[0040] Please refer to Figures 1-11 The application provides the following technical solutions:

[0041] ​​Embodiment 1: In order to solve the problems existing in the actual use of the existing surface grinder, the technical scheme is disclosed as follows, a platform debris self-cleaning numerical control surface grinder, comprising a grinder body 1, and a surface grinder 2 arranged above the grinder body 1, and the top surface of the grinder body 1 is fixedly installed with positioning strip seats 21 on the left and right sides; wherein the left and right sides of the surface grinder 2 are fixedly connected to the upper end of the movable side frame 3, and the lower end of the symmetrically arranged movable side frame 3 is slidably arranged below the grinder body 1; the cleaning mechanism comprises guide screws 14, and the guide screws 14 are rotatably arranged on the left and right sides below the grinder body 1 through bearings, and the rear ends of the symmetrically arranged guide screws 14 are connected to each other through a belt pulley assembly 15, and the lower end of the movable side frame 3 is threadedly connected to the outer wall of the guide screw 14.

[0042] As shown in Figures 1-2 , by installing the positioning platform above the positioning strip seats 21 on the left and right sides above the grinder body 1, the workpiece is fixedly installed with the positioning platform, and then the driving motor installed behind the grinder body 1 works, drives the guide screw 14 connected through the belt pulley assembly 15 to rotate, and then drives the movable side frame 3 connected by threads to move in the front and back directions with the surface grinder 2 on the top, and after moving above the corresponding workpiece, the surface grinder 2 is automatically adjusted in height and orientation, and then the workpiece is subjected to plane grinding, and the debris after grinding falls on the corresponding grinder body 1 above for storage.

[0043] Embodiment 2: In order to solve the problems existing in the actual use of the existing surface grinder, the technical scheme is disclosed as follows, the inside of the grinder body 1 is provided with a cleaning mechanism, and the cleaning mechanism comprises a cleaning slide 4, and the inside of the cleaning slide 4 is fixedly provided with a spray pipe 5, and the left and right sides of the spray pipe 5 are equally spacedly provided with cleaning branch pipes 6; the cleaning slide 4 of the cleaning mechanism is equally spacedly and slidably installed on the top surface of the grinder body 1, and the equally spaced cleaning slide 4 is located inside the left and right positioning strip seats 21, and the top surface height of the positioning strip seat 21 is higher than that of the cleaning slide 4, so that the movement of the cleaning slide 4 is not hindered when the workpiece is positioned by the positioning strip seat 21.

[0044] The front end of the spray pipe 5 of the cleaning mechanism penetrates into the inside below the grinder body 1, and the front end of the spray pipe 5 penetrates and connects to the inside of the pump fan 9, the pump fan 9 delivers air into the spray pipe 5 and the cleaning branch pipe 6, and the outer ends of the equally spaced cleaning branch pipes 6 penetrate into the outside of the cleaning slide 4.

[0045] As shown in Figure 7As shown, when cleaning the debris on the surface of the grinding machine body 1, the pump blower 9 installed at the front of the inside of the grinding machine body 1 operates to deliver airflow to the spray pipe 5 inside the cleaning slide 4. At the same time, the cleaning branch pipe 6 connected to the spray pipe 5 blows the airflow to the outside so that the airflow can carry the debris between the adjacent cleaning slides 4 to collect the debris, so that the debris can be collected and processed from the recovery groove 18 opened inside the grinding machine body 1.

[0046] Example 3: To address the problems existing in the actual use of existing surface grinders, this example discloses the following technical solution: The cleaning mechanism includes a traction bracket 10, the upper end of which is fixedly installed at the rear end of the cleaning slide 4, and the lower end of which is slidably disposed inside the rear of the grinder body 1. The traction bracket 10 and the inner wall of the grinder body 1 are connected to each other by a return spring 11. The cleaning mechanism includes an abutting slide plate 12, which is elastically slidably disposed inside the rear of the grinder body 1. Abutting cones 13 are fixedly installed at equal intervals on the front of the abutting slide plate 12, and the equally spaced abutting cones 13 are correspondingly distributed at the lower end of the traction bracket 10. The abutting slide plate 12 drives the abutting cones 13 to slide, and after squeezing the traction bracket 10, it drives the cleaning slide 4, the spray pipe 5, and the cleaning branch pipe 6 to move, thereby increasing the cleaning range of debris above the grinder body 1.

