Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly lines, in particular to a balancing device mechanism. Background Art

[0002] With the development of the automotive industry and the increasing demand for automobiles by consumers, the processing and production efficiency of the automotive industry has always been the pursuit of automobile companies. At present, automotive parts pressing components are required in the production and assembly of automotive parts. The existing method is to use a three-position five-way center drain valve to exhaust the air inside the pressure cylinder after activation to enable the mechanism to move. When this method is installed in the vertical direction of the mechanism, after exhausting the air using the three-position five-way solenoid valve, the mechanism will fall rapidly due to its own weight, which is not conducive to the operator's assembly of parts. At the same time, it is not conducive to the synchronous movement of the upper pressure head and the lower positioning tooling, affecting the pressing effect.

[0003] For example, Chinese patent (CN220373173U) discloses an automobile parts press-fitting assembly, which includes a fixed frame, a guide rail, a connecting frame, a tool positioning frame and a limit frame. A press is provided on the fixed frame; the guide rail is provided on the fixed frame, and the press is provided at the end of the guide rail, and the extension direction of the guide rail is consistent with the downward pressing direction of the press; the connecting frame is provided on the press, and a pressure head is movably connected to the connecting frame; the tool positioning frame is provided on the guide rail and can be moved along the extension direction of the guide rail, and automobile parts can be installed on the tool positioning frame; the limit frame is provided at the end of the guide rail away from the press, and when the press is pressed down, the limit frame limits the movement of the tool positioning frame. This utility model can realize the press-fitting of various products by using a set of pressure piles in combination with a set of presses, only by replacing the pressure head and the workpiece positioning plate, saving costs, improving efficiency, accurate positioning, and smooth operation.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for balancing the weight of the pressure head itself. Due to the effect of the pressure head's own weight, the pressure head will fall rapidly when pressing down, and it is difficult for the staff to make the pressure head hover at any position. For semi-automatic equipment, the staff needs to rely on manpower to overcome the weight of the pressure head, thereby increasing the staff's operating load. For fully automatic equipment, due to the influence of the pressure head's own weight, it is difficult to synchronize the pressure head and the lower positioning work, thereby affecting the effect of part pressing.

[0032] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 5 A balancing device mechanism in this embodiment includes a bracket 1, a downward pressure cylinder 2 is installed on the bracket 1, a press-fit assembly 300 is installed at the telescopic end of the downward pressure cylinder 2, a pressure reducing valve 4 is provided on the bracket 1, and the downward pressure cylinder 2 is connected to the pressure reducing valve 4.

[0034] The press-fitting assembly 300 in this embodiment is used to drive the parts that need to be press-fitted to be pressed downward, so as to install the parts on the products that need to be assembled. The lower positioning tool 500 is used to position the products that need to be assembled, so as to facilitate the alignment of the parts that need to be press-fitted with the products that need to be assembled. The pressure reducing valve 4 can slow down the exhaust speed of the pressing cylinder 2 when the exhaust speed of the pressing cylinder 2 is too fast, and at the same time can increase the exhaust speed of the pressing cylinder 2 when the exhaust speed of the pressing cylinder 2 is too slow, so that the pressure reducing valve 4 can balance the gravity of the press-fitting assembly 300 itself by adjusting the exhaust speed of the pressing cylinder 2, thereby facilitating the control of the press-fitting assembly to hover at any position, and thus making the parts more accurately press-fitted on the products that need to be assembled.

[0035] It should be noted that the pressure reducing valve 4 is a relief type pressure reducing valve.

[0036] Please refer to Figure 1 and Figure 5 In this embodiment, the bracket 1 is provided with a first throttle valve 11, a second throttle valve 12 and a solenoid valve 10. The output end of the solenoid valve 10 is connected to the input end of the first throttle valve 11 through an air guide pipe. The output end of the first throttle valve 11 is connected to the air inlet of the downward pressure cylinder 2, and the exhaust port of the downward pressure cylinder 2 is connected to the input end of the second throttle valve 12. The output end of the second throttle valve 12 is connected to the input end of the pressure reducing valve 4, and the pressure reducing valve 4 is connected to the input end of the solenoid valve 10.

[0037] In this embodiment, the first throttle valve 11, the second throttle valve 12 and the solenoid valve 10 are all installed on the left side wall of the bracket 1. The first throttle valve 11 is used to control the air intake speed of the downward pressure cylinder 2, and the second throttle valve 12 is used to control the air outlet speed of the downward pressure cylinder 2, thereby realizing the adjustment of the extension and contraction speed of the downward pressure cylinder 2. The solenoid valve 10 is used to realize terminal control of the inlet and outlet of gas. The model of the solenoid valve 10 is SY5420-5LOZD-01.

