Description

Technical Field

[0001] This utility model relates to the field of tooling, and more particularly to drilling tooling, especially a general-purpose tooling for drilling operating shafts. Background Technology

[0002] The operating shaft on the switchgear serves to support and rotate. It is characterized by its simple structure, convenient installation, and long service life. When machining the operating shaft, it is necessary to machine the corresponding mounting holes on the operating shaft according to different switchgear models. Traditionally, drilling holes on the operating shaft is limited by tooling fixtures, and each time only holes at a specific distance can be drilled, resulting in poor versatility. Drilling holes at different positions requires specific clamping fixtures, which is very troublesome, inefficient, and costly, making it unsuitable for widespread use.

[0003] Chinese invention patent publication number CN102034623A discloses an operating shaft for a grounding switch interlocking mechanism in a high-voltage switchgear. The operating shaft includes a shaft body and is composed of three parts. The part adjacent to a bare busbar and the grounding switch is an epoxy resin glass cloth rod. On each side of this epoxy resin glass cloth rod is an operating shaft made of metal material. The two ends of the epoxy resin glass cloth rod are respectively placed in holes at the inner ends of two sleeves. The holes at the outer ends of these two sleeves are respectively matched with the inner ends of their respective metal operating shafts. Two pins are respectively inserted into radial holes at the inner ends of the two sleeves and radial holes at the ends of the epoxy resin glass cloth rod. Two other pins are respectively inserted into radial holes at the outer ends of the two sleeves and radial holes at the ends of the two metal operating rods. Utility Model Content

[0004] This utility model aims to overcome the shortcomings of the prior art by providing a universal tooling for drilling operating shafts, which is highly versatile and accurate, thus meeting the needs of high versatility, high precision, and low cost in drilling operating shafts.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This universal tooling for drilling operating shafts includes a first base block, a first mounting groove with a "V" shaped cross section on the first base block, a pair of opposing first slots on the first base block, a first locking block inserted into the two first slots on the first base block, a first clamping bolt threaded onto the first locking block, a first insertion hole on the first base block, a graduated round bar inserted into the first insertion hole, a first scale on the side of the first base block, a guide drilling block inserted into the two first slots at the opposite position of the first locking block, a guide hole aligned with the center of the first mounting groove on the guide drilling block, a first tightening bolt threaded onto the guide drilling block, an indicator needle cooperating with the first scale fixed on the side of the guide drilling block, and a first edge alignment block installed on the first base block at the side end of the first mounting groove. The functions of the first placement slot, the first slot, the first locking block, and the first clamping bolt are to enable rapid positioning, limiting, and clamping of the workpiece placed in the first placement slot. The "V" shape of the first placement slot is to automatically align the center of the operating axis and to quickly position and limit the operating axis, preventing it from moving around. The functions of the guide drilling block, guide hole, first clamping bolt, indicator needle, first scale, and scale bar are to enable precise drilling of holes of different sizes and positions.

[0006] Further improvements include a second base block positioned relative to the first base block, with a second insertion hole on the second base block into which the graduated rod is inserted. The second base block also has a pair of opposing second slots and a second placement groove with a "V"-shaped cross-section. A second locking block is provided on the second base block, which is inserted into the two second slots. A second clamping bolt is threaded onto the second locking block. A second edge alignment block is installed on the side of the second slot. A guide rod is fixed to the first base block, and a third insertion hole is provided on the second base block, where the guide rod is inserted and engaged. A second tightening bolt is threaded onto the second base block to tighten against the graduated rod. The function of the second base block here is to process long operating shafts; the function of the second slot, the second mounting slot, the second locking block, the second clamping bolt, and the second edge alignment block is to clamp and fix the outer end of the long operating shaft; the function of the second mounting slot being "V" shaped is to automatically align the center of the operating shaft, and also to quickly position and limit the operating shaft, preventing the operating shaft from moving around.

[0007] Further improvements include the application of a self-lubricating layer to the surfaces of the two first slots, the first insertion hole, the second insertion hole, the second slot, and the third insertion hole. The purpose of this self-lubricating layer is to facilitate easy movement of the first locking block, the guide drilling block, and the second locking block with low frictional resistance, preventing jamming. It also facilitates easy movement of the first base block and the second base block with low frictional resistance, preventing jamming due to inability to push them forward. This self-lubricating layer is made of tin bronze.

[0008] Further improvements include a pair of threaded holes on the side ends of both the first and second base blocks. The first edge alignment block and the first base block, as well as the second edge alignment block and the second base block, are secured together using butterfly bolts that engage with the threaded holes. The threaded holes and butterfly bolts allow for quick assembly and disassembly of the first and second edge alignment blocks, accommodating different lengths of operating shafts. When the operating shaft is short, only the first base block is needed to machine the holes; therefore, the first edge alignment block is installed on the first base block for aligning the ends of the operating shaft, facilitating the precise drilling of holes with varying spacings. When the operating shaft is long, the second edge alignment block on the second base block is used to align the outer and inner ends of the operating shaft. After this alignment, the first edge alignment block on the first base block needs to be removed, allowing for convenient and quick drilling of holes with different spacings on longer operating shafts.

[0009] To further improve the design, a second scale is provided on the side of the second base block. The purpose of this second scale is to allow the operator to determine the length of long operating axes, thereby providing data support for subsequent machining of holes with different spacings.

