Specific embodiments

[0014] The automotive tie rod ball joint processing device includes a machine base 1, a clamping drive assembly 5, a feeding assembly 2, a longitudinal sliding seat 4, a guide groove base 6, a cutting assembly 9, a bearing plate 7 and a receiving chute 8 (see the attached Figure 1 , 2 and 3 of the specification).

[0015] The feeding assembly 2 is fixedly installed on the machine base 1 (see the attached Figure 1 , 2 and 3 of the specification). The feeding assembly 2 includes an assembly bracket 15, a storage inclined plate 16, a front limiting cylinder 19, a rear limiting cylinder 20 and a limiting hook 18 (see the attached Figure 4 and 5 of the specification).

[0016] A material storage inclined plate 16 is fixedly installed on the machine base 1 through an assembly bracket 15; limiting vertical plates 17 are symmetrically arranged on the material storage inclined plate 16. During work, workpieces to be processed (automobile pull rod ball heads) can be arranged side by side on the material storage inclined plate 16. The limiting vertical plates 17 serve to limit the workpieces.

[0017] A front limiting cylinder 19 and a rear limiting cylinder 20 are installed at intervals on the assembly bracket 15 above the material storage inclined plate 16; limiting rods 21 are installed on both the front limiting cylinder 19 and the rear limiting cylinder 20 (see the attached Figure 4 and 5 of the specification).

[0018] The distance between the limiting rods 21 of the front limiting cylinder 19 and the rear limiting cylinder 20 is one workpiece interval.

[0019] Limiting hook claws 18 are symmetrically arranged at the lower end of the material storage inclined plate 16 (see the attached Figure 4 and 6 of the specification).

[0020] The purpose of setting up the feeding assembly 2 in this way is: during work, workpieces to be processed (automobile pull rod ball heads) can be arranged side by side on the material storage inclined plate 16, so that the workpieces will always have a tendency to roll downward under the action of their own gravity. In the initial state, the rear limiting cylinder 20 will contact the material storage inclined plate 16, so that the rear limiting cylinder 20 can limit all the workpieces on the material storage inclined plate 16 on one side of it. During work, the rear limiting cylinder 20 drives the limiting rod 21 to move upward, and then all the workpieces will roll one station under the action of gravity, and the workpiece at the tail end will abut against the limiting rod 21 of the front limiting cylinder 19. Subsequently, the rear limiting cylinder 20 drives the limiting rod 21 to act, so that it separates the subsequent workpieces; at this time, there is only a single workpiece between the front limiting cylinder 19 and the rear limiting cylinder 20, and then the front limiting cylinder 19 drives the limiting rod 21 to move upward, so that the workpiece between the front limiting cylinder 19 and the rear limiting cylinder 20 will roll between the limiting hook claws 18 under the action of gravity. In this way, by repeating the above actions of the front limiting cylinder 19 and the rear limiting cylinder 20 in a cycle, the purpose of sequentially releasing the workpieces between the limiting hook claws 18 can be achieved.

[0021] A longitudinal sliding seat 4 is installed below the feeding assembly 2 through a driving motor 3 and a lead screw mechanism (see the attached Figure 1 , 2 and 3 of the specification). When the driving motor 3 works, it can drive the longitudinal sliding seat 4 to slide back and forth along the longitudinal direction on the machine base 1 through the lead screw mechanism.

[0022] A guide groove seat 6 is fixedly installed on the longitudinal sliding seat 4; a guide groove opening 14 is arranged on the guide groove seat 6 (see the attached Figure 4 and 6A bearing plate 7 is fixedly mounted on one side of the guide groove seat 6; the bearing plate 7 is slidably connected to the lower surface of the limiting hook 18; and a material receiving slide plate 8 is fixedly mounted on the other side of the guide groove seat 6.

[0023] A guide sleeve 10 is fixedly mounted at one end of the guide groove seat 6 ; a push rod 11 is mounted inside the guide sleeve 10 ; a push cylinder 12 is mounted at the lower part of the guide sleeve 10 ; and the push cylinder 12 is connected to the push rod 11 through a connecting plate 13 .

