TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts processing, in particular to a special adjustable and compact pressing clamp for milling grooves of automobile keys. BACKGROUND
[0002] In the automobile manufacturing process, the automobile key is an indispensable part. In order to meet the functional requirements, it is usually necessary to mill a light-blocking groove in the inner cavity of the automobile key. During the milling process, the automobile key needs to be precisely positioned and firmly clamped by the clamp to ensure the machining precision and quality.
[0003] However, the existing automobile key milling clamp has many shortcomings. On the one hand, some clamps are not precise enough in positioning and cannot be adjusted, which may cause displacement of the automobile key during the machining process, affecting the precision of milling and thus reducing the product quality. On the other hand, some clamps are designed unreasonably, with large width and height, occupying a large space and being not conducive to assembly and operation, wasting space and materials.
[0004] Therefore, the present scheme proposes a special clamp for milling grooves of automobile keys, which can stably clamp, adjust the pressing position, and is small, compact, and easy to operate. SUMMARY
[0005] In view of the problems existing in the prior art, the utility model provides a special adjustable and compact pressing clamp for milling grooves of automobile keys, comprising:

[0007] A pressing plate is arranged above the placing groove for pressing the workpiece. The pressing plate is provided with a milling opening for the milling equipment to enter the milling groove. The bottom surface of the pressing plate is provided with a limiting groove matching the shape of the workpiece;
[0008] A pressing handle is detachably mounted on the base through a support. The pressing handle is arranged on the left side of the pressing plate. The pressing handle comprises a waist-shaped mounting groove, a threaded column mounted in the waist-shaped mounting groove, a rubber pressure head fixedly installed at the bottom of the threaded column, the rubber pressure head being arranged above the pressing plate and used for pressing the base and the pressing plate, the threaded column being fixedly installed in the waist-shaped mounting groove through an upper nut and a lower nut, and a gasket being arranged between the waist-shaped mounting groove and the upper and lower nuts, the gasket being a U-shaped groove structure to facilitate the sliding adjustment of the installation position of the threaded column in the waist-shaped mounting groove;
[0009] The workpiece is integrally formed with two vertical plates at the middle position of the inner cavity. The middle position of the two vertical plates is provided with a light-blocking groove formed by milling. The periphery of the inner cavity of the workpiece is integrally formed with a protrusion.
[0010] As a preferred scheme of the utility model, the vertical plate is placed perpendicularly to the milling groove opening and extends upward into the milling groove opening, which can reduce the width and height of the clamp as a whole, and make the clamp smaller and more compact.
[0011] As a preferred scheme of the utility model, the pressing plate is provided with a circular groove, and the circular groove is arranged correspondingly to the rubber pressing head, which is in the shape of an inverted circular truncated cone.
[0012] As a preferred scheme of the utility model, the base and the pressing plate are provided with threaded holes in the side surfaces, and the threaded holes are provided with hinges through screws, which are used for turning the pressing plate for assembly.
[0013] As a preferred scheme of the utility model, the placing grooves are arranged in two rows, and each row has three placing grooves.
[0014] As a preferred scheme of the utility model, the limiting grooves are pasted with buffer pads, which are used for protecting the workpiece.
[0015] Due to the above technical scheme, the utility model has the following beneficial effects:
[0016] The limiting groove matched with the shape of the workpiece can accurately position the workpiece, ensure that the workpiece will not displace during the milling groove process, improve the precision of the milling groove, and provide stable pressing force through the cooperation of the rubber pressing head of the pressing handle and the circular groove on the pressing plate, so as to ensure that the workpiece will not loosen during the milling groove process and ensure the continuity and stability of the processing. The threaded column can be slidably adjusted in the waist-shaped mounting groove, so that the workpiece can be pressed flexibly. The buffer pad pasted in the limiting groove can effectively protect the surface of the workpiece and avoid damage during clamping and processing. The assembly of the workpiece reduces the width and height of the clamp as a whole, so that the clamp is more compact and saves space, which is convenient for installation and operation on the processing equipment.
