Description

Technical Field

[0001] This utility model relates to the technical field of insulation box processing equipment, specifically to an insulation box main layer workpiece positioning device. Background Technology

[0002] The cargo hold of a liquefied natural gas (LNG) carrier typically consists of a main layer and a secondary layer. The main layer, located closer to the inner part of the cargo hold, directly withstands the low temperatures and bears the main insulation load. The main layer is usually constructed from a main insulation box. One or more edges of this box utilize a main layer component with multiple wedges to allow for a tight fit between multiple main insulation boxes. Manufacturing this component involves bonding multiple wooden wedges to a long strip of plywood and securing them with nails. To ensure a tight fit between the multiple main insulation boxes and to guarantee the insulation performance of the main layer, high dimensional accuracy is required for the main layer component. Consequently, precise positioning of the plywood and wedges is necessary during its manufacturing.

[0003] Taking the main layer workpiece of a certain type of main layer insulation box as an example, a wedge needs to be fixed at each of the four corners of the plywood. There are two different sizes of wedges, and one side of each wedge must be aligned with one side of the plywood. A predetermined gap needs to be maintained between one end of the wedge and one end of the plywood. The gaps between the two types of wedges are different. Currently, there is no automatic positioning device that can automatically complete the positioning between the plywood and multiple wedges of different sizes. Currently, in manufacturing this type of main layer workpiece, positioning is mainly achieved manually using relatively simple auxiliary tools. For example, thick wooden strips are used to press down one side of the wedge and one side of the plywood, and the sides are manually aligned. The gaps at the ends are then checked with a ruler and manually adjusted. After the positioning is correct, the wedges are driven in. It is evident that the current processing efficiency is low. Due to the large size of the plywood, the operation is very inconvenient, and it is also difficult to guarantee high-precision positioning between the plywood and the wedges. Utility Model Content

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the main layer workpiece positioning device of the insulation box of this utility model in detail with reference to the embodiments and accompanying drawings.

[0028] Example 1

[0029] This embodiment provides a positioning device for the main layer workpiece of an insulation box, used in conjunction with a nailing device to process and manufacture the main layer workpiece of the insulation box. The insulation box can be divided into a main layer insulation box and a secondary layer insulation box. The main layer insulation box is the insulation component closer to the inner side of the LNG cargo tank, directly bearing the low temperature and the main thermal insulation load. The two sides of the main layer insulation box use a main layer workpiece with wedges to allow multiple main layer insulation boxes to be spliced ​​together. This embodiment provides a device for positioning the components of this main layer workpiece.

[0030] To better illustrate the structure of the main layer workpiece positioning device of the insulation box in this embodiment, the structure of the main layer workpiece will be briefly described below.

[0031] Figure 9 This is a schematic diagram of the structure of the main layer workpiece of the insulation box in the prior art.

[0032] like Figure 9As shown, the main layer workpiece 9 includes a plate 93, two first wedges 91, and two second wedges 92. The plate 93 is a rectangular wooden board with a row of through holes in the middle and several notches on both sides in the width direction. The wedges are cuboid wooden blocks, significantly shorter and narrower than the plate 93, but thicker. The length of the second wedges 92 is greater than the length of the first wedges 91. The four wedges are fixed to the same surface of the plate 93. The two first wedges 91 are fixed to two corners on one side of the plate 93 in the width direction, and the two second wedges 92 are fixed to two corners on the other side of the plate 93 in the width direction. The length directions of the first wedges 91 and second wedges 92 are aligned with the length direction of the plate 93. One side of each wedge in the width direction is aligned with one side of the plate 93 in the width direction, and a predetermined distance exists between one side of each wedge in the length direction and one end of the plate 93 in the length direction.

[0033] To ensure the proper splicing of multiple main insulation boxes and to guarantee the insulation performance of the liquid cargo tank, high precision is required in the dimensions and relative positions of plate 93, the first wedge 91, and the second wedge 92. Therefore, accurate positioning of their relative positions is necessary during processing.

