Description

Technical Field

[0001] The invention relates to the technical field of drilling devices, and in particular to a deep hole processing axis deviation correction device. Background Art

[0002] With the continuous development of science and technology and the unremitting efforts of deep hole processing system manufacturers, deep hole processing has become a convenient and efficient processing method. It is widely used in fields such as automobile industry, aerospace industry, structural construction industry, medical equipment industry, mold / tool / jig industry, oil pressure, air pressure industry, etc. Gun drilling is an ideal deep hole processing solution. The use of gun drilling can achieve precise processing effects. The processed holes are precisely positioned, with high straightness and coaxiality, and have high surface finish and repeatability. It can easily process various forms of deep holes, and can also solve special deep holes, such as cross holes, blind holes and flat-bottomed blind holes. During deep hole processing, due to the long drill rod, the drill bit is prone to offset during long-distance work, resulting in the offset of the hole axis, affecting the quality of the final product, so a device that can monitor the offset in real time during the drilling process and correct it is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a deep hole processing axis correction device, which has the effects of real-time monitoring, timely correction, ensuring drilling effect and improving the quality of finished products.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: comprising a drill bit, a driving assembly for driving the drill bit to rotate, a drill rod connected to a supporting circular plate in the driving assembly, and a power assembly for driving the drill rod to rotate forward;

[0005] The driving assembly includes a driving plate fixed to an end face of the drill bit, a driving rod is vertically fixed on the driving plate, the driving rod passes through the arc plate 1 and the arc plate 2 in sequence, and the other end is vertically fixed to the driving block, the arc plates of the arc plate 1 and the arc plate 2 are provided with long strip through holes, the outer side surface of the arc plate 2 is fitted to the inner side surface of the arc plate 1, the driving block is slidably connected to the driving ball, the outer side surface of the driving ball is provided with two perpendicular concave annular grooves 1 and 2, the driving block is slidably connected to the annular groove 2 In the embodiment, the annular groove 2 and the arc plate 2 are located in the same horizontal plane, a fixed block is slidably connected in the annular groove 1 on the other side of the driving ball relative to the driving block, the fixed block is fixed to the supporting circular plate, the four sides of the supporting circular plate are evenly and vertically fixed with support plates, the two adjacent support plates are respectively fixed with driving motor 1 and driving motor 2, the output shafts of the driving motor 1 and driving motor 2 are respectively fixed to one end of the arc plate 1 and the arc plate 2, and the other ends of the arc plate 1 and the arc plate 2 are rotatably connected to the other two adjacent support plates;

[0006] The power assembly includes a power motor connected to the drill pipe, the power motor is fixed on a support plate, a support rod is vertically fixed to the bottom of the support plate, the support rod is vertically fixed to a sliding plate, the sliding plate is slidably connected to a parallel screw rod 1 and a slide rod 1, the screw rod 1 is rotatably connected to the base plate, and the end of the screw rod 1 is coaxially fixedly connected to the output shaft of the rotating motor through a coupling.

[0007] By adopting the above technical solution, the power component drives the drill rod to rotate, and the drill rod drives the supporting circular plate, i.e., the drill bit, to rotate, thereby realizing deep hole processing of the workpiece. When the drill bit deviates during movement, the driving motor 1 in the driving component drives the arc plate 1 to rotate. Since the driving rod passes through the arc plate 1, and the groove in the arc plate 1 is parallel to the annular groove 2, the driving block can slide in the arc groove 2. At this time, when the arc plate 1 drives the driving rod to rotate left and right, the arc plate 2 will not hinder the movement of the driving rod, that is, the arc plate 1 will drive the driving rod to rotate left and right when sliding in the annular groove 2, so the drill can be made to rotate left and right at first. The head is centered in the left and right directions; then the driving motor 2 is started again, and the driving motor 2 drives the arc plate 2 to rotate. At this time, the arc rod drives the driving block to rotate, and the driving block drives the driving ball to rotate. At this time, the arc plate 2 drives the driving rod to realize up and down rotation movement, that is, the drill bit is centered in the up and down directions, and finally the drill bit returns to the initial center position to avoid the axis deviation after the drill bit is offset, which affects the quality of the subsequent finished product; driving the drill bit to return to the center first is conducive to real-time correction during drilling, and the drill rod can be adjusted and returned to the center later to ensure the precise processing of the axis; the setting of the power component ensures the rotary drilling during the movement of the rotating rod.

