DETAILED DESCRIPTION
[0036] The following is a combination of the appended examples of the present invention Figures 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventing novel work are within the scope of protection of the present invention.
[0037] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
[0038] Combine Figures 1-4 As shown, the utility model provides a jig for fixing the product to be welded to prevent the product to be welded from moving during the welding process, thereby improving the welding quality.
[0039] Specifically, the product to be welded includes a first part to be welded and a second part to be welded placed on the first part to be welded.
[0040] The fixture includes a support base 101 and a cover plate 102, wherein Figure 1 As shown, the support base 101 is provided with a first positioning portion 101a, which is used to position the first workpiece to be welded. It is understood that the shape and structure of the first positioning portion 101a are not limited, as long as the shape and structure can achieve positioning of the first workpiece to be welded and prevent the first workpiece from moving during the welding process, it falls within the scope of protection of the present invention.
[0041] The cover plate 102 is buckled onto the support base 101 and presses the second part to be welded onto the first part to be welded. Specifically, the second part to be welded can be placed on the first part to be welded first, and then the cover plate 102 is pressed onto the second part to be welded and connected to the support base 101 to press the second part to be welded onto the first part to be welded.
[0042] The cover plate 102 is provided with a second positioning portion 102a at one end thereof where the second piece to be welded is pressed. Figure 3 As shown, the second positioning portion 102a is used to position the second workpiece to be welded. The second positioning portion 102a prevents the second workpiece to be welded from moving during the welding process.
[0043] For example, if the first component to be welded is a motor and the second component to be welded is a PCBA, when using the jig, the motor is placed on support base 101 and positioned using first positioning portion 101a. Next, the PCBA is placed on the motor, and cover plate 102 is placed on the PCBA, positioning the PCBA using second positioning portion 102a. Finally, cover plate 102 is locked to support base 101. The combination of cover plate 102 and support base 101 ensures the relative position of the motor and PCBA is fixed, preventing movement during welding and improving welding stability. Furthermore, the provision of cover plate 102 effectively protects the components on the second component to be welded, preventing them from being burned by high temperatures or tinning.
[0044] In one embodiment of the present invention, the fixture further includes a welding base 103, such as Figure 4As shown, one end of the cover plate 102 facing away from the support base 101 is mounted on the welding base 103. The arrangement of the welding base 103 provides a mounting base for the cover plate 102 and the support base 101.
[0045] In this embodiment, when the jig is used, the product to be welded is first placed on the support base 101; then, the cover plate 102 is placed on the product to be welded; then, the cover plate 102 is locked to the support base 101 to form an integrated product structure; finally, the assembled integrated product structure is placed upside down on the welding base 103 to perform welding operations.
[0046] The provision of the welding base 103 further improves the stability of the product to be welded.
[0047] In one embodiment of the present invention, at least one accommodating groove 103a is provided on the welding base 103, wherein the accommodating groove 103a is adapted to the shape of the cover plate 102, so as to facilitate the positioning and installation of the cover plate 102 and the welding base 103, thereby improving the efficiency of installing the integrated product structure on the welding base 103.
[0048] In order to improve welding efficiency, an embodiment of the present invention discloses that the number of accommodating grooves 103a is greater than or equal to 2, and each accommodating groove 103a is arranged at intervals on the welding base 103. The number of accommodating grooves 103a can be equal to the number of integrated product structures, and are arranged one-to-one to achieve simultaneous welding of multiple products to be welded.
[0049] In order to facilitate the quick installation of the cover plate 102 and the welding base 103, the circumferential side wall of the cover plate 102 is provided with a first foolproof notch 102b, and the groove wall of the receiving groove 103a is provided with a first foolproof protrusion 103b, wherein the first foolproof protrusion 103b is adapted to the first foolproof notch 102b, so that the cover plate 102 can be stably limited in the receiving groove 103a. Figure 3 As shown, taking the cover plate 102 as a square plate and the receiving groove 103a as a square groove as an example, the number of the first foolproof protrusions 103b is four, respectively set at the four corners of the cover plate 102. Correspondingly, the number of the first foolproof protrusions 103b is also four, respectively set at the four corners of the receiving groove 103a, and the first foolproof protrusions 103b are arranged in a one-to-one correspondence with the first foolproof notches 102b. It can be understood that the sizes of the first foolproof protrusions 103b at different positions are different, and correspondingly, the sizes of the first foolproof notches at different positions are different, so as to avoid the problem of incorrect installation of the cover plate 102, so that the cover plate 102 can only be rotated into the receiving groove 103a in one direction, and cannot be rotated in other directions.
