Description

Technical Field

[0001] The invention relates to a terminal quick-change device of a robot working in a high-temperature environment, and in particular to a robot quick-change device of a water cooling system. Background Art

[0002] The existing robot end quick change device does not involve high temperature problems because the normal working environment is -10°C~50°C. In addition, the quick change device body is made of metal aluminum alloy and has sealing rings inside. These can only work stably under normal temperature conditions. However, if it works under high temperature conditions, it will cause the body to deform, the sealing ring to age prematurely or fail directly, and other components will also fail due to high temperature, causing the quick change device to fail and fail to work. Our company designed the present invention to address this defect. Summary of the invention

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1.

[0030] 2. The first fixing part is fixedly installed in the first groove and sleeved on the first movable part, the radial dimension of the inner wall of the first sealing part A becomes smaller, the third movable part is sleeved on the third fixing part, and the radial dimension of the inner wall of the third sealing part A becomes larger. The first and third fixing parts limit the first and third movable parts to prevent the first and third movable parts from being separated from the corresponding upper valve body and lower valve body. At the same time, under the action of the corresponding first and third springs, when the upper valve body and the lower valve body are separated, the first and third springs reset the first and third movable parts to form a seal.

[0031] 3. The design that the first sealing part and the third sealing part A, and the first sealing part A and the third sealing part have the same slope and are on the same inclined line as the radial dimension decreases can effectively avoid the problem of residual cooling water resulting from the formation of a step between the two due to inconsistent dimensions.

[0032] 4. The cylindrical and truncated cone structures are easy to process and easy to seal without any dead corners.

[0033] 5. The screws pass through the bottom of the lower valve body and are fixedly connected to the connecting column. The screws and the bottom of the lower valve body are sealed together. The method of passing the screws through the bottom of the lower valve body and fixing them with the connecting column is convenient for installing the connecting column and is also easy to seal. It is only necessary to perform sealing with a sealing ring at the fitting position between the screw and the lower valve body. If the fixing parts corresponding to the connecting column are directly fixed in the lower valve body, processing is inconvenient. If the lower valve body adopts an assembled type, the sealing parts need to be increased and expanded, which is inconvenient for production.

[0034] 6. A sealing ring installation groove is provided on the upper end surface of the third and fourth movable parts or the lower end surface of the first and second fixed parts. A sealing ring is installed in the sealing ring installation groove. When the upper valve body and the lower valve body are in contact, the sealing ring plays a buffering and sealing role to prevent water from flowing out from the gap between the upper valve body and the lower valve body at the moment of collision, destroying the production environment and causing product damage.

[0035] 7. The first seal and the main plate are fixedly connected by a plurality of screws, a part of which is located on the inner side of the area surrounded by the two coaxial first annular grooves, and another part is located on the outer side of the area surrounded by the two coaxial first annular grooves, so as to avoid the screws passing through the cooling water path, causing water leakage or requiring additional sealing at the screws, which would increase the cost.

[0088] The fourth passage includes a fourth groove and a fourth through hole arranged on the side of the lower valve body, the fourth through hole is connected to the fourth groove, the movable part of the fourth sealing member is a fourth movable part, the fixed part of the fourth sealing member is a fourth fixed part, the fourth movable part includes a fourth spring and a fourth movable column, the fourth movable column includes a fourth matching part and a fourth sealing part used to form a seal with the fourth fixed part, one end of the fourth spring is installed at the bottom of the fourth groove, and the other end is installed on the fourth matching part, one end of the fourth sealing part is a fourth connecting end connected to the fourth matching part, and the other end is a fourth free end used to form a press-fit relationship with the second fixed part of the second sealing member, the fourth connecting section points in the direction of the fourth free end, and the radial size of the fourth sealing part becomes larger;

[0089] The fourth movable member is sleeved on the fourth fixing member, the fourth fixing member is fixedly installed in the fourth groove, the fourth fixing member has a fourth sealing portion A matched with the fourth sealing portion, the fourth connecting section points in the direction of the fourth free end, and the radial dimension of the inner wall of the fourth sealing portion A becomes larger;

[0090] The second sealing portion and the fourth sealing portion A, and the second sealing portion A and the fourth sealing portion have the same slope in which the radial dimensions decrease and are on the same slope.

[0091] Wherein, the first and second matching parts are cylindrical, the first and second sealing parts are truncated cones, and the first and second sealing parts A corresponding to the first and second fixing parts are the inner walls constituting the truncated cone-shaped hole;

[0092] The third and fourth matching parts are cylinders with upper and lower through holes, the third and fourth sealing parts are cylinders with upper and lower through inverted truncated cone holes, the third and fourth fixing members are inverted truncated cone-shaped cylinders, and the third and fourth sealing members A are the outer walls of the third and fourth fixing members.

[0093] The cylindrical and truncated cone structures are easy to process on the one hand, and easy to seal on the other hand, without any sealing dead corners.

The method of passing the screw through the bottom of the lower valve body and fixing it with the connecting column is convenient for installing the connecting column and is also easy to seal. It is only necessary to perform sealing with a sealing ring at the fitting position of the screw and the lower valve body. If the fixing part corresponding to the connecting column is directly fixed in the lower valve body, processing is inconvenient. If the lower valve body adopts an assembled type, the sealing part needs to be increased and expanded, which is inconvenient for production.
