Description

Technical Field

[0001] This utility model relates to the field of automated door handle assembly technology, specifically to an integrated door handle assembly device. Background Technology

[0002] Door handles are an indispensable component of door panels, designed to facilitate manual operation of the door opening and closing. Current handle designs exhibit diverse forms, particularly in the unique designs of the handle and panel, while core components such as snap rings, corner limiters, torsion springs, and washers tend towards standardization. (See attached image) Figure 1 As shown, the door handle includes a handle a, a washer b, a panel c, a torsion spring d, a corner limiting piece e, a washer f, and a retaining spring g arranged in sequence. The purpose of assembling the door handle is to integrate the torsion spring d, the corner limiting piece e, the washer f, and the retaining spring g onto the handle a and the panel c. The washer b connects the handle a and the panel c.

[0003] Automated assembly mechanisms are increasingly being introduced into the assembly of door handles to improve efficiency. For example, Chinese patents CN118789271A and CN105537931A disclose automated door handle assembly equipment. This equipment uses tooling or fixtures to sequentially pass through an assembly mechanism, installing each component onto the tooling or fixture to achieve door handle assembly. While this type of automated door handle assembly equipment can improve efficiency, the need for a separate mechanism for each component to be installed onto the tooling or fixture results in high unit cost and a large footprint.

[0004] In view of this, there is an urgent need to design an integrated door handle assembly equipment to solve the defects of existing automatic door handle assembly equipment. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides an integrated door handle assembly device, comprising a machine frame, a tooling positioning plate on the table surface of the machine frame and a torsion spring tensioning assembly located beside the tooling positioning plate, a pull-down assembly and a tooling positioning seat inside the machine frame, the tooling positioning seat being located below the tooling positioning plate, a mandrel and a torsion spring positioning component on the tooling positioning seat, a handle positioning component fixedly connected to the tooling positioning seat at the center of the mandrel, the handle positioning component being linked to the pull-down assembly, and the torsion spring positioning component being retractably connected to the tooling positioning seat via an elastic reset component, the torsion spring positioning component, the mandrel and the handle positioning component all extending to the outside of the tooling positioning plate.

When the mandrel petal outward moving assembly drives the mandrel petal to move in the opposite direction to the center of the mandrel hole, the mandrel petals separate from each other and a mandrel limiting groove is formed between adjacent mandrel positioning parts.

[0007] This utility model is further configured as follows: the mandrel lobe outward movement assembly includes a mandrel lobe outward movement force source, a synchronous top plate driven by the mandrel lobe outward movement force source, and an outward movement trigger connected to the synchronous top plate. A connecting rod pin is provided on the tooling positioning seat, and an outward movement connecting rod is movably connected to the connecting rod pin. The outward movement connecting rod includes a linkage end and a trigger end. A mandrel linkage groove is opened on the mandrel limiting part, and the linkage end is connected in the mandrel linkage groove. The outward movement trigger is driven by the mandrel lobe outward movement force source to form a linkage cooperation with the trigger end.

[0008] The present invention is further configured as follows: the external triggering element includes a triggering platform and a triggering roller rotatably connected to the triggering platform; a triggering slope is formed on the side of the triggering end near the triggering roller; and the triggering roller is positioned directly opposite the triggering slope.

The tooling positioning seat and the spindle flap outward movement assembly are both located on the pull-down frame. The pull-down frame is provided with an outward movement guide post, and a synchronous top plate is connected to the outward movement guide post. A pull-down ejector pin is connected to the pull-down power source. The end of the pull-down ejector pin near the handle positioning component is provided with a nail head. A positioning through hole is opened in the center of the handle positioning component. Several notches are opened on the outer side of the end of the handle positioning component away from the tooling positioning seat. The pull-down ejector pin is connected in the positioning through hole. The size of the nail head is larger than the diameter of the positioning through hole. A pull-down return spring for resetting the pull-down frame is provided on the pull-down guide post. A pull-down limiting post for limiting the movement stroke of the pull-down frame is provided on the pull-down fixing plate.

