Description

Technical Field

[0001] This utility model relates to the field of electromagnetic clutch technology, specifically to a horizontal force measuring device for an electromagnetic actuator of an electromagnetic clutch. Background Technology

[0002] Currently, the design, manufacturing, and testing of automotive parts are increasingly moving towards higher precision. An electromagnetic clutch is a friction clutch that uses electromagnetic force for remote control. It relies on the switching of an energized coil to control the clutch's engagement and disengagement, and is widely used in machine tools and mechanical transmission systems. The electromagnetic actuator is a crucial component of the electromagnetic clutch. The main function of an electromagnetic clutch is to apply force to the clutch through electromagnetic induction. Therefore, testing the electromagnetic force generated by the actuator is essential for evaluating its efficiency.

[0003] Traditional electromagnetic actuator electromagnetic force measurement devices are vertical. These devices first clamp the actuator under test onto a table using fixtures, then generate a magnetic field in the electromagnetic coil by passing an electric current. The magnetic lines of force act on the coil on the table, producing reciprocating vibrations in the vertical direction according to the Lorentz force principle. The electromagnetic force of the device is then measured using these vibrations. However, due to the wide variety of electromagnetic actuators, different models require different fixtures, and the vertical orientation is inconsistent with the product's operating conditions. This necessitates weighing the parts and calculating the force, resulting in slow changeover times, high costs, and cumbersome operation. Utility Model Content

[0004] This utility model provides a horizontal force measuring device for the electromagnetic actuator of an electromagnetic clutch, solving the technical problems of the above-mentioned vertical electromagnetic force testing device being incompatible with the operating conditions of the electromagnetic actuator, and the need to change different fixtures to test different electromagnetic actuators, resulting in slow changeover, high cost, and cumbersome operation. The technical solution is as follows:

[0005] A horizontal force measuring device for the electromagnetic actuator of an electromagnetic clutch includes a force gauge, a telescopic component, a linear drive mechanism, and a chuck for holding the electromagnetic actuator coil. The force gauge and the telescopic component are respectively connected to the linear drive mechanism. The device includes a bracket, a mounting base, a fixed plate, a positioning shaft for supporting the armature, and a retaining ring for limiting the armature. The chuck is fixed to one end of the bracket, and the fixed plate is fixed to the other end of the bracket. The bracket has a through hole. The mounting base is connected to the fixed plate, and the positioning shaft is connected to the mounting base. The positioning shaft passes through the retaining ring and slides with the retaining ring. The positioning shaft engages with the through hole and also engages with the chuck.

[0006] Furthermore, the linear drive mechanism includes a lead screw mechanism and a guide mechanism, with the lead screw mechanism cooperating with the guide mechanism.

[0007] Furthermore, the lead screw mechanism includes a lead screw, a nut, and a motor. The nut is connected to the guide mechanism, the lead screw is engaged with the nut, and the motor is connected to the lead screw.

[0008] Furthermore, the guiding mechanism includes a guide rail, a slider, a slide table, and a connecting seat. The slider cooperates with the guide rail, the slide table is connected to the slider, the slide table is also connected to the lead screw mechanism, and the connecting seat is connected to the slide table.

[0009] In this invention, the linear drive mechanism is connected to the force gauge and the telescopic component, and the chuck is connected to the bracket. The electromagnetic actuator being measured has an electromagnetic coil and an armature. The armature is inserted into the positioning shaft, and the electromagnetic coil is connected to the chuck. The lead screw mechanism in the linear drive mechanism drives the guide mechanism to displace, thereby moving the force gauge and the telescopic component to the electromagnetic actuator being measured to measure the electromagnetic force. In this invention, because the chuck's jaws can move radially along the chuck, electromagnetic coils of different models of electromagnetic actuators can be fixed. Furthermore, the positioning shaft can support the armature, and the armature engages with the through hole on the bracket. This allows the device to measure different models of electromagnetic actuators without changing different types of clamps, offering the advantage of convenient operation. Moreover, this invention is horizontal, which is consistent with the operating conditions of electromagnetic actuators. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 5As shown, the horizontal force measuring device of the electromagnetic actuator of the electromagnetic clutch of this utility model includes a force gauge 1, a telescopic component 2, a linear drive mechanism, and a chuck 3 for clamping the electromagnetic actuator coil. The force gauge 1 and the telescopic component 2 are respectively connected to the linear drive mechanism. The telescopic component 2 consists of a cylinder, a piston rod, and a spring. The spring is located in the cylinder, with one end of the spring abutting against the cylinder and the other end of the spring abutting against one end of the piston rod. One end of the piston rod is located in the cylinder.

