Description

Technical Field

[0001] The invention relates to the field of bearing seat processing, and in particular to a bearing seat processing and fixing device. Background Art

[0002] The bearing seat is a special component used to support and position bearings in mechanical equipment. It is usually composed of a bearing seat body and a through hole provided on the bearing seat body for setting the bearing. The bearing seat plays a vital role in maintaining the normal operation of the bearing. When in use, the bearing seat usually needs to be processed accordingly according to the application scenario to enhance its corresponding functionality. For example, the invention patent with patent application number 201310223704.0 provides a gear pump bearing seat structure, which requires multiple structures such as a sealing ring mounting groove, a driving shaft mounting hole, a driven shaft mounting hole, and a weight reduction groove to be provided on the bearing seat body. At the same time, the two ends of the bearing seat need to be processed to form a cross-sectional structure so that it can better fit the mechanical housing.

[0003] When the bearing seat is processed, it needs to be fixed so as to facilitate processing. In the prior art, a clamp with good clamping force is usually used to clamp the side wall of the bearing seat so as to fix the bearing seat.

[0004] However, for the bearing seat with a relatively small structure, it is difficult to fix the fixture due to its small size and smooth surface. At the same time, it is easy to cover most of the surface area of ​​the bearing seat when clamping and fixing, which makes the surface processing of the bearing seat difficult. It is even necessary to change the clamping angle multiple times to process the surface of the bearing seat in turn, which is time-consuming and labor-intensive and is not conducive to improving production efficiency. Summary of the invention

[0005] In view of this, the present invention provides a bearing seat processing and fixing device to solve the above problems.

[0006] A processing and fixing device for a bearing seat, comprising a table, a lifting drive device fixedly connected to the table, and a rotation positioning mechanism arranged on one side of the lifting drive device. The lifting drive device is used to drive the rotation positioning mechanism to move up and down. The rotation positioning mechanism comprises a connecting seat fixedly connected to the lifting drive device, two positioning connecting rods rotatably connected to the connecting seat, and a spring arranged between the two positioning connecting rods. Two positioning holes adapted to the positioning connecting rod are arranged on the table. The positioning connecting rod comprises a connecting rod body, a mounting block arranged at one axial end of the connecting rod body, a rotating pivot arranged on the mounting block, a spring connecting shaft arranged on the connecting rod body, a straightening block arranged on one side of the connecting rod body, and a clamping head arranged at the other axial end of the connecting rod body. The positioning connecting rod is rotatably mounted on the connecting seat through the rotating pivot. The straightening block and the spring connecting shaft are separated on both sides of the connecting rod body in the radial direction. The radial dimension of the straightening block along the positioning hole should be such that the central axis of the connecting rod body is parallel to or coincides with the central axis of the positioning hole when the straightening block is inserted into the positioning hole.

[0007] Furthermore, the lifting drive device includes a cylinder and at least two connecting columns fixedly arranged on the cylinder.

[0008] Furthermore, the connecting seat includes a connecting seat body, a cylinder mounting hole arranged on the connecting seat body, and two connecting rod mounting grooves symmetrically arranged on both sides of the cylinder mounting hole.

[0009] Furthermore, the shape of the mounting block is consistent with the shape of the connecting rod mounting groove, and the outer contour length of the mounting block is smaller than the inner contour length of the connecting rod mounting groove.

[0010] Furthermore, the maximum outer diameter of the connecting rod body is smaller than the diameter of the positioning hole.

[0011] Furthermore, the clamping head is arranged at the axial end of the connecting rod body, the maximum diameter of the clamping head is larger than the diameter of the connecting rod body, and the clamping head is eccentrically arranged with the connecting rod body. At the same time, the clamping head is flush with the connecting rod body on the side facing the spring connecting shaft, and forms a step on the side facing the straightening block.

[0012] Furthermore, the step is spaced apart from the straightening block to form a clearance opening, and the distance between the step and the straightening block is greater than the axial depth of the positioning hole.

[0013] Furthermore, the table top includes a table top body, a spring avoidance groove arranged on the table top body, a bearing seat positioning platform arranged on one side of the table top body, and the positioning hole is arranged on the bearing seat positioning platform.

[0014] Furthermore, the two positioning connecting rods are arranged in a mirror image with the central axis of the cylinder mounting hole as the axis.

[0015] Furthermore, the central axis of the rotating pivot is spaced apart from the central axis of the positioning hole.

