Description

Technical Field

[0001] This utility model relates to a clamp-type plate cutting head with a track wheel clamped by the upper and lower rails and a lever structure for pressing down the handle, belonging to the field of plate cutting machine manufacturing. Background Technology

[0002] EP3415473B1, entitled "Sheet Metal Cutting System", comprises: a scribing slider; a longitudinal guide including a pair of opposing surfaces, the lower surface of which is adapted to face the sheet metal being processed, and the longitudinal guide including opposing upper surfaces equipped with a pair of parallel tracks adapted to be slidably coupled to the scribing slider; at least one suction cup coupled (e.g., rigidly engaged) to the lower surface of the longitudinal guide, preferably aligned in plan view with the lower (and upper) surfaces of the longitudinal guide itself, the suction cup being adapted to selectively adhere to the sheet metal (surface) and defining a substantially flat contact surface for the longitudinal guide on the sheet metal (surface), wherein the tracks are arranged on opposite sides relative to the median plane of the suction cup itself (parallel to the longitudinal axis of the longitudinal guide), and, for example, due to this solution, a better distribution of mechanical stress applied to the cutting system is achieved to eliminate or at least mitigate orientation variations of the longitudinal guide that may result in irregular scribing or damage to the surface of the sheet metal. Specifically, during the movement of the slab along the longitudinal guide, when longitudinal scribe lines are formed on the slab, the angular momentum on the longitudinal guide is released due to the pressure applied to the scribe line slider. The scribe member 33 includes a handle 332 of the aforementioned rod 331, the handle 332 being connected to the (first) end 331a of the rod 331, while at the opposite (second) end 331b of the rod 331, the scribe wheel 333 is rotatably connected. The rod 331 is arranged such that its longitudinal axis is perpendicular to the contact plane of the suction cup 41 (on the visible surface of the slab 50), in such a way that the (first) end 331a of the rod 331 is away from the contact plane relative to the (second) end 331b of the rod 331. The axis of rotation of the scribe wheel 333 is substantially perpendicular to the intermediate plane of the suction cup, which is perpendicular to the lower surface of the longitudinal guide 20 and parallel to the longitudinal axis of the longitudinal guide 20. Preferably, the handle 332 includes a neck 332a, in which a hole 332b suitable for receiving the first end 331a of the rod 331 is drilled. The problems are as follows: 1. Whether the roller in the scribing (marking) slider slides horizontally or vertically along the track, it rolls along the track surface in an open manner, rather than rolling along the track surface with a clamp. Therefore, when the roller jumps while rolling forward, the scribing (marking) wheel will also jump, inevitably causing incomplete cutting on the plate cutting surface, thus affecting the cutting quality, the quality of the plate's cut surface, and the yield of the plate's cut surface. 2. Because the handle and scribing wheel in the scribing slider are designed vertically, during scribing (marking) cutting, the operator needs to press down on the handle while simultaneously driving the scribing slider, which is not only laborious and time-consuming but also inefficient. Summary of the Invention

[0003] Design objective: To avoid the shortcomings of the prior art, this design proposes a cutting head with a track wheel (U-groove bearing) whose concave arc surface can be clamped by the upper and lower track rails to form a gapless fit, and a clamp-type plate cutting head where the downward pressing handle is designed to be a lever-type downward pressing lever instead of a vertical pressing handle.

[0004] Design Scheme: To achieve the above design objectives, this utility model features the following structural design: 1. The track wheel surface is clamped by the track, which is a technical feature of this utility model. The purpose of this design is as follows: In the engraving slider disclosed in background technology EP3415473B1, the roller, whether horizontally or vertically installed, always rolls on the track surface with its concave arc surface. When there are impurities on the track surface, the roller will inevitably jump on the track surface. This jumping will cause the engraving wheel (cutting wheel) it drives to jump, resulting in missed cuts on the cutting lines of the board. This missed cuts will cause the enamel on the cut surface of the board to chip off locally after cutting, thus affecting the cutting quality and the quality of the board. To solve this problem, this utility model replaces the roller with a U-groove bearing. Since the U-groove bearing has much lower fitting precision and rolling resistance than the roller, it not only has less resistance when moving along the track but also prevents deviation. Secondly, this utility model uses a track composed of double guide rails, forming a clamping fit between the double guide rails and the U-groove bearing surface. This prevents the U-groove bearing from passing through when there are impurities on the track surface, allowing passage only after the impurities are removed. This avoids the phenomenon of the cutting wheel missing sections, thus preventing localized chipping of the enamel on the cut surface of the sheet metal and ensuring the quality of the cut surface. 2. The second technical feature of this utility model is the replacement of the vertical handle in EP3415473B1 with a lever-type downward pressing design. The purpose of this design is that the handle in EP3415473B1 uses vertical downward pressure to allow the scoring wheel to complete the scoring (scribing) cutting of the enamel on the sheet metal surface, which is laborious and difficult to control the downward pressure. This utility model, however, uses a lever-type downward pressing structure, which not only makes the downward pressure easier to control but also saves a lot of effort. For example, under the same conditions of scribing (marking) cutting the plate, this utility model requires less than one-tenth the force of the background technology EP3415473B1.

