[0085] Please refer to Figure 1 , an embodiment of the present application provides a fluid polishing jig 100 for clamping a workpiece 900 to be polished, so as to facilitate the fluid polishing machine (not shown in the figure) to perform fluid polishing treatment on the workpiece 900. Among them, the workpiece 900 may be a medical tool shank, a tool, an ornament, etc. For the convenience of understanding and description, in the embodiment of the present application, the workpiece 900 is a medical tool shank, and the first direction is defined as Figure 1 and Figure 2 the Z-axis direction shown in Figure 1 and Figure 2 the X-axis direction shown in

[0086] Please refer to Figure 1 and Figure 2, in this embodiment, the fluid polishing fixture 100 includes a connecting member 10, a base assembly 2, a plurality of first heightening members 50, a positioning assembly 60, and a pressing assembly 70.

[0087] The connecting member 10 extends along a first direction, and the connecting member 10 has a first end 11 and a second end 12 that are oppositely arranged along the first direction. The first end 11 and the second end 12 are respectively the two ends of the connecting member 10 along the first direction.

[0088] The base assembly 2 is disposed at the first end 11.

[0089] A plurality of first heightening members 50 are slidably sleeved on the connecting member 10 and are located on the side of the base assembly 2 facing the second end 12. Each first heightening member 50 is provided with a through hole 51 extending along the first direction, and the plurality of through holes 51 are sequentially communicated and are disposed opposite to each other.

[0090] The positioning assembly 60 is slidably sleeved on the connecting member 10 and is located on the side of the plurality of first heightening members 50 facing the second end 12. The positioning assembly 60 is provided with an insertion hole 611 extending along the first direction and disposed opposite to the plurality of through holes 51. The workpiece 900 to be polished passes through the insertion hole 611 and is inserted into the plurality of through holes 51.

[0091] The pressing assembly 70 is disposed at the second end 12 and abuts against the positioning assembly 60. The pressing assembly 70 includes a pressing member 71, a first fixing member 72, and a second fixing member 73. The pressing member 71 is slidably sleeved on the second end 12 and abuts against the positioning assembly 60. One end of the first fixing member 72 abuts against the end of the pressing member 71 away from the positioning assembly 60. The other end of the first fixing member 72 passes through the pressing member 71 along the first direction and is connected to the second end 12. The first fixing member 72 is used to push and press the pressing member 71 to move along the first direction towards the positioning assembly 60, so that the pressing member 71 presses the positioning assembly 60. The second fixing member 73 passes through the pressing member 71 along a second direction and is connected to the second end 12. The second fixing member 73 is used to limit the movement of the pressing member 71 when the pressing member 71 moves to a preset position.

[0092] Please refer to Figure 7 and Figure 8, in this embodiment, both the first fixing member 72 and the second fixing member 73 are bolts. A sliding groove 711 extending in the first direction is formed on the side of the pressing member 71 facing the positioning assembly 60. The second end 12 is slidably inserted into the sliding groove 711. A stop hole 712 extending in the first direction and communicating with the sliding groove 711 is formed on the side of the pressing member 71 away from the positioning assembly 60. An assembly hole 713 communicating with the sliding groove 711 is formed on the side wall of the pressing member 71. One end of the first fixing member 72 abuts against the bottom of the stop hole 712, and the other end of the first fixing member 72 passes through the stop hole 712 and is threadedly connected to the second end 12. By screwing the first fixing member 72, the distance that the first fixing member 72 pushes and presses the pressing member 71 to move in the first direction can be adjusted. After the pressing member 71 moves a preset distance, the second fixing member 73 passes through the assembly hole 713 and is threadedly connected to the second end 12.

