Description

Technical Field

[0001] The present application relates to the technical field of building material inspection, and in particular to a cutting and positioning fixture for a waterstop strip peeling strength test piece. Background Art

[0002] During the sample preparation stage of the waterstop peel strength test, it is usually necessary to cut samples of a certain size from the waterstop specimen material and then test the samples.

[0003] At present, the main way to intercept the sample is to cut the waterstop specimen. Given that the waterstop itself has certain strength characteristics, this operation process is relatively cumbersome for the staff. During the cutting process, the staff needs to overcome the toughness of the waterstop, which often leads to uneven cutting edges, which will have an adverse effect on the test results and reduce the accuracy and reliability of the data. Utility Model Content

[0004] In order to improve the neatness of cutting of the specimen, the present application provides a waterstop peeling strength specimen cutting and positioning fixture.

[0006] A cutting and positioning fixture for a waterstop peeling strength specimen comprises: a first clamping seat, a second clamping seat and a locking assembly, wherein the second clamping seat moves relative to the first clamping seat so that a clamping gap for placing the specimen is formed between the first clamping seat and the second clamping seat, and the locking assembly connects the first clamping seat and the second clamping seat so that the second clamping seat moves to clamp the specimen together with the first clamping seat, and the sides of the first clamping seat and the second clamping seat both form cutting planes, and the cutting plane of the first clamping seat is flush with the cutting plane of the second clamping seat.

[0007] By adopting the above technical solution, after the first clamping seat and the second clamping seat clamp the waterstop specimen, the waterstop specimen can be cut along the cutting plane to guide the cutting direction of the waterstop specimen, so that the size of each specimen is similar and the incision is flat, and the cutting planes of the first clamping seat and the second clamping seat are flush so that it is not easily obstructed when cutting along the cutting plane, thereby improving the neatness of the cutting of the specimen and thus improving the test quality.

[0008] Optionally, the locking assembly includes a first locking group and a second locking group, the first locking group cooperates with one end of the first clamping seat and one end of the second clamping seat, the second locking group cooperates with the other end of the second clamping seat and the other end of the second clamping seat, and the cutting plane is located between the first locking group and the second locking group.

[0009] By adopting the above technical solution, the first locking group and the second locking group are respectively matched with the two ends of the first clamping seat and the second clamping seat to improve the stability of the first clamping seat and the second clamping seat when clamping the specimen, so as to evenly apply the clamping force to the specimen and prevent the specimen from being displaced during the cutting process.

[0010] Optionally, the first locking group includes:

[0011] A first extension seat, disposed at one end of the second clamping seat;

[0012] A first mounting seat, disposed at one end of the first clamping seat, forming a movable cavity for the first extension seat to extend into and slide; and

[0013] The first threaded member is threadedly connected to the first mounting seat and extends into the movable cavity. When the thread moves, the distance between the first threaded member and a surface of the first extending seat away from the first clamping seat is adjusted.

[0014] By adopting the above technical solution, the tightness of the first extension seat can be adjusted quickly and conveniently by adjusting the position of the first threaded member. Since the design of the first extension seat and the movable cavity has a certain tolerance, the position of the first extension seat can adapt to test pieces of different thicknesses to improve the adaptability of the device.

[0015] Optionally, a first limiting surface is formed between the first extending seat and the second clamping seat, and the first limiting surface is opposite to a surface of the first mounting seat facing the second clamping seat to limit the second clamping seat.

[0016] By adopting the above technical solution and setting the first limiting surface, the second clamping seat can be effectively restricted and guided during movement to prevent excessive movement of the second clamping seat, improve the accuracy of the clamping position of the second clamping seat, and help improve the progress of clamping the specimen.

[0017] Optionally, the second locking group includes:

[0018] A second extension seat, disposed at one end of the second clamping seat;

[0019] A second mounting seat is arranged at one end of the first clamping seat and forms a slot, and the second clamping seat is rotated away from one end of the second extension seat to drive the second extension seat to move toward the first clamping seat until it is pressed into the slot or to move away from the first clamping seat until it leaves the slot;

[0020] a rotating seat, hinged on the second mounting seat and having a clearance cavity, wherein when the second extension seat enters the clamping slot, the clearance cavity cooperates with the second extension seat when the rotating seat rotates, so that the rotating seat is always separated from the second extension seat; and

[0021] A second threaded member, threadedly connected to an end of the rotating seat away from the second mounting seat and extending into the clearance cavity;

[0022] Wherein, the rotating seat can be rotated until the second threaded member and the second extending seat are opposite to a side away from the first clamping seat.

