Referring to fig. 1 to 6, the present embodiment provides a fixing jig for fixing a core 10, the fixing jig including a fixing block 100 and a movable die set 200.

Specifically, the fixing block 100 includes a fixing surface 110, and a plurality of fixing grooves 111 are formed in the fixing surface 110 along a first direction, and the fixing grooves 111 are used for placing the cores 10 extending along a second direction.

Specifically, the movable module 200 includes a movable block 210, a plurality of positioning members 220 slidably connected to the movable block 210, and a first elastic member 230 connected to the positioning members 220, where each of the fixing grooves 111 is disposed corresponding to at least one of the positioning members 220, the movable block 210 is configured to drive the positioning members 220 to move toward the fixed block 100 along a third direction to press against the core 10 in the fixing groove 111, and the first elastic member 230 is configured to provide a force for moving the positioning members 220 toward the fixed block 100. Specifically, the first elastic member 230 may include, but is not limited to, a spring. In fig. 1, the a direction is the first direction, the b direction is the second direction, and the c direction is the third direction.

In this embodiment, before the core 10 is machined, the core 10 is first placed in the fixing groove 111 of the fixing block 100, and then the movable block 210 is moved toward the fixing block 100 along the third direction, so that the positioning piece 220 is pressed against the core 10, thereby realizing the fixation of the core 10, having convenient operation, time saving and labor saving, realizing the purpose of clamping multiple cores 10 simultaneously, realizing batch machining, effectively improving the fixation efficiency of the core 10, and improving the production efficiency of the core 10. In addition, the design of the first elastic piece 230 provides buffering for clamping the core 10, so that the situation that the positioning piece 220 excessively presses the core 10 to damage the surface of the core 10 is effectively avoided, the first elastic piece 230 corresponds to the positioning piece 220 one by one, and each core 10 is effectively ensured to be clamped and fixed stably. The fixing clamp is suitable for clamping and fixing the core 10 with the outer diameter of 1mm-8mm, and the core 10 with the diameter of 1mm can be clamped in the fixing groove 111 on the same fixing surface 110. Of course, by changing the size of the fixing groove 111 on the fixing member, the fixing jig can be adapted to clamp and fix cores 10 of other diameters.

In a possible embodiment, as shown in fig. 1, the fixing surfaces 110 are disposed on two sides of the fixing block 100 along the third direction, the fixing fixture is provided with two movable modules 200, the movable modules 200 are in one-to-one correspondence with the fixing surfaces 110, and a plurality of fixing slots 111 are respectively formed on each fixing surface 110 along the first direction, so that the fixing fixture can simultaneously clamp and fix more cores 10. For example, 3-16 fixing grooves 111 may be formed on each fixing surface 110, and of course, other numbers of fixing grooves 111 may be formed on the fixing surface 110, which is not limited in particular. Preferably, 5, 6, 8, 10 or 12 fixing grooves 111 are formed on the fixing surface 110.

In one possible embodiment, as shown in FIG. 3, the retaining groove 111 may be an open groove to facilitate placement of the mandrel 10. Further, the width B of the fixing groove 111 may be gradually reduced from the opening to the groove bottom along the third direction, so that the fixing groove 111 is suitable for clamping and fixing the cores 10 with various specifications, and the application range is wide. For example, the fixing groove 111 has a V-shape, and the two inner surfaces of the fixing groove 111 and the positioning member 220 perform three-point positioning, so that the stability of clamping and fixing the core 10 is effectively ensured.

In a possible embodiment, the width B1 of one end of the positioning member 220, which is used to press against the core 10 in the fixing groove 111, is smaller than the opening width B2 of the fixing groove 111, and it can be understood that the positioning member 220 can extend into the fixing groove 111, so that the fixing clamp can clamp the core 10 with a smaller outer diameter, which has a wide application range. In this embodiment, the opening width B2 of the fixing groove 111 may refer to a partial width of the fixing groove 111 corresponding to the positioning member 220 along the third direction, which is understood to be that a groove enough for the positioning member 220 to extend into is formed on the inner surface of the fixing groove 111.

