Description

Technical Field

[0001] This invention relates to the field of workshop work platforms, specifically to a work platform for machining workshops used for the fixed storage of tool chucks. Background Technology

[0002] A work platform refers to equipment installed in a factory workshop. A tool chuck is a tool used to hold cutting tools, typically used in CNC machine tool machining to ensure tool stability and accuracy.

[0003] As attached Figure 1 As shown, the existing tool chuck includes a tapered spool 1', a pull stud 2' disposed on the bottom end face of the tapered spool 1', a protrusion 3' disposed on the top end face of the tapered spool 1', a tool changing groove 4' disposed on the surface of the protrusion 3', two drive grooves 5' symmetrically disposed on the surface of the protrusion 3', a connecting portion 6' disposed on the top end face of the tapered spool 1', a clamping cap 7' disposed on the connecting portion 6', a tool head 8' disposed between the connecting portion 6' and the clamping cap 7', and a tool 9 disposed on the tool head 8'. The work platform is a workshop equipment for fixedly storing the tool chuck.

[0004] However, existing work platforms have the following drawbacks: When workers insert the tool chuck with an inclination deviation not exceeding the preset allowable angle, it is impossible to achieve collision-free guidance, posture self-correction, step-by-step deceleration, low-stress locking, and fully submerged fixed storage of the tool chuck. As a result, it is impossible to avoid damage to the tool 9' or injury to people, and it is impossible to improve the tolerance for worker operation deviations.

[0005] The purpose of this invention is to design a work platform for a machining workshop to address the problems existing in the prior art. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention provides a work platform for machining workshops, which can effectively solve at least one of the problems existing in the prior art.

[0007] The technical solution of this invention is: A work platform for a machining workshop, comprising: A workbench includes a placement base and a plurality of placement holes disposed on the placement base; The guide and damping clamp assembly includes two guide and damping clamp balls that are symmetrically arranged and swing in the placement hole, and a guide and damping clamp driving device disposed between the guide and damping clamp balls and the placement seat. The guide and damping clamp balls swing in the direction of the axis of the placement hole. The slow-fall support assembly includes a slow-fall support plate that is lifted and disposed within the placement hole and located below the two guide and slow-fall clamping balls, and a slow-fall support drive device disposed between the slow-fall support plate and the placement seat. The submersible assembly includes a support plate that is raised and lowered within the placement hole and located below the slow-fall support plate; a first electromagnet located on the top surface of the support plate and cooperating with the slow-fall support plate; a suction plate located on the bottom surface of the support plate; a second electromagnet located on the placement seat, below the suction plate and cooperating with the suction plate; and a compression spring located between the suction plate and the second electromagnet.

[0008] Furthermore, the slow-fall support drive device includes a connecting ring plate that is lifted and disposed within the placement hole and located above and outside the slow-fall support plate, several elastic telescopic rods disposed between the connecting ring plate and the placement seat, and several connecting rods disposed between the connecting ring plate and the slow-fall support plate.

[0009] Furthermore, a lifting and anti-scratch assembly is provided on the placement seat, located inside the placement hole and above the connecting ring plate, and the lifting and anti-scratch assembly cooperates with the connecting ring plate.

[0010] Furthermore, the lifting and anti-scratch assembly includes a third electromagnet disposed in the placement hole and located above the connecting ring plate, and an insulating bracket disposed between the third electromagnet and the placement seat, wherein the third electromagnet cooperates with the connecting ring plate.

[0011] Furthermore, it also includes a wear detection device disposed on the placement base.

[0012] Furthermore, the wear detection device includes a robotic arm mounted on the placement seat and an industrial camera mounted on the robotic arm.

[0013] Furthermore, the guide-and-stop clamp driving device includes a rotating shaft rotatably mounted on the placement seat and located below the guide-and-stop clamp ball, a swing rod disposed between the rotating shaft and the guide-and-stop clamp ball, two swing torsion springs disposed between the rotating shaft and the placement seat and located on both sides of the swing rod, and a limiting rope disposed between the swing rod and the placement seat.

[0014] Furthermore, a conformal adaptive rolling contact device is provided between the swing rod and the guide ball.

