In order to ensure that the steel sleeves meet the relevant standards and requirements, they need to be accurately inspected. However, the shapes and sizes of steel sleeves are diverse, and they need to be inspected in specific positions and postures, which puts high demands on the fixture.

[0003] In the past, the traditional method of positioning and fixing the steel sleeve was mainly to clamp and fix it with flat-nose pliers, which was cumbersome to operate, the force was uncontrollable, and the product was easily deformed. Therefore, there is an urgent need for a steel sleeve detection and positioning fixture that can quickly and accurately fix the position of the steel sleeve to ensure its stability and repeatability during the detection process. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a detection and positioning fixture for a steel sleeve, which is simple to operate and can quickly and accurately locate and fix the position of the steel sleeve.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a detection and positioning fixture for steel sleeves, comprising a group of relatively arranged side plates, a plurality of top columns arranged on the side plates, and a base sandwiched between two of the side plates;

[0006] Among them, a plurality of V-shaped sinking grooves are arranged on the base, and each of the top columns is floated on the side plate toward the V-shaped sinking groove through an elastic member, and is surrounded by the side wall of the V-shaped sinking groove to form a station for placing the steel sleeve.

[0007] Optionally, the side plate is provided with a plurality of countersunk holes, the top column is movably inserted into the countersunk holes, and one end of the top column can pass through an opening at one end of the countersunk holes;

[0008] The elastic member comprises a spring and a top cover screw threadedly connected to one end of the countersunk hole, and two ends of the spring elastically abut against the top cover screw and the top column respectively.

[0009] Optionally, the side plate is threadedly connected with a limit screw capable of abutting against the outer periphery of the top cover screw.

[0010] Optionally, the side panels and the base are both arranged on a support plate, and a flippable handle is provided on the support plate.

[0011] Optionally, a plurality of workstations formed by the top columns and the V-shaped sinking grooves are symmetrically distributed on the base along the symmetry axis of the base.

[0012] Optionally, the base includes a bottom plate and a positioning plate detachably connected to the middle of the bottom plate, the positioning plate is provided with a plurality of V-shaped notches, and the V-shaped notches and the bottom plate are arranged to form a V-shaped sinking groove.

[0013] Optionally, a plurality of groups of right-angle notches are symmetrically arranged on the side walls of the V-shaped notch.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) When the steel sleeve is placed in the work station, the top column can be pressed against one side to compress the elastic member and accumulate energy. When the steel sleeve is completely placed in the work station, the elastic member can drive one end of the top column to press against the outer periphery of the steel sleeve, so that the outer periphery of the steel sleeve can press against the two side walls of the V-shaped sinking groove. The operation is simple and quick, and the positioning fixture can meet the positioning requirements of steel sleeves of various sizes by positioning the steel sleeve at three points.

[0016] (2) By adjusting the depth of the top cover screw embedded in the countersunk hole, the force of the spring acting on the outer periphery of the steel sleeve through the top column and the reaction force of the side wall of the V-shaped sinking groove acting on the outer periphery of the steel sleeve can be limited within a certain range, which can effectively avoid the extrusion deformation of the steel sleeve.

[0026] like Figure 1-Figure 5 As shown, a steel sleeve detection and positioning fixture comprises a set of side plates 1 arranged opposite to each other, a plurality of top columns 2 arranged on the side plates 1, and a base 3 clamped between the two side plates 1;

[0027] Among them, a plurality of V-shaped sinking grooves 301 are arranged on the base 3, and each top column 2 is floated on the side plate 1 toward the V-shaped sinking groove 301 through an elastic member, and is surrounded by the side wall of the V-shaped sinking groove 301 to form a station 4 for placing the steel sleeve.

[0028] Specifically, the top column 2 and the V-shaped sinking groove 301 act on the outer periphery of the steel sleeve in the same position range to prevent the steel sleeve from tipping over due to uneven force. At the same time, when the steel sleeve is placed in the work station 4, the top column 2 can be pressed against one side to compress the elastic member and accumulate energy. When the steel sleeve is completely placed in the work station 4, the elastic member can drive one end of the top column 2 to press against the outer periphery of the steel sleeve, so that the outer periphery of the steel sleeve can press against the side wall of the V-shaped sinking groove 301, and the three-point positioning of the steel sleeve is realized. The operation is simple and the operation requirements are low. In addition, the technical solution adopts the V-shaped sinking groove 301 to cooperate with the top column 2 to act on the outer periphery of the steel sleeve, which can meet the positioning of steel sleeves of various sizes, and can limit the force of the top column 2 acting on the outer periphery of the steel sleeve and the reaction force of the side wall of the V-shaped sinking groove 301 acting on the outer periphery of the steel sleeve to a certain range through the elastic member, which can effectively avoid product extrusion and deformation.

