[0002] The structure of the damper generally includes a damping plate and a piston rod. The damping plate is mounted on the piston rod (refer to Chinese patent document number CN101545344A, publication date: September 30, 2009). When the damping plate is installed, due to the position requirements of the damping plate and the piston rod, it is necessary to align the positioning hole on the damping plate with the positioning column of the piston rod (such as Figure 14 As shown in the figure, when installing the damping plate, it is necessary to rotate and automatically align the position and press down to install it accurately. Therefore, the damping plate can only be installed manually, and mechanical equipment cannot be used for installation. However, manual installation is inefficient and takes a long time to install. In addition, mass production cannot be achieved, and the labor cost required is relatively high.

[0003] Therefore, further improvements are necessary. Summary of the Invention

The linear sliding assembly includes at least a linear sliding part 6, wherein the bracket 5 includes a mounting vertical plate 19, a mounting base plate 15 and a slide rail mounting plate 16. The mounting base plate 15 is fixed on the workbench 1, the mounting vertical plate 19 is vertically mounted on the mounting base plate 15, the slide rail mounting plate 16 is mounted on the mounting vertical plate 19 and is vertically arranged, the driver 2 is fixedly installed with the mounting vertical plate 19 through a fixed plate 17, and the driver 2 is connected to the linear sliding part 6, the linear sliding part 6 is slidably arranged on the slide rail mounting plate 16, a pair of connecting plates 7 are extended from the linear sliding part 6, the connecting plates 7 are arranged up and down, the upper and lower ends of the rotating part 3 are respectively rotatably connected to the corresponding connecting plates 7, and the fixed part 4 is fixed on the fixed plate 17; the driver 2 drives the linear sliding part 6 to move linearly up and down, and the linear sliding part 6 drives the rotating part 3 to move linearly up and down synchronously. When the rotating part 3 moves linearly up and down, the fixed part 4 acts on the rotating part 3 to make the rotating part 3 rotate while moving linearly up and down.

[0034] The assembly mechanism also includes a transmission component and at least one workpiece assembly device 8. The rotating part 3 is connected to the workpiece assembly device 8 through the transmission component. The rotating part 3 drives the workpiece assembly device 8 to perform linear and rotational motions at the same time through the transmission component. The workpiece assembly device 8 is a floating press sleeve.

[0035] The fixing member 4 is provided with a joint member 9, and the rotating member 3 is provided with a joint portion 3.1, and the joint member 9 is engaged with the joint portion 3.1.

[0036] Rotating member 3 is a worm, screw, or gear; engaging member 9 is a latch that engages with the worm or screw, or a rack that engages with the gear. In this embodiment, rotating member 3 is a worm, fixing member 4 is a latch fixing plate, and engaging member 9 is a latch. The latch is mounted at the bottom of the latch fixing plate, and engaging portion 3.1 is a spiral groove. When the worm moves linearly up and down, the latch acts on the spiral groove, causing the worm to rotate simultaneously through the engagement of the spiral groove and the latch.

[0037] The assembly mechanism also includes a linear part 10, which is a slide rail. A linear groove 5.1 is provided on the slide rail mounting plate 16. The slide rail limit is set in the linear groove 5.1 (that is, the slide rail is inserted into the linear groove 5.1). The linear sliding part 6 is a slider mounting plate.

The first transmission component 11 of this embodiment is a large gear, and the second transmission component 12 is a small gear. The large gear and the small gears are meshed with each other. There is one large gear and two small gears. The small gears are connected to a gear shaft 20. A gear shaft mounting plate 21 is extended on the linear slide 6. The gear shaft 20 is rotatably mounted on the gear shaft mounting plate 21. The workpiece assembly device 8 is a floating press sleeve. The floating press sleeve is mounted on the lower end of the gear shaft 20, and the floating press sleeve corresponds to the gear shaft 20 one by one. When the rotating member 3 moves, it drives the large gear to perform up and down linear motion and rotational motion.

The linear slide 6 drives the gear shaft and the small gear to perform up and down linear motion through the gear shaft mounting plate 21, so that the gear shaft and the small gear can also perform up and down linear motion and rotational motion at the same time. Then the gear shaft drives the floating press sleeve to perform up and down linear motion and rotational motion to realize the assembly of the workpiece; in addition, by cooperating with one large gear and two small gears, the assembly mechanism (driver) can complete the installation of two groups of workpieces in one stroke, realizing mass production and greatly improving the installation efficiency.

[0039] The workpiece assembly device 8 is provided with a workpiece fixed portion 8.1 for assembling the workpieces. The workpieces include a first workpiece 13 and a second workpiece 14. The first workpiece 13 is a damping plate, and the second workpiece is a piston rod. A turntable 22 is provided on the workbench 1. The piston rod is arranged at the assembly station of the turntable 22, and the assembly mechanism is located next to the turntable 22. When the workpiece assembly equipment is in operation, the turntable 22 rotates on the workbench 1. When the assembly station of the turntable 22 rotates to the position of the assembly mechanism, the turntable 22 pauses. The assembly mechanism then installs the damping plate on the piston rod. After installation is completed, the turntable 22 resumes rotation and pauses when it rotates to the assembly mechanism position at the next assembly station. The next damping plate is installed, and the cycle continues. The damping plate is provided with a positioning hole 13.1, and the piston rod is provided with a positioning post 14.1. During installation, the damping plate is placed on the workpiece fixed portion 8.1. The workpiece assembly device 8 drives the damping plate in vertical linear and rotational motion, so that the positioning hole 13.1 can be aligned with the positioning post 14.1. In this way, the positioning hole 13.1 can be smoothly inserted into the positioning post 14.1, allowing the damping plate to be accurately installed in the piston rod. In addition, the workpiece assembly equipment is equipped with an electronic control device (such as a computer, PLC, etc.), which controls the operation of the turntable 22 and the driver 2.

[0040] The actuator 2 is a pneumatic cylinder or motor, which is connected to the linear slide 6 via a telescopic rod 2.1. In this embodiment, the actuator 2 is a pneumatic cylinder, and the telescopic rod 2.1 is a pneumatically retractable piston rod. The top of the linear slide 6 is provided with a cylinder joint 6.1, and the telescopic rod 2.1 is connected to the cylinder joint 6.1.

[0041] Working principle of assembly mechanism:

[0042] The cylinder pushes the linear slide 6 to move linearly downward, and the linear slide 6 drives the worm to move linearly downward synchronously. While the worm is moving linearly downward, the pin acts on the spiral groove of the worm, causing the worm to rotate at the same time. Then the worm drives the large gear to move linearly and rotationally downward, and the large gear drives the small gears and the gear shaft 20 to rotate. The linear slide 6 drives the small gears and the gear shaft 20 to move linearly downward, and then drives the floating pressure sleeve to move linearly and rotationally downward through the gear shaft 20. The floating pressure sleeve drives the damping plate to rotate and correct the position and press the damping plate down into the piston rod. After the damping plate is installed, the cylinder drives the linear slide 6 to move linearly upward to prepare for the next installation of the damping plate.

[0043] Second embodiment

[0044] The present workpiece assembly device is different from the first embodiment in that:

[0045] The assembly mechanism also includes a workpiece assembly device 8, which is connected to the rotating part 3. When the rotating part 3 moves, it drives the workpiece assembly device 8 to perform linear motion and rotational motion at the same time. In this embodiment, only one workpiece assembly device 8 is provided, which is directly driven by the rotating part 3 to move, eliminating the transmission component, but the production efficiency is lower than that of the first embodiment.

[0046] Other undescribed parts are the same as those in the first embodiment and will not be analyzed or described here.
