Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0029] Please refer to Figures 1 to 5 The utility model proposes a spring melting head fixture 100 for positioning a spring, comprising: a clamping mechanism 10, wherein the clamping mechanism 10 is provided with a clamping groove (not shown in the figure), wherein the clamping groove is used to clamp the spring so that the end of the spring is at least partially exposed outside the clamping groove; and a positioning mechanism 20, wherein the positioning mechanism 20 comprises a fixing member 21 and a positioning component 22, wherein the fixing member 21 is provided on the clamping mechanism 10, wherein the positioning component 22 is movably provided on the fixing member 21 and is away from or close to the clamping groove, wherein the positioning component 22 is provided with a positioning head 221, wherein the positioning head 221 is provided with a positioning groove (not shown in the figure); wherein the positioning mechanism 20 has a positioning state in which the positioning component 22 is abutted against the clamping mechanism 10, wherein in the positioning state, the positioning groove is aligned with the end of the spring so that the end of the spring extends out a preset distance.
[0030] Specifically, the spring melting head fixture 100 can cooperate with the laser mechanism, the spring melting head fixture 100 positions the spring end, and the laser mechanism performs melting head processing on the spring end. The spring melting head fixture 100 includes a clamping mechanism 10 and a positioning mechanism 20. The clamping mechanism 10 is used to clamp the spring and expose the end of the spring outside the clamping groove; the positioning mechanism 20 is used to position the spring. The positioning mechanism 20 can accurately control the extension distance of the spring end so that the subsequent laser melting head can better control the size of the melting head and improve the melting head accuracy.
[0031] The clamping mechanism 10 is provided with a clamping groove, which can clamp the spring. The clamping groove can be composed of two half grooves 111 or a whole circular groove. The spring is manually clamped in the clamping groove, and the end of the spring is kept at least partially exposed to the outside of the clamping groove; at this time, the spring can move under the action of external force.
[0032] The positioning mechanism 20 is configured as a fixing part 21 and a positioning assembly 22. The fixing part 21 is fixed on the clamping mechanism 10. The positioning assembly 22 is movably arranged and can be close to or away from the clamping groove. The positioning assembly 22 is provided with a positioning head 221. The positioning head 221 is abutted against the clamping mechanism 10. The extension distance of the end of the spring is controlled by the positioning groove on the positioning head 221, so that the end of the spring is extended to a preset distance.
[0033] When the positioning assembly 22 positions the extension distance of the spring end, the positioning head 221 is pressed against the clamping mechanism 10, and the positioning groove of the positioning head 221 is aligned with the end of the spring, so that the bottom wall of the positioning groove presses against the spring, so that the end of the spring extends out a preset distance. The position of the positioning head 221 pressed against the clamping mechanism 10 is fixed, and the extension distance of the spring end can be controlled by controlling the depth of the positioning groove, thereby achieving precise control of the height of the exposed spring end, and being able to accurately control the size of the spring end fusion head, thereby improving the precision of the fusion head.
[0034] The positioning state of the positioning mechanism 20 is the state in which the positioning head 221 positions the spring end. The positioning mechanism 20 also has a disengaged state in which the positioning component 22 is away from the clamping mechanism 10. In the disengaged state, the positioning component 22 is away from the clamping groove, and the spring can be placed or the melting head can be performed.
[0035] Melting the spring tip can prevent blood vessel damage during use. The distance the spring end extends determines the size of the spring end melt tip. The preset distance is the distance set according to the size of different medical springs and actual needs. The diameter of the melt tip is usually related to the diameter of the spring wire and can be larger than the diameter of the spring wire to ensure smooth edges and reduce the risk of trauma. For example, the size of the melt tip will be larger for springs in larger external fixation or support devices.
[0036] The technical solution of the utility model is to set a positioning mechanism 20, and the positioning head 221 of the positioning mechanism 20 can be supported on the clamping mechanism 10, and the end of the spring is positioned through the positioning groove to control the extension distance of the spring end, so that the spring end extends a preset distance, thereby being able to well control the size of the spring fuse and improve the accuracy of the spring fuse.
