Description

Technical Field

[0001] This utility model relates to the field of displacement compensation technology, and in particular to an automated machining displacement compensation device. Background Technology

[0002] A displacement compensator is a device used to absorb axial, lateral, or angular displacements of pipelines or structures caused by factors such as temperature changes and mechanical vibrations, preventing stress damage caused by displacement. The displacement compensator compensates for axial, lateral, or angular displacements of pipelines or equipment caused by thermal expansion and contraction, vibration, or foundation settlement through the deformation of its components.

[0003] A search revealed that utility model patent CN209385561U discloses a vibration damping device, particularly a vibration damping displacement compensation device. The purpose of this utility model is to provide a vibration damping displacement compensation device with good vibration damping effect and long service life. It includes a base plate, a guide sleeve, an elastic component, a sliding component, a gasket, a vibration damping component, and fixing bolts. Multiple anchor bolts for connection to the foundation are provided on the base plate. The guide sleeve is hollow with an unclosed cylindrical structure at the upper end. This unique structural design effectively reduces the vibration and noise generated by centrifuges, air compressors, separators, or blowers during operation. Furthermore, since the bottom of the centrifuge, air compressor, separator, or blower is placed on the vibration damping component via the sliding component, the sliding component can achieve horizontal displacement compensation within the vibration damping component. This reduces damage to the equipment caused by internal stress impacts due to sudden changes in horizontal loads or changes in temperature of horizontal pipelines.

[0004] In the structure disclosed above, the damping component moves up and down in the length direction of the guide sleeve under the action of the elastic component to achieve horizontal displacement compensation. However, this displacement compensation method is a passive compensation, and its compensation distance relies solely on the elastic deformation of the elastic component.

[0005] Components in existing automated processing equipment, such as equipment guide rails, inevitably undergo slight deformation and displacement after a period of use. At this time, relying solely on elastic components can only ensure buffering, but it is difficult to guarantee displacement compensation. This can lead to guide rail misalignment, resulting in material falling and damage or jamming, which reduces yield and production efficiency. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated machining displacement compensation device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automated processing displacement compensation device, comprising a support body, the support body including a crossbeam, a transport frame fixed to the top of the crossbeam, multiple load-bearing components fixed to the top of the transport frame, fixed components fixed at the corresponding positions of the crossbeam and the load-bearing components, a movable component slidably connected to the inner wall of the fixed component, a buffer module provided on the inner wall of the movable component, a threaded rod threadedly connected to the inner wall of the movable component, a bearing seat fixed to the inner wall of the fixed component, the circumferential surface of the threaded rod rotatably connected to the inner wall of the fixed component through the bearing seat, and an auxiliary through slot provided at the corresponding positions of the crossbeam and the threaded rod.

[0008] Preferably, the end of the moving member near the fixed member is shaped like a convex character, and the end of the fixed member near the moving member is shaped like a concave character, with the concave part of the fixed member fitting against the convex part of the moving member.

[0011] Preferably, extension members are fixed on both sides of the bottom end of the contact member, and limiting grooves are provided on both sides of one end of the moving member.

[0012] Preferably, one end of the contact member has multiple screw holes, and the surface of the carrier member has multiple screw holes.

[0013] Preferably, the inner wall of the limiting groove is provided with a reserved groove.

[0014] Preferably, a limiting block is fixed on both sides of the top of the contact member, and a limiting groove is provided on both sides of the inner wall of the rectangular groove of the moving member, and the inner wall of the limiting groove is slidably connected to the side of the limiting block.

[0015] Beneficial effects:

[0016] 1. This utility model enables workers to drive a threaded rod to rotate via an external motor, causing the threaded connection to gradually move the moving part away from the stationary part, thereby adjusting the distance between the moving and stationary parts. After the equipment has been used for a period of time, the transport frame will shift relative to the crossbeam. Workers can actively compensate for the displacement by adjusting the distance between the moving and stationary parts to compress the transport frame, ensuring that the transport frame remains parallel to the crossbeam, preventing guide rail deviation, and achieving the effect of improving yield and production efficiency.

[0017] 2. This utility model achieves the effect of using the interlocking of concave and convex shapes between the fixed and moving parts, so that when the distance between the two changes, the concave part of the fixed part provides support, preventing the moving part from tilting downward when moving outward, which would lead to abnormal wear. This improves the service life of the equipment and ensures the stability of the moving part's operation.

