Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling, specifically to a compatible tooling trolley. Background Technology
[0002] The assembly of the subframe and the mounting is a key part of the automotive chassis design. It supports the powertrain and suspension system. As a transitional structure between the body and the suspension / powertrain, the subframe supports the weight of these components through the mounting and transfers the load to the body. The flexible connection of the mounting reduces local stress concentration and avoids fatigue cracking of the body or subframe caused by rigid connections. It also has the function of isolating vibration and noise.
[0003] Because different vehicle models have different chassis designs, the positions of the positioning holes and support surfaces are not interchangeable. Therefore, different tooling is required to position the workpiece during the assembly of the subframe and the suspension.
[0004] During the production process, the corresponding tooling needs to be changed when producing chassis for different car models. However, changing tooling in automated production will significantly reduce production efficiency. Therefore, it is necessary to design tooling for automated production that is compatible with different car models. Utility Model Content
[0005] The purpose of this invention is to provide a compatible tooling trolley that can produce workpieces of different models in a compatible manner.
[0006] To achieve the above objectives, this utility model provides a compatible tooling trolley, including a conveying base plate, a positioning pin fixedly connected to the conveying base plate, support blocks, and a switching support. The support blocks are configured in multiple sets, each set having a different height. The support position of the positioning pin is adjustable. The switching support is equipped with a switching device, which allows the height of the support surface of the switching support to be changed.
[0007] Preferably, the positioning pin includes a first fixing rod fixedly connected to the conveying base plate and a support pin detachably connected to the first fixing rod. The support pin includes a pin body and a connecting plate fixedly connected to the pin body for supporting the pin body.
[0008] Preferably, multiple support pins are provided, and the pin heights of the multiple support pins are different.
[0009] Preferably, the first fixing rod is provided with a mounting hole, and the support pin is detachably connected to the first fixing rod through the mounting hole.
[0010] Preferably, the mounting hole is a through hole.
[0011] Preferably, the switching support includes a second fixed rod and a sleeve sleeve fitted inside the second fixed rod, with the support surface located at the top of the sleeve sleeve, and the sleeve sleeve being able to move up and down within the second fixed rod.
[0012] Preferably, the switching support further includes an adjusting rod fixedly connected to the sleeve column. The surface of the second fixing rod is provided with at least two stop positions, and the height of the multiple stop positions is set differently. The adjusting rod cooperates with the stop positions to adjust the support surface.
[0013] Preferably, the second fixed rod is cylindrical, and multiple stop positions are connected by a sliding channel, allowing the adjusting rod to slide within the sliding channel.
[0014] Preferably, a marker is provided near the stop position.
[0015] According to the above technical solution, the positioning pin, support block and switching support of this utility model are all fixedly connected to the conveying base plate, and the conveying base plate can play a supporting and fixing role for these positioning devices; the conveying base plate can also be connected to the conveying equipment to achieve the purpose of moving the workpiece located on the tooling trolley.
[0016] The support blocks are set in multiple groups, and different groups of support blocks can support workpieces of different models. The support blocks in different groups are set at different heights. According to the actual production needs, the support blocks in different groups also need to be distributed in different positions on the conveyor base plate so as to avoid interference between the support blocks and the workpiece through this staggered arrangement along the height direction.
[0017] The support blocks are set to different heights for different workpieces, thus the heights of different workpieces are also different. When the tooling trolley needs to accommodate multiple workpieces, these workpieces occupy more surface area on the conveyor base plate 1, and the mechanisms fixed on the conveyor base plate may interfere with the workpieces. Therefore, in order to accommodate more workpieces, it is necessary to avoid setting too many fixing mechanisms on the conveyor base plate. Hence, the tooling trolley is configured with locating pins and switching supports that have compatibility functions.
[0018] The locating pin is designed with adjustable height and position. To meet the usage requirements of different workpieces, the position of the locating pin needs to be set differently. At the same time, to match the support height of the support block for the workpiece, the height of the locating pin also needs to be adapted to the actual height of the workpiece.
[0019] The height of the locating pin is adjustable. In one embodiment, the height of the locating pin can be adjusted by means of a lead screw and nut. The bottom of the locating pin is provided with a nut, and the pin body is fixedly connected to the top of the lead screw. By rotating the lead screw, the height of the pin body at the top of the lead screw can be adjusted to meet the height requirements of the workpiece for the locating pin.
[0020] The relative position of the positioning pin on the transport base plate also needs to be adjustable. In one embodiment, the pin body is connected to the lead screw via a connecting plate. The connecting plate is configured to fit a square outer cylinder and a square inner cylinder. The square inner cylinder is fitted inside the square outer cylinder and can slide and rise within the square outer cylinder. A positioning hole is provided on the square outer cylinder, which engages with a locking pin. By tightening the locking pin, the square inner cylinder and the square outer cylinder are fixed together.
