Description

Technical Field

[0001] The utility model relates to the technical field of cylinder limiting technology, in particular to a rotary quick-change limiting device. Background Art

[0002] In the field of modern mechanical design, cylinder limit can be achieved by mechanical or electrical means. Mechanical limit is generally achieved by adjusting the cylinder stroke. Electrical limit detects the position of the cylinder through a sensor or switch. When the cylinder reaches the limited position, the electrical signal triggers the cylinder to stop moving. In the pneumatic system, the setting of cylinder limit has an important impact on working accuracy and safety. Reasonable cylinder limit can prevent the cylinder from colliding with workpieces or other equipment, reduce the occurrence of failures, and improve production efficiency. The cylinder limit is a setting for the range of cylinder movement, which is of great significance to the normal operation of the pneumatic system. The cylinder limit plays an important role in industrial production. It can ensure that the cylinder operates within the normal working range and avoid mechanical failures and equipment damage caused by exceeding the stroke. At the same time, it can also increase the safety and stability of the cylinder and improve the working efficiency and production quality of the equipment.

[0003] The existing production mode of mechanical processing is mainly reflected in the backward application of tooling, low efficiency, and long clamping and alignment time when manually processing parts. Especially when the tooling is frequently changed for single-piece or small-batch production, most of the time is spent on installation and alignment. In a mechanical device, if a cylinder has multiple positions for its extension action, and each position requires a certain position accuracy, then different limit points are required when moving to different positions. In this case, it is necessary to change the limit every time a cylinder extension action is changed, and it is necessary to debug and find the accuracy again, which undoubtedly wastes a lot of time and energy and greatly reduces production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rotary quick-change limit device, which utilizes a rotary quick-change structure to replace the limit, saves time and cost, does not need to readjust the position of the limit point, ensures equipment accuracy, and improves production efficiency.

[0005] Based on the above problems, the technical solution proposed by the utility model is a rotary quick-change limit device, comprising a base plate, a turntable rotatably connected to the base plate, adjustment bolts of different lengths circumferentially distributed on the turntable, and a fixing mechanism for fixing the turntable, wherein U-shaped grooves are arranged between adjacent adjustment bolts on the turntable, and the fixing mechanism cooperates with the U-shaped grooves to realize the positioning of the turntable.

[0006] The U-shaped grooves are opened outwards and are centrally symmetrically distributed on the turntable.

[0007] Among them, the bottom plate is a rectangular column with chamfered corners, the fixing mechanism is a plug-in pin, a chamfered bottom surface is integrally connected to a protrusion, a connecting hole is set in the center of the protrusion, and the plug-in pin passes through the connecting hole and can extend into the U-shaped groove.

[0008] Furthermore, a surface of the protrusion opposite to the rotating disk is configured as an arc-shaped surface.

[0009] Wherein, on the side surface of the turntable, a corresponding number is set at the upper position corresponding to each adjusting bolt.

[0010] The utility model also includes a discharge bolt located at the center of the bottom plate and the rotating disk, and the rotating disk rotates around the discharge bolt relative to the bottom plate.

[0011] The advantages and beneficial effects of the utility model are as follows: the utility model has a simple structure, is easy to design, machine process, assemble and install, and is also easy to maintain and repair after the structure is put into use in the equipment, thereby reducing the cost of machining.

[0012] The structure of this invention is mainly improved by using the quick-change structure to correspond to the replacement of the cylinder extension stroke. The cylinder limit device adopts an adjustment bolt, which has accurate limit, simple structure, and convenient limit accuracy. This design combines the quick-change structure with the cylinder limit, adjusts the position accuracy of the limit point in advance, and uses the quick-change device to perform different extension amounts required by the equipment cylinder. If the cylinder needs to extend to several stroke limit points, several adjustment bolts are designed for adjustment. After the position accuracy of each adjustment bolt is adjusted, the adjustment bolt can be quickly replaced by directly rotating the turntable. Using the rotating quick-change structure to replace the limit, first of all, it saves time cost, and secondly, there is no need to adjust the position of the limit point again, which ensures equipment accuracy and improves production efficiency.

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, the technical solution proposed by the utility model is a rotary quick-change limit device, comprising a base plate 1, a turntable 2 rotatably connected to the base plate 1, adjustment bolts 4 of different lengths circumferentially distributed on the turntable 2, and a fixing mechanism for fixing the turntable 2, U-shaped grooves 9 are arranged between adjacent adjustment bolts 4 on the turntable 2, and the fixing mechanism cooperates with the U-shaped grooves 9 to realize the positioning of the turntable 2

[0019] The U-shaped grooves 9 are opened outwards and are distributed on the turntable 2 in a centrally symmetrical manner.

[0020] The base plate 1 is a rectangular column with chamfers 6 at two corners. The fixing mechanism is a plug pin 3. The bottom surface of the chamfer 6 on one side is integrally connected to a protrusion 7. A connecting hole is set in the center of the protrusion 7. The plug pin 3 passes through the connecting hole and can extend into the U-shaped groove 9.

[0021] The surface of the protrusion 7 opposite to the rotating disk 2 is configured as an arc-shaped surface.

[0022] On the side surface of the turntable 2 , a corresponding number is set at the upper position corresponding to each adjusting bolt 4 .

[0023] It also includes a discharge bolt 5 located at the center of the base plate 1 and the turntable 2. The turntable 2 rotates around the discharge bolt 5 relative to the base plate 1.

[0024] The opposite sides of the base plate 1 are provided with mounting holes 8 for mounting the entire device at a certain position.

[0025] If the part to be limited is made of soft materials such as aluminum, an iron sheet should be attached to the limited position or an external hexagonal nut should be connected to avoid excessive collisions with the adjusting bolt 4, which may cause aluminum deformation and affect the limiting accuracy.

[0026] The present application needs to adjust the position accuracy of the limit point in advance, and use the quick-change device to achieve the different extension amounts required by the equipment cylinder. If the cylinder needs to extend to several travel limit points, several adjustment bolts 4 are designed for adjustment. After the position accuracy of each adjustment bolt 4 is adjusted, the quick change of the adjustment bolt 4 can be achieved by directly rotating the turntable 2.

[0027] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
