Description

Technical Field

[0001] This utility model relates to the field of slide ram technology, and in particular to a slide ram of linear guide rail and hydrostatic composite guide rail. Background Technology

[0002] Rams are widely used in the field of mechanical manufacturing, such as the machining of planes and grooves of various parts. For example, in automobile manufacturing, they can be used to machine the planes of parts such as engine blocks and gearbox housings; in mold manufacturing, they can be used to machine the plane parts such as cavities and cores of molds.

[0003] The movement of the ram is guided and supported by guide rails. For an existing ram structure, see "A Linear Guide Rail Positioning Mechanism" in publication number CN212145308U, which includes four linear guide rails and a ram, with the four linear guide rails respectively located at the four corners of the ram.

[0004] While the existing ram structure can achieve high-precision movement guidance, its load-bearing capacity is relatively poor. Utility Model Content

[0020] like Figure 1 , 2 As shown, this utility model discloses a ram of a linear guide and a hydrostatic composite guide, including a square ram body 1, a slide seat 2, a guide rail assembly disposed between the ram body 1 and the slide seat 2, a cylinder bracket 5 disposed on the ram body 1, a cylinder 6 disposed between the slide seat 2 and the cylinder bracket 5, a main shaft 3 disposed at one end of the ram body 1, and a drive assembly for driving the main shaft. The ram body 1 includes a first vertical plate 11, a second vertical plate 12, a third vertical plate, a fourth vertical plate, a top plate 13, and a bottom plate. The guide rail assembly includes a first linear guide 31 disposed on the second vertical plate 12 and the fourth vertical plate, two second linear guides 32 disposed on the third vertical plate, and two hydrostatic guides 33 disposed on the second vertical plate 12 and the fourth vertical plate, respectively.

[0021] The aforementioned ram structure employs both linear guides and hydrostatic guides for support and guidance, satisfying both high precision requirements and high load-bearing capacity.

[0022] There are several ways to configure the drive assembly. For example, an existing structure can be used, including a drive motor, a gearbox, and a coupling. In this case, the drive motor and gearbox are located at the top of the ram body, and the main shaft is located at the bottom of the ram body. The gearbox and the main shaft are connected by a coupling. However, with this structure, the coupling is relatively long, resulting in a large distance between the power output and the main shaft, leading to significant torque loss. Therefore, a preferred approach is to use a drive assembly comprising a drive motor and a gearbox 42 connected between the drive motor 41 and the main shaft. The top plate 13 is connected to one end of the first upright plate 11, the second upright plate 12, the third upright plate, and the fourth upright plate. The bottom plate is connected to the second upright plate 12, the third upright plate, and the fourth upright plate. The main shaft 3 is mounted on the bottom plate, and the drive assembly is located inside the ram body 1 and positioned between the bottom plate and the first upright plate 11. With this structure, the gearbox is directly connected to the main shaft, avoiding the need for a coupling. The distance from the power output to the main shaft is short, resulting in less torque loss, and it also allows users to easily add a center water outlet configuration.

[0023] A strip-fitting mechanism 7 is provided between the hydrostatic guide rail 33 and the slide block 2. Similarly, there are various ways to implement the strip-fitting mechanism, such as using existing structures. For ease of adjustment of the strip-fitting structure, preferably, as shown below... Figure 3 As shown, the insert mechanism includes an insert 71, a first baffle 72 fixed to one end of the insert 71, and a locking structure for locking the first baffle 72 onto the slide block 2; the locking structure includes a first screw 751 for connecting the first baffle 72 and the slide block 2 and a second screw 752 connected to the first baffle 72 for abutting against the slide block 2.

[0024] Using the above-mentioned insert mechanism, the first baffle is locked onto the slide 2 by the first screw, and then tightened by the second screw to achieve compaction. The entire adjustment process can be carried out only on the side where the first baffle is outside the groove, which is convenient for adjustment.

[0025] The back-and-forth movement of the slide along the guide rail will cause wear on the insert. In order to facilitate the adjustment of the distance between the insert and the slide and extend the service life of the insert, the first baffle 72 is provided with a waist-shaped hole, and the first screw 751 is set in the waist-shaped hole. The adjustment direction of the waist-shaped hole is perpendicular to the insert 71.

[0026] To reduce the impact of foreign objects, a scraper 76 is fixed on the first baffle 72, and the scraping part of the scraper 76 is placed on the same plane as one side of the first baffle 72.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
