[0032] Figure 1 This is a schematic diagram of the three-dimensional structure of the rubber ring installation device in the embodiment of the utility model Figure 1 ; Figure 2 This is a schematic diagram of the three-dimensional structure of the rubber ring installation device in the embodiment of the utility model Figure 2 ; Figure 3 It is a side view of the rubber ring installation device in an embodiment of the present utility model.

[0033] like Figure 1-Figure 3 As shown, this embodiment provides a rubber ring installation device 100 for installing an elastic rubber ring 2 at a predetermined position of a washing pipe 1. The rubber ring installation device 100 includes a mounting platform 10, a rubber ring installation device 20, a positioning indicator device 30, and a moving device 40.

[0034] Among them, the rubber ring installation device 20 is used to install the rubber ring 2 on the washing pipe 1; the positioning indication device 30 is used to indicate the installation position of the rubber ring 2 on the washing pipe 1; the moving device 40 is used to drive the rubber ring installation device 20 to move in the horizontal direction close to and away from the indicating block 32, thereby changing the distance between the rubber ring installation device 20 and the indicating block 32.

[0035] The mounting platform 10 is in the shape of a flat plate and is used to be placed on a workbench or a work table.

[0036] The moving device 40 is disposed on the mounting platform 10 and includes a moving drive cylinder 41, a moving guide rail 42, and a moving platform 43. In this embodiment, two moving guide rails 42 are provided, extending horizontally on the upper surface of the mounting platform 10. The two moving guide rails 42 are parallel to each other and spaced a certain distance apart. The moving platform 43 is movably mounted on the moving guide rails 42. The moving drive cylinder 41 is disposed on the mounting platform 10 and is used to drive the moving platform 43 and the rubber ring mounting device 20 to move along the moving guide rails 42.

[0037] Figure 4 This is a schematic diagram of the three-dimensional structure of the rubber ring installation device in the embodiment of the utility model Figure 1 ; Figure 5 This is a schematic diagram of the three-dimensional structure of the rubber ring installation device in the embodiment of the utility model Figure 2 .

[0038] like Figure 1-Figure 5 As shown, the rubber ferrule mounting device 20 is used to mount the rubber ferrule 2 on the washing pipe 1. It is mounted on the movable platform 43 of the movable device 40 and is movable under the influence of the movable device 40. The rubber ferrule mounting device 20 includes a support mechanism 21 and at least three expansion mechanisms. In this embodiment, three expansion mechanisms are provided, namely, a first expansion mechanism 22, a second expansion mechanism 23, and a third expansion mechanism 24.

[0039] The supporting mechanism 21 includes a horizontal mounting plate 211 , a first bracket 212 , and a second bracket 213 .

[0040] like Figure 3 As shown, the bottom of the horizontal mounting plate 211 is fixedly connected to the mobile platform 43, and one side is connected to the output shaft of the driving cylinder 41. The driving cylinder 41 pushes the horizontal mounting plate 211, so that the horizontal mounting plate 211 and the mobile platform 43 move along the moving guide rail 42.

[0041] like Figure 4 and Figure 5As shown, the first bracket 212 is fixedly mounted on the horizontal mounting plate 211 and is in an inverted T-shaped structure. The first expansion mechanism 22 is mounted on the first bracket 212 .

[0042] The second bracket 213 is fixedly mounted on the horizontal mounting plate 211 and spaced apart from the first bracket 212. The second bracket 213 includes a vertical plate 2131, a reinforcing rib 2132, and a horizontal plate 2133. The bottom of the vertical plate 2131 is fixed to the horizontal mounting plate 211, and the third support mechanism 24 is disposed below the vertical plate 2131. The reinforcing rib 2132 is vertically mounted on the horizontal mounting plate 211 and connected to the vertical plate 2131 to improve the stability of the vertical plate 2131. The vertical plate 2131 and the third support mechanism 24 are respectively disposed on either side of the second bracket 213.

[0043] The horizontal plate 2133 is disposed on an upper portion of the vertical plate 2131 and is perpendicular to the vertical plate 2131 . The second spreading mechanism 23 is disposed on the horizontal plate 2133 .

[0044] The structure of the spreading mechanism will be described in detail by taking the first spreading mechanism 22 as an example.

[0045] like Figure 4 and Figure 5 As shown, the first opening mechanism 22 is provided on the first bracket 212 and is used to open the mounting opening 4 of the rubber ring 2 so as to allow the washing pipe 1 to pass through. The first opening mechanism 22 includes an opening member 221 and a driving unit 222 .

[0046] The driving unit 222 includes an expansion driving cylinder 2221 and a moving member 2222. The output shaft of the expansion driving cylinder 2221 is connected to the moving member 2222, and the expansion member 221 is disposed on the moving member 2222. The expansion driving cylinder 2221 is a double-axis cylinder.

[0047] The expansion member 221 is a smooth L-shaped round rod having a connecting rod portion 2211 connected to the moving member 2222 and an expansion rod portion 2212 perpendicularly connected to the connecting rod portion 2211. The connecting rod portion 2211 and the expansion rod portion 2212 are perpendicular to each other, and the expansion member 221 is integrally formed.

