Chamfer clamp for milling machine machining

Abstract

The invention discloses a chamfer clamp for milling machine machining. The clamp comprises a workbench, a groove is formed in the top of the workbench, a mounting groove is formed in the inner wall ofone side of the groove, a stepping motor is fixedly installed in the mounting groove, an output shaft of the stepping motor is fixedly provided with a screw rod, a sliding plate is installed on the screw rod in a threaded mode, the sliding plate is installed in a sliding groove in a sliding mode, the sliding groove is formed in one side of the sliding plate, and a first plate is installed in thesliding groove in a sliding mode; and a sliding rod is welded to one side of the first plate, a first clamping plate is welded to one side of the sliding rod, the first clamping plate is located abovethe workbench, a second clamping plate welded to the top of the workbench is arranged on one side of the groove, and the first clamping plate is located between the second clamping plate and the sliding plate. According to the clamp, the practicability is high, the structure is simple, the operation is convenient, a steel plate can be conveniently clamped, the clamping force can be conveniently controlled, the damage caused by too large clamping force to the clamp or the steel plate is prevented, and use by people is facilitated.

Description

technical field [0001] The invention relates to the technical field of machining fixtures, in particular to a chamfering fixture for milling machine processing. Background technique [0002] In order to ensure the firmness and quality of the welding during the welding process of the steel plate, it is generally required to chamfer the welding edge of the steel plate before welding. Among them, the chamfering angle of 30 degrees is the most used chamfering angle, and the chamfering angle of 30 degrees is currently processed. It is processed on an ordinary milling machine, using a flat vise as a fixture, and an ordinary end mill. Only one steel plate can be processed at a time, which is time-consuming and labor-intensive, and requires repeated tool setting. The patent document whose notification number is CN205703358U discloses a clamp for chamfering by a milling machine. The positioning elements are parallel and placed obliquely on the bottom plate of the fixture; the guide ...

[0002] In order to ensure the firmness and quality of the welding during the welding process of the steel plate, it is generally required to chamfer the welding edge of the steel plate before welding. Among them, the chamfering angle of 30 degrees is the most used chamfering angle, and the chamfering angle of 30 degrees is currently processed. It is processed on an ordinary milling machine, using a flat vise as a fixture, and an ordinary end mill. Only one steel plate can be processed at a time, which is time-consuming and labor-intensive, and requires repeated tool setting. The patent document whose notification number is CN205703358U discloses a clamp for chamfering by a milling machine. The positioning elements are parallel and placed obliquely on the bottom plate of the fixture; the guide rod and the positioning screw are respectively parallel to the bottom plate of the fixture; the guide rod is connected with the rear positioning element; the positioning screw passes through the positioning nut and is connected with the rear positioning element Connected, this design is firm in clamping, and will not cause any looseness during processing, and is designed with a clamping guide device, which is easy to operate; and the clamp can be placed on any milling machine to complete processing, with a compact structure and no need to bring your own power, cheap

[0003] However, there are deficiencies in the above-mentioned design. The above-mentioned design is not convenient for clamping the steel plate, and it is not convenient for controlling the instantaneous clamping force when the rear positioning element is in contact with the steel plate. It is easy to cause damage to the clamp and the steel plate, which is not conducive to people. Therefore, we propose a chamfering fixture for milling machine processing to solve the above problems
