Description

Technical Field

[0001] This utility model relates to the field of measuring fixture technology, and more specifically to a pump head measuring fixture. Background Technology

[0002] In industrial production, the machining and manufacturing of pump heads is a crucial step in many mechanical manufacturing fields. The precision and quality of the pump head directly affect the performance and reliability of the entire pump system. To ensure the machining accuracy of the pump head, precise measurements of each hole or other structure on the pump head are required. However, existing measurement methods and tools have many shortcomings when measuring pump heads.

[0003] Traditional methods typically involve placing the pump head directly on a workbench and then using measuring instruments to measure the holes and other structures on the pump head. This method has several problems: First, the placement of the pump head is difficult to control precisely, leading to inaccurate measurement references and consequently affecting measurement accuracy. Second, measuring holes at different locations on the pump head requires multiple adjustments, making the operation cumbersome and inefficient. Furthermore, while some existing measuring fixtures can provide some fixation and positioning for the pump head, their complex structures, inconvenient adjustments, and inability to meet the measurement needs of different pump head models and specifications are unacceptable.

[0004] To address the aforementioned issues, there is an urgent need for a fixture capable of efficiently and accurately measuring pump heads, thereby improving measurement efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pump head measuring fixture. The overall structure of this pump head measuring fixture is relatively simple, enabling the positioning and placement of the pump head for efficient and convenient measurement in conjunction with a CNC turntable and measuring instruments. Furthermore, during the initial clamping of the pump head, the measurement position can be adjusted simply by moving the placement seat and using the position adjustment component, facilitating the measurement of multiple different position structures and improving the measurement efficiency of multiple different position structures.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pump head measuring fixture includes a base and a placement seat. The placement seat is disposed on the base and is horizontally slidably connected to the base. Reference blocks are respectively disposed on both sides of the base in the sliding direction of the placement seat. Position adjustment components are disposed on the reference blocks.

A plurality of positioning components are disposed on the placement surface. A plurality of connecting holes are provided on the base, and positioning protrusions are provided on the bottom of the base.

[0008] Furthermore, the base is provided with a slide rail, and the bottom of the placement seat is provided with a slide groove. The placement seat is placed on the base and the slide groove cooperates with the slide rail.

[0009] Furthermore, the reference block is detachably connected to the placement seat, and the reference block is provided with a threaded hole. The position adjustment assembly includes an adjustment bolt that passes through the threaded hole, and a connector is provided on the end of the adjustment bolt facing the placement seat.

[0010] Furthermore, the connecting component is a magnetic block, which is detachably connected to the adjusting bolt and can magnetically connect to the placement base.

[0011] Furthermore, the positioning element comprises several positioning posts.

[0012] Furthermore, the placement surface is an inclined plane.

[0013] Furthermore, a countersunk hole is provided on the base at the connection hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The pump head measuring fixture of this utility model has a relatively simple overall structure.

[0025] Preferably, the base 1 is provided with a slide rail 8, and the bottom of the placement seat 2 is provided with a sliding groove. The placement seat 2 is placed on the base 1 and the sliding groove cooperates with the slide rail 8, thereby realizing the horizontal sliding connection between the placement seat 2 and the base 1.

The position adjustment assembly includes an adjustment bolt 4, which passes through the threaded hole, and a connector is provided on the end of the adjustment bolt 4 facing the placement seat 2.

[0027] Specifically, the reference block 3 and the placement seat 2 can be detachably connected by bolts;

[0028] Specifically, the position adjustment component is set as the adjustment bolt 4. When adjusting the reference of the placement seat 2, it is only necessary to rotate the adjustment bolt 4 to move the reference positions on both sides of the placement seat 2, thereby facilitating adjustment.

[0029] Preferably, the connector is a magnetic block 5, which is detachably connected to the adjusting bolt 4 and can magnetically connect the placement seat 2, thereby quickly achieving the connection and fixation of the placement seat 2.

[0030] Preferably, the positioning element is a plurality of positioning pins 6, which are detachably connected to the placement seat 2. The detachable connection method can be a connection using threaded holes and bolts.

[0031] Preferably, the placement surface 7 is an inclined surface. Based on the layout of the holes to be measured on the pump head 12, the pump head 12 is positioned by the inclined surface 7, so that the holes to be measured are in a horizontal state, which facilitates measurement.

[0032] Preferably, the base 1 has a countersunk hole 11 at the connection hole 10, so that when the base 1 is installed on the CNC turntable, the bolt head used to install and fix the base 1 can be located in the countersunk hole 11, making the top plane of the base 1 flush and avoiding interference with the movement of the placement seat 2.

[0033] Measurement process:

[0034] When measuring the hole on the pump head 12, the base 1 is first positioned and installed on the CNC turntable, and positioned and connected by the positioning protrusion 9 and several connecting holes 10; then the pump head 12 is placed on the placement surface 7 of the placement seat 2 and positioned by several positioning pins 6; then the placement seat 2 is moved to one side of the base 1 according to the hole to be measured, and fixed by magnetic attraction block 5; finally, the measuring instrument's detection head is inserted into the hole on the pump head 12, and the hole on the pump head 12 is measured in conjunction with the rotation of the CNC turntable to obtain the measurement data.

[0035] The pump head measuring fixture of this utility model has a relatively simple overall structure. It can position and place the pump head 12, change the placement state of the structure on the pump head 12 during measurement, and perform efficient and convenient measurement in conjunction with a CNC turntable and measuring instruments. Furthermore, by moving the placement seat 2 horizontally and setting two reference blocks 3 and a position adjustment component, the pump head 12 can be clamped once, and the measurement position can be adjusted by moving the placement seat 2 and using the position adjustment component. This facilitates the measurement of multiple structures at different positions and improves the measurement efficiency of multiple structures at different positions.
