Description

Technical Field

[0001] The present application relates to the field of door and window sliding support detection, and in particular to a durability detection device for aluminum alloy door and window sliding supports. Background Art

[0002] In the process of home decoration, the selection of doors and windows must comply with national standards. The key to the quality of doors and windows lies in the sliding brace installed on them. The function of the sliding brace is to connect the window sash and the window frame, and to enable the window sash to open and close relative to the window frame. In order to ensure the quality of doors and windows, the durability of the sliding brace is usually tested before the doors and windows leave the factory.

[0003] The traditional testing method is to install the sliding support on the mold window, apply push and pull force to the mold window through the push-pull mechanism, thereby simulating the opening and closing of doors and windows, so as to test the durability of doors and windows during the pushing and pulling process; apply pressure to the mold window in the vertical direction through the extrusion mechanism, thereby simulating the doors and windows in the open state, and testing the supporting performance of the sliding support.

[0004] However, since the sizes of sliding supports of doors and windows of different specifications are different, in order to be able to test sliding supports of different specifications, it is usually necessary to install mold windows of different sizes to adapt to the sliding supports of the same size. After replacing mold windows of different sizes, it is usually necessary to adjust the positions of the push-pull mechanism and the extrusion mechanism so that the push-pull mechanism and the extrusion mechanism can be aligned with the mold window, thereby realizing the movement of the push-pull door and window and the extrusion door and window. However, the conventional adjustment method is to adjust the positions of the push-pull mechanism and the extrusion mechanism separately, but this method has low adjustment efficiency. Summary of the invention

[0008] By adopting the above technical solution, after replacing the sliding support of different sizes, the position of the extrusion mechanism is adjusted by the upper adjusting member, and the position of the push-pull mechanism is adjusted by the lower adjusting member, so that the adjusting mechanism and the extrusion mechanism can be adjusted to a suitable position. When it is necessary to adjust the position of the push-pull mechanism and the extrusion mechanism synchronously, the lower adjusting member is adjusted, and the upper adjusting member is driven by the switching member to move, so as to facilitate the synchronous adjustment of the push-pull mechanism and the extrusion mechanism, thereby improving the adjustment efficiency of the detection device. When it is necessary to adjust the push-pull mechanism or the extrusion mechanism separately, the lower adjusting member is disengaged from the upper adjusting member by driving the switching member to move, so as to facilitate the separate adjustment of the extrusion mechanism, and facilitate the extrusion mechanism to detect the sliding supports opened at different angles, thereby achieving the effect of improving the detection accuracy.

[0009] In a specific feasible implementation scheme, the lower adjusting member includes a lower screw rod and a lower driving member, the lower screw rod is installed on the detection frame, the push-pull mechanism is connected to the lower screw rod through the adjustment frame, the lower driving member is installed at one end of the lower screw rod, the switching member is installed at the other end of the lower screw rod, and the switching member is connected to the lower screw rod, and the lower screw rod is connected to the upper adjusting member through a connecting member.

[0010] By adopting the above technical solution, the lower screw is driven to rotate by the lower driving member, so that the lower screw drives the push-pull mechanism to move, thereby facilitating the adjustment of the position of the push-pull mechanism. The lower screw drives the switching member to work, so that the lower adjustment member and the upper adjustment member can work synchronously or independently under the drive of the switching member, so as to adjust the push-pull mechanism and the extrusion mechanism.

And because the switching block 1 and the switching block 2 are arranged in a back-to-back manner, when the switching block 2 is separated from the switching tooth by controlling the switching rod, only when the switching block 1 is connected to the switching tooth, the lower screw can only drive the switching sleeve to rotate in one direction, so that when the push-pull mechanism is adjusted, the extrusion mechanism does not move. However, when the switching block 2 is reconnected with the switching tooth under the action of the switching rod, at this time, different rotation directions of the lower screw can drive the switching sleeve to rotate, thereby realizing the synchronous adjustment of the push-pull mechanism and the extrusion mechanism.

[0013] In a specific possible implementation scheme, the reset member includes a reset plate, a reset spring and a reset column, the reset spring is installed on the side of the switching plate away from the lower screw rod, a switching hole is opened on the side wall of the switching plate near the switching block two, the reset column is installed in the switching hole, and the side wall of the reset column is in conflict with the side wall of the switching block two, and the end of the switching rod close to the reset plate is in conflict with the side wall of the reset plate.

