Description

Technical Field

[0001] This application relates to the technical field of power auxiliary appliances, and in particular to a four-hole wire clamp hole spacing positioner. Background Technology

[0002] In the field of power system substation maintenance, the hole spacing accuracy of four-hole clamps directly determines the reliability of electrical connections and equipment lifespan.

[0003] However, the existing technology relies on manual positioning, and the error of manual positioning is generally ≥±1.5mm, which far exceeds the State Grid maintenance standard (≤±0.2mm). This results in 23% of wire clamp contact failures, and 18% of GIS equipment failures are caused by hole spacing deviations. A single failure causes an average economic loss of 120,000 yuan.

[0004] Drilling a single set of wire clamps takes 15 minutes; in batch operations, the rework rate exceeds 20%, and the cost of a single rework exceeds 5,000 yuan (including equipment downtime losses). In a 220kV substation renovation project, it takes 5 people working together for 4 hours to complete drilling 24 wire clamps using traditional methods.

[0005] It is evident that traditional processing methods that rely on manual scribing and positioning, as well as measurement with general measuring tools, have poor accuracy and low efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this application provides a four-hole wire clamp hole spacing positioner. In this embodiment, a pre-made positioning device is used. After the operator fixes the plate onto the wire clamp, the pre-made reference positioning holes on the plate can provide position guidance for the operator, enabling the operator to quickly and accurately complete the wire clamp drilling operation.

[0007] The above-mentioned objective of this application is achieved through the following technical solution:

[0008] A four-hole wire clamp hole spacing positioner includes a plate and two clamps;

[0009] One side of the plate is the mating surface for the wire clamp. Four reference positioning holes are provided on the plate. The four reference positioning holes are rectangularly distributed in the middle of the plate. The center point of the opening of the four reference positioning holes on the mating surface of the plate is located at the four vertices of the same virtual rectangle, which is located on the mating surface.

[0010] Two clamps are movably connected to one side of the mating surface of the board. The position of the clamps relative to the board is adjustable. The clamps are equipped with a locking mechanism to fix the position of the clamps relative to the board. When the mating surface is in contact with the wire clamp, the two clamps move closer to each other to clamp the wire clamp. After the locking mechanism locks the position of the clamps, the position of the board relative to the wire clamp is fixed.

[0017] A threaded hole is provided on one side of the fixture. The locking mechanism includes a locking bolt. The stud of the locking bolt can form a threaded connection with the threaded hole. When the stud of the locking bolt forms a threaded connection with the threaded hole, the head of the locking bolt can form a friction pair with the side of the plate away from the contact surface, thereby fixing the position of the fixture and the plate.

[0018] Optionally, a set of slides includes two parallel slides, the fixture has two threaded holes, and the number of locking bolts that can be detachably connected to the same fixture is two.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application provides a four-hole wire clamp hole spacing positioner, including a steel plate 10 and two clamps 20 that are independent of the plate 10.

[0035] One side of the plate 10 is the mating surface 11 for the wire clamp. The mating surface 11 is flat and smooth. Four reference positioning holes 12 are provided on the plate 10. The central axis of the reference positioning holes 12 is parallel to the normal vector of the mating surface 11. The four reference positioning holes 12 are rectangularly distributed in the middle of the plate 10. The center point of the opening of the four reference positioning holes 12 on the mating surface 11 of the plate 10 is located at the four vertices of the same virtual rectangle. The virtual rectangle is located on the mating surface 11.

[0036] Two clamps 20 are movably connected to one side of the mating surface 11 of the plate 10. The position of the clamps 20 relative to the plate 10 is adjustable. A locking mechanism 30 is installed on the clamps 20 to fix the position of the clamps 20 relative to the plate 10. When the mating surface 11 is in contact with the wire clamp, the two clamps 20 move closer to each other to clamp the wire clamp. After the locking mechanism 30 locks the position of the clamps 20, the position of the plate 10 relative to the wire clamp is fixed.

[0037] The following section will provide further details based on specific usage scenarios.

[0038] In use, the operator attaches the wire clamp to the mating surface 11 of the plate 10, uses the clamp 20 to hold the plate 10 in place, and then uses the locking mechanism 30 to fix the positional relationship between the two clamps 20 and the plate 10, thereby fixing the entire positioner on the wire clamp.

[0039] The operator then flips the wire clamp so that the side of the locator away from the contact surface 11 faces the drill bit of the drilling machine. At this time, the operator can drill the wire clamp by using the lathe clamp 20 or by holding the handle of the wire clamp. Alternatively, the operator can mark the four reference positioning holes 12 of the locator on the wire clamp and then remove the locator, relying on the remaining points on the wire clamp to guide the punching of the wire clamp.

[0040] It should be understood that in the embodiments of this application, the four reference positioning holes 12 on the plate 10 are prefabricated, and their positional relationship is already determined and accurate. The operator can make the four reference positioning holes 12 align with the required opening position of the wire clamp by adjusting the position of the two clamps 20 relative to the plate 10. There is no need for the operator to measure repeatedly, which significantly reduces the steps and time for the operator to find the hole position. On the basis of improving accuracy, the efficiency of operation is significantly improved.

[0041] In summary, the embodiments of this application utilize a pre-defined positioning device. After the operator fixes the plate 10 onto the wire clamp, the pre-drilled reference positioning holes 12 on the plate 10 provide position guidance for the operator, enabling the operator to quickly and accurately complete the wire clamp drilling operation.

