Description

Technical Field

[0001] The present invention relates to the technical field of machine tool feed control, and more specifically, to a feed control device for industrial machine tools. Background Art

[0002] Machine tool feed control is a vital part of CNC machine tools. It directly affects machining accuracy, surface quality and production efficiency. When a feed path is completed, the control system will command the tool to exit the cutting area and prepare for the next feed.

[0003] When machining radial deep holes on workpieces, two methods are generally used: one-time drilling and step-by-step drilling. One-time drilling uses a special deep hole drilling tool to drill a radial deep hole at one time. When the workpiece is made of hardened steel or titanium alloy, special deep hole drilling tools and techniques such as gun drilling and BTA (blind deep hole drilling technology) cannot be used because the tool wears quickly and may even break. In addition, when drilling radial deep holes, chip discharge is difficult and chip blockage is easy to occur.

[0004] Therefore, the prior art adopts a step-by-step drilling method to process radial deep holes on hardened steel or titanium alloy workpieces. The feed of the machine tool is divided into two stages. First, the drilling points are marked at the relative positions on both sides. In the first stage, the drill bit is aligned with the drilling point on one side, and then the drill bit is started to drill. At this time, the feed stroke of the drill bit is half of the designed depth of the radial deep hole. In the second stage, the drill bit is withdrawn and rotated to adjust the workpiece to align the drilling point on the other side with the drill bit, and finally the other half of the radial deep hole is completed.

[0005] Since the workpiece is fixed to the clamping position of the machine tool with a fixture, in the above-mentioned first stage, when multiple radial deep holes need to be machined axially on the workpiece, the feed of one side of the drill bit causes multiple impacts on the fixture. When the fixture becomes loose on the side close to the drill bit, the drilling point and the drill bit will deviate. At this time, the drilled hole also deviates from the originally designed hole. Since the feed path of the drill bit is fixed, when the drill bit is withdrawn in the second stage, the fixation of the workpiece is affected by the looseness. When the drill bit is withdrawn, the workpiece is pulled back to its original position by the drill bit. However, there is an angle between the drill bit and the machining surface of the workpiece and they are no longer perpendicular, resulting in the workpiece being unable to be reset. At the same time, the drill bit is stuck in the radial deep hole of the first stage and cannot be withdrawn, thereby failing to complete the second stage of processing. Summary of the invention

[0006] The present invention provides a feed control device for industrial machine tools, and aims to solve the problem that, when the existing feed control device for industrial machine tools performs step-by-step drilling of radial deep holes, since the processing is performed from one side, when the clamp is loosened so that the drilling point and the drill bit deviate, the drill bit cannot be withdrawn.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Embodiment 1 Refer to the instruction manual Figures 1 to 8 A feed control device for an industrial machine tool comprises a machine tool frame 1, a machine tool head 2 is mounted on the machine tool frame 1, a workpiece 23 is mounted on a workpiece mounting plate 21 of the machine tool head 2 through a clamp 1 211 and a clamp 2 212, a center calibrator 6 is mounted on the machine tool frame 1, and the center calibrator 6 is used to detect the inclination angle of the workpiece 23 relative to the workpiece mounting plate 21, a mounting table 3 is mounted on the machine tool frame 1, a drilling assembly 31 is mounted on the mounting table 3, and the drilling assembly 31 is located on the workpiece On one side of the workpiece 23, a designed drill hole 231 is provided in the radial direction through the center point of the workpiece 23, and both ends of the designed drill hole 231 are open. An angle adjustment mechanism is installed at the bottom of the mounting table 3, and an actual drill hole 232 is opened on the workpiece 23 through the drilling component 31. When there is an angle between the central axis of the workpiece 23 and the mounting surface of the workpiece mounting plate 21, the drilling component 31 is driven to rotate through the angle adjustment mechanism so that the output end of the drilling component 31 is perpendicular to the side of the actual drill hole 232 corresponding to the workpiece 23.

[0034] It should be noted that the clamp 1 211 and the clamp 2 212 are detachably fixed to the workpiece mounting plate 21 by screws, and the workpiece 23 is vertically fixed to the workpiece mounting plate 21. The clamp 1 211 is arranged close to one side of the drilling component 31, and the output end of the drilling component 31 is a drill bit.

