The screw tap chuck adjusting and clamping device is characterized in that a screw tap chuck is arranged on a screw tap chuck adjusting and clamping seat, the screw tap chuck adjusting and clamping seat is fixed on a post workbench by penetrating a nail through a screw hole, a clamping seat clamping groove is arranged at the upper end of the screw tap chuck adjusting and clamping seat, a chuck boss is aligned with the clamping seat clamping groove and clamped into the clamping seat clamping groove, and the screw tap chuck adjusting and clamping device is not limited in that: the clamping mode of the screw tap can cause the problem that the two sides of the screw tap are not parallel and level, so that the finally processed screw tap is low in precision, similarly, errors can exist on the two sides of the drill body on the two sides when the stepped drill is processed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current ladder bores adds man-hour, has supplementary clamping mechanism seldom, makes the ladder bore machining precision higher, in order to improve its weak point, the utility model provides a tight auxiliary mechanism of clamp of processing ladder brill.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
the utility model provides a tight complementary unit of clamp of processing ladder brill, including the connecting plate of vertical setting, the horizontal interval is equipped with two supporting rollers on the connecting plate of one side is bored to the orientation waiting to process the ladder, the backing roller is including the taper supporting part and set up the connecting rod on taper supporting part bottom surface, connecting rod and the coaxial setting of taper supporting part, each connecting rod and the connecting plate rigid coupling of level setting, leaves the V type groove that holds waiting to process the ladder and bore between two supporting rollers of syntropy setting, waits to process the ladder and bores the side and contradict on a taper supporting part outer peripheral face, and another downside is contradicted on another taper supporting part outer peripheral face.
The utility model discloses the during operation, when the installation is treated processing ladder and is bored, processing equipment one end will treat that the stalk portion that processing ladder bored is fixed, utilizes the outer peripheral face of two supporting roller taper supporting parts to contradict simultaneously and is treating processing ladder to bore, will treat that the brill body that processing ladder bored places at V type inslot, and two supporting roller taper supporting parts will treat that the brill body both sides that processing ladder bored press from both sides tightly to flush mutually.
Compared with the prior art, the beneficial effects of the utility model are that: due to the arrangement of the two groups of supporting rollers, when the step drill to be machined is machined, the side face of the drill body of the step drill to be machined is abutted, and shaking cannot be generated in the rotating process, so that the machining precision of the step drill is improved, and the device is suitable for industrial production and has strong practicability.
Each connecting rod is fixed with the connecting plate through a bearing. The setting of bearing makes the friction reduce between connecting rod and the connecting plate, connects more level and smooth.
An elastic rubber layer is attached to the outer peripheral surface of the conical supporting part. The arrangement of the elastic rubber layer ensures that the conical supporting part of the supporting roller cannot damage the cutting edge when abutting against the step drill to be processed.
The connecting plate is provided with a plurality of screws, and the free ends of the screws are abutted to the corresponding vertical sliding rails. The height of the two groups of supporting rollers can be adjusted up and down by arranging the sliding rails and the sliding blocks, and stepped drills with different diameters can be machined.
Two vertical slide rails are arranged at intervals. The two groups of supporting rollers are more stable when moving up and down due to the arrangement of the two sliding rails.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 connecting plate, 2 backing rolls, 201 taper supporting parts, 202 connecting rods, 3V type grooves, 4 elastic rubber layers, 5 support frames, 501 slide rails, 6 sliding blocks and 7 screws.
Detailed Description
The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1, a clamping auxiliary mechanism for processing a step drill, including a vertically arranged connecting plate 1, two supporting rollers 2 are horizontally arranged on the connecting plate 1 facing one side of the step drill to be processed at an interval, the supporting rollers 2 include a tapered supporting portion 201 and a connecting rod 202 arranged on the bottom surface of the tapered supporting portion 201, the connecting rod 202 and the tapered supporting portion 201 are coaxially arranged, each connecting rod 202 horizontally arranged is fixedly connected with the connecting plate 1, a V-shaped groove 3 for accommodating the step drill to be processed is left between the two supporting rollers 2 arranged in the same direction, a lower side surface of the step drill to be processed is abutted against the outer peripheral surface of one tapered supporting portion 201, and another lower side surface is abutted against the outer peripheral surface of the other tapered supporting.
