Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. Before the drilling machine is processed, a fixture is needed to clamp the workpiece.

[0003] For example, a Chinese patent discloses a drilling machine fixture for mold processing, patent number: CN215699885U. By turning the handle, the position of the clamp in the load-bearing plate can be adjusted, thereby adjusting the position between the clamp and the fixed plate to clamp molds of different sizes.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: the above device clamps and fixes the workpiece by sliding the clamp, but the clamp has a flat surface. When there is an uneven surface workpiece during drilling, the flat clamp will cause the contact clamping area with the uneven workpiece to be smaller, affecting the clamping stability. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a drilling machine which solves the technical problem that the above-mentioned device clamps and fixes the workpiece by sliding a clamping plate, but the clamping plate has a flat surface. When drilling, there is an uneven surface workpiece, and the flat clamping plate will cause a small contact clamping area with the uneven workpiece, thereby affecting the stability of the clamping.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A drilling machine comprises a drilling machine body, the upper end of the drilling machine body is fixedly connected to a placing table, a threaded rod is threadedly connected to the inside of the placing table, a sliding seat is rotatably connected to the outer surface of the threaded rod, the sliding seat is slidably connected to the upper end of the placing table, a slider is slidably connected to the inside of the sliding seat, two clamping blocks are slidably connected to the inside of the sliding seat, both of the clamping blocks are fitted with the slider, a positioning mechanism is fixedly connected to the upper end of the placing table, the positioning mechanism comprises a round rod, and the round rod is fixedly connected to the upper end of the placing table.

[0017] (III) Beneficial effects

[0018] 1. When clamping the workpiece, the threaded rod is screwed, and the threaded rod is threadedly connected to the placement table. During the process of screwing the threaded rod, the sliding seat is pushed to slide. The sliding seat slides to make the clamping block and the workpiece fit together for clamping and fixing. When the workpiece is an uneven surface, the workpiece first contacts and fits with one clamping block. At this time, the threaded rod is then screwed, and the clamping block pushes the other clamping block to extend outward through the slider. The sliding of the slider makes the two clamping blocks have different extension lengths to adapt to workpieces with uneven surfaces, increase the scope of application and flexibility of the fixture, and make the clamping of uneven workpieces more stable.

[0019] 2. During the processing, cutting fluid, tools, etc. can be placed in the tool box. When the processing is completed or the drilling machine body is in an idle state, the rotating block can be screwed. The rotating block can be rotated ninety degrees to loosen the limit on the baffle cover. At this time, the baffle cover is lifted, and the rotating shaft loses the limit of the limit rod. The tool box can be pulled and rotated to be stored in the drilling machine body. The baffle cover is lowered to reset, which can ensure the stable placement of the tool box when stored. The tool box can be rotated for storage by lifting the baffle cover, which saves the space it occupies and avoids damage to the tool box caused by accidental touch and bump, which is beneficial to improving the flexibility and safety of the tool box.

[0026] The embodiment of the present application provides a drilling machine, which effectively solves the problem of the above-mentioned device clamping and fixing the workpiece by sliding a clamping plate. However, the clamping plate has a flat surface. When drilling, there is an uneven surface workpiece. The flat clamping plate will cause a smaller contact and clamping area with the uneven workpiece, affecting the stability of clamping. When clamping the workpiece, the threaded rod is screwed, and the threaded rod is threadedly connected to the placement table. During the process of screwing the threaded rod, the sliding seat is pushed to slide. The sliding seat slides to make the clamping block and the workpiece fit together for clamping and fixing. When the workpiece is an uneven surface, the workpiece first contacts and fits with one clamping block. At this time, the threaded rod is then screwed. The clamping block pushes the other clamping block to extend outward through the compression of the slider. The sliding of the slider causes the two clamping blocks to have different extension lengths to adapt to the uneven surface of the workpiece, thereby increasing the scope of application and flexibility of the clamp and making the clamping of uneven workpieces more stable.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the above-mentioned device clamps and fixes the workpiece by sliding the clamping plate, but the clamping plate has a flat surface. When drilling, there is an uneven surface workpiece. The flat clamping plate will cause a small contact clamping area with the uneven workpiece, affecting the stability of the clamping. The overall idea is as follows: a drilling machine includes a drilling machine body 11, the upper end of the drilling machine body 11 is fixedly connected to a placing table 12, the placing table 12 is internally threadedly connected to a threaded rod 13, the outer surface of the threaded rod 13 is rotatably connected to a sliding seat 14, the sliding seat 14 is slidably connected to the upper end of the placing table 12, the sliding seat 14 is internally slidably connected to a slider 15, and the sliding seat 14 is internally slidably connected to two clamping blocks 16. Both clamping blocks 16 are fitted with the slider 15. When clamping the workpiece, the threaded rod 13 is screwed. The threaded rod 13 is threadedly connected to the placement table 12. During the screwing process of the threaded rod 13, the sliding seat 14 is pushed to slide. The sliding seat 14 slides to make the clamping blocks 16 fit the workpiece for clamping and fixing. When the workpiece is an uneven surface, the workpiece first contacts and fits with one clamping block 16. At this time, the threaded rod 13 is then screwed. The clamping block 16 pushes the other clamping block 16 to extend outward through the slider 15. The sliding of the slider 15 makes the two clamping blocks 16 have different extension lengths to adapt to workpieces with uneven surfaces, increase the application range and flexibility of the fixture, and make the clamping of uneven workpieces more stable.

