Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, and particularly relates to an automatic CNC horizontal boring machine. Background Technology

[0002] A horizontal boring machine is a general-purpose machine tool with a horizontally arranged boring spindle as the core cutting component. It is mainly used to process large and complex workpiece hole systems, end faces and planes.

[0003] Existing horizontal boring machines require placing the workpiece on a machining table and clamping it in place. However, due to the large size and weight of the workpiece, cranes or forklifts are needed for lifting. Because the machining table lacks suitable vibration damping devices, a strong collision occurs when the workpiece is lowered too quickly. Since the bottom of the machining table typically has a rotating platform and precision rails, this collision can damage these components, affecting their accuracy and ultimately impacting the precision machining operation.

[0004] Therefore, it is necessary to invent an automatic CNC horizontal boring machine to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automatic CNC horizontal boring machine to solve the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic CNC horizontal boring machine, comprising:

[0007] A processing table, wherein a plurality of clamping slots are evenly provided on the top of the processing table along both sides;

[0008] A support bar is installed on the processing table to support the workpiece to be processed, and ball bearings are evenly installed on the top of the support bar.

[0009] A vibration damping device is installed at the bottom of the support bar to buffer the impact received by the support bar;

[0010] The adjustment device includes a movable bar, a U-shaped rod, a connector, and an adjusting component. The top of the processing table has a mounting groove for installing the support bar at the top of two adjacent clamping slots. The movable bar is located at the bottom of the support bar, and one end of the movable bar is slidably inserted into the inner wall of one side of the mounting groove. The sides of the movable bar and the support bar facing each other are designed with parallel inclined surfaces, and the height of the movable bar gradually increases towards its end outside the mounting groove. The U-shaped rod is horizontally slidably inserted into the processing table near the side of the movable bar extending out of the mounting groove, and the movable bar is connected to the U-shaped rod via the connector. The adjusting component is mounted on the U-shaped rod and is used to drive the U-shaped rod to move horizontally.

[0011] Furthermore, the vibration damping device includes a telescopic rod and a vibration damping spring. The top of the movable strip has several strip-shaped through holes. The telescopic rod is located in the through holes, and the top end of the telescopic rod is fixedly connected to the bottom of the support strip. The bottom end of the telescopic rod is in contact with the inner wall of the bottom of the mounting groove. The vibration damping spring is sleeved on the telescopic rod, and the two ends of the vibration damping spring are fixedly connected to the surfaces of the telescopic rod near the two ends.

[0012] Furthermore, the adjusting component includes a first adjusting rod, a fixed block, a movable tube, a return spring, and a locking component. The first adjusting rod is horizontally rotatable and inserted through the middle position of the U-shaped rod. The fixed block is aligned with the first adjusting rod and is fixedly connected to the processing table. The movable tube is horizontally slidably inserted through the fixed block. The first adjusting rod is threadedly inserted through the movable tube. An annular protrusion is provided at the end of the movable tube away from the U-shaped rod. The return spring is sleeved on the movable tube, and its two ends are fixedly connected to the fixed block and the annular protrusion, respectively.

[0013] Furthermore, the locking component includes a protrusion, a U-shaped retaining plate, and a locking screw. The protrusion is fixedly connected to the top of the movable tube away from the annular protrusion. The U-shaped retaining plate is slidably mounted on the top of the protrusion and is fixedly connected to the fixed block. The locking screw is vertically threaded through and inserted into the top of the U-shaped retaining plate, and the top end of the locking screw is inserted into the top of the protrusion.

[0014] Furthermore, the top of the movable strip is evenly provided with several grooves, and a roller is rotatably installed between the front and rear inner walls of the grooves, with the top of the roller being higher than the top surface of the movable strip.

[0015] Furthermore, the automatic CNC horizontal boring machine also includes a bed, a column, a boring headstock, a longitudinal rail, a transverse rail, and a control cabinet. The longitudinal rail is installed on the top of the bed, the column is vertically installed on the longitudinal rail, the boring headstock is installed on the front side of the column, and a spindle is slidably installed on the boring headstock along the vertical direction. The transverse rail is located on the front side of the bed, and the machining table is installed on the top of the transverse rail. The control cabinet is installed on the side of the bed.

[0016] Furthermore, in the initial state, the top of the support bar is higher than the top of the processing table. At this time, the height from the top of the support bar to the top of the processing table is equal to the maximum retraction of the telescopic rod, and the top of the ball is still higher than the top of the processing table.

[0017] Furthermore, in the initial state, the bottom of the support bar is separated from the top of the movable bar, and when the support bar and the movable bar are attached together, the maximum vertical adjustment height of the movable bar on the support bar is greater than the height of the ball bearing protruding from the top of the support bar.

