Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments are used to further describe the full-automatic grinding apparatus with the clamping guide sleeve according to the present invention in detail 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, 3 and 4, a plurality of positioning counter bores 610 are formed on a positioning plate 600 of the full-automatic grinding apparatus 10 with the clamping guide sleeve, a pillar hole 710 is formed at the edge of the positioning counter bore 610, the grinding cup 100 is placed into the positioning counter bore 610, and the pillar 720 at the bottom of the grinding cup 100 is rotated to fall into the pillar hole 710. Prior to placing the grind cup 100 onto the locating plate 600, the cutter bar 310 is first manually installed into the cap locating aperture 210 and the cap 200 is then screwed onto the grind cup 100. When the cutter bar 310 is installed, the end of the guide conical surface 311 of the cutter bar 310 is inserted into the cup cover positioning hole 210 to push the cutter bar 310 to advance. When the stepped end surface 341 of the cutter bar positioning shaft 340 resists against the cutter hanging bump 510 and cannot advance, the cutter bar 310 is rotated to align the vertical groove 522 with the cutter hanging bump 510, so that the cutter bar positioning shaft 340 can be continuously pushed to advance. The guiding inclined plane 524 makes it easier for the hanging knife protruding point 510 to enter the vertical groove 522, and when the hanging knife protruding point 510 enters the vertical groove 522 for a certain distance, the hanging knife 310 rotates to enable the hanging knife protruding point 510 to just fall into the hanging knife groove 521, and at the moment, the hanging knife protruding point 510 can firmly hang the hanging knife 310, and the hanging knife 310 can reliably stand upright in the cup cover positioning hole 210 by means of dead weight and cannot fall. After all the grinding cups 100 are put, when the electric spindle 400 and the pneumatic pressing mechanism 800 start to work, the electric spindle 400 and the pneumatic pressing mechanism 800 move above the grinding cups 100, the pneumatic pressing mechanism 800 moves downwards to press the cup cover 200 tightly, and then the electric spindle 400 moves downwards to approach the cutter bar 310. Firstly, the guiding conical surface 421 at the lower end of the clamping sleeve 420 and the guiding conical surface 311 at the top end of the cutter bar 310 are firstly touched together, and the cutter bar 310 can easily enter the clamping hole 410 of the electric spindle 400 under the combined action of the guiding conical surface 421 and the guiding conical surface 311. When the cutter bar 310 enters the clamping hole 410 of the motorized spindle 400 for a certain distance, the clamping hole 410 firmly clamps the cutter bar 310. Then, the electric spindle 400 moves upward with the cutter bar 310 interposed therebetween, and when the cutter bar 310 moves upward, the cutter protrusion 510 is disengaged from the cutter groove 521, and the cutter protrusion 510 enters the spiral groove 523. During the upward movement of the cutter bar 310, the cutter bar 310 rotates while moving upward due to the hooking protrusion 510 and the spiral groove 523. As the cutter bar 310 moves upward, the vertical slot 522 gets closer to the cutter protrusion 510, and when the cutter protrusion 510 enters the vertical slot 522, the motorized spindle 400 changes the moving direction in time, from upward movement to downward movement, until the cutter protrusion 510 and the vertical slot 522 are completely separated. Meanwhile, the cutter bar positioning shaft 340 and the cup cover positioning hole 210 are also separated, and the cutter bar 310 is not limited by the cutter hanging convex point 510 and the cup cover positioning hole 210 at the moment. Motorized spindle 400 drives knife bar 310 to rotate at a high speed, knife bar 310 moves downward with motorized spindle 400 while rotating until the cup bottom. The main blade 321 and the auxiliary blade 322 at the lower part of the cutter bar 310 are separated by a spacer 330, and the main blade 321 and the auxiliary blade 322 are arranged in a left-right distribution and staggered way. This mounting structure ensures the highest grinding efficiency and the best grinding effect. When all the materials in the grinding cup 100 are thoroughly ground, the clamping hole 410 releases the cutter bar 310, and the electric spindle 400 moves upwards to leave the cutter in the grinding cup 100. The pneumatic pressing mechanism 800 then also moves upward away from the cover of the grinding cup 100, and then the motorized spindle 400 and the pneumatic pressing mechanism 800 move directly over the next grinding cup 100, starting a new grinding operation, and the operation flow is exactly the same as the previous one, and the cycle is repeated until all grinding tasks are completed.