[0010] The present invention is further configured such that the torsion spring positioning component includes a torsion spring positioning part and a torsion spring limiting part. The tooling positioning seat is provided with a positioning component movable groove. One end of the elastic reset component abuts against the bottom of the positioning component movable groove, and the other end of the elastic reset component abuts against the torsion spring limiting part.

A tensioning stroke block is connected on the tensioning slide rail, and the tensioning stroke block is movably connected in the tensioning stroke groove.

[0013] The present invention is further configured such that the torsion spring positioning part and the upper tension actuating part are on the same working plane. When the upper tension actuating part acts on the upper tension guide slope, the torsion spring positioning part moves toward the elastic reset part and compresses the elastic reset part, so that the outer edge of the torsion spring passes over the torsion spring positioning part. When the upper tension actuating part moves away from the upper tension guide slope, the torsion spring positioning part resets to block the outer edge of the torsion spring.

[0014] The present invention is further provided with a torsion spring pressing assembly on the side of the tooling positioning plate. The torsion spring pressing assembly includes a torsion spring pressing power source and a torsion spring pressure plate driven by the torsion spring pressing power source.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] The working principle of this integrated door handle assembly equipment is as follows: The retaining ring, washer, corner limiting plate, torsion spring, panel, and gasket are sequentially fitted onto the spindle. The corner limiting plate is engaged with the spindle at a specified angle. After the torsion spring is fitted onto the spindle, the torsion spring tensioning assembly tensions the torsion spring, positioning both ends of the torsion spring on the spindle and the torsion spring positioning component, respectively. The handle is then connected to the handle positioning component. A pull-down assembly pulls down the handle positioning component and the tooling positioning seat, causing the handle to pass through the panel and assemble the retaining ring, washer, corner limiting plate, torsion spring, panel, and gasket onto the handle's pivot end, thus assembling the door handle. After assembly, the door handle is removed, and the pull-down assembly is reset.

[0017] This utility model of an integrated door handle assembly equipment integrates the mandrel, torsion spring positioning component, and handle positioning component onto the same tooling positioning seat, and sets up a pull-down assembly for the final pressing action of the door handle. This integrates the original multi-step assembly process into the same tooling positioning seat, significantly reducing equipment complexity and manufacturing costs. At the same time, the vertical layout of the internal pull-down assembly and the tooling positioning seat significantly reduces the size of the equipment and improves the utilization rate of workshop space. This equipment can sequentially complete the steps of component loading and positioning, torsion spring tightening, and product pressing on the same tooling positioning plate, enabling the equipment to have the ability to perform continuous operation of multiple processes at a single station.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Combined with appendix Figure 2 To be continued Figure 17 As shown, the present invention provides an integrated door handle assembly device, comprising a machine frame 1. The machine frame 1 has a tooling positioning plate 11 and a torsion spring tensioning assembly 2 located beside the tooling positioning plate 11. The machine frame 11 has a pull-down assembly 3 and a tooling positioning seat 4 inside. The tooling positioning seat 4 is located below the tooling positioning plate 11. The tooling positioning seat 4 has a spindle 5 and a torsion spring positioning component 6. The center of the spindle 5 has a handle positioning component 7 fixedly connected to the tooling positioning seat 4. The handle positioning component 7 is linked to the pull-down assembly 3. The torsion spring positioning component 6 is retractably connected to the tooling positioning seat 4 through an elastic reset component 61. The torsion spring positioning component 6, the spindle 5, and the handle positioning component 7 all extend to the outside of the tooling positioning plate 11.

[0037] In this embodiment, the spindle 5 is used for coaxial mounting of various components of the door handle, the torsion spring positioning component 6 is used for positioning when the torsion spring is tensioned, the handle positioning component 7 is used for positioning when the handle is installed, the torsion spring tensioning component 2 is used to tension the torsion spring mounted on the spindle 5, and the pull-down component 3 is used to press and assemble the door handle components on the tooling positioning plate 11.

