[0002] The valve tapping process is typically completed using a tapping machine (refer to the valve tapping and drilling integrated machine disclosed in Chinese authorized patent CN217223658U). For small valves, to facilitate continuous processing, it is currently common practice for workers to hold the valve by hand and fix it with a quick clamp, and then drive the tapping drill bit down to open the hole.

[0003] To improve processing efficiency, it is necessary to optimize existing processes and reduce the additional step of using quick clamps. Utility Model Content

[0004] The purpose of this invention is to provide a valve drilling and tapping device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve drilling and tapping device, comprising a movable mold table that moves relative to a fixed mold table, wherein: The moving mold platform is fixedly welded with parallelly distributed abutting parts and guide parts, and the guide parts include a first vertical part with the smallest distance between the abutting parts; The fixed mold table includes a valve assembly cylinder that slides horizontally. One end of the valve assembly cylinder has an inclined surface that slides with the guide portion. When the vertical distance between the fixed mold table and the moving mold table is at its minimum, the valve assembly cylinder contacts the vertical portion, thereby moving axially so that the valve inserted at the other end abuts against the abutting portion and is fixed.

[0006] Preferably, an inner liner plate is fixedly installed on the side of the moving mold table facing the fixed mold table, and the abutting part and the guide part pass through the opening on the inner liner plate; A drive motor is fixedly installed in the groove on the side of the inner liner facing the moving mold table, and the wire-opening drill bit at the output end of the drive motor extends to the outside of the inner liner.

[0007] Preferably, when the inclined surface contacts the vertical part, the perforation on the valve assembly cylinder is coaxial with the thread-opening drill bit.

[0008] Preferably, a mounting base is fixedly installed on the fixed mold platform, and the mounting base has a mounting hole for assembling the valve assembly cylinder; An equidistant spring connected to the valve assembly cylinder is fixedly installed on the side of the mounting base adjacent to the guide portion. The equidistant spring is used to ensure that the inclined surface is always in contact with the side of the guide portion.

[0009] Preferably, guide rods are symmetrically fixedly installed on the fixed mold platform, and the guide rods are slidably installed on the guide columns fixedly installed on the moving mold platform.

[0010] Preferably, a top cover parallel to the moving mold table is fixedly installed on the fixed mold table, and a piston-type hydraulic telescopic rod with its output end fixedly installed on the top cover is fixedly installed on the moving mold table.

[0011] Preferably, a support is fixedly installed on the fixed mold platform, and rubber anti-rotation blocks with a sloping triangular cross-section are symmetrically arranged on the top of the support platform. The valve sidewall, which is inserted into the valve assembly cylinder, contacts the sloping surface of the rubber anti-rotation block. The inclined surface of the rubber anti-rotation block is a raised surface.

[0012] Preferably, the guide portion includes a recessed portion, the recessed portion including a second vertical portion and inclined portions disposed at both ends of the second vertical portion; One end of one of the inclined portions is fixedly connected to the first vertical portion.

[0013] Preferably, the contact part is a tough steel plate.

The fourth vertical portion is distributed close to the valve assembly cylinder, and an inclined guide portion that is slidably connected to the valve sidewall inserted into the valve assembly cylinder is fixedly installed at the end of the fourth vertical portion.

[0015] Preferably, a positioning rod is fixedly installed on the moving mold platform, passing through a through hole in the inner liner plate, and the positioning rod is in sliding engagement with a plug hole on the top of the mounting base.

[0016] In the above technical solution, the valve drilling and tapping device provided by this utility model has the following beneficial effects: First, the valve to be drilled is inserted into the port of the valve assembly cylinder. Then, as the moving mold table is driven down towards the fixed mold table, the inclined surface of the valve assembly cylinder moves along the guide part. After reaching the first vertical part, the valve assembly cylinder moves towards the contact part, causing the valve to contact the contact part, thereby fixing the valve to be drilled.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a valve drilling and tapping device includes a fixed mold table 1 and a movable mold table 2 that can move relative to the fixed mold table 1. Parallel abutment portions 21 and guide portions 22 are fixedly welded onto the movable mold table 2. The guide portion 22 has a first vertical portion 221, which is the portion of the guide portion 22 with the smallest distance between it and the abutment portion 21.

[0022] A valve assembly cylinder 11, which can slide horizontally, is provided on the fixed mold table 1. One end of the valve assembly cylinder 11 is provided with an inclined surface 111, which slides in cooperation with the aforementioned guide portion 22. When the vertical distance between the fixed mold table 1 and the moving mold table 2 reaches its minimum value, the inclined surface 111 of the valve assembly cylinder 11 will contact the first vertical portion 221 of the guide portion 22 and be guided by it to move axially, so that the valve workpiece inserted at the other end moves toward the contact portion 21 and is pressed tightly against the contact portion 21, thereby achieving a firm fixation of the valve.