[0024] The purpose of setting the guide groove seat 6, the carrying plate 7 and the receiving slide plate 8 in this way is that when the workpiece released by the loading assembly 2 falls between the limiting hook claws 18, it will be placed on the carrying plate 7. Then the longitudinal slide 4 will drive the guide groove seat 6 to move below the limiting hook claws 18, and at this time the workpiece will fall into the inside of the guide groove 14 of the guide groove seat 6 under the action of gravity; and then the longitudinal slide 4 drives the guide groove seat 6 to correspond to the clamping drive assembly 5, and the push rod 11 will push the workpiece into the inside of the clamping drive assembly 5 along the guide groove 14 under the drive of the push cylinder 12.

[0025] A cutting assembly 9 is mounted on the longitudinal slide 4 on one side of the material receiving slide 8 (see the attached manual). Figure 1 and 7 The cutting assembly 9 includes a drive cylinder 38, a longitudinal slide 39, a transverse slide 40, a cutting blade A41 and a cutting blade B42 (see the attached manual). Figure 7 ).

[0026] A longitudinal slide 39 is mounted on the longitudinal slide 4 through a drive cylinder 38; a transverse slide 40 is mounted on the longitudinal slide 39 through a drive cylinder 38; and a cutting knife A41 and a cutting knife B42 are alternately mounted on the transverse slide 40. When working, the cutting knife A41 will first complete the cutting of the end of the workpiece under the cooperation of the longitudinal slide 39 and the transverse slide 40; then the cutting knife B42 will complete the cutting of the spherical surface of the workpiece under the cooperation of the longitudinal slide 39 and the transverse slide 40.

[0027] A clamping drive assembly 5 is mounted on the base 1 at one end of the longitudinal slide 4 (see the appendix of the manual). Figure 2 and 3 The clamping drive assembly 5 includes a mounting seat 22, a rotating sleeve 23, a clamping sleeve 27, a power motor 24 and a puller 28 (see the attached manual). Figure 8 , 9 and 10).

[0028] A mounting seat 22 is fixedly mounted on the base 1 at one end of the longitudinal slide 4; a rotating sleeve 23 is mounted in the mounting seat 22 through a bearing; a power motor 24 is mounted on the mounting seat 22; the power motor 24 is connected to one end of the rotating sleeve 23 through a transmission wheel 25 and a transmission belt (see the attached manual Figure 2 and 3). During operation, the power motor 24 can drive the rotating sleeve 23 to rotate through the transmission wheel 25 and the transmission belt.

[0029] A clamping sleeve 27 is slidably installed in the rotating sleeve 23 through a guiding key 26 (see the attached drawings of the specification Figure 10 and 12 ). When the rotating sleeve 23 rotates, it can drive the clamping sleeve 27 to rotate synchronously through the guiding key 26.

[0030] One end of the clamping sleeve 27 has a conical structure 29; the outer surface of the conical structure 29 is in contact connection with the edge of the rotating sleeve 23; a plurality of expansion joints 30 are uniformly arranged at one end of the conical structure 29 (see the attached drawings of the specification Figure 12 ).

[0031] The purpose of setting the clamping sleeve 27 like this is that when the workpiece is inserted into the clamping sleeve 27, when the clamping sleeve 27 is forced to move backward as a whole, the rotating sleeve 23 will squeeze the conical structure 29 of the clamping sleeve 27 through the edge, so that it deforms under the cooperation of the expansion joints 30 and squeezes the workpiece, so as to achieve the purpose of clamping the workpiece.

[0032] One end of the clamping sleeve 27 is connected to the longitudinal sliding seat 4 through a puller 28 (see the attached drawings of the specification Figure 8 , 9 and 10).

[0033] The puller 28 includes a pulling cylinder 34, a pulling ring 33 and a mating sleeve ring 31 (see the attached drawings of the specification Figure 8 , 9 and 10); a mating sleeve ring 31 is fixedly installed on the outer surface of one end of the clamping sleeve 27; an avoidance ring groove 32 is arranged on the circumferential surface of the mating sleeve ring 31; a pulling ring 33 is arranged outside the mating sleeve ring 31; one side of the pulling ring 33 is hinged to the mounting seat 22 through an ear; a pulling cylinder 34 is installed on the machine base 1 on the other side of the pulling ring 33; the pulling cylinder 34 is hinged to the pulling ring 33 through an ear; two groups of pulling slide pins 35 are symmetrically arranged inside the pulling ring 33; the pulling slide pins 35 are inserted into the avoidance ring groove 32.

