Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a rim forming device. Background Art

[0002] The rim, commonly known as the wheel ring, refers to the component around the wheel that installs and supports the tire. It is a large-diameter cylindrical workpiece. The rim and the spokes together bear the wheel load and dissipate the heat generated by the tire. The rim is usually made of high-strength, corrosion-resistant copper alloy, aluminum alloy, steel and other metal materials. It has the characteristics of wear resistance, corrosion resistance, and impact resistance. During the processing and forming of the rim, grinding equipment is required to grind the circumferential surfaces at the upper and lower ends to remove burrs and edge welds.

[0003] Existing rim grinding and forming equipment generally grinds the end face of the rim directly. However, since the rim is usually welded together from three sections of steel plate coils during the early processing, the positions of welds and burrs are randomly and irregularly distributed. Although most of the welds and burrs can be removed by directly using equipment for automatic grinding, a few grinding dead corners will still remain. If manual grinding is used, although the grinding dead corners can be reduced, the labor intensity is high and the forming quality of the rim will vary from person to person.

In the present embodiment, the chuck jaw 301 adopts a rotating chuck jaw. When the chuck jaw 301 contacts the rim, the two symmetrically arranged chucks at the front end of the chuck jaw 301 will be subjected to the reaction pressure of the rim and rotate inward, thereby causing the two chucks to automatically adapt to the arc surface of the rim, so that the clamping of the plurality of chuck jaws 301 is more stable. Figure 1As shown, a lifting frame 5 is fixedly installed on the top of the workbench 1. In this embodiment, the lifting frame 5 is driven by a linear actuator such as an electric push rod or a pneumatic element as a power structure, so that the lifting frame 5 can be lifted up and down, and a multi-angle grinding component is arranged on one side of the lifting frame 5. Specifically, when the rim forming equipment is used, the rim is first placed on the placement table 4, and the clamping electric push rod 3 on the peripheral side drives the chuck jaw 301 to move close to the rim until the rim is clamped and fixed;

[0040] The multi-angle grinding assembly is used to grind various places on the end surface of the rim;

[0041] like Figure 3 As shown, the multi-angle grinding assembly includes a grinding motor 6 fixedly mounted on one side of the top of the lifting frame 5, and an adjusting disk 7 is fixedly mounted on the output shaft of the grinding motor 6. Figure 4 As shown, a plurality of adjusting electric slide rails 8 evenly distributed along the axis of the output shaft of the grinding motor 6 are fixedly installed at the bottom of the adjusting plate 7. Figure 5 As shown, the bottom of the adjustable electric slide rail 8 is driven to be installed with an electric slide seat 9, the bottom of the electric slide seat 9 is fixedly installed with a suspension frame 10, and the bottom end of the suspension frame 10 is rotatably installed with two adjustment shafts 1001, as shown in FIG. Fig. 9As shown, a same mounting frame 11 is fixedly installed between two steering shafts 1001 located on the same side, a docking plate 12 is arranged inside the mounting frame 11, and grinding plates 13 are fixedly installed on the top and bottom of the docking plate 12.

A steering motor 14 and a torque sensor 15 are fixedly installed on both sides of the suspension frame 10, respectively. The output shaft of the steering motor 14 and the induction shaft of the torque sensor 15 are respectively connected to the two steering shafts 1001. In this embodiment, the steering motor 14 has a self-locking mechanism, such as a mechanical lock and an electromagnetic lock; specifically, by setting a multi-angle grinding assembly, when grinding, the electric slide rail 8 is adjusted to drive the electric slide seat 9 to move linearly, and then the grinding plate 13 is driven to move above the rim end surface through the suspension frame 10 and the mounting frame 11, so that the grinding plate 13 can be moved to the position where grinding is required, and then the steering motor 14 drives the steering shaft 1001 to rotate a certain angle, so that the mounting frame 11 and the grinding plate 13 rotate to be tangent to the current position of the rim end surface, and finally the grinding motor 6 drives the adjusting disk 7 to rotate, so that each grinding plate 1 3. The rim end face is ground to obtain a better grinding effect, realize multi-angle grinding, and ensure the grinding quality. By setting the torque sensor 15, when a type of rim is ground for the first time, the lifting frame 5 drives the multi-angle grinding assembly to descend to the top of the rim, but does not contact the rim end face. Then the steering motor 14 releases the lock of the steering shaft 1001, so that the steering shaft 1001 can rotate freely at the bottom of the suspension frame 10. The mounting frame 11, the docking plate 12 and the grinding plate 13 drive the steering shaft 1001 to rotate downward under the action of gravity, so that the bottom grinding plate 13 The grinding plate 13 is in contact with the end face of the rim, and then the lifting frame 5 is finely adjusted in height to make the grinding plate 13 tangent to the end face of the rim. At this time, the torque sensor 15 records the rotation angle of the steering shaft 1001, and the steering motor 14 locks the steering shaft 1001, adjusts the electric slide rail 8 to drive the electric slide seat 9 to change the position of the grinding plate 13, and repeats the above operations. Through the mutual cooperation of the grinding plate 13, the steering motor 14 and the torque sensor 15, the angle data of each part of the rim end face is obtained, so that when facing the same model of rim in the future, the previously measured data can be directly called to achieve accurate and fast multi-angle grinding.

