Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing and production, in particular to a structure of an arc-type large-angle rotating empty station. Background Art

[0002] Mold manufacturing is a complex and precise process encompassing numerous steps. From designing and planning the mold's structure and dimensions based on product requirements and usage scenarios, to carefully selecting materials that impact mold quality and lifespan, to utilizing a variety of advanced machine tools and processes, such as milling, grinding, and EDM, to ensure mold precision and surface quality.

[0003] Currently, automated molds are a new trend in stamping molds. However, the rotation angles of many parts during stamping make it difficult to achieve automated production. Small-angle rotations can be achieved through automatic guidance, but large-angle rotations cannot be achieved. Since the grippers are located at the front and rear sides of the machine tool, parts that rotate at large angles along the Y-axis are particularly difficult to achieve automated production. To this end, the utility model provides a structure with an arc-shaped large-angle rotation empty station. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a circular large-angle rotating empty workstation structure, which solves the problem that parts rotating at a large angle along the Y axis cannot be automatically produced because the clamping hands are on the front and back sides of the machine tool.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a structure of an arc-type large-angle rotating empty workstation, comprising a base plate, a rotating mechanism is provided on the top of the base plate, and the rotating mechanism comprises: a support assembly, the support assembly is arranged on the top of the base plate, the support assembly comprises two lower rotating inserts, and a rotating groove is provided on the top of the lower rotating insert; a driving assembly, the driving assembly comprises an upper rotating insert movably arranged inside the rotating groove, and the upper rotating insert is concentrically arranged with the rotating groove; a limiting assembly, the limiting assembly comprises electric push rods respectively fixedly mounted on the opposite side surfaces of the two lower rotating inserts, and the telescopic end of the electric push rod is fixedly mounted with a bayonet.

[0006] Preferably, the support assembly further comprises pad legs symmetrically fixedly mounted on the top of the base plate, a template is fixedly mounted between the tops of the two pad legs, and the two lower rotating inserts are symmetrically fixedly mounted on the top of the template.

[0007] Preferably, an anti-interference groove is provided on the front side of the lower rotating insert, and a pressure plate is symmetrically fixedly installed on the top of the lower rotating insert.

[0008] Preferably, the driving assembly also includes two pads symmetrically fixedly installed on the top of the base plate, a cylinder is rotatably provided on the top of the two pads, a fixed plate is rotatably provided on the telescopic end of the cylinder, a connecting plate is fixedly installed on the inner wall of the fixed plate, and the opposite side surfaces of the two connecting plates are fixedly connected to the outer surfaces of the two upper rotating inserts, and the outer surface of the upper rotating insert is provided with a guide groove that cooperates with the pressure plate.

[0009] Preferably, the limiting assembly further comprises a guide hole provided on the surface of the lower rotating insert and a plurality of pin holes provided on the surface of the upper rotating insert, the bayonet is slidably arranged inside the guide hole, and the bayonet is engaged with any one of the pin holes.

[0010] Preferably, a plurality of symbol-shaped inserts are fixedly mounted on the top of the template, and a positioning plate is fixedly mounted on the top of the upper rotating insert. Beneficial effects

[0011] The utility model provides a structure for an arc-shaped large-angle rotating idle station. Compared with the prior art, it has the following advantages:

[0012] (1) The structure of the arc-type large-angle rotating workstation can transmit the rotational force converted by the mutual expansion and contraction of the two cylinders to the upper rotating insert through the connecting plate, and the upper rotating insert rotates. Since there is no actual rotation axis, there is only a virtual rotation axis in the arc design, so the gripper will not interfere with the mold when entering and exiting from the front and back sides. It is through such design and operation that the problem of Y-axis rotation is successfully solved and the demand for large-angle rotation is met.

