Description

Technical Field

[0001] This invention relates to the field of motor base technology, specifically to a shock-absorbing base for an industrial motor. Background Technology

[0002] Industrial motors, as the core power source in industrial systems, are electrical devices that efficiently convert electrical energy into mechanical energy, playing an irreplaceable role in every stage of industrial production. Whether it's machine tool processing and assembly line conveying in factories, material handling in mines, or fluid mixing in the chemical industry, all rely on the drive of industrial motors. These motors are categorized into various types, such as asynchronous motors and synchronous motors, depending on the application scenario. They possess advantages such as low energy consumption, stable operation, and strong adaptability, enabling them to operate continuously in high-temperature, high-load, and dusty industrial environments. They are key equipment driving industrial automation and large-scale production.

[0003] However, industrial motors inevitably vibrate during high-speed operation. This vibration not only affects the motor's own operating accuracy and lifespan but can also be transmitted to surrounding equipment, causing resonance, excessive noise, and even impacting the stability of the entire production line. To address this issue, vibration damping bases have been developed. As specialized support components for industrial motors, they effectively absorb the vibration energy generated by the motor's operation, buffer vibration impacts, and firmly fix the motor's position to prevent displacement deviations. This creates a stable operating environment for industrial motors, making them an indispensable and crucial accessory in industrial motor installation.

[0004] While existing industrial motor bases can effectively reduce vibration during operation, they lack mechanisms for adjusting the motor's height. Furthermore, the varying installation spaces for different equipment limit their applicability to diverse scenarios and needs, thus limiting their usability and adaptability. Therefore, we propose a new vibration-damping base for industrial motors. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a vibration damping base for industrial motors, thereby solving the problems mentioned in the background regarding the limited application range and adaptability of existing vibration damping bases.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shock-absorbing base for an industrial motor, comprising a shock-absorbing component, an adjustment component, and a reinforcement component. The shock-absorbing component includes a mounting base, a limit frame is fixedly mounted on the top of the mounting base, a shock-absorbing spring is sleeved on the outer wall of the limit frame, the top of the shock-absorbing spring abuts against a support frame, and a mounting plate is fixedly connected to the top of the support frame by bolts and nuts. The top of the mounting plate is provided with a motor body. The adjustment assembly includes a bracket, a motor is fixedly mounted on the outer wall of the bracket, a synchronous pulley is fixedly mounted on the output shaft of the motor, a synchronous belt is engaged on the outer wall of the synchronous pulley, a double-ended lead screw is fixedly mounted on the side wall of the synchronous pulley near the mounting base, a slider is threadedly connected to the outer wall of the double-ended lead screw, a rotating rod is rotatably connected to the top of the slider, a support plate fixedly mounted on the bottom of the mounting base is rotatably connected to the top of the rotating rod, and telescopic corrugated protective sleeves are provided on both sides of the slider. The adjustment assembly also includes a sliding groove formed on the top of the mounting base. The reinforcement assembly includes a support plate fixedly mounted on the top of the mounting base. A rotating frame is rotatably connected to the support plate near the side wall of the mounting base. A second limiting rod is fixedly mounted on the top of the rotating frame. A reinforcement rod is provided between the support plate and the support plate. A waist hole is provided on the outer wall of the reinforcement rod. A first limiting rod is fixedly mounted on the bottom of the rotating frame. The reinforcement assembly also includes a second waist hole opened on the outer wall of the support plate.

[0007] Through the above technical solution, by setting adjustment components, motor, synchronous pulley, synchronous belt, slider, rotating rod, support plate, and slide groove structure, when the operator installs the motor body, the double-headed lead screw can be rotated by the operation of the motor, thereby causing the two sliders to move in opposite directions, thus adjusting the height of the mounting plate to adapt to various installation scenarios and usage requirements, thereby achieving the effect of adapting to multiple application scenarios, and thus improving the application range and adaptability of the base.

[0008] Preferably, the end of the telescopic corrugated protective sleeve away from the slider is connected to the inner wall of the slide groove, and there are two sliders, both of which are symmetrically distributed along the outer wall of the double-ended lead screw.

[0009] Through the above technical solution, the two slider structures enable the shock-absorbing base to rotate the rotating rod by moving the sliders during use, thereby automatically adjusting the installation height of the mounting plate and the motor body. This facilitates user operation and improves the practicality of the shock-absorbing base.

[0010] Preferably, the number of the limiting brackets is four, and the four limiting brackets are evenly distributed along the top of the mounting base.