[0093] When it is necessary to clamp the workpiece 900 to be polished, the workpiece 900 to be polished is inserted through the insertion hole 611 and into a plurality of through holes 51. One end of the workpiece 900 to be polished extends out of the insertion hole 611. Then, the pressing member 71 is sleeved on the second end 12 of the connecting member 10 and abuts and presses against the positioning assembly 60. Finally, the first fixing member 72 and the second fixing member 73 are used to fix the pressing member 71 to the second end 12. When it is necessary to polish the workpiece 900 to be polished, the first end 11 of the connecting member 10 and the stop hole 712 of the pressing member 71 are respectively connected to a polishing machine. The polishing machine drives the fluid polishing fixture 100 to rotate forward and backward to polish one end of the workpiece 900 to be polished that needs to be polished. Since the first fixing member 72 and the second fixing member 73 fix the pressing member 71 to the second end 12 axially and radially respectively, when the fluid polishing fixture 100 rotates forward and backward, the second fixing member 73 can limit the relative movement of the first fixing member 72 and the connecting member 10, and the first fixing member 72 and the second fixing member 73 are stressed simultaneously, which is beneficial to reducing the risk of loosening and breaking of the top screw.

[0094] In this embodiment, the fluid polishing machine can be a abrasive fluid polishing machine, which is beneficial to improving the polishing effect on the workpiece 900.

[0095] Please refer to Figure 3 and Figure 4, in this embodiment, the side wall of the connecting member 10 is provided with a limiting surface 13 extending in the first direction. Each first heightening member 50 is provided with a through hole 52 extending in the first direction. The inner wall of each through hole 52 is provided with an abutting surface 521 extending in the first direction. The connecting member 10 slidably passes through a plurality of through holes 52, and the limiting surface 13 abuts against a plurality of abutting surfaces 521 to limit the rotation of the plurality of first heightening members 50 relative to the connecting member 10. In this way, the probability that the workpiece 900 to be polished is damaged due to the rotation of the plurality of first heightening members 50 relative to the connecting member 10 when the polishing machine polishes the workpiece 900 to be polished can be effectively reduced.

[0096] In this embodiment, the adjacent ends of any two adjacent first heightening members 50 are engaged with each other in a concave-convex manner for positioning. In this way, it is beneficial to improve the accuracy of installing a plurality of first heightening members 50, and the probability that the workpiece 900 to be polished is damaged due to the relative movement between the plurality of first heightening members 50 when the polishing machine polishes the workpiece 900 to be polished can be effectively reduced.

[0097] In this embodiment, a splicing groove 53 is formed on one side of each first heightening member 50 facing the first end 11. A positioning protrusion 531 protrudes from the bottom of each splicing groove 53. A splicing protrusion 54 protrudes from one side of each first heightening member 50 facing the second end 12. A limiting groove 541 is formed on each splicing protrusion 54. The splicing protrusion 54 is engaged with the adjacent splicing groove 53 in a concave-convex manner, and the positioning protrusion 531 is inserted into the adjacent limiting groove 541 to position two adjacent first heightening members 50. Each through hole 51 passes through the corresponding splicing protrusion 54 and the bottom of the corresponding splicing groove 53 and is located on one side of the corresponding positioning protrusion 531 and the corresponding limiting groove 541. When installing a plurality of first heightening members 50, the splicing protrusion 54 is engaged with the adjacent splicing groove 53 in a concave-convex manner for primary positioning, and the positioning protrusion 531 is inserted into the adjacent limiting groove 541 for secondary positioning, which is beneficial to improve the accuracy of installing a plurality of first heightening members 50, and the probability that the workpiece 900 to be polished is damaged due to the relative movement between the plurality of first heightening members 50 when the polishing machine polishes the workpiece 900 to be polished can be effectively reduced. In addition, by arranging that each through hole 51 passes through the corresponding splicing protrusion 54 and the bottom of the corresponding splicing groove 53, the adjacent two through holes 51 are hermetically protected when the splicing protrusion 54 is engaged with the adjacent splicing groove 53, so that the probability that abrasive grains enter the through hole 51 and damage the non-polished part of the workpiece 900 to be polished can be reduced.

