[0002] At present, wheel hub anti-slip ring products are increasingly recognized by the market for their beautiful and personalized shapes. Anti-slip ring products are usually annular thin sheet structures, and high requirements are placed on the clamping and positioning devices of the anti-slip rings during machining operations. If the positioning and clamping are improper, problems such as product deformation and dimensional deviation are likely to occur, and even waste products may be generated, and the processing quality cannot be effectively guaranteed.

[0003] The patent document with the announcement number CN212286793U discloses a positioning tool for anti-slip ring machining, which uses 2 clamping jaws and 16 positioning blocks to position and clamp the anti-slip ring. In actual application, the anti-slip ring is prone to deformation during the clamping process due to the small number of clamping jaws, causing the parts far away from the clamping jaws to be lifted to varying degrees, affecting the processing accuracy. At the same time, the anti-slip ring cannot be completely attached to the positioning block, and the tool is prone to vibration during the processing, and the processing quality cannot be guaranteed; the production, assembly, and adjustment of the 16 positioning blocks in this scheme are troublesome, time-consuming and labor-intensive; in addition, the clamping jaws in this scheme can only clamp the anti-slip ring in one direction from the outer diameter direction of the anti-slip ring, interfering with the outer diameter processing of the anti-slip ring, and cannot complete the one-time positioning and clamping, and the inner and outer diameters of the anti-slip ring can be processed simultaneously, resulting in low operating efficiency and low secondary positioning processing accuracy.

[0004] Based on this, developing a new type of anti-ring-off machining positioning tooling for application in actual production is an urgent problem to be solved. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning tool for anti-ring-off machining in order to solve the problem that the existing anti-ring-off positioning device has low positioning accuracy and cannot guarantee the processing quality, and at the same time solve the problem that the existing positioning device is time-consuming and labor-intensive to use and has low operating efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] Preferably, the lifting and lowering claw is provided with a pressing column for contacting and pressing the anti-slip ring, and the pressing column is made of non-metallic material to avoid crushing the anti-slip ring, and the pressing column is made of nylon or polyurethane material.

[0010] Preferably, a clamping groove is radially opened on the bottom plate and passes through the bottom plate, and a threaded hole is opened at the bottom of the rotating oil cylinder corresponding to the clamping groove. The locking bolt passes through the clamping groove from the bottom surface of the bottom plate and is screwed into the threaded hole, so that the rotating oil cylinder can be slidably connected in the clamping groove through the locking bolt, thereby realizing the position adjustment of the lifting and lowering pressure claws.

[0011] Preferably, the clamping groove spans the inner diameter of the anti-slip ring in the length direction and extends to a central position close to the bottom plate, so that the lifting and lowering pressing claws can be arranged in the inner diameter direction of the anti-slip ring to clamp the anti-slip ring.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1-2 As shown, a positioning tool for machining an anti-slip ring 5 includes a base plate 1 for connecting to a processing platform, and a plurality of support blocks 2 are fixedly arranged on the base plate 1, and the support blocks 2 are fan-shaped structures arranged at equal intervals in the circumferential direction. A gasket 3 is arranged on the support block 2 corresponding to the anti-slip ring 5 workpiece, which is used for positioning and clamping the anti-slip ring 5. A lifting and pressing claw 4 is arranged on the base plate 1 corresponding to the anti-slip ring 5 product on the gasket 3. When in use, the positioning tool is fixedly connected to the processing platform through the base plate 1, and the anti-slip ring 5 workpiece is placed on the gasket 3 to complete the positioning of the anti-slip ring 5 product. At this time, the lifting and pressing claw 4 descends and presses on the upper end face of the anti-slip ring 5 to complete the pressing and clamping of the anti-slip ring 5 workpiece.

[0025] In order to improve the problem in the prior art that the anti-slip ring 5 is not clamped tightly and is prone to warping and deformation, in this embodiment, multiple groups of lifting and pressing claws 4 are arranged along the circumference of the anti-slip ring 5, which can simultaneously apply clamping force to multiple circumferential points of the anti-slip ring 5, press the anti-slip ring 5 tightly against the gasket ring 3, avoid the deformation of the anti-slip ring 5, and enhance the clamping reliability of the anti-slip ring 5.

[0026] As a preferred embodiment, the lifting and pressing claw 4 is connected to the base plate 1 through a rotating oil cylinder 41, so that the lifting and pressing claw 4 has the function of rotating in the horizontal direction to avoid interfering with the positioning of the anti-slip ring 5. When the anti-slip ring 5 workpiece is ready to be clamped, the lifting and pressing claw 4 is in a raised state driven by the rotating oil cylinder 41, and the length direction of the lifting and pressing claw 4 is parallel to the tangent direction of the outer diameter of the anti-slip ring 5 workpiece. At this time, the lifting and pressing claw 4 that deviates from the clamping position of the anti-slip ring 5 no longer interferes with the positioning and placement of the anti-slip ring 5. After the positioning is completed, the rotating oil cylinder 41 drives the lifting and pressing claw 4 to rotate inward corresponding to the anti-slip ring 5 workpiece, and descends and presses on the anti-slip ring 5 to complete the positioning and clamping of the workpiece. This embodiment facilitates the positioning and clamping operation of the anti-slip ring 5 and improves the efficiency of loading and unloading workpieces.

