Description

Technical Field

[0001] The present disclosure belongs to the technical field of mechanical equipment assembly, and in particular relates to an assembly device for stacked components. Background Art

[0002] Stacked components are elongated components formed by stacking multiple sheet-like components in a certain pattern and axially threading them together through a rod-like component (such as a screw or polished rod). For example, a stacked component may include a rod-like component and multiple sheet-like components stacked along its length, with each sheet-like component interfering with the rod-like component. The sheet-like components may be thin sheets with rectangular holes inside. Rod-like components are rods with a rectangular cross-section.

[0003] In related technologies, in order to meet product requirements, when assembling sheet parts on rod-shaped parts, the rod-shaped parts are usually fixed first, and then the sheet parts are pushed onto the rod-shaped parts one by one through air pressure or hydraulic devices, so that each sheet part can be interference fit with the rod-shaped part.

[0004] However, when the sheet-like parts are thin workpieces, they are easily deformed under the push of a hydraulic or pneumatic device, thereby affecting the accuracy of the stacked components finally assembled. Summary of the Invention

[0007] In another embodiment of the present disclosure, the force-applying unit includes a first pressure head and a power component, one end of the power component is in contact with the first pressure head, and the other end of the power component is connected to the seat body; the side of the first pressure head away from the power component is toward the rod-shaped part, and the first pressure head is in sliding engagement with the seat body.

[0008] In another embodiment of the present disclosure, the first pressure head includes a pressing block and two limit plates, and the pressing block abuts against the power component; the two limit plates are arranged at intervals along a third direction on opposite sides of the pressing block, and the two limit plates are connected to the pressing block and along the first direction, and both ends of each limit plate protrude outside the pressing block, and a slide groove for accommodating the seat body is formed between the two limit plates and the pressing block, and the extension direction of the slide groove is the second direction, and the third direction is perpendicular to the first direction and the second direction respectively.

[0009] In another embodiment of the present disclosure, the tightening unit includes a second pressing head and a tightening component. Along the second direction, the opposite ends of the tightening component are in contact with the second pressing head and the base body respectively; one end of the second pressing head away from the tightening component is in contact with the rod-shaped part, and the second pressing head is in sliding cooperation with the base body.

[0010] In yet another implementation of the present disclosure, the second pressure head and the first pressure head are symmetrically arranged, and the symmetry axes of the second pressure head and the first pressure head extend along the first direction.

[0011] In another embodiment of the present disclosure, the seat body includes an outer frame, an upper limit block and a lower limit block, and the accommodating cavity is located in the middle of the outer frame; the upper limit block and the lower limit block are arranged at intervals along the first direction and are partially located in the accommodating cavity, and the upper limit block and the lower limit block are respectively connected to the outer frame; the side of the upper limit block facing the lower limit block and the side of the lower limit block facing the upper limit block are respectively used to clearance-match with the rod-shaped part.

[0012] In another embodiment of the present disclosure, the upper limit block includes a main body and a protrusion; the protrusion is located on the side of the main body facing the lower limit block and is connected to the main body, and along the second direction, the opposite side walls of the protrusion respectively form a slot with the main body for accommodating the tightening unit and the partial structure of the force-applying unit.

[0013] In yet another implementation of the present disclosure, the lower limiting block and the upper limiting block are arranged symmetrically, and the axis of symmetry between the lower limiting block and the upper limiting block extends along the second direction.

[0014] In another embodiment of the present disclosure, the assembly device further includes a sliding component connected to the base body, and the sliding component is used to drive the base to move along a third direction, and the third direction is perpendicular to the first direction and the second direction respectively.

[0016] The technical solutions provided by the embodiments of the present disclosure have the following beneficial effects:

[0017] When a sheet-like part is assembled on a rod-like part by using the assembly device provided by the embodiment of the present disclosure, since the assembly device includes a base body and the interior of the base body has a receiving cavity, the rod-like part can be placed in the receiving cavity of the assembly device first, and then the sheet-like part can be pre-assembled on the outer sleeve of the rod-like part.

