Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engine cylinder bore detection, in particular to an engine cylinder bore net texture detection tool. BACKGROUND

[0002] The engine is the heart of the automobile and the core component of the automobile. The running effect of the engine directly affects the power of the whole vehicle. The traditional fuel vehicle engine adopts a crank connecting rod mechanism, that is, the piston makes reciprocating motion inside the cylinder bore to convert chemical energy into mechanical energy. The precision of the inner wall of the cylinder bore of the engine cylinder body is particularly important. The roughness inside the engine cylinder bore and the related size parameters should be within a certain range, neither too large nor too small. If the surface roughness of the cylinder bore is too rough, it will cause friction to the aluminum alloy piston. If the surface roughness of the cylinder bore is too precise, the inner wall of the cylinder bore cannot adhere to the oil droplets, and cannot form an oil film, which cannot play a lubricating role on the piston, causing the piston to generate heat by friction, the temperature rises, and the piston is locked. Therefore, the cylinder bore net texture and roughness need to be measured in view of the above phenomenon.

[0003] The cylinder bore of the cylinder body needs to be honed after boring. Fine grooves are formed on the surface of the cylinder bore through honing. These grooves are regularly arranged in a cross pattern to form a net texture. The qualified cylinder bore net texture can effectively increase the adhesion of lubricating oil, reduce the wear of the moving parts, improve the heat dissipation efficiency, and thus increase the performance and service life of the engine. The current traditional measuring device can only be applied to in-line cylinder bodies, and it is difficult to measure V-type engines. SUMMARY

[0024] The present application will be further described in detail below through specific embodiments and in conjunction with the drawings.

[0025] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the present embodiment provides an engine cylinder 500 hole mesh detection tool, which comprises a supporting base 100, a turnover base 200, an elastic supporting piece 300 and a rotating base 400 for carrying the engine cylinder 500; the bottom of the turnover base 200 is pivoted on the supporting base 100, the rotating shaft of the turnover base 200 is parallel to the supporting base 100, the rotating base 400 is rotatably installed on the turnover base 200, and the rotating shaft of the rotating base 400 is perpendicular to the supporting base 100; a plurality of positioning holes 110 are formed in the supporting base 100, the elastic supporting piece 300 is detachably inserted into the positioning hole 110, and the top of the elastic supporting piece 300 can abut against the outer side wall of the engine cylinder 500.

[0026] Specifically, in operation, the worker hoists the V-type engine cylinder 500 onto the rotating base 400, then inserts the elastic supporting piece 300 into the positioning hole 110 of the supporting base 100, then the worker pushes the turnover base 200 to rotate relative to the supporting base 100, at this time the V-type engine cylinder 500 on the rotating base 400 is synchronized with the turnover base 200 to turn over, the outer side wall of the V-type engine cylinder 500 can abut against the elastic supporting piece 300, at this time the elastic supporting piece 300 is adjusted to be located in different positioning holes 110, so that the cylinder hole of the V-type engine cylinder 500 is in a vertical state, that is, the surface of the cylinder hole of the cylinder body is horizontally placed, and measurement is realized. When detecting the cylinder hole of the other row of the V-type engine, the worker pushes the turnover base to reset, then rotates the rotating base 400, so that the rotating base 400 rotates 180 degrees relative to the turnover base 200, then turns over the turnover base 200 again, so that the outer side wall of the V-type engine cylinder 500 abuts against the elastic supporting piece 300, at this time the surface of the other row of cylinder hole can be horizontally placed to realize measurement. Through such arrangement, the measurement of the mesh in the cylinder hole on the left and right sides of the V-type cylinder body is realized.

[0027] It should be noted that the longitudinal section of the flip base 200 is inverted triangular in shape, and the bottom of the flip base 200 is pivotally connected to the support base 100. Thus, when the flip base 200 is flipped, the tilt angle of the top support surface of the flip base 200 can be adjusted, thereby adjusting the tilt angle of the cylinder bore surface of the V-type engine cylinder 500 located on the top support surface of the flip base 200, so that the cylinder bore surface of the V-type engine cylinder 500 is placed horizontally for subsequent measurement work.

[0028] The support base 100 is provided with a pivot seat 130, and a flipping shaft 140 is provided on the pivot seat 130. The flipping base 200 is sleeved on the flipping shaft 140 so that the flipping base 200 can be flipped relative to the support base 100.

