Description

Technical Field

[0001] The utility model relates to the field of linear optical axes, in particular to a highly wear-resistant chromium-plated linear optical axis. Background Technique

[0002] As a key component in mechanical transmission and positioning systems, linear optical axes are widely used in various precision machinery and equipment. Their design purpose is to achieve smooth, accurate, and reliable linear motion. The Chinese authorized utility model patent (Publication No.: CN221482390U) discloses a wear-resistant optical axis. The optical axis bodies can be connected through insertion posts and insertion slots to extend the length of the optical axis bodies. The screws are arranged in the limit slots and connected to the threaded holes through the screws, so as to realize the fixation between the optical axis bodies. The fixation is firm and convenient for disassembly. When the optical axis bodies are not connected together, it is convenient to transport the optical axis bodies.

[0003] However, when the above device is in use, there are still some deficiencies: specifically, on some devices with a compact structure and limited space, when it is not necessary to splice two or more linear optical axes, the insertion rods on the sockets at one end of the optical axis body always protrude outwards. This not only increases the overall size of the device but also may interfere with the surrounding assembly structures, affecting the overall performance and stability of the device. Therefore, in view of the above situation, a highly wear-resistant chromium-plated linear optical axis is proposed. Summary of the Utility Model

[0004] In order to make up for the problem in the prior art that when it is not necessary to splice two or more linear optical axes, the insertion rods on the sockets at one end of the optical axis body always protrude outwards, which not only increases the overall size of the device but also may interfere with the surrounding assembly structures, the utility model proposes a highly wear-resistant chromium-plated linear optical axis.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a highly wear-resistant chromium-plated linear optical axis, including two optical axis bodies. One end of the optical axis body is provided with a groove, and the other end of the optical axis body has a socket.

[0006] An indicating block is arranged on the groove, and an indicating groove is arranged on the surface of the socket. When the two optical axis bodies are assembled, the indicating block cooperates with the indicating groove.

[0007] A T-shaped groove is arranged on the socket, and a plug rod is slidably matched with the T-shaped groove. A limit groove is arranged on the outer wall of the plug rod.

[0008] A circular groove is arranged on the socket, and a movable groove is arranged on the circular groove. The movable groove communicates with the T-shaped groove. A limiting member is rotatably connected to the circular groove. When one end of the plug rod passes through the T-shaped groove, the limiting member passes through the movable groove and then enters the T-shaped groove to cooperate with the limit groove.

[0009] Preferably, the groove is provided with an insertion hole, and a positioning hole is provided at one end of the outer wall of the optical axis body close to the groove, and the positioning hole communicates with the insertion hole.

[0010] Preferably, a threaded hole is provided on the outer wall of the insertion rod. When the insertion rod is inserted and matched with the insertion hole, a bolt is inserted into the positioning hole, and the bolt is inserted into the threaded hole for cooperation.

[0011] Preferably, the insertion socket is of a slope structure, and the groove is of a trapezoidal structure.

[0012] Preferably, when the insertion rod extends into the T-shaped groove, one end of the insertion rod contacts the inner wall of the T-shaped groove, and after the limiting member rotates into the T-shaped groove, it contacts the other end of the insertion rod.

[0013] Preferably, the limiting member includes a limiting rod, a hollow hole is provided on the limiting rod, and a rotating shaft is fitted with a clearance on the hollow hole, and the rotating shaft is fixed on the circular groove.

[0014] Preferably, the insertion rod includes a square column body, one end of the square column body has a cylinder, and the limiting groove is provided on the surface of the cylinder.

[0015] Preferably, the outer surface of the optical axis body has a wear-resistant layer for improving the wear resistance of the optical axis body.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Through the structural design of the T-shaped groove, circular groove, movable groove, limiting groove and limiting member, the insertion rod can be retracted into the T-shaped groove without splicing the optical axis body, avoiding the problem that the insertion rod always protrudes out in the traditional design, effectively avoiding potential interference with the surrounding assembly structure when splicing is not required, reducing assembly conflicts caused by improper design, improving the overall compatibility and stability of the equipment. At the same time, when splicing two optical axis bodies, it can play a limiting role on the extended insertion rod to ensure the normal insertion and matching of the insertion rod and the insertion hole;

[0018] 2. Through the structural design of the indicating block and indicating groove, when splicing is carried out, through the cooperation of the indicating block and indicating groove, it can be ensured that after the insertion rod is inserted into the insertion hole, the threaded hole on the insertion rod is coaxial with the positioning hole, thereby facilitating the subsequent assembly and positioning of the bolt, providing convenience for the installation of the staff.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] The following will further elaborate on this application with reference to Figure 1 —6,

[0029] The embodiments of this application disclose a highly wear-resistant chrome-plated linear optical axis. Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, A highly wear-resistant chrome-plated linear optical axis, including two optical axis bodies 1. One end of the optical axis body 1 is provided with a groove 2, and the other end of the optical axis body 1 has a socket 3.

