Description

Technical Field

[0001] This invention relates to the field of wood processing equipment, and specifically to an automatic single-sided woodworking contour milling machine. Background Technology

[0002] Currently, a type of comb with inlaid teeth is popular on the market. It consists of a comb back, comb teeth inserted into the comb back, and auxiliary teeth. The cross-section of the auxiliary teeth is rectangular. The side of the auxiliary teeth opposite to the comb teeth is flat, and the side of the auxiliary teeth away from the comb teeth has a curved profile. Since the auxiliary teeth are independent, in order to make effective use of wood resources, comb manufacturers usually first decompose and process the edge material into straight strip-shaped auxiliary teeth blanks with a length between 30mm and 50mm, a width between 8mm and 14mm, and a thickness between 6mm and 8mm. The blanks are of uniform specifications and have a rectangular cross-section. Then, the single-sided curved profile is processed. Finally, the auxiliary teeth blanks are assembled onto the comb back to complete the final polishing and shaping. The traditional method for processing single-sided curved surface features involves first manually drawing the required shape curve on the upper surface of the toothed blank, and then manually operating a woodworking wire saw to cut the required curved surface outline along the shape curve. Although the above processing method is flexible, it has low batch processing efficiency and the saw cut surface is not smooth. In addition, because the toothed blank is too small, the fingers that press and push the toothed blank during sawing are easily cut by the saw blade.

[0003] The currently popular automatic woodworking profiling equipment mainly consists of a stacking storage box, an automatic rotating template mechanism, a vertical pressing mechanism, a cutting spindle mechanism, and an automatic swing arm mechanism. Its structure and processing principle are as follows: the profiling template is fixed on the rotating seat of the automatic rotating template mechanism, the workpiece is placed on the profiling template, the vertical pressing mechanism is fixed above the frame, and the cutting spindle mechanism is mounted on a swing arm fixed to one corner of the frame. The swing arm is driven by a swing cylinder. A template bearing and a milling cutter are coaxially mounted on the cutting spindle. During processing, a pushing device pushes a workpiece from the bottom of the box onto the profiling template, the vertical pressing mechanism presses the workpiece firmly, and the template and workpiece of the automatic rotating template mechanism rotate synchronously and uniformly. The template bearing on the cutting spindle rolls against the working surface of the profiling template under the action of the swing arm. The cutter, coaxially mounted with the template bearing, processes the workpiece to create a contour consistent with the working surface of the profiling template. This type of automatic woodworking profiling equipment is mainly suitable for large wooden workpieces that require circumferential curved surface processing, such as wooden brush handles. This type of equipment is too large and complex to be suitable for processing small strip-shaped wooden workpieces with only a single curved surface profile. Summary of the Invention

[0034] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0035] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0036] This invention discloses an automatic single-sided woodworking contour milling machine.

[0037] Example 1: An automatic single-sided woodworking contour milling machine includes a frame 1, a feeding device 2, a feeding device 3, a pressing device 4, a milling device 5, a contouring device 6, and an automatic control device 7. The automatic control device 7 is used to control the operation of the contour milling machine. The feeding device 2 includes a vibrating feeding plate 21 and a feeding channel 22 disposed on one side of the frame 1. The feeding device 3 includes a feeding channel 31 and a pushing mechanism 32 disposed on the frame 1. The feeding channel 31 is connected to the feeding channel 22. A material picking position is provided at the outlet of the feeding channel 31. The pushing mechanism 32 is used to pick up the material. The workpiece is pushed from the milling position to the milling position. A discharge port 11 is located on one side of the milling position on the frame 1, and a dust extraction hood 15 is installed near the discharge port 11 on the frame 1. The pressing device 4 includes a pressing plate 41 and a pressing drive 42, which is a cylinder. The pressing drive 42 drives the pressing plate 41 to press the workpiece firmly onto the milling position. The milling device 5 includes a milling slide 51 mounted on the frame 1, a power milling head 52 mounted on one side of the milling slide 51, and a drive component 53 for moving the milling slide 51. A milling head 52 is mounted on the power milling head 52. The cutting tool and the driving component 53 are cylinders. The driving component 53 is used to drive the milling slide 51 to move so that the power milling head 52 can mill the workpiece. The contouring device 6 includes a contouring base 61 set on the frame 1 and a contouring template 62 set on the contouring base 61. The contouring template 62 is provided with a track groove 621. The milling slide 51 can be driven to move along the track groove 621 so that the power milling head 52 can mill the workpiece at the milling position. In use, the workpiece is placed in the vibrating feed plate 21, and the vibrating feed plate 21 moves the workpieces sequentially into the feeding channel 31. The process continues until the first workpiece moves to the picking position. The pushing mechanism 32 pushes the workpiece from the picking position to the milling position. At this time, the subsequent workpieces continue to move to the picking position. The pressing drive 42 drives the pressure plate 41 to press on the workpiece, fixing the workpiece in the milling position. The milling slide 51 is driven by the drive 53, causing the power milling head 52 to change direction and move to mill the workpiece. After the workpiece is milled, the pressure plate 41 is driven to release the workpiece, and the workpiece is pushed into the unloading port 11 to complete the milling. During the milling process, the dust suction hood 15 can suck away the dust generated, preventing the dust generated during the milling process from spreading everywhere.

