Description

Technical Field

[0001] This utility model relates to the field of automotive tooling fixture technology, specifically to a flexible fixture. Background Technology

[0002] In the process of vehicle manufacturing development, the demand for intelligent welding production lines for newly developed models is increasing.

[0003] To facilitate the welding of different vehicle models, the related technology provides an automated welding line and welding production method for the front wheel arch assembly of the body-in-white. When it is necessary to switch to the production of the fifth vehicle model, the motor drive switches the fixture of the vehicle model not being produced on the turntable to the switching position. Then, the fixture storage trolley outside the line docks with the fixture library switching position, and the motor drive drags the switching fixture onto the switching trolley. The switching trolley of the fifth vehicle model fixture docks with the switching device, and the motor drive drags the fifth vehicle model onto the turntable.

[0004] However, the device requires different types of clamps to adapt to different vehicle models, which results in multiple clamps occupying too much space and having excessively high processing costs. Utility Model Content

[0005] The purpose of this invention is to provide a flexible fixture to solve the problems of excessive space occupied and high processing costs of multiple fixtures in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flexible clamp includes a base, a first clamping assembly, a second clamping assembly, a limiting assembly, and a first moving member. The first clamping assembly is fixedly connected to the base. The second clamping assembly is movably connected to the base. Along a first direction, the second clamping assembly is disposed on one side of the first clamping assembly. The limiting assembly is connected to the base, and along the first direction, the limiting assembly is located between the second clamping assembly and the first clamping assembly; and along a second direction, the limiting assembly is located on the same side of the first and second clamping assemblies. The second direction is perpendicular to the first direction. The first moving member is connected between the base and the second clamping assembly. The first moving member is capable of moving the second clamping assembly along the first direction or a third direction. The third direction is perpendicular to the first direction and also perpendicular to the second direction.

[0007] According to the above technical means, by moving the second clamping component through the first moving component, the distance between the second clamping component and the first clamping component can be adjusted, and the distance between the second clamping component and the base can be adjusted, so that the clamping position of the second clamping component moves relative to the clamping position of the first clamping component, and adapts to different types of components to be fixed.

[0008] In this way, when the flexible fixture fixes different types of parts, the position of the second clamping component can be adjusted by the first moving component, so that the clamping component can fix different types of parts. Compared with processing various types of fixtures with corresponding fixtures and then switching between different fixtures by means of structures such as hubs, turntables or cross slides, the flexible fixture provided in this application has a simple structure, occupies less space, is easy to install, and can also reduce the processing cost of the fixture.

[0009] Furthermore, the flexible fixture also includes a second movable member, which is connected between the base and the limiting assembly. The second movable member can drive the limiting assembly to move along a second direction.

[0010] According to the above-mentioned technical means, the second moving part can drive the limiting component to move, thereby clamping the first clamping component and the second clamping component to a suitable position on the component to be fixed.

[0011] Furthermore, the first clamping assembly includes a first clamping arm, a first driving member, and a second clamping arm. The first clamping arm is fixed to the base. The second clamping arm is located on the side of the first clamping arm away from the base, and the first driving member is convexly connected to the second clamping arm for driving the second clamping arm to move in a third direction. And / or, the second clamping assembly includes a third clamping arm, a second driving member, and a fourth clamping arm. The third clamping arm is fixed to the base. The fourth clamping arm is located on the side of the third clamping arm away from the base, and the second driving member is convexly connected to the fourth clamping arm for driving the fourth clamping arm to move in a third direction.

[0012] According to the above technical means, the second clamping arm can be driven by the first driving member to move closer to the first clamping arm, thereby clamping the part to be fixed between the first and second clamping arms, and fixing the part to be fixed by the first and second clamping arms. Simultaneously, the arrangement of the first and second clamping arms provides a large installation space around them, facilitating the movement of the part to be fixed to the first clamping assembly for fixation. Alternatively, the fourth clamping arm can be driven by the second driving member to move closer to the third clamping arm, thereby clamping the part to be fixed between the third and fourth clamping arms, and fixing the part to be fixed by the third and fourth clamping arms. Simultaneously, the arrangement of the third and fourth clamping arms provides a large installation space around them, facilitating the movement of the part to be fixed to the second clamping assembly for fixation.

