Description

Technical Field

[0001] The utility model relates to a welding fixture, in particular to a guide wire welding fixture. Background Art

[0002] The guide wire has a welding process during production. The guide wire welding needs to place the guide wire between two molds, and force is applied to the two molds to open and close them, so as to clamp the guide wire in place. When guide wires of different specifications need to be welded, the mold needs to be removed from the equipment, and the disassembly and assembly of the mold and the equipment is relatively troublesome, especially the disassembly and assembly of the mold and the drive structure on the equipment. After the assembly is completed, it is also necessary to check whether the drive of the mold is in place to ensure the clamping of the guide wire. Therefore, the current efficiency of clamping different guide wires is low, and it is difficult to improve the overall processing efficiency. Utility Model Content

[0003] The utility model aims to provide a wire welding fixture to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] The wire welding fixture comprises: a fixed seat, one side of which is provided with a fixed die; a movable seat, which can move in a direction close to or away from the fixed seat, a movable die is provided on the side of the movable seat opposite to the fixed die, a first clamping groove extending in the up-down direction is provided on the side of the fixed die opposite to the movable die, a second clamping groove extending in the up-down direction is provided at the position of the movable die opposite to the first clamping groove, the fixed die is detachably connected to the fixed seat, and the movable die is detachably connected to the movable seat.

[0006] This technical solution has at least the following beneficial effects: the fixed seat is used to be installed on the fixed structure of the peripheral device, and the movable seat is used to be installed on the driving structure of the peripheral device or a structure without a driving source. The fixed mold on the fixed seat and the movable mold of the movable seat are opposite to each other. When in use, the guide wire is first placed in the first clamping groove of the fixed mold, and the movable seat is moved close to the fixed seat by the driving structure of the peripheral device or manually, so that the first clamping groove and the second clamping groove are closed together to clamp the guide wire. When it is necessary to clamp guide wires of different specifications, the fixed mold in the fixed seat and the movable mold in the movable seat are directly removed and replaced without changing the connection state of the fixed seat and the movable seat. In this way, it can quickly adapt to clamping guide wires of different specifications, improve the flexibility and convenience of operation, and thus help improve the overall processing efficiency.

[0007] As a further improvement of the above technical solution, a first installation groove is provided on the side of the fixed seat facing the movable mold, the fixed mold is inserted into the first installation groove, a first avoidance hole is provided on the top side of the fixed seat facing the first clamping groove, and a first guide groove is provided on the bottom side of the fixed seat facing the first clamping groove. A first installation groove for installing and positioning the fixed seat is provided in the fixed mold, and the fixed mold can be installed in the fixed seat to reduce the exposure of the mold. When in use, the guide wire is passed through the first guide groove on the bottom side of the fixed seat into the first clamping groove, and a first avoidance hole for avoiding an external welding gun is provided on the top side of the fixed seat. During processing, the welding gun can perform welding processing on the top of the guide wire from the first avoidance hole.

[0008] As a further improvement of the above technical solution, the movable seat is provided with a second mounting groove on the side facing the fixed die, the movable die is inserted into the second mounting groove, the top side of the movable seat is provided with a second avoidance hole at the position facing the second clamping groove, and the bottom side of the movable seat is provided with a second guide groove at the position facing the second clamping groove. A second mounting groove for installing and positioning the movable seat is provided in the movable die. When in use, the guide wire can also be inserted into the second clamping groove from the second guide groove at the bottom side of the movable seat. When the movable die and the fixed die are close to each other, the guide wire is clamped between the first clamping groove and the second clamping groove. A second avoidance hole for avoiding the external welding gun is also provided on the top side of the movable seat. During processing, the top end of the guide wire only needs to extend from between the first clamping groove and the second clamping groove to the first avoidance hole and the second avoidance hole. The first avoidance hole and the second avoidance hole can also form a space for limiting the position of the welding gun. When the welding gun approaches, it enters the space, more accurately limiting the processing position of the welding gun and improving the welding processing quality of the guide wire.

[0009] As a further improvement of the above technical solution, the top side of the movable seat is sequentially formed with an avoidance section and a shielding section in the direction close to the fixed seat, and the second avoidance hole is formed in the avoidance section. The movable seat can move away from the fixed seat and make the shielding section shield the first clamping groove. When the movable seat is away from the fixed seat, the shielding section shields the first clamping groove. At this time, the guide wire is inserted upward into the first clamping groove, and the travel of the guide wire is limited by the blocking of the shielding section. In this way, the guide wire can be placed in place, which is conducive to improving the quality of the guide wire welding process. When the movable seat is close to the fixed seat, the shielding section is staggered with the first clamping groove. At this time, the second avoidance hole on the avoidance section is opposite to the first clamping groove, exposing the guide wire, and the external welding gun can perform welding processing on the guide wire through the second avoidance hole.

