Therefore, how to effectively improve the reliability of the clamping device on the lathe is an urgent problem to be solved in the field.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problem existing in the clamping jaw on the existing lathe, the utility model aims to provide an elongated clamping jaw. The clamping jaw lengthening part is additionally arranged, so that the stress area can be increased, and the clamping force is improved.
In order to achieve the above object, the present invention provides an elongated jaw, which is composed of two parts: the clamping jaw comprises a clamping jaw body and a clamping jaw lengthening part, wherein the clamping jaw body is connected with the lengthening part, and the length ratio of the clamping jaw body to the lengthening part is 1: 4.
Furthermore, the middle part of the outer surface of the jaw lengthening part is provided with a fixing hole, and two sides of the jaw lengthening part are provided with adjusting teeth.
Furthermore, the working surface of the jaw lengthening part is an arc surface.
Furthermore, the working surface of the jaw lengthening part is provided with a friction layer.
Furthermore, the working surface of the jaw body is an arc surface.
Furthermore, the working surface of the claw body is provided with a friction layer.
The utility model relates to an add elongated jack catch, when its concrete application, through addding jack catch extension, increase area of contact makes the lifting surface area grow, effectual improvement and spare part between the clamp force, effectively solve the problem that prior art exists.
Moreover, the lengthened clamping jaw is simple in integral composition structure, low in cost and high in practicability.
Drawings
The invention is further described with reference to the following drawings and detailed description.
FIG. 1 is a side view of an elongated pawl of the present example;
FIG. 2 is a top plan view of the elongated pawl of the present example;
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1 and 2, there are shown schematic views of the elongated jaws given in this example;
as can be seen from the figure, the lengthened claw is composed of two parts: a jaw body 10 and a jaw extension 20. The surface of the jaw extension 20 is provided with 3 fixing holes 30 and 2 rows of adjusting teeth, the two rows of adjusting teeth are respectively a first adjusting tooth 40 and a second adjusting tooth 50, and the shapes and the sizes of the two rows of adjusting teeth are the same.
The jaw body 10 and the jaw extension part 20 are integrally formed, and the overall structure is an L-shaped structure. The L-shaped structure has a right-angle area, so that the edge of the workpiece can be well embedded inside.
In concrete implementation, 3 fixing holes 30 are uniformly formed in the middle of the outer surface of the jaw extension part 20, and the fixing holes 30 are not limited in shape and size and are used for being connected with corresponding guide assemblies. And the first adjusting tooth 40 and the second adjusting tooth 50 are symmetrically arranged at two sides of the fixed hole 30 and are used for matching with the adjusting component.
In the scheme, the length ratio of the clamping jaw body 10 to the clamping jaw lengthening part 20 is 1:4, so that the contact area can be effectively increased, the stress area is enlarged, and the clamping force between the clamping jaw body and a part is effectively improved.
In order to further improve the clamping effect, the friction layer is arranged on the inner side surface 11 (the side surface facing the right-angle area) of the claw body 10 in the present embodiment, so as to improve the binding force with the workpiece and ensure the clamping effect.
The friction layer may be formed by an array of friction lobes.
Alternatively, in this embodiment, the inner side surface 11 (the side surface facing the right-angle area) of the pawl body 10 is a circular arc surface, and corrugated friction ridges are symmetrically distributed on both sides of the circular arc surface.
In order to further improve the clamping effect, the friction layer is provided on the inner side surface 21 (the side facing the right-angle area) of the jaw extension portion 20 in this example, so as to improve the bonding force with the workpiece and ensure the clamping effect.
The friction layer may be formed by an array of friction lobes.
Alternatively, in the present example, the inner side surface 21 (the side surface facing the right-angled region) of the pawl extension portion 20 is a circular arc surface, and the entire surface thereof is provided with a corrugated friction ridge.
Because this elongated jack catch needs long-time and work piece contact, in order to improve the durability of elongated jack catch, when according to the in-service use, can be with the one deck wearing layer of whole elongated jack catch surface coating to improve the durability of whole elongated jack catch.
The film thickness of the wear-resistant layer on the inner side surface 21 of the claw lengthening part 20 and the inner side surface 11 of the claw body 10 is 1.5 times to 2 times of the film thickness on other side surfaces.
In addition, a handle structure can be arranged on the outer side surface of the jaw body 10 according to requirements, so that the lengthened jaw can be conveniently assembled and disassembled. Preferably, the handle structure can adopt a concave slot hole structure, so that the actual use of the claw body 10 is not influenced, and the convenience of the assembling and disassembling operation can be improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
