[0001] The invention relates to the technical field of drilling, and in particular to a multi-way reversing valve stem processing device. Background Art

[0002] In the structure of multi-way reversing valves, the valve stem plays a vital role. Its surface needs to be precisely processed with various fine channels including straight holes, threaded holes and complex eccentric holes to ensure the efficient operation of the fluid control system and its stability under various working conditions. However, the traditional process exposes several technical challenges when processing such slender channels with special geometric structures, especially the fixed stability and precise positioning of the valve stem during processing.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1 Reference Figure 1-3 , which is the first embodiment of the present invention, provides a multi-way reversing valve stem processing device, including a frame component 100, on which a clamp 304c component 200 and a drilling component 300 are installed, wherein the drilling component 300 includes a first electric lead screw 301 installed between the frame components 100, an adjusting seat 302 is installed on the first electric lead screw 301, a drilling rig 303 is installed on the adjusting seat 302, and a guide 304 is installed at the drill bit 303a of the drilling rig 303, and the guide 304 is used to limit and guide the drill bit 303a to prevent it from slipping or deviating.

[0029] In this embodiment, a guide 304 is added to the base of the drill bit 303a. The guide 304 is firmly and flexibly screwed to the drill bit 303a through a set of mounting sleeves 304a, allowing the guide 304 to achieve initial contact and fit with the valve stem without interfering with the normal operation of the drill bit 303a. A pair of automatically opened clamps 304c are configured at the front end of the guide 304. Using the principle of leverage, when the guide 304 contacts the outer wall of the valve stem and moves forward with the drill bit 303a, the clamps 304c automatically close and clamp the surface of the valve stem. This dynamic process not only provides initial positioning for the drill bit 303a, but also ensures that the drill bit 303a maintains stable contact with the valve stem through the clamping force to prevent any unnecessary sliding. A telescopic cylinder 304b is integrated inside the guide 304. When the drill bit 303a is pushed forward, the clamp 304c is closed to disengage the plug body 304b-6, so that the inside of the telescopic cylinder 304b is connected to the outside, thereby compressing the telescopic cylinder 304b. This design cleverly utilizes the propulsion force of the drill bit 303a, realizes the instant adjustment of the length of the guide 304, and ensures that the drill bit 303a continues to move forward.

[0030] Significantly improve processing accuracy: Through this improvement, the drill bit 303a is accurately guided and stably clamped by the guide 304 during the drilling process, which greatly reduces the risk of deviation of the drilling position, ensures that the opening position of the eccentric hole is accurate, and improves the overall accuracy of the multi-way reversing valve stem processing.

[0031] Enhanced operational safety: The intelligent clamping mechanism ensures the stability of the drill bit 303a while avoiding the problem of valve stem damage caused by over-clamping of the electric clamp 304c, maintaining the integrity of the workpiece and the reliability of subsequent use, and improving the safety factor of operation.

[0032] Improve work efficiency: Due to the automatic fitting and positioning function of the guide 304, the time and difficulty of manual alignment are reduced, making the drilling operation smoother and more efficient, thereby improving production efficiency.

[0033] Wide applicability: This design is not only suitable for the eccentric hole processing of the valve stem of the multi-way reversing valve, but its flexible adjustment mechanism and universal installation method also enable it to adapt to workpieces of different sizes and shapes, showing good versatility and adaptability.

[0034] Example 2 Reference Figure 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the frame component 100 includes an upper T-frame 101 and a lower T-frame 102, and a vertical frame 103 connecting the upper T-frame 101 and the lower T-frame 102.

[0035] The fixture 304c component 200 includes a sliding frame 201, which is slidably installed under the cross arm section of the upper T-frame 101. The cross arm section is provided with a third electric lead screw 202 for driving the sliding frame 201 to move. An electric double-headed lead screw is provided at the lower end of the sliding frame 201. A clamp 203 is provided at each end of the electric double-headed lead screw. The clamp 203 clamps the valve stem of the multi-way reversing valve to be processed.