[0008] The present invention is further configured as follows: an indicating assembly is arranged on the bottom plate away from the power motor, including an indicating tube sleeved on the outside of the drill rod, the inner wall of the indicating tube is evenly concavely provided with four hollow grooves, and pressure plates partially located outside the hollow grooves are slidably connected in the hollow grooves, and a spring is connected to the pressure plate located in the hollow groove, and the other end of the spring is connected to the inner wall surface of the circumference of the indicating tube, and the spring drives the four pressure plates to approach each other.

[0009] The present invention is further configured as follows: distance sensors are arranged on the end surfaces of the four pressure plates located in the hollow grooves.

[0010] By adopting the above technical solution, when the drill bit and the drill rod are offset, the pressure plate slides to varying degrees in the hollow groove, and the spring is deformed to varying degrees. At this time, the distance between the distance sensor and the inner wall of the hollow groove changes, so the value on the distance sensor changes, indicating that the drill rod is offset. The offset of the drill rod indicates that the drill bit is offset, indicating that the drill bit needs to be corrected first to ensure the accuracy of the axis.

[0011] The present invention is further configured as follows: an indicator band is evenly distributed on the end face of the indicator tube away from the power motor, an infrared emitter is evenly distributed on the end face of the drill bit close to the drive plate, and the infrared rays emitted by the infrared emitter correspond to the indicator hole in the middle of the indicator band.

[0012] By adopting the above technical solution and setting the indicator belt, the drill bit can be initially centered in the left and right horizontal directions. This action is the basis for subsequent centering in the upper and lower vertical directions. When the drill bit rotates to the point where the rays emitted by its two infrared generators in the vertical direction are on the upper and lower vertical indicator belts on the indicator tube, it is prompted that subsequent vertical rotation can be performed, so that the drill bit drills a hole and the rays emitted by the two infrared generators in the horizontal direction enter the horizontal indicator belt on the indicator tube. At this time, all four rays are aligned with the indicator holes in the middle of the four indicator belts to realize the centering of the drill bit. The movable drill bit and the fixed indicator tube are used to realize the centering of the offset drill bit, adjust the travel direction of the drill bit, and ensure the accuracy of drilling.

[0013] The present invention is further configured as follows: it also includes an adjusting mechanism, the adjusting mechanism includes an adjusting cylinder, the number of the adjusting cylinders is 4 and they are evenly distributed on the adjusting plate, a circular hole is provided in the center of the adjusting plate, the drill rod passes through the circular hole, the end of the piston rod of the adjusting cylinder is connected to an adjusting arc plate, and the adjusting plate is fixed to the base plate by a connecting rod.

[0014] The present invention is further configured as follows: the four pressure plates and the four regulating cylinders are arranged in a one-to-one correspondence in the horizontal and vertical directions.

[0015] By adopting the above technical solution, when deviation occurs, the drill bit is first corrected to ensure that the drilling will not deviate during movement and the head is always kept in a centered state. After the drill bit is corrected, the offset drill rod is corrected through the set adjustment mechanism. Since the adjusting cylinder and the pressure plate are set in a one-to-one correspondence, it is beneficial to drive the corresponding adjusting cylinder through the vertical change of the distance sensor on the pressure plate, so that the value on the distance sensor returns to the initial state, and finally drives the drill rod to be corrected. After the drill rod is corrected, the driving mechanism can still work to ensure the center state of the drill bit.

[0016] The present invention is further configured as follows: balls are provided on the sides of the adjusting arc plate and the pressure rod close to the drill rod.

[0017] By adopting the above technical solution, since the drill rod moves forward and rotates at the same time, the ball bearing helps to reduce the friction with the drill rod, thereby ensuring smooth drilling of the drill rod.

