Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a device for quickly switching clamps and picking up parts. Background Technology

[0002] The current storage and switching of clamps used for welding bus bodies utilizes a combination of overhead cranes and forklifts for transfer and switching, such as... Figure 1 As shown, the fixture and platform are integrated, making them bulky during transport and preventing quick switching between fixtures for use. Currently, the processed parts are removed manually with a pry bar, which is prone to deformation and has low removal efficiency. Summary of the Invention

[0003] To address the problems of inconvenient transport due to the integral design of existing clamps and platforms and the risk of deformation during manual handling, this invention provides a device for quickly switching between clamps and handling components. By separating the universal platform and modular clamps, only the modular clamps need to be transported during transport, making transport convenient. Furthermore, by setting a handling device on the universal platform, it prevents deformation of components subjected to uneven force when manually prying them with a pry bar.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A device for quickly switching clamps and picking up parts includes a universal platform and multiple modular clamps. The multiple modular clamps are arranged sequentially on the universal platform, and the modular clamps are detachably connected to the universal platform. Each modular clamp is provided with lifting lugs on both sides.

[0006] The universal platform is equipped with clamping devices on both sides to fix the modular fixture to the universal platform, and a part-removing device is provided on the upper part of the modular fixture.

[0007] Furthermore, the universal platform includes multiple fixture placement areas, each equipped with a modular fixture, and each fixture placement area is equipped with a positioning detection device, a clamping device, and a part removal device. The universal platform has multiple fixture placement areas, allowing for the placement of different numbers of modular fixtures according to the needs of different vehicle models, making it convenient to use.

[0008] Furthermore, the positioning and detection device includes positioning pins and detection reference points. Both the positioning pins and detection reference points are fixed to both sides of the universal platform. The modular fixture is provided with positioning holes corresponding to the positioning pins, and reference holes corresponding to the detection reference points. The positioning pins and positioning holes enable rapid positioning during the assembly of the modular fixture, improving assembly efficiency. The detection reference points and reference holes allow the installed modular fixture to be connected to the detection reference points via a testing instrument to detect the installation accuracy of the modular fixture.

[0009] Furthermore, the modular fixture comprises multiple units, each including a base plate, multiple clamps, and multiple positioning blocks. The base plate is mounted on a universal platform, and the clamps and positioning blocks are all inserted and fixed to the base plate. This allows for layout according to the different component shapes required by various vehicle models.

[0010] Furthermore, the clamps and positioning blocks of the modular fixture can be customized to fit the vehicle's structure.

[0011] Furthermore, reinforcing beams are provided around the top surface of the base plate, and multiple lifting lugs are provided on each modular component. The lifting lugs are symmetrically fixed to the modular components, and the sides of the lifting lugs are fixed to the reinforcing beams. The reinforcing beams improve the strength of the base plate and the lifting lugs, extending their service life.

[0012] Furthermore, the clamping device includes a telescopic component, a connecting component, and a clamping component. The connecting component is fixed to the side of the universal platform, the fixed end of the telescopic component is fixed to the connecting component, and the clamping component is hinged to the upper part of the telescopic end of the telescopic component. The modular fixture can be detachably fixed to the universal platform by the clamping device, which is convenient for hoisting and transportation.

[0013] Furthermore, the clamping member is provided with a handle. The handle allows the clamping member to be tightened and secured to the modular fixture and universal platform by rotating the handle without using the telescopic member.

[0014] Furthermore, the part-retrieving device includes two sets of sliding telescopic devices and a part-retrieving tool. The sliding telescopic devices are symmetrically arranged on both sides of the universal platform, and the part-retrieving tool is located on the upper part of the modular fixture. The part-retrieving tool has a rod-shaped structure, and its two ends are respectively connected to the sliding telescopic devices. The part-retrieving device avoids deformation of components caused by uneven force during manual part-retrieving.

[0015] Furthermore, each set of the sliding telescopic device includes a fixed component, a slide rail, and a second telescopic component. The fixed component is fixed to the side wall of the universal platform, the slide rail is fixed to the fixed component, the second telescopic component is slidably connected to the slide rail, and the end of the retrieval device is fixed to the top of the second telescopic component. The fixed component and the slide rail move the second telescopic component and the retrieval device to the position of each component to retrieve the component. The second telescopic component moves the retrieval device upward to push the component out, avoiding uneven force during manual retrieval that could cause component deformation.

