The dust suction component can collect the dust generated during slotting and grinding. The construction environment is protected.

The invention discloses an automatic grooving device for automatic feeding of tooth bars, comprising a frame, a grooving device, a transverse movement mechanism of the grooving device, a lifting device of the grooving device, a feeding chute for tooth bars, and an automatic feeding device. The upper end of the frame is provided with a transverse movement mechanism of the slotting device, and the upper end of the moving part of the transverse movement mechanism of the slotting device is provided with a lifting device of the slotting device. Cooperate to realize the automatic feeding and unloading of the tooth bar, improve the slotting efficiency of the tooth bar, improve the slotting quality, reduce the labor intensity, and set the slotting device lifting device and the slotting device transverse mechanism to drive the slotting device to move up and down, left and right, The slotting device is more flexible, improves the slotting efficiency of the tooth bar, and improves the slotting accuracy of the tooth bar. The lifting device of the slotting device drives the slotting device to slot the tooth bar from bottom to top or from top to bottom. Even better, the notches are neat and the depth of the grooves is consistent.

The invention discloses a grooved bar slotting process for a long quartz boat, comprising the following steps: A. making a quartz round bar into a square bar; B. cutting both ends of the square bar to check the flatness, length and verticality of the square bar C. Embed several square rods on the upper surface of the graphite plate with equal number of parallel "V"-shaped grooves, pour the connection between the square rods and the "V"-shaped grooves with liquid wax, and cool the liquid wax to solidify the liquid wax. Complete the fixing of the square bar; D. Put the graphite plate on which the square bar is fixed with wax on the table of the CNC machine tool; E. Adjust the angle of the blade axis of the CNC machine tool and install the blade; F. Call the program of the CNC machine tool to open the square bar Grooving; G. After the grooving is completed, the bar is waxed and cleaned. The invention has the advantages of good positioning and fixing effect of the quartz square bar, high slotting precision, less damage during slotting, easy removal of the bar after slotting, simultaneous slotting of multiple square bars, and high slotting efficiency.

The invention relates to equipment for processing an arc-shaped notch in a ball of a ball valve. The equipment for processing the arc-shaped notch in the ball of the ball valve comprises a bottom plate, a sleeving column, a side vertical plate, a limiting plate, an inner supporting mechanism and a locking mechanism, wherein the side vertical plate is mounted on the top of the left end of the bottom plate; the sleeving column is positioned on the upper side of the middle of the bottom plate; the left side surface of the sleeving column is connected with the side vertical plate; the limiting plate is mounted at the left end of the sleeving column; the bottom of the limiting plate is connected with the top of the bottom plate; the sleeving column has a hollow structure; the inner supporting mechanism is distributed in the sleeving column; the locking mechanism is mounted on the limiting plate; and the inner supporting mechanism comprises a spiral rod, a contact plate, a connecting column,an inner supporting plate, an adjusting column and a rotating body. By the equipment for processing the arc-shaped notch in the ball of the ball valve, the problems that when a ball of an existing ball valve is grooved by cutting, the ball of the ball valve is not locked firmly, the locking effect of the ball of the ball valve is poor, the ball of the ball valve may rotate at a certain angle, andthus, the grooving effect of the ball of the ball valve is poor can be solved.

The invention relates to a plate slotting machine, which comprises a bottom plate, a transmission belt, a guide block, a limit frame, a slotting mechanism, a limit device, a pushing mechanism and a grinding mechanism. The middle part of the bottom plate is provided with an H-shaped square groove, and the transmission belt is installed In the H-shaped square groove opened in the middle of the bottom plate, the guide blocks are symmetrically distributed on the front and rear sides of the H-shaped square groove of the bottom plate.
