Abstract
Description
Technical Field
[0001] The invention relates to the technical field of magnetic attraction tooling, and more specifically to a threaded magnetic attraction tooling. Background Art
[0002] In order to improve the response speed and fuel economy of the wet high-pressure dual clutch, a high-pressure wet dual clutch was developed. Structurally different from the traditional clutch, the EOL test bench test of the high-pressure wet dual clutch requires the working pressure of the piston to be increased from 15bar-20bar to 32bar-42bar compared to the traditional clutch design, and at the same time requires the leakage of the internal pressure oil of the piston to be zero when the piston is working. Therefore, the interference between the piston and the cylinder of the high-pressure wet clutch has increased from the original 0.3mm to more than 0.8mm. This change has created new challenges for the rapid and efficient testing of the test bench. The existing EOL test bench can be reused 1:1 and the CSC of the oil circuit position can be changed during the test to achieve efficient and rapid testing. Among them, checking the residual iron filings on the thread after the test is completed is a key research content.
[0003] At present, when detecting the iron filings in the clutch thread, after the clutch is tested on the EOL test bench, the employee needs to manually move the clutch after unscrewing the CSC base and place it on the inspection bench for testing. For example, the prior art publication number CN118464325B is an experimental device for testing the performance of an automobile clutch. This prior art can use the compressed air in the clutch to flush and clean the annular tube after the airtightness test of the clutch through the control component, remove impurities in the annular tube, and improve the test accuracy.
[0004] However, the above-mentioned prior art still has the following problems when in use: the clutch is rotated under the light of the inspection bench to check whether there are iron filings on the thread. If there are iron filings, tweezers are needed to pick them up, and sometimes it is impossible to accurately locate and clamp them. This step process increases the labor intensity of the workers and is not conducive to improving the production efficiency of the enterprise. Based on this, the present invention provides a thread magnetic suction tool that automatically positions and magnetically absorbs iron filings and has high production efficiency.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] Refer to the instruction manual Figure 1-8 The present invention provides a threaded magnetic suction tool, including a positioning base 1, which is used to place a clutch to be tested. With the help of the positioning holes on the positioning base 1, the staff can quickly and accurately place the clutch to a fixed position to achieve accurate suction; The magnetic attraction component 2 is used to clean the iron filings in the clutch thread. The magnetic attraction component 2 includes an electromagnet 201. Specifically, the electromagnet 201 is a device that uses electric current to generate a strong magnetic field. It is usually composed of an iron core, a coil and a power supply. When powered on, the electromagnet will generate a magnetic field and adsorb the attracted material (such as iron filings) on its surface. The model of the electromagnet 201 can be DO3257. The electromagnet 201 is set to be cylindrical, and the top of the electromagnet 201 is detachably connected with a connecting column 202; The top of the connecting column 202 is connected to a rotating assembly 203 for driving the connecting column 202 to rotate. Specifically, the rotating assembly 203 includes a servo motor 2031. Specifically, the servo motor 2031 is a motor that can accurately control position, speed and acceleration. Its model can be MR-J4. The bottom end of the output shaft of the servo motor 2031 is detachably connected to the top of the connecting column 202. The servo motor 2031 is detachably installed on the top of the connecting member 303 through a mounting frame 2032. The servo motor 2031 is used to drive the electromagnet 201 to rotate automatically, so that the electromagnet 201 absorbs iron filings while rotating, thereby improving the cleaning effect of the iron filings and also improving the magnetic attraction efficiency. The bottom end of the electromagnet 201 extends out of the bottom of the connecting piece 303, and the connecting column 202 is rotatably connected to the top of the connecting piece 303. The connecting piece 303 supports the electromagnet 201 and the connecting column 202, which can improve the stability of the electromagnet 201. The lifting assembly 3 is used to drive the electromagnet 201 to move up and down. The lifting assembly 3 includes a lifting rail 301 installed on the top of the positioning base 1, and the lifting rail 301 is located behind the clutch. A slider 302 is sleeved on the lifting rail 301. The electromagnet 201 is connected to the front end of the slider 302 through a connecting piece 303; The lifting assembly 3 also includes a linear module 304. Specifically, the linear module 304 is a linear motion device, mainly composed of a motor, a screw rod or a synchronous belt, a slider, a lifting guide rail, and a mounting seat. The model of the linear module 304 can be RSA-ST12. The front end of the linear module 304 is detachably connected to the rear end of the slider 302. The linear module 304 cooperates with the lifting guide rail 301 to stably lift the electromagnet 201 and prevent the electromagnet 201 from damaging the clutch thread. Handles 6 are fixedly provided on both sides of the top of the positioning base 1. A plurality of mounting holes 7 are evenly processed on the top of the positioning base 1. In actual use, a plurality of bolts can be used to pass through the plurality of mounting holes 7 respectively, thereby improving the stability of the positioning base 1.
