Description

Technical Field

[0001] The present invention relates to a parts cutting device, in particular to a high-precision mechanical parts cutting device applied to the field of parts processing. Background Art

[0002] In the production and processing of high-precision parts, especially in the process of laser processing parts, it is particularly important to maintain the stability of the workpiece. For example, in the laser cutting process with high processing accuracy requirements, if the workpiece jitter exceeds a certain amplitude, it may cause inaccurate cutting lines, resulting in defective products, increased workpiece loss rate, and increased product costs.

[0003] To solve the above problems, the Chinese patent CN218284154U specification discloses a high-precision laser cutting machine, including a base and a laser cutting module and a workpiece clamping module installed on the base. The cutting part of the laser cutting module is arranged above the workpiece clamping module and can move along the cutting path. One end of the workpiece clamping module is a fixed end and the other end is a slidable driving end. The fixed end and the driving end of the workpiece clamping module are respectively tightly matched with two sides of the workpiece. The high-precision laser cutting machine can stably position the workpiece, has a good anti-shake effect, and improves the precision of part cutting processing.

[0004] In the prior art, the lower part of the laser cutting machine is generally provided with a placement rack for placing the workpiece to be cut. The placement rack is mainly composed of a plurality of long strips with triangular protrusions, which are used to support the workpiece to be cut. However, since some cutting machines in the laser cutting machine realize cutting by liquefying the cutting part of the workpiece and blowing away the liquefied melt with gas, a lot of slag is usually attached to the placement rack after cutting. In the prior art, the slag is also cleaned manually within a certain period of time (after multiple processing). However, due to untimely cleaning, the attached slag may cause the workpiece to be cut to be unstable or tilted at the placement angle, thereby resulting in reduced precision of the workpiece after cutting, waste, defective products, etc., and reduced qualified rate of finished products.

[0051] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0052] The first implementation method:

[0053] The present invention provides a high-precision mechanical parts cutting device, see Figure 1-Figure 3 , including a cutting machine base 100 and a top base 300, a placement frame 400 is fixedly mounted on the cutting machine base 100, and a movable laser cutting head 200 is mounted at the lower end of the top base 300;

[0054] When cutting is required, the laser cutting head 200 is controlled by the controller to move freely in multiple directions on the top seat 300, and the workpiece to be cut placed on the placement rack 400 is laser cut. Laser cutting has many advantages such as good cutting quality, high cutting efficiency, fast cutting speed, non-contact cutting, and a wide variety of cutting materials, which can meet the cutting needs of high-precision mechanical parts;

[0055] A cleaning mechanism 500 is installed in the middle of the cutting machine base 100. The cleaning mechanism 500 includes a driving structure, a cleaning scraper 3 and an adaptive guide assembly 4:

[0056] The driving structure is used to drive the cleaning scraper 3 to be inserted and moved in sequence into the multiple gaps of the placement rack 400;

[0057] The height of the cleaning scraper 3 is greater than or equal to the height of the rack 400;

[0058] The adaptive guide assembly 4 is used to drive the cleaning scraper 3 to smoothly enter the gap of the placement rack 400 and ensure that the blade of the cleaning scraper 3 is in stable contact with the side wall of the placement rack 400;

[0059] A dust collecting mechanism is also installed in the middle of the cutting machine base 100, and the dust collecting mechanism is used to collect the slag scraped by the cleaning scraper 3.

[0060] Based on the above structure, after the cutting is completed, the cleaning scraper 3 is used to scrape the slag from the side walls of the rack body on both sides of the gap of the placement rack 400, so that the slag attached to the rack body of the placement rack 400 falls off and is finally collected by the dust collecting mechanism, which is conducive to cleaning the slag attached to the placement rack 400, making it easy to keep the placement rack 400 clean and tidy, and at the same time avoiding the placement stability and angle of the workpiece to be cut affected by the large amount of slag attached to the placement rack 400, improving the cutting accuracy during cutting, and avoiding the waste and defective products caused by slight changes in the placement angle of the workpiece to be cut or unstable placement;

[0061] The driving structure and the adaptive guiding assembly 4 can be used to drive the cleaning scraper 3 to move sequentially in multiple gaps of the placement rack 400, and can ensure that the blade of the cleaning scraper 3 always adheres to the side wall of the rack 400 during cleaning, thereby facilitating stable and effective cleaning of the slag in all gaps of the placement rack 400, thereby achieving the purpose of comprehensive cleaning.

