Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of tooling for disassembling and assembling roll quenching heads, specifically, to a tooling that facilitates the disassembly and assembly of quenching heads. Background Technology

[0002] In the production of rolling mill rolls in the metallurgical industry, the quenching process is a crucial step in ensuring the hardness and wear resistance of the rolls. The rapid assembly and disassembly of the quenching head directly affects production efficiency and process stability. Traditional rolling mill quenching fixtures typically employ a double-layer design with an outer clamping structure and an inner positioning structure for head assembly and disassembly. This necessitates sequentially disassembling the outer and inner components, resulting in a cumbersome and time-consuming process, which has become a technical bottleneck restricting quenching efficiency.

[0003] Traditional tooling typically uses multiple sets of bolts to secure the outer layer to the inner positioning structure. Disassembly requires loosening each outer bolt individually, removing the outer clamping components, and then unlocking the inner positioning structure. This "outer-to-inner" two-layer disassembly method not only increases the workload for operators but also significantly extends the time required for each disassembly / reassembly due to the cumbersome steps. For example, in large roll quenching operations, the disassembly / reassembly of traditional tooling requires multiple steps, and different tools are needed for both the outer and inner layers. Frequent tool switching and component handling can easily lead to operational errors and even damage to the roll surface.

[0004] Furthermore, the double-layered tooling is prone to component wear due to frequent disassembly during long-term use, leading to a decrease in the fitting accuracy between the outer and inner layers, which in turn affects the positioning accuracy during roll quenching. When roll positioning deviates, uneven distribution of the quenched layer becomes a prominent problem, requiring rework in severe cases and further increasing production costs. With the increasing demands for roll production efficiency and quality in the metallurgical industry, the traditional double-layer disassembly and assembly mode is no longer suitable for the needs of large-scale production. Developing a quenching lifting head tooling that enables rapid disassembly and assembly of a single layer is urgently needed. By optimizing the tooling structure and eliminating the separate design of the outer and inner layers, achieving integrated rapid disassembly and assembly of the lifting head is of great significance for improving quenching process efficiency, reducing labor costs, and ensuring the quality of roll quenching. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a tooling that facilitates the disassembly and assembly of the quenching head, which solves the technical problem that the disassembly and assembly of the head of the traditional tooling in the prior art requires multiple operation procedures, and the disassembly of the outer layer and the inner layer requires the use of different tools to alternate operations. Frequent tool switching and component handling can easily lead to operational errors and even cause collision damage to the surface of the roll.

[0006] According to one aspect, at least one embodiment of this disclosure provides a tooling for facilitating the assembly and disassembly of a quenching lifting head, comprising:

[0007] The support base, the front groove, and the rear groove are both formed on the surface of the support base;

[0008] A mounting base and a docking assembly are provided, wherein the mounting base is disposed outside the support base and the docking assembly is disposed between the support base and the mounting base;

[0009] The frame and lifting assembly are provided, wherein the frame is fixed to the side surface of the mounting base and the lifting assembly is mounted on the frame.

[0010] The lifting assembly includes a lifting frame, which is mounted on the outer frame. The lifting frame is provided with a lifting seat, and the surface of the lifting seat has several connecting holes. A vertical screw is rotatably connected inside the outer frame, and the lifting frame and the vertical screw are connected by a threaded engagement.

[0011] As a further technical solution, long slots are provided at both ends of the outer frame surface, and a pair of guide rods are provided in the long slots and in the outer frame. The lifting frame and the vertical screw are connected by a threaded connection.

[0012] As a further technical solution, a first rocker arm is rotatably mounted on the outer side of the outer frame. One end of the first rocker arm and the lower end of the vertical screw are both equipped with transmission gears, both of which are bevel gears.

[0013] As a further technical solution, the docking assembly includes several positioning sleeves, all of which are disposed on the side surface of the support base, and several positioning blocks are disposed on the side surface of the mounting base, all of which are inserted into the positioning sleeves.

[0014] As a further technical solution, the side surface of the support base is provided with an internal threaded sleeve, and the bottom of the mounting base is rotatably connected to a transmission rod. One end of the transmission rod is provided with an external threaded block, and the external threaded block is connected to the internal threaded sleeve by thread screwing.

[0015] As a further technical solution, a second rocking rod is provided at one end of the transmission rod, and a number of movable wheels are provided at the bottom of the mounting base.

[0016] As a further technical solution, both the interior of the mounting base and the bottom surface of the lifting base have an arc-shaped stepped structure.

