Description

Technical Field

[0001] This utility model relates to the field of tool magazine drive technology, specifically a novel drive mechanism for tool magazines. Background Technology

[0002] Tool magazine drive mechanisms are mechanical or electric devices used in machine tools or automated equipment to control the storage, retrieval, handling, and replacement of tools. These drive mechanisms enable the tools in the tool magazine to be automatically or semi-automatically retrieved, installed, and positioned through various means (such as electric, pneumatic, and hydraulic), thereby improving machining efficiency and accuracy.

[0003] In the existing technology, the connection and use of the tool magazine is inconvenient, which can easily lead to unstable transmission effect and affect the normal use of the device;

[0004] To overcome the above shortcomings, a Chinese patent (publication number CN212977574U) discloses a drive mechanism for a tool magazine of a CNC engraving machine, which can prevent interference with the dustproof cloth during compression and is also waterproof. It includes a gantry bracket, one side of which is connected to a concealed bracket. A fixedly connected drive mechanism is embedded inside the concealed bracket. The drive mechanism includes a drive motor and a reducer connected to the drive motor. A cylindrical connecting cover is fitted onto the outside of the concealed bracket. The output end of the drive mechanism is fixedly connected to the bottom of the connecting cover. The mounting hole of the tool magazine mechanism is fitted onto the outside of the concealed bracket and fixedly connected to the top of the connecting cover.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, traditional tool magazine drive mechanisms use spur gear transmission mechanisms, which have poor positioning accuracy and are prone to large errors during transmission. Utility Model Content

[0006] The purpose of this utility model is to provide a novel drive mechanism for tool magazines, in order to solve the problem mentioned in the background art that the traditional drive mechanism for tool magazines uses a spur gear transmission mechanism, which has poor positioning accuracy and is prone to large errors during transmission.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel drive mechanism for a tool magazine, comprising a housing and a servo motor disposed inside the housing;

[0008] The output end of the servo motor is fixedly mounted with a first helical gear, and the lower end of the first helical gear is meshed with a second helical gear, and the acute angle between the first helical gear and the second helical gear is blunted.

[0009] A transmission rack is provided on the inner side of the left end of the housing, and the surface of the transmission rack meshes with the lower end of the second helical gear.

[0010] Furthermore, an oil storage tank is fixedly installed at the upper end of the housing, and an automatic lubrication mechanism is provided inside the oil storage tank. The automatic lubrication mechanism is equipped with a rotating rod, and the rear end of the rotating rod is rotatably mounted on the housing.

[0011] Furthermore, a transmission belt is fitted onto the surface of the rotating rod via a pulley, and the lower end of the transmission belt is positioned at the output end of the servo motor via a pulley.

[0012] Furthermore, the front end of the rotating rod is provided with a reciprocating threaded section, and a movable plate is threadedly installed on the surface of the reciprocating threaded section. The movable plate is Z-shaped, and a limit rod is installed through the outer side of the movable plate. The rear end of the limit rod is fixedly installed on the housing.

[0013] Furthermore, the upper end of the oil storage tank is provided with a feeding port, and a filter screen is nested inside the oil storage tank. A partition is fixedly installed on the inner wall of the oil storage tank, and a drainage port is provided at the outer end of the partition.

[0014] Furthermore, a sealing plate is installed through the outer end of the oil storage tank, and the outer end of the sealing plate is fixedly installed at the rear end of the movable plate, with the upper end of the sealing plate fitting against the lower end of the partition.

[0015] Furthermore, a connecting pipe is installed through the lower end of the oil storage tank, and an oil inlet is connected to the outside of the connecting pipe. The lower end of the oil inlet is fixedly installed on the surface of the shell, and the output end of the oil inlet is aligned with the meshing point of the first helical gear and the second helical gear.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Inside the housing, a servo motor drives a first helical gear for transmission. The rotation of the first helical gear drives a second helical gear that meshes with it for transmission. With the help of a transmission rack, the acute angle between the first and second helical gears is blunted to assist in transmission. In use, the traditional spur gear transmission mechanism is replaced with a helical gear transmission mechanism plus a servo motor, which improves the positioning accuracy of the transmission, reduces the transmission error, and enables more stable transmission.

[0018] 2. Before using this new type of tool magazine drive mechanism, add lubricating oil to the oil storage tank through the feeding port. After being filtered by the filter screen, the lubricating oil can enter the oil inlet through the connecting pipe. The oil inlet setting can accurately add lubricating oil to the connection between the first helical gear and the second helical gear, which can improve the lubrication effect of the device, prevent the device from wearing out after a long period of use, which would lead to the loss of drive transmission power, and ensure the stable operation of the device.

