Description

Technical Field

[0001] This invention relates to the field of relay manufacturing technology, and in particular to a relay conformal welding device. Background Technology

[0002] In relay production, a welding device is used to laser weld the relay product housing to the stationary components. This welding device mainly consists of a welding head and a fixing fixture. The fixing fixture is used to fix the product housing and stationary components and make them rotate around a fixed axis, while the welding head does not move.

[0003] This welding device is only suitable for welding contours that are perfectly circular. For products with irregular shapes such as waist-shaped or rectangular contours where the outer shell and stationary components are welded, the distance between the welding point and the welding head changes continuously as the product rotates if this welding device is used. In laser welding, the focal length (i.e., the distance between the welding head and the welding point) has a significant impact on the width and depth of the weld. Therefore, existing welding devices cannot meet the production requirements for products with irregular weld contours. Summary of the Invention

[0004] The purpose of this invention is to provide a relay contour welding device to solve the problem that the relative position between the welding head and the product changes significantly when welding irregularly shaped products such as waist-shaped or rectangular products, thereby affecting the welding quality.

[0005] Specifically, the technical solution of the present invention is:

[0006] A relay contour welding device includes a welding head and a fixing fixture. The fixing fixture includes a bracket, a fixing rod, and a rotary drive mechanism, an active seat, and a driven seat arranged sequentially along a first direction. The rotary drive mechanism and the driven seat are respectively connected to the bracket, and both the rotary drive mechanism and the driven seat can move relative to the bracket perpendicular to the first direction. The fixing rod is fixedly connected to the bracket. The output end of the rotary drive mechanism is fixedly connected to the active seat. The active seat is provided with a contour track corresponding to the welding contour of the relay.

The driven seat is connected to the fixed frame and can move perpendicular to the first direction relative to the fixed frame. The adjusting member is connected to the fixed frame and is used to move the movable plate parallel to the first direction relative to the fixed frame, so that the active seat moves closer to or away from the relay product.

[0013] Preferably, the adjusting member is threadedly connected to the fixed frame, thereby allowing it to move parallel to the fixed frame in a first direction.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The relay contour welding device provided by this invention can be used to weld relay product housings and stationary components, and can also be extended to other similar scenarios. Although designed for welding products with irregular contours, it is also suitable for welding products with perfectly circular contours.

[0024] The relay contour welding device includes a welding head and a fixing fixture. The structure of the welding head is not an improvement of this invention. It can be selected from existing welding heads as needed, such as commonly used laser welding heads.

[0025] Figures 1 to 4 The drawing shows the fixture included in one embodiment of the present invention, with the welding head included in this embodiment omitted.

[0026] like Figure 1 As shown, in this embodiment, the fixed fixture includes a bracket, a fixed rod 1, and a rotary drive mechanism 2, an active seat 3, and a driven seat 4 arranged sequentially along the first direction i. The rotary drive mechanism 2 and the driven seat 4 are respectively connected to the bracket, and both the rotary drive mechanism 2 and the driven seat 4 can move relative to the bracket perpendicular to the first direction i. The fixed rod 1 is fixedly connected to the bracket. The output end 21 of the rotary drive mechanism 2 is fixedly connected to the active seat 3. The active seat 3 is provided with a contoured track 31 corresponding to the welding contour of the relay. The fixed rod 1 is inserted in the contoured track 31 to guide the movement of the active seat 3 relative to the fixed rod 1.

[0027] from Figure 4 The installation position of the welding object—relay product 100—on this fixed fixture can be seen. The contour track 31 should be designed according to the welding profile of product 100 to ensure that the distance between the welding head and the welding point remains stable during welding.

[0028] The relay conformal welding device also includes a first sliding assembly and a second sliding assembly; the rotary drive mechanism 2 is connected to the bracket via the first sliding assembly, thereby moving relative to the bracket perpendicular to the first direction i under the guidance of the first sliding assembly; the driven seat 4 is connected to the bracket via the second sliding assembly, thereby moving relative to the bracket perpendicular to the first direction i under the guidance of the second sliding assembly; the driven seat 4 is rotatably connected to the second sliding assembly, thereby rotating together with the driving seat 3, the product 100, and the driven seat 4 under the drive of the rotary drive mechanism 2. Both the first and second sliding assemblies include a mechanism for achieving lateral ( Figure 4 A lateral guide mechanism for sliding in the X direction (as shown) and a mechanism for achieving longitudinal ( Figure 4 The longitudinal guide mechanism (shown in the Y direction) slides, and the lateral guide mechanism and the longitudinal guide mechanism work together. The fixed rod 1 and the contour track 31 limit the motion trajectory, realizing the contour movement of the product 100, with good fault tolerance.

