Description

A BMT center-outlet water-powered tool holder Technical Field

[0001] This invention relates to the field of machining tool holder technology, specifically a BMT center-outlet water-powered tool holder. Background Technology

[0002] A powered tool holder refers to a tool holder mounted on a powered tool turret and driven by a servo motor. This type of tool holder is generally used in mill-turning machines, and in a few cases, it can also be used in machining centers with powered tool turrets. In next-generation mill-turning machines, whether it's the indexing C-axis head, sub-spindle, or Y-axis, a powered tool turret is essential to achieve mill-turning functionality. Therefore, a high-performance, high-precision C-axis powered tool turret will further perfect next-generation mill-turning machines.

[0003] The following problems exist in the implementation of a certain technology related to a BMT (Body-Mounted Tunneling) center-outflow water-powered tool holder:

[0004] 1. The drive shaft mechanism includes a fixed bushing fixed in the drive shaft mounting hole, a drive shaft body rotatably mounted inside the fixed bushing, a second bevel gear connected to the first bevel gear at the inner end of the drive shaft body, a shaft cap fixed at the outer end of the drive shaft body, and a water nozzle on the side wall of the side housing. During implementation, since the water nozzle spray position is located on the side of the power blade cutting position, it cannot directly cool and lubricate the cutting position. Generally, a center-outlet power blade holder is used for this purpose. However, the center-outlet power blade holder can generally only cool and lubricate the end point of the power blade during the cutting process, and cannot cool and lubricate all contact surfaces. Under long-term cutting conditions, the blade head needs to be replaced in a short period of time, and the blade head has a short service life.

[0005] 2. During operation, the center-outlet power cutter holder may experience water splashing and material contamination. Generally, expensive cleaning equipment or manual cleaning with a cleaning cloth is used. This not only consumes manpower and equipment costs, but also requires a long cleaning time, which greatly reduces the working efficiency of the power cutter holder. Summary of the Invention

[0013] (I) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a BMT center-outlet power cutter holder, which has the following beneficial effects:

[0015] 1. The BMT center-outlet power cutter holder, along with its flow control unit and flushing unit, can work together to select two water outlet models: a center-outlet mode and a common-outlet mode. These two modes better help the power cutter holder control the temperature and lubricate the cutter head, preventing the problem of the cutting end temperature being controlled by the water flow while the outer temperature of the cutting end is not effectively improved. The flow control unit and flushing unit can effectively reduce the working temperature and increase the lubrication level, which not only saves equipment and labor costs but also greatly improves the working efficiency of the cutter head and extends its service life.

[0016] 2. The BMT center-outlet power cutter holder, through the operation of the cleaning unit, can clean the material surface after the power cutter head has finished its work, preventing the problem of residue and cooling lubricating water mixture from soiling the material's outer surface. This greatly saves the cost of cleaning using equipment and manpower, increases the mechanization rate, and significantly improves the cleaning efficiency.

[0017] 3. The BMT center outlet power tool holder, through the operation of the emergency unit, can prevent the special situation of sprayed cooling and lubricating water splashing onto the outer surface of the power tool holder during operation. If not treated for a long time, impurities will easily accumulate on the outer surface of the power tool holder, affecting the normal operation of the power tool holder. The emergency unit can avoid the problem of splash contamination on the outer surface of the power tool holder during operation, while saving the cost of manual cleaning, greatly reducing the probability of contamination, and avoiding cleaning.

[0034] Please refer to Figure 4. The diversion control unit 5 includes a diversion controller 501. A control gear 502 is fixedly connected to the output end of the diversion controller 501. An auxiliary gear 503 is meshed with the side end of the control gear 502. A diversion baffle 504 is fixedly connected to the inner end of the auxiliary gear 503. An elastic stop block 505 is slidably connected to the top end of the diversion baffle 504. Three gear slots 506 are respectively opened on the top end of the elastic stop block 505.

