[0026] The technical scheme of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Referring to Figs. 1-2 A port polishing device for stainless steel thermos bottle shell processing, comprising a workbench 10 and a polishing conveyor belt 22 vertically arranged on the workbench 10; the workbench 10 is provided with a displacement guide assembly 30 located at the front side of the polishing conveyor belt 22, a shell tool 50 is arranged above the displacement guide assembly 30, and a displacement transmission assembly 40 is arranged inside the displacement guide assembly 30.

[0028] The above scheme focuses on the synergistic effect of the displacement guide assembly 30 and the displacement transmission assembly 40 to realize efficient and accurate polishing of the port of the stainless steel thermos bottle shell. The displacement guide assembly 30 provides stable guidance and support for the polishing process through its structural design, ensuring the accuracy of the polishing action. The displacement transmission assembly 40 realizes accurate control of the shell tool 50 through the interaction of the internal components, thereby ensuring the polishing quality and efficiency.

[0029] The displacement guide assembly 30 includes two side plates 32 vertically fixed on the workbench 10 and extending downward below it, an L-shaped plate 31 fixed between adjacent side plates 32, an H-shaped plate 37 slidingly arranged above adjacent side plates 32, and a horizontal shaft 38 provided on the side of the H-shaped plate 37 away from the polishing conveyor belt 22; the displacement transmission assembly 40 includes an electric / gas push rod A 44 fixed at the bottom of the L-shaped plate 31, the output end of the electric / gas push rod A 44 penetrating through the L-shaped plate 31 and fixedly arranged with a wedge block 43, the back of the wedge block 43 being fixed with a sliding plate 41 sliding up and down on the front of the L-shaped plate 31; the displacement transmission assembly 40 further includes a support arm 45 fixedly arranged on the side of one of the side plates 32, the distal end of the support arm 45 being fixed with a positioning shaft 46, the outer portion of the positioning shaft 46 being rotatably connected with an S-shaped swing arm 47, the upper end of the swing arm 47 being sleeved on the outer portion of the horizontal shaft 38 and rotatably connected therewith, and the lower end of the swing arm 47 sliding along the inclined surface of the wedge block 43; the swing arm 47 is provided with a spring 42 at one end thereof, the spring 42 being fixed to the inner front wall of the workbench 10.

[0030] In this technical solution, the further defined features of the displacement guide assembly 30 and the displacement transmission assembly 40 provide a guarantee for achieving high precision and high efficiency in polishing the ports of the stainless steel vacuum flask shell. The displacement guide assembly 30, through the combination of the side plates 32, the L-shaped plate 31 and the H-shaped plate 37, constructs a stable guide structure, ensuring accurate positioning during polishing. The displacement transmission assembly 40, through the cooperative action of the electric / gas push rod A 44, the wedge block 43, the sliding plate 41, the support arm 45, the positioning shaft 46, the swing arm 47 and the spring 42, realizes accurate control of the shell tooling 50, thereby ensuring polishing quality and efficiency.

[0031] When the electric / gas push rod A 44 in the displacement transmission assembly 40 is activated, its output end pushes the wedge block 43, causing the wedge block 43 to move along the inclined surface of the L-shaped plate 31. The movement of the wedge block 43 drives the sliding plate 41 connected thereto to slide up and down, and further causes the swing arm 47 to rotate around the horizontal shaft 38 through the rotation of the support arm 45 and the positioning shaft 46. The rotation of the swing arm 47 pushes the H-shaped plate 37 to move along the guide structure of the side plates 32 and the L-shaped plate 31, thereby driving the shell tooling 50 to move longitudinally and realize polishing of the ports of the stainless steel vacuum flask shell. The spring 42 provides the necessary buffer and reset force for the system, ensuring the stability and accuracy of the polishing process. Through this design, even in the case of low intensity power output, efficient and accurate polishing of the ports of the vacuum flask shell can be achieved, significantly improving the processing quality and efficiency.

[0032] In some embodiments, the front surface of the L-shaped plate 31 is provided with a vertical sliding rail 33, and a vertical sliding block 34 is slidably arranged on the vertical sliding rail 33, and the front surface of the vertical sliding block 34 is fixed to the back surface of the sliding plate 41. By arranging the vertical sliding rail 33 on the front surface of the L-shaped plate 31, and slidably arranging the vertical sliding block 34 on the vertical sliding rail 33, and fixing the front surface of the vertical sliding block 34 to the back surface of the sliding plate 41, the stability and accuracy of the displacement transmission assembly 40 are enhanced. The arrangement of the vertical sliding rail 33 and the vertical sliding block 34 provides a stable sliding path for the sliding plate 41, ensuring the accurate movement of the sliding plate 41 on the L-shaped plate 31, thereby improving the control accuracy and reliability of the entire displacement transmission assembly 40. The movement of the wedge-shaped block 43 drives the sliding plate 41 to slide up and down on the L-shaped plate 31 through the cooperation of the vertical sliding block 34 and the vertical sliding rail 33.

[0033] In some embodiments, the top of the side plate 32 is provided with a longitudinal sliding block 36, and a longitudinal sliding rail 35 is slidably arranged on the longitudinal sliding block 36, and the longitudinal sliding rail 35 is fixed to the bottom of the H-shaped plate 37. By arranging the longitudinal sliding block 36 on the top of the side plate 32, and slidably arranging the longitudinal sliding rail 35 thereon, and fixing the longitudinal sliding rail 35 to the bottom of the H-shaped plate 37, the stability and guiding accuracy of the displacement guiding assembly 30 are enhanced. The arrangement of the longitudinal sliding block 36 and the longitudinal sliding rail 35 provides a stable sliding path for the H-shaped plate 37, ensuring the accurate sliding of the H-shaped plate 37 on the side plate 32. The rotation of the swing arm 47 pushes the H-shaped plate 37 to slide along the longitudinal sliding rail 35. Since the longitudinal sliding rail 35 is fixed to the bottom of the H-shaped plate 37, and the longitudinal sliding block 36 slides on the top of the side plate 32, the sliding of the H-shaped plate 37 is more stable and accurate.

