Abstract
Description
Technical Field
[0001] The utility model relates to the field of detection, and specifically, to a large bracket deformation detection tooling. Background Art
[0002] The large bracket is a casting part with a complex structure and a large difference in wall thickness. During the casting and solidification process, it is prone to deformation due to stress, and the deformed large bracket will affect the use of customers.
[0003] At present, the detection of the large bracket includes the detection of the shape and position of the mounting holes. When the large bracket undergoes slight deformation, it can still pass the detection of the shape and position of the mounting holes, but it cannot meet the use requirements of customers. Therefore, before delivering the large bracket to customers, it is necessary to add deformation detection to the large bracket to avoid the outflow of deformed parts of the large bracket. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a large bracket deformation detection tooling, which can not only detect the shape and position of the mounting holes of the large bracket, but also detect whether the large bracket is deformed.
[0005] To achieve the above purpose, the utility model provides a large bracket deformation detection tooling, which includes: a tooling body and a workpiece bracket for placing the large bracket;
[0006] The workpiece bracket includes a support positioning body, a positioning mechanism and a support mechanism. The positioning mechanism and the support mechanism are arranged on the support positioning body. The positioning mechanism cooperates with the mounting holes of the large bracket, and the support mechanism is used to support the large bracket;
[0007] Limiting mechanisms are arranged on both sides of the tooling body to detect the passability of the large bracket. The limiting mechanisms include limiting slides, which are arranged parallel to the support positioning body. An upper limiting surface, a lower limiting surface and an end limiting surface connecting the upper limiting surface and the lower limiting surface are arranged in the limiting slides, and the upper limiting surface and the lower limiting surface are arranged oppositely.
[0008] Preferably, the tooling body is slidably connected to the workpiece bracket;
[0009] Sliding rails are arranged on the tooling body, and sliders cooperating with the sliding rails are arranged on both sides of the support positioning body.
[0010] Preferably, the sliding rails are arranged in an L shape, and the sliders slide along the bottom of the L-shaped sliding rails.
[0011] Preferably, the limiting mechanisms are detachably connected to the tooling body.
[0012] Preferably, the limiting mechanisms on both sides are arranged oppositely.
[0013] Preferably, the positioning mechanism includes a plurality of positioning holes, and the plurality of positioning holes correspond to the mounting holes of the large bracket one by one.
[0014] Preferably, the supporting mechanism includes a plurality of support frames, and the plurality of support frames lift the large bracket to a height matching the limiting mechanism.
[0015] Preferably, three support frames are provided, and the three support frames are used to detect the flatness of the bottom surface of the large bracket.
[0016] Preferably, the width of the limiting slideway is not less than the width of the to-be-tested end surface of the large bracket.
[0017] According to the above technical solution, the large-bracket deformation detection tooling of the present utility model positions the large bracket in the horizontal direction by placing the large bracket on the workpiece bracket and the positioning mechanism cooperating with the mounting holes of the large bracket. Preferably, by setting the position and shape of the positioning holes to match the mounting holes, the shape and position accuracy of the mounting holes can be detected by the positioning mechanism, that is, the positioning mechanism can realize the shape and position detection of the mounting holes.
[0018] The supporting mechanism supports the large bracket to realize the limitation of the large bracket by the workpiece bracket in the height direction. Therefore, through the cooperation of the supporting mechanism and the positioning mechanism, the position of the large bracket on the workpiece bracket is determined.
[0019] The upper limiting surface and the lower limiting surface of the limiting slideway are arranged oppositely, and are used to detect whether the upper and lower end surfaces of the large bracket are deformed. If the large bracket is deformed, it may cause the large bracket to be distorted. The planes of the upper and lower end surfaces of the distorted large bracket will change in shape and position, resulting in the originally parallel upper and lower end surfaces being distorted or inclined, and thus the thickness of the large bracket passing through will increase. If it is a slight deformation, the amount of this thickness increase will be very small and difficult to detect with the naked eye. Therefore, a limiting slideway needs to be provided to reliably detect whether the large bracket is deformed.
