Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a drilling machine. 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, drilling machines often have the following drawbacks when used for drilling workpieces: ① 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 sides), and cannot effectively drill on the sides. ② Existing drilling machines mostly 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. ③ Existing drilling machines often use spray cutting fluid to collect waste chips, but spraying cutting fluid not only causes significant pollution to the processing environment but also requires manpower for timely equipment cleaning, leading to high production costs.

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

[0005] To overcome the above-mentioned defects, the present invention provides a drilling machine with a novel, simple and reasonable structure.

[0017] As a further improvement of the present invention, the plurality of mounting sections are flush with one side of the slide plate along the first horizontal direction, or the plurality of mounting sections extend beyond one side of the slide plate along the first horizontal direction.

[0018] In addition, an abutment block for abutting the fixture is positioned below each of the mounting sections, and a sensor for sensing the workpiece is provided next to each of the mounting sections.

[0019] As a further improvement of the present invention, the drilling machine further includes a base and a drive mechanism A.

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please see the appendix Figure 1 To be continued Figure 6As shown, this embodiment 1 provides a drilling machine, which mainly includes a fixture device 1 and a drilling device. The fixture device 1 is provided with a mounting member 10 that can reciprocate along a first horizontal direction (such as the "front-back direction") and a plurality of fixtures 11 arranged side by side on the mounting member 10 along a second horizontal direction (such as the "left-right direction") perpendicular to the first horizontal direction. Each fixture 11 can fix the workpiece vertically on the fixture 11 alone or in cooperation with the mounting member 10. The drilling device is provided with a plurality of drill bit modules 20 that are also arranged side by side along the second horizontal direction. The plurality of drill bit modules 20 can be moved one by one above the plurality of fixtures 11 to drill holes in the side of the workpiece vertically arranged on the fixture 11. Each drill bit module 20 can also collect waste material in a negative pressure manner.

[0038] As can be seen from the above, compared with the prior art, the drilling machine of this embodiment has the following advantages: ① The fixture device can securely fix the workpiece vertically on it, thereby enabling the drill bit module in the drilling device to easily drill the side of the workpiece, resulting in high drilling efficiency and high drilling quality. ② The drilling machine is equipped with multiple fixtures and multiple drill bit modules, which can perform drilling on multiple workpieces at one time, greatly improving production efficiency and well meeting production needs. ③ The drill bit module collects waste materials (such as chips generated during drilling) using negative pressure, which effectively improves the processing environment, eliminates the need for conventional cutting fluid (i.e., saves consumables), and saves manpower for cleaning the cutting fluid, thus greatly reducing production costs.

[0039] The specific structure of the drilling machine described in this embodiment will be described in detail below.

[0040] First, please continue to refer to the appendix. Figure 1 To be continued Figure 5 As shown, the preferred implementation structure of the fixture device 1 in this embodiment is as follows: the mounting member 10 is provided with a sliding plate 100, a mounting frame 101 vertically and fixedly disposed on the upper side of the sliding plate 100, and a plurality of partitions 102 spaced apart along the second horizontal direction on one upright side (e.g., the "front upright side") of the mounting frame 101, and the plurality of partitions 102 further divide one upright side of the mounting frame 101 into a plurality of mounting sections 1010; a plurality of fixtures 11 are installed one-to-one on the plurality of mounting sections 1010, and each fixture 11 cooperates with its corresponding partition 102 to receive and fix the vertically placed workpiece. That is, in this embodiment, the workpiece is fixed vertically on the fixture 11 by the cooperation of the fixture 11 and the mounting member 10.

[0041] Regarding the separator 102, the preferred implementation structure in this embodiment is as follows: Please refer to the appendix. Figure 4 As shown, the separator 102 includes at least two dividing blocks 1020 arranged side by side along the vertical direction on one upright side of the mounting bracket 101. It is understood that the dividing blocks 1020 enable the separator 102 to have both dividing and workpiece-stopping / positioning functions, while also being simple in structure, easy to assemble, and low in production cost.

[0042] Furthermore, in this embodiment, a magnetic block is embedded in the dividing block 1020, so that the dividing block 1020 / the dividing member 102 also has the function of magnetically locating the workpiece, further improving the effect of restricting and fixing the workpiece.

