Description

Technical Field

[0001] This utility model relates to the field of drilling assistance technology, specifically to an electrode-assisted drilling tool. Background Technology

[0002] In the production and maintenance of electromagnetic flowmeters, electrode installation is one of the core aspects determining the measurement accuracy of the equipment. Precise drilling is required at specific locations on the flowmeter housing to ensure the electrode is vertically embedded and reliably contacts the internal fluid, thereby accurately capturing the induced electromotive force signal generated by the fluid cutting the magnetic field. Drilling accuracy directly affects the electrode's installation compatibility and sealing performance: if the hole is misaligned, lacks verticality, or has a diameter deviation, it will not only prevent the electrode from being properly embedded but may also damage the housing's sealing structure, causing fluid leakage. Furthermore, electrode misalignment can interfere with the magnetic field distribution, increasing flow measurement errors.

[0003] Currently, the drilling operation for electromagnetic flowmeter electrodes in the industry mostly adopts the traditional method of "manual marking + hand guidance": the operator first marks the drilling point on the housing with a marker, and then holds the electric drill directly to the marked point to drill. This method has significant technical defects: First, it lacks a dedicated guiding mechanism. After the electric drill is started, it is easy to deviate due to hand shaking, uneven force application, or the radial force of the drill bit, resulting in the drill hole deviating from the preset position at an angle, and the verticality is difficult to control. Second, the existing operation does not have a suitable grip structure, and the friction between the palm and the drilling tool / housing is insufficient, making it easy to slip when applying force, which further aggravates the drilling deviation. Third, the flowmeter housing is mostly made of metal, and there is no insulation protection when operating by hand, which poses a risk of electric shock.

[0004] The aforementioned problems result in a low pass rate for traditional drilling methods, with frequent occurrences of issues such as "misaligned drilling requiring rework," "electrode installation jamming," and "seal failure requiring rework." This not only increases production and maintenance costs but also seriously affects the assembly efficiency and long-term operational stability of electromagnetic flowmeters. Therefore, there is an urgent need for an electrode-assisted drilling tool that can achieve precise guidance, convenient grip, and insulation protection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrode-assisted drilling tool, which solves the problem of high rework rates due to skewed drilling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrode-assisted drilling tool, comprising an auxiliary plate, wherein an insulating covering block is fixedly sleeved on the outer surface of the auxiliary plate, and an auxiliary drilling assembly is provided on the outer surface of the auxiliary plate, the auxiliary drilling assembly comprising two electrode auxiliary components, both of which are fixedly connected to the outer surface of the auxiliary plate. An auxiliary structure is provided on the upper surface of the insulating block. The auxiliary structure includes a connecting groove, which is formed on the outer surface of the insulating block.

[0007] Preferably, both of the electrode auxiliary components have auxiliary holes inside, and the connecting grooves are arranged linearly and equidistantly on the surface of the insulating cover block.

[0008] Preferably, the outer surface of the insulating cover block has two baffles integrally formed, and the two baffles are located on the front and rear sides of the insulating cover block.

[0009] Preferably, the two baffles are higher than the insulating cover block, and the outer surface of the insulating cover block is provided with a groove. At the same time, the position of the groove extends obliquely to the baffles to facilitate thumb placement. The groove is integrally formed with a connection point on the inner wall of the insulating cover block.

[0010] Preferably, the connection points are arranged at equal intervals, the insulating covering block, the baffle and the connection points are all made of insulating rubber, and there are two auxiliary structures.

[0011] Preferably, the auxiliary holes inside the two electrode auxiliary components have different diameters, which can be used to assist drilling of holes of different diameters.

[0012] Preferably, there are two auxiliary structures, located at both ends of the insulating covering block.

[0013] Compared with the prior art, the present invention provides an electrode-assisted drilling tool, which has the following advantages: 1. This electrode-assisted drilling tool, due to the certain length of the electrode auxiliary component, allows the drill bit to be inserted into the auxiliary hole at the start of drilling. This helps align the drill bit with the desired drilling position, ensuring that the drill bit drills vertically into the preset drilling position of the electromagnetic flowmeter. This avoids the possibility of the drilled hole deviating from the angle, and the drilled hole penetrates straight into the interior of the electromagnetic flowmeter. The use of this device improves drilling accuracy and increases practicality.

