Abstract
The invention discloses a tool for drilling central holes of a steering knuckle arm, comprising a pedestal and a support, the pedestal is provided with a fixing hole, the support is vertically installed with the pedestal, the support is provided with an upper V-shaped block and a lower V-shaped block directly below the upper V-shaped block, and the pedestal is provided with a location device. The upper V-shaped block and the lower V-shaped block are same in size and have accordant V-shaped openings. The location device is a flute located on the pedestal. The location device is a conic tip fixed on the pedestal. The tool provided by the invention is accurate in location, centers of the central holes of two ends are in same straight line, so that axiality is ensured, and products discarding caused by axiality error is eliminated; the tool is simple and practical, convenient in operation and high in processing efficiency.
Description
Technical field
The present invention relates to a kind of back processing unit (plant) of knuckle arm, relate in particular to a kind of knuckle arm and hit hole tool.
Background technology
Knuckle arm in use; often need be on knuckle arm centering; and in traditional technology; the centre bore of knuckle arm relies on operating personnel's experience; use drill bit to carry out centering; the position that occurs centre bore through regular meeting is inaccurate; perhaps the axis of the centre bore at two ends is not on same straight line; thereby cause surplus inequality in process; can cause product rejection too greatly because of the misalignment of axe of the centre bore at two ends when serious; not only inefficiency has also caused the waste of material.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome technological deficiency recited above, to provide knuckle arm to hit hole tool
In order to solve technical problem recited above, the present invention takes following technical scheme.
Provide a kind of knuckle arm to hit hole tool, include base and bearing, described base is provided with fixing hole, and described bearing is vertical with base to be installed, described bearing is provided with V-block and is positioned at following V-block under the V-block, and described base is provided with positioner.
Wherein, described upward V-block is big or small identical with following V-block, and both V-type opening unanimities.
Described positioner is the groove that is arranged on the base.
Described positioner is the cone centre that is arranged on the base.
During use, the first step: base is fixed on the drilling machine, by last V-block, down V-block and groove 4 restrictions need hit the moving and rotation, the rotation of Y direction and the rotation of Z direction of knuckle arm directions X in hole, the drill bit of drilling machine and groove have limited moving of Z direction jointly.The problem of the less and production efficiency of the force rate when considering drill centers.Only with hand pushes away to the Y negative direction in practical operation, so not only can limit the six-freedom degree of workpiece but also has improved drilling efficiency greatly.
Second step: hole-drilled that turned around put then, owing to beaten what a hole when the first step, so that end that will have openning hole positions more convenient and accurate with cone centre, and the axis of centre bore of guaranteeing two ends is on same straight line.
Tool locating provided by the invention is accurate, and the center of two ends centre bore has guaranteed axiality on same straight line, has eliminated because the product rejection that coaxiality error causes; This frock is simple and practical, easy to operate working (machining) efficiency height.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is an another kind of structural representation of the present invention.
Fig. 3 is a kind of structural representation of knuckle arm that hits behind the hole.
Fig. 4 is the another kind of structural representation of knuckle arm that hits behind the hole.
Among the figure, 1. base, 2. bearing, 3. go up V-block, 4. descend V-block, 5. groove, 6. cone centre, 7. fixing hole, 8. knuckle arm, 9. centre bore.
The specific embodiment
See also Fig. 1, knuckle arm hits hole tool and includes base 1 and bearing 2, base 1 is provided with fixing hole 7, bearing 2 and base 1 vertical installation, bearing 2 is provided with V-block 3 and is positioned at following V-block 4 under the V-block 3, base 1 is provided with positioner, and this positioner is the groove 5 that is arranged on the base; Last V-block 3 is big or small identical with following V-block 4, and both V-type opening unanimities.
See also Fig. 2, as shown in the figure, knuckle arm hits hole tool and includes base 1 and bearing 2, base 1 is provided with fixing hole 7, bearing 2 and base 1 vertical installation, bearing 2 is provided with V-block 3 and is positioned at following V-block 4 under the V-block 3, and base 1 is provided with positioner, and this positioner is the cone centre 6 that is arranged on the base; Last V-block 3 is big or small identical with following V-block 4, and both V-type opening unanimities.
In use, normally frock shown in Figure 1 and frock shown in Figure 2 are cooperated use.
During use, the first step: base is fixed on the drilling machine by fixing hole, by last V-block, down V-block and groove 4 restrictions need hit the moving and rotation, the rotation of Y direction and the rotation of Z direction of knuckle arm directions X in hole, the drill bit of drilling machine and groove have limited moving of Z direction jointly.The problem of the less and production efficiency of the force rate when considering drill centers.Only with hand pushes away to the Y negative direction in practical operation, so not only can limit the six-freedom degree of workpiece but also has improved drilling efficiency greatly.
Second step: hole-drilled that turned around put then, owing to beaten what a hole when the first step, so that end that will have openning hole positions more convenient and accurate with cone centre, and the axis of centre bore of guaranteeing two ends is on same straight line.
In order to save the cost of equipment, frock shown in Figure 1 and frock shown in Figure 2 can be fixed on the workbench of same drilling machine successively, so only need the workbench of mobile drilling machine just to can be implemented in the processing of finishing different station on same the machine, promptly finish the processing of workpiece two ends centre bore.
The knuckle arm that processes as shown in Figure 3 and Figure 4, the axis of the centre bore 9 at the two ends of knuckle arm 8 is on same straight line.
