Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cutting head processing, in particular to a cutting head processing tool and cutting head processing equipment. BACKGROUND

[0002] The cutting head is an important component of the heading machine, has the function of breaking and stripping coal and rock. It is usually installed at the front end of the cantilever of the heading machine, and realizes the cutting of coal and rock through rotation and feeding movement. Its structure generally includes a cutting head body, a cutting tooth seat, a material guide plate and the like. When automatic welding is carried out, it is necessary to transfer and position between different riveting and welding stations. Due to the shape and structure of the cutting head, it is difficult to safely hoist and transfer. The different riveting and welding stations are all provided with a positioner to adjust the processing angle of the cutting head. After each hoisting and transfer of the cutting head, the positioner needs to be re-adjusted so that the cutting head is located at the correct angle, which is very troublesome. SUMMARY

[0003] The utility model aims at least to solve one of the technical problems of the cutting head hoisting and transfer in the prior art or related art.

[0004] Therefore, the utility model provides a cutting head processing tool in the first aspect of embodiments.

[0005] The utility model provides a cutting head processing equipment in the second aspect of embodiments.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a cutting head processing tool for cutting head processing equipment, and the cutting head processing equipment includes at least one positioner turntable, the first connector is arranged on the positioner turntable, the cutting head processing tool includes: a tray, the tray is provided with the second connector, the second connector is matched with the first connector; a lifting appliance is detachably connected with the tray; wherein the tray is used for carrying the cutting head, when the tray is placed on the positioner turntable, the first connector and the second connector are coupled; the lifting appliance is used for connecting a hoisting device, when the lifting appliance is connected with the tray, the hoisting device can realize the hoisting of the cutting head on the positioner turntable or the transfer of the cutting head among multiple positioner turntables.

[0007] According to the cutting head processing tool provided by the utility model, the tray can be placed on the positioner turntable and carry the cutting head, the first connector is arranged on the positioner turntable, the second connector is arranged on the tray, and the positioning of the tray and the positioner turntable is realized through the coupling of the first connector and the second connector. The lifting appliance is connected with the hoisting device, the tray and the cutting head are hoisted together through the hoisting device after the lifting appliance and the tray are connected, the cutting head is hoisted to the positioner turntable, when the cutting head processing equipment includes multiple positioner turntables, the cutting head processing tool can also realize the transfer and positioning of the cutting head among the multiple positioner turntables.

[0008] The first connector is located on the upward side of the positioner turntable, and the second connector is located on the downward side of the tray. When the tray is placed on the positioner turntable, the first connector and the second connector are coupled to fix the position of the tray on the positioner turntable. When the positioner turntable rotates, the tray rotates with the positioner turntable, and the cutting head carried by the tray rotates, thereby realizing the positioning of the cutting head by the positioner turntable and the adjustment of the posture of the cutting head.

[0009] Specifically, the first connector can be a plurality of combined positioning pins, and the second connector can be a plurality of combined positioning holes matched with the first connector; or the first connector and the second connector are a mortise and tenon structure matched with each other.

[0010] When the cutting head machining device includes a plurality of positioner turntables, a first connector corresponding in position is arranged on each positioner turntable. The positioner turntables are arranged to have the same rotation angle and posture. During the transfer of the cutting head on different positioner turntables, the coupling of the first connector and the second connector can keep the cutting head on different positioner turntables to have the same machining angle and posture, thereby realizing the positioning of the cutting head during the transfer.

[0011] In other words, when the cutting head machining device has a plurality of positioners and positioner turntables and is located at different machining stations, all the positioner turntables are adjusted to have the same rotation angle and posture. Through positioning, the machining angle and posture of the cutting head can remain unchanged during the circulation of the cutting head between different stations, and only the machining device is changed.

