Referring to fig. 1 and 2, a sealing sleeve press-fitting device 100 according to a preferred embodiment of the present invention includes a frame 110, a positioning member 120, and a press-fitting mechanism 130.

The frame 110 is a support and is typically formed of metal. Specifically, in the present embodiment, the frame 110 includes legs 111 and a bottom plate 112 supported by the legs 111. The bottom plate 112 and the legs 111 can be connected by screwing, welding, etc. The bottom plate 112 is generally a metal plate, and has high supporting strength and a flat surface, so as to facilitate installation and layout of the positioning member 120 and other components such as the press-fitting mechanism 130 thereon.

In addition, in other embodiments, in order to improve the mobility and flexibility of the gland press-fitting device 100, a running mechanism such as a roller or a universal wheel may be further provided on the supporting leg 111.

The positioning member 120 is disposed on the frame 110. Further, the spacer 120 is formed with a positioning portion 101 that carries the shaft-like workpiece 20. The positioning element 120 may be a metal block or plate, and the positioning portion 101 may be a slot or a cavity formed on the positioning element 120. The shaft-like workpiece 20 is generally cylindrical or conical, and the shaft-like workpiece 20 in this embodiment refers to a fuel injector of a diesel engine. Of course, other types of shaft workpieces 20 are equally suitable without conflict.

After the shaft-like workpiece 20 is placed in the positioning portion 101, positioning can be achieved. During the press mounting process of the sealing sleeve 30, the shaft workpiece 20 is stressed in the axial direction. Therefore, the positioning portion 101 can limit the axial direction of the shaft-like workpiece 20 at least, so as to prevent the shaft-like workpiece 20 from moving in the axial direction when the sealing sleeve 30 is pressed.

The press-fitting mechanism 130 is disposed on the frame 110 and spaced apart from the positioning member 120 in the first direction. As shown in fig. 1, the first direction refers to a horizontal direction, i.e., the press-fitting mechanism 130 and the positioning member 120 are spaced apart in the horizontal direction. The press-fitting mechanism 130 includes a press-fitting driving member 131 and a pressing head 132, and the pressing head 132 is in transmission connection with the press-fitting driving member 131 and can move along a first direction under the driving of the press-fitting driving member 131. Therefore, the pressing head 132 can move toward or away from the positioning member 120 in the first direction under the driving of the pressing driving member 131. The press-fitting driving member 131 may be an air cylinder, a linear motor, or a screw pair structure of a motor.

Ram 132 may be a cylindrical or block-like structure, typically formed of metal. The end surface of the ram 132 facing the positioning member 120 is formed with a receiving hole 102. In this embodiment, the ram 132 is cylindrical, and the receiving hole 102 is coaxial with the ram 132. The receiving bore 102 is adapted to receive the sealing boot 30. The receiving bore 102 is thus shaped and dimensioned to match the sealing sleeve 30 to be press fitted. Specifically, the sealing sleeve 30 is generally a cylindrical structure with an opening at one end, and is in a circular bowl shape, so the accommodating hole 102 can be a circular blind hole or a stepped hole. Since the sealing sleeve 30 generally has a truncated-cone-shaped bottom, in order to enable the inner contour of the receiving bore 102 to better match the outer wall of the sealing sleeve 30, in the present embodiment, the receiving bore 102 is a stepped bore.

Further, the positioning portion 101 is configured such that the shaft-like part located at the positioning portion 101 is disposed coaxially with the housing hole 102. That is, when the shaft-like part is positioned and located in the positioning portion 101, it will be coaxial with the accommodation hole 102. Moreover, since the sealing sleeve 30 is matched with the receiving hole 102, the sealing sleeve 30 inserted into the receiving hole 102 can be coaxial with the receiving hole 102. Therefore, after the sealing sleeve 30 is placed in the accommodating hole 102 and the shaft-like workpiece 20 is placed in the positioning portion 101, the sealing sleeve 30 and the shaft-like part can be coaxial.

The steps of mounting the gland 30 using the gland press-fitting device 100 described above are generally as follows:

firstly, the sealing sleeve 30 is placed in the containing hole 102, and the sealing sleeve 30 is ensured to be coaxial with the containing hole 102; then, the shaft workpiece 20, such as an oil injector, is placed in the positioning portion 101 and positioned, so that the shaft workpiece 20 is coaxial with the accommodating hole 102 and the sealing sleeve 30 in the accommodating hole 102; coating a circle of glycerol on the sealing part of the shaft workpiece 20; starting the press-fitting driving member 131, and pushing the pressing head 132 to advance towards the positioning member 120 until the sealing sleeve 30 in the accommodating hole 102 is press-fitted to the shaft-like workpiece 20; the press-fitting driving piece 131 is kept in a pressing state for a certain period of time (generally more than 5 seconds) to ensure that the bottom of the sealing sleeve 30 is close to the spigot of the shaft workpiece 20; finally, the press-fitting driving member 131 drives the ram 132 to reset, and the next gland 30 is ready to be press-fitted.

