Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surface quenching treatment equipment, in particular to a quenching machine table for guiding wheel surface treatment. BACKGROUND

[0002] The guide wheels often used in engineering machinery need to be quenched on the surface of the outer circle to improve the mechanical properties of the guide wheels, and most of the guide wheels are double-head symmetrical structures, and a small part of the multifunctional guide wheels have different outer diameters at the two ends to adapt to different guiding functions.

[0003] In the prior art, the quenching of the guide wheel is mostly one-sided quenching, or single-head quenching. After quenching one end, the guide wheel is flipped over for quenching the opposite end. The quenching equipment includes an inner ring turntable, an inner ring lifting device, an outer ring heating device, etc. The top of the inner ring turntable is provided with a jaw for supporting and fixing the guide wheel and rotating the guide wheel in place during quenching. The inner ring lifting device supports and lifts the inner ring turntable to lower the guide wheel into the cooling tank below after quenching, and cooperates with the cooling liquid for cooling. When the other end of the guide wheel needs to be processed, a mechanical arm is used to hold the guide wheel for 180-degree flipping and then placed back on the inner ring turntable, and then clamped and fixed by the jaw again. The outer ring heating device is used to heat the outer surface of the guide wheel.

[0004] However, during long-term use, it is found that:

[0026] With reference to Figure 1 and Figure 2 , the embodiments of the present application provide a quenching machine for guiding wheel surface treatment, comprising a machine base 10, an inner ring rotating disc 20 and an outer ring lifting frame, wherein the inner ring rotating disc 20 is rotatably arranged at the center position of the machine base 10 and is provided with a claw (not shown in the figure) for fixing the guiding wheel at the top, wherein the inner ring rotating disc 20 can be driven to rotate horizontally in place by a rotating shaft connected vertically at the bottom and a rotating motor, wherein a plurality of claws (such as three claws) are embedded in the axle hole of the guiding wheel in cooperation, and then move outward synchronously to tighten and fix the guiding wheel; the outer ring lifting frame comprises an upper mounting frame 30 and a lower mounting frame 40, wherein the upper mounting frame 30 and the lower mounting frame 40 are arranged in a movable manner at the outer ring of the machine base 10, and the upper mounting frame 30 is closer to the outer side of the machine base 10 than the lower mounting frame 40, so as to form a staggered position in the horizontal direction, which can facilitate the installation of the extension cylinder used to drive the upper mounting frame 30 and the lower mounting frame 40 in the subsequent process, and avoid installation interference, in addition, the upper mounting frame 30 and the lower mounting frame 40 are respectively and uniformly mounted with a plurality of first heating elements 31 and a plurality of second heating elements 41 extending in the horizontal direction and movable horizontally in the circumferential direction, and the first heating elements 31 and the second heating elements 41 are opposite to the center of the machine base 10, and the upper mounting frame 0 and the lower mounting frame 40 are respectively further provided with a first nozzle 32 and a second nozzle 42 for spraying cooling liquid to the surface of the guiding wheel after heating.