[0029] See Figures 1-6 As shown, in an optional embodiment, the top of the flip base 200 is provided with a rotating mounting hole 210, and the bottom of the rotating base 400 is provided with a rotating platform 410, which is disposed in the rotating mounting hole 210.

[0030] Specifically, a rotating platform 410 is provided at the bottom of the rotating base 400, and a rotating mounting hole 210 is provided at the top of the flip base 200. The rotating platform 410 at the bottom of the rotating base 400 is installed in the rotating mounting hole 210 on the flip base 200. With this arrangement, the rotating base 400 can rotate relative to the flip base 200.

When the rotating base 400 is at the initial 0 degrees, the positioning groove at the bottom of the rotating base 400 can engage with the ball-head plungers 220 on the top of the flip base 200, thereby maintaining the stability of the rotating base 400 and preventing the rotating base 400 from rotating arbitrarily.

[0033] In addition, when the operator needs to rotate the rotating base 400, the operator can push one side of the rotating base 400 to disengage the positioning groove of the rotating base 400 from the ball plunger 220, so that the rotating base 400 can rotate horizontally by 180 degrees. At this time, the positioning groove at the bottom of the rotating base 400 can engage with the ball plunger 220 to reposition the position of the rotating base 400 and prevent the rotating base 400 from rotating arbitrarily.

[0034] It should be noted that there are at least three ball plungers 220, and the number of positioning grooves is greater than the number of ball plungers 220, so that the positioning grooves can engage with all ball plungers 220 when the rotating base 400 rotates 0 degrees and 180 degrees.

[0035] See Figures 1-6 As shown, in an optional embodiment, the top of the rotating base 400 is provided with a plurality of positioning pins 420 for positioning the engine cylinder 500.

[0036] Specifically, multiple positioning pins 420 are provided on the top of the rotating base 400. When the workers hoist the V-type engine cylinder 500 onto the rotating base 400, the V-type engine cylinder 500 cooperates with the multiple positioning pins 420 on the top of the rotating base 400 to ensure that the V-type engine cylinder 500 is stably placed on the rotating base 400 and to prevent the V-type engine cylinder 500 from sliding on the rotating base 400.

[0037] The locating pin 420 can be a circular locating pin 420 or a diamond-shaped locating pin 420, etc., and those skilled in the art can choose according to actual needs.

[0038] See Figures 1-6 As shown, in the optional scheme of this embodiment, multiple positioning holes 110 are arranged in groups, and the extension direction of each group of positioning holes 110 is consistent with the flipping direction of the flipping base 200; multiple groups of positioning holes 110 are arranged alternately on the support base 100.

[0039] Specifically, multiple positioning holes 110 are provided on the support base 100, and the positioning holes 110 are arranged in groups. The extension direction of each group of positioning holes 110 is consistent with the flipping direction of the flipping base 200, and the multiple groups of positioning holes 110 are arranged in an alternating manner. With this setting, the operator can adjust the distance between the elastic support 300 and the flipping base 200, and there are more distance adjustment options.

[0040] See Figures 1-6 As shown, in the optional embodiment, the elastic support 300 includes a support cylinder 310, a support spring 320, and a support cylinder 330; the support spring 320 is disposed inside the support cylinder 310, one end of the support cylinder 330 is inserted into the support cylinder 310, and the other end protrudes out of the support cylinder 310; one end of the support cylinder 330 inserted into the support cylinder 310 abuts against the support spring 320; the support cylinder 310 is inserted into the positioning hole 110.

[0041] Specifically, the elastic support 300 includes a support cylinder 310, a support spring 320, and a support cylinder 330. The support cylinder 310 is detachably inserted into the positioning hole 110, the support spring 320 is inserted into the support cylinder 310, and one end of the support cylinder 330 is inserted into the support cylinder 310. When the side wall of the V-type engine cylinder 500 abuts against the support cylinder 330, the support cylinder 330 can compress the support spring 320, thereby supporting the V-type engine cylinder 500.

[0042] See Figures 1-6 As shown, in an optional embodiment, a reset hydraulic component 120 for assisting the resetting of the flip base 200 is provided on the support base 100; one end of the reset hydraulic component 120 is pivotally connected to the support base 100, and the other end is pivotally connected to the side wall of the flip base 200. The reset hydraulic component 120 and the positioning hole 110 are located on both sides of the flip base 200, respectively.

[0043] Specifically, a reset hydraulic component 120 is provided on the support base 100. When the operator rotates the flip base 200 to reset to the initial state, the reset hydraulic component 120 can assist the flip base 200 to reset to the initial state, reducing the workload of the operator.
