Description

Technical Field

[0001] This utility model belongs to the field of machine tool cutting technology and relates to a reciprocating scraper chip conveyor. Background Technology

[0002] A scraper chip conveyor is a chip removal device used during machine tool cutting to remove metal or non-metal chips. It is widely used in CNC machine tools, machining centers, milling machines and other equipment. It mainly consists of a drive unit, a conveyor chain, a scraper and other mechanisms, which can improve the automation level and production efficiency of machine tools.

[0003] When using the above technology, the following technical problems were found in the prior art: when scraping the debris that falls into the device, the bottom of the scraper is always in contact with the worktable. The continuous friction between the scraper and the worktable may aggravate its wear and reduce the service life of the device. Utility Model Content

[0004] The technical problem this invention aims to solve is that when scraping debris that falls into the device repeatedly, the bottom of the scraper is always in contact with the worktable. The continuous friction between the scraper and the worktable may accelerate wear and reduce the service life of the device.

[0005] The present invention relates to a reciprocating scraper chip conveyor, comprising a worktable; a support leg fixedly connected to the bottom outer side of the worktable; a sliding groove A fixedly connected to the bottom outer side of the worktable; a rotating lead screw installed inside the sliding groove A; a slider threadedly connected to the outside of the rotating lead screw; and the slider sliding inside the sliding groove A.

[0006] The reciprocating scraping assembly is located on the outside of the worktable; the reciprocating scraping assembly includes a guiding mechanism, a one-way limiting mechanism and a sliding limiting mechanism, which are used in cooperation with each other.

[0007] The reciprocating scraping assembly includes a connecting plate; the connecting plate is connected to the slider; multiple sets of telescopic rods A are fixedly connected to the outside of the connecting plate; a moving roller is fixedly connected to the telescopic section of the telescopic rod A; a guide groove is fixedly connected to the top of the outside of the worktable; the moving roller is slidably connected inside the guide groove; a connecting block is connected to the bottom of the moving roller; a scraper is installed at the bottom of the connecting block.

[0008] The sliding limiting mechanism includes a sliding groove B; the sliding groove B is located at the top of the inner side of the guide groove; a telescopic rod B is fixedly connected to the top of the moving roller; the telescopic end of the telescopic rod B slides inside the sliding groove B.

[0009] The one-way limiting mechanism includes a placement groove; the placement groove is located on the top outer side of the worktable; a rotating shaft is hinged inside the placement groove; a return spring is installed inside the rotating shaft; one outer end of the return spring is fixedly connected to the inner side wall of the placement groove; a limiting block is fixedly connected to the outer side of the return spring; a guide slope is provided on one side of the outer side of the limiting block.

[0010] An inclined plate is provided on the outer side of the scraper.

[0011] The outer side of the inclined plate is inlaid with ceramic pieces.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the combined use of the guiding mechanism and the one-way limiting mechanism, when the scraper is continuously scraping and cleaning the debris on the top of the worktable, it will leave the top of the worktable when returning inside the guide groove. This reduces the impact of the scraper on the debris that subsequently falls onto the top of the worktable when it returns. At the same time, it can stay in close contact with the worktable surface when it moves forward, so that the scraper will not always be in contact with the worktable surface, thus preventing continuous friction between the scraper and the worktable. This reduces the wear between the worktable and the scraper and improves the service life of the device.

[0013] By providing an inclined plate at the bottom front side of the scraper, the curvature of the inclined plate grips and rolls up the debris when the scraper is cleaning it, while also having a strong anti-scratching ability. This makes the contact area between the scraper and the worktable surface narrower, further reducing the friction between the two and improving the service life of the device.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0025] like Figures 1-5 As shown, a reciprocating scraper chip conveyor includes a worktable 1; a support leg 2 is fixedly connected to the bottom outer side of the worktable 1; a sliding groove A3 is fixedly connected to the bottom outer side of the worktable 1; a rotating lead screw 4 is installed inside the sliding groove A3; a slider 5 is threadedly connected to the outside of the rotating lead screw 4; the slider 5 slides inside the sliding groove A3.

[0026] A reciprocating scraping assembly is located on the outside of the worktable 1. The reciprocating scraping assembly includes a guiding mechanism, a one-way limiting mechanism, and a sliding limiting mechanism. The one-way limiting mechanism and the sliding limiting mechanism work together. The reciprocating scraping assembly includes a connecting plate 6. The connecting plate 6 is connected to a slider 5. Multiple sets of telescopic rods A7 are fixedly connected to the outside of the connecting plate 6. A moving roller 8 is fixedly connected to the telescopic section of the telescopic rod A7. A guide groove 9 is fixedly connected to the top of the outside of the worktable 1. The moving roller 8 is slidably connected inside the guide groove 9. A connecting block 10 is connected to the bottom of the moving roller 8. A scraper rod 11 is installed at the bottom of the connecting block 10. The sliding limiting mechanism includes a sliding groove B12. The sliding groove B12 is located at the top of the inner side of the guide groove 9. A telescopic rod B12 is fixedly connected to the top of the moving roller 8. 13; The telescopic end of the telescopic rod B13 slides inside the sliding groove B12. The one-way limiting mechanism includes a placement groove 14; the placement groove 14 is located on the top outer side of the workbench 1; a rotating shaft 15 is hinged inside the placement groove 14; a return spring 16 is installed inside the rotating shaft 15; one outer end of the return spring 16 is fixedly connected to the inner wall of the placement groove 14; a limiting block 17 is fixedly connected to the outer side of the return spring 16; a guide slope 18 is provided on one side of the outer side of the limiting block 17. The direct cooperation between the return spring 16 and the rotating shaft 15 allows the limiting block 17 to move only in one direction when the inner wall of the placement groove 14 is raised. However, when the limiting block 17 is pushed from another angle, the limiting block 17 can move completely, and it can also automatically reset under the use of the return spring 16.

