Description

Technical Field

[0001] This utility model relates to the technical field of stamping devices, specifically a moving locking structure for a stamping device. Background Technology

[0002] Traditional stamping machines have fixed, immovable platforms, which means the position of the worktable is also fixed and its area cannot be adjusted. This makes them unsuitable for stamping large sheet metal. If a movable platform is used, it is difficult to guarantee that the platform will not move under the vibration of the stamping force when it is stationary. Therefore, ensuring the stamping accuracy of a movable platform when it is stationary is also a problem that needs to be solved. Utility Model Content

[0003] This invention provides a movable locking structure for a stamping device, which can solve the problem that existing traditional stamping devices do not have a machine base that can be moved and adjusted.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a moving locking structure for a stamping device, comprising a base platform, a slide rail on the upper side of the base platform, a moving machine platform slidably mounted on the upper side of the slide rail, a hollow center in the base platform, and a lead screw horizontally mounted inside the hollow center, a motor at one end of the lead screw, a lead screw nut connected to the moving machine platform sleeved on the lead screw, and multiple locking components mounted on the lower end of the moving machine platform, wherein the locking components are locked to the base platform when the moving machine platform stops moving, and disengaged from the base platform when the lead screw rotates. The precise movement of the moving machine platform can be controlled by the cooperation of the lead screw and the motor, while the locking components lock the stopped moving machine platform, preventing movement during stamping operations and ensuring stamping accuracy.

[0005] Preferably, the locking components are arranged in a rectangular array at the lower center of the mobile platform, which can lock and position the mobile platform over a relatively large range.

[0006] Preferably, the locking assembly includes a hydraulic cylinder and a rotating shaft seat mounted on the lower end face of the hydraulic cylinder. The rotating shaft seat is rotatably connected to the first end of the connecting rod. The lower end extension shaft of the hydraulic cylinder is rotatably connected to the first end of the locking pressure plate. The second end of the locking pressure plate extends to the side of the hollowed-out part in the middle of the base platform. The second end of the connecting rod is rotatably connected to the middle of the locking pressure plate. When the extension rod of the hydraulic cylinder extends downward, the second end of the locking pressure plate moves upward to press against the base platform for locking. The hydraulic cylinder, locking pressure plate and connecting rod form a lever pressing structure, which, in conjunction with the base platform, can apply a downward pulling force to the moving machine platform to achieve locking of the moving machine platform.

[0007] Preferably, the two sides of the hollowed-out center of the base are equipped with baffles. When the second end of the locking plate moves upward, it contacts the baffles and presses them together to lock. The baffles can be disassembled and replaced, which is low-cost and reduces the damage to the base caused by the locking plate.

[0008] Preferably, the slide rails are arranged on both sides of the central hollowed-out area on the base platform, and at least two sliders are installed on each slide rail. The mobile machine platform is mounted on the sliders, which can improve the smoothness of the movement of the mobile machine platform.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] With a simple structure, the moving machine can be precisely controlled by the cooperation of the lead screw and the motor. At the same time, the moving machine is locked when it stops, so that it will not move during the stamping operation, thus ensuring the stamping accuracy. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figure 1-3As shown, this utility model provides the following technical solution to solve the problem that existing traditional stamping devices lack a movable and adjustable machine base: a movable locking structure for a stamping device, including a base 1, a slide rail 7 on the upper side of the base 1, a movable machine base 2 slidably mounted on the upper side of the slide rail 7, a hollow center in the base 1, and a lead screw 4 horizontally installed inside the hollow center, a motor 3 at one end of the lead screw 4, and a lead screw nut 5 connected to the movable machine base 2 fitted on the lead screw 4. Multiple locking components 6 are installed at the lower end of the movable machine base 2. The locking components 6 are locked to the base 1 when the movable machine base 2 stops moving, and disengage from the base 1 when the lead screw 4 rotates. The precise movement of the movable machine base 2 can be controlled by the cooperation of the lead screw 4 and the motor 3, while the locking components 6 lock the stopped movable machine base 2, preventing it from moving during stamping operations and ensuring stamping accuracy.

[0018] Specifically, the length of the base platform 1 is greater than the length of the movable platform 2, the movable platform 2 has sufficient travel, and the lead screw 4 and lead screw nut 5 have a self-locking function, which can lock the movable platform 2 to a certain extent. The locking component 6 can have various structures, such as a hydraulic cylinder pressing structure, in which the hydraulic cylinder drives the pressure plate to press the base platform 1 to achieve locking. A toothed meshing structure can also be used for locking.

[0019] In this embodiment, as Figure 3 As shown, there are four locking components 6 arranged in a rectangular array at the lower center of the mobile platform 2. They can lock and position the mobile platform 2 over a relatively large area. All four locking components 6 can be set within the hollowed-out area in the middle of the base platform 1. Two on one side lock one side of the hollowed-out area, and two on the other side lock the other side of the hollowed-out area.

[0020] As a specific embodiment of the locking component 6, such as Figure 2 As shown, the locking assembly 6 includes a hydraulic cylinder 61 and a rotating shaft seat 62 mounted on the lower end face of the hydraulic cylinder 61. The rotating shaft seat 62 is rotatably connected to the first end of the connecting rod 65. The lower end of the hydraulic cylinder 61 extends downward and is rotatably connected to the first end of the locking pressure plate 64. The second end of the locking pressure plate 64 extends to the side of the hollowed-out part in the middle of the base platform 1. The second end of the connecting rod 65 is rotatably connected to the middle of the locking pressure plate 64. When the extension rod of the hydraulic cylinder 61 extends downward, the second end of the locking pressure plate 64 moves upward and presses the base platform 1 to lock it. The hydraulic cylinder 61, the locking pressure plate 64 and the connecting rod 65 form a lever pressing structure. In cooperation with the base platform 1, it can apply a downward pulling force to the moving machine platform 2 to lock the moving machine platform 2.

[0021] Meanwhile, in order to reduce maintenance and manufacturing costs, baffles 63 are installed on both sides of the hollowed-out middle part of the base 1. When the second end of the locking plate 64 moves upward, it contacts the baffles 63 and presses them together to lock. The baffles 63 can be disassembled and replaced, which is low-cost and reduces the damage of the locking plate 64 to the base 1.

[0022] To make the sliding of the mobile platform 2 smoother, the slide rails 7 are set on both sides of the central hollowed-out part of the base platform 1. At least two sliders 8 are installed on each slide rail 7. The mobile platform 2 is mounted on the sliders 8, which can improve the smoothness of the movement of the mobile platform 2.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