[0015] Furthermore, the conformal adaptive roller contact device includes a connecting seat disposed on the swing rod and a conformal adaptive roller contact groove formed on the connecting seat, wherein the guide ball is movably connected within the conformal adaptive roller contact groove.

[0016] Therefore, the present invention provides the following effects and / or advantages: 1) After the worker holds the clamp cap and inserts the tool chuck into the placement hole in the predetermined orientation, the two guide balls apply a symmetrical and gradually increasing radial force to the conical clamp shaft. This guides the tool chuck to fall vertically along the axis of the placement hole and gradually slows down its falling speed after it is inserted into the placement hole. This counteracts the rigid collision or jamming between the tool chuck and the upper edge of the placement hole caused by the worker's insertion angle deviation after the tool chuck is inserted into the placement hole with an inclination deviation not exceeding the preset allowable angle. This actively corrects the posture and decelerates the falling of the tool chuck after it is inserted into the placement hole, so that the tool chuck falls onto the slow-fall support plate in a vertical, stable and gentle state. After the tool chuck falls onto the slow-fall support plate, the slow-fall support drive device provides a buffer to absorb the remaining kinetic energy of the tool chuck, further slowing its descent speed and allowing it to continue falling vertically along the placement hole axis. This results in a smooth descent of the tool chuck with the chuck cap positioned within the placement hole. The guide ball smoothly enters the drive groove and applies a radial force to the protrusion. In turn, the tool chuck is fixed in place with the chuck cap positioned within the placement hole through the coordinated action of the guide ball and the slow-fall support assembly. Without the need for external power or manual secondary adjustment, the tool chuck achieves collision-free guidance, step-by-step deceleration, posture self-correction, and low-stress locking, significantly improving the stability of the placement process and the tolerance to operational deviations. After the guide-and-slow-drop support assembly and the slow-fall support assembly work together to fix the tool chuck and the chuck cap is located in the placement hole, the first electromagnet and the second electromagnet are simultaneously energized to drive the slow-fall support plate to descend, so that the tool chuck falls and the tool is located in the placement hole. The guide-and-slow-drop support ball moves upward relative to the tool chuck in the drive groove and abuts against the protrusion and applies a radial force to the protrusion. Then, with the coordinated cooperation of the guide-and-slow-drop support assembly, the slow-fall support assembly and the clearance-and-sink assembly, the tool chuck is fixed and the tool is located in the placement hole. This completely and stably fixes the tool chuck in the placement hole without exposing it, preventing the tool from being loosened in the placement hole due to accidental collision, and preventing the tool from being damaged by accidental collision or causing scratches to the worker.

[0017] In summary, when a worker inserts the tool chuck with an inclination deviation not exceeding the preset allowable angle, the tool chuck can be guided without collision, self-corrected in posture, decelerated step by step, locked with low stress, and stored in a completely submerged manner. This can prevent tool damage or injury and increase tolerance to worker operational deviations.

[0018] 2) When the worker needs to remove the tool chuck from the placement hole, the sinking assembly first releases the constraint on the slow-fall support plate, and then the lifting and anti-scratch assembly drives the slow-fall support plate to rise. This allows the guide and slow-fall clamping balls to move downward relative to the tool chuck in the drive groove and apply radial force to the tapered chuck shaft. This causes the tool chuck to rise smoothly and the chuck cap to be exposed outside the placement hole, allowing the worker to hold the chuck cap and remove the tool chuck vertically. During the vertical removal process, the radial force applied by the two guide and slow-fall clamping balls to the tapered chuck shaft can reduce resistance and prevent the tool from scratching the worker, achieving a smooth, easy, and safe removal operation.

[0019] 3) The wear detection device is used to detect the wear of the tool when the lifting and anti-scratch assembly drives the slow-fall support plate to rise and the clamp cap is exposed outside the placement hole. This allows the worker to make work decisions directly based on the detected tool wear when removing the tool chuck from the placement hole, thereby significantly improving production continuity and tool chuck management efficiency, and reducing waiting and transfer time.

