Clamping device and vehicle detection equipment

Abstract

The utility model relates to the technical field of vehicle detection, in particular to a clamping device and vehicle detection equipment. The supporting piece abuts against the surface of one side of the workpiece, and when the clamping part abuts against the surface of the other side of the workpiece, the supporting piece and the clamping piece abut against the workpiece to clamp the workpiece. And when the clamping part is separated from the surface of the other side of the workpiece, the clamping part and the supporting piece are matched to loosen the workpiece. Due to the fact that the second connecting rod is arranged between the clamping part and the pushing piece, the pushing piece is stressed to drive the clamping part to clamp the workpiece through the second connecting rod, the second connecting rod can provide the length of the clamping part extending towards the narrow space, and the clamping part and the supporting part are connected in a bent mode. Therefore, the clamping part can extend into a narrow space (such as a cavity between an outer plate metal plate and an inner plate) and then is matched with a supporting piece to clamp a workpiece. Therefore, under the synergistic effect of the first connecting rod and the second connecting rod, the clamping part can stretch into a narrow space to clamp a workpiece.

Description

Technical Field

[0001] This utility model relates to the technical field of vehicle inspection, specifically to a clamping device and vehicle inspection equipment. Background Technology

[0002] Inspection of automotive parts quality is inseparable from fixtures. Fixtures typically consist of three parts: a base, a clamping device, and a testing device. However, due to limitations in product structure and space, conventional clamping devices often cannot achieve the desired clamping effect. For example, the product positioning support points of a door assembly are distributed on the inner panel, while the door assembly includes an outer panel. This creates a cavity between the inner and outer panels, and the product is surrounded by the testing device. To clamp directly onto the support points, it is necessary to first contact the outer panel. However, the outer panel sheet metal is usually quite thin, and clamping may cause deformation and damage to the product. Therefore, a clamping device is needed that can clamp without damaging the door structure. Utility Model Content

[0003] The purpose of this application is to provide a clamping device and a vehicle inspection equipment.

[0004] This application provides a clamping device, comprising: a support member, a first bracket, a first connecting rod, a pushing member, a second bracket, and a second connecting rod; the support member is used to abut against one side surface of a workpiece; the pushing member includes a connecting portion, a pushing portion, and a first bent portion, the first bent portion being located between the connecting portion and the pushing portion, the first bent portion being rotatably connected to the first bracket to form a first rotational support point, the connecting portion being rotatably connected to the first connecting rod, and the pushing portion being subjected to force to rotate around the first rotational support point, causing the connecting portion to drive the first connecting rod to move; the second connecting rod includes a support portion, The clamping part and the second bending part are located between the clamping part and the supporting part. The supporting part is rotatably connected to the second bracket to form a second rotating support point. The supporting part is rotatably connected to the side of the first connecting rod away from the connecting part. The second rotating support point is located between the first connecting rod and the second bending part. The movement of the first connecting rod causes the supporting part to rotate around the second rotating support point, thereby causing the clamping part to rotate. The side of the clamping part away from the second bending part is close to or away from the workpiece, and is used to abut or detach from the workpiece on the other side surface away from the supporting part.

[0005] In one exemplary embodiment of this application, the first bracket further includes a connecting plate, a support column, and a limiting plate. One side of the connecting plate is fixedly connected to the support column, and the other side of the connecting plate is rotatably connected to the first bent portion. The limiting plate is disposed on the connecting plate and is located between the first bent portion and the support column. The connecting portion is away from or close to the limiting plate.

[0006] In one exemplary embodiment of this application, there are two connecting plates, which are spaced apart, and the connecting portion is located at the interval between the two connecting plates; the support column forms a through hole; the connecting portion forms a first gap; the first connecting rod passes through the through hole and the first gap and is rotatably connected to the connecting portion.

[0007] In one exemplary embodiment of this application, the first link includes a first link portion and a second link portion, which are rotatably connected.

[0008] In one exemplary embodiment of this application, the clamping portion includes an integrally formed first clamping portion, a second clamping portion, and a third clamping portion. The first clamping portion, the second clamping portion, and the third clamping portion are sequentially connected from the side away from the second bend portion to the side closer to the second bend portion. The first clamping portion and the third clamping portion are horizontally arranged in the same direction, and the second clamping portion is obliquely connected between the first clamping portion and the third clamping portion.

