Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a quick positioning and clamping mechanism for an automobile painting skid. Background Technology

[0002] In automotive painting production lines, skid conveyors are key devices for transporting car bodies, and their performance directly affects painting efficiency and product quality. Traditional painting skid conveyors typically consist of a two-layer structure: an upper skid that carries the car body and a lower roller bed that drives the skid.

[0003] Currently, most positioning and clamping mechanisms for skid positioning adopt mechanical clamping methods. Mechanical clamping methods transmit force through mechanical components to directly achieve positioning and fixation. Their structure is simple and relies on physical contact to generate clamping force. However, the clamping action of traditional mechanical clamping mechanisms mainly relies on manual or semi-automatic operation, which has a slow response speed and is difficult to adapt to high-speed production lines. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a quick positioning and clamping mechanism for automotive painting skids, including a clamping module and a power module. The power module drives the clamping module to move, so as to clamp or release the positioning point of the skid.

[0005] The clamping module includes:

[0006] Fixing part;

[0007] The movable plate has two sets, which are arranged crosswise. One end of each set of movable plates is pivotally connected to the fixed part, and the inner side of the other end is removably fitted with a clamping block. The inner side of the clamping block matches the clamping point. The movable plate is driven by a power module to move around its pivot connection end with the fixed part, so that the two sets of clamping blocks move closer or further apart.

[0008] This invention utilizes a power module to drive the opening and closing of movable plates, enabling rapid clamping or releasing of the skid positioning points. This improves the stability and consistency of the skid during the painting process, reducing painting defects and rework rates. By arranging two sets of movable plates in a cross configuration, it can more flexibly adapt to positioning points of different shapes and sizes. The mechanism is simple in design and compact in structure, reducing manufacturing and maintenance costs.

[0009] Furthermore, a waist-shaped hole is provided at the intersection of the two sets of movable plates;

[0010] The power module includes:

[0011] Power unit;

[0012] An eccentric block, one end of which is connected to a power device, drives the eccentric block to rotate around one end, and the plane in which the eccentric block rotates is perpendicular to the axis of rotation of the eccentric block itself.

[0013] A limiting part is fixedly installed at the end of the eccentric block away from the power device, and the limiting part is inserted into the waist-shaped hole.

[0014] Furthermore, a roller is fitted on the outside of the limiting part to maintain a relative rotating drum.

[0015] The rotation of the eccentric block is driven by the power unit, which in turn drives the limiting part installed on the end of the eccentric block away from the power unit to rotate, thereby driving the linear opening and closing motion of the movable plate, which improves the response speed. Since the limiting part is inserted into the waist-shaped hole, the limiting part always moves within the range of the waist-shaped hole, so that the movable plate opens and closes within a limited range, thereby avoiding rigid collisions of the mechanism when the power unit malfunctions and reducing the risk of equipment damage.

[0016] Furthermore, the power module also includes a reducer, the input shaft of which is connected to the output shaft of the power unit, and the output shaft of the reducer is connected to an eccentric block.

[0017] The reducer has torque regulation, vibration suppression and multi-load adaptability, thereby improving the stability and adaptability of the entire clamping mechanism.

[0018] Furthermore, a limit sensing plate is provided at the end of the limiting part away from the eccentric block;

[0019] The positioning and clamping mechanism also includes a limiting device, which is disposed on one side of the limiting sensing plate and includes a limiting sensor.

[0020] Furthermore, the limiting device also includes a connecting part on which the limiting sensor is removably mounted.

[0021] Furthermore, the connecting portion has a T-shaped groove;

[0022] The limiting device further includes:

[0023] The second limiting plate is disposed in the T-groove;

[0024] The first limiting plate, on which the limiting sensor is fixed, is arranged parallel to the second limiting plate on the outer side of the T-shape;

[0025] A fixing bolt is used to sequentially pass through the first limiting plate, the slot of the T-shaped groove, and the second limiting plate, thereby keeping the first limiting plate, the second limiting plate, and the connecting part relatively fixed.

[0026] By detecting the maximum travel position of the limit sensing plate using a limit sensor, the endpoint position of the clamping module (such as clamping in place or fully released) can be indirectly detected, thus avoiding clamping overload or positioning failure caused by mechanical errors or power deviations. The limit sensor's position can be finely adjusted by the parallel arrangement of the first and second limit plates, combined with the fixing method of T-slots and fixing bolts.

[0027] This utility model has the following advantages:

[0028] This invention utilizes a power module to drive the clamping module, enabling rapid clamping or releasing of the skid positioning points. This improves the stability and consistency of the skid during the painting process, reducing painting defects and rework rates. By arranging two sets of movable plates in a cross configuration, it can more flexibly adapt to positioning points of different shapes and sizes. The mechanism is simple in design and compact in structure, reducing manufacturing and maintenance costs. Attached Figure Description

[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0042] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0043] As described in the background section, most current positioning and clamping mechanisms for positioning skids use mechanical clamping methods. Mechanical clamping methods transmit force through mechanical components (such as bolts, levers, cams, etc.) to directly achieve positioning and fixation. They have a simple structure and rely on physical contact to generate clamping force. However, the clamping action of traditional mechanical clamping mechanisms mainly relies on manual or semi-automatic operation, which has a slow response speed and is difficult to adapt to high-speed production lines.

[0044] Example 1:

[0045] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a quick positioning and clamping mechanism for automotive painting skids, such as... Figure 1 As shown, the quick positioning and clamping mechanism includes a clamping module 40 and a power module 30. The power module drives the clamping module to move, so as to clamp or release the positioning point of the skid.

