Description

Technical Field

[0001] This invention relates to the field of wooden workpiece processing, and in particular to a drilling device for double 45-degree beveled pin holes at both ends of wooden workpieces. Background Technology

[0002] Tripods are common support components for wall-mounted furniture. For wall-mounted wooden furniture, wooden tripods are typically used. The general structure of a wooden tripod is as follows: Figure 1 As shown, it consists of horizontal support bars, vertical support bars, and diagonal support bars. The end faces of the diagonal support bars are 45-degree slopes, and pin holes perpendicular to the 45-degree slopes are machined on the end faces of the diagonal support bars. The diagonal support bars are connected to the horizontal support bars and vertical support bars by two wooden pins.

[0003] Currently, there is no dedicated equipment for machining pin holes on the 45-degree bevels at both ends of a diagonal support bar. Machining these pin holes on existing general-purpose drilling machines requires clamping the support bar at a 45-degree angle, ensuring the 45-degree bevel at the upward-facing end is horizontal, and then drilling vertically downwards from that end. After drilling, the support bar is rotated so the other end is upwards and the 45-degree bevel is horizontal, and the vertical downward drilling is repeated. It is clear that this entire process is time-consuming and inefficient.

[0004] Because the two ends of the diagonal support bar need to be pinned to the horizontal and vertical support bars respectively, and the two wooden pins are perpendicular to each other, any positional deviation of the pin holes at either end will prevent both from being simultaneously aligned with the pin holes on the horizontal and vertical support bars. This is the first technical problem in achieving automatic machining of the double 45-degree beveled pin holes at both ends of the diagonal support bar.

[0005] According to common sense, the position of a vertical hole on a plane is determined by its position in both the longitudinal and transverse directions. To locate a vertical hole on a plane, positioning is required in both the longitudinal and transverse directions. For a slanted support bar, if the end of the slanted support bar is flat, then machining a vertical pin hole on its end face only requires positioning its four sides to achieve the positioning of the pin hole to be machined. However, the pin hole to be machined in this invention is actually located on the 45-degree slanted surface at the end. In this case, positioning only the four sides of the slanted support bar is not enough to achieve the positioning of the pin hole to be machined; further positioning of both ends of the slanted support bar is also required. Obviously, there is a conflict between the positioning components set for positioning at both ends and the drilling device for machining the pin hole at both ends. This is the second technical problem in realizing the automatic machining of pin holes on the double 45-degree slanted surfaces at both ends of the slanted support bar.

[0006] Furthermore, to automate the machining process, feeding and discharging mechanisms are required for the machining equipment. However, as analyzed earlier, positioning elements are needed in all six directions of the inclined support bar. Regardless of which direction the feeding and discharging mechanisms are positioned in the machining area, they are likely to conflict with the positioning elements in that direction. This is the third technical problem in achieving automatic machining of the double 45-degree inclined pin holes at both ends of the inclined support bar. In addition, the feeding and discharging mechanisms may also conflict with the drilling device. This is the fourth technical problem in achieving automatic machining of the double 45-degree inclined pin holes at both ends of the inclined support bar.

[0007] It is evident that designing a dedicated machine to automatically machine the double 45-degree beveled pin holes at both ends of the inclined support bar requires simultaneously solving the four technical problems mentioned above. Understandably, these four problems are not independent but interconnected; solving one problem may hinder the solution of another. For example, solving the first technical problem by simultaneously machining the pin holes at both ends could lead to conflicts between the positioning components at both ends and the drilling devices at both ends. Therefore, solving all four technical problems simultaneously is more difficult than solving them individually. Summary of the Invention

[0008] The purpose of this invention is to solve the problem of low efficiency in machining the 45-degree beveled pin holes at both ends of the inclined support bar of a wooden tripod using existing general-purpose drilling machines. Based on automatic feeding and unloading, and the simultaneous completion of machining the 45-degree beveled pin holes at both ends on the conveying path, this invention constructs a drilling device for machining double 45-degree beveled pin holes at both ends of wooden workpieces specifically for machining the pin holes at both ends of the inclined support bar of a wooden tripod.

