Description

Technical Field

[0001] The present invention relates to the technical field of chip removal of machine tools, and more particularly to a chip removal machine with a scraper. Background Art

[0002] In the current field of machine tool manufacturing and use, the efficiency and reliability of the chip removal system has always been a technical problem that has received much attention. The waste generated by traditional machine tools during the processing, especially the long metal chips, often have serious accumulation and entanglement due to their special shape and material characteristics. These long metal chips are easy to stick to each other during the discharge process to form large clumps. This phenomenon not only increases the burden on the chip removal system, but also may cause chip accumulation in the working area of ​​the machine tool, affecting the processing accuracy and work efficiency. What is more serious is that these entangled metal chips may interfere with the normal operation of the machine tool and even cause equipment damage or safety hazards.

[0003] The plate chain conveyor mechanism that is widely used at present faces significant limitations when handling such large-volume metal chip clumps. The traditional plate chain conveyor system mainly relies on the friction between the lower surface of the conveyor belt and the waste to achieve the conveying function. However, when encountering large-volume metal chip clumps, due to the limited contact area, the plate chain cannot generate enough thrust to effectively move these wastes, which results in a large amount of metal chips cannot be removed in time, which not only reduces the chip removal efficiency, but also may cause blockage or damage to the conveying system. The long-term accumulation of waste will not only affect the normal operation of the machine tool, but also increase maintenance costs and downtime. Summary of the invention

This design realizes the precise guiding and limiting functions of the adjustment block through the cooperation of the contraction groove and the lateral bar. The sliding design of the lateral bar in the contraction groove not only ensures the smooth movement of the adjustment block, but also effectively prevents the deflection of the adjustment block, thereby ensuring the stability of use.

This design forms overload protection through the combination of the pressure rod and the pressure ball, and the cooperation between the pressure ball and the overload groove provides reliable force transmission and overload protection function. When an overload occurs, the pressure ball can be separated from the overload groove in time, effectively protecting the equipment from damage.

[0008] Preferably, each of the pressure rods is respectively installed with a compression spring, and a push block is installed on the compression spring, and a screw is installed in the vertical groove thread, and the screw is pressed on the push block.

Two-way sleeves are threadedly connected on both sides of the follower sleeve, and the two-way sleeves are in contact with the push plates. This design achieves uniform force transmission through the cooperation of the push rod and the push plate, and the threaded connection design of the two-way sleeve provides a preload adjustment function to ensure the stability of the installation.

[0010] Preferably, a receiving sleeve is installed in the follower sleeve, and limiting tubes are respectively installed on the two inner sleeves, the limiting tubes are slidably connected in the receiving sleeve, an intermediate disk is installed in the receiving sleeve, and multiple return springs are respectively installed on the two limiting tubes, and the multiple return springs respectively abut against the two sides of the intermediate disk. This design achieves the limiting stability of the inner sleeve through the cooperation of the limiting tube and the receiving sleeve.

[0014] Compared with the prior art, the present invention provides a chip conveyor with a scraper, which has the following beneficial effects: The equipment forms an efficient scraping system through the uniform distribution of multiple rotating disks, combined with the combination of arc springs and dispersion springs. This design can not only effectively handle ordinary metal chips, but more importantly, it can effectively handle metal chips that are entangled in a mass, significantly improving the chip removal efficiency. Secondly, through the cooperation of the arc plate and the fitting barrel, combined with the chain conveying system, dual processing of metal chips is achieved. When encountering large-volume mass metal chips, the system can compress them and increase the contact area with the chain through the impact of the arc spring and the dispersion spring, and increase the force in the conveying direction, thereby improving the conveying efficiency. Through the precisely designed combination of the drive sleeve and the internal sleeve, combined with the setting of the adjustment block and the pressure ball, reliable overload protection is formed. When encountering an overload situation, the pressure ball can automatically detach from the overload slot, effectively preventing equipment damage and ensuring the safe operation of the equipment.

[0015] Through the cooperation of the limiting tube and the receiving sleeve, combined with the design of the push plate and the ejector rod, the rapid installation and disassembly of the components can be achieved.

DETAILED DESCRIPTION

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0021] See also Figures 1 to 9 A chip conveyor with a scraper comprises a plurality of rotating disks 11 installed at equal intervals; further comprising a driving mechanism, the driving mechanism comprising an arc spring 21 installed on the plurality of rotating disks 11, each arc spring 21 being respectively installed with a plurality of dispersion springs 22, each rotating disk 11 being respectively installed with a fitting barrel 23, the plurality of fitting barrels 23 being fitted on an arc plate 24, and each fitting barrel 23 being respectively installed with an intermediate ring 25, the arc plate 24 being provided with intermediate grooves 26 of the same number as the rotating disk 11, the intermediate ring 25 being rotatably connected in the intermediate groove 26, and the plurality of arc springs 21 being able to pass through the intermediate groove 26, the driving mechanism further comprising a fixed installation A conveying frame 27 on the external equipment, an arc plate 24 is installed on the conveying frame 27, a pressure plate 28 is installed on the arc plate 24, and the pressure plate 28 is connected to the conveying frame 27, a lateral motor 29 is fixedly installed on the conveying frame 27, the protruding end of the lateral motor 29 is connected to the synchronization rod 210, a plurality of internal sleeves 32 are respectively provided with hexagonal grooves 211, the synchronization rod 210 is slidably connected in the plurality of hexagonal grooves 211, a driving motor 212 is fixedly installed on the conveying frame 27, a driving shaft 213 is installed on the protruding end of the driving motor 212, a chain plate 214 is rotatably installed on the conveying frame 27, and the chain plate 214 is connected to the driving shaft 213.