[0043] Furthermore, in this embodiment, the number of the segmented blocks 1020 located in different separators 102 may be the same or different. For example, please refer to the appendix. Figure 3 and attached Figure 4 As shown, if the first horizontal direction is defined as the front-to-back direction and the second horizontal direction as the left-to-right direction, each of the two leftmost and rightmost separators 102 has two dividing blocks 1020, while each of the other separators 102 in the middle has three dividing blocks 1020. Of course, this embodiment does not impose any restrictions on the number, shape, or size of the dividing blocks 1020; the specific requirements will be determined based on the processing needs.

[0044] Regarding the fixture 11, the preferred implementation structure in this embodiment is as follows: Please refer to the appendix. Figure 5 As shown, the fixture 11 is provided with a fixture body 110 that is detachably fixed to the mounting section 1010 by fasteners (such as screws) and a positioning component disposed on the fixture body 110 that can limit and position the workpiece.

[0045] Furthermore, the fixture body 110 is provided with a receiving surface 1100 for the workpiece to abut; the positioning assembly includes multiple first positioning elements 111, second positioning elements 112, and third positioning elements 113, wherein the multiple first positioning elements 111 are spaced apart on the bottom side of the receiving surface 1100 to support the workpiece; the multiple second positioning elements 112 and the multiple third positioning elements 113 are spaced apart on the receiving surface 1100, and the second positioning elements 112 can insert and position the workpiece (understandably, the second positioning elements 112 are used to insert and cooperate with the holes on the workpiece), and the third positioning elements 113 can adsorb and position the workpiece.

[0046] Understandably, by providing upward support force (specifically provided by the first positioning member 111), adsorption force (specifically provided by the third positioning member 113), and insertion restriction function (specifically provided by the second positioning member 112) to the workpiece through the positioning component, combined with the left and right stop restriction function and magnetic attraction force provided by the separator 102 to the workpiece, the workpiece can be reliably and stably fixed on the fixture body 110.

[0047] Furthermore, the fixture body 110 has a plate-like structure, and one side of the fixture body 110 along the first horizontal direction is the receiving surface 1100; it is understood that, by attaching Figure 1 It can be seen that the front facade of the fixture body 110 is the receiving facade 1100.

[0048] The first positioning element 111 is a positioning block or a positioning pin; the second positioning element 112 is a pin; and the third positioning element 113 is a vacuum nozzle.

[0049] Furthermore, in the mounting component 10 structure described in this embodiment, the mounting bracket 101 extends linearly along the second horizontal direction, and the plurality of mounting sections 1010 are all flush with one side (e.g., the "front side") of the slide plate 100 along the first horizontal direction (see Appendix). Figure 3 and attached Figure 4 As shown), or multiple mounting sections 1010 may extend beyond one side of the slide plate 100 along the first horizontal direction. Based on the above arrangement of the mounting sections 1010, this embodiment also provides an abutment block 103 positioned below each mounting section 1010 for abutting the fixture 11, so as to provide support, restriction, etc.; and a sensor 12 for sensing the workpiece is provided next to each mounting section 1010 for detection and error prevention.

[0050] Understandably, when the mounting section 1010 is aligned with one side (e.g., the "front side") of the slide plate 100 along the first horizontal direction, the abutment block 103 can be fixedly connected to the lower side of the slide plate 100 (see attached diagram). Figure 3 and attached Figure 4 (as shown); and when the mounting section 1010 extends outside the side of the slide plate 100 along the first horizontal direction, the abutment block 103 can be fixedly connected to the lower side of the mounting section 1010.

[0051] Furthermore, in the fixture device 1 described in this embodiment, the structure that enables the mounting member 10 to reciprocate along the first horizontal direction is as follows: Please refer to the appendix. Figure 1 and attached Figure 2As shown, the drilling machine also includes a base 3 and a drive mechanism A. A slide rail A30 extending along the first horizontal direction is fixedly laid on the top side of the base 3. The slide plate 100 of the mounting member 10 is slidably connected to the slide rail A30. The drive mechanism A can drive the slide plate 100 to move linearly on the slide rail A30.

[0052] Furthermore, the drive mechanism A can preferably be a linear motor or a linear drive mechanism such as a "motor and lead screw module combination". This is a conventional technical means in the field of mechanical automation, so it will not be described in detail here.

