These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] The present application embodiment provides a clamp device 00, please refer to Figure 1 , Figure 1 It is a three-dimensional structural schematic diagram of a clamp device provided in an embodiment of the present application. The clamp device 00 includes: a mounting frame 10, a driving assembly 20, a rotating bracket 30 and a plurality of clamp assemblies 40.

[0040] The mounting frame 10 is used to mount other components in the clamp device 00 to improve the overall structural stability of the clamp device 00. For example, the mounting frame 10 can be used to mount a driving component 20, a rotating bracket 30, and a plurality of clamp components 40.

[0041] The driving assembly 20 is mounted on the mounting frame 10. Here, the driving assembly 20 is fixed on the mounting frame 10 to ensure the structural stability of the driving assembly 20 during use. The driving assembly 20 can be used to drive the rotating bracket 30 to rotate.

[0042] The rotating bracket 30 is rotatably connected to the mounting bracket 10 and connected to the driving assembly 20. The rotating bracket 30 has a plurality of mounting surfaces M in the circumferential direction. Here, the plurality of mounting surfaces M of the rotating bracket 30 are used to mount a plurality of clamp assemblies 40, so that when the rotating bracket 30 rotates in the circumferential direction, the clamp assemblies 40 can be driven to rotate. Exemplarily, the rotating bracket 30 can be a multi-faceted rotating hub, and rolling bearings are installed at both ends of the multi-faceted rotating hub to realize the rotation function of the rotating bracket 30.

[0043] It should be noted that Figure 1The rotating bracket 30 with four mounting surfaces M is taken as an example, but the embodiment of the present application is not limited to this. The embodiment of the present application can set the number of mounting surfaces M of the rotating bracket 30 according to the needs. For example, the rotating bracket 30 can also have six mounting surfaces M or eight mounting surfaces M.

[0044] Multiple fixture assemblies 40 correspond to multiple mounting surfaces M, and the fixture assemblies 40 are installed on the corresponding mounting surfaces M. Different fixture assemblies 40 are of different types, and one type of fixture assembly 40 is used to clamp one type of parts. Here, the fixture assembly 40 can fix and position the clamped parts to facilitate the implementation of subsequent processes, such as welding and assembly processes. The fixture device 00 integrates multiple fixture assemblies 40, which reduces the fixture cost in the mixed-line production process of multiple models and reduces the footprint of the fixture.

[0045] In the embodiment of the present application, the types of parts clamped by the various types of clamp assemblies 40 include various situations. Exemplarily, the parts clamped by the various types of clamp assemblies 40 can be parts of different models, for example, multiple clamp assemblies 40 are used to clamp engine hoods of different models, so that the clamp device 00 can be applied to the mixed production of multiple models, and the effect of quickly switching the clamp assembly 40 can be achieved by rotating the rotating bracket 30. However, the present application is not limited to this. For example, the parts clamped by the various types of clamp assemblies 40 can also be different parts such as engine hoods and car doors.

[0046] It should be noted that, in order to clearly illustrate other structures in the fixture device 00, Figure 1 Only one clamp assembly 40 is shown as an example, but the present embodiment is not limited to this. The other mounting surfaces M of the rotating bracket 30 can also be mounted with the clamp assembly 40, and the arrangement of other clamp assemblies 40 can refer to Figure 1 The clamp assembly 40 is shown. For example, Figure 1 The four mounting surfaces M of the rotating bracket 30 shown can respectively mount the clamp assembly 40 of the first vehicle model, the clamp assembly 40 of the second vehicle model, the clamp assembly 40 of the third vehicle model, and the clamp assembly 40 of the fourth vehicle model.

[0047] There are many cases where the multiple clamp assemblies 40 correspond to the multiple mounting surfaces M. In one case, the multiple clamp assemblies 40 correspond to the multiple mounting surfaces M one by one, and the multiple mounting surfaces M of the rotating bracket 30 are all installed with the clamp assemblies 40. In another case, a part of the multiple mounting surfaces M corresponds to the multiple clamp assemblies 40 one by one, so that the problem of structural interference between adjacent clamp assemblies 40 is avoided by setting a part of the mounting surfaces M without setting the clamp assemblies 40.

