Description

Technical Field

[0001] This utility model belongs to the field of metal heat treatment technology, and specifically relates to a drive wheel quenching device. Background Technology

[0002] As a core component of mechanical transmission systems, drive wheels are widely used in engineering machinery, agricultural machinery, transportation equipment, and other fields. Their working environments are often harsh, requiring them to withstand significant loads, friction, and impact forces. Therefore, extremely high requirements are placed on their mechanical properties, such as hardness, wear resistance, and fatigue strength. Quenching is a key process for improving the mechanical properties of drive wheels. By heating the drive wheel to above its critical temperature and then rapidly cooling it, its surface hardness and internal strength can be significantly improved, thereby extending its service life.

[0003] Traditional devices have poor adaptability to different specifications of drive wheels, and the clamping mechanism is complicated to adjust. It often requires the replacement of multiple parts to fix drive wheels of different sizes. The cooling method of traditional devices is singular, and the contact between the cooling medium and the drive wheel is uneven. In addition, the rotational stability of the worktable is insufficient, which can easily cause defects such as quenching cracks and deformation, affecting product quality. Therefore, a drive wheel quenching device has emerged. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a drive wheel quenching device, comprising:

[0027] The lifting and cooling mechanism 100 includes a cooling pool 101, a guide shaft 102 fixedly installed on the side of the cooling pool 101, a connecting horizontal plate 103 slidably connected to the surface of the guide shaft 102, a cylinder mounting plate 104 fixedly installed on the top of the guide shaft 102, a cylinder 105 disposed on the surface of the cylinder mounting plate 104, a longitudinal connecting plate 106 fixedly installed on the side wall of the connecting horizontal plate 103, and a rotary table mounting plate 107 fixedly installed on the side wall of the longitudinal connecting plate 106.

[0028] The heating and rotation drive mechanism 200 includes a support column 201 fixedly installed on the side of the cooling pool 101, a fixing block 202 fixedly installed on the side wall of the support column 201, a slider 203 slidably connected to the side wall of the T-shaped groove on the surface of the support column 201, a lead screw 204 that is threaded and engages with the threaded hole of the slider 203 and whose end rotates on the fixing block 202, a heating coil 205 movably installed on the side wall of the slider 203, a rotary table assembly 206 movably installed on the surface of the rotary table mounting plate 107, and a fastening assembly 207 movably installed on the surface of the rotary table assembly 206.

[0029] In the lifting and cooling mechanism 100, the cooling pool 101 is used to hold the quenching coolant, providing a cooling medium for the quenching process. A cylinder mounting plate 104 is fixedly installed on the top of the guide shaft 102. A cylinder 105 is disposed on the surface of the cylinder mounting plate 104, and its extension shaft passes through a through hole on the surface of the cylinder mounting plate 104 and is connected to the connecting horizontal plate 103. A longitudinal connecting plate 106 is fixedly installed on the side wall of the connecting horizontal plate 103, and a rotary table mounting plate 107 is fixedly installed on the side wall of the longitudinal connecting plate 106. When the cylinder 105 extends or retracts, it can drive the connecting horizontal plate 103, the longitudinal connecting plate 106, and the rotary table mounting plate 107 to rise and fall together along the guide shaft 102. In the heating and rotation drive mechanism 200, the support column 201 is fixedly installed on the side of the cooling pool 101, and a fixing block 202 is fixedly installed on its side wall. The surface of the support column 201 is provided with a T-shaped groove, and the slider 203 is slidably connected to the side wall of the T-shaped groove. The lead screw 204 engages with the threaded hole of the slider 203 via a thread, and its end rotates within the fixed block 202. Rotating the lead screw 204 causes the slider 203 to move up and down along the T-shaped groove of the support column 201. The heating coil 205 is movably mounted on the side wall of the slider 203, and its relative position to the drive wheel can be adjusted as the slider 203 moves.

[0030] Specifically, the rotary table assembly 206 includes an independent bearing mounting plate 206a movably mounted on the surface of the rotary table mounting plate 107, an independent bearing 206b fixedly mounted on the surface of the independent bearing mounting plate 206a, a flange 206c fixedly mounted on the top of the independent bearing 206b, a motor 206d movably mounted on the surface of the rotary table mounting plate 107 and located in the hollow space inside the inner wall of the independent bearing 206b, and a rotary disk 206e movably mounted on the surface of the flange 206c.

