Abstract
The invention discloses an internal-supporting positioning type limiting clamp device, wherein positioning tables (10) are arranged on two sides of a positioning guide seat (1), positioning heads (4) are arranged on the positioning tables through positioning pins (5), and one ends of the positioning heads are connected with positioning bolts (9); a pull rod (6) is inserted and arranged in the positioning guide seat and between the positioning platforms at the two sides of the positioning guide seat through a pull rod spring (2), a compression bolt (7) is sleeved in the pull rod, and the two sides of the pull rod are in a taper structure (11) and are adjacent to the positioning head. And the positioning bolt is arranged on the positioning bolt fixing block through a positioning spring. The invention ensures that the pull rod drives the positioning head to be propped open to be in contact with and fixed with the positioning surface required by the workpiece, thereby achieving the positioning and limiting effects, ensuring that the workpiece has accurate positioning and stable processing quality in the processing process, avoiding the occurrence of excessive unnecessary waste and unstable quality hidden troubles, and playing the roles of obviously improving the product quality and the efficiency.
Description
Technical Field
The invention relates to a clamp device for clamping a workpiece.
Background
In the manufacturing and processing industry of aluminum alloy parts of existing fuel automobile engines and various new energy automobile engines, parts such as cylinder bodies, engine bases, shells and the like generally need to be machined, for example, the cylinder bodies are complex in structure and have more internal machining procedures. According to the particularity of this kind of product structure and to the machined surface and the dimensional requirement of product higher, it is spacing that general customer requires to use the cylinder liner hole, send a kind stage customer demand earlier stage less, have the possibility of renewing the product structure at any time, if use normal hydraulic pressure volume production anchor clamps processing, have the too big and preparation cycle overlength scheduling problem of input cost earlier stage, still have the difficult and not accurate difficult problem of location.
Disclosure of Invention
The invention aims to overcome the defects, and provides the internal support positioning type limiting clamp device which is simple and convenient to operate and accurate in positioning and limiting. The positioning device can ensure that a workpiece is positioned accurately and the machining quality is stable in the machining process, and avoids the hidden danger of unnecessary waste and unstable quality.
The purpose of the invention is realized by the following technical scheme: the inner supporting positioning type limiting clamp device comprises a positioning guide seat, positioning tables are arranged on two sides of the positioning guide seat, positioning heads are arranged on the positioning tables through positioning pins, and one ends of the positioning heads are connected with positioning bolts; and a pull rod is inserted and arranged in the positioning guide seat and between the positioning platforms at the two sides of the positioning guide seat through a pull rod spring, a compression bolt is sleeved in the pull rod, and the two sides of the pull rod are in a taper structure and are adjacent to the positioning head.
After the structure is adopted, after a workpiece is clamped, the pull rod drives the positioning head, the positioning head is propped open to be in contact with and fixed with a positioning surface required by the workpiece, and a positioning limiting effect is achieved. The invention can be completely used in the inner hole positioning and limiting clamp devices of all similar workpieces, and the positioning, limiting and clamping of the structure is simple, quick and flexible, and has very wide applicability.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic view of the mounting structure of the present invention (with the workpiece in a position-limiting state).
Fig. 2 is a schematic structural view of the positioning head and the workpiece in a released state in fig. 1.
Detailed Description
Referring to fig. 1 and 2, the internal-supporting positioning type limiting fixture device comprises a positioning guide seat 1, positioning tables 10 are arranged on two sides of the positioning guide seat 1, positioning heads 4 are arranged on the positioning tables 10 through positioning pins 5, one ends (close to two sides of the positioning guide seat) of the positioning heads 4 are connected with positioning bolts 9 (the positioning bolts 9 are arranged on a positioning bolt fixing block 3 through positioning springs 8, and the positioning bolt fixing block 3 is connected with two side edges of the positioning guide seat 1); a pull rod 6 is inserted and installed in the positioning guide seat 1 and between the positioning platforms at the two sides of the positioning guide seat through a pull rod spring 2, a compression bolt 7 is sleeved in the pull rod 6, and the two sides of the pull rod 6 are in a taper structure 11 and are adjacent to the positioning head 4.
The positioning guide seat 1 of the internal-supporting positioning type limiting clamp device is arranged in a clamp bottom plate 13 of a special clamp, a positioning head 4, a pull rod 6, a compression bolt 7 and the like are placed in a clamping inner hole of a workpiece 12 (cylinder body product), and the other end (two sides far away from the positioning guide seat) of the positioning head 4 faces the inner wall of the clamping inner hole of the workpiece.
The working principle of the invention is as follows: before the workpiece is clamped, the compression bolt 7 is loosened, and the pull rod 6 is pulled to enable the positioning head 4 to be in a loosened state, as shown in fig. 2. After the workpiece 12 is clamped by a special clamp, the pull rod 6 is driven to press downwards (the pull rod spring 2 is compressed by leftward movement as shown in fig. 1) through the locking of the compression bolt 7, and the positioning head 4 is stretched to prop against the clamping inner hole of the workpiece 12 by taking the positioning pin 5 as a fulcrum through the protruding parts of the pull rod with the two sides of the tapered structure, so that the effective and accurate positioning and limiting effects are achieved. And the positioning bolt 9 is screwed tightly to ensure that the positioning and the limiting of the positioning head are firmer. The pull rod 6 drives the positioning head 4 to play a role in fixing the positioning head to a workpiece limiting surface (a position needing to be positioned and limited). Therefore, the production efficiency, the processing quality and the like of workpiece processing are improved, and the effects of obviously improving the product quality and reducing the cost are achieved.
The workpiece is fixed by pressing all special clamps to press the pressing plates, and after the workpiece is clamped, the torque wrench is operated to twist the pressing bolt, so that the manual positioning and limiting function can be achieved, and the invention can achieve the effect of accurate positioning by manual operation. And the structure is reliable, the maintenance and the disassembly are convenient, and the universality is very wide.
