Description

Technical Field

[0001] This utility model relates to a mechanical feeding device, and more particularly to a split-type feeding clamp. Background Technology

[0002] In automated production lines, feed clamps are key components for rapid workpiece transfer. Existing feed clamps generally employ an integrated "base + moving gripper" architecture. This rigid connection mechanism results in poor spatial adaptability, and the bulky, integrally cast clamp volume forces manufacturers to increase clamping space and overall equipment height in scenarios with limited Z-axis height, leading to a 20%-35% increase in equipment costs. Furthermore, the reliability of the connection between existing clamp bodies is poor, frequently resulting in connection breakage and failure. Therefore, reducing the feed clamp volume while improving connection reliability and stability are the urgent technical problems to be solved in this case. Utility Model Content

[0003] To address the above problems, this utility model provides a split-type feeding clamp with a compact structure that meets the operational needs of small workspaces and improves connection reliability and stability.

[0031] The following is for reference. Figure 1-3 Describe this utility model;

[0032] A split-type feeding clamp, comprising:

[0033] The main clamping body 100 includes a clamping part 101 and a main clamping part 102 that are fixedly connected; a hinge part 103 protruding outward is provided between the clamping part 101 and the main clamping part 102; a first clamping position 1021 adapted to the object to be clamped is provided on the inner side of the main clamping part 102.

[0034] The clamping part 101 is plate-shaped and has several mounting holes for fixed connection with the telescopic end of the linear drive mechanism.

[0035] Linear drive mechanisms include cylinders, hydraulic cylinders, electric actuators, or linear modules.

[0036] The main clamping part 102 is fixedly mounted on the clamping part 101 via a first connecting member.

[0037] The auxiliary clamp 200 has one end hinged to the hinge part 103, and the other end has a second clamping position 2021 adapted to the object being clamped.

[0038] The auxiliary clamp 200 includes an auxiliary hinge joint 201 and an auxiliary clamping part 202 that are fixedly connected;

[0039] The auxiliary hinge joint 201 and the auxiliary clamping part 202 are fixedly connected by a second connector.

[0040] The second clamping position 2021 is located on the side of the auxiliary clamping part 202.

[0041] The auxiliary hinge joint 201 is provided with a plate-shaped hinge plate;

[0042] The hinge portion 103 is provided with a hinge cavity adapted to the hinge plate. The side of the hinge plate facing the hinge portion 103 has an arc-shaped structure, which facilitates rotational movement within the hinge portion 103.

[0043] The outer end of the hinge 103 has an arc-shaped structure.

[0044] A torsion spring 300 is disposed on the hinge portion 103, one end of which is connected to the main clamping body (100) and the other end of which is connected to the auxiliary clamping body 200. The torsion spring 300 forms a clamping cavity adapted to the object to be clamped by the first clamping position 1021 and the second clamping position 2021.

[0045] The hinge section 103 in this design features a hollow structure in the middle. The hinge plate is directly inserted into the hinge section 103 of the hollow structure, meaning that the hinge plate is fitted against the inner wall of the hollow structure from top to bottom, and is hinged by a hinge post. The hinge post extends from the top surface of the hinge section 103 and is equipped with a mounting seat adapted to the torsion spring 300. The mounting seat is sleeved on the hinge post, and the torsion spring is sleeved inside the mounting seat, ensuring a stable and reliable connection between the main clamp 100, the auxiliary clamp 200, and the torsion spring 300.

[0046] Meanwhile, the auxiliary clamping part 202 and the main clamping part 102 are detachably and fixedly mounted on the corresponding auxiliary clamping body 200 and the main clamping body 100, respectively. This facilitates the replacement of clamping cavities of different specifications and reduces the replacement and maintenance costs after wear. In other words, there is no need to replace the clamping part 101 and the auxiliary hinge joint 201, which improves the efficiency of later maintenance and reduces maintenance costs.

[0047] The inner corners of the main gripping part 102 and / or the auxiliary gripping body 200 (the inner sides of the mating surfaces of the main gripping part 102 and the auxiliary gripping body 200) are chamfered;

[0048] The workpiece slides into the side of the horizontal pusher arm through the material chute. The horizontal pusher arm pushes the workpiece towards the feeding clamp. The workpiece opens the feeding clamp through its inner corner, and the workpiece continues to be pushed until it enters the clamping cavity. Then, the horizontal pusher arm retracts, completing the clamping of the workpiece. The feeding clamp feeds the workpiece into the worktable via a linear drive mechanism.

[0049] The cross-section of the clamping cavity in this case is circular or polygonal, which can be adapted to the workpiece being clamped.
