Description

Technical Field

[0001] This utility model relates to a quick-locking tooling fixture, belonging to the field of machinery. Background Technology

[0002] In existing technologies, when conducting mechanical performance tests on columns, it is typically necessary to first weld a base plate to the end of the column under test, and then connect the base plate to the test fixture using bolts to fix the column horizontally to the test fixture. The additional welding of the base plate not only increases testing costs but also prolongs the test preparation cycle. Furthermore, when testing columns of different specifications, it is usually necessary to change the test fixture to match the welded base plate, resulting in poor versatility of the test fixture. In addition, the weld connection between the column end and the base plate is relatively weak and prone to plastic deformation under dynamic loads. The weld often cracks first due to excessive stress, affecting the accuracy of the test.

[0003] Therefore, it is necessary to provide a new quick-locking tooling fixture to solve the above problems. Utility Model Content

[0037] Please refer to Figures 1 to 12 As shown, this utility model discloses a quick-locking fixture 100 for positioning a column 200 on a test platform 300. The column 200 includes a web 201 and flanges 202. In a specific embodiment, the column 200 is preferably an H-beam or a C-beam, and there are two flanges 202 located at opposite ends of the web 201, with the web 201 perpendicular to the flanges 202.

[0038] The quick-lock fixture 100 includes a base plate 1, a side plate 2, and multiple connectors 3. The base plate 1 is fixedly connected to the test platform 300. The side plate 2 is vertically mounted on the base plate 1. The side plate 2 is provided with multiple waist-shaped holes 20, including a first hole group and a second hole group. The first hole group is used to connect the column 200 in the first state, and the second hole group is used to connect the column 200 in the second state. The connectors 3 include a first plate surface 31 and a second plate surface 32 integrally bent and extended from the first plate surface 31. The first plate surface 31 is detachably connected to the side plate 2 through the first hole group or the second hole group. The second plate surface 32 is configured to be detachably connected to the web plate 201 or the wing plate 202.

[0039] In this embodiment, both the first-state and second-state column 200 are horizontally placed. The wing plate 202 of the first-state column 200 is perpendicular to the base plate 1, while the wing plate 202 of the second-state column 200 is parallel to the base plate 1. Specifically, when the column 200 is fixedly connected to the side plate 2 through the first hole group, the wing plate 202 of the column 200 is perpendicular to the base plate 1; when the column 200 is fixedly connected to the side plate 2 through the second hole group, the wing plate 202 of the column 200 is parallel to the base plate 1. This configuration allows the column 200 to be horizontally fixed to the side plate 2 in either the first or second state to meet different testing requirements.

[0040] Furthermore, the first plate surface 31 of the connector 3 is detachably connected to the side plate 2, and the second plate surface 32 of the connector 3 is detachably connected to the web plate 201 or wing plate 202 of the column 200. This allows the column 200 to be directly fixedly installed on the side plate 2 without the need to weld the column base plate, reducing testing costs and shortening the testing preparation cycle. In addition, the side plate 2 is provided with multiple waist-shaped holes 20. By moving the connector 3 along the length direction of the waist-shaped holes 20, the spacing of the multiple connectors 3 can be changed, thereby adapting to columns 200 of different specifications and significantly improving the versatility and applicability of the quick-lock tooling fixture 100.

[0041] Furthermore, the quick-lock fixture 100 of this utility model also includes multiple reinforcing members, which are fixedly connected to the base plate 1 and the side plate 2 to increase the strength of the side plate 2 and prevent damage to the side plate 2 due to excessive force applied during the testing of the column 200. In a specific embodiment, reinforcing members are provided on both opposite sides of the side plate 2 to provide relatively balanced support force, effectively improving the bending resistance of the side plate 2, and thus improving the support strength of the quick-lock fixture 100.

[0042] Please refer to Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the first hole group includes a first waist-shaped hole 211 extending longitudinally along a first direction. When the first plate surface 31 of the connector 3 is connected to the side plate 2 through the first waist-shaped hole 211, the second plate surface 32 is used to connect to the wing plate 202 of the column 200 in the first state; please refer to Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the second hole group includes a second waist-shaped hole 221 extending longitudinally along the first direction. When the first plate surface 31 of the connector 3 is connected to the side plate 2 through the second waist-shaped hole 221, the second plate surface 32 is used to connect the web plate 201 of the column 200 in the second state.

[0043] Specifically, refer to Figure 10 The first direction is the X direction (also known as the left-right direction) which extends horizontally relative to the base plate 1, and the second direction is the Y direction (also known as the up-down direction) which extends vertically relative to the base plate 1.

[0044] By setting up the first and second hole groups in this way, the column 200 can switch between the first and second states to meet different testing requirements.

[0045] Please refer to Figure 2 , Figure 6 , Figure 9 and Figure 10As shown, the first hole group also includes a third oblong hole 212 extending longitudinally along the second direction. When the first plate surface 31 of the connector 3 is connected to the side plate 2 through the third oblong hole 212, the second plate surface 32 is used to connect to the web plate 201 of the column 200 in the first state; please refer to Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the second hole group includes a fourth waist-shaped hole 222 extending longitudinally along the second direction. When the first plate surface 31 of the connector 3 is connected to the side plate 2 through the fourth waist-shaped hole 222, the second plate surface 32 is used to connect the wing plate 202 of the column 200 in the second state.

