Description

Technical Field

[0001] This utility model relates to the field of processing fixtures, specifically to a rubber-metal integrated molded clamping gripper. Background Technology

[0002] In industrial production, grippers are key components in various automated equipment and processing machinery used for gripping and fixing workpieces. Their performance directly affects production efficiency, product quality, and equipment operational stability. Traditional grippers have revealed many problems in practical applications, urgently requiring innovation and improvement.

[0003] Among the many publicly disclosed patented technologies, some clamping structures use a single metal material to make the clamping components. For example, Chinese patent CN202222818648.2 discloses a rotatable and easily movable metal clamping fixture. During the clamping process, the direct contact between the metal and the workpiece can easily cause scratches, indentations and other damage to the workpiece surface. This is especially true for soft materials such as aluminum, copper, and plastic, or for workpieces with precision surface treatments (such as polishing or plating). Such damage can seriously affect the appearance quality and performance of the product. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a rubber-metal integrated clamping gripper. The tip, arc surface and sides of the metal clamping block are all covered with a rubber layer, which avoids scratches, indentations or rigid collision damage to the workpiece surface caused by the metal clamping block. Furthermore, the first groove on the arc surface of the clamping block and the first locking block of the rubber layer are engaged to ensure a firm connection between the rubber layer and the metal clamping block.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A rubber-metal one-piece molded clamping gripper includes a driving component and a clamping hand. The driving component is used to drive the clamping hand to clamp a workpiece. The clamping hand includes a clamping block and a rubber layer. The clamping block has an arc-shaped surface, a pointed tip, and a side. The two ends of the arc-shaped surface are respectively connected to the pointed tip and the side. One end of the rubber layer covers the surface of the pointed tip and extends into the surface of the arc-shaped surface until it covers the surface of the side. The arc-shaped surface has a plurality of first slots. The inner wall of the rubber layer extends into the first slots to form first locking blocks, which engage with the corresponding first slots.

[0007] Furthermore, a second slot is provided on the side of the tip away from the curved surface, and a second locking block extends from the inner wall of the adhesive layer into the second slot, and the second locking block engages with the second slot.

[0008] Furthermore, a third slot is provided on the surface of the side portion, and a third locking block extends from the inner wall of the adhesive layer into the third slot, the third locking block engaging with the third slot.

[0009] Furthermore, the plurality of the first card slots are spaced apart circumferentially along the arcuate surface.

[0010] Furthermore, the adhesive layer is made of rubber.

[0011] Furthermore, the number of grippers is two, the two grippers are arranged opposite each other, and the two arc-shaped surfaces are respectively arranged on the opposite surfaces of the two grippers.

[0012] Furthermore, the surface of the adhesive layer is provided with multiple anti-slip protrusions.

[0013] Furthermore, the multiple anti-slip protrusions are distributed in a matrix on the adhesive layer located on the curved surface.

[0014] Furthermore, the driving component is a cylinder.

[0015] The beneficial effects of this utility model are as follows: The rubber-metal integrated clamping gripper of this utility model has a simple structure. The tip, arc surface, and sides of the metal clamping block are all covered with a rubber layer. During clamping, the workpiece will not directly contact the high-hardness clamping block, fundamentally avoiding scratches, indentations, or rigid impact damage to the workpiece surface caused by the metal clamping block. Simultaneously, the first groove on the arc surface of the clamping block and the first locking block of the rubber layer ensure a firm connection between the rubber layer and the metal clamping block, enhancing the bonding strength between the rubber and metal and preventing the rubber layer from detaching during repeated clamping and deformation under stress.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figure 1-3 As shown, a rubber-metal one-piece molded clamping gripper includes a driving component 1 and a clamping hand. The driving component 1 is used to drive the clamping hand to clamp a workpiece. The clamping hand includes a clamping block 2 and an adhesive layer 3. The clamping block 2 is made of metal and has an arc-shaped surface 21, a tip 22, and a side 23. The two ends of the arc-shaped surface 21 are connected to the tip 22 and the side 23 in the circumferential direction, respectively. One end of the adhesive layer 3 covers the surface of the tip 22 and extends into the surface of the arc-shaped surface 21 until it covers the surface of the side 23. That is, the adhesive layer 3 covers the arc-shaped surface 21, the tip 22, and the side 23. The arc-shaped surface 21 has a plurality of first slots 24. The inner wall of the adhesive layer 3 extends into the first slots 24 to form first locking blocks 31, which engage with the corresponding first slots 24.