[0013] Furthermore, the first clamping assembly further includes a first support member and a first fastener. The first support member is located between the first clamping arm and the second clamping arm, and is connected to the end of the first clamping arm near the second clamping assembly. The first fastener is located between the first clamping arm and the second clamping arm, and is connected to the end of the second clamping arm near the second clamping assembly. The first fastener and the first support member are arranged sequentially along a third direction, and both the first fastener and the first support member are spherical. And / or, the second clamping assembly further includes a second support member and a second fastener. The second support member is located between the third clamping arm and the fourth clamping arm, and is connected to the end of the third clamping arm near the second clamping assembly. The second fastener is located between the third clamping arm and the fourth clamping arm, and is connected to the end of the fourth clamping arm near the second clamping assembly. The second fastener and the second support member are arranged sequentially along a third direction, and both the second fastener and the second support member are spherical.

[0014] According to the above technical means, since both the first support member and the first fastener are located between the first clamping arm and the second clamping arm, the part to be fixed can be clamped by the first support member and the first fastener while the first drive member drives the second clamping arm to move towards the first clamping arm. Furthermore, compared to the first support member or the first fastener being block-shaped, when both the first support member and the first fastener are spherical, the spherical surface of the spherical structure contacts the part to be fixed, thus avoiding scratches and wear between the corners of the first support member or the first fastener and the part to be fixed, thereby protecting the part to be fixed and extending the service life of the first support member and the first fastener. Since both the second support member and the second fastener are located between the third clamping arm and the fourth clamping arm, the part to be fixed can be clamped by the second support member and the second fastener while the second drive member drives the fourth clamping arm to move towards the third clamping arm. Furthermore, compared to the second support member or the second fastener being block-shaped, when both the second support member and the second fastener are spherical, the spherical surface of the spherical structure contacts the part to be fixed. This can prevent the corners of the second support member or the second fastener from rubbing and wearing against the part to be fixed, thereby protecting the part to be fixed and extending the service life of the second support member and the second fastener.

[0015] Furthermore, the first moving member includes a first moving part and a second moving part. The first moving part is connected to the second clamping assembly and is used to drive the second clamping assembly to move along a third direction. The second moving part is connected between the first moving part and the base, and the second moving part is capable of driving the first moving part and the second clamping assembly to move along a first direction.

[0016] According to the above-mentioned technical means, the second clamping assembly can be moved along three directions and the first direction by the first moving part and the second moving part respectively. Compared with the first moving part including a robotic arm, the first moving part and the second moving part only need to move the second clamping assembly along a fixed direction. This simplifies the structure of the first moving part, facilitates the processing and installation of the first moving part, and reduces the processing cost of the flexible fixture.

[0017] Furthermore, there are two second clamping components, symmetrically arranged along the second direction. There are also two first moving parts, each corresponding to one of the two second clamping components. These first moving parts are also symmetrically arranged along the second direction.

[0018] According to the above technical means, two first moving parts can drive two second clamping components to move respectively, so as to adjust the position of the two second clamping components and ensure that both second clamping components can be connected to different types of objects to be fixed, thereby ensuring the fixing effect of the flexible fixture on different types of objects to be fixed.

[0019] Furthermore, the second moving part includes telescopic members, and the distance between the ends of the two telescopic members away from the first clamping assembly is greater than the distance between the ends of the two telescopic members close to the first clamping assembly.

[0020] According to the aforementioned technical means, as the two second moving parts drive the two second clamping components to move towards the two first clamping components, the distance between the two second clamping components gradually decreases. Thus, when the size of the part to be fixed is small, and the distance between the two second clamping components and the two first clamping components is small along the first direction, the distance between the two second clamping components is also small, ensuring that both second clamping components can clamp onto the part to be fixed, guaranteeing the fixing effect of the two second clamping components. Conversely, when the size of the part to be fixed is large, and the distance between the two second clamping components and the two first clamping components is large along the first direction, the distance between the two second clamping components is also large, ensuring sufficient distance between the two second clamping components in the second direction. This prevents the clamping positions of the two second clamping components from being too concentrated on the part to be fixed, thereby preventing the part to be fixed from flipping and ensuring the fixing effect of the two second clamping components. In this way, the two second clamping components can effectively fix different types of parts to be fixed, improving the fixing effect of the flexible fixture on different types of parts.

[0021] Furthermore, there are two of each of the first clamping component, the second clamping component, and the limiting component. Along the second direction, the two first clamping components, the two second clamping components, and the two limiting components are symmetrically arranged about the same plane.