[0036] The drilling component 300 also includes a first electric screw 301 installed on the upper T-frame 101 and the lower T-frame 102, the adjustment seat 302 is installed on the first electric screw 301, the adjustment seat 302 is installed with a second electric screw 305, the second electric screw 305 is installed with a moving seat 306, and the drilling rig 303 is installed on the moving seat 306.

[0037] The fixture 304c component 200 works by rotating the electric double-ended screw built into the slide frame 201. This operation can accurately adjust the distance between the clamps 203 located at both ends of the electric double-ended screw, ensuring that they can simultaneously apply a balanced and firm clamping force from both ends of the multi-way reversing valve stem to achieve a stable fixation of the valve stem. Once the valve stem is clamped, the third electric screw 202 is used to drive the slide frame 201 to move smoothly along the bottom surface of the upper T-shaped frame 101. This design enables the multi-way reversing valve stem to be safely and accurately transferred to the operating position of the drilling rig 303. This process not only ensures the positioning accuracy of the valve stem, but also prepares for the subsequent drilling process.

[0038] Adjustment of the drilling rig 303: In order to adapt to the drilling requirements at different positions, the drilling rig 303 is installed on the adjustment seat 302, and the adjustment seat 302 can be lifted up and down by the first electric screw 301 to ensure that the drill bit 303a is aligned with the predetermined height on the valve stem. In addition, the second electric screw 305 on the adjustment seat 302 is responsible for controlling the forward and backward movement of the moving seat 306, and further fine-tuning the forward and backward position of the drilling rig 303 to make the drilling operation more accurate and correct. Combined with the above mechanism, the drilling rig 303 can not only move up and down, forward and backward, but also cooperate with the left and right translation of the valve stem driven by the third electric screw 202. This series of compound movements ensures that the drilling rig 303 can perform comprehensive and accurate drilling operations on the valve stem of the multi-way reversing valve from all necessary angles, and can achieve efficient and high-quality processing for both straight holes and eccentric holes.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3 Reference Figure 2-5, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the guide member 304 includes a mounting sleeve 304a, the mounting sleeve 304a is mounted on the outside of the nut of the drill bit 303a, and two symmetrical telescopic cylinders 304b are rotatably arranged on the outside of the mounting sleeve 304a, and a clamp 304c is arranged at the front end of each telescopic cylinder 304b. A connecting rod 304d is fixedly connected to the side of the telescopic cylinder 304b, and one end of the connecting rod 304d is mounted in the mounting sleeve 304a through a bearing, and an electromagnet 304e is arranged at one end of the connecting rod 304d, and the electromagnet 304e is used to lock its rotation angle.

[0041] It should be noted that the guide 304 is screwed to the nut position of the drill bit 303a through the mounting sleeve 304a, and serves as a mounting platform for other components to ensure that the entire guide 304 and the drill bit 303a operate in coordination as a whole. Two symmetrical telescopic cylinders 304b are arranged on the outside of the mounting sleeve 304a, and a clamp 304c is assembled at the front end of each telescopic cylinder 304b. These clamps 304c first contact and fix the workpiece when the drill bit 303a approaches the workpiece, ensuring the correct alignment and initial stability of the drill bit 303a.

[0042] A connecting rod 304d is fixedly connected to the side of each telescopic cylinder 304b, and one end of the connecting rod 304d is installed inside the mounting sleeve 304a through a bearing. This design allows the connecting rod 304d to rotate freely within a certain range to achieve angle adjustment. An electromagnet 304e is installed at the other end of the connecting rod 304d. The function of the electromagnet 304e is to lock and unlock the rotation angle of the connecting rod 304d. Through the current control of the electromagnet 304e (timely power off and restart), the angle of the guide 304 can be flexibly adjusted to meet different processing requirements.

