Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to an angle-adjustable drilling device. Background Technology
[0002] Drilling equipment refers to a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or cavity in the target object through rotary cutting or rotary extrusion. In daily life, people usually need to use drilling equipment when processing mechanical parts.
[0003] An existing patent (publication number: CN222359685U) discloses "a drilling device for ferrous metal smelting and rolling products, including a mounting plate. A connecting frame is fixedly connected to the lower end of the mounting plate, a first motor is fixedly connected to one side of the connecting frame, a worm gear is fixedly connected to the output shaft of the first motor, a worm wheel is fixedly connected to the bottom of the mounting plate, a rotating table is fixedly connected to the upper end of the worm wheel, placement plates are fixedly connected to all four sides of the rotating table, vertical plates are symmetrically arranged at the upper end of the placement plates, threaded sleeves are provided inside the vertical plates, threaded rods are threadedly connected inside the threaded sleeves, a bearing is fixedly connected to one side of the threaded rod, and a clamping block is fixedly connected to one side of the bearing. By setting up the first motor, worm gear, and worm wheel, the rotating table and placement plates are driven to rotate, thereby driving the ferrous rolled products to rotate. After drilling one ferrous rolled product, another ferrous rolled product can be rotated to the bottom of the drill bit for drilling, resulting in high drilling efficiency."
[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: Most existing drilling equipment lacks angle adjustment function and can only achieve workpiece repositioning by rotating the entire table. It cannot meet the needs of drilling the same workpiece at multiple angles. When the drilling angle needs to be adjusted individually, the operator needs to adjust the material inside the base plate as a whole. The operation is complicated and prone to errors. This greatly limits the flexibility and applicability of the equipment and makes it difficult to meet the processing needs of drilling at multiple angles.
[0005] Therefore, those skilled in the art have provided an angle-adjustable drilling device to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle-adjustable drilling device. Through a two-way lead screw, slider, clamping plate, spring, and guide rod, it can achieve the positioning and stable clamping of ferrous metal rolled products. The angle of the drilling device can be flexibly adjusted by manually rotating the first worm gear. The angle scale on the connecting column allows the operator to intuitively read the rotation angle. The operation is simple, convenient, and highly accurate, and can meet the drilling needs of different angles.
[0007] To achieve the above objectives, the present invention provides the following technical solution: An angle-adjustable drilling device includes a worktable and a rotary table. Multiple connecting plates are fixedly arranged on the outer surface of the rotary table. Each of the multiple connecting plates is provided with a clamping mechanism. Each of the multiple clamping mechanisms includes a bidirectional lead screw. Two sliders are externally threaded to the bidirectional lead screw. Two springs are fixedly arranged on opposite sides of the two sliders. Two clamping plates are fixedly arranged between the multiple springs in pairs. A screw is threaded to opposite sides of the two sliders. A connecting column is fixedly installed on one side of the workbench. A first worm gear is rotatably installed at the lower end of the connecting column. A first worm wheel is rotatably installed on one side of the connecting column. A connecting frame is fixedly installed on one side of the first worm wheel.
[0008] The technical solution of this utility model is further configured as follows: two guide rods are fixedly provided on opposite sides of the two clamping plates, and multiple springs are respectively sleeved on the outside of the multiple guide rods, and the bidirectional screw is externally rotatably disposed inside the connecting plate.
[0009] The technical solution of this utility model is further configured as follows: the two clamping plates are respectively slidably disposed inside the outside of a plurality of guide rods, and the outside of the plurality of guide rods is engraved with scale lines, and the lower ends of the two sliders are slidably disposed inside the connecting plate.
[0010] The technical solution of this utility model is further configured such that: the first worm is meshed with the first worm wheel, and an angle scale line is engraved on one side of the connecting column.
[0011] The technical solution of this utility model is further configured such that: a telescopic rod is fixedly provided at the upper end of the connecting frame, and a drilling device is fixedly provided at the lower end of the telescopic rod.
[0012] The technical solution of this utility model is further configured as follows: a motor is fixedly installed inside the workbench, a second worm gear is fixedly installed at the output end of the motor, and the second worm gear is externally rotatably installed on one side inside the workbench.
[0013] The technical solution of this utility model is further configured such that: a second worm wheel is rotatably arranged inside the worktable, the upper end of the second worm wheel is fixedly arranged at the lower end of the rotary table, and the second worm wheel is meshed with the second worm.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. The present invention proposes an angle-adjustable drilling device. When it is necessary to adjust the drilling angle, the first worm is rotated. Since the first worm is meshed with the first worm wheel and the first worm wheel is fixedly connected to the connecting frame, the rotation of the first worm will drive the first worm wheel to rotate inside the connecting column and make it rotate around the axis, thus completing the angle adjustment of the drilling device. An angle scale line is provided on one side of the connecting column, which makes it easy for the operator to read the rotation angle intuitively, simplifying the operation process, and at the same time meeting the needs of multi-angle drilling.