[0034] The structure and function of the device in this embodiment will be specifically explained below in conjunction with the structure of the main layer workpiece 9 described above.

[0035] Figure 1 This is a perspective view of the workpiece positioning device for the main layer of the insulation box in this embodiment. Figure 2 This is a top view of the workpiece positioning device for the main layer of the insulation box in this embodiment.

[0036] like Figure 1 and Figure 2 As shown, the main layer workpiece positioning device 100 of the insulation box includes a positioning platform 10, a first pressing unit 30, a second pressing unit 40, a detection unit 50, and an electrical control unit 60.

[0037] The positioning platform 10 includes a base plate 11 that is roughly in the shape of an I-beam, an extension plate 12 fixed to one side of the base plate, multiple fixing posts at the four corners of the base plate 11, multiple pull rings 14 near the four corners of the base plate 11, multiple uprights fixed to the base plate 11, and a bearing plate 15 supported by the multiple uprights.

[0038] The extension plate 12 is roughly rectangular and is fixed to one edge of the base plate 11 in the width direction for mounting the electronic control unit 60.

[0039] The support plate 15 is generally rectangular and is positioned above the base plate 11, parallel to it. The base plate 11 and the support plate 15 support and mount components and have multiple mounting holes. The support plate 15 also has one main clearance hole 151 and two secondary clearance holes 152 on each side, all of which are rounded square through holes used to allow space for movable components. The main clearance hole 151 is larger, while the two secondary clearance holes 152 are relatively smaller, formed on one side of the main clearance hole 151 and closer to the center of the support plate 15. Furthermore, shallow mounting grooves are formed at the edges of both sides of the main clearance hole 151.

[0040] Figure 3 This is a schematic diagram showing the layout of the first and second clamping units in this embodiment. Figure 3 The diagram schematically illustrates the distribution and correspondence of multiple pressure blocks and cylinders on the support plate, where each pressure block is represented by a square, each cylinder by a circle, and the correspondence is represented by connecting lines.

[0041] like Figures 1 to 3 As shown, the first clamping unit 30 and the second clamping unit 40 include multiple clamping blocks, each of which is a long strip-shaped block with its length direction horizontal. One side of each block is a long strip-shaped clamping surface, which is a vertical surface used to clamp one side of the plate and / or wedge, thereby positioning it. Some of the clamping blocks are fixed, while others are movable. The movable clamping blocks are equipped with corresponding drive components, all of which are cylinders. Each clamping block has multiple mounting holes extending along its thickness direction, through which it is fixed to a block-shaped connector, an L-shaped connector, or a cylinder push plate.

[0042] Furthermore, since the wedges are coated with adhesive before being placed in the device for positioning, adhesive may overflow during the positioning process. To reduce the impact of adhesive adhesion on the device, each pressure block is made of stainless steel, so even if a small amount of adhesive adheres to it, it can be easily removed. Several cylinders are also covered with stainless steel plate-shaped protective parts, which at least partially shield the upper surface of the cylinder and the piston rod to prevent adhesive adhesion from affecting the cylinder's operation.

[0043] The first pressing unit 30 and the second pressing unit 40 are respectively disposed at both ends of the bearing plate 15. The first pressing unit 30 is used to press a set of wedges (in this embodiment, a first wedge 91 and a second wedge 92), and the second pressing unit 40 is used to press another set of wedges. The two pressing units are also used to cooperate with each other to press the plate 93 stacked on the two sets of wedges, thereby positioning the two sets of wedges and the plate 93 in their length and width directions.

[0044] Figure 4 yes Figure 2 An enlarged view of the area inside frame A, and Figure 4 The support plate is omitted to show the structure beneath it.

