Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a high-efficiency drilling equipment for valve production. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Valves have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their types and specifications are quite numerous.

[0003] Even-numbered holes (typically 4 or 8 holes) need to be machined at both ends of the valve to fix the flange. Existing valve drilling equipment usually adopts a single-axis, unidirectional drilling process when machining the end connection holes to adapt to valves of different diameters. This requires the drilling equipment to process each hole through multiple station switching. After completing the machining of a single hole, the hole position needs to be switched by rotating or translating the worktable. It takes multiple repetitive operations to complete all the drilling, resulting in drilling efficiency that needs to be improved. Therefore, a high-efficiency drilling equipment for valve production is proposed. Utility Model Content

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0030] Example 1

[0031] Reference Figures 1-3 The first embodiment of this utility model provides a high-efficiency drilling equipment for valve production, which can drill the end of the valve on multiple axes to reduce drilling time and improve the efficiency of drilling operations. It includes: a clamping and fixing unit 100, a lifting and deflection unit 200 and a drilling unit 300.

[0032] The clamping and fixing unit 100 includes a support platform 101, and a clamping part 102 for clamping the valve is provided on the top of the support platform 101.

[0033] A lifting and deflection unit 200 is provided on the support platform 101. The lifting and deflection unit 200 includes a lifting part 201 and a deflection part 202. The lifting part 201 is used to lift and lower the deflection part 202, and the deflection part 202 is used to adjust the drilling angle.

[0034] A drilling unit 300 is provided on the deflection part 202. The drilling unit 300 includes a quantitative adjustment part 301 and a drilling part 302 provided on the quantitative adjustment part 301. The quantitative adjustment part 301 is used to adjust the drilling span of the drilling part 302 according to the valve size. The drilling part 302 is used to drill the valve with multiple axes.

[0035] The support platform 101 serves as the basic load-bearing structure. After the valve is placed in the center of the platform, the clamping part 102 clamps and fixes the valve to ensure that the valve remains stationary during the drilling process. The lifting part 201 can drive the deflection part 202 to rise and fall vertically to position the drilling height. The deflection part 202 can rotate the drilling unit 300 at a preset angle (such as 90° or 45°) to achieve angular positioning of the annular equidistant holes (such as 4 holes or 8 holes) at the valve end.

[0036] The quantitative adjustment unit 301 can adjust the drilling span of the drilling unit 302 according to the valve size, so that the drilling unit 302 can adapt to valves of different specifications. The entire device is controlled by an external controller to ensure precise matching between various components. During drilling, the CNC system controls the lifting unit 201 to drive the drilling unit 300 to descend to the processing position. The drilling unit 302 then performs single-hole processing on the valve. After processing is completed, the lifting unit 201 drives the drilling unit 302 to rise and detach from the workpiece. The deflection unit 202 rotates at a preset angle and descends again to process the next set of holes. This can reduce the positioning time by more than 50% and improve drilling efficiency.

[0037] Example 2

[0038] Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, the clamping part 102 includes a plurality of electric push rods 102a fixedly installed on the top of the support platform 101. The plurality of electric push rods 102a are distributed in a ring at equal intervals, and the output end of each electric push rod 102a is fixedly connected to a clamping plate 102b.

[0039] The clamping part 102 achieves adaptive clamping of the valve through the ring-shaped electric push rod 102a assembly. When the valve is placed in the center of the support platform, the output end of each electric push rod 102a extends out and pushes the clamping plate 102b to move radially, forming a multi-directional uniform clamping force. This can adapt to valves with different outer diameters and ensure that the valve is stable and does not shake during drilling.

[0040] The support platform 101 has a circular groove 103 on its top, and each clamping plate 102b has multiple trapezoidal protrusions on one side for clamping.

[0041] The circular groove 103 on the top of the support platform 101 positions the bottom of the valve, restricts its axial movement, and assists the operator in positioning the valve at the center of the support platform 101 according to the center position of the circular groove 103, so as to clamp the valve. The protrusion of the clamping plate 102b adopts a trapezoidal cross-section design. The protrusion increases the contact area between the clamping plate 102b and the valve, thereby providing greater friction and ensuring that the clamping plate 102b can firmly fix the valve and prevent it from sliding or loosening during drilling.

[0042] Example 3

[0043] Reference Figure 1 and Figure 2 This is the third embodiment of the present utility model. Unlike the previous embodiment, the lifting part 201 includes a portal frame 201a fixedly connected to the top of the support platform 101. An electric telescopic rod 201b is fixedly installed on the top of the portal frame 201a, and the output shaft of the electric telescopic rod 201b slides through the portal frame 201a.

[0044] The gantry frame 201a fixed to the top of the support platform 101 provides rigid support for the lifting mechanism. The output shaft of the electric telescopic rod 201b installed at the top controls the extension and retraction of the telescopic rod through an electrical signal, and precisely adjusts the vertical height of the deflection part 202 below.

