Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of linear modules, in particular to a mounting unit applied to a linear slide. Background Art
[0002] Slide devices are widely used in industrial machines due to their linear movement characteristics. The sliding unit can carry the working mechanism and move linearly along the linear slide rail, which is conducive to calibration and operation. The sliding unit mainly includes a linear track, a sliding unit, and a drive module. The drive module drives the sliding unit to move linearly in the track groove of the linear track. In existing slide devices, since the sliding unit needs to be equipped with a nut and a screw of the drive module, the nut is generally fixed laterally in the slide seat of the sliding unit through a flange and a locking part. The nut installation structure is complex and occupies a large amount of space, which greatly reduces the space for oil circuit design, so that the slide device cannot be well lubricated, resulting in reduced operating efficiency and increased probability of component damage.
[0003] Patent document CN207740349U discloses a sliding unit and slide assembly that utilizes a flangeless nut without a flange structure to increase the available space within the slide, particularly allowing for more room for oil circuits. This improves lubrication between the sliding unit, the screw, and the linear track, thereby increasing operational efficiency and reducing the risk of component damage. Furthermore, a positioning post, coupled with first and second positioning holes, secures the slide relative to the flangeless nut. However, the patent document describes a weak connection between the positioning post and the flangeless nut, resulting in slow assembly and disassembly. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mounting unit for a linear slide to improve the slope of assembly and disassembly.
[0005] The technical solution of the present utility model is: an installation unit applied to a linear slide, comprising a slide seat, a sleeve inserted in the slide seat and a positioning pin, the slide seat is provided with a first positioning hole, the sleeve is provided with a second positioning hole, the diameter of the first positioning hole is larger than the second positioning hole, the positioning pin is inserted into the second positioning hole from the first positioning hole, so that the sleeve and the slide seat are fixed, the positioning pin is integrally formed from top to bottom with a first mounting portion, a positioning portion and a second mounting portion, the diameter of the positioning portion is smaller than the first mounting portion, and the diameter of the positioning portion is larger than the second mounting portion.
[0006] It can be seen from the above scheme that the positioning pin is inserted into the first positioning hole and the second positioning hole to fix the sliding sleeve and the sliding seat. The positioning pin is positioned and installed in the sliding seat at one time, which reduces the assembly and disassembly processes and facilitates assembly and disassembly. The diameter of the first positioning hole is larger than that of the second positioning hole. The contact area between the sliding sleeve and the positioning pin is increased, and the connection strength between the two is increased to reduce wear and avoid gaps. The first mounting portion is used to achieve locking with the sliding seat, the positioning portion is used to achieve positioning and limiting of the positioning pin in the sliding seat, and the second mounting portion is used to achieve locking and positioning between the positioning pin and the sliding sleeve.
[0007] The first positioning hole includes a first internally threaded portion and a first non-threaded portion, wherein the inner diameter of the first internally threaded portion is larger than that of the first non-threaded portion. Therefore, the first internally threaded portion is used to achieve locking and fixing between the slide and the positioning pin, while the first non-threaded portion is used to achieve position limiting between the slide and the positioning pin.
[0008] The first mounting portion is provided with an external thread, which is threadedly engaged with the first internal thread portion. As can be seen, due to the integrated structure of the thread and the positioning pin, the threaded portion is subjected to radial force, reducing the gap between the pin and the pin hole, and increasing the repeatable positioning accuracy of the module.
[0009] The second mounting portion is provided with an external thread, the second positioning hole is provided with an internal thread, and the second mounting portion is threadedly matched with the second positioning hole.
[0010] An outer diameter of the positioning portion is equal to an inner diameter of the first non-threaded portion.
[0011] A hexagonal nut hole is provided in the positioning pin, which is used to install the positioning pin in the slide seat. BRIEF DESCRIPTION OF THE DRAWINGS

The slide 1 is provided with a first positioning hole 4, and the sleeve 2 is provided with a second positioning hole 5. The diameter of the first positioning hole 4 is larger than that of the second positioning hole 5. The positioning pin 3 is inserted into the second positioning hole 5 from the first positioning hole 4 to fix the sleeve 2 to the slide 1. The positioning pin 3 is integrally formed with a first mounting portion 31, a positioning portion 32 and a second mounting portion 33 from top to bottom. The diameter of the positioning portion 32 is smaller than that of the first mounting portion 31, and the diameter of the positioning portion 32 is larger than that of the second mounting portion 33.
[0018] In this embodiment, there is an interference fit between the positioning pin 3 and the first positioning hole 4 and the second positioning hole 5. The upper surface of the slide 1 is arched and provided with a sliding surface. The slide 1 is provided with blocks extending upward on both sides of the sliding surface. The slide 1 is provided with a through hole 11 along the length direction. The slide 2 is arranged in the through hole 11. The slide 1 is provided with an oil passage hole above the through hole 11. The sleeve 2 is arranged in a columnar shape. A mounting through hole coaxial with the through hole 11 is provided in the sleeve 2. The second positioning hole 5 is arranged as a blind hole. The sleeve 2 is a nut without a flange structure.
[0019] The first positioning hole 4 includes a first internal threaded portion 41 and a first non-threaded portion 42 disposed below the first internal threaded portion 41 . The inner diameter of the first internal threaded portion 41 is greater than that of the first non-threaded portion 42 .
[0020] The first mounting portion 31 is provided with an external thread, and the first mounting portion 31 is threadedly engaged with the first internal thread portion 41.
