Description

Technical Field

[0001] This application relates to the field of forklift parts processing, and in particular to a forklift rear axle rocker arm processing technology and drilling equipment for the process. Background Technology

[0002] The rear axle refers to the rear drive shaft component that transmits power to a vehicle. It consists of two half-axles, allowing for differential movement between the half-axles. It also serves to support the wheels and connect the rear wheels.

[0003] The rear axle rocker arm is an important component of the rear axle. It is formed by welding a cut connecting tube, a cast plate, and the rear fork. After the rear axle rocker arm is welded, holes are drilled in the plate and the rear fork using drilling equipment.

[0004] Drilling directly into the rear fork and plate, which are both made of hard metal, can easily cause the drill bit to slip and become damaged. Summary of the Invention

[0005] To reduce the probability of damaging the drill bit during drilling, this application provides a machining process for a forklift rear axle rocker arm.

[0006] The forklift rear axle rocker arm processing technology provided in this application adopts the following technical solution: A forklift rear axle rocker arm manufacturing process includes the following steps: S1: Casting parts, the rear fork and plate are cast using molds. The molds for casting the rear fork and plate are core-pulling molds. The holes on the rear fork and plate are pre-cast using the core-pulling molds. The diameter of the pre-cast holes is smaller than the actual required diameter. S2: Surface polishing, which involves polishing the cast rear fork and plate, as well as the connecting pipes cut to the appropriate length. S3: Welding, using a welding gun to weld and fix the plate and rear fork onto the connecting pipe to form the rear axle rocker blank; S4: Hole enlargement, the rear axle rocker arm blank is installed in the drilling equipment to enlarge and drill the pre-cast hole; S5: Internal grinding, grinding the inner wall of the hole after enlargement to remove burrs generated during the enlargement process; S6: Spray painting, spray paint the rear axle rocker arm except for the holes; S7: Transfer and stacking. The rear axle rocker arm with the surface painted is transferred to the storage area and stacked.

[0007] By adopting the above technical solution, pre-cast holes at the required drilling locations can be pre-cast simultaneously when casting the rear fork and plate. This facilitates positioning during subsequent drilling, reduces the probability of drill bit slippage and damage during drilling, and saves materials. Since the casting surface is relatively rough, it needs to be polished after casting. The pre-cast hole diameter is smaller than the required hole diameter, which provides a margin for subsequent polishing.

[0008] Optionally, after flaring, the two ends of the hole can be chamfered.

[0009] By adopting the above technical solution, the chamfering can make the hole smoother, avoid damage to other parts when the end face is too sharp, and also guide the insertion of parts.

[0010] A drilling device for a forklift rear axle rocker arm includes a machine body, a worktable is provided inside the machine body, an mounting plate is provided on the worktable, a clamping mechanism for clamping the rear axle rocker arm is mounted on the mounting plate, and a drilling mechanism is provided above the mounting plate. The drilling mechanism includes a drill bit, which slides toward or away from the clamping mechanism.

[0011] By adopting the above technical solution, the probability of the rear axle rocker arm slipping during drilling is reduced by clamping the rocker arm and then drilling it, thereby improving the drilling accuracy.

[0012] Optionally, mounting platforms are provided at both ends of the workbench along its length, and rotating boxes are provided on both mounting platforms. Rotating disks are rotatably mounted on the rotating boxes, and the rotating disks at both ends rotate coaxially. The mounting plates are respectively mounted on the two rotating disks at both ends along their length. A power component is installed on one of the two rotating boxes, and the power component drives the rotating disk to rotate.

[0013] By adopting the above technical solution, the rotating disk drive mounting plate can drill holes at the other end of the rear axle rocker arm after drilling at one end, without the need for re-clamping, thus improving drilling efficiency.

[0014] Optionally, the rotating disk is rotatably mounted on the rotating box via a rotating shaft. A positioning mechanism is provided between the rotating shaft and the mounting platform. The positioning mechanism includes a positioning ring, a positioning groove, and a positioning element. The positioning ring is fitted onto the rotating shaft. Several positioning grooves are evenly distributed on the positioning ring. The positioning element is slidably mounted on the mounting platform. An elastic element is provided between the positioning element and the mounting platform. The elastic element drives the positioning element to abut against the positioning ring. When the positioning groove rotates to the positioning element area, the elastic element drives the positioning element to slide and insert into the positioning groove.

