Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing broaching machine feeding device. Background Technology
[0002] The bearing bush is the part of a sliding bearing that contacts the journal. It is shaped like a tile-like semi-cylindrical surface, which is very smooth and is generally made of wear-resistant materials such as bronze or anti-friction alloys.
[0003] In the manufacturing process of bearing bushes, the radial height of the bearing bush needs to be machined using a bearing bush broaching machine. This involves cutting the two end faces of the semi-circular bearing bush using the broaching machine, with the cutting amount on each end face varying depending on the requirements. Therefore, during machining, the bearing bush needs to be fed onto the broaching machine's die at a specific angle, according to the different cutting requirements of the two end faces. This allows the two ends of the bearing bush to protrude from the die by different cutting amounts, and then the broaching tool of the bearing bush broaching machine performs the cutting. However, the current structure of the feeding device in existing bearing bush broaching machines is fixed, making it impossible to flexibly adjust the angle of the feeding. This means that different feeding devices need to be changed when machining different types of bearing bushes, which is cumbersome and significantly impacts processing efficiency.

Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0045] This utility model provides a bearing broaching bed feeding device, such as Figure 1 and Figure 2As shown, the bearing broaching machine feeding device includes a mounting base 10, a rotating adjustment base 20, an adjustment module 30, a guide rail base 40, and a drive device. The rotating adjustment base 20 is rotatably connected to the mounting base 10 at its center. The adjustment module 30 includes a first adjustment block 31 and a second adjustment block 32, which are respectively fixed to the top of the mounting base 10. The first adjustment block 31 is located on the left side of the mounting base 10, and the second adjustment block 32 is located on the right side of the mounting base 10. Specifically, a first adjustment screw 311 is threaded onto the first adjustment block 31. The lower end of an adjusting screw 311 abuts against the top left side of the rotating adjusting seat 20. A second adjusting screw 321 is threaded onto the second adjusting block 32, and the lower end of the second adjusting screw 321 abuts against the top right side of the rotating adjusting seat 20. The guide rail seat 40 is connected to the rotating adjusting seat 20. A feeding plate 401 is slidably provided on the guide rail seat 40. The feeding plate 401 is provided with a material placement station, and a clearance groove 4010 is provided at the material placement station. The driving device is connected to the feeding plate 401 and is used to drive the feeding plate 401 to slide back and forth along the guide rail seat 40.
[0046] The beneficial effects of the bearing broaching bed feeding device of this utility model are: when in use, such as Figure 1As shown, the bearing bush 100 to be processed is placed at the material placement position on the feeding plate 401. When it is necessary to have different cutting amounts at both ends of the bearing bush 100, this can be achieved by turning the first adjusting screw 311 and the second adjusting screw 321. That is, since the middle part of the rotating adjusting seat 20 is rotatably connected to the mounting seat 10, and the lower end of the first adjusting screw 311 on the first adjusting block 31 abuts against the top left side of the rotating adjusting seat 20, and the lower end of the second adjusting screw 321 on the second adjusting block 32 abuts against the top right side of the rotating adjusting seat 20, for example, when it is necessary to have a larger cutting amount on the left end face of the bearing bush and a smaller cutting amount on the right end face of the bearing bush, the first adjusting screw 311 can be turned so that the lower end of the first adjusting screw 311 presses downward against the rotating adjusting seat 20. Correspondingly, the second screw 321 needs to be turned so that the second adjusting screw 321 moves upward by the same distance. Since the middle part of the rotating adjustment seat 20 is rotatably connected to the mounting seat 10, the first adjusting screw 311 will press the left end of the rotating adjustment seat 20 to rotate to the left by a certain angle. Then, the rotating adjustment seat 20 will drive the guide rail seat 40 and the feeding plate 401 to rotate to the left by a certain angle, so that the bearing placed on the feeding plate 401 will also tilt to the left by a certain angle. Then, the driving device drives the feeding plate 401 to move forward and send the bearing 100 on the feeding plate 401 to the bearing positioning mold. Then, the positioning mechanism at the bearing positioning mold positions the bearing 100 on the mold. Since the bearing is fed to the mold at a certain angle to the left, after the bearing is positioned on the mold, the cutting amount of the left end face of the bearing protruding from the mold is greater, and the cutting amount of the right end face of the bearing protruding from the mold is less, so that different cutting amounts can be achieved on the two ends of the bearing. In summary, when it is necessary to adjust the different cutting amounts on the two end faces of the bearing bush, it can be achieved simply by turning the first adjusting screw 311 and the second adjusting screw 321 to adjust the tilt angle of the rotating adjusting seat 20. The operation is simple and quick, and there is no need to change different feeding devices, making production more flexible and greatly improving the processing efficiency of the bearing bush.