[0023] By adopting the above technical solution, the second threaded member can be brought away from the position opposite to the second extension seat by the rotation of the rotating seat, so that the second clamping seat can drive the second extension seat to rotate away from the second mounting seat in a direction away from the first clamping seat, so as to expand the space between the first clamping seat and the second clamping seat, thereby facilitating the placement of the test piece between the first clamping seat and the second clamping seat. The rotation of the rotating seat and the threaded movement of the second threaded member can cooperate to quickly realize the locking and unlocking of the second extension seat, thereby improving the speed and convenience of operation.

[0024] Optionally, a second limiting surface is formed between the second extending seat and the second clamping seat, and the second limiting surface is opposite to a surface of the second mounting seat facing the second clamping seat to limit the second clamping seat.

[0025] By adopting the above technical solution, the clamping accuracy of the second clamping seat is optimized through the second limiting surface, thereby preventing the second clamping seat from excessive displacement.

[0026] Optionally, the first clamping seat is connected to a base, the base is located on a side of the first clamping seat away from the second clamping seat, and the orthographic projection size of the base is larger than the orthographic projection sizes of the first clamping seat and the second clamping seat.

[0027] By adopting the above technical solution, the addition of the base increases the contact area and weight of the entire device, making the device more stable during operation and preventing the device from tipping over during specimen cutting.

[0028] Optionally, the base is hollow inside.

[0029] By adopting the above technical solution, the material cost can be saved by designing the base to be hollow inside.

[0030] Optionally, the base is formed with an alignment surface flush with the cutting plane.

[0031] By adopting the above technical solution, the alignment surface is flush with the cutting plane, so that the specimen is not easily interfered by the base when being cut.

[0032] In summary, the present application includes at least one of the following beneficial effects:

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-4 This application is described in further detail.

[0042] The present application embodiment discloses a water stop strip peel strength test piece cutting and positioning fixture. Figure 1The cutting and positioning fixture for the waterstop strip peeling strength test piece includes a base 12, a first clamping seat 1, a second clamping seat 2 and a locking assembly. The first clamping seat 1 is mounted on the base 12 through the locking assembly, the second clamping seat 2 is relatively movable on the first clamping seat 1, and the locking assembly is matched with the first clamping seat 1 and the second clamping seat 2, so that the first clamping seat 1 and the second clamping seat 2 clamp the waterstop strip test piece together.

[0043] The base 12 includes a first rod 121 and a second rod 122. The first rod 121 and the second rod 122 are both hollow and made of hard metal. The middle of the first rod 121 is fixedly welded to one end of the second rod 122, so that the base 12 is T-shaped.

[0044] Reference Figure 1 and Figure 2 The first clamping seat 1 and the second clamping seat 2 are in the shape of a rectangular long rod with the same length extension direction, and the first clamping seat 1 and the second clamping seat 2 have the same extension width. The second clamping seat 2 is movable on the upper side of the first clamping seat 1 relative to the first clamping seat 1, so that a clamping gap 3 can be formed between the first clamping seat 1 and the second clamping seat 2 for the waterstop test piece to be placed.

[0045] One end of the first clamping seat 1 is fixedly installed in the middle of the first rod 121, and the other end of the first clamping seat 1 is installed on the end of the second rod 122 away from the first rod 121, and the common orthographic projection area of ​​the first rod 121 and the second rod 122 is larger than the orthographic projection area of ​​the first clamping seat 1 and the second clamping seat 2, so as to enhance the stability of the first clamping seat 1 and the second clamping seat 2 through the first rod 121 and the second rod 122.

[0046] The side surfaces on the opposite sides of the first clamping seat 1 and the side surfaces on the opposite sides of the second clamping seat 2 are both cutting planes 4, and the cutting planes 4 are vertical planes. The side surfaces of the first clamping seat 1 correspond to the side surfaces of the second clamping seat 2 one by one, and the side surfaces of the first clamping seat 1 are vertically flush with the opposite side surfaces of the second clamping seat 2, and the extension width of the second rod 122 is consistent with the extension width of the first clamping seat 1, and alignment surfaces 13 are formed on the opposite sides of the second rod 122, and the alignment surfaces 13 on both sides of the second rod 122 are respectively flush with the cutting planes 4 on both sides of the first clamping seat 1.

