Description

Technical Field

[0001] This utility model relates to the field of automotive parts clamping technology, and in particular to a mechanical clamping device. Background Technology

[0002] In automated production lines for automobile manufacturing and parts processing, mechanical clamping equipment is widely used in processes such as parts handling and loading / unloading. For large plate-shaped parts, such as car doors, side panels, and front floor panels, which are large in size and irregular in shape, existing clamping mechanisms mostly adopt a single vertical clamping method, which is not very adaptable to parts with complex curved surfaces or parts that need to be clamped at specific angles. Utility Model Content

[0003] Therefore, there is a need to provide a mechanical clamping device to solve the technical problem that existing clamping mechanisms mostly adopt a single vertical clamping method, which is not very adaptable to parts with complex curved surfaces or parts that need to be clamped at specific angles.

[0004] To achieve the above objectives, this utility model provides a mechanical clamping device, comprising:

[0005] Clamping seat;

[0006] A clamping mechanism is mounted on a clamping base. The clamping mechanism includes two or more clamping components. Each clamping component includes a clamping connecting plate, a clamping drive unit, a first clamping member, and a second clamping member. The clamping connecting plate is fixedly connected to the clamping base. The clamping drive unit is mounted on one end of the clamping connecting plate near the clamping base. The first clamping member is mounted on the other end of the clamping connecting plate. The second clamping member is hinged to the output end of the clamping drive unit and is located below the first clamping member. The clamping drive unit drives the second clamping member to rotate around the hinge point with the output end of the clamping drive unit so that the second clamping member cooperates with the first clamping member to clamp the part.

[0007] Unlike existing technologies, the technical solution of this application transforms traditional linear vertical clamping into rotary clamping by setting up two or more clamping components and using a hinged design between the output end of the clamping drive unit and the second clamping member. This allows the second clamping member to adaptively adjust its angle when contacting the part, thereby forming surface or line contact with the surface of parts with complex curved surfaces or requiring tilted clamping, rather than the point contact or poor contact that may occur with traditional vertical clamping. This greatly improves the adaptability and clamping fit of the clamping mechanism for non-planar and irregularly shaped parts, enabling the clamping mechanism to better adapt to different parts.

[0008] In one embodiment of the present invention, the first clamping member includes a first clamping block, which is installed at the bottom of the other end of the clamping connecting plate. The second clamping member includes a second clamping block and a clamping transition frame, and the second clamping block is hinged to the output end of the clamping drive unit through the clamping transition frame.

[0009] Thus, by employing specific designs for the first and second clamping blocks, and introducing a clamping transition frame to connect the drive unit and the second clamping block, this structure transforms the linear or rotary output of the drive unit into a stable rotary clamping motion of the second clamping block. This design increases the contact area between the clamping components and the parts, disperses the clamping pressure, avoids indentation damage to the surface of the parts, and ensures the reliability of power transmission.

[0010] As one embodiment of this utility model, the clamping transition frame includes a fixed block and two spaced connecting brackets mounted on the fixed block. The fixed block is connected to the second clamping block, and the gap between the two connecting brackets allows the output end of the clamping drive unit to be inserted and hinged to the output end of the clamping drive unit.

[0011] Thus, the clamping transition frame adopts a double-connecting bracket design with gaps, providing a stable insertion and hinge space for the output end of the drive unit. This symmetrical structure ensures that the second clamping component is subjected to balanced forces during rotation, effectively preventing jamming or uneven wear caused by unilateral forces, and ensuring smooth and precise clamping action.

[0012] In one embodiment of this utility model, the second clamping member further includes a V-shaped adapter block, and the fixing block is connected to the second clamping block through the V-shaped adapter block.

[0013] Thus, by adding a V-shaped adapter block to connect the fixing block and the second clamping block, this design provides additional angle adjustment and space clearance. It allows the final working posture of the second clamping block to be optimized according to the specific shape of the part, enhancing the clamping system's adaptability to parts with complex curved surfaces.

