Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, specifically to an automated press-fit tooling for automotive parts. Background Technology

[0002] In the field of automotive parts, ring-shaped and sheet-shaped workpieces are widely used as accessories. Some ring-shaped and sheet-shaped workpieces are combined in an embedded manner. Specifically, through holes need to be machined on the sheet-shaped workpiece, and the ring-shaped workpiece is press-fitted into the through holes of the sheet-shaped workpiece.

[0003] However, most workpieces do not have a uniform shape, especially sheet-shaped workpieces, which have diverse shapes. It is difficult to design standard tooling to press-fit ring-shaped workpieces with sheet-shaped workpieces, so manual assembly is the only option. However, manual assembly requires a lot of labor costs, has low assembly efficiency, poor assembly quality, and is prone to rework, which is not conducive to high-efficiency production. Utility Model Content

[0004] This application provides an automated press-fitting fixture for automotive parts, which improves or solves the technical problems of high cost, low efficiency and poor quality in the manual assembly of ring-shaped and sheet-shaped workpieces in the existing automotive parts assembly process.

[0005] The technical solution adopted in this application is as follows:

[0006] An automated press-fitting fixture for automotive parts is used to press-fit annular and sheet-like workpieces. The automated press-fitting fixture includes a worktable and an upper positioning assembly and a lower positioning assembly respectively disposed on the worktable. The upper positioning assembly is used to position the annular workpiece, and the lower positioning assembly is used to position the sheet-like workpiece. The upper positioning assembly includes a drive mechanism and a positioning clamping mechanism connected to the drive mechanism. The positioning clamping mechanism includes two symmetrically arranged clamping members, which can move close to each other to clamp the annular workpiece or move away from each other to release the annular workpiece. The lower positioning assembly includes a positioning plate and a pressing member. The positioning plate is used to place the sheet-like workpiece, and the pressing member is rotatably disposed on the positioning plate, having a working position for pressing the sheet-like workpiece and a clearance position to avoid the sheet-like workpiece. The drive mechanism can drive the positioning clamping mechanism to move downwards, causing the annular workpiece clamped by the positioning clamping mechanism to press-fit with the sheet-like workpiece on the positioning plate.

[0007] The automated press-fitting fixture for automotive parts provided in this application also includes the following additional technical features:

[0008] The upper positioning component includes a positioning seat connected to the driving mechanism. The positioning clamping mechanism is located on the positioning seat. The bottom of the positioning seat is provided with a positioning post for positioning the annular workpiece. The two clamping members are located on both sides of the positioning post to clamp the annular workpiece on the positioning post when they are close to each other.

[0009] The positioning post includes a positioning section and a limiting section from bottom to top. The positioning section is used to fit the annular workpiece. The bottom end of the positioning section is provided with a guide slope for guiding the annular workpiece to fit upward. The diameter of the limiting section is larger than the diameter of the positioning section to form a stop and limit on the annular workpiece.

[0010] A clamping cylinder is installed on the positioning seat, which is used to drive the two clamping members to move closer to each other or further away from each other.

[0011] The driving mechanism is a lifting cylinder, the cylinder body of the lifting cylinder is fixed on the worktable, the piston rod of the lifting cylinder moves downward and extends out of the cylinder body, and the positioning seat is fixedly connected to the piston rod.

[0012] The positioning seat has guide posts extending vertically at both ends, and the worktable has guide holes adapted to the guide posts. The guide posts and the guide holes guide the positioning seat to move up and down through sliding cooperation.

[0013] The positioning plate is provided with multiple positioning blocks, which are used to horizontally stop and limit the sheet-like workpiece.

[0014] The lower positioning component includes a horizontal cylinder, the piston rod of which is connected to the positioning plate. The horizontal cylinder can drive the positioning plate to move back and forth in the horizontal direction through the extension and retraction of the piston rod.

[0015] The workbench is provided with a guide seat, the guide seat is provided with a guide groove, the positioning plate is confined within the guide groove, and is guided to slide through the guide groove.

