Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to an anti-slip clamp for adaptive irregularly shaped parts. Background Technology

[0002] In modern industrial production, the requirements for fixtures in parts processing and transportation are becoming increasingly stringent. Traditional fixtures, due to their fixed structure and single function, are difficult to adapt to irregularly shaped parts. Frequent fixture changes not only increase the production cost of irregularly shaped parts, but also seriously affect production efficiency. Moreover, during the clamping process, hard materials are easily damaged on the surface of parts, and poor anti-slip performance also makes parts easy to fall off during transportation, which cannot meet the needs of high-quality and high-efficiency production.

[0003] A search revealed that publication number CN110814373A discloses an adaptive clamp, comprising a conical base, a spherical base, and a chuck mechanism connected in sequence. A conical groove is provided on the end face of the conical base facing the spherical base, and the sidewall of the conical groove is conical. The end face of the spherical base facing the conical base has a chamfered edge that abuts against the conical surface of the groove. A pull rod passes through the conical base, and a washer is fitted onto the pull rod. One side of the washer is spherical and abuts against the transition section of the pull rod, while the other side abuts against a positioning element, which is threadedly connected to the spherical base. The chuck mechanism is mounted on the end face of the spherical base facing away from the conical base. The pull rod and the washer are spherically fitted, allowing free rotation between them. The spherical base and the conical base are in contact via a spherical and conical surface, also allowing free rotation. Therefore, this clamp can achieve a completely self-adaptive state, eliminating manufacturing errors. Furthermore, the chuck mechanism has excellent adaptability, facilitating the clamping of various irregularly shaped parts. In the process of developing this invention, the inventors discovered the following problems with the existing technology:

[0004] Existing fixtures with fixed structures require frequent changes of the entire fixture set when dealing with parts of different specifications, resulting in high costs and low efficiency. In addition, existing fixtures without flexible compensation use hard materials to directly clamp parts, which not only easily leaves indentations and causes damage to the surface of the parts, but also have poor anti-slip performance, making it easy for parts to slip and fall off during transportation. This cannot meet diverse production needs, nor can it guarantee the quality of parts and transportation safety.

[0005] Therefore, an anti-slip clamp with adaptive irregular parts is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-slip clamp with adaptive irregular parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-slip clamp for adaptive irregular parts, comprising a drive assembly, a clamping mechanism, a bracket assembly and an installation assembly, wherein the drive assembly is installed below the installation assembly, and the clamping mechanism is installed below the drive assembly, and the bracket assembly is provided on the side of the clamping mechanism.

[0008] Preferably, the drive assembly includes a cylinder, a push rod, and a push plate, with the push rod mounted below the cylinder and the push plate mounted below the push rod.

[0009] Preferably, the clamping mechanism includes a transmission component, a limiting component, and a gripping component, wherein the limiting component is installed below the transmission component, and the gripping component is installed below the limiting component.

[0010] Preferably, the transmission assembly includes a first transmission rod, a second transmission rod, and a fixed spring, wherein the fixed spring is mounted on the side of the first transmission rod, and the second transmission rod is mounted on the side of the fixed spring away from the first transmission rod.

[0011] Preferably, the limiting component includes a limiting rod, a first limiting ring, and a second limiting ring, wherein the first limiting ring is mounted on the outer diameter surface of the limiting rod, and the second limiting ring is provided on the side of the first limiting ring.

[0012] Preferably, the gripping component includes a connecting plate, a clamping plate, and a rubber pad, with the clamping plate installed below the connecting plate and the rubber pad installed on the side of the clamping plate.

[0013] Preferably, the bracket assembly includes a limiting plate, a first sliding groove plate and a second sliding groove plate, wherein the first sliding groove plate is installed on the side of the limiting plate and the second sliding groove plate is installed on the side of the limiting plate away from the first sliding groove plate.

[0014] Preferably, the mounting assembly includes a placement box, a first mounting bracket, and a second mounting bracket, with the first mounting bracket mounted on top of the placement box and the second mounting bracket provided on the side of the first mounting bracket.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this anti-slip clamp with adaptive irregular parts can flexibly adjust the opening size of the gripping component through the coordinated cooperation of the drive component, clamping mechanism, bracket component and mounting component. For example, the design of the first transmission rod, the second transmission rod and the fixed spring in the transmission component can change the opening and closing state of the clamping mechanism under the action of the push plate. The limiting component can ensure the gripping accuracy, thereby realizing adaptive clamping of irregular parts of different specifications, reducing the cost of changing clamps when the equipment grips parts of different specifications.