[0022] According to the above technical means, compared to having only one first clamping component, one second clamping component, and one limiting component, when there are two first clamping components, two second clamping components, and two limiting components, the two first clamping components and the two second clamping components can simultaneously clamp the part to be fixed, thereby providing more stable support for the part to be fixed and improving the fixing effect of the flexible fixture. The two limiting components can simultaneously position the part to be fixed from both sides in the second direction, which can further improve the positioning accuracy of the flexible fixture when fixing the part to be fixed.

[0023] Furthermore, the first clamping assembly includes a first clamping arm, a first driving member, and a second clamping arm. The first clamping arm is fixed to the base. The second clamping arm is located on the side of the first clamping arm away from the base. The first driving member is convexly connected to the second clamping arm and is used to drive the second clamping arm to move in a third direction. The first and second clamping arms located on the same first clamping assembly extend in the same direction, and the distance between the ends of the two first clamping arms away from the second clamping assembly is greater than the distance between the ends of the two first clamping arms closer to the second clamping assembly.

[0024] According to the above technical means, the extension direction of the gap between the first clamping arm and the second clamping arm can be inclined towards the geometric center of the part to be fixed, and the gap between the first clamping arm and the second clamping arm can be extended for a long distance so as to fix the first clamping assembly to the part to be fixed and prevent the first clamping assembly and the part to be fixed from bumping or wearing each other.

[0025] Furthermore, the flexible fixture also includes two second moving parts, one of which is connected between the base and a limiting component. The second moving part can drive the corresponding limiting component to move along a second direction.

[0026] According to the above technical means, two second moving parts can drive two limiting components to move respectively, so as to adjust the position of the two limiting components at the same time. When the two limiting components contact and position different types of parts to be fixed at the same time, the first clamping component and the second clamping component can clamp the part to be fixed to a position close to the middle in the second direction, so as to avoid the part to be fixed from flipping on one side in the second direction, and further improve the fixing effect of the flexible fixture on different types of parts to be fixed.

[0027] The beneficial effects of this utility model are: The first moving component drives the second clamping component to move, which can adjust the distance between the second clamping component and the first clamping component, and can also adjust the distance between the second clamping component and the base, so that the clamping position of the second clamping component moves relative to the clamping position of the first clamping component, and can adapt to different types of components to be fixed.

[0028] In this way, when the flexible fixture fixes different types of parts, the position of the second clamping component can be adjusted by the first moving component, so that the clamping component can fix different types of parts. Compared with processing various types of fixtures with corresponding fixtures and then switching between different fixtures by means of structures such as hubs, turntables or cross slides, the flexible fixture provided in this application has a simple structure, occupies less space, is easy to install, and can also reduce the processing cost of the fixture.

[0031] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] In the process of vehicle manufacturing development, the demand for intelligent welding production lines for newly developed models is increasing. In order to facilitate welding processing of different models, welding fixtures are usually developed separately for each model. Then, the welding fixtures of different models can be switched through structures such as rotating hubs, turntables or cross slides. However, this will result in the welding fixtures occupying a large space and will increase the cost of vehicle production.

[0034] Based on this, such as Figure 1 As shown, this application provides a flexible clamp 10, which includes a base 6, a first clamping assembly 1, a second clamping assembly 2, and a limiting assembly 3. The first clamping assembly 1 is fixedly connected to the base 6. The second clamping assembly 2 is movably connected to the base 6. Along a first direction ( Figure 1 (in the X direction shown), the second clamping component 2 is disposed on one side of the first clamping component 1.

[0035] The limiting component 3 is connected to the base 6. Along the first direction, the limiting component 3 is located between the second clamping component 2 and the first clamping component 1, and along the second direction ( Figure 1 (As shown in the Y direction), the limiting component 3 is located on the same side of the first clamping component 1 and the second clamping component 2. The second direction is perpendicular to the first direction.

[0036] In the process of fixing the part to be fixed (such as the hood, wheel cover, or sheet metal parts of other equipment), the part to be fixed can be placed on the first clamping component 1 and the second clamping component 2, and the part to be fixed can be made to contact the limiting component 3, thereby positioning the part to be fixed. Then, the first clamping component 1 and the second clamping component 2 are used to clamp the part to be fixed, thereby achieving the positioning and fixing of the part to be fixed, so as to facilitate subsequent processing or treatment of the part to be fixed.

[0037] Based on this, such as Figure 1 As shown, the flexible clamp 10 also includes a first movable member 4, which is connected between the base 6 and the second clamping assembly 2. The first movable member 4 can drive the second clamping assembly 2 along a first direction or a third direction (…). Figure 1 The movement is in the Z direction (as shown in the diagram). The third direction is perpendicular to the first direction and also perpendicular to the second direction.

