The multiple varieties refer to different varieties of axle housing parts formed by V-shaped positioning axle housing parts due to the fact that the sizes of positioning and limiting parts are changed; the V-shaped positioning means that the parts adopt a positioning mode of V-shaped at two ends.

Background

The axle housing part of the front drive steering axle of the tractor is usually formed by adopting a casting technology and belongs to a material with a longer unidirectional (axial) size. In the forming process, a large amount of casting sand, powder and other impurities are adhered to the inner wall and the outer wall of an axle housing part, particularly the inner cavity wall, and some impurities still remain on the inner cavity wall although the impurities are forcibly cleaned by shot blasting and the like; in addition, in the machining process, impurities such as scrap iron, powder and the like are easily brought into the inner cavity of the axle housing part; furthermore, during the storage and transportation process, some external fine particles such as production dust are liable to enter the inner cavity of the axle housing component.

Before assembling parts of a front drive steering axle of a tractor, the cleaning treatment of the inner surface and the outer surface of an axle housing part is generally required. If the cleaning is not in place, especially the cleaning quality of the inner cavity of the axle housing is low, the impurities such as molding sand, scrap iron, powder dust and the like in the inner cavity of the axle housing cannot be cleaned, the residual impurities can easily invade into a kinematic pair in the operation process after assembly, and the operation parts are worn, namely the working quality and the service life of important motion parts such as a main speed reducing assembly, a tail end speed reducing assembly, a steering system assembly and the like arranged in the inner cavity of the axle housing part are reduced, and in serious cases, the tractor can be scrapped too early or safety quality accidents are caused, especially for the manufacturing industry of agricultural equipment such as high-end tractors and the like which are formed in recent years.

This dolly includes: the device comprises a vehicle body component 2, a left end V-shaped positioning component 3, a plane limiting component 4, a right end V-shaped positioning component 5, a flat wheel component 6, a V-wheel component 7 and a bearing component 8 with a waterproof seat; wherein, left end V type locating component 3, plane spacing subassembly 4, right-hand member V type locating component 5 and automobile body subassembly 2 all adopt welded mode to connect firmly. This dolly not only can bear axle housing part (V type axle housing 1) and can satisfy the step-by-step transport demand that the dolly steady with non-lifts up gently on above-mentioned "electronic two shift fork step-by-step conveyor", but also the axle housing part (V type axle housing 1) inside and outside surface cleaning on the dolly of being convenient for, insert the suitability demand that the axle housing inner chamber was washd and the operation gyro wheel was washd and is prevented corroding including having solved accurate positioning and spacing problem of placing and satisfying above-mentioned "electric probe belt cleaning device".

Further explanation is as follows: the dolly among the above-mentioned patent technique, though to axle housing part (V type axle housing 1) accurate positioning lay with spacing, interior external surface washing, marching type transport, the gyro wheel aspect of preventing corroding, have positive beneficial effect, but its this dolly still has certain limitation on its practical range aspect of using.

Description of the invention: after the trolley is manufactured, the trolley is only suitable for cleaning a single variety of V-shaped positioning axle housing parts and cannot be used for cleaning different types of V-shaped positioning axle housing parts formed by the changes of positioning and limiting sizes. That is, when one or more changes occur in relation to the four dimensions "distance L1 between the outer circumferential side end faces of the two positioning circles, phi d, widest distance L2 of the mounting hole, and distance H between the axle housing center line and pipa" of the axle housing, the axle housing parts cannot be reliably cleaned on the manufactured truck.

Description is continued: in view of the situation, if a certain kind of axle housing needs to be changed and cleaned, the finished trolley needs to be improved, for example, when three dimensions of the distance L1 between the side end faces of the two positioning outer circles, the diameter d of the positioning outer circle and the widest distance L2 of the mounting hole change, the left-end V-shaped positioning component 3, the plane limiting component 4 and the right-end V-shaped positioning component 5 which are welded on the trolley body component 2 need to be forcibly removed and cleaned one by one, and are re-manufactured according to the changed dimensions, and particularly need to be re-welded on a required position on the trolley body component 2, so that the time is wasted, the variety is difficult to be quickly changed, the requirement for quick change in actual production is met, the vehicle body is easy to damage, and in addition, if dozens of finished trolleys of axles are arranged on a stepping conveying line, the improvement workload of variety change is larger, and the time is longer.

Further explanation is as follows: even if the improvement of the trolley is completed, the improved trolley is still only suitable for cleaning axle housing parts of one variety, if the variety is changed again or cleaning application of the variety before the change is repeated, the improvement process is repeated, and the improvement is feasible, not preferable and not necessary.

