Description

Technical Field

[0001] This utility model relates to the field of vertical grinding machine technology, specifically to a cooling fluid spraying device for the grinding head of a vertical grinding machine. Background Technology

[0002] In existing vertical grinding machines, the coolant spray structure of the grinding head is fixed to the grinding head, and the relative position between the coolant nozzle and the grinding head is fixed. During workpiece machining, the coolant nozzle moves with the grinding head, spraying coolant onto the workpiece to cool it. The cooling effect directly affects the machining accuracy of the workpiece. To improve the cooling effect, the desired spraying position is at the contact point between the grinding wheel and the workpiece.

[0003] Reference Figure 1 During the machining process, the grinding wheel moves relative to the workpiece surface, and the contact position between the grinding wheel and the workpiece is changing. Especially for some irregular curved surfaces, since the relative position between the coolant nozzle and the grinding wheel of the existing vertical grinding machine is fixed, it is impossible to adjust the coolant spray position, resulting in poor cooling effect.

[0004] Furthermore, for vertical grinding machines equipped with tool magazines that can automatically change tools, when changing to a larger grinding wheel, the existing grinding head coolant spray structure will interfere with the tool changing position, making it impossible to complete the automatic tool changing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling fluid follow-up spraying device for a vertical grinding machine, which can easily adjust the cooling fluid spraying position, thereby improving the workpiece cooling effect; and for grinding machines with automatic tool changing function, the spraying mechanism moves to avoid the tool changing position when changing the grinding wheel, ensuring the smooth completion of automatic tool changing.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A grinding head coolant follow-up spraying device for a vertical grinding machine is provided, which is installed on the spindle assembly of the grinding head; the device includes a rotation mechanism, a horizontal movement mechanism and a spraying mechanism;

[0008] The rotating mechanism includes a rotating bracket, a first motor, a fixed gear ring, a first gear, and a toothed belt; the rotating bracket is rotatably connected to the spindle sleeve of the spindle assembly, enabling the rotating bracket to rotate around the spindle inside the spindle sleeve; the fixed gear ring is fixedly fitted onto the spindle sleeve; the first motor is fixed to the rotating bracket; the first motor is driven by the first gear, and the first gear is driven by the fixed gear ring via the toothed belt.

[0009] The horizontal movement mechanism includes a base, a sliding plate, and a second motor; the base is fixed on the rotating bracket, and the second motor can drive the sliding plate to move horizontally relative to the base.

[0010] The spraying mechanism is fixed to the slide plate.

[0011] Furthermore, the rotating bracket includes a rotating ring and a first fixed bracket. The rotating ring is fitted outside the main shaft sleeve and is rotatably connected to the main shaft sleeve. The first fixed bracket is fixedly connected to the rotating ring, and the first motor is fixed on the first fixed bracket.

[0012] Furthermore, the horizontal moving mechanism also includes a second fixed bracket, which is fixedly connected to the rotating ring, and the base is fixed on the second fixed bracket.

[0013] Furthermore, two slide rails are horizontally arranged on the base, and rollers that cooperate with the slide rails are provided on the slide plate.

[0014] Furthermore, the horizontal moving mechanism also includes a second gear, the second motor is fixed on the slide plate, and one of the slide rails on the base is provided with a horizontal tooth surface. The second motor drives the second gear to rotate, and the second gear cooperates with the horizontal tooth surface, thereby driving the slide plate to move horizontally relative to the base.

[0015] Furthermore, two limiting members are fixed on the second fixed bracket. The two limiting members are located on both sides of the horizontal direction of the base, and the slide plate is limited in its travel by the limiting members on both sides during horizontal movement.

[0016] Furthermore, there are two rotating rings, which are respectively disposed on the upper and lower parts of the main shaft sleeve. Both the first fixed bracket and the second fixed bracket are provided with two connecting arms, which are fixedly connected to the two rotating rings respectively.

[0017] Furthermore, the spraying mechanism includes a water pipe and a nozzle. The water pipe is fixedly connected to the slide plate. One end of the water pipe is connected to a coolant supply pipe, and the other end of the water pipe is connected to the nozzle.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention relates to a vertical grinding machine where the grinding head coolant is sprayed via a rotating mechanism. The spraying mechanism rotates around the grinding head's spindle, allowing the spray nozzle to adjust its position around the grinding wheel in a circle. A horizontal movement mechanism further adjusts the spraying mechanism's horizontal position. After the nozzle's circumferential position is adjusted, its horizontal position can be adjusted to ensure the spray is always aligned with the contact point between the grinding wheel and the workpiece, guaranteeing effective cooling. For grinding machines with automatic tool changers, the rotating mechanism moves the spraying mechanism away from the tool changer side during wheel replacement, preventing interference and ensuring smooth automatic tool changing.

[0027] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0028] The grinding head of the vertical grinding machine includes a spindle motor (not shown in the figure), a spindle assembly, and a grinding wheel (not shown in the figure). The spindle assembly includes a spindle sleeve 1 and a spindle, with the spindle assembled inside the spindle sleeve. The spindle motor is mounted at the upper end of the spindle assembly and drives the spindle to rotate. The grinding wheel is mounted at the lower end of the spindle assembly, and the spindle drives the grinding wheel to rotate.