[0018] 3. This utility model prevents the extension from being compressed too much and causing excessive pressure on the damping spring, which would otherwise damage the damping spring beyond its limit compression distance. The extension also limits the retraction distance of the contact when it retracts, thus better ensuring the use of the damping spring and improving its service life. Attached Figure Description

[0033] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0036] Reference Figures 1-6 An automated processing displacement compensation device includes a support body 1, which includes a crossbeam 102. A transport frame 101 is fixed to the top of the crossbeam 102, and multiple load-bearing components 103 are fixed to the top of the transport frame 101. Fixed components 7 are fixed at the corresponding positions of the crossbeam 102 and the load-bearing components 103. A moving component 2 is slidably connected to the inner wall of the fixed component 7. A buffer module is provided on the inner wall of the moving component 2, and a threaded rod 701 is threadedly connected to the inner wall of the moving component 2. A bearing seat 702 is fixed to the inner wall of the fixed component 7, and the circumferential surface of the threaded rod 701 is rotatably connected to the inner wall of the fixed component 7 through the bearing seat 702. An auxiliary through slot 703 is provided at the position corresponding to the threaded rod 701. The threaded rod 701 is rotated by an external motor, and the threaded connection causes the moving part 2 to gradually move away from the fixed part 7, thereby adjusting the distance between the moving part 2 and the fixed part 7. After the equipment has been used for a period of time, the transport frame 101 will be displaced relative to the cross frame 102. The operator can actively compensate for the displacement by adjusting the distance between the moving part 2 and the fixed part 7 to squeeze the transport frame 101, so that the transport frame 101 always remains parallel to the cross frame 102, preventing the guide rail from deviating and causing material to fall and be damaged or jammed.

[0037] The end of the moving part 2 near the fixed part 7 is shaped like a convex character, and the end of the fixed part 7 near the moving part 2 is shaped like a concave character. The concave part of the fixed part 7 fits into the convex part of the moving part 2. Through the interlocking of the concave and convex characters between the fixed part 7 and the moving part 2, the concave part of the fixed part 7 provides support when the distance between them changes, preventing the moving part 2 from tilting downward when moving outward, which would lead to abnormal wear and ensure the stability of the moving part 2.

[0038] Both the end of the moving part 2 near the fixed part 7 and the end of the fixed part 7 near the moving part 2 are covered with a rubber layer. The rubber layer provides cushioning between the two to prevent damage caused by hard collision or squeezing.

[0039] The buffer module includes a contact element 202. A rectangular groove is formed on the inner wall of the moving element 2, and the contact element 202 is slidably connected to the inner wall of the rectangular groove. Multiple sinks are formed at one end of the inner wall of the rectangular groove. A damping spring 201 is fixed to the inner wall of the middle sink, and one end of the damping spring 201 is fixed to one end of the contact element 202. A damper 203 is fixed to the inner wall of the other sinks, and one end of the damper 203 is fixed to one end of the contact element 202. During equipment production, the damping spring 201 and the damper 203 absorb vibration and convert it into elastic potential energy. The damper 203 converts the elastic potential energy into internal energy, thereby effectively buffering the carrier frame 101 and the load-bearing element 103 and compensating for some minor displacements, thus improving the stability of the components.

[0040] Both sides of the bottom end of the contact 202 are fixed with extensions 4, and both sides of one end of the moving part 2 are provided with limiting grooves 401. The extensions 4 and the limiting grooves 401 prevent the extensions 4 from being compressed too much and causing the damping spring 201 to exceed its limit compression distance and be damaged. This ensures that when the contact 202 retracts, the extensions 4 limit the retraction distance of the contact 202, thereby better ensuring the use of the damping spring 201.

[0041] The contact 202 has multiple screw holes 3 at one end, and the bearing 103 has multiple screw holes 3 on its surface. By providing screw holes 3 at the corresponding positions of the contact 202 and the bearing 103, it is easy for workers to disassemble and maintain the parts, prevent other components from blocking the view, and improve work efficiency.

[0042] The inner wall of the limiting groove 401 is provided with a reserved groove 5. The reserved groove 5 prevents the bolt from being higher than the surface of the contact member 202 after it is installed through the corresponding screw hole 3 of the contact member 202 and the bearing member 103. This would prevent the bolt from scratching or wearing the limiting groove 401 after the extension 4 of the contact member 202 comes into contact with the limiting groove 401, thereby improving the service life of the moving part 2.

