Description

Technical Field

[0001] The present invention relates to the technical field of forklifts, and particularly relates to an integrated positioning tooling for forklift truck frame assembly. Background Art

[0002] A forklift is a tool commonly used for handling freight in daily life. It consists of a frame, a cab, a mast, a fork, etc. Among them, various support components for supporting other components, such as a pedal mounting plate, a roof guard mounting plate, an instrument rack mounting plate, a shield mounting plate, etc., need to be fixedly welded on the frame, and the installation positions have relatively high requirements. For example, as a support component for pedal installation, the position dimension accuracy of the forklift pedal mounting plate will not only affect the installation clearance but also affect the driver's comfort; as a part for supporting and positioning the roof guard, the accuracy of the roof guard mounting plate will affect the installation accuracy of the roof guard and the cab; as a component for installing the instrument rack, the positioning accuracy of the instrument rack mounting plate will affect the installation accuracy of the instrument rack and the operating system; as a part for fixing the shield, the accuracy of the shield mounting plate will affect the installation clearance of the shield; as an important component in the forklift, the fender not only plays an important role in the structural strength of the frame but also serves as an important connecting part, and its accuracy will affect the positioning dimensions of other components.

[0003] In view of the positioning requirements and correlations of the above components, it is necessary to design a composite tooling to position the above components to meet the production requirements. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated positioning tooling for forklift truck frame assembly, which can realize the integrated positioning of components such as a pedal mounting plate, a roof guard mounting plate, an instrument rack mounting plate, a shield mounting plate, and a fender on the frame. It is simple to operate and has high efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] An integrated positioning tooling for forklift truck frame assembly includes two symmetrically and fixedly arranged fixed seats. A pull rod is erected between the two fixed seats, and a movable component is installed on the inner side wall of the fixed seat; the movable component includes a support rod connected to the fixed seat, a roof guard positioning plate and a connecting rod are respectively connected to the support rod, and a shield positioning block is connected to the connecting rod.

[0007] The movable components are symmetrically installed on the fixed seats in two, and are used for positioning the roof guard mounting plate, the shield mounting plate and the pedal mounting plate.

[0008] Further solution: The roof guard positioning plate and the connecting rod are relatively vertically installed on the support rod. A roof guard positioning member for positioning the roof guard mounting plate is installed on the roof guard positioning plate; Pedal positioning members for positioning the front and rear pedal mounting plates are respectively installed on the connecting rod; A shield plate positioning member for positioning the shield plate mounting plate is installed on the shield plate positioning block.

[0009] Even further solution: The roof guard positioning member, the pedal positioning member, and the shield plate positioning member are all positioning pin structures; One end of the connecting rod is connected with a connecting handle for connecting with the support rod.

[0010] The positioning pin structure is convenient to assemble and its height can be adjusted, which is convenient to make close contact with the roof guard mounting plate, the shield plate mounting plate, and the pedal mounting plate, improving the accuracy of the later assembly operation.

[0011] Further solution: An installation groove matching with the shield plate positioning block is opened on the top end surface in the middle of the connecting rod. Front pedal positioning blocks and rear pedal positioning blocks are respectively fixed on the bottom end surfaces of the connecting rod on both sides of the installation groove. Positioning holes are opened in the middle of the installation groove, the front pedal positioning block, and the rear pedal positioning block.

[0012] The front pedal positioning block and the rear pedal positioning block are mainly used to position the front and rear pedals, and then further positioning and installation are carried out through the positioning members.

[0013] Further solution: The movable component is connected with the fixed seat through a positioning pin, and the movable component can rotate around the positioning pin.

[0014] Further solution: In order to fix the movable component, the movable component is fixedly connected with the fixed seat through a clamp. That is, after the movable component is adjusted to a suitable position, it is fixed on the fixed seat through the clamp so as to position the roof guard mounting plate, the shield positioning plate, and the pedal mounting plate.

