portion 5231.

[0052] Specifically, when the oblique hole is processed on the circular metal base 7, the four sets of sliding seats 521 slide along the chuck slot 515 respectively, so that the arc-shaped limit portion 5231 on the clamping piece 523 fits with the side wall of the circular metal base 7, thereby completing the clamping. When the oblique hole is processed on the square metal base 8, the four sets of sliding seats 521 slide along the chuck slot 515 respectively, so that the rectangular limit portion 5232 on the clamping piece 523 fits with the side wall of the square metal base 8, thereby completing the clamping.

[0053] By providing an arc-shaped limiting portion 5231 with an arc structure at the top and bottom of the clamping member 523 and a rectangular limiting portion 5232 with a rectangular structure in the middle, the arc-shaped limiting portion 5231 can be used to clamp the circular metal base 7, and the rectangular limiting portion 5232 can be used to clamp the square metal base 8, thereby achieving the purpose of simultaneously performing oblique hole processing on the circular metal base 7 and the square metal base 8.

[0054] For example 3, please refer to Figure 1-2 and Figure 13-15 , the third embodiment makes the following improvements on the basis of the second embodiment. Although the arc-shaped limiting portion 5231 and the rectangular limiting portion 5232 on the clamping member 523 can respectively clamp the circular metal base 7 and the square metal base 8 to complete the inclined hole processing. However, when the circular metal base 7 and the square metal base 8 are processing the inclined hole, the rotating seat 42 is still rotated by force, which causes the circular metal base 7 and the square metal base 8 to rotate synchronously, resulting in a change in the drilling angle, affecting the processing quality of the finished product. Therefore, an auxiliary support unit 6 is required. During the inclined hole processing process, auxiliary support is provided from both sides of the rotating base unit 4 and the clamping limiting unit 5 to prevent the rotating seat 42 and the clamping limiting unit 5 from rotating and causing a change in the drilling angle.

[0055] See also Figure 1-2 and Figure 13-15 Two groups of auxiliary support units 6 are symmetrically arranged on both sides of the rotating base unit 4, and each group of auxiliary support units 6 includes a lifting platform assembly 61 installed on the top of the workbench 1 and a rotating support assembly 62 installed on the lifting platform assembly 61. The lifting platform assembly 61 can drive the rotating support assembly 62 to move up and down, and the rotating support assembly 62 can mechanically rotate, so as to fit with the side wall of the clamping and limiting unit 5 to provide auxiliary support thereto.

[0056] See also Figure 13-15 The lifting platform assembly 61 includes a rotating frame 612 arranged on the top of the workbench 1. The rotating frame 612 is arranged in a scissor-fork structure, and a lifting platform 613 is installed on the top thereof. The rotating support assembly 62 is installed on the top of the lifting platform 613. A lifting drive 611 is arranged inside the rotating frame 612, and the lifting drive 611 can drive the rotating frame 612 to rotate, thereby completing the lifting and lowering of the rotating support assembly 62.

[0057] See also Figure 13-15The rotating support assembly 62 includes a horizontally arranged mounting frame 621, which is mounted on the top of the lifting platform 613. A rotating plate 623 is rotatably mounted on the end of the mounting frame 621 close to the clamping and limiting unit 5. An auxiliary plate 624 is arranged on the side of the rotating plate 623 close to the clamping and limiting unit 5, and the auxiliary plate 624 is mounted on the bottom of the rotating plate 623 and is arranged vertically to the rotating plate 623. A rotating drive 622 is connected to the side wall of the rotating plate 623 away from the clamping and limiting unit 5, and the rotating drive 622 can drive the rotating plate 623 to rotate relative to the mounting frame 621.

[0058] Specifically, after the clamping and limiting unit 5 completes the clamping of the circular metal base 7 and the square metal base 8 and adjusts the drilling angle, the lifting platform assembly 61 is lifted and lowered according to the position of the clamping and limiting unit 5, and then the rotating plate 623 is driven by the rotating drive 622 to rotate relative to the mounting frame 621, so that the side wall of the rotating plate 623 is in contact with the side wall of the chuck seat 511, and the side wall of the auxiliary plate 624 is in contact with the bottom of the rotating seat 42, so that the rotating seat 42 and the clamping and limiting unit 5 are auxiliary supported by the rotating plate 623 and the auxiliary plate 624.

[0059] By rotating the rotating plate 623 and the auxiliary plate 624, the rotating plate 623 and the auxiliary plate 624 are respectively fitted with the side wall of the chuck seat 511 and the bottom of the rotating seat 42, thereby providing auxiliary support for the rotating seat 42 and the clamping limit unit 5, effectively preventing the rotating seat 42 from being rotated due to force during the inclined hole processing, and ultimately causing the circular metal base 7 and the square metal base 8 to rotate, resulting in the deviation of the drilling angle, affecting the processing quality of the finished product.

[0060] Embodiment 4, a method for positioning and processing an inclined hole of a metal base, according to the above-mentioned device for positioning and processing an inclined hole of a metal base, comprises the following steps: S1. When processing the circular metal base 7, the four groups of clamping chuck assemblies 52 slide relative to the chuck slide groove 515, so that the arc-shaped limiting portion 5231 on the clamping member 523 fits with the side wall of the circular metal base 7 to complete the clamping. When processing the square metal base 8, the four groups of clamping chuck assemblies 52 slide relative to the chuck slide groove 515, so that the rectangular limiting portion 5232 on the clamping member 523 fits with the side wall of the square metal base 8 to complete the clamping.
