Description

Technical Field

[0001] This utility model relates to the field of cutting heads, specifically to a parallel moving cutting head. Background Technology

[0002] In existing parallel movement tool head technology, the parallel movement and limiting of the moving and fixed tools rely on the combination of multiple components, such as the tool pad protrusion and the fixed tool slotted together, or the guide plate and the tool pad connected. This design requires the alignment of the holes, slots or protrusions of multiple components one by one during assembly, which not only increases the complexity of the assembly process and reduces the assembly efficiency, but also easily leads to uneven sliding clearance between the moving and fixed tools due to the cumulative error of the multi-component cooperation, affecting the stability of parallel movement. At the same time, the redundant limiting components increase the load on the overall structure of the tool head, requiring greater driving force, and are prone to reduced overall stability due to component cooperation errors.

[0003] Therefore, how to simplify the limiting structure of the parallel moving cutter head to reduce the complexity of the assembly process, improve assembly efficiency, and reduce the load on the cutter head structure and the demand for driving force has become an urgent problem to be solved in the industry.

Example 1

[0020] like Figure 1As shown, a parallel-moving cutting head, with a drive mechanism connected to its end, includes: a fixed cutting head assembly 100, a moving cutting head assembly 200, a clamping assembly 300, and a cutting head holder 400. The fixed cutting head assembly 100 includes a fixed cutting blade 110, the moving cutting head assembly 200 includes a moving cutting blade 210, and the clamping assembly 300 presses the moving cutting blade 210 together, thereby enabling the drive mechanism to drive the moving cutting blade 210 to move back and forth on the fixed cutting blade 110.

[0021] like Figure 2 As shown, to enable the fixed blade assembly 100 and the moving blade assembly 200 to slide together, the clamping assembly 300 includes a sliding member 310. The sliding member 310 has a first groove 311 on the side near the moving blade assembly 200. The moving blade assembly 200 has a first sliding end 220 that is movably connected to the first groove 311. The first sliding end 220 moves back and forth on the first groove 311. The other side of the sliding member 310 is fixed to the fixed blade assembly 100. The first groove 311 restricts the moving blade assembly 200 from moving parallel on the fixed blade assembly 100. At the same time, the clamping assembly 300 has an elastic member 320. One side of the clamping assembly 300 presses the moving blade assembly 200 together with the elastic member 320. The other side of the clamping assembly 300 is connected to a drive mechanism. like Figure 3 , 4 As shown, to achieve the pressing assembly 300 and the moving blade assembly 200 pressing and sliding on the fixed blade assembly 100, the pressing assembly 300 is provided with a driving member 330. One side of the driving member 330 is connected to the driving mechanism, and the other side of the driving member 330 is provided with a limiting groove 331. The pressing end 321 of the elastic member 320 is engaged with the limiting groove 331, and the fixed end of the elastic member 320 is located inside the limiting protrusion 313. A sliding protrusion 332 is also provided below the driving member 330. The moving blade assembly 200 is provided with a square through hole 230 corresponding to the lower part of the sliding protrusion 332. The width of the square through hole 230 is corresponding to the sliding protrusion 332. The sliding protrusion 332 also includes an extension extending from... The sliding part on one side of the square through hole 230 has a second sliding groove 312 connected to the sliding part. At this time, the moving blade is driven by the driving member 330 and the first sliding groove 311 of the sliding member 310 restricts the first parallel sliding connection of the moving blade. Furthermore, the bottom of the driving member 330 is provided with a fixing part 333, and the top of the moving blade assembly 200 is provided with a fixing hole 240 connected to the fixing part 333. The second parallel sliding connection of the moving blade on the sliding member 310 is achieved by the elastic force of the pressing end 321 on the sliding member 310, the sliding part passing through the direction through hole and the second sliding groove 312, and the assembly of the fixing part 333 and the fixing hole 240.

