Description

Technical Field

[0001] The utility model belongs to the technical field of actuator testing, and in particular relates to an actuator testing bench. Background Art

[0002] A pneumatic actuator is a device that uses air pressure to open, close, or regulate valves. It is also known as a pneumatic actuator or pneumatic device, and is often referred to colloquially as a pneumatic head. It plays a vital role in automation systems and is widely used in various industrial fields. Performance testing of pneumatic actuators requires an actuator test bench.

[0003] The actuator test bench is a tool used to test and evaluate the performance of actuator systems. It can simulate multiple operating scenarios and perform detailed performance and load tests on actuators to ensure that the actuator system can maintain stable operation in high-concurrency and large-data volume scenarios.

[0004] However, it is worth noting that the size of the placement plate of the current actuator test bench is fixed, while the sizes of actuators vary. Small actuators can be fixed normally on the placement plate, but for longer actuators, at least one end will be in a suspended state when fixed. In this case, the actuator is not fixed firmly on the surface of the placement plate, which will affect the test of the actuator and reduce the test efficiency of the actuator. Utility Model Content

[0005] The purpose of the present utility model is to provide an actuator test bench, which aims to solve the problem that the size of the placement plate of the actuator test bench is fixed, while the sizes of the actuators are different. Actuators with small sizes can be fixed normally on the placement plate, but for actuators with longer lengths, at least one end will be in a suspended state when fixed. In this case, the actuator is not fixed firmly on the surface of the placement plate, which will affect the test of the actuator and reduce the test efficiency of the actuator.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an actuator test bench, comprising a test bench body, a mounting plate, and a bracket, wherein the mounting plate is mounted on the upper surface of the test bench body, the top of the mounting plate is connected to the bracket, and the top of the bracket is connected to a placement plate;

[0007] A guide groove is provided on the side surface of the bracket, a guide rail is connected to the inside of the guide groove, an extension plate is connected to the upper surface of the guide rail, a connecting block is connected to the bottom side of the extension plate, a bidirectional screw rod passes through the inside of the connecting block, a second bearing is installed between the bidirectional screw rod and the bracket, and a handwheel is connected to the end of the bidirectional screw rod.

[0008] In order to limit the movement direction of the extension plate, as an actuator test bench of the present invention, preferably, the guide rail is slidably connected to the bracket through a guide slot.

[0009] In order to adjust the position of the extension plate, as an actuator test bench of the utility model, the bidirectional screw and the connecting block are threadedly connected, and the bidirectional screw forms a rotating structure with the bracket through the second bearing.

[0010] As an actuator test bench of the utility model, preferably, the surface of the extension plate is connected to a stand, a sliding groove is provided on the surface of the stand, an external threaded barrel is passed through the interior of the sliding groove, a first nut is sleeved on the surface of the external threaded barrel located on the lower surface of the stand, a second nut is sleeved on the surface of the external threaded barrel located on the upper surface of the stand, a threaded rod is passed through the interior of the external threaded barrel, a first bearing is installed at the bottom of the threaded rod, the surface of the first bearing is connected to an extrusion seat, the bottom side surface of the extrusion seat is connected to a rubber pad, and the top of the threaded rod is connected to a turntable.

[0011] In order to fix actuators of different shapes, as an actuator test bench of the present invention, preferably, the externally threaded barrel is slidably connected to the stand via a sliding groove.

[0012] In order to fix the position of the externally threaded barrel, as an actuator test bench of the present invention, preferably, the first nut and the externally threaded barrel are threadedly connected, and the second nut and the externally threaded barrel are threadedly connected.

[0013] In order to fix the actuator, as an actuator test bench of the present invention, preferably, the threaded rod and the external threaded barrel are threadedly connected, and the threaded rod forms a rotating structure through the first bearing and the extrusion seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the handwheel is rotated, the bidirectional screw can be driven to rotate. The rotation of the bidirectional screw can drive the extension plate to move horizontally through the connecting block. In this way, the distance between the placement plate and the extension plate can be adjusted, so that it can adapt to actuators of different lengths, thereby avoiding the actuator being too long and causing part of it to be suspended in the air, affecting the test structure, and improving the applicability of the test bench.

[0016] After the adjustment of the sliding groove is completed, the external threaded barrel can rotate the second nut, and the second nut can move downward when rotating on the surface of the external threaded barrel. When the second nut moves downward to the surface of the stand, the position of the external threaded barrel stand can be fixed. The turntable can drive the threaded rod to move downward when rotating inside the external threaded barrel. The downward movement of the external threaded barrel can drive the extrusion seat to move downward through the second bearing. When the extrusion seat drives the rubber pad to move downward, the actuator can be fixed in this way, thereby facilitating the position fixation of actuators of different shapes.
