[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] refer to Figure 1 As shown, an embodiment of this application provides a press-fitting fixture 100 for an open bushing 300. The press-fitting fixture 100 includes a press head 110, a reducing cylinder 120, and a guide assembly 130. The control member 200 includes a control arm and an open bushing 300. The press-fitting fixture 100 can be used to press the open bushing 300 into the bushing hole 210 of the control arm.
[0026] Among them, such as Figure 1 As shown, bushing holes 210 are provided at both ends of the control arm. The open bushing 300 includes an outer tube 310 and an inner tube 320, with the outer tube 310 located on the outer periphery of the inner tube 320.
[0027] Specifically, in combination Figure 2 and Figure 3As shown, one end of the pressure head 110 is provided with a first groove 111, which is used to embed one end of the open bushing 300. One end of the reducing cylinder 120 is positioned on the control component 200, and the opening of the reducing cylinder 120 corresponds to one side of the bushing hole 210 of the control component 200. The reducing cylinder 120 is provided with a first through hole 121, which is used to guide the open bushing 300 to shrink radially. The pressure head 110 is used to press the open bushing 300 under the action of external force. The first groove 111 of the pressure head 110 is used to position the open bushing 300 and prevent the open bushing 300 from slipping during the pressing process. The pressure head 110 can press the open bushing 300 into the reducing cylinder 120, so that the open bushing 300 can be radially contracted after passing through the reducing cylinder 120. After radial contraction, the open bushing 300 can be smoothly pressed into the bushing hole 210 of the control component 200, eliminating the pre-shrinking process of the open bushing 300, which can improve the assembly efficiency of the open bushing 300 and reduce the processing cost.
[0028] In this embodiment, the guide assembly 130 includes a guide seat 131 and a guide post 132. The guide seat 131 is provided with a limiting part 1311, a second groove 1312, and a second through hole 1313. The second through hole 1313 is disposed at the bottom of the second groove 1312. The limiting part 1311 is used to limit the side of the control member 200 away from the reduced diameter cylinder 120. The second groove 1312 is used to limit the opening bushing 300. The guide post 132 passes through the guide seat 131 and the reduced diameter cylinder 120 in sequence and is connected to the pressure head 110. The axis of the pressure head 110, the axis of the reduced diameter cylinder 120, and the axis of the guide seat 131 are collinear. Correspondingly, in During the press-fitting of the open bushing 300, the axis of the press head 110, the axis of the reduced diameter cylinder 120, and the axis of the guide seat 131 are collinear to form an axial position for the open bushing 300. The second through hole 1313 of the guide seat 131 cooperates with the guide post 132 to guide the open bushing 300, preventing the open bushing 300 from shifting or shaking during the press-fitting process. The limiting part 1311 can radially limit the control component 200. The second groove 1312 is used to position the open bushing 300, providing a certain assembly space for the press-fitting process of the open bushing 300, ensuring that the open bushing 300 can be press-fitted into the bushing hole 210 of the control component 200 relatively smoothly, thereby improving the press-fitting effect of the open bushing 300.
[0029] refer to Figure 1 and Figure 2As shown, the press-fitting fixture 100 for the open bushing 300 has a first direction X. For example, the first direction X is defined as the height direction of the press-fitting fixture 100 for the open bushing 300. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the parts in the press-fitting fixture 100 for the open bushing 300 and should not be construed as limiting this application.
[0030] In one embodiment, alternatively, referencing Figure 2 and Figure 4 As shown, the groove wall of the second groove 1312 is provided with a first limiting step 1314. The first limiting step 1314 divides the second groove 1312 into a first sub-groove and a second sub-groove. The first sub-groove is used to limit the outer tube 310 of the open bushing 300, and the second sub-groove is used to limit the inner tube 320 of the open bushing 300. The first limiting step 1314 is used to limit the pressing displacement of the open bushing 300, so that the open bushing 300 is just pressed into the bushing hole 210. The groove wall of the first sub-groove clamps and limits the outer tube 310 of the open bushing 300, ensuring that the outer tube 310 of the open bushing 300 is pressed into place during the assembly process. The groove wall of the second sub-groove clamps and limits the inner tube 320 of the open bushing 300, ensuring that the outer tube 310 of the open bushing 300 is pressed into place during the assembly process, which has a better technical effect.
[0031] In one embodiment, alternatively, referencing Figure 3 and Figure 6 As shown, the pressure head 110 is provided with a third through hole 113, which is located at the bottom of the first groove 111. The guide post 132 is inserted into the third through hole 113. Under the action of external force, the pressure head 110 presses the open bushing 300 into the reduced diameter cylinder 120. At the same time, the first groove 111 provides positioning for the open bushing 300, ensuring that the pressing path of the open bushing 300 is linear. The third through hole 113 cooperates with the guide post 132 to ensure that the pressure head 110 moves axially and avoids the pressure head 110 from deviating.
