The technical solution of the first embodiment effectively solves the problem of deviation in the grinding angle size in the prior art during the grinding of the tungsten needle.

[0034] like Figure 2 and Figure 4 As shown, in the technical solution of the first embodiment, the fixing structure 33 includes a fixing portion 331 and a connecting portion 332, the clamping structure 34 is connected to the connecting portion 332, the fixing portion 331 is sleeved at the connection between the clamping structure 34 and the connecting portion 332, and the connecting portion 332 is rotatably connected to the mounting seat structure 32. The fixing portion 331 fixes the clamping structure 34 so that the clamping structure 34 is in a clamping state, and the rotation of the connecting portion 332 drives the clamping structure 34 to rotate, thereby driving the tungsten needle to rotate along the axis, so that the tungsten needle is polished at all circumferential locations.

[0035] like Figure 2 and Figure 4 As shown, in the technical solution of the first embodiment, the clamping structure 34 includes a first clamping portion 341 and a second clamping portion 342, the first clamping portion 341 includes a threaded section 3411 and a clamping section 3412, the threaded section 3411 is connected to the connecting portion 332, and the tungsten needle to be polished is arranged between the first clamping portion 341 and the second clamping portion 342.

[0036] like Figure 2 and Figure 4As shown, in the technical solution of the first embodiment, along the direction from approaching to away from the threaded section 3411, the size of the end of the clamping section 3412 away from the threaded section 3411 increases continuously, and the size of the end of the second clamping portion 342 away from the threaded section 3411 increases continuously. The clamping section 3412 is in a semi-truncated cone shape, the second clamping portion 342 is in a semi-truncated cone shape, the clamping section 3412 has a limiting hole, and the second clamping portion 342 has a limiting column arranged corresponding to the limiting hole, the limiting column is inserted into the upper limiting hole, and the two together form a frustum shape. The maximum diameter of the cone is larger than the inner diameter of the fixing part 331. When the threaded section 3411 is tightened, the cone drives the fixing part 331 to move toward the connecting part 332 and is partially sleeved on the connecting part 332. The connecting part 332 has a limiting part, and the diameter of the limiting part is larger than the inner diameter of the fixing part 331. The fixing part 331 stops moving under the joint action of the limiting part and the cone, and the inner diameter of the fixing part 331 limits the clamping section 3412 and the second clamping part 342, so that the two remain in a clamped state, and the tungsten needle is located between the two. The setting of the limiting hole and the limiting column prevents the second clamping part 342 from moving along the axis of the fixing part 331 and separating from the fixing part 331.

[0037] like Figure 2 and Figure 4 As shown, in the technical solution of the first embodiment, the fixing part 331 has a limiting groove 3311, the first clamping part 341 has a limiting protrusion 3413 matched with the limiting groove 3311, the limiting protrusion 3413 is connected to the clamping section 3412, and the limiting protrusion 3413 is arranged in the limiting groove 3311. The limiting groove 3311 is located on the side wall of the fixing part 331. The setting of the limiting groove 3311 and the limiting protrusion 3413 enables the first clamping part 341 to be rotated when the fixing part 331 is rotated, thereby rotating the threaded section 3411 to control the tightness of the threaded connection, and the first clamping part 341 and the second clamping part 342 are loosened when the thread is loosened, and the tungsten needle can be replaced, and the thread is tightened, and the first clamping part 341 and the second clamping part 342 are close to each other to clamp the tungsten needle. The limiting protrusion 3413 and the limiting groove 3311 enable the rotating fixing part 331 to control the clamping structure 34 to switch between the clamping state and the waiting clamping state, which is convenient for the staff to operate.

[0038] like Figure 2 and Figure 4As shown, in the technical solution of the first embodiment, the fixed structure 33 also includes a hand wheel 333, the hand wheel 333 is connected to the end of the connecting part 332 away from the clamping structure 34, and the axis of the hand wheel 333 coincides with the axis of the connecting part 332. The hand wheel 333 includes a wheel body and a handle, the wheel body is connected to the connecting part 332, and the axes of the two coincide, the handle is connected to the wheel body and is located on the side of the wheel body away from the connecting part 332, and there is a predetermined distance between the handle and the center of the wheel body, and the operation of the handle makes the wheel body rotate along its axis, thereby controlling the tungsten needle to rotate along its own axis. The setting of the handle makes it easier for the staff to rotate the tungsten needle, further reducing the difficulty of operation.

[0039] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the horizontal driving structure 31 includes a slide rail 311 and a slider 312, the slider 312 is movably connected to the slide rail 311, and the mounting seat structure 32 is connected to the slider 312. The slider 312 moves along the extension direction of the slide rail 311, and the mounting seat structure 32 moves with the movement of the slider 312. The horizontal driving structure 31 drives the mounting seat structure 32 to approach or move away from the grinding assembly 20, thereby controlling the tungsten needle to approach or move away from the grinding assembly 20. When grinding is required, the tungsten needle is controlled to approach the grinding assembly 20 for grinding. After the grinding is completed, the tungsten needle is controlled to move away from the grinding assembly 20 to replace the tungsten needle, so as to avoid the problem of staff contacting the grinding assembly during the replacement process and causing injuries. The slider 312 also includes a rotatable base, which includes a double layer, the lower layer is movably connected to the slide rail 311, the upper layer is rotatably connected to the lower layer, the diameter of the lower layer is larger than the upper layer, and the lower layer is provided with a scale line to read the rotation angle of the upper layer. The setting of this structure can control the grinding angle of the tungsten needle by changing the rotation angle of the upper layer, making the whole tungsten needle grinder more free.

