A device for detecting the coaxiality of a bottom mold

Abstract

This application discloses a device for detecting the coaxiality of a bottom mold, relating to the field of mold processing. It includes a base, on which a dial indicator is mounted. A column is mounted on the base, and a rotating support is rotatably mounted on the upper part of the column. A rotating platform is mounted on the upper part of the rotating support, and a bottom mold is placed on the rotating platform. A positioning rivet is installed at the lower center of the bottom mold. In this application, the rotating support rotates smoothly via a first thrust bearing and a second thrust bearing, driving the upper bottom mold to rotate. When the bottom mold rotates, if there is a misalignment between its central axis and the position of the positioning rivet, the side of the bottom mold will push the dial indicator head inward, causing a change in the percentage reading. This allows for rapid detection of the coaxiality between the bottom mold and the rivet.

Description

Technical Field

[0001] This application relates to the field of mold processing, and in particular to a device for detecting the coaxiality of a bottom mold. Background Technology

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Typically, a mold consists of two parts: an upper die and a lower die. A steel plate is placed between the upper and lower dies, and the material is formed under the action of a press. When the press opens, a workpiece determined by the mold shape is obtained, or corresponding waste material is removed. Workpieces ranging from small electronic connectors to large automotive dashboards can be formed using molds. Progressive dies are a set of molds that automatically move the workpiece from one station to another, obtaining the formed part at the last station. Mold processing technologies include: cutting dies, blanking dies, compound dies, extrusion dies, four-slide dies, progressive dies, stamping dies, and die-cutting dies.

[0003] Currently, the bottom mold assembly consists of multiple parts assembled together. Due to machining errors and inconsistent skill levels among assemblers, the positioning ties of the bottom mold and the bottom mold assembly are not on the same axis. This causes damage to the bottom mold when the mold is opened and closed. After each assembly, the bottom mold needs to be inspected on a lathe or coordinate measuring machine, which is time-consuming and inefficient. Utility Model Content

[0004] To address the issues of misalignment of the bottom mold and its component positioning ties due to machining errors and inconsistent skill levels among assemblers, which can damage the bottom mold during mold opening and closing and necessitate time-consuming and inefficient inspection on a lathe or coordinate measuring machine after each assembly, this application provides a device for detecting the coaxiality of the bottom mold.

[0005] The device for detecting the coaxiality of the bottom mold provided in this application adopts the following technical solution:

[0006] The device includes a base on which a dial indicator is mounted, a column on which a rotating support is rotatably mounted, a rotating platform on which a bottom mold is placed, and a positioning rivet at the lower center of the bottom mold.

[0007] By adopting the above technical solution, the rotating support rotates smoothly through the first thrust bearing and the second thrust bearing, which drives the upper bottom mold to rotate. When the bottom mold rotates, if the position of its central axis and the position of the positioning rivet are offset, the side of the bottom mold will push the measuring head to retract inward, and the pointer of the percentage measurement will change.

[0008] Preferably, a positioning vertical groove is provided in the middle of the rotating platform and the rotating support. The size of the positioning vertical groove is adapted to the size of the positioning rivet, and the positioning rivet is located inside the positioning vertical groove.

[0009] By adopting the above technical solution, the positioning rivets and positioning vertical grooves at the bottom of the bottom mold are aligned vertically, and then the bottom mold is gradually moved down so that the positioning rivets enter the interior of the positioning vertical grooves.

[0010] Preferably, the rotating support has an installation groove in the middle of its inner side, the diameter of the installation groove is larger than the diameter of the column, and the upper part of the column is located inside the installation groove.

[0011] By adopting the above technical solution, when the rotating support rotates, it rotates around the column as the center. The column is located inside the mounting groove, and it rotates smoothly with the first thrust bearing and the second thrust bearing, thereby improving the overall stability.

[0012] Preferably, a first thrust bearing is installed on the upper inner side of the mounting groove, and a second thrust bearing is installed on the lower inner side of the mounting groove. The rotating support is rotatably connected to the column through the first thrust bearing and the second thrust bearing.

[0013] By adopting the above technical solution, the rotating platform is rotated, which drives the rotating support to rotate. The rotating support rotates smoothly through the first thrust bearing and the second thrust bearing.

[0014] Preferably, a mounting base is installed on the base, a support column is installed on the mounting base, and the measuring dial indicator is installed on the upper part of the support column.

[0015] By adopting the above technical solution, the dial indicator is supported by a support column, and an adjustment mechanism can be installed on the upper part of the support column to adjust the position of the dial indicator.

[0016] Preferably, the measuring dial indicator is equipped with a measuring head, one end of which is attached to the upper side of the bottom mold.