[0015] By adopting the above technical solution, the positioning mechanism can position the rotating disk during drilling, reducing the probability that the rotating disk will move during drilling and affect the drilling process.

[0016] Optionally, the positioning component includes a positioning platform and a positioning wheel. The positioning platform is slidably mounted on the mounting platform, and the positioning wheel is rotatably mounted on the positioning platform, with the positioning wheel abutting against the positioning ring.

[0017] By adopting the above technical solution and using positioning wheels for positioning, the positioning wheels can cooperate with the positioning ring to guide the rotation of the rotating disk under normal conditions, making the rotation of the rotating disk more stable.

[0018] Optionally, the drilling mechanism further includes a horizontal electric cylinder, a vertical electric cylinder, and a longitudinal electric cylinder. The horizontal electric cylinder is horizontally installed inside the machine body, the vertical electric cylinder is vertically installed on the horizontal electric cylinder, the longitudinal electric cylinder is horizontally installed on the vertical electric cylinder, and the drill bit is installed on the longitudinal electric cylinder. The horizontal electric cylinder drives the vertical electric cylinder to slide along the length direction of the machine body, the vertical electric cylinder drives the longitudinal electric cylinder to slide along the height direction of the machine body, and the longitudinal electric cylinder drives the drill bit to slide along the width direction of the machine body.

[0019] By adopting the above technical solution, the drill bit can be adjusted on three axes through the horizontal electric cylinder, the vertical electric cylinder and the longitudinal electric cylinder, thereby facilitating the adjustment of the drilling position and drilling depth.

[0020] Optionally, the clamping mechanism includes a support platform, a clamping platform, clamping bolts, and a pressure plate. The support platform is fixed at the middle position in the width direction of the mounting plate, and an inclined surface is opened on the top of the support platform. There are two clamping platforms, which are respectively set at both ends in the width direction of the mounting plate. The clamping platforms are set on one side of the inclined surface of the support platform, and clamping openings are opened on the inclined surface of the clamping platforms. The clamping bolts are threadedly connected to the clamping platforms, and one end of the clamping bolts extends into the clamping openings. The pressure plate is slidably set on the mounting plate, and the pressure plate slides towards or away from the support platform.

[0021] By adopting the above technical solution, the connecting pipe can be clamped and fixed by the support platform and the pressure plate. The rear forks at both ends of the connecting pipe can be fixed by the clamping platform and the clamping bolts, thereby realizing multi-point fixation of the rear axle rocker arm. This is more suitable for the rear axle rocker arm, making the fixation of the rear axle rocker arm more stable and reducing the probability of the rear axle rocker arm slipping during drilling.

[0022] In summary, this application includes at least one of the following beneficial technical effects: Pre-casting pre-formed holes at the locations where drilling is required during the casting of the rear fork and plate can facilitate positioning during subsequent drilling, reduce the probability of drill bit slippage and damage during drilling, and save materials. Since the casting surface is relatively rough, it needs to be polished after casting. The pre-cast hole diameter is smaller than the required hole diameter, which provides a margin for subsequent polishing. By clamping the rear axle rocker arm and drilling through it, the probability of the rear axle rocker arm slipping during drilling is reduced, thereby improving drilling accuracy. The rotating disk drive mounting plate can drill holes at the other end of the rear axle rocker arm after drilling at one end, without the need for re-clamping, thus improving drilling efficiency. The positioning mechanism can position the rotating disk during drilling, reducing the probability that the rotating disk will move during drilling and affect the drilling process. The drill bit can be adjusted on three axes by using a horizontal electric cylinder, a vertical electric cylinder, and a longitudinal electric cylinder, which makes it convenient to adjust the drilling position and drilling depth. The connecting pipe can be clamped and fixed by the support platform and pressure plate. The rear forks at both ends of the connecting pipe can be fixed by the clamping platform and clamping bolts, thereby realizing multi-point fixation of the rear axle rocker arm. This is more suitable for the rear axle rocker arm, making the fixation of the rear axle rocker arm more stable and reducing the probability of the rear axle rocker arm slipping during drilling.