[0018] Because the assembly device also includes a pressing assembly, which includes a force-applying unit and a tightening unit, the force-applying unit can apply a force along the second direction to the rod-shaped component to increase the gap between the sheet component and the rod-shaped component in the second direction for inserting the interference piece. This increased gap facilitates the insertion of the interference piece between the rod-shaped component and the sheet component, achieving an interference fit between the sheet component and the rod-shaped component through the interference piece, thereby avoiding the deformation that occurs when the sheet component is pressed into place outside the rod-shaped component as in the related art.

[0019] Furthermore, since the two opposite side walls of the rod-shaped part in the first direction respectively cooperate with the clearance of the seat body, when the force-applying unit applies force to the rod-shaped part, the seat body can limit the rod-shaped part along the first direction, thereby preventing the rod-shaped part from being deformed along the first direction during the application of force, thereby improving assembly accuracy.

[0020] That is to say, in the embodiment of the present disclosure, force is applied to the rod-shaped part to facilitate the installation of the interference piece, thereby achieving an interference fit between the rod-shaped part and the sheet-shaped part, which can effectively improve the assembly accuracy.

[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of stacked components in the embodiment of the present disclosure, combined with Figure 1 The stacked components include a plurality of sheet components 100 and a rod-shaped component 200 , and the plurality of sheet components 100 are sleeved outside the rod-shaped component 200 .

[0038] Figure 2 for Figure 1 A left view of one of the sheet parts 100, combined with Figure 2 The sheet component 100 may be a thin sheet structure having a rectangular hole 101 therein. Correspondingly, the rod-shaped component 200 is a rod having a rectangular cross section. The rod-shaped component passes through the rectangular hole 101 of the sheet component 100.

[0039] Figure 3 for Figure 1 Cross-sectional view along MM direction, combined with Figure 3 When the sheet component 100 is assembled outside the rod-shaped component 200 , an interference fit between the sheet component 100 and the rod-shaped component 200 is achieved by inserting an interference piece 102 into the rectangular hole 101 of the sheet component 100 .

[0040] Figure 4 A schematic diagram of the structure of an assembly device for stacked components provided in an embodiment of the present disclosure, combined with Figure 4 The assembly device is used to insert an interference fit between a sheet-like component 100 and a rod-like component 200. The assembly device includes a base 1 and an extrusion assembly 2. The base 1 has an accommodating cavity 10 for accommodating the rod-like component. Along a first direction, the inner walls of the accommodating cavity 10 on opposite sides respectively form a clearance fit with the rod-like component.

[0041] The extrusion assembly 2 includes a tightening unit 21 and a force-applying unit 22. The tightening unit 21 and the force-applying unit 22 are located on opposite sides of the rod-shaped part in the second direction. The second direction is perpendicular to the first direction, and the second direction and the first direction are both perpendicular to the length direction of the rod-shaped part. The tightening unit 21 is used to resist the rod-shaped part, and the force-applying unit 22 is used to apply a force along the second direction to the rod-shaped part to increase the gap between the sheet part and the rod-shaped part in the second direction for inserting the interference piece.

[0042] When the sheet-like part 100 is assembled on the rod-like part 200 by the assembly device provided in the embodiment of the present disclosure, since the assembly device includes a base body 1 and the interior of the base body 1 has a receiving cavity 10, the rod-like part 200 can be placed in the receiving cavity 10 of the assembly device first, and then the pre-assembled sheet-like part 100 can be put on the outer cover of the rod-like part 200.

[0043] Because the assembly device further includes a pressing assembly 2, which includes a force-applying unit 22 and a tightening unit 21, the force-applying unit 22 can apply a force along the second direction to the rod-shaped component 200, thereby increasing the gap between the sheet component 100 and the rod-shaped component 200 in the second direction for inserting the interference piece. This increased gap facilitates the insertion of the interference piece 102 between the rod-shaped component 200 and the sheet component 102. The interference piece 102 creates an interference fit between the sheet component 100 and the rod-shaped component 200, thus avoiding the deformation that occurs when the sheet component 100 is pressed into place outside the rod-shaped component 200 as in the related art.