[0098] In this embodiment, each through hole 52 passes through the corresponding splicing protrusion 54 and the bottom of the corresponding splicing groove 53 and is located on one side of the corresponding positioning protrusion 531 and the corresponding limiting groove 541, and each through hole 52 is arranged at an interval from the corresponding perforation 51. Thus, when the splicing protrusion 54 is in concave-convex fit with the adjacent splicing groove 53, the two adjacent through holes 52 can also be hermetically protected, thereby reducing the probability of abrasive particles entering the through holes 52 and damaging the connecting member 10.

[0099] In this embodiment, the base assembly 2 includes a support member 20, a guiding unit 30, and an elastic member 40. The support member 20 is arranged at the first end 11; the guiding unit 30 is slidably sleeved on the connecting member 10 and is located between the support member 20 and the plurality of first heightening members 50. A limiting hole 321 extending along the first direction and facing the plurality of perforations 51 is formed on one side of the guiding unit 30 away from the support member 20. The limiting hole 321 is used to receive and limit one end of the workpiece 900 to be polished away from the pressing assembly 70, thereby facilitating improving the accuracy of the fluid polishing fixture 100 in clamping the workpiece 900 to be polished; the elastic member 40 is arranged between the support member 20 and the guiding unit 30, and two ends of the elastic member 40 are respectively connected to the support member 20 and the guiding unit 30. When the fluid polishing fixture 100 clamps the workpiece 900 to be polished, by screwing the first fixing member 72, the first fixing member 72 squeezes the pressing member 71, and the pressing member 71 pushes the positioning assembly 60 to move towards the first end 11. At this time, the elastic member 40 is compressed, and the elastic member 40 elastically supports the guiding unit 30 and the plurality of first heightening members 50, thereby facilitating improving the tightness of the cooperation of the plurality of first heightening members 50. In addition, when the fluid polishing fixture 100 clamps workpieces 900 to be polished with different lengths, only the number of the first heightening members 50 needs to be correspondingly adjusted according to the length of the workpiece 900 to be polished, and then the elastic member 40 and the pressing assembly 70 are made to cooperate to clamp the plurality of first heightening members 50, thereby improving the versatility of the fluid polishing fixture 100.

[0100] In some other embodiments, the fluid polishing fixture 100 further includes a second heightening member (not shown in the figure). The second heightening member is slidably sleeved on the connecting member 10 and is located on one side of the plurality of first heightening members 50 or between any two adjacent first heightening members 50. The second heightening member has the same structure as the first heightening member 50, and the length of the second heightening member along the first direction is greater than or less than the length of the first heightening member 50 along the first direction. Thus, it is convenient to reasonably match the second heightening member with the plurality of first heightening members 50 to meet the clamping requirements of workpieces 900 to be polished with different lengths.

[0101] It can be understood that the number of the second heightening members can be multiple, so as to conveniently select an appropriate number of first heightening members 50 and an appropriate number of second heightening members for matching to meet the clamping requirements of workpieces 900 to be polished with different lengths. The embodiments of the present application do not make specific limitations thereto.

[0102] Please further refer to Figure 5 and Figure 6 In this embodiment, the support member 20 is provided with an assembly hole 21 extending in the first direction. The first end 11 of the connecting member 10 passes through the assembly hole 21. A clamping groove 22 communicating with the assembly hole 21 is provided on the side of the support member 20 away from the guiding unit 30. The fluid polishing jig 100 further includes a clamping member 80. The clamping member 80 passes through the first end 11 and is clamped with the clamping groove 22, so as to facilitate the disassembly and assembly of the support member 20.

