Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, specifically relating to a clamping device that is adaptable to workpieces of various specifications. Background Technology

[0002] In modern manufacturing, efficient and precise transfer of workpieces from their placement position to the processing position is crucial for ensuring a smooth production process. Current technologies often use clamping devices designed for workpieces of a single specification, meaning that each workpiece of different size or shape requires a specific clamping device for adaptation. This one-to-one design reveals significant limitations when the production line needs to handle workpieces with varying degrees of curvature.

[0003] Whenever the curvature of the workpiece changes, the corresponding clamping device must be replaced. This not only wastes valuable time and reduces overall work efficiency, but also increases the cost of equipment maintenance and management. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: to propose a clamping device that can adapt to workpieces of multiple specifications. By rotating the rotating base relative to the support base, the clamping angle of the clamping member can be adjusted, and by adjusting the position of the connecting rod on the rotating base, the clamping member can be accurately positioned to the clamping position. Thus, the clamping device in this solution only needs to make appropriate parameter adjustments to the existing clamping member to adapt to different curvatures of the workpiece.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a clamping device that is adaptable to workpieces of multiple specifications, including...

[0006] Fixed bracket;

[0007] A clamping assembly is provided on the fixed bracket, with at least two clamping assemblies spaced apart on the fixed bracket. Each clamping assembly includes a support base, a rotating base, a connecting rod, and a clamping member. The support base is fixed on the fixed bracket, and the rotating base is connected to the support base and is rotatable relative to the support base. The connecting rod passes through the rotating base, and one end of the connecting rod is connected to the clamping member. The clamping member is used to clamp a workpiece.

[0008] The clamping member can be driven to rotate synchronously due to the rotation of the rotating base relative to the support base, and can be driven to move relative to the rotating base by adjusting the position of the connecting rod on the rotating base.

[0009] In the aforementioned clamping device for adapting to workpieces of various specifications, the support base is provided with an arc-shaped through hole, and the rotating base is provided with a threaded hole. One end of the first bolt passes through the arc-shaped through hole and is threaded onto the threaded hole for connecting the rotating base to the support base.

[0010] In the aforementioned clamping device for adapting to workpieces of multiple specifications, the support base is further provided with a first through hole, and the rotating base is provided with a corresponding receiving hole. One end of the pin passes through the first through hole and is inserted into the receiving hole. The rotating base can rotate around the pin because it rotates relative to the support base.

[0011] In the aforementioned clamping device for adapting to workpieces of various specifications, a fixing block is also provided on the rotating base. The fixing block is provided with a second through hole. One end of the second bolt passes through the second through hole and is threaded to the end of the connecting rod away from the clamping member. The connecting rod can be moved relative to the rotating base by adjusting the depth of the second bolt connected to the connecting rod, thereby adjusting the position of the connecting rod on the rotating base.

[0012] In the aforementioned clamping device for adapting to workpieces of various specifications, the clamping assembly further includes a support member, which is hinged to the clamping member.

[0013] In the aforementioned clamping device for adapting to workpieces of multiple specifications, the clamping assembly further includes a driving member disposed on the clamping member, and the support member is connected to the output end of the driving member, the driving member being used to drive the support member to rotate.

[0014] In the aforementioned clamping device for adapting to workpieces of multiple specifications, the clamping member is provided with a clamping part, the support member is provided with a support part disposed opposite to the clamping part, and the workpiece is fixed between the clamping part and the support part.

[0015] In the aforementioned clamping device for adapting to workpieces of various specifications, a first detection element is also provided on the side of the clamping member to detect whether the workpiece has shifted.

[0016] In the aforementioned clamping device for adapting to workpieces of multiple specifications, a connecting block is connected to the side of the clamping member, and the first detection member is connected to the connecting block. The connecting block is used to allow the first detection member to be connected to the clamping member.

[0017] In the aforementioned clamping device for adapting to workpieces of various specifications, a second detection element is further provided on the clamping member, which is located on the side of the clamping member and is used to detect whether the workpiece is clamped by the clamping member.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) By rotating the rotating base relative to the support base, the clamping angle of the clamping component is adjusted, and by adjusting the position of the connecting rod on the rotating base, the clamping component can be accurately positioned to the clamping position. This allows the clamping device in this solution to adapt to different curvatures of the workpiece by only making appropriate parameter adjustments to the existing clamping component. This not only significantly improves work efficiency, but also greatly reduces the maintenance and management costs caused by frequent equipment replacement.

