Description

Technical Field

[0001] The present invention relates to the technical field of workpiece clamping, in particular to a boring machine rapid clamping integrated device and method thereof. Background Art

[0002] The clamping device of a boring machine is a key device 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 processing to withstand the cutting force and achieve the required processing accuracy. The device must have sufficient rigidity, precise positioning reference and convenient operability to ensure that the position, roundness, dimensional accuracy and surface quality of the bored hole meet the process requirements.

[0003] The patent with 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 grooves 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 cross frame is provided between the two adjustable horizontal clamping frames, which can limit and fix the workpiece in the vertical direction, thereby improving the adaptability of the boring machine in clamping and fixing the workpiece.

[0004] However, traditional fixtures require manual adjustment of the clamping mechanisms on both sides and lack a self-locking function. After horizontal clamping, additional manual locking is required to prevent displacement, which significantly prolongs the clamping time. The clamping process lacks elastic buffering, and thin-walled or precision workpieces are easily crushed and deformed due to rigid contact. The top clamping of the workpiece requires independent operation, such as manually tightening the pressure plate bolts, which cannot be linked with the horizontal clamping. This not only increases the intensity of manual intervention, but also causes uneven clamping or overpressure risks due to inaccurate pressure control. These fragmented multi-step operation modes force clamping time to occupy an excessively high proportion of the processing cycle.

[0005] In view of this, we propose a boring machine quick clamping integrated device and method. Summary of the Invention

[0006] The object of the present invention is to provide a boring machine quick clamping integrated device and method thereof to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: A fast clamping integrated device for a boring machine comprises a placing table and a driving device arranged inside the placing table, wherein a pair of pressing mechanisms and a clamping mechanism arranged inside the pressing mechanisms are provided on the top surface of the placing table; The clamping mechanism includes a transverse frame, two symmetrically arranged tooth plates, a guide block arranged above the transverse frame, and a downward pressing portion arranged on the inner side thereof, wherein a guide groove is provided inside the guide block; This setting drives a pair of transverse frames to move toward each other, driving the guide blocks to move together; The pressing portion includes a pressing strip, a connecting rod arranged in a groove outside the pressing strip, and a pressing block moving with the pressing strip; This setting moves the guide block inward, driving the connecting rod to move along the guide groove, allowing the pressure strip and the pressure block to move downward synchronously; The clamping mechanism includes a transverse plate, a connecting frame clamped on the outer side of the transverse plate, a second spring sleeved on the outer side of the round rod at the end of the connecting frame, and a pair of positioning parts; In this arrangement, the transverse frame presses the second spring to drive the transverse plate to the outer wall of the workpiece, and then compresses the second spring to drive the tooth plate and the guide block to move inward; The positioning part includes a screw rod, a pressing frame sleeved on the outside of the screw rod, and a rod tooth clamped on the end of the screw rod; In this configuration, the toothed plate moves inward, and the meshing rod teeth drive the screw rod to rotate, thereby driving the pressure frame to move upward to fix the transverse plate.

[0008] In the technical solution of the present invention, the placing table includes a pair of support plates and a table plate fixedly connected to the top of the pair of support plates by bolts, a pair of first slide grooves passing through the top and bottom are opened at the center of the top surface of the table plate, and second slide grooves are opened on both sides of the pair of first slide grooves on the top surface of the table plate, and a pair of plate surface grooves passing through the bottom surface of the table plate are opened on the bottom surface of the second slide groove.

[0009] This setting is used to provide a stable operating platform for quick clamping of workpieces.

[0010] 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 screw coaxially connected to the output shaft of the motor, and the other end of the bidirectional screw is rotatably connected to the inside of the support plate.

[0011] This arrangement uses a single power source of the motor in conjunction with the internal structure of the clamping mechanism and the clamping mechanism to achieve rapid clamping of the workpiece.

[0012] In the technical solution of the present invention, the clamping mechanism also includes a bracket arranged between the transverse frame and the guide block and a sliding rod arranged inside the lower pressure part. The bottom protrusion of the transverse frame is slidably connected to the inside of the first slide groove and is threadedly connected to the bidirectional screw rod. A pressure block is integrally formed on the inner wall of the transverse frame.

[0013] In the technical solution of the present invention, the tooth 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 clamped and fixed to the top surface of the bracket.

[0014] After the bidirectional screw is rotated, the downward pressing portion and the clamping mechanism can be driven to move toward the workpiece through the transverse frame.

[0015] In the technical solution of the present invention, the downward pressure part also includes a telescopic rod clamped between the pressure strip and the pressure 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 pressure block to move downward, and the pressure strip is slidably connected to the outside of the sliding rod.

