Description

Technical Field

[0001] This utility model is a stone cutting machine with a convenient saw blade replacement, belonging to the field of stone cutting machines. Background Technology

[0002] A stone cutting machine is a mechanical or electric tool specifically designed for cutting silicate materials such as stone and ceramic tiles.

[0003] The existing stone cutting machine uses a threaded connecting shaft that passes through the center of the saw blade flange and is connected to the connecting shaft by a nut or bolt. It is fixed by the positioning of the front and rear clamping plates of the saw blade. After long-term use, the spindle and the saw blade flange generate heat due to friction, causing metal expansion. After cooling, a micro-engagement is formed. When in contact with material chips or oil, the adhesion phenomenon is aggravated. During disassembly, it is often necessary to swing the saw blade left and right to facilitate the disassembly work. However, in this process, the connecting shaft is prone to wear, which affects the normal connection work. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a stone cutting machine with a convenient saw blade replacement mechanism.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides a technical solution for a stone cutting machine with convenient saw blade replacement: its structure includes a cutting platform 1, a cutting bracket 2, and a drive positioning component 3; the cutting bracket 2 is slidably mounted on the cutting platform 1; the drive positioning component 3 is slidably mounted on the cutting bracket 2, and a quick-release saw blade structure 36 is connected to the drive positioning component 3. The quick-release saw blade structure 36 includes a fixed clamping plate 361, a movable clamping plate 362, and a saw blade 363. The saw blade 363 is located between the fixed clamping plate 361 and the movable clamping plate 362. The end face of the fixed clamping plate 361 facing the saw blade 363 is provided with... The movable groove 3611 has a positioning plate 3612 enclosed at its opening. A sliding disk 3613 is horizontally slidable inside the movable groove 3611. Several top posts 3614 are arranged in a ring on the end face of the sliding disk 3613. The top posts 3614 movably penetrate the positioning plate 3612 and contact the saw blade 363. A return spring 3615 is provided between the middle of the other end face of the sliding disk 3613 and the inner wall of the movable groove 3611. The bottom surface of the fixed clamping plate 361 has an inclined structure that tilts the sliding disk 3613 so that it can slide horizontally.

[0019] To efficiently drive the saw blade 363 to rotate, the drive positioning assembly 3 includes a sliding positioning plate 31, a drive fixing plate 32, a cutting fixing plate 33, a rotating shaft 34, a driven wheel 35, a quick-release saw blade structure 36, a motor 37, and a drive wheel 38. The drive fixing plate 32 is horizontally connected to the upper front end of the sliding positioning plate 31, and the cutting fixing plate 33 is horizontally connected to the lower front end of the sliding positioning plate 31. The rotating shaft 34 is horizontally rotatably mounted on the upper surface of the cutting fixing plate 33. The driven wheel 35 is connected to one end of the rotating shaft 34, and the fixing clamp 361 is connected to the other end of the rotating shaft 34. The motor 37 is located on the upper end of the drive fixing plate 32, and the drive wheel 38 is connected to the output end of the motor 37 and is connected to the driven wheel 35 via a transmission belt.

[0020] In order to fix the saw blade 363, the positioning plate 3612 is attached to one side of the saw blade 363. The positioning plate 3612 has a screw 3618 that moves through the center of the saw blade 363 and the movable clamping plate 362. The movable clamping plate 362 is provided with a limiting nut 3621 that is threadedly connected to the screw 3618, so as to cooperate with the movable clamping plate 362 and the fixed clamping plate 361 to achieve the clamping and fixing of the saw blade 363.

[0021] In order to pre-position the saw blade 363, the fixed clamping plate 361 is provided with a number of positioning pins on the edge of the end face facing the saw blade 363, and the saw blade 363 is provided with slots that are compatible with the positioning pins.

[0022] For tilting transmission, the tilting structure includes a bolt groove 3616 located on the bottom surface of the fixed clamping plate 361. An adjusting bolt 3617 is threaded onto the bolt groove 3616. The top of the adjusting bolt 3617 extends into the movable groove 3611 and extends to form a conical structure that tilts into contact with the bottom of the sliding disk 3613. The outer wall of the sliding disk 3613 has a slope corresponding to the conical structure.

[0023] During operation, first unscrew the retaining nut 3621 from the screw 3618, then detach the movable clamping plate 362 to release the clamping restriction on the saw blade 363. Next, use a tool to screw the adjusting bolt 3617 into the movable groove 3611. During the screwing process, the conical structure on the adjusting bolt 3617 tilts against the slope of the sliding disc 3613. Figure 4 As shown, the sliding disc 3613 drives several top posts 3614 to push the saw blade 363, causing the saw blade 363 to break off from the part bonded to the screw 3618, so that the saw blade 363 can be quickly removed.

[0024] To prevent the sliding disk 3613 from tilting when acted upon by the top column 3614, the sliding disk 3613 and the saw blade 363 are located at the same center.

[0025] Since the top posts 3614 are arranged in a ring array, the top posts 3614 are also located at the same center as the saw blade 363. Under the pushing action of the top posts 3614, the saw blade 363 can move along the axial direction of the screw 3618, reducing the wear on the outer wall of the screw 3618.

[0026] In order to perform longitudinal cutting, the cutting bracket 2 has an arched structure. The left and right parts of the cutting bracket 2 are slidably connected to the two sides of the cutting platform 1, and the cutting platform 1 is provided with a first lead screw to drive the cutting bracket 2 to move back and forth.

[0027] In order to adjust the horizontal cutting position, the sliding positioning plate 31 is slidably connected to the front end of the crossbeam of the cutting bracket 2, and the cutting bracket 2 is provided with a second lead screw to drive the sliding positioning plate 31 to move horizontally left and right.

[0028] The first lead screw and the second lead screw are existing technologies, both including a lead screw body, a traveling part threadedly connected to the lead screw body, and a motor that drives the lead screw body to rotate. Example 2