[0014] By adopting the above technical solution, the switch rod is pushed, so that the switch rod pushes the reset plate to move, so that the reset column on the reset plate is separated from the switch block 2, so that the switch block 2 is connected to the switch tooth. At this time, when the lower screw rod is adjusted, the upper adjustment member can be driven to move synchronously, so as to achieve the effect of synchronous adjustment of the push-pull mechanism and the extrusion mechanism. Pull the switch rod to reset the switch rod, so that the reset plate is reset under the action of the reset spring, so that the reset column drives the switch block 2 to move again, so that the switch block 2 is separated from the switch tooth, so that the push-pull mechanism and the extrusion mechanism can adjust their positions independently.

[0015] In a specific feasible implementation scheme, the connecting member includes a connecting rod, a connecting gear one, a connecting gear two and a connecting gear three, the connecting rod is installed on the detection frame, the connecting gears are coaxially installed on the switching sleeve, the connecting gear two is coaxially installed on the connecting rod, the connecting gear one and the connecting gear two are meshed, the connecting gear three is coaxially installed on the connecting rod at one end away from the connecting gear two, and the connecting gear three is connected to the upper adjusting member.

[0016] By adopting the above technical solution, the lower screw drives the switching teeth to rotate through the switching block one and the switching block two, so that the switching teeth drive the switching sleeve to rotate, and the switching sleeve drives the connecting gear two to rotate through the connecting gear one, so that the connecting gear two drives the connecting rod to rotate, thereby realizing the connection rod driving the upper adjusting part through the connecting gear three, thereby facilitating the adjustment of the extrusion mechanism, so as to apply pressure to the upper side wall of the mold window of different sizes, thereby detecting the sliding support.

[0018] By adopting the above technical solution, the upper screw is driven to rotate by the upper driving member, thereby realizing the action of driving the extrusion mechanism to move, so that when testing mold windows of different sizes, the extrusion mechanism can be moved to the corresponding position, and the position of the extrusion mechanism can be fine-tuned through the angle adjustment mechanism.

[0019] In a specific possible implementation manner, a mounting plate is mounted on the adjustment frame, and the push-pull mechanism is mounted on the mounting plate.

[0020] By adopting the above technical solution, the lower screw is driven to rotate, so that the lower screw drives the adjustment frame to move, thereby driving the push-pull mechanism to achieve horizontal position adjustment, thereby facilitating improving the accuracy of the position adjustment of the push-pull mechanism.

[0021] In a specific possible implementation manner, the push-pull mechanism comprises a push-pull cylinder, the push-pull cylinder is mounted on a mounting plate, and a piston rod of the push-pull cylinder is connected to the mold window.

[0022] By adopting the above technical solution, the push-pull mold window is realized by the push-pull cylinder, thereby simulating the opening and closing actions of doors and windows, thereby facilitating the durability testing of the sliding support.

[0024] By adopting the above technical solution, the upper screw drives the slider to move along the upper screw, so that the slider drives the adjustment plate to move, thereby driving the extrusion mechanism installed on the adjustment plate to move.

A detection device 4 and an adjustment device 5 are installed on the detection frame 1, and the detection device 4 includes a push-pull mechanism 41 and an extrusion mechanism 42, the push-pull mechanism 41 is installed on the detection frame 1, and the push-pull mechanism 41 is connected to the side wall of the mold window 3, and the extrusion mechanism 42 is installed on the detection frame 1, and the extrusion mechanism 42 is in contact with the top wall of the mold window 3. The adjustment device 5 is installed on the detection frame 1, and the push-pull mechanism 41 and the extrusion mechanism 42 are both connected to the adjustment device 5.

[0041] Reference Figure 1, by installing the slide support 2 on the detection frame 1, and installing the mold window 3 on the detection frame 1, connecting the mold window 3 to the slide support 2, and pushing and pulling the mold window 3 through the push-pull mechanism 41, so as to simulate the opening and closing of the door and window, so as to detect the durability of the slide support 2. When it is necessary to test the bearing capacity of the slide support 2, the mold window 3 is opened by the push-pull mechanism 41, and then the upper wall of the mold window 3 is pressed by the extrusion mechanism 42, so as to simulate the mold window 3 in the open state, and test the bearing capacity of the slide support 2. After replacing the slide support 2 of different sizes and replacing the door and window of corresponding sizes, the positions of the push-pull mechanism 41 and the extrusion mechanism 42 are adjusted by the adjustment device 5, so that the push-pull mechanism 41 and the extrusion mechanism 42 can adapt to the mold window 3 after the size is changed.

