Description

Technical Field

[0001] This application relates to the field of CNC machining technology, and in particular to a CNC machining platform with positioning function. Background Technology

[0002] In traditional CNC machining, fixed-angle fixtures are often used to position the workpiece. Once these fixtures are designed and manufactured, the angle at which they can fix the workpiece is basically fixed, making it difficult to adjust flexibly. For example, for complex parts that need to be machined with multiple different angle surfaces, using fixed fixtures often requires designing and manufacturing different fixtures for each angle. This not only consumes a lot of time and cost, but also reduces production efficiency and increases the risk of machining errors due to frequent fixture changes.

[0003] In some machining scenarios, although the workpiece's positioning angle can be adjusted manually, this method relies heavily on the operator's experience and skills, resulting in extremely low efficiency. Operators need to spend a significant amount of time measuring and fine-tuning the angle, and it's difficult to guarantee consistent accuracy with each adjustment. When high machining precision is required, manual adjustment is insufficient, easily leading to large dimensional deviations in the machined products and an increased scrap rate.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] A CNC machining platform with positioning function includes a machining table, on both sides of which are fixed positioning frames.

[0008] Preferably, a sliding groove is provided at the center of the inner wall of the positioning frame, and a cylinder is fixed on one side of the bottom of the positioning frame.

[0009] Preferably, the output end of the cylinder is connected with a push block, one end of the push block extends into the sliding groove and is fixed with the bottom of the sliding plate.

[0010] Preferably, a fixing member is welded on one side of the top of the positioning frame, and the gear is rotationally connected with the inner wall of the fixing member.

[0011] Preferably, an electric push rod one is symmetrically installed in the inside of the positioning clamping seat, and the top end of the electric push rod one extends to the outside of the positioning clamping seat and is connected with the inner wall of the top plate.

[0012] Preferably, a connecting block is connected between the clamping plate and the positioning clamping seat and the top plate, and the inner wall of one end of the two connecting blocks close to each other is connected with a clamping block through a screw.

[0013] To sum up, the present application has the following beneficial technical effects:

[0014] The present application can adjust the machining end face of the workpiece at any time by driving the positioning clamping seat to rotate through the engagement of the rack and the gear.
