Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining center technology, and in particular to a shock-absorbing vertical machining center. Background Technology
[0002] A machining center is a highly automated, multi-functional CNC machine tool equipped with a tool magazine and automatic tool changer. A vertical machining center refers to a machining center whose spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and small shells. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting. However, this type of equipment generates significant vertical vibration during machining, which not only produces considerable noise and causes sound pollution, affecting machining accuracy and equipment stability, but also damages internal components of the vertical machining center over time, reducing their service life. Therefore, vibration dampers need to be installed.
[0003] While existing vertical machining centers can buffer and reduce vibration through high-pressure springs and damping blocks, the damping blocks will wear down during long-term use, especially the upper damping blocks, which wear more severely than the lower damping blocks. However, the damping blocks need to be replaced as a whole, which undoubtedly increases the maintenance cost of the equipment and leads to unnecessary waste of parts and economic expenditure.
[0004] Therefore, there is an urgent need to provide a vibration-damping vertical machining center to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a shock-absorbing vertical machining center.
[0006] To solve the above-mentioned technical problems, the present invention provides a shock-absorbing vertical machining center, including a vertical machining center body, base plates fixedly installed on both sides of the vertical machining center body, a sound-insulating friction pad fixedly installed on the top of the base plate, an installation mechanism provided at the bottom of the base plate, a support mechanism provided at the bottom of the installation mechanism, and a damping mechanism provided inside the installation mechanism and the support mechanism.
[0007] The present invention is further configured such that: the mounting mechanism includes a fixing bolt threaded inside the base plate, a fixing nut is threaded on the outer surface of the fixing bolt, and an adjusting nut is threaded on the outer surface of the fixing bolt.
[0008] The above technical solution uses a fixing bolt and a fixing nut to connect to the base plate via a threaded connection, and a sound-insulating friction pad isolates the fixing nut from contact with the base plate.
[0009] The present invention is further configured such that: a pressure cap is threaded on the outer surface of the fixing bolt, and four lifting square tubes are fixedly installed at the bottom end of the pressure cap.
[0010] With the above technical solution, the fixing bolt adjusts the distance between the pressure cap and the base plate by adjusting the nut, and the pressure cap drives the lifting square tube to rise and fall.
[0011] The present invention is further configured such that: the support mechanism includes a support base disposed below the lifting square tube, a rubber anti-slip pad is fixedly installed at the bottom end of the support base, and a fixed square tube is fixedly installed at the top end of the support base.
[0012] Through the above technical solution, the support base supports the vertical machining center body, and the rubber anti-slip pad increases the friction between the support base and the ground.
[0013] The present invention is further configured such that: an installation square column is fixedly installed on the inner bottom wall of the fixed square tube, a lower rubber pad is fixedly installed on the top of the support base, and an upper rubber pad is threaded on the outer surface of the fixing bolt.
[0014] With the above technical solution, when the fixing bolt drives the upper rubber pad to descend, the upper rubber pad buffers and reduces shock through the lower rubber pad.
[0015] The present invention is further configured such that: the damping mechanism includes a shock-absorbing spring fixed to the bottom end of the pressure cover, and a spring anti-slip pad is fixedly installed at the bottom end of the shock-absorbing spring.
[0016] Through the above technical solutions, the shock-absorbing springs and spring anti-slip pads absorb and mitigate the vibration and impact force transmitted by the vertical machining center body through their own elastic deformation.
[0017] The present invention is further configured such that: a first damping pad is fitted into the inner wall of the fixed square tube, a second damping pad is fitted into the outer side of the mounting square column, a square tube top cover is fitted into the top of the fixed square tube, and a top cover screw with one end penetrating and extending into the interior of the fixed square tube is threaded onto both sides of the square tube top cover.
[0018] Through the above technical solution, the lifting square tube reduces the vibration speed of the shock-absorbing spring through the first damping pad and the second damping pad, so that the vibration of the system can be attenuated more quickly. The top of the square tube is fixed to the top of the first damping pad, and the top of the top is fixed to the square tube top and the fixed square tube by the top screw.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. This utility model has a support mechanism and a damping mechanism. The damping pad slows down the vibration speed of the spring, so that the vibration of the system can decay faster. The damping pad has a multi-layer structure, and only the damping pad with severe wear needs to be replaced. This undoubtedly reduces the maintenance cost of the equipment and reduces unnecessary waste of parts and economic expenditure.
[0021] 2. By providing an installation mechanism and a support mechanism, this utility model enables the high-pressure spring to absorb and mitigate axial vibrations or instantaneous impacts during the operation of the machining center, thereby reducing the impact of vibrations on machining accuracy and the equipment itself.