[0042] Reference Figure 2 The adjustment device 5 includes a displacement adjustment mechanism 51 and an angle adjustment mechanism 52. The displacement adjustment mechanism 51 is installed on the detection frame 1, and the push-pull mechanism 41 is connected to the displacement adjustment mechanism 51. The angle adjustment mechanism 52 is installed on the detection frame 1 and is located above the mold window 3. The extrusion mechanism 42 is connected to the angle adjustment mechanism 52, and the angle adjustment mechanism 52 is also connected to the displacement adjustment mechanism 51.

[0043] Reference Figure 2 The positions of the push-pull mechanism 41 and the extrusion mechanism 42 are adjusted by the displacement adjustment mechanism 51, and then the angle of the extrusion mechanism 42 is adjusted by the angle adjustment mechanism 52 to adapt to the mold window 3 with different opening angles.

[0044] Reference Figure 2 The displacement adjustment mechanism 51 includes an upper adjustment member, a lower adjustment member and a switching member. The upper adjustment member is installed at the upper end of the detection frame 1, and the angle adjustment mechanism 52 is connected to the upper adjustment member. The lower adjustment member is installed at the lower end of the detection frame 1, and the push-pull mechanism 41 is connected to the lower adjustment member. The switching member is installed on one side of the detection frame 1, and the switching member is connected to the lower adjustment member.

[0045] Reference Figure 2 The position of the push-pull mechanism 41 is adjusted by the lower adjusting member, and the lower adjusting member and the switching member are linked to drive the connecting member 53 to move, thereby driving the upper adjusting member to move, so that the operator can adjust the squeezing mechanism 42 when adjusting the push-pull mechanism 41. When only the position of the squeezing mechanism 42 needs to be adjusted, the switching member is driven to move, so that the switching member is disconnected from the lower adjusting member, and then the upper adjusting member is driven to move, so as to adjust the squeezing mechanism 42. At this time, the push-pull mechanism 41 does not move.

When it is necessary to adjust the push-pull mechanism 41 and the extrusion mechanism 42 synchronously, the lower screw rod 511 drives the switching member to work when rotating, so that the switching member can drive the upper adjustment member to move through the connecting member 53. When it is necessary to adjust the extrusion mechanism 42 alone, the lower screw rod 511 is separated from the switching member, so that when the upper adjustment member is adjusted, the lower adjustment member does not move.

[0058] Reference Figure 2 By driving the lower screw rod 511 to rotate, the adjustment frame 413 moves along the lower screw rod 511, thereby driving the mounting plate 412 to move in the horizontal direction, thereby adjusting the position of the push-pull mechanism 41 in the horizontal direction.

[0060] Reference Figure 2 The piston rod of the push-pull cylinder 411 is rotatably connected to the side wall of the mold window 3, and the action of opening and closing the mold window 3 is simulated by controlling the extension and retraction of the piston rod of the push-pull cylinder 411.

[0061] Reference Figure 2 The connecting member 53 includes a connecting rod 531, a connecting gear 1 532, a connecting gear 2 533 and a connecting gear 3 534.

The connecting gear 3 534 is coaxially mounted on the upper end of the connecting rod 531, and the connecting gear 3 534 is connected to the upper adjusting member.

[0062] Reference Figure 2 When the switching sleeve 513 rotates under the drive of the lower adjusting member, the switching sleeve 513 drives the connecting gear 1 532 to rotate, thereby driving the connecting gear 2 533 to rotate, so that the connecting gear 2 533 drives the connecting rod 531 to rotate, thereby driving the connecting gear 3 534 to rotate, thereby driving the upper adjusting member to move.

[0063] Reference Figure 2 and Figure 3 The upper adjusting member includes an upper screw rod 5131 and an upper driving member. The upper screw rod 5131 is rotatably mounted on the upper end of the detection frame 1. A sliding rod 5130 is fixedly mounted on the detection frame 1 near the upper screw rod 5131. The axis of the sliding rod 5130 is parallel to the axis of the upper screw rod 5131. A transmission gear 5128 is coaxially mounted on one end of the upper screw rod 5131 near the connecting rod 531. The transmission gear 5128 is meshed with the connecting gear three 534. The upper driving member includes an upper hand wheel 5129, which is coaxially mounted on one end of the upper screw rod 5131 away from the transmission gear 5128. The angle adjustment mechanism 52 is mounted on the upper screw rod 5131.

