Embodiment Construction
[0011] As shown in the drawings, the present invention includes a base 1, a linear guide rail 9 is provided above the base 1, and guide rail pressing blocks 11 are provided on both sides of the linear guide rail 9, and the guide rail pressing blocks 11 are fixed on the base 1, and the slide plate 4 matched with the linear guide rail 9 A knife seat 2 is attached to the top, a rail stopper 8 is provided at the end of the linear guide rail 9, a shield 5 is provided above the slide plate 4, a dust-proof ring 3 is provided at the end of the slide plate 4, a grating ruler 6 is installed at one end of the slide plate 4, and a base 1 One end is provided with a reading head 7 .
[0012] The linear guide 9 is a retainer-type linear guide. Using a linear guide rail with a cage, there is no collision between the steel balls. At the same time, the steel balls are guided by the cage and arranged in the direction of circulation. The movement is smooth and smooth and stable in a short stroke....

The invention discloses a high-frequency-response micro-feeding servo tool rest driven by double linear motors, which comprises a base. Linear guide tracks are arranged above the base, guide track press cakes are disposed on two sides of the linear guide tracks and fixed onto the base, a tool apron is connected onto a slide plate matching with the linear guide tracks, guide track check blocks are arranged at ends of the linear guide tracks, a shield is arranged above the slide plate, a dustproof ring is disposed at the end of the slide plate, a grating bar is mounted at one end of the slide plate, and a reading head is disposed at one end of the base. The high-frequency-response micro-feeding servo tool rest is used for high-precision non-circular machining, high-frequency-response reciprocation can be realized, requirements of non-circular machining with short strokes can be met, and particularly machining of convexity-variable elliptical piston lines can be realized. Compared with the prior art, the high-frequency-response micro-feeding servo tool rest has the advantage that transmission precision and stability are effectively improved.
Description
technical field [0001] The invention relates to a tool holder for a numerically controlled lathe, in particular to a tool holder which can be used for high-precision non-circular processing. Background technique [0002] At present, there are mainly two methods for turning complex shaped surfaces: hard profiling method and soft profiling method (that is, CNC machining method). Hard profiling processing is to coaxially install the female master with the same piston shape on the main shaft of the machine tool, and then use the profiling device to manufacture the piston with the same shape as the female master. Soft prototyping is to program according to the profile of the piston, and use the compiled program as a model, and use a variety of high-response micro-displacement feed mechanisms of the computer to control the tool to process the piston. A variety of micro-feed servo tool holders have been developed at home and abroad, such as electro-hydraulic servo type, electromag...