[0014] 2. This electrode-assisted drilling tool features a stop bar slightly higher than the insulating cover block, which also acts as a barrier for the thumb, facilitating the application of force. The connecting groove on the insulating cover block contacts the palm, increasing the contact area and friction, thus aiding in drilling the electrode mounting position of the electromagnetic flowmeter. In existing technologies, drilling is often done by simply marking the electrode position with a pen, which can easily result in misalignment. This tool improves accuracy and prevents the electrode from failing to fit during subsequent installation, increasing its practicality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a new technical solution: an electrode-assisted drilling tool, including an auxiliary plate 1, an insulating covering block 4 fixedly sleeved on the outer surface of the auxiliary plate 1, an auxiliary drilling assembly provided on the outer surface of the auxiliary plate 1, the auxiliary drilling assembly including two electrode auxiliary parts 2, both electrode auxiliary parts 2 are fixedly connected to the outer surface of the auxiliary plate 1, and auxiliary holes 3 are opened in the interior of both electrode auxiliary parts 2. An auxiliary structure is provided on the upper surface of the insulating covering block 4, the auxiliary structure including a connecting groove 8, the connecting groove 8 is opened on the outer surface of the insulating covering block 4, and the connecting groove 8 is arranged linearly and equidistantly on the surface of the insulating covering block 4; The outer surface of the insulating cover block 4 has two integrally formed baffles 5, which are located on the front and rear sides of the insulating cover block 4. The baffles 5 are higher than the insulating cover block 4. The outer surface of the insulating cover block 4 has a groove 6, which extends obliquely to the baffles 5 for easy thumb placement. The groove 6 is integrally formed with a connection point 7 on the inner wall of the insulating cover block 4. The connection points 7 are evenly spaced. The insulating cover block 4, the baffles 5 and the connection points 7 are all made of insulating rubber. There are two auxiliary structures.

[0019] Furthermore, the auxiliary holes 3 inside the two electrode auxiliary components 2 have different diameters, which can be used to assist in drilling holes of different diameters. There are two auxiliary structures, located at both ends of the insulating covering block 4.

[0020] Furthermore, when using this device to drill holes in the electromagnetic flowmeter, first firmly grasp the insulating cover block 4 with your left or right hand, then naturally place your thumb in the groove 6 and grip it tightly. Move the tool to the position in the electromagnetic flowmeter where the electrode plate needs to be drilled, and then place the device in the designated position. At this time, firmly grasp the drilling device with your left or right hand, then place the drill bit inside the auxiliary hole 3, align it, and start the drilling device to begin drilling. Because the electrode auxiliary part 2 has a certain length, when drilling begins, the drill bit is inserted into the auxiliary hole 3, which can help the drill bit to align with the position to be drilled. During drilling, the drill bit can be drilled vertically into the preset drilling position of the electromagnetic flowmeter, avoiding the possibility of the drilled hole deviating from the angle. The drilled hole is drilled straight into the interior of the electromagnetic flowmeter. The use of this device improves the drilling accuracy and increases practicality.

[0021] Furthermore, when using this device, two electrode auxiliary parts 2 of different diameters are simultaneously provided at the left and right ends of the auxiliary plate 1. The electrode auxiliary parts 2 have graduations nearby for easy size differentiation, and their orientation can be changed, facilitating the drilling of holes of different diameters, such as... Figure 2 The diameter is φ3.20±0.02, such as Figure 3 The diameter is φ4.20±0.02.

[0022] Furthermore, when using this device, when the thumb presses into the groove 6, the thumb contacts the connection point 7. Since the connection point 7 is relatively soft and evenly distributed, it can increase the friction and prevent the thumb from slipping when applying force. At the same time, the thumb also contacts the stop strip 5, which is slightly higher than the insulating cover block 4, and also has a blocking effect on the thumb, making it easier to apply force. The connecting groove 8 on the insulating cover block 4 contacts the palm, increasing the contact area and also increasing some friction, which facilitates auxiliary drilling of the electrode mounting position of the electromagnetic flowmeter. In the existing technology, the position of the electromagnetic flowmeter electrode is simply marked with a pen and then drilled directly, which is easy to drill crookedly. The use of this tool improves the accuracy and avoids the situation where the electrode cannot be installed later, thus increasing its practicality.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
