Description

Technical Field

[0001] The utility model relates to the technical field of tools, in particular to a wood-substitute adhesive fixing and clamping tool. Background Art

[0002] During the automobile research and development process, the whole vehicle model parts are processed using substitute wood materials. Since the substitute wood materials are of standard specifications and sizes, most workpiece sizes are larger than the substitute wood specifications, such as door panels, center armrests, dashboards, fenders, wheels, etc. The cut substitute wood needs to be bonded with substitute wood glue. Due to the poor fluidity of substitute wood glue, there will be some parts without glue each time bonding, causing the substitute wood to fall off and break at the bonding point during the workpiece milling process. In some parts, there is more substitute wood glue, which causes waste. The substitute wood bonding technology requires the glue thickness to be 0.2mm. If the glue is too thick, the shrinkage of the substitute wood will be poor.

[0003] During the gluing process, the substitute wood material is usually bonded using its own weight, or pressed with a heavy object, or clamped with an F-shaped iron clamp. However, bonding with the substitute wood material itself or pressing with a heavy object will cause sliding displacement, and the substitute wood glue is thick, which wastes the substitute wood glue. The tightening force of the F-shaped iron clamp to clamp the substitute wood is not enough, the bonding effect is not good, which affects the material processing, and the handle is often damaged during the tightening process, and there is no repair value after damage; the contact surface between the F-shaped clamp and the substitute wood is small, and the substitute wood bonding has a good clamping effect only at the contact position of the clamp. The substitute wood glue is thick away from the contact area of ​​the clamp, and there is warping and deformation in other positions; the clamp can only play a clamping role and has no function to prevent the substitute wood from sliding, so the substitute wood will still slide.

[0004] The sliding displacement of the substitute wood is more than 5mm. This displacement affects the processing system, causing the knife to become stuck during processing in places where the blank size is large, and the missing meat parts will cause local meat missing in the workpiece. The missing meat parts also need to be repaired in the equipment, affecting the completion progress of the entire project and the completion time of subsequent grinding and assembly.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0026] In the description of this utility model, it should be noted that the term "including" and its variations represent an open-ended inclusion, i.e., "including but not limited to." The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0027] The utility model provides a wood substitute adhesive fixing clamping tool, comprising a clamping unit 100, such as Figure 1 As shown, the clamping unit 100 includes a base 101 and two support screws 102, and the bottom ends of the two support screws 102 are slidably connected to the base 101. Preferably, a through slide 1011 can be provided on the upper surface of the base 101, and a slider 1021 adapted to the slide 1011 can be provided at the bottom end of the support screw 102, so that the support screw 102 can slide along the slide 1011, and the distance between the two support screws 102 can be adjusted to accommodate different sizes of wood blanks 200. A connecting plate 103 is sleeved on each of the support screws 102, and one end of the connecting plate 103 is threadedly connected to a first clamping screw 104 arranged parallel to the support screw 102. A first nut 106 is threadedly connected to the support screw 102, and the first nut 106 is located above the connecting plate 103. After the two substitute wood blanks 200 are bonded using the substitute wood glue 300, the first pressing screw 104 is rotated downward. The first pressing screw 104 presses the upper substitute wood blank 200 vertically downward, so that the two substitute wood blanks 200 are firmly bonded and prevents the substitute wood blank 200 from sliding during the curing process of the substitute wood glue 300. When the first pressing screw 104 is rotated into place, the first nut 106 is tightened so that the first nut 106 fits the connecting plate 103, which can fix the connecting plate 103 between the first nut 106 and the substitute wood blank 200, preventing the connecting plate 103 from moving upward, making the height of the first pressing screw 104 stable, thereby keeping the pressing force of the first pressing screw 104 stable and ensuring the thickness of the substitute wood glue 300 accurate.

[0028] In one embodiment, a first pressing plate 105 is provided at the bottom of the first pressing screw 104, and the first pressing plate 105 is connected to the first pressing screw 104 via a first ball nut; alternatively, the first pressing plate 105 is provided with a first blind threaded hole, and the first pressing screw 104 is threadedly connected to the first blind threaded hole. When the first pressing screw 104 rotates and moves downward, it moves the first pressing plate 105 downward, causing the first pressing plate 105 to contact the upper surface of the substitute wood blank 200. When the first pressing screw 104 continues to rotate, the first pressing plate 105 and the first pressing screw 104 form a screw transmission, and the first pressing plate 105 does not rotate around the first pressing screw 104. The first pressing screw 104 drives the first pressing plate 105 to move only vertically downward, causing the first pressing plate 105 to press the substitute wood blank 200 vertically downward, applying vertical pressure to the substitute wood blank 200 to prevent the substitute wood blank 200 from sliding. By pressing the substitute wood blank 200 through the first pressing plate 105 , it is also possible to prevent the first pressing screw 104 from directly pressing the substitute wood blank 200 and rotating and pressing to produce a deep mark on the surface of the substitute wood blank 200 .