[0030] An indicating block 201 is arranged on the groove 2, and an indicating groove 301 is formed on the surface of the socket 3. When the two optical axis bodies 1 are assembled, the indicating block 201 cooperates with the indicating groove 301.

[0031] Among them, the indicating block 201 is a block for indicating, and the indicating groove 301 is a groove for cooperating with the indicating block 201.

[0032] A T-shaped groove 302 is formed on the socket 3, and a plug rod 4 is slidably fitted on the T-shaped groove 302. A limiting groove 401 is formed on the outer wall of the plug rod 4.

[0033] A circular groove 303 is formed on the socket 3, and a movable groove 304 is formed on the circular groove 303. The movable groove 304 is communicated with the T-shaped groove 302. A limiting member 5 is rotatably connected to the circular groove 303. When one end of the plug rod 4 passes through the T-shaped groove 302, the limiting member 5 passes through the movable groove 304 and then enters the T-shaped groove 302 to cooperate with the limiting groove 401.

[0034] Among them, the limiting member 5 includes a limiting rod, and a hollow hole is formed on the limiting rod. A rotating shaft is fitted in the hollow hole with a clearance, and the rotating shaft is fixed on the circular groove 303.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , A jack 202 is formed on the groove 2, and a positioning hole 203 is formed on the outer wall of the optical axis body 1 near one end of the groove 2. The positioning hole 203 is communicated with the jack 202.

[0036] Among them, by arranging the jack 202 to be inserted and matched with the plug rod 4, the positioning hole 203 is used for installing a bolt.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 And Figure 6 , A threaded hole is formed on the outer wall of the plug rod 4. When the plug rod 4 is inserted and matched with the jack 202, a bolt is inserted into the positioning hole 203, and the bolt is inserted into the threaded hole for matching.

[0038] Among them, when the two optical axis bodies 1 are spliced and used, after the plug rod 4 is inserted into the jack 202, the bolt is inserted from the positioning hole 203, and then the bolt is rotated to make it enter the threaded hole, thereby realizing the positioning of the plug rod 4, that is, realizing the fixation of the two optical axis bodies 1.

[0039] Refer to Figure 1 、 Figure 2And Figure 4 , the socket 3 has a sloping structure, and the groove 2 has a trapezoidal structure.

[0040] Among them, when splicing and using the two optical axis bodies 1, the groove 2 cooperates with the socket 3.

[0041] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 And Figure 6 , when the plug rod 4 extends into the T-shaped groove 302, one end of the plug rod 4 contacts the inner wall of the T-shaped groove 302, and after the limiting member 5 rotates into the T-shaped groove 302, it contacts the other end of the plug rod 4.

[0042] Among them, after the plug rod 4 is slid into the T-shaped groove 302, the plug rod 4 can be limited by rotating the limiting member 5 to prevent the plug rod 4 from accidentally sliding out.

[0043] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 And Figure 6 , the plug rod 4 includes a square column body, one end of the square column body has a cylinder, and the limiting groove 401 is opened on the surface of the cylinder.

[0044] Among them, one end of the plug rod 4 is designed to be square, which can ensure that the position of the screw hole on its surface remains unchanged during the process of the plug rod 4 sliding in and out, thereby facilitating the cooperation with the positioning hole 203.

[0045] Referring to Figure 1 , Figure 2 , Figure 3 And Figure 4 , the outer surface of the optical axis body 1 has a wear-resistant layer for improving the wear resistance of the optical axis body 1.

[0046] Among them, the wear resistance of the optical axis body 1 is improved by setting the wear-resistant layer. The wear-resistant layer is a chromium plating layer, which is realized by the electroplating chromium process. Chromium ions are deposited on the outer wall of the linear optical axis by electricity to form a uniform chromium plating layer, which is a well-known technical means for those skilled in the art and will not be elaborated here.

[0047] Working principle: When splicing two optical axis bodies 1, the insertion rod 4 on one of the optical axis bodies 1 is slid out of the T-shaped groove 302. By rotating the limiting member 5, the limiting member 5 is engaged with the limiting groove 401, thereby limiting the insertion rod 4. The insertion rod 4 on the above-mentioned optical axis body 1 is inserted into the insertion hole 202 on the other optical axis body 1. During this process, the indicating block 201 is inserted and engaged with the indicating groove 301, so as to ensure that after the insertion rod 4 is inserted, the screw hole on the insertion rod 4 is coaxial with the positioning hole 203. Then, the bolt is inserted into the positioning hole 203, and the bolt is tightened with the help of a tool, so that the bolt is engaged with the screw hole to realize the positioning of the insertion rod 4, that is, the assembly of the two optical axis bodies 1 is completed.

[0048] When the optical axis body 1 is used alone, after the insertion rod 4 is slid into the T-shaped groove 302, the limiting member 5 is rotated and then enters the T-shaped groove 302 to block the insertion rod 4, preventing the insertion rod 4 from sliding out of the T-shaped groove 302.

[0049] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
