Description

Technical Field

[0001] The present invention relates to the technical field of machining centers, and more particularly to a machining center for machining metal accessories. Background Art

[0002] In modern manufacturing, metal parts processing is a vital link. As a highly automated and multifunctional metal processing equipment, machining centers are widely used in many fields such as aerospace, automobile manufacturing, and mechanical equipment. Through precise CNC programming, it can realize milling, drilling, boring and other processing operations on various metal materials, and efficiently produce metal parts that meet high-precision requirements.

[0003] In the process of metal parts processing, a large amount of cutting fluid is usually used to cool and lubricate the tool and flush away the chips. The cutting fluid is generally applied to the processing area by high-pressure injection or spraying around the tool. However, due to the high-speed rotation of the tool, the effect of cutting force and the complex shape of the workpiece during processing, the cutting fluid and chips are very easy to splash around. Once they come into contact with the observation window of the machining center, they are easy to adhere to its surface, forming a layer of liquid film or water droplets of condensation.

[0004] However, currently, when many observation windows are contaminated, they are cleaned manually by wiping, that is, operators are arranged to use clean rags, scrapers and other tools to manually remove cutting fluid and debris on the observation windows when the machining center is suspended or in a short idle time. Frequent manual wiping will take up a lot of production time, thereby affecting the processing efficiency of metal accessories. We propose a machining center for machining metal accessories. Summary of the invention

[0005] The purpose of the present invention is to provide a machining center for machining metal accessories, aiming to solve the problem that the observation window of the existing machining center is cleaned by manual wiping after being contaminated, thereby increasing the labor intensity of the staff and reducing the machining efficiency.

[0007] Preferably, both side end walls inside the fixed box are rotatably connected with an adjustment disk, and the outer walls of the adjustment disk are provided with adjustment grooves passing through the adjustment disk. Both side end walls outside the adjustment box are fixedly connected with guide pillars, and the other ends of the guide pillars extend into the adjustment grooves respectively, and the adjustment grooves are arc-shaped structures. The outer walls of the adjustment disk are symmetrically recessed inwardly so that their outer walls form a protruding abutting portion, and the outer wall of the abutting portion abuts against the inner wall of the U-shaped frame.

[0008] Preferably, a semicircular limiting groove is provided on the outer wall of the adjusting disk, and a rubber limiting column is provided on the inner wall of the fixing box, and the limiting column is located in the limiting groove.

[0009] Preferably, a pair of elastic members are fixedly connected to the inner wall of the fixing box, and the ends of the elastic members are rotatably connected to the limiting posts respectively. The elastic members push the limiting posts to abut against the inner wall of the limiting groove under their own elastic force.

[0010] Preferably, both ends of the scraper are respectively inclined downward, and the scraper forms an "eight"-shaped structure after being inclined.

[0011] Preferably, both sides of the scraper are curled upward to form a blocking portion, and the blocking portion is a semicircular structure.

[0012] Preferably, the outer walls of the connecting plates are respectively provided with debris discharge openings corresponding to the blocking portions, and the debris discharge openings all penetrate the connecting plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a machining center body, an observation window, a U-shaped frame, a transmission disk, a window groove, a ball screw, a fixing box and a cleaning mechanism, so that when a worker opens the observation window to remove the processed metal accessories, the transmission disk drives the fixing box to move back and forth up and down through the ball screw, so that the fixing box cleans the contaminated inner wall of the observation window through the cleaning mechanism while moving up and down, so that the worker does not need to clean the observation window specially, thereby increasing the processing efficiency of metal accessories and reducing the labor intensity of the worker.

[0014] 2. In the present invention, the connecting plate is connected to the adjustment box through a spring, so that the connecting plate itself can squeeze the spring to generate twisting, and when the scraper contacts the observation window and moves up with the connecting plate, the friction force generated between the scraper and the observation window will be transmitted to the connecting plate, so that the connecting plate drives the scraper to tilt together, thereby increasing the cleaning effect of the inclined scraper on the observation window, and the scraper presses against the observation window under the elastic force of the spring, so that the scraping effect of the scraper on the observation window is increased.

[0015] 3. The present invention provides an adjusting disk so that the adjusting disk can twist back and forth as the fixed box moves up and down, so that the adjusting disk pulls and pushes the guide column through the adjusting groove, so that the guide column drives the adjusting box to move, so that when the adjusting box moves up, the scraper is driven to fit the observation window, and when the adjusting box moves down, the scraper is driven away from the observation window, so that the scraper is no longer in contact with the observation window, so that the movement direction of the scraper strip for cleaning is single, and the friction mode between its edge and the observation window is relatively stable, and it is not easy to cause irregular wear of the scraper strip edge due to frequent reversing, thereby reducing the possibility of scratches on the surface of the observation window, and is more conducive to protecting the smoothness of the surface of the observation window, and the scraper strip does not have a returning action like reciprocating scraping, so the scraped stains will be continuously taken away from the cleaned area as the scraper strip moves unidirectionally, reducing the probability of the stains re-attaching to the cleaned observation window surface.