[0035] In summary, this invention first installs the power cutter head, ensuring that the outer ends of the power cutter head and the auxiliary rod 207 are of the same length. The outer end of the power cutter head is precisely flushed by the outer flushing gun 201. Then, the cutter holder body 101 is opened to begin operation. When the cutting depth is shallow, the diversion control unit 5 can adjust the gear according to a predetermined setting. The diversion controller 501 rotates the control gear 502, which in turn drives the auxiliary gear 503, causing the diversion baffle 504 to rotate to the center water outlet position. At this time, the water flow in the diversion channel 103 is introduced to the top by the diversion baffle 504 for center water outlet, and cooling and lubricating water is sprayed out from the outer end of the power cutter head. When the cutting depth is very deep and water needs to be sprayed simultaneously from the power cutter head port and the outer side for cooling and lubrication, the diversion controller 501 controls the diversion baffle 504 to make water outlet simultaneously from the top and bottom diversion channels 103, thus achieving the same cutting depth and outer surface treatment. The cooling and lubrication process completes the cutting process. Simultaneously, as the outer flushing gun 201 sprays precisely onto the end point of the power cutter head, the auxiliary rod 207 moves inward with the cutter head as the cutting depth increases. This movement drives the bottom track 205 to rotate, which in turn drives the bottom wheel 206 to rotate. The rotation is then transmitted to the upper rotating wheel 203 via the transition wheel 204, which in turn drives the friction track 202 to rotate. This causes the outer flushing gun 201 and the auxiliary rod 207 to move synchronously. Thus, even as the power cutter head reaches deeper, the movement of the auxiliary rod 207 increases the flushing depth of the outer flushing gun 201, ensuring that the outer flushing gun 201 always flushes the intersection of the material's outer surface and the power cutter head. This simultaneously cools and lubricates both the inside and outside of the power cutter head. The control motor 402 and the main body 1 of the device have a fixed connection.

[0036] In this invention, when the water outlet at the top center is opened, due to the high pressure, the control motor 402 will detect the water pressure and flow rate. Under this water pressure and flow rate, the power blade will move away from the material to provide cleaning space. The cleaning fan blade 401 will be temporarily stopped from rotating without obstructing the water flow. When the water pressure and flow rate decrease to the working range, the control motor 402 will no longer restrict the cleaning fan blade 401. The cleaning fan blade 401 will rotate with the water flow, thereby driving the power bevel gear 403, which in turn drives the transmission bevel gear 404 to rotate, which in turn drives the top cleaning intermittent gear 405 to rotate, which in turn drives the cleaning gear 406 to rotate, which in turn drives the cleaning support rod 408 to rotate, which in turn drives the cleaning telescopic plate 410 to extend and swing, which in turn drives the cleaning cylinder 411 to reciprocate cleaning the outer surface of the material.

[0037] In this invention, when the flushing unit 2 is activated for flushing, a special situation may occur where the sprayed cooling and lubricating water splashes onto the outer surface of the power tool holder due to prolonged lack of cleaning. Furthermore, if left untreated, impurities may accumulate on the outer surface of the power tool holder, affecting its normal operation. In this case, an emergency unit can be used to prevent splashing. The emergency servo motor 301 is switched on and off by water flow, utilizing the conductivity of water. When there is no water flow, the emergency unit does not activate and resets. When water flow occurs, the emergency servo motor 301 is activated due to the conductivity of water. Here, conductivity is only used to activate the switch. The emergency servo motor has a short operating time and is a DC motor, which is harmless to the circuit and personnel. After the emergency servo motor 301 is activated, it controls the emergency protrusion 302 to rotate. The rotation of the emergency protrusion 302 causes the protruding position to slide and fit against the emergency rotating plate 303, which in turn causes the emergency rotating plate 303 to rotate, thereby closing the front emergency baffle 307 and blocking the splashed cooling water. When the power knife holder does not move, the emergency unit servo motor returns to its original position, the emergency spring 305 assists the emergency rotating plate 303 to reset, and then the emergency baffle 307 resets, completing the emergency splash protection work.
