Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle inspection tools, and in particular to a general-purpose platform inspection tool. Background Technology

[0002] Traditional inspection tools for electric two-wheeled vehicles are generally designed for single-vehicle use, resulting in poor versatility. Furthermore, the installation of inspection pins requires the use of die-cast gaskets for limiting and fixing, necessitating high precision in bolt holes, leading to high costs and poor interchangeability.

[0003] Traditional gauges often use slopes for positioning the steel cup at the fixed position, which requires high precision in height and angle, is troublesome to adjust, and has low material utilization of the inspection point support.

[0004] Traditional inspection pin assemblies consist of inspection pins, motion shafts, fixed pads, and grips. They are costly, have few suppliers, poor market penetration, low usage frequency, cumbersome maintenance, and frequent disassembly and assembly can damage the screw threads, affecting the accuracy of the inspection tool.

[0005] For large-scale car manufacturers, the aforementioned defects mean that, given the large number of vehicle models they produce, the inspection tools used for each new model need to undergo wire cutting and machining, resulting in a large workload and high costs. Utility Model Content

[0006] To address the shortcomings of existing production technologies, the applicant provides a universal platform inspection tool with a modular assembly structure, suitable for inspecting more vehicle specifications. It also employs standardized inspection pins and forward tilt angle inspection columns with inspection holes, reducing costs and simplifying the inspection process.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A general-purpose platform inspection tool includes a base, on which a front detection component, a rear detection component, and a body limiting component are mounted;

[0009] The front inspection component includes a front inspection base and a slide rail assembly located on the front inspection base. A front mounting point inspection fixture is mounted on the top surface of the slide rail assembly. The slide rail assembly drives the front mounting point inspection fixture to slide back and forth along the line connecting the front and rear of the vehicle.

[0010] The rear-end inspection component includes a rear-end inspection base, on which a fixture base plate is provided, and a rear-end mounting point fixture is pre-installed on the fixture base plate.

[0011] The vehicle body limiting assembly includes a detection pin for inserting into the frame through-hole and a cylinder for pushing the detection pin; all detection pins are of uniform specifications.

[0012] As a further improvement to the above technical solution:

[0013] The slide rail assembly includes a base plate located on the front inspection seat, a slide plate located above the base plate, and a self-locking slide rail located between the base plate and the slide plate.

[0014] The skateboard is equipped with a forward tilt angle measuring post, which is located on the side of the front mounting point gauge facing the vehicle frame.

[0015] The tilt angle measuring column is made of CNC machined parts, and the top center of the tilt angle measuring column has a hole for accommodating the head tube of the vehicle frame to be tested.

[0016] The tilt angle of the forward tilt angle measuring column on the slide plate is the same as the theoretical tilt angle of the head tube of the frame under test.

[0017] The front detection component, rear detection component, and base are detachably connected.

[0018] The rear-end inspection component includes a rear-end mounting point fixture and a calibration frame set on both sides of the rear-end mounting point fixture.

[0019] The test pins include:

[0020] The handle is pushed by the cylinder.

[0021] The bushing is located at the end of the handle opposite to the cylinder.

[0022] The movable column extends towards the bushing at the end away from the handle.

[0023] The rubber ring is located at the end of the movable column away from the bushing.

[0024] The test pin has a stepped shaft structure, and the outer diameter of the stepped shaft gradually decreases from the end near the cylinder to the end of the vehicle frame to be tested.

[0025] The mounting surfaces of the front detection component, rear detection component, and body limiting component are all horizontal.

[0026] The beneficial effects of this utility model are as follows:

[0027] By building an inspection platform, the cost of inspection tools is reduced and efficiency is improved. This application constructs a platform inspection tool combination based on the selected vehicle platform. The bracket adopts horizontal and vertical tilting to increase the vehicle frame assembly space, so as to accommodate the inspection of more vehicle models. In addition, in the horizontal and vertical tilting structure, the uprights, reinforcing pillars and tilting plates can be made into components that can be separated by wire cutting to reduce costs.

[0028] Standardizing the size of the inspection pins reduces unit costs, extends lifespan, and simplifies maintenance. This application selects four commonly used inspection pin sizes in conjunction with a flip-plate mechanism for point inspection. The inspection pins can be mass-produced and integrally formed on a lathe. The cost of a single inspection pin assembly is around 65 yuan, compared to around 150 yuan for the old version, representing a cost reduction of more than half.

[0029] The tilt angle detection column uses a CNC-machined fixed angle boss, which is easy to adjust and has high precision. The old-style inspection tool requires the steel cup under the front of the car to be fixed to the front inspection plate, and the angle of the front inspection plate is adjusted to adjust the angle of the front tube. Using a CNC-machined inclined boss, it is only necessary to ensure the parallelism between the slide rail mechanism and the inspection tool base. The tilt angle of the frame is guaranteed by the tilt angle detection column process (CNC machining), and it is screwed to the slide rail assembly, which has high precision and high interchangeability.

