Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a rubber ferrule installation device. Background Art

[0002] like Fig.12 As shown, a washing pipe 1 for use in a car (only a partial length of the washing pipe 1 is shown in the figure) needs to be pre-processed before being installed on the car, specifically, an elastic rubber ring 2 is installed at a predetermined position of the washing pipe 1, and at this time, the rubber ring 2 is a predetermined distance from the pipe opening 3 (i.e., the head end) of the washing pipe 1. The rubber ring 2 has two through-holes 4 for installation on the washing pipe 1, and the diameter of the installation opening 4 in the free state is smaller than the outer diameter of the washing pipe 1.

[0003] During installation, the pipe mouth 3 of the washing pipe 1 needs to pass through a mounting hole 4 of the rubber ring 2 and out. However, since the rubber ring 2 is elastic and easy to deform, and the aperture of the mounting hole 4 in the free state is smaller than the outer diameter of the washing pipe 1, the mounting hole 4 must be expanded before the washing pipe 1 can be passed through the mounting hole 4, which is very difficult to process, and there is a lack of special processing equipment on the market.

[0004] In addition, in order to install the rubber ferrule 2 at the predetermined position of the washing pipe 1, currently, it is mainly installed roughly by experienced personnel based on experience, and the consistency of product processing is relatively poor. In order to improve product consistency, some people use a ruler to measure the length of the rubber ferrule 2 from the pipe opening 3 of the washing pipe 1 while adjusting the position of the rubber ferrule 2 on the washing pipe 1. However, this method has extremely low processing efficiency and cannot be used in production at all. Summary of the invention

[0035] 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 indicating device 30 and a moving device 40.

[0036] Among them, the rubber ring installation device 20 is used to install the rubber ring 2 on the washing pipe 1; the positioning indicating 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 a 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.

[0037] The mounting platform 10 is in the shape of a flat plate and is used to be arranged on a workbench or a work table.

[0038] The moving device 40 is arranged on the mounting platform 10, and includes a moving driving cylinder 41, a moving guide rail 42 and a moving platform 43. In the present embodiment, two moving guide rails 42 are arranged, which extend in the horizontal direction on the upper surface of the mounting platform 10.

The moving driving cylinder 41 is arranged 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.

[0039] Figure 4 The three-dimensional structure diagram of the rubber ring installation device in the embodiment of the present invention is shown in FIG. Figure 1 ; Figure 5 The three-dimensional structure diagram of the rubber ring installation device in the embodiment of the present invention is shown in FIG. Figure 2 .

[0040] like Figure 1-Figure 5 As shown, the rubber ferrule installation device 20 is used to install the rubber ferrule 2 on the washing pipe 1, which is arranged on the moving platform 43 of the moving device 40 and can be moved under the drive of the moving device 40. The rubber ferrule installation device 20 includes a supporting mechanism 21 and at least three opening mechanisms. In this embodiment, three opening mechanisms are provided, which are respectively recorded as a first opening mechanism 22, a second opening mechanism 23, and a third opening mechanism 24. The first opening mechanism 22, the second opening mechanism 23, and the third opening mechanism 24 have the same structure, but are arranged at different positions.

[0041] The supporting mechanism 21 includes a horizontal mounting plate 211 , a first bracket 212 and a second bracket 213 .

[0042] like Figure 3As shown, the bottom of the horizontal mounting plate 211 is fixedly connected to the moving 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 moving platform 43 move along the moving guide rail 42.

[0043] like Figure 4 and Figure 5 As shown, the first bracket 212 is fixedly mounted on the horizontal mounting plate 211 and is in an inverted “T” shape. The first opening mechanism 22 is disposed on the first bracket 212 .

[0044] The second bracket 213 is fixedly arranged on the horizontal mounting plate 211 and is 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 on the horizontal mounting plate 211, and the third support mechanism 24 is arranged at the lower position of the vertical plate 2131. The reinforcing rib 2132 is vertically arranged 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 arranged on both sides of the second bracket 213.

[0045] The horizontal plate 2133 is disposed on the 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 .

[0046] The structure of the spreading mechanism is described in detail by taking the first spreading mechanism 22 as an example.

[0047] like Figure 4 and Figure 5 As shown, the first opening mechanism 22 is disposed 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 .

[0048] 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.

[0049] The opening member 221 is an L-shaped round rod with a smooth surface, and comprises a connecting rod portion 2211 connected to the moving member 2222 and an opening rod portion 2212 vertically connected to the connecting rod portion 2211. The connecting rod portion 2211 and the opening rod portion 2212 are vertical, and the opening member 221 is integrally formed.