[0044] Furthermore, since the two opposite side walls of the rod-shaped part 200 in the first direction respectively cooperate with the clearance of the base body 1, when the force-applying unit 22 applies force to the rod-shaped part 200, the base body 1 can limit the rod-shaped part 200 along the first direction, thereby preventing the rod-shaped part 200 from being deformed along the first direction during the application of force, thereby improving assembly accuracy.

[0045] That is, in the embodiment of the present disclosure, force is applied to the rod-shaped component 200 to facilitate the insertion of the interference piece 102 , thereby achieving an interference fit between the rod-shaped component 200 and the sheet-shaped component 100 , which can effectively improve assembly accuracy.

[0046] Continue to see Figure 4 Optionally, the force-applying unit 22 includes a first pressing head 221 and a power component 222. The first pressing head 221 and the power component 222 are both partially located in the accommodating chamber 10, and along the second direction, one end of the power component 222 abuts against the first pressing head 221, and the other end of the power component 222 is connected to the base 1. The power component 222 is used to apply a force along the second direction to the first pressing head 221. The side of the first pressing head 221 away from the power component 222 faces the rod-shaped part, and the first pressing head 221 is in sliding engagement with the base 1.

[0047] In the embodiment of the present disclosure, the first direction mentioned above is Figure 4 The up and down direction in can also be the vertical direction. The second direction is Figure 4 The left and right directions in are also the horizontal directions.

[0048] In the above implementation, the power component 222 is used to apply a load to the first pressing head 221, and the first pressing head 221 is used to load the force on the side wall of the rod-shaped part so that the rod-shaped part can be deformed quickly, thereby increasing the gap between the rod-shaped part and the sheet-shaped part to facilitate the installation of the interference fit piece.

[0049] Exemplarily, the power component 222 is an ultra-thin jack. For example, the power component 222 used in the embodiment of the present disclosure is an FPY-20 ultra-thin jack. The power component 222 is connected to an electric hydraulic pump via an oil pipe. The loading pressure of the power component 222 is monitored by using a pressure gauge on the hydraulic pump.

[0050] Figure 5 for Figure 4 The structural diagram of the first pressure head, combined with Figure 5 Optionally, the first pressing head 221 includes a pressing block 2211 and two limiting plates 2212 . The pressing block 2211 is located in the accommodating cavity 10 and abuts against the power component 222 .

[0051] Two limiting plates 2212 are spaced apart along the third direction on opposite sides of the compression block 2211 and are located outside the base 1. Both limiting plates 2212 are connected to the compression block 2211, and along the first direction, both ends of each limiting plate 2212 protrude beyond the compression block 2211. A sliding groove 2210 for accommodating the base 1 is formed between the two limiting plates 2212 and the compression block 2211. The sliding groove 2210 extends in the second direction. The third direction is perpendicular to both the first and second directions.

[0052] In the above implementation, the two limiting plates 2212 can be aligned with the opposite sides of the pressing block 2211 (i.e. Figure 4 The upper and lower ends of the base 1 form a sliding groove 2210 for accommodating the base 1, so that the first pressing head 221 will not separate from the base 1 when a force is applied to the rod-shaped component. In addition, the sliding groove 2210 can cooperate with the base 1 to ensure that the first pressing head 221 can only slide relative to the base 1 along the second direction under the drive of the power component 222.

[0053] For example, along the third direction, the top and bottom of the pressing block 2211 are each provided with a stepped relief structure 2214. The relief structure 2214 is located on a side wall of the pressing block 2211 away from the power component 222. The relief structure 2214 is used to form notches at the top and bottom of the pressing block 2211, thereby accommodating the base 1 through the notches. This ensures that when the first pressing head 221 applies force to the rod-shaped component, it does not interfere with the inner wall of the base 1.

[0054] Along the third direction, the top and bottom of the pressing block 2211 are provided with sliding surfaces 2215, which are perpendicular to the third direction and are used to slide with the inner wall of the base 1. Along the third direction, both ends of each limit plate 2212 protrude beyond the two sliding surfaces 2215.

[0055] Along the second direction, the pressing block 2211 has a pressing surface 2213 in the middle of a side wall facing the rod-shaped component. This surface is located between two relief structures 2214 and on the side of each relief structure 2214 facing the rod-shaped component. This surface 2213 is configured to contact the rod-shaped component to apply a load thereto.

