Description

Technical Field

[0001] This invention relates to the field of mechanical equipment support technology, and in particular to a stepped pad mechanism with a rapid leveling function. Background Technology

[0002] In the installation of industrial equipment, construction, and debugging of precision equipment, shims are often used to adjust the height and level of equipment or structures. Traditional stepped shims mostly use a method of stacking shims of fixed height for coarse adjustment, which has problems such as cumbersome leveling steps and insufficient adjustment accuracy. Although some shims with wedge-shaped fine-tuning structures can achieve fine adjustment within a small range, in actual use, due to the lack of effective guiding constraints between the base and the stepped shims, the shims are prone to lateral displacement, misalignment, and swaying, resulting in unstable leveling process, affecting the final support accuracy, and failing to meet the requirements of fast, stable, and high-precision leveling.

[0003] Therefore, a new stepped pad mechanism with rapid leveling function needs to be designed to overcome the above-mentioned technical defects. Summary of the Invention

[0004] The purpose of this invention is to provide a stepped pad mechanism with a quick leveling function, which can quickly level and smoothly lift the pad, is simple to operate, and is convenient for on-site installation, debugging and daily maintenance.

[0005] To achieve the above objectives, the present invention provides a stepped pad mechanism with a rapid leveling function, comprising: a base, a sliding component, a first support seat, a second support seat, and a driving component. The sliding component is mounted on the base, and the first and second support seats are both slidably mounted on the sliding component. The first support seat has a first slope, and the second support seat has a second slope. The first and second support seats are symmetrically distributed. The driving component is mounted on the base and connected to the first and second support seats. A pad is placed between the first slope of the first support seat and the second slope of the second support seat. The driving component is used to drive the first and second support seats to move in a direction that moves closer to or further away from each other.

[0006] Preferably, the sliding component includes a guide rail and two sliders. The guide rail is mounted on the base, one slider is mounted on a first support and slidably connected to the guide rail, and the other slider is mounted on a second support and slidably connected to the guide rail.

[0007] Preferably, the first support base includes a first support frame, a first wedge block, and a first connecting block. The first support frame has first mounting grooves at both ends. The slider is installed in the first mounting groove. The first support frame is slidably connected to the guide rail through the slider. The first ramp is set on the first wedge block. The first wedge block is installed on the top of the middle section of the first support frame. The first connecting block is installed on the bottom of the middle section of the first support frame and connected to the driving component.

[0008] Preferably, the second support base includes a second support frame, a second wedge block, and a second connecting block. The second support frame has second mounting grooves at both ends. The slider is installed in the second mounting groove. The second support frame is slidably connected to the guide rail through the slider. The second ramp is set on the second wedge block. The second wedge block is installed on the top of the middle section of the second support frame. The second connecting block is installed on the bottom of the middle section of the second support frame and connected to the driving component.

[0009] Preferably, the driving component includes a bidirectional ball screw, a first nut seat, and a second nut seat. The bidirectional ball screw is rotatably mounted on the base via a mounting seat and includes a first screw portion and a second screw portion coaxially connected to the first screw portion. The thread direction of the first screw portion is opposite to that of the second screw portion. The first nut seat is threadedly connected to the first screw portion and fixed to a first connecting block. The second nut seat is threadedly connected to the second screw portion and fixed to a second connecting block.

[0010] Preferably, the drive component further includes a gear plate and a locking assembly. The gear plate is connected to one end of a bidirectional ball screw, and the locking assembly is mounted on a mounting base and distributed close to the gear plate. The locking assembly is used to restrict the rotation of the gear plate.

[0011] Preferably, the locking assembly includes a mounting rod, an elastic element, a mounting plate, and a pin. The mounting rod is slidably mounted on the mounting base. The elastic element is installed in a slot in the mounting base, with one end of the elastic element connected to the mounting base and the other end connected to the mounting plate. The mounting plate is connected to both ends of the mounting rod and distributed close to the gear plate. A locking block is protruded on the side of the mounting plate near the gear plate. The pin is detachably mounted on the mounting base and located between the gear plate and the locking block.

[0012] Preferably, the gear disc is provided with a starter cylinder.

[0013] Preferably, the stepped pad mechanism with quick leveling function further includes an anti-detachment guide mechanism, which includes a receiving cylinder, an anti-detachment plate, and a locking buckle. A guide post is formed by the bottom protrusion of the pad, and the guide post is movably inserted into the receiving cylinder. The receiving cylinder is installed on the base. The anti-detachment plate has an anti-detachment opening, and the anti-detachment plate is installed on the base with the anti-detachment opening facing upward. The locking buckle is installed on the pad and slidably sleeved on the anti-detachment opening.

[0014] Compared with existing technologies, the advantages are: 1) It can be quickly leveled and the pad can be raised smoothly. The operation is simple and it is convenient for on-site installation, debugging and daily maintenance. It can ensure that the first support and the second support are evenly stressed on both sides without deviation or tilting.

