Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of forklift assembly tooling, and particularly relates to a forklift fork frame assembly die convenient for demolding. BACKGROUND

[0002] The forklift fork frame is a core load-bearing component of the forklift, and is usually composed of two parallelly arranged cross beams, and longitudinal beams and connecting plates fixed between the two cross beams, the connecting plates being used for connecting the portal. The traditional forklift fork frame assembly tooling is provided with clamps or rigid positioning structures on the base thereof, so as to position limit part of the structure of the forklift fork frame. During the assembly process, the installation positions and angles of the various structures of the forklift fork frame need to be repeatedly measured and determined. Such tooling structure is simple and can meet the basic assembly requirements. However, the traditional forklift fork frame assembly tooling still needs to be improved.

[0003] On the one hand, the positioning structure of the traditional tooling is single, and can only partially constrain the structure in one direction, resulting in insufficient assembly accuracy. Moreover, the demolding operation of the forklift fork frame of the traditional assembly tooling is relatively complex. When the forklift fork frame is demolded, the positioning structure is likely to interfere, which is not conducive to lifting the forklift fork frame. Usually, part of the positioning structure needs to be removed to complete the demolding, thereby affecting the production efficiency. On the other hand, the positioning structure of the traditional tooling is difficult to adapt to forklift fork frames of different specifications. The positioning of forklift fork frames of different specifications needs to be realized by replacing the positioning structure mounting points, which is time-consuming and labor-consuming and difficult to guarantee the repeated positioning accuracy. The above problems result in poor flexibility and low adaptability of the traditional tooling, which is difficult to meet the efficient assembly requirements of forklift fork frames of different specifications in modern forklift production. SUMMARY

[0004] The utility model discloses a forklift fork frame assembly die convenient for demolding.

[0005] The utility model discloses a forklift fork frame assembly die convenient for demolding.

[0006] A forklift fork frame assembly die convenient for demolding, the forklift fork frame comprising two cross beams, and two longitudinal beams and two connecting plates arranged between the two cross beams, the assembly die comprising a base, and clamps being arranged on the two sides of the base in the transverse direction, a transverse positioning member being arranged between the two clamps, a plurality of pairs of longitudinal positioning members being arranged on the base in the transverse direction in sequence, a clamping opening being arranged on the upper part of the clamp to clamp the cross beam, the transverse positioning member being used for positioning the connecting plate from the side, and the longitudinal positioning member being used for positioning the longitudinal beam and the connecting plate from the side.

[0007] As a further optimization scheme of the utility model, the transverse positioning member is composed of a mounting frame one, a mounting plate hinged to the top of the mounting frame one, and a positioning rod arranged at one end of the mounting plate.

[0008] As a further optimization of this utility model, the lateral positioning component consists of a second mounting frame, two positioning blocks symmetrically arranged on both sides of the second mounting frame, and a connecting arm arranged between the second mounting frame and the positioning blocks.

[0009] As a further optimization of this utility model, the longitudinal positioning component consists of a bracket and a cam hinged to the top of the bracket.

[0010] As a further optimization of this utility model, the bracket is provided with two cams, and the lengths of the long sides of the two cams are different.

[0011] As a further optimization of this utility model, the longitudinal positioning component consists of a second bracket, a sliding rod slidably disposed on one side of the second bracket, and a position adjustment component for sliding the sliding rod.

[0012] As a further optimization of this utility model, the position adjustment component includes a handle hinged to the other side of the bracket, and a connecting rod hinged between the handle and the slide bar.

[0013] As a further optimization of this utility model, the longitudinal positioning members are provided in four pairs, of which two pairs of longitudinal positioning members are used to position the crossbeam and the other two pairs of longitudinal positioning members are used to position the connecting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1) The clamp of this utility model has an opening at the top for clamping the crossbeam. The transverse positioning component positions the connecting plate from the side, and the longitudinal positioning component positions the longitudinal beam and the connecting plate from the side. The mold provides comprehensive positioning of the fork carriage, improves positioning accuracy, and the above positioning structure does not interfere with the lifting of the fork carriage.

