Description
Technical Field
The utility model relates to a clamp, in particular to a clamp for drilling a pin shaft.
Background
The drilling operation is a common operation method in the manufacturing process of mechanical parts, the drilled hole is usually used for circulating various media or for assembling other parts, and the workpiece needing drilling is usually installed on a workbench by using a clamp.
In the work piece that needs drilling, the work piece can receive the great impact force of drill bit in the drilling process, therefore the work piece is put and is compressed tightly on operation panel or anchor clamps bottom plate usually to the powerful impact force of drill bit makes the work piece bounce from normal drilling station, probably causes danger or reduction in production efficiency. Therefore, the pin hole of the workpiece is matched with the clamp and is tightly pressed on the bottom plate, the structural design has great limitation on the height of the workpiece and the distance from the pin hole of the workpiece to the bottom surface of the workpiece, and when the size is not matched with the distance from the pin shaft of the clamp to the bottom plate of the clamp, a new clamp needs to be replaced for drilling. For workpieces with the same pin hole size or the same pin hole center position, the same set of jigs may not be shared, but manufacturing different jigs is inefficient and wastes resources.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects and provides a clamp for drilling a pin shaft.
In order to overcome the defects in the background art, the technical scheme adopted by the utility model for solving the technical problems is as follows: the clamp for drilling the pin shaft comprises a base, wherein a stand column is arranged on the base, a positioning transverse plate is arranged at the upper end of the stand column, positioning holes for drilling the pin shaft are formed in the positioning transverse plate, 2 tensioning rods are arranged on the stand column, one tensioning rod is hinged to one end of a pressing plate, the other end of the pressing plate is connected with the other tensioning rod through a bolt, and a fixing block is arranged on the stand column and below the positioning transverse plate.
According to another embodiment of the present invention, further comprising the fixed block is movably connected to the pillar.
According to another embodiment of the utility model, the contact surface of the fixing block and the pin shaft is V-shaped.
According to another embodiment of the present invention, the positioning hole further comprises at least 1 positioning hole.
According to another embodiment of the present invention, the base is further provided with a fixing bolt hole.
The utility model has the beneficial effects that: this kind of a anchor clamps for round pin axle drilling is through setting up a plurality of locating holes to set the fixed block to movable structure, can be used for the round pin axle of fixed various sizes, the locating hole also sets up can various sizes, and accommodation is wider, and the structure is more general.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural diagram of a top view of the present invention;
FIG. 3 is the schematic view of FIG. 2 with the positioning cross plate removed;
wherein: 1. the device comprises upright columns, 2, a positioning transverse plate, 3, a fixing block, 4, a tensioning rod, 5, a pressing plate, 6, a base, 7 and positioning holes.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the device comprises a base 6, a stand column 1 is arranged on the base 6, a positioning transverse plate 2 is arranged at the upper end of the stand column 1, a positioning hole 7 for drilling a pin shaft is arranged on the positioning transverse plate 2, 2 tightening rods 4 are arranged on the stand column 1, one tightening rod is hinged to one end of a pressing plate 5, the other end of the pressing plate 5 is connected with another tightening rod through a bolt, and a fixing block 3 is arranged on the stand column 1 and below the positioning transverse plate 2.
The fixed block 3 is movably connected on the upright post 1. Due to the fact that the pin shafts to be machined are different in size, adjustment is possibly needed during machining, the pin shafts correspond to the positioning holes 7 in the positioning transverse plate 2, and drilling is conveniently conducted on the pin shafts.
As shown in fig. 3, the contact surface of the fixing block 3 with the pin shaft is V-shaped. In order to better fix the pin shaft, the pin shaft is cylindrical, and the pin shaft can be better clamped by arranging the V-shaped contact surface.
At least 1 positioning hole 7 is provided. The quantity that sets up of locating hole 7 can adapt to the round pin axle of multiple model and carry out the end face drilling, and the practicality is stronger.
Examples
Firstly, a clamp is fixed on a machine tool, the periphery of a base 6 is fixed on the machine tool through bolts, then a pin shaft to be processed is placed on the base 6, the V-shaped surface of each fixing block 3 is attached, the position of each fixing block 3 is adjusted, so that the pin shaft corresponds to a positioning hole 7 in a positioning transverse plate 2 and is clamped tightly through a hinged pressing plate 5, and a punching device on the machine tool can position the pin shaft through the positioning hole 7.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