[0034] The purpose of setting the puller 28 like this is: first, when the rotating sleeve 23 drives the clamping sleeve 27 to rotate, the mating sleeve ring 31 of the clamping sleeve 27 can maintain a sliding connection with the pulling slide pins 35 of the pulling ring 33 through the avoidance ring groove 32, thus avoiding the problem that the puller 28 hinders the rotation of the clamping sleeve 27; second, when the pulling cylinder 34 pulls the pulling ring 33 to move backward, the pulling ring 33 can drive the clamping sleeve 27 to move backward together with the pulling slide pins 35 and the mating sleeve ring 31, so as to achieve the purpose of clamping the workpiece by the clamping sleeve 27.

[0035] A blanking rod 36 is installed on the mounting base 22 through a blanking cylinder 37; the blanking rod 36 corresponds to the center of the clamping sleeve 27 (see the attached Figure 8 and 10 ). During operation, the blanking rod 36 can be inserted into the inside of the clamping sleeve 27 under the cooperation of the blanking cylinder 37 to push the workpiece out of the inside of the clamping sleeve 27.

[0036] When the automobile tie rod ball head processing device is working, first, the front limit cylinder 19 and the rear limit cylinder 20 of the feeding assembly 2 cooperate with each other to make the workpiece roll onto the bearing plate 7 between the limit hook claws 18 under the action of gravity; then, the driving motor 3 and the lead screw mechanism drive the guide groove seat 6 to move below the limit hook claws 18. At this time, the workpiece will fall into the inside of the guide groove opening 14 of the guide groove seat 6 under the action of gravity. Then, the longitudinal slide 4 drives the guide groove seat 6 to correspond to the clamping drive assembly 5, and then the push rod 11 will push the workpiece along the guide groove opening 14 to the inside of the clamping sleeve 27 of the clamping drive assembly 5 under the drive of the push cylinder 12.

[0037] After one end of the workpiece is inserted into the inside of the clamping sleeve 27, the pulling cylinder 34 of the puller 28 pulls the pulling ring 33 backward. During this process, the pulling ring 33 drives the clamping sleeve 27 to move backward a certain distance together with the pulling slide pin 35 and the mating collar 31. During the backward movement of the clamping sleeve 27, the rotating sleeve 23 will press the conical structure 29 of the clamping sleeve 27 through the edge, so that it is stressed and deformed to clamp the workpiece under the cooperation of the expansion joint 30.

[0038] After the clamping sleeve 27 clamps the workpiece, the power motor 24 drives the rotating sleeve 23 to rotate through the transmission wheel 25 and the transmission belt; during the rotation of the rotating sleeve 23, the clamping sleeve 27 and the workpiece are driven to rotate synchronously through the guide key 26.

[0039] During the rotation of the workpiece, the longitudinal slide 4 drives the cutting assembly 9 to correspond to the end of the workpiece; then, the cutting tool A41 of the cutting assembly 9 first completes the cutting of the end of the rotating workpiece under the cooperation of the longitudinal moving slide 39 and the transverse moving slide 40; then, the cutting tool B42 will complete the cutting of the spherical surface of the workpiece under the cooperation of the longitudinal moving slide 39 and the transverse moving slide 40.

[0040] After the cutting assembly 9 finishes cutting, the longitudinal slide 4 drives the receiving chute 8 to move to correspond to the workpiece. Then, the power motor 24 and the rotating sleeve 23 stop operating; then, the pulling cylinder 34 of the puller 28 pulls the pulling ring 33 back to its original position. At this time, the clamping sleeve 27 will reset and loosen the workpiece under its own elastic force.

[0041] After the clamping sleeve 27 releases the workpiece, the blanking rod 36 can be inserted into the interior of the clamping sleeve 27 under the cooperation of the blanking cylinder 37, and the workpiece is pushed out from the interior of the clamping sleeve 27. After the workpiece slides out of the clamping sleeve 27, it will fall onto the receiving chute 8 and slide down under its guidance. So far, the processing device for the automotive tie rod ball head has completed all the processing work of the automotive tie rod ball head, and the processing device for the automotive tie rod ball head can enter the next working cycle.

[0042] The processing device for the automotive tie rod ball head has a compact structure and ingenious design, and can continuously and mechanizedly complete the processing of the automotive tie rod ball head, thus solving the problem of low working efficiency existing in the existing processing methods of the automotive tie rod ball head, and is particularly suitable for the processing needs of the automotive tie rod ball head.
