DETAILED DESCRIPTION
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] As we all know, automobile engine cooling water pump is a key component of automobile engine, and its normal working speed is about 3000n / min. The precision of water pump parts and assembly precision directly affect the noise and vibration of engine during operation. The hub and impeller of water pump are pressed and assembled by fixed tooling traditionally. Due to the existence of axial height tolerance during hub and impeller processing, as well as the axial tolerance of bearing and height tolerance of water pump housing, their cumulative error is normally above 0.5mm, and the axial clearance of bearing is normally between 0.03mm-0.18mm, and their accumulation cannot be completely eliminated.
[0026] After assembly, the water pump shaft will feel bad when rotating, mainly due to "beating" and heavy rotation. "Beat" is because the bearing raceway is damaged during the press-fitting process, and the heavy feeling is because all the bearing clearances are eliminated. The former will cause greater vibration and noise in the engine during use, and the latter will cause overheating of the bearing, which will eventually lead to premature damage to the bearing and loss of water pump function.
[0027] The utility model provides Figures 1 to 5 An automatically adjusted double-point floating support device is shown, comprising a mounting plate 1, a bottom plate 102 is mounted on the bottom end of the mounting plate 1, a plurality of clamping plates 101 are mounted on the end surface of the mounting plate 1, a water pump plugging cover 2 is mounted between the clamping plates 101 and the mounting plate 1, a supporting device is arranged on the top end of the bottom plate 102, and the supporting device is used to support the water pump plugging cover 2.
[0028] When in use, the mounting plate 1 and the base plate 102 form an L shape, the clamping plate 101 of the mounting plate 1 clamps the water pump plugging cover 2, and the supporting device of the base plate 102 supports the lower end surface of the water pump plugging cover 2, while adjusting the angle of the water pump plugging cover 2.
[0029] The supporting device comprises a cylinder seat 103 and a frame 4 . The cylinder seat 103 and the frame 4 are both mounted on the top of the bottom plate 102 . The cylinder 3 is mounted on one end of the cylinder seat 103 .
[0030] When in use, the cylinder seat 103 is used for installing the cylinder 3, and the frame 4 is used for installing and fixing the supporting components.
[0031] An inclined sliding seat 6 is arranged inside the frame 4, the telescopic end of the cylinder seat 103 is connected to the inclined sliding seat 6, a guide block 7 is arranged at the top of the inclined sliding seat 6, and blocks 8 are arranged on both sides of the frame 4. There are two blocks 8, and the block 8 is located on both sides of the frame 4. The guide block 7 is located between the two blocks 8.
[0032] When in use, the cylinder 3 drives the inclined sliding seat 6 to slide inside the frame 4. When the inclined sliding seat 6 slides, the guide block 7 and the inclined sliding seat 6 make relative movement, and the processing accuracy and assembly accuracy are high. Because the inclined sliding seat 6 slides to the side away from the cylinder 3, the inclined sliding seat 6 squeezes the guide block 7 to move during the sliding process. There are block blocks 8 on both sides of the guide block 7 to limit the position of the guide block 7 to prevent the guide block 7 from escaping from the interior of the frame 4 and affecting the use of the device.
[0033] A double-point auxiliary support platform 9 is provided at the top end of the guide block 7 .
[0034] When in use, the guide block 7 drives the double-point auxiliary support platform 9 to move.
[0035] The bottom end of the guide block 7 and the top end of the inclined sliding seat 6 are matched with each other in an inclined surface, and the bottom end of the guide block 7 and the top end of the inclined sliding seat 6 are fitted and connected.
[0036] The end surface of the frame body 4 is provided with a waist-shaped hole, and a cylindrical pin 5 is arranged inside the waist-shaped hole. The cylindrical pin 5 is used to penetrate the semicircular protrusion 902 and engage with the waist-shaped hole.
[0037] When in use, the inclined lower part of the guide block 7 fits with the inclined higher part of the top end of the inclined sliding seat 6, and the inclined higher part of the guide block 7 fits with the inclined lower part of the top end of the inclined sliding seat 6. When the inclined sliding seat 6 moves, the inclined higher part of the top end slides toward the inclined lower part of the guide block 7, and the inclined higher part of the top end of the inclined sliding seat 6 squeezes the inclined bottom end of the guide block 7. The inclined angle between the inclined sliding seat 6 and the guide block 7 is less than 5. The position of the guide block 7 is limited by the stop block 8, forcing the guide block 7 to move upward, driving the double-point auxiliary support platform 9 to contact and support the water pump plug cover 2.
