Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The grinding machine of a kind of taper hole as shown in Figure 3, comprise feed mechanism, grinding mechanism and clamping mechanism, described feed mechanism arranges independently two groups, each group feed mechanism comprises the first motor 5, ball screw 14 and driving member 13 and workbench 2, the first described motor 5, ball screw 14 is all for symmetry axis is distributed in support 16 two ends with the axis of grinding machine support 16, be arranged in the feed mechanism of support 16 with one end, be connected and fixed by shaft coupling 15 between described first motor 5 output shaft and ball screw 14, described ball screw 14 and driving member 13 pivot bush unit, described driving member 13 is fixedly connected with workbench 2.Described workbench 2 is positioned at support 16 top, when the first motor 5 drives ball screw 14 rotary motion, ball screw 14 drives driving member 13 to make horizontal rectilinear motion, and actuator 13 drives workbench 2 relative to support 16 also level of synchronization rectilinear motion, thus realizes the feed motion of grinding machine.
Described grinding mechanism also arranges independently two groups, and each group grinding mechanism comprises the second motor 6 and emery wheel 8, two the second motors 6 and is fixedly mounted on respectively independently on workbench 2, and its output shaft is fixedly connected with emery wheel 8 respectively; The central axes of two emery wheels 8 and its grinding face relative thirty years of age, the grinding face of described two emery wheels 8 is the conical surface consistent with the tapering of taper hole to be processed.
Described clamping mechanism to be fixedly mounted on grinding machine support 16 and between two emery wheels 8, particularly, described clamping mechanism forms screw thread by clamping bracket 11 and holding screw 9 and is flexibly connected and forms, described clamping bracket 11 to be fixedly connected on grinding machine support 16 and between two emery wheels 8, clamping bracket 11 is offered installation through hole, the central axes of described installation through hole and two emery wheels 8.
When adopting above-mentioned grinding machine to carry out the grinding of taper hole, concrete operation step is as follows:
First, as shown in Figure 3, workpiece 1 to be processed is installed on clamping bracket 11, then by holding screw 9, workpiece 1 clamping is fixed.In order to ensure that the clamping of workpiece 1 firmly, reliably; and protect workpiece 1 outer surface to be unlikely manufacturing deficiencies such as scratching, damage in Grinding Process; can also increase and lining 10 and holding screw 9 are set; also be that composition screw thread is flexibly connected between described lining 10 and holding screw 9; described lining 10 is arranged in the installation through hole on clamping bracket 11; lining 10 is offered clamping workpiece through hole; the central axes of described clamping through hole and two emery wheels 8; like this, workpiece 1 to be processed can be fixed on lining 10 by clamping.
Then, start two the first motors 5, two workbench 2 moved horizontally to workpiece 1 respectively gradually, until the emery wheel 8 at workpiece 1 two ends go in the same direction respectively near the both ends of the surface of workpiece 1.
Next, start two the second motors 6, emery wheel 8 rotates relative to workpiece 1, and the spinning movement utilizing two emery wheels 8 and the feed motion gone in the same direction cooperatively interact, and can go out taper hole 101, as shown in Figure 4 to workpiece 1 synchronous processing.After machining, the second motor 6 quits work, and regulates the first motor 5 reverse operation of workpiece 1 both sides respectively, makes the emery wheel 8 of workpiece 1 both sides leave workpiece 1 to suitable position, unclamp holding screw 9, takes out workpiece 1.
In the above-mentioned Grinding Process to taper hole 101, in order to ensure the stability of the feed motion of two emery wheels 8, to ensure the machining accuracy of taper hole 101, the first described motor 5 preferably adopts servomotor.Because emery wheel 8 is when grinding, the grinding face of its taper can continuous loss, thus can reduce the machining accuracy of taper hole 101, needs to change qualified forming grinding wheel in time.The conveniently replacing of emery wheel 8, simultaneously, guarantee other workpieces not needing to adjust grinding machine when changing emery wheel 8, emery wheel 8 can be fixedly connected on grinding wheel spindle 7 one end, particularly, in this grinding wheel spindle 7 one end, threaded joints is set, namely described emery wheel 8 forms screw thread by locking nut 12 and grinding wheel spindle 7 and is flexibly connected and is fixedly connected on grinding wheel spindle 7, the other end of described grinding wheel spindle 7 is then fixedly connected with the second motor 6 output shaft, electro spindle is become, as shown in Figure 3, Figure 4 by grinding wheel spindle 7 and spindle motor i.e. the second motor 6 being combined together.Described electro spindle is the one of bistrique, drives emery wheel 8 to make high speed rotary motion.
Consider in Grinding Process, because the ablation force rate between emery wheel 8 and workpiece 1 is comparatively large, therefore, all likely there is axis, radial-play in workpiece 1, emery wheel 8, and this play greatly can reduce the machining accuracy of taper hole 101.For ensureing the machining accuracy of taper hole 101, as shown in Figure 3, Figure 4, in installation through hole on clamping bracket 11, stop bit step can be set, in the clamping workpiece through hole on lining 10, stop bit step is set, axial limiting can be carried out to workpiece 1 well by stop bit step.Simultaneously, when grinding, two the second motors 6 can be set upon actuation, the direction of rotation of two emery wheels 8 is contrary, and like this, the taper hole 101 at workpiece 1 two ends is when grinding, the ablation power that workpiece 1 bears will obtain partial offset, thus effectively can alleviate axial, the radial-play amplitude of workpiece 1, emery wheel 8, be conducive to the machining accuracy improving taper hole 101, ensure that passing rate of processing.
To sum up, due to the central axes of two emery wheels 8, relative thirty years of age of its grinding face, and the grinding face of two emery wheels 8 is the conical surface consistent with the tapering of taper hole 101 to be processed, when carrying out grinding, workpiece 1 to be processed does not rotate in grinding process, just two emery wheels 8 move as horizontal feed with going in the same direction, rotate relative to workpiece 1 simultaneously, to carry out synchronous grinding to the both ends of the surface of workpiece 1 respectively, this form grinding processing mode, only need to carry out disposable clamping operation to workpiece 1, the synchronous processing that can realize workpiece 1 two ends taper hole 101 completes, and the size of taper hole 101 and angle can rely on forming grinding wheel 8 to be ensured.Even if when taper hole 101 specification changes, also only need size required by taper hole 101 and angle, design or choose the forming grinding wheel 8 of the different grinding conical surface, therefore, drastically increase processing and forming efficiency and the machining accuracy of taper hole 101 on workpiece 1, and the axiality of workpiece 1 two ends taper hole 101 can reach 0.01, can meet the axiality requirement of workpiece two ends taper hole 101 completely.Even if size and the angle of the taper hole 101 at workpiece 1 two ends are inconsistent, when adopting grinding machine of the present utility model to carry out the grinding of taper hole 101, its working (machining) efficiency also can improve more than at least 2 times, and the concentricity of workpiece 1 two ends taper hole 101 can control within 0.01.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