[0038] In this way, by moving the second clamping component 2 through the first moving component 4, the distance between the second clamping component 2 and the first clamping component 1 can be adjusted, and the distance between the second clamping component 2 and the base 6 can also be adjusted, so that the clamping position of the second clamping component 2 moves relative to the clamping position of the first clamping component 1, and adapts to different types of components to be fixed.

[0039] In this way, when the flexible fixture 10 fixes different types of parts to be fixed, the position of the second clamping component 2 can be adjusted by the first moving part 4, so that the clamping component can fix different types of parts to be fixed. Compared with processing various types of fixtures with corresponding parts and then switching different fixtures by means of structures such as hubs, turntables or cross slides, the flexible fixture 10 provided in this application has a simple structure, occupies less space, is easy to install, and can also reduce the processing cost of the fixture.

[0040] It should be noted that, taking a vehicle hood as an example, the first moving component 4 drives the second clamping component 2 to move along the first direction, which can adjust the distance between the second clamping component 2 and the first clamping component 1, so that the first clamping component 1 and the second clamping component 2 can jointly clamp different types of hoods. Furthermore, since different hoods have different thicknesses and degrees of curvature, to avoid collisions between the hood and the base 6 and to allow for sufficient operating space, the first moving component 4 can also drive the second clamping component 2 to move along the third direction, thus ensuring sufficient distance between the second clamping component 2 and the base 6, guaranteeing the fixation of the hood and facilitating its processing.

[0041] For example, the base 6 can be a substrate, with the thickness direction of the substrate aligned with the vertical direction. The base 6 can also be a worktable, etc.

[0042] For example, the first and second directions are both aligned with the horizontal direction, and the third direction is aligned with the vertical direction. Alternatively, the first and second directions both intersect the horizontal direction, and the third direction intersects the vertical direction.

[0043] In some other embodiments, the flexible clamp 10 may also include a third moving member connected between the first clamping assembly 1 and the base 6, for driving the first clamping assembly 1 to move along a first direction or a third direction.

[0044] In this way, while adjusting the position of the second clamping component 2, the position of the first clamping component 1 can also be adjusted, so as to further facilitate the first clamping component 1 and the second clamping component 2 to fix different types of parts.

[0045] In some embodiments, such as Figure 1 , Figure 2As shown, the flexible clamp 10 also includes a second moving member 5, which is connected between the base 6 and the limiting component 3. The second moving member 5 can drive the limiting component 3 to move along a second direction.

[0046] In this way, the second moving part 5 can drive the limiting component 3 to move, thereby clamping the first clamping component 1 and the second clamping component 2 to a suitable position on the component to be fixed.

[0047] For example, when the size of the part to be fixed in the second direction is small, the second moving part 5 can drive the limiting component 3 to move, so that the distance between the limiting component 3 and the first clamping component 1 and the second clamping component 2 in the second direction is set to be small, so that after the part to be fixed and the limiting component 3 come into contact and are positioned, the first clamping component 1 and the second clamping component 2 can clamp the part to be fixed to a position close to the middle in the second direction.

[0048] Similarly, when the size of the part to be fixed in the second direction is large, the second moving part 5 can drive the limiting component 3 to move, so that the distance between the limiting component 3 and the first clamping component 1 and the second clamping component 2 in the second direction is set to be large, so that after the part to be fixed and the limiting component 3 come into contact and are positioned, the first clamping component 1 and the second clamping component 2 can still clamp the part to be fixed to a position close to the middle in the second direction.

[0049] This makes it easy for the flexible clamp 10 to fix different types of parts, and ensures the fixing effect of the flexible clamp 10 on the parts.

[0050] In some embodiments, such as Figure 2 As shown, the second moving component 5 may include a motor 51 and a telescopic rod 52. The motor 51 is fixed to the base 6, and the telescopic rod 52 is slidably connected to the base 6. The motor 51 drives the telescopic rod 52 to extend or retract, thereby moving the limiting component 3. Of course, in some other embodiments, the second moving component 5 may also include a hydraulic rod, etc.

[0051] For example, the telescopic rod 52 may include a rod body and a lead screw assembly, which is driven between the rod body and the output shaft of the motor 51 to convert the rotational motion of the output shaft of the motor 51 into the linear motion of the telescopic rod 52, thereby driving the telescopic rod assembly to move in a fixed direction.

