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

[0031] Example 1:

[0032] Please see the attached Figure 1 To the attached Figure 6 As shown, this embodiment 1 provides a drilling machine for side processing of a workpiece, comprising a base 1, a fixture mechanism and a drilling mechanism, wherein the base 1 is provided with a working platform 10 and a crossbeam 11 fixedly mounted above the working platform 10 by a column, and the area on the working platform 10 and below the crossbeam 11 is defined as a drilling processing station; the fixture mechanism is provided with a plurality of fixtures 20, and the plurality of fixtures 20 are spaced apart along a first horizontal direction on the working platform 10, and the plurality of fixtures 20 can also be spaced apart along the first horizontal direction with the plurality of fixtures 20. A second horizontal direction perpendicular to the first horizontal direction performs synchronous reciprocating motion to approach or move away from the drilling processing station; in addition, each of the fixtures 20 can fix the workpiece P thereon in a vertical manner; the drilling mechanism is provided with a hanging plate 30 arranged on the beam 11 and a plurality of drill modules 31 arranged on the hanging plate 30 at intervals along the first horizontal direction, and the plurality of drill modules 31 can be moved one by one to the top of the plurality of fixtures 20 to perform drilling processing on the side of the workpiece P vertically arranged on the fixture 20.

[0033] From the above, it can be seen that compared with the existing technology, the clamp in the drilling machine described in this embodiment can firmly fix the workpiece thereon in a vertical manner, so that the drill bit module can very easily drill the side of the workpiece, with high drilling efficiency and high drilling quality; moreover, the drilling machine described in this embodiment is also equipped with multiple clamps and multiple drill bit modules, which can realize drilling of multiple workpieces at one time, greatly improving production efficiency, thereby being able to well meet production needs.

[0034] The specific structure of the drilling machine for side processing of a workpiece described in this embodiment is described in detail below.

[0035] First, please refer to the attached Figure 1 To the attached Figure 5 As shown, the preferred implementation structure of the fixture 20 in this embodiment is: the fixture 20 is provided with a vertically placed fixture body 200 and a positioning component arranged on the fixture body 200 and capable of fixing the workpiece P on the fixture body 200 in a vertical manner.

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

[0037] Furthermore, the positioning assembly includes a plurality of first positioning members 201, a second positioning member 202, and a third positioning member 203, wherein the plurality of first positioning members 201 are spaced apart on the bottom side of the receiving facade 2000 to support the workpiece; the plurality of second positioning members 202 are symmetrically arranged on the two opposite sides of the receiving facade 2000 to elastically clamp and position the workpiece; the plurality of third positioning members 203 are spaced apart on the receiving facade 2000 to adsorb and position the workpiece; for details, please refer to the attached Figure 3 and attached Figure 5 As can be understood, the positioning assembly can securely and stably 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-to-back direction (specifically provided by the second positioning member 202), and an adsorption force (specifically provided by the third positioning member 203) to the workpiece P.

[0038] Furthermore, the first positioning member 201 can preferably be a positioning block or a positioning pin; the second positioning member 202 can preferably be an elastic clamping block; and the third positioning member 203 can preferably be a vacuum nozzle. The implementation structure of the elastic clamping block can be as follows: Figure 4 As shown, the elastic clamping block is provided with a U-shaped block 2020 and an elastic block 2021 connected to the inner surface of the groove bottom of the U-shaped block 2020 through a spring, and one end of the elastic block 2021 can extend out of the groove body of the U-shaped block 2020. Figure 4 The elastic clamping block structure shown is only a preferred embodiment, and this embodiment does not impose any restrictions on it.

[0039] Furthermore, in order to better enhance the limiting positioning function of the positioning component on the workpiece P, so as to better enhance the drilling processing quality, in this embodiment, the positioning component further includes at least one latch 204 and a plurality of limit pins 205, which can be further referred to in the attached drawings. Figure 3 and attached Figure 5 As shown, at least one of the pins 204 is arranged on the receiving vertical surface 2000 and can be plugged into and matched with the socket on the workpiece P, that is, the pin 204 is used for hanging and positioning the workpiece P; multiple limit pins 205 are arranged at intervals on the two opposite sides of the receiving vertical surface 2000 to limit the workpiece P, that is, the limit pins 205 assist the second positioning member 202 to firmly limit and position the front and rear directions of the workpiece P.

[0040] Please continue to refer to the attached Figure 1 and attached Figure 2 As shown, in this embodiment, the implementation structure for realizing that multiple clamps 20 can perform synchronous reciprocating motion along the second horizontal direction is: a slide rail 12 extending along the second horizontal direction is fixedly laid on the working platform 10; the clamp mechanism is also provided with a slide 21 slidably set on the slide rail 12 through a slider and a driving mechanism A22 set on the working platform 10 and capable of driving the slide 21 to perform linear motion on the slide rail 12, and multiple clamps 20 are arranged on the slide 21 at intervals and in parallel along the first horizontal direction.