[0015] 2. The present invention proposes an angle-adjustable drilling device. When clamping and fixing ferrous metal rolled products, the bidirectional lead screw is rotated to drive the slider to move relative to the workpiece. After the clamping plate contacts the workpiece, the slider continues to move and slides outside the guide rod, compressing the spring. This causes the spring to gradually contract between the clamping plate and the slider, resulting in the clamping plate clamping and fixing the rolled product. If it is necessary to finely adjust the position of the rolled product, the screw on one side of the clamping plate can be rotated to block the movement of the clamping plate, causing the center of the rolled product between the two clamping plates to shift. With the help of the scale lines on the guide rod, the operator can make precise adjustments, which is convenient for subsequent drilling operations. Under the action of the spring force, the clamping plate can automatically adapt to the shape of the workpiece and clamp it evenly, ensuring the stability of the workpiece during drilling and improving the drilling accuracy.

[0018] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example
[0019] Reference Figures 1 to 5 As shown, the present invention provides an angle-adjustable drilling device, including a worktable 1 and a rotary table 2. Multiple connecting plates 3 are fixedly arranged on the outer surface of the rotary table 2. Each of the multiple connecting plates 3 is provided with a clamping mechanism 4. The multiple clamping mechanisms 4 include a bidirectional lead screw 403. Two sliders 401 are externally threaded to the bidirectional lead screw 403. Two springs 404 are fixedly arranged on opposite sides of the two sliders 401. Two clamping plates 402 are fixedly arranged between the multiple springs 404 in pairs. Screws 406 are threadedly connected to opposite sides of the two sliders 401.
[0020] Two guide rods 405 are fixedly installed on opposite sides of the two clamping plates 402. Multiple springs 404 are respectively sleeved on the outside of the multiple guide rods 405. The double-acting screw 403 is rotatably installed inside the connecting plate 3. The two clamping plates 402 are respectively slidably installed on the outside of the multiple guide rods 405. The multiple guide rods 405 are engraved with scale lines. The lower ends of the two sliders 401 are slidably installed inside the connecting plate 3.
[0021] A connecting column 8 is fixedly installed on one side of the workbench 1. A first worm gear 9 is rotatably installed at the lower end of the connecting column 8. A first worm wheel 10 is rotatably installed on one side of the connecting column 8. A connecting frame 6 is fixedly installed on one side of the first worm wheel 10.
[0022] The first worm 9 is meshed with the first worm wheel 10. An angle scale line is engraved on one side of the connecting column 8. A telescopic rod 5 is fixedly installed on the upper end of the connecting frame 6, and a drilling device 7 is fixedly installed on the lower end of the telescopic rod 5.
[0023] With the above structure, when drilling ferrous metal rolled products, the ferrous metal rolled products to be processed are first placed stably on the upper end of the connecting plate 3. Then, the bidirectional lead screw 403 is manually rotated. At this time, the slider 401, which is threadedly connected to the bidirectional lead screw 403, will move relative to the inside of the connecting plate 3. The inner wall of the connecting plate 3 restricts the sliding of the slider 401, ensuring that the slider 401 moves smoothly and stably. As the slider 401 slides, the clamping plate 402 connected to it will move synchronously. When the clamping plate 402 contacts the rolled product, if the bidirectional lead screw 403 is continued to be rotated, the clamping plate 402 will remain stationary, while the slider 401 will slide along the outside of the guide rod 405 and move closer to the clamping plate 402. At the same time, the spring 404 is compressed, causing the spring 404 to gradually contract between the clamping plate 402 and the slider 401. The resulting elastic force makes the clamping plate 402 form a stable clamping and fixing effect on the rolled product.
[0024] In addition, the distance between the two clamping plates 402 can be indirectly adjusted by rotating the screw 406 on one side of the clamping plate 402 so that its end abuts against the side wall of the slider 401 and limiting the displacement of the clamping plate 402. This, combined with the scale lines on the outer surface of the guide rod 405, allows for the offset of the workpiece center. The scale lines on the guide rod 405 provide operators with a precise reference for adjustment, facilitating them to finely adjust the position of the rolled product according to actual needs, thereby ensuring accurate positioning for subsequent drilling operations.
[0025] Subsequently, the telescopic rod 5 and drilling device 7 at the upper end of the connecting frame 6 are activated. The telescopic rod 5 pushes the drilling device 7 downward. The drilling device 7 consists of a drive motor and a drill bit. The drive motor drives the drill bit to rotate at high speed, thereby realizing the drilling process on the clamped ferrous rolled products.
