DETAILED DESCRIPTION

[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0030] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] like Figure 1 The high-precision tenon sawing and drilling machine shown in FIG. 8 includes a machine body 10, a positioning assembly 30, and a processing tool 80. A processing platform 20 and a driving member of the processing platform 20 are provided on the machine body 10. Two abutment plates 21 are provided on the processing platform 20, and the ends of the two abutment plates 21 are vertically abutted. The abutment plates 21 can be used for abutment of workpieces, and the two abutment plates 21 can allow two workpieces to be in a 90-degree vertical abutment state. In addition, the driving member of the processing platform 20 is used to drive the processing platform 20 to move along a processing direction.

[0033] Specifically, the positioning assembly 30 includes a positioning plate 31 and a positioning plate driving member 32. The positioning plate 31 is arranged on one side of the processing platform 20. The positioning plate 31 can also be used for the workpiece to be positioned against. The positioning plate 31 has a supporting surface 311, and the supporting surface 311 is parallel to one of the supporting plates 21. The positioning plate driving member 32 is used to drive the positioning plate 31 to move closer to or away from the processing platform 20. The processing tool 80 is arranged on one side of the processing platform 20 and is used to process the workpiece. The positioning assembly 30 and the processing tool 80 are spaced apart in the processing direction.

[0034] On the basis of the above structure, when using the high-precision tenon sawing and drilling machine of the present invention, during processing, two workpieces can be simultaneously abutted against the two abutment plates 21, and the ends of the two workpieces are vertically arranged. Before processing, the processing platform 20 driving member can be used to drive the processing platform 20 to move to the positioning assembly 30, and then the positioning plate driving member 32 can drive the positioning plate 31 to move toward the processing platform 20, and the abutment surface 311 abuts against the side of the workpiece away from the abutment plate 21. Since the abutment surface 311 is parallel to the extension direction of the abutment plate 21, after the abutment surface 311 abuts against the workpiece, the workpiece can be tightly attached to the abutment plate 21. After positioning and abutting, the two workpieces can be positioned and placed at a 45-degree angle with the angle bisector of the two abutment plates 21, which is convenient for the two workpieces to abut stably and with high positioning accuracy.

[0035] Afterwards, the processing platform 20 is driven by the driving member of the processing platform 20 to move to the processing tool 80 for processing. The processing tool 80 can process the ends of the two workpieces. Since the processing direction is a linear direction, the two workpieces are pushed to the processing tool 80 in turn, and the end faces formed by cutting are mutually matching 45-degree inclined surfaces 411. After the mortise and tenon structure is processed, they are directly assembled at a higher precision.

[0036] After the same end of the two workpieces is processed, one end of the workpiece can be exchanged and clamped on the abutment plate 21 again to process the other end. It is also positioned by the abutment surface 311 of the above-mentioned positioning component 30. Since the angle of the abutment surface 311 remains unchanged, the inclination angle of the end face formed by processing is the same.

[0037] It should be noted that the driving member of the processing platform 20 can be realized by a screw transmission mechanism in the prior art, which adopts threaded matching transmission and has high driving precision. The positioning plate driving member 32 can be a cylinder.

[0038] Furthermore, the positioning support plate of the present embodiment is provided with abutment surfaces 311 on both sides of the processing direction, one of the abutment surfaces 311 is parallel to one of the positioning support plates 31; the other abutment surface 311 is parallel to the other positioning support plate 31, that is, when the workpiece is positioned and abutted, the driving member of the processing platform 20 first drives one of the workpieces in the front in the processing direction and one of the abutment surfaces 311 parallel thereto to abut and position, and then the driving member of the processing platform 20 continues to advance the processing platform 20, and the other workpiece in the back in the processing direction can be abutted and positioned with the other abutment surface 311 parallel thereto, and the same positioning support plate 31 can realize two-way positioning, and the positioning efficiency is better.

[0039] Of course, two positioning assemblies 30 may also be provided on the machine body 10 , and the positioning abutment plates 31 of different positioning assemblies 30 have abutment surfaces 311 parallel to different abutment plates 21 .

[0040] Furthermore, two pushing guide assemblies 60 are provided on the processing platform 20, and each pushing guide assembly 60 is arranged at a corresponding interval with each abutment plate 21, that is, after the workpiece abuts against the abutment plate 21, the pushing guide assembly 60 is located on the outer side of the workpiece relative to the abutment plate 21.