[0050] It should be noted that the above-mentioned disclosure of the first anti-foolproof notch 102b on the cover plate 102 and the first anti-foolproof protrusion 103b in the accommodating groove 103a is only a specific embodiment of the present invention. In actual applications, the first anti-foolproof notch 102b can also be provided on the groove wall of the accommodating groove 103a, and the first anti-foolproof protrusion 103b can be provided on the circumferential side wall of the cover plate 102, etc.
[0051] It should also be noted that the following can be simultaneously or separately provided: a second fool-proof notch can be provided on the circumferential side wall of the cover plate 102 or the wall of the receiving groove 103a, and a second fool-proof protrusion that matches the second fool-proof notch can be provided on the other. In other words, the second fool-proof notch can be provided on the circumferential side wall of the cover plate 102, and the second fool-proof protrusion that matches the second fool-proof notch can be provided on the wall of the receiving groove 103a; or the second fool-proof notch can be provided on the wall of the receiving groove 103a, and the second fool-proof protrusion that matches the second fool-proof notch can be provided on the circumferential side wall of the cover plate 102.
[0052] Specifically, the second foolproof protrusion can be the same as or different from the first foolproof protrusion 103b; correspondingly, the second foolproof notch can be the same as or different from the first foolproof notch 102b. For example, if the first foolproof protrusion 103b is a square protrusion and the first foolproof notch 102b is a square notch, the second foolproof protrusion can be a square protrusion or an arc-shaped protrusion, etc., and correspondingly, the second foolproof notch can be a square notch or an arc-shaped notch, etc.
[0053] In one embodiment of the present invention, the second positioning portion 102a includes a limiting groove formed on the cover plate 102 for limiting the position of the second part to be welded. Specifically, the shape of the limiting groove matches the shape of the second part to be welded, so as to facilitate the positioning of the second part to be welded.
[0054] It should be noted that the positioning of the second part to be welded is not limited to being achieved through the limiting groove. The second positioning portion 102a can also be provided with multiple positioning blocks installed on the cover plate 102, and the multiple positioning blocks are respectively used to position various positions of the circumferential side wall of the second part to be welded.
[0055] In one embodiment of the present invention, Figure 2 As shown, the support base 101 includes a support frame 101-1 and a support plate 101-2, wherein the support plate 101-2 is installed on the support frame 101-1, that is, the support frame 101-1 is used to support the support plate 101-2 to elevate the support plate 101-2.
[0056] The first positioning portion 101a comprises a positioning slot formed on the support plate 101-2. The positioning slot is used to position the first component to be welded. Specifically, the positioning slot matches the shape of the first component to be welded to achieve proper positioning. If the first component to be welded is a motor, a through hole 101c is defined within the positioning slot to allow the motor shaft to pass through. Because the support frame 101-1 elevates the support plate 101-2, the motor is elevated, ensuring that the motor shaft is free of stress and preventing collapse.
[0057] Attached to both sides of the support plate 101-2 are snap-fit components 101-3, which are used to snap-fit the cover plate 102, thereby achieving quick snap-fitting of the cover plate 102. Specifically, the snap-fit components 101-3 can be snap buckles, etc., and correspondingly, the cover plate 102 is provided with snap-fit holes 102c, etc., which snap-fit to the snap connectors.
[0058] It should be noted that setting the clamping member 101-3 as a buckle is only a specific embodiment of the present invention. In actual applications, it can also be set to other clamping methods, for example, the clamping member 101-3 is a hook, and the hook is set to hook the edge of the cover 102.
[0059] In one embodiment of the present invention, the fixed end of the clamping member 101-3 is fixed on the support plate 101-2, and the clamping end extends in a direction away from the support plate 101-2. Specifically, the fixed end of the clamping member 101-3 is detachably mounted on the edge of the support plate 101-2 by fasteners such as bolts. In order to prevent the bolts and other fasteners from being loosened due to long-term stress and high temperature of the fixture, thread glue or the like can be injected at the connection between the bolts and other fasteners and the cover plate 102.
[0060] The clamping end of the clamping member 101 - 3 is hinged to the fixed end of the clamping member 101 - 3 , that is, the clamping end of the clamping member 101 - 3 can be bent to facilitate clamping or unlocking with the cover plate 102 .
[0061] The cover plate 102 is provided with engaging holes 102c. The number of the engaging holes 102c is equal to the number of the engaging members 101-3 and they are arranged in a one-to-one correspondence. The engaging holes 102c are used to engage the engaging ends of the engaging members 101-3.
[0062] Specifically, the clamping end of the clamping member 101 - 3 may be set as a clamping ring, and a clamping protrusion for clamping the clamping ring may be set in the clamping hole 102 c.
[0063] In one embodiment of the present invention, Figure 1 As shown, a positioning hole 101b is provided in the positioning groove, and the positioning groove realizes the rough positioning of the first workpiece to be welded, while the positioning hole 101b realizes the precise positioning of the first workpiece to be welded by positioning and plugging with the first workpiece to be welded.
