Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a core clamping device. Background Technology

[0002] like Figure 1 It is a core with an overall triangular ring structure, constructed from multiple stacked metal sheets. During assembly, a fixture is used to grip the core and move it above the housing for assembly. For example... Figure 2 and Figure 3 The image shows a clamping device in an existing structure. It uses a cylinder to drive two contoured clamping blocks to close inward and clamp the core. This clamping structure design has the following drawbacks: 1. After use, it was found that the core is easily deformed due to the inward clamping force, and the edges of the thin sheets forming the core may break; 2. The clamping of the core with the triangular ring structure by the two contoured clamping blocks is not stable enough, and there is a risk that the core may fall off during transfer and assembly.

[0003] Therefore, how to design a core clamping device with a simpler and more reasonable structure, a more reasonable clamping design to better avoid damage to the core, and improved clamping stability has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a core clamping device with a simpler and more reasonable structural design, a more reasonable clamping design to better avoid damage to the core, and to improve clamping stability.

[0005] To achieve the above objectives, this utility model provides a core clamping device, characterized in that: it includes a vertically arranged mounting plate, a mounting disk is provided on the front side of the lower end of the mounting plate, the upper end of the mounting disk forms a rotating mounting end and is connected to a horizontal rotating drive mechanism at the upper end of the mounting plate; three vertically downwardly arranged elongated mounting support plates are installed at intervals along the circumferential direction below the mounting disk; a vertically downwardly arranged clamping cylinder is installed on the lower end of each mounting support plate, and a vertically arranged clamping block is installed on each of the two drive ends of the clamping cylinder, and the clamping cylinder can drive the two pairs of clamping blocks to close inward and clamp each on the inner and outer walls of the core.

[0006] Thus, in the aforementioned seed core clamping device, three vertically downward-facing elongated mounting plates are set on the mounting plate, and clamping cylinders are installed on the mounting plates. The clamping cylinders drive pairs of clamping blocks to close inward and clamp onto the inner and outer walls of the seed core. When clamping the seed core, the inner and outer walls of the seed core are subjected to force, resulting in a more even clamping force and better preventing damage to the seed core. Furthermore, the clamping stability is higher. Secondly, the horizontal rotation drive mechanism can drive the mounting plate and the components below to rotate, allowing for better adjustment of the clamping position of the seed core, making the design more rational.

[0007] As an optimization, the clamping cylinder has two vertically downward-arranged cylinder rods, each forming the drive end; the clamping block includes a clamping block upper section located outside the cylinder rod, and a vertically arranged mounting groove is provided on the inner side of the clamping block upper section, so that the corresponding cylinder rod is fitted in the mounting groove; the clamping block upper section also has two vertically spaced screw holes for arranging connecting screws, so that the connecting screws can be threaded onto the cylinder rod.

[0008] In this way, the structural design of the clamping block is more reasonable, which allows the upper part of the clamping block to better cooperate with the cylinder rod of the clamping cylinder and be installed and fixed together.

[0009] As an optimization, the clamping block also includes a lower clamping block section integrally formed at the lower end of the upper clamping block section; and each of the lower sections of the clamping block section has a chamfered structure on the inner side of the lower end.

[0010] In this way, the design of the lower section of the clamping block is more reasonable, making it easier to touch the edge of the core when clamping the core.

[0011] Furthermore, the cross-sectional dimensions of the lower section of the clamping block are set to be larger than those of the upper section of the clamping block; and the inner surface of the lower section of the clamping block is located on the same surface as the inner surface of the cylinder rod.

[0012] Furthermore, the upper end of the mounting plate is bent horizontally to form a mounting block, which is connected to the mounting plate by screws.

[0013] As an optimization, the horizontal rotation drive mechanism includes a servo motor mounted on the upper end of the mounting plate; a drive shaft is mounted below the servo motor, and the upper end of the drive shaft is connected to the motor shaft of the servo motor via a coupling; the lower end of the drive shaft is connected to the mounting plate.

[0014] In this way, the horizontal rotation drive mechanism uses a servo motor, which allows for higher precision control; and by setting up a drive shaft and coupling, it can be better connected to the mounting plate for transmission.

[0015] Furthermore, the mounting plate includes an upper half and a lower half; the upper half of the mounting plate is connected to the drive shaft, and the lower half of the mounting plate is connected to the upper end of the mounting bracket.

[0016] As an optimization, a mounting base is provided on the mounting plate, and the mounting base is provided with a vertically arranged mounting hole, so that the drive shaft passes through the mounting hole of the mounting base, and a deep groove ball bearing is provided between the drive shaft and the mounting base.

[0017] In this way, by setting up a mounting base and a deep groove ball bearing, the drive shaft can be installed more effectively, improving precision.

[0018] As an optimization, it also includes a support plate disposed on the front side of the mounting base plate, and a vertical movement control mechanism for the support plate is provided between the mounting base plate and the support plate to control the vertical position of the support plate on the mounting base plate; an intermediate plate is installed on the front side of the support plate, and the mounting plate is installed on the intermediate plate.

[0019] In this way, by setting up a mounting base plate, a support plate, and an intermediate plate, and placing the mounting plate on the intermediate plate, the vertical position of the entire clamping device can be better controlled.

[0020] As an optimization, the two sides of the lower end of the middle plate protrude outward to form extension plate segments, making the middle plate as a whole have an inverted T-shaped structure design, and the mounting plate is installed on one of the extension plate segments.

[0021] This makes the structural design of the middle plate simpler and the layout easier to set up.

[0022] As an optimization, the vertical movement control mechanism of the support plate includes a vertical cylinder mounted on the mounting base plate and arranged vertically downward; a vertically arranged guide rail is provided on the vertical cylinder, a guide block is provided on the support plate, the guide block is provided with a guide groove and cooperates with the guide rail; a horizontally rearward fixed plate is provided at the lower end of the support plate, and the piston rod end of the vertical cylinder is connected to the fixed plate.

[0023] In this way, the design of the vertical movement control mechanism of the support plate is simpler and more reasonable, the layout design is more convenient, and the vertical structure layout is more compact.

[0024] In summary, the aforementioned core clamping device features a simpler and more reasonable structural design, a more rational clamping design that better avoids damage to the core, and improved clamping stability. Attached Figure Description
