Description

Technical Field

[0001] The utility model belongs to the technical field related to lathe tools, and in particular relates to a combined tool for machining special-shaped grooves of rotary valve components. Background Art

[0002] The rotary valve assembly is a common industrial valve, mainly used for regulation, shutoff and flow regulation. It is usually composed of a valve body, a valve seat, a sleeve, a rotary rod and a transmission mechanism. The valve body is usually made of cast iron or steel and is used to accommodate the various components of the valve. The valve seat is usually made of stainless steel or other corrosion-resistant materials. It is used to support the valve sleeve and provide a sealing function for the rotary valve. The sleeve is the core component of the rotary valve, usually made of copper and has an orifice to allow fluid to pass through the valve. The rotary rod is a valve component used to rotate the sleeve to control the flow of fluid. The transmission mechanism is used to control the rotation direction and speed of the rotary rod, usually including a manual operating lever, gears, motors and hydraulic devices. During the production process of the rotary valve assembly, in order to cooperate with sealing and other work, corresponding mounting grooves need to be opened on the components on it, and they need to be turned with a tool. However, it still has the following disadvantages in actual use:

[0003] During the production of rotary valve assemblies, a large number of mounting grooves need to be opened. Different mounting grooves have different shapes. When turning on a lathe, multiple machining programs are required for turning. With multiple programs coordinating with turning, it takes a long time to complete the machining of a single workpiece, and the machining efficiency is relatively low.

[0004] During the production process of rotary valve components, turning is performed directly by a turning tool in coordination with a program. However, during the turning process, the operation of the lathe needs to be controlled by a program. During the lathe operation, if a program error occurs, dimensional errors are likely to occur, affecting the molding effect of the rotary valve component. Utility Model Content

[0005] The purpose of the utility model is to provide a combination tool for processing special-shaped grooves of rotary valve assembly products. By setting a front fixed block, a clamping block, a pressure plate and a tool handle, the problem of insufficient turning efficiency and easy generation of dimensional errors during turning in the production process of rotary valve assemblies is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a combined tool for processing special-shaped grooves of rotary valve assembly products, comprising a front fixed block, a clamping block, a pressure plate and a tool handle, a bayonet opening being provided on the top of the front fixed block, a clamping block being movably connected in the bayonet opening, a tool handle being fixed to one end of the front fixed block, a sliding baffle being fixed to the end of the front fixed block away from the tool handle, the bayonet opening being provided at the edge between the sliding baffle and the top of the front fixed block, a pressure plate being fixed on the top of the clamping block, and the pressure plate being provided above the tool handle, and when working, the clamping block is movably connected thereto through the front fixed block, the cutter head on the chimeric block is connected thereto through the clamping block, a suitable groove is milled out by the cutter head, and the front fixed block and the clamping block are locked together by the pressure plate in cooperation with the tool handle.

[0008] Furthermore, a socket is provided on the front fixing block at the inner bottom of the bayonet, and a fitting opening is provided in the middle of the top of the sliding baffle, and the front fixing block is movably connected to the inserting block through the socket.

[0009] Furthermore, an insert block is fixed at the bottom center of the clamping block, the insert block is inserted into the socket, and a chiseling block is fixed at one end of the clamping block.

[0010] Furthermore, the engaging block is movably connected in the engaging mouth, and the side of the engaging block away from the clamping block is flush with the side of the sliding baffle away from the front fixed block. A cutter head is fixed to the upper part of the side of the engaging block away from the clamping block. When the engaging block is working, the engaging block is movably connected through the engaging mouth, and cutting operations are performed through the cutter head.

[0011] Furthermore, a movable hole 1 is provided on the top of the pressure plate at the top of the knife handle, and a movable hole 2 is provided in the pressure plate at the bottom of the movable hole 1. A fastening bolt is movably connected in both the movable hole 1 and the movable hole 2.

When the knife handle is working, the fastening bolt is installed through the mounting screw hole.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of insufficient turning efficiency in the production process of the rotary valve assembly by arranging a front fixing block, a clamping block, a pressure plate and a tool handle. The corresponding tool head is selected, and then the plug block at the bottom of the clamping block is inserted into the socket in the bayonet, and then the clamping block enters the bayonet on the front fixing block. At this time, the chimeric block enters the chimeric mouth on the sliding baffle, completing the assembly between the clamping block and the front fixing block, and then the fastening bolt is inserted into the movable hole 2 in the movable hole 1, and then screwed into the mounting screw hole on the tool handle until the bolt head of the fastening bolt enters the movable hole 1. After tightening, the front fixing block and the tool handle are combined with the clamping block and the pressure plate, so that the tool head can be replaced, and the corresponding special-shaped groove shape is directly turned. Through streamlined turning by multiple lathes, the turning efficiency is higher.

[0015] The utility model solves the problem of dimensional error easily occurring in the turning of the rotary valve component by arranging the front fixing block and the clamping block. After the clamping block and the pressure plate are installed on the tool handle and the front fixing block, the tool handle is clamped in a suitable position on the machine tool, and the machine tool can be started to work. When the tool is fed in, the tool head contacts the rotary valve workpiece, and a groove is turned out on the rotary valve workpiece. During the feeding process, the rotary valve workpiece is continuously cut until the position where the rotary valve workpiece does not need to be cut contacts the engaging block and the sliding baffle, and it is determined that the cutting of the rotary valve workpiece is completed. After completion, the tool is withdrawn by the machine tool to complete the grooving of the rotary valve workpiece, so that the dimensional error in the turning of the rotary valve component is smaller.