[0010] As a further improvement of the above technical solution, when the movable seat is close to the fixed seat, the shielding section is inserted into the first avoidance hole. When the movable seat is close to the fixed seat, the shielding section enters the first avoidance hole opened on the top side of the fixed seat, and the mutual cooperation between the two can further position the movable seat and the fixed seat, improve the accuracy of the movement of the movable seat, and better clamp and fix the guide wire.

[0011] As a further improvement of the above technical solution, a positioning groove is provided on the bottom side of the shielding section, and the positioning groove extends to the second avoidance hole. When the guide wire moves up to the position and is blocked by the shielding section, the top end of the guide wire extends into the second avoidance hole, and the second avoidance hole is used to stabilize the top end position of the guide wire. When the movable seat approaches the fixed seat, the top end of the guide wire is not easy to shake and deviate due to the friction of the shielding section, which is conducive to ensuring the welding gun to process it.

[0012] As a further improvement of the above technical solution, the first guide groove includes a first limit section and a first guide section arranged in sequence from top to bottom, and the space of the first guide section gradually decreases from bottom to top. When the guide wire is passed upward into the first clamping groove, the space of the first guide section gradually decreases upward to guide the movement of the guide wire, so that the guide wire accurately enters the first limit section, and then enters the first clamping groove from the first limit section, thereby improving the efficiency of positioning the guide wire during feeding.

[0013] As a further improvement of the above technical solution, the second guide groove includes a second limit segment and a second guide segment arranged in sequence from top to bottom, and the space of the second guide segment gradually decreases from bottom to top. Similarly, when the guide wire is passed upward into the second clamping groove, the space of the second guide segment gradually decreases upward can guide the movement of the guide wire, so that the guide wire accurately enters the second limit segment, and then enters the second clamping groove from the second limit segment, thereby improving the efficiency of positioning the guide wire during feeding.

[0014] As a further improvement of the above technical solution, a guide column is connected to the fixed seat, and a receiving groove is arranged at the position of the movable seat opposite to the guide column. The guide column passes through the fixed seat from the bottom of the receiving groove, and a spring is sleeved on the outer side of the guide column, and the spring is located in the receiving groove. The movable seat cooperates with the guide column to improve the stability of the movement relative to the fixed seat to move closer or farther away. When the movable seat approaches the fixed seat, the spring located in the receiving groove is compressed and deformed under the extrusion of the fixed seat and the bottom of the receiving groove. When the pressure on the movable seat is removed, the spring elastically recovers, and the elastic force provided by the spring can push the movable seat away from the fixed seat, thereby realizing the resetting of the movable seat. This can improve the convenience of controlling the activity of the movable mold, and the structure is simpler and more practical.

[0015] As a further improvement of the above technical solution, the fixed mold and the movable mold are both made of copper. The guide wire moves more smoothly on the copper fixed mold and the movable mold, which reduces the wear on the guide wire and improves the processing quality of the guide wire.

[0025] Reference Figure 1 and Figure 2 The guide wire welding fixture comprises a fixed seat 100 and a movable seat 200, wherein a fixed die is arranged on one side of the fixed seat 100; the movable seat 200 can move in a direction close to or away from the fixed seat 100, a movable die is arranged on a side of the movable seat 200 facing the fixed die, a first clamping groove extending in the up-down direction is arranged on a side of the fixed die facing the movable die, and a second clamping groove extending in the up-down direction is arranged at a position of the movable die facing the first clamping groove, the fixed die is detachably connected to the fixed seat 100, and the movable die is detachably connected to the movable seat 200. In practical applications, the movable seat 200 can be driven manually, or the movable seat 200 can be installed on a driving structure of an external device and driven by the driving structure of the external device.

[0026] As can be seen from the above, the fixed seat 100 is used to be installed on the fixed structure of the peripheral device, and the movable seat 200 is used to be installed on the driving structure of the peripheral device or a structure without a driving source. The fixed mold on the fixed seat 100 and the movable mold of the movable seat 200 are opposite to each other. When in use, the guide wire is first placed in the first clamping groove of the fixed mold, and the movable seat 200 is moved close to the fixed seat 100 by the driving structure of the peripheral device or manually, so that the first clamping groove and the second clamping groove are closed together to clamp the guide wire. When it is necessary to clamp guide wires of different specifications, the fixed mold in the fixed seat 100 and the movable mold in the movable seat 200 are directly removed and replaced without changing the connection state of the fixed seat 100 and the movable seat 200. In this way, it can quickly adapt to the clamping of guide wires of different specifications, improve the flexibility and convenience of operation, and thus help to improve the overall processing efficiency.