[0056] In order to reduce the weight of the pressing block 2211, a weight-reducing hole 2216 is provided in the middle of the pressing surface 2213. The weight-reducing hole 2216 divides the pressing surface 2213 into two planes spaced apart along the third direction.

[0057] In other examples, the arrangement of the weight-reducing holes 2216 may also be in other positions. For example, the weight-reducing holes are located on the side of the pressing block 2211 facing the limiting plate 2212 .

[0058] Optionally, the pressing unit 21 includes a second pressing head 211 and a pressing component 212, and the second pressing head 211 and the pressing component 212 are both partially located in the accommodating cavity 10. Along the second direction, opposite ends of the pressing component 212 are in contact with the second pressing head 211 and the base body 1, respectively. The end of the second pressing head 211 away from the pressing component 212 abuts against the rod-shaped part, and the second pressing head 211 and the base body 1 are in sliding engagement.

[0059] In the above implementation, the second pressing head 211 is used to abut against the rod-shaped part to limit the position of one side of the rod-shaped part. The pressing member 212 is used to abut against the base body 1 and the second pressing head 211 respectively to limit the position of the second pressing head 211 so that the second pressing head 211 does not move during loading.

[0060] Optionally, the structure of the second pressing head 211 is symmetrically arranged with respect to the first pressing head 221 , and the symmetry axes of the second pressing head 211 and the first pressing head 221 extend along the first direction.

[0061] In the above implementation, the second pressing head 211 and the first pressing head 221 are set as structural parts with the same structure, which not only simplifies the manufacturing process, but also ensures that the opposite sides of the rod-shaped part will not be deformed due to the different structural parts, thereby improving the accuracy.

[0062] In other examples, the structure of the second pressing head 211 may also differ from that of the first pressing head 221. For example, the second pressing head 211 may be a standard rectangular block. This is sufficient as long as it can abut against and limit the side of the rod-shaped component to prevent the rod-shaped component from moving. This disclosure is not limited to this.

[0063] Exemplarily, the pressing member 212 is a block-shaped structural member. In other examples, the pressing member 212 and the second pressing head 211 can also be an integral structural member. As long as it can be conveniently arranged in the base body 1 and can limit the rod-shaped part, this disclosure does not impose any restrictions on this.

[0064] Figure 6 for Figure 4 Schematic diagram of the three-dimensional structure, combined with Figure 6 Optionally, the base body 1 includes an outer frame 11, an upper limit block 12 and a lower limit block 13, the accommodating cavity 10 is located in the middle of the outer frame 11, the upper limit block 12 and the lower limit block 13 are arranged at intervals along the first direction and are partially located in the accommodating cavity 10, and the upper limit block 12 and the lower limit block 13 are respectively connected to the outer frame 11.

[0065] The side of the upper limiting block 12 facing the lower limiting block 13 and the side of the lower limiting block 13 facing the upper limiting block 12 are respectively used for clearance fit with the opposite sides of the rod-shaped part.

[0066] In the above implementation, the outer frame 11 is used to provide an installation basis for structures such as the tightening unit 21 and the force applying unit 22 , and also provides an installation basis for the upper limit block 12 and the lower limit block 13 .

[0067] The upper limiting block 12 and the lower limiting block 13 are respectively used to limit the upper and lower sides of the rod-shaped part along the first direction, so that when the force is applied by the force applying unit 22, the upper and lower sides of the rod-shaped part in the first direction will not be deformed.

[0068] Figure 7 for Figure 6 Half-section view, combined with Figure 7 Optionally, the upper stopper 12 includes a main body 121 and a protrusion 122. The protrusion 122 is located on the side of the main body 121 facing the lower stopper 13, and the side of the protrusion 122 away from the main body 121 is used for clearance fit of the rod-shaped part. The protrusion 122 is connected to the main body 121, and the main body 121 is connected to the outer frame 11.

[0069] Along the second direction, two opposite side walls of the protrusion 122 and the main body 121 respectively form a locking groove 1220 for accommodating a part of the structure of the pressing unit 21 and the force applying unit 22 .

