Technical Field
[0001] This application relates to the field of precision machining technology, and in particular to a position adjustment device and drilling equipment for drilling. Background Technology
[0002] For some workpieces, it is necessary to create three blind holes. Two of the blind holes are parallel to each other, and the third blind hole forms a certain angle with the two blind holes.
[0003] Currently, the workpiece is positioned manually, then multiple clamping components are used to clamp different parts of the workpiece, and a drilling machine is used to create the first blind hole in the workpiece. Next, the multiple clamping components are released from the workpiece, the workpiece is positioned manually again, and the multiple clamping components are used to clamp different parts of the workpiece again, and a drilling machine is used to create the second blind hole. Then, the multiple clamping components are released from the workpiece, the workpiece is positioned manually again, and the multiple clamping components are used to clamp different parts of the workpiece again, and a drilling machine is used to create the third blind hole.
[0004] The existing technical solutions mentioned above have the following drawbacks: when multiple blind holes are generated on the workpiece, the position of the workpiece needs to be adjusted manually multiple times, and the workpiece needs to be pressed and released multiple times, resulting in low blind hole processing efficiency. Summary of the Invention
[0005] To improve the efficiency of blind hole machining, this application provides a drilling position adjustment device and drilling equipment.
[0006] The primary objective of this application is to provide a drilling position adjustment device, which employs the following technical solution: A drilling position adjustment device, comprising: First position adjustment mechanism; The second position adjustment mechanism is installed on the first position adjustment mechanism; An angle adjustment mechanism is mounted on a second position adjustment mechanism, and its top surface is used to support the workpiece; a first position adjustment mechanism is used to drive the second position adjustment mechanism, the angle adjustment mechanism, and the workpiece to move along the X-axis; a second position adjustment mechanism is used to drive the angle adjustment mechanism and the workpiece to move along the Y-axis; and an angle adjustment mechanism is used to drive the workpiece to rotate around the Z-axis. The first limiting mechanism, installed on the angle adjustment mechanism, can contact one side of the workpiece to limit the movement of the workpiece; The second limiting mechanism, installed on the angle adjustment mechanism, can contact one end of the workpiece to limit the movement of the workpiece; The third limiting mechanism, installed on the angle adjustment mechanism, can contact the top surface of the workpiece to limit the movement of the workpiece.
[0007] By adopting the above technical solution, firstly, the workpiece is placed on the top surface of the angle adjustment mechanism. Then, the first limiting mechanism activates, contacting one side of the workpiece. The second limiting mechanism activates, contacting one end of the workpiece. The third limiting mechanism activates, contacting the top surface of the workpiece. Afterward, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a first blind hole on the workpiece. After completing the first blind hole machining, the drilling machine resets. Then, the first position adjustment mechanism drives the second position adjustment mechanism, the angle adjustment mechanism, and the workpiece to move along the X-axis, and the second position adjustment mechanism drives the angle adjustment mechanism and the workpiece to move along the Y-axis. Next, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a second blind hole on the workpiece. After completing the second blind hole machining, the drilling machine resets. Then, the angle adjustment mechanism drives the workpiece to rotate around the Z-axis, the first position adjustment mechanism drives the second position adjustment mechanism, the angle adjustment mechanism, and the workpiece to move along the X-axis, and the second position adjustment mechanism drives the angle adjustment mechanism and the workpiece to move along the Y-axis. Next, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a third blind hole on the workpiece. After completing the machining of the third blind hole, the drilling machine resets. Overall, the first position adjustment mechanism, the second position adjustment mechanism, and the angle adjustment mechanism work together to replace manual adjustment of the workpiece position, improving position adjustment efficiency and accuracy, which in turn helps to improve the efficiency and accuracy of blind hole machining. The first limit mechanism, the second limit mechanism, and the third limit mechanism constrain the workpiece in three orthogonal directions, effectively resisting the multi-directional cutting forces generated during drilling and preventing workpiece movement. This is suitable for limiting irregularly shaped workpieces, ensuring drilling position accuracy and blind hole orientation accuracy. Multiple blind holes can be machined in a single clamping, eliminating the need for multiple clamping and releasing of the workpiece, thus improving blind hole machining efficiency.
