Abstract

A combined fixture for quick positioning marking and detecting of circular shafts comprises a V-shaped frame. The bottom surface of the V-shaped frame is perpendicular to a left side and a right side respectively, a V-shaped groove symmetrical to a central line is arranged on the upper surface of the V-shaped frame, a folded clamping seat is mounted on the upper surface of the V-shaped frame, and the folded clamping seat and the V-shaped groove form an inscribed quadrangle. The combined fixture has the advantages that positioning standard of workpieces to be processed keeps constant, uniform standard is realized, processing precision of parts is high and the parts can be detected conveniently and quickly since the V-shaped frame and the clamping seat are assembled together all the time during process of marking and data detecting of shaft-like parts; the combined fixture has wider applicable range; and further the combined fixture is low in manufacturing difficulty, low in processing cost and simple in maintenance.

Description

Be used for the built-up jig that the circular shaft class is located line fast and detected

Technical field

The utility model relates to a kind of built-up jig that the circular shaft class is located line fast and detected that is used for.

Background technology

Pincers worker is when making part by hand, and it is the part that positioning reference is confirmed size positions with the control form and position tolerance of other machined surfaces that regular meeting runs into the arc surface, shown in Fig. 1-3; Though when line, can use the free degree of V-type frame 1 ' restriction pole class part 2 ' rotation, also can mark its processing boundary; As shown in Figure 4, but when process operation, benchmark uncertain; Detect for processing and bring very big difficulty; As shown in Figure 5, data are inaccurate when making dial gauge 3 ' beat table, thereby have influence on the machining accuracy of part.

Summary of the invention

When ruling in the location and detects, exist datum level uncertain for solving pole class part; Measure inconvenient, inaccurate; The problem that machining accuracy is not high; Provide a kind of datum level to confirm, convenient measurement, quick, accurate, the circular shaft class that is used for that machining accuracy is high is located the built-up jig of ruling and detecting fast.

The technical scheme of the utility model:

Be used for the built-up jig that the circular shaft class is located line fast and detected; Comprise a V-type frame; The bottom surface of said V-type frame is vertical respectively with the and arranged on left and right sides face; Have on the upper surface of said V-type frame one be symmetrical in center line the V-type groove, it is characterized in that: a broken line type deck is installed on the upper surface of said V-type frame, and said deck and V-type groove form quadrangle in.

Further, said deck is connected on the upper surface of said V-type frame through sunk screw.

The bottom surface of the V-type frame of the utility model, each flatness of left and right side are at 0.02mm; The perpendicularity of bottom surface and and arranged on left and right sides face is at 0.01mm.

When the utility model will mark orthogonal processing boundary to circular shaft class part; Be clamped in circular shaft class part between V-type frame and the deck; The bottom surface of V-type frame put with flat board on, vernier height gauge can mark first processing boundary that is parallel to V-type frame bottom surface after adjusting height on circular shaft class part; Under the situation that deck does not unclamp, be placed in dull and stereotyped go up (revolve and turn 90 degrees) to V-type frame left surface or right flank, vernier height gauge can mark second processing boundary vertical with first processing boundary after adjusting height.

When the utility model will carry out the detection of the depth of parallelism or symmetry to circular shaft class part, in the manufacturing process of axial workpiece, this axial workpiece was clamped between V-type frame and the deck all the time, only need be clamped in the V-type frame in the bench vice jaw and make.In testing process, this axial workpiece also is clamped between V-type frame and the deck all the time, only needs to be placed on the left surface of V-type frame or right flank on the flat board, just can detect the symmetry and parallel degrees of data of its measured piece with dial gauge.

The utility model have a mind to effect: axial workpiece line, detect in the process of data and between V-type frame and the deck to beginning to whole clamping together; The positioning reference of workpiece to the beginning is to not changing eventually; Thereby accomplish unifying datum; Cause part processing precision high, and, easy to detect, rapid; The range of application of this built-up jig is also wider; And this built-up jig manufacture difficulty is little, and low processing cost, maintenance are simply.

The specific embodiment

With reference to Fig. 6, Fig. 7; Be used for the built-up jig that the circular shaft class is located line fast and detected; Comprise a V-type frame 1, the bottom surface 11 of said V-type frame 1 and left surface 12, right flank 13 are vertical respectively, have on the upper surface 14 of said V-type frame 1 one be symmetrical in center line V-type groove 15; One broken line type deck 2 is installed on the upper surface 14 of said V-type frame 1, and said deck 2 forms quadrangle in V-type groove 15.

Said deck 2 is connected on the upper surface 14 of said V-type frame 1 through sunk screw 3.

Each flatness of the bottom surface 11 of the V-type frame 1 of the utility model, left surface 12, right flank 13 is at 0.02mm; The perpendicularity of bottom surface 11 and left surface 12, right flank 13 is at 0.01mm.

When the utility model will mark orthogonal processing boundary to circular shaft class part; Be clamped in circular shaft class part 4 between V-type frame 1 and the deck 2; The bottom surface 11 of V-type frame 1 put with dull and stereotyped 5 on; Vernier height gauge 6 can mark first processing boundary 41 that is parallel to V-type frame 1 bottom surface 11 after adjusting height on circular shaft class part 4, see Fig. 8; Under the situation that deck 2 does not unclamp, be placed in V-type frame 1 left surface 12 or right flank 13 on dull and stereotyped 5 (revolve and turn 90 degrees), vernier height gauge 6 is adjusted and can be marked second processing boundary 42 vertical with first processing boundary 41 behind the height, sees Fig. 9.

When the utility model will carry out the detection of the depth of parallelism or symmetry to circular shaft class part, in the manufacturing process of axial workpiece 7, this axial workpiece 7 was clamped between V-type frame 1 and the deck 2 all the time, only need be clamped in V-type frame 1 in the bench vice jaw and make.In testing process; This axial workpiece 7 also is clamped between V-type frame 1 and the deck 2 all the time; Only need to be placed on the left surface 12 of V-type frame 1 or right flank 13 on dull and stereotyped 5, just can use dial gauge 8 to detect the symmetry and parallel degrees of data of its measured piece, see Figure 10, Figure 11.

The described content of this specification embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
