Description

Technical Field

[0001] The present invention relates to the technical field of bearing component production and processing equipment, and more specifically, to a large-scale bearing ring slitting and processing system. Background Art

[0002] Large bearing rings are important components of large industrial bearings. Large bearing rings have the characteristics of large diameters, but the thickness of a single large bearing ring is relatively thin. Therefore, when large bearing rings are initially blanked, they are not formed into blanks with a single bearing ring as a unit (thin thickness makes blanking difficult, and blanks are also prone to deformation and scrap). In actual production, large-thickness ring barrel blanks are first made, and after the initial processing of the shape is completed, they are cut one by one into large-thickness semi-finished bearing rings. The advantages of this are that blanking is more convenient, the deformation of the semi-finished bearing rings is effectively controlled, and the scrap rate in the blanking stage is effectively controlled. The large-thickness ring barrels cut into large-thickness semi-finished bearing rings are not only large in diameter, but also very heavy, which brings great difficulty to the clamping and cutting operations of the large-thickness ring barrels. The company urgently needs to design a production equipment that can safely and conveniently cut large-thickness semi-finished bearing rings, and this case is born. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A large-scale bearing ring slitting processing system includes a slitting table 1 and a lifting device 4. A blank turntable 2 is rotatably installed on the surface of the slitting table 1, and a plurality of blank clamping seats 21 are evenly installed on the blank turntable 2. The thick ring tube blank is fixed on the blank turntable 2 through the blank clamping seats 21. The thick ring tube blank adopts horizontal placement and rotational motion, which is conducive to stable and safe rotation. A slitting tool 3 is also installed on the surface of the slitting table 1. The slitting tool 3 has the ability of lifting and feeding, and can feed and cut the thick ring tube blank in rotation. There are many such slitting tools 3 on the market, which are purchased as finished products, and no further introduction is made here. The lifting device 4 is installed on the side of the slitting table 1. The lifting device 4 is also purchased from existing equipment on the market, and its specific structural part is introduced in detail. The lifting device 4 is equipped with a head 41 that can move vertically up and down, and a crossbeam 5 is fixedly connected to the side wall of the head 41. An auxiliary clamp 6 is rotatably installed under the crossbeam 5. The lifting of the head 41 drives the lifting of the crossbeam 5 and the auxiliary clamp 6 to meet the needs of grasping and separating objects. The auxiliary clamp 6 is used to clamp the top of the large thickness coil tube blank, and the blank clamp seat 21 is used to clamp the bottom of the large thickness coil tube blank. The auxiliary clamp 6 and the blank clamp seat 21 form corresponding clamping effects at the upper and lower ends. Since the auxiliary clamp 6 can rotate, it does not affect the blank turntable 2 to carry the large thickness coil tube blank. The large thickness coil tube blank is cut by the cutting tool 3 during rotation. After the cutting is completed, the original is still clamped on the blank turntable 2, and the cut part (that is, a single large bearing ring semi-finished product) is held by the auxiliary clamp 6. The design of the auxiliary clamp 6 and the use of horizontal rotary cutting of the large thickness coil tube blank make it possible to complete the cutting operation of the large thickness coil tube blank safely. The cut single large bearing ring semi-finished product can be reliably clamped and taken away, and there will be no safety issues for objects and personnel during the process.

[0025] like Figure 1 As shown, a first motor 11 is installed in the slitting table 1, and the output end of the first motor 11 is connected to the bottom surface of the blank turntable 2. The output end of the first motor 11 is fixedly connected to the central position of the bottom surface of the blank turntable 2. By starting the first motor 11 to drive the rotation of the blank turntable 2, the horizontal rotation movement of the large thickness coil blank is realized.

[0026] like Figure 1 and Figure 2As shown, the auxiliary clamp 6 includes a rotating frame 61 and a tensioning driver 63. The rotating frame 61 is rotatably installed below the crossbeam 5. A plurality of hydraulic elastic clamps 62 are evenly installed along the same circumference at the bottom of the rotating frame 61. The tensioning driver 63 is installed in the rotating frame 61. A plurality of liquid supply elements 64 are installed on the tensioning driver 63. The liquid supply elements 64 are arranged one by one with the hydraulic elastic clamps 62 and are connected to each other by pipelines. The liquid supply element 64 includes a contact rod 641 that is movably installed laterally. The contact rod 641 is transmission connected to the tensioning driver 63, and the contact rod 641 can be contact-driven by the tensioning driver 63 to form the effect of driving the hydraulic elastic clamp 62 to move through the tensioning driver 63. The hydraulic elastic clamp 62 can not only form the effect of clamping the outer wall of the large-thickness coil blank, but also form the effect of loosening the outer wall of the large-thickness coil blank. In the present invention, the crossbeam 5 and the machine head 41 are connected by a flange. This design is to replace the matching auxiliary clamp 6 according to the diameter size of the large-thickness coil blank.

