Description

Technical Field

[0001] This utility model relates to a cutting fixture for the coating material inside a housing, and more particularly to an automatic cutting fixture for the coating material inside a housing. Background Technology

[0002] Currently, existing high-temperature and high-pressure cylindrical shells require pre-reserved installation ports for mounting components. The interior of these shells is coated with a heat insulation layer. However, due to the low density and weak support of this layer, the sealing strength of the mounting components at the installation port is poor. The inner edge of the installation port is covered by the heat insulation layer, which needs to be cut. The cut insulation layer is then used to create coating holes. Since these holes are typically cut manually, the edges require repeated trimming and cutting, resulting in burrs around the manually cut holes. Furthermore, the manually cut coating holes have significant errors compared to the mounting components, affecting the sealing performance of the internal components. Therefore, this paper proposes an automatic cutting fixture for the coating layer inside the shell. Utility Model Content

[0003] The purpose of this invention is to overcome the challenges of reserving installation openings on high-temperature and high-pressure cylindrical shells, where the density of the heat insulation layer sprayed on the shell is low, resulting in weak support strength. The inner edge of the installation opening, where the heat insulation layer is sprayed, needs to be cut, leaving a coating hole. Since cutting these holes is typically done manually, the edges require repeated trimming and cutting, resulting in burrs around the manually trimmed holes. Furthermore, the manually cut coating holes have significant errors compared to the installation components of the shell, affecting the sealing performance of the internal components. This invention provides an automatic cutting fixture for the coating layer inside the shell, specifically a coating hole positioning fixture. After the control center is activated, it positions itself using the cylindrical shell's axis marker. The positioning probe detects the corresponding cutting positioning mark, and then the hydraulic cylinder lever moves upward to cut the component hole, reducing errors and eliminating burrs. It eliminates the need for manual trimming and cutting of the coating hole edges, improving the accuracy of the installation components and the sealing performance of the internal components of the cylindrical shell.

[0005] The machine base has a pair of guide rails on both sides at the upper end. Two pairs of transverse sliding seats are arranged horizontally on the guide rails. The two pairs of transverse sliding seats are respectively a pair of first transverse sliding seats and a pair of second transverse sliding seats. The first transverse sliding seats and the second transverse sliding seats are respectively provided with active sliders between them and the guide rails on one side. A transverse sliding screw is provided on one side of the first transverse sliding seat and the second transverse sliding seat. A lifting seat is provided on the second transverse sliding seat. A pair of lifting screws are provided between the two ends of the lifting seat and the second transverse sliding seat. A pair of cylinder rotating devices are provided on the first transverse sliding seat and the lifting seat. A pair of rotating limit seats are respectively provided in the middle part of the cylinder rotating devices. A pair of active rollers are provided at the bottom two ends of the rotating guide groove of the rotating limit seat of the first transverse sliding seat. A cylinder rotating device is provided above the pair of active rollers. A pair of driven rollers are provided at the bottom two ends of the rotating guide groove of the rotating limit seat of the lifting seat. A cylinder rotating device is provided above the pair of driven rollers.

[0006] A pair of cylindrical rotating devices are configured with a pair of coaxially rotating annular cavities in the middle. Telescopic positioning keys are evenly distributed on the inner side of the pair of cylindrical rotating devices. A cylindrical shell is set in the pair of cylindrical rotating devices. Different parts of the cylindrical shell wall are reserved with first component holes, second component holes, and third component holes respectively corresponding to the shape of the installation components. The inner side of the cylindrical shell is sprayed with a cylindrical inner coating. Positioning stickers are attached to the inner edge of the cylindrical inner coating of the first component holes, second component holes, and third component holes. A cutting positioning mark is set on one side of the positioning sticker. An axis mark is set at the center of the cutting positioning mark at one end of the cylindrical shell. A pair of rotating limit seats are reserved with rotating grooves. Two pairs of guide pins are set at the upper part of both ends of the rotating limit seats. Rotating guide grooves are reserved on both sides of the pair of cylindrical rotating devices. Guide pins are set in the rotating guide grooves on both sides of the cylindrical rotating devices.

