Description

Technical Field

[0001] The utility model relates to the technical field of drilling and tapping equipment, in particular to a low-noise drilling and tapping machine. Background Art

[0002] A drilling and tapping machine is a metal cutting machine that uses a high-speed rotating cutting tool to cut the workpiece to achieve operations such as drilling and tapping. It usually uses a CNC numerical control system for precise processing. This type of machine tool equipment combines multiple functions such as drilling, tapping, and milling in one, and can be used in various industries, such as automobiles, aerospace, molds, electronics, etc. Due to its high precision, high efficiency and high stability, drilling and tapping machines are particularly important in the manufacturing industry and can meet the needs of batch processing of a variety of complex parts and molds.

[0003] In the prior art, drilling and tapping machines inevitably vibrate during operation, and the bottom collides with the ground to produce a loud noise. Working in a noisy environment for a long time may cause workers to suffer from hearing loss or even permanent hearing loss. Continuous noise will increase the psychological and physiological stress of workers, leading to reduced work efficiency and even health problems. Noise will affect the comfort of the working environment, may interfere with normal communication and operating procedures, and thus affect production efficiency. If the drilling and tapping machine frequently collides with the ground due to vibration, it may damage the structural stability of the machine tool, thereby reducing the service life of the equipment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a low-noise drilling and tapping machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a low-noise drilling and tapping machine, including a drilling and tapping main body, a bearing plate fixed at the bottom of the drilling and tapping main body, a sleeve column fixed at the bottom of the bearing plate, a buffer spring fixed at the top of the inner wall of the sleeve column, an inner column slidably connected to the inner wall of the sleeve column, one end of the buffer spring is fixed to the bottom of the inner wall of the inner column, a bottom bearing plate is fixed at the bottom of the inner column, a damping cylinder is fixed at the bottom of the bearing plate, a damping plate is slidably connected to the inner wall of the damping cylinder, a sliding column is fixed at the bottom of the damping plate, a limiting column is fixed at the bottom of the sliding column, and the bottom of the limiting column is fixed to the top of the bottom bearing plate. In the prior art, the drilling and tapping machine inevitably vibrates during operation, and the bottom collides with the ground to generate a large noise. Working in a noisy environment for a long time may cause hearing loss or even permanent hearing loss to the staff. Continuous noise will increase the psychological and physiological stress of the staff, leading to work Efficiency is reduced and even health problems may occur. Noise will affect the comfort of the working environment and may interfere with normal communication and operating procedures, thereby affecting production efficiency. If the drilling and tapping machine frequently collides with the ground due to vibration, it may damage the structural stability of the machine tool, thereby reducing the service life of the equipment. To address such problems, the utility model solves the problem by installing a sleeve column, so that when the equipment is running, the buffer spring absorbs vibration and converts it into elastic potential energy. The release of elastic potential energy limits the vibration to a specific range, reduces the vibration amplitude of the equipment, and increases the vibration frequency. At the same time, when the elastic potential energy is released, the sliding friction between the sleeve column and the inner column converts the elastic potential energy into internal energy, and the sliding friction between the damping cylinder and the damping plate also converts part of the elastic potential energy into internal energy, thereby greatly reducing the vibration frequency, stabilizing the equipment, and preventing the bottom of the equipment from colliding with the ground to generate noise, thereby reducing equipment noise, increasing equipment service life, and improving user experience.

[0006] Preferably, a mounting groove is provided at the bottom of the bottom support plate, and a rubber pad is fixed to the inner wall of the mounting groove. In the prior art, the bottom support plate is made of metal and often collides with the ground when vibrated, affecting the experience of the staff. Continuous noise will increase the psychological and physiological stress of the staff, resulting in reduced work efficiency. To solve such problems, the utility model adopts the method of installing rubber pads to achieve a solution, which realizes that the rubber pads can effectively absorb the vibrations generated by the machine during operation due to their good toughness and adjustable hardness. Reducing vibrations means reducing the noise caused by vibrations, thereby achieving the effect of reducing noise. The rubber material has certain sound insulation properties, which can reduce the noise propagation generated when the machine is in direct contact with the ground. By installing rubber pads at the bottom of the machine, it can isolate sound, prevent noise from spreading through the ground, reduce additional noise caused by machine movement or shaking, and improve processing accuracy and efficiency. At the same time, the support of the rubber pads can prevent the bottom support plate from deforming, thereby achieving the effect of reducing noise generation and increasing the service life of the equipment.

[0007] Preferably, a trapezoidal baffle is fixed on the top of the bottom support plate. In the prior art, when the shock absorbing device is in use, since it is close to the ground, some workers will put their feet on the bottom support plate. When the equipment vibrates, once the up and down movement is large, the workers' feet will be clamped, causing injuries to personnel, leading to production accidents and reducing production safety. To solve such problems, the utility model adopts the method of installing a trapezoidal baffle to achieve a solution, which realizes that the trapezoidal baffle can prevent the workers from putting their feet on the bottom support plate. Even if the workers put their feet on the trapezoidal baffle, since one side of the trapezoidal baffle is an inclined surface, the workers cannot maintain the action and their feet will slide down due to lack of force, thereby improving production safety and improving the user experience.

