Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing, specifically to a weld tensile testing device. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature, or high pressure. During welding, the point where the weld is made is called the weld seam. To ensure the quality and reliability of the weld, a tensile test is performed on the weld seam using a tensile testing machine to measure the maximum stress the weld seam can withstand during tensile testing.

[0003] However, in the above-mentioned scheme, the tensile testing machine is usually fixed with a protective net on its outside. Although the protective net can prevent the product from splashing outward when it breaks, it will hinder the operator from inspecting and maintaining the tensile testing machine. Utility Model Content

[0004] This utility model proposes a weld tensile strength testing device. By setting a fixing component, the first protective cylinder is moved downward, causing the first protective cylinder to move the locking block downward. The locking block then moves the supporting ring downward. The first protective cylinder is then rotated, causing the locking block to rotate as well. When the limiting post rotates to the position corresponding to the limiting groove, the limiting post enters the limiting groove under the elastic force of the telescopic spring, fixing the first protective cylinder. This facilitates installation and disassembly without obstructing the operator.

[0005] Therefore, the technical solution adopted is as follows:

[0006] A weld tensile testing device includes a tensile testing machine assembly, the tensile testing machine assembly including a base; it also includes a fixing assembly, the fixing assembly including an annular groove and a first protective cylinder formed on the base, the annular groove having a vertically arranged telescopic spring inside, the top of the telescopic spring having a support ring matching the annular groove fixed to it, the upper part of the support ring having a limiting block fixed to the groove, the bottom of the limiting block having a limiting groove, the bottom of the first protective cylinder being sleeved inside the annular groove and having a locking block fixed thereon, the locking block having a limiting post matching the limiting groove fixed thereon.

[0007] A further technical solution is that the tensile testing machine assembly also includes a support frame, a movable plate, and clamps. The support frame is fixed on the base, the movable plate is slidably connected to the inner side of the support frame, and the clamps are respectively fixedly connected to the upper end of the base and the bottom of the movable plate, which are arranged opposite to each other.

[0008] A further technical solution is that the limiting block and the card block each have a relative number of them.

[0009] A further technical solution is that the sidewall of the first protective cylinder has a honeycomb structure.

[0010] A further technical solution includes an adjustment component, which includes a fixing plate vertically fixed to the outer wall of the first protective cylinder. The fixing plate has a vertically arranged sliding groove, and one side of the sliding groove may have a plurality of vertically arrayed fixing holes. The sliding groove and the fixing holes are connected by a sliding channel. A second protective cylinder is sleeved inside the first protective cylinder. A support plate is fixed to the outer wall of the second protective cylinder, and a fixing block is fixed to the bottom of the support plate. The fixing block can be inserted into the fixing hole and matched and fixed thereto.

[0011] A further technical solution is that a first fixing ring is fixed to the bottom of the first protective cylinder, and a second fixing ring is fixed to the outer wall of the second protective cylinder. The fixing plate and the support plate are respectively fixed to the first fixing ring and the second fixing ring.

[0012] The beneficial effects of this application are as follows: The weld tensile strength testing device provided by this application, by setting a fixing component, moves the first protective cylinder downward, causing the first protective cylinder to drive the locking block to move downward, and the locking block to drive the supporting ring to move downward. Then, the first protective cylinder is rotated, causing the first protective cylinder to drive the locking block to rotate. When the limiting post rotates to the position corresponding to the limiting groove, under the elastic force of the telescopic spring, the limiting post enters the limiting groove and fixes the first protective cylinder. This facilitates installation and disassembly without obstructing the operator. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this application provides a weld tensile testing device, including a tensile testing machine assembly, the tensile testing machine assembly including a base 11; and a fixing assembly, the fixing assembly including an annular groove 21 and a first protective cylinder 26 formed on the base 11, the annular groove 21 having a vertically arranged telescopic spring 22 inside, the top of the telescopic spring 22 having a support ring 23 matching the annular groove 21 fixed to the top, the support ring 23 having a limiting block 24 fixed to the groove above the supporting ring 23, the bottom of the limiting block 24 having a limiting groove 25 formed at the bottom, the bottom of the first protective cylinder 26 being sleeved inside the annular groove 21 and having a locking block 27 fixed thereon, the locking block 27 having a limiting post 28 matching the limiting groove 25 fixed thereon.

[0024] To ensure stable connection, both the limiting block 24 and the locking block 27 have a certain number of corresponding blocks. The sidewall of the first protective cylinder 26 has a honeycomb structure.

[0025] The annular slot 21 is used to place the support ring 23 and the locking block 27. The telescopic spring 22 is used to reset the support ring 23. The support ring 23 is used to support the locking block 27. The limiting block 24 is used to limit the locking block 27. The limiting groove 25 is used to engage with the limiting post 28. The first protective cylinder 26 is used to shield the clamp 14 on the base 11. The locking block 27 is used to support the limiting post 28.