[0026] When the drilling angle needs to be adjusted, the operator only needs to manually rotate the first worm 9 inside the connecting column 8. The outer end of the first worm 9 extends to the outside of the connecting column 8 and is equipped with a non-slip handle. The handle is engraved with non-slip texture. Since the first worm 9 and the first worm wheel 10 mesh with each other and the first worm wheel 10 is fixedly connected to the connecting frame 6, the rotation of the first worm 9 will drive the first worm wheel 10 to rotate inside the connecting column 8, thereby driving the connecting frame 6 to rotate around the axis of the first worm wheel 10, realizing flexible adjustment of the drilling device 7 angle. The angle scale line set on one side of the connecting column 8 allows the operator to intuitively read the rotation angle, making the operation more convenient and precise. The spring 404 is made of high relaxation-resistant alloy spring steel to ensure the elasticity stability after long-term use. In addition, the overall structure is relatively simple and convenient for subsequent maintenance. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0027] Reference Figures 1 to 3As shown, a motor 11 is fixedly installed inside the workbench 1, and a second worm gear 12 is fixedly installed at the output end of the motor 11. The second worm gear 12 is externally rotatably installed on one side inside the workbench 1, and a second worm wheel 13 is rotatably installed inside the workbench 1. The upper end of the second worm wheel 13 is fixedly installed at the lower end of the rotary table 2, and the second worm wheel 13 is meshed with the second worm gear 12.
[0028] With the above structure, after the calendered product is clamped, fixed and positioned, the motor 11 inside the worktable 1 is started. The output end of the motor 11 drives the second worm gear 12 to rotate inside the worktable 1. Since the second worm wheel 13 meshes with the second worm gear 12 and the second worm wheel 13 is fixedly connected to the rotary table 2, the rotation of the second worm gear 12 will drive the second worm wheel 13 to rotate inside the worktable 1, thereby causing the rotary table 2 to drive the connecting plate 3 to rotate on the upper end of the worktable 1. The worm gear transmission has a reverse self-locking characteristic, which can effectively ensure the stability of the position after rotation and avoid position deviation caused by vibration and other factors during drilling. After the connecting plate 3 rotates to be directly below the drilling device 7, the drilling operation can be performed.
[0029] During the drilling process, the connecting plate 3, which does not contain ferrous rolled products, can be fully utilized. Then, other rolled products can be clamped in advance. In this way, after the current rolled product is drilled, it can be quickly switched to the next rolled product to be processed, realizing continuous processing and improving production efficiency.
[0030] Reference Figures 1 to 5 As shown above, when drilling ferrous metal rolled products, the product is first placed on the upper end of the connecting plate 3. Then, the bidirectional lead screw 403 is rotated, causing the slider 401 connected to it to move relative to the inside of the connecting plate 3. The inner wall of the connecting plate 3 can limit the sliding of the slider 401, making its movement stable. The sliding of the slider 401 will drive the clamping plate 402 to move synchronously. When the clamping plate 402 contacts the workpiece, the slider 401 continues to move. At this time, the clamping plate 402 remains stationary, while the inside of the slider 401 will slide outside the guide rod 405 and compress the spring 404, causing it to gradually contract between the clamping plate 402 and the slider 401, thereby clamping and fixing the rolled product with the clamping plate 402. The screw 406 on one side of the clamping plate 402 can also be rotated to block the movement of the clamping plate 402, causing the center of the rolled product between the two clamping plates 402 to shift. The scale lines on the guide rod 405 make it convenient for the operator to make precise adjustments, thus facilitating the drilling of the rolled product.
[0031] Subsequently, the motor 11 inside the workbench 1 is started, causing the second worm gear 12 at its output end to rotate inside the workbench 1. Since the second worm wheel 13 is meshed with the second worm gear 12 and is fixedly connected to the rotary table 2, the rotation of the second worm gear 12 will drive the second worm wheel 13 to rotate inside the workbench 1, and cause the rotary table 2 to drive the connecting plate 3 to rotate at the upper end of the workbench 1. The worm gear has a self-locking characteristic, which can ensure the stability of the position after rotation. When the connecting plate 3 rotates to the lower end of the drilling device 7, the telescopic rod 5 at the upper end of the connecting frame 6 and the drilling device 7 are started. The telescopic rod 5 will push the drilling device 7 to move downward. The drilling device 7 consists of a drive motor and a drill bit. The drive motor will drive the drill bit to rotate, thereby realizing the drilling of ferrous metal rolled products. During drilling, ferrous metal rolled products can be fixed on the connecting plate 3 where no ferrous metal rolled products are placed, so as to realize continuous processing.
[0032] When it is necessary to adjust the drilling angle, the operator manually rotates the first worm 9 inside the connecting column 8. Since the first worm 9 is meshed with the first worm wheel 10 and the first worm wheel 10 is fixedly connected to the connecting frame 6, the rotation of the first worm 9 will drive the first worm wheel 10 to rotate inside the connecting column 8. The rotation of the first worm wheel 10 will drive the connecting frame 6 to rotate around the axis, thereby adjusting the angle of the drilling device 7. The connecting column 8 has an angle scale line on one side, which allows the operator to read the rotation angle intuitively, making operation convenient.
[0033] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the concept of the present utility model are within the protection scope of the present utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present utility model should also be considered within the protection scope of the present utility model.