[0016] The workbench includes a base plate and a top plate. The base plate supports the top plate via a support plate. The upper positioning component is mounted on the top plate, and the lower positioning component is mounted on the base plate.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least the following:

[0018] 1. The automated press-fitting fixture for automotive parts provided in this application has an upper positioning component for positioning an annular workpiece and a lower positioning component for positioning a sheet-like workpiece. After positioning the annular workpiece in the upper positioning component and the sheet-like workpiece in the lower positioning component, the upper positioning component moves the annular workpiece downward to achieve automatic press-fitting of the annular workpiece and the sheet-like workpiece. This helps save labor costs and improve assembly quality, resulting in high assembly efficiency and enabling high-efficiency production. The upper positioning component clamps the annular workpiece through two clamping parts of the positioning clamping mechanism, which has a simple structure and is easy to operate and control. The pressing part is rotatably mounted on the positioning plate and has a working position for pressing the sheet-like workpiece and an avoidance position for avoiding the sheet-like workpiece. Therefore, during the press-fitting process, the pressing part can press and position the sheet-like workpiece to prevent the sheet-like workpiece from jumping up and down on the positioning plate and interfering with the press-fitting process. After the press-fitting is completed, the pressing part can be rotated to detach from the sheet-like workpiece, making it easy to remove the sheet-like workpiece from the positioning plate.

[0019] 2. The bottom of the positioning seat is provided with a positioning post for positioning the annular workpiece, so that the annular workpiece can be pre-positioned on the positioning post, and the annular workpiece can be pre-positioned by the positioning post. Then, the annular workpiece is clamped by two clamping parts, thereby improving the convenience of installing and positioning the annular workpiece on the upper positioning component, and improving the reliability of the upper positioning component in positioning the annular workpiece.

[0020] 3. The positioning section of the positioning column is used to fit the annular workpiece. The bottom end of the positioning section is provided with a guide slope to guide the annular workpiece upward, which improves the smoothness of the annular workpiece being fitted into the positioning section and avoids jamming. The diameter of the limiting section is larger than that of the positioning section, so that when the annular workpiece is raised to fit into the positioning section, the limiting section forms a stop and limit on the annular workpiece, ensuring that the annular workpiece is fitted into the positioning section and restricting the annular workpiece from continuing to move upward and affecting the press fit with the sheet workpiece.

[0021] 4. The positioning plate is equipped with multiple positioning blocks, which are used to horizontally stop and limit the sheet-like workpiece to prevent it from sliding horizontally on the positioning plate and thus failing to achieve a successful press fit with the ring-shaped workpiece.

[0022] 5. The lower positioning component includes a horizontal cylinder, which can drive the positioning plate to move back and forth in the horizontal direction. In turn, the horizontal cylinder can move the press-fitted annular and sheet-shaped workpieces away from the worktable and into the preparation work for the next processing step.

[0039] In the embodiments of this application, an automated press-fitting fixture for automotive parts is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0040] like Figures 1 to 8As shown, this application provides an automated press-fitting fixture for automotive parts, used for press-fitting an annular workpiece 11 and a sheet-like workpiece 12. The automated press-fitting fixture includes a worktable 13 and an upper positioning assembly and a lower positioning assembly respectively disposed on the worktable 13. The upper positioning assembly is used to position the annular workpiece 11, and the lower positioning assembly is used to position the sheet-like workpiece 12. The upper positioning assembly includes a drive mechanism and a positioning clamping mechanism connected to the drive mechanism. The positioning clamping mechanism includes two symmetrically arranged clamping members 14, which can move closer to each other to clamp the annular workpiece 11 or move further apart to release the annular workpiece 11. Figure 1 and Figure 3 The diagram shows the state in which two clamping members 14 clamp the annular workpiece 11. The lower positioning assembly includes a positioning plate 15 and a pressing member 16. The positioning plate 15 is used to place the sheet-like workpiece 12, and the pressing member 16 is rotatably disposed on the positioning plate 15, having a working position for pressing the sheet-like workpiece 12 and a clearance position for avoiding the sheet-like workpiece 12. Figure 6 The image shows the state of the pressing member 16 when it is in the working position of pressing the sheet workpiece 12; the driving mechanism can drive the positioning clamping mechanism to move downward so that the annular workpiece 11 held by the positioning clamping mechanism is pressed into fit with the sheet workpiece 12 on the positioning plate 15.

[0041] It should be noted that the present application illustrates a schematic structural shape of the annular workpiece 11 and the sheet workpiece 12, which is not intended to limit the present application. The present solution can also be applied to the press fitting of annular workpieces and sheet workpieces with other structural shapes.

