Abstract
The utility model relates to the technical field of tool fixtures, in particular to a three-jaw chuck with a backstop. The three-jaw chuck can resist a workpiece while clamping the workpiece, so that the workpiece is prevented from moving in machining, and the backstop can prevent iron chips generated in the turning process from being wound in a spindle hole of a machine tool. The technical scheme includes that the three-jaw chuck comprises a three-jaw chuck body, a backstop is arranged at the center of the three-jaw chuck body, an adjusting screw is arranged at the center of the backstop, and further the backstop comprises a backstop outer ring and a backstop inner ring, and the backstop inner ring is sleeved in the backstop outer ring.
Description
Technical Field
The utility model relates to the technical field of tool fixtures, in particular to a three-jaw chuck with a backstop.
Background
When a workpiece is clamped by the three jaws and bar-type workpieces are roughly machined, the three-jaw clamping force is not large enough under the conditions of over-adhesion of workpiece materials, over-large drilling diameter of the workpiece, over-large drill bit and the like, the workpiece retreats into the chuck during machining, the actual size of the part cannot be machined and the part needs to be machined again, and scrap iron generated in the turning process can drill into a spindle of a machine tool along with the rotation of the workpiece, so that the machining process is inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a three-jaw chuck with a backstop, which can be used for propping against a workpiece while clamping the workpiece, so that the workpiece is prevented from moving in the machining process, and the backstop can also be used for preventing scrap iron generated in the turning process from being wound in a main shaft hole of a machine tool.
In order to solve the problems in the prior art, the technical scheme of the utility model is as follows: the utility model provides a three-jaw chuck with backstop ware, includes three-jaw chuck body, its characterized in that: the center of the body of the three-jaw chuck is provided with a backstop, and the center of the backstop is provided with an adjusting screw rod.
Further, the retaining device comprises a retaining device outer ring and a retaining device inner ring, and the retaining device inner ring is sleeved in the retaining device outer ring.
Compared with the prior art, the utility model has the following advantages:
1. according to the structure, the part is propped by the retaining device outer ring 2, the retaining device inner ring 3 and the adjusting screw rod 4, so that the workpiece cannot retreat any more when a large hole is drilled in deep cutting and large feeding, and the problem of insufficient machining of the actual size cannot occur.
2. According to the utility model, a large amount of scrap iron is effectively prevented from being discharged backwards along the inner hole of the main shaft through the adjusting screw, so that each workpiece is stopped when being processed, the scrap iron accumulated in the main shaft is cleaned, and a large amount of time cost is saved.
3. According to the utility model, the clamping length of the workpiece is locked by determining the size of the dimension H, so that the clamping length of the workpiece is not changed, the clamping alignment time is shortened, and the workpiece is rapidly clamped.
Drawings
FIG. 1 is a schematic structural view of the present invention;
description of reference numerals: 1. the three-jaw chuck comprises a three-jaw chuck diagram, 2, a backstop outer ring, 3, a backstop inner ring, 4, an adjusting screw rod and 5, and a demonstration workpiece.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The embodiment provides a three-jaw chuck with backstop, including three-jaw chuck body 1, three-jaw chuck's body 1's center be provided with the backstop, the backstop includes backstop outer loop 2 and backstop inner ring 3, 3 covers of backstop inner ring are provided with adjusting screw 4 in the backstop outer loop 2, the inner ring center of backstop.
The working process of the utility model is as follows: when the three-jaw clamp the workpiece, the workpiece is prevented from moving in the machining process by the retaining device outer ring 2, the retaining device inner ring 3 and the adjusting screw rod 4 to support the part; the size of H can be adjusted by adjusting the screw rod 4, so that the batch production of workpieces is facilitated, and the alignment process is reduced; whole center stopping ware can effectively block iron fillings, reduces the influence that iron fillings caused to processing.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
