Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically a drilling device for processing metal parts. Background Technology

[0002] A drilling device is a machine 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. It is generally used in workpiece processing. Drilling devices are used to make holes on the surface of workpieces. For long strip workpieces such as profiles, a workpiece drilling device is required.

[0003] During the operation of a drilling device, vibrations are generated due to the continuous friction between the internal electrodes, the drill bit, and the workpiece. In the existing technology, the drilling device lacks corresponding vibration damping protection measures, which can lead to drill bit deviation and inaccurate hole positions on the workpiece. This also affects the stability of the drilling device and shortens its service life. Furthermore, the drilling angle of the existing drilling device is not easy to adjust, which limits the processing methods of the workpiece and makes it difficult to complete drilling at unconventional angles.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 5 and Figure 6As shown in this embodiment, a drilling device for processing metal parts includes a top seat 1, an adjusting seat 2, and a mounting seat 3. A drilling machine 4 is provided below the mounting seat 3, and the drilling machine 4 is slidably connected to the mounting seat 3. Two sets of cross-distributed supports 25 are provided between the drilling machine 4 and the mounting seat 3. Both sets of supports 25 are rotatably connected to the drilling machine 4 through a rotating shaft. A moving block 26 is rotatably mounted on the end of the support 25 away from the drilling machine 4. The moving block 26 is slidably connected to the mounting seat 3. A damping rod 29 is provided between the moving block 26 and the mounting seat 3. A fourth spring 30 is sleeved on the damping rod 29. The two ends of the damping rod 29 are fixedly connected to the moving block 26 and the mounting seat 3, respectively. The adjusting seat 2 is rotatably connected to the top seat 1 through a first adjusting rod 5, and the mounting seat 3 is rotatably connected to the adjusting seat 2 through a second adjusting rod 6. Two sets of symmetrically distributed ratchet wheels 7 are sleeved on both the 5th and the second adjusting rod 6. The top seat 1 and the adjusting seat 2 are both provided with pawls 8 corresponding to the ratchet wheels 7. The mounting seat 3 is fixedly installed with a locking rod 27. The moving block 26 is slidably sleeved with the locking rod 27. A third spring 28 is sleeved on the locking rod 27. The two ends of the third spring 28 are fixedly connected to the moving block 26 and the mounting seat 3, respectively. During the operation of the drilling machine 4, the continuous friction between the drill bit and the workpiece generates vibration. The vibration force causes the third spring 28 and the fourth spring 30 to be compressed or stretched and deformed. The deformation of the third spring 28 and the fourth spring 30 stores the vibration force. Then, under the action of the damping rod 29, the energy stored in the third spring 28 and the fourth spring 30 is consumed, reducing the impact of the vibration force on the use of the drilling machine 4.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the pawl 8 is engaged with the corresponding ratchet 7. The pawl 8 is rotatably connected to the corresponding top seat 1 or adjusting seat 2 via a rotating rod 9. A first torsion spring 10 is sleeved on the rotating rod 9. The two ends of the first torsion spring 10 are fixedly connected to the pawl 8 and the top seat 1 or adjusting seat 2, respectively. A first gear 11 is sleeved on the rotating rod 9. A first rack 12 corresponding to the first gear 11 is slidably installed in the top seat 1 and the adjusting seat 2. The first rack 12 is engaged with the corresponding first gear 11. A fixing frame 13 is provided in both the adjusting seat 2 and the top seat 1. A slide rod 14 is fixedly installed in both the top seat 1 and the adjusting seat 2. A first spring 15 is sleeved on the slide rod 14. The fixing frame 13 is slidably sleeved with the slide rod 14. The two ends of the first spring 15 are respectively connected to the fixing frame 1. 3. The top seat 1 or adjusting seat 2 are fixedly connected. The two ends of the fixed frame 13 are respectively fixedly connected to a set of first racks 12. Two sets of symmetrically distributed positioning frames 16 are slidably installed in the top seat 1 and the adjusting seat 2. The two sets of positioning frames 16 are respectively set with corresponding fixed frames 13. Positioning rods 17 are fixedly installed on the two sets of positioning frames 16. The two sets of positioning rods 17 are movably engaged with the fixed frame 13. A slider 18 is sleeved on the positioning rod 17. A second spring 19 is sleeved on the positioning rod 17. The two ends of the second spring 19 are respectively fixedly connected to the slider 18 and the top seat 1 or adjusting seat 2. A second rack 20 is fixedly installed on the two sets of positioning frames 16. A handle 21 is fixedly installed on the right second rack 20. The handle 21 passes through the corresponding top seat 1 or adjusting seat 2. The base 2 is slidably connected to the corresponding top base 1 or adjusting base 2. Both the top base 1 and adjusting base 2 have mounting rods 22 rotatably installed inside, corresponding to the two sets of second racks 20. A second gear 23 is sleeved on the mounting rod 22, and the second gear 23 meshes with the two sets of second racks 20 respectively. A second torsion spring 24 is sleeved on the mounting rod 22, and both ends of the second torsion spring 24 are fixedly connected to the second gear 23 and the top base 1 or adjusting base 2 respectively. During the use of the drilling device, the first adjusting rod 5 drives the adjusting base 2 to rotate, and the second adjusting rod 6 drives the mounting base 3 to rotate, thus adjusting the processing angle of the drilling rig 4. When the drilling rig 4 angle is not adjusted, the first adjusting rod 5 and the second adjusting rod 6 are limited by the two sets of ratchet 7 and pawl 8. The lever 6 is not rotatable, maintaining the machining angle of the drill rig 4. When it is necessary to rotate the first adjusting lever 5 or the second adjusting lever 6, the fixed frame 13 drives the sliding of the two sets of first racks 12, which, in conjunction with the first gear 11, causes the rotating rod 9 to drive the pawl 8 to deviate, releasing the position restriction of the pawl 8 on the corresponding ratchet 7. Subsequently, the lever 21 drives the sliding of the second rack 20, which, in conjunction with the second gear 23, causes the two sets of positioning frames 16 to drive the positioning rods 17 to move to both sides. After the fixed frame 13 is aligned with the two sets of positioning rods 17, the lever 21 is released to complete the locking and fixing of the two sets of positioning rods 17 on the fixed frame 13, keeping the pawl 8 in a state of deviating from the ratchet 7. The first adjusting lever 5 or the second adjusting lever 6 can be freely rotated to complete the adjustment of the machining angle of the drill rig 4.

