Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a centering device for guide rail machining. Background Art

[0002] A guide rail is a groove or ridge made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. A guide rail, also known as a slide rail, linear guide, or linear slide, is an upgraded version of a linear bearing bracket used in linear reciprocating motion situations. It has a higher rated load than traditional linear bearings and can withstand a certain torque. It can achieve high-precision linear motion under high load conditions. During the guide rail processing process, the guide rail needs to be centered to facilitate subsequent processing and production.

[0003] Chinese patent number CN219379757U discloses an elevator guide rail bracket processing and centering mechanism, including a base and a stabilizing structure, wherein a clamping block is installed on the top of the base, and the stabilizing structure is installed on the top of the base and the top of the clamping block; the stabilizing structure includes a limit frame, the bottom of the limit frame is fixed with bolts to the clamping block, a through hole is opened inside the limit frame, a telescopic rod passes through the through hole, a telescopic spring is sleeved on the outside of the telescopic rod, and rubber blocks are bonded to the left and right sides of the telescopic rod; pads are bonded to the left and right sides of the slide groove; the top structure of the movable block and the top structure of the fixed block have the same symmetrical structural distribution.

[0004] During use of the above-mentioned equipment and the equipment on the market, an electric telescopic rod is generally used to drive the movable block to move, and during the displacement of the movable block, the slider slides flexibly in the slide groove, so that the device can fix the material and the device can be freely adjusted according to the size of the material, thereby improving the practicability and promotion of the device.

[0005] However, in the process of operation and use of the above-mentioned equipment on the market, the movable block is usually driven to move by an electric telescopic rod. However, in the process of use of such a structure, the electric telescopic rod is exposed to the outside and the device can only drive one of the clamping blocks to move, thereby reducing the effect of material clamping and fixing during the material fixing process. The electric telescopic rod is exposed to the outside, which reduces the service life of the electric telescopic rod and reduces the practicability and promotion of the device. Therefore, it is urgent to design a centering device for guide rail processing to solve the above problems. Utility Model Content
