Description
Technical field
The utility model relates to a kind of machinofacture unit clamp, the specifically Special drill jig of a kind of brake valve housing upper surface centre hole.
Background technology
On lathe during processing work, in order to make workpiece the surface energy that this operation is processed reach the dimensions that pattern specifies, geometrical shape and and other surfaces between the technical requirements such as mutual position, before starting lathe, it is necessary to first workpiece is filled good folder jail. In mechanical workout, on lathe in order to determine the location of workpiece and the tooling clamped is called lathe fixture.
Unit clamp is the special purpose device of certain the procedure processing request for a certain workpiece and specialized designs, manufacture. It is generally use in product batch production processing, is a kind of lathe fixture that engineering works' number of applications is maximum, is the fixture just adopted when using universal machine fixture to be difficult to ensure that product parts working accuracy and production quantity are bigger.
Boring fixture is mainly used in the processing in workpiece surface hole, primarily of location element, gripping unit, induction element and clamp body composition. For the workpiece needing hole machined, clamping, location and guiding creating a great impression to its working accuracy.
The boring fixture used in the past is often attended by installing/dismounting inconvenience, and workpiece not easily presss from both sides jail, operates loaded down with trivial details, and working accuracy and production efficiency all compare low situation.
Summary of the invention
For solving above-mentioned existing problem, the utility model provides the Special drill jig of a kind of compact construction, reliable clamping, brake valve housing upper surface centre hole simple to operate.
For achieving the above object, the technical solution adopted in the utility model is: the Special drill jig of a kind of brake valve housing upper surface centre hole, comprise location element, clamping element, guiding element and clamp body, described clamp body comprises level and vertical portion, described location element comprises setting spindle, and the vertical portion shrink-fit of the left end of setting spindle and clamp body, right-hand member are provided with outside screw; Described clamping element comprises the fitting nut with setting spindle right-hand member thread fit and snap washer; Described guiding element comprises the drill jig plate being positioned at upper end, clamp body vertical portion and the interchangeable drill bushing being enclosed within drill jig plate.
Further, it is provided with lining between described interchangeable drill bushing and drill jig plate.
Further, it is provided with thrust screw on the left of described interchangeable drill bushing.
Further, described setting spindle left end is fixed on the vertical portion of clamp body by nut.
Further, the horizontal part of described clamp body and vertical portion are an entirety.
The utility model compared with prior art, has following useful effect: the utility model clamping is solid and reliable, compact construction, easy and simple to handle, working accuracy and production efficiency are higher, and Special drill jig major part is all standardized component, it is convenient to choose, the achievement of low cost high yield can be obtained.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is brake valve part structural representation of the present utility model;
In figure: 1, interchangeable drill bushing; 2, lining; 3, drill jig plate; 4, thrust screw; 5, snap washer; 6, fitting nut; 7, setting spindle; 8, clamping workpiece; 9, clamp body.
Below in conjunction with the drawings and specific embodiments, structure of the present utility model and location clamping process are described further.
Embodiment
It is front view and the vertical view of the utility model Special drill jig as Figure 1-Figure 2, Fig. 3 is the utility model brake valve part structure iron, i.e. clamping workpiece 8, boring fixture of the present utility model comprises location element, clamping element, guiding element and clamp body 9, clamp body 9 is the base components of fixture, for connecting and fix each element and device on fixture so that it is become as a whole, described clamp body 9 comprises level and vertical portion, and its horizontal part and vertical portion are one-piece construction; Described location element comprises setting spindle 7, the left end of setting spindle 7 and the vertical portion shrink-fit of clamp body 9, and is fixed on the vertical portion of clamp body 9 by nut, and the right-hand member of setting spindle 7 is provided with outside screw; Described clamping element comprises the nut 6 with setting spindle 7 right-hand member thread fit and snap washer 5; Described guiding element comprises the drill jig plate 3 being positioned at upper end, clamp body 9 vertical portion and the interchangeable drill bushing 1 being enclosed within drill jig plate 3, lining 2 also it is provided with between interchangeable drill bushing 1 and drill jig plate 3, lining 2 is fitted in drill jig plate 3, in order to prevent interchangeable drill bushing 1 from sliding up and down or rotating in drill jig plate 3 hole, also it is provided with thrust screw 4 in the left side of interchangeable drill bushing 1.
During use, with setting spindle 7, the clamping workpiece 8 shown in Fig. 3 is fixed on the vertical portion of clamp body 9, determine to fix after well, clamping workpiece 8 is clamped with snap washer 5 and fitting nut 6 on the right side of setting spindle 7, the position of the interchangeable drill bushing 1 of last adjustment in good time, can process the centre hole of clamping workpiece 8 upper surface; The utility model is correct relative to the position between drilling tool and lathe by adopting setting spindle to ensure to add man-hour workpiece, adopts fitting nut and snap washer to make workpiece can keep set position in fixture to process and can carry out smoothly.
Embodiment recited above is only preferred implementation of the present utility model be described, and not design of the present utility model and scope is limited. Under the prerequisite not departing from the utility model design design, the various modification that the technical solution of the utility model is made by the common personnel in this area and improvement, all should drop into protection domain of the present utility model.
