Description

Technical Field

[0001] The invention belongs to the technical field of machinery and relates to a sliding block. Background Art

[0002] Sliders are commonly used mechanical parts and are widely used in various types of mechanical equipment. Flange-type slides are used in conjunction with slide rails, and whether their structure is reasonable has an important impact on the entire sliding pair. To this end, people have conducted long-term explorations and proposed various solutions. However, although the existing technology has improved the structure of flange-type slides to a certain extent, it still has technical problems such as complex structure and difficulty in processing and manufacturing.

[0003] For example, a flange-type slider disclosed in a Chinese patent document (application number: 201720279100.1) includes a body, two connectors 1 and 2 are symmetrically arranged on the lower side of the body, a guide groove is formed between connector 1 and connector 2, steel ball grooves are arranged at the upper and lower ends of the inner sides of connector 1 and connector 2, and an adjustment block capable of adjusting the height relative to the body is arranged horizontally on the lower side of the body, and the adjustment block is located between connector 1 and connector 2. When the flange-type slider moves on the guide rail, there is no locking mechanism arranged at any position between the slider and the guide rail, so the slider cannot be locked on the guide rail, which reduces the accuracy of movement. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the prior art and to provide a slider with a locking function and a reliable and stable structure.

[0005] The objective of the present invention can be achieved through the following technical solutions: a slider, comprising a main body, the lower end of the main body having connecting parts on both sides, characterized in that a locking block and a driving member that drives the locking block to extend out of the inner side wall of the connecting part are provided on the inner side of the connecting part, a pushing block is fixedly connected to the output end of the driving member, the inner end face of the locking block has an inclined surface one, the outer end face of the pushing block has an inclined surface two and the inclined surface one abuts against the inclined surface two.

[0006] A row of toothed portions are provided on the side of the guide rail, and the outer end of the locking block matches the saw teeth. When the slider moves to the set position, the driving member drives the pushing block to move and pushes the locking block to extend out of the inner side wall of the connecting portion, and drives the locking block to float left and right through the inclined surface one and the inclined surface two, so that the outer end of the locking block is embedded in the groove of the corresponding toothed portion, so that the slider and the guide rail are locked. The slider is locked with the guide rail at any position, which has the advantages of simple structure and reliable locking.

[0007] In the above-mentioned slider, the middle part of the connecting part has an installation cavity, two parallel limit plates are arranged in the installation cavity, the locking block is located between the two limit plates and the two side walls of the locking block are respectively against the inner side walls of the limit plates, and springs are arranged between the outer side walls of the two limit plates and the connecting part. The spring pushes the limit plate so that the locking block can move left and right, which has the advantages of simple structure and reliable operation.

[0008] In the above-mentioned slider, the outer side wall of the limit plate is provided with a positioning convex body and one end of the spring is sleeved on the positioning convex body. One end of the spring is sleeved on the positioning convex body, which has a better positioning effect on the spring.

[0009] In the above-mentioned sliding block, a tension spring is provided between the pushing block and the locking block. By providing the tension spring, the locking block has a tendency to reset, so that the tension spring can drive the locking block to separate from the toothed portion of the guide rail.

[0010] In the above-mentioned slider, the driving member includes a hydraulic cylinder whose cylinder body is horizontally fixedly connected to the connecting part, and the piston rod of the hydraulic cylinder is fixedly connected to the pushing block. The hydraulic cylinder drives the pushing block to move, which has the advantages of large thrust and good locking effect.

[0011] In the above-mentioned sliding block, the driving member is an electric cylinder arranged on the connecting portion, and the output end of the electric cylinder is fixedly connected to the pushing block.

[0012] In the above-mentioned slider, the outer end of the locking block is a locking portion with a sharp angle, and the outer end of the locking portion is a rounded transition. With the above-mentioned arrangement, the locking block can smoothly enter the toothed portion of the guide rail, which has the advantage of smooth operation.

[0013] In the above-mentioned slider, the outer end of the locking part is axially fixed with a roller. By providing the above-mentioned roller, the roller can roll relative to the toothed part of the guide rail, so that the locking part can be inserted into the toothed groove of the toothed part of the guide rail.

[0014] In the above-mentioned sliding block, the outer end of the locking block has two locking parts. The above-mentioned arrangement has the advantage of good locking effect.

[0015] In the above-mentioned slider, the outer end of the limit plate is provided with a bent blocking portion and the blocking portion can block the installation cavity. The above-mentioned arrangement has a simple structure and a good effect of blocking the installation cavity, thereby increasing the service life.

[0016] Compared with the prior art, this slider has the following advantages:

[0017] 1. The hydraulic cylinder drives the push block to move and pushes the locking block to extend out of the inner side wall of the connecting part, and drives the locking block to float left and right through the inclined surface 1 and the inclined surface 2, so that the outer end of the locking block is embedded in the groove of the corresponding tooth-shaped part, so that the slider and the guide rail are locked. The slider is locked with the guide rail at any position, which has the advantages of simple structure and reliable locking;

[0018] 2. The locking block can move left and right by pushing the limit plate through the spring, which has the advantages of simple structure and reliable operation;

[0019] 3. A tension spring is provided between the push block and the locking block, so that the locking block has a tendency to reset, making it easier for the tension spring to drive the locking block to separate from the toothed portion of the guide rail.

[0020] 4. The outer end of the locking block is a pointed locking portion, and the outer end of the locking portion is a rounded transition, so that the locking block can smoothly enter the toothed portion of the guide rail, which has the advantage of smooth operation.