[0048] The connecting rods 2211 of the first, second, and third expansion mechanisms 22, 23, and 24 are located in the same vertical plane and are evenly distributed around an axis perpendicular to the vertical plane. The expansion rods 2212 of the three expansion mechanisms are all parallel to the axis. The expansion rods 2212 of the three expansion mechanisms have the same dimensions, as do the connecting rods 2211 of the three expansion mechanisms.

[0049] The connecting rod portion 2211 of each spreading mechanism forms a 120° angle with the adjacent connecting rod portion 2211 in the vertical plane. In this embodiment, the connecting rod portion 2211 of the first spreading mechanism 22 forms a 60° angle with the horizontal mounting plate 211, the connecting rod portion 2211 of the second spreading mechanism 23 is perpendicular to the horizontal mounting plate 211, and the connecting rod portion 2211 of the third spreading mechanism 24 forms a 120° angle with the horizontal mounting plate 211.

[0050] Figure 6 1 is a schematic diagram of the rubber ring installation device in an embodiment of the present invention when its expansion member 221 is in a closed position; Figure 7 1 is a schematic diagram of the rubber ring installation device in an embodiment of the present invention when its expansion member 221 is in the expansion position.

[0051] like Figure 6-Figure 7 As shown, the driving unit 222 can correspondingly drive the expansion member 221 to switch between its closed position and the expansion position. The connecting line between the expansion position and the closed position constitutes the moving trajectory of the expansion mechanism. The moving trajectories of the three expansion mechanisms coincide with the length direction of their respective connecting rod parts 2211.

[0052] Figure 8 This is a schematic diagram of a rubber ring placed on the rubber ring mounting device in an embodiment of the present invention.

[0053] like Figure 6-Figure 8 As shown, when the three expansion mechanisms are all in their respective closed positions, the expansion rods 2212 of the three expansion members 221 can be in contact with each other, or there can be a certain gap between them, as long as the outermost dimensions of the three expansion rods 2212 are smaller than the inner diameter of the mounting opening 4. At this time, the mounting opening 4 can be inserted into the three expansion members 221, specifically, into the expansion rods 2212 of the three expansion members 221.

[0054] Then, each driving unit 222 can drive the corresponding expansion member 221 to move from its closed position to the expansion position, thereby evenly expanding the installation opening 4, and then inserting the washing pipe 1 into the expanded installation opening 4.

[0055] Then, each driving unit 222 drives the corresponding opening member 221 to move from its opening position to the closing position, and the washing pipe 1 with the rubber ring 2 installed can be manually removed.

[0056] Figure 9 1 is a schematic structural diagram of the rubber ring installation device 20 and the positioning indicator device 30 in an embodiment of the present utility model; Figure 10 It is a schematic diagram of the three-dimensional structure of the positioning indicator device in the embodiment of the utility model.

[0057] like Figure 9-10As shown, the positioning indicator 30 is used to indicate the installation position of the rubber ring 2 on the washing pipe 1. The positioning indicator 30 includes a mounting guide rail 31, an indicator block 32 and a mounting block 33.

[0058] like Figure 3 and Figure 9 As shown, the mounting block 33 is fixedly mounted on the mounting platform 10. The mounting rail 31 is fixed to the mounting block 33, and is arranged in a horizontal direction and parallel to the support rod portion 2212. The mounting rail 31 is in the shape of a rectangular parallelepiped.

[0059] Figure 11 It is a structural schematic diagram of the indicating block in the embodiment of the present utility model.

[0060] like Figure 10 and Figure 11 As shown, an indicator block 32 is provided on the mounting rail 31 and is located on one side of the rubber ferrule mounting device 20. The indicator block 32 is used to block the head end of the washing pipe 1 during the process of inserting the washing pipe 1 into the mounting opening 4 of the rubber ferrule 2 through the rubber ferrule mounting device 20, thereby indicating the installation position of the rubber ferrule 2 on the washing pipe 1. The indicator block 32 includes a connecting portion 322 and an indicating portion 321.

[0061] The connecting portion 322 is sleeved on the mounting rail 31 and is detachably connected to the mounting rail 31 by bolts. Threaded holes are respectively provided on both sides of the connecting portion 322, and the bolts are tightened on the mounting rail 31 through the threaded holes.

[0062] like Figures 9-11 As shown, the indicator portion 321 is provided on the connecting portion 322 and is used to block the head end of the washing pipe 1, thereby indicating the installation position of the rubber ring 2 on the washing pipe 1. The indicator portion 321 is rectangular in shape, and its side close to the rubber ring installation device 20 serves as a blocking indicator surface 3211. The blocking indicator surface 3211 is parallel to the vertical plane on which the connecting rod portion 2211 is located and is arranged opposite all the expansion rod portions 2212. The top of the blocking indicator surface 3211 is higher than the expansion rod portion 2212 at the highest point in the expansion position, and the bottom of the blocking indicator surface 3211 is lower than the expansion rod portion 2212 at the lowest point in the expansion position. The width of the blocking indicator surface 3211 is greater than the distance between the expansion rod portions 2212 on both sides in the expansion position.