[0041] The specific pushing guide assembly 60 includes a pushing rod 62, a pushing wheel 61 and a pushing rod driving member 63. One end of the pushing rod 62 is hinged on the processing platform 20, and the pushing wheel 61 is pivotally connected to the other end of the pushing rod 62; the pushing wheel 61 is spaced apart from the abutting plate 21; the pushing rod driving member 63 is used to drive the pushing rod 62 to rotate.

[0042] When the workpiece is being processed, the pushing rod 62 can be driven by the pushing rod driving member 63 to rotate close to the abutment plate 21, and the pushing wheel 61 on the pushing rod 62 can abut against the outside of the workpiece to prevent the workpiece from being pushed in or deviating during processing; and the pushing wheel 61 and the outer side surface of the workpiece can roll together to give the workpiece a certain degree of freedom, avoiding the situation where the workpiece is stuck during processing due to direct pressing.

[0043] More specifically, the push guide assembly 60 further includes a moving plate, on which the push rod 62, the push wheel 61 and the push rod driving member 63 are all mounted, and the moving plate can move along the processing direction. Specifically, a slide groove extending along the processing direction can be provided on the processing platform 20, and the moving plate can slide with the slide groove through a slide rail, so that the position of the push wheel 61 can be adjusted according to the width of the workpiece, which is suitable for processing workpieces of different widths.

[0044] Of course, the above-mentioned push rod driving member 63 can be selected to be a cylinder in the prior art, and the piston rod of the cylinder can be hinged to the push rod 62.

[0045] Furthermore, in this embodiment, a first wire drawing saw 70, a first wire drawing saw driving member 71 and a lifting driving member for the first wire drawing saw 70 may be provided on the body 10. Specifically, the first wire drawing saw 70 is pivotally connected to the body 10. The first wire drawing saw driving member 71 can drive the first wire drawing saw 70 to rotate. The first wire drawing saw 70 is located between the positioning assembly 30 and the processing tool 80. The lifting driving member for the first wire drawing saw 70 is used to drive the first wire drawing saw 70 to move along the height direction of the body 10.

[0046] On the basis of the above structure, when the processing platform 20 moves along the processing direction, the workpiece on the processing platform 20 can first pass through the first wire drawing saw 70, and the first wire drawing saw 70 can first move upward driven by the first wire drawing saw lifting member 72, and at the same time, the first wire drawing saw driving member 71 drives the first wire drawing saw 70 to rotate. In this way, the rotating first wire drawing saw 70 can first cut the bottom edge of the end of the workpiece to form a processing wire groove. Thereafter, the processing platform 20 is driven by the processing platform 20 driving member to move to the processing tool 80 for milling processing.

[0047] Since the end faces of the blades formed by direct milling of the wood board are prone to tearing during the actual processing, the first wire saw 70 can be used to cut and form processing grooves. In the later milling, milling can be performed directly at the processing grooves to prevent the end faces from tearing after processing. The formed processing end faces are smoother and the processing accuracy is higher.

[0048] After one of the workpieces is processed, the first line drawing saw 70 can be lowered to avoid space, so that the other workpiece can be transported to the right position, and then the first line drawing saw 70 can be raised to perform line drawing processing.

[0049] Furthermore, a pad 23 is provided on the processing platform 20, and the pad 23 can abut against one of the abutment plates 21, wherein a pad 23 is provided at a workpiece placement position on one side, and specifically, the pad 23 can be arranged on an abutment plate 21 relatively far back in the processing direction. In this way, after the workpiece is clamped in place, the two workpieces distributed front and back in the processing direction are placed at different heights, that is, in the processing direction of the first wire drawing saw 70, when the previous workpiece with a lower height moves to above the first wire drawing saw 70, the first wire drawing saw 70 can move upward under the action of the first wire drawing saw lifting member 72, and the first wire drawing saw 70 can process the previous workpiece during the rotation process. After that, the processing platform 20 moves along the processing direction, and pushes the other workpiece behind to the first wire drawing saw 70. Due to the action of the pad 23, it can avoid air, and then the first wire drawing saw 70 moves upward for processing.