[0008] This application further specifies that the angle adjustment mechanism includes: The first rotating shaft is rotatably mounted on the top of the second position adjustment mechanism; The first turntable is fixed to the top of the first rotating shaft and rotates with the first rotating shaft; The driven gear is sleeved on the first rotating shaft; The driving gear has its sidewall meshing with the sidewall of the driven gear; The first rotary driver is fixed to the top of the second position adjustment mechanism. Its output shaft is fixedly connected to the drive gear and is used to drive the drive gear to rotate, thereby driving the driven gear and the first rotating shaft to rotate, and in turn driving the first turntable to rotate. The second rotating shaft is rotatably mounted on the top of the first turntable; The second turntable is fixed to the top of the second rotating shaft and rotates with the second rotating shaft; There are two transmission plates, which are fixed to opposite sides of the second rotating shaft respectively; There are two fixing plates, which are fixed to opposite sides of the top surface of the first turntable. There are two external tubes, both of which are arc-shaped and are fixedly connected at one end to two fixing plates respectively; each external tube has a vent at the end near the fixing plate. There are two inner catheters, both of which are arc-shaped. One end of each inner catheter is inserted into the other end of the two outer catheters, corresponding to each other. The other end of each inner catheter is fixedly connected to the two transmission plates, corresponding to each other. The two inner catheters are connected to the interiors of the two outer catheters, corresponding to each other.
[0009] By employing the above technical solution, during angle adjustment, firstly, the first rotary actuator drives the drive gear to rotate, thereby causing the driven gear, the first rotating shaft, and the first turntable to rotate significantly. This, in turn, causes the second rotating shaft, the second turntable, and the workpiece to rotate significantly, achieving rapid coarse angle adjustment. Then, the air supply is precisely controlled to precisely control the protrusion length of each inner guide tube, which in turn causes the two transmission plates to rotate slightly, thereby causing the second rotating shaft, the second turntable, and the workpiece to rotate slightly, achieving fine angle adjustment. This ensures the positional accuracy and routing accuracy of the third blind hole.
[0010] This application further specifies that: there are two first limiting mechanisms, which can contact the same side of the workpiece; Each first limit mechanism includes: The first linear actuator is fixed to the top of the angle adjustment mechanism; The pressing component is fixedly connected to the output shaft of the first linear driver and can come into contact with the workpiece.
[0011] By adopting the above technical solution, the two first limiting mechanisms limit the workpiece at different positions on the same side, effectively preventing the workpiece from swinging, and are suitable for machining holes in irregularly shaped parts. One of the first limiting mechanisms can contact the first connecting part of the workpiece. When forming the first blind hole, it can prevent the first connecting part from moving away from the drilling machine, ensuring drilling efficiency and drilling effect. The other first limiting mechanism can contact one end of the second connecting part of the workpiece. When forming the second blind hole, it can prevent the second connecting part from moving away from the drilling machine, ensuring drilling efficiency and drilling effect. After the workpiece is placed at the top of the angle adjustment mechanism, the first linear drive is activated, causing the pressing member to move quickly toward the workpiece to quickly contact the first / second connecting part, ensuring limiting efficiency.
[0012] This application further specifies that the pressing element includes: The active plate is fixedly connected to the output shaft of the first linear driver on one side. The driven rod is fixedly connected at one end to the other side of the driving plate; The limiting frame is fixedly connected to the other end of the driven rod on one side, and the other side is an open structure with a clearance cavity inside. The first pressure plate is located on one side of the clearance cavity, and one side can contact the workpiece; The first tightening bolt is rotatably installed on one side of the limiting frame, with one end abutting against the other side of the first pressure plate; The second pressure plate is located on the other side of the clearance cavity, and one side of it can contact the workpiece; The second tightening bolt is rotatably installed on the other side of the limiting frame, with one end abutting against the other side of the second pressure plate; The third pressure plate is located on one side of the clearance cavity, and one side can contact the workpiece. The third tightening bolt is rotatably installed on the other side of the limiting frame, with one end abutting against the other side of the third pressure plate.
