Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal rod clamping technology, and in particular to a stable clamping device for metal rods. Background Technology
[0002] In materials science and engineering, hardness testing is a fundamental process for determining a material's resistance to deformation. One of the most common methods is the Brinell hardness test, renowned for its simplicity and effectiveness. Online hardness testers are testing devices used for real-time monitoring and control of material hardness, widely applied in industrial production and quality control. They apply pressure to the sample surface using an indenter with a certain pressure, then measure the indentation diameter to calculate the hardness value, ensuring the stability and consistency of material hardness during production.
[0003] In general, the materials tested by online hardness testers are mostly cylindrical metal rods. These rods are moved on the production line by transmission rollers to achieve testing and transfer. When loading and unloading the cylindrical metal rods at both ends of the production line, robotic arms are usually used to grip them. However, when the size and weight of the cylindrical material are too large, the robotic arms have difficulty completing the gripping task due to force issues.
[0004] Therefore, this utility model proposes a metal rod stabilizing clamping device. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable clamping device for metal rods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal rod stabilizing clamping device, comprising a mounting frame and a support plate fixedly connected to the bottom of the mounting frame. A set of mounting seats is fixedly connected to the front and rear sides of the upper surface of the support plate. Each set of mounting seats consists of two seats, and the two sets of mounting seats are staggered. A cylinder is fixedly mounted on the top of each mounting seat. A movable block is fixedly connected to the piston end of each cylinder. The lower surfaces of the two movable blocks corresponding to each set of mounting seats are fixedly connected to the same linkage plate. Several grippers are fixedly connected to the lower surfaces of the two linkage plates.
[0007] Furthermore, the grippers at each pair of positions below the two linkage plates form a group, and each group of grippers is arranged opposite to each other, with the inner sides of multiple groups of grippers jointly holding the same cylindrical iron bar.
[0008] Furthermore, the upper surface of the support plate is fixedly connected with multiple slide rails, and each slide rail is symmetrically fitted with a support block that is slidably connected. The upper surfaces of two support blocks are respectively fixedly connected to the lower surface of the corresponding linkage plate.
[0009] Furthermore, the mounting base includes a fixed base and a connecting plate. The lower surface of the fixed base is fixedly connected to the support plate, the lower surface of the connecting plate is fixedly connected to the fixed base, and the top of the connecting plate is fixedly connected to one end of the corresponding cylinder.
[0010] Furthermore, the gripper has a groove-shaped structure, and the gripper includes a side plate and a bottom plate, with the bottom plate fixedly connected to the bottom of the side plate.
[0011] Furthermore, the inner side of the base plate has an inclined structure, and when two corresponding grippers in each group abut against each other, the bottoms of the two grippers together form a V-shaped structure.
[0012] Furthermore, the sidewall of the support plate is symmetrically provided with multiple limiting grooves, and the gripper is inserted into the support plate through the limiting groove.
[0013] This utility model has the following beneficial effects: In use, this utility model's metal rod stabilizing clamping device comprises a support plate, mounting base, cylinder, movable block, support block, slide rail, and multiple sets of clamping claws. The clamping claws adopt a grooved structure and are made of stainless steel, enabling them to withstand significant forces. When the two clamping claws are clamped, the bottom of the claws forms a V-shape. By fixing multiple pairs of grooved clamping claws at equal intervals, cylindrical materials of different diameters and lengths can be clamped. At the same time, the presence of the slide rail and support block allows the clamping claws to move more smoothly and steadily when driven by the cylinder, thereby achieving the opening and clamping of the claws.