[0016] 2) This utility model can adapt to the positioning and assembly of fork carriages of different sizes. When positioning fork carriages of different sizes, it is not necessary to change the installation points of the lateral positioning parts and the longitudinal positioning parts. It is only necessary to adjust the working state of the lateral positioning parts and the longitudinal positioning parts in place, thereby improving the adaptability to different fork carriages, further improving the production efficiency of fork carriages, and avoiding the decrease in repetitive positioning accuracy caused by repeated disassembly and assembly of the positioning structure.

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Figure 1 The following embodiment illustrates one type of fork carriage to which the fork carriage is applicable. The fork carriage includes two symmetrical crossbeams F1, two longitudinal beams F2 fixedly disposed between the two crossbeams F1, and two connecting plates F3. The two longitudinal beams F2 are located at opposite ends of the crossbeams F1, and the two connecting plates F3 are both located between the two longitudinal beams F2. The forks are mounted on the crossbeams F1, as shown below. Figure 1As shown, connecting plate F3 is used to weld six roller shafts. Six rollers are mounted on these six roller shafts, and these rollers can move up and down within the gantry channel steel guide rails, thereby driving the crossbeam F1 and the forks to move up and down. Furthermore, the number of roller shafts welded to connecting plate F6 is not limited to six. It should be noted that... Figure 1 Only one type of fork carriage is shown in the figure. The following embodiments can also be applied to fork carriages with a shorter distance between the two crossbeams F1.

[0029] Example 1

[0030] like Figure 2 As shown, this embodiment relates to a forklift fork carriage assembly mold that facilitates demolding. The assembly mold includes a base 1, with clamps 2 detachably fixed on both sides of the base 1 in the lateral direction. A pair of lateral positioning members 3 are provided between the two clamps 2, and the lateral positioning members 3 are fixedly installed on the base 1. Multiple pairs of longitudinal positioning members 4 are sequentially fixed on the base 1 in the lateral direction, with two longitudinal positioning members 4 in each pair located on both sides of the longitudinal direction of the base 1. It should be noted that in this embodiment and the following embodiments, lateral direction refers to the length direction of the crossbeam F1 when assembling the fork carriage, and longitudinal direction refers to the length direction of the longitudinal beam F2 when assembling the fork carriage. The clamps 2 have clamping openings at the top for clamping the crossbeam F1. The lateral positioning members 3 are used to position the connecting plate F3 from the lateral side of the base 1, and the longitudinal positioning members 4 are used to position the longitudinal beam F2 and the connecting plate F3 from the longitudinal side of the base 1. There are four pairs of longitudinal positioning members 4, two pairs of which are used to position the crossbeam F1, and the other two pairs of longitudinal positioning members 4 are used to position the connecting plate F3.

[0031] When assembling the fork carriage, place the longitudinal beam F2 in the clamping opening of the clamp 2, and place the crossbeam F1 between the pairs of longitudinal positioning pieces 4, ensuring that both ends of the crossbeam F1 abut against the two longitudinal beams F2 respectively. Position one crossbeam F1 against the two longitudinal positioning pieces 4 on one side of the base 1, and position the other crossbeam F1 against the two longitudinal positioning pieces 4 on the other side of the base 1, thus completing the positioning of the crossbeam F1. Clamp and position the longitudinal beams F2 using the clamp 2. After fixing the two crossbeams F1 and the two longitudinal beams F2 together, position and assemble the connecting plate F3.

[0032] When assembling the connecting plate F3, place the two connecting plates F3 on the two crossbeams F1, and then attach the two connecting plates F3 to the two transverse positioning pieces 3 respectively. Next, adjust the longitudinal positioning pieces 4 to clamp the connecting plates F3 between the pairs of longitudinal positioning pieces 4, completing the positioning of the connecting plates F3. Then, weld the connecting plates F3 onto the crossbeams F1, completing the assembly of the connecting plates F3. At this point, the fork carriage assembly is complete.

[0033] Next, this embodiment will use Figure 1 Taking this large fork carriage as an example, the assembly process will be described in detail.Figure 2 and Figure 3 As shown, the clamp 2 in this embodiment includes a U-shaped frame 21 with a groove, a pressure rod 22 threadedly connected to one side of the U-shaped frame 21, and a pressure block 23 disposed at one end of the pressure rod 22. The pressure block 23 is rotatably disposed at the end of the pressure rod 22, and the bottom of the pressure block 23 is slidably connected to the U-shaped frame 21. The clamping opening of the clamp 2 is formed in the groove of the U-shaped frame 21. The base 1 is provided with a sliding groove corresponding to the U-shaped frame 21, and the U-shaped frame 21 is fixed to the base 1 by threaded fasteners.