[0013] By adopting the above technical solution, the first, second, and third tightening bolts control the positions of the first, second, and third pressure plates, respectively, ensuring that they are tightly fitted to the ends of the first / second connecting parts. Even if the ends of the first / second connecting parts are irregularly shaped, such as curved or sloping surfaces, the reliability of the positioning is still guaranteed. The first, second, and third pressure plates generate clamping force on three sides, dispersing the clamping force and preventing damage to the workpiece from single-point clamping force. Simultaneously, positioning accuracy is ensured.
[0014] This application further specifies that the second limiting mechanism includes: The second linear actuator is fixed to the top of the angle adjustment mechanism; The pressure block is fixedly connected to the output shaft of the second linear driver and can come into contact with the workpiece.
[0015] By adopting the above technical solution, after the workpiece is placed at the top of the angle adjustment mechanism, the second linear driver is activated, causing the pressing block to move rapidly toward the workpiece so as to quickly contact the second connecting part, ensuring the limiting efficiency. When forming the third blind hole, the second limiting mechanism can prevent the workpiece from moving away from the drilling machine, ensuring drilling efficiency and drilling effect.
[0016] This application is further configured such that a limiting groove is formed on the side of the pressing block away from the second linear driver.
[0017] By adopting the above technical solution, on the one hand, the limiting groove helps to improve positioning accuracy; on the other hand, the limiting groove can prevent the workpiece from wobbling slightly, thus ensuring the drilling effect.
[0018] This application further specifies that the third limiting mechanism includes: The support base is fixed to the top of the angle adjustment mechanism; The pressure seat is mounted on the support base and can be moved up and down. The lead screw is vertically mounted and rotatably installed on the support base; The nut is sleeved on the lead screw and fixedly connected to the pressure seat; The second rotary drive is installed on the top of the support base, and its output shaft is fixedly connected to the top of the lead screw. It is used to drive the lead screw to rotate, thereby driving the lead nut and the pressure seat to move up and down.
[0019] By adopting the above technical solution, after the workpiece is placed at the top of the angle adjustment mechanism, the second rotary driver actuates, causing the pressure seat to move downwards rapidly to quickly contact the top surface of the third connecting part, ensuring the limiting efficiency. The third limiting mechanism applies adjustable pressure to the top surface of the third connecting part, effectively suppressing the upward movement of the workpiece and ensuring that no burrs or chipping occurs at the orifice position. By controlling the rotation angle of the second rotary driver, stepless adjustment of the clamping force can be achieved, suitable for clamping workpieces of different hardness, such as plastic parts, aluminum parts, and steel parts.
[0020] This application further specifies that the first position adjustment mechanism includes: substrate; The first linear module is set along the X-axis and fixed to the top of the substrate; The first movable seat is disposed above the substrate, and its bottom end is fixedly connected to the sliding seat of the first linear module.
[0021] This application further specifies that the second position adjustment mechanism includes: The second linear module is set along the Y-axis and fixed to the top of the first movable base; The second movable seat is located above the first movable seat, and its bottom end is fixedly connected to the sliding seat of the second linear module.
[0022] The second objective of this application is to provide a drilling device, which adopts the following technical solution: A drilling apparatus includes a drilling machine and a drilling position adjustment device; the drilling machine is disposed on one side of the drilling position adjustment device and is used to generate a first blind hole, a second blind hole and a third blind hole on a workpiece.
[0023] In summary, the beneficial technical effects of this application are as follows: 1. First, place the workpiece on the top surface of the angle adjustment mechanism. Then, the first limiting mechanism activates, contacting one side of the workpiece. The second limiting mechanism activates, contacting one end of the workpiece. The third limiting mechanism activates, contacting the top surface of the workpiece. Next, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a first blind hole on the workpiece. After completing the first blind hole machining, the drilling machine resets. Then, the first position adjustment mechanism drives the second position adjustment mechanism, the angle adjustment mechanism, and the workpiece to move along the X-axis, and the second position adjustment mechanism drives the angle adjustment mechanism and the workpiece to move along the Y-axis. Next, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a second blind hole on the workpiece. After completing the second blind hole machining, the drilling machine resets. Then, the angle adjustment mechanism drives the workpiece to rotate around the Z-axis, the first position adjustment mechanism drives the second position adjustment mechanism, the angle adjustment mechanism, and the workpiece to move along the X-axis, and the second position adjustment mechanism drives the angle adjustment mechanism and the workpiece to move along the Y-axis. Next, the drill bit of the drilling machine rotates, and the drilling machine moves along its own axis, creating a third blind hole on the workpiece. After completing the machining of the third blind hole, the drilling machine resets. Overall, the first position adjustment mechanism, the second position adjustment mechanism, and the angle adjustment mechanism work together to replace manual adjustment of the workpiece position, improving position adjustment efficiency and accuracy, which in turn helps to improve the efficiency and accuracy of blind hole machining. The first limit mechanism, the second limit mechanism, and the third limit mechanism constrain the workpiece in three orthogonal directions, effectively resisting the multi-directional cutting forces generated during drilling and preventing workpiece movement. This is suitable for limiting irregularly shaped workpieces, ensuring drilling position accuracy and blind hole orientation accuracy. Multiple blind holes can be machined in a single clamping, eliminating the need for multiple clamping and releasing of the workpiece, thus improving blind hole machining efficiency.
