Description

Technical Field

[0001] This utility model relates to the field of thermos cup processing equipment, and in particular to a cup body fixing mechanism for thermos cup processing. Background Technology

[0002] The thermos cup fixing mechanism is a key piece of equipment used to stably clamp and position the cup body during the thermos cup production process (such as welding, polishing, spraying, printing, etc.). Its core function is to ensure that the cup body maintains a fixed posture during processing, and to avoid the decrease in processing accuracy, surface quality defects or poor finished products caused by displacement, shaking or deformation.

[0003] In existing technologies, such as the clamping mechanism for processing thermos cups disclosed in CN221817982U, there are upper mold components and lower mold components that can be separated from each other. The upper mold component can fix various non-standard upper heads using a locking sleeve, so there is no need to spare molds of various specifications. Since the upper head is fixed by locking with a nut, it is very convenient to replace. At the same time, each component can be precision machined to ensure the fitting accuracy of each component. By designing a centering clamping component, other parts to be assembled can be quickly loaded or unloaded, while ensuring the assembly accuracy of the parts to be assembled with the centering clamping component. The centering clamping component can rotate in both directions and never loosen.

[0004] However, it has some shortcomings. For example, when clamping and fixing thermos cups with a relatively high body, the center of gravity of the thermos cup may shift due to the excessive height of the cup. As a result, it cannot fix thermos cups of different heights. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cup body fixing mechanism for thermos cup processing that can fix and limit the position of thermos cups of different heights.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cup body fixing mechanism for processing thermos cups, including a mounting base; a support column, the support column being mounted on the mounting base, and the outer wall of the support column having external threads; a placement platform, the placement platform being sleeved on the support column, the inner wall of the placement platform having internal threads, and the placement platform being screwed to the support column; and a pneumatic inner clamp, the pneumatic inner clamp being mounted on the top of the support column, both the mounting base and the support column having ventilation chambers communicating with the air inlet chamber of the pneumatic inner clamp, the ventilation chambers being connected to an air supply device, the diameter of the pneumatic inner clamp being smaller than the diameter of the placement platform, and the pneumatic inner clamp being located inside the cup body when working.

[0007] A further preferred embodiment of this utility model is as follows: the pneumatic internal clamp includes a connecting column, which is installed on the top of a support column. The air inlet chamber is opened in the connecting column, and the bottom of the air inlet chamber passes through the bottom of the connecting column and communicates with the ventilation chamber on the support column. Multiple piston holes communicating with the air inlet chamber are opened laterally and evenly on the outer wall of the connecting column. A piston rod is provided, and multiple piston rods are provided. The multiple piston rods are slidably installed in the piston holes. A clamping plate with an arc-shaped outer wall is provided at the end of the piston rod away from the ventilation chamber.

[0008] A further preferred embodiment of this utility model is as follows: the placement platform has at least two screw holes, each screw hole is provided with a screw rod, the screw rod passes through the placement platform and abuts against the outer wall of the support column, and the screw rod is provided with a knob at the end away from the support column.

[0009] A further preferred embodiment of this utility model is that a protective pad is provided on the top of the pneumatic inner clamp.

[0010] A further preferred embodiment of this utility model is as follows: multiple mounting grooves are provided on the outer wall of the connecting column, the piston holes are respectively located in the mounting grooves, and a fixing plate is detachably provided in each mounting groove. The fixing plate is provided with a through hole for the piston rod to pass through, and the diameter of the through hole is smaller than the diameter of the piston hole.

[0011] A further preferred embodiment of this utility model is that the connecting column, the supporting column, and the mounting base are integrally formed.

[0012] A further preferred embodiment of this utility model is that the fixing plate is a separate unit.

[0013] Compared with the prior art, the advantage of this utility model is that when fixing cups of different heights, the placement platform is first rotated according to the length of the cup, so that the placement platform moves up or down on the support column until the bottom of the cup can be located on the placement platform when the cup is on the pneumatic inner clamp. At the same time, the pneumatic inner clamp is used to fix the cup, thus improving the application range of the fixing mechanism. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] This embodiment mainly describes the structure of a cup body fixing mechanism for processing thermos cups, as detailed below:

