[0025] The following will be further described in detail with reference to the attached Figures 1-4 drawings, an embodiment of a positioning die for drilling a plate of the present invention.

[0027] A positioning mold for plate drilling, comprising a base 1, a jig 2 fixed on the base 1, and a calibration component 3 linked to the jig 2, a positioning hole 11 is opened on the base 1 at the position of the drill bit of the drilling equipment; the jig 2 is used to position and clamp the plate 7 to be drilled, and a plurality of jigs 2 are provided, and the plurality of jigs 2 are arranged around the base 1 on the edge of the base 1; the calibration component 3 is used to adjust the position of the plate 7 to be drilled, the calibration component 3 comprises a calibration plate 31, a bearing connection seat 32, a connecting rod 33 and a driving cylinder 34, a calibration roller 35 is provided on the calibration plate 31, and a calibration roller 36 is provided at one end of the calibration roller 35 connected to the plate 7 to be drilled; the calibration roller 36 abuts against one side of the plate 7 to be drilled, and adjusts the position of the plate 7 to be drilled by rotation; one end of the bearing connection seat 32 is rotationally connected to the calibration plate 31, and the other end is rotationally connected to the connecting rod 33; the connecting rod 33 is transmission-connected to the output end of the driving cylinder 34.

[0028] Specifically, Figure 1 and Figure 4 As shown, since the plate 7 to be drilled for producing the chair seat cushion will be designed as a special-shaped surface according to the ergonomic structure so that it can better fit the sitting posture of the human body, and in the process of producing such a seat cushion, when it is necessary to drill holes on its surface, the plate 7 to be drilled is first placed on the base 1. When the position of the plate with holes fixed on the base 1 is offset or moved due to vibration during processing, the calibration plate 31 drives the calibration roller 36 to rotate and adjust the plate 7 to be drilled according to the hole opening requirements of the plate 7 to be drilled through the calibration roller 35, and automatically adjusts the clamping positioning direction and clamping angle according to the height of the plate 7 to be drilled and the position of the special-shaped surface, and finally completes the fixed clamping under the action of the tooling fixture 2.

[0029] Among them, a mounting bracket 37 is connected to one end of the driving cylinder 34, and the mounting bracket 37 is fixedly connected to the bottom end of the base 1. The mounting bracket 37 can stably install the driving cylinder 34 on the bottom of the base 1, and when the driving cylinder 34 drives the connecting rod 33 to rotate, the connecting rod 33 synchronously drives the bearing connecting seat 32 to rotate, thereby controlling the calibration action of the calibration plate 31.

[0030] In this embodiment, if Figure 2 , 3 As shown, the jig 2 is equidistantly arranged between two adjacent calibration components 3, and the jig 2 includes a limit plate 21, a heightening block 22 and a clamping cylinder 23 (not shown in the figure), one end of the limit plate 21 is connected to a transmission shaft 24, and the transmission shaft 24 is transmission-connected to the output end of the clamping cylinder 23 (not shown in the figure); the heightening block 22 is fixed on the base 1, and the heightening block 22 is arranged directly below the limit plate 21.

[0031] Specifically, a plurality of elevation blocks 22 are provided on the elevation block 22, and the plurality of elevation blocks 22 are stacked on top of each other in the vertical direction; the limit block 211 on one side of the limit plate 21 can cooperate with the elevation block 22 to quickly position the to-be-drilled plate 7. At the same time, the pressing block on the base 1 presses and limits the to-be-drilled plate 7 to firmly fix it; at the same time, a fastening bolt 212 for adjusting the clamping force according to the size of the plate is provided on the limit plate 21, and one end of the fastening bolt 212 passes through the limit plate 21 and is fixedly connected to the to-be-drilled plate 7.

[0032] In this embodiment, the stop block 5 has an L-shaped structure, and an adjusting screw 6 is provided on the stop block 5. The adjusting screw 6 is used to finely adjust the height of the limit plate 21 to adapt to plates of different thicknesses.

[0033] Specifically, the function of the stop block 5 is to further clamp and position the to-be-drilled plate 7. The structure of the stop block 5 is used in cooperation with the adjusting screw 6 to limit the movement of the to-be-drilled plate 7 in the longitudinal direction, so that it can be stably fixed on the base 1, thus facilitating the drilling operation. At the same time, the adjusting screw 6 on the stop block 5 can be adjusted according to the thickness of the to-be-drilled plate 7 to expand its scope of application.

[0034] In this embodiment, a positioning pin 4 for determining the position of the to-be-drilled plate 7 is inserted into the positioning hole 11. The number of positioning pins 4 is at least two, and the positioning pins 4 are evenly distributed on the base 1.

[0035] Specifically, when installing the base 1, a positioning hole 11 for positioning with the drilling equipment is opened on the base 1, and a positioning pin 4 is inserted into the positioning hole 11. The base 1 is fixed to the drilling equipment by using the positioning pin 4, thereby completing the positioning of the base 1. At the same time, the other end of the positioning pin 4 is also fixed to the to-be-drilled plate 7, which is used to make the positions of the positioning pin 4, the to-be-drilled plate 7, and the drill bit on the same axis, facilitating subsequent drilling processing.

[0036] It should be noted that, to further improve the drilling accuracy of the drilling equipment, a guide post can also be provided on the positioning hole 11. The guide post is vertically fixed on the base 1 and corresponds to the drill bit. The guide post is used to guide the drill bit during the drilling process to ensure the perpendicularity and position accuracy of the drilling.

[0037] Embodiment Two

[0038] The difference between this embodiment and the first embodiment is that when drilling the flat seat cushion, since it is easy to drill the plate 7 to be drilled with a flat structure, an installation groove 12 for placing the plate 7 to be drilled can be opened on the base 1. Among them, the shape and size of the installation groove 12 are adapted to the plate 7 to be drilled, and it can be positioned and clamped by the tooling fixture 2. Therefore, the calibration component 3 is not required. The installation groove 12 is used to fix and limit the periphery of the flat plate 7 to be drilled. At the same time, the clamping cylinders 23 on both sides (not shown in the figure) are used to drive the limiting plate 21, so that the limiting block 211 presses against the top of the plate 7 to be drilled, and the fixed positioning can be completed.

[0039] The working principle of this embodiment:

[0040] When positioning and fixing the plate 7 to be drilled, first place the plate 7 to be drilled on the positioning die of the drilling equipment, and then the calibration component 3 will adjust the clamping part according to its structure to facilitate the quick clamping and fixing of the plate 7 to be drilled. At the same time, the tooling fixture 2 is used to further clamp and position the plate 7 to be drilled to avoid deviation during the processing. The limiting plate 21 and the padding block 22 are used to fix and position the plate, so as to achieve the accurate positioning and fixing of the plate, ensuring the high efficiency and high quality of the drilling operation; at the same time, it can also automatically adjust the positioning position according to different plate structures, increase its application range, and improve the work efficiency.

[0041] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same parts are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
