Description

Technical Field

[0001] The utility model relates to the field of slotting machines, in particular to a novel transmission mechanism of a slotting machine. Background Art

[0002] The gantry slotting machine is a flat slotting machine. A gantry bracket is set up above the fixed platform, and the slotting knife is driven to slot on the object by driving the gantry bracket. The existing gantry bracket connects the slide rail with the slide rail in the vertical direction, and then drives it through the gear rack transmission perpendicular to the slide rail. The slide rail and the rack act on different support plates. After long-term use, the distance between the slide rail and the rack will increase, causing the rack gear to slip or separate, greatly reducing its transmission efficiency. In addition, the gantry slotting machine has high speed requirements during the sliding process. If it is too slow, it will affect the slotting effect. If it is too fast, there will be a "flying car" phenomenon, which affects the processing efficiency and makes it difficult to adjust its sliding speed. Utility Model Content

[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and the drawings of the description.

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a novel transmission mechanism for a slotting machine, which has the advantages of preventing the gear rack from disengaging and making the transmission more stable.

[0005] The utility model provides a novel transmission mechanism of a slotting machine, which is arranged at one side of the slotting machine, and comprises a slide rail, a gear condition, a slide seat, a gear assembly and a speed control assembly. The slide rail is connected to the side wall of the slotting machine, the slide seat is slidably connected to the slide rail, the gear condition is arranged below the slide rail, the gear assembly is arranged on the slide seat and meshes with the gear condition, the speed control assembly is arranged between the slide seat and the slotting machine, and the speed control assembly increases the resistance of the slide seat to the operation.

[0006] In some embodiments, the speed control assembly includes a limit plate arranged below the tooth condition and a stop groove arranged on the slide seat, a plurality of accommodating cavities are arranged in parallel on one side of the limit plate, a slider is arranged in the accommodating cavity, a protrusion is arranged on the side wall of the slider, the portion of the slider below the protrusion extends from the bottom of the accommodating cavity, the slider can movably enter the stop groove, rollers are arranged on the front and rear sides of the stop groove, and the slider moves up and down under the action of the rollers.

[0007] In some embodiments, the side of the slider close to the retaining groove is V-shaped, the outer wall ring of the roller is provided with a convex strip, and the side of the slider close to the retaining groove is provided with a groove that can engage with the convex strip.

[0008] In some embodiments, a balancing hole is provided on the top of the accommodating cavity.

[0009] In some embodiments, a side wall of the slotting machine is provided with a chip guard plate, and the chip guard plate cover is arranged above the slide rail.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are:

[0011] 1. The utility model arranges the slide rail above the gear condition so that the two are fixed on the same plane, thereby effectively avoiding the resonance noise caused by the elastic deformation of the frame generated when the gear and the gear condition are meshing with load, reducing the elastic deformation of the guide rail mounting surface, and effectively improving the groove planing accuracy of the groove planing machine; by setting a speed control component, the interaction between the roller and the slider controls the sliding of the slide within the target speed. When the slide seat runs too slowly, the slider cannot overcome the static friction of the roller rotation and cannot run. When the slide seat runs too fast, the horizontal impact of the roller is much greater than the friction between the roller and the slider along the tangential direction. At this time, the slider cannot rise under the action of the friction force and still cannot run, thereby realizing the control of the slide rail speed.

[0012] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0013] Undoubtedly, these and other objects of the present invention will become more apparent after the following detailed description of the preferred embodiments described with reference to various figures and drawings.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model, but not to limit the utility model. Example

[0036] Reference Figure 2The utility model provides a new transmission mechanism of a slotting machine, which is arranged on one side of the slotting machine, and includes a slide rail 1, a gear condition 2, a slide seat 3 and a gear assembly 4. The slide rail 1 is connected to the side wall of the slotting machine, the slide seat 3 is slidably connected to the slide rail 1, the gear condition 2 is arranged below the slide rail 1, and the gear assembly 4 is arranged on the slide seat 3 and meshes with the gear condition 2. The side wall of the slotting machine is provided with a chip guard plate 6, and the chip guard plate 6 cover is arranged above the slide rail 1. If necessary, the hollow plate position is hollowed out on the gantry of the slotting machine to reduce the mass of the gantry, reduce the overall weight of the square box, and thus reduce the inertia generated when the square box is running, so as to achieve the purpose of rapid response to start and stop. Example

[0037] Reference Figure 1 and 3 The difference between this embodiment and embodiment 1 is that the transmission mechanism in this embodiment further includes a speed control component 5. The speed control component 5 is arranged between the slide 3 and the slotting machine, and the speed control component 5 is used to increase the resistance of the slide 3. Specifically: Figure 4 The speed control assembly 5 includes a limit plate 51 disposed below the gear condition 2 and a stop groove 52 disposed on the slide 3. A plurality of accommodating cavities 51a are disposed in parallel on one side of the limit plate 51. A balancing hole 51c is disposed on the top of the accommodating cavity 51a. A slider 51b is disposed in the accommodating cavity 51a. A protrusion is disposed on the side wall of the slider 51b. The portion of the slider 51b below the protrusion extends from the bottom of the accommodating cavity 51a. The slider 51b can movably enter the stop groove 52. Rollers 52a are disposed on both the front and rear sides of the stop groove 52. The slider 51b moves up and down under the action of the rollers 52a. The side of the slider 51b close to the stop groove 52 is V-shaped. The outer wall of the roller 52a is provided with a convex strip. The side of the slider 51b close to the stop groove 52 is provided with a groove that can engage with the convex strip.

[0038] Working principle: The slide rail 1 fixes the slide 3 on the slotting machine platform, and drives the gear assembly 4 to rotate to move the gantry as a whole. When the speed is appropriate, when the roller 52a runs to the bottom of the corresponding slider 51b, it will rotate under the friction of the slider 51b, causing the slider 51b to retract, allowing the slide 3 to run at an appropriate speed.