[0011] Through the above technical solution, the four limiting brackets are designed to support the mounting plate during use, and the elasticity of the damping springs is used to counteract the vibration force generated by the motor body during operation, thereby optimizing the damping effect of the base and improving its damping performance.

[0012] Preferably, the bottom of the support frame has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the limiting frame.

[0013] Through the above technical solution, the through hole and limiting frame structure allow the slider to move and the support frame to rise and fall during use. The limiting frame, in conjunction with the through hole, limits the movement of the support frame, ensuring that the support frame can only move vertically. This reduces the chance of the support frame tilting during adjustment and ensures the normal use of the shock-absorbing base.

[0014] Preferably, both ends of the reinforcing rod are rotatably connected to round rods, one end of which is rotatably connected to the side wall of the support plate near the mounting base, and the other end of which is slidably connected to the inner wall of the second waist hole.

[0015] Through the above technical solution, the structure of the round rod and support plate allows the support frame to rotate during the application of the shock-absorbing base. The lifting of the support frame also drives the reinforcing rod to rotate. In conjunction with the linkage of the rotating frame and the sliding of the round rod, the support frame can be supported by the rotating frame and the reinforcing rod in the initial state and after descent. This strengthens the tightness and contact area of ​​the connection structure between the support frame and the mounting base, thereby improving the stability of the shock-absorbing base during use.

[0016] Preferably, there is a gap of cm between the side wall of the reinforcing rod near the mounting base and the side wall of the support plate away from the mounting base, and the support plate, the rotating frame and the reinforcing rod are all made of galvanized iron.

[0017] Through the above technical solution, galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the probability of deformation or even breakage of the support plate and rotating frame during operation. This ensures the support effect of the support plate, rotating frame and reinforcing rod on the support frame during the support process, and can further reduce the wear of the three during operation, thereby extending the service life of the three.

[0018] Preferably, there are two rotating rods, the length of the two rotating rods is half that of the reinforcing rod, and the two rotating rods and the reinforcing rod are symmetrically distributed about the midpoint of the double-ended screw.

[0019] Through the above technical solution, by adjusting the length ratio between the rotating rod and the reinforcing rod, the lever arm of the reinforcing rod is longer than that of the rotating rod during operation. This causes the rotating rod to first lift the support plate during rotation, and the lifting of the support plate causes the contact point between the reinforcing rod and the support plate to move. This achieves the effect of adjustable support frame height and auxiliary support from the reinforcing components, further ensuring the normal use of the shock-absorbing base.

[0020] Preferably, the outer wall of the slider is slidably connected to the inner wall of the groove, the outer wall of the rotating frame is provided with a fixing hole, and the support plate is fixedly fitted with a positioning rod near the side wall of the mounting base, and the end of the positioning rod is rotatably connected to the inner wall of the fixing hole.

[0021] Through the above technical solution, the fixed hole and positioning rod structure allows the movement of the slider to drive the rotating frame to rotate during the operation of the shock-absorbing base. The positioning rod can be connected to the fixed hole to position the rotating frame, thereby allowing the angle of both ends of the rotating frame to be adjusted. This reduces the probability of the rotating frame becoming loose or even detaching during rotation, and thus reduces the probability of the subsequent use of the shock-absorbing base being affected.

[0022] Preferably, the bottom of the tray is provided with a connecting groove, and the inner wall of the connecting groove is rotatably connected to the top of the rotating rod.

[0023] Through the above technical solution, the connecting groove and rotating rod structure allow the rotating rod to have ample room to move during the movement of the slider, thereby increasing the adjustment range of the angle between the rotating rod and the support plate. This increases the lifting space of the support frame and further improves the adaptability and application range of the shock-absorbing base.

[0024] Compared with the prior art, the present invention provides a shock-absorbing base for an industrial motor, which has the following beneficial effects: 1. The vibration damping base of this industrial motor, through the setting of a mounting base, limit frame, vibration damping spring, support frame, mounting plate, motor, synchronous pulley, double-ended lead screw, and slider structure, allows the user to move the slider laterally through the operation of the motor during use. This causes the rotating rod to rotate and drive the support frame to rise and fall, thereby achieving the effect of adjusting the installation space of the motor body. It is suitable for various installation scenarios and usage needs, thus improving the application range and adaptability of the mounting base.