[0032] In summary, the press head 110 of the press-fitting fixture 100 is used to press the open bushing 300 under external force. The first groove 111 of the press head 110 facilitates the positioning of the open bushing 300 and prevents slippage of the open bushing 300 during the press-fitting process. The press head 110 can press the open bushing 300 into the reducing cylinder 120, so that the open bushing 300 can be radially contracted after passing through the reducing cylinder 120. After radial contraction, the open bushing 300 can be smoothly pressed into the bushing hole 210 of the control component 200, omitting the pre-contraction process of the open bushing 300. During the press-fitting process of the open bushing 300, the axis of the press head 110... The axis of the reduced diameter cylinder 120 and the axis of the guide seat 131 are collinear, forming an axial position for the open bushing 300. The second through hole 1313 of the guide seat 131 cooperates with the guide post 132 to guide the open bushing 300, preventing the open bushing 300 from shifting or shaking during the pressing process. The limiting part 1311 can radially limit the control component 200. The second groove 1312 is used to position the open bushing 300, providing a certain assembly space for the pressing process of the open bushing 300, ensuring that the open bushing 300 can be pressed into the bushing hole 210 of the control component 200 relatively smoothly, thereby improving the pressing effect of the open bushing 300.
[0033] refer to Figure 1 As shown, embodiments of this application provide another press-fitting fixture 100 for an open bushing 300, the press-fitting fixture 100 including a press head 110, a reducing cylinder 120, and a guide assembly 130. The control member 200 includes a control arm and an open bushing 300, and the press-fitting fixture 100 can be used to press the open bushing 300 into the bushing hole 210 of the control arm.
[0034] Among them, such as Figure 1 As shown, bushing holes 210 are provided at both ends of the control arm. The open bushing 300 includes an outer tube 310 and an inner tube 320, with the outer tube 310 located on the outer periphery of the inner tube 320.
[0035] Specifically, in combination Figure 2 and Figure 3As shown, one end of the pressure head 110 is provided with a first groove 111, which is used to embed one end of the open bushing 300. One end of the reducing cylinder 120 is positioned on the control component 200, and the opening of the reducing cylinder 120 corresponds to one side of the bushing hole 210 of the control component 200. The reducing cylinder 120 is provided with a first through hole 121, which is used to guide the open bushing 300 to shrink radially. The pressure head 110 is used to press the open bushing 300 under the action of external force. The first groove 111 of the pressure head 110 is used to position the open bushing 300 and prevent the open bushing 300 from slipping during the pressing process. The pressure head 110 can press the open bushing 300 into the reducing cylinder 120, so that the open bushing 300 can be radially contracted after passing through the reducing cylinder 120. After radial contraction, the open bushing 300 can be smoothly pressed into the bushing hole 210 of the control component 200, eliminating the pre-shrinking process of the open bushing 300, which can improve the assembly efficiency of the open bushing 300 and reduce the processing cost. The guide assembly 130 includes a guide seat 131 and a guide post 132. The guide seat 131 is provided with a limiting part 1311, a second groove 1312, and a second through hole 1313. The second through hole 1313 is located at the bottom of the second groove 1312. The limiting part 1311 is used to limit the control member 200 on the side away from the reduced diameter cylinder 120. The second groove 1312 is used to limit the opening bushing 300. The guide post 132 passes through the guide seat 131 and the reduced diameter cylinder 120 in sequence and is connected to the pressure head 110. The axis of the pressure head 110, the axis of the reduced diameter cylinder 120, and the axis of the guide seat 131 are collinear. Correspondingly, in the opening bushing... During the press-fitting process of the bushing 300, the axis of the press head 110, the axis of the reduced diameter cylinder 120, and the axis of the guide seat 131 are collinear to form an axial position for the open bushing 300. The second through hole 1313 of the guide seat 131 cooperates with the guide post 132 to guide the open bushing 300, preventing the open bushing 300 from shifting or shaking during the press-fitting process. The limiting part 1311 can radially limit the control component 200. The second groove 1312 is used to position the open bushing 300, providing a certain assembly space for the press-fitting process of the open bushing 300, ensuring that the open bushing 300 can be press-fitted into the bushing hole 210 of the control component 200 relatively smoothly, thereby improving the press-fitting effect of the open bushing 300.
[0036] In one embodiment, alternatively, referencing Figure 2 and Figure 4As shown, the groove wall of the second groove 1312 is provided with a first limiting step 1314. The first limiting step 1314 divides the second groove 1312 into a first sub-groove and a second sub-groove. The first sub-groove is used to limit the outer tube 310 of the open bushing 300, and the second sub-groove is used to limit the inner tube 320 of the open bushing 300. The first limiting step 1314 is used to limit the pressing displacement of the open bushing 300, so that the open bushing 300 is just pressed into the bushing hole 210. The groove wall of the first sub-groove clamps and limits the outer tube 310 of the open bushing 300, ensuring that the outer tube 310 of the open bushing 300 is pressed into place during the assembly process. The groove wall of the second sub-groove clamps and limits the inner tube 320 of the open bushing 300, ensuring that the outer tube 310 of the open bushing 300 is pressed into place during the assembly process.
