Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fastener bolt thread processing technology, specifically relating to processing equipment for fastener bolts that can produce various threads. Background Technology
[0002] In the field of fastener and bolt manufacturing, thread processing is a crucial step. With industrial development, the demand for bolt thread styles is becoming increasingly diversified, including different pitches and tooth profiles.
[0003] When faced with the need to process various thread patterns, it is necessary to frequently change various tapping heads. For example, when switching from processing ordinary triangular threads to trapezoidal threads, it is necessary to change to a specific tapping head that matches it. This process is not only cumbersome, but also requires the operator to stop the machine, carefully disassemble the original head, accurately install the new head, and perform debugging and calibration to ensure that the head position, angle and other parameters are accurate. The whole process is time-consuming and labor-intensive.
[0004] Therefore, for the existing thread processing devices for fasteners and bolts, which require the replacement of multiple tapping heads when processing various thread patterns, resulting in cumbersome tool changes and low processing efficiency for single thread tapping processing, it is possible to design a processing device for fasteners and bolts that can produce multiple threads. Utility Model Content
[0005] To overcome the problem that existing fastener and bolt thread processing devices require the replacement of multiple tapping heads when processing various thread patterns, resulting in cumbersome tool changes and low processing efficiency for single thread tapping processing.
[0006] The technical solution of this utility model is as follows: a processing equipment for fastener bolts that can produce various threads, including a processing table assembly, a tapping assembly, and a rotary clamping assembly; the rotary clamping assembly is provided at the upper end of the processing table assembly; the tapping assembly is provided in front of the rotary clamping assembly; the processing table assembly includes a processing table, a slide rail, a slide, and a feed adjustment hydraulic press; the tapping assembly includes a guide rail, a lead screw shaft, a lead screw adjustment slider, and a tapping cutter.
[0007] Preferably, the function of quick tapping tool replacement is achieved by changing the lead screw adjusting slider with different tapping tools. After changing the lead screw adjusting slider with different types of tapping tools, different thread processing functions can be realized. This solves the problem of existing fastener bolt thread processing devices, which require the replacement of multiple tapping heads when processing multiple thread patterns, resulting in cumbersome tool replacement and low processing efficiency for single thread tapping processing.
[0008] Preferably, a guide rail is provided on the top of the processing table assembly, and the outer shell of the guide rail is bolted to the processing table assembly.
[0009] Preferably, the guide rail is equipped with a lead screw adjusting slider inside, and there are two sets of lead screw adjusting sliders, which are slidably connected along the guide rail.
[0010] Preferably, the guide rail is equipped with a lead screw shaft inside, and the guide rail is connected to the lead screw adjusting slider by a lead screw thread transmission.
[0011] Preferably, the two lead screw adjusting sliders are arranged in opposite directions, and the lead screw shaft drives the lead screw adjusting sliders to move relative to each other; a tapping tool is provided on the inner side of the lead screw adjusting slider, and the tapping tool is fixedly connected to the lead screw adjusting slider.
[0012] Preferably, the upper end of the processing table is provided with a slide rail, and the outer shell of the slide rail is fixedly connected to the processing table; a slide frame is sleeved on the outer side of the slide rail, and the slide frame is slidably connected along the track between the slide rails; a feed regulating hydraulic press is provided below the slide frame, and the telescopic cylinder of the feed regulating hydraulic press drives the slide frame to slide along the slide rail.
[0013] Preferably, the rotary clamping assembly includes a variable frequency drive motor and a three-jaw chuck; the variable frequency drive motor is fixedly installed at the upper end of the carriage; the three-jaw chuck is installed at the front end of the variable frequency drive motor, and the variable frequency drive motor drives the three-jaw chuck to rotate.
[0014] The beneficial effects of this utility model are:
[0015] 1. Existing thread processing devices for fasteners and bolts suffer from the problem of cumbersome tool changes and low processing efficiency due to the need to change multiple tapping heads when processing various thread patterns. This issue can be resolved by replacing the lead screw adjustment slider with one that carries different tapping heads, enabling rapid tool changes. By changing the lead screw adjustment slider to carry different types of tapping heads, different thread processing functions can be achieved.
[0016] 2. By setting up the machining table assembly, tapping assembly, and rotary clamping assembly, one end of the bolt workpiece is first clamped and fixed by a three-jaw chuck, while the other end is placed between two lead screw adjusting sliders. Then, rotating the lead screw shaft drives the two lead screw adjusting sliders to move relative to each other and uses the tapping tool to clamp and fix the threaded end of the workpiece. Subsequently, the variable frequency drive motor drives the three-jaw chuck to rotate the bolt workpiece. At the same time, the feed adjusting hydraulic press drives the variable frequency drive motor, the three-jaw chuck, and the workpiece as a whole to feed. During the feed and rotation process, the bolt workpiece forms threads because it is cut by the tapping tool of the lead screw adjusting slider. By changing different types of tapping tools, different thread processing operations can be achieved. Attached Figure Description

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
