Detailed Description
In order to make the objects, technical schemes and advantages of the present invention more clear, the self-sealing cup-lid type tool magazine of the present invention will be further described in detail by the following embodiments and with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
As shown in fig. 1, 2 and 3, the self-sealing cup-lid type tool magazine is provided with a positioning shaft 330 at the lower part of a cutter bar 310, the positioning shaft 330 is provided with a clamping groove 520, and the clamping groove 520 is composed of a guide inclined plane 524, a vertical groove 522, a cutter hanging groove 521 and a spiral groove 523. The positioning shaft 330 is inserted into the positioning hole 210 of the cup cover 200, the pin 510 supports the cutter hanging groove 521 to stably fix the cutter in the center of the cup cover 200, and the cutter 320 is fixed at the lowest end of the cutter bar 310. When the tool is changed, firstly, the main shaft of the automatic tool changing grinder reaches the position right above the tool bar 310 under the accurate control of the intelligent control system, then the main shaft moves downwards to firmly clamp the tool bar 310, and then the main shaft moves upwards with the tool bar 310. Because of the existence of the cutter lifting gap 800, the upper end surface of the positioning shaft 330 does not touch the follow-up sealing gasket 410 when the cutter moves upwards. Since the cap 200 is fixed to the grinding cup 100 when the cutter moves, the pin 510 in the positioning hole 210 is also fixed. As the cutter bar 310 moves upward, the cutter-hanging groove 521 moves upward and separates from the pin 510, and the pin 510 moves upward while driving the spiral groove 523 to rotate the positioning shaft 330. When the vertical slot 522 rotated onto the positioning shaft 330 aligns with the pin 510, the knife bar 310 immediately changes direction from upward to downward movement, the vertical slot 522 moves downward along the pin 510 until the vertical slot 522 disengages from the pin 510, at which point the thin knife bar 310 enters the positioning hole 210, and the positioning shaft 330 is no longer constrained by the pin 510. At this point the spindle rotates at a high speed with the knife bar 310 and the knife bar 310 rotates at a high speed with the knife blade 320, the knife blade 320 moving downward while rotating until the material in the grinding cup 100 is thoroughly ground. The spindle then releases the tool bar 310, leaving the tool in the grinding cup 100, and then the spindle reaches directly above the next grinding cup 100 under the precise control of the intelligent control system, repeating the same actions until all work has been done. The cutter bar 310 is always positioned in the gland hole 421 during grinding, but the gland hole 421 is larger than the diameter of the cutter bar 310, and friction can not occur between the two. Below the gland 420 is a follower seal 410, and the center of the follower seal 410 is a seal hole 411. The seal hole 411 and the shank 310 have a small clearance so as not to allow the grinding media to fly out of the clearance. In addition, when the gap is small, surface tension is generated when the cutter bar 310 rotates at high speed in the sealing hole 411, and the tension forms air lock in the small gap, so that no grinding medium splashes out. Because of the annular follower gap 600 around the follower seal 410, the follower seal 410 will move with the knife bar 310 within the follower gap 600 and remain highly concentric with the knife bar 310 at all times. The seal hole 411 is not ground by the cutter bar 310, and the follower packing 410 is made of a wear-resistant material, so that the seal is ensured. The gland 420 presses the follower seal 410 against the follower seal 410 to move up and down, but the gland 420 cannot press the follower seal 410 to be dead, so that a certain floating gap 700 is ensured, and the gap is small, so long as the follower seal 410 can move along with the cutter bar 310. In addition, the upper and lower planes of the follow-up gasket 410 and the lower end surface of the gland 420 and the upper end surface of the positioning hole 210 form a labyrinth seal. This seal changes the direction of the flow of the grinding media and creates a large flow resistance so that the grinding media does not fly out along the follower gap 600.
The invention has the advantages that: the cutter is fixed on the cup cover 200 of the grinding cup 100, the cup cover 200 is directly used as a cutter magazine, the cutter magazine is not needed to be additionally arranged, the space is saved, and meanwhile, automatic cutter changing can be realized. The sealing cap reliably seals the grinding media within the grinding cup 100 during grinding without any leakage.