[0029] In one embodiment, the clamping unit further includes a crossbeam 107, through which the upper ends of the two support screws 102 pass. Specifically, avoidance grooves 1071 can be provided at both ends of the crossbeam 107, through which the upper ends of the two support screws 102 pass, extending out of the crossbeam 107. The bottom ends of the two support screws 102 are connected to the base 101, and the upper ends are connected to the crossbeam 107. The crossbeam 107 is arranged parallel to the base 101, which can improve the rigidity of the clamping unit 100 and the integration of the clamping unit 100, facilitating storage and overall movement.

[0030] In one embodiment, an auxiliary rod 108 is disposed between the support screw 102 and the first compression screw 104. The auxiliary rod 108 is disposed parallel to the support screw 102. The bottom end of the auxiliary rod 108 is connected to the connecting plate 103, and the upper end passes through the crossbeam 107. When the connecting plate 103 moves up and down along the support screw 102, the auxiliary rod 108 moves up and down with the connecting plate 103. The auxiliary rod 108 prevents the connecting plate 103 from rotating about the support screw 102 and maintains the position of the connecting plate 103 as the connecting plate 103 moves up and down, allowing the first compression screw 104 to be positioned above the base 101 between the two support screws 102. This allows the first compression screw 104 to be conveniently and quickly pressed against the upper surface of the substitute wood blank 200 located above the base 101. Furthermore, the force exerted by the first compression screw 104 on the substitute wood blank 200 is directed vertically toward the base 101, preventing the substitute wood blank 200 from tilting. At the same time, the auxiliary rod 108 can also keep the connecting plate 103 horizontal, prevent one end of the connecting plate 103 from tilting, and keep the force direction of the first clamping screw 104 vertical, providing only a vertical downward clamping force to prevent the wooden blank 200 from sliding.

[0031] In one embodiment, a second compression screw 109 is provided in the middle of the crossbeam 107 and is arranged parallel to the support screw 102. The second compression screw 109 is threadedly connected to the crossbeam 107. A second nut 110 is threadedly connected to the support screw 102, and the second nut 110 is located above the crossbeam 107. When the horizontal dimension of the substitute wood blank 200 is large, the crossbeam 107 is moved downward, and the second compression screw 109 is rotated so that the bottom end of the second compression screw 109 contacts the upper surface of the substitute wood blank 200. The second compression screw 109 is further rotated to press the middle of the substitute wood blank 200 downward, thereby providing a compression force to the middle of the substitute wood blank 200 and balancing the clamping force of the two substitute wood blanks 200. When the second clamping screw 109 is rotated into place, tighten the second nut 110 so that the second nut 110 fits the beam 107, which can fix the beam 107 between the second nut 110 and the wood blank 200 to prevent the beam 107 from moving upward, making the height of the second clamping screw 109 stable, thereby keeping the clamping force of the second clamping screw 109 stable.

[0032] In one embodiment, a second pressing plate 111 is provided at the bottom of the second pressing screw 109, and the second pressing plate 111 is connected to the second pressing screw 109 via a second ball nut; alternatively, the second pressing plate 111 is provided with a second blind threaded hole, and the second pressing screw 109 is threadedly connected to the second blind threaded hole. When the second pressing screw 109 rotates downward, the second pressing plate 111 contacts the substitute wood blank 200, and when the second pressing screw 109 continues to rotate, the second pressing plate 111 and the second pressing screw 109 form a screw transmission. The second pressing plate 111 does not rotate around the second pressing screw 109, but only moves vertically downward, applying vertical pressure to the substitute wood blank 200 to prevent the substitute wood blank 200 from sliding. The second pressing plate 111 can be configured with a larger lateral dimension. The second pressing plate 111 can move vertically downward, and can also prevent the second pressing plate 111 from changing position as the second pressing screw 109 rotates, so that the second pressing plate 111 presses against the upper surface of the substitute wood blank 200 above the base 101, preventing the substitute wood blank 200 from tilting. The second pressing plate 111 pressing the substitute wood blank 200 can also prevent the second pressing screw 109 from directly pressing the substitute wood blank 200 and rotating and pressing, thereby preventing deep marks from being left on the surface of the substitute wood blank 200.

