With reference to fig. 1-6, the present disclosure provides a leveling platen 10, which includes a platen body 11 and a platen post group, wherein one or more leveling loops are disposed on the platen body 11, and the leveling loops correspond to end surfaces of a structural member to be leveled; the number of the pressing column groups is one or more, the pressing column groups are arranged on the disc body 11, the plurality of pressing columns 12 of each pressing column group are located on a corresponding leveling loop, and a leveling plane consistent with the end face to be leveled is constructed on the end face of the tail end of the plurality of pressing columns 12 of each pressing column group.

By adopting the leveling pressure plate 10 provided by the embodiment of the disclosure, the pressure pressed vertically downwards is utilized to avoid structural deformation caused by structures such as a mechanical cantilever and the like during leveling; the leveling face that the terminal end face of a plurality of compression columns 12 of compression column group found adapts to the terminal surface of treating the levelling of work piece for when levelling, treat that the terminal surface of levelling can receive balanced levelling pressure, moreover, compression column 12 directly sets up on disk body 11, and the installation is firm, and at the leveling in-process of pushing down, the condition that influences the leveling precision such as displacement can not take place guarantees to level the precision, and then improves the leveling effect.

In the embodiment of the present disclosure, as the name implies, the compression leg 12 is a column-shaped structural member, and one end of the compression leg, which is not disposed on the tray body 11, is the tail end. When the workpiece is pressed downwards for leveling, the end face at the tail end is used as a pressing contact end face and is directly contacted with the end face to be leveled of the workpiece.

In some embodiments, the compression posts 12 are disposed on the tray body 11 in a perpendicular manner to the tray surface of the tray body 11. So that the pressure columns 12 can exert a vertically downward pressure on the end face to be leveled.

In the embodiment of the present disclosure, the leveling ring line set on the tray 11 may be actually displayed, for example, the leveling ring line is drawn on the tray 11, or the leveling ring line is carved on the tray 11. Of course, the leveling loop may not be actually displayed (drawn or depicted), and the leveling loop may be embodied by disposing a plurality of the struts 12 of one strut group on the plate body 11.

It is understood that the leveling loop corresponds to the end face of the structural component to be leveled, and means that the shape and size of the leveling loop are determined according to the shape and structure of the end face of the structural component to be leveled. The orthographic projection of the leveling loop line on the end face of the structural part to be leveled can be ensured to be evenly distributed with the shape of the end face of the structural part to be leveled.

In a specific application, the end face of the structural part to be leveled is of a closed structure, and the size of the leveling loop can be consistent with or smaller than the external size of the end face of the structural part to be leveled. In another specific application, the end face of the structural part to be leveled is of an open structure, and the size of the leveling loop is greater than or equal to the size of the open end face and less than or equal to the external size of the end face of the structural part to be leveled. That is, it is sufficient to ensure that the end surface of the end of the pressing post 12 disposed on the leveling loop can contact the end surface to achieve pressing. The external dimension of the end face is the maximum dimension of the end face.

Alternatively, the shape of the leveling loop may correspond to the shape of the end surface of the structure to be leveled. For example, when the end surface of the structural part to be leveled is circular, the leveling loop line is in a consistent circle shape; when the end face is square, the leveling loop line is in a consistent square shape; and so on.

Alternatively, the shape of the leveling loop may not conform to the shape of the end surface of the structure to be leveled. For example, when the end surface of the structural part to be leveled is square, the leveling loop line is circular; when the end surface of the structural part to be leveled is rectangular, the leveling loop line is elliptical; when the end surface of the structural part to be leveled is round, the leveling loop line is square; and so on. In this embodiment, it is only required to ensure that the orthographic projection of the leveling loop line on the end face of the structural component to be leveled and the shape of the end face of the structural component to be leveled can form balanced distribution.