[0025] This utility model provides a drilling device for processing metal parts. The specific working principle is as follows: During the operation of the drill rig 4, vibration is generated due to continuous friction between the drill bit and the workpiece. This vibration causes the third spring 28 and the fourth spring 30 to compress or stretch, resulting in deformation. The deformation of the third spring 28 and the fourth spring 30 stores the vibration force. Subsequently, under the action of the damping rod 29, the energy stored in the third spring 28 and the fourth spring 30 is consumed, reducing the impact of the vibration force on the use of the drill rig 4. During the use of the drilling device, the first adjusting rod 5 drives the adjusting seat 2 to rotate, and the second adjusting rod 6 drives the mounting seat 3 to rotate, thus adjusting the processing angle of the drill rig 4. Without adjusting the angle of the drill rig 4, the first adjusting rod 5 drives the adjusting seat 2 to rotate, and the second adjusting rod 6 drives the mounting seat 3 to rotate, thus adjusting the processing angle of the drill rig 4. Without adjusting the angle of the drill rig 4, the first adjusting rod 2 rotates under the limiting action of the two sets of ratchet wheels 7 and pawls 8. The first adjusting rod 5 and the second adjusting rod 6 are not rotatable, maintaining the processing angle of the drill 4. When it is necessary to rotate the first adjusting rod 5 or the second adjusting rod 6, the two sets of first racks 12 are slidable through the fixed frame 13, which, in conjunction with the first gear 11, causes the rotating rod 9 to drive the pawl 8 to deviate, releasing the position limitation of the pawl 8 on the corresponding ratchet 7. Subsequently, the second rack 20 is slidable through the lever 21, which, in conjunction with the second gear 23, causes the two sets of positioning frames 16 to drive the positioning rods 17 to move to both sides. After the fixed frame 13 is aligned with the two sets of positioning rods 17, the lever 21 is released to complete the locking and fixing of the two sets of positioning rods 17 on the fixed frame 13, keeping the pawl 8 in a state of deviating from the ratchet 7. The first adjusting rod 5 or the second adjusting rod 6 can be freely rotated to complete the adjustment of the processing angle of the drill 4.