[0012] The lifting appliance and the tray are detachably connected. When the cutting head needs to be lifted, the cutting head is first lifted onto the tray, and then the lifting appliance is connected to the tray. The whole is lifted and transferred by the lifting device. After the tray is placed on the positioner turntable, the lifting appliance can be detached so that the machining device can directly weld or assemble the cutting head. After the welding or assembly station is machined, the cutting head needs to be circulated to the next station for machining. At this time, the lifting appliance and the tray are assembled and connected, and the whole is transferred to the positioner turntable of the next station by the lifting device again. After positioning, the lifting appliance is detached, and the machining device is operated to machine the cutting head.

[0013] That is, the tray does not affect the machining of the cutting head by the cutting head machining device. After the cutting head is lifted onto the tray, the cutting head does not need to be removed from the tray during the whole lifting, machining and transferring process. The lifting appliance affects the machining of the cutting head, so the lifting appliance is connected to the tray during lifting and transferring, and the lifting appliance and the tray are separated during machining of the cutting head.

[0014] In some embodiments, the tray further comprises a plurality of first connectors, and the lifting device further comprises a plurality of second connectors, the first connectors and the second connectors being detachably connected.

[0015] In this embodiment, the tray is provided with a plurality of first connectors and the lifting device is provided with a plurality of second connectors, so that the tray and the lifting device are detachably connected. It can be understood that the plurality of detachable first connectors and second connectors can disperse the force at the connection between the tray and the lifting device during hoisting, thereby forming a plurality of force points and maintaining the overall stability during hoisting.

[0016] In some embodiments, the lifting device further comprises: a lifting portion for connecting a hoisting device; and a plurality of connecting rods, one end of each of the connecting rods being connected to the lifting portion, and the other end of each of the connecting rods being provided with a second connector.

[0017] In this embodiment, the lifting device comprises a lifting portion for connecting a hoisting device, and a plurality of connecting rods, one end of each of the connecting rods being connected to the lifting portion, and the other end of each of the connecting rods being provided with a second connector.

[0018] During hoisting, the hoisting device is connected to the lifting portion, the first connectors and the second connectors are connected, and the lifting portion, the tray and the plurality of connecting rods form a containing space for the cutting head, so that the cutting head processing tool is more secure and stable during hoisting and transportation.

[0019] In some embodiments, the tray further comprises: a stopper, the stopper being at least partially inserted into the cutting head or the cutting head being at least partially inserted into the stopper; and a bottom plate, the bottom plate being fixedly connected to the stopper, the stopper being located on a side of the bottom plate facing the lifting device, the side of the bottom plate facing the lifting device being further provided with a plurality of first connectors, and a second connector being provided on a side of the bottom plate facing away from the lifting device.

[0020] In this embodiment, the tray further comprises a stopper for fixing the cutting head and a bottom plate, the stopper can fix the cutting head by being inserted into the cutting head, or the cutting head can be fixed by being inserted into the stopper, the stopper and the plurality of first connectors being located on a side of the bottom plate facing the lifting device, and a second connector being provided on a side of the bottom plate facing away from the lifting device.

[0021] It can be understood that the cutting head does not need to be removed from the tray during hoisting, processing and transportation of the cutting head. By providing the stopper, the cutting head can be fixed more firmly on the tray, and the relative position between the cutting head and the tray can be maintained even under the force of the cutting head during processing. In addition, the cutting head is a rotating part of the tunneling machine for directly cutting rock, and the head is covered with cutters. By fixing the bottom of the cutting head with the stopper and processing the cutting head with the head facing upward, the cutting head is more secure.

[0022] The bottom plate is located below the stopper and has good load bearing, preferably made of steel, cast iron or other materials. The tensile strength of such materials is usually greater than the shear strength. The first connecting piece is arranged above the bottom plate. When lifting, the tray and cutting head are lifted by the tensile stress between the first connecting piece and the bottom plate, avoiding the case that the first connecting piece is arranged on the side of the outer edge of the bottom plate, and the shear stress is too large when lifting, thereby improving the service life of the tray.