[0053] Next, please refer to the appendix. Figure 1 and attached Figure 6 As shown, the preferred implementation structure of the drilling device in this embodiment is as follows: the drilling machine further includes a crossbeam 4 fixedly mounted above the machine base 3 and a hanging plate 5 that can slide along the second horizontal direction on the crossbeam 4, and the hanging plate 5 is also located above the slide plate 100 (that is, there is a gap between the hanging plate 5 and the slide plate 100 to allow the slide plate 100 to move freely); a plurality of drill bit modules 20 are arranged side by side on the hanging plate 5 along the second horizontal direction. Specifically, each drill bit module 20 is provided with a mounting base 200 that can slide vertically on the hanging plate 5, a drive mechanism B that is mounted on the hanging plate 5 and can drive the mounting base 200 to move up and down, a motor 201 mounted on the mounting base 200, a drill bit 202 connected to the power output shaft of the motor 201, and a slag suction pipe 203 that is located next to the drill bit 202 and connected to an external negative pressure device. Understandably, ① in this embodiment, multiple drill bit modules 20 are first installed on the hanging plate 5 according to the layout and spacing of the multiple fixtures 11, and then the hanging plate 5 is driven to move along the second horizontal direction, so that the multiple drill bit modules 20 can be moved one-to-one above the multiple fixtures 11. ② In the drill bit module 20, the driving mechanism B can drive the mounting base 200, the motor 201, the drill bit 202 and the slag suction pipe 203 to move up and down together, and the motor 201 can drive the drill bit 202 to rotate. That is, the driving mechanism B and the motor 201 cooperate to drive the drill bit 202 to drill holes in the workpiece. The slag suction pipe 203 uses negative pressure to suck away the waste generated during drilling, which effectively ensures the cleanliness of the processing environment.

[0054] Furthermore, the specific structure by which the hanging plate 5 can be slidably mounted on the crossbeam 4 along the second horizontal direction in this embodiment is as follows: Please refer to the appendix. Figure 1As shown, a slide rail B40 extending along the second horizontal direction is fixedly laid on the crossbeam 4, and the hanging plate 5 is slidably connected to the slide rail B40. The drilling machine also includes a drive mechanism C, which is disposed on the crossbeam 4 and can drive the hanging plate 5 to move linearly on the slide rail B40. 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 is a conventional technical means in the field of mechanical automation and will not be described in detail here.

[0055] In this embodiment, the structure that enables the mounting base 200 to slide vertically on the hanging plate 5 is as follows: Please refer to the appendix. Figure 1 As shown, multiple sets of vertically extending slide rails C50 are fixedly laid on the hanging plate 5. These slide rails C50 are spaced apart along the second horizontal direction and are slidably connected to the mounting seats 200 in the multiple sets of drill bit modules 20. As can be seen from the above, the drive mechanism B can drive the mounting seats 200 to move up and down on the slide rails C50. Regarding the drive mechanism B, it can preferably be a "motor and lead screw module combination" or a linear drive mechanism such as a cylinder, which is a conventional technical means in the field of mechanical automation, and therefore will not be described in detail here.

[0056] In this embodiment, the structure in which the slag suction pipe 203 is positioned next to the drill bit 202 and connected to an external negative pressure device is as follows: Please refer to the attached diagram. Figure 6 As shown, a cover 204 covering the drill bit 202 is also connected to the power output shaft of the motor 201. One end of the slag suction pipe 203 is installed on the cover 204 through a rotary joint, and one end of the slag suction pipe 203 extends into the inner cavity of the cover 204. The other end of the slag suction pipe 203 is connected to and communicates with an external negative pressure device.

[0057] Note: The prefixes "first", "second", "third" etc. of 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. of the component names (such as slide rail A, slide rail B, slide rail C, etc.) are only for ease of description and are not intended to limit the scope of implementation of this invention patent.

[0058] In summary, the drilling machine of the present invention has a novel, simple, and reasonable structure. It can not only perform side drilling on multiple workpieces at one time with high drilling efficiency and high drilling quality, but also collect waste material in a negative pressure manner, which effectively improves the processing environment and greatly saves production costs, thus well meeting market demand.

[0059] 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.
