Description

Technical Field

[0001] This utility model relates to a positioning device for a cup body, and more particularly to an upper clamp structure with dustproof function for a cup body polishing machine. Background Technology

[0002] A thermos is generally a water container made of ceramic or stainless steel with a vacuum layer. It has a lid on top that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping the water warm. When manufacturing stainless steel thermoses, the body of the thermos needs to be polished. During the polishing process, the thermos needs to be held and fixed by clamps, which include a lower clamp and an upper clamp. The upper clamp moves up and down in conjunction with the lower clamp to hold and fix the thermos body.

[0003] For example, the feeding device of the dual-station cup polishing equipment disclosed in patent CN219649557U includes a base, a rotating table on the base, the rotating table being rotatably connected to the base along its own axis, a slide on the rotating table, and clamping mechanisms on both sides of the slide. The clamping mechanisms include two lower clamps and two upper clamps corresponding to the two lower clamps respectively. The two lower clamps are rotatably connected to the rotating table along their own axes. A slide rail is provided on the side wall of the slide, and a slider that cooperates with the slide rail is provided on the slide base. The slider is slidably connected to the slide rail and can move along the axial direction of the rotating table. A cylinder for driving the slide base to move is provided on the slide, and a rotating shaft is provided on the two upper clamps. The rotating shaft is rotatably connected to the slide base through bearings.

[0004] The existing cup polishing machine has exposed cylinders for driving the upper clamp lifting and rotating shafts. The slide block for mounting the rotating shaft is slidably connected to the slide rail via a slider. During use, dust in the outside air and polishing debris can easily enter the cylinder, rotating shafts, or between the slider and the slide rail, causing the machine to jam and affecting its normal operation.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0027] Figures 1-6 As shown, the cup polishing machine has a dustproof upper clamp structure, including a dustproof cover 2, a lifting drive 6, and a rotating shaft 3. The dustproof cover 2 has a cavity, and the lifting drive 6 and the rotating shaft 3 are located in the cavity. The rotating shaft 3 is connected to the lifting drive 6, and the lifting drive 6 can drive the rotating shaft 3 to move up and down. The rotating shaft 3 can rotate relative to the lifting drive 6 around the axis of the rotating shaft 3. The dustproof cover 2 has a through hole 13 that communicates with the cavity. The lower end of the rotating shaft 3 extends out of the through hole 13 and fits against the inner wall of the through hole 13. The upper clamp 4 is located outside the dustproof cover 2 and is connected to the lower end of the rotating shaft 3.

[0028] This patent uses a dust cover 2 to house the rotating shaft 3 and the lifting driver 6 for moving and clamping the upper clamp 4. The dust cover 2 has a through hole 13. The lower end of the rotating shaft 3 extends out of the through hole 13 and connects to the upper clamp 4. The rotating shaft 3 fits against the inner wall of the through hole 13. During the operation of the equipment, the dust cover 2 can prevent external dust or grinding debris from entering the rotating connection part of the lifting driver 6 or the rotating shaft 3. Only part of the rotating shaft 3 is exposed to the outside to drive the upper clamp 4 to move up and down, thereby ensuring the normal operation of the clamp.

[0029] A transition seat 21 is provided between the lifting drive 6 and the rotating shaft 3. The transition seat 21 is connected to the lifting drive 6, and the lifting drive 6 can drive the transition seat 21 to move up and down. A bearing 15 is installed on the transition seat 21, and the rotating shaft 3 is rotatably connected to the transition seat 21 through the bearing 15. The bearing 15 is used to rotatably connect the rotating shaft 3 and the transition seat 21 to reduce the resistance when the rotating shaft 3 rotates and improve the smoothness of rotation.

[0030] Figure 4 As shown, the adapter 21 has a hole 17 for installing the bearing 15, and the rotating shaft 3 is inserted into the hole 17 and connected to the bearing 15.

