Detailed Implementation

[0034] This utility model discloses a longitudinal movement drive fixture and a ballastless track fastener replacement device to solve the problem that existing drive mechanisms cannot move and position synchronously.

[0035] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0036] Please see Figure 1 , Figure 1 This is a structural schematic diagram of a longitudinal translation drive fixture 200 provided in an embodiment of this application.

[0037] In one specific embodiment, the longitudinal movement drive fixture 200 in this application includes:

[0038] The longitudinal guide device is arranged along the longitudinal direction of the longitudinal drive support 201, and includes a longitudinal sliding body 202 and a longitudinal sliding rod 203. The longitudinal sliding rod 203 is located on the longitudinal drive support 201, and the longitudinal sliding body 202 is fitted on the longitudinal sliding rod 203 and moves along the longitudinal sliding rod 203.

[0039] The longitudinal positioning drive device has one of its fixed end and telescopic end connected to the longitudinal sliding body 202 and the other connected to the longitudinal drive support 201, driving the longitudinal sliding body 202 to slide along the longitudinal sliding rod 203.

[0040] The longitudinal drive device 205 is fixed on the longitudinal sliding body 202; the longitudinal drive device 205 has a telescopic end for connecting with the component, and the telescopic end of the longitudinal drive device 205 can reciprocate longitudinally.

[0041] The longitudinal drive support 201 is a plate structure, such as a rectangular plate, which can be made of Q345B steel plate, with mounting holes at the bottom. The longitudinal guide device includes a longitudinal sliding body 202, a longitudinal sliding rod 203, and two longitudinal sliding rod seats 204. The two longitudinal sliding rod seats 204 are arranged opposite each other in the longitudinal direction of the longitudinal drive support 201 and are symmetrically fixed to both ends of the longitudinal drive support 201 by bolts. The two ends of the longitudinal sliding rod 203 are inserted into the positioning grooves of the longitudinal sliding rod seats 204, and the two ends of the longitudinal sliding rod 203 are fixedly connected to the corresponding longitudinal sliding rod seats 204 by a heat-fitting process. The longitudinal sliding body 202 is fitted onto the longitudinal sliding rod 203 and moves linearly along the longitudinal sliding rod 203. The longitudinal guide device provides stable guidance for the longitudinal drive device 205, ensuring the linearity and stability during the sliding process, preventing deflection or shaking, and improving positioning accuracy.

[0042] The fixed end of the longitudinal positioning drive device is connected to the longitudinal sliding body 202, and the other end is connected to the longitudinal drive support 201. It can be set as an actuator such as a cylinder, hydraulic cylinder or electric push rod to push the longitudinal sliding body 202 to move along the longitudinal sliding rod 203 to achieve precise positioning of the longitudinal sliding body 202. Through the telescopic movement of the longitudinal positioning drive device, the longitudinal sliding body 202 is pushed to slide along the longitudinal sliding rod 203 to reach the target area to achieve coarse positioning.

[0043] The longitudinal drive device 205 is fixed on the longitudinal sliding body 202. The telescopic end of the longitudinal drive device 205 is connected to the component. It can be configured as a cylinder or a hydraulic cylinder and has at least two stop positions.

[0044] The longitudinal drive fixture 200 and ballastless track fastener replacement device provided in this application embodiment have the following technical advantages compared with the prior art:

[0045] The longitudinal positioning drive device and the longitudinal drive device 205 are set separately to achieve coarse positioning and fine adjustment, so as to solve the problem that the traditional single drive system cannot take into account both large stroke and high precision. The longitudinal guide device provides stable guidance for the sliding body, ensuring the straightness and smoothness during the sliding process, preventing deflection or shaking, and improving positioning accuracy. After the longitudinal positioning drive device completes the positioning, the longitudinal drive device 205 applies a drive to the target component to achieve fine adjustment of the component.

[0046] In this embodiment, the longitudinal guide device further includes two opposing longitudinal slide rod seats 204, which are fixed to the longitudinal drive support 201; the longitudinal ends of the longitudinal slide rod 203 are respectively fixedly connected to the longitudinal slide rod seats 204.

[0047] In another embodiment, the longitudinal positioning drive device includes:

[0048] Longitudinal positioning drive component 206;

[0049] The longitudinal positioning drive component support 207 is fixed on the longitudinal sliding body 202, and the longitudinal positioning drive component 206 is disposed on the longitudinal positioning drive component support 207.

[0050] The longitudinal positioning drive rod seat 208 is fixed on the longitudinal sliding rod seat 204, and the telescopic end of the longitudinal positioning drive 206 is connected to the longitudinal positioning drive rod seat 208.