[0020] The distance between the upper limiting surface and the lower limiting surface of the limiting slideway is set to the thickness of the large bracket. Considering the influence of tolerance, after the height of the limiting slideway is set, the passing shape of the large bracket can be verified through the limiting slideway, so as to judge whether the large bracket is deformed. If the large bracket cannot pass through the limiting slideway, it means that the distance between the upper and lower end surfaces of the large bracket exceeds the designed thickness, thus judging that the large bracket is deformed.
[0021] If the large bracket is distorted along the diagonal, it may cause the length of the large bracket to become longer, making the large bracket unusable for subsequent installation. Therefore, the end limiting surface can effectively prevent the large bracket with a length exceeding the reasonable range from passing through the limiting mechanism, thereby realizing the screening of whether the length of the large bracket is qualified.
[0022] Therefore, by setting the limiting slideway, the effective screening of the deformation of the large bracket can be completed.

[0033] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0034] In the present utility model, unless otherwise stated, the orientation words contained in terms such as "both sides, parallel, inner, relative, bottom" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation to the term.
[0035] Refer to Figure 1-2 The described large bracket deformation detection tooling includes: a tooling body 11 and a workpiece bracket, and the workpiece bracket is used to place the large bracket 10;
[0036] The workpiece support includes a support and positioning body 21, a positioning mechanism, and a support mechanism. The positioning mechanism and the support mechanism are provided on the support and positioning body 21. The positioning mechanism cooperates with the mounting holes of the large support 10, and the support mechanism is used to support the large support 10.
[0037] Limit mechanisms are provided on both sides of the tooling body 11. The limit mechanisms detect the passability of the large support 10. The limit mechanisms include limit slides 30. The limit slides 30 are arranged parallel to the support and positioning body 21. An upper limit surface 31, a lower limit surface 32, and an end limit surface 33 connecting the upper limit surface 31 and the lower limit surface 32 are provided in the limit slides 30. The upper limit surface 31 and the lower limit surface 32 are arranged opposite to each other.
[0038] Through the implementation of the above technical solution, when the large support 10 is placed on the workpiece support, the positioning mechanism realizes the positioning of the large support 10 in the horizontal direction by cooperating with the mounting holes of the large support 10. Preferably, by setting the position and shape of the positioning holes to match the mounting holes, the shape and positional tolerance of the mounting holes can be detected by the positioning mechanism, that is, the positioning mechanism can realize the geometric tolerance detection of the mounting holes.
[0039] The support mechanism is used to support the large support 10, which realizes the restriction of the large support 10 by the workpiece support in the height direction. Therefore, through the cooperation of the support mechanism and the positioning mechanism, the position of the large support 10 on the workpiece support is determined.
[0040] The upper limit surface 31 and the lower limit surface 32 of the limit slide 30 are arranged opposite to each other, and are used to detect whether the upper and lower end faces of the large support 10 are deformed. If the large support 10 is deformed, it may cause the large support 10 to be distorted. The planes of the upper and lower end faces of the distorted large support 10 will change in geometric tolerance, resulting in the distortion or inclination of the originally parallel upper and lower end faces, and thus increasing the thickness through which the large support 10 passes. If it is a slight deformation, the amount of this thickness increase will be very small and difficult to detect with the naked eye. Therefore, it is necessary to set the limit slide 30 to reliably detect whether the large support 10 is deformed.
[0041] The distance between the upper limit surface 31 and the lower limit surface 32 of the limit slide 30 is set to the thickness of the large support 10. Considering the influence of tolerance, after the height of the limit slide 30 is set, the passing shape of the large support 10 can be verified through the limit slide 30, so as to judge whether the large support 10 is deformed. If the large support 10 cannot pass through the limit slide 30, it means that the distance between the upper and lower end faces of the large support 10 exceeds the designed thickness, thus judging that the large support 10 is deformed.
[0042] If the large bracket 10 is distorted along the diagonal, it may cause the length of the large bracket 10 to become longer, making the large bracket 10 unusable for subsequent installation. Therefore, the end limiting surface 33 can effectively block the large bracket 10 with a length exceeding the reasonable range from passing through the limiting mechanism, thereby realizing the screening of whether the length of the large bracket 10 is qualified.
[0043] Therefore, by setting the limiting slideway 30, the effective screening of the deformation of the large bracket 10 can be completed.