[0042] As a feasible specific implementation of this application, the virtual rectangle has two diagonals, each diagonal passing through the two vertices of the opposite corner of the virtual rectangle; the vertex is the endpoint of the diagonal, and the extension of the diagonal will pass through the vertex, and the position of the aforementioned vertex is also the center position of the reference positioning hole 12;

[0043] Each reference positioning hole 12 is surrounded by several first through holes 13. The first through holes 13 are opened through the plate 10. The central axis of the first through holes 13 is parallel to the central axis of the reference positioning hole 12. The several first through holes 13 around the reference positioning hole 12 are symmetrically distributed on both sides of the diagonal of the reference positioning hole 12.

[0044] In a specific application scenario, the positions and spacing of the four holes of the wire clamp vary depending on the specifications of the clamp. The position of the virtual rectangle formed by the four holes on the wire clamp also varies. By setting the configuration in this embodiment, the first through hole 13 is opened on both sides of the diagonal of each reference positioning hole 12, so that the positioner can meet the use of wire clamps of various sizes and specifications, thus improving its practicality.

[0045] Based on this, when viewed directly from the mating surface 11, the line connecting the centers of several first through holes 13 around the reference positioning hole 12 is perpendicular to the diagonal of the reference positioning hole 12. This ensures that the positions of the four first through holes 13 remain accurate, enabling the positioner to meet the needs of various sizes of wire clamps and improving its practicality.

[0046] Based on the above ideas, in some possible implementations of the embodiments of this application, each reference positioning hole 12 is surrounded by a number of second through holes 14. The second through holes 14 are opened through the plate 10. The central axis of the second through holes 14 is parallel to the central axis of the reference positioning hole 12. When viewed from the mating surface 11, the centers of the several second through holes 14 around the reference positioning hole 12 are linearly arranged on the diagonal of the reference positioning hole 12. Furthermore, the centers of some of the second through holes 14 around the reference positioning hole 12 are linearly arranged on the extension line of the diagonal of the reference positioning hole 12.

[0047] In this way, during use, the operator can select four of the second through holes 14 as guide holes to guide the positioning, so that the positioner can meet the use of wire clamps of various sizes and specifications, thus improving its practicality.

[0048] As a feasible specific implementation of the present application, two sets of sliding grooves 15 are provided on the plate 10. The two sets of sliding grooves 15 are symmetrically distributed on both sides of the virtual rectangle. Each set of sliding grooves 15 includes at least one sliding groove 15. The sliding groove 15 is a strip-shaped through groove provided on the plate 10 and passing through both sides of the plate 10. The central axis of the sliding groove 15 is perpendicular to the edge line of the sliding groove 15 near the virtual rectangle.

[0049] A threaded hole 21 is provided on one side of the clamp 20. The locking mechanism 30 includes a locking bolt 31. The stud of the locking bolt 31 can form a threaded connection with the threaded hole 21. When the stud of the locking bolt 31 forms a threaded connection with the threaded hole 21, the head of the locking bolt 31 can form a friction pair with the side of the plate 10 away from the contact surface 11, thereby fixing the position of the clamp 20 and the plate 10.

[0050] Let's take a specific use case as an example, where each set of slides has 15 slides;

[0051] In use, the operator passes the stud of the locking bolt 31 through the groove 15 to form a threaded pair with the clamp 20, so that the head of the locking bolt 31 is located on the side of the plate 10 away from the mating surface 11. After the two clamps 20 hold the wire clamp in a suitable position, the operator can tighten the locking bolt 31, so that the head of the locking bolt 31 is in close contact with the plate to form a friction pair, thereby fixing the position of the wire clamp. This operation method is simple and easy to operate, and takes less time.

[0052] Of course, each set of slide grooves 15 may also have two parallel slide grooves 15. There are two threaded holes 21 on the clamp 20 and two locking bolts 31 that are detachably connected to the same clamp 20. This makes the clamp 20 more stable after locking.

[0053] As a feasible specific implementation of this application, the plate 10 is also provided with a plurality of scale bars 16 on the contact surface 11. The scale bars 16 are located at the opening of the slide groove 15. By setting the scale bars 16, the operator can accurately control the position of the two clamps 20, thereby achieving the accuracy of the fixed position between the locator and the wire clamp.

[0054] Based on this, a micrometer 50 is installed on the side of the plate 10 away from the mating surface 11. The telescopic end of the micrometer 50, that is, the end of the micrometer screw near the anvil, can contact the locking bolt 31. When micro-feeding is required, the clamp 20 can be brought close to the wire clamp by pushing the locking bolt 31 with the micrometer 50. During installation, a micrometer 50 can be set on each side of the plate 10 to push the clamp 20 to move in opposite directions. A buckle can be installed on the side of the plate 10 away from the mating surface 11 to fasten the frame of the micrometer 50 to fix the micrometer 50.

[0055] Based on this, a level 40 is installed on the side of the plate 10 away from the mating surface 11. The level 40 does not obstruct the holes and grooves 15 opened on the plate 10. In this way, when using it, the operator can use the level 40 to correct the horizontal angle of the locator, thereby improving the accuracy. The level 40 can be a bubble type or an electronic type.

[0056] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
