Abstract
The utility model discloses a broaching fixture for machining a valve bush. The broaching fixture comprises a broach, a sliding positioning block device and a spring sheet. The broach is provided with the sliding positioning block device and the spring sheet, the sliding positioning block device is connected with one end of the spring sheet, and the other end of the spring sheet is fixed on the broaching fixture. According to the broaching fixture, a workpiece fixture is provided with a positioning pin to position workpieces, a broach fixture is provided with the sliding positioning device and the spring sheet, so that the broach is positioned in the direction of rotating, the demand of the phase angle between a spline and a datum hole inside an eight groove is guaranteed, machining of first drilling a hole and then broaching is achieved, burrs are reduced, the percent of pass of products and work efficiency are improved, and the broaching fixture for machining the valve bush has good application prospect.
Description
Technical field
The utility model belongs to field of machining, relates in particular to a kind of processing valve pocket broaching fixture.
Background technology
Valve pocket is the strength member of hydraulic booster vehicle steering system, is in the past to adopt to process first eight groove internal splines on broaching machine always, then bores 12 apertures again, the mode of last deburring, and this also is the conventional method of former external this type of part of processing.But after the last processing of totally 12 apertures, the burr that produces on the eight groove spline inwalls is very hard, the cleaning difficult for the 2mm of this part, 3mm.Generally be to remove large burr with push broach first, manually clear up little burr with file again, but be very easy to like this push away bad spline end face and dampen eight groove internal splines surface, scrappage is once up to 1%, and deburred is unclean, and inefficiency is very large on finished product shipment impact.
The utility model content
The purpose of this utility model is to utilize a kind of processing valve pocket broaching fixture, when being intended to solve the burr on the removal eight groove spline inwalls that exist in the existing valve pocket production, easily push away bad spline end face and dampen eight groove internal splines surface, increase the scrappage of product, and deburred is unclean, inefficiency is to the far-reaching problem of finished product shipment.
The purpose of this utility model is to provide a kind of processing valve pocket broaching fixture, and described anchor clamps comprise: broaching tool, slip locating block device and spring leaf; Described slip locating block device and spring leaf are set on the described broaching tool, and described slip locating block device connects an end of described spring leaf, and the other end of described spring leaf is fixed on described anchor clamps.
Further, described slip positioner and spring leaf are located in direction of rotation broaching tool.
Further, the processing mode of described valve pocket is the again broaching machine of holing first.
The processing valve pocket broaching fixture that the utility model provides, the processing of valve pocket is adopted the order of the post-tensioning bed of holing first, by at work piece holder alignment pin being set, workpiece is positioned, at broaching fixture slip positioner and spring leaf are set, broaching tool is positioned, phase angle requirement between eight groove internal splines and the datum hole, guaranteed to hole the first successful implementation of post-tensioning bed, anchor clamps of the present utility model have improved the qualification rate of product, improve operating efficiency, reduced the quantity of burr in producing, had good promotion and application to be worth.
Description of drawings
Fig. 1 is the processing valve pocket that provides of the utility model embodiment with the structural representation of broaching fixture.
Among the figure: 1, broaching tool; 2, slip positioner; 3, spring leaf.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of processing valve pocket broaching fixture, and these anchor clamps comprise: broaching tool, slip locating block device and spring leaf; Slip locating block device and spring leaf are set on the broaching tool, an end of slip locating block device linking springs sheet, the other end of spring leaf is fixed on anchor clamps.
As the prioritization scheme of the utility model embodiment, slip positioner and spring leaf are located in direction of rotation broaching tool.
As the prioritization scheme of the utility model embodiment, the processing mode of valve pocket is the again broaching machine of holing first.
Referring to accompanying drawing 1, the utility model embodiment is processed valve pocket be described in further detail with broaching fixture.
As shown in Figure 1, a kind of valve bush part broaching machine clamp for machining in this example mainly is on broaching tool 1 anchor clamps, is provided with spring leaf 3 and slip locating block device 2, broaching tool 1 has been done the location of direction of rotation, making both normal clampings of broaching tool 1, can guarantee again the phase angle requirement of eight groove internal splines, at first is that workpiece increases the location that rotates on the Z direction, designed an alignment pin at work piece holder, when workpiece put up, alignment pin inserted baseline trough, so just the workpiece rotating direction has been located; Then be that direction of rotation to broaching tool 1 positions, on broaching tool 1 anchor clamps, broaching tool 1 has also been done the location of direction of rotation, utilize spring leaf 3 and slip locating block device 2, make both normal clampings of broaching tool 1, can guarantee again the phase angle requirement of eight groove internal splines, so just determine the phase angle requirement between eight groove internal splines and the datum hole.Thereby make the broaching machine processing successful implementation of holing first again.
The processing valve pocket broaching fixture that the utility model provides, the processing of valve pocket is adopted the order of the post-tensioning bed of holing first, by at work piece holder alignment pin being set, workpiece is positioned, at broaching fixture slip positioner and spring leaf are set, broaching tool is positioned, phase angle requirement between eight groove internal splines and the datum hole, guaranteed to hole the first successful implementation of post-tensioning bed, anchor clamps of the present utility model have improved the qualification rate of product, improve operating efficiency, reduced the quantity of burr in producing, had good promotion and application to be worth.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