In one possible embodiment, as shown in fig. 4 and 5, the positioning member 220 includes a first positioning member 221 and a second positioning member 222. Specifically, the first positioning pieces 221 are disposed in one-to-one correspondence with the fixing grooves 111, one end of each first positioning piece 221 is provided with a first positioning plate 2211, the first positioning plates 2211 are used for pressing the core 10 in the fixing groove 111, and the width of each first positioning plate 2211 is extended along the second direction so as to fix the core 10 in the second direction; the second positioning pieces 222 are arranged in one-to-one correspondence with the fixing grooves 111, the first positioning pieces 221 and the second positioning pieces 222 are arranged at intervals along the second direction, one end of each second positioning piece 222 is provided with a second positioning plate 2221, the second positioning plates 2221 are used for propping against the mold cores 10 in the fixing grooves 111, and the width of each second positioning plate 2221 is arranged in an extending mode along the first direction so as to fix the mold cores 10 in the first direction. In the present embodiment, when the core 10 is offset with respect to the center of the fixing groove 111, by the arrangement of the second positioning plate 2221, it is possible to effectively prevent the occurrence of the situation in which the first positioning plate 2211 eccentrically abuts against the core 10 and the core 10 is pressed to the side of the first positioning plate 2211, and it is more convenient to clamp and fix the core 10.

In one possible embodiment, as shown in fig. 6, an end of the positioning member 220 connected to the first elastic member 230 is in a stepped shaft shape and has a stepped surface 2201, and the first elastic member 230 is sleeved on the positioning member 220 and abuts against the stepped surface 2201. Further, the surface of the step 11 of the core 10 facing the positioning member 220 is a plane, and the plane is on the same plane as the tangential surface of the processing end facing the positioning member 220. In general, when the core 10 is clamped and fixed by the fixing jig, the first positioning plate 2211 abuts on a plane of a side of the stepped portion 11 of the core 10 facing the positioning piece 220.

In one possible embodiment, as shown in fig. 6, when the first elastic member 230 is in the natural state, the distance H1 between the first positioning plate 2211 and the fixing groove 111 is smaller than or equal to the distance H2 between the second positioning plate 2221 and the fixing groove 111, and it is understood that when both the first positioning plate 2211 and the second positioning plate 2221 are separated from the core 10, the distance H1 between the first positioning plate 2211 and the fixing groove 111 is smaller than or equal to the distance H2 between the second positioning plate 2221 and the fixing groove 111. In the present embodiment, when the movable block 210 moves toward the fixed block 100, the second positioning plate 2221 contacts the core 10 first, so as to more effectively avoid the situation that the first positioning plate 2211 eccentrically contacts the core 10 and presses the core 10 to one side of the first positioning plate 2211.

In one possible embodiment, as shown in fig. 4 and 5, the first elastic member 230 is provided with a plurality of corresponding connection with the positioning members 220. In a possible embodiment, the positioning members 220 corresponding to each fixing groove 111 may be connected to the same first elastic member 230, or all the positioning members 220 may be connected to the same first elastic member 230. Of course, the corresponding relationship between the first elastic member 230 and the positioning member 220 may be other forms, which is not limited in the present utility model.

For example, an end of the first positioning member 221 facing away from the first positioning plate 2211 and an end of the second positioning member 222 facing away from the second positioning plate 2221 are respectively abutted against the corresponding first elastic member 230. For example, the elastic coefficient of the first elastic member 230 connected to the first positioning plate 2211 may be greater than or equal to the elastic coefficient of the first elastic member 230 connected to the second positioning plate 2221, and since the contact line length of the first positioning plate 2211 and the core 10 is greater than the contact line length between the second positioning plate 2221 and the core 10 in the second direction, the core 10 can be more stably clamped and fixed by the first positioning plate 2211.

In one possible embodiment, as shown in fig. 7, the end of the second positioning plate 2221 is provided with an inner groove 2202, and the inner surface of the inner groove 2202 is used to press the core 10 in the fixing groove 111. Wherein the inner groove 2202 may be an arcuate groove. In this embodiment, after the core 10 is placed at the fixing groove 111, there may not be a gap between the core 10 and the inner surface of the fixing groove 111, i.e., the core 10 may not be centered with the fixing groove 111 in the third direction, and during the movement of the movable block 210 toward the fixed block 100 in the third direction, the inner groove 2202 has a guiding effect on the movement of the core toward the fixing groove 111, i.e., the inner surface of the inner groove 2202 pushes against the core 10 toward the center of the fixing groove 111, so that scratches caused by excessive extrusion of the core 10 by one of the second positioning plate 2221 and the two inner surfaces of the fixing groove 111 are effectively avoided.