[0016] The beneficial effects of this utility model through the above technical solution are:

[0017] This invention detachably connects a universal platform and modular clamps, facilitating transportation by requiring only the transfer of the modular clamps during transport. The universal platform features multiple clamp placement areas, allowing for the placement of varying numbers of modular clamps to suit different vehicle models, enhancing ease of use. The clamps and positioning blocks are plug-in fixed, accommodating different component shapes according to vehicle models. The detachable connection between the universal platform and modular clamps, achieved through a positioning detection device and a clamping device, ensures convenient fixation and prevents displacement. A part-removal device within the clamp placement area ensures even force distribution on the part during removal, preventing deformation caused by uneven force. Attached Figure Description

[0028] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0029] like Figures 2-9 As shown, a device for quickly switching clamps and picking up parts includes a universal platform 1 and multiple modular clamps 2. The modular clamps 2 are set on the universal platform 1, and different numbers of modular clamps 2 can be placed on the universal platform 1 according to the needs of different vehicle models.

[0030] The universal platform 1 includes multiple clamp placement areas 11, each of which can be equipped with a modular clamp 2. The modular clamp 2 includes a base plate 21, multiple clamps 22, and multiple positioning blocks 23. The base plate 21 is mounted on the universal platform 1 and is detachably connected to it. Multiple lifting lugs 5 are provided on the base plate 21, symmetrically fixed to both sides of the base plate 21. In this embodiment, there are four lifting lugs 5, symmetrically arranged in pairs at the ends of both sides of the base plate 21. To improve the strength of the base plate 21 and the lifting lugs 5, multiple reinforcing beams 24 are fixed on the base plate 21, forming a frame structure between the lifting lugs 5. The reinforcing beams 24 adjacent to the lifting lugs 5 are fixedly connected to them. The clamps 22 and positioning blocks 23 are located inside the frame structure, and both are inserted and fixed to the base plate 21. The clamps 22 and positioning blocks 23 of the modular fixture 2 can be arranged in different ways for different vehicle models.

[0031] Each fixture placement area 11 is also equipped with a positioning detection device, a clamping device 3, and a part removal device 4. The positioning detection device includes positioning pins 12 and detection reference points 13. There are multiple detection reference points 13, and each detection reference point has a columnar interface. When precision testing is required, the testing instrument connects to the interface of the detection reference point. In this embodiment, there are four detection reference points 13, which are symmetrically fixed on both sides of the fixture placement area 11 in pairs. There are multiple positioning pins 12, which are fixed at intervals between two detection reference points 13 on the same side. The base plate 21 has reference holes 26 corresponding to the detection reference points 13. The reference holes 26 are located between the lifting lug 5 and the side of the base plate 21. The detection reference points 13 can detect whether the modular fixture 2 is offset after it is hoisted to the fixture placement area 11 of the general platform 1 by connecting the detection instrument to the detection reference points 13. In this embodiment, the detection instrument is a detection instrument capable of detecting the accuracy of a three-coordinate measuring machine. The base plate 21 has a positioning hole 25 corresponding to the positioning pin 12, and the positioning hole 25 is located between the reinforcing beam 24 and the edge of the base plate 21. The positioning pin 12 and the positioning hole 25 enable the base plate 21 to be quickly connected to the fixture placement area 11 of the universal platform 1.

[0032] Each fixture placement area 11 is equipped with multiple clamping devices 3, which fix the modular fixture 2 to the universal platform 1. In this embodiment, there are four clamping devices 3, which are symmetrically fixed to the two ends of the fixture placement area 11 in pairs. Each clamping device 3 includes a telescopic member 31, a connecting member 32, and a clamping member 33. The connecting member 32 is fixed to the side of the universal platform 1, the telescopic member 31 is fixed to the connecting member 32, and the clamping member 33 is hinged to the top of the telescopic member 31, allowing the telescopic member 31 to move the clamping member 33 up and down.