[0018] The present invention is further configured as follows: the groove widths of the annular groove one and the annular groove two are the same, the driving block is a rectangular parallelepiped, the wide side of which is the same as the width of the annular groove two and the long side is larger than the width of the annular groove two, the fixed block is configured the same as the driving block and is vertically slidably connected to the driving block in the annular groove one.

[0019] By adopting the above technical solution, the wide side of the driving block is the same as the width of the annular groove 2, so the driving block can slide in the annular groove 2, and the driving ball will not move at this time, which is conducive to adjusting the left and right position of the drill bit when the annular plate 1 rotates; the wide side of the driving block is larger than the width of the annular groove 2, then when the annular plate 2 rotates, it drives the driving block to rotate, and the driving block further drives the driving ball to rotate, and at this time, the fixed block and the driving ball move relative to each other, and the fixed block slides in the annular groove 1 to realize the vertical adjustment of the drill bit up and down.

[0020] The present invention is further configured as follows: the diameter of the drill bit is larger than the diameter of the supporting circular plate.

[0021] By adopting the above technical solution, the diameter of the drill bit is large, and the driving component will not contact the inner wall surface of the workpiece drill hole, ensuring that the driving component has space for working adjustment.

[0022] The beneficial effects of the present invention are as follows: the power assembly drives the drill rod to rotate, and the drill rod drives the supporting circular plate, i.e., the drill bit, to rotate, thereby realizing deep hole processing of the workpiece. When the drill bit deviates during movement, the driving motor 1 in the driving assembly drives the arc plate 1 to rotate. Since the driving rod passes through the arc plate 1, and the groove in the arc plate 1 is parallel to the annular groove 2, the driving block can slide in the arc groove 2. At this time, when the arc plate 1 drives the driving rod to rotate left and right, the arc plate 2 will not hinder the movement of the driving rod, that is, the arc plate 1 will drive the driving rod to rotate left and right when sliding in the annular groove 2, so the drill bit can be made to rotate left and right first. Return to the left and right positions; then start the driving motor 2, the driving motor 2 drives the arc plate 2 to rotate, at this time the arc rod drives the driving block to rotate, the driving block drives the driving ball to rotate, at this time the arc plate 2 drives the driving rod to realize up and down rotation movement, that is, the drill bit returns to the upper and lower positions, and finally the drill bit returns to the initial center position, avoiding the axis deviation after the drill bit is offset, which affects the quality of the subsequent finished product; driving the drill bit to return to the center first is conducive to real-time correction during drilling, and the drill rod can be adjusted and returned to the center later to ensure the precise processing of the axis; the setting of the power component ensures the rotary drilling during the movement of the rotating rod.

The power assembly 4 includes a power motor connected to the drill rod 3, and the power motor is fixed on the support plate 41. A support rod 42 is vertically fixed to the bottom of the support plate 41. The support rod 42 is vertically fixed to the sliding plate. The sliding plate is slidably connected to the parallel screw rod 1 and the sliding rod 1. The screw rod 1 is rotatably connected to the bottom plate 44. The end of the screw rod 1 is coaxially fixedly connected to the output shaft of the rotating motor through a coupling. The power assembly 4 drives the drill rod 3 to rotate, and the drill rod 3 drives the support circular plate 201, i.e., the drill bit 1 Rotate, and then realize deep hole processing of the workpiece. When the drill bit 1 deviates during the movement, the driving motor 1 211 in the driving assembly 2 drives the arc plate 1 204 to rotate. Since the driving rod 203 passes through the arc plate 1 204, and the groove in the arc plate 1 204 is parallel to the annular groove 209, the driving block 206 can slide in the arc groove 2. At this time, when the arc plate 1 204 drives the driving rod 203 to rotate left and right, the arc plate 205 will not hinder the movement of the driving rod 203, that is, the arc plate 1 204 will drive the driving rod 203 to rotate left and right when sliding in the annular groove 209, so the drill bit 1 can be firstly returned to the left and right position;Then start the second drive motor 212, the second drive motor 212 drives the second arc plate 205 to rotate, at this time the arc rod drives the driving block 206 to rotate, the driving block 206 drives the driving ball 207 to rotate, at this time the second arc plate 205 drives the driving rod 203 to realize the up and down rotation movement, that is, the drill bit 1 is returned to the upper and lower positions, and finally the drill bit 1 returns to the initial center position, avoiding the axis deviation after the drill bit 1 is offset, which affects the quality of the subsequent finished product; driving the drill bit 1 to return to the center first is conducive to real-time correction during the drilling process, and the drill rod 3 can be adjusted and returned to the center later to ensure the precise processing of the axis; the setting of the power component 4 ensures the rotary drilling during the movement of the rotating rod. ;