[0043] The advantages of the specific control mechanism of the electromagnet 304e are as follows: (1) Angle adaptive adjustment: By timely powering off the electromagnet 304e and releasing the lock on the connecting rod 304d, the operator can manually or automatically adjust the angle of the guide 304 according to the specific position of the workpiece and the drilling requirements, thereby achieving precise control of the offset angle. This design ensures that the optimal drilling entrance can be found even if there is a certain degree of unevenness or complex shape on the workpiece surface. (2) Guide stability and limit guarantee: Once the angle is adjusted appropriately, the electromagnet 304e restarts and locks the angle of the connecting rod 304d, ensuring that the offset angle of the guide 304 remains unchanged during the entire movement of the drill bit 303a. This feature is crucial to maintaining the stability and precise limit of the drill bit 303a guide, especially when processing deep holes or eccentric holes, which can significantly reduce the risk of drilling deviation or slippage and improve processing accuracy and finished product quality.

[0044] The telescopic cylinder 304b includes an outer cylinder 304b-1, an inner rod 304b-2 is provided inside the outer cylinder 304b-1 for limited sliding, a first spring 304b-3 for pushing the inner rod 304b-2 outward is provided inside the outer cylinder 304b-1, a channel 304b-5 is provided inside the inner rod 304b-2, a plug body 304b-6 that can be opened outward is provided at one end of the channel 304b-5 located at the notch 304b-4, a second spring 304b-7 for pushing the plug body 304b-6 outward is provided inside the channel 304b-5, and the plug body 304b-6 is blocked from moving outward by the clamp 304c in the expanded state.

[0045] It should be noted that the telescopic cylinder 304b includes an outer cylinder 304b-1 and an inner rod 304b-2 built into the outer cylinder 304b-1. The inner rod 304b-2 can slide in the keyway of the outer cylinder 304b-1. This design provides an adjustable length for the system to adapt to different processing requirements. The first spring 304b-3 is used to provide an outward thrust for the inner rod 304b-2. When there is no other external force, the first spring 304b-3 will try to push the inner rod 304b-2 to the outermost position, ensuring that the telescopic cylinder 304b maintains its maximum length in the initial state. A channel 304b-5 is opened inside the inner rod 304b-2. A plug body 304b-6 that can be opened outward is provided at one end of the channel 304b-5. The plug body 304b-6 exists to close the channel 304b-5 when necessary to control the internal air pressure or liquid flow. The movement of the plug 304b-6 is controlled by a second spring 304b-7 disposed in the channel 304b-5, which pushes the plug 304b-6 toward a closed state. When the clamp 304c (composed of two intersecting arc-shaped pieces 304c-1) is in an expanded state, its long end is located outside the plug 304b-6, which actually prevents the plug 304b-6 from moving outward. This means that only when the clamp 304c is deformed by an external force and no longer blocks the plug 304b-6, can the second spring 304b-7 push the plug 304b-6 to move.

[0046] Sequential control when the drill bit 303a advances: During the advancement of the drill bit 303a, the short section at the front end of the clamp 304c first contacts the workpiece and is compressed. The clamp 304c is deformed by the lever principle, and the long end is expanded. This process achieves a stable clamping of the workpiece. Then, as the clamp 304c deforms, it no longer hinders the plug body 304b-6, so the second spring 304b-7 pushes the plug body 304b-6 to move, opening the channel 304b-5 of the inner rod 304b-2. At this time, the first spring 304b-3 begins to compress, and the inner rod 304b-2 retracts, allowing the drill bit 303a to contact the workpiece. This design sequence ensures that the workpiece has been firmly fixed by the clamp 304c before the drill bit 303a contacts the workpiece, greatly reducing the risk of slipping during drilling.

[0047] Sequential recovery during withdrawal: When the drill bit 303a withdraws, the first spring 304b-3 first pushes the inner rod 304b-2 outward to return to its original position, and the telescopic cylinder 304b first returns to its initial length. This action occurs before the clamp 304c is restored. Subsequently, as the inner rod 304b-2 is fully extended, the plug body 304b-6 recloses the channel 304b-5 under the action of the second spring 304b-7, and the clamp 304c gradually returns to its initial open state under the action of the torsion spring 304c-3, and finally detaches from the workpiece. This design ensures that during the withdrawal process, the stable recovery of the telescopic cylinder 304b will not be disturbed by the recovery process of the clamp 304c, thereby improving the stability and safety of the overall system.

