Description

Technical Field

[0001] The invention relates to the technical field of tooling fixtures, and in particular to a fine grinding tool for improving the verticality of a cylindrical helical compression spring. Background Art

[0002] During the current cylindrical spring production process, after winding, cutting, and heat treatment, the spring's end faces must be fine-ground to ensure perpendicularity. Existing methods typically involve an operator holding the spring against a grinding wheel. This method results in significant deviations in the perpendicularity of the spring's end faces, failing to meet operational requirements and resulting in a low pass rate. Summary of the Invention

[0003] The present invention provides a fine grinding tool for improving the verticality of a cylindrical helical compression spring, which solves the problem of large verticality deviation and low pass rate of the cylindrical spring end face in the prior art.

[0004] The technical solution of the present invention is achieved as follows: A fine grinding tool for improving the verticality of a cylindrical helical compression spring comprises a tool base and a spring platform. The tool base is arranged on a grinding wheel protective plate. The spring platform is slidably connected to the tool base. A V-shaped groove is provided on the spring platform for limiting the verticality of the cylindrical spring. Both side surfaces of the V-shaped groove are perpendicular to the end face of the grinding wheel. An operator places the cylindrical spring to be processed in the V-shaped groove. The V-shaped groove plays a positioning role for the cylindrical spring, pushing the cylindrical spring close to the grinding wheel for fine grinding, thereby ensuring the verticality of the end face of the cylindrical spring.

[0005] The spring platform is provided with at least two parallel V-grooves for limiting cylindrical springs of different diameters. V-grooves of different sizes are suitable for cylindrical springs of different diameters, thereby improving the applicability of the fine grinding tooling.

[0006] The tool base is fixed to the grinding wheel guard plate by bolts and nuts. The bolts pass through the tool base and the grinding wheel guard plate in sequence and are connected with the nut threads. The bolt and nut connection structure is simple and convenient for installing the tool base of the fine grinding tool.

[0007] The tool base is provided with a longitudinal chute, and a slider is provided at the bottom of the spring platform. The chute and the slider are slidably connected, allowing the spring platform to slide back and forth on the tool base. Adjusting the position of the V-groove relative to the end face of the grinding wheel ensures more uniform grinding wheel consumption during fine grinding, thereby increasing the lifespan of the grinding wheel. Screws are provided on the side walls of the tool base, and the side walls of the tool base are threadedly connected to the screws. The screws pass through the side walls of the tool base and correspond to the slider. When the fine grinding tool is in use, the slider is moved to a designated position, and the screws are tightened to fix the slider's relative position within the chute, facilitating the use of the fine grinding tool.

[0008] The beneficial effects of the present invention are as follows: the fine grinding tooling has a simple structure and is easy to manufacture, and the fine grinding tooling is fixed to the grinding wheel protection plate by bolts and nuts, the connection method is simple, and the installation of the fine grinding tooling is convenient, the spring platform can slide back and forth to change the relative position of the V-groove and the end face of the grinding wheel, so that the grinding wheel is consumed evenly and the service life of the grinding wheel is increased, and V-grooves of different sizes correspond to cylindrical springs of different diameters, so that the fine grinding tooling has strong applicability.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0016] Example 1, as Figure 1 、 Figure 2As shown, a fine grinding tool for improving the verticality of a cylindrical helical compression spring includes a tool base 8 and a spring platform 9. The tool base 8 is arranged on a grinding wheel guard plate 1. The tool base 8 is detachably connected to the grinding wheel guard plate 1. The spring platform 9 is slidably matched with the tool base 8. The spring platform 9 can slide back and forth on the tool base 8. A V-groove 91 is provided on the spring platform 9 for limiting the verticality of the cylindrical spring. The V-groove 91 positions the outer circle of the cylindrical spring so that the cylindrical spring can only move axially in the V-groove. The spring platform 9 that slides back and forth can change the relative position of the V-groove 91 and the end face of the grinding wheel 4. Both side surfaces of the V-groove 91 are perpendicular to the end face of the grinding wheel 4, ensuring that the cylindrical spring is perpendicular to the end face of the grinding wheel 4, and ensuring the verticality of the end face of the cylindrical spring after fine grinding.

[0017] Further, if Figure 3 As shown, the spring platform 9 is provided with at least two parallel V-grooves 91 for limiting cylindrical springs of different diameters. In this embodiment, the number of the V-grooves 91 is 3, and the sizes of the various V-grooves 91 are not equal. V-grooves 91 of different sizes are suitable for cylindrical springs of different diameters, thereby improving the applicability of the fine grinding fixture.

[0018] Further, if Figure 2 As shown, the tool base 8 is fixed to the grinding wheel guard plate 1 via bolts 2 and nuts 5. Bolts 2 pass through the tool base 8 and the grinding wheel guard plate 1, threadedly engaging the nuts 5. A spring washer 6 and a flat washer 7 are positioned between the nuts 5 and the grinding wheel guard plate 1. These washers work together to prevent the nuts 5 from loosening and disperse pressure, further stabilizing the connection between the bolts 2 and nut 5. Furthermore, the simple connection between the bolts 2 and nut 5 facilitates installation and removal of the fine grinding tool.

[0019] Further, if Figure 2 、 Figure 4 As shown, the fixture base 8 is provided with a longitudinal slide groove, and a slider 92 is provided at the lower portion of the spring platform 9. The slide groove and the slider 92 are slidably connected. The slider 92 can slide back and forth within the slide groove, and the slider 92 drives the spring platform 9 to slide back and forth, thereby changing the relative position of the spring platform 9 and the end face of the grinding wheel 4. The side wall of the fixture base 8 is provided with a screw 3, and the side wall of the fixture base 8 is threadedly connected to the screw 3. The screw 3 passes through the side wall of the fixture base 8 and corresponds to the slider 92. When the spring platform 9 is moved to the designated working position, the screw 3 is tightened to fix the spring platform 9, ensuring the stability of the fine grinding tool during use.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