[0015] The clamp includes a mounting seat fixedly installed on the fixed seat. An activity clamp is connected to the mounting seat through a rotating shaft. A pressing column is fixedly provided on the activity clamp in the rotating direction of the activity clamp. When the movable component is connected through the positioning pin, it is exactly located below the pressing column. The activity clamp can rotate around the rotating shaft one. When the activity clamp rotates towards the movable component, the activity clamp drives the pressing column to move together and press against the movable component, thereby fixing the movable component and preventing it from shifting.

[0016] Further solution: The fixed seat includes a base fixedly installed on the workbench. A positioning side plate is fixed on the inner side wall of the base. A pull rod positioning seat and a mudguard positioning member are fixedly arranged in parallel on the top end of the base. The top end of the mudguard positioning member is connected with an adjustable-height positioning column; A pull rod positioning block is connected to the outside of the pull rod positioning seat.

[0017] The end of the pull rod is placed on the pull rod positioning seat, and its top is abutted against the pull rod positioning block, that is, the top of the pull rod is limited by the pull rod positioning block.

[0018] In a further solution, the pull rod positioning seat includes a mounting plate and a positioning vertical plate fixed to one end of the mounting plate. The side surface of the positioning vertical plate relative to the mounting plate is an arc structure. An arc-shaped convex block is fixedly provided at one end of the mounting plate where it is located between the arc-shaped convex block and the positioning vertical plate. A semi-circular arc-shaped groove is provided.

[0019] Preferably, mounting holes are provided on both the positioning vertical plate and the mounting plate, and the positioning column is a bolt threadedly connected to the mudguard positioning member.

[0020] In a further solution, the pull rod includes a pull rod body, and instrument rack positioning plates are respectively and vertically fixed to both ends of the pull rod body, and instrument rack positioning holes are provided on the instrument rack positioning plates.

[0021] During use, the pull rod is erected between two fixed seats, and its end is fitted and attached to the arc-shaped convex block on the pull rod positioning seat and the arc-shaped surface of the positioning vertical plate. The design of the arc-shaped convex block and the semi-circular arc-shaped groove can better position the pull rod; the top surface of the pull rod is fitted and attached to the pull rod positioning block, and the pull rod positioning block plays the role of both limiting and positioning at the same time. Finally, the pull rod is fixedly connected to the instrument rack mounting plate through the bolt passing through the instrument rack positioning hole, so as to play the role of controlling the welding deformation of the vehicle frame.

[0022] This tooling realizes the positioning of multiple support and installation components such as the pedal mounting plate, the roof guard mounting plate, the instrument rack mounting plate, and the shield mounting plate. It belongs to an integrated tooling, which can not only ensure the positioning accuracy of a single component, but also well ensure the dimensional correlation.

[0023] This tooling has a simple structure and consists of a movable component, a fixed seat and a pull rod. The movable component can be flipped on the fixed seat and fixed by a clamp when positioning is required. When demoulding is required, it can be flipped around the positioning pin. Therefore, this tooling has a simple structure, is convenient for assembly and positioning, and does not affect the demoulding operation.

[0024] In this tooling, the pull rod not only serves as a positioning part to position the instrument rack mounting plate, but also effectively controls the welding deformation during the welding of the vehicle frame. Brief Description of the Drawings

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] As Figures 1-7As shown in the figure, an integrated positioning tooling for forklift truck frame assembly includes two symmetrically and fixedly arranged fixing seats 1. A pull rod 3 is arranged between the two fixing seats 1. An active component 2 is installed on the inner side wall of the fixing seat 1. The active component 2 includes a support rod 21 connected to the fixing seat 1. A roof guard positioning plate 22 and a connecting rod 24 are respectively connected to the support rod 21. A shroud plate positioning block 26 is connected to the connecting rod 24.

[0043] The active component and the fixing seat are also symmetrically arranged. Two of them are symmetrically installed on the fixing seat and are used for positioning the roof guard mounting plate, the shroud plate mounting plate and the pedal mounting plate.

