[0002] At present, in the spinning workshop, in order to ensure the spinnability and quality of silk fabrics during the production process, silk fabrics are regularly cleaned. The cleaning process can remove monomers produced by high-temperature decomposition of polymers on the spinneret surface and coke from spraying release agents during cleaning. The tools used for cleaning include copper-aluminum plates, plastic or bamboo-wood scrapers. The scrapers require a special angle of the blade to achieve excellent cleaning effect. However, in the current chemical fiber production process, the chamfers (special angle of the blade) of copper-aluminum plates are still made with files and rely on manual grinding, which is time-consuming and labor-intensive, and the grinding effect is not ideal.

[0061] In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0062] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0063] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0064] like Figures 1 to 14As shown, this example provides a milling machine, which includes a milling mechanism and a displacement mechanism. The milling mechanism includes a milling cutter assembly 11 for milling, a locking assembly 12 at least configured to lock the milling cutter assembly 11 and drive the milling cutter assembly 11 to rotate, and a first driving assembly 13 configured to drive the locking assembly 12 to rotate. The milling cutter assembly 11 includes a milling cutter 111; the displacement mechanism is configured to drive the milling cutter assembly 11 to reach any position within a preset area; the preset area includes a milling area 100 and a milling cutter replacement area 200, the locking assembly 12 includes a locked state and an unlocked state, when the milling cutter assembly 11 is located in the milling area 100, the locking assembly 12 is in a locked state, and when the milling cutter assembly 11 is located in the milling cutter replacement area 200, the locking assembly 12 can switch from one of the locked state and the unlocked state to another state.
[0065] In this example, the milling cutter assembly 11 also includes a milling cutter fixing member 112, the milling cutter 111 is arranged on the milling cutter fixing member 112, the locking assembly 12 includes an elastic member 121, a locking member 122 connected to one end of the elastic member 121, and a locking mating portion 123 formed on the milling cutter fixing member 112, the locking member 122 can cooperate with the locking mating portion 123 to lock the milling cutter assembly 11; the elastic member 121 includes an extended state and a compressed state, when the locking assembly 12 is in a locked state, the elastic member 121 is in an extended state; when the locking assembly 12 is in an unlocked state, the elastic member 121 is in a compressed state.
[0066] Furthermore, the locking assembly 12 also includes a sleeve 124 having a accommodating cavity 1241 and a displacement channel 1242 that are interconnected, the other end of the elastic member 121 is connected to the sleeve 124, the locking member 122 passes through the displacement channel 1242 and can extend into the accommodating cavity 1241, and the milling cutter fixing member 112 can partially extend into the accommodating cavity 1241; wherein, the locking member 122 is slidably arranged in the displacement channel 1242 along its own axial direction, and the length of the locking member 122 extending into the accommodating cavity 1241 when the locking assembly 12 is in a locked state is less than the length of the locking member 122 extending into the accommodating cavity 1241 when the locking assembly 12 is in an unlocked state.
[0067] In some embodiments, the locking member 122 includes a locking shaft 1221 and at least one elastic buckle 1222 formed on the locking shaft 1221. The elastic buckle 1222 has multiple and surrounding arrangements, which is conducive to the engagement of the locking fitting portion 123. The locking fitting portion 123 is a card table that cooperates with the elastic buckle 1222. A guide inclined surface 12411 is formed on the inner wall of the accommodating cavity 1241. The outer end surface of the elastic buckle 1222 is abutted against the guide inclined surface 12411, and the guide inclined surface 12411 is inclined upward from the displacement channel 1242 to the direction of the accommodating cavity 1241; the elastic buckle 1222 includes an engaged state and a relaxed state. When the elastic buckle 1222 is in the engaged state, the elastic buckle 1222 is engaged with the card table, and the elastic member 121 is in an extended state; when the elastic buckle 1222 is in the relaxed state, the elastic buckle 1222 is away from the card table, and the elastic member 121 is in a compressed state. In this example, during the movement of the locking member 122, when the locking member 122 is moved toward a direction deeper into the accommodating cavity 1241, the elastic buckle 1222 moves along the guide inclined surface 12411 and opens outward, tending to change to a relaxed state, thereby achieving unlocking; when the locking member 122 is moved toward a direction of exiting the accommodating cavity 1241, the elastic buckle 1222 also moves along the guide inclined surface 12411 and contracts inward, tending to change to a clutched state, thereby achieving locking. In particular, while achieving the locking of the milling cutter assembly 11, since the elastic buckle 1222 is always restricted between the guide inclined surfaces 12411 or partially restricted in the displacement channel 1242 when it is clutched, the locking member 122 and the sleeve 124 are in an interference fit state, so that when the sleeve 124 rotates, the locking assembly 12 can also be driven to rotate.
