DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0035] In the existing operation, the center of the circle is marked with manual tools such as size templates, sample punches, hand hammers, and markers, and then a hole is drilled using a drilling machine. For example, for the insulation car column accessories, the material is a square tube of F40×40×3, with a length of 1760 mm. A total of 20 mm on the center line of the square tube is drilled. 18 holes. The first hole is 30 mm from the end of the square tube, and then a hole is drilled every 400 mm. During the operation, the position of the hole needs to be drawn on the aluminum plate according to the size of the drawing and then the small hole is drilled. Each time the template is placed on the square tube and aligned with one end, the position mark is marked in the small hole with a marking pen. This step sometimes requires two people to complete. After marking the position on the square tube, start drilling. One operator is responsible for drilling and feeding, and the other operator is responsible for aligning the drill bit with the sample punch. This operation requires two people to cooperate tacitly, and it requires three to four people to complete. The labor intensity is high, the efficiency is low, and the relevant size of the hole cannot be guaranteed.

[0036] Based on this, the embodiment of the present disclosure provides a positioning drilling device, which places the part to be drilled on the bearing surface on the positioning substrate, and arranges the positioning mechanism and the drilling mechanism on the positioning substrate at intervals, and the distance between the positioning mechanism and the drilling mechanism is the spacing of multiple holes on the part to be drilled. The positioning bracket of the positioning mechanism is arranged above the bearing surface through the positioning side plate, and the positioning part is movably connected with the positioning bracket. The positioning part is used to determine the relative position of the part to be drilled on the positioning substrate, so as to serve as a reference point for determining the spacing between multiple holes. After the positioning part positions the part with drilling holes, the drill bit drills the part to be drilled through the through hole on the positioning plate of the drilling mechanism, and the through hole on the positioning plate can guide and limit the drilling position of the drill bit. By implementing the technical solution of the present disclosure, the problems of inconsistent sizes of multi-hole equidistant drilling, low work efficiency, and high labor intensity can be solved.

[0037] The positioning drilling device is described in detail below through a specific embodiment:

[0038] Reference Figures 1 to 9 As shown, in a first aspect of the present disclosure, a positioning drilling device is provided, comprising a positioning substrate 1, a positioning mechanism 2 and a drilling mechanism 3. The positioning substrate 1 has a bearing surface for bearing a part to be drilled 100. The positioning mechanism 2 and the drilling mechanism 3 are arranged on the positioning substrate 1 at intervals. The positioning mechanism 2 comprises a positioning bracket 21, a positioning side plate 22 and a positioning portion 23. The positioning bracket 21 is arranged above the bearing surface through the positioning side plate 22. The positioning portion 23 is movably connected to the positioning bracket 21, and the positioning portion 23 is used to determine the relative position of the part to be drilled 100 on the positioning substrate 1; the drilling mechanism 3 has a positioning plate 31 and a drilling side plate 32. The positioning plate 31 is arranged above the bearing surface through the drilling side plate 32, and the positioning plate 31 is provided with a through hole for the drill bit 200 to pass through, and the through hole faces the bearing surface.

[0039] The present disclosure places the to-be-drilled part 100 on the bearing surface of the positioning substrate 1, and arranges the positioning mechanism 2 and the drilling mechanism 3 on the positioning substrate 1 at intervals, and the distance between the positioning mechanism 2 and the drilling mechanism 3 is the spacing between the multiple holes on the to-be-drilled part 100, the positioning bracket 21 of the positioning mechanism 2 is arranged above the bearing surface through the positioning side plate 22, the positioning part 23 is movably connected with the positioning bracket 21, and the positioning part 23 is used to determine the relative position of the to-be-drilled part 100 on the positioning substrate 1, so as to serve as a reference point for determining the spacing between the multiple holes, after the positioning part 23 positions the drilling part, the drill bit 200 drills the to-be-drilled part 100 through the through hole on the positioning plate 31 of the drilling mechanism 3, and the through hole on the positioning plate 31 can guide and limit the drilling position of the drill bit 200. Further, the L-shaped folded plate structure formed by the positioning plate and the drilling side plate 32 is made of, for example, L63×63×8 angle iron to increase the structural strength.

[0040] Specifically, first move the member 100 to be drilled to the bottom of the positioning plate, and drill holes when the member 100 reaches the preset drilling position. After the first hole is drilled, check the diameter, hole spacing, and center distance of the hole. If there is no problem with the size, continue to push the member 100 forward, and wait for the member 100 to reach the positioning point of the positioning mechanism 2 before drilling a second hole. After drilling, check the hole spacing between the first hole and the second hole. If there is no problem, continue to push the member 100 forward, and repeat the previous steps until all the preset multiple holes on the member 100 are drilled.