[0018] This utility model also includes a bracket 4, a mounting base 5, a fixing plate 6, a positioning shaft 7 for supporting the armature, and a retaining ring 8 for limiting the armature. The chuck 3 is fixed to one end of the bracket 4, and the fixing plate 6 is fixed to the other end of the bracket 4 by screws. The screws used for fixing are longer than the screw holes on the fixing plate 6, so that there is a clearance space 4b between the fixing plate 6 and the bracket 4 to facilitate the installation of the armature. The bracket 4 is provided with a through hole 4a. The mounting base 5 is connected to the fixing plate 6, and the positioning shaft 7 is connected to the mounting base 5. The positioning shaft 7 passes through the retaining ring 8 and slides with the retaining ring 8. The positioning shaft 7 cooperates with the through hole 4a and also cooperates with the chuck 3.

[0019] The linear drive mechanism includes a lead screw mechanism and a guide mechanism, with the lead screw mechanism cooperating with the guide mechanism. The lead screw mechanism includes a lead screw 9, a nut 10, and a motor 11. The nut 10 is connected to the guide mechanism, and the lead screw 9 and nut 10 are threaded together. The motor 11 is connected to the lead screw 9. The motor 11 is a servo motor, which has high precision and is convenient for accurate measurement of electromagnetic force.

[0020] The guiding mechanism includes a guide rail 12, a slider 13, a slide table 14, and a connecting seat 15. The two guide rails 12 are distributed in parallel and located at both ends of the lead screw 9. The slider 13 is slidably engaged with the guide rail 12. The slide table 14 is connected to the slider 13 and is also fixed to the nut 10. The connecting seat 15 is L-shaped. The horizontal end face of the connecting seat 15 is connected to the slide table 14, and the vertical end face is connected to the force measuring device 1 and the telescopic component 2.

[0021] There are two specific working processes of this utility model:

[0022] The first method involves first installing the electromagnetic actuator to be tested in place, that is, placing the armature on the positioning shaft 7 and clamping the electromagnetic coil with the chuck 3. Then, the lead screw mechanism drives the guide mechanism to move forward until the guide mechanism brings the force gauge 1 and the telescopic component 2 to the support mechanism. After that, the lead screw mechanism continues to drive the guide mechanism to move forward. Since the length of the telescopic component 2 is slightly longer than that of the force gauge 1, as the guide mechanism moves forward, the telescopic component 2 first presses against the armature, causing the armature to move axially along the positioning shaft 7 until it presses against the retaining ring 8. The telescopic component 2 then retracts, making the axial end face of the telescopic component 2 and the force gauge 1 flush. Then, the electromagnetic coil is energized, and the armature is attracted by the magnetic force and moves towards the direction of the electromagnetic coil. The armature, in turn, applies a force to the force gauge 1. At this point, the electromagnetic force on the armature can be measured.

[0023] The second method involves first installing the electromagnetic actuator to be tested in place, that is, placing the armature on the positioning shaft 7 and clamping the electromagnetic coil with the chuck 3. Then, the electromagnetic coil is energized, and the armature is attracted to the electromagnetic coil. The lead screw mechanism drives the guide mechanism to move forward until the guide mechanism brings the force gauge 1 and the telescopic component 2 to the support mechanism. The lead screw mechanism continues to drive the guide mechanism to move forward. Since the length of the telescopic component 2 is slightly longer than that of the force gauge 1, as the guide mechanism moves forward, the telescopic component 2 first presses against the armature and then retracts until the force gauge 1 and the telescopic component 2 are on the same horizontal line. The force gauge 1 and the telescopic component 2 press against the armature at the same time until the armature attracted by the electromagnetic coil is reset. At this time, the electromagnetic force on the armature can be measured.
