Description
Technical field
The utility model relates to a kind of overturn clamping device for engine cylinder-body machining production line, especially a kind of overturn clamping device for heavy-duty engine cylinder body.
Background technology
In the machining production process of heavy-duty engine cylinder body, in the man-hour that adds of carrying out cylinder deck hole, the upset that needs cylinder body to carry out workpiece attitude according to the orientation of platen changes.Prior art adopts mouse cage type structure upset more, before and after tipper, conveyer is set, and engine delivers into tipper by conveyer, after having overturn, transports out and lifts, and its equipment cost is high, inconvenient operation.Also there is employing to stand up cucurbit and overturn under lifting state, for heavy-duty engine, upset difficulty, poor stability.In the production practices of engine cylinder-body, need a kind of overturn clamping device, can realize horizontal level and clamp, while turning to rolling condition, can automatically open engine, meet safty hoisting requirement.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of overturn clamping device for engine cylinder-body processing, in the process of upset, can automatically complete the clamping of cylinder body horizontal level, automatically open while turning to rolling condition, is convenient to safty hoisting operation.
The utility model adopts following technical scheme: comprise support, rollover stand and four clamp arms, support is provided with gear driven mechanism and two pairs of support rollers, described rollover stand is provided with a pair of arc-shaped rail, described two pairs of support rollers and a pair of arc-shaped guide rail match, described gear driven mechanism can drive rollover stand to do swing upset, the hinged end of described four clamp arms is articulated with respectively four bights of rollover stand by the first pin joint, described clamp arm is provided with the attitude switching mechanism that can drive clamp arm to clamp or open, described attitude switching mechanism comprises pair of cams geosynclinal block, four lifting arms and four cover for seat, described pair of cams geosynclinal block is positioned at arc-shaped guide rail both sides and is fixed on support, the lower end of described lifting arm is provided with the lifting roller that the notch with cam geosynclinal block matches, the upper end of described lifting arm is provided with extension, described extension is hinged by the second pin joint of articulated slab and clamp arm hinged end, four cover for seat are individually fixed in four bights of rollover stand, lifting arm is installed in cover for seat, when rollover stand overturns on support, lifting roller rolls in the notch of cam geosynclinal block, lifting roller drives lifting arm to slide up and down in cover for seat.
Its operation principle is: gear driven mechanism can drive rollover stand on support, to do swing upset, its flip angle at-60 degree to (horizontal level is 0 degree) within the scope of+60 degree.The initialization state of the utility model device is that rollover stand is turned into rolling condition (corner-60 degree or+60 degree) to the left or to the right.Turn in the process of rolling condition, attitude switching mechanism drives two clamp arms of upside progressively to open, and two clamp arms of opposite side keep clamped condition, and now engine cylinder-body can be by crane gear lifting turnover rollover stand.
The principle of attitude switching mechanism is realized the Automatic-clamping of engine cylinder-body and opened by cam mechanism and leverage.Rollover stand is in switching process, lifting arm is by the guiding of lifting roller (lifting roller rolls in the notch of cam geosynclinal block), automatically realize lifting, lifting arm drives extension lifting, extension is again by the leverage between articulated slab and clamp arm, that realizes clamp arm opens, clamps action conversion, corner-60 degree or+during the position of 60 degree, two clamp arms of upside open, two clamp arms of opposite side keep clamped position, engine cylinder-body can free in and out rollover stand, lifts operation.When turning to horizontal level (corner is 0 degree), by the guiding of lifting roller, lifting arm drives extension, articulated slab, and by leverage, four clamp arms all remain clamped condition.
A kind of improvement is that two extensions being located at rollover stand left side are connected by the first link arm, and two extensions being located at rollover stand right side are connected by the second link arm.This draw bail not only intensity and rigidity better, bearing capacity is stronger, also can realize two clamp arm synchronous operations of homonymy.
Adopt the utility model, the operation requirements that engine cylinder-body end face hole manufacturing procedure need be overturn to workpiece attitude can be met, in switching process, the clamping of engine cylinder-body horizontal level can be automatically completed, when upset puts in place, can automatically open, be convenient to security implementation lifting operation.

The specific embodiment
As shown in Figures 1 to 4, a kind of embodiment of the utility model comprises support 1, rollover stand 2 and four clamp arms 3, support 1 is provided with gear driven mechanism 4 and two pairs of support rollers 5, described rollover stand 2 is provided with a pair of arc-shaped rail 6, described two pairs of support rollers 5 match with a pair of arc-shaped guide rail 6, described gear driven mechanism 4 can drive rollover stand 2 to do swing upset, the hinged end 7 of described four clamp arms 3 is articulated with respectively four bights of rollover stand 2 by the first pin joint 8, described clamp arm 3 is provided with the attitude switching mechanism 9 that can drive clamp arm 3 to clamp or open, described attitude switching mechanism 9 comprises pair of cams geosynclinal block 10, four lifting arms 11 and four cover for seat 12, described pair of cams geosynclinal block 10 is positioned at arc-shaped guide rail 6 both sides and is fixed on support 1, the lower end of described lifting arm 11 is provided with the lifting roller 13 that the notch with cam geosynclinal block 10 matches, the upper end of described lifting arm 11 is provided with extension 14, described extension 14 is hinged by articulated slab 15 and the second pin joint 16 of clamp arm 3 hinged ends 7, four cover for seat 12 are individually fixed in four bights of rollover stand 2, lifting arm 11 is installed in cover for seat 12, when rollover stand 2 overturns on support 1, lifting roller 13 rolls in the notch of cam geosynclinal block 10, lifting roller 13 drives lifting arm 11 to slide up and down in cover for seat 12.
Its operation principle is: gear driven mechanism 4 can drive rollover stand 2 on support 1, to do swing upset, its flip angle at-60 degree to (horizontal level is 0 degree) within the scope of+60 degree.The initialization state of the utility model device is that rollover stand 2 is turned into rolling condition (corner-60 degree or+60 degree) to the left or to the right.Turn in the process of rolling condition, attitude switching mechanism 9 drives two clamp arms 3 of upside to open, and two clamp arms 3 of opposite side keep clamped condition, and now engine cylinder-body 17 can enter rollover stand 2 by crane gear lifting.As shown in Figure 3, hang in after rollover stand 2 waist of two clamp arm 3 supporting engines cylinder bodies 17 in left side.Turn to clockwise in the process of level, the lifting roller 13 of clamp arm 3 is along the notch operation of cam geosynclinal block 10, left side lifting roller 13 is limited in notch, clamp arm 3 is contacted with engine cylinder-body 17 all the time, the lifting roller 13 on right side is entered the notch of cam geosynclinal block 10 by the free state declining, in cam geosynclinal block 10 track diameters change procedure from large to small, lifting arm 3 rises with respect to cover for seat 12, promoting extension 14 rises, extension 14 promotes the second pin joint 16 by the leverage between articulated slab 15 and clamp arm 3 again, thereby realize the clamping of clamp arm 3.By horizontal-clamping state turnover to corner-60 degree or+the one-sided states that open of 60 degree, course of action is contrary, operation logic is consistent.
