Abstract

The utility model discloses a verticality inspection tester for piston pin holes, wherein a shaft seat is fixedly installed on both sides of a bottom plate; a V-shaped block is movably connected with a shaft sleeve on the shaft seat through fixing rotating shafts positioned on the both sides; a right-angled support saddle is fixedly connected with the bottom plate positioned on the left side of the V-shaped block; a detection core rod penetrates through a hole formed on the V-shaped block and is fixed on the right-angled support saddle; a meter rack is installed at the upper end of the right-angled support saddle; a meter head of a dial indicator is fixed on the meter rack and corresponds to a measuring seat fixed at the top end of the V-shaped block; and two elastic reset pins for the V-shaped block are also installed at the upper part of the right-angled support saddle. The verticality inspection tester solves the problem in the prior art that the detection error is big, has the characteristics of facilitating verticality detections of various piston pin holes and eliminating the detection error, and improves the work efficiency.

Description

Piston pin hole verticality somascope

One, technical field

The utility model relates to a kind of device that internal combustion engine pin-and-hole verticality detects that detects.

Two, background technology

Performance when piston pin hole directly influences pistons work to the verticality of skirt axis.Piston manufacturer adopts hand-held piston pin hole verticality somascope mostly at present, its principle adopts plug to insert piston pin hole one side, utilize cylindrical one end location, measure this side other end reading of pin-and-hole with dial gauge or clock gauge, insert the piston pin hole opposite side with plug again, measure the opposite side reading.Pin-and-hole both sides, both sides difference is this piston verticality numerical value.But concave surface is mostly adopted in the internal combustion engine skirt section at present, causes hand-held piston pin hole verticality somascope to detect.Simultaneously, piston pin hole directly influences testing result with respect to the position degree in skirt section, makes detected value big with respect to the error of true value.

Three, summary of the invention

Technical problem to be solved in the utility model provides a kind of can not only conveniently the detection, and has eliminated the piston pin hole verticality somascope of error in the testing process.

For solving the problems of the technologies described above, the technical scheme that the utility model piston pin hole verticality somascope adopts is: it comprises base plate and detects plug, the both sides fixed installation axle bed of described base plate, the axle sleeve on translateral fixed rotating shaft of vee-block and the axle bed flexibly connects; Fixedly connected right angle bearing on the base plate in described vee-block left side, described detection plug passes the hole of vee-block and is fixed on the right angle bearing, and dial framework is installed in bearing upper end in right angle, and the clock gauge gauge outfit that is fixed on the dial framework is corresponding with the measuring seat that is fixed on the vee-block top; Two vee-block elastic reset pins also are installed the position on the upper side at the right angle bearing.

Because technique scheme is selected suitable detection plug according to the piston pin hole diameter, will detect plug and be fixed on the right angle seat, installation dial framework in right angle seat upper end in order to fixing clock gauge, utilizes the elastic reset pin that vee-block is resetted.Rotation axis cooperates with axle sleeve, and rotation axis can not only be rotated in the uranium cover, can move axially simultaneously, to eliminate piston pin hole to the influence of position, skirt section degree to testing result.Therefore, the utility model can not only detect various piston pin hole verticality easily, and adopts automatic positioning piston pin-and-hole, has eliminated the error in the testing process, has improved work efficiency.

Four, description of drawings

Fig. 1 is the front view of the utility model piston pin hole verticality somascope;

Fig. 2 is the vertical view of embodiment shown in Figure 1.

Five, embodiment

By Fig. 1, Fig. 2 as seen, the inspection of the utility model piston pin hole verticality comprises base plate 1, the both sides fixed installation axle bed 2 of base plate 1, and the axle sleeve 5 on vee-block 3 translateral fixed rotating shafts 4 and the axle bed 2 flexibly connects; Fixedly connected right angle bearing 6 on the base plate in vee-block 3 left sides, detection plug 7 passes the hole of vee-block 3 and is fixed on the right angle bearing 6, dial framework 8 is installed in bearing 6 upper ends in right angle, and clock gauge 9 gauge outfits that are fixed on the dial framework 8 are corresponding with the measuring seat 10 that is fixed on vee-block 3 tops; Two vee-block elastic reset pins 11 also are installed the position on the upper side at right angle bearing 6.

Principle of work of the present utility model is according to the piston pin hole diameter, select suitable detection plug 7, be assembled on the somascope, then piston 12 pin-and-holes are inserted gently and detect plug 7, after pin-and-hole all inserts detection plug 7, piston 12 is pressed to vee-block 3, and at this moment vee-block 3 moves horizontally in the thrust lower edge rotating shaft 4 of piston 12, up to the cylindrical of two inclined-plane contact pistons 12 of vee-block 3.Continuation is pressed to vee-block 3 with piston 12, and vee-block 3 will be that axis rotates with two rotating shafts, 4 centers, hold out against vee-block 3 up to piston 12, when vee-block 3 rotates, is being with measuring seat 10 to press to clock gauge 9 gauge outfits, reads reading on clock gauge 9.Take off piston 12, the opposite side pin-and-hole is pressed into detects plug 7, repeat above work, read reading, the difference of two readings is its verticality.
