[0022] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0023] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0024] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0025] refer to Figures 1 to 4 , a multi-chamber graded positioning spray device according to a preferred embodiment of the utility model will be described in detail below, wherein the multi-chamber graded positioning spray device specifically includes a base frame 10, a positioning rotating mechanism 20 and a multi-chamber sprayer 30, wherein the positioning rotating mechanism 20 includes a positioning member 21, a passive rotating member 22 and an active rotating member 23, wherein the positioning member 21 is installed on the top of the base frame 10, and the top of the positioning member 21 is provided with an arc-shaped groove 201 that matches the middle part 41 of the wheel body of the supporting wheel 40, for supporting and placing the supporting wheel 40, wherein in order to save materials and facilitate installation, the positioning member 21 includes an arc-shaped positioning plate 211 and two support rods 212, wherein the two ends of the arc-shaped positioning plate 211 are bent outward and obliquely upward along the arc surface to form the arc-shaped groove 201, and the two support rods 212 are symmetrically connected between the two ends of the arc-shaped positioning plate 211 and the base frame 10 in a supporting manner.

[0026] The passive rotating member 22 and the active rotating member 23 are respectively located on both sides of the positioning member 21 and are installed on the base frame 10 in a relatively close or distant manner so as to be inserted into the wheel axle cavity of the supporting wheel 40 on both sides to support and rotate the supporting wheel 40. That is to say, the active rotating member 23 and the passive rotating member 22 cooperate with each other to support the supporting roller 40 at both ends of the wheel axle cavity of the supporting roller 40 respectively. At the same time, the active rotating member 23 acts as a force-applying body to actively rotate the supporting roller 40, and the passive rotating member 22 acts as a passive rotating body, which can cooperate with the active rotating member 23 to bear most of the weight of the supporting roller 40 without affecting the free rotation of the supporting roller 40. The positioning member 21 mainly plays a positioning role by cooperating with the middle part 41 of the wheel body of the supporting roller 40, and basically does not share the weight of the supporting roller 40. Therefore, the positioning member 21 is implemented as an arc-shaped positioning plate 211, which cooperates with two support rods 212 to effectively position the supporting roller 40. At the same time, less consumables are used, the cost is low, and it is easy to maintain.

[0027] The multi-chamber sprinkler 30 includes a water jacket 31 and a pressure sensor, wherein the water jacket 31 is installed on the base frame 10 and is located below the positioning member 21, and the water jacket 31 is provided with different water pressure chambers corresponding to different outer shapes of the supporting roller 40, and the pressure sensors are respectively arranged in different water pressure chambers and connected to a controller, so that the spraying pressure of different water pressure chambers can be adjusted and controlled by the controller in stages to spray to different outer shapes of the supporting roller 40 through the water spray holes of different water pressure chambers. For example, the supporting roller 40 usually includes a middle wheel body portion 41 in the middle, which is used to cooperate with the positioning member 21 to complete the positioning, and also includes a raised step portion 42 symmetrically arranged at both ends of the wheel body middle portion 41, which has different protruding heights. If a conventional single-chamber water jacket is used, then based on the single and only spray water pressure of the single chamber, the spray quenching quality of the raised step portion 42 will inevitably be affected. Therefore, in the present application, the water jacket 31 can be provided with different water pressure chambers corresponding to the raised step 42 of the supporting roller 40, and different water pressure chambers are for One or more rows of water spray holes are arranged on the surface of the roller 40 at the same height position, and the water inlet hole of the hydraulic chamber can be arranged on the outer surface of the water jacket 31 or on the side of the water jacket 31. It is not so important. The pressure of the hydraulic chamber corresponding to the more protruding part is smaller, that is, a graded and adjustable hydraulic chamber is arranged based on the distance between the water jacket 31 and the surface of the roller 40, so that the water spray pressure on the different concave and convex surfaces of the roller 40 is the same, which can effectively ensure the spray quenching quality of products with special-shaped structures such as the roller 40. Obviously, the above is only for illustration. For other engineering machinery products that may have other shapes, it is only necessary to set hydraulic chambers with different pressures corresponding to different heights. In general, the positioning spray device proposed in this application is suitable for products with consistent local heights. If it has a very dense concave and convex structure in a small area, it may not be suitable.

[0028] A PLC control system can be installed in the controller, which receives signals from the water pressure sensor and further adjusts the pressure in different water pressure chambers in stages by controlling the water inlet.

[0029] In one embodiment, the passive rotating member 22 includes a rotating head 221, a mounting seat 222 and a telescopic cylinder 223, wherein the telescopic cylinder 223 is fixedly mounted on the base frame 10, and the mounting seat 222 is connected to the telescopic end of the telescopic cylinder 223 in a manner that it can be driven and moved in a directional manner, and the rotating head 221 is mounted on the other end of the mounting seat 222 relative to the telescopic cylinder 223 through a bearing, and the rotating head 221 cooperates with the wheel axle cavity of the supporting wheel 40. In this way, the position of the mounting seat 222 can be flexibly adjusted through the telescopic cylinder 223, so that the rotating head 221 can be inserted into the wheel axle cavity of the supporting wheel 40, and cooperate with the active rotating member 23 to rotate and support the supporting wheel 40. Under the action of the bearing in the mounting seat 222, the rotating head 221 can rotate freely.