[0038] In this embodiment, as shown in the appendix Figure 1 As shown, the handle a has a rotating shaft end a1, and the rotating shaft end a1 has a retaining spring positioning groove a2 for positioning the retaining spring g; the washer b is annular; the panel c has a through hole c1; the torsion spring d includes an outer edge end d1 and an inner edge end d2, the outer edge end d1 is connected to the torsion spring positioning part 6 after being wound, and the inner edge end d2 is connected to the spindle part 5 during assembly; the corner limiting piece e includes a stop part e1 and a limiting end e2, the limiting end e2 is connected to the spindle part 5 during assembly; the washer f is annular; the retaining spring g has an annular structure with an opening.

[0039] In this embodiment, as an example, the loading sequence of the door handle components on the integrated door handle assembly equipment is as follows: snap ring g, washer f, corner limiting piece e, torsion spring d, panel c, washer b, and handle a. For other different door handles, the loading sequence may be different, but the integrated door handle assembly equipment of this embodiment can still be used to assemble the door handle.

[0040] In this embodiment, the working principle of the integrated door handle assembly equipment is as follows: the retaining spring g, the washer f, the corner limiting piece e, the torsion spring d, the panel c, and the washer b are sequentially fitted onto the spindle 5, wherein the corner limiting piece e is engaged with the spindle 5 at a specified angle. After the torsion spring d is fitted onto the spindle 5, the torsion spring tensioning assembly 2 tensions the torsion spring d, positioning both ends of the torsion spring d on the spindle 5 and the torsion spring positioning piece 6, respectively. Then, the handle a is connected to the handle positioning piece 7. The pull-down assembly 3 drives the handle positioning piece 7 and the tooling positioning seat 4 to pull down, thereby driving the handle a through the panel c and assembling the retaining spring g, the washer f, the corner limiting piece e, the torsion spring d, the panel c, and the washer b onto the rotating shaft end a1 of the handle a, thereby realizing the assembly of the door handle. After the assembly is completed, the door handle is removed and the pull-down assembly is reset.

[0041] In this embodiment, the tooling positioning seat 4 has a mandrel hole 41, and the mandrel component 5 includes a plurality of mandrel petals 51 arranged in a ring around the mandrel hole 41. Each mandrel petal 51 includes a mandrel positioning part 511 and a mandrel limiting part 512. The tooling positioning seat 4 has an outward movement channel 42, and a mandrel petal reset member 52 is provided in the outward movement channel 42. The mandrel limiting part 512 is located in the outward movement channel 42, and the mandrel petal reset member 52 abuts against the mandrel limiting part 512. The mandrel lobe 51 is moved toward the center of the mandrel hole 41. The mandrel positioning part 511 extends to the outside through the mandrel hole 41. The tooling positioning seat 4 is provided with a mandrel lobe outward moving component 8 on the side, which drives the mandrel lobe 51 to move in the opposite direction to the center of the mandrel hole 41. When the mandrel lobe outward moving component 8 drives the mandrel lobe 51 to move in the opposite direction to the center of the mandrel hole 41, the mandrel lobe 51 separates from each other and a mandrel limiting groove 53 is formed between adjacent mandrel positioning parts 511.

[0042] In this embodiment, the mandrel 5 is composed of a plurality of mandrel petals 51. When the mandrel petal outward displacement component 8 does not drive the mandrel petals 51, the mandrel petals 51 converge around the mandrel hole 41, which is the converged state of the mandrel 5. When the mandrel petal outward displacement component 8 drives the mandrel petals 51, the mandrel petals 51 move in the opposite direction to the center of the mandrel hole 41, which is the expanded state of the mandrel 5. A mandrel limiting groove 53 is formed between the mandrel positioning parts 511.

[0043] In this embodiment, the retaining spring g is sleeved on the mandrel 5 in a gathered state. After the retaining spring g is sleeved in place, the mandrel 5 is expanded by the mandrel flap outward displacement assembly 8. When the corner limiting piece e is sleeved on the mandrel 5, its limiting end e2 is engaged in the mandrel limiting groove 53. When the torsion spring d is sleeved on the mandrel 5, its inner edge end d2 is engaged in the mandrel limiting groove 53.