[0014] As one embodiment of the present invention, the clamping assembly further includes a positioning connecting plate and a first positioning pin. The positioning connecting plate is installed at the other end of the clamping connecting plate, and the first positioning pin is installed on the positioning connecting plate. The first positioning pin is used to cooperate with the positioning hole on the part.

[0015] In this way, before the clamping action occurs, the positioning pin is first used to accurately position the part by engaging with the hole on the part, and then the part is clamped. This ensures that the position of the same type of part relative to the mechanical clamping device is highly consistent each time it is clamped, which greatly improves the repeatability of the positioning accuracy of the loading.

[0016] As one embodiment of this utility model, the clamping assembly further includes a sensor connecting plate and a first position sensor. The sensor connecting plate is installed at the other end of the clamping connecting plate, and the first position sensor is installed on the sensor connecting plate with its detection end facing downward, for detecting that the part is placed in the correct position.

[0017] Thus, by setting up a sensor connection plate and a first position sensor, it is possible to detect in real time whether the part has been correctly placed in the clamping position. The sensor signal can serve as an interlock condition for the operation of the clamping drive unit, avoiding malfunctions of the mechanical clamping device when there is no clamping or the clamping fails, thereby improving the intelligence and reliability of the entire automation system.

[0018] As one embodiment of this utility model, the clamping mechanism further includes a positioning component, which includes a mounting base, a second positioning pin, and a second position sensor. The mounting base is mounted on the clamping base, and the second positioning pin and the second position sensor are mounted on the mounting base. The second positioning pin is used to cooperate with the positioning hole on the part, and the detection end of the second position sensor is set downward to detect that the part is placed in place.

[0019] Thus, by adding an independent positioning component, the global precision positioning of the clamping mechanism is improved.

[0020] As one embodiment of this utility model, the clamping assembly is provided with six sets, with three sets of clamping assemblies installed at the front end and the rear end of the clamping seat, and the three sets of clamping assemblies are respectively located on the left, middle and right sides of the clamping seat.

[0021] Thus, by symmetrically arranging six sets of clamping components at the front and rear ends of the clamping base, the device forms an enveloping clamping layout for large plate-shaped parts. This distribution can rationally distribute the clamping force according to the center of gravity and structural strength of the part, avoiding deformation of the part due to cantilever or uneven force.

[0022] In one embodiment of this utility model, the clamping drive unit in the middle extends vertically, while the clamping drive units on the left and right sides are inclined toward the clamping drive unit in the middle.

[0023] In this way, by setting the clamping drive unit in the middle to be vertical and the clamping drive units on the left and right sides to be tilted inward, the clamping force direction can be better directed towards the structural skeleton of the part, which further improves the clamping stability and can effectively reduce the risk of surface dents of the part caused by improper clamping force.

[0024] In one embodiment of this utility model, the clamping base is a porous frame.

[0025] Thus, by designing the gripper as a porous frame structure, not only is the weight of the mechanical gripping device significantly reduced, facilitating robot or actuator drive, but it also provides extremely high flexibility for the installation of gripping components, positioning components, and other auxiliary elements. The mounting positions of each component on the frame can be quickly adjusted according to the shape and size of different parts, achieving rapid reconfiguration and high adaptability of the mechanical gripping device.

[0026] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0046] For large plate-shaped parts, such as car doors, side panels, and front floor, which are large in size and irregular in shape, existing clamping mechanisms mostly adopt a single vertical clamping method, which is not very adaptable to parts with complex curved surfaces or parts that need to be clamped at a specific angle.

