Abstract

The invention discloses a sleeve part machining clamp which comprises a rotary mandrel, wherein the rotary mandrel comprises a sleeve shaft part, and a blocking part and a thread part which are positioned at two ends of the sleeve shaft part, the outer diameter of the blocking part is larger than that of the sleeve shaft part, a locking nut is assembled on the thread part, a part to be machined is sleeved on the sleeve shaft part, one end of the part is pressed by the locking nut, the other end of the part is attached to the blocking part, rapid clamping is formed, and the end face of the blocking part is used as a machining reference surface. Above-mentioned cover type parts machining anchor clamps have designed simple spacing frock for the part only needs the cover to rotate the dabber, and screws through lock nut, can accomplish reliable location, thereby guarantees the machining precision, has effectively improved machining efficiency.

Description

Sleeve part machining clamp

Technical Field

The invention relates to the technical field of clamps, in particular to a sleeve part machining clamp.

Background

For the outer surface forming processing of some small-sized sleeve parts 1 ', the outer surface is generally clamped by a three-jaw chuck 2', the outer circle and the end surface of the part 1 'are subjected to surface making and alignment, and then the processing can be carried out by a grinding wheel 3' and the like so as to ensure the processing precision, as shown in fig. 2. The processing mode has the disadvantages that the operation is complex, the processing efficiency is low and the batch processing requirement cannot be met because the table is required to be re-marked and positioned after the clamping is carried out in each processing period.

Disclosure of Invention

Based on the problems, the invention aims to provide a sleeve part machining clamp, which is used for simply and reliably clamping a sleeve part, improving machining efficiency and ensuring machining precision.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a cover type parts machining anchor clamps, its includes rotatory dabber, rotatory dabber includes sleeve axial region and the fender portion and the screw thread portion that are located sleeve axial region both ends, and the external diameter of fender portion is greater than the external diameter of sleeve axial region, is equipped with lock nut on the screw thread portion, treats that the processing part cover is located on the sleeve axial region, and the one end of part is compressed tightly by lock nut, and the other end pastes and leans on fender portion, forms quick clamping to regard the terminal surface of fender portion as the processing reference surface.

Particularly, the rotating mandrel is sleeved with a gasket for preventing the locking nut from being in direct contact with a part.

In particular, the outer diameter of the threaded portion is smaller than the outer diameter of the sleeve portion.

In particular, the sleeve shaft portion is externally provided with a replaceable adjustment sleeve to adapt to the inner diameter dimension of the part.

In conclusion, the sleeve part machining clamp has the advantages that a simple limiting tool is designed, so that a part can be reliably positioned only by sleeving the part on the rotating mandrel and screwing the part through the locking nut, machining precision is guaranteed, and machining efficiency is effectively improved.

FIG. 1 is a schematic structural diagram of a fixture for machining sleeve parts according to an embodiment of the present invention;

fig. 2 is a schematic structural diagram of a conventional sleeve part machining fixture.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar parts throughout or parts having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediary, a connection between two elements, or an interaction between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the description of the present invention, unless otherwise expressly specified or limited, the first feature "on" or "under" the second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but with another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1, the preferred embodiment provides a sleeve part processing fixture, which includes a rotating mandrel, the rotating mandrel includes a sleeve shaft portion 2, and a stop portion 3 and a threaded portion 4 located at two ends of the sleeve shaft portion 2, the stop portion 3 has an outer diameter larger than that of the sleeve shaft portion 2, and the threaded portion 4 has an outer diameter smaller than that of the sleeve shaft portion 2.

The threaded part 4 is provided with a locking nut 5, and the rotating mandrel is sleeved with a gasket 6 for avoiding the direct contact between the locking nut 5 and the part 1.

In particular, the sleeve shaft part 2 is provided externally with an exchangeable adjustment sleeve 7 to adapt the inner diameter dimension of the part 1.

The part 1 to be processed is sleeved on the sleeve shaft part 2, one end of the part 1 is tightly pressed by the locking nut 5, the other end of the part 1 is attached to the blocking part 3, rapid clamping is formed, the end face of the blocking part 3 serves as a processing reference face, and therefore the positioning operation difficulty is reduced, and processing is facilitated.

In conclusion, the simple limiting tool is designed in the sleeve part machining clamp, so that the parts only need to be sleeved on the rotating mandrel and are screwed through the locking nut, reliable positioning can be completed, machining precision is guaranteed, and machining efficiency is effectively improved.

The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but is capable of various modifications and changes without departing from the spirit and scope of the invention, which are intended to be within the scope of the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