[0017] 2. Compared with the prior art, this anti-slip clamp with adaptive irregular parts has a high coefficient of friction rubber pad on the side of the clamping plate of the gripping component. The surface texture increases the contact friction with the parts, effectively preventing the parts from sliding. At the same time, the elasticity of the rubber pad can buffer the clamping force, avoid damage to the surface of the parts, and fill the gaps on the surface of the parts to enhance the fit. This not only ensures the stability of the parts during transportation, but also protects the surface quality of the parts. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 4 The anti-slip clamp with adaptive irregular parts shown includes a drive assembly 1, a clamping mechanism 2, a bracket assembly 3 and a mounting assembly 4. The drive assembly 1 is mounted below the mounting assembly 4, the clamping mechanism 2 is mounted below the drive assembly 1, and the bracket assembly 3 is provided on the side of the clamping mechanism 2.

[0026] Specifically: When the operator needs to clamp and transport the part using the fixture, the fixture needs to be fixedly connected to the robotic arm through the mounting component 4. Then, the robotic arm is started to move the fixture above the part. At this time, the drive component 1 of the fixture will press down on the clamping mechanism 2 to open the clamping mechanism 2. During this process, the support component 3 will limit the downward vertical movement of the clamping mechanism 2 to prevent its displacement from deviating. When the robotic arm controls the two sides of the fixture to surround the part, the drive component 1 will drive the clamping mechanism 2 to move upward to clamp the part.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the drive assembly 1 includes a cylinder 5, a push rod 6, and a push plate 7. The push rod 6 is installed below the cylinder 5, and the push plate 7 is installed below the push rod 6. After compressed air is introduced into the cylinder 5, the internal piston is pushed downward by the air pressure, which drives the push rod 6 to move vertically downward. The push plate 7 at the end of the push rod 6 moves downward synchronously, thereby driving the clamping mechanism 2 to operate. During the downward movement of the push plate 7, the slide groove in the bracket assembly 3 will limit its movement.

[0030] In a preferred embodiment, the clamping mechanism 2 includes a transmission component 8, a limiting component 9, and a gripping component 10. The limiting component 9 is installed below the transmission component 8, and the gripping component 10 is installed below the limiting component 9. The transmission component 8 and the drive component 1 are hingedly connected, and the transmission component 8 and the gripping component 10 are hingedly connected. When gripping an object, the drive component 1 will drive the transmission component 8 to swing. When the transmission component 8 swings, the gripping component 10 will also move horizontally under the limitation of the limiting component 9 to grip the object.

[0031] In a preferred embodiment, the transmission assembly 8 includes a first transmission rod 11, a second transmission rod 12, and a fixing spring 13. The fixing spring 13 is mounted on the side of the first transmission rod 11, and the second transmission rod 12 is mounted on the side of the fixing spring 13 away from the first transmission rod 11. The push plate 7 presses the first transmission rod 11 and the second transmission rod 12 downward, causing the first transmission rod 11 and the second transmission rod 12 to slide outward, thereby opening the clamping mechanism 2 as a whole. When the drive assembly 1 retracts upward, the gripping assembly 10 moves horizontally inward along the limiting assembly 9, and the fixing spring 13 provides relative buffering for the movement of the first transmission rod 11 and the second transmission rod 12.

[0032] In a preferred embodiment, the limiting assembly 9 includes a limiting rod 14, a first limiting ring 15, and a second limiting ring 16. The first limiting ring 15 is mounted on the outer diameter surface of the limiting rod 14, and the second limiting ring 16 is provided on the side of the first limiting ring 15. The limiting rod 14 passes through the first limiting ring 15 and the second limiting ring 16. When the first transmission rod 11 and the second transmission rod 12 swing, the connecting plate 17 will move horizontally along the limiting rod 14, while the limiting ring limits its maximum displacement to prevent the clamping plate 18 from opening and closing excessively, which could cause parts to fall off or the mechanism to be damaged. The limiting rod 14 also ensures that the connecting plate 17 moves in the horizontal direction, preventing the gripping assembly 10 from shifting during clamping and ensuring gripping accuracy.

