Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an angle adjustment structure for a brick cutter. Background Technology

[0002] A bricklaying cutting machine is a specialized device used in masonry projects to cut building materials such as bricks and stones. It is a process that precisely cuts bricks to a predetermined size and shape to meet the product's requirements for size, shape, and appearance quality.

[0003] Currently, a common problem in brick cutting operations is that operators typically need to manually adjust the brick angle to achieve the desired cutting position. This manual adjustment is not only inefficient but also prone to inaccurate angle adjustments due to human factors, thus affecting the cutting accuracy and the final quality of the bricks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an angle adjustment structure for a brick cutter, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle adjustment structure for a brick cutter, including a support frame; A pressure rod is hinged to the right side of the top of the support frame via a hinge shaft. A sliding sleeve is slidably connected to the outer side of the pressure rod. A vertical rod is provided through the inner top wall of the support frame. The top end of the vertical rod is hinged to the sliding sleeve via a hinge shaft. The bottom end of the vertical rod is fixed with an upper cutter by bolts, and corresponding to the upper cutter, a lower cutter is fixed with bolts on the inner bottom wall of the support frame; The support frame is provided with a mounting base on the front side, and a rotating shaft is rotatably connected inside the mounting base. A placement plate for placing bricks is fixedly sleeved on the outside of the rotating shaft. A guide assembly is installed on the front side of the support frame. The guide assembly includes an arc-shaped guide rod installed on the front side of the support frame. A connecting block is installed on the lower surface of the placement plate. The connecting block is slidably connected to the outside of the arc-shaped guide rod. A fixing component is also installed on the placement plate for securing the bricks.

[0006] Furthermore, the arc-shaped guide rod is semi-circular in shape, and the connecting block has an arc-shaped through hole inside that matches the arc-shaped guide rod.

[0007] Furthermore, the circle of the arc-shaped guide rod and the center of the rotating shaft are located on the same vertical line.

[0008] Furthermore, a fastening bolt with one end penetrating through and extending into the arc-shaped through hole is threaded onto the front side of the connecting block, and one end of the fastening bolt abuts against the arc-shaped guide rod.

[0009] Furthermore, the fixing assembly includes a frame fixed to both sides of the placement plate by bolts, a screw threaded to the inner top wall of the frame, a pressure plate slidably connected between the left and right sides of the inner wall of the frame, and the screw and the pressure plate rotatably connected by bearings.

[0010] Furthermore, a guide rod is vertically installed on both the left and right sides of the upper surface of the lower pressure plate; Corresponding to the two guide rods, two through holes are opened on the inner top wall of the frame, each allowing the two guide rods to pass through.

[0011] Furthermore, the lower surface of the pressure plate is serrated.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-4 In this embodiment, a brick cutter uses an angle adjustment structure to adjust and fix the angle at which the bricks are cut. Specifically, it includes a support frame 1, a lower pressure rod 2, a sliding sleeve 3, a vertical rod 4, an upper cutter 5, a lower cutter 6, a mounting base 7, a rotating shaft 8, a placement plate 9, a guide assembly 10, and a fixing assembly 11.

[0018] The support frame 1 is a frame-type metal structure. The lower pressure rod 2 is connected to the top right side of the support frame 1 through a hinge shaft and can rotate up and down around the hinge shaft. A sliding sleeve 3 is sleeved on the outside and can slide along the outside of the lower pressure rod 2. The vertical rod 4 passes through the through hole in the inner top wall of the support frame 1. The top end is connected to the sliding sleeve 3 through a hinge shaft, and the bottom end is fixed with an upper cutter 5 by bolts. The upper cutter 5 is made of alloy steel. The lower cutter 6 is fixed to the inner bottom wall of the support frame 1 by bolts, corresponding to the upper cutter 5, and the blades of both are in the same direction.

[0019] In actual use, the hinged connection between the support frame 1 and the lower pressure rod 2 allows the lower pressure rod 2 to rotate around the hinge axis, providing a power transmission basis for the cutting action; the sliding connection between the sliding sleeve 3 and the lower pressure rod 2, together with the hinge between the sliding sleeve 3 and the vertical rod 4, can convert the rotational motion of the lower pressure rod 2 into the vertical up-and-down motion of the vertical rod 4, ensuring the stable lifting and lowering of the upper cutter 5 and avoiding deviation during cutting.

[0020] Furthermore, the mounting base 7 is welded to the middle of the front side of the support frame 1, and a rotating shaft 8 is rotatably connected inside via a bearing. The rotating shaft 8 is set in the horizontal direction. The placement plate 9 is a rectangular metal plate, which is fixedly sleeved on the outside of the rotating shaft 8 and is used to place the bricks to be cut. The guide assembly 10 is installed between the front side of the support frame 1 and the placement plate 9 and is used to guide the rotation of the placement plate 9. The fixing assembly 11 is installed on both sides of the upper surface of the placement plate 9 and is used to clamp the bricks.