[0020] 4) The conformal adaptive rolling contact device is used to make the guide and slowing clamping ball adaptively adjust its contact posture when it contacts the tool chuck, so as to ensure that the tool chuck is guided to fall or rise vertically along the axis of the placement hole; the conformal adaptive rolling contact device is used to convert the sliding friction between the guide and slowing clamping ball and the tool chuck into rolling friction during the falling or rising process of the tool chuck, thereby significantly reducing the motion resistance, preventing the tool chuck from being scratched, and achieving a smooth, fluid and easy operation for the worker when taking it out.

[0021] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0029] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-5 A work platform for a machining workshop, comprising: The workbench 1 includes a placement base 11 and a plurality of placement holes 12 disposed on the placement base 11; The guide and damping clamp assembly 2 includes two guide and damping clamp balls 21 that are symmetrically arranged and swing within the placement hole 12, and a guide and damping clamp driving device 22 disposed between the guide and damping clamp balls 21 and the placement seat 11. The guide and damping clamp balls 21 swing in the direction of the axis of the placement hole 12. The slow-fall support assembly 3 includes a slow-fall support plate 31 that is lifted and disposed within the placement hole 12 and located below the two guide slow-fall clamping balls 21, and a slow-fall support drive device 32 disposed between the slow-fall support plate 31 and the placement seat 11. The submerged assembly 4 includes a support plate 41 that is raised and lowered within the placement hole 12 and located below the slow-fall support plate 31; a first electromagnet 42 located on the top surface of the support plate 41 and cooperating with the slow-fall support plate 31; a suction plate 43 located on the bottom surface of the support plate 41; a second electromagnet 44 located on the placement seat 11, located below the suction plate 43 and cooperating with the suction plate 43; and a compression spring 45 located between the suction plate 43 and the second electromagnet 44.

[0030] After the worker holds the clamp cap 7' and inserts the tool chuck into the placement hole 12 in the predetermined orientation, the two guide and slow-release clamping balls 21 apply a symmetrical and gradually increasing radial force to the conical clamping shaft 1'. This guides the tool chuck to fall vertically along the axis of the placement hole 12 after it is inserted into the placement hole 12, and the falling speed gradually decreases. This counteracts the rigid collision or jamming between the tool chuck and the upper edge of the placement hole 12 caused by the worker's insertion angle deviation after the tool chuck is inserted into the placement hole 12 with an inclination deviation not exceeding the preset allowable angle. This actively corrects the posture and decelerates the falling of the tool chuck after it is inserted into the placement hole 12, so that the tool chuck falls onto the slow-fall support plate 31 in a vertical, stable and gentle state. After the tool chuck falls onto the slow-fall support plate 31, the slow-fall support drive device 32 provides a buffer to the slow-fall support plate 31 to absorb the remaining kinetic energy of the tool chuck, thereby further slowing down the falling speed of the tool chuck and allowing it to continue falling vertically along the axis of the placement hole 12. This results in the tool chuck falling smoothly with the chuck cap 7' located inside the placement hole 12, and the guide and slow-fall abutment ball 21 smoothly entering the drive groove 5' and applying a radial force to the protrusion 3'. Then, with the coordinated cooperation of the guide and slow-fall abutment assembly 2 and the slow-fall support assembly 3, the tool chuck is fixed and the chuck cap 7' is located inside the placement hole 12. Without the need for external power or manual secondary adjustment, the tool chuck achieves collision-free guidance, step-by-step deceleration, posture self-correction, and low-stress locking, significantly improving the stability of the placement process and the tolerance to operational deviations. After the guide-and-slow-fall clamping assembly 2 and the slow-fall support assembly 3 work together to fix the tool chuck and the chuck cap 7' is located in the placement hole 12, the first electromagnet 42 and the second electromagnet 44 are simultaneously energized to drive the slow-fall support plate 31 to descend, so that the tool chuck falls and the tool 9' is located in the placement hole 12. The guide-and-slow-fall clamping ball 21 moves upward relative to the tool chuck in the drive groove 5' and abuts against the protrusion 3' and applies a radial force to the protrusion 3'. Then, with the coordinated cooperation of the guide-and-slow-fall clamping assembly 2, the slow-fall support assembly 3, and the clearance and full-sinking assembly 4, the tool chuck is fixed and the tool 9' is located in the placement hole 12. This completely and stably fixes the tool chuck in the placement hole 12 without exposing it, preventing the tool 9' from being loosened in the placement hole 12 due to accidental collision, and preventing the tool 9' from being damaged or scratched by the worker due to accidental collision.

