[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 This utility model provides a technical solution: a high-precision positioning work platform for electromagnetically shielded foamed PVC sheets, including an adjustable ruler 7 and a locking device. One end of the adjustable ruler 7 is rotatably connected to the cutting table 1 via a pin. The locking device is used to fix the ruler 7 to the cutting table 1 and lock the position of the other end of the adjustable ruler 7. The adjustable ruler 7 has an abutting edge that can abut against one edge of an item placed on the cutting table 1.
[0019] The electromagnetic shielded foamed PVC board high-precision positioning work platform provided in this embodiment is applicable to foamed PVC boards. When it is necessary to cut foam chamfered transition blocks of different specifications, the angle between the abutting edge of the adjustable ruler 7 and the cutting edge of the foam material is measured using an angle ruler. This angle is the cutting angle of the foam chamfered transition block. The adjustable ruler 7 is fixed with a locking device. One edge of the foam material to be cut is positioned by contacting the abutting edge of the fixed adjustable ruler 7, which will not cause angle deviation. At the same time, since one end of the adjustable ruler 7 is rotatably connected to the cutting table 1, it can also achieve multi-angle cutting. It is suitable for cutting the beveled edge of foam chamfered transition blocks of various specifications, reducing equipment resource investment and improving cutting efficiency.
[0020] Furthermore, the cut edge of the foam material is the edge of the foam material that is cut.
[0021] In one embodiment, the locking device can clamp and fix the adjustable ruler 7.
[0022] The locking device secures the adjustable ruler 7 by clamping. When the angle of the adjustable ruler 7 needs to be adjusted, the locking device is used to release it; when no adjustment is needed, the locking device is used to secure it.
[0023] In one embodiment, the locking device includes a clamping assembly and an adjustable member. The clamping assembly includes a first pressure plate 8 and a second pressure plate 9, which are distributed vertically and are both fixedly connected to the cutting table surface 1. An adjustable ruler 7 passes through the gap between the first pressure plate 8 and the second pressure plate 9. The adjustable member can adjust and lock the distance between the first pressure plate 8 and the second pressure plate 9 to release or clamp the adjustable ruler 7.
[0024] The adjustable ruler 7 is passed through the gap between the first pressure plate 8 and the second pressure plate 9, and the gap between the first pressure plate 8 and the second pressure plate 9 is adjusted using the adjustable component. This allows the adjustable ruler 7 to slide quickly and be fixed between the two, improving the efficiency of adjusting the angle between the adjustable ruler 7 and the first pressure plate 8. When it is necessary to change the angle of the adjustable ruler 7, the distance between the first pressure plate 8 and the second pressure plate 9 needs to be released using the adjustable component. After the adjustment is completed, the distance between the first pressure plate 8 and the second pressure plate 9 is clamped and fixed using the adjustable component.
[0025] In one embodiment, the two ends of the first pressure plate 8 are the first end and the second end, and the two ends of the second pressure plate 9 are the third end and the fourth end. The first end is used to be fixedly connected to the upper surface of the cutting table 1, and the third end is used to be fixedly connected to the first side of the cutting table 1. The second end and the fourth end both extend out of the cutting table 1. One end of the adjustable ruler 7 is attached to the upper surface of the cutting table 1 and rotates around the vertical axis. The other end of the adjustable ruler 7 passes through the gap between the second end and the fourth end. The adjustable member can adjust and lock the distance between the second end and the fourth end.
[0026] The first end is fixedly connected to the upper surface of the cutting table 1, the third end is fixedly connected to the first side of the cutting table 1, and the second and fourth ends both extend out of the cutting table 1. This arrangement allows the adjustable ruler 7 to remain straight as it passes through the gap between the first pressure plate 8 and the second pressure plate 9. This means that the entire adjustable ruler 7 is always located on the upper surface of the cutting table 1, and even the part that leaves the cutting table 1 is always parallel to its upper surface, preventing bending that would prevent it from touching the item.
[0027] In one embodiment, the edges of the first pressure plate 8 and the second pressure plate 9 near the cutting blade 2 are parallel to the projection of the cutting blade 2 onto the cutting table 1.
[0028] The angle formed by the projection of the cutting blade 2 onto the cutting table 1 and the adjustable ruler 7 is angle one, and the angle formed by the adjustable ruler 7 and the first pressure plate 8 is angle two. Angle one and angle two are complementary, which makes it easy to calculate angle two, and also makes it easy to measure the angle and determine the position of the adjustable ruler 7 on the first pressure plate 8.
[0029] In one embodiment, the adjustable component includes a disc-shaped knob 10, with coaxial through holes at the second and fourth ends, and the disc-shaped knob 10 is threaded into the through holes.
