Description

Technical Field

[0001] This utility model relates to the field of machining production equipment, specifically an automatic ejector pin device for a three-way adjustable grinding machine. Background Technology

[0002] Grinding ejector pins are metal rods mounted on lathes or grinding machines to support workpieces and allow them to rotate. Because ejector pins need to support and fix workpieces, their usage in the machining field is enormous. In the same mold, the specifications and sizes of ejector pins are similar, and the main difference lies in the shape of the ejector pin head. Therefore, the machining of the ejector pin head is particularly important in the entire ejector pin machining process.

[0003] Currently, traditional ejector pin processing fixtures have a relatively simple structure, consisting of a transverse support block, a fixed block, and a sliding fixed block. Furthermore, during processing, the pin shank of the semi-finished ejector pin must first be placed in the groove of the fixed block, and then the sliding fixed block is moved to the ejector pin to fix it, making the operation cumbersome. Additionally, traditional ejector pin processing fixtures can only process the tip of a single ejector pin, and frequent manual replacement of the ejector pin is required for different workpieces, resulting in high labor intensity and low production efficiency. Therefore, a three-way adjustable automatic ejector pin device for grinding machines is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic ejector pin device for a three-way adjustable grinding machine, so as to solve the problems mentioned in the background art, such as the cumbersome operation of traditional ejector pin processing fixtures, the need for frequent manual replacement of ejector pins according to different workpieces, the high labor intensity, and the low production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic ejector pin device for a three-way adjustable grinding machine, comprising a grinding machine tool holder plate, an XYZ three-way adjustable seat connected to the left side of the grinding machine tool holder plate, a servo electric cylinder horizontally mounted on the XYZ three-way adjustable seat, and an ejector pin located on the grinding machine tool holder plate and mounted on the movable end of the servo electric cylinder.

The X-axis adjustment bolt is used to adjust the Y-axis adjustment mounting fixture to move left and right in the X-axis on the X-axis adjustment mounting fixture.

[0007] The front side of the Y-axis adjustment mounting fixture has at least one set of second sliding holes. A second fastener is installed in the second sliding hole. The second fastener extends into the cavity of the second sliding hole and is connected to the electric cylinder mounting fixture. A Y-axis adjusting bolt is connected laterally on the right side of the electric cylinder mounting fixture. The Y-axis adjusting bolt is used to control the servo electric cylinder to move forward and backward along the Y-axis adjustment mounting fixture.

[0008] Furthermore, the right side of the Z-axis adjustment mounting fixture is provided with at least one set of sliding holes and fasteners. The fasteners pass laterally through the sliding holes and are connected to the left side of the fixing fixture. The sliding holes are arranged along the vertical direction of the Z-axis adjustment mounting fixture. The bottom end of the Z-axis adjusting bolt is spirally inserted into the X-axis adjustment mounting fixture and connected to the bottom left side of the grinding machine tool holder.

[0009] Furthermore, both the second fastener and the first fastener can be fastening screws, and the overall width of the left end face of the first fastener protruding outside the first sliding hole exceeds the cavity width of the first sliding hole.

[0010] Furthermore, a Y-axis fixing block is integrally connected to the left side of the Y-axis adjustment mounting fixture. The left end of the Y-axis adjusting bolt spirals through the electric cylinder mounting fixture and is connected to the Y-axis fixing block. The cross-sectional shape of both the Y-axis fixing block and the X-axis fixing block is rectangular. The vertical height of the Y-axis fixing block exceeds half of the vertical height of the Y-axis adjustment mounting fixture, and the installation position of the Y-axis fixing block is perpendicular to the installation position of the Y-axis adjustment mounting fixture. The installation position of the X-axis fixing block is also perpendicular to the installation position of the X-axis adjustment mounting fixture.

[0011] Furthermore, the bottom end of the Y-axis adjustment mounting fixture is connected to a sliding column, which extends vertically into the third sliding hole, and the diameter of the bottom end of the sliding column exceeds the cavity width of the third sliding hole.

[0012] The beneficial effects of this utility model are:

[0013] This utility model features a simple structure, strong applicability, and easy and rapid positioning. It can be used in conjunction with automated equipment and, with the help of the XYZ three-way adjustable seat, enables fine adjustment of the up, down, left, right, forward and backward positions of the stroke-adjustable servo electric cylinder. It can control the extension length of the ejector pin while meeting the position adjustment requirements for changing blades of different thicknesses and workpieces of different lengths. This reduces the labor intensity of frequently changing ejector pins in traditional operations, greatly improves production efficiency, and is suitable for large-scale production.
