Description

Technical Field

[0001] This utility model relates to a clamping device for tubular materials, belonging to the field of gripper devices. Background Technology

[0002] In industrial production, the automated gripping and transfer of tubular materials (such as metal pipes, plastic pipes, and cylindrical workpieces) is a common process. Currently widely used gripping equipment, especially fixtures with V-groove designs (such as robotic grippers and pneumatic grippers), has significant structural defects that severely limit its application scenarios and reliability.

[0003] Grippers with V-groove designs often cannot grip tubular materials located on flat surfaces. Specifically, the bottom tip of the V-groove needs to be inserted under the material to achieve clamping, but when the material is laid flat on a conveyor belt, worktable, or other flat surface, the bottom tip of the groove is blocked by the surface and cannot descend to an effective clamping position. Even if the gripper is forced down, the two arms of the V-groove can only contact a small portion of the curved surface at the top of the tubular material, resulting in a smaller contact area than conventional suspended clamping, and extremely weak and unstable clamping force.

[0004] This defect renders V-groove clamps virtually unusable in scenarios requiring direct pickup of tubular materials from flat surfaces (such as conveyor belts, trays, and machine tool tables), severely restricting the layout and efficiency of automated production lines. Operators are often forced to use manual assistance or design complex lifting mechanisms to suspend the material in the air, increasing costs and potential points of failure.

[0005] In view of this, it is indeed necessary to propose a new gripping device to solve the above problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a clamping device for tubular materials, which can clamp tubular materials located on a plane.

[0007] The technical solution of this utility model is:

[0008] A clamping device for tubular materials includes a clamping module and a supporting module. In a vertical direction perpendicular to the horizontal plane, the clamping module is located above the supporting module and has a clamping portion movable toward the supporting module. The clamping portion includes two clamping arms arranged in a V-shape, the two clamping arms being arranged opposite each other to form a clamping area. The supporting module includes a supporting block and a movable block arranged opposite the clamping portion and movable vertically relative to the supporting block. The tubular material is placed on both the supporting block and the movable block. When the clamping portion moves toward the supporting module, the bottom of the clamping portion abuts against the movable block and squeezes the movable block downwards relative to the supporting block, causing the tubular material on the supporting block to enter the clamping area.

[0009] As a further improvement of this utility model, the supporting block has a groove on the side facing the clamping part, the movable block is received in the groove, and the upper surface of the movable block is flush with the upper surface of the supporting block.

[0010] As a further improvement of this utility model, the groove is provided with an elastic mechanism, and the movable block is provided with a receiving groove for partially accommodating the elastic mechanism. When the elastic mechanism is in the normal state, the upper surface of the movable block is flush with the upper surface of the support block. When the elastic mechanism is in the deformed state, the movable block moves downward relative to the support block.

[0011] As a further improvement of this utility model, both the support block and the movable block are provided with a placement groove on their tops, and the two placement grooves are interconnected to form a placement area for placing the tubular material. The extension direction of the placement area is perpendicular to the movement direction of the clamping part.

[0012] As a further improvement of this utility model, in the extension direction of the placement area, the end of the supporting block away from the movable block is also provided with a first assembly groove, the first assembly groove accommodating a transition block, and the transition block being provided with a corresponding transition groove adapted to the placement area.

[0013] As a further improvement of this utility model, the tubular material is at least partially exposed outside the placement area.

[0014] As a further improvement of this utility model, in the extending direction of the placement area, the placement area has a feed inlet, and the support block is also provided with a second assembly groove. The second assembly groove is located on the side of the movable block away from the feed inlet and contains a stop block. The stop block abuts against the tubular material and separates the placement area.

[0015] As a further improvement of this utility model, the clamping module also includes a slide rail connected to the clamping part. The slide rail includes a first slide rail and a second slide rail that are independent of each other, and the extension directions of the first slide rail and the second slide rail are perpendicular to each other.

[0016] As a further improvement of this utility model, the horizontal direction is defined as the first direction and the vertical direction as the second direction. The clamping module can move along the first slide rail in the first direction and along the second slide rail in the second direction.

[0017] As a further improvement of this utility model, in the first direction, the clamping device further includes a feeding module, the clamping module being configured to transport the tubular material clamped in the second direction to the feeding module in the first direction.

