Description

Technical Field

[0001] This utility model relates to the field of combined diamond roller technology, specifically a combined diamond roller capable of grinding various groove spacings. Background Technology

[0002] Diamond rollers are mainly used in the dressing of grinding wheels on special machine tools for profile grinding and grinding machine processing. In traditional industries, when grinding is performed using grinding wheels, the abrasive grains of the grinding wheel gradually become rounded and blunt under the action of friction and extrusion. As a profile dressing tool roller, diamond rollers are gradually recognized by the market for their excellent characteristics of high hardness and long service life. They are now widely used.

[0003] Existing combined diamond rollers are mostly unable to grind various groove spacings and cannot adjust the distance between multiple sets of diamond rollers, thus reducing the applicability of combined diamond rollers; therefore, we need to propose a combined diamond roller that can grind various groove spacings. Utility Model Content

[0004] The purpose of this invention is to provide a combined diamond roller capable of grinding various groove spacings. Two sets of limiting frames are snapped onto the outer arc surface of the rotating shaft by a snap-fit ​​assembly, thereby fixing the diamond roller body through the two sets of limiting frames. The snap-fit ​​assembly drives the abutting arc plate away from the rotating shaft, and then adjusts the position of the diamond roller body to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined diamond roller capable of grinding various groove spacings, comprising a diamond roller body and a rotating shaft, wherein a fixed plate is fixedly connected to one end of the rotating shaft, and a clamping plate is threadedly connected to the other end of the rotating shaft, wherein the diamond roller body is provided in several groups, wherein each group of diamond roller bodies is sleeved on the outer arc surface of the rotating shaft, wherein limit frames are fixedly installed on both sides of each group of diamond roller bodies, and wherein each group of limit frames slides on the outer arc surface of the rotating shaft;

The eccentric post is eccentrically installed at both ends of the pressing post. The pressing post rotates eccentrically inside the limiting frame via the eccentric post. The limiting post is fixedly installed on the upper surface of the clamping arc plate. The clamping arc plate is moved inside the limiting frame via the eccentric post, and the clamping arc plate is located below the pressing post.

[0008] Preferably, the positioning module includes an operation plate and a spring plunger. The operation plate is fixedly installed on the outer arc surface of the pressing column, and the spring plunger is fixedly installed on both sides of the operation plate. The limiting frame has a swing groove corresponding to the operation plate and the spring plunger inside, and the inner wall of the swing groove has a plurality of positioning holes corresponding to the spring plunger.

[0009] Preferably, the limiting frame has a limiting groove inside that corresponds to the two sets of limiting posts, and the limiting posts are slidably disposed inside the limiting groove.

[0010] Preferably, the outer arc surface of the rotating shaft is provided with a snap-fit ​​arc groove corresponding to the abutting arc plate, and the abutting arc plate is slidably disposed inside the snap-fit ​​arc groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides: a combined diamond roller capable of grinding various groove spacings, such as... Figure 1-4 As shown, the device includes a diamond roller body 1 and a rotating shaft 5. One end of the rotating shaft 5 is fixedly connected to a fixed plate 4, and the other end of the rotating shaft 5 is threadedly connected to a clamping plate 7. The diamond roller body 1 is provided with several sets, and each set of diamond roller bodies 1 is sleeved on the outer arc surface of the rotating shaft 5. Limiting frames 2 are fixedly installed on both sides of each set of diamond roller bodies 1. Each set of limiting frames 2 slides on the outer arc surface of the rotating shaft 5. The limiting frames 2 are fixed to the rotating shaft 5 by a snap-fit ​​assembly, thereby fixing the position of the diamond roller body 1. Since the clamping arc plate 13 is inserted into the snap-fit ​​arc groove 6, it is ensured that the rotating shaft 5 can drive the diamond roller body 1 to rotate. By releasing the fixing of the limiting frames 2 to the rotating shaft 5 by the snap-fit ​​assembly, the diamond roller body 1 can be moved, thereby adjusting the spacing between the sets of diamond roller bodies 1, and thus improving the applicability of the combined diamond roller.

