Description

Technical Field

[0001] The utility model belongs to the field of cooling systems for vertical grinders, and in particular relates to a complete tooling set for fixing a water spray pipe. Background Art

[0002] The traditional vertical grinder water pipe is connected from the top of the machine tool to the grinding wheel 7 ( Figure 1 ); When the coolant is sprayed on the grinding wheel from the water spray pipe, the reaction force generated by the coolant spraying on the grinding wheel due to the long and insufficient rigidity of the water spray pipe not only easily causes an angle between the water spray pipe and the grinding wheel, but also offsets part of the water pressure, thus reducing the cooling and flushing capabilities of the coolant. The distance between the water spray pipe and the grinding wheel is not easy to control. When the size of the grinding wheel changes, the water spray pipe can only be forced to bend and deform to adapt to the size of the different grinding wheels, making the cooling water pressure uneven in the entire axial direction of the grinding wheel, which also reduces the cooling and flushing capabilities of the coolant. Utility Model Content

[0003] The problems to be solved are: first, the problem that the water spray pipe cannot be rigidly fixed; second, the problem that the distance between the water spray pipe and the grinding wheel is difficult to control.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a complete set of tooling for fixing a water spray pipe, which is used to be sleeved on the water spray pipe and fixed on the main shaft of a vertical mill, including a flange and a clamp. The flange is sleeved on the outside of the main shaft of the vertical mill, and the clamp is connected to the flange. The clamp can be sleeved on the outside of the water spray pipe. The clamp includes a clamping part and a connecting part. The clamping part and the connecting part hold the water spray pipe tightly and the clamping part and the connecting part are detachably connected. The connecting part is connected to the flange and is provided with a strip hole.

[0005] Preferably, the flange consists of two symmetrical parts, which are connected by hexagon socket bolts and are provided with flange threaded holes.

[0006] Preferably, one side surface of the connecting portion is an arc surface, and the radius of the arc surface is the same as the outer diameter of the vertical mill spindle.

[0007] Preferably, an arc convex portion is provided at the end of the connecting portion connected to the flange.

[0008] Preferably, the bottom end of the water spray pipe is flush with the bottom end of the grinding wheel and is sealed, and a water spray gap is provided at one end close to the grinding wheel, and the height of the water spray gap is not less than the height of the grinding wheel.

[0009] Compared with the prior art, the utility model provides a complete set of tooling for fixing a water spray pipe, which has the following beneficial effects:

[0010] The flange sleeve is arranged on the outside of the vertical mill spindle and the height can be adjusted as needed so that the gap of the water spray pipe can match different grinding wheels; the water spray pipe can be rotated in the clamp to adjust the position of the water spray port. At the same time, since the connection part is designed as an arc, it is not easy to interfere with the inner hole of the workpiece; the setting of the arc surface and the arc convex part of the connection part can adjust the distance between the water spray pipe and the grinding wheel to meet different operation requirements.

[0018] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0019] A complete set of tooling for fixing a water spray pipe comprises a flange 2 and a clamp 3. The flange 2 is divided into two symmetrical parts, which are connected together by hexagon socket bolts and sleeved on the outside of a vertical mill main shaft 1. The inner diameter of the flange 2 is the same as the outer diameter of the vertical mill main shaft 1. The flange 2 can be installed at any position of the vertical mill main shaft 1 and can be adjusted up and down autonomously. The clamp 3 is installed on the upper end surface of the flange 2, and a flange threaded hole 21 is provided on the flange 2. The clamp 3 sleeved on the outside of the water spray pipe 6 is divided into a clamping part 31 and a connecting part 32. The clamping part 31 and the connecting part 32 are detachably connected by a hexagon socket bolt and a bolt hole. The connecting part 32 is L-shaped, and one end of the clamping part 31 is connected to one end of the transverse part of the connecting part 32. An arc groove A311 is provided at the other end of the clamping part 31. Opposite to the arc groove A311 is an arc groove B324. The arc groove B324 is located at the other end of the connecting part 32 in the transverse direction. The inner diameters of the arc groove A311 and the arc groove B324 are the same, and the arc groove A311 and the arc groove B324 form a channel for the water spray pipe 6 to pass through the clamp 3, so that the clamping part 31 and the connecting part 32 can hold the water spray pipe 6 tightly. The longitudinal outer end of the connection part 32 is connected to the flange 2, and the longitudinal part of the connection part 32 is provided with a strip hole 323, the longitudinal length of the strip hole 323 along the connection part 32 is greater than the transverse width, and the strip hole 323 and the flange threaded hole 21 overlap longitudinally to form a bolt channel connecting the flange 2 and the clamp 3. The water spray pipe 6 is sleeved in the clamp 3, the clamp 3 is fixed on the flange 2, and the flange 2 is sleeved on the outside of the vertical mill spindle 1 and the height is adjustable, thereby realizing the improvement of the fixing rigidity of the water spray pipe 6, and it will not cause rebound with the spraying of the coolant like the original equipment.

