[0002] With the development of science and technology, vehicles, as an important part of modern transportation, play an increasingly vital role in people's daily lives. During vehicle production, bushings are typically pressed into the vehicle body crossbeams to provide cushioning, positioning, and noise reduction. However, traditional pressing devices cannot simultaneously meet the crossbeam pressing requirements of various vehicle models, resulting in poor versatility.
[0003] Therefore, it is necessary to provide a new pressing device and bushing pressing equipment to solve the above-mentioned technical problems. Utility Model Content
[0004] The main purpose of this utility model is to provide a pressing device and bushing pressing equipment, which aims to solve the technical problem of poor versatility of the pressing device.
[0005] To achieve the above objectives, this utility model proposes a pressing device, comprising:

[0008] The second pressing assembly is disposed below the first pressing assembly. The second pressing assembly includes a base, a driving member, and a first pressing head and a second pressing head spaced apart from the base. The base is slidably disposed on the frame. The driving member can drive the base to slide, thereby driving the first pressing head and the second pressing head to slide.
[0009] When the upper pressure head is in the first pressing state, the driving member drives the first lower pressure head to slide directly below the upper pressure head; when the upper pressure head is in the second pressing state, the driving member drives the second lower pressure head to slide directly below the upper pressure head.
[0010] In one embodiment, the upper pressure head includes a pressure head body and an insert. The pressure head body is provided with a first receiving hole for the first lower pressure head to be inserted, and the insert is provided with a second receiving hole for the second lower pressure head to be inserted. The first receiving hole and the second receiving hole both extend along the line connecting the first pressing assembly and the second pressing assembly. The insert is slidably disposed in the first receiving hole along the central axis of the pressure head body.
[0011] When the upper pressure head is in the first pressing state, the insert slides to one end of the first receiving hole near the second pressing component; when the upper pressure head is in the second pressing state, the insert slides to one end of the first receiving hole away from the second pressing component.
[0012] In one embodiment, the insert is provided with a guide rod, the pressure head body is provided with a guide hole, and the guide rod passes through the guide hole.
[0013] In one embodiment, the first pressing assembly further includes a locking member for locking the insert at one end of the first receiving hole near the second pressing assembly and for releasing the position lock of the insert.
[0014] In one embodiment, the locking element includes a drive cylinder and an insert block. The drive cylinder is disposed on the frame, and the insert block is disposed on the drive cylinder. The drive cylinder can drive the insert block to move and insert into the end of the first receiving hole away from the second pressing component, so as to lock the insert block in the end of the first receiving hole near the second pressing component. The drive cylinder can also drive the insert block to slide away from the first receiving hole, so as to release the position lock of the insert block.
[0015] In one embodiment, the insert block is provided with two insert rods, which are spaced apart along the radial direction of the pressure head body. The pressure head body is provided with two clearance holes, and the two insert rods are provided in a one-to-one correspondence with the two clearance holes. The driving member can drive the insert block to move, thereby driving the corresponding insert rod to pass through the corresponding clearance hole and insert into the end of the first receiving hole away from the second pressing component.
[0016] In one embodiment, the pressing device further includes a driving assembly disposed on the frame, the base being slidably disposed on the driving assembly, and the driving assembly being used to drive the second pressing assembly to slide along the height direction of the frame.
[0017] In one embodiment, the drive assembly includes a mounting base and a drive unit. The mounting base is slidably disposed on the frame along the height direction of the frame. The drive unit drives the mounting base to slide along the height direction of the frame via a lead screw. The base is slidably disposed on the mounting base.
[0018] In one embodiment, the base is provided with a slider, the mounting base is provided with a slide rail, and the slider is slidably disposed on the slide rail.
[0019] In addition, this utility model also proposes a bushing pressing device, comprising:
[0020] A frame, wherein a processing area is provided on one side of the frame, and a slide is provided on the frame;
[0021] The pressing device described above is slidably disposed on the slide block;
[0022] A drive body is disposed on the frame and is capable of driving the pressing device to slide, so that the pressing device slides into or away from the processing area.
[0023] The technical solution of this utility model, by setting an upper pressing head with a first pressing state and a second pressing state, and setting a first pressing head and a second pressing head that can be switched by a driving component, enables the pressing device to complete the pressing of bushings for various vehicle models, thus improving the versatility of the pressing device. In this embodiment, the upper pressing head has a switchable first pressing state and a second pressing state, which can meet the bushing pressing requirements of different vehicle models. The second pressing assembly includes a base slidably disposed on the frame, a first pressing head and a second pressing head spaced apart from the base, and a driving component that drives the base to slide. The driving component can drive the base to slide, thereby driving the first pressing head and the second pressing head to switch positions to meet the bushing pressing requirements of different vehicle models. Specifically, when pressing a bushing of a certain vehicle model into the crossbeam, the upper pressure head switches to the first pressing state, the driving component drives the base to slide, and then drives the first lower pressure head to slide directly below the upper pressure head. At this time, the first lower pressure head can cooperate with the upper pressure head to complete the pressing of the bushing of that vehicle model. When pressing a bushing of another vehicle model into the crossbeam, the upper pressure head switches to the second pressing state, the driving component drives the base to slide, and then drives the second lower pressure head to slide directly below the upper pressure head. At this time, the second lower pressure head can cooperate with the upper pressure head to complete the pressing of the bushing of another vehicle model. This pressing device, by setting an upper pressure head with first and second pressing states, and setting a first and second lower pressure head that can be switched in position, can enable the pressing device to press bushings of multiple different vehicle models, improving the versatility of the pressing device. Furthermore, using a single pressing device to press bushings of multiple different vehicle models can reduce the number of parts to be purchased later, thereby reducing the vehicle manufacturing cost.

