Detailed implementation manners

[0031] The following Figures 1-7 is used to explain the present utility model in detail.

[0032] An auxiliary testing device for the deformation amount of a door panel includes a bottom plate 10, and further includes: a plurality of first adjustment devices 20, each of the first adjustment devices 20 is respectively arranged at both ends of the bottom plate 10, each of the first adjustment devices 20 is respectively drivingly connected with a clamping plate 201, and the gap between two adjacent clamping plates 201 at the same end of the bottom plate 10 forms a clamping groove 202, and the clamping plate 201 is controlled to move left and right along the length direction of the bottom plate 10 through the first adjustment device 20; a plurality of second adjustment devices 30, each of the second adjustment devices 30 is arranged in the middle of the bottom plate 10, each of the second adjustment devices 30 is drivingly connected with a cushion plate 40, and the cushion plate 40 is lifted and lowered through the second adjustment device 30. This device improves the detection efficiency, and through the first adjustment device 20, it can flexibly meet the testing requirements of door panels with different lengths, thereby reducing waste of resources and cost expenditure. Specifically, the openings of the clamping grooves 202 at both ends of the bottom plate 10 face each other, and are used to clamp both ends of the door panel 50 to be tested.

[0033] As Figures 1-3 shown, in this embodiment, a plurality of movable grooves 203 are provided at both ends of the bottom plate 10, the clamping plate 201 is slidably arranged in the movable groove 203, the first adjustment device 20 includes a first screw 204 passing through the bottom plate 10, and the first screw 204 is in threaded driving connection with the bottom end of the clamping plate 201. Specifically, by rotating the first screw 204, the clamping plate 201 moves left and right along the length direction of the bottom plate 10; the threaded driving connection structure between the first screw 204 and the bottom end of the clamping plate 201 refers to the threaded driving connection structure between the second screw 304 and the adjusting member 303 described below.

[0034] As Figures 1-6As shown, in this embodiment, the second adjusting device 30 includes a lifting member 301. One side of the lifting member 301 is connected to the backing plate 40, and a guiding slope 3011 is provided on the other side of the lifting member 301. It also includes a sliding groove 302 provided at the bottom of the bottom plate 10. An adjusting member 303 is slidably provided in the sliding groove 302. It further includes a second screw 304 passing through the middle of the bottom plate 10. The second screw 304 is in threaded driving connection with the adjusting member 303. By rotating the second screw 304, the adjusting member 303 abuts against the guiding slope 3011, thereby lifting and lowering the backing plate 40. Specifically, the middle part of the bottom plate 10 is hollowed out, and the backing plate 40 is lapped on the bottom plate 10; in the initial state, there are two positional relationships between the adjusting member 303 and the lifting member 301. One is that the adjusting member 303 is located on the side of the lifting member 301 close to the highest point of the guiding slope 3011 and the adjusting member 303 can abut against the guiding slope 3011, and a limiting member described below is provided at the lowest point of the guiding slope 3011; the other is that the adjusting member 303 is limited between the highest point and the lowest point of the guiding slope 3011 by setting the limiting member described below. Either of the above two is acceptable. This embodiment is the first one; a through hole 305 is provided in the middle of the bottom plate 10 for passing through the second screw 304, and as Figure 6 shown, the position of this through hole 305 is aligned with the sliding groove 302. After the second screw 304 passes through the through hole 305, it is in threaded driving cooperation with the adjusting member 303 in the sliding groove 302; as Figure 5 shown, the positional relationship among the adjusting member 303, the second screw 304, and the lifting member 301 enables the adjusting member 303 to move linearly from the highest point of the guiding slope 3011 to the lowest point or from the lowest point of the guiding slope 3011 to the highest point under the drive of the second screw 304.

[0035] As Figure 4 shown, in this embodiment, a guiding device is provided between the bottom plate 10 and the backing plate 40. The guiding device is provided to limit the backing plate 40 to only rise or fall relative to the bottom plate 10, avoiding the backing plate 40 from toppling and skewing due to the up-and-down abutting relationship between the bottom guiding slope 3011 and the adjusting member 303 only; further, the guiding device includes a limiting groove and a limiting post 101 inserted and adapted to the limiting groove. The limiting groove is provided on both sides of the bottom plate 10, and the limiting post 101 is provided on the side of the backing plate 40 close to the bottom plate 10.