[0038] In this embodiment, the feeding channel 31 includes a channel base plate 311, a baffle plate 312 disposed on the channel base plate 311, and a guide cover plate 313 disposed on the baffle plate 312. The baffle plate 312 includes a side stop block 3121, a front stop block 3122 and a rear stop block 3123 respectively disposed at both ends of the side stop block 3121. The front stop block 3122 and the rear stop block 3123 both extend toward the direction of the power milling head 52, and the extension length is less than the workpiece width. An open groove 3131 is provided on the bottom side of the guide cover plate 313. The width of the open groove 3131 is slightly larger than the width of a workpiece. The distance between the top surface of the open groove 3131 and the upper surface of the rear stop block 3123 is slightly larger than the thickness of a workpiece. The open groove 3131 is located above the rear stop block 3123 and forms a feeding groove with the rear stop block 3123. In order to facilitate the observation of the feeding status of the workpiece, an elongated observation hole 3133 is provided on the guide cover plate 313 along the length direction of the open groove 3131.

[0039] In this embodiment, the inner wall of the open groove 3131 on the side away from the milling slide 51 is aligned with the side wall of the side stop 3121, and the inner wall of the open groove 3131 on the side near the milling slide 51 is parallel to and opposite to the side wall of the rear stop 3123. The length of the open groove 3131 is greater than the length of the rear stop 3123, so that the guide cover 313 covers the rear stop 3123 by a certain distance in the direction of the front stop 3122. The shoulder surface of the open groove 3131 on the side near the milling slide 51 is aligned with the bottom of the channel. A gap, less than the height of the workpiece, is left between the plates 311 to form a material receiving port. A retaining spring 3132 is provided at the outlet of the open slot 3131. The retaining spring 3132 and the rear stop block 3123 form a material receiving position that can accommodate one workpiece. The lower edge of the retaining spring 3132 is opposite to the upper surface of the channel bottom plate 311 and forms a material outlet with a height slightly less than the thickness of one workpiece. The thickness of the retaining plate 312 is slightly thinner than the workpiece. The rear stop block 3123 is part of the retaining plate 312. The top surface of the workpiece at the picking position is higher than the surface of the rear stop 3123, so that the workpiece in the feed chute and the workpiece at the picking position abut each other end to end. The channel bottom plate 311 is located at the corner joint of the side stop 3121 and the front stop 3122 to form the milling position of the workpiece. The side wall of the side stop 3121 near the milling slide 51 is provided with a slot. The slot is provided with a discharge spring 3124 for pushing the milled workpiece into the discharge port 11. One end of the discharge spring 3124 is fixed in the slot. The other end is a free end. The free end of the unloading spring 3124 extends obliquely towards the side stop 3121 and the milling slide 51. The pushing mechanism 32 presses the workpiece against the side wall of the side stop 3121, causing the workpiece to move along the side wall of the side stop 3121. During the movement, the stop spring 3132 is pushed open to move the workpiece to the milling position. The unloading spring 3124 is pressed into the hole groove. After the milling is completed, the pressure plate 41 releases the workpiece, and the workpiece moves into the unloading port 11 under the elastic force of the unloading spring 3124.

