Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ring workpiece machining, in particular to a ring alignment module and device. BACKGROUND

[0002] There are various processes for machining large ring workpieces, such as drilling, turning, grinding, etc. Before machining, alignment is needed to ensure machining accuracy.

[0003] Generally, the traditional method for accurate alignment is copper hammering, but due to factors such as self-weight and tool texture, a damping torque is formed on large workpieces, which easily causes rebound and results in an alignment deviation of 0.1-0.2mm. The alignment accuracy is poor, and it is difficult to align and shift the workpiece. After alignment, radial displacement easily occurs during machining due to the lack of radial clamping constraints, resulting in the production of unqualified products. Multiple same-specification products cannot be stacked and machined, the machining efficiency is low, and the use of a large number of hoisting and clamping auxiliary tools is required, which cannot meet the rapid production demand. SUMMARY

[0004] In view of the defects of the prior art, the present application provides a ring alignment module and device, which can position the workpiece to be machined from the axial and radial directions, can be switched between the first assembly state and the second assembly state at any time, can change the clamping direction, is not affected by the base conditions such as the chuck slot, and greatly improves the flexibility of the device.

[0005] To achieve the above-mentioned purpose, the technical scheme provided by the present application is a ring alignment module, which comprises a base, a positioning plate and an alignment assembly. The base has a first end portion and a second end portion arranged opposite to each other in a first direction, and the first end portion is used for detachable connection with a machining machine tool. The positioning plate is connected with the second end portion, and the positioning plate is provided with an inner clamping slot and an outer clamping slot in a second direction. The alignment assembly comprises an adjusting seat provided with a buckle, a threaded hole penetrating through the adjusting seat in the second direction, an adjusting screw connected with the threaded hole, a threaded blind hole provided in one end of the adjusting screw, and a top block connected with the threaded blind hole. The alignment assembly has a first assembly state and a second assembly state on the positioning plate. When in the first assembly state, the buckle is clamped with the inner clamping slot. When in the second assembly state, the buckle is clamped with the outer clamping slot. The first direction is perpendicular to the second direction.

[0006] Further, the positioning plate and the second end portion are connected by a pin hole type connection.

[0007] Further, the first direction is the axial direction of the ring, and the second direction is the radial direction of the ring.

[0008] Furthermore, both the inner and outer card slots are L-shaped and are arranged opposite to each other in the second direction; the buckle is L-shaped and is arranged opposite to the top block.

[0009] Furthermore, an oil reservoir is provided in the middle of the threaded hole, and the oil reservoir provides a cavity for containing lubricating oil.

[0010] Furthermore, the top block includes a connecting portion connected to the threaded blind hole and a top head protruding from the adjusting seat.

[0011] Preferably, the top head is hemispherical or elongated arc-shaped.

[0012] Furthermore, the other end of the adjusting screw extends from the threaded hole of the adjusting seat and is connected to a force-applying component.

[0013] Preferably, the force-applying component includes a wrench.

[0014] A ring alignment device includes a ring alignment module as described above.

[0015] Furthermore, it also includes a chuck, which has multiple mounting grooves, and the ring alignment module is connected to the mounting grooves.

[0016] The beneficial effects of this invention are as follows: The device can simultaneously perform three functions: support, alignment, and radial clamping. During operation, the workpiece's self-weight is converted into axial force to constrain the positioning plate, preventing axial displacement of the positioning plate. The magnitude of the constraint force is determined by the workpiece's self-weight, and this ingenious conversion allows the workpiece to slide freely on the positioning plate. An adjusting screw is used to transmit radial displacement, pushing the workpiece for alignment. The positioning plate has an inner and outer locking groove in the second direction x. Both the inner and outer locking grooves can hook and engage with the buckle. Firstly, the alignment component and the positioning plate are connected by a hook-type connection. During application, as the force increases, the reaction force causes the hook to tighten, eliminating the risk of disengagement or failure. Secondly, it can switch between the first and second assembly states at any time, changing the clamping direction without being affected by the base working conditions such as the chuck and slots. In the ring alignment module, the positioning plate and the adjusting seat are interconnected, and the adjusting seat can be arbitrarily disassembled and added to cope with different working conditions, greatly improving the flexibility of the device.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See Figure 1 and Figure 2 In one embodiment of the present invention, a ring alignment module 10 is applied to large ring-shaped workpieces, such as teeth, holes, turning and other precision machining processes. It includes a base 100, a positioning plate 200 and an alignment component 300. The alignment component 300 is connected to the base 100 through the positioning plate 200 and is used to align the workpiece.