Example 1
Referring to fig. 1, a self-sealing cup-lid tool magazine according to an embodiment of the present invention includes a cup lid 200, a grinding tool 300, a follow-up seal 410 and a gland 420. The center of the cup cover 200 is sequentially provided with a positioning hole 210, a first mounting hole 220 and a second mounting hole 230, and the aperture of the positioning hole 210, the aperture of the first mounting hole 220 and the aperture of the second mounting hole 230 are sequentially increased. The follower packing 410 is movably installed in the first installation hole 220, and a sealing hole 411 is opened at the center of the follower packing 410. The gland 420 is installed in the second installation hole 230, the gland 420 is used to apply a pressing force to the follower packing 410 toward the positioning hole 210, and a gland hole 421 is opened in the center of the gland 420. The grinding blade 300 includes a cutter bar 310 and a blade 320, the blade 320 is connected to one end of the cutter bar 310, and the end sidewall of the cutter bar 310 near the blade 320 protrudes outward to form a positioning shaft 330 having an outer diameter larger than the cutter bar 310. One end of the cutter bar 310 far away from the blade 320 can sequentially pass through the positioning hole 210, the sealing hole 411 and the gland hole 421, wherein the aperture of the gland hole 421 is larger than the outer diameter of the cutter bar 310, and the aperture of the sealing hole 411 is matched with the outer diameter of the cutter bar 310. The aperture of the positioning hole 210 is matched with the outer diameter of the positioning shaft 330, a pin 510 is arranged on the hole wall of the positioning hole 210, and a clamping groove 520 is arranged on the positioning shaft 330 corresponding to the pin 510. The pin 510 can be clamped in the clamping groove 520, so that the positioning shaft 330 can be hung in the positioning hole 210.
Because the outer diameter of the positioning shaft 330 is larger than the outer diameter of the cutter bar 310, when the positioning shaft 330 is separated from the positioning hole 210 to move the grinding blade 300 towards the grinding cup 100 and rotate to grind under the action of external force, a large gap exists between the cutter bar 310 and the positioning hole 210, so that the grinding medium can splash outwards. By providing the follower seal 410, the bore diameter of the seal bore 411 thereon is adapted to the outer diameter of the tool shank 310, specifically meaning that the clearance between the seal bore 411 and the tool shank 310 is small. Only a small gap ensures that the grinding media does not fly out of the gap during grinding. In addition, when the gap is small, surface tension is generated when the cutter bar 310 rotates at high speed in the sealing hole 411, and the tension forms air lock in the small gap, so that no grinding medium splashes out. The pressing cover 420 is used for pressing the follow-up gasket 410 to ensure that the follow-up gasket 410 can perform a sealing function. The aperture of the gland hole 421 is larger than the outer diameter of the tool bar 310, so the gland hole 421 is not worn out by the rotation of the tool bar 310.
The positioning shaft 330 can be hung in the positioning hole 210 through the pin 510 and the clamping groove 520, so that the cutter bar 310 can be hung on the cup cover 200. This can facilitate storage of the polishing blade 300 when not in use. In this embodiment, the cup cover 200 can be directly used as a tool magazine for storing the grinding tools 300, and no additional tool magazine is needed, so that space and cost are saved. By providing the follower packing 410 and the gland 420, the grinding media can be effectively prevented from splashing along the gap between the cutter bar 310 and the positioning hole 210. Thereby realizing a reliable sealing of the grinding media in the grinding cup 100 during the grinding process, avoiding the phenomenon of leakage of the grinding media.
Referring to fig. 2, as an embodiment, an annular follow-up gap 600 exists between the periphery of the follow-up seal 410 and the wall of the first mounting hole 220. By arranging the follow-up gap 600, the follow-up sealing gasket 410 can move in the follow-up gap 600 along with the rotation of the cutter bar 310 and always keep the height concentricity with the cutter bar 310, so that the sealing hole 411 in the center of the follow-up sealing gasket 410 is prevented from being increased due to abrasion, and the tightness of the cup cover 200 during grinding is effectively ensured. In addition, the follow-up sealing gasket 410 can be made of wear-resistant materials, so that sealing performance is ensured.