[0042] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0043] like Figures 1-6 As shown, the general platform inspection tool of this embodiment includes a base 4, on which a front detection component 1, a rear detection component 2 and a body limiting component 3 are provided;

[0044] The front inspection component 1 includes a front inspection seat 101 and a slide rail assembly located on the front inspection seat 101. A front mounting point gauge 102 is installed on the top surface of the slide rail assembly. The slide rail assembly drives the front mounting point gauge 102 to slide back and forth along the line connecting the front and rear of the vehicle.

[0045] The rear-end inspection component 2 includes a rear-end inspection seat 201, on which a fixture base plate 202 is provided, and a rear-end mounting point fixture 204 is pre-installed on the fixture base plate 202.

[0046] The vehicle body limiting assembly 3 includes a detection pin 303 for extending into the frame through hole and a cylinder 302 for pushing the detection pin 303; all detection pins 303 are of uniform specifications.

[0047] The slide rail assembly includes a base plate 103 located on the front detection seat 101, a slide plate 104 located above the base plate 103, and a self-locking slide rail 105 located between the base plate 103 and the slide plate 104.

[0048] The skateboard 104 is equipped with a forward tilt angle measuring post 106, which is located on the side of the front mounting point gauge 102 facing the frame.

[0049] The tilt angle measuring column 106 is a CNC machined part, and the top center of the tilt angle measuring column 106 has a hole for accommodating the head tube of the vehicle frame to be tested.

[0050] The tilt angle of the forward tilt angle measuring column 106 on the slide plate 104 is the same as the theoretical tilt angle of the head tube of the frame under test.

[0051] The front detection component 1, the rear detection component 2, and the base 4 are detachably connected.

[0052] The rear inspection component 2 includes a rear mounting point gauge 204 and a correction frame 203 set on both sides of the rear mounting point gauge 204.

[0053] Test pin 303 includes:

[0054] Handle 304 is pushed by cylinder 302.

[0055] Bushing 305 is located at the end of handle 304 opposite to cylinder 302.

[0056] The movable column 306 extends toward the bushing 305 at the end opposite to the handle 304.

[0057] Rubber ring 307 is located at the end of movable column 306 opposite to bushing 305.

[0058] The detection pin 303 has a stepped shaft structure, and the outer diameter of the stepped shaft gradually decreases from the end near the cylinder 302 to the end of the vehicle frame to be tested.

[0059] The mounting surfaces of the front detection component 1, the rear detection component 2, and the body limiting component 3 are all horizontal.

[0060] The specific structure and working process of this application are as follows:

[0061] like Figure 1 The diagram shows the platform fixture of this application in use. A vehicle frame to be inspected is placed on the platform fixture, in the inspection state.

[0062] The chassis platform inspection fixture includes a base 4, on which the front inspection component 1, the rear inspection component 2, and the body limiting component 3 are assembled and placed.

[0063] The base 4 is a base plate 103 with brakeable rollers. Its size is larger than the sum of the sizes of the vehicle to be tested and all testing components and limiting components, so that the testing components can be adjusted on the base 4 and adapted to various types of vehicles.

[0064] The specific structure of the front detection component 1 is shown in the reference. Figure 2-1 , Figure 2-2 , Figure 2-3 It includes a front inspection seat 101 mounted on the base 4 and a slide rail assembly mounted on the front inspection seat 101; a front mounting point inspection fixture 102 is mounted on the slide rail assembly.

[0065] The front inspection seat 101 has a cubic structure and its main function is to support the front mounting point inspection fixture 102 so that the front mounting point inspection fixture 102 can be adapted to the height of the front of the vehicle.

[0066] The slide rail assembly includes a base plate 103 and a slide plate 104. A slide rail 105 is provided between the base plate 103 and the slide plate 104, allowing the slide plate 104 to slide relative to the base plate 103. A front mounting point gauge 102 and a forward tilt angle measuring column 106 screwed onto the slide plate 104 are mounted on the slide plate 104. The forward tilt angle measuring column 106 is a CNC-cut column with a countersunk hole. Unlike conventional measuring column detection methods, in this embodiment, the forward tilt angle measuring column 106 only needs to be tested by determining whether the front lower tube can be smoothly inserted into the forward tilt angle measuring column.

[0067] The purpose of the slide rail assembly is to facilitate the movement of the inspection fixture 102 from the front of the vehicle to be inspected. Although the relative position of the front inspection seat 101 to the vehicle can be adjusted by disassembly and reassembly, the addition of the slide rail assembly further simplifies the displacement action. The typical usage is to fix the front inspection seat 101 according to the dimensions of a specific vehicle frame, and then, during the inspection process, use the reciprocating sliding of the slide rail assembly to achieve limiting and releasing.