[0048] The driving assembly 20 is configured to: drive the rotating bracket 30 to rotate, so that a designated one of the plurality of clamp assemblies 40 rotates to the side of the rotating bracket 30 away from the mounting frame 10. Here, the side of the rotating bracket 30 away from the mounting frame 10 can facilitate the implementation of subsequent processes. For example, welding and other processes are performed on other components. Therefore, the driving assembly 20 can drive the rotating bracket 30 to rotate, and drive the clamp assembly 40 to rotate to the side of the rotating bracket 30 away from the mounting frame 10, so that the effect of quickly switching the clamp assembly 40 can be achieved.

[0049] In summary, the embodiment of the present application provides a clamp device, wherein a plurality of mounting surfaces are arranged in the circumference of the rotating bracket, and a plurality of clamp assemblies of different types correspond to the plurality of mounting surfaces, and the clamp assemblies can be mounted on the corresponding mounting surfaces, so that the effect of integrating a plurality of clamp assemblies into the same device can be achieved, and the cost of a plurality of clamp assemblies can be reduced. Moreover, by driving the driving assembly to rotate between the rotations, the required clamp assembly can be quickly rotated to the side of the rotating bracket away from the mounting frame for subsequent processes, thereby improving the switching efficiency of the clamp assembly, and further improving the production efficiency.

[0050] In the present application, the fixture device can be used in the manufacturing process of the body-in-white frame, which refers to the structural part of the automobile body, including the body frame and body panels. Among them, the body frame is usually made of high-strength steel or aluminum alloy materials, which plays the role of supporting and bearing the body. The body panels are covered on the frame, including doors, front and rear covers and other parts. Therefore, the fixture assembly in the fixture device provided in the present application can be used as a welding fixture for doors, front and rear covers and other parts.

[0051] In an exemplary embodiment, please refer to Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the structure of another clamp device provided in an embodiment of the present application, Figure 3 yes Figure 2 A schematic diagram of a clamping device for clamping a component is provided, wherein the number of rotating brackets 30 is two, and the two rotating brackets 30 are distributed on both sides of the component L in the first direction X. Thus, the clamp assemblies 40 mounted on the two rotating brackets 30 are also distributed on both sides of the component L in the first direction X.

[0052] The two clamp assemblies 40 of the same type on the two rotating brackets 30 are used to clamp a type of component L. In this way, when the two clamp assemblies 40 of the same type are rotated to be located on the side of the rotating bracket 30 away from the mounting frame 10, the component L can be clamped and positioned. Exemplarily, the structures in the two clamp assemblies 40 of the same type can be symmetrically arranged, but the present application is not limited thereto.

[0053] It should be noted that Figure 2 The engine cover is taken as an example of the component L to be clamped, but the type of component L in the embodiment of the present application is not limited to this, and can be specifically set according to needs, and the structure of the clamp assembly 40 can also be set according to the component L to be clamped.

[0054] Optionally, the clamp assembly 40 includes: a mounting substrate 41 , and an adsorption portion 42 and a positioning portion 43 fixed on the mounting substrate 41 .

[0055] The mounting substrate 41 is mounted on the mounting surface M. Exemplarily, the mounting substrate 41 can be fixed to the mounting surface M by means of screws or other connectors, so that the fixture assembly 40 can be detachable. The mounting substrate 41 can be used to provide a flat bearing surface for other structures in the fixture assembly 40, such as the adsorption portion 42 and the positioning portion 43.

[0056] The adsorption portion 42 is used to adsorb the component L. When the fixture assembly 40 clamps the component L, the adsorption portion 42 can fix the component L, and the adsorption portion 42 can ensure that the component L does not move, thereby improving the positioning accuracy of the fixture assembly 40 for the component L.

[0057] The positioning portion 43 is used to position the component L in the first direction X and / or the second direction Y. The first direction X intersects the second direction Y. Here, when the clamp assembly 40 clamps the component L, the positioning portion 43 can abut against the edge of the component L in the first direction X and / or the second direction Y to achieve the positioning of the component L, thereby improving the positioning accuracy.

[0058] Optionally, the positioning portion 43 includes: at least one first positioning structure 431 and at least two second positioning structures 432. That is, the number of the first positioning structures 431 in the positioning portion 43 can be one or more, and the number of the second positioning structures 432 in the positioning portion 43 can be two or more than two. Exemplarily, Figure 2 The positioning portion 43 shown includes two first positioning structures 431 and two second positioning structures 432 .

