Abstract
Description
Technical Field
[0001] This utility model belongs to the field of forklift drive axle processing technology, and in particular relates to a forklift drive axle processing loading mold. Background Technology
[0002] The forklift drive axle is the drive axle component on a forklift, used to adjust the power torque, including directional and magnitude adjustments. Specifically, the main structure of the forklift drive axle includes the axle housing assembly, reducer, differential, and half-shafts. In the manufacturing process of forklift drive axles, the axle housing is primarily machined on a lathe before the reducer, differential, and other components are installed onto it.
[0003] Because the bridge housing itself has a certain weight and is a highly irregularly shaped workpiece, in actual processing, the heavy bridge housing can only be manually loaded onto the fixture and locked before processing. Obviously, this loading method is not only inefficient, but also laborious to transport the heavy, irregularly shaped bridge housing, and has a relatively low safety factor.
[0004] Specifically, due to the high degree of heterogeneity of the drive axle housing, it is difficult for operators to move the housing in a stable manner during the transportation process. If the heavy housing slips on the operator's hand, it is very easy to fall and cause a safety accident.
[0005] Therefore, in the production process, finding a labor-saving, safe, and efficient way to load the bridge housing onto the machine tool fixture is of profound significance for improving the efficiency and safety of bridge housing processing. Utility Model Content
[0006] Based on the above background, the purpose of this utility model is to provide a forklift drive axle machining and feeding mold.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A forklift drive axle machining loading mold, characterized in that it includes a mechanical gripper fixture;
[0009] The mechanical gripper includes a gripper base, on which a double-piston cylinder is mounted; the piston rods at both ends of the double-piston cylinder are respectively fixedly connected to annular claw sleeves.
[0010] The mechanical gripper also includes bottom support mechanisms on both sides;
[0011] The bottom support mechanism includes a plurality of bottom support rollers, and a drive shaft is fixedly connected between the bottom support rollers;
[0012] Both ends of the drive shaft are rotatably connected to end frames, and the end frames are fixedly connected to the bottom of the clamp seat.
[0013] The bottom support mechanism also includes a motor that drives the drive shaft to rotate;
[0014] During the material handling process of the drive axle housing, the annular claw sleeve limits and grips both ends of the drive axle housing, while the bottom support rollers support the bottom of the drive axle housing.
[0015] Preferably, the clamp seat includes U-shaped portions symmetrically arranged on the left and right sides, and U-shaped sliding portions are integrally formed between the two ends of the U-shaped portions.
[0016] Preferably, a sliding seat is slidably connected between the U-shaped sliding portions;
[0017] The top of the annular claw sleeve is fixedly installed at the bottom position of the sliding seat.
[0018] Preferably, the sliding seat includes a seat body, and a sliding plate is fixedly connected to the left and right side walls of the seat body, and the sliding plate is slidably connected to the U-shaped sliding plate;
[0019] The piston rods of the dual-piston cylinders are respectively fixedly connected to drive push-pull rods that are fixedly installed on the base.
[0020] Preferably, a plurality of cylinder mounting brackets are fixedly connected between the U-shaped portions, and the cylinder barrel of the dual-piston cylinder is fixedly mounted on the cylinder mounting brackets;
[0021] A flange mounting plate mounted on the robotic arm is fixedly connected between the top of the cylinder mounting brackets.
[0022] Preferably, the bottom support roller includes a support roller and a support roller arm for mounting the support roller;
[0023] The support roller arm is fixedly connected to the drive shaft.
[0024] Preferably, the support arm includes a U-shaped wheel arm portion;
[0025] A rotating shaft is rotatably connected to the support roller, and a through hole is provided on the arm of the U-shaped wheel;
[0026] The rotating shaft and the through hole are elastically slidably connected by a spring rod.
[0027] Preferably, the spring rod includes a slide rod that is slidably connected to the rotating shaft, and the slide rod is vertically fixedly connected to the through hole;
[0028] Springs are respectively fitted onto the upper and lower ends of the slide rod, and the two ends of the springs are respectively fixedly connected to the through hole and the rotating shaft.