[0009] A drilling device for double 45-degree beveled pin holes at both ends of a wooden workpiece, comprising an installation platform, characterized in that the installation platform is equipped with a feeding device for pushing the wooden workpiece to be processed forward into the drilling station, a fixing device for fixing the wooden workpiece to be processed, an electric drill device located on both sides at an angle above for simultaneously drilling holes at both ends of the wooden workpiece, and a discharge device for pushing the drilled workpiece out of the drilling station laterally.

[0010] The fixing device includes a positioning plate for positioning the rear side of the workpiece, a rigid positioning foot for positioning the first end of the workpiece, an elastic positioning foot for positioning the second end of the workpiece, and a fixed pressure foot that can be raised and lowered to press the workpiece down from above. The discharge device is located on the side where the elastic positioning foot is located.

[0011] The rigid positioning foot is vertically adjustable, and the rigid positioning foot has a notch corresponding to the position of the first end pin hole. The elastic positioning foot is equipped with a drill bit and discharge push rod avoidance structure.

[0012] Furthermore, the feeding device includes a first cylinder, a push cover plate, a first wedge-shaped guide, and a second wedge-shaped guide. The first cylinder is lowered and disposed on the mounting platform. The push cover plate is fixedly installed on the push plate of the first cylinder. The first wedge-shaped guide and the second wedge-shaped guide are respectively installed on both sides of the first cylinder.

[0013] Specifically, the installation height of the push cover is less than the height of the wooden workpiece to be processed, and the shape of the opposite end face of the first wedge guide and the second wedge guide and the distance between the end face correspond one-to-one with the shape of the two end face and the distance between the end face of the wooden piece to be processed.

[0014] Furthermore, the discharge device adopts a cylinder structure, specifically a second cylinder, which is fixedly installed on the side of the wooden workpiece that contacts the elastic positioning foot and extends in a direction perpendicular to the pushing direction of the first cylinder.

[0015] Furthermore, the mounting platform is also equipped with a stacking assembly that allows the wooden workpieces to be processed to be stacked sequentially.

[0016] Furthermore, the material stacking assembly includes an L-shaped guide plate, an arc-shaped guide plate, and L-shaped fasteners. Two L-shaped fasteners are fixedly installed on the mounting platform and are symmetrical about the center of the first cylinder. Two L-shaped guide plates, which are symmetrical about the center of the first cylinder, are respectively fixedly installed on the end faces of the two L-shaped fasteners near the center of symmetry. Two arc-shaped guide plates, which are symmetrical about the center of the first cylinder, are fixedly installed on the end faces of the two L-shaped guide plates near the center of symmetry.

[0017] Specifically, the bottom of the side plate of the L-shaped guide plate perpendicular to the first cylinder's ejection direction is provided with a suspended area that allows only one piece of wooden workpiece to be processed to move. The distance between the end faces of the vertical plates of the L-shaped guide plate parallel to the first cylinder's ejection direction near the center of symmetry is the length of the wooden workpiece to be processed. The bottom of the arc-shaped side plate of the arc-shaped guide plate perpendicular to the first cylinder's ejection direction is also provided with a suspended area that allows only one piece of wooden workpiece to be processed to move. The distance between the end faces of the arc-shaped side plate of the arc-shaped guide plate and the side plate of the L-shaped guide plate that are close to each other is the width of the wooden workpiece to be processed.

[0018] Furthermore, the electric drill is equipped with an adjustment component for adjusting its drilling position. The electric drill is mounted on the mounting platform via the adjustment component. Both the electric drill and the adjustment component are provided in two sets, and the two sets of the electric drill and the adjustment component are symmetrical about the center of the wooden workpiece to be processed.

[0019] Furthermore, each set of adjustment components includes a lifting mounting bracket, a first dovetail slide group, a second dovetail slide group, and an air pump slide. The lifting mounting bracket is fixedly installed on the mounting platform, the first dovetail slide group is fixedly installed on the mounting platform, the second dovetail slide group is slidably connected to the first dovetail slide group, the air pump slide is slidably connected to the second dovetail slide group through a connector, and the electric drill is fixedly installed on the air pump slide.

[0020] Furthermore, the first dovetail slide assembly includes a first dovetail slide, a first lead screw, and a first handwheel. The first dovetail slide is fixedly mounted on the lifting mounting bracket, the first lead screw is rotatably mounted on the first dovetail slide, and the first handwheel is fixedly mounted on the extension end of the first lead screw.