[0016] This setting completes the downward pressure operation on the top of the workpiece through the guide block and the downward pressure part during the process of the clamping mechanism clamping the workpiece, thereby reducing the steps of manually tightening the bolts and speeding up the clamping operation of the workpiece.

[0017] In the technical solution of the present invention, the clamping mechanism also 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. A slot that passes through the left and right is opened inside the slider, and the bottom end of the slide rod is fixedly connected to the top surface of the transverse plate by bolts.

[0018] 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 clamping mechanism to move outward as a whole.

[0019] The above arrangement enables the clamping mechanism to continue to move inward after completing the workpiece clamping through the second spring, thereby further improving the workpiece clamping effect, and can also drive the guide block to allow the pressing part to complete the downward pressure on the workpiece.

[0020] In the technical solution of the present invention, the positioning part also includes a base plate for placing the pressure frame and round rods clamped at both ends of the top surface of the base plate, the top end of the round rods is clamped on the bottom surface of the slider, the screw rod is rotatably connected to the inside of the slider, the pressure frame is slidably connected to the two round rods and the protrusions at both ends of the pressure frame are located on both sides of the through groove on the plate surface.

[0021] When the workpiece is clamped, this setting fixes the overall structural position of the clamping mechanism through the cooperation between the tooth plate and the rod teeth, thereby ensuring the stability of subsequent processing.

[0022] On the other hand, the present invention also provides a method for rapid clamping of a boring machine, using the above-mentioned rapid clamping integrated device for a boring machine, comprising the following steps: S1. First, place the workpiece to be processed at the center of the table, and start the motor to drive the bidirectional screw to rotate; S2. After the bidirectional screw rotates, it drives the transverse frames in the clamping mechanism at the left and right ends of the workpiece to move toward each other. At the same time, the transverse frame presses the second spring, driving the transverse plate to move synchronously toward the workpiece. S3. Subsequently, the clamping block on the top surface of the transverse plate contacts the outer wall of the workpiece, and the transverse frame continues to move inward, continuously compressing the second spring until the pressing block contacts the transverse plate, and then the motor is turned off; S4. During this process, the reaction force provided by the second spring acts on the surface of the workpiece through the clamping block, and during the inward displacement of the toothed plate, the meshing rod teeth drive the screw to rotate, driving the pressing frame to move upward, pressing the protrusions at both ends of the frame against the bottom surface of the table, 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 pressing portion is driven to move along the guide groove, driving the pressing strip to move downward; S6. After the pressing block contacts the top surface of the workpiece, the pressing strip that continues to move downward compresses the first spring, and the elastic potential energy increased by the first spring acts on the surface of the workpiece; S7. Subsequently, after the boring machine completes the processing of the workpiece, the motor is driven to drive the bidirectional lead screw to rotate in the opposite direction, thereby restoring the positions of the pair of clamping mechanisms and the clamping mechanism.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. This boring machine's integrated rapid clamping device and method uses a bidirectional lead screw to synchronously drive the two side transverse frames to move toward each other, combined with the elastic buffering of the second spring to achieve flexible lateral clamping of the workpiece, avoiding damage to the workpiece due to rigid impact; at the same time, the linkage structure of the tooth plate and the meshing rod teeth automatically triggers the pressure frame to move up and lock the bottom surface of the table after the transverse frame moves into place, forming a rigid self-locking. Driven by a single motor, it completes the adaptive clamping and position locking of the workpiece in one go, greatly improving the clamping efficiency and stability.

[0024] 2. This boring machine's integrated rapid clamping device and method uses the inward displacement of the transverse frame to synchronously move the guide block, forcing the connecting rod to slide along the inclined guide groove, converting horizontal movement into vertical downward pressure on the pressure bar. When the pressure block contacts the workpiece, the first spring is compressed and provides continuous and controllable elastic downward force. The vertical clamping action is automatically triggered by the horizontal clamping process, significantly reducing the number of operating steps, alleviating manual intervention, and shortening clamping time.

DETAILED DESCRIPTION

[0026] The following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 3 As shown, this embodiment provides a technical solution: A fast clamping integrated device for a boring machine includes a placement table 100 and a driving device 200 arranged inside the placement table 100. A pair of clamping mechanisms 300 and a clamping mechanism 400 arranged inside the clamping mechanism 300 are provided on the top surface of the placement table 100.

[0028] Specifically, the placement table 100 includes a pair of support plates 110 and a table plate 120 fixedly connected to the top of the pair of support plates 110 by bolts. A pair of first slide grooves 121 that pass through the top and bottom are opened at the center of the top surface of the table plate 120. Second slide grooves 122 are opened on both sides of the pair of first slide grooves 121 on the top surface of the table plate 120. A pair of plate surface grooves 123 that pass through the bottom surface of the table plate 120 are opened on the bottom surface of the second slide grooves 122.