[0029] A positioning mechanism is fixedly connected to the upper end of the placement table 12, and the positioning mechanism includes a round rod 17, which is fixedly connected to the upper end of the placement table 12, a positioning rod 18 is fixedly connected inside the sliding seat 14, a guide groove 19 is opened inside the slider 15, and the positioning rod 18 is sleeved inside the guide groove 19, and a rotating shaft 21 is rotatably connected inside the drilling machine body 11, and a tool box 22 is sleeved on the outer surface of the rotating shaft 21. When the workpiece is placed and clamped, the round rod 17 installed on the placement table 12 can be used to limit its two ends, and the sliding trajectory of the slider 15 can be limited by the guide groove 19 during the sliding process, and the smoothness of the sliding is improved. The workpiece to be processed is placed on the placement table 12, and it is clamped and fixed by two sliding clamping blocks 16. After the workpiece is clamped, it is drilled by the drilling machine body 11. During the processing, cutting fluid, tools, etc. can be placed in the tool box 22. The tool box 22 is arranged on one side of the drilling machine body 11 to achieve convenient and stable processing operations.

[0030] A storage groove 23 is provided inside the drilling machine body 11, and the tool box 22 is rotatably connected inside the storage groove 23. A connecting seat 24 is fixedly connected to the upper end of the drilling machine body 11, and a blocking cover 25 is rotatably connected inside the connecting seat 24.

When the drilling machine body 11 is in an idle state, the rotating block 28 can be screwed, and the rotating block 28 can be rotated ninety degrees to loosen the limit on the blocking cover 25. At this time, the blocking cover 25 is lifted, and the rotating shaft 21 loses the limit of the limiting rod 26, and the tool box 22 can be pulled and rotated to be stored in the drilling machine body 11.

[0031] In view of the problems existing in the prior art, the utility model provides a drilling machine. When clamping a workpiece, the threaded rod 13 is screwed, and the threaded rod 13 is threadedly connected to the placement table 12. During the screwing process of the threaded rod 13, the sliding seat 14 is pushed to slide. The sliding seat 14 slides to make the clamping block 16 fit the workpiece to clamp and fix it. When the workpiece is an uneven surface, the workpiece first contacts and fits with one clamping block 16. At this time, the threaded rod 13 is then screwed. The clamping block 16 pushes the other clamping block 16 to extend outward through the slider 15. The sliding of the slider 15 makes the two clamping blocks 16 have different extension lengths to adapt to workpieces with uneven surfaces, thereby increasing the application range and flexibility of the clamp and making the clamping of uneven workpieces more stable.

[0032] Working principle:

[0033] The first step is to place the workpiece to be processed on the placement table 12, and clamp it and fix it with two sliding clamping blocks 16. After the workpiece is clamped, it is drilled by the drilling machine body 11. During the processing, cutting fluid, tools, etc. can be placed in the tool box 22. The tool box 22 is arranged on one side of the drilling machine body 11 to achieve convenient and stable processing operations. When clamping the workpiece, the threaded rod 13 is screwed, and the threaded rod 13 is threadedly connected to the placement table 12. During the screwing of the threaded rod 13, the sliding seat 14 is pushed to slide. The sliding seat 14 slides to make the clamping block 16 and the workpiece fit together for clamping and fixing. When the workpiece is an uneven surface, the workpiece first contacts and fits with one clamping block 16. At this time, the threaded rod 13 is then screwed. The clamping block 16 pushes the other clamping block 16 to extend outward through the slider 15. The sliding of the slider 15 makes the two clamping blocks 16 have different extension lengths to adapt to workpieces with uneven surfaces, increase the scope of application and flexibility of the fixture, and make the clamping of uneven workpieces more stable.

[0034] In the second step, when the workpiece is placed and clamped, its two ends can be limited by the round rod 17 installed on the placement table 12. During the sliding process of the slider 15, its sliding trajectory is limited by the guide groove 19, and the smoothness of the sliding is improved. During the processing, cutting fluid, tools, etc. can be placed in the tool box 22. When the processing is completed or the drilling machine body 11 is in an idle state, the rotating block 28 can be screwed, and the rotating block 28 can be rotated ninety degrees to loosen the limit on the baffle cover 25. At this time, the baffle cover 25 is lifted, and the rotating shaft 21 loses the limit of the limit rod 26, so the tool box 22 can be pulled and rotated and stored in the drilling machine body 11. The baffle cover 25 is lowered and reset, which can ensure the stable placement of the tool box 22 when it is stored. By lifting the baffle cover 25, the tool box 22 can be rotated for storage, saving its occupied space and avoiding damage to the tool box 22 caused by accidental touch and bump, which is beneficial to improving the flexibility and safety of the tool box 22.
