Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a slide rail positioning type weld strength testing fixture. Background Technology

[0002] After welding is completed, it is usually necessary to test the weld strength of the welded part. During the testing process, in order to maintain the stability of the welded object, it is usually necessary to use a clamp to limit the welded object.

[0003] In practical work, the existing testing fixtures have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] During use, clamping is usually achieved by two clamping plates facing each other and clamping and fixing the object. At this time, the object can only be limited on the opposite sides. During the testing process, when the object is subjected to an impact from an external testing force, it is easy to cause the object to separate from the clamping plates, thus affecting the clamping effect.

[0005] Therefore, this utility model provides a slide rail positioning type weld strength testing fixture. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a slide rail positioning type weld strength testing fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a slide rail positioning type weld strength testing fixture, comprising a base frame, a multi-directional positioning structure provided on the top of the base frame, the multi-directional positioning structure including a mounting plate, the bottom of the mounting plate being fixedly connected to the top of the base frame, a hydraulic telescopic rod being fixedly installed on one side of the mounting plate, and a U-shaped clamping plate being fixedly connected to the output end of the hydraulic telescopic rod; an adjusting support structure is provided inside the base frame, the adjusting support structure including an auxiliary plate, the two sides of the auxiliary plate being fixedly connected to the two sides of the base frame, and a drive motor being fixedly installed on the bottom of the auxiliary plate.

[0008] In a preferred embodiment, a fixing plate is fixedly connected to the top of the bottom frame, and a rectangular protrusion is fixedly connected to one side of the fixing plate. A guide rail groove is symmetrically formed on the top of the bottom frame, and a guide rail slider is slidably connected to the inner wall of the guide rail groove. The top of the guide rail slider is fixedly connected to the bottom of the U-shaped clamping plate. First screws are threadedly connected to the inner walls of both sides of the U-shaped clamping plate. An operating block is fixedly connected to one end of each first screw, and a clamping plate is rotatably connected to the other end of each first screw. A limit rod is fixedly connected to one side of the clamping plate, and the limit rod is slidably disposed on the inner wall of the U-shaped clamping plate.

[0009] The technical effect of adopting the above-mentioned further solution is that by setting a fixing plate and a U-shaped clamping plate, the welded object (hereinafter referred to as the welded object) that needs to be tested for weld strength can be fixed in conjunction with the hydraulic telescopic rod. At this time, in conjunction with the first screw and the clamping plate, the welded object is reinforced and clamped. At this time, the four sides of the welded object can be fixed, making the fixing of the welded object more stable and preventing it from easily detaching.

[0010] In a preferred embodiment, the output end of the drive motor is fixedly connected to a second screw, the outer surface of the second screw is threadedly connected to a screw-hole cylinder, the top of the screw-hole cylinder is fixedly connected to a support plate, the top of the bottom frame is provided with a rectangular through slot, the outer surface of the screw-hole cylinder is fixedly connected to an auxiliary connecting plate, a rectangular sliding groove is provided on one side of the bottom frame, a rectangular slider is slidably connected to the inner wall of the rectangular sliding groove, and one side of the rectangular slider is fixedly connected to one side of the auxiliary connecting plate.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the second screw and the screw hole cylinder, the support plate can be driven to move, so that the height of the welded object placed on the support plate can be adjusted, which makes it easier for the U-shaped clamp and the clamping plate to clamp and fix the welded object.

[0012] In a preferred embodiment, a number of rubber protrusions are fixedly connected to the top of the support plate.

[0013] The technical effect of adopting the above-mentioned further solution is that the rubber protrusions on the support plate can increase the friction between the welded object and the support plate, so that when the welded object is placed on the support plate, it can be placed stably and will not easily separate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a multi-directional positioning structure, the U-shaped clamp and the fixing plate can assist in limiting the opposite sides of the weldment, thus ensuring its stable fixation. Simultaneously, the first screw and the clamping plate can assist in clamping and limiting the other two sides of the weldment, ensuring it is securely held and preventing positional shifts during testing that could affect the results. By setting up an adjustable support structure, the second screw and the screw-hole cylinder can move the support plate up and down, allowing for height adjustment of the weldment placed on the support plate. It is important to note that the height adjustment of the support plate is related to the height of the guide rail slider; the support plate cannot exceed the height of the guide rail slider. This ensures that the U-shaped clamp and the clamping plate can better clamp the weldment, improving the clamping effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, this embodiment provides a technical solution: a slide rail positioning type weld strength testing fixture, including a base frame 1, a multi-directional positioning structure 2 on the top of the base frame 1, the multi-directional positioning structure 2 including a mounting plate 23, the bottom of the mounting plate 23 being fixedly connected to the top of the base frame 1, a hydraulic telescopic rod 24 being fixedly installed on one side of the mounting plate 23, and a U-shaped clamping plate 25 being fixedly connected to the output end of the hydraulic telescopic rod 24; an adjustment support structure 3 is provided inside the base frame 1, the adjustment support structure 3 including an auxiliary plate 31, the two sides of the auxiliary plate 31 being fixedly connected to the two sides of the base frame 1, and a drive motor 32 being fixedly installed at the bottom of the auxiliary plate 31. By setting the multi-directional positioning structure 2, the opposite sides of the welded object can be assistedly limited under the action of the U-shaped clamping plate 25 and the fixed plate 21, thereby making... The welded object can be fixed firmly. Simultaneously, under the action of the first screw 28 and the clamping plate 210, the other two sides of the welded object are further clamped and limited, ensuring a stable clamping and preventing positional displacement during testing, which could affect the test results. By setting an adjustable support structure 3, the second screw 33 and the screw-hole cylinder 34 can drive the support plate 39 to move up and down, thereby adjusting the height of the welded object placed on the support plate 39. It should be noted that the height adjustment of the support plate 39 is related to the height of the guide rail slider 26; that is, the support plate 39 cannot be higher than the height of the guide rail slider 26. This allows the U-shaped clamping plate 25 and the clamping plate 210 to better clamp the welded object, improving the clamping effect.

