AI Technical Summary
In automobile production, the mounting arms of the left and right aluminum brackets are eccentric to the left and right respectively relative to the axis of the hydraulic bushing, which is difficult to distinguish with the naked eye. As a result, the right aluminum bracket is often mistaken for the left aluminum bracket and pressed in, causing the aluminum bracket to be scrapped.
A hydraulic bushing pressing device for aluminum brackets was designed. The device distinguishes between the left and right aluminum brackets by setting positioning components. It includes a worktable, an aluminum bracket mounting position, a bushing mounting position, and a press. Combined with positioning components, pressure cylinders, guide structures, and pressure sensors, it ensures that the bushing is accurately pressed into the corresponding aluminum bracket.
This technology enables reliable differentiation and correct pressing of the left and right aluminum brackets, avoiding mispressing of the aluminum brackets and improving production efficiency and product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of press-fitting equipment, specifically to a hydraulic bushing press-fitting equipment for aluminum brackets. Background Technology
[0002] To optimize vehicle handling, comfort, durability, and NVH performance, the vehicle's control arm is equipped with an aluminum bracket and a hydraulic bushing. The aluminum bracket serves as the mounting base for the control arm, while the hydraulic bushing is fixed between the subframe and the vibration source (such as the engine or suspension control arm), forming a controllable force transmission path.
[0003] Before installing the control arm into the aluminum bracket, the hydraulic bushing needs to be press-fitted into the aluminum bracket. There are two types of aluminum brackets, left and right, and they must be distinguished during the press-fitting of the hydraulic bushing. The mounting arms of the left and right aluminum brackets are offset to the left and right respectively relative to the axis of the hydraulic bushing, but this is difficult to distinguish visually. Therefore, in actual production, the right aluminum bracket may be manufactured as the left, resulting in incorrect pressing and rendering the aluminum bracket unusable. Utility Model Content
[0004] The purpose of this utility model is to provide an aluminum bracket hydraulic bushing pressing device, which distinguishes the left aluminum bracket and the right aluminum bracket by setting positioning elements.
[0005] To achieve the above objectives, this utility model provides an aluminum bracket hydraulic bushing pressing device, including a worktable, an aluminum bracket mounting position, a bushing mounting position, and a press. The aluminum bracket mounting position is fixedly set to the worktable, and the bushing mounting position is slidably connected to the aluminum bracket mounting position. The bracket mounting position is located below the bushing mounting position, and the aluminum bracket mounting position, the bushing mounting position, and the press are coaxially arranged.
[0006] The aluminum brackets are fitted with the aluminum bracket mounting positions, the bushings are fitted with the bushing mounting positions, and the lower end face of the press is provided with a pressure end. The pressure end is fitted with the upper end face of the bushing to push the bushing down into the aluminum bracket.
[0007] The hydraulic bushing pressing equipment for aluminum brackets also includes a positioning component, which is set facing the aluminum bracket installation position to distinguish between the left and right aluminum brackets.
[0008] Preferably, the bushing mounting position includes a first pin that mates with the bushing, a first support surface that supports the lower end face of the bushing, and a second pin located below the first support surface, the second pin mates with the aluminum bracket.
[0009] Preferably, the positioning element includes a left positioning element and a right positioning element, which cooperate with the left aluminum bracket and the right aluminum bracket, respectively.
[0010] Preferably, the positioning element is detachably connected to the worktable.
[0011] Preferably, the aluminum bracket hydraulic bushing pressing equipment also includes a pressure cylinder, which is fixedly connected to the worktable, and the telescopic rod of the pressure cylinder is fixedly connected to the bushing mounting position.
[0012] Preferably, a pressure sensor is installed at the connection point between the press and the pressure application end.
[0013] Preferably, the aluminum bracket hydraulic bushing pressing equipment further includes a guide structure, which is connected to the pressing end to guide the pressing end.