[0019] Furthermore, during servo motor transmission, the rotating rod is driven to rotate via a transmission belt. When the rotating rod rotates, the reciprocating threaded area on its surface can achieve indirect lubrication through a threadedly connected moving plate, which helps save resources. At the same time, it can automatically add lubricating oil during operation, eliminating the need for manual lubrication and reducing the workload for staff. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figures 1-4The technical solution shown is a novel drive mechanism for a tool magazine. In order to solve the problem of low transmission accuracy of traditional drive mechanisms, the following is disclosed: a housing 1 and a servo motor 2 installed inside the housing 1. A first helical gear 3 is fixedly installed at the output end of the servo motor 2, and a second helical gear 4 is meshed at the lower end of the first helical gear 3. The acute angle between the first helical gear 3 and the second helical gear 4 is blunted. A transmission rack 5 is provided on the inner side of the left end of the housing 1, and the surface of the transmission rack 5 meshes with the lower end of the second helical gear 4.

[0029] In use, the traditional spur gear transmission mechanism is replaced with a helical gear transmission mechanism plus a servo motor 2, which improves the positioning accuracy of the transmission, reduces the transmission error, and enables more stable transmission. Therefore, inside the housing 1, the servo motor 2 drives the first helical gear 3 for transmission. The rotation of the first helical gear 3 can drive the second helical gear 4 that meshes with it for transmission. With the setting of the transmission rack 5, the acute angle between the first helical gear 3 and the second helical gear 4 is blunted to assist in the transmission.

[0030] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of easy damage to the transmission power of the mechanism after prolonged use: an oil reservoir 12 is fixedly installed at the upper end of the housing 1, and an automatic lubrication mechanism is provided inside the oil reservoir 12. The automatic lubrication mechanism includes a rotating rod 7, with its rear end rotatably mounted on the housing 1. A transmission belt 6 is sleeved on the surface of the rotating rod 7 via a pulley, and the lower end of the transmission belt 6 is located at the output end of the servo motor 2 via a pulley. A reciprocating threaded section 8 is provided at the front end of the rotating rod 7, and a movable plate 9 is threaded onto the surface of the reciprocating threaded section 8. The movable plate 9 is Z-shaped, and a limit rod 10 is installed through the outer side of the movable plate 9. The rear end of 10 is fixedly installed on the housing 1. The upper end of the oil storage tank 12 is provided with a feeding port 13. The oil storage tank 12 is nested with a filter screen plate 14. The inner wall of the oil storage tank 12 is fixedly installed with a partition plate 15. The outer end of the partition plate 15 is provided with a drainage port 16. The outer end of the oil storage tank 12 is connected with a sealing plate 11. The outer end of the sealing plate 11 is fixedly installed on the rear end of the moving plate 9. The upper end of the sealing plate 11 is attached to the lower end of the partition plate 15. The lower end of the oil storage tank 12 is connected with a connecting pipe 17. The outer side of the connecting pipe 17 is connected to an oil inlet 18. The lower end of the oil inlet 18 is fixedly installed on the surface of the housing 1. The output end of the oil inlet 18 is aligned with the meshing point of the first helical gear 3 and the second helical gear 4.

[0031] Before using this new type of tool magazine drive mechanism, lubricating oil is added to the oil storage tank 12 through the feeding port 13. After being filtered by the filter screen 14, the lubricating oil can enter the oil inlet 18 through the connecting pipe 17. The oil inlet 18 can accurately add lubricating oil to the connection between the first helical gear 3 and the second helical gear 4, which can improve the lubrication effect of the device and prevent the device from wearing out after a long period of use, thus reducing the power consumption of the drive and ensuring the stable operation of the device. At the same time, when the servo motor 2 is driven, the rotating rod 7 is driven to rotate through the transmission belt 6. When the rotating rod 7 rotates, the reciprocating threaded section 8 on its surface can move back and forth through the threaded moving plate 9 under the limit of the limiting rod 10. The movement of the moving plate 9 can make the sealing plate 11 move back and forth to open or close the unblocking port 16 on the partition 15, which can achieve the effect of indirect oil supply, which can save resources and can also automatically add lubricating oil during operation, eliminating the need for manual lubrication by the staff and reducing the tediousness of the work.

[0032] 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.