[0068] Furthermore, one of the protrusion and the groove is formed on the outer end surface of the elastic buckle 1222, and the other of the protrusion and the groove is formed on the guide inclined surface 12411, and the protrusion is inserted in the groove and can be slid relative to the groove. Such a setting is conducive to more firmly combining the milling cutter assembly 11 with the locking assembly 12 through the elastic buckle 1222, especially through this setting, it can be ensured that the milling cutter assembly 11 can be better driven to rotate during the rotation of the locking assembly 12, and the stability and efficiency of the rotation of the milling cutter assembly 11 will determine the milling efficiency and quality.
[0069] In this example, the first drive assembly 13 includes a driving component and a transmission component, which are respectively connected to the driving component and the sleeve 124; the transmission component includes a driving gear connected to the driving component and a driven gear 1243 arranged on the sleeve 124, and the driving gear is meshed with the driven gear 1243.
[0070] In this example, a limiting groove 1121 is set on the milling cutter fixing member 112, and the milling machine also includes a spare milling cutter assembly 5 as a spare and two support members 3 for respectively carrying the milling cutter assembly 11 and the spare milling cutter assembly 5. The support member 3 is arranged in the milling cutter replacement area 200, and the spare milling cutter assembly 5 is arranged in the milling cutter replacement area 200. The limiting groove 1121 can cooperate with the support member 3 to limit the freedom of the milling cutter assembly 11 or the spare milling cutter assembly 5 in the direction of the rotation axis of the milling cutter 111. Furthermore, the number of support members 3 can be greater than 2, and the number of spare milling cutter assemblies 5 can be greater than 1, with 1 supporting member cooperating with the milling cutter assembly 11 for storing the worn or damaged milling cutter assembly 11, and the others all correspondingly cooperating with the spare milling cutter assembly one by one for placing the spare milling cutter assembly 5. Of course, if the milling cutter assembly is replaced once and the worn milling cutter assembly is removed, the controlled supporting member is used as a support limit for the spare milling cutter assembly, while the supporting member originally used to place the spare milling cutter assembly is left vacant to wait for a worn or damaged milling cutter assembly to be placed the next time the milling cutter assembly is replaced.
[0071] In this example, the milling machine also includes an unlocking component 4, and the locking component 12 and the unlocking component 4 are both arranged on the displacement mechanism; the unlocking component 4 includes a second driving component 41 for driving the locking member 122 to perform linear displacement, and the linear displacement direction of the locking member 122 is parallel to or coincides with the deformation direction of the elastic member 121.
[0072] The design of the above structure can realize the automatic replacement of the milling cutter assembly, and then the worn or damaged milling cutter can be replaced with a spare milling cutter, thereby ensuring the milling efficiency and milling quality.
[0073] As an optional embodiment, the milling cutter 111 includes a milling body and a plurality of diamond grinding discs arranged on the milling body; alternatively, the milling cutter 111 is made of diamond, and the diamond material can make the milling cutter more durable and increase its service life, while the milling quality and milling efficiency can be significantly improved.
[0074] In this example, the rotation plane of the milling cutter 111 extends in the up-down direction, and the rotation axis of the milling cutter 111 is perpendicular to the extension direction of the workpiece to be milled.
[0075] In this example, the displacement mechanism includes a first displacement component 21 for driving the milling mechanism to displace along a first direction, a second displacement component 22 for driving the first displacement component 21 to displace along a second direction, and a third displacement component 23 for driving the second displacement component 22 to displace along a third direction. The milling mechanism is arranged on the first displacement component 21, the first displacement component 21 is arranged on the second displacement component 22, and the second displacement component 22 is arranged on the third displacement component 23. Further, in some embodiments of the utility model, the first direction extends along the Z-axis direction of the Cartesian coordinate system (the Cartesian coordinate system is a general term for the rectangular coordinate system and the oblique coordinate system), the second direction extends along the X-axis direction of the Cartesian coordinate system, and the third direction extends along the Y-axis direction of the Cartesian coordinate system, that is, by positioning through the XYZ three points in a three-dimensional space, the design at any position within the preset area can be realized.
