Description

Technical Field

[0001] This invention relates to the field of drilling machine technology, and more particularly to a drilling machine for machining the side of a workpiece. Background Technology

[0002] Drilling machines are a general term for mechanical equipment that uses a tool that is harder and sharper than the workpiece to leave holes or openings in the workpiece through rotary cutting or rotary extrusion; they are widely used in the processing and manufacturing of various products.

[0003] Currently, when drilling workpieces using drilling machines, the workpieces are mostly placed horizontally to ensure secure fixation and high drilling quality. However, this method is only suitable for drilling on the main surface of the workpiece (such as the front and back), and cannot effectively drill holes on the sides. Furthermore, most existing drilling machines use single-head processing, meaning they can only process one workpiece at a time, resulting in low processing efficiency and failing to meet production demands.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] Please see the appendix Figure 1 To be continued Figure 6 As shown, this embodiment 1 provides a drilling machine for machining the side of a workpiece, including a base 1, a clamping mechanism, and a drilling mechanism. The base 1 has a working platform 10 and a crossbeam 11 fixed above the working platform 10 by a column. The area on the working platform 10 and below the crossbeam 11 is defined as the drilling station. The clamping mechanism has multiple clamps 20, which are spaced apart along a first horizontal direction on the working platform 10. The multiple clamps 20 can also be positioned along the first horizontal direction... The workpiece moves synchronously in a second horizontal direction perpendicular to the first horizontal direction to move closer to or further away from the drilling station. In addition, each of the fixtures 20 can fix the workpiece P vertically on it. The drilling mechanism is provided with a hanging plate 30 on the crossbeam 11 and a plurality of drill bit modules 31 spaced apart on the hanging plate 30 along the first horizontal direction. The plurality of drill bit modules 31 can move one by one above the plurality of fixtures 20 to drill the side of the workpiece P vertically arranged on the fixture 20.

[0033] As can be seen from the above, compared with the prior art, the fixture in the drilling machine of this embodiment can securely fix the workpiece vertically, thereby enabling the drill bit module to easily drill holes on the side of the workpiece, resulting in high drilling efficiency and high drilling quality. Moreover, the drilling machine of this embodiment is also equipped with multiple fixtures and multiple drill bit modules, which can realize the drilling of multiple workpieces at one time, greatly improving production efficiency and thus well meeting production needs.

[0034] The following is a detailed description of the specific structure of the drilling machine for machining the side of a workpiece as described in this embodiment.

[0035] First, please continue to refer to the appendix. Figure 1 To be continued Figure 5 As shown, the preferred implementation structure of the fixture 20 in this embodiment is as follows: the fixture 20 is provided with a fixture body 200 placed vertically and a positioning component disposed on the fixture body 200 and capable of fixing the workpiece P vertically on the fixture body 200.

[0036] Furthermore, the fixture body 200 is preferably a plate-shaped structure, as shown in the attached figure. Figure 3The fixture body 200 is a rectangular plate shape; and it has a receiving surface 2000 for the workpiece P to abut against. It is understood that, given that the fixture body 200 is placed vertically, one side of the fixture body 200 is used as the receiving surface 2000 for the workpiece P to abut against. Furthermore, based on the arrangement and movement of the multiple fixtures 20, and the need for convenient assembly when installing the workpiece P, this embodiment uses one side of the fixture body 200 along the first horizontal direction as the receiving surface 2000. Specifically, if the first horizontal direction is defined as the left-right direction and the second horizontal direction as the front-back direction, then the left or right side of the fixture body 200 can be used as the receiving surface 2000.