[0024] 2. During angle adjustment, firstly, the first rotary actuator drives the drive gear to rotate, causing the driven gear, the first rotating shaft, and the first turntable to rotate significantly. This, in turn, causes the second rotating shaft, the second turntable, and the workpiece to rotate significantly, achieving rapid coarse angle adjustment. Then, the air supply is precisely controlled to precisely control the protrusion length of each inner guide tube, which in turn causes the two transmission plates to rotate slightly. This, in turn, causes the second rotating shaft, the second turntable, and the workpiece to rotate slightly, achieving fine angle adjustment. This ensures the positional accuracy and routing accuracy of the third blind hole.
[0025] 3. Two first limiting mechanisms limit the workpiece at different positions on the same side, effectively preventing workpiece swaying and suitable for machining holes in irregularly shaped parts. One of the first limiting mechanisms can contact the first connecting part of the workpiece. When forming the first blind hole, it can prevent the first connecting part from moving away from the drilling machine, ensuring drilling efficiency and effect. The other first limiting mechanism can contact one end of the second connecting part of the workpiece.

[0026] 4. The first, second, and third tightening bolts respectively control the positions of the first, second, and third pressure plates, ensuring a tight fit between these plates and the ends of the first / second connecting parts. Even if the ends of the first / second connecting parts are irregularly shaped (curved or sloping), reliable positioning is guaranteed. The first, second, and third pressure plates generate clamping force on three sides, dispersing the clamping force and preventing damage to the workpiece from single-point clamping. This also ensures positioning accuracy.
[0027] 5. After the workpiece is placed at the top of the angle adjustment mechanism, the second linear actuator actuates, causing the pressure block to move rapidly towards the workpiece to quickly contact the second connecting part, ensuring the limiting efficiency. When forming the third blind hole, the second limiting mechanism prevents the workpiece from moving away from the drilling machine, ensuring drilling efficiency and drilling effect. On the one hand, the limiting groove helps improve positioning accuracy; on the other hand, the limiting groove prevents slight swaying of the workpiece, ensuring the drilling effect.
[0028] 6. After the workpiece is placed at the top of the angle adjustment mechanism, the second rotary driver actuates, causing the pressure seat to move rapidly downwards to quickly contact the top surface of the third connecting part, ensuring efficient positioning. The third limiting mechanism applies adjustable pressure to the top surface of the third connecting part, effectively suppressing upward movement of the workpiece and ensuring that no burrs or chipping occurs at the orifice. By controlling the rotation angle of the second rotary driver, stepless adjustment of the clamping force can be achieved, suitable for clamping workpieces of different hardness, such as plastic, aluminum, and steel parts.

The length direction of the third connecting portion 330 forms a preset angle with the length direction of the first connecting portion 310 / second connecting portion 320, and the preset angle is 30°-60°. A first blind hole 311 is formed on the first connecting portion 310 along its length direction. A second blind hole 321 is formed on the second connecting portion 320 along its length direction. A third blind hole 331 is formed on the third connecting portion 330 along its length direction. The third blind hole 331 communicates with both the first blind hole 311 and the second blind hole 321. The process of creating three blind holes on workpiece 300 is as follows: first, create the first blind hole 311 on workpiece 300; then, create the second blind hole 321 on workpiece 300; and finally, create the third blind hole 331 on workpiece 300.