[0027] The fixed mold can be directly installed on the side wall of the fixed seat 100, and in the present embodiment, the fixed mold is installed in the fixed seat 100. Specifically, a first installation groove is provided on the side of the fixed seat 100 facing the movable mold, and the fixed mold is inserted into the first installation groove. A first avoidance hole 110 is provided on the top side of the fixed seat 100 facing the first clamping groove, and a first guide groove is provided on the bottom side of the fixed seat 100 facing the first clamping groove. A first installation groove for installing and positioning the fixed seat 100 is provided in the fixed mold. The fixed mold can be installed in the fixed seat 100 to reduce the exposure of the mold. When in use, the guide wire is inserted into the first clamping groove from the first guide groove on the bottom side of the fixed seat 100. A first avoidance hole 110 for avoiding an external welding gun is provided on the top side of the fixed seat 100. During processing, the welding gun can perform welding processing on the top of the guide wire from the first avoidance hole 110. In actual applications, the side surfaces of the fixed mold and the fixed base 100 are coplanar, and the side surfaces of the movable mold and the movable base 200 are coplanar. When the side surfaces of the movable mold are pressed against the side surfaces of the fixed mold, the side surfaces of the movable base 200 are also pressed against the side surfaces of the fixed base 100, which can disperse the impact force during mold closing and improve the overall service life.

[0028] Similarly, the movable mold can also be directly mounted on the side wall of the movable seat 200. In this embodiment, Figure 3 As shown, a second mounting groove 210 is provided on the side of the movable seat 200 facing the fixed mold, the movable mold is inserted into the second mounting groove 210, a second avoidance hole 223 is provided on the top side of the movable seat 200 facing the second clamping groove, and a second guide groove is provided on the bottom side of the movable seat 200 facing the second clamping groove. A second installation groove 210 for installing and positioning the movable seat 200 is provided in the movable mold. When in use, the guide wire can also be inserted into the second clamping groove from the second guide groove on the bottom side of the movable seat 200. When the movable mold and the fixed mold are close to each other, the guide wire is clamped between the first clamping groove and the second clamping groove. A second avoidance hole 223 for avoiding the external welding gun is also provided on the top side of the movable seat 200. During processing, the top end of the guide wire only needs to extend from between the first clamping groove and the second clamping groove to the first avoidance hole 110 and the second avoidance hole 223. The first avoidance hole 110 and the second avoidance hole 223 can also form a space for limiting the welding gun. When the welding gun approaches, it enters the space, which more accurately defines the processing position of the welding gun and improves the welding processing quality of the guide wire.

[0029] When the fixed mold is installed into the fixed seat 100, the fixed mold can be positioned in the fixed seat 100 only by relying on the interference fit between the fixed mold and the fixed seat 100. In order to further improve the stability of the installation of the fixed mold, screws can be driven into the bottom side of the fixed seat 100, and the end of the screw can be pressed against the bottom side of the fixed mold to further press and position the fixed mold. Similarly, for the installation of the movable mold, screws can be driven into the bottom side of the movable seat 200, and the end of the screw can be pressed against the bottom side of the movable mold to press and position the movable mold in the movable seat 200.

[0030] When the first avoidance hole 110 is formed on the top side of the fixed seat 100 and the first clamping groove is directly exposed, and the second avoidance hole 223 is formed on the top side of the movable seat 200 and the second clamping groove is directly exposed, the guide wire is fed between the first clamping groove and the second clamping groove. At this time, it is difficult to accurately grasp the height of the guide wire extending into the first avoidance hole 110 and the second avoidance hole 223. In order to improve the accuracy and efficiency of guide wire feeding, in this embodiment, the top side of the movable seat 200 is sequentially formed with an avoidance section 221 and a shielding section 222 in the direction close to the fixed seat 100, and the second avoidance hole 223 is formed in the avoidance section 221, and the movable seat 200 can move away from the fixed seat 100 and make the shielding section 222 shield the first clamping groove. When the movable seat 200 is away from the fixed seat 100, the shielding section 222 blocks the first clamping groove. At this time, the guide wire is inserted upward into the first clamping groove, and the blocking section 222 is used to limit the travel of the guide wire. This can ensure that the guide wire is placed in place, which is beneficial to improving the quality of the guide wire welding process. When the movable seat 200 is close to the fixed seat 100, the shielding section 222 is offset from the first clamping groove. At this time, the second avoidance hole 223 on the avoidance section 221 is opposite to the first clamping groove, exposing the guide wire, and the external welding gun can weld the guide wire through the second avoidance hole 223.