[0025] 2. The vibration damping base of this industrial motor, through the setting of reinforcement components, rotating frame, limit rod one, reinforcement rod, waist hole one, and waist hole two structure, enables the vibration damping base to use reinforcement components to provide auxiliary support for the support frame in the initial state and after adjustment during use, thereby effectively reducing the probability of deformation of the vibration damping base during use, thereby improving the compressive strength of the vibration damping base and thus improving the stability of the vibration damping base.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: like Figure 1-7 As shown, the present invention provides a shock-absorbing base for an industrial motor, including a shock-absorbing component 1, an adjustment component 2, and a reinforcement component 3. The shock-absorbing component 1 includes a mounting base 101, a limit frame 102 fixedly mounted on the top of the mounting base 101, a shock-absorbing spring 103 sleeved on the outer wall of the limit frame 102, a support frame 104 abutting the top of the shock-absorbing spring 103, and a mounting plate 105 fixedly connected to the top of the support frame 104 by bolts and nuts. The motor body 106 is provided on the top of the mounting plate 105. The adjustment assembly 2 includes a bracket, a motor 201 is fixedly mounted on the outer wall of the bracket, a synchronous pulley 202 is fixedly mounted on the output shaft of the motor 201, a synchronous belt 203 is engaged on the outer wall of the synchronous pulley 202, a double-ended lead screw 208 is fixedly mounted on the side wall of the synchronous pulley 202 near the mounting base 101, a slider 204 is threadedly connected to the outer wall of the double-ended lead screw 208, a rotating rod 205 is rotatably connected to the top of the slider 204, a support plate 206 fixedly mounted on the bottom of the mounting base 101 is rotatably connected to the top of the rotating rod 205, and a telescopic corrugated protective sleeve 209 is provided on both sides of the slider 204. The adjustment assembly 2 also includes a slide groove 207 opened on the top of the mounting base 101. The reinforcement component 3 includes a support plate 301 fixedly mounted on the top of the mounting base 101. A rotating frame 302 is rotatably connected to the support plate 301 near the side wall of the mounting base 101. A limit rod 307 is fixedly mounted on the top of the rotating frame 302. A reinforcement rod 304 is provided between the support plate 301 and the support plate 206. A waist hole 305 is provided on the outer wall of the reinforcement rod 304. A limit rod 303 is fixedly mounted on the bottom of the rotating frame 302. The reinforcement component 3 also includes a waist hole 306 opened on the outer wall of the support plate 206.

[0030] The advantage is that, through the structure of the adjustment component 2, motor 201, synchronous pulley 202, synchronous belt 203, slider 204, rotating rod 205, support plate 206, and slide groove 207, when the operator installs the motor body 106, the double-headed lead screw 208 can be rotated by the operation of the motor 201, thereby causing the two sliders 204 to move in opposite directions. This adjusts the height of the mounting plate 105 to adapt to various installation scenarios and usage requirements, thus achieving the effect of adapting to various application scenarios and improving the application range and adaptability of the base.

[0031] Specifically: the end of the telescopic corrugated protective sleeve 209 away from the slider 204 is connected to the inner wall of the slide groove 207. There are two sliders 204, and both sliders 204 are symmetrically distributed along the outer wall of the double-ended lead screw 208.

[0032] The advantage is that, through the structure of the two sliders 204, the vibration damping base can rotate the rotating rod 205 by moving the sliders 204 during use, thereby achieving the effect of automatically adjusting the installation height of the mounting plate 105 and the motor body 106, which facilitates user operation and improves the practicality of the vibration damping base.

[0033] Specifically, there are four limit brackets 102, and all four limit brackets 102 are evenly distributed along the top of the mounting base 101.

[0034] The advantage is that, through the structure of the four limiting brackets 102, the shock-absorbing base supports the mounting plate 105 during use, and the elasticity of the shock-absorbing spring 103 counteracts the vibration force generated by the motor body 106 during operation, thereby optimizing the shock absorption effect of the base and improving the shock absorption effect of the base.

[0035] Specifically: the bottom of the support frame 104 has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the limiting frame 102.

[0036] The advantage is that, through the through hole and the limiting bracket 102 structure, the movement of the slider 204 during the use of the shock-absorbing base can cause the support frame 104 to rise and fall. This allows the limiting bracket 102 to work with the through hole to limit the movement of the support frame 104, thus ensuring that the support frame 104 can only move vertically. This reduces the probability of the support frame 104 tilting during adjustment, thereby ensuring the normal use of the shock-absorbing base.

[0037] Example 2: like Figure 3-7 As shown, this is an improvement on the previous embodiment.

[0038] Specifically: Both ends of the reinforcing rod 304 are rotatably connected to round rods. The end of one round rod is rotatably connected to the side wall of the support plate 301 near the mounting base 101, and the end of the other round rod is slidably connected to the inner wall of the second waist hole 306.

