Description

Technical Field

[0001] The utility model relates to the technical field of inspection gauges, in particular to a shift panel inspection gauge. Background Art

[0002] In the production and inspection process of products, the shift panel inspection gauge disclosed in CN208579724U needs to be matched with a go-no go gauge to complete the qualification judgment of the gap between the inner edge of the simulated inspection frame opening and the outer edge of the product. If the GO end of the go-no go gauge passes and the NOGO end does not pass, it is qualified. The go-no go gauge includes a handle, and a go gauge (GO end) and a no-go gauge (NOGO end) respectively installed at both ends of the handle. This kind of go-no go gauge has obvious technical defects: first, the go gauge and the no-go gauge are respectively arranged at both ends of the handle, so the go gauge and the no-go gauge need to be inserted into the gap respectively for inspection, which requires two inspection operations, and the process is relatively cumbersome; second, the specification of the go-no go gauge is fixed, and go-no go gauges of different specifications need to be equipped for gap inspection of different specifications, leading to increased inspection cost and inconvenience in carrying. Contents of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the prior art, and the utility model provides a shift panel inspection gauge, which realizes qualification judgment through a single operation and integrates multi-specification inspection functions.

[0004] The technical solution of the utility model is: a shift panel inspection gauge, comprising a bottom plate, a simulated inspection frame, a clamping device and a go-no go gauge, a product accommodating opening is enclosed inside the simulated inspection frame, the clamping device is used for clamping and positioning the to-be-inspected product in the product accommodating opening, the go-no go gauge is used for inspecting the qualification of the gap between the inner edge of the simulated inspection frame and the outer edge of the to-be-inspected product, the go-no go gauge comprises a handle and a gauge rod set, the gauge rod set is composed of a plurality of coaxially arranged gauge rods, the plurality of gauge rods are coaxially sleeved in sequence from the inside to the outside, and two adjacent gauge rods form an axial sliding fit; a accommodating cavity is arranged inside the handle, an opening is arranged at one end of the handle, the plurality of gauge rods are accommodated in the accommodating cavity and can extend out through the opening, each extended gauge rod is independently locked by a corresponding respective locking assembly, and each retracted gauge rod is independently locked by a corresponding respective magnetic attraction assembly.

[0005] By adopting the above technical solution, through the multi-section coaxially telescopic gauge rods, multiple sections of go gauges / no-go gauges of different specifications can be integrated at the same end of the handle. Hold the handle once, switch between gauge rods of different specifications by telescoping, among the two extended gauge rods, the smaller one serves as the go gauge and the larger one serves as the no-go gauge, so that the inspection can be completed without replacing tools or flipping operations, which solves the problems of cumbersome traditional inspection process and inconvenience in carrying multi-specification tools, and simplifies the operation process of two independent inspections; each gauge rod is independently locked and positioned by magnetic attraction, which ensures that the length is fixed when extending, and the storage is firm when retracting, avoiding accidental telescoping or shifting of the gauge rod during inspection.

[0006] A further feature of this invention is that each locking component includes a locking ball and a locking groove. The locking assembly is provided between any two adjacent gauge rods. The locking groove of the locking assembly is located on the inner wall of the outer gauge rod, and the ball is installed in the ball position hole on the outer wall of the inner gauge rod and is abutted by a spring. The locking assembly is provided between the outermost gauge rod and the handle. The locking groove of the locking assembly is located on the inner wall of the handle receiving cavity, and the ball is installed in the ball position hole on the outermost gauge rod and is abutted by a spring. When the gauge rod extends, the ball of the corresponding locking assembly engages with the locking groove to achieve extension positioning.

[0007] By further configuring the above-mentioned design, a spring-ball-locking groove locking structure is adopted to achieve rapid positioning and unlocking after the gauge rod is extended. The structure is simple, reliable, and easy to operate, solving the problem of unstable positioning in traditional telescopic structures. The spring provides continuous preload, and when the gauge rod extends to the preset position, the ball automatically engages with the locking groove, achieving "positioning upon extension" without the need for additional locking operations. When unlocking, pushing the gauge rod forcefully disengages the ball from the locking groove, ensuring smooth operation.

[0008] A further feature of this invention is that each magnetic component includes a magnetically engaging S pole and a N pole. The magnetic attraction assembly is provided between any two adjacent gauge rod sections, with the S and N poles of the magnetic attraction assembly respectively located in the rear end wall grooves of the two adjacent gauge rod sections; the magnetic attraction assembly is provided between the outermost gauge rod and the handle, with the S and N poles of the magnetic attraction assembly respectively located in the rear end wall grooves of the outermost gauge rod and the handle; when the gauge rod is retracted, the S and N poles of the corresponding locking assembly attract each other to achieve retraction positioning.

[0009] By adopting the above-mentioned further settings, the S and N poles of the magnetic attraction component are precisely attracted to achieve reliable positioning after the gauge rod is retracted. Combined with the locking component, a dual positioning of "extending locking + retracting magnetic attraction" is formed, which further improves the structural stability of the go and no-go gauge.