[0103] In this embodiment, the guiding unit 30 includes a stopper 31 and a guiding member 32. The stopper 31 is slidably sleeved on the connecting member 10 and is located on the side of the support member 20 facing the second end 12. Two ends of the elastic member 40 are respectively connected to the support member 20 and the stopper 31. The stopper 31 is provided with a first sliding hole 311 for the connecting member 10 to pass through. The inner wall of the first sliding hole 311 has a first abutting surface 3111 abutting against the limiting surface 13. A stopper groove 312 for stopping the workpiece 900 to be polished is provided on the side of the stopper 31 away from the support member 20. The guiding member 32 is slidably sleeved on the connecting member 10 and is located on the side of the stopper 31 facing the second end 12. A limiting hole 321 is provided in the guiding member 32 and is disposed opposite to the stopper groove 312. The guiding member 32 is further provided with a second sliding hole 322 for the connecting member 10 to pass through. The inner wall of the second sliding hole 322 has a second abutting surface 3221 abutting against the limiting surface 13. One end of the guiding member 32 facing the adjacent first heightening member 50 is in concave-convex fit with the adjacent first heightening member 50 for positioning. By providing the first abutting surface 3111 and the second abutting surface 3221 to abut against the limiting surface 13, the probability that the stopper 31 and the guiding member 32 rotate relative to the connecting member 10 during the polishing process of the workpiece 900 to be polished by the polishing machine, causing damage to the workpiece 900 to be polished, can be effectively reduced. By providing the stopper 31 and the guiding member 32 as a split structure, it is convenient to clean the debris and dust entering the limiting hole 321. By providing one end of the guiding member 32 facing the adjacent first heightening member 50 to be in concave-convex fit with the adjacent first heightening member 50 for positioning, it is beneficial to improve the accuracy of assembling the first heightening member 50 and the guiding unit 30, and can effectively reduce the probability that the workpiece 900 to be polished is damaged due to relative movement between the first heightening member 50 and the guiding unit 30 during the polishing process of the workpiece 900 to be polished by the polishing machine.

[0104] In this embodiment, the structure of one end of the guiding member 32 facing the adjacent first heightening member 50 is the same as the structure of the first heightening member 50 facing the second end 12, so as to facilitate the accurate assembly of the guiding member 32 and the first heightening member 50.

[0105] In this embodiment, the end portions of the stopper 31 and the alignment member 32 that are close to each other are in concave-convex fit to seal the first sliding hole 311 and the second sliding hole 322, thereby reducing the probability of abrasive particles entering the first sliding hole 311 and the second sliding hole 322 and damaging the connecting member 10.

[0106] In this embodiment, an assembly protrusion 23 protrudes from one end of the support member 20 facing the stopper 31. The assembly hole 21 passes through the assembly protrusion 23. A first limiting groove 231 spaced from the assembly hole 21 is formed on one side of the assembly protrusion 23 facing the stopper 31. An assembly groove 313 that is in concave-convex fit with the assembly protrusion 23 is formed on one side of the stopper 31 facing the support member 20. The first sliding hole 311 passes through the bottom of the assembly groove 313. A second limiting groove 3131 that is disposed opposite to the first limiting groove 231 is formed on the bottom of the assembly groove 313. Two ends of the elastic member 40 are respectively inserted into the first limiting groove 231 and the second limiting groove 3131. In this way, it is beneficial to improve the accuracy of installing the elastic member 40. In addition, the concave-convex fit between the assembly protrusion 23 and the assembly groove 313 facilitates hiding the elastic member 40 and sealing the assembly hole 21, the first sliding hole 311, the first limiting groove 231, and the second limiting groove 3131.