[0040] In this embodiment, the pushing mechanism 32 includes a bracket 321, a cylinder 322 mounted on the bracket 321, a telescopic rod 323 slidably inserted into the cylinder 322, and a fork 324 located at the front end of the telescopic rod 323. A compression spring 327 is installed inside the cylinder 322, and a threaded plug 326 is installed at the tail end of the cylinder 322. Rotating the threaded plug 326 adjusts the spring force on the back of the telescopic rod 323. A long, narrow mounting hole is vertically opened along the bracket 321. An external thread is provided at the tail end of the cylinder 322. After passing through the mounting hole, the tail end of the cylinder 322 is fixed to the bracket 321 by a locking nut. The cylinder 322 can move up and down within the mounting hole to adjust the horizontal height of the fork 324. The rear end of the telescopic rod 323 abuts against the end of the compression spring 327. The side wall of the telescopic rod 323 is provided with a long anti-rotation groove 3231 along its own length direction. The side wall of the cylinder 322 is provided with an anti-rotation bolt 3221 that cooperates with the anti-rotation groove 3231, which can prevent the telescopic rod 323 from rotating in the bracket 321. The bracket 321 can be driven to move along the length direction of the stop plate 312 on the frame 1 to move the workpiece from the picking position to the milling position. When in use, drive the bracket 321 to move so that the fork 324 enters the picking position and presses the workpiece in the picking position against the side wall of the side stop 3121. Then drive the bracket 321 to change direction and push the workpiece to the milling position.

[0041] In this embodiment, the shift fork 324 includes a pressing arm 3241 and a pushing arm 3242. The pressing arm 3241 is disposed towards the front stop block 3122, and the pushing arm 3242 is disposed towards the rear stop block 3123. The pushing arm 3242 is inclined and the angle between it and the pressing arm 3241 is an obtuse angle. The front ends of the pressing arm 3241 and the pushing arm 3242 are rounded. An clearance angle is provided at the connection between the pressing arm 3241 and the pushing arm 3242. The pusher arm 3242 is hinged to the front end of the telescopic rod 323. An elastic element 325, which is a rubber band, connects the pusher arm 3242 and the cylinder 322. The sides of the pressure arm 3241 and the pusher arm 3242 that contact the workpiece are the working surfaces. In the free state where the shift fork 324 is not in contact with the workpiece, the shift fork 324 naturally deflects to the side of the rear stop block 3123 under the action of the rubber band. At this time, the working surface of the pressure arm 3241 extends obliquely relative to the feeding channel 31. The distance between the end of the pressure arm 3241 and the side wall of the side stop block 3121 is... When the distance between the push arm 3242 and the side wall of the side stop 31 is less than the width of a workpiece, the push arm 3242 retracts away from the feeding channel 31. The distance between the end of the push arm 3242 and the side wall of the side stop 3121 is greater than the width of a workpiece. In the material handling state, the distance between the front end of the push arm 3242 and the side stop 3121 is less than the width of a workpiece. The working surface of the push arm 3242 hooks onto the rear end of the workpiece. Under the action of the compression spring 327 on the back of the telescopic rod 323, the working surface of the pressing arm 3241 abuts against the outer side of the workpiece, causing the inner side of the workpiece to contact the side stop. The inner wall of block 3121 is fitted. By reasonably setting the length of the pressing arm 3241 and the pushing arm 3242, the angle between the working surfaces of the pressing arm 3241 and the pushing arm 3242, the deflection angle of the shift fork 324, the extension length of the cylinder 322, and the spring force of the compression spring 327 on the back of the telescopic rod 323, it can be ensured that the shift fork 324 can deflect as needed and apply appropriate pressure and sufficient thrust to the workpiece. The thickness of the shift fork 324 is less than the height of the picking port, so the shift fork 324 can pass smoothly through the picking port of the picking position.