[0039] The advantage is that, through the structure of the round rod and the support plate 301, the lifting and lowering of the support frame 104 during the application of the shock-absorbing base will also drive the reinforcing rod 304 to rotate. In conjunction with the linkage of the rotating frame 302 and the sliding of the round rod, the support frame 104 can be supported by the rotating frame 302 and the reinforcing rod 304 in the initial state and after lowering. This strengthens the tightness and contact area of ​​the connection structure between the support frame 104 and the mounting base 101, thereby improving the stability of the shock-absorbing base during use.

[0040] Specifically: there is a 1cm gap between the side wall of the reinforcing rod 304 near the mounting base 101 and the side wall of the support plate 206 away from the mounting base 101, and the support plate 301, the rotating frame 302 and the reinforcing rod 304 are all made of galvanized iron.

[0041] The advantage is that galvanized iron has the characteristics of hardness and wear resistance, which can effectively reduce the probability of deformation or even breakage of support plate 301 and rotating frame 302 during operation, thereby ensuring the support effect of support plate 301, rotating frame 302 and reinforcing rod 304 on support frame 104 during support, and further reducing wear of the three during operation, thus extending the service life of the three.

[0042] Specifically: There are two rotating rods 205, the length of which is half that of the reinforcing rod 304, and both rotating rods 205 and reinforcing rod 304 are symmetrically distributed with the midpoint of the double-ended screw 208 as the axis.

[0043] The advantage is that, through the length ratio between the rotating rod 205 and the reinforcing rod 304, the lever arm of the reinforcing rod 304 is longer than that of the rotating rod 205 during operation. This causes the rotating rod 205 to first drive the support plate 206 to rise and fall during rotation. The rising and falling of the support plate 206 causes the contact point between the reinforcing rod 304 and the support plate 206 to move, thereby achieving the effect that the height of the support frame 104 is adjustable and the reinforcing component 3 can provide auxiliary support for the support frame 104, further ensuring the normal use of the shock-absorbing base.

[0044] Specifically: the outer wall of the slider 204 is slidably connected to the inner wall of the slide groove 207, the outer wall of the rotating frame 302 is provided with a fixing hole, and the support plate 301 is fixedly fitted with a positioning rod near the side wall of the mounting base 101, and the end of the positioning rod is rotatably connected to the inner wall of the fixing hole.

[0045] The advantage is that, through the structure of the fixed hole and the positioning rod, the movement of the slider 204 during the operation of the shock-absorbing base will cause the rotating frame 302 to rotate. The positioning rod can be connected to the fixed hole to position the rotating frame 302, thereby allowing the two ends of the rotating frame 302 to be angled, reducing the probability of the rotating frame 302 becoming loose or even detached during rotation, and thus reducing the probability of the subsequent use of the shock-absorbing base being affected.

[0046] Specifically: The bottom of the tray 206 is provided with a connecting groove, and the inner wall of the connecting groove is rotatably connected to the top of the rotating rod 205.

[0047] The advantage is that, through the structure of the connecting groove and the rotating rod 205, the rotating rod 205 has sufficient room to move during the movement of the slider 204, thereby increasing the adjustment range of the angle between the rotating rod 205 and the support plate 206, thus increasing the lifting space of the support frame 104, and further improving the adaptability and application range of the shock-absorbing base.

[0048] Working principle: When using the shock absorber base, the operator first drives the synchronous pulley 202 to rotate via the motor 201. The synchronous pulley 202, in conjunction with the synchronous belt 203, rotates synchronously, causing the two double-ended lead screws 208 to rotate and drive the two sets of sliders 204 to move in opposite directions. At this time, the support frame 104 slides upwards along the outer wall of the limit frame 102 and rises; conversely, it lowers. This allows the operator to easily adjust the installation space of the motor body 106, adapting to various installation scenarios and usage requirements, thereby improving the applicability and suitability of the shock absorber base. In addition, during the movement of the slider 204, the rotation of the rotating rod 205 will drive the rotating frame 302 to rotate synchronously, so that the limiting rod 303 and the round rod at the end of the rotating frame 302 and the reinforcing rod 304 slide along the inner wall of the first waist hole 305 and the second waist hole 306 respectively. During this process, the gap between the support plate 206 and the reinforcing rod 304 can ensure the normal lifting and lowering of the support frame 104. At the same time, the support frame 104 will also be reinforced by the reinforcing rod 304 and the rotating frame 302, reducing the probability of the shock-absorbing base bending or even deforming due to load, thereby improving the stability of the shock-absorbing base during use.

[0049] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