[0030] Coaxial perforation means that the centers of the threaded holes at the second and fourth ends are perfectly aligned. When the disc-shaped knob 10 passes through the two perforations, its axis is consistent with the force direction of the first pressure plate 8 and the second pressure plate 9. When the knob is rotated, the threaded drive will cause the second and fourth ends to move closer or further away synchronously along the axial direction, thereby making the distance between the first pressure plate 8 and the second pressure plate 9 change evenly. This prevents the pressure plates from tilting to one side due to misalignment of the perforations, ultimately ensuring uniform vertical clamping of the adjustable straightedge 7 and avoiding local loosening or deformation of the straightedge due to pressure plate tilt, indirectly improving cutting positioning accuracy. Furthermore, the disc-shaped knob 10 can be operated by hand, simplifying the operation steps and reducing time costs.
[0031] In one embodiment, the adjustable component includes a disc-shaped knob 10 and a threaded portion fixedly disposed on the lower side of the disc-shaped knob 10. The upper surfaces of the second and fourth ends are provided with coaxial screw holes. The threaded portion of the disc-shaped knob 10 is threadedly connected to the screw hole. The thread directions on the upper and lower sides of the threaded portion are opposite, and the thread directions of the screw holes on the second and fourth ends are also opposite. In this way, when the threaded portion is rotated by the disc-shaped knob 10, the opposite threads at both ends can make the first pressure plate 8 and the second pressure plate 9 move synchronously towards or away from each other, thereby making the distance between the first pressure plate 8 and the second pressure plate 9 change uniformly.
[0032] An anti-slip pad is provided on the surface between the second and fourth ends. The anti-slip pad can improve the friction and at the same time protect the surface of the adjustable ruler 7.
[0033] In one embodiment, the adjustable ruler 7 has a groove 12 along its length, the extension direction of the groove 12 is parallel to the abutment edge, and a positioning post 11 is slidably connected to the groove 12.
[0034] The extension direction of the slide groove 12 is parallel to the abutment edge, which facilitates the sliding of the positioning post 11 on the slide groove 12. When the angle of the adjustable ruler 7 is measured by the angle ruler, the positioning post 11 is slid on the slide groove 12 to contact the first pressure plate 8 and make a mark on the first pressure plate 8. When the angle is used for cutting again, the positioning post 11 is simply slid on the slide groove 12 until it contacts the first pressure plate 8 and is located at the marked position.
[0035] In one embodiment, a fixed shaft 3 is fixedly installed on the cutting table 1 at one end away from the locking device. The axis of the fixed shaft 3 is horizontal, and a cutting blade 2 is rotatably installed on the outside of the fixed shaft 3. The cutting blade 2 can cut the items placed on the cutting table 1 by rotating around the fixed shaft 3 toward the cutting table 1.
[0036] In this embodiment, the item to be cut is placed on the cutting table 1, and the adjustable ruler 7 and locking device are used to hold the item in place. After the cutting angle is determined, the cutting blade 2 is used to cut the item by facing the cutting table 1. The cutting method of the cutting blade 2 can improve the cutting efficiency of the item, shorten the single-piece cutting time, improve the processing efficiency, and adapt to mass production.
[0037] In one embodiment, the cutting blade 2 is rotatably connected to the cutting table 1, and the cutting blade 2 can rotate toward the cutting table 1 in a first direction to cut the item placed on the cutting table 1.
[0038] The cutting blade 2 is rotatably connected to the cutting table 1, making it convenient to use and reducing safety risks.
[0039] In one embodiment, it also includes an anti-slip pressure plate 6, which is rotatably connected to the fixed axis 3 and can press the item placed on the cutting table 1 after rotating around the first direction, thereby improving the stability and processing accuracy during cutting.
[0040] The fixed axis 3 can be used to mount the cutting blade 2, facilitating the rotatable connection between the cutting blade 2 and the cutting table 1. The cutting blade 2 is mechanically linked through the fixed axis 3, making it convenient to use and reducing safety risks. The fixed axis 3 is fixed to the first side of the cutting table 1 and movably connected to the cutting blade 2, providing rotational support for the cutting blade 2. It adapts to the cutting needs of beveled edges of foam chamfered strips of various specifications, improving cutting production efficiency. The anti-slip pressure plate 6 is rotatably connected to the fixed axis, and after rotating around the first direction, it can press down on the items placed on the cutting table to prevent slippage during cutting.
[0041] In one embodiment, the cutting knife 2 includes a handle 4 and a blade 5. The first end of the blade 5 is rotatably connected to a fixed shaft 3, and the second end of the blade 5 is fixedly connected to the handle 4. The operator holds the handle 4 to drive the blade 5 to rotate around a first direction and cut the item.
[0042] The handle 4 is for the operator to hold, and the blade 5 can cut items. It is simple to operate and easy to use.