[0076] In this example, the milling machine also includes a limit fixing component 6 for limiting and fixing the part to be milled, and the limit fixing component 6 has a plurality of components arranged side by side. Further, in this example, since the milling cutter 111 is driven to move to achieve milling, when a plurality of limit fixing components 6 are arranged side by side, the milling cutter 111 can be controlled to sequentially mill multiple parts to be milled, thereby reducing the time for replacing the parts to be milled and greatly improving production efficiency. In the prior art, since the part to be milled is moved and the milling cutter rotates in situ to achieve milling, after milling one part to be milled, the machine needs to be stopped to replace another part to be milled, thus resulting in low milling efficiency. The utility model achieves milling by driving the milling cutter to move, and when multiple parts to be milled are arranged side by side at one time, they can be milled sequentially, thereby reducing the frequency of replacing the parts to be milled.
[0077] In this example, the milling machine also includes a control system 7, which is respectively communicated with the first drive component 13, the displacement mechanism, and the unlocking component 4, so that the start and stop of each component can be automatically controlled. In some embodiments, a preset control program can also be used, which can control the milling cutter to perform milling in sequence and in an orderly manner.
[0078] In this example, if Figures 1 to 2As shown, the milling machine of this example also includes a shell 8. The main function of the shell 8 is to support various components and provide a milling operation platform. For example, the shell 8 includes a hatch 81 for enclosing the milling cutter replacement area inside, a barrier 82 for separating the milling cutter replacement area from the milling area, and a discharge port 83 for discharging waste after milling. The hatch 81 is opened when needed. For example, when a damaged or worn milling cutter is replaced, the hatch 81 can be opened manually to take it out and place a new spare milling cutter assembly. It can be kept closed at other times; and the barrier 82 can be set to be openable and closable, or rotatable. When the inside is milling, it is closed to separate the milling cutter replacement area from the milling area to prevent debris or waste generated by milling from entering the milling cutter replacement area, and to make all waste materials be discharged from the discharge port 83 as much as possible.
[0079] Furthermore, if Figure 2 As shown, it shows that a spare milling cutter assembly and an empty support member 3 are provided in the milling cutter replacement area. The empty support member 3 is used for placing the milling cutter assembly that is worn or damaged to be replaced next time.
[0080] See also Figure 3 and Figure 4 As shown, at this time, the milling cutter assembly 11 is located in the milling area 100. If milling is required, the first displacement assembly 21, the second displacement assembly 22, and the third displacement assembly 23 of the displacement mechanism are controlled to move. Preferably, a plurality of positioning sensors can be provided to communicate with the control system 7, so that the displacement of the displacement mechanism can be better positioned. Of course, the required displacement amount can also be preset. In the actual displacement process, the displacement in the Z-axis direction can be performed first as required, and after reaching the set height, the movement in the X-axis direction can be performed, so that it corresponds to the position of a certain part to be milled, and then the displacement in the Y-axis direction is performed to adjust the appropriate milling distance. The first driving assembly 13 is used to control the rotation start and stop of the milling cutter assembly. The unlocking assembly 4 is arranged at the rear of the milling cutter assembly 11, and the unlocking assembly 4 is located above the first driving assembly 13. The three are arranged together on the first displacement assembly 21, that is, the three can not only be displaced in the Z-axis direction on the first displacement assembly 21, but also be driven as a whole to displace on the second displacement assembly 22 with the first displacement assembly 21. At the same time, the three are arranged together with the first displacement assembly 21 on the second displacement assembly 22, and can not only move in the X-axis direction, but also be driven as a whole to displace on the third displacement assembly 23 with the second displacement assembly 22, that is, the whole is displaced in the Y-axis direction.
[0081] See also Figures 5 to 8As shown, at this time, the milling cutter assembly 11 is located in the milling cutter replacement area, and is specifically driven by the displacement mechanism to be transported to the milling cutter replacement area, and the milling cutter is replaced in the milling cutter replacement area, and the worn or damaged milling cutter assembly is replaced with a spare milling cutter assembly, and the two can be arranged one above the other to avoid mutual interference;
[0082] Furthermore, combined with Figure 7 and Figure 8 It can be seen that the limiting and fixing component 6 of this example may include a limiting channel 61 for limiting and allowing the part to be milled to pass through, and at least one limiting fastener 62 arranged on the side of the limiting channel 61. When the part to be milled is inserted into the limiting channel 61, the part to be milled can be pushed or pressed and fastened by the limiting fastener 62. For example, the fastening can be achieved by using equipment such as a cylinder. No specific limitation is made here, as long as the part to be milled can be firmly fixed.
