A sliding unloading mechanism is arranged inside the storage plate 2, and a positioning and disassembly assembly is arranged inside the storage plate 2.

[0026] Embodiment 1: The sliding unloading mechanism includes a storage plate 2 slidably connected to the outside of the guide rail body 1. The cross-sectional shape of the guide rail body 1 is T-shaped. A plurality of balls 15 are rollingly connected to the inner side of the storage plate 2, and the balls 15 fit the outer side of the guide rail body 1. The arrangement of the balls 15 is convenient for utilizing, while maintaining the smooth movement of the storage plate 2, reducing the influence of friction on the storage plate 2. Two buffer chambers 201 are opened inside the storage plate 2.

[0027] Among them, an upper push plate 8 is movably connected in the buffer cavity 201 of the storage plate 2, and a connecting rod 9 that is slidably adapted to the storage plate 2 is fixedly connected to the bottom of the upper push plate 8, and a lower push plate 10 is fixedly connected to the bottom of the connecting rod 9, so that the lower push plate 10 can move with the upper push plate 8 under the action of the connecting rod 9.

[0028] In this embodiment, the bottom of the lower push plate 10 is fixedly connected to a mounting frame 11, and the interior of the mounting frame 11 is rotatably connected to a plurality of rollers 12, so that the rollers 12 can be used to reduce the influence of friction on the movement of the storage plate 2. A buffer assembly for pushing the upper push plate 8 is provided in the buffer cavity 201 of the storage plate 2.

[0029] Among them, the buffer assembly includes a fixed plate 3 fixedly connected to the inside of the storage plate 2, and the fixed plate 3 is located in the buffer cavity 201. There are two fixed plates 3, and the opposite side and the separated side of the two fixed plates 3 are fixedly connected with fixed rods 4. The outer side of the fixed rod 4 is sleeved with two sliding sleeves 5. The outer side of the fixed rod 4 is sleeved with a buffer spring 6 located between the sliding sleeve 5 and the fixed plate 3, and the two ends of the buffer spring 6 are respectively connected to the sliding sleeve 5 and the fixed plate 3.

[0030] Among them, the bottom of the sliding sleeve 5 is rotatably connected to a push rod 7 hinged to the upper push plate 8, so that the sliding sleeve 5 can use the push rod 7 to apply pressure to the upper push plate 8 under the push of the buffer spring 6, so as to achieve load buffering and force unloading. The left and right sides of the sliding sleeve 5 are fixedly connected with sliding blocks that are slidably adapted to the storage plate 2, so that the sliding blocks can be used to maintain the stability of the sliding sleeve 5. The bottom of the storage plate 2 is provided with a telescopic hole corresponding to the position of the connecting rod 9, so that the connecting rod 9 can pass through the storage plate 2 using the telescopic hole.

[0031] In this embodiment, a guide assembly for guiding the sliding of the roller 12 is provided inside the guide rail body 1, and the guide assembly includes a limit frame 13 fixedly connected inside the guide rail body 1, so that the structural characteristics of the limit frame 13 can be used to guide the roller 12 to move inside the guide rail body 1, thereby improving the activity stability of the storage plate 2. A buffer pad 14 is fixedly connected to the top of the limit frame 13, so that the buffer pad 14 can be used to prevent the limit frame 13 and the storage plate 2 from being damaged due to hard collision.

[0032] Among them, two sliding grooves 101 are opened on the top of the guide rail body 1, and the limit frame 13 is located in the sliding groove 101, which is convenient for fixing the limit frame 13 in the guide rail body 1 by utilizing the setting of the sliding groove 101. The cross-sectional shape of the limit frame 13 is U-shaped, which is convenient for utilizing the structural characteristics of the limit frame 13 to limit the left and right movements of the push-down plate 10 and the roller 12 in the limit frame 13.

[0033] It should be noted that the sliding guide unloading device of the machine tool machining center, through the provided sliding unloading mechanism, when the storage plate 2 is mounted on the outside of the guide rail body 1 for use, can not only use the provided buffer assembly to push the plate 8 upward to apply pressure, so that the roller 12 in the mounting frame 11 presses against the guide rail body 1 to achieve buffering and unloading of the load, but also can use the setting of the roller 12 and the ball 15 to reduce the friction effect on the sliding of the storage plate 2 outside the guide rail body 1, thereby ensuring the smooth sliding of the storage plate 2 while extending the service life of the storage plate 2 and the guide rail body 1, and effectively improving the practical effect of the device.

[0034] Embodiment 2: The positioning and disassembly assembly includes a pull rod 16 slidably connected to the inside of the storage plate 2, and one end of the pull rod 16 close to the guide rail body 1 is fixedly connected to the limit block 17. The left side of the guide rail body 1 is provided with a limit groove 102 slidably adapted to the limit block 17, and the number of the limit grooves 102 is multiple. The outer side of the pull rod 16 is sleeved with an extrusion spring 18 fixedly connected to the limit block 17 and the storage plate 2, so that the limit block 17 can be extended into the limit groove 102 under the action of the extrusion spring 18, thereby fixing the storage plate 2.

[0035] It should be noted that the sliding guide unloading device of the machine tool machining center, through the positioning and disassembly components, the limit block 17 arranged on the pull rod 16 can move towards the guide rail body 1 under the action of the extrusion spring 18, and when the limit block 17 extends to the limit groove 102 of the guide rail body 1, it can limit the sliding of the storage plate 2 on the guide rail body 1, thereby maintaining the stability of the installation, and in this process, only the pull rod 16 needs to be pulled to make the limit block 17 detach from the guide rail body 1 and resume its activity. This structure can not only facilitate the fixation of the storage plate 2, but also maintain its fixing effect.

[0036] The working principle of the above embodiment is:

[0037] When the sliding guide rail unloading device of the machine tool machining center is used, the object placement plate 2 needs to be mounted on the outer side of the guide rail body 1 first, and then the position of the object placement plate 2 on the guide rail body 1 can be adjusted as needed. When the object placement plate 2 is loaded, the movable sliding sleeve 5 on the fixed rod 4 can utilize the elasticity of the buffer spring 6 and cooperate with the upper push plate 8 to achieve load buffering and force unloading. In this process, the roller 12 installed at the bottom of the lower push plate 10 can cooperate with the ball 15 to reduce friction and keep the movement of the object placement plate 2 on the guide rail body 1 stable.

[0038] After the storage plate 2 is moved to a suitable position, the limit block 17 provided on the pull rod 16 can move toward the guide rail body 1 under the action of the extrusion spring 18. When the limit block 17 extends to the limit groove 102 of the guide rail body 1, the sliding of the storage plate 2 on the guide rail body 1 can be limited, thereby achieving the fixation of the storage plate 2. When it is necessary to restore the activity of the storage plate 2, the pull rod 16 can be pulled to restore the activity of the storage plate 2.
