Description

Technical Field

[0001] The utility model relates to the technical field of bearing manufacturing, in particular to a special machine for fully automatic high-frequency induction heat treatment of the spherical surface of a spherical joint bearing. Background Art

[0002] Spherical spherical bearings typically require a hardened layer of a certain depth on the outer sphere, maintaining high hardness and wear resistance, while the remaining surface must maintain good toughness to accommodate the complex operating conditions of the spherical spherical bearing. Based on the structural and performance requirements of spherical spherical bearings, a process typically employs overall tempering heat treatment followed by high-frequency induction heat treatment of the outer sphere. However, in actual production, the heat treatment process for spherical spherical bearings typically involves manual loading and unloading, which is labor-intensive and inefficient. Furthermore, the heat treatment does not achieve a relatively ideal heat treatment effect. Therefore, it is necessary to develop a dedicated, fully automatic high-frequency induction heat treatment machine for spherical spherical bearing surfaces. Utility Model Content

[0019] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0020] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0021] like Figure 1As shown, this embodiment provides a special machine for fully automatic high-frequency induction heat treatment of the spherical surface of a joint bearing, which is used for heat treatment of the spherical surface of a joint bearing, including an automatic material sorting mechanism 10, a feeding and conveying component 20, a loading robot 30, a unloading robot 40, a heating and quenching component 50, a rotary table 60, a discharge and conveying component 70, and a storage bin 80. The rotary table 60 includes at least a loading position, a heating and quenching position, and an unloading position. The rotary table 60 is used to rotate and convey parts to different workstations. A positioning fixture for the joint bearing is provided on the rotary table 60. The discharge port of the automatic material sorting mechanism 10 is connected to the feeding and conveying component 20, and the feeding and conveying component 20 conveys the parts from the discharge port of the automatic material sorting mechanism 10 to the robot grasping position. The loading robot 30 is used to move the parts on the feeding and conveying component 20 to the loading position of the rotary table 60.

[0022] The heating and quenching assembly 50 includes a controller 51, a servo-elevated three-dimensional slide 52, an induction heating device (not shown), and a main water spray device (not shown). The induction heating device is mounted on the moving component of the servo-elevated three-dimensional slide 52. The controller 51 is used to control the servo-elevated three-dimensional slide 52 to move the induction heating device and align it with the part. The controller 51 can also be used to control the operating parameters of the induction heating device. The heating and quenching assembly 50 is used to heat and quench the spherical surface of the spherical bearing. The unloading robot 40 is used to move the heat-treated parts from the rotary table 60 to the discharge conveyor.

[0023] After the parts are loaded, the special machine for fully automatic high-frequency induction heat treatment of spherical joint bearings can automatically complete loading, heating, quenching and unloading without human intervention, realizing fully automatic operation, saving manpower and improving production efficiency.

[0024] The automatic material sorting mechanism 10 includes a turntable automatic material sorting mechanism 11 and a material dividing component 12. During operation, parts only need to be placed in the automatic material sorting mechanism 10 at one time. The turntable of the automatic material sorting mechanism 10 rotates, and the parts are sent to the discharge port through the material dividing component 12 of the automatic material sorting mechanism 10. The feed conveying component 20 conveys the parts from the discharge port of the automatic material sorting mechanism 10 to the robot gripping position. Specifically, in this embodiment, the feed conveying component 20 includes a feed-end push cylinder, a feed conveyor belt, and a positioning tooling provided on the feed conveyor belt. The feed-end push cylinder pushes the parts to the positioning tooling of the feed conveyor belt for clamping and positioning, and then conveys them to the robot gripping position via the feed conveyor belt.

[0025] In this embodiment, the rotary table 60 is a four-station equally divided turntable 60. The four stations of the four-station equally divided turntable 60 are respectively the loading station, the heating and quenching station, the auxiliary cooling station, and the unloading station. The auxiliary cooling station is located between the heating and quenching station and the unloading station. The four-station equally divided turntable 60 is provided with a positioning fixture of a joint bearing for clamping and positioning the parts. The loading robot 30 moves the parts from the robot grasping position on the feed conveyor belt to the positioning fixture of the loading station of the four-station equally divided turntable 60 for clamping and positioning; the turntable of the four-station equally divided turntable 60 rotates and rotates the parts at the loading station to align them to the heating and quenching station.