[0017] As a further technical solution, both the front groove and the rear groove are V-shaped structures, and the height of the rear groove is lower than that of the front groove.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the lifting assembly, through the arc-shaped stepped structure of the lifting base, can simultaneously fit the outer and inner layers of the chuck, and fix them at once with bolts using the connecting holes. This avoids the cumbersome steps of disassembling the outer and inner layers separately, as required by traditional tooling. The cooperation between the vertical screw and the guide rod ensures the smooth movement of the lifting frame and prevents the chuck from shaking during disassembly and assembly, which could damage the surface of the rolls. The bevel gear transmission design allows the operator to easily control the lifting and lowering of the lifting frame by rotating the first rocker arm, reducing labor intensity. This integrated lifting design simplifies the original multiple processes into a single operation, significantly improving the disassembly and assembly efficiency of the quenching lifting head, while reducing operational errors caused by frequent tool switching.

[0020] 2. In this disclosure, the docking assembly achieves rapid positioning of the mounting base and the support base through the precise cooperation of the positioning sleeve and the positioning block, avoiding the complex alignment process in traditional tooling. The design of rotating the second rocker rod to drive the external threaded block into the internal threaded sleeve ensures a stable threaded connection between the mounting base and the support base, preventing loosening during lifting. The movable wheels at the bottom of the mounting base facilitate the operator to push the mounting base for position adjustment, reducing the difficulty of handling. This structural design not only simplifies the assembly steps of the tooling but also improves the matching accuracy between the mounting base and the support base, avoiding the deviation in chuck assembly and disassembly caused by inaccurate positioning, ensuring the positioning accuracy during roll quenching, and extending the service life of the tooling.

[0033] like Figures 1-4 As shown, it illustrates a tooling for facilitating the assembly and disassembly of a quenching lifting head according to an embodiment of this disclosure, comprising:

[0034] The support base 1, the front groove 2 and the rear groove 3 are both formed on the surface of the support base 1;

[0035] Mounting base 4 and docking component 7, wherein the mounting base 4 is disposed outside the support base 1 and the docking component 7 is disposed between the support base 1 and the mounting base 4;

[0036] The outer frame 5 and the lifting assembly 6 are provided. The outer frame 5 is fixed to the side surface of the mounting base 4, and the lifting assembly 6 is mounted on the outer frame 5.

[0037] The lifting assembly 6 includes a lifting frame 6-1, which is mounted on the outer frame 5. A lifting seat 6-2 is mounted on the lifting frame 6-1, and the surface of the lifting seat 6-2 has several connecting holes 6-3. A vertical screw 6-4 is rotatably connected inside the outer frame 5. The lifting frame 6-1 and the vertical screw 6-4 are connected by a threaded connection. Long grooves 6-5 are formed at both ends of the surface of the outer frame 5. A pair of guide rods 6-6 are provided in both the long grooves 6-5 and inside the outer frame 5. The lifting frame 6-1 and the vertical screw 6-4 are connected by a threaded connection. A first rocker arm 6-7 is rotatably mounted on the outer side of the outer frame 5. A transmission gear 6-8 is provided at one end of the first rocker arm 6-7 and at the lower end of the vertical screw 6-4. Both transmission gears 6-8 are bevel gears.

[0038] In some examples, during the disassembly and assembly of the quenching head, a lifting assembly 6 is designed to achieve the effect of disassembling the outer and inner layers of the chuck in one go. This assembly is based on a lifting frame 6-1 set on the outer frame 5. The lifting frame 6-1 can move up and down along the outer frame 5 through the threaded engagement with the vertical screw 6-4 inside the outer frame 5. The guide rods 6-6 in the long grooves 6-5 at both ends of the surface of the outer frame 5 are slidably connected to the lifting frame 6-1 to ensure the stability of the lifting process and avoid shaking. Several connecting holes 6-3 are opened on the surface of the lifting seat 6-2 on the lifting frame 6-1. When the roller with the chuck is placed in the front groove 2 of the support base 1, the lifting seat 6-2 simultaneously fits the outer and inner layers. Bolts can pass through the connecting holes 6-3 to fix the inner and outer layers of the chuck together, forming a stable lifting structure.

[0039] The first rocker arm 6-7 on the outer side of the outer frame 5 meshes with the transmission gear 6-8 at the lower end of the vertical screw 6-4 via a bevel gear. When the first rocker arm 6-7 is rotated, the vertical screw 6-4 rotates synchronously, driving the lifting frame 6-1 to rise or fall, thereby lifting or lowering the clamp.

[0040] Through the threaded transmission of the vertical screw 6-4, the limiting support of the guide rod 6-6, the steering transmission of the bevel gear, and the bolt fixing of the connecting hole 6-3, the lifting assembly 6 realizes the function of fixing the inner and outer layers of the chuck at the connecting hole 6-3 of the lifting seat 6-2 with bolts and cooperating in lifting, providing reliable lifting support for the disassembly and assembly of the quenching lifting head.