[0029] Furthermore, the support plate 110 is used to provide a fixed platform for the table 120, and provides a sliding area for the internal structure of the clamping mechanism 300 and the clamping mechanism 400 through the first slide groove 121, the second slide groove 122 and the plate surface groove 123 on the top surface of the table 120. This setting is used to provide a stable operating platform for rapid clamping of workpieces.

[0030] In this embodiment, the driving device 200 includes a motor 210 fixedly connected to the outer wall of the support plate 110 by bolts and a bidirectional screw rod 220 coaxially connected to the output shaft of the motor 210, and the other end of the bidirectional screw rod 220 is rotatably connected to the inside of the support plate 110.

[0031] Furthermore, after the motor 210 is started, it can drive the bidirectional screw rod 220 to rotate, allowing a pair of clamping mechanisms 300 to move toward each other. This setting uses the single power source of the motor 210, combined with the internal structure of the clamping mechanism 300 and the clamping mechanism 400, to complete the rapid clamping of the workpiece.

[0032] See also Figure 3-Figure 5 As shown, in this embodiment, the clamping mechanism 300 includes a transverse frame 310, two symmetrically arranged tooth plates 320, a guide block 340 arranged above the transverse frame 310, and a lower pressure portion 360 arranged on the inner side thereof. A guide groove 341 is provided inside the guide block 340, and the driving device 200 drives a pair of transverse frames 310 to move toward each other, driving the guide blocks 340 to move together.

[0033] Specifically, the clamping mechanism 300 also includes a bracket 330 arranged between the transverse frame 310 and the guide block 340 and a slide rod 350 arranged inside the lower pressure part 360. The bottom protrusion of the transverse frame 310 is slidably connected to the inside of the first slide groove 121 and is threadedly connected to the bidirectional screw rod 220. A pressure block 311 is integrally formed on the inner wall of the transverse frame 310.

[0034] Furthermore, the tooth 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 clamped and fixed to the top surface of the bracket 330.

[0035] Furthermore, after the bidirectional screw rod 220 rotates, it drives the transverse frame 310 in the clamping mechanism 300 at the left and right ends of the workpiece to move toward each other, and the pressure block 311 is used to interfere with the internal structure of the clamping mechanism 400. The tooth 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, and the slide rod 350 is used to limit the sliding range of the lower pressure part 360. After the bidirectional screw rod 220 rotates, this setting can drive the lower pressure part 360 and the clamping mechanism 400 to move toward the workpiece through the transverse frame 310.

[0036] See also Figure 3-Figure 6 As shown, in this embodiment, the pressing portion 360 includes a pressure strip 361, a connecting rod 362 arranged in a groove on its outer side, and a pressure block 365 that moves with the pressure strip 361. The guide block 340 moves inward, driving the connecting rod 362 to move along the guide groove 341, allowing the pressure strip 361 and the pressure block 365 to move downward synchronously.

[0037] Specifically, the downward pressing portion 360 also includes a telescopic rod 363 clamped between the pressure strip 361 and the pressure block 365 and a first spring 364 sleeved on the outside of the telescopic rod 363. The elastic force provided by the first spring 364 is used to push the pressure block 365 to move downward, and the pressure strip 361 is slidably connected to the outside of the sliding rod 350.

[0038] Furthermore, when the guide block 340 is displaced toward the downward pressing portion 360, the connecting rod 362 moves along the guide groove 341, driving the pressure strip 361 to move downward on the outside of the slide bar 350. When the pressure block 365 below the pressure strip 361 collides with the top surface of the workpiece, the pressure strip 361 that continues to move downward will compress the first spring 364, and the elastic potential energy increased by the first spring 364 acts on the surface of the workpiece, thereby improving the stability of the workpiece when it is fixed. This setting is set in the process of the clamping mechanism 400 completing the clamping of the workpiece. The guide block 340 cooperates with the downward pressing portion 360 to complete the downward pressing operation on the top of the workpiece, thereby reducing the steps of manually tightening the bolts and speeding up the clamping operation of the workpiece.

[0039] See also Figure 4-Figure 8 As shown, in this embodiment, the clamping mechanism 400 includes a transverse plate 410, a connecting frame 420 clamped on the outside of the transverse plate 410, a second spring 440 sleeved on the outside of the round rod at the end of the connecting frame 420, and a pair of positioning parts 460. The transverse frame 310 presses the second spring 440 to drive the transverse plate 410 to move to the outer wall of the workpiece, and then compresses the second spring 440 to drive the tooth plate 320 and the guide block 340 to move inward.

[0040] Specifically, the clamping mechanism 400 also includes a pair of clamping blocks 430 fixedly connected to the top surface of the transverse plate 410 by bolts and a pair of sliders 450 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. A slot 451 is provided inside the slider 450 that passes 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.

