Embodiment Construction
[0014] from Figure 1-Figure 4It can be seen from the figure that a tap grinding device is characterized in that: the tap grinding device is mainly composed of a fixed bottom plate 15, a thread moving device, a tap top clamping device and a tap support and guide device 8, and the rectangular fixed bottom plate 15 passes through the The T-shaped bolts 4 are fixed on the workbench of the grinding machine (that is, a step through hole is correspondingly provided on the fixed base plate 15, and the inner hexagonal T-shaped bolts 4 with nuts are worn, and each T-shaped bolt 4 is correspondingly slidably installed on the grinder workbench. T-shaped groove); the tap moving device is mainly composed of a sliding base plate 17, a rear fixed baffle plate 16, a front adjustable baffle plate 19, a gear 20, a rack 2, a gear shaft 3, a gear shaft seat 18 and a handwheel 1. The front side part is provided with the elongated rear fixed baffle plate 16 of unilateral dovetail groove and is fixe...

The invention discloses a screw tap grinding device, and belongs to an auxiliary device of a machine tool. The screw tap grinding device is characterized by mainly consisting of a fixed bottom plate, a screw tap moving device, a screw tap jacking and clamping device and a screw tap supporting and guiding device, wherein the fixed bottom plate is fixed on a workbench of a grinding machine through T-shaped bolts; the screw tap moving device mainly consists of a sliding bottom plate, a rear fixed baffle plate, a front adjustable baffle plate, a gear, a rack, a gear shaft, a gear shaft seat and ahand wheel; the screw tap jacking and clamping device mainly consists of a fixed center seat, a fixed center, a locking bolt, a movable center seat, a movable center, a compression spring, a pushing screw hole plate and a pushing bolt; and the screw tap supporting and guiding device mainly consists of a seat plate, a sleeve, a jacking spring, a supporting rod and a locking screw. In use, the screw tap grinding device is fixedly arranged on the workbench of the grinding machine, a flat template on the supporting rod is in full contact with two sides of a screw tap slot, a screw tap to be ground reciprocates relative to a butterfly grinding wheel, and the screw tap is recycled, so that the production cost is reduced.
Description
technical field [0001] The invention belongs to a machine tool auxiliary device, in particular to a screw tap grinding device. Background technique [0002] At present, taps are widely used in the hole processing of workpieces. In the process of hole processing, taps are prone to chipping, broken teeth, blade tip cracking, and edge wear. For enterprises with a large demand for taps, the taps should be reasonably controlled. Input cost is of great benefit to the control of production cost, so the length of tap life is particularly important. At present, there are two types of taps used in the domestic market: domestic taps and imported taps. Domestic taps are limited by the quality of production. Although the price is relatively cheap, the service life of domestic taps is relatively short; while the service life of imported taps is relatively long, but the price is higher. , have defects to varying degrees. Contents of the invention [0003] The purpose of the present inv...