[0008] Preferably, a limiting rubber ring is fixed to the circumferential surface of the bottom end of the sleeve column, and the bottom surface height of the limiting rubber ring is smaller than the bottom surface height of the sleeve column. Once the sleeve column moves with a large amplitude, the limiting rubber ring will first contact the bottom support plate and perform buffering through its own deformation to avoid damage to the equipment and increase the service life of the equipment.

[0009] Preferably, the height of the sliding column is greater than the maximum compression length of the buffer spring, so as to protect the buffer spring and prevent the buffer spring from being subjected to excessive pressure, which would exceed its buffer limit and cause component damage, thereby increasing the service life of the equipment.

[0010] Preferably, a cross groove is provided at the bottom of the rubber pad, and the friction between the rubber pad and the ground is increased through the cross groove to prevent the device from being deflected due to vibration.

[0011] Preferably, the rubber pad is configured as a tetrahedral cube, and the contact area between the rubber pad and the ground is increased by the tetrahedral cube while the material remains unchanged, thereby reducing the production cost. Beneficial Effects

[0012] 1. In the prior art, drilling and tapping machines inevitably generate vibrations during operation, and the bottom collides with the ground to generate a large noise. Working in a noisy environment for a long time may cause hearing loss or even permanent hearing loss to the staff. Continuous noise will increase the psychological and physiological pressure of the staff, resulting in reduced work efficiency and even health problems. The noise will affect the comfort of the working environment, may interfere with normal communication and operation processes, and thus affect production efficiency. If the drilling and tapping machine frequently collides with the ground due to vibration, it may damage the structural stability of the machine tool, thereby reducing the service life of the equipment. In response to such problems, the utility model adopts the method of installing a sleeve column to solve the problem, so that when the equipment is running, the buffer spring absorbs the vibration and converts it into elastic potential energy. The release of the elastic potential energy limits the vibration within a specific range, reduces the vibration amplitude of the equipment, and increases the vibration frequency. At the same time, when the elastic potential energy is released, the sliding friction between the sleeve column and the inner column converts the elastic potential energy into internal energy, and the sliding friction between the damping cylinder and the damping plate also converts part of the elastic potential energy into internal energy, thereby greatly reducing the vibration frequency, stabilizing the equipment, and preventing the bottom of the equipment from colliding with the ground to generate noise, thereby achieving the effect of reducing equipment noise, increasing equipment service life, and improving user experience.

[0013] 2. In the prior art, the bottom plate is made of metal, which often collides with the ground when vibrated, affecting the experience of the staff. The continuous noise will increase the psychological and physiological pressure of the staff, resulting in reduced work efficiency. In response to such problems, the utility model solves this problem by installing rubber pads. The rubber pads can effectively absorb the vibrations generated by the machine during operation due to their good toughness and adjustable hardness. Reducing vibrations means reducing the noise caused by vibrations, thereby achieving the effect of reducing noise. The rubber material has certain sound insulation properties, which can reduce the noise propagation generated when the machine is in direct contact with the ground. By installing rubber pads at the bottom of the machine, it can isolate the sound, prevent the noise from spreading through the ground, reduce the additional noise caused by the movement or shaking of the machine, and improve the processing accuracy and efficiency. At the same time, the support of the rubber pads can prevent the deformation of the bottom plate, thereby reducing the noise generation and increasing the service life of the equipment.

[0014] 3. In the prior art, when the shock absorbing device is in use, since it is close to the ground, some workers will put their feet on the bottom support plate. When the equipment vibrates, once the up and down movement is large, the workers' feet will be clamped, causing injuries to personnel, leading to production accidents and reducing production safety. To solve this problem, the utility model adopts the method of installing a trapezoidal block to achieve a solution, which realizes that the trapezoidal block can prevent the workers from putting their feet on the bottom support plate. Even if the workers put their feet on the trapezoidal block, since one side of the trapezoidal block is an inclined surface, the workers cannot keep the action and their feet will slide down due to lack of force, thereby improving production safety and achieving the effect of improving user experience.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiments

