Description

Technical Field

[0001] This utility model relates to the field of stainless steel cutting technology, specifically to a cutting machine base with quick tool change capability. Background Technology

[0002] When machining stainless steel tools, a tool holder is needed to install the cutting tool in order to ensure that the cutting tool can be reliably connected to the power output end of the cutting equipment.

[0003] The existing stainless steel cutting tool holder mainly consists of a mounting base, mounting holes on the mounting base, and multiple locking bolts installed on the upper side of the mounting base. When fixing the cutting tool, the cutting tool is first inserted into the mounting hole, and then the cutting tool is locked on the mounting base by tightening the locking bolts one by one.

[0004] While existing stainless steel cutting tool holders can accommodate stainless steel cutting tools, the method of tightening each bolt individually makes the process of assembling and disassembling the cutting tools on the tool holder cumbersome, thus hindering the quick replacement of cutting tools according to actual machining needs. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by this utility model is to provide a cutting machining stand with quick tool change capability, based on the current state of the technology.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: This utility model proposes a cutting machining seat with quick tool change capability, including a mounting seat, on which a mounting hole is provided, and a cutting tool body is installed in the mounting hole. A quick-release assembly is installed at the top of the mounting seat facing the mounting hole. The quick-release assembly includes a sliding hole, a pressure rod, a spring, a linkage plate, a cross rotating plate, a rotating shaft, a screw head, an anti-loosening washer, and a screw groove.

[0009] Furthermore, the sliding hole penetrates the mounting base, and the cutting tool body penetrates the mounting hole.

[0010] Furthermore, the cutting tool body consists of a tool holder and a cutting head mounted on one end of the tool holder.

[0011] Furthermore, the screw groove is formed in the middle of the top of the mounting base, and the anti-loosening washer is adhered to the mounting base at the outer periphery of the top of the screw groove.

[0012] Furthermore, the screw head is located directly above the screw groove, the rotating shaft is connected to the top of the screw groove, and the cross-shaped rotating plate is welded to the top of the rotating shaft.

[0013] Furthermore, the rotating shaft passes through the linkage plate and rotates with the linkage plate, and a convex ring is reserved on the lower outer part of the rotating shaft to cooperate with the anti-loosening washer.

[0014] Furthermore, the pressure rods are symmetrically installed on both sides of the bottom end of the linkage plate, the sliding hole is opened at the top of the mounting base directly opposite the mounting hole, the pressure rods are symmetrically installed on both sides of the bottom end of the linkage plate, the spring is installed between the bottom end of the linkage plate and the mounting base, the pressure rod passes through the spring, and the two ends of the spring are respectively welded to the linkage plate and the mounting base.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention features a quick-release assembly installed on the mounting base. After the cutting tool body is inserted into the mounting hole, the rotating shaft is moved downwards directly by a cross plate to ensure that the screw head at the bottom of the shaft contacts the screw groove. At this point, the bottom end of the pressure rod is flush with the sliding hole end. Then, by rotating the cross plate, the rotating shaft and screw head are rotated, allowing the screw head to screw into the screw groove. As the screw head screws in, the pressure rod is moved downwards via a linkage plate, thus clamping and limiting the cutting tool body. Similarly, when replacing the cutting tool body, simply separating the screw head from the screw groove allows the pressure rod to spring up quickly under spring action, facilitating rapid disassembly and replacement of the cutting tool body. Because this disassembly and assembly method only requires one rotation to limit the cutting tool body on the mounting base, it avoids the tedious operation of repeatedly tightening bolts, thereby increasing the efficiency of cutting tool body replacement and facilitating rapid replacement of cutting tools according to actual processing needs.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-2 As shown, a cutting machining stand with quick tool change capability in this embodiment includes a mounting base 1. The mounting base 1 has a mounting hole 3, and a cutting tool body 2 is installed inside the mounting hole 3. A quick-release assembly 4 is installed at the top of the mounting base 1 directly opposite the mounting hole 3. The quick-release assembly 4 includes a sliding hole 401, a pressure rod 402, a spring 403, a linkage plate 404, a cross-shaped rotating plate 405, a rotating shaft 406, a screw head 407, an anti-loosening washer 408, and a screw groove 409. When limiting the cutting tool body 2 inside the mounting hole 3, the rotating shaft 406 is first moved downwards by the cross-shaped rotating plate 405 to ensure that the screw head 407 at the bottom of the rotating shaft 406 can... When the screw rod 402 contacts the threaded groove 409, its bottom end is flush with the end of the sliding hole 401. Then, by rotating the cross plate 405, the shaft 406 and the screw head 407 are rotated, allowing the screw head 407 to be screwed into the threaded groove 409. As the screw head 407 is screwed in, the linkage plate 404 moves the screw rod 402 downward, so that the screw rod 402 can be pressed and limited after it moves downward. Similarly, when replacing the cutting tool body 2, the screw head 407 only needs to be separated from the threaded groove 409, and the screw rod 402 can be quickly lifted up under the action of the spring 403, so as to facilitate the quick disassembly and replacement of the cutting tool body 2.

