Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical assembly technology, and in particular to an engine mount assembly fixture. Background Technology
[0002] Engine hydraulic mounts are support and vibration damping components connecting the engine and the vehicle body. They isolate engine vibrations and noise from being transmitted into the passenger compartment, significantly improving overall vehicle comfort. Engine mount cups are used to seal the fluid within the engine hydraulic mounts. The fluid's function is to enhance vibration damping and sound insulation through its flow, reducing engine vibration frequency and minimizing resonance. In addition to sealing the fluid in the engine hydraulic mounts, the cups can also absorb changes in volume within the engine mount cavity through deformation. During assembly, components such as the cup, cup clamping ring, nylon flow channel, and flow channel cover are typically installed onto the main spring to form the main spring assembly. The main spring assembly is then installed onto the housing. However, after the cup is installed onto the main spring using the cup clamping ring, the edge of the cup is compressed, causing the center of the cup to bulge. During the subsequent installation of the main spring assembly onto the housing, the housing interferes with the bulging part of the cup, and may even cause the cup to be clamped at the connection between the housing and the main spring assembly. This can lead to deformation or even breakage of the cup, resulting in cup failure and ultimately scrapping the entire product. It also affects assembly efficiency. Utility Model Content

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] See Figures 1 to 5 This utility model provides an engine mount assembly fixture, characterized in that it includes:
[0028] The support base 1 is provided with a first positioning part 101 and an air intake 102. The first positioning part 101 is used to place the main spring assembly 9, and the air intake 102 is used to communicate with the air hole 901 of the main spring assembly 9. An air intake channel 103 is opened inside the support base 1, and the air intake channel 103 is connected to the air intake 102.
[0029] The air intake mechanism 2 is connected to the air intake channel 103;
[0030] Positioning block 3, wherein a second positioning part 301 is provided on the positioning block 3, the second positioning part 301 is used to place the housing, and the position of the second positioning part 301 corresponds to the position of the first positioning part 101;
[0031] The upper pressure plate 4 is provided with a pressure block 401, the position of which corresponds to the position of the second positioning part 301.
[0032] This utility model embodiment provides an engine mount assembly fixture, including: a support base 1, an air intake mechanism 2, a positioning block 3, and an upper pressure plate 4. In the main spring assembly 9, there is a cavity between the cup and the main spring. The cavity is connected to the air hole of the main spring assembly 9. During assembly, the main spring assembly 9 is placed on the first positioning part 101, and the air intake nozzle 102 abuts against the air hole of the main spring assembly 9, so that the air intake channel 103 is connected to the cavity. The air intake mechanism 2 is activated, and the gas in the cavity is extracted through the air intake channel 103 to form a negative pressure environment, ensuring that the concave part of the cup fits the main spring. Then, the housing is placed on the positioning part. After the housing and the main spring assembly 9 are aligned, the upper pressure plate 4 is pressed down, so that the main spring assembly 9 is inserted into the housing. The air intake mechanism 2 stops working, the upper pressure plate 4 rises, and the operator removes the workpiece. By setting the suction mechanism 2, the bulging of the middle of the leather cup can be avoided, thereby preventing interference between the shell and the leather cup during assembly, thus preventing leather cup failure, ensuring product quality, and improving assembly efficiency.
[0033] In a further embodiment of this invention, the suction mechanism 2 includes a vacuum generator 201 and an air pipe 202. An air pipe connector 104 is provided on the support base 1. The vacuum generator 201 includes an air inlet 203, an air outlet 204, and a suction port 205. The air inlet 203 is used to communicate with an external air source. The suction port 205 is connected to the suction channel 103 through the air pipe 202. The air pipe connector 104 is connected to the suction channel 103 and the air pipe connector 104 is connected to the air pipe 202.
[0034] In this embodiment, the vacuum generator 201 includes an air inlet 203, an air outlet 204, and a suction port 205. When suction is required, high-pressure gas blown from an external air source enters through the air inlet 203 and exits through the air outlet 204, ensuring a negative pressure state between the suction port 205 and the suction channel 103. This allows for the adsorption of the rubber cup, preventing bulging in the center of the rubber cup and avoiding interference between the housing and the rubber cup during assembly. This ensures the sealing and vibration damping performance of the finished product and improves assembly efficiency. By using the vacuum generator 201 in conjunction with an external air source, a negative pressure environment is created in the suction channel 103. This design is simple and can directly utilize the air source on the production line without the need for additional electric suction equipment, significantly reducing costs. Furthermore, this fixture is easy to operate; operators can complete the assembly with just a few simple steps, reducing the need for skilled workers and shortening the production cycle.
[0035] In a further embodiment of this invention, the diameter of the air outlet 204 is greater than or equal to the diameter of the air inlet 203.
[0036] In this embodiment, the diameter of the air outlet 204 is greater than or equal to the diameter of the air inlet 203, so that the gas flow rate in the air inlet 203 is greater than the gas flow rate in the air outlet 204. The air intake 205 is connected to the air inlet 203, thereby forming a stronger negative pressure environment and more effectively adsorbing the rubber cup. When high-pressure gas flows from the air inlet 203 to the air outlet 204, its volume expands, causing the pressure to drop, further enhancing the negative pressure effect, ensuring that the rubber cup fits the main spring, and further avoiding interference between the shell and the rubber cup during assembly. This avoids the rubber cup from failing, ensuring the quality of the finished product and improving assembly efficiency.
