Description

Technical Field

[0001] The utility model belongs to the technical field of hole-making equipment, in particular to a hole-making equipment. Background Art

[0002] Hole-making equipment is mainly used for drilling operations on different types of workpieces. Existing hole-making equipment generally uses radial drills or vertical drills.

[0003] Currently, a Chinese utility model, publication number CN218964852U, discloses a drilling device comprising a drilling device and a circular base, further comprising a fixing plate, a support rod, and a base. The base is provided with a support rod on top. The fixing plate is mounted on the support rod, with a clearance between the fixing plate and the support rod, allowing it to slide up and down along the support rod. The drilling device is secured to the fixing plate by screws, and a stop block is mounted on the support rod. This drilling device accurately controls the feed rate of the drill bit while ensuring the verticality of the hole, reduces the number of verticality drill cup replacements, reduces the wear rate of the drill bit, and extends the service life of the drill bit. Furthermore, the open space facilitates the discharge of metal chips.

[0004] Traditional radial or vertical drilling equipment can only perform single holes. When drilling multiple holes in a component, the drill bit must be moved back and forth to repeatedly position and drill the workpiece. This not only reduces drilling efficiency but also compromises accuracy. While existing multi-axis drilling equipment can process multiple holes simultaneously, the drilling position cannot be adjusted, limiting the drilling process to fixed locations. Furthermore, it's impossible to freely control the rotation of each drill bit, making multi-axis drilling equipment ineffective for drilling individual holes as needed, making it less practical. Utility Model Content

[0005] The purpose of the utility model is to provide a drilling device, which has the advantages of not only being able to process multiple holes simultaneously, but also being able to adjust the drilling position as needed, and each drill bit can be stopped individually to perform independent drilling.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A hole-making device comprises a shell, a motor is installed on the top of the shell, an output shaft is fixedly installed on the output end of the motor, a transmission shaft is rotatably connected inside the shell, a transmission gear is fixedly sleeved on the surfaces of the output shaft and the transmission shaft, a gear chain is meshed on the surface of the transmission gear, a first slide groove is provided at the bottom of the shell, a driven shaft is slidably connected inside the first slide groove, and the surfaces of the driven shaft and the transmission shaft are fixedly sleeved on the surfaces of the driven gears meshing with each other. A second slide groove is provided on one side of the bottom of the shell body, and an adjusting rod is slidably connected to the inside of the second slide groove, and the surface of the adjusting rod is fixedly sleeved with an adjusting gear that meshes with the gear chain; the bottom of the driven shaft is rotatably connected to a connecting cylinder that is slidably connected to the first slide groove, and the internal thread of the connecting cylinder is connected to a threaded rod, and the top and bottom of the threaded rod are provided with a diamond slot, and the bottom of the connecting cylinder is rotatably connected to a drill bit taper shank sleeve, and the top of the drill bit taper shank sleeve and the bottom of the driven shaft are fixedly installed with a diamond-shaped plugging rod that is slidably plugged in the diamond slot.

[0007] With this technical solution, the driven shaft slides within the first chute, and the gear chain is adjusted using an adjustment rod. This allows the motor to drive multiple drill bits through the gear chain to perform multi-hole drilling while also adjusting the drill bits according to the desired hole location, eliminating the need for repeated positioning and improving drilling efficiency. By rotating the threaded rod to engage or disengage the diamond-shaped insert rod with the diamond-shaped slot at the bottom of the driven shaft, the rotation of the drill bit at the bottom of the driven shaft can be controlled. This allows one or more drill bits to be stopped from drilling as needed, allowing the remaining drill bits to continue drilling independently, improving drilling flexibility and facilitating ease of use.

[0008] The utility model is further configured as follows: a connecting plate is rotatably sleeved on the surfaces of the connecting tube and the adjusting rod, and a limiting bolt is threadedly connected to the housing inside the connecting plate.

[0009] By adopting the above technical solution, the connecting plate is fixed to the bottom of the shell by rotating the limiting bolt, so that the connecting cylinder can rotate inside the connecting plate but will not slide inside the first sliding groove.