[0047] In view of this, this application provides a mechanical clamping device 100, including a clamping base 1 and a clamping mechanism 2. The clamping mechanism 2 is mounted on the clamping base 1 and includes two or more clamping components 21. Each clamping component 21 includes a clamping connecting plate 211, a clamping drive unit 212, a first clamping member 213, and a second clamping member 214. The clamping connecting plate 211 is fixedly connected to the clamping base 1. The clamping drive unit 212 is mounted on one end of the clamping connecting plate 211 near the clamping base 1. The first clamping member 213 is mounted on the other end of the clamping connecting plate 211. The second clamping member 214 is hinged to the output end of the clamping drive unit 212 and is located below the first clamping member 213. The clamping drive unit 212 drives the second clamping member 214 to rotate around the hinge point with the output end of the clamping drive unit 212 so that the second clamping member 214 cooperates with the first clamping member 213 to clamp the part 200.

[0048] According to some embodiments of this application, please refer to Figures 1 to 6 This embodiment relates to a mechanical clamping device 100, including a clamping base 1 and a clamping mechanism 2. The clamping mechanism 2 is mounted on the clamping base 1 and includes two or more clamping components 21. Each clamping component 21 includes a clamping connecting plate 211, a clamping driving unit 212, a first clamping member 213, and a second clamping member 214. The clamping connecting plate 211 is fixedly connected to the clamping base 1. The clamping driving unit 212 is mounted on one end of the clamping connecting plate 211 near the clamping base 1. The first clamping member 213 is mounted on the other end of the clamping connecting plate 211. The second clamping member 214 is hinged to the output end of the clamping driving unit 212 and is located below the first clamping member 213. The clamping driving unit 212 drives the second clamping member 214 to rotate around the hinge point with the output end of the clamping driving unit 212 so that the second clamping member 214 cooperates with the first clamping member 213 to clamp the part 200.

[0049] The mechanical clamping device 100 also includes an actuator (e.g., a robotic arm), with the clamping seat 1 mounted on the actuator and driven to move by the actuator.

[0050] One end of the clamping connecting plate 211 can be fixedly connected to the clamping seat 1 by bolts. The clamping drive unit 212 can be a cylinder or an electric push rod, with its cylinder body fixed to one end of the clamping connecting plate 211 near the clamping seat 1, and its output end can be hinged to the second clamping member 214 through the output block 215. The first clamping member 213 can be installed on the other end of the clamping connecting plate 211 (i.e., the end away from the clamping seat 1) by bolts.

[0051] Part 200 can be various automotive components. This embodiment uses the clamping of a sunroof as an example. The clamped sunroof is moved to the welding position to weld the nut. When part 200 needs to be clamped, the piston rod of the clamping drive unit 212 extends. Since the second clamping member 214 is hinged to the piston rod, the linear motion of the piston rod drives the second clamping member 214 to rotate upward around the hinge point, thereby cooperating with the fixed first clamping member 213 to clamp part 200 located between them. When releasing, the piston rod retracts, causing the second clamping member 214 to rotate downward and open the clamping opening. This rotational clamping action is more adaptable to the slight contour changes of part 200 than purely vertical clamping.

[0052] The technical solution of this application, by setting two or more sets of clamping components 21 and adopting a hinged design between the output end of the clamping drive unit 212 and the second clamping member 214, transforms the traditional linear vertical clamping into rotary clamping. This allows the second clamping member 214 to adaptively adjust its angle when contacting the part 200, thereby forming surface or line contact with the surface of the part 200 that has complex curved surfaces or requires tilted clamping, rather than the point contact or poor contact that may occur with traditional vertical clamping. This greatly improves the adaptability and clamping fit of the clamping mechanism 2 to non-planar and irregularly shaped parts 200, and the clamping mechanism 2 can better adapt to different parts 200.

[0053] like Figure 3 As shown, the first clamping member 213 includes a first clamping block, which is installed at the bottom of the other end of the clamping connecting plate 211. The second clamping member 214 includes a second clamping block 2141 and a clamping transition frame 2142. The second clamping block 2141 is hinged to the output end of the clamping drive unit 212 through the clamping transition frame 2142.