[0047] After the waterstop specimen is placed between the first clamping seat 1 and the second clamping seat 2 and clamped by the first clamping seat 1 and the second clamping seat 2, a cutting knife is used to cut the waterstop specimen along the cutting plane 4, so that the first clamping seat 1 and the second clamping seat 2 limit the movement of the clamped specimen relative to the cutting plane 4 during cutting, and the cutting plane 4 guides the cutting direction of the specimen.

[0048] Reference Figure 2The locking assembly includes a first locking group 5 and a second locking group 6. The first locking group 5 is matched with one end of the first clamping seat 1 and one end of the second clamping seat 2. The second locking group 6 is matched with the other end of the second clamping seat 2 and the other end of the second clamping seat 2. The cutting plane 4 and the clamping gap 3 are both located between the first locking group 5 and the second locking group 6.

[0049] Reference Figure 2 and Figure 3 In this embodiment, regarding the first locking assembly 5, the first locking assembly 5 includes a first extension seat 51, a first mounting seat 52 and a second threaded member 64. The first extension seat 51 is integrally formed at one end of the second clamping seat 2, and the first extension seat 51 extends away from the second clamping seat 2 along the length direction of the second clamping seat 2.

[0050] The first mounting seat 52 is fixedly welded to the upper surface of the middle portion of the first rod 121 . The first mounting seat 52 is U-shaped with its opening facing the first rod 121 . The inner cavity of the first mounting seat 52 forms an active cavity 7 . The first clamping seat 1 has a portion extending into the active cavity 7 and fixedly welded to the first mounting seat 52 .

[0051] The first extension seat 51 is in a square shape, and the first extension seat 51 slides in the movable cavity 7 of the first mounting seat 52 and is always located above the first mounting seat 52. Specifically, the first extension seat 51 can move up and down and rotate upward or downward in the movable cavity 7, thereby driving the second clamping seat 2 to move together. When the first extension seat 51 moves, the opposite sides are always in contact with the inner walls of the opposite sides of the first mounting seat 52, so as to limit the relative displacement of the cutting plane 4 of the first clamping seat 1 and the cutting plane 4 of the second clamping seat 2 in the horizontal direction.

[0052] Reference Figure 3 and Figure 4 The first threaded member 53 is a rod with threads, preferably a bolt in this embodiment, the rod body of the bolt moves along the vertical thread to the top of the first mounting seat 52, and the rod body of the bolt enters the movable cavity 7 downward and is opposite to the upper surface of the first extension seat 51.

[0053] When the specimen is placed between the first clamping seat 1 and the second clamping seat 2, the first extension seat 51 is first rotated upward in the movable cavity 7 to drive the second clamping seat 2 to move upward away from the first clamping seat 1, and then the specimen is placed on the first clamping seat 1, and then the second clamping seat 2 is moved downward so that the second clamping seat 2 abuts against the specimen, and the second clamping seat 2 is adjusted to be parallel to the first clamping seat 1, and then the first threaded member 53 is threadedly moved downward to abut against the upper surface of the first extension seat 51, limiting the first extension seat 51 from driving the second clamping seat 2 to move upward and separate from the specimen.

[0054] Reference Figure 2 and Figure 3In this embodiment, regarding the second locking assembly 6, the second locking assembly 6 includes a second extension seat 61, a second mounting seat 62, a rotating seat 63 and a second screw member 64. The second extension seat 61 is integrally formed at one end of the second clamping seat 2 away from the first extension seat 51, and the second extension seat 61 extends along the length direction of the second clamping seat 2 in a direction away from the second clamping seat 2.

[0055] The second mounting seat 62 is fixed to the upper surface of the end of the second rod 122 away from the first rod 121. A slot 9 is formed in the middle of the second mounting seat 62 and passes through the top of the second mounting seat 62. The slot 9 also passes through the two sides of the second mounting seat 62 facing away from the first mounting seat 52. The end of the first clamping seat 1 away from the first mounting seat 52 has a portion extending into the slot 9 and fixedly welded to the second mounting seat 62.

