Problems solved by technology

Time-consuming and not intuitive
[0005] Especially in the process of driving two tool holders at the same time on the horizontal and vertical saddles driven by a screw rod, after changing the tool of a certain tool position on a certain tool holder, it is impossible to adjust and modify the NC program for tool setting.

Embodiment Construction

[0027] figure 1 Among them, the four tool positions are distributed on the four sides of the tool holder body.

[0028] figure 2 Among them, each tool position body (3) is contained in the structure mode on the tool rest body (1). The special screw (5) fixes the guide rail (6) on the tool holder body (1), the sliding gap between the guide rail (6) and the inner surface of the tool position body (3) is adjusted by the relative rotation angle of the eccentric sleeve (9), and the outer surface The sliding gap is adjusted by the insert (7). After the adjustment is appropriate, the guide rail (6) is fixed vertically and laterally by the special screw (5) and the adjustment screw (8), so that the knife position body (3) can move in a straight line. play a guiding role. The hollow part of the tool holder body (1) is the interface between the tool holder indexing mechanism and the electric tool holder indexing mechanism of a general-purpose lathe. An ordinary general-purpose lath...

Abstract

The invention discloses a millesimal fine adjustment tool rest, which is characterized in that the cutter locations at all directions of the tool rest have independent functions of adjustment and tool setting, the reading value precision per division is 0.0005mm, and the travel route is 0-8mm. The cutter locations rotate around a middle rotary mechanism together to change positions, thus being capable of being located on arbitrary angles. The interface in the middle of the tool rest is matched with a mechanical indexing mechanism and an electrodynamic type indexing mechanism of an ordinary universal lathe. A mechanical indexing mechanism of an ordinary universal lathe tool rest is installed in the interface to form a mechanical manual millesimal fine adjustment tool rest. An electrodynamic indexing mechanism is installed in the interface to form an electrodynamic indexing millesimal fine adjustment tool rest.

Description

Technical field [0001] The invention belongs to the field of tool rests for clamping tools of numerically controlled lathes and general-purpose lathes. Background technique [0002] At present, the electric rotary tool holders and manual mechanical rotary tool holders used on CNC lathes and general-purpose lathes do not have the function of independently adjusting and setting each tool clamped on the tool holder. Instead, the rotation of the lead screw under the horizontal and vertical saddles drives the horizontal and vertical saddles to move linearly, and at the same time pushes the tool holders mounted on the horizontal and vertical saddles to move linearly to complete tool adjustment and tool setting. [0003] The feeding accuracy of the screw on the general-purpose lathe is 100 grades, and the reading value of each engraved line is 0.02. To achieve the feeding accuracy of 1,000 grades, it is necessary to rely on auxiliary measuring tools and the experience of the operat...
