Description

Technical Field

[0001] This utility model relates to the field of mechanical testing equipment technology, and in particular to a fixing clamping device for pump testing. Background Technology

[0002] Pump body testing is an indispensable part of pump body production and R&D. However, pump bodies require stable clamping and positioning during testing to ensure their position and state remain unchanged, thus avoiding impacts on test accuracy. Traditional pump body fixing methods often use simple clamps or manual support, which have several drawbacks. For example, clamping devices often suffer from uneven clamping force distribution leading to pump body deformation, unstable clamping, and inaccurate positioning, making it difficult to meet the demands of high-precision pump body testing. Therefore, there is an urgent need for a fixing and clamping device that can stably clamp and accurately position the pump body under test to improve the efficiency and accuracy of pump body testing. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides a fixing clamping device for pump testing. This device is mainly used to stably and reliably clamp and position the pump body under test during the pump body testing process, so as to ensure the smooth progress of the testing process and the accuracy of the test results.

[0004] To achieve the above objectives, this utility model provides a fixing and clamping device for pump testing, including a base platform, a support platform disposed on the base platform, and a pump body to be tested on the support platform; a fixing ring is installed on the pump body to be tested, and circular holes are symmetrically arranged on the fixing ring; an external interface is also provided on the pump body to be tested for connecting external testing equipment; a positioning base is provided on the support platform for supporting the pump body to be tested; a downward clamping mechanism is also arranged side by side on the support platform, and a connecting block is installed at the lower end of the base platform; mounting plates are symmetrically arranged at the lower end of the connecting blocks, and a lifting support mechanism is installed on the mounting plates.

[0005] In operation, the pump body to be tested is first placed on the positioning base of the support platform, and its arc-shaped groove and rubber buffer layer are used to achieve initial positioning and shock absorption. Then, the first drive device of the pressing clamping mechanism is activated, which drives the first connecting rod to move the first connecting block up and down. The second connecting rod links the clamping block, so that the cylindrical telescopic block is inserted into the circular hole of the fixing ring and a dynamic clamping force is applied. At the same time, the second drive device of the lifting support mechanism is activated, and the height is adjusted by the telescopic rod assembly so that the anti-slip soft pad of the lifting block is in contact with the bottom of the pump body to form a two-way clamping. The support rod and the lifting block can be quickly disassembled for maintenance by the bolt locking assembly. Finally, the test equipment is connected through the external interface of the pump body to be tested, and the test is started after the fixation is completed.

[0006] The beneficial effects of this utility model are as follows: This utility model uses a positioning base to support the pump body under test, and a downward clamping mechanism is arranged side-by-side on the support platform. Simultaneously, a lifting support mechanism is installed at the lower end of the base platform, forming a bidirectional clamping force. Combined with the circumferential constraint of the fixing ring, this effectively achieves stable clamping and accurate positioning of the pump body under test. The arc-shaped groove inside the positioning base matches the bottom shape of the pump body under test, and a rubber buffer layer is embedded in the inner wall of the groove, effectively protecting the pump body under test and improving clamping stability. The downward clamping mechanism drives the clamping block to move up and down via a first driving device. The telescopic block at the bottom of the clamping block can be inserted into the circular hole on the fixing ring, further enhancing the clamping firmness. The lifting support mechanism drives the telescopic rod to extend and retract via a second driving device, causing the lifting block to move synchronously up and down, providing reliable support for the pump body under test. Furthermore, the design of the telescopic block makes its diameter smaller than the diameter of the circular hole on the fixing ring, facilitating insertion and fixation. The bolt locking assembly facilitates the individual disassembly and replacement of the support rod and the lifting block.

[0007] As a further improvement of this utility model, in order to achieve rapid and accurate positioning, while providing better support and buffering effect and improving the reliability of test data, the positioning base is fixed at the center position of the support platform, and the positioning base is provided with an arc-shaped groove that matches the shape of the bottom of the pump body to be tested, and a rubber buffer layer is embedded in the inner wall of the groove.

[0008] As a further improvement of this utility model, in order to clamp the pump body under test downwards and stabilize it, the downward clamping mechanism includes a first driving device, on which a first connecting rod is mounted; a first connecting block is hinged to the top end of the first connecting rod, and a second connecting rod is provided at the other end of the first connecting block; a pressing block is also installed at the end of the second connecting rod, and a telescopic block is provided at the bottom end of the pressing block; the first driving device can drive the first connecting block to move up and down through the first connecting rod, and a base plate is also installed at the bottom end of the first driving device and fixed to the support platform through the base plate.

[0009] As a further improvement of this utility model, in order to provide stable upward support for the pump body under test, while increasing friction and dispersing pressure to avoid local wear at the bottom of the pump body, the lifting support mechanism includes a second driving device, on which a telescopic rod assembly is provided; a second connecting block is installed at the top of the telescopic rod assembly, and a support rod is clamped on the second connecting block; a lifting block is also provided at the upper end of the support rod, and an anti-slip soft pad is provided on the lifting block; the second driving device can drive the telescopic rod assembly to perform telescopic movement, thereby driving the lifting block to perform synchronous lifting and lowering movement.

[0010] As a further improvement of this utility model, in order to facilitate the insertion of the telescopic block into the circular hole on the fixing ring and avoid the pump body under test from rotating circumferentially, the telescopic block is a cylinder in whole, and the diameter of the telescopic block is smaller than the diameter of the circular hole on the fixing ring.

[0011] As a further improvement of this utility model, in order to improve the flexibility and maintainability of the device, simplify the disassembly and assembly process, and reduce maintenance costs, a bolt locking assembly is also provided on the second connecting block. The bolt locking assembly is used to fix the support rod. The support rod and the lifting block can be disassembled and replaced separately through the bolt locking assembly.