[0020] In production, the size of the grinding wheel 7 often changes. The increase or decrease in the outer diameter of the grinding wheel 7 will lead to an improper distance between the water pipe 6 and the grinding wheel 7, affecting the cooling and flushing effects. Therefore, we need to adjust the distance between the water pipe 6 and the grinding wheel 7. Therefore, we have made adjustments to the clamp 3. One side of the connecting portion 32 is an arc surface 321. The radius of the arc surface 321 is the same as the outer diameter of the vertical mill spindle 1 and they are co-centered. In this way, when the outer diameter of the grinding wheel 7 is small, the arc surface 321 can fit on the outside of the vertical mill spindle 1, thereby shortening the distance between the water pipe 6 and the grinding wheel 7; the end of the connecting portion 32 close to the vertical mill spindle 1 is provided with an arc convex portion 322. The arc convex portion 322 and the arc surface 321 are not on the same side of the center, and in order to The two have a smooth transition. We make the arc convex part 322 circumscribe the arc surface 321. When the outer diameter of the grinding wheel 7 is large, the arc convex part 322 is close to the outer side of the vertical mill main shaft 1; the longitudinal overlap position of the strip hole 323 and the flange threaded hole 21 changes to adjust the distance between the water spray pipe 6 and the grinding wheel 7. No matter which part of the connecting part 32 is close to the outer side of the vertical mill main shaft 1, the fixing method is to fix it by passing the bolt through the strip hole 323 and the flange threaded hole 21 directly below the strip hole 323.

[0021] The water spray pipe 6 passes through the channels of the arc groove A311 and the arc groove B324, and the bottom end of the water spray pipe 6 is flush with the bottom end of the grinding wheel 7, and the bottom end of the water spray pipe 6 is sealed. Generally, a small hole is provided at the overlapping portion of the water spray pipe 6 and the grinding wheel 7, but the small hole is easily blocked, affecting the use. The utility model provides a water spray gap at one end of the water spray pipe 6 close to the grinding wheel 7, and the height of the water spray gap is not less than the height of the grinding wheel 7, so as to ensure that every part of the grinding wheel 7 is washed.

[0022] The installation steps of the utility model are as follows: first, install the flange 2, install the two symmetrical parts of the flange 2 on the outside of the vertical mill spindle 1, and tighten the two parts of the flange 2 through the M8 hexagon socket bolts at the interface, so that the flange 2 is tightly held on the outer circle of the vertical mill spindle 1; secondly, install the water spray pipe 6, put the water spray pipe 6 in the channel of the water spray pipe 6 between the clamping part 31 and the connecting part 32, estimate the approximate direction position of the water spray gap and the relative angle with the grinding wheel 7, adjust the water spray pipe 6, and tighten the water spray pipe 6 through the M8 hexagon socket bolts at the interface. The angle bolts fix the clamping part 31 and the connecting part 32 together so that the clamp 3 is sleeved on the outside of the water spray pipe 6; finally, install the clamp 3, place the connecting part 32 on the end face of the flange 2, slightly rotate it to adjust the distance between the water spray pipe 6 and the grinding wheel 7, and then fix the clamp 3 on the flange 2 with the M8 hexagon socket bolts 5; check the direction of the water spray gap of the water spray pipe 6 and the relative angle with the grinding wheel 7. If it is not appropriate, loosen the M8 hexagon socket bolts 4 and adjust it to a suitable position.

[0023] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
