In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0044] The present application provides a floating mounting device of a thin plate drilling and boring machine, such as Figures 1 to 12As shown, it comprises a bearing base 1, a bearing base 2 arranged on the bearing base 1, the bearing base 1 is a material placing base matched with the machining equipment, and the bearing base 2 is used for carrying on the bearing base 1 to carry different workpieces.

[0045] Specifically, the bearing base 2 is provided with at least one carrying station 3.

[0046] The carrying station 3 comprises a floating locking unit 4, a limiting fixing unit 5, and a thin plate supporting mechanism 6 arranged between the floating locking unit and the limiting fixing unit.

[0047] The floating locking unit 4 comprises at least three floating locking mechanisms 40 arranged at intervals, the floating locking mechanism 40 comprises a telescopic source 41 capable of horizontally telescopic displacement, a locking seat 42 arranged on the free end of the telescopic source, the locking seat 42 is provided with a locking block 43 capable of pivoting displacement, a torsional spring 44 in transmission connection with the locking block 43, the locking block 43 is provided with a horizontally abutting locking part 431 and a pressing block 432 capable of pivoting displacement, and the bottom of the abutting locking part is provided with two pressing parts 430 arranged at intervals.

[0048] The limiting fixing unit 5 comprises an end position locking block 51 and a side edge locking mechanism 52 arranged opposite to the floating locking unit, the side edge locking mechanism 52 comprises at least one side edge limiting seat 521 and at least one abutting locking part 522, the end position locking block 51 and the side edge limiting seat 521 form a right angle limiting part, and the abutting locking part 522 comprises a power source 5221 and an abutting locking block 5222 capable of lifting displacement in transmission connection with the power source.

[0049] The thin plate supporting mechanism 6 comprises a plurality of thin plate supporting piles 60 arranged at intervals.

[0050] Specific implementation process and principle description:

[0051] When the clamping operation of the elongated thin plate is carried out, the thin plate is first positioned and carried with the right angle limiting part, at this time, the thin plate is pre-positioned and limited, and is respectively positioned and abutted with the end position locking block 51 and the side edge limiting seat 521, and then the abutting locking of the abutting locking part 522 and the clamping locking of the floating locking unit 4 are carried out.

[0052] That is, the power source 5221 is used for pressing down the abutting locking block 5222 to lock one side of the top surface of the thin plate, and the floating locking mechanism 40 of the floating locking unit 4 is used for pushing the locking seat 42 through the telescopic source 41. In the initial state, the torsional spring 44 makes the pressing block 432 at the end in the upwarp state, after the locking block 43 is pushed to abut against the horizontal abutting locking part 431 and the side wall of the thin plate, and with the continuous pushing, the pressing block 432 is deflected, and the two abutting parts 430 are abutted and locked with the top wall of the thin plate.

[0053] The thin plate is stably locked and fixed, and when drilling and boring operations are performed, the thin plate will be subjected to a certain operation force in the vertical direction. The operation force will cause the thin plate to be deformed to a certain height and to bounce. At this time, when the thin plate is deformed downward, the crimping part 430 will be subjected to a certain follow-up change. In the follow-up change state, since one side of the thin plate is straightly positioned and locked, the amount of change is correspondingly floated and matched with the horizontal lamination locking part 431, so as to meet the deformation follow-up matching locking reliability in the thin plate processing process.

[0054] In addition, it should be noted that the bearing base 2 is provided with a crimping support table 22 corresponding to each crimping block 432. The support surface of the crimping support table 22 is located on the same horizontal plane as the support surface of the thin plate support pile 60. In this way, the point crimping of the plurality of crimping blocks 432 is more reliable and stable.

[0055] In one embodiment, the floating locking mechanism 40 includes a displacement adjustment carrier 401 for carrying the telescopic source, and the telescopic source is provided with a linear displacement adjustment on the displacement adjustment carrier. The displacement adjustment carrier is provided with a positioning tooth row 402, and the bottom of the telescopic source is provided with a positioning tooth row for engaging with the positioning tooth row. An interlocking part is provided between the displacement adjustment carrier and the telescopic source.

[0056] Specifically, the telescopic source 41 has a certain telescopic variation range, and the thin plate has a certain width range. The position degree of the telescopic source can be adjusted by the displacement adjustment carrier 401 to meet the matching requirements of thin plates of different specifications. The positioning tooth row 402 and the interlocking part meet the fixed stability requirements of the telescopic source.