[0041] 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.

[0042] Furthermore, when the transverse frame 310 moves, the transverse frame 310 presses against the second spring 440, driving 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, and the transverse frame 310 continues to move inward, continuously compressing the second spring 440 until the pressing block 311 contacts the transverse plate 410, and then 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 allows the clamping mechanism 300 to continue to move inward after the workpiece is clamped, thereby further improving the clamping effect on the workpiece, and can also drive the guide block 340 to allow the pressing part 360 to complete the downward pressure on the workpiece.

[0043] See also Figure 4-Figure 9 As shown, in this embodiment, the positioning portion 460 includes a screw rod 463 , a pressing frame 464 sleeved on the outside of the screw rod 463 , and a rod tooth 465 clamped on the end of the screw rod 463 .

[0044] Specifically, the positioning portion 460 also includes a base plate 461 on which the pressure frame 464 is placed and round rods 462 clamped at both ends of the top surface of the base plate 461. The top end of the round rod 462 is clamped on the bottom surface of the slider 450, and the screw rod 463 is rotatably connected to the inside of the slider 450. The pressure frame 464 is slidably connected to the two round rods 462, and the protrusions at both ends of the pressure frame 464 are located on both sides of the plate surface groove 123.

[0045] Furthermore, the tooth plate 320 moves inward, and the meshing rod teeth 465 drives the screw 463 to rotate, driving the pressure frame 464 to move upward to fix the transverse plate 410, and the bottom plate 461 cooperates with the round rod 462 to limit the moving range of the pressure frame 464. When this setting completes the clamping of the workpiece, the overall structural position of the clamping mechanism 400 is fixed through the cooperation between the tooth plate 320 and the rod teeth 465, thereby ensuring the stability of subsequent processing.

[0046] The present invention also provides a method for rapid clamping of a boring machine, using the above-mentioned rapid clamping integrated device for a boring machine, comprising the following steps: S1. First, place the workpiece to be processed at the center of the platen 120, and start the motor 210 to drive the bidirectional screw 220 to rotate; S2. After the bidirectional screw 220 rotates, it drives the transverse frames 310 in the clamping mechanism 300 at the left and right ends of the workpiece to move toward each other. At the same time, the transverse frame 310 presses the second spring 440, driving the transverse plate 410 to move synchronously toward the workpiece. S3. Subsequently, the clamping block 430 on the top surface of the transverse plate 410 contacts the outer wall of the workpiece, and the transverse frame 310 continues to move inward, continuously compressing the second spring 440 until the pressing block 311 contacts the transverse plate 410, and then the motor 210 is turned off. S4. During this process, the reaction force provided by the second spring 440 acts on the surface of the workpiece through the clamping block 430. During the inward displacement of the tooth plate 320, the meshing rod teeth 465 drive the screw rod 463 to rotate, driving the pressing frame 464 to move upward, pressing the protrusions at both ends of the frame against the bottom surface of the table 120, thereby fixing the transverse plate 410. 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 portion 360 is driven to move along the guide groove 341, driving the pressing bar 361 to move downward; S6. After the pressing block 365 contacts the top surface of the workpiece, the pressing strip 361 that continues to move downward compresses the first spring 364, and the elastic potential energy increased by the first spring 364 acts on the surface of the workpiece; S7. Subsequently, after the boring machine completes the processing of the workpiece, the motor 210 is driven to drive the bidirectional screw rod 220 to rotate in the opposite direction, thereby restoring the positions of the pair of pressing mechanisms 300 and the clamping mechanism 400.

After the bidirectional screw rotates, it drives the transverse frames in the clamping mechanism at the left and right ends of the workpiece to move toward each other. At the same time, the transverse frame presses the second spring, driving the transverse plate to move synchronously toward the workpiece. S3. Subsequently, the clamping block on the top surface of the transverse plate contacts the outer wall of the workpiece, and the transverse frame continues to move inward, continuously compressing the second spring until the pressing block contacts the transverse plate, and then the motor is turned off; S4. During this process, the reaction force provided by the second spring acts on the surface of the workpiece through the clamping block, and during the inward displacement of the toothed plate, the meshing rod teeth drive the screw to rotate, driving the pressing frame to move upward, pressing the protrusions at both ends of the frame against the bottom surface of the table, 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 pressing portion is driven to move along the guide groove, driving the pressing strip to move downward; S6. After the pressing block contacts the top surface of the workpiece, the pressing strip that continues to move downward compresses the first spring, and the elastic potential energy increased by the first spring acts on the surface of the workpiece; S7. Subsequently, after the boring machine completes the processing of the workpiece, the motor is driven to drive the bidirectional lead screw to rotate in the opposite direction, thereby restoring the positions of the pair of clamping mechanisms and the clamping mechanism.
