Abstract
Description
Technical Field
[0001] This invention relates to the field of workpiece clamping technology, and more specifically, to a rapid clamping integrated device and method for boring machines. Background Technology
[0002] The boring machine clamping device is a key piece of equipment used to accurately position and firmly clamp the workpiece during the boring process. Its core function is to ensure that the workpiece maintains a stable and reliable position during machining in order to withstand the cutting force and achieve the required machining accuracy. The device must have sufficient rigidity, accurate positioning reference and convenient operation to ensure that the positional accuracy, roundness, dimensional accuracy and surface quality of the boring hole meet the process requirements.
[0003] Patent application number CN202021290382.3 discloses a boring machine with wide clamping adaptability, which includes a base and a worktable. The surface of the worktable is provided with several fixed through slots along the width direction parallel to the base. The surface of the worktable is provided with a clamping mechanism for fixing different workpieces. The clamping mechanism includes a pair of clamping components with the same structure. A limiting crossbeam is provided between the two adjustable horizontal clamping frames to limit and fix the workpiece in the vertical direction, thereby improving the adaptability of the boring machine in clamping and fixing workpieces.
[0004] However, traditional clamps require manual adjustment of the clamping mechanisms on both sides and lack self-locking function. After horizontal clamping, additional manual locking is required to prevent displacement, significantly extending the clamping time. The clamping process lacks elastic buffering, which can easily cause damage and deformation to thin-walled or precision workpieces due to rigid contact. The clamping of the top of the workpiece requires independent operation, such as manually tightening the pressure plate bolts, which cannot be linked with the horizontal clamping. This increases the intensity of manual intervention and may lead to uneven clamping or overpressure due to inaccurate pressure control. These fragmented multi-step operation modes force clamping time to account for an excessively high proportion of the processing cycle.
[0005] In view of this, we propose a rapid clamping integrated device and method for boring machines. Summary of the Invention
[0006] The purpose of this invention is to provide a quick clamping and integration device and method for boring machines to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A boring machine quick clamping integrated device includes a placement table and a driving device disposed inside the placement table. The top surface of the placement table is provided with a pair of clamping mechanisms and a clamping mechanism disposed inside the clamping mechanisms.
[0009] The pressing mechanism includes a transverse frame, two symmetrically arranged toothed plates, a guide block disposed above the transverse frame, and a pressing part disposed inside the guide block. The guide block has a guide groove inside.
[0010] This setting enables the drive device to move a pair of transverse frames towards each other, causing the guide blocks to move together;
[0011] The pressing part includes a pressing strip, a connecting rod disposed in the groove on its outer side, and a pressing block that moves with the pressing strip;
[0012] This setting moves the guide block inward, driving the connecting rod to move along the guide groove, allowing the pressure bar and the pressure block to move downward synchronously;
[0013] The clamping mechanism includes a transverse plate, a connecting frame snapped onto the outside of the transverse plate, a second spring sleeved on the end round rod of the connecting frame, and a pair of positioning parts;
[0014] This setting describes how the transverse frame presses against the second spring, causing the transverse plate to move to the outer wall of the workpiece, and then compresses the second spring, causing the toothed plate and guide block to move inward;
[0015] The positioning part includes a lead screw, a pressing frame sleeved on the outside of the lead screw, and a rod tooth engaged with the end of the lead screw;
[0016] In this configuration, the toothed plate moves inward, the meshing rod drives the lead screw to rotate, and the pressure frame moves upward to fix the transverse plate.
[0017] In the technical solution of the present invention, the placement platform includes a pair of support plates and a platform plate fixedly connected to the top of the pair of support plates by bolts. A pair of first sliding grooves that run vertically through the center of the top surface of the platform plate are provided. A second sliding groove is provided on both sides of the pair of first sliding grooves on the top surface of the platform plate. A pair of plate surface through grooves that run through the bottom surface of the second sliding grooves are provided.
[0018] This setting provides a stable operating platform for quick workpiece clamping.
[0019] In the technical solution of the present invention, the driving device includes a motor fixedly connected to the outer wall of the support plate by bolts and a bidirectional lead screw coaxially connected to the output shaft of the motor, the other end of which is rotatably connected to the inside of the support plate.
[0020] This setup enables rapid workpiece clamping through a single power source—the motor—in conjunction with the internal structures of the clamping and holding mechanisms.