[0070] In the above implementation, the main body 121 is connected to the outer frame 11 to enable the upper stopper 12 to be installed in the outer frame 11, and the protrusion 122 is used to provide a clearance fit with the rod-shaped component. The slot 1220 is provided to ensure that when the force-applying unit 22 applies a load to the rod-shaped component, the tightening unit 21 or the force-applying unit 22 does not interfere with the upper stopper 12 during movement.

[0071] In this embodiment, the main body 121 and the protrusion 122 are integrally formed structural members. That is, the upper stop block 12 is an integral structural member. This can enhance the overall strength of the upper stop block 12.

[0072] In other examples, the main body 121 and the protrusion 122 can also be connected together by fasteners such as bolts. As long as the structural strength of the upper limit block 12 is not affected, the structural form of the upper limit block 12 can be any, such as an assembled type, an integrated part, etc.

[0073] In this embodiment, in order to achieve the installation between the upper limiting block 12 and the outer frame 11, the main body 121 is an L-block-shaped structural member.

[0074] The main body 121 includes a horizontal plate 1211 and a vertical plate 1212, which are vertically connected to define an L-shaped cavity. The L-shaped cavity is used to clamp the outer frame 11. This L-shaped structure allows the main body 121 to be quickly positioned between the outer frame 11.

[0075] Furthermore, the plane of the horizontal plate 1211 is perpendicular to the first direction, and the plane of the vertical plate 1212 is perpendicular to the second direction. The horizontal plate 1211 and the vertical plate 1212 each have a locking hole. Bolts, etc., are inserted into the locking holes, thereby quickly connecting the main body 121 to the outer frame 11.

[0076] In this embodiment, in order to facilitate processing and ensure that the upper limit block 12 has sufficiently high strength, the upper limit block 12 is also an integrated structural member.

[0077] Optionally, the lower limiting block 13 is symmetrically arranged to the upper limiting block 12 , and the symmetry axis of the upper limiting block 12 and the lower limiting block 13 extends along the second direction.

[0078] In the above implementation, the lower limit block 13 and the upper limit block 12 are set to the same structure, so that the upper and lower sides of the rod-shaped part along the first direction are in the same environment, thereby avoiding deformation of the upper and lower sides of the rod-shaped part due to different structural parts.

[0079] In other examples, the lower stopper 13 may also have a different structure from the upper stopper 12. As long as the upper and lower sides of the rod-shaped component can be limited to prevent deformation, the structures of the lower stopper 13 and the upper stopper 12 may be the same or different, or may be other structures.

[0080] Figure 8 A schematic diagram of the structure of the outer frame provided in the embodiment of the present disclosure, combined with Figure 8 Optionally, the outer frame 11 is a hollow plate-like structure. The hollow portion inside the outer frame 11 forms an accommodating cavity 10. Along the third direction, the interior of the outer frame 11 has two guide surface groups distributed at intervals, each guide surface group includes two guide surfaces 111, and the two guide surfaces 111 in the same group are respectively located on opposite sides of the upper limit block 12. The guide surface 111 is used to slide in contact with the sliding surface 2215 of the first pressing head 221 or the second pressing head 211, so as to reduce the wear between the first pressing head 221 or the second pressing head 211 and the outer frame 11.

[0081] The outer frame 11 is provided with through holes 112 on both sides along the third direction. The through holes 112 are used to reduce the weight of the outer frame 11.

[0082] In addition, in order to facilitate the assembly of other components, connecting holes are provided in the inner wall of the outer frame 11, and bolts are inserted into the connecting holes to assemble the force unit 22, the tightening unit 21, the upper limit block 12 and the lower limit block 13 in the outer frame 11.

[0083] Figure 9 This is a structural diagram of the connection between the assembly device and the sliding assembly in the embodiment of the present disclosure, combined with Figure 9 Optionally, the assembly device further includes a sliding component 3, which is connected to the base body 1, and the sliding component 3 is used to enable the base body 1 to move along a third direction, which is perpendicular to the first direction and the second direction.