[0019] When in use, the staff first places the clutch after being tested by the EOL test bench on the positioning base 1, and then uses the linear module 304 to drive the slider 302 to slide downward on the lifting guide rail 301. The slider 302 drives the electromagnet 201, the connecting column 202 and the servo motor 2031 to move downward together through the connecting piece 303. When the cylindrical electromagnet 201 moves to the center point of the clutch thread, the servo motor 2031 is started to drive the connecting column 202 and the electromagnet 201 to rotate. The electromagnet 201 absorbs the iron filings on the clutch thread while rotating, thereby completing the precise absorption of the iron filings on the clutch thread, which can not only prevent the iron filings from remaining in the clutch thread and affecting the normal use of the clutch, but also play the role of detecting the iron filings. This embodiment can accurately position the product through the cooperation of the positioning base 1, the magnetic suction component 2, the rotating component 203 and the lifting component 3, thereby achieving fast and efficient positioning. The lifting component 3 and the rotating component 203 are used to efficiently position and absorb the iron filings, and then the originally complex and time-consuming quality inspection work can be quickly completed, greatly improving the working efficiency and quality of the clutch.
[0020] Refer to the instruction manual Figure 1 , 3 and Figure 6-7 The bottom end of the linear module 304 is fixed with an electric turntable 305 for driving the linear module 304 to rotate. Specifically, the electric turntable 305 is a common mechanical device, mainly used to rotate various objects or workpieces. Its model may be JXA-85-05-N. The electric turntable 305 is fixed on the top of the positioning base 1. The electric turntable 305 can automatically adjust the height of the electromagnet 201. Two handles 6 are distributed on both sides of the electric turntable 305. It also includes a cleaning component 4 for cleaning iron filings on the electromagnet 201. The cleaning component 4 includes an iron ring plate 401 and a collection box 402. The iron ring plate 401 is sleeved on the outside of the electromagnet 201. The collection box 402 is detachably mounted on the top of the positioning base 1, and the collection box 402 is located behind the linear module 304 to collect iron filings, so that subsequent staff can centrally handle them. An electric push rod 403 is fixedly passed through the center of the rear end of the collection box 402. Specifically, the electric push rod 403 is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. Its model may be ANT-26. An electric clamp 404 is fixedly provided at the front end of the piston rod of the electric push rod 403. Specifically, the electric clamp 404 is a device that uses electric drive to achieve clamping and loosening operations on the workpiece. It provides power through a motor and transmits the power to the clamping part of the clamp through a transmission mechanism, thereby completing the fixation of the iron ring plate 401. Its model may be JXSA304B. Positioning grooves 5 are provided on both sides of the top of the positioning base 1. The bottoms of both sides of the collection box 402 are respectively inserted into the two positioning grooves 5. The positioning grooves 5 are used to assist in the installation of the collection box 402, thereby improving the efficiency of installing the collection box 402.
[0021] By also arranging a collecting component on the positioning base 1, after long-term use, the electric turntable 305 is first used to drive the magnetic suction component 2 and the lifting component 3 to rotate 180 degrees, so that the electromagnet 201 is turned into the collecting box 402, and the electric turntable 305 and the electromagnet 201 are turned off. At this time, the electromagnet 201 loses its magnetism, and some iron filings can automatically fall into the collecting box 402. Then, the electric push rod 403 is used to drive the electric clamp 404 to move forward to the rear side of the iron ring plate 401, and then the linear module 304 is used to drive the electric clamp 404 to move forward to the rear side of the iron ring plate 401. The electromagnet 201 moves down to a position close to the electric clamp 404, and then the electric clamp 404 is used to firmly clamp the iron ring plate 401. Then the linear module 304 is used to drive the electromagnet 201 to move up. At this time, the iron ring plate 401 is stationary. The electromagnet 201 uses the iron ring plate 401 to completely scrape the iron filings on the surface into the collection box 402, thereby realizing automatic cleaning of the electromagnet 201, avoiding manual cleaning that causes iron filings to remain and affect subsequent quality inspection work, and at the same time can also improve work efficiency.
[0022] And in actual use, a control box can be installed on the positioning base 1 to control the operation of the linear module 304 and the electric turntable 305 of the present invention, and a battery for providing electrical energy is arranged inside the control box. The electromagnet 201, the servo motor 2031 and the electric push rod 403 are powered by their own batteries. In order to facilitate the control box to control the electromagnet 201, the servo motor 2031 and the electric push rod 403, all three can be connected to the control box through a wireless transmission module. The above technologies are all existing commonly used technologies and will not be further elaborated here.