[0021] In the technical solution of the present invention, the pressing mechanism further includes a bracket disposed between the transverse frame and the guide block and a slide rod disposed inside the pressing part. The bottom protrusion of the transverse frame is slidably connected to the inside of the first slide groove and threadedly connected to the bidirectional lead screw. An abutment block is integrally formed on the inner wall of the transverse frame.
[0022] In the technical solution of the present invention, the toothed plate is fixedly connected to the inner wall of the transverse frame by bolts, the bottom end of the bracket is fixedly connected to the top surface of the transverse frame by bolts, and the guide block is snapped and fixed to the top surface of the bracket.
[0023] After the bidirectional lead screw rotates as described above, it can drive the pressing part and the clamping mechanism to move towards the workpiece through the transverse frame.
[0024] In the technical solution of the present invention, the pressing part further includes a telescopic rod that is snapped between the pressing strip and the pressing block, and a first spring sleeved on the outside of the telescopic rod. The elastic force provided by the first spring is used to push the pressing block to move downward, and the pressing strip is slidably connected to the outside of the sliding rod.
[0025] This feature allows the clamping mechanism to press down on the top of the workpiece during the clamping process by using a guide block in conjunction with a pressing part, thereby reducing the need for manual tightening of bolts and speeding up the workpiece clamping operation.
[0026] In the technical solution of the present invention, the clamping mechanism further includes a pair of clamping blocks fixedly connected to the top surface of the transverse plate by bolts and a pair of sliders welded to the bottom surface of the transverse plate. The sliders are slidably connected to the inside of the second slide groove and the plate surface through groove. The inside of the sliders is provided with a slot that runs through the left and right sides. The bottom end of the slide rod is fixedly connected to the top surface of the transverse plate by bolts.
[0027] In the technical solution of the present invention, the round rod at the end of the connecting frame is fixedly connected to the outer wall of the transverse plate by bolts, the inner end of the second spring is welded and fixed to the outer wall of the transverse plate, and the elastic force provided by the second spring is used to push the entire pressing mechanism to move outward.
[0028] The above-mentioned configuration, through the second spring, allows the clamping mechanism to continue to move inward after the workpiece is clamped, further improving the workpiece clamping effect. At the same time, it can also drive the guide block to make the pressing part press down on the workpiece.
[0029] In the technical solution of the present invention, the positioning part further includes a base plate for placing the pressing frame and round rods that are snapped onto both ends of the top surface of the base plate. The top end of the round rods is snapped onto the bottom surface of the slider. The lead screw is rotatably connected to the inside of the slider. The pressing frame is slidably connected to the two round rods, and the two ends of the pressing frame protrude on both sides of the through groove on the plate surface.
[0030] This setting, when the workpiece is clamped, uses the engagement of the toothed plate and the teeth of the lever to fix the overall position of the clamping mechanism, thus ensuring the stability of subsequent processing.
[0031] On the other hand, the present invention also provides a method for quick clamping of a boring machine, using the above-mentioned quick clamping integrated device for a boring machine, comprising the following steps:
[0032] S1. First, place the workpiece to be processed in the center of the table and start the motor to drive the bidirectional lead screw to rotate.
[0033] S2. After the bidirectional lead screw rotates, it drives the transverse frame in the clamping mechanism at both ends of the workpiece to move towards each other. At the same time, the transverse frame presses against the second spring, driving the transverse plate to move synchronously towards the workpiece.
[0034] S3. Subsequently, the clamping block on the top surface of the transverse plate abuts against the outer wall of the workpiece, while the transverse frame, which continues to move inward, continuously compresses the second spring until the pressing block abuts against the transverse plate, at which point the motor is turned off.
[0035] S4. During this process, the reaction force provided by the second spring acts on the workpiece surface through the clamping block, and during the inward displacement of the toothed plate, the meshing rod drives the lead screw to rotate, causing the pressure frame to move upward, and pressing its two ends against the bottom surface of the platform, thereby fixing the transverse plate.
[0036] S5. At the same time, during the inward displacement of the guide block in the pressing mechanism, the connecting rod of the lower pressing part is driven to move along the guide groove, which in turn drives the pressure bar to move downward.
[0037] S6. After the pressure block comes into contact with the top surface of the workpiece, the continuously moving pressure bar will compress the first spring, and the increased elastic potential energy through the first spring will act on the surface of the workpiece.
[0038] S7. Subsequently, after the boring machine completes the machining of the workpiece, the motor drives the bidirectional lead screw to rotate in the opposite direction, thereby restoring the positions of the pair of clamping mechanisms and holding mechanisms.
