Description

Technical Field

[0001] This utility model relates to the field of hydraulic testing equipment technology, specifically a support structure for testing the performance of a hydraulic pump. Background Technology

[0002] A hydraulic pump is the power component of a hydraulic system. Driven by an engine or electric motor, it converts mechanical energy into hydraulic energy and provides pressurized oil to the hydraulic system. The performance of the hydraulic pump has a significant impact on the performance of the hydraulic system. Therefore, hydraulic pumps need to undergo performance testing during the production and processing process. As a result, support structures are needed to assist in improving the reliability and stability of the testing process.

[0003] The prior art, disclosed in patent document CN221824025U, presents the following technical solution: a test bench for a hydraulic pump, comprising a test bench and a lifting mechanism. The top of the test bench is provided with several detectors and a controller. The controller is provided with a control panel and several indicator lights. The top of the test bench is provided with a concave clamping groove. The bottom of the test bench is provided with a lifting mechanism, which includes a lifting platform and a support rod. The bottom of the test bench is provided with a driving component.

[0004] The driving component at the bottom of the above technical solution raises and lowers itself by driving a screw rod. The single screw rod bears a large load, which can cause the driving component to overload and be damaged. In addition, the clamping and fixing rely on a pre-set groove, which has poor compatibility. Utility Model Content

[0005] The purpose of this invention is to provide a support structure for testing the performance of a hydraulic pump, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support structure for testing the performance of a hydraulic pump, comprising a base, transmission boxes being fixedly installed at both the front and rear ends of the base, uprights being fixedly connected to both the left and right ends of the transmission boxes, a mounting frame being fixedly connected to the upper outer wall of the uprights, and clamping components being installed at both ends of the mounting frame.

[0007] The transmission box is rotatably connected to a rotating rod. Both ends of the rotating rod are equipped with driving bevel gears. The teeth of the driving bevel gears are meshed with driven bevel gears. The driven bevel gears are located below the upright. The upright has a screw rod inside, which is connected to the driven bevel gear at its bottom. The outer wall of the screw rod is threaded with a threaded sleeve. A limit block is fixedly connected to the circumference of the lower outer surface of the threaded sleeve. A limit groove is formed on the circumference of the inner wall of the upright. The outer wall of the limit block and the inner wall of the limit groove are slidably connected. A connecting plate is fixedly connected to the top side of the threaded sleeve. A support platform is provided on the top side of the connecting plate via screws.

[0008] In the above technical solution, the support platform can be raised and lowered by driving the rotating rod, bevel gear set, screw and threaded sleeve, so that the hydraulic pump can be adjusted between the clamping components at both ends, thereby adapting to the clamping and positioning of various hydraulic pumps. Furthermore, the screws are symmetrically arranged at the four corners of the support platform, and the synchronous drive makes the load evenly distributed, improving the service life of the support structure.

[0009] The clamping assembly includes a limiting rod, which is slidably disposed at the front and rear ends of the mounting frame. Each of the two limiting rods has a fixing plate at one end on its inner side, and clamping seats are provided at both the upper and lower ends of the fixing plate by screws.

[0010] In the above technical solution, clamping components are installed on both sides of the support platform, and the distance between the clamping seats at both ends is adjusted by an electric push rod, which can accommodate hydraulic pumps of various shapes and sizes.

[0011] As a further preferred embodiment of this technical solution, mounting holes are provided at both ends of the base, and the mounting holes are connected to the base by bolts.

[0012] As a further preferred embodiment of this technical solution, a motor is installed on one side of one end of the rotating rod, and the two rotating rods are connected by a conveyor belt.

[0013] As a further preferred embodiment of this technical solution, each of the connecting plates is provided with a rubber pad at its bottom edge, so that when the support platform is lowered and reset, the rubber pad contacts the top side of the upright.

[0014] The above technical solution can reduce the damage to the hydraulic pump, support platform, or uprights caused by the lowering of the support platform.

[0015] As a further preferred embodiment of this technical solution, the limiting groove is vertically arranged and is a certain distance away from the opening end above the upright.

[0016] In the above technical solution, the threaded sleeve that is raised and lowered can be prevented from coming loose, and the limiting block slides in the limiting groove to limit the movement.

[0017] As a further preferred embodiment of this technical solution, each of the fixed plates is equipped with an electric push rod in the middle, and the electric push rod is located on the outside of both ends of the mounting frame.

[0018] As a further preferred embodiment of this technical solution, the inner side of the clamping seat is designed in a V-shape, and anti-slip grooves are formed along the slot.

[0019] In the above technical solution, an anti-slip groove is provided at the V-shaped clamping opening of the clamping seat to improve the clamping effect, and the clamping seat is set up vertically to effectively suppress axial displacement during hydraulic pump testing.