[0029] The above, such as Figure 1-Figure 3 As shown, a plurality of countersunk holes 101 are provided on the side plate 1, and the top column 2 is movably arranged in the countersunk hole 101, and one end of the top column 2 can pass through the opening of one end of the countersunk hole 101; the elastic member includes a spring 5 and a top cover screw 6 screwed on one end of the countersunk hole 101, and the two ends of the spring 5 elastically abut against the top cover screw 6 and the top column 2 respectively. In this technical solution, the cross section of the top column 2 is in a "convex" shape, and the top column 2 can only extend from one end of the countersunk hole 101 that can be threaded with the top cover screw 6, and one end can only be partially penetrated from the other end, so under the action of the spring 5, the end of the top column 2 that passes through the countersunk hole 101 can stably abut against the outer periphery of the steel sleeve. The force of the top column 2 acting on the steel sleeve can be achieved by replacing springs 5 ​​of different models, or by adjusting the depth of the top cover screw 6 screwed in the countersunk hole 101 to increase or decrease the elastic force accumulated by the spring 5. In order to ensure that the outer periphery of the steel sleeve is not damaged, the steel sleeve can be stably positioned and fixed on the base 3.

[0030] The above, such as Figure 3 As shown, a limit screw 7 is threadedly connected to the side plate 1 and can abut against the outer periphery of the top cover screw 6 to prevent the top cover screw 6 from rotating and loosening.

[0031] As mentioned above, the side plate 1 and the base 3 are both arranged on the support plate 8, and the support plate 8 is provided with a flippable handle 9, which is symmetrically arranged on the support plate 8 along the axis of symmetry of the base 3, and the operator can carry and move the positioning fixture through the handle 9. At the same time, the workstations 4 formed by a plurality of top columns 2 and V-shaped sinking grooves 301 are symmetrically distributed on the base 3 along the axis of symmetry of the base 3, so as to ensure the balance of the center of gravity of the positioning fixture when multiple steel sleeves are carried on the positioning fixture, so as to facilitate the subsequent operators to carry the positioning fixture and the steel sleeve thereon. Embodiment 2

[0032] like Figure 4As shown, on the basis of the first embodiment, different from directly opening a V-shaped sinking groove 301 on the base 3, the base 3 includes a bottom plate 31 and a positioning plate 32 detachably connected to the middle of the bottom plate 31, and a plurality of V-shaped notches 321 are opened on the positioning plate 32, and the V-shaped notches 321 and the bottom plate 31 are surrounded to form a V-shaped sinking groove 301. The base 3 adopts a split structural design, and the positioning plate 32 and the bottom plate 31 can be disassembled and connected by fasteners such as bolts, so as to replace the positioning plate 32 with V-shaped notches 321 of different specifications and sizes, increase the diversity of the positioning fixture, and meet different positioning requirements.

[0033] Further, such as Figure 5 As shown, a plurality of groups of right-angle notches 3211 are symmetrically arranged on the side wall of the V-shaped notch 321, so that the positioning fixture in the technical solution can be applicable not only to the positioning of the circular steel sleeve, but also to the positioning of some square steel sleeves.

[0034] Working principle: When the steel sleeve is placed in the work station 4, the push column 2 can be pressed against one side to compress the spring 5 and accumulate energy. When the steel sleeve is completely placed in the work station 4, the spring 5 can drive one end of the push column 2 to press against the outer periphery of the steel sleeve, so that the outer periphery of the steel sleeve can press against the side wall of the V-shaped sinking groove 301, thereby realizing three-point positioning of the steel sleeve. The operation is simple, convenient and fast, and can meet the positioning needs of steel sleeves of various sizes. The spring 5 can limit the force of the push column 2 on the outer periphery of the steel sleeve and the reaction force of the side wall of the V-shaped sinking groove 301 on the outer periphery of the steel sleeve to a certain range, thereby effectively avoiding extrusion and deformation of the product.

[0035] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
