Description

Technical Field

[0001] The utility model relates to the technical field of pressure resistance testing, in particular to a pressure resistance testing platform for hydraulic component processing. Background Art

[0002] Hydraulic parts are components used in hydraulic systems, such as the current hydraulic pumps, hydraulic motors, hydraulic cylinders, hydraulic valves, boosters, etc. During the production and processing of hydraulic components, it is necessary to use pressure testing equipment to test their strength. Only products that pass the test can be put into subsequent processing and use.

[0003] In the patent application with the authorization publication number of 2023-10-03 and the authorization publication date of 2023-10-03, and the name of "A hydraulic component pressure resistance detection device that is easy to fix", the pressure-resistant component to be tested is first placed at the center of the detection seat, and the pressure-resistant component is aligned with the pressure plate. Then the rotating hand wheel is manually turned, and the rotation of the rotating hand wheel drives the rotation of the lead screw, and the rotation of the lead screw drives the movement of the slider, and the movement of the slider drives the movement of the limit roller, and the limit roller is used to limit and fix the two sides of the tested hydraulic component. Then, the threaded push rod is manually rotated, and the threaded push rod is used to push the fixed block to move, and the fixed block is used to limit and fix the two sides of the tested hydraulic component to ensure that the tested hydraulic component is firmly fixed. Then, the electric hydraulic cylinder is turned on, and the pressure plate is pushed up and down by the electric hydraulic cylinder, and the pressure plate is used to perform pressure resistance detection on the hydraulic test component;

[0004] During the actual use of the above-mentioned device, in order to ensure the normal detection of the pressure plate, it is necessary to first place the pressure-resistant part to be detected on the center position of the detection seat, which increases the difficulty of operation for the staff and has low detection efficiency. When the next pressure-resistant part needs to be detected, it is necessary to first remove the pressure-resistant part on the detection seat and then fix the next pressure-resistant part, and the test time is relatively long.

[0005] Therefore, we proposed a pressure test bench for hydraulic component processing in order to solve the above problems. Utility Model Content

[0010] The upper end bearing of the central platform body is installed with a support frame body, and pressure test components are installed on both sides of the upper end of the support frame body, and a rotating drum is fixedly installed inside the lower end of the support frame body, and the rotating drum is connected to a rotating mechanism, and the rotating mechanism is used to drive the rotating drum to rotate 90° each time.

[0011] Furthermore, there are four bosses distributed at equal angles with respect to the center of the central platform, and the center of the central platform and the centers of the two withstand voltage test assemblies are located on the same plane.

[0012] Through the above technical solution, the two sets of pressure-resistant test components can be respectively opposite to the four bosses on the left, right, front and back after being rotated.

[0013] Furthermore, the two clamps are symmetrically distributed about the center of the pressure test assembly, and the pressure test assembly consists of a first electric push rod and a pressure block, and the first electric push rod is fixedly installed on the upper end of the support frame, and the pressure block is fixedly installed on the lower movable end of the first electric push rod.

[0014] Through the above technical solution, when the fixture fixes the test piece, it can ensure that the test piece and the pressing block are opposite to each other up and down, reducing the difficulty of operation.

[0015] Furthermore, opposite thread structures are provided at both ends of the rotating rod, and the rotating rod and the movable block are threadedly connected, and the movable block is fitted with the inner wall of the boss.

[0016] Through the above technical solution, after the rotating rod is rotated, the two movable blocks can be driven to move relative to each other.

[0017] Furthermore, the rotating mechanism includes a movable plate sleeved inside the rotating drum, the lower end of the movable plate is fixed to the upper movable part of the second electric push rod, and the second electric push rod is embedded and installed inside the central platform body.

[0018] Through the above technical solution, after the second electric push rod is started, it can drive the movable plate to move up and down inside the rotating drum.

The specific contents are as follows:

[0023] (1) The pressure-resistant part to be tested is placed between the two fixtures, and then the rotating rod is driven to rotate by the hand wheel. After the rotating rod rotates, the two movable blocks threadedly mounted on the outer side of the rotating rod move synchronously relative to each other by virtue of the fit with the boss, until the two fixtures are respectively fitted on both sides of the pressure-resistant part to be tested, thereby achieving the fixing operation of the pressure-resistant part to be tested. At this time, the pressure-resistant part to be tested is located at the center of the two fixtures. At the same time, since the two fixtures are symmetrically arranged about the center of the pressure-resistant test assembly, it can be ensured that the pressure-resistant test assembly and the pressure-resistant part to be tested are arranged relatively up and down, thereby reducing the difficulty of operation for the staff;

[0024] (2) When the two pressure test assemblies are conducting pressure tests on the pressure-resistant parts to be tested on the left and right bosses, the other two test pieces are fixed on the front and rear bosses respectively. When the pressure-resistant parts to be tested on the left and right bosses are tested, the second electric push rod is started, and the second electric push rod drives the movable plate to move up, and the movable plate drives the slider to slide inside the slide groove. Since the slide groove is spiral, it can drive the rotating drum, the support frame and the pressure test assembly to rotate 90 degrees. The centers of the two pressure test assemblies can be respectively distributed above and below the pressure-resistant parts to be tested on the front and rear bosses for subsequent testing operations, thereby shortening the test time and improving the efficiency of the pressure test of hydraulic components.