[0036] Bushings, as important components installed on the vehicle body crossbeams, play a role in buffering, positioning, and noise reduction. Most bushings are pressed into the crossbeams using a press-in device. In actual production, researchers have found that traditional press-in devices can only press bushings into the crossbeams of a single vehicle model, and cannot press bushings into the crossbeams of multiple different vehicles, resulting in a technical problem of poor versatility.
[0037] This utility model proposes a pressing device and a bushing pressing equipment, aiming to solve the technical problem of poor versatility of the pressing device.
[0038] Please see Figures 1 to 4 In one embodiment of this utility model, the pressing device is used to press the bushing into the crossbeam. The pressing device includes a frame 100, a first pressing component 200, and a second pressing component 300. The first pressing component 200 is disposed on the frame 100 and includes an upper pressing head 210, which has a first pressing state and a second pressing state. The second pressing component 300 is disposed below the first pressing component 200 and includes a base 310, a driving member 320, and components spaced apart from each other on the base. The first pressing head 330 and the second pressing head 340 of the upper pressing head 210 are slidably disposed on the frame 100. The driving member 320 can drive the base 310 to slide, thereby driving the first pressing head 330 and the second pressing head 340 to slide. When the upper pressing head 210 is in the first pressing state, the driving member 320 drives the first pressing head 330 to slide directly below the upper pressing head 210. When the upper pressing head 210 is in the second pressing state, the driving member 320 drives the second pressing head 340 to slide directly below the upper pressing head 210. The driving member 320 can be a driving cylinder or a driving hydraulic cylinder.
[0039] The technical solution of this utility model, by setting an upper pressing head 210 with a first pressing state and a second pressing state, and setting a first lower pressing head 330 and a second lower pressing head 340 that can be switched by a driving member 320, enables the pressing device to complete the pressing of bushings for various vehicle models, thereby improving the versatility of the pressing device. In this embodiment, the upper pressing head 210 has a switchable first pressing state and a second pressing state to meet the bushing pressing requirements of different vehicle models. The second pressing assembly 300 includes a base 310 slidably disposed on the frame 100, a first lower pressing head 330 and a second lower pressing head 340 spaced apart from the base 310, and a driving member 320 that drives the base 310 to slide. The driving member 320 can drive the base 310 to slide, thereby driving the first lower pressing head 330 and the second lower pressing head 340 to switch positions to meet the bushing pressing requirements of different vehicle models. Specifically, when pressing a bushing of a certain vehicle model into the crossbeam, the upper pressure head 210 switches to the first pressing state, the driving component 320 drives the base 310 to slide, and then drives the first lower pressure head 330 to slide directly below the upper pressure head 210. At this time, the first lower pressure head 330 can cooperate with the upper pressure head 210 to complete the pressing of the bushing of a certain vehicle model. When pressing a bushing of another vehicle model into the crossbeam, the upper pressure head 210 switches to the second pressing state, the driving component 320 drives the base 310 to slide, and then drives the second lower pressure head 340 to slide directly below the upper pressure head 210. At this time, the second lower pressure head 340 can cooperate with the upper pressure head 210 to complete the pressing of the bushing of another vehicle model. This press-fit device, by providing an upper press head 210 with a first pressing state and a second pressing state, and a first lower press head 330 and a second lower press head 340 that can be switched in position, enables the press-fit device to perform bushing press-fitting for various vehicle models, thus improving the versatility of the press-fit device. Furthermore, using a single press-fit device to perform bushing press-fitting for multiple vehicle models reduces the number of subsequent parts to be procured, thereby lowering vehicle manufacturing costs.
[0040] It should be noted that, in the actual manufacturing of this pressing device, the pressing state of the upper pressing head 210 can be designed to be three, four, five, etc., and the number of the lower pressing heads can also be designed to be three, four, five, etc., to meet the bushing pressing requirements of more different vehicle models.