[0038] Please refer to Figures 1 to 3 In this embodiment, a mounting plate 8 is provided between the downward-pressing cylinder 2 and the pressing assembly 300. One side of the mounting plate 8 is connected to the telescopic end of the downward-pressing cylinder 2, and the other side of the mounting plate 8 is connected to the rotating cylinder 9. The executing end of the rotating cylinder 9 is connected to the pressing assembly 300. The bracket 1 is also provided with a second guide rod connected to the mounting plate 8. The mounting plate 8 is also provided with a valve control button 7. The pressing assembly 300 includes a pressure head 301 connected to the executing end of the rotating cylinder 9, and a plurality of connecting rods 302 connected to the mounting plate 8. The bottom end of the connecting rod 302 is connected to a connecting plate 303. An anti-lifting component is provided on the side of the connecting plate 303, and a movable hole is opened in the middle of the connecting plate 303 for the pressure head 301 to pass through. The anti-lifting component includes multiple first guide rods 305 and an anti-lifting pressure plate 306 connected to the first guide rods 305. The first guide rods 305 are arranged parallel to the central axis of the pressure head 301 and are connected to the connecting plate 303 through a first linear bearing 304. Ear plates are provided on both sides of the connecting plate 303, and the first linear bearing 304 is installed in the ear plates; a spring is sleeved on the outer periphery of the first guide rod 305, and the spring is located between the ear plate and the anti-lifting pressure plate 306.

[0039] The rotating cylinder 9 in this embodiment is used to drive the pressure head 301 to rotate and press down, so that the pressure head 301 can install the parts on the product to be assembled. The connecting rod 302 is used to fix the connecting plate 303, so as to facilitate the installation of the first guide rod 305 and the anti-strip pressure plate 306. The anti-strip pressure plate 306 abuts against the parts to separate the parts and the pressure head 301, thereby preventing the pressure head from moving up with the already pressed parts and the products to be pressed together during the upward movement. The spring is used to deform when the part squeezes the anti-strip pressure plate 306. The elastic force generated by the deformation of the spring can push the parts and the pressure head 301 to separate.

[0040] It should be noted that the valve control button 7 is used to control the start and close of the solenoid valve 10, and the mounting plate 8 can facilitate the connection between the rotating cylinder 9 and the pressing cylinder 2, so that the pressing cylinder 2 can drive the rotating cylinder 9 to move downward.

[0041] Please refer to Figures 1 to 3 In this embodiment, a lower positioning tool 500 is provided below the press-fitting assembly 300 for use therewith. The lower positioning tool 500 includes a positioning plate 501, a plurality of positioning rods 503 are provided on the positioning plate 501, and a handle 502 is provided on the side of the positioning plate 501.

[0042] The lower positioning fixture 500 in this embodiment is used to fix the product to be assembled, and the positioning rod 503 fixes the product by being inserted into the interior of the product to be assembled, thereby facilitating the alignment of the parts and the product.

[0043] Operation method: when it is necessary to press-fit the parts, install the parts to be press-fitted on the pressure head 301, place the products to be assembled on the positioning rod 503, press the valve control button 7, the valve control button 7 controls the solenoid valve 10 to start, the solenoid valve 10 introduces the gas into the first throttle valve 11, the first throttle valve 11 adjusts the flow rate of the gas, and then the gas enters the downward pressure cylinder 2, the downward pressure cylinder 2 drives the mounting plate 8 to move downward, the mounting plate 8 drives the rotating cylinder 9 and the press-fitting assembly 300 to move downward, when the downward pressure cylinder 2 accelerates downward under the action of the self-gravity of the press-fitting assembly 300, the rotating cylinder 9 and the mounting plate 8, the speed at which the gas enters the downward pressure cylinder 2 is accelerated, at this time the pressure reducing valve 4 adjusts the flow rate of the gas, the pressure reducing valve 4 accelerates the speed at which the gas is discharged from the second throttle valve 12 to achieve the balance of the gravity of the press-fitting assembly 300, the rotating cylinder 9 and the mounting plate 8; the rotating cylinder 9 drives the pressure head 301 and the parts to press downward, and at the same time The mounting plate 8 drives the second guide rod 602 to slide in the second linear bearing 601. When the pressure head 301 presses the part to be press-fitted onto the product to be assembled, the solenoid valve 10 is closed, the downward pressure cylinder 2 stops driving the rotating cylinder 9 and the press-fitting assembly to move downward, and the rotating cylinder 9 is started. The rotating cylinder 9 drives the part to rotate, and the part is installed on the product to be assembled. After the press-fitting is completed, the rotating cylinder 9 is started in the reverse direction, and the rotating cylinder 9 drives the pressure head 301 to move upward. When a part moves upward with the pressure head 301, the anti-slip pressure plate 306 blocks the part, and the part squeezes the anti-slip pressure plate 306. The anti-slip pressure plate 306 compresses the spring to deform it. When the elastic force of the spring is sufficient to separate the part from the pressure head 301, the part falls from the pressure head 301, and the spring drives the anti-slip pressure plate 306 to reset. Then the solenoid valve 10 is started, and the downward pressure cylinder 2 drives the mounting plate 8, the rotating cylinder 9 and the press-fitting assembly 300 to reset.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
