Description

Technical Field

[0001] This invention relates to the field of slicing and processing hard and brittle materials, and more particularly to a grooved wheel removal device for a multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines are a new type of high-efficiency and high-precision cutting equipment. Through the high-speed reciprocating motion of diamond wires, the workpiece is fixed on the cutting table and fed in, gradually cutting the workpiece into hundreds or thousands of thin slices simultaneously. Multi-wire cutting machines are widely used in the slicing of hard and brittle materials due to their high efficiency and precision. However, multi-wire cutting machines have multiple grooved rollers. When replacing these rollers, due to their weight, different positions, and the presence of a bolt inside each roller, disassembly requires two people and can only remove one roller at a time, significantly impacting efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a grooved wheel disassembly device for a multi-wire cutting machine, so as to solve the problem of low disassembly efficiency of the grooved wheel due to its large weight, different position height and internal spindle, and to meet the requirements of safe and quick disassembly of the grooved wheel.

[0004] The technical means employed in this invention are as follows:

[0005] A grooved wheel removal device for a multi-wire cutting machine includes a device body, a spring stop block, and a bolt fixing block; one end of the grooved wheel of the multi-wire cutting machine is mounted to the machine frame by a grooved wheel bolt.

[0006] The main body of the device has a hexagonal hole along the axial direction and a spring stop mounting hole connected to the hexagonal hole along the radial direction; the hexagonal hole is coaxial with the grooved wheel and the opening faces the grooved wheel; one end of the main body of the device is fixedly installed on the frame, and the other end is equipped with a side-opening cover for covering the hexagonal hole;

[0007] The bolt fixing block is a hexagonal prism structure that matches the hexagonal hole; the bolt fixing block is located inside the hexagonal hole, with a groove at one end that matches the shape of the grooved wheel bolt, and a spring installed between the other end and the side opening cover;

[0008] The spring stop includes a stop block and a stop spring; one end of the stop block is provided with a limit block and the other end is provided with a pull block. The limit block and the pull block are connected by a shaft. The pull block is located outside the spring stop mounting hole. The limit block and the shaft extend into the interior of the device body through the spring stop mounting hole. The stop spring is sleeved on the shaft, with one end in contact with the end face of the limit block and the other end in contact with the side wall of the spring stop mounting hole. The limit block is used to extend into the hexagonal hole to limit the bolt fixing block.

[0009] Furthermore, the hexagonal hole is coaxial with the grooved wheel bolt, and the opening faces the grooved wheel bolt.

[0010] Furthermore, the main body of the device includes a base; the base is coaxial with the grooved wheel, the base is fixedly installed on the frame by bolts, and the spring stop block mounting hole is located on the base.

[0011] Furthermore, one side of the side-opening cover is installed to the main body of the device via a movable hinge, and the other side is fitted with a latch between itself and the main body of the device.

[0012] Furthermore, when the limiting block extends into the hexagonal hole above the bolt fixing block to limit its movement, the spring is in a compressed state.

[0013] Furthermore, the pull block is used to pull the limiting block back into the spring stop mounting hole.

[0014] Furthermore, the bottom of the bolt fixing block and the limiting block are provided with mutually matching inclined surfaces. After the bolt fixing block pops out, the bottom of the bolt fixing block and the inclined surface of the limiting block cooperate with each other to prevent the bolt fixing block from retracting.

[0015] Furthermore, both the bolt fixing block and the side opening cover are provided with circular protrusions for installing the spring.

