Description

Technical Field

[0001] The utility model relates to the field of chuck rings, in particular to a chuck ring for fastening connection. Background Art

[0002] The chuck ring is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that clamps and positions the workpiece by radial movement of the movable jaws evenly distributed on the chuck body. The chuck generally consists of three parts: the chuck body, the movable jaws and the jaw drive mechanism.

[0003] According to a chuck disclosed on the patent website (authorization announcement number: CN 205218102 U), "a chuck includes a disc body, a claw body located on the upper end surface of the disc body, a two-way mechanism for guiding the claw body to move in both directions, and a pressure plate for fixing the claw body and located above the two-way mechanism."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the device uses a pressure cylinder to push the claw body to move and clamp the workpiece through the claw, but the claw body is fixed above the disc body, and the shape of the claw body is fixed, it can only fix workpieces of specific shapes. When an irregular workpiece appears, the flat claw body will have a smaller contact area with the workpiece, and the workpiece cannot be effectively fixed, resulting in loosening of the workpiece during processing, affecting the clamping size. Therefore, it is necessary to improve a chuck ring with a fastened connection to solve the above problem. Utility Model Content

[0006] In order to overcome the problem that the claw body is fixedly connected to the disc body and cannot be replaced, and cannot stably clamp special-shaped workpieces.

[0007] The technical solution of the present utility model is as follows: A chuck ring with firm connection, comprising a fixed cylinder, a guide disk, a housing, a fixed disk, a positioning cylinder, an internal hexagonal rotating block, a rotating rod, a first bevel gear and a second bevel gear; further comprising a positioning component and an installation component; the positioning component is arranged inside the fixed cylinder and the guide disk, and the installation component is arranged inside the positioning component; the positioning component includes a groove block, the groove block is slidably connected inside the guide disk, a slide rod is slidably connected inside the groove block, the slide rod is limited by the groove block to facilitate the replacement of the clamping block, and a clamping block is fixedly connected to the inner side of the slide rod; the installation component includes a clamping rod, the clamping rod is slidably connected inside the groove block, a connection disk is fixedly connected to the outer side of the clamping rod, a spring is fixedly connected between the connection disk and the groove block, and a pull ring is fixedly connected to the outer side of the connection disk; the left side of the guide disk is fixedly connected with a housing, a fixed disk is fixedly connected between the housing and the fixed cylinder, a positioning cylinder is fixedly connected to the right side of the fixed disk, the internal hexagonal rotating block is rotatably connected inside the housing, a rotating rod is fixedly connected to the inner side of the internal hexagonal rotating block, the rotating rod is rotatably connected inside the positioning cylinder, a first bevel gear is fixedly connected to the outside of the rotating rod, a second bevel gear is meshed with the outside of the first bevel gear, rotating one first bevel gear can drive the second bevel gear, so that the three first bevel gears rotate synchronously, and the second bevel gear is fixedly connected to the left side of the scroll disk.

[0008] Preferably, the first bevel gear rotates the scroll disk, so that the three groove blocks drive the clamping blocks to clamp the workpiece synchronously. The clamping rod can be pulled out of the clamping hole of the slide rod, and then the clamping block can be replaced. Replace the clamping block corresponding to the shape of the workpiece, so that the contact surface with the workpiece is larger, and the position of the workpiece can be firmly fixed.

[0009] As a preference, a meshing plate is fixedly connected to the left side of the groove block. The meshing plate is fixedly connected to the left side of the groove block, and a scroll disk is meshed with the left side of the meshing plate. By rotating the scroll disk, the three meshing plates can be driven to slide synchronously, so as to symmetrically clamp the workpiece.

[0010] As a preference, a chute is provided at the corresponding position of the guide disk for the groove block, and the groove block slides inside the chute. The chute limits the groove block and guides the groove block to prevent the groove block from sliding through the scroll disk and being separated.

[0011] As a preference, a clamping hole is provided at the corresponding position of the slide rod for the clamping rod, and the clamping rod is clamped inside the clamping hole. By inserting the clamping rod into the clamping hole, the position of the slide rod can be positioned to prevent the slide rod from being separated, which is convenient for replacing the slide rod.

[0012] As a preference, three first bevel gears are provided, and the second bevel gear meshes with the three first bevel gears. When one of the first bevel gears drives the second bevel gear, the second bevel gear can make the other two first bevel gears rotate synchronously.

[0013] Preferably, a limiting hole is formed at a corresponding position of the positioning cylinder on the rotating rod, and the rotating rod is rotatably connected inside the limiting hole. The rotating rod is positioned through the limiting hole to enable stable rotation of the rotating rod, and thus the first bevel gear can be driven by the rotating rod.

[0014] Preferably, three hexagon socket rotating blocks are provided, and the three hexagon socket rotating blocks are symmetrically and rotatably connected inside the housing. Due to the symmetrical distribution of the three hexagon socket rotating blocks, it is convenient for workers to vibrate the hexagon socket rotating blocks during use.

[0015] Advantages of the present utility model:

[0016] 1. Compared with the prior art, the clamping block can be replaced. According to the size and shape of the workpiece, the clamping block can be correspondingly replaced, so that the shape of the clamping block corresponds to the shape of the workpiece, thereby increasing the friction between the clamping block and the workpiece and enabling the clamping block to firmly clamp the workpiece stably, with a wider application range.

[0017] 2. The spring can position the position of the clamping rod, prevent the clamping rod from automatically disengaging from the clamping hole of the sliding rod, and directly pulling the pull ring can disengage the clamping rod. The spring can make the clamping rod automatically reset, stably fix the position of the sliding rod, and prevent loosening. Description of the drawings
