A volute flattening device of a washing machine comprises a workbench and is characterized in that a volute placing groove is formed in the workbench surface, the shape of the volute placing groove is consistent with that of a volute, a flattening mechanism is arranged above the volute placing groove and comprises a pressing plate, the bottom end of the pressing plate corresponds to the volute placing groove, the pressing plate is connected with a driving device, the bottom end of the pressing plate is a plane, the shape of the pressing plate is consistent with that of a convex edge in the volute, and the diameter of the pressing plate is larger than that of the convex edge in the volute; the volute casing placing groove comprises a placing groove I and a placing groove II, a through hole I corresponding to the convex part at the bottom end of the volute casing is arranged in the placing groove II, the end face of the bottom end of the placing groove I is an arc-shaped face, and the concave length of the arc-shaped face is 10mm-12 mm.

The spiral casing flattening device is further characterized in that the spiral casing placing grooves comprise at least two, and the number of the flattening mechanisms is consistent with that of the spiral casing placing grooves;

the flattening mechanism is fixed on the workbench through a support;

the bracket is n-type or m-type;

the driving device is an air cylinder, the air cylinder is arranged at the top end of the support, a through hole is formed in the top end of the support, and an air cylinder piston rod penetrates through the through hole and is fixedly connected with the top end of the pressing plate.

Adopt the above structure of the utility model can reach following beneficial effect: the volute is placed in the volute placing groove, the driving device drives the pressing plate to move downwards, so that automatic flattening operation of the volute is achieved, manual pressing is not needed, the automation degree is high, time and labor are saved, the machining efficiency can be greatly improved, the pressing force of the pressing plate is controlled through the driving device, the situation that the pressure is too large or too small is avoided, the problem that the volute is not flattened or damaged due to too large pressure due to too small pressure is effectively avoided, and the quality of a product is ensured; the bottom terminal surface of spiral case standing groove sets up to the arcwall face, and when pressing it through drive arrangement, the bottom terminal surface of spiral case hugs closely in the arcwall face, and the operation of flattening is accomplished, and after the natural cooling, the bottom terminal surface shrinkage of spiral case is smooth plane to the problem of spiral case bottom surface protruding deformation after the natural cooling has been avoided appears, has ensured product quality.

Detailed Description

Referring to fig. 1 to 4, a washing machine volute flattening device comprises a workbench 1, a volute placing groove 2 is arranged on a table top of the workbench 1, the shape of the volute placing groove 2 is consistent with that of a volute 3, a flattening mechanism 4 is arranged above the volute placing groove 2, the flattening mechanism 4 comprises a pressing plate 41, the bottom end of the pressing plate 41 corresponds to the volute placing groove 2, the pressing plate 41 is connected with a driving device 5, the driving device is an air cylinder, the bottom end of the pressing plate 41 is a plane, the shape of the pressing plate 41 is consistent with that of a raised edge 31 in the volute, and the diameter of the pressing plate 41 is larger than that of the raised edge 31 in the; the volute casing placing groove 2 comprises a placing groove I21 and a placing groove II 22, a through hole I23 corresponding to the convex piece 32 at the bottom end of the volute casing is arranged in the placing groove II 22, the end face of the bottom end of the placing groove I21 is an arc-shaped face 24, the arc-shaped face is concave downwards from the periphery of the placing groove I to the center, the concave length of the arc-shaped face is 10mm-12mm, in the figure 3, a is a plane, and l is the concave length, namely the distance between the plane a and the perpendicular line of the central point of the placing groove I21; in the embodiment, the number of the volute casing placing grooves 2 is four, and the number of the flattening mechanisms 4 is consistent with that of the volute casing placing grooves 2; flattening mechanism 4 is fixed in on workstation 1 through support 6, and support 6 is the m type, and cylinder 5 arranges in support 6 top, and support 6 top is provided with the through-hole, and the cylinder piston rod passes the top rigid coupling of through-hole and clamp plate 41.

When the flattening operation is carried out, the volute 3 is in an uncooled state after being processed and molded, the uncooled volute 3 is placed in the volute placing groove 2, the convex piece 32 at the bottom end of the volute 3 is correspondingly placed in the through hole I23, therefore, when the volute 3 is placed in the volute placing groove 2 for flattening operation, the position of the volute 3 is stable and displacement can not occur, thereby further ensuring the flatness of the bottom surface of the volute 3 during flattening, when flattening, the pressing plate 41 presses corresponding to the end surface of the top end of the inner convex edge 31 of the volute, meanwhile, the end surface of the bottom end of the volute 3 is concave downwards and is clung to the arc-shaped surface of the bottom end of the first placing groove 21, in the natural cooling process, because the convex edge 31 in the volute casing does not jump under the pressure of the pressure plate 31, meanwhile, the end face of the bottom end of the volute 3 is changed into a flat surface through cold shrinkage, and after cooling, the piston rod of the air cylinder 5 retracts to drive the pressing plate 41 to retract, so that the flattening operation of the volute 3 is realized.