[0016] Figures 1 to 3As shown, a metal rod stabilizing clamping device is disclosed, including a mounting frame 2 and a support plate 3 fixedly connected to the bottom of the mounting frame 2. A set of mounting seats 4 are fixedly connected to the front and rear sides of the upper surface of the support plate 3. There are two mounting seats 4 in each set, and the two sets of mounting seats 4 are staggered. A cylinder 5 is fixedly installed on the top of each mounting seat 4. A movable block 6 is fixedly connected to the piston end of each cylinder 5. The lower surfaces of the two movable blocks 6 corresponding to each set of mounting seats 4 are fixedly connected to the same linkage plate 7. Several grippers 8 are fixedly connected to the lower surfaces of the two linkage plates 7. The grippers 8 are made of stainless steel and can withstand large forces. When the cylinder 5 is running, the displacement of its piston end can drive the connected movable block 6 to move, thereby driving the linkage plate 7 and the gripper 8 below the linkage plate 7 to move. Specifically, each pair of corresponding grippers 8 below the two linkage plates 7 forms a group. Each group of grippers 8 is arranged opposite to each other, and the inner sides of multiple groups of grippers 8 jointly clamp the same cylindrical iron rod 1. The grippers 8 have a groove-shaped structure (i.e., the cross-section is U-shaped). The grippers 8 include a side plate 801 and a bottom plate 802. The bottom plate 802 is fixedly connected to the bottom of the side plate 801. The inner side of the bottom plate 802 has an inclined structure. When each pair of corresponding grippers 8 abuts (i.e., the two grippers 8 are clamped), the bottoms of the two grippers 8 jointly form a V-shaped structure. The linkage plates 7 fix multiple pairs of groove-shaped grippers 8 at equal intervals. Under the joint clamping action of multiple groups of grippers 8, cylindrical materials of different diameters and lengths (such as the cylindrical iron rod 1 mentioned above) can be clamped.
[0017] Correspondingly, the side wall of the support plate 3 is symmetrically provided with multiple limiting grooves 9. The grippers 8 are inserted into the support plate 3 through the limiting grooves 9. Each pair of limiting grooves 9 on the side wall of the support plate 3 forms a set. Each set of limiting grooves 9 corresponds to a set of grippers 8. There is a certain distance between each set of limiting grooves 9 so that when the two grippers 8 approach each other, there is a minimum gap. The two grippers 8 can abut together, but will not be damaged by excessive impact.
[0018] Mounting base 4 includes a fixed base 401 and a connecting plate 402. The lower surface of the fixed base 401 is fixedly connected to the support plate 3, and the lower surface of the connecting plate 402 is fixedly connected to the fixed base 401. The top of the connecting plate 402 is fixedly connected to one end of the corresponding cylinder 5, that is, the end of the cylinder 5 away from the piston end is connected to the mounting base 4, thereby mounting the cylinder 5 above the support plate 3. The connecting plate 402 has a triangular structure, which is more stable.
[0019] The upper surface of the support plate 3 is fixedly connected with multiple slide rails 10. Each slide rail 10 has a support block 11 symmetrically fitted and slidably connected on its outer surface. The upper surfaces of the two support blocks 11 are fixedly connected to the lower surface of the corresponding linkage plate 7. The support block 11 can slide along the slide rail 10 following the displacement of the corresponding linkage plate 7, making the gripper 8 move more smoothly and stably when it moves horizontally.
[0020] When using the metal bar stabilizing clamping device, on the production line of the online hardness tester for Brinell hardness testing, when the cylindrical material (cylindrical iron bar 1) reaches the end of the production line, the V-shaped lifting module at the end of the production line lifts the cylindrical material, and the overhead beam drives the open gripper 8 to move to the designated position (the above-mentioned production line, V-shaped lifting module, and overhead beam are all common mechanical equipment in existing production lines). The brake cylinder 5 retracts, causing the gripper 8 to clamp, and the overhead beam then drives the gripper 8 to move upward to the designated material storage point. During the above-mentioned material feeding process, the gripper 8 adopts a groove-shaped structure and is made of stainless steel, which can withstand greater force. When the two grippers 8 are clamped, the bottom of the gripper 8 is V-shaped. By fixing multiple pairs of groove-shaped grippers 8 at equal intervals, cylindrical materials of different diameters and lengths can be clamped. At the same time, the presence of the slide rail 10 and the support block 11 makes the gripper 8 more stable and smooth when it is driven to move by the cylinder 5, thereby realizing the opening and clamping of the gripper 8. The gripper device designed in this paper has a stable structure and is corrosion resistant. It can effectively solve the problem of clamping large and heavy cylindrical materials, and greatly improve work efficiency.
[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