[0107] Please refer back to Figure 7 and Figure 8In this embodiment, the positioning assembly 60 includes a first positioning member 61 and a second positioning member 62. The first positioning member 61 is slidably sleeved on the connecting member 10 and is located on the side of the plurality of first padding members 50 facing the second end 12. An insertion hole 611 is provided on the first positioning member 61. The inner wall of the insertion hole 611 is provided with a first positioning groove 6111 extending along the first direction. The first positioning member 61 is also provided with a first connecting hole 612 for the connecting member 10 to pass through. The inner wall of the first connecting hole 612 has a first limiting surface 6121 abutting against the limiting surface 13. One end of the first positioning member 61 facing the adjacent first padding member 50 is positioned by concave-convex cooperation with the adjacent first padding member 50. The first positioning member 61 is provided with a receiving groove 613 on the side facing the second end 12. The first connecting hole 612 and The insertion holes 611 all pass through the bottom of the receiving groove 613; the second positioning member 62 is slidably mounted on the connecting member 10 and is located on the side of the first positioning member 61 facing the second end 12, the second positioning member 62 is provided with a second connecting hole 621 for the connecting member 10 to pass through, the second positioning member 62 extends into the receiving groove 613 at one end facing the first positioning member 61, the second positioning member 62 is abutted against the clamping member 71 at one end away from the first positioning member 61, and a second positioning groove 622 is provided on the peripheral side wall of the second positioning member 62 at one end facing the first positioning member 61, which is directly opposite to the first positioning groove 6111, and the first positioning groove 6111 and the second positioning groove 622 cooperate to position the workpiece 900 to be polished. By arranging the first limiting surface 6121 and the second limiting surface 6211 to abut against the limiting surface 13, the probability of the first positioning member 61 and the second positioning member 62 rotating relative to the connecting member 10 to damage the workpiece 900 to be polished can be effectively reduced when the polishing machine performs a polishing process on the workpiece 900 to be polished, and the first positioning member 61 is arranged to face one end of the adjacent first padding member 50 to be positioned with the adjacent first padding member 50 in a concave-convex manner, which is conducive to improving the accuracy of assembling the first padding member 50 with the first positioning member 61. It can also effectively reduce the probability of damage to the workpiece 900 to be polished due to the relative movement between the first pad 50 and the positioning assembly 60 when the polishing machine is polishing the workpiece 900 to be polished; by arranging the second positioning member 62 to extend into the receiving groove 613 toward one end of the first positioning member 61, and opening a first positioning groove 6111 on the inner wall of the insertion hole 611, and opening a second positioning groove 622 on the peripheral side wall of the second positioning member 62 toward one end of the first positioning member 61, it is convenient to accurately position the workpiece 900 to be polished.

[0108] In this embodiment, the structure of the end of the first positioning member 61 facing the adjacent first padding member 50 is the same as the structure of the first padding member 50 facing the first end 11 , thereby facilitating accurate assembly of the first positioning member 61 and the first padding member 50 .

[0109] In this embodiment, the first positioning groove 6111 passes through the groove wall of the receiving groove 613 and extends to the side of the first positioning member 61 facing the second end 12. The size of a portion of the first positioning groove 6111 close to the second end 12 is smaller than the size of other portions of the first positioning groove 6111. A portion of the first positioning groove 6111 close to the second end 12 cooperates with the second positioning groove 622 to precisely position the workpiece 900 to be polished, thereby facilitating improving the accuracy of positioning the workpiece 900 to be polished.

[0110] In this embodiment, the size of the end of the second positioning groove 622 away from the second end 12 gradually increases, so as to facilitate the second positioning groove 622 to quickly abut against the workpiece 900 to be polished.

[0111] In this embodiment, the positioning assembly 60 further includes an extrusion member 63, which is rotatably disposed in the receiving groove 613 and is located on the side of the second positioning member 62 facing the first positioning member 61. The extrusion member 63 is provided with a rotation hole 631 for the connection member 10 to pass through, and the peripheral side wall of the extrusion member 63 is provided with a avoidance groove 632. When the extrusion member 63 is screwed so that the avoidance groove 632 is directly opposite to the insertion hole 611, the avoidance groove 632 avoids the workpiece 900 to be polished, thereby facilitating the placement and removal of the workpiece 900 to be polished; when the extrusion member 63 is screwed so that the avoidance groove 632 is misaligned with the insertion hole 611, the peripheral side wall of the extrusion member 63 presses the workpiece 900 to be polished against the first positioning groove 6111, thereby effectively preventing the workpiece 900 to be polished from shaking during polishing and affecting the polishing quality.