[0009] In one exemplary embodiment of this application, the first clamping portion is close to the workpiece, and the second clamping portion is away from the workpiece. The clamping portion further includes a rubber chuck, which is disposed on the first clamping portion and corresponds to the support member.

[0010] In an exemplary embodiment of this application, the support portion includes an integrally formed first support portion, a second support portion, and a third support portion. The first support portion, the second support portion, and the third support portion are sequentially connected from the side away from the second bending portion to the side closer to the second bending portion. The first support portion is arranged at a right angle to the third clamping portion, the second support portion is arranged at an angle to the first support portion, and the third support portion is arranged at an angle to the second support portion. A third bending portion is formed between the second support portion and the third support portion, and the third bending portion protrudes toward the clamping portion.

[0011] In one exemplary embodiment of this application, the first bracket and the first connecting rod are both rotatably connected to the third support portion.

[0012] In one exemplary embodiment of this application, the clamping device further includes a limiting member disposed on the second bracket, the limiting member being located on the side of the support portion opposite to the clamping portion.

[0013] The clamping device and vehicle inspection equipment disclosed in this application have the following advantages: A connecting part is connected to one side of the first connecting rod, and a supporting part is connected to the other side of the first connecting rod. When the pushing part is subjected to force and rotates around a first rotating support point, it causes the connecting part to rotate simultaneously, thus moving the first connecting rod. This, in turn, causes the supporting part to rotate around a second rotating support point via the first connecting rod, and the clamping part also rotates around the second rotating support point. The clamping part moves closer to or further away from the workpiece on the side away from the second bent part. Specifically, the supporting member abuts against one surface of the workpiece. When the clamping part abuts against the other surface of the workpiece, the workpiece is clamped by the support member and the clamping member. When the clamping part disengages from the other surface of the workpiece, the clamping part and the supporting member cooperate to release the workpiece. Because there is a second link between the clamping part and the pushing part, the force applied to the pushing part drives the clamping part to clamp the workpiece via the second link. The second link provides the length for the clamping part to extend into confined spaces, and the clamping part and the support part are connected by a bend. Therefore, the clamping part can extend into confined spaces (such as the cavity between the outer sheet metal and the inner panel), and then, in conjunction with the support part, clamp the workpiece. Thus, under the synergistic action of the first and second links, the clamping part can extend into confined spaces to clamp the workpiece.

[0014] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0015] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0028] Inspection of automotive parts quality is inseparable from fixtures. Fixtures typically consist of three parts: a base, a clamping device, and a testing device. However, due to limitations in product structure and space, conventional clamping devices often cannot achieve the desired clamping effect. For example, the product positioning support points of a door assembly are distributed on the inner panel, while the door assembly includes an outer panel. This creates a cavity between the inner and outer panels, and the product is surrounded by the testing device. To clamp directly onto the support points, it is necessary to first contact the outer panel. However, the outer panel sheet metal is usually quite thin, and clamping may cause deformation and damage to the product. Therefore, a clamping device is needed that can clamp without damaging the door structure.

[0029] To solve the above technical problems, refer to Figures 1 to 4 As shown, this application provides a clamping device 2, which includes a support member 10, a first bracket 20, a first connecting rod 30, a pusher 40, a second bracket 50, and a second connecting rod 60; the support member 10 is used to abut against one side surface of the workpiece 1; see details below. Figure 3 As shown, the pushing member 40 includes a connecting part 41, a pushing part 42, and a first bent part 43. The first bent part 43 is located between the connecting part 41 and the pushing part 42. The first bent part 43 is rotatably connected to the first bracket 20 to form a first rotational support point S1. The connecting part 41 is rotatably connected to the first connecting rod 30. The pushing part 42 is subjected to force and rotates around the first rotational support point S1, causing the connecting part 41 to drive the first connecting rod 30 to move. See details. Figure 4 As shown, the second connecting rod 60 includes a support part 61, a clamping part 62, and a second bending part 63. The second bending part 63 is located between the clamping part 62 and the support part 61. The support part 61 is rotatably connected to the second bracket 50 to form a second rotating support point S2. The support part 61 is rotatably connected to the side of the first connecting rod 30 away from the connecting part 41. The second rotating support point S2 is located between the first connecting rod 30 and the second bending part 63. The movement of the first connecting rod 30 drives the support part 61 to rotate around the second rotating support point S2, thereby driving the clamping part 62 to rotate. The side of the clamping part 62 away from the second bending part 63 approaches or moves away from the workpiece 1, and is used to abut or disengage from the other side surface of the workpiece 1 away from the support member 10.