[0034] In some embodiments, the side away from each other of the two side plates 32 is fixedly provided with an ear plate 32a fixed to the top of the workbench 10. By fixedly arranging the ear plate 32a on the side away from each other of the two side plates 32, and fixing the ear plate 32a to the top of the workbench 10, the structural stability and rigidity of the entire displacement guiding assembly 30 are enhanced. The ear plate 32a serves as an additional support point, which helps to disperse and resist the forces and torques that may be generated during polishing, thereby reducing the deformation and vibration of the side plate 32. Since the ear plate 32a is fixed to the top of the workbench 10, it helps the side plate 32 to resist these forces, preventing unnecessary movement or deformation of the side plate 32.

[0035] In some embodiments, the two ends of the horizontal shaft 38 are provided with lifting blocks 38a fixed to the top of the H-shaped plate 37. The two ends of the horizontal shaft 38 are provided with lifting blocks 38a fixed to the top of the H-shaped plate 37. The main function of this design is to enhance the stability of the connection between the horizontal shaft 38 and the H-shaped plate 37, and to provide additional support to ensure that the H-shaped plate 37 can move stably during polishing, reducing vibration and deviation. The presence of lifting blocks 38a helps to evenly distribute the force acting on the H-shaped plate 37, thereby improving the rigidity and durability of the entire displacement guide assembly 30.

[0036] In some embodiments, the lower end of the swing arm 47 is fork-shaped and is provided with a guide wheel 48 installed through a rotating shaft, which slides along the slope of the wedge-shaped block 43. The lower end of the swing arm 47 is designed as a fork structure and is provided with a guide wheel 48 installed through a rotating shaft, which enables the guide wheel 48 to slide along the slope of the wedge-shaped block 43. The function of this technical feature is to provide a smooth and controllable sliding mechanism, ensuring the accuracy and stability of the swing arm 47 when pushing the H-shaped plate 37 to move. The design of the guide wheel 48 sliding along the slope of the wedge-shaped block 43 helps to reduce friction and wear, improving the service life and reliability of the entire displacement transmission assembly 40.

[0037] In some embodiments, the shell tool 50 includes a bearing seat 51 fixed above the H-shaped plate 37, and a longitudinal through thermos bottle shell groove 52 is formed above the bearing seat 51, and a clamping block 53 is arranged in the thermos bottle shell groove 52 to slide along the bottom of the groove. The side of the bearing seat 51 corresponding to the clamping block 53 is provided with an electric / gas push rod B 54, and the output end of the electric / gas push rod B 54 extends into the thermos bottle shell groove 52 and is fixed with the clamping block 53.

[0038] The design of the shell tool 50 includes a bearing seat 51 fixed above the H-shaped plate 37, and a longitudinal through thermos bottle shell groove 52 is formed above the bearing seat 51, and a clamping block 53 is arranged in the thermos bottle shell groove 52 to slide along the bottom of the groove. The side of the bearing seat 51 corresponding to the clamping block 53 is provided with an electric / gas push rod B 54, and the output end of the electric / gas push rod B 54 extends into the thermos bottle shell groove 52 and is fixed with the clamping block 53. The function of this design is to provide a precisely controlled clamping mechanism for stably fixing the thermos bottle shell to be processed, ensuring accurate positioning and stable clamping during polishing. When the thermos bottle shell needs to be polished, the electric / gas push rod B 54 is activated, and its output end pushes the clamping block 53 to slide along the bottom of the thermos bottle shell groove 52, thereby stably clamping the thermos bottle shell in the groove. The movement and positioning of the clamping block 53 are precisely controlled by the electric / gas push rod B 54, ensuring the stability and accuracy of the thermos bottle shell during polishing.

[0039] In some embodiments, the workbench 10 is vertically provided with a stand 21 extending to the upper and lower sides thereof, the upper front surface of the stand 24 is fixed to the back surface of the polishing conveyor belt 22, and the lower front surface of the stand 24 is fixedly provided with a motor 23; the output end of the motor 23 is drivingly connected to the input end of the side edge of the polishing conveyor belt 22 through a belt 24. By vertically extending the stand 21 to the upper and lower sides of the workbench 10, fixing the polishing conveyor belt 22 above the stand 21, and fixing the motor 23 below the stand 21, the stable operation of the polishing conveyor belt 22 is ensured.

In the conventional conveyor belt, at least two rotating rollers for drivingly connecting the conveyor belt are provided, and a central shaft is arranged on the rotating roller to rotate the rotating roller. In the present embodiment, the central shaft of the rotating roller is extended to the outside, and the belt is conveniently sleeved on the central shaft.

[0040] The output end of the motor 23 is drivingly connected to the input end of the side edge of the polishing conveyor belt 22 through the belt 24, so as to drive the movement of the polishing conveyor belt 22. When the outer shell of the thermos bottle needs to be polished, the outer shell of the thermos bottle is fixed on the outer shell tool 50, and the outer shell tool 50 drives the outer shell of the thermos bottle to longitudinally displace through the driving of the displacement transmission assembly 40, so that the port of the outer shell of the thermos bottle moves to the position abutting against the surface of the polishing conveyor belt 22. At this time, the abrasive on the polishing conveyor belt 22 polishes the port of the outer shell of the thermos bottle, and the polishing work is completed.