[0010] A further feature of this invention is that each section of the gauge rod has a specification mark on its surface, which indicates the diameter parameter of the section of the gauge rod.

[0011] By further configuring the above-mentioned settings and adding specification markings to the surface of each gauge rod, the diameter parameters of the currently extended gauge rod can be quickly identified without additional measurement or memorization. This solves the problem of confusion when switching between multiple gauge rod specifications and improves inspection efficiency. The specification markings can be specific numerical values ​​or position markings, etc.

[0012] A further feature of this invention is that each section of the gauge rod has a detection head at its front end, and the end face of the detection head is an arc-shaped guide surface.

[0013] With the above-mentioned further design, the front end of the detection head is provided with an arc-shaped guide surface, which makes the gauge rod easier to insert into the gap, avoids scratching the outer edge of the product or the inner edge of the simulated detection frame, reduces insertion resistance, improves the ease of operation, and protects the detection tool and the product to be tested.

[0014] A further feature of this invention is as follows: the inner wall of the handle receiving cavity is provided with a guide plane I, and the outer wall of the outermost gauge rod is provided with a guide plane II. The guide plane I and the guide plane II slide in axial direction to restrict the rotation of the outermost gauge rod relative to the handle; in two adjacent gauge rod sections, the inner wall of the outer gauge rod is provided with a guide plane A, and the outer wall of the inner gauge rod is provided with a guide plane B6. The guide plane A and the guide plane B slide in axial direction to restrict the relative rotation of the two adjacent gauge rod sections.

[0015] By adopting the above-mentioned further settings, the relative rotation of the gauge rod is restricted by the sliding fit of the guide plane, ensuring that the gauge rod maintains coaxiality when it extends or retracts, avoiding detection offset caused by gauge rod torsion, solving the problem of insufficient detection accuracy of traditional go and no-go gauges, and ensuring the accuracy of gap detection.

[0016] A further feature of this invention is that the handle receiving cavity is provided with two sets of gauge rods of different specifications. The two ends of the handle are respectively provided with openings. The two sets of gauge rods extend out through the openings at the corresponding ends. In each set of gauge rods, the extended gauge rods are independently locked by the corresponding locking components, and the retracted gauge rods are independently locked by the corresponding magnetic components.

[0017] With the above-mentioned further design, two sets of gauge rods of different specifications are set at both ends of the handle, which can integrate more specifications of go / no-go gauges, further expanding the scope of inspection applications, eliminating the need to carry multiple sets of tools, and taking into account both versatility and portability.

[0018] A further feature of this invention is that the base plate is provided with a clamping seat, the clamping seat having a "V"-shaped opening, and the handle of the go / no-go gauge is secured to the clamping seat.

[0019] With the above-mentioned further design, a "V"-shaped clamp is provided on the base plate, which can quickly and securely fasten the go / no-go gauge, avoiding loss or damage caused by careless placement of tools during the inspection process. At the same time, it is easy to access and improves the cleanliness and ease of operation of the inspection process. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-7 As shown, this utility model discloses a shift panel inspection fixture, including a base plate 1, a simulated inspection frame 2, a clamping device 3, and a go / no-go gauge 4. The simulated inspection frame 2 and the clamping device 3 are mounted on the base plate 1. The inner side of the simulated inspection frame 2 encloses a product receiving opening 21. The clamping device 3 is used to clamp and position the product 100 to be inspected within the product receiving opening 21 (the clamping device is a conventional design and will not be described in detail). The go / no-go gauge 4 is used to detect the clearance between the inner edge of the simulated inspection frame 2 and the outer edge of the product to be inspected. The go / no-go gauge 4 includes a handle 4. 1. A guide rod assembly 42, which consists of several coaxially arranged guide rods 421. The guide rods 421 are coaxially sleeved from the inside to the outside, and adjacent guide rods 421 form an axial sliding fit. The handle 41 has a receiving cavity 411 inside, and an opening 412 at one end of the handle 41. The guide rods 421 are received in the receiving cavity 411 and can extend through the opening 412. Each extended guide rod 421 is independently locked by its corresponding locking component 44, and each retracted guide rod 421 is independently locked by its corresponding magnetic attraction component 45.

[0024] Specifically, each locking component 44 includes a ball 441 and a locking groove 442; The locking assembly 44 is provided between any two adjacent gauge rods 421. The locking groove 442 of the locking assembly 44 is located on the inner wall of the outer gauge rod 421. The ball 441 is installed in the ball position hole on the outer wall of the inner gauge rod 421 and is abutted by a spring (the spring is an existing structure and is not shown). The locking assembly 44 is provided between the outermost gauge rod 421 and the handle 41. The locking groove 442 of the locking assembly 44 is located on the inner wall of the handle receiving cavity 411. The ball 441 is installed in the ball position hole on the outer wall of the outermost gauge rod 421 and is abutted by a spring. The part of the ball is located outside the ball position hole. When the gauge rod 421 extends, the ball 441 of the corresponding locking assembly 44 is engaged in the locking groove 442 to achieve extension positioning.

