Description

Technical Field

[0001] This utility model relates to the field of headframe motor technology, specifically a headframe motor with a shock-absorbing base. Background Technology

[0002] Headframe motors, as key power output components, are widely used in numerous mechanical devices. However, traditional headframe motors generate vibration during operation, which not only affects the motor's own lifespan but also negatively impacts the stability and precision of the entire equipment.

[0003] In the prior art, utility model patent application number 202122460718.7 discloses a floor-mounted spring shock absorber for mechanical vibration reduction, including a base plate. The top of the base plate is integrally formed with a lower seat, and the inner wall of the lower seat is vulcanized and bonded with a rubber baffle. A guide groove is formed in the middle of the rubber baffle and the lower seat plate. A guide block slides into the guide groove, and the outer wall of the guide block is vulcanized and bonded with a rubber baffle. The guide block is welded to the outer wall of the upper seat, and the top of the upper seat is integrally formed with a top plate. A fixing cover is fixedly connected to the middle of the bottom end of the top plate, and a spring is interference-fitted between the bottom end of the fixing cover and the base plate. Support seats are set at both ends of the top of the base plate. When the mechanical equipment presses the top plate downward, the bottom column below the top plate presses the rubber plug in the column groove of the support seat to perform frictional force relief. By increasing the damping force relief structure of the shock absorber, the damping force relief capacity of the shock absorber is improved.

[0004] Existing mechanical vibration damping systems, such as floor-mounted spring dampers, can be installed on the feet of the headframe motor to serve as a vibration damping base for the headframe motor and provide it with vibration damping capabilities.

[0005] However, when using the existing mechanical vibration damping floor-mounted spring damper as the vibration damping base for the head frame motor, there is a lack of a structure for a stable installation between the vibration damping base and the head frame motor. Directly placing the head frame motor on the vibration damping base can easily cause lateral movement between the two, resulting in the head frame motor falling off the vibration damping base. Utility Model Content

[0006] The purpose of this invention is to provide a headframe motor with a shock-absorbing base to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a headframe motor with a shock-absorbing base, comprising: a headframe motor and a shock-absorbing base top plate, wherein a stud hole is formed on the surface of the headframe motor, a stud is fixed at the top of the shock-absorbing base top plate, the stud is movably inserted into the stud hole, a nut is installed on the surface of the stud by a threaded connection, an anti-loosening plate mounting groove is formed at the top of the headframe motor, one end of an anti-loosening plate is movably inserted into the anti-loosening plate mounting groove, and the other end of the anti-loosening plate is sleeved on the surface of the nut.

[0008] Preferably, the anti-loosening plate has a ring-shaped structure, and the inner ring shape of the anti-loosening plate matches the nut.

[0009] Preferably, a plurality of anti-loosening springs are fixed at one end of the anti-loosening plate that extends into the anti-loosening plate mounting groove, the bottom ends of the plurality of anti-loosening springs are fixed on the inner wall of the bottom end of the anti-loosening plate mounting groove, and the plurality of anti-loosening springs are arranged in a circular array about the axis of the stud.

[0010] Preferably, a washer is fitted on the rod of the stud, with one end of the washer abutting against the top of the head frame motor and the other end of the washer abutting against the bottom of the nut.

[0011] Preferably, a rubber pad is fixed to the bottom end of the head frame motor, and the bottom end of the rubber pad abuts against the top end of the shock-absorbing base plate.

[0012] Preferably, a limit rod mounting seat is fixed to the top of the head frame motor, and a limit rod is movably inserted into the surface of the limit rod mounting seat.

[0013] Preferably, the top of the limiting rod mounting base is provided with a lever window, and a lever is slidably connected in the lever window. One end of the lever is fixed to the top of the limiting rod, and the other end of the lever extends out of the lever window.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model proposes a headframe motor with a shock-absorbing base. A stud passes through a stud hole on the surface of the headframe motor. A washer is then fitted onto the stud's shaft. Next, an anti-loosening plate is pressed downwards until it is fully retracted into the anti-loosening plate mounting groove, compressing the anti-loosening spring. A nut is then tightened onto the stud via a threaded connection. After basic tightening, the nut is finely adjusted in the tightening direction until it aligns with the inner ring of the anti-loosening plate. The anti-loosening plate is then released, and the anti-loosening spring, under its own elasticity, pushes one end of the anti-loosening plate out of the mounting groove, allowing it to fit onto the nut and provide circumferential restraint. This achieves the threaded anti-loosening function between the nut and the stud, ensuring the headframe motor is securely mounted on the top of the shock-absorbing base plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 3 This utility model provides a technical solution: a headframe motor with a shock-absorbing base, comprising: a headframe motor 1 and a shock-absorbing base top plate 2. A stud hole 3 is formed on the surface of the headframe motor 1. A stud 4 is fixed to the top of the shock-absorbing base top plate 2, and the stud 4 is movably inserted into the stud hole 3. A nut 5 is threadedly installed on the surface of the stud 4. An anti-loosening plate mounting groove 7 is formed at the top of the headframe motor 1, and one end of an anti-loosening plate 8 is movably inserted into the anti-loosening plate mounting groove 7. The other end of the anti-loosening plate 8... The anti-loosening plate 8 is a ring-shaped plate structure fitted onto the surface of the nut 5. The inner ring shape of the anti-loosening plate 8 matches the nut 5. A washer 6 is fitted onto the rod of the stud 4. One end of the washer 6 abuts against the top of the head frame motor 1, and the other end of the washer 6 abuts against the bottom of the nut 5. Several sets of anti-loosening springs 9 are fixed to one end of the anti-loosening plate 8 that extends into the anti-loosening plate mounting groove 7. The bottom ends of the several sets of anti-loosening springs 9 are fixed to the inner wall of the bottom end of the anti-loosening plate mounting groove 7. The several sets of anti-loosening springs 9 are arranged in a circular array about the axis of the stud 4.