[0023] When the tray is placed on the positioner turntable, the bottom plate is attached to the positioner turntable, and the second connector is located below the bottom plate, making it easier to position the tray and the positioner turntable.

[0024] Further, the stopper can be a boss structure that extends into the cutting head and abuts the inner wall of the cutting head, or a groove structure that abuts the outer wall of the cutting head.

[0025] In some embodiments, the bottom plate is a circular plate structure, and the plurality of first connecting pieces are arranged on the outer edge of the bottom plate and evenly distributed along the circumference of the bottom plate.

[0026] In this embodiment, the bottom plate is a circular plate structure, and the plurality of first connecting pieces are evenly arranged along the circumference of the outer edge of the bottom plate.

[0027] It can be understood that the cutting head is rotated and fed to cut the coal and rock, so it can be approximated as a rotationally symmetric body. The circular plate structure of the bottom plate can better adapt to the shape of the cutting head, and the first connecting pieces can be evenly arranged along the circumference of the outer edge of the bottom plate to make the space formed by the lifting part, the bottom plate and the plurality of connecting rods more suitable for accommodating the cutting head. And the evenly distributed connecting points of the lifting device and the tray optimize the distribution of the connecting points of the lifting device and the tray, and the stress on the tray is more uniform when lifting.

[0028] In some embodiments, the lifting part is a circular plate structure, and the axis of the lifting part coincides with the axis of the bottom plate, and the projection of the lifting part on the plane where the bottom plate is located is substantially coincident with the projection of the bottom plate.

[0029] In this embodiment, the lifting part is similar to the bottom plate in that it is a circular plate structure, and the diameters of their circular cross sections are substantially the same and are arranged along the same axis and are parallel to each other. Such a structure not only optimizes the accommodation space, but also optimizes the stress balance of the plurality of connecting rods. That is, the lifting part, the bottom plate and the plurality of connecting rods form a cylindrical space that is more suitable for accommodating the cutting head, and the cutting head machining tool has a rotationally symmetric body structure, and all the connecting rods are subjected to substantially the same stress.

[0030] In some embodiments, the connecting rods are perpendicular to the plane in which the bottom plate is located, and the first connecting pieces, the second connecting pieces and the connecting rods are the same in number and are arranged one-to-one.

[0031] In the technical solution, the bottom plate is provided with a plurality of first connecting pieces, each first connecting piece is detachably connected with a second connecting piece, and each second connecting piece is arranged on a connecting rod. The plurality of connecting rods, the plurality of second connecting pieces and the plurality of first connecting pieces have the same number. It can be understood that, in this way, each connecting rod has the same length and the same direction, each first connecting piece has a corresponding second connecting piece for detachable connection, and the overall structure has no redundancy.

[0032] In some technical solutions, the stopper and the bottom plate are arranged along the same axis.

[0033] In the technical solution, the axis of the stopper and the axis of the bottom plate coincide. It can be understood that, in the technical solution, the mechanical structure of the tray mainly includes the bottom plate and the stopper, the cutting head has an axisymmetric structure, and the cutting head is fixed to the bottom plate through the stopper. Therefore, the axes of the bottom plate, the stopper, the tray and the cutting head approximately coincide. When hoisting, the tray is more likely to maintain a horizontal state under the action of the connecting rods uniformly distributed in the circumferential direction. On the other hand, when the tray is installed and placed on the rotating disc of the positioner, the axis of the rotating disc of the positioner only needs to coincide with the axis of the tray, so that the cutting head can be conveniently rotated around the axis, thereby facilitating machining.

[0034] In some technical solutions, the connecting rods are arranged in parallel.

[0035] In the technical solution, the connecting rods are arranged in parallel.

[0036] It can be understood that, when the cutting head machining tool is lifted and moved horizontally, the horizontal force can only be transmitted from the lifting part to the tray and the cutting head through the connecting rods. Therefore, the connecting rods will be subjected to horizontal forces in opposite directions, causing the connecting rods to deform. The auxiliary rods can reduce the deflection of the connecting rods under stress, and the overall rigidity of the cutting head machining tool is better.