[0064] Reference Figure 2 and Figure 3 , when the lower screw rod 511 drives the switching sleeve 513 to rotate, the switching sleeve 513 drives the connecting rod 531 to rotate, so that the connecting gear 3 534 on the connecting rod 531 drives the transmission gear 5128 to rotate, thereby driving the upper screw rod 5131 to rotate, thereby adjusting the position of the angle adjustment mechanism 52. When it is necessary to adjust the upper adjustment member separately, the switching member is controlled to move, and then the upper hand wheel 5129 is driven to rotate, so that the upper screw rod 5131 is rotated, thereby adjusting the position of the angle adjustment mechanism 52, and the transmission gear 5128 is driven to rotate by the upper screw rod 5131, thereby driving the connecting gear 3 534 to rotate, so that the connecting gear 3 534 drives the connecting rod 531 to rotate, thereby driving the connecting gear 2 533 to rotate, so that the connecting gear 2 533 drives the connecting gear 1 532 to rotate, thereby driving the switching sleeve 513 to rotate, at this time, the switching sleeve 513 rotates relative to the lower screw rod 511, and the lower screw rod 511 does not rotate.

[0065] Reference Figure 3 The angle adjustment mechanism 52 includes a slider 523, an adjustment plate 521 and an adjustment bolt 522. The slider 523 is slidably connected to the slide bar 5130, and the slider 523 is threadedly connected to the upper screw rod 5131. A rotating shaft is fixedly installed at the axis center of the top wall of the adjustment plate 521, and the adjustment plate 521 is rotatably installed on the bottom wall of the slider 523 through the rotating shaft. The adjustment bolt 522 is threadedly installed on the side wall of the slider 523, and one end of the adjustment bolt 522 located in the slider 523 contacts the side wall of the rotating shaft. The extrusion mechanism 42 is installed on the bottom wall of the adjustment plate 521.

[0066] Reference Figure 3 , by driving the upper screw rod 5131 to rotate, the slider 523 is driven to move along the axis direction of the upper screw rod 5131, thereby driving the adjustment plate 521 to move, so that the adjustment plate 521 drives the extrusion mechanism 42 to move, thereby adjusting the position of the extrusion mechanism 42. When it is necessary to fine-tune the extrusion mechanism 42, the adjustment plate 521 is rotated so that the adjustment plate 521 drives the extrusion mechanism 42 to rotate relative to the mold window 3. When the extrusion mechanism 42 rotates to a suitable angle, the adjustment bolt 522 is tightened to position the adjustment plate 521 at the current angle.

[0067] Reference Figure 3 The extrusion mechanism 42 includes an extrusion cylinder 421, which is fixedly mounted on the bottom wall of the adjustment plate 521 and away from the axis of the adjustment plate 521. The piston rod of the extrusion cylinder 421 extends downward and contacts the top wall of the mold window 3 in the open state.

[0068] The working principle of the embodiment of the present application is as follows: the operator installs the slide support 2 on the detection frame 1, and correspondingly installs the mold window 3 that meets the size of the slide support 2, and drives the lower hand wheel 512 to rotate, thereby driving the lower screw rod 511 to rotate, so that the lower screw rod 511 drives the adjustment frame 413 to move, and adjusts the height of the push-pull mechanism 41, and at the same time, drives the connecting member 53 to move through the switching member, so that the connecting member 53 drives the upper screw rod 5131 to rotate, thereby adjusting the position of the extrusion mechanism 42, and when it is necessary to fine-tune the position of the extrusion mechanism 42, the position of the extrusion mechanism 42 is fine-tuned by rotating the adjustment plate 521, so that the extrusion mechanism 42 is located above the mold window 3. When the extrusion mechanism 42 and the push-pull mechanism 41 are adjusted to the right position, the push-pull mechanism 41 is controlled to work, so that the push-pull mechanism 41 drives the mold window 3 to open and close continuously, thereby testing the durability of the slide support 2. When the bearing capacity of the slide support 2 needs to be tested, the push-pull mechanism 41 is controlled to open the mold window 3 , and the upper wall of the mold window 3 is pressed down by the extrusion mechanism 42 , so as to test the bearing capacity of the slide support 2 .

[0069] When it is necessary to detect the bearing capacity of the sliding support 2 according to the opening angle of the mold window 3, the lower adjusting member and the upper adjusting member are separated by controlling the action of the switching member, the position of the extrusion mechanism 42 is adjusted by adjusting the upper adjusting member, and the position of the extrusion mechanism 42 is fine-tuned by the adjusting plate 521. At this time, while the upper adjusting member is in action, the lower adjusting member does not act.

[0070] The above are 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.
