Description

Technical Field

[0001] This utility model relates to the field of tooling and fixtures, specifically to a positioning tooling for multi-face drilling of valve bodies. Background Technology

[0002] The valve body is the core load-bearing component of a hydraulic valve and the physical basis for realizing the fluid control function of a hydraulic system. Internally, it has multiple precision channels for the flow and distribution of hydraulic oil. Externally, it connects to other hydraulic components (such as pipelines, pumps, and actuators) or equipment frames through mounting holes, threaded interfaces, and other structures. The valve body must be made of high-strength, corrosion-resistant metal materials (such as cast iron and aluminum alloys), and precision machining must ensure the accuracy and sealing of the channels. Its structure directly determines the core functions of hydraulic oil flow control, including on / off switching, flow direction switching, pressure regulation, and flow control. It is a crucial carrier for ensuring the stable operation of hydraulic system (such as construction machinery and industrial automation equipment) actuators according to predetermined actions.

[0003] The structure of hydraulic valve bodies is often not regular, such as... Figure 3 , Figure 4 The hydraulic valve body shown has protrusions or grooves on its surface, and its bottom is fixedly connected to multiple mounting brackets with mounting holes for connection to other equipment frames. Multiple surfaces of the hydraulic valve require drilling, but existing positioning fixtures are insufficient to limit and fix the irregular valve body without affecting the drilling process. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a positioning fixture for multi-face drilling of valve body, which aims to solve the problem that existing positioning fixtures are difficult to limit and fix the valve body without affecting the drilling process.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A positioning fixture for multi-face drilling of valve bodies includes a base plate with a support column at its center. The upper end of the support column has a platform for supporting the valve body to be drilled. A pressure sensor is located on the side of the support column facing the platform. Hydraulic lifting rods are provided on the upper side of the base plate at positions corresponding to the mounting holes of the valve body mounting bracket. The hydraulic lifting rods are perpendicular to the base plate, and their telescopic ends slide in engagement with the mounting holes of the mounting brackets. A detachable stop block is fixedly connected to the telescopic end of the hydraulic lifting rod extending out of the mounting hole.

[0007] Furthermore, each of the abutments is fixedly connected to a vertical rod on its upper side, and each of the vertical rods is slidably connected to an L-shaped limiting block. The limiting block is detachably connected to the vertical rod by bolts, and the limiting block is used to limit and fix the upper edge of the valve body to be processed.

[0008] Furthermore, the contact surfaces of the limiting block and the valve body to be processed are both provided with rubber pads.

[0009] This structural design allows the limiting block to make full contact with the valve body to be processed through the rubber pad, resulting in better limiting effect and avoiding damage to the valve body.

[0010] Furthermore, the abutment block is threadedly connected to the telescopic end of the hydraulic lifting rod.

[0011] Furthermore, the stop block is inserted into the telescopic end of the hydraulic lifting rod, and the stop block is detachably connected to the hydraulic lifting rod by means of bolts.

[0012] Furthermore, through holes are provided at each of the four corners of the base plate.

[0013] This structural design makes it easy to install and fix the base plate.

[0014] Beneficial effects:

[0015] This utility model discloses a positioning fixture for multi-face drilling of valve bodies, which includes a base plate, support column, platform, hydraulic lifting rod, stop block, vertical rod and limiting block. It can not only stably clamp and fix the valve body to be processed, but also leave sufficient operating space while fixing it so as to drill holes on various surfaces of the valve body to be processed. It is easy to operate and has high processing efficiency. Attached Figure Description

[0023] like Figure 1 and Figure 2 As shown, this utility model discloses a positioning fixture for multi-faceted drilling of valve bodies, comprising a base plate 1. Through holes are provided at each of the four corners of the base plate 1. A support column 2 is fixedly connected to the center of the base plate 1. A platform 3 for supporting the valve body to be processed is installed on the upper end of the support column 2. A pressure sensor is installed on the side of the support column 2 facing the platform 3. The pressure sensor is used to detect the pressure applied to the valve body to be processed by the positioning fixture in real time, preventing damage to the valve body. Hydraulic lifting rods 4 are installed on the upper side of the base plate 1 at positions corresponding to the mounting holes of the valve body mounting bracket. The hydraulic lifting rods 4 and the support columns 2 are perpendicular to the base plate 1. The telescopic end of the hydraulic lifting rod 4 slides in conjunction with the mounting hole of the mounting bracket. A detachable stop block 5 is fixedly connected to the telescopic end of the hydraulic lifting rod 4 extending out of the mounting hole. The valve body to be processed in this embodiment is as follows: Figure 3 and Figure 4 As shown.

[0024] As a preferred embodiment, each of the abutment blocks 5 is fixedly connected to a vertical rod 6, and each of the vertical rods 6 is slidably connected to an L-shaped limiting block 7. The limiting block 7 is detachably connected to the vertical rod 6 by bolts, and the limiting block 7 is used to limit and fix the upper edge of the valve body to be processed.

[0025] As a preferred embodiment, the contact surfaces of the limiting block 7 and the valve body to be processed are provided with rubber pads.

[0026] As a preferred embodiment, the abutment 5 is inserted into the telescopic end of the hydraulic lifting rod 4, and the abutment 5 is detachably connected to the hydraulic lifting rod 4 by means of bolts.

[0027] When drilling holes in the valve body to be machined, the positioning fixture of this utility model must first be used to fix the valve body to be machined. The specific operation is as follows:

[0028] First, place the valve body to be processed on the carrier plate, which supports the center of the bottom of the valve body. Then, adjust the position of the valve body so that the mounting hole on the side mounting bracket of the valve body is aligned with the free end of the corresponding hydraulic lifting rod 4. The positioning fixture of this invention is specifically designed for the valve body to be processed. After the position is aligned, adjust the height of the hydraulic lifting rod 4 so that the free end of the hydraulic lifting rod 4 extends out of the corresponding mounting hole. Then, fix the abutment block 5 with the vertical rod 6 to the free end of the hydraulic lifting rod 4 with bolts. Then, adjust the hydraulic lifting rod 4 to retract until the abutment block 5 presses down and abuts the mounting bracket of the valve body. Then, place the limiting block 7 on the vertical rod 6 and fix the limiting block 7 with bolts. The limiting block 7 just limits the upper edge of the valve body, assisting in positioning and fixing.

[0029] The positioning fixture of this utility model can not only stably clamp and fix the valve body to be processed, but also leave sufficient operating space while fixing it so as to drill holes on various surfaces of the valve body to be processed.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