[0031] Preferably, the adapter 21 includes a base 8 and a second cover plate 9. A channel 17 is formed in the base 8. The two ends of the base 8 are provided with second openings 24 of the channel 17. The second cover plate 9 is fixedly connected to the upper end of the base 8 by bolts and covers the second opening 24 at the upper end. The second cover plate 9 is connected to the lifting drive 6. The rotating shaft 3 extends from the second opening 24 at the lower end of the base 8 into the channel 17 and is connected to the bearing 15.

[0032] Specifically, the middle of the channel 17 is provided with a first inner ring protrusion 16, and the upper and lower sides of the first inner ring protrusion 16 are abutted by bearings 15. The outer ring of the bearings 15 is connected to the inner wall of the channel 17. A retaining spring is snapped on the inner wall of the channel 17, and the retaining spring is limited below the bearings 15 installed on the lower side. The rotating shaft 3 is inserted into the channel 17 through the second opening 24 at the lower end. The rotating shaft 3 passes through the center of the bearings 15 on the upper and lower sides and is connected to the inner ring of the bearings 15. A retaining spring is snapped on the rotating shaft 3, and the retaining spring is limited above the bearings 15 installed on the upper side. The rotating shaft 3 is provided with a first step 14, and the first step 14 is limited below the bearings 15 installed on the lower side, so that the rotating shaft 3 is rotatably connected to the adapter 21.

[0033] The cavity includes a first cavity 10 for guiding the movement of the adapter 21, which is slidably housed within the first cavity 10. By slidably arranging the adapter 21 within the first cavity 10, the adapter 21, the rotating shaft 3, and the upper clamp 4 are made more stable when driven to move linearly, and the structure that fits and slides within a channel better prevents vibration during movement.

[0034] A sliding sleeve 11 is fixed inside the first cavity 10. The adapter seat 21 is slidably disposed inside the sliding sleeve 11. By setting the sliding sleeve 11, the smoothness of sliding can be improved, and the sliding sleeve 11 can also act as a wear-resistant sleeve, achieving a longer service life and being easy to replace.

[0035] The sliding sleeve 11 can increase the lubricating oil inside to improve the smoothness of the sliding of the adapter 21, and the structure of the dust cover 2 makes it difficult for the lubricating oil to leak out.

[0036] The cavity includes a second cavity 5, a lifting drive 6 is placed inside the second cavity 5, the upper end of the first cavity 10 is connected to the lower end of the second cavity 5, and the lower end of the first cavity 10 is provided with the aforementioned through hole 13.

[0037] Figure 5As shown, the dust cover 2 includes an upper shell 18, a lower shell 22, and a first cover plate 12. The upper shell 18 has a second cavity 5, and the lower shell 22 has a first cavity 10. The upper shell 18 and the lower shell 22 are assembled and fixedly connected by bolts. The lower shell 22 has a first opening at one end away from the upper shell 18. The first cover plate 12 covers the first opening and is fixed to the lower shell 22 by bolts. A through hole 13 is provided on the first cover plate 12.

[0038] Preferably, the first cavity 10 is a circular inner cavity and the adapter 21 is a cylinder, which makes it easier to assemble and use immediately. The adapter 21 is similar to a piston sliding in the first cavity 10.

[0039] Preferably, the lifting drive 6 includes a cylinder 19, which is fixed inside the dust cover 2. The adapter 21 is connected to the piston rod of the cylinder 19, and the extension and retraction of the piston rod controls the linear movement of the adapter 21. The cylinder 19 is fixedly installed inside the upper shell 18.

[0040] Figure 6 As shown, a connecting plate 7 is fixedly connected to the end of the piston rod, a guide post 20 is fixed on the connecting plate 7, a guide hole 23 is provided on the cylinder body of the cylinder 19 to slide with the guide post 20, and the second cover plate 9 is fixedly connected to the connecting plate 7.

[0041] The sliding fit between the guide hole 23 and the guide post 20 makes the piston rod extension and retraction of the cylinder 19 more stable and less prone to vibration.

[0042] The dust cover 2 is installed on the frame 1.