[0024] like Figures 1-2 As shown, in this embodiment, the sliding hole 401 passes through the mounting base 1, and the cutting tool body 2 passes through the mounting hole 3. The mounting hole 3 is mainly used to provide mounting space for the cutting tool body 2. The cutting tool body 2 consists of a tool holder and a cutting head installed at one end of the tool holder. The cutting tool body 2 is the main component for cutting stainless steel parts.

[0025] like Figures 1-2As shown, in this embodiment, the screw groove 409 is formed at the center of the top of the mounting base 1. The anti-loosening washer 408 is bonded to the mounting base 1 and located at the outer periphery of the top of the screw groove 409. The anti-loosening washer 408 can increase the friction between the rotating shaft 406 and the mounting base 1, thereby ensuring that the rotating shaft 406 will not loosen accidentally after the screw head 407 is screwed into the screw groove 409. The screw head 407 is located directly above the screw groove 409. The rotating shaft 406 is connected to the top of the screw groove 409. The cross rotating plate 405 is welded to the top of the rotating shaft 406. With the help of the cross rotating plate 405, the rotating shaft 406 can be easily rotated. After the rotating shaft 406 rotates, it will screw the screw head 407 into the screw groove 409.

[0026] like Figures 1-2 As shown, in this embodiment, the rotating shaft 406 passes through the linkage plate 404 and rotates with the linkage plate 404. A convex ring is pre-installed on the lower outer part of the rotating shaft 406 to mate with the anti-loosening washer 408. The convex ring fits snugly with the anti-loosening washer 408, effectively preventing the rotating shaft 406 from loosening after the screw head 407 is screwed in. The pressure rods 402 are symmetrically installed on both sides of the bottom end of the linkage plate 404. The sliding hole 401 is opened at the top of the mounting base 1 directly opposite the mounting hole 3. The pressure rods 402 are symmetrically installed on both sides of the bottom end of the linkage plate 404. Spring 403 is installed between the bottom of linkage plate 404 and mounting base 1. Pressure rod 402 passes through spring 403. Both ends of spring 403 are welded to linkage plate 404 and mounting base 1 respectively. Sliding hole 401 facilitates the easy passage of pressure rod 402 so that pressure rod 402 can be used to press and limit the installed cutting tool body 2. Spring 403 can quickly spring up pressure rod 402 after the screw head 407 separates from the screw groove 409, thereby facilitating the quick disassembly and replacement of cutting tool body 2.

[0027] The specific implementation process of this embodiment is as follows: First, the cutting tool body 2 is inserted into the mounting hole 3 and fixed in place by the quick-release assembly 4. Then, simply connect the mounting base 1 to the external cutting equipment, and the stainless steel workpiece can be cut using the cutting tool body 2. During the cutting process, after the cutting tool body 2 is inserted into the mounting hole 3, the rotating shaft 406 is moved downwards directly by the cross plate 405 to ensure that the screw head 407 at the bottom of the rotating shaft 406 can contact the screw groove 409. At this time, the bottom end of the pressure rod 402 is flush with the end of the sliding hole 401. Then, by rotating the cross plate 405, the rotating shaft 406 and the screw head 407 are rotated, realizing the screw head 407 moving towards the screw groove. In the screw-in process of 409, the screw head 407, while being screwed in, causes the pressure rod 402 to move downward via the linkage plate 404. This downward movement of the pressure rod 402 achieves clamping and limiting of the cutting tool body 2. Similarly, when replacing the cutting tool body 2, simply separating the screw head 407 from the screw groove 409 allows the pressure rod 402 to spring up quickly under the action of the spring 403, facilitating quick disassembly and replacement of the cutting tool body 2. Because this disassembly and assembly method only requires one rotation to limit the cutting tool body 2 on the mounting base 1, it avoids the tedious operation of repeatedly tightening bolts, thereby making the replacement efficiency of the cutting tool body 2 higher and facilitating the quick replacement and use of the cutting tool according to actual processing needs.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