[0022] To achieve the protection of the moving blade assembly 200 and the fixed blade assembly 100, the fixed blade assembly 100 is provided with a detachable blade holder 400 on its upper side. The bottom of the blade holder 400 is provided with a positioning groove 410. The clamping assembly 300 is provided with a limiting protrusion 313 that matches the positioning groove 410. To further realize the setting of the positioning groove 410 in the width direction, the sliding member 310 includes two fixed ends extending on one side. The inner side of the fixed ends is used to fix the elastic member 320. The fixed ends are provided with the limiting protrusion 313. The blade holder 400 is provided with a positioning groove 410 on the side that matches the fixed ends. The positioning groove 410 includes a trapezoidal groove and a positioning part extending on one side of the trapezoidal groove. The distance from the outer side of the positioning part to the inner wall of the trapezoidal groove is set to the width of the positioning groove 410. The width matches the width of the limiting protrusion 313. At this time, the positioning groove 410 adapts to the limiting protrusion 313 in the width direction and provides the limiting protrusion 313 with forward and backward movement space in the length direction; at this time, the tool holder 400 moves left and right on the fixed tool assembly 100, but does not move forward and backward, thus achieving the initial wrapping of the fixed tool and the moving tool. like Figure 5 As shown, to further achieve fixation, the fixed blade assembly 100 includes a first mounting hole 120 on the side near the limiting protrusion 313, and the corresponding side of the blade holder 400 is provided with a second mounting hole 420. An external fixing member 430 is provided to connect with the first mounting hole 120 and the second mounting hole 420. Specifically, the external fixing member 430 can be an elastic protrusion structure or a screw. It can be engaged with the first mounting hole 120 and the second mounting hole 420 via the elastic protrusion structure, or tightened with a screw into the first mounting hole 120 and the second mounting hole 420. In this way, the fixed blade and the moving blade can be enclosed and fixed, giving the blade head of this product a better appearance.

[0023] like Figure 6 As shown, to achieve sliding friction heat dissipation of the moving blade assembly 200, the moving blade assembly 200 includes a moving blade 210, a bent portion 250, a main body 260, and a first sliding end 220. The bottom surface of the moving blade 210 is parallel to the main body of the fixed blade assembly 100. The bent portion 250 makes the main body 260 suspended relative to the fixed blade assembly 100. The side of the main body 260 near the first slide groove 311 has a downward-facing first sliding end 220. The suspension height of the main body 260 is greater than the height of the sliding member 310. To further expand the heat dissipation space, the fixed blade assembly 100 has a third slide groove 130 opposite to the suspended main body 260. The side of the sliding member 310 near the moving blade assembly 200 has a second sliding end 314, which is disposed on the third slide groove 130. The width of the third slide groove 130 is smaller than that of the main body 260.

[0024] The bending portion 250 is used to form an angle α between the end of the moving blade 210 and the main body portion 260. The size of α can be 110-150°; a preferred setting is 120°.

[0025] This utility model also realizes a quick assembly method for the cutter head, specifically as follows: Assemble the first sliding groove 311 and the first sliding end 220, and make the pressing end 321 of the elastic member 320 engage with the limiting groove 331 of the driving member 330. The drive unit 330 is connected to the tool holder 400 and its upper drive mechanism, and assembled through the limiting protrusion 313 and the positioning groove 410 to initially fix the tool holder 400, the moving tool assembly 200, the sliding member 310, and the drive unit 330. By assembling the third groove 130 with the second sliding end 314 of the slider 310, the encapsulation and installation positions of the tool holder 400 and the fixed tool are initially determined; The above structure is finally fixed by tightening the screws into the first mounting hole 120 and the second mounting hole 420.

[0026] This invention achieves rapid pre-positioning of the fixed tool assembly 100 and the clamping assembly 300 by providing a positioning groove 410 at the bottom of the tool holder 400 of the fixed tool assembly 100 and a corresponding limiting protrusion 313 on the clamping assembly 300, through the precise engagement of the groove and the protrusion. This concave-convex mating structure directly guides component alignment during assembly, eliminating the need to align multiple holes or slots one by one, effectively simplifying the assembly process, reducing manual calibration steps, and significantly shortening assembly time. Simultaneously, the mechanical engagement of the positioning groove 410 and the limiting protrusion 313 ensures the relative positional accuracy of the components before fixing, avoiding repeated adjustments caused by alignment deviations in traditional multi-component assembly, fundamentally improving assembly efficiency, and is particularly suitable for high-efficiency assembly requirements in mass production scenarios.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