[0018] Furthermore, the connector includes a second adjusting rod and a connecting block. The connecting block is hinged to one end of the movable bar near the U-shaped rod. The second adjusting rod is rotatably connected to the connecting block, and the second adjusting rod is horizontally threaded through and inserted into the U-shaped rod.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. This invention features a support bar. When a workpiece is placed on top of the support bar from top to bottom, the support bar can move downwards under pressure and compress the damping spring and telescopic rod, thereby converting the kinetic energy of the workpiece during downward movement into the elastic potential energy of the damping spring. This reduces the collision force between the workpiece and the support bar. Furthermore, during processing, when vibrations generated during workpiece processing are transmitted to the support bar, the support bar can transmit the vibrations to the damping spring, allowing the damping spring to absorb the vibrations during workpiece processing and reduce the impact of vibrations on the rotating platform and transverse track at the bottom of the processing table.

[0021] 2. The present invention provides a ball bearing at the top of the support bar. When the workpiece is separated from the top of the processing table under the support of the support bar, the workpiece can be pushed so that its position can be easily adjusted under the support of the ball bearing, thereby improving the convenience of workpiece adjustment.

[0022] 3. By providing a connecting member, when multiple support bars experience different wear conditions due to varying workpiece pressure, the second adjusting rod can be turned to allow each movable bar to be individually adjusted under the action of the corresponding second adjusting rod. This ensures that multiple support bars maintain contact with the bottom of the workpiece, thereby guaranteeing that all support bars can uniformly exert support force on the workpiece.

[0031] The technical solutions described below in conjunction with the embodiments will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figures 1 to 7An automatic CNC horizontal boring machine is shown, comprising: a machining table 1, a support bar 3, a vibration damping device, and an adjustment device; the top of the machining table 1 is evenly provided with several clamping grooves 2 along both sides; the top of the machining table 1 is provided with strip-shaped mounting grooves between two adjacent clamping grooves 2, the support bar 3 is installed in the mounting groove, the bottom of the mounting groove is provided with a drain hole for draining the coolant flowing into the mounting groove during boring, for supporting the workpiece to be processed, and the top of the support bar 3 is evenly provided with ball bearings 4; the vibration damping device is installed at the bottom of the support bar 3 for buffering the impact on the support bar 3, the vibration damping device includes a telescopic rod 7 and a vibration damping spring 8, the top of the movable bar 5 is provided with several strip-shaped through holes 9, the telescopic rod 7 is located in the through holes 9, and the top end of the telescopic rod 7 is fixedly connected to the bottom of the support bar 3, the bottom end of the telescopic rod 7 is in contact with the inner wall of the bottom of the mounting groove, the vibration damping spring 8 is sleeved on the telescopic rod 7, and the two ends of the vibration damping spring 8 are fixedly connected to the surfaces of the telescopic rod 7 near the two ends respectively;

[0033] In the initial state, the top of the support bar 3 is higher than the top of the processing table 1. At this time, the height from the top of the support bar 3 to the top of the processing table 1 is equal to the maximum retraction of the telescopic rod 7. At this time, the top of the ball 4 is still higher than the top of the processing table 1. In the initial state, the bottom of the support bar 3 is separated from the top of the movable bar 5. When the support bar 3 and the movable bar 5 are attached together, the maximum vertical adjustment height of the movable bar 5 on the support bar 3 is greater than the height of the ball 4 protruding from the top of the support bar 3.

[0034] The adjustment device includes a movable bar 5, a U-shaped rod 6, a connector, and an adjusting component. The movable bar 5 is located at the bottom of the support bar 3, and one end of the movable bar 5 is slidably inserted into the inner wall of one side of the mounting groove. The side of the movable bar 5 and the support bar 3 facing each other is designed with parallel inclined surfaces, and the height of the movable bar 5 gradually increases towards the end that is located outside the mounting groove. The U-shaped rod 6 is horizontally slidably inserted into the side of the processing table 1 near the side of the movable bar 5 that extends out of the mounting groove, and the movable bar 5 is connected to the U-shaped rod 6 through the connector. The adjusting component is installed on the U-shaped rod 6 and is used to drive the U-shaped rod 6 to move in the horizontal direction.

[0035] The automatic CNC horizontal boring machine also includes a bed 19, a column 20, a boring head 21, a longitudinal rail 22, a transverse rail 23, and a control cabinet 24. The longitudinal rail 22 is installed on the top of the bed 19, the column 20 is vertically installed on the longitudinal rail 22, the boring head 21 is installed on the front side of the column 20, and the spindle 25 is slidably installed on the boring head 21 along the vertical direction. The transverse rail 23 is located on the front side of the bed 19, and the machining table 1 is installed on the top of the transverse rail 23. The control cabinet 24 is installed on the side of the bed 19.