[0056] When the first extension seat 51 moves in the first mounting seat 52 until the second clamping seat 2 is parallel to the first clamping seat 1, the second extension seat 61 is inserted into the slot 9, and the end of the second extension seat 61 away from the second clamping seat 2 extends from the side of the second mounting seat 62 away from the first mounting seat 52. When the first extension seat 51 rotates in the first mounting seat 52 to drive the second clamping seat 2 to move upward away from the first clamping seat 1, the second extension seat 61 moves upward away from the second mounting seat 62.

[0057] A hinged seat is fixed on the side of the second mounting seat 62 facing away from the first mounting seat 52, and the rotating seat 63 is hinged on the hinged seat by connecting to a rotating shaft rotating on the hinged seat, and the rotating axis of the rotating seat 63 is parallel to the width direction of the second clamping seat 2, wherein the rotating shaft can be made of a bolt or a pin.

[0058] The rotating seat 63 is a U-shaped structure with its opening facing the second mounting seat 62, and the inner cavity of the rotating seat 63 forms a clearance cavity 10, which is used to make way for the second extension seat 61 inserted into the slot 9 when the rotating seat 63 rotates, so that the rotating seat 63 does not interfere with the second extension seat 61 when rotating.

[0059] The second threaded member 64 is a rod with threads, preferably a bolt in this embodiment, the rod of the bolt is threadedly connected to the end of the rotating seat 63 away from the second mounting seat 62 and extends into the clearance cavity 10, and the thread movement direction of the second threaded member 64 is perpendicular to the rotation axis direction of the rotating seat 63.

[0060] Reference Figure 2 and Figure 3When the first threaded member 53 is pressed against the upper surface of the first extension seat 51 and the second threaded member 64 is inserted into the slot 9, the rotating seat 63 is rotated upward until the second threaded member 64 is located directly above the first extension seat 51, and then the second threaded member 64 is threaded downward until it is pressed against the upper surface of the second extension seat 61 to limit the second extension seat 61 from moving upward from the second mounting seat 62, thereby positioning the second clamping seat 2 relative to the first clamping seat 1.

[0061] Reference Figure 3 Furthermore, the extension widths of the first extension seat 51 and the second extension seat 61 are both smaller than the extension width of the second clamping seat 2, so that the end surface of the second clamping seat 2 close to one end of the first extension seat 51 forms a first limiting surface 8, and the first limiting surface 8 is opposite to and close to a surface of the first mounting seat 52 facing the second mounting seat 62 when the first extension seat 51 moves. The end surface of the second clamping seat 2 close to one end of the second extension seat 61 forms a second limiting surface 11, and the second limiting surface 11 is opposite to and close to a surface of the second mounting seat 62 facing the first mounting seat 52 when the second extension seat 61 is inserted into the second mounting. Therefore, when the second clamping seat 2 cooperates with the first clamping seat 1, it is limited between the first mounting seat 52 and the second mounting seat 62 to improve the accuracy of the position of the second clamping seat 2.

[0062] In addition, the second extension seat 61 is moved away from the second mounting seat 62, and the first extension seat 51 is removed from the first mounting seat 52, so that the first clamping seat 1 and the second clamping seat 2 can be completely separated, so as to facilitate the maintenance and replacement of the clamp.

[0063] In other embodiments, the structures of the first locking group 5 and the second locking group 6 may be consistent with the structure of the first locking group 5 in this embodiment, or the structures of the first locking group 5 and the second locking group 6 may be consistent with the structure of the second locking group 6 in this embodiment.

[0064] The implementation principle of the waterstop strip peeling strength test piece cutting and positioning fixture of the embodiment of the present application is: first rotate the rotating seat 63 away from the second mounting seat 62 until the second threaded member 64 is away from the upper surface of the second extension part, then lift the second clamping seat 2 upward by rotating the first extension part, and then place the waterstop strip test piece on the first clamping seat 1. Then rotate the second clamping seat 2 downward so that the second clamping seat 2 and the first clamping seat 1 clamp the waterstop strip test piece together, and then rotate the rotating seat 63 until the second threaded member 64 is opposite to the upper surface of the second extension part, and tighten the first extension part by the first threaded member 53 and the second extension part by the second threaded member 64 to position the second clamping seat 2.

[0065] After the waterstop specimen is positioned and clamped between the first clamping seat 1 and the second clamping seat 2, the waterstop specimen is cut along the cutting plane 4 to be cut into test specimens.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