The first position adjustment mechanism 110 drives the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis. The second position adjustment mechanism 120 is mounted on the first position adjustment mechanism 110 and drives the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis. The angle adjustment mechanism 130 is mounted on the second position adjustment mechanism 120, and its top surface is used to support the workpiece 300. The angle adjustment mechanism 130 drives the workpiece 300 to rotate around the Z-axis. The first limiting mechanism 140 is mounted on the angle adjustment mechanism 130 and can contact one side of the workpiece 300 to restrict the movement of the workpiece 300.

The third limiting mechanism 160 actuates, contacting the top surface of the workpiece 300. Afterwards, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a first blind hole 311 on the workpiece 300. After completing the machining of the first blind hole 311, the drilling machine 200 resets. Then, the first position adjustment mechanism 110 drives the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis direction, and the second position adjustment mechanism 120 drives the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis direction. Next, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a second blind hole 321 on the workpiece 300. After machining the second blind hole 321, the drilling machine 200 resets. Then, the angle adjustment mechanism 130 drives the workpiece 300 to rotate around the Z-axis, the first position adjustment mechanism 110 drives the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis, and the second position adjustment mechanism 120 drives the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis. Next, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a third blind hole 331 on the workpiece 300. After machining the third blind hole 331, the drilling machine 200 resets. Overall, the first position adjustment mechanism 110, the second position adjustment mechanism 120, and the angle adjustment mechanism 130 work together to replace manual adjustment of the workpiece 300's position, improving position adjustment efficiency and accuracy, which in turn helps improve the efficiency and accuracy of blind hole machining. The first limiting mechanism 140, the second limiting mechanism 150, and the third limiting mechanism 160 constrain the workpiece 300 in three orthogonal directions, effectively resisting the multi-directional cutting forces generated during drilling and preventing the workpiece 300 from moving. This is suitable for limiting irregularly shaped workpieces 300, ensuring drilling position accuracy and blind hole orientation accuracy. Multiple blind holes can be machined in a single clamping operation, eliminating the need for repeated clamping and releasing of the workpiece 300, thus improving blind hole machining efficiency.
[0034] Reference Figure 2 and Figure 6In one embodiment, the angle adjustment mechanism 130 includes a first rotating shaft 131, a first turntable 132, a driven gear 133, a driving gear 134, a first rotary driver 135, a second rotating shaft 136, a second turntable 137, two transmission plates 138, two fixing plates 1391, two outer guide tubes 1392, and two inner guide tubes 1393. The first rotating shaft 131 is vertically arranged and rotatably mounted on the top end of the second position adjustment mechanism 120. The first turntable 132 is fixed to the top end of the first rotating shaft 131 and rotates with the first rotating shaft 131. The driven gear 133 is sleeved on the first rotating shaft 131. The sidewall of the driving gear 134 meshes with the sidewall of the driven gear 133, and its diameter is smaller than that of the driven gear 133. The first rotary actuator 135 is fixed to the top of the second position adjustment mechanism 120. Its output shaft is fixedly connected to the drive gear 134, driving the drive gear 134 to rotate, which in turn drives the driven gear 133 and the first rotating shaft 131 to rotate, thereby driving the first turntable 132 to rotate. The second rotating shaft 136 is vertically arranged and rotatably mounted on the top of the first turntable 132. The second turntable 137 is fixed to the top of the second rotating shaft 136 and rotates with it. Two transmission plates 138 are fixed to opposite sides of the second rotating shaft 136. Two fixing plates 1391 are fixed to opposite sides of the top surface of the first turntable 132. Both external guide tubes 1392 are arc-shaped. One end of each external guide tube 1392 is fixedly connected to one of the two fixing plates 1391. Each external guide tube 1392 has a vent 13921 formed at its end near the fixing plate 1391. The vent 13921 allows gas to be introduced into or expelled from the outer conduit 1392. Both inner conduits 1393 are arc-shaped. One end of each inner conduit 1393 is inserted into the other end of each outer conduit 1392, corresponding to the other end of the outer conduit 1392. The other ends are fixedly connected to the two transmission plates 138. The interiors of the two inner conduits 1393 and the two outer conduits 1392 are interconnected. Each outer conduit 1392 and each inner conduit 1393 is made of plastic or metal with a certain degree of hardness. During angle adjustment, the first rotary driver 135 first drives the drive gear 134 to rotate, causing the driven gear 133, the first rotating shaft 131, and the first turntable 132 to rotate significantly. This, in turn, causes the second rotating shaft 136, the second turntable 137, and the workpiece 300 to rotate significantly, achieving rapid coarse angle adjustment. Then, the gas supply is precisely controlled to precisely control the protrusion length of each inner guide tube 1393, which in turn drives the two transmission plates 138 to rotate slightly, thereby driving the second rotating shaft 136, the second turntable 137, and the workpiece 300 to rotate slightly, in order to achieve the purpose of fine-tuning the angle. In this way, the positional accuracy and the orientation accuracy of the third blind hole 331 are ensured.
