Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a secondary chip removal mechanism suitable for a low-chassis precision engraving machine. Background Art

[0002] The secondary chip removal mechanism collects the metal or non-metallic waste chips discharged from the base, separates the coolant and waste chips, and then discharges them in a centralized manner. In the prior art, the secondary chip removal mechanism of low-base precision engraving machines is often set up relatively wide, seriously occupying the space behind the machine tool. In addition, the chip removal direction is not adjustable, which is not convenient for accommodating the spatial layout of different workshops. Utility Model Content

[0003] The problem that the utility model solves is that in the prior art, the secondary chip removal mechanism of the low-chassis precision engraving machine is easily set to be relatively wide, which seriously occupies the space behind the machine tool, and the chip removal direction is not adjustable, which is inconvenient to cope with the space layout problem of different workshops. A secondary chip removal mechanism suitable for low-chassis precision engraving machines is provided, which occupies less rear space and has flexible chip removal direction.

[0004] The utility model is realized through the following technical scheme: a secondary chip removal mechanism suitable for a low-chassis precision engraving machine, including an oil tank, the oil tank is L-shaped, and is attached to both sides of the machine tool base, wherein the first side of the oil tank is located below the chip removal port of the machine tool base, and the second side is located on the side of the machine tool, and the second side of the oil tank is installed with an oil pump, an oil-water separator, and a liquid level meter. The first side of the oil tank is provided with a semicircular groove plate, and a screw is provided in the groove plate, and the screw can be driven to rotate by a motor. The screw is what we often call an auger. The rotation of the screw can push the waste chips to move in the groove plate, thereby providing driving force for chip removal. The upper edges of both sides of the groove plate are inclined with chip guard plates, and the chip guard plates are provided with a plurality of holes. When the waste chips accumulate to the height of the chip guard plates, the excess coolant will flow out of the holes to separate the coolant and waste chips in advance. The end of the groove plate away from the motor is connected to a chip removal pipe, and the chip removal pipe includes a first pipe , a second tube, a flange cover, and a pressure plate, the first tube and the second tube are both bent at 90°, the upper end of the first tube is provided with a first flange, the lower end of the second tube is provided with a flange, and the lower end of the second tube is sleeved with a pressure plate and a flange cover, the pressure plate and the flange cover are provided with through holes with the same parameters as the first flange, and fasteners are provided to penetrate the flange cover, the pressure plate, and the first flange for fastening connection, a distance portion is provided between the first flange and the flange cover, the distance portion can ensure that the distance between the first flange and the flange cover is greater than the thickness of the pressure plate and the flange, and several springs are provided between the pressure plate and the flange cover, the springs are used to squeeze the flange between the pressure plate and the first flange. In this scheme, the flange of the second tube is squeezed against the first flange by the pressure plate and fixed by friction, but after applying a larger external force, the second tube can be rotated along the vertical axis at the flange to a suitable position, which is convenient for adjusting the angle. In addition, the oil tank of this solution adopts an L-shaped layout, which occupies a small area behind the machine tool and only occupies part of the side space. However, there is generally enough space on the sides of the machine tool. Therefore, this solution makes rational use of the side space and improves the utilization efficiency of space.

[0005] Furthermore, in order to prevent the spring from deviating, the flange cover and the pressure plate are provided with recessed grooves at the positions in contact with the spring, and the two ends of the spring are placed in the recessed grooves.

[0006] Furthermore, in order to facilitate installation, the spring is sleeved on the fastener, and during installation, it only needs to be sleeved outside the fastener without the need for additional positioning.

[0007] Furthermore, in order to achieve spacing, the spacing portion is a circular tube on the edge of the flange cover that extends outward perpendicularly to the flange plane, and the circular tube is provided with a positioning step for positioning the first flange.

[0008] Furthermore, in order to reduce the friction between the pressure plate and the flange, the material of the surface where the pressure plate contacts the flange is polytetrafluoroethylene. Therefore, when the second tube is rotated, the second tube can be pulled outward to reduce the contact pressure between the flange and the first flange, or the flange can be moved away from the first flange. At this time, when the second tube is rotated again, the friction between the flange of the second tube and the polytetrafluoroethylene is very small, and the friction between the flange and the first flange is reduced or zero, which makes it more convenient to rotate.

[0009] Furthermore, in order to facilitate positioning, the flange and the first flange are provided with matching positioning protrusions and positioning grooves on the corresponding contact surfaces. The positioning protrusions and positioning grooves adopt a relatively flat structure, so that the second tube can be rotated by pulling the second tube outward or using a sufficiently large torque, thereby avoiding the squeezing force of the waste chips in the second tube from affecting the position of the second tube.

[0010] Furthermore, a trolley is provided. The trolley can be arranged in parallel along the first side or along the second side, and can be arranged according to the outlet position of the second pipe.

[0011] The beneficial effects of the utility model are:

[0012] 1. The oil tank of the utility model adopts an L-shaped layout, which occupies a small area behind the machine tool and only occupies part of the side space. However, there is generally enough space on the side of the machine tool. Therefore, this solution makes rational use of the side space and improves the utilization efficiency of space.

