Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In embodiments of the invention, where the context requires otherwise, the use of directional terms such as "upper, lower, top and bottom" is generally intended in the orientation shown in the drawings or the positional relationship of the various components in a vertical, vertical or gravitational orientation.
The invention will be described in detail below with reference to exemplary embodiments and with reference to the accompanying drawings.
As shown in fig. 1 to 7, a positioning and clamping system 100 for positioning and clamping a boom 200 of an aerial work machine disposed in a horizontal machine tool is provided according to a first exemplary embodiment of the present invention.
It should be noted that the horizontal machine tool may be a horizontal boring machine, and the component arrangement manner in the positioning and clamping system 100 is determined based on a machine coordinate system of the horizontal machine tool (i.e., X-axis, Y-axis, and Z-axis directions of the horizontal machine tool), so as to ensure that the machining area of the boom 200 is correct after the boom is positioned and clamped. The boom 200 may be a boom of different types of aerial work machines such as a crane, a pumping machine, etc.
The positioning and clamping system 100 comprises a plurality of clamp modules 1 which are arranged in a split mode, specifically, the clamp modules 1 are sequentially arranged along the X-axis direction of the machine tool, the number of the modules can be preset or adjusted according to the actual size (generally, the length of the arm support 200) of the arm support 200, the flexibility is obvious, and the universality is high.
In addition, a plurality of sets of axial clamping assemblies are provided in the plurality of clamp modules 1 to enable positioning of the clamping arm 200 along the coordinate axis directions of the respective machine tools (i.e., the X-axis direction of the machine tool, the Y-axis direction of the machine tool, and the Z-axis direction of the machine tool). Each set of axial clamping assembly comprises a positioning part, a movable pressing clamp part and an arm support placing area limited between the positioning part and the movable pressing clamp part, and the positioning part and the movable pressing clamp part in the same set of axial clamping assembly can be arranged in different clamp modules 1 according to the attached drawings. Namely, the specific arrangement mode of the positioning piece and the movable pressing piece is flexible.
In the positioning and clamping process, the arm support 200 is firstly placed in the arm support placing area, then the positioning reference is found out by using the positioning piece, and the movable press clamp piece is adjusted to clamp the arm support 200, so that the arm support 200 can be positioned and clamped from the coordinate axis directions of all machine tools in sequence. Therefore, the positioning and clamping system 100 has high automation degree, can greatly save the production input cost in the aspects of manpower configuration and the like, improves the positioning and clamping efficiency and the machine tool working efficiency, and can obviously improve the machining precision.
As can be seen from the description of the background art, a conventional simple tool for positioning and clamping an arm support includes a plurality of equal-height blocks, an L-shaped backup plate, a pressing plate, and the like, wherein when the arm support is positioned and clamped along the Y-axis direction of a machine tool, the equal-height blocks are specifically used to contact with a clamping reference (usually, a bottom surface of the arm support) of the arm support to determine a clamping surface, and then the arm support is positioned and clamped between the equal-height blocks and the pressing plate by using a clamping effect of the pressing plate. However, the arm support usually undergoes a welding process to generate a certain deformation before positioning and clamping, so when the arm support is placed on a plurality of equal-height blocks, a phenomenon that part of the equal-height blocks are not in contact with the bottom surface of the arm support may occur, and in the case of forming such a contact gap, if a clamping force along the Y-axis direction of the machine tool is applied to the arm support by using the pressing plate, the arm support may be displaced or deformed more rapidly. Obviously, no matter which kind of circumstances appears, all must reduce final machining precision, then can't satisfy the axiality requirement to each hole system of cantilever crane on the design drawing slightly, make the cantilever crane directly become the waste product by the time.
In order to solve the problems, the arm support needs to participate in the scribing process before positioning and clamping. Specifically, the surface of the boom is scribed and lofted, and an alignment reference line of a clamping procedure is found out, so that alignment of a line-to-line meter is facilitated in subsequent clamping. Otherwise, if the scribing is not performed in advance, even if the contact gap phenomenon occurs, the contact gap phenomenon cannot be perceived.
Therefore, when the existing clamping method is adopted, a three-coordinate scribing machine needs to be equipped, and when the arm support is transported to a machine tool workbench after scribing, hoisting equipment, logistics transporting equipment and the like need to be equipped, so that the equipment investment is overlarge.
By reflecting the positioning and clamping system 100 of the exemplary embodiment, the following optimization can be made to save the scribing process.