[0045] In addition, the deflection part 202 includes a rectangular frame 202a fixedly connected to the bottom of the output end of the electric telescopic rod 201b. A drive motor 202b is fixedly installed at the bottom of the inner cavity of the rectangular frame 202a, and the output shaft of the drive motor 202b rotates through the rectangular frame 202a.

[0046] The rectangular frame 202a is raised and lowered by an electric telescopic rod 201b. The drive motor 202b inside the rectangular frame 202a drives the drilling unit 300 installed at its lower end to rotate. The drive motor 202b adopts a servo control system and can rotate precisely at preset angles (such as 45° and 90°). With the annular hole layout at the valve end (such as 4 holes evenly distributed corresponding to 90° division), the circumferential positioning of the drilling position is realized, eliminating the need for multiple station switching of traditional equipment and greatly improving processing efficiency.

[0047] Example 4

[0048] Reference Figure 2 and Figure 3 This is the fourth embodiment of the present invention. Unlike the previous embodiment, the quantitative adjustment part 301 includes a support plate 301a fixedly connected to the bottom of the output end of the drive motor 202b. The top of the support plate 301a has two symmetrically opened sliding grooves 301b, and multiple mounting holes 301c are opened on both sides of the sliding grooves 301b. I-beams 301d are slidably arranged in both sliding grooves 301b. The I-beams 301d are fixed to the support plate 301a by bolts and nuts cooperating with the mounting holes 301c. The mounting holes 301c are used to adjust the span of the drilling part 302.

[0049] Two symmetrically arranged grooves 301b on the top of the support plate 301a provide sliding guides for the I-beam plate 301d. When it is necessary to adjust the drilling span, the bolts and nuts are loosened, and the I-beam plate 301d can slide laterally along the grooves 301b. The distance between the two I-beam plates 301d is adjusted according to the circumferential diameter of the hole at the valve end. After adjustment, the I-beam plate 301d is fixed by the cooperation of the bolts and nuts with the mounting hole 301c, forming a rigid connection structure to ensure that the span is stable and without deviation during drilling. This allows it to be adapted to valves of different diameters.

[0050] Among them, the support plate 301a has two sets of scale lines 301e corresponding to the mounting holes 301c on one side, and each I-beam plate 301d has a triangular groove 301f corresponding to the scale line 301e on one side. The scale line 301e and the triangular groove 301f constitute a visual positioning structure.

[0051] The scale line 301e on one side of the support plate 301a is precisely marked according to the spacing of the mounting holes 301c. The triangular groove 301f on the side of each I-beam 301d serves as an alignment mark. During adjustment, the operator can quickly determine the sliding position of the I-beam 301d by visually aligning the triangular groove 301f with the scale line 301e, so as to ensure that the sliding distance of the two I-beams 301d is the same and that it is compatible with the size of the valve.

[0052] In addition, the drilling section 302 includes two servo motors 302a, which are respectively fixed on the top of two I-beams 301d. The output end of each servo motor 302a rotates through the corresponding I-beam 301d and is fixedly connected to a drill bit 302b.

[0053] When the drive motor 202b drives the quantitative adjustment unit 301 to rotate to the target hole position angle, the servo motor 302a drives the drill bit 302b to rotate at high speed. Combined with the vertical feed of the lifting unit 201, the valve end dual holes are processed synchronously. Compared with traditional single-axis drilling, it can save half the time and make the drilling operation more efficient.

[0054] During use, the valve is placed in the circular groove 103 on the top of the support platform 101. Then, according to the circumferential diameter of the hole at the valve end, the fixing bolts and nuts of the I-beam plate 301d are removed, allowing it to slide laterally along the slide groove 301b. After aligning the triangular groove 301f with the scale line 301e to fit the valve size, the I-beam plate 301d is fixed again with bolts and nuts and mounting holes 301c, thereby determining the span of the drilling part 302. Then, the clamping part 102 is activated, and the electric push rod 102a extends to push the clamping plate 102b to firmly clamp the valve. Subsequently, the electric telescopic rod 201b drives the rectangular frame 202a to descend, bringing the drilling unit 300 closer to the valve. The lifting part 201 drives the drilling unit 300 to feed vertically, and the servo motor 302a drives the drill bit 302b to rotate at high speed. With the vertical feed of the lifting part 201, the simultaneous processing of the two holes at the valve end is achieved.

[0055] After a single drilling operation is completed, the electric telescopic rod 201b drives the drilling unit 300 to rise and detach from the workpiece. The drive motor 202b of the deflection part 202 rotates the support plate 301a at a preset angle (such as 45° or 90°) to adjust the drilling position. After the adjustment is completed, the electric telescopic rod 201b descends again, and the servo motor 302a drives the drill bit 302b to perform the next set of double hole processing. This process is repeated until all holes are drilled. The drilling operation is completed. The electric telescopic rod 201b drives the rectangular frame 202a to rise and reset. The electric push rod 102a retracts and pulls the clamping plate 102b to release the valve. The operator can then remove the valve that has been drilled.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