[0036] During processing, as the workpiece is placed on the processing table 1 from top to bottom, when the workpiece comes into contact with the support bar 3, the support bar 3 can move downward under pressure and compress the damping spring 8 and the telescopic rod 7. As the damping spring 8 is compressed, it can convert the kinetic energy of the workpiece when it moves downward into the elastic potential energy of the damping spring 8, thereby reducing the collision force between the workpiece and the support bar 3 and avoiding damage to the bottom rotating platform and the transverse track 23 of the processing table 1 due to the workpiece falling too fast.

[0037] As the support bar 3 moves downward, when the bottom of the support bar 3 contacts the movable bar 5, the support bar 3 can stop moving under the obstruction of the movable bar 5. At this time, since the ball bearing 4 is still higher than the top of the processing table 1, it can push the workpiece, so that the position can be easily adjusted under the support of the ball bearing 4. After the workpiece position is adjusted, the U-shaped bar 6 can be moved by the first adjusting rod 10. As the U-shaped bar 6 moves, the U-shaped bar 6 can pull the movable bar 5 to move closer to the U-shaped bar 6 through the connecting piece. As the movable bar 5 moves, the support bar 3 can move further downward. When the bottom of the workpiece contacts the top surface of the processing table 1, the workpiece can be stably placed on the top of the processing table 1. At this time, the fixing clamp can be installed in the clamping groove 2 and the workpiece can be clamped and fixed by the fixing clamp.

[0038] After the workpiece is fixed, the boring tool is installed on the spindle 25. Then, the column 20 can be moved along the longitudinal track 22, the machining table 1 can be moved along the transverse track 23, and the spindle 25 can be moved along the boring head holder 21 through the control cabinet 24. This achieves the position adjustment between the boring tool and the workpiece to be processed. After the adjustment is completed, the boring tool can be used to process the workpiece. During the processing, since the support bar 3 can be supported on the bottom of the workpiece by the elastic force of the damping spring 8, when the vibration generated during the workpiece processing is transmitted to the support bar 3, the support bar 3 can transmit the vibration to the damping spring 8. This allows the damping spring 8 to absorb the vibration during the workpiece processing and reduce the impact of the vibration on the bottom rotating platform of the machining table 1 and the transverse track 23.

[0039] like Figure 3 and Figure 7As shown, the adjusting component includes a first adjusting rod 10, a fixed block 11, a movable tube 12, a return spring 13, and a locking component. The first adjusting rod 10 is horizontally rotatable and inserted through the middle position of the U-shaped rod 6. The fixed block 11 is aligned with the first adjusting rod 10 and is fixedly connected to the processing table 1. The movable tube 12 is slidably inserted through the fixed block 11 in the horizontal direction. The first adjusting rod 10 is threaded through the movable tube 12. An annular protrusion 14 is provided at the end of the movable tube 12 away from the U-shaped rod 6. The return spring 13 is sleeved on the movable tube 12, and both ends of the return spring 13 are fixedly connected to the fixed block 11 and the annular protrusion 14, respectively.

[0040] The locking component includes a protrusion 15, a U-shaped retaining plate 16, and a locking screw 17. The protrusion 15 is fixedly connected to the top of the movable tube 12 away from the annular protrusion 14. The U-shaped retaining plate 16 is slidably mounted on the top of the protrusion 15 and is fixedly connected to the fixing block 11. The locking screw 17 is vertically threaded through and inserted into the top of the U-shaped retaining plate 16, and the top end of the locking screw 17 is inserted into the top of the protrusion 15.

[0041] By providing an adjustment mechanism, when processing some lighter workpieces, the locking screw 17 can be turned to move the locking screw 17 out of the protrusion 15. At this time, the U-shaped clamping plate 16 and the protrusion 15 are in an unlocked state. Thus, when the workpiece is placed on top of the support bar 3, the pressure of the workpiece on the support bar 3 can make it move downward and compress the telescopic rod 7 and the damping spring 8. As the damping spring 8 is compressed, the damping spring 8 can convert the kinetic energy of the workpiece when it moves downward into the elastic potential energy of the damping spring 8, thereby reducing the collision force between the workpiece and the support bar 3.