Referring to fig. 2, further, a floating gap 700 exists between the surface of the follower seal 410 opposite the gland 420 and the gland 420. The pressing cover 420 is for pressing the follow-up gasket 410 to prevent the follow-up gasket 410 from moving up and down. But the gland 420 cannot compress the follower seal 410. By providing the floating gap 700, the follower seal 410 can slightly move within the floating gap 700 with the rotation of the cutter bar 310, so that the follower seal 410 can maintain a state of following the cutter bar 310. Thereby avoiding the abrasion of the follow-up sealing gasket 410 by the cutter bar 310 and effectively ensuring the tightness of the cup cover 200 during grinding.
Referring to fig. 2, in one embodiment, the hole wall of the gland hole 421 protrudes toward the side of the follower packing 410 to form an annular step 422, and the annular step 422 is fittingly mounted in the first mounting hole 220. Through the annular step 422, a pressing force is easily applied to the follow-up sealing gasket 410, and meanwhile, the thickness of the follow-up sealing gasket 410 can be reduced, and the difficulty of splashing of grinding media is increased.
The cap 200 of the present embodiment may be used to cover the grinding cup 100. The cup cover 200 can be covered on the grinding cup 100 in various ways. In one embodiment, the grind cup 100 and the cap 200 are threadably connected. It will be appreciated that the grinding cup 100 and the cup cover 200 may be threaded such that the inner wall of the rim of the grinding cup 100 is provided with an internal thread, the cup cover 200 is provided with an annular rib matched with the inner wall of the rim of the cup, and the outer side wall of the annular rib is provided with an external thread matched with the internal thread. Alternatively, the grinding cup 100 and the cup cover 200 may be connected by screw, the outer wall of the cup mouth of the grinding cup 100 is provided with external screw thread, the cup cover 200 is provided with an annular surrounding edge matched with the outer wall of the cup mouth, and the inner side wall of the annular surrounding edge is provided with internal screw thread matched with the external screw thread. Of course, the grinding cup 100 and the cup cover 200 may be connected by a snap structure or the like.
The blade 320 may be attached to the tool bar 310 in a variety of ways. The blade 320 may be welded directly to the cutter bar 310 at a predetermined location. Alternatively, the blade 320 may be fixed to the predetermined position of the cutter bar 310 using a fastener such as a screw. Referring to fig. 3, in one embodiment, the blade 320 includes a primary blade 321 and a secondary blade 322, the primary blade 321 and the secondary blade 322 are disposed at intervals along the axial direction of the cutter bar 310, and projections of the primary blade 321 and the secondary blade 322 on a plane perpendicular to the axial direction of the cutter bar 310 are offset from each other. In other words, as shown in fig. 3, the main blade 321 and the sub blade 322 are mounted on the cutter bar 310 in a vertically offset manner in a left-right distribution. The number of primary blades 321 may be more than one. The number of the sub blades 322 may be more than one. The main blade 321 and the auxiliary blade 322 which are installed in a vertically staggered mode can enable the grinding efficiency to be higher, and the grinding effect to be better.