[0037] Further, when a plurality of auxiliary rods are arranged between adjacent connecting rods, the plurality of auxiliary rods should not be parallel. A parallelogram structure has a high degree of freedom and is more likely to deform under stress. By arranging the plurality of auxiliary rods between adjacent connecting rods to be non-parallel, the degree of freedom of the cutting head machining tool is reduced, and the structure is more stable.

[0038] In some technical solutions, the plurality of auxiliary rods at least form a polygon parallel to the plane in which the bottom plate is located.

[0039] In the technical solution, the plurality of auxiliary rods at least enclose a polygon, and the polygon is parallel to the plane on which the base plate lies. It can be understood that the lifting part and the base plate are parallel to each other, and the connecting rods connect the lifting part and the base plate. Therefore, the connecting points of one end of the plurality of connecting rods on the lifting part form a polygon, and the connecting points of the other end of the plurality of connecting rods on the base plate also form a polygon, and the two polygons are approximately the same. In the middle of the plurality of connecting rods, at least one polygon bracket formed by the plurality of auxiliary rods is added to reinforce and transition, so that the relative positions of the plurality of connecting rods are stable, and the deformation caused by the stress of a single connecting rod is reduced. The stress concentration problem caused by the deformation of a single connecting rod is improved, the safety is improved, and the service life is increased.

[0040] In some technical solutions, the number of the first connectors and the second connectors is two, and the first connectors and the second connectors are arranged correspondingly.

[0041] In the technical solution, the first connectors and the second connectors are arranged oppositely and can be positioned by plugging, and the number of the first connectors and the second connectors is two. When the two sets of first connectors and second connectors are coupled, the tray and the positioner turntable cannot rotate.

[0042] When only one set of cylindrical pin hole structure of the first connector and the second connector is matched, the positioner turntable and the tray cannot be prevented from rotating around the cylindrical pin hole structure, and more than two sets of first connectors and second connectors are redundant. When the lifting device cannot drive the cutting head machining tool to rotate greatly, two sets of first connectors and second connectors are arranged to make the structure of the cutting head machining tool more simple.

[0043] Further, the first connector is a positioning pin, and the second connector is a positioning hole. The positioning pin is arranged as a protruding structure on the side of the positioner turntable facing upward, and the positioning hole is arranged on the side of the tray facing downward. In this way, the bottom of the tray has no protrusion and can be safely placed on the ground.

[0044] In some technical solutions, the second connecting piece includes a pneumatic bolt, and the first connecting piece includes a waist-shaped hole, and the pneumatic bolt and the waist-shaped hole are matched.

[0045] In the technical solution, the second connecting piece includes a pneumatic bolt, and the first connecting piece includes a waist-shaped hole matched with the pneumatic bolt. It can be understood that the pneumatic bolt is adopted, and automatic clamping can be realized through pneumatic control, without manual operation, thereby improving the safety during hoisting.

[0046] Embodiments of the second aspect of the application provide a cutting head machining device, comprising: at least one positioner turntable, wherein the positioner turntable is provided with a first connector; and any one of the cutting head machining tools described above, which is used for hoisting the cutting head on the positioner turntable or transferring the cutting head among a plurality of positioner turntables.

[0047] According to the cutting head machining device provided in the application, the cutting head machining device comprises a cutting head machining tool for carrying the cutting head on the dial plate of the positioner and at least one dial plate of the positioner. The cutting head machining tool can be used for hoisting the cutting head, and when the dial plate of the positioner is multiple, the cutting head machining tool can be used for transferring the cutting head between the multiple dial plates of the positioner.

[0048] Since the cutting head machining device comprises any one of the cutting head machining tools described above, the cutting head machining device has the beneficial effects of any one of the cutting head machining tools described above, which will not be repeated here.

[0049] The multiple dial plates of the positioner can be arranged at different stations of the cutting head machining device, and the cutting head can be transferred and positioned between the different stations by the cutting head machining tool.

