Description

Technical Field

[0001] This utility model relates to a positioning fixture for a drilling device, specifically, to a combined positioning device for drilling holes in copper busbars. Background Technology

[0002] Currently, a number of drilling machines in use in the workshop (such as older busbar processing machines for punching copper busbars) lack drilling positioning devices. When these drilling machines are needed, taking copper busbar drilling as an example, after receiving the copper busbar material list and processing drawings from the process department, the copper busbar material processing personnel in the electrical control workshop must first draw crosshair positioning lines on the cut copper busbar according to the drawings and using a ruler. Then, they must use a marking tool to punch sample points at the crosshair positioning lines. Finally, based on the sample points, the copper busbar is placed into the drilling pad of the drilling machine to complete the drilling. This positioning drilling method is cumbersome, involves many steps, has low positioning efficiency, and lacks precision, resulting in low drilling accuracy. Replacing the existing drilling machines with new ones equipped with positioning devices would be very costly.

[0003] In the prior art, there are also some technical solutions that equip existing drilling devices with additional drilling positioning fixtures. For example, the copper busbar punching positioning device disclosed in Chinese Utility Model Patent CN202021563652.3 has the problem of applicability. It can only be applied to a small number of drilling devices with special structures and cannot cope with most of the existing drilling devices in the workshop that are not equipped with drilling positioning devices. For example, the copper busbar rapid drilling positioning device disclosed in Chinese Utility Model Patent CN201821152844.8 is a marking tool used to punch sample marks on copper busbars, which has limited improvement on the overall drilling efficiency of the drilling device.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies and improve the problem that some current drilling devices are not equipped with drilling positioning devices. It provides a combined positioning device for drilling copper busbars, which can be installed on most existing drilling devices in the workshop. It is highly applicable, low in cost, can accurately position the holes, and can improve drilling efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a tooling panel, a tooling bracket, and a positioning adjustment assembly. The tooling bracket is used to support and fix the tooling panel at a position flush with the height of the punching pad of the punching device. The tooling panel is provided with an adapter groove, which is used to reduce the gap between the tooling panel and the punching pad. The positioning adjustment assembly includes a first positioning member and a second positioning member, which are slidably disposed on the plane where the tooling panel is located, and the sliding directions of the first positioning member and the second positioning member are perpendicular to each other.

[0007] Based on the above, the second positioning member is provided with an extended abutment, which is located on the side of the second positioning member facing the first positioning member.

[0008] Based on the above, the extended abutment is slidably disposed on the second positioning member, the extended abutment slides along the length direction of the second positioning member, and a fastening member is provided between the extended abutment and the second positioning member.

[0009] Based on the above, the tooling panel is provided with a sliding groove, the first positioning member slides along the sliding groove, and a fastening member is provided between the first positioning member and the tooling panel.

[0010] Based on the above, the tooling panel is provided with a sliding groove or a slide rail, the second positioning member slides along the sliding groove or the slide rail, and a fastening member is provided between the second positioning member and the tooling panel or the slide rail.

[0011] Based on the above, the drilling device further includes a drilling worktable, the drilling pad is fixedly disposed on the drilling worktable, the drilling worktable is provided with a slide rail, the second positioning member slides along the slide rail, and a fastening member is provided between the second positioning member and the slide rail.

[0012] Based on the above, a scale parallel to the sliding groove is embedded on the surface of the tooling panel.

[0013] Based on the above, a scale parallel to the slide rail is embedded on the slide rail.

[0014] Based on the above, the tooling panel is provided with a panel connecting plate, and the tooling bracket is provided with a bracket connecting plate. The panel connecting plate and the bracket connecting plate are used to connect the drilling device.

[0015] Based on the above, the tooling bracket is provided with height-adjustable support feet at the bottom.