[0062] Figure 3-Figure 5 The adaptive guidance assembly 4 is shown to include:

[0063] A fixed block 41, the fixed block 41 is fixedly connected to the driving structure and is driven by the driving structure to be inserted and moved in sequence into the multiple gaps of the placement rack 400;

[0064] The movable blocks 42 are provided with two movable blocks 42 and are respectively located at the front and rear sides of the fixed block 41. The movable blocks 42 are elastically connected to the fixed block 41 through an elastic connecting piece;

[0065] A guide cone wheel 43, two guide cone wheels 43 are provided and correspond to the two movable blocks 42 respectively. The upper end of the guide cone wheel 43 has the smallest diameter and forms a spherical top, and the lower end of the guide cone wheel 43 has the largest diameter and is rotatably connected to the upper surface of the movable block 42 through a rotating shaft;

[0066] There are also two cleaning scrapers 3 and they are symmetrically arranged along the fixed block 41. The two cleaning scrapers 3 are respectively fixed to the ends of the upper surfaces of the two movable blocks 42 away from the guide cone wheel 43;

[0067] The upper end of the guide cone wheel 43 is higher than the upper end of the cleaning scraper 3. When the lower end of the guide cone wheel 43 abuts against the inner wall of the gap of the placement rack 400, the blades of the two cleaning scrapers 3 are respectively attached to the opposite side walls of the gap of the placement rack 400.

[0068] The elastic connecting member includes a spring 44 and a guide rod 45. Two springs 44 are provided and are respectively fixed to the front and rear sides of the fixed block 41. Two guide rods 45 are also provided and one end away from the movable block 42 is fixed to the fixed block 41. The other ends of the two guide rods 45 slide through the two movable blocks 42 on one side close to the fixed block 41.

[0069] When the cleaning scraper 3 is located below the placement rack 400 and enters the gap of the placement rack 400 upward, the upper side wall of the guide cone wheel 43 first contacts the bottom of the frame body of the placement rack 400 and is squeezed by the bottom of the frame body of the placement rack 400, so that the two guide cone wheels 43 approach each other, thereby driving the two cleaning scrapers 3 to approach each other through the two movable blocks 42, and gradually making the lower ends of the two guide cone wheels 43 contact the frame body of the placement rack 400 during the rising process, so that the blades of the two cleaning scrapers 3 are finally attached to the inner side wall of the gap of the placement rack 400, thereby facilitating the adaptive adjustment of the distance between the two cleaning scrapers 3 to adapt to the gaps of the placement racks 400 of different sizes, and while facilitating the automatic entry of the cleaning scraper 3 into the gap of the placement rack 400, it can also improve the scope of application of the high-precision mechanical parts cutting device and enhance its practicality.

[0070] Figure 2 , Figure 3 , Figure 7 as well as Figure 8 The driving structure is shown to include a track plate 1 and a support slide column 2. A plurality of parallel slide rails 11 are provided on the upper surface of the track plate 1. The extension direction of the plurality of slide rails 11 is the same as the extension direction of the gap of the placement rack 400. The lower end of the support slide column 2 is made of an electric slider commonly used in the prior art and suitable for this embodiment, so as to meet the requirement that the support slide column 2 slides along the slide rail 11.

[0071] Every two adjacent slide rails 11 are connected via a connecting rail 12 disposed at the end of the slide rail 11, and two connecting rails 12 between three adjacent slide rails 11 are respectively disposed at both ends and respectively connect two adjacent slide rails 11;

[0072] The horizontal height of the inner bottom wall of the connecting rail 12 is lower than the horizontal height of the inner bottom wall of the slide rail 11, and the height difference is greater than the height of the rack body of the placement rack 400;

[0073] A smooth lifting slope 13 is provided at the connection point between the slide rail 11 and the connecting rail 12. The lifting slope 13 is an arc-shaped or linear plane or a plane combining the two.

[0074] The lower end of the support slide post 2 is slidably connected to the slide rail 11 , and the upper end of the support slide post 2 is fixed to the lower end of the fixing block 41 .

[0075] When the supporting slide column 2 slides in the slide rail 11, the supporting slide column 2 slides to one end of the slide rail 11 and then descends through the lifting slope 13 and enters the bottom of the connecting rail 12, thereby driving the cleaning scraper 3 and the adaptive guide component 4 at the upper end to descend, so that the cleaning scraper 3 and the adaptive guide component 4 are separated from the gap of the placement rack 400 (that is, the stopped state during cutting, which does not affect the progress of the cutting operation). Then, the supporting slide column 2 slides along the connecting rail 12 to the end of the other slide rail 11 and rises through another lifting slope 13. When rising, the cleaning scraper 3 and the adaptive guide component 4 are driven to rise synchronously and enter another gap of the placement rack 400. When continuing to slide along the slide rail 11, the side walls of the rack body on both sides of the gap of the placement rack 400 can be cleaned. In this way, the adaptive guide component 4 is used to achieve the effect of driving the cleaning scraper 3 to slide and clean in the gaps of multiple placement racks 400 in sequence, thereby realizing orderly cleaning of the entire placement rack 400.

