Description

Technical Field

[0001] This invention belongs to the technical field, and in particular relates to a clamping structure for a three-layer composite contact riveting machine. Background Technology

[0002] In electrical components, contacts are common structural parts. Their structural feature is that the contacts are assembled in pre-drilled holes in the coil and then fixed to the coil by riveting. These types of parts are characterized by their wide range of applications and large quantity, while the size of the contacts is very small. For a long time, the assembly operation between the contacts and the coil has been completed by a combination of working mechanisms and a lot of manual labor.

[0003] Contact riveting machines are an important production machine in modern factories. They have many advantages such as high working speed, high efficiency, simple operation, simple maintenance, and high output. However, as people's requirements are getting higher and higher, production requirements are also getting higher and higher, and environmental protection requirements are also becoming more and more important.

[0004] The common assembly method involves using an existing press with a mold for feeding, with both loading and unloading done manually. A major challenge is aligning the contacts with the pre-drilled holes on the coil. Although the mold provides guidance, manual alignment is still necessary. The small size of the contacts further complicates the process, resulting in lengthy operation times for each riveting process. This leads to extremely low productivity, high labor intensity, and increased operating costs. Furthermore, the constant manual operation during press operation poses a significant safety hazard and increases the risk of personal injury. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping structure for a three-layer composite contact riveting machine. The clamping panel is equipped with a lead screw motor and other transmission components to facilitate the adjustment of the distance between two clamping plates installed opposite each other on the clamping panel, so as to meet the clamping of metal guide plates of different sizes. This solves the problem that existing processing equipment can only process parts of one size. In addition, the installed limiting plate changes with the size of the clamping plates to meet different usage requirements.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a clamping structure for a three-layer composite contact riveting machine, comprising a mounting base with a base plate fixed thereon. Two vertical columns are positioned near one side of the base plate, and a machine head is fixed to each column. A punching head is located on one side of the machine head. A clamping seat is mounted below the punching head. One side of the clamping seat has a mounting groove, and the upper side of the clamping seat has a stepped surface structure. A clamping panel and a limiting plate are mounted on the stepped surface. The clamping panel is positioned lower than the limiting plate. The bottom surface of the clamping panel is provided with a mounting groove for installation. The positioning block has a telescopic rod installed in the mounting groove, the telescopic end of which is fixed to one side of the positioning block. The telescopic rod drives the clamping panel to move up and down. The clamping panel has a sliding groove, in which a lead screw is rotatably installed. The input end of the lead screw is installed in conjunction with the output end of the motor. Two clamping plates are symmetrically installed on the clamping panel. Both clamping plates are provided with sliders that are installed in the sliding groove. The sliders are provided with screw holes that are installed in conjunction with the lead screw. Two limiting plates are slidably installed on the step surface. The opposite sides of the two limiting plates are provided with locking slots.

[0008] Furthermore, the bottom surface of the mounting base is evenly distributed with four support legs, the length of which varies from 5cm to 10cm.

[0009] Furthermore, mounting holes are provided on both sides of the clamping seat; a mounting groove is provided on the base plate, and mounting bolts provided in the mounting groove pass through the mounting holes provided on the clamping seat to fix the clamping seat to the base plate.

[0010] Furthermore, the bottom surface of the clamping panel is symmetrically provided with two sets of guide posts, which are fitted into guide holes opened on the step surface.

[0011] Furthermore, the two clamping plates are provided with limiting grooves on opposite sides, and the internal threads of the sliders on the bottom surfaces of the two clamping plates are rotated in opposite directions.

[0012] Furthermore, the slider on the bottom surface of the limiting plate is fitted with a groove on the step surface, and a lead screw is rotatably installed in the groove that fits with the screw hole on the slider. The lead screw is driven to rotate by a motor.

[0013] Furthermore, a punching hole is provided between the slots of the two limiting plates, and the punching hole is located directly below the punching head.

[0014] The present invention has the following beneficial effects:

[0015] This invention allows for easy adjustment of the distance between two clamping plates mounted opposite each other on the clamping panel by installing transmission components such as a lead screw motor on the clamping panel, which can meet the clamping of metal guide plates of different sizes. This solves the problem that existing processing equipment can only process parts of one size. In addition, the installed limiting plate changes with the size of the clamping plates to meet different usage requirements.
