Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic element limiting, in particular to a limiting block for a pneumatic element. Background Art

[0002] Pneumatic components are actuators that use compressed air as their working power and are currently widely used in the field of automation control.

[0003] Pneumatic slides are a common type of pneumatic component. Pneumatic slides are mostly composed of a base plate, a cylinder, a linear guide and a slide. The base plate is used to fix the slide, the cylinder is installed on the base plate, the output end is connected to the slide, the linear guide is installed on the base plate, and the linear slider it is equipped with is connected to the slide by bolts. Equipment, fixtures, etc. can be installed on the slide. When working, the cylinder extends or retracts, and with the cooperation of the linear guide, the slide can be moved, and the fixture or equipment can be moved.

[0004] In order to ensure that the slide is limited when it stops and improve safety, most pneumatic slides have limit devices on both sides of the slide. The traditional way of setting the limit device is to install limit blocks on both sides of the linear guide rail where the slide is installed for limiting. However, in order to prevent the slide from directly impacting the limit blocks, rubber buffers will be installed on the limit blocks. Therefore, when the cylinder is fully extended or retracted, when the slide stops, it will need to overcome the resistance of the rubber buffer before stopping to achieve deceleration and avoid direct collision with the limit blocks, which would cause damage to the limit blocks. However, the rubber buffers have low pressure resistance and a short service life. When replaced, they are mostly replaced as a whole, which increases the cost of use. Utility Model Content

It can be understood that the above scheme can reduce the use cost, facilitate use and promotion.

[0024] In this embodiment, the limit block body 101 can be used to limit the slide seat of the pneumatic slide.

[0025] Among them, the limit block body 101 is provided with a mounting hole 1011 and a main semicircular slide 1012, the mounting hole 1011 passes through the limit block body 101 and is located on both sides of the bottom of the limit block body 101, and the main semicircular slide 1012 is provided on the top of the limit block body 101; the mounting hole 1011 facilitates the installation of the limit block body 101 by bolts, and the limit block body 101 is installed on both sides of the linear guide rail of the pneumatic slide table to limit the slide seat, and the main semicircular slide 1012 facilitates the sliding of the abutment rod 103.

[0026] The cover plate 102 has an auxiliary semicircular slide 1021, which is located on the side of the cover plate 102 close to the main semicircular slide 1012. The cover plate 102 is detachably connected to the limit block body 101 and is located on the top of the limit block body 101. The abutment rod 103 is slidably connected to the main semicircular slide 1012 and the auxiliary semicircular slide 1021 respectively, and is located on the side of the limit block body 101 close to the cover plate 102. The spring 104 is arranged in the main semicircular slide 1012 and the auxiliary semicircular slide 1021, and is located on the rear side of the abutment rod 103. After the auxiliary semicircular slide 1021 is installed on the limit block body 101 by bolts, it forms a circular slide cavity with the main semicircular slide 1012 to facilitate the sliding of the abutment rod 103. The cross-section of the abutment rod 103 is T-shaped, the front head is semicircular, and the rear disc end can slide in the circular slide cavity formed by the main semicircular slide 1012 and the auxiliary semicircular slide 1021. The front side of the cover plate 102 has a limiting portion to limit the sliding of the abutment rod 103. The spring 104 is a coil spring, which is directly arranged in the circular slide cavity formed by the main semicircular slide 1012 and the auxiliary semicircular slide 1021, and is limited after the cover plate 102 is installed.

[0027] Secondly, the mounting hole 1011 is a countersunk hole. The mounting hole 1011 is set as a countersunk hole to prevent the fixing bolt of the limit block body 101 from interfering with other components and affecting assembly and operation.

[0028] Then, the limit block body 101 further has first mounting protrusions 1013, and the first mounting protrusions 1013 are located on both sides of the limit block body 101.

When using it, first install the limit block body 101 on both sides of the linear guide rail of the pneumatic slide. When the cylinder moves to extend or retract, the slide seat will squeeze the abutment rod 103, and the abutment rod 103 slides under the force and compresses the spring 104. After the spring 104 is compressed, it will provide a reaction force to perform deceleration and buffering, thereby protecting the limit block body 101. After the spring 104 is fully retracted, the cylinder is fully extended or retracted, and the side of the slide seat just abuts against the limit block body 101. On the end face, the limit can be performed by the limit block body 101. At the same time, after the cylinder is reversed, the gas delivery continues, and its output end will form a pulling force or a thrust on the slide, so that the slide will not rock back and forth and stop stably. Furthermore, the limit block body 101, the cover plate 102, the abutment rod 103 and the spring 104 are installed in combination. If one of them is damaged, it can be replaced separately, which is beneficial to reduce the use cost. Compared with the rubber buffer, the service life of the spring 104 is also longer, so that when in use, when the pneumatic component is limited in work, it is beneficial to reduce the use cost and facilitate use and promotion.
