Abstract
The utility model relates to a hydraulic clamp for a numerically controlled lathe. The hydraulic clamp for the numerically controlled lathe is characterized by consisting of a body, a pull rod, an expansion sleeve and a positioning sleeve; the expansion sleeve and the positioning sleeve are both fixedly arranged on the body; and the pull rod is sleeved in the expansion sleeve. The hydraulic clamp for the numerically controlled lathe has a scientific and reasonable structural design and small errors, and is easy to manufacture, convenient to operate, and high in stability, workpiece replacement speed, precision and novelty.
Description
Technical field
The utility model belongs to the machining apparatus field, particularly a kind of numerically controlled lathe hydraulic chucks.
Background technology
Jig also is chuck, is the vitals on the lathe, in order to fixation workpiece so that process.Jig on the numerically controlled lathe mostly was jack catchs type in the past, and fluid pressure type is also arranged, and above-mentioned jig is few owing to the pawl number, and structure is unreasonable, all has complex structure, and manufacture difficulty is large, and error is large, and precision is low, troublesome poeration, and it is slow to change work speed, the deficiencies such as poor work stability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of pawl number is many, error is little, precision is high, changes that work speed is fast, the numerically controlled lathe hydraulic chucks of good operating stability.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of numerically controlled lathe hydraulic chucks is characterized in that: be comprised of body, pull bar, ringfeder, positioning sleeve, ringfeder, positioning sleeve all are installed on the body, and drag link sleeve is loaded in the ringfeder.
And described ringfeder is that a profile is I-shaped hollow circular cylinder, and its underpart is the ringfeder chassis, and top is the harmomegathus pawl, and ringfeder chassis, harmomegathus pawl are made as one.
And described harmomegathus pawl is 6, is distributed on the ringfeder chassis, is shaped with the harmomegathus seam between the adjacent harmomegathus pawl, and harmomegathus pawl upper inner is shaped with tapered slope, and tapered slope is enclosed conical cavity.
And, described pull bar, its top is conical head, and the centre is cylindrical drag link body, and the bottom is drawing head, and conical head, cylindrical drag link body, drawing head are made as one.
Advantage of the present utility model and beneficial effect are:
1. this numerically controlled lathe hydraulic chucks simple structure is made easily;
2. this numerically controlled lathe hydraulic chucks harmomegathus pawl is many, good operating stability;
3. this numerically controlled lathe hydraulic chucks is easy and simple to handle, and it is fast to change work speed, and every order of classes or grades at school is brought up to about 1000 by producing about 300;
4. this numerically controlled lathe hydraulic chucks is internal expansion type, and error is little, and precision is high, and product percent of pass rises to more than 95% by 75%;
5. this numerically controlled lathe hydraulic chucks scientific structure design is reasonable, have make easy, easy and simple to handle, good stability, the replacing work speed is fast, error is little, the precision advantages of higher, is a kind of numerically controlled lathe hydraulic chucks with higher innovation.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of numerically controlled lathe hydraulic chucks is comprised of body 4, pull bar 1, ringfeder 2, positioning sleeve 3, and ringfeder, positioning sleeve all are installed on the body, and drag link sleeve is loaded in the ringfeder.
Ringfeder is that a profile is I-shaped hollow circular cylinder, and its underpart is ringfeder chassis 12, and top is harmomegathus pawl 8, and ringfeder chassis, harmomegathus pawl are made as one.
The harmomegathus pawl is 6, is distributed on the ringfeder chassis, is shaped with harmomegathus seam 11 between the adjacent harmomegathus pawl, and harmomegathus pawl upper inner is shaped with tapered slope 9, and tapered slope is enclosed conical cavity 10.
Pull bar, its top are conical head 5, and the centre is cylindrical drag link body 6, and the bottom is drawing head 7, and conical head, cylindrical drag link body, drawing head are made as one, and conical head is assemblied in the conical cavity of ringfeder.
Operation principle of the present utility model is:
The utility model is assembled on the jig seat on the numerically controlled lathe, drawing head is connected with hydraulic system, workpiece is sleeved on the positioning sleeve, the primer fluid pressure device, hydraulic means pulling drawing head moves backward, driving cylindrical drag link body and conical head moves backward, conical head moves backward and forces the harmomegathus pawl to expand outwardly, thus the workpiece that will be sleeved on the fixed cover fix firmly since have 6 fixing, therefore can not produce slip, fixation; After a workpiece completion of processing, the temporary close hydraulic selector, hydraulic system is removed the pulling force to pull bar, and the harmomegathus pawl of ringfeder restores to the original state automatically, and pull bar sets back, i.e. replaceable workpiece.