[0039] Compared with the prior art, the beneficial effects of the present invention are:
[0040] 1. The boring machine quick clamping integrated device and method, through the synchronous driving of the two transverse moving frames on both sides by the bidirectional lead screw, combined with the elastic buffer of the second spring, realizes the flexible clamping of the workpiece in the side, avoiding rigid impact damage to the workpiece; at the same time, after the transverse moving frame is in place, the linkage structure of the tooth plate and the meshing rod tooth automatically triggers the pressure frame to move up and lock the bottom surface of the table, forming a rigid self-locking. Under the drive of a single motor, the adaptive clamping and position locking of the workpiece are completed in one go, which greatly improves the clamping efficiency and stability.
[0041] 2. The boring machine quick clamping integrated device and method, the inward displacement of the transverse frame synchronously drives the guide block to move, forcing the connecting rod to slide along the inclined guide groove, converting the horizontal movement into the vertical downward pressure of the pressure bar; when the pressure block contacts the workpiece, the first spring is compressed and provides a continuous and controllable elastic downward pressure, the vertical clamping action is automatically triggered by the horizontal clamping process, significantly reducing operation steps, reducing manual intervention, and shortening clamping time.

[0056] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0057] Please see Figures 1-3 As shown, this embodiment provides a technical solution:
[0058] A boring machine quick clamping integrated device includes a placement table 100 and a drive device 200 disposed inside the placement table 100. A pair of clamping mechanisms 300 and a clamping mechanism 400 disposed inside the clamping mechanisms 300 are provided on the top surface of the placement table 100.
[0059] Specifically, the placement platform 100 includes a pair of support plates 110 and a platform 120 that is fixedly connected to the top of the pair of support plates 110 by bolts. A pair of vertically penetrating first sliding grooves 121 are provided at the center of the top surface of the platform 120. A second sliding groove 122 is provided on both sides of the pair of first sliding grooves 121 on the top surface of the platform 120. A pair of plate surface through grooves 123 that are penetrating the bottom surface of the platform 120 are provided on the bottom surface of the second sliding grooves 122.
[0060] Furthermore, the support plate 110 is used to provide a fixed platform for the table 120, and provides a sliding range for the internal structure of the clamping mechanism 300 and the holding mechanism 400 through the first sliding groove 121, the second sliding groove 122 and the plate surface through groove 123 on the top surface of the table 120. This setting is used to provide a stable operating platform for the rapid clamping of workpieces.
[0061] In this embodiment, the drive device 200 includes a motor 210 fixedly connected to the outer wall of the support plate 110 by bolts and a bidirectional lead screw 220 coaxially connected to the output shaft of the motor 210. The other end of the bidirectional lead screw 220 is rotatably connected to the inside of the support plate 110.
[0062] Furthermore, after the motor 210 is started, it can drive the bidirectional lead screw 220 to rotate, so that a pair of clamping mechanisms 300 can move towards each other. This setting, through the single power source of the motor 210, combined with the internal structure of the clamping mechanism 300 and the clamping mechanism 400, completes the rapid clamping of the workpiece.
[0063] Please see Figures 3-5 As shown, in this embodiment, the pressing mechanism 300 includes a transverse frame 310, two symmetrically arranged toothed plates 320, a guide block 340 disposed above the transverse frame 310, and a pressing part 360 disposed inside it. The guide block 340 has a guide groove 341 inside. The driving device 200 drives the pair of transverse frames 310 to move towards each other, causing the guide block 340 to move together.
[0064] Specifically, the pressing mechanism 300 also includes a bracket 330 disposed between the transverse frame 310 and the guide block 340 and a slide bar 350 disposed inside the pressing part 360. The bottom protrusion of the transverse frame 310 is slidably connected to the inside of the first slide groove 121 and threadedly connected to the bidirectional lead screw 220. An abutment block 311 is integrally formed on the inner wall of the transverse frame 310.
[0065] Furthermore, the toothed plate 320 is fixedly connected to the inner wall of the transverse frame 310 by bolts, the bottom end of the bracket 330 is fixedly connected to the top surface of the transverse frame 310 by bolts, and the guide block 340 is snapped and fixed to the top surface of the bracket 330.
[0066] Furthermore, after the bidirectional lead screw 220 rotates, it drives the transverse frame 310 in the clamping mechanism 300 at both ends of the workpiece to move towards each other. The pressing block 311 is used to abut against the internal structure of the clamping mechanism 400. The toothed plate 320 is used to cooperate with the structure in the clamping mechanism 400 to ensure the fixed position of the clamping mechanism 400. The bracket 330 is used to provide a fixed base point for the guide block 340. The slide bar 350 is used to limit the sliding range of the pressing part 360. With this configuration, after the bidirectional lead screw 220 rotates, it can drive the pressing part 360 and the clamping mechanism 400 to move towards the workpiece through the transverse frame 310.