In summary, in order to satisfy the requirement of cleaning various 'V-shaped positioning' axle housing parts, the applicant has found that no known technology can be read and used for reference at present, a new way needs to be developed for expansibility research, and the problem is also a practical problem to be solved.

2-1) W1 dimensional processing considerations with "component variation

According to the clear component difference compared with W1= L1+2W2+ W3, the positions of bolt holes needed by the complementary processing of the left-end perforated bolt 21 and the right-end perforated bolt 33 on the two left-end replaceable perforated base plates 17 and the two right-end replaceable perforated base plates 29 in the spatial position layout are determined; if yes, the four replaceable hole base plates can be detached, namely, the required bolt holes are additionally machined on the existing parts according to the component difference values, and machining items after the W1 size is changed are completed; if not, the four new parts of the replaceable holed backing plate are manufactured without selecting materials again, the required bolt holes are processed according to the component difference value, and the processing items after the size of W1 is changed can be finished in the same way;

2-2) h4 size processing issues with "component variation

According to the definite component difference value compared with h4= d ÷ 2", whether the left end positioning block 22 and the right end positioning block 34 which are manufactured by re-selecting materials are feasible or not is known and determined; if yes, detaching the workpiece, and selecting materials again to manufacture a new part of the positioning block according to the condition of the component difference, so that the processing item after h4 size change can be finished; if not, the positioning block, the left-end replaceable V-shaped seat 20 and the right-end replaceable V-shaped seat 32 are detached together, and new parts of the replaceable V-shaped seat are manufactured by selecting materials again according to the condition of component difference, wherein the new parts comprise V-shaped opening inclined plane-shaped machining, and machining items after h4 size change can be finished;

2-3) W4 dimensional processing issues with "component variation

According to the clear assembly difference of W4= L2 +/-20, the positions of the cushion plate grooves required by additionally processing the two limit plates 26 are determined on the two replaceable groove cushion plates 24 according to the spatial position layout; if yes, the two 'replaceable groove backing plates' can be detached, namely the required backing plate grooves are additionally machined on the existing parts according to the 'component difference', and then machining items after the W4 size is changed can be completed; if not, two conditions are adopted, namely after the limiting plate 26 is adopted to carry out plane limiting, if the mounting screw hole 1b on the axle housing lute surface 1a is not shielded, cleaning of the axle housing lute surface is not influenced, namely although the W4 size is equal to the component difference value, the situation that the difference value is not generated can be considered as the situation, the existing part, namely the replaceable groove base plate 24, can be continuously used, dismounting and processing are not required to be carried out, and the processing item after the W4 size is changed is considered to be finished; secondly, if the cushion plate grooves are shielded and are not distributed and processed in a spatial position, the two new parts of the cushion plate with the replaceable grooves need to be manufactured by selecting materials again, the required cushion plate grooves are processed according to the component difference value, and the processing items after the W4 size is changed can be finished in the same way;

2-4) h1 size processing issues with "component variation

1) Component transformation usage involving variation of dimension L1 (corresponding to W1)

According to whether the bolt holes with changed sizes are additionally processed on the two left-end replaceable perforated base plates 17 and the two right-end replaceable perforated base plates 29, the following two conditions are divided:

1-1) if the bolt hole is subjected to the complementary processing, the left-end replaceable V-shaped positioning component 10 and the right-end replaceable V-shaped positioning component 12 which are used already need to be dismounted, and the replaceable perforated base plate without the complementary processing in the left-end replaceable V-shaped positioning component and the right-end replaceable V-shaped positioning component is replaced with the replaceable perforated base plate with the complementary processing bolt hole, wherein the left-end perforated bolt 21 and the right-end perforated bolt 33 in the replaceable perforated base plate are replaced with the positions and placed in the bolt hole subjected to the complementary processing, and then the positioning component can be replaced and used; it should be noted that, this transformation system is the first time, if the transformation is completed and the transformation is still needed to be used again for a certain variety before transformation, the two "replaceable V-shaped positioning assemblies" do not need to be dismounted, and only the two "holed bolts" need to be taken out and directly inserted in the changed positions, that is, the two "replaceable V-shaped positioning assemblies" are directly put into the same "replaceable holed backing plate" and are suitable for the bolt holes needed to be used for a certain variety before transformation;

