Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0028] See also Figure 1 The present application first provides an embodiment of an engine thrust plate structure that prevents falling and error, and the embodiment includes:
[0029] An upper thrust plate 1 and a lower thrust plate 2;
[0030] The upper thrust plate 1 is semi-arc-shaped, one end of the semi-arc is a flat edge 11, and the other end is provided with an upper anti-mistake wedge structure 12;
[0031] The lower thrust plate 2 is semi-arc-shaped, and an anti-error rectangular boss 21 is provided at one end. The anti-error rectangular boss 21 is in contact with the flat edge 11 of the upper thrust plate. A lower anti-error wedge structure 22 is provided at the other end of the lower thrust plate 2. The lower anti-error wedge structure 22 is in contact with the upper anti-error wedge structure 12.
[0032] Optionally, the ratio of the long side width of the anti-error rectangular boss 21 to the width of the lower thrust plate 2 is 2:1.
[0033] Optionally, one side of the anti-error rectangular boss 21 is flush with the inner circle of the lower thrust plate 2, and the other side extends outward.
[0034] Optionally, the extended end of the anti-error rectangular boss 21 is used to fall into a corresponding countersunk hole in the machine body.
[0035] Optionally, the upper thrust plate 1 is provided with a first oil groove 13, and the first oil grooves 13 are evenly distributed on the upper thrust plate.
[0036] Optionally, the long side width of the first oil groove 13 is equal to the width of the upper thrust plate 1 , and the first oil groove 13 is directly slotted from the upper thrust plate 1 .
[0037] Optionally, the lower thrust plate 2 is provided with second oil grooves 23 , and the second oil grooves 23 are evenly distributed on the lower thrust plate 2 .
[0038] Optionally, the long side width of the second oil groove 23 is equal to the width of the lower thrust plate 2 , and the second oil groove 23 is directly grooved from the lower thrust plate 2 .
[0039] Optionally, a magnetic material is attached to the side of the upper thrust plate 1 that contacts the machine body.
[0040] Optionally, a magnetic material is attached to the side of the lower thrust plate 2 that contacts the machine body.
[0041] In the embodiment of the present application, the two ends of the upper thrust plate and the lower thrust plate are respectively made into a wedge shape and a flat edge, and the flat edge end of the lower thrust plate is designed to protrude from the semicircular rectangular boss structure of the lower thrust plate body, so that when it is misassembled, the anti-misassembly rectangular boss of the lower thrust plate cannot fall into the corresponding countersunk hole of the body, thereby achieving the purpose of preventing and controlling misassembly.
[0042] A magnetic material is arranged on the back side of the upper thrust plate and the lower thrust plate, that is, the side in contact with the machine body. The magnetic material must satisfy the adsorption effect so that the upper thrust plate and the lower thrust plate can be adsorbed on the machine body by relying on the magnetic material on the back when installed on the machine body, thereby achieving the purpose of stable installation.
[0043] In actual situations, it is necessary to avoid fixing the thrust plate when it is installed on the machine body. If it is fixed, the thrust plate will not be able to thrust. Therefore, in actual assembly, the thrust plate is generally fixed to the back side and the machine body by adsorption or adhesion. When the adhesion method is used, grease is generally used as an adhesive. Grease is thicker than lubricating oil and has a certain adsorption capacity. However, in the actual use scenario of grease bonding, the adsorption capacity of the grease applied to the thrust plate before assembly cannot stably allow the thrust plate to fit the thrust plate to the machine body before the machine body assembly is completed. Therefore, in the embodiment of the present application, by arranging a magnetic material for adsorption on the back side of the thrust plate, the assembly state of the thrust plate can be more stable and will not affect the use of the thrust plate in normal working state.
[0044] Specifically, an oil groove is set on the front side of the thrust plate, namely the first oil groove of the upper thrust plate and the second oil groove of the lower thrust plate. In the embodiment of the present application, the number of oil grooves included in the first oil groove and the second oil groove is 2, and the oil grooves are generated by slotting directly above the thrust plate, wherein the positions of the first oil groove and the second oil groove are relative, that is, the slotting positions of the first oil groove and the second oil groove are consistent on the upper thrust plate and the lower thrust plate.
[0045] Specifically, the error-proof rectangular boss extends directly from the lower thrust plate. Therefore, the inner circle of the lower thrust plate presents a complete arc shape, and the outer circle presents a protruding shape. The protrusion of the outer circle is used to correspond to the countersunk hole set in the body for assembling the thrust plate.
[0046] It can be seen from the above technical solutions that this application has the following advantages:
[0047] The present application provides an anti-error rectangular boss and an anti-error wedge structure on the thrust plate, so that the thrust plate cannot be assembled directly when an incorrect assembly occurs. The specific assembly process is firstly to determine the position of the lower thrust plate through the countersunk hole of the body corresponding to the anti-error rectangular boss. At this time, if the upper thrust plate is reversely installed, it will cause the thrust plate to be unable to be assembled, thereby achieving the purpose of correctly assembling the thrust plate.
[0048] The present application also arranges magnetic material on the back sides of the upper thrust plate and the lower thrust plate, so that the upper thrust plate and the lower thrust plate are more stably attached to the body during the assembly process, thereby reducing the situation of abnormal assembly.
[0049] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