[0050] In some technical solutions, the cutting head machining device further comprises at least one positioner, the at least one positioner and the at least one dial plate of the positioner are correspondingly arranged, and are used for adjusting the machining angle of the cutting head.

[0051] In the technical solution, each dial plate of the positioner is correspondingly arranged on one positioner, and is used for adjusting the machining angle of the cutting head. It can be understood that the cutting head machining device comprises devices at multiple stations, and each station is provided with a positioner, and the positioner and the dial plate of the positioner are used for adjusting the machining angle of the cutting head.

[0052] The additional aspects and advantages of the present application will become apparent from the following description, or will be appreciated by practice of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0064] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the utility model, the embodiments of the utility model are further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0065] In the following description, many specific details are set forth in order to provide a thorough understanding of the application, however, embodiments of the application can also be implemented in other manners different from those described herein, therefore, the protection scope of the application is not limited to the specific embodiments disclosed below.

[0066] The following description refers to the accompanying drawings. Figures 1 to 6 Some embodiments according to the utility model are described below.

[0067] As Figure 1 , Figure 2As shown, the cutting head machining tool 100 proposed in this embodiment includes a tray 102 and a lifting tool 104. The tray 102 can be placed on the positioner turntable 204 and carries the cutting head 400. The positioner turntable 204 has a first connector 206, and the tray 102 has a second connector 1022. The positioning of the tray 102 and the positioner turntable 204 is achieved through the coupling of the first connector 206 and the second connector 1022. The lifting tool 104 is connected to the lifting device 300. After the lifting tool 104 and the tray 102 are connected, the tray 102 and the cutting head 400 can be lifted together through the lifting device 300, realizing the hoisting of the cutting head 400 to the positioner turntable 204. When the cutting head machining equipment 200 includes multiple positioner turntables 204, the cutting head machining tool 100 of the present application can also realize the transfer and positioning of the cutting head 400 between multiple positioner turntables 204.

[0068] Among them, the first connector 206 is located on the upward side of the positioner turntable 204, and the second connector 1022 is located on the downward side of the tray 102. When the tray 102 is placed on the positioner turntable 204, the first connector 206 and the second connector 1022 are coupled to fix the position of the tray 102 on the positioner turntable 204. When the positioner turntable 204 rotates, the tray 102 rotates with the positioner turntable 204, driving the cutting head 400 carried thereby to rotate, realizing the positioning of the cutting head 400 by the positioner turntable 204 and the adjustment of the attitude of the cutting head 400.

[0069] Specifically, the first connector 206 can be a plurality of combined positioning pins, and the second connector 1022 can be a plurality of combined positioning holes matched with the first connector 206; or the first connector 206 and the second connector 1022 are a mortise and tenon structure matched with each other.

[0070] Among them, when the cutting head machining equipment 200 includes multiple positioner turntables 204, each positioner turntable 204 is provided with a corresponding first connector 206. By setting different positioner turntables 204 to the same angle and attitude, the cutting head 400 can maintain the same machining angle and attitude on different positioner turntables 204 during transfer, realizing the positioning of the cutting head 400 during transfer.

[0071] In other words, when the cutting head machining equipment 200 has multiple sets of positioners 202 and positioner turntables 204 and is located in different machining stations. By adjusting all positioner turntables 204 to the same angle and attitude, the machining angle and attitude of the cutting head 400 can be kept unchanged during circulation between different stations through positioning, and only the machining equipment is changed.

[0072] The lifting appliance 104 and the tray 102 are detachably connected. When the cutting head 400 needs to be hoisted, the cutting head 400 is first hoisted to the tray 102, and then the lifting appliance 104 is connected with the tray 102, and the whole is hoisted and transported by the hoisting device 300. After the tray 102 is placed on the positioner turntable 204, the lifting appliance 104 can be detached, so that the machining equipment can directly weld or assemble the cutting head 400. After the welding or assembly station is processed, the cutting head 400 needs to be transferred to the next station for further processing. At this time, the lifting appliance 104 and the tray 102 are assembled and connected, and then the whole is transported to the positioner turntable 204 of the next station by the hoisting device 300. After positioning, the lifting appliance 104 is detached, and the machining equipment processes the cutting head 400.