[0054] Both the first clamping block and the second clamping block 2141 can be L-shaped. Compared with simple rectangular or flat clamping blocks, the vertical and horizontal sides of the L-shape form a reinforcing structure. The applied clamping force can be transmitted and distributed more evenly through this structure.

[0055] Thus, by employing a specific design of the first and second clamping blocks 2141, and introducing a clamping transition frame 2142 to connect the drive unit and the second clamping block 2141, this structure converts the linear or rotary output of the drive unit into a stable rotary clamping motion of the second clamping block 2141. This design increases the contact area between the clamping components and the part 200, disperses the clamping pressure, avoids indentation damage to the surface of the part 200, and ensures the reliability of power transmission.

[0056] like Figure 3As shown, the clamping transition frame 2142 includes a fixing block 2143 and two spaced connecting brackets 2144 mounted on the fixing block 2143. The fixing block 2143 is connected to the second clamping block 2141. The gap between the two connecting brackets 2144 allows the output end of the clamping drive unit 212 to be inserted and is hinged to the output end of the clamping drive unit 212.

[0057] The gap between the two connecting brackets 2144 is just enough for the output block 215 to be inserted, and the connection is achieved by a pin.

[0058] Thus, the clamping transition frame 2142 adopts a double connecting bracket 2144 design with a gap, providing a stable insertion and hinge space for the output end of the drive unit. This symmetrical structure ensures that the second clamping member 214 is subjected to balanced force during rotation, effectively preventing jamming or uneven wear caused by unilateral force, and ensuring smooth and precise clamping action.

[0059] like Figure 4 As shown, the second clamping member 214 also includes a V-shaped adapter block 2145, and the fixing block 2143 is connected to the second clamping block 2141 through the V-shaped adapter block 2145.

[0060] Thus, by adding a V-shaped adapter block 2145 to connect the fixing block 2143 and the second clamping block 2141, this design provides additional angle adjustment and space clearance. It allows the final working posture of the second clamping block 2141 to be optimized according to the specific shape of the part 200, enhancing the adaptability of the clamping system to complex curved surface parts 200.

[0061] like Figure 5 As shown, the clamping assembly 21 also includes a positioning connecting plate 216 and a first positioning pin 217. The positioning connecting plate 216 is installed at the other end of the clamping connecting plate 211, and the first positioning pin 217 is installed on the positioning connecting plate 216. The first positioning pin 217 is used to cooperate with the positioning hole on the part 200.

[0062] The positioning connecting plate 216 is equipped with a vertically downward first positioning pin 217. Before the clamping action begins, the first positioning pin 217 is first inserted into a pre-drilled process hole on the surface of the part 200 to achieve coarse positioning.

[0063] In this way, before the clamping action occurs, the positioning pin is first used to accurately position the part 200 by cooperating with the hole on the part 200, and then the clamping is performed. This ensures that the position of the same part 200 relative to the mechanical clamping device 100 is highly consistent each time it is clamped, which greatly improves the repeatability of the positioning accuracy of the feeding.

[0064] like Figure 5As shown, the clamping assembly 21 also includes a sensor connecting plate 218 and a first position sensor 219. The sensor connecting plate 218 is installed at the other end of the clamping connecting plate 211, and the first position sensor 219 is installed on the sensor connecting plate 218 with the detection end facing downward, for detecting when the part 200 is placed in position.

[0065] A first position sensor 219 (such as a photoelectric sensor or proximity switch) with its detection end facing downwards is mounted on the sensor connection plate 218. It is used to detect whether the part 200 has moved to the correct height position to be clamped.

[0066] Thus, by setting up the sensor connection plate 218 and the first position sensor 219, it is possible to detect in real time whether the part 200 has been correctly placed in the clamping position. The sensor signal can serve as an interlock condition for the operation of the clamping drive unit 212, avoiding maloperation of the mechanical clamping device 100 when there is no clamping or the clamping fails, thereby improving the intelligence and reliability of the entire automation system.

