Description

Thin-wall part cylinder body positioning clamping device

Technical field

The utility model relates to a kind of thin-wall part cylinder body positioning clamping device, belongs to technical field of tooling clamps, and it is yielding to be used for the thin-walled parts clamping, the thin-wall part cylinder body location that difficulty of processing is big.

Background technology

The thin-walled parts clamping very easily is out of shape, and difficulty of processing is big, and therefore, thin-walled parts is difficult to guarantee crudy, comprises the position degree in flatness, the depth of parallelism, axiality, roughness, important hole etc.The domestic main at present artificial clamping that adopts is carried out single and mini-batch production processing.As process lower cylinder body (ZD30 cylinder body) in enormous quantities with transfer matic, there are many technical barriers in clamping workpiece, and home equipment seldom has successful examples.

Summary of the invention

The purpose of this utility model mainly is in order to solve that the big facing cut of thin-walled parts is cut the problem of clamping, machining deformation and a kind of thin-wall part cylinder body positioning clamping device of designing.

The technical solution of the utility model: thin-wall part cylinder body positioning clamping device of the present utility model comprises base, clamp mechanism, clamp mechanism comprises clamp jaw and the driving mechanism thereof that is installed in base and bilateral symmetry layout, driving mechanism adopts cylinder device, the root of the output piston bar of hydraulic cylinder and the pawl head of clamp jaw is hinged by first jointed shaft, the middle part of pawl head is hinged between the end of a pair of connecting plate by second jointed shaft, the other end of a pair of connecting plate is installed on the bearing by the 3rd jointed shaft, and bearing is installed on the base.

Described thin-wall part cylinder body positioning clamping device, the clamp jaw of arranging in the base bilateral symmetry has three pairs six.

Described thin-wall part cylinder body positioning clamping device is installed supplemental support on the interior wing base of clamp jaw, supplemental support has four, has one to be positioned at base one middle side part, and other is positioned at four jiaos of base.

Described thin-wall part cylinder body positioning clamping device is installed block and buting iron on the control stick of hydraulic cylinder, cooperate block and buting iron that first limit switch and second limit switch are installed, and hydraulic cylinder travel is played position-limiting action.

Advantage of the present utility model:, realized processing lower cylinder body in enormous quantities automatically by anchor clamps and location are clamped auxilliary selection.After adopting this technology, the crucial working position of lower cylinder body satisfies the product design requirement as the position degree in the flatness of top and bottom, roughness, important hole etc.Working (machining) efficiency improves, and workman's operation intensity descends, and workpiece processing uniformity is well guaranteed.

Description of drawings

Fig. 1 is the general structure schematic diagram of overlooking of the present utility model.

Fig. 2 is a clamp mechanism plan structure schematic diagram.

Fig. 3 is the F-F view (clamp mechanism is in clamped condition) of Fig. 1.

Fig. 4 is the F-F view (clamp mechanism is in open configuration) of Fig. 1.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

As Fig. 1: thin-wall part cylinder body positioning clamping device of the present utility model comprises base 1, and its clamp mechanism comprises and be installed in clamp jaw 3 and the driving mechanism thereof that base 1 bilateral symmetry is arranged that the clamp jaw of arranging in base 1 bilateral symmetry has three pairs six.

Supplemental support 2 is installed on the interior wing base of clamp jaw, and supplemental support 2 has four, has one to be positioned at base 1 one middle side parts.

As Fig. 2, Fig. 3, Fig. 4: driving mechanism adopts cylinder device, the root of the pawl head 3a of the output piston bar 4a of hydraulic cylinder 4c and clamp jaw is hinged by the first jointed shaft 3b, the middle part of pawl head 3a is hinged between the end of a pair of connecting plate 3c by the second jointed shaft 3d, the other end of a pair of connecting plate 3c is installed on the bearing 3f by the 3rd jointed shaft 3e, and bearing 3f is installed on the base 1.4b is a front end flange.The 5th, workpiece.

Workpiece 5 is located earlier by 4 supplemental support 2 of bottom surface after carrying and putting in place, and workpiece is subjected to uniform cutting force in the processing in order to make, and arranges that in base 1 bilateral symmetry three pairs of six clamp jaws clamp workpiece 5 in the workpiece two sides.Add man-hour, hydraulic cylinder 4c piston rod 4a promotes forward, pawl head 3a is moved up, when pawl head 3a moved up, owing to pining down of connecting plate 3c, pawl head 3a self inwardly rotated around the first jointed shaft 3b on the one hand, on the other hand, drive connecting plate 3c and rotate around the 3rd jointed shaft 3e, make slowly contact workpiece 5 of pawl head 3a, pawl head 3a clamps workpiece blank from the side.When opening, action is opposite.

The stroke of 8,12 couples of hydraulic cylinder 4c of limit switch plays position-limiting action, guarantees whether clamping work pieces is appropriate.When hydraulic cylinder 4c moved upward, the control stick 6 that is connected with piston 7 upwards promoted, and drove block 10 and moved, and when block 10 touched first limit switch 8, the expression jaw was finished the clamping of side surface of workpiece.Unclamp step in contrast, when buting iron 9 touched second limit switch 12, the expression jaw was finished unclamping of side surface of workpiece.The 11st, mounting bracket.

Because this processing belongs in the machining difficult thin-walled processing, by workpiece blank casting benchmark being positioned and bottom surface and side and middle non-machining area being clamped.Guarantee that the workpiece work in-process is subjected to vibration influence little, realizes automatic batch production.