[0084] In the above implementation, the sliding assembly 3 is used to enable the base body 1 to move along the length direction of the rod-shaped part. In this way, when a sheet part is assembled on the rod-shaped part, the assembly device can be moved so that the assembly device can squeeze the next part of the rod-shaped part so that the next sheet part can be assembled here.

[0085] Continue to combine Figure 9 Optionally, the sliding assembly 3 includes a guide rail 31 and a slider 32. The guide rail 31 is located on one side of the base body 1, and the length direction of the guide rail 31 is the third direction.

[0086] The slider 32 is sleeved outside the guide rail 31 and slidably matched with the guide rail 31 . The slider 32 is connected to the base body 1 .

[0087] In the above implementation, the slider 32 is connected to the base 1 so as to drive the base 1 to slide on the guide rail 31. The guide rail 31 is used to provide a moving track for the slider 32, ensuring that the slider 32 can only move along a limited direction.

[0088] Exemplarily, the slider 32 has a sliding groove inside, and a limit block is provided on one side of the guide rail 31. The limit block is located in the sliding groove, and the limit block is in sliding contact with the groove wall of the sliding groove.

[0089] Optionally, there are two guide rails 31 and two sliders 32 , and the two guide rails 31 are arranged at intervals along the first direction and are parallel to each other.

[0090] The sliders 32 correspond to the guide rails 31 one by one, and each slider 32 is slidably matched with the corresponding guide rail 31 and is connected to the base body 1 .

[0091] In the above implementation, two sliders 32 and two guide rails 31 are provided to improve the guiding performance of the sliding assembly 3, so that the sliding assembly 3 is more stable and does not shake or tilt when driving the seat body 1 to move.

[0092] In this embodiment, in order to further improve the stability of the rod-shaped component, the rod-shaped component is supported by a plurality of supporting structures 201. The plurality of supporting structures 201 are spaced apart at the bottom of the rod-shaped component along the length direction of the rod-shaped component.

[0093] Illustratively, support structure 201 includes a top support block, a support rod, and a base. The support rod's opposite ends are connected to the base and the top support block, respectively. The top support block has a groove that matches the rod-shaped component and is used to accommodate the rod-shaped component. The base is placed on guide rail 31. The specific structure of support structure 201 can be configured based on the shape of the rod-shaped component. For example, in this embodiment, since the rod-shaped component has a rectangular cross-section, a rectangular groove is provided on the top of support structure 201.

[0094] In other examples, the structure of the supporting structure 201 may be other structures, such as a rectangular block structure.

[0095] The following describes the working process of the assembly device provided by the embodiment of the present disclosure:

[0096] See also Figure 9 When using the assembly device provided in the embodiment of the present disclosure to assemble the sheet component 100 onto the rod-shaped component 200, the various components of the assembly device are first assembled together. The rod-shaped component 200 is then placed in the receiving cavity 10 of the assembly device, and the pre-assembled sheet component 100 is placed over the rod-shaped component 200.

[0097] Then, the force-applying unit 22 is controlled to apply a force in the second direction to the rod-shaped component 200. Simultaneously, after the force-applying unit 22 applies the force to the rod-shaped component, a sidewall of the rod-shaped component 200 deforms in the second direction, thereby increasing the gap between the rod-shaped component 200 and the sheet component 100. When the gap is sufficiently large, an interference fit is installed in the gap between the rod-shaped component 200 and the sheet component 100, achieving an interference fit between the sheet component 100 and the rod-shaped component 200.

[0098] When it is time to assemble the next sheet component 100, the force-applying unit 22 and the tightening unit 21 are returned to their initial positions, and the upper and lower stoppers 12, 13 are removed from the outer frame 11. The sliding assembly 3 is then used to allow the outer frame 11 to pass through the newly installed sheet component 100 and position the outer frame 11 in the next assembly position for the rod-shaped component 200. The upper and lower stoppers 12, 13 are then installed onto the outer frame 11. The force-applying unit 22 is then controlled to apply a force in the second direction to the rod-shaped component 200, causing the rod-shaped component 200 to deform at its next assembly position and allowing the next interference fit to be installed. The above steps are repeated until all sheet components 100 are assembled.

[0099] The above description is merely an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