[0042] The automated press-fitting fixture for automotive parts provided in this application has an upper positioning component for positioning an annular workpiece 11 and a lower positioning component for positioning a sheet-like workpiece 12. After positioning the annular workpiece 11 in the upper positioning component and the sheet-like workpiece 12 in the lower positioning component, the upper positioning component moves the annular workpiece 11 downward to achieve automatic press-fitting of the annular workpiece 11 and the sheet-like workpiece 12. This helps save labor costs and improve assembly quality, resulting in high assembly efficiency and enabling high-efficiency production. The upper positioning component clamps and positions the annular workpiece 11 through two clamping parts 14 of the positioning clamping mechanism, which has a simple structure and is easy to operate and control. Specifically, the clamping member 14 can be used to clamp the top of the annular workpiece 11, leaving an area at the bottom of the annular workpiece 11 for press-fitting with the sheet workpiece 12; the pressing member 16 is rotatably disposed on the positioning plate 15 and has a working position for pressing the sheet workpiece 12 and a clearance position for avoiding the sheet workpiece 12. Therefore, during the pressing process, the pressing member 16 can press and position the sheet workpiece 12 to prevent the sheet workpiece 12 from jumping up and down on the positioning plate 15 and interfering with the pressing process. After the pressing is completed, the pressing member 16 can be rotated to detach from the sheet workpiece 12, making it easy to remove the sheet workpiece 12 from the positioning plate 15.

[0043] It should be further noted that this application does not specifically limit the method of driving the pressure member 16 to rotate. For example, the pressure member 16 can be rotated manually or automatically by a servo motor to improve the automation level of the tooling. Specifically, a vertically extending rotating shaft can be set on the positioning plate 15, and the rotating shaft and the pressure member 16 can be connected by a bearing to realize the rotatable design of the pressure member 16.

[0044] As a preferred embodiment of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the upper positioning assembly includes a positioning seat 17, which is connected to the driving mechanism. The positioning clamping mechanism is located on the positioning seat 17. The bottom of the positioning seat 17 has a positioning post 18 for positioning the annular workpiece 11. Two clamping members 14 are located on either side of the positioning post 18 to clamp the annular workpiece 11 onto the positioning post 18 when they are close together. Those skilled in the art will understand that by providing the positioning seat 17, the installation of the positioning clamping mechanism is facilitated, allowing the positioning seat 17 to move up and down synchronously with the positioning clamping mechanism when the driving mechanism moves the positioning seat 17 up and down. The bottom of the positioning seat 17 is provided with a positioning post 18 for pre-positioning the annular workpiece 11. This allows the annular workpiece 11 to be pre-fitted onto the positioning post 18, achieving pre-positioning of the annular workpiece 11. The annular workpiece 11 is then clamped by two clamping members 14, thereby improving the ease of installation and positioning of the annular workpiece 11 on the upper positioning assembly and enhancing the reliability of the upper positioning assembly's positioning of the annular workpiece 11. During actual press-fitting, the drive mechanism moves the positioning seat 17, the positioning clamping mechanism, and the annular workpiece 11 downwards together until the annular workpiece 11 is press-fitted with the sheet workpiece 12. Then, the two clamping members 14 move away from each other, releasing the annular workpiece 11. Finally, the drive mechanism moves the positioning seat 17 upwards, causing the positioning post 18 to disengage from the annular workpiece 11.

[0045] As a preferred embodiment of this implementation, such as Figure 4 and Figure 5As shown, the positioning post 18 includes a positioning section 181 and a limiting section 182 from bottom to top. The positioning section 181 is used to fit the annular workpiece 11. The bottom end of the positioning section 181 is provided with a guide slope 1811 for guiding the annular workpiece 11 to fit upward. The diameter of the limiting section 182 is larger than the diameter of the positioning section 181 to form a stop and limit on the annular workpiece 11. Those skilled in the art will understand that the bottom end of the positioning section 181 is provided with a guide slope 1811 for guiding the annular workpiece 11 to be fitted upwards, which improves the smoothness of the annular workpiece 11 being fitted upwards into the positioning section 181 and avoids jamming; the diameter of the limiting section 182 is larger than the diameter of the positioning section 181, so that when the annular workpiece 11 rises to fit into the positioning section 181, the limiting section 182 forms a stop and limit on the annular workpiece 11, so as to ensure that the annular workpiece 11 is fitted into place on the positioning section 181 and to limit the annular workpiece 11 from continuing to move upwards and affecting the press fit with the sheet workpiece 12.

