Abstract
Description
Technical Field
[0001] The present invention relates to a finishing device, belonging to the technical field of automation equipment. Background Art
[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.
[0003] During the automobile production process, a large number of door hinges need to be installed on the automobile body. The quality of the door hinges has a great impact on the quality of the automobile.
[0004] The door hinge is a key component that secures the body and door together, serving as the door's primary load-bearing component. The door pivots around the hinge axis, opening and closing the door. Generally speaking, a door hinge consists of three parts: the door assembly, the body assembly, and the hinge shaft. Bushings may be installed in the pin holes of the door or body assembly, allowing for pivoting around the hinge shaft. Strict requirements exist for the ease with which the door or body assembly can pivot around the hinge pin. The condition of the bushing's inner hole—namely, its shape, size, and smoothness—affects the hinge shaft's rotation, in turn affecting the torque required to pivot the hinge and, consequently, the hinge's assembly quality.
[0005] Fine shaping of the door hinge bushing's inner bore can overcome various factors that affect torque, ensuring the hinge meets the required torque. The key to achieving fine shaping of the bushing's inner bore in the finishing process is the design of a reliable finishing device, combined with a specialized finishing rod, to achieve the desired functional requirements.
[0006] However, the finishing device in the prior art can usually only be installed with one finishing rod; when the finishing rod is switched, it is time-consuming and labor-intensive, which reduces the production efficiency of the finishing device. Utility Model Content

[0070] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.
[0071] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0072] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.
[0073] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.
[0074] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.
[0075] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.
[0076] The terms used herein are for the purpose of describing specific embodiments and are not intended to be restrictive. As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and / or the values provided that will be recognized by those of ordinary skill in the art.
[0077] Figure 1 It is a structural schematic diagram of a finishing device according to one embodiment of the present disclosure.
[0078] like Figure 1 As shown, the finishing device of the present disclosure may include components such as a frame 100 , a lifting platform 200 , a lifting drive device 300 , a rotating module 400 , and a switching module 500 .
[0079] The frame 100 is formed as a supporting structure for components such as the lifting platform 200, the lifting drive device 300, the rotating module 400, and the switching module 500. That is, the lifting platform 200, the lifting drive device 300, the rotating module 400, and the switching module 500 can be directly or indirectly installed on the frame 100. In a specific embodiment, the frame 100 can be formed by fixing a plurality of plate components to each other.
[0080] Figure 2 It is a structural schematic diagram of a lifting platform and a rotating module of a finishing device according to an embodiment of the present disclosure.
[0081] The lifting platform 200 is slidably disposed on the frame 100 so that the lifting platform 200 can generate a lifting motion relative to the frame 100 .
[0082] Specifically, if Figure 2 As shown, the lifting platform 200 of the present disclosure is formed as a plate-shaped member, and the plate-shaped member is disposed substantially horizontally.
[0083] The lifting platform 200 is fixedly connected to a vertical plate 210. The vertical plate 210 is disposed substantially vertically. In a preferred embodiment, the frame 100 is provided with two substantially vertical guide rails. Accordingly, the vertical plate 210 is provided with a slider slidably disposed on the guide rails. The guide rails thereby guide the lifting and lowering movement of the lifting platform 200, thereby ensuring the vertical movement accuracy of the finishing rod 900 during the finishing process.
[0084] The lifting drive device 300 is provided on the frame 100 and is used to drive the lifting platform 200 to move and enable the lifting platform 200 to generate a lifting motion. Specifically, the lifting platform 200 of the present disclosure may be provided with a connecting block 220, and the lifting drive device 300 may be a lifting cylinder or an electric cylinder, wherein the lifting drive device 300 can be connected to the connecting block 220, so that the lifting cylinder can drive the lifting platform 200 to generate a lifting motion.
[0085] The rotating module 400 is rotatably disposed on the lifting platform 200. Specifically, Figure 2 As shown, the rotating module 400 may include a rotating driving device 410 and a rotating component 420 .
[0086] The rotary drive device 410 can be a motor. In a preferred embodiment, the motor can be a servo motor. The motor can be connected to a reducer, and the output shaft of the reducer can be provided with a coupling, such as an elastic coupling or a cross coupling. Furthermore, the rotary drive device 410 or the reducer can be directly or indirectly fixed to the lifting platform 200. In a specific embodiment, the housing of the reducer can be fixed to the vertical plate 210, thereby maintaining the position of the rotary drive device 410 relative to the lifting platform 200.
[0087] The rotating component 420 can be fixedly connected to the coupling, whereby the rotary drive device 410 can drive the rotating component 420 to rotate, that is, the rotating component 420 can not only generate lifting motion with the lifting platform 200, but also rotate relative to the lifting platform 200.