[0016] This utility model has substantial features and advancements compared to existing technologies. Specifically, by using a tooling panel and tooling bracket adapted to a drilling device, the tooling panel can be securely mounted on the outside of the drilling pad of the drilling device. It can be mounted on most drilling devices that are currently in normal use in workshops but are not equipped with positioning devices, resulting in strong overall applicability and low cost. By using positioning adjustment components on the tooling panel and the drilling device, the workpiece can be positioned quickly and accurately, which is beneficial for completing the drilling process quickly and accurately.

[0017] Meanwhile, the scheme of installing the first and second positioning components of the positioning adjustment assembly through slide rails and sliding grooves allows for convenient installation of the first and second positioning components on different drilling devices, further enhancing the applicability of this device. By setting an extension stop, interference between the first positioning component and the sliding of the second positioning component can be avoided, increasing overall applicability. The scale facilitates the determination of the zero point of positioning. The panel connecting plate and the bracket connecting plate enhance the stability of the tooling panel and the tooling bracket. The support feet allow for fine adjustment of the height of the tooling panel, further increasing overall applicability. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] Example 1

[0030] like Figures 1-4 As shown, the combined positioning device for copper busbar drilling in this embodiment is adapted to the drilling device and is used to add positioning fixtures to the drilling device. The drilling device in the figure is an example of a turret punching machine of a busbar processing machine. Other drilling devices (including drilling devices and punching devices) are similar to the turret punching machine in the figure. The drilling device as a whole includes a drilling element (drill bit or punching head) and a drilling pad 41. The drilling pad 41 is generally divided into a drilling substrate or a punching lower die base according to the drilling scenario. It is a positioning and support component for drilling and punching processes. Some drilling devices (such as busbar processing machines) include a drilling worktable 42 and a drilling base that supports the drilling pad 41.

[0031] In this embodiment, the combined positioning device for drilling holes in copper busbars includes a tooling panel 10, a tooling bracket 20, and a positioning adjustment component 30.

[0032] Among them, such as Figure 2 , Figure 4 As shown, the tooling panel 10 is used to support the workpiece 50 (such as a copper busbar). The surface of the tooling panel 10 is flush with the surface of the drilling pad 41. The tooling panel 10 is provided with an adapter groove 101 that is adapted to the shape of the drilling pad 41. The adapter groove 101 is used to reduce the gap between the tooling panel 10 and the drilling pad 41. Specifically, the drilling pad 41 is located inside the adapter groove 101 of the tooling panel 10, and the tooling panel 10 is located outside the drilling pad 41. Only a small gap is left between the two, so that the workpiece 50 can be smoothly slid from the tooling panel 10 onto the drilling pad 41. Therefore, when the operator operates, the workpiece 50 can be smoothly moved from the tooling panel 10 to the bottom of the drilling device, which is beneficial for the subsequent positioning and drilling operations.

[0033] like Figure 2 , Figure 4 As shown, the tooling bracket 20 is used to support and fix the tooling panel 10 on the outside of the punching pad 41, and to make the surface of the tooling panel 10 flush with the surface of the punching pad 41, while ensuring that the tooling panel 10 is securely fixed. The overall frame of the tooling bracket 20 is adapted to the shape of the punching device and the tooling panel 10. The tooling bracket 20 can be a bracket with longitudinal beams, transverse beams and support feet. The tooling bracket 20 can be optionally fixed to the punching base of the punching device or the punching worktable 42.

[0034] like Figure 2 , Figure 3As shown, the positioning adjustment assembly 30 is used to position the drilling position of the workpiece 50; the positioning adjustment assembly 30 includes a first positioning member 31 and a second positioning member 32, which are slidably disposed on the plane of the tooling panel 10 (i.e., the plane of the drilling pad 41), and the sliding directions of the first positioning member 31 and the second positioning member 32 are perpendicular to each other; for example, as Figure 1 As shown, the first positioning member 31 is slidably mounted on the tooling panel 10, and the second positioning member 32 is slidably mounted on the drilling worktable 42. The first positioning member 31 and the second positioning member 32 position the workpiece 50 in the X-axis and Y-axis directions, and can also be directly used as a straightedge against the workpiece 50 to position the workpiece 50 at a specific position on the drilling pad 41 to complete the positioning and drilling.