[0037] Furthermore, the positioning component includes multiple first positioning elements 201, second positioning elements 202, and third positioning elements 203. The multiple first positioning elements 201 are spaced apart on the bottom side of the receiving surface 2000 to support the workpiece; the multiple second positioning elements 202 are symmetrically arranged on opposite sides of the receiving surface 2000 to elastically clamp and position the workpiece; the multiple third positioning elements 203 are spaced apart on the receiving surface 2000 to adsorb and position the workpiece. See the appendix for details. Figure 3 and attached Figure 5 As shown. Understandably, the positioning component can reliably and stably restrict and position the workpiece P on the fixture body 200 by providing an upward supporting force (specifically provided by the first positioning member 201), an elastic clamping force in the front-back direction (specifically provided by the second positioning member 202), and an adsorption force (specifically provided by the third positioning member 203).

[0038] Furthermore, the first positioning element 201 can preferably be a positioning block or a positioning pin; the second positioning element 202 can preferably be an elastic clamping block; and the third positioning element 203 can preferably be a vacuum nozzle. The elastic clamping block can be implemented as follows: (See attached diagram) Figure 4 As shown, the elastic clamping block includes a U-shaped block 2020 and a spring block 2021 connected to the inner surface of the groove bottom of the U-shaped block 2020 via a spring, and one end of the spring block 2021 can extend out of the groove of the U-shaped block 2020. Of course, the attached... Figure 4 The elastic clamping block structure shown is only a preferred embodiment, and this embodiment does not impose any limitations on it.

[0039] Furthermore, to better enhance the positioning function of the positioning component on the workpiece P, thereby improving the drilling quality, in this embodiment, the positioning component further includes at least one pin 204 and multiple limiting pins 205, as detailed in the appendix. Figure 3 and attached Figure 5 As shown, at least one of the pins 204 is disposed on the receiving surface 2000 and can be inserted into the insertion hole on the workpiece P, that is: the pin 204 is used for hanging and positioning the workpiece P; a plurality of limiting pins 205 are spaced apart on the two opposite sides of the receiving surface 2000 to restrict the workpiece P, that is: the limiting pins 205 assist the second positioning member 202 in firmly restricting and positioning the workpiece P in the front-back direction.

[0040] Next, please refer to the appendix. Figure 1 and attached Figure 2 As shown, the implementation structure for enabling multiple clamps 20 to perform synchronous reciprocating motion along the second horizontal direction in this embodiment is as follows: a slide rail 12 extending along the second horizontal direction is fixedly laid on the working platform 10; the clamp mechanism is further provided with a slide block 21 slidably disposed on the slide rail 12 by a slider and a drive mechanism A22 disposed on the working platform 10 and capable of driving the slide block 21 to perform linear motion on the slide rail 12, and multiple clamps 20 are arranged side by side and spaced apart along the first horizontal direction on the slide block 21.

[0041] Furthermore, the drive mechanism A22 can preferably be a linear motor or a linear drive mechanism such as a "motor and lead screw module combination", which are conventional technical means in the field of mechanical automation, so they will not be described in detail here.

[0042] Each of the clamps 20 is fixedly connected to the slide 21 by a bracket 23. At that time, the side of the clamp body 200 of each clamp 20 facing away from the bracket 23 is used as the receiving surface 2000.

[0043] Next, please refer to the appendix. Figure 1 and attached Figure 6As shown, the preferred implementation structure of the drill bit module 31 in this embodiment is as follows: the drill bit module 31 is provided with a mounting base 310 that can slide vertically on the hanging plate 30, a drive mechanism B that is provided on the hanging plate 30 and can drive the mounting base 310 to move up and down, a motor 311 provided on the mounting base 310, a drill bit 312 connected to the power output shaft of the motor 311, and a slag suction pipe 313 provided next to the drill bit 312 and connected to an external negative pressure device. Understandably, in the drill module 31, the drive mechanism B can drive the mounting base 310, the motor 311, the drill bit 312, and the slag suction pipe 313 to move up and down together. The motor 311 can drive the drill bit 312 to rotate. That is, the drive mechanism B can cooperate with the motor 311 to make the drill bit 312 drill a hole in the workpiece P. The slag suction pipe 313 can suck up the waste chips generated during drilling, which not only effectively improves the processing environment, but also saves the cutting fluid conventionally used in the prior art (i.e., saves consumables) and saves manpower for cleaning the cutting fluid.

