Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping fixture technology, specifically to a fixture for drilling and tapping equipment. Background Technology

[0002] With the continuous development of science, the use of bushings, washers, and other parts is increasing, including in various aspects of the aerospace field, such as aerospace vehicle components, missile components, and ship components. Bushings and washers are special parts; they are used in large quantities, come in various shapes, require high precision, are difficult to process, and are prone to failure. Therefore, their manufacturing and processing have always been a critical link for various production and processing enterprises. During the drilling and tapping process, washers require the use of fixtures to assist in fixing the drive shaft to facilitate drilling.

[0003] For example, a gasket drilling and tapping fixture with publication number "CN220330541U" includes a threaded sleeve and a machining sleeve. The machining sleeve includes a fixed seat and a clamping seat, which are coaxially connected. The clamping seat is divided into an upper tube, a middle tube, and a lower tube, and the clamping seat is connected to the fixed seat through the lower tube. The middle tube has a larger diameter than the upper tube and is threaded on its side wall. A blind hole is opened at the top of the upper tube, and the blind hole extends downward into the middle tube. The threaded sleeve includes a sleeve and a top cover. The top cover is located at the top of the sleeve, and the upper tube and the middle tube can be inserted into the sleeve. The inner wall of the sleeve is provided with an internal thread that matches the thread of the middle tube, and a machining hole is opened in the middle of the top cover.

[0004] However, in the above documents, the blind hole length is fixed, and the number of washers is entirely determined by the blind hole length. It is impossible to flexibly adjust the number of washers according to processing requirements (such as batch size and drill stroke), resulting in insufficient versatility. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a drilling and tapping jig that can improve versatility, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clamp for a drilling and tapping equipment, comprising a threaded sleeve and a machining sleeve threadedly connected to the threaded sleeve, characterized in that: the machining sleeve comprises a fixed base, the upper end face of the fixed base is provided with an installation part, at least one set of sub-sleeves are detachably provided on the installation part, the sub-sleeves are provided with a first blind hole, the upper end of the sub-sleeves is detachably provided with a female sleeve, and the female sleeve is provided with a second blind hole communicating with the first blind hole.

[0007] The above technical solution is adopted in contrast to the existing technology which cannot flexibly adjust the number of clamping rings according to processing requirements (such as batch size and drill bit stroke). This utility model is composed of multiple detachable sub-sleeves, and the total length of the blind hole can be adjusted by increasing or decreasing the number of sub-sleeves, thereby flexibly controlling the number of washers clamped.

[0008] A further feature of this invention is that the outer wall of the female sleeve is provided with a threaded portion, the diameter of which is greater than the diameter of the male sleeve and the female sleeve. The inner wall of the threaded sleeve is provided with an internal thread that matches the threaded portion, and a machining hole is provided in the middle of the top of the threaded sleeve. The top of the female sleeve is tapered inward into a conical shape.

[0009] The above technical solution facilitates the installation of the threaded part onto the female sleeve. Simultaneously, the machining hole allows the threaded part to be installed onto the female sleeve after the washer is placed into the blind hole. By installing this invention into a drilling and tapping device, and then inserting a drill bit through the machining hole, the washer can be drilled and tapped.

[0010] A further feature of this invention is that: a first mounting block is provided on each of the opposite sides of the mounting part, and a second mounting block corresponding to the first mounting block is provided on the outer wall of the end of the sub-sleeve near the mounting part, and the first mounting block and the second mounting block are connected by fasteners.

[0011] The above technical solution allows for simple assembly during installation. Simply align the mounting part with the sub-sleeve, align the first mounting block and the second mounting block, and then insert the fasteners. The structure is simple and the assembly is convenient.

[0012] A further feature of this invention is that a third mounting block is provided on the outer wall of the end of the sub-sleeve away from the mounting part, and a fourth mounting block corresponding to the third mounting block is provided on the lower end face of the female sleeve. The third mounting block and the fourth mounting block are connected by fasteners.

[0013] Using the above technical solution: During the installation process, simply align the sub-sleeve with the female sleeve, align the third mounting block and the fourth mounting block, and then insert the fasteners to complete the assembly. The structure is simple and the assembly is convenient.

[0014] A further feature of this invention is that a first positioning groove is provided on the upper end face of the mounting part, and a first positioning block is provided on the end face of the sub-sleeve near the mounting part, which is inserted into the first positioning groove.

[0015] The above technical solution facilitates the assembly of the fixed seat and the sub-sleeve by setting the first positioning groove and the first positioning block, achieving the positioning effect and making assembly easier.

[0016] A further feature of this invention is that the end of the sub-sleeve furthest from the mounting portion is provided with a second positioning groove, and the lower end of the female sleeve is provided with a second positioning block that can be inserted into the second positioning groove.

[0017] The above technical solution is adopted: by setting the second positioning groove and the second positioning block, the female sleeve and the female sleeve can be positioned during assembly to prevent positional deviation and ensure that the female sleeve and the female sleeve are coaxial. At the same time, when the number of female sleeves needs to be increased to adjust the total length of the blind hole according to the processing requirements, the second positioning groove can cooperate with the first positioning block on another female sleeve for positioning and installation.

[0018] A further feature of this invention is that the bottom end of the fixing base has an installation hole.

[0019] The above technical solution allows for easy fixing of the assembled fixture onto the drilling and tapping equipment via mounting holes, facilitating assembly by workers.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