[0026] The heating and quenching station of the four-station equally divided turntable 60 is equipped with an induction heating device and a main water spraying device. The induction heating device is, for example, a high-frequency induction heater. When the part rotates to the heating and quenching station, the induction heating device moves and aligns with the part, and the induction heating device starts to heat the part. The positioning fixture of the four-station equally divided turntable 60 is connected to a transmission mechanism, such as a chain, and the positioning fixture can rotate under the drive of the transmission mechanism and drive the part to rotate. At the same time as the induction heating device starts to heat the part, the positioning fixture on the turntable of the four-station equally divided turntable 60 is driven by the chain below it, and drives the part to rotate at the speed set by the process, so that the part is heated more fully and evenly. After the heating is completed, the main water spraying device starts to spray water to quench the part; after quenching is completed, the part stops rotating and the heating device returns to its initial position.

[0027] The turntable of the four-station equally divided turntable 60 rotates and indexes, transferring the quenched parts to the auxiliary cooling position. The auxiliary cooling position is equipped with an auxiliary water spray device 62. The auxiliary water spray device 62 is turned on to spray water to further assist in cooling the parts. It can further cold-treat the parts after induction heating quenching, thereby promoting the transformation of retained austenite and further improving the heat treatment performance of the product. In addition, auxiliary cooling can accelerate product cooling, shorten the entire product processing process, and improve production efficiency. Of course, the auxiliary water spray device 62 remains on at the beginning of the process, which is also a feasible technical solution.

[0028] The turntable of the four-station equally divided turntable 60 continues to rotate and index, turning the parts in the auxiliary cooling position to the unloading position, and the unloading manipulator 40 grabs the parts from the turntable to the unloading conveying component 70. The unloading conveying component 70 conveys the parts to the storage bin 80. The discharging conveying component 70 may include a discharging end pushing cylinder, a discharging conveyor belt, and a discharging end baffle provided at the discharging end of the discharging conveyor belt; the discharging end pushing cylinder is provided behind the discharging conveyor belt; the front end of the piston rod of the discharging end pushing cylinder is provided with a pushing plate. After the parts are grabbed by the unloading robot 40 to the discharging conveyor belt, the parts move forward toward the discharging end under the drive of the discharging conveyor belt, and stop moving at the discharging end baffle. Subsequent parts are gradually accumulated thereafter; when a number of parts are accumulated, the discharging end pushing cylinder behind the discharging conveyor belt starts to work, and the accumulated parts are pushed forward into the storage bin 80 at one time through the pushing plate at the front end of the cylinder piston rod, so that the discharging is more regular and more efficient.

[0029] The fully automatic four-station high-frequency induction heat treatment machine for spherical joint bearings can work fully automatically without manual intervention after the parts are loaded.

[0030] The loading robot 30 and unloading robot 40 are fixed to the same slide and driven by a rodless cylinder. Driven by the rodless cylinder, each step progresses. While the loading robot 30 picks up parts from the positioning fixture on the infeed conveyor and places them on the loading position of the four-station equally divided turntable 60, the unloading robot 40 simultaneously picks up quenched parts from the unloading position and moves them to the outfeed conveyor, completing the unloading operation. After completing each mechanical operation, the loading and unloading robots return to their initial positions to prepare for the next operation, resulting in a more streamlined process and time savings.

[0031] The four-station equally divided turntable 60 is also surrounded by inner and outer waterproof covers to prevent the water sprayed by the main water spraying device and the auxiliary water spraying device 62 from entering the interior of the four-station equally divided turntable 60 and causing damage.

[0032] The controller 51 includes a quenching load adjustment module and a servo lifting three-dimensional slide control module. The servo lifting three-dimensional slide 52 can manually or servo-drivenly lift the load, adjust it forward and backward, and adjust it left and right electrically. When the model is switched for the first time, the induction heating device of the corresponding product is first installed, and then the controller 51 and the servo lifting three-dimensional slide 52 are manually adjusted so that the part is centered at the center of the induction coil of the induction heating device. The position coordinates (X, Y, Z) of the induction heating device at this moment are recorded, and the position coordinates (X, Y, Z) are compiled into the process program. The controller 51 is provided with a storage device, which can be used to store the position coordinates of the induction heating device when it is aligned with the part. Each time the program is run, the servo lifting three-dimensional slide 52 can drive the induction heating device to the predetermined position coordinates (X, Y, Z) to ensure the consistency of the gap between the part and the induction coil. Then, by adjusting process parameters such as capacitance, turns ratio, and cooling water system, the power output power of the induction heating device and the flow rate of the main and auxiliary water sprays are controlled to ensure the consistency of the high-frequency quenching quality of the part.