[0046] like Figure 3 As shown, the clamping module includes:

[0047] Fixing part 41;

[0048] The movable plate 42 has two sets, which are arranged crosswise. One end of each set of movable plates is pivotally connected to the fixed part, and the inner side of the other end is removably fitted with a clamping block 44. The inner side of the clamping block matches the clamping point. The movable plate is driven by the power module to move around its pivot connection end with the fixed part, so that the two sets of clamping blocks move closer or further apart.

[0049] This embodiment uses a power module to drive the movable plate to move around its pivot connection with the fixed part, thereby realizing the opening and closing movement of the movable plate, which in turn clamps and fixes the skid positioning point, improving the stability and consistency of the skid during the painting process and reducing painting defects and rework rates. By arranging the two sets of movable plates in a cross configuration, it can more flexibly adapt to positioning points of different shapes and sizes. The mechanism has a simple design, compact structure, and fast response speed, reducing manufacturing and maintenance costs. In addition, as... Figure 1 As shown, the quick positioning and clamping mechanism may further include a mounting bracket 10, on which both the power module and the clamping module can be fixedly mounted, such as... Figure 6 As shown, the quick positioning and clamping mechanism can be fixedly installed at a designated position on the roller bed. When the skid moves to the preset position under the action of the roller bed, the power module drives the movable plate to move so that the clamping block positions and fixes the positioning point of the skid, thereby fixing the skid in the preset position.

[0050] In this embodiment, the clamping block can be adaptively designed and replaced according to the shape of the positioning point.

[0051] For example, such as Figure 3 As shown, a waist-shaped hole 43 is provided at the intersection of the two sets of movable plates;

[0052] like Figure 2 As shown, the power module includes:

[0053] Power unit 31;

[0054] Eccentric block 33, one end of which is connected to a power device, and the power device drives the eccentric block to rotate around one end of it. The plane in which the eccentric block rotates is perpendicular to the axis of rotation of the eccentric block itself.

[0055] The limiting part 36 is fixedly installed at the end of the eccentric block away from the power device, and the limiting part is inserted into the waist-shaped hole.

[0056] For example, a roller 34 is fitted on the outside of the limiting part to maintain a relative rotating cylinder.

[0057] In this embodiment, the rotation of the eccentric block is driven by a power device, which in turn drives the rotation of the limiting part installed on the end of the eccentric block away from the power device. This, in turn, drives the movable plate to open and close linearly. The design of the oblong hole allows the limiting part to slide in a specific direction within the hole to accommodate the multi-directional displacement when the eccentric block rotates, increasing the movement flexibility of the movable plate and making power transmission more efficient and response faster. Since the limiting part is inserted into the oblong hole, it always moves within the range of the oblong hole, thus allowing the movable plate to open and close within a limited range. This avoids rigid collisions of the mechanism when the power device malfunctions, reducing the risk of equipment damage. In addition, a roller that rotates relative to the limiting part is provided on the outside of the limiting part. When the limiting part moves within the oblong hole, the roller rotates relative to the limiting part, that is, the roller rolls within the oblong hole along the movement direction of the limiting part, thereby reducing the movement friction of the power module within the oblong hole and reducing movement wear. In this embodiment, the power device can be a motor, including but not limited to a servo motor, a stepper motor, or other devices capable of rotating the eccentric block.

[0058] In addition, the power module may also include a reducer 32, the input shaft of which is connected to the output shaft of the power device, and the output shaft of the reducer is connected to the eccentric block.

[0059] The reducer has torque regulation, vibration suppression and multi-load adaptability, thereby improving the stability and adaptability of the entire clamping mechanism.

[0060] For example, such as Figure 2 As shown, a limit sensing plate 35 can also be provided at the end of the limit part away from the eccentric block;

[0061] The positioning and clamping mechanism also includes a limiting device 20, which is disposed on one side of the limiting sensing plate. The limiting device can be fixedly installed on the mounting frame.

[0062] like Figure 4 As shown, the limiting device includes a limiting sensor 21.

[0063] The maximum stroke position of the limit sensing plate is detected by the limit sensor, thereby indirectly detecting the end position of the clamping module (such as clamping in place or fully released state), so as to avoid clamping overload or positioning failure caused by mechanical error or power deviation.

[0064] In this embodiment, the limiting device may further include a connecting part 23, on which the limiting sensor is removably mounted.

[0065] For example, such as Figure 4 , 5 As shown, the connecting part has a T-shaped groove;

[0066] The limiting device further includes:

[0067] The second limiting plate 25 is disposed in the T-shaped groove;

[0068] The first limiting plate 22 is used to fix the limiting sensor. The first limiting plate is arranged parallel to the second limiting plate on the outer side of the T-shape.

[0069] The fixing bolt 24 passes through the first limiting plate, the slot of the T-shaped groove, and the second limiting plate in sequence, and keeps the first limiting plate, the second limiting plate, and the connecting part relatively fixed by the fixing bolt.

[0070] This embodiment achieves fine-tuning of the sensor's position by using the parallel arrangement of the first and second limiting plates, combined with the T-slot and fixing bolts. For example, by loosening the fixing bolts, the connecting part of the two sets of limiting plates can be loosened, allowing the limiting sensor to move along the T-slot under external force. Tightening the fixing bolts will cause the first and second limiting plates to gradually move closer together until the connecting part is clamped, thereby achieving relative fixation between the limiting sensor and the connecting part.

[0071] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
