Detailed Description
The invention will be described in further detail with reference to the following detailed description and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary in nature and is in no way intended to limit the scope of the invention or its applications.
Non-limiting and non-exclusive embodiments will be described with reference to the following drawings, in which like reference numerals refer to like elements unless otherwise specified.
The multifunctional engine assembling tray comprises a bottom plate 1, a top plate 2, an engine supporting device, a guide rail 15, a positioning pin 4 and a connecting shaft, wherein a deep groove ball bearing 5 is fixed in the middle of the top plate 2, the upper end of the connecting shaft is connected with the deep groove ball bearing 5, and the lower end of the connecting shaft is fixed in the middle of the bottom plate 1, so that the top plate 2 is rotatably connected with the bottom plate 1. The top plate 2 is provided with 4 first positioning holes for assembling the positioning pins 4, and the 4 first positioning holes Cheng Huanxing are uniformly distributed. The bottom plate 1 is provided with a connecting hole 14 corresponding to the first positioning hole. Thus, when the horizontal angle of the top plate 2 needs to be adjusted, the top plate 2 is rotated to align the first positioning hole of the top plate 2 with the connecting hole of the bottom plate 1, and then the positioning pin 4 is inserted into the first positioning hole and the connecting hole 14 to be locked, so that the horizontal angle of the top plate 2 can be adjusted. The upper surface of the top plate 2 is taken as a mounting surface, and 3 engine supporting devices are arranged in a shape of a Chinese character 'pin', and are respectively arranged on the mounting surface of the top plate 2 in a sliding manner through guide rails 15. Specifically, the engine supporting device comprises sliding plates (10, 16), supporting legs (6, 12) and clamping pins (8, 11), wherein the sliding plates (10, 16) are fixed on a guide rail 15 through bolts, and the supporting legs (6, 12) are vertically fixed on the sliding plates (10, 16) through bolts. The bayonet lock (8, 11) is movably mounted on the slide plate (10, 16). The sliding plates (10, 16) are provided with second positioning holes for assembling the clamping pins (8, 11), and a plurality of pin holes corresponding to the positions of the clamping pins (8, 11) are arranged on the moving track of the clamping pins (8, 11). Thus, after the supporting legs are adjusted according to the supporting requirement of the engine, the lower ends of the clamping pins are inserted into the corresponding pin holes to position the sliding plates (10, 16). The top plate 2 and the bottom plate 1 are rotationally connected through the bearing 5, and when the engine is supported, an operator cannot be guaranteed to press the center of the engine on the bearing 5, so that the bearing 5 and the connecting shaft are subjected to bending stress, and potential safety hazards exist. For increasing roof 2 stability, set up first thrust bearing 13 between roof 2 and bottom plate 1, the up and down terminal surface of first thrust bearing 13 respectively with roof 2 and bottom plate 1 fixed connection, improve the rigidity and the equilibrium of roof 2, effectively avoid roof 2 to lead to roof 2 slope because of the focus skew, the risk that causes the cylinder block to empty.
More specifically, the 3 engine supporting devices are a first supporting device, a second supporting device and a third supporting device respectively. The first supporting device comprises a first sliding plate 16, first supporting feet 12, first clamping pins 11 and guide rails 15, wherein the first sliding plate 16 is a square plate, and two ends of the first sliding plate are respectively fixed on the guide rails 15. The first bayonet 11 is movably disposed in the middle of the first sliding plate, and can move in a direction approaching or separating from the top plate 2. The first supporting legs 12 are respectively arranged at two sides of the first overhead, and the first supporting legs 12 are positioned right above the guide rail 15 so as to prevent the first sliding plate 16 from being deformed under pressure.
The second supporting device comprises a second sliding plate 10, second supporting feet 6, second clamping pins 8 and guide rails 15, wherein the second sliding plate 10 is of a Z-shaped structure and is fixed on the guide rails 15 through bolts, the second supporting feet 6 are fixed on the upper surface of the second sliding plate 10, and engine foot positioning pins 7 are arranged on the top surfaces of the second supporting feet 6. The second bayonet lock 8 is movably mounted at the end of the second slide plate 10.