Specifically, the axial clamping assembly includes a Y-axis clamping assembly in which the positioning members include at least three Y-axis reference positioning members 13 and at least one Y-axis telescoping positioning member 14 arranged non-collinearly. The Y-axis reference positioning member 13 is a fixed rigid positioning member, and is formed with a Y-axis reference positioning surface (for example, a top end surface of the Y-axis reference positioning member 13 in the drawings) coplanar with the clamping surface of the arm support 200, and the Y-axis telescopic positioning member 14 can move telescopically along the Y-axis direction of the machine tool.
Based on the above arrangement, when positioning and clamping the boom 200 along the Y-axis direction of the machine tool, first, the clamping reference of the boom 200 (usually, the bottom surface of the boom 200 that is not deformed) is contacted with the Y-axis reference positioning surfaces of the three Y-axis reference positioning members 13 that are not arranged in a collinear manner to determine the clamping surface of the boom 200, and at this time, even if there is a contact gap between the clamping reference of the boom 200 and the Y-axis reference positioning surfaces of the other Y-axis reference positioning members, the contact gap can be compensated by adjusting the Y-axis telescopic positioning member 14, so that the boom 200 is always placed in parallel to the horizontal plane. If a movable Y-axis pressing and clamping piece in the Y-axis clamping assembly is further adopted to clamp the arm support 200, the arm support will not deviate or deform seriously.
Compared with the existing simple tool illustrated in the foregoing, the positioning and clamping system 100 of the exemplary embodiment can save the investment of a three-coordinate line drawing machine, a hoisting device, a transportation logistics device and the like, thereby saving the equipment cost and the occupied factory space. And by arranging the Y-axis telescopic positioning part 14, the position of the arm support does not need to be adjusted by repeated meter making, the time of occupying the machine tool is greatly shortened, and the utilization rate of the machine tool is effectively improved.
Since the welding deformation is mainly formed at the bottom surface of the arm support 200, the telescopic positioning members similar to the Y-axis telescopic positioning members 14 do not need to be provided in the X-axis clamping assembly and the Z-axis clamping assembly.
Specifically, the positioning element in the X-axis clamping assembly comprises an X-axis reference positioning element 11, the X-axis reference positioning element 11 is a fixedly arranged rigid positioning element, and the movable pressing element in the X-axis clamping assembly comprises an X-axis movable pressing element 12. And the positioning part in the Z-axis clamping assembly comprises a Z-axis reference positioning part 16, the Z-axis reference positioning part 16 is also a rigid positioning part fixedly arranged, and the movable pressing part in the Z-axis clamping assembly comprises a Z-axis movable pressing part 17.
Through the mutual matching of the respective positioning parts and the movable pressing clamping parts in the X-axis clamping assembly and the Z-axis clamping assembly, the clamping arm support 200 can be correspondingly positioned along the X-axis direction and the Z-axis direction of the machine tool.
The present exemplary embodiment does not limit the specific structure of the movable press-clamping piece and the Y-axis telescopic positioning piece 14. For example, the movable clamping member and the Y-axis telescopic positioning member 14 may be hydraulic driving members, and under hydraulic control, sufficient clamping force and supporting strength can be provided, so as to improve clamping stability. Fluid in the hydraulic control system may be diverted to a plurality of hydraulic drives through a multiplex valve 115 provided on the clamp module 1. Preferably, an energy storage stabilizer (for example, a nitrogen-filled energy storage stabilizer) may be further disposed in the positioning and clamping system 100, and when power of the hydraulic driving member is lost, the energy storage stabilizer can maintain the hydraulic pressure in the hydraulic driving member at a current level, so as to prevent a secondary clamping error caused by loosening of the boom 200 due to machine tool failure or unexpected power failure and power outage in a machining process, and improve system reliability.
The flexibility of the positioning and clamping system 100 can be improved through the following optimized setting.
In one embodiment, the positioning and clamping system 100 comprises a machine tool workbench 3 in a horizontal machine tool, the machine tool workbench 3 extends horizontally in the direction of the X axis of the machine tool, and a plurality of clamp modules 1 can be directly installed on the machine tool workbench 3 and can be detachably matched, so that the number of the modules can be adjusted according to the length of the arm support 200.
In one embodiment, referring to the attached drawings, in the X-axis direction of the machine tool, the fixture module 1 installed at one end of the machine tool workbench 3 is formed as a lifting module 2 partially extending out of the machine tool workbench 3, which is equivalent to extending the machine tool workbench 3, and can support the part of the boom extending out of the machine tool workbench 3 which does not need to be machined, so as to ensure that the boom 200 is stably clamped as a whole. Since the length of the machine table 3 is not increased in practice, the capital investment can also be reduced.
