Abstract
Description
Technical Field
[0001] This utility model relates to the field of hub product manufacturing technology, and in particular to a device for processing internal splines in hub products. Background Technology
[0002] In the field of mechanical manufacturing, hub products are widely used, and their performance directly affects equipment operation. Internal splines, as a key connection structure in hub products, play a crucial role in transmitting torque and precise centering. In industries such as automotive, aerospace, and machine tools, they are vital to the stability, reliability, and motion accuracy of power transmission. Currently, in traditional machining, planing cuts the internal spline teeth using a planer on a planer, offering low equipment cost, high flexibility, and the ability to process various tooth modules. However, it suffers from low production efficiency and its accuracy is greatly affected by human factors, making it difficult to meet the demands of high-precision and mass production. Broaching, on the other hand, uses a broach on a broaching machine to form the spline in a single pass, offering high efficiency, good precision, and excellent surface quality, making it suitable for mass standardized production. However, during machining, the broach must be removed before installation when changing workpieces, which is cumbersome and impacts production efficiency. Utility Model Content
[0003] The purpose of this utility model is to provide a device for processing internal splines in hub products in order to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] A device for machining internal splines on hub products includes a worktable and a feeding mechanism. The feeding mechanism includes a fixed frame fixed to the lower surface of the worktable, a screw threaded rod mounted on the fixed frame, a threaded seat mounted on the screw threaded rod, and a stepper motor connected to one end of the screw threaded rod. A slide is fixed to the feeding mechanism, and a clamping mechanism is provided on the slide. The clamping mechanism includes a clamping frame fixed to the slide, a fixed plate fixed relative to the clamping frame, left and right screw threads and a guide rod mounted opposite to each other on the fixed plate, clamping blocks mounted opposite to each other on the left and right screw threads, a power component connected to one end of the left and right screw threads, a collection box provided on the slide, a press frame fixed to the worktable, a cylinder mounted on the press frame, a mounting seat fixed to the output end of the cylinder, and a grooving cutter fixed to the lower surface of the mounting seat.
[0006] Further configuration: The screw is rotatably connected to the fixed frame, and the threaded seat and the screw are connected by a thread.
[0007] Further configuration: A T-shaped groove is provided on the upper surface of the worktable, and a T-shaped slider is provided on the lower surface of the slide table. The T-shaped slider of the slide table is slidably connected in the T-shaped groove of the worktable.
[0008] Further configuration: The left and right helical screws are rotatably connected to the fixed plate, the guide rod is fixed on the fixed plate, the clamping block is threadedly connected to the left and right helical screws, and the clamping block is slidably connected to the guide rod.
[0009] Further features: The collection box is slidably connected to the clamping frame, and multiple sets of feeding grooves are opened through the upper surface of the clamping frame and communicate with the collection box. Rubber pads are provided in the clamping grooves of the clamping blocks.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] By setting up a feeding mechanism and a clamping mechanism, the power component of the clamping mechanism drives the left and right spiral screws to rotate, which in turn moves the clamping block along the guide rod direction to clamp the workpiece. Then, the stepper motor of the feeding mechanism drives the spiral screw to rotate, which moves the threaded seat laterally, thereby moving the clamping mechanism on the slide table. This can realize automatic feeding, enabling multiple workpieces to be processed in one clamping operation, saving a lot of operation time and improving production efficiency.
