Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral element smoothing clamping technology, and in particular to a spiral element smoothing clamping device. Background Technology
[0002] Using a polishing machine to polish spiral components requires vertically fixing the spiral component onto the machine, where the spiral surface is polished by abrasive particles. During clamping, the spiral component is first placed horizontally on a rubber pad, and after the fixture shaft passes through the center of the spiral component and is tightened with screws, the assembly of the spiral component and fixture is then placed vertically again. This process makes installation difficult and inefficient. To ensure clamping efficiency, a spiral component polishing clamping device that allows for quick replacement of spiral components is needed. Utility Model Content

[0004] The technical solution of this utility model is as follows: a spiral element smoothing clamping device, including a tooling base 1, a tooling shaft assembly 2, a pressure cover 3, a stop sleeve 4, and a screw 5;
[0005] The lower flange 1-2 has a recessed hole in the center and a U-shaped groove on the side, with one vertical side of the U-shaped groove extending to the top of the lower flange 1-2;
[0006] The spiral element is placed vertically on the tooling base 1, and the gear plate 1-4 is in spline contact with the inner hole of the spiral element; one end of the tooling shaft assembly 2 passes through the spiral element and is installed in the recess of the lower flange 1-2 on the tooling base 1; a positioning pin is installed on the bottom side of the tooling shaft assembly 2. After the positioning pin passes through one vertical side of the U-shaped groove, the tooling shaft assembly 2 is rotated, and the positioning pin moves upward and moves to the other vertical side to tighten.
[0007] Lift the tooling shaft assembly 2, and the pressure cover 3 fitted on the outside of the tooling shaft assembly 2 will press the spiral element. The screw 5 passes through the side of the pressure cover 3 and is fixed to the tooling shaft assembly 2. The spiral element and the tooling base 1 are lifted as a whole by the tooling shaft assembly 2. The pin at the other end of the tooling shaft assembly 2 is engaged with the slot on the main shaft of the polishing machine and clamped. The entire spiral element polishing clamping device is quickly connected by the pin and the slot of the main shaft of the polishing machine. At the same time, the stop sleeve 4 installed on the main shaft of the polishing machine is slid off the connecting shaft of the polishing machine and engaged with the pin at the other end of the tooling shaft assembly 2 for fixation.
[0008] The tooling base includes two parallel angle steels 1-1, a lower flange 1-2, a base plate 1-3, a gear plate 1-4, long screws 1-5, and short screws 1-6; both the base plate 1-3 and the gear plate 1-4 have through holes in their centers; after the lower flange 1-2 passes through the through holes of the base plate 1-3 and the gear plate 1-4 in sequence, the lower flange 1-2, the base plate 1-3, and the gear plate 1-4 are fastened together using long screws 1-5;
[0009] The two parallel angle steels 1-1 are located below the lower flange 1-2, and the base plate 1-3 is fastened to the two parallel angle steels 1-1 using short screws 1-6.
[0010] The slot of the main shaft of the polishing machine is in the shape of a straight line, and the pin at the other end of the tooling shaft assembly 2 rotates from one end to the other end within the straight slot.
[0011] The bottom of the stop sleeve 4 has a groove, the position of which corresponds to the position of the pin at the other end of the slot.
[0012] The tooling shaft assembly 2 is fixed above the pressure cover 3 with a lifting plate, and the tooling shaft assembly 2 is lifted by the lifting plate.
[0013] The beneficial effects of this invention are as follows: This invention achieves more stable clamping of the spiral element through the combination of a slot and a pin. This invention reduces the spiral element replacement time from 30 minutes to 10 minutes, significantly improving the clamping efficiency of the spiral element. This invention uses a stop sleeve and a pin at the upper end of the tooling shaft assembly to achieve quick replacement with the main shaft of the polishing machine while effectively preventing workpiece detachment. This invention uses two parallel angle steels to horizontally place the tooling shaft base, achieving vertical clamping of the polishing workpiece. This invention uses different specifications of gear plates, base plates, and pressure caps to achieve polishing clamping of spiral elements of different specifications, achieving a universal effect. This invention improves the clamping efficiency between the polishing assembly and the polishing machine by more than 98%. Attached Figure Description

[0017] The specific embodiments of the present invention are described in detail below with reference to the technical solutions and accompanying drawings.
[0018] like Figure 1As shown, a spiral element smoothing clamping device includes a tooling base 1, a tooling shaft assembly 2, a pressure cover 3, a stop sleeve 4, and a screw 5.
[0019] After assembling the tooling base 1, place it stably on the ground. The helical element is placed vertically on the tooling base 1. The gear plate 1-4 on the tooling base 1 engages with the spline of the inner hole of the helical element to achieve circumferential positioning of the helical element. The tooling shaft assembly 2 is passed through the helical element, and the positioning pin at the lower end of the tooling shaft assembly 2 is rotated into the groove of the lower flange 1-2 on the tooling base 1. The lower flange 1-2 has a groove structure adapted to the positioning pin. The groove structure is a U-shaped groove, with one vertical side of the U-shaped groove extending to the top of the lower flange 1-2. After the positioning pin passes through one vertical side of the U-shaped groove, rotate the tooling shaft assembly 2, and the positioning pin moves upward and tightens in the other vertical side.
[0020] Lift the tooling shaft assembly 2, lower the pressure cap 3 to press the spiral element, and secure the pressure cap 3 with screws 5. Lift the spiral element and tooling base 1 as a whole using the tooling shaft assembly 2. The pin at the upper end of the tooling shaft assembly 2 engages with the slot on the polishing machine spindle, allowing the entire tooling to be quickly connected via the pin and the slot on the polishing machine spindle. The polishing machine spindle has a slot structure adapted to the pin. Simultaneously, slide down the stop sleeve 4 to prevent the tooling from detaching from the polishing machine. The slot on the polishing machine spindle is in a straight line shape, and the pin at the other end of the tooling shaft assembly 2 rotates from one end to the other within the straight slot. The bottom of the stop sleeve 4 has a groove, the position of which corresponds to the position of the pin rotated to the other end of the straight slot.