[0027] Thus, in the quenching machine provided by the present application for guiding wheel surface treatment, on the one hand, the upper mounting frame 30 and the lower mounting frame 40 can respectively drive all the first heating elements 31 and all the second heating elements 41 to move up and down, thereby quenching the opposite two end faces of the guiding wheel through the first heating elements 31 and the second heating elements 41 at the same time, without the need for turning operation, which can improve work efficiency, reduce equipment occupied space, and save equipment cost, and based on the design that the distance between the first heating elements 31 and the second heating elements 41 is adjustable, different length guiding wheels can also be quenched, or only one end face of the guiding wheel is quenched, on the second hand, since the first heating elements 31 and the second heating elements 41 can respectively move in the horizontal direction, different outer diameter specifications of guiding wheels can be quenched, which is especially suitable for simultaneously quenching multifunctional guiding wheels with different end head outer diameters, only the distance between the first heating elements 31 and the second heating elements 41 and the elongation position in the horizontal direction need to be adjusted, which is very convenient to use, and the application range is more extensive, on the third hand, the first nozzle 32 and the second nozzle 42 are respectively installed on the upper mounting frame 30 and the lower mounting frame 40, and can move with the upper mounting frame 30 and the lower mounting frame 40, that is, the first nozzle 32 and the second nozzle 42 always maintain the same height position with the first heating elements 31 and the second heating elements 41, and are also distributed in the horizontal direction, so that when the first heating elements 31 and the second heating elements 41 are heated, since the first nozzle 32 and the second nozzle 42 maintain the same height position with the first heating elements 31 and the second heating elements 41, cooling treatment can be immediately performed without any turning, lifting or moving operation, and the waiting time is extremely short, and this distribution form and working mode are not limited to simultaneously quenching both ends of the guiding wheel or separately quenching any one end of the guiding wheel.

[0028] In one embodiment, the top of the inner ring turntable 20 is detachably mounted with an adapter table 21, and the clamping jaws are mounted on the top of the adapter table 21, so that additional height support can be provided through the adapter table 21, so that the guiding wheel can protrude from the machine seat 10 and can be better quenched, and in addition, when different specifications of guiding wheels need to be processed, the adapter table 21 with different specifications of clamping jaws can also be flexibly replaced, which can further improve work efficiency.

The first telescopic cylinder 13 and the second telescopic cylinder 14 can be distributed on the six columns 12, or they can be selectively arranged on the six columns 12, as long as they can work together to synchronously drive the upper mounting frame 30 and the lower mounting frame 40 to move up and down.

[0034] More preferably, a first reinforcing rib 121 and a second reinforcing rib 122 are connected between the top and bottom of adjacent columns 12, respectively. At the same time, the first reinforcing ribs 121 and the second reinforcing ribs 122 respectively form a regular hexagon corresponding to the upper mounting frame 30 and the lower mounting frame 40, thereby further strengthening the stability of the six columns 12 and ensuring the reliability of the quenching machine.

At the same time, the first heating element 31 and the second heating element 41 are respectively installed on the inner pushing ends of the first electric push rod 34 and the second electric push rod 44, so that the first heating element 31 and the second heating element 41 can be driven by the first electric push rod 34 and the second electric push rod 44 to be oriented horizontally toward or away from the center of the machine base 10.

[0036] More preferably, the first electric push rod 34 and the second electric push rod 44 are both fixedly mounted on the upper mounting bracket 30 and the lower mounting bracket 40 via mounting plate 35. The first electric push rod 34 and the second electric push rod 44 vertically penetrate the mounting plate 35 and are connected to a transition block 36 after penetration. A guide rod 37 is vertically connected to the outer side of the transition block 36, and the guide rod 37 slides in engagement with the mounting plate 35. The first heating element 31 and the second heating element 41 are mounted on the inner side of the transition block 36. This allows the guide rod 37 and the mounting plate 35 to provide guidance, ensuring the accuracy of the movement direction of the first heating element 31 and the second heating element 41, thereby ensuring the quenching quality.

[0037] It should be noted that the quenching machine provided in the present application also contains an electric control cabinet, wherein each controllable electrical element is controlled by the electric control cabinet, such as the pushing time and pushing length of the first electric push rod 34 and the second electric push rod 44, and also such as the electric control cabinet controls the first telescopic cylinder 13 and the second telescopic cylinder 14 through the electric control valve of the first telescopic cylinder 13 and the second telescopic cylinder 14 to control the extension time and extension amount of the first telescopic cylinder 13 and the second telescopic cylinder 14, wherein the first telescopic cylinder 13 and the second telescopic cylinder 14 can be hydraulic cylinders or electric cylinders, and also such as controlling the first heating element 31 and the second heating element 41, etc., the above controls all belong to the conventional technology, and the control principle will not be described in detail here.