[0050] The connecting rods 2211 of the first opening mechanism 22, the second opening mechanism 23, and the third opening mechanism 24 are located in the same vertical plane and are evenly distributed around an axis perpendicular to the vertical plane, and the opening rods 2212 of the three opening mechanisms are parallel to the axis. The opening rods 2212 of the three opening mechanisms have the same size, and the connecting rods 2211 of the three opening mechanisms also have the same size.

[0051] The connecting rod portion 2211 of each spreading portion forms an angle of 120° 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 an angle of 60° 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 an angle of 120° with the horizontal mounting plate 211.

[0052] Figure 6 is a schematic diagram of the rubber ring installation device in the embodiment of the present invention when its opening member 221 is in the closed position; Figure 7 1 is a schematic diagram of the rubber ring installation device in the embodiment of the present invention when its expansion member 221 is in the expansion position.

[0053] 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 portions 2211.

[0054] Figure 8 Schematic diagram of a rubber ring installed on a rubber ring installation device in an embodiment of the present invention.

[0055] like Figure 6-Figure 8 As shown, when the three expansion mechanisms are all located at their respective closed positions, the expansion rods 2212 of the three expansion members 221 can be attached to 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 installation opening 4. At this time, the installation opening 4 can be inserted into the three expansion members 221, specifically, into the expansion rods 2212 of the three expansion members 221.

[0056] Then, each driving unit 222 can drive the corresponding opening member 221 to move from its closed position to the opening position, thereby evenly opening the installation opening 4, and then inserting the washing pipe 1 into the opened installation opening 4.

[0057] 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.

[0058] Fig. 9 2 is a schematic diagram of the structure of the rubber ring installation device 20 and the positioning indication device 30 in an embodiment of the present invention; Fig.10 It is a schematic diagram of the three-dimensional structure of the positioning indicating device in an embodiment of the present invention.

[0059] like Figure 9-10 As shown, the positioning indicating device 30 is used to indicate the installation position of the rubber ring 2 on the washing pipe 1. The positioning indicating device 30 includes a mounting rail 31, an indicating stopper 32 and a mounting block 33.

[0060] like Figure 3 and Fig. 9 As shown, the mounting block 33 is fixedly arranged on the mounting platform 10. The mounting rail 31 is fixed on the mounting block 33, and is arranged in the horizontal direction and parallel to the open rod portion 2212. The mounting rail 31 is in the shape of a rectangular parallelepiped strip.

[0061] Fig.11 Schematic diagram of the structure of the indicating block in the embodiment of the present invention.

[0062] like Fig.10 and Fig.11 As shown, the indicating block 32 is arranged on the mounting rail 31 and is located on one side of the rubber ring mounting device 20. The indicating block 32 is used to block the head end of the washing pipe 1 during the process of passing the washing pipe 1 through the mounting opening 4 of the rubber ring 2 through the rubber ring mounting device 20, thereby indicating the installation position of the rubber ring 2 on the washing pipe 1. The indicating block 32 has a connecting portion 322 and an indicating portion 321.

[0063] 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.

[0064] like Figure 9-11 As shown, the indicating portion 321 is arranged on the connecting portion 322, and is used to block the head end of the washing pipe 1, so as to indicate the installation position of the rubber ring 2 on the washing pipe 1. The indicating portion 321 is in the shape of a rectangular parallelepiped, and its side close to the rubber ring installation device 20 serves as a blocking indicating surface 3211, and the blocking indicating surface 3211 is parallel to the vertical plane where the connecting rod portion 2211 is located, and is arranged opposite to all the spreading rod portions 2212. The top of the blocking indicating surface 3211 is higher than the spreading rod portion 2212 located at the highest point when in the spreading position, the bottom of the blocking indicating surface 3211 is lower than the spreading rod portion 2212 located at the lowest point when in the spreading position, and the width of the blocking indicating surface 3211 is greater than the interval between the spreading rod portions 2212 located at both sides when in the spreading position.

[0065] The use process of the rubber ring installation device 100 is as follows:

[0066] 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 piece 221 of the rubber ring installation device 20 and the indicating stopper 32 is adjusted by the moving device 40 .

[0067] Secondly, the driving units 222 of the three expansion structures of the rubber ring installation device 20 drive their respective expansion parts 221 to move to their respective closed positions, and then the installation 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 installation port 4, and then manually inserting the washing pipe 1 into the expanded installation port 4, so that the pipe mouth 3 of the washing pipe 1 is against the blocking indicating surface 3211 of the indicating block 32.

[0068] 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.

[0069] In this way, a washing pipe 1 with a rubber ring 2 installed at a predetermined position is obtained.