[0030] Further preferably, the base frame 10 is provided with a guide rail 11 below the mounting seat 222, wherein the guide rail 11 extends along the moving direction of the mounting seat 222, and at the same time, a slider 224 matching with the guide rail 11 is provided at the bottom of the mounting seat 222, so that based on the matching relationship between the guide rail 11 and the slider 224 and the directional extension and retraction of the telescopic cylinder 223, the accuracy of the moving direction of the mounting seat 222 can be further ensured, so that the rotating head 221 can be accurately inserted into the wheel axle cavity without scratching the surface of the supporting wheel 40 during the insertion process.

[0031] In one embodiment, the active rotating member 23 includes a flip seat 231, a flip cylinder 232, a rotating element 233 and an active rotating shaft 234, wherein the flip seat 231 is hingedly mounted on the top of the base frame 10 and close to an end of the base frame 10 away from the telescopic cylinder 223, wherein the fixed portion of the flip cylinder 232 is hingedly arranged at the bottom of the base frame 10, and the telescopic portion of the flip cylinder 232 is hingedly connected to the outer side of the flip seat 231, so that the flip seat 231 can be driven when extended, so that the horizontal bottom of the flip seat 231 abuts against the bottom of the base frame 10. The horizontal top completes the flip positioning of the flip seat 231, wherein the rotating element 233 is fixedly mounted on the outer side of the flip seat 231, and the output end of the rotating element 233 is connected to a reducer 235, wherein the active rotating shaft 234 vertically penetrates the outer side of the flip seat 231 through a bearing in a rotatable manner, and the active rotating shaft 234 is connected to the output shaft of the reducer 235 through a transmission member. In addition, the active rotating shaft 234 cooperates with the wheel axle cavity on the other side of the supporting roller 40, and can cooperate with the passive rotating member 22 to support the supporting roller 40 while also rotating the supporting roller 40.

[0032] During operation, the active rotating shaft 234 on the flip seat 231 remains in a vertically extended state. The supporting roller 40 is first sleeved on the active rotating shaft 234 by the manipulator, and then the flip cylinder 232 is extended to push the flip seat 231 to flip upward with the hinge shaft or hinge joint 12 on the base frame 10 as the hinge fulcrum, until the horizontal bottom of the flip seat 231 abuts against the horizontal top of the base frame 10 to complete the positioning. Since the supporting roller 40 is sleeved on the active rotating shaft 234, the extension speed of the flip cylinder 232 is slow. During the flipping process, the supporting roller 40 will not slide out and separate from the active rotating shaft 234. After flipping into place, the telescopic cylinder 223 is extended to insert the rotating head 221 into the wheel axle cavity on the other side of the supporting roller 40, and cooperate with the positioning piece 21 to complete the positioning and support of the supporting roller 40. Thereafter, the rotating element 233 drives the supporting roller 40 to rotate through the active rotating shaft 234, and the water jacket 31 begins to spray quench the surface of the supporting roller 40.

[0033] The rotating element 233 is implemented as a servomotor.

[0034] In one embodiment, the transmission member includes a driving gear 51, a passive gear 52 and a transmission chain, wherein the driving gear 51 is coaxially sleeved on the output shaft of the reducer 235, wherein the passive gear 52 is coaxially sleeved on the outer side of the flip seat 231 on the driving rotating shaft 234, and the transmission chain is simultaneously sleeved on the driving gear 51 and the passive gear 52 to achieve a transmission connection, and the transmission is more stable, thereby accurately controlling the rotation speed and rotation direction of the driving rotating shaft 234 by means of meshing transmission of gears and transmission chains.

[0035] In one embodiment, there are two water jackets 31 , and the two water jackets 31 are symmetrically distributed on both sides of the positioning member 21 , so that the raised steps 42 on both sides of the supporting wheel 40 can be spray quenched at the same time.

[0036] Further preferably, the positioning and rotating mechanism 20 and the multi-cavity sprayer 30 are each provided with multiple groups, that is, each multi-cavity sprayer 30 and the positioning and rotating mechanism 20 is taken as a group, and a roller 40 is positioned, supported and rotated by the positioning member 21, the passive rotating member 22 and the active rotating member 23, and the water jacket 31 sprays and quenches the roller 40 at the same time, and in the present application, multiple water jackets 31 spray and quench the rollers 40 on multiple positioning and rotating mechanisms 20 respectively. Taking four groups of positioning and rotating mechanisms 20 and multi-cavity sprayers 30 as an example, during operation, two of the rollers 40 are placed on two groups of equipment near one end by a robotic arm for rotary spray quenching. After completion, the other two groups of equipment successively perform rotary spray quenching in the same manner, and the four stations work alternately in pairs, which can avoid the waste of waiting time and greatly improve work efficiency.

[0037] In addition, in order to further save equipment costs, in the four sets of positioning rotating mechanisms 20 and the multi-chamber sprayer 30, only one rotating element 233 and one reducer 235 can be set near one end respectively. The rotating element 233 drives the reducer 235 to rotate. The two active gears 51 on the reducer 235 respectively drive the passive gears 52 on both sides to rotate through the transmission chain, and the passive gears 52 on both sides are coaxially sleeved on the active rotating shafts 234 on both sides, thereby allowing a servo motor to drive the two supporting wheels 40 to rotate synchronously.

[0038] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