[0033] To increase the reliability of the clamping device 3, the clamping member 33 is also provided with a handle 34. The handle 34 is connected to the connector 32 by a pin. The lower part of the clamping member 33 has a groove, and the handle 34 is provided with a column. The column is inserted into the groove of the clamping member 33. When the telescopic member is not needed, by rotating the handle 34, the column on the handle 34 pushes the clamping member 33 to flip downward, so that the clamping member 33 clamps and fixes the universal platform 1 and the modular clamp 2.

[0034] The clamping area 11 has two picking devices 4 on both sides, which are located between two clamping devices 3. Each picking device 4 includes two sets of sliding telescopic devices and a picking tool 44. The sliding telescopic devices are symmetrically arranged on both sides of the universal platform 1. Specifically, each sliding telescopic device includes a fixing member 41, a slide rail 42, and a second telescopic member 43. There are multiple fixing members 41, which are spaced apart between the two clamping devices 3 on the same side. The fixing members 41 are fixedly connected to the universal platform 1. The slide rail 42 is mounted on top of the multiple fixing members 41, and a connecting seat 45 is provided on the slide rail 42. The connecting seat 45 is slidably connected to the slide rail 42, and the second telescopic member 43 is fixed to the connecting seat 45. The picking tool 44 is located on the upper part of the modular clamp 2 and is connected to the second telescopic member 43. The second telescopic member 43 drives the picking tool 44 to move up and down. The two ends of the retrieval device 44 are respectively engaged with the top of the telescopic component 43. Specifically, the retrieval device 44 is a rod, and the top of the telescopic component 43 is fixed with a fixing seat 46. The top of the fixing seat 46 is provided with a through groove corresponding to the end of the retrieval device 44, and the end of the retrieval device 44 is set in the through groove.

[0035] To improve the stability of the connection between the modular fixture 2 and the universal platform 1, a plurality of fixing holes 14 are provided on the base plate 21. The plurality of fixing holes 14 are arranged in a matrix. The universal platform 1 is provided with bolt holes 27 corresponding to the fixing holes 14. The fixing holes 14 and the bolt holes 27 are fixedly connected by bolts.

[0036] In this embodiment, both the first telescopic component 31 and the second telescopic component 43 are cylinders. Both are connected to a control panel, which controls their movement. Any commercially available control panel capable of controlling cylinder movement is suitable for this application; in this example, the control panel is a PLC controller.

[0037] When in use, the number of modular clamps 2 is selected according to the vehicle model requirements, and the arrangement order of the clamps 22 and positioning blocks 23 on the modular clamps 2 is adjusted according to the shape requirements of the vehicle model. The modular clamps 2 are transported to the clamp placement area 11 above the universal platform 1 by lifting the lifting lugs 5 on the modular clamps 2 with a crane. After the detection reference point 13 is aligned with the reference hole 26 on the base plate 21, it is lowered. The positioning pin 12 passes through the positioning hole 25, and the modular clamps 2 are placed in the clamp placement area 11 of the universal platform 1. The telescopic component 31 is controlled to move downward through the control panel. The telescopic component 31 drives the clamping component 33 to move downward. The clamping component 33 moves to the top of the base plate 21 and contacts the base plate 21, so that the base plate 21 is pressed and fixed to the universal platform 1, and the modular clamps 2 are fixed to the universal platform 1. The fixing hole 14 and the bolt hole 27 are fixedly connected by bolts to further fix the modular clamps 2 to the universal platform 1 and improve the connection stability. The two ends of the part picker 44 are positioned within the through slots of the top fixing seat 46 of the telescopic component 2 43 on both sides of the fixture placement area 11. The part to be processed is placed on the fixing block, at which point the part picker 44 is located below the part to be processed; the clamp 22 then fixes the part for processing. After processing is completed, the clamp 22 is released, and the control panel controls the telescopic component 2 43 to move upward. The telescopic component 2 43 drives the part picker 44 to move upward, and the part picker 44 pushes out the processed part set in the positioning block 23, thus achieving part removal. This avoids the problem of uneven force and deformation caused by manually prying the part for removal.