[0015] 2) By changing the direction of the bidirectional ball screw, the first support seat and the second support seat can be driven to move closer to or further away from each other. This eliminates the need for dual drive and transmission, simplifies the overall transmission structure, reduces power and transmission components, and lowers equipment manufacturing costs and assembly difficulty.

[0016] 3) When the installation height of the pads on the first and second support seats is adjusted, the pin is removed from the mounting seat. The locking block on the mounting plate engages with the gear plate to limit the gear plate. After adjustment, mechanical self-locking can be achieved, and the position of the pad can remain unchanged and is not easy to shift.

[0017] Other features and advantages of the invention will be set forth in the following description, and in part will be apparent from the description, or may be learned by practice of the invention. The features and advantages of the invention may be realized and obtained by means of the elements and combinations specifically pointed out in the appended claims. Attached Figure Description

[0029] Please see Figures 1 to 5 The present invention provides a stepped pad mechanism with a rapid leveling function, comprising: a base 1, a sliding component 2, a first support 3, a second support 4, and a driving component 5.

[0030] The sliding component 2 is mounted on the base 1. The first support seat 3 and the second support seat 4 are both slidably mounted on the sliding component 2. The first support seat 3 has a first ramp 30, and the second support seat 4 has a second ramp 40. The first support seat 3 and the second support seat 4 are symmetrically distributed. The driving component 5 is mounted on the base 1 and connected to the first support seat 3 and the second support seat 4. The driving component 5 is used to drive the first support seat 3 and the second support seat 4 to move in a direction that is closer to or further away from each other.

[0031] In use, the pad 8 is placed between the first ramp 30 of the first support base 3 and the second ramp 40 of the second support base 4. When the driving component 5 drives the first support base 3 and the second support base 4 to move closer to each other, the first ramp 30 and the second ramp 40 squeeze each other to drive the horizontal movement, converting the horizontal movement into a vertical upward lifting movement, thereby raising the installation height of the pad 8. Conversely, when the driving component 5 drives the first support base 3 and the second support base 4 to move further apart from each other, the installation height of the pad 8 decreases. In this way, the purpose of rapid leveling is achieved, the pad 8 in the middle can be raised smoothly, ensuring the levelness of the equipment, and the structure is simple and reliable, with strong environmental adaptability, facilitating on-site installation, commissioning and daily maintenance.

[0032] In one specific embodiment, the sliding component 2 includes a guide rail 21 and two sliders. The guide rail 21 is mounted on the base 1, one slider is mounted on the first support 3 and slidably connected to the guide rail 21, and the other slider is mounted on the second support 4 and slidably connected to the guide rail 21. It should be noted that there are two sliding components 2, which are spaced apart on the base 1 to ensure that the first support 3 and the second support 4 are evenly stressed on both sides, preventing offset or tilting.

[0033] In one specific embodiment, the first support base 3 includes a first support frame 31, a first wedge block 32, and a first connecting block 33. The first support frame 31 is inverted U-shaped, and first mounting grooves 34 are provided at both ends of the first support frame 31. The slider is installed in the first mounting groove 34. The first support frame 31 is slidably connected to the guide rail 21 through the slider. The first ramp 30 is provided on the first wedge block 32. The first wedge block 32 is installed on the top of the middle section of the first support frame 31. The first connecting block 33 is installed on the bottom of the middle section of the first support frame 31 and connected to the driving component 5.

[0034] In one specific embodiment, the second support base 4 includes a second support frame 41, a second wedge block 42, and a second connecting block 43. The second support frame 41 is inverted U-shaped, and second mounting grooves 44 are provided at both ends of the second support frame 41. The slider is installed in the second mounting grooves 44. The second support frame 41 is slidably connected to the guide rail 21 through the slider. The second ramp 40 is provided on the second wedge block 42. The second wedge block 42 is installed on the top of the middle section of the second support frame 41. The second connecting block 43 is installed on the bottom of the middle section of the second support frame 41 and connected to the driving component 5.

[0035] Thus, the first support frame 31 and the second support frame 41 can move linearly along the guide rail 21. When the driving component 5 is activated, it can drive the first support seat 3 and the second support seat 4 to move toward or away from each other.

[0036] In one specific embodiment, the drive component 5 includes a bidirectional ball screw 51, a first nut seat 52, and a second nut seat 53. The bidirectional ball screw 51 is rotatably mounted on the base 1 via a mounting seat 6 and includes a first screw portion 511 and a second screw portion 512 coaxially connected to the first screw portion 511. The thread direction of the first screw portion 511 is opposite to that of the second screw portion 512. The first nut seat 52 is threadedly connected to the first screw portion 511 and fixed to the first connecting block 33. The second nut seat 53 is threadedly connected to the second screw portion 512 and fixed to the second connecting block 43.

[0037] Thus, when the bidirectional ball screw 51 rotates, it can synchronously drive the first support seat 3 and the second support seat 4 to move closer to or further away from each other, ensuring that the stroke and speed of the first support seat 3 and the second support seat 4 are completely consistent. By changing the direction of rotation of the bidirectional ball screw 51, the first support seat 3 and the second support seat 4 can be driven to move closer to or further away from each other, eliminating the need for dual drive and transmission methods, simplifying the overall transmission structure, reducing power and transmission components, and lowering equipment manufacturing costs and assembly difficulty.

