Abstract
The utility model discloses a screw tape grinder which comprises a ball screw device and a manual shaft connecting device. The manual shaft connecting device comprises a handwheel and a shaft lever connected with the handwheel, the ball screw device comprises a ball screw, one end of the ball screw is connected with the shaft lever through a coupler, and the other end of the ball screw is connected with an output shaft of a computerized numerical control (CNC) motor through a coupler. The screw tape grinder is designed into a double-section type, one section of the screw tape grinder is the ball screw device, the other section of the screw tape grinder is the manual shaft connecting device, the shaft lever is connected with the ball screw through the coupler, and therefore the length of the ball screw playing a role of guiding is shortened, deviation is reduced, the precision of guiding is improved, and meanwhile the production cost is saved.
Description
Technical field
The utility model relates to the numerical controlled machinery field, is specifically related to a kind of tap-grinding machine.
Background technology
Tap-grinding machine (being called for short the screw tap mill) is the nucleus equipment of screw tap processing, is used for the threaded portion of grinding screw tap.Tap-grinding machine is a kind of screw tap special purpose grinder that external thread grinder is derived, and mainly satisfies screw tap and adds the high and requirement easy and simple to handle of production efficiency in man-hour.
Metering reference data on the X-direction of tap-grinding machine is take ball screw as reference data.According to " Abbe's principle ", operating point and application point should be on the same straight line, otherwise just can cause error.Design of length with guiding mechanism when the structure of design tap-grinding machine becomes greater than more than three times of emery wheel side-play amount.Will inevitably cause like this length of ball screw longer, so that produce the precision of deviation effects guiding between the operating point of guiding and the application point.Ball screw is expensive simultaneously, and long ball screw has also improved the cost of tap-grinding machine, has strengthened the difficulty of mounting process.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of tap-grinding machine, its objective is, shorten the length of ball screw in whole guider, improve the precision of guiding, reduce the production cost of tap-grinding machine.
For achieving the above object, the technical solution of the utility model is as follows:
Tap-grinding machine, it comprises ball screw device and manual spindle assembling device, described manual spindle device comprises handwheel and the axostylus axostyle that is connected with handwheel; Described ball screw device comprises ball screw, and ball screw one end is connected the other end by shaft coupling and is connected with the output shaft of numerical-control motor by shaft coupling with axostylus axostyle.
Preferably, described shaft coupling is the zero-clearance shaft coupling.
By technique scheme, the beneficial effect that the utility model is obtained is, tap-grinding machine is designed to two-part, and one section is that another section of ball screw device is manual spindle device, and axostylus axostyle connects by shaft coupling with rolling lead screw.The length that has shortened like this ball screw that play the guiding role has reduced deviation, has improved the precision of guiding, has saved simultaneously production cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment tap-grinding machine.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and the specific embodiment the utility model is described in further detail.
Present embodiment as described in Figure 1, tap-grinding machine, it comprises ball screw device and manual spindle device, described manual spindle device comprises handwheel 1 and the axostylus axostyle 2 that is connected with handwheel; Described ball screw device comprises ball screw 3, and ball screw 3 one ends are connected the other end by shaft coupling 4 and are connected with the output shaft of numerical-control motor 6 by shaft coupling 5 with axostylus axostyle 2, and described shaft coupling 4 and shaft coupling 5 are the zero-clearance shaft coupling.
During work, rotate handwheel 1 and promote axostylus axostyle 2 to the motion of shaft coupling 4 directions so that axostylus axostyle 2 is connected by shaft coupling 4 with ball screw 3.Start numerical-control motor 6, the output shaft of numerical-control motor 6 drive by shaft coupling 5 that ball screws 3 rotate so that machine tool body in the motion of ball screw 3 directions and then promote the motion of grinding machine bed body.In the present embodiment, tap-grinding machine is designed to two-part, one section is that another section of ball screw device is manual spindle device, and axostylus axostyle 2 connects by shaft coupling 4 with rolling lead screw 3.The length that has shortened like this ball screw 3 that play the guiding role has reduced deviation, has improved the precision of guiding, has saved simultaneously production cost.
Above-described only is preferred embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. a tap-grinding machine is characterized in that, it comprises ball screw device and manual spindle assembling device, and described manual spindle device comprises handwheel and the axostylus axostyle that is connected with handwheel; Described ball screw device comprises ball screw, and ball screw one end is connected the other end by shaft coupling and is connected with the output shaft of numerical-control motor by shaft coupling with axostylus axostyle.