[0052] For example, the lead screw assembly includes a lead screw and a nut. The output shaft of the motor 51 can be coaxially arranged with the lead screw and connected to the lead screw. The nut is fixed to one end of the rod body, and the lead screw is rotatably connected to the other end of the rod body. The rotation of the output shaft of the motor 51 can drive the lead screw to rotate, thereby driving the nut to move relative to the base 6, so as to drive the rod body to extend and retract.

[0053] Alternatively, the output shaft of motor 51 can be parallel to the lead screw, and the output shaft of motor 51 and the lead screw support can be connected by gears, transmission chains, etc., so that motor 51 drives the lead screw to rotate. This allows motor 51 to be moved to a suitable position, facilitating the spatial arrangement of the second moving part 5.

[0054] For example, motor 51 can be a servo motor 51, stepper motor 51, etc.

[0055] The first moving part 41 and the second moving part 42 described below may also include a motor 51 and a telescopic rod 52. The arrangement of the motor 51 and the telescopic rod 52 may be the same as or different from the arrangement of the second moving part 5, so it will not be described in detail here.

[0056] In some embodiments, such as Figure 1 , Figure 2 As shown, the limiting assembly 3 includes a fourth bracket 31 and a limiting member 32. The fourth bracket 31 is connected to the second moving member 5. The limiting member 32 is connected to the side of the fourth bracket 31 near the first clamping assembly 1 in the second direction, and is used to contact the member to be fixed.

[0057] For example, the fourth support 31 may include a support plate, a support column, etc.

[0058] In this way, the limiting member 32 can be supported to a suitable position by the fourth bracket 31, so that the limiting member 32 can contact different types of members to be fixed for positioning.

[0059] In some embodiments, the flexible clamp 10 further includes a fourth moving member connected between the limiting component 3 and the second moving member 5, for driving the limiting component 3 to move in a third direction.

[0060] This also allows the fourth moving part to adjust the distance between the limiting component 3 and the base 6, so that the limiting component 3 can contact different types of parts to be fixed for positioning.

[0061] For example, the limiting member 32 may include a limiting block, a limiting post, etc. The surface of the limiting block facing the first clamping assembly 1 in the second direction may be a curved surface to facilitate line contact or surface contact with the part to be fixed, such as a machine cover, thereby improving the accuracy of the limiting member 32 in positioning the part to be fixed. Of course, the surface of the limiting block facing the first clamping assembly 1 in the second direction may be a flat surface, etc.

[0062] In some embodiments, such as Figure 1 , Figure 3As shown, the first clamping assembly 1 includes a first clamping arm 11, a first driving member 13, and a second clamping arm 12. The first clamping arm 11 is fixed to the base 6. Of course, in some other embodiments, the first clamping assembly 1 may also include clamping claws, etc., to fix the member to be fixed equally.

[0063] The second clamping arm 12 is located on the side of the first clamping arm 11 away from the base 6. The first driving member 13 is connected to the second clamping arm 12 for driving the second clamping arm 12 to move in a third direction.

[0064] In this way, the first driving member 13 can drive the second clamping arm 12 to move closer to the first clamping arm 11, thereby clamping the part to be fixed between the first clamping arm 11 and the second clamping arm 12, and fixing the part to be fixed by the first clamping arm 11 and the second clamping arm 12.

[0065] Meanwhile, with the arrangement of the first clamping arm 11 and the second clamping arm 12, there is a large installation space around the first clamping arm 11 and the second clamping arm 12, which makes it easy to move the part to be fixed to the first clamping assembly 1 so that the first clamping assembly 1 can fix the part to be fixed.

[0066] In some embodiments, such as Figure 1 , Figure 3 As shown, the first clamping assembly 1 further includes a first support member 14 and a first fastener 15. The first support member 14 is located between the first clamping arm 11 and the second clamping arm 12, and is connected to the end of the first clamping arm 11 near the second clamping assembly 2.

[0067] The first fastener 15 is located between the first clamping arm 11 and the second clamping arm 12, and is connected to the end of the second clamping arm 12 near the second clamping assembly 2. The first fastener 15 and the first support member 14 are arranged sequentially along a third direction, and both the first fastener 15 and the first support member 14 are spherical.

[0068] Since the first support member 14 and the first fastener 15 are both located between the first clamping arm 11 and the second clamping arm 12, the part to be fixed can be clamped by the first support member 14 and the first fastener 15 during the process of the first drive member 13 driving the second clamping arm 12 to move closer to the first clamping arm 11.