The invention has the advantages that: the automatic grinding apparatus 10 with the clamping guide sleeve can easily enter the clamping hole 410 of the motorized spindle 400 under the combined action of the guiding conical surface 311 of the cutter bar 310 and the guiding conical surface 421 of the clamping guide sleeve 420 no matter whether the cutter bar 310 is vertical to the cup cover 200 or not. The motorized spindle 400 can reliably clamp each cutter bar 310 firmly, and the clamping reliability is greatly improved. In addition, each grinding cup 100 is internally provided with an independent grinding knife 300, so that the risk of cross contamination is avoided, and the grinding cup 100 and the grinding knife 300 are simple in structure and convenient to clean. Because the bottom of the grinding cup 100 is pore-free, no bottom sealing is required, and no leakage problem exists. In particular, the grinding blade 300 can move up and down in the cup while rotating at a high speed, and can grind layer by layer, so that the grinding blade can grind very fine and smooth materials with low water content as well as frozen materials. Because the grinding knife 300 can move up and down in the cup, materials can be rolled circularly without the help of moisture, and particularly, the grinding effect of vertically staggered mounting of the main blade and the auxiliary blade is greatly improved, the trouble that the grinding cannot be carried out due to low moisture in fruit and vegetable grinding is thoroughly solved, and the grinding is really free from worry.

The cup cover 200 is provided with a cup cover positioning hole 210, and one end of the cutter bar 310, which is far away from the blade 320, passes through the cup cover positioning hole 210 and is connected with the electric spindle 400. The electric spindle 400 is used for driving the cutter bar 310 to rotate, the end of the electric spindle 400 is provided with a clamping hole 410, and the clamping hole 410 is used for clamping one end of the cutter bar 310 away from the blade 320. The end of the motorized spindle 400 is further sleeved with a clamping guide sleeve 420, the clamping guide sleeve 420 is provided with a guide hole communicated with the clamping hole 410, and the aperture of the guide hole is tapered along the direction that the cutter bar 310 is inserted into the clamping hole 410, so as to form a guide conical surface 421 for guiding the cutter bar 310 into the clamping hole 410. The cutter bar 310 is provided with a cutter bar positioning shaft 340 near the outer side wall of the blade 320, an annular step end surface 341 is formed between the cutter bar positioning shaft 340 and the outer side wall of the cutter bar 310, and the cutter bar positioning shaft 340 is matched with the cup cover positioning hole 210. The hole wall of the cup cover positioning hole 210 is provided with a hanging knife salient point 510, and the cutter bar positioning shaft 340 is provided with a hanging knife clamping groove 520 corresponding to the hanging knife salient point 510. The hanging knife protruding point 510 can be clamped in the hanging knife clamping groove 520, so that the knife bar 310 can be hung on the cup cover 200.
The electric spindle 400 drives the cutter bar 310 to rotate, so that the blade 320 is driven to rotate, and the grinding of substances in the grinding cup 100 is realized. By arranging the clamping guide sleeve 420, the clamping guide sleeve 420 is provided with the guide conical surface 421 for guiding the cutter bar 310 to enter the clamping hole 410, so that a good guiding effect is achieved on the cutter bar 310 entering the clamping hole 410, the cutter bar 310 can enter the clamping hole 410 relatively easily to be clamped, and the assembly efficiency of the grinding cutter 300 is improved. The cutter bar 310 can be hung on the cup cover 200 through the cutter hanging convex points 510 and the cutter hanging clamping grooves 520, 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.
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 sleeved outside the cutter bar 310, and then fixed at a predetermined position of the cutter bar 310 by a fastener such as a screw. Referring to fig. 1, 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. 2, 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.
Further, the main blade 321 and the auxiliary blade 322 are both sleeved outside the cutter bar 310 and can be fixed relative to the cutter bar 310. The grinding blade 300 further includes a spacer 330, wherein the spacer 330 is sleeved outside the cutter bar 310 and between the main blade 321 and the auxiliary blade 322. By providing the spacer 330, the main blade 321 and the sub blade 322 can be well supported, and the two end surfaces of the spacer 330 can be used as the mounting surfaces of the main blade 321 and the sub blade 322, so that the fastening and the mounting of the main blade 321 and the sub blade 322 are facilitated.
Referring to fig. 1 and 2, in one embodiment, an end of the tool bar 310 remote from the insert 320 is tapered in a direction in which the tool bar 310 is inserted into the clamping hole 410, such that the end of the tool bar 310 remote from the insert 320 forms a guide tapered surface 311. The guiding conical surface 311 is used for being matched with the guiding conical surface 421, when the electric spindle 400 moves downwards to approach the tool bar 310, the guiding conical surface 421 at the lower end of the clamping guide sleeve 420 is firstly contacted with the guiding conical surface 311 at the top end of the tool bar 310, and under the combined action of the guiding conical surface 421 and the guiding conical surface 311, the tool bar 310 can easily enter the clamping hole 410 of the electric spindle 400.