[0030] Reference Figures 1 to 4As shown, one side of the first connecting rod 30 is connected to the connecting part 41, and the other side of the first connecting rod 30 is connected to the support part 61. The pushing part 42 is subjected to force and rotates around the first rotating support point S1, causing the connecting part 41 to rotate simultaneously. This causes the connecting part 41 to move the first connecting rod 30, thereby causing the support part 61 to rotate around the second rotating support point S2 through the first connecting rod 30. The clamping part 62 also rotates around the second rotating support point S2. The clamping part 62 moves closer to or further away from the workpiece 1 on the side away from the second bent part 63. The support member 10 abuts against one side surface of the workpiece 1. When the clamping part 62 abuts against the other side surface of the workpiece 1, the workpiece 1 is clamped by the support member 10 and the clamping member. When the clamping part 62 disengages from the other side surface of the workpiece 1, the clamping part 62 and the support member 10 cooperate to release the workpiece 1. Because there is a second connecting rod 60 between the clamping part 62 and the pushing member 40, the pushing member 40 is forced to drive the clamping part 62 to clamp the workpiece 1 via the second connecting rod 60. The second connecting rod 60 can provide the length for the clamping part 62 to extend into a narrow space, and the clamping part 62 and the supporting part 61 are connected by a bend. Therefore, the clamping part 62 can extend into a narrow space (such as the cavity between the outer sheet metal and the inner panel), and then work with the supporting member 10 to clamp the workpiece 1. Thus, under the synergistic action of the first connecting rod 30 and the second connecting rod 60, the clamping part 62 can be extended into a narrow space to clamp the workpiece 1.

[0031] In some embodiments, workpiece 1 includes a car door, a body sheet metal part, etc. In this application, a car door is mainly used as an example for description. The car door includes an outer door panel and an inner door panel, and a cavity is formed between the outer door panel and the inner door panel. The inner door panel is provided with mounting holes for installing other parts. The clamping part 62 can extend into the cavity from the mounting holes. There are many similar structures to the car door cavity in vehicles, and workpiece 1 with similar structures in other fields will not be listed here.

[0032] In some embodiments, the support member 10, the first bracket 20 and the second bracket 50 are mounted on the same base (not shown in the figure), and multiple clamping devices 2 can be provided on the base, depending on actual needs.

[0033] In some embodiments, refer to Figures 1 to 4 As shown, when the clamping device 2 clamps, the pushing part 42 is subjected to force and rotates counterclockwise, driving the second connecting rod 60 to move to the left in the first direction through the connecting part 41. The second connecting rod 60 pushes the supporting part 61 to rotate clockwise around the second rotational support point S2, thereby bringing the clamping part 62 closer to the workpiece 1 and cooperating with the support member 10 to clamp the workpiece 1. When the clamping device 2 is released, the pushing part 42 is subjected to force in the opposite direction and rotates clockwise, causing the second connecting rod 60 to move to the right in the first direction. The second connecting rod 60 drives the supporting part 61 to rotate counterclockwise around the second rotational support point S2, thereby moving the clamping part 62 away from the workpiece 1, so that the clamping device 2 is released from the workpiece 1.

[0034] In some embodiments, refer to Figure 2 As shown, the clamping device 2 also includes a limiting member 70, which is disposed on the second bracket 50 and located on the side of the support portion 61 opposite to the clamping portion 62. The limiting member 70 is used to limit the rotation stroke of the support portion 61 to prevent the support portion 61 from rotating excessively and colliding with the second bracket 50. Specifically, the limiting member 70 can also be a rubber limiting member.

[0035] In some embodiments, refer to Figure 2 As shown, the first link 30 includes a first link portion 31 and a second link portion 32, which are rotatably connected. Since the pusher 40 rotates to move the first link 30, the movement of the first link 30 may result in the right side being higher than the left side in the first direction. The rotatable connection between the first link portion 31 and the second link portion 32 allows for greater movement space and increases the stroke of the first link 30.