In the embodiment of the disclosure, the setting of the leveling loop is determined according to the leveling times involved in the assembly process and the end face to be leveled for each leveling. In general, the end face to be leveled with the leveling end face is of a closed structure, the end face to be leveled of the same workpiece has a similar structure, and the leveling function of the whole assembling process can be realized by arranging a pressing column group on the tray body 11.

In the embodiment of the present disclosure, for the nested structure workpiece, a plurality of leveling loops are disposed on the tray body 11, and the leveling loops correspond to the end surfaces of the multi-layer kit of the nested structure workpiece one by one.

In practical applications, the nested structure workpiece is generally divided into two parts, a first workpiece and a second workpiece, so as to facilitate assembly. In the assembling process, after the first workpiece (or the second workpiece) is nested and assembled, the second workpiece (or the first workpiece) is buckled on the first workpiece (or the second workpiece), and the assembling is finished. Therefore, in order to ensure the assembly accuracy, it is necessary to level each layer of the sleeve of the first workpiece or the second workpiece during the nesting assembly process, and to ensure that the end surface of the multi-layer sleeve of the first workpiece or the second workpiece is in a preset state, for example, in a horizontal state. Here, the division of the first workpiece and the second workpiece is not limited to the case of assembling the two. Optionally, the splitting is performed on the principle of symmetrical splitting according to the shape of the nested structure workpiece. For example, the workpiece is divided into an upper workpiece and a lower workpiece in the vertical direction, or divided into a left workpiece and a right workpiece in the horizontal direction.

Optionally, as shown in fig. 3, a plurality of leveling circular lines are concentrically disposed on the tray body 11. For example, as shown in fig. 3, the leveling circular lines are a plurality of reference circles concentrically sleeved with each other. The end face of the multilayer sleeve suitable for the nested structure workpiece is of a circular open structure.

The number of leveling loops arranged on the tray body 11 is not limited and is determined according to actual conditions. For example, as shown in FIG. 2, 7 leveling loops are provided on the tray 11. From the outer side to the inner side, a first leveling loop 111, a second leveling loop 112, a third leveling loop 113, a fourth leveling loop 114, a fifth leveling loop 115, a sixth leveling loop 116 and a seventh leveling loop 117 are arranged in sequence; accordingly, the press column group includes a first press column group (including a plurality of first press columns 121) located on the first leveling loop line 111, a second press column group (including a plurality of second press columns 122) located on the second leveling loop line 112, a third press column group (including a plurality of third press columns 123) located on the third leveling loop line 113, a fourth press column group (including a plurality of fourth press columns 124) located on the fourth leveling loop line 114, a fifth press column group (including a plurality of fifth press columns 125) located on the fifth leveling loop line 115, a sixth press column group (including a plurality of sixth press columns 126) located on the sixth leveling loop line 116, and a seventh press column group (including a plurality of seventh press columns) located on the seventh leveling loop line 117.

In some embodiments, as shown in connection with FIG. 2, leveling platen 10 includes a plurality of sets of pressure columns having different lengths l of pressure columns 12 projecting from disk 11. In this embodiment, the length l of the pressing column 12 protruding from the tray body 11 is the length from the tray surface of the tray body 11 on the installation side of the pressing column 12 to the tail end of the pressing column 12, that is, the horizontal heights of the tail end surfaces of the pressing columns 12 of the plurality of pressing column groups are different during the leveling operation. Interference between the compression leg groups when different leveling operations are performed can be avoided. The length of the press studs 12 of the plurality of press stud sets is determined in accordance with the actual leveling requirements of the workpiece.