[0088] In the present disclosure, the rotating component 420 can be set on the lifting platform 200 through a bearing. At this time, the bearing can be a bearing of a model such as Misumi NKXZ25. At this time, the bearing can ensure that the position of the rotating component 420 relative to the lifting platform 200 in its axial direction (i.e., vertical direction) remains unchanged.
[0089] More preferably, the rotary drive device 410 disclosed in the present invention is also used to drive the detection sensing plate 430 to rotate. At this time, a first detection device 440 can be provided on the vertical plate 210. The first detection device 440 can be a matching switch. At least part of the detection sensing plate 430 is located between the matching switches. Moreover, at least one slot is provided on the detection sensing plate 430. When the signal emitted by one of the matching switches passes through the slot, it is received by the other matching switch. That is, the circumferential position of the detection sensing plate 430 can be obtained according to the signal of the matching switch being triggered. Furthermore, the circumferential position of the rotating component 420 can also be known to facilitate the subsequent replacement operation of the finishing rod 900.
[0090] Figure 3 Schematic diagram of the structure of the rotating part of the finishing device according to one embodiment of the present disclosure.
[0091] The upper end of the rotating component 420 can be directly or indirectly connected to the coupling, and the lower end of the rotating component 420 is provided with a first groove 421, which penetrates the rotating component 420 in a radial direction, and the opening of the first groove 421 is downward; thus, when the finishing rod 900 moves in the radial direction of the rotating component 420, that is, when the finishing rod 900 moves in the horizontal direction, it can move into the first groove 421, thereby realizing the connection between the finishing rod 900 and the rotating component 420. At this time, when the rotating component 420 is lifted and / or rotated, it can drive the finishing rod 900 to be lifted and / or rotated together.
[0092] More preferably, both sidewalls of the first groove 421 are recessed inward, forming a recessed portion 422. The inward recess in the present disclosure refers to a recess extending from the sidewalls of the first groove 421 in a radially outward direction relative to the rotating component 420. Thus, the first groove 421 and the recessed portion 422 of the present disclosure collectively form a T-shaped slot at the lower end of the rotating component 420.
[0093] Figure 4 It is a structural schematic diagram of a switching module of a finishing device according to an embodiment of the present disclosure.
[0094] The switching module 500 of the present disclosure can replace the finishing rod 900 connected to the rotating component 420. Specifically, the switching module 500 of the present disclosure can include: a retaining frame 510, a switching drive device, and the finishing rod 900.
[0095] Specifically, the frame 100 is provided with a guide rail arranged radially (i.e., horizontally) relative to the rotating member 420; the retainer 510 is slidably mounted on the guide rail. Furthermore, the retainer 510 of the present disclosure is capable of retaining at least two finishing rods 900.
[0096] The switching drive device is used to drive the retaining frame 510 to move in the radial direction of the rotating part 420. Therefore, in the present disclosure, when the retaining frame 510 moves in the horizontal direction, it can enable at least one of the two finishing rods 900 to cooperate with the rotating part 420 and be driven and rotated by the rotating part 420.
[0097] In other words, the switching module 500 disclosed in the present invention can realize the replacement of the finishing rod 900, thereby improving the production efficiency of the finishing device.
[0098] Refer again Figure 4 In the present disclosure, the finishing rod 900 is rotatably disposed on the holder 510 , and the holder 510 is capable of limiting the position of the finishing rod 900 in the axial direction.
[0099] Figure 5Schematic diagram of the structure of a finishing rod 900 of a finishing device according to an embodiment of the present disclosure.
[0100] like Figure 5 As shown, the finishing rod 900 of the present disclosure is provided with an annular groove 910, which may have a semicircular cross-section. Furthermore, the retainer 510 is provided with elastic balls. When at least a portion of the elastic balls are located within the annular groove 910, the axial position of the finishing rod 900 is maintained. In other words, the finishing rod 900 will not slide downward due to gravity.
[0101] On the other hand, when the finishing rod 900 is driven by the rotating component 420 and moves downward, that is, when the finishing rod 900 is subjected to a downward force, the elastic ball can leave the annular groove 910, thereby the finishing rod 900 can generate a lifting motion.
[0102] In the present disclosure, an outer flange is formed at the upper end of the finishing rod 900, and at least a portion of the outer flange is located in the recess 422; wherein, at least a portion of the circumferential surface of the outer flange is in plane contact with the recess 422, thereby, the rotating component 420 can drive the finishing rod 900 to rotate.
[0103] Generally speaking, the upper end of the finishing rod 900 of the present disclosure is formed into a T-shaped portion, which can be inserted into the T-shaped slot and can also be removed from the T-shaped slot, so that the finishing rod 900 can be easily replaced.
