Description

Technical Field

[0001] This application relates to the field of tool support technology, and in particular to a cross rail system for tool feeding. Background Technology

[0002] In industrial manufacturing, machining, and various precision operations, such as power tools, gasoline-powered tools, and hydraulic power tools, the positioning and feed accuracy is crucial to product quality.

[0003] Because cutting and grooving machines have power ratings above 3KW and saw blade diameters between 350 and 600mm, the total working weight of the machine reaches 10-20KG. Handheld cutting is not feasible for extended periods of precise cutting, and the work area is either a vertical wall or horizontal space, posing safety risks. A guide rail is needed for support and manual or motorized feeding. However, in existing technologies, some guide rail structures only allow feed movement in one direction and lack a transmission system; the guide rail merely provides support. Other guide rail structures also only allow feed movement in one direction, and although they have a transmission system, this system is not interlocked, preventing arbitrary stopping positions. If the drive unit stops inputting power, the tool will scrape off the cutting surface, causing a safety accident. Therefore, the purpose of this application is to solve one or more of the above problems.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

The second driving device is used to drive the sliding of the second sliding unit, and the support interface is used to connect the tool.

[0010] In some embodiments, the mounting bracket has an L-shaped profile, and the secondary guide rail is perpendicular to the primary guide rail via the mounting bracket.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0025] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a cross rail system for tool feeding, mainly comprising: a main guide rail 1, with fixing plates 11 at both ends of the main guide rail 1 to install the main guide rail 1 in a preset position; a first sliding unit 2, slidably disposed on the main guide rail 1, with a first driving device 21 and a mounting bracket 22 mounted on the first sliding unit 2, the first driving device 21 being used to drive the sliding of the first sliding unit 2, and a secondary guide rail 3 fixedly disposed on the mounting bracket 22; and a second sliding unit 4, slidably disposed on the secondary guide rail 3, with a second driving device 41 and a support interface 42 mounted on the second sliding unit 4, the second driving device 41 being used to drive the sliding of the second sliding unit 4, and the support interface 42 being used to connect a tool.

[0026] Specifically, the first sliding unit 2 can slide on the main guide rail 1 to control the longitudinal movement of the tool mounted on the support interface 42, and the second sliding unit 4 slides on the secondary guide rail 3 to control the lateral movement of the tool. The combination of the first sliding unit 2 and the second sliding unit 4 enables the tool to achieve precise feeding in any direction.

[0027] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0028] Preferably, the mounting bracket 22 has an L-shaped profile, and the secondary guide rail 3 is perpendicular to the main guide rail 1 through the mounting bracket 22. In this configuration, the main and secondary guide rails 3 are perpendicular to each other in a cross shape, allowing the support interface 42 to move arbitrarily on a plane.

[0029] Reference Figure 2As shown, the first driving device 21 includes a first reduction gearbox 211 and a first driving gear 212. A driving part 5 is provided on the input shaft of the first reduction gearbox 211, and the first driving gear 212 is connected to the output shaft of the first reduction gearbox 211. A main rack 12 is fixedly provided on the main guide rail 1. The first driving gear 212 and the main rack 12 mesh with each other. With this arrangement, when the driving part 5 drives the first sliding unit 2 to move, the sliding speed of the first sliding unit 2 becomes more controllable under the action of the first reduction gearbox 211.

[0030] Specifically, the first reduction gearbox 211 includes a worm gear 2111 and a worm 2112. The worm 2112 is connected to the drive unit 5. The worm gear 2111 is coaxial with the first drive gear 212. According to the characteristics of the worm gear 2111 and the worm 2112, when the worm 2112 rotates, the worm 2112 can drive the worm gear 2111 and thus affect the first drive gear 212. However, when the worm gear 2111 rotates, the worm 2112 is not affected. This allows the worm 2112 to lock the worm gear 2111 when the first sliding unit 2 stops at any point on the main guide rail 1, preventing the first sliding unit 2 from falling under the action of gravity and affecting the movement accuracy of the main guide rail 1.

[0031] 5. The cross guide rail system for tool feeding according to claim 4, characterized in that the second driving device 41 includes a second reduction gearbox 411 and a second driving gear 412, a driving part 5 is provided on the input shaft of the second reduction gearbox 411, the second driving gear 412 is connected to the output shaft of the second reduction gearbox 411, a secondary rack 31 is fixedly provided on the secondary guide rail 3, and the second driving gear 412 and the secondary rack 31 mesh with each other. This arrangement makes the sliding speed of the first sliding unit 2 more controllable under the action of the second reduction gearbox 411 when the driving part 5 drives the second sliding unit 4 to move.

[0032] As can be seen, the internal structure of the second gearbox 411 is consistent with the internal structure and function of the first gearbox 211.

[0033] Reference Figure 3-4 As shown, in order to enable users to select the appropriate driving method according to different usage scenarios, the driving unit 5 adopts either a manual crank 51 or a motor 52.

[0034] Specifically, the first sliding unit 2 and the second sliding unit 4 are respectively provided with a first conical guide wheel 23 and a second conical guide wheel 43. The main guide rail 1 and the secondary guide rail 3 have grooves on both sides that cooperate with the first conical guide wheel 23 and the second conical guide wheel 43. This arrangement of the first conical guide wheel 23 and the second conical guide wheel 43 can effectively help the first sliding unit 2 and the second sliding unit 4 slide, and also play a certain role in preventing the first sliding unit 2 and the second sliding unit 4 from disengaging from the main guide rail 1 and the secondary guide rail 3.
