Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a cutting device for the outer surface of a rubber part. Background Technology

[0002] Rubber, as a unique high-molecular elastic material, has excellent flexibility, wear resistance, corrosion resistance, and good sealing performance. These properties make it widely used in many industries such as automobile manufacturing, aerospace, medical devices, and home appliances. In order to meet the precise assembly requirements, the outer surface must be precisely cut to meet the design requirements in order to fit specific mechanical structures or sealing cavities and ensure the effectiveness of rubber parts in actual use.

[0003] Related technology can be found in Chinese Patent No. CN214055409U, which discloses a rubber part cutting device, including a base, a belt drive element fixedly connected to the top left of the base, and a set of limiting walls fixedly connected to the front and rear sides of the top of the base. In this utility model, limiting walls are first installed on both sides of the belt drive element added to the top of the base. Hydraulic pipes are installed inside the limiting walls to transmit hydraulic oil pumped by a hydraulic pump inside the base. Push blocks are installed on the inner side of the limiting walls, and pistons and hydraulic rods in the hydraulic pipes push them, forming two sets of hydraulic devices to guide and limit rubber parts of different sizes, preventing deviation during cutting. A grooved wheel is mounted on the right end of the belt drive element, and the grooved wheel intermittently engages with a meshing block on the added rotating column, allowing the belt drive element to intermittently drive the workpiece while the cutting blade is cutting. The entire structure is driven by only one set of drive devices, saving the cost of additional drive devices.

[0004] Regarding the aforementioned technologies, rubber parts are elastic and compressible. During the cutting process, due to the cutting force, rubber parts are prone to deformation, resulting in deviations between the cutting dimensions and the design dimensions, thus affecting the cutting accuracy. Utility Model Content

[0005] To improve the cutting accuracy of rubber parts, this application provides a cutting device for the outer surface of rubber parts.

[0006] This application provides a cutting device for the outer surface of rubber parts, which adopts the following technical solution: A device for cutting the outer surface of a rubber part includes a frame, a cutting machine at the upper end of the frame for cutting the rubber part, and a cutting fixture for working with the cutting machine to cut the rubber part. The cutting fixture has a receiving groove inside for fixing the rubber part during cutting, and a cutting groove on the cutting fixture for working with the cutting machine to cut the rubber part.

[0007] By adopting the above technical solution, the cutting fixture is used in conjunction with the cutting machine to ensure that the rubber parts are cut accurately. The design of the receiving groove ensures that the rubber parts are firmly fixed during the cutting process, reducing the probability of displacement or deformation of the rubber parts during the cutting process, thereby improving the cutting accuracy.

[0008] Optionally, a positioning plate is provided on the frame, which is used to position the cutting tooling for the cutting stroke.

[0009] By adopting the above technical solution, the positioning plate controls the cutting stroke of the cutting fixture, which helps to improve the consistency and accuracy of cutting, thereby improving the cutting quality of rubber parts.

[0010] Optionally, the positioning plate is provided with a sliding groove, and the positioning plate is slidably connected to the frame along the length of the frame.

[0011] By adopting the above technical solution, the slide allows the positioning plate to slide along the length of the frame, thereby realizing the adjustment of the cutting fixture position and increasing the flexibility and adaptability of the equipment.

[0012] Optionally, the frame is equipped with a fixing element that passes through a slide groove to fix the relative sliding of the positioning plate and the frame.

[0013] By adopting the above technical solution, the fixing component passes through the sliding groove to fix the relative sliding between the positioning plate and the frame, so that the positioning plate is stably fixed on the frame while completing the cutting stroke positioning, reducing the decrease in cutting accuracy caused by the loosening of the positioning plate and improving the working stability of the cutting equipment.

[0014] Optionally, the grooves are located on both sides of the positioning plate, and the width of the grooves is adapted to the fixing parts, and the length extension direction of the grooves is perpendicular to the cutting stroke direction of the rubber parts.

[0015] By adopting the above technical solution, the slide groove is set on both sides of the positioning plate, which ensures a stable sliding connection between the positioning plate and the frame, improves the positional accuracy of the cutting fixture during the cutting process, and the width of the slide groove is adapted to the fixing parts, reducing the probability of the positioning plate loosening or shifting during the working process, thus ensuring the reliability of the cutting.

[0016] Optionally, the frame includes a base and a mounting bracket, the mounting bracket being fixed on the base and mounting the cutting machine, the cutting machine including a cutting blade, the cutting blade being located vertically above the cutting stroke of the cutting fixture.

The cutting depth of the cutting groove matches the cutting depth of the rubber part, ensuring the accuracy and consistency of the cutting.

[0020] Optionally, a cutting groove is formed along the length of the cutting fixture, the cutting groove extending through two opposite sides of the receiving groove.

[0021] By adopting the above technical solution, the rubber parts are cut completely during the cutting process, reducing the scrap rate caused by incomplete cutting and improving the cutting quality of the rubber parts.

[0022] Optionally, the mounting bracket has a vertical slot, a screw is fixed on the cutting machine, and a nut is provided on the screw. The screw passes through the vertical slot and is threadedly connected to the nut.

[0023] By adopting the above technical solution, the position of the screw can be adjusted to achieve vertical adjustment of the cutting machine, which improves the applicability and flexibility of the equipment. The cooperation between the screw and the nut ensures the stability of the cutting machine position, thereby improving the stability of the cutting equipment.