[0067] Please see Figures 3-6 As shown, in this embodiment, the pressing part 360 includes a pressing strip 361, a connecting rod 362 disposed in the outer groove therein, and a pressing block 365 that moves with the pressing strip 361. The guide block 340 moves inward, driving the connecting rod 362 to move along the guide groove 341, so that the pressing strip 361 and the pressing block 365 move down synchronously.
[0068] Specifically, the pressing part 360 also includes a telescopic rod 363 that is engaged between the pressing strip 361 and the pressing block 365, and a first spring 364 that is sleeved on the outside of the telescopic rod 363. The elastic force provided by the first spring 364 is used to push the pressing block 365 to move downward, and the pressing strip 361 is slidably connected to the outside of the slide rod 350.
[0069] Furthermore, when the guide block 340 moves downward in the direction of the pressing part 360, the connecting rod 362 moves along the guide groove 341, which drives the pressure bar 361 to move downward outside the slide bar 350. When the pressure block 365 below the pressure bar 361 comes into contact with the top surface of the workpiece, the continuously moving pressure bar 361 will compress the first spring 364. The increased elastic potential energy of the first spring 364 acts on the surface of the workpiece, improving the stability of the workpiece when it is fixed. This feature is used in the clamping mechanism 400 to complete the pressing operation on the top of the workpiece by cooperating with the pressing part 360 during the clamping process, thereby reducing the step of manually tightening the bolts and speeding up the clamping operation of the workpiece.
[0070] Please see Figures 4-8 As shown, in this embodiment, the clamping mechanism 400 includes a transverse plate 410, a connecting frame 420 snapped onto the outside of the transverse plate 410, a second spring 440 sleeved on the end round rod of the connecting frame 420, and a pair of positioning parts 460. The transverse frame 410 presses against the second spring 440 to move the transverse plate 410 to the outer wall of the workpiece, and then compresses the second spring 440 to move the toothed plate 320 and the guide block 340 inward.
[0071] Specifically, the clamping mechanism 400 also includes a pair of clamping blocks 430 that are fixedly connected to the top surface of the transverse plate 410 by bolts, and a pair of sliders 450 that are welded to the bottom surface of the transverse plate 410. The sliders 450 are slidably connected to the inside of the second slide groove 122 and the plate surface through groove 123. The inside of the sliders 450 is provided with a slot 451 that runs through the left and right sides. The bottom end of the slide rod 350 is fixedly connected to the top surface of the transverse plate 410 by bolts.
[0072] Furthermore, the round rod at the end of the connecting frame 420 is fixedly connected to the outer wall of the transverse plate 410 by bolts, and the inner end of the second spring 440 is welded and fixed to the outer wall of the transverse plate 410. The elastic force provided by the second spring 440 is used to push the clamping mechanism 300 to move outward as a whole.
[0073] Furthermore, when the transverse frame 310 moves, it presses against the second spring 440, causing the transverse plate 410 to move synchronously toward the workpiece. Subsequently, the clamping block 430 on the top surface of the transverse plate 410 contacts the outer wall of the workpiece, while the transverse frame 310, which continues to move inward, continuously compresses the second spring 440 until the pressing block 311 contacts the transverse plate 410, at which point the motor 210 is turned off. During this process, the reaction force provided by the second spring 440 acts on the surface of the workpiece through the clamping block 430. This setting, through the second spring 440, allows the clamping mechanism 300 to continue to move inward after the workpiece clamping is completed, further improving the workpiece clamping effect, while also driving the guide block 340 to allow the pressing part 360 to press down on the workpiece.
[0074] Please see Figures 4-9 As shown, in this embodiment, the positioning part 460 includes a lead screw 463, a pressing frame 464 sleeved on the outside of the lead screw 463, and a rod tooth 465 engaged with the end of the lead screw 463.
[0075] Specifically, the positioning part 460 also includes a base plate 461 for placing the pressing frame 464 and round rods 462 that are snapped onto both ends of the top surface of the base plate 461. The top end of the round rods 462 is snapped onto the bottom surface of the slider 450. The lead screw 463 is rotatably connected to the inside of the slider 450. The pressing frame 464 is slidably connected to the two round rods 462, and the two ends of the pressing frame 464 protrude on both sides of the plate surface through groove 123.
