Detailed Description

The present application is described in further detail below with reference to all of the figures.

The embodiment of the application discloses cutter slotting equipment.

Referring to fig. 1, the tool slotting device comprises a machine tool 1, wherein a grinding wheel 11 for machining a tool is mounted on the machine tool 1, a supporting table 12 is arranged on the machine tool 1, a three-jaw chuck 2 is fixed on the upper surface of the supporting table 12, and the axis of the three-jaw chuck 2 and the circle center of the grinding wheel 11 are located on the same vertical straight line. The grinding wheel 11 is used to groove the tool. The support base 12 supports the three-jaw chuck 2. The three-jaw chuck 2 holds a tool so that the tool at the axial center of the three-jaw chuck 2 can be grooved by the grinding wheel 11.

Referring to fig. 1 and 2, a first sliding table 14 is fixed on the upper surface of a machine tool 1, a second sliding table 15 is connected to the first sliding table 14 in a sliding manner, a support table 12 is fixed on the second sliding table 15, a wedge-shaped sliding strip 151 is arranged on the second sliding table 15, a sliding groove 141 matched with the sliding strip 151 is arranged on the first sliding table 14, the sliding strip 151 is connected to the sliding groove 141 in a sliding manner, a gear 143 and a rotating rod 142 are arranged in the first sliding table 14, the gear 143 is fixedly connected to the rotating rod 142, the rotating rod 142 is connected to the side wall of the first sliding table 14 in a rotating manner, a rack 152 is arranged on the surface of the second sliding table 15 close to the first sliding table 14, the rack 152 is meshed with the gear 143, a hand wheel 144 is fixed at one end of the rotating rod 142, and the hand wheel 144 is located on the outer side of the first sliding table 14. The hand wheel 144 is used for an operator to rotate the rotating rod 142 and the gear 143, and the gear 143 rotates to drive the rack 152 to move, so that the second sliding table 15 is driven to slide on the first sliding table 14. In the sliding process, the sliding strip 151 slides in the sliding groove 141, and the sliding position of the second sliding table 15 is limited, so that the second sliding table 15 moves horizontally and linearly. Therefore, the supporting table 12 drives the three-jaw chuck 2 to clamp the tool to move in the horizontal linear direction, and grooving and processing of the grinding wheel 11 on different positions of the tool are further realized.

Referring to fig. 2 and 3, the three-jaw chuck 2 includes a rail plate 21 and a plurality of jaws 22, the jaws 22 are engaged with the rail plate 21, a clamping groove 221 is formed on one side of the jaws 22 close to the axis of the three-jaw chuck 2, and a clamping block 222 is arranged on the clamping groove 221. The three jaws 22 slide on the rotating rail plate 21 to move close to or away from each other, so as to drive the clamping blocks 222 on the clamping grooves 221 to clamp or loosen the tool, and clamp the tool when the jaws move close to each other, thereby ensuring that the tool can be stably grooved.

Referring to fig. 3, a convex clamping pad one 225 is disposed on a surface of the clamping block 222 facing to the axial center of the three-jaw chuck 2, and the clamping pad one 225 is made of an elastic material. The surface of the first clamping pad 225 is provided with a first anti-skid thread 2251. The convex clamping pad I225 is gradually squeezed in the process of abutting against the cutter, so that stable clamping on the cutter is realized. The first anti-slip threads 2251 increase the friction between the tool surface and the first clamping pad 225, which improves the stability of the clamped tool.

Referring to fig. 3, the upper end of the clamping block 222 is connected to an extension block 224 through a folding member 223, when the extension block 224 and the folding member 223 are located on the same vertical line, a convex clamping pad two 226 is disposed on a surface of the extension block 224 facing to the axis of the three-jaw chuck 2, the clamping pad two 226 is made of an elastic material, and an anti-slip pattern two 2261 is disposed on a surface of the clamping pad two 226. The folding member 223 is erected such that the extension block 224 and the clamping block 222 are located on the same vertical line in order to clamp a long cutter. The convex clamping pad II 226 is gradually extruded in the process of matching with the clamping pad I225 to abut against the cutter, so that the long cutter is stably clamped. The second anti-slip pattern 2261 increases the friction between the tool surface and the second clamping pad 226, and improves the stability of clamping a longer tool.

Referring to fig. 1, a dust collector 13 is provided on a machine tool 1, and a suction end of the dust collector 13 is located near a grinding wheel 11 and a three-jaw chuck 2. The dust collector 13 absorbs scraps generated in the cutter processing process, and reduces pollution of splashed scraps to workshops.

The implementation principle of the cutter slotting equipment in the embodiment of the application is as follows: when slotting the cutter, firstly, an operator selects whether to erect the folding piece 223 according to the length of the cutter, and for the conventional cutter, the operator folds up the folding piece 223 to enable the extension block 224 to lean against the claw 22; for longer knives, the operator erects the folding member 223 such that the extension block 224 is in the same vertical line as the clamping block 222. When clamping a long tool, the operator rotates the rail plate 21 using the externally connected rotating levers, thereby bringing the three jaws 22 closer to each other until the first clamping pad 225 and the second clamping pad 226 abut and press the tool. After the tool is firmly clamped, according to the position to be machined, the operator rotates the hand wheel 144 to make the rotating rod 142 drive the gear 143 to rotate, so that the rack 152 meshed with the gear 143 moves to drive the sliding strip 151 of the second sliding table 15 to slide in the sliding groove 141, and the rotation is stopped until the clamped tool is placed at the corresponding position. Finally, the operator starts the external motor and the dust collector 13 to enable the grinding wheel 11 to operate to groove the cutter.