[0045] like Figure 3 and Figure 4 As shown, the first clamping unit 30 includes a first length-direction clamping mechanism 31, a first spacing control mechanism 32, and a first width-direction clamping mechanism 33. The first length-direction clamping mechanism 311 is used to clamp a set of wedges in the x-direction (i.e., the length direction of these wedges). The first width-direction clamping mechanism 33 cooperates with the first spacing control mechanism 32 to clamp the two wedges in the y-direction (i.e., the width direction of these two wedges) and control their spacing.

[0046] The first length-direction pressing mechanism 31 includes a first fixed pressing block F1, a second fixed pressing block F2, a first movable pressing block M1, a second movable pressing block M2, and a first driving assembly (first length-direction driving assembly).

[0047] The first fixed pressure block F1 is cuboid in shape and is fixed to the support plate 15 at one end along its length by a block-shaped connector. Its pressing surface is perpendicular to the x-direction. The first movable pressure block M1 is also cuboid in shape and is positioned corresponding to the first fixed pressure block F1 along the x-direction. Its pressing surface is perpendicular to the x-direction and faces the pressing surface of the first fixed pressure block F1. Both are used to cooperate and press the two sides of the first wedge block 91 along its length.

[0048] The second fixed pressure block F2 is cuboid in shape and is fixed to the support plate 15 by a block-shaped connector. It is located at one end of the support plate 15 along its length and is closer to one edge of the support plate 15 along its length than the first fixed pressure block F1. Its pressing surface is perpendicular to the x-direction. The second movable pressure block M2 is also cuboid in shape and is positioned corresponding to the second fixed pressure block F2 in the x-direction. Its pressing surface is perpendicular to the x-direction and faces the pressing surface of the second fixed pressure block F2.

[0049] The first drive assembly includes a first cylinder C1, a first slide assembly, and a first limiting member. The first cylinder C1 is horizontally positioned, with its piston rod extending along the x-direction. The first slide assembly includes two L-shaped connectors, two guide rails extending along the x-direction, and a horizontal first slide plate T1 movably mounted on the two guide rails. The end of the piston rod of the first cylinder C1 is fixed to a connecting plate. A first movable pressure block M1 and a second movable pressure block M2 are respectively fixed to the first slide plate T1 via L-shaped connectors. The L-shaped connectors extend through a secondary clearance hole 152 on the support plate 15 to below the support plate 15, and the connecting plate is located below the support plate 15. Therefore, the first cylinder C1 can simultaneously drive the first movable pressure block M1 and the second movable pressure block M2 to move along the x-direction. Two first limiting members are respectively set on both ends of the connecting plate, and are located on both sides of the connecting plate along with the first cylinder C1. When the slide plate T1 moves into place, it will abut against the two first limiting members, and the L-shaped connecting member can only move within the range of the secondary clearance hole 152, thereby limiting the displacement distance of the two movable pressure blocks.

[0050] The first spacing control mechanism 32 includes a first spacing control pressure block A1, a second spacing control pressure block A2, and a second drive assembly (spacing control drive assembly).

[0051] The first spacing control block A1 and the second spacing control block A2 are both cuboid in shape and located above a main clearance hole 151 on the bearing plate 15. Their pressing surfaces are perpendicular to the y-direction and positioned opposite each other. The second drive assembly includes a second cylinder C2 and a second slide assembly. The second slide assembly includes an L-shaped connector, a plate-shaped connector, two guide rails extending along the y-direction, and two second slide plates T2 movably mounted on the guide rails. The first spacing control block A1 is fixed to one of the second slide plates T2 via the L-shaped connector, and the second spacing control block A2 is fixed to the other second slide plate T2 via the plate-shaped connector. The L-shaped connector also has a connecting groove at its corner. The second cylinder C2 is horizontally positioned, with its piston rod extending along the y-direction. The bottom of the second cylinder C2 is fixed to the plate-shaped connector, and the piston rod is fitted into the connecting groove of the L-shaped connector. Therefore, the second cylinder C2 can drive the two spacing control blocks closer to or further apart.