[0073] That is, the tray 102 does not affect the processing of the cutting head 400 by the cutting head machining equipment 200. After the cutting head 400 is hoisted to the tray 102, the cutting head 400 does not need to be removed from the tray 102 during the whole hoisting, processing and transporting process. The lifting appliance 104 will affect the processing of the cutting head 400, so the lifting appliance 104 is connected with the tray 102 during hoisting and transporting, and the lifting appliance 104 and the tray 102 are separated during processing of the cutting head 400.

[0074] In some embodiments, the tray 102 is provided with a plurality of first connecting pieces 1024 and a plurality of second connecting pieces 1046 on the lifting appliance 104 to achieve detachable connection. It can be understood that the plurality of detachable first connecting pieces 1024 and second connecting pieces 1046 can disperse the stress at the connection between the tray 102 and the lifting appliance 104 during hoisting, forming a plurality of stress points to maintain the overall stability during hoisting.

[0075] As shown in Figure 3 In some embodiments, the lifting appliance 104 includes a lifting part 1042 connected with the hoisting device 300, and a plurality of connecting rods 1044 connected with one end of the lifting part 1042, and a second connecting piece 1046 is arranged at the other end of each connecting rod 1044.

[0076] During hoisting, the hoisting device 300 is connected with the lifting part 1042, and the first connecting piece 1024 and the second connecting piece 1046 are connected. The lifting part 1042, the tray 102 and the plurality of connecting rods 1044 form a containing space for the cutting head, so that the cutting head machining tooling 100 is more safe and stable during hoisting and transporting.

[0077] As shown in Figure 4 , Figure 5As shown, in some embodiments, the tray 102 further comprises a stopper 1026 for fixing the cutting head 400 and a bottom plate 1028. The stopper 1026 can fix the cutting head 400 by extending into the cutting head 400, or the cutting head 400 can fix the stopper 1026 by extending into the stopper 1026. The stopper 1026 is arranged on the side of the bottom plate 1028 facing the lifting device 104, and the side of the bottom plate 1028 away from the lifting device 104 is provided with a second connecting piece 1046.

[0078] It can be understood that, since the cutting head 400 does not need to be removed from the tray 102 during hoisting, processing and transportation of the cutting head 400, the cutting head 400 can be fixed more firmly on the tray 102 by arranging the stopper 1026. During processing, even under the force of the cutting head 400, the relative position between the cutting head 400 and the tray 102 can still be fixed. In addition, the cutting head 400 is a rotating part of the tunneling machine for directly cutting rock. The head is full of cutters. The bottom of the cutting head 400 is fixed by the stopper 1026, and the head of the cutting head 400 is processed upward, which is safer.

[0079] The bottom plate 1028 is below the stopper 1026 and has good bearing capacity. It is preferably made of steel, cast iron or the like. The tensile strength of such materials is usually greater than the shear strength. The first connecting piece 1024 is arranged above the bottom plate 1028. When hoisting, the tray 102 and the cutting head 400 are lifted by the tensile stress between the first connecting piece 1024 and the bottom plate 1028, avoiding the case that the first connecting piece 1024 is arranged on the side of the outer edge of the bottom plate 1028, and the shear stress is too large when hoisting, thereby improving the service life of the tray 102.

[0080] When the tray 102 is placed on the variable position machine turntable 204, the bottom plate 1028 is in contact with the variable position machine turntable 204, and the second connecting piece 1022 is below the bottom plate 1028, which is more convenient for positioning the tray 102 and the variable position machine turntable 204.