[0021] In addition, the bolted connection between the vertical rod 4 and the upper cutter 5 facilitates the disassembly and replacement of the upper cutter 5. The fixed connection between the lower cutter 6 and the support frame 1 forms an upper-lower correspondence with the upper cutter 5. The brick cutting is achieved through the shearing action of the two. The bolted connection also facilitates the maintenance and replacement of the lower cutter 6.

[0022] In detail, the guide assembly 10 includes an arc-shaped guide rod 1001 and a connecting block 1002. The arc-shaped guide rod 1001 is a semi-circular metal rod with both ends fixed to the front side of the support frame 1. Its center coincides with the center of the rotating shaft 8. The connecting block 1002 is welded to the lower surface of the placement plate 9 and has an arc-shaped through hole inside that matches the arc-shaped guide rod 1001. The connecting block 1002 is sleeved on the outside of the arc-shaped guide rod 1001 and can slide along it. The front side of the connecting block 1002 is threaded with a fastening bolt 1003. Tightening the fastening bolt 1003 can fix the connecting block 1002 to the arc-shaped guide rod 1001.

[0023] In actual setup, the arc-shaped guide rod 1001 provides trajectory constraints for the rotation of the placement plate 9. At the same time, the sliding connection between the connecting block 1002 and the arc-shaped guide rod 1001 can guide the placement plate 9 to rotate stably along the arc trajectory, avoiding shaking during rotation. After adjustment, tightening the fastening bolt 1003 can fix the position of the placement plate 9 after the angle adjustment is completed, ensuring angle stability during cutting.

[0024] In addition, in actual setup, to enable operators to more accurately and intuitively control the cutting angle of the bricks, equidistant scale grooves (not shown in the figure) can be opened on the outer side of the arc-shaped guide rod 1001 along its arc direction. The value of the scale groove corresponds to the rotation angle of the placement plate 9. When the placement plate 9 is pushed to drive the connecting block 1002 to slide along the arc-shaped guide rod 1001, the operator can directly read the current rotation angle of the placement plate 9 by the corresponding position of the edge of the connecting block 1002 and the scale groove of the arc-shaped guide rod 1001.

[0025] In more detail, the fixing component 11 includes a frame 1101, a screw 1102, a lower pressure plate 1103, and a guide rod 1104. The frame 1101 is an inverted U-shaped metal frame, which is fixed to both sides of the upper surface of the placement plate 9 by bolts. The screw 1102 passes through the threaded hole in the inner top wall of the frame 1101, and a knob is welded to the top end. The bottom end is connected to the lower pressure plate 1103 through a bearing. The lower pressure plate 1103 is a rectangular metal plate that is slidably connected to both sides of the inner wall of the frame 1101. The lower surface is serrated. The guide rod 1104 is vertically welded to both sides of the upper surface of the lower pressure plate 1103. The top end passes through the through hole in the inner top wall of the frame 1101 and can slide along it.

[0026] In actual setup, the screw 1102 and the frame 1101 are connected by a thread, so that the screw 1102 can drive the lower pressure plate 1103 to move up and down when rotating in both directions, thereby realizing the clamping and releasing operation of the brick. At the same time, the sliding connection between the lower pressure plate 1103 and the frame 1101, together with the guiding action of the guide rod 1104, can ensure that the lower pressure plate 1103 always maintains a vertical lifting state, effectively avoiding the problem of unstable clamping caused by tilting. Moreover, the serrated design on the lower surface of the lower pressure plate 1103 can also increase the friction between it and the brick, further preventing the brick from sliding during the cutting process.

[0027] The working principle of the above embodiments is as follows: (1) According to the required cutting angle of the brick, loosen the fastening bolt 1003 of the guide assembly 10 and push the placement plate 9 to rotate around the rotating shaft 8. At this time, the connecting block 1002 slides along the arc guide rod 1001 until the placement plate 9 rotates to the target angle. Then tighten the fastening bolt 1003 to fix the connecting block 1002 and the arc guide rod 1001 to complete the angle adjustment. Place the brick to be cut on the upper surface of the placement plate 9, rotate the screw 1102 knob of the fixing assembly 11 to drive the lower pressure plate 1103 to move down along the inner wall of the frame 1101. The guide rod 1104 slides down and keeps the lower pressure plate 1103 horizontal until the serrations on the lower surface of the lower pressure plate 1103 are in close contact with the surface of the brick to complete the brick fixing.

[0028] (2) Press down the lower pressure rod 2. The lower pressure rod 2 rotates around the hinge axis with the support frame 1, pushing the sliding sleeve 3 to slide along the lower pressure rod 2 and driving the vertical rod 4 to move vertically downward. The upper cutter 5 descends with the vertical rod 4 and works with the lower cutter 6 to cut the bricks and complete the cutting. After the cutting is completed, release the lower pressure rod 2. Under the action of the device's own gravity or the return spring, the upper cutter 5 rises back to the initial position.