[0020] This utility model provides a support structure for testing the performance of a hydraulic pump, which has the following advantages:

[0021] (1) This utility model enables the support platform to be raised and lowered by driving the rotating rod, bevel gear set, screw and threaded sleeve, so that the hydraulic pump can be adjusted between the clamping components at both ends, thereby adapting to the clamping and positioning of various hydraulic pumps. Furthermore, the screws are symmetrically arranged at the four corners of the support platform, and the synchronous drive makes the load evenly distributed, thus improving the service life of the support structure.

[0022] (2) This utility model can be adapted to hydraulic pumps of various sizes by installing clamping components on both sides of the support platform and adjusting the distance between the clamping seats at both ends by electric push rod. The clamping seat has anti-slip grooves at the V-shaped clamping opening to improve the clamping effect. The clamping seats are set up vertically to effectively suppress axial displacement during hydraulic pump testing. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a support structure for testing the performance of a hydraulic pump includes a base 1. The base 1 has mounting holes at both ends, which are connected to the base by bolts. A transmission box 2 is fixedly installed at both the front and rear ends of the base 1. A vertical rod 3 is fixedly connected to both the left and right ends of the transmission box 2. A mounting bracket 4 is fixedly connected to the upper outer wall of the vertical rod 3. A clamping component 5 is installed at both ends of the mounting bracket 4.

[0030] like Figure 2 and Figure 3As shown, rotating rods 21 are rotatably connected inside the transmission box 2. A motor 28 (model YBX3) is installed on one side of one end of the rotating rod 21. The two rotating rods 21 are connected by a conveyor belt. Both ends of the rotating rod 21 are provided with driving bevel gears 22. The teeth of the driving bevel gears 22 are meshed with driven bevel gears 23. The driven bevel gears 23 are located below the upright 3. The upright 3 is provided with screws 24 through bearings. The bottom of the screws 24 is connected to the driven bevel gears 23. The outer wall of the screws 24 is threaded with threaded sleeves 25. Limit blocks 251 are fixedly connected to the circumferential direction of the lower outer surface of the threaded sleeves 25. Limit grooves 31 are opened in the circumferential direction of the inner wall of the upright 3. The outer wall of the limit blocks 251 is fixed. The support platform 27 is slidably connected to the inner wall of the limiting groove 31. The limiting groove 31 is set vertically and is a certain distance away from the upper opening end of the upright 3. The top side of the threaded sleeve 25 is fixedly connected to the connecting plate 26. The bottom edge of the connecting plate 26 is provided with a rubber pad. When the support platform 27 is lowered and reset, the rubber pad contacts the top side of the upright 3. The top side of the connecting plate 26 is provided with the support platform 27 by screws. By driving the rotating rod 21, bevel gear set, screw 24 and threaded sleeve 25, the support platform 27 can be raised and lowered, so that the hydraulic pump is adjusted between the two clamping components 5 at both ends, thus adapting to the clamping and positioning of various hydraulic pumps. The screws 24 are symmetrically arranged at the four corners of the support platform 27, and the synchronous drive makes the load evenly distributed and improves the service life of the support structure.

[0031] like Figure 1 and Figure 4 As shown, each of the fixed plates 52 is equipped with an electric push rod 51, model YS607. The electric push rod 51 is located on the outside of both ends of the mounting frame 4. The clamping assembly 5 includes a limiting rod 54, which is slidably located at the front and rear ends of the mounting frame 4. Each of the two limiting rods 54 has a fixed plate 52 on one side of its inner side. The upper and lower ends of the fixed plate 52 are equipped with clamping seats 53 by screws. The inner side of the clamping seats 53 is V-shaped and anti-slip grooves are opened along the slot. By installing the clamping assembly 5 on both sides of the support platform 27 and adjusting the distance between the clamping seats 53 at both ends by the electric push rod 51, it can be adapted to hydraulic pumps of various sizes. The anti-slip grooves at the V-shaped clamping opening of the clamping seat 53 improve the clamping effect. The clamping seats 53 are set up vertically to effectively suppress axial displacement during hydraulic pump testing.

[0032] This utility model provides a support structure for testing the performance of a hydraulic pump. The specific working principle is as follows: The hydraulic pump to be tested is placed on the support platform 27. Based on the size of the hydraulic pump, it is adjusted to be between the clamping components 5 at both ends. The motor 28 is started via an external control module, and the transmission belt drives the rotating rods 21 on both sides to rotate. This causes the active bevel gear 22 to drive the driven bevel gear 23 to rotate, resulting in the rotation of the screw 24. The threaded sleeve 25 rises and falls on the screw 24, while the limiting block 251 slides and guides within the limiting groove 31, causing the support platform 27 to rise and fall until the hydraulic pump on the support platform 27 is adjusted to be between the clamping seats 53 at both ends. The electric push rod 51 is then activated, causing the clamping seats 53 at both ends to move towards the hydraulic pump. The pump is clamped and positioned by the V-shaped grooves on the clamping seats 53. The vertical arrangement of the clamping seats 53 effectively suppresses axial displacement during the hydraulic pump test. After clamping, the hydraulic pump's performance can be tested.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