[0023] Preferably, several sets of limiting frames 2 are provided with snap-fit ​​components on their inner sides for convenient adjustment of the spacing between the diamond roller bodies 1. The snap-fit ​​components include pressing posts 12, abutting arc plates 13, eccentric posts 14, limiting posts 15, and positioning modules. The eccentric posts 14 are eccentrically installed at both ends of the pressing posts 12, and the pressing posts 12 rotate eccentrically inside the limiting frames 2 through the eccentric posts 14. The limiting posts 15 are fixedly installed on the upper surface of the abutting arc plates 13, and the abutting arc plates 13 are movable inside the limiting frames 2 through the eccentric posts 14, with the abutting arc plates 13 located below the pressing posts 12. The positioning module includes an operation plate 3 and a spring plunger 18. The operation plate 3 is fixedly installed on the outer arc surface of the pressing post 12, and the spring plunger 18 is fixedly installed on both sides of the operation plate 3. The limiting frame 2 has swing grooves corresponding to the operation plate 3 and the spring plunger 18 inside. Several sets of positioning holes 19 corresponding to the spring plunger 18 are formed on the inner wall of the swing grooves. The outer arc surface of the rotating shaft 5 has a snap-fit ​​arc groove 6 corresponding to the pressing arc plate 13. The pressing arc plate 13 is slidably disposed inside the snap-fit ​​arc groove 6. The operation plate 3 swings the pressing post 12 to rotate eccentrically. After the connecting post 12 rotates, the distance between it and the pressing arc plate 13 changes continuously. When the operating plate 3 rotates to one end, the pressing post 12 contacts the pressing arc plate 13, and the pressing arc plate 13 moves closer to the locking arc groove 6. Thus, the pressing arc plate 13 presses against the inside of the locking arc groove 6, thereby fixing the displacement of the limiting frame 2 and the rotating shaft 5, thereby fixing the position of the diamond roller body 1 and the rotating shaft 5. At this time, the spring plunger 18 is inserted into the positioning hole 19 to fix the position of the operating plate 3, preventing the operating plate 3 from rotating when the rotating shaft 5 rotates.

[0024] Furthermore, the limiting frame 2 has a limiting groove 17 corresponding to the two sets of limiting posts 15 inside, and the limiting posts 15 are slidably disposed inside the limiting groove 17. The limiting posts 15 limit the pressing arc plate 13 to prevent the pressing arc plate 13 from moving out of the limiting frame 2. The limiting groove 17 ensures that the limiting posts 15 can move up and down. Thus, when the rotating pressing post 12 moves away from the pressing arc plate 13, the pressing arc plate 13 will not press against the inside of the snap-fit ​​arc groove 6, thereby facilitating the adjustment of the position of the diamond roller body 1.

[0025] It is worth noting that a threaded rod 10 is threaded through the side of the clamping disc 7. A clamping pad 9 is fixedly connected to one end of the threaded rod 10 near the fixed disc 4. The clamping pad 9 contacts a set of limiting frames 2. When the diamond roller body 1 at the end away from the fixed disc 4 is fixed, rotating the threaded rod 10 causes the clamping pad 9 to contact the limiting frame 2 on the side of the diamond roller body 1 away from the fixed disc 4, thereby providing auxiliary fixation for the diamond roller body 1 and preventing the diamond roller body 1 from rotating away from the rotating shaft 5 and causing injury to personnel.

[0026] Specifically, an operating column 8 is fixedly installed on the side of the clamping plate 7 away from the fixed plate 4, and a bolting column 11 is fixedly installed on the side of the clamping plate 7 close to the fixed plate 4. The end of the rotating shaft 5 away from the fixed plate 4 is provided with a threaded hole 16 corresponding to the bolting column 11. The operating column 8 is provided to facilitate the rotation and movement of the clamping plate 7, and the bolting column 11 is threaded into the threaded hole 16, thereby fixing the position of the rotating shaft 5 and the clamping plate 7.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
