DETAILED DESCRIPTION
[0013] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1 、 2 As shown, a tool holder center positioning and stabilization mechanism in this embodiment includes a base, which includes a bottom plate 12 and a vertical plate 3. The vertical plate 3 is fixed to the center of the top surface of the bottom plate 12. The bottom plate 12 has two through-holes, symmetrically located on either side of the vertical plate 3. A second self-lubricating bearing 7 is positioned in each through-hole. A cylinder bracket is positioned on the side of the vertical plate 3. A vertically arranged cylinder 5 is positioned in the center of the cylinder bracket. The extension rod of the cylinder 5 extends through the cylinder bracket. The extension rod of the cylinder 5 is fixedly connected to a lifting block. Guide posts 1 are symmetrically positioned at the bottom of the lifting block. Guide sleeves 10 are also symmetrically positioned on the side of the vertical plate 3. The guide sleeves 10 match the guide posts 1 and each of the first self-lubricating bearings 6 is positioned in each guide sleeve. A gap is provided between the bottom end of the guide sleeves 10 and the bottom plate 12. A positioning bracket 8 is fixedly connected to the side of the tool holder 9. The positioning bracket 8 is positioned in the gap between the bottom end of the guide sleeve 10 and the bottom plate 12. The positioning bracket 8 has symmetrical positioning holes, and the gap between the two positioning holes matches the gap between the two guide posts 1. The oil cylinder 5 drives the lifting block to move up and down, driving the guide column 1 to move up and down synchronously, so that the guide column 1 passes through the first self-lubricating bearing 6, the positioning hole and the second self-lubricating bearing 7 in sequence, so that the guide column 1 limits the positioning bracket 8 and then fixes the tool holder; or the guide column leaves the second self-lubricating bearing, the positioning hole and the first self-lubricating bearing in sequence, so that the guide column is separated from the positioning bracket.
[0015] The lifting block comprises a V-shaped block 11 , a horizontally arranged support plate 2 is symmetrically arranged on the top of the V-shaped block 11 , and a guide column 1 is fixed to the bottom of the support plate 2 by bolts.
[0016] The first self-lubricating bearing 6 is fixed in the guide sleeve 10 by means of a fastening screw, and the guide sleeve 10 guides the guide column 1 when it is raised or lowered. The second self-lubricating bearing 7 is fixed in the through hole by means of a fastening screw.
[0017] The base plate is fixedly connected to the foundation via chemical bolts.
[0018] The tool holder moves out of the production line, and the oil cylinder extends the rod to drive the lifting block to descend, driving the guide column to move vertically downward. The guide column passes through the guide sleeve and the positioning bracket in sequence and is arranged in the second self-lubricating bearing, so that the positioning bracket is fixedly connected to the base, thereby positioning the tool holder and setting this place as the center position of the tool holder.
[0019] This application is easy to operate. The guide column passes through the positioning hole of the positioning bracket to limit the positioning bracket, and then positions the tool holder, providing center positioning for automatic tool arrangement and tool changing equipment; it achieves tool holder stability, improves tool changing accuracy, and improves production quality.
[0020] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