[0044] Furthermore, in this embodiment, the structure enabling the mounting base 310 to slide vertically on the hanging plate 30 is as follows: Vertical slide rails 32 extending vertically are fixedly laid on the hanging plate 30. It is understood that the number of vertical slide rails 32 matches the number of drill bit modules 31, and multiple sets of vertical slide rails 32 are also spaced apart along the first horizontal direction. The mounting base 310 is slidably mounted on the vertical slide rails 32, and the drive mechanism B can drive the mounting base 310 to move up and down on the vertical slide rails 32. Regarding the drive mechanism B, it can preferably be a combination of a motor and a lead screw module, or a linear drive mechanism such as a cylinder. These are conventional techniques in the field of mechanical automation, and therefore will not be described in detail here.

[0045] In this embodiment, the slag suction pipe 313 is positioned next to the drill bit 312 as follows: a cover 314 covering the drill bit 312 is connected to the power output shaft of the motor 311. One end of the slag suction pipe 313 is installed on the cover 314 through a rotary joint, and one end of the slag suction pipe 313 extends into the inner cavity of the cover 314.

[0046] Additionally, it is understood that the other end of the suction pipe 313 is connected to and communicates with an external negative pressure device.

[0047] Next, please refer to the appendix. Figure 1As shown, in this embodiment, the structure that enables multiple drill bit modules 31 to move one-to-one above multiple clamps 20 is as follows: a guide rail 13 extending along the first horizontal direction is fixedly laid on the crossbeam 11, and the hanging plate 30 is slidably disposed on the guide rail 13; the drilling mechanism is also provided with a driving mechanism C, which is disposed on the crossbeam 11 and can drive the hanging plate 30 to move linearly on the guide rail 13. It can be understood that in this embodiment, multiple drill bit modules 31 are first installed on the hanging plate 30 according to the arrangement and spacing of the multiple clamps 20 (that is, the layout and spacing of the vertical slide rails 32 are matched with the arrangement and spacing of the clamps 20), and then the hanging plate 30 is driven to move along the first horizontal direction by the driving mechanism C, thus enabling multiple drill bit modules 31 to correspond one-to-one with multiple clamps 20.

[0048] Furthermore, the drive mechanism C can preferably be a linear motor or a linear drive mechanism such as a "motor and lead screw module combination", which are also conventional technical means in the field of mechanical automation, so they will not be described in detail here.

[0049] Finally, since both the fixture 20 and the workpiece P are placed vertically, this embodiment also specifically optimizes the vertical distance between the crossbeam 11 and the working platform 10. For example, based on production requirements, this embodiment optimizes the vertical distance between the bottom edge of the crossbeam 11 and the upper surface of the working platform 10 to be no less than 500mm. This is an ultra-high stroke range in the machining field, which not only meets the side drilling requirements of various types of workpieces (i.e., the processing requirements when placed vertically), but also reduces the constraints on the stroke of the drill bit module, thereby making the drilling machine's processing range wider.

[0050] Note: The prefixes "first", "second", "third" etc. in the component names in this specification (such as first positioning component, second positioning component, third positioning component, etc.) and the suffixes "A", "B", "C" etc. in the component names (such as drive mechanism A, drive mechanism B, drive mechanism C, etc.) are only for clarity of description and are not intended to limit the scope of implementation of this invention.

[0051] In summary, the drilling machine of the present invention has a novel, simple, and reasonable structure, and can perform drilling on the sides of multiple workpieces at one time. It not only has high production efficiency but also high drilling quality, which well meets production needs.

[0052] Many specific details have been set forth in the foregoing description to provide a thorough understanding of the present invention. However, the above description is merely a preferred embodiment of the present invention, and the present invention can be implemented in many other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed above. Furthermore, any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, using the methods and techniques disclosed above, without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, shall still fall within the protection scope of the present invention.