[0052] The first width-direction pressing mechanism 33 includes a third fixed pressing block F3, a third movable pressing block M3, and a third driving assembly (width-direction driving assembly).

[0053] The third fixed pressure block F3 is trapezoidal (its cross-section along its length is trapezoidal), forming an inclined surface above its pressing surface. The third fixed pressure block F3 is fixed to the support plate 15 by a block-shaped connector and is located on one side of the second fixed pressure block F2 and the second movable pressure block M2, with its pressing surface perpendicular to the y-direction. The third movable pressure block M3 is positioned corresponding to the third fixed pressure block F3 in the y-direction, with its pressing surface perpendicular to the y-direction and facing the pressing surface of the third fixed pressure block F3. The third drive assembly includes a larger third cylinder C3, which is horizontally fixed to one edge of the base plate 11. Its piston rod extends along the y-direction and is located at a height above the support plate 15. The third movable pressure block M3 is fixed to the piston rod of the third cylinder C3.

[0054] Furthermore, the first spacing control block A1 and the second spacing control block A2 are disposed between the third fixed block F3 and the third movable block M3. In the y-direction, the third fixed block F3 is also disposed correspondingly to the first spacing control block A1, with their pressing surfaces facing each other; the third movable block M3 is also disposed correspondingly to the second spacing control block A2, with their pressing surfaces facing each other.

[0055] Figure 5 yes Figure 2 An enlarged view of the area inside frame B, and Figure 5 The supporting plate is omitted in the text.

[0056] like Figure 3 and Figure 5 As shown, the second clamping unit 40 includes a second length clamping mechanism 41, a second spacing control mechanism 42, and a second width clamping mechanism 43. The second length clamping mechanism 41 is used to clamp another set of wedges in the x-direction, and the second width clamping mechanism 43 and the second spacing control mechanism 42 are used to clamp the two wedges in the y-direction and control their spacing.

[0057] The second length-direction clamping mechanism 41 includes a fifth movable clamping block M5, a sixth movable clamping block M6, a seventh movable clamping block M7, an eighth movable clamping block M8, a fifth drive assembly, and a seventh drive assembly. These movable clamping blocks are all cuboid in shape, and their clamping surfaces are perpendicular to the x-direction. The fifth movable clamping block M5 and the sixth movable clamping block M6 are located near the center of the support plate 15, while the seventh movable clamping block M7 and the eighth movable clamping block M8 are located at the opposite edge of the support plate 15 along its length. In the x-direction, the fifth movable clamping block M5 and the seventh movable clamping block M7 are correspondingly positioned with their clamping surfaces facing each other, used to clamp the two sides of the first wedge block 91 along its length; the sixth movable clamping block M6 and the eighth movable clamping block M8 are correspondingly positioned with their clamping surfaces facing each other, used to clamp the two sides of the second wedge block 92 along its length.

[0058] The fifth drive assembly includes a fifth cylinder C5 and a slide assembly, and its structure is basically the same as that of the first drive assembly. It is used to simultaneously drive the fifth movable pressure block M5 and the sixth movable pressure block M6 to move along the x-direction. The seventh drive assembly includes a seventh cylinder C7, a slide assembly, and a limiting member. The slide assembly includes two guide rails extending along the x-direction, a seventh slide plate T7 movably mounted on the two guide rails, and a T-shaped connector L7 fixed to the seventh slide plate T7. The seventh cylinder C7 is horizontally fixed to the base plate 11, and its piston rod extends along the x-direction and is fixed to the slide plate T7. The seventh movable pressure block M7 and the eighth movable pressure block M8 are respectively fixed to the upper ends of the T-shaped connector L7, and the width of the seventh movable pressure block M7 in the x-direction is greater than the width of the eighth movable pressure block M8, so that its pressing surface is closer to the center of the bearing plate 15 than the pressing surface of the eighth movable pressure block M8.

