Description

Technical Field

[0001] This utility model relates to the field of tooling manufacturing technology, and specifically to a quick-change tooling connection device. Background Technology

[0002] In the field of mechanical manufacturing, tooling is fundamental to ensuring precision during parts manufacturing. Different parts are manufactured using different tooling. As project development progresses and the vehicle's lifespan approaches its end, the number of parts produced on that tooling gradually decreases, leading to a decline in equipment utilization at the workstation. Therefore, tooling switching is particularly important.

[0003] In the field of parts manufacturing, production lines need to frequently switch between different models and sizes of tooling parts. The emergence of quick-change devices can solve problems such as low equipment utilization and large equipment footprint. In the industry, the connection between traditional tooling and equipment base is mostly achieved by manually locking multiple sets of bolts, locating pins and pressure plates. Quick-change devices, when in use, will have problems such as long switching cycle time, poor repeatability, low effective load and low standardization, which have a significant impact on production.

[0004] Therefore, in order to meet the demand for "high cycle time, high precision, and low cost" quick-change in the production of parts manufacturing, there is an urgent need for a new type of quick-change connection device that does not require external power, has a compact structure, high repeatability, and low unit cost. Utility Model Content

[0005] Due to the aforementioned defects in the existing technology, this utility model provides a quick-change tooling connection device that can be matched with production tooling. It has a simple structure, low investment cost, high repeatability positioning accuracy, and convenient tooling switching, effectively solving the problems of low positioning accuracy and long switching cycle in the tooling switching process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tooling quick-change connection device includes a positioner connection device and a tooling connection device;

[0008] The positioner connecting device includes a main connecting plate, a positioner connecting plate, and a positioning connecting plate. The positioner connecting plate and the positioning connecting plate are located on both sides of the main connecting plate. The positioner connecting plate is provided with a plurality of positioner connecting device fixing bolts that fix the positioner connecting plate to the positioner rotating disk. The two ends of the main connecting plate are provided with rotating fixing components. The rotating fixing components include a mounting shaft, a rotating locking bolt, and a locking nut threadedly connected to the rotating locking bolt. The two ends of the main connecting plate have mounting grooves for the mounting shaft, and a mounting shaft is installed in the mounting grooves. One end of the rotating locking bolt is a sleeve ring, and the sleeve ring is fitted onto the mounting shaft. The rotating locking bolt can rotate around the mounting shaft.

[0009] The tooling connection device includes an L-shaped tooling connection plate and a tooling mounting plate that are connected to each other. The tooling connection plate has a positioning groove that matches the positioning connection plate, and both sides of the tooling connection plate have fixing grooves that match the rotating fixing components. The tooling mounting plate has tooling fixing holes for connecting the tooling. The tooling connection plate and the main connection plate have multiple pairs of toothed plate groups with different directions and matching each other on their opposite surfaces.

[0010] The tooling quick-change connection device of this utility model has a reasonable structural design. It can quickly fix the tooling connection device by using the positioning connection plate and rotating fixing component on the positioner connection device. At the same time, the multiple pairs of toothed plates with different directions between the positioner connection device and the tooling connection device can fully fix the two. It has good reliability and is easy to operate. It can realize the quick fixing and disassembly of the tooling and has great application prospects.

[0011] As a preferred technical solution:

[0012] As described above, in a tooling quick-change connection device, the positioner connecting plate and the positioning connecting plate are perpendicular to the main connecting plate.

[0013] As described above, in a quick-change tooling connection device, the width direction is perpendicular to the tooling mounting plate, and the width of the main connecting plate is smaller than the width of the tooling connecting plate, which ensures that the positioner connection device is located within the tooling connection device.

[0014] As described above, in a quick-change tooling connection device, the toothed plate assembly includes two matching toothed plates that are respectively mounted on a main connecting plate and a tooling connecting plate, and the exposed surface of the toothed plates has a serrated structure.

[0015] As described above, in a quick-change tooling connection device, there are three pairs of toothed plates. Two pairs of toothed plates are symmetrically installed on both sides of the main connecting plate, and the toothed plates of the two pairs of toothed plates are installed in the same direction. The other pair of toothed plates is installed in the middle of the main connecting plate, and the toothed plates of the toothed plate installed in the middle of the main connecting plate are installed in a direction perpendicular to the installation direction of the toothed plates of the two pairs of toothed plates.

[0016] As described above, in a quick-change tooling connection device, a locking force plate is also fitted onto the rotating locking bolt, and the locking force plate is located inside the locking nut. The locking force plate has a through hole that matches the rotating locking bolt. The presence of the locking force plate increases the locking contact surface and ensures the reliability of locking.