[0034] Furthermore, an indicating assembly 5 is provided on the bottom plate 44 away from the power motor, including an indicating tube 51 sleeved on the outside of the drill rod 3, the inner wall of the indicating tube 51 is evenly concavely provided with four hollow grooves 52, and pressure plates 53 partially located outside the hollow grooves 52 are slidably connected in the hollow grooves 52, and springs 54 are connected to the pressure plates 53 located in the hollow grooves 52, and the other end of the spring 54 is connected to the circumferential inner wall surface of the indicating tube 51, and the spring 54 drives the four pressure plates 53 to approach each other, and distance sensors 55 are provided on the end surfaces of the four pressure plates 53 located in the hollow grooves 52. When the drill bit 1 and the drill rod 3 are offset, the pressure plates 53 slide to varying degrees in the hollow grooves 52, and the springs 54 are also deformed to varying degrees. At this time, the distance between the distance sensor 55 and the inner wall surface of the hollow groove 52 changes, so the value on the distance sensor 55 changes, indicating that the drill rod 3 is offset. The offset of the drill rod 3 indicates that the drill bit 1 is offset, indicating that the drill bit 1 needs to be corrected first to ensure the accuracy of the axis.

[0035] Furthermore, indicator bands are evenly distributed on the end face of the indicator tube 51 away from the power motor, and infrared emitters 7 are evenly distributed on the end face of the drill bit 1 close to the driving plate 202. The infrared rays emitted by the infrared emitters 7 correspond to the indicator holes 56 in the middle of the indicator bands. By setting the indicator bands, the drill bit 1 can be initially corrected in the left and right horizontal directions. This action is the basis for subsequent correction in the upper and lower vertical directions. When the drill bit 1 rotates to the point where the rays emitted by its two infrared generators in the vertical direction are on the upper and lower vertical indicator bands on the indicator tube 51, it is prompted that subsequent vertical rotation can be performed, so that the drill bit 1 drills a hole and the rays emitted by the two infrared generators in the horizontal direction enter the horizontal indicator band on the indicator tube 51. At this time, all four rays are aligned with the indicator holes 56 in the middle of the four indicator bands to realize the correction of the drill bit 1. The movable drill bit 1 and the fixed indicator tube 51 are used to realize the correction of the offset drill bit 1, adjust the travel direction of the drill bit 1, and ensure the accuracy of drilling.

[0036] Furthermore, it also includes an adjustment mechanism, which includes an adjustment cylinder 61. The number of the adjustment cylinders 61 is 4 and they are evenly distributed on the adjustment plate 62. A circular hole is set in the center of the adjustment plate 62. The drill rod 3 passes through the circular hole. The end of the piston rod of the adjustment cylinder 61 is connected with an adjustment arc plate 63. The adjustment plate 62 is fixed to the bottom plate 44 through a connecting rod. The four pressure plates 53 and the four adjustment cylinders 61 are set one by one in horizontal and vertical directions. When deviation occurs, the drill bit 1 is first corrected to ensure that it will not deviate during travel. In case of drilling deviation, the head is always kept in the centered state. After the drill bit 1 is corrected, the offset drill rod 3 is corrected through the set adjustment mechanism. Since the adjusting cylinder 61 and the pressure plate 53 are set in a one-to-one correspondence, it is beneficial to drive the corresponding adjusting cylinder 61 through the vertical change of the distance sensor 55 on the pressure plate 53, so that the value on the distance sensor 55 returns to the initial state, and finally drives the drill rod 3 to return to the center. After the drill rod 3 is corrected, the driving mechanism can still work to ensure the center state of the drill bit 1.

