Description

Technical Field

[0001] This utility model is applicable to the field of testing equipment, and in particular relates to a vehicle body testing posture adjustment device. Background Technology

[0002] The static stiffness of the body-in-white is an important performance indicator of passenger car body structure. The quality of the static stiffness of the body-in-white affects the safety, handling, comfort and NVH performance indicators of the car. Therefore, the design, simulation and testing of the static stiffness of the body-in-white is of great significance.

[0003] During the body-in-white rigidity test, see Figure 1 Generally, multiple jacks are used to adjust the vehicle's height and horizontal position. This method of adjustment cannot make fine adjustments to the vehicle's lateral and longitudinal displacement. When fine adjustments to lateral and longitudinal displacement are required, the vehicle must be repeatedly hoisted and aligned, which is cumbersome and time-consuming.

[0004] In summary, the problems existing in the relevant technologies urgently need to be solved. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art and to provide a vehicle body test posture adjustment device.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A vehicle body test attitude adjustment device, comprising:

[0008] A vehicle assembly includes a limiting vehicle, a top block, and a limiting cover. The limiting vehicle has a recessed cavity at its top, and a limiting baffle is formed around the cavity. The top block includes a base and a top post extending upward from the base. The base is disposed in the cavity, and a first adjustment interval is provided between the base and the limiting baffle. The base is supported on the limiting vehicle by a plurality of lower ball bearings disposed at the bottom of the cavity. The limiting cover is installed on the top of the limiting vehicle and has a clearance hole. The top post passes through the clearance hole, and a second adjustment interval is provided between the top post and the clearance hole.

[0009] The jack is connected at the top to the limiting carrier.

[0010] In some implementations, the limiting carrier includes a disc body with a circular limiting wall and a circular cavity inside the limiting wall. The base is circular and its outer diameter is smaller than the inner diameter of the cavity.

[0011] In some implementations, the top post extends upward along the centerline of the base, and the outer diameter of the top post is smaller than the inner diameter of the clearance hole.

[0012] In some implementations, the bottom of the disc body is provided with a connecting seat extending downward along the center line, and the top of the jack is connected to the connecting seat.

[0013] In some implementations, the bottom of the connecting seat is provided with a connecting hole extending along the center line, the connecting hole is provided with an internal thread, and the top of the jack is threadedly connected to the connecting hole.

[0014] In some implementations, the limiting carrier is provided with a guide groove that penetrates the limiting wall and extends circumferentially, the base is provided with a positioning arm that extends outward through the guide groove, the limiting carrier is provided with a positioning seat on the outside of the guide groove, and the positioning arm and the positioning seat are provided with pin holes for inserting positioning pins.

[0015] In some implementations, in conjunction with the above implementations, the guide groove includes a first guide groove and a second guide groove symmetrically disposed on the limiting carrier, the positioning arm includes a first positioning arm and a second positioning arm symmetrically disposed on both sides of the base, and the positioning seat is a first positioning seat and a second positioning seat symmetrically disposed on both sides of the limiting carrier.

[0016] In some implementations, the limiting carrier is provided with a plurality of lower ball bearing mounting grooves at the bottom of the cavity, the lower ball bearings are mounted in the lower ball bearing mounting grooves, and the top of the lower ball bearings protrudes from the lower ball bearing mounting grooves to support the bottom end face of the base.

[0019] One of the above technical solutions has at least one of the following advantages or beneficial effects: In the technical solution of this utility model, the top block of the vehicle assembly is installed in the cavity of the limiting vehicle and supported by multiple lower ball bearings. Since there is a certain gap between the base of the top block and the limiting wall, the top block can have a certain multi-directional translational adjustment capability in the cavity of the limiting vehicle. In specific use, the vehicle assembly is combined with the jack, that is, the top of the jack is connected to the limiting vehicle to form a set of support units. Thus, the vehicle body can be supported at a certain height by pushing the vehicle assembly with the jack.

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0030] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0031] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0032] See Figures 2-4This utility model provides a vehicle body test posture adjustment device, including a carrier assembly 100 and a jack 200. The carrier assembly 100 includes a limiting carrier 101, a top block 102, and a limiting cover 103. The top of the limiting carrier 101 has a recessed cavity 104, and a limiting baffle 105 is formed around the cavity 104. The top block 102 includes a base 106 and a top post 107 extending upward from the base 106. The top post 107 is used to adapt to the vehicle body's raised position. The base 106 is disposed in the cavity 104, and a first adjustment interval is left between the base 106 and the limiting baffle 105. The limiting baffle 105 limits the maximum translation range of the top block 102 in the cavity 104. The base 106 is supported on the limiting carrier 101 by a plurality of lower ball bearings 108 disposed at the bottom of the cavity 104. The lower ball bearings 108 provide omnidirectional movement and bear load force. The limiting cover 103 is installed on the top of the limiting carrier 101. The limiting cover 103 is provided with a clearance hole 109. The top post 107 passes through the clearance hole 109, and a second adjustment interval is left between the top post 107 and the clearance hole 109. The top of the jack 200 is connected to the limiting carrier 101.