[0026] The tensile testing machine assembly also includes a support frame 12, a movable plate 13, and a clamp 14. The support frame 12 is fixed on the base 11, the movable plate 13 is slidably connected to the inner side of the support frame 12, and the clamp 14 is fixedly connected to the upper end of the base 11 and the bottom of the movable plate 13 respectively and is arranged opposite to each other.

[0027] The base 11 is used to support the support frame 12, the support frame 12 is used to support the movable plate 13, the movable plate 13 is used to drive the clamp 14 to move and move along the inner side of the support frame 12, and the clamp 14 is used to clamp the test product.

[0028] The supporting ring 23 is slidably connected to the inside of the annular slot 21, and the bottom end of the locking block 27 is in contact with the top end of the supporting ring 23.

[0029] The support ring 23 can slide up and down inside the annular groove 21. When the support ring 23 slides down, it will cause the telescopic spring 22 to be compressed.

[0030] When the bottom end of the limiting block 24 and the top end of the locking block 27 come into contact, the limiting post 28 is located inside the limiting groove 25.

[0031] The first protective cylinder 26 is located outside the clamp 14, and the bottom end of the first protective cylinder 26 is flush with the bottom end of the clamping block 27.

[0032] Working principle: During weld testing, to prevent spatter from splashing onto the test product, the first protective cylinder 26 is fitted onto the outside of the clamp 14 on the base 11, and the first protective cylinder 26 is moved downwards. This downward movement of the first protective cylinder 26 causes the locking block 27 to move downwards. When the locking block 27 contacts the upper end of the supporting ring 23, the locking block 27 causes the supporting ring 23 to slide downwards along the annular groove 21, compressing the telescopic spring 22. Rotating the first protective cylinder 26 further compresses the first protective cylinder. The rotation of the protective cylinder 26 causes the locking block 27 and the limiting post 28 to rotate. When the locking block 27 moves the limiting post 28 to below the limiting block 24, the force applied to the first protective cylinder 26 stops. Under the elastic force of the telescopic spring 22, the supporting ring 23 moves the locking block 27 upward so that the limiting post 28 enters the limiting groove 25. At this time, the limiting block 24 limits the locking block 27 and the limiting post 28, so that the first protective cylinder 26 can be fixed on the outside of the clamp 14 on the base 11 for protection.

[0033] Please see Figure 5 and Figure 6 As shown, this embodiment, based on the above embodiment, further includes:

[0034] The adjustment assembly includes a fixing plate 32 vertically fixed to the outer wall of the first protective cylinder 26. The fixing plate has a vertically arranged sliding groove 33. One side of the sliding groove 33 may have a plurality of vertically arrayed fixing holes 34. The sliding groove 33 and the fixing holes 34 are connected by a sliding channel. A second protective cylinder 35 is sleeved inside the first protective cylinder 26. A support plate 37 is fixed to the outer wall of the second protective cylinder 35. A fixing block 38 is fixed to the bottom of the support plate 37. The fixing block 38 can be inserted into the fixing holes 34 and matched and fixed thereto.

[0035] Furthermore, a first fixing ring 31 is fixed to the bottom of the first protective cylinder 26, and a second fixing ring 36 is fixed to the outer wall of the second protective cylinder 35. The fixing plate 32 and the support plate 37 are respectively fixed to the first fixing ring 31 and the second fixing ring 36.

[0036] The first fixing ring 31 is used to support the fixing plate 32, the fixing hole 34 is used to limit the fixing block 38, the second protective cylinder 35 is used to cover the outside of the clamp 14 at the lower end of the movable plate 13, the second fixing ring 36 is used to support the support plate 37, the support plate 37 is used to limit the fixing block 38, and the fixing block 38 is used to limit the second protective cylinder 35.

[0037] The fixing block 38 can slide along the inside of the slide groove 33 and move into the fixing hole 34, and the fixing block 38 will be locked into the fixing hole 34 under the action of gravity.

[0038] Working principle: When the length of the first protective cylinder 26 needs to be adjusted to cover the outside of test products of different lengths, the support plate 37 is moved upward to make the fixing block 38 disengage from the fixing hole 34 and move from the sliding channel to the inside of the slide groove 33. At this time, the support plate 37 can move up and down arbitrarily inside the slide groove 33. Moving the support plate 37 drives the second protective cylinder 35 to slide synchronously inside the first protective cylinder 26, so that the distance between the bottom end of the first protective cylinder 26 and the top end of the second protective cylinder 35 changes. After the distance is determined, the support plate 37 is rotated horizontally to make the fixing block 38 re-engage from the sliding channel into the fixing hole 34, so that the second protective cylinder 35 is fixed to the first protective cylinder 26 again.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