[0044] In this embodiment, the mandrel lobe outward movement assembly 8 includes a mandrel lobe outward movement force source 81, a synchronous top plate 82 driven by the mandrel lobe outward movement force source 81, and an outward movement trigger 83 connected to the synchronous top plate 82. A connecting rod pin 43 is provided on the tooling positioning seat 4, and an outward movement connecting rod 44 is movably connected to the connecting rod pin 43. The outward movement connecting rod 44 includes a linkage end 441 and a trigger end 442. A mandrel linkage groove 513 is provided on the mandrel limiting part 512, and the linkage end 441 is connected in the mandrel linkage groove 513. The outward movement trigger 83 is driven by the mandrel lobe outward movement force source 81 and forms a linkage cooperation with the trigger end 442.

[0045] In this embodiment, the external moving force source 81 of the mandrel lobe drives the synchronous top plate 82 to rise, so that each external moving trigger 83 acts synchronously on the trigger end 442 of the external moving link 44, changing the mandrel 5 from a gathered state to an expanded state.

[0046] In this embodiment, the outward-moving trigger 83 includes a trigger platform 831 and a trigger roller 832 rotatably connected to the trigger platform 831. The trigger end 442 forms a trigger slope 443 on the side near the trigger roller 832, and the trigger roller 832 is positioned directly opposite the trigger slope 443. This structure makes the triggering action of the outward-moving trigger 83 on the outward-moving connecting rod 44 more sensitive and smooth.

[0047] In this embodiment, the pull-down assembly 3 includes a pull-down fixing plate 31, a pull-down guide post 32 connected to the pull-down fixing plate 31, a pull-down frame 33 movably connected to the pull-down guide post 32, and a pull-down power source 34 fixed to the pull-down fixing plate 31. The tooling positioning seat 4 and the mandrel flap outward displacement assembly 8 are both located on the pull-down frame 33. The pull-down frame 33 is provided with an outward displacement guide post 84. The synchronous top plate 82 is connected to the outward displacement guide post 84. A pull-down ejector pin 35 is connected to the pull-down power source 34. A nail head 351 is provided at one end near the handle positioning component 7. A positioning through hole 71 is provided in the center of the handle positioning component 7. Several notches 72 are provided on the outer side of the end of the handle positioning component 7 away from the tooling positioning seat 4. The pull-down pin 35 is connected in the positioning through hole 71. The size of the nail head 351 is larger than the diameter of the positioning through hole 71. A pull-down return spring 36 for resetting the pull-down frame 33 is provided on the pull-down guide post 32. A pull-down limit post 37 for limiting the movement stroke of the pull-down frame 33 is provided on the pull-down fixing plate 31.

[0048] In this embodiment, when the pull-down power source 34 is activated, it drives the pull-down pin 35 to move downward. The pin head 351 expands the end of the handle positioning member 7, so that the handle positioning member 7 drags the rotating shaft end a1 of the handle a downward, thereby putting all the components on the spindle member 5 onto the handle a.

[0049] In this embodiment, the torsion spring positioning member 6 includes a torsion spring positioning part 62 and a torsion spring limiting part 63. The tooling positioning seat 4 has a positioning member movable groove 45. One end of the elastic reset member 61 abuts against the bottom of the positioning member movable groove 45, and the other end of the elastic reset member 61 abuts against the torsion spring limiting part 63. The torsion spring limiting part 63 has a positioning member limiting hole 64. A positioning member limiting pin 46 is transversely inserted in the positioning member movable groove 45, and the positioning member limiting pin 46 is connected in the positioning member limiting hole 64.

[0050] In this embodiment, the tooling positioning plate 11 is provided with a positioning member relief groove 12 and a spindle member relief groove 13. The torsion spring positioning part 62 is movably connected in the positioning member relief groove 12. The torsion spring positioning part 62 is provided with a tension guide slope 65 on the side near the torsion spring tensioning assembly 2. The spindle member 5 and the handle positioning part 7 are movably connected in the spindle member relief groove 13. The tooling positioning plate 11 is the bearing surface on which the parts are sleeved on the spindle member 5.

