Description

Technical Field

[0001] The utility model relates to the technical field of valve cover drilling, in particular to the field of drilling tooling, and specifically refers to a valve cover drilling jig tooling. Background Art

[0002] The valve cover is a valve part equipped with a valve stem seal, which is used to connect or support the actuator. The valve cover and the valve body can be an integral whole or separated. The valve cover in the gate valve mainly plays the role of compressing the packing. The valve cover positions the valve stem to ensure that the valve stem can normally transmit the switch and seal the valve. It has a certain strength to prevent the internal fluid from flowing out. The drilling device refers to the general term for equipment used to process holes in solid materials. Common drilling devices include electric drills and drilling machines. With the further development of processing technology, the efficiency of drilling devices has also been greatly improved. The drilling machine refers to a machine tool that mainly uses a drill to process holes on the workpiece. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. It can replace special tools, expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, the center of the tool is aligned with the center of the hole, and the tool rotates. The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. The application range of drilling processing equipment is very wide, and it also plays a very important role in valve cover production.

[0003] The valve cover needs to be clamped by a workpiece during the drilling process. The valve cover processing tooling needs to stably clamp the valve cover while keeping the drilling position of the valve cover coaxial with the drill sleeve. The existing tooling has cumbersome positioning, the clamping is not tight enough, and the round valve cover is prone to rotation. Utility Model Content

[0006] The utility model provides a body for installing a valve cover, a support frame for supporting the valve cover and a drill sleeve, and a pressing piece for pressing the valve cover. The left end of the valve cover is the pressing piece, and the pressing piece presses the valve cover onto the support frame at the right end. A drill bit is installed on the drill sleeve to drill a hole in the valve cover. A positioning block can position the valve cover. The positioning block is located at the rear of the valve cover and can position the front and rear positions of the valve cover. After the pressing piece presses the valve cover, the left and right positions of the valve cover can be positioned, so that the drill hole of the valve cover is coaxial with the drill sleeve.

[0007] As an optimization, a bottom groove is provided on the upper end surface of the machine body, and the bottom groove is coaxially arranged with the drill sleeve.

[0008] As an optimization, the positioning block includes a vertical block and two horizontal blocks, the two horizontal blocks are respectively fixed to the upper and lower ends of the vertical block, and the two horizontal blocks extend horizontally to the upper and lower protrusions of the valve cover. The setting of this optimization scheme can limit the upper and lower ends of the valve cover to prevent the valve cover from tilting and ensure that the upper and lower ends of the valve cover are coaxially arranged with the drill sleeve.

[0009] As an optimization, the clamping member includes a bolt rod and a loose block, the bolt rod is threadedly connected to the machine body along the left-right direction, and the loose block is fixed to the right end of the bolt rod. According to the setting of this optimization scheme, the bolt rod can be rotated to make the loose block press the valve cover, and the loose block can reduce the wear of the tooling on the workpiece during the clamping process of the valve cover.

[0010] As an optimization, a mounting frame is fixedly connected to the machine body, and the bolt rod is threadedly connected to the mounting frame. The arrangement of this optimization scheme facilitates the installation of the clamping member and facilitates the rotation of the bolt rod to clamp the valve cover.

[0011] As an optimization, the support frame includes a horizontal plate and a vertical plate, the horizontal plate is fixed to the upper end of the vertical plate, the right end of the valve cover is pressed against the vertical plate, the horizontal plate is located above the valve cover, and a mounting hole extending up and down is opened on the horizontal plate, and the drill sleeve is placed in the mounting hole. In the setting of this optimization scheme, the vertical plate can block the valve cover, and the horizontal plate can be used to install the drill sleeve so that the drill sleeve is located above the valve cover.

[0012] As an optimization, the left end of the bolt rod is fixedly connected with a bolt head, and a turning handle hole is opened on the bolt head. The setting of this optimization scheme facilitates the valve cover to be compressed and clamped by inserting the turning rod into the turning handle hole and twisting the bolt rod.

[0013] The beneficial effects of the utility model are as follows: the utility model clamps the valve cover by arranging a clamping piece, and at the same time, the bolt rod of the clamping piece is threadedly connected to the mounting frame, which is convenient for the left and right movement of the clamping piece, and the movable block of the clamping piece is threadedly connected to the bolt rod, which is convenient for removing the ring of the movable block; the bottom groove can initially limit the valve cover, and the limit block can position the valve cover, so that the drill hole of the valve cover is coaxial with the drill sleeve, thereby making the drilling of the valve cover more accurate.
