Description

Technical Field

[0001] The utility model relates to the technical field of precision parts processing, in particular to a cutting mechanism for processing precision parts. Background Art

[0002] Precision parts refer to parts with high dimensional accuracy, high surface finish, complex geometric shapes or special functions. The processing of precision parts is a high-precision manufacturing process that involves the use of various mechanical equipment to change the size or performance of parts to meet high precision and other high-performance requirements. Ultra-precision parts use higher-precision processing technology and measurement methods during the manufacturing process to ensure that the dimensional accuracy, surface quality and performance indicators of the parts reach extremely high levels.

[0003] In the process of precision parts processing, a cutting mechanism is needed. After searching, the Chinese patent CN219818238U in the prior art discloses an end angle cutting mechanism for parts processing and production, including an operating table, an inner groove with a through structure is opened at the upper end of the operating table, a control box is installed at the right end of the operating table, an adjustment mechanism is installed in the inner groove, a moving device is installed on the adjustment mechanism, and there is a gap between the moving device and the operating table, and a limit device and a top frame are provided on the moving device. The top frame is an inverted L structure and is welded at the rear end center of the operating table. In this utility model, by providing a limit device on the moving device, the end angle of the part is in a suspended structure, so that the part can be completely cut off by the cutting knife, and the cutting knife is prevented from cutting the limit seat when descending. By controlling the crank, the limit seat can be moved back and forth, so that relatively wide parts can be cut, and there is no need to repeatedly change the position of the parts for cutting, thereby improving work efficiency.

[0004] However, during use, the utility model requires manual rotation and adjustment of the rod to clamp and fix the parts, and the handle needs to be manually rotated to adjust the position of the parts. This operation is relatively cumbersome and may affect the cutting accuracy and cannot meet production needs. Therefore, a cutting mechanism for processing precision parts is proposed to solve the above problems. Utility Model Content

This operation is relatively cumbersome and may affect the cutting accuracy and cannot meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting mechanism for processing precision parts, comprising a workbench and a fixed seat fixedly installed on the top of the workbench, a support column is arranged on the side of the top of the workbench away from the fixed seat, a clamping mechanism for clamping the parts is arranged on the top of the fixed seat, and a lifting and cutting mechanism extending to one side of the support column is arranged inside the support column;

[0007] The clamping mechanism comprises a top plate arranged on the top of the fixing seat, a telescopic cylinder extending to the bottom of the top plate is fixedly installed on the top of the top plate, a mounting block is fixedly connected to the output end of the telescopic cylinder, a lifting plate is arranged between the fixing seat and the top plate, a first hinge and a second hinge are respectively fixedly connected to the opposite side of the lifting plate and the top plate, a hinge rod is hinged to the opposite side of the first hinge and the second hinge, and a connecting rod hinged to the two hinge rods is rotatably connected to one side of the mounting block;

[0009] Furthermore, the number of the first hinges and the number of the second hinges are both two, and the two first hinges and the two second hinges are symmetrically located on opposite sides of the top plate and the lifting plate respectively.

[0010] Furthermore, a clamping plate is fixedly connected to one side of the fixed seat and the lifting plate, a limiting rod is fixedly connected to one side of the fixed seat and the top plate, and the lifting plate is slidably connected to the limiting rod.

[0011] Furthermore, a fixing block is fixedly connected between the lifting block and the support rod, and a movable groove adapted to the fixing block is provided inside the support column.

[0014] Furthermore, the interior of the workbench is slidably connected to a collection box extending to the front thereof, and the upper surface of the workbench is provided with a discharge port connected to the collection box.

[0015] Compared with the prior art, the utility model provides a cutting mechanism for machining precision parts, which has the following beneficial effects:

[0016] 1. The cutting mechanism for processing precision parts drives the mounting block to move up and down by setting a telescopic cylinder, so that the mounting block can simultaneously drive the two connecting rods to rotate upward. At this time, the two connecting rods can simultaneously drive the four articulated rods to rotate. At this time, the articulated rods will drive the lifting plate to move up and down, thereby facilitating the clamping and fixing of the parts. The staff only needs to control the telescopic cylinder, which improves the clamping efficiency.

[0017] 2. The cutting mechanism for processing precision parts drives the lifting block to move downward by setting an electric push rod, and then drives the support rod and the cutting device to move downward by the lifting block, so as to facilitate the cutting device to cut the parts. It solves the problem that the parts need to be clamped and fixed manually by manually rotating and adjusting the rod, and the position of the parts needs to be adjusted manually by manually rotating the crank. This operation is relatively cumbersome and may affect the cutting accuracy and cannot meet the production needs. BRIEF DESCRIPTION OF THE DRAWINGS