[0042] As the support bar 3 moves downward, when it comes into contact with the movable bar 5, the support bar 3 can exert pressure on the movable bar 5 through its bottom inclined surface. This allows the movable bar 5 to move towards the U-shaped rod 6 under pressure. As the movable bar 5 moves, the support bar 3 can continue to move downward, so that the top of the support bar 3 can gradually become flush with the top of the processing table 1. During this process, the first adjusting rod 10 can drive the movable tube 12 to move together under the pull of the U-shaped rod 6. This allows the movable tube 12 to drive the annular protrusion 14 to squeeze the return spring 13. As the return spring 13 is compressed, it can work with the damping spring 8 to further absorb the kinetic energy of the workpiece when it moves downward, thus preventing damage to the bottom rotating platform and the transverse track 23 of the processing table 1 due to the workpiece falling too fast.

[0043] When the ball bearing 4 at the top of the support bar 3 is flush with the top of the processing table 1, both the support bar 3 and the movable bar 5 stop moving. At this time, the workpiece can be supported by the top of the processing table 1 and multiple support bars 3. Since the workpiece is relatively light, it is relatively easy to push the workpiece along the top of the processing table 1 to adjust its position. After the workpiece is processed, as the workpiece is removed from the top of the processing table 1, the damping spring 8 can push the support bar 3 to reset upward under its own elastic force, and the reset spring 13 can push the movable tube 12 to reset under its own elastic force. As the movable tube 12 resets, the U-shaped rod 6 can push multiple movable bars 5 to gradually reset under the pulling force of the first adjusting rod 10.

[0044] When processing large and heavy workpieces, the U-shaped clamp 16 can be connected to the protrusion 15 by the locking screw 17. At this time, the movable tube 12 and the fixed block 11 are locked. So when the workpiece is placed on top of the support bar 3, the support bar 3 can move downward under the pressure of the workpiece and compress the telescopic rod 7 and the damping spring 8. When the bottom of the support bar 3 contacts the movable bar 5, the support bar 3 can stop moving under the obstruction of the movable bar 5. At this time, the top of the ball 4 is still higher than the top of the processing table 1, so the workpiece can be pushed and its position can be easily adjusted under the support of the ball 4. After the adjustment is completed, the first adjusting rod 10 can be turned, so that the U-shaped rod 6 pulls multiple movable bars 5 towards the direction of the U-shaped rod 6 under the action of the first adjusting rod 10, thereby realizing the further downward movement of the support bar 3. When the bottom of the workpiece contacts the top of the processing table 1, the first adjusting rod 10 is stopped. At this time, the workpiece can be stably stopped on the top of the processing table 1.

[0045] like Figure 5 and Figure 6 As shown, the top of the movable strip 5 is evenly provided with several grooves, and a roller 18 is rotatably installed between the front and rear inner walls of the grooves, and the top of the roller 18 is higher than the top surface of the movable strip 5.

[0046] By providing a roller 18 at the top of the movable strip 5, when the movable strip 5 moves along the bottom of the support strip 3, the roller 18 can convert the sliding friction between the movable strip 5 and the support strip 3 into rolling friction, thereby reducing the friction between the movable strip 5 and the support strip 3, so that the support strip 3 can move more smoothly along the vertical direction under the action of the movable strip 5.

[0047] like Figure 3 As shown, the connector includes a second adjusting rod 26 and a connecting block 27. The connecting block 27 is hinged to one end of the movable bar 5 near the U-shaped rod 6. The second adjusting rod 26 is rotatably connected to the connecting block 27, and the second adjusting rod 26 is horizontally threaded through and inserted into the U-shaped rod 6.

[0048] During the use of the processing table 1, due to the different sizes and weight distributions of the workpieces to be processed, the forces exerted on the multiple support bars 3 also differ. Therefore, as the movable bar 5 pushes the support bar 3, the different frictional forces between the movable bar 5 and the support bar 3 lead to varying degrees of wear between each movable bar 5 and the support bar 3. Over time, gaps may appear between the support bar 3 and the movable bar 5, resulting in the support bars 3 not being able to evenly support the bottom of the workpiece. At this point, a connecting piece is provided so that when the bottom is flat and the dimensions are sufficient... After a sufficiently large workpiece is placed on top of all the support bars 3, the second adjusting rod 26 can be turned one by one. When the top of the support bar 3 is not in close contact with the bottom of the workpiece, the movable bar 5 can move away from the U-shaped rod 6 under the action of the second adjusting rod 26 as the second adjusting rod 26 rotates. As the movable bar 5 moves, it can push the support bar 3 upward, so that the top of the support bar 3 is in close contact with the bottom of the workpiece. In this way, multiple support bars 3 can be adjusted individually, ensuring that all support bars 3 can provide uniform support force to the workpiece.

[0049] It should be noted that, based on the above embodiments of the present invention, those skilled in the art can fully realize the scope of the independent claims and dependent claims of the present invention, and the implementation process and methods are the same as those in the above embodiments; and the parts of the present invention not described in detail belong to the well-known technology in the art. However, the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the protection scope of the present invention.
