Description

Technical Field

[0001] This application relates to the field of automated machine tool clamping technology, and in particular to an anti-slip and anti-scratching clamp and an automated clamping device. Background Technology

[0002] In the field of automated machine tool processing, automated loading and unloading robots are widely used for workpiece handling, positioning, and clamping to reduce manual intervention, lower labor intensity, and improve production efficiency. However, when clamping workpieces, traditional fixtures can cause scratches on the workpiece surface due to rigid contact or improper clamping force control, or even cause workpiece displacement or drop due to vibration or inertia, thus affecting machining accuracy and production safety.

[0003] Currently, common clamps are mainly pneumatically or electrically driven, using rigid jaws or vacuum suction cups to fix workpieces. While rigid jaws are simple in structure and have strong clamping force, direct contact with the workpiece leaves indentations or scratches on the surface, significantly impacting workpieces with high surface quality requirements. Vacuum suction cups, although avoiding mechanical contact damage, require a high degree of workpiece surface flatness and cleanliness, and there is still a risk of workpiece falling in the event of a sudden air supply interruption or the presence of oil on the surface. Furthermore, some clamps improve clamping effectiveness by adding textured surfaces or cushioning structures, but it is still difficult to simultaneously meet the dual requirements of scratch and slip resistance. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide an anti-slip and anti-scratching clamp and an automated clamping device that can stably hold workpieces and avoid damage to the workpiece surface.

[0005] The objective of this application is achieved through the following technical solution:

[0006] An anti-slip and anti-scratch clamp, comprising:

[0007] An interface connector for connecting the end effector of a robotic arm;

[0008] Mounting plate, which is fixedly connected to the interface seat;

[0009] A clamping assembly includes a drive unit and two clamping arms. The drive unit is mounted on the mounting plate, and the two clamping arms are symmetrically arranged at the output end of the drive unit. Each clamping arm has a soft rubber block at its end.

[0010] In one embodiment, the clamping assembly further includes a connector, the soft rubber block has a through hole, and the end of the clamping arm has a corresponding connecting hole. The connector passes through the through hole and is inserted into the connecting hole so that the soft rubber block and the clamping arm are detachably connected.

[0011] In one embodiment, the number of the connector, the through hole, and the connecting hole is three, and the three through holes are equidistantly arranged along the edge of the soft rubber block clamping side.

[0013] In one embodiment, the clamping assembly further includes a hard plastic block disposed at the end of the clamping arm, and a soft plastic block covering the side of the hard plastic block facing the inside of the clamping assembly.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0026] Please see Figures 1 to 2 This is an embodiment of the anti-slip and anti-scratch clamp 10, which includes an interface seat 100, a mounting plate 200, and a clamping assembly 300. The interface seat 100 is used to connect the end effector of the robotic arm. The mounting plate 200 is fixedly connected to the interface seat 100. The clamping assembly 300 includes a drive member 310 and two clamping arms 320. The drive member 310 is mounted on the mounting plate 200, and the two clamping arms 320 are symmetrically arranged at the output end of the drive member 310. Each clamping arm 320 has a soft rubber block 330 at its end. The shape of the soft rubber block 330 is adapted to the clamping arm 320, and the soft rubber block 330 is detachably connected to the clamping arm 320.

[0027] In this embodiment, the soft rubber block 330 is a rubber block made of gluten. The anti-slip and anti-scratch clamp 10 uses the rubber block 330 at the end of the clamping arm 320. When clamping the workpiece, the rubber block 330 is in direct contact with the workpiece, avoiding indentations or scratches on the workpiece surface. During the clamping process, the clamping fixture presses the workpiece firmly to prevent it from falling. At the same time, the two clamping arms 320 are arranged opposite each other to adapt to various workpieces and working conditions, with low requirements for workpiece surface quality.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the clamping assembly 300 further includes a connector 340. The soft rubber block 330 has a through hole 3301, and the end of the clamping arm 320 has a corresponding connecting hole (not shown). The connector 340 passes through the through hole 3301 and is inserted into the connecting hole, so that the soft rubber block 330 and the clamping arm 320 are detachably connected. It can be understood that hiding the connector 340 at the bottom of the soft rubber block 330 increases the stability of the overall connection and avoids the opening on the clamping side affecting the stability of the clamping. At the same time, it avoids the soft rubber block 330 squeezing the connector 340 into contact with the workpiece during the clamping process, ensuring the surface quality of the workpiece.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, there are three connectors 340, through holes 3301, and connecting holes. The three through holes 3301 are equidistantly arranged along the edge of the clamping side of the soft rubber block 330. In this embodiment, the three through holes 3301 are equidistantly distributed along the clamping edge of the soft rubber block 330, respectively located within the three clamping surfaces in contact with the workpiece, forming a stable three-point clamping structure. This ensures both the flexible clamping characteristics of the soft rubber block 330 and achieves positioning through a rigid connection, while also facilitating disassembly and maintenance.