[0033] In a preferred embodiment, the gripping component 10 includes a connecting plate 17, a clamping plate 18, and a rubber pad 19. The clamping plate 18 is installed below the connecting plate 17, and the rubber pad 19 is installed on the side of the clamping plate 18. The transmission component 8 drives the clamping plate 18 to close through the connecting plate 17, forming a clamping force. The rubber pad 19 on the surface of the clamping plate 18 is made of a high-friction coefficient material. Its surface texture increases the contact friction with the part, preventing slippage. The elasticity of the rubber pad 19 can buffer the clamping force, avoid causing indentations on the surface of the part, and fill the gaps on the surface of the part to enhance the fit.

[0034] In a preferred embodiment, the support assembly 3 includes a limiting plate 20, a first sliding groove plate 21, and a second sliding groove plate 22. The first sliding groove plate 21 is installed on the side of the limiting plate 20, and the second sliding groove plate 22 is installed on the side of the limiting plate 20 away from the first sliding groove plate 21. The push plate 7 of the clamping mechanism 2 is connected to the first sliding groove plate 21 and the second sliding groove plate 22 through a slider. The push plate 7 is slidably connected to the first sliding groove plate 21, and the push plate 7 is also slidably connected to the second sliding groove plate 22. It can move vertically in the groove, so that the clamping mechanism 2 can adjust the opening size of the gripping assembly 10 according to the specifications of different models of parts to grip the parts. The limiting plate 20 connects the first sliding groove plate 21 and the second sliding groove plate 22, and the limiting plate 20 and the push rod 6 are slidably connected.

[0035] In a preferred embodiment, the mounting assembly 4 includes a placement box 23, a first mounting bracket 24, and a second mounting bracket 25. The first mounting bracket 24 is mounted on the top of the placement box 23, and the second mounting bracket 25 is provided on the side of the first mounting bracket 24. The first mounting bracket 24 and the second mounting bracket 25 are connected to external equipment by snap-fit ​​to provide rigid support. The placement box 23 is used to store components such as air pipes and wires of the drive assembly 1 to prevent exposed wiring from affecting operation and to protect internal components.

[0036] The working process of this utility model is as follows: First, the anti-slip clamp with adaptive irregular parts achieves part clamping through the coordinated operation of various components. The mounting component 4 consists of a placement box 23, a first mounting bracket 24, and a second mounting bracket 25. The first mounting bracket 24 and the second mounting bracket 25 are connected to the external robotic arm by buckles to provide rigid support. The placement box 23 is used to store components such as air pipes and wires of the drive component 1. The drive component 1 includes a cylinder 5, a push rod 6, and a push plate 7. After compressed air is connected to the cylinder 5, the internal piston is pushed by the air pressure, which drives the push rod 6 vertically. As the device moves downward, the push plate 7 moves downward in sync. The clamping mechanism 2 consists of a transmission assembly 8, a limiting assembly 9, and a gripping assembly 10. The first transmission rod 11 and the second transmission rod 12 in the transmission assembly 8 slide outward under the pressure of the push plate 7, causing the clamping mechanism 2 to open. The fixed spring 13 provides cushioning for its movement. The limiting rod 14 in the limiting assembly 9 passes through the first limiting ring 15 and the second limiting ring 16. When the first transmission rod 11 and the second transmission rod 12 swing, the connecting plate 17 of the gripping assembly 10 moves horizontally along the limiting rod 14. The limiting ring restricts its maximum displacement to ensure gripping accuracy.

[0037] The clamping plate 18 of the gripping component 10 is connected to the transmission component 8 through the connecting plate 17. The rubber pad 19 on the side of the clamping plate 18 is made of a high friction coefficient material, which can buffer the clamping force and enhance the fit. The bracket component 3 consists of a limiting plate 20, a first sliding groove plate 21, and a second sliding groove plate 22. The pushing plate 7 is slidably connected to the first sliding groove plate 21 and the second sliding groove plate 22 through a slider, so that the pushing plate 7 can move vertically in the groove. This allows the clamping mechanism 2 to adjust the opening size of the gripping component 10 according to the part specifications. At the same time, the limiting plate 20 connects the first sliding groove plate 21 and the second sliding groove plate 22 and is slidably connected to the pushing rod 6 to ensure the overall stable operation. The above is the working principle of this anti-slip clamp with adaptive irregular parts.