[0029] The base 100 has a first end 110 and a second end 120 disposed opposite to each other in the first direction y, the first end 110 being used for detachable connection with a machine tool; such as Figure 1As shown, in this embodiment, the base 100 is an auxiliary support leg, which is connected to the chuck of the machine tool. In other embodiments, the base 100 is a chuck, the intermediate auxiliary support leg is omitted, and the positioning plate 200 is directly connected to the chuck. The positioning plate 200 is connected to the second end 120 of the base 100, and the positioning plate 200 has an inner groove 210 and an outer groove 220 in the second direction x; the alignment component 300 includes an adjusting seat 310 with a buckle 311, a threaded hole 312 passing through the adjusting seat 310 in the second direction x, an adjusting screw 313 connected to the threaded hole 312, a threaded blind hole 3131 at one end of the adjusting screw 313, and a top block 314 connected to the threaded blind hole 3131.

[0030] See Figure 3 and Figure 4 The alignment component 300 has a first assembly state and a second assembly state on the positioning plate 200; when it is in the first assembly state, the buckle 311 engages with the inner slot 210; when it is in the second assembly state, the buckle 311 engages with the outer slot 220; the first direction y is perpendicular to the second direction x.

[0031] The aforementioned ring alignment module 10 can perform three functions: support, alignment, and radial clamping. During operation, it converts the workpiece's own weight into axial force to constrain the positioning plate 200, preventing axial displacement of the positioning plate 200. The magnitude of the constraint force is determined by the workpiece's own weight, and this ingenious conversion allows the workpiece to slide freely on the positioning plate 200. An adjusting screw 313 is used to transmit radial displacement, pushing the workpiece for alignment. The adjusting screw 313 has high adjustment precision and can achieve stepless adjustment. Specifically, a trapezoidal screw can be selected for the adjusting screw 313. The positioning plate 200 has an inner slot 210 and an outer slot 220 in the second direction x. Both the inner slot 210 and the outer slot 220 can hook and engage with the buckle 311. First, the alignment component 300 and the positioning plate 200 are connected by a hook. During application, as the force increases, the reaction force causes the hook to tighten, eliminating the risk of disengagement or failure. Second, it can switch between the first and second assembly states at any time, changing the mounting direction without being affected by the working conditions of the chuck or slot. In the ring alignment module 10, the positioning plate 200 and the adjusting seat 310 are interconnected, and the adjusting seat 310 can be arbitrarily disassembled and added to adapt to different working conditions, greatly improving the flexibility of the device. In addition, the ring alignment module 10 is lightweight, flexible in use, can be operated by one person, and can be moved as needed.

[0032] See Figure 3 and Figure 4As a preferred embodiment, in one embodiment, the positioning plate 200 and the second end 120 of the base 100 are connected by a pin hole. Specifically, 4-6 shallow blind holes can be opened on the base 100, and corresponding through holes can be opened on the positioning plate 200. The positioning pin 121 is used to fix the positioning plate 200 on the base 100. In this way, during operation, the weight of the workpiece is converted into an axial force to constrain the positioning plate 200 and prevent the positioning plate 200 from axial displacement. The magnitude of the constraint force is determined by the weight of the workpiece. This ingenious conversion allows the workpiece to slide freely on the positioning plate 200.

[0033] It should be noted that before the improvement, when the workpiece was placed on the bracket, although gravity would be converted into axial force, the bracket was bolted to the chuck. The bolted connection constrained both radial and lateral displacement, so this converted axial force was meaningless. Instead, the resistance generated by the tool marks (machining texture) would make radial alignment difficult. After the improvement, since the workpiece is placed on the positioning plate 200, which is connected to the base 100 by a pin hole, the workpiece's own weight constrains the axial movement of the positioning plate 200. The magnitude of the constraint force is determined by the workpiece's own weight. The positioning pin 121 inserted into the positioning plate 200 is used to constrain the radial displacement of the positioning plate. During alignment, the workpiece is tapped to make it move correctly, thus achieving the alignment purpose.