[0007] A pair of cutting frames are installed at both ends of the machine base. The pair of cutting frames are configured as a pair of A-frames. A cutting guide rail is installed at the top of the pair of cutting frames. A guide slider is installed above the cutting guide rail. A hydraulic cylinder is installed above the guide slider. A pressure pipe is installed between the hydraulic cylinder and the hydraulic pump. A hydraulic lever is installed above the hydraulic cylinder. A cutting blade is installed at the top of the hydraulic lever. A cutting plate is installed at the bottom of the cutting blade. A cutting blade edge is vertically installed on the upper edge of the cutting plate. A cutting blade positioning pin is installed on one side of the center of the lower part of the cutting plate. A cutting blade positioning groove is reserved at the upper end of the hydraulic lever. A cutting blade positioning pin is installed in the cutting blade positioning groove. A positioning probe is installed on one side of the hydraulic cylinder. A sensor circuit for the probe signal is installed between the positioning probe and the control center. A slider control circuit is installed between the control center and the guide slider. The positioning probe is positioned corresponding to the center of the cutting positioning mark. A sensor circuit is installed between the control center and the positioning probe. The control center is equipped with an alert light and a horn. The control center can be set to automatic mode or manual mode.

[0008] Workflow: When cutting the inner coating of the cylinder inside the holes of the first component, the second component, and the third component, the cutting guide rail is manually slid to the cutting frame at one end. After the cutting guide rail leaves the cutting frame at the other end, the cylindrical shell is manually controlled to be installed into a pair of annular cavities by a pair of corresponding cylindrical rotating devices. After the cylindrical shell is manually checked to be installed in place, it is locked by telescopic positioning key to complete the installation of the cylindrical shell.

[0009] After the cylindrical shell is installed, the cutting guide rail and the cutting frame at the other end are manually restored to their original positions and fixed. After the cutting guide rail is fixed in its original position, the automatic mode of the control center is manually activated. The cylindrical shell is rotated by the active roller. When the cylindrical shell rotates to the axis mark of the cutting positioning mark corresponding to the first component hole of the positioning probe, the control center will remind the user with lights and a horn and stop the rotation, thus completing the positioning of the axis mark of the cylindrical shell.

[0010] After the axis mark of the cylindrical shell is positioned, the guide slider is manually activated through the control center to drive the hydraulic cylinder and positioning probe to move into the cylindrical shell. When the positioning probe detects the center of the cutting positioning mark, the guide slider automatically stops. After the guide slider stops automatically, the control center automatically starts the lever of the hydraulic cylinder to move upward. When the cutting blade cuts into the coating inside the cylindrical shell and encounters resistance, the control center automatically stops the upward movement of the hydraulic cylinder lever, thus completing the cutting of the first component hole.

[0011] After the first component hole is cut, the hydraulic cylinder lever automatically stops running, and the control center automatically starts the hydraulic cylinder lever to drive the cutting blade downward. After the cutting blade detaches from the coating inside the cylinder, the control center automatically starts the guide slider to return to the inlet of the cylindrical shell. The waste material of the coating inside the cylinder of the cutting blade is cleaned manually. The cutting blade of the first component hole is removed manually, and the cutting blade of the second component hole is installed. The second component hole and the third component hole are cut according to the above procedures.

[0012] Beneficial effects: This utility model is a spray coating cutting fixture for positioning coating holes; after the control center is turned on, the control center is positioned by the axis mark of the cylindrical shell. After the positioning probe detects the cutting positioning mark and positions it, the upward movement of the hydraulic cylinder lever cuts the component hole, reducing the error of the cut component hole and eliminating burrs; it eliminates the need for manual cutting and trimming of the coating hole edge, which can improve the accuracy of the installed components and the sealing of the components installed inside the cylindrical shell.