[0059] The second spacing control mechanism 42 includes a third spacing control block A3, a fourth spacing control block A4, and a sixth drive assembly. The sixth drive assembly includes a sixth cylinder C6, a slide assembly with double slides and an L-shaped connector. Its structure is basically the same as that of the first spacing control mechanism 32.

[0060] The second width-direction pressing mechanism 43 includes a fourth fixed pressing block F4, a fourth movable pressing block M4, and a fourth drive assembly, the fourth drive assembly including a fourth cylinder C4. Its structure is basically the same as that of the first width-direction pressing mechanism 33.

[0061] In addition, the first clamping unit 30 also includes a ninth fixed clamping block F9 (fixed clamping block for plate parts), and the second clamping unit 40 also includes a ninth movable clamping block M9 (movable clamping block for plate parts), which are correspondingly arranged in the x-direction, with their clamping surfaces facing each other and perpendicular to the x-direction, for clamping the two sides of the plate part 93 in the length direction. The ninth fixed clamping block F9 is trapezoidal and fixed at one edge of the bearing plate 15 in the length direction, and is closer to the edge of the bearing plate 15 in the length direction than the second fixed clamping block F2. The ninth movable clamping block M9 is trapezoidal and fixed at the upper middle part of the T-shaped connecting plate L7, and is located between the seventh movable clamping block M7 and the eighth movable clamping block M8.

[0062] The ninth fixed pressure block F9, the ninth movable pressure block M9, the third movable pressure block M3, the third fixed pressure block F3, the fourth movable pressure block M4, and the fourth fixed pressure block F4 are distributed along the edge of the bearing plate 15. Their distribution corresponds to the outer periphery shape of the plate 93. They are used to simultaneously press the sides of the plate 93 and the wedge. The height of the pressing surface of these pressure blocks matches the stacking height of the horizontally placed plate 93 and the wedge.

[0063] That is, among the multiple pressure blocks used to press the wedge in the y-direction, four of them are also used to press the plate 93 in the y-direction, and the ninth movable pressure block M9 used to press the plate 93 in the x-direction reuses the drive assembly for pressing the wedge in the x-direction. It can be seen that, based on the characteristics of the relative positions of the plate and the two types of wedges, the pressing unit in this embodiment has many reused structures, simplifying its structure and reducing the number of cylinders used.

[0064] The detection unit 50 is used to detect whether the plate and wedge have been placed in place, thus realizing automated control. The detection unit 50 includes at least a plate detection sensor 51 and two wedge detection sensors 52, both of which are photoelectric sensors. The support plate 15 also has a detection clearance hole 153 in the middle. The plate detection sensor 51 is fixed to the lower surface of the support plate 15 and detects whether a plate 93 is placed at a predetermined distance above the support plate 15 through the detection clearance hole 153. One wedge detection sensor 52 is fixed to one side edge of the support plate 15 and is located next to the third fixed pressure block F3. It detects whether a second wedge 92 is placed between these pressure blocks through the gap between the third fixed pressure block F3 and the second movable pressure block M2. The other wedge detection sensor 52 is fixed to one side edge of the support plate 15 and is located next to the fourth fixed pressure block F4. It detects whether another second wedge 92 is placed between these pressure blocks through the gap between the fourth fixed pressure block F4 and the eighth movable pressure block M8.

[0065] In an alternative, the detection unit 50 may also include more sensors, such as four wedge detection sensors 52, each used to detect whether the four wedges are in place.

[0066] The electronic control unit 60 includes a control circuit board and multiple solenoid valves, which are used to control multiple cylinders according to the detection results of the detection unit 50 and the predetermined positioning program. The positioning process is started when the wedge and plate are detected to be in place, and the movable pressure blocks are controlled to move in a predetermined order.

[0067] Figure 6 This is a three-dimensional representation of the working state of the main layer workpiece positioning device of the insulation box in this embodiment. Figure 1 This shows the situation where the four wedges are clamped and positioned. Figure 7 This is a three-dimensional representation of the working state of the main layer workpiece positioning device of the insulation box in this embodiment. Figure 2 , showing in Figure 6 On the basis of this, the positioning plate is pressed down simultaneously.