[0042] like Figure 6 As shown, a central shaped rod 16 is fixedly installed on the top of the placement table 4, and the position of the central shaped rod 16 is consistent with the position of the axis of the output shaft of the grinding motor 6, as shown in FIG. Figure 7As shown, an inner support sleeve 17 is sleeved on the center special-shaped rod 16, and a special-shaped positioning hole 18 matched with the center special-shaped rod 16 is opened at the bottom of the inner support sleeve 17; specifically, by setting the center special-shaped rod 16, before placing the rim, the inner support sleeve 17 matched with the rim model to be currently polished can be sleeved on the center special-shaped rod 16, and then the rim is sleeved on the inner support sleeve 17, and then the electric push rod 3 and the chuck jaws 301 are clamped and fixed to the rim, and the inner support sleeve 17 inside the rim provides internal support for the rim, which can, on the one hand, prevent the rim from being concave due to excessive clamping force of the chuck jaws 301, and on the other hand, prevent the end face of the rim from being deformed due to vibration caused by polishing.

[0043] like Figure 8 As shown, a fastening thread groove is provided at the top of the center special-shaped rod 16, a fastening screw 19 is screwed inside the fastening thread groove, a fastening knob 20 is fixedly installed at the top of the fastening screw 19, a fastening sleeve 21 is rotatably sleeved at the bottom end of the fastening knob 20, and the bottom of the fastening sleeve 21 contacts the top of the inner support sleeve 17; specifically, by providing the fastening sleeve 21, after the inner support sleeve 17 is sleeved, the fastening screw 19 can be aligned with the fastening thread groove at the top of the center special-shaped rod 16 and screwed, so that the fastening screw 19 drives the fastening sleeve 21 descends and fits closely against the top end face of the inner support sleeve 17, pressing the inner support sleeve 17 against the top of the placement table 4 to prevent the inner support sleeve 17 from shaking up and down during grinding. At the same time, when it is necessary to grind the lower end face of the rim, the fastening sleeve 21 and other components can be removed, the rim and the inner support sleeve 17 can be reversely sleeved on the center special-shaped rod 16, and then the fastening sleeve 21 can be pressed against the end face of the inner support sleeve 17 again, so that the multi-angle grinding assembly can grind the lower end face of the rim. If it is necessary to grind the inner ring of the rim, the inner support sleeve 17 can be removed.

[0044] like Figure 7 As shown, a plurality of positioning protrusions 22 evenly distributed along the special-shaped positioning holes 18 are fixedly installed on the top of the inner support sleeve 17; specifically, by setting the positioning protrusions 22, if the rim to be polished and the spoke plate are an integrated structure, the inner support sleeve 17 with the positioning protrusions 22 can be selected to support the rim, so that each positioning protrusion 22 is inserted into each mounting hole on the spoke plate from the bottom, and the spoke plate is positioned to keep the spoke plate and the rim positioned, thereby preventing the spoke plate from being subjected to the friction force of polishing and generating a tendency to axially rotate, causing the weld or connection structure between the spoke plate and the rim to be deformed or even broken.

[0045] like Fig. 9As shown, a plurality of sockets are provided on both sides of the mounting frame 11, and a plurality of mounting through holes 23 are provided inside the docking plate 12, and the mounting through holes 23 on the same side are connected with the two sockets; specifically, by providing the sockets and the mounting through holes 23, fastening bolts can be provided inside the two sockets and the mounting through holes 23 at the same place to fix the docking plate 12 and the mounting frame 11, so that the grinding plate 13 is a detachable structure, and after the grinding plate 13 is subjected to grinding operation for a long time, the degree of wear of the grinding plate 13 can be detected. If the degree of wear of the grinding plate 13 is too high, the fastening bolts can be removed to separate the mounting frame 11 and the docking plate 12, and the docking plate 12 and the grinding plate 13 can be replaced to ensure the grinding quality of the molding equipment.