[0016] 4. In the present invention, both ends of the scraper bar are respectively tilted downward to form an "eight"-shaped structure, so that when the scraper bar is tilted upward to scrape the surface of the observation window, the inclined part of the scraper bar will guide the chips and cutting fluid cleaned from the observation window, thereby preventing the chips and cutting fluid from accumulating in one place on the scraper bar, preventing the chips from scratching the observation window, and preventing the accumulated chips and cutting fluid from affecting the cleaning effect of the scraper bar.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] by Figures 1 to 6 As shown, a machining center for machining metal accessories includes a machining center body 1 and an observation window 2, a U-shaped frame 3 is fixedly connected to a side of the observation window 2 close to the interior of the machining center body 1, a pair of transmission disks 4 are rotatably connected to the bottom inner wall of the U-shaped frame 3, a pair of window grooves 5 corresponding to the transmission disks 4 are formed on the outer wall of the observation window 2, the outer wall of the transmission disk 4 extends through the window grooves 5 and abuts against the inner wall of the machining center body 1, a pair of ball screws 6 are fixedly connected to the top of the transmission disk 4, a fixing box 7 is detachably connected between the sliders of the ball screw 6, and a cleaning mechanism for cleaning the observation window 2 is also provided in the fixing box 7.

[0021] Among them, the cleaning mechanism includes an adjusting box 8 arranged inside the fixed box 7, the adjusting box 8 is a U-shaped structure, and a plurality of springs 9 are fixedly connected to the inner surface of the adjusting box 8, and the other end of the spring 9 is fixedly connected to a connecting plate 10, and a pair of rubber scrapers 11 are fixedly connected to the side of the connecting plate 10 close to the observation window 2, and the other side of the scraper 11 is in contact with the inner wall of the observation window 2 under the elastic force of the spring 9.

[0022] Specifically, after the machining center body 1 completes the processing of metal accessories, the staff opens the observation window 2. During the movement of the observation window 2, the transmission disk 4 is driven to move together, and the outer wall of the transmission disk 4 abuts against the inner wall of the machining center body 1, which causes the transmission disk 4 to start to rotate. The rotation of the transmission disk 4 drives the ball screw 6 to rotate, so that when the ball screw 6 rotates, it drives the fixed box 7 to move through its own slider. As the observation window 2 is opened and closed, the rotation direction of the transmission disk 4 is different, thereby realizing the up and down reciprocating movement of the fixed box 7.

[0023] Since the fixed box 7 will drive the adjusting box 8 to move when it moves, and the movement of the adjusting box 8 will drive the connecting plate 10 to move through the spring 9 fixedly connected thereto, so that the connecting plate 10 drives the scraper 11 to move when it moves, and the scraper 11 fits with the observation window 2 under the elastic force of the spring 9, which makes the scraper 11 scrape and clean the chips and cutting fluid stuck on the observation window 2 during the movement, so that the staff does not need to specially clean the observation window 2, thereby increasing the processing efficiency of metal accessories and reducing the labor intensity of the staff.

[0024] Furthermore, both side end walls inside the fixed box 7 are rotatably connected with an adjusting disk 12, and the outer wall of the adjusting disk 12 is provided with an adjusting groove 13 passing through it, and both side end walls outside the adjusting box 8 are fixedly connected with guide pillars 14, and the other ends of the guide pillars 14 extend into the adjusting grooves 13 respectively, and the adjusting grooves 13 are arc-shaped structures, and the outer wall of the adjusting disk 12 is symmetrically recessed inwardly so that its outer wall forms a protruding abutting portion 15, and the outer wall of the abutting portion 15 abuts against the inner wall of the U-shaped frame 3.

[0025] Specifically, when the fixed box 7 moves, it will drive the adjusting disk 12 to move together, and the abutting portion 15 formed on the adjusting disk 12 will contact the inner wall of the U-shaped frame 3 when it moves, and start to rotate due to the friction force generated by the contact therewith. It should be noted that since the abutting portion 15 is obtained by the outer wall of the adjusting disk 12 being symmetrically recessed inward, when the adjusting disk 12 rotates, its recessed portion will correspond to the inner wall of the U-shaped frame 3, making it impossible for the adjusting disk 12 to rotate. When the adjusting disk 12 moves in the opposite direction, the abutting portion 15 on the adjusting disk 12 will contact the U-shaped frame 3 again to reverse it, so that when the adjusting disk 12 rotates, it pulls and pushes the guide column 14 through the adjusting groove 13 of the arc structure, so that the guide column 14 The column 14 drives the adjustment box 8 to move, so that when the adjustment box 8 moves up, it drives the scraper 11 to fit with the observation window 2; and when the adjustment box 8 moves down, it drives the scraper 11 away from the observation window 2, so that the scraper 11 no longer contacts the observation window 2, so that the movement direction of the scraper strip for cleaning is single, and the friction mode between its edge and the observation window 2 is relatively stable, and it is not easy to cause irregular wear of the scraper strip edge due to frequent reversing, thereby reducing the possibility of scratches on the surface of the observation window 2, and is more conducive to protecting the smoothness of the surface of the observation window 2. The scraper strip will not have a returning action like reciprocating scraping, so the scraped stains will be continuously taken away from the cleaned area as the scraper strip moves unidirectionally, reducing the probability of stains re-attaching to the cleaned surface of the observation window 2.

