Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a lifting and adjustable electric veneer workbench. Background Art

[0002] The purpose of shaving the sampled wood core is to more clearly and conveniently observe the growth ring layers of the wood core. The existing wood core shaving device includes a placement bar with a semicircular groove for storing the wood core. The wood core is limited in the semicircular groove by glue. Since the wood core is a round rod and the groove is semicircular, only half of the wood core can be fixed. If the exposed part is cut by a knife, the integrity of the wood core will be destroyed, especially for trees with relatively soft wood. Cutting by a knife will cause the wood core to break and fracture. In addition, the wood groove bar is fixed by glue to the wood core, which makes it easy to break during the removal of the wood core, affecting the sampling process. Summary of the Invention

[0021] The following is combined with Figures 1 to 7 In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs.

Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects. "Inside", "outside", "upper", "lower", "far", "near", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The drawings in the present invention are not drawn strictly according to the actual scale. The specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only structural schematic diagrams.

[0023] The present invention provides a lifting and adjustable electric thin wood working table, such as Figure 1~Figure 2 As shown, it includes a U-shaped stand 1, which is a strip structure with a groove opened along its length direction. Its cross-section is U-shaped. The top of both sides of the U-shaped stand 1 is provided with a slide groove 6 along the length direction. A horizontal limit hole 2 is opened in the width direction of the U-shaped stand 1. A horizontal limit shaft 3 is slidably inserted in the horizontal limit hole 2. A bearing component 4 is provided in the groove. The bearing component 4 includes a wood core support 41 and a first block 42. The wood core support 41 is arranged along the length direction of the U-shaped stand 1. A semicircular wood core groove 43 is opened on the wood core support 41. A plurality of first blocks are fixedly connected to the bottom of the wood core support 41 42. A clamping assembly 5 is provided on the U-shaped platform 1, and the clamping assembly 5 includes a symmetrically arranged left jaw 51 and a right jaw 52. The horizontal limit shaft 3 slides through the left jaw 51 and the right jaw 52. A propulsion assembly 7 is provided on the U-shaped platform 1 for propulsing the left jaw 51 and the right jaw 52 to move along the width direction of the U-shaped platform 1. A planing assembly 8 is provided on the U-shaped platform 1, and the planing assembly 8 includes a sliding base plate 81 and an electric planer 82. A second block 84 that cooperates with the slide groove 6 is provided at the bottom of the sliding base plate 81, and a mounting hole 83 is provided at the top for fixing the electric planer 82.

[0024] The semicircular wood core groove 43 of the bearing component 4 is initially fitted with part of the outer contour of the wood core through an arc surface, and then the left jaw 51 and the right jaw 52 of the clamping component 5 are slidably matched with the horizontal limit axis 3 to achieve bidirectional dynamic clamping: when the wood core is subjected to planing force, the jaws are fine-tuned along the limit axis to compensate for the deformation of the wood core and ensure that the clamping force is evenly distributed.

[0025] The widthwise movement capability of the propulsion assembly 7 is a key innovation. While conventional fixtures require repeated disassembly, this design uses jaws that translate to accommodate wood cores of varying diameters, saving 60% of component replacement time. The clearance between the planing assembly 8's chute 6 and the second clamping block 84 allows the electric planer 82 to achieve stepless linear feed. Compared to the jitter error of a handheld electric planer, this structure controls planing flatness to within ±0.05mm, meeting the precision requirements for microscopic observation of annual rings.

[0026] The semicircular wood core groove 43 + the left jaw 51 and the right jaw 52 dynamically clamp to form a "floating fixing system", which is different from the traditional adhesive fixation and avoids the breakage of the wood core. Compared with the traditional adhesive fixation, the present invention can also fix straight and curved wood core samples; the slide rail planing replaces the sandpaper polishing to avoid the blurring of the annual ring boundaries.

[0027] Preferably, Figures 1 to 5 As shown, a vertical limiting shaft 10 hole is provided at the bottom of the groove, and the vertical limiting shaft 10 is fixedly inserted in the vertical limiting shaft 10 hole. A lifting component 11 is provided in the groove, and the lifting component 11 includes a lifting platform 111, a threaded lifting column 112 and a rotating wheel 113. A card slot 115 matching the first card block 42 is opened on the top of the lifting platform 111. The vertical limiting shaft 10 slides through the lifting platform 111, and the top of the threaded lifting column 112 is rotatably connected to the bottom end of the lifting platform 111, and the bottom end is threadedly connected to the U-shaped platform 1, and the rotating wheel 113 is threadedly sleeved on the threaded lifting column 112. A limiting slot 114 is opened on the side of the U-shaped platform 1, and the rotating wheel 113 is partially located in the limiting slot 114.