[0046] like Figure 5 As shown, the two sockets on the same side are both plugged with mounting rods 24, and the ends of the two mounting rods 24 that are away from each other are fixedly mounted with mounting knobs 25, and the other ends of the two mounting rods 24 extend to the inside of the mounting through hole 23, as shown in FIG. Fig.10 As shown, one end of one of the mounting docking rods 24 is fixedly installed with a mounting screw 26, and one end of the other mounting docking rod 24 is provided with a mounting threaded groove compatible with the mounting screw 26; specifically, by providing the mounting docking rod 24, the two mounting docking rods 24 can replace the traditional fastening bolts. When installing the docking plate 12, the two matching mounting docking rods 24 can be inserted from the jacks at both ends of the mounting through hole 23 respectively, and docked inside the mounting through hole 23, and then the mounting knobs 25 at both ends are rotated to make the mounting screw 26 at one end of one of the mounting docking rods 24 screw into the inside of the mounting threaded groove at one end of the other mounting docking rod 24, so that the two mounting docking rods 24 are screwed together, and the threads of the mounting screw 26 are received in the inside of the mounting docking rod 24 for protection, which greatly reduces the impact of vibration and impact generated during grinding, avoids the problem of easy wear and slippage of the threads of traditional fastening bolts, and allows the mounting docking rod 24 to be reused for a long time.

[0047] like Figure 6 As shown, a lifting platform 27 is fixedly installed on the top of the workbench 1, and the placement table 4 is fixedly installed on the top of the lifting platform 27; specifically, by setting the lifting platform 27, the lifting platform 27 can drive the placement table 4 to move up and down, so that the rim is moved to a suitable position, so that the clamping electric push rod 3 and the chuck jaws 301 can effectively clamp the rim.

[0048] like Figure 2 As shown, a collecting annular box 28 is fixedly installed at the bottom of the placing table 4. Figure 1As shown, a dust baffle 29 is fixedly installed on the top of the workbench 1; specifically, by providing a collecting ring box 28, it is convenient for the staff to sweep the grinding waste accumulated on the placement table 4 into the collecting ring box 28 to avoid affecting the stable support of the placement table 4 for the rim. The dust baffle 29 can block most of the waste inside the equipment to avoid affecting the workshop environment.

[0049] In summary: before grinding: first, sleeve the inner support sleeve 17 that matches the rim model to be grinded on the center special-shaped rod 16, align the fastening screw 19 with the fastening thread groove at the top of the center special-shaped rod 16 and screw it, so that the fastening screw 19 drives the fastening sleeve 21 to descend and close to the top end surface of the inner support sleeve 17, press the inner support sleeve 17 on the top of the placement table 4, then sleeve the rim on the inner support sleeve 17, and then place the rim on the placement table 4, and the clamping electric push rod 3 on the circumferential side drives the chuck jaw 301 to move close to the rim until the rim is clamped and fixed;

[0050] During grinding: the electric slide rail 8 is adjusted to drive the electric slide seat 9 to move linearly, and then the grinding plate 13 is driven to move above the rim end surface through the suspension frame 10 and the mounting frame 11, so that the grinding plate 13 can be moved to the position where grinding is required, and then the steering motor 14 drives the steering shaft 1001 to rotate a certain angle, so that the mounting frame 11 and the grinding plate 13 rotate to be tangent to the current position of the rim end surface, and finally the grinding motor 6 drives the adjustment disk 7 to rotate, so that each grinding plate 13 grinds the rim end surface;

[0051] After grinding: remove the wheel rim and start the next round of grinding. If the grinding plate 13 is too worn, remove the mounting docking rod 24 to separate the mounting frame 11 and the docking plate 12, replace the docking plate 12 and the grinding plate 13, insert the two matching mounting docking rods 24 from the jacks at both ends of the mounting through hole 23, and dock them inside the mounting through hole 23, then rotate the mounting knobs 25 at both ends to screw the mounting screw 26 at one end of one mounting docking rod 24 into the inside of the mounting thread groove at one end of the other mounting docking rod 24, so that the two mounting docking rods 24 are screwed together, and the replacement is completed;

[0052] Rim data measurement: When grinding a certain type of rim for the first time, the lifting frame 5 drives the multi-angle grinding assembly to descend to the top of the rim, but does not contact the end face of the rim. Then the steering motor 14 releases the lock on the steering shaft 1001, so that the steering shaft 1001 can rotate freely at the bottom of the suspension frame 10. The mounting frame 11, the docking plate 12 and the grinding plate 13 drive the steering shaft 1001 to rotate downward under the action of gravity, so that the bottom grinding plate 13 contacts the end face of the rim. Then the lifting frame 5 moves forward. Fine-tune the height so that the grinding plate 13 is tangent to the end face of the rim. At this time, the torque sensor 15 records the rotation angle of the steering shaft 1001, and the steering motor 14 locks the steering shaft 1001. The electric slide rail 8 is adjusted to drive the electric slide seat 9 to change the position of the grinding plate 13. Repeat the above operation, and obtain the angle data of each part of the end face of the rim through the mutual cooperation of the grinding plate 13, the steering motor 14 and the torque sensor 15, so that when facing the same type of rim in the future, the previously measured data can be directly called.
