Description

Technical Field

[0001] This invention relates to the field of grinding technology, specifically to a CNC vertical multi-functional grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses abrasive wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives, such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Grinding machines with a vertical worktable are simply called vertical grinding machines.

[0003] Existing CNC vertical grinding machines are mostly single-function, only capable of grinding simple ring-shaped workpieces, and are very inconvenient to operate, affecting the grinding efficiency. Therefore, we propose a CNC vertical multi-functional grinding machine. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a CNC vertical multi-functional grinding machine to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a CNC vertical multi-functional grinding machine, comprising a base, a support frame fixedly connected to the top of the base, a grinding device fixedly connected to the outer surface of the support frame, and a support device provided at the central axis of the top of the base;

[0008] The support device includes a support plate, a vertical rod is fixedly connected to the bottom of the support plate, the bottom of the vertical rod is rotatably connected to the top of the base through a rotating shaft, a pressing mechanism is fixedly connected to the top of the support plate, and a limit mechanism and a lifting mechanism are provided at the bottom of the support plate.

[0009] Preferably, the bottom of the support plate has four sliding grooves in a ring, and the bottom of the support plate has an annular groove. All four sliding grooves are connected to the annular groove. The top of the support plate has two slots, and the surfaces of the two slots are provided with connecting grooves. The two connecting grooves are respectively connected to two of the sliding grooves.

[0010] Preferably, the clamping mechanism includes a fixed rod, a connecting sleeve is fitted on the outer surface of the fixed rod, two pressure plates are fixedly connected to the outer surface of the connecting sleeve, and a fixing bolt is threadedly connected to the outer surface of the connecting sleeve.

[0011] Preferably, the limiting mechanism includes a slider, a retaining bead is embedded at the top of the slider, a second slot is provided at the bottom of the slider, the upper end of the slider and the retaining bead are both disposed inside the slot, and the width of the slider is the same as the width of the slot.

[0012] Preferably, the limiting mechanism further includes a base plate, the bottom of which is fixedly connected to the top of the base, and a fixing block is fixedly connected to the central axis of the top of the base plate. The slider slides in contact with the fixing block through a second slot opened at the bottom. A first placement slot is opened on the surface of the base plate, and a second placement slot is opened at the left end of the first placement slot. The widths of the first placement slot and the second placement slot are the same.

[0013] Preferably, a connecting frame is provided inside the placement slot, the bottom of the connecting frame contacts the top of the base plate, the outer surface of the connecting frame contacts the wall of the placement slot, and two connecting plates are fixedly connected to the surface of the connecting frame, both of which are in contact with the surface of the slider.

[0014] Preferably, the lifting mechanism includes a fixed frame, which is fixedly connected to the surface of the slider. A limit frame is fixedly connected to the upper end of the fixed frame. A connecting rod 2 is provided at the upper end of the fixed frame, and a slot 3 is provided at the lower end of the connecting rod 2. The limit frame passes through the slot 3.

[0015] Preferably, a deflection plate is fixedly connected to the top of the second connecting rod, a first connecting rod is provided at the left end of the inside of the deflection plate, the second connecting rod is provided inside the communicating groove, the deflection plate is provided inside the first slot, and the deflection plate is rotatably connected to the first slot through the second connecting rod.

[0016] Compared with the prior art, the present invention provides a CNC vertical multi-functional grinding machine, which has the following beneficial effects:

[0017] 1. This invention places the annular workpiece in the middle of the support plate, then fits the annular workpiece onto the outer surface of the fixing rod. After the connecting sleeve is fitted onto the outer surface of the fixing rod, the connecting sleeve causes the pressure plate to move vertically downward along the fixing rod until the pressure plate contacts the top of the annular workpiece. The connecting sleeve can then be fixed by rotating the fixing bolt, thereby ensuring the fixing effect of the annular workpiece and preventing the annular workpiece from shaking during grinding, which would affect the grinding effect.

[0018] 2. The present invention sets a slider and a retaining ball in a groove opened at the bottom of the support plate. The slider is connected to the fixing block through a second slot opened at the bottom. The stability of the slider is ensured by setting a connecting frame and a connecting plate at the upper end of the base plate. This ensures that the support plate can be prevented from deflecting when it is being polished by the polishing device.

