Description

Technical Field

[0001] This utility model relates to the field of linear module technology, specifically a high-stability base structure for linear modules. Background Technology

[0002] As a core moving component of modern automated equipment, the performance of linear modules directly affects the machining accuracy and stability of the entire machine.

[0003] Traditional base structures often use cast iron or welded steel frames as support bodies, with each functional component rigidly connected by bolts. Although this design is simple and has a strong load-bearing capacity, it has obvious vibration transmission problems. When the motor starts or stops or the load changes suddenly, the mechanical vibration generated by the moving parts will be directly transmitted to the base through the rigid connection. The vibration causes the guide rail slider to wobble slightly, affecting the positioning repeatability. At the same time, continuous vibration accelerates the fatigue failure of the ball screw and bearings, affecting the work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable base structure for linear modules, so as to solve the problem of low working efficiency caused by the lack of shock-absorbing components in the traditional base structure for linear modules mentioned in the background art.

The base serves as the supporting foundation for the entire device, undertaking the function of fixing and bearing other components. The motor connecting piece is used to fix the motor and transmit the motor's driving force. The bearing seat supports the rotating shaft and ensures its stable rotation. The first through hole provides space for the rotating shaft to pass through and maintains axial positioning. The linear guide rail provides a precise linear motion track for the slider. The level is used to detect the horizontal state of the base to ensure operating accuracy. The baffle prevents the slider from deviating from the track during movement.

[0008] Preferably, the shock absorption assembly includes a connecting seat, which is movably disposed on the lower side of the base. Fixing plates are fixedly disposed at the front and rear ends of the connecting seat. The connecting seat, as the core component of the shock absorption assembly, connects the base and the operating table. The fixing plates securely fix the entire device to the operating table with fastening bolts.

[0009] Preferably, the fixing plate is mounted on the operating table by fastening bolts, and the connecting seat has several second through holes, which provide installation positions for the adjusting bolts.

[0010] Preferably, the lower end of the connecting seat has a slot, and a guide rod is fixedly provided between the connecting seat and the base. The slot, together with the adjusting bolt, realizes the adjustment of the shock absorption force, and the guide rod restricts the relative displacement direction between the base and the connecting seat.

[0011] Preferably, an adjusting bolt is fixedly installed inside the slot. The adjusting bolt passes through the second through hole and connects to the screw hole at the bottom of the base. The adjusting bolt is used to adjust the preload of the shock absorption assembly to adapt to different working conditions.

[0012] Preferably, a damper is fixedly disposed between the connecting seat and the base, and a spring is fixedly disposed on the outer ring of the damper. The damper absorbs the vibration energy generated during operation, and the spring and the damper cooperate to provide elastic buffering.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This linear module uses a highly stable base structure, and the innovatively designed shock absorption components significantly improve the operational stability. The base and the connecting seat adopt a dual buffer mechanism of damper and spring, which can effectively absorb the axial and radial vibrations generated when the motor drives the lead screw to rotate. The adjusting bolt can adjust the damper preload in real time to adapt to different load conditions. The guide rod precisely limits the displacement of the connecting seat, ensuring that the vibration energy is dissipated in a directional manner, making it suitable for high-precision machining scenarios.

[0015] 2. This linear module uses a highly stable base structure. The motor connecting piece and bearing seat are quickly aligned and installed through through holes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a high-stability base structure for a linear module. The high-stability base structure includes a base 1, a profile 2 fixedly mounted on the upper end of the base 1, a motor connecting piece 3 fixedly mounted on the left end of the profile 2, and a bearing seat 4 fixedly mounted on the right side of the motor connecting piece 3. Both the motor connecting piece 3 and the bearing seat 4 have first through holes 5. A linear guide rail 6 is fixedly mounted on the upper end of the profile 2. A level 17 is fixedly mounted on the front end of the base 1, a baffle 7 is fixedly mounted on the right end of the profile 2, and a shock-absorbing component is mounted on the lower end of the base 1. The base 1 serves as an overall support platform, distributing loads and maintaining stability through a rigid structure. The motor connecting piece 3 provides an installation interface for the motor and transmits torque to the transmission system. The bearing seat 4 supports the rotating shaft and reduces frictional resistance. The first through holes 5 ensure precise alignment of the transmission shaft and maintain axial positioning. The linear guide rail 6 guides the slider through a precision raceway to achieve high-precision linear motion. The level 17 monitors the horizontal state of the equipment to ensure operational accuracy. The baffle 7 limits the slider's stroke range to prevent derailment.

[0024] The shock absorption assembly includes a connecting seat 8. The connecting seat 8 is movably disposed on the lower side of the base 1. The front and rear ends of the connecting seat 8 are fixedly disposed with fixing plates 9. The fixing plates 9 are mounted on the operating table by fastening bolts 10. The connecting seat 8 has several second through holes 11. The connecting seat 8 serves as the carrier of the shock absorption system to realize the flexible connection between the base and the operating table. The fixing plates 9 are fixed to the operating surface by bolts. The fastening bolts 10 provide a detachable rigid connection method. The second through holes 11 provide multiple installation position options for the adjustment mechanism.

[0025] The lower end of the connecting seat 8 has a slot 12. A guide rod 13 is fixedly installed between the connecting seat 8 and the base 1. An adjusting bolt 16 is fixedly installed inside the slot 12. The adjusting bolt 16 passes through the second through hole 11 and connects to the screw hole at the bottom of the base 1. A damper 14 is fixedly installed between the connecting seat 8 and the base 1. A spring 15 is fixedly installed on the outer ring of the damper 14. The slot 12 accommodates the adjusting bolt and allows for fine-tuning of its position. The guide rod 13 limits the movement trajectory of the damping component to avoid uneven loading. The adjusting bolt 16 adjusts the preload of the damping system through the threaded pair. The damper 14 consumes vibration energy using the principle of fluid resistance. The spring 15 stores and releases kinetic energy through elastic deformation to achieve buffering.

[0026] Working principle: The motor is installed on the left side of the motor connecting piece 3. The motor rotating shaft passes through the first through hole 5, is connected by a coupling, and passes through the bearing seat 4 to the right side of the connecting screw. The connecting screw is fitted with a connecting block and a ball nut and is connected to the slider. The linear guide rail 6 provides a sliding track for the slider. When the motor drives the screw to rotate, it drives the slider to move along the linear guide rail 6. The vibration generated during operation is transmitted to the base 1 and buffered by the shock absorption component. When the vibration is transmitted to the connecting seat 8, it is absorbed by the damper 14 and the spring 15. The preload of the damper 14 and the spring 15 can be changed by adjusting the adjusting bolt 16 to adapt to different working conditions. The guide rod 13 limits the relative displacement between the connecting seat 8 and the base 1. The level 17 is used to monitor the level of the base 1. The baffle 7 prevents the slider from falling off the linear guide rail 6. The fixing plate 9 fixes the entire device to the operating table by fastening bolts 10. The connecting seat 8 is installed with the adjusting bolt 16 through the slot 12 and the second through hole 11.
