Description

Technical Field

[0001] The present invention relates to the technical field of workpiece-specific detection devices, and in particular to a detection device and a detection method for a crossbeam on a bracket. Background Art

[0002] The bracket body is a supporting platform and a structural member welded from multiple parts. It has many spatial dimensions, and the upper crossbeam body is a more complex workpiece in the bracket, with many dimensions to be tested, which is not easy to detect with conventional measuring tools.

[0003] for Figure 6 The upper crossbeam body shown has a relatively large size, with 10 upper pads and 22 upper frames that need to be inspected. The processing of the upper frame holes is completed after the upper frames have completed the welding of the upper crossbeam. The position and aperture size of the upper frame holes are a major inspection indicator. Manual inspection of the position and aperture of the upper frame holes is time-consuming and laborious. Summary of the invention

[0010] In the above technical solution, the guide cylinder is fixed to the vertical rib via a cylinder support plate, the bottom plate of the cylinder support plate is fixed to the top of the vertical rib via support plate screws, and the guide cylinder is fixed to the side wall plate of the cylinder support plate.

[0011] In the above technical solution, the positioning module includes a positioning block fixed to the end of the positioning frame and two sets of clamping components respectively arranged at the front and rear middle parts of the positioning frame.

[0012] In the above technical solution, each of the clamping assemblies includes a clamping cylinder and two clamping plates driven by the clamping cylinder.

[0013] In the above technical solution, the cross beam detection device on the support further includes a second detection module for detecting an upper pad of the cross beam on the support, and the second detection module includes a plurality of second detection groups corresponding one-to-one to the upper pad.

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Example 1

[0037] A cross beam detection device on a support, comprising a positioning frame, a positioning module for fixing the cross beam on the support to the positioning frame, and a first detection module for detecting an upper frame hole 24 of the cross beam 2 on the support;

[0038] The positioning frame includes a base plate 1 and vertical ribs 26 fixed on the base plate 1, and a plurality of guide cylinders 4 corresponding to the upper frames of the cross beam body on the bracket are fixed on the vertical ribs 26, and a round hole probe 10 is fixed to the front end of the telescopic rod of each guide cylinder 4.

[0039] The guide cylinder 4 is installed on the vertical rib 26 of the positioning frame through the cylinder base, corresponding to the position of the upper frame hole one by one. The detection method includes the following steps: the crossbeam body on the bracket is fixed to the positioning frame by using the positioning module, the guide cylinder 4 is started, and the telescopic rod of the guide cylinder 4 drives the round hole probe 10 to extend to detect the position and aperture size of the upper frame hole 24. In this way, all the upper frame holes can be detected at one time, avoiding the tedious work of manual detection one by one. Twenty-two guide cylinders 7 are provided corresponding to the upper frame 23.

[0040] More preferably, the guide cylinder 4 is fixed to the side wall plate of the cylinder support plate 21 , and the bottom plate of the cylinder support plate 21 is fixed to the top of the vertical rib 26 by the support plate screws 22 .

[0041] Before testing, the workpiece must be accurately positioned and fixed to achieve the purpose of accurate testing. In order to ensure that the crossbeam on the bracket is accurately fixed on the positioning frame, the positioning module includes a positioning block 12 fixed to the end of the positioning frame and two sets of clamping assemblies respectively arranged in the front and rear parts of the positioning frame, and the clamping assembly includes a clamping cylinder 25 and a clamping plate 5. The clamping plate 5 is driven by the clamping cylinder 25 to clamp the side wall of the crossbeam on the bracket. The clamping cylinder 25 is fixed on the base plate 1 and drives the two clamping plates 5 to clamp the two sides of the crossbeam on the bracket. When fixing the crossbeam on the bracket, first place the crossbeam on the bracket on the positioning frame so that one end of its length direction is close to the positioning block 12, start the two sets of clamping assemblies, and the clamping plate 5 clamps the side wall of the length direction of the upper crossbeam.

[0042] Example 2

[0043] In addition to the position and diameter of the upper frame hole, the upper beam body currently needs to inspect several spatial dimensions, including the symmetry of the two sides of the upper pad relative to the central section of the upper beam body after welding and processing. The original inspection method uses conventional measuring tools with auxiliary instruments, and even requires multiple people to cooperate in the measurement. Due to the large number of dimensions to be inspected, the inspection personnel have a high labor intensity.

[0044] In order to detect the symmetry of the two sides of the upper pad, the cross beam detection device on the bracket also includes a second detection module for detecting the upper pad of the cross beam on the bracket. The second detection module includes a centering cylinder 8 fixed on the positioning frame and arranged corresponding to the upper pad. A clamping block 3 is installed on the mounting plates on both sides of each centering cylinder 8, and a detection groove matching the upper pad 13 is formed on the clamping block 3.

[0045] The centering cylinder has good centering performance. The two clamping blocks 3 are respectively mounted on the mounting plates on both sides of the centering cylinder by means of set screws 18. The symmetry of the upper pad is judged by the fit between the detection groove of the clamping block 3 and the side of the upper pad. The entire detection device is provided with 10 centering cylinders 8 corresponding to the upper pad 13, and each centering cylinder 8 is mounted on the bottom plate.

[0046] Furthermore, in order to prevent the clamp block 3 from swinging when the centering cylinder 8 is tested, each clamp block 3 moves under the guidance of a guide assembly, which includes a guide fixing block 7 fixed on a positioning frame, a guide shaft 9 fixedly assembled on the guide fixing block 7, and a sliding bearing 16 fixedly assembled in the clamp block 3, and the sliding bearing 16 is slidably connected to the guide shaft 9. The setting of the guide assembly increases the stability of the movement of the clamp block 3, and the sliding bearing 16 is embedded in the middle of the clamp block 3 through a clamp ring 17, so that the clamp block 3 can move smoothly on the guide shaft 9.

[0047] More specifically, the guide shaft 9 is fixed in the hole of the guide fixing block 7 by a locking nut 14 , and the guide fixing block 7 is fixed to the base plate 1 or the vertical rib 26 by fixing screws 19 .

[0048] In order to prevent the clamping plate 5 from interfering with the adjacent clamping block 3 , the clamping block 3 adjacent to one of the clamping plates 5 is a left L-shaped clamping block 6 , and the clamping block 3 adjacent to the other clamping plate 5 is a right L-shaped clamping block 11 .

[0049] Example 3

[0050] The detection method of the detection device described in Example 2 comprises the following steps:

[0051] Step 1, first place the upper crossbeam of the bracket on the positioning frame, so that one end of the upper crossbeam in the length direction is close to the positioning block 12, and start the two sets of clamping components, and the clamping plate 5 clamps the side wall of the upper crossbeam in the length direction;

[0052] Step 2, the centering cylinder 8 is started, and the symmetry of the upper pad is judged by the fit between the detection groove of the clamp block 3 and the side of the upper pad;

[0053] The guide cylinder 4 is started, and the telescopic rod of the guide cylinder 4 drives the round hole probe 10 to extend to detect the position and aperture size of the upper frame hole 24;

[0054] Step 3: After the inspection is completed, the cylinders are retracted to remove the workpiece, thereby completing the inspection of the workpiece.

[0055] The symmetry of the upper pad, the position and the size of the aperture of the upper frame hole 24 can be carried out simultaneously, and can be carried out front and back.

[0056] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0057] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