[0016] Compared with the prior art, the processing and fixing device of the bearing seat provided by the present invention includes a table, a lifting drive device fixedly connected to the table, and a rotation positioning mechanism arranged on one side of the lifting drive device. The rotation positioning mechanism includes a connecting seat fixedly connected to the cylinder, two positioning connecting rods rotatably connected to the connecting seat, and a spring arranged between the two positioning connecting rods. A rotating pivot, a spring connecting shaft, a straightening block, and a clamping head are arranged on the positioning connecting rod. The spring is located between the two positioning connecting rods, and because the central axis of the rotating pivot is spaced apart from the central axis of the positioning hole, the positioning connecting rod will deflect under the action of the spring when it moves up and down in the positioning hole. Specifically, when the cylinder drives the positioning connecting rod to move downward, the straightening block slides out of the positioning hole during the downward movement. At the same time, since the diameter of the connecting rod body is smaller than the diameter of the positioning hole, when the two positioning connecting rods move downward to the clearance opening, they will be stretched outward under the action of the spring elastic force, and rotate and tilt to form an "outward eight-character" shape. At this time, the central axis of the connecting rod and the central axis of the positioning hole are in a cross relationship, so that the step can be pressed against the positioning edge of the bearing seat to fix the bearing seat on the bearing seat positioning platform. Therefore, it can be seen that the processing and fixing device of the bearing seat can not only stably fix the bearing seat, but also fix the bearing seat only through the side of the bearing seat that contacts the bearing seat positioning platform, so as not to affect the processing of the end face or side wall of the bearing seat. In this way, it is avoided that most of the end face or side wall of the bearing seat is covered during clamping and fixing, which leads to processing difficulties, and even requires multiple changes of the clamping angle to process the surface of the bearing seat in turn, thereby greatly reducing the processing time of the bearing seat and facilitating the improvement of production efficiency.

[0025] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0026] like Figures 1 to 8 As shown, it is a schematic diagram of the structure of a processing and fixing device for a bearing seat provided by the present invention. The processing and fixing device for the bearing seat is used to fix a bearing seat 10 so as to facilitate the processing of the end face of the bearing seat 10. The processing and fixing device for the bearing seat includes a table 20, a lifting drive device 30 fixedly connected to the table 20, and a rotation positioning mechanism 30 arranged on one side of the lifting drive device 30. It can be imagined that the processing and fixing device for the bearing seat should also include some other functional components, such as mounting components, assembly components, etc., which are all prior arts known to those skilled in the art and will not be elaborated here.

[0027] like Figure 8As shown, the bearing seat 10 is in the shape of a figure 8 as a whole, and is an important mechanical element for supporting and positioning the bearing. The bearing seat 10 includes a bearing seat body 11, two through holes 12 arranged on the bearing seat body 11, and a positioning edge 13 arranged at one end of the through hole 12. The bearing seat body 11 can be made of different materials such as aluminum alloy, cast steel, cast iron, etc. according to the use environment of the bearing 10. The through hole 12 is used to install and fix the bearing. The positioning edge 13 is arranged at one end of the through hole 12, and is used to position the parts such as bearings installed in the through hole 12 during use. The bearing seat 10 itself is a prior art known to those skilled in the art, and will not be described in detail here.

[0028] The table 20 includes a table body 21 , a spring avoidance groove 22 arranged on the table body 21 , a bearing seat positioning platform 23 arranged on one side of the table body 21 , and two positioning holes 24 arranged on the bearing seat positioning platform 23 .

[0029] The table body 21 may be a square plate and should be a part of a machine tool, which is used to support and place the bearing seat 10 so as to facilitate the processing of the bearing seat 10 .

[0030] The spring avoidance groove 22 is provided on the table body 21 and penetrates the table body 21. The spring avoidance groove 22 can be provided in an elliptical shape, and its size should be adapted to the size of the rotation positioning mechanism 40, so that the spring 43 can be accommodated during the extension and retraction process of the positioning link 42 described below. The size of the spring avoidance groove 22 should form a clearance space when the positioning link 42 is stretched by the spring 43, so as to facilitate the rotation positioning mechanism 40 to complete the positioning action of the bearing seat 10.

[0031] The bearing seat positioning platform 23 is fixedly arranged on one side of the table body 21 and is used to place the bearing seat 10. The shape and size of the bearing seat positioning platform 23 are adapted to the shape and size of the bearing seat 10, so that a position comparison can be formed when placing the bearing seat 10, thereby quickly adjusting the position of the bearing seat 10, facilitating the rapid positioning of the bearing seat 10, and also facilitating the processing of the outer side wall of the bearing seat 10.