[0014] According to the above technical solution, the aluminum bracket of this utility model is sleeved on the aluminum bracket mounting position, and the bushing is sleeved on the bushing mounting position. The bushing mounting position is located above the aluminum bracket mounting position. When the press moves downward, the pressure end first acts on the upper end face of the bushing and pushes the bushing down together with the bushing mounting position until the bushing is pressed into the aluminum bracket, thereby realizing the pressing of the aluminum bracket and the bushing.
[0015] The aluminum bracket mounting position is fixedly set with the worktable, and the bushing mounting position is slidably connected with the aluminum bracket mounting position. When the press moves downward, it will push the bushing and the bushing mounting position downward together. During the downward movement of the press, the position of the aluminum bracket mounting position remains unchanged. Therefore, the bushing can be continuously pressed into the aluminum bracket by the pressure end.
[0016] The aluminum bracket mounting position is provided with a through hole, through which the bushing and bushing mounting position can enter the aluminum bracket mounting position.
[0017] The aluminum bracket includes two parallel mounting arms, which are offset relative to the bracket body. The mounting arm of the left aluminum bracket is offset to the left side of the bracket body, and the mounting arm of the right aluminum bracket is offset to the right side. The positioning element is designed to identify whether the mounting arm of the aluminum bracket is offset to the left or right, thereby distinguishing between the left and right aluminum brackets.

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0037] In this utility model, unless otherwise stated, directional words such as "below," "lower end face," "coaxial," "upper end face," "left," and "right" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.
[0038] See Figure 1-2 The aforementioned aluminum bracket hydraulic bushing pressing equipment includes a workbench 1, an aluminum bracket mounting position 2, a bushing mounting position 3, and a press 4. The aluminum bracket mounting position 2 is fixedly set to the workbench 1, and the bushing mounting position 3 is slidably connected to the aluminum bracket mounting position 2. The aluminum bracket mounting position 2 is located below the bushing mounting position 3, and the aluminum bracket mounting position 2, the bushing mounting position 3, and the press 4 are coaxially arranged.
[0039] Aluminum bracket 6 is fitted with aluminum bracket mounting position 2, bushing 10 is fitted with bushing mounting position 3, and press 4 has a pressure end 43 on its lower end face. The pressure end 43 is fitted with the upper end face of bushing 10 to push bushing 10 down into aluminum bracket 6.
[0040] The aluminum bracket hydraulic bushing pressing equipment also includes a positioning component 5, which is set facing the aluminum bracket mounting position 2 to distinguish between the left aluminum bracket and the right aluminum bracket.
[0041] Through the implementation of the above technical solution, the aluminum bracket 6 is fitted into the aluminum bracket mounting position 2, and the bushing 10 is fitted into the bushing mounting position 3. The bushing mounting position 3 is located above the aluminum bracket mounting position 2. When the press 4 moves downward, the pressure end 43 first acts on the upper end face of the bushing 10 and pushes the bushing 10 down together with the bushing mounting position 3 until the bushing 10 is pressed into the aluminum bracket 6, thereby realizing the pressing of the aluminum bracket 6 and the bushing 10.
[0042] The aluminum bracket mounting position 2 is fixedly set with the worktable 1, and the bushing mounting position 3 is slidably connected with the aluminum bracket mounting position 2. When the press 4 moves downward, it will push the bushing 10 and the bushing mounting position 3 to move downward together. During the downward movement of the press 4, the position of the aluminum bracket mounting position 2 remains unchanged. Therefore, the bushing 10 can be continuously pressed into the aluminum bracket 6 by the pressure end 43.
[0043] The aluminum bracket mounting position 2 is provided with a through hole, through which the bushing 10 and the bushing mounting position 3 can enter the aluminum bracket mounting position 2.
[0044] The aluminum bracket 6 includes two parallel mounting arms 61, which are offset relative to the body of the aluminum bracket 6. The mounting arm 61 of the left aluminum bracket is offset to the left side of the left aluminum bracket body, and the mounting arm of the right aluminum bracket 6 is offset to the right side of the right aluminum bracket body. The positioning element 5 is configured to identify whether the mounting arm 61 of the aluminum bracket 6 is offset to the left or to the right, thereby distinguishing between the left and right aluminum brackets 6.