[0046] By setting the first and second hole groups in this way, multiple connectors 3 can be connected to the web 201 and wing 202 of the column 200 respectively. The column 200 can switch between the first and second states and achieve a more stable connection between the column 200 and the side plate 2.

[0047] Please refer to Figures 1 to 4 The second plate surface 32 of the upper connector 3 and the second plate surface 32 of the lower connector 3 are respectively used to attach to the opposite sides of the web plate 201 of the column 200, and the second plate surface 32 of the left connector 3 and the second plate surface 32 of the right connector 3 are respectively used to attach to the two wing plates 202 of the column 200. At this time, the column 200 is installed on the side plate 2 of the quick-lock tooling fixture 100 of this utility model in the first state; please refer to Figures 5 to 8 The second plate surface 32 of the upper connector 3 and the second plate surface 32 of the lower connector 3 are respectively used to attach to the two wing plates 202 of the column 200, and the second plate surface 32 of the left connector 3 and the second plate surface 32 of the right connector 3 are respectively used to attach to the opposite sides of the web plate 201 of the column 200. At this time, the column 200 is installed on the side plate 2 of the quick-lock tooling fixture 100 of this utility model in the second state. That is to say, when the column 200 is switched between the first state and the second state, the corresponding connection relationship between the connector 3 and the waist-shaped hole 20 needs to be adjusted accordingly.

[0048] Please refer to Figures 1 to 10As shown, the first hole group includes four first oblong holes 211 and two third oblong holes 212. The four first oblong holes 211 are symmetrically arranged along the first axis and the second axis, and the two third oblong holes 212 are symmetrically arranged along the first axis. The second hole group includes two second oblong holes 221 and four fourth oblong holes 222. The two second oblong holes 221 are symmetrically arranged along the second axis, and the four fourth oblong holes 222 are symmetrically arranged along the first axis and the second axis. The first axis is perpendicular to the second axis. That is, the number of oblong holes 20 in the first hole group is equal to the number of oblong holes 20 in the second hole group, and both are six, for a total of twelve oblong holes 20. These twelve oblong holes 20 are symmetrically arranged with respect to both the first and second axes.

[0049] Specifically, the first axis LL is parallel to the first direction and is the central axis of the second oblong hole 221, and the second axis NN is parallel to the second direction and is the central axis of the third oblong hole 212. The oblong holes 20 are arranged in this way to ensure that when the column 200 is switched between a horizontal and a vertical state, it is easy to adjust the corresponding connection relationship between the four connectors 3 and the twelve oblong holes 20.

[0050] In this embodiment, column 200 is an H-beam. (Reference) Figure 1 and Figure 5 As shown, both the first-state and second-state pillars 200 are horizontally placed, and the first-state pillar 200 is obtained by rotating it 90 degrees around its central axis. Furthermore, the first hole group is used to connect the first-state pillar 200, and the second hole group is used to connect the second-state pillar 200. Therefore, if the first hole group is rotated 90 degrees around the central axis of the pillar 200, its hole arrangement can completely coincide with that of the second hole group.

[0051] The quick-lock tooling fixture 100 of this utility model also includes a plurality of fasteners 4. The first plate 31 is connected to the side plate 2 by the fasteners 4, and the second plate 32 is connected to the column 200 by the fasteners 4.

[0052] The fastener 4 and the connector 3 work together to secure the column 200 to the side plate 2, thereby improving the connection strength between the column 200 and the side plate 2.

[0053] Please refer to Figures 1 to 12As shown, the connector 3 includes a first connector 301 and a second connector 302. The first connector 301 is used to connect the web 201 of the column 200, and the second connector 302 is used to connect the wing 202 of the column 200. The first connector 301 and the second connector 302 are positioned at a 90-degree angle on the side plate 2. This is a modified embodiment, where the column 200 is an H-beam and only one side of the web 201 and one of the wing 202 are positioned and installed on the side plate 2 by a connector 3, while the other side of the web 201 and the other wing 202 are not connected or positioned. In this case, the column 200 can be installed, and the process is reduced to a certain extent, lowering the cost.

[0054] It should also be noted that, please refer to Figure 2 , Figure 6 , Figure 11 and Figure 12 As shown, the first plate surface 31 on the first connector 301 and the first plate surface 31 on the second connector 302 are both provided with first round holes 3001 for fasteners 4 to pass through. When the column 200 is connected to the side plate 2 in the first state, the first round hole 3001 on the first connector 301 is used to correspond to the third waist-shaped hole 212 for a portion of the fasteners 4 to be installed; the first round holes 3001 on the second connector 302 are arranged in two rows for corresponding to the first waist-shaped hole 211 for another portion of the fasteners 4 to be installed; when the column 200 is connected to the side plate 2 in the second state, the first round hole 3001 on the first connector 301 is used to correspond to the second waist-shaped hole 221 for a portion of the fasteners 4 to be installed; the first round hole 3001 on the second connector 302 is used to correspond to the fourth waist-shaped hole 222 for another portion of the fasteners 4 to be installed.