The aperture of the positioning hole 210 is matched with the outer diameter of the positioning shaft 330, specifically, the positioning hole 210 and the positioning shaft 330 meet the tolerance matching requirement of the shaft hole, so that the positioning shaft 330 can be well erected in the positioning hole 210 when the cutter bar 310 is hung on the cup cover 200. Referring to fig. 1 and 3, in one embodiment, the clamping groove 520 includes a cutter hanging groove 521, a spiral groove 523 and a vertical groove 522, wherein the cutter hanging groove 521 and the vertical groove 522 are both opened on an outer sidewall of the positioning shaft 330 along a direction parallel to an axis of the cutter bar 310, one end of the cutter hanging groove 521, which is far away from the blade 320, is closed, the other end of the cutter hanging groove 521 is communicated with one end of the spiral groove 523, the other end of the spiral groove 523 is communicated with one end of the vertical groove 522, and the other end of the vertical groove 522 penetrates an end face of the positioning shaft 330. When hanging the knife, firstly, the end of the knife bar 310 far away from the knife blade 320 is inserted into the positioning hole 210, and the aperture of the positioning hole 210 is matched with the outer diameter of the positioning shaft 330 because the pin 510 protrudes out of the hole wall of the positioning hole 210. Thus, during continued insertion of the tool bar 310, the pin 510 may abut the end surface of the positioning shaft 330 such that the tool bar 310 cannot continue to advance. At this time, the cutter bar 310 is rotated to align the vertical slot 522 with the pin 510, so as to continuously push the cutter bar 310 forward. After the pin 510 enters the vertical groove 522 for a certain distance, the cutter bar 310 is rotated to enable the pin 510 to just fall into the cutter hanging groove 521, at this time, the cutter bar 310 is firmly hung by the pin 510, and the cutter bar 310 can be reliably erected in the positioning hole 210 without falling off by means of self weight, so that the grinding cutter 300 can be reliably hung on the cup cover 200.
When retracting the tool, i.e. when the positioning shaft 330 needs to be separated from the positioning hole 210, the above steps need only be reversed. Specifically, moving knife bar 310 upward causes pin 510 to move along hanging knife channel 521 toward spiral channel 523, pin 510 moves through spiral channel 523 toward vertical channel 522, and after pin 510 enters vertical channel 522, knife bar 310 is moved downward such that pin 510 is completely disengaged from vertical channel 522. So that the positioning shaft 330 is also removed from the positioning hole 210 and the grinding blade 300 is no longer restrained by the pin 510. Whereby the blade 320 is capable of grinding the substance within the grinding cup 100.
It will be appreciated that the number of pins 510 may be one and the corresponding number of slots 520. The number of pins 510 may be two, and two pins 510 are symmetrically disposed on the wall of the positioning hole 210. The number of the corresponding clamping grooves 520 is also two, and the two clamping grooves 520 are respectively arranged on the positioning shaft 330 corresponding to the two pins 510.
Referring to fig. 3, in one embodiment, the vertical groove 522 is provided with a guide slope 524 near the end surface of the positioning shaft 330, and the guide slope 524 is contracted toward the vertical groove 522. By guiding ramp 524, pin 510 can enter vertical slot 522 more smoothly during blade hanging.
Referring to fig. 1, as an embodiment, when the grinding cutter 300 is hung on the cup cover 200, a cutter gap 800 exists between the end surface of the positioning shaft 330 far from the blade 320 and the follow-up sealing pad 410, and the distance of the cutter gap 800 is slightly greater than the length of the cutter hanging groove 521 along the axial direction of the cutter bar 310. By means of the cutter-lifting gap 800, it is ensured that the positioning shaft 330 does not touch the follow-up seal 410 during the process of moving the cutter bar 310 upwards to move the pin 510 from the cutter-hanging groove 521 to the spiral groove 523 when retracting the cutter. Thereby effectively ensuring the tightness of the cup cover 200.

Referring to fig. 1, a self-sealing cup-lid tool magazine according to an embodiment of the present invention includes a cup lid 200, a grinding blade 300, a sealing structure 400, and a hanging blade structure 500. The cup cover 200 is provided with a positioning hole 210. The grinding blade 300 includes a cutter bar 310 and a blade 320, the blade 320 is connected to one end of the cutter bar 310, and the end sidewall of the cutter bar 310 near the blade 320 protrudes outward to form a positioning shaft 330 having an outer diameter larger than the cutter bar 310. The end of the cutter bar 310 remote from the blade 320 is capable of passing through the positioning hole 210, and the sealing structure 400 is disposed on the cap 200 for sealing the gap between the cutter bar 310 and the positioning hole 210. The aperture of the positioning hole 210 is adapted to the outer diameter of the positioning shaft 330, and the cutter hanging structure 500 is disposed between the positioning shaft 330 and the positioning hole 210, so that the cutter bar 310 can be hung on the cup cover 200.