[0031] The slow-fall support drive device 32 includes a connecting ring plate 321 that is raised and lowered within the placement hole 12 and located above and outside the slow-fall support plate 31, several elastic telescopic rods 322 disposed between the connecting ring plate 321 and the placement seat 11, and several connecting rods 323 disposed between the connecting ring plate 321 and the slow-fall support plate 31.

[0032] A lifting and outgoing anti-scratch component 5 is provided on the placement seat 11, located inside the placement hole 12 and above the connecting ring plate 321. The lifting and outgoing anti-scratch component 5 cooperates with the connecting ring plate 321. When the worker needs to remove the tool chuck from the placement hole 12, the sinking assembly 4 first releases the constraint on the slow-falling support plate 31, and then the lifting and anti-scratch assembly 5 drives the slow-falling support plate 31 to rise. This allows the guide and slow-falling clamping balls 21 to move downward relative to the tool chuck in the drive groove 5' and apply a radial force to the tapered chuck shaft 1'. This causes the tool chuck to rise smoothly and the clamp cap 7' to be exposed outside the placement hole 12, allowing the worker to hold the clamp cap 7' and remove the tool chuck vertically. During the vertical removal process, the radial force applied by the two guide and slow-falling clamping balls 21 to the tapered chuck shaft 1' reduces resistance and prevents the tool 9' from scratching the worker, achieving a smooth, easy, and safe removal operation.

[0033] The lifting and anti-scratch assembly 5 includes a third electromagnet 51 disposed in the placement hole 12 and above the connecting ring plate 321, and an insulating bracket 52 disposed between the third electromagnet 51 and the placement seat 11. The third electromagnet 51 cooperates with the connecting ring plate 321.

[0034] It also includes a wear detection device 6 disposed on the placement seat 11.

[0035] The wear detection device 6 is used to detect the wear of the tool 9' when the lifting and anti-scratch assembly 5 drives the slow-fall support plate 31 to rise and the clamp cap 7' is exposed outside the placement hole 12. This allows the worker to make work decisions directly based on the detected wear of the tool 9' when removing the tool chuck from the placement hole 12, thereby significantly improving production continuity and tool chuck management efficiency, and reducing waiting and transfer time.

[0036] The wear detection device 6 includes a robotic arm 61 mounted on the placement seat 11 and an industrial camera 62 mounted on the robotic arm 61.

[0037] The guide-and-release clamping drive device 22 includes a rotating shaft 221 rotatably mounted on the placement seat 11 and located below the guide-and-release clamping ball 21, a swing rod 222 disposed between the rotating shaft 221 and the guide-and-release clamping ball 21, two swing torsion springs 223 disposed between the rotating shaft 221 and the placement seat 11 and located on both sides of the swing rod 222, and a limiting rope 224 disposed between the swing rod 222 and the placement seat 11.

[0038] A conformal adaptive rolling contact device 7 is provided between the swing rod 222 and the guide and slow clamping ball 21; The conformal adaptive rolling contact device 7 is used to make the guide and slowing clamping ball 21 adaptively adjust the contact posture when it contacts the tool chuck, so as to ensure that the tool chuck is guided to fall or rise vertically along the axis of the placement hole 12. The conformal adaptive rolling contact device 7 is used to convert the sliding friction between the guide ball 21 and the tool chuck into rolling friction during the falling or rising process of the tool chuck, thereby significantly reducing the motion resistance, preventing the tool chuck from being scratched, and achieving a smooth, fluid, and easy operation for the worker when taking it out.

[0039] The conformal adaptive roller contact device 7 includes a connecting seat 71 disposed on the swing rod 222 and a conformal adaptive roller contact groove 72 opened on the connecting seat 71, wherein the guide and slow clamping ball 21 is movably connected in the conformal adaptive roller contact groove 72.