[0017] As described above, in a quick-change tooling connection device, the positioning connection plate has connecting bolt holes and is fixedly connected to the main connection plate by connecting bolts.

[0018] As described above, in a tooling quick-change connection device, the rotating disc of the positioner is mounted on the positioner.

[0019] As described above, in a tooling quick-change connection device, the main connecting plate and the positioner connecting plate are integrally formed parts;

[0020] The tooling connecting plate and the tooling mounting plate are integrally formed parts.

[0021] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

Detailed Implementation

[0032] The structure of this utility model will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the utility model.

[0033] Example 1

[0034] A quick-change tooling connection device, such as Figures 1-4 As shown, it includes a positioner connection device 1 and a tooling connection device 2;

[0035] The positioner connecting device 1 includes a main connecting plate 110, a positioner connecting plate 101, and a positioning connecting plate 102. The positioner connecting plate 101 and the positioning connecting plate 102 are located on both sides of the main connecting plate 110 and are perpendicular to the main connecting plate 110. The main connecting plate 110 and the positioner connecting plate 101 are integrally formed. The positioning connecting plate 102 has connecting bolt holes 111 and is fixedly connected to the main connecting plate 110 by connecting bolts. The positioner connecting plate 101 is provided with multiple positioner connecting device fixing bolts 100 for fixing the positioner connecting plate 101 to the positioner rotating disk 3. The positioner rotating disk 3 is mounted on the positioner 3A. The plate 110 has rotating fixing components at both ends. The rotating fixing components include a mounting shaft 109, a rotating locking bolt 106, and a locking nut 107 threadedly connected to the rotating locking bolt 106. A locking force plate 108 is also fitted on the rotating locking bolt 106 and is located inside the locking nut 107. The locking force plate 108 has a through hole that matches the rotating locking bolt 106. The main connecting plate 110 has mounting shaft mounting grooves 112 at both ends and the mounting shaft 109 is installed in the mounting shaft mounting grooves 112. One end of the rotating locking bolt 106 is a sleeve ring 1061, which is fitted on the mounting shaft 109. The rotating locking bolt 106 can rotate around the mounting shaft 109.

[0036] The tooling connection device 2 includes an L-shaped tooling connection plate 201 and a tooling mounting plate 205 that are interconnected. The tooling connection plate 201 and the tooling mounting plate 205 are integrally formed. The tooling connection plate 201 has a positioning groove 207 that matches the positioning connection plate 102, and both sides of the tooling connection plate 201 have fixing grooves 208 that match the rotating fixing components. The width direction is perpendicular to the arrangement direction of the tooling mounting plate 205. The width of the main connection plate 110 is smaller than the width of the tooling connection plate 205. The mounting plate 205 has tooling fixing holes 206 for connecting tooling 2A. The tooling connecting plate 201 and the main connecting plate 110 have three pairs of toothed plate groups with different directions and matching each other. Each toothed plate group includes two matching toothed plates that are respectively installed on the main connecting plate 110 and the tooling connecting plate 201. The exposed surface of the toothed plate has a sawtooth structure. There are three pairs of toothed plate groups. Two pairs of toothed plate groups are symmetrically installed on both sides of the main connecting plate 110 and the toothed plates of the two pairs of toothed plate groups have the same installation direction (toothed plate I 103 and toothed plate VI 204, toothed plate III 105 and toothed plate IV 202).

[0037] In practical applications, the positioner connecting device 1 is first connected to the positioner rotating disk 3 without periodic disassembly. The tooling connecting device 2 and the positioner connecting device 1 are interlocked by toothed plates with three different installation directions to achieve stable flat placement of the tooling. At the same time, the rotating locking bolt 106 is opened to ensure that the tooling connecting device 2 and the positioner connecting device 1 are fully clamped and do not loosen. The positioner connecting device 1 and the tooling connecting device 2 are used in pairs.

[0038] The toothed plates in the tooling connection device and the positioner connection device are interlocked and locked by rotating bolts. The tooling connection device can be effectively fixedly connected to the tooling or fixture, and the positioner connection device can be effectively fixedly connected to the disc of the positioner. This structure can bear several tons of tooling and will not loosen even during tooling displacement.

[0039] In summary, this application provides a quick-change tooling connection device with a simple overall structure, low investment cost, and effective reduction in manufacturing costs. By interlocking between toothed plates and tightening with bolts, it can reduce the switching cycle between different tooling, improve the repeatability of positioning after tooling switching, and reduce the labor intensity of the switching process, making it highly promising for application.