[0035] In this embodiment, the implementation scenario is specifically as follows: the feeding of the drilling component 31 is divided into two stages. First, the drilling points are marked at both ends of the designed borehole 231. In the first stage: the drill bit of the drilling component 31 is aligned with the drilling point close to the side of the fixture 211, and then the drill bit of the drilling component 31 is fed to drill. At this time, the drill feeding stroke of the drilling component 31 is half of the depth of the designed borehole 231. In the second stage: the drill bit of the drilling component 31 is withdrawn, and the workpiece mounting plate 21 is rotated 180° to adjust the position of both sides of the workpiece 23, and the drilling point close to the side of the fixture 212 is aligned with the drill bit of the drilling component 31, and the drill bit of the drilling component 31 is fed to process the other half of the designed borehole 231 to complete the processing of the designed borehole 231. During the first stage, when the screw at the fixture 211 is loosened, under the feed push of the drilling component 31, refer to Figure 7 and Figure 8 , the central axis of the workpiece 23 deviates from the vertical line of the original vertical workpiece mounting plate 21, that is, there is an angle between the central axis of the workpiece 23 and the mounting surface of the workpiece mounting plate 21. At this time, the actual drilled hole 232 processed also deviates from the designed drilled hole 231. The drilling assembly 31 pulls the workpiece 23 to gradually return to its original position when it is retracted. Since the feed path of the drilling assembly 31 in the prior art is fixed, the drilling assembly 31 is frictionally blocked and cannot move due to the inner wall of the actual drilled hole 232 when it is retracted. In this embodiment, an angle adjustment mechanism is set to adjust the central axis of the workpiece 23 and the mounting surface of the workpiece mounting plate 21. When there is an angle between the mounting surfaces, the drilling assembly 31 is rotated to adjust the angle so that the drill bit of the drilling assembly 31 is perpendicular to the machining surface of the workpiece 23, that is, during the gradual resetting of the workpiece 23, the drill bit of the drilling assembly 31 is always maintained on the same horizontal line with the actual borehole 232, thereby reducing the friction of the inner wall of the actual borehole 232 on the drill bit and avoiding obstruction by the inner wall of the actual borehole 232, thereby ensuring the withdrawal of the drill bit of the drilling assembly 31 in the second stage. It should be noted that at this time, the workpiece 23, the fixture 1 211 and the fixture 2 212 are all discarded and need to be replaced with corresponding new components.

[0036] Furthermore, the angle adjustment mechanism includes a chassis 32, a connecting groove 323 is opened at the bottom of the chassis 32, a linear drive component 5 is installed on the machine tool frame 1, a rotary drive component 51 is installed on the linear drive component 5, and the output end of the rotary drive component 51 is fixedly connected to the connecting groove 323.

[0037] It should be noted that the linear drive assembly 2 5 is a linear guide rail or a lead screw, which is used to drive the mounting platform 3 and the chassis 32 to move horizontally.

[0038] Furthermore, a limiting groove 321 is provided on the chassis 32 , and a limiting column 322 passes through the limiting groove 321 , and the limiting column 322 is fixed to the linear drive assembly 2 5 .

[0039] It should be noted that the limiting grooves 321 are arranged in an arc shape, and two groups of limiting posts 322 are arranged corresponding to the limiting grooves 321 . The limiting grooves 321 and the limiting posts 322 play a limiting role when the chassis 32 rotates.

[0040] Furthermore, a linear drive component 4 is installed on the machine tool frame 1, and the output end of the linear drive component 4 is fixedly connected to the linear drive component 2 5. The linear drive component 1 4 drives the linear drive component 2 5 to move along the X-axis direction, and the linear drive component 2 5 drives the mounting table 3 to move along the Z-axis direction.

[0041] It should be noted that the X-axis direction is the direction from the machine tool head 2 to the center calibrator 6, and the Z-axis direction is determined according to the X-axis direction.

[0042] Furthermore, a rotary drive assembly 22 is installed on the machine tool head 2, and the output end of the rotary drive assembly 22 is transmission-connected to the workpiece mounting disk 21, and the center point of the workpiece mounting disk 21 and the detection end of the center calibrator 6 are located on the same horizontal line.

[0043] It should be noted that the rotary drive component 22 is a motor, and the output end of the rotary drive component 22 is connected to the workpiece mounting disk 21 through a belt, a gear or a coupling, thereby driving the workpiece mounting disk 21 to rotate.

[0044] Embodiment 2 Refer to the instruction manual Figures 6 to 12 A support frame 7 is provided on the machine tool frame 1, and the support frame 7 is located between the machine tool head 2 and the center calibrator 6. The workpiece 23 runs through the interior of the support frame 7. An installation box 73 and a buffer assembly 75 are provided on both sides of the interior of the support frame 7, and the installation box 73 and the buffer assembly 75 are respectively provided on both sides of the workpiece 23. The drilling assembly 31 is installed on the output end of the installation box 73. A two-way driving assembly 71 is provided between the installation box 73 and the buffer assembly 75. When the drilling assembly 31 feeds in the direction of the workpiece 23, the buffer assembly 75 is driven to feed in the direction of the workpiece 23 through the two-way driving assembly 71.