[0033] In order to make the pressing force more balanced, a plurality of pressing columns 112 can be set at the bottom of the second pressing plate 111. The length of each pressing column 112 extending out of the second pressing plate 111 is the same. When the second pressing plate 111 moves downward, each pressing column 112 contacts the upper surface of the substitute wood blank 200 at the same time, and forms a small area of ​​dispersed contact with the substitute wood blank 200, so that the force on the substitute wood blank 200 is dispersed and balanced.

[0034] In one embodiment, handles are provided at the upper ends of the first pressing screw 104 and the second pressing screw 109 to facilitate the rotation of the first pressing screw 104 and the second pressing screw 109 .

[0035] To accommodate substitute wood blanks 200 of varying sizes, the tool includes multiple clamping units 100. For smaller substitute wood blanks 200, a single clamping unit 100 can be used to clamp the center of the substitute wood blank 200. For larger substitute wood blanks 200, multiple clamping units 100 can be used to clamp the substitute wood blank 200 at different locations. For example, two clamping units 100 can be used to clamp each end of the substitute wood blank 200, or three clamping units 100 can be used to clamp each end and the center of the substitute wood blank 200. The clamping units 100 can be made of 45-gauge steel for durability.

[0036] In one embodiment, the tool further comprises a table, and the base 101 is embedded in the table, with the upper surface of the base 101 not higher than the table. When using the tool, the substitute wood blank 200 can be placed on the table, providing a more stable support for the substitute wood blank 200 and preventing the substitute wood blank 200 from warping or deforming.

[0037] The method of using the tool to clamp the wood blank 200 is as follows:

[0038] like Figure 2 As shown, after the two substitute wood blanks 200 are bonded by the substitute wood glue 300, the bonded substitute wood blanks 200 are placed on the base 101. Move the connecting plate 103 downward along the support screw 102 so that the first clamping plate 105 contacts the upper surface of the substitute wood blank 200. Preferably, the connecting plate 103 and the support screw 102 are clearance-matched, which facilitates the quick up and down movement of the connecting plate 103. Then rotate the first clamping screw 104 downward, the first clamping plate 105 presses the upper substitute wood blank 200 downward, the upper substitute wood blank 200 moves downward, and the substitute wood glue 300 overflows from all sides. Rotate the first clamping screw 104 to adjust the distance between the two substitute wood blanks 200 to an appropriate level, tighten the first nut 106 to fix the position of the connecting plate 103, and the two substitute wood blanks 200 can be stably clamped. Next, move the crossbeam 107 downward and rotate the second compression screw 109 until the compression post 112 contacts the upper surface of the substitute wood blank 200. Tighten the second nut 110 to secure the crossbeam 107 in place, clamping the center of the substitute wood blank 200 and ensuring balanced force distribution. When using multiple clamping units 100, tighten each clamping unit 100 to complete the gluing of the substitute wood blank 200. After the substitute wood glue 300 has cured for eight hours, the tools are removed, revealing that the substitute wood blank 200 is firmly bonded and ready for CNC machining.

[0039] During operation, the clamping units 100 at both ends of the substitute wood blank 200 can be tightened first, followed by the clamping unit 100 in the middle of the substitute wood blank 200. The two first compression screws 104 can also be rotated simultaneously to move both sides of the upper substitute wood blank 200 downward simultaneously. The thickness of the substitute wood glue 300 can be measured with a caliper or by comparing it with a shim of corresponding thickness. When the distance between the two substitute wood blanks 200 is approximately 0.3 mm, the rotation of the first compression screws 104 can be stopped.

[0040] The tool can apply a vertical downward pressing force to the substitute wood blank 200 through the pressing screw, and can fix the substitute wood blank 200 during the bonding process to prevent the substitute wood blank 200 from sliding during the curing process of the substitute wood glue 300. The substitute wood blank 200 is evenly stressed, and by controlling the downward rotation process of the pressing screw, the downward displacement of the upper substitute wood blank 200 can be controlled, thereby controlling the thickness of the applied substitute wood glue 300. The accurate control can save material usage and make the substitute wood glue 300 evenly coated, solving the problem of inadequate bonding inside the substitute wood blank 200, and improving the bonding efficiency and bonding dimensional accuracy of the substitute wood blank 200. The tool has a simple structure and is easy to operate. It can standardize the operation of the substitute wood bonding process, improve the efficiency of rough processing of workpieces, and improve the work efficiency of operators.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