[0069] Furthermore, compared to the first support member 14 or the first fastener 15 being block-shaped, when both the first support member 14 and the first fastener 15 are spherical, the spherical surface of the spherical structure contacts the part to be fixed. This can prevent the corners of the first support member 14 or the first fastener 15 from rubbing and wearing against the part to be fixed, thereby providing protection for the part to be fixed and extending the service life of the first support member 14 and the first fastener 15.

[0070] Taking the machine cover as an example, when the first clamping component 1 clamps different machine covers, the thickness direction of the contact position between the machine cover and the first support member 14 and the first fastener may be different. If the first support member 14 and the first fastener 15 are support blocks, the first support member 14 and the first fastener 15 may only contact the machine cover through the corner of the support block. This will affect the clamping effect of the first support member 14 and the first fastener 15 on the machine cover and will cause wear on the machine cover, resulting in scratches on the machine cover.

[0071] When the first support member 14 and the first fastener 15 are spherical, the spherical surface of the spherical structure can make point contact with the machine cover in different thickness directions. Compared with the block structure, the spherical surface of the spherical structure is a continuous curved surface, which will not cause wear to the machine cover when in contact with it.

[0072] For example, the first support member 14 can be a complete sphere or a truncated hemisphere. When the first support member 14 is hemispherical, the planar portion of the hemisphere can be connected to the first clamping arm 11, thereby increasing the contact area between the first support member 14 and the first clamping arm 11 and increasing the stability of the connection between the first support member 14 and the first clamping arm 11. Of course, the first fastener 15 can also be a complete sphere or a truncated hemisphere.

[0073] In some embodiments, such as Figure 1 , Figure 3 As shown, the first clamping assembly 1 also includes a first bracket 16, and the first clamping arm 11 and the first driving member 13 are both connected to the first bracket 16. The second clamping arm 12 is connected to the first driving member 13.

[0074] For example, the first drive component 13 can be a cylinder, a hydraulic cylinder, etc.

[0075] For example, the first support 16 may include a support plate, a support column, etc.

[0076] In this way, the first clamping arm 11 and the first driving member 13 can be supported in a suitable position by the first bracket 16. During the processing of the flexible fixture 10, the first driving member 13 and the first clamping arm 11 can be fixed to the first bracket 16 first, and then the first bracket 16 can be fixed to the base 6. This facilitates the assembly of the flexible fixture 10.

[0077] In some embodiments, such as Figure 3 As shown, the first clamping assembly 1 also includes a first contact 17, which is connected to the first bracket 16 and is used to contact the surface of the component to be fixed facing the base 6. This also provides support to the component to be fixed through the first contact 17, ensuring the stability of the component fixed on the flexible clamp 10.

[0078] For example, the first contact 17 can be a rigid support block with a flat surface to support sheet metal parts or other fasteners. The surface of the support block can be curved to fit the surface of the machine cover or other fasteners, thereby improving the support effect of the first contact 17. Alternatively, the first contact 17 can be a rubber pad or the like. The rubber pad can deform to fit the surface of different types of fasteners, which also improves the support effect of the first contact 17.

[0079] For example, the first contact 17 may be connected to one side of the first bracket 16 in the second direction to avoid the first contact 17 affecting the clamping process of the first clamping assembly 1 on the object to be fixed.

[0080] In some embodiments, such as Figure 1 , Figure 4 As shown, the second clamping assembly 2 includes a third clamping arm 21, a second driving member 23, and a fourth clamping arm 22. The third clamping arm 21 is fixed to the base 6. The fourth clamping arm 22 is located on the side of the third clamping arm 21 away from the base 6. The second driving member 23 is connected to the fourth clamping arm 22 and is used to drive the fourth clamping arm 22 to move in a third direction.

[0081] In this way, the second driving member 23 can drive the fourth clamping arm 22 to move closer to the third clamping arm 21, thereby clamping the part to be fixed between the third clamping arm 21 and the fourth clamping arm 22, and fixing the part to be fixed by the third clamping arm 21 and the fourth clamping arm 22.

[0082] Meanwhile, with the third clamping arm 21 and the fourth clamping arm 22, there is a large installation space around the third clamping arm 21 and the fourth clamping arm 22, which makes it easy to move the part to be fixed to the second clamping assembly 2 so that the second clamping assembly 2 can fix the part to be fixed.