[0051] In this embodiment, the torsion spring tensioning assembly 2 includes a tensioning power source 21, a tensioning movable plate 22 driven by the tensioning power source 21, a tensioning slider 23 fixed on the tensioning movable plate 22, a tensioning slide rail 24 movably connected to the tensioning slider 23, and a tensioning actuator 25 connected to the end of the tensioning slide rail 24. A tensioning base plate 26 is provided on the side of the tensioning movable plate 22. A tensioning stroke groove 261 is provided on the tensioning base plate 26. A tensioning stroke block 27 is connected to the tensioning slide rail 24. The tensioning stroke block 27 is movably connected in the tensioning stroke groove 261.

[0052] In this embodiment, the trajectory of the upper winding stroke groove 261 on the upper winding base plate 26 is not limited, and is designed according to the structural dimensions of different torsion springs and the relative distance between the upper winding actuating member 25 and the spindle member 3. (See attached...) Figure 14 As shown, when the upper tension power source 21 drives the upper tension movable plate 22 to move along the X direction, the upper tension stroke block 27 moves in the upper tension stroke groove 261 in the S direction, causing the upper tension slide rail 24 to move on the upper tension slider 23, thereby controlling the movement of the upper tension actuating member 25 in the Y direction (along the direction of the upper tension slide rail 24). At this time, the movement trajectory of the upper tension actuating member 25 is the superposition of the displacement in the X direction and the displacement in the Y direction, so as to form the upper tension action trajectory of the torsion spring d.

[0053] In this embodiment, the torsion spring positioning part 62 and the upper tension actuating member 25 are on the same working plane. When the upper tension actuating member 25 acts on the upper tension guide slope 65, the torsion spring positioning part 62 moves toward the elastic reset member 61 and compresses the elastic reset member 61, so that the outer edge end d1 of the torsion spring d passes over the torsion spring positioning part 511. When the upper tension actuating member 25 moves away from the upper tension guide slope 65, the torsion spring positioning part 62 resets to block the outer edge end d1 of the torsion spring d.

[0054] In this embodiment, a torsion spring pressing assembly 9 is also provided on the side of the tooling positioning plate 11. The torsion spring pressing assembly 9 includes a torsion spring pressing power source 91 and a torsion spring pressure plate 92 driven by the torsion spring pressing power source 91. The torsion spring pressure plate 92 is provided with a torsion spring pressing part 93 for pressing the torsion spring d. The tooling positioning plate 11 is provided with a panel positioning pin 14.

[0055] In this embodiment, before the torsion spring d is tensioned, the torsion spring pressing power source 91 drives the torsion spring pressure plate 92 to move toward the spindle 5, so that the torsion spring pressure plate 92 presses against the upper end face of the torsion spring d, thus preventing the torsion spring d from shifting during the tensioning process of the torsion spring tensioning assembly 2.

[0056] In this embodiment, the panel positioning pin 14 can be selected according to the different panel structures of the door handle. (See attached...) Figure 16 The panel positioning pin 14 on the tooling positioning plate 11 is suitable for small panel door handles; as shown in the attached... Figure 17 The panel positioning pin 14 on the tooling positioning plate 11 is suitable for long panel door handles.

[0057] This utility model of an integrated door handle assembly equipment integrates the spindle 5, torsion spring positioning 6, and handle positioning 7 onto the same tooling positioning seat 4, and sets up a pull-down assembly 3 to perform the final pressing action of the door handle. This integrates the original multi-step assembly process into the same tooling positioning seat 4, significantly reducing equipment complexity and manufacturing costs. At the same time, the vertical layout of the internal pull-down assembly 3 and the tooling positioning seat 4 significantly reduces the size of the equipment and improves the utilization rate of workshop space. This equipment can sequentially complete the steps of component loading and positioning, torsion spring tightening, and product pressing on the same tooling positioning plate 11, enabling the equipment to have the ability to perform continuous operation of multiple processes at a single station.