[0044] In one implementation, the workpiece bracket is slidably connected to the tooling body 11, and the limiting mechanism is fixedly connected to the tooling body 11. By pushing the workpiece bracket to slide on the tooling body 11, the large bracket 10 can be driven to slide on the tooling body 11. During the sliding process of the large bracket 10, the parts extending beyond the workpiece bracket at both ends need to pass through the limiting slideway 30, and the limiting slideway 30 can verify the passability of the large bracket 10.
[0045] In another implementation, the workpiece bracket is fixedly connected to the tooling body 11, and the limiting mechanism is slidably connected to the tooling body 11. After the large bracket 10 is successfully placed on the workpiece bracket, pushing the limiting mechanism can verify the passability of the large bracket 10, thereby judging the deformation condition of the large bracket 10.
[0046] In this implementation, preferably, the tooling body 11 is slidably connected to the workpiece bracket, a slide rail 12 is provided on the tooling body 11, and sliding blocks cooperating with the slide rail 12 are provided on both sides of the support and positioning body 21.
[0047] By slidingly connecting the workpiece bracket and the tooling body 11 through the slide rail 12 and the sliding block, the workpiece bracket can slide along the length direction of the tooling body 11. The limiting mechanism is fixedly connected to the tooling body 11. Then, during the sliding process of the workpiece bracket, the large bracket 10 located thereon will be driven to attempt to pass through the limiting mechanism. If the large bracket 10 cannot pass through the limiting mechanism, it is considered that the deformation amount of the large bracket 10 is unqualified.
[0048] Preferably, both sides of the support and positioning body 21 can cooperate with the slide rail 12, that is, the support and positioning body 21 itself can be used as a sliding block. By pushing the workpiece bracket, the support and positioning body 21 will slide along the slide rail 12.
[0049] In this implementation, preferably, the slide rail 12 is provided in an L shape, and the sliding block slides along the bottom of the L-shaped slide rail 12.
[0050] The sliding rail 12 is set to be L-shaped instead of the common U-shaped, so that the workpiece support can rely on gravity to abut against the bottom of the L-shaped sliding rail 12 and slide along the bottom of the L-shaped sliding rail 12 after being pushed. Through this structural design, the smoothness of the workpiece support running along the sliding rail 12 can be improved, and the jamming of the workpiece support during the sliding process can be avoided.
[0051] In addition, setting the sliding rail 12 to be L-shaped is more convenient for the disassembly and assembly of the workpiece support. When in use, the workpiece support can be aligned with the sliding rail 12 and placed on the tooling body 11. The two sides of the support and positioning body 21 can act as sliders. When it is necessary to slide the workpiece support, push the support and positioning body 21, and the support and positioning body 21 can slide along the sliding rails 12 on both sides.
[0052] In this embodiment, preferably, the limiting mechanism is detachably connected to the tooling body 11.
[0053] In order to make the large bracket deformation detection tooling have better versatility, the tooling body 11 is detachably connected to the limiting mechanism, so that the tooling body 11 can be very conveniently installed with limiting mechanisms of different sizes in order to detect large brackets of different specifications and sizes.
[0054] Preferably, multiple L-shaped sliding rails 12 can also be provided. The multiple L-shaped sliding rails 12 are arranged in a stepped manner on the tooling body 11. The multiple L-shaped sliding rails 12 are used to support the support and positioning bodies 21 of different widths. The support and positioning bodies 21 of different widths are used to support large brackets 10 of different sizes. Therefore, the multiple L-shaped sliding rails 12 can cooperate with limiting mechanisms of different sizes to very conveniently realize the detection of large brackets 10 of different sizes, so that the large bracket deformation detection tooling has versatility for large brackets 10 of different specifications and sizes.
[0055] Using the L-shaped sliding rails 12 arranged in a stepped manner can very conveniently realize the installation and disassembly of the support and positioning bodies 21 of different sizes.
[0056] In this embodiment, preferably, the limiting mechanisms on both sides are arranged oppositely.
[0057] The limiting mechanisms on both sides are arranged oppositely, so that the limiting mechanisms on both sides can simultaneously detect the passability of the large bracket 10. Therefore, by arranging the limiting mechanisms on both sides oppositely, the deformation of the large bracket 10 in the left and right directions can be detected, and the deformation of the large bracket 10 with one end high and one end low can be found.