[0055] Please refer to Figure 11 and Figure 12As shown, the first connecting member 301 has n first circular holes 3001 arranged in a row, while the second connecting member 302 has 2n first circular holes 3001 arranged in two rows. This is to accommodate the width requirements of the first connecting member 301 and the second connecting member 302. Because the width of the first connecting member 301 is smaller than the width of the second connecting member 302, the first circular holes 3001 on the first connecting member 301 are arranged in one row, while the first circular holes 3001 on the second connecting member 302 are arranged in two rows. Of course, the second plate surface 32 on the first connecting member 301 and the second plate surface 32 on the second connecting member 302 are both provided with second circular holes 3002 for the fastener 4 to pass through. Compared to the first circular hole 3001, which has n holes arranged in a row, the second circular holes 3002 on the first connector 301 and the second circular holes 3002 on the second connector 302 both have 2n holes arranged in two rows. The reason for this difference is that the second circular holes 3002 are used to fix the column 200, and the column 200 is relatively heavy, so they are both arranged in two rows.

[0056] Of course, in the specific implementation method, please refer to Figures 1 to 12 As shown, the connector 3 also includes a third connector 303 and a fourth connector 304. The first connector 301 and the third connector 303 are used to connect the opposite sides of the web 201 of the column 200, and the second connector 302 and the fourth connector 304 are used to connect the two wing plates 202 at opposite ends of the column 200.

[0057] In this embodiment, the first connector 301 and the second connector 302 are connected at a 90-degree angle on the side plate 2, and the third connector 303 and the fourth connector 304 are also connected at a 90-degree angle on the side plate 2. The first connector 301 and the third connector 303 are arranged opposite each other, and the second connector 302 and the fourth connector 304 are arranged opposite each other. With this arrangement, both sides of the web plate 201 and the two wing plates 202 of the column 200 are all fastened to the side plate 2 through the connectors 3, making the connection between the column 200 and the side plate 2 more stable.

[0058] Please refer to Figures 1 to 12 Special Reference Figure 11 and Figure 12 As shown, the first plate surface 31 on the first connector 301, the first plate surface 31 on the second connector 302, the first plate surface 31 on the third connector 303, and the first plate surface 31 on the fourth connector 304 are all provided with a first round hole 3001 for the fastener 4 to pass through.

[0059] Please continue to refer to Figure 11 and Figure 12As shown, the first circular holes 3001 on the first connector 301 and the third connector 303 are each n and arranged in a row, while the first circular holes 3001 on the second connector 302 and the fourth connector 304 are 2n and arranged in two rows. When the column 200 is connected to the side plate 2 in the first state, the first round holes 3001 on the first connector 301 and the third connector 303 are arranged in a row to correspond to the two third waist-shaped holes 212 for the installation of a portion of the fasteners 4; the first round holes 3001 on the second connector 302 and the fourth connector 304 are arranged in two rows to correspond to the four first waist-shaped holes 211 for the installation of another portion of the fasteners 4; when the column 200 is connected to the side plate 2 in the second state, the first round holes 3001 on the first connector 301 and the third connector 303 are arranged in a row to correspond to the two second waist-shaped holes 221 for the installation of a portion of the fasteners 4; the first round holes 3001 on the second connector 302 and the fourth connector 304 are arranged in two rows to correspond to the four fourth waist-shaped holes 222 for the installation of another portion of the fasteners 4. The second plate surface 32 on the first connector 301, the second plate surface 32 on the second connector 302, the second plate surface 32 on the third connector 303, and the second plate surface 32 on the fourth connector 304 are all provided with second circular holes 3002 for fasteners 4 to pass through. There are 2n such second circular holes 3002 arranged in two rows. It is understood that the detachable connection between the second plate surface 32 and the web plate 201 of the column 200, and between the second plate surface 32 and the wing plate 202 of the column 200, is also achieved through separately provided fasteners 4. However, this part is not the focus and will not be elaborated further.

[0060] In summary, by providing the aforementioned detachable connection method between the connector 3 and the side plate 2, web plate 201, and wing plate 202, the present invention allows the column 200 to be directly fixedly installed on the side plate 2 of the quick-lock fixture 100 without the need to weld the column base plate, thus reducing costs, improving installation efficiency, and enhancing the strength of the column end connection structure. The side plate 2 is provided with multiple oblong holes 20 to adjust the spacing of the connector 3, accommodating columns 200 of different specifications, thus possessing universality. Therefore, compared to the prior art, the present invention improves assembly efficiency, reduces costs, and possesses universality.

[0061] The layout of the waist-shaped holes 20 on the side plate 2 in this utility model is conducive to switching between the horizontal and vertical states of the column 200. It is only necessary to disassemble the connector 3 and fastener 4 to adjust the direction to correspond to the different waist-shaped holes 20, and then reassemble them.

[0062] The quick-lock tooling fixture 100 of this utility model is mainly used for the testing, installation and positioning of H-shaped steel columns 200. In other alternative embodiments, it can also be used for the installation and positioning of C-shaped columns 200.