The drilling mechanism 5 includes a drill bit 51, which slides toward or away from the clamping mechanism 4. By clamping the rear axle rocker arm, the system drills holes in the rear axle rocker arm, reducing the probability of the rear axle rocker arm slipping during drilling, thereby improving drilling accuracy.

[0032] Reference Figure 1 and Figure 2Mounting platforms 6 are slidably mounted at both ends of the worktable 2 along its length. The worktable 2 has a long groove with a cross-section of [insert cross-section here], within which adjusting bolts 24 are slidably mounted. A pressure plate 26 is positioned between the mounting platform 6 and the adjusting bolt 24. An adjusting nut 25 is connected to the adjusting bolt 24 by threads 19. The adjusting nut 25 fixes the pressure plate 44 to the worktable 2, and the pressure plate 26 secures the mounting platform 6 to the worktable 2. Loosening the adjusting nut 25 allows the mounting platform 6 to slide on the worktable 2; tightening the adjusting nut 25 fixes the mounting platform 6 to the worktable 2. Rotating boxes 7 are bolted to both ends of the mounting platform 6. Each of the two rotating boxes 7 has a rotating disk 8 on one side facing each other. The rotating disks 8 at both ends rotate coaxially. The two ends of the mounting plate 3 along its length are respectively mounted on the two rotating disks 8. One of the two rotating boxes 7 is equipped with a power component 9, which drives the rotating disk 8 to rotate. In this embodiment, the power component 9 is a geared motor. The mounting platform 6 is slidable to adjust the distance between the two mounting platforms 6, so as to be suitable for mounting plates 3 of different lengths. The synchronous sliding of the mounting platforms 6 can adjust the position of the mounting plate 3 on the worktable 2, thereby adjusting the drilling position. The rotating disk 8 drives the mounting disk to rotate, so that after drilling at one end of the rear axle rocker arm, drilling can be performed at the other end by rotating it without re-clamping, thus improving drilling efficiency.

A guide plate 13 is fixed on the mounting platform 6, which can guide the sliding of the positioning element 113. The elastic element 12 drives the positioning element 113 to abut against the positioning ring 111. When the positioning groove 112 rotates to the area of ​​the positioning element 113, that is, when the rear axle rocker arm is in the drilling state. The elastic element 12 drives the positioning element 113 to slide and insert into the positioning groove 112. The positioning element 113 includes a positioning platform 1131 and a positioning wheel 1132. The positioning platform 1131 is slidably mounted on the mounting platform 6 and is fixed to the elastic element 12. The positioning wheel 1132 is rotatably mounted on the positioning platform 1131 and abuts against the positioning ring 111. Guide arc surfaces are provided on both sides of the positioning groove 112. On the one hand, it can facilitate the positioning ring 111 to enter the positioning groove 112. On the other hand, it can make appropriate correction when there is a deviation in rotation. The positioning wheel 1132 enters the positioning groove 112 by rotating the rotating disk 8. The positioning mechanism 11 can position the rotating disk 8 during drilling, reducing the probability of the rotating disk 8 moving during drilling and affecting the drilling. The positioning wheel 1132 is used for positioning. Under normal conditions, the positioning wheel 1132 can cooperate with the positioning ring 111 to guide the rotation of the rotating disk 8, making the rotation of the rotating disk 8 more stable.

The drill bit 51 can be adjusted on the three axes through the transverse electric cylinder 52, the vertical electric cylinder 53, and the longitudinal electric cylinder 54, thereby facilitating the adjustment of the drilling position and drilling depth.