[0112] In this embodiment, a limiting protrusion 6311 is convexly provided on the inner wall of the rotating hole 631, and the limiting protrusion 6311 is used to abut against the limiting surface 13 when the avoiding groove 632 is directly opposite to the insertion hole 611, so as to limit the extrusion member 63 from continuing to rotate in one rotation direction. In this way, it is convenient to make the avoiding groove 632 and the insertion hole 611 accurately face each other by screwing the rotating hole 631.

[0113] In this embodiment, a screwing scale 614 is provided on one side of the first positioning member 61 facing the second end 12, and the screwing scale 614 is used to mark the position to which the limiting protrusion 6311 moves. Specifically, the screwing scale 614 includes two scale positions 1 and 2. When the limiting protrusion 6311 moves to the scale position 1, it means that the limiting protrusion 6311 is in contact with the limiting surface 13, and the avoidance groove 632 is completely opposite to the insertion hole 611. When the limiting protrusion 6311 moves to the scale position 2, it means that the avoidance groove 632 is completely offset from the insertion hole 611. In this way, it is convenient to accurately screw the extrusion member 63.

[0114] In this embodiment, a clamping groove 623 is formed on one side of the second positioning member 62 facing the pressing member 63, and a clamping protrusion 633 protrudes from one side of the pressing member 63 facing the second positioning member 62. When the fluid polishing jig 100 clamps the workpiece 900 to be polished, first pass the workpiece 900 through the insertion hole 611 and multiple through holes 51 and extend it into the limiting hole 321, then place the pressing member 63 into the receiving groove 613, and screw the pressing member 63 to press the workpiece 900 to be polished. After that, place the second positioning member 62 into the receiving groove 613 so that the clamping protrusion 633 is inserted into the clamping groove 623. Finally, install the pressing assembly 70 on the second end 12 and press the second positioning member 62. Among them, the clamping protrusion 633 facilitates applying force when the operator screws the pressing member 63. The cooperation between the clamping protrusion 633 and the clamping groove 623 can limit the rotation of the pressing member 63, thereby avoiding the rotation of the pressing member 63 when the workpiece 900 to be polished is polished and unable to press the workpiece 900 to be polished. Moreover, the cooperation between the clamping protrusion 633 and the clamping groove 623 facilitates accurately aligning the first positioning groove 6111 and the second positioning groove 622.

[0115] In this embodiment, both the insertion hole 611 and the limiting hole 321 are multiple and correspond one by one. The through holes 51 formed on each first padding member 50 are also multiple. The multiple through holes 51 formed on each first padding member 50 correspond to the multiple insertion holes 611 and the multiple limiting holes 321 respectively one by one. In this way, it is convenient for the fluid polishing jig 100 to clamp multiple workpieces 900 to be polished at the same time.

[0116] In summary, the fluid polishing jig 100 of the embodiment of the present application is provided with multiple first padding members 50 and a positioning assembly 60 sleeved on the connecting member 10, and through holes 51 extending in the first direction are respectively formed on each first padding member 50, and insertion holes 611 extending in the first direction and facing the multiple through holes 51 are formed on the positioning assembly 60, which is convenient for carrying the workpiece 900 to be polished; by setting the pressing member 71 to press the positioning assembly 60, and setting the first fixing member 72 and the second fixing member 73 to fix the pressing member 71 and the second end 12 of the connecting member 10 in the first direction and the second direction respectively, the first fixing member 72 and the second fixing member 73 fix the pressing member 71 and the second end 12 of the connecting member 10 axially and radially respectively. When the fluid polishing jig 100 rotates forward and backward under the drive of the fluid polishing machine, the second fixing member 73 can limit the relative movement of the first fixing member 72 and the connecting member 10, and the first fixing member 72 and the second fixing member 73 are stressed at the same time, which is beneficial to reducing the risk of loosening and breaking of the top screw.