[0035] Preferably, the first rotary driver 135 can be a servo motor, which has high motion accuracy. The first rotary driver 135 can also be a stepper motor, which has lower manufacturing and maintenance costs.
[0036] Reference Figure 2 , Figure 7 and Figure 8 In one embodiment, there are two first limiting mechanisms 140, which can contact the same side of the workpiece 300. The two first limiting mechanisms 140 limit the workpiece 300 at different positions on the same side, effectively preventing the workpiece 300 from swaying, and are suitable for machining holes in irregularly shaped parts. It should be noted that one of the first limiting mechanisms 140 can contact the first connecting portion 310 of the workpiece 300. When forming the first blind hole 311, it can prevent the first connecting portion 310 from moving away from the drilling machine 200, ensuring drilling efficiency and drilling effect. The other first limiting mechanism 140 can contact one end of the second connecting portion 320 of the workpiece 300. When forming the second blind hole 321, it can prevent the second connecting portion 320 from moving away from the drilling machine 200, ensuring drilling efficiency and drilling effect. Each first limiting mechanism 140 includes a first linear actuator 141 and a pressing member 142. The first linear actuator 141 is fixed to the top of the angle adjustment mechanism 130. The pressing member 142 is fixedly connected to the output shaft of the first linear actuator 141 and can contact the workpiece 300. After the workpiece 300 is placed at the top of the angle adjustment mechanism 130, the first linear actuator 141 is activated, causing the pressing member 142 to move quickly toward the workpiece 300 so as to quickly contact the first connecting part 310 / second connecting part 320, thus ensuring the limiting efficiency.
[0037] Preferably, the first linear actuator 141 can be a pneumatic cylinder or a hydraulic cylinder, which provides high actuation accuracy. The first linear actuator 141 can also be an electric actuator, which does not require a medium to operate, ensuring the cleanliness of the working environment.
[0038] Preferably, the pressing member 142 includes an active plate 1421, a driven rod 1422, a limiting frame 1423, a first pressing plate 1424, a first tightening bolt 1425, a second pressing plate 1426, a second tightening bolt 1427, a third pressing plate 1428, and a third tightening bolt 1429. One side of the active plate 1421 is fixedly connected to the output shaft of the first linear actuator 141. One end of the driven rod 1422 is fixedly connected to the other side of the active plate 1421. One side of the limiting frame 1423 is fixedly connected to the other end of the driven rod 1422, and the other side is an open structure with a clearance cavity 14231 inside. The clearance cavity 14231 is used to avoid the ends of the first connecting part 310 / second connecting part 320. The first pressing plate 1424 is disposed on one side inside the clearance cavity 14231, and one side can contact one side of the ends of the first connecting part 310 / second connecting part 320 of the workpiece 300. The first tightening bolt 1425 is rotatably mounted on one side of the limiting frame 1423, with one end abutting against the other side of the first pressing plate 1424, enabling the first pressing plate 1424 to either make close contact with the workpiece 300 or to detach the first pressing plate 1424 from the workpiece 300. The second pressing plate 1426 is disposed on the other side within the relief cavity 14231, with one side able to contact the other side of the end of the first connecting portion 310 / second connecting portion 320 of the workpiece 300. The second tightening bolt 1427 is rotatably mounted on the other side of the limiting frame 1423, with one end abutting against the other side of the second pressing plate 1426, enabling the second pressing plate 1426 to either make close contact with the workpiece 300 or to detach the second pressing plate 1426 from the workpiece 300. The third pressure plate 1428 is disposed on one side of the relief cavity 14231, and one side of it can contact the other side of the end of the first connecting part 310 / second connecting part 320 of the workpiece 300. The third tightening bolt 1429 is rotatably mounted on the other side of the limiting frame 1423, and one end of it abuts against the other side of the third pressure plate 1428, which can make the third pressure plate 1428 in close contact with the workpiece 300 or make the third pressure plate 1428 detach from the workpiece 300. The positions of the first clamping plate 1424, the second clamping plate 1426, and the third clamping plate 1428 are controlled by the first clamping bolt 1425, the second clamping bolt 1427, and the third clamping bolt 1429, respectively, ensuring that the first clamping plate 1424, the second clamping plate 1426, and the third clamping plate 1428 are tightly fitted to the ends of the first connecting part 310 / second connecting part 320. Even if the ends of the first connecting part 310 / second connecting part 320 are irregularly shaped such as curved or inclined surfaces, the reliability of positioning can still be guaranteed. The first clamping plate 1424, the second clamping plate 1426, and the third clamping plate 1428 form a clamping force on three sides, which disperses the clamping force and avoids damage to the workpiece 300 caused by single-point clamping force. At the same time, it ensures positioning accuracy.
