Description

Technical Field

[0001] This utility model relates to the field of valve body machining positioning tooling, specifically to a positioning component for machining the valve body of a drilling mud pump. Background Technology

[0002] A mud pump is a machine used in drilling to deliver mud or water flushing fluid into the borehole. The valve body on the mud pump is a pipeline accessory used to open or close the pipeline, control the flow direction, and regulate and control the delivered medium. The mud pump is connected to flanges at both ends, and holes need to be drilled on the flanges. For aesthetic reasons or production requirements, the holes on the two flanges need to correspond one-to-one. Existing drilling positioning fixtures fix the valve body to facilitate drilling, but when drilling holes at both ends of the flange, it cannot be guaranteed that the holes at both ends correspond one-to-one. Utility Model Content

[0003] This utility model provides a positioning component for machining the valve body of a drilling mud pump.

[0004] The technical solution of this utility model is implemented as follows: a positioning component for machining a drilling mud pump valve body includes a fixed base plate mounted on a lathe. A placement groove for placing the valve body is opened at the center of the fixed base plate. Two vertically arranged fixing rods are symmetrically arranged on both sides of the placement groove. A clamping plate is inserted through the two fixing rods. Several positioning holes are distributed around the circumference of the clamping plate. Connecting plates are arranged on both sides of the clamping plate. The connecting plates are inserted through the fixing rods. Fixing nuts are installed on the fixing rods at the top and bottom of the clamping plate.

[0005] An insertion block is fixedly connected to the bottom of the clamping plate, and the insertion block cooperates with the valve body.

[0006] The inner circumference of the placement groove has several positioning grooves corresponding to the positioning holes.

[0007] A vertically arranged compression spring is fixedly connected inside the positioning groove, and a positioning post is fixedly connected to the top of the compression spring.

[0008] Guide posts are provided at the bottom of the positioning post and at the top of the positioning groove, and compression springs are located outside the guide posts.

[0009] The technical solution of this utility model has the following positive effects: This utility model places the valve body in the placement groove, and the clamping plate presses and fixes the valve body; the insertion block can be inserted into the valve body; the positioning hole positions the mounting hole of the valve body; the positioning groove and the positioning hole are in one-to-one correspondence, so that the mounting holes at both ends of the valve body can be in one-to-one correspondence; the compression spring can compress the positioning pin into the positioning groove when no hole is drilled, and after the mounting hole is drilled at one end of the valve body, the positioning pin can enter the mounting hole, thereby quickly positioning.

[0016] like Figure 1-4 As shown, a positioning assembly for machining a drilling mud pump valve body includes a fixed base plate 1 mounted on a lathe. A placement groove 2 for placing the valve body is provided at the center of the fixed base plate 1. Two vertically arranged fixing rods 3 are symmetrically arranged on both sides of the placement groove 2. A clamping plate 4 passes through the two fixing rods 3. Several positioning holes 5 are distributed around the circumference of the clamping plate 4. Connecting plates 6 are provided on both sides of the clamping plate 4. The connecting plates 6 pass through the fixing rods 3. Fixing nuts 7 are installed on the fixing rods 3 and at the top and bottom of the clamping plate 4.

[0017] Specifically, the base plate 1 is fixedly installed on the drilling machine. The base plate 1 has a fixing slot. The valve body 13 that needs to be drilled is placed in the placement slot 2. At this time, there are no holes at both ends of the valve body. Then, the connecting plate 6 is set through the fixing rod 3 and fixed with the fixing nut 7. The drill bit of the drilling machine passes through the positioning hole 5 to drill the valve body 13. The clamping plate 4 presses down on the valve body 13 to prevent it from moving randomly.

[0018] An insertion block 8 is fixedly connected to the bottom of the clamping plate 4. The insertion block 8 cooperates with the valve body 13. Specifically, the insertion block 8 is made of rubber. The insertion block 8 is inserted into the through hole of the valve body 13 with an interference fit. The insertion block 8 can limit and fix the valve body 13 in the left and right directions.

[0019] The inner circumference of the placement groove 2 is distributed with several positioning grooves 9 corresponding to the positioning holes 5; specifically, after the flange on the upper part of the valve body 13 is drilled, the valve body 13 is inverted so that the flange with the drilled hole is located in the placement groove 2, and the drilled hole corresponds one-to-one with the positioning groove 9, so that the positions of the holes at both ends of the valve body 13 are corresponding.

[0020] A vertically arranged compression spring 10 is fixedly connected inside the positioning groove 9. A positioning pin 11 is fixedly connected to the top of the compression spring 10. Specifically, when neither end of the valve body 13 has a hole, the flange at the end of the valve body 13 presses down the compression spring 10, and the positioning pin 11 is pressed into the positioning groove 9. After a hole is drilled at one end of the valve body 13, the drilled end is placed in the placement groove 2. The drilled hole corresponds to the positioning groove 9, and the positioning pin 11 enters into the drilled hole on the valve body 13, so that the holes drilled at the upper and lower ends of the valve body 13 correspond one-to-one.

[0021] Guide posts 12 are provided at the bottom of the positioning post 11 and at the top of the positioning groove 9, and compression spring 10 is located outside the guide post 12.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