[0048] This carefully designed sequence and mechanism achieves orderly deformation and recovery of the drill bit 303a when it advances and retreats by accurately controlling the action sequence of the telescopic cylinder 304b and the clamp 304c, effectively ensuring the precise control of the machining process and the machining quality of the workpiece.

[0049] The front end of the inner rod 304b-2 is provided with a notch 304b-4, and the clamp 304c includes two cross-shaped arc pieces 304c-1, and the rotation shafts 304c-2 of the two arc pieces 304c-1 are located in the notch 304b-4, and the outer wall of the rotation shaft 304c-2 is sleeved with a torsion spring 304c-3 for resetting the two arc pieces 304c-1. The rotation shafts 304c-2 of the two arc pieces 304c-1 are set at a position deviating from the midpoint, dividing the arc piece 304c-1 into two parts, one long and one short, and the short part is located on the inner side. The position of the rotating shaft 304c-2 is offset from the midpoint. This design divides the two arc-shaped pieces 304c-1 into two parts of different lengths. The short section is located on the inner side, close to the workpiece. This asymmetric arrangement helps in the clamping process. Through the first contact and subsequent squeezing action of the short section, the long section flips to clamp the multi-way reversing valve stem, efficiently transmits power and achieves stable clamping of the workpiece. At the same time, the long section is located on the outer side to expand the distance between the upper and lower ends, so that it can better adapt to the multi-way reversing valve stems in different positions or multi-way reversing valve stems of different specifications.

[0050] In this embodiment, the front end of the guide 304 is equipped with a pair of clamps 304c composed of cross-shaped and staggered symmetrically arranged arc-shaped pieces 304c-1. These arc-shaped pieces 304c-1 rotate around the rotation axis 304c-2. In the initial stage, the short end of the arc-shaped piece 304c-1 first contacts the valve stem of the multi-way reversing valve. As the drill bit 303a is pushed forward, the short end is compressed, and the long end is driven to rotate around the rotation axis 304c-2 through the lever principle to close and clamp the valve stem of the multi-way reversing valve. In this process, the built-in torsion spring 304c-3 is compressed. The clamping force increases as the drill bit 303a approaches, thereby enhancing the clamping force on the valve stem of the multi-way reversing valve and ensuring the stable clamping of the valve stem of the multi-way reversing valve.

[0051] When the clamp 304c contacts the valve stem and begins to clamp it, the electromagnet 304e is powered off and restarted at the right time to unlock and re-lock the connecting rod 304d, so that the offset angle of the guide 304 is first ensured by the clamp 304c, and the adaptive adjustment of the angle is achieved. The offset angle is kept unchanged during the movement of the drill bit 303a, making its guidance stable, providing a solid guarantee for the precise guidance and limitation of the drill bit 303a.

[0052] Dynamic response of the telescopic cylinder 304b: when the long end of the arc-shaped piece 304c-1 of the clamp 304c rotates away from the outside of the plug body 304b-6, the built-in second spring 304b-7 prompts the plug body 304b-6 to move outward, thereby opening up the passage between the inner rod 304b-2 and the outer cylinder 304b-1, allowing the outer cylinder 304b-1 and the inner rod 304b-2 to expand and contract with the movement of the drill bit 303a, and at the same time, the first spring 304b-3 adaptively expands and contracts to create conditions for the contact of the drill bit 303a. This ingenious design ensures that the drill bit 303a can smoothly contact the valve stem surface and perform precise eccentric hole processing. At the same time, it also ensures that the reset sequence of the telescopic cylinder 304b is better than the reset sequence of the clamp 304c, thereby ensuring the processing sequence of the drill bit 303a.

[0053] Withdrawal and reset process: After the operation is completed, when the drill bit 303a retreats, the first spring 304b-3 in the telescopic cylinder 304b begins to recover, first causing the inner rod 304b-2 to extend, and then the entire telescopic cylinder 304b gradually returns to its initial length. After that, the clamp 304c gradually loosens its grip on the valve stem under the drive of the torsion spring 304c-3, and finally returns to its initial open state after the drill bit 303a is completely withdrawn, so as to be easily removed.

[0054] The remaining structure is the same as that of Example 2.