The receiving hole 102 is matched with the positioning member 120, so that the coaxiality of the sealing sleeve 30 and the shaft-type workpiece 20 can be ensured and can be continuously maintained in the press-fitting process. Due to the fact that the accommodating hole 102 limits the sealing sleeve 30, the sealing sleeve 30 can be prevented from being inclined due to extrusion in the press fitting process. Therefore, the above-described sealing boot press-fitting device 100 can effectively improve the mounting accuracy of the sealing boot 30. Moreover, the press-fitting process is driven by the press-fitting driving member 131, and the shaft-like workpiece 20 and the sealing sleeve 30 are manually pre-installed at the designated positions, so that the labor is saved, and the efficiency is improved.

During machining, there are often a plurality of shaft workpieces 20 that require shaft sealing. For example, during the assembly of a diesel engine, six injectors are required to be provided on the cylinder head. Therefore, in order to further improve the processing efficiency.

Referring to fig. 3, in the present embodiment, the positioning element 120 is a plurality of positioning elements 120, the positioning elements 120 are disposed at intervals along a second direction perpendicular to the first direction, the press-fitting mechanism 130 includes a plurality of pressing heads 132, and the pressing heads 132 are disposed at intervals along the second direction and correspond to the positioning elements 120 one by one.

As shown in fig. 1, the second direction refers to a direction perpendicular to the plane of the drawing sheet. The positioning members 120 can simultaneously fix a plurality of shaft parts, and the corresponding pressing heads 132 can accommodate the sealing sleeves 30, and the sealing sleeves 30 are pressed onto the shaft parts 20 in the corresponding positioning members 120 under the driving of the pressing driving member 121. That is, the gland press-fitting device 100 can simultaneously perform press-fitting of a plurality of gland bushes 30, so that the efficiency is further improved.

As shown in fig. 3, in this embodiment, the number of the positioning members 120 is 12, and the number of the pressing heads 132 included in the press-fitting mechanism 130 is also 12, so that the sealing sleeve press-fitting device 100 can simultaneously press-fit 12 sealing sleeves 30.

Further, in the present embodiment, the press-fitting mechanism 130 includes a plurality of press-fitting driving members 131 to respectively drive the plurality of press-fitting heads 132 to move along the first direction. That is, each ram 132 is driven by a separate press-fit drive 131.

As shown in fig. 3, the press-fitting mechanism 130 includes 12 press-fitting rams 132, and thus the press-fitting mechanism 130 also includes 12 press-fitting drivers 131. Since each ram 132 is driven by a separate press-fit driver 131, the power requirements for a single press-fit driver 131 are lower. Therefore, the volume of each press-fitting driving member 131 is also small. Moreover, the plurality of press-fitting driving members 131 can be distributed on the frame 110, which contributes to reducing the volume of the sealed cartridge press-fitting device 100 as a whole.

In addition, press-fitting drivers 131 typically employ air cylinders, and because of the lower power requirements for individual press-fitting drivers 131, the air supply to supply air to each press-fitting driver 131 is also less demanding. The pressure and volume of the air supply can be reduced to help further reduce the volume of the envelope press-fitting apparatus 100.

It should be noted that in other embodiments, multiple rams 132 may be driven simultaneously by the same press-fit driver 131. At this time, the press-fitting driving member 131 may be a high-power motor, and the output end of the motor and the plurality of pressing heads 132 are driven by a transmission mechanism.

Furthermore, in this embodiment, the press-fitting mechanism 130 further includes a supporting base 133 extending along the second direction, and the plurality of press-fitting driving members 131 are fixedly disposed on the supporting base 133.

Specifically, the support seat 133 can provide support for the plurality of press-fitting driving members 131. The press-fitting driving members 131 may be fixed to the supporting base 133 in advance, and then the supporting base 133 is mounted to the frame 110, so that the press-fitting driving members 131 can be mounted to the frame 110. In this manner, assembly of the seal cartridge press-fitting device 100 may be facilitated and the plurality of press-fitting drivers 131 may be advantageously maintained in alignment in the second direction. The supporting base 133 is generally a metal plate structure formed integrally. The support base 133 in this embodiment is L-shaped and has two perpendicular side walls, so as to facilitate installation with the frame 110 and the press-fitting driving member 131.

It should be appreciated that in other embodiments, the plurality of press-fit drives 131 may be mounted directly to the base plate 112 of the frame 110 by threaded fasteners.

In the present embodiment, the receiving holes 102 of at least two indenters 132 have different diameters. Different sizes of sealing sleeves 30, with different apertures of the receiving bore 102, may receive sealing sleeves 30 of different sizes. That is, the sealing sleeve press-fitting device 100 can press-fit a plurality of sealing sleeves 30 of different models at the same time, and has a wider application range.

Specifically, in this embodiment, the ram 132 is detachably mounted to the driving end of the press-fitting driving member 131.