[0041] In some embodiments, the positioning portion 23 is provided with a connecting member 231 and a positioning member 232, the connecting member 231 is axially connected to the positioning bracket 21, the rotation direction of the connecting member 231 is consistent with the extension direction of the bearing surface, the positioning member 232 is connected to the connecting member 231, and the positioning member 232 has a snap-fit ​​surface and an unlocking surface, the positioning member 232 has a positioning state and an unlocking state, the snap-fit ​​surface contacts the hole wall of the hole in the positioning state; the unlocking surface contacts the hole wall of the hole in the unlocking state.

[0042] In this embodiment, specifically, the drilling member 100 passes through the positioning mechanism 2, such as Figure 6 As shown in the figure, the positioning member 232 slides on the top surface of the square tube while the member to be drilled 100 moves forward. When the positioning member 232 moves to the hole of the member to be drilled 100, as shown in the figure, Figure 8 As shown, the positioning member 232 slides into the hole through the unlocking surface, and then Fig. 9 As shown, after the member 100 to be drilled moves in the opposite direction, the engaging surface of the positioning member 232 contacts the hole wall of the hole, fixing the position of the member 100 to be drilled, which is the base point for determining the hole spacing. If the speed is too fast when the member 100 to be drilled is pushed forward, the positioning member 232 will rush through the already drilled hole. At this time, just pull the member 100 to be drilled back, and the positioning member 232 will slide out of the hole through the unlocking surface, and repeat the above operation. Furthermore, the unlocking surface of the positioning member 232 can be set to an arc surface, so that it is smoother during the sliding process, so that it can fall into the hole better, and it can also improve the unlocking function when unlocking is needed; the engaging surface of the positioning member 232 can be set to a plane, so as to better realize the engaging function.

[0043] In some embodiments, the positioning side plate 22 and the drilling side plate 32 are arranged perpendicular to the positioning substrate 1 , and the plate surfaces of the positioning side plate 22 and the drilling side plate 32 are arranged on the same plane.

[0044] In this embodiment, the positioning side plate 22 and the drilling side plate 32 are arranged perpendicular to the positioning base plate 1, and the plate surfaces are on the same plane, so that one side of the object 100 to be drilled can be pressed against the positioning side plate 22 and the drilling side plate 32 at the same time to determine the straightness requirement during drilling.

[0045] In some embodiments, the positioning mechanism 2 and / or the drilling mechanism 3 are movably connected to the positioning substrate 1 .

[0046] In this embodiment, the positioning mechanism 2 and / or drilling mechanism 3 of the present disclosure are movably linked to the positioning substrate 1. When it is necessary to adjust the hole distance between two holes, it can be achieved by adjusting the relative position of the positioning mechanism 2 and / or drilling mechanism 3. Specifically, the positioning mechanism 2 and / or drilling mechanism 3 can be movably linked by snapping with the positioning substrate, and the distance between multiple snapping positions is set according to actual needs, so as to adjust the hole distance between the holes. The positioning mechanism 2 and / or drilling mechanism 3 can also be linked by a slideway, so as to adjust the positioning mechanism 2 and the drilling mechanism 3. Furthermore, a scale is provided on the bearing surface to determine the distance between the positioning mechanism 2 and the drilling mechanism 3.

[0047] In some embodiments, the distance between the end surface of the drilling side plate 32 close to the positioning mechanism 2 and the vertical extension line of the center point of the through hole is set to 30 mm.

[0048] In this embodiment, the distance between the end surface of the drilling side plate 32 close to the positioning mechanism 2 and the vertical extension line of the center point of the through hole is set to 30 mm, so that the reference of the first hole to be drilled is determined to provide a basis for subsequent drilling.

[0049] In some embodiments, the positioning side plate 22 includes a first side plate 221 and a second side plate 222 , and the first side plate 221 and the second side plate 222 and the positioning bracket 21 form a gantry structure.

[0050] In this embodiment, the positioning side plate 22 includes a first side plate 221 and a second side plate 222. Specifically, the first side plate 221 and the second side plate 222 are respectively arranged on both sides of the bearing surface, and the positioning bracket 21 is arranged between the first side plate 221 and the second side plate 222. It can be understood that in order to enable the member 100 to be drilled to pass through the first side plate 221 and the second side plate 222, the distance between the two should be greater than the width of the member 100 to be drilled. Further, the first side plate 221 and the second side plate 222 are movably connected to the positioning base plate 1, and the first side plate 221 and the second side plate 222 are connected by a telescopic member, which is used to adjust the distance between the first side plate 221 and the second side plate 222 to adapt to members 100 of various sizes to be drilled, and can clamp the member 100 to be drilled by adjusting the distance between the two, and to a certain extent suppress the shaking of the member 100 to be drilled during drilling.

[0051] In some embodiments, a fixing member is also included, which is connected to the positioning substrate 1 and is used to fix the relative position of the part to be drilled and the positioning substrate 1 .