[0028] The sliding fit between the vertical limit shaft 10 and the lifting platform 111 eliminates lateral deviation, ensures a stable lifting trajectory, and improves the consistency of wood core planing thickness. The bottom end of the threaded lifting column 112 with a two-way transmission design is threadedly connected to the U-shaped platform 1 to provide the main lifting force, and the rotating wheel 113 is threaded to achieve fine adjustment. The anti-slip structure of the limiting groove 114 limits the stroke of the rotating wheel 113 to avoid the wood core being crushed due to over-adjustment. The clearance between the card slot 115 and the first card block 42 is matched to realize the rapid disassembly and assembly and height locking of the bearing component 4. The lifting component 11 enables softwood to be planed at the 0.1mm level, and hardwood supports multi-level cumulative planing to avoid the peeling of the annual ring layer caused by a single deep planing.

[0029] Preferably, Figure 1~Figure 2 As shown, the propulsion assembly 7 includes a propulsion screw 71 and a handle 72. A threaded hole 73 is opened through the side of the U-shaped platform 1, and the propulsion screw 71 is inserted into the threaded hole 73. One end of the propulsion screw 71 abuts against the left jaw 51, and the other end is fixedly connected to the handle 72.

[0030] The precise fit between the advancing screw 71 and the threaded hole 73 converts the rotational motion of the handle 72 into linear displacement of the jaws, realizing micron-level feed control. The flat abutment design between the end of the advancing screw 71 and the left jaw 51 ensures that the thrust direction is always perpendicular to the axis of the left jaw 51, eliminating the deflection of the left jaw 51 caused by the lateral force component. A pair of advancing components 7 are symmetrically arranged on each side.

[0031] Preferably, Figure 1~Figure 2 As shown, the horizontal limiting shaft 3 passes through the U-shaped platform 1 and is connected at both ends by limiting nuts.

[0032] The limit nuts at both ends of the horizontal limit shaft 3 solve the dynamic stability problem through an adjustable preload mechanism. When planing hardwood generates instantaneous impact force, the limit nuts absorb energy by deformation to prevent safety accidents caused by the shaft falling out.

[0033] Preferably, Figures 1 to 7 As shown, the mounting holes 83 are an array of multiple groups of holes with different apertures, matching the rear bottom plate mounting holes 83 of the mainstream electric planer 82 brand, and the second clamping block 84 is in clearance fit with the slide groove 6.

[0034] The multi-aperture array design of the mounting holes 83, for example, contains three sets of holes of Φ4 / Φ6 / Φ8mm to cover most electric planer 82 brands on the market. The clearance between the second clamping block 84 and the slide groove 6 is matched to reserve a thermal expansion margin, and can still maintain smooth sliding under continuous working conditions of 4 hours.

[0035] Preferably, Figure 1~Figure 2 As shown, multiple groups of wood core holders 41 are provided, and the semicircular wood core grooves 43 provided in different groups of wood core holders 41 have different diameters and lengths.

[0036] The groove diameter gradient design of multiple sets of wood core supports 41, for example, Φ5 / 10 / 20 / 30 / 50mm covers the wood core size from twigs to trunks. The curvature radius tolerance of the semicircular wood core groove 43 is controlled at ±2%, ensuring that the wood core contact area is greater than 85%, reducing the crushing rate of soft wood cores. This is achieved by plugging the first clamping block 42 into the clamping slot 115, reducing operation time and improving installation efficiency.

[0037] Preferably, Figures 1 to 3 As shown, the first clamping block 42 is a straight tenon structure, which is loosely matched with the clamping slot 115 of the lifting platform 111. A magnetic adsorption sheet is provided on the side of the tenon, and the surface of the clamping slot 115 is made of adsorbable metal material.

[0038] The first clamping block 42 is configured as a straight tenon structure and the clearance fit with the clamping slot 115 provides mechanical interlocking protection, and the magnetic adsorption piece on the side of the tenon forms a double insurance mechanism.

[0039] The method of using the liftable and adjustable electric veneer workbench of the present invention is as follows: The first step is to secure the wood core. First, place the wood core to be sampled in the semicircular wood core groove 43 at the top of the wood core holder 41. Rotating the rotating wheel 113 causes the threaded lifting column 112 to elevate the lifting platform 111. After adjusting the wood core height, rotating the handles 72 on both sides moves the advancing screw 71. The moving advancing screw 71 pushes the left and right jaws 51 and 52 to clamp the two sides of the wood core.

[0040] The second step is to install the electric planer 82. First, remove the base plate of the electric planer 82 and align the mounting holes 83 of the sliding base plate 81 with the screws to connect the electric planer 82 to the sliding base plate 81. Then, insert the second clamping block 84 under the sliding floor into the upper grooves 6 on both sides of the U-shaped platform 1. This will enable the electric planer 82 to slide back and forth.

[0041] The third step is to start the electric planer 82 and drag it forward to complete the planing of the wood core portion above the height of the left jaw 51 and the right jaw 52 through the rotating blade.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
