Problems solved by technology
In the existing CNC floor milling and boring machines, most of them adopt the clamping method of hydraulic clamping and hydraulic loosening. For example, Chinese patent CN2513714Y discloses an integral machine tool spindle oil cylinder clamping device. In the cavity, the oil hole on the spindle and the central oil hole are connected with the front spindle oil cylinder, but this structure requires the machine tool to move at a relatively slow speed, which cannot meet the requirements of fast response and higher precision of modern machine tools

Embodiment Construction
[0019] The present invention will be further described below in combination with principle diagrams and specific operation examples.
[0020] Such as figure 1 As shown, the floor boring guide rail clamping device of the present invention is used to clamp the column guide rail 00, and specifically includes a clamping body, which includes two clamping plates 1, and the clamping plate 1 is clamped toward the direction of the clamped guide rail. On the surface, a shaft 2 runs through the workbench clamping device of the present invention in a direction perpendicular to the plane where the clamping surface is located. One end of the shaft 2 is fixedly connected with a hydraulic cylinder 3 through a lock nut, and a lock is also sleeved on the other end. Tighten the nut 8. A pressing plate 4 is respectively arranged on the opposite side of the respective clamping surfaces on the two clamping plates 1, specifically, in this preferred embodiment, the two pressing plates 4 are all sphe...

The invention discloses a floor boring lead rail clamping device, which comprises a clamping body, wherein the clamping body comprises two clamping plates; a clamping surface is in a direction of the clamping plates towards the clamped lead rail; a shaft penetrates a workbench clamping device in a direction vertical to the plane of the clamping surface; one end of the shaft is connected with a hydraulic cylinder and a lock nut is sleeved on the other end of the shaft; a pressure plate is respectively arranged at one side opposite to the clamping surface on each of the two clamping plates; the clamping device is fixed on a spindle box through a support, and an elastic component is respectively arranged between the two clamping plates and the shaft. According to the floor boring lead rail clamping device disclosed by the invention, the processing efficiency and the bearing capability of a machine tool are increased; a hydraulic clamping mode is adopted; a disc spring is used to loosen; the structure is compact and the clamping is stable and reliable.
Description
technical field [0001] The invention relates to the technical field of clamps in machining, in particular to a clamping device for a floor boring guide rail. Background technique [0002] In recent years, with the country's increasing investment in the aerospace and energy industries, the requirements for the speed and precision of the machine tool industry are getting higher and higher, which also puts forward higher requirements for the clamping and positioning of moving parts on the machine tool. requirements. When the CNC floor milling and boring machine is processing the workpiece, the stability of the spindle box is very important, which directly affects the accuracy of the workpiece, which requires the design of a simple and compact structure, stable and reliable clamping, easy to operate, safe, economical and practical. clamping mechanism. In the existing CNC floor milling and boring machines, most of them adopt the clamping method of oil pressure clamping and oil ...
