Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures, specifically to a rotary fixture for coating processing of plastic hardware composite parts. Background Technology

[0002] During the coating process of plastic-metal composite parts, tooling is required to position and clamp the workpiece to ensure its stability and full contact with the coating medium. Existing coating tooling typically includes a fixture table, clamping components, and a drive mechanism. The drive mechanism often uses a single motor as a power source, which can only drive the fixture table to rotate circumferentially. Although some tooling has angle adjustment functions, this is mostly accomplished by manually tightening bolts or simple linkage structures, and the adjustment process relies on manual operation. The clamping components are mostly fixed clamping plates that are rigidly connected to the fixture table and are not equipped with transmission components that can dynamically adjust them.

[0003] The existing tooling lacks a dedicated drive structure to drive the transmission frame, and can only achieve circumferential rotation through a single motor. It cannot flexibly adjust the left and right angles of the tooling table. When facing irregular structures such as protrusions and grooves on the workpiece, it is difficult to ensure that these parts fully contact the coating medium, resulting in coating omissions in deep cavities and corners of the workpiece. Furthermore, the existing angle adjustment does not use a stepper motor drive, and manual or simple adjustment methods cannot accurately control the tilt angle, further leading to uneven coating. This makes it difficult to form a complete coating layer in key areas such as the connection between plastic and hardware, ultimately resulting in insufficient wear resistance and corrosion resistance of the product, requiring frequent rework to correct coating defects. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a rotary tooling for coating processing of plastic hardware composite parts. When clamping, it can improve the uniformity of coating on the workpiece and the convenience of clamping, and solve the technical problem that coating omissions are easy to occur after clamping in the prior art.

[0005] The objective of this utility model is achieved through the following means: A rotary fixture for coating processing of plastic-metal composite parts includes a base plate. A first motor is mounted on the upper surface of the base plate. A mounting base is connected to the upper surface of the base plate at the output end of the first motor. A bearing is inserted inside the mounting base. A transmission frame is inserted inside the bearing. A second motor is mounted on the lower part of the transmission frame. The rotor of the second motor passes through the corresponding position of the transmission frame. A fixture table is coaxially connected to the top of the rotor of the second motor. Hinges are connected to both sides of the upper surface of the fixture table. An assembly seat is hinged to the inner side of the hinges. A clamping plate is mounted on the top of the assembly seat. A bracket is mounted on the upper surface of the fixture table. A third motor is mounted outside the bracket. A drive component is coaxially connected to the rotor of the third motor. A transmission rod is inserted inside the assembly seat.

[0006] Furthermore, the rotor of the first motor passes through the interior of the bearing, and the outer end of the rotor of the first motor is connected to the corresponding position on the outside of the transmission frame. The rotor of the first motor passes through the bearing and connects to the transmission frame. The bearing reduces transmission friction, making the transmission more stable, reducing component wear, ensuring precise and smooth adjustment of the tooling's left and right angles, and improving operational reliability.

[0007] Furthermore, the bottom of the second motor is connected to a base rod, and a mounting plate is installed on the upper surface of the base plate at a position corresponding to the base rod. An arc-shaped frame is provided on the top of the mounting plate, and a guide rail is installed on the top of the arc-shaped frame. The base rod at the bottom of the second motor cooperates with the arc-shaped frame and guide rail on the base plate to provide stable support for the second motor and transmission frame, adapt to the rotation trajectory, avoid shaking, ensure smooth circumferential rotation of the tooling table, and enhance the structural load-bearing capacity.

[0008] Furthermore, a roller is hinged to the bottom of the base rod, the roller is inserted inside the guide rail, and a rubber sleeve is fitted on the outside of the roller. The bottom roller of the base rod is embedded in the guide rail. The rubber sleeve increases friction and reduces vibration, which reduces movement resistance and operating noise, avoids hard friction wear of parts, and improves the overall stability and durability of the tooling.

[0009] Furthermore, the interior of the mounting base is connected to the inner end of the transmission rod via a rotating shaft. The outer side of the driving component is inclined, and the outer end of the transmission rod is connected to the inclined position of the driving component. The mounting base is connected to the transmission rod via a bearing, which works in conjunction with the inclined driving component to reduce wear on the transmission rod, making the power transmission smoother, ensuring stable reciprocating swing of the mounting base, and ensuring uniform contact of all parts of the workpiece with the coating medium.

[0010] Furthermore, a damping shock absorber ring is provided between the bearing and the mounting base. The damping shock absorber ring consists of two metal rings, an inner and an outer layer, and a silicone damping layer sandwiched between them. The damping shock absorber ring between the bearing and the mounting base absorbs vibration through the silicone layer and the metal rings reinforce the structure, reducing the transmission of vibration during motor operation, protecting various components, improving the stability of tooling operation, and extending service life.