The cutter bar 310 can be hung on the cup cover 200 by the cutter hanging structure 500, so that the grinding cutter 300 which is not in use can be stored conveniently. And furthermore, the cup cover 200 can be directly used as a tool magazine for storing the grinding tools 300, and the tool magazine is not required to be additionally arranged, so that the space is saved, and the cost is saved. By providing the sealing structure 400, the grinding media can be effectively prevented from splashing along the gap between the cutter bar 310 and the positioning hole 210. Thereby realizing a reliable sealing of the grinding media in the grinding cup 100 during the grinding process, avoiding the phenomenon of leakage of the grinding media.
The sealing structure 400 may have various structural forms. Referring to fig. 1 and 2, as one implementation, the seal structure 400 includes a follower seal 410 and a gland 420. The cup cover 200 is further provided with a first mounting hole 220 and a second mounting hole 230, the positioning hole 210, the first mounting hole 220 and the second mounting hole 230 are sequentially distributed on the cup cover 200, and the aperture of the positioning hole 210, the aperture of the first mounting hole 220 and the aperture of the second mounting hole 230 are sequentially increased. The follower packing 410 is movably installed in the first installation hole 220, and a sealing hole 411 is opened at the center of the follower packing 410. The gland 420 is installed in the second installation hole 230, the gland 420 is used to apply a pressing force to the follower packing 410 toward the positioning hole 210, and a gland hole 421 is opened in the center of the gland 420. One end of the cutter bar 310 far away from the blade 320 can sequentially pass through the positioning hole 210, the sealing hole 411 and the gland hole 421, wherein the aperture of the gland hole 421 is larger than the outer diameter of the cutter bar 310, and the aperture of the sealing hole 411 is matched with the outer diameter of the cutter bar 310.
It will be appreciated that, since the outer diameter of the positioning shaft 330 is larger than the outer diameter of the tool bar 310, when the positioning shaft 330 is disengaged from the positioning hole 210 to move the grinding blade 300 toward the grinding cup 100 and rotate under the external force to grind, a large gap exists between the tool bar 310 and the positioning hole 210, so that the grinding medium can splash outwards. By providing a follower seal 410, the bore diameter of the seal bore 411 thereon is adapted to the outer diameter of the tool shank 310, meaning that the clearance between the seal bore 411 and the tool shank 310 is small. Only a small gap ensures that the grinding media does not fly out of the gap during grinding. In addition, when the gap is small, surface tension is generated when the cutter bar 310 rotates at high speed in the sealing hole 411, and the tension forms air lock in the small gap, so that no grinding medium splashes out. The pressing cover 420 is mainly used for applying pressure to the follow-up sealing gasket 410, so that the follow-up sealing gasket 410 is prevented from being separated from the cup cover 200, and the sealing effectiveness is ensured. The aperture of the gland hole 421 is larger than the outer diameter of the tool bar 310, so the gland hole 421 is not worn out by the rotation of the tool bar 310. By providing the follower packing 410 and the gland 420, the grinding media can be effectively prevented from splashing along the gap between the cutter bar 310 and the positioning hole 210. Thereby realizing a reliable sealing of the grinding media in the grinding cup 100 during the grinding process, avoiding the phenomenon of leakage of the grinding media.
Referring to fig. 2, in one embodiment, an annular follower gap 600 exists between the periphery of the follower seal 410 and the bore wall of the first mounting bore 220. By arranging the follow-up gap 600, the follow-up sealing gasket 410 can move in the follow-up gap 600 along with the rotation of the cutter bar 310 and always keep the height concentricity with the cutter bar 310, so that the sealing hole 411 in the center of the follow-up sealing gasket 410 is prevented from being increased due to abrasion, and the tightness of the cup cover 200 during grinding is effectively ensured. In addition, the follow-up sealing gasket 410 can be made of wear-resistant materials, so that sealing performance is ensured.