[0017] By adopting the above technical solution, the side of the bottom mold will push the measuring head to retract inward, at which time the pointer of the percentage measurement will change, so as to quickly detect the coaxiality of the bottom mold and the rivet.

[0018] Preferably, two suction cup cylinders are installed at the lower part of the rotating platform, and one end of each suction cup cylinder is attached to the lower part of the bottom mold.

[0019] By adopting the above technical solution, the suction cylinder is activated, and the lower surface of the bottom mold is adsorbed and fixed by the suction cylinder, which facilitates the rotation of the bottom mold.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. In this application, the rotating support rotates smoothly through the first thrust bearing and the second thrust bearing, which drives the upper bottom mold to rotate. When the bottom mold rotates, if the position of its central axis and the position of the positioning rivet deviates from the coaxial position, the side of the bottom mold will push the measuring head to retract inward. At this time, the pointer of the measuring percentage will change, so that the coaxiality of the bottom mold and the rivet can be quickly detected.

[0022] 2. When the rotating support rotates, it rotates around the column, which is located inside the mounting groove. The rotation is smooth with the first thrust bearing and the second thrust bearing, thus improving the overall stability. Attached Figure Description

The upper mold is used to form the mold. The middle part of the rotating platform 14 and the rotating support 9 is provided with a positioning vertical groove 16. The size of the positioning vertical groove 16 is adapted to the size of the positioning pull pin 12. The positioning pull pin 12 is located inside the positioning vertical groove 16. The rotating support 8 rotates smoothly through the first thrust bearing 10 and the second thrust bearing 11, which drives the upper bottom mold 13 to rotate. When the bottom mold 13 rotates, if its central axis is offset from the position of the positioning pull pin 12, the side of the bottom mold 13 will push the measuring head 5 to retract inward. At this time, the pointer of the measuring percentage 4 will change, so that the coaxiality of the bottom mold and the pull pin can be quickly detected.

[0029] Please refer to Figure 1 and Figure 3 The rotating support 8 has an installation groove 9 in the middle of its inner side. The diameter of the installation groove 9 is larger than the diameter of the column 7. The upper part of the column 7 is located inside the installation groove 9. A first thrust bearing 10 is installed on the upper inner side of the installation groove 9, and a second thrust bearing 11 is installed on the lower inner side of the installation groove 9. The rotating support 8 is rotatably connected to the column 7 through the first thrust bearing 10 and the second thrust bearing 11. When the rotating support 8 rotates, it rotates around the column 7 as the center. The column 7 is located inside the installation groove 9. By rotating smoothly with the first thrust bearing 10 and the second thrust bearing 11, the overall stability is improved.

[0030] Please refer to Figure 2 A mounting base 2 is installed on the base 1, and a support column 3 is installed on the mounting base 2. A dial indicator 4 is installed on the upper part of the support column 3, and a measuring head 5 is installed on the dial indicator 4. One end of the measuring head 5 is attached to the upper side of the bottom mold 13. When the bottom mold 13 rotates, if its central axis is offset from the position of the positioning rivet 12, the side of the bottom mold 13 will push the measuring head 5 to retract inward. At this time, the pointer of the measuring percentage 4 will change, which shows the coaxiality of the bottom mold 13 and the positioning rivet 12.

[0031] Please refer to Figure 1 and Figure 2Two suction cylinders 15 are installed on the lower part of the rotating platform 14. One end of the suction cylinder 15 is attached to the lower part of the bottom mold 13. When the suction cylinder 15 is activated, the lower surface of the bottom mold 13 is attached and fixed. At this time, the rotating platform 14 is rotated, which drives the rotating support 8 to rotate.

[0032] The implementation principle of the bottom mold coaxiality detection device in this application embodiment is as follows: In actual use, firstly, the positioning pull pin 12 and the positioning vertical groove 16 at the bottom of the bottom mold 13 are aligned vertically. Then, the bottom mold 13 is gradually moved down so that the positioning pull pin 12 enters the interior of the positioning vertical groove 16. At this time, the suction cylinder 15 is activated to adsorb and fix the lower surface of the bottom mold 13. Then, the rotating platform 14 is rotated, which drives the rotating support 8 to rotate. The rotating support 8 rotates smoothly through the first thrust bearing 10 and the second thrust bearing 11, which drives the upper bottom mold 13 to rotate. When the bottom mold 13 rotates, if the position of its central axis and the position of the positioning pull pin 12 are offset, the side of the bottom mold 13 will push the measuring head 5 to retract inward. At this time, the pointer of the percentage measurement 4 will change, so that the coaxiality of the bottom mold 13 and the positioning pull pin 12 can be quickly detected.
