Bottom plate of portable cutting machine

Technical Field

The utility model relates to a technical field of manual cutting tool, a portable cutting machine bottom plate specifically says so.

Background

The cutting machine is classified into a metal material cutting machine and a non-metal material cutting machine from the viewpoint of cutting a material, and classified into a numerical control cutting machine and a manual cutting machine from the viewpoint of a control method. Wherein, the portable cutting machine has flexible and convenient use and wide application range. But due to the lack of support, the hand held cutting machine has poor orientation performance during operation, and the cutting depth and the direction of the cutting mark are difficult to control. For example, in the portable pneumatic cutter disclosed in chinese patent 2013200499805, a cutter handle is fixed to the shield at the head end of the machine body by screwing. The lifting handle designed through the hollow structure achieves the purposes of being convenient to carry, enhancing the structural firmness and reducing the production cost. However, the cutting depth and the direction of the cutting mark of the cutting machine are completely controlled by manpower when the cutting machine is used, and the necessary specifications are lacked. Therefore, Chinese patent 2014207008584 discloses a portable cutting machine, which comprises a grinding wheel and a protective cover, wherein a baffle is detachably connected to the protective cover, the baffle is perpendicular to the grinding wheel, a through hole is formed in the baffle, and the grinding wheel penetrates through the baffle from the through hole. When the cutting device is used, an auxiliary plate is placed on a plate to be cut, the edge of the auxiliary plate is aligned with the edge of the baffle, and a relatively straight cutting line can be cut well. Although the cutting depth and the trend of the cutting line can be specified, the portable cutting machine can only have one specification size, the cutting depth cannot be adjusted, each cutting machine with different specifications is required to be provided with a baffle with corresponding specification, and the same baffle cannot be suitable for cutting machines with different specifications.

Detailed Description

As shown in fig. 1, the bottom plate of the portable cutting machine of the present invention comprises a plate body 1 having at least one straight side 2, and the plate body 1 of the present embodiment is of a rectangular structure, but may also be of a semicircular or polygonal structure. The novel blade plate is characterized in that a blade groove 3, a longitudinal sliding groove 4 and a transverse sliding groove 5 are arranged on the plate body 1, the blade groove 3, the longitudinal sliding groove 4 and the transverse sliding groove 5 are strip-shaped through holes penetrating through the plate body 1, the blade groove 3 and the longitudinal sliding groove 4 are parallel to the side edge 2, the blade groove 3 is located between the longitudinal sliding groove 4 and the side edge 2, and the transverse sliding groove 5 is perpendicular to the blade groove 3. In use, the blade groove 3 can allow a blade or a grinding wheel of the cutting machine to penetrate through the blade groove 3 from the upper side of the plate body 1 to cut an object below the plate body 1, and the longitudinal sliding groove 4 and the transverse sliding groove 5 are used for connecting the cutting machine.

As shown in fig. 1 and 3, a longitudinal locking bolt 6 is installed in the longitudinal sliding groove 4, a depth limiting sliding plate 7 perpendicular to the plate body 1 is installed on the longitudinal locking bolt 6, a depth limiting sliding groove 8 is arranged on the depth limiting sliding plate 7, and the depth limiting sliding groove 8 is a strip-shaped hole perpendicular to the plate body 1; the lower end of the depth limiting sliding plate 7 is provided with a right-angle folded edge 71, and the right-angle folded edge 71 is provided with a bolt hole for mounting a longitudinal locking bolt 6. As shown in fig. 3, the width of the longitudinal sliding groove 4 matches the diameter of the longitudinal locking bolt 6, so that the longitudinal locking bolt 6 can just pass through the longitudinal sliding groove 4 and can slide along the longitudinal sliding groove 4, and a bottom groove 41 with a slightly larger width is arranged at the bottom of the longitudinal sliding groove 4, so that the head 61 of the longitudinal locking bolt 6 can sink into the bottom groove 41, and the head 61 is prevented from protruding to prevent the plate body 1 from sliding on a plane. The right-angled hem 71 of the depth stop slider 7 is closely attached to the upper surface of the panel body 1 and is locked by the nut 62 mounted on the longitudinal locking bolt 6. The nut 62 is loosened, and the depth-limiting slide plate 7 and the longitudinal locking bolt 6 can slide along the longitudinal slide groove 4.

The transverse sliding chute 5 has a similar bottom groove structure, and a left shaft seat 9 and a right shaft seat 10 which are symmetrically arranged are arranged in the transverse sliding chute 5. The left shaft seat 9 and the right shaft seat 10 are both angle irons, bolt holes for installing transverse locking bolts 11 are formed in the bottoms of the angle irons, and shaft holes 12 are formed in the upper ends of the angle irons. When the transverse locking bolt 11 is loosened, the left shaft seat 9 and the right shaft seat 10 can slide along the transverse sliding groove 5 together with the transverse locking bolt 11.

As shown in fig. 2, when in use, firstly the longitudinal locking bolt 6 and the transverse locking bolt 11 are loosened, the position of the depth limiting sliding plate 7 in the longitudinal sliding groove 4 and the positions of the left shaft seat 9 and the right shaft seat 10 in the transverse sliding groove 5 are adjusted according to the model size of the cutting machine 22; then, a left hanging lug and a right hanging lug 24 on a protective cover of the cutting machine 22 are respectively arranged in the shaft holes of the left shaft seat 9 and the right shaft seat 10 through hinge shafts, a bolt 25 at the rear end of the cutting machine 22 is inserted into a depth limiting sliding groove 8 on a depth limiting sliding plate 7, then a longitudinal locking bolt 6 and a transverse locking bolt 11 are screwed, the position of the bolt 25 in the depth limiting sliding groove 8 is adjusted, a cutting knife 26 of the cutting machine 22 extends out of the bottom of the plate body 1, and then the bolt 25 is fixed through a nut, so that the cutting machine 22 can be fixed. The cutting machine 22 can be used for cutting operation after being fixed, when in use, a ruler-shaped bar-shaped object is placed on the upper surface of the object to be cut along one side of a set cutting line, if necessary, the bar-shaped object can be temporarily fixed by a device such as bench clamp, the plate body 1 is flatly placed on the object to be cut, the side edge 2 of the plate body is leaned on the ruler-shaped bar-shaped object, meanwhile, the cutting knife 26 of the cutting machine 22 is confirmed to be pressed on the set cutting line, the cutting machine 22 is started, and the cutting machine 22 is pushed to move forwards along the routing of the ruler-shaped bar-shaped object, so that the object to be cut can. When the cutting depth is required to be adjusted in use, the cutting depth can be correspondingly adjusted by only loosening the nut on the bolt 25 and adjusting the height of the bolt 25.

In addition, as an embodiment of the present invention, the side edge 2 has a folded edge 21 that is bent upward. The arrangement of the folding edge 21 improves the height of the contact surface of the side edge 2 and the ruler-shaped strip-shaped object on the premise of not increasing the thickness of the plate body 1. The cutter 22 is more stable when pushed.