[0021] The top of the switching support is equipped with a support surface, the height of which can be adjusted via a switching device. Similar to the positioning pin, the switching support can also adjust the position of the support surface by incorporating a lifting mechanism and a telescopic mechanism.
[0022] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0037] In this utility model, unless otherwise stated, directional words such as "nearby," "inside," and "top" included in the terminology only represent the location of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.
[0038] See Figure 1 The aforementioned compatible tooling trolley includes a conveying base plate 1, a positioning pin 2 fixedly connected to the conveying base plate 1, a support block 3, and a switching support 4. The support block 3 is configured in multiple sets, each set having a different height. The support position of the positioning pin 2 is adjustable. The switching support 4 is equipped with a switching device, which can change the height of the support surface 43 of the switching support 4.
[0039] Through the implementation of the above technical solution, the positioning pin 2, the support block 3 and the switching support 4 are all fixedly connected to the conveying base plate 1, and the conveying base plate 1 can play a supporting and fixing role for these positioning devices; the conveying base plate 1 can also be connected to the conveying equipment to achieve the purpose of moving the workpiece located on the tooling trolley.
[0040] The support blocks 3 are set in multiple groups. Different groups of support blocks 3 can support workpieces of different models. The support blocks 3 of different groups are set at different heights. According to the actual production needs, the support blocks 3 of different groups also need to be distributed at different positions on the conveyor base plate 1 so as to avoid interference between the support blocks 3 and the workpiece through this staggered arrangement along the height direction.
[0041] The support block 3 is set to different heights for different workpieces, therefore the heights of different workpieces are also different. When the tooling trolley needs to accommodate multiple workpieces, these workpieces occupy more surface area on the conveyor base plate 1, leaving less space for support structures such as the support block 3. The support structures fixed on the conveyor base plate 1 may interfere with the workpieces. Therefore, in order to accommodate more workpieces, it is necessary to avoid setting too many fixing mechanisms on the conveyor base plate 1. Hence, the tooling trolley sets the positioning pin 2 and the switching support 4 as support structures with compatibility functions.
[0042] The positioning pin 2 is configured as a mechanism with adjustable height and position. In order to meet the usage requirements of different workpieces, the position of the positioning pin 2 needs to be set differently. At the same time, in order to match the support height of the support block 3 for the workpiece, the height of the positioning pin 2 also needs to be adapted to the actual height of the workpiece.
[0043] The height of the positioning pin 2 is adjustable. In one embodiment, the height of the positioning pin 2 can be adjusted by means of a screw and nut. The bottom of the positioning pin 2 is provided with a nut, and the pin body 22 is fixedly connected to the top of the screw. By rotating the screw, the height of the pin body 22 at the top of the screw can be adjusted to meet the height requirements of the workpiece for the positioning pin 2.
[0044] The relative position of the positioning pin 2 on the transport base plate also needs to be adjustable. In one embodiment, the pin body 22 is connected to the lead screw via a connecting plate 23. The connection position of the connecting plate 23 and the lead screw is set in a manner where a square outer cylinder and a square inner cylinder cooperate. By pulling the connecting plate 23, a sliding connection between the connecting plate 23 and the lead screw can be achieved. A positioning hole is provided on the square outer cylinder, which cooperates with a locking pin. The locking pin is used to fix the relative position of the connecting plate 23 and the lead screw.
[0045] The top of the switching support 4 is provided with a support surface 43, and the height of the support surface 43 can be adjusted by the switching device. Similar to the positioning pin 2, the switching support 4 can also adjust the support position and support height of the support surface 43 by setting up a lifting mechanism and a telescopic mechanism.
[0046] In this embodiment, preferably, the positioning pin 2 includes a first fixing rod 21 fixedly connected to the conveying base plate 1 and a support pin detachably connected to the first fixing rod 21. The support pin includes a pin body 22 and a connecting plate 23 fixedly connected to the pin body 22 for supporting the pin body 22.
[0047] When it is necessary to produce workpieces for different car models, the positioning pin 2 can be switched by changing different support pins to adapt to the production of new workpieces.
[0048] Preferably, the height of the first fixing rod 21 is set low so that the first fixing rod 21 will not interfere with any workpiece on the tooling trolley, thereby enabling the tooling trolley to accommodate more different workpieces.
[0049] In this embodiment, preferably, multiple support pins are provided, and the height of the pin body 22 of the multiple support pins and the relative position of the pin body 22 with the first fixing rod 21 are different.
[0050] The height of the pin 22, which matches the height of the first fixing rod 21, is the height of the positioning pin 2. This height needs to be adapted to the height of the workpiece.
[0051] In one embodiment, different pins 22 with different heights can be set. When different workpieces need to be produced, different pins 22 can be selected for installation to meet production requirements.