[0023] This utility model discloses a rubber-metal integrated clamping gripper with a simple structure. The tip 22, curved surface 21, and side 23 of the metal clamping block 2 are all covered by an adhesive layer 3. During clamping, the workpiece will not directly contact the relatively hard clamping block 2, fundamentally avoiding scratches, indentations, or rigid impact damage to the workpiece surface caused by the metal clamping block 2. Furthermore, the adhesive layer 3 covers the tip 22 of the clamping block 2, reducing the risk of damage from direct pressure from the metal tip. Simultaneously, the adhesive layer 3 has good elasticity and deformation capacity. When the driving component 1 drives the clamping gripper to apply clamping force, the adhesive layer 3 will slightly deform according to the shape of the workpiece surface, ensuring stable clamping force while buffering excessive local pressure, preventing deformation, chipping, or cracking of the workpiece due to stress concentration. When the workpiece is clamped, the adhesive layer 3 at the tip 22 provides precise positioning protection, the adhesive layer 3 at the curved surface 21 provides large-area force buffering, and the adhesive layer 3 at the side 23 provides lateral stability protection. These three elements work together to form a comprehensive protection system, effectively protecting the workpiece. Meanwhile, the first slot 24 of the arc surface 21 of the clamping block 2 engages with the first block 31 of the adhesive layer 3, ensuring a firm connection between the adhesive layer 3 and the metal clamping block 2, enhancing the bonding strength between the rubber and the metal, and preventing the adhesive layer 3 from falling off during repeated clamping and deformation.

[0024] In this embodiment, the adhesive layer 3 is made of rubber. Rubber has high elasticity and low hardness. Using an adhesive layer 3 made of rubber to cover the clamping block 2 can prevent the metal clamping block 2 from damaging the workpiece.

[0025] Furthermore, a second slot 25 is provided on the side of the tip 22 away from the curved surface 21, and a second locking block 32 extends from the inner wall of the adhesive layer 3 into the second slot 25, engaging with the second slot 25. This engagement structure between the second slot 25 of the curved surface 21 of the clamping block 2 and the second locking block 32 of the adhesive layer 3 ensures a secure connection between the adhesive layer 3 and the tip 22 of the metal clamping block 2, preventing the adhesive layer 3 from lifting or falling off from the edge of the tip 22.

[0026] Furthermore, a third slot 26 is formed on the surface of the side portion 23, and a third locking block 33 extends from the inner wall of the adhesive layer 3 into the third slot 26, the third locking block 33 engaging with the third slot 26. This engagement structure between the third slot 26 of the side portion 23 of the clamping block 2 and the third locking block 33 of the adhesive layer 3 ensures a firm connection between the adhesive layer 3 and the side portion 23 of the metal clamping block 2, preventing problems such as edge lifting or peeling of the adhesive layer 3 on the side portion 23.

[0027] Furthermore, multiple first slots 24 are spaced apart circumferentially along the curved surface 21 to ensure a tight fit between the adhesive layer 3 and the curved surface 21.

[0028] Furthermore, the number of clamping hands is two, and the two clamping hands are arranged opposite each other. The two arc-shaped surfaces 21 are respectively arranged on the opposite surfaces of the two clamping hands. The driving member 1 drives the two clamping hands to open and close to clamp the workpiece.

[0029] Furthermore, the surface of the adhesive layer 3 is provided with multiple anti-slip protrusions 4, which enhance the static friction of the clamping block 2 and can stably clamp the workpiece. In this embodiment, the anti-slip protrusions 4 are made of rubber.

[0030] Furthermore, the multiple anti-slip protrusions 4 are distributed in a matrix on the adhesive layer 3 located on the curved surface 21, which can greatly improve the clamping friction.

[0031] Furthermore, the driving component 1 is a cylinder. In this embodiment, the cylinder is a conventional cylinder. Specifically, the driving end of the cylinder is provided with two opposing moving blocks. The cylinder drives the two moving blocks to move closer or further away from each other. Each clamping block 2 is connected to the cylinder through the moving block.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