[0083] In some embodiments, such as Figure 1 , Figure 4 As shown, the second clamping assembly 2 further includes a second support member 24 and a second fastener 25. The second support member 24 is located between the third clamping arm 21 and the fourth clamping arm 22, and is connected to the end of the third clamping arm 21 near the second clamping assembly 2. The second fastener 25 is located between the third clamping arm 21 and the fourth clamping arm 22, and is connected to the end of the fourth clamping arm 22 near the second clamping assembly 2. The second fastener 25 and the second support member 24 are arranged sequentially along a third direction, and both the second fastener 25 and the second support member 24 are spherical.

[0084] Since the second support member 24 and the second fastener 25 are both located between the third clamping arm 21 and the fourth clamping arm 22, the part to be fixed can be clamped by the second support member 24 and the second fastener 25 during the process of the second drive member 23 driving the fourth clamping arm 22 to move closer to the third clamping arm 21.

[0085] Furthermore, compared to the second support member 24 or the second fastener 25 being block-shaped, when both the second support member 24 and the second fastener 25 are spherical, the spherical surface of the spherical structure contacts the part to be fixed. This can prevent the corners of the second support member 24 or the second fastener 25 from rubbing and wearing against the part to be fixed, thereby protecting the part to be fixed and extending the service life of the second support member 24 and the second fastener 25.

[0086] For example, the second support member 24 can be a complete sphere or a truncated hemisphere, etc. The second fastener 25 can also be a complete sphere or a truncated hemisphere, etc.

[0087] In some embodiments, such as Figure 1 , Figure 4 As shown, the second clamping assembly 2 also includes a second bracket 26, and the third clamping arm 21 and the second drive member 23 are both connected to the second bracket 26. The fourth clamping arm 22 is connected to the second drive member 23.

[0088] For example, the second drive component 23 can be a cylinder, a hydraulic cylinder, etc.

[0089] For example, the second support 26 may include a support plate, a support column, etc.

[0090] In this way, the third clamping arm 21 and the second driving member 23 can be supported in a suitable position by the second bracket 26. During the processing of the flexible fixture 10, the second driving member 23 and the third clamping arm 21 can be fixed to the second bracket 26 first, and then the second bracket 26 can be fixed to the first moving member 4. This facilitates the assembly of the flexible fixture 10.

[0091] In some embodiments, the second clamping assembly 2 further includes a second contact member connected to the second bracket 26 for contacting the surface of the component to be fixed facing the base 6. This also allows the second contact member to provide support to the component to be fixed, ensuring the stability of the component fixed on the flexible clamp 10.

[0092] For example, the second contact can be a rigid support block, the surface of which can be a plane, an arc surface, etc. Alternatively, the second contact can be a rubber pad, which can undergo a certain deformation to fit with the surface of different types of parts to be fixed.

[0093] For example, the second contact can be connected to one side of the second bracket 26 in the second direction to avoid the second contact affecting the clamping process of the second clamping assembly 2 on the object to be fixed.

[0094] In some embodiments, such as Figure 1 As shown, there are two of each of the first clamping component 1, the second clamping component 2, and the limiting component 3. Along the second direction, the two first clamping components 1, the two second clamping components 2, and the two limiting components 3 are symmetrically arranged about the same plane.

[0095] Compared to a single clamping component 1, a single clamping component 2, and a single limiting component 3, when there are two clamping components 1, two clamping components 2, and two limiting components 3, the two clamping components 1 and the two clamping components 2 can simultaneously clamp the component to be fixed, thereby providing more stable support for the component to be fixed and improving the fixing effect of the flexible clamp 10 on the component to be fixed.

[0096] The two limiting components 3 can simultaneously position the part to be fixed from both sides in the second direction, which can further improve the positioning accuracy of the flexible clamp 10 when fixing the part to be fixed.

[0097] In some other embodiments, the number of the first clamping component 1 and the second clamping component 2 may also be three, four, etc., which can further improve the fixing effect of the flexible clamp 10 on the fixed part.

[0098] The number of limiting components 3 can also be three, four, etc. Multiple limiting components 3 are disposed on opposite sides of multiple first clamping components 1 and multiple second clamping components 2 in the second direction.

[0099] In some embodiments, such as Figure 1 , Figure 4 As shown, the first moving member 4 includes a first moving part 41 and a second moving part 42. The first moving part 41 is connected to the second clamping assembly 2 and is used to drive the second clamping assembly 2 to move along a third direction. The second moving part 42 is connected between the first moving part 41 and the base 6, and the second moving part 42 can drive the first moving part 41 and the second clamping assembly 2 to move along a first direction.