[0041] Please see Figure 3 and Figure 4In one embodiment of this utility model, the upper pressure head 210 includes a pressure head body 211 and an insert 212. The pressure head body 211 is provided with a first receiving hole 2111 for the insertion of a first lower pressure head 330, and the insert 212 is provided with a second receiving hole 2121 for the insertion of a second lower pressure head 340. Both the first receiving hole 2111 and the second receiving hole 2121 extend along the line connecting the first pressing assembly 200 and the second pressing assembly 300. The insert 212 is slidably disposed in the first receiving hole 2111 along the central axis of the pressure head body 211. In this embodiment, the first receiving hole 2111 of the pressure head body 211 is used to cooperate with the first lower pressure head 330 to complete the pressing of a bushing for a certain vehicle model; the second receiving hole 2121 of the insert 212 is used to cooperate with the second lower pressure head 340 to complete the pressing of a bushing for another vehicle model. By slidably positioning the insert 212 within the first receiving hole 2111 of the pressing body, the pressing state of the upper pressing head 210 can be switched, simplifying the structure of the upper pressing head 210 and reducing its manufacturing difficulty. Specifically, when the upper pressing head 210 is in the first pressing state, the insert 212 slides to the end of the first receiving hole 2111 near the second pressing component 300, and the end face of the insert 212 facing the second pressing component 300 is flush with the end face of the pressing head body 211 facing the second pressing component 300; when the upper pressing head 210 is in the second pressing state, the insert 212 slides to the end of the first receiving hole 2111 away from the second pressing component 300.
[0042] It should be noted that when pressing bushings of different vehicle models into the crossbeam, the corresponding lower pressing head needs to be inserted into the corresponding receiving hole. Specifically, the bushing pressing process for a certain vehicle model is as follows: First, slide the insert 212 to one end of the first receiving hole 2111 near the second pressing assembly 300, and use the locking member 220 to lock the position of the insert 212, so that the upper pressing head 210 is in the first pressing state; then the driving member 320 drives the first lower pressing head 330 to slide directly below the upper pressing head 210; the driving assembly 400 drives the second pressing assembly 300 and the crossbeam placed on the second pressing assembly 300 to rise, and then the first lower pressing head 330 will pass through the bushing hole of the crossbeam and be inserted into the second receiving hole 2121, completing the bushing pressing of a certain vehicle model. The bushing pressing process for another model is as follows: First, the locking member 220 is used to unlock the position lock of the insert 212, so that the upper pressing head 210 can switch to the second pressing state; then the driving member 320 drives the second lower pressing head 340 to slide directly below the upper pressing head 210, and the driving assembly 400 drives the second pressing assembly 300 and the crossbeam placed on the second pressing assembly 300 to rise. Then the second lower pressing head 340 will pass through the bushing hole of the crossbeam, push the insert 212 to move towards the end of the first receiving hole 2111 away from the second pressing assembly 300 and insert it into the first receiving hole 2111, thus completing the bushing pressing of the other model.
[0043] Please see Figures 2 to 4 In one embodiment of this utility model, the insert 212 is provided with a guide rod 2122, and the pressure head body 211 is provided with a guide hole 2112, with the guide rod 2122 passing through the guide hole 2112. In this embodiment, by passing the guide rod 2122 through the guide hole 2112, the sliding of the insert 212 can be guided, ensuring that the upper pressure head 210 can accurately switch between various pressing states.
[0044] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the first pressing assembly 200 further includes a locking member 220. The locking member 220 is used to lock the insert 212 at one end of the first receiving hole 2111 near the second pressing assembly 300, and to release the position lock of the insert 212. In this embodiment, the locking member 220 can lock the insert 212 at one end of the first receiving hole 2111 near the second pressing assembly 300 when pressing in a bushing of a certain vehicle model, that is, lock the upper pressing head 210 in the first pressing state; and can unlock the position lock of the insert 212 when pressing in a bushing of another vehicle model.

The drive cylinder 221 is disposed on the frame 100, and the insert block 222 is disposed on the drive cylinder 221. The drive cylinder 221 can drive the insert block 222 to move and insert into the end of the first receiving hole 2111 away from the second pressing component 300, so as to lock the insert block 212 in the end of the first receiving hole 2111 near the second pressing component 300, thereby locking the upper pressing head 210 in the first pressing state. The drive cylinder 221 can also drive the insert block 222 to slide away from the first receiving hole 2111, releasing the position lock of the insert block 212, so that the upper pressing head 210 can switch to the second pressing state. In a specific embodiment, the drive cylinder 221 can be a drive cylinder or a drive hydraulic cylinder.
[0046] Please see Figure 2In one embodiment of this utility model, the insert block 222 is provided with two insert rods 2221, which are spaced apart along the radial direction of the pressure head body 211. The pressure head body 211 is provided with two clearance holes 2113, and the two insert rods 2221 are correspondingly arranged with the two clearance holes 2113. The driving member 320 can drive the insert block 222 to move, thereby driving the corresponding insert rod 2221 to pass through the corresponding clearance hole 2113 and insert into the end of the first receiving hole 2111 away from the second pressing component 300. In this embodiment, the two insert rods 2221 spaced apart from the insert block 222 can be simultaneously inserted into the end of the first receiving hole 2111 away from the second pressing component 300, locking the insert block 212 in the end of the first receiving hole 2111 near the second pressing component 300, thereby locking the upper pressure head 210 in the first pressing state.