[0018] The beneficial technical effects of this utility model are as follows: The clamping device for tubular materials of this utility model is provided with a movable block that can move up and down relative to the support block on the support module. When the tubular material is placed on the support block and the movable block at the same time, the clamping part moves towards the support module, so that the bottom of the clamping part abuts against the movable block and squeezes the movable block to move downward relative to the support block, so that the tubular material on the support block enters the clamping area of ​​the clamping part. In this way, the problem of clamping tubular materials on a plane is solved, ensuring that the tubular material is firmly fixed and practical. Attached Figure Description

[0024] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Please see Figures 1 to 5 As shown, this utility model discloses a clamping device 100 for tubular materials 200. The clamping device includes a clamping module 1 and a supporting module 2. In a vertical direction perpendicular to the horizontal plane, the clamping module 1 is located above the supporting module 2. The supporting module 2 is used to fix the tubular material 200 for clamping by the clamping module 1.

[0026] The clamping module 1 has a clamping part 11 that can move toward the supporting module 2. The clamping part 11 includes two clamping arms 111 arranged in a V-shape, and the two clamping arms 111 are arranged opposite each other to form a clamping area 110. In this embodiment, the clamping area 100 can be regarded as being composed of two V-shaped grooves to restrict the tubular material 200 360 degrees.

[0027] The support module 2 includes a support block 21 and a movable block 22 that is disposed opposite to the clamping part 11 and can move up and down relative to the support block 21. The tubular material 200 is placed on both the support block 21 and the movable block 22. When the clamping part 11 moves toward the support module 2, the bottom of the clamping part 11 abuts against the movable block 22 and squeezes the movable block 22 to move downward relative to the support block 21, so that the tubular material 200 located on the support block 21 enters the clamping area 110.

[0028] Preferably, the upper surfaces of the support block 21 and the movable block 22 are flush, so that the tubular material 200 is located on a plane. The support block 21 has a groove 210 on the side facing the clamping part 11, and the movable block 22 is received in the groove 210.

[0029] The groove 210 is provided with an elastic mechanism 23, and the movable block 22 is provided with a corresponding receiving groove for partially accommodating the elastic mechanism 23. When the elastic mechanism 23 is in the normal state, the upper surface of the movable block 22 is flush with the upper surface of the support block 21. When the elastic mechanism 23 is in the deformed state, the movable block 22 moves downward relative to the support block 21.

[0030] Both the supporting block 21 and the movable block 21 are provided with a placement groove 20 on their tops. The two placement grooves 20 are interconnected to form a placement area for placing the tubular material 200. The extension direction of the placement area is perpendicular to the movement direction of the clamping part 11. In this embodiment, the tubular material 200 is at least partially exposed outside the placement area.

[0031] Preferably, in the extension direction of the placement area, the end of the supporting block 21 away from the movable block 22 is further provided with a first assembly groove 211, the first assembly groove 211 accommodating a transition block 24, and the transition block 24 correspondingly provided with a transition groove 240 adapted to the placement area. Preferably, the tubular material 200 enters the placement area through the transition groove 240.

[0032] In the extending direction of the placement area, the placement area has a feed inlet, and the support block 21 is also provided with a second assembly groove 212. The second assembly groove 212 is located on the side of the movable block 22 away from the feed inlet and accommodates a stop block 25. The stop block 25 abuts against the tubular material 200 and separates the placement area. The feed inlet is the entrance located near the transition groove 240. Alternatively, the side of the transition groove 240 away from the placement area can also be used as the feed inlet. The stop block 25 can also limit the tubular material 200 in a horizontal direction.

[0033] The clamping module 1 further includes a slide rail 12 connected to the clamping part 11. The slide rail 12 includes a first slide rail 121 and a second slide rail 122 that are independent of each other. The extension directions of the first slide rail 121 and the second slide rail 122 are perpendicular to each other.

[0034] The horizontal direction is defined as the first direction, and the vertical direction as the second direction. The gripping module 1 can move along the first slide rail 121 in the first direction and along the second slide rail 122 in the second direction. In the first direction, the gripping device 100 further includes a discharging module 3. The gripping module 1 is configured to transport the tubular material 200 gripped in the second direction to the discharging module 3 in the first direction.

[0035] In summary, the clamping device 100 for tubular materials 200 of this utility model, by providing a movable block 22 on the support module 2 that can move up and down relative to the support block 21, allows the clamping part 11 to move towards the support module 2 when the tubular material 200 is placed on both the support block 21 and the movable block 22. This causes the bottom of the clamping part 11 to abut against the movable block 22 and compress the movable block 22 to move downward relative to the support block 21, allowing the tubular material 200 on the support block 21 to enter the clamping area 110 of the clamping part 11. In this way, the problem of clamping the tubular material 200 on a plane is solved, ensuring that the tubular material 200 is firmly fixed and practical.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