[0044] In a further solution, the roof guard positioning plate 22 and the connecting rod 24 are installed on the support rod 21 relatively vertically. A roof guard positioning member 23 for positioning the roof guard mounting plate is installed on the roof guard positioning plate 22. Pedal positioning members 25 for positioning the front and rear pedal mounting plates are respectively installed on the connecting rod 24. A shroud plate positioning member 27 for positioning the shroud plate mounting plate is installed on the shroud plate positioning block 26.

[0045] The roof guard positioning plate 22 and the connecting rod 24 are located on the adjacent sides of the support rod 21 and are both vertically connected, such as by welding or bolt connection.

[0046] In a further improved solution, the roof guard positioning member 23, the pedal positioning member 25 and the shroud plate positioning member 27 are all of positioning pin structures. One end of the connecting rod 24 is connected with a connecting handle 241 for connecting with the support rod 21.

[0047] The positioning pin structure is convenient to assemble. During use, it can be inserted into the corresponding positioning holes at any time. And different sizes of positioning pin structures can be replaced according to the changes in the sizes and models of the actual frame or roof guard mounting plate, etc., which is convenient to be in close contact with the roof guard mounting plate, the shroud plate mounting plate and the pedal mounting plate, and improves the accuracy of the later assembly operation.

[0048] In a further solution, an installation groove 245 matching with the shroud plate positioning block 26 is formed on the top end surface in the middle of the connecting rod 24. A front pedal positioning block 242 and a rear pedal positioning block 243 are respectively fixed on the bottom end surfaces of the connecting rod on both sides of the installation groove 245. Positioning holes 244 are formed in the middle of the installation groove 245, the front pedal positioning block 242 and the rear pedal positioning block 243 for installing the positioning pin structure.

[0049] The front pedal positioning block and the rear pedal positioning block are mainly used for positioning the front and rear pedals, and then further positioning and installation are carried out through the positioning members.

[0050] Further solution: The movable component 2 is connected to the fixed seat 1 through a positioning pin 4, and the movable component can be flipped around the positioning pin without causing occlusion or obstruction during operation.

[0051] Further solution: In order to fix the movable component, the movable component 2 is fixedly connected to the fixed seat 1 through a clamp 5. That is, after the movable component is adjusted to the appropriate position, it is fixed to the fixed seat through the clamp, so as to position the roof guard mounting plate, the shield positioning plate and the pedal mounting plate.

[0052] As Figure 7 shown, the clamp 5 includes a mounting seat 51 fixedly installed on the fixed seat 1. An active clamp 54 is connected to the mounting seat 51 through a rotating shaft 52. A pressure column 53 is fixedly provided on the active clamp 54 in the rotating direction of the active clamp 54. When the movable component is connected through the positioning pin, it is exactly located below the pressure column. The active clamp can rotate around the rotating shaft. When the active clamp rotates towards the movable component, the active clamp drives the pressure column to move together and press against the movable component, thereby fixing the movable component and preventing it from shifting. For convenient operation and wide adaptability, the pressure column 53 can be composed of a base fixed on the active clamp and a threaded column threadedly connected to the base. The height of the threaded column can be adjusted by rotation, so as to better press the movable component. A nut can also be used to lock the end of the threaded column to prevent thread slipping.

[0053] Further solution: The fixed seat 1 includes a base 11 fixedly installed on the workbench 6. A positioning side plate 16 is fixed on the inner side wall of the base 11. A pull rod positioning seat 12 and a mudguard positioning member 15 are fixedly provided in parallel at the top of the base 11. A height-adjustable positioning column 14 is connected to the top of the mudguard positioning member 15; a pull rod positioning block 13 is connected to the outside of the pull rod positioning seat 12.

[0054] The end of the pull rod is placed on the pull rod positioning seat and abuts against the top pull rod positioning block, that is, the top of the pull rod is limited by the pull rod positioning block.