[0039] Reference Figure 2 , Figure 7 and Figure 9 In one embodiment, the second limiting mechanism 150 includes a second linear actuator 151 and a pressing block 152. The second linear actuator 151 is fixed to the top of the angle adjustment mechanism 130. The pressing block 152 is fixedly connected to the output shaft of the second linear actuator 151 and can contact the workpiece 300. After the workpiece 300 is placed on the top of the angle adjustment mechanism 130, the second linear actuator 151 actuates, causing the pressing block 152 to move rapidly toward the workpiece 300 to quickly contact the second connecting part 320, ensuring limiting efficiency. When forming the third blind hole 331, the second limiting mechanism 150 can prevent the workpiece 300 from moving away from the drilling machine 200, ensuring drilling efficiency and drilling effect.
[0040] Preferably, the second linear actuator 151 can be a pneumatic cylinder or a hydraulic cylinder, which provides high operational precision. The second linear actuator 151 can also be an electric actuator, which operates without a medium, ensuring a clean working environment.
[0041] Preferably, a limiting groove 1521 is formed on the side of the pressing block 152 away from the second linear actuator 151. On the one hand, the limiting groove 1521 helps to improve positioning accuracy; on the other hand, the limiting groove 1521 can prevent the workpiece 300 from wobbling slightly, thus ensuring the drilling effect.
[0042] Reference Figure 2 , Figure 7 and Figure 10In one embodiment, the third limiting mechanism 160 includes a support base 161, a pressing base 162, a lead screw 163, a lead screw nut 164, and a second rotary driver 165. The support base 161 is fixed to the top of the angle adjustment mechanism 130. The pressing base 162 is movably mounted on the support base 161. It should be noted that one end of the pressing base 162 is slidably connected to the support base 161 via a slide groove and a slide rail to ensure smooth vertical movement of the pressing base 162. The lead screw 163 is vertically arranged and rotatably mounted on the support base 161. The lead screw nut 164 is sleeved on the lead screw 163 and fixedly connected to the pressing base 162. The second rotary driver 165 is mounted on the top of the support base 161, and its output shaft is fixedly connected to the top of the lead screw 163, used to drive the lead screw 163 to rotate, thereby driving the lead screw nut 164 and the pressing base 162 to move vertically. After the workpiece 300 is placed at the top of the angle adjustment mechanism 130, the second rotary driver 165 actuates, causing the pressure seat 162 to move rapidly downwards to quickly contact the top surface of the third connecting part 330, ensuring effective positioning. It should be noted that when the drill bit of the drilling machine 200 exits the blind hole, the workpiece 300 tends to move upwards. The third limiting mechanism 160 applies adjustable pressure to the top surface of the third connecting part 330, effectively suppressing the upward movement of the workpiece 300 and ensuring that no burrs or chipping occurs at the hole opening. By controlling the rotation angle of the second rotary driver 165, stepless adjustment of the clamping force can be achieved, suitable for clamping workpieces 300 of different hardnesses, such as plastic, aluminum, and steel parts.
