Description

Technical Field

[0001] This utility model relates to the field of rolling processing technology, and in particular to a rolling device. Background Technology

[0002] The ABS solenoid valve is a core component of the anti-lock braking system, which prevents wheel lock-up by precisely controlling braking pressure. The solenoid valve contains a variety of pipe and shaft parts, and the outer surfaces of these parts need to be finely rolled to improve the surface finish and dimensional accuracy of the parts, so as to meet the stringent requirements of the ABS solenoid valve for high reliability of the components.

[0003] In existing technologies, tube and shaft parts are mostly rolled manually by operators. However, due to the small outer diameter and high surface quality requirements of the tube and shaft parts to be processed, manual operation makes it difficult to ensure the stability and consistency of rolling, resulting in a low rolling yield. During manual rolling, tube and shaft parts are easily affected by factors such as touching and bumping by operators, causing dirt and dents, which further affect the quality and performance of the product. In addition, manual rolling leads to low production efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] Therefore, it is necessary to provide a rolling device to address the problems of difficulty in ensuring the stability and consistency of rolling, poor product quality and performance after rolling, and low production efficiency in the existing technology of manually rolling tubes and shaft parts.

[0005] The technical solution adopted in this utility model is as follows: A rolling device includes a support mechanism, a rotary drive module arranged on one side of the support mechanism, and a pressing drive mechanism arranged on the other side of the support mechanism, wherein the working end of the pressing drive mechanism is connected to a pressure roller. The top of the support mechanism supports the workpiece, and the workpiece is clamped and rotated by the rotation drive module. The downward driving mechanism drives the pressure roller to move in a vertical linear motion, so that the outer surface of the pressure roller contacts the outer wall surface of the rotating workpiece, and then the workpiece is rolled by the pressure roller.

[0006] As a further improvement to the above technical solution: The rotary drive module includes a servo motor, the output end of which is connected to a pneumatic chuck via a transmission mechanism. The pneumatic chuck clamps the workpiece when it is ventilated and releases the workpiece when the pneumatic chuck is de-ventilated. When the pneumatic chuck holds the workpiece, the servo motor drives the pneumatic chuck to rotate through the transmission mechanism, thereby causing the workpiece to rotate.

[0007] The transmission mechanism has the following structure: it includes a driving wheel connected to the output end of a servo motor and a driven wheel. A synchronous belt is installed between the driven wheel and the driving wheel. The driven wheel is fixed to the input shaft end of the gearbox. The output shaft of the gearbox is connected to a pneumatic chuck.

[0008] The outer wall of the gearbox is fixed with a mounting bracket to support the servo motor.

[0009] The rotary drive module is supported by a base plate. A first centering groove is formed on the top of the base plate, and a second centering groove is formed on the bottom wall of the gearbox. Centering blocks are installed in both the second and first centering grooves, thereby positioning the gearbox by means of the centering blocks.

[0010] The structure of the support mechanism is as follows: it includes a fixed seat, a sliding groove is opened on the side wall of the fixed seat, an adjusting seat is installed in the sliding groove, and symmetrically arranged follower wheels are installed on the adjusting seat. The workpiece is supported by the two follower wheels, and the two follower wheels rotate with the rotating workpiece.

[0011] The fixed base has bolt holes, and an adjusting bolt is installed in the bolt holes. The head of the adjusting bolt abuts against the bottom end face of the adjusting base, and an adjusting nut is installed on the outer circumference of the adjusting bolt. Rotate the adjusting bolt to push the adjusting seat to slide along the slide groove, thereby adjusting the installation height of the adjusting seat.

[0012] The top end face of the adjustment seat is provided with a concave arc surface.

[0013] The structure of the downward driving mechanism is as follows: it includes a servo module, the output end of which is connected to the pressure plate through a floating component, the bottom of the pressure plate is fixedly connected to a base, a mounting shaft is mounted on the base, and a pressure roller is mounted on the outer circumference of the mounting shaft through a bearing assembly; The servo module drives the pressure plate to move downward in a vertical linear motion, thereby causing the pressure roller to descend and making the outer circumferential surface of the pressure roller contact the outer circumferential surface of the workpiece.

[0014] The floating component includes a floating stage cylinder connected to the output end of the servo module. The output end of the floating stage cylinder is connected to a connector, which is connected to the pressure plate. The floating table cylinder extends or retracts, thereby driving the pressure roller to float vertically via the pressure plate, thus adjusting the pressure of the pressure roller on the workpiece during rolling.