[0024] like Figures 1-5As shown, a cup body fixing mechanism for thermos cup processing includes a mounting base 1, a support column 2 mounted on the mounting base 1, and a pneumatic inner clamp 4 mounted on the top of the support column 2. To ensure the normal operation of the pneumatic inner clamp 4, a venting chamber 8 communicating with the air inlet chamber 42 of the pneumatic inner clamp 4 is provided in both the mounting base 1 and the support column 2. The venting chamber 8 is connected to an air supply device, allowing the air supply device to control the operation of the pneumatic inner clamp 4 (the air supply device is a bidirectional air supply pump, such as a piston pump, in the prior art; when the air supply device blows air, the pneumatic inner clamp 4 fixes the cup body, and when the air supply device inhales air, the pneumatic inner clamp 4 releases its fixation on the cup body). Therefore, when fixing the thermos cup body, the cup body is inserted into the pneumatic inner clamp 4 through its open end, and then the air supply device is activated to make the pneumatic inner clamp 4 support and abut against the inner wall of the cup body, thus achieving the fixing of the thermos cup body. To improve the stability of the cup on the pneumatic inner clamp 4, a placement platform 3 with a diameter larger than that of the pneumatic inner clamp 4 is fitted onto the support column 2. This ensures that when the cup is inserted into the pneumatic inner clamp 4, the bottom of the cup rests on the placement platform 3. To enable the fixing mechanism to secure cups of different lengths, external threads are provided on the outer wall of the support column 2, and internal threads are provided on the inner wall of the placement platform 3. The placement platform 3 is screwed to the support column 2. This allows the placement platform 3 to move up or down along the support column 2 when rotated. Therefore, when fixing cups of different heights, the placement platform 3 is first rotated according to the length of the cup, moving up or down on the support column 2 until the bottom of the cup rests on the placement platform 3 when on the pneumatic inner clamp 4. The pneumatic inner clamp 4 then secures the cup, thus expanding the applicability of the fixing mechanism.

[0025] Furthermore, in order to ensure the stability of the placement platform 3 on the support column 2, at least two screw holes 31 are opened in the placement platform 3, and a screw 5 is provided in each screw hole 31. The screw 5 can penetrate the placement platform 3 and abut against the outer wall of the support column 2. This ensures the stability of the placement platform 3 on the support column 2. At the same time, in order to facilitate the turning of the screw 5, a knob 6 is provided at the end of the screw 5 away from the support column 2.

[0026] Furthermore, to prevent the top of the pneumatic inner clamp 4 from scratching the inner wall of the cup when the cup body is on the pneumatic inner clamp 4, a rubber pad 7 is provided on the top of the pneumatic inner clamp 4.

[0027] The pneumatic internal clamp 4 includes a connecting column 41 mounted on the top of the support column 2, and an air inlet chamber 42 is opened in the connecting column 41. The bottom of the air inlet chamber 42 passes through the bottom of the connecting column 41 and communicates with the venting chamber 8 on the support column 2. Then, multiple piston holes 43 communicating with the air inlet chamber 42 are opened laterally and evenly on the outer wall of the connecting column 41. At the same time, a piston rod 44 is slidably arranged in each of the multiple piston holes 43, and a clamping plate 45 with an arc-shaped outer wall is provided at the end of the piston rod 44 away from the venting chamber 8. When the gas supply device supplies gas, the gas can push the piston rod 44 to move outward. As the piston rod 44 moves, the clamping plate 45 also moves, so that the clamping plate 45 can press against the inner wall of the cup. In order to prevent the clamping plate 45 from scratching the inner wall of the cup, a rubber protective layer is provided on the clamping plate 45. When the gas supply device draws in gas, the piston rod 44 retracts into the piston hole 43. At this time, the clamping plate 45 no longer presses against the inner wall of the cup, so the cup can be removed from the pneumatic inner clamp 4.

[0028] Furthermore, to facilitate the replacement of the piston rod 44, multiple mounting slots 46 are provided on the outer wall of the connecting column 41, and the piston hole 43 is located in each mounting slot 46. A fixing plate 47 is provided in each mounting slot 46 and is detachably connected to the mounting slot 46 by a bolt assembly. At the same time, a through hole 48 is provided on the fixing plate 47 for the piston rod 44 to pass through, and the diameter of the through hole 48 is smaller than the diameter of the piston hole 43. In this way, the fixing plate 47 can prevent the piston rod 44 from disengaging from the piston hole 43. When replacing the piston rod 44, the fixing plate 47 is removed from the mounting slot 46, and the piston rod 44 can be removed from the piston hole 43, which facilitates the replacement of the piston rod 44.

[0029] Furthermore, to facilitate the installation of the fixing plate 47, the fixing plate 47 is a separate unit.

[0030] Furthermore, to facilitate the strength of the fixing mechanism, the connecting column 41, the support column 2, and the mounting base 1 are integrally formed.