[0013] (2) The structure of the arc-shaped large-angle rotating empty station plays a role in guiding the bayonet through the fixed plate. At the same time, when the bayonet cooperates with the pin hole to limit the upper rotating insert, it can avoid excessive external pressure, which may cause the telescopic rod of the electric push rod to bend, thereby reducing the failure rate.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] This utility model provides two technical solutions:

[0021] Figure 1-Figure 4The first embodiment is shown: a structure of an arc-type large-angle rotating empty workstation, including a base plate 1, a rotating mechanism 2 is provided on the top of the base plate 1, and the rotating mechanism 2 includes: a support assembly 21, the support assembly 21 is arranged on the top of the base plate 1, the support assembly 21 includes two lower rotating inserts 213, and a rotating groove 214 is opened on the top of the lower rotating insert 213; a driving assembly 22, the driving assembly 22 includes an upper rotating insert 225 movably arranged inside the rotating groove 214, and the upper rotating insert 225 is concentrically arranged with the rotating groove 214; a limiting assembly 23, the limiting assembly 23 includes an electric push rod 231 respectively fixedly mounted on the opposite side surface of the two lower rotating inserts 213, and the telescopic end of the electric push rod 231 is fixedly mounted with a pin 232, the support assembly 21 also includes a pad leg 211 symmetrically fixedly mounted on the top of the base plate 1, a template 212 is fixedly mounted between the tops of the two pad legs 211, and the two lower rotating inserts 213 are symmetrically fixedly mounted At the top of the template 212, an anti-interference groove 215 is provided on the front side of the lower rotating insert 213, and a pressure plate 216 is symmetrically fixedly installed on the top of the lower rotating insert 213. The driving assembly 22 also includes two pads 221 symmetrically fixedly installed on the top of the base plate 1. The top of the two pads 221 is rotatably provided with a cylinder 222. By extending one of the two cylinders 222 and retracting the other, the rotation movement of the upper rotating insert 225 can be controlled. The telescopic end of the cylinder 222 is rotatably provided with a fixed plate 223. The inner wall of the fixed plate 223 is fixedly installed with a connecting plate 224. The rotational force converted by the mutual expansion and contraction of the two cylinders 222 can be transmitted to the upper rotating insert 225 through the connecting plate 224, and the upper rotating insert 225 rotates. The opposite side surfaces of the two connecting plates 224 are fixedly connected to the outer surfaces of the two upper rotating inserts 225, and the outer surface of the upper rotating insert 225 is provided with a guide groove 226 that cooperates with the pressure plate 216.

[0022] The selected length of the front cylinder 222 is smaller than that of the rear cylinder 222. The purpose is to ensure the normal rotation drive of the upper rotating insert 225. Through the setting of the pressure plate 216 and the cooperation of the guide groove 226, the upper rotating insert 225 can be restricted inside the rotating groove 214. Through the setting of the anti-interference groove 215, the front connecting plate 224 is prevented from interfering with the lower rotating insert 213 when the driving component 22 rotates forward, thereby increasing the rotation range of the upper rotating insert 225.

[0023] Figure 1-Figure 4A second embodiment is shown, the main difference from the first embodiment is that the limiting assembly 23 also includes a guide hole 233 opened on the surface of the lower rotating insert 213 and a plurality of pin holes 234 opened on the surface of the upper rotating insert 225, the locking pin 232 is slidably set inside the guide hole 233, and the locking pin 232 is engaged with any one of the pin holes 234, a plurality of symbol-shaped inserts 3 are fixedly installed on the top of the template 212, and a positioning plate 4 is fixedly installed on the top of the upper rotating insert 225.

[0024] The fixed plate 223 is provided to guide the bayonet 232. At the same time, when the bayonet 232 cooperates with the pin hole 234 to limit the upper rotating insert 225, it can avoid excessive external pressure, which may cause the telescopic rod of the electric push rod 231 to bend, thereby reducing the failure rate.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] During operation, the base plate 1, the pad leg 211, and the template 212 are processed and installed in turn. After that, the lower rotating insert 213 and the upper rotating insert 225 are processed and installed, and then the pressure plate 216, the connecting plate 224 and the cylinder 222 are installed. Then, the positioning plate 4 is processed and installed. Finally, the symbol insert 3 is installed and debugged on the machine. After adjusting the positioning, it is confirmed and debugged to the required rotation angle. After the above steps, after the above series of steps, the rotation of the part angle can be successfully realized. The limit plays a decisive role in this. It determines the angle of the part. At the same time, since there is no actual rotation axis, there is only a virtual rotation axis in the arc design, so the clamp will not interfere with the mold when entering and exiting from the front and back sides. It is through such design and operation that the problem of Y-axis rotation is successfully solved, and the demand for large-angle rotation is met, and the rotation angle can be adjusted at will according to actual needs.
