Abstract
The utility model discloses a size-adjustable multi-spindle drill bit. The drill bit comprises an installing seat body (1), wherein the upper end of the installing seat body (1) is connected with a machine tool through a spindle drillstock (2), the lower end of the installing seat body (1) is connected with a drill bit through a chuck (6), a branch spindle drillstock (3) is also arranged in the installing seat body (1), the chuck (6) is arranged at the lower part of the branch spindle drillstock (3), a branch transmission gear A (4) is arranged at the upper part of the branch spindle drillstock (3), a main transmission gear B (5) is arranged at the lower part of the spindle drillstock (2), and the spindle drillstock (2) and the branch spindle drillstock (3) are in meshed transmission connection with each other through the main transmission gear B (5) and the branch transmission gear A (4). The drill bit is characterized in that the lower part of the branch spindle drillstock (3) is in transmission connection with the chuck (6) through a universal gearing (7). The technical scheme is used for effectively solving the problems that sizes are fixed and cannot be adjusted during the drilling process of a conventional multi-drill-bit machine tool, so that production costs of enterprises can be increased, and the production efficiencies of the enterprises are also influenced; and the drill bit is simple and reasonable in structure, is scientific in design, has good applicability and is convenient to popularize and apply.
Description
Technical field:
The utility model relates to machining drill bit, is specifically related to a kind of size adjustable multi-shaft drill bit.
Background technology:
Along with the mechanical processing industry development, people more and more pay attention to the precision of machining, and drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.Drill bit commonly used mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill, though reamer and counterbit can not be holed at solid material, also they is included into traditionally drill bit one class.At present in the industry when using drilling machine to carry out drilling, when if same workpiece need to be processed a plurality of hole, normally drilling is carried out in the hole one by one, if but workpiece is to the pitch-row between each hole, when the hole depth requirement is relatively more accurate, adopt above-mentioned processing method then to be difficult to reach anticipate accuracy, if exist then processing another hole because process a hole, just there has been error in the workbench rotation process, if a plurality of need hole to be processed is arranged, then error accumulation, precision is difficult to guarantee, and operating efficiency is also very low, at present, the appearance of many drill bits lathe is arranged also in the industry, but often have very large drawback, interval between many drill bits is certain, if the size between the Kong Yukong on the parts to be processed is changed, then need again to change, this not only can cause the soaring of entreprise cost, and affected to a certain extent the production efficiency of enterprise, in sum, existing many drill bit design are poor for applicability, not too are beneficial on a large scale and promote the use of.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of size adjustable multi-shaft drill bit, this technical scheme effectively solves existing many drill bits lathe size in the drilling process and fixes, can't regulate, not only can increase the production cost of enterprise, and can affect the problem of the production efficiency of enterprise, the utility model is simple and reasonable for structure, design science, applicability is good, and is easy to utilize.
The utility model is achieved through the following technical solutions:
A kind of size adjustable multi-shaft drill bit, comprise mount pad body (1), mount pad body (1) upper end is connected with lathe by main shaft drillstock (2), the lower end is connected with drill bit by clamping head (6), also be provided with split axle drillstock (3) in the mount pad body (1), split axle drillstock (3) bottom is provided with clamping head (6), split axle drillstock (3) top is provided with a minute travelling gear A(4), main shaft drillstock (2) bottom is provided with main drive gear B(5), main shaft drillstock (2) passes through main drive gear B(5 with split axle drillstock (3)), divide travelling gear A(4) be connected by meshing transmission, it is characterized in that: described split axle drillstock (3) bottom is in transmission connection by universal driving device (7) and clamping head (6).
The further Technological improvement plan of the utility model is:
Described universal driving device (7) comprises power transmission shaft (71), and power transmission shaft (71) two ends are respectively by universal joint (72), universal joint (73) and split axle drillstock (3), movable adjustable connection of clamping head (6).
The further Technological improvement plan of the utility model is:
Be provided with more than one split axle drillstock (3) in the described mount pad body (1), each split axle drillstock (3) is provided with a minute travelling gear A(4), minute travelling gear A(4) all with main drive gear B(5) be connected by meshing transmission, each split axle drillstock (3) bottom is all by universal driving device (7) and clamping head (6) transmission.
The utility model compared with prior art has following obvious advantage:
The utility model is on the basis of existing many drill bits lathe, split axle drillstock bottom is in transmission connection by universal driving device and clamping head, realized that the distance between each drill bit is adjustable, not only improved operating efficiency, reduced the production cost of enterprise, and the utility model is simple and reasonable for structure, and design science is convenient to promote the use of.