[0013] 2. The chip removal pipe of the utility model includes a first pipe, a second pipe, a flange cover, and a pressure plate. The flange of the second pipe is pressed against the first flange by the pressure plate and is fixed by friction. However, after applying a large external force, the second pipe can be rotated along the vertical axis of the flange to a suitable position, which is convenient for adjusting the angle and can be reasonably adjusted according to the space on the workshop site.

[0014] 3. The material of the surface where the pressure plate contacts the flange of the utility model is polytetrafluoroethylene. Therefore, when the second tube is rotated, the second tube can be pulled outward to reduce the contact pressure between the flange and the first flange, or the flange can be moved away from the first flange. At this time, when the second tube is rotated again, the friction between the flange of the second tube and the polytetrafluoroethylene is very small, and the friction between the flange and the first flange is reduced or zero, which makes rotation more convenient.

[0015] 4. The flange and the first flange of the present invention are provided with matching positioning protrusions and positioning grooves on the corresponding contact surfaces, so that the second tube needs to be pulled outward before it can be rotated, thereby avoiding the squeezing force of the waste chips in the second tube from affecting the position of the second tube.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-4As shown, a secondary chip removal mechanism suitable for a low-chassis precision engraving machine includes an oil tank 1. The oil tank 1 is L-shaped and is attached to both sides of the machine tool base. The first side of the oil tank 1 is located below the chip removal port of the machine tool base, and the second side is located on the side of the machine tool. An oil pump, an oil-water separator, and a liquid level gauge are installed on the second side of the oil tank 1. A semicircular groove plate 2 is provided on the first side of the oil tank 1. A screw 3 is provided in the groove plate 2. The screw 3 can be driven to rotate by a motor. The screw 3 is what we often call a screw. Dragon, the rotation of the screw 3 can push the waste chips to move in the groove plate 2, thereby providing a driving force for chip removal. The upper edges of both sides of the groove plate 2 are inclined with chip guard plates 4, and the chip guard plates 4 are provided with a number of holes. When the waste chips accumulate to the height of the chip guard plates 4, the excess coolant will flow out of the holes to achieve early separation of the coolant and waste chips. The end of the groove plate 2 away from the motor is connected to a chip removal pipe, which includes a first pipe 5, a second pipe 6, a flange cover 7, and a pressure plate 8. The first pipe 5 and the second pipe 6 The flange 17 is provided at the bottom of the second tube 6, and the flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. The flange 17 is provided at the bottom of the second tube 6. Figure 3-4 As shown, the second pipe 6 can be rotated 90 degrees to face either side. Furthermore, the oil tank 1 of this solution adopts an L-shaped layout, which occupies a small area behind the machine tool and only occupies part of the side space. Since machine tools generally have ample space on the sides, this solution makes rational use of the side space and improves space utilization efficiency.

[0025] In practical applications, such as Figure 5-6 As shown, in order to prevent the spring 10 from deviating, the flange cover 7 and the pressure plate 8 are provided with recessed grooves 11 at the locations in contact with the spring 10 , and both ends of the spring 10 are placed in the recessed grooves 11 .

[0026] In practical applications, such as Figure 5-6 As shown, for the convenience of installation, the spring 10 is sleeved on the fastener 9. During installation, it only needs to be sleeved outside the fastener 9 without additional positioning.

[0027] In practical applications, such as Figure 5-6 As shown, in order to achieve spacing, the spacing portion 14 is a circular tube extending outward perpendicularly to the flange plane at the edge of the flange cover 7 , and the circular tube is provided with a positioning step for positioning the first flange 16 .

[0028] In actual application, in order to reduce the friction between the pressure plate 8 and the flange 17, the material of the contact surface of the pressure plate 8 and the flange 17 is polytetrafluoroethylene. Therefore, when the second tube 6 is rotated, the second tube 6 can be pulled outward to reduce the contact pressure between the flange 17 and the first flange 16, or the flange 17 can be moved away from the first flange 16. At this time, when the second tube 6 is rotated again, the friction between the flange 17 of the second tube 6 and the polytetrafluoroethylene is very small, and the friction between the flange 17 and the first flange 16 is reduced or zero, which makes it more convenient to rotate.

[0029] In practical applications, such as Figure 5-6 As shown, in order to facilitate positioning, the flange 17 and the first flange 16 are provided with matching positioning protrusions 12 and positioning grooves 13 on the corresponding contact surfaces. The positioning protrusions 12 and the positioning grooves 13 adopt a relatively flat structure, so that the second tube 6 can be rotated by pulling it outward or using a sufficiently large torque, thereby avoiding the squeezing force of the waste chips in the second tube 6 from affecting the position of the second tube 6.

[0030] In practical applications, such as Figure 3-4 As shown, a trolley 15 is also provided. The trolley 15 can be arranged in parallel along the first side or along the second side, and can be arranged according to the outlet position of the second pipe 6 .

[0031] To sum up, the secondary chip removal mechanism suitable for a low-chassis precision engraving machine described in the present invention reduces the occupancy of the space behind the machine tool, makes rational use of the side space, improves the utilization efficiency of the space, and the chip removal position of the chip removal pipe is adjustable to meet the requirements of different workshop layouts.