[0010] The beneficial effects of this utility model are:

[0011] 1) The first placement slot, the first slot, the first locking block, and the first clamping bolt enable rapid positioning, limiting, and clamping of the workpiece placed in the first placement slot;

[0012] 2) Through the guide drilling block, guide hole, first tightening bolt, indicator needle, first scale, and scale bar, holes of different positions and sizes can be drilled;

[0013] 3) The second base block, the second mounting slot, the second clamping block, the second clamping bolt, and the second edge alignment block can clamp long operating shaft workpieces and prepare for subsequent precise multi-position drilling. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Referring to the attached diagram: This universal tooling for drilling operating shafts includes a first base block 1, on which a first mounting groove 1-1 with a "V"-shaped cross-section is formed; a pair of opposing first slots 1-2 are provided on the first base block 1; a first locking block 2 is provided on the first base block 1, which is inserted into the two first slots 1-2; a first clamping bolt 3 is threaded onto the first locking block 2; a first insertion hole 1a is formed on the first base block 1; a graduated round bar 6 is inserted into the first insertion hole 1a; the first... The base block 1 has a first scale 1b on its side. The first locking block 2 has a guide drilling block 7 that is inserted into the two first locking slots 1-2. The guide drilling block 7 has a guide hole 7-1 that is aligned with the center of the first mounting slot 1-1. The guide drilling block 7 is threaded with a first tightening bolt 8. The guide drilling block 7 has an indicator needle 9 that mates with the first scale 1b fixed on its side. The first mounting slot 1-1 has a first edge alignment block 10 installed on the first base block 1.

[0027] A second base block 11 is positioned relative to the first base block 1. The second base block 11 has a second insertion hole 11a, into which the scale rod 6 is inserted. The second base block 11 has a pair of opposing second slots 11-1 and a second placement slot 11-2 with a "V" shaped cross section. The second base block 11 has a second locking block 12 that is inserted into the two second slots 11-1. A second clamping bolt 13 is threaded onto the second locking block 12. A second edge alignment block 15 is installed on the side of the second slot 11-1. A guide rod 5 is fixed on the first base block 1. A third insertion hole 11b is opened on the second base block 11, into which the guide rod 5 is inserted. A second tightening bolt 16 is threaded onto the second base block 11 to tighten against the scale rod 6.

[0028] The surfaces of the two first slots 1-2, the first insertion hole 1a, the second insertion hole 11a, the second slot 11-1, and the third insertion hole 11b are all provided with a self-lubricating layer 17.

[0029] A pair of threaded holes 4 are provided on the side ends of the first base block 1 and the second base block 11. The first edge alignment block 10 and the first base block 1, as well as the second edge alignment block 15 and the second base block 11, are fastened together by butterfly bolts 18 and threaded engagement with the threaded holes 4.

[0030] A second scale 11c is provided on the side of the second base block 11.

[0031] The working principle of this utility model is as follows: When clamping the short operating shaft workpiece 19, only the first base block 1 is needed. First, the short operating shaft workpiece 19 is placed in the first placement slot 1-1 for automatic center alignment. Then, the operating shaft workpiece is moved so that its end is aligned with the first edge alignment block 10. The first clamping bolt 3 is tightened by a tool, causing the first clamping nut 3 to move down and quickly and accurately clamp the operating shaft workpiece 19. Subsequently, the guide drilling block 7 is moved, and the spacing is adjusted according to the indicator needle 9 and the first scale 1b. After adjusting the spacing, the first tightening bolt 8 is tightened to lock the position of the guide drilling block 7. Then, the drill is used to drill the short operating shaft workpiece 19 through the guide hole 7-1. If a larger spacing hole is to be drilled, the scale bar 6 can be adjusted. Without moving the first edge alignment block 10, when the first locking block 2 is released and the first base block 1 is moved, the required drilling position on the operating shaft workpiece 19 (the short operating shaft workpiece) can be accurately calculated based on the dimension of the first scale 1b on the first base block 1 plus the dimension on the scale bar 6. Figure 9 (As shown).

[0032] When clamping the long operating shaft workpiece 19, the first base block 1 is used to clamp the head end of the long operating shaft workpiece 19, and the second base block 11 is used to clamp the tail end of the long operating shaft workpiece 19. The head end and tail end of the long operating shaft workpiece 19 are aligned by the first edge alignment block 10 and the second edge alignment block 15, respectively. After alignment, the first edge alignment block 10 is removed by loosening the butterfly bolt 18, and the head end and tail end of the long operating shaft workpiece 19 are clamped by the first clamping bolt 3 and the second clamping bolt 13. Then, the guide drilling block 7 is moved and the spacing is adjusted according to the indicator needle 9 and the first scale 1b. After the spacing is adjusted, Tighten the first tightening bolt 8 to lock the position of the guide drilling block 7. Then, the drilling machine can drill through the guide hole 7-1 to the head end of the long operating shaft workpiece 19. Since the long operating shaft workpiece 19 is relatively long, the drilling of the rear end of the long operating shaft workpiece 19 requires locking the second tightening bolt 16. Then, the first base block 1 moves under the guidance of the guide round bar 5 (the guide round bar 5 moves by inserting into the second base block 11, and the scale round bar 6 moves by inserting into the first base block 1). The drilling spacing of the rear end of the long operating shaft workpiece 19 can be accurately calculated by adding the dimensional data of the first scale 1b to the large value on the scale round bar 6. Figure 10 As shown in the figure, it can adapt to drilling and clamping operations of long operating shaft workpieces, making it more versatile, more precise, and with lower processing costs, and is worth promoting and applying.