[0100] In this way, the second clamping assembly 2 can be moved along the three directions and the first direction by the first moving part 41 and the second moving part 42 respectively. Compared with the first moving part 4, which includes a robotic arm, the first moving part 41 and the second moving part 42 only need to move the second clamping assembly 2 along a fixed direction. This simplifies the structure of the first moving part 4, facilitates the processing and installation of the first moving part 4, and reduces the processing cost of the flexible fixture 10.

[0101] In some embodiments, such as Figure 1, Figure 4 As shown, the first movable component 4 also includes a third bracket 43. The first movable part 41 is connected to the third bracket 43, and the second movable part 42 is connected between the third bracket 43 and the base 6. Compared with the first movable part 41 being directly connected to the second movable part 42, the third bracket 43 provides a larger installation space, which facilitates the connection between the first movable part 41 and the second movable part 42.

[0102] In some embodiments, such as Figure 1 , Figure 4 As shown, there are two second clamping components 2. When the two second clamping components 2 are symmetrically arranged along the second direction, the corresponding number of first moving parts 4 can also be two, with each of the two first moving parts 4 corresponding one-to-one with the two second clamping components 2. The two first moving parts 4 are symmetrically arranged along the second direction.

[0103] In this way, the two first moving parts 4 can drive the two second clamping components 2 to move respectively, so as to adjust the position of the two second clamping components 2 and ensure that both second clamping components 2 can be connected to different types of objects to be fixed, thereby ensuring the fixing effect of the flexible clamp 10 on different types of objects to be fixed.

[0104] In some embodiments, such as Figure 1 , Figure 4 As shown, the second moving part 42 includes telescopic members 421, and the distance between the ends of the two telescopic members 421 away from the first clamping assembly 1 is greater than the distance between the ends of the two telescopic members 421 close to the first clamping assembly 1.

[0105] For example, the telescopic component 421 can be the telescopic rod 52 mentioned above, or it can be a hydraulic rod or other structures.

[0106] With the above configuration, as the two second moving parts 42 drive the two second clamping components 2 to move toward the two first clamping components 1, the distance between the two second clamping components 2 will gradually decrease.

[0107] When the size of the part to be fixed is small, and the distance between the two second clamping components 2 and the two first clamping components 1 is set small along the first direction, the distance between the two second clamping components 2 is also small. This ensures that both second clamping components 2 can clamp onto the part to be fixed, thus ensuring the fixing effect of the two second clamping components 2 on the part to be fixed.

[0108] When the size of the part to be fixed is large, and the distance between the two second clamping components 2 and the two first clamping components 1 is set large along the first direction, the distance between the two second clamping components 2 is also large. This can ensure that the two second clamping components 2 have sufficient spacing in the second direction, and avoid the position of the two second clamping components 2 clamping the part to be fixed being too concentrated, thereby preventing the part to be fixed from flipping over, so as to ensure the fixing effect of the two second clamping components 2 on the part to be fixed.

[0109] In this way, the two second clamping components 2 can fix different types of parts well, thereby improving the fixing effect of the flexible clamp 10 on different types of parts.

[0110] In some embodiments, such as Figure 1 , Figure 3 As shown, when there are two first clamping components 1, the first clamping arm 11 and the second clamping arm 12 located on the same first clamping component 1 extend in the same direction, and the distance between the ends of the two first clamping arms 11 away from the second clamping component 2 is greater than the distance between the ends of the two first clamping arms 11 close to the second clamping component 2.

[0111] This allows the gap between the first clamping arm 11 and the second clamping arm 12 to extend towards the geometric center of the part to be fixed, pointing from the geometric center of the part to be fixed toward the first clamping assembly 1. The gap between the first clamping arm 11 and the second clamping arm 12 can extend a longer distance, so that the first clamping assembly 1 can be fixed to the part to be fixed, preventing the first clamping assembly 1 and the part to be fixed from bumping or wearing each other.

[0112] In some embodiments, such as Figure 1 , Figure 2 As shown, there are two second moving parts 5, one of which is connected between the base 6 and the limiting component 3. The second moving part 5 can drive the corresponding limiting component 3 to move along the second direction.

[0113] In this way, the two second moving parts 5 can drive the two limiting components 3 to move respectively, so as to adjust the position of the two limiting components 3 at the same time. This ensures that when the two limiting components 3 are in contact with and positioned with different types of parts to be fixed, the first clamping component 1 and the second clamping component 2 can clamp the parts to be fixed to a position close to the middle in the second direction, thus preventing the parts to be fixed from flipping on one side in the second direction and further improving the fixing effect of the flexible clamp 10 on different types of parts to be fixed.

[0114] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