[0052] In one embodiment, the pin 22 is a single unit, and a height adjustment block is provided at the connection position between the pin 22 and the connecting plate 23. The height of the pin 22 can be adjusted by using different height adjustment blocks. The pin 22 and the connecting plate 23 are detachably connected.
[0053] The relative positions between the pin 22 and the first fixing rod 21 are set differently to adapt to the positions of the positioning holes of different workpieces.
[0054] In one embodiment, the connecting plate 23 is configured with different shapes. The connecting plate 23 is configured as L-shaped. By reasonably setting the length of the connecting plate 23 in the X and Y directions, the position of the pin 22 can be adjusted.
[0055] In this embodiment, preferably, the first fixing rod 21 is provided with a mounting hole 211, and the support pin is detachably connected to the first fixing rod 21 through the mounting hole 211.
[0056] Inserting the support pin into the mounting hole 211 connects the connecting plate 23 to the first fixing rod 21. Preferably, to ensure the reliability of the relative position between the support pin and the first fixing rod 21, the mounting hole 211 can be set as a square hole. The support pin cannot rotate within the square hole, thus limiting the support pin's position. Alternatively, a locking hole that mates with the locking pin 212 can be provided on the side of the mounting hole 211, and a corresponding locking hole is also provided on the support pin. The cooperation between the locking pin 212 and the locking hole ensures reliable positioning of the support pin and the mounting hole 211.
[0057] In this embodiment, preferably, the mounting hole 211 is a through hole. By making the mounting hole 211 a through hole, the support pin can be inserted through both ends of the through hole, thereby giving the pin body 22 a larger coverage area.
[0058] In this embodiment, preferably, the switching support 4 includes a second fixed rod 41 and a sleeve 42 sleeved in the second fixed rod 41, with the support surface 43 located at the top of the sleeve 42, and the sleeve 42 being able to move up and down within the second fixed rod 41.
[0059] The height of the support surface 43 can be adjusted by raising and lowering the sleeve column 42, thereby adapting to the height of different workpieces.
[0060] The sleeve 42 can be raised and lowered within the second fixed rod 41 by manually pulling the sleeve 42. In one embodiment, a locking hole is provided on the second fixed rod 41, and the surface of the sleeve 42 has a mark corresponding to the vehicle model. When it is necessary to produce a workpiece of a certain vehicle model, it is only necessary to manually pull the sleeve 42 until the corresponding mark appears, then align the mark with the upper end face of the second fixed rod 41, and then tighten the locking pin that cooperates with the locking hole.
[0061] In this embodiment, preferably, the switching support 4 further includes an adjusting rod 44 fixedly connected to the sleeve column 42, and the surface of the second fixing rod 41 is provided with at least two stop positions 45. The heights of the multiple stop positions 45 are set differently, and the adjusting rod 44 cooperates with the stop positions 45 to adjust the support surface 43.
[0062] By setting a stop position 45 and an adjusting rod 44 that cooperates with the stop position 45, the height of the sleeve 42 can be adjusted, and the height of the sleeve 42 after adjustment can be fixed.
[0063] A channel for the adjustment rod 44 to pass through is provided on the surface of the second fixed rod 41. Multiple stop positions 45 are provided at different heights along both sides of the channel. By raising the adjustment rod 44 to the corresponding stop position 45, the height of the sleeve 42 can be adjusted and fixed.
[0064] In one embodiment, the stop position 45 is set as a limit rod, and the surface of the second fixed rod 41 is provided with a positioning block for cooperating with the limit rod. When the adjusting rod 44 has been raised to the corresponding height, the limit rod can be installed through the positioning block. The limit rod is used to prevent the adjusting rod 44 from falling under its own weight, thereby achieving height locking of the support surface 43.
[0065] In this embodiment, preferably, the second fixing rod 41 is cylindrical, and the multiple stop positions 45 are connected by a sliding channel 46, and the adjusting rod 44 can slide within the sliding channel 46.
[0066] The second fixed rod 41 is cylindrical, and the sleeve 42 is cylindrical. While the sleeve 42 moves up and down along the second fixed rod 41, it can also rotate relative to the second fixed rod 41.
[0067] The adjusting rod 44 is fixedly connected to the sleeve 42. When the adjusting rod 44 slides in the sliding channel 46, it can drive the sleeve 42 to move until the adjusting rod 44 engages with the stop position 45, and the relative position of the sleeve 42 and the second fixed rod 41 remains stable.
[0068] Preferably, the sliding channel 46 is positioned relatively low at the stop position 45, so that the adjusting rod 44 cannot disengage from the stop position 45 on its own after entering the stop position 45, thereby ensuring the reliable position of the sleeve 42.
[0069] In this embodiment, preferably, a marker is provided near the stop position 45.
[0070] Each stop 45 is marked with an identifier that corresponds to a different vehicle model for easy use.
[0071] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0072] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0073] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