Referring to fig. 2, further, a floating gap 700 exists between the surface of the follower seal 410 opposite the gland 420 and the gland 420. The pressing cover 420 is for pressing the follow-up gasket 410 to prevent the follow-up gasket 410 from moving up and down. But the gland 420 cannot compress the follower seal 410. By providing the floating gap 700, the follower seal 410 can slightly move within the floating gap 700 with the rotation of the cutter bar 310, so that the follower seal 410 can maintain a state of following the cutter bar 310. Thereby avoiding the abrasion of the follow-up sealing gasket 410 by the cutter bar 310 and effectively ensuring the tightness of the cup cover 200 during grinding.
Referring to fig. 2, in one embodiment, the hole wall of the gland hole 421 protrudes toward the side of the follower packing 410 to form an annular step 422, and the annular step 422 is fittingly mounted in the first mounting hole 220. Through the annular step 422, a pressing force is easily applied to the follow-up sealing gasket 410, and meanwhile, the thickness of the follow-up sealing gasket 410 can be reduced, and the difficulty of splashing of grinding media is increased.
In other embodiments, the seal 400 may also include an annular curtain of sealant that may be disposed at the locating hole 210, with a plurality of curtain teeth extending toward the center of the locating hole 210, the plurality of curtain teeth forming a hole slightly smaller than the outer diameter of the knife bar 310. When the positioning shaft 330 is separated from the positioning hole 210 and the grinding blade 300 moves in the direction of the grinding cup 100 and rotates to grind under the action of external force, since there is substantially no gap between the plurality of seal curtain teeth and the cutter bar 310, the grinding medium can be effectively prevented from splashing outward. Alternatively, the sealing structure 400 may further include a sealing rubber ring. The sealing rubber ring is made of softer elastic materials. The sealing rubber ring is fixed at the positioning hole 210 of the cup cover 200, and a hole matched with the outer diameter of the cutter bar 310 is formed in the center of the sealing rubber ring. When the positioning shaft 330 is separated from the positioning hole 210 and the grinding blade 300 moves in the direction of the grinding cup 100 and rotates to grind under the action of external force, the sealing rubber ring and the cutter bar 310 have no gap basically, so that the grinding medium can be effectively prevented from splashing outwards.
The cap 200 of the present embodiment may be used to cover the grinding cup 100. The cup cover 200 can be covered on the grinding cup 100 in various ways.

Of course, the grinding cup 100 and the cup cover 200 may be connected by a snap structure or the like.
The blade 320 may be attached to the tool bar 310 in a variety of ways. The blade 320 may be welded directly to the cutter bar 310 at a predetermined location. Alternatively, the blade 320 may be fixed to the predetermined position of the cutter bar 310 using a fastener such as a screw. Referring to fig. 3, in one embodiment, the blade 320 includes a primary blade 321 and a secondary blade 322, the primary blade 321 and the secondary blade 322 are disposed at intervals along the axial direction of the cutter bar 310, and projections of the primary blade 321 and the secondary blade 322 on a plane perpendicular to the axial direction of the cutter bar 310 are offset from each other. In other words, as shown in fig. 3, the main blade 321 and the sub blade 322 are mounted on the cutter bar 310 in a vertically offset manner in a left-right distribution. The number of primary blades 321 may be more than one. The number of the sub blades 322 may be more than one. The main blade 321 and the auxiliary blade 322 which are installed in a vertically staggered mode can enable the grinding efficiency to be higher, and the grinding effect to be better.
The hanging knife structure 500 can also have various structural forms. Referring to fig. 1 to 3, as an embodiment, the hanging knife structure 500 includes a pin 510 and a slot 520, the pin 510 is disposed on a wall of the positioning hole 210, and the slot 520 is disposed on an outer wall of the positioning shaft 330 corresponding to the pin 510. The pin 510 can be clamped in the clamping groove 520, so that the positioning shaft 330 can be hung in the positioning hole 210. The positioning shaft 330 can be hung in the positioning hole 210 through the pin 510 and the clamping groove 520, so that the cutter bar 310 can be hung on the cup cover 200. Therefore, the grinding knife 300 not in the use state can be conveniently stored, the cup cover 200 can be directly used as a knife magazine for storing the grinding knife 300, the knife magazine is not required to be additionally arranged, the space is saved, and the cost is saved.