Referring to fig. 1 and 2, in one embodiment, the cutter clamping groove 520 includes a cutter clamping groove 521, a spiral groove 523 and a vertical groove 522, where the cutter clamping groove 521 and the vertical groove 522 are both opened on an outer sidewall of the cutter bar positioning shaft 340 along a direction parallel to an axis of the cutter bar 310, and one end of the cutter clamping groove 521, which is far away from the cutter blade 320, is closed, the other end of the cutter clamping 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 through the step end surface 341.
When hanging the cutter, firstly, the end of the cutter bar 310 far away from the blade 320 is inserted into the cup cover positioning hole 210, and as the cutter hanging convex point 510 protrudes out of the hole wall of the cup cover positioning hole 210, in the process of continuously inserting the cutter bar 310, the cutter hanging convex point 510 may abut against the step end surface 341, so that the cutter bar 310 cannot continuously advance. At this time, the cutter bar 310 is rotated to align the vertical slot 522 with the hanging cutter salient point 510, so as to continuously push the cutter bar 310 to advance. The hanging knife protruding point 510 enters the vertical groove 522 for a certain distance, and then the cutter bar 310 is rotated to enable the hanging knife protruding point 510 to just fall into the hanging knife groove 521, at this time, the cutter bar 310 can be firmly hung by the hanging knife protruding point 510, and the cutter bar 310 can be reliably erected in the cup cover positioning hole 210 by means of dead weight so as not to fall, thereby enabling the grinding knife 300 to be reliably hung on the cup cover 200.
When the cutter bar positioning shaft 340 needs to be separated from the cup cover positioning hole 210, the above steps only need to be reversed. Specifically, the hooking protrusion 510 is moved toward the vertical groove 522 along the hooking groove 521, and after passing through the spiral groove 523 and entering the vertical groove 522, the hooking protrusion 510 is moved toward the step end surface 341 along the vertical groove 522. When the hanging knife protruding point 510 is separated from the vertical groove 522, the knife bar positioning shaft 340 is separated from the cup cover positioning hole 210. And the spiral groove 523 is provided on the cutter bar positioning shaft 340 in a spiral direction of the cutter bar 310, and both ends of the spiral groove 523 are respectively communicated with the cutter hanging groove 521 and the vertical groove 522. The spiral slot 523 may serve as a guide slot for the withdrawal of the hanger bump 510 from the hanger slot 521 to the vertical slot 522. By providing the spiral groove 523, the cutter bar 310 can move upwards while rotating in the process that the cutter hanging salient point 510 moves along the spiral groove 523 by the cutter hanging groove 521 and reaches the vertical groove 522, so that the cutter bar positioning shaft 340 is convenient to separate from the cup cover positioning hole 210.
It is understood that the number of the hanging knife protruding points 510 may be one, and the number of the corresponding hanging knife clamping grooves 520 is also one. The number of the hanging knife protruding points 510 can be two, and the two hanging knife protruding points 510 are symmetrically arranged on the hole wall of the cup cover positioning hole 210. Correspondingly, the number of the cutter hanging clamping grooves 520 is two, and the two cutter hanging clamping grooves 520 are respectively arranged on the cutter bar positioning shaft 340 corresponding to the two cutter hanging convex points 510.
Referring to fig. 1 and 3, in one embodiment, the wall of the cap positioning hole 210 extends and protrudes toward a side surface of the cap 200. By extending the hole wall of the cap positioning hole 210 towards one side surface of the cap 200, the length of the matching section of the cap positioning hole 210 and the cutter bar positioning shaft 340 is longer, and the stability of hanging the cutter bar 310 on the cap 200 is improved.
Referring to fig. 2, in one embodiment, the vertical groove 522 is provided with a guide slope 524 near the step end surface 341, and the guide slope 524 is contracted in the direction from the step end surface 341 to the vertical groove 522. The hanging knife convex point 510 can smoothly enter the vertical groove 522 through the guiding inclined plane 524.
Referring to fig. 1 and 4, as an implementation manner, the full-automatic grinding apparatus 10 with the clamping guide sleeve further includes a grinding cup 100 and a positioning plate 600, and a plurality of positioning counter bores 610 are formed on the positioning plate 600. Each locating counterbore 610 may be used to mount a grinding cup 100. The cup cover 200 covers the cup mouth of the grinding cup 100. It will be appreciated that the diameter of the locating counterbore 610 is slightly larger than the outer diameter of the grinding cup 100 so that the grinding cup 100 can be easily placed into the locating counterbore 610. The bottom surface of the positioning counter bore 610 is also provided with a pin hole 710, and the bottom of the grinding cup 100 is provided with a pin 720 corresponding to the pin hole 710.