[0020] (2) The clamping part is equipped with a special clamping part, and the support block is equipped with a corresponding support part. These two parts work together to ensure that the workpiece is firmly fixed.

[0021] (3) The first detection element is used to monitor the position change of the workpiece in real time to detect whether the workpiece has moved and to feed the data back to the system so that the clamping force can be further adjusted based on the data to ensure that the workpiece is firmly clamped; the second detection element is used to confirm whether the clamping work is completed and to verify the clamping status by detecting the presence of the workpiece; this design not only improves the clamping accuracy, but also enhances the automation and safety of the system.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] like Figure 1 As shown in the figure, this solution is mainly for a clamping device that can be adapted to workpieces of various specifications for use in automotive trim processing.

[0030] like Figures 1 to 4 As shown, this solution provides a clamping device adaptable to workpieces of various specifications, comprising: a fixed bracket 1; and clamping components 2. The fixed bracket 1 has at least two clamping components 2, which are spaced apart on the fixed bracket 1. Each clamping component 2 includes a support base 3, a rotating base 4, a connecting rod 5, and a clamping member 6. The support base 3 is fixed on the fixed bracket 1, and the rotating base 4 is connected to the support base 3 and can rotate relative to the support base 3. The connecting rod 5 passes through the rotating base 4, and one end of the connecting rod 5 is connected to the clamping member 6. The clamping member 6 is used to clamp the workpiece. The clamping member 6 can be driven to rotate synchronously due to the rotation of the rotating base 4 relative to the support base 3, and can be driven to move relative to the rotating base 4 by adjusting the position of the connecting rod 5 on the rotating base 4.

[0031] Before the clamping device in this solution starts working, the operator can flexibly adjust it according to the specific dimensions of the workpiece to be processed. Specifically, by rotating the base 4 relative to the support 3, the angle position of the clamping element 6 can be precisely adjusted. By adjusting the position of the connecting rod 5 on the base 4, the clamping element 6 can be moved closer to or away from the base 4. This design not only allows the operator to adjust the angle of the clamping element 6 according to the curvature of the workpiece, but also ensures that the clamping element 6 can be accurately positioned to clamp the workpiece. This maintains the optimal clamping angle while ensuring that the clamping element 6 correctly contacts and firmly grips the workpiece, avoiding clamping failure or workpiece damage due to improper distance. This design not only greatly expands the application range of the clamping device in this solution, but also greatly simplifies the operation process. Whether it is a slight adjustment or a large change, the operator can respond quickly and adjust the clamping device to the most suitable state. Compared with replacing the entire clamping device, this solution only requires appropriate parameter adjustments to the existing clamping element 6. This not only significantly improves work efficiency, but also greatly reduces the maintenance and management costs caused by frequent equipment replacement.

[0032] Furthermore, the support base 3 is provided with an arc-shaped through hole 7, and the rotating base 4 is provided with a threaded hole 8. One end of the first bolt passes through the arc-shaped through hole 7 and is threaded into the threaded hole 8 for connecting the rotating base 4 and the support base 3.

[0033] Furthermore, the support base 3 is provided with a first through hole 9, and the rotating base 4 is provided with a corresponding receiving hole 10. One end of the pin passes through the first through hole 9 and is connected to the receiving hole 10. The pin acts as a rotating shaft here, allowing the rotating base 4 to rotate relative to the support base 3. This design ensures that the rotating base 4 can rotate freely within a certain range while maintaining a stable connection with the support base 3.

[0034] The rotating base 4 is connected to the support base 3 by the first bolt and the pin. When it is necessary to adjust the angle of the clamping part 6, first loosen the connection between the first bolt and the threaded hole 8. At this time, the rotating base 4 can rotate freely relative to the support base 3 around the pin. During the process of manually rotating the rotating base 4, the first bolt will slide along the arc-shaped through hole 7 on the support base 3 with the rotating base 4. When the rotating base 4 is adjusted to the required angle, tighten the connection between the first bolt and the threaded hole 8 so that it passes through the arc-shaped through hole 7 and is firmly fixed in the threaded hole 8, thereby locking the rotating base 4 in the new position and completing the adjustment of the angle of the clamping part 6.

