Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a mechanical processing fixture adapted for special-shaped parts. Background Art

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. A machining fixture is also called a machining positioning device. It is a device used to fix the object to be processed during machining so that it occupies the correct position for construction or inspection. Since the clamping range of most existing fixtures is limited, the applicable workpiece specifications are too single. If the workpiece becomes loose during machining, it will fall or collide with other objects, causing a certain degree of damage. In order to improve the machining efficiency of special-shaped parts, a machining fixture is needed, but the existing machining fixtures still have the following shortcomings:

[0003] For example, the utility model with application number 202120065039.7 discloses a clamp for mechanical processing. The utility model adjusts the distance between the movable plate and the fixed plate on the clamping mechanism according to the size of the part, and fixes it with a third fastening screw. It can clamp welded parts of any size, so that the clamping mechanism can clamp both horizontally and vertically. The angle of the clamping mechanism is adjustable, which improves production efficiency and saves manpower. However, similar to the comparative documents of the above-mentioned application, when the existing processing fixtures are used, since most processing fixtures are not convenient for adjusting the state of the clamping parts according to the shape of the object to be processed, the special-shaped workpieces are easy to loosen during the clamping process, resulting in reduced practicality of the processing fixture and reduced use efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a machining fixture suitable for special-shaped parts is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a mechanical processing fixture adapted for special-shaped parts, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanical processing fixture adapted to special-shaped parts, comprising a workbench and a clamping block, a supporting column foot is installed at the bottom of the workbench, and limited through grooves are opened on both sides of the upper end of the workbench, and protective frames are installed on the left and right sides of the workbench, and a servo motor is arranged inside the protective frame, and a rotating shaft is connected to the front end of the servo motor, and a screw rod is connected to the front end of the rotating shaft, and a movable block is connected to the outside of the screw rod, and a clamping groove is opened inside the upper end of the movable block, and a clamping block is arranged on the outside of the clamping block.

[0007] Furthermore, the number of the supporting column feet is two, and the two supporting column feet are symmetrically arranged on both sides of the bottom of the workbench with respect to the front center axis of the workbench.

[0008] Furthermore, the movable block is embeddedly connected to the workbench, and the movable block is slidably connected to the workbench via a screw rod.

[0009] Furthermore, the inner dimensions of the clamping groove match the outer dimensions of the clamping block, and the clamping block is slidably connected to the movable block via the clamping block.

[0010] The utility model provides a mechanical processing fixture adapted to special-shaped parts, which has the following beneficial effects:

[0011] 1. The utility model can, through the setting of the screw rod, when using the mechanical processing fixture adapted to the special-shaped parts, use the screw rod arranged inside the workbench to avoid the situation that most processing fixtures are not convenient to adjust the lateral distance between the clamping parts appropriately to the size of the processing parts, which makes the processing process of the items time-consuming and labor-intensive, and causes the use efficiency of the processing fixture to decrease. The servo motor is protected by the protective frames arranged on the left and right sides of the workbench to prevent the servo motor from being damaged. At the same time, the output shaft of the servo motor is connected to the rotating shaft through a coupling. The operation of the servo motor drives the rotating shaft to rotate, so that the screw rod connected to the front end of the rotating shaft rotates inside the workbench, and cooperates with the limiting through groove opened at the upper end of the workbench so that when the screw rod rotates, the movable block connected to the outside of the screw rod drives to slide left and right inside the workbench, thereby adjusting the use distance between the movable blocks and improving the use efficiency of the equipment.

[0012] 2. The utility model, through the setting of the clamping block, can avoid the problem that most processing fixtures are inconvenient to adjust the state of the clamping piece according to the shape of the object to be processed through the clamping block connected inside the movable block when using the machining fixture for adapting special-shaped parts, causing the special-shaped workpiece to be easily loosened during the clamping process, resulting in a problem of reduced flexibility in the use of the processing fixture. The clamping groove opened inside the movable block is engaged with the clamping block set at the rear end of the clamping block, and then the clamping block can be easily disassembled and installed through the clamping groove, thereby avoiding that most clamping blocks are installed on the inner side of the movable block by fastening bolts, which is time-consuming and laborious when replacing and disassembling the clamping block, prolonging the processing time and reducing the flexibility of the processing fixture during use, making it convenient for the equipment to quickly replace the clamping block according to special-shaped workpieces of different shapes, avoiding the loosening of the workpiece and further improving the overall use efficiency of the processing fixture.