[0023] Reference Figure 1-4, a low-noise drilling and tapping machine comprises a drilling and tapping body 1, a bearing plate 2 is fixed to the bottom of the drilling and tapping body 1, a sleeve column 201 is fixed to the bottom of the bearing plate 2, a buffer spring 203 is fixed to the top of the inner wall of the sleeve column 201, an inner column 202 is slidably connected to the inner wall of the sleeve column 201, one end of the buffer spring 203 is fixed to the bottom of the inner wall of the inner column 202, a bottom supporting plate 204 is fixed to the bottom of the inner column 202, a damping cylinder 3 is fixed to the bottom of the bearing plate 2, a damping plate 301 is slidably connected to the inner wall of the damping cylinder 3, a sliding column 302 is fixed to the bottom of the damping plate 301, a limiting column 303 is fixed to the bottom of the sliding column 302, and the bottom of the limiting column 303 is fixed to the top of the bottom supporting plate 204. The drilling and tapping machine will inevitably vibrate during operation, and the bottom will collide with the ground to generate a large noise. Working in a noisy environment for a long time may cause hearing loss or even permanent hearing loss to the staff. Continuous noise will increase the psychological and physiological pressure of the staff, leading to work Efficiency is reduced and even health problems may occur. Noise will affect the comfort of the working environment and may interfere with normal communication and operating procedures, thereby affecting production efficiency. If the drilling and tapping machine frequently collides with the ground due to vibration, it may damage the structural stability of the machine tool, thereby reducing the service life of the equipment. The problem is solved by installing a sleeve column 201. When the equipment is running, the buffer spring 203 absorbs the vibration and converts it into elastic potential energy. The release of elastic potential energy limits the vibration to a specific range, reduces the vibration amplitude of the equipment, and increases the vibration frequency. At the same time, when the elastic potential energy is released, the sliding friction between the sleeve column 201 and the inner column 202 converts the elastic potential energy into internal energy, and the sliding friction between the damping cylinder 3 and the damping plate 301 also converts part of the elastic potential energy into internal energy, thereby greatly reducing the vibration frequency, stabilizing the equipment, and preventing the bottom of the equipment from colliding with the ground to generate noise, thereby reducing equipment noise, increasing equipment service life, and improving user experience. A limiting rubber ring 205 is fixed to the circumference of the bottom end of the sleeve 201. The bottom height of the limiting rubber ring 205 is less than the bottom height of the sleeve 201. Once the sleeve 201 moves with a large amplitude, the limiting rubber ring 205 will first contact the bottom support plate 204, and buffer through its own deformation to avoid damage to the equipment and increase the service life of the equipment. The height of the sliding column 302 is greater than the maximum compression length of the buffer spring 203, which protects the buffer spring 203 and prevents the buffer spring 203 from being subjected to excessive pressure, resulting in damage to the components due to exceeding its buffer limit, thereby increasing the service life of the equipment.

[0024] The bottom of the bottom plate 204 is provided with a mounting groove 4, and a rubber pad 401 is fixed on the inner wall of the mounting groove 4. The bottom plate 204 is made of metal, and when it is vibrated, it often collides with the ground, affecting the experience of the staff. The continuous noise will increase the psychological and physiological pressure of the staff, resulting in reduced work efficiency. The rubber pad 401 is installed to solve the problem. The rubber pad 401 can effectively absorb the vibration generated by the machine during operation due to its good toughness and adjustable hardness. Reducing vibration means reducing the noise caused by vibration, thereby achieving the effect of reducing noise. The rubber material has a certain sound insulation performance, which can reduce the noise propagation generated when the machine is in direct contact with the ground. By installing the rubber pad 401 at the bottom of the machine, it can isolate the sound, prevent the noise from spreading through the ground, reduce the additional noise caused by the movement or shaking of the machine, and improve the processing accuracy and efficiency. At the same time, the support of the rubber pad 401 can prevent the bottom plate 204 from deforming, thereby reducing the noise generation and increasing the service life of the equipment. A cross groove 402 is provided at the bottom of the rubber pad 401, and the cross groove 402 is used to increase the friction between the rubber pad 401 and the ground, so as to prevent the equipment from being deflected by vibration. The rubber pad 401 is set as a quadrangular pyramid cube, and the contact area between the rubber pad 401 and the ground is increased by the quadrangular pyramid under the condition that the material remains unchanged, thereby reducing the production cost. A trapezoidal stopper 5 is fixed on the top of the bottom support plate 204. When the shock absorbing device is in use, some staff members will put their feet on the bottom support plate 204 because it is close to the ground. When the equipment vibrates, once the up and down movement amplitude is large, the staff members' feet will be clamped, causing injuries to personnel, leading to the occurrence of production accidents, and reducing production safety. The trapezoidal stopper 5 is installed to solve the problem, so that the trapezoidal stopper 5 can prevent the staff members from putting their feet on the bottom support plate 204. Even if the staff members put their feet on the trapezoidal stopper 5, since one side of the trapezoidal stopper 5 is an inclined surface, the staff members cannot save the action, and the feet will slide down without force, thereby improving production safety and achieving the effect of improving user experience.

[0025] The working principle of the utility model is as follows: when the equipment is running, the buffer spring 203 absorbs vibration and converts it into elastic potential energy. The release of the elastic potential energy limits the vibration within a specific range, reduces the vibration amplitude of the equipment, and increases the vibration frequency. At the same time, when the elastic potential energy is released, the sliding friction between the sleeve column 201 and the inner column 202 converts the elastic potential energy into internal energy, and the sliding friction between the damping cylinder 3 and the damping plate 301 also converts part of the elastic potential energy into internal energy, thereby greatly reducing the vibration frequency, stabilizing the equipment, and preventing the bottom of the equipment from colliding with the ground to generate noise.