[0027] During operation, when the chips generated by the machine tool fall onto the top of the worktable 1, the drive screw 4 begins to rotate continuously at the front of the sliding groove A3. The slider 5, which is threaded to the outside of the drive screw 4, slides inside the sliding groove A3. The sliding of the slider 5 causes the connecting plate 6 to slide at the bottom inside the worktable 1. Then, the connecting plate 6 drives the telescopic rod A7 to reciprocate continuously. Multiple sets of telescopic rods A7 pull the moving roller 8 to move inside the guide groove 9. The use of the telescopic rods A7 causes the moving roller 8 to slide continuously inside the guide groove 9. In this configuration, when the moving roller 8 is pressed by the guide slope 18, it can be supported from the bottom to move upward. When the moving roller 8 leaves the limiting block 17, it can be reset to normal operation. However, if the guide slope 18 and the limiting block 17 do not cooperate to press it upward, the moving roller 8 simply slides on the top of the worktable 1, and the telescopic rod A7 will not extend or retract. In this case, the connecting block 10 moves continuously on the top of the worktable 1, causing the scraper 11 to move forward, thus protecting the scraper on the top of the worktable 1. When cleaning and scraping debris, as the moving roller 8 slides inside the guide groove 9, the telescopic rod B13 also slides synchronously inside the sliding groove B12. Through the cooperation of the sliding groove B12 and the telescopic rod B13, the moving roller 8 is confined inside the guide groove 9. During the sliding of the moving roller 8 inside the guide groove 9, some debris may be squeezed into the bottom of the scraper rod 11 while it is scraping the device. This foreign object intrusion may cause the scraper rod 11 to bend, leading to machine malfunctions. The overload situation can lead to machine damage and reduced service life of the scraper 11. Therefore, through the cooperation of the sliding groove B12 and the telescopic rod B13, when the scraper 11 is scraping debris, if the debris invades the bottom of the scraper 11 and encounters huge resistance, the telescopic rod B13 will begin to retract, and the scraper 11 will begin to move to the side. This reduces the intrusion of foreign objects into the bottom of the scraper 11, which could cause the scraper 11 to deform or the machine to overload. This increases the service life of the device and provides self-protection against foreign object intrusion.

[0028] When the scraper 11 moves in the opposite direction, the moving roller 8 will contact the limiting block 17 on the inner side of the placement groove 14 and the worktable 1. The moving roller 8 will squeeze the limiting block 17. Due to its shape, the limiting block 17 is limited by the inner wall of the placement groove 14 and cannot move. At this time, the guide slope 18 will convert the lateral force of the moving roller 8 into a longitudinal force. The moving roller 8 will then be pulled upward, and the moving roller 8 will pull the telescopic rod A7 to move upward, causing the scraper 11 to leave the surface of the worktable 1. Then it will continue to move. When the moving roller 8 disengages from the limiting block 17, the telescopic rod A7 will... The reset process begins, causing the scraper 11 to re-engage with the surface of the worktable 1. As the scraper 11 moves forward again, it is squeezed from the side of the limiting block 17 away from the guide slope 18. At this time, the limiting block 17 lacks a limit and begins to rotate around the rotating shaft 15 under the pressure of the moving roller 8, causing the limiting block 17 to sink entirely into the placement groove 14. While the limiting block 17 is rotating, the reset spring 16 begins to deform under the force of rotation. When the moving roller 8 leaves the top of the placement groove 14, the reset spring 16 begins to rebound, resetting the limiting block 17 for continued use next time.

[0029] By using the guide mechanism and the one-way limiting mechanism in combination, the scraper 11, while continuously scraping and cleaning the debris on the top of the worktable 1, will leave the top of the worktable 1 when returning inside the guide groove 9. This reduces the impact of the scraper 11 on the debris that subsequently falls onto the top of the worktable 1 when it returns. At the same time, it can remain in close contact with the surface of the worktable 1 when it moves forward, so that the scraper 11 will not always be in contact with the surface of the worktable 1, thus preventing continuous friction between the scraper 11 and the worktable 1. This reduces the wear between the worktable 1 and the scraper 11 and improves the service life of the device. Example

[0030] like Figures 1-3 As shown, an inclined plate 19 is provided on the outer side of the scraper 11, and a ceramic plate is inlaid on the outer side of the inclined plate 19. The ceramic plate has the characteristics of high hardness and strong wear resistance. When the scraper 11 cleans the debris by passing through the inclined plate 19, the inclined plate 19 directly contacts the debris, which provides a certain degree of protection for the scraper 11 itself. When the ceramic plate is worn, it can be disassembled and replaced, which further improves the practicality and flexibility of the device.

[0031] During operation, a sloping plate 19 is provided at the bottom front side of the scraper 11. When the scraper 11 cleans up the debris, the curvature of the sloping plate 19 will grab the rolled debris and have a strong anti-scratching ability. This makes the contact area between the scraper 11 and the surface of the worktable 1 narrower, further reducing the friction between the two and improving the service life of the device.