[0024] Optionally, the width of the receiving groove is equal to the width of the rubber part, the receiving depth of the receiving groove is equal to the thickness of the rubber part, and the cross-section of the receiving groove is the same as the cross-section of the rubber part.

The cross-section of the receiving groove is the same as the cross-section of the rubber part, so that the receiving groove fits the rubber part and improves the fixing effect of the receiving groove on the rubber part.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the receiving groove ensures that the rubber part is firmly fixed during the cutting process, reducing the probability of displacement or deformation of the rubber part during the cutting process, thereby improving the cutting accuracy; 2.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses an outer surface cutting device for rubber parts. Example

[0032] Reference Figure 1 A rubber part outer surface cutting device includes a frame 1, which includes a base 11 and a mounting frame 12. The mounting frame 12 is fixed on the base 11, improving the stability of the entire device. A cutting machine 2 is mounted on the mounting frame 12. A vertical groove 15 is formed on the mounting frame 12. A screw 14 is fixed on the cutting machine 2, and a nut 141 is provided on the screw 14. The screw 14 passes through the vertical groove 15 and is threadedly connected to the nut 141. Adjusting the position of the screw 14 allows for vertical adjustment of the cutting machine 2, improving the applicability and flexibility of the device. The threaded connection reduces the probability of movement of the cutting machine 2, improving cutting stability. The cutting device also includes a cutting fixture 25, which works in conjunction with the cutting machine 2 to ensure precise cutting of the rubber part 3, improving the accuracy of the device. The cutting machine 2 includes a cutting blade 22, which is located vertically above the cutting stroke of the cutting fixture 25, ensuring accurate cutting position and reducing cutting quality problems caused by positional deviation.

[0033] Reference Figure 1 The frame 1 is equipped with a positioning plate 13. During cutting, the positioning plate 13 limits the cutting fixture 25, thereby controlling the cutting stroke of the cutting fixture 25 and improving the consistency and accuracy of the cutting. The positioning plate 13 has a sliding groove 132, which slides along the length of the frame 1, thereby adjusting the position of the cutting fixture 25 and increasing the flexibility and adaptability of the equipment. The sliding groove 132 is located on both sides of the positioning plate 13 and extends along the width of the positioning plate 13, ensuring a stable sliding connection between the positioning plate 13 and the frame 1 and improving the positional accuracy of the cutting fixture 25 during the cutting process.

[0034] Reference Figure 1The frame 1 is provided with a fixing member 131. The fixing member 131 passes through the slide groove 132 to fix the relative sliding of the positioning plate 13 and the frame 1, thereby positioning the positioning plate 13 and making the positioning plate 13 stably fixed on the frame 1. The width of the slide groove 132 is adapted to the fixing member 131, which reduces the decrease in cutting accuracy caused by the loosening of the positioning plate 13 and improves the working stability of the cutting equipment.

[0035] Reference Figure 1 and Figure 2 The cutting fixture 25 has a receiving groove 24. When cutting the rubber part 3, the rubber part 3 is placed in the receiving groove 24. The width of the receiving groove 24 is equal to the width of the rubber part 3, which reduces the probability of the rubber part 3 moving laterally during cutting, thereby improving the cutting accuracy. The receiving depth of the receiving groove 24 is equal to the thickness of the rubber part 3. The receiving groove 24 cooperates with the cutting blade 22 to reduce the displacement of the rubber part 3 in the vertical direction, further improving the cutting accuracy. The cross-section of the receiving groove 24 is the same as the cross-section of the rubber part 3, so that the receiving groove 24 fits the rubber part 3, improving the fixing effect of the receiving groove 24 on the rubber part 3.

[0036] Reference Figure 2 A cutting groove 23 is formed along the length of the cutting fixture 25. The cutting groove 23 works in conjunction with the cutting blade 22. The cutting groove 23 penetrates the two opposite sides of the receiving groove 24, improving the cutting quality of the rubber part 3. The width of the cutting groove 23 is greater than the thickness of the cutting blade 22, reducing the probability of jamming caused by the small gap between the cutting blade 22 and the cutting groove 23, and improving the smoothness of the cutting process. The cutting depth of the cutting groove 23 matches the cutting depth of the rubber part 3, improving the consistency of cutting the rubber part 3. The cutting depth of the cutting groove 23 is less than or equal to the receiving depth of the receiving groove 24, reducing the occurrence of overcutting or shallow cutting during the cutting process and improving the cutting accuracy of the equipment.

[0037] The implementation principle of the outer side cutting device for rubber parts in this application embodiment is as follows: The rubber part 3 is placed in the receiving groove 24 of the cutting fixture 25, and the receiving groove 24 fixes the rubber part 3. The position of the adjusting screw 14 is adjusted to realize the adjustment of the position of the cutting machine 2, thereby improving the flexibility of the cutting device. The position of the positioning plate 13 is adjusted, and the fixing part 131 fixes the positioning plate 13. The positioning plate 13 limits the cutting fixture 25, so that the cutting fixture 25 moves accurately under the cutting blade 22. The cutting blade 22 rotates to cut the rubber part 3. The receiving groove 24 reduces the probability of displacement of the rubber part 3 during cutting and improves the cutting accuracy.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