[0035] Taking the use of a busbar processing machine to punch holes in copper busbars as an example, in this embodiment, the initial zero point positions of the first positioning member 31 and the second positioning member 32 are first determined. Then, the displacement distance of the first positioning member 31 and the second positioning member 32 that need to be adjusted is determined according to the copper busbar process drawing. After the first positioning member 31 and the second positioning member 32 are fixed (by the fasteners mentioned below), the worker holds the copper busbar against the first positioning member 31 and the second positioning member 32. Finally, the busbar processing machine is used to complete the punching of the copper busbar.

[0036] In this embodiment, by using the tooling panel 10 and tooling bracket 20 adapted to the drilling device, the tooling panel 10 can be securely mounted on the outside of the drilling pad 41 of the drilling device. This is applicable to most drilling devices that are not equipped with positioning devices and can be used normally in workshops. It has strong overall applicability and low cost. By using the positioning adjustment component 30 on the tooling panel 10 and the drilling device, the workpiece 50 can be positioned quickly and accurately, which is conducive to completing the drilling process quickly and accurately.

[0037] Example 2

[0038] In this embodiment, the positioning adjustment assembly 30 further includes an extension abutment 33, which is disposed on the second positioning member 32 and on the side of the second positioning member 32 facing the first positioning member 31. Thus, the second positioning member 32 is no longer used as a straightedge, and the extension abutment 33 extends towards the first positioning member 31 as a positioning extension of the second positioning member 32, thereby increasing the positioning adjustment range of the second positioning member 32 relative to the workpiece 50.

[0039] In this embodiment, the perpendicular sliding relationship between the first positioning member 31 and the second positioning member 32 will generate a sliding range in which the two interfere with each other. Within this mutually interfering sliding range, the workpiece 50 cannot be effectively positioned. Extending the abutment member 33 effectively avoids this situation.

[0040] Preferably, the extension abutment 33 is slidably disposed on the second positioning member 32, and the extension abutment 33 slides along the length direction of the second positioning member 32. A fastening member is provided between the extension abutment 33 and the second positioning member 32 to loosen or lock the extension abutment 33, so that the extension abutment 33 can be fixed on the second positioning member 32. The fastening member can be an adjustable fastening handle, such as a quick release handle or a fine adjustment handle.

[0041] Specifically, one end of the extended abutment 33 is a third slide block 331, which is slidably disposed on the second limiting member 32. The third slide block 331 is provided with a locking member to loosen or lock the third slide block 331, so that the third slide block 331 can slide or be fixed on the second positioning member 32. Preferably, the length extension direction of the extended abutment 33 is perpendicular to the length extension direction of the second limiting member 32. The sliding extended abutment 33 further improves the positioning adjustment range of the second positioning member 32 for the workpiece 50, and avoids the situation where interference occurs between the first positioning member 31 and the second positioning member 32, resulting in ineffective positioning.

[0042] Example 3

[0043] In this embodiment, as Figures 1-4 As shown, the first positioning member 31 is disposed on the tooling panel 10, and the second positioning member 32 is disposed on the drilling worktable 42; this embodiment is applicable to drilling equipment equipped with a drilling worktable 42.

[0044] In this embodiment, the first positioning member 31 abuts against the long side of the workpiece 50, serving as a long side guide for the workpiece 50; the second positioning member 32 abuts directly or indirectly against the short side of the workpiece 50, serving as a short side guide for the workpiece 50. The second positioning member 32 can indirectly abut against the workpiece 50 through the extended abutment 33 in the above embodiment 2. The first positioning member 31 and the second positioning member 32 complete the positioning of the workpiece 50 from two mutually perpendicular directions. Therefore, the first positioning member 31 generally requires a smaller positioning adjustment distance (i.e., sliding distance) than the second positioning member 32, and the length of the first positioning member 31 is generally greater than the length of the second positioning member 32.