[0023] In a preferred embodiment, an inner liner plate 23 is fixedly installed on the side of the moving mold table 2 facing the fixed mold table 1. Both the contact portion 21 and the guide portion 22 pass through corresponding openings in the inner liner plate 23. A groove is provided on the side of the inner liner plate 23 facing away from the fixed mold table 1, and a drive motor (not shown in the figure) is fixedly installed in the groove. A thread-cutting drill bit 4 is mounted at the output end of the drive motor, extending to the outside of the inner liner plate 23 to perform machining tasks.

[0024] Furthermore, when the inclined surface 111 of the valve assembly cylinder 11 contacts the first vertical part 221 of the guide part 22, the pre-drilled hole on the valve assembly cylinder 11 should be coaxial with the thread-cutting drill bit 4 to ensure machining accuracy.

[0025] A mounting base 12 is also fixedly installed on the fixed mold table 1. The mounting base 12 has mounting holes for assembling the valve assembly cylinder 11. An equidistant spring (not shown in the figure) is fixedly installed on the side of the mounting base 12 near the guide portion 22. The other end of the equidistant spring is connected to the valve assembly cylinder 11. The function of the equidistant spring is to provide a continuous elastic force, ensuring that the inclined surface 111 of the valve assembly cylinder 11 always remains in contact with the side of the guide portion 22, thus ensuring the reliability of the movement trajectory.

[0026] In order to accurately guide the movement of the moving mold table 2, guide rods 13 are symmetrically fixedly installed on the fixed mold table 1. These guide rods 13 are slidably sleeved in the guide columns 24 fixedly installed on the moving mold table 2.

[0027] The drive mechanism of the device is preferably hydraulic. A top cover 5 parallel to the moving mold table 2 is fixedly installed on the fixed mold table 1. A piston-type hydraulic telescopic rod 6 is fixedly installed on the top cover 5. The output end of the hydraulic telescopic rod 6 is fixedly connected to the moving mold table 2 and is used to drive the moving mold table 2 to perform reciprocating motion in the vertical direction.

[0028] To prevent the valve from rotating during processing, a support platform 7 is fixedly installed on the fixed mold table 1. A pair of rubber anti-rotation blocks 8 with a beveled triangular cross-section are symmetrically arranged on the top of the support platform 7. When the valve is inserted into the valve assembly sleeve 11, its sidewall will contact the beveled surface of the rubber anti-rotation block 8. The beveled surface of the rubber anti-rotation block 8 is preferably a raised curved surface to increase the contact area and improve the anti-rotation effect.

[0029] As an optimized shape of the guide portion 22, it may also include a recess 222. The recess 222 is composed of a second vertical portion and inclined portions located at both ends thereon. One end of one of the inclined portions is fixedly connected to the aforementioned first vertical portion 221, forming a smoothly transitioning guide trajectory.

[0030] Preferably, the contact part 21 is made of tough steel plate, so that it provides rigid support while having a certain impact resistance.

[0031] The contact portion 21 may include a third vertical portion 211 and a fourth vertical portion 212 arranged in parallel. The third vertical portion 211 and the fourth vertical portion 212 are fixedly connected by an inclined connecting portion 213. The fourth vertical portion 212 is located closer to the valve assembly cylinder 11, and an inclined guide portion 214 is fixedly installed at its end. When the valve is pushed against the contact portion 21, its sidewall will slide against the inclined guide portion 214, thereby smoothly guiding the valve to its final fixed position.

[0032] To ensure the alignment accuracy of the moving mold platform 2 and the fixed mold platform 1 during mold closing, a positioning rod 25 is also fixedly installed on the moving mold platform 2. The positioning rod 25 passes through the through hole opened on the inner liner plate 23 and can form a sliding fit with the insertion hole opened on the top of the mounting base 12.

[0033] The working principle is as follows: In the initial state, the moving mold platform 2 is separated from the fixed mold platform 1. The operator first inserts the valve workpiece to be drilled into the port of the valve assembly cylinder 11.

[0034] When the equipment is started, the piston-type hydraulic telescopic rod 6 drives the moving mold table 2 to move down and approach the fixed mold table 1. During this process, the inclined surface 111 at one end of the valve assembly cylinder 11 slides along the contour of the guide portion 22. When it slides to the first vertical portion 221, under the synergistic action of the equidistant springs, the valve assembly cylinder 11 is pushed and begins to move horizontally toward the contact portion 21, thereby pressing the valve workpiece inserted thereon tightly against the contact portion 21, completing the automatic clamping of the valve.

[0035] As the moving mold table 2 continues to move downward, the thread-cutting drill bit 4 is fed in to perform drilling or tapping on the valve that has been firmly fixed.

[0036] After processing, the piston-type hydraulic telescopic rod 6 drives the moving mold table 2 to move upward, returning to its initial state. During this reset process, the contour of the guide part 22 guides the valve assembly cylinder 11 to move horizontally backward, releasing the clamping force on the valve. The operator can then remove the processed valve from the valve assembly cylinder 11 and replace it with a new valve to be processed, thus enabling continuous and efficient batch processing.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