[0033] See Figures 2-6 In the technical solution of this utility model, the top block 102 of the carrier assembly 100 is installed in the cavity 104 of the limiting carrier 101 and supported by multiple lower ball bearings 108. Since there is a certain gap between the base 106 of the top block 102 and the limiting baffle 105, the top block 102 can have a certain multi-directional translational adjustment capability in the cavity 104 of the limiting carrier 101. In specific use, the carrier assembly 100 is combined with the jack 200, that is, the top of the jack 200 is connected to the limiting carrier. The 101 connection forms a set of support units, which can support the vehicle body 300 at a certain height by pushing the carrier assembly 100 with the jack 200. Furthermore, the top block 102 has a certain multi-directional translation adjustment capability in the cavity 104 of the limiting carrier 101, so that the vehicle body 300 can be directly adjusted in horizontal posture, horizontal angle and lateral and longitudinal displacement. This eliminates the need for repeated hoisting and alignment of the vehicle, simplifies the operation and shortens the working time, and greatly improves the efficiency of posture adjustment.

[0034] In some embodiments, see Figure 3 , Figure 4 The limiting carrier 101 includes a disc body 110, which has a circular limiting baffle 105. A circular cavity 104 is formed inside the limiting baffle 105. The base 106 is circular, and the outer diameter of the base 106 is smaller than the inner diameter of the cavity 104. In this embodiment, both the cavity 104 and the base 106 are made circular, so that the top block 102 can have a larger translational adjustment interval with the limiting carrier 101 in multiple directions, thereby improving the vehicle body posture adjustment capability during use.

[0035] It is understandable that the cavity 104 of the limiting carrier 101 and the base 106 can also be configured as other shapes, such as polygons, ellipses, etc.

[0036] Further, see Figure 3 , Figure 4 The top pillar 107 extends upward along the centerline of the base 106, and its outer diameter is smaller than the inner diameter of the clearance hole 109. As a part that directly supports the vehicle body, the top pillar 107 has a positioning groove on its top, which can cooperate with the positioning ribs of the vehicle body to achieve a stable engagement. See also... Figure 6 The top pillar 107 can be adjusted in multiple directions within the range of the avoidance hole 109 along with the vehicle body.

[0037] In some embodiments, see Figure 3 , Figure 4 The bottom of the plate 110 is provided with a connecting seat 111 extending downward along the center line, and the top of the jack 200 is connected to the connecting seat 111. All the carrier components 100 are arranged along the center line to ensure the force balance during the lifting process of the jack 200 and improve the stability of the adjustment device.

[0038] The connecting seat 111 and the jack 200 can be connected by means of socketing, welding, etc. In some embodiments, the bottom of the connecting seat 111 is provided with a connecting hole 112 extending along the center line, and the connecting hole 112 is provided with internal threads. The top of the jack 200 is threadedly connected to the connecting hole 112. This embodiment effectively improves the connection stability between the jack 200 and the carrier assembly 100 by threading the output end of the jack 200 to the connecting seat 111, and also allows for the interchangeability of the carrier assembly 100 or the jack 200 to meet different needs.

[0039] In some embodiments, see Figure 3 , Figure 4 The limiting carrier 101 is provided with a guide groove 113 that penetrates the limiting baffle 105 and extends circumferentially. The base 106 is provided with a positioning arm 114 that extends outward through the guide groove 113. The limiting carrier 101 is provided with a positioning seat 115 on the outside of the guide groove 113. The positioning arm 114 and the positioning seat 115 are provided with pin holes 117 for inserting positioning pins 116. In this embodiment, before the vehicle body test attitude adjustment device lifts the vehicle body, the pin holes 117 of the positioning arm 114 and the positioning seat 115 are aligned and locked by the positioning pin 116 to ensure that the top block 102 remains in a constant position relative to the limiting carrier 101 during the lifting process of the jack 200, thus ensuring the stability of the vehicle body lifting process. When it is necessary to adjust the lateral and longitudinal displacement of the vehicle body, the positioning pin 116 can be removed to cancel the position locking of the limiting carrier 101 on the top block 102, further realizing the adjustment of the vehicle body's horizontal attitude, horizontal angle, and lateral and longitudinal displacement.

[0040] Further, see Figure 3 , Figure 4 The guide groove 113 includes a first guide groove and a second guide groove symmetrically arranged on the limiting carrier 101. The positioning arm 114 includes a first positioning arm and a second positioning arm symmetrically arranged on both sides of the base 106. The positioning seat 115 is symmetrically arranged on both sides of the limiting carrier 101 as a first positioning seat and a second positioning seat. In this embodiment, the guide groove 113, the positioning seat 115, and the positioning arm 114 adopt a symmetrical design to ensure that the top block 102 can be more fully locked with the limiting carrier 101, avoiding unilateral fixation failure due to the lower ball bearing 108 between the top block 102 and the limiting carrier 101.

[0041] In some embodiments, see Figure 3 The limiting carrier 101 has multiple lower ball mounting grooves 118 at the bottom of the cavity 104. The lower balls 108 are mounted in the lower ball mounting grooves 118 to constrain the position of each lower ball 108. The top of the lower ball 108 protrudes from the lower ball mounting groove 118 to support the bottom end face of the base 106.

[0042] In some embodiments, see Figure 3 , Figure 4 Multiple upper ball bearings 119 are provided between the limiting cover 103 and the base 106. The limiting cover 103 constrains the base 106 through the upper ball bearings 119, providing the base 106 with horizontal universal movement and upper limit in the cavity 104.

[0043] Further, see Figure 4 The bottom of the limiting cover 103 is provided with multiple upper ball mounting grooves 120. The upper balls 119 are installed in the upper ball mounting grooves 120 to constrain the position of each upper ball 119. The bottom of the upper ball 119 protrudes from the upper ball mounting groove 120 to support the top end face of the base 106.
