Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to an actuator assembly and testing device. Background Technology

[0002] In the manufacturing process of electronic parking brake actuators, the assembled actuators undergo rigorous testing to ensure their performance and quality meet design requirements. Currently, the standard procedure involves removing the assembled actuator from its original assembly unit and placing it in a specialized testing facility. During testing, specific procedures and standards are followed to examine various performance indicators of the actuator, such as actuation accuracy, response time, and output force. After testing, if all actuator indicators pass, it must be removed from the testing facility for collection and storage for subsequent packaging, transportation, and sales.

[0003] However, this existing operating method has many drawbacks. First, the entire process is quite cumbersome, requiring multiple disassembly and reassembly operations of the actuator. Each disassembly and reassembly consumes a certain amount of time and manpower, which not only increases the labor intensity of workers but also prolongs the production cycle and reduces production efficiency.

[0004] To address the aforementioned issues, improve the efficiency and accuracy of actuator testing, and reduce production costs, this invention provides an actuator assembly and testing device. This device enables rapid docking and testing of the workpiece under test. After testing, the workpiece can be lifted directly by an external robotic arm to remove it from the original device, greatly simplifying the operation process and improving production efficiency.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: an actuator assembly and testing device, including a mounting base plate 1, a sliding integrated plate 2, a docking integrated device 3, a driving device 4, and a sensor 7. The sliding integrated plate 2, the driving device 4, and the sensor 7 are disposed on the same side of the mounting base plate 1. The driving end of the driving device 4 is connected to the sliding integrated plate 2, and is used to push the sliding integrated plate 2 to slide on the mounting base plate 1. The sliding integrated plate 2 is slidably connected to the mounting base plate 1. The sliding integrated plate 2 is connected to the docking integrated device 3, which is used to dock with the test piece. The sensor 7 is a photoelectric displacement sensor, which measures displacement by utilizing the time change of reflection or blockage of light signals (such as laser or infrared light).

[0019] The mounting base plate 1 is provided with a flange 11 for connecting an external robotic arm. After the test is completed, the external robotic arm can be connected to the mounting base plate 1 through the flange 11, and then it can be lifted directly to complete the process of clamping the test piece away from the original device.

[0020] It should be noted here that, such as Figure 1 As shown, the surface on which each component is installed is the bottom surface of the entire testing device. In actual application, the bottom surface of the mounting base plate 1 is fastened to the test piece.

[0021] The external robotic arm first moves the mounting base plate 1 directly above the test piece, aligns the docking integration device 3 with the test piece, and then activates the drive device 4 to cause the sliding integration plate 2 to make a small displacement, thereby inserting the docking integration device 3 into the socket of the test piece.

[0022] The docking integration device 3 includes a plug 33, multiple rotary clamping cylinders 31, and multiple positioning posts 32. The multiple rotary clamping cylinders 31 and multiple positioning posts 32 are evenly arranged on the sliding integration plate 2. The positioning posts 32 are used to position the test piece. The rotary clamping cylinders 31 are used to hook the test piece. The driving end of the rotary clamping cylinder 31 is provided with an L-shaped connector. The plug 33 is detachably connected to the center of the sliding integration plate 2. The plug 33 is used to make an electrical connection with the test piece to realize power-on testing.

[0023] The rotary clamping cylinder 31 is a pneumatic actuator that combines rotary motion with linear clamping action. It drives the piston with compressed air, and the piston rod rotates synchronously (usually 90° or 180°) during extension and retraction, which drives the clamping arm to avoid the workpiece and avoid interference. In this utility model, a 90° rotation is used. After the rotation is in place, the piston continues to extend and clamps and fixes the workpiece through the clamping arm.

[0024] Gas pressure drives the piston to move. The piston has an L-shaped groove, and the inner wall of the outer shell has a fixed protrusion. When the piston moves, it rotates according to the connection between the L-shaped groove and the fixed protrusion. The gas pressure is usually 0.1MPa~1.0MPa. The rotary clamping cylinder 31 is a ready-made cylinder in the prior art, also known as a corner clamping cylinder, so it will not be described in detail in this article.

[0025] And such as Figure 1 As shown, the positions of the multiple rotary clamping cylinders 31 should not interfere with the workpiece under test when the drive device 4 pushes. In this utility model, it is best to use three rotary clamping cylinders 31. The three rotary clamping cylinders 31 form a triangle, which can not only avoid interference with the workpiece under test during docking, but also play a role in stable connection.

[0026] The sliding integrated plate 2 includes a sliding plate 21 and an auxiliary mounting plate 22. The auxiliary mounting plate 22 is detachably connected to the sliding plate 21. The auxiliary mounting plate 22 can be replaced according to different testing requirements to adapt to the testing of actuators of different specifications.

[0027] The sliding integrated plate 2 also includes a circuit integrated plate 23, which is disposed on the sliding plate 21. The circuit integrated plate 23 is used to integrate the electrical circuits required for testing, making the circuit layout more neat and standardized, facilitating maintenance and management, and providing a variety of different interfaces for staff to use, making it more adaptable to different testing conditions.

[0028] The driving device 4 includes a driving cylinder 41 and a connecting block 42. The driving cylinder 41 is connected to the mounting base plate 1. The driving end of the driving cylinder 41 is connected to the connecting block 42. The connecting block 42 is connected to the sliding plate 21. Through the extension and retraction movement of the driving cylinder 41, the connecting block 42 and the sliding plate 21 are driven to slide on the mounting base plate 1.

[0029] The drive cylinder 41 mentioned here is a compact cylinder. Under the same working capacity, the compact cylinder can further reduce the space occupied and is more suitable for test conditions.

[0030] The mounting base plate 1 is provided with multiple slide rails 5. The connecting block 42 is slidably connected to one of the slide rails 5, and the sliding integrated plate 2 is slidably connected to the other slide rails 5. The slide rails 5 provide guidance for the sliding of the connecting block 42 and the sliding integrated plate 2, ensuring the smoothness and accuracy of the sliding.

[0031] The mounting base plate 1 is connected to a cable protection chain 6, which is used to protect the cable used in the test process, prevent the cable from being worn or pulled during sliding, and extend the service life of the cable.

[0032] Working principle: 1. Testing Process This utility model is used to test electronic parking brake actuators. The sensor 7 is used to test the displacement of the actuator end of the test piece, that is, the shoe or caliper.

[0033] The external robotic arm first moves the mounting base plate 1 directly above the test piece, and activates multiple rotary clamping cylinders 31 to extend their positions. After aligning the docking integration device 3 with the test piece, the driving device 4 is activated to cause a small displacement of the sliding integration plate 2, thereby electrically connecting the plug 33 in the docking integration device 3 to the test piece, enabling power-on testing. The drive end connector of the rotary clamping cylinder 31 abuts against the outer flange of the test piece.

[0034] During the test, the sensor 7 monitors the displacement parameters of the actuator end of the device under test in real time and transmits the monitoring data to the control system for analysis and processing. If the displacement of the actuator end meets the design requirements, the test is qualified; if it does not meet the requirements, the test is unqualified, and the actuator needs further debugging or repair.

[0035] 2. The process of separation After the test is completed, the test piece is lifted by an external robotic arm to detach it from the original device. The staff can then collect and put away the test pieces, collect and put away qualified actuators, and mark and send unqualified actuators for repair.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