[0010] The utility model is further configured as follows: the surface of the transmission shaft is rotatably sleeved with a connecting sleeve which is rotatably connected to the top of the driven shaft.

[0011] By adopting the above technical solution, the driven shaft and the transmission shaft can slide uniformly, thereby improving the sliding stability.

[0012] The utility model is further configured as follows: one side of the top of the shell is opened and bolted with an inspection door.

[0013] The adoption of the above technical solution facilitates the inspection and maintenance of parts inside the shell, thereby improving practicality.

[0014] The utility model is further configured as follows: the top and the bottom of the transmission shaft are both rotatably connected to sliders that are slidably connected to the housing, and the transmission shaft rotates inside the housing through the sliders.

[0015] By adopting the above technical solution, the transmission shaft can slide along the driven shaft inside the housing through the slider, and can rotate at the same time.

[0016] The present invention is further configured as follows: the diamond-shaped insertion rod is a polygonal bar-shaped rod with acute angles, and the interior of the diamond-shaped slot is adapted to the surface of the diamond-shaped insertion rod.

[0017] By adopting the above technical solution, the gear chain can be processed into different types of polygons according to actual needs, thereby improving the versatility of the parts.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The driven shaft slides inside the first chute, and the gear chain is adjusted using the adjustment rod. This allows the motor to drive multiple drill bits through the gear chain to perform multi-hole processing, while also adjusting the drill bits according to the required hole positions, eliminating the need for repeated positioning and improving drilling efficiency.

[0020] 2. By rotating the threaded rod to engage or disengage the diamond-shaped insert rod with the diamond-shaped slot at the bottom of the driven shaft, the drill bit at the bottom of the driven shaft can be controlled to rotate and drill holes. This allows one or more drill bits to stop drilling as needed, allowing the remaining drill bits to drill independently, increasing the flexibility of drilling and facilitating use.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 、 Figure 2 、 Figure 3 A drilling device includes a housing 1. A motor 2 is mounted on the top of the housing 1. An output shaft 3 is fixedly mounted on the output end of the motor 2. A transmission shaft 4 is rotatably connected to the interior of the housing 1. A transmission gear 5 is fixedly mounted on the surfaces of the output shaft 3 and the transmission shaft 4. A gear chain 6 meshes with the surface of the transmission gear 5. A first chute 8 is defined at the bottom of the housing 1. A driven shaft 7 is slidably connected to the interior of the first chute 8. A driven gear 9 is fixedly mounted on the surfaces of the driven shaft 7 and the transmission shaft 4. A second chute 12 is defined on one side of the bottom of the housing 1. An adjustment rod 10 is slidably connected to the interior of the second chute 12. An adjustment gear 11 meshes with the gear chain 6 and is fixedly mounted on the surface of the adjustment rod 10. The driven shaft 7 slides within the first chute 8, and the gear chain 6 is adjusted by the adjustment rod 10. This allows the motor 2 to drive multiple drill bits through the gear chain 6 to perform multi-hole drilling while also allowing the drill bits to be adjusted according to the required hole locations, eliminating the need for repeated positioning and improving drilling efficiency.

[0029] refer to Figure 2 、 Figure 3 The surface rotation sleeve of the transmission shaft 4 is connected with a connecting sleeve 20 which is rotationally connected to the top of the driven shaft 7. The driven shaft 7 and the transmission shaft 4 can slide uniformly to improve the stability of the sliding.

[0030] refer to Figure 1 One side of the top of the housing 1 is opened and bolted with an inspection door 21. It is convenient to detect and repair the parts inside the housing 1, thereby improving practicality.

[0031] refer to Figure 2 The top and bottom of the transmission shaft 4 are rotatably connected to the slider 22 that is slidably connected to the housing 1, and the transmission shaft 4 rotates inside the housing 1 through the slider 22. The transmission shaft 4 can slide inside the housing 1 following the driven shaft 7 through the slider 22, and can rotate at the same time.