1-2) if the bolt hole which is additionally processed is not available, namely the left-end replaceable V-shaped positioning component 10 and the right-end replaceable V-shaped positioning component 12 which are used are dismounted, the used left-end replaceable V-shaped positioning component and the right-end replaceable V-shaped positioning component 12 are replaced, the used replaceable porous cushion plate is replaced, and new parts of the left-end replaceable porous cushion plate 17 and the right-end replaceable porous cushion plate 29 which are manufactured by re-material selection are arranged in the newly processed bolt hole, and the replacement of the positioning component can be completed; it should be noted that, if it is necessary to replace the original replaceable holed cushion plate without the complementary processing bolt hole, then the two pin hole positioning assemblies are mounted on the left and right ends of the upper end surface 12a of the car body, and the two replaceable V-shaped positioning assemblies are replaced in the bolt holes required by the original product, so that the positioning assemblies can be replaced and used, that is, the two replaceable holed cushion plates without the complementary processing bolt hole can still be used;

2) Use of conversion of components involving variation of dimension Phd (corresponding to h 4)

The manufacturing of the left end positioning block 22 and the right end positioning block 34 or the left end replaceable V-shaped seat 20 and the right end replaceable V-shaped seat 32 according to whether the materials are selected again is divided into the following two conditions:

2-1) if the material is selected again to manufacture the positioning block, the used left end positioning block 22 and right end positioning block 34 need to be dismounted, and the new part of the positioning block manufactured by selecting the material again needs to be replaced, thus completing the replacement of the components;

2-2) if the material is selected again to manufacture the replaceable V-shaped seat, the left-end replaceable V-shaped positioning component 10 and the right-end replaceable V-shaped positioning component 12 need to be dismounted, the left-end replaceable V-shaped seat 20 and the right-end replaceable V-shaped seat 32 are replaced, and new parts of the replaceable V-shaped seat manufactured by selecting the material again are replaced, so that the components can be used in a replaceable way;

3) Component transformation usage involving variation of dimension L2 (corresponding to W4)

3-1) if the ' complementary processing backing plate groove exists ', two ' replaceable plane limiting assemblies 11 ' are needed to be dismounted, and the ' replaceable groove backing plate ' without the ' complementary processing backing plate groove is replaced with a ' replaceable groove backing plate ' with the ' complementary processing backing plate groove, and the replacement of the assembly can be completed by replacing the positions of the two ' limiting plates 26 ' and placing the two ' limiting plates into the complementary processing backing plate groove; it should be noted that, this transformation system is the first time, if the transformation is completed and the transformation is still needed to be changed again for use, only two limiting plates need to be taken out, and the position is directly changed and inserted, that is, the two limiting plates are directly placed on the same replaceable groove base plate and are suitable for the base plate groove needed to be used by a certain variety before transformation;

3-2) if the shim plate groove is not subjected to complementary processing, but the cleaning use requirement of the mounting screw hole 1b is not influenced after the limiting plate 26 is placed, the used replaceable plane limiting component 11 is not required to be dismounted, and the replaceable shim plate used for a certain variety before conversion can be continuously used, so that the component can be used for conversion;

3-3) if the 'no' additionally processed base plate groove is formed and the situation does not belong to the situation of the step 3-2), namely the 'replaceable groove base plate' needs to be manufactured by selecting materials again and the base plate groove with changed 'size' is newly processed, the used 'replaceable plane limiting component 11' needs to be dismounted, the two 'replaceable groove base plates 24' used in the 'replaceable groove base plate' which is manufactured by selecting materials again are replaced, and the 'replaceable groove base plate' which is manufactured by selecting materials again comprises the step of placing the two 'limiting plates 26' in the newly processed base plate groove, so that the components can be changed and used; it should be noted that, if a certain product before conversion needs to be used again, the replaceable groove cushion plate with the ' no ' additionally processed cushion plate groove removed can be replaced again, and then the ' replaceable plane limiting component 11 ' matched with the replaceable groove cushion plate can be installed in the middle of the upper end surface 13a of the vehicle body, including two ' limiting plates 26 ' are replaced again into the cushion plate groove needed to be used by the certain product before conversion, so that the positioning component can be used again, that is, the two ' replaceable groove cushion plates ' without ' additionally processed bolt holes used by the certain product before conversion can still be used continuously;

4) Component transformation usage involving variation of dimension H (corresponding to H1)

The replaceable plane limiting component 11 is used before the size is dismounted, the number of the adjusting gaskets 25 for limiting surfaces, which need to be increased or decreased at the position where each fastener 27 for the groove cushion plate is completed, is determined according to the size h1 after the size is changed, and then the newly-replaced replaceable plane limiting component 11 is mounted in the middle of the upper end surface 13a of the vehicle body, so that the positioning component can be used in a replacement mode.