[0019] 3. When further grinding of the annular workpiece after grinding by the grinding device is required, the present invention moves the connecting frame upward and slides it into the placement groove two. This allows the slider to slide into the annular groove through the retaining ball, thereby releasing the slider's restriction on the support plate. The support plate can then be rotated by the vertical rod, facilitating further manual fine grinding of the annular workpiece.

[0020] 4. By installing a fixing frame on the surface of the slider, after the annular workpiece is ground and the connecting sleeve is removed, the slider can be moved to make the fixing frame slide along the fixing block. When the fixing frame slides, it can squeeze the connecting rod two, so that the connecting frame is squeezed upward under the restriction of the limiting frame. In this way, the connecting rod two can drive the deflection plate along the connecting groove and the slot one to deflect the connecting rod one to help lift the annular workpiece, avoiding the situation where the annular workpiece is stuck on the surface of the support plate and is difficult to remove.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Please see Figure 1-7 The present invention provides a technical solution: a CNC vertical multi-functional grinding machine, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a grinding device 3 fixedly connected to the outer surface of the support frame 2, and a support device 4 provided at the central axis of the top of the base 1.

[0033] The support device 4 includes a support plate 41, a vertical rod 43 is fixedly connected to the bottom of the support plate 41, the bottom of the vertical rod 43 is rotatably connected to the top of the base 1 through a rotating shaft, a pressing mechanism 42 is fixedly connected to the top of the support plate 41, and a limit mechanism 44 and a lifting mechanism 45 are provided at the bottom of the support plate 41.

[0034] The bottom of the support plate 41 has four sliding grooves 411 and an annular groove 412. All four sliding grooves 411 are connected to the annular groove 412. The top of the support plate 41 has two slots 413. The surfaces of the two slots 413 are provided with connecting grooves 414. The two connecting grooves 414 are connected to the two sliding grooves 411 respectively.

[0035] The clamping mechanism 42 includes a fixed rod 421, a connecting sleeve 422 on the outer surface of the fixed rod 421, two pressure plates 423 fixedly connected to the outer surface of the connecting sleeve 422, and a fixing bolt 424 threadedly connected to the outer surface of the connecting sleeve 422. After the annular workpiece is placed in the middle of the support plate 41, the annular workpiece is fitted onto the outer surface of the fixed rod 421. After the connecting sleeve 422 is fitted onto the outer surface of the fixed rod 421, the connecting sleeve 422 drives the pressure plate 423 to move vertically downward along the fixed rod 421 until the pressure plate 423 contacts the top of the annular workpiece. The connecting sleeve 422 can then be fixed by rotating the fixing bolt 424, thereby ensuring the fixing effect of the annular workpiece and preventing the annular workpiece from shaking and affecting the grinding effect when it is being ground.

[0036] The limiting mechanism 44 includes a slider 441, with a retaining bead 442 embedded in the top of the slider 441 and a slot 443 formed at the bottom of the slider 441. The upper end of the slider 441 and the retaining bead 442 are both located inside the groove 411, and the width of the slider 441 is the same as the width of the groove 411. The limiting mechanism 44 also includes a base plate 444, the bottom of which is fixedly connected to the top of the base 1. A fixing block 445 is fixedly connected to the central axis at the top of the base plate 444. The slider 441 communicates with the fixing block through the slot 443 formed at the bottom. 445 Sliding contact, the surface of the base plate 444 is provided with a placement groove 446, the left end of the placement groove 446 is provided with a placement groove 447, the width of the placement groove 446 and the placement groove 447 is the same, the placement groove 446 is provided with a connecting frame 448 inside, the bottom of the connecting frame 448 contacts the top of the base plate 444, the outer surface of the connecting frame 448 contacts the groove wall of the placement groove 446, and two connecting plates 449 are fixedly connected to the surface of the connecting frame 448, both of which are in contact with the surface of the slider 441;

[0037] A slider 441 and a retaining bead 442 are installed in the groove 411 at the bottom of the support plate 41. The slider 441 is connected to the fixing block 445 through the second groove 443 at the bottom. A connecting frame 448 and a connecting plate 449 are installed at the upper end of the base plate 444 to ensure the stability of the slider 441. This ensures that the support plate 41 can be prevented from deflecting when it is being polished by the polishing device 3.

