Description
Technical field
The utility model relates to a kind of Work treatment installation, particularly a kind of screw workpiece boring grab.
Background technology
In the boring of screw workpiece end, screw workpiece is threaded with boring grab by general employing, then holes.But because screw flight has certain damage, screw workpiece is threaded in boring grab has certain gap, not only easily cause drill bit axle center different from screw workpiece, and drill bit easily vibrates and sideslip, then fracture, cause boring inaccurate.In addition, after holing to screw rod, metal fragment is trapped in the screwed hole of fixture, causes screw workpiece not easily to screw out.
Utility model content
The technical problems to be solved in the utility model is to provide the screw workpiece boring grab that a kind of boring is more accurately detained with minimizing metal fillings.
In order to solve the problems of the technologies described above, screw workpiece boring grab of the present utility model, comprises chuck body and wing bolt; Described chuck body one end is provided with screw workpiece and stretches into hole; The described chuck body other end is provided with drill bit and stretches into hole; Described screw workpiece stretches into hole and drill bit and stretches into hole and to be communicated with and coaxial; The aperture that described screw workpiece stretches into hole is greater than the aperture stretching into hole in described drill bit; Described screw workpiece stretches in hole and is provided with internal thread; Described chuck body sidepiece is provided with at least two are stretched into hole screw workpiece lock hole perpendicular to described screw workpiece; Described screw workpiece lock hole is provided with internal thread; Described wing bolt is threadedly connected in described screw workpiece lock hole respectively; The first chip-removal hole is provided with bottom described chuck body; The connectivity part that hole is stretched into described screw workpiece in described first chip-removal hole top and drill bit stretches into hole is communicated with; Described first chip-removal hole top is infundibulate; The second chip-removal hole is provided with bottom described chuck body; Described second chip-removal hole top is stretched into hole with described drill bit and is communicated with; Described second chip-removal hole top is the bar-shaped trough stretching into hole length direction along described drill bit.
The upper and lower both sides of described chuck body are respectively arranged with two symmetrical screw workpiece lock holes, and described wing bolt has four and is threadedly connected to respectively in described screw workpiece lock hole.
Adopt structure of the present utility model, be greater than drill bit stretch into hole dimension because screw workpiece stretches into hole dimension, in both connectivity parts, position can be stretched into screw workpiece and position.Owing to stretching into hole sidepiece in screw workpiece, screw workpiece lock hole and butterfly lock(ing) bolt are set, can lock nut workpiece, reduce screw workpiece vibration, thus improve boring accuracy.Due to corresponding drill hole and drill bit place, first chip-removal hole and the second chip-removal hole are set respectively, the metal fillings because boring produces can be discharged in time, reduce the impact of metal fillings on boring, improve boring accuracy, and minimizing metal fillings is trapped in screw workpiece and screw workpiece stretches between hole, facilitates screw workpiece to select.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, screw workpiece boring grab of the present utility model, comprises chuck body 7 and wing bolt 1.
Chuck body one end is provided with screw workpiece and stretches into hole 3.The chuck body other end is provided with drill bit and stretches into hole 5.Screw workpiece stretches into hole and drill bit and stretches into hole and to be communicated with and coaxial.The aperture that screw workpiece stretches into hole is greater than the aperture stretching into hole in drill bit.Screw workpiece stretches in hole and is provided with internal thread.Screw rod stretches into hole from screw workpiece and stretches into, and is threadedly connected to screw workpiece and stretches in hole, until screw workpiece is encountered in screw rod end stretch into the step place that hole and drill bit stretch into hole connectivity part, just stops stretching into.Drill bit stretches into hole by drill bit and stretches into, and then holes to screw workpiece end.The cross-sectional diameter of drill bit is less than the aperture that drill bit stretches into hole.
Chuck body sidepiece is provided with at least two are stretched into hole screw workpiece lock hole 2 perpendicular to screw workpiece.Screw workpiece lock hole is provided with internal thread.If screw lock hole is in chuck body the same side, then thumb screw is by two location point clamping screw workpiece of the same side, thus further standing screw workpiece, reduce screw workpiece vibration.If screw lock hole is in the both sides of chuck body, then thumb screw is by both sides clamping screw workpiece, thus further standing screw workpiece, reduce screw workpiece vibration, reduce drill bit sideslip and beat, thus the accuracy of raising boring.
Wing bolt is threadedly connected in screw workpiece lock hole respectively.Wing bolt end is provided with butterfly-like knob, conveniently manually directly rotate wing bolt, stretching into the degree of depth and stretching into dynamics of wing bolt can be adjusted as required in time, use more convenient, thus raising screw workpiece stretches into the position in hole in screw workpiece, the axiality of both raisings, improves boring accuracy.
The first chip-removal hole 4 is provided with bottom chuck body.The connectivity part that hole is stretched into screw workpiece in first chip-removal hole top and drill bit stretches into hole is communicated with.The junction that hole and drill bit stretch into hole is stretched into because the metal fillings got out from screw workpiece end drops on screw workpiece, by arranging chip-removal hole at this place, metal fillings can be discharged in time, reduce the resistance to drill bit rotational, thus improve the accuracy of boring, and minimizing is trapped in screw workpiece and screw workpiece stretches between hole, thus the impact that minimizing metal fillings is selected screw workpiece.First chip-removal hole top is infundibulate.By arranging funnel shaped first chip-removal hole top, upper end bell mouth is larger, can receive more metal fillings, reduces metal fillings further and is detained.
The second chip-removal hole 6 is provided with bottom chuck body.Second chip-removal hole top is stretched into hole with drill bit and is communicated with.Second chip-removal hole top is the bar-shaped trough stretching into hole length direction along drill bit.Second chip-removal hole being set by stretching at drill bit bottom hole, can accelerating to discharge the metal fillings on drill bit, reduce metal fillings to the impact of drill bit, thus improve the boring accuracy of drill bit.By the second chip-removal hole top being arranged the bar-shaped trough structure stretching into hole length direction along drill bit, can collect and discharge drill bit and stretching into more metal fillings in hole, reduce metal fillings further to the impact of drill bit, improve the boring accuracy of drill bit.
As shown in Figure 1, the upper and lower both sides of chuck body are respectively arranged with two symmetrical screw workpiece lock holes, and wing bolt has four and is threadedly connected to respectively in screw workpiece lock hole.By arranging two symmetrical screw workpiece lock holes respectively in the upper and lower both sides of chuck body, not only increase the fastness of locking, and can from both sides clamping screw workpiece, raising screw workpiece and screw workpiece stretch into the axiality in hole, thus improve boring accuracy.