[0042] In this embodiment, the pressing device 4 further includes an anvil 43 mounted on the frame 1. The end of the pressing plate 41 is provided with a pressing end 411, which spans over the feeding channel 31 and is suspended above the milling position. The center of gravity of the pressing plate 41 is offset at the end where the pressing drive member 42 is located. The pressing plate 41 is hinged to the frame 1 near the pressing end 411. The pressing drive member 42 is vertically mounted on the pressing plate 41 at the end away from the pressing end 411. The driving force of the pressing drive member 42... The moving end is equipped with a roller 44. When the pressing drive 42 is started, the driving end moves downward and the roller 44 abuts against the anvil 43, causing the pressing end 411 to move downward and press the workpiece on the milling position. The pressing end 411 of the pressure plate 41 is in the normally open state. When pressing, the cylinder rod extends and the roller 44 at the head of the cylinder rod presses against the roller anvil 43. The pressure plate 41 rotates around the hinge and the pressing end 411 of the pressure plate 41 moves downward to press the workpiece. When unloading, the cylinder rod retracts and the tail of the pressure plate 41 automatically droops down, and the pressing end 411 automatically lifts up to release the workpiece.

[0043] In this embodiment, a longitudinal slide 12 is provided on the frame 1 along the workpiece movement direction. A slide rail is provided on the frame 1 for the longitudinal slide 12 to slide on. The longitudinal slide 12 can be driven by a drive member 53 to move along the workpiece movement direction. A bracket 321 is installed on the side of the longitudinal slide 12 and can be moved by the drive member 53. A buffer 14, which is a hydraulic buffer, is provided on the frame 1 and is located on the movement path of the longitudinal slide 12. A transverse slide rail 13 is provided on the longitudinal slide 12 and is perpendicular to the longitudinal slide 12. A milling slide 51 is slidably mounted on the transverse slide rail 13. A template rod 54 is vertically provided on the side of the milling slide 51 away from the power milling head 52. A support 55 for mounting the template rod 54 is provided on the milling slide 51, and the bottom end of the template rod 54 is inserted into the track. During milling in slot 621, after receiving the clamping signal of the workpiece, the drive unit 53 drives the longitudinal slide 12 and the milling slide 51 to change direction and move towards the material pick-up position. The working surface of the push arm 3242 of the shift fork 324 first disengages from the rear end of the workpiece. Then, the working surface of the pressure arm 3241 of the shift fork 324 slides a distance along the outer side of the workpiece and also disengages from the workpiece. The template rod 54 moves along the track slot 621 towards the material pick-up position. The power milling head 52 moves from the front side of the milling position towards the material pick-up position and automatically completes the contour milling of the workpiece according to the shape of the track slot 621. The wood chips generated during milling are sucked away by the dust suction hood 15. After milling is completed, the power milling head 52 moves to the rear side of the milling position. After receiving the milling end signal, the pressure plate 41 is lifted by the pressure mechanism 4, the workpiece is released, and the unloading spring 3124 automatically ejects the workpiece towards the milling slide 51 and drops it into the unloading port 11 on the frame 1.

[0044] In this embodiment, the template rod 54 is rotatably disposed within the support 55, and a bearing is installed within the support 55, so that the template rod 54 can rotate when it comes into contact with the side wall of the track groove 621 during movement, thereby reducing the friction between the template rod 54 and the side wall of the track groove 621.

[0045] In this embodiment, the trajectory groove 621 divides the contour template 62 into two parts along the trajectory centerline. The distance between the two contour templates 62 is adjustable to adjust the width of the trajectory groove 621. By finely adjusting the distance between the two halves, the rolling clearance between the trajectory groove 621 and the working end of the template rod 54 can be adjusted, thereby reducing impact vibration during operation and improving the quality of the milled surface. The longitudinal length of the trajectory groove 621 is slightly greater than the stroke length of the drive member 53 to prevent the template rod 54 from colliding with the contour template 62 when the drive member 53 reaches the end of its stroke. The trajectory of the trajectory groove 621 includes a milling trajectory consistent with the machining contour and a cutting-in and cutting-out trajectory that extends smoothly along both ends of the milling trajectory.

[0046] Example 2 differs from Example 1 in that: the template rod 54 is slidably disposed within the support 55, and the support 55 is provided with fastening bolts for fixing the template rod 54. The bottom end of the template rod 54 is a truncated cone with a larger upper end and a smaller lower end. The contour template 62 is a single piece. The width of the trajectory groove 621 is located between the maximum and minimum diameters of the truncated cone of the template rod 54. By adjusting the height of the template rod 54, the movement gap between the template rod 54 and the trajectory groove 621 can be adjusted, thereby achieving the purpose of controlling the contour milling accuracy.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