[0050] Furthermore, the machine body is also provided with a first wire drawing saw moving part, which can drive the first wire drawing saw 70 to move closer to or away from the processing platform in the horizontal direction, that is, the first wire drawing saw moving part can drive the first wire drawing saw 70 to move, adjust the interval between the first wire drawing saw and the processing platform, thereby adjusting the interval between the first wire drawing saw and the end of the workpiece, which is convenient for processing. Of course, the first wire drawing saw moving part can also be realized by a cylinder structure.

[0051] More specifically, a second wire saw 50 and a second wire saw driving member 51 may be further provided on the machine body 10. The second wire saw 50 is located between the first wire saw 70 and the processing tool 80. That is, the first wire saw 70, the second wire saw 50 and the processing tool 80 are distributed in sequence in the processing direction, and the second wire saw driving member 51 is used to drive the second wire saw 50 to rotate.

[0052] In this way, the second wire drawing saw 50 and the first wire drawing saw 70 are distributed front and back in the processing direction, and the height of the second wire drawing saw 50 can be higher than the first wire drawing saw 70, that is, the second wire drawing saw 50 and the first wire drawing saw 70 distributed front and back in the processing direction can respectively draw lines on the end bottoms of the two workpieces, and the processing efficiency is higher.

[0053] Of course, the second wire saw 50 can also have another function, that is, after the workpiece is cut by the first wire saw 70 to form a processing groove, the processing platform 20 drives the workpiece to be pushed to the second wire saw 50, and the second wire saw driving member 51 drives the second wire saw 50 to rotate, and the processing groove can be cut at the top of the end of the workpiece. The specific selection can be made according to actual needs.

[0054] It should be noted that the first and second wire drawing saw driving members 71 and 51 driving the first and second wire drawing saws 70 and 50 can be implemented by motors or motors with transmission mechanisms (gear transmission, belt transmission, etc.) in the prior art. The first wire drawing saw lifting member 72 can be implemented by a linear motion output mechanism such as a cylinder.

[0055] Furthermore, a pressure block assembly 40 may be provided above the processing platform 20. Specifically, the pressure block assembly 40 includes a pressure block 41 and a pressure block driving member 42. The pressure block 41 is provided above the processing platform 20. The pressure block driving member 42 can drive the pressure block 41 to move along the height direction of the machine body 10. In this way, after the workpiece is clamped and abuts against the abutment plate 21, the pressure block 41 can be driven by the pressure block driving member 42 to move downward. During the downward movement of the pressure block 41, it can abut against the top surface of the workpiece, which makes the positioning structure of the workpiece more stable.

[0056] More specifically, the bottom end of the pressing block 41 is a slope 411, that is, when the pressing block 41 moves downward, the slope 411 at the bottom end of the pressing block 41 abuts against the end face of the workpiece, and the slope 411 can decompose the longitudinal force into a lateral force, which can push the workpiece to move closer to the abutment plate 21, so that the workpiece is tightly attached to the end face of the abutment plate 21, so that the positioning and clamping effect is better.

[0057] Of course, the above-mentioned pressing block driving member 42 can be realized by using a cylinder in the prior art, and the piston rod of the cylinder is connected to the pressing block 41 .

[0058] Furthermore, a grating ruler 22 may be provided on the abutment plate 21, and the grating ruler 22 can move along the extension direction of the abutment plate 21. In this way, when the workpiece is clamped for the first time, the grating ruler 22 can measure the clamping size of the workpiece. After the processing of one end of the workpiece is completed, the workpiece is turned around and installed, and can be clamped directly according to the measured size of the grating ruler 22, with better accuracy.

[0059] Furthermore, a waste conveying assembly 90 may be provided on the machine body 10, and the waste conveying assembly 90 includes a conveying belt and two conveying rollers, and the two conveying rollers are pivotally connected to the two ends of the machine body 10 in the processing direction; the two ends of the conveying belt are respectively pivotally connected to the outside of the two conveying rollers, and the conveying rollers are driven by the motor, and the conveying rollers rotate to drive the conveying belt to rotate. The conveying belt is located below the processing tool 80, the first wire drawing saw 70, and the second wire drawing saw 50. The conveying belt can receive wood chips generated during the processing, and the conveying belt can transport the wood chips to the outside of the machine body 10 for unified recycling.

[0060] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