[0045] It should be noted that the drilling assembly 31 corresponds to the buffer assembly 75, and a mechanism for driving the drilling assembly 31 to feed is installed inside the installation box 73. The mechanism is a cylinder or an electric push rod. The input end of the bidirectional drive assembly 71 is fixed to the drilling assembly 31, and the output end of the bidirectional drive assembly 71 is fixed to the buffer assembly 75.

[0046] In this embodiment, the implementation scenario is specifically as follows: when the drilling component 31 is fed toward the workpiece 23 for processing, the buffer component 75 is synchronously fed toward the workpiece 23 through the bidirectional driving component 71, and the processing position of the drilling component 31 corresponds to the abutment position of the buffer component 75, that is, in the first stage of the feeding of the drilling component 31, a synchronously fed buffer component 75 is provided on the other side opposite to the processing position to provide reverse support for the feeding process of the drilling component 31, that is, refer to the attached diagram of the first embodiment. Figures 6 to 8 When the drilling component 31 is feeding and processing on one side of the clamp 1 211, the buffer component 75 is synchronously fed and supported on one side of the clamp 212 to prevent the workpiece 23 from being pushed by the drilling component 31 and tilting toward the clamp 2 212. Compared with the first embodiment, which operates after the workpiece 23 is deflected, the second embodiment can prevent the workpiece 23 from being deflected during the feeding process.

[0047] Furthermore, the bidirectional drive assembly 71 includes an intermediate gear 711, and a side plate assembly 72 is provided on the outer side of the intermediate gear 711. The side plate assembly 72 includes a side tooth plate 1 721 and a side tooth plate 2 722, and the side tooth plate 1 721 and the side tooth plate 2 722 are meshed and connected on both sides of the intermediate gear 711, one end of the side tooth plate 1 721 is fixed to the buffer assembly 75, and one end of the side tooth plate 2 722 is fixed to the drilling assembly 31.

[0048] It should be noted that the drilling assembly 31 feeds toward the workpiece 23, driving the side tooth plate 2 722 to move toward the buffer assembly 75. Fig.11 The side tooth plate 2 722 drives the intermediate gear 711 to rotate counterclockwise, so that the side tooth plate 1 721 moves toward the drilling assembly 31 , thereby driving the buffer assembly 75 to approach the workpiece 23 .

[0049] Furthermore, a guide groove 712 is opened inside the bidirectional driving assembly 71 , and guide posts 723 are fixedly provided on opposite sides of the side tooth plate 1 721 and the side tooth plate 2 722 , and the guide posts 723 are slidably arranged along the inside of the corresponding guide groove 712 .

[0050] It should be noted that when the side tooth plate 1 721 and the side tooth plate 2 722 move, the guide post 723 slides along the inside of the corresponding guide groove 712 to play a guiding role.

[0051] Furthermore, the buffer assembly 75 includes a damping box 751 and a support sleeve 752, and the support sleeve 752 is arranged on the side of the damping box 751 away from the workpiece 23, and the end of the damping box 751 away from the support sleeve 752 is penetrated by a telescopic block 753, one end of the telescopic block 753 is rotatably connected to the abutment wheel 754, and the abutment wheel 754 is used to abut the surface of the workpiece 23, one end of the support sleeve 752 is penetrated by a support rod 755, and one end of the support rod 755 is fixed between the telescopic block 753, a spring member 756 is provided inside the support sleeve 752, and the two ends of the spring member 756 are respectively fixedly connected to one end of the support rod 755 located inside the spring member 756 and one end inside the spring member 756.

[0052] It should be noted that the damping box 751 is filled with damping fluid, and the telescopic block 753 is cushioned by the damping fluid when performing piston movement. When the abutment wheel 754 no longer abuts the surface of the workpiece 23, the telescopic block 753 is reset by the elastic connection of the spring member 756.

[0053] Furthermore, a telescopic rod 74 runs through the interior of the installation box 73, and one end of the telescopic rod 74 is fixedly connected to the drilling assembly 31. A telescopic groove is opened inside the installation box 73 corresponding to the telescopic rod 74, and one end of the telescopic rod 74 away from the drilling assembly 31 is slidably arranged inside the telescopic groove.

[0054] It should be noted that the telescopic rod 74 cooperates with the telescopic slot to support and guide the drilling assembly 31 .

[0055] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