[0045] In this embodiment, preferably, the bushing mounting position 3 includes a first pin 32 that mates with the bushing 10, a first support surface 31 that supports the lower end face of the bushing 10, and a second pin 33 located below the first support surface 31. The second pin 33 mates with the aluminum bracket 6.
[0046] The bushing mounting position 3 includes a first pin 32 for positioning the bushing 10 and a first support surface 31 for supporting the bushing 10. When the bushing 10 is fitted with the bushing mounting position 3, the mounting hole in the middle of the bushing 10 fits with the pin 31, and the bottom surface of the bushing 10 contacts the first support surface 31. The first pin 32 can ensure the coaxiality of the bushing 10 and the aluminum bracket 6, and the first support surface 31 can effectively support the bushing 10, ensuring the stability of the bushing 10 during the pressing process.
[0047] The bushing mounting position 3 also includes a second pin 33 located below the first support surface 31 for positioning the aluminum bracket 6. The aluminum bracket 6 is sleeved on the second pin 33, and the lower end face of the aluminum bracket 6 is supported by the second support surface 21 of the aluminum bracket mounting position 2. The aluminum bracket 6 is placed on the second support surface 21. Through the limiting effect of the second pin 33, the aluminum bracket 6 and the bushing 10 are coaxially arranged. Therefore, by setting the bushing mounting position 3, the coaxiality of the press with the aluminum bracket 6 and the bushing 10 can be guaranteed, thus ensuring the pressing quality.
[0048] When the press 4 moves downward, the pressure end 43 pushes the bushing mounting position 3 down, the first pin 32, the first support surface 31 and the second pin 33 move down synchronously and pass through the through hole in the middle of the aluminum bracket mounting position 2, so that the bushing 10 enters the aluminum bracket 6, realizing the press fitting of the bushing 10 and the aluminum bracket 6.
[0049] In this embodiment, preferably, the positioning element 5 includes a left positioning element 5 and a right positioning element 5, which respectively cooperate with the left aluminum bracket 6 and the right aluminum bracket 6.
[0050] The two mounting arms 61 are asymmetrical about the axial section of the aluminum bracket 6 body. The distance between one mounting arm 61 and the axial section is smaller than the distance between the other mounting arm 61 and the axial section. The distance between the left mounting arm 61 of the left aluminum bracket and the axial section is greater than the distance between the right mounting arm 61 of the left aluminum bracket and the axial section, and the distance between the right mounting arm 61 of the right aluminum bracket and the axial section is greater than the distance between the left mounting arm 61 of the right aluminum bracket and the axial section.
[0051] The width of the positioning element 5 is consistent with the gap between the two mounting arms 61. When the positioning element 5 is engaged with the aluminum bracket 6, the positioning element 5 can penetrate between the two mounting arms 61, and the two sides of the positioning element 51 abut against the two mounting arms 61 respectively.
[0052] By setting the axial sections of the left and right aluminum brackets to be the same, the distance from the left side of the positioning element 5, which mates with the left aluminum bracket, to this axial section is greater; similarly, the distance from the right side of the positioning element 5, which mates with the right aluminum bracket, is greater. Therefore, the left positioning element 5, which positions the left aluminum bracket, has a greater distance from its left side to the axial section. When the right aluminum bracket mates with this left positioning element 5, its position is restricted by the second pin 33. Consequently, after the right aluminum bracket is fitted onto the second pin 33, its left mounting arm 61 will interfere with the left side of the positioning element 5, preventing the right aluminum bracket from being inserted. Therefore, by setting the positioning element 5, the left and right aluminum brackets can be reliably distinguished.
[0053] By switching between the left positioning component 5 and the right positioning component 5, the left aluminum bracket and the right aluminum bracket can be limited. The left positioning component 5 can be used to produce the left aluminum bracket. Moreover, when the left aluminum bracket and the right aluminum bracket are confused, the left positioning component 5 can also reliably exclude the right aluminum bracket, thus preventing the right aluminum bracket from being mixed into the production process of the left aluminum bracket 5.