In some specific applications, in every two adjacent compression column groups, the length l of the compression column 12 of the compression column group positioned at the outer side protruding out of the disc body 11 _{Outer cover} Equal to or less than the length l of the compression columns 12 of the compression column group at the inner side protruding from the disc body 11 _{Inner part} . That is, at the time of leveling operation, the level of the distal end surfaces of the pressure columns 12 of the pressure column group located on the outer side (referred to as "outer level") is equal to or higher than the level of the distal end surfaces of the pressure columns 12 of the pressure column group located on the inner side (referred to as "inner level"). The nested structure workpiece is taken as an example for explanation, assembly is generally carried out in a nested mode from an outer layer to an inner layer in the assembly process of the nested structure workpiece, when leveling is carried out, an outer side pressing column group is firstly utilized to level an outer side suite, and then the assembled suite located on the inner side is leveled in sequence, so that the interference problem in the leveling of different suites can be avoided by setting the outer side horizontal height and the inner side horizontal height.

Optionally, in every two adjacent pressure column groups, the length l of the pressure column 12 of the pressure column group positioned at the outer side protruding out of the disc body 11 _{Outer cover} Equal to the length l of the press column 12 of the press column group at the inner side protruding from the plate body 11 _{Inner part} . I.e. bitThe horizontal height of the end surface of the end of the compression leg 12 of the compression leg group on the outer side is equal to the horizontal height of the end surface of the end of the compression leg 12 of the compression leg group on the inner side.

This embodiment is applicable to the condition of the terminal surface parallel and level of the multilayer external member of the first part work piece (or second part work piece) of nested structure work piece, and at this moment, when leveling the inlayer external member, can be simultaneously to being located all outer external members of outside and go on the synchronous levelling, guarantee the terminal surface parallel and level of multilayer external member. In addition, the embodiment is also suitable for the situation that the end surfaces of the multi-layer sleeve of the first workpiece (or the second workpiece) of the workpiece with the nested structure become higher from outside to inside, at this time, when the sleeve with the higher end surface positioned on the inner layer is calibrated, the height of the end surfaces of all the sleeves positioned on the outer layer is smaller than the height of the end surface of the currently leveled sleeve, and at this time, the end surface of the tail end of the compression leg 12 of the compression leg group positioned on the outer side does not contact with the end surface of the corresponding outer layer sleeve, and interference is not generated.

Alternatively, as shown in fig. 4 and 5, in each two adjacent pressure column groups, the length l of the pressure column 12 of the pressure column group located at the outer side protruding out of the tray body 11 _{Outer cover} The length l of the pressing column 12 protruding from the disc body 11 is less than that of the pressing column group positioned at the inner side _{Inner part} . That is, the level of the end surface of the end of the press stud 12 of the outer press stud group is higher than the level of the end surface of the end of the press stud 12 of the inner press stud group.

The embodiment is suitable for the condition that the end surfaces of the multilayer sleeve of the first part workpiece (or the second part workpiece) of the nested structure workpiece are level or the end surfaces of the sleeve from outside to inside are heightened, at the moment, when the inner layer sleeve is leveled, the end surface of the compression leg 12 of the compression leg group positioned at the outer side can not contact with the corresponding end surface of the outer layer sleeve, and interference can not be generated.

In addition, the present embodiment is also applicable to a case where the end surface of the multi-layer sleeve of the first part of the workpiece (or the second part of the workpiece) of the nested structure workpiece becomes lower from outside to inside, at this time, the height difference of the end surfaces of the pressing columns 12 in the two adjacent pressing column groups is equal to or greater than a first set value, and the first set value is the height difference of the end surfaces of the two adjacent layers of sleeves corresponding to the two adjacent pressing column groups. When the height difference of the end faces of the tail ends of the compression columns 12 in the two adjacent compression column groups is equal to a first set value, when the inner-layer sleeve is leveled, all outer-layer sleeves located on the outer side can be leveled synchronously, and the relative parallel and level of the end faces of the multi-layer sleeves are guaranteed. When the height difference of the end faces of the tail ends of the compression columns 12 in the two adjacent compression column groups is larger than a first set value, when the inner-layer sleeve is leveled, the end face of the tail end of the compression column 12 of the compression column group positioned on the outer side cannot contact with the end face of the corresponding outer-layer sleeve, and interference cannot be generated.