[0029] like Figure 2 , Figure 3 As shown, in this embodiment, the grinding head coolant follow-up spraying device is mounted on the grinding head spindle assembly. The grinding head coolant follow-up spraying device includes a rotating mechanism 2, a horizontal moving mechanism 3, and a spraying mechanism 4. The rotating mechanism 2 is mounted on the spindle assembly, the horizontal moving mechanism 3 is mounted on the rotating mechanism 2, and the spraying mechanism 4 is mounted on the horizontal moving mechanism 3. The rotating mechanism 2 can drive the horizontal moving mechanism 3 and the spraying mechanism 4 to rotate around the spindle, and the horizontal moving mechanism 3 can drive the spraying mechanism 4 to move horizontally left and right. By adjusting the circumferential and horizontal positions of the spraying mechanism 4 through the rotating mechanism 2 and the horizontal moving mechanism 3, the spraying position of the coolant can be adjusted to ensure the cooling effect.

[0030] like Figure 4 and Figure 5 As shown, Figure 5 The toothed belt 24 has been removed. In a specific embodiment, the rotating mechanism includes a rotating bracket, a first motor, a fixed gear ring 26, a first gear 27, and a toothed belt 24. The rotating bracket includes a rotating ring and a first fixed bracket 25. There are two rotating rings, namely an upper rotating ring 21 and a lower rotating ring 22. The upper rotating ring 21 and the lower rotating ring 22 are respectively fitted onto the upper and lower parts of the main shaft sleeve 1, and the upper rotating ring 21 and the lower rotating ring 22 are rotatably connected to the main shaft sleeve 1. It can be understood that a bearing is provided between the rotating ring and the main shaft sleeve 1. The rotating ring can rotate around the main shaft, that is, the rotating ring is coaxial with the main shaft. The first motor is located inside the first motor cover 23, and the first gear 27 is located on the top of the first motor cover 23. The first gear 27 is fixedly connected to the output shaft of the first motor. The fixed gear ring 26 is fixedly installed on the main shaft sleeve, located above the upper rotating ring 21. The first gear 27 and the fixed gear ring 26 are connected by a toothed belt 24. The first fixed bracket 25 has connecting arms at both ends, and the two connecting arms are fixedly connected to the upper rotating ring 21 and the lower rotating ring 22 respectively. The first motor and the first motor cover 23 are fixed on the first fixed bracket 25.

[0031] The rotation mechanism operates as follows: the first motor drives the first gear 27 to rotate, and the first gear 27 meshes with the toothed belt 24, which in turn meshes with the fixed toothed ring 26. Since the fixed toothed ring 26 cannot rotate, the toothed belt 24 is tensioned, and the upper rotating ring 21 and the lower rotating ring 22 can rotate. Consequently, the first gear 27 rotates around the fixed toothed ring 26 under the reaction force of the toothed belt 24. In other words, the first gear 27 drives the first motor and the rotating support to rotate around the main shaft.

[0032] like Figure 5 and Figure 6 As shown, in a specific embodiment, the horizontal movement mechanism includes a second fixed bracket 34, a base 33, a sliding plate 32, and a second motor. The second motor is located inside a second motor cover 31. The spraying mechanism 4 is fixed to the sliding plate 32. Connecting arms are provided at both ends of the second fixed bracket 34, and the two connecting arms are respectively fixedly connected to the upper rotating ring 21 and the lower rotating ring 22. The base 33 is fixed to the second fixed bracket 34. It can be understood that the rotation of the upper rotating ring 21 and the lower rotating ring 22 can drive the second fixed bracket 34 to rotate.

[0033] Two parallel slide rails 331 are horizontally arranged on the base 33. Four rollers 321, which mesh with the slide rails 331, are rotatably connected to the slide plate 32. Two rollers 321 mesh with the upper slide rail 331, and the other two rollers mesh with the lower slide rail 331. The meshing of the rollers 321 with the slide rails 331 allows the base 33 and slide plate 32 to slide together. A second gear 36 is provided between the base 33 and slide plate 32. A second motor and a second motor cover 31 are fixed to the slide plate 32. The second motor is connected to the second gear 36 for transmission. One of the two slide rails 331 has a horizontal toothed surface 3311. This horizontal toothed surface 3311 can be directly machined onto the slide rail 331, or a rack can be fixed onto the slide rail 331. The second gear 36 meshes with the horizontal toothed surface 3311.

[0034] The movement process of the horizontal moving mechanism is as follows: the second motor drives the second gear 36 to rotate, and the second gear 36 meshes with the horizontal tooth surface 3311 on the slide rail 331, so that the second motor and the slide plate 32 can move horizontally with the cooperation of the roller 321 and the slide rail 331.

[0035] Preferably, two limiting members 35 are fixed on the second fixed bracket 34. The two limiting members 35 are located on both sides of the horizontal direction of the base 33. During the horizontal movement of the slide plate 32, the travel is limited by the limiting members 35 on both sides. In other words, when the slide plate 32 moves horizontally to the left to the extreme position, it will be blocked by the left limiting member 35, and when the slide plate 32 moves horizontally to the right to the extreme position, it will be blocked by the right limiting member 35.

[0036] The spraying mechanism includes an inlet valve 43, a water pipe 41, and a nozzle 42. The inlet valve 43 is fixed on the slide plate 32. The inlet of the inlet valve 43 is connected to the coolant supply pump through a pipeline. The outlet of the inlet valve 43 is connected to the water pipe 41. The lower end of the water pipe 41 is connected to the nozzle 42.