[0026] Furthermore, a semicircular limit groove 16 is provided on the outer wall of the adjusting disk 12, and a rubber limit column 17 is provided on the inner wall of the fixing box 7, and the limit column 17 is located in the limit groove 16; the limit column 17 is provided to clamp the limit groove 16, thereby increasing the stability of the adjusting disk 12 after the scraper 11 is fitted with the observation window 2 when it rotates, and because the limit column 17 is made of rubber, the limit column 17 can be forced to be squeezed and disengaged from the limit groove 16 as the adjusting disk 12 rotates, so that the guide column 14 will not affect the rotation of the adjusting disk 12.

[0027] A pair of elastic members 18 are fixedly connected to the inner wall of the fixed box 7, and the ends of the elastic members 18 are rotatably connected to the limit posts 17 respectively. The elastic members 18 push the limit posts 17 to abut against the inner wall of the limit groove 16 under their own elastic force; through the provision of the elastic members 18, the limit posts 17 are snapped into the limit grooves 16 under the elastic force of the elastic members 18, thereby increasing the stability of the adjusting disk 12, and the adjusting disk 12 can also squeeze the limit posts 17 when it is rotated under force, so that the limit posts 17 refuel the elastic members 18 and twist and simultaneously pull out of the limit grooves 16, thereby making it possible for the adjusting disk 12 to rotate without forcibly squeezing the limit posts 17, thereby preventing the limit posts 17 from being damaged.

[0028] Furthermore, the two ends of the scraper 11 are respectively tilted downward, and the scraper 11 forms an "eight"-shaped structure after being tilted; the two ends of the scraper strip are respectively tilted downward to form an "eight"-shaped structure, so that when the scraper strip is tilted and scraped upward on the surface of the observation window 2, the inclined part of the scraper strip will guide the chips and cutting fluid cleaned from the observation window 2, thereby preventing the chips and cutting fluid from accumulating in one place on the scraper strip, preventing the chips from scratching the observation window 2, and preventing the accumulated chips and cutting fluid from affecting the cleaning effect of the scraper strip.

[0029] The two sides of the scraper 11 are curled upward to form a blocking portion 19, and the blocking portion 19 is a semicircular structure; specifically, the blocking portion 19 formed by the two sides of the scraper 11 curling upward can block the chips and cutting fluid cleaned by the scraper 11, thereby preventing the chips and cutting fluid from sliding from the two ends of the scraper 11 and re-adhering to the observation window 2.

[0030] The outer walls of the connecting plate 10 are respectively provided with debris discharge openings 20 corresponding to the blocking portion 19, and the debris discharge openings 20 all penetrate the connecting plate 10; specifically, the debris discharge openings 20 opened on the connecting plate 10 correspond to the blocking portion 19, so that the chips and cutting fluid in the blocking portion 19 can enter the fixed box 7 through the debris discharge openings 20, and the fixed box 7 is detachable, thereby facilitating the recovery of the cleaned chips and cutting fluid.

[0031] Working principle: This embodiment provides a processing center for processing metal accessories. After the processing center body 1 processes metal accessories, the staff opens the observation window 2. The observation window 2 will drive the transmission disk 4 to move together during the movement, and the outer wall of the transmission disk 4 abuts against the inner wall of the processing center body 1, which makes the transmission disk 4 start to rotate, and the rotation of the transmission disk 4 will drive the ball screw 6 to rotate, so that when the ball screw 6 rotates, it drives the fixed box 7 to move through its own slider, and with the opening and closing of the observation window 2, the rotation direction of the transmission disk 4 is different, so as to realize the up and down reciprocating movement of the fixed box 7; When the fixed box 7 moves, it will drive the adjusting box 8 to move together. The movement of the adjusting box 8 will drive the connecting plate 10 to move together through the spring 9 fixedly connected thereto, so that the connecting plate 10 drives the scraper 11 to move when it moves. The scraper 11 fits with the observation window 2 under the elastic force of the spring 9, which makes the scraper 11 scrape and clean the chips and cutting fluid stuck on the observation window 2 during the movement, so that the staff does not need to specially clean the observation window 2, thereby increasing the processing efficiency of metal accessories and reducing the labor intensity of the staff.

[0032] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