[0011] The beneficial effects of this invention are as follows: The first motor drives the transmission frame to rotate, thereby adjusting the tooling table's left and right angles. Simultaneously, the second motor drives the tooling table's circumferential rotation, and the third motor drives the drive component and transmission rod to rotate, causing the assembly base and clamping plate to reciprocate. This ensures that all surfaces of the plastic-metal composite parts are evenly contacted with the coating medium, avoiding the localized coating omissions common in traditional fixed tooling. It ensures a complete coating layer is formed at critical areas such as the connection between plastic and metal. The left and right tilt adjustment driven by the first motor can accommodate irregular structures such as protrusions and grooves on the workpiece, ensuring full coating coverage in difficult-to-plate areas. Furthermore, the reciprocating back-and-forth swing of the clamping plate driven by the third motor further covers easily overlooked areas such as deep cavities and corners of the workpiece, solving the problem of uneven coating, improving the product's wear and corrosion resistance, reducing rework due to coating defects, and enhancing the quality of the tooling.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] In this embodiment, refer to Figures 1-5 The specific implementation of the rotary tooling for coating processing of plastic hardware composite parts includes a base plate 1, a first motor 2 mounted on the upper surface of the base plate 1, a mounting base 3 connected to the upper surface of the base plate 1 at the output end of the first motor 2, a bearing 4 inserted inside the mounting base 3, a transmission frame 5 inserted inside the bearing 4, the rotor of the first motor 2 passing through the interior of the bearing 4, and the outer end of the rotor of the first motor 2 connected to the corresponding position on the outside of the transmission frame 5. A second motor 7 is installed at the lower part of the transmission frame 5. The rotor of the second motor 7 passes through the corresponding position of the transmission frame 5. The top of the rotor of the second motor 7 is coaxially connected to the tooling table 6. The upper surface of the tooling table 6 is connected to both sides of the hinge frame 9, the inner side of the hinge frame 9 is hinged to the assembly seat 10, and the top of the assembly seat 10 is equipped with a clamping plate 11. A bracket 13 is mounted on the upper surface of the tooling table 6. A third motor 14 is mounted on the outside of the bracket 13. The rotor of the third motor 14 is coaxially connected to a drive component 15. A transmission rod 12 is inserted inside the assembly base 10. The inside of the assembly base 10 is connected to the inner end of the transmission rod 12 through a rotating shaft. The outer side of the drive component 15 is inclined. The outer end of the transmission rod 12 is connected to the inclined position of the drive component 15. A damping shock absorber ring is provided between the bearing 4 and the mounting base 3. The damping shock absorber ring is composed of two metal rings, an inner and an outer layer, and a silicone shock absorber layer sandwiched between them. The first motor 2 drives the transmission frame 5 to rotate, thereby adjusting the tooling table 6 to make left and right angle adjustments. At the same time, the second motor 7 drives the tooling table 6 to rotate circumferentially, and the third motor 14 drives the drive component 15 and the transmission rod 12 to rotate, thereby driving the assembly base 10 and the clamping plate 11 to swing back and forth. This allows the plastic-metal composite parts to be evenly contacted with the coating medium on all surfaces, avoiding the local coating omission problem common in traditional fixed tooling. This ensures that a complete coating layer is formed at key parts such as the connection between plastic and metal. The left and right tilt adjustment driven by the first motor 2 can adapt to irregular structures such as workpiece protrusions and grooves, so that difficult-to-coat areas are fully covered with film. The clamping plate 11 driven by the third motor 14 swings back and forth, further covering the deep cavity, corners and other easily overlooked parts of the workpiece, solving the problem of uneven coating, improving the wear resistance and corrosion resistance of the product, reducing rework caused by coating defects, and improving the quality of tooling. The bottom of the second motor 7 is connected to a base rod 8. The upper surface of the base plate 1 is equipped with a mounting plate 16 at a position corresponding to the base rod 8. The top of the mounting plate 16 is provided with an arc frame 17. The top of the arc frame 17 is equipped with a guide rail 18. The bottom of the base rod 8 is hinged with a roller 19. The roller 19 is inserted into the inside of the guide rail 18. The outside of the roller 19 is covered with a rubber sleeve.

[0016] This solution uses a first motor 2 to drive the rotation of the transmission frame 5, thereby adjusting the angle of the tooling table 6 in the left and right directions. Simultaneously, a second motor 7 drives the circumferential rotation of the tooling table 6, and a third motor 14 drives the rotation of the drive component 15 and the transmission rod 12, causing the assembly base 10 and the clamping plate 11 to reciprocate. This ensures that all surfaces of the plastic-metal composite parts are evenly contacted with the coating medium, avoiding the localized coating omissions common in traditional fixed tooling. It ensures that a complete coating layer is formed at critical areas such as the connection between the plastic and the metal. The left and right tilt adjustment driven by the first motor 2 can adapt to irregular structures such as protrusions and grooves on the workpiece, ensuring full coating coverage in difficult-to-plate areas. Simultaneously, the reciprocating back-and-forth swing of the clamping plate 11 driven by the third motor 14 further covers easily overlooked areas such as deep cavities and corners of the workpiece, solving the problem of uneven coating, improving the product's wear resistance and corrosion resistance, reducing rework caused by coating defects, and improving the quality of the tooling.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