[0059] Among them, at least two first positioning structures 431 in the two clamp assemblies 40 of the same type on the two rotating brackets 30 are used to position the component L in the first direction X. Here, since the two rotating brackets 30 are distributed on both sides of the component L in the first direction X, the first positioning structures 431 in the two clamp assemblies 40 of the same type on the two rotating brackets 30 can cooperate with the edges of both sides of the component L in the first direction X to achieve the positioning of the component L in the first direction X.

[0060] For any one of the two clamp assemblies 40 of the same type on the two rotating brackets 30, at least two second positioning structures 432 in the clamp assembly 40 are used to position the component L in the second direction Y. Here, the at least two second positioning structures 432 can abut against the edges of both sides of the component L in the second direction Y to achieve positioning of the component L in the second direction Y.

[0061] In addition, the positioning portion 43 may also include: a plurality of mounting bases 433 mounted on the mounting substrate 41, and the first positioning structure 431 and the second positioning structure 432 may be fixedly mounted on the mounting substrate 41 through the mounting bases 433 to adapt to the size of the components L of various vehicle models.

[0062] Optionally, the adsorption portion 42 includes: a plurality of suction cups 421. The plurality of suction cups 421 can provide suction to the component L, thereby improving the fixing effect of the component L and avoiding the need for heavy clamping mechanisms such as cylinders, thereby simplifying the structure of the clamp assembly 40.

[0063] In the first direction X, the multiple suction cups 421 in the same clamp assembly 40 are located on a side closer to another clamp assembly 40 of the same type relative to at least one first positioning structure 431. In the second direction Y, the multiple suction cups 421 in the same clamp assembly 40 are distributed between at least two second positioning structures 432. In this way, it can be ensured that the multiple suction cups 421 can contact the component L to be clamped, so that the component L can be adsorbed and fixed.

[0064] For example, Figure 2 The number of suction cups 421 in the suction part 42 shown is three, but the present application is not limited thereto. In addition, the multiple suction cups 421 in the suction part 42 can be evenly distributed in both the first direction X and the second direction Y, so that the suction force of the multiple suction cups 421 on the component L is more dispersed and balanced, which can improve the fixing effect of the suction part 42.

[0065] Optionally, the clamp assembly 40 further includes: a supporting portion 44 and a sensing portion 45 fixed on the mounting substrate.

[0066] The support portion 44 is used to support the component L. The support portion 44 can provide a supporting force to the component L to ensure the force balance when the component L is clamped by the clamp assembly 40. In the first direction X, the support portion 44 can be located on a side closer to another clamp assembly 40 of the same type relative to at least one first positioning structure 431. In the second direction Y, the support portion 44 is distributed between at least two second positioning structures 432. Exemplarily, Figure 2The number of the supporting parts 44 in the clamp assembly 40 shown is one, but the embodiment of the present application does not limit the number of the supporting parts 44, and the number of the supporting parts 44 in the clamp assembly 40 can also be multiple.

[0067] The sensing part 45 is used to sense whether the component L is set on the fixture assembly 40. Exemplarily, the sensing part 45 can be a contact sensor, and when the sensing part 45 contacts the component L, an electrical signal can be fed back to the control component, and the control component can respond to the electrical signal to control the fixture device 00 to clamp and position the component L, so as to facilitate the implementation of subsequent processes such as welding.

[0068] Optionally, refer to Figure 2 and Figure 4 , Figure 4 yes Figure 2 A side view schematic diagram of the structure of the clamp device is provided. The mounting frame 10 includes: a base 11 and a mounting frame body 12 fixedly connected to the base 11.

[0069] The base 11 can be fixed on the ground, and a balancing structure 13 can be provided on the base 11 to adjust the position of the mounting frame 10 and ensure that the clamp device 00 as a whole can be in a horizontal state, so as to adapt to various ground flatness conditions, avoid uneven ground that may cause burden and damage to the rotating bracket 30 and the driving assembly 20, and thus improve the stability of the clamp device 00 during use. Exemplarily, the balancing structure 13 can be a balancing bolt.