In one embodiment, at least part of the clamp module 1 and the machine tool workbench 3 form a sliding fit along the direction of the X axis of the machine tool, so that the clamp module 1 is suitable for being adaptively adjusted in the position of positioning and clamping the arm support 200 with different lengths. At this time, a module locking structure for locking the fixture module 1 is further required to be disposed in the positioning and clamping system 100, so as to avoid unstable clamping caused by slippage of the fixture module 1 during machining and avoid affecting machining precision.
For example, the jig module 1 includes a module base 18, and a strip-shaped base slide-fit portion extending in the X-axis direction of the machine tool is formed on the bottom surface of the module base 18, and a strip-shaped table slide-fit portion extending in the X-axis direction of the machine tool is formed on the table surface of the machine tool table 3 in a matching manner. One of the base sliding matching part and the table top sliding matching part is of a sliding groove structure, the other one of the base sliding matching part and the table top sliding matching part is of a sliding block structure, and sliding action can be achieved through matching of the sliding groove and the sliding block.
Similarly, the lifting module 2 may include a lifting base 21, and a strip-shaped base sliding fit portion extending along the X-axis direction of the machine tool is formed on the bottom surface of the lifting base 21 to form a sliding fit with the table top sliding fit portion. Moreover, lift module 2 still can be including setting up the movable folder of pressing of X axle on lifting base 21, and the movable folder of pressing of X axle can set up to sliding along the lathe X axle direction for lifting base 21, also can set up to fixed connection in order to follow lifting base 21 and slide in step on lifting base 21.
In addition, the module locking structure may include base vertical through holes formed on the module base 18 and the lift base 21, a locking bolt 111 penetrating the base vertical through holes, and a locking nut 112 coupled to one end of the locking bolt 111. By tightening the locking nut 112, the module base 18 is pressed against the machine table 3 and the lifting base 21 is pressed against the machine table 3, so that the clamping module 1 and the lifting module 2 are locked.
In one embodiment, at least part of the clamp module 1 comprises a module base 18 and two module slide seats 19 forming a sliding fit with the module base 18 along the Z-axis direction of the machine tool, one of the two module slide seats 19 is provided with a Z-axis reference positioning piece 16 and the other is provided with a Z-axis movable clamping piece 17. The size of the arm support placing area can be adjusted along the Z-axis direction of the machine tool by adjusting the distance between the two module sliding seats 19 in a sliding manner, so that the arm supports 200 with different widths can be positioned and clamped. Referring to the drawings, inter-mount slide rails 110 may be provided between the module slide mount 19 and the module base 18 to achieve the sliding motion.
Further, the positioning and clamping system 100 includes a sliding seat control mechanism capable of synchronously driving the two module sliding seats 19 to slide reversely, so as to improve the adjustment efficiency and simplify the control structure. For example, referring to the figures, the slide mount control mechanism may be a lead screw and nut mechanism 113.
On the other hand, at least part of the clamp modules 1 is provided with a guide structure 114 for guiding the boom 200 into the boom placement area. For example, referring to the drawings, the guide structure 114 may be a guide slope formed at the top of the positioning member and the movable press-clamping member.
The positioning and clamping system 100 shown in fig. 1 to 7 is provided with a first clamp module 4, a second clamp module 5, a third clamp module 6, a lifting module 2 and a machine tool workbench 3. The structures of the first clamp module 4, the second clamp module 5, the third clamp module 6 and the lifting module 2 are different, but the positioning element and the movable pressing clamp element are reasonably arranged on different modules through the component arrangement mode of the illustrated embodiment, so that at least part of the inventive concepts are obviously satisfied.
In summary, the advantages of the positioning and clamping system 100 of the present exemplary embodiment at least include: (1) three-coordinate scribing and adjusting are not needed, investment of equipment such as a three-coordinate scribing machine and the like and occupied factory area are reduced, and the utilization rate of a machine tool is improved; (2) the arm support can realize complete positioning, the processing stability is good, and the surface roughness of the machined surface is obviously improved; (3) the clamping positioning error of the arm support is less than or equal to 1.5mm, and the positioning precision is high; (4) one-person operation can be realized, and the labor cost is saved; (5) the positioning and clamping time is shortened to 5 minutes from 1 hour (workpiece surface making and workpiece adjustment) in the traditional process, so that the positioning and clamping efficiency is greatly improved; (6) the flexibility and the automation degree are high; (7) the surface roughness and the position precision of the processed hole system are far higher than the requirements of design drawings.