[0037] Furthermore, the sides of the adjusting arc plate 63 and the pressure rod close to the drill rod 3 are provided with balls 8. Since the drill rod 3 moves forward and rotates at the same time, the balls 8 are helpful to reduce the friction with the drill rod 3, thereby ensuring smooth drilling of the drill rod 3.

[0038] Furthermore, the groove widths of the annular groove 1 208 and the annular groove 209 are the same, the driving block 206 is a rectangular parallelepiped, the wide side of which is the same as the width of the annular groove 209 and the long side is larger than the width of the annular groove 209, the fixed block 210 is configured the same as the driving block 206 and is vertically slidably connected to the driving block 206 in the annular groove 1 208, the wide side of the driving block 206 is the same as the width of the annular groove 209, then the driving block 206 can slide in the annular groove 209, at this time the driving ball 207 will not move, which is conducive to adjusting the left and right position of the drill bit 1 when the annular plate 1 rotates; the wide side of the driving block 206 is larger than the width of the annular groove 209, then when the annular plate 2 rotates, it drives the driving block 206 to rotate, and the driving block 206 further drives the driving ball 207 to rotate, and at this time the fixed block 210 and the driving ball 207 move relative to each other, and the fixed block 210 slides in the annular groove 1 208 to achieve the vertical adjustment of the drill bit 1 up and down.

[0039] Furthermore, the diameter of the drill bit 1 is larger than the diameter of the supporting circular plate 201. The larger the diameter of the drill bit 1, the less likely it is that the drive assembly 2 will come into contact with the inner wall of the workpiece hole, thus ensuring that the drive assembly 2 has space to work and adjust.

[0040] Working principle of a deep hole machining axis correction device:

[0041] When the screw in the power assembly 4 rotates, the sliding plate is driven to slide, so that the support plate 41 slides, and the power motor drives the drill rod 3 to rotate and slides at the same time, thereby drilling a hole in the workpiece.

[0042] When the value on the distance sensor 55 in the indicating assembly 5 changes, it indicates that the drill bit 1 is offset, and the driving motor 1 211 in the driving assembly 2 drives the arc plate 1 204 to rotate. Since the driving rod 203 passes through the arc plate 1 204, and the groove in the arc plate 1 204 is parallel to the annular groove 209, the driving block 206 can slide in the arc groove 2. At this time, when the arc plate 1 204 drives the driving rod 203 to rotate left and right, the arc plate 205 will not hinder the movement of the driving rod 203, that is, the arc plate 1 204 04 will drive the driving rod 203 to realize left and right rotation when sliding in the annular groove 209, so the drill bit 1 can be corrected in the left and right direction first; then the driving motor 212 is started, and the driving motor 212 drives the arc plate 205 to rotate. At this time, the arc rod drives the driving block 206 to rotate, and the driving block 206 drives the driving ball 207 to rotate. At this time, the arc plate 205 drives the driving rod 203 to realize up and down rotation movement, that is, the drill bit 1 is corrected in the up and down direction, and finally the drill bit 1 returns to the initial center position.

[0043] First, the drill bit 1 is corrected to ensure that the drilling will not deviate during movement and the head is always kept in the center state. After the drill bit 1 is corrected, the offset drill rod 3 is corrected through the set adjustment mechanism. Since the adjusting cylinder 61 and the pressure plate 53 are set in a one-to-one correspondence, it is beneficial to drive the corresponding adjusting cylinder 61 through the vertical change of the distance sensor 55 on the pressure plate 53, so that the value on the distance sensor 55 returns to the initial state, and finally drives the drill rod 3 to be corrected. After the drill rod 3 is corrected, the driving mechanism can still work to ensure the center state of the drill bit 1.