[0081] Further, the stopper 1026 can be a boss structure extending into the cutting head 400 and abutting the inner wall of the cutting head 400, or a groove structure abutting the outer wall of the cutting head 400.

[0082] In some embodiments, the bottom plate 1028 has a circular plate structure, and a plurality of first connecting pieces 1024 are arranged uniformly along the outer edge of the bottom plate 1028.

[0083] It can be understood that the cutting head 400 is realized by rotating and feeding to cut the coal rock, and therefore can be approximately regarded as a rotationally symmetrical body. The bottom plate 1028 in a circular plate structure can better adapt to the shape of the cutting head 400. By uniformly arranging the first connecting members 1024 circumferentially on the outer edge of the bottom plate 1028, the space formed among the lifting part 1042, the bottom plate 1028 and the plurality of connecting rods 1044 can be more suitable for accommodating the cutting head 400. And the circumferentially uniform arrangement optimizes the distribution of the connecting points of the lifting appliance 104 and the tray 102, and the tray 102 is more evenly stressed during lifting.

[0084] In some embodiments, optionally, the lifting part 1042 is also in a circular plate structure similar to the bottom plate 1028, and the diameters of the circular cross sections of the two are substantially the same, and they are arranged along the same axis and parallel to each other. Such a structure not only optimizes the accommodation space, but also optimizes the force balance of the plurality of connecting rods 1044. That is, the space formed among the lifting part 1042, the bottom plate 1028 and the plurality of connecting rods 1044 is a cylindrical space, which is more suitable for accommodating the cutting head, and the cutting head machining tool 100 has a rotationally symmetrical body structure, and all the connecting rods 1044 are substantially equally stressed.

[0085] In some embodiments, optionally, the bottom plate 1028 is provided with a plurality of first connecting members 1024, each first connecting member 1024 is detachably connected with a second connecting member 1046, and each second connecting member 1046 is arranged on a connecting rod 1044. The number of the plurality of connecting rods 1044, the plurality of second connecting members 1046 and the plurality of first connecting members 1024 is the same. It can be understood that such a design can make each connecting rod 1044 have the same length and consistent direction, each first connecting member 1024 has a corresponding second connecting member 1046 for detachable connection, and the overall structure is not redundant.

[0086] In some embodiments, optionally, the axis of the stopper 1026 coincides with the axis of the bottom plate 1028. It can be understood that in this scheme, the mechanical structure of the tray 102 mainly includes the bottom plate 1028 and the stopper 1026, the cutting head 400 is similar to an axially symmetrical structure, and is placed perpendicularly to the tray 102, so the stopper 1026 also has an axially symmetrical structure, the cutting head 400 is fixed on the bottom plate 1028 through the stopper 1026, that is, the axes of the bottom plate 1028, the stopper 1026, the tray 102 and the cutting head 400 approximately coincide. During hoisting, the tray 102 is more likely to maintain a horizontal state under the action of the circumferentially uniformly distributed connecting rods 1044. On the other hand, when the tray 102 is installed and placed on the variable position machine turntable 204, only the axis of rotation of the variable position machine turntable 204 needs to coincide with the axis of the tray 102, so that the cutting head 400 can be conveniently rotated around its axis for machining.

[0087] In some embodiments, optionally, an auxiliary rod 1048 is arranged between adjacent connecting rods 1044, and the auxiliary rods 1048 between adjacent connecting rods 1044 are not parallel. It can be understood that when the cutting head machining tool 100 is hoisted and moved horizontally, the horizontal force can only be transmitted from the hoisting part 1042 to the tray 102 and the cutting head 400 through the connecting rods 1044. Therefore, the connecting rods 1044 at both ends will be subjected to horizontal forces in opposite directions, causing the connecting rods 1044 to deform. The auxiliary rods 1048 can reduce the deflection of the connecting rods 1044 caused by the force, and make the rigidity of the cutting head machining tool 100 better.