[0025] Specifically, each magnetic component 45 includes a magnetically engaging S pole 451 and an N pole 452. The magnetic attraction component 45 is provided between any two adjacent gauge rods 421. The S pole 451 and N pole 452 of the magnetic attraction component 45 are respectively located in the rear end wall grooves of the two adjacent gauge rods 421. The S pole 451 is located on the inner gauge rod and the N pole 452 is located on the outer gauge rod, or the N pole 451 is located on the inner gauge rod and the S pole 452 is located on the outer gauge rod. The magnetic attraction component 45 is provided between the outermost gauge rod 421 and the handle 41. The S pole 451 and N pole 452 of the magnetic attraction component 45 are respectively located in the rear end wall grooves of the outermost gauge rod 421 and the handle 41. When the gauge rod 421 is retracted, the S pole 451 and N pole 452 of the corresponding locking component 44 are attracted to achieve retraction positioning.

[0026] Specifically, each section of the gauge rod 421 has a specification mark on its surface, which indicates the diameter parameter of this section of the gauge rod.

[0027] Specifically, each gauge rod 421 has a detection head 422 at its front end, and the end face of the detection head 422 is an arc-shaped guide surface 4221.

[0028] Specifically, the inner wall of the handle receiving cavity 411 is provided with a guide plane I 414, and the outer wall of the outermost gauge rod 421 is provided with a guide plane II 424. Guide plane I 414 and guide plane II 424 slide in axial direction to restrict the rotation of the outermost gauge rod 421 relative to the handle 41. Among two adjacent gauge rod sections 421, the inner wall of the outer gauge rod 421 is provided with a guide plane A 425, and the outer wall of the inner gauge rod 421 is provided with a guide plane B 426. Guide plane A 425 and guide plane B 426 slide in axial direction to restrict the relative rotation of the two adjacent gauge rod sections 421. Several gauge rod sections have a polygonal prism structure, such as a hexagonal prism.

[0029] Specifically, the handle receiving cavity 411 is provided with two sets of gauge rod groups 42 of different specifications. The handle 41 has openings 412 at both ends. The two sets of gauge rod groups 42 extend out through the openings 412 at the corresponding ends. The extended gauge rods 421 in each set of gauge rod groups 42 are independently locked by the corresponding locking components 44, and the retracted gauge rods 421 are independently locked by the corresponding magnetic components 45.

[0030] Specifically, the base plate 1 is provided with a clamping seat 5, which is mounted on the base plate by screws. The clamping seat 5 is a "V" shaped open clamp, and the handle 41 of the go / no-go gauge 4 is clamped on the clamping seat 5.

[0031] The specific working process of this shift panel inspection tool is as follows: (1) Product clamping and positioning: Place the shift panel to be tested into the product receiving port of the simulated test frame 2, and clamp and fix the product by the clamping device 3 to ensure that the product does not shift during the test and to ensure the stability of the test reference.

[0032] (2) Use of go / no-go gauge and gauge rod switching: Take out the go / no-go gauge 4 from the "V" shaped clamp 5 of the base plate 1, and select the corresponding gauge rod group 42 according to the preset specification of the gap to be tested: If the gauge rod assembly 42 at one end of the handle 41 is used, the inner gauge rod 421 is pulled forward towards the opening 412, and the adjacent gauge rods 421 slide and extend along the axial direction; when the gauge rod 421 extends to the preset stroke, the spring-push ball 441 in the locking assembly 44 automatically engages with the locking groove 442 on the inner wall of the outer gauge rod 421 or the handle receiving cavity 411 to achieve extension positioning. At this time, one section of the gauge rod can be selected as the go gauge (GO end) and the other section of the gauge rod with a slightly larger diameter can be selected as the no-go gauge (NOGO end). When retracting the gauge rod, press the extended gauge rod 421 into the receiving cavity 411. The locking ball 441 is compressed by the inner wall of the locking groove 442, and can be unlocked by disengaging from the locking groove 442. Under the attraction of the S pole 451 and N pole 452 of the magnetic attraction component 45, the gauge rod 421 automatically retracts and is firmly stored in the receiving cavity 411 to prevent movement. During testing, only two required gauge rods can be extended, while the rest are retracted. Any two extended gauge rods can form a go gauge and a no-go gauge, allowing for a wide range of testing options. During testing, the specifications of the go and no-go gauges are confirmed by the markings on the surface of the gauge rod 421. The arc-shaped guide surface 4221 of the go gauge testing head 422 is aligned with the gap between the inner edge of the simulated testing frame 2 and the outer edge of the product, and then inserted smoothly. If the go gauge passes through the gap smoothly and the no-go gauge cannot be inserted into the gap, the product gap is considered acceptable. If other clearance specifications need to be checked, another set of gauge rods 42 can be switched at the other end of handle 41. The operation logic is the same as above. The two sets of gauge rods work independently and do not interfere with each other.

[0033] (3) After the test is completed, press all the extended gauge rods 421 to retract them into the receiving cavity 411. The S pole 451 and N pole 452 of the magnetic suction assembly 45 are attracted to achieve retraction and positioning. Then, reinstall the go / no-go gauge 44 back into the "V" shaped clamp 5 to complete the tool storage.

[0034] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0035] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