[0046] As a preferred embodiment of this implementation, such as Figure 2 and Figure 3 As shown, a clamping cylinder 19 is mounted on the positioning seat 17. The clamping cylinder 19 is used to drive the two clamping members 14 to move closer to or further away from each other. The clamping cylinder 19 can perform a fast and stable clamping operation on the annular workpiece 11. As an alternative embodiment, the two clamping members 14 can also be moved closer to or further away from each other in other ways. For example, the two clamping members 14 can be connected to a screw with a reverse thread, and the screw can be driven to rotate by a motor, thereby driving the two clamping members 14 to move closer to or further away from each other through the reverse thread.

[0047] As a preferred embodiment of this implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the driving mechanism is a lifting cylinder 20, the cylinder body of which is fixed to the worktable 13. The piston rod of the lifting cylinder 20 moves downward and extends out of the cylinder body, and the positioning seat 17 is fixedly connected to the piston rod. Further, as... Figure 1 , Figure 3 and Figure 4 As shown, the positioning seat 17 has guide posts 171 extending vertically at both ends, and the worktable 13 has guide holes adapted to the guide posts 171. The guide posts 171 and the guide holes guide the positioning seat 17 to move up and down through sliding cooperation, which improves the reliability and stability of the lifting cylinder 20 driving the positioning seat 17 to move up and down, and enables the annular workpiece 11 and the sheet workpiece 12 to be precisely matched.

[0048] As a preferred embodiment of this application, such as Figure 6 and Figure 7As shown, the positioning plate 15 is provided with multiple positioning blocks 21. These positioning blocks 21 are used to horizontally stop and limit the sheet-like workpiece 12, preventing it from sliding horizontally on the positioning plate 15 and thus failing to achieve a successful press-fit with the annular workpiece 11. In specific implementation, the positions of the positioning blocks 21 can be arranged according to the specific structure of the sheet-like workpiece 12. For example, multiple positioning blocks 21 can form a limiting cavity that roughly matches the contour of the sheet-like workpiece 12, thus providing multi-position and multi-directional stopping and limiting for the sheet-like workpiece 12. Specifically, positioning holes can be provided on the positioning plate 15, and the positioning blocks 21 can be inserted into these holes.

[0049] As a preferred embodiment of this application, such as Figure 2 , Figure 6 and Figure 7 As shown, the lower positioning assembly includes a horizontal cylinder 22, the piston rod of which is connected to the positioning plate 15. The horizontal cylinder 22 can drive the positioning plate 15 to move back and forth in the horizontal direction through the extension and retraction of the piston rod. Those skilled in the art will understand that after the annular workpiece 11 and the sheet workpiece 12 are pressed together, the positioning plate 15 can be slid under the drive of the horizontal cylinder 22, thereby removing the pressed annular workpiece 11 and the sheet workpiece 12 from the worktable 13 to prepare for the next processing step. After the pressed annular workpiece 11 and the sheet workpiece 12 are removed from the positioning plate 15, the horizontal cylinder 22 drives the positioning plate 15 to reset, thus preparing for the pressing of the next set of annular workpieces 11 and sheet workpieces 12.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, the worktable 13 is provided with a guide seat 23, the guide seat 23 is provided with a guide groove 231, the positioning plate 15 is confined within the guide groove 231 and is guided to slide through the guide groove 231, so as to ensure that the positioning plate 15 slides reliably and stably under the driving action of the horizontal cylinder 22.

[0051] As a preferred embodiment of this application, such as Figure 1 , Figure 2 and Figure 8As shown, the workbench 13 includes a base plate 131 and a top plate 132. The base plate 131 supports the top plate 132 via a support plate 133. The upper positioning component is installed on the top plate 132, and the lower positioning component is installed on the base plate 131. An assembly space is formed between the top plate 132 and the base plate 131. Specifically, the cylinder body of the lifting cylinder 20 can be fixedly installed above the top plate 132. The top plate 132 is provided with a through hole to avoid the piston rod of the lifting cylinder 20. The positioning and clamping mechanism is located between the top plate 132 and the base plate 131. The workbench 13 of this application has a simple overall structure and occupies a small area.

[0053] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0054] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
