Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to a closing mechanism for pressing an open bushing. Background Technique

[0002] At present, when installing an open bushing, generally, the open bushing is directly placed in a tapered sleeve, and then a tool is used to squeeze the open bushing so that it passes through the inside of the tapered sleeve, and the open bushing can be shrunk.

[0003] However, this direct extrusion installation method for the open bushing cannot support the inner wall of the open bushing. Therefore, when the open bushing abuts against the inner wall of the tapered sleeve, all the acting forces during the abutting process will act on one end of the open bushing, which is likely to cause different deformations at the stressed end and the non-stressed end of the opening, and thus it is easy to cause the open bushing to be distorted.

[0004] Therefore, it is necessary to provide a new closing mechanism for pressing an open bushing to solve the above technical problems. Content of the Utility Model

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0029] Please refer to Figures 1 to 6 , a closing mechanism for press-fitting an opening bushing provided by an embodiment of the present utility model, the closing mechanism for press-fitting an opening bushing includes: a mounting bracket 1.

[0030] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 . A support cylinder 2 is provided at the center of the top of the mounting frame 1. The top end of the support cylinder 2 is provided with a support frame 21, and an auxiliary component 3 is provided on the support frame 21. The auxiliary component 3 includes a driving motor 31 and a support bar 32. The driving motor 31 is arranged inside the support frame 21. The output end of the driving motor 31 is provided with a driving rod 311. A driving block 312 connected by threads is sleeved outside the driving rod 311. A plurality of support bars 32 are provided and are annularly distributed on the top of the support frame 21. An inner arc-shaped piece 33 is provided outside the support bar 32 through a telescopic rod 332. A sliding frame 341 connected by sliding is inserted inside the inner arc-shaped piece 33. A second spring 342 is arranged between the sliding frame 341 and the inner arc-shaped piece 33. And an outer arc-shaped piece 34 is provided at one end of the sliding frame 341 away from the inner driving rod 311. A first spring 333 is sleeved outside the telescopic rod 332. And both ends of the first spring 333 are fixedly connected to the support bar 32 and the inner arc-shaped piece 33 respectively. Inclined blocks 331 are provided on the inner walls of the inner arc-shaped pieces 33. The outer walls of the inclined blocks 331 are abutted against and slidably connected to the outer wall of the driving block 312. And the outer walls of the inclined blocks 331 and the driving block 312 are both of slope structures.

[0031] It should be noted that: the outer arc-shaped piece 34 is erected through the sliding frame 341. During use, after the opening bushing is sleeved outside the outer arc-shaped piece 34, when the tapered bushing 421 squeezes and contracts the opening bushing, the outer arc-shaped piece 34 located inside the opening bushing can support the inner wall of the opening bushing through the support of the sliding frame 341 and the second spring 342. Furthermore, when the inner wall of the opening bushing is squeezed by the tapered bushing 421, the force is more uniform, avoiding the phenomenon of twisting and deformation due to uneven force. Therefore, the later installation effect of the opening bushing can be improved;

[0032] It should also be noted that: after the opening bushing is inserted into the steering knuckle shaft hole, the driving motor 31 can be controlled to drive the driving rod 311 to rotate. The rotating driving rod 311 can drive the driving block 312 to slide downward on the outer wall of the support bar 32 through a threaded structure, reducing the extrusion between the driving block 312 and the inclined block 331. At this time, the first spring 333 can pull the inner arc-shaped piece 33, so that a plurality of inner arc-shaped pieces 33 move towards the center of the opening bushing. Furthermore, the extrusion force between the outer arc-shaped piece 34 and the bushing can be reduced. Then, when the support cylinder 2 is controlled to retract, the outer arc-shaped piece 34 can slide out of the opening bushing more smoothly;

[0033] At the same time, the outer wall specification of the support frame 21 is larger than the specification of the circular structure formed by a plurality of outer arc-shaped pieces 34 in the initial state. Therefore, when the opening bushing is sleeved outside the outer arc-shaped piece 34, the top of the support frame 21 can support the bottom of the opening bushing, enabling it to be stably inserted and installed into the shaft hole of the steering knuckle.

[0034] In an embodiment of the present utility model, please refer to Figure 1 and Figure 5 , above the top support frame 21 of the mounting frame 1, a contraction assembly 4 is provided. The contraction assembly 4 includes a support piece 41, and a tapered sleeve 421 is arranged inside the support piece 41. One side of the bottom of the support piece 41 is provided with a driving cylinder 411, and the bottom end of the driving cylinder 411 is connected to the mounting frame 1. The other side inside the support piece 41 is inserted with a guide rod 412, and the bottom end of the guide rod 412 is connected to the mounting frame 1. The center inside the support piece 41 is provided with a mounting ring 42 through bolts, and the inner wall of the mounting ring 42 is fixedly connected to the outer wall of the tapered sleeve 421.

[0035] It should be noted that: by connecting the bolt tapered sleeve 421 and the support piece 41, during later use, the specification of the tapered sleeve 421 can be flexibly replaced and adjusted according to the required specification of the opening bushing to be installed, so that the device can install opening bushings of various specifications, improving the applicable range of the device;

[0036] It should also be noted that: the inner wall specifications of various specifications of tapered sleeves 421 are all larger than the outer wall specification of the support frame 21. Therefore, during the installation of the opening bushing later, the support frame 21 can drive the auxiliary assembly 3 and the opening bushing at the top to penetrate through the inner wall of the tapered sleeve 421, thus avoiding the support frame 21 from abutting against the inner wall of the tapered sleeve 421 and causing an obstacle to the later installation and insertion of the opening bushing;

[0037] And through the setting of the driving cylinder 411, during the extrusion installation process of the opening bushing, by the contraction of the driving cylinder 411, the bushing can be driven to move downward through the support piece 41, so that the contracted opening bushing can penetrate through the tapered sleeve 421 and be inserted into the shaft hole of the steering knuckle for installation. During the movement of the support piece 41 along with the driving cylinder 411, the guide rod 412 can guide the movement track of the support piece 41, which can not only improve the stability of the later movement of the support piece 41, but also increase the horizontal support strength of the driving cylinder 411 later.

