[0002] The gantry drilling machine is a high-efficiency, high-precision metalworking machine tool with a gantry structure. This structure allows the worktable and spindle box to move flexibly within the gantry, providing a large machining range, making it particularly suitable for processing large workpieces. Equipped with high-precision linear guide pairs, it not only improves the machine tool's motion rigidity and accuracy but also enhances rapid traverse speed, ensuring high machining efficiency. The gantry drilling machine is highly automated, capable of automatically performing various operations such as drilling, reaming, and tapping according to preset programs, which not only improves production efficiency but also ensures the stability and consistency of machining quality.

[0003] In the present technology, gantry drilling machines are usually equipped with a work platform to support the workpiece. When a heavy metal workpiece is placed on the work platform, it is usually inconvenient to lift and separate it from the work platform because the bottom surface of the metal workpiece is in close contact with the work platform and there are no gripping points on the side of the metal workpiece. Therefore, a gantry deep hole drilling machine is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: when there are no gripping points on the side of a metal workpiece, it is usually inconvenient to lift and separate it from the work platform.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A gantry-type deep hole drilling machine includes a drilling mechanism, and a positioning mechanism is provided below the drilling mechanism;

[0007] The positioning mechanism also includes a base, on which a working platform is provided. Several limiting blocks are fixedly connected to the bottom surface of the working platform. The limiting blocks are aligned with the working platform in the length direction, and the lower ends of each limiting block are slidably connected along the top of the base.

[0008] The work platform has uprights on both sides, with support wheels rotatably connected to the bottom of each upright and a top frame fixedly connected to the top of each upright.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, a gantry-type deep hole drilling machine includes a drilling mechanism 1, with a positioning mechanism 2 located below the drilling mechanism 1. The positioning mechanism 2 also includes a base 201, with a working platform 204 located above the base 201. Several limiting blocks 207 are fixedly connected to the bottom surface of the working platform 204, with the limiting blocks 207 aligned with the length of the working platform 204, and the lower ends of each limiting block 207 slidingly connected along the top of the base 201. Vertical plates 210 are provided on both sides of the working platform 204, with support wheels 211 rotatably connected to the bottom of the vertical plates 210. A top frame 213 is fixedly connected to the top of the vertical plates 210, and an extension plate 217 is slidably connected to the inner wall of the top frame 213. One end of the extension plate 217 extends above the working platform 204 and is fixedly connected to a support frame 218. Lower insertion blocks 219 are fixedly connected to both sides of the bottom surface of the support frame 218. Figure 1 As shown, the support wheel 211 facilitates the movement of the upper plate 210 above the ground, and a certain gap is left between the support frame 218 on the ground and the support block 206 above.

[0027] A clamping plate 220 is slidably connected to the top of the support frame 218. A washer 222 is fixedly connected to one side of the clamping plate 220, and a lead screw 221 is rotatably connected to the other side of the clamping plate 220. The outer wall of the lead screw 221 passes through the support frame 218 and is threadedly connected. Figure 5 As shown, gasket 222 is made of rubber;

[0028] A rack 205 is fixedly connected to the center of the bottom surface of the work platform 204. Slide grooves 208 are provided on both sides of the outer surface of the work platform 204. Both the rack 205 and the slide grooves 208 are aligned with the length of the work platform 204. Several positioning holes 209 are provided at the upper and lower ends of the inner side of the slide grooves 208. Figure 3 As shown, the spacing between adjacent positioning holes 209 is consistent;

[0029] A slider 212 is embedded and fixed on the inner wall of the upright plate 210 near the slide groove 208. A lead screw 214 is threaded onto the middle of the inner side of the slider 212. One end of the lead screw 214 is rotatably connected to a pressing block 215. The pressing block 215 slides along the inner wall of the slider 212. The upper and lower ends of the pressing block 215 are in contact with positioning beads 216. The end of each positioning bead 216 located away from the pressing block 215 protrudes from the surface of the slider 212, and the end of the positioning bead 216 passes through the slider 212 and is inserted into the positioning hole 209. Figure 4 As shown, when the extrusion block 215 moves to the right, neither the upper nor lower surface of the extrusion block 215 contacts the positioning bead 216, so that the positioning bead 216 can retract into the slider 212.

[0030] A motor 202 is fixedly installed at the top center of the base 201. The output shaft of the motor 202 faces upward and is fixedly connected to a gear 203. The side of the gear 203 meshes with a rack 205. Figures 1-2 As shown, the working platform 204 slides relative to the base 201 via the motor 202;

[0031] Several support blocks 206 are fixedly connected to the top surface of the work platform 204. Each support block 206 is equidistant from the short side of the top surface of the work platform 204, and the spacing between adjacent support blocks 206 is the same as the width of the lower insertion block 219. The surfaces of the support blocks 206 abut against the lower insertion block 219. Figure 1 As shown, after the lower insert 219 is inserted into the gap of the support block 206, the support frame 218 cannot move in the width direction of the work platform 204.

[0032] The drilling mechanism 1 includes a gantry support 101, an electric guide block 102 is mounted on the upper end of the gantry support 101, and a drilling rig 103 is mounted on the bottom of the electric guide block 102. Figure 1 As shown, a hydraulic rod is provided between the electric guide block 102 and the drilling rig 103, which can drive the drilling rig 103 to rise and fall.

[0033] The working principle of this utility model:

[0034] The extension plate 217 slides within the top frame 213 to determine the approximate distance between the two support frames 218. After the gap between the lower insert block 219 at the bottom of the support frame 218 and the support block 206 is aligned, the upright plate 210 is pushed to drive the lower insert block 219 to slide into the gap between the support blocks 206. At this time, the movement of the support frame 218 is hindered and it remains relatively fixed to the upright plate 210 and the top frame 213, and the slider 212 slides into the groove 208.

[0035] Next, the workpiece to be processed is placed above the two support frames 218. Then, the second lead screw 221 is rotated to drive the clamping plate 220 closer to the side of the workpiece. The shim 222 abuts against the workpiece to prevent it from shaking. Then, the first lead screw 214 is rotated to press the inside of the slider 212. The first lead screw 214 pushes the pressing block 215 to move towards the positioning bead 216. The top and bottom surfaces of the pressing block 215 gradually push the end of the positioning bead 216 to the surface of the slider 212. Then, the end of the positioning bead 216 abuts against the inside of the positioning hole 209. At this time, the upright plate 210 and the working platform 204 remain relatively fixed.

[0036] When the motor 202 starts, it drives the gear 203 to rotate. The gear 203 pushes the rack 205 and moves the working platform relative to the base 201, which facilitates the positioning of the drilling machine 103 with the machining point on the top surface of the workpiece. After the machining is completed, the lead screw 214 is rotated in the opposite direction, thereby releasing the lock between the vertical plate 210 and the working platform 204. The vertical plate 210 is pushed to separate the workpiece above from the working platform 204, so that it can be lifted and collected from the bottom of the workpiece.

[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