[0036] In this embodiment, a limiting member is provided in the guiding slope 3011 or the sliding groove 302 to prevent the second screw 304 from rotating excessively. Specifically, the limiting member is a limiting plate. If a limiting member is to be provided on the guiding slope 3011, a limiting plate is provided at the lowest point and / or the highest point of the guiding slope 3011; if a limiting member is to be provided in the sliding groove 302, see the following paragraph.

[0037] In this embodiment, a limiting member (not shown in the figure), i.e., a limiting plate, is vertically provided in the sliding groove 302, and the limiting member is aligned with the lowest point and / or the highest point of the guiding slope 3011. Due to the presence of the limiting member in the sliding groove 302, the moving range of the adjusting member 303 is limited.

[0038] In this embodiment, the adjusting member 303 is provided with rollers that abut against the guiding slope 3011. Specifically, the rollers (not shown in the figure) can be provided on the abutting surface of the adjusting member 303 that abuts against the guiding slope 3011, or can be provided on both sides of the adjusting member 303, as long as the rollers can abut against the guiding slope 3011 when the second screw 304 is rotated. The setting of the rollers reduces the friction force during the process of the adjusting member 303 abutting against the guiding slope 3011.

[0039] As Figures 1-3 shown, in this embodiment, both ends of the second screw 304 are provided on the outer sides of the bottom plate 10 near the outside. Specifically, the second screw 304 can be arranged in the same direction as the first screw 204 or in a different direction. If arranged in the same direction, both ends of the second screw 304 are located in the built-in relief grooves of the bottom plate 10. In this embodiment, they are arranged in different directions, so that both ends of the second screw 304 are provided on the outer sides of the bottom plate 10 near the outside, which is convenient for workers to adjust the second screw 304.

[0040] In this embodiment, the materials of the bottom plate 10, the clamping plate 201, and the cushion plate 40 are rigid materials. Specifically, the materials of the bottom plate 10, the clamping plate 201, and the cushion plate 40 are metals or other materials that are not easily deformed.

[0041] Specifically, the length and width of the bottom plate 10 are 2900 mm and 800 mm respectively; the gap between each clamping plate 201 and the door panel 50 to be tested placed in the card slot 202 is 10 - 20 mm, reserving a certain space for the dry shrinkage and wet expansion of the plate, preventing the plate from affecting the deformation direction and deformation amount due to stress creep during the expansion and contraction process; there are 10 card slots 202 at both ends of the device, which can be used to fix both ends of 10 door panels 50 to be tested at the same time, that is, up to 10 door panels can be tested simultaneously; the height of the clamping plate 201 is 300 mm, and the thickness is 23 ± 1 mm; the width of the cushion plate 40 is 300 mm.

[0042] The working principle of an auxiliary test device for the deformation amount of a door panel proposed by the present utility model is as follows:

[0043] First, according to the length of the door panel 50 to be tested, adjust the first adjusting device 20: hold the end of the first screw 204 and rotate the first screw 204. The clamping plate 201 threadedly connected to the first screw 204 moves left and right along the length direction of the bottom plate 10. Adjust both sides of the bottom plate 10 to adjust the clamping plate 201 to adapt to the length of the door panel 50 to be tested;

[0044] Adjust the height of the adjusting pad 40, and then adjust the distance between the door panel 50 to be tested and the bottom plate 10: Hold the end of the second screw rod 304 and rotate the second screw rod 304. The adjusting member 303 threadedly connected to the second screw rod 304 moves along the highest or lowest point direction of the guiding slope 3011. For example, to increase the height of the pad 40, rotate the second screw rod 304 to make the adjusting member 303 move along the lowest point direction of the guiding slope 3011. Due to the existence of the guiding device, the pad 40 can only move linearly up and down relative to the bottom plate 10. At this time, the pad 40 is lifted by the adjusting member 303; if it needs to be lowered after being raised, rotate the second screw rod 304 in the reverse direction.

[0045] After adjustment, the door panel 50 to be tested can enter the subsequent test process, and the auxiliary purpose of this device is achieved.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