[0022] In practical use, the existing mechanical vibration damping floor-mounted spring damper can be installed at the bottom of the headframe motor to serve as a vibration damping base for the headframe motor. During the manufacturing of the vibration damping base, a fixing stud 4 is welded to the top of the top plate 2 of the vibration damping base. During installation, the stud 4 passes through the stud hole 3 on the surface of the headframe motor 1. Then, a washer 6 is fitted onto the rod of the stud 4. Afterward, the anti-loosening plate 8 is pressed downward so that it is completely retracted into the anti-loosening plate mounting groove 7. This compresses the anti-loosening spring 9. Then... Tighten the nut 5 onto the stud 4 via the threaded connection. After it is basically tightened, continue to fine-tune the nut 5 in the tightening direction so that the nut 5 is aligned with the inner ring of the anti-loosening plate 8. Then loosen the anti-loosening plate 8. Under its own elasticity, the anti-loosening spring 9 pushes one end of the anti-loosening plate 8 out of the anti-loosening plate mounting groove 7, so that one end of the anti-loosening plate 8 is fitted onto the nut 5 to circumferentially limit the nut 5. This realizes the thread anti-loosening function between the nut 5 and the stud 4, so that the head frame motor 1 is firmly installed on the top of the shock-absorbing base plate 2.

[0023] Example 2: Based on Example 1, in order to reduce the impact force between the head frame motor 1 and the top plate of the shock-absorbing base 2, a rubber pad 14 is fixed to the bottom end of the head frame motor 1, and the bottom end of the rubber pad 14 abuts against the top end of the top plate of the shock-absorbing base 2.

[0024] The head frame motor 1 will generate a large vibration during operation. The vibration of the head frame motor 1 will cause the head frame motor 1 to collide with the top plate of the shock-absorbing base 2. In order to reduce this impact force, a rubber pad 14 is fixed at the bottom of the head frame motor 1. The rubber pad 14 plays a buffering role against the impact force of the head frame motor 1, thereby reducing the impact force between the head frame motor 1 and the top plate of the shock-absorbing base 2.

[0025] Example 3: Based on Example 2, in order to keep the anti-loosening plate 8 fully retracted in the anti-loosening plate mounting groove 7 when the nut 5 is disassembled and assembled, a limit rod mounting seat 10 is fixed to the top of the head frame motor 1. A limit rod 11 is movably inserted into the surface of the limit rod mounting seat 10. A lever window 12 is opened at the top of the limit rod mounting seat 10. A lever 13 is slidably connected in the lever window 12. One end of the lever 13 is fixed to the top of the limit rod 11, and the other end of the lever 13 extends out of the lever window 12.

[0026] When installing or removing nut 5, manually press the anti-loosening plate 8 completely into the anti-loosening plate mounting groove 7, then move lever 13 so that lever 13 moves towards the anti-loosening plate 8 in lever window 12. Lever 13 drives limit rod 11 to move in the same direction, so that one end of limit rod 11 extends from the surface of limit rod mounting seat 10 and abuts against the top of anti-loosening plate 8. Then the anti-loosening plate 8 can be kept fully retracted in the anti-loosening plate mounting groove 7 without having to press it by hand.

[0027] In practical use, the existing mechanical vibration damping floor-mounted spring damper can be installed at the bottom of the headframe motor to serve as a vibration damping base for the headframe motor. During the manufacturing of the vibration damping base, a fixing stud 4 is welded to the top of the top plate 2. During installation, the stud 4 passes through the stud hole 3 on the surface of the headframe motor 1. A washer 6 is then fitted onto the rod of the stud 4. Next, the anti-loosening plate 8 is pressed down until it is fully retracted into the anti-loosening plate mounting groove 7, compressing the anti-loosening spring 9. Then, the nut 5 is tightened onto the stud 4 via a threaded connection. After basic tightening, the nut 5 is finely adjusted in the tightening direction until it aligns with the inner ring of the anti-loosening plate 8. The anti-loosening plate 8 is then released, and the anti-loosening spring 9, under its own elasticity, pushes one end of the anti-loosening plate 8 out of the anti-loosening plate mounting groove 7, allowing one end of the anti-loosening plate 8 to fit onto the nut 5, providing circumferential restraint to the nut 5. This achieves threaded connection between the nut 5 and the stud 4. The anti-loosening function ensures that the head frame motor 1 is securely mounted on the top of the shock-absorbing base plate 2. During operation, the head frame motor 1 generates significant vibration, which can cause impact between it and the shock-absorbing base plate 2. To reduce this impact force, a rubber pad 14 is fixed to the bottom of the head frame motor 1. The rubber pad 14 cushions the impact force, thus reducing the impact force between the head frame motor 1 and the shock-absorbing base plate 2. When installing or removing the nut 5, manually press the anti-loosening plate 8 completely into the anti-loosening plate mounting groove 7, then move the lever 13. This causes the lever 13 to move towards the anti-loosening plate 8 through the lever window 12. The lever 13 drives the limiting rod 11 to move in the same direction, causing one end of the limiting rod 11 to extend from the surface of the limiting rod mounting seat 10 and abut against the top of the anti-loosening plate 8. This keeps the anti-loosening plate 8 fully retracted into the anti-loosening plate mounting groove 7 without requiring continuous manual pressing.

[0028] 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.