[0027] like Figure 4 As shown, the hydraulic elastic clamp 62 includes a first tube 621, a first piston 622 and a spring 625. The first piston 622 is movably installed in the first tube 621. The outer diameter of the first piston 622 matches the inner cavity size of the first tube 621. The first piston 622 can guide the lateral movement in the first tube 621. A first liquid cavity 623 is provided on one side of the first piston 622. A push clamp rod 624 is fixedly connected to the other side of the first piston 622. One end of the push clamp rod 624 extends to the outside of the first tube 621 and is connected to a clamp block 6241. The clamp block 6241 is arranged toward the outer wall of the thick ring tube blank. The first liquid cavity 623 is filled with a driving liquid. When the driving liquid in the first liquid cavity 623 becomes more, It will push the first piston 622 to move toward the push and clamp rod 624, and the push and clamp rod 624 and the clamp block 6241 will move toward the outer wall of the thick coil blank, and finally the clamp block 6241 will be clamped on the outer wall of the thick coil blank. The spring 625 is sleeved on the outside of the push and clamp rod 624, and the spring 625 is installed in the first tube 621. One end of the spring 625 is connected to the first piston 622, and the other end is connected to the end of the inner cavity of the first tube 621. When the push and clamp rod 624 and the clamp block 6241 move toward the outer wall of the thick coil blank, the spring 625 will be compressed. In the present invention, the number of hydraulic elastic clamps 62 should be designed to be large, at least 8 or more, so that the holding force is evenly distributed and the clamping state is reliable.

[0028] like Figure 4As shown, the liquid supply element 64 also includes a second tube 642 and a second piston 643. The second piston 643 is movably installed in the second tube 642. The outer diameter of the second piston 643 matches the inner cavity size of the second tube 642. The second piston 643 can guide the lateral movement in the second tube 642. A second liquid cavity 644 is provided on one side of the second piston 643, and a contact rod 641 is connected to the other side of the second piston 643. The present invention forms a one-to-one connection effect between the liquid supply element 64 and the hydraulic elastic clamp 62. Specifically, the second liquid cavity 644 of the second tube 642 is connected to the first liquid cavity 623 of the first tube 621 through a pipeline. That is to say, the first The driving liquid in the liquid chamber 623 and the second liquid chamber 644 can circulate with each other. When the contact rod 641 is forced to move toward the second liquid chamber 644, the driving liquid in the second liquid chamber 644 can push to the first liquid chamber 623, and the driving liquid in the first liquid chamber 623 becomes more, and finally the spring 625 is compressed, and the hydraulic elastic clamp 62 forms a clamping effect. After the contact rod 641 loses the force, the first piston 622 moves toward the first liquid chamber 623 under the elastic force of the spring 625, and the driving liquid in the first liquid chamber 623 is pushed back to the second liquid chamber 644. Under this effect, the second piston 643 and the contact rod 641 move in opposite directions, and the contact rod 641 gradually extends outward.