[0076] Furthermore, the toothed plate 320 moves inward, and the meshing rod teeth 465 drive the lead screw 463 to rotate, causing the pressure frame 464 to move upward and fix the transverse plate 410. The base plate 461, in conjunction with the round rod 462, is used to limit the movement range of the pressure frame 464. This setting, when the workpiece is clamped, achieves the fixation of the overall structural position of the clamping mechanism 400 through the cooperation of the toothed plate 320 and the rod teeth 465, thereby ensuring the stability of subsequent processing.
[0077] The present invention also provides a method for quick clamping of a boring machine, using the above-mentioned quick clamping integrated device for a boring machine, comprising the following steps:
[0078] S1. First, place the workpiece to be processed at the center of the table 120 and start the motor 210 to drive the bidirectional lead screw 220 to rotate.
[0079] S2. After the bidirectional lead screw 220 rotates, it drives the transverse frame 310 in the pressing mechanism 300 at both ends of the workpiece to move towards each other. At the same time, the transverse frame 310 presses against the second spring 440, driving the transverse plate 410 to move synchronously towards the workpiece.
[0080] S3. Subsequently, the clamping block 430 on the top surface of the transverse plate 410 abuts against the outer wall of the workpiece, and the transverse frame 310, which continues to move inward, continuously compresses the second spring 440 until the pressing block 311 abuts against the transverse plate 410, and then the motor 210 is turned off.
[0081] S4. During this process, the reaction force provided by the second spring 440 acts on the workpiece surface through the clamping block 430, and during the inward displacement of the toothed plate 320, the meshing rod tooth 465 drives the lead screw 463 to rotate, which drives the pressing frame 464 to move upward, and presses its two ends against the bottom surface of the platform 120, thereby fixing the transverse plate 410.
[0082] S5. At the same time, during the inward displacement of the guide block 340 in the pressing mechanism 300, the connecting rod 362 of the pressing part 360 is driven to move along the guide groove 341, which in turn drives the pressing strip 361 to move downward.
[0083] S6. After the pressure block 365 comes into contact with the top surface of the workpiece, the continuously moving pressure bar 361 will compress the first spring 364, and the increased elastic potential energy through the first spring 364 will act on the surface of the workpiece.
[0084] S7. Subsequently, after the boring machine completes the machining of the workpiece, the motor 210 drives the bidirectional lead screw 220 to rotate in the opposite direction, thereby restoring the positions of the pair of clamping mechanisms 300 and clamping mechanisms 400.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.

6. The boring machine quick clamping integrated device according to claim 5, characterized in that: The top end of the round rod is engaged with the bottom surface of the slider, the lead screw is rotatably connected to the inside of the slider, the pressure frame is slidably connected to the two round rods, and the two ends of the pressure frame protrude on both sides of the through groove on the plate surface.
7. A method for rapid clamping of a boring machine, using the rapid clamping integrated device for a boring machine as described in claim 6, characterized in that, Includes the following steps: S1. First, place the workpiece to be processed in the center of the table and start the motor to drive the bidirectional lead screw to rotate. S2. After the bidirectional lead screw rotates, it drives the transverse frame in the clamping mechanism at both ends of the workpiece to move towards each other. At the same time, the transverse frame presses against the second spring, driving the transverse plate to move synchronously towards the workpiece. S3. Subsequently, the clamping block on the top surface of the transverse plate abuts against the outer wall of the workpiece, while the transverse frame, which continues to move inward, continuously compresses the second spring until the pressing block abuts against the transverse plate, at which point the motor is turned off. S4. During this process, the reaction force provided by the second spring acts on the workpiece surface through the clamping block, and during the inward displacement of the toothed plate, the meshing rod drives the lead screw to rotate, causing the pressure frame to move upward, and pressing its two ends against the bottom surface of the platform, thereby fixing the transverse plate. S5. At the same time, during the inward displacement of the guide block in the pressing mechanism, the connecting rod of the lower pressing part is driven to move along the guide groove, which in turn drives the pressure bar to move downward. S6. After the pressure block comes into contact with the top surface of the workpiece, the continuously moving pressure bar will compress the first spring, and the increased elastic potential energy through the first spring will act on the surface of the workpiece. S7. Subsequently, after the boring machine completes the machining of the workpiece, the motor drives the bidirectional lead screw to rotate in the opposite direction, thereby restoring the positions of the pair of clamping mechanisms and holding mechanisms.
