Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to an adjustable angle drilling and tapping machine clamp. Background Technology

[0002] A drilling and tapping machine is a machine that can drill and tap holes on the surface of a workpiece. Its main structural components include machine tools, cutting tools, conveying devices, and control systems. When using a drilling and tapping machine, a fixture is needed to hold and position the workpiece.

[0003] Currently, Chinese utility model patent CN221640192U discloses a fixture for a benchtop drilling and tapping machine. This fixture uses push plates on both sides to push and clamp the workpiece inwards. While this prevents workpiece displacement after clamping, other problems exist during use, such as poor positioning, requiring manual adjustment of the hole position to align with the tapping assembly after workpiece placement, and the workpiece's tendency to tilt upwards during tapping, reducing tapping quality. Furthermore, it lacks multi-angle adjustment capabilities. For ring-shaped workpieces with numerous holes, changing the fixture after drilling requires loosening the fixture, manually rotating the workpiece, readjusting, and tightening, which is time-consuming and labor-intensive. To address these problems, we propose an adjustable-angle drilling and tapping machine fixture. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable angle drilling and tapping machine clamp, which solves the problems of poor positioning effect and lack of multi-angle adjustment function of existing clamps.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable angle drilling and tapping machine clamp, comprising a housing, wherein a drive shaft and a worm gear are rotatably connected inside the housing via bearings, a worm wheel is fixedly sleeved on the surface of the drive shaft, the top end of the drive shaft extends through to the outside of the housing and is mounted on a rotating disk, a place seat and a fixing frame are respectively bolted to the top of the rotating disk, a groove is formed on the surface of the place seat, a threaded rod is rotatably connected inside the fixing frame, a threaded plate is threadedly connected to the surface of the threaded rod, connecting plates are installed on both sides of the threaded plate, and a limit plate is rotatably connected inside the connecting plate via a rotating shaft.

[0006] The above technical solution achieves good positioning effect, can quickly guide and place workpieces, facilitates chip removal and collection, ensures workpiece processing quality, and has multi-angle adjustment function. It is simple and convenient to operate, improves the work efficiency of personnel, and has high flexibility and practicality.

[0007] The present invention is further configured such that: a first throttle is installed at the other end of the worm gear, and a second throttle is installed at the other end of the threaded rod.

[0008] By adopting the above technical solution, the setting of the first and second throttles facilitates the rotation of the worm and threaded rod by personnel.

[0009] The present invention is further configured such that a maintenance plate is bolted to one side of the housing.

[0010] By adopting the above technical solution and setting up the inspection plate, it is convenient for personnel to install and maintain the components inside the shell.

[0011] The present invention is further configured such that: a mounting plate is installed on the front side of the housing, and two mounting holes are formed inside the mounting plate.

[0012] By adopting the above technical solution, the installation plate and mounting holes make it easy for personnel to fix the housing to the machine base with screws, reducing the trouble of temporary drilling.

[0013] The present invention is further configured such that a pointing block for use in conjunction with a rotating disk is bolted to the top of the housing.

[0014] By adopting the above technical solution and setting the pointing block, it is possible to use itself as an anchor point, which makes it easy for personnel to accurately observe the angle of the rotating disk after it has rotated.

[0015] The present invention is further configured such that: two guide rods are provided through the top of the threaded plate, and the bottom end of the guide rods is welded to the fixed frame.

[0016] By adopting the above technical solution, the guide rod can limit the threaded plate and prevent it from flipping over during the up-and-down movement.

[0017] The present invention is further configured such that both the connecting plate and the limiting plate are made of stainless steel.

[0018] Using the above technical solution, the connecting plate and the limiting plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model first fixes the housing to the designated position with screws. After the housing is fixed, the annular workpiece is placed on the groove. After the workpiece is placed, the bottom will fit against the placement seat. Then, the limiting plate is pulled outward and straightened so that it is above the workpiece. Finally, the second throttle is held by hand to drive the threaded rod to rotate. When the threaded rod rotates, it will drive the threaded plate and the connecting plate to move downward. When the connecting plate moves downward, it will drive the limiting plate to press the workpiece. This can achieve good positioning effect, quickly guide and place the workpiece, facilitate the discharge and collection of debris, and ensure the processing quality of the workpiece.

[0021] 2. This utility model allows the worm gear to rotate by holding the first throttle handle. When the worm gear rotates, it drives the worm wheel to rotate as well. When the worm wheel rotates, it drives the transmission shaft and the rotating disk to rotate. When the rotating disk rotates, not only will the scale corresponding to the indicator block change, but it will also drive the storage seat and the workpiece to rotate together. It has a multi-angle adjustment function, is simple and convenient to operate, improves the work efficiency of personnel, and has high flexibility and practicality. Attached Figure Description