[0088] Further, when a plurality of auxiliary rods 1048 are arranged between adjacent and parallel connecting rods 1044, the plurality of auxiliary rods 1048 should be avoided to be parallel. Because the parallelogram structure has a high degree of freedom, the force is more likely to deform. By arranging the plurality of auxiliary rods 1048 between adjacent connecting rods 1044 to be non-parallel, the degree of freedom of the cutting head machining tool 100 is reduced, and the structure is more stable.

[0089] In some embodiments, optionally, the plurality of auxiliary rods 1048 at least enclose a polygon, and the polygon is parallel to the plane where the bottom plate 1028 is located. It can be understood that the hoisting part 1042 and the bottom plate 1028 are parallel to each other, and the connecting rods 1044 connect the hoisting part 1042 and the bottom plate 1028. Therefore, the connection points of one end of the plurality of connecting rods 1044 on the hoisting part 1042 form a polygon, and the connection points of the other end of the plurality of connecting rods 1044 on the bottom plate 1028 also form a polygon, and the two polygons are approximately the same. In the middle of the plurality of connecting rods 1044, at least one polygon bracket formed by the plurality of auxiliary rods 1048 is added to reinforce and transition, so that the relative position between the plurality of connecting rods 1044 is stable, and the deformation of the single connecting rod 1044 caused by the force is reduced. The stress concentration problem caused by the deformation of the single connecting rod 1044 is improved, the safety is improved, and the service life is increased.

[0090] In some embodiments, optionally, the first connector 206 and the second connector 1022 are opposite in position, can be connected and positioned, and the number is two groups. When the two groups of first connector 206 and second connector 1022 are coupled, the tray 102 and the displacement machine turntable 204 cannot rotate.

[0091] When only one set of cylindrical pin hole structure first connector 206 and second connector 1022 are matched, it cannot prevent the positioner turntable 204 and the tray 102 from rotating around the cylindrical pin hole structure, and more than two sets of first connector 206 and second connector 1022 are redundant. In the lifting device 300, the cutting head machining tool 100 does not rotate greatly under the action of the lifting device 300, and two sets of first connector 206 and second connector 1022 are arranged to make the structure of the cutting head machining tool 100 more compact.

[0092] Further, the first connector 206 is a positioning pin, and the second connector 1022 is a positioning hole. The positioning pin is arranged as a protruding structure on the upward side of the positioner turntable 204, and the positioning hole is arranged on the downward side of the tray 102. In this way, the bottom of the tray 102 is not protruding and can be safely placed on the ground.

[0093] In some embodiments, optionally, the second connecting piece 1046 includes a pneumatic latch 1049, and the first connecting piece 1024 includes a waist-shaped hole 1029 matched with the pneumatic latch 1049. It can be understood that the pneumatic latch 1049 is adopted, and automatic clamping can be realized through pneumatic control, without manual operation, thereby improving the safety in the lifting process.

[0094] As shown in FIG. 1, Figure 6 Another embodiment of the present application provides a cutting head machining device 200, which includes a cutting head machining tool 100 for carrying a cutting head on a positioner turntable 204, and at least one positioner turntable 204. The cutting head machining tool 100 can be used for lifting the cutting head, and when the positioner turntable 204 is multiple, the cutting head machining tool 100 can be used for transferring the cutting head between the multiple positioner turntables 204.

[0095] Since the cutting head machining device 200 includes any of the above cutting head machining tools 100, it has the beneficial effects of any of the above cutting head machining tools 100, which will not be repeated here.

[0096] Among them, the multiple positioner turntables 204 can be arranged at different stations of the cutting head machining device 200, and the cutting head 400 can be transferred and positioned between different stations through the cutting head machining tool 100.

[0097] In some embodiments, optionally, each positioner turntable 204 is installed on a positioner 202, which is used to adjust the machining angle of the cutting head 400. It can be understood that the cutting head machining device 200 includes devices on multiple stations, and each station is equipped with a positioner 202. The positioner 202 and the positioner turntable 204 cooperate to adjust the machining angle of the cutting head 400.
