Problems solved by technology
The length of the grid plate is up to 800mm, and 26 holes need to be drilled. It is difficult to position and clamp the grid plate during processing, resulting in low machining accuracy of the grid plate, which cannot meet the positional tolerance requirements between multiple holes on the grid plate

Embodiment Construction
[0014] The present invention will be further described below with reference to the drawings and embodiments.
[0015] Such as Figure 1 ~ Figure 3 As shown, the present invention includes a positioning mechanism 1 and three clamping mechanisms 2. The positioning mechanism 1 is arranged on the upper side of the support 31 in the middle of the bed 3 and perpendicular to the longitudinal direction of the bed, and the positioning mechanism 1 is arranged on the support in the middle of the bed 3. The upper side of the seat 31 includes three cushion blocks 11, a first jig base 12 and a second jig base 13. The first jig base 12 and the second jig base 13 are fixed on the top surface of the support 31 in elevation. On the upper side, three spacers 11 are fixed on the top surface of the support 31 at intervals along the longitudinal direction of the support 31, and are located between the first drill mold base 12 and the second drill mold base 13, and the two grid plates 4 arranged side b...

The invention discloses a grid plate double-face multi-shaft drilling jig which comprises a locating mechanism and a plurality of clamping mechanisms. The locating mechanism comprises a plurality of cushion blocks, a first drill jig base and a second drill jig base. The cushion blocks are fixed onto the top face of a support at intervals in the lengthwise direction of the support and located between the first drill jig base and the second drill jig base. Two grid plates are arranged on the cushion blocks side by side in the lengthwise direction in a supported mode, and one side of the grid plate on the inner side abuts against the first drill jig base. The clamping mechanisms comprise L-shaped clamping bases, clamping oil cylinders and connecting rods. The L-shaped clamping bases are fixed inside an inner hole of the support, the clamping oil cylinders are fixed onto the L-shaped clamping bases, the clamping oil cylinders are hinged to the lower ends of the connecting rods, the middle portions of the connecting rods are hinged to the L-shaped clamping bases, the head portions of the clamping oil cylinders are connected with the lower ends of the connecting rods, and the upper ends of the connecting rods stretch out of the top of the support and the bottom of the second drill jig base and abut against the grid plate on the outer side. The grid plate double-face multi-shaft drilling jig is simple in structure, low in cost, accurate in location, and stable and reliable in clamping, and improves the machining precision and the machining efficiency.
Description
Technical field [0001] The invention relates to a special fixture for drilling porous long plate parts, in particular to a special fixture capable of drilling multiple holes on both sides of a grid plate at one time, and belongs to the technical field of fixtures. Background technique [0002] At present, for long plate parts with multiple holes in the longitudinal direction, a radial drilling machine is generally used to drill the holes one by one. This method is time-consuming and labor-intensive, and the processing efficiency is low. In order to improve efficiency, double-sided multi-axis drilling machines are currently used for drilling. The two ends of the bed are symmetrically equipped with power gear boxes, and the multiple drill bits with opposite end faces extend their respective power gears to clamp the grid positioned in the middle of the bed. Multiple holes of the plate are drilled and formed at one time. The grid plate has a length of 800mm, and 26 holes need to be ...