[0076] Figure 4 and Fig. 9 It is shown that a plurality of vibration rods 9 evenly distributed along the frame of the placement rack 400 are fixed at the lower end of the frame;

[0077] A striking rod 421 is fixed to the side wall of the movable block 42 away from the fixed block 41 , and the striking rod 421 intersects vertically with the vibration rod 9 in a horizontal plane.

[0078] When the movable block 42 moves horizontally, it drives the striking rod 421 to move synchronously. When the striking rod 421 moves to vertically intersect the vibration rod 9, it hits the vibration rod 9, thereby causing the vibration rod 9 to vibrate and transmit the vibration force to the placement rack 400, thereby causing the placement rack 400 to vibrate, which is more conducive to the slag on the placement rack 400 to fall off and improve the cleaning effect.

[0079] Figure 3 and Figure 6 The dust collection mechanism shown includes:

[0080] The slag suction frame 5 is disposed below the adaptive guide assembly 4 and has an opening facing upward. The opening area of ​​the slag suction frame 5 is larger than the bottom area of ​​the adaptive guide assembly 4. One side of the slag suction frame 5 is connected to a suction pump 52 through a slag suction pipe 51;

[0081] The interception box 6 is used to intercept and collect the slag in the slag suction pipe 51 . The input port of the suction pump 52 is connected to the interception box 6 , and the interception box 6 is connected to the slag suction pipe 51 .

[0082] The slag scraped off by the cleaning scraper 3 enters the slag suction frame 5 when it falls, and the suction pump 52 sucks the slag in the slag suction frame 5 into the interception box 6 through the slag suction pipe 51, and is intercepted and collected by the interception box 6, thereby achieving the purpose of collecting the scraped slag and avoiding secondary pollution caused by the dispersion of the slag.

[0083] Figure 3 and Figure 6 It is shown that a booster pump 62 is installed on the upper end of the interception box 6, the input port of the booster pump 62 is connected to the output port of the suction pump 52, and the output port of the booster pump 62 is connected to a cleaning nozzle 63 through an air pipe 61. The cleaning nozzle 63 is located on the side of the fixed block 41 close to the cleaning scraper 3, and the horizontal height of the cleaning nozzle 63 is the same as the height of the bent surface on the frame of the placement rack 400.

[0084] By setting up the booster pump 62, the air pipe 61 and the cleaning nozzle 63, the air adsorbed by the suction pump 52 is input into the booster pump 62 for pressurization, and the pressurized air is transported to the cleaning nozzle 63 through the air pipe 61, and finally ejected from the cleaning nozzle 63. The ejected high-pressure gas can blow on the bent surface of the rack 400 to remove the slag attached to the bent surface of the rack 400, thereby using the airflow in combination with the cleaning scraper 3 to remove the slag, thereby further improving the cleaning effect.

[0085] Figure 8 It is shown that a slag drop hole 14 penetrating the track plate 1 is opened at the bottom of the connecting rail 12, and the width of the slag drop hole 14 is smaller than the width of the connecting rail 12 and the width of the supporting sliding column 2;

[0086] A slag collecting bucket 8 is fixed at the lower end of the track plate 1, and the lower end of the interception box 6 is connected to the slag collecting bucket 8 through a slag discharge pipe 7;

[0087] When the supporting slide column 2 slides in the slide rail 11, the slag in the slide rail 11 can be pushed to the connecting rail 12, and falls into the slag collecting bucket 8 at the lower end through the slag dropping hole 14 for collection. Similarly, the slag intercepted by the interception box 6 also enters the slag collecting bucket 8 through the slag discharge pipe 7, thereby achieving the effect of cleaning the slag falling into the slide rail 11 and the slag on the frame of the attached placement rack 400 at the same time, achieving a comprehensive cleaning effect.

[0088] Second implementation method:

[0089] Fig.10 Another high-precision mechanical parts cutting device is shown, which is different from the first embodiment in that:

[0090] The left and right sides of the cleaning scraper 3 are provided with guide cone wheels 43, and both sides of the cleaning scraper 3 are provided with cutting edges, so that the cleaning scraper 3 can scrape in both directions, so as to achieve the purpose of performing two-way cleaning on the placement rack 400 within a single stroke (one reciprocating movement along the slide rail 11), and the cleaning effect is better;

[0091] Meanwhile, in this embodiment, a plurality of slag dropping holes 14 (not shown in the figure) may be provided on the slide rail 11 to facilitate periodic cleaning of the slag in the slide rail 11 and prevent the slag from accumulating and affecting the movement of the support slide column 2 .

[0092] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
