Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a grinding machine tool. Background Technology

[0002] The utility model patent, entitled "A Grinding Machine Tool" with patent number CN117359497A, features a worktable mounted on the upper end of a base. A machine body is mounted on the upper end of the worktable. Fixed plates are located on the rear and sides of the upper end of the worktable, surrounding the sides and back of the machine body. A fixed rail is located on the front of the upper end of the worktable. Movable plates are located on both sides between the fixed rails, sliding between them. A slide rail is located on the top of the back of each movable plate, and a cleaning mechanism is slidably connected to the slide rail. This device, with its fixed and movable plates, prevents material from splashing into the surrounding environment during grinding, providing additional safety protection. The movable plates can slide to the sides, allowing the user to operate the internal machinery. Closing the movable plates during grinding prevents material splashing, thus achieving the desired effect.

[0003] However, in actual operation, the machine tool needs to be cleaned after each day's work. The movable plate in the above patent only has the functions of opening, closing and protection, which makes cleaning more troublesome. Therefore, it is necessary to improve it. Utility Model Content

Detailed Implementation

[0030] like Figure 1-2 As shown, a grinding machine tool includes a base 1, which includes a seat 11. A magnetic chuck 14 is provided at the upper end of the seat 11. A first motor 12 is fixedly connected to the top interior of the seat 11 via a bracket. The output shaft of the first motor 12 passes through the seat 11 and is fixedly connected to the magnetic chuck 14. An arc-shaped protective plate 2 is fixedly connected to the upper end of the seat 11. Two movable devices 4 are provided at both ends of the protective plate 2, which slide and engage with it. The two movable devices 4 and the protective plate 2 form an annular retaining ring. The movable devices 4 and the protective plate 2 can intercept waste chips during processing, preventing them from splashing onto the operator. Simultaneously, the relative movement between the movable devices 4 and the protective plate 2 can scrape off waste chips from the inner wall of the protective plate 2, saving cleaning time.

[0031] like Figure 4 , Figure 6 As shown, each movable device 4 includes an arc-shaped inner plate 41 and an outer plate 42. One end of the inner plate 41 and the outer plate 42 are fixedly connected. A sliding groove 43 is provided between the inner plate 41 and the outer plate 42 to slide with the protective plate 2. A collection groove 44 is fixedly connected to the upper outer side of the outer plate 42.

[0032] After the active device 4 is opened (e.g.) Figure 6 (As shown in the diagram), the protective plate 2 is completely located within the slide groove 43 to prevent debris from falling into the slide groove 43 when the brush is cleaning debris.

[0033] like Figures 2-3 As shown, a grinding device 3 is also fixedly connected to the upper end of the base 11. The grinding device 3 includes a fixed rod 31, which is vertically fixedly connected to the upper end of the base 11. A first telescopic rod 32 is horizontally fixedly connected to the inner side of the fixed rod 31. The first telescopic rod 32 includes a fixed sleeve fixed to the fixed rod 31, and a movable sleeve is slidably provided at one end of the fixed sleeve. A first hydraulic cylinder 33 is provided inside the first telescopic rod 32. The cylinder body of the first hydraulic cylinder 33 is fixed to the inner bottom surface of the fixed sleeve, and the piston rod of the first hydraulic cylinder 33 is fixed to the inner top surface of the movable sleeve. A second telescopic rod 34 is fixedly connected to the lower end of the movable sleeve of the first telescopic rod 32. The structure of the second telescopic rod 34 is similar to that of the first telescopic rod 32, also including a fixed sleeve vertically fixed to the lower part of the end of the first telescopic rod 32, and a movable sleeve is slidably provided at one end of the fixed sleeve. A second hydraulic cylinder 35 is provided inside the second telescopic rod 34. The cylinder body of the second hydraulic cylinder 35 is fixed to the inner bottom surface of the fixed sleeve, and the piston rod of the second hydraulic cylinder 35 is fixed to the inner top surface of the movable sleeve. The lower end of the movable sleeve of the second telescopic rod 34 is fixedly connected to the second motor 36, and the output shaft of the second motor 36 is fixedly connected to the grinding disc 37.