[0032] The diameter of the positioning hole 24 matches the size of the positioning link 42 of the rotation positioning mechanism 40, and is connected to the spring avoidance groove 22, so that the positioning link 42 of the rotation positioning mechanism 40 passes through the spring avoidance groove 22 and then extends from the positioning hole 24 and is inserted into the bearing seat 10 to clamp and position the bearing seat 10. Preferably, the positioning hole 24 is rounded at one end facing the rotation positioning mechanism 40 to form a guide, so as to facilitate the positioning link 42 of the rotation positioning mechanism 40 to enter and exit the positioning hole 24.

[0033] The lifting drive device 30 is used to drive the rotary positioning mechanism 40 to reciprocate and extend, and includes a cylinder 31 and at least two connecting columns 32 fixedly disposed on the cylinder 31 .

[0034] The cylinder 31 is fixedly connected to the side of the table body 21 opposite to the bearing seat positioning platform 23 through the connecting column 32. The output shaft of the cylinder 31 is fixedly connected to the rotation positioning mechanism 40, thereby driving the rotation positioning mechanism 40 to slide up and down along the axial direction of the connecting column 32.

[0035] The connecting column 32 is symmetrically arranged on both sides of the cylinder 31, one end of which is fixedly connected to the cylinder 31, and the other end is fixedly connected to the table 20, so that the cylinder 22 is fixedly arranged on the table 20. In this embodiment, four connecting columns 32 are arranged, and the four connecting columns 32 are symmetrically arranged on both sides of the cylinder 31, so as to ensure the stability of the cylinder 31 during operation.

[0036] The rotation positioning mechanism 40 includes a connection seat 41 fixedly connected to the cylinder 31 , two positioning connecting rods 42 rotatably disposed on the connection seat 41 , and a spring 43 disposed between the two positioning connecting rods 42 .

[0037] like Figure 5 As shown, the connecting seat 41 includes a connecting seat body 411 , a cylinder mounting hole 412 arranged on the connecting seat body 411 , and two connecting rod mounting grooves 413 symmetrically arranged on both sides of the cylinder mounting hole 412 .

[0038] The connecting seat body 411 may be a cuboid structure, and one side thereof facing the cylinder 31 is fixedly connected to the cylinder 31 through the cylinder mounting hole 412 , so as to move up and down under the drive of the cylinder 31 .

[0039] The cylinder mounting hole 412 is adapted to the output shaft of the cylinder 31 and is centrally arranged on the connecting seat body 411, so that the connecting seat body 411 is subjected to balanced force and moves stably. After the output shaft of the cylinder 31 is inserted into the cylinder mounting hole 412, it can be fixedly connected by a bolt (not shown).

[0040] The two connecting rod installation grooves 413 are symmetrically arranged on both sides of the cylinder installation hole 412, and are used to install the positioning connecting rod 42. The specific connection method will be described below in conjunction with the positioning connecting rod 42. The structure of the connecting rod installation groove 413 is matched with the structure of the positioning connecting rod 42, so that the positioning connecting rod 42 can be installed on the connecting seat 41. In order to enable the positioning connecting rod 42 to rotate, the connecting rod installation groove 413 is rectangular to provide a larger space for the positioning connecting rod 42 to rotate.

[0041] There are two positioning links 42, and the structures of the two positioning links 42 are completely the same. In the arrangement direction of the two positioning links 42, the two positioning links 42 are mirror-imaged with the central axis of the cylinder mounting hole 412 as the axis. Figure 3 As shown. The following takes a positioning link 42 as an example to illustrate its structure. Figure 6 As shown, the positioning link 42 includes a link body 421, a mounting block 422 arranged at one axial end of the link body 421, a rotating pivot 423 arranged on the mounting block 422, a spring connecting shaft 424 arranged on the link body 421, a straightening block 425 arranged on one side of the link body 421, and a clamping head 426 arranged at the other axial end of the link body 421.

[0042] The connecting rod body 421 is a column, one end of which is movably connected to the connecting seat 41 through the mounting block 422, and the other end is inserted into the positioning hole 24 of the table 20. The cross section of the connecting rod body 421 can be circular or elliptical. The maximum outer diameter of the connecting rod body 421 is smaller than the diameter of the positioning hole 24, so that the connecting rod body 421 can move in the radial direction or axial direction of the positioning hole 24.