[0043] Preferably, the second rotary driver 165 can be a servo motor, which has high motion accuracy. The second rotary driver 165 can also be a stepper motor, which has lower manufacturing and maintenance costs.
[0044] Reference Figure 2 and Figure 11In one embodiment, the first position adjustment mechanism 110 includes a base plate 111, a first linear module 112, and a first movable seat 113. The base plate 111 provides support. The first linear module 112 is arranged along the X-axis and fixed to the top of the base plate 111. The first movable seat 113 is disposed above the base plate 111, with one side of its bottom end fixedly connected to the sliding seat of the first linear module 112, and the other side of its bottom end slidably connected to the top surface of the base plate 111 via a groove and a slide rail. The first linear module 112 can drive the first movable seat 113 to move along the X-axis, thereby driving the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis. The second position adjustment mechanism includes a second linear module 121 and a second movable seat 122. The second linear module 121 is arranged along the Y-axis and fixed to the top of the first movable seat 113. The second movable seat 122 is disposed above the first movable seat 113. One side of its bottom end is fixedly connected to the sliding seat of the second linear module 121, and the other side of its bottom end is slidably connected to the top surface of the first movable seat 113 via a sliding groove and a slide rail. The second linear module 121 can drive the second movable seat 122 to move along the Y-axis direction, thereby driving the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis direction.
[0045] This application also discloses a drilling apparatus, including a controller, a drilling machine 200, and the aforementioned drilling position adjustment device 100. The drilling machine 200 is disposed on one side of the drilling position adjustment device 100 and is used to generate a first blind hole 311, a second blind hole 321, and a third blind hole 331 on the workpiece 300. It should be noted that the drill bit of the drilling machine 200 is rotatable. The drilling machine 200 as a whole is capable of moving along its own axial direction. The controller is electrically connected to the drilling machine 200, the first position adjustment mechanism 110, the second position adjustment mechanism 120, the angle adjustment mechanism 130, the first limiting mechanism 140, the second limiting mechanism 150, and the third limiting mechanism 160, respectively, and is used to control its operation.
[0046] The implementation principle of this embodiment is as follows: First, the workpiece 300 is placed on the top surface of the angle adjustment mechanism 130. Then, the first limiting mechanism 140 is activated, contacting one side of the workpiece 300. The second limiting mechanism 150 is activated, contacting one end of the workpiece 300. The third limiting mechanism 160 is activated, contacting the top surface of the workpiece 300. Afterward, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a first blind hole 311 on the workpiece 300. After completing the machining of the first blind hole 311, the drilling machine 200 is reset. Then, the first position adjustment mechanism 110 drives the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis direction, and the second position adjustment mechanism 120 drives the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis direction. Next, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a second blind hole 321 on the workpiece 300. After machining the second blind hole 321, the drilling machine 200 resets. Then, the angle adjustment mechanism 130 drives the workpiece 300 to rotate around the Z-axis, the first position adjustment mechanism 110 drives the second position adjustment mechanism 120, the angle adjustment mechanism 130, and the workpiece 300 to move along the X-axis, and the second position adjustment mechanism 120 drives the angle adjustment mechanism 130 and the workpiece 300 to move along the Y-axis. Next, the drill bit of the drilling machine 200 rotates, and the drilling machine 200 moves along its own axial direction, creating a third blind hole 331 on the workpiece 300. After machining the third blind hole 331, the drilling machine 200 resets. Overall, the first position adjustment mechanism 110, the second position adjustment mechanism 120, and the angle adjustment mechanism 130 work together to replace manual adjustment of the workpiece 300's position, improving position adjustment efficiency and accuracy, which in turn helps improve the efficiency and accuracy of blind hole machining. The first limiting mechanism 140, the second limiting mechanism 150, and the third limiting mechanism 160 constrain the workpiece 300 in three orthogonal directions, effectively resisting the multi-directional cutting forces generated during drilling and preventing the workpiece 300 from moving. This is suitable for limiting irregularly shaped workpieces 300, ensuring drilling position accuracy and blind hole orientation accuracy. Multiple blind holes can be machined in a single clamping operation, eliminating the need for repeated clamping and releasing of the workpiece 300, thus improving blind hole machining efficiency.
