Description

Technical Field

[0001] This utility model relates to the field of precision boring tool technology, specifically a precision boring tool for housings. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. Based on the processing method, it can be divided into cutting machining and pressure machining. Cutting machining is generally performed using boring tools. A boring bar is a type of boring tool, typically with a round shank, although square shanks are sometimes used for larger workpieces. Its most common applications are internal hole machining, reaming, and contouring. A boring bar is a tool with one or two cutting parts specifically designed for roughing, semi-finishing, or finishing existing holes. Boring bars can be used on boring machines, lathes, or milling machines. Fine boring tools are required when drilling holes in housings.

[0003] Currently, existing precision boring tools require the tool head to be replaced when different hole diameters are needed. However, existing tool heads are basically fixed with screws, resulting in low efficiency during disassembly and replacement. Therefore, a precision boring tool for housings is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a precision boring tool for housings, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a precision boring tool for a box body, including a tool holder, a tool head inserted inside the tool holder, a fixed seat mounted on the tool holder, an insert block provided on the fixed seat, a guide rod fixedly installed at the bottom of the insert block, and a spring sleeved on the guide rod;

[0006] The tool holder has a limiting groove inside, a limiting post is provided inside the limiting groove, an insert is fixedly connected to the limiting post, a positioning seat is fixedly installed on the limiting post, a positioning hole is provided on the positioning seat, and the insert is inserted into the positioning hole.

[0007] A fixing block is fixedly connected to the cutting head, and a fixing hole is opened on the fixing block, through which the insertion post passes.

[0008] Preferably, a pull block is fixedly installed on the positioning seat, which allows the operator to easily pull the insertion post out of the fixing hole on the fixing block.

[0009] Preferably, the bottom of the fixing base has a through hole, the guide rod passes through the inside of the through hole, and a pressure plate is fixedly connected to the insertion block. The pressure plate allows the operator to press the pressure plate to move the insertion block downwards.

[0010] Preferably, the upper end of the spring abuts against the bottom of the insert block, and the lower end of the spring abuts against the inner wall of the fixing seat. The spring arrangement allows the insert block to be inserted into the positioning hole under the force of the spring.

[0011] Preferably, two positioning strips are fixedly connected to the inner wall of the tool holder. The two positioning strips are fixedly connected to the inner front wall and inner rear wall of the tool holder, respectively. The positioning strips can be used to position the tool head, thereby facilitating the insertion of the tool head into the interior of the tool holder.

[0012] Preferably, the cutter head is provided with a positioning groove, and the positioning strip is inserted into the inside of the positioning groove. The positioning groove and the positioning strip can limit the position of the cutter head.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. When the tool head needs to be replaced, the user can press down on the pressure plate to move the insert block downwards and disengage it from the positioning hole. At this time, the user can pull the puller away from the tool holder to disengage the insert from the fixing hole on the fixing block. The tool head is then removed from the tool holder, making it easy to quickly disassemble and replace the tool head.

[0015] 2. The precision boring tool for the housing, through the setting of positioning groove and positioning strip, can limit and guide the tool head, so that after the upper end of the tool head is inserted into the tool holder, its fixing hole can be aligned with the insertion post, thereby facilitating and quickly installing and fixing the tool head, and further improving the practicality of the precision boring tool.