[0041] Furthermore, the driving mechanism A22 may preferably adopt a linear motor, or a linear driving mechanism such as a "motor and screw module combination", which is a conventional technical means in the field of mechanical automation, so it will not be described in detail here.

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

[0043] Then, please refer to the attached Figure 1 and attached Figure 6As shown, the drill module 31 in this embodiment preferably adopts the following implementation structure: the drill module 31 is provided with a mounting seat 310 which is arranged on the hanging plate 30 and can slide vertically, a driving mechanism B which is arranged on the hanging plate 30 and can drive the mounting seat 310 to move up and down, a motor 311 arranged on the mounting seat 310, a drill bit 312 connected to the power output shaft of the motor 311, and a slag suction pipe 313 which is arranged next to the drill bit 312 and connected to an external negative pressure device. It can be understood that in the drill module 31, the driving 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, and the motor 311 can drive the drill bit 312 to rotate, that is: the driving mechanism B can cooperate with the motor 311 to enable the drill bit 312 to drill the workpiece P; the slag suction pipe 313 can suck away the waste chips generated during the drilling process, which not only effectively improves the processing environment, but also saves the cutting fluid conventionally used in the prior art (that is, saves consumables) and saves manpower for cleaning the cutting fluid.

[0044] Furthermore, in this embodiment, the structure for enabling the mounting seat 310 to slide vertically on the hanging plate 30 is as follows: a vertical slide rail 32 extending vertically is fixedly laid on the hanging plate 30. It is understandable that the number of the vertical slide rails 32 matches the number of the drill modules 31, and multiple groups of the vertical slide rails 32 are also spaced apart along the first horizontal direction; the mounting seat 310 is slidably disposed on the vertical slide rail 32, and the drive mechanism B is capable of driving the mounting seat 310 to move up and down on the vertical slide rail 32. As for the drive mechanism B, it can preferably adopt a "motor and screw module combination" or a linear drive mechanism such as a cylinder, which is also a conventional technical means in the field of mechanical automation and will not be described in detail here.

[0045] The implementation structure of this embodiment in which the slag suction pipe 313 is arranged next to the drill bit 312 is as follows: a cover shell 314 is connected to the power output shaft of the motor 311 and is arranged outside the drill bit 312. One end of the slag suction pipe 313 is installed on the cover shell 314 through a rotary joint. At the same time, one end of the slag suction pipe 313 also extends into the inner cavity of the cover shell 314.

[0046] In addition, it is understandable that the other end of the slag suction pipe 313 is connected to and communicated with an external negative pressure device.

[0047] Then, please refer to the attached Figure 1As shown, in this embodiment, the structure for achieving one-to-one correspondence between the plurality of drill modules 31 and the plurality of fixtures 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 arranged on the guide rail 13; the drilling mechanism is further provided with a driving mechanism C, which is arranged on the crossbeam 11 and is capable of driving the hanging plate 30 to perform linear motion on the guide rail 13. It can be understood that in this embodiment, the plurality of drill modules 31 are first installed on the hanging plate 30 according to the arrangement and spacing of the plurality of fixtures 20 (that is, the arrangement and spacing of the vertical slide rails 32 respectively match the arrangement and spacing of the fixtures 20), and then the hanging plate 30 is driven by the driving mechanism C to move along the first horizontal direction, thereby achieving one-to-one correspondence between the plurality of drill modules 31 and the plurality of fixtures 20.

[0048] Furthermore, the driving mechanism C may preferably adopt a linear motor, or a linear driving mechanism such as a "motor and screw module combination", which is also a conventional technical means in the field of mechanical automation, so it will not be described in detail here.

[0049] Finally, given that the fixture 20 and workpiece P are both positioned vertically, this embodiment specifically optimizes the vertical distance between the crossbeam 11 and the work 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 work platform 10 to no less than 500 mm. This represents an ultra-high travel range in machining, meeting the requirements for side drilling of various workpiece types (i.e., when placed vertically) while also reducing the travel restrictions of the drill module, thereby extending the machining range of the drilling machine.

[0050] Note: In this specification, the prefixes "first", "second", "third", etc. of the component names (such as the first positioning member, the second positioning member, the third positioning member, etc.) and the suffixes "A", "B", "C", etc. of the component names (such as drive mechanism A, drive mechanism B, drive mechanism C, etc.) are only for the convenience of description and are not used to limit the scope of implementation of this utility model patent.

[0051] To sum up, the drilling machine described in the utility model has a novel, simple and reasonable structure, and can realize drilling processing on multiple workpiece sides at one time. It not only has high production efficiency but also high drilling quality, which well meets production needs.

[0052] In the above description, many specific details are set forth in order to fully understand the present invention. However, the above description is only a preferred embodiment of the present invention. The present invention can be implemented in many other ways different from those described herein, so the present invention is not limited by the specific implementation disclosed above. At the same time, any person skilled in the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