[0051] The longitudinal positioning drive component 206 can be configured as a pneumatic cylinder, hydraulic cylinder, or servo electric cylinder, etc., responsible for outputting linear motion to push the sliding body to move longitudinally and achieve positioning. The longitudinal positioning drive component support 207 is the mounting base for fixing the drive component; the installation position is the longitudinal sliding body 202, that is, it moves together with the longitudinal sliding body 202; the longitudinal positioning drive component 206 is fixed to the support by bolts, welding, etc.; so that the longitudinal positioning drive component 206 moves synchronously with the longitudinal sliding body 202, which facilitates cooperation with the fixed end.

[0052] The longitudinal positioning drive rod seat 208 is the connection point of the telescopic end of the longitudinal positioning drive 206. When the longitudinal positioning drive 206 moves, its telescopic end drives the longitudinal positioning drive rod seat 208 to move, realizing the movement of the sliding body relative to the support, thereby improving transmission efficiency and stability.

[0053] When the longitudinal positioning drive 206 is activated, its telescopic end pushes or pulls the rod seat, thereby causing the longitudinal sliding body 202 to slide along the longitudinal sliding rod 203, achieving precise control of the sliding body's position. This structure has a reasonable layout, uniform force distribution, and good guidance and stability, making it particularly suitable for automated equipment applications requiring frequent positioning and high-precision operation.

[0054] In one embodiment, the longitudinal positioning drive 206 is a servo electric cylinder or a proportional control cylinder with a displacement controller; the longitudinal drive device 205 is a pneumatic cylinder or a hydraulic cylinder.

[0055] In one embodiment, the longitudinal guide device is a linear guide rail.

[0056] Specifically, the longitudinal guide device is a ball spline structure, and the spline groove depth is 15%-20% of the diameter of the slide rod.

[0057] In a preferred embodiment of this utility model, the longitudinal guide device adopts a ball spline structure, including a slide rod with a spline groove and a sliding body fitted thereon. The sliding body is provided with a ball assembly, and the balls roll along the spline groove to achieve smooth movement of the sliding body relative to the slide rod. The depth of the spline groove is 15%-20% of the diameter of the slide rod. This proportion design ensures effective contact of the balls while taking into account the structural strength and guiding stability of the slide rod. This structure not only improves the guiding accuracy and load-bearing capacity, but also has a certain anti-torsional performance, making it particularly suitable for automated production lines and industrial robot applications with high requirements for positioning accuracy and motion stability.

[0058] In one alternative embodiment, it further includes:

[0059] A displacement sensor is used to monitor the position of the longitudinal sliding body 202;

[0060] The PLC controller dynamically adjusts the longitudinal positioning drive based on displacement feedback.

[0061] In a preferred embodiment of this invention, the longitudinal movement drive fixture 200 further includes a displacement sensor and a PLC controller. The displacement sensor is mounted on the longitudinal sliding body 202 or the slide bar to monitor the current position of the sliding body in real time and feed the displacement information back to the PLC controller. The PLC controller receives the displacement feedback signal and, in conjunction with a preset target position, dynamically adjusts the action of the longitudinal movement positioning drive device to achieve precise control of the sliding body position. This control system adopts a closed-loop feedback mechanism, which can effectively compensate for mechanical errors and improve positioning accuracy and response speed.

[0062] This also includes a mechanical safety locking mechanism, including:

[0063] The hydraulic pin is located inside the longitudinal sliding rod seat 204;

[0064] Locking holes are spaced apart along the length of the longitudinal sliding rod 203. In an emergency, the hydraulic pin is inserted into the locking hole to fix the position.

[0065] The longitudinal drive fixture 200 also includes a safety locking mechanism for physically locking the sliding body in an emergency. The safety locking mechanism includes a hydraulic pin and locking holes spaced apart along the length of the longitudinal slide bar 203. The hydraulic pin is located inside the longitudinal slide bar seat 204 and automatically extends when the control system is triggered or the hydraulic system is depressurized, inserting into the locking hole corresponding to the current position of the sliding body, thereby fixing the position of the sliding body. This locking mechanism is compact, responsive, and provides reliable mechanical protection in dangerous situations such as power failure, emergency stop, or abnormal displacement, effectively ensuring operational safety. It is particularly suitable for high-risk operating environments and highly automated industrial equipment applications.

[0066] This application also provides a ballastless track fastener replacement device, including the longitudinal movement drive fixture 200 described in any of the above embodiments.
