Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, specifically a semi-enclosed linear guide for machine tools. Background Technology

[0002] A semi-enclosed linear guide is a mechanical component used in linear reciprocating motion applications. It is also known as a linear guide, slide rail, linear guide, or linear slide rail. It is mainly used to support and guide moving parts so that they can perform high-precision linear motion in a given direction. Linear guides can bear high rated loads and withstand a certain amount of torque, which makes them suitable for high-precision linear motion under high load conditions.

[0003] Existing semi-enclosed machine tool linear guides mostly use screw left and right drive components to control the movement of moving parts. However, during the use of semi-enclosed machine tool linear guides inside the machine tool, a large amount of particulate dust and other impurities are generated. These particulate dust particles enter the screw, increasing the wear between the screw and the moving parts. Prolonged use will cause wear between the moving parts and the screw, affecting the service life of the guide. Utility Model Content

[0004] The purpose of this invention is to provide a semi-enclosed linear guide for machine tools to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-enclosed machine tool linear guide rail, including a base, a screw installed in the middle of the base, a movable seat movably installed inside the base, the screw threadedly connected to the movable seat, sleeves symmetrically installed at both ends of the movable seat, the screw located inside the sleeves, an installation assembly installed between the sleeves and the movable seat, an air inlet pipe fixedly installed on the outer side of the sleeves, an air chamber opened inside the sleeves, the air inlet pipe communicating with the interior of the sleeves, and air outlet holes arranged in a ring array around the central axis of the sleeves on the inner ring of the sleeves.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a semi-enclosed machine tool linear guide includes a base 1, a screw 2 installed in the middle of the base 1, a movable seat 3 movably installed inside the base 1, the screw 2 being threadedly connected to the movable seat 3, sleeves 4 symmetrically installed at both ends of the movable seat 3, the screw 2 being disposed inside the sleeves 4, an installation assembly 5 installed between the sleeves 4 and the movable seat 3, an air inlet pipe 6 fixedly installed on the outer side of the sleeves 4, the air inlet pipe 6 being connected to the air outlet pipe of a blower, an air chamber 7 being formed inside the sleeves 4, and the air inlet pipe 6 being connected to the interior of the sleeves 4. The inner ring of sleeve 4 is provided with air outlets 8 arranged in a ring array around the central axis of sleeve 4. When assembling sleeve 4 and moving base 3, the sleeve 4 and moving base 3 can be installed by the operation of the installation component 5, which facilitates the installation of sleeve 4. When moving moving base 3, the operation of the blower sends air into the air chamber 7 inside sleeve 4 through the air inlet pipe 6 and blows air out from the air outlets 8. This can blow away particles, dust and other impurities on screw 2, prevent particles, dust and other impurities from entering the connection between screw 2 and moving base 3, prevent wear between screw 2 and moving base 3, and improve the service life of the device.

[0022] like Figures 1 to 4 As shown, a cover plate 9 is fixedly installed at one end of the sleeve 4, and the sleeve 4 and the cover plate 9 can be fixedly connected by means of sealant, bolts or the like.

[0023] After the air chamber 7 and air outlet 8 on the sleeve 4 are processed, the cover plate 9 can be fixed on the sleeve 4 to seal the end of the sleeve 4.

[0024] like Figures 1 to 4 As shown, the air outlet 8 is inclined toward one end near the cover plate 9.

[0025] The screw 2, which is located on the path of the sleeve 4, can blow particles, dust and other impurities on the outside of the sleeve 4 to prevent particles, dust and other impurities from re-entering the inside of the sleeve 4.

[0026] like Figures 1 to 4As shown, the installation assembly 5 includes a slot 10, a limiting rod 11, a locking block 12, a connecting cylinder 13, and a spring 14. The sleeve 4 has a slot 10 symmetrically opened at one end. The two ends of the movable seat 3 are symmetrically fixedly installed with limiting rods 11. The locking block 12 is slidably installed between the two limiting rods 11. The connecting cylinder 13 is symmetrically fixedly installed on the outer side of the locking block 12. The connecting cylinder 13 is slidably connected to the limiting rod 11. The outer side of one end of the limiting rod 11 is fitted with a spring 14. One end of the spring 14 is fixedly connected to the movable seat 3, and the other end of the spring 14 is fixedly connected to one end of the connecting cylinder 13.

[0027] Insert the sleeve 4 into the middle of both ends of the movable base 3. The spring 14 pushes the connecting cylinder 13, which can drive the locking block 12 to slide into the slot 10 to fix the position of the sleeve 4.

[0028] like Figures 1 to 4 As shown, an installation rod 15 is fixedly installed between the two connecting cylinders 13.

[0029] Pull the mounting rod 15 to slide the locking block 12 connected to the mounting rod 15 out of the slot 10, and the sleeve 4 and the movable seat 3 can be removed.

[0030] like Figures 1 to 4 As shown, the sleeve 4 has a chamfer 16 at the end corresponding to the slot 10.

[0031] This makes it easy to insert the card block 12 stably into the card slot 10.

[0032] like Figures 1 to 4 As shown, slide rails 17 are symmetrically fixedly installed inside the base 1, and the movable seat 3 is slidably installed between the two slide rails 17. A motor 18 is fixedly installed inside one end of the base 1, and the output end of the motor 18 is fixedly connected to one end of the screw 2.

[0033] The screw 2 is driven to rotate by the motor 18, and the screw 2 is connected to the movable seat 3 by a thread, which will cause the movable seat 3 to move along the track of the slide rail 17.

[0034] This utility model provides a semi-enclosed linear guide for machine tools, the specific working principle of which is as follows:

[0035] When assembling the sleeve 4 and the movable base 3, the sleeve 4 is inserted into the middle of both ends of the movable base 3. The spring 14 pushes the connecting cylinder 13, causing the locking block 12 to slide into the slot 10, thus fixing the position of the sleeve 4. To remove the sleeve 4, the mounting rod 15 is pulled, causing the locking block 12 connected to the mounting rod 15 to slide out of the slot 10, thus disassembling the sleeve 4 from the movable base 3. The motor 18 drives the screw 2 to rotate, and the screw 2 connects to the movable base... The threaded connection of 3 will drive the movable seat 3 to move along the track of the slide rail 17, which is used to move the components above the movable seat 3. During the movement of the movable seat 3, the operation of the blower will drive the air into the air chamber 7 inside the sleeve 4 through the air inlet pipe 6 and blow the air out from the air outlet 8. This can blow away the particles, dust and other impurities on the screw 2, prevent particles, dust and other impurities from entering the connection position between the screw 2 and the movable seat 3, prevent wear between the screw 2 and the movable seat 3, and improve the service life of the device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