[0027] Furthermore, the lifting and lowering claw 4 is provided with a pressing column 42 for contacting and pressing the anti-slip ring 5, and the pressing column 42 is made of non-metallic material to protect the anti-slip ring 5 and avoid crushing the anti-slip ring 5 during the pressing process. The pressing column 42 can be preferably made of non-metallic materials such as nylon and polyurethane.

[0028] In a further embodiment, the lifting and lowering claw 4 has horizontal freedom relative to the anti-slip ring 5 on the bottom plate 1, so that the lifting and lowering claw 4 can be adapted to anti-slip rings 5 ​​of different sizes for positioning and clamping, thereby improving the versatility of the positioning tooling. Specifically, a clamping groove 11 is radially provided on the bottom plate 1 and penetrates the bottom plate 1, and a threaded hole is provided at the bottom of the rotating oil cylinder 41 corresponding to the clamping groove 11. The locking bolt penetrates the clamping groove 11 from the bottom surface of the bottom plate 1 and is screwed into the threaded hole, so that the rotating oil cylinder 41 can be slidably connected in the clamping groove 11 through the locking bolt, thereby realizing the position adjustment of the lifting and lowering claw 4.

[0029] Furthermore, the clamping chute 11 spans the inner diameter of the anti-slip ring 5 in the length direction and extends to the center position close to the bottom plate 1, so that the lifting and lowering pressure claws 4 can be arranged in the inner diameter direction of the anti-slip ring 5 to clamp the anti-slip ring 5. During operation, the locking bolt is removed to move the rotating oil cylinder 41 from the outer diameter direction to the inner diameter direction and re-lock and fix it, so that the anti-slip ring 5 can be clamped from the inside to the outside quickly. The problem of the lifting and lowering pressure claws 4 interfering with the outer diameter processing of the anti-slip ring 5 is avoided, so that the processing of the anti-slip ring 5 is freed from the trouble of secondary positioning and re-alignment, and the inner and outer diameter processing can be completed, which further improves the processing efficiency and ensures the processing accuracy.

[0030] As a preferred embodiment, the backing ring 3 is configured with multiple sets corresponding to the anti-slip rings 5 ​​of different specifications, and the backing ring 3 is detachably connected to the support block 2. When processing different anti-slip rings 5, the positioning and clamping of the anti-slip rings 5 ​​of different specifications can be completed by simply replacing the corresponding backing rings 3, further improving the applicability of the positioning tooling.

[0031] Preferably, the gasket 3 is provided with a connection hole 31 for connecting the support block 2, the connection hole 31 is coaxially provided with a countersunk hole 32, and the support block 2 is provided with a connection notch 33 radially corresponding to the connection hole 31, and the connection bolt 34 lying in the countersunk hole 32 of the connection hole 31 penetrates the connection hole 31 and the connection notch 33 of the support block 2, and is screwed on the locking nut to achieve the connection and fixation of the gasket 3 and the support block 2. When processing anti-slip rings 5 ​​of different specifications, the locking nut is disassembled, the position of the connection bolt 34 in the connection notch 33 is adjusted in correspondence with the replacement of the connection hole 31 of the anti-slip ring 5, and the connection and locking are reconnected. This embodiment can meet the positioning and clamping of the anti-slip ring 5 workpieces of different specifications and sizes by replacing the corresponding washers, so that the utility model has universality. It eliminates the trouble of separately making a set of positioning tooling for different anti-slip ring 5 products, reduces the tooling production cost, and facilitates the tooling management at the work site.

[0032] Furthermore, the connecting hole 31 is a semi-open structure, so that the connecting bolt 34 can be hung from the side, eliminating the trouble of completely disassembling the connecting bolt 34 and the locking nut.

[0033] Furthermore, a avoidance hole is provided on the backing ring 3 corresponding to the hole position to be processed of the anti-slip ring 5 workpiece, and the diameter of the avoidance hole is larger than the hole position to be processed of the anti-slip ring 5. During the drilling operation of the anti-slip ring 5 workpiece, the drill bit can penetrate the anti-slip ring 5 workpiece and smoothly enter the avoidance hole, so as to facilitate the drilling operation of the anti-slip ring 5 workpiece and improve the operation efficiency and drilling quality.

[0034] Furthermore, a positioning pin 12 is provided on the support block 2 corresponding to the positioning hole 35 of the gasket 3, and the positioning pin 12 cooperates with the positioning hole 35 pin hole to position the radial angle of the workpiece of the anti-slip ring 5. When in use, the positioning pin 12 is inserted into the positioning hole 35 of the gasket to ensure the precise positioning of the gasket radial angle and ensure the processing accuracy.

[0035] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be regarded as belonging to the protection of the present invention.