[0047] Specifically, it is understandable that a limiting structure is provided around the material placement station to prevent the bearing from sliding forward, backward, left, or right. This is a conventional design in the existing technology, so it will not be elaborated on here.
[0048] Furthermore, such as Figure 1 and Figure 4As shown, in this embodiment, the mounting base 10 includes a fixing block 11 and a connecting block 12. The connecting block 12 is fixedly connected to the fixing block 11 by screws. A connecting hole 120 is provided on the connecting block 12. Correspondingly, a rotating shaft 201 is provided in the middle of the rotating adjustment base 20. The rotating shaft 201 is embedded in the connecting hole 120 on the connecting block 12, and the rotating shaft 201 can rotate relative to the connecting hole 120, that is, the rotating shaft 201 can rotate within the connecting hole 120. In use, when the first adjusting screw 311 and the second adjusting screw 321 are turned, the rotating adjustment base 20 can rotate left and right about the rotating shaft 201 as the pivot point (fulcrum). The structure is simple and the operation is convenient.
[0049] Furthermore, to prevent the feeding plate 401 from being clamped by the upper and lower clamping mechanisms at the bearing positioning mold and unable to move back during feeding, preferably, in this embodiment, the guide rail seat 40 is hinged to the rotation adjustment seat 20, that is, the guide rail seat 40 can rotate up and down relative to the rotation adjustment seat 20. With this structural design, when the bearing 100 is fed above the bearing positioning mold, as... Figure 1 As shown, since a clearance groove 4010 is provided at the material placement station on the feeding plate 401, after the bearing bush 100 is sent to the bearing bush positioning mold, the bearing bush positioning mold will be located in the clearance groove 4010, that is, directly below the bearing bush 100. Then, the top of the bearing bush is pressed down by the upper clamping mechanism at the bearing bush positioning mold, pressing the bearing bush onto the bearing bush positioning mold. At the same time, since the guide rail seat 40, i.e. the feeding plate 401, is hinged to the rotating adjustment seat 20, when the bearing bush is pressed, the feeding plate 401 will rotate downwards accordingly under the drive of the bearing bush 100. At the same time, the driving device drives the feeding plate 401 to move back, thereby preventing the feeding plate from being pressed and unable to be pulled out.
[0050] Specifically, during use, a reset cylinder is connected below the guide rail seat. After the feeding plate is pulled back to its original position, the reset cylinder will lift the guide rail seat 40 upwards, restoring the guide rail seat 40 to a horizontal state, thereby starting the next feeding cycle.
[0051] Furthermore, in this embodiment, the guide rail seat 40 is hinged to the rotation adjustment seat via a copper sleeve. The copper sleeve has good wear resistance, which can reduce wear at the hinge and extend the service life of the parts.
[0052] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the guide rail base 40 includes a left guide rail 41 and a right guide rail 42. The left guide rail 41 is provided with a left sliding groove 411, and the right guide rail 42 is provided with a right sliding groove 421. The feeding plate 401 includes a sliding plate 4011 and a supporting plate 4012. The left side of the sliding plate 4011 is slidably embedded in the left sliding groove 411 on the left guide rail 41, and the right side of the sliding plate 4011 is slidably embedded in the right sliding groove 421 on the right guide rail 43. The first end of the supporting plate 4012 is fixedly connected to the sliding plate 4011, and the material placement station is located at the second end of the supporting plate 4012. Specifically, the driving device is connected to the sliding plate 4011. Therefore, in this embodiment, the left guide rail 41 of the guide rail base 40 is hinged to the left end of the rotating adjustment seat 20 through a left copper sleeve, and the right guide rail 42 of the guide rail base 40 is hinged to the right end of the rotating adjustment seat 20 through a right copper sleeve.
[0053] Furthermore, such as Figure 2 As shown, in this embodiment, the driving device is a driving cylinder 50, which is fixedly connected to the mounting base 10. The piston rod 51 of the driving cylinder 50 is connected to the feeding plate 401, i.e., the slide plate 4011, via a universal joint 52. Through this structural design, the universal joint ensures that when the slide rail base 40 rotates up and down, the feeding plate 401 can adaptively rotate up and down relative to the piston rod.
[0054] In summary, the bearing broaching machine feeding device of this invention allows for adjustments to the cutting amounts required on the two end faces of the bearing simply by turning the first and second adjusting screws to adjust the left and right tilt angles of the rotating adjusting seat. This simple and quick operation eliminates the need to change different feeding devices, making production more flexible and significantly improving bearing processing efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.
[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