[0034] When clamping and positioning the longitudinal beam F2, first slide the U-shaped frame 21 to the assembly position of the longitudinal beam F2, and fix the U-shaped frame 21 to the base 1 with threaded fasteners. Place the longitudinal beam F2 in the groove of the U-shaped frame 21, screw the pressure rod 22 into the groove, and slide the pressure block 23 toward the side of the U-shaped frame 21 away from the pressure rod 22, so that the longitudinal beam F2 is clamped between the pressure block 23 and the side wall of the groove of the U-shaped frame 21 away from the pressure rod 22, thus completing the fixation of the longitudinal beam F2.

[0035] like Figure 4 As shown, the longitudinal positioning component 4 in this embodiment consists of a bracket 41 and a cam 42 hinged to the top of the bracket 41. The bracket 41 has two cams 42, and the long side lengths of the two cams 42 are different. The longitudinal positioning component 4 corresponding to the crossbeam F1 is directly fixedly installed on the base 1, and the longitudinal positioning component 4 corresponding to the connecting plate F3 is fixedly installed on the base 1 through a mounting platform.

[0036] like Figure 5 As shown, the lateral positioning component 3 in this embodiment consists of a mounting bracket 31, two mounting plates 32 hinged to the top of the mounting bracket 31, and two positioning rods 33 located at one end of the mounting plates 32. The mounting bracket 31 is fixedly mounted on the base 1, and the positioning rods 33 are threadedly connected to the side of the mounting plates 32 away from the mounting bracket 31. A stop block corresponding to each mounting plate 32 is fixedly provided on one side of the mounting bracket 31. When the mounting plate 32 is rotated to the angle of overlap with the stop block, the positioning rods 33 are in a horizontal state.

[0037] During the assembly of the crossbeam F1, the crossbeam F1 is positioned between the corresponding pairs of longitudinal positioning pieces 4. The cam 42 with the shorter long side is rotated towards the crossbeam F1. After rotation, the cam 42 rests on the bracket 41, which supports the cam 42, keeping its long side horizontal. Each crossbeam F1 has two corresponding cams 42 for positioning. The sidewall of the crossbeam F1 is pressed against the end of the cam 42, completing the positioning of the crossbeam F1. Then, the crossbeam F1 is fixedly connected to the longitudinal beam F2.

[0038] When assembling the connecting plate F3, adjust the positioning rod 33 so that it extends outward from the mounting plate 32 by a suitable length, and rotate the mounting plate 32 to a horizontal position. Then, align the connecting plate F3 with the ends of the four positioning rods 33 of the corresponding transverse positioning member 3. Next, rotate the cams 42 with shorter long sides of the two longitudinal positioning members 4 corresponding to the connecting plate F3 so that the long sides of the two cams 42 are horizontal, and clamp the connecting plate F3 between the two cams 42, completing the positioning of the connecting plate F3. Then, weld the connecting plate F3 to the crossbeam F1 to complete the assembly of the connecting plate F3. At this point, the fork carriage is assembled. When lifting the fork carriage, there is no obstruction directly above the fork carriage, and the positioning structure does not need to be removed, improving the forklift assembly production efficiency.

[0039] For smaller fork carriages, the spacing between the two longitudinal beams F2, the two crossbeams F1, and the two connecting plates F3 are reduced. By removing the threaded fasteners, moving the two U-shaped frames 21 towards each other, and then fixing the U-shaped frames 21 with the threaded fasteners again, the positioning and assembly requirements of the longitudinal beams F2 of the fork carriage can be met. Orienting the longer cam 42 toward the corresponding crossbeam F1 can accommodate the positioning and assembly requirements of the crossbeam F1 of the fork carriage. Orienting the longer cam 42 toward the corresponding connecting plate F3 and adjusting the length of the positioning rod 33 extending from the mounting plate 32 can accommodate the positioning and assembly requirements of the connecting plate F3 of the fork carriage.