[0031] Furthermore, the independent bearing mounting plate 206a is movably mounted on the surface of the rotary table mounting plate 107, providing a mounting base for the entire rotary table assembly. The independent bearing 206b is fixedly mounted on the surface of the independent bearing mounting plate 206a, serving to support the bearing and reduce rotational friction. The flange 206c is fixedly mounted on top of the independent bearing 206b, used to connect the independent bearing 206b and the rotary disk 206e. The motor 206d is movably mounted on the surface of the rotary table mounting plate 107, located in the hollow space inside the independent bearing 206b. The output shaft of the motor 206d is connected to the rotary disk 206e, providing power for the rotation of the rotary disk 206e. The rotary disk 206e is movably mounted on the surface of the flange 206c, and driven by the motor 206d, it can rotate around the axis of the independent bearing 206b, thereby driving the drive wheel placed on it to rotate together, allowing for uniform heating and cooling of all parts of the drive wheel.

[0032] Preferably, the fastening assembly 207 includes a fastening assembly mounting plate 207a movably mounted on the surface of the rotating disk 206e, a sleeve 207b fixedly mounted on the surface of the fastening assembly mounting plate 207a, a threaded rod 207c that rotates by thread engagement with the sleeve 207b, a sliding ring 207d that engages by thread engagement with the surface of the threaded rod 207c, a mounting ring 207e fixedly mounted on the side wall of the sliding ring 207d, a fixing lug 207f fixedly mounted on the side wall of the mounting ring 207e, a connecting rod 207g rotatably connected to the end of the fixing lug 207f by a pin, and a support plate 207h rotatably connected to the end of the connecting rod 207g by a pin.

[0033] It should be noted that the fastening assembly mounting plate 207a is movably mounted on the surface of the rotating disk 206e, providing a mounting carrier for the entire fastening assembly. The sleeve 207b is fixedly mounted on the surface of the fastening assembly mounting plate 207a. The threaded rod 207c rotates within the sleeve 207b via a threaded engagement. The sliding ring 207d rotates within the threaded rod 207c via a threaded engagement. The sliding ring 207d moves up and down on the surface of the threaded rod 207c as the threaded rod 207c rotates. The mounting ring 207e is fixedly mounted on the side wall of the sliding ring 207d and moves with it. The fixing lug 207f is fixedly mounted on the side wall of the mounting ring 207e. The connecting rod 207g is rotatably connected to the end of the fixing lug 207f via a pin, and the support plate 207h is rotatably connected to the end of the connecting rod 207g via a pin. When the sliding ring 207d moves up and down, it will cause the support plate 207h to open or close through the mounting ring 207e, the fixing ear 207f and the connecting rod 207g, thereby pressing against or loosening the side wall of the drive wheel through hole, thus achieving the fastening or loosening of the drive wheel.

[0034] In use, operate the cylinder 105 in the lifting and cooling mechanism 100 to retract the extension shaft of the cylinder 105, causing the connecting horizontal plate 103, the longitudinal connecting plate 106, and the rotary table mounting plate 107 to descend along the guide shaft 102, adjusting the rotary table assembly 206 to a suitable clamping height. Place the drive wheel to be quenched on the surface of the rotary disk 206e of the rotary table assembly 206, aligning the through hole of the drive wheel with the fastening assembly 207. Operate the fastening assembly 207, rotating the threaded rod 207c, causing the sliding ring 207d to move upward on the surface of the threaded rod 207c. Through the mounting ring 207e, the fixing ear 207f, and the connecting rod 207g, the support plate 207h opens, pressing against the side wall of the drive wheel through hole, firmly clamping the drive wheel on the rotary disk 206e. Manually rotate the wheel at one end of the lead screw 204, driving the lead screw 204 to rotate, causing the slider 203 to move along the T-axis of the support column 201. The sliding groove moves up and down, thereby adjusting the position of the heating coil 205 to maintain a suitable heating distance from the drive wheel. The motor 206d in the rotary table assembly 206 is started, and the motor 206d drives the rotary disk 206e to rotate around the axis of the independent bearing 206b, which in turn drives the drive wheel to rotate together. The heating coil 205 is then turned on to heat the rotating drive wheel.

[0035] In summary, the T-shaped groove of the support column 201 and the T-shaped protrusion of the slider 203 are in clearance fit, and the lead screw 204 and the slider 203 are in thread fit, which makes the position adjustment of the heating coil 205 precise and stable, avoiding deviation during the adjustment process and ensuring the accuracy of the heating position. When clamping the drive wheel, the threaded rod 207c and the sliding ring 207d of the fastening assembly 207 can quickly and firmly clamp drive wheels of different sizes. The operation is simple and efficient, and it can adapt to the quenching requirements of various specifications of drive wheels. In the rotary worktable assembly 206, the motor 206d drives the rotary disk 206e to rotate stably, so that the drive wheel is heated and cooled evenly during the heating and cooling process, avoiding local overheating or insufficient cooling, improving the quenching quality of the drive wheel, and enhancing its hardness, wear resistance and fatigue strength.