[0038] In an embodiment of the present utility model, please refer to Figure 1 and Figure 4, a pressing component 5 is installed on the mounting bracket 1. The pressing component 5 includes a fixing bracket 51 which is arranged on the mounting bracket 1. A screw rod 52 with a rotational connection is arranged on one side of the fixing bracket 51 close to the supporting cylinder 2. A connecting strip 522 connected by threads is sleeved outside the screw rod 52. A supporting cylinder 53 is arranged at the bottom end of the connecting strip 522. A connecting column 531 connected by threads is arranged inside the supporting cylinder 53, and a pressing piece 532 is arranged at the bottom end of the connecting column 531. A sliding groove 511 is formed below the screw rod 52 inside the fixing bracket 51. The inner wall of the sliding groove 511 abuts against and is slidably connected to the outer wall of the connecting strip 522. One end of the screw rod 52 penetrates through the fixing bracket 51 and is provided with a rotating motor 521, and the rotating motor 521 is connected to the fixing bracket 51.

[0039] It should be noted that during use, the rotating motor 521 can be controlled to drive the screw rod 52 to rotate. At this time, the rotating screw rod 52 can drive the connecting strip 522 and its components to slide inside the sliding groove 511 through the threaded structure. The sliding connecting strip 522 can drive the pressing piece 532 at the bottom end to move. Thus, when installing the steering knuckle later, the position of the pressing piece 532 can be flexibly adjusted according to whether the steering knuckle to be installed is a left steering knuckle or a right steering knuckle.

[0040] After the position of the pressing piece 532 is adjusted, the connecting column 531 can be controlled to rotate inside the supporting cylinder 53 to drive the pressing piece 532 to move in the vertical direction. Thus, the pressing piece 532 can smoothly abut against the top of the steering knuckle. Therefore, when installing the opening bushing later, the stability of the steering knuckle can be improved, and the phenomenon that the fork of the steering knuckle for installing the bushing appears prestressed bending can be reduced. Therefore, the stability of the fork of the steering knuckle during the installation process can be improved.

[0041] In the embodiment of the present utility model, please refer to Figure 1 and Figure 6 , a controller 11 is arranged on one side of the top of the mounting bracket 1, and three-jaw chucks 12 symmetrically distributed are arranged on the other side of the top of the mounting bracket 1.

[0042] It should be noted that through the setting of the three-jaw chucks 12, when installing the opening bushing of the steering knuckle, the steering knuckle can be clamped and fixed by the three-jaw chucks 12, which is convenient for the subsequent installation of the opening bushing.

[0043] The working principle of the closing mechanism for pressing the opening bushing provided by the present utility model is as follows:

[0044] When using this closing mechanism, the staff can first place the steering knuckle that needs to install the bushing on the three-jaw chuck on the corresponding side for fixation. Then, the screw rod 52 can be controlled to rotate to drive the pressing piece 532 below to move, so that the pressing piece 532 moves to the corresponding part of the steering knuckle. Then, the connecting column 531 can be controlled to rotate to drive the pressing piece 532 to move downward until the bottom of the pressing piece 532 abuts against the top of the knuckle fork of the steering knuckle, and the fixation of the steering knuckle can be completed.

[0045] Then, the required split bushing can be taken out and sleeved on the outer arc-shaped piece 34. Then, the support cylinder 2 can be controlled to work to drive the auxiliary component 3 and the split bushing to move upward, so that the split bushing moves in the direction of the tapered sleeve 421. When the outer wall of the split bushing abuts against the inner wall of the tapered sleeve 421, the split bushing can be contracted by the extrusion of the inner wall of the tapered sleeve 421 on the split bushing.

[0046] At this time, the contracted split bushing can extrude the inner outer arc-shaped piece 34. When the outer arc-shaped piece 34 is subjected to the extrusion force of the split bushing, it can move toward the center of the split bushing through the sliding frame 341 in the inner arc-shaped piece 33. By the support of the outer arc-shaped piece 34 on the inner wall and the port of the split bushing, it can be avoided that when the split bushing is squeezed and contracted by the tapered sleeve 421, the end part shrinks excessively, resulting in the phenomenon that the split bushing is distorted. Furthermore, the contraction of the split bushing can be more uniform and stable.

[0047] With the continuous movement of the support cylinder 2, when the split bushing penetrates from the inside of the tapered sleeve 421 and moves into the shaft hole where the steering knuckle needs to be installed, the driving motor 31 can be controlled to rotate. At this time, the rotating driving motor 31 can drive the driving rod 311 to rotate. The rotating driving rod 311 can drive the driving block 312 to slide downward on the outer wall of the support bar 32 through the threaded structure, and the extrusion between the driving block 312 and the inclined block 331 can be reduced. At this time, the first spring 333 can pull the inner arc-shaped piece 33, so that several inner arc-shaped pieces 33 move toward the center of the split bushing. Furthermore, the extrusion force between the outer arc-shaped piece 34 and the bushing can be reduced. Furthermore, when the support cylinder 2 is controlled to retract, the outer arc-shaped piece 34 can slide out of the split bushing more smoothly. Thus, the use of this device can be completed.

[0048] The circuits and controls involved in this utility model are all prior arts and will not be elaborated here.

[0049] The above are only the embodiments of this utility model, and do not limit the patent scope of this utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of this utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of this utility model.
