Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to a riveting mold for a tapered roller bearing. Background Art

[0002] The tapered roller bearing riveting die is a die specially used for riveting tapered roller bearings. The die is mainly composed of a die body and a gasket. The die body is provided with a riveting cavity for accommodating and fixing the tapered roller bearing to be riveted. The gasket is arranged above the die body and can move up and down relative to the die body. The gasket is connected to the die body through a lifting guide device to ensure the stability and accuracy of the gasket during the lifting process.

[0003] The mold is installed on the mounting seat, and the mounting seat is installed on the sliders of two cylinder slide rails. After the cylinder works, it drives the mounting seat to move back and forth to ensure the safety of the staff during loading and unloading.

[0004] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: since riveting is performed by pressing with hydraulic equipment, the force exerted by the hydraulic equipment not only acts on the bearing component, but also on the mounting seat during pressing, and is then transmitted to the slider and the guide rail through the mounting seat. Frequent pressing over a long period of time can easily lead to deformation of the slide rail, resulting in inaccurate movement of the slider, jamming during movement, and defective products in the riveting process of the bearing. Utility Model Content

[0005] The main purpose of the utility model is to provide a tapered roller bearing riveting die, which can effectively solve the problems in the background technology.

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

[0007] A tapered roller bearing riveting die comprises a workbench and a guide groove, wherein cylinder guide rails are provided at both ends of the workbench, guide rail sliders are slidably connected to the cylinder guide rails, the tops of the guide rail sliders are connected to fixed seats by bolts, block grooves are drilled at the front and rear ends of the fixed seat, traction blocks are inserted inside the guide grooves, a moving groove is drilled at one end of the block grooves, bolts are inserted through the inside of the moving grooves, a plurality of screw grooves are drilled at the inner side walls of the block grooves, a mounting seat is provided between the fixed seats, connecting parts are fixed at the two ends of the bottom of the mounting seat, a sliding groove is drilled at the top of the workbench at the mounting seat position, a sliding block is slidably connected inside the sliding groove, a plurality of tooth grooves are provided at both ends of the front and rear side walls of the mounting seat, and a plurality of convex teeth are provided on the side walls of the traction block at the tooth groove position.

[0008] Preferably, the protruding teeth are respectively meshed and connected with tooth grooves that match their positions.

[0009] Preferably, one end of the bolt member passes through the movable groove and is inserted into a screw groove of matching position and is threadedly connected thereto.

[0010] Preferably, a guide block is fixed on the top of the traction block, and a guide groove is drilled at the inner top of the fixing seat located at the block groove, and the guide blocks are respectively inserted into the guide grooves and slidably connected thereto.

[0011] Preferably, the length of the guide block matches the length of the traction block.

[0012] Preferably, the connecting members are detachably connected to the sliding blocks via bolts.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The mounting seat is connected to the sliding block through a connecting piece, so that the mounting seat can slide non-powerfully in the sliding groove through the sliding block. The connection between the fixed seat and the guide rail slider enables the guide rail slider to drive the fixed seat to slide dynamically on the cylinder guide rail, and the fixed seat can engage with the tooth groove on the side wall of the mounting seat through the convex teeth on the side wall of the traction block, and the fixed seat can drive the tooth groove to move together when moving. When the upper hydraulic equipment descends and applies force to the mounting seat, the force will be transmitted to the sliding block and the workbench, and will not act on the cylinder guide rail and the guide rail slider, which effectively protects the cylinder guide rail and the guide rail slider. Even if the sliding block is damaged, the replacement cost is relatively low.

[0015] 2. When the size of the mounting seat changes due to the size of the bearing, the fixed seat can be directly replaced. After the fixed seat is replaced, the traction block is inserted into the block groove, and then the bolt penetrates the movable groove and is inserted into the screw groove at the matching position and threadedly connected, so that the traction block can be limited. The traction block can contact the tooth grooves at different positions of the side wall of the mounting seat through the convex teeth, ensuring that the mounting seat can be driven to move after the size is changed, while also reducing the parts required for replacing the mold.

[0023] Specifically, the protruding teeth 66 are respectively engaged with the tooth grooves 3 at matching positions, so that the traction mounting seat 2 is more stable when moving.

[0024] Specifically, one end of the bolt 68 passes through the movable groove 67 and is inserted into the screw groove 63 of matching position and is threadedly connected thereto, so as to limit the traction block 64 .

[0025] Specifically, a guide block 65 is fixed on the top of the traction block 64, and a guide groove 62 is drilled at the inner top of the fixed seat 6 located at the block groove 61. The guide blocks 65 are respectively inserted into the guide grooves 62 and slidably connected thereto.