[0043] Both sides of the top of the contact 202 are fixed with limiting blocks 6. Both sides of the inner wall of the rectangular groove of the moving part 2 are provided with limiting grooves 601. The inner wall of the limiting groove 601 is slidably connected to the side of the limiting block 6. Through the cooperation of the limiting block 6 and the limiting groove 601, the contact 202 slides stably in the rectangular groove of the moving part 2, preventing it from shaking when sliding. At the same time, the length of the limiting groove 601 further limits the sliding distance of the contact 202, preventing the damping spring 201 from exceeding the limit extension distance due to the interference of sliding outward, or the damping spring 201 from being compressed beyond the limit compression distance due to the interference of moving inward, thereby improving the service life of the buffer module. Specific Implementation Example 2:

[0045] Reference Figures 1-6In June 2025, an automotive parts factory discovered that the cumulative offset of the guide rail at the third station of its stamping production line was 0.8mm, causing the defect rate of precision bearing housing stamped parts to rise to 5.3%. Maintenance personnel activated this device. The crossbeam 102 of the main support 1 is integrally milled from 45# steel (hardness HRC28-32). The transport frame 101 is equipped with SBR20 linear guide rails, and the bearing component 103 is connected to the guide rail base via 8.8 grade M12 bolts. The groove of the fixed component 7 is inlaid with a polyurethane rubber layer (thickness 3mm, Shore hardness 80±3), and the protrusion of the moving component 2 is covered with a rubber layer of the same specification.

[0046] During the straightening operation, an external 1.5kW servo motor (rated torque 7.2N·m) drives a trapezoidal threaded rod 701 with a module of 0.5 to rotate, pushing the moving part 2 to translate 12.7mm along the inner wall of the stationary part 7. The convex-concave interlocking structure controls the offset angle within ±0.03°. The contact part 202, through the screw hole 3, presses the bearing part 103 with an M10 hex bolt, forcing the guide rail base to reset. After displacement compensation, the test showed that the parallelism error of the guide rail decreased from 0.8mm to 0.05mm, and the defect rate of stamped parts dropped to 0.6%. After the production line resumes operation, when the 800-ton punch press generates a 30Hz vibration, the contact element 202 compresses the DIN2093 standard damping spring 201 (12mm wire diameter, 50mm free length) and activates the SWC-25 type damper 203. The extension 4 and the limiting groove 401 are fitted together to limit the spring compression to ≤35% (overload protection). The limiting block 6 slides along the 60mm long limiting groove 601 to absorb 72% of the amplitude.

[0047] Three months later, during preventative maintenance, the pre-reserved groove 5 effectively avoided the bolt head when installing the bearing component 103 bolt, and the auxiliary groove 703 allowed the motor coupling to be quickly separated, reducing the maintenance time per station from 8 hours to 2 hours.

[0048] The working principle of this utility model is as follows: When the long-term operation of the equipment causes the carrier frame 101 to shift relative to the cross frame 102, the external motor drives the threaded rod 701 to rotate. Through the thread engagement with the inner wall of the moving part 2, the moving part 2 is pushed to slide horizontally along the inner wall of the fixed part 7. The protrusion of the moving part 2 and the concave part of the fixed part 7 engage to prevent skewing. The rubber layer of the contact surface buffers the collision, thereby actively adjusting the distance between the moving part 2 and the fixed part 7, forcing the contact part 202 to squeeze the bearing part 103 to correct the position of the carrier frame 101. When the equipment is running, the vibration is transmitted to the contact part 202 through the bearing part 103, causing it to slide in the rectangular groove of the moving part 2 to compress the shock-absorbing spring 201 and drive the damper 203 to dissipate energy. The extension part 4 cooperates with the limiting groove 401 to limit the maximum compression distance and prevent the spring from overloaded. At the same time, the limiting block 6 moves along the limiting slide groove 601 to ensure the stability of the buffer trajectory.

[0049] During installation and maintenance, bolts are fixed by passing through the screw holes 3 of the contact member 202 and the bearing member 103. The reserved groove 5 accommodates the bolt head to avoid scratching the limiting groove 401, and the auxiliary through groove 703 provides a connection position for the external motor.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
