Description

Technical Field

[0001] The invention belongs to the field of mechanical processing and manufacturing equipment, and in particular relates to a composite turning and milling machine tool for automobile tie rods. Background Art

[0002] The lateral stabilizer bar of a heavy-duty truck is installed on the front and rear axles of the vehicle. It is also called an anti-roll bar or a tie rod. It is one of the key transmission accessories of a car. Its function is to prevent the car body from excessive lateral tilt when turning. The purpose is to prevent the car from tipping over and improve the smoothness of driving. The tie rod is usually set at the front and rear end of the car, and the two ends of the rod are respectively fixed to the left and right suspensions. When the car body only moves vertically, the deformation of the suspension on both sides is the same, and the lateral stabilizer bar does not work. When the car body rolls, the suspension on both sides jumps inconsistently, the tie rod twists, and the elastic force of the rod body becomes a resistance to continued roll, playing a role in lateral stability.

[0003] A machine tool is required for processing the tie rod. When processing the tie rod on the existing machine tool, the staff is usually required to place the tie rod on the machine tool and clamp it through the components on the machine tool, and then process the tie rod. After processing, the staff will remove the tie rod from the machine tool and continue to place the unprocessed tie rod. This is time-consuming and labor-intensive. In addition, during the processing, two large-scale equipment are generally required to complete the processing of the tie rod. Not only is the processing efficiency low, but it is also necessary to purchase multiple equipment, which increases the processing cost. Therefore, a machine tool is needed that can not only process the tie rod in multiple ways at the same time, but also can automatically load and unload materials. The present invention solves the above technical problems. Summary of the Invention

[0010] The chuck assembly 1 and the chuck assembly 2 together constitute a chuck, the bevel gear assembly 1 and the bevel gear assembly 2 together constitute a bevel gear 1, and the bevel gear 1 is connected to the driving mechanism.

[0011] Furthermore, the driving mechanism includes a bevel gear 2 meshing with the bevel gear 1, a gear box connected to the bevel gear 2 through an output shaft, and a spindle motor connected to the input end of the gear box. An open groove is provided on the side of the lower limit block, and the output shaft of the gear box is connected to the open groove.

[0012] Furthermore, the connecting mechanism includes a connecting arm 1 whose one end is fixed to the side of the lower limit block, a connecting column provided at the other end of the connecting arm 1, a connecting arm 2 whose one end is connected to the connecting column, and the other end of the connecting arm 2 is hinged to the feeding mechanism;

[0013] A sliding groove is provided at one end of the second connecting arm, and the connecting post is slidably and rotatably connected in the sliding groove.

[0014] Furthermore, the feeding mechanism includes a base frame, a storage box connected above the base frame and used to store the transverse tie rod, a feed port is vertically opened at the top of the storage box, a discharge port is opened on the side of the storage box, the feed port and the discharge port are connected by an L-shaped channel, a baffle plate is hinged on the outer side of the discharge port, and the end of the second connecting arm is hinged on the baffle plate.

[0015] Furthermore, a transverse rotating shaft is rotatably provided on the saddle, the side of the rotating shaft is connected to the bottom of the connecting block, a cylinder 1 is provided in the connecting block, the cylinder 1 is connected to the bottom of the lower limit block, and the end of the rotating shaft is connected to the forward and reverse motor.

[0016] Furthermore, the saddle is connected to the bottom end of the bracket, the bracket is in an inverted L-shape, and the other end of the bracket is vertically connected to cylinder 2, and the output end of cylinder 2 is connected to the upper limit block.

[0017] Furthermore, a through slot is transversely opened on the baffle plate, a rotating shaft is slidably connected in the through slot, the rotating shaft is rotatably connected in the through slot, and the side of the rotating shaft is connected to the end of the second connecting arm.

[0018] The technical effects of the present invention are as follows:

[0019] (1) The clamping mechanism in this solution achieves the following technical effects:

[0020] First, through the cooperation with the forward and reverse motors, the connecting mechanism, and the feeding mechanism, after the lower limit block driven by the forward and reverse motors rotates, the connecting arm 2 will rotate under the drive of the connecting arm 1, thereby driving the baffle plate of the feeding mechanism to rotate and open, so that the cross-bar in the feeding mechanism rolls out and rolls into the lower limit block through the connecting mechanism to complete the loading;

[0021] Second, after the loading is completed, the forward and reverse motors rotate in the opposite direction, driving the lower limit block to reset, and then driving the baffle plate to reset through the connecting mechanism to prevent other tie rods from rolling out, thus realizing the limit of the tie rods in the storage box;

