Description

Technical Field

[0001] The utility model relates to the technical field of tungsten needle grinding, in particular to a universal tungsten needle grinding device. Background Art

[0002] As is well known, a tungsten needle is a slender tungsten product made of pure tungsten or tungsten alloy. It can be used as the electrode material in argon arc welding technology and also as an instrument probe, with advantages such as high temperature resistance and good electrical conductivity. When in use, according to requirements, the tungsten needle needs to be ground so that one end of the tungsten needle presents a required sharp angle, thus a grinding machine is needed.

[0003] Currently, existing ones are mainly light and portable in structure, mainly consisting of a handheld main body and a grinding head. Specifically, as disclosed in a tungsten needle sharpening machine with the patent number CN202220084772.8, it includes a motor main body and a grinding head connected by brackets at the bottom. The motor rotor of the motor main body is connected to a transmission shaft through a connector. The transmission shaft penetrates through the grinding head and is connected to a grinding disc in the grinding chamber of the grinding head. A window main body is penetrated inside the grinding head, and a tungsten needle holder communicating with the grinding chamber is penetrated through the window main body. The grinding head is provided with a transposition hole corresponding to the tungsten needle holder to enable its axial movement. Although the tungsten needle can be ground and the angle can be freely adjusted during grinding, the selection of the angle completely depends on the operator holding the tungsten needle holder by hand, inserting it into the transposition hole for rotation and holding, without angle locking. For tungsten needle grinding, the grinding angle completely depends on the operator's hand feeling to control, and there are easily errors in grinding. In addition, the whole only has the function of tungsten needle grinding, with a single function.

[0004] Therefore, it is necessary to upgrade the functions of the existing tungsten needle grinding device. Summary of the Utility Model

[0024] As Figures 1 to 5 shown, a universal tungsten needle grinding device provided in this embodiment includes a motor main body 1, a grinding body 2, and a holder insertion seat 3. A grinding chamber 21 is provided at the bottom end of the grinding body 2. One end of the motor main body 1 is detachably installed at the opening of the grinding chamber 21. Specifically, the opening of the grinding chamber 21 is threadedly connected to one end of the motor main body 1, and the grinding head 11 of the motor main body 1 is placed in the grinding chamber 21. A side plate 4 is provided on the grinding body 2. Two first strip-shaped through cavities 41 are provided on the side plate 4 in the vertical direction. A second strip-shaped through cavity 42 is established between the two first strip-shaped through cavities 41 in the vertical direction. A sliding rod 32 is provided on the end face of the holder insertion seat 3. The sliding rod 32 is inserted into the second strip-shaped through cavity 42. Bolts 43 are respectively inserted through the first strip-shaped through cavities 41. The width of the first strip-shaped through cavities 41 is greater than the diameter of the bolts 43, so that the bolts 43 can move left and right in the first strip-shaped through cavities 41. Threaded holes for connecting with the bolts 43 are provided on the holder insertion seat 3. An insertion through cavity 31 for accommodating the tungsten needle holder 100 to be inserted is established on the holder insertion seat 3. An insertion port 22 that can be docked with the insertion through cavity 31 is provided on the grinding body 2. The insertion port 22 communicates with the grinding chamber 21.

[0025] When specifically grinding the tungsten needle in this embodiment, if the angle of the holder insertion seat 3 is incorrect, loosen the bolts 43, then move the tungsten needle holder insertion seat 3 up and down while rotating the holder insertion seat 3. After the height and angle meet the requirements, tighten the bolts 43 to fix both the angle and height of the holder insertion seat 3. Subsequently, only need to insert the tungsten needle holder 100 into the insertion through cavity 31, and the top end of the tungsten needle will enter the grinding chamber 21 from the insertion port 22 along the trend and make an oblique contact with the grinding head 11 of the motor main body 1. After the motor main body 1 is started, grinding can be carried out, and during the grinding process, the tungsten needle holder 100 needs to be rotated according to the grinding degree. Among them, for the rotation of the angle of the holder insertion seat 3, it is only rotated within a certain range, and this range is proportional to the width of the first strip-shaped through cavity 41. The larger the width of the first strip-shaped through cavity 41, the larger the adjustable range. Therefore, this embodiment does not limit the specific adjustable angle range.

[0026] Further, when grinding the used tungsten needle, the previous pointed tip needs to be cut off first, so the top end of the tungsten needle needs to be cut. Therefore, to avoid using other equipment again, in this embodiment, a notch groove 23 is provided on the side of the grinding body 2 in the vertical direction. The notch groove 23 communicates with the grinding chamber 21. In this way, the tungsten needle to be cut is vertically placed at the notch groove 23 and then translated into the grinding chamber 21. Subsequently, it contacts the grinding head 11 in the grinding chamber 21. As the pushing process progresses, the cutting can be completed. At the same time, in order to facilitate knowing the position of the grinding head 11 and thus facilitating knowing whether the cutting position is correct, a cutter head mark 24 is provided at the corresponding position of the notch groove 23 relative to the grinding head 11 of the motor main body 1 in this embodiment. In this way, the cutting position can be roughly known.

[0027] Further, after the tungsten needle is cut, the cut may be uneven. If it is uneven, it will affect the subsequent length calibration. Therefore, in this embodiment, jacks 25 with different apertures are provided on the upper end surface of the grinding body 2. The jacks 25 communicate with the grinding chamber 21 and are directly opposite to the grinding head 11 of the motor main body 1. In this way, only need to insert the tungsten needle into the jack 25 of the corresponding size and then make the cut of the tungsten needle contact the grinding head 11, and the grinding can be completed.

[0028] Further, after grinding, the length of the tungsten needle needs to be calibrated, that is, when the tungsten needle holder 100 holds the tungsten needle, the length of the tungsten needle exposed. Therefore, a calibration groove 26 for calibrating the length is provided on the grinding body 21 in this embodiment. The side slot of the calibration groove 26 is located at the edge of the grinding body 2 and is provided with a receiving port 27 for receiving the tungsten needle holder 100. If it is too long, the tungsten needle cannot be fully inserted. If it is too short, the top end of the tungsten needle will not be able to touch the other end of the side of the calibration groove 26. If it is too long or too short, only need to adjust the tungsten needle holder. Of course, this is a function of the tungsten needle holder 100 itself and is not the content that needs to be protected in this embodiment, so it will not be elaborated in detail. Of course, in order to enable the user to know exactly how long it is, a scale 28 is specifically provided on the grinding body 2 and at the side of the calibration groove 26. For the scale, a scale for indicating the angle is also provided on the side to help the user adjust and compare the angle.

[0029] Further, to facilitate the user to directly see the grinding situation in the grinding chamber 21, in this embodiment, an observation window 29 for directly seeing the grinding situation is provided at the position of the grinding chamber 21 on the grinding body 2.

[0030] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