[0015] The beneficial effects of this utility model are as follows: This utility model has a compact and reasonable structure and is easy to operate. By setting up a rotary drive module, a support mechanism, a pressing drive mechanism and a pressure roller, it can automatically roll the workpiece, effectively improve the stability and consistency of rolling, increase the rolling yield, improve the quality and performance of the rolled product, and has high production efficiency, which can meet the needs of large-scale production.

[0019] (4) By setting bolt holes, adjusting bolts and adjusting nuts, the installation height of the adjusting seat can be adjusted, thereby matching workpieces of different diameters and effectively improving the flexibility of the rolling device.

[0020] (5) In this utility model, by setting a floating table cylinder, the pressure roller adaptively adjusts the pressure on the workpiece, ensuring uniform rolling, avoiding damage to the workpiece, and improving the rolling quality and product qualification rate.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0033] The structure and function of this utility model are as follows: like Figures 1-8 As shown, a rolling device includes a support mechanism 5, a rotary drive module arranged on one side of the support mechanism 5, and a downward drive mechanism 6 arranged on the other side of the support mechanism 5. The working end of the downward drive mechanism 6 is connected to a pressure roller 8. The top of the support mechanism 5 supports a workpiece 9, which is clamped and rotated by the rotary drive module. The downward drive mechanism 6 drives the pressure roller 8 to move downward in a vertical direction, so that the outer surface of the pressure roller 8 contacts the outer wall surface of the rotating workpiece 9, thereby rolling the workpiece 9. By setting up the rotary drive module, the support mechanism 5, the downward drive mechanism 6, and the pressure roller 8, the workpiece 9 can be automatically rolled, effectively improving the rolling stability and consistency, increasing the rolling yield, improving the quality and performance of the rolled product, and achieving high production efficiency, which can meet the needs of large-scale production. like Figure 8 As shown, the workpiece 9 in this utility model is a combination of two sleeves, which is a slender tube-like part; in addition, the rolling device of this utility model can also perform rolling treatment on slender shaft-like parts.

[0034] like Figures 1-2 As shown, the rotary drive module includes a servo motor 1. The output end of the servo motor 1 is connected to a pneumatic chuck 2 via a transmission mechanism 3. The pneumatic chuck 2 clamps the workpiece 9 when air is supplied, and releases the workpiece 9 when air is cut off. When the pneumatic chuck 2 clamps the workpiece 9, the servo motor 1 drives the pneumatic chuck 2 to rotate via the transmission mechanism 3, thereby driving the workpiece 9 to rotate. By setting the pneumatic chuck 2, stable clamping of the workpiece 9 can be achieved; by setting the transmission mechanism 3, the torque output by the servo motor 1 can be transmitted, thereby driving the workpiece 9 to rotate via the pneumatic chuck 2.

[0035] The transmission mechanism 3 has the following structure: it includes a drive wheel 303 connected to the output end of the servo motor 1, and a driven wheel 305. A synchronous belt 304 is installed between the driven wheel 305 and the drive wheel 303. The driven wheel 305 is fixed to the input shaft end of the gearbox 301. The output shaft of the gearbox 301 is connected to the pneumatic chuck 2. The servo motor 1 drives the drive wheel 303 to rotate, and the drive wheel 303 drives the driven wheel 305 to rotate through the synchronous belt 304, thereby driving the input shaft of the gearbox 301 to rotate. Under the action of the gear assembly inside the gearbox 301, the output shaft of the gearbox 301 rotates, thereby driving the pneumatic chuck 2 to rotate, and in turn driving the workpiece 9 held by the pneumatic chuck 2 to rotate.

[0036] The outer wall of the gearbox 301 is fixed with a mounting base 302 for supporting the servo motor 1. By setting the mounting base 302, the servo motor 1 can be stably supported, and the structural compactness of the rolling device can be improved.

[0037] The rotary drive module is supported by a base plate 4. A first centering groove is formed on the top of the base plate 4, and a second centering groove is formed on the bottom wall of the gearbox 301. Centering blocks 306 are installed in both the second and first centering grooves, thereby positioning the gearbox 301 by means of the centering blocks 306. By setting the centering blocks 306, the gearbox 301 can be positioned quickly and accurately, ensuring stable transmission and improving the operating accuracy and reliability of the rolling device.

[0038] like Figures 3-4 As shown, the structure of the support mechanism 5 is as follows: it includes a fixed base 501, a sliding groove 508 is formed on the side wall of the fixed base 501, an adjusting base 502 is installed in the sliding groove 508, and symmetrically arranged follower wheels 503 are installed on the adjusting base 502. The two follower wheels 503 support the workpiece 9 and rotate with the rotating workpiece 9. The support mechanism 5 is fixed to the top of the base plate 4 and is used to support the workpiece 9; by setting two symmetrically arranged follower wheels 503, it can rotate with the workpiece 9, reduce friction resistance, improve the rotational stability of the workpiece 9, and ensure the rolling quality.