[0043] The shape of the mounting block 422 may be consistent with the shape of the connecting rod mounting groove 413, and the outer contour length of the mounting block 422 is smaller than the inner contour length of the connecting rod mounting groove 413, so that a gap is formed between the two ends of the mounting block 422 and the connecting seat body 411, so that the mounting block 422 can rotate in the connecting rod mounting groove 413. The positioning connecting rod 42 is mounted in the connecting rod mounting groove 413 through the rotating pivot 423, so that the mounting block 422 can rotate. Due to the existence of the gap, when the positioning connecting rod 42 moves downward, it can be opened and rotated to both sides under the action of the elastic force of the spring 43 to clamp and position the bearing seat 10. The size of the gap between the two ends of the mounting block 422 and the connecting seat body 411 may be set according to the rotation amplitude of the positioning connecting rod 42.

[0044] The rotating pivot 423 is perpendicular to the plane where the rotation direction of the positioning link 42 is located and is arranged on both sides of the mounting block 422. It can be a cylindrical structure, so as to facilitate the positioning link 42 to be rotatably installed in the connecting rod mounting groove 413. The central axis of the rotating pivot 423 is spaced from the central axis of the positioning hole 24, so that the positioning link 42 can be deflected under the action of the spring 43 when it moves up and down in the positioning hole 24. At the same time, as long as the mounting block 422 deflects a relatively small angle, the connecting rod body 421 can deflect a relatively large angle, thereby reducing the volume of the mounting block 422, thereby reducing the volume of the entire fixing device. It can be imagined that, in the case of not being restricted by volume, the central axis of the rotating pivot 423 can intersect with the central axis of the positioning hole 24.

[0045] The spring connecting shaft 424 is disposed on the opposite side of the two positioning connecting rods 42 and is located on the side of the connecting rod body 421 facing away from the straightening block 425. The spring connecting shaft 424 may be a cylindrical structure, which is used to mount and fix the spring 43 between the two positioning connecting rods 42.

[0046] The straightening block 425 is arranged on the side of the connecting rod body 421 facing away from the spring connecting shaft 424, that is, the straightening block 425 and the spring connecting shaft 424 are separated on both sides of the connecting rod body 421 in the radial direction. Since the central axis of the rotating pivot 423 and the central axis of the positioning hole 24 are arranged at intervals, and the diameter of the positioning hole 24 is larger than the diameter of the connecting rod body 421, if there is no straightening block 425, the connecting rod body 421 will be deflected under the action of the spring 43, so that the central axis of the connecting rod body 421 is not parallel or coincident with the central axis of the positioning hole 24. Therefore, the function of the straightening block 425 is that when the straightening block 425 is inserted into the positioning hole 24, the central axis of the connecting rod body 421 is parallel or coincident with the central axis of the positioning hole 24, so that the end of the bearing seat 10 with the positioning edge 13 can be sleeved on the connecting body 421. Therefore, the radial dimension of the straightening block 425 along the positioning hole 24 should be such that the central axis of the connecting rod body 421 is parallel to or coincides with the central axis of the positioning hole 24 when the straightening block 425 is inserted into the positioning hole 24. In order to facilitate the straightening block 425 to be inserted into or slide out of the positioning hole 24, a guiding inclined surface is provided on the side of the straightening block 425 facing the clamping head 426.

[0047] The clamping head 426 is arranged at the end of the connecting rod body 421 in the axial direction. The maximum diameter of the clamping head 426 is greater than the diameter of the connecting body 421, and the clamping head 426 is eccentrically arranged with the connecting body 421. At the same time, the clamping head 426 is flush with the connecting body 421 on the side facing the spring connecting shaft 424, and a step 427 is formed on the side facing the straightening block 425. The step 427 is used to clamp the positioning edge 13 of the bearing seat 10 between the clamping head 426 and the bearing seat positioning platform 23. The maximum diameter of the clamping head 426 is smaller than the diameter of the positioning hole 24, so that it can pass through the positioning hole 24, which is convenient for assembling the fixing device. At the same time, the maximum diameter of the clamping head 426 is smaller than the diameter of the space surrounded by the positioning edge 13, so that the clamping head 426 can pass through the space surrounded by the positioning edge 13. In the axial direction of the connecting rod body 421 , the step 427 is spaced apart from the straightening block 425 , thereby forming a clearance opening 428 . The minimum spacing distance between the step 427 and the straightening block 425 is greater than the axial depth of the positioning hole 24 .