[0055] Even further solution: The pull rod positioning seat 12 includes a mounting plate 125 and a positioning vertical plate 122 fixed to one end of the mounting plate. The side surface of the positioning vertical plate 122 relative to the mounting plate 125 is an arc structure. An arc-shaped convex block 121 is fixedly provided at one end of the mounting plate 125 where the positioning vertical plate 122 is located. A semi-circular groove 124 is provided between the arc-shaped convex block 121 and the positioning vertical plate 122.

[0056] The arc-shaped bump is for better fitting with the end of the pull rod. A semi-circular groove 124 is provided between the arc-shaped bump 121 and the positioning vertical plate 122 to create a force that causes the pull rod to tilt towards the positioning vertical plate 122 when placed, so that the pull rod can be placed on the pull rod positioning seat 12 and is not prone to sliding.

[0057] Preferably, mounting holes 123 are provided on both the positioning vertical plate 122 and the mounting plate 125. The pull rod positioning seat 12 is fixed to the fixed seat by a fixing bolt passing through the mounting hole on the mounting plate 125, and the pull rod positioning block 13 is connected and fixed to the positioning vertical plate 122 by a bolt passing through the mounting hole.

[0058] The positioning post 14 is a bolt threadedly connected to the fender positioning member 15. During use, the height of the bolt is adjusted according to the actual situation to facilitate positioning of the fender.

[0059] In a further solution, the pull rod 3 includes a pull rod body 31, and instrument rack positioning plates 33 are vertically fixed to both ends of the pull rod body 31, and instrument rack positioning holes 32 are provided on the instrument rack positioning plates 33.

[0060] During use, the pull rod is erected between two fixed seats, and its ends are fitted and matched with the arc-shaped surface of the arc-shaped bump and the positioning vertical plate on the pull rod positioning seat. The design of the arc-shaped bump and the semi-circular groove can better position the pull rod; the top surface of the pull rod is fitted and matched with the pull rod positioning block, and the pull rod positioning block plays a role of limiting and positioning at the same time. Finally, the pull rod is fixedly connected to the instrument rack mounting plate through the instrument rack positioning hole by a bolt, thereby playing a role in controlling the welding deformation of the vehicle frame.

[0061] The process of using this tooling is as follows:

[0062] 1. Fix two fixed seats 1 symmetrically on the workbench 6, as Figure 8 shown;

[0063] 2. Place the left and right fender mounting plates 7 on the vehicle frame 12 on the positioning posts 14 on the fixed seats 1 respectively;

[0064] 3. Place both ends of the pull rod 3 on the pull rod positioning seats 12 on the fixed seats 1, just against the arc-shaped bump 121 and the positioning vertical plate 122, and the ends are limited by the pull rod positioning block 13; then use a bolt to pass through the instrument rack positioning hole 32 on the instrument rack positioning plate 33 and fixedly connect it to the instrument rack mounting plate 11;

[0065] 4. Install the movable component 2. Connect the movable component 2 to the fixed seat 1 through the positioning pin 4. Adjust its position so that the roof guard positioning plate 22, front pedal positioning block 242, rear pedal positioning block 243, and shield plate positioning block 26 on the movable component 2 are respectively aligned with the roof guard mounting plate, plate mounting plate, and shield plate mounting plate. Then clamp and fix them with the clamp 5. The roof guard mounting plate 8, pedal mounting plate 10, and shield plate mounting plate 9 can be positioned through the roof guard positioning part 23, pedal positioning part 25, and shield plate positioning part 27 respectively, as Figures 9-10 shown;

[0066] 5. Weld the fender mounting plate 7, roof guard mounting plate 8, shield plate mounting plate 9, pedal mounting plate 10, and instrument rack mounting plate 11 to the vehicle frame 12. Then loosen the clamp 5, remove the movable component 2, and demold.

[0067] That is, this tooling realizes the positioning of multiple support and mounting components such as the pedal mounting plate, roof guard mounting plate, instrument rack mounting plate, and shield plate mounting plate, ensuring the welding accuracy. It belongs to an integrated tooling, which can not only ensure the positioning accuracy of a single component but also well ensure the dimensional correlation.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