[0036] In some embodiments, combined with Figure 2 and Figure 4 As shown, the clamping part 62 includes a first clamping part 621, a second clamping part 622, and a third clamping part 623 integrally formed. The first clamping part 621, the second clamping part 622, and the third clamping part 623 are connected sequentially from the side away from the second bend 63 to the side closer to the second bend 63. The first clamping part 621 and the third clamping part 623 are arranged horizontally in the same direction, and the second clamping part 622 is obliquely connected between the first clamping part 621 and the third clamping part 623. In the second direction, the height of the first clamping part 621 is smaller than that of the second clamping part 622, which can reduce the risk of interference between the clamping part 62 and the workpiece 1.

[0037] In some embodiments, combined with Figure 2 and Figure 4 As shown, the first clamping part 621 is close to the workpiece 1, and the second clamping part 622 is away from the workpiece 1. The clamping part 62 also includes a rubber chuck 624, which is disposed on the first clamping part 621 and corresponds to the support member 10. The rubber chuck 624 on the first clamping part 621 has better toughness, preventing the clamping part 62 from damaging the workpiece 1.

[0038] In some embodiments, combined with Figure 2 and Figure 4As shown, the support portion 61 includes an integrally formed first support portion 611, second support portion 612, and third support portion 613. The first support portion 611, second support portion 612, and third support portion 613 are sequentially connected from the side furthest from the second bend portion 63 to the side closest to the second bend portion 63. The first support portion 611 is set at a right angle to the third clamping portion 613, the second support portion 612 is set at an angle to the first support portion 611, and the third support portion 613 is set at an angle to the second support portion 612. A third bend portion 614 is formed between the second support portion 612 and the third support portion 613, and the third bend portion 614 protrudes towards the clamping portion 62. The third bend portion 614 between the second support portion 612 and the third support portion increases the rotational stroke of the support portion 61, giving the clamping portion 62 a larger clamping stroke. Specifically, the first bracket 20 and the first connecting rod 30 are both rotatably connected to the third support portion 613.

[0039] In some embodiments, refer to Figure 5 As shown, the first bracket 20 also includes a connecting plate 21, a support column 22, and a limiting plate 23. One side of the connecting plate 21 is fixedly connected to the support column 22, and the other side of the connecting plate 21 is rotatably connected to the first bent portion 43. The limiting plate 23 is disposed on the connecting plate 21 and is located between the first bent portion 43 and the support column 22. The connecting portion 41 is either away from or close to the limiting plate 23. The supporting column 22 and the pushing member 40 are connected by the connecting plate 21. The limiting plate 23 is located below the connecting plate 21 in the second direction. When the pushing member 40 rotates counterclockwise, the connecting portion 41 is limited by the limiting plate 23, which keeps the first connecting rod 30 in the displacement position on the left side to keep the clamping portion 62 clamping the workpiece 1. When the pushing member 40 rotates clockwise, the connecting portion 41 moves away from the limiting plate 23, and the pushing portion 42 may be limited by the limiting plate 23 to limit the displacement of the first connecting rod 30 to the right. The first bracket 20 can support the pusher 40 to provide a first rotational support point S1 between the pusher 40 and the first bracket 20, and can also limit the pusher 40 through the limiting plate 23.

[0040] In some embodiments, refer to Figure 5 As shown, there are two connecting plates 21, spaced apart, with a connecting part 41 located at the gap between the two connecting plates 21; the support column 22 forms a through hole 221; the connecting part 41 forms a first gap 411; the first connecting rod 30 passes through the through hole 221 and the first gap 411, and is rotatably connected to the connecting part 41. The first connecting rod 30 passing through the through hole 221 can reduce the risk of large swaying of the second connecting rod 60, and the first gap 411 can provide clearance when the first connecting rod 30 rotates, so that the end of the first connecting rod 30 does not interfere with the connecting part 41.

[0041] In this application, when the clamping device 2 is released, the pushing part 42 is subjected to a reverse force and rotates clockwise, causing the second connecting rod 60 to move to the right in the first direction. The second connecting rod 60 drives the supporting part 61 to rotate counterclockwise around the second rotational support point S2, thereby moving the clamping part 62 away from the workpiece 1, so that the clamping device 2 can be released from the workpiece 1. Under the coordinated action of the supporting part 10, the first bracket 20, the first connecting rod 30, the pushing part 40, the second bracket 50, and the second connecting rod 60, the clamping part 62 can be extended into a narrow space to clamp the workpiece 1. This saves inspection time for the workpiece 1 and increases the inspection efficiency of the workpiece 1.

[0042] This application also provides a vehicle inspection device, including a clamping device 2.
