Description

Technical Field

[0001] This invention relates to the field of jig processing technology, specifically to a clamping fixture for jig processing. Background Technology

[0002] A jig is a broad category of tools used in woodworking, metalworking, fitter work, mechanics, electrical control, and other handicrafts. It primarily serves to assist in controlling position or movement (or both). Jigs can be categorized into three types: process assembly jigs, project testing jigs, and circuit board testing jigs. Some types of jigs are also called "molds" or "auxiliaries." Their main purpose is to repeat and accurately reproduce certain parts, making them important tools for mass production. They were widely used before the industrial era, including mechanical jigs, woodworking jigs, welding jigs, jewelry jigs, and others. To facilitate workpiece forming, complex groove and hole structures are required on the upper part of the jig. During jig processing, machine tools are used to create these grooves and holes. To ensure the accuracy of the hole creation, clamping fixtures are used to hold and position the jig during processing.

[0003] For some jigs with symmetrical slot distribution, such as circular or square jigs, the uniform and symmetrical distribution of slots on the upper part of the jigs requires high clamping and positioning accuracy. Traditional clamping fixtures often have asymmetrical movement settings for the clamping base, which cannot effectively adjust and position the jig during the clamping process. When clamping and installing the jig, the installation position of the jig needs to be adjusted manually, which is complicated and inconvenient. Therefore, a jig clamping fixture for jig processing is proposed. Summary of the Invention

During the clamping process, the rolling guide support of the positioning guide wheel 4, combined with the symmetrical and synchronous clamping action, can quickly and accurately guide and position the fixture placed on the machining table 1. The fixture can be accurately installed and positioned without manual adjustment. Compared with traditional clamping fixtures, it has better operational convenience. The positioning guide wheel 4 is rolled and installed at the end of the telescopic support rod 5 under the push of the thrust spring 6. During the clamping process, the elastic push of the thrust spring 6 can ensure that the side of the fixture is evenly stressed. The rolling support of the positioning guide wheel 4 can ensure that the fixture moves and adjusts smoothly under the pushing force, which greatly improves the positioning accuracy of the fixture.

[0038] The drive mechanism is located at the lower part of the machining table 1. The drive mechanism is used for the sliding drive of the sliding clamp 2. The drive mechanism includes a drive motor 14, a drive screw 15, a bevel drive gear 16, and a bevel transmission gear 17. To reduce the rotational speed and increase the driving torque, as shown in the attached diagram... Figure 2 As shown, a reducer 18 is provided on the side of the drive motor 14. To facilitate the fixed installation of the reducer 18, a mounting plate 19 is fixedly installed on the upper part of the reducer 18. The mounting plate 19 is fixedly installed on the bottom center of the processing table 1 by bolts. The drive motor 14 is a servo motor and serves as the drive device of the equipment. The drive motor 14 is fixedly installed on the side of the reducer 18 by bolts. The shaft end of the drive motor 14 is fixedly connected to the input shaft end of the reducer 18. After the fixture is clamped, the reverse locking structure of the reducer 18, in conjunction with the electrical signal self-locking of the drive motor 14, can achieve stable clamping and limiting of the fixture.

[0039] The drive screw 15 serves as the transmission drive structure for the sliding clamp 2. The drive screw 15 is rotatably mounted inside the guide groove 7. For connection and installation with the drive screw 15, see attached... Figure 6As shown, a drive screw hole 20 is provided through the middle of the guide slider 8. The drive screw 15 is threadedly connected to the drive screw hole 20. In order to synchronously drive the four sets of sliding clamps 2, the conical drive gear 16 and the conical transmission gear 17 are respectively installed on the drive force transmission side of the drive motor 14 and the drive screw 15, as shown in the attached figure. Figure 7 As shown, the conical drive gear 16 is fixedly installed on the output shaft end of the reducer 18, and the conical transmission gear 17 is fixedly installed on the torque input end of the drive screw 15. The conical transmission gear 17 is meshed with the upper part of the conical drive gear 16 through the tooth groove. The transmission structure relies on the meshing transmission between the conical drive gear 16 and the conical transmission gear 17. The structure is simple and the operation is reliable. Multiple sets of sliding clamps 2 can be synchronously driven by the drive motor 14. The symmetrical moving clamp can quickly and stably clamp and fix the fixture with a symmetrical shape.

[0040] To ensure the rotational stability of the drive screw 15 by mounting support at its end, as shown in the attached figure... Figure 1 As shown, a lead screw support 9 is fixedly installed on the opening side of the guide groove 7 by bolts, and the end of the drive lead screw 15 is rotatably supported and installed on the inner side of the shaft hole provided in the middle of the lead screw support 9.

[0041] Working principle or structural principle: During operation, the sliding clamp 2 is located at the outermost side of the guide groove 7 in the maximum opening position. Taking a square fixture as an example, when loading the fixture, the fixture is initially aligned and placed in the fixture placement area on the upper part of the machining table 1. Then, the clamping and positioning steps are performed. The drive motor 14 works to input the driving force into the reducer 18. After the torque is amplified by the reducer 18, the driving force is transmitted to the conical drive gear 16. Under the rotation drive of the conical drive gear 16, the conical transmission gear 17 meshing with it rotates, causing the drive screw 15, which is in a symmetrical position, to rotate synchronously in the opposite direction. Under the drive of the drive screw 15, the four sets of sliding clamps... The sliding clamp 2 moves inward synchronously and clamps. During the movement, the positioning guide wheel 4 at the front of the sliding clamp 2 first contacts the side of the fixture. After contact, the fixture moves back to its correct position under the push of the positioning guide wheel 4, and the fixture is guided and positioned by the elastic pushing force on the periphery. Then the sliding clamp 2 continues to move until the functional clamping block 3 contacts and clamps the side of the fixture, completing the clamping and fixing operation of the fixture. After that, the slot opening of the fixture is completed by the external processing machine tool. Then the drive motor 14 is unlocked and rotated in reverse, driving the four sets of sliding clamps 2 to slide and reset, completing the release operation of the fixture. The fixture is taken out and the next set of fixtures is reloaded, completing the processing flow.

[0042] In summary, this clamping fixture adopts a symmetrical clamping structure. The transmission structure relies on the meshing of a conical drive gear 16 and a conical transmission gear 17. The structure is simple and reliable. Multiple sliding clamps 2 can be synchronously driven by a drive motor 14. Symmetrical moving clamping allows for quick and stable clamping and fixing of symmetrical fixtures. A guide wheel-type positioning auxiliary structure is provided at the front of the sliding clamp 2. The positioning guide wheel 4 is movably mounted on the front side of the sliding clamp 2 via a telescopic support rod 5. During clamping, the rolling guide support of the positioning guide wheel 4, combined with the symmetrical synchronous clamping action, allows for quick and precise guiding and positioning of the fixture placed on the machining table 1, without the need for manual adjustment. The precise installation and positioning of the fixture offers better operational convenience compared to traditional clamping fixtures. The positioning guide wheel 4 is rolled and mounted on the end of the telescopic support rod 5 under the push of the thrust spring 6. During clamping, the elastic push of the thrust spring 6 ensures uniform force on the sides of the fixture, and the rolling support of the positioning guide wheel 4 ensures smooth movement and adjustment of the fixture under the pushing force, greatly improving the positioning accuracy of the fixture. The functional clamping block 3 adopts a modular structure and is installed and connected using the clamping block mounting slot 10 and fastening bolts 11. The structure is simple and easy to disassemble and assemble. During operation, the functional clamping block 3 can be flexibly replaced according to the shape characteristics of the fixture, so that the fixture can meet the clamping requirements of different types of fixtures.