[0104] In the present disclosure, the switching drive device includes: a first drive device 520 and a second drive device 530. The first drive device 520 is fixed to the frame 100; the second drive device 530 is slidably disposed on the guide rail, and the first drive device 520 is used to drive the second drive device 530 to slide along the guide rail; the second drive device 530 is used to drive the retaining frame 510 to slide along the guide rail.
[0105] In a specific embodiment, the first drive device 520 can be a cylinder, and the second drive device 530 can also be a cylinder; since the cylinder only has two states of extension and retraction, and accordingly only has two moving positions, the present application realizes three workstations through two cylinders arranged in series, that is, realizes the replacement of three finishing rods 900.
[0106] Specifically, when the first driving device 520 and the second driving device 530 are both in the retracted state, Figure 4 The rightmost finishing rod 900 is matched with the rotating member 420. When one of the first driving device 520 and the second driving device 530 is in the extended state and the other is in the retracted state, Figure 4The middle finishing rod 900 cooperates with the rotating component 420. When the first driving device 520 and the second driving device 530 are both in the extended state, Figure 4 The leftmost finishing rod 900 cooperates with the rotating component 420 .
[0107] Those skilled in the art will appreciate that the switching drive device disclosed herein can also be implemented using an electric cylinder (i.e., a lead screw structure driven by a motor). However, a switching drive device using two pneumatic cylinders is low-cost and simple to control.
[0108] Figure 6 It is a structural schematic diagram of a detection module of a finishing device according to an embodiment of the present disclosure.
[0109] The finishing device of the present disclosure further includes a detection module 600, which is used to detect whether the rotating component 420 is connected to the finishing rod 900. In other words, the detection module 600 of the present disclosure can detect whether the rotating component 420 is correctly connected to the finishing rod 900.
[0110] like Figure 6 As shown, the detection module 600 disclosed herein may include: a detection cylinder 610 and a detection fixture 620; wherein, the detection cylinder 610 is arranged on the frame 100; the detection fixture 620 is arranged on the detection cylinder 610, and the detection fixture 620 is driven to extend or retract by the detection cylinder 610, wherein the detection fixture 620 includes a receiving groove, and when the detection fixture 620 is driven and extended, the finishing rod 900 can be located in the receiving groove.
[0111] Specifically, the detection fixture 620 disclosed in the present invention can be set directly below the rotating part 420. Thus, when the detection cylinder 610 is extended, if the detection fixture 620 is not blocked, the detection cylinder 610 will be in a fully extended state. At this time, the fully extended state of the detection cylinder 610 can be obtained by the position switch of the detection cylinder 610; combined with other detection devices, it can be determined that the finishing rod 900 is correctly installed.
[0112] In addition, when the detection fixture 620 is blocked by the finishing rod 900 during the extension process, it means that the finishing rod 900 has deviated from the 620 receiving slot of the detection fixture, which correspondingly indicates that the finishing rod 900 is not correctly installed on the rotating part 420; in this state, the position switch of the detection cylinder 610 will not be triggered, and the state of the position switch can assist in determining whether the finishing rod 900 is correctly installed.
[0113] In the present disclosure, when the finishing rod 900 is correctly installed, the upper end of the finishing rod 900 can move into the first groove 421 , and the finishing rod 900 and the rotating component 420 have the same rotation axis.
[0114] Refer again Figure 4 In the present disclosure, the switching module 500 further includes a second detection device 540 , which can be a beam switch, and the second detection device 540 can detect whether the finishing rod 900 can move normally during the finishing process.
[0115] In addition, the switching module 500 also includes a third detection device 550, which can be a reflection switch. The reflection switch is installed below the rotating part 420, and the signal emitted by the reflection switch can intersect with the rotation axis of the rotating part 420. Therefore, when the finishing rod 900 is correctly installed on the rotating part 420, the signal emitted by the reflection switch can be reflected by the finishing rod 900 and contacted by the reflection switch. Therefore, by triggering the reflection switch, it can be determined whether the finishing rod 900 is correctly installed on the rotating part 420.
[0116] Figure 7 2 is a schematic structural diagram of a pre-pressing module 700 of a finishing device according to an embodiment of the present disclosure.
[0117] like Figure 7 As shown, the finishing device of the present disclosure further includes a pre-pressing die set 700 , which is used to press the workpiece on the tooling.
[0118] More specifically, the pre-pressing module 700 of the present disclosure includes a pre-pressing block 710 , a pre-pressing driving device 720 and a clamping driving module 730 .
[0119] The rack 100 of the present disclosure may be provided with a base 740 that is substantially vertically disposed. The base 740 may be provided with a guide rail that is vertically disposed.
[0120] The pre-pressing block 710 is slidably disposed on the frame 100. Specifically, a slider is disposed on the pre-pressing block 710, and the slider is slidably disposed on the guide rail, thereby enabling the pre-pressing block 710 of the present disclosure to be driven to generate a lifting motion.
