Description

一种内腔装配可调定位距An adjustable positioning distance for inner cavity assembly

技术领域 technical field

本发明涉及一种结构件内腔装配的定距设备。The invention relates to a distance-fixing device for inner cavity assembly of structural parts.

背景技术 Background technique

液压挖掘机的动臂体、斗杆体等框体零件在装配时均要保证其内腔的设计尺寸，以保证其达到设计的截面载荷。目前，在装配动臂体、斗杆体时多采用固定定距杆的方式来保证框体内腔的尺寸。但是由于框体的两侧受到装焊模具定位装置的约束，某处的内腔实际尺寸已小于设计的尺寸，而固定定距杆的长度是与内腔的设计尺寸一致的，这就导致了放置固定定距杆的困难。需取出固定定距杆时，又面临固定定距杆难以取出的情况，这时往往需要使用铁锤、钢棍等物体来敲打固定定距杆使其脱落。此操作过程费时、劳动强度较大，并有一定的安全隐患。The frame parts such as the boom body and the stick body of the hydraulic excavator must ensure the design size of the inner cavity during assembly to ensure that it reaches the designed section load. At present, when assembling the boom body and the stick body, the method of fixing the distance rod is often used to ensure the size of the inner cavity of the frame. However, because the two sides of the frame are constrained by the positioning device of the welding mold, the actual size of the inner cavity somewhere is smaller than the designed size, and the length of the fixed distance rod is consistent with the designed size of the inner cavity, which leads to Difficulty in placing fixed distance rods. When needing to take out the fixed distance rod, the situation that the fixed distance rod is difficult to take out is faced again. At this time, objects such as iron hammers and steel rods often need to be used to knock the fixed distance rod to make it fall off. This operation process is time-consuming, labor-intensive, and has certain potential safety hazards.

发明内容 Contents of the invention

本发明的目的在于提供一种可以快速、简单、安全的内腔定距装置，以便解决上述内腔定距困难，劳动强度大，存在安全隐患的问题。The purpose of the present invention is to provide a fast, simple and safe inner cavity spacing device, so as to solve the problems of difficulty in spacing the inner cavity, high labor intensity and potential safety hazards.

本发明的技术解决方案是这样的：一种内腔装配可调定位距，包括：定距主座(1)、定距螺母(2)、定距顶座(3)、平垫圈(4)、螺栓(5)。The technical solution of the present invention is as follows: an inner cavity assembly with adjustable positioning distance, including: distance main seat (1), distance nut (2), distance top seat (3), flat washer (4) , Bolt (5).

本发明的优点是：定距主座(1)、定距顶座(3)为分体式连接结构，两者之间的距离可通过定距螺母(2)、螺栓(5)自由调节，适应框体内腔的实际距离，并能保证框体的内腔设计尺寸，实现定位距的快速、轻松安装、拆卸，而且结构简单、成本低廉、效果明显、适用性好。The advantages of the present invention are: the fixed-distance main base (1) and the fixed-distance top base (3) are split-type connection structures, and the distance between them can be freely adjusted by the fixed-distance nut (2) and the bolt (5). The actual distance of the inner cavity of the frame can ensure the design size of the inner cavity of the frame, and realize the fast and easy installation and disassembly of the positioning distance, and the structure is simple, the cost is low, the effect is obvious, and the applicability is good.

附图说明 Description of drawings

本发明的结构构成是这样的：Structural composition of the present invention is such:

图1是本发明的外观图。Fig. 1 is the external view of the present invention.

图2是本发明的局部剖视图。Fig. 2 is a partial sectional view of the present invention.

图3是本发明的应用示意图。Fig. 3 is a schematic diagram of the application of the present invention.

图1至图3中：定距主座(1)、定距螺母(2)、定距顶座(3)、平垫圈(4)、螺栓(5)。Among Fig. 1 to Fig. 3: fixed distance main seat (1), fixed distance nut (2), fixed distance top seat (3), flat washer (4), bolt (5).

具体实施方式 Detailed ways

本发明的最佳实施例是这样的，参照图1至图3，The preferred embodiment of the present invention is like this, with reference to Fig. 1 to Fig. 3,

根据框体的内腔实际尺寸的大小，旋动定距螺母(2)使定距主座(1)、定距顶座(3)的长度小于框体的内腔实际尺寸，再把本发明放置到需要定距的内腔位置。选好放置位置后，再旋动定距螺母(2)使定距主座(1)、定距顶座(3)的长度变长并使其达到内腔的设计尺寸，顶住框体侧板，保证框体的内腔设计尺寸。装配完成后，再旋动定距螺母(2)使定距主座(1)、定距顶座(3)的长度变小，本发明的长度小于框体内腔设计尺寸后可轻松、方便取出。According to the size of the actual size of the inner cavity of the frame body, turn the distance nut (2) to make the length of the fixed distance main seat (1) and the fixed distance top seat (3) less than the actual size of the inner cavity of the frame body, and then the present invention Place it in the inner cavity where the distance needs to be fixed. After selecting the placement position, turn the spacer nut (2) to lengthen the length of the spacer main seat (1) and the spacer top seat (3) to reach the design size of the inner cavity and withstand the side of the frame plate to ensure the design size of the inner cavity of the frame. After the assembly is completed, turn the distance nut (2) to make the length of the distance main seat (1) and the distance top seat (3) smaller. The length of the present invention is less than the design size of the inner cavity of the frame and can be easily and conveniently taken out .