[0035] Furthermore, a fixing block 11 is also provided on the rotating base 4. The fixing block 11 has a second through hole 12. One end of the second bolt passes through the second through hole 12 and is threaded to the end of the connecting rod 5 away from the clamping member 6. After the angle of the clamping member 6 is adjusted, the position of the connecting rod 5 on the rotating base 4 can be adjusted by rotating the second bolt, thereby adjusting the distance between the clamping member 6 and the rotating base 4. Specifically, by rotating the second bolt, the depth to which it is screwed into the connecting rod 5 can be changed, thereby driving the connecting rod 5 to move relative to the rotating base 4, so that the clamping member 6 reaches a position suitable for clamping the workpiece. This design ensures that the clamping member 6 can accurately position itself to the most suitable position for gripping the workpiece while maintaining the best angle.

[0036] Furthermore, the clamping assembly 2 also includes a support 13, which is hinged to the clamping assembly 6 to provide support for the workpiece.

[0037] Furthermore, the clamping assembly 2 also includes a drive member 14, which is disposed on the clamping member 6. The support member 13 is connected to the output end of the drive member 14. The drive member 14 is used to drive the support member 13 to rotate. The drive member 14 can be a motor, a hydraulic cylinder, or a pneumatic cylinder.

[0038] Before the clamping device of this scheme starts working, when the clamping member 6 is adjusted according to the curvature of the workpiece, the support member 13 is hinged to the clamping member 6, and the support member 13 and the clamping member 6 move synchronously. When the clamping member 6 clamps the workpiece, the workpiece is located between the clamping member 6 and the support member 13. The driving member 14 is used to drive the support member 13 to rotate relative to the clamping member 6. Before preparing to clamp the workpiece, the driving member 14 starts, driving the support member 13 to rotate away from the clamping member 6, so as to make room for clamping the workpiece. After the clamping member 6 and the support member 13 are in place, the driving member 14 starts again, driving the support member 13 to rotate towards the clamping member 6, until the support member 13 and the clamping member 6 work together to stably clamp the workpiece. When it is necessary to release the workpiece, the driving member 14 starts in the opposite direction, driving the support member 13 away from the clamping member 6, and releasing the workpiece. This design allows the clamping device to flexibly adapt to workpieces with different curvatures, while ensuring the stability of the workpiece during the transfer process.

[0039] Furthermore, the clamping member 6 is provided with a dedicated clamping part 15, which is designed to directly contact and firmly clamp the workpiece. Correspondingly, the support member 13 is provided with a support part 16 corresponding to the clamping part 15. The two parts work together to ensure that the workpiece can be firmly fixed between the clamping part 15 and the support part 16.

[0040] To detect whether the workpiece shifts during clamping, a first detection element 17 is provided on the side of the clamping member 6. When at least two sets of clamping components 2 clamp the workpiece together, due to the curvature and elasticity of the workpiece itself, if the clamping force is inappropriate, the workpiece may shift. In this case, the first detection element 17 can monitor the position change of the workpiece in real time. Specifically, during the clamping process of the clamping member 6 and the support member 13, the first detection element 17 monitors the position change of the workpiece at the clamping point to determine whether the workpiece has shifted. Once shifting is detected, the system can further adjust the clamping force according to the data provided by the first detection element 17 to ensure that the workpiece is firmly clamped. The first detection element 17 is preferably an encoder, which is a device that converts angular displacement or linear displacement into electrical signals.

[0041] In order to allow the first detection element 17 to be connected to the clamping member 6, a connecting block 18 is connected to the side of the clamping member 6, and the first detection element 17 is connected to the connecting block 18.

[0042] In order to detect whether the clamping member 6 is clamping the workpiece, a second detection member 19 is also provided on the side of the clamping member 6. The second detection member 19 is preferably a displacement sensor, which confirms whether the clamping work is completed by detecting the presence of the workpiece.
