Abstract
Description
Technical Field
[0001] The utility model relates to a grooving device and a triangular belt grooving punching machine thereof. Background Art
[0002] V-belt grooving machine is a machine used to process V-belts (also called V-belts). V-belts are usually used to transmit power and have a triangular cross-section, which can provide better traction and transmission efficiency. V-belt grooving machine is used to cut the notch of V-belts for installation and use in mechanical systems.
[0003] After the existing V-belt grooving is completed, the length of the V-belt that needs to be cut is calculated according to the required matching gear specifications. Therefore, the above process requires the joint participation of the grooving machine and the cutting machine to produce a V-belt that meets the specifications.
[0004] The existing grooving machine needs to position the V-belt during the grooving process to prevent the V-belt from shifting during the grooving process and causing the notch to not meet the specifications. In order to solve the above problem, the existing technology usually uses a V-belt passing between two opposite rollers, and fixes one end of the V-belt on one side of the V-belt by CNC during grooving. The fixing of both ends reduces the grooving defects of the notch, which is inconvenient and has a high testing cost. Utility Model Content

DETAILED DESCRIPTION
[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0020] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] like Figure 1 , Figure 2 As shown, a V-belt grooving and punching machine comprises a frame 1. A reel 2 for reeling a rubber sheet is arranged on one side of the frame 1. A plurality of guide mechanisms 3 for guiding the moving direction of the rubber sheet are arranged on one side of the reel 2, which is a prior art and will not be described in detail.
[0023] A grooving device 4 for grooving and positioning the rubber sheet and a cutting device 5 for cutting the rubber sheet to make it conform to the V-belt specifications used for small gears are arranged on one side of the guide mechanism 3 .
[0024] 1. Grooving device 4
[0025] like Figure 2 , Figure 3 As shown, the grooving device 4 includes a bracket 6 arranged on the frame 1 and fixedly connected to the frame 1. A cylinder 7 is arranged on the top of the bracket 6. A toothed cutter 8 for grooving is connected to the bottom of the cylinder 7. A plurality of cutting teeth 9 are arranged on the toothed cutter 8 for cutting a tooth shape on the surface of the rubber sheet, and a pressure rod 10 is arranged on one side of the toothed cutter 8. A clamping member 11 is arranged at the bottom of the pressure rod 10. A clamping member 2 12 is arranged at the bottom of the clamping member 11.
[0026] The clamping member 11 and the clamping member 2 12 are slidably connected to a fixed seat 13. The clamping member 2 12 is fixedly arranged, and the clamping member 11 can slide in the groove arranged in the fixed seat 13. When the cylinder 7 drives the toothed cutter 8 to move downward, the surface of the rubber sheet below the toothed cutter 8 is cut into a tooth shape by the toothed cutter 8. At the same time, the pressure rod 10 drives the clamping member 11 to move downward and enables the clamping member 11 and the clamping member 2 12 to clamp the rubber sheet together, so that the rubber sheet can remain stable during cutting, and prevent the rubber sheet from shifting its position during cutting, causing the tooth shape to deform. The above-mentioned setting does not need to be controlled by numerical control technology, reduces the number of tests, and can achieve a better positioning and fixing effect of the cutting teeth 9.
[0027] 2. Cutting device 5
[0028] like Figure 3-Figure 5 As shown, the cutting device 5 includes a mounting plate 14 fixedly connected to the fixing seat 13. A positioning plate 15 is fixedly connected to the mounting plate 14 by bolts. A sliding groove 16 is provided on the positioning plate 15. A cutting piece 17 and a cutting piece 2 18 are provided in a T-shape in the sliding groove 16. The cutting piece 2 18 is fixedly connected to one side of the bottom of the positioning plate 15, and the cutting piece 17 can slide up and down on the positioning plate 15. Among them, a spring 19 is provided between the cutting piece 17 and the cutting piece 2 18. The spring 19 is used for resetting the cutting piece 17 after it moves down or up, and its initial state is that the cutting piece 17 and the cutting piece 2 18 cooperate with each other. As shown Figure 6 As shown, a cutter 20 is provided at the bottom of the cutting piece 17, and a matching groove 21 matching with the cutter 20 is provided on the cutting piece 2 18.
[0029] Correspondingly, a pull rope 22 is provided between the cutting member 17 and the clamping member 11 described in the above-mentioned slotting device 4. A pulley 23 is provided in the middle of the pull rope 22. The pulley 23 is connected to a rotating shaft 24. The rotating shaft 24 is fixedly connected to the mounting plate 14.
[0030] As mentioned above, when the clamping member 11 moves down and performs the grooving process, the cutting member 17 moves up under the action of the pull rope 22, and the spring 19 accumulates elastic potential energy. After the grooving is completed, the clamping member 11 moves up and conveys the rubber sheet forward through the guide mechanism 3. When the clamping member 11 moves up, the spring 19 drives the cutting member 17 to move down, so that the cutting member 17 is pressed down so that the cutter 20 at the bottom and the matching groove 21 of the cutting member 2 18 cooperate with each other to cut, thereby cutting a shorter V-belt on the rubber sheet. After the cutting is completed, the above steps are repeated so that the specifications of the V-belt cut each time are consistent and meet the V-belt specifications required for matching with small gears.
[0031] The above process integrates grooving and cutting, and the V-belts cut to the same specifications can be achieved without the need for complex CNC technology, thereby reducing defects and improving production efficiency.
[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