[0029] As can be seen from the above, the clamping and loosening of the hydraulic elastic clamp 62 can be reflected in the lateral movement direction of the contact rod 641. The contact rod 641 is controlled by the loosening and loosening driver 63 in the present invention. Figure 2 As shown, the tension driver 63 includes a fixed seat 631, a driving block 632 and a push cylinder 633. The fixed seat 631 is fixedly installed in the rotating frame 61. A conical cavity 6311 is provided in the fixed seat 631. The driving block 632 has a conical shape. The size of the driving block 632 matches the conical cavity 6311. A rod shaft 6321 is connected to the top of the driving block 632. The push cylinder 633 is fixedly installed on the crossbeam 5. The push cylinder 633 is installed vertically downward. The piston rod of the push cylinder 633 penetrates the rotating frame 61 and is rotatably connected to the rod shaft 6321 of the driving block 632. In the present invention, the push cylinder 6 33 only plays the role of driving the driving block 632 to rise and fall vertically. Since the piston rod of the push cylinder 633 is rotationally connected to the rod shaft 6321, the installation of the push cylinder 633 does not affect the rotation of the auxiliary clamp 6 along with the thicker ring tube blank. During the slitting operation, the auxiliary clamp 6 can always keep the thicker ring tube blank in a clamping state. In the present invention, the contact rod 641 of the liquid supply element 64 extends toward the conical outer wall of the driving block 632. The contact rod 641 is transmission-connected to the driving block 632, and the lateral movement of the contact rod 641 is driven by the vertical lifting movement of the driving block 632.

[0030] like Figure 2 and Figure 3As shown, a plurality of drive rod grooves 6322 are provided on the conical outer wall of the driving block 632, and the drive rod grooves 6322 and the contact rod 641 are arranged in a one-to-one correspondence. The extended end of the contact rod 641 is connected to a spherical rod head 6411, and the spherical rod head 6411 is inserted into the drive rod groove 6322. The design of the spherical rod head 6411 is more conducive to contact driving. Since the driving block 63 is conical, when the driving block 632 moves vertically downward, the drive rod groove 6322 can form a driving force for the contact rod 641 to move toward the second liquid chamber 644. As the driving block 632 moves downward all the way, the driving liquid in the second liquid chamber 644 can continuously push to the first liquid chamber 623, and the hydraulic elastic clamp 62 forms a gradually enhanced clamping effect. Since the driving block 63 is installed for vertical movement, even in the case of power failure, the driving The moving block 63 can also rely on gravity to keep it always downward. The downward state of the driving block 63 can ensure that the hydraulic elastic clamp 62 always has a clamping force. In other words, even if there is an unexpected power outage, the hydraulic elastic clamp 62 can always clamp the workpiece. In this way, the safety of the auxiliary clamp 6 is greatly improved. To loosen the hydraulic elastic clamp 62, the driving block 632 must be pulled upward by the push cylinder 633. After the driving block 632 moves upward, a gap is formed between the driving rod groove 6322 and the contact rod 641, and the contact rod 641 loses its thrust. Then, under the action of the elastic force of the spring 625, the driving liquid refluxes, and the contact rod 641 and the push clamp rod 624 both move in the opposite direction. The auxiliary clamp 6 loses its clamping force. In this state, the clamping pre-operation or the placement operation of the large bearing ring semi-finished product after cutting can be performed.

[0031] like Figure 1 As shown, a bracket 51 is installed on the crossbeam 5, and a speed sensor 52 is installed at the bottom of the bracket 51. The speed sensor 52 is facing the outer wall of the part that needs to be cut of the large-thickness coil blank. The speed sensor 52 can detect the speed of the large-thickness semi-finished bearing ring cut. After a part of the large-thickness coil blank is cut, the part (i.e., a single large-sized bearing ring semi-finished product) will lose its rotational force and the speed will gradually decrease. After the speed sensor 52 detects it, it can be proved that the cutting operation has been completed. The auxiliary clamp 6 can rise and rotate to quickly take away the cut single large-sized bearing ring semi-finished product. After taking away the cutting part, the auxiliary clamp 6 returns to clamp again, and then the next layer of cutting operation can be carried out again. The present invention can meet the continuous cutting operation requirements of large-sized bearing ring semi-finished products.

[0032] like Figure 1As shown, a steering device 7 is installed below the lifting device 4, and the steering device 7 includes a base 71, a second motor 72 and a steering wheel 73. The steering wheel 73 is rotatably installed on the top of the base 71, and the output end of the second motor 72 is fixedly connected to the steering wheel 73. The lifting device 4 is fixedly installed on the steering wheel 73. The second motor 72 can drive the steering wheel 73 to rotate when it is started. After the steering wheel 73 rotates, the lifting device 4 and the auxiliary clamp 6 can change direction, and the cut single large bearing ring semi-finished product can be quickly taken away from the slitting station to meet the orderly outer side placement requirements. After the placement is completed, the steering wheel 73 rotates in the opposite direction to reset the auxiliary clamp 6.

[0033] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
