Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood technology, and in particular to a positioning tool for grooving the end face of plywood. Background Technology
[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with the fiber directions perpendicular to each other.
[0003] In current plywood production, when sealing the edge of the plywood end face or installing other components, it is necessary to cut grooves on the end face. In the prior art, the installation groove is usually machined on the end face of the plywood by hand with a drill bit. However, due to the vibration of the drill bit, the machined installation groove may be skewed, resulting in large processing errors, poor quality, and low efficiency. Therefore, this application discloses a positioning fixture for machining the end face groove of plywood. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a positioning fixture for grooving the end face of plywood.
[0005] This utility model is achieved through the following technical solution: a positioning fixture for grooving the end face of plywood, including a support frame, a table plate laid flat on the support frame, waist holes spaced apart and passing through the rear end of the table plate, flat stop strips installed on the waist holes, several pad strips spaced apart on the front side of the waist holes, a rotating stop strip is hinged to the end of the flat stop strip away from the edge of the table plate by bolts, a stepped elongated hole is provided through the rotating stop strip, the stepped elongated hole is rotatably connected to the arc-shaped groove by bolts, one end of a screw rod is rotatably connected to the rear side of the flat stop strip, the screw rod is threaded through and connected to the support block, and the support block is connected to the rear side of the support frame.
[0006] As a further improvement to the above solution, the arc-shaped groove is provided on the platform and located on the outside of the pad strip;
[0007] The rotatable and adjustable stop bar is fixed by using an arc-shaped groove, and the stop bar can move back and forth along with the flat stop bar through the arc-shaped groove and the waist hole.
[0008] As a further improvement to the above solution, a step is provided at one end of the flat stop bar, the flat stop bar is engaged with the end of the rotating stop bar by the step, and a stop is provided on the outside of the step;
[0009] The flat stop bar and the rotating stop bar are connected by hinges, and the translation achieves linkage. In addition, the stop on the outside of the step prevents the rotating stop bar from rotating to the outside, which limits the rotation angle of the rotating stop bar and ensures the effectiveness of the rotation angle of the rotating stop bar.
[0010] As a further improvement to the above solution, the outer end of the lead screw is connected to the handle rod.
[0011] The screw is rotated by the handle, causing it to move on the support block, which in turn moves the flat stop bar on the waist hole, ensuring accurate displacement of the flat stop bar.
[0012] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The end of the plywood is placed by a pad strip, and the end face of the plywood is blocked by a flat stop strip to limit the groove opened on the end face of the plywood, ensuring the accurate length of the groove. At the same time, the flat stop strip can be moved back and forth to adjust the length of the groove. The rotating stop strip is rotatably set to facilitate the opening of the inclined groove on the end face of the plywood. The inclined groove displacement can be adjusted with the waist hole, and the arc groove limits the angle of the rotating stop strip to adjust the inclination angle of the inclined groove.

[0015] Figure 3 This is a schematic diagram of the structure of the rotating connection between the flat stop bar and the rotating stop bar. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 As shown, a positioning fixture for grooving the end face of plywood includes a support frame 1, on which a platform 2 is laid flat. Waist holes 3 are provided at intervals and through the rear end of the platform 2. Flat stop strips 4 are installed on the waist holes 3. Several pad strips 10 are provided at intervals on the front side of the waist holes 3. One end of the flat stop strip 4 away from the edge of the platform 2 is hinged to a rotating stop strip 6 by bolts. A step 5 elongated hole 7 is provided through the rotating stop strip 6. The step 5 elongated hole 7 is rotatably connected to an arc-shaped groove 9 by bolts 8, that is, the step 5 elongated hole 7 rotates and slides on the arc-shaped groove 9. One end of a screw rod 12 is rotatably connected to the rear side of the flat stop strip 4. The screw rod 12 is threadedly connected to a support block 11. The support block 11 is connected to the rear side of the support frame 1.
[0018] As a further improvement to the above solution, the arc-shaped groove 9 is provided on the platform 2 and located on the outside of the pad strip 10;
[0019] The rotatable and adjustable stop bar 6 is fixed by the arc groove 9, and the stop bar 6 can move back and forth with the flat stop bar 4 through the arc groove 9 and the waist hole 3.
[0020] As a further improvement to the above solution, a step 5 is provided at one end of the flat stop bar 4, and the flat stop bar 4 is engaged with the end of the rotating stop bar 6 through the step 5, and a stop 14 is provided on the outside of the step 5;
[0021] The flat stop bar 4 and the rotating stop bar 6 are connected by hinges, and the translation achieves linkage. In addition, the stop bar 14 on the outside of the step 5 prevents the rotating stop bar 6 from rotating to the outside, which limits the rotation angle of the rotating stop bar 6 and ensures the effectiveness of the rotation angle of the rotating stop bar 6.
[0022] As a further improvement to the above solution, the outer end of the lead screw 12 is connected to the handle 13.
[0023] Rotate the lead screw 12 using the handle 13 to move the lead screw 12 on the support block 11, which in turn drives the flat stop bar 4 to move on the waist hole 3, ensuring that the flat stop bar 4 moves accurately.
[0024] The working principle of a positioning fixture for grooving the end face of plywood is as follows: the end face of the plywood is placed on the pad strip 10, and the end face of the plywood is blocked by the flat stop strip 4 to limit the groove opened on the end face of the plywood, ensuring the accurate length of the groove. At the same time, the flat stop strip 4 is moved back and forth to adjust the length of the groove. Meanwhile, the rotating stop strip 6 is rotatably set to facilitate the opening of the inclined groove on the end face of the plywood. The inclined groove displacement can be adjusted with the waist hole 3, and the arc groove 9 limits the angle of the rotating stop strip 6 to adjust the inclination angle of the inclined groove.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