[0005] Technical solution: A clamp-type ceramic plate cutting machine head, including a cutting machine head, wherein square grooves are provided on the lower part of both sides of the slide in the cutting machine head, and U-shaped groove bearings are fixed to the slide in front and behind by washers, screws and square nuts respectively.

[0006] Compared with the prior art, this utility model has two advantages: First, it designs the multi-segment short rails as a clamping rail design, realizing the clamping of the upper and lower short rails on the U-shaped groove shaft surface in the cutting device, thus solving the defects of the EP3415473B1 technology. Second, it designs the vertical pressing of the handle as a lever pressing, which not only makes the pressing force easy to control but also saves a lot of effort. Under the same cutting conditions, this utility model requires less than one-tenth of the force required by the prior art EP3415473B1. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the end face structure of a clamp-type plate cutting machine head.

[0008] Figure 2 This is an exploded view of the cutting head, showing the following components: 5-1 screw, 5-2 side wheel, 5-3 screw, 5-4 handle, 5-5 spring, 5-6 cutting wheel, 5-9 washer, 5-10 U-groove bearing, 5-11 screw, 5-12 slide, 5-13 square nut, and 5-4 tightening screw.

[0009] Figure 3 This is a schematic diagram of the exploded structure of the short track body. Detailed Implementation

[0010] Example 1: Refer to Appendix Figure 1-3 A clamp-type ceramic tile cutting machine head includes a cutting machine head 3. The lower part of both sides of the slide 5-12 in the cutting machine head 3 is provided with square grooves 5-12-1. U-groove bearings 5-10 are fixed to the slide 5-12 one in front and one behind by washers 5-9, screws 5-11 and square nuts 5-13 respectively.

[0011] The square groove 5-12-1 mates with the square nut 5-13. The slide 5-12 is designed with a threaded hole 5-12-2, which mates with a tightening screw 5-14. The tightening screw 5-14 tightens the square nut 5-13. The height of the U-shaped groove bearing 5-10 is adjusted by adjusting the tightness of the tightening screw 5-14, ensuring that the slider moves smoothly and without gaps on the guide rail. The U-shaped groove bearings 5-10 are distributed in two rows, one in front and one behind, and the U-shaped groove bearings 5-10 are seamlessly fitted with the optical axis 1-1 surface on the short rail body 1. The optical axis 1-1 on the short rail body 1 mates with the guide rail 1-2.

[0012] The handle 5-4 of the cutting head 3 is longer than 20 cm. A cutter wheel 5-6 is installed on one side of the handle 5-4. The cutter wheel is installed on the handle 5-4 by screws 5-1. A side wheel 5-2 is installed on one side of the handle 5-4. The side wheel 5-2 is connected to the handle 5-4 by screws 5-1 and nuts 5-3. The handle 5-4 is connected to the carriage 5-12 by screws 5-1. The handle 5-4 is connected to the carriage 5-12.

[0013] Features of the cutting device:

[0014] The U-groove bearings 5-10 on the slider 5-12 of the cutting device 5 are arranged in two rows, upper and lower, and fit seamlessly with the round steel (optical shaft) 1-1 on the short rail body 1. The advantage of this is that it can ensure that the cutting system slides smoothly on the short rail body 1 and improve the bending strength of the short rail body 1.

[0015] An extended handle 5-4 is used. A cutting wheel (blade) 5-6 is mounted on one side of the handle 5-4, and the blade is fixed to the handle 5-4 with screws 5-1. A side wheel 5-2 is mounted on the other side, and the side wheel 5-2 is connected to the handle 5-4 with screws 5-1 and nuts 5-3. The handle 5-4 is connected to the slide 5-12 with screws 5-1. The handle 5-4 is extended and distributed with the slide 5-12. The advantages are: even force distribution on both sides, easier cutting, and the ability to apply relatively large force to cut through the surface enamel of the board.

[0016] Multiple U-groove bearings 5-10 are installed on the slide 5-12. One type of U-groove bearing 5-10 is fixed to the slide 5-12 by a washer 5-9 and a screw 5-11, while the other type is fixed to the slider 5-12 by a washer 5-9, a screw 5-11, and a square nut 5-13. The slider 5-12 is designed with a square groove 5-12-1, which mates with the square nut 5-13. The slider 5-12 is also designed with a threaded hole 5-12-2, which mates with a tightening screw 5-14. The tightening screw 5-14 tightens the square nut 5-13. The height of the U-groove bearing 5-10 is adjusted by adjusting the tightness of the tightening screw 5-14, ensuring that the slider moves smoothly and without gaps on the guide rail.

[0017] Spring 5-5 ensures that handle 5-4 can spring up freely.