[0037] In an embodiment of the utility model, the positioning assembly 22 includes a transverse support column 222 and a positioning member 223. The transverse support column 222 is movably arranged on the fixing member 21 along the horizontal direction. The positioning member 223 is movably passed through the transverse support column 222 along the radial direction of the transverse support column 222. The positioning member 223 has the positioning head 221.
[0038] In detail, the positioning member 223 can be moved in the horizontal direction by being connected to the transverse support column 222, close to or away from the clamping groove. At the same time, through the movable adjustment of the transverse support column 222, the horizontal movement of the positioning member 223 can be accurately aligned with the clamping groove, ensuring correct alignment and cooperation with the clamping groove. The design of the transverse movement of the positioning member 223 along the transverse support column 222 makes the operation more convenient.
[0039] At the same time, the positioning member 223 is vertically penetrated on the horizontal support column 222, and the positioning member 223 is movably arranged vertically, so that the positioning member 223 can move horizontally and vertically, which is convenient for aligning the clamping groove and making the positioning head 221 abut against the clamping mechanism 10, so that the positioning groove is aligned with the end of the spring.
[0040] In an embodiment of the utility model, the fixing member 21 includes a vertical support column 211, which is vertically fixedly connected to the clamping mechanism 10, and the transverse support column 222 is movably arranged on the vertical support column 211 along the radial direction of the vertical support column 211.
[0041] It is worth noting that the fixing member 21 is configured as a vertical support column 211, which is convenient for connecting the transverse support column 222 and increasing the overall stability of the positioning mechanism 20, thereby making the movement of the transverse support column 222 and the positioning member 223 more stable.
[0042] In addition, if Figure 1 A limiting protrusion 2221 is provided on one side of the transverse support column 222 to limit the moving range of the transverse support column 222. The limiting protrusion 2221 and the positioning member 223 are respectively provided on two opposite sides of the transverse support column 222 along the vertical support column 211. The limiting protrusion 2221 can stop the transverse support column 222 at a predetermined position, and the positioning member 223 can be accurately located above the end of the spring, so that the positioning groove is aligned with the end of the spring.
[0043] In an embodiment of the utility model, the positioning member 223 includes a positioning rod 2231, a limit block 2232 and a first elastic member 2233. The positioning rod 2231 is movably arranged on the transverse support column 222 along the radial direction of the transverse support column 222, and the positioning head 221 is provided at the end of the positioning rod 2231 away from the transverse support column 222; the limit block 2232 and the first elastic member 2233 are both sleeved on the outside of the positioning rod 2231 and are relatively arranged along the transverse support column 222, and the two ends of the first elastic member 2233 are respectively abutted against the positioning head 221 and the transverse support column 222.
[0044] In detail, Figure 1The positioning member 223 is configured as a positioning rod 2231, a stopper 2232, and a second elastic member 2233. The positioning rod 2231 can move vertically, and a positioning head 221 is provided on the positioning rod 2231 so as to abut against the clamping mechanism 10. The stopper 2232 can accurately stop the positioning rod 2231 at a predetermined position, and the accuracy of the vertical movement of the positioning rod 2231 can be ensured, so that the positioning rod 2231 accurately abuts against the clamping mechanism 10, and the positioning groove is aligned with the end of the spring. The second elastic member 2233 can help the positioning rod 2231 to automatically rebound to a position abutting against the clamping mechanism 10 after being lifted, so as to facilitate use.
[0045] In the embodiment of the present invention, the positioning groove is extended along the length direction of the positioning rod 2231 .
[0046] It is worth noting that the positioning groove is extended along the length direction of the positioning rod 2231, that is, the positioning groove is opened vertically to facilitate alignment with the spring end. The positioning head 221 of the positioning rod 2231 is supported on the clamping mechanism 10, which can accurately control the extension distance of the spring end.
[0047] The depth of the positioning groove can be set according to actual needs. In this embodiment, it is set to 0.01-0.02 mm. Medical springs are especially used in precision medical equipment, such as intravascular microcatheter springs, and the size is very small and precise, and is set to 0.01-0.02 mm for easy use.