[0068] like Figure 6 and Figure 7As shown, before positioning begins, the piston rods of each cylinder retract, and the distance between the corresponding pressure blocks is relatively large, allowing wedges and plates to be inserted. On one side, a first wedge 91 coated with glue is placed in the space between the first fixed pressure block F1, the first movable pressure block M1, the third movable pressure block M3, and the first spacing control pressure block A1. A second wedge 92 coated with glue is placed in the space between the second fixed pressure block F2, the second movable pressure block M2, the second spacing control pressure block A2, and the third fixed pressure block F3. On the other side, similarly, two wedges coated with glue are placed in the spaces between the multiple pressure blocks. Then, a plate 93 is placed above the multiple wedges in the space between the ninth fixed pressure block F9, the ninth movable pressure block M9, the third movable pressure block M3, the fourth movable pressure block M4, the third fixed pressure block F3, and the fourth fixed pressure block F4.

[0069] Then, the main layer workpiece positioning device 10 of the insulation box can be activated. Under the control of the electronic control unit 60, the first pressing unit 30 presses one set of wedges in two directions and controls their spacing; the second pressing unit 40 presses another set of wedges in two directions and controls their spacing; at the same time, the first pressing unit 30 and the second pressing unit 40 cooperate to press the upper plate 93 in two directions, thereby realizing the positioning of the plate 93 and multiple wedges, so that it has an accurate relative position.

[0070] Functions and effects of Example 1

[0071] The insulation box main layer workpiece positioning device provided in this embodiment includes a positioning table, a first clamping unit, and a second clamping unit. It can place multiple wedges, stack plates on top of the wedges, and clamp the wedges and plates in their length and width directions, thereby achieving accurate positioning of the relative positions of the plates and wedges. After positioning, a nailing device can be used to fix the plates and wedges, thus forming the insulation box main layer workpiece. Manual positioning using tools is no longer required, significantly improving processing efficiency and providing more accurate positioning. Furthermore, since the first and second clamping units each position a set of wedges, and simultaneously cooperate to position the plates stacked on top, the device reuses part of the clamping unit structure based on the structural and relative position characteristics of the plates and wedges, making the overall structure of the clamping unit more streamlined.

[0072] In this embodiment, both the first and second clamping units have a length-direction clamping mechanism, a width-direction clamping mechanism, and a spacing control mechanism. This not only allows for the clamping of multiple wedges in their length and width directions but also enables precise control of the spacing between two wedges in the same group. Furthermore, based on the relative positions of the plate and the multiple wedges, multiple pressure blocks distributed along the edge of the supporting plate simultaneously clamp one side of both the plate and the wedges. One movable pressure block for clamping the plate in the length direction shares a drive assembly (one cylinder) with two movable pressure blocks for clamping a group of wedges. Therefore, the clamping unit contains many reused structures, making the overall structure more streamlined. In this embodiment, there are thirteen movable pressure blocks and only seven cylinders. Moreover, due to the small size of the wedges and the relatively low distance between two wedges in a group, the space available for arranging clamping structures around them is limited. This design allows for clamping of each wedge in both the length and width directions within a limited space.

[0073] Furthermore, in the second clamping unit, the clamping blocks used to clamp the two sides of the wedge in the length direction are all movable clamping blocks, thereby enabling simultaneous positioning of the plate and the wedge in the length direction, resulting in higher positioning efficiency. Similarly, in both clamping units, the width clamping mechanism includes a fixed clamping block and a movable clamping block, and the spacing control mechanism includes a pair of spacing control clamping blocks disposed between these two clamping blocks. These blocks can move closer or further apart under the drive of a cylinder, thereby enabling simultaneous control of the spacing between the two wedges in a set and alignment of one side of the wedge with one side of the plate, resulting in higher positioning efficiency.