The operation of leveling two adjacent nests of nested configuration workpieces is described with reference to fig. 3-5, wherein only the leveling posts 12 located on the cross-sectional line are shown in the cross-sectional views of the leveling platens 10B-B in fig. 4 and 5 to more clearly illustrate the leveling process.

Of the two adjacent sets of nested workpieces, the first set 61 on the outer side corresponds to a first set of compression columns on the first leveling loop 111, and the first set of compression columns includes a plurality of first compression columns 121121; the second inside nesting component 62 corresponds to a second set of struts on the second leveling loop wire 112 that includes a plurality of second struts 122122. As shown in fig. 4, when the first bundle 61 is aligned by the first compression leg set, the inner bundle is not assembled, the inner space is empty, and the compression legs 12 of the remaining compression leg sets do not interfere with each other. As shown in fig. 5, when the second sleeve 62 is leveled by the second compression leg group, the length of the second compression leg 122 is greater than the length of the first compression leg 121, and when the second sleeve 62 is leveled, the first compression leg 121 located at the outer side does not contact the first sleeve 61, so that the second sleeve 62 is leveled, and interference with the first sleeve 61 is avoided. Of course, when the second sleeve 62 is leveled, the first pressing column 121 located at the outer side is also adapted to contact the first sleeve 61, so that the first sleeve 61 and the second sleeve 62 are leveled at the same time, the relative parallelism of the two sleeves is maintained, and the parallelism precision between the sleeves is improved.

In the embodiment of the present disclosure, a plurality of leveling loops are disposed on the tray body 11, and the distance between two adjacent leveling loops is not limited, and is determined according to the relative position of the corresponding end surface to be leveled. For example, for a nested structure workpiece, the distance between the end faces to be leveled of the two corresponding external members is determined. When the number of the leveling loops is equal to or greater than 3, and the number of the intervals between every two leveling loops is equal to or greater than 2, the sizes of the intervals may be the same, may be all different, may also be partially the same, partially different, and is not limited.

In some embodiments, as shown in fig. 3 and 4, the compression columns 12 of the compression column sets on two adjacent leveling loops are staggered. As shown in fig. 3, taking the leveling ring lines as circles, the radial lines of the compression legs 12 disposed on two adjacent leveling ring lines do not coincide. Set up like this, on the one hand can avoid producing the problem of interfering between the compression leg 12 at the interval of two adjacent levelling loop lines is little, and on the other hand can also avoid offering the problem that two adjacent nearer mounting holes lead to disk body 11 intensity to reduce on same radial line.

In the embodiment of the disclosure, a plurality of compression columns 12 are arranged on each leveling loop, and the plurality of compression columns 12 are distributed on the leveling loops without limitation, so that the leveling loop can apply balanced pressure to the leveling end face to be set as a principle, and the leveling effect is ensured without tilting one side of the leveling sleeve.

Alternatively, the plurality of pressing cylinders 12 are symmetrically disposed on the leveling loop line with the center of the leveling loop line as a symmetrical point. That is, the number of the compression columns 12 in each compression column group is at least 2, and the center of the leveling loop line is used as symmetrical point symmetry to set, so that the uniform downward pressure formed on the end face to be leveled is ensured, the problem of one side tilting of the workpiece caused by uneven downward pressure is avoided, and the leveling effect is ensured.

In the embodiment of the present disclosure, in each pressing column group, the number of the pressing columns 12 is not less than 2. Alternatively, the number of the pressing pillars 12 is not less than 3. Alternatively, the number of the pressing columns 12 is not less than 4. The number of compression legs 12 is in principle not limited to its upper limit value, the greater the number, the greater the contact points with the end surface to be leveled, it being understood that when the number of compression legs 12 is sufficiently high, they are arranged in close proximity, constituting an annular compression ring.

In some embodiments, the number of compression legs 12 in each compression leg set is 2 to 10. The specific number of compression legs 12 is determined by the shape and size of the leveling circuit.

