Description

Technical Field

[0001] The utility model relates to the technical field of gear ring production, in particular to a quenching tool used for gear ring production. Background Art

[0002] Ring gear is a mechanical engineering term that generally refers to a circular mechanical device with teeth, which is mainly used to transmit rotational power through meshing.

[0003] In the prior art, the ring gear is a common part in the machinery industry. It is used for the transmission and drive of mechanical equipment in work and production. In order to enhance its surface hardness, wear resistance and impact resistance, thereby improving the overall performance and service life of the ring gear, it is usually necessary to quench the ring gear.

[0004] However, the existing electromagnetic quenching equipment for gear rings requires the use of a fixture to install the gear ring on a machine tool, and an electromagnetic coil to locate the center of the gear ring for electromagnetic heating. However, the fixture of the existing gear ring machine tool is relatively simple and cannot adapt to gear rings with different inner ring sizes. At the same time, the electromagnetic coil is prone to skew when locating the gear ring, resulting in poor quenching and heating effect. Utility Model Content

[0005] The purpose of the present utility model is to provide a quenching tool for gear ring production to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a quenching tool for gear ring production, the quenching tool for gear ring production comprising:

[0012] Preferably, a driving shaft is fixed on the surface of the top block, and the transmission plate is movably sleeved on the driving shaft and the outer surface of the transmission shaft.

[0013] Preferably, a positioning block is fixed on the inner side of the top block, and the positioning block corresponds to the positioning groove and is movably locked.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Due to the thread fit, the rotation of the screw will drive the thread ring to rotate and move along the axis of the screw. The rotation of the transmission plate will change the angle between it and the drive shaft. The transmission plate will support the top block to move along the positioning groove, and multiple groups of top blocks are driven by a group of screws, so multiple groups of top blocks will support the gear ring at the same time to fix the gear ring in the quenching chamber. This clamping method can be adjusted by rotating the screw, so it can be used to clamp and fix gear rings of different sizes. Moreover, multiple groups of top blocks move at the same time and distance, so the center of the gear ring can be found to prevent the gear ring from being skewed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1 to 6 The utility model provides a technical solution: a quenching tool for gear ring production, wherein an induction coil 3 and a support block 7 are fixed to the inner wall of the quenching chamber 1, a support plate 9 is fixed to the end of the support block 7, a screw 2 is movably inserted into the support plate 9, a motor 8 is fixed to the end of the screw 2, and the motor 8 is started to drive the screw 2 to rotate. Due to the thread matching, the rotation of the screw 2 will drive the threaded ring 4 to rotate and move along the axis direction of the screw 2.

[0025] A driving ring 10 is fixed at the end, and a transmission plate 5 is movably provided on the outer surface of the driving ring 10. A top block 6 is movably provided at the end of the transmission plate 5. The movement of the driving ring 10 will support the transmission plate 5 to rotate around the transmission shaft 21. The rotation of the transmission plate 5 will change the angle between it and the driving shaft 16, and the transmission plate 5 will support the top block 6 to move along the positioning groove 15.

[0026] On the basis of the first embodiment, in order to achieve the adjustability of the clamp, a positioning groove 15 is provided on the side surface of the support block 7 , a through hole 14 is provided on the surface of the support plate 9 , and an annular groove 13 is provided on the inner wall of the through hole 14 .

[0027] An annular block 12 is fixed on the outer surface of the screw 2. The annular block 12 corresponds to and is clamped in the annular groove 13, forming a movably connected connection. On the one hand, it enables a movably connected connection between the screw 2 and the support plate 9. On the other hand, it serves as a limit for the screw 2 to prevent the screw 2 from deviating when rotating. The motor 8 is located below the support plate 9.

[0028] The threaded ring 4 is sleeved on the outer surface of the screw 2, and a transmission shaft 11 is fixed to the outer surface of the drive ring 10. The movement of the threaded ring 4 will drive the drive ring 10 to move. The movement of the drive ring 10 will push the transmission plate 5 to rotate around the transmission shaft 21. The rotation of the transmission plate 5 will change the angle between it and the drive shaft 16. The transmission plate 5 will push the top block 6 to move along the positioning groove 15.

[0029] A driving shaft 16 is fixed on the surface of the top block 6, and the transmission plate 5 is movably sleeved on the outer surface of the driving shaft 16 and the transmission shaft 11. The movement of the driving ring 10 will support the transmission plate 5 to rotate around the transmission shaft 21. The rotation of the transmission plate 5 will change the angle between it and the driving shaft 16, thereby playing a transmission role.

[0030] A positioning block 17 is fixed on the inner side of the top block 6. The positioning block 17 corresponds to the positioning groove 15 and is movably clamped. On the one hand, it enables a movably connection between the top block 6 and the support block 7. On the other hand, it limits the top block 6 to prevent the top block 6 from moving and deviating on the support block 7.

[0031] The specific solution is as follows: when the gear ring needs to be installed for quenching, the motor 8 is started to drive the screw 2 to rotate. Due to the threaded fit, the rotation of the screw 2 will drive the threaded ring 4 to rotate and move along the axis of the screw 2. The movement of the threaded ring 4 will drive the drive ring 10 to move. The movement of the drive ring 10 will support the transmission plate 5 to rotate around the transmission shaft 21. The rotation of the transmission plate 5 will change the angle between it and the drive shaft 16. The transmission plate 5 will support the top block 6 to move along the positioning groove 15, and multiple groups of top blocks 6 are driven by a group of screws 2, so multiple groups of top blocks 6 will simultaneously support the gear ring to fix the gear ring in the quenching chamber 1. This clamping method can be adjusted by rotating the screw 2, so it can be used for clamping and fixing gear rings of different sizes, and multiple groups of top blocks 6 move at the same time and distance, so the center of the gear ring can be found to prevent the gear ring from being skewed.

[0032] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
