Detailed description of the invention

For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

The utility model is a kind of motor cover vehicle clamper, and as shown in Figure 1, it is made up of clamping device and positioner two parts, and with motor cover (i.e. workpiece 12) blank hole location, arc surface and both ends of the surface compress processes, as shown in Figure 5-Figure 8.

Clamping device comprises self-centering four paws body 1 and four speical laws (i.e. two the first speical law 2, second speical laws 3, the 3rd speical laws 17) and the locating piece 4 be arranged on above the second speical law 3 and the 3rd speical law 17 and forms.Positioner comprises the first location structure and the second location structure, first location structure comprises handle 5, straight pin 6 (2), stop collar 7, pull bar 8, first lining 9, be arranged on the first apotting spindle 10 on the second speical law 3 and the first spring 11, second location structure comprises the second apotting spindle 13, second spring 14, second lining 15, back-up ring 16 and the lock-screw etc. that are arranged on the 3rd speical law 17.

Self-centering four paws body 1 comprises a basin body and four small bevel gears, four small bevel gears and the engagement of basin silk, there is flat thread structure at the back side of basin silk, according to structural design four special four paws of workpiece 12 (namely four speical laws wherein two the first speical laws 2 are the size design according to the motor cover face of cylinder, the second speical law 3, the 3rd speical law 17 design according to the size of the projection of motor cover.) decile is arranged on flat thread, namely the first speical law 2, second speical law 3, the 3rd speical law 17 decile is uniform is arranged on self-centering four paws body 1.Wherein the first speical law 2 has identical two pieces, the symmetrical both sides being arranged on self-centering four paws main body 1 respectively, when the first speical law 2 designs, the size R of its clamping arc surface designs according to the size of motor cover face of cylinder diameter D, the size of R is more than or equal to the half of D, as shown in Figure 5.Second speical law 3 has installed locating piece 4 and the first apotting spindle 10 above, 3rd speical law 17 has installed locating piece 4 and the second apotting spindle 13 above, the first location structure that wherein the second speical law 3 is installed above is movable location structure, first location structure comprises the first apotting spindle 10, first apotting spindle 10 end face installs the first spring 11, the other end and the first lining 9 coordinate, the first spring 11 other end fixed by first lining 9, the outside of the first apotting spindle 10 is connected with the second speical law 3 by the first lining 9, one end of first apotting spindle 10 is connected with pull bar 8, pull bar 8 is connected with handle 5 through the stop collar 7 be fixed on the second speical law 3, be connected by straight pin 6 between stop collar 7 with handle 5, in cargo handling process, handle 5 makes pull bar 8 be in stop collar 7 two position activities, concrete installation site is as Fig. 3, shown in Fig. 4, by being threaded between pull bar 8 and the first apotting spindle 10, in order to prevent after frequent use there is the phenomenon loosened in both, affect motor cover positioning precision, thread locking adhesive is smeared at the first apotting spindle 10 and pull bar 8 threaded connection place.For ease of the handling of workpiece, the second location structure that the 3rd speical law 17 is installed is designed to fixed location structure above, makes motor cover be in two stations respectively in handling and process.The outside that second location structure comprises the second apotting spindle 13, second apotting spindle 13 is connected with the 3rd speical law 17 by the second lining 15, and the 3rd speical law 17 is provided with back-up ring 16, and back-up ring 16 is fixedly connected with the second apotting spindle 13 by lock-screw.The end face of the first apotting spindle 10 and the end face of the second apotting spindle 13 are separately installed with the first spring 11 and the second spring 14, according to blank dimension size, regulate position location voluntarily by spring force.Wherein, first spring 11 and the second spring 14 are the position locations regulating the first apotting spindle 10 and the second apotting spindle 13 respectively, the structure of this first apotting spindle 10 and the second apotting spindle 13 is tapered configuration, carry out self-control under the action of the spring, the problems such as the molten error of motor cover blank endoporus is large can be eliminated.In addition, on the second speical law 3 and the 3rd speical law 17, locating piece 4 has been installed respectively, to reach the object of clamping work pieces 12.

The utility model utilizes the feature of self-centering four paws, because the pitch of the planar rectangular screw thread on parcel is equal, so four speical law move distances are equal, when rotating self-centering four paws body 1, reaches the object of location, clamping work pieces 12.

Before workpiece 12 is processed, in order to make the first speical law 2 laminating motor cover arc surface preferably, first the arc surface above the first speical law 2 is carried out turnery processing according to the actual size of blank, adjustment arc surface is equal to workpiece 12 clamping area distance L with locating piece face, as shown in Figure 6 and Figure 7.

Before workpiece 12 clamping, handle 5 is moved to the position of the first station 18, as shown in Figure 8, after workpiece 12 clamping, move to the position of the second station 19 again, the first apotting spindle 10 is made to reach the object of location under spring force, the small bevel gear on self-centering four paws body 1 is pulled with spanner, parcel is rotated, the flat thread at its back side just makes four speical laws (two the first speical laws 2, second speical law 3 and the 3rd speical law 17) simultaneously close to center, because the pitch of the planar rectangular screw thread on parcel is equal, so under the rotation of parcel, four paws move distance is equal, thus reach location, the object of clamping work pieces 12.Same when workpiece 12 is dismantled, rotate parcel, make four speical laws away from workpiece 12, then move handle to first station 18 from the second station 19.