[0058] The limiting mechanisms on both sides are arranged oppositely, so that the limiting mechanisms on both sides can simultaneously detect the passability of the large bracket 10. At the same time, through the limiting chutes 30 on both sides, it is possible to avoid the influence of the limiting chutes 30 on the position state of the large bracket 10 to the greatest extent, and avoid the situation where the position state of the large bracket 10 changes when passing through the limiting chute 30 on one side, resulting in inaccurate detection results.
[0059] Especially when the structures on both sides of the large bracket 10 are arranged oppositely, detecting the passability of both sides simultaneously can more reliably achieve the deformation detection of the large bracket 10.
[0060] In this embodiment, preferably, the positioning mechanism includes a plurality of positioning holes 23, and the plurality of positioning holes 23 correspond one-to-one with the mounting holes of the large bracket 10.
[0061] The mounting holes of the casting are usually set as circular holes. When positioning the large bracket 10, when only one positioning hole 23 is set to cooperate with the circular mounting hole, the large bracket 10 has the freedom to rotate along the axis of the circular hole. Therefore, at least two positioning holes 23 need to be set to cooperate with the mounting holes to ensure the position of the large bracket 10 in the plane is determined. The cooperation with the action of gravity enables the large bracket 10 to have a definite position on the workpiece bracket.
[0062] After the position of the large bracket 10 on the workpiece bracket is determined, the detection result is more reliable when the limiting chute 30 verifies the passability of the large bracket 10.
[0063] In this embodiment, preferably, the supporting mechanism includes a plurality of supporting frames 24, and the plurality of supporting frames 24 lift the large bracket 10 to a height that matches the limiting mechanism.
[0064] The upper limiting surface 31 and the lower limiting surface 32 cooperate with each other to complete the detection of the deformation of the large bracket 10. Therefore, in order to ensure the reliability of the detection results of the upper limiting surface 31 and the lower limiting surface 32, it is necessary to ensure that after the large bracket 10 is placed on the workpiece bracket, its height is the ideal detection height, so as to avoid the influence of the height position of the large bracket 10 on the detection results.
[0065] Therefore, it is very important to lift the large bracket 10 by a plurality of supporting frames 24. By lifting the large bracket 10 by a plurality of supporting frames 24, the two ends of the large bracket 10 just cooperate with the limiting mechanisms on both sides.
[0066] In this embodiment, preferably, three supporting frames 24 are provided, and the three supporting frames 24 are used to detect the flatness of the bottom surface of the large bracket 10.
[0067] Set the three support frames 24 to the ideal height. If the flatness of the surface lifted by the support frames 24 at the bottom of the large support frame 10 is ideal, after the large support frame 10 is placed on the support frame 24, the three support frames 24 can achieve stable lifting of the large support frame 10, which is manifested as no shaking occurs after the large support frame 10 is placed. In the actual production process, if the large support frame 10 shakes after being placed on the three support frames 24, it means that the flatness of the bottom surface of the large support frame 10 is insufficient, resulting in the plane supported by the three support frames 24 not coinciding with the plane of the bottom of the large support frame 10. Moreover, the greater the shaking of the large support frame 10, the worse the flatness of the bottom surface of the large support frame 10.
[0068] In this embodiment, preferably, the width of the limit slideway 30 is not less than the width of the end face to be measured of the large support frame 10.
[0069] The width of the limit slideway 30 is not less than the width of the end face to be measured of the large support frame 10, so that the end face to be measured of the large support frame 10 can entirely enter the limit slideway 30 and be detected by the limit slideway 30.
[0070] Preferably, if the widths of the upper end face and the lower end face in the end face to be measured of the large support frame 10 are different, according to needs, the widths of the upper limit face 31 and the lower limit face 32 can also be set to be different.
[0071] When there are multiple end faces to be measured on one side of the large support frame 10, among the multiple end faces to be measured, a wider end face to be measured can be selected, and the widths of the upper limit face 31 and the lower limit face 32 can be determined according to the dimensions of the wider end face to be measured.