[0121] The pre-stressing drive device 720 is disposed on the base 740 (ie, indirectly disposed on the frame 100 through the base 740 ), and is used to drive the pre-stressing block 710 to move up and down; in the present disclosure, the pre-stressing drive device 720 may be a cylinder.
[0122] The clamping drive module 730 is disposed on the frame 100 and is capable of approaching or moving away from the pre-pressing block 710 in a direction perpendicular or substantially perpendicular to the movement direction of the pre-pressing block 710. When the clamping drive module 730 approaches the pre-pressing block 710, the pre-pressing block 710 is clamped by the clamping drive module 730. In a preferred embodiment, two clamping drive modules 730 are provided, thereby enabling the pre-pressing block 710 to be clamped in two directions, thereby ensuring that the pre-pressing block 710 can be stably held by the clamping drive modules 730.
[0123] During the conventional hinge assembly process, a bushing is first installed into the inner hole of the door (or body). The bushing is then expanded, flanging, and finished, and the hinge shaft is inserted into the bushing hole. The hinge shaft is then assembled with the body (or door) and finally tested for various parameters. The hinge shaft rotates within the bushing, and strict requirements for the bushing's finishing dimensions are required to ensure torque parameters. Because the bushing itself is made of a soft material, installing it in the inner hole of the door (or body) requires not only to account for the bushing's own tolerances but also to accommodate dimensional tolerances within the door (or body) hole, which increases the complexity of the finishing process.
[0124] In other words, because finishing is a relatively complex process, it is difficult to improve production efficiency on its own, which requires the development of new processes to achieve this. Selecting the appropriate finishing rod according to different product requirements and being able to switch to the required finishing rod with one click can save a lot of time and cost.
[0125] Based on this, the disclosed finishing device is a bushing inner bore finishing device used in automated door hinge assembly lines, specifically for assembling automotive door hinges. This device utilizes a dual-stage drive with a changeable finishing rod, automatically switching finishing rods to meet specific finishing requirements. The finishing device simultaneously presses downward and rotates, causing the finishing rod to penetrate the bushing inner bore. The rod then continues to rotate upward, disengaging the bushing inner bore. Rotation ceases, and the finishing device ascends to its original position, completing the finishing process.
[0126] Specifically, when the tooling 800 drives the product to the finishing station (or the product is manually placed and fixed in the tooling under the finishing station), the pre-pressing module 700 descends, driving the pre-pressing block 710 to press the product, and the clamping drive modules 730 on both sides clamp the pre-pressing block 710 to ensure that the product remains in place; the lifting drive device 300 is activated, driving the rotating module 400 to descend.
[0127] The rotary drive device 410 starts to rotate, and drives the rotating component 420 and the finishing rod 900 to rotate together. At this time, the finishing rod 900 will slowly descend while rotating along with the rotating module 400.
[0128] The rotary module 400 continues to rotate and descend, passing through the inner hole of the product bushing. After both finishing sections of the finishing rod 900 enter the bushing, the lifting drive 300 switches to reverse motion, driving the rotary module 400 upward. When both finishing sections of the finishing rod 900 are released from the bushing, the rotary drive 410 stops rotating. The lifting drive 300 continues to rise and returns to its original position. The clamping drive modules 730 on both sides of the pre-pressing module 700 retract, releasing the pre-pressing block 710. The pre-pressing drive extends, driving the pre-pressing module 700 upward, and the pre-pressing block 710 is separated from the product. The tooling 800 drives the product to be removed (or manually removed), and the finishing process is complete. Wait for the next group of products to arrive, and repeat the above steps to continue the next round of finishing.
[0129] When there are different requirements for the inner hole finishing size of the product bushing, the finishing rod can be automatically changed by switching modules.
[0130] Specifically, when the lifting drive device 300 and the rotating drive device 410 are both retracted and in the initial position, a finishing rod 900 is in the working position (that is, the finishing rod 900 is connected to the rotating part 420); the third detection device 550 can detect the presence of the finishing rod 900. At this time, the detection cylinder 610 of the detection module 600 is pushed out, and the detection fixture 620 clamps the finishing rod 900. The detection module detects whether the finishing rod 900 is installed in place during the finishing process.
[0131] If a different finishing rod 900 is needed, the detection module retracts and the detection fixture disengages from the finishing rod 900. The first and / or second drive devices are activated, driving the retaining frame 510 to move. The finishing rod 900 connected to the rotating component 420 is disengaged from the rotating component 420, and the new finishing rod 900 enters the T-slot of the rotating component 420. At this point, the new finishing rod 900 is in the working position. The detection module detects the presence of the finishing rod; the detection module is pushed out, and the detection fixture clamps the finishing rod 900, completing the replacement of the finishing rod.
