Description

Technical Field

[0001] This utility model belongs to the field of machine tool slide technology, and specifically relates to a slide with good wear resistance. Background Technology

[0002] Machine tools are machines used to manufacture machines, also known as machine tools or machine tools. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. They are parts with high precision requirements and fine surface roughness requirements. They generally need to be finally processed by cutting methods on machine tools. Machine tools play an important role in the modernization of the national economy.

[0003] Machine tools have many parts, and the slide, as a part of the machine tool, plays an important role. The existing slide design has a simple structure and poor wear resistance. The slide wears a lot during use, which affects the service life of the slide and obviously can no longer meet people's needs. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a slide with good wear resistance, which can increase wear resistance and is easy to replace.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a slide block with good wear resistance, including a slide block body, a lead screw hole on the slide block body, a wear-resistant component sleeved inside the lead screw hole, the wear-resistant component including a wear-resistant sleeve, a plurality of balls rotatably disposed inside the side wall of the wear-resistant sleeve, the balls protruding from the inner wall of the wear-resistant sleeve, an oil passage connecting the chambers of the plurality of balls inside the wear-resistant sleeve, and an oil injection hole communicating with the oil passage in the wear-resistant sleeve.

[0006] The wear-resistant sleeve is equipped with a limiting ring.

[0007] The outer wall of the wear-resistant sleeve is provided with an anti-slip sleeve.

[0008] The interior of the slide body is hollowed out to form a cavity, and multiple reinforcing plates are installed inside the cavity, with the multiple reinforcing plates being interconnected.

[0009] The reinforcing plate has through holes.

[0010] The inner corner of the through hole is set with an arc-shaped chamfer.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a wear-resistant slide block. The wear resistance is increased by adding a wear-resistant sleeve inside the lead screw hole. The wear-resistant sleeve contains ball bearings, which enhance the rotational stability of the lead screw. Lubricating oil can be periodically injected into the ball bearing chambers through the oil injection hole and transmitted through the oil circuit to the chambers of multiple balls. This increases both wear resistance and rotational stability. When replacement is needed, the wear-resistant sleeve can be simply pulled out, thus achieving both increased wear resistance and easy replacement. Attached Figure Description

[0013] The markings in the diagram are: 1. Slide body; 2. Wear-resistant sleeve; 3. Ball bearing; 4. Oil passage; 5. Oil injection hole; 6. Limiting ring; 7. Anti-slip sleeve; 8. Reinforcing plate; 9. Through hole; 10. Curved chamfer. Detailed Implementation

[0014] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0015] like Figs. 1-3 As shown, this embodiment provides a wear-resistant slide block, including a slide block body 1. The slide block body 1 has a lead screw hole, and a wear-resistant component is sleeved inside the lead screw hole. The wear-resistant component includes a wear-resistant sleeve 2. Multiple balls 3 are rotatably arranged inside the side wall of the wear-resistant sleeve 2. The balls 3 protrude from the inner wall of the wear-resistant sleeve 2. The wear-resistant sleeve 2 has an oil passage 4 that connects the chambers of the multiple balls 3. The wear-resistant sleeve 2 has an oil injection hole 5 that communicates with the oil passage 4. Specifically, the wear-resistant sleeve 2 is made of wear-resistant alloy, and a limiting ring 6 is provided on the wear-resistant sleeve 2. Wear resistance is increased by adding a wear-resistant sleeve 2 inside the lead screw hole. The wear-resistant sleeve 2 contains ball bearings 3, which enhances the rotational stability of the lead screw. Lubricating oil can be periodically injected into the cavity of the ball bearings 3 through the oil injection hole 5 and transmitted through the oil passage 4 to the cavities of multiple ball bearings 3. This increases both wear resistance and rotational stability. When replacement is needed, the wear-resistant sleeve 2 can be clamped and pulled out directly using clamping pliers, thus increasing wear resistance and facilitating replacement.

[0016] Furthermore, the outer wall of the wear-resistant sleeve 2 is provided with an anti-slip sleeve 7. The anti-slip sleeve 7 ensures that the wear-resistant sleeve 2 is stably fitted to the lead screw hole.

[0017] Furthermore, the interior of the slide body 1 is hollowed out to form a cavity, and multiple reinforcing plates 8 are installed inside the cavity, with the multiple reinforcing plates 8 interconnected. The hollowed-out design reduces the weight of the slide body 1, and the multiple reinforcing plates 8 enhance the strength of the slide body 1.

[0018] Furthermore, the reinforcing plate 8 is provided with a through hole 9. Specifically, the inner corner of the through hole 9 is provided with an arc-shaped chamfer 10. The provision of the through hole 9 further reduces the weight of the slide body 1, and the arc-shaped chamfer 10 makes the transition of the inner corner of the through hole 9 smooth.

[0019] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