[0037] Furthermore, combined Figure 3 and Figure 4 As shown, the limiting part 1311 is disposed at one end of the guide seat 131 near the second groove 1312. The limiting part 1311 and the groove opening of the second groove 1312 define a second limiting step 1315. The second limiting step 1315 is used to limit one side of the bushing hole 210 of the control member 200. The limiting part 1311 and the groove opening of the second groove 1312 form the second limiting step 1315. The second limiting step 1315 can keep the control member 200 relatively positioned during the pressing process and avoid the control member 200 from shifting during the pressing process.
[0038] Optionally, refer to Figure 2 As shown, the press-fitting fixture 100 also includes a gasket 140, which is disposed within the second groove 1312 and sleeved on the guide post 132. The gasket 140 can be used to adjust the depth of the second groove 1312, so as to adjust the press-fitting depth by placing the gasket 140 at the assembly position of the open bushing 300. The gasket 140 allows for different exposed portions of the open bushing 300 at the bushing hole 210 position. For example, the gasket 140 has a circular ring structure.
[0039] For example, such as Figure 4 As shown, the limiting part 1311 has a semi-circular structure and is used for the lateral movement of the radial limiting control member 200.
[0040] One end of the reduced diameter cylinder 120 is positioned on the control component 200, so that the opening of the reduced diameter cylinder 120 corresponds to the bushing hole 210, ensuring that the open bushing 300 is pressed into the bushing hole 210 more accurately.
[0041] In one embodiment, alternatively, referencing Figure 2 and Figure 5As shown, the first through hole 121 is provided with a first hole wall 1211, a second hole wall 1212 and a third hole wall 1213. The second hole wall 1212 is located between the first hole wall 1211 and the third hole wall 1213. The diameter of the third hole wall 1213 is smaller than the diameter of the first hole wall 1211. The first through hole 121 can be used to guide the radial contraction of the opening bushing 300, so that the opening bushing 300 passes through the first hole wall 1211, the second hole wall 1212 and the third hole wall 1213 in sequence, thereby achieving the purpose of radial contraction of the opening bushing 300.
[0042] Furthermore, such as Figure 5 As shown, both the first hole wall 1211 and the third hole wall 1213 are of equal diameter. From the first hole wall 1211 to the third hole wall 1213, the diameter of the second hole wall 1212 gradually decreases. Near the third hole wall 1213, the diameter of the second hole wall 1212 is equal to that of the third hole wall 1213. Near the first hole wall 1211, the diameter of the second hole wall 1212 is equal to that of the third hole wall 1213. The equal diameter structure of the first hole wall 1211 and the third hole wall 1213 can provide stable guidance. The gradually decreasing diameter of the second hole wall 1212 forms a tapered transition section, which allows the open bushing 300 to shrink smoothly, reducing the diameter reduction process of the open bushing 300 during the press-fitting process.
[0043] In one embodiment, alternatively, referencing Figure 3 and Figure 6 As shown, the pressure head 110 is provided with a third through hole 113, which is located at the bottom of the first groove 111. The guide post 132 is inserted into the third through hole 113. Under the action of external force, the pressure head 110 presses the open bushing 300 into the reduced diameter cylinder 120. At the same time, the first groove 111 provides positioning for the open bushing 300, ensuring that the pressing path of the open bushing 300 is linear. The third through hole 113 cooperates with the guide post 132 to ensure that the pressure head 110 moves axially and avoids the pressure head 110 from deviating.
[0044] For example, the pressure head 110 has a cylindrical structure, and the pressure head 110 is aligned with the open bushing 300 during positioning.
[0045] Furthermore, such as Figure 6As shown, a boss 112 is provided at the groove opening of the first groove 111. The boss 112 is used to engage with the limiting edge 330 of the opening bushing 300, so that the boss 112 and the limiting edge 330 of the opening bushing 300 are engaged. The boss 112 of the first groove 111 prevents the opening bushing 300 from moving radially during the pressing process. The boss 112 is embedded in the gap between the outer tube 310 and the inner tube 320 of the opening bushing 300, ensuring that the opening bushing 300 is aligned and pressed into the bushing hole 210.
[0046] In one embodiment, this application discloses a pressing method, the pressing method comprising the following steps: S100: Insert the guide post 132 into the guide base; S200: Place the control component 200 on the guide seat 131, so that the control component 200 is positioned in the limiting part 1311 of the guide seat 131, place the reducing cylinder 120 on the side of the control component 200 away from the guide seat 131 and the cylinder opening of the reducing cylinder 120 corresponds to the bushing hole 210 of the control component 200, so that the third hole wall 1213 of the reducing cylinder 120 is located close to the control component 200. S300: Place the open bushing 300 into the reducing cylinder 120, and make both the open bushing 300 and the reducing cylinder 120 fit on the guide post 132. S400: Install the pressure head 110 at the end of the open bushing 300 away from the reducer 120, start the press to press the pressure head 110 until the open bushing 300 is assembled in place. S500: Remove the pressure head 110 and the reducing cylinder 120 to complete the press-fitting on one side; S600: Flip the control component 200 and repeat the above steps to complete the pressing of the other end of the control component 200.
[0047] Embodiments of the present invention also provide a press-fitting system, including the press-fitting fixture 100 described in any of the above embodiments.