[0022] See also Figure 1When the metal chips are transported, the driving motor 212 is first started, which will drive the driving shaft 213 to rotate. Since the chain plate 214 is connected to the driving shaft 213, it will rotate accordingly, and the metal chips will enter the side close to the arc spring 21, and then the generated metal chips will be discharged with the conveyance of the chain plate 214. When large clusters of metal chips appear, they cannot be discharged only by the conveyance of the chain plate 214. Under the action of the lateral motor 29, the synchronous rod 210 drives the multiple rotating disks 11 to rotate. Since the rotating disk 11 is equipped with a fitting barrel 23, and the fitting barrel 23 is fitted on the arc plate 24, the rotating disk 11 rotates along the arc plate 24, and the middle ring 25 rotates in the middle groove 26 to fill the gap in the middle groove 26, and then the multiple arc springs 21 pass through the middle groove 26, and then the arc spring 21 drives the multiple dispersion springs 22 to rotate. At this time, the arc spring 21 and the dispersion spring 22 have corresponding speeds, and then the arc spring 21 and the dispersion spring 22 impact on the ball-shaped metal chips to compress the metal chips, and then press them into the lower end of the arc plate 24. Since the metal chips are compressed, they have greater friction with the chain plate 214, and at this time, the metal chips are driven to be transported along the chain plate 214, so that they are discharged, and then the chip removal process is completed.

[0023] See also Figures 3 to 9The overload mechanism includes a driving sleeve 31 installed on each rotating disk 11, two inner sleeves 32 are symmetrically installed in each driving sleeve 31, and a plurality of adjustment blocks 33 are respectively fitted and installed on the side walls of each inner sleeve 32. A follower sleeve 34 is installed on the driving sleeve 31, and a plurality of transverse grooves 35 are respectively opened at equal intervals on both sides of the follower sleeve 34 along the axis, and the adjustment blocks 33 are slidably connected in the transverse grooves 35. The overload mechanism also includes a contraction groove 36 opened in each transverse groove 35, and lateral bars 37 are respectively installed on both sides of each adjustment block 33, and the lateral bars 37 are slidably connected in the contraction groove 36. Two vertical grooves 38 are respectively opened on each adjustment block 33, and a pressure rod 39 is respectively slidably connected in each vertical groove 38, and a pressure ball 310 is installed on the pressure rod 39. Overload grooves 311 with the same number as the adjustment block 33 are respectively opened on both sides of each inner sleeve 32, and the pressure ball 310 is pushed into the overload groove 311, each pressure rod 39 is respectively installed with a compression spring 312, and a push block 313 is installed on the compression spring 312, a screw rod 314 is installed on the internal thread of the vertical groove 38, and the screw rod 314 presses on the push block 313, and each adjustment block 33 is respectively installed with a push rod 315, and a push plate 316 is respectively installed on the two internal sleeves 32, and multiple push rods 315 are respectively against the push plate 316, and the two sides of the follower sleeve 34 are respectively A two-way sleeve 317 is threadedly connected, and the two-way sleeve 317 abuts against the push plate 316, a receiving sleeve 318 is installed in the follower sleeve 34, and limiting tubes 319 are respectively installed on the two inner sleeves 32. The limiting tubes 319 are slidably connected in the receiving sleeve 318, and an intermediate disk 320 is installed in the receiving sleeve 318. Multiple return springs 321 are respectively installed on the two limiting tubes 319, and the multiple return springs 321 respectively abut against the two sides of the intermediate disk 320.

[0024] Since the dispersion spring 22 and the plurality of arc springs 21 will be entangled on the metal chips during rotation, if the synchronization rod 210 and the rotating disk 11 are rigidly connected, the rotating disk 11 will be stuck, thereby causing damage to the motor. Therefore, the rigid connection is avoided by connecting the pressure ball 310 and the overload slot 311.

[0025] See also Figure 4 and Figure 5 Since the synchronization rod 210 is stuck in the hexagonal groove 211, it is rigidly connected to the multiple internal sleeves 32, and then the adjustment block 33 is slidably connected to the pressure rod 39. The pressure ball 310 on the pressure rod 39 is pressed in the overload groove 311, so a corresponding clamping force is applied. Please refer to Figure 7 When the rotating disk 11 is stuck and the driving force exceeds the elastic force of multiple compression springs 312, the pressure ball 310 will slide upward along the overload groove 311 to compress the compression spring 312, and then release the connection between the pressure ball 310 and the inner sleeve 32, avoiding damage caused by excessive force and ensuring safety in use.

[0026] When installation and disassembly are required, first insert the limiting tube 319 into the receiving sleeve 318, and then make the push plate 316 contact with multiple push rods 315. As the sliding continues, the lateral strips 37 on the adjusting block 33 slide along the shrinkage groove 36, and then the pressurizing ball 310 in the adjusting block 33 will move toward the axis and finally make the pressurizing ball 310 stuck in the overload groove 311. Then, the two-way sleeve 317 is threadedly connected to the follower sleeve 34 and the two-way sleeve 317 is pressed against the push plate 316. The pre-tightening force is applied by the two-way sleeve 317, and then the stability of the installation is guaranteed. The limiting tube 319 is slidably connected in the receiving sleeve 318, thereby ensuring the limitation of the inner sleeve 32 and further ensuring the stability of use.

[0027] Since each rotating disk 11 is separately arranged, a jam in one position will not affect other rotating disks 11 , but the machine needs to be shut down for maintenance until all the rotating disks 11 are normal and then the corresponding driving process can be performed.

[0028] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