[0029] Preferably, such as Figures 2 to 4 As shown, the first sliding assembly includes a first slider a1, a first slide rail a2, a first plate a3, a second slider a4, a second slide rail a5, and a second plate a6 arranged sequentially along the first direction i. The first slider a1 is fixed on the bracket; the first slide rail a2 is fixed on the first plate a3 and slidably connected to the first slider a1; the second slider a4 is fixed on the first plate a3; the second slide rail a5 is fixed on the second plate a6 and slidably connected to the second slider a4; the rotary drive mechanism 2 is fixed on the second plate a6; the first slide rail a2 is perpendicular to the second slide rail a5.

[0030] The second sliding assembly includes a third plate b1, a third slide rail b2, a third slider b3, a fourth plate b4, a fourth slide rail b5, and a fourth slider b6 arranged sequentially along the first direction i. The driven seat 4 is rotatably connected to the third plate b1. The third slide rail b2 is fixed on the third plate b1 and slidably connected to the third slider b3. The third slider b3 is fixed on the fourth plate b4. The fourth slide rail b5 is fixed on the fourth plate b4 and slidably connected to the fourth slider b6. The fourth slider b6 is fixed on the bracket. The third slide rail b2 and the fourth slide rail b5 are perpendicular.

[0031] In other embodiments, the first and / or second sliding components may be omitted, and other connection structures may be used instead to achieve the floating of the rotary drive mechanism 2, the active seat 3, the product 100 and the driven seat 4 relative to the base in a direction perpendicular to the first direction i. For example, contour tracks may be set on the bracket corresponding to the rotary drive mechanism 2 and the driven seat 4 respectively.

[0032] In this embodiment, as Figure 3 , 4 As shown, the driven seat 4 includes a driven seat body and a connecting member 41. The connecting member 41 is fixed to the driven seat body and is rotatably connected to the third plate b1. The driven seat body and the connecting member 41 are made of different materials. The driven seat body is made of aluminum alloy to reduce weight.

[0033] In this embodiment, as Figure 3 As shown, the driven seat body is provided with a mounting groove 42 and a fixing member (not shown). The fixing member is connected to the mounting groove 42 to fix the product 100 in the mounting groove 42 to prevent the product 100 from falling out. Figure 3 The hole for the fixing part can be seen on the driven seat body.

[0034] In this embodiment, the bracket includes a fixed frame 5, a movable plate 6, and an adjusting member 7. The rotary drive mechanism 2 is connected to the movable plate 6 and can move relative to the movable plate 6 perpendicular to the first direction i. The driven seat 4 is connected to the fixed frame 5 and can move relative to the fixed frame 5 perpendicular to the first direction i. The adjusting member 7 is connected to the fixed frame 5 and is used to move the movable plate 6 relative to the fixed frame 5 parallel to the first direction i, so that the active seat 3 moves closer to or further away from the product 100. In other embodiments, the product 100 can also be connected to the active seat 3 and the driven seat 4 in other ways so that the active seat 3 can drive the driven seat 4 to rotate through the product 100.

[0035] In this embodiment, the adjusting member 7 is threadedly connected to the fixed frame 5, thereby allowing it to move parallel to the first direction i relative to the fixed frame 5. The position of the active seat 3 can be adjusted by turning the adjusting member 7, making operation convenient.

[0036] like Figure 3 and 4 As shown, in this embodiment, a fifth slide rail c1 is fixed on the fixed frame 5, and a fifth slider c2 is fixed on the movable plate 6. The fifth slider c2 is slidably connected to the fifth slide rail c1. The fifth slide rail c1 is set parallel to the first direction i. The fifth slide rail c1 and the fifth slider c2 are used to guide the movement of the movable plate 6 relative to the fixed frame 5, so as to facilitate the adjustment of the movable plate 6.

[0037] In this embodiment, the fixed rod 1 is fixedly connected to the movable plate 6, and the fixed rod 1 and the movable plate 6 move forward and backward together, which facilitates operation.

[0038] In this embodiment, the rotary drive mechanism 2 is a motor, the motor base is fixed on the second plate a6, and the output end of the motor is fixed on the active seat 3 by plugging in.