Alternatively, the number of the pillars 12 is 2 to 8.

Alternatively, the number of the pillars 12 is 3 to 6. In this embodiment, the number of the compression legs 12 may be 3, 4, 5, or 6.

Alternatively, the number of the compression legs 12 is 4.

In the embodiment of the disclosure, when the pressing and leveling are performed, the end face of the end of the pressing column 12 contacts and presses the end face to be leveled, so that the end face of the pressing column 12 is set to be in a shape matched with the contact surface of the end face to be leveled, the contact area is increased, and the stability of the pressing is improved.

Alternatively, the end face of the end of the compression leg 12 is flat. In this embodiment, when the pressing pillars 12 are disposed on the tray body 11 and the end surfaces of the pressing pillars are horizontal, the leveling surfaces of the pressing pillars are flat, which is suitable for the situation that the end surfaces to be leveled are flat. When the pressure pillars 12 are disposed on the tray body 11 and the end faces of the end portions of the pressure pillars are inclined planes, the leveling surfaces of the assembled pressure pillars are pyramid surfaces, which is suitable for the situation that the end faces to be leveled are prism surfaces.

Optionally, the end surface of the end of the compression leg 12 is cambered. The leveling surface of the compression leg set consisting of the compression legs of the embodiment is a curved surface, and is suitable for the condition that the end surface to be leveled is a curved surface.

In the embodiment of the present disclosure, the leveling surfaces constructed by the end surfaces of the tail ends of the plurality of press pillars 12 of the press pillar group are adapted to the end surfaces to be leveled of the workpiece, where the end surfaces to be leveled may be located in the same horizontal plane or may be located in different horizontal planes. Therefore, a plurality of compression columns 12 of the same compression column group can be adapted according to the shape and the height state of the end surface to be leveled, so that the end surfaces of the plurality of compression columns 12 form an adapted leveling surface, the end surface parts which are not on the same horizontal plane can receive the same leveling pressure when leveling, and accurate leveling is achieved. That is, the horizontal heights of the ends of the compression columns 12 of the plurality of compression columns 12 of the compression column group are the same or different. The setting is carried out according to the actual situation.

In some embodiments, the length l of the plurality of compression columns 12 protruding from the tray 11 is the same in the same compression column group. Optionally, when the end face of the end of the compression leg 12 is a plane, the constructed leveling plane is a plane, and the method is suitable for the case that the end face to be leveled is a plane.

In some embodiments, the length l of the plurality of pressing columns 12 protruding from the tray 11 is different in the same pressing column group. Optionally, when the end face of the end of the compression leg 12 is a plane, the constructed correcting plane is a non-plane, which is suitable for the case that the end face to be leveled is a non-plane, for example, for the case that the end face to be leveled is a step face.

In some embodiments, the plate 11 has a plurality of fixing holes along the leveling ring for fixing the pressing pillars 12. The opening position of the fixing hole is determined according to the arrangement mode of the compression leg 12. It will be appreciated that the fixed end of the compression leg 12 is provided with a spigot 1203. The plug 1203 is fixed and inserted into the fixing hole of the tray 11.

In the embodiment of the present disclosure, the specific structural form of the disc body 11 is not limited, and the downward pressure can be transmitted to the pressing column 12 in a balanced manner in the vertical downward pressing leveling process. In some embodiments, the tray 11 is flat. Alternatively, the tray body 11 has a circular flat plate shape.

In some embodiments, weight-reducing structures are provided on the tray body 11. To reduce the influence of the gravity of the tray 11 itself on the downforce. Optionally, the weight-reducing structure includes a plurality of weight-reducing holes 110, and the weight-reducing holes 110 penetrate through the thickness direction of the tray body 11 and are offset from the arrangement position of the compression leg 12.

In the disclosed embodiment, the shape of the tray body 11 may be identical to the shape of the leveling loop. For example, the shape of the tray body 11 is circular.
