[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] A needle grinding machine fixture, such as Figures 1 to 3 As shown, it includes a clamping seat 1, and the clamping seat 1 is rotatably arranged on the base 2. Specifically, the base 2 includes a seat body 21 and a seat body 22. The seat body 21 and the seat body 22 are spaced apart. A rotating shaft 8 is arranged at one end of the clamping seat 1, and a rotating shaft 2 9 is arranged at the other end of the clamping seat 1. The rotating shaft 8 and the rotating shaft 2 9 are coaxially arranged. The end of the rotating shaft 8 passes through the seat body 21 and the two are rotatably matched. The end of the rotating shaft 2 9 passes through the seat body 22 and the two are rotatably matched. Through the cooperation of the rotating shaft 8 and the seat body 21 and the cooperation of the rotating shaft 2 9 and the seat body 22, the stability and balance of the clamping seat 1 during the rotation process are guaranteed.

[0025] The clamping seat 1 is driven to rotate by a rotating driving source 1, and the output end of the rotating driving source 1 is connected to the end of a rotating shaft 8, that is, the output end of the rotating driving source 1 rotates and can drive the clamping seat 1 to rotate through the rotating shaft 8. It should be noted that in this embodiment, the rotating driving source 1 is preferably a motor. Of course, other driving sources with a rotating function can also be used. As another solution, the rotating driving source 1 can use a rotating cylinder.

[0026] A support seat 4 is rotatably arranged on the clamping seat 1. Specifically, an axial hole 7 for rotatably cooperating with a rotating shaft 8 is opened on the support seat 4. The end of the rotating shaft 8 is inserted into the axial hole 7 and the two are rotatably cooperating. Through the cooperation between the rotating shaft 8 and the axial hole 7, the support seat 4 can rotate with the rotating shaft 8 as the axis, thereby effectively ensuring the stability of the support seat 4 during the rotation process.

[0027] The support seat 4 is driven to rotate by a rotary drive source 25, and the rotary drive source 25 is installed on the seat body 22. The output end of the rotary drive source 25 is connected to the support seat 4. It should be noted that in this embodiment, the rotary drive source 25 is preferably a rotary cylinder. Of course, other drive sources with a rotation function can also be used. As another solution, the rotary drive source 25 can use a motor.

[0028] A clamping seat 2 3 is slidably provided on the support seat 4 , and a side of the clamping seat 2 3 close to the grinding wheel 14 is provided with an avoidance arc surface 13 to avoid the grinding wheel 14 and avoid interference with the grinding wheel 14 .

[0029] The support seat 4 is provided with a driving member 6 for driving the clamping seat 23 to move, so that the clamping seat 23 is close to or away from the clamping seat 1. Specifically, the driving member 6 includes a cylinder, and the output end of the cylinder passes through the support seat 4 and is connected to the clamping seat 23. The support seat 4 is provided with a slide rail 10, and a slider 11 is slidably connected to the slide rail 10. The clamping seat 23 is connected to the slider 11, that is, the output end of the cylinder is extended or retracted to drive the clamping seat 23 to move along the length direction of the slide rail 10, so that the clamping seat 23 is close to or away from the clamping seat 1, and the slide rail 10 and the slider 11 cooperate to guide the clamping seat 23, so that the clamping seat 23 is more stable when moving.

[0030] It should be noted that when the driving member 6 drives the clamping seat 2 3 to approach the clamping seat 1, the clamping seat 1 can cooperate with the clamping seat 2 3 to clamp the injection needle, so as to ensure the stability of the injection needle during the needle grinding process. After the injection needle completes the needle grinding process, the driving member 6 drives the clamping seat 2 3 away from the clamping seat 1, and the injection needle can move in the horizontal direction to separate from between the clamping seat 1 and the clamping seat 2 3.

[0031] The rotating driving source 25 can drive the support seat 4 to rotate, so that the clamping seat 23 is close to or away from the clamping seat 1, that is, the supporting seat 4 is driven to rotate by the rotating driving source 25, and the supporting seat 4 drives the clamping seat 23 to rotate, thereby making the clamping seat 23 close to or away from the clamping seat 1. It should be noted that when the driving member 6 drives the clamping seat 23 to move away from the clamping seat 1, and the distance between the clamping seat 23 and the clamping seat 1 is too small, it cannot meet the demand for the injection needle to detach. Therefore, the supporting seat 4 is driven to rotate by the rotating driving source 25, and the supporting seat 4 drives the clamping seat 23 to rotate, so that the clamping seat 23 is away from the clamping seat 1, thereby increasing the distance between the clamping seat 23 and the clamping seat 1, ensuring that the injection needle can detach from between the clamping seat 1 and the clamping seat 23, and the clamping seat 23 is driven to rotate by the support seat 4, and then the clamping seat 23 is driven away from the clamping seat 1 by the driving member 6, so as to avoid the clamping seat 23 from contacting the grinding wheel 14, which can effectively ensure the safe operation of the equipment.

[0032] At least two limiting members 12 for limiting the position of the clamping seat 1 are arranged on the support seat 4. The distances between the two limiting members 12 and the clamping seat 1 are different. When the rotating driving source drives the clamping seat 1 to rotate, the clamping seat 1 can respectively abut against the two limiting members 12, thereby limiting the position of the clamping seat 1 after rotation, so as to stably limit the clamping seat 1 to the corresponding position.

[0033] The limiting member 12 includes a bolt 121 and a nut 122. The bolt 121 passes through the support seat 4. The nut 122 is threadedly connected to the bolt 121 and the two are fixed to the support seat 4 in cooperation. The operator can adjust the position of the bolt 121 by rotating the nut 122 to change the distance between the end of the bolt 121 and the clamping seat 1.

[0034] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