[0074] Furthermore, among the multiple pressure blocks, the pressure blocks used only for pressing the wedges are all rectangular, while the pressure blocks used for pressing both the wedges and the plates are all trapezoidal strips. Therefore, only two types of standard parts need to be processed as pressure blocks, which can reduce the cost of the device and make it convenient and quick to replace the pressure blocks when they are worn.

[0075] Furthermore, the pressure blocks are all made of stainless steel, and some cylinders are also covered with stainless steel protective parts. This prevents glue from overflowing from the wedges and adhering to the pressure blocks or cylinders, thus avoiding any impact on the positioning process. Even if a small amount of glue adheres to the pressure blocks, it can be removed relatively easily.

[0076] Example 2

[0077] This embodiment provides a workpiece positioning device for the main layer of an insulation box. In this embodiment, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0078] Figure 8 This is a perspective view of the workpiece positioning device for the main layer of the insulation box in this embodiment.

[0079] like Figure 8 As shown, compared with Embodiment 1, the difference lies in that, in the main layer workpiece positioning device 10 of the insulation box in this embodiment, the positioning platform 11 includes multiple base plates 11 and two support plates 15. The first pressing unit 30 and the second pressing unit 40 are respectively disposed on the two support plates 15, and the two support plates 15 are correspondingly installed on the two base plates 11. Furthermore, the device also has a distance adjustment unit 70, in which one support plate 15 is fixed on the base plate 11, and the other support plate 15 is disposed on the base plate 11 through the distance adjustment unit 70, and can move along the length direction of the base plate 11, thereby adjusting the distance between the two support plates 15, that is, adjusting the distance between the two pressing units, thereby pressing the plate 93 in its length direction, and applicable to plates 93 of different lengths. Correspondingly, the second pressing unit 40 of this embodiment does not have a seventh driving assembly; the seventh movable pressing block M7, the eighth movable pressing block M8, and the ninth movable pressing block M9 are fixed to one edge of the movable support plate 15.

[0080] The distance adjustment unit 70 can adopt a horizontal moving structure as used in the prior art. In this embodiment, it includes two guide rails 71, a lead screw 72, a handwheel 73, and a locking mechanism 74, all mounted on a base. A support plate 15 is movably mounted on the two guide rails 71 via a slider and is fixed to the nut seat of the lead screw 72. The lead screw 72 can be locked or unlocked using the locking mechanism 74. In the unlocked state, the handwheel 73 can be turned to rotate the lead screw 72, thereby moving the support plate 15.

[0081] In this embodiment, the other structures are similar to those in Embodiment 1, especially the structure of the clamping unit, which is basically the same as that in Embodiment 1, so it will not be described again.

[0082] also, Figure 6 and Figure 7 The document also illustrates a nailing device and a nailing auxiliary device that can be used in conjunction with the main layer workpiece positioning device 10 of the insulation box. The nailing auxiliary device includes two auxiliary plates, each with multiple rectangular through holes for auxiliary nailing positioning according to the required nailing positions. After positioning is completed by the main layer workpiece positioning device 10 of the insulation box, the nailing auxiliary device can be set on the two clamping units, and nailing can be performed by the nailing device to fix the wedge to the plate. The main layer workpiece positioning device 10 of the insulation box in Embodiment 1 can also work in the same way with such a nailing device and nailing auxiliary device.

[0083] Functions and effects of Example 2

[0084] Based on the function and effect of Embodiment 1, the positioning device for the main layer workpiece of the insulation box provided in this embodiment includes two bearing plates and a distance adjustment unit. Two pressing units are respectively provided on the two bearing plates, and one of the bearing plates can be moved by the distance adjustment unit. Therefore, the interval distance between the first pressing unit and the second pressing unit can be adjusted, which can also realize the pressing and positioning of the plate in its length direction. This also makes the positioning device for the main layer workpiece of the insulation box applicable to a variety of main layer workpieces of different lengths, improving the versatility of the device.