In the above embodiment, the first bayonet 11, the second bayonet 8, and the positioning pin 4 have the same structure and are spring pin structures for convenience of use. In a normal state, the first bayonet lock 11, the second bayonet lock 8 and the positioning pin 4 all tend to move towards the direction of the bottom plate 1 under the action of elastic force. How the dowel 4 realizes the characteristics of an elastic pin is described by taking the way the dowel 4 is fixed as an example. Specifically, referring to fig. 4, the device comprises a shaft sleeve 81, a screw cover 87, a spring 83 and a handle 84, wherein the shaft sleeve 81 is welded and fixed outside the first positioning hole, and the inner diameter of the shaft sleeve is the same as the diameter of the first positioning hole. The inner wall of the sleeve 81 is provided with a rotation stopping groove 82 along the axial direction thereof, and the rotation stopping groove 82 extends to the lower part of the top plate 2. Correspondingly, the side wall of the positioning pin 4 is provided with a rotation stopping column 85 which is matched with the rotation stopping groove 82 in width, and the upper part of the positioning pin 4 is of a stepped column structure. When the positioning pin 4 is mounted, the positioning pin 4 is inserted along the upper end of the boss 84, and the rotation stopping post 85 is caught in the rotation stopping groove 82 so that the rotation stopping post 85 abuts against the bottom of the rotation stopping groove 82. Then, the step column part at the upper part of the positioning pin 4 is sleeved with the spring 83, the screw cover 87 is screwed into the top of the shaft sleeve 81 in a threaded connection mode, and the middle part of the screw cover 87 is provided with a perforation, so that the upper part of the positioning pin 4 penetrates out of the perforation to straighten the outer side of the screw cover 87. After the screw cap 87 is screwed in this way, the lower end of the spring 83 abuts against the stepped surface 88 on the upper portion of the positioning pin 4, the upper end abuts against the screw cap 87, the spring 83 is made to exert elastic force on the positioning pin 4, and the positioning pin 4 tends to move toward the bottom plate 1 due to the elastic force. Meanwhile, in order to facilitate lifting of the positioning pin 4, a handle 84 is screwed on the top of the positioning pin 4. The first bayonet 11 and the second bayonet 8 have substantially the same locking structure as the positioning pin 4, except that the top plate is replaced with a first slide plate 16 and a second slide plate 10 corresponding thereto.
The front end and the rear end of the bottom plate 1 are respectively provided with an anti-collision block 3 for buffering collision. In order to facilitate the movement of the tray, hanging rings are connected with the periphery of the top plate in a threaded manner.
In the above-described technical solution, although the production is basically required, the positioning pin 4 needs to be taken out when the top plate 2 is rotated, and the positioning pin 4 is inserted into the locking position after the top plate 2 is rotated in place. Since the positioning pin 4 needs to be taken out when the top plate 2 is rotated, in order to avoid the interference of the engine on the taking out of the positioning pin 4, the bottom plate 1 and the top plate 2 need to be enlarged, but the space of the engine assembly line is limited, and the positioning pin 4 is inconvenient to take out and put after the bottom plate 1 and the top plate 2 are enlarged. In order to solve the defect that the positioning pin 4 is inconvenient to take and place, a set of positioning pin jacking device is designed and the structure of the positioning pin 4 is improved, so that the positioning pin 4 can be lifted under the condition that the state of the positioning pin 4 is not observed, and the positioning pin 4 does not need to be taken out of the first positioning hole. Referring to fig. 5-8, the locating pin jacking device is arranged between the bottom plate 1 and the top plate 2, and comprises a second thrust bearing 51, a cambered surface trapezoidal piece 53, a link mechanism and a connecting rod 52, wherein a lower thrust washer of the second thrust bearing 51 is fixed with the bottom plate 1, an upper thrust washer end face is spaced from the top plate 2, and the second thrust bearing 51 is coaxial with the deep groove ball bearing 5. The second thrust bearing 51 and the first thrust bearing 13 are coaxial, and the diameter of the second thrust bearing is larger than that of the first thrust bearing 13, so that the positioning pin 4 is positioned between the first thrust bearing 13 and the second thrust bearing 51, and the height of the second thrust bearing 51 is lower than that of the first thrust bearing 13, so that the second thrust bearing 51 is prevented from interfering with the rotation of the top plate 2. The link mechanism is hinged with an upper thrust washer of the second thrust bearing 51, and the link mechanism is utilized to enable the second thrust bearing 51 to rotate back and forth within a certain range. The connecting rod is of an L-shaped structure, one end of the connecting rod is fixed with the upper thrust washer of the second thrust bearing 51, and the other end of the connecting rod is fixed with the cambered surface trapezoidal piece 53. Correspondingly, the lower part of the positioning pin 4 is provided with cambered surface abdication grooves 86 penetrating through two sides of the positioning pin, and the cambered surface abdication grooves 86 are arranged along the axial direction of the positioning pin 4 from the lower end surface of the positioning pin. In actual use, the cambered surface trapezoidal piece 53 corresponds to the cambered surface abdication groove 86 in position, and the cambered surface diameters of the cambered surface trapezoidal piece and the cambered surface abdication groove are the same. In order to avoid excessive friction between the cambered surface trapezoidal piece 53 and the cambered surface abdication groove 86, the width of the cambered surface abdication groove 86 is designed to be larger than the thickness of the cambered surface trapezoidal piece 53. The connecting rod 52 is formed in an L-shaped structure so that the bottom of the cambered surface trapezoidal piece 53 is as close to the bottom plate 1 as possible. In order to reduce the friction force between the relief groove 86 and the cambered surface trapezoidal piece 53, the contact position between the top of the relief groove 86 and the cambered surface trapezoidal piece 53 is designed to be a rounded corner. The lower end surface of the positioning pin 4 is made into a spherical surface, so that the positioning pin can be conveniently and rapidly inserted into the connecting hole 14.