[0030] like Figure 2 As shown, in one embodiment, the soft rubber block 330 has an anti-slip and wear-resistant layer 331 on the side facing the inside of the clamping assembly 300. It is understood that during clamping, the workpiece directly contacts the anti-slip and wear-resistant layer 331, enhancing the anti-slip performance of the soft rubber block 330 and thus improving the clamping stability of the clamping assembly 300. Simultaneously, the improved wear resistance extends the service life of the soft rubber block 330.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the clamping assembly 300 further includes a hard plastic block (not shown), which is disposed at the end of the clamping arm 320, and a soft plastic block 330 covers the side of the hard plastic block facing the inside of the clamping assembly 300. In this embodiment, by providing the hard plastic block, rigid support is increased, preventing the soft plastic block 330 from being squeezed and deformed, thus ensuring the stability of clamping and connection.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, there are two clamping components 300 and two mounting plates 200. The two mounting plates 200 are located on both sides of the interface seat 100 and are perpendicular to each other. Each mounting plate 200 is correspondingly provided with a clamping component 300. The two sets of clamping components 300 respectively realize the clamping and unloading of the workpiece. After unloading, the clamped workpiece can be clamped without transfer, simplifying the processing steps and improving production efficiency. Furthermore, in this embodiment, the two sets of clamping components 300 are arranged perpendicular to each other, which can avoid mutual interference when the two sets of clamping components 300 are opened and closed.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a reinforcing rib 210 is provided on one side of the mounting plate 200, and the reinforcing rib 210 is connected to both the mounting plate 200 and the interface seat 100. It can be understood that by providing the reinforcing rib 210, the stability of the mounting plate 200 is enhanced, preventing the clamping assembly 300 from shaking during use, thereby preventing the workpiece from falling or being scratched.

[0034] An automated clamping device includes a robotic arm, a controller, and an anti-slip and anti-scratching clamp 10 as described in any of the above embodiments. The anti-slip and anti-scratching clamp 10 is detachably connected to the end effector of the robotic arm via an interface seat 100. The control terminal of the controller is electrically connected to the control terminal of the robotic arm and the control terminal of the anti-slip and anti-scratching clamp 10, respectively.

[0035] In this embodiment, a robotic arm is installed on one side of the processing equipment. A controller controls the robotic arm and the anti-slip and anti-scratching clamp 10 to automate workpiece clamping, movement, clamping, and unloading, reducing manual intervention, lowering labor intensity, and improving production efficiency. Simultaneously, the anti-slip and anti-scratching clamp 10, with its relatively positioned clamping arms 320, grips the workpiece, adapting to various workpieces and working conditions, thereby enhancing the adaptability of the automated clamping device. Furthermore, during the clamping and pressing process, the anti-slip and anti-scratching clamp 10 prevents indentations or scratches on the workpiece surface, ensuring clamping stability while maintaining the workpiece's surface quality.

[0036] Compared with the prior art, this application has at least the following advantages:

[0037] The aforementioned anti-slip and anti-scratch clamps incorporate soft rubber blocks at the ends of the clamping arms. These blocks directly contact the workpiece during clamping, preventing indentations or scratches on the workpiece surface. During clamping, the clamps hold the workpiece firmly, preventing it from falling. Furthermore, the two clamping arms are positioned opposite each other, adapting to various workpieces and working conditions, and have low requirements for workpiece surface quality.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