[0037] In a further embodiment of this invention, the angle between the axis of the air intake hole 205 and the axis of the air inlet hole 203 is less than or equal to 90°.
[0038] In this embodiment, the angle between the axis of the air intake hole 205 and the axis of the air inlet hole 203 is less than or equal to 90°, and the air inlet hole 203 and the air outlet hole 204 are coaxially arranged. This layout ensures smooth gas flow, avoids unnecessary resistance when high-pressure gas flows, and prevents high-pressure gas from flowing into the air intake hole 205 and affecting the negative pressure environment in the air intake channel 103. This ensures that the rubber cup fits the main spring, further avoids interference between the housing and the rubber cup during assembly, and thus avoids rubber cup failure, ensuring the quality of the finished product and improving assembly efficiency.
[0039] In a further embodiment of this invention, the suction mechanism 2 further includes a muffler 206, which is connected to the air outlet 204 of the vacuum generator 201.
[0040] In this embodiment, the silencer 206 is connected to the air outlet 204 of the vacuum generator 201. When high-speed gas is discharged, it effectively reduces noise and improves the comfort of the working environment. At the same time, it does not affect the negative pressure effect, ensuring stable adsorption of the leather cup, further optimizing the assembly process and improving production efficiency.
[0041] In a further embodiment of this invention, the engine mount assembly fixture further includes a clamping mechanism 5, which includes a clamping cylinder 501 and a clamping block 502. The clamping cylinder 501 is throttle-connected to the clamping block 502, and the clamping block 502 corresponds to the position of the first positioning part 101. The clamping block 502 is used to place the main spring assembly 9.
[0042] In this embodiment, the clamping mechanism 5 includes a clamping cylinder 501 and a clamping block 502. During assembly, the main spring assembly 9 is placed on the first positioning part 101 and the clamping block 502. The clamping cylinder 501 is activated to push the clamping block 502 to move rapidly, achieving precise clamping of the main spring assembly 9. The clamping block 502, in cooperation with the positioning part, ensures the stability of the main spring assembly 9 during the assembly process, improving assembly accuracy and speed. The clamping cylinder 501 can share an external air source with the suction mechanism 2, further simplifying equipment configuration and reducing costs. The efficient response of the clamping cylinder 501 ensures the continuity of the assembly process, avoiding assembly errors caused by unstable clamping, thereby improving overall production efficiency and product quality.
[0043] In a further embodiment of this invention, the engine mount assembly fixture further includes a lower base plate 6, and the clamping mechanism 5 further includes a clamping slide rail 503. The clamping slide rail 503 is disposed on the lower base plate 6, and the clamping block 502 is slidably disposed on the clamping slide rail 503.
[0044] In this embodiment, the clamping block 502 is slidably disposed on the clamping slide rail 503. Through the guiding effect of the clamping slide rail 503, the clamping block 502 is made more stable during movement, which further ensures the stability of the main spring assembly 9 during the assembly process and improves the assembly accuracy and speed.
[0045] In a further embodiment of this invention, the engine mount assembly fixture further includes a lower base plate 6 and a telescopic stabilizer 7. The first end of the telescopic stabilizer 7 is fixedly connected to the lower base plate 6, and the second end of the telescopic stabilizer 7 is fixedly connected to the upper pressure plate 4.
[0046] In this embodiment, the first end of the telescopic stabilizing column 7 is fixedly connected to the lower base plate 6, and the second end of the telescopic stabilizing column 7 is fixedly connected to the upper pressure plate 4. During assembly, as the upper pressure plate 4 is pressed down, the telescopic stabilizing column 7 effectively prevents the upper pressure plate 4 from tilting during the pressing process, ensuring the stability of the assembly process. This can further improve the assembly accuracy and ensure the quality and performance of the suspension device.
[0047] In a further embodiment of this invention, the telescopic stabilizing column 7 includes a stabilizing column body 701 and a stabilizing sleeve 702. One end of the stabilizing column body 701 is inserted into the stabilizing sleeve 702, and the other end of the stabilizing column body 701 is fixedly connected to the lower base plate 6. The end of the stabilizing sleeve 702 is fixedly connected to the upper pressure plate 4.
[0048] In this embodiment, the telescopic stabilizing column 7 includes a stabilizing column 701 and a stabilizing sleeve 702. The structure is simple and reliable. This design ensures that even when subjected to forces in different directions during assembly, the telescopic stabilizing column 7 can effectively support the upper pressure plate 4, ensuring that it does not sink or tilt, thereby guaranteeing the accuracy and stability of the suspension device assembly.
[0049] In a further embodiment of this invention, a guide post 8 is provided on the lower base plate 6, the end of the guide post 8 is fixedly connected to the lower base plate 6, the positioning block 3 is slidably disposed on the guide post 8, and a reset spring 801 is provided between the positioning block 3 and the lower base plate 6, the reset spring being sleeved on the guide post 8.

During assembly, the upper pressure plate 4 presses down, and the pressure block 401 presses against the housing placed on the positioning block 3, causing the main spring assembly 9 to be inserted into the housing. During this process, the positioning block 3 positions the housing, ensuring its accuracy. Through the action of the return spring 801, the positioning block 3 can quickly return to its original position after the upper pressure plate 4 is lifted, preparing for the next assembly, thereby improving overall work efficiency.