[0034] like Figure 2 , Figure 5-6 As shown, a third motor 13 is also fixedly connected inside the base 11. There are two sets of third motors 13, and a screw 6 is fixedly connected to the output shaft of each third motor 13. Both screws 6 are threadedly connected to the movable ring 5. When the two third motors 13 start synchronously, the movable ring 5 achieves vertical lifting and lowering.

[0035] like Figure 5 As shown, the movable ring 5 includes a circular ring 51 with two threaded holes 54 that are threaded to the corresponding screws 6. A conical surface 52 is provided on the outer side of the circular ring 51. The outer edge of the conical surface 52 contacts the inner wall of the inner plate 41 to achieve scraping. The conical surface 52 is lower on the outer edge and higher on the inner edge. Multiple partition plates 53 are fixedly connected to the conical surface 52. By setting the conical surface 52, when the movable ring 5 moves vertically up and down, the outer edge of the conical surface 52 scrapes against the inner wall of the inner plate 41 to clean the debris on the inner wall of the inner plate 41. The conical surface 52 and partition plates 53 can also hold debris, facilitating subsequent cleaning.

[0036] like Figures 4-5 As shown, the free end of the inner plate 41 is provided with an inclined surface 45, and a triangular plate 55 is fixedly connected to the outer circular surface of the ring 51. When the movable device 4 is opened, it is as follows: Figure 8As shown in the diagram, the inclined surface 45 contacts the inclined surface of the triangular plate 55, causing the ring 51 to move upwards. The triangular plate 55 can then scrape the inclined surface 45, ensuring a more thorough cleaning.

[0037] The magnetic chuck 14 is equipped with multiple auxiliary clamps 15 that engage with it. When machining a magnetically conductive workpiece 16, it is directly magnetically attracted to the magnetic chuck 14. When machining a non-magnetically conductive workpiece 16, it is attracted to the magnetic chuck 14 through the auxiliary clamps 15, with the inner side of the auxiliary clamps 15 pressing against the workpiece 16, thus clamping the workpiece 16. The auxiliary clamps 15 can be magnetically conductive blocks with strong magnetic force, ensuring that the magnetic attraction force during operation is sufficient to prevent the workpiece 16 from shifting during grinding.

[0038] The working principle is:

[0039] 1) When using this device, place the workpiece 16 on the upper end of the magnetic chuck 14, and then push the two movable devices 4 to move them towards each other until... Figure 1 The state shown.

[0040] 2) Then, the length of the first telescopic rod 32 is adjusted by the first hydraulic cylinder 33, and the length of the second telescopic rod 34 is adjusted by the second hydraulic cylinder 35, so that the grinding disc 37 is moved to the processing position, and the second motor 36 is started to grind the workpiece 16.

[0041] During processing, waste chips will fly in all directions and land on the inner walls of the inner plate 41 and the protective plate 2.

[0042] 3) After processing is complete, open the movable device 4 until... Figure 6 As shown in the diagram, during the movement of the movable device 4, the inclined surface 45 on the inner plate 41 scrapes against the inner wall of the protective plate 2, pushing the debris splashed on the inner wall of the protective plate 2 towards the middle position of the protective plate 2 or causing it to fall onto the conical surface 52 of the ring 51 located inside the inner plate 41. Subsequently, the third motor 13 is started, which drives the screw 6 to rotate, thereby driving the ring 51 to move upward, so that the conical surface 52 of the ring 51 scrapes against the inner circular surface of the inner plate 41 until it moves to the top. Then, the debris at the top of the ring 51 can be swept away with a brush or other tools, making it more convenient and efficient to clean the debris on the inner side of the protective plate 2 and the inner plate 41.