[0032] A brief description of the operating process: By turning on the motor 2 to rotate the output shaft 3, the output shaft 3 and the transmission shaft 4 are meshed via the transmission gear 5 and gear chain 6, causing the output shaft 3 to rotate the multiple transmission shafts 4. The transmission shaft 4 then rotates the driven gear 9, which in turn rotates the driven shaft 7. This allows the multiple drill bits mounted on the bottom of the housing 1 via the driven shaft 7 to rotate synchronously, allowing multi-axis hole-making processing on the workpiece. Simultaneously, by pushing the driven shaft 7 to slide within the first chute 8, the connecting sleeve 20 synchronously drives the transmission shaft 4 to slide, causing the transmission shaft 4 to pull the gear chain 6. Then, by pushing the adjustment rod 10 to slide inside the second slide groove 12, when the driven shaft 7 slides inward, the gear chain 6 will become loose. At this time, the adjustment rod 10 can be slid outward to tighten the loose gear chain 6. Conversely, when the driven shaft 7 slides outward, the gear chain 6 will become tight, resulting in insufficient length. At this time, the adjustment rod 10 can be slid inward to loosen the gear chain 6, so that it has enough length to allow the driven shaft 7 to be pulled outward. The adjustment rod 10 can be engaged with the gear chain 6 using the adjustment gear 11, so that the gear chain 6 can slide freely. Finally, the adjusted driven shaft 7 and the adjustment rod 10 can be fixed.

[0033] Example 2:

[0034] refer to Figure 1 、 Figure 2 、 Figure 4 A device for drilling holes is disclosed. The bottom of the driven shaft 7 is rotatably connected to a connecting cylinder 13 that is slidably connected to the first slide groove 8. A threaded rod 14 is internally threadedly connected to the connecting cylinder 13. The top and bottom of the threaded rod 14 are each provided with a diamond-shaped slot 17. The bottom of the connecting cylinder 13 is rotatably connected to a drill taper sleeve 15. The top of the drill taper sleeve 15 and the bottom of the driven shaft 7 are both fixedly mounted with a diamond-shaped insert rod 16 that slidably engages with the diamond-shaped slot 17. By rotating the threaded rod 14 to engage or disengage the diamond-shaped insert rod 16 with the diamond-shaped slot 17 at the bottom of the driven shaft 7, the drill bit at the bottom of the driven shaft 7 can be controlled to rotate and drill holes. This allows one or more drill bits to be stopped from drilling holes as needed, allowing the remaining drill bits to independently drill holes, improving the flexibility of drilling and facilitating use.

[0035] refer to Figure 2 、 Figure 4 A connecting plate 18 is rotatably sleeved on the surface of the connecting tube 13 and the adjusting rod 10. A limit bolt 19 is threadedly connected to the interior of the connecting plate 18 and is engaged with the housing 1. By rotating the limit bolt 19, the connecting plate 18 is fixed to the bottom of the housing 1, so that the connecting tube 13 can rotate inside the connecting plate 18 but will not slide inside the first chute 8.

[0036] refer to Figure 4 The diamond-shaped rod 16 is a polygonal bar with an acute angle, and the interior of the diamond-shaped slot 17 is adapted to the surface of the diamond-shaped rod 16. The gear chain 6 can be processed into different types of polygons according to actual needs to improve the versatility of parts.

[0037] A brief description of the operating process: The drill bit is installed at the bottom of the drill taper sleeve 15. Rotating the drill taper sleeve 15 then causes the diamond-shaped insert 16 to rotate. This allows the diamond-shaped insert 16 to drive the threaded rod 14 within the connecting tube 13, threadedly engaging the connecting tube 13. This allows the threaded rod 14 to slide upward, connecting the diamond-shaped insert 17 at the top of the threaded rod 14 with the diamond-shaped insert 16 at the bottom of the driven shaft 7. The driven shaft 7, thus leveraging the diamond-shaped insert 16 and diamond-shaped insert 17, can then rotate the connecting tube 13 within the first chute 8, causing the drill bit mounted below the drill taper sleeve 15 to rotate and drill a hole. Simultaneously, when the drill taper sleeve 15 is rotated in the opposite direction to reset the threaded rod 14, the diamond-shaped insert 16 at the bottom of the driven shaft 7 no longer contacts the drive shaft 4. As the driven shaft 7 rotates, it idles within the driven shaft 7, preventing the drill bit from drilling.

[0038] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