[0048] In an embodiment of the utility model, the clamping mechanism 10 includes two clamping blocks 11, which are movably arranged to achieve relative proximity or relative distance, and half grooves 111 are provided on the opposite surfaces of the two clamping blocks 11, and the two half grooves 111 form the clamping groove.
[0049] Specifically, by providing the clamping mechanism 10 with two movable clamping blocks 11, the two clamping blocks 11 can move in coordination, and by adjusting the positions of the two clamping blocks 11, it is convenient to clamp the spring, and the clamping force can be more evenly distributed through adjustment.
[0050] When the extension height of the spring needs to be controlled by the positioning mechanism 20, the positions of the two clamping blocks 11 can be adjusted so that the spring can move only under the action of an external force. When laser melting is required, the spring can be kept in a state where it can move only under the action of an external force, or the positions of the two clamping blocks 11 can be adjusted again to clamp the spring, thereby reducing the displacement or vibration of the spring during the processing, such as accidentally hitting the fixture, etc., thereby improving the processing accuracy and surface quality.
[0051] In an embodiment of the utility model, the clamping mechanism 10 also includes two support blocks 12, and the two support blocks 12 can be movably arranged to achieve relative proximity or relative distance, and the fixing member 21 is arranged on the support block 12; the opposite surfaces of the two support blocks 12 are provided with installation grooves (not marked in the figure), and the clamping block 11 is installed in the installation groove.
[0052] In detail, Figure 5 By setting the two support blocks 12 to drive the two clamping blocks 11 to be relatively close or far away, the clamping is more stable, which makes it convenient to connect the fixing member 21 to the support block 12. At the same time, it is convenient to set other components such as the guide rod 13, the second elastic member 14, etc. on the support block 12 to further realize other functions.
[0053] In an embodiment of the utility model, the support block 12 is provided with a half hole 121 from the top toward the bottom, and the two half holes 121 form a receiving hole (not marked in the figure); the clamping block 11 partially extends out of the installation groove and is located in the receiving hole, and the positioning head 221 extends into the receiving hole and abuts against the top surface of the clamping block 11 to align the positioning groove with the end of the spring.
[0054] It is worth noting that Figure 1 and Figure 5 A receiving hole is also provided on the two support blocks 12 for receiving the positioning head 221. The shape of the positioning head 221 is adapted to the shape of the receiving hole. After the positioning head 221 is inserted into the receiving hole, the positioning groove of the positioning head 221 can be more accurately aligned with the end of the spring, which is convenient for use.
[0055] In an embodiment of the utility model, the clamping mechanism 10 also includes a guide rod 13, one end of which is fixed to one of the support blocks 12, and the other support block 12 moves along the guide rod 13 to be relatively close to or relatively far away from one of the support blocks 12; and / or, the clamping mechanism 10 also includes a second elastic member 14, which is connected between the two support blocks 12 for resetting the two support blocks 12 after they are relatively far away from each other.
[0056] In detail, Figure 4 and Figure 5 Two guide rods 13 are arranged between the two support blocks 12. One of the two support blocks 12 can move relative to the other support block 12. The movement of one of the support blocks 12 can be guided by the two guide rods 13, so that the two clamping blocks 11 can be accurately docked to clamp the spring; and the guide rods 13 can provide support, reduce shaking and deviation, and increase the stability and reliability of the spring melting head fixture 100.
[0057] A second elastic member 14 is also provided, and the second elastic member 14 can be a spring or an elastic airbag. Figure 4 Two springs are arranged on both sides of the two support blocks 12, and the springs can allow the support blocks 12 to accurately return to the predetermined positions and keep the two support blocks 12 in a relatively close relationship.
[0058] The utility model further provides a laser processing device (not shown in the figure) for processing springs, comprising a laser mechanism (not shown in the figure) and the spring melting head fixture 100 as described above.
[0059] Specifically, the laser processing equipment includes a laser mechanism and a spring melting head jig 100. The spring melting head jig 100 is arranged upstream of the laser mechanism. When the spring melting head jig 100 clamps the spring and makes the spring end extend a preset distance, the positioning component 22 moves away from the clamping groove, and the laser mechanism is used to process the melting head of the spring end so that the spring end forms a hemispherical structure with high precision.

Since the laser processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
