[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-5As shown, the utility model proposes a furniture edge grinding machine, including a guide rail frame 1, a guide rail table 2 slidably arranged on the guide rail frame 1, and a sharpener 3 arranged on one side of the guide rail table 2. The sharpener 3 is connected through an external fixing part and can be raised, lowered, rotated and adjusted. Since it is a prior art, it is not fully shown in the figure.

[0033] In this embodiment, the furniture edge grinding machine includes an extrusion type rotating mechanism 4 for allowing a circular workpiece 5 to contact and grind the edge of a grinding knife 3 in a horizontally rotating manner, and the extrusion type rotating mechanism 4 includes a base 41, a rotating table 42, a vertical bar arm 43, a vertical screw shaft 44, a stop block 45 and a first rotating handle 46. Specifically, the rotating table 42 is coaxially arranged with the base 41, and a T-shaped rotating shaft is fixedly connected to the bottom of the rotating table 42, and a T-shaped rotating groove matching the T-shaped rotating shaft is provided on the upper surface of the base 41, and the T-shaped rotating shaft rotates horizontally in the T-shaped rotating groove about the central axis of the base 41 and the rotating table 42. The bottom end of the vertical bar arm 43 is fixedly connected to the outer annular surface of the base 41, and the top end of the vertical bar arm 43 is threadedly screwed to the vertical screw shaft 44, the bottom end of the vertical screw shaft 44 is rotatably sleeved to the stop block 45, and the first rotating handle 46 is fixedly connected to the stop block 45. The circular workpiece 5 is placed on the rotating table 42, and after being centered by the centering positioning mechanism 6 described below, the vertical screw shaft 44 is rotated, and the vertical screw shaft 44 moves downward through the threaded engagement with the vertical bar arm 43, so that the stop block 45 abuts against the upper surface of the circular workpiece 5. Therefore, when the first rotating handle 46 is held and rotated, the circular workpiece 5 can be driven to rotate horizontally through the friction contact between the stop block 45 and the circular workpiece 5. When rotating, its edge contacts the grinding knife 3, thereby achieving edge grinding;

[0034] Furthermore, the furniture edge grinding machine also includes a centering positioning mechanism 6 for centering the circular workpiece 5, and the centering positioning mechanism 6 includes a slide 61, a positioning arm 62, a slider 63, a first screw shaft 64 and a scale line 65. There are three slides 61 in total, and they are fixedly connected to the outer ring surface of the base 41 in a circular array. The top of the positioning arm 62 contacts the outer ring surface of the circular workpiece 5, and the bottom of the positioning arm 62 is fixedly connected to the slider 63. The slide 61 is provided with a slot for the slider 63 to slide horizontally, and the first screw shaft 64 is rotatably connected to both ends of the slot, and the first screw shaft 64 is threadedly screwed and sleeved with the slider 63. In addition, the scale line 65 provided on the upper surface of the slide 61 is used to indicate the translation distance of the positioning arm 62. Specifically, after placing the circular workpiece 5 on the base 41, each first screw shaft 64 is rotated, and each positioning arm 62 is driven to move horizontally through the threaded engagement between the first screw shaft 64 and the slider 63, so that the three positioning arms 62 are respectively attached to the outer ring surface of the circular workpiece 5 (not tightly, so as to avoid the circular workpiece 5 being unable to rotate), and ensure that each positioning arm 62 is located at the same scale of the scale line 65, so that the circular workpiece 5 is centered. In other embodiments, a linkage structure can also be designed to allow the three positioning arms 62 to move simultaneously, which will not be described in detail here.

[0035] Furthermore, the furniture edge grinding machine also includes a distance-adjusting and rotating mechanism 7, which is used to allow circular workpieces 5 of different diameters to contact the grinder 3 and rotate the extrusion-type rotating mechanism 4 and the centering positioning mechanism 6 away from the top of the guide rail table 2 to facilitate the edge grinding of strip-shaped workpieces. The distance-adjusting and rotating mechanism 7 includes a fixed table 71, a rotating table 72, a fixed vertical plate 73, a second screw shaft 74, a connecting plate 75, a second rotating handle 76 and a rotating handle limit block 77. The fixed table 71 is fixedly connected to the front edge surface of the guide rail table 2. The front end of the fixed table 71 is rotatably connected to the front end of the rotating table 72 via a vertical rotating shaft. When it is necessary to use the traditional method to grind the strip-shaped workpiece, the above-mentioned structures can be connected as follows. Figure 4 As shown, it is rotated away from the top of the guide rail platform 2. The top of the connecting plate 75 is fixedly connected to the bottom of the slide 61, and a slider is arranged at its bottom, and the slider is slidably connected to the slide groove provided on the rotating table 72. The rear end of the second screw shaft 74 is rotatably connected to the connecting plate 75, and the front upper surface of the rotating table 72 is fixedly connected with a fixed vertical plate 73, and the fixed vertical plate 73 is threadedly engaged with the second screw shaft 74. Specifically, when the second screw shaft 74 is rotated, the second screw shaft 74 translates through the threaded engagement with the fixed vertical plate 73, and then pushes the slide 61 to translate through the connecting plate 75, that is, pushes the centering positioning mechanism 6, the extrusion type rotating mechanism 4, and the circular workpiece 5 to translate as a whole. When the diameter of the circular workpiece 5 is small, it can translate as a whole in the direction close to the grinder 3, so that the edge surface of the circular workpiece 5 can contact the grinder 3, otherwise it translates in the direction away from the grinder 3.

[0036] In addition, one end of the second rotating handle 76 is fixedly connected to the edge surface of the rotating table 72, and a pair of rotating handle stop blocks 77 are provided, which are respectively fixedly connected to two adjacent edge surfaces of the fixed table 71. The second rotating handle 76 can correspond vertically to a single rotating handle stop block 77, and the rotating handle stop block 77 and the second rotating handle 76 are both provided with a through hole for the pin to vertically pass through. Figure 1 and Figure 4 As shown, when the second rotary handle 76 is located above the guide rail platform 2 and rotated away from the guide rail platform 2, it will be vertically aligned with the rotary handle limit blocks 77 at different positions and can be limited in series by the pin shaft.

[0037] The working principle of this embodiment is as follows: through the design of the extrusion type rotating mechanism 4, the circular workpiece 5 can be edged by rotation; the circular workpiece 5 can be centered by the centering positioning mechanism 6, which is convenient for the above-mentioned rotation action; the circular workpieces 5 of different diameters can be brought into contact with the grinder 3 for edge grinding by the adjustable distance rotation mechanism 7, and at the same time, the above-mentioned structures can be removed from the top of the guide rail table 2 to avoid obstruction to the edge grinding action of the strip workpiece.

[0038] Place the circular workpiece 5 on the rotating table 42, and after the centering is processed by the centering positioning mechanism 6, rotate the vertical screw shaft 44 so that the stop block 45 is pressed against the center of the upper surface of the circular workpiece 5. Rotate the second screw shaft 74 to adjust the position of the circular workpiece 5 so that the edge surface of the circular workpiece 5 can contact the grinder 3. Hold the stop block 45 and rotate it, driving the circular workpiece 5 to rotate, so that the edge surface of the circular workpiece 5 contacts the grinder 3 in a circular path to perform the edge grinding operation. When the edge grinding process needs to be changed to strip workpiece edge grinding, the second rotating handle 76 can be held to turn the entire device from Figure 1 The status shown rotates to Figure 4 State, place the strip workpiece to be edged on the guide rail table 2 for edge grinding operation. Since edge grinding of strip workpieces is a prior art, it will not be described in detail here.

[0039] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