[0022] Third, after the upper limit block and the lower limit block are combined, the driving mechanism is used to drive the internal tie rod to rotate, so that the upper limit block and the lower limit block play a role in limiting the tie rod, so that the position of the tie rod remains unchanged, and the separation of the chuck assembly 1 and the chuck assembly 2, and the bevel gear assembly 1 and the bevel gear assembly 2 is effectively prevented;

[0023] Fourth, after the processing is completed, the upper limit block is separated from the lower limit block, and the lower limit block can cooperate with the cylinder 1 to extend the output end of one cylinder 1 and keep the other cylinder 1 unchanged, so that the heights of the two lower limit blocks are different, causing the cross rod itself to tilt, making it easier to slide off the lower limit block, thus completing the blanking work;

[0024] (2) This solution uses a processing mechanism to process the tie rod in the x-axis, y-axis, and z-axis directions respectively, and the specific processing position can be adjusted. In addition, two processing mechanisms are provided on the slide rail, so that this device can process the tie rod in different ways at the same time, thereby improving the processing efficiency. In addition, there is no need to purchase multiple devices to process the tie rod, thus saving procurement costs.

[0025] (3) Since the end of the second connecting arm is connected to the side of the rotating shaft, and the rotating shaft is slidably connected in the through-groove, when the saddle moves, it will drive the rotating shaft to move in the through-groove through the lower limit block and the connecting mechanism, so that the loading work can be carried out when the lower limit block is in different positions.

[0050] Furthermore, a through slot 83 is transversely opened on the baffle plate 84 , and a rotating shaft 75 is slidably connected in the through slot 83 . The rotating shaft 75 is rotatably connected in the through slot 83 , and the side of the rotating shaft 75 is connected to the end of the second connecting arm 74 .

[0051] The working process of the present invention is as follows:

[0052] First, adjust the positions of the two saddles 4 respectively. During the movement of the saddle 4, the lower limit block 23 and the connecting mechanism 7 will drive the rotating shaft 75 to move in the through groove 83. After determining the position of the saddle 4, start the forward and reverse motor 22, so that the forward and reverse motor 22 drives the connecting block 29 to rotate, and then drives the lower limit block 23 located above the connecting block 29 to rotate. At this time, the second connecting arm 74 moves downward under the drive of the first connecting arm 71, so that the baffle plate 84 rotates, thereby opening the discharge port, and then the cross-tie rod located in the feeding mechanism 8 will roll onto the baffle plate 84, and then roll onto the connecting mechanism 7, and finally fall into the lower limit block 23;

[0053] After that, the forward and reverse motor 22 is reversed to drive the lower limit block 23 to reset, and the material blocking plate 84 is reset to prevent other tie rods from rolling out. Then the cylinder 2 11 is started, and the cylinder 2 11 drives the upper limit block 12 to descend, and descends until the upper limit block 12 is in contact with the lower limit block 23. At this time, the chuck assembly 1 25 and the chuck assembly 2 13 are combined into a chuck, and the bevel gear assembly 1 24 and the bevel gear assembly 2 14 are combined into a bevel gear 1 26. Then the staff operates the chuck to clamp the tie rod.

[0054] Then, the spindle motor 57 is started, and the spindle motor 57 drives the bevel gear 2 to rotate through the gear box 58, so that the bevel gear 2 drives the bevel gear 1 26 to rotate, and the chuck fitted with the bevel gear 1 26 will also rotate, thereby rotating the cross-rod, which is convenient for subsequent processing work. When it is necessary to adjust the processing position, the position of the slide 51 and the slide plate 52 can be adjusted, and the height of the cross-rod can be adjusted through the cylinder 1 20 and the cylinder 2 11, so that the present solution can process the cross-rod in the x-axis, y-axis and z-axis. According to different work requirements, those skilled in the art can install different tools on the tool holder 54 when performing different processing work, so that the tools on the two tool holders 54 can process the cross-rods respectively at the same time;

[0055] After the processing is completed, the cylinder 1 20 is activated to reset the upper limit block 12. Then, one of the cylinders 1 20 is activated to raise one of the lower limit blocks 23. The height of the other lower limit block 23 remains unchanged, causing the tie rod to tilt and then slide off the lower limit block 23, completing the unloading work. No manual loading or unloading is required.

[0056] The above embodiments are only preferred embodiments of the present invention. Those skilled in the art can derive other embodiments from the above embodiments without creative work. Therefore, the scope of protection of this application is not only the above embodiments, but also the scope consistent with the principles and features of the technical solution of this application.