[0070] The mounting frame body 12 is used to install structures such as the rotating bracket 30 and the driving assembly 20. In order to improve the stability of the clamp device 00 during use, the mounting frame body 12 can be a triangular structure. Exemplarily, the mounting frame body 12 may include: a first frame and a second frame, wherein the first frame is fixed on the base 11, and the extension direction of the first frame is perpendicular to the plane where the base 11 is located, and the second frame is connected to the first frame, and the extension direction of the second frame is an acute angle with the plane where the base 11 is located. Here, the extension direction of the second frame is the extension direction of the main part of the second frame, and the two ends of the second frame are bent to facilitate connection with the rotating bracket 30.

[0071] The rotating bracket 30 is rotatably connected to the mounting bracket body 12, and the angle between the extending direction of the rotating bracket 30 and the surface where the base 11 is located is an acute angle. Here, by setting the mounting bracket body 12 to be a triangular structure, the angle between the extending direction of the rotating bracket 30 and the surface where the base 11 is located can be an acute angle. In this case, not only can the stability of the rotating bracket 30 be ensured during rotation, but also the position of the parts can be ensured not to affect the implementation of subsequent processes.

[0072] In addition, a third sensor 14 and a safety latch 15 may be provided on the mounting frame body 12, wherein the third sensor 14 may be used to sense whether the rotating bracket 30 is rotating and feed back the sensing result to the control component. The safety latch 15 may be used to ensure that the rotating bracket 30 does not rotate in a non-working state.

[0073] Optionally, refer to Figure 4 and Figure 5 , Figure 5 yes Figure 2 A partial enlarged schematic diagram of the provided fixture equipment ( Figure 5 Can be Figure 2 The clamp device 00 also includes: a control component ( Figure 4 and Figure 5 (not shown), a position sensing block 50 and a plurality of sets of sensors 60.

[0074] The position sensing block 50 is fixedly connected to one end of the rotating bracket 30. In this way, the position sensing block 50 can rotate with the rotating bracket 30, and the position of the position sensing block 50 can reflect the rotation of the rotating bracket 30. The driving assembly 20 can be connected to the other end of the rotating bracket 30 to avoid structural conflict with the sensor 60 and the position sensing block 50.

[0075] Multiple sets of sensors 60 are fixed on the mounting frame body 12 and are distributed around the circumference of the rotating bracket 30. The multiple sets of sensors 60 correspond to multiple clamp assemblies 40. The multiple sets of sensors 60 and the driving assembly 20 are both connected to the control assembly in communication. Here, the multiple sets of sensors 60 are distributed on one side where the rotating bracket 30 is connected to the position sensing block 50, so that the sensors 60 can cooperate with the position sensing block 50.

[0076] Multiple sets of sensors 60 may correspond to multiple fixture assemblies 40 one by one, and one set of sensors 60 reflects the rotation position of a corresponding fixture assembly 40. Figure 5 The rotating bracket 30 shown has four mounting surfaces M, each mounting surface M can be respectively mounted with a clamp assembly 40 , and the number of groups of sensors 60 can be four.

[0077] The control component is configured to control the rotating bracket 30 to stop rotating through the driving component 20 after a designated group of sensors 60 corresponding to a designated clamp component 40 detects the position sensing block 50 .

[0078] Since the sensor 60 can cooperate with the sensing block 50 to determine the position of a specified clamp assembly 40, it can be determined whether the specified clamp assembly 40 is rotated to the side of the rotating bracket 30 away from the mounting frame 10, that is, whether the specified clamp assembly 40 is rotated into place, so that the control component can control the driving component 20 based on the detection result of the sensor 60. Such control has high accuracy and can improve the positioning accuracy of the clamp device 00.

[0079] In the present application, the driving assembly 20 may include: a driving motor 21 and a reducer 22, wherein the driving motor 21 may provide a driving force for rotation to the rotating bracket 30, and the reducer 22 may control the rotation speed of the driving motor to control the stop position of the rotating bracket 30. The reducer 22 may be connected to the rotating bracket 30, and a dust cover 23 may be provided at the connection position, and the dust cover 23 may prevent welding slag and dust from damaging the connection rotation position.