[0057] In one embodiment, the bearing base 2 is provided with two groups of center-symmetrically arranged carrying stations 3, and the two carrying stations share a side locking mechanism 52.

[0058] The side locking mechanism 52 includes two crimping locking parts 522 arranged on both sides of a side limiting seat 521. The side limiting seat is provided with two loading grooves 5210 arranged at intervals. The loading grooves are detachably provided with a side locking block having two limiting ends. The crimping locking block has a rotary displacement, and the crimping locking block 5222 has two crimping matching rods corresponding to the carrying stations.

[0059] Specific implementation process and principle description:

[0060] Generally, the thin plate is a pair of workpieces, and when machining, there are multiple workpiece machining with zero point as the reference. The machining parameters and stroke of multiple workpieces with zero point as the reference ensure the uniformity of multiple groups of workpieces.

[0061] In the case, firstly, the center symmetry meets the zero point reference requirement, in addition, the two loading stations 3 share the side locking mechanism 52, which can realize the relative positioning and limiting of the side, and the deformation amount of the two during the machining process is unified, and the relative forming uniformity is guaranteed.

[0062] In one embodiment, the bearing base 2 has an adjusting displacement in the direction of the interval between the sheet support piles on the bearing base 1, and the bearing base 2 is provided with a positioning part 20.

[0063] Specifically, the adjusting displacement of the bearing base 2 is used for zero correction, and the zero point positioning can be realized through the positioning part 20, so that the initial alignment adjustment is more smooth and efficient. Complicated zero alignment adjustment is not required.

[0064] In one embodiment, the bottom of the bearing base 2 is provided with a support positioning platform 7, the support positioning platform 7 is slidingly arranged on the bearing base 1, and the positioning part is arranged on the support positioning platform.

[0065] That is, the support positioning platform 7 can conveniently change the type of the bearing base 2, and easily adjust the position and position locking of the bearing base 2 on the bearing base 1.

[0066] In one embodiment, the telescopic source 41 and the power source 5221 are respectively hydraulic drive sources, the bottom of the bearing base 2 is provided with a pipeline containing groove 21 for loading the pipeline of the hydraulic drive source, and the support positioning platform and the bearing base have a gap.

[0067] That is, the gap protection requirement of the hydraulic pipeline arrangement is met, and the gap also provides a certain space for the hydraulic cylinder.

[0068] In one embodiment, the hydraulic control main machine 8 is included, and the hydraulic control main machine 8 is drivingly connected with any hydraulic drive source. The hydraulic control main machine 8 is connected with a power control box 9, and the power control box is connected with an operation control box 90.

[0069] That is, the hydraulic control and electrical control arrangement are met, and the operation control is realized.

[0070] In one embodiment, the hydraulic control main machine 8 includes a plurality of control pipelines, the floating locking mechanism of the floating locking unit shares one control pipeline, and the pressure locking part of the side locking mechanism shares one control pipeline.

[0071] Specifically, the floating locking unit is synchronously controlled by one control pipeline, so that the hydraulic pressure of the floating locking mechanism remains consistent, and the elastic cooperation of the floating is realized within a certain range, and the hydraulic pressure of the side locking mechanism also remains consistent, which meets the uniformity requirement of multi-point pressure locking.

[0072] Through the above description, it can be found that by cooperating precise hard limit with side floating limit, and having side pressure and top pressure associated floating cooperation, certain drilling and boring hole deformation can be eliminated, so that the qualified rate of thin plate processing is greatly improved. Center-symmetrical thin plate station can be carried, the relative hard limit side and floating side of the thin plate are consistent, and the relative machining forming uniformity is guaranteed. The linkage hydraulic source is adopted to realize overall clamping and loosening control, the clamping efficiency is high, and the overall layout is more compact. The zero positioning adjustment requirement is met, the relative machining position accuracy is reliable and stable, and the initial alignment adjustment is easy.

[0073] The term "comprising" or any other similar word is intended to encompass non-exclusive inclusion, so that a process, method, article or equipment / device including a series of elements includes not only those elements, but also other elements not explicitly listed, or inherent elements of the process, method, article or equipment / device.

[0074] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