[0048] The two ends of the spring 43 are respectively fixedly sleeved on the spring connecting shaft 424, and are used to provide elastic force to make the two positioning connecting rods 42 open outwards and rotate and tilt. The size of the spring 43 can be selected according to the distance between the connecting rod bodies 42 and the elastic force requirements.

[0049] When the positioning link 42 is in an unclamped state, the straightening block 425 is inserted into and extends out of the positioning hole 24. At this time, the central axis of the connecting rod body 421 is parallel to or coincides with the central axis of the positioning hole 24 to form a vertical state. Then the bearing seat 10 is sleeved on the positioning link 42, and the clamping head 426 passes through the space surrounded by the positioning edge 13. After adjusting the position of the bearing seat 10, the cylinder 31 drives the positioning link 42 to move downward. During the downward movement, the straightening block 425 slides out of the positioning hole 24 until the clamping head 426 abuts against the positioning edge 13. Since the diameter of the connecting rod body 421 is smaller than the diameter of the positioning hole 24, when the two positioning links 42 move down to the clearance opening 428, they will be stretched outward under the action of the elastic force of the spring 43, and rotate and tilt to form an "outward eight" shape, such as Figure 2 As shown. At this time, the central axis of the connecting rod 42 and the central axis of the positioning hole 24 are in a cross relationship, and the angle between them can be between 10-15 degrees, so that the step 427 can abut against the positioning edge 13 of the bearing seat 10 to fix the bearing seat 10 on the bearing seat positioning platform 23. When the end face or side wall of the bearing seat 10 is processed, the cylinder 31 drives the positioning connecting rod 42 to move up again. The spring 43 is compressed during the upward movement of the two positioning connecting rods 42, and the straightening block 425 is inserted into the positioning hole 24 again, so that the two positioning connecting rods 42 are restored from the inclined external eight-shaped state to the parallel state, that is, the connecting rod body 421 is parallel or coincident with the central axis of the positioning hole 24 again. At this time, the position of the clamping head 426 is the same as the unclamped position, as shown in FIG. Figure 3 As shown, the step 427 is separated from the bearing seat 10, thereby facilitating the removal of the bearing seat 10.

[0050] Compared with the prior art, the processing and fixing device of the bearing seat provided by the present invention includes a table 20, a lifting drive device 30 fixedly connected to the table 20, and a rotation positioning mechanism 40 arranged on one side of the lifting drive device 30. The rotation positioning mechanism 40 includes a connecting seat 41 fixedly connected to the cylinder 31, two positioning connecting rods 42 rotatably connected to the connecting seat 41, and a spring 43 arranged between the two positioning connecting rods 42. A rotating pivot 423, a spring connecting shaft 424, a straightening block 425, and a clamping head 426 are arranged on the positioning connecting rod 42. The spring 43 is located between the two positioning connecting rods 42, and because the central axis of the rotating pivot 423 is spaced apart from the central axis of the positioning hole 24, the positioning connecting rod 42 will deflect under the action of the spring 43 when it moves up and down in the positioning hole 24. Specifically, when the cylinder 31 drives the positioning link 42 to move downward, the straightening block 425 slides out of the positioning hole 24 during the downward movement. At the same time, since the diameter of the link body 421 is smaller than the diameter of the positioning hole 24, when the two positioning links 42 move downward to the clearance opening 428, they will be stretched outward under the elastic force of the spring 43, and rotate and tilt to form an "outward eight-character" shape. At this time, the central axis of the link 42 and the central axis of the positioning hole 24 are in a cross relationship, so that the step 427 can abut against the positioning edge 13 of the bearing seat 10 to fix the bearing seat 10 on the bearing seat positioning platform 23. Therefore, it can be seen that the processing and fixing device of the bearing seat can not only stably fix the bearing seat 10, but also fix the bearing seat 10 only through the side of the bearing seat 10 that contacts the bearing seat positioning platform 23, so as not to affect the processing of the end face or side wall of the bearing seat 10. This avoids covering most of the end face or side wall of the bearing seat 10 when clamping and fixing, which would cause processing difficulties and even require changing the clamping angle multiple times to process the surface of the bearing seat 10 in turn, thereby greatly reducing the processing time of the bearing seat 10 and facilitating the improvement of production efficiency.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