[0029] Preferably, the U-shaped wheel arm is fixedly connected to a U-shaped arm rod.
[0030] The U-shaped arm is fixedly connected to the drive shaft.
[0031] This utility model has the following beneficial effects:
[0032] 1. During operation, when the dual-piston cylinders work synchronously, they pull the sliding seats on both sides closer together. During this process, the annular claw sleeves move closer together until they fit onto the shaft-shaped structures at both ends of the drive axle housing. This completes the clamping of the drive axle housing.
[0033] 2. During operation, when the motors on both sides work synchronously, the drive shaft rotates, causing all the support roller arms and support roller structures to flip until the support rollers contact the bottom edge of the drive axle housing. At this point, due to the pressure on the support rollers, the drive shaft slides down within the through hole via the spring rod (specifically, the drive shaft on the support roller slides relative to the sliding rod, and the spring deforms during the sliding process). This further increases the distance between the support rollers and the drive axle housing until the support roller arms flip from an inclined state to a vertical state, at which point the support rollers are completely in contact with the bottom of the drive axle housing. Conversely, after loading is complete, under the drive of the motor, the support roller arms carry the support rollers outward during the flipping process. The drive shaft on the support rollers also moves up and down via the spring rod, changing the distance between the support rollers and the drive axle housing, facilitating their flipping out from the bottom of the drive axle housing.
[0034] This method enables the stable and safe feeding of heavy and irregularly shaped bridge housings during the material handling process, supported by two rows of rollers and in conjunction with the clamping sleeve. Attached Figure Description

[0045] Example 1
[0046] like Figure 1-5 As shown, a forklift drive axle machining and loading mold includes a mechanical gripper fixture. In existing methods, the mechanical gripper fixture is mounted on a robotic arm, which grips the material, achieving labor-saving, high-efficiency, and improved safety of the loading axle housing.
[0047] Specifically, the mechanical gripper fixture includes a fixture base 1, which is made of stainless steel and has the following shape: the fixture base 1 includes symmetrically arranged U-shaped portions 11 on the left and right sides, and U-shaped sliding portions 12 are integrally formed between the two ends of each U-shaped portion 11. The structure of the fixture base 1 is similar to a frame structure.
[0048] Furthermore, a double-piston cylinder 23 is installed on the fixture seat 1; the piston rods at both ends of the double-piston cylinder 23 are respectively fixedly connected to annular claw sleeves 4.
[0049] Specifically, a sliding seat 21 is slidably connected between the U-shaped sliding parts 12; the sliding structure of the sliding seat 21 is as follows: the sliding seat 21 includes a seat body, and a sliding plate part 211 is fixedly connected to the left and right side walls of the seat body, and the sliding plate part 211 is slidably connected to the U-shaped sliding parts 12 (the sliding plate part 211 has a sliding opening, and the sliding opening is slidably connected to the U-shaped sliding parts 12).
[0050] Meanwhile, the top of the annular claw sleeve 4 is fixedly installed at the bottom position of the sliding seat 21 (specifically, at the bottom position of the seat body).
[0051] Meanwhile, drive push-pull rods 22, which are fixedly installed on the seat, are respectively fixedly connected to the piston rods of the dual-piston cylinder 23.
[0052] During operation, when the dual-piston cylinders 23 work synchronously, they pull the sliding seats 21 on both sides closer together. During this process, the annular claw sleeves 4 move closer together until they fit onto the shaft-shaped structures at both ends of the drive axle housing. At this point, the clamping of the drive axle housing is completed.
[0053] During this process, the sliding seat 21 is slidably connected to the rigid U-shaped sliding part 12 by the sliding plate part 211, thus having a high load capacity.
[0054] After the material is fed, the subsequent dual-piston cylinder 23 drives the annular claw sleeve 4 to disengage.
[0055] Example 2
[0056] like Figure 1-5 As shown, based on the structure of Embodiment 1, this embodiment further includes a bottom support mechanism 5 on both sides of the mechanical gripper. The bottom support mechanism 5 allows the annular claw sleeve 4 to be rotated and supported on the bottom sides of the housing after being fitted onto both ends of the drive axle housing, thereby further increasing the stability of the loading process after the robotic arm grasps the material.