[0045] In this embodiment, the drilling device includes a drilling worktable 42, a first positioning member 31 slidably disposed on the tooling panel 10, and a second positioning member 32 slidably disposed on the drilling worktable 42. Thus, since the adjustment distance of the first positioning member 31 is generally smaller than that of the second positioning member 32, the tooling panel 10 of the drilling device can have a smaller surface area, which is beneficial to reduce the space occupied by the tooling panel 10 and the tooling bracket 20 and save costs.

[0046] In this embodiment, the tooling panel 10 is provided with a sliding groove 102. The sliding groove 102 can be a through groove or a blind groove. The first positioning member 31 slides along the sliding groove 102. The first positioning member 31 is fixed to the tooling panel 10 by the sliding groove 102 and a fastener. The fastener can be an adjustable fastening handle, such as a quick-release handle or a fine-tuning handle. For example, the first positioning member 31 can be provided with a slider that slides in the sliding groove 102. The fastener can be fixed to the slider so that the first positioning member 31 is fixed at a specific position in the sliding groove 102. Therefore, fixing the first positioning member 31 at a specific position on the tooling panel 10 completes the positioning of the first positioning member 31.

[0047] The first positioning member 31 is slidably positioned by the sliding groove, so that there is no need to set protruding parts on the surface of the tooling panel 10. The first positioning member 31 will not be interfered with when it is displaced on the surface of the tooling bracket 20. Within the sliding distance of the first positioning member 31, the first positioning member 31 can be used as a guide for the workpiece 50 and fit closely against the long side of the workpiece 50.

[0048] In this embodiment, a slide rail 322 is provided on the drilling workbench 42. The slide rail 322 is fixed on the drilling workbench 42 by fasteners such as countersunk bolts. The second positioning member 32 slides on the slide rail 322. A fastening member is provided between the second positioning member 32 and the slide rail 322. The fastening member can be an adjustable fastening handle, such as a quick-release handle or a fine-tuning handle. For example, the end of the second positioning member 32 is provided with a second slide block 321. The second slide block 321 slides on the slide rail 322. The second slide block 321 is provided with a fastening member to loosen or lock the second slide block 321, so that the second positioning member 32 can slide or be fixed on the second positioning member 32. Therefore, the second positioning member 32 is fixed at a specific position on the drilling workbench 42, thus completing the positioning of the second positioning member 32.

[0049] The existing drilling device can be easily modified by using the slide rail 322, and a second positioning component 32 can be added to the existing drilling device. The second positioning component 32 on the drilling worktable 42 cooperates with the first positioning component 31 on the tooling panel 10 to complete the positioning of the workpiece 50.

[0050] Example 4

[0051] The difference between this embodiment and embodiment 3 is that the second positioning element 32 is also set on the tooling panel 10; this embodiment is applicable to drilling equipment that does not have a drilling worktable 42 and only has a drilling base 41.

[0052] In this embodiment, the tooling panel 10 is provided with a sliding groove 102 for the first positioning member 31 to slide, and the tooling panel 10 is provided with a slide rail 322 for the second positioning member 32 to slide. The slide rail 322 in this embodiment is similar to the slide rail 322 in embodiment 3, and will not be described again.

[0053] In this embodiment, the tooling panel 10 can be two panels, which are respectively disposed on both sides of the punching device; the tooling panel 10 can also be a single panel, with the sliding groove 102 of the first positioning member 31 and the slide rail 322 of the second positioning member 32 disposed on both sides of the punching device.