[0067] like Figure 2 and Figure 6 As shown, the clamping mechanism 2 also includes a positioning component 22. The positioning component 22 includes a mounting base 221, a second positioning pin 222, and a second position sensor 223. The mounting base 221 is mounted on the clamping base 1, and the second positioning pin 222 and the second position sensor 223 are mounted on the mounting base 221. The second positioning pin 222 is used to cooperate with the positioning hole on the part 200. The detection end of the second position sensor 223 is set downward to detect that the part 200 is placed in the correct position.

[0068] The second positioning pin 222 is longer and thicker than the first positioning pin 217, and is used to engage with the main positioning hole on the part 200 to achieve precise positioning. Optionally, the first position sensor 219 and the second position sensor 223 are located in different orientations. The second position sensor 223 can confirm that the part 200 has roughly entered the working range, achieving coarse positioning. Subsequently, the first position sensor 219 can precisely detect the positioning of the part 200 in its assigned area. The two work together, not only eliminating blind spots through multi-dimensional sensing from different orientations and effectively identifying abnormal postures such as tilting or warping of the part 200, but more importantly, triggering an alarm and stopping the machine when either position sensor fails to trigger, thereby greatly improving the reliability, safety, and intelligent diagnostic capabilities of the entire clamping process.

[0069] Thus, by adding an independent positioning component 22, the global precision positioning of the clamping mechanism 2 is improved.

[0070] like Figure 2As shown, there are six sets of clamping components 21. Three sets of clamping components 21 are installed at the front end and the rear end of the clamping base 1, respectively. The three sets of clamping components 21 are located on the left, middle and right sides of the clamping base 1.

[0071] Three sets of clamping components 21 are symmetrically arranged at the front and rear ends of the clamping base 1. Thus, by symmetrically arranging six sets of clamping components 21 at the front and rear ends of the clamping base 1, the device forms an enveloping clamping layout for large plate-shaped parts 200. This distribution can rationally distribute the clamping force according to the center of gravity and structural strength of the part 200, preventing deformation of the part 200 due to cantilever or uneven force.

[0072] like Figures 2 to 4 As shown, the clamping drive unit 212 in the middle extends along the vertical direction Y, and the clamping drive units 212 on the left and right sides are inclined toward the clamping drive unit 212 in the middle.

[0073] In this way, by setting the clamping drive unit 212 in the middle to the vertical direction Y, and setting the clamping drive units 212 on the left and right sides to be tilted inward, the clamping force direction can be better directed towards the structural skeleton of the part 200, which further improves the clamping stability and can effectively reduce the risk of the surface of the part 200 being dented due to improper clamping force.

[0074] like Figure 2 As shown, the clamping base 1 is a porous frame.

[0075] The clamping base 1 can be welded from aluminum alloy profiles or steel plates. The clamping base 1 has evenly distributed mounting holes, which facilitate the flexible installation of various components.

[0076] Thus, by designing the clamping base 1 as a porous frame structure, not only is the weight of the entire mechanical clamping device 100 significantly reduced, facilitating robot or actuator drive, but it also provides extremely high flexibility for the installation of the clamping assembly 21, positioning assembly 22, and other auxiliary components. The mounting positions of each component on the frame can be quickly adjusted according to the shape and size of different parts 200, achieving rapid reconfiguration and high adaptability of the mechanical clamping device 100.

[0077] The working principle of the mechanical clamping device 100 is as follows: the actuator moves the clamping mechanism 2 above the part 200. After the second positioning pin 222 and the first positioning pin 217 are inserted into the positioning holes of the part 200 in sequence, the second position sensor 223 and the first position sensor 219 detect the part 200's positioning signal. After the positioning is detected, all clamping drive units 212 are activated, driving the second clamping block 2141 to rotate and clamp the part 200.

[0078] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
