Description

Technical Field

[0001] This utility model relates to a support rod structure, and more particularly to a floating support rod with adjustable pressure and adjustable length. Background Technology

[0002] In mechanical transmission products, there are a large number of thin-walled, irregularly shaped parts. These parts require high precision, but due to their complex shapes and poor rigidity, they are prone to deformation during processing, making it impossible to produce qualified products. For example... Figure 2 As shown, the I-beam structure is a common part design structure. The upper and lower surfaces in the figure have strict form and position tolerance requirements. In actual machining, due to the poor rigidity of the I-beam structure, when the tool is machining the upper (or lower) surface, the upper (or lower) surface is in a suspended state and will produce elastic deformation. Once the tool leaves the machining surface, the upper (or lower) surface will spring back, causing the part to exceed the tolerance. Utility Model Content

[0003] The purpose of this invention is to provide a floating support rod with adjustable pressure and length. When machining parts, the elastic support rod is "supported" against the suspended structure of the part, providing pre-existing elastic support to enhance the rigidity of the part and prevent elastic deformation during machining.

[0004] The technical solution of this utility model is as follows: a floating support rod with adjustable pressure and adjustable length, including a base, a threaded hole on the base, an elastic support rod threaded into the threaded hole, and an "S"-shaped structure on the elastic support rod, the "S"-shaped structure being composed of multiple notches arranged in an upper and lower staggered manner.

[0005] In the aforementioned floating support rod with adjustable pressure and adjustable length, the "S"-shaped structure is located at the middle section of the elastic support rod.

[0006] In the aforementioned floating support rod with adjustable pressure and adjustable length, the "S"-shaped structure is composed of two notches that are staggered upwards and downwards.

[0007] In the aforementioned floating support rod with adjustable pressure and adjustable length, a locking nut is threaded onto the elastic support rod above the base.

[0008] The beneficial effects of this utility model are as follows: Compared with the prior art, the advantages of this utility model are its simple structure, consisting of only three parts, adjustable elastic force, and controllable length by adjusting the thread engagement length between the elastic support rod and the base, making it suitable for various parts. When machining parts, the elastic support rod is "supported" against the suspended structure of the part, providing pre-existing elastic support, which enhances the rigidity of the part and prevents elastic deformation during processing.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0015] An embodiment of this utility model: A floating support rod with adjustable pressure and adjustable length includes a base 1, a threaded hole 2 on the base 1, an elastic support rod 3 threadedly connected to the threaded hole 2, and an "S"-shaped structure on the elastic support rod 3, the "S"-shaped structure being composed of multiple notches 4 arranged in an upper and lower staggered manner.

[0016] In the structure of this utility model, the elastic support rod 3 is the main component that provides elastic force. The elastic support rod 3 has an "S" shape, which provides support force while ensuring that the elastic support rod 3 has a certain elastic floating. The base 1 has a threaded hole 2, which is connected to the elastic support rod 3 by a threaded connection, and the length of the entire floating support rod is controlled by the length of the thread engagement.

[0017] The "S"-shaped structure is positioned at the middle section of the elastic support rod 3 to prevent it from being screwed into the threaded hole 2 during the height adjustment of the elastic support rod 3. At the same time, the "S"-shaped structure, positioned at the upper middle section of the elastic support rod 3, also makes it easier for the elastic support rod 3 to exhibit elastic floating.

[0018] The “S”-shaped structure consists of two notches 4 that are staggered upwards and downwards, one notch 4 is set from left to right and the other notch 4 is set from right to left, ensuring that the elastic support rod 3 itself has good structural strength.

[0019] A locking nut 5 is threaded onto the elastic support rod 3 above the base 1. The locking nut 5 is used to lock the base 1 to ensure that the elastic support rod 3 and the base 1 do not loosen during operation.

[0020] During use, first tighten the locking nut 5 onto the elastic support rod 3, then tighten the base 1 onto the elastic support rod 3, place the entire floating support rod at the position where the part needs to be supported, and adjust the engagement length of the base 1 and the elastic support rod 3 to tighten the floating support rod against the part and form a certain elastic force. Then tighten the locking nut 5 onto the base 1 to lock the base 1 and the elastic support rod 3.

[0021] The elastic force of the elastic support rod 3 is adjustable. It can be controlled by adjusting the dimensions of the "S"-shaped structure on the elastic support rod 3, specifically by controlling the distance t2 between the upper and lower notches 4, and the distance t1 from the bottom of the notch 4 to the outer periphery of the elastic support rod 3. For example, when the distance t2 between the upper and lower notches 4 is smaller, the elastic float of the elastic support rod 3 is relatively larger, resulting in a larger elastic force; conversely, when the distance t1 from the bottom of the notch 4 to the outer periphery of the elastic support rod 3 is closer, the elastic float of the elastic support rod 3 is relatively larger, resulting in a larger elastic force. Alternatively, the elastic force can be adjusted by controlling the thread engagement length between the elastic support rod 3 and the base 1 after it is placed on the workpiece.