[0031] In the above embodiment, when the shielding section 222 shields the first clamping groove, it can be located directly above the first avoidance hole 110. In the present embodiment, when the movable seat 200 is close to the fixed seat 100, the shielding section 222 is inserted into the first avoidance hole 110. When the movable seat 200 is close to the fixed seat 100, the shielding section 222 enters the first avoidance hole 110 opened on the top side of the fixed seat 100. The mutual cooperation between the two can further position the movable seat 200 and the fixed seat 100, improve the accuracy of the movement of the movable seat 200, and better clamp and fix the guide wire.

[0032] In order to further improve the limiting effect of the guide wire, in this embodiment, a positioning groove 224 is provided on the bottom side of the shielding section 222, and the positioning groove 224 extends to the second avoidance hole 223. When the guide wire moves up to the position and is blocked by the shielding section 222, the top end of the guide wire extends into the second avoidance hole 223, and the second avoidance hole 223 is used to stabilize the top end position of the guide wire. When the movable seat 200 approaches the fixed seat 100, the top end of the guide wire is not easy to shake and deviate due to the friction of the shielding section 222, which is conducive to ensuring the welding process of the welding gun.

[0033] When the guide wire is passed from the first guide groove to the first clamping groove from bottom to top, since the shape of the first clamping groove matches the shape of the guide wire, it is difficult to directly position the guide wire in the first clamping groove in this state. Therefore, a guiding structure for the first guide wire can be provided in the first guide groove. Specifically, the first guide groove includes a first limiting segment and a first guiding segment arranged in sequence from top to bottom, and the space of the first guiding segment gradually decreases from bottom to top. When the guide wire is passed upward into the first clamping groove, the space of the first guiding segment gradually decreases upward to guide the movement of the guide wire, so that the guide wire accurately enters the first limiting segment, and then enters the first clamping groove from the first limiting segment, thereby improving the efficiency of positioning the guide wire during feeding.

[0034] Similarly, the second guide groove includes a second limit segment 231 and a second guide segment 232 arranged in sequence from top to bottom, and the space of the second guide segment 232 gradually decreases from bottom to top. When the guide wire is passed upward into the second clamping groove, the gradually decreasing space of the second guide segment 232 can guide the movement of the guide wire, so that the guide wire accurately enters the second limit segment 231, and then enters the second clamping groove from the second limit segment 231, thereby improving the efficiency of positioning the guide wire during feeding.

[0035] In practical applications, the shape formed by the first limiting segment and the second limiting segment 231 can be a tapered space that gradually shrinks from bottom to top, which can better guide the guide wire.

[0036] In the above embodiment, the movable seat 200 and the fixed seat 100 can be installed on different structural parts respectively, and the movable seat 200 is driven to move closer to or away from the fixed seat 100 by external force. In order to improve the stability of the relative movement between the movable seat 200 and the fixed seat 100, in this embodiment, a guide column 120 is connected to the fixed seat 100, and a receiving groove 240 is provided at a position of the movable seat 200 opposite to the guide column 120. The guide column 120 passes through the fixed seat 100 from the bottom of the receiving groove 240, and a spring is provided on the outer side of the guide column 120, and the spring is located in the receiving groove 240. The movable seat 200 cooperates with the guide column 120 to improve the stability of the relative movement towards or away from the fixed seat 100. When the movable seat 200 approaches the fixed seat 100, the spring located in the receiving groove 240 is compressed and deformed under the extrusion of the fixed seat 100 and the bottom of the receiving groove 240. When the pressure on the movable seat 200 is removed, the spring elastically recovers, and the elastic force provided by the spring can push the movable seat 200 away from the fixed seat 100, thereby realizing the resetting of the movable seat 200. This can improve the convenience of controlling the activity of the movable mold, and the structure is simpler and more practical.

[0037] In actual application, the distance between the movable seat 200 and the fixed seat 100 will not be too large when they are far away from each other. Only the space between the first clamping groove and the second clamping groove is slightly opened to facilitate the loading and unloading of the guide wire. In order to improve the stability of the relative activity between the two, there are two guide pillars 120. Similarly, there are two springs. The two springs are respectively mounted on the outside of the two guide pillars 120 to improve the stability of the force applied when the movable seat 200 is reset.

[0038] In some embodiments, the fixed mold and the movable mold are both made of copper. The guide wire moves more smoothly on the fixed mold and the movable mold made of copper, which reduces wear on the guide wire and improves the processing quality of the guide wire.

[0039] There are various driving structures for driving the movable seat 200 to move. For example, the movable seat 200 can be directly installed on a driving source such as a cylinder or an electric screw to be driven by the driving source such as the cylinder or the electric screw, or a manually pressed handle can be installed to drive the movable seat 200 to move by pressing the lever.

[0040] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
