Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an eccentric supporting structure of a supporting cylinder. Background Art

[0002] In the field of automotive parts processing, especially in automated and precision machining processes, support cylinders and other mechanical support structures are often used to ensure component stability and accuracy during processing. However, existing support structures may not be able to effectively cope with complex machining environments, especially when avoiding tools, fixtures, or other components, resulting in eccentricity. In such cases, traditional support systems may cause machining errors, reducing product quality and efficiency. Therefore, it is necessary to design an eccentric support structure for support cylinders to meet current usage requirements. Utility Model Content

[0003] The utility model provides an eccentric support structure for a support cylinder, which can solve the problem that the existing fixture support structure is eccentric due to avoiding a processing tool.

The first end of the eccentric support portion is provided with a protrusion that abuts the product, and there is an eccentric distance between the axis of the protrusion and the axis of the support cylinder, which can provide more stable support and keep the parts fixed even under eccentric loads, which helps to improve the stability and reliability of the processing process.

[0005] Preferably, the eccentric support portion is L-shaped, and the second end of the eccentric support portion is provided with a slot adapted to the support block, and both sides of the slot are provided with through holes matching the hinge pin, which facilitates installation and accurate positioning.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1-7 As shown, in order to solve the problem of eccentricity caused by machining tools in the existing fixture support structure, the utility model provides the following technical solutions: an eccentric support structure of a support cylinder, comprising a mounting seat 1; a support cylinder 3, which is vertically arranged inside the mounting seat 1, and a support head 4 that can move up and down is provided on the top of the support cylinder 3; a support block 5, which is fixedly arranged above the mounting seat 1 and located on one side of the support cylinder 3; an eccentric support part 6, which is rotatably arranged on the upper part of the support block 5 through a hinge pin 7, and the eccentric support part 6 is extended toward the support head 4, and the first end of the eccentric support part 6 is provided with a protrusion 63 that abuts the product, and there is an eccentric distance 8 between the axis of the protrusion 63 and the axis of the support cylinder 3, which can provide more stable support and keep the parts fixed even under eccentric loads, which helps to improve the stability and reliability of the processing process.

[0023] In this embodiment, if Figure 4 As shown, the eccentric support portion 6 is L-shaped, and the second end of the eccentric support portion 6 is provided with a slot 61 adapted to the support block 5, and both sides of the slot 61 are provided with through holes 62 matching the hinge pin 7, which is convenient for installation and accurate positioning.

[0024] In this embodiment, if Figure 2-3 As shown, the mounting base 1 is provided with a mounting hole 11 adapted to the support cylinder 3, and the bottom of the mounting base 1 is located directly below the mounting hole 11 and is provided with an oil inlet hole 12 and an oil outlet hole 13 connected to the internal oil circuit of the support cylinder 3 so as to be connected to the internal oil circuit of the support cylinder 3.

[0025] In this embodiment, if Figure 5 As shown, a bottom cover 2 is detachably provided at the bottom of the mounting base 1, and an oil inlet passage 21 communicating with the oil inlet hole 12 and an oil outlet passage 22 communicating with the oil outlet hole 13 are provided inside the bottom cover 2, ensuring that the oil inlet hole and the oil outlet hole at the bottom of the mounting base are communicated.

[0026] In this embodiment, if Figure 2 As shown, a first sealing ring 14 is provided at the bottom of the mounting hole 11 and around the oil inlet hole 12 and the oil outlet hole 13 to ensure that the oil circuit is sealed and prevent leakage.

[0027] In this embodiment, if Figure 3 As shown, a second sealing ring 15 is provided at the bottom of the oil inlet hole 12 and the bottom of the oil outlet hole 13 to ensure that the oil circuit is sealed and prevent leakage.

[0028] In this embodiment, if Figure 6 As shown, the support cylinder 3 is inserted into the mounting hole 11, and the mounting base 1 and the bottom cover 2 are continued to be installed together. The support head 4 is fixed at the upper end of the support cylinder 3, and the slot 61 of the eccentric support part 6 is clamped on the outer side of the support block 5. The hinge pin 7 is inserted into the through hole 62 and the support block 5, so that the eccentric support part 6 can rotate around the hinge pin 7 and overlap above the support head 4 of the support bar 3, and the protrusion 63 abuts the lower surface of the product. In actual application, the oil cylinder drives the clamping block to press the product. Under the action of the support cylinder 3, the eccentric support part 6 can rotate around the hinge pin 7, and the protrusion 63 can move up and down to support the product to prevent the clamping block from crushing the product.

Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