[0026] Going a step further, such as Figures 2-3 As shown: A fixing plate 21 is fixedly connected to the top of the bottom frame 1. A rectangular protrusion 22 is fixedly connected to one side of the fixing plate 21. Guide rail grooves 27 are symmetrically opened on the top of the bottom frame 1. Guide rail sliders 26 are slidably connected to the inner wall of the guide rail grooves 27. The top of the guide rail sliders 26 is fixedly connected to the bottom of the U-shaped clamping plate 25. First screws 28 are threadedly connected to the inner walls of both sides of the U-shaped clamping plate 25. An operating block 29 is fixedly connected to one end of the first screw 28, and a clamping plate 210 is rotatably connected to the other end of the first screw 28. A limiting rod 211 is fixedly connected to one side of the clamping plate 210. The limiting rod 211 is slidably set on the inner wall of the U-shaped clamping plate 25. By setting the fixing plate 21 and the U-shaped clamping plate 25, the welded object (hereinafter referred to as the welded object) that needs to be tested for weld strength can be fixed in conjunction with the hydraulic telescopic rod 24. At this time, the welded object is reinforced and clamped in conjunction with the first screw 28 and the clamping plate 210. At this time, the four sides of the welded object can be fixed, making the fixing of the welded object more stable and preventing it from easily falling off.

[0027] The above solutions also have the problem that the welded object needs to be held between the U-shaped clamp 25 and the fixing plate 21 for clamping, which is very inconvenient. Figure 2 and Figure 4As shown: In this scheme, the output end of the drive motor 32 is fixedly connected to a second screw 33, the outer surface of the second screw 33 is threadedly connected to a screw hole cylinder 34, the top of the screw hole cylinder 34 is fixedly connected to a support plate 39, the top of the bottom frame 1 is provided with a rectangular through groove 38, the outer surface of the screw hole cylinder 34 is fixedly connected to an auxiliary connecting plate 35, one side of the bottom frame 1 is provided with a rectangular sliding groove 36, the inner wall of the rectangular sliding groove 36 is slidably connected to a rectangular slider 37, one side of the rectangular slider 37 is fixedly connected to one side of the auxiliary connecting plate 35. Under the action of the second screw 33 and the screw hole cylinder 34, the support plate 39 can be driven to move, so that the height of the welding object placed on the support plate 39 can be adjusted, which makes it easier for the U-shaped clamp 25 and the clamping plate 210 to clamp and fix the welding object.

[0028] The above solutions also have the problem that the welded parts placed on top of the support plate 39 are prone to slipping off, such as... Figure 4 As shown, a number of rubber protrusions 310 are fixedly connected to the top of the support plate 39. The rubber protrusions 310 on the support plate 39 can increase the friction between the welded object and the support plate 39, so that when the welded object is placed on the support plate 39, it can be placed stably and will not easily separate.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use, the workpiece is placed on top of the support plate 39. The drive motor 32 is then started, which causes the second screw 33 to drive the screw hole cylinder 34 to move, which in turn drives the auxiliary connecting plate 35 and the rectangular slider 37 to move along the rectangular slide groove 36, which in turn drives the support plate 39 to move.

[0032] After moving to the appropriate position, the hydraulic telescopic rod 24 is activated, allowing the U-shaped clamping plate 25 to work with the fixing plate 21 to clamp the welded object. At the same time, the operating block 29 can be rotated, which in turn drives the first screw 28 to rotate, allowing the clamping plate 210 to move. This provides auxiliary fixation and clamping for the welded object. During the movement of the U-shaped clamping plate 25, the guide rail slider 26 can slide on the inner wall of the guide rail groove 27, making the movement of the U-shaped clamping plate 25 more stable.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