[0021] The second dovetail slide assembly includes a second dovetail slide, a second lead screw, and a second handwheel. The second dovetail slide is fixedly connected to the lead screw slide mounted on the first lead screw. The second lead screw is rotatably mounted on the second dovetail slide, and the second handwheel is fixedly mounted on the extension end of the second lead screw.

[0022] The air pump slide is fixedly connected to the lead screw slide mounted on the second lead screw via a connector.

[0023] Specifically, the air pump slide is set at a 45° angle to the horizontal plane, and the electric drill is also set at a 45° angle to the horizontal plane. The processing angles of the electric drills located on both sides of the wooden workpiece to be processed are perpendicular to the two processing end faces of the wooden workpiece.

[0024] The beneficial effects of the present invention are as follows: The drilling equipment for double 45-degree beveled pin holes at both ends of a wooden workpiece disclosed in this application completes the processing of two pin holes in one positioning. The relative hole positions of the two pin holes are determined by the relative positional relationship of the two drilling devices and are not affected by positioning errors. Therefore, it can effectively avoid deviations in the relative hole positions of the two pin holes due to positioning errors.

[0025] Based on this, the feeding mechanism in this application, in conjunction with the positioning plate to limit the position, has its own positioning function and the position of the feeding mechanism avoids the position of the drilling device. At the same time, both the rigid positioning foot and the fixed pressure foot are set in a liftable manner, and the positioning component in the direction of the discharge device is selected as the elastic positioning foot, and both the rigid positioning foot and the elastic positioning foot are provided with a clearance structure.

[0026] The above technical features simultaneously solve the problems of the pin holes at both ends being aligned with the pin holes on the horizontal and vertical support bars, the conflict between the positioning component set at both ends and the drilling device that performs pin hole processing at both ends, the feeding mechanism and the discharging mechanism being suspected of conflicting with the positioning component in this direction, and the feeding mechanism and the discharging mechanism also potentially conflicting with the drilling device.

In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

The upper end of the arc-shaped side plate of the arc-shaped guide plate 111 bends away from the side plate of the L-shaped guide plate 105. The larger rectangular face of the wooden workpiece is placed down, and the smaller rectangular face is placed up. The lower ends of the side plates of the L-shaped guide plate 105 and the arc-shaped side plates of the arc-shaped guide plate 111 are provided with overhangs.

[0043] The wooden mounting platform 104 has an upward-opening mounting groove, which is located between the aforementioned stacking components.

The left end face of the first wedge-shaped guide 128 corresponds to the inclination angle of the right end face of the wooden workpiece to be processed, and the right end face of the second wedge-shaped guide 130 corresponds to the inclination angle of the left end face of the wooden workpiece to be processed. The distance between the first wedge-shaped guide 128 and the second wedge-shaped guide 130 is just enough to allow the wooden workpiece to be processed to move in an oriented manner. A spring plate 129 (the spring plate 129 is the above-mentioned elastic positioning foot) is fixedly installed on the right end of the first wedge-shaped guide 128. The spring plate 129 bends to the left and presses against the right end face of the wooden workpiece.

The push plate in the third cylinder 132 extends downward and a fixed pressure foot 133 is fixedly installed on the lower end face of the push plate.

[0046] A mounting connector 124 is fixedly installed on the mounting plane 103 in front of the wooden mounting platform 104. A fourth cylinder 125 is fixedly installed on the upper end face of the mounting connector 124. The push plate in the fourth cylinder 125 is fixedly connected to the mounting connector 124. A rigid positioning foot 131 is fixedly installed on the left end face of the cylinder body in the fourth cylinder 125. The rear end of the rigid positioning foot 131 is a 45° inclined surface that can press against the left end face of the wooden workpiece. The rear end of the rigid positioning foot 131 is also provided with a groove to avoid the drill bit.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, two sets of symmetrically positioned adjustment components and electric drill devices are fixedly installed on the upper surface of the mounting plane 103. Two sets of symmetrically positioned lifting mounting frames are also fixedly installed on the upper surface of the mounting plane 103. Each set of lifting mounting frames consists of two symmetrically positioned C-shaped brackets 118. A first dovetail slide 119 is fixedly installed on the upper surface of each set of lifting mounting frames. The dovetail surface of the first dovetail slide 119 faces upward. A connecting groove that runs vertically through the first dovetail slide 119 is provided inside the first dovetail slide 119. A first lead screw 121 is rotatably connected to the position of the connecting groove on the first dovetail slide 119. One end of the first lead screw 121, away from the center of symmetry, extends to the outside of the first dovetail slide 119, and a first handwheel 120 is fixedly installed at this end. A lead screw slider is threadedly connected to the first lead screw 121, and the upper surface of the lead screw slider is fixedly connected to a second dovetail slide 117. The second dovetail slide 117 is slidably installed on the dovetail surface of the first dovetail slide 119.

