Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "front", "back", "left", "right", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-6, the adjustable chip holder has a base 2, four corners of the lower plane of the base are provided with support legs 3, a nut 4 is provided in the middle of the lower plane of the base 2, the mounting manner is welding, and the end surface of the nut and the lower plane of the base need to maintain a high verticality in order to ensure smooth operation. The penetrating U type recess in face about the base left end processing, the lower plane welding of grip block 1 two projections of band-pass hole, wherein first arch 7 is located the grip block leftmost side, and second arch 6 is located first protruding right side and sets for the distance apart, and screw rod 8 runs through two bellied through-holes and 4 screw-thread fit of nut. The through holes of the two bulges and the nuts need to keep higher coaxiality, so that the smooth operation of the screw can be ensured without clamping stagnation. The straightness of the screw needs to be controlled within 0.03 mm. A compression spring 9 is arranged between the first bulge and the second bulge and is sleeved outside the screw rod. Two clamping rings are sleeved on the screw rod 8, the first clamping ring 10 is located between the first protrusion 7 and the compression spring 9, and the second clamping ring 5 is located on the left side of the second protrusion 6. The compression spring plays a buffering role, so that the chip is prevented from being damaged by extrusion, and the probability of damaged parts is reduced.

A plurality of mutually matched clamping grooves are respectively arranged on the left side of the base 2 and the right side of the clamping plate, and a clamping space formed by matching the clamping grooves on the base and the clamping grooves on the clamping plate is in a diamond shape. The shape and the depth of each clamping groove are different. The clamping groove with large overall dimension is deep, and the clamping groove with small overall dimension is shallow.

The base 2 is provided with guide grooves 11 on both sides of the rod, the length direction of the guide grooves needs to keep high straightness, and two adjacent sides need to keep higher parallelism. A guide block 12 in sliding fit with the guide groove is arranged on the lower plane of the clamping plate 1, and the guide block and the clamping plate can be connected in a welding mode or a threaded connection mode or a nut connection mode. The arrangement of the guide groove and the guide block can ensure the straightness of the clamping plate when the clamping plate moves along the base, and the deviation is prevented.

When the device is used, a proper clamping groove is selected to place a chip, the screw rod is screwed, the screw rod rotates relative to the nut, the screw rod advances under the action of thread transmission, the first clamping ring pushes the compression spring, the compression spring pushes the second protrusion, and the clamping plate is driven to advance to clamp the chip tightly. After the chip is processed, the screw rod is screwed in the opposite direction, the screw rod retreats under the transmission of the thread, and the second clamping ring pushes the second bulge and the clamping plate to retreat. In this arrangement, the first projection merely serves as a support and does not participate in the transmission of forces.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