More specifically, the cambered trapezoid piece 53 is disposed on the inner side of the second thrust bearing 51, is high in the middle and is inclined toward both ends, and has an isosceles trapezoid or approximately isosceles trapezoid structure. To accommodate the circumferential movement of the positioning pin 4, the side surface of the arc-shaped trapezoidal piece 53 is set to be an arc surface with the same diameter as the circumference 54 of the positioning pin 4. In actual use, the positioning pin 4 moves towards the base plate 1 under the elastic force of the spring 83, and after the positioning pin 4 is inserted into the connecting hole 14 of the base plate 1 to be in place, the top of the yielding groove 86 of the positioning pin 4 is higher than the horizontal plane of the base plate 1. Thus, when the link mechanism is driven to rotate the second thrust bearing 51, the cambered surface trapezoidal piece 53 can be inserted into the relief groove 86, so that the positioning pin 4 is slowly ejected out of the connecting hole 14 of the bottom plate 1. In order to avoid the connecting rod 52 interfering with the movement of the positioning pin 4, the connecting rod 52 is fixed in the middle of the bottom of the cambered surface trapezoidal piece 53, and when the positioning pin 4 is positioned on the top surface of the cambered surface trapezoidal piece 53, the lower end of the positioning pin 4 is above the horizontal plane of the connecting rod 52 (as shown in fig. 7 and 8), so that the interference of the connecting rod 52 on the positioning pin 4 can be effectively avoided.
In this embodiment, the number of the connecting holes 14 is 4, and the 4 cambered trapezoidal pieces are respectively matched with the 4 connecting holes 14, so that no matter which connecting hole 14 the positioning pin 4 is inserted into, the positioning pin can be ejected out of the connecting hole 14 by utilizing the cambered trapezoidal pieces 53. Because the locating pin 4 is provided with the abdication groove 86, 2 locating pins 4 are arranged for cooperation use in order to strengthen the function of the locating pin 4 rotation-stopping top plate 2.
In addition, the present embodiment may adopt various forms of linkage mechanisms to drive the second thrust bearing 51 to reciprocate within a certain range, with the aim of reciprocating through the second thrust bearing 51, so that the cambered trapezoid pieces 53 are far from or near to the adjacent connecting holes 14, thereby ejecting the positioning pins 4 out of the connecting holes 14. Specifically, in this embodiment, the link mechanism includes a second guide rail 64, a first link 61, a second link 63, a first stopper 62, and a second stopper 65, where one end of the first link 61 is hinged to the outer side of the upper thrust washer of the second thrust bearing 51, and the other end is hinged to the second link 63, and the middle part of the second link 63 is welded and fixed on the slider of the second guide rail 64. By moving the slider back and forth on the stroke of the second guide rail 64, the second connecting rod 63 drives the first connecting rod 61 to pull the second thrust bearing 51 to do reciprocating rotation within a certain range. In order to enable an operator to accurately know that the positioning pin 4 is completely ejected out of the connecting hole 14, the first limiting block 62 and the second limiting block 65 are welded and fixed on the second connecting rod 63, and the second guide rail 64 is located between the first limiting block 62 and the second limiting block 65. When the second connecting rod 63 is pulled, and the first limiting block 62 moves towards the second guide rail 64, the cambered trapezoid piece 53 gradually approaches to the adjacent connecting hole 14, so that the positioning pin 4 is slowly ejected out; when the second stopper 65 moves in the direction of the second guide rail 64, the cambered surface trapezoidal piece 53 gradually gets away from the connecting hole 14. The second guide rail 64 is fixed on the bottom plate 1, so that the operation is convenient, and the operation of the production line is not disturbed. The second guide rail is perpendicular to the second thrust bearing 51.
Those skilled in the art will recognize that numerous variations are possible in light of the above description, and that the examples and figures are presented for the purpose of describing one or more particular embodiments only.
While there have been described and illustrated what are considered to be example embodiments of the present invention, it will be understood by those skilled in the art that various changes and substitutions can be made therein without departing from the spirit of the invention. In addition, many modifications may be made to adapt a particular situation to the teachings of the invention without departing from the central concept thereof as described herein.
