Description

Guide rail boring grab Technical Field The utility model relates to the technical field of guide rail drilling clamps, in particular to a guide rail drilling clamp. Background In the prior art, the guide rail drilling clamp is used as important auxiliary tool equipment in machining, the design quality and the functionality of the guide rail drilling clamp directly influence the accuracy and the production efficiency of guide rail drilling, however, the guide rail drilling clamp in the prior art has a plurality of technical problems to be solved, in the practical application process, the guide rail is generally not convenient to thoroughly clamp and fix, most of the design schemes generally only fix one side of the guide rail, the guide rail cannot be clamped in all directions, the guide rail is easily subjected to fine displacement or vibration in the drilling process by adopting the single-side fixing mode, the drilling accuracy and the position accuracy are seriously influenced, and more importantly, when a drill bit applies pressure, the guide rail fixed on one side possibly has tilting or shifting phenomena, the drilling angle deviation and the aperture are irregular, even workpiece damage or safety accidents are possibly caused due to the fact that the fixing is unstable, in addition, the pressure distribution of the single-side fixing mode on the guide rail surface is uneven, the guide rail deformation or surface damage is possibly caused by long-term use, the service life and the product quality of the guide rail are reduced, and the adverse effect on the whole machining quality and the production efficiency is finally brought. In addition, although the part of the improved device in the prior art tries to compress the guide rail onto the base through the movable block, the pressing block and other parts of the cylinder, the fixing effect is improved to a certain extent, but the design still has obvious limitations, in practical application, according to the processing requirements of different working conditions and different specifications of guide rails, the length or thickness of the movable block is often required to be replaced and adjusted so as to adapt to different workpiece sizes and processing requirements, however, the movable block mounting and dismounting operation of the device is usually complicated in design, auxiliary operation is required to be carried out by means of a plurality of tools such as a special spanner, an inner hexagonal spanner and the like, the dismounting process is tedious and time-consuming, the whole process may need to consume a great deal of time and physical effort, especially in the production environment of mass and multi-variety processing, the complicated movable block replacement operation seriously reduces the production efficiency, increases the labor intensity and fatigue degree of workers, the inconvenient realization of the design for conveniently replacing the movable block becomes an important factor for restricting flexible application and efficiency improvement of the guide rail drilling clamp, and the remarkable adverse effect is brought to capacity and cost control of a production line.