[0039] The fixed base 501 has bolt holes 506, and an adjusting bolt 505 is installed in the bolt holes 506. The head of the adjusting bolt 505 abuts against the bottom end face of the adjusting base 502, and an adjusting nut 504 is installed on the outer surface of the adjusting bolt 505. Rotating the adjusting bolt 505 pushes the adjusting base 502 to slide along the slide groove 508, thereby adjusting the installation height of the adjusting base 502. By setting the bolt holes 506, adjusting bolts 505, and adjusting nuts 504, the installation height of the adjusting base 502 can be adjusted, thus matching workpieces 9 of different diameters and effectively improving the flexibility of the rolling device.

[0040] The top end face of the adjusting seat 502 is provided with a concave arc surface 507. The concave arc surface 507 is arranged between the two follower wheels 503 to avoid the workpiece 9.

[0041] like Figures 5-7 As shown, the structure of the downward pressure drive mechanism 6 is as follows: it includes a servo module 601, the output end of which is connected to the pressure plate 603 through a floating component, the bottom of the pressure plate 603 is fixedly connected to a base 609, a mounting shaft 610 is mounted on the base 609, and a pressure roller 8 is mounted on the outer circumferential surface of the mounting shaft 610 through a bearing assembly; the servo module 601 drives the pressure plate 603 to make a downward linear motion in the vertical direction, thereby driving the pressure roller 8 to descend, so that the outer circumferential surface of the pressure roller 8 contacts the outer circumferential surface of the workpiece 9. The downward driving mechanism 6 is used to drive the pressure roller 8 to apply pressure to the workpiece 9. The downward driving mechanism 6 is supported by the mounting bracket 7, which is fixed to the top of the base plate 4. Two guide pillars 605 symmetrically arranged relative to the servo module 601 are installed on the top of the pressure plate 603. Each guide pillar 605 is fixed to the top of the pressure plate 603 by the support 607. Each guide pillar 605 is installed in cooperation with the mounting bracket 7 through the linear bearing 606. Limiting plates 604 are installed on the top of both guide pillars 605. By setting the guide pillars 605 and the linear bearings 606, the stability of the linear movement of the pressure plate 603 can be improved. By setting the limiting plates 604, the guide pillars 605 can be prevented from coming out of the corresponding linear bearings 606.

[0042] The floating component includes a floating stage cylinder 602 connected to the output of the servo module 601. The output of the floating stage cylinder 602 is connected to a connector 608, which in turn connects to a pressure plate 603. The floating stage cylinder 602 extends or retracts, thereby causing the pressure roller 8 to float vertically via the pressure plate 603, thus adjusting the pressure of the pressure roller 8 on the workpiece 9 during rolling. By setting up the floating component, the pressure roller 8 adaptively adjusts the pressure on the workpiece 9, ensuring uniform rolling, preventing damage to the workpiece 9, and improving rolling quality and product qualification rate.

[0043] In this utility model, such as Figure 7As shown, the mounting shaft 610 is concentrically mounted with the pressure roller 8, and the mounting shaft 610 is fixed to the connecting seat 609 by a baffle 612; the bearing assembly includes two slewing bearings 611, and the two adjacent slewing bearings 611 and one slewing bearing 611 and one inner wall of the connecting seat 609 are separated by a spacer 613; the mounting shaft 610 is a stepped shaft, and at least one shoulder is formed on its outer circumference, which separates the other slewing bearing 611 from the other inner wall of the connecting seat 609, thereby avoiding interference of the connecting seat 609 with the rotational movement of the pressure roller 8.

[0044] The working process of this utility model is as follows: First, place the workpiece 9 between the two follower wheels 503, and push one end of the workpiece 9 into the pneumatic chuck 2; Subsequently, the pneumatic chuck 2 is ventilated and clamps the workpiece 9. The servo motor 1 is started and drives the pneumatic chuck 2 to rotate through the transmission mechanism 3, thereby causing the workpiece 9 to rotate. Next, the servo module 601 is started, and the pressure roller 8 is pushed down vertically to the designated position through the connecting seat 609, so that the outer circumferential surface of the pressure roller 8 contacts the outer circumferential surface of the corresponding workpiece 9 and rolls the workpiece 9. Finally, after the rolling process is complete, all components are reset and ready for the next rolling process.