[0083] Below Figures 1 to 8 Based on the combination Figures 9 to 14 The following explains how the locking component 12 and the unlocking component 4 of this example work and how to realize automatic replacement of the milling cutter. When the locking component 12 is in the locked state, the elastic member 121 will be in the extended state, that is, the elastic member 121 pulls the locking member 122 to make it tend to stay away from the accommodating chamber 1241. In this way, it is only necessary to embrace the locking mating part 123 on the milling cutter fixing member 112. Once unlocking is required, the second driving component 41 of the unlocking component 4 is activated to support one end of the locking shaft 1221 and move the locking shaft 1221 toward the accommodating chamber 1241. In this process, the elastic member 121 is compressed by force, and the locking member 122 is locked. The elastic buckle 1222 connected to the shaft 1221 continuously moves along the guide inclined surface 12411. During the movement, due to the existence of the inclined surface of the guide inclined surface 12411, the elastic buckle 1222 continuously returns to the relaxed state under the action of its own elastic force until it is out of the engaged state and away from the locking fitting portion 123, thereby releasing the milling cutter assembly 11, thereby achieving unlocking. At the same time, in the unlocked state, it is preferred that the second driving assembly 41 (for example, a cylinder, preferably a cylinder with a large force, such as a double-force cylinder, etc.) is always pressed against the locking shaft 1221;
[0084] Further, when the milling cutter assembly 11 needs to be replaced, we first move it to the position as shown in the figure. Figure 5The state shown; that is, the milling cutter assembly 11 is moved to the milling cutter replacement area. At this time, the limiting groove 1121 on the milling cutter fixing member 112 is clamped with the support member 3, and the support member 3 extends two claws to clamp into the limiting groove 1121, thereby limiting the freedom of the milling cutter assembly 11 or the spare milling cutter assembly 5 in the direction of the rotation axis of the milling cutter 111 (it can be clamped from the side when clamped, and can be withdrawn from the side). In this way, when the elastic buckle 1222 on the locking member 122 withdraws from the matching relationship with the locking matching part 123 on the milling cutter fixing member 112, the milling cutter assembly 11 can be stably supported. On the support member 3, the displacement mechanism can drive the remaining locking components to displace and then move to the rear of the spare milling cutter assembly 5, and approach it until the locking mating part on the spare milling cutter assembly 5 enters the elastic buckle 1222 on the locking member 122. When the preset position is reached, the force of the second drive assembly 41 is removed, so that the locking member 122 can embrace the spare milling cutter assembly under the action of the restoring force of the elastic member 121, and then the support member supporting the spare milling cutter assembly is withdrawn from the side to complete the automatic replacement of the milling cutter. This process does not require human participation, greatly liberates manpower and improves work efficiency.
[0085] See also Figures 15 to 19 As shown, it exemplarily shows the cutting edge angle and form of the milling workpiece 9 milled by the milling machine of this example, for example Fig.15 It is a cutting edge form with a combination of various angles. Fig.16 The cutting edge is rounded at various angles. Fig.17 and Fig.19 They are blade forms with different angles. Fig.18 It is a cutting edge form that is a combination of angles and chamfers. Practice shows that the milling machine of the utility model can at least realize cutting edge milling of 20°-90°, and can also combine cutting edges in various forms such as chamfers, thereby improving product diversity.
[0086] In summary, based on the problems existing in the prior art when grinding the scraper, the utility model innovatively provides a method of locking the milling cutter and driving the milling cutter to rotate by using a locking mechanism, and then finally driving the milling cutter to rotate by driving the locking mechanism to rotate, so as to realize the milling of the milling cutter on the milling workpiece. The structure is set in this way, first, by driving the milling cutter to move to realize the milling of the workpiece to be milled, and at the same time cooperating with the displacement mechanism that can reach any position in the preset area, it is convenient to perform multi-directional and multi-angle milling on the workpiece to be milled, which is conducive to realizing cutting edges of more angles and more types of forms. The cutting edge has good diversity; secondly, the milling cutter is locked by a locking mechanism and driven to rotate, so that when the locking mechanism is unlocked, the milling cutter can be replaced. When further coordinated with the displacement mechanism, the milling cutter replacement area can be easily reached and the milling cutter can be quickly replaced; thirdly, by driving the milling cutter to move to realize the milling of the workpiece to be milled, it is beneficial to set multiple milling positions (if the workpiece to be milled moves and the milling cutter only rotates in place, it is difficult to make multiple workpieces to be milled in sequence), that is, it is beneficial to realize that one device can mill multiple workpieces to be milled in sequence, thereby improving work efficiency.