[0038] When further grinding is needed on the annular workpiece after grinding by the grinding device 3, the connecting frame 448 is moved upward and slid into the placement groove 447. This allows the slider 441 to slide into the annular groove 412 through the retaining bead 442, thereby releasing the restriction of the slider 441 on the support plate 41. The support plate 41 can then be rotated by the vertical rod 43, facilitating further manual fine grinding of the annular workpiece.

[0039] The lifting mechanism 45 includes a fixed frame 455, which is fixedly connected to the surface of the slider 441. A limit frame 456 is fixedly connected to the upper end of the fixed frame 455. A connecting rod 2 453 is provided at the upper end of the fixed frame 455, and a slot 3 454 is opened at the lower end of the connecting rod 2 453. The limit frame 456 passes through the slot 3 454. A deflection plate 451 is fixedly connected to the top of the connecting rod 2 453. A connecting rod 1 452 is provided at the left end of the deflection plate 451. The connecting rod 2 453 is located inside the connecting groove 413, and the deflection plate 451 is located inside the slot 1 413. The deflection plate 451 is connected to the slot 1 413 via the connecting rod 2 453. The moving connection is achieved by installing a fixing frame 455 on the surface of the slider 441. After grinding the annular workpiece and removing the connecting sleeve 422, the slider 441 can be moved to slide along the fixing block 445 and drive the fixing frame 455 to slide. When the fixing frame 455 slides, it can squeeze the connecting rod 453, causing the connecting frame 453 to be squeezed upward under the restriction of the limiting frame 456. This allows the connecting rod 453 to drive the deflection plate 451 along the connecting groove 414 and the slot 413 to deflect the connecting rod 452 and lift the annular workpiece, thus preventing the annular workpiece from getting stuck on the surface of the support plate 41 and being difficult to remove.

[0040] In use, after placing the annular workpiece in the middle of the support plate 41, the annular workpiece is sleeved on the outer surface of the fixing rod 421. After the connecting sleeve 422 is sleeved on the outer surface of the fixing rod 421, the connecting sleeve 422 drives the pressure plate 423 to move vertically downward along the fixing rod 421 until the pressure plate 423 contacts the top of the annular workpiece. Then, the connecting sleeve 422 can be fixed by rotating the fixing bolt 424, thereby ensuring the fixing effect of the annular workpiece and preventing the annular workpiece from shaking and affecting the grinding effect when it is being ground.

[0041] Furthermore, a slider 441 and a retaining bead 442 are installed in the groove 411 opened at the bottom of the support plate 41. The slider 441 is connected to the fixing block 445 through the second groove 443 opened at the bottom. The connecting frame 448 and the connecting plate 449 are installed at the upper end of the base plate 444 to ensure the stability of the slider 441. This ensures that the support plate 41 can be prevented from deflecting when it is being polished by the polishing device 3.

[0042] When further grinding is required on the annular workpiece after grinding by the grinding device 3, the connecting frame 448 is moved upward and slid into the placement groove 447. This allows the slider 441 to slide into the annular groove 412 through the retaining bead 442, thereby releasing the slider 441 from the restriction of the support plate 41. The support plate 41 can then be rotated by the vertical rod 43, which facilitates further manual fine grinding of the annular workpiece.

[0043] By installing a fixing frame 455 on the surface of the slider 441, after the annular workpiece is ground and the connecting sleeve 422 is removed, the slider 441 can be moved so that the slider 441 slides along the fixing block 445 and drives the fixing frame 455 to slide. When the fixing frame 455 slides, it can squeeze the connecting rod 453, so that the connecting frame 453 is squeezed upward under the restriction of the limiting frame 456. Thus, the connecting rod 453 can drive the deflection plate 451 along the connecting groove 414 and the slot 413 to deflect the connecting rod 452 to help lift the annular workpiece, thus avoiding the situation where the annular workpiece is stuck on the surface of the support plate 41 and is difficult to remove.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