[0034] See Figure 2 In one embodiment, both the inner slot 210 and the outer slot 220 are L-shaped and are positioned opposite each other in the second direction x; the buckle 311 is L-shaped and is positioned opposite to the top block 314. Using this method, the inner slot 210 and the buckle 311 are connected by a hook. During application, as the force increases, the reaction force causes the hook to tighten, eliminating the possibility of disengagement or failure.

[0035] In one embodiment, the first direction y is the axial direction of the ring, and the second direction x is the radial direction of the ring.

[0036] See Figure 1 In one embodiment, an oil reservoir 3121 is provided in the middle of the threaded hole 312, and the oil reservoir 3121 provides a cavity for containing lubricating oil. In this way, the oil reservoir 3121 designed between the internal threads on both sides can self-lubricate as the adjusting screw 313 moves, reduce the risk of damage to the adjusting screw 313, make the operation smoother, and thus extend the service life of the device.

[0037] In one embodiment, the top block 314 includes a connecting portion 3141 connected to the threaded blind hole 3141 and a top head 3142 protruding from the adjusting seat 310. The top head 3142, at the contact portion with the workpiece, can be configured in hemispherical, elongated arc, or other shapes and lengths, depending on the workpiece wall thickness and degree of deformation, and can be freely switched to reduce the risk of product deformation. Preferably, in some embodiments, such as... Figure 1As shown, for workpieces with large tonnage, spherical point contact is more conducive to moving the workpiece and improving the alignment accuracy. In other embodiments, for easily deformable workpieces, a long arc-shaped mandrel can be used to make multi-point self-centering contact with the workpiece to correct it, and it is less likely to cause damage or deformation to the workpiece.

[0038] It should be noted that during alignment, the dial indicator on the magnetic gauge holder displays the current value in real time. The alignment component 300 uses this current value to perform radial alignment to the optimal value. Because the adjusting screw 313 and the mandrel 314 can transmit a minute displacement to the workpiece, the alignment accuracy is naturally high. Since the mandrel 314 always acts radially on the workpiece, it ensures that the workpiece does not shift during processing. The mandrel 3142 at the end of the mandrel 314 can correct elastic deformation to a certain extent, that is, correct the deformation of thin-walled workpieces caused by hoisting, damping forces generated by contact with the support surface, etc. The elastic deformation is released by displacing the workpiece through the mandrel 3142, while the workpiece's own plastic deformation is truly presented, without affecting the processing result of this process or being transmitted to subsequent processes.

[0039] See Figure 3 and Figure 4 In one embodiment, the other end of the adjusting screw 313 extends from the threaded hole 312 of the adjusting seat 310 and is connected to a force-applying member 3132. See also, as an example... Figure 2 The force-applying component 3132 includes a wrench fixed to the end of the adjusting screw 313. It should be noted that the form of the force-applying component 3132 is not limited and can be any structure that facilitates the application of force, such as a handwheel or a handle.

[0040] See Figure 5 and Figure 6 In one embodiment, a ring alignment device 1 is applied to a gear milling machine and includes the ring alignment module 10 as described above. Based on this embodiment, the ring alignment device 1 further includes a chuck 20, which has multiple mounting grooves 21, and the ring alignment modules 10 are connected to the mounting grooves 21. Three or four ring alignment modules 10 are detachably fixed to the upper part of the chuck 20.

[0041] The aforementioned ring alignment device 1 provides both height equalization and support, utilizing the workpiece's own weight for axial positioning and constraint. It achieves high alignment accuracy. Calculations show that compared to traditional alignment jaw devices and hammer striking, single-piece alignment efficiency can be increased by 63%, and alignment accuracy improved to within 0.02mm. This reduces quality risks, effectively prevents workpiece displacement during processing, and ensures that evaluation indicators such as workpiece end face runout and flatness are fully met. Furthermore, the ring alignment device 1 can rely on the radial position of the first piece to center the subsequent pieces (deviation less than 0.15mm).