[0054] Example 5

[0055] The difference between this embodiment and embodiment 4 is that the second positioning member 32 is also set in the sliding groove 102 on the tooling panel 10; the opening position of the sliding groove 102 of the second positioning member 32 is similar to the fixed position of the slide rail 322 in embodiment 3, and the function of the sliding groove 102 of the second positioning member 32 is similar to that of the sliding groove 101 of the first positioning member 32 in embodiment 3, which will not be described again.

[0056] Example 6

[0057] In this embodiment, the positioning adjustment component 30 further includes a scale, with two scales parallel to the first positioning member 31 and the second positioning member 32, respectively; based on embodiment 3, one of the scales is embedded in one side of the sliding groove 102 of the first positioning member 31 on the tooling panel 10 (e.g., Figure 4 As shown), another ruler is embedded in the slide rail 322 of the second positioning member 31 on the punching workbench 42; based on embodiment 4, one ruler is embedded in one side of the sliding groove 102 of the first positioning member 31 on the tooling panel 10, and the other ruler is embedded in the slide rail 322 of the second positioning member 31 on the tooling panel 10, or on the tooling panel 10 on one side of the slide rail 322; based on embodiment 5, one ruler is embedded in one side of the sliding groove 102 of the first positioning member 31 on the tooling panel 10, and the other ruler is embedded in one side of the sliding groove 102 of the second positioning member 31 on the tooling panel 10.

[0058] In this embodiment, the scale is embedded in the sliding groove 102 of the tooling panel 10 or in the track 322, so that the scale is integrated with the tooling panel 10 or the positioning adjustment component 30. This makes it convenient to determine the installation position of each component and the zero point position of positioning when the tooling panel 10, tooling bracket 20 and positioning adjustment component 30 of this device are added to the drilling device.

[0059] Example 7

[0060] In this embodiment, as Figure 2 , Figure 4As shown, the tooling panel 10 is provided with a panel connecting plate 11, and the tooling bracket 20 is provided with a bracket connecting plate 21. The panel connecting plate 11 and the bracket connecting plate 21 are used to connect the drilling device to enhance the stability of the tooling panel 10 and the tooling bracket 20. For example, based on embodiment 3, the panel connecting plate 11 and the bracket connecting plate 21 are used to connect the tooling panel 10 and the tooling bracket 20 to the drilling worktable 42 of the drilling device. For example, based on embodiments 4 and 5, the panel connecting plate 11 is used to connect the tooling panel 10 to the drilling pad 41, and the bracket connecting plate 21 is used to connect the tooling bracket 20 to the drilling base for supporting the drilling pad 41.

[0061] Example 8

[0062] In this embodiment, as Figure 2 , Figure 4 As shown, the tooling bracket 20 has adjustable support feet 22 at the bottom to facilitate fine adjustment of the height of the tooling panel 10 so that the height of the tooling panel 10 is flush with the height of the drilling pad 41.

[0063] Based on the above embodiments, the combined positioning device for drilling copper busbars of this utility model, by using the tooling panel 10 adapted to the drilling device and the tooling bracket 20, can securely mount the tooling panel 10 on the outside of the drilling pad 41 of the drilling device. It can be mounted on most drilling devices that are currently in normal use in workshops but are not equipped with positioning devices. It has strong overall applicability and low cost. By using the positioning adjustment component 30 on the tooling panel 10 and the drilling device, the positioning of the workpiece 50 can be completed quickly and accurately, which is conducive to completing the drilling process quickly and accurately. The scheme of installing the first positioning member 31 and the second positioning member 32 of the positioning adjustment assembly 30 through the slide rail 322 and the sliding groove 102 can conveniently install the first positioning member 31 and the second positioning member 32 on different drilling devices, further improving the applicability of this device; by setting the extension abutment 33, interference of the first positioning member 31 on the sliding of the second positioning member 32 can be avoided; the scale makes it easy to determine the zero point position of the positioning; the panel connecting plate 11 and the bracket connecting plate 21 can enhance the stability of the tooling panel 10 and the tooling bracket 20; the support foot 22 can finely adjust the height of the tooling panel 10.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