[0033] Example 1

[0034] like Figure 1-4 As shown, the present invention provides a grooved wheel disassembly device for a multi-wire cutting machine, including a device body 3, a spring stop 4, and a bolt fixing block 5; one end of the grooved wheel 2 of the multi-wire cutting machine is mounted to the frame 1 by a grooved wheel bolt;

[0035] The main body 3 of the device has a hexagonal hole along the axial direction and a spring stop block mounting hole that communicates with the hexagonal hole along the radial direction; the hexagonal hole is coaxial with the grooved wheel 2 and the opening faces the grooved wheel 2; one end of the main body 3 of the device is fixedly installed on the frame 1, and the other end is equipped with a side-opening cover 3-2 for covering the hexagonal hole;

[0036] The bolt fixing block 5 is a hexagonal prism structure that matches the hexagonal hole; the bolt fixing block 5 is located inside the hexagonal hole, with a groove at one end that matches the shape of the grooved wheel bolt, and a spring 3-4 installed between the other end and the side opening cover 3-2;

[0037] The spring stop 4 includes a stop 4-1 and a stop spring 4-2; one end of the stop 4-1 is provided with a limit block and the other end is provided with a pull block. The limit block and the pull block are connected by a shaft. The pull block is located outside the spring stop mounting hole. The limit block and the shaft extend into the device body 3 through the spring stop mounting hole; the stop spring 4-2 is sleeved on the shaft, one end of which contacts the end face of the limit block and the other end of which contacts the side wall of the spring stop mounting hole; the limit block is used to extend into the hexagonal hole to limit the bolt fixing block 5.

[0038] Furthermore, the hexagonal hole is coaxial with the grooved wheel bolt, and the opening faces the grooved wheel bolt.

[0039] Furthermore, the main body 3 of the device includes a base 3-1; the base 3-1 is coaxial with the grooved wheel 2, the base 3-1 is fixedly installed on the frame 1 by bolts, and the spring stop block mounting hole is located on the base 3-1.

[0040] Furthermore, one side of the side-opening cover 3-2 is installed to the device body 3 via a movable hinge, and the other side is fitted with a latch 3-3 between itself and the device body 3 to lock the side-opening cover 3-2 and prevent accidental opening.

[0041] Furthermore, when the limiting block extends into the hexagonal hole above the bolt fixing block 5 to limit the movement, the spring 3-4 is in a compressed state.

[0042] Furthermore, the pull block is used to pull the limiting block back into the spring stop mounting hole.

[0043] Furthermore, when the stop spring 4-2 is in a relaxed state, the limiting block can extend into the hexagonal hole; when the pull block is pulled, the stop spring 4-2 is compressed, and when the pull block is released, the stop spring 4-2 can help the limiting block return to its original position.

[0044] Furthermore, the bottom of the bolt fixing block 5 and the limiting block are provided with mutually matching inclined surfaces. After the bolt fixing block 5 pops out, the bottom of the bolt fixing block 5 and the inclined surface of the limiting block cooperate with each other to prevent the bolt fixing block 5 from retracting.

[0045] Furthermore, both the bolt fixing block 5 and the side opening cover 3-2 are provided with circular protrusions for installing the spring 3-4.

[0046] The grooved wheel disassembly device for a multi-wire cutting machine provided by this invention first connects the base 3-1 of the main body 3 to the frame 1 with bolts, making the hexagonal hole coaxial with the grooved wheel 2. When the grooved wheel 2 needs to be disassembled, the spring stop 4 is pulled, causing the bolt fixing block 5 to pop out due to the action of the bottom spring 3-4. At the same time, the grooved wheel 2 continues to rotate slowly. Since the groove of the bolt fixing block 5 is a hexagon that can cooperate with the grooved wheel bolt, when the grooved wheel 2 rotates to the corresponding position, after the bolt fixing block 5 pops out under the action of the bottom spring 3-4, the groove can cooperate with the grooved wheel bolt. The grooved wheel bolt is connected to the frame 1 at one end of the grooved wheel 2 by threads. Since the shape of the bolt fixing block 5 cooperates with the hexagonal hole inside the main body 3, it can restrict the circumferential rotation of the bolt fixing block 5. Therefore, the grooved wheel bolt can be extended due to the rotation of the grooved wheel 2. When the grooved wheel bolt is fully extended, the side opening cover 3-2 of the main body 3 can be opened to pull out the bolt fixing block 5 and the grooved wheel bolt together, thus completing the grooved wheel disassembly. This invention enables safe, quick, and efficient disassembly of grooved wheels, thereby improving work efficiency.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