[0038] In one specific embodiment, the drive component 5 further includes a gear 54 and a locking assembly 55. The gear 54 is connected to one end of the bidirectional ball screw 51, and the locking assembly 55 is mounted on the mounting base 6 and distributed close to the gear 54. The locking assembly 55 is used to restrict the rotation of the gear 54.

[0039] When it is necessary to drive the first support seat 3 and the second support seat 4 to move, the locking component 55 does not limit the toothed disc 54, and the bidirectional ball screw 51 can rotate normally; when the position of the pad 8 on the first support seat 3 and the second support seat 4 is adjusted, the locking component 55 limits the toothed disc 54 to prevent the toothed disc 54 and the bidirectional ball screw 51 from rotating, so as to keep the position of the first support seat 3 and the second support seat 4 unchanged.

[0040] In one specific embodiment, the locking assembly 55 includes a U-shaped mounting rod 551, an elastic element 552, a mounting plate 553, and a pin 554. The U-shaped mounting rod 551 is slidably mounted on the mounting base 6. The elastic element 552 is installed in the slot 61 of the mounting base 6, with one end connected to the mounting base 6 and the other end connected to the mounting plate 553. The mounting plate 553 is connected to both ends of the U-shaped mounting rod 551 and distributed near the gear disc 54. A locking block 555 protrudes from the side of the mounting plate 553 near the gear disc 54. The pin 554 is detachably mounted on the mounting base 6 and located between the gear disc 54 and the locking block 555. It should be noted that in this embodiment, the elastic element 552 is a spring.

[0041] When the installation height of the pad 8 on the first support 3 and the second support 4 is adjusted, the pin 554 is removed from the mounting base 6. The elastic element 552 extends and drives the locking block on the mounting plate 553 to engage with the gear plate 54 to limit the gear plate 54. At this time, the gear plate 54 and the bidirectional ball screw 51 are locked and cannot rotate. Even when the pad 8 is under pressure, the positions of the first support 3 and the second support 4 remain unchanged. After adjustment, mechanical self-locking can be achieved, and the position of the pad can remain unchanged and is not easy to shift.

[0042] When it is necessary to adjust the installation height of the pad 8 on the first support 3 and the second support 4, insert the pin 554 back to its original position and block it between the gear plate 54 and the locking block to compress the elastic element 552 and prevent the locking block from meshing with the gear plate 54. At this time, the gear plate 54 and the bidirectional ball screw 51 can rotate normally to adjust the installation height of the pad 8 on the first support 3 and the second support 4.

[0043] In one specific embodiment, the gear disk 54 is provided with a starter cylinder 541, which is connected to a matching crank handle. The gear disk 54 can be driven to rotate by hand-cranking the crank handle. Manual start-up can be achieved without electricity, making it suitable for scenarios without power supply and highly practical. The overall mechanical structure is simple and durable with a low failure rate. It is easy to operate and control, effectively ensuring smooth start-up of the equipment and improving its stability and applicability.

[0044] In one specific embodiment, the stepped pad mechanism with quick leveling function further includes an anti-detachment guide mechanism 7. The anti-detachment guide mechanism 7 includes a receiving cylinder 71, an anti-detachment plate 72, and a locking buckle 73. A guide post 81 is formed by a protrusion at the bottom of the pad 8. The guide post 81 is movably inserted into the receiving cylinder 71. The receiving cylinder 71 is installed on the base 1. The anti-detachment plate 72 has an anti-detachment opening 721. The anti-detachment plate 72 is installed on the base 1, and the anti-detachment opening 721 faces upward. The locking buckle 73 is installed on the side of the pad 8 and slidably sleeved on the anti-detachment opening 721.

[0045] When the pad 8 is lifted, the guide post 81 is pulled out of the receiving cylinder 71 a certain distance. When the pad 8 is raised to the maximum limit height (that is, when the latch 73 reaches the top of the anti-disengagement opening 721), the latch 73 and the anti-disengagement opening 721 cooperate to restrict the pad 8 from continuing to lift. It can also prevent the pad 8 from being released from the first support frame 31 and the second support frame 41, thereby enhancing the stability of the pad 8 during movement.

[0046] In this way, the lifting stroke of the pad 8 can be precisely limited to avoid overtravel, and the pad 8 can be firmly locked to prevent it from slipping and loosening. This effectively restricts the movement gap of the pad 8, greatly improves the running stability of the pad 8 and the overall assembly firmness, and ensures the safe and stable operation of the equipment.

[0047] The present invention is not limited to the description in the specification and embodiments, and thus other advantages and modifications can be readily realized by those skilled in the art. Therefore, the present invention is not limited to the specific details, representative devices and illustrated examples shown and described herein without departing from the spirit and scope of the general concept as defined by the claims and their equivalents.