[0063] The process of using the rubber ring installation device 100 is as follows:

[0064] First, according to the predetermined distance between the rubber ring 2 and the pipe opening 3 (ie, the head end) of the washing pipe 1 , the distance between the expansion member 221 of the rubber ring installation device 20 and the indicator block 32 is adjusted by the moving device 40 .

[0065] Secondly, the driving units 222 of the three expansion structures of the rubber ring mounting device 20 drive their respective expansion parts 221 to move to their respective closed positions, and then the mounting port 4 of the rubber ring 2 is manually inserted into the three expansion parts 221, and then the driving units 222 of the three expansion structures drive the corresponding expansion parts 221 to move from their closed positions to the expansion positions, thereby evenly expanding the mounting port 4, and then manually inserting the washing pipe 1 into the expanded mounting port 4, so that the pipe mouth 3 of the washing pipe 1 rests on the blocking indication surface 3211 of the indicating block 32.

[0066] Then, each driving unit 222 drives the corresponding opening member 221 to move from its opening position to the closing position, and the washing pipe 1 with the rubber ring 2 installed can be manually removed.

[0067] In this way, the washing pipe 1 with the rubber ring 2 installed at the predetermined position is obtained.

[0068] Functions and Effects of the Embodiments

[0069] According to the rubber ring installation device involved in this embodiment, because it includes a supporting mechanism and at least three stretching mechanisms, the stretching mechanism is arranged on the supporting mechanism, and the stretching mechanism at least includes a stretching member and a driving unit. The driving unit can drive the stretching member to switch between its closed position and the stretching position. The connecting line between the stretching position and the closed position constitutes the moving trajectory of the stretching mechanism. The moving trajectories of all the stretching mechanisms are located in the same vertical plane and are evenly distributed around an axis perpendicular to the vertical plane. When all the stretching mechanisms are located in their respective closed positions, the installation ports can be inserted into all the stretching members. When all the stretching mechanisms move from their respective closed positions to their respective stretching positions, the stretching members can evenly stretch the installation ports. At this time, the washing pipe can be easily passed through the stretched installation port, and then all the stretching mechanisms return to their respective closed positions, and the rubber ring and the washing pipe can be removed together, thereby obtaining a washing pipe with the rubber ring installed.

[0070] Furthermore, because the driving unit includes an expansion drive cylinder and a moving part, the output shaft of the expansion drive cylinder is connected to the moving part, and the expansion part is arranged on the moving part, it is convenient to realize the movement of the expansion part between its expansion position and closing position.

[0071] Furthermore, because the driving cylinder for expansion is a double-axis cylinder, the accuracy of the movement of the expansion member is guaranteed.

[0072] Furthermore, because the expansion member has a connecting rod portion connected to the moving member and an expansion rod portion vertically connected to the connecting rod portion, all the connecting rod portions of the expansion mechanism are located in the same vertical plane and are evenly distributed around an axis perpendicular to the vertical plane. The expansion rod portions of all the expansion mechanisms are parallel to the axis. Therefore, it is only necessary to move along the extension direction of the connecting rod to achieve uniform expansion of the rubber ring after the expansion rod portion is inserted into the installation port.

[0073] Furthermore, because the expansion member is an L-shaped round rod with a smooth surface, it is easy to remove the rubber ring and the washing pipe from the expansion member after processing.

[0074] Furthermore, because all the spreading rods have the same size, all the connecting rods have the same size, which ensures that the spreading member spreads the rubber ring evenly.

[0075] Furthermore, since the expansion member is integrally formed, it is easy to process and form.

[0076] Furthermore, because there are three expansion mechanisms, the angle between the connecting rod portion of each expansion portion and the adjacent connecting rod portion is 120°. When the expansion member is in its closed position, its expansion rod portion is in contact with the expansion rod portion of the adjacent expansion member, which can simplify the structure of the device while achieving uniform expansion of the rubber ring.

[0077] Furthermore, because the support mechanism includes: a horizontal mounting plate, a first bracket, and a second bracket, the first bracket and the second bracket are both mounted on the horizontal mounting plate and spaced apart from each other, one expansion mechanism is mounted on the first bracket, referred to as the first expansion mechanism, and the other two expansion mechanisms are mounted on the second bracket, referred to as the second expansion mechanism and the third expansion mechanism, respectively. The connecting rod of the first expansion mechanism forms a 60° angle with the horizontal mounting plate, the connecting rod of the second expansion mechanism is perpendicular to the horizontal mounting plate, and the connecting rod of the third expansion mechanism forms a 120° angle with the horizontal mounting plate. This arrangement not only ensures the reliable installation of the three expansion mechanisms, but also ensures that the subsequent expansion mechanism can evenly expand the mounting opening to allow the washing pipe to pass through.

[0078] Furthermore, because the second bracket includes a vertical plate, a reinforcing rib and a horizontal plate, it is convenient to achieve stable installation of the second spreading mechanism and the third spreading mechanism.

[0079] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