[0054] Preferably, the positioning elements 5 can be marked to distinguish between the left positioning element 5 and the right positioning element 5. In one embodiment, the left positioning element 5 is marked "left" and the right positioning element 5 is marked "right," which can serve as a reminder to the staff and avoid confusion during use.
[0055] In this embodiment, preferably, the positioning member 5 is detachably connected to the worktable 1.
[0056] Since the left positioning component 5 and the right positioning component 5 need to be used interchangeably, the positioning component 5 is set to be detachably connected to the worktable 1, which makes it easy to disassemble the positioning component 5.
[0057] In one embodiment, the positioning element 5 is fixedly connected to the worktable 1 via a support rod 7. The support rod 7 is fixedly mounted on the worktable 1, and the upper end of the support rod 7 is provided with a mounting hole. The positioning element 5 can be connected to the support rod 7 via a fixing bolt 71.
[0058] Left positioning component 5 is used for producing the left aluminum bracket, and right positioning component 5 is used for producing the right aluminum bracket. Both left and right positioning components 5 are detachably connected to the support rod 7 via mounting holes. When different aluminum brackets 6 need to be operated, only the corresponding positioning component 5 needs to be replaced.
[0059] In this embodiment, preferably, the aluminum bracket hydraulic bushing pressing equipment further includes a pressure cylinder 8, which is fixedly connected to the worktable 1, and the telescopic rod of the pressure cylinder 8 is fixedly connected to the bushing mounting position 3.
[0060] When the bushing mounting position 3 is pressed down, the pressure cylinder 8 can push the bushing mounting position 3 out, so that the bushing mounting position 3 is reset. After being reset, the bushing mounting position 3 needs to be higher than the aluminum bracket mounting position 2 so that the bushing 10 is positioned above the aluminum bracket 6 after it mates with the bushing mounting position 3.
[0061] When using the aluminum bracket hydraulic bushing pressing equipment, first place the aluminum bracket 6 on the aluminum bracket mounting position 2, and then place the bushing 10 on the bushing mounting position 3. Start the press 4 to press down, and the pressure end 43 cooperates with the upper end face of the bushing 10 to continuously push the bushing 10 downward until the bushing 10 is pressed into the aluminum bracket 6. When the bushing 10 is fully pressed in, the worker takes out the pressed aluminum bracket 6. At this time, the pressure cylinder 8 is activated to push the bushing mounting position 3 to reset.
[0062] Preferably, a sensor is set to detect whether an aluminum bracket 6 has been placed on the aluminum bracket mounting position 2. When the sensor detects that there is no aluminum bracket 6 on the aluminum bracket mounting position 2, it will control the pressure cylinder 8 to push out the bushing mounting position 3, thereby realizing the automatic reset of the bushing mounting position 3.
[0063] In this embodiment, preferably, a pressure sensor 9 is provided at the position where the press 4 is connected to the pressure application end 43.
[0064] Pressure sensor 9 can record the pressure curve during the process of pressing bushing 10 into aluminum bracket 6. After the pressing work is completed, the staff can judge whether the pressing process of bushing 10 is qualified based on the pressure curve.
[0065] In this embodiment, preferably, the aluminum bracket hydraulic bushing pressing equipment further includes a guide structure, which is connected to the pressing end 43 to guide the pressing end 43.
[0066] The guiding mechanism includes a guide sleeve 41 and a guide rod 42. The guide sleeve 41 is fixedly connected to the press 4. During the downward movement of the press 4, the guide sleeve 41 moves downward along the guide rod 42.
[0067] At least two sets of guiding mechanisms are provided. Multiple sets of guiding mechanisms restrict the movement direction of the press 4, thereby ensuring the coaxiality of the pressure end 43 with the aluminum bracket 6 and the bushing.
[0068] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0069] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0070] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