[0068] The slide rail 105 used above can be a commercially available slide rail with a braking function to provide reliable braking when moving to a designated position. Self-locking slide rails, such as TT-1545TOP(IT) slide rails and FX3076 slide rails, can be used.

[0069] like Figure 3 As shown, the rear-end inspection component 2 includes a rear-end inspection base 201, on which a fixture base plate 202 is mounted. A calibration frame 203 and a rear-end mounting point fixture 204 are mounted on the fixture base plate 202. The rear-end mounting point fixture 204 can be an existing fixture. To adapt to vehicles of different specifications, the fixture base plate 202, the calibration frame 203 on the fixture base plate 202, and the rear-end mounting point fixture 204 are pre-installed modules. By adjusting the installation position between the rear-end inspection base 201 and the base 4, or by adjusting the installation position between the fixture base plate 202 and the rear-end inspection base 201, different vehicle frames can be adapted.

[0070] Vehicle body limiting components 3 are also provided on both sides of the base 4. The vehicle body limiting components 3 are as follows: Figure 4 and Figure 5 As shown, it is mainly used to check whether the holes on the vehicle body are accurate. The vehicle body limiting component 3 comes in two specifications, one of which is as follows: Figure 4 The detection structure shown includes a single-piece gauge 301 and a single cylinder 302. One type is as follows: Figure 5 The diagram shows the detection structure of the single-piece gauge 301 and the dual cylinders 302 on both sides. During testing, the gauge 301 is placed on the base 4 inside the frame, and the cylinders 302 point from the outside to the inside, pushing the detection pin 303 through the through hole on the frame to match the gauge 301 inside, thus completing the positional accuracy test.

[0071] like Figure 6As shown, the detection pin 303 used in this application is a detection pin 303 with a unified specification. The detection pin 303 includes a handle 304, a bushing 305, a movable column 306, and a rubber ring 307. The handle 304 is clamped by a cylinder 302. The movable column 306 is the detection main body and is used to extend into the through hole to be detected. The rubber ring 307 is arranged between the top end of the movable column 306, the handle 304, and the bushing 305 to reduce the damage caused by rigid impact. In the detection pin 303 of this embodiment, the stepped plate structure in the middle section and the stepped structure at the end of the conventional detection pin 303 are cancelled, and a structure with a gradually decreasing size from the handle 304 is adopted. Universal detection is achieved through multiple coaxial stepped shafts.

[0072] During use, insert the air pump. First, place the vehicle frame on the base for inspection preparation. Align the vehicle frame with the main positioning surface of the vehicle frame, that is, the flat fork inspection surface. Turn on the air pump switch. If the cylinder 302 can smoothly push the main reference pin 4 into it, it is qualified. Secondly, it is required that the auxiliary reference pin 1 of the vehicle frame can smoothly enter, that is, the front head tube can smoothly insert into the forward tilt angle detection column. Use a feeler gauge to measure within the range of ±0.2 mm of the lower end face of the head tube and the slide rail scale is within + / -2, which is qualified. Then, flip the inspection block 3 on the upper part of the head tube to the product position. The inspection pin can enter the hole, and it is qualified within the range of -0.5 to +1.5 mm between the inspection block surface and the product surface. Finally, insert other detection pins 303. Insert other detection pins 303 in sequence according to the operation specification process table of the vehicle frame. Each point needs to meet the error range requirements of the operation specification.

[0073] Compared with the conventional technology, the advantages of this application are as follows:

[0074] Only the parallelism between the slide rail assembly and the base 4 needs to be ensured. The forward tilt angle of the vehicle frame is ensured by the forward tilt angle detection column process (CNC), and it is in a screwed connection state with the slide rail assembly, with strong precision and interchangeability. For the old-fashioned inspection tool, the parallelism between the forward tilt angle detection column of the vehicle frame and the inclined plate and the included angle between the inclined plate and the bottom plate 103 need to be ensured at the head position of the vehicle frame. The inclined plate and the vertical plate are in a welded state, with poor precision and interchangeability.

[0075] In the new version of the platform inspection tool, the platform parts are the head tube, main beam tube, upper and lower side tubes, side tube reinforcement plates, front and rear footrest brackets, seat bucket mounting brackets, flat fork plates, shock absorber hangers, and rear cross tubes. The rest of the brackets and installation points are special parts for the vehicle frame. If other vehicle frame inspections are required, only the mounting plate equipped with the detection pin 303 needs to be replaced.

[0076] The old version of the detection pin consists of a handle, a limit block, a movable column, and a detection head. The movable column and the detection head need to be processed separately, and the cost is about 150 yuan. The new version of the detection pin 303 consists of a handle 304, a bushing 305, a movable column 306, and a rubber ring 307. The movable column 306 is processed once by a CNC lathe, and the bushing 305 is widely used and easy to source. The cost is about 65 yuan. The cost is significantly reduced.

[0077] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