[0048] The dovetail face of the second dovetail slide 117 faces rearward. The second dovetail slide 117 is provided with a connecting groove that runs through the front and rear. The second lead screw 116 is rotatably connected to the position of the connecting groove on the second dovetail slide 117. The second lead screw 116 extends upward to the outside of the second dovetail slide 117 and a second handwheel 115 is fixedly installed at its end. A lead screw slider is threadedly connected to the second lead screw 116 and the rear end face of the lead screw slider is fixedly connected to the sliding connector 122. The sliding connector 122 is slidably installed on the dovetail face of the second dovetail slide 117.

[0049] An air pump mounting plate 123 is fixedly installed on the rear end face of the sliding connector 122. An air pump slide 114 inclined at a 45° angle is fixedly installed on the rear end face of the air pump mounting plate 123. An electric drill device 113 is fixedly installed on the rear end face of the air pump slide 114, and the electric drill device 113 is also inclined at a 45° angle.

[0050] The air pump slide 114 and electric drill device 113 on the right side form a counterclockwise angle of 45° with the horizontal line, while the air pump slide 114 and electric drill device 113 on the left side form a clockwise angle of 45° with the horizontal line.

[0051] like Figure 2 and Figure 6 As shown, two cylinder mounting plates 108 are fixedly installed on the right side of the wooden mounting platform 104 and on the upper surface of the mounting plane 103. A second cylinder 107 is fixedly installed between the cylinder mounting plates 108. The push rod in the second cylinder 107 extends to the left and can push the processed wooden workpiece to the left after being pushed out. A soft contact head 127 is fixedly installed on the extended end of the push rod in the second cylinder 107.

[0052] When starting work,

[0053] (1) Manually rotate the second handwheel 115 and the first handwheel 120 to move the electric drill 113 to the drilling position corresponding to the wooden workpiece to be processed;

[0054] (2) The push rod in the fourth cylinder 125 retracts, causing the cylinder body of the fourth cylinder 125 to move downward. The downward movement of the cylinder body of the fourth cylinder 125 drives the rigid positioning foot 131 to move downward to the designated position.

[0055] (3) The push rod in the first cylinder 109 drives the push plate to extend, causing the push cover plate 110 fixedly connected to it to move forward. The push cover plate 110 moves forward and pushes the wooden workpiece placed between the arc guide plate 111 and the L-shaped guide plate 105 to move forward in a directional direction until the front end of the wooden workpiece abuts against the positioning plate 126. The push rod in the third cylinder 132 extends, causing the fixed press foot 133 connected to it to move downward and fix the wooden workpiece to be processed. The push rod in the first cylinder 109 retracts and drives the push cover plate 110 back to the initial position. The wooden workpiece placed between the arc guide plate 111 and the L-shaped guide plate 105 falls.

[0056] (4) The electric drill devices 113 on the left and right sides are started and the air pump slide 114 pushes the electric drill devices 113 on the left and right sides toward the two 45° inclined planes perpendicular to the left and right ends of the wooden workpiece, respectively, and completes the drilling of the pin holes on the double 45° inclined planes at both ends of the wooden workpiece.

[0057] (5) The push rod in the fourth cylinder 125 extends to raise its cylinder body. The rise of the cylinder body in the fourth cylinder 125 drives the rigid positioning foot 131 to move upward. The push rod in the second cylinder 107 extends to push the soft contact head 127 installed on the push rod to move the processed wooden workpiece to the loading platform 102.

[0058] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