[0080] Optionally, each group of sensors 60 includes: a first sensor 61 and a second sensor 62. Here, during the rotation of the rotating bracket 30, along the circumference of the rotating bracket 30, the first sensor 61 in the same group is closer to the position sensing block 50 than the second sensor 62, that is, for each group of sensors 60 in the same group, the position sensing block 50 will first trigger the first sensor 61 and then trigger the second sensor 62.

[0081] Among them, after the first sensor 61 in the designated group of sensors 60 detects the position sensing block 50, the control component is used to send a deceleration signal to the driving component 20. At this time, the designated clamp component 40 has not yet rotated to the position, but is close to the position to be rotated, so the control component can send a deceleration signal to the reducer 22 to decelerate the rotating bracket 30, reduce inertia, and avoid the rotating bracket 30 from rotating too far, thereby improving the positioning accuracy when switching the clamp component 40.

[0082] After the second sensor 62 in the designated group of sensors 60 detects the position sensing block 50, the control component is used to send a stop signal to the drive component 20. At this time, the designated clamp component 40 has been rotated to the right position, so the control component can send a stop signal to the drive motor 21 to stop the rotating bracket 30 from rotating, thereby preventing the rotating bracket 30 from rotating too far, thereby improving the positioning accuracy when switching the clamp component 40.

[0083] Optionally, the fixture device 00 also includes: multiple groups of laser positioning components 70 fixed on the base 11, the multiple groups of laser positioning components 70 correspond to multiple fixture components 40, and the laser emitted by one group of laser positioning components 70 can be emitted to the component L clamped by the corresponding fixture component 40.

[0084] The laser positioning assembly 70 may include: multiple light sources. When the lasers emitted by the multiple light sources are projected onto the component L clamped by the corresponding fixture assembly 40, the positions of structures such as adhesive stickers and adhesive blocks on the component L can be determined, so that there is no need to set corresponding positioning mechanisms for adhesive stickers and adhesive blocks in the fixture assembly 40, which reduces the complexity of the fixture and avoids setting positioning holes. Multiple groups of laser positioning assemblies 70 can be set on the column 71 to ensure that the lasers emitted by the laser positioning assembly 70 can be projected onto the component L. The column 71 can be set on the base 11 and distributed on the side away from the mounting frame body 12.

[0085] For example, Figure 2 As shown, the laser positioning assembly 70 can locate the pasting position of the enhancement sticker T. A set of laser positioning assemblies 70 includes two light sources, and the lasers emitted by the light sources are used to determine two points on the diagonal line of the enhancement sticker.

[0086] It should be noted that Figure 2 A group of laser positioning components 70 is taken as an example, but the embodiment of the present application is not limited to this. The embodiment of the present application can be a laser positioning component 70 respectively set for multiple clamp assemblies 40 to adapt to the differences in the pasting positions of structures such as stickers and rubber blocks in the parts L of different vehicle models.

[0087] The fixture device 00 provided in the embodiment of the present application can be used to realize fully automatic switching of fixture components of different vehicle models. The operation process of the fixture device 00 is described below with an example:

[0088] The control component can obtain the production order in the production planning IoT system, and determine a designated fixture component 40 corresponding to the current vehicle model to be produced based on the production order. The control component can control the drive component 12 to drive the rotating bracket 30 to rotate, and after the sensor 60 detects that a designated fixture component 40 rotates to the side of the rotating bracket 30 away from the mounting frame 10, production is carried out. In this way, the fixture device 00 realizes the fully automatic switching of fixture components 40 of multiple vehicle models, avoiding the problem of high labor intensity of manual switching, and effectively improving production efficiency.

[0089] In summary, the embodiment of the present application provides a clamp device, wherein a plurality of mounting surfaces are arranged in the circumference of the rotating bracket, and a plurality of clamp assemblies of different types correspond to the plurality of mounting surfaces, and the clamp assemblies can be mounted on the corresponding mounting surfaces, so that the effect of integrating a plurality of clamp assemblies into the same device can be achieved, and the cost of a plurality of clamp assemblies can be reduced. Moreover, by driving the driving assembly to rotate between the rotations, the required clamp assembly can be quickly rotated to the side of the rotating bracket away from the mounting frame for subsequent processes, thereby improving the switching efficiency of the clamp assembly, and further improving the production efficiency.

[0090] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0091] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is also understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer.
