Description

Technical Field

[0001] This utility model belongs to the technical field of vertical honing machines and their accessories, and in particular relates to a positioning device for a ceramic cylinder liner vertical honing machine. Background Technology

[0002] The vertical honing machine for ceramic cylinder liners is a type of vertical honing machine. It is a CNC machine specifically designed for high-precision machining of the inner bore of ceramic cylinder liners. During the machining process of ceramic cylinder liners, the vertical honing machine first needs to fix the ceramic cylinder liners to the positioning device to prevent the ceramic cylinder liners from shifting position during the machining process.

[0003] Chinese patent application CN219403829U discloses a positioning seat for a vertical honing machine specifically for ceramic cylinder liners. The seat includes a chuck with positioning pins on its jaws to fix the ceramic cylinder liner being processed. Each positioning pin has an elastic block that contacts the ceramic cylinder liner. The elastic block has an installation groove with a pressing element inside. The chuck has an indicator light, and both the pressing element and the installation groove have conductive plates to power the indicator light, causing it to illuminate. Adjusting the chuck in the device moves the positioning pins outward, causing the elastic block on the positioning pin to contact and press against the ceramic cylinder liner until it presses against the pressing element. This causes the two sets of conductive plates to contact, activating the indicator light and illuminating it to alert the operator. This allows the operator to precisely control the force applied to fix the ceramic cylinder liner, improving the fixing efficiency.

[0004] The aforementioned positioning seat for a vertical honing machine specifically for ceramic cylinder liners features a chuck with three jaws. A positioning pin is located at the upper end of each jaw, and an elastic block is fixedly mounted on the outer wall of the upper end of the positioning pin. The positioning pin penetrates into the ceramic cylinder liner, and the elastic block on its outer wall abuts against the inner wall of the ceramic cylinder liner, thus positioning the liner. However, different models of ceramic cylinder liners have different lengths. To ensure positioning stability, the length of the positioning pin must be greater than half the length of the ceramic cylinder liner. However, the length of this positioning pin is not adjustable, thus limiting its applicability. Therefore, we provide a positioning device for a vertical honing machine for ceramic cylinder liners to solve the aforementioned problems. Utility Model Content

The threaded column 202 is connected to the positioning claw 201 through the connecting screw sleeve 201b, which will push the positioning claw 201 to rotate. However, due to the presence of the sliders 201a on both sides of the positioning claw 201, the rotation of the positioning claw 201 is restricted, so that the positioning claw 201 can only move in a straight line along the slide groove 101, thereby achieving the effect of adjusting the position of the positioning claw 201. Example 2

[0029] Please see Figure 5 Based on embodiment 1, an extension component 3 is also provided. Through the cooperation of the threaded disc 302a and the threaded groove 301b, the length of the combination of the hollow column 301 and the sliding column 302 can be adjusted so that it can be used for ceramic cylinder liners of different lengths.

[0030] Specifically, the upper side wall of the positioning claw 201 is provided with a mounting hole 201c, and the extension component 3 is vertically arranged above the positioning claw 201.