Referring to fig. 3, in one embodiment, the clamping groove 520 includes a cutter hanging groove 521, a spiral groove 523 and a vertical groove 522, wherein the cutter hanging groove 521 and the vertical groove 522 are both opened on an outer sidewall of the positioning shaft 330 in a direction parallel to an axis of the cutter bar 310, and one end of the cutter hanging groove 521, which is far away from the blade 320, is closed, the other end of the cutter hanging groove 521 is communicated with one end of the spiral groove 523, the other end of the spiral groove 523 is communicated with one end of the vertical groove 522, and the other end of the vertical groove 522 penetrates an end face of the positioning shaft 330. When hanging the knife, firstly, the end of the knife bar 310 far away from the knife blade 320 is inserted into the positioning hole 210, and the aperture of the positioning hole 210 is matched with the outer diameter of the positioning shaft 330 because the pin 510 protrudes out of the hole wall of the positioning hole 210. Thus, during continued insertion of the tool bar 310, the pin 510 may abut the end surface of the positioning shaft 330 such that the tool bar 310 cannot continue to advance. At this time, the cutter bar 310 is rotated to align the vertical slot 522 with the pin 510, so as to continuously push the cutter bar 310 forward. After the pin 510 enters the vertical groove 522 for a certain distance, the cutter bar 310 is rotated to enable the pin 510 to just fall into the cutter hanging groove 521, at this time, the cutter bar 310 is firmly hung by the pin 510, and the cutter bar 310 can be reliably erected in the positioning hole 210 without falling off by means of self weight, so that the grinding cutter 300 can be reliably hung on the cup cover 200.
When retracting the tool, i.e. when the positioning shaft 330 needs to be separated from the positioning hole 210, the above steps need only be reversed. Specifically, moving knife bar 310 upward causes pin 510 to move along hanging knife channel 521 toward spiral channel 523, pin 510 moves through spiral channel 523 toward vertical channel 522, and after pin 510 enters vertical channel 522, knife bar 310 is moved downward such that pin 510 is completely disengaged from vertical channel 522. So that the positioning shaft 330 is also removed from the positioning hole 210 and the grinding blade 300 is no longer restrained by the pin 510. Whereby the blade 320 is capable of grinding the substance within the grinding cup 100.
It will be appreciated that the number of pins 510 may be one and the corresponding number of slots 520. The number of pins 510 may be two, and two pins 510 are symmetrically disposed on the wall of the positioning hole 210. The number of the corresponding clamping grooves 520 is also two, and the two clamping grooves 520 are respectively arranged on the positioning shaft 330 corresponding to the two pins 510.
Referring to fig. 3, in one embodiment, the vertical groove 522 is provided with a guide slope 524 near the end surface of the positioning shaft 330, and the guide slope 524 is contracted toward the vertical groove 522. By guiding ramp 524, pin 510 can enter vertical slot 522 more smoothly during blade hanging.
Referring to fig. 1, further, when the grinding cutter 300 is hung on the cup cover 200, a cutter-lifting gap 800 exists between the end surface of the positioning shaft 330 far from the blade 320 and the follow-up sealing gasket 410, and the distance of the cutter-lifting gap 800 is slightly greater than the length of the cutter-hanging groove 521 along the axial direction of the cutter bar 310. By means of the cutter-lifting gap 800, it is ensured that the positioning shaft 330 does not touch the follow-up seal 410 during the process of moving the cutter bar 310 upwards to move the pin 510 from the cutter-hanging groove 521 to the spiral groove 523 when retracting the cutter. Thereby effectively ensuring the tightness of the cup cover 200.
In other embodiments, the hanging knife structure 500 may also include an externally threaded section disposed on the outer wall of the locating shaft 330 and an internally threaded section disposed on the wall of the locating hole 210. The positioning shaft 330 is hung in the positioning hole 210 through the cooperation of the external thread and the internal thread, so that the grinding cutter 300 can be hung on the cup cover 200. It will be appreciated that the hanging knife structure 500 can take other forms, as long as the hanging of the positioning shaft 330 in the positioning hole 210 is achieved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
