Description

Technical Field

[0001] This utility model relates to the field of round steel clamping technology, specifically a clamping tool for processing metal round steel. Background Technology

[0002] Steel is a solid, long steel bar with a circular cross-section. According to the processing technology, it can be divided into three types: hot rolling, forging, and cold drawing. It is a commonly used raw material in machining. When processing round steel, it is necessary to first use a round steel clamp to fix it.

[0003] A round steel clamp, authorized by publication number CN216265541U, includes a worktable with two first sliding grooves inside. A housing is fixedly connected to the bottom surface of the worktable, and a cylindrical shaft is rotatably connected inside the housing. A gear is fixedly connected to the outer surface of the cylindrical shaft, and a first spring is fixedly connected inside the housing. Through the cooperation between the clamping mechanism and the gear, the round steel can be more securely fixed, preventing slippage during processing. A replacement mechanism allows for easier replacement of the curved clamp, thus facilitating the processing of the round steel. Round steel bars of different diameters are fixed by the cooperation of limiting holes, push plates, third right-angle plates and U-shaped rods. After the push plate is pushed to fix the round steel bars, the U-shaped rod can be inserted into the limiting hole to fix the position of the push plate. Thus, the position of the arc-shaped fixture will not change during the processing of round steel bars. The clamping radius of this fixture is adjusted by replacing the arc-shaped fixture. It requires the use of various types of auxiliary parts, which is complicated and not easy to use. At the same time, the setting of the limiting hole restricts this fixture to only staged fixation, which is difficult to meet the needs of multiple hole diameter changes.

[0004] To address the aforementioned problems, a fixture for machining round metal bars is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture for processing metal round steel, which solves the problem that the clamping radius adjustment of existing fixtures in the background technology is achieved by replacing the arc-shaped fixture, which requires the use of various types of auxiliary parts, making the operation complicated and inconvenient to use. At the same time, the setting of the limiting hole restricts the fixture to only be fixed in stages, making it difficult to meet the needs of multiple hole diameter changes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp for processing round metal bars, comprising a fixed frame, a driving mechanism for driving is provided on one side of the fixed frame, a rotatable rotation adjustment mechanism is movably sleeved on one side of the driving mechanism, an adjustable clamping member is rotatably arranged between the fixed frame and the rotation adjustment mechanism, the clamping member is arranged in a circular array of three sets, the fixed frame includes a fixedly arranged lower fixed block and a disc, three sets of positioning members are provided on one side of the disc corresponding to the clamping member, the clamping member slides and engages with the positioning member, the clamping member is rotatably connected to the rotation adjustment mechanism at a fixed point, and the rotation adjustment mechanism is sleeved on the telescopic end of the driving mechanism.

[0007] Preferably, the lower fixing block is provided with a guide groove.

[0008] Preferably, the positioning element has a sliding groove inside.

[0009] Preferably, a limiting device is fixedly provided on one side of the disk, and the limiting device is provided in three sets arranged in a circular array.

[0010] Preferably, the driving mechanism includes a telescopic rod fixedly disposed on one side of the lower fixed block, the telescopic end of the telescopic rod is connected to a connecting plate, and one side of the connecting plate is connected to a through-hole clamp.

[0012] Preferably, the rotation adjustment mechanism includes a large turntable that is rotatably engaged within a limiting clip, a small turntable fixedly disposed on one side of the large turntable, and a clamping member movably disposed between the large turntable and the small turntable.

[0013] Preferably, a drive rod is fixedly provided on one side of the small turntable, and a sliding opening is provided on one side of the drive rod, with the through-hole fitting movably sleeved in the sliding opening.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a metal round steel processing fixture, which is driven and adjusted by a telescopic rod in the drive mechanism. The adjustment is relatively smooth and is not affected by the limit. It initially solves the problem that the existing fixture is limited by the limit hole and can only be fixed in stages, making it difficult to meet the needs of multiple hole diameter changes.

[0016] 2. The present invention provides a metal round steel processing fixture, which, through the synchronous adjustment of three sets of clamping components, allows the clamping diameter between the three sets of clamping components to change, thereby meeting the clamping needs of round steel of different diameters. At the same time, this structure ensures that the fixed center of the round steel remains unchanged by the synchronous adjustment of the three sets of clamping components, so as to cooperate with the external concentric motor to achieve rotation adjustment. It is simple to operate, easy to use, and highly adjustable. It solves the problem that the existing fixtures require multiple types of auxiliary parts to be used to adjust the clamping radius by replacing the arc-shaped fixture, which is complicated to operate and not conducive to use.

The fixed frame 1 includes a fixed lower fixed block 11 and a disc 13. Three sets of positioning members 14 are provided on one side of the disc 13 corresponding to the clamping member 3. The clamping member 3 and the positioning members 14 are slidably engaged. The clamping member 3 is rotatably connected to the rotation adjustment mechanism 4 at a fixed point. The rotation adjustment mechanism 4 is sleeved on the telescopic end of the driving mechanism 2.

[0027] Specifically, the extension and retraction of the drive mechanism 2 drives the rotation adjustment mechanism 4 to rotate, the positions of the disc 13 and the positioning member 14 are fixed, and the clamping member 3 is adjusted in angle by the rotation of the rotation adjustment mechanism 4. During the angle adjustment, the clamping member 3 slides along the positioning member 14. The angle adjustment of the clamping member 3 causes the clamping diameter between the three sets of clamping members 3 to change, thereby meeting the clamping needs of round steel of different diameters. At the same time, the setting of this structure allows the three sets of clamping members 3 to adjust synchronously, which can ensure that the fixed center of the round steel remains unchanged, so as to cooperate with the external concentric motor to achieve rotation adjustment. It is simple to operate, easy to use, and highly adjustable.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combination Figure 2 and Figure 3 The lower fixing block 11 has a guide groove 12, the through clamp 23 moves along the guide groove 12, the positioning member 14 has a sliding groove 141, and the sliding clamp 31 slides and engages in the sliding groove 141 to accommodate the angle adjustment of the rotating clamp 32.