The driving end of the press-fitting driving member 131 can perform linear feeding along the first direction, and directly drives the press head 132 to move along the first direction. Wherein the ram 132 may be coupled to the drive end of the press-fit driver 131 by a threaded fastener. In one aspect, the direct connection of the press-fit driving member 131 to the ram 132 may make it simpler, omitting the intermediate transmission structure. On the other hand, because the pressure head 132 can be dismantled, the pressure head 132 of different models can also be conveniently changed to promote the suitability of seal cover pressure equipment device 100.

The sealing boot press-fitting apparatus 100 is able to achieve the purpose of improving the mounting accuracy of the sealing boot 30, and one of the important reasons is that the positioning portion 101 is configured such that the shaft-like part located at the positioning portion 101 is disposed coaxially with the housing hole 102. The positioning element 120 can be configured in various ways to enable the shaft-like part located in the positioning portion 101 to be coaxially arranged with the accommodating hole 102. Such as:

referring to fig. 1 and fig. 2 again, in the present embodiment, the positioning portion 101 is elongated and disposed coaxially with the accommodating hole 102, and the positioning portion 101 is configured to be disposed coaxially with the shaft-like workpiece 20 located in the positioning portion 101.

Specifically, the accommodating hole 102 may be a continuous elongated groove, or may be formed by splicing a plurality of short and spaced grooves. The inner wall profile of the positioning part 101 is matched with the shaft workpiece 20. Therefore, before press fitting, the shaft-like workpiece 20 is only required to be placed in the positioning portion 101, so that the shaft-like workpiece 20 and the accommodating hole 102 are ensured to be coaxial, and the operation is more convenient.

It should be noted that in other embodiments, the positioning element 120 may also enable the shaft-like part located in the positioning portion 101 to be coaxially arranged with the receiving hole 102 in other manners. Such as:

the positioning member 120 may include two opened or clamped clamping arms, and a protrusion or a boss for positioning reference is disposed between the two clamping arms. The shaft workpiece 20 can be placed between and clamped by two clamping arms. Furthermore, when the shaft-like workpiece 20 is clamped, one of the clamping arms may abut against the projection or stud and thereby position the shaft-like part so that it is coaxial with the receiving hole 102.

Further, in this embodiment, the positioning element 120 includes a plurality of support plates 121 disposed at intervals along the first direction, each support plate 121 is provided with an arc-shaped groove 1211, and the arc-shaped grooves 1211 of the plurality of support plates 121 are disposed coaxially with the accommodating hole 102 to form the positioning portion 101.

Specifically, when the shaft-like workpiece 20 is placed on the positioning unit 101, it is supported by the plurality of arc-shaped grooves 1211. Since the surface of the shaft-like workpiece 20 is a circular arc surface, the inner wall of the arc-shaped groove 1211 can be matched with the surface shape of the shaft-like workpiece 20, thereby realizing the stable positioning of the shaft-like workpiece 20. Meanwhile, after the shaft workpiece 20 is placed in the positioning portion 101, the plurality of coaxially arranged arc-shaped slots 1211 can ensure that the shaft workpiece 20 is coaxial with the accommodating hole 102.

In addition, the outer wall of the shaft workpiece 20 is generally provided with a seam allowance, and the seam allowance can be abutted with the edge of the arc-shaped groove 1211, so that the shaft workpiece 20 is limited in the axial direction.

Further, in the present embodiment, the arc-shaped groove 1211 is semicircular, and the radius of the arc-shaped groove 1211 decreases from the end of the positioning portion 101 close to the pressing head 132 to the end far from the pressing head 132.

For some types of shaft workpieces 20, such as fuel injectors, the outer diameter decreases from the head to the tail. A sealing boot 30 is mounted to the head of the fuel injector. That is, when the fuel injector is positioned on the locating member 120, the head of the fuel injector is positioned toward the ram 132. Therefore, the outer diameter of the injector decreases in the direction from the end of the positioning portion 101 closer to the ram 132 to the end farther from the ram 132. At this time, the radii of the arc-shaped grooves 1211 on the plurality of support plates 121 are also set to decrease progressively, which enables better positioning of the injector.

In the sealing sleeve press-fitting device 100, before the sealing sleeve 30 is mounted, the sealing sleeve 30 is firstly placed in the accommodating hole 102, and the shaft-type workpiece 20 is placed in the positioning portion 101, so that the shaft-type workpiece 20 and the accommodating hole 102 are coaxially arranged. The sealing sleeve 30 is matched with the containing hole 102, so that the sealing sleeve 30 placed in the containing hole 102 can be coaxial with the containing hole 102. Then, the pressing head 132 is driven by the press-fitting driving member 131 to move toward the positioning member 120 in the first direction until the shaft-like workpiece 20 penetrates into the receiving hole 102, so as to press-fit the sealing sleeve 30 in the receiving hole 102 onto the shaft-like workpiece 20. The receiving hole 102 is matched with the positioning member 120 to ensure the coaxiality of the sealing sleeve 30 and the shaft-like workpiece 20, and the receiving hole 102 can prevent the sealing sleeve 30 from being inclined in the press-fitting process. Therefore, the above-described sealing boot press-fitting device 100 can effectively improve the mounting accuracy of the sealing boot 30.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