[0057] Specifically, the bottom support mechanism 5 includes several bottom support rollers, and a drive shaft 51 is fixedly connected between the bottom support rollers; end frames 55 (with suitable bearings installed on the end frames 55 in the conventional way) are rotatably connected to both ends of the drive shaft 51, and the end frames 55 are fixedly connected to the bottom of the clamp seat 1; the bottom support mechanism 5 also includes a motor 56 that drives the drive shaft 51 to rotate (the output shaft of the motor 56 is mounted on the drive shaft 51 in a manner similar to a coupling). The motor 56 is fixedly mounted on the end frame 55 via a connecting plate mounted on the motor 56.
[0058] The aforementioned bottom support roller includes a support roller 54 and a support roller arm on which the support roller 54 is mounted. The support roller arm is fixedly connected to the drive shaft 51. The shape of the support roller arm is as follows:
[0059] The support roller arm includes a U-shaped wheel arm portion 53; in the conventional manner, a rotating shaft 541 is rotatably connected to the support roller 54, and a through hole is provided on the U-shaped wheel arm portion 53; the rotating shaft 541 and the through hole are elastically slidably connected by a spring rod.
[0060] The spring rod includes a slide rod that is slidably connected to the rotating shaft, and the slide rod is vertically fixedly connected to the through hole; springs 542 are respectively sleeved on the upper and lower ends of the slide rod, and the two ends of the springs 542 are respectively fixedly connected to the through hole and the rotating shaft 541.
[0061] Meanwhile, the U-shaped wheel arm 53 is fixedly connected to the U-shaped arm rod 52; the U-shaped arm rod 52 is fixedly connected to the drive shaft 51.
[0062] During operation, when the motors 56 on both sides work synchronously, the drive shaft 51 rotates and carries all the support roller arm-support roller 54 structures to flip until the support roller 54 touches the bottom edge of the drive axle housing. At this time, due to the pressure on the support roller 54, the drive shaft 541 slides down in the through hole through the spring rod (specifically, the drive shaft on the support roller 54 slides relative to the slide rod, and the spring 542 deforms during the sliding process).
[0063] At this point, the distance between the support roller 54 and the drive axle housing increases further until the support roller arm flips from an inclined state to a vertical state, at which point the support roller 54 is completely against the bottom of the drive axle housing. Conversely, after loading is completed, under the drive of the motor 56, the support roller arm carries the support roller 54 outward during the flipping process. The rotating shaft 541 on the support roller 54 also carries the support roller 54 up and down through the spring rod, changing the distance between it and the drive axle housing, making it easier to flip out from the bottom of the drive axle housing.
[0064] This method enables the stable and safe feeding of heavy and irregularly shaped bridge housings during the material handling process, supported by two rows of support rollers 54 and in conjunction with the clamping sleeve.
[0065] After the material is loaded, when it is necessary to remove the bridge housing, the support roller 54 continues to slightly rotate and lift the housing under the drive of the motor 56. At this time, the friction between the annular claw sleeve 4 and the housing is reduced. According to the above embodiment, the annular claw sleeve 4 is removed under the drive of the double piston cylinder 23 and the entire workpiece is placed on the fixture of the lathe. Subsequently, the support roller 54 rotates outward under the drive of the motor 56 until it is separated from the workpiece in the housing.
[0066] Example 3
[0067] like Figure 1-5As shown, in this embodiment, based on the structure of Embodiment 1, several cylinder mounting brackets 24 are fixedly connected between the aforementioned U-shaped portions in a conventional manner. The cylinder barrel of the dual-piston cylinder 23 is fixedly mounted on the cylinder mounting bracket 24. Simultaneously, flange mounting plates 3 mounted on the robotic arm are fixedly connected between the tops of the cylinder mounting brackets 24 (specifically, several T-shaped seats 31 are welded to the top of the cylinder mounting brackets 24, and the flange mounting plates 3 are fixedly mounted on the T-shaped seats 31). The flange mounting plates 3 are mounted onto the flange connecting plate on the robotic arm in a conventional manner.
[0068] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