[0070] Functions and Effects of the Embodiments

[0071] According to the rubber ring installation equipment involved in this embodiment, because it includes a rubber ring installation device, the rubber ring installation device includes a supporting mechanism and at least three expansion mechanisms, the expansion mechanism is arranged on the supporting mechanism, the expansion mechanism at least includes an expansion member and a driving unit, the driving unit can drive the expansion member to switch between its closed position and the expansion position, the connection line between the expansion position and the closed position constitutes the movement trajectory of the expansion mechanism, the movement trajectory of all the expansion mechanisms is located in the same vertical plane and is evenly distributed around an axis perpendicular to the vertical plane, when all the expansion mechanisms are located at their respective closed positions, the installation ports can be inserted into all the expansion members, when all the expansion mechanisms move from their respective closed positions to their respective expansion positions, the expansion members can evenly expand the installation ports, at this time, the washing pipe can be easily passed through the expanded installation port, and then all the expansion mechanisms return to their respective closed positions, the rubber ring and the washing pipe can be removed together, so that a washing pipe with the rubber ring installed can be obtained.

[0072] Furthermore, because the rubber ring installation equipment also includes a positioning indication device, it can indicate the installation position of the rubber ring on the washing pipe, thereby ensuring that the rubber ring is installed at a predetermined position on the washing pipe, which not only improves the consistency of product processing, but also improves processing efficiency.

[0073] Furthermore, because the driving unit includes an expansion driving cylinder and a moving part, the output shaft of the expansion driving 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.

[0074] Furthermore, because the expansion member has a connecting rod portion connected to the movable 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, and all the expansion rod portions of the expansion mechanism 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.

[0075] Furthermore, because the expansion piece 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 piece together after processing.

[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 supporting mechanism includes: a horizontal mounting plate, a first bracket and a second bracket, the first bracket and the second bracket are both arranged on the horizontal mounting plate and are arranged at intervals, one opening mechanism is arranged on the first bracket, recorded as the first opening mechanism, and the other two opening mechanisms are arranged on the second bracket, recorded as the second opening mechanism and the third opening mechanism, respectively, the connecting rod portion of the first opening mechanism is at an angle of 60° with the horizontal mounting plate, the connecting rod portion of the second opening mechanism is perpendicular to the horizontal mounting plate, and the connecting rod portion of the third opening mechanism is at an angle of 120° with the horizontal mounting plate. This arrangement can not only realize the reliable installation of the three opening mechanisms, but also ensure that the subsequent opening cadres can evenly open the installation port 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] Furthermore, because the positioning indicating device includes an installation rail and an indicating block, the installation rail is arranged in the horizontal direction and is parallel to the support rod, and the indicating block is arranged on the installation rail and is located on one side of the rubber ring installation device, the indicating block blocks the head end (tube mouth) of the washing pipe during the process of passing the washing pipe through the rubber ring installation device on the installation port of the rubber ring, thereby indicating the installation position of the rubber ring on the washing pipe, ensuring that the rubber ring is finally installed at the predetermined position of the washing pipe.

[0080] Furthermore, because the side of the indicator portion close to the rubber ring installation device serves as a blocking indicator surface, the blocking indicator surface is parallel to the vertical plane where the connecting rod portion is located, and is arranged opposite to all the spreading rod portions. When the spreading rod portions are in their respective closed positions, they are aligned with the central position of the blocking indicator surface, the top of the blocking indicator surface is higher than the spreading rod portion at the highest point in the spreading position, the bottom of the blocking indicator surface is lower than the spreading rod portion at the lowest point in the spreading position, and the width of the blocking indicator surface is greater than the interval between the spreading rod portions at both sides in the spreading position. This arrangement ensures that the blocking indicator surface can play a role in blocking the pipe opening during the process of inserting the washing pipe into the rubber ring. Once the pipe opening reaches this position, the action of inserting the washing pipe can be stopped, and after all the spreading mechanisms are restored to their respective closed positions, the rubber ring and the washing pipe are removed together to obtain a washing pipe with the rubber ring installed at a predetermined position.

[0081] Furthermore, because the rubber ring installation equipment also includes a moving device, the moving device can drive the rubber ring installation device to move in a horizontal direction close to and away from the indicating block, so that it is convenient to adjust the distance between the spreader and the indicating block as needed, thereby changing the installation position of the rubber ring on the washing pipe to meet different processing requirements. For example, some require the rubber ring to be installed 12 cm away from the pipe mouth of the washing pipe, while others require the rubber ring to be installed 13 cm away from the pipe mouth of the washing pipe, and so on.

[0082] Furthermore, because the moving device includes a moving guide rail, a moving platform and a moving driving cylinder, the rubber ring installation device is arranged on the moving platform. The moving driving cylinder can drive the moving platform and the rubber ring installation device to move along the moving guide rail, thereby facilitating the rubber ring installation device to move in a horizontal direction close to and away from the indicating block.

[0083] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