[0040] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the horizontal driving structure 31 also includes a screw 313 and a sleeve 314. The sleeve 314 is connected to the slide rail 311. The sleeve 314 has a threaded hole matched with the screw 313. The screw 313 is inserted into the threaded hole. The screw 313 is rotatably connected to the slider 312. The sleeve 314 is fixed on the slide rail 311. The axis of the sleeve 314 is arranged parallel to the slide rail 311. A bearing is arranged at the connection between the screw 313 and the slider 312. The inner ring of the bearing and the screw 313 are interference fit, and the outer ring of the bearing and the slider 312 are interference fit. The screw 313 moves in the horizontal direction while rotating, thereby driving the movement of the slider 312. An operating part is arranged at one end of the screw 313 away from the slider 312. The setting of the operating part is convenient for the staff to rotate the screw 313 to control the movement of the slider 312.

[0041] like Figure 2 and Figure 3 As shown, in the technical solution of the first embodiment, the frame assembly 10 includes a frame 11 and a fixed seat 12, the fixed seat 12 is connected to the frame 11, the motor 22 is rotatably connected to the fixed seat 12, and the fixed seat 12 is provided with an angle scale line. The outer shell of the motor 22 is provided with a marking line, and the angle that the motor 22 needs to rotate is calculated according to the size of the grinding angle required for the tungsten needle to be polished, and the angle is read by observing the marking line and the angle scale line, and the motor 22 is rotated to a suitable position. The setting of the fixed seat 12 and the angle scale line facilitates the staff to accurately control the angle of rotation of the motor 22, and then control the angle between the grinding structure 21 and the tungsten needle, so as to obtain a tungsten needle of the required size. In the technical solution of the first embodiment, the grinding structure 21 uses a grinding wheel, the working surface of the grinding wheel is parallel to the output shaft of the motor 22, and the angle between the axis of the output shaft of the motor 22 and the axis of the tungsten steel is the size of the grinding angle.

[0042] like Figure 2 and Figure 3 As shown, in the technical solution of the first embodiment, a fastener is provided on the motor 22, and the fastener abuts against the fixing seat 12. When the fastener is tightened, the motor 22 rotates and is subjected to the friction between the fastener and the fixing seat 12, so that the motor 22 is not easy to rotate, thereby avoiding the change of the grinding angle caused by the rotation of the motor 22 during the grinding process; when the fastener is loosened, the motor 22 rotates relative to the fixing seat 12, so as to facilitate the adjustment of the grinding structure 21 to a suitable position.

[0043] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that in the technical solution of the second embodiment, the grinding assembly 20 uses an angle grinder, and the working surface of the angle grinder is perpendicular to the axis of the motor 22. At this time, the angle between the axis of the motor 22 and the axis of the tungsten needle minus 90° is the grinding angle. The second embodiment is a substitute for the first embodiment. In actual use, it can be set according to the local materials on the workshop site.

[0044] Based on the above, it can be known that the tungsten needle is fixed by using a clamping device (clamping structure 34) and the grinding of the tungsten needle is achieved by rotating the grinder (grinding assembly 20) and the hand-cranked tungsten needle fixture (fixing structure 33 and clamping structure 34). This solves the current problem that the tungsten needle has multiple hazards, low manual grinding efficiency, and high risk factor. The tungsten needle is clamped in the tungsten needle chuck (clamping structure 34), and the slider in the seamless steel pipe with an inner diameter of 6MM and an outer diameter of 13MM is adjusted to the required angle. The grinder can rotate the base to the required angle, and all parts on the slider 312 are moved parallel to the right by manually adjusting the screw, so that the tungsten needle contacts the grinder, and the rotating hand wheel (hand wheel 333) is manually rotated to make the tungsten needle rotate clockwise for grinding. According to actual needs, the base can be rotated to the desired angle according to the base scale slider 312 to change the angle and range of all parts on the slider 312; (a motor can be installed to achieve automatic angle adjustment) According to the base scale adjustment diagram, the grinder can rotate the base to the desired angle to change the angle and range of all parts on the slider 312; (a motor can be installed to achieve automatic angle adjustment) Clockwise rotation of the rotating hand wheel in the diagram can drive the tungsten needle to rotate; Adjusting the manual adjustment screw 313 can make all parts on the slider 312 move parallel to the right or left; Mechanical grinding and existing manual grinding have the following beneficial effects: manual grinding has low efficiency and high risk factor, and the tungsten needle is a radioactive material. During grinding, you may come into contact with substances such as tungsten dust, tungsten oxide or tungsten alloy. These substances accumulate in the human body, and long-term exposure may cause damage to multiple organs such as the lungs, liver, and kidneys, leading to the occurrence of multiple chronic diseases and even cancer.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution of the present application.

It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application.