[0038] The guide block 7 drives the double-point auxiliary support platform 9 to move. The upward movement range of the guide block 7 is the same as the length of the waist-shaped hole. The cylindrical pin 5 slides in the waist-shaped hole to clamp the double-point auxiliary support platform 9 and at the same time to limit the rising height of the double-point auxiliary support platform 9.
[0039] A groove 701 is formed at the top of the guide block 7 .
[0040] The double-point auxiliary support platform 9 includes a support base 901 , a semicircular protrusion 902 is arranged at the bottom end of the support base 901 , and a first support column 903 and a second support 904 are arranged on both sides of the top end of the support base 901 .
[0041] The first support 903 is higher than the second support 904 .
[0042] The semicircular protrusion 902 is connected to the groove 701 at the top end of the guide block 7 .
[0043] When in use, the groove 701 of the guide block 7 is used to install the semicircular protrusion 902. The support seat 901 is connected to the arc surface of the semicircular protrusion 902 through the groove 701. At the same time, the cylindrical pin 5 is the fulcrum of the semicircular protrusion 902. The semicircular protrusion 902 rotates around the cylindrical pin 5 to achieve automatic alignment and support at the same time.
[0044] The first support 903 and the second support 904 have different heights, and the groove 701 is connected to the arc surface of the semicircular protrusion 902. When the guide block 7 rises and contacts the water pump plugging cover 2, due to the different heights of the first support 903 and the second support 904, the height difference causes the support seat 901 to rotate around the cylindrical pin 5, so that the first support 903 and the second support 904 both contact the water pump plugging cover 2 and provide support.
[0045] Working principle: the water pump plugging cover 2 is mounted on the end surface of the mounting plate 1, and the water pump plugging cover 2 is clamped by the clamping plate 101. After clamping, the supporting device of the bottom plate 102 supports the water pump plugging cover 2.
[0046] The frame 4 and the cylinder seat 103 are mounted on the end surface of the bottom plate 102 , and the mounting plate 1 and the bottom plate 102 form an L shape, which is convenient for the supporting device to support the water pump plug cover 2 .
[0047] The cylinder 3 drives the inclined sliding seat 6 to slide, and the sliding direction is away from one end of the cylinder 3. When the inclined sliding seat 6 slides, the guide block 7 and the inclined sliding seat 6 make relative movement, and the lower inclined part of the guide block 7 fits with the higher inclined part of the top of the inclined sliding seat 6, and the higher inclined part of the guide block 7 fits with the lower inclined part of the top of the inclined sliding seat 6. When the inclined sliding seat 6 moves, the higher inclined part of the top slides toward the lower inclined part of the guide block 7, and the higher inclined part of the top of the inclined sliding seat 6 squeezes the lower inclined part of the guide block 7. The inclined angle between the inclined sliding seat 6 and the guide block 7 is less than 5, and the guide block 7 is limited in position by the stopper 8, forcing the guide block 7 to move upward, driving the double-point auxiliary support platform 9 to contact and support the water pump plug cover 2. During the sliding process, the inclined sliding seat 6 squeezes the guide block 7 to move, and there are stoppers 8 on both sides of the guide block 7 to limit the position of the guide block 7, so as to prevent the guide block 7 from escaping from the interior of the frame 4 and affecting the use of the device.
[0048] The groove 701 of the guide block 7 is used to install the semicircular protrusion 902. The support seat 901 is connected to the arc surface of the semicircular protrusion 902 through the groove 701. At the same time, the cylindrical pin 5 is the fulcrum of the semicircular protrusion 902. The semicircular protrusion 902 rotates around the cylindrical pin 5 to achieve automatic alignment and support at the same time.
[0049] The first support 903 and the second support 904 have different heights, and the groove 701 is connected to the arc surface of the semicircular protrusion 902. When the guide block 7 rises and contacts the water pump plugging cover 2, due to the different heights of the first support 903 and the second support 904, the height difference causes the support seat 901 to rotate around the cylindrical pin 5, so that the first support 903 and the second support 904 both contact the water pump plugging cover 2 and provide support.
[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
