Abstract

The invention relates to a guideway slide type right angle coordinate positioning scriber, comprising a scribing flat plate and a height vernier caliper arranged on the working face of the scribing flat plate. The scriber further comprises a clamp device for clamping a workpiece to be scribed; the clamp device is in a cuboid shape; and the front end surface of the clamp device is provided with a runner which is provided with a bolt capable of sliding inside. When the scriber is used for scribing lines, all accurate machining boundaries can be fast and conveniently scribed at two coordinate directions which are mutually perpendicular only by clamping the workpiece once, and the positioning of the workpiece is accurate. The guideway slide type right angle coordinate positioning scriber doesnot need alignment during scribing, the scribing accuracy totally depends on the manufacture accuracy of the clamp device and has no relation to the alignment process; and the guideway slide type right angle coordinate positioning scriber has the advantages of high scribing accuracy, good repeatability, simple manufacture process and low manufacture cost.

Description

The scriber of guide rail slip type rectangular co-ordinate location

Technical field

The present invention relates to the scriber of a kind of guide rail slip type rectangular co-ordinate location.

Technical background

At mark signature intersection on the end face of disc-like part or on the end face at the plate class part of random profile or when drawing orthogonal parallel lines with regular profile; All want in advance one or at least two datum levels of completion of processing part; Come the disc-like of regular profile or the plate class workpiece of random profile are positioned with this datum level, confirm processing boundary accurately through centering with by means of the method for material again.Operating process is more original, and is also more loaded down with trivial details.

The orientation tool of the end face line of existing disc-like part to regular profile is that v block, magnetic lean on iron and the first-class device of calibration to position line basically, leans on the positioning and marking device of iron for v block, magnetic, though simple in structure; The equipment price is not high yet; Operate also easyly, but it locatees time line ratio of precision to round-disk shape workpiece lower, and centering positions line at least at twice; That is rule is repeated poor for this reason; And just cumbersome for the line of the centering of random profile part, be with first completion of processing first datum level basically and reach the corresponding techniques requirement, again with processing second basis on the basis of this first datum level.And in scratching process, being to buttress disk type work with hand basically, is purpose to reach positioning and locking.And the dividing head positioning and marking device, though workpiece location line precision is high, repeatability rule better by institute, and its technology assembling is complicated, and the equipment price is high, is more than several thousand yuan basically, and operates complicacy.

Summary of the invention

When ruling, need multiple clamping for overcoming prior art; The shortcoming of complicated operation; The invention provides clamping of a kind of need and can mark all right processing boundary, and clamping workpiece is swift in motion conveniently line precision height; Simple to operate, the scriber of the guide rail slip type rectangular co-ordinate location that cost is low.

The scriber of guide rail slip type rectangular co-ordinate location; Comprise streak plate and be placed in the vernier height gauge on the described streak plate working face; It is characterized in that: described scriber comprises that also one clamps the clamp device of workpiece to be crossed; Described clamp device is cuboid, and the front end face of described clamp device has chute, and described chute is provided with a pair of slidably its interior bolt.

Further, the front end face of described clamp device has many chutes, and all chutes meet at same intersection point.

Further, be provided with compress gasket between described chute and the bolt.

Further, the upper side of described clamp device and the depth of parallelism of downside are less than or equal to 0.01mm, and the depth of parallelism of left surface and right flank is less than or equal to 0.01mm.

Further, the perpendicularity of described upper side and left surface or right flank is less than or equal to 0.005mm, and the perpendicularity of described downside and left surface or right flank is less than or equal to 0.005mm.

Further, the perpendicularity of described chute and described front end face is less than or equal to 0.04mm.

Further, each surperficial roughness of described clamp device is 0.8 μ m.

Technical conceive of the present invention is: in clamp device, formed two groups of orthogonal fixed coordinates axles; In scratching process; Only need to duplicate clamping to these two orthogonal fixed coordinates axles on the part on this clamp device, just can mark a series of vertical line and parallel lines.The front end face of clamp device of the present invention has many chutes, and with the position that bolt slides onto and workpiece size to be rule is complementary, the bolt of screwing can be rule to workpiece with clamping work pieces.

During line, with the front end face of parts fixation at clamp device, swivel bolt is with the part locking positioning through bolt; Then; Be placed on this clamp device upper side or downside on the working face of streak plate; Just can mark first processing boundary with vernier height gauge, through the height dimension of adjustment vernier height gauge, just can mark with first processing boundary parallel a series of processing boundary.When drawing with orthogonal second processing boundary of first processing boundary; Turn 90 degrees as long as revolve described clamp device; Just be placed directly in this clamp device left surface or right flank on the streak plate; Just can mark second processing boundary with vernier height gauge, through the height dimension of adjustment vernier height gauge, just can mark with second processing boundary parallel a series of processing boundary.

The present invention is when line, and workpiece is as long as a clamping just can mark all right processing boundary at two orthogonal coordinate directions, and is quick and convenient, and accurate positioning; Need not centering during line, the line precision depends on the accuracy of manufacture of clamp device fully, and is irrelevant with the process of centering, and it is high to have the line precision, the advantage of the good reproducibility of being rule; And manufacturing process of the present invention is simple, and is cheap for manufacturing cost.