[0047] A contact wheel 16 is fixedly installed behind the right guide screw 14. The contact wheel 16 interacts with the right end of the contact slide plate 12 through a magnetic component 17. The rotating contact wheel 16 repels the contact slide plate 12 through the magnetic component 17 at an equal angle on the outer wall, and moves back and forth in the left and right directions.

[0048] like Figures 10-11 As shown, after the workpiece surface grinding is completed, the guide screw 14 rotates, driving the threaded movable side frame 3 and the surface grinder 2 to move and reset. The rotating guide screw 14 drives the rear-end abutting wheel 16 and magnetic component 17 to rotate. The abutting slide plate 12, which repels the magnetic component 17, drives the abutting cone block 13 on the outer wall to move back and forth in the left and right directions. After the abutting cone block 13 presses against the lower end of the traction bracket 10, it drives the traction bracket 10 and the cleaning slide 4 fixedly connected to its top to move back and forth in the front and back directions. This causes the cleaning slide 4 to drive the internal spray pipe 5 and cleaning branch pipe 6 to move back and forth, so as to increase the cleaning range of the debris on the top surface of the grinding machine body 1 and avoid the existence of cleaning dead corners.

[0049] Example 4: In order to solve the problems existing in the actual use of the existing surface grinder, this example discloses the following technical solution: The grinding machine body 1 is provided with a recovery mechanism, and the recovery mechanism includes a recovery cross plate 7, and a recovery arc frame 8 is fixedly installed at equal intervals above the recovery cross plate 7; the recovery mechanism includes recovery grooves 18 that are opened at equal intervals inside the grinding machine body 1, and the recovery grooves 18 and the cleaning slide 4 are distributed in an alternating manner, and the interior of the recovery grooves 18 is slidably connected to the lower end of the recovery arc frame 8, and the recovery arc frame 8 slides through the upper part of the recovery grooves 18, while the outer end of the recovery arc frame 8 is attached to and slides against the outer wall of the cleaning slide 4.

[0050] The recycling mechanism includes a collection bracket 19, which is fixedly installed at equal intervals on the front and rear sides of the top face of the grinding machine body 1. The collection brackets 19 are symmetrically distributed on the front and rear sides of the top face of the recycling groove 18. The outer ends of the collection brackets 19 are rotatably connected to the inner end of the collection plate 20 by torsion springs. At the same time, the inner end of the collection plate 20 is attached to the outer wall of the cleaning slide 4.

[0051] The recycling mechanism includes a collection bracket 19 and a collection rotating plate 20 to prevent debris from splashing to the outside of the grinding machine body 1. The collection bracket 19 and the collection rotating plate 20, which are symmetrically distributed front and back, are arranged in opposite directions. The collection rotating plate 20 contacts the inner wall of the moving recycling arc frame 8 so as to flip inward to gather the debris carried by the recycling arc frame 8 and push it into the recycling groove 18 for cleaning.

[0052] The outer end of the recycling horizontal plate 7 included in the recycling mechanism is fixedly connected to the inner wall of the movable side frame 3, and the movable side frame 3 drives the surface grinder 2 and the recycling horizontal plate 7 to move back and forth in the direction of processing, so that after processing is completed, the debris is cleaned up by the recycling mechanism and the cleaning mechanism.

[0053] like Figures 8-9 As shown, during the movement of the movable side frames 3 on the left and right sides of the grinding machine body 1, the recovery cross plate 7 installed inside the grinding machine body 1 moves in the front and back direction. At the same time, the recovery arc frame 8, which is fixedly installed above the recovery cross plate 7, is driven to slide above the grinding machine body 1. Simultaneously, the recovery arc frame 8 drives the uncleaned debris above the adjacent cleaning slide bar 4 to collect the debris. The inclined surface at the outer end of the recovery arc frame 8 drives the debris to slide inward so that it can be collected through the recovery groove 18.

[0054] Further, the scraps driven by the recycling arc frame 8 are moved in the front-back direction, and when the recycling arc frame 8 and the converging rotating plate 20 at the outer end of the converging support 19 are mutually attached, the converging rotating plate 20 is slid inwards by being pressed by the inclined surface, so that the outer end of the converging rotating plate 20 is rotated inwards after being pressed, and the scraps pushed by the recycling arc frame 8 are synchronously collected inwards, and then the residual scraps are collected through the recycling strip groove 18, so as to avoid the influence of the residual scraps on the subsequent working operation.

[0055] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
