Technical Field
[0001] The utility model relates to the technical field of half - shaft processing fixtures, in particular to an efficient forklift half - shaft taper hole processing fixture. Background Art
[0002] A forklift is an industrial handling vehicle, referring to various wheeled handling vehicles for loading, unloading, stacking, and short - distance transportation operations of palletized goods. It is commonly used for transporting large objects in warehousing and is usually powered by a fuel engine or a battery.
[0003] Currently, in the process of using existing forklifts, a half - shaft is required to connect between the coupling and the power equipment. The half - shafts used are mostly semi - circular rods, which are used to clamp and fix the output part between the coupling and the power equipment. However, since one side of the half - shaft is semi - circular, it is very difficult to position the semi - circular surface during processing, resulting in easy deviation during processing and affecting the processing accuracy. Summary of the Utility Model
[0004] The utility model aims to solve the problems of the existing technology and provides an efficient forklift half - shaft taper hole processing fixture.
[0005] To solve the above - mentioned technical problems, the basic concept of the technical solution adopted by the utility model is as follows:
[0006] An efficient forklift half - shaft taper hole processing fixture includes a base. The interior of the base is hollow and the top is open. A clamping block is arranged near one side edge inside the base, and a movable plate is arranged near the other side edge inside the base. An arc - shaped positioning groove is formed on one side of the clamping block, and a half - shaft body is arranged inside the arc - shaped positioning groove. The arc surface of the half - shaft body fits with the arc surface of the arc - shaped positioning groove.
[0007] Optionally, a plurality of taper holes are equidistantly arranged on one side of the half - shaft body, and a plurality of conical drills are equidistantly arranged on one side of the movable plate.
[0008] Optionally, a second screw is arranged on one side of the base, and a first screw is arranged on the other side of the base. One end of the second screw is rotatably connected to the clamping block, and one end of the first screw is rotatably connected to the movable plate.
[0009] Optionally, discharge grooves are formed on the bottom surface of the interior of the base near both side edges, and one end of each of the two discharge grooves penetrates to the outside of the base.
[0010] Optionally, guide grooves are formed on both inner walls of the base, and sliding blocks are fixed on both outer surfaces of the clamping block and both outer surfaces of the movable plate, and the sliding blocks are slidably connected inside the guide grooves.
[0011] Optionally, a through hole penetrating to the bottom of the arc-shaped positioning groove is formed at the top of the clamping block near the front edge, and cushion grooves are formed on both sides of the through hole near the rear surface edge.
[0012] Optionally, a baffle is arranged inside the through hole, notches are formed on both sides of the rear side of the baffle near the edges, and rubber cushion strips are correspondingly arranged between the two notches and the opposite sides of the two cushion grooves.
[0013] After adopting the above technical solutions, the present utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the present utility model does not necessarily need to achieve all the advantages described below:
[0014] 1. In the present utility model, when using the device, the half shaft body is placed inside the arc-shaped positioning groove, and the arc surface on the half shaft body is opposite to the arc surface inside the arc-shaped positioning groove. Then, the baffle is inserted into the through hole, so that the outer surface of the baffle is attached to the flat surface of the half shaft body, thereby fixing the half shaft body inside the arc-shaped positioning groove to prevent shaking during subsequent drilling. At the same time, in order to prevent a gap between the contact surface of the baffle and the half shaft body, the rubber cushion strip is inserted between the opposite sides of the cushion groove and the notch, thereby playing a role in supporting the half shaft body.
[0015] 2. In the present utility model, after the half shaft body is fixed, by rotating the first screw rod to push the movable plate to move towards the clamping block, the conical drill bit on the movable plate can drill holes on the flat surface of the half shaft body. At the same time, the second screw rod can also be rotated to drive the clamping block to move, making it more convenient for people to adjust. When the movable plate and the clamping block move, through the mutual engagement of the guiding groove and the sliding block, the sliding of the movable plate and the clamping block is more stable.

[0025] The overall effect achieved by the entire Embodiment 1 is that when using this device, the half shaft body 7 is placed inside the arc-shaped positioning groove 15, and the arc surface on the half shaft body 7 is opposite to the arc surface inside the arc-shaped positioning groove 15. Then, the baffle 9 is inserted into the through hole 13, so that the outer surface of the baffle 9 is attached to the plane of the half shaft body 7, thereby fixing the half shaft body 7 inside the arc-shaped positioning groove 15 to prevent shaking during subsequent drilling. At the same time, in order to prevent there being a gap between the contact surfaces of the baffle 9 and the half shaft body 7, the rubber gasket strip 10 is inserted between the opposite sides of the pad groove 14 and the notch 11, thereby playing a supporting role for the half shaft body 7.

A plurality of tapered drills 12 are equidistantly arranged on one side of the movable plate 3. A second screw rod 5 is arranged on one side of the base 1, and a first screw rod 4 is arranged on the other side of the base 1. One end of the second screw rod 5 is rotatably connected to the clamping block 2, and one end of the first screw rod 4 is rotatably connected to the movable plate 3. Drainage grooves 6 are opened on the inner bottom surface of the base 1 near the edges on both sides. One end of each of the two drainage grooves 6 penetrates to the outside of the base 1. Guide grooves 16 are opened on the inner walls on both sides of the base 1. Sliders 17 that are slidably connected to the inside of the guide grooves 16 are fixed on the outer surfaces on both sides of the clamping block 2 and the outer surfaces on both sides of the movable plate 3.

Then insert the baffle 9 into the through hole 13 so that the outer surface of the baffle 9 fits the plane of the half shaft body 7, thereby fixing the half shaft body 7 inside the arc-shaped positioning groove 15 to prevent shaking during subsequent drilling. At the same time, in order to prevent there being a gap between the contact surface of the baffle 9 and the half shaft body 7, insert the rubber gasket strip 10 between the opposite sides of the pad groove 14 and the notch opening 11, thereby playing a supporting role for the half shaft body 7. After the half shaft body 7 is fixed, by rotating the first screw rod 4 to push the movable plate 3 to move towards the clamping block 3, the tapered drills 12 on the movable plate 3 can drill holes on the plane of the half shaft body 7. At the same time, the second screw rod 5 can also be rotated to drive the clamping block 2 to move, making it more convenient for people to adjust. When the movable plate 3 and the clamping block 2 move, through the mutual engagement of the guide groove 16 and the slider 17, the sliding of the movable plate 3 and the clamping block 2 is more stable.
