Description
Technical Field
[0001] The utility model belongs to the technical field of tool arm ejector rod processing, and particularly relates to a clamping device for a tool arm ejector rod. Background Technique
[0002] Machining centers are widely used in the field of machining. The most prominent feature of a machining center is that it has a tool magazine system that can replace and store tools. The tool magazine system is a device that provides the storage and tool change requirements during the automated machining process. Its automatic tool change mechanism and tool magazine that can store multiple tools have changed the traditional human-based production method. Through computer program control, various different machining requirements, such as milling, drilling, boring, tapping, etc., can be completed, greatly shortening the machining time and reducing production costs. This is the biggest feature of the tool magazine system. The tool arm ejector rod is an important structure of the tool, and its function is to buffer the impact generated during tool change.
[0003] When the existing tool arm ejector rod is produced, a limiting groove needs to be opened on it to limit the telescopic range of the tool arm ejector rod and prevent the thick rod part from shrinking too much and hitting the thin rod part. Over time, the service life of the tool arm ejector rod will be reduced. Therefore, the tool arm ejector rod needs to be clamped and fixed for grooving operation. Summary of the Utility Model
[0004] The utility model provides a clamping device for a tool arm ejector rod, aiming to solve the problem that clamping and fixing are required to ensure stability during the grooving process of the tool arm ejector rod mentioned in the above background technique.

A base plate is fixedly connected between the mounting frames. A plurality of groups of clamping devices are arranged side by side on the top of the base plate. Each group of clamping devices includes a clamping component one and a clamping component two. The clamping component one and the clamping component two are arranged oppositely front and back. A cylinder is installed at the rear position of each clamping component two on the top of the base plate. A positioning block is fixedly connected to the telescopic end of each cylinder. The clamping component one and the clamping component two clamp and fix the tool arm ejector rod. In this solution, the telescopic end of the cylinder controls the movement of the positioning block to ensure that all tool arm ejector rods have the same position on the clamping device.
[0006] Preferably, each clamping component one includes a clamping base one, the clamping base one is fixedly connected to the top of the base plate, and a clamping cover seat one is covered on the top of the clamping base one. Screw holes one are oppositely opened on the top of the clamping cover seat one.
[0007] Preferably, bottom grooves I are formed at the tops of the clamping bases I, and top grooves I are formed at the bottoms of the clamping cover seats I. The top grooves I correspond to the bottom grooves I. In this solution, the top grooves I and the bottom grooves I are combined to clamp and fix the thin rods of the tool arm.
[0008] Preferably, each clamping assembly II includes a clamping base II, which is fixedly connected to the top of the base plate and is arranged directly behind the clamping base I. A clamping cover seat II is provided on the top of the clamping base II, and screw holes II are oppositely formed at the top of the clamping cover seat II.
[0009] Preferably, bottom grooves II are formed at the tops of the clamping bases II, and top grooves II are formed at the bottoms of the clamping cover seats II. The top grooves II correspond to the bottom grooves II. In this solution, the top grooves II and the bottom grooves II are combined to clamp and fix the thick rods of the tool arm.

In this solution, the clamping cover seat I and the clamping base I are combined to clamp and fix the thin rod of the tool arm, and the clamping cover seat II and the clamping base II are combined to clamp and fix the thick rod of the tool arm.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] Place the thin rod part of the tool arm on the bottom groove I, and clamp and fix the thin rod of the tool arm by combining the clamping base I and the clamping cover seat I. Place the thick rod part of the tool arm on the bottom groove II, and clamp and fix the thick rod of the tool arm by combining the clamping base II and the clamping cover seat II to ensure the stability of the tool arm top rod when a limiting groove is formed on the thick rod of the tool arm.
[0013] After placing the tool arm top rod on the bottom groove, the telescopic end of the cylinder controls the positioning block to move towards the position of the thick rod of the tool arm to push the tool arm top rod to move until the ends of all the thick rods of the tool arm are flush, so as to ensure that the positions of the limiting grooves formed on each thick rod of the tool arm are the same.