[0035] Reference Figure 2 and Figure 5The clamping mechanism 4 includes a support platform 41 fixed at the middle position in the width direction of the mounting plate 3, two clamping platforms 42 respectively disposed at both ends in the width direction of the mounting plate 3, clamping bolts 43 threaded 19 onto the clamping platforms 42, and a pressure plate 44 slidably disposed on the mounting plate 3. The top of the support platform 41 has an inclined surface 14, and the clamping platforms 42 are disposed on one side of the inclined surface 14 of the support platform 41. The clamping platforms 42 have clamping openings 15 facing the inclined surface 14, and the clamping platforms 42 of the two clamping mechanisms 4 are separated from each other by the clamping openings 15. The two sides are connected and fixed to each other. One end of the clamping bolt 43 extends into the clamping port 15, and the pressure plate 44 slides toward or away from the support platform 41. The support platform 41 is used to support the connecting shaft. The opening of the inclined surface 14 can guide the connecting shaft to slide, so that the rear forks at both ends of the connecting shaft slide into the clamping port 15. Then, the rear forks are fixed by the clamping bolt 43 against the rear forks, and the connecting shaft is fixed by the sliding pressure plate 44. Thus, the clamping mechanism 4 can be used for irregularly shaped forklift rear axle rockers, which is convenient for fixing the rear axle rocker when drilling.

[0036] Reference Figure 2 and Figure 5 A top plate 16 is fixed to the side of the support platform 41 away from the clamping platform 42. A top plate bolt 17 is connected to the top plate 16 by threads 19. The top plate 16, in conjunction with the top plate bolt 17, can reduce the probability of the rear axle rocker arm disengaging from the opening side of the clamping port 15, thereby improving the clamping stability. A guide rod 18 is vertically fixed to the mounting plate 3. The guide rod 18 passes through the pressure plate 44. A thread 19 is opened on the end of the guide rod 18 away from the mounting plate 3. A positioning nut 20 is connected to the thread 19 on the guide rod 18. The positioning nut 20 abuts against the side of the pressure plate 44 away from the mounting plate 3. The guide rod 18 is used to guide the pressure plate 44. The guide rod 18, in conjunction with the positioning nut 20, can reduce the probability of the pressure plate 44 slipping away from the rear axle rocker arm, thereby reducing the impact of the clamping mechanism. The probability of the rear axle rocker arm detaching; a connecting block 21 is fixed on the mounting plate 3, the connecting block 21 connects to two clamping platforms 42, and two positioning plates 22 are fixed on the connecting block 21.

The positioning bolts 23 on the two positioning plates 22 face opposite directions. The connecting block 21 connects the two clamping platforms 42 to improve the structural strength of the clamping platforms 42, and at the same time provides installation space for the positioning plates 22. The two positioning plates 22, together with the positioning bolts 23 facing opposite directions, can abut against the plate body through the positioning bolts 23, restricting the sliding of the rear axle rocker arm in the length direction of the connecting shaft, and further improving the stability of the rear axle rocker arm clamping. The implementation principle of this application embodiment is as follows: After adjusting the spacing of the mounting platform 6, the mounting plate 3 is installed on the two rotating disks 8. The connecting shaft of the rear axle rocker arm is placed on the support platform 41. Under the guidance of the inclined plane 14, the rear axle rocker arm slides towards the clamping platform 42, causing the rear fork to enter the clamping opening 15. Then, the positioning bolt 23 is rotated so that the two positioning bolts 23 respectively abut against the two plates of the rear axle rocker arm to restrict the sliding of the rear axle rocker arm in the length direction. Then, the top plate bolt 17 is rotated to abut against the end of the rear axle rocker arm away from the clamping opening 15, restricting the rear axle rocker arm from sliding away from the clamping opening 15. Then, the clamping bolt 43 is rotated, and the clamping bolt 43 abuts against the rear fork, completing the rear axle rocker arm... The mounting plate 3 is clamped and fixed, and the end of the rear axle rocker arm that needs to be drilled is rotated so that the drill bit 51 is facing the rocker arm. At this time, the positioning wheel 1132 abuts against the positioning groove 112 opposite to the drilling direction under the elastic force of the elastic member 12. The drilling mechanism 5 is used to drill and enlarge the rear axle rocker arm. After the drilling and enlargement of one end of the rear axle rocker arm is completed, the mounting plate 3 is rotated so that the rear axle rocker arm rotates 180 degrees and the positioning wheel 1132 abuts against the positioning groove 112 opposite to the drilling direction under the elastic force of the elastic member 12. The drilling mechanism 5 is used to drill and enlarge the other end of the rear axle rocker arm. After the drilling and enlargement of both ends of the rear axle rocker arm is completed, the rear axle rocker arm is disassembled, and the enlargement processing of the rear axle rocker arm is completed.