Detailed Implementation
[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0029] Please see Figures 1-5A vibration-damping vertical machining center includes a vertical machining center body 1. Base plates 2 are fixedly mounted on both sides of the vertical machining center body 1. A sound-insulating friction pad 3 is fixedly mounted on the top of the base plate 2. A mounting mechanism 4 is provided at the bottom of the base plate 2. The mounting mechanism 4 includes a fixing bolt 401 threaded inside the base plate 2, a fixing nut 402 threaded on the outer surface of the fixing bolt 401, and an adjusting nut 403 threaded on the outer surface of the fixing bolt 401. The pressure cover 404 is equipped with four lifting square tubes 405 fixedly installed at the bottom end of the pressure cover 404. The pressure cover 404 is threadedly connected to the base plate 2 by fixing bolts 401 and fixing nuts 402. The sound insulation friction pad 3 isolates the contact between the fixing nuts 402 and the base plate 2. The fixing bolts 401 adjust the distance between the pressure cover 404 and the base plate 2 by adjusting nuts 403. The vibration and impact force of the vertical machining center body 1 are transmitted to the pressure cover 404 through the fixing bolts 401, so that the pressure cover 404 drives the lifting square tubes 405 to rise and fall.
[0030] like Figures 3-5 As shown, a support mechanism 5 is provided at the bottom of the installation mechanism 4. The support mechanism 5 includes a support base 501 located below the lifting square tube 405. A rubber anti-slip pad 502 is fixedly installed at the bottom of the support base 501. A fixed square tube 503 is fixedly installed at the top of the support base 501. An installation square column 504 is fixedly installed on the inner bottom wall of the fixed square tube 503. A lower rubber pad 505 is fixedly installed at the top of the support base 501. An upper rubber pad 506 is threaded on the outer surface of the fixing bolt 401. The support base 501 supports the vertical machining center body 1. The rubber anti-slip pad 502 increases the friction between the support base 501 and the ground. When the fixing bolt 401 drives the upper rubber pad 506 to descend, the upper rubber pad 506 buffers and reduces shock through the lower rubber pad 505.
[0031] like Figure 4 and Figure 5As shown, the mounting mechanism 4 and the support mechanism 5 are internally equipped with a damping mechanism 6. The damping mechanism 6 includes a shock-absorbing spring 601 fixed to the bottom end of the pressure cover 404. A spring anti-slip pad 602 is fixedly installed at the bottom end of the shock-absorbing spring 601. A first damping pad 603 is fitted into the inner wall of the fixed square tube 503. A second damping pad 604 is fitted into the outer side of the mounting square column 504. A square tube top cover 605 is fitted into the top end of the fixed square tube 503. Both sides of the square tube top cover 605 are threaded with a through end extending to the fixed square tube. The top bracket screw 606, shock-absorbing spring 601, and spring anti-slip pad 602 inside tube 503 absorb and mitigate the vibration and impact force transmitted by the vertical machining center body 1 through their own elastic deformation. The lifting square tube 405 reduces the vibration speed of the shock-absorbing spring 601 through the first damping pad 603 and the second damping pad 604, so that the vibration of the system can decay more quickly. The square tube top bracket 605 fixes the top of the first damping pad 603, and the top bracket screw 606 fixes the square tube top bracket 605 and the fixed square tube 503.
[0032] In use, this utility model is threadedly connected to the base plate 2 via fixing bolts 401 and fixing nuts 402. Sound-insulating friction pads 3 isolate the fixing nuts 402 from contact with the base plate 2. The fixing bolts 401 adjust the distance between the pressure cap 404 and the base plate 2 via adjusting nuts 403. A square tube top cover 605 fixes the top of the first damping pad 603. Top cover screws 606 fix the square tube top cover 605 and the fixed square tube 503. The support base 501 supports the vertical machining center body 1. Rubber anti-slip pads 502 increase the friction between the support base 501 and the ground. In use, the vibration and impact force of the vertical machining center body 1 are transmitted to the pressure plate 404 through the fixing bolt 401, causing the pressure plate 404 to drive the lifting square tube 405 to rise and fall. The shock-absorbing spring 601 and the spring anti-slip pad 602 absorb and alleviate the vibration and impact force transmitted by the vertical machining center body 1 through their own elastic deformation. The lifting square tube 405 slows down the vibration speed of the shock-absorbing spring 601 through the first damping pad 603 and the second damping pad 604, so that the vibration of the system can decay more quickly. When the fixing bolt 401 drives the upper rubber pad 506 to fall, the upper rubber pad 506 buffers and absorbs shock through the lower rubber pad 505.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
