Description

Numerically controlled lathe tool holder height adjusting device

Technical field

The utility model relates to numerically controlled lathe, particularly a kind of tool holder height adjusting device of numerically controlled lathe.

Background technology

On existing numerically controlled lathe, known cutter frame structure has two classes, one class is fixed, do not possess the height regulatory function, if cutter point of a knife height does not overlap with the work centre height, to cause the workpiece processing dimension to can not get guaranteeing and scrapping, so this class knife rest is the height of adjusting knife rest by the mode that adds cushion block between cutter hub and knife rest, obvious this adjustment mode is difficult to control; Another kind of is adjustable, toolmaker lathe as the production of HAAS lathe company, its knife rest is to do main body by the fixing vertical dovetail groove, movably groove is done attached body, between main body, attached body, spur the adjusting height up and down by bolt, because the below does not have supporter, so its intensity and rigidity deficiency, be difficult to guarantee the machining accuracy of workpiece.

The utility model content

Technical problem to be solved in the utility model provides a kind of numerically controlled lathe tool holder height adjusting device, and this adjusting device can not only carry out the tool holder height adjustment easily and fast, and has enough rigidity, helps improving and guaranteeing the machining accuracy of workpiece.

The technical scheme that its technical problem that solves the utility model adopts is: numerically controlled lathe tool holder height adjusting device of the present utility model, comprise knife rest and bed slide, it is characterized in that: be provided with bed slide between described knife rest and the bed body, this bed slide and knife rest have the sliding surface that is wedge shape; Offer the top board that extends along sliding surface on the bed slide, be provided with the guide pad that is subjected to its constraint in the gathering sill, knife rest is connected with guide pad by retaining mechanism.

After taking abovementioned technology, unclamping retaining mechanism makes knife rest move along the gathering sill bearing of trend, can adjust tool holder height easily and quickly, because knife rest is provided with the bed slide that is connected with a body between the body with bed, therefore can make cutter holder device have enough intensity and rigidity, thereby help improving and guaranteeing the machining accuracy of workpiece.

As a kind of preferred version of the present utility model, for improving the accuracy that knife rest is adjusted, and the position that adjusted knife rest is maintained fixed, the lower end at sliding surface on the described bed slide is provided with top board, and the fastening screw that can hold out against knife rest at the gathering sill bearing of trend is installed on this top board.

As another kind of preferred version of the present utility model or to the further improvement of above-mentioned preferred version, for ease of processing with reduce manufacturing cost, the cross section of described gathering sill, guide pad is the T type.

The beneficial effects of the utility model are, can carry out the tool holder height adjustment easily and fast, and have enough rigidity, help improving and guaranteeing the machining accuracy of workpiece; Tool holder height is adjusted the accuracy height, and simple in structure, easily manufactured.

Description of drawings

This specification comprises following three width of cloth accompanying drawings:

Fig. 1 is the structural representation of the utility model numerically controlled lathe tool holder height adjusting device;

Fig. 2 is the cutaway view along A-A line among Fig. 1;

Fig. 1 is the vertical view of the tool holder height adjusting device of the utility model numerically controlled lathe;

Parts, toponym and pairing mark among the figure: knife rest 10, tie down screw 11, bed slide 20, gathering sill 21, guide pad 22, top board 30, fastening screw 31.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, numerically controlled lathe tool holder height adjusting device of the present utility model comprises knife rest 10, is provided with bed slide 20 between described knife rest 10 and the bed body, and this bed slide 20 has the sliding surface that is wedge shape with knife rest 10.Offer the top board 30 that extends along sliding surface on the bed slide 20, be provided with the guide pad 22 that is subjected to its constraint in the gathering sill 21.Knife rest 10 is connected with guide pad 22 by retaining mechanism.Unclamping retaining mechanism makes knife rest 10 move along the bearing of trend of gathering sill 21, can adjust the height of knife rest 10 easily and quickly, because knife rest 10 is provided with the bed slide 20 that is connected with a body between the body with bed, therefore can make cutter holder device have enough intensity and rigidity, thereby help improving and guaranteeing the machining accuracy of workpiece.

With reference to Fig. 1 and Fig. 3, for improving the accuracy that knife rest 10 is adjusted, and the position that adjusted knife rest 10 is maintained fixed, be provided with top board 30 in the lower end of its sliding surface on the described bed slide 20, the fastening screw 31 that can hold out against knife rest 10 at gathering sill 21 bearing of trends is installed on this top board 30.

With reference to Fig. 2, for ease of processing and reduction manufacturing cost, the cross section of described gathering sill 21, guide pad 22 is the T type.With reference to Fig. 1, be the simplified structure of trying one's best, as a kind of typical collocation form, described retaining mechanism can adopt one vertically to pass the tie down screw 11 that knife rest 10 is threaded with guide pad 22.

Some principles of the tool holder height adjusting device of the above the utility model numerically controlled lathe that just explains through diagrams, be not be the tool holder height adjusting device of the utility model numerically controlled lathe to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized, all belong to the utility model in the claim of asking.