[0040] Example 2

[0041] like Figure 6 As shown, this embodiment relates to another forklift fork carriage assembly mold that facilitates demolding. The difference between this assembly mold and the previous embodiment lies in the different structures of the clamp 2 and the transverse positioning member 3. The two pairs of longitudinal positioning members 4 corresponding to the crossbeam F1 are the same as in the previous embodiment. The two pairs of longitudinal positioning members 4 corresponding to the connecting plate F3 differ from the previous embodiment; these longitudinal positioning members 4 are rotary-sliding positioning members.

[0042] Specifically, such as Figures 6-7 As shown, the aforementioned rotary-sliding positioning component comprises a second bracket 43, a slide rod 44 slidably disposed on one side of the second bracket 43, and a position adjustment component for sliding the slide rod 44. The position adjustment component includes a handle 45 hinged to the other side of the second bracket 43, and a connecting rod 46 hinged between the handle 45 and the slide rod 44. The second bracket 43 is fixedly mounted on the base 1 via a mounting platform.

[0043] Please see Figure 8In this embodiment, the lateral positioning component 3 consists of a second mounting bracket 34, two positioning blocks 35 symmetrically arranged on both sides of the second mounting bracket 34, and a connecting arm 36 located between the second mounting bracket 34 and the positioning blocks 35. The connecting arm 36 of the lateral positioning component 3 is fixed to the second mounting bracket 34 and the positioning blocks 35 by threaded fasteners. There are two lateral positioning components 3, which are located on both sides of the longitudinal direction in the middle of the base 1. When assembling the connecting plate F3, both lateral positioning components 3 are positioned between the two connecting plates F3.

[0044] When assembling the connecting plate F3, place the two connecting plates F3 on both sides of the transverse positioning member 3 in this embodiment, and abut the same sidewall of the connecting plate F3 against the positioning blocks 35 of the two transverse positioning members 3 to complete the transverse positioning of the connecting plate F3. Rotate the handle 45, and the handle 45 will push the sliding rod 44 against the connecting plate F3 through the connecting rod 46. Under the action of the weight of the handle 45, the sliding rods 44 of the pair of rotary-sliding positioning members will be in close contact with the connecting plate F3 to complete the longitudinal positioning of the connecting plate F3. The connecting plate F3 can then be welded to the crossbeam F1.

[0045] The clamp 2 in this embodiment includes an L-shaped frame 24 and a positioning component 25 disposed on one side of the L-shaped frame 24. The clamping opening of the clamp 2 is located between the positioning component 25 and the L-shaped frame 24. Both the L-shaped frame 24 and the positioning component 25 are fixed to the base 1 by threaded fasteners. The structure of the positioning component 25 is the same as that of the rotary-sliding positioning component described above. When clamping the longitudinal beam F2, rotating the handle of the positioning component 25 fixes the longitudinal beam F2 between the slide bar of the clamp 2 and the L-shaped frame 24.

[0046] For smaller fork carriages, adjusting the installation positions of the L-shaped bracket 24 and the positioning assembly 25 can accommodate the positioning and assembly requirements of the longitudinal beam F2 of the fork carriage. For the longitudinal positioning member 4, which is the same as in the previous embodiment, aligning the cam 42 with the longer side towards the corresponding crossbeam F1 can accommodate the positioning and assembly requirements of the crossbeam F1 of the fork carriage. In this embodiment, the connecting arm 36 of the transverse positioning member 3 has two screw holes on the side near the mounting bracket 2 34. By changing the screw holes used to fix the connecting arm 36, the positioning block 35 can be moved closer to the mounting bracket 2 34, shortening the distance between the two positioning blocks 35 on the same transverse positioning member 3. Then, by adjusting the rotation angle of the handle 45 of the rotary-sliding positioning member, the positioning and assembly requirements of the connecting plate F3 of the fork carriage can be accommodated.

[0047] Example 3

[0048] like Figure 9As shown, this embodiment relates to another forklift fork carriage assembly mold that facilitates demolding. The difference between this embodiment and the previous two embodiments is that this embodiment incorporates both the lateral positioning element 3 from Embodiment 1 and the lateral positioning element 3 from Embodiment 2. Furthermore, the four pairs of longitudinal positioning elements 4 in this embodiment are all rotary-sliding positioning elements from the previous embodiment. The lateral positioning element 3 in this embodiment is the same as that in Embodiment 2. During the positioning of the crossbeam F1, rotating the handle 45 positions the crossbeam F1. The fixture 2 in this embodiment is the same as in the previous embodiment and will not be described in detail.

[0049] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
