Description

Technical Field

[0001] The invention relates to the field of product positioning, in particular to an automatic clamping tool for an aluminum shaft sleeve. Background Art

[0002] In the early stage of the aluminum sleeve product, the surface of the tooling plate is used as the reference. The end face of the aluminum sleeve is pressed by a pressure plate, and then the inner hole of the aluminum sleeve is tightened by an expansion sleeve. After the aluminum sleeve is tightened by the expansion sleeve, the pressure plate is removed, and then the surface and structural groove of the aluminum sleeve are milled. However, when there is more than one inner hole in the aluminum sleeve, this press-fitting and clamping method requires the expansion sleeve to tighten and press each inner hole of the aluminum sleeve separately, which has the problem of over-positioning, often resulting in insufficient consistency in product thickness. Unqualified product thickness will also lead to unqualified structural grooves. In addition, there is the problem of cumbersome clamping, which has a certain impact on the production of aluminum sleeves. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic clamping tool for an aluminum sleeve to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1, see Figure 1-2, an automatic clamping tool for an aluminum sleeve, comprising a cylinder body 9 with a wedge-shaped slot 18 inside, a positioning plate 3 relatively fixed above the cylinder body 9, a movable positioning plate 5 provided between the positioning plate 3 and the cylinder body 9, and a convex body 17 extending from the upper surface of the movable positioning plate 5 and penetrating the positioning plate 3; a telescopic device 15 relatively fixed at the bottom of the cylinder body 9, a pull rod 10 extending into the wedge-shaped slot 18 is fixedly connected to the telescopic end of the telescopic device 15, an oblique block 19 is fixed on the outer side wall of the pull rod 10, an oblique lever 6 is also slidably connected in the wedge-shaped slot 18, the oblique lever 6 is fixedly connected to the movable positioning plate 5, an oblique limit groove 20 is provided on the outer side wall of the oblique lever 6 relative to the pull rod 10, and the oblique block 19 and the oblique limit groove 20 are correspondingly slidably matched.

[0018] like Figure 4 FIG. 1 is a structural diagram of a product applicable to this embodiment. Figure 4 The aluminum sleeve of the product has two inner holes, and the movable positioning plate 5 is correspondingly provided with two. Initially, the bottom surface of the product 2 is used as the reference surface, and the protrusion 17 penetrates the positioning plate 3 and extends into the inner hole of the product 2. The side wall of the inner hole of the product 2 and the outer wall of the protrusion 17 are separated by a pin 1. The pin 1 is used to initially position the position of the product 2 to ensure the consistency of the product position.

[0019] In this embodiment, the movable positioning plate 5 and the inclined lever 6 are connected and fixed by a first screw 4. The outer wall of the inclined lever 6 is an inclined surface adapted to the wedge-shaped slot 18. In this embodiment, a group of inclined levers 6 is provided, and the two inclined levers 6 in a group are symmetrically distributed about the cylinder body 9.

[0020] In this embodiment, the pull rod 10 is coaxial with the cylinder body 9, and the inclined block 19 fixed on the outer wall of the pull rod 10 slides with the inclined limit groove 20. At the same time, the pull rod 10 and the telescopic end of the telescopic device 15 are fixedly connected by the third screw 13 and the locking nut 12.

[0021] In this embodiment, Figure 3 As shown, a positioning groove 23 is provided on the surface where the end of the inclined block 19 cooperates with the inner wall of the inclined limiting groove 20 , and a positioning protrusion 24 extends from the inner wall of the inclined limiting groove 20 corresponding to the positioning groove 23 .

[0022] In this embodiment, in order to better fix the telescopic device 15 and ensure the consistency of product positioning, the bottom of the cylinder body 9 is fixed with a support plate 14 and a tooling bottom plate 16 in sequence, the telescopic device 15 is fixed on the upper surface of the tooling bottom plate 16, the bottom surface of the support plate 14 is provided with a first notch 21 to avoid the telescopic device 15, and the inner bottom surface of the first notch 21 is provided with a second notch 22 for the telescopic end of the telescopic device 15 to pass through. In this embodiment, the telescopic device 15 is preferably a hydraulic cylinder or a pneumatic cylinder, which is low in cost and has stable contraction.

[0023] When implementing this embodiment, first use the bottom surface of the product 2 as the reference surface, then move the protrusion 17 of the positioning plate 5 through the positioning plate 3 and extend into the inner hole of the product, initially position the product 2 through the pin 1, and then retract the telescopic end of the telescopic device 15 to drive the pull rod 10 to descend, and the inclined block 19 fixed on the pull rod 10 is slidably connected with the oblique limit groove 20 in the oblique lever 6, and the positioning groove 23 is obliquely matched with the positioning protrusion 24, thereby driving the oblique lever 6 to move downward.

[0024] Since the outer wall of the inclined lever 6 and the wedge-shaped slot 18 are matched to form an inclined surface, when the inclined lever 6 is pulled down, the movable positioning plate 5 fixed to the upper surface of the inclined lever 6 applies force outward, and the protrusion 17 abuts against the side wall of the inner hole of the product 2 and the pin 1, thereby realizing the position positioning of the product 2.

[0025] In this embodiment, the upper and lower surfaces of the cylinder body 9 are respectively detachably fixed with an upper cover plate 7 and a lower cover plate 11. The upper cover plate 7 and the lower cover plate 11 are connected and fixed to the cylinder body 9 by a second screw 8, which can prevent the processed chips from falling into the cylinder body 9 when the product is processed by a milling cutter.

[0026] When the product has more than two inner holes, the number of movable positioning plates 5 and inclined levers 6 corresponds to the number of inner holes of the product, and is evenly distributed around the cylinder body 9. The inclined blocks 19 on the pull rod 10 also cooperate with the oblique limit grooves 20 in each inclined lever 6. After the protrusion 17 extends into the inner hole of the product 2, the telescopic end of the telescopic device 15 drives the pull rod 10 to descend. Since the movable positioning plates 5 and the inclined levers 6 are evenly distributed, the position of the product 2 can be kept consistent during positioning, thereby improving the position accuracy during product processing.

[0027] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0028] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