[0041] like Figures 1-4 As shown in the figure, the docking assembly 7 in this embodiment includes several positioning sleeves 7-1, all of which are disposed on the side surface of the support base 1. Several positioning blocks 7-2 are disposed on the side surface of the mounting base 4, and the positioning blocks 7-2 are inserted into the positioning sleeves 7-1. An internal threaded sleeve 7-3 is provided on the side surface of the support base 1. A transmission rod 7-4 is rotatably connected to the bottom of the mounting base 4. An external threaded block 7-5 is provided at one end of the transmission rod 7-4. The external threaded block 7-5 is screwed into the internal threaded sleeve 7-3 by thread. A second rocking rod 7-6 is provided at one end of the transmission rod 7-4. Several moving wheels 7-7 are provided at the bottom of the mounting base 4.

[0042] In some examples, a docking assembly 7 is designed to achieve rapid positioning and stable connection between the mounting base 4 and the support base 1. This assembly uses the positioning sleeve 7-1 on the side surface of the support base 1 as a reference. The positioning block 7-2 on the side surface of the mounting base 4 can be accurately inserted into the positioning sleeve 7-1 to form a preliminary positioning fit, ensuring that the relative position of the mounting base 4 and the support base 1 is accurate. The internal threaded sleeve 7-3 on the side surface of the support base 1 and the external threaded block 7-5 at one end of the bottom transmission rod 7-4 of the mounting base 4 are connected by thread screwing. Rotating the second rocker arm 7-6 drives the transmission rod 7-4 to rotate, and the external threaded block 7-5 is screwed into the internal threaded sleeve 7-3, so that the mounting base 4 and the support base 1 are tightly fixed.

[0043] The movable wheels 7-7 at the bottom of the mounting base 4 can push the mounting base 4 to move before docking, so as to facilitate the alignment of the positioning block 7-2 and the positioning sleeve 7-1. After docking, the position is locked by the threaded connection to prevent loosening.

[0044] Through the positioning fit between the positioning sleeve 7-1 and the positioning block 7-2, the fastening connection of the threaded drive, and the auxiliary movement of the moving wheel 7-7, the docking assembly 7 realizes the function of stably connecting the mounting base 4 and the support base 1, ensuring the structural stability of the lifting assembly 6 during operation and facilitating the smooth disassembly and assembly of the quenching lifting head.

[0045] For example, such as Figure 3 As shown, the interior of the mounting base 4 and the bottom surface of the lifting base 6-2 are both arc-shaped stepped structures.

[0046] In some examples, a stepped structure allows the mounting base 4 and the lifting base 6-2 to fully fit the outer and inner layers of the clamp, forming a stable support and lifting mechanism.

[0047] For example, such as Figure 1 As shown, both the front groove 2 and the rear groove 3 are V-shaped structures, and the height of the rear groove 3 is lower than that of the front groove 2.

[0048] In some examples, the V-shaped structure allows the roll to be stably placed in the center. When the roll is lowered, the lower end of the suspended roll first contacts the rear groove 3, and then it is smoothly supported in the front groove 2 when it is tilted down.

[0049] In actual use: The roll is placed in the front groove 2 and rear groove 3 of the support base 1. The V-shaped structure of the front groove 2 and rear groove 3 keeps the roll stably centered. The rear groove 3 is lower than the front groove 2, which facilitates the tilting of the roll. The moving wheel 7-7 pushes the mounting base 4 close to the support base 1. The positioning block 7-2 on the side surface of the mounting base 4 is inserted into the positioning sleeve 7-1 on the side surface of the support base 1 to achieve positioning. Rotating the second rocker arm 7-6 drives the transmission rod 7-4 to rotate, so that the external threaded block 7-5 is screwed into the internal threaded sleeve 7-3, thus aligning the mounting base 4 with the support base. 1. Securely fasten the outer frame 5 to the side surface of the mounting base 4. Rotate the first rocker arm 6-7 to drive the vertical screw 6-4 to rotate through the bevel gear transmission, causing the lifting frame 6-1 to move up and down along the guide rod 6-6. Adjust the lifting base 6-2 to a suitable height. The arc-shaped stepped structure on the bottom surface of the lifting base 6-2 fits the outer and inner layers of the chuck. Fix the inner and outer layers of the chuck to the lifting base 6-2 with bolts through the connecting hole 6-3. Rotate the first rocker arm 6-7 again to raise the lifting frame 6-1, realizing the separation of the chuck and the roller. Reverse the operation to complete the installation.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
